Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement devices, in particular to a connecting mechanism for a commercial vehicle split-box battery replacement device. Background Art

[0002] Commercial vehicles are designed and technically designed to transport people and goods. Industry media report that commercial vehicles utilize battery swapping. This method involves replacing individual power batteries. The vehicle is equipped with multiple, separate power battery packs, typically designed to meet standard specifications, enabling interchangeability.

[0003] At present, power battery boxes are usually installed on commercial vehicle frames through connecting mechanisms. In order to prevent the power battery boxes from accidentally moving, locking parts are usually used to limit the power battery boxes. On the existing connecting mechanism, one locking part usually corresponds to one power battery box. However, when replacing the power battery box, it is usually necessary to replace all the battery boxes on the connecting mechanism, and multiple locking parts need to be operated one by one, which affects the battery replacement efficiency. Based on this, a connecting mechanism for a commercial vehicle split-box battery replacement device is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a connection mechanism for a commercial vehicle split-box battery replacement device to solve the problems raised in the above-mentioned background technology.

[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 connecting mechanism of the commercial vehicle split-box battery replacement device in this embodiment includes a connecting frame 1, and multiple battery compartments 2 are arranged at the upper and lower parts of the front end of the connecting frame 1. The battery compartments 2 are used to place the power battery box. Locking components are installed on the connecting frame 1 between the upper and lower battery compartments 2. The locking components are used to limit the power battery box. Guide plates 4 are installed on both sides of the bottom end of the battery compartment 2. Multiple guide wheels 5 are rotatably connected to the upper end of the guide plate 4. The guide wheels 5 on the guide plate 4 are used to contact the bottom of the power battery box. The guide wheels 5 can support the power battery box and facilitate the sliding movement of the power battery box. Side panels 6 are installed at the upper and lower parts of both ends of the battery compartment 2. The side panels 6 are in contact with both ends of the power battery box. A mounting plate 7 is installed at the rear end of the connecting frame 1 behind the battery compartment 2. The mounting plate 7 is used to connect the frame of the commercial vehicle to achieve the installation of the connecting frame 1.

[0022] Specifically, the locking assembly includes a limiting frame 301, a screw 302, a threaded block 303 and a locking plate 304. A connecting rod 8 is installed on the connecting frame 1 between the upper and lower battery compartments 2. A screw 302 is rotatably connected between the connecting rod 8 and the connecting frame 1. The threaded block 303 is threadedly connected to the surface of the screw 302. The front end of the threaded block 303 is located on the surface of the screw 302 and a locking plate 304 is installed in a sleeve-type manner. The limiting frame 301 is installed on the surface of the connecting frame 1 in front of the screw 302, and limiting plates 9 are installed on the upper and lower sides of the rear end of the limiting frame 301. By rotating the screw 302, the locking plate 304 on the threaded block 303 is driven from a horizontal state to a vertical state. The locking plate 304 in the vertical state can limit the power battery boxes inside the upper and lower adjacent battery compartments 2. During the battery replacement operation, there is no need to operate a large number of locking parts.

[0023] Furthermore, the two limit plates 9 are distributed diagonally, and the locking plate 304 is located between the two limit plates 9. The thickness of the threaded block 303 is greater than the distance between the rear end of the limit plate 9 and the connecting rod 8. When the locking plate 304 contacts the upper limit plate 9, the locking plate 304 is in a vertical state. When the locking plate 304 contacts the lower limit plate 9, the locking plate 304 is in a vertical state. When the locking plate 304 is in use, it is always in contact with one locking plate 304 and will not move to the rear of the limit plate 9, thereby avoiding the situation where the locking plate 304 always follows the rotation shaft 12.

[0024] Furthermore, buffer blocks 10 are installed on both sides of the upper and lower sides of the rear end of the battery compartment 2. The buffer blocks 10 are used to buffer the thrust generated when the power battery box slides in, and at the same time limit the rear end of the power battery box.

[0025] Furthermore, a plurality of mounting grooves 11 are arranged in a linear array on the upper end of the guide plate 4 , and a rotating shaft 12 is rotatably installed inside the mounting groove 11 . The guide wheel 5 is installed on the surface of the rotating shaft 12 , so that the guide wheel 5 can be rotatably connected.

[0026] Furthermore, the front ends of the guide plate 4 and the side plate 6 are both provided with inclined surfaces 13 . The setting of the inclined surfaces 13 serves as a guide for placing the power battery box into the battery compartment 2 .

[0027] When the cam 310 is in the unlocked position, the locking plate 304 is in the unlocked position, and the locking plate 304 is locked in the unlocked position.

[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.
