Introduction : ThinkDesign is a world-renowned 3D modeling software that combines industrial design and engineering design. In May 2008, Extech successfully introduced the software and had full intellectual property and full source code. ThinkDesign covers the whole process of product development, has an integrated modeling environment and a variety of modeling methods, and has been loved and praised by tens of thousands of users around the world. The automotive industry is one of the key industries that ThinkDesign focuses on, and it has many unique features that can help automotive manufacturers to develop and design. This article takes the ThinkDesign project of a domestic auto company as an example to briefly describe the application of ThinkDesign in the automotive industry. Company Profile The Group Co., Ltd. is a well-known domestic enterprise with an output value of nearly one billion yuan and more than 1,000 employees. The company has been engaged in the production of raw and finished vehicles and auto parts for many years. It has nearly ten subsidiaries including special vehicles, light vehicles, axle plants, frame plants, interior parts, auto parts and real estate. The main products include light trucks, mobile stage vehicles, mobile vending carts, mobile reading vehicles, electric vehicles and other complete vehicles as well as accessories such as frames, axles and seats. (1) The design process is not continuous Before the introduction of ThinkDesign 3D design system, the company used AutoCAD, UG, Pro/E and other design products. Different departments and different designers often use different 3D design software, and use DWG files as the general medium for information transmission. Due to the barrier of different CAD systems, the entire design process has a fault, 3D data can not be fully utilized, and there is a lot of duplication of labor in the entire design process. ThinkDesign is a 3D CAD software covering three stages of industrial design, engineering design and tool design. It supports the entire design process from the beginning of a sketch to the mold design required for processing products (as shown in Figure 1). Data transfer between departments can be performed on the same CAD platform. The 3D model completed by the conceptual designer can be directly passed to the engineering designer, and the model after the engineering design is completed can be directly transmitted to the craft designer. Processes that previously required multiple CAD systems to complete are now available in a CAD system. The flow of data throughout the process is smooth and secure, and there is no need to worry about the data loss of the model transition between different CAD systems, and there is no need to rebuild the model. Figure 1 Automotive development process (2) There is a large amount of 2D data to be utilized Like many manufacturing companies in China, after decades of accumulation, the company has a large amount of 2D historical data. With the continuous development of computer technology in manufacturing applications, the demand for 3D models is increasing. In addition, from the inheritance of product design, it is also necessary to quickly and effectively utilize 2D historical data to shorten the design cycle and speed up the market. ThinkDesign's 2D to 3D function just happens to solve this problem. ThinkDesign can directly read files in DWG format without loss, and can recognize various graphic elements such as layers, line types, Chinese characters, sizes, and blocks in DWG files. The DWG file can be directly dragged and dropped into the 3D environment, and the 3D model can be quickly generated by using various graphic information. ThinkDesign adopts an interactive conversion method, which fully exerts the leading role of people in the conversion process, and abandons the fully automatic conversion method, thus adapting to any complicated engineering drawings. Figure 2 shows the converted model of a part. This model can also be modified if there are new design requirements. Figure 2 2D to 3D example (3) Difficulties in building complex parts In the design of automobiles, there are a large number of auto parts as shown in Fig. 3, which have the characteristics of curved surfaces: complex thin-walled structure and physical characteristics: a large number of holes, grooves, ribs, rounded corners, etc. It is very difficult to construct.

There is a handle installed on the cabinet body in the
cabinet, which is called buckle free handle in the industry. The
aluminum alloy handle is directly installed on the cabinet body, so that
the door panel is clean without handle.
As
shown in the picture, the Black Buckle FREE handle is selected for the
floor cabinet, which is directly embedded into the cabinet body. The
exterior door panel has no raised handle, which is more neat. The handle of the hanging cabinet is directly hidden under the door panel and is not exposed outside. It looks cleaner.
