Description

Technical Field

[0001] This utility model belongs to the field of wiper lever testing technology, and in particular relates to a wiper lever durability testing device. Background Technology

[0002] The windshield wiper stalk is a lever on a vehicle used to control the operation of the windshield wipers. It is usually located on the right or left side of the steering wheel, with the exact location varying depending on the car model. Its main function is to turn the wipers on and off, adjust their speed, and spray water to clean the windshield through different operating methods. While the design and function of the stalk may differ from car model and manufacturer, the basic operating logic is similar. Moving the stalk up or down activates different wiper operating modes.

[0003] In a simulated rainy test environment, the wiper lever needs to be operated frequently to simulate various precipitation conditions in real-world scenarios, such as light rain, moderate rain, and heavy rain. Because the test requires long-term operation to verify the durability and reliability of the wipers, the washer system must operate continuously to ensure the windshield surface remains constantly wet, thus simulating the effect of real rain rinsing.

[0004] However, this continuous water spraying results in a significant amount of water being directly lost and unable to be recycled, leading to substantial water waste. This problem is particularly pronounced in large-scale testing or repeated validation scenarios, not only increasing testing costs but also negatively impacting environmental sustainability.

[0005] Furthermore, the accumulation of sprayed water in the testing area can cause slippery surfaces, affecting the safety of testing personnel and potentially interfering with the normal operation of other testing equipment. Due to the lack of an effective water recycling mechanism, the amount of water consumed during testing far exceeds actual needs, further highlighting the problem of inefficient resource utilization. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a wiper lever durability testing device. This device facilitates simulated rainy weather durability testing of the lever body and allows for water filtration and recycling, thus saving water resources.

[0007] In view of this, the present invention provides a device for testing the durability of a windshield wiper lever, comprising:

[0032] Please see Figures 1 to 6 The embodiments provided by this utility model are as follows:

[0033] Example 1: A wiper lever durability testing device, comprising:

[0034] Box 4, the inner cavity of box 4 is equipped with detection mechanism 8, the lower end of box 4 is detachably equipped with conical container 5, the lower end of conical container 5 is detachably equipped with installation plate 6, the lower end of installation plate 6 is equipped with round box 3, the inner cavity of round box 3 is fixed with filter cylinder 10, the lower end of round box 3 is opened with through hole 30, the lower end of round box 3 is fixed with conical container 7, the lower end of round box 3 is fixed with pipe 23, one end of the outer wall of round box 3 is fixed with pipe 29.

[0035] The housing 4 serves as the core load-bearing structure, and its internal detection mechanism 8 simulates the movement of a windshield wiper under real-world conditions. Liquid waste generated during the detection process is initially collected through the inclined inner wall of the conical collection box 5 and guided to the circular box 3 via the mounting plate 6. The filter cartridge 10 fixed inside the circular box 3 performs solid-liquid separation; after impurities are intercepted, the clean liquid enters the conical collection box 7 through the through-hole 30 for secondary collection. Pipes 23 and 29 constitute the waste liquid discharge and circulation pipelines, respectively.

[0036] One end of the housing 4 is rotatably connected to the door 13. A slot 12 is opened inside the housing 4. The detection mechanism 8 is fixed in the slot 12. A windshield 16 is installed on the detection mechanism 8. A wiper body 17 is installed on the detection mechanism 8. A lever body 32 is installed at one end of the wiper body 17. A nozzle 9 is fixed at the upper end of the housing 4. The lower end of the nozzle 9 extends into the slot 12.

[0037] The housing 4 is opened and closed quickly via a hinged door 13, facilitating the installation and maintenance of the wiper body 17 and the lever body 32. The housing trough 12 serves as a sealed testing space, where a fixed testing mechanism 8 controls the activation of the lever body 32, thereby controlling the wiping frequency and angle of the wiper body 17 on the windshield 16 surface. The nozzle 9 extends into the housing trough 12, simulating different precipitation conditions such as heavy rain and drizzle, and reproducing complex environmental conditions by adjusting the spray angle and flow rate. The windshield 16 features a detachable design, allowing for easy replacement of test samples with different surface textures to verify the lever's durability. The overall structure significantly improves the diversity of testing scenarios and ease of operation while ensuring testing accuracy.

[0038] Furthermore, a through hole 14 is opened at the lower end of the box body 4, a ring 11 is fixed at the lower end of the box body 4, an annular screw groove 15 is opened at the lower end of the ring 11, a mounting ring 19 is fixed at the upper end of the conical container 5, and a threaded ring 20 is fixed at the upper end of the mounting ring 19. The threaded ring 20 extends into the annular screw groove 15 and is threadedly connected.

[0039] A through hole 14 at the lower end of the housing 4 guides the liquid generated during the testing process downwards, ensuring that waste liquid does not stagnate inside the housing 4. The circular ring 11 and the annular threaded groove 15 form a detachable connection structure, allowing the conical container 5 to be quickly installed and removed via the engagement of the threaded ring 20 and the mounting ring 19. This threaded connection not only improves the equipment's sealing performance and prevents liquid leakage but also facilitates maintenance and cleaning. When it is necessary to replace or clean the conical container 5, simply unscrew the threaded ring 20 to easily separate the components, significantly improving the maintainability of the equipment.

