Description

Technical Field

[0001] This utility model relates to the field of mobile robot technology, specifically a lightweight steering wheel system for the movement of intelligent devices. Background Technology

[0002] As various intelligent products enter the market and the intelligent manufacturing field matures, logistics and transportation, as a key link in this field, are bound to become a major focus within the industry. Currently, steering wheel products, as the driving units of mobile robots, have begun to be mass-produced and marketed, leading to many common problems that, to some extent, constrain further market expansion. An existing integrated steering wheel system with a driver (announcement number: CN221585103U) has revealed at least the following defects in use:

[0003] In practical use, especially in the work environment of interior decoration, mobile robots using this steering wheel system often face uneven ground environments, which inevitably causes the steering wheels to bounce during use. Since mobile robots often have many precision components inside, the bounce may cause poor contact of the components, affecting the normal operation of the robot. Therefore, a lightweight steering wheel system for the movement of intelligent devices is needed. Utility Model Content

[0004] The main objective of this invention is to provide a lightweight steering wheel system for the movement of intelligent devices, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lightweight steering wheel system for moving smart devices includes a support frame composed of multiple segmented frames. A mounting plate is fixedly connected to the inner walls of each of the segmented frames on the outer side of the support frame. A bearing mounting seat is rotatably connected to the bottom side of each mounting plate. Multiple piston tubes are fixedly connected to the bottom side of each bearing mounting seat. A steering wheel support plate is fixedly connected to the bottom end of all the piston tubes. A rubber wheel is rotatably connected to one side of the steering wheel support plate. Multiple shock-absorbing springs are arranged between the steering wheel support plate and the bottom side of the bearing mounting seat. Each shock-absorbing spring corresponds to one piston tube, and each shock-absorbing spring is wound around the outside of the corresponding piston tube.

[0007] Preferably, a cross roller bearing protective shell is fixedly connected to the top side of the bearing mounting base, a cross roller bearing is rotatably connected to the bottom inner wall of the cross roller bearing protective shell, and the top end of the cross roller bearing communicates with the outside of the top outer wall of the cross roller bearing protective shell.

[0008] Preferably, a cross bearing mounting post is rotatably connected to the top side of the cross roller bearing protective housing, and the bottom end of the cross bearing mounting post is fixedly connected to the top end of the cross roller bearing, while the top end of the cross bearing mounting post is rotatably connected to the mounting plate.

[0009] Preferably, a servo motor is fixedly connected to the top of the mounting plate, and the output end of the servo motor is connected to the top of the cross bearing mounting post.

[0010] Preferably, a side frame is fixedly connected to the bottom side of the outer edge of the support frame, and a side protective plate is fixedly connected to each end of the side frame. The top side of each side protective plate is fixedly connected to the bottom side of the support frame, and each side protective plate partially surrounds the corresponding rubber wheel.

[0011] Preferably, a steering wheel body is fixedly connected to the inner wall of each steering wheel support plate, and the output end of each steering wheel body is fixedly connected to the corresponding rubber wheel. A laser rangefinder is installed on the bottom side of each mounting plate, and each laser rangefinder is electrically connected to the corresponding servo motor and steering wheel body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By using shock-absorbing springs and piston tubes, a damping structure is formed, which converts the energy generated by vibration into heat generated by the compression of air inside the piston tube. This prevents the robot body supported on the steering wheel from reciprocating due to vibration. The shock-absorbing springs also allow the steering wheel to quickly return to its original position, thus preventing reciprocating vibration from causing the precision components inside the robot to become loose and extending the service life of the device.
