Description

Technical Field

[0001] This disclosure relates to the field of vehicle performance testing technology, and more specifically, to a door switch durability testing device. Background Technology

[0002] Automotive durability testing is finely categorized. Door quality testing encompasses multiple methods, including pressure-based collision simulation, rain sealing tests, and mechanical opening and closing durability tests, ensuring that every door can withstand impacts, insulate against noise, resist corrosion, and be durable, comprehensively protecting driving safety and comfort. As the main entrance and protective component of a vehicle, the quality and reliability of car doors directly impact the overall vehicle performance. Therefore, mechanical opening and closing durability testing requires rigorous evaluation of the strength, sealing, and fatigue resistance of car doors and hoods. Fatigue resistance testing simulates the repeated opening and closing of doors and hoods to verify their durability over long-term use. Door opening and closing durability testing verifies the reliability of the door system and its components by using mechanical devices to simulate frequent door opening and closing movements.

[0003] In related technologies, door opening and closing durability tests are conducted by pushing and pulling a cylinder. The cylinder end is connected to the door handle by a rope, resulting in poor controllability of movement precision and force, making it difficult to handle the opening and closing tests of concealed door handles. Utility Model Content

[0004] The purpose of this disclosure is to provide a door opening and closing durability testing device to at least partially solve the problems existing in the related art.

[0005] To achieve the above objectives, this disclosure provides a vehicle door switch durability testing device. The vehicle door is equipped with a concealed door handle, which has a pressing portion and a pop-out portion. The concealed door handle is configured such that when the pressing portion is pressed into the door panel, the pop-out portion extends out of the door panel. The vehicle door switch durability testing device includes: support; A pneumatic gripper, mounted on the bracket, is used to clamp the pop-out portion to open the vehicle door; A pressing wheel, mounted on the bracket, is used to push the pressing part to cause the pop-out part to extend beyond the door panel. The pressing wheel and the pneumatic gripper are arranged side-by-side at intervals. A drive mechanism, the output end of which is connected to the bracket, is used to drive the bracket to move.

[0006] In some possible implementations, the pressing wheel is mounted to the bracket via a connecting frame, the connecting frame including a connecting frame body detachably connected to the bracket and a support arm for mounting the pressing wheel, the support arm being arranged at an angle relative to the pneumatic gripper. There is a gap between the pneumatic gripper and the pressing wheel; to reduce material consumption, the support arm is angled away from the pneumatic gripper, thus reducing the length of the connecting frame body.

[0007] In some possible implementations, the support arm is tilted at 10° to 45° relative to the pneumatic gripper.

[0008] In some possible implementations, the press wheel is rotatably mounted at the end of the support arm. This rotatability ensures reduced friction at the contact point with the concealed door handle during door opening, preventing scratches to the paint.

[0009] In some possible implementations, the pressing roller is made of rubber. The rubber material helps prevent scratches on the paint and avoids contact between the metal or hard plastic mounting structure and the paint.

[0010] In some possible implementations, the pneumatic gripper includes an air guide block mounted on the bracket and multiple flexible individual fingers. The air guide block is used to connect to an air source and communicates with the air chambers of the flexible individual fingers. Gas is supplied to the multiple flexible individual fingers through the air guide block, causing the flexible individual fingers to bend and deform, thereby achieving the gripping of the concealed door handle.

[0011] In some possible implementations, the bracket is constructed as a frame structure with mounting holes, and the sidewall of the air guide block is provided with a mounting groove, the air guide block passing through the mounting hole so that the mounting groove is engaged with the inner sidewall of the bracket forming the mounting hole.

[0012] In some possible implementations, the door switch durability testing device further includes a connecting plate and a plurality of connecting posts. The connecting plate is used to connect the drive mechanism, and the plurality of connecting posts are vertically connected between the connecting plate and the bracket, and the plurality of connecting posts are evenly arranged along the circumference of the connecting plate. By setting the connecting posts, the connecting frame and the air guide block can be avoided, allowing the bracket to be connected to the drive mechanism.

