Description

Technical Field

[0001] The utility model relates to the technical field of AGV vehicles, in particular to an AGV vehicle chassis. Background Technique

[0002] With the continuous development of society, AGV vehicles are widely used in many places such as manufacturing, warehousing and airports. The front end of existing automatically driving AGV vehicles is equipped with a path detection and monitoring structure. Conventional AGV vehicles make the path detection and monitoring structure cooperate with a blind spot compensation device to regulate and adjust the driving routes of vehicles and models. Most existing blind spot compensation devices achieve the blind spot compensation function by installing lidar, but there are still problems with inconvenient adjustment of the radar angle. For this reason, technical personnel in this field have proposed an AGV vehicle chassis to solve the problems raised in the above background. Content of the Utility Model

[0003] The purpose of the utility model is to provide an AGV vehicle chassis to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution:

[0005] An AGV vehicle chassis includes a vehicle body chassis. A cross plate is installed at the front end of the vehicle body chassis. Two vertical plates are symmetrically connected to the top of the cross plate. A bidirectional threaded rod is rotatably connected between the two vertical plates. Two threaded sliders are symmetrically connected to the bidirectional threaded rod. A first driving member is installed on the outer side wall of one of the vertical plates. One end of the bidirectional threaded rod is connected to the output end of the first driving member. The bottom end of the threaded slider is slidably attached to the top of the cross plate. The top end of the threaded slider is movably connected to the bottom of a support plate. The top of the support plate is movably connected to the outer wall of one side of a lifting frame. An adjustment frame is installed in the lifting frame, and the angle of the adjustment frame in the lifting frame is adjustable. A clamping assembly is installed inside the lifting frame. A blind spot compensation radar is clamped and installed inside the clamping assembly, and the clamping assembly can rotate inside the adjustment frame.

[0006] As a further solution of the utility model: The bottom end of the support plate is rotatably connected to one end of a first connecting plate, and the other end of the first connecting plate is fixedly connected to the top end of the corresponding threaded slider. The top end of the support plate is rotatably connected to one end of a second connecting plate, and the other end of the second connecting plate is fixedly connected to the outer wall of one side of the lifting frame.

[0007] As a still further solution of the utility model: Two support plates are symmetrically connected to the top end of one of the threaded sliders.

[0008] As a further solution of the present utility model: One end of each of the two outer walls of the adjustment frame is connected to one end of two first rotating rods, the other end of the first rotating rod is rotatably connected to the inner wall of the lifting frame, a second driving member is installed on one outer wall of the lifting frame, and one end of one of the first rotating rods is connected to the output end of the second driving member.

[0009] As a further solution of the present utility model: The clamping assembly includes a rotating plate, a fixed clamping plate fixedly connected to the top end of the rotating plate, and a movable clamping plate installed on the fixed clamping plate. The blind spot radar is clamped between the fixed clamping plate and the movable clamping plate. A third driving member is installed at the bottom end of the adjusting plate, the output end of the third driving member is connected to the bottom end of the second rotating rod, and the top end of the second rotating rod is connected to the bottom end of the rotating plate.

[0010] As a further solution of the present utility model: Anti-slip layers are installed on the inner circumferences of the fixed clamping plate and the movable clamping plate.

[0011] The present utility model has the following advantages: The height of the lifting frame is adjusted through the cooperation of the bidirectional threaded rod, the threaded slider, and the support plate, and then the height of the blind spot radar is adjusted. The angle of the adjustment frame is adjusted through the lifting frame, and the rotation of the clamping assembly is coordinated, so that the angle of the blind spot radar can be adjusted. When the vehicle chassis travels on rough ground or turns, the blind spot radar can be adjusted severely to detect the road conditions, and then it can be used in cooperation with the monitoring structure in the automatic driving system, which can better observe the visual blind area and improve the driving stability of the vehicle chassis.
