Description

Technical Field

[0001] The utility model belongs to the field of mobile devices, and in particular relates to a new AGV trolley. Background Art

[0002] AGV is a mobile device widely used in the industrial field. According to the way of movement, AGV can be divided into AGV that moves along the track and AGV that can move freely. AGV that can move freely has a wider range of usage scenarios because its moving direction is not fixed.

[0003] In the prior art, a freely movable AGV usually directly mounts wheels on a frame, and the wheels drive the entire AGV to move. However, the conventional AGV mentioned above has some shortcomings. The main shortcomings are that, since the AGV can move freely, obstacles often appear on the moving path of the AGV (for example, when the AGV passes through the air shower door, the entrance of the air shower door is higher), which makes it impossible for the AGV to pass normally.

[0004] In summary, the prior art has the problem that the AGV cannot pass through obstacles. Utility Model Content

[0005] The utility model provides a novel AGV trolley, and its purpose is to solve the problem that the conventional novel AGV trolley cannot pass through obstacles.

[0006] In order to achieve the above-mentioned object, the utility model provides a new AGV vehicle, comprising a vehicle body and a power module, wherein the power module is installed on the side of the vehicle body;

[0007] The power module includes a wheel unit and a connecting structure, the wheel unit is connected to the vehicle body via the connecting structure, the connecting structure includes a connecting piece and a telescope, both ends of the connecting piece are rotatably connected to the vehicle body and the wheel unit respectively, and both ends of the telescope are also rotatably connected to the vehicle body and the wheel unit. The telescope telescopes and moves to raise or lower the wheel unit.

[0008] In this solution, the telescopic device can drive the wheel unit to rise or fall through the telescopic movement of the telescopic device. When it is necessary to cross an obstacle, the telescopic device drives the wheel unit to rise so that the obstacle will not hinder the wheel unit; after the wheel unit crosses the obstacle, the telescopic device drives the wheel unit to fall. This solution uses a power module to achieve obstacle crossing for the AGV trolley, solving the shortcomings of conventional AGV trolleys in the prior art.

[0009] Preferably, in order to ensure that the wheel unit is more stable when it is driven to rise or fall, it is preferred that both sides of the wheel unit are provided with connectors to connect with the vehicle body.

[0010] In this solution, connecting pieces are arranged on both sides of the wheel unit, and the wheel unit is supported by the connecting pieces on both sides, so that the wheel unit is more stable. In this solution, connecting pieces are arranged on both sides, and the connecting pieces on both sides play a supporting role at the same time, so that the wheel is more stable compared with the connecting pieces on only one side.

[0011] Preferably, the retractor in this solution is located between the connecting members on both sides.

[0012] In this solution, the expansion joint is located between the connecting members on both sides. When the expansion joint is driven, the connecting members on both sides are subjected to force at the same time, and the wheel unit is more stable.

[0013] Preferably, in order to ensure that the wheel unit is more stably connected to the vehicle body, in this solution, at least two connecting members are preferably provided on each side of the wheel unit to connect to the vehicle body.

[0014] In this solution, since at least two connectors are provided on each side of the power module, the more connectors there are, the tighter the connection between the power module and the vehicle body can be, and the power module and the vehicle body can be prevented from being separated. Compared with a single connector, by providing at least two connectors, the power module will not be separated from the vehicle body even if one of the connectors is broken.

[0015] Preferably, in order to ensure that both sides of the vehicle body can be supported by the power module, in the embodiment of the present disclosure, the power module is preferably provided on both sides of the vehicle body respectively.

[0016] In this solution, the power modules on both sides support the left and right sides of the vehicle body respectively. The left and right sides of the vehicle body are supported, the vehicle body is more stable, and the vehicle body is prevented from tipping over.

[0017] Preferably, in order to ensure that both the front and rear ends of the vehicle body can be supported, the present solution preferably provides a plurality of power modules on the side of the vehicle body, and the plurality of power modules are arranged in a straight line.

[0018] In this solution, several power modules are used to support the front and rear ends of the vehicle body respectively, ensuring that the front and rear ends of the vehicle body remain stable and preventing the vehicle body from tipping over. Compared with a single power module, the vehicle body is in a stable state by supporting the vehicle body with several power modules.

