[0040] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0041] In the related art, tracked robots usually have no shock-absorbing structure or mostly use Christie shock-absorbing structure. Christie shock-absorbing structure is an independent suspension device with large-diameter road wheels and coil springs. This suspension is composed of two cylindrical coil springs connected to each other in front and back. The front one is an adjustable horizontal coil spring, and the rear one is a vertical coil spring. This structure causes the tracked robot to vibrate more during driving because there is no shock absorber.

[0042] Combine the following Figures 1 to 9 , describing an embodiment of the utility model.

[0043] According to the embodiments of the present utility model, Figures 1 to 9 As shown, a transport robot is provided, including a vehicle body 1, a suspension mechanism 2 and a walking mechanism 3, the vehicle body 1 is suitable for transporting materials, the suspension mechanism 2 includes at least four frame shock absorbing mechanisms 21 and at least four wheel shock absorbing mechanisms 22, the wheel shock absorbing mechanisms 22 are respectively rotatably connected to the vehicle body 1, the wheel shock absorbing mechanisms 22 are symmetrically arranged on both sides of the vehicle body 1, the frame shock absorbing mechanism 21 is arranged between the vehicle body 1 and the wheel shock absorbing mechanism 22, and at least four walking mechanisms 3 are correspondingly rotatably connected to the wheel shock absorbing mechanisms 22.

[0044] Specifically, in this embodiment, the number of the walking mechanisms 3 is not specifically limited. To conform to the actual situation, in this embodiment, the number of the walking mechanisms 3 is four. Figure 1 , Figure 2 and Figure 6As shown, four walking mechanisms 3 are symmetrically arranged on both sides of the vehicle body 1 in pairs, and each walking mechanism 3 is connected to the wheel set shock absorbing mechanism 22, and the wheel set shock absorbing mechanism 22 is connected to the vehicle body 1. Each walking mechanism 3 adopts a ship-type crawler wheel structure, and each walking mechanism 3 adopts an integrated independent drive. The independent drive has the advantages of high power and high torque density, which improves the load and driving ability of the transport robot. When each walking mechanism 3 is driving, the bumps and impacts on the driving road surface can be absorbed by the wheel set shock absorbing mechanism 22, thereby improving the shock absorption performance of the transport robot. The frame shock absorbing mechanism 21 arranged between the vehicle body 1 and the wheel set shock absorbing mechanism 22 can filter out the high-frequency vibration transmitted to the vehicle body 1 by the walking mechanism 3 during driving, so as to keep the vehicle body 1 stable. In some other embodiments, the walking mechanism 3 can also be set to six or eight or other even numbers according to actual needs.

[0045] The utility model arranges a suspension mechanism 2 between the vehicle body 1 and the traveling mechanism 3, and can provide reliable shock absorption performance when driving on complex roads through the wheel group shock absorbing mechanism 22. The frame shock absorbing mechanism 21 can reduce the frequency of the vehicle body 1 swinging, so that the transport robot can drive more smoothly. The traveling mechanism 3 and the wheel group shock absorbing mechanism 22 are independently connected, so that each traveling mechanism 3 has the characteristics of high degree of freedom of independent upper swing angle and lower swing angle.

[0046] In one embodiment, Figure 2 As shown, the wheel shock absorbing mechanism 22 includes a first buffer component 221 and a swing arm 222, the first buffer component 221 is rotationally connected to the vehicle body 1, the swing arm 222 is rotationally connected to the vehicle body 1, the first buffer component 221 is rotationally connected to the swing arm 222, and the walking mechanism 3 is rotationally connected to the swing arm 222.

[0047] Specifically, in this embodiment, a pin hole is provided in the middle of the swing arm 222, and the swing arm 222 is hinged to the vehicle body 1 through a pin shaft. The first buffer component 221 and the frame shock absorbing mechanism 21 are arranged on both sides of the pin hole, and the walking mechanism 3 is located below the first buffer component 221. The walking mechanism 3 is rotatably connected to the vehicle body 1. When the walking mechanism 3 travels on a complex road surface, the bumpy road surface has an impact on the walking mechanism 3. At this time, the walking mechanism 3 drives the swing arm 222 to rotate around the pin shaft. The first buffer component 221 provides a reverse rotation force to the swing arm 222 to restore the swing arm 222 to its original position, thereby absorbing part of the impact and playing a role in buffering and shock absorbing to stabilize the vehicle body 1. Under the impact of the road surface and the force of the first buffer component 221, the swing arm 222 will produce a relatively high frequency reciprocating swing. The frame shock absorbing mechanism 21 arranged on the other side of the pin shaft can apply a force to the other end of the swing arm 222 to keep the swing arm 222 balanced and reduce the frequency of swinging.

[0048] The utility model connects the walking mechanism 3 with the swing arm 222 through rotation. When the walking mechanism 3 travels on a complex road surface, the walking mechanism 3 drives the swing arm 222 to rotate. The first buffer component 221 can absorb the impact of the buffer part on the vehicle body 1 when the swing arm 222 rotates, thereby reducing the vibration of the vehicle body 1 and making the transport robot travel more smoothly.

