Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, an AGV steering wheel transport vehicle in one embodiment of the present invention includes: a vehicle body 1, a steering wheel assembly 2, and a shock absorbing and buffering component 3.

[0032] like Figures 1 to 2 As shown, a battery 101 is mounted on the top of the vehicle body 1. The battery 101 provides electrical energy for the AGV steering wheel transporter.

[0033] like Figures 1 to 2 As shown, auxiliary wheels 102 are fixedly mounted below the vehicle body 1. The auxiliary wheels 102 support and limit the vehicle body 1 and assist in its movement.

[0034] like Figures 3 and 4 As shown, the steering wheel assembly 2 is assembled below the vehicle body 1. The steering wheel assembly 2 includes a pair of steering wheel plates 201. The pair of steering wheel plates 201 are assembled below the vehicle body 1 along a diagonal direction. The steering wheel plates 201 play a role in assembling and fixing the wheel frame 203.

[0035] like Figures 3 to 7 As shown, a pair of steering wheel plates 201 are fixedly connected to the top of each of the steering gears 202. By driving and controlling the steering gears 202, the moving angle of the running wheels 204 is adjusted, so that the vehicle body 1 can move in multiple directions.

[0036] like Figures 3 and 4 As shown, a pair of steering wheel plates 201 are fixedly connected to the bottom of the wheel frame 203. The wheel frame 203 plays the role of assembly limit for the running wheel 204.

[0037] like Figures 3 and 4 As shown, a drive motor 206 is mounted on one side of the wheel frame 203, and the drive motor 206 is in transmission connection with the running wheel 204. The running wheel 204 is rotationally driven by controlling the operation of the drive motor 206, so that the vehicle body 1 is supported and moved by the rotation of the running wheel 204.

[0038] like Figures 3 and 4 As shown, a running wheel 204 is rotatably mounted in the wheel frame 203. The running wheel 204 supports and controls the wheel frame 203.

[0039] like Figure 1 As shown, a pair of universal running wheels 205 are assembled below the vehicle body 1, and the pair of universal running wheels 205 are arranged correspondingly to the running wheels 204. The vehicle body 1 is supported and assisted in movement by the universal running wheels 205.

[0040] like Figures 6 and 7 As shown, an adjusting gear 207 is rotatably mounted above the steering wheel plate 201, and the adjusting gear 207 is engaged with the steering gear 202. By controlling the rotation of the adjusting gear 207, the steering gear 202 is rotationally controlled, thereby facilitating the angle adjustment control of the running wheel 204.

[0041] like Figures 6 and 7 As shown, the side of the steering gear 202 away from the adjusting gear 207 is meshed with a matching gear 208. The matching gear 208 plays a role of assisting the rotation drive of the steering gear 202.

[0042] like Figures 6 and 7 As shown, an adjustment motor 209 is fixedly mounted below the steering wheel plate 201, and the output shaft of the adjustment motor 209 is fixedly connected to the adjustment gear 207. The adjustment motor 209 provides power, and the adjustment gear 207 is rotated by controlling the operation of the adjustment motor 209, thereby facilitating the control of the movement angle of the running wheel 204.

[0043] like Figures 6 to 8As shown, a pair of shock-absorbing and buffering assemblies 3 are fixedly assembled between the vehicle body 1 and the steering gear 202. The shock-absorbing and buffering assemblies 3 include multiple sets of assembly rails 301, which are fixedly assembled under the vehicle body 1. The assembly rails 301 are used to assemble and limit the linear slider 302 and guide its sliding.

[0044] like Figures 3 and 4 As shown, a fixed top plate 308 is fixedly mounted above the multiple sets of assembly slide rails 301, and the fixed top plate 308 is fixedly mounted below the vehicle body 1. The multiple sets of assembly slide rails 301 are connected and fixed to the vehicle body 1 through the fixed top plate 308.

