Embodiment 1
[0045] see figure 1 , the present embodiment provides a driving wheel suspension damping mechanism 200, which is suitable for installation on the chassis of the AGV trolley (not shown in the figure).
[0046] Wherein, the driving wheel suspension damping mechanism 200 mainly includes a fixing plate 201 , a wheel bracket 210 and a first damping unit 220 .
[0047] The fixing plate 201 is made of metal or hard polymer material, such as aluminum profile in this embodiment, which is light in weight and can effectively reduce the load of the AGV trolley.
[0048] Wherein, the projection of the fixing plate 201 on the horizontal plane may be strip-shaped, and in this embodiment, the projection of the fixing plate 201 on the horizontal plane is a rectangle. Wherein, the direction in which the driving wheel 131 keeps moving linearly is taken as the advancing direction, and the advancing direction is parallel to the longitudinal direction of the projection of the fixing plate 201 on t...
Embodiment 2
[0072] see image 3 , Figure 4 as well as Figure 5 The present embodiment provides an AGV trolley 10, which mainly includes a chassis 100, a housing 120, a running mechanism, the driving wheel suspension and damping mechanism 200 provided in Embodiment 1, a load-bearing jacking structure, an obstacle detection and avoidance system, and a controller 180.
[0073] Among them, such as Figure 6 As shown, when the projected shape of the chassis 100 on the horizontal plane is a rounded rectangle, the rear and the front of the vehicle are arranged in the length direction of the rounded rectangle.
[0074] see Figure 6 The side of the chassis 100 facing away from the ground is provided with a first milling groove 101 , a second milling groove 103 and a third milling groove 106 , and the chassis 100 is provided with a notch 107 for the driving wheel 131 to extend out of the chassis 100 in cooperation with the driving wheel 131 .
[0075] see Figure 7 , wherein, the chassis 100...

Abstract
The invention provides a hanging shock-absorption mechanism for driving wheels and an AGV, and relates to the field of robots. The hanging shock-absorption mechanism for the driving wheels comprises afixing plate, wheel supports used for installing the driving wheels and first shock-absorption units, wherein each first shock-absorption unit comprises a first guide shaft, a first linear bearing cooperating with the first guide shaft and an elastic piece sleeving the circumference of the first guide shaft; the two ends of each elastic piece are connected with the corresponding wheel support andthe fixing plate respectively; the first linear bearings are fixedly arranged on the fixing plate, each first guide shaft is provided with a first end and a second end which are opposite, the first ends are fixedly connected with the wheel supports, the second ends slidably penetrate through the fixing plate and the first linear bearings, and each second end is provided with a limiting part usedfor limiting the first guide shaft to being separated from the corresponding linear bearing, so that the wheel supports are hung on the fixing plate. It is ensured that during long-term load operation, there are no rigid friction or wear between the hanging shock-absorption mechanism for the driving wheels and the rack, the precision of the running path of the AGV is high, and the service life islong.
Description
technical field [0001] The present application relates to the field of robots, in particular, to a driving wheel suspension shock absorbing mechanism and an AGV trolley. Background technique [0002] In the development of modern industry, it advocates high efficiency, speed, reliability, and liberates people from simple work. Robots have gradually replaced people in various jobs. Robots have the characteristics of programmable, coordinated operations, and sensor-based control. Automated Guided Vehicle (Automated Guided Vehicle, referred to as AGV) is a kind of mobile robot. It is a modern industrial logistics system. The important equipment is mainly used for storage and transportation of various materials, and provides a guarantee for the flexibility, integration and efficient operation of the system. [0003] Although the existing AGV trolley is equipped with a shock-absorbing structure, in the actual use process, when running on an uneven road under light load, there wil...
