Description

Technical Field

[0001] The utility model relates to the technical field of AGVs, and in particular to an AGV chassis structure and an AGV trolley for preventing wheels from slipping. Background Art

[0002] The AGV is an efficient, intelligent and safe unmanned transport equipment, which is widely used in warehousing, production lines, airports and other scenarios. It provides strong support for the development of modern logistics industry. It does not require a driver in industrial applications and uses rechargeable batteries as its power source.

[0003] Many factory floors have many potholes and uneven surfaces due to long-term use. Most existing AGV bodies have four wheels fixed separately on the chassis. When driving on uneven surfaces, due to the principle that three points determine a plane, one wheel will have poor contact with the ground or even hang in the air. When the AGV is fully loaded and driving on such a surface, the wheels will slip, resulting in insufficient driving force for the vehicle and inability to leave the pothole area, affecting the transportation efficiency of the AGV. In severe cases, the vehicle will report an error and stop. Utility Model Content

[0004] The utility model aims to provide an AGV chassis structure and an AGV trolley that prevent wheels from slipping, so as to solve the problem that the existing AGV slips in potholes, resulting in insufficient driving force of the vehicle and inability to leave the potholes, affecting the transportation efficiency of the AGV, and in severe cases causing the vehicle to report an error and stop.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an AGV chassis structure for preventing wheels from slipping, comprising:

[0006] a chassis body; and

[0007] The swing bridge mechanism is arranged on one side of the chassis body, and the swing bridge mechanism includes a swing bridge fixing part. The swing bridge mechanism also includes a swing bridge support rotatably connected to the swing bridge fixing part and fixed to the chassis body. The swing bridge support and the swing bridge fixing part can rotate relative to each other to balance when the force is unbalanced.

[0008] Preferably, the swing bridge fixing member includes a drive mounting plate, which is arranged on one side of the chassis body, with two rib plates fixed on the top of the drive mounting plate, and two rotating shaft support plates fixedly connected to the middle part of the bottom end of the drive mounting plate, the rotating shaft support plate passes through a swing bridge rotating shaft, and the swing bridge rotating shaft is fixed to the rotating shaft support plate.

[0009] Preferably, the arrangement direction of the swing bridge shaft is perpendicular to the drive mounting plate.

[0010] Preferably, a pendulum bridge support is rotatably provided at both ends of the pendulum bridge shaft, and a grease port is provided on the side of the pendulum bridge support.

[0011] Preferably, two rotatable wheels are provided at both ends of the bottom of the driving mounting plate.

[0012] Preferably, two rotatable wheels are provided on the other side of the chassis body away from the drive mounting plate.

[0013] An AGV trolley is characterized by comprising the AGV chassis structure for preventing wheels from slipping.

[0014] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0015] The AGV chassis structure and AGV trolley for preventing wheels from slipping are provided with a swing bridge mechanism on one side of a chassis body, wherein the swing bridge mechanism comprises a swing bridge fixing part and a swing bridge support, wherein the swing bridge support and the swing bridge fixing part rotate relative to each other and are fixed to the chassis body, and the swing bridge support and the swing bridge fixing part rotate relative to each other to balance when the forces are unbalanced. When the road surface on one side is uneven and one wheel is suspended in the air, the swing bridge fixing part and the chassis body can rotate to balance so that the wheel touches the ground to prevent slipping, thereby solving the problem that most existing AGV bodies have four wheels fixed separately on the chassis, which may cause one wheel to have poor contact with the ground or even be suspended in the air when driving on uneven ground, and the wheel may slip easily, resulting in insufficient driving force of the vehicle and inability to drive out of potholes, affecting the transportation efficiency of the AGV, and in severe cases causing the vehicle to report an error and stop.

[0021] 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.