Now let's see what this handle looks like? As shown below:
The
figure above shows the C-type buckle free handle, which is generally
used in the middle of the floor cabinet, drawer, bowl basket or hanging
cabinet. Available colors on the market are gun color, aluminum alloy natural color, or black, and aluminum alloy bright color.

The
above figure is an L-shaped buckle free handle, which is generally used
above the cabinet floor to facilitate the opening of the door panel. colour
The figure above shows the special buckle free handle for the hanging
cabinet, which is specially installed on the bottom plate of the hanging
cabinet.
---------Dimension diagram of buckle free aluminum alloy handle---------------------------
After looking at the appearance of this handle, let's talk about its
installation method and the size of the handle: as shown in the figure
below
This is the first type. The aluminum alloy size of the conventional
circular arc cabinet is 20, the height of the middle type C is 70, the
depth is 23, the height of the floor cabinet L is 55, and the units
above the depth 23 {are mm}
This is the second kind. The right angle buckle free handle.
The aluminum alloy size of the hanging cabinet is 20 deep, the middle
C-type height is 73, and the depth is 26. The height of the L-type
cabinet is 57, and the depth is 26
-----------------------------------------------
Knowing the above dimensions, we will find that the dimensions of the
handle are different. Therefore, during processing and production, we
need to determine the type and size of the handle before cutting the
cabinet.
----Explanation of buckle free handle mode for floor cabinet installation------------
A buckle free handle shall be installed above the floor cabinet, and
there shall be a 30 gap between the door panel and the table
The buckle free handle is installed and needs to be fixed with L-shaped angle iron and cabinet side plate
C-type buckle free handle shall be installed at the middle drawer of the floor cabinet
The
above is the schematic diagram of the cabinet body side plate notch and
the installation handle of the floor cabinet. It should be noted that
the aluminum alloy buckle needs to be fixed with L-shaped angle iron. If
there is a drawer in the middle, or the bowl basket needs to be notched
on the middle side plate, the lower door plate exceeds the buckle by
15, the middle buckle of the middle door plate cover is 15, and 30 needs
to be left between the two door plates. The distance between the uppermost door panel and the table top is also
reserved at 30, which is convenient for opening the door panel.
---Explanation of buckle free handle for hanging cabinet installation-------------------------
The buckle free handle of the hanging cabinet is installed on
the bottom plate of the hanging cabinet, and the bottom plate needs to
be retracted 22 in front
There is a swing door in the middle of the hanging cabinet,
which needs to be equipped with C-type buckle, and a 30 gap is reserved
between the door panels
The
above is the schematic diagram of buckle free handle for hanging
cabinet installation. In conventional installation, the front of the
hanging cabinet bottom plate is shortened by 22, and the aluminum alloy
handle is slotted. If there is an upturned door in the middle of the hanging cabinet, it
is necessary to leave a distance and install L-type handle or C-type
handle. Leave 30 gaps between door panels. The middle fixed laminate shall also be moved upward according to the size of the drawing. {note: the buckle in the middle of the conventional hanging cabinet
needs to open the gap on the side plate. If the side plate of the
hanging cabinet leaks, the gap will not be opened}
-------Precautions in design are as follows:-------------------------------------
Note 1: the exposed part of the ground cabinet needs a light
plate to cover the cabinet incision, and the ground cabinet brace needs
to be installed horizontally, so that the buckle free handle L-shaped
fixed angle iron can be installed on the side plate.
Corner treatment scheme of buckle free handle
The first scheme is recommended at the corner of the buckle
free handle. The price of the handle door panel is high, and the handle
is on the edge of the top door panel.
Note
2: since the buckle free handle is installed on the cabinet, the
cabinet price needs to be high when designing the bowl and basket
cabinet to avoid the plate hitting the buckle free handle as shown in
the above video. The cabinet body can be 700 high, including the table top, and the skirting leg can be set to 850 high floor cabinet.
---------Buckle FREE handles can also be used in other customized furniture
