Description

Technical Field

[0001] This utility model relates to the technical field of durability testing devices, specifically, to a durability testing device for windshield wiper manufacturing. Background Technology

[0002] Durability testing devices for windshield wiper production are key equipment used to test the wear resistance and lifespan of windshield wipers. They mainly test the durability of wipers by simulating their working conditions in actual use. Generally, the test parameters are set by the control system, and the motion mechanism drives the reciprocating motion of the wiper through the linkage mechanism via a motor. The load simulation device simulates the working load under different conditions, and some high-end devices are also equipped with an environmental simulation system to simulate the usage environment under different climatic conditions.

[0003] Traditional durability testing equipment used in wiper manufacturing typically involves fixing the wiper to the output shaft of the test mechanism using bolts. The reciprocating motion of the mechanism drives the wiper to swing. After the test, this method requires tools to remove and reinstall the wiper, resulting in relatively low testing efficiency.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a durability testing device for windshield wiper production, including a housing 1. A sprayer 11 is fixedly connected to the inner side of the upper end of the housing 1, and a water tank 12 is fixedly connected to the upper end of the sprayer 11 through the housing 1. A tester 13 is fixedly connected to the inner side of one end of the housing 1, and a wiper blade 14 is provided on the output shaft of the motion mechanism inside the lower end of the tester 13. A cabinet door 15 is rotatably connected to the outer side of the housing 1 away from the tester 13. An installation assembly 2 is provided at the lower end of the wiper blade 14, and the installation assembly 2 includes an internally threaded cylinder 21 fixedly connected to the lower end of the wiper blade 14. The internally threaded cylinder 21 is located away from the wiper blade. One end of the wiper blade 14 is internally threaded with an external threaded rod 22, and the end of the external threaded rod 22 away from the internal threaded cylinder 21 is fixedly connected to the output shaft of the lower motion mechanism of the tester 13. One end of the internal threaded cylinder 21 is provided with a locking component 3, and the end of the locking component 3 away from the internal threaded cylinder 21 is provided with a telescopic component 4. One end of the telescopic component 4 is provided with a spring component 5, and the inner side of the middle of the wiper blade 14 is provided with a blower component 6. The inner sides of both ends of the outer casing 1 are provided with filter components 7. By using the mounting component 2 and the locking component 3, the efficiency of disassembly and assembly can be effectively improved when replacing the wiper blade, thereby improving the convenience of testing.

[0020] like Figure 2 As shown, the locking assembly 3 includes a locking plate 31 inserted into the inner side of one end of the internal threaded cylinder 21, and a pull block 32 fixedly connected to the outer side of the end of the locking plate 31 away from the internal threaded cylinder 21. When the internal threaded cylinder 21 is screwed in, it squeezes the locking plate 31, thereby moving the locking plate 31 to squeeze the insertion rod 41, etc. When the internal threaded cylinder 21 is installed, the elastic potential energy of the spring 52 pushes the collar 51, so that it drives the locking plate 31 to be inserted into the internal threaded cylinder 21 through the insertion rod 41 to fix the internal threaded cylinder 21.

[0021] like Figure 3 As shown, the telescopic assembly 4 includes a rod 41 fixedly connected to the side of the clamping plate 31 away from the internal threaded cylinder 21, and a protective cover 42 is sleeved on the outer side of the end of the rod 41 away from the clamping plate 31. The end of the protective cover 42 near the tester 13 is fixedly connected to the tester 13, and a sleeve 43 is fixedly connected to the inner side of the end of the protective cover 42 away from the rod 41. The end of the sleeve 43 near the rod 41 is sleeved on the outer side of the rod 41. When the clamping plate 31 moves, it squeezes the rod 41. After the rod 41 is pushed, it moves and is inserted into the sleeve 43 under the protection of the protective cover 42. When the rod 41 moves, it synchronously drives the collar 51 to compress the spring 52.

[0022] like Figure 3 As shown, the elastic component 5 includes a collar 51 fixedly connected to the outer side of the insertion rod 41 near the sleeve 43, and a spring 52 fixedly connected to one side of the outer end of the collar 51. The end of the spring 52 away from the collar 51 is fixedly connected to the protective cover 42. The elastic potential energy of the spring 52 pushes the collar 51, so that it drives the clamping plate 31 through the insertion rod 41 to be inserted into the internal threaded cylinder 21 to fix the internal threaded cylinder 21.

[0023] like Figure 1 As shown, the blower assembly 6 includes a fixed bracket 61 fixedly connected to the inner side of the middle of the wiper blade 14, and a mounting plate 62 fixedly connected to the inner side of the middle of the fixed bracket 61. A turbine fan 63 is fixedly connected to the outer side of the middle of the mounting plate 62, and one end of the turbine fan 63 is electrically connected to a housing 64. The housing 64 is fixedly connected to the fixed bracket 61 on the side near the fixed bracket 61. When the housing 64 is started, the turbine fan 63 is turned on, and the turbine fan 63 blows air into the tester 13 and the wiper blade 14 through the holes and slots at the cabinet door 15.

[0024] like Figure 4 As shown, the mounting bracket 61 has a slot in the cabinet door 15 near the cabinet door 15. The slot in the cabinet door 15 allows outside air to enter the outer shell 1.

[0025] like Figure 1 As shown, the filter assembly 7 includes filter screens 71 inserted inside both ends of the housing 1, and fastening bolts 72 are threaded on both ends of the filter screens 71. The fastening bolts 72 are threaded on one end of the housing 1. The filter screens 71 can be removed by unscrewing the fastening bolts 72 so that they can be cleaned.

[0026] Working principle: After testing the wiper blade 14, when replacing it, first open the cabinet door 15, then pull the pull block 32 to move the clamping plate 31, thereby allowing the clamping plate 31 to move and press the insert rod 41. After being pushed, the insert rod 41 moves and is inserted into the sleeve 43 under the protection of the cover 42. When the insert rod 41 moves, it simultaneously drives the collar 51 to compress the spring 52. After the clamping plate 31 is pulled out of the inner threaded cylinder 21, the inner threaded cylinder 21 can be screwed to disengage it from the outer threaded rod 22 to remove the wiper blade 14. Then, the replaced wiper blade 14 is screwed onto the outside of the outer threaded rod 22 along with the inner threaded cylinder 21. When the inner threaded cylinder 21 is screwed in, it presses the clamping plate 31, thereby allowing... The clamping plate 31 moves to press the insertion rod 41, etc. After the internal threaded cylinder 21 is installed, the elastic potential energy of the spring 52 pushes the collar 51, so that it drives the clamping plate 31 to be inserted into the internal threaded cylinder 21 through the insertion rod 41 to fix the internal threaded cylinder 21. Then close the cabinet door 15, and start the sprayer 11 to spray water on the tester 13 and the wiper blade 14. At the same time, start the machine box 64 to make the turbine fan 63 run, so that the turbine fan 63 blows air into the tester 13 and the wiper blade 14 through the holes and slots at the cabinet door 15. After the airflow enters the outer shell 1 and blows onto the tester 13 and the wiper blade 14, it is discharged from the filter screen 71 at both ends of the outer shell 1.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
