Description

Technical Field

[0001] The utility model belongs to the technical field of automatic guided vehicles, in particular to a combined wheel of an AGV. Background Art

[0002] AGV is the abbreviation of automatic guided vehicle, which refers to an unmanned automated vehicle with automatic guidance equipment such as magnetic strips, tracks or lasers, which travels along a planned path, is powered by batteries, and is equipped with safety protection and various auxiliary mechanisms. Usually, multiple AGVs, control computers, navigation equipment, charging equipment and peripheral accessories form an AGV system. Its main working principle is that under the monitoring and task scheduling of the control computer, the AGV can accurately follow the prescribed path, and after reaching the designated location of the task, it completes a series of tasks. The control computer can decide whether to automatically charge in the charging area based on the AGV's own power. When the automatic guided vehicle is in use, its wheels will be affected by the terrain, causing it to bump. Because the automatic guided vehicle will be loaded with a certain amount of cargo, encountering bumpy roads may cause damage to structures such as wheels, thereby delaying the progress of cargo transportation. Therefore, an automatic guided vehicle with a shock-absorbing structure is very necessary.

[0003] In the Chinese patent with publication number CN219277604U, a highly adaptable AGV wheel train structure is mentioned, which relates to the technical field of AGV wheel train structure. Since the traditional AGV wheel train steering structure is too complicated and there is no professional shock-absorbing device to assist in shock absorption, when the wheel encounters bumps during operation, the structure is easy to loosen and cause damage. The traditional AGV wheel train structure has poor stability and is prone to tilting and dislocation during installation. The utility model includes a mounting plate, a wheel is movably mounted on the bottom of the mounting plate, and a shock-absorbing device is detachably mounted on one side of the wheel. The shock-absorbing device includes a connecting rod, a fixing rod is fixedly mounted on one end of the two connecting rods, and a telescopic column is symmetrically sleeved on the surface of the fixing rod. A slider is fixedly mounted on the top of the telescopic column, and the slider is slidably mounted in the mounting plate. The output end of the motor drives the first gear to rotate. When the first gear rotates, it drives the second gear and the rotating shaft to rotate. When the rotating shaft rotates, it drives the wheel in the bogie to steer.

[0004] However, although the above technical solution can achieve the purpose of assisting the installation of the entire device when in use, and the wheels play a certain shock-absorbing role, its support frame structure will move with the entire device when it moves subsequently. This will cause the support frame to have a relatively fixed position when encountering bumpy roads, so that some relatively protruding objects will block the support frame, making it difficult to pass, and the wheels will continue to move forward, causing the entire device to deviate to a certain extent when moving, which has certain limitations when in use. Utility Model Content

[0005] The purpose of the present invention is to provide a combination wheel for an AGV to solve the problem in the background art that the support frame is easily blocked by partially raised objects during movement, causing the entire device to deviate during movement.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The wheel assembly of claim 1, wherein the wheel assembly comprises a first arm, a second arm, and a second arm is mounted on the wheel assembly, wherein the arm is located adjacent to the wheel assembly and the second arm is located adjacent to the wheel assembly.

[0008] Preferably, a driving motor is fixedly connected to one side of the bottom of the mounting plate, the output end of the driving motor is fixedly connected to a first gear, the surface of the first gear is meshed with a second gear, the interior of the second gear is fixedly connected to a transmission shaft, the bottom end of the transmission shaft is fixedly connected to a turntable, and positioning plates are fixedly connected on both sides of the bottom of the turntable, and a vertical groove is provided inside the positioning plate.

[0009] Preferably, a second damping block is slidably connected to the interior of the vertical groove, a reinforcing rod is fixedly connected to the interior of the second damping block, and the wheel is rotatably arranged on the surface of the reinforcing rod.

[0010] Preferably, the top of the second damping block is fixedly connected to a second shock-absorbing spring, and the top of the second damping block is fixedly connected to a second guide rod.

[0011] Preferably, a receiving groove is provided at the bottom of the base plate, and the top end of the second guide rod passes through the interior of the receiving groove.

