[0026] A vehicle body fixing frame 1, a battery tray 2 is movably provided on the top of the vehicle body fixing frame 1, and a battery module 3 is fixedly provided inside the battery tray 2;

[0027] A shock absorbing assembly is arranged between the vehicle body fixing frame 1 and the battery tray 2, and the shock absorbing assembly is used to reduce the relative vibration between the vehicle body fixing frame 1 and the battery tray 2. The shock absorbing assembly includes a first hinge seat 4 fixedly mounted on the top of the vehicle body fixing frame 1, and the upper and lower ends of the first hinge seat 4 are respectively hinged with hinge arms 5, and the end of the hinge arm 5 away from the first hinge seat 4 is hinged with a second hinge seat 6, and the end of the second hinge seat 6 away from the hinge arm 5 is fixedly mounted with a support plate 7, and a support frame 8 is movably inserted on the surface of the support plate 7, and the support frame 8 is fixedly mounted on one end of the battery tray 2, and a first damping spring 13 is fixedly mounted on one end of the support frame 8. A notch is provided at one end of the battery tray 2 corresponding to the shock absorbing assembly to provide space for the operation of the shock absorbing assembly. There are four hinge arms 5, and the four hinge arms 5 are divided into two groups, four The articulated arms 5 are arranged in parallel, and each group of two articulated arms 5 forms a parallelogram structure with the first articulated seat 4 and the second articulated seat 6. The two groups of articulated arms 5 are arranged vertically up and down, and one end of the opposite surfaces of the two articulated arms 5 in the upper and lower groups is hinged with a telescopic rod 14, and a second damping spring 15 is fixedly installed on the surface of the telescopic rod 14. A movable groove 9 is opened in the middle of the support plate 7, and a guide column 10 is fixedly installed on the inner wall of the support frame 8 corresponding to the position of the movable groove 9. The guide column 10 is movably connected to the inner wall of the movable groove 9 so that the guide column 10 cooperates with the movable groove 9 to guide the movement of the support plate 7. A connecting rod 11 is fixedly installed at one end of the support plate 7 corresponding to the position of the support frame 8, and a spring mounting plate 12 is fixedly installed at the end of the connecting rod 11 away from the position of the support plate 7. The first damping spring 13 is fixedly installed at one end of the spring mounting plate 12 and the opposite surface of the support frame 8, and the spring mounting plate 12 is located on the surface of the connecting rod 11;

[0028] When the above structure is in use, when the battery tray 2 and the vehicle body fixing frame 1 vibrate relative to each other, the battery tray 2 will drive the support plate 7 to move up and down through the support frame 8, and the support plate 7 will drive the second hinge seat 6 to move up and down. Through the mutual cooperation of the first hinge seat 4, the hinge arm 5 and the second hinge seat 6, when the support plate 7 moves up and down, the support plate 7 will also move to a certain extent in the horizontal direction, and the support plate 7 and the support frame 8 will move relative to each other, and the first damping spring 13 is squeezed and stretched through the connecting rod 11 and the spring mounting plate 12, so that the first damping spring 13 can buffer the movement of the support plate 7 and the support frame 8 to a certain extent, that is, it plays a buffering and protective role for the relative vibration of the vehicle body fixing frame 1 and the battery tray 2. At the same time, the upper and lower sets of hinged arms 5 will squeeze and stretch the telescopic rods 14 and the telescopic rods 14, so that the elasticity of the second damping spring 15 can buffer the articulation of the hinge arm 5 with the first hinge seat 4 and the second hinge seat 6, that is, it plays a buffering and protective role for the relative vibration of the vehicle body fixing frame 1 and the battery tray 2 again.

[0029] Guide brackets 16 are fixedly installed on the front and rear ends of the battery tray 2, and the inner wall of the guide bracket 16 is movably connected with a mounting bracket 17.

The surface of the battery tray 2 corresponding to the position of the gear 18 is provided with transverse teeth, and the transverse teeth on the surface of the battery tray 2 are meshed with the surface of the gear 18. Damping bearings 19 are rotatably connected to both ends of the central axis of the gear 18, and the damping bearing 19 is fixedly embedded in the middle of the mounting bracket 17. When the vehicle body fixing frame 1 and the battery tray 2 move vertically relative to each other, the teeth on the surface of the battery tray 2 will drive the gear 18 to rotate, and then the gear 18 drives the damping bearing 19 to rotate, and the damping provided by the damping bearing 19 is further hindered to further hinder the frequent relative movement between the vehicle body fixing frame 1 and the battery tray 2, that is, it plays a buffering and protective role against the relative vibration of the vehicle body fixing frame 1 and the battery tray 2.