[0013] In some possible implementations, the pneumatic gripper includes two of the flexible single fingers. The pneumatic gripper can flexibly select the length and number of flexible single fingers according to the size and shape of the concealed door handle, thereby ensuring effective and reliable gripping without damaging the concealed door handle. It is simple to control and easy to operate.

[0014] In some possible implementations, the flexible single finger is made of polyurethane. Polyurethane material has high mechanical strength to accommodate gripping concealed door handles, and also possesses good elasticity and flexibility, with a smooth surface to prevent scratching the vehicle paint.

[0015] The above technical solution controls the position and angle of the support frame via a drive mechanism. A pressing wheel and a pneumatic gripper are mounted on the support frame, working in tandem. The pressing wheel pushes the pressing part of the concealed door handle into the door, while the pneumatic gripper clamps the pop-out part to open the door. To close, the pneumatic gripper pushes the door back in, thus repeatedly meeting the requirements of the door opening and closing test. This door opening and closing durability testing device possesses sufficient strength and will not scratch the paint, ensuring stable operation.

[0016] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the outline of the corresponding component itself. In this disclosure, when the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] Concealed door handles are commonly used in electric vehicles. During durability testing, the door handle needs to be pressed in a specific area to pop out the other end, allowing manual opening and closing of the door, simulating the repeated opening and closing of the door. In related technologies, door opening and closing durability tests are conducted using a cylinder push-pull mechanism. The cylinder end is connected to the door handle via a rope, resulting in poor precision and controllability of force, making it unsuitable for testing concealed door handles.

[0022] To solve the above problems, refer to Figure 1 , Figure 2 This disclosure provides a vehicle door opening and closing durability testing device. The vehicle door has a concealed door handle, which has a pressing part and a pop-out part. The concealed door handle is elongated, with the pressing part and the pop-out part arranged side by side. The concealed door handle is configured such that when the pressing part is pressed into the door panel, the pop-out part extends out of the door panel, allowing the door to be opened by pulling the pop-out part. The vehicle door opening and closing durability testing device may include a bracket 1, a pneumatic gripper 2, a pressing wheel 3, and a drive mechanism. The pneumatic gripper 2 is mounted on the bracket 1 and is used to clamp the pop-out part to open the door. The pressing wheel 3 is mounted on the bracket 1 and is used to push the pressing part so that the pop-out part extends out of the door panel. The pressing wheel 3 and the pneumatic gripper 2 are arranged side by side at intervals. The output end of the drive mechanism is connected to the bracket 1 and is used to drive the bracket 1 to move. Specifically, the drive mechanism can be a robot, which adjusts the angle of the robot arm to drive the bracket 1 to move, so that the pressing wheel 3 performs a pressing action. When the car door needs to be opened, the drive mechanism drives the bracket 1 to move closer to the car door so that the pressing wheel 3 abuts against the pressing part of the hidden door handle, thereby pushing the pressing part to make the pop-out part pop out of the car door panel. At this time, the pneumatic gripper 2 clamps the pop-out part, and the drive mechanism drives the bracket 1 to move away from the car door, and the car door is opened. The pneumatic gripper 2 releases the pop-out part, and the drive mechanism drives the bracket 1 to move closer to the car door so that the end of the pneumatic gripper 2 pushes the car door to close it. This process can be repeated to simulate the repeated opening and closing of the car door.

[0023] The above technical solution controls the position and angle of the support frame via a drive mechanism. A pressing wheel and a pneumatic gripper are mounted on the support frame, working in tandem. The pressing wheel pushes the pressing part of the concealed door handle into the door, while the pneumatic gripper clamps the pop-out part to open the door. To close, the pneumatic gripper pushes the door back in, thus repeatedly meeting the requirements of the door opening and closing test. This door opening and closing durability testing device possesses sufficient strength and will not scratch the paint, ensuring stable operation.

