[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 4 As shown, the locking mechanism of the commercial vehicle sub-box battery swapping device of this embodiment includes a battery swapping frame 1. Several battery compartments 2 are provided on the upper and lower parts of the battery swapping frame 1. The battery compartment 2 is used to place the power battery box. A connecting frame 3 is installed between the upper and lower battery compartments 2. A mounting plate 1 4 is installed at the front end of the connecting frame 3. A mounting plate 2 5 is installed on the battery swapping frame 1 in front of the mounting plate 1 4. A rotating screw 6 is rotatably connected between the mounting plate 1 4 and the mounting plate 2 5. A threaded block 7 is threadedly connected to the surface of the rotating screw 6. A locking plate 8 is installed at the front end of the threaded block 7. By rotating the rotating screw 6 It drives the threaded block 7 to move, and the threaded block 7 drives the locking plate 8 to move. When the locking plate 8 moves, it changes from a horizontal state to a vertical state, thereby locking the power battery box and preventing the power battery box from accidentally moving inside the battery compartment 2. A limit frame 9 is installed on the battery exchange frame 1 in front of the locking plate 8, and limit plates 11 are respectively installed above and below the rear end of the limit frame 9. The two limit plates 11 adjust the horizontal and vertical states of the locking plate 8. An adjustment groove 10 is provided on the surface of the rotating screw 6, and the adjustment groove 10 is used to rotate the rotating screw 6 using a tool.

[0022] Specifically, the limit frame 9 is sleeved on the front end of the battery exchange frame 1. The limit frame 9 is rectangular, and the two limit plates 11 are diagonally distributed. The locking plate 8 is located between the two limit plates 11, and the thickness of the threaded block 7 is greater than the distance between the rear end of the limit plate 11 and the connecting frame 3. When one end of the locking plate 8 contacts the upper limit plate 11, the locking plate 8 is in a vertical state, thereby locking the power battery box. When one end of the locking plate 8 contacts the lower limit plate 11, the locking plate 8 is in a horizontal state, releasing the lock on the power battery box, and the locking plate 8 will not move to the rear of the limit plate 11, thereby preventing the locking plate 8 from rotating with the rotating screw 6 and losing the locking effect.

[0023] Furthermore, a through hole is provided on the surface of the locking plate 8, and the rotating screw 6 is located inside the through hole. Contact pads 12 are installed on the surface of the locking plate 8 above and below the through hole. The locking plate 8 body does not contact the rotating screw 6. The contact pad 12 is made of rubber material and plays a protective role, avoiding hard contact between the locking plate 8 and the power battery box, and avoiding scratches on the surface of the power battery box.

[0024] Furthermore, a trigger switch 13 is installed on the connecting frame 3 behind the locking plate 8. When the locking plate 8 moves to a certain position, the trigger switch 13 will be pressed. The trigger switch 13 can send a signal when pressed, and cooperate with the external indicator light to facilitate the prompt that the locking plate 8 has moved to the specified position.

[0025] Furthermore, an adjustment hole 14 is provided at the front end of the limit frame 9. The adjustment hole 14 passes through the battery exchange frame 1 and extends to the front end of the rotating screw 6. The setting of the adjustment hole 14 makes it easy to rotate the rotating screw 6 using designated tools.

[0026] Furthermore, a corrugated protective sleeve 15 is installed on the surface of the rotating screw 6 at the front end of the locking plate 8. The front end of the corrugated protective sleeve 15 is connected to the battery exchange frame 1. The corrugated protective sleeve 15 is used to protect the surface of the rotating screw 6 to prevent dust generated during the driving of the commercial vehicle from accumulating on the surface of the rotating screw 6, thereby playing a protective role.

[0027] The method of using this embodiment is as follows: in the initial state, the power battery box is placed inside the battery compartment 2. When the power battery box needs to be locked, the rotating screw 6 is driven to rotate by using a tool. The rotating screw 6 drives the locking plate 8 to move through the threaded block 7. At the same time, the locking plate 8 changes from a horizontal state to a vertical state. The contact pad 12 on the vertical locking plate 8 contacts the power battery box to achieve locking of the power battery box. At the same time, the corrugated protective sleeve 15 protects the surface of the rotating screw 6 to prevent external dust from condensing on the surface of the rotating screw 6. When the power battery box needs to be taken out, the screw 6 can be rotated in the opposite direction.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
