[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Reference Figure 1-Figure 3 The utility model provides an embodiment: a caster with anti-collision and obstacle crossing function, including a mounting plate 1, the mounting plate 1 is fixedly connected to a side plate 2, the side plate 2 is hinged with a rotating shaft 3, the rotating shaft 3 is rotatably connected to a rotating frame 4, the rotating shaft 3 is rotatably connected to a gear 1 5, the rotating frame 4 is rotatably connected to a gear 2 6, the gear 2 6 is fixedly connected to a wheel body 7, the rotating shaft 3 is hinged to an articulated seat 1 8, the side plate 2 is hinged to an articulated seat 2 9, a spring 10 is provided between the articulated seat 1 8 and the articulated seat 2 9, and a damper 11 is provided between the articulated seat 1 8 and the articulated seat 2 9. By arranging three groups of wheel bodies 7, when the caster encounters a smaller obstacle, the wheel body 7 rotates, thereby forming a leg-like movement, and then crossing the obstacle, thereby improving the adaptability of the caster. Secondly, the spring 10 cooperates with the damper 11, so that when passing through small obstacles or potholes, the vibration of the equipment above the caster is reduced, and it is more stable, thereby improving the stability of the caster.
[0028] There are three gears 26 in total, gear 26 is meshed with gear 15, the mounting plate 1 is provided with a slide groove 12, the slide groove 12 is slidably connected with a slide rod 13, the slide rod 13 is fixedly connected with a baffle 14, the baffle 14 is hinged with a connecting rod 15, the mounting plate 1 is fixedly connected with a guide rail 16, the connecting rod 15 is hinged with a slider 17, the slider 17 is slidably connected with the guide rail 16, there are two sliders 17 in total, the slider 17 is fixedly connected with a spring 2 18, the two ends of the spring 2 18 are respectively fixedly connected to the two sliders 17, the slider 17 is fixedly connected with a fixed block 19, the fixed block 19 is fixedly connected with a damper 2 20, when colliding with a large obstacle, the baffle 14 contacts the obstacle first, the baffle 14 moves after the collision, pushing the connecting rod 15 to pull the spring 2 18, and the deformation of the spring 2 18 and the damper 20 absorbs the impact force transmitted to the caster during the collision, thereby avoiding damage caused by collision between the wheel body 7 and the object, thereby improving the safety of the caster.
[0029] Working principle: First, during normal driving, the mounting plate 1 is pushed, the mounting plate 1 drives the side plate 2 to move, the side plate 2 drives the rotating shaft 3 to move, the rotating shaft 3 drives the rotating frame 4 to move, the rotating frame 4 drives the gear 2 6 to move, the gear 2 6 drives the wheel body 7 to move, and under the influence of the device's own weight, the two wheel bodies 7 will contact the ground, and the wheel body 7 rotates due to the friction force, thereby continuously driving the device forward. When the caster encounters a small obstacle, the first wheel body 7 in the forward direction will be the first to contact it, and the wheel body 7 will no longer move forward due to the resistance. At the same time, the mounting plate 1 is still pushed, driving the rotating shaft 3 to move forward, and the position of the rotating shaft 3 is higher than the axis of the wheel body 7. Therefore, the rotating shaft 3 drives the gear 1 5 to rotate around the axis of the wheel body 7, and the upper wheel body 7 falls forward during the rotation process, passes the obstacle, and becomes the new first one in the forward direction. The wheel body 7 drives the gear 2 6 to rotate, the gear 2 6 drives the gear 1 5 to rotate, and the gear 1 5 drives the wheel body 7 that has just been stuck to rotate, so that it can climb over the obstacle. At this point, the caster has completed the obstacle crossing. When the caster encounters a large obstacle that cannot be crossed, because the obstacle is higher, the baffle 14 will first contact and collide with it. When the baffle 14 collides, it drives the slide bar 13 to slide along the slide groove 12. At the same time, the baffle 14 drives the connecting rod 15, and the connecting rod 15 drives the slider 17 to slide along the guide rail 16. The slider 17 stretches the spring 2 18. The slider 17 also drives the fixed block 19 to move, and the fixed block 19 pulls the damper 20. Under the displacement of the baffle 14 and the deformation of the spring 2 18 and the damper 20, the impact force transmitted to the caster during the collision is absorbed, thereby avoiding damage caused by collision between the wheel body 7 and the object, thereby improving the safety of the caster.
