[0024] 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.

[0025] The utility model provides Figure 1-6 The chassis frame 1 shown in FIG. 1 has a battery box 103 disposed on the top of the chassis frame 1 and further includes

[0026] The locking mechanism is provided at the connection between the chassis frame 1 and the battery box 103. The locking mechanism includes a positioning column 2, a pneumatic block 201 and a pneumatic locking pin 202. A plurality of pneumatic blocks 201 are provided on the outer walls of the plurality of positioning columns 2.

[0027] A positioning device is provided at the top edge of the chassis frame 1 and is used to fix the position of the battery box 103;

[0028] The locking mechanism is arranged on the outer wall of the battery box 103 and is used to fix the position of the battery box 103 .

[0029] It should be noted that when installing the battery box 103, the middle of the bottom needs to be aligned with the connecting socket 101 at the top of the chassis frame 1, and the battery needs to be lifted up using the lifting equipment of the battery swap station to replace the new battery box 103. When replacing, the bottom end of the battery box 103 needs to be positioned on the inner wall of the positioning panel 3, and stable installation can be achieved under the positioning of the positioning column 2. The pneumatic block 201 of the positioning column 2 will eject the pneumatic locking pin 202 through the bottom end of the battery box 103 to achieve fixation.

[0030] Specifically, a connecting plate 102 is provided in the middle of the top of the chassis frame 1, a connecting socket 101 is provided at the top of the connecting plate 102, a plurality of pneumatic locking pins 202 are provided on the outer walls of a plurality of positioning columns 2 and are located at one end away from the pneumatic block 201, and a chamfered block 203 is provided at the top of the positioning column 2.

[0031] It should be noted that the connecting plate 102 and the connecting socket 101 are the battery connecting holes of the heavy truck. A connecting socket is provided at the bottom end of the battery box 103. When the battery box 103 is dropped for installation, it is necessary to electrically connect the socket end of the battery box 103 to the connecting socket 101. The chamfered block 203 of the positioning column 2 can calibrate the bottom position of the battery box 103 when the battery box 103 falls. At the same time, when the battery box 103 is calibrated and installed, the pneumatic block 201 of the positioning column 2 will eject the pneumatic locking pin 202 to fix the position of the battery box 103.

[0032] Specifically, the positioning device includes a positioning plate 3 and a positioning pin 301. The positioning plate 3 is arranged at the top edge of the chassis frame 1. The positioning pin 301 is arranged at the top of the chassis frame 1 and is located at one end close to the positioning plate 3. A positioning hole 302 is provided at the bottom edge of the battery box 103. The inner wall of the positioning hole 302 is socketed with the outer wall of the positioning pin 301.

[0033] It should be noted that the positioning panel 3 is set at the top edge of the chassis frame 1. When the battery box 103 is installed, the positioning panel 3 can locate the falling point of the battery box 103, and can also limit the installation position of the battery box 103. When the battery box 103 is positioned by the positioning panel 3, the positioning hole 302 at the bottom end of the battery box 103 will be mounted on the outer wall of the positioning pin 301. After the installation is completed, the positioning panel 3 can firmly support the bottom end of the battery box 103.

[0034] Specifically, the blocking mechanism includes a fixed plug 4 and a connecting rod 402. Multiple fixed plugs 4 are arranged at one end of the multiple connecting rods 402 close to the battery box 103. The outer wall of the battery box 103 is horizontally symmetrically provided with multiple fixing holes 401. The outer walls of the multiple connecting rods 402 pass through the positioning panel 3 and are interspersed with the multiple fixing holes 401. Multiple rotating handles 403 are provided at one end of the multiple connecting rods 402 away from the battery box 103.

[0035] It should be noted that circular holes are symmetrically provided on the outer wall of the positioning enclosure 3, and the size of the circular holes is equal to the shape and size of the fixing holes 401. When the battery box 103 is positioned and installed, the positions of the circular holes and the fixing holes 401 correspond to each other. At this time, the fixing plug 4 is passed through the circular hole and the fixing hole 401, and then the operator manually turns the rotating handle 403. The rotating handle 403 drives the fixing plug 4 to rotate ninety degrees through the connecting rod 402. After the end, the fixing plug 4 and the fixing hole 401 will be blocked with each other, so that the fixing plug 4 is fixed on the inner wall of the battery box 103, so that the position between the fixed battery box 103 and the positioning enclosure 3 is fixed.

[0036] Working principle of this utility model:

[0037] The specific operation is that when replacing the battery, the lifting device will lift the new battery box 103, align the middle of the bottom end of the battery box 103 with the connecting socket 101 and drop it for installation. During the falling process, the bottom end of the battery box 103 will be positioned under the guidance of the positioning panel 3 and the positioning column 2, and then slowly dropped to be installed on the top of the chassis frame 1. At the same time, the positioning hole 302 at the bottom end of the battery box 103 will be fitted with the positioning pin 301. Then the operator will insert the fixing block 4 into the fixing hole 401, and the pneumatic block 201 will eject the pneumatic locking pin 202 to lock the position of the battery box 103. Then turn the rotating handle 403, and the rotating handle 403 rotates the rotating handle 403 through the connecting rod 402. At this time, the fixed plug 4 will form a seal with the fixing hole 401, locking the connection between the battery box 103 and the positioning panel 3. During the installation of the battery box 103, this design can use the positioning panel 3 and the positioning column 2 to quickly calibrate and position it. At the same time, after the installation is completed, the positioning panel 3 and the positioning column 2 can also support the bottom position of the battery box 103. The connection position of the battery box 103 is firmly installed through the cooperation of the positioning panel 3 and the fixed plug 4.

[0038] Finally, it should be noted that the above is only 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 can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