[0024] As an exemplary embodiment of this disclosure, reference is made to Figure 1The pressing wheel 3 is mounted to the bracket 1 via a connecting frame 4. The connecting frame 4 may include a connecting frame body 41 detachably connected to the bracket 1 and a support arm 42 for mounting the pressing wheel 3. The support arm 42 is arranged at an angle relative to the pneumatic gripper 2. There is a gap between the pneumatic gripper 2 and the pressing wheel 3. To reduce material consumption, the support arm 42 is arranged at an angle away from the pneumatic gripper 2, which reduces the length of the connecting frame body 41. Specifically, the connecting frame body 41 may be constructed as two support plates respectively mounted on the front and rear sides of the bracket 1. The two support plates are connected by fasteners such as bolts. The support arm 42 may be integrally formed with the connecting frame body 41.

[0025] Furthermore, referring to Figure 1 The support arm 42 can be tilted relative to the pneumatic gripper 2 at an angle of 10° to 45°, specifically 20° or 30°. The tilt angle of the support arm 42 can be adaptively designed according to actual needs, and this disclosure does not impose any limitations on it.

[0026] Among them, reference Figure 1 , Figure 2 The press wheel 3 is rotatably mounted at the end of the support arm 42. The rotatability of the press wheel 3 ensures reduced friction at the contact point with the concealed door handle during door opening, preventing scratches to the paint. Furthermore, the press wheel 3 can be replaced after wear.

[0027] Furthermore, the material of the pressing roller 3 can be rubber. The rubber material can prevent scratches on the car paint and avoid contact between the metal or hard plastic mounting structure and the car paint. Specifically, a high-elasticity, low-hardness rubber can be selected, preferably with a hardness range of 25°A to 35°A. This hardness range ensures that the hardness of the roller is much lower than that of the car paint. If compression occurs, the roller itself will deform rather than penetrate the paint surface.

[0028] In embodiments of this disclosure, reference is made to Figure 1 , Figure 2 The pneumatic gripper 2 may include an air guide block 21 mounted on a bracket 1 and multiple flexible single fingers 22. The air guide block 21 is used to connect to an air source and communicates with the air chambers of the flexible single fingers 22. Gas is supplied to the multiple flexible single fingers 22 through the air guide block 21, causing the flexible single fingers 22 to bend and deform, thereby achieving the gripping of the concealed door handle.

[0029] In some embodiments, refer to Figure 1 The bracket 1 can be constructed as a frame structure with mounting holes. The side wall of the air guide block 21 is provided with a mounting groove. The air guide block 21 passes through the mounting hole so that the mounting groove is locked onto the inner side wall of the bracket 1 forming the mounting hole. This disclosure does not limit the installation method of the air guide block 21. In addition to snap-fit, the air guide block 21 can also be connected by bolts or interference fit to the bracket 1.

[0030] According to some embodiments, refer to Figure 1 , Figure 2 The door opening and closing durability testing device may also include a connecting plate 5 and multiple connecting posts 6. The connecting plate 5 is used to connect the drive mechanism, and the multiple connecting posts 6 are vertically connected between the connecting plate 5 and the bracket 1. The multiple connecting posts 6 can be evenly arranged along the circumference of the connecting plate 5. By setting the connecting posts 6, the connecting frame 4 and the air guide block 21 can be avoided, allowing the bracket 1 to be connected to the drive mechanism.

[0031] In embodiments of this disclosure, reference is made to Figure 1 , Figure 2 The pneumatic gripper 2 may include two flexible single fingers 22. The pneumatic gripper 2 can flexibly select the length and number of flexible single fingers 22 according to the size and shape of the concealed door handle, thereby ensuring effective and reliable gripping without damaging the concealed door handle. It is simple to control and easy to operate.

[0032] Among them, the flexible single finger 22 can be made of polyurethane. Polyurethane material has high mechanical strength to adapt to gripping concealed door handles, and has good elasticity and flexibility, with a smooth surface to prevent scratching the car paint.

[0033] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0034] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0035] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
