Description

Technical Field

[0001] This utility model belongs to the field of protective device technology, specifically relating to a safe and theft-proof charging pile cabinet. Background Technology

[0002] With the development of new energy equipment, the coverage of charging devices for new energy equipment is also constantly increasing. Most of these charging piles are directly installed on the ground or hung on the wall. However, due to the lack of relevant protective structures, they are easily dismantled or damaged by outsiders, resulting in property damage. At the same time, when installing and protecting charging piles, ordinary protective cabinets are also easily opened by force, resulting in the direct removal of the equipment. Overly complicated installation methods can also lead to cumbersome disassembly and assembly steps. Therefore, there is a need for a cabinet that is easy to disassemble and assemble and has high safety protection during use to protect the charging piles. Summary of the Invention

[0003] The purpose of this utility model is to provide a secure and theft-proof charging pile cabinet to solve the problems mentioned in the background art.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A secure and anti-theft charging pile cabinet includes a cabinet body, a carrier plate for installing charging piles is provided on the rear wall of the cabinet body, the cabinet body is connected to the external wall by bolts and the connection point is in the coverage area of ​​the carrier plate, and a locking mechanism is provided between the carrier plate and the cabinet body.

[0006] The number of locking mechanisms is at least two and they are symmetrically distributed along the cabinet. The carrier plate is provided with locking pins, and the cabinet has lock holes that match the locking pins. Each locking mechanism includes four locking pins that are distributed around the lock holes in the cabinet. The locking pins have limiting holes that match the locking pins.

[0007] The locking pin includes an electromagnet, a spring element, and a pin head. The cabinet has a stepped cavity that communicates with the lock hole. The electromagnet is located in the stepped cavity on the side away from the lock hole. The spring element is connected to the electromagnet. The pin head is connected to the other end of the spring element and extends into the lock hole. The side of the pin head facing the lock hole opening is inclined and matches the limiting hole of the lock pin.

[0008] The elastic element is either a sheet or a spring.

[0009] The cabinet has a door on the front side, and a lock is provided between the door and the cabinet.

[0010] The front side of the carrier plate has a double hole that matches the position of the locking pin. The diameter of the double hole is smaller than that of the locking pin and penetrates through the locking pin. The locking mechanism also includes a magnetic rod that matches the double hole.

[0011] This application has at least the following advantages compared to the prior art:

[0012] By setting up a locking mechanism, a stable connection can be provided to the cabinet and charging pile during installation. At the same time, the connection points between them can be shielded by the carrier plate, thus forming a prerequisite for unlocking and preventing unauthorized disassembly by external personnel. The locking pin cooperates with the locking post of the carrier plate to further improve the security of the connection and lock. Different connection requirements are provided in different scenarios of disassembly, assembly and limiting, which is more conducive to the safety protection of the device.

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-5 As shown, a safe and anti-theft charging pile cabinet includes a cabinet body 1, a carrier plate 2 for installing charging piles is provided on the inner rear wall of the cabinet body 1, the cabinet body 1 is connected to the outer wall by bolts and the connection point is in the coverage area of ​​the carrier plate 2, and a locking mechanism is provided between the carrier plate 2 and the cabinet body 1.

[0022] The number of locking mechanisms is at least two and they are symmetrically distributed along the cabinet 1. The carrier plate 2 is provided with locking pins 21. The cabinet 1 has lock holes 11 that match the locking pins 21. Each locking mechanism includes four locking pins and is arranged in an array around the lock holes 11 in the cabinet 1. The locking pins 21 have limiting holes 22 that match the locking pins.

[0023] The locking pin includes an electromagnet 3, a spring element 31, and a pin head 32. The cabinet body 1 has a stepped cavity 12 that communicates with the lock hole 11. The electromagnet 3 is located in the stepped cavity 12 on the side away from the lock hole 11. The spring element 31 is connected to the electromagnet 3. The pin head 32 is connected to the other end of the spring element 31 and extends into the lock hole 11. The side of the pin head 32 facing the opening of the lock hole 11 is inclined and matches the limiting hole 22 of the locking pin 21.

