Description

TECHNICAL FIELD

[0001] The utility model relates to the field of battery swap cabinet, concretely relates to a lockless maintenance door structure for battery swap cabinet and battery swap cabinet. BACKGROUND

[0002] With the development of electric vehicles, battery swap cabinets for charging batteries are also becoming more and more common. The battery swap cabinet is usually in an unregulated state when it is set in a public area, so it is easy to be stolen for its electrical devices, such as chargers. In addition, in order to maintain the battery swap cabinet, a maintenance door is usually provided on the battery swap cabinet and a lock is provided to prevent the electrical devices inside from being stolen. However, as a theft-prevention measure, the lock is also an obvious target for thieves to damage, i.e., it is known that the maintenance door can be opened by damaging the lock, and the electrical devices inside can be stolen. In addition, some people maliciously damage the lock by blocking the lock hole with chewing gum, making it difficult for maintenance personnel to open it for maintenance. Furthermore, the keys for each battery swap cabinet are different, which requires maintenance personnel to find the corresponding key for each battery swap cabinet every time they maintain the room, and a dedicated person is needed to manage the keys. Therefore, the existing maintenance door structure of the battery swap cabinet needs to be improved. SUMMARY

[0003] The utility model aims at providing a lockless maintenance door structure for a battery swap cabinet.

[0004] To solve the above problems, the technical scheme of the utility model is as follows:

[0010] Further improvement, the sliding limiting groove comprises two oppositely arranged L-shaped limiting plates, and the L-shaped limiting plates are fixed to the inner surface of the maintenance door.

[0011] Further improvement, the clasp ring is upper and lower two.

[0012] A battery replacement cabinet is installed with the above-mentioned lock-free maintenance door structure for battery replacement cabinet

[0013] The utility model discloses the advantages are:

[0014] 1. There is no obvious lock position, thereby avoiding the problem that someone blocks the lock eye to cause the maintenance door to be unable to open.

[0015] 2. There is no sign of padlock position, which can effectively prevent artificial violent damage.

[0016] 3. Disassembly and installation are quick and convenient, and can be disassembled through a magnetic block, without the need for a key and key management. DETAILED DESCRIPTION

[0017] Fig. 1 It is the schematic diagram of the three-dimensional structure of the cabinet body;

[0018] Fig. 2 It is the schematic diagram of the inner side surface structure of the maintenance door;

[0019] Fig. 3 It is the schematic diagram of the three-dimensional structure of the maintenance door. DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the utility model embodiment will be described clearly and completely below.

[0021] As Figs. 1-3 The utility model discloses a kind of lock-free maintenance door structures for battery replacement cabinet, including magnetic attraction piece, cabinet 1, maintenance door 2, limit buckle 3, limit buckle 4, clasp ring 5, sliding limit slot 6, magnetic attraction clamping piece 7, T-shaped limit piece 8, hidden small hole 9 and L-shaped limit plate 10.

[0022] Wherein, cabinet 1 back side opening is arranged, to facilitate push-in maintenance door 2. Cabinet 1 back side other side is installed with limit buckle 3, and the side of maintenance door 2 is formed with the limit buckle 4 that cooperates with limit buckle 3. The opening side of cabinet 1 back is fixed with clasp ring 5, and the inner surface of maintenance door 2 is fixed with sliding limit slot 6, and sliding limit slot 6 is slidably connected with n-shaped magnetic attraction clamping piece 7, and the inner side bottom of magnetic attraction clamping piece 7 is fixed with T-shaped limit piece 8, and T-shaped limit piece 8 is provided with hidden small hole 9 directly below.

[0023] When installing, the magnetic member is attracted to the outer side of the maintenance door 2, and the magnetic clamping member 7 is attracted so that the magnetic clamping member 7 is in the raised position and avoids interference with the clamping ring 5. Then the maintenance door 2 is pushed so that the limiting buckle 3 is inserted into the limiting slot 4, and the front and back positioning of the maintenance door 2 is completed. Then the magnetic member is removed, and the n-shaped magnetic clamping member 7 is affected by gravity and slides downward, and is inserted into the clamping ring 5 to form the left and right direction limiting, that is, the installation of the maintenance door 2 is completed.