[0045] like Figures 6 to 8 As shown, a pair of linear sliders 302 are slidably mounted below the multiple sets of assembly rails 301. The linear sliders 302 slide along the assembly rails 301 to provide a damping sliding space for the vehicle body 1.

[0046] like Figures 4 and 5 As shown, a pair of linear sliders 302 are fixedly connected to slider fixing seats 303 below. The slider fixing seats 303 play the role of assembling, fixing, and shock-absorbing and buffering the linear sliders 302.

[0047] like Figures 7 and 8 As shown, a pair of slider fixing seats 303 are hinged with support rods 309 below. The support rods 309 play a role of supporting and limiting the slider fixing seats 303.

[0048] like Figures 7 and 8 As shown, a pin 310 is inserted between the slider fixing seat 303 and the supporting connecting rod 309. The pin 310 connects and limits the slider fixing seat 303 and the supporting connecting rod 309.

[0049] like Figures 7 and 8 As shown, a connecting base 311 is hingedly connected to the bottom of the supporting link 309, and the connecting base 311 is fixedly assembled above the steering gear 202. The supporting link 309 and the steering gear 202 are assembled and limited by the connecting base 311.

[0050] like Figures 4 and 5 As shown, a pair of slider fixing seats 303 are fixedly connected to the opposite sides thereof with a guide slide bar 304. The slider fixing seats 303 are guided to move by the guide slide bar 304 sliding in the limit plate 305.

[0051] like Figures 4 and 5As shown, a limit plate 305 is inserted into the end of the guide rod 304 away from the slider fixing seat 303. The limit plate 305 is fixedly mounted below the vehicle body 1. The limit plate 305 and the slider fixing seat 303 are used to position the damping spring 307. This facilitates the support and position of the slider fixing seat 303 by the contraction and return of the damping spring 307.

[0052] like Figures 4 and 5 As shown, a buffer airbag 306 is fixedly connected between the slider fixing seat 303 and the limiting plate 305. The buffer airbag 306 plays a role of buffering and limiting the slider fixing seat 303.

[0053] like Figures 4 and 5 As shown, a shock absorbing spring 307 is arranged inside the buffer airbag 306, and the shock absorbing spring 307 is sleeved on the outside of the guide slide bar 304. The slider fixing seat 303 is supported and limited by the contraction and reset of the shock absorbing spring 307.

[0054] Specifically, a plurality of evenly distributed damping exhaust holes are provided on the outside of the buffer airbag 306. The damping exhaust holes are used to discharge the gas in the buffer airbag 306 so as to buffer and limit the slider fixing seat 303.

[0055] It is worth noting that the outer diameter of the damping exhaust holes is smaller than the inner diameter. By setting the inner and outer diameters of the damping exhaust holes, the airbag 306 can exhaust air at a faster speed than the air intake during the exhaust process, thereby damping and limiting the slider fixing seat 303 and the limiting plate 305 through the airbag 306.

[0056] In specific use, the driving motor 206 can be controlled to drive the running wheels 204 to rotate, and the running wheels 204, the universal running wheels 205 and the auxiliary wheels 102 cooperate with each other to support and move the vehicle body 1. At the same time, the adjusting motor 209 can be controlled to drive the adjusting gear 207 to rotate, and the adjusting gear 207 and the steering gear 202 can be meshed to adjust the angle of the steering wheel plate 201, thereby facilitating the adjustment of the moving angle of the running wheels 204.

[0057] When the vehicle body 1 is bumpy during movement, the linear slider 302 can slide along the assembly slide rail 301 to compress the slider fixing seat 303 on the shock-absorbing spring 307. The slider fixing seat 303 can squeeze the buffer airbag 306 during movement, and the air in the buffer airbag 306 can be discharged through the damping exhaust hole to buffer and limit the slider fixing seat 303, thereby facilitating shock absorption and buffering of the steering wheel plate 201 and the vehicle body 1, thereby improving the operating stability of the vehicle body 1.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0059] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
