[0002] AGVs are unmanned transportation devices with functions such as automatic navigation, handling, positioning, and obstacle avoidance. AGVs typically use laser, vision, or electromagnetic navigation methods, enabling them to navigate autonomously in complex environments and complete various transportation tasks. AGVs are widely used in logistics, manufacturing, and medical fields, improving work efficiency, reducing labor costs, and enhancing transportation safety.

[0003] Application number CN202222195283.2 discloses an auxiliary braking device for AGVs, including a vehicle body and other structures. Through an auxiliary fixing device, it reduces the reverse force after the AGV stops moving, making the AGV more stable when stopped. However, in practical use, once the rubber brake pads contact the ground, the contact becomes continuous friction, leading to severe wear of the rubber brake pads and significantly reducing their service life.

[0013] In a preferred embodiment, the present invention can be further configured such that: both ends of the AGV are fixedly connected to anti-collision barriers, which are made of steel.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, the movable end of the hydraulic cylinder extends, and under mechanical transmission, the pressure plate causes the damping pad at its bottom to adhere to the ground. The friction between the damping pad and the ground acts as a brake, and the resulting reaction force is then applied to the hydraulic cylinder.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of an AGV auxiliary braking device provided by the present invention.

[0031] Example 1:

[0032] Combination Figure 1-5 As shown, the present invention provides an AGV auxiliary braking device, which includes a transport mechanism 100, a deceleration mechanism 200 and a drag-increasing mechanism 300, wherein the transport mechanism 100 includes an AGV trolley 110.

[0033] The deceleration mechanism 200 includes a large rod frame 210 connected to the bottom of the AGV trolley 110, a pressure plate 220 rotatably sleeved on the outside of the large rod frame 210, two torsion springs 230 connected between the large rod frame 210 and the pressure plate 220, and a damping pad 240 embedded in the bottom of the pressure plate 220.

[0034] The resistance-increasing mechanism 300 includes a small rod frame 310 fixedly connected to the bottom of the AGV trolley 110, a rotating connector 320 rotatably sleeved on the outside of the small rod frame 310, two T-shaped rods 330 installed on one side of the rotating connector 320, a hydraulic cylinder 340 slidably connected between the two T-shaped rods 330, and two springs 350 connected between the rotating connector 320 and the hydraulic cylinder 340. The movable end of the hydraulic cylinder 340 is movably connected to the top of the pressure plate 220.

[0035] Furthermore, the small rod frame 310 is positioned away from the large rod frame 210. Both the large rod frame 210 and the small rod frame 310 are configured as I-beams and made of alloy materials. Using alloy materials to make the large rod frame 210 and the small rod frame 310 can ensure their strength and hardness, and ensure that they can stably support the components in the deceleration mechanism 200 and the drag-increasing mechanism 300.

[0036] Furthermore, the two torsion springs 230 are vertically symmetrical about the pressure plate 220. The diameter of the torsion springs 230 is smaller than the diameter of the pressure plate 220. The layout design of the torsion springs 230 can stabilize the pressure plate 220, so that the damping pad 240 under the pressure plate 220 can firmly adhere to the ground.

[0037] Furthermore, the bottom of the damping pad 240 is provided with multiple shallow grooves, which are equally spaced and arranged in a row. The shallow grooves can enhance the friction between the damping pad 240 and the ground.

[0038] Furthermore, the two springs 350 are vertically symmetrical about the hydraulic cylinder 340, and the two springs 350 are respectively sleeved on the outside of the two T-shaped rods 330. The layout design of the springs 350 can reduce the probability of the springs 350 going out of shape and ensure the service life of the springs 350.

[0039] Example 2:

[0040] Combination Figure 1 and Figure 5 As shown, based on Embodiment 1, the AGV trolley 110 is provided with a weight reduction mechanism 400 on its top. The weight reduction mechanism 400 includes a tray 410 fixedly connected to the top of the AGV trolley 110 and a plurality of auxiliary wheels 420 connected to the tray 410. The plurality of auxiliary wheels 420 are arranged in a matrix, and the bottom of the auxiliary wheels 420 is located on the same horizontal plane as the bottom of the AGV trolley 110. By setting up the weight reduction mechanism 400, the load on the AGV trolley 110 when transporting goods can be alleviated, and the load on the AGV trolley 110 during operation can be reduced.

[0041] Example 3:

[0042] Combination Figure 1 and Figure 5As shown, in the above embodiment, both ends of the AGV trolley 110 are fixed with anti-collision rails 500. The anti-collision rails 500 are made of steel. Setting up anti-collision rails 500 can improve the collision resistance of the AGV trolley 110.

[0043] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the AGV trolley 110 cooperates with the pallet 410 to transport goods. During transport, if braking is required, the movable end of the hydraulic cylinder 340 will extend. Then, under mechanical transmission, the pressure plate 220 will cause the damping pad 240 at its bottom to adhere to the ground. The friction between the damping pad 240 and the ground will act as a brake. At the same time, the reaction force generated will be applied to the hydraulic cylinder 340. The hydraulic cylinder 340 will repeatedly compress the two springs 350 at its top, and then rotate the connecting piece 320 to swing, thereby buffering and offsetting the reaction force. Then, the damping pad 240 will intermittently adhere to the ground, thereby reducing the wear of the damping pad 240 during use and extending the service life of the damping pad 240.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
