Description

Technical Field

[0001] The present application relates to the field of robotics technology, and in particular to a robot chassis and a robot. Background Art

[0002] With the development of the times, robots are gradually being applied to various fields of industry and life, such as inspection, restaurant delivery and other scenarios.

[0003] The robot chassis is a key component in executing robot movements, significantly impacting its maneuverability and stability. A key indicator of chassis performance is the contact strength of the driving wheels. This is particularly true for dual-drive differential chassis. Because the robot's forward, backward, turning, and pivoting movements require the coordinated operation of both driving wheels, if one wheel leaves the ground, power is lost. Therefore, preventing the driving wheels from becoming suspended in the air is a significant technical challenge for dual-drive differential chassis.

[0004] Therefore, the present application is devoted to designing a robot chassis and a robot. Through reasonable structural design, the robot chassis and the robot have a simple structure and can effectively reduce the slippage of the drive wheels. Summary of the Invention

[0005] The purpose of this application is to provide a robot chassis and a robot, wherein the robot chassis and the robot have a simple structure and the driving wheels have good landing performance.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] A robot chassis comprises a chassis frame, a front travel system, and a rear travel system. The front travel system comprises a pair of front drive wheels and drive wheel brackets connected to the front drive wheels, the front drive wheels being bolted to the drive wheel brackets, which are also bolted to the chassis frame. The front drive wheels and drive wheel brackets are symmetrically arranged on either side of the chassis frame. The rear travel system comprises a pair of driven wheels, driven wheel connecting rods, connecting rod supports, and screws. The driven wheels are symmetrically arranged on either side of the chassis frame.

[0008] Furthermore, the driven wheel is fixed to both ends of the driven wheel connecting rod by bolts respectively, the driven wheel connecting rod is hinged to the connecting rod support by a screw, the driven wheel connecting rod can rotate relative to the connecting rod support around the screw, and the connecting rod support is fixed to the chassis frame by bolts.

[0009] Furthermore, the driven wheel is a universal wheel.

[0010] In addition, the present application also provides a robot, comprising the wheeled robot chassis provided above.

[0011] The robot chassis and robot provided in this application have a reasonable structural design, and the robot chassis and robot drive wheels always maintain effective contact with the ground, thereby improving the landing performance of the drive wheels and effectively reducing the occurrence of drive wheel slippage.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] like Figures 1 to 3As shown, the present application provides a robot chassis, which includes: a chassis frame 100, a front travel system 200, and a rear travel system 300. The front travel system 200 includes: a pair of front drive wheels 210 and drive wheel brackets 220 respectively connected to the front drive wheels 210. The front drive wheels 210 are fixed to the drive wheel brackets 220 by bolts, and the drive wheel brackets 220 are fixed to the chassis frame 100 by bolts. The front drive wheels 210 and the drive wheel brackets 220 are respectively arranged symmetrically on both sides of the chassis frame 100. The rear travel system 300 includes: a pair of driven wheels 310, driven wheel connecting rods 320, connecting rod supports 330, and screws 340. The driven wheels 310 are symmetrically arranged on both sides of the chassis frame 100.

[0023] Furthermore, the pair of driven wheels 310 are respectively fixed to the two ends of the driven wheel connecting rod 320 by bolts, and the driven wheel connecting rod 320 is hinged to the connecting rod support 330 by a screw 340. The driven wheel connecting rod 320 can rotate relative to the connecting rod support 330 around the screw 340, that is, the driven wheel 310 can rotate relative to the connecting rod support 330 around the screw 340, and the connecting rod support 330 is fixed to the chassis frame 100 by bolts.

[0024] Furthermore, the driven wheel 310 is a universal wheel.

[0025] Combine Figure 3 , further illustrating the advantages of the robot chassis of the disclosed embodiment. Since the front drive wheel 210 and the connecting rod support 330 are fixed to the chassis frame 100, the driven wheel 310 can rotate relative to the connecting rod support 330 around the screw 340, that is, the driven wheel 310 can rotate relative to the chassis frame 100 or the front drive wheel 210. When a load is added to the chassis frame 100, the weight of the load will be distributed to the front drive wheel 210 and the rear driven wheel 310. When the ground is uneven, assuming that one of the front drive wheels 210 is suspended, the front drive wheel 210 can rotate relative to the driven wheel 310 due to the weight of the load, so that the suspended front drive wheel 210 comes into contact with the ground, thereby preventing the front drive wheel 210 from being suspended.

[0026] In addition, the present application also provides a robot, which includes the above-mentioned robot chassis. The robot of the embodiment of the present disclosure has the same advantages as the robot chassis of the embodiment of the present disclosure.
