Description

Technical Field

[0001] The utility model relates to the technical field of intelligent logistics trolleys, in particular to a suspension device for an intelligent logistics trolley. Background Art

[0002] Smart logistics carts are mobile devices that use automation and intelligent technology to transport and handle goods. These carts are typically equipped with sensors, cameras, lidar, and other equipment, enabling autonomous navigation and obstacle avoidance in indoor or outdoor environments. They are widely used in warehousing, distribution, factories, hospitals, airports, and other locations. Suspension devices are essential components for ensuring the cart's stable operation under varying surface conditions.

[0003] Since the bottom of the existing logistics cart generally uses a shock absorber component to give it a certain buffering adaptability effect, and although the cost of achieving the cushioning effect only through the shock absorber component is low, the cushioning effect is not obvious in actual use, and the overall practical effect still needs to be improved. Utility Model Content

[0004] The purpose of the present utility model is to solve the above-mentioned problem and propose an intelligent logistics trolley suspension device, which improves the existing intelligent logistics trolley. The bottom of the logistics trolley generally uses a shock absorber component to give it a certain buffering adaptability effect. Although the cost of achieving the cushioning effect only by the shock absorber component is low, the cushioning effect is not obvious in actual use, and the overall practical effect still needs to be strengthened.

[0005] A suspension device for an intelligent logistics trolley includes a running wheel body, a mounting member, and a rigid support member. The running wheel body is provided with two groups, and the side outer walls of the two groups of running wheel bodies located at the wheel hub position are both provided with mounting members. A rigid support member is connected between the two groups of mounting members. A first buffer protection mechanism is provided above the rigid support member, a second buffer protection mechanism is provided on the side of the first buffer protection mechanism, and a portable assembly mechanism is provided on the side of the second buffer protection mechanism.

[0006] The first buffer protection mechanism includes a leaf spring, a positioning pressure plate and a positioning bolt. The leaf spring is symmetrically arranged on the top outer wall of the rigid support member. The positioning pressure plate is fitted on the top outer wall of the leaf spring in the middle position. Two groups of mounting grooves are symmetrically opened on the top outer wall of the positioning pressure plate, and the internal threads of the mounting grooves are installed with positioning bolts, and the bottom end of the positioning bolts is threadedly installed with the rigid support member.

[0007] Preferably, the second buffer protection mechanism includes a limit support plate and a rotating support member, and two groups of limit support plates are symmetrically arranged on the top outer wall of the rigid support member. There are two limit support plates in the same group, and a rotating support member is rotatably installed between the two limit support plates in the same group.

[0008] Preferably, a support bar is provided on the top outer wall of the rotating support member, and the top outer wall of the support bar is connected to the bottom outer wall of the air shock absorber.

[0009] Preferably, the portable assembly mechanism includes a support platform and a support portion, the top outer wall of the air shock absorber is provided with the support platform, and the top outer wall of the support platform is provided with the support portion.

[0010] Preferably, connecting pieces are rotatably mounted on the outer walls of both sides of the support portion, and a positioning mounting plate is connected between the top outer walls of the two groups of connecting pieces.

[0011] Preferably, two groups of thread grooves are symmetrically formed on the outer wall of the top end of the positioning and mounting plate, and fastening bolts are installed on the internal threads of the thread grooves.

[0012] The beneficial effects of the utility model are:

[0013] 1. When the intelligent logistics trolley suspension device is in use, an air shock absorber and a leaf spring are installed at the bottom of the intelligent logistics trolley for suspension buffering. The air shock absorber can effectively absorb the impact and vibration from the ground, so that the trolley remains stable during driving and reduces the risk of damage to the goods. The leaf spring has a high load-bearing capacity and can withstand heavier goods. At the same time, it provides the necessary support to ensure that the logistics trolley remains stable during transportation. The two work together to achieve a better overall suspension buffering effect and can make up for the problem of insufficient buffering force of a single component. The overall structural design is ingenious and has good practical effect.

