Previously, many design issues could be fully verified and adjusted after the prototype was produced. However, this model no longer meets the needs of today's fast-paced development cycle. To prevent problems from reaching the market and to provide physical verification and theoretical support in the early design stages, thus avoiding issues from impacting the product development cycle, this car door test bench was developed. The test bench provides physical simulation during the early design phase. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0017] In automotive design, CAE analysis in the early stages can provide some constructive suggestions, but most problems still need to be verified on real vehicles before they can be exposed. Making changes after mold casting will affect project milestones and cost investment. It is necessary to design a test bench that can simulate different car doors and conduct physical simulations in the early design stage to avoid wasting costs and the possibility of problems entering the market.

[0018] like Figure 1 As shown, this utility model embodiment provides a machined structure simulating a car door seal, which is a car door performance test bench 1. The main load-bearing structure is made of steel, while the remaining parts are made of aluminum alloy to ensure lightweighting. The side panel stop 2 and the sealing surface 4 are the core inventive points of this design, while the rest are general structures that are suitable for various car models. In addition, the side panel stop 2 is made of cast aluminum alloy. The sealing surface 4 is made of cast aluminum alloy. The machined structure of this design mainly includes an operating standing platform frame 8, a ramp platform frame 9 installed on the operating standing platform frame 8, an adjustable support mechanism installed on the ramp platform frame 9, and a test bench side panel 7. like Figure 2 As shown, the lead screw mechanism is installed on the frame. The height of the frame body is adjusted via the lead screw mechanism through the height adjustment dials (1A, 1B) on the rotating base; the adjustment range is 300mm. Combined with the handle height adjustment, it can simulate handle heights of 890mm~1270mm. This includes the handle heights of most mainstream off-road vehicles (B60V front door handle height 1191mm, rear door handle height 1220mm, other off-road vehicle handle heights 1060mm~1154mm). (Q / BAIC C235023-2023 "Ergonomic Design Specification" requires that when the vehicle is unloaded, the distance from the ground for pull-type handles should be 740mm~880mm, and the distance from the ground for pull-out and button-type handles should be 740mm~1160mm; B60V front door handle height 1191mm, rear door handle height 1220mm).

[0019] Among them, the side panel 7 of the test bench is preferably made of Q235 steel plate, the slope platform frame 9 is preferably made of Q235 pipe welded, the adjustable support mechanism is equipped with a sealing surface 4, and the side panel 7 of the test bench is equipped with a side panel stop 2 that matches the sealing surface 4. The side panel stop 2 is a side panel sealing structure that simulates the test vehicle. By fastening the sealing surface 4 and the side panel stop 2 together, the sealing performance of the car door is simulated.

[0020] The sealing surface 4 is rotatably connected to the adjustable support mechanism. When the sealing surface 4 rotates relative to the side wall stop 2, the sealing surface 4 can be fastened into the sealing groove provided on the side wall stop 2. The side wall stop 2 is machined and installed on the side wall plate 7 of the test bench to simulate the side sealing structure of the test vehicle. The side wall stop 2 is fixed on the side wall plate 7 of the test bench by adjusting bolts.

[0021] like Figure 3 and 4 As shown, the adjustable support mechanism includes a hinge column 6, a hinge mechanism 5 connected to the side of the hinge column 6, and several screw mechanisms connected to the hinge column 6. The screw mechanisms are used to adjust the position of the hinge column 6 along the X-axis and Y-axis of the operating platform frame 8, and can be connected and fixed to the sealing surface 4 of different vehicle models' doors. In addition, the Z-axis direction of the hinge column 6 also adopts a telescopic device, such as a screw and nut. By rotating the adjustment dial (1C), the Y-axis position of the hinge column can be adjusted through the screw mechanisms; by rotating the adjustment dial (1D), the X-axis position of the side frame can be adjusted through the screw mechanisms, thus adjusting the installation position and angle of the side frame and the hinge column 6.

[0022] like Figure 5-8 As shown, the sealing surface 4 is connected to the hinge mechanism 5. A door frame 3, which rotates relative to the adjustable support mechanism, is also installed on the adjustable support mechanism, and the sealing surface 4 is positioned between the door frame 3 and the side panel stop 2. The door frame 3 is connected to the hinge mechanism 5. The operating platform frame 8 includes a bracket, a panel installed within the bracket, and a screw rod installed on the panel. A nut is installed on the screw rod, and the panel and bracket are connected in an adjustable manner through the cooperation of the screw rod and the nut. The door sealing strip mounting structure 11 and the door sealing gap 10 between the sealing surface 4 and the side panel stop 2 are also included. The simulated side panel stop 4 is machined and installed on the side panel frame of the test bench, simulating the side panel sealing structure of the test vehicle. Special side panel stops 4 for different vehicle models are custom-made using aluminum alloy, and the mounting points are set in accordance with the test bench base structure. In this embodiment, it is preferably fixed to the side panel of the test bench through 6 adjustable screw connections, and the positions of the side panel points can be adjusted as needed. When simulating the door sealing surface, it is machined and installed on the door frame of the test bench to simulate the door sealing structure of the test vehicle. The special side panel stop for different vehicle models is made of aluminum alloy and the installation point is set in accordance with the test bench base structure.

[0023] In the early conceptual development phase, this design involved customizing the sealing surface and stop frame, and verifying the door system layout parameters and accessory selection in advance to ensure the quality of the initial design. In the later stages, quality was improved by assembling a complete door system to support the verification of perceived quality improvements.

[0024] This utility model introduces a machined structure that can simulate a car door sealing surface and can also mount different car door accessories on the door frame 3. By mounting it on a benchmark car door, collecting opening and closing performance data, and setting development goals, this machined structure, which can simulate a car door sealing surface and mount different car door accessories, increases the versatility of various accessory configurations across different car models. The design provides a tactile evaluation platform for door opening and closing, which, combined with the sound quality evaluation of door opening and closing, establishes a comprehensive evaluation system for the opening and closing quality of the car door system.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