[0012] Preferably, four mounting holes are opened inside the mounting plate, the internal thread of the fixing plate is connected with a fastening bolt, and the surface thread of the fastening bolt passes through the interior of the base plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The fixed cylinder plays a certain supporting role when the whole device is installed. At the same time, it can achieve the effect of assisting movement through the universal ball. At the same time, it expands the contact area with the ground, disperses the force it receives, reduces its load force, and improves the effect of the wheel when moving. The universal ball also avoids the impact of bumps when moving, achieves the effect of shock absorption and buffering, and ensures the stable rolling of the universal ball.

[0015] (2) The wheels of the AGV can absorb shock when it moves, making it more adaptable to the ground and avoiding the loosening or even damage of parts caused by bumpy roads. To a certain extent, it can reduce the cost of replacing parts. At the same time, the shock-absorbing structure can turn with the wheels, which is more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 2:

[0025] See also Figures 1 to 3 As shown, a drive motor 13 is fixedly connected to one side of the bottom of the mounting plate 1, and a first gear 14 is fixedly connected to the output end of the drive motor 13. A second gear 15 is meshed with the surface of the first gear 14, and a transmission shaft 16 is fixedly connected to the interior of the second gear 15. The bottom end of the transmission shaft 16 is fixedly connected to a turntable 17. Positioning plates 18 are fixedly connected to both sides of the bottom of the turntable 17.

It should be noted that there is only one reinforcing rod 21, which passes through the interior of the second damping block 20 within the two positioning plates 18.

[0027] A second damping spring 22 is fixedly connected to the top of the second damping block 20. A second guide rod 23 is also fixedly connected to the top of the second damping block 20.

[0028] The bottom of the base plate 2 is provided with a receiving groove 24, and the top end of the second guide rod 23 passes through the inside of the receiving groove 24. By providing the receiving groove 24, a certain space is provided for the second guide rod 23 to move upward.

[0029] Four mounting holes 25 are formed within the mounting plate 1. Fastening bolts are threadedly connected to the interior of the fixing plate 4, and the surface threads of the fastening bolts extend through the interior of the base plate 2. The formation of the mounting holes 25 allows the mounting plate 1 to be installed in the appropriate position, and the fastening bolts secure the fixing plate 4 to the base plate 2.

[0030] The working principle of the present invention is as follows: the staff installs the entire device in the appropriate position through the mounting plate 1 and the mounting hole 25 in advance, and then installs the fixing plate 4 on the base plate 2 through the fastening bolts. Then the universal ball 9 contacts the ground. When the entire device is subsequently used, the staff controls the drive motor 13 to start, and the output end of the drive motor 13 drives the first gear 14 to rotate. The rotation of the first gear 14 drives the second gear 15 meshing with its surface to rotate, thereby rotating the transmission shaft 16. The rotation of the transmission shaft 16 drives the turntable 17 at its bottom to rotate, and then the turntable 17 drives the positioning plates 18 on both sides of its bottom to rotate. At the same time, the wheel 3 will also rotate to adjust its position. When encountering a bumpy road section, the wheel 3 will move upward, and the reinforcing rod 21 will drive the second resistance The damping block 20 moves upward, causing the second damping block 20 to squeeze the second shock-absorbing spring 22 upward, so that the bumping force on the wheel 3 is buffered, and at the same time the second guide rod 23 moves upward and eventually extends to the inside of the accommodating groove 24, so that the entire device plays a shock-absorbing role. At the same time, the universal ball 9 will also move with the device. When the universal ball 9 is bumped, the universal ball 9 will push the accommodating cavity 8 upward, and then the accommodating cavity 8 will squeeze the extrusion plate 7 upward for a certain distance through the short rod. Then the first damping block squeezes the first shock-absorbing spring 10 upward, so that the force on the universal ball 9 is absorbed, which plays a buffering role. In this process, the first guide rod 12 moves upward, so that it passes through the inside of the fixed rod 5, ensuring that the entire device plays a shock-absorbing effect while moving.
