DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-5 , further illustrating a specific implementation of a shock absorbing device for an unmanned logistics transport vehicle of the present invention. A shock absorbing device for an unmanned logistics transport vehicle of the present invention is not limited to the description of the following embodiments.

[0026] Embodiment 1:

[0027] This embodiment provides a specific structure of a shock absorbing device for an unmanned logistics transport vehicle, such as Figure 1-5 As shown, the vehicle body 1 includes a vehicle body 1, a running wheel 2 is arranged at the bottom of the vehicle body 1, and universal balancing wheels 3 are arranged at the four corners of the bottom of the vehicle body 1, so that the vehicle body 1 has higher stability during walking, and at least one inner chamber 7 is arranged inside the vehicle body 1, and an inner frame 5 with an opening on the front surface is arranged inside the inner chamber 7, and the inner frame 5 is used to accommodate logistics items;

[0028] Two clamps 8 for clamping and fixing logistics objects are arranged inside the inner frame 5. The clamps 8 are arranged in the vertical direction. The top and bottom of the clamps 8 are respectively engaged with the internal top plate and bottom plate of the inner frame 5. The clamps 8 can move horizontally inside the inner frame 5.

[0029] Connecting tension springs 4 are arranged between the outer wall of the inner frame 5 and the inner wall of the inner sub-chamber 7. There are five groups of connecting tension springs 4 in total. The five groups of connecting tension springs 4 are respectively located on five surfaces of the inner frame 5. Each group of connecting tension springs 4 is provided with several connecting tension springs, and the several connecting tension springs 4 in the same group are distributed in a rectangular array.

[0030] The front surfaces of the two clamping plates 8 are both provided with a card plate 6, and an elastic belt 12 is inserted into the card plate 6. The two ends of the elastic belt 12 are detachably installed with an inverted hanging rod 11, and the length of the inverted hanging rod 11 is greater than the length of the through hole of the card plate 6 through which the elastic belt 12 is inserted.

[0031] By adopting the above technical solution:

[0032] Since the inner sub-chamber 7 is provided with an inner frame 5 with an opening on the front surface, and a plurality of connecting tension springs 4 are provided between the outer wall of the inner frame 5 and the inner wall of the inner sub-chamber 7, such a structural arrangement enables the connecting tension springs 4 to reduce the vibration generated when the vehicle body 1 is subjected to impact and vibration after the logistics items are placed inside the inner frame 5, thereby ensuring the stability of the inner frame 5 and effectively preventing the logistics items inside the inner frame 5 from being transported stably;

[0033] Two clamping plates 8 are arranged inside the inner frame 5, and the clamping plates 8 can move horizontally inside the inner frame 5. Such a structural arrangement enables the two clamping plates 8 to clamp and fix the logistics items when the logistics items are stored inside the inner frame 5, thereby ensuring that the logistics items will not move relative to the inner frame 5 during transportation, thereby effectively preventing the logistics items from colliding with the inner frame 5 during transportation and being damaged;

[0034] The front surfaces of the two splints 8 are each provided with a card plate 6, and an elastic belt 12 is inserted into the card plate 6. In this way, when the vehicle body 1 is braked suddenly, the logistics items in the inner frame 5 will not hit the front door of the vehicle body 1 due to the limitation of the elastic belt 12, thereby further ensuring the integrity and quality of the logistics items.

[0035] Embodiment 2:

[0036] This embodiment provides a specific structure of a shock absorbing device for an unmanned logistics transport vehicle, such as Figure 1-5 As shown, a scissor frame rod 9 is arranged between one side of the clamping plate 8 and the inner side wall of the inner frame 5, and the scissor frame rod 9 is detachably mounted to the inner side wall of the inner frame 5 and the side wall of the clamping plate 8.

[0037] A first slide groove 16 is provided on one side of the clamping plate 8, and a driving slider 15 is mounted inside the first slide groove 16. One end of the scissors frame rod 9 is rotatably mounted on the driving slider 15 through a pin shaft. A second slide groove 17 is provided on the inner side wall of the inner frame 5, and a servo slider 10 is mounted inside the second slide groove 17. The other end of the scissors frame rod 9 is rotatably mounted on the servo slider 10 through a pin shaft.

[0038] A screw rod 20 is arranged inside the first slide groove 16 along the length direction. The screw rod 20 passes through the driving slider 15, and the screw rod 20 and the driving slider 15 are connected through a screw rod kit. A motor 14 is embedded in the surface of the splint 8 at one end of the first slide groove 16, and the output shaft of the motor 14 extends into the first slide groove 16 and is connected to one end of the screw rod 20.

[0039] By adopting the above technical solution:

[0040] A battery for providing power to the motor 14 is also embedded in the clamping plate 8. When the motor 14 is running, it drives the screw rod 20 to rotate. When the screw rod 20 rotates, the driving slider 15 slides inside the first slide groove 16 through the cooperation of the screw rod kit. Due to the structural characteristics of the scissors frame rod 9, when the two driving sliders 15 on the scissors frame rod 9 approach or move away, the scissors frame rod 9 will push the clamping plate 8 to move horizontally, thereby clamping and fixing the logistics parts.

[0041] Embodiment 3:

[0042] This embodiment provides a specific structure of a shock absorbing device for an unmanned logistics transport vehicle, such as Figure 1-5 As shown, the top and bottom of the clamping plate 8 are both provided with limiting slide plates 13 , and the inner top plate and bottom plate of the inner frame 5 are both provided with limiting sliding grooves 18 , and the limiting slide plates 13 are engaged in the limiting sliding grooves 18 .

[0043] The limiting slide plate 13 adopts an L-shaped structure.

[0044] A notch 19 is provided at the center of the limiting slide groove 18 , and the length and width of the notch 19 are the same as those of the limiting slide plate 13 , so that the limiting slide plate 13 can be separated from the limiting slide groove 18 at the notch 19 .

[0045] By adopting the above technical solution:

[0046] When the splint 8 moves horizontally, the limiting slide 13 moves horizontally inside the limiting slide groove 18, which can ensure the stability of the splint 8 when moving. A notch 19 is opened at the center position of the limiting slide groove 18, and the length and width of the notch 19 are the same as the length and width of the limiting slide plate 13, so that the limiting slide plate 13 can be separated from the limiting slide groove 18 at the notch 19. Such a structural setting makes it possible for the splint 8 or other structures on the splint 8 to be damaged when the splint 8 or other structures on the splint 8 are damaged. The pin shaft at the connection between the scissors frame rod 9 and the driving slider 15 can be removed first, and then the scissors frame rod 9 and the driving slider 15, and finally the splint 8 can be slid so that the limiting slide plate 13 reaches the notch 19 and then separates from the limiting slide groove 18 at the notch 19, that is, the disassembly of the splint 8 is completed, which is convenient for the repair and replacement of the splint 8 or other structures on the splint 8.

[0047] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
