Therefore, the vehicle window needs to undergo strict durability performance tests before mass production. In order to ensure the standardization and efficiency of the tests, dedicated vehicle window durability test equipment is generally used in the industry to detect the core performance of the vehicle window, such as the lifting cycle and sealing reliability. At present, the traditional vehicle window durability test equipment adopts a fixed installation structure, that is, the vehicle door or window assembly is fixed on a specific test bench, and a single load parameter is set to simulate the stress condition during the lifting process of the vehicle window, so as to complete the cycle test and obtain the durability performance data. Such test equipment has provided a basic support for the quality control of vehicle window products in the early stage of the development of the industry, and is widely used in the research and development and production detection links of various vehicle windows.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] Embodiment one: please refer to Figures 1-7 A durable test mechanism, comprising: a test frame 10; an adjusting plate 20 installed on the test frame 10; A window mounting plate 30 is detachably mounted on the adjusting plate 20, and is used to carry and fix the to-be-tested window and glass lifter; A load assembly 50 is arranged on the adjusting plate 20, and is used to provide lifting load for the window; An inclination adjusting assembly 60 is fixedly arranged on the test frame 10, and an output end of the inclination adjusting assembly 60 is in transmission connection with the adjusting plate 20, and is used to drive the adjusting plate 20 to rotate around the test frame 10 to adjust the inclination angle thereof, so as to simulate different inclination conditions of the vehicle door.

[0031] In the above technical solution, the inclination adjusting assembly 60 and the adjusting plate 20 are in transmission connection, so that the adjusting plate 20 can be flexibly driven to rotate around the test frame 10, the inclination angle of the adjusting plate 20 can be accurately adjusted, and different inclination states of the vehicle door caused by posture changes and road conditions during vehicle driving can be simulated. The load assembly 50 is arranged on the adjusting plate 20, and can provide adaptive load force for the window lifting in cooperation with the inclination angle adjustment, so as to realize all-round simulation of the window lifting process in combination with the real inclination condition, effectively reduce the difference between the test environment and the real use scene, improve the consistency between the test result and the actual durability of the window, and provide accurate data support for the design optimization of the window product. The window mounting plate 30 is detachably connected with the adjusting plate 20, so that the mechanism can be quickly adapted to different models and specifications of the to-be-tested window and glass lifter, and a special test bench does not need to be customized for different test objects, and the universality of the equipment is improved.

[0032] Specifically, the adjusting plate 20 is used as an intermediate bearing and transmission carrier, on one hand, is in transmission connection with the inclination adjusting assembly 60, receives the driving force output by the inclination adjusting assembly 60, and is adjusted in inclination angle, and on the other hand, is detachably connected with the window mounting plate 30, and provides a mounting carrier for the to-be-tested window and glass lifter. The detachable design of the window mounting plate 30 follows the modular design principle, and different test objects can be adapted by replacing or adjusting the window mounting plate 30, and the adaptability of the equipment is improved. The load assembly 50 is arranged on the adjusting plate 20, and can adjust the load application direction and size synchronously with the change of the inclination angle of the adjusting plate 20, so as to ensure that the window can be provided with lifting load in accordance with the real use scene in different inclination conditions. The inclination adjusting assembly 60 is fixedly arranged on the test frame 10, and is in transmission connection with the adjusting plate 20 through the output end, so as to stably drive the inclination angle of the adjusting plate 20.

[0033] In one embodiment, the test frame 10 comprises a back plate 101, the adjusting plate 20 is installed on the back plate 101, the back plate 101 is fixed with a positioning pin 102 on the side facing the adjusting plate 20, the adjusting plate 20 is provided with an adjusting hole 202 corresponding to the position of the positioning pin 102, the positioning pin 102 is arranged in the adjusting hole 202, the adjusting hole 202 is arc-shaped, the extension track of the adjusting hole 202 matches the rotation track of the adjusting plate 20, so that the movement track of the adjusting plate 20 is limited and the adjusting plate 20 is guided to move around the positioning pin 102 by the sliding fit of the positioning pin 102 and the arc-shaped adjusting hole 202, so as to adjust the inclination angle of the adjusting plate 20.

[0034] In the above technical solution, the adjusting hole 202 is designed as an arc shape matching the rotation track of the adjusting plate 20, so that the center of the arc-shaped adjusting hole 202 is consistent with the rotation center of the adjusting plate 20. When the driving force of the inclination adjusting assembly 60 drives the adjusting plate 20 to move, the positioning pin 102 and the arc-shaped adjusting hole 202 form a sliding fit pair, the positioning pin 102 is used to limit the rotation of the adjusting plate 20 along the extension direction of the arc-shaped adjusting hole 202, and the adjusting plate 20 is guided to complete the adjustment of the inclination angle. At the same time, the guide limiting structure cooperates with the intermediate carrier function of the adjusting plate 20. When the adjusting plate 20 rotates stably under the constraint of the positioning pin 102 and the arc-shaped adjusting hole 202, the vehicle window mounting plate 30, the vehicle window to be tested and the load assembly 50 installed thereon are synchronously moved, so that the load assembly 50 can adjust the direction and size of the load application synchronously with the inclination angle of the adjusting plate 20. In combination with the precise driving of the inclination adjusting assembly 60, the inclination angle of the adjusting plate 20 can be controlled and adjusted, and finally a stable and real use scene matching vehicle window inclination test working condition is constructed.

[0035] In one embodiment, the side of the adjusting plate 20 is provided with a plurality of limiting pins 203, and the side of the vehicle window mounting plate 30 is provided with a plurality of mounting holes 301, and the limiting pins 203 are installed in the corresponding mounting holes 301.

