[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Figures 1 to 4 The front view, back view, exploded view and base structure of a cabinet door lock according to an embodiment of the utility model are respectively shown.

[0026] like Figures 1 to 4 As shown, the cabinet door lock includes a base 1, a groove 3 for accommodating a handle 2 is formed on the base 1, a first movable mechanism 4 is arranged inside the groove 3, the first movable mechanism 4 retracts when the handle 2 is locked, and pops out when the handle 2 is unlocked, the first movable mechanism 4 is connected to a main control board in the cabinet (not shown in the figure), and the main control board in the cabinet is also connected to a power on / off switch in the cabinet (not shown in the figure).

[0027] Among them, the on-off switch in the cabinet is the main switch inside the cabinet that operates under the control of the main control board to power on or off the entire cabinet, which can be a molded case circuit breaker.

[0028] Reference Figure 4 , the first movable mechanism 4 can be cylindrical.

[0029] In the locked state, the handle 2 is located in the groove 3, the first movable mechanism 4 retracts and does not enter the groove 3, and when unlocked, that is, when the handle 2 pops out from the groove 3, the first movable mechanism 4 pops out; in the unlocked state, the handle 2 is located outside the groove 3, the first movable mechanism 4 pops out and can extend into the groove 3, and when locked, that is, when the handle 2 enters the groove 3, the first movable mechanism 4 is compressed by the handle 2 and retracts.

[0030] Specifically, the first movable mechanism 4 is linked with the handle 2, and retracts or pops out according to the movement of the handle 2. The main control board in the cabinet can receive the retraction or pop-up signal of the first movable mechanism 4, and power on the entire cabinet by controlling the power-on / off switch in the cabinet according to the retraction signal, and power off the entire cabinet by controlling the power-on / off switch in the cabinet according to the pop-up signal. The function of automatically powering off the cabinet when the door is opened and unlocked, and automatically powering on the cabinet when the door is closed and locked is realized.

[0031] That is, a first movable mechanism 4 is provided on the door lock base 1, which moves in linkage when the door is opened or closed, and the main control board in the cabinet controls the power on and off in the cabinet according to the specific action, thereby realizing the protection function of automatically cutting off the power in the cabinet when the door is opened and unlocked, and automatically powering on the cabinet when the door is closed and locked.

[0032] It can be understood that according to the standards of electrical cabinets (such as charging piles), some functions are essential for electrical cabinets. For example, a travel switch (hereinafter referred to as SQ) is installed inside the electrical cabinet. The function of this device is to power on and off the electrical cabinet to protect personal safety. When the cabinet door is opened, SQ disconnects, and the main control board inside the cabinet controls the on-off switch inside the cabinet to disconnect, and the power inside the cabinet is cut off. When the cabinet door is closed, SQ closes, and the main control board inside the cabinet controls the on-off switch inside the cabinet to close, and the power inside the cabinet is turned on. Since the sheet metal of the electrical cabinet is not precision sheet metal, sometimes the sheet metal processing tolerance is relatively large, and SQ is relatively sensitive. Therefore, in related technologies, a separately adjustable mounting plate is made for SQ. Before each factory commissioning, the commissioning personnel have to continuously adjust the position of the SQ mounting plate to achieve the protection function of SQ.

[0033] In the present utility model, a first moving mechanism 4 is provided on the cabinet door lock, so that it performs corresponding retracting and ejecting actions when the handle 2 is unlocked and locked, and drives the on-off switch inside the cabinet through the main control board inside the cabinet to automatically cut off the power when the door is opened and unlocked, and automatically turn on the power when the door is closed and locked, realizing the function of SQ. Therefore, there is no need to set SQ and its sheet metal mounting plate inside the cabinet. Therefore, in the present utility model, the cabinet door lock itself plays the role of opening and closing the cabinet door, and at the same time adds the function of SQ to the door lock to realize door opening and closing detection. In this way, SQ and its corresponding sheet metal mounting bracket inside the cabinet can be cancelled, which can not only reduce costs, but also eliminate the need for the commissioning personnel to separately adjust the position of SQ during the factory commissioning of the cabinet, saving labor costs, improving the efficiency of finished products, and reducing costs and increasing efficiency.

