Description

Technical Field

[0001] This utility model relates to the field of wiper motor technology, and in particular to a waterproof wiper motor for engineering vehicles. Background Technology

[0002] Engineering vehicles often operate in harsh environments, such as heavy rain, mud, and dust. As a key component to ensure clear visibility for the driver of engineering vehicles, the wiper motor includes a motor housing (including a housing assembly), a gearbox assembly, a gearbox housing, and a motor end connector assembly.

[0003] The main water inlet for the wiper motor is at the motor connector, specifically the motor input wire. This input wire needs to pass through the motor housing and connect to the motor inside. However, there is a large gap between the input wire and the housing, which allows rainwater to easily enter the motor housing, causing short circuits and damage to the motor, thus affecting the normal operation of the wipers. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: there is a large gap between the motor input line and the housing, which makes it easy for rainwater to enter the motor housing, causing short circuits and damage to the motor, and affecting the normal operation of the wipers. Therefore, this invention proposes a waterproof wiper motor for engineering vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof windshield wiper motor for engineering vehicles includes a motor housing and a gearbox housing, wherein the gearbox housing has a connecting channel on its side that communicates with the interior of the motor housing.

[0007] The inner wall of the connecting channel has an annular groove, and a rubber sealing ring is fixedly installed in the annular groove. The side of the sealing ring away from the motor housing has a slot with a trapezoidal longitudinal section. Multiple mounting blocks are fixedly installed on the inner wall of the connecting channel. Each of the mounting blocks has a horizontally opening movable hole. A movable rod is horizontally slidably installed in each of the movable holes. A top ring with a trapezoidal longitudinal section is fixedly installed at the end of each movable rod near the sealing ring. The top ring is inserted into the slot. The gearbox housing is provided with a movable component for driving the multiple movable rods to move simultaneously.

[0008] Preferably, the moving component includes a threaded sleeve, a rotating sleeve, and a rotating ring rotatably mounted on one end of the rotating sleeve via a rotating component, with one end of each of the multiple moving rods fixedly connected to the rotating ring. The inner sidewall of the threaded sleeve has an external thread, and the outer sidewall of the rotating sleeve has an internal thread. The internal and external threads mesh with each other, and the threaded sleeve is mounted on one end of the connecting channel.

[0009] Preferably, the rotating component includes an annular groove formed at one end of the rotating sleeve and a rotating ring slidably installed in the annular groove, wherein the rotating ring is fixedly connected to the rotating sleeve.

[0010] Preferably, the outer surface of the rotating sleeve is provided with a plurality of anti-slip grooves, and the number of anti-slip grooves is not less than ten.

[0011] Preferably, a water collection trough is provided at the bottom of the connecting channel, and a water outlet is provided at the bottom of the water collection trough.

[0012] Preferably, a waterproof cover is fixedly installed on the gearbox housing, and the waterproof cover is located directly below the water outlet.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When the motor input line is installed in the connection channel, the top rod is inserted into the socket through the cooperation of the sealing ring, the moving rod, the top ring and the moving component. This causes the sealing ring to deform and make tight contact with the motor input line, reducing the gap between the sealing ring and the motor input line. This effectively prevents rainwater from entering the motor through the connection channel and ensures the normal operation of the wiper motor.

[0015] 2. When a small amount of rainwater enters the connecting channel, it can be quickly drained through the water collection tank and water outlet, thus preventing rainwater from accumulating inside the motor. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-8 A waterproof windshield wiper motor for engineering vehicles includes a motor housing 1 and a gearbox housing 2. The gearbox housing 2 has a connecting channel 3 on its side that communicates with the inside of the motor housing 1. The motor is installed inside the motor housing 1, and the gearbox assembly is installed inside the gearbox housing 2. Neither the motor nor the gearbox assembly is shown in the figure.

