Description

Technical Field

[0001] This utility model relates to the field of wiper motor technology, and in particular to an automotive wiper motor with a reset plate. Background Technology

[0002] The windshield wiper motor is the core component of the windshield wiper system. It uses electricity to drive the wiper arms to swing left and right across the windshield, cleaning rainwater and dirt. The motor typically works with a transmission, reset plate, and limit switches to control the wiper's movement mode and stopping position. Modern car wiper motors often also feature different speed settings and intermittent operation modes to adapt to various weather conditions and driving needs. The reset plate of the windshield wiper motor is usually installed inside the motor body; its main function is to ensure that the wipers return to the appropriate position after the motor is turned off.

[0003] A search revealed Chinese Patent Publication No. CN215186280U, which discloses an automotive wiper motor with a reset plate and a reduction gear, effectively improving the heat dissipation capacity of the wiper motor. The motor includes a first housing containing a motor. A heat dissipation mechanism is located on the right side of the motor, comprising vertical plates, horizontal bars, gears, a gear ring, and fan blades. One end of each of the two vertical plates is rotatably connected to the horizontal bars via bearings. Fan blades are fixed to the top and bottom of the left ends of the two horizontal bars. This automotive wiper motor with a reset plate and reduction gear, through the cooperation of the vertical plates, horizontal bars, gears, gear ring, and fan blades, allows the motor to drive the two horizontal bars to revolve via the vertical plates during operation. The meshing of the two gears and gear rings allows the two horizontal bars to rotate independently during their revolution, thereby enabling the two horizontal bars to drive multiple fan blades to provide omnidirectional airflow to the motor, solving the problem of inadequate heat dissipation in wiper motors.

[0004] While the above-mentioned technical solutions effectively improve the heat dissipation capacity of the wiper motor, the disassembly and installation of the plate through the cooperation of the transmission mechanism and the fixing mechanism requires a large number of structures and is relatively complex in design, which increases the cost of maintaining related components. Therefore, a car wiper motor with a reset plate is proposed to solve the above problems. Utility Model Content

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an automotive wiper motor with a reset plate, comprising a housing 1, a plate 2 on one side of the housing 1, a quick-release assembly 5 installed inside the plate 2, a housing 3 on the other side of the housing 1, a drive assembly 7 installed inside the housing 3, a wiper assembly mounting plate 4 on the side of the housing 3, and a fixing assembly 6 installed inside the wiper assembly mounting plate 4; the quick-release assembly 5 includes a fixing post 8, which is fixedly connected to the side of the plate 2, and two clamping plates 9 are slidably connected to the outside of the fixing post 8, each clamping plate 9 having a locking block 10 fixedly connected to its outside, the clamping plates 9 moving outward or inward on the fixing post 8 with the locking block 10, and each clamping plate 9 having a sliding block 11 fixedly connected to its side, the sliding block 11 controlling the clamping plates 9 to move downward with the locking block 10. A spring 12 is fitted around the outer periphery of the fixed column 8, and the spring 12 is positioned between the two clamping plates 9. The pressure applied by the spring 12 to the clamping plates 9 causes them to move outward along with the locking block 10. A sliding groove 13 is provided inside the plate body 2, and the sliding block 11 is slidably connected inside the sliding groove 13. The sliding groove 13 provides space for the sliding block 11 to move. A locking slot 14 is provided inside the box body 1, and the locking block 10 engages with the locking slot 14. By applying pressure to the clamping plates 9, the locking blocks 9 are engaged with the locking blocks 10 and inserted into the locking slot 14, completing the installation of the plate body 2.

[0034] Reference Figure 1 and Figure 3The fixing component 6 includes a connecting plate 15, which is fixedly connected to the side of the wiper assembly mounting plate 4. A fixing plate 16 is fixedly connected inside the wiper assembly mounting plate 4. A spring telescopic rod 17 is mounted on the side of the fixing plate 16. One end of the spring telescopic rod 17 is fixedly connected to a stop plate 18, which is positioned between the spring telescopic rod 17 and the connecting plate 15. The pressure generated by the cooperation of the fixing plate 16 and the spring telescopic rod 17 causes the stop plate 18 to move towards the connecting plate 15. A locking block 19 is fixedly connected to the side of the housing 3. The connecting plate 15 has a sliding groove 20 and a locking slot 21 inside. The locking block 19 is slidably connected inside the sliding groove 20, and the locking block 19 and the locking slot 21 engage with each other. The locking block 19 enters the connecting plate 15 from the sliding groove 20. The pressure applied to the locking block 19 by the stop plate 18 causes it to engage inside the locking slot 21, thus completing the installation of the wiper motor on the wiper assembly mounting plate 4.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The drive assembly 7 includes a motor 22, which is installed inside housing 1. A worm gear 23 is fixedly connected to the output end of the motor 22. The worm gear 23 is rotatably connected inside housing 23. A rotating column 24 is rotatably connected inside housing 23. A worm wheel 25 is fixedly connected to the outer side of the rotating column 24. The motor 22 drives the worm gear 23 to rotate, causing the worm wheel 25 to rotate along with the rotating column 24. A reset plate 26 is fixedly connected to the outer side of the rotating column 24, and a reset contact 27 is fixedly connected to the inner side of housing 23. One end of the reset contact 27 is located on the surface of the reset plate 26. When the driver turns off the windshield wiper switch, the wiper motor does not stop immediately but continues to run until a protrusion on the reset plate 26 triggers the reset contact 27. After the contact disconnects the circuit, the wiper motor stops running, and the wipers automatically stop at the bottom of the windshield or a designated position.

[0036] Working principle: When it is necessary to disassemble plate 2 and maintain the internal structure of box 1 and box 2 3, move the sliding block 11 inward, so that the sliding block 11, along with the clamping plate 9 and the locking block 10, moves inward and disengages from the locking slot 14 of box 1, thus completing the disassembly of plate 2. When it is necessary to reinstall plate 2, move the sliding block 11 inward again, place plate 2 on the side of box 1, and place the clamping plate 9 and the locking block 10 into the interior of box 1. When the locking block 10 is aligned with the locking slot 14, the pressure applied to the clamping plate 9 by the spring 12 causes the locking block 10 to engage with the locking slot 14, thus completing the installation of plate 2.

[0037] When installing the wiper motor onto the wiper assembly, align the second locking block 19 on the side of the housing 23 with the sliding groove 20 on the side connecting plate 15 of the wiper assembly mounting plate 4, slide it into the connecting plate 15, and then rotate the wiper motor so that the second locking block 19 aligns with the second locking groove 21 of the connecting plate 15. Through the cooperation of the spring telescopic rod 17 and the abutment plate 18, the locking block 19 is pressed into the second locking groove 21, thus completing the installation of the wiper motor.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
