[0028] The present invention is described in detail below in conjunction with specific embodiments. The same or similar reference numerals throughout the embodiments represent the same or similar elements or elements with the same or similar functions. The embodiments are intended to help those skilled in the art further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several improvements or deformations can be made to the present invention, but they still fall within the scope of protection of the present invention.

[0029] Please combine Figure 1 and Figure 2 As shown, the utility model provides a battery pack installation assembly, including a truck beam 1 and a battery pack outer frame 2, wherein the battery pack outer frame 2 is used to carry batteries (not shown). When assembling the battery pack outer frame 2 with the beam 1, it is also necessary to lift the battery pack outer frame 2 upwards through a jacking device to connect and lock it with the beam 1. In this embodiment, the jacking device used is a forklift platform 3.

[0030] Combination Figures 1 to 6As shown, the beam 1 has a mounting platform 102 extending to the side, and a locking device 103 is provided on the mounting platform 102; the side of the beam is also provided with a rough positioning groove 101 extending up and down; and a rotatable locking tongue pressure plate 1031 is provided at the bottom of the locking device 103. In this embodiment, both sides of the beam 1 are provided with mounting platforms 102 extending outward, two mounting platforms 102 on each side, each mounting platform is provided with two groups of bolt holes and a flexible rubber pad 104 is installed at the bottom at the corresponding position, each group of bolt holes fixes a set of locking devices 103, and a total of eight locking devices are installed on the beam 1.

[0031] The battery pack outer frame 2 includes two sub-frames and a connecting frame 206 connecting the bottoms of the two sub-frames; a space for accommodating the beam 1 is formed between the two sub-frames. The battery pack outer frame has a frame locking plate 202 that cooperates with the mounting platform 102 and a coarse positioning key 201 located on the inner side of the sub-frame, the coarse positioning key 201 extends up and down and cooperates with the coarse positioning groove 101; the frame locking plate 202 is provided with a locking hole 2021 that cooperates with the locking device 103.

[0032] The forklift platform 3 is located at the bottom of the battery pack outer frame 2 and is used to lift the battery pack outer frame 2; a forklift coarse positioning column 301 is provided on the upper surface of the forklift platform, and a forklift coarse positioning hole 204 cooperating with the forklift coarse positioning column 301 is provided on the lower surface of the connecting frame 206 of the battery pack outer frame 2; the forklift platform can float in the horizontal direction to a certain extent.

[0033] The mounting platform 102 and the battery pack outer frame 2 are also provided with precision positioning holes 1021 and precision positioning columns 203 that cooperate with each other. In this embodiment, the precision positioning holes 1021 are provided on the mounting platform 102 and the precision positioning columns 203 are provided on the battery pack outer frame 2. If in other embodiments, the precision positioning columns 203 are provided on the mounting platform 102 and the precision positioning holes 1021 are provided on the battery pack outer frame 2, it is also possible, and it will not be repeated here.

[0034] When the beam is docked with the outer frame of the battery pack, the coarse positioning key 201 is inserted into the coarse positioning groove 101 from bottom to top, the fine positioning column 203 is inserted into the fine positioning hole 1021, and the locking tongue pressing plate 1031 passes through the locking hole 2021 and rotates an angle to fix and lock the mounting platform 102 and the frame locking plate 202 to each other. There are multiple options for the locking device 103 with the locking tongue pressing plate 1031 used in this embodiment, such as the locking device with a rotatable locking tongue pressing plate in the announcement number CN116424081B, or other locking devices with a rotatable locking tongue pressing plate in the prior art.

[0035] The utility model also provides a battery swap station, which includes the above battery pack installation assembly.

[0036] Next, the battery pack replacement method in this case is described:

[0037] The two forklift coarse positioning posts 301 on the forklift platform 3 used for carrying the battery pack can cooperate with the two forklift coarse positioning holes 204 at the bottom of the battery pack outer frame 2 to fix the position of the battery pack on the forklift platform 3. When the forklift platform 3 moves under the truck beam 1, the forklift platform 3 rises. While rising, since the forklift platform 3 can float in the horizontal direction to a certain extent, when the coarse positioning key 201 and the coarse positioning groove 101 cannot be completely aligned, the forklift platform 3 can adaptively adjust the horizontal position under the external force of the truck beam 1 and the battery pack outer frame 2 until the coarse positioning key 201 and the coarse positioning groove 101 can be matched one by one. The combination of the coarse positioning key and the groove can largely limit the lateral or longitudinal movement of the battery pack outer frame along the truck beam 1; the forklift platform 3 continues to rise, and the fine positioning column 203 can pass through the fine positioning hole 1021 through the adaptive adjustment of the forklift platform 3; when the frame locking plate 202 on the battery pack outer frame 2 is close to the flexible rubber pad 104, the forklift platform 3 begins to be affected by the reaction force of the truck. If the force reaches the set threshold, the forklift platform 3 stops rising, and the vertical up and down movement of the battery pack outer frame 2 is restricted. At this time, the movement of the battery pack outer frame 2 in three degrees of freedom is restricted, and the positioning and guiding between the battery pack and the truck beam 1 is completed.

[0038] During the process of the forklift platform 3 rising and the battery pack being guided and positioned, the locking tongue pressure plate 1031 of the locking device 103 will pass through the locking hole 2021 on the frame locking plate 202; when the forklift platform 3 stops rising, it will give feedback to the battery swap station, and the battery swap station will send a "lock" signal, and the locking device 1031 will start working. The locking tongue pressure plate 1031 will first rotate 90° in a spiral motion relative to the truck beam 1, and then move vertically upward to press the locking hole 2021 on the frame locking plate 202. Finally, the locking tongue pressure plate 1031 and the locking hole 2021 will contact in a cross shape to fix the battery pack outer frame 2 on the truck beam 1.

[0039] Finally, the truck sends a "locking completed" signal, the forklift platform 3 descends, and the forklift coarse positioning column 301 disengages from the forklift coarse positioning hole 204 on the battery pack outer frame 2. The entire battery pack installation and locking process is completed, and the truck can leave the battery swap station.

[0040] To sum up, the battery replacement device of the present invention has a simple structure and convenient and fast positioning guidance. It includes dual guiding positioning of coarse positioning and fine positioning. The guiding positioning has higher reliability, can improve the replacement efficiency of the battery pack, reduce the user's waiting time, improve the user experience, and save the manufacturing cost of the battery replacement device.

[0041] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary personnel in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications are also within the protection scope of the present invention.