[0036] In one embodiment, the load assembly 50 comprises a mounting seat 501 connected with the driving assembly 40, a rotating arm 503 installed on the mounting seat 501, a resistance block 504 installed on one end of the rotating arm 503, the resistance block 504 being in contact with the vehicle window, the side of the mounting seat 501 being provided with a mounting groove, the rotating arm 503 being rotatably connected in the mounting groove, one end of the rotating arm 503 being provided with an elastic member 505, and the end of the elastic member 505 away from the rotating arm 503 being installed on the mounting seat 501.

[0037] In the technical scheme, the elastic member 505 is a spring or an elastic block; the mounting groove provided on the mounting base 501 provides a rotating fulcrum for the rotating arm 503, so that the rotating arm 503 can rotate flexibly around the hinge point in the mounting groove, forming a lever force structure; the resistance block 504 at one end of the rotating arm 503 is used for directly contacting the vehicle window to be tested, and the elastic member 505 connected at the other end of the rotating arm 503 is used as an output source of the load force; when the vehicle window is lifted, the resistance block 504 is driven to move synchronously, and in turn drives the rotating arm 503 to rotate around the hinge point and generates a pulling or compression action on the elastic member 505; the reverse elastic force generated by the deformation of the elastic member 505 is used as a simulated load, so as to reproduce the dynamic resistance change of the sealing strip in the real use process with the lifting of the vehicle window; at the same time, the structure design can flexibly adjust the size of the load force by replacing the elastic member 505 with different elastic coefficients, so as to adapt to the needs of different test working conditions; and the load assembly 50 is assembled on the adjusting plate 20, so that the posture of the load assembly 50 can be adjusted synchronously with the inclination of the adjusting plate 20, so as to ensure that the resistance block 504 is always effectively attached to the vehicle window, and the precise application of the load force in the inclined working condition is realized; and the load assembly 50 cooperates with other components of the overall test mechanism to build a vehicle window test environment close to the real one.

[0038] In one embodiment, the driving assembly 40 comprises a fixed plate 401 mounted on the adjusting plate 20, a second guide rail 403 mounted on the fixed plate 401, a second sliding block 502 mounted on one side of the mounting base 501, the second sliding block 502 being slidably connected to the second guide rail 403, two driving wheels 405 mounted on the fixed plate 401, a belt 406 mounted on the two driving wheels 405, the mounting base 501 being mounted on the belt 406, and a servo motor 404 mounted on the fixed plate 401, the output shaft of the servo motor 404 being connected to the driving wheels 405.

[0039] Specifically, the second guide rail 403 and the second sliding block 502 on the side of the mounting base 501 form a sliding guide pair. The limiting effect of the guide rail restricts the mounting base 501 to move along the preset straight track in a reciprocating manner only, so as to avoid lateral deviation during movement. The servo motor 404 serves as a power output source. The output shaft of the servo motor 404 is connected with the driving wheel 405, so that the rotating power of the motor can be transmitted to the driving wheel 405, and then the belt 406 sleeved on the two driving wheels 405 is driven to move in a circulating and reciprocating manner. Since the mounting base 501 is fixedly assembled on the belt 406, the circulating movement of the belt 406 can be converted into the linear reciprocating movement of the mounting base 501 synchronously, so as to drive the load assembly 50 mounted on the mounting base 501 to move synchronously, thereby achieving dynamic load simulation on the window lifting process. The precise control characteristics of the servo motor 404 can be flexibly adjusted in speed and direction according to test requirements, so as to change the movement speed and direction of the load assembly 50, adapt to the lifting test working conditions of different windows, and ensure that the load assembly 50 remains stable during long-time reciprocating movement.

[0040] In a preferred embodiment, one side of the adjusting plate 20 is provided with a first guide rail 201, and one side of the fixed plate 401 is provided with a first sliding block 402 which is slidingly connected to the first guide rail 201.

[0041] In a preferred embodiment, the inclination adjusting assembly 60 comprises an angle plate 602 mounted on the back plate 101, a threaded sleeve 603 mounted on the angle plate 602, and a screw rod 604 threadedly connected in the threaded sleeve 603. One end of the screw rod 604 is provided with a top head which is in contact with the bottom of the adjusting plate 20. The other end of the screw rod 604 is provided with a handle 605. The back plate 101 is provided with an assembly plate 601, and the angle plate 602 is mounted on the assembly plate 601.

[0042] Specifically, the fixed installation of the angle plate 602 is realized by the assembly plate 601, which provides a stable assembly reference for the threaded sleeve 603 and ensures that the position of the threaded sleeve 603 does not deviate during adjustment; the design of the angle plate 602 is used to adapt the installation angle and position of the threaded sleeve 603, so that the screw rod 604 can realize linear motion in the preset direction; the screw rod 604 and the threaded sleeve 603 constitute a threaded pair, which converts the rotary motion of the handle 605 into the axial linear motion of the screw rod 604 by utilizing the helical transmission characteristics of the thread; when the handle 605 is rotated, the screw rod 604 advances and retreats along its own axis direction under the constraint of the threaded sleeve 603; the top of one end of the screw rod 604 directly contacts the bottom of the adjusting plate 20, and the linear feeding motion of the screw rod 604 can apply a pushing force to the bottom of the adjusting plate 20 through the top, which pushes the adjusting plate 20 to rotate around the rotating fulcrum formed by the positioning pin 102 and the arc-shaped adjusting hole 202, and then realizes the adjustment of the inclination angle of the adjusting plate 20; the self-locking characteristic of the threaded transmission can make the screw rod 604 stay and fix at any position, which ensures that the adjusting plate 20 can be stably positioned after being adjusted to the target inclination angle, and avoids the change of the angle during the test.