[0049] In one embodiment, Figure 2 As shown, the wheel shock absorbing mechanism 22 further includes a first bracket 223, which is rotatably connected to the swing arm 222, and two first buffer components 221 are rotatably connected to the vehicle body 1 at one end and rotatably connected to both ends of the first bracket 223 at the other end.

[0050] Specifically, in this embodiment, the first bracket 223 is rotatably connected to the swing arm 222, one end of the two first buffer components 221 is rotatably connected to the two ends of the top of the first bracket 223 respectively, and the other end of the first buffer component 221 is rotatably connected to the vehicle body 1.

[0051] The utility model respectively arranges a first buffer component 221 at both ends of the first bracket 223. When the walking mechanism 3 travels on a complex road surface, the walking mechanism 3 drives the swing arm 222 to tilt in the direction of travel, and the first buffer component 221 on one side is squeezed, and the first buffer component 221 on the other side is stretched. Correspondingly, when the walking mechanism 3 drives the swing arm 222 to fall in the direction of travel, the first buffer component 221 on one side is stretched, and the first buffer component 221 on the other side is squeezed. The two first buffer components 221 jointly play a buffering role to maintain the stability of the vehicle body 1 and reduce the swinging of the vehicle body 1.

[0052] In one embodiment, Figure 5 As shown, the first buffer assembly 221 includes a piston cylinder 2211, a piston rod 2212 and a first elastic member 2213, one end of the piston cylinder 2211 is rotatably connected to the vehicle body 1, and an opening is provided at the end of the piston cylinder 2211 away from the vehicle body 1, one end of the piston rod 2212 is rotatably connected to the first bracket 223, and the end of the piston rod 2212 away from the first bracket 223 is slidably connected to the piston cylinder 2211, and the first elastic member 2213 is sleeved on the piston cylinder 2211, one end of the first elastic member 2213 is connected to the piston cylinder 2211, and the other end is connected to the piston rod 2212.

[0053] Specifically, in the present embodiment, one end of the piston cylinder 2211 is hinged to the vehicle body 1, and the other end of the piston cylinder 2211 is provided with an opening, one end of the piston rod 2212 is hinged to the first bracket 223, and the other end of the piston rod 2212 is slidably installed in the piston cylinder 2211, and hydraulic oil is provided between the piston cylinder 2211 and the piston rod 2212. When the traveling mechanism 3 travels on a complex road surface, the swing arm 222 swings when the traveling mechanism 3 is impacted, driving the piston rod 2212 to slide in the piston cylinder 2211, and when the piston rod 2212 moves into the piston cylinder 2211, the inner volume of the piston cylinder 2211 is reduced, and the damping effect of the hydraulic oil in the piston cylinder 2211 can slow down the moving speed of the piston rod 2212. At the same time, the first elastic member 2213 outside the piston cylinder 2211 is squeezed, and the first elastic member 2213 can also absorb the force when the swing arm 222 rotates.

[0054] In this embodiment, the first elastic member 2213 is a coil spring.

[0055] The first buffer assembly 221 of the utility model can absorb part of the impact generated by the running of the traveling mechanism 3 under the elastic force of the first elastic member 2213 and the damping effect of the hydraulic oil, so that the vehicle body 1 can be more stable during running.

[0056] In one embodiment, Figure 3 As shown, the frame shock absorbing mechanism 21 includes a first mounting seat 211, a first pull rod 212 and a second elastic member 213. The first mounting seat 211 is rotatably connected to the vehicle body 1. A swing arm 222 at one end of the first pull rod 212 is rotatably connected, and the other end is movably connected to the first mounting seat 211. The second elastic member 213 is sleeved on the first pull rod 212.

[0057] Specifically, in this embodiment, the first mounting seat 211 is hinged to the vehicle body 1, one end of the first pull rod 212 is hinged to the swing arm 222, the first pull rod 212 is provided with an external thread, a nut is installed on the end of the first pull rod 212 close to the swing arm 222, and a baffle is provided on the end of the first pull rod 212 away from the swing arm 222. The second elastic member 213 is sleeved on the pull rod and is located between the baffle and the nut. By adjusting the nut, the elastic force of the second elastic member 213 on the pull rod can be adjusted. A protective cover is provided on the first mounting seat 211, and one end of the first pull rod 212 is located in the protective cover.

[0058] The utility model can reduce the swing frequency of the swing arm 222 through the elastic force of the second elastic member 213, so that the vehicle body 1 is more stable during driving.

A driving wheel is installed on the driving end of the driver 32, and the driving wheel is movably connected to the inner wall of the track 34.

[0065] In this embodiment, the road wheel group 33 is arranged in the direction of travel toward the transport robot. When the walking mechanism 3 travels on a complex road surface, the road wheel group 33 is impacted by the road surface.
