[0017] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention is as follows: a rescue vehicle with adjustable center of gravity, comprising a bottom plate 1, a transmission box 3 is fixedly connected to the left and right sides of the bottom plate 1, a plurality of rotating wheels 4 are fixedly connected to the opposite sides of the two transmission boxes 3, the outer walls of the plurality of rotating wheels 4 are meshed and connected with corresponding transmission belts 5, a working plate 6 is arranged on the top of the bottom plate 1, a groove 7 is provided on the top of the two transmission boxes 3, a moving block 8 is slidably connected to the two inner ends of the two grooves 7, a rotating shaft 9 is fixedly connected to the top of the two moving blocks 8, a groove 2 10 is provided on the left and right sides of the bottom of the working plate 6, a telescopic rod 11 is fixedly connected to the two inner ends of the two grooves 10 , the adjacent ends of the two telescopic rods 11 are fixedly connected with a moving block 2 12, and the bottoms of the multiple moving blocks 2 12 are fixedly connected with a rotating shaft 2 13, and the two rotating shafts 1 9 and one side of the rotating shaft 2 13 are rotatably connected with corresponding connecting plates 14 and 15, and the top of the connecting plate 2 15 is provided with a sliding groove 16, and the connecting plate 1 14 passes through the sliding groove 16, and the top of the working plate 6 is provided with a car body 17, and the top of the bottom plate 1 is provided with a rotating mechanism 2, and the rotating mechanism 2 is used to rotate the car body 17, and the multiple moving blocks 2 12 slide in the corresponding grooves 2 10 respectively, and the size of the moving blocks 2 12 is consistent with that of the grooves 2 10; Specifically, the telescopic rod 11 pushes the moving block 2 12 to move to the middle position. During this process, the rotating shaft 2 13 starts to rotate, thereby driving the connecting plate 1 14 and the connecting plate 2 15 to rotate accordingly, and the moving block 1 8 will also move accordingly, thereby causing the rotating shaft 1 9 to rotate. As the rotation continues, the connecting plate 1 14 and the connecting plate 2 15 gradually assume a vertical state, and the center of gravity of the vehicle body 17 can be adjusted to adapt to various rescue environments.

[0019] Reference Figure 4 and Figure 5 The rotating mechanism 2 includes a rotating groove 201, which is opened at the bottom of the vehicle body 17. The bottom of the working plate 6 is fixedly connected with a motor 202. The output end of the motor 202 penetrates the working plate 6 and is fixedly connected with a rotating rod 1 203. The top of the rotating rod 1 203 is fixedly connected with a driving gear 204. The front and rear sides of the top of the working plate 6 are both rotatably connected with rotating rods 205. The tops of the two rotating rods 205 are fixedly connected with driven gears 206. The two driven gears 206 are respectively meshed with the front and rear sides of the driving gear 204. The inner wall of the rotating groove 201 is fixedly connected with a gear ring 207. Specifically, the motor 202 is started, and the output end of the motor 202 drives the rotating rod 1 203 to rotate, and the driving gear 204 at the top of the rotating rod 1 203 rotates accordingly. The rotation of the driving gear 204 drives the driven gears 206 on both sides thereof to rotate, and the rotation of the driven gear 206 causes the rotating rod 205 to rotate on the top of the working plate 6. Since a gear ring 207 is fixed to the inner wall of the rotating groove 201 at the bottom of the vehicle body 17, and the driven gear 206 interacts with the gear ring 207, the vehicle body 17 can rotate on the working plate 6 under the rotation of the driven gear 206 and the meshing with the gear ring 207.

[0020] Reference Figure 1 and Figure 2 , both ends of the adjacent sides of the two transmission boxes 3 are fixedly connected with a fixing plate 18, the tops of the multiple fixing plates 18 are fixedly connected with a hydraulic rod 19, the tops of the multiple hydraulic rods 19 are fixedly connected to the bottom of the working plate 6, the bottoms of the multiple fixing plates 18 are fixedly connected with a triangular plate 20, one side of the multiple triangular plates 20 is fixedly connected to one side of the corresponding transmission box 3, and the left and right sides of the vehicle body 17 are fixedly connected with a fender 21, and the fender 21 is used to prevent mud and water from splashing; Specifically, the fixing plate 18 supports the hydraulic rod 19, and the hydraulic rod 19 assists in lifting the vehicle body 17. The triangular plate 20 can strengthen the stability of the fixing plate 18 to make it more fixed, and the mud guard 21 can prevent splashing of mud and water.

[0021] Reference Figure 3 and Figure 4A circular groove 22 is formed at the bottom of the vehicle body 17, and a plurality of rollers 23 are rotatably connected to the inside of the circular groove 22 at equal intervals. Slide grooves 24 are formed on the left and right sides of the two grooves 7, and a plurality of sliders 25 are fixedly connected to the left and right sides of the plurality of moving blocks 8, and the plurality of sliders 25 slide in the corresponding slide grooves 24 respectively; Specifically, the circular groove 22 and the roller 23 can make the vehicle body 17 rotate more smoothly, and the slider 25 and the slide groove 24 can make the moving block 8 more stable when moving.

[0022] Working principle: When using a rescue vehicle with adjustable center of gravity, the transmission boxes 3 on the left and right sides of the bottom plate 1 cooperate with the corresponding transmission belts 5 through the multiple rotating wheels 4 on the outside thereof to realize the movement function of the rescue vehicle. When the center of gravity needs to be adjusted, it is achieved by changing the position of the moving block 1 8 in the groove 1 7 and the position of the moving block 2 12 in the groove 2 10. The moving block 2 12 moves in the groove 2 10 under the action of the telescopic rod 11, the rotating shaft 1 9 moves with the moving block 1 8, and the rotating shaft 2 13 moves with the moving block 2 12. Then, the connecting plate 1 14 and the connecting plate 2 15 rotate and relatively displace under the rotation of the rotating shaft 1 9 and the rotating shaft 2 13. The connecting plate 1 14 penetrates the sliding groove 16 on the top of the connecting plate 2 15, so that the two can slide relative to each other, thereby adjusting the angle and height between the working plate 6 and the bottom plate 1. The body 17 on the top of the working plate 6 changes the center of gravity position as the position of the working plate 6 changes. The center of gravity of the rescue vehicle can be flexibly adjusted according to actual needs to better adapt to complex terrain and rescue mission requirements. When the direction of the vehicle body 17 needs to be adjusted, the motor 202 is started, and the output end of the motor 202 drives the rotating rod 1 203 to rotate, and the driving gear 204 at the top of the rotating rod 1 203 rotates accordingly. The rotation of the driving gear 204 will drive the driven gears 206 on both sides to rotate, and the rotation of the driven gear 206 causes the rotating rod 205 to rotate on the top of the working plate 6. Since a gear ring 207 is fixed to the inner wall of the rotating groove 201 at the bottom of the vehicle body 17, and the driven gear 206 interacts with the gear ring 207, the vehicle body 17 can be rotated on the working plate 6 under the rotation of the driven gear 206 and the meshing with the gear ring 207, thereby realizing the adjustment of the direction of the rescue vehicle body 17, so as to better adapt to different rescue scenes and task requirements.

[0023] 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, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