[0014] 2. When the intelligent logistics trolley suspension device is in use, a rotatable mounting part is provided on the top of the air shock absorber, so that the assembly process of the air shock absorber and the walking trolley can be completed more quickly and conveniently by adjusting the position of the mounting component during installation. Compared with the general fixed hardware installation, the above design is more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] When implementing: Figure 1-5 As shown, a suspension device for an intelligent logistics trolley includes a walking wheel body 1, a mounting member 2, and a rigid support member 3: two groups of walking wheel bodies 1 are provided, and the side outer walls of the two groups of walking wheel bodies 1 located at the wheel hub position are both provided with mounting members 2, and a rigid support member 3 is connected between the two groups of mounting members 2. A first buffer protection mechanism 4 is provided above the rigid support member 3, a second buffer protection mechanism 5 is provided on the side of the first buffer protection mechanism 4, and a portable assembly mechanism 6 is provided on the side of the second buffer protection mechanism 5;

[0023] The first buffer protection mechanism 4 includes a leaf spring 41, a positioning pressure plate 42 and a positioning bolt 43. The leaf spring 41 is symmetrically arranged on the top outer wall of the rigid support member 3. The positioning pressure plate 42 is fitted on the top outer wall of the leaf spring 41 at the middle position. The top outer wall of the positioning pressure plate 42 is symmetrically penetrated with two groups of mounting grooves, and the internal threads of the mounting grooves are installed with positioning bolts 43, and the bottom ends of the positioning bolts 43 are threadedly installed with the rigid support member 3; the arrangement of the positioning pressure plate 42 and the positioning bolt 43 here both has the effect of positioning and installing the leaf spring 41, so that it can stably position the leaf spring 41 above the rigid support member 3, and when an external load (such as the weight of the vehicle or the impact of the ground) is applied to the leaf spring 41, the steel plate will undergo elastic deformation, so that this deformation process can absorb part of the external impact energy, thereby achieving a shock-absorbing and protective effect for the logistics trolley, so that it can travel stably on the ground;

[0024] The second buffer protection mechanism 5 includes a limiting support plate 51 and a rotating support member 52. Two groups of limiting support plates 51 are symmetrically arranged on the top outer wall of the rigid support member 3. There are two limiting support plates 51 in the same group, and a rotating support member 52 is rotatably installed between the two limiting support plates 51 in the same group. A support bar 53 is provided on the top outer wall of the rotating support member 52, and the top outer wall of the support bar 53 is connected to the bottom outer wall of the air shock absorber 54; the setting of the limiting support plate 51, the rotating support member 52 and the support bar 53 here have an auxiliary installation effect on the air shock absorber 54, and then the setting of the air shock absorber 54 can effectively absorb and disperse energy when the wheel is impacted or vibrated. When external force is applied to the shock absorber, the internal air will be compressed to form a certain pressure, thereby achieving a better shock-absorbing effect.

[0025] The portable assembly mechanism 6 includes a support platform 61 and a support part 62. The top outer wall of the air shock absorber 54 is provided with a support platform 61, and the top outer wall of the support platform 61 is provided with a support part 62. The outer walls on both sides of the support part 62 are rotatably installed with connecting parts 63. A positioning mounting plate 64 is connected between the top outer walls of the two groups of connecting parts 63. The top outer wall of the positioning mounting plate 64 is symmetrically penetrated with two groups of thread grooves 65, and the internal threads of the thread grooves 65 are installed with fastening bolts 66; the setting of the positioning mounting plate 64, the thread grooves 65 and the fastening bolts 66 here enables the air shock absorber 54 to be stably installed at the bottom end of the logistics cart, and the setting of the support part 62 and the connecting part 63 enables the above-mentioned positioning mounting plate 64 to have a certain tilt adjustment effect, so that it can better adapt to the installation needs of the air shock absorber 54, and there is no need for subsequent tedious adjustment procedures to calibrate the installation position.

[0026] When the present invention is in use, the positioning plate 42 and the positioning bolt 43 are both arranged to position and install the leaf spring 41, so that the leaf spring 41 is stably positioned above the rigid support 3. When an external load (such as the weight of the vehicle or the impact of the ground) is applied to the leaf spring 41, the steel plate will undergo elastic deformation, thereby absorbing a portion of the external impact energy during this deformation process, thereby achieving a shock-absorbing and protective effect on the logistics trolley, allowing it to travel stably on the ground.

[0027] The arrangement of the position-limiting support plate 51, the rotating support member 52, and the support bar 53 here assists the installation of the air shock absorber 54. Furthermore, the arrangement of the air shock absorber 54 can effectively absorb and disperse energy when the wheel is subjected to impact or vibration. When external force is applied to the shock absorber, the air inside will be compressed, forming a certain pressure, thereby achieving a better shock-absorbing effect.

[0028] The arrangement of the positioning mounting plate 64, the threaded groove 65 and the fastening bolts 66 here enables the air shock absorber 54 to be stably installed at the bottom end of the logistics cart, while the arrangement of the support portion 62 and the connecting member 63 enables the above-mentioned positioning mounting plate 64 to have a certain tilt adjustment effect, so as to better adapt to the installation needs of the air shock absorber 54, without the need for subsequent tedious adjustment procedures to calibrate the installation position.

[0029] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