[0024] When installing the charging pile and this device, first connect the cabinet 1 to the external support such as the wall with bolts, then connect the charging pile to the carrier plate 2 to form a pre-assembled unit, and finally connect the carrier plate 2 to the cabinet 1 through the locking mechanism to complete the connection between the charging pile and the cabinet 1. Since the bolt points connecting the cabinet 1 to the wall and the bolt connection points between the charging pile itself and the carrier plate 2 are all covered by the carrier plate 2, external personnel cannot directly remove the cabinet 1 or the charging pile from the side of the cabinet 1 or from inside the cabinet 1, which makes the device safer.

[0025] When the carrier plate 2 is connected and fixed to the cabinet 1 by the locking mechanism, simply align the locking pin 21 on the carrier plate 2 with the lock hole 11 of the cabinet 1 and insert it until the limiting hole 22 of the locking pin 21 is connected with the pin head 32 of the locking pin. This will restrict the displacement of the carrier plate 2 and prevent it from sliding back and forth. Since the elastic element 31 generates a static thrust on the pin head 32, it can push the pin head 32 to move to the side of the locking pin 21 in a static state, maintaining the real-time limiting position. The inclined surface of the pin head 32 can ensure smooth connection between the pin head 32 and the locking pin 21 when inserted, and ensure that it cannot be displaced when the limiting position is reached.

[0026] During daily use, due to the installation and distribution of the carrier plate 2, the prerequisite for removing the charging pile and cabinet 1 is to first release the connection between the locking mechanism and cabinet 1. When this is necessary, the electromagnet 3 can be powered through the control panel inside cabinet 1. The control panel is a common single-chip microcontroller, mainly used to control the circuit on / off and current switching, and for subsequent cabinet status monitoring. The pin 32 itself is made of a magnetic positive or negative magnet, so the magnetic pole of electromagnet 3 can be adjusted by the direction of the current input to electromagnet 3. When the magnetic poles of the electromagnet 3 and the pin 32 are opposite, an attractive force is generated. At this time, the electromagnet 3 attracts the pin 32 back into the stepped cavity 12, thereby releasing the lock on the locking post 21. This scenario is suitable for authorized personnel to perform normal disassembly and maintenance of the charging pile. When the magnetic poles of the electromagnet 3 and the pin 32 are the same, a repulsive force is generated. Since the position of the electromagnet 3 is fixed, the pin 32 will be forcibly pushed to maintain the limit fixation between it and the locking post 21. This serves as a limit protection for the cabinet 1 after external monitoring sensors such as whether the cabinet door 4 has been forcibly opened or whether the cabinet 1 has been forcibly opened.

[0027] The elastic element 31 is either a spring or a sheet spring.

[0028] The cabinet 1 has a cabinet door 4 on the front side, and a door lock is provided between the cabinet door 4 and the cabinet 1; this can provide initial protection for the front of the cabinet 1 and provide a relatively safe environment for the charging pile.

[0029] The front side of the carrier plate 2 has a double hole 5 that matches the position of the locking pin 21. The diameter of the double hole 5 is smaller than that of the locking pin 21 and it penetrates the locking pin 21. The locking mechanism also includes a magnetic rod that matches the double hole 5. When the electromagnet 3 cannot be powered normally due to damage to the cabinet 1 or the circuit, the magnetic rod can be inserted into the double hole 5. The repulsive force between the magnetic rod and the pin 32, which have the same magnetic poles, will cause the pin 32 to actively retract into the stepped cavity 12 and disengage from the connection between the locking pin and the locking pin 21, thereby achieving the effect of manual unlocking. In order to further improve the locking security, the magnetic poles of the pin 32 in a single locking mechanism can be different and randomly distributed. In this way, even if some external personnel use the same size magnetic rod, they will still be unable to unlock it because the magnetic poles of the magnetic rod are different in different positions, thus playing a further restrictive and protective role.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