[0022] like Figure 1-Figure 4 As shown, an AGV chassis structure for preventing wheels from slipping includes a chassis body 1 and a swing bridge mechanism 2, the swing bridge mechanism 2 is arranged on one side of the chassis body 2, the swing bridge mechanism 2 includes a swing bridge support 21 and a swing bridge fixing 22, the swing bridge support 21 is rotatably connected to the swing bridge fixing 22, the swing bridge support 21 is fixedly connected to the chassis body 2, the swing bridge support 21 and the swing bridge fixing 22 can rotate relative to each other when the force is unbalanced and stop when they are balanced. When the road surface on one side is uneven and one wheel 3 is suspended in the air, since the swing bridge support 21 can rotate and the swing bridge fixing 22 is fixed to the swing bridge support 21, the swing bridge fixing 22 can rotate with the rotation of the swing bridge support 21, and the swing bridge fixing 22 and the chassis body 1 can rotate to balance so that the wheel touches the ground to prevent slipping.

[0023] like Figure 1-Figure 4 As shown, the swing bridge fixing member 22 includes a driving mounting plate 221, a rib plate 222, a rotating shaft support plate 223 and a swing bridge rotating shaft 224. The driving mounting plate 221 is arranged on one side of the chassis body 1. Two rib plates 222 are fixed on the top of the driving mounting plate 221. The driving mounting plate 221 is welded to the rib plate 222. Two rotating shaft support plates 223 are fixedly connected to the middle part of the bottom end of the driving mounting plate 221. The driving mounting plate 221 is welded to the rotating shaft support plate 223. The rotating shaft support plate 223 penetrates a swing bridge rotating shaft 224. The swing bridge rotating shaft 224 is fixedly connected to the rotating shaft support plate 223. Therefore, the swing bridge fixing member 22 is an integral whole. The arrangement direction of the swing bridge rotating shaft 224 is perpendicular to the driving mounting plate 221. A swing bridge support 21 is rotatably arranged at both ends of the swing bridge rotating shaft 224. A grease port 23 is provided on the side of the seat 21, and grease can be added to the connection between the swing bridge shaft 224 and the swing bridge support 21 through the grease port 23 to maintain a good lubrication effect, so that the rotation of the swing bridge support 21 is smoother. Two rotatable wheels 3 are fixed to the two ends of the bottom of the driving mounting plate 221, and two rotatable wheels 3 are fixed to the other side of the chassis body 1 away from the driving mounting plate 221 through a plate. The two wheels of the chassis body 1 away from the driving mounting plate 221 are both arranged on the plate. Therefore, the two wheels 3 on one side of the chassis structure on the swing bridge mechanism 2 are independent, and the other two wheels 3 are separately fixed on the chassis body 1, and are independent, rather than four wheels being separately independent. The wheels 3 at the bottom of the chassis are rear-wheel drive, and the driving form of the rear wheels 3 is controlled by a motor.

[0024] Also provided is an AGV trolley, comprising the AGV chassis structure for preventing wheels from slipping.

[0025] In actual use, when the AGV vehicle equipped with the chassis structure travels on an uneven road surface, when the two wheels 3 on the swing bridge mechanism 2 are on the uneven road surface, the wheels 3 on the swing bridge mechanism 2 are suspended and not firmly grounded, the two wheels on the other side are horizontally grounded, the vehicle body is in a horizontal state, and the swing bridge fixing part 22 rotates with the swing bridge support 21, so the swing bridge fixing part 22 rotates to make the two wheels 3 on the swing bridge mechanism 2 completely grounded, and the swing bridge fixing part 22 is in a tilted state at this time, and the AGV vehicle continues to move forward, preventing the occurrence of slipping.

[0026] When the two wheels 3 on the chassis body 1 away from the swing bridge mechanism 2 are located on an uneven ground, the two wheels 3 away from the swing bridge mechanism 2 are not firmly on the ground and are suspended in the air. At this time, the two wheels 3 on the swing bridge mechanism 2 are horizontally on the ground, and the swing bridge fixing member 22 is in a horizontal state. Since the chassis body 1 and the swing bridge support 21 are fixedly connected, the chassis body 1 rotates to make the two wheels 3 away from the swing bridge mechanism 2 touch the ground. At this time, the AGV body including the chassis body 1 is in a tilted state, and the vehicle continues to move forward, preventing the AGV trolley from slipping.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
