Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock technology, specifically to a parking space lock and its waterproof structure. Background Technology
[0002] A parking space lock is a structure placed on a parking space to prevent unauthorized occupation of a private parking space. A parking space lock generally consists of a control unit and a barrier. When the parking space is not in use, the control unit raises the barrier, preventing other vehicles from entering. When the parking space is needed, the control unit lowers the barrier, allowing the target vehicle to enter smoothly. Because the parking space lock is placed directly on the parking space floor, and the control unit contains circuit boards and other structures, it needs to have good waterproof performance to prevent water seepage and damage to the internal structure during rain. The control unit and the barrier are driven by a main shaft, and there is a rotational relationship between the main shaft and the housing of the control unit. Even slight carelessness can lead to water leakage. Current technology typically uses a sealing ring between the main shaft and the housing, increasing the contact force between the sealing ring and the main shaft and housing. This structure is not only difficult to install but also results in high rotational friction on the main shaft, making the raising and lowering of the barrier less smooth. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof structure that can both ensure the waterproof performance of the parking lock and ensure the smooth rotation of the main shaft.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a waterproof structure, comprising: a housing, a main shaft, a bearing, and a sealing ring, wherein the bearing is installed in the housing, the main shaft is inserted into the bearing, and the sealing ring is sleeved on the end of the main shaft and seals the connection between the main shaft and the housing, wherein the bearing, the main shaft, the sealing ring, and the housing form a sealing space, and the sealing space is provided with rubber sealing grease.
[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: This waterproof structure can better achieve internal waterproofing of the parking lock by using the combination of sealing ring and rubber sealant. At the same time, the rubber sealant is filled in the sealed space formed between the bearing, main shaft, sealing ring and housing. The rubber sealant can remain in paste or semi-fluid state for a long time and has an extremely low coefficient of friction. While improving the internal waterproofing performance of the parking lock, it can also provide lubrication for the bearing, making the rotation of the main shaft smoother and facilitating the opening or closing of the parking lock.
[0006] In the aforementioned waterproof structure, a retaining ring is provided on the main shaft. The retaining ring is located on the outside of the bearing and is used to axially position the bearing.
[0007] The aforementioned waterproof structure also includes a side cover, which is sleeved on the outer end of the main shaft and fixed to the outside of the housing.
[0008] In the aforementioned waterproof structure, the side cover is fixedly connected to the housing by screws.
[0009] In the aforementioned waterproof structure, an air valve is provided on the side of the shell, and a waterproof and breathable membrane is provided inside the air valve to balance the pressure inside and outside the shell.
[0010] In the aforementioned waterproof structure, a mounting base is provided inside the housing, and the bearing and the sealing ring are both installed inside the mounting base, with the main shaft passing through the mounting base.
[0011] In the aforementioned waterproof structure, the side of the housing is provided with mounting ears, and the mounting ears are provided with mounting holes for the fixed installation of parking space locks.
[0012] In the above-mentioned waterproof structure, the rubber sealant is a fluorosilicone or lithium-based sealant.
[0013] In the aforementioned waterproof structure, the sealing ring is a double-lip structure or a sealing ring with a spring structure.
[0014] This utility model also provides a parking lock, including the aforementioned waterproof structure and a drive assembly for raising and lowering the parking barrier. This parking lock possesses at least all the beneficial effects of the aforementioned waterproof structure.
[0015] The aforementioned parking lock's drive assembly includes a motor, a reduction mechanism, and a transmission component connected to the main shaft, with the motor, reduction mechanism, and transmission component connected in sequence.
[0016] The aforementioned parking lock further includes a control circuit, which contains a wireless communication module for remotely controlling the raising and lowering of the parking lock.

[0020] Figure 3 This is a cross-sectional view of the waterproof structure according to an embodiment of the present invention.
[0021] The reference numerals are as follows: 100 housing, 110 mounting base, 120 mounting ear, 121 mounting hole, 200 spindle, 300 bearing, 400 sealing ring, 500 rubber sealant, 600 snap ring, 700 side cover, 800 screw. Detailed Implementation
[0022] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 3 This utility model provides a waterproof structure, including a housing 100, a main shaft 200, a bearing 300, and a sealing ring 400. The housing 100 is a protective shell for installing the internal circuitry and other structures of the parking lock control unit. The bearing 300 is installed inside the housing 100. One end of the main shaft 200 is located inside the housing 100 and is used to connect to the drive unit. The other end of the main shaft 200 is inserted into the bearing 300 and extends out of the housing 100 for connecting to the parking stop. Under the action of the drive unit, the main shaft 200 can rotate relative to the housing 100, causing the parking stop to swing towards the ground or rise. The sealing ring 400 can be a double-lip structure or a sealing ring with a spring structure. It is fitted onto the end of the main shaft 200 and seals the connection between the main shaft 200 and the housing 100. The bearing 300, the main shaft 200, the sealing ring 400, and the housing 100 form a sealed space. Rubber grease 500 is provided in the sealed space. The rubber grease 500 can be a high-temperature resistant, hydrolysis-resistant fluorosilicone or lithium-based grease. This waterproof structure, through the cooperation of the sealing ring 400 and the rubber grease 500, can better achieve waterproofing inside the parking lock. At the same time, the rubber grease 500, which fills the sealed space formed by the bearing 300, the main shaft 200, the sealing ring 400, and the housing 100, can maintain a paste or semi-fluid state for a long time and has an extremely low coefficient of friction. While improving the waterproof performance inside the parking lock, it can also provide lubrication for the bearing 300, making the rotation of the main shaft 200 smoother and facilitating the opening and closing of the parking lock. The external sealing ring 400 not only prevents external water from entering the sealed space, but also prevents the rubber sealant grease 500 inside the sealed space from leaking out of the housing 100.
[0023] Furthermore, a mounting base 110 is provided inside the housing 100, and the bearing 300 and the sealing ring 400 are both located inside the mounting base 110. The main shaft 200 passes through the mounting base 110. A retaining ring 600 is provided on the main shaft 200, located outside the bearing 300, which can cooperate with the mounting base 110 to hold the bearing 300 and provide axial positioning for the bearing 300. The waterproof structure also includes a side cover 700, which is sleeved on the outer end of the main shaft 200 and fixed to the outside of the housing 100. Specifically, the side cover 700 is fixedly connected to the housing 100 by screws 800. A mounting ear 120 is provided on the side of the housing 100, and the mounting ear 120 has a mounting hole 121, into which a threaded connector can be driven to fix the housing 100 in the desired position.
[0024] Furthermore, the side of the housing 100 is provided with an air valve, and the air valve is provided with a waterproof and breathable membrane. The waterproof and breathable membrane only allows gas to pass through and does not allow water to pass through. This ensures that the housing 100 can be ventilated inside and outside, so that the pressure inside and outside the housing 100 remains consistent, which can prevent the housing 100 from expanding or cracking, and also ensures the overall waterproof performance of the housing 100.
[0025] An embodiment of this utility model also provides a parking lock, including the aforementioned waterproof structure, which possesses at least all the beneficial effects of the aforementioned waterproof structure. Further, the parking lock includes a drive assembly for driving the parking stop to rise and fall. The drive assembly includes a motor, a reduction mechanism, and a transmission component connected to the main shaft 200, with the motor, reduction mechanism, and transmission component connected in sequence. Further, the parking lock includes a control circuit, which includes a wireless communication module for remotely controlling the raising and lowering of the parking lock.