[0019] Preferably, in order to make the structure simpler, the present solution preferably configures a first mounting portion on the top of the vehicle body, and the power modules located on both sides are mounted in cooperation with the first mounting portion.

[0020] This solution provides a first installation portion for installing the expanders on both sides, so compared with separately configuring the first installation portions, the structure of the entire device is simpler and the device is more integrated.

[0021] Preferably, since only one first mounting portion is provided, the vehicle body will interfere with the movement of the telescope. In this solution, preferably, an opening is provided on the side of the first mounting portion, and the opening is used to accommodate the telescope.

[0022] In this solution, an opening is arranged on the side of the first mounting portion, and the retractor is accommodated in the opening. When the retractor moves in a telescopic manner, the retractor is accommodated in the opening, and the retractor will not be interfered.

[0023] Preferably, in order to drive the vehicle body, the wheel unit preferably includes a wheel and a driver, wherein the driver is in transmission connection with the wheel, and the driver drives the wheel to rotate. In this solution, the driver drives the wheel to rotate, and the wheel serves as a driving force, thereby driving the vehicle body to move.

[0024] The beneficial effect of the utility model is that the telescopic device can drive the wheel unit to rise or fall through the telescopic movement of the telescopic device. When it is necessary to cross an obstacle, the telescopic device drives the wheel unit to rise, so that the obstacle will not hinder the wheel unit; after the wheel unit crosses the obstacle, the telescopic device drives the wheel unit to fall. The solution realizes the obstacle crossing of the AGV trolley through the power module, solving the shortcomings of the conventional AGV trolley in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

The plurality of power modules 2 can be 2, 3, 4 or 5, etc., which is not limited in the embodiment of the present disclosure.

[0035] Take an application scenario as an example: when the vehicle body 1 is moving, the power modules 2 located on the left and right sides of the vehicle body 1 can support the left and right sides of the vehicle body 1, and the power modules 2 located at the front and rear ends of the vehicle body 1 support the front and rear ends of the vehicle body 1. Each direction of the vehicle body 1 is supported by the power modules 2 at different positions, and the vehicle body 1 can move normally.

[0036] The power module 2 in the embodiment of the present disclosure includes a wheel unit 23 and a connection structure, such as Figure 2 and Figure 3As shown, the wheel unit 23 includes a driver 232, a wheel 231 and a wheel 231 frame. The driver 232 is preferably a driving motor, and the driving motor is mounted on the wheel 231 frame by welding or fastener connection. The wheel 231 is mounted on the output shaft of the driving motor. When the driver 232 is working, the driver 232 drives the wheel 231 to rotate, and the wheel 231 drives the vehicle body 1 to move. The surface of the wheel 231 can be provided with convex patterns to reduce the slippage of the wheel 231.

[0037] It should be noted that, in addition to the above-mentioned structure, other wheel 231 modules in the prior art, such as a steering wheel module, may be installed on the vehicle frame.

[0038] In the embodiment of the present disclosure, a first mounting portion 11 is provided at the middle position of the top of the vehicle body 1. Figure 2 As shown, the first mounting portion 11 corresponds to the power modules 2 located on both sides. A second mounting portion is provided at the bottom of the vehicle body 1, and the second mounting portion is provided at the left and right sides of the bottom of the vehicle body 1. The first mounting portion 11 and the second mounting portion are U-shaped, and the first mounting portion 11 and the second mounting portion can be installed on the vehicle body 1 by welding.

[0039] The connection structure includes a connecting member 21 and a telescopic device 22. The connecting member 21 is a long strip connecting plate, and the telescopic device 22 is a telescopic cylinder or a telescopic oil cylinder. In the embodiment disclosed herein, the two ends of the connecting member 21 are rotatably connected to the second mounting portion and the wheel 231 frame respectively arranged at the bottom of the vehicle body 1. During implementation, axial holes can be arranged at the ends of both ends of the connecting member 21, and a rotating shaft is arranged inside the axial hole to connect with the second mounting portion or the wheel 231 frame.
