Description

Technical Field

[0001] This utility model relates to the field of control boxes, and more particularly to a waterproof control box for underground parking space locks. Background Technology

[0002] An in-ground parking lock is a mechanical device installed on the ground to prevent others from occupying a parking space.

[0003] When installed, underground parking locks are completely underground. For example, Chinese patent application number 202322463495.9 discloses a ground-mounted parking lock, which provides a specific structure and working principle of an underground parking lock.

[0004] Because underground parking locks are located underground, water inevitably gets inside during the rainy season, which can easily damage the control board that controls the electrical appliances inside the lock.

[0005] In existing technologies, waterproof circuit boxes are commonly used. The specific structure of a waterproof control box is shown in Chinese patent application No. 201921684189.5, which discloses a waterproof circuit box for fire hydrants. When applied to underground parking locks, the control wires of the electrical appliances (motors, control lights, sensors) of the underground parking lock are run through the interior of the waterproof control box. The waterproof control box is used to prevent water from flowing into the control box and affecting the circuit board. However, because it is buried underground, the control box is easily soaked in water. When the control box is soaked in water, water can easily enter the control box through the wires connected to the electrical appliances, thus affecting the circuit board.

[0006] Existing technologies also include control boxes specifically designed to protect underwater equipment, which are filled with sealant. However, the downside of using sealant is that it is difficult to repair the circuitry when the circuit board fails, and usually the entire control box needs to be replaced, which increases maintenance costs.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. It should also be noted that the terminology used in this utility model is for describing specific implementations only and is not intended to limit the exemplary implementations according to this application.

[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without inventive effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] The waterproof control box for underground parking space locks provided in Embodiment 1 of this utility model, such as Figures 1 to 4 As shown, it includes a box body 1 and a box cover 2; the top of the box body 1 is open; the box cover 2 is detachably closed and fixed to the box body 2; a sealing groove 11 and a receiving groove 12 for placing a circuit board are provided inside the box body 1; the sealing groove 11 is provided on the side wall of the box body 1; a circuit hole 111 is opened on the side wall of the box body 1 to connect the sealing groove 11; the height of the groove opening of the sealing groove 11 is higher than the height of the bottom of the receiving groove 12.

[0025] The waterproof control box for underground parking space locks provided in Embodiment 1 of this utility model is used as an accessory for underground parking space locks. Underground parking space locks are existing technology. The structure provided in this embodiment is a control box for protecting the circuit board when installed in an underground parking space lock.

[0026] The waterproof control box for underground parking space locks provided in Embodiment 1 of this utility model has its opening facing upwards when assembled into the underground parking space lock. In the box body 1, the circuit board is fixed at the bottom of the receiving groove 12. The electrical appliances of the underground parking space lock pass through the circuit hole 111 into the sealing groove 11 via wires. The ends of these wires extend from the upward-facing opening of the sealing groove 11 and connect downwards again to the circuit board at the bottom of the receiving groove 12. Then, the box body 1 is sealed by the box cover 2 to prevent water from entering the receiving groove 12 from the top of the box body 1.

[0027] In this embodiment, the control box, when in use, in rainy environments (rainwater enters the underground parking lock, and the liquid level inside the lock increases with heavy rain), compared to existing control boxes, ensures that water entering the control box through the circuit hole 111 initially resides in the sealing groove 11. Only after the sealing groove 11 is submerged will water flow from the opening of the sealing groove 11 to the circuit board. (In existing technologies, even if the circuit hole 111 is directly above the box body 1, water will directly affect the circuit board via the wires through the circuit hole 111. This embodiment ensures that water submerges the control box until the water level is above the opening of the sealing groove 11 before flowing to and affecting the circuit board.) This protects the circuit board (while the water level is below the opening of the sealing groove 11). Furthermore, this embodiment does not use sealant to cover the circuit board, allowing maintenance personnel to easily repair the circuit board in case of failure.

[0028] The waterproof control box for underground parking space locks provided in Embodiment 1 of this utility model solves the problem of water ingress into the circuit board inside the control box of underground parking space locks in the prior art. It can waterproof the circuit board while avoiding the difficulty of repairing the circuit board when it fails.

[0029] As a preferred embodiment, this embodiment also includes a waterproof ring 3; a waterproof ring 3 is provided between the box body 1 and the box cover 2. The waterproof ring 3 is prior art. The waterproof ring 3, as a waterproof structure, is provided between the box body 1 and the box cover 2. It has been disclosed in the prior art in the Chinese patent application No. 201921684189.5, which discloses a waterproof circuit box for fire hydrants. This embodiment can use its structure, and will not be described in detail here.

[0030] As a preferred embodiment, the sealing groove 11 is filled with sealant. The sealant in the sealing groove 11 is existing technology. The sealant further restricts water from entering the sealing groove 11 from the circuit hole 111, thereby improving the waterproof effect of the control box. Furthermore, no sealant is applied to the circuit board, making it convenient for maintenance personnel to perform repairs in case of circuit board failure.

[0031] To further enhance the protection of the circuit board by the control box, as a preferred embodiment, a sensor fixing hole 112 is provided on the side wall of the box body 1; the sensor fixing hole 112 connects to the sealing groove 11; a water level sensor 4 is provided at the sensor fixing hole 112. The water level sensor 4 is existing technology, and it can monitor the water level outside the control box. When the water level outside the control box is higher than the opening of the sealing groove 11 (preferred in this embodiment), the power is cut off to the circuit board in the receiving groove 12, thereby protecting the circuit board.

[0032] As a preferred embodiment, this model also includes a horn 5; a fixing groove 13 is provided on the outer wall of the housing 1; the horn 5 is fixed in the fixing groove 13; a communication hole 113 communicating with the sealing groove 11 is provided in the fixing groove 13. After the sensor provides the water level signal to the circuit board, the circuit board provides a feedback signal to the horn 5 (through the wire between the circuit board and the horn 5, passing through the communication hole 113 to the fixing groove 13 outside the control box), causing the horn 5 to open and sound an alarm, reminding staff that the water level in the underground parking lock is too high and requires maintenance.

[0033] In summary, this utility model provides a waterproof control box for underground parking locks, relating to the field of control boxes, including a box body and a cover; the box body has an opening at the top; the cover is detachably fixed to the box body; the box body is provided with a sealing groove and a receiving groove for placing a circuit board; the sealing groove is located on the side wall of the box body; the side wall of the box body has a circuit hole communicating with the sealing groove; the height of the opening of the sealing groove is higher than the height of the bottom of the receiving groove. The waterproof control box for underground parking locks provided by this utility model solves the problem of water ingress into the circuit boards of existing underground parking lock control boxes, providing waterproof protection for the circuit boards while preventing difficulties in repairing faulty circuit boards.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
