Detailed Implementation

[0026] 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, and 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 protection scope of the present utility model.

[0027] Figure 1 This shows a first structural schematic diagram of the experimental device in this utility model. Figure 2 This shows a second structural schematic diagram of the experimental device in this utility model. Figure 3 A schematic diagram of the impact plate in this invention is shown. Figure 4A schematic diagram of the product bracket in this utility model is shown. The test device for simulating the impact durability of a car door includes: a fixed bracket 1 and a door panel 2; the fixed bracket 1 includes: a base 11 and an impact plate 12, the impact plate 12 is fixedly mounted on the base 11, the impact plate 12 has a door frame 121 that cooperates with the door panel 2, and multiple rubber strips 122 are provided on the edge of the door frame 121; one side of the impact plate 12 has a hinge portion 123, and the door panel 2 is hinged to the impact plate 12 based on the hinge portion 123. In this embodiment, two rubber strips 122 are provided on the edge of the door frame 121, and the two rubber strips 122 are symmetrically distributed on the edge of the door frame 121. When the rubber strips 122 are impacted by the door panel 2, the rubber material inside them will deform. This deformation process will absorb a large amount of impact energy, thereby playing a buffering role, reducing the vibration between the door panel 2 and the impact plate 12, avoiding wear after repeated impacts between the door and the fixed bracket 1, and helping to extend the service life of the test device. Secondly, the rubber strip 122 is attached to the edge of the door frame 121. When the door panel 2 collides with the impact plate 12, the rubber strip 122 deforms, increasing the contact area with the door panel 2, thereby increasing the friction between the door panel 2 and the rubber strip 122. This prevents the door panel 2 from shaking in the door frame 121 and repeatedly colliding with the door frame 121 after the door panel 2 collides with the impact plate 12, thus avoiding damage to the door panel 2 or the door frame 121 due to impact. This helps to reduce the damage to the test device from impact and vibration and extend the service life of the test device.

[0028] Furthermore, the hinge portion 123 includes a connecting plate 1231 and a hinge 1232. The fixed end of the hinge 1232 is fixed to the connecting plate 1231, and the connecting end of the hinge 1232 is connected to the impact plate 12. In this embodiment, the hinge portion 123 has two connecting plates 1231 and two hinges 1232. One hinge 1232 is correspondingly mounted on one connecting plate 1231, and the two hinges 1232 are hinged to the door panel 2 from two different positions, which aims to provide stable support for the door panel 2 and smooth opening and closing actions, ensuring that the door panel 2 can smoothly impact the impact plate 12.

[0029] It should be noted that the hinge 1232 is the original car door hinge that is matched with the door panel 2, which can better simulate the real use environment and test the durability of the original car door hinge.

[0030] Furthermore, a product bracket 21 is provided on the door panel 2, and the product bracket 21 is detachably installed in the middle area of ​​the door panel 2. The position of the product bracket 21 on the door panel 2 can be adjusted according to the usage to test the stability of the product bracket 21 in different positions. Moreover, the product bracket 21 can be changed according to the object to be tested, that is, each product bracket 21 corresponds to a different test object, ensuring that the test lamp can be fixed on the corresponding product bracket 21.

[0031] Furthermore, the product bracket 21 is provided with a plurality of first fixing holes 211, which are distributed sequentially along the edge of the product bracket 21. In this embodiment, the product bracket 21 is provided with nine first fixing holes 211, each of which is distributed sequentially along the edge of the product bracket 21. The nine first fixing holes 211 provide more support points for fixing the product bracket 21 to the door panel 2, which can more effectively distribute the force and reduce the situation of excessive force on a single point, thereby improving the overall stability. In addition, the nine first fixing holes 211 can significantly reduce the shaking of the product bracket 21 under force, making the structure more stable.

[0032] Furthermore, the product bracket 21 is provided with a mounting slot 212, which is integrally formed with the product bracket 21. The mounting slot 212 is used to fix the corresponding lamp onto the product bracket 21, and the mounting slot 212 includes two buckles. When the corresponding lamp is fixed to the mounting slot 212, the two buckles hold the lamp in place, preventing the lamp from falling off the mounting slot 212 when the door panel 2 hits the corresponding impact plate 12, thus ensuring the stability of the lamp fixed to the mounting slot 212. The integral formation of the mounting slot 212 and the product bracket 21 means that they are formed simultaneously during the manufacturing process, without additional connecting parts or assembly steps, which improves the overall strength and stability of the product bracket 21.

