[0036] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0037] An embodiment of the present invention provides a heavy truck battery swapping locking mechanism assembly for connecting a battery box and an electric heavy truck.

[0038] See Figures 1 to 3 , the heavy truck battery swapping locking mechanism assembly includes a battery bracket 1, a positioning and guiding member 2, and a locking mechanism 3. The battery bracket 1 is fixedly connected to the electric heavy truck, and the battery box can be placed on the battery bracket 1; the positioning and guiding member 2 is fixedly connected to the battery bracket 1, and the positioning and guiding member 2 is inserted into the positioning hole of the battery box; the locking mechanism 3 is fixedly connected to the inner side of the edge of the battery bracket 1, and the locking mechanism 3 includes a flipping part 31, and the flipping part 31 can flip to press against the inner wall of the bottom end of the battery box.

[0039] When the battery box is placed on the battery bracket 1, the positioning and guiding member 2 is used to guide and position the battery box, so that the battery box is placed in the correct position on the battery bracket 1. The structure is simple. The locking mechanism 3 is connected to the inner side of the battery bracket 1. Before the battery box is placed on the battery bracket 1, the flipping part 31 is erected so that the flipping part 31 does not interfere with the battery box. After the battery box is placed on the battery bracket 1, the flipping part 31 flips to press against the inner wall of the bottom end of the battery box, thereby realizing the fixation of the battery box. There is no gap between the flipping part 31 and the inner wall of the bottom end of the battery box, and the connection of the battery box is stable and the safety is high.

[0040] See Figure 1, there are at least two and at most eight locking mechanisms 3, which are spaced apart and distributed on the inner side of the edge of the battery bracket 1, achieving stable fixation of the battery box.

[0041] A plurality of second rubber pads 4 are fixedly connected to the battery bracket 1. The plurality of second rubber pads 4 are spaced apart and arranged on the outer edge of the battery bracket 1 to prevent wear between the battery box and the battery bracket 1 during the driving of the electric heavy truck. Second rubber pads 4 are provided at positions corresponding to the flipping parts 31 on the battery bracket 1. The cooperation between the second rubber pads 4 and the flipping parts 31 makes the connection of the battery box closer.

[0042] There are four positioning and guiding members 2, which are located on the inner side of the edge of the battery bracket 1. The four positioning and guiding members 2 enclose a rectangle, achieving the guiding and positioning of the battery box. The number of the positioning and guiding members 2 is the same as the number of the positioning holes of the battery box and they correspond one by one. The positioning and guiding members 2 are positioning and guiding pins.

[0043] The heavy truck battery swapping locking mechanism assembly further includes four quick-change connectors 5, and the quick-change connectors 5 are connected to the battery box.

[0044] See Figure 2 and Figure 3 , the locking mechanism 3 further includes a bottom plate 32, which is fixedly connected to the inner side of the edge of the battery bracket 1, and the bottom plate 32 realizes the support for other components of the locking mechanism 3.

[0045] The locking mechanism 3 further includes a driving member and a connecting base 34. The driving member and the bottom plate 32 are arranged at an angle, and the angle is an acute angle. The driving member includes a cylinder 331 and a cylinder push rod 332. The connecting base 34 connects the cylinder 331 and the rear end of the bottom plate 32. The cylinder push rod 332 can extend and retract, and the driving member provides the flipping power for the flipping part 31.

[0046] The flipping part 31 includes a clamping jaw 311 and a connecting member. The front end of the clamping jaw 311 can press against the inner wall of the bottom end of the battery box. The connecting member connects the clamping jaw 311 and the driving member, and the clamping jaw 311 realizes the clamping and fixation of the battery box.

[0047] The connecting member includes a push rod 3121, a flipping seat 3122, a rotating plate 3123, a rotating rod 3124, a first rotating shaft 3125, a second rotating shaft 3126, a third rotating shaft 3127 and a fourth rotating shaft 3128. The flipping seat 3122 is connected to the front end of the bottom plate 32. The rear end of the push rod 3121 is connected to the front end of the cylinder push rod 332. The first rotating shaft 3125 passes through the rear end of the rotating plate 3123, the rear end of the rotating rod 3124 and the front end of the push rod 3121. The second rotating shaft 3126 passes through the rear end of the jaw 311 and the upper end of the flipping seat 3122. The third rotating shaft 3127 passes through the front end of the rotating rod 3124 and the middle part of the jaw 311. The fourth rotating shaft 3128 passes through the lower end of the flipping seat 3122 and the front end of the rotating plate 3123.

[0048] When it is necessary to clamp the battery box, the flipping part 31 rotates in the A direction towards Figure 2 the inside. The cylinder push rod 332 pushes the push rod 3121 forward. The push rod 3121 pushes the first rotating shaft 3125 forward. The rotating rod 3124 and the rotating plate 3123 move forward and rotate around the first rotating shaft 3125. The whole rotating plate 3123 rotates around the fourth rotating shaft 3128. The rotating rod 3124 drives the third rotating shaft 3127 and the jaw 311 to rotate in the A direction around the second rotating shaft 3126, thereby realizing the flipping of the jaw 311. When the jaw 311 clamps the battery box, the rotating plate 3123 is vertically arranged, and the axes of the first rotating shaft 3125 and the fourth rotating shaft 3128 form a plane perpendicular to the battery bracket 1. When it is necessary to release the battery box, the cylinder push rod 332 contracts to realize the rotation of the jaw 311 in the opposite direction of A.

[0049] A mechanical unlocking hole 35 is provided on the rotating plate 3123. When a failure occurs in the electric heavy truck, the rotating plate 3123 can be pulled backward through the mechanical unlocking hole 35 to release the locking of the flipping part 31, and then the locking mechanism 3 can be opened to remove the battery box.

[0050] The flipping part 31 further includes a first rubber pad 313. The first rubber pad 313 is fixedly connected to the jaw 311 to prevent the jaw 311 from wearing the battery box and increase the friction force, so that the battery box is fixed more firmly.