[0027] An annular groove is provided on the inner wall of the connecting channel 3. A rubber sealing ring 4 is fixedly installed in the annular groove. A trapezoidal insertion port 5 is provided on the side of the sealing ring 4 away from the motor housing 1. Multiple mounting blocks 6 are fixedly installed on the inner wall of the connecting channel 3. Each mounting block 6 has a horizontally opening movable hole. A movable rod 7 is horizontally slidably installed in each of the multiple movable rods 7. A trapezoidal top ring 8 is fixedly installed at the end of each movable rod 7 near the sealing ring 4. The top ring 8 is inserted into the insertion port 5. A movable component is provided on the gearbox housing 2 to drive the multiple movable rods 7 to move simultaneously.

[0028] When connecting the motor input line, one end passes through the connecting channel 3 and extends into the motor housing 1. At the same time, the sealing ring 4 is fitted onto the motor input line. Then, the moving component drives multiple moving rods 7 to move simultaneously toward the sealing ring 4. During the movement, the moving rods 7 will drive the top ring 8 to move toward the socket 5. When the top ring 8 is inserted into the socket 5, it will cause the inner ring of the sealing ring 4 to deform toward the motor input line, thereby making the sealing ring 4 in close contact with the motor input line, reducing the gap between the sealing ring 4 and the motor input line, effectively preventing rainwater from entering the motor through the connecting channel 3, and ensuring the normal operation of the wiper motor.

[0029] The moving assembly includes a threaded sleeve 9, a rotating sleeve 10, and a rotating ring 11 rotatably mounted on one end of the rotating sleeve 10 via a rotating component, all fixedly mounted on the gearbox housing 2. One end of each of the multiple moving rods 7 is fixedly connected to the rotating ring 11. The inner wall of the threaded sleeve 9 has an external thread, and the outer wall of the rotating sleeve 10 has an internal thread. The internal and external threads mesh with each other. The threaded sleeve 9 is mounted on one end of the connecting channel 3. The outer surface of the rotating sleeve 10 has multiple anti-slip grooves, with no fewer than ten anti-slip grooves. The threaded sleeve 9 is threadedly connected to the rotating sleeve 10 via the internal and external threads. When it is necessary to move multiple moving rods 7 simultaneously, it is only necessary to rotate the rotating sleeve 10, causing the rotating sleeve 10 to rotate on the threaded sleeve 9. Under the action of the internal and external threads, the rotating sleeve 10 will move towards the sealing ring 4, and then the rotating ring 11 will drive multiple moving rods 7 to move simultaneously.

[0030] The rotating component includes an annular groove at one end of the rotating sleeve 10 and a rotating ring 12 slidably installed in the annular groove. The rotating ring 12 is fixedly connected to the rotating ring 11. When the rotating sleeve 10 rotates, the rotating ring 11 will rotate relative to the rotating sleeve 10 through the rotating ring 12, so that the rotating ring 11 can move horizontally within the connecting channel 3.

[0031] A water collection trough 13 is provided at the bottom of the connecting channel 3, and a water outlet 14 is provided at the bottom of the water collection trough 13. A waterproof cover 15 is fixedly installed on the gearbox housing 2. The waterproof cover 15 is located directly below the water outlet 14. When a small amount of rainwater enters the connecting channel 3, it can be quickly discharged through the water collection trough 13 and the water outlet 14, thereby preventing rainwater from accumulating inside the motor. The waterproof cover 15 can prevent external rainwater from entering the connecting channel 3 through the water outlet 14.

[0032] In this invention, when the motor input line is connected, one end passes through the connecting channel 3 and extends into the motor housing 1. At the same time, the sealing ring 4 is fitted onto the motor input line. Then, the moving component drives multiple moving rods 7 to move simultaneously toward the sealing ring 4. During the movement, the moving rods 7 will drive the top ring 8 to move toward the socket 5. When the top ring 8 is inserted into the socket 5, it will cause the inner ring of the sealing ring 4 to deform toward the motor input line, thereby making the sealing ring 4 in close contact with the motor input line, reducing the gap between the sealing ring 4 and the motor input line, effectively preventing rainwater from entering the motor through the connecting channel 3, and ensuring the normal use of the wiper motor.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
