Description

[0003] When the automobile window motor is running, the internal pressure fluctuates due to temperature and component movement, and it faces harsh environments during driving. Therefore, it is necessary to prevent water from entering and maintain a waterproof and breathable state. The waterproof and breathable valve of the automobile window motor can effectively balance the internal pressure, block pollutants such as rainwater and dust, ensure the stable operation of the motor, and prolong its service life and performance reliability.

[0004] However, the existing waterproof and breathable valve of the automobile window motor has the following disadvantages:

[0005] In the prior art, the waterproof and breathable valve of the automobile window motor is designed with a fixed and small air hole. During the actual use of the window motor, due to the thermal expansion and cold contraction effect caused by sudden changes in environmental temperature, or the instantaneous compression of internal air caused by frequent and rapid lifting of the window, the internal pressure of the motor will increase sharply, resulting in a large pressure difference between the inside and outside. The small air hole cannot discharge the high-pressure gas inside to balance the pressure in time, eventually causing the sealing components of the motor to bear excessive pressure, accelerating the aging, deformation, and even rupture of the sealing components, and affecting the waterproof performance and normal service life of the window motor.

[0006] Therefore, we propose a waterproof and breathable valve of the automobile window motor to solve the above problems. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0023] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and examples. It should be explained that the examples and features in the examples of the present application can be combined with each other without conflict.

[0024] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, therefore, the utility model is not limited to the specific examples disclosed in the following disclosure.

[0025] Example 1, as shown in the accompanying drawings Figure 1 - the accompanying drawings Figure 4As shown, the utility model provides a technical scheme: a waterproof breather valve of automobile window shaking executor, including threaded interface 1, the outer surface wall of threaded interface 1 is movably sleeved with O-shaped sealing ring 2, the top of threaded interface 1 is fixedly connected with connecting seat 3, the inner surface wall of connecting seat 3 is provided with waterproof breather membrane 4, the top of waterproof breather membrane 4 is fixedly connected with gasket 5, the top of gasket 5 is fixedly connected with first spring 6, the top of first spring 6 is fixedly connected with sliding plate 7, the outer surface wall of sliding plate 7 is movably sleeved with protective cover 8, the inner surface wall of protective cover 8 is provided with two first sliding grooves 9, and the outer surface wall of sliding plate 7 is movably inserted in the inside of two first sliding grooves 9, the outer surface wall of protective cover 8 is provided with a group of breather holes 10, the top of protective cover 8 is provided with threaded groove 11, the inner surface wall of threaded groove 11 is threadedly connected with adjusting screw 12, the top of adjusting screw 12 is fixedly connected with knob 13, the outer surface wall of adjusting screw 12 is movably sleeved with bearing 14, and the outer surface wall of bearing 14 is fixedly inserted in the inside of sliding plate 7.

[0026] The effect reached by the whole embodiment 1 is: when the pressure in the window shaking executor increases suddenly, the gas will flow to the direction of protective cover 8 through waterproof breather membrane 4, at this time, sliding plate 7 will play a role of initially blocking the gas, and with the enhancement of gas pressure, the gas will push sliding plate 7 to move upwards and stretch first spring 6 in the process, with the upwards movement of sliding plate 7, it will gradually increase the contact area of a group of breather holes 10 with the internal air, thereby accelerating the release rate of high-pressure gas, so that the internal pressure of window shaking executor can quickly restore balance, when the internal pressure reduces to a certain extent, first spring 6 will use its elastic restoring force to push sliding plate 7 to reset, thereby closing or reducing the area of breather hole 10, to avoid too much dust and moisture from entering the inside of protective cover 8 through too large breather hole 10, to play an effective protection role, in addition, by rotating knob 13 and using the transmission mechanism of threaded assembly, the position of sliding plate 7 can be adjusted to move downwards and compress first spring 6, this adjustment mode not only can change the spring constant of spring, but also can accurately control the pre-compression amount, thereby realizing the accurate control of pressure relief starting pressure.

