[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figure 1-6 As shown, this embodiment provides a door lock device for locking between a side door 10 and a fixed structure. The door lock device includes a support member 1, a locking rod 2, and a latch 3. The support member 1 is assembled on the side door 10, and the locking rod 2 is hinged to the support member 1. When locked, the support member 1 and the locking rod 2 pass through the fixed structure, the locking rod 2 deflects to a vertical state, and the latch 3 is vertically inserted between the locking rod 2 and the fixed structure to fix the position of the locking rod 2 and achieve locking.

[0034] The support member 1 is horizontally mounted on the side door 10. The first end of the support member 1 is mounted on the side door 10, and the second end of the support member 1 can be used to mount the locking rod 2. Specifically, the support member 1 includes two support seats 11, which are parallel and spaced apart. The middle position of the two support seats 11 is used to mount the locking rod 2.

[0035] As a preferred technical solution in this embodiment, the two support seats 11 can be assembled perpendicular to the inner surface of the side door 10.

[0036] As a preferred technical solution in this embodiment, the fixing device is provided with a through hole. When the side door 10 moves toward the fixing device, the two support seats 11 can pass through the through hole, and the second ends of the two support seats 11 can pass through and extend out of the through hole. That is, the length of the support seat 11 is greater than the length of the through hole.

[0037] As a preferred technical solution in this embodiment, in order to facilitate the installation of a handle portion 12 on the push-pull support member 1, the handle portion 12 can be installed at the end face of the second end of a support base 11.

[0038] The locking rod 2 is hinged to the second end of the support member 1. Specifically, the locking rod 2 is located between the two support seats 11 and is hinged to the support seats 11 via the rotating shaft 5. A retaining ring is provided on the rotating shaft 5 to limit the axial position.

[0039] As a preferred technical solution in this embodiment, the locking rod 2 is cuboid in shape, and the distances from the two ends of the locking rod 2 to the rotating shaft 5 are different, with the distance from one end of the locking rod 2 to the rotating shaft 5 being greater than the distance from the other end of the locking rod 2 to the rotating shaft 5.

[0040] The locking rod 2 remains horizontal under the action of the elastic element 4. One end of the elastic element 4 is connected to the side door 10, and the other end of the elastic element 4 is connected to one end of the locking rod 2. The connection point between the elastic element 4 and the side door 10 is basically at the same height as the hinge position of the locking rod 2. In the initial state, the elastic element 4 is in a slightly stretched state, which can hold one end of the locking rod 2, keeping the locking rod 2 horizontal and facilitating its passage through the through hole in the fixed structure.

[0041] As a preferred technical solution in this embodiment, the elastic element 4 may be, but is not limited to, a spring. The elastic element 4 is located between the two support seats 11.

[0042] As a preferred technical solution in this embodiment, the elastic element 4 is connected to the end of the locking rod 2 that is closer to the rotation axis 5, which can reduce the space required for the locking rod 2 to deflect from the horizontal state to the vertical state and avoid interference with the fixed structure.

[0043] When locked, rotating the locking rod 2 to a vertical position causes the locking tongue 3 to maintain the vertical position of the locking rod 2. Specifically, the end of the locking rod 2 connected to the elastic element 4 deflects upward, and the through hole of the fixed structure provides deflection space for the locking rod 2 to deflect upward. The end of the locking rod 2 away from the elastic element 4 deflects downward, which can form a lock with the fixed structure. The locking tongue 3 is vertically inserted between the locking rod 2 and the fixed structure, which can keep the locking rod 2 in a vertical position.

[0044] As a preferred technical solution in this embodiment, the insertion end of the locking tongue 3 is formed with a relief groove 32. When inserted, the elastic member 4 can be placed in the relief groove 32 without affecting the operation of the elastic member 4. The relief groove 32 is a U-shaped groove with the opening facing downward. The lower end of the locking tongue 3 is inserted between the locking rod 2 and the fixing structure, blocking the end of the locking rod 2 connected to the elastic member 4, preventing it from deflecting downward, and thus maintaining a vertical state.

[0045] As a preferred technical solution in this embodiment, a handle structure 31 is formed at the upper end of the locking tongue 3, which facilitates gripping the locking tongue 3 for insertion and removal.

[0046] This embodiment also provides a charging pile, including a pile body 20 and a side door 10. The side door 10 is mounted on the pile body 20 and locked to the pile body 20 by the aforementioned door lock device. Specifically, one end of the side door 10 is hinged to the pile body 20, and the other end of the side door 10 is locked to the pile body 20 by the door lock device.

[0047] As a preferred technical solution in this embodiment, the pile body 20 serves as a fixed structure, facilitating the locking of the side door 10. The pile body 20 includes a fixed column 201, and the side door 10 is locked to the fixed column 201 by a door lock device. More preferably, a through hole is formed on the fixed column 201, allowing the support member 1 and the locking rod 2 to pass through the through hole when the side door 10 is closed. Furthermore, the end of the locking rod 2 connected to the elastic member 4 can be deflected upwards to a vertical state, facilitating locking.

[0048] Based on the above structure, the charging pile in this embodiment can conceal the door lock of the side door 10, reducing the sheet metal depth. The specific operation process is as follows:

[0049] First, in the unlocked state, the bolt 3 is pulled out. Due to the tension of the elastic element 4, the locking rod 2 is naturally stretched to a horizontal state, which facilitates the normal opening and closing of the side door 10 through the fixed column 201.

[0050] Then, after the door lock device passes through the fixed column 201, the maintenance personnel apply downward pressure to the locking rod 2, so that the locking rod 2 changes to a vertical downward state; at this time, the handle part 12 on the support base 11 applies an inward pulling force to the side door 10, so that the closing angle of the side door 10 meets the locking conditions.

[0051] Finally, the maintenance personnel insert the latch 3 into the inside of the fixed column 201, so that the locking rod 2 and the latch 3 fit tightly together, thus completing the locking of the side door 10.

[0052] The above implementation method can be repeated by opening and closing the device again.

[0053] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing" and other such terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two modules or the interaction between two modules.