[0040] Furthermore, a through hole 21 is opened at the lower end of the conical container 5, a ring 18 is fixed at the lower end of the conical container 5, an annular threaded groove 28 is opened at the lower end of the ring 18, a pipe 27 is fixed at the upper end of the mounting plate 6, a threaded ring 26 is fixed at the upper end of the pipe 27, the threaded ring 26 extends into the annular threaded groove 28 and is threadedly connected.

[0041] The through hole 21 at the lower end of the conical container 5 and the annular ring 18 form a waste liquid guide channel, ensuring that the liquid smoothly enters the next treatment stage. The threaded connection between the annular screw groove 28 and the threaded ring 26 allows the mounting plate 6 to be firmly fixed below the conical container 5 while maintaining a seal to prevent liquid leakage. The design of the pipe 27 further optimizes the liquid flow path, ensuring that the waste liquid can efficiently enter the circular box 3 for filtration. This structure not only enhances the stability of the equipment but also improves the smoothness of liquid flow and reduces residue.

[0042] Furthermore, a circular groove 25 is opened at the upper end of the circular box 3, and the mounting plate 6 is inserted into the circular groove 25.

[0043] The circular groove 25 at the upper end of the circular box 3 is threaded into the mounting plate 6, allowing the mounting plate 6 to be precisely positioned and securely installed on the circular box 3. This structural design simplifies the assembly process while ensuring the sealing of the connection points to prevent liquid leakage.

[0044] Furthermore, a circular groove 24 is formed at the bottom of the inner wall of the second circular groove 25, and the filter cylinder 10 is installed in the first circular groove 24. The filter cylinder 10 is aligned with the vertical axis of the through hole 30.

[0045] Circular trough 24, located at the bottom of circular trough 25, is used to install filter cartridge 10, ensuring that filter cartridge 10 is vertically aligned with through hole 30, allowing the liquid to flow evenly into filter cartridge 10 for filtration. The installation method of filter cartridge 10 makes it easy to replace or clean, while ensuring stable filtration performance. This structure optimizes the waste liquid treatment process, effectively intercepting solid impurities, while the filtered liquid can smoothly enter the next stage collection device, improving the environmental friendliness and sustainability of the equipment.

[0046] Furthermore, the lower end of the conical container 27 is fixed with pipe 4 31, and the lower end of pipe 4 31 is connected with flexible hose 22.

[0047] The conical container 27 has a lower pipe 4 31 for discharging the filtered liquid, and the flexible hose 22's sleeve design allows the liquid to be guided to an external circulation system. The flexibility of the hose 22 allows the equipment to adapt to different environments and facilitates adjustment of the liquid discharge direction. This enhances the equipment's flexibility, enabling it to adapt to different testing scenarios while reducing the risk of liquid splashing and maintaining a clean working environment.

[0048] Furthermore, four support rods 2 arranged in a rectangular row are fixed at the lower end of the box body 4, and the bottom of the four support rods 2 are respectively fixed with a base plate 1.

[0049] The four support rods 2 at the lower end of the housing 4 are arranged in a rectangular array, providing a stable support structure and ensuring that the equipment will not tilt or shift due to vibration or load changes during operation. The chassis 1 further enhances the overall stability of the equipment, enabling it to adapt to different ground conditions.

[0050] In this embodiment, when the wiper lever needs to undergo durability testing, at the start of the test, the operator securely mounts the windshield 16 to be tested onto the testing mechanism 8 and adjusts the wiper body 17 to the standard installation position. The testing mechanism 8 then starts a preset program, causing the lever body 32 to perform regular reciprocating motions, enabling the wiper body 17 to perform wiping actions at different angles and speeds on the surface of the windshield 16, fully simulating actual usage scenarios.

[0051] During operation, nozzle 9 sprays water at different flow rates according to the testing requirements, creating a realistic rainfall environment within the tank 12. After impacting the windshield 16, the water flows naturally down the glass surface, realistically reproducing the water film state during rainy driving. The water generated during the testing process enters the conical collection tank 5 through the through-hole 14 at the bottom of the tank 4. Its unique conical structure design ensures that the wastewater can quickly collect at the bottom through-hole 21.

[0052] The wastewater then enters the circular trough 24 inside the circular box 3 through pipe 27, where the filter cartridge 10 performs fine filtration. The filter cartridge 10 effectively traps impurities such as rubber particles and dust in the water, while the filtered clean water enters the conical holding tank 7 through the through hole 30. Finally, this purified water is transported to the external circulation system through pipe 31 and the adjustable-angle hose 22, realizing the reuse of water resources.

[0053] When the filter cartridge 10 requires maintenance, the operator can connect a high-pressure cleaning water stream through pipe 29. The water stream flows in the opposite direction, flushing the surface of the filter cartridge 10 to thoroughly remove accumulated impurities. The wastewater generated during cleaning is discharged into a dedicated collection device through pipe 23 to avoid secondary pollution. The entire cleaning process does not require disassembling the filter cartridge 10, greatly improving maintenance efficiency. This facilitates simulated rainy weather durability testing of the wiper body 17, while also allowing for water filtration and recycling, thus conserving water resources.

[0054] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
