Description

Technical Field

[0001] The utility model relates to an automatic guided vehicle, in particular to a camera turntable used in an automatic guided vehicle Background Art

[0002] Automated guided vehicles can navigate by using the cameras they carry to capture images of the surrounding environment. Whether the cameras can capture a comprehensive view of the surrounding environment from all angles is crucial for correct navigation and movement.

[0003] Chinese utility model patent publication number CN212617263U discloses a camera drive device for an AGV vehicle, comprising a turntable, a vertical support, and a camera support. A rotating mechanism is provided at the bottom of the turntable to drive the turntable's rotation. The vertical support is mounted on the turntable. A lead screw and a slide rail are vertically mounted on the vertical support. The camera support is connected to the lead screw via a lead screw nut. The top of the lead screw is mounted on the vertical support via a bearing. A lifting motor is provided at the other end of the lead screw. The camera support is connected to the slide rail via a slider. A mounting platform is horizontally mounted on the top of the camera support. The rotating mechanism includes a driven gear ring, a driving gear, and a rotating motor. The driven gear ring meshes with the driving gear. The driving gear is driven by the rotating motor. The driven gear ring is fixed to the bottom of the turntable. The bottom of the lead screw passes through the turntable and is connected to the lifting motor. The lead screw and the driven gear ring are concentric. The camera can be driven to lift and lower vertically and rotate about the Z axis, with the center of rotation close to the camera itself, reducing mapping errors.

[0004] Although the above device can realize the rotation of the camera on the automatic guided vehicle in the horizontal plane and the lifting in the vertical plane, it cannot make the camera rotate in the vertical plane to more comprehensively shoot the surrounding environment. Summary of the Invention

[0005] Purpose of the utility model: The purpose of the utility model is to provide a camera turntable for an automatic guided vehicle, which can rotate the camera on the automatic guided vehicle in the horizontal and vertical planes.

[0006] Technical solution: The camera turntable used for an automatic guided vehicle described in the utility model includes a turntable, a first motor and a camera bracket. The turntable is provided with a camera bracket and a second motor for driving the camera bracket to rotate. The rotation axes of the turntable and the camera bracket are perpendicular to each other.

[0007] Based on the above technical solution, a camera bracket and a second motor that independently drives its rotation are provided on the turntable. The rotation axis of the camera bracket and the turntable are perpendicular to each other, so that when the first motor drives the turntable to rotate in the horizontal direction, the second motor can drive the camera bracket to rotate in the vertical direction; in this way, the camera can be driven to rotate in the horizontal and vertical planes, so that the camera can capture the surrounding environment more comprehensively and navigate more accurately.

[0008] Preferably, a fixing frame is provided on the turntable, and the camera bracket and the second motor are arranged on the fixing frame.

[0009] Preferably, the fixing frame includes a base and mounting posts arranged on both sides of the base, and the camera bracket is rotatably connected between the two mounting posts.

[0010] The camera bracket is rotatably connected between the two mounting posts so that the camera bracket can be stably supported and has sufficient rotation space in the vertical direction.

[0011] Preferably, the second motor is arranged in a mounting column.

[0012] The second motor is arranged in the mounting column to avoid long-term exposure to the outside and accumulation of dust, which would affect its normal operation.

[0013] Preferably, the camera bracket and the rotating shaft connected to the mounting column are provided with matching limiting mechanisms for limiting the rotation angle of the camera bracket.

[0014] Setting a limit mechanism to restrict the rotation angle of the camera bracket can make the camera rotate within the effective range and avoid invalid rotation. For example, the body image taken by the camera when it turns to the body of the automatic guided vehicle cannot be used for navigation. Limiting the rotation angle can also prevent the line from being broken by winding.

[0015] Preferably, the camera bracket is provided with a plurality of heat dissipation holes.

[0016] Heat dissipation holes are set to facilitate heat dissipation of the camera.

[0017] Preferably, the output shaft of the first motor is provided with a gear, the turntable comprises an inner ring and an outer ring, the inner ring is rotatably connected inside the outer ring, and the inner wall of the inner ring is provided with teeth meshing with the gear.

[0018] Through the above arrangement, the gears are placed in the inner ring of the turntable to avoid being exposed to the outside and damaged by bumps, thereby better protecting the gears.

[0019] Preferably, a camera is installed in the camera bracket, and the center of the camera is located on the axis of the turntable.

[0020] The center point of the camera coincides with the center axis of the turntable, so that the rotation position of the camera can be controlled more accurately through the motor. If it is an eccentric connection, it is more complicated to control the rotation position of the camera.

[0021] Beneficial effects: Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging a camera bracket and a second motor for driving the rotation of the turntable on the turntable, the camera bracket and the rotation axis of the turntable are perpendicular to each other, so that the camera can rotate in the horizontal and vertical planes, and can more comprehensively capture the surrounding environment for navigation.

A gear is provided on the output shaft of the first motor 2. Teeth meshing with the gear are provided on the inner wall of the inner ring 1-1. The inner ring 1-1 is driven to rotate by the first motor 2. Of course, it is also possible to not distinguish between inner and outer rings, and simply provide a through hole in the middle of the turntable 1, and teeth meshing with the gear are provided in the through hole. In this case, the turntable 1 is rotatably connected to the body of the automatic guided vehicle. A fixing frame 5 is connected to the inner ring 1-1, and the camera bracket 3 and the second motor 4 are provided on the fixing frame 5.