[0034] Thus, the cabinet door lock of the embodiment of the present utility model, in combination with the handle and the first moving mechanism, can utilize the door lock to realize door opening and closing detection and the function of turning on and off the power inside the cabinet when the door is opened and closed, and further there is no need to set a door opening and closing travel switch and its mounting plate inside the cabinet, which not only enriches the functions of the cabinet door lock, but also reduces the cost of the cabinet.

[0035] The cabinet door lock is installed on the cabinet door through an installation mechanism. Refer to Figures 1 to 3 , the installation mechanism specifically includes a mounting seat 10, a rotating mechanism 11 and a locking member 12. The mounting seat 10 is fixed on the cabinet door, and the locking member 12 fixes the cabinet door lock on the mounting seat 10.

[0036] It should be noted that in the prior art, the mechanical door lock of the cabinet can only be unlocked or locked manually by a key. There are many types of keys and they are constantly updated. Therefore, the operation and maintenance personnel need to carry different models of door lock keys with them, and sometimes they need to try one by one on site, which has a high time cost and is easy to lose and omit. For this reason, the embodiment of the present utility model proposes a solution that can automatically unlock the cabinet door lock.

[0037] That is, in one example, as Figure 5As shown, a second moving mechanism 5 for retracting or ejecting the handle 2 is provided on the handle 2, and the second moving mechanism 5 is connected to the main control board inside the cabinet. The second moving mechanism 5 can perform retracting and ejecting actions.

[0038] Referring to Figure 3 and Figure 4 , an accommodation space 6 for accommodating the second moving mechanism 5 is formed in the inner wall of the groove 3 ( Figure 3 and Figure 4 show the inner side wall of the groove).

[0039] The cabinet door lock further includes a spring 7 disposed in the groove 3 or on the handle 2 (the spring 7 is shown disposed inside the groove in the figure). The spring 7 is disposed between the handle 2 and the groove 3, and both ends are in contact with the handle 2 and the groove 3 respectively.

[0040] Wherein, the second moving mechanism 5 is a locking tongue for ejecting and retracting the handle 2 according to actual needs. The spring 7 is used to eject the handle 2 when the handle 2 is located in the groove 3 and the second moving mechanism 5 retracts into the handle 2 from the accommodation space 6 to achieve unlocking. When locking, the spring 7 can also be compressed under the compression of the handle 2.

[0041] In the locked state, the handle 2 is located in the groove 3, the second moving mechanism 5 ejects the handle 2 and is located in the accommodation space 6, and the spring 7 is in a compressed state; in the unlocked state, the handle 2 is located outside the groove 3, the second moving mechanism 6 ejects the handle 2, and the spring 7 is in an ejected state.

[0042] Referring to Figure 5 , a keyhole connected to the second moving mechanism 5 is further installed on the handle 2 for opening the door lock with a key.

[0043] Specifically, the second moving mechanism 5 is connected to the main control board inside the cabinet, and can be adjusted to retract or eject the second moving mechanism 5 through the main control board by means of a key, background remote control or Bluetooth, etc., to achieve an automatic unlocking action. That is, when automatic unlocking is required, the operation and maintenance personnel can remotely control in the background or send an instruction to the main control board inside the cabinet via Bluetooth. The main control board adjusts the second moving mechanism 5 to automatically retract the handle 2, and then the spring 7 ejects the handle 2 out of the groove 3 to achieve automatic unlocking.

[0044] Thus, the operation and maintenance personnel do not need to carry a large bunch of keys when going to the site, do not need to try one by one, and do not have to worry about losing or omitting keys. The door lock can be directly commanded to open in the background (remote operation by the staff), or opened with the Bluetooth of a mobile terminal, realizing keyless unlocking.

[0045] In one example, referring to Figure 4The first movable mechanism 4 is arranged in the accommodation space 6. The first movable mechanism 4 and the second movable mechanism 5 are not located in the accommodation space 6 at the same time, and the first movable mechanism 4 retracts under the compression of the second movable mechanism 5.

[0046] In the locked state, the first movable mechanism 4 is compressed and retracted into the base 1 by the second movable mechanism 5, that is, at this time, the first movable mechanism 4 does not enter the accommodating space 5; in the unlocked state, the first movable mechanism 4 pops out from the accommodating space 5 and can extend into (partially or completely enter) the groove 3.

