[0027] The embodiment of the utility model provides an unmanned transport vehicle frame with a puncture-proof tire support device and an unmanned transport vehicle, wherein the unmanned transport vehicle frame with a puncture-proof tire support device comprises a frame body 10, an equipment installation frame 20 and a support device 30;

[0028] The bottom of the frame body 10 is provided with an equipment installation frame 20; the side wall of the equipment installation frame 20 is movably connected to the upper end of the support device 30; the distance of the support device 30 from the ground is less than the distance of the equipment installation frame 20 from the ground;

[0029] When the supporting device 30 encounters an obstacle, it can rotate along the upper end of the supporting device 30 and can rotate to one side of the equipment installation frame 20.

[0030] When implementing it, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the unmanned transport vehicle frame with a burst-proof tire support device includes a frame body 10, an equipment installation frame 20 and a support device 30;

[0032] When the support device 30 is in a free state, the distance between the bottom of the support device 30 and the ground is less than the distance between the equipment installation frame 20 and the ground;

[0033] When encountering an obstacle, the support device 30 can rotate along the connection portion between the upper end of the support device 30 and the equipment installation frame 20, and can rotate to one side of the equipment installation frame 20 to provide the maximum passing space for the obstacle.

[0034] When a tire bursts, the frame body 10 is supported by the support device 30 in a free and vertical state to prevent the vehicle from rolling over.

[0035] The unmanned transport vehicle frame with a puncture-proof tire support device provided by the utility model reduces the leg components by setting the support device 30 on the existing equipment installation frame 20 for installing and accommodating unmanned controllers, brake systems, battery compartments, etc., and replacing the traditional leg structure with the existing equipment installation frame 20, thereby reducing the leg components and greatly reducing the weight of the support device 30; and, through the structure in which the support device 30 is movably connected to the side wall of the equipment installation frame 20, and the design that the support device 30 can be rotated to one side of the equipment installation frame 20 when encountering an obstacle, it can provide the support device 30 with the maximum obstacle avoidance space, which is particularly suitable for the compact frame body 10. The unmanned transport vehicle frame with a puncture-proof tire support device provided by the utility model reduces the leg components and greatly reduces the weight of the support device 30; and, when the support device 30 encounters an obstacle, it can be rotated to the equipment installation frame 20, solving the problem that the existing leg structure cannot be adjusted and is easily blocked or damaged by the obstacle when encountering an obstacle.

[0036] Furthermore, the supporting device 30 is detachably connected to the equipment installation frame 20 .

[0037] In specific implementation, the support device 30 is detachably connected to the equipment mounting frame 20, and the detachable connection includes but is not limited to bolt connection, axle pin connection, etc. Through the detachable structural design of the support device 30, the support device 30 can be conveniently installed and replaced according to the use needs or due to damage.

[0038] Furthermore, the supporting device 30 includes a first bracket 31, an axle pin 32, a second bracket 33 and a bottom plate 34;

[0039] One side of the first bracket 31 is connected to the side wall of the equipment installation frame 20, and the other side is connected to one end of the second bracket 33 through an axle pin 32; the other end of the second bracket 33 is connected to the bottom plate 34; the bottom plate 34 can be parallel to the ground under the action of gravity; when the bottom plate 34 is parallel to the ground, the distance between the bottom plate 34 and the ground is less than the distance of the equipment installation frame 20 from the ground.

[0040] When implementing it, Figure 4 As shown, the support device 30 includes a first bracket 31, an axle pin 32, a second bracket 33 and a bottom plate 34; the first bracket 31 is a U-shaped member; the first bracket 31 is a U-shaped member arranged horizontally; the closed end of the U-shaped member is connected to the side wall of the equipment installation frame 20, and the open end is connected to the second bracket 33 through the axle pin 32;

[0041] The other end of the second bracket 33 is connected to the bottom plate 34; the bottom plate 34 can be parallel to the ground under the action of gravity in a free state; when the bottom plate 34 is parallel to the ground, the distance between the bottom plate 34 and the ground is less than the distance from the ground of the equipment installation frame 20; when a tire blows out, the bottom plate 34 in a free state supports the frame body 10 to prevent rollover.

[0042] In this embodiment, the second bracket 33 and the bottom plate 34 can rotate along the shaft pin 32 when encountering obstacles, and can rotate to one side of the equipment installation frame 20; and the U-shaped structure design of the first bracket 31 can provide the maximum space for the rotation of the second bracket 33 and the bottom plate 34. The overall structure of the support device 30 of this embodiment is light in weight and flexible in rotation, which meets the design requirements of overall lightweight vehicle body.

[0043] In a specific implementation, a gap 311 is provided between the closed end of the U-shaped member and the axle pin 32 , and the gap 311 provides a larger movable space for the second bracket 33 and the bottom plate 34 .

[0044] During specific implementation, the U-shaped opening ends of the first brackets 31 of the plurality of support devices 30 face in the opposite direction to the traveling direction of the vehicle.

[0045] Furthermore, the second bracket 33 is surrounded by two first side plates 331 and two second side plates 332 which are arranged opposite to each other; the upper end of the first side plate 331 is an arc end; the shaft pin 32 passes through the arc end and is connected to the first bracket 31;

[0048] Specific implementation, such as Figure 4 , Figure 5 , Figure 6 As shown, a reinforcing rib plate 334 is provided between the first side plate 331 and the bottom plate 34. The reinforcing rib plate 334 increases the support strength of the first side plate 331 and the connection stability between the first side plate 331 and the bottom plate 34.

[0049] Furthermore, the bottom plate 34 is provided with extension portions 341 extending obliquely upward at both ends along the vehicle traveling direction.

[0050] When implementing it, Figure 4 As shown, the first side plate 331 and the second side plate 332 are both provided with through holes 333. The through holes 333 further reduce the weight of the support device 30 to meet the design requirements of lightweight vehicle body.

[0051] Furthermore, the frame body 10 includes two beams 11 and a plurality of cross beams 12 transversely arranged on the beams 11; the side walls of the equipment mounting frame 20 are provided with a plurality of supporting devices 30; the distance between at least two of the supporting devices 30 perpendicular to the walking direction is greater than the distance between the two beams 11.

Compared with the existing structure in which the legs are installed on the beam 11, the lateral distance between the plurality of support devices 30 can be increased, and the vehicle body structure can be made more stable. When the support device 30 is required to support a tire blowout, the larger lateral support distance can make the support of the support device 30 more stable, thereby further reducing rollover and improving the stability of the support.

[0053] The utility model also provides an unmanned transport vehicle, which adopts any of the unmanned transport vehicle frames with explosion-proof tire support devices as described above.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
