DETAILED DESCRIPTION

[0030] The following will be described in detail with reference to the accompanying drawings. Figures 1-3 The present application will be further described in detail.

[0031] The embodiment of the present application discloses a wiper heavy rainfall test device, referring to Figure 1 , including wiper 4 fixing tool 1, glass fixing tool 2 and watering tool 3, wherein the glass fixing tool 2 is connected with the wiper fixing tool 1, the watering tool 3 is installed on the glass fixing tool 2, through the cooperation of the three, the wiper 4 can be tested by heavy rainfall test, and the performance of the wiper 4 under different rainfall intensity is tested.

[0032] Referring to Figure 1The spraying assembly 32 comprises a water pipe 321, a spraying head 322, a water pump 324 and a pressure regulating valve 323. The water pipe 321 is arranged on the truss 312, and can be made of PVC pipe or rubber pipe, etc. The spraying head 322 is arranged towards the workbench 21, and is used to spray water onto the glass 5 on the workbench 21 to simulate the rainfall environment. The water pump 324 provides power for the water flow, and the pressure regulating valve 323 can regulate the water pressure, thereby controlling the rainfall amount. When it is required to simulate rainfall of different intensities, the water pressure in the water pipe 321 can be changed by adjusting the pressure regulating valve 323, and then the water spraying speed and amount of the spraying head 322 are changed. When it is required to simulate heavy rainfall, the opening of the pressure regulating valve 323 is increased to increase the water pressure in the water pipe 321, and the spraying head 322 sprays more water in a more rapid manner; when it is required to simulate light rainfall, the opening of the pressure regulating valve 323 is decreased. Specifically, the combination logic of the components of the spraying assembly 32 is that the water pump 324 delivers water into the water pipe 321, the water pipe 321 guides the water to the spraying head 322, and the pressure regulating valve 323 controls the water pressure in the water pipe 321. Through this combination, the water spraying condition of the spraying head 322 can be accurately controlled according to the test requirements, and rainfall environments of different intensities are simulated to provide real test conditions for the wiper 4.

[0033] With reference to Figure 1 The wiper fixing tool 1 comprises a connecting seat 11 and a fixing plate 12, and the fixing plate 12 is connected with the glass fixing tool 2 through the connecting seat 11. The connecting seat 11 is provided with a waist-shaped hole 111, which is used to adjust the installation position of the connecting seat 11 within a certain range, thereby adapting to the installation requirements of wipers 4 of different models. The fixing plate 12 is provided with an opening 121, which can be used to install components such as the wiper driving device 6. Openings of different shapes can be adapted to different types of wipers 4.

[0034] The test device further comprises a counter 7, which is linked with the wiper driving device 6 of the wiper fixing tool 1. The counter 7 can record the wiping times of the wiper 4 to provide data support for the fatigue test. When the wiper 4 performs wiping work under different rainfall intensities, the counter 7 accurately records the cycle times of the wiping, which facilitates the subsequent evaluation of the performance of the wiper 4.

[0035] With reference to Figure 1 and Figure 2The watering tool 3 comprises a support assembly 31 and a spraying assembly 32. The support assembly 31 comprises a main support 311 and a truss 312 connected to the main support 311. The main support 311 comprises a first support 3111, a second support 3112 and a third support 3113, the lower end of the first support 3111 is provided with a steel groove 3114, limit holes 3115 are arranged on both sides of the steel groove 3114, and a moving slider 3116 is arranged in the steel groove 3114. The moving slider 3116 can slide in the steel groove 3114, and the material thereof can be a metal material with certain strength and wear resistance such as stainless steel, or a high-strength plastic. The moving slider 3116 is hinged to the end of the second support 3112 away from the truss 312, and the moving slider 3116 is detachably fixed in the steel groove 3114 through a limit pin 3117. The limit pin 3117 can be a cylindrical pin, which is used to fix the moving slider 3116 at a specific position in the steel groove 3114 to ensure the stability of the support structure. When it is necessary to adjust the relative position of the first support 3111 and the second support 3112, the limit pin 3117 can be pulled out, the moving slider 3116 can slide in the steel groove 3114, and after the position is adjusted, the limit pin 3117 is inserted to fix it. The first support 3111 is hinged to the third support 3113, and the second support 3112 is also hinged to the third support 3113, and the first support 3111 is slidingly connected to the second support 3112. This hinged and sliding connection makes the main support 311 have certain flexibility and adjustability, which can adapt to different test requirements. When testing wipers 4 and glasses 5 of different sizes, the overall shape and size of the support assembly 31 can be changed by adjusting the relative position of the first support 3111 and the second support 3112, so that the watering tool 3 can better cover the test area.

[0036] Specifically, the combination logic of these components constituting the support assembly 31 is that the first support 3111, the second support 3112 and the third support 3113 form the main support 311 through hinged and sliding connection, and the main support 311 is connected with the truss 312. Such combination makes the support assembly 31 have both stability and adjustability. The stability is reflected in the connection mode between the supports, which ensures that the structure will not easily shake, and the adjustability is reflected in the sliding connection of the first support 3111 and the second support 3112 and the hinged connection of them with the third support 3113, which can be flexibly adjusted according to actual conditions. Through this combination mode, the state of the support assembly 31 can be conveniently adjusted according to different sizes, shapes and other factors of the wiper 4 and the glass 5 during the test, so that the watering tool 3 can accurately water the test area, thereby providing a suitable rainfall simulation environment for the wiper 4.

[0037] The third support 3113 is fixedly connected with one end of the truss 312, and the fixing mode can adopt welding or bolt connection. The end of the third support 3113 away from the truss 312 is also connected with an auxiliary support 313, and the other end of the auxiliary support 313 is connected with the truss 312. The auxiliary support 313 can increase the overall stability of the support assembly 31, and can be a rod-shaped structure, and the material can be the same as that of the main support 311. When the test device is subjected to external force or vibration during operation, the auxiliary support 313 can share part of the stress, so as to prevent the support assembly 31 from deforming or being damaged.

The support frame 22 includes a bottom plate 221 and a support plate 222, and the workbench 21 is connected with the bottom plate 221 through the support plate 222. The workbench 21 is an inclined table top. The design of the inclined table top is beneficial to the natural flow of water on the glass 5, and is closer to the actual use scene. The bottom plate 221 extends outward at the low end of the workbench 21 to be provided with a base 223, and the base 223 is provided with a fixing hole 2231. The fixing hole 2231 can be used to fix the entire test device on the ground or other platform, so as to ensure the stability of the device. The support plate 222 is provided with an opening 2221. The opening 2221 can reduce the weight of the support frame 22 on the one hand, and is also convenient for wiring and other operations on the other hand. The workbench 21 is provided with an adhesive layer 211, which is black glue. The glass 5 is adhered to the adhesive layer 211. The glass 5 is the carrier for the wiper 4 to perform the test. The glass 5 is firmly fixed on the workbench 21 through the adhesive layer 211, so as to ensure that the wiper 4 normally works on the glass 5.