[0027] As shown in the embodiment 2, Figures 2-4 The bottom of protective cover 8 is fixedly connected with embedding block 15, the outer surface wall of embedding block 15 is provided with two limiting grooves 16, the top of connecting seat 3 is provided with embedding groove 17, and the outer surface wall of embedding block 15 is movably inserted in the inside of embedding groove 17, the outer surface wall of connecting seat 3 is provided with two second sliding grooves 18, the inner surface wall of two second sliding grooves 18 is slidably embedded with sliding block 19, the outer wall of two sliding blocks 19 is fixedly connected with limiting block 20 on one side, and the outer surface wall of two limiting blocks 20 is movably inserted in the inside of two limiting grooves 16, the outer surface wall of two sliding blocks 19 is fixedly connected with pull block 21, and the outer wall of two sliding blocks 19 is fixedly connected with second spring 22 on the other side.

[0028] The effect achieved by the whole embodiment 2 is that by moving the two pull blocks 21, the two sliding blocks 19 can be driven to move synchronously to one side, and the displacement of the two sliding blocks 19 will further drive the two limiting blocks 20 to smoothly move out of the corresponding limiting grooves 16, thereby effectively releasing the fixing constraint on the embedded block 15 and the protective cover 8. By using this quick connection method, the user can quickly disassemble the protective cover 8, greatly facilitating the subsequent maintenance work, and allowing convenient inspection, replacement or repair of the waterproof and breathable valve and the waterproof and breathable membrane 4 inside it. These steps not only ensure the continuous and reliable operation of the equipment, but also effectively prolong the service life of the waterproof and breathable valve and its components.

[0029] The working principle of the whole device is as follows: in use, first, the threaded interface 1 is stably connected with the automobile window executioner, and the sealing performance of the connection is ensured by the O-shaped sealing ring to prevent gas or liquid leakage. When the pressure in the window executioner suddenly increases due to temperature rise or operation, the gas will smoothly move to the protective cover 8 through the waterproof and breathable membrane 4. At this time, the sliding plate 7 will temporarily block the large amount of gas from escaping directly, and the accumulated force of the gas will push the sliding plate 7 to move upward and stretch the first spring 6 connected thereto. With the upward movement of the sliding plate 7, the area of the set of gas vents 10 below it gradually increases, thereby accelerating the release rate of high-pressure gas, which helps to quickly restore the pressure balance state in the window executioner. Subsequently, under the elastic restoring force of the first spring 6, the sliding plate 7 will slowly reset. This process not only ensures that the area of the gas vents 10 returns to the appropriate state, but also effectively prevents excessive dust and moisture from entering the inside of the protective cover 8 due to the excessive size of the gas vents 10, thereby maintaining the cleanliness and dryness of the executioner interior environment. In addition, by rotating the knob 13, the knob 13 will drive the adjusting screw 12 to rotate synchronously. By using the thread cooperation between the adjusting screw 12 and the threaded groove 11, the downward movement distance of the adjusting screw 12 can be accurately controlled, thereby driving the sliding plate 7 to move downward and compress the first spring 6. This adjustment mechanism allows the user to adjust the spring constant and pre-compression according to actual needs, thereby accurately controlling the starting pressure of the pressure relief and improving the adaptability and flexibility of the device. When it is necessary to regularly clean or maintain the waterproof and breathable membrane 4 and the interior of the valve body, the user only needs to simply move the two pull blocks 21 to drive the two sliding blocks 19 to move synchronously to one side. This action will drive the two limiting blocks 20 to smoothly move out of the respective limiting grooves 16, thereby releasing the fixing constraint on the embedded block 15 and the protective cover 8. By using this design, the user can easily disassemble the protective cover 8, which greatly facilitates the subsequent cleaning and maintenance of the waterproof and breathable membrane 4 and the interior of the valve body.

[0030] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