[0033] Furthermore, the product bracket 21 is made of polypropylene (PP). Polypropylene (PP) has good strength, rigidity, and hardness, making the bracket less prone to deformation or damage when subjected to external forces, thus ensuring the stability and safety of the structure. Polypropylene (PP) material also has good aging resistance, resisting the erosion of factors such as ultraviolet rays and oxidation in the natural environment, thereby extending the service life of the bracket.

[0034] Furthermore, a handle 22 is also provided on the door panel 2. The fixed end of the handle 22 is fixedly connected to the door panel 2, and a ring 221 is provided at the connecting end of the handle 22. In this embodiment, the handle 22 is located on the side of the door panel 2 away from the hinge. When the handle 22 is subjected to force, it drives the entire door panel 2 to move, achieving the effect of simulating opening or closing the door. When an external force is applied to the ring 221, the ring 221 can evenly transmit the pressure to the entire ring 221. The pressure is distributed across the entire contact surface of the ring 221, making the pressure distribution on the ring 221 more uniform. This ensures that the handle 22 can maintain its shape even under large pulling force, extending the service life of the handle.

[0035] Furthermore, the testing device also includes a drive mechanism connected to the door panel 2 via the handle 22. The drive mechanism either causes the door panel 2 to impact the impact plate 12 or moves the door panel 2 away from the impact plate 12. The output end of the drive mechanism has a pull rod connected to the handle 22. The drive mechanism can drive the door panel 2 to impact the impact plate 12, simulating the lateral impact when the vehicle door is closed, accurately reflecting the durability performance when closing the door in actual use. The drive mechanism can also drive the door panel 2 away from the impact plate 12, simulating the lateral impact when opening the door, accurately reflecting the durability performance when opening the door in actual use.

[0036] It should be noted that the drive mechanism can automatically perform door impact tests according to preset parameters and programs, and each preset parameter corresponds to various situations, simulating the lateral impact when the vehicle door is opened and closed, which can more accurately reflect the durability performance in actual use.

[0037] Furthermore, the base 11 is provided with a plurality of second fixing holes 111, each of which is provided with a fixing part. The impact plate 12 is fixed to the base 11 based on the plurality of fixing parts. In this embodiment, the base 11 is provided with twelve second fixing holes 111, each of which is provided with a corresponding fixing part, which can be a screw or a bolt. The impact plate 12 is firmly fixed to the base 11 by these fixing parts. The twelve second fixing holes 111 strengthen the connection between the impact plate 12 and the base 11 from different positions, avoiding structural damage caused by excessive force on a single point of the impact plate 12 when subjected to impact force. This helps to evenly distribute the force to each fixing point, effectively reducing the deformation of the impact plate 12 under stress, maintaining its original shape and size, and extending the service life of the testing device.

[0038] Furthermore, the impact plate 12 is provided with reinforcing ribs 13, which are located at the edge of the door frame 121. One side of the reinforcing rib 13 is fixedly connected to the impact plate 12, and the other side is fixedly connected to the base 11. In this embodiment, the impact plate 12 is provided with two reinforcing ribs 13, which are located on both sides of the door frame 121. The two reinforcing ribs 13 can significantly increase the cross-sectional moment of inertia of the structure, thereby improving its stiffness and strength. When the impact plate 12 is subjected to external forces, it can better resist deformation and damage, effectively reducing the degree of product deformation and ensuring the shape stability and service life of the product. Secondly, the reinforcing ribs 13 can also distribute concentrated loads to a larger area, thereby reducing the local stress level and avoiding structural damage caused by stress concentration, which is beneficial to extending the service life of the testing device.

[0039] In summary, this utility model increases the contact area between the door panel and the door frame by setting a rubber strip on the door frame, thereby increasing the friction between the door panel and the rubber strip. This prevents repeated collisions between the door panel and the door frame after the door panel collides with the impact plate, which would otherwise damage the door panel or door frame due to impact. This helps to reduce the impact and vibration damage to the testing device and extend the service life of the testing device.