[0030] Working principle: When in use, the utility model drives the support plate 7 up and down through the support frame 8 when the battery tray 2 and the vehicle body fixing frame 1 vibrate relative to each other. Since the first articulated seat 4 and the second articulated seat 6 cooperate with the two parallelogram structures of the four articulated arms 5 therebetween, when the angle of the first articulated seat 4 is determined, no matter how the articulated arms 5 and the first articulated seat 4 are articulated, the inclination angle of the second articulated seat 6 remains unchanged, that is, when the battery tray 2 drives the support plate 7 up and down through the support frame 8, the support plate 7 drives the second articulated seat 6 to move up and down, and the second articulated seat 6 and the articulated arms 5 are relatively articulated. Since the inclination angle of the second articulated seat 6 remains unchanged, the movement of the support plate 7 and the support frame 8 will not be stuck, and the support plate 7 can cooperate with the support frame 8 to The purpose of guiding the relative movement of the vehicle body fixing frame 1 and the battery tray 2 is played. At the same time, through the mutual cooperation of the first hinge seat 4, the hinge arm 5 and the second hinge seat 6, when the support plate 7 moves up and down, the support plate 7 will also move to a certain extent in the horizontal direction, and the support plate 7 and the support frame 8 will move relative to each other, and the first damping spring 13 is squeezed and stretched by the connecting rod 11 and the spring mounting plate 12, so that the first damping spring 13 can buffer the movement of the support plate 7 and the support frame 8 to a certain extent, that is, it plays a buffering and protective role for the relative vibration of the vehicle body fixing frame 1 and the battery tray 2. At the same time, by setting the movable groove 9 and the guide column 10, when the support plate 7 and the support frame 8 move relative to each other, the movable groove 9 cooperates with the guide column 10 to guide the relative movement of the support plate 7 and the support frame 8;

[0031] When the support plate 7 moves up and down, the articulated arm 5 is respectively articulated with the first articulated seat 4 and the second articulated seat 6, and the parallelogram formed by the first articulated seat 4, the articulated arm 5 and the second articulated seat 6 changes, that is, the upper and lower sets of articulated arms 5 squeeze and stretch the telescopic rod 14 and the telescopic rod 14, so that the elasticity of the second damping spring 15 buffers the articulation of the articulated arm 5 with the first articulated seat 4 and the second articulated seat 6, that is, the relative vibration of the vehicle body fixing frame 1 and the battery tray 2 is buffered again;

[0032] When the battery tray 2 and the vehicle body mounting frame 1 vibrate relative to each other, the first hinge seat 4, the hinge arm 5, the second hinge seat 6, the support plate 7 and the support frame 8 in the shock absorbing assembly can guide the relative vibration of the vehicle body mounting frame 1 and the battery tray 2, so that the relative vibration of the vehicle body mounting frame 1 and the battery tray 2 is a vertical up and down vibration, that is, the vehicle body mounting frame 1 and the battery tray 2 will move relative to each other vertically up and down, and the tooth pattern on the surface of the battery tray 2 will drive the gear 18 to rotate, and then the gear 18 drives the damping bearing 19 to rotate, and the damping provided by the damping bearing 19 is used to further hinder the frequent relative movement between the vehicle body mounting frame 1 and the battery tray 2, that is, the relative vibration of the vehicle body mounting frame 1 and the battery tray 2 is buffered and protected, thereby avoiding the battery module 3 inside the battery tray 2 from being damaged due to the relative vibration with the vehicle body mounting frame 1, and further improving the working efficiency of the methanol range-extended electric mining truck;

[0033] By providing the movable groove 9, the guide column 10, the connecting rod 11, the spring mounting plate 12 and the first damping spring 13, the above structure allows the battery tray 2 to move along the direction of the vehicle body fixing frame 1. At the same time, under the action of the first damping spring 13, the movement of the battery tray 2 along the direction of the vehicle body fixing frame 1 is buffered, so that the relative vibration between the vehicle body fixing frame 1 and the battery tray 2 can be further buffered to avoid the battery module 3 inside the battery tray 2 from making hard contact with the vehicle body fixing frame 1. During this process, the tooth pattern on the surface of the battery tray 2 will always mesh with the gear 18, that is, when the battery tray 2 moves along the direction of the vehicle body fixing frame 1, the gear 18 cooperates with the damping bearing 19 to still buffer the relative vibration between the vehicle body fixing frame 1 and the battery tray 2 in the vertical direction.