[0047] Specifically, when the door is opened and unlocked, the second movable mechanism 5 (lock tongue) contracts, the spring 7 pops out the handle 2, and then the first movable mechanism 4 (movable cylinder) pops out and enters the groove 3; when the door is closed and locked, the second movable mechanism 5 (lock tongue) extends out and extends into the accommodating space 6, the first movable mechanism 4 (movable cylinder) is compressed and enters the base 1, the handle 2 enters the groove 3 and is locked by the second movable mechanism 5, and the spring 7 is compressed.

[0048] In one example, the cabinet door lock further includes a circuit board (not shown) disposed on the base 1, and the first movable mechanism 4 and the second movable mechanism 5 are respectively connected to the main control board in the cabinet through the circuit board (PCB board).

[0049] Reference Figures 1 to 4 The cabinet door lock further includes an integrated function module 8 disposed on the base 1, and a circuit board (PCB board) is located inside the integrated function module 8. The groove 3 is located on the front side of the base 1, and the integrated function module 8 is located on the back side of the base 1.

[0050] like Figure 6 As shown, the integrated functional module 8 also includes a connector 81, and the connector 81 is respectively connected to the circuit board and the main control board in the cabinet.

[0051] The integrated function module 8 also has a built-in backup battery (not shown in the figure). When the whole cabinet is out of power or fails, the cabinet door lock is powered by the backup battery.

[0052] The integrated function module 8 is mainly composed of a PCB circuit board, a backup battery (rechargeable and dischargeable) and a connector 81. The PCB board can include a tipping detection function and a door lock detection function (i.e., a travel switch function). The integrated function module 8 integrates the power lines and communication lines together and outputs them through the connector 81. The main control board in the cabinet is connected to the connector 81 of the cabinet door lock to realize the above functions.

[0053] The tilting detection function refers to detecting whether the cabinet, such as a charging pile, is installed horizontally. When the tilting angle is relatively large, an alarm will be triggered. At the same time, when the cabinet is damaged by an external object impact, such as being hit by an electric vehicle, resulting in cabinet deformation, an alarm will also be triggered, etc. By installing the tilting detection function on the cabinet door lock, the tilting switch and the tilting switch mounting plate in the cabinet can be eliminated, further reducing the overall cabinet cost.

[0054] By integrating the functional module 8, other functions can be expanded according to actual needs, such as the necessary functions of different types of cabinets, etc. It can not only realize a multi-functional cabinet door lock but also reduce the cabinet cost.

[0055] As Figure 7 shown, a charging interface 9 is also provided on the base 1. The charging interface 9 can be set at the bottom of the base 1. When the cabinet door lock fails, the backup battery runs out of power, or there is a power outage, it can be connected to an external power bank through the charging interface 9, and unlocking can be achieved by charging with the power bank.

[0056] In summary, the cabinet door lock of the embodiment of the present invention retains the mechanical switch function, has a keyless automatic unlocking function, and also has the necessary functions of the cabinet, such as a travel switch function, a tilting detection function, etc. It combines multiple functions into one, meets the diverse requirements of the door lock function, and reduces costs and increases efficiency; it realizes intelligent operation and maintenance, keyless door opening, improves the convenience of operation and maintenance, solves the problem of numerous and indistinguishable door lock keys, and meets the requirement of keyless door opening.

[0057] The embodiment of the present invention also proposes a charging pile, including the cabinet door lock proposed in the above embodiment.

[0058] Through the above solution, a multi-functional door lock for the charging pile is realized: retaining the mechanical door lock function and adding a keyless unlocking function; adding a protection function for the travel switch of the charging pile and a tilting detection function; considering the power failure of the charging pile and adding a backup battery; considering the exhaustion of the backup battery power and adding a charging interface.

[0059] Thus, in combination with the handle and the first moving mechanism, the door lock can be used to realize the detection of door opening and closing and the function of power on and off inside the cabinet when opening and closing the door. Furthermore, there is no need to set a door opening and closing travel switch and its mounting plate inside the cabinet, reducing the cost.
