Please refer to fig. 2, fig. 3, and fig. 6 to fig. 9. The plurality of driving wheel sets 40 may be, but are not limited to, disposed in pairs at opposite sides of the frame body 120, and constitute the chassis module 2 of the inspection robot 1 with the frame body 120. Each drive wheel set 40 includes a bracket assembly 410, a steering module 420, a cushion assembly 430, and drive wheels 440. The bracket assembly 410 includes a fixing frame 411 and a supporting frame 412. The fixing frame 411 is detachably disposed on the box 121 of the frame main body 120, and includes a vertical section 4111, and a first bending section 4112 and a second bending section 4113 bent from two opposite ends of the vertical section 4111.

At this time, the first bending section 4112 extends outward from the side close to the box 121, and the supporting frame 412 is pivotally connected to an end of the first bending section 4112 extending outward.

The first bending section 4112 includes a plurality of branches 4112a. The plurality of branches 4112a may be formed by bending directly from the vertical section 4111, and arranged at intervals in the short side direction of the vertical section 4111; or is formed by bifurcating an end extending outward from the first bending section 4112. The support frame 412 may be, but is not limited to, a disc 4121 having a circular cutout structure, and has a first axial direction z extending along the center of the disc 4121. Meanwhile, the tray 4121 is pivotally connected to the corresponding branch 4112a through the shaft 4122 disposed at two opposite sides thereof, and has a second axial direction x extending along the axial direction of the shaft 4122, so that the supporting frame 412 can swing around the second axial direction x on the first bending section 4112.

The steering module 420 includes a flange 421 and a steering actuator 422. The flange 421 is movably disposed in the tray 4121 of the supporting frame 412 through a hollow structure. The steering actuator 422 is fixed to a disc 4121, which includes a speed reducer and a motor. An output shaft of the speed reducer is connected to the flange 421, and an output end (output shaft) of the motor is connected to the rotating shaft 431 of the buffering assembly 430, so as to drive the buffering assembly 430 to rotate around the first axial direction z. The buffer assembly 430 has a rotation shaft 431 at one end thereof and a damping unit 432 at the other end thereof. The damping unit 432 includes a connection structure 4321 and two dampers 4322 arranged side by side, wherein the two dampers 4322 are connected to the connection structure 4321 at intervals, and the rotation shaft 431 is disposed on the connection structure 4321 and between the two dampers 4322.

The shock absorber 4322 comprises a movable part 4323 and a buffer part 4324, and the connecting structure 4321 is bridged between the movable part 4323 and/or the buffer part 4324 of the two shock absorbers 4322. One end of the movable member 4323 penetrates through the buffer member 4324 and can reciprocate relative to the buffer member 4324. In some embodiments of the present application, the damper can be a shock absorbing device of a shock absorbing cylinder, an air cylinder or an inner spring, and one end of the damper is connected to the driving wheel 440, so that the driving wheel 440 can be reciprocally displaced along the first axis z by the damper 4322, and a shock absorbing effect can be provided between the frame body 120 and the driving wheel 440. Meanwhile, the fork structure formed by the two side-by-side dampers 4322 can transmit torque while achieving shock absorption.

The driving wheel 440 may be a damper 432 directly connected to the damper assembly 430, or a damper 4324 connected to the damper 432 through a fixing assembly 442 provided on a shaft center 441a of a hub motor 441 thereof. The fixing assembly 442 includes a fixing member 4421 and an adaptor 4422 which can be combined with each other, and a matching groove 4423 is provided on the fixing member 4421 and the adaptor 4422. The fixing member 4421 and the adaptor 4422 are coupled to each other at the axial center 441a of the hub motor 441 through the side provided with the groove 4423, so that the axial center 441a is inserted between the fixing member 4421 and the adaptor 4422 and can rotate relative to the fixing assembly 442.

Therefore, in the embodiment of the present application, since each driving wheel 440 can rotate independently, the chassis characteristic of four-wheel and four-turn can be provided, and the use requirements of different environments can be met by the operation of different driving wheels 440. Meanwhile, under the driving of the steering module 420, the driving wheel 440 has the characteristic of moving in multiple directions, so that the inspection robot has a flexible chassis movement form, for example, the inspection robot 1 can perform a movement mode of rotating at the origin and having a wedge-shaped situation, so as to perform work tasks under different terrains and paths.

In some embodiments of the present application, the bracket assembly 410 further includes a link 413 having opposing first and second ends 4131, 4132. The first end 4131 of the connecting rod 413 is pivotally connected to the second bending section 4113 of the fixing frame 411 and can swing around the second axial direction x. The second end 4132 of the connecting rod 413 is movably connected to the adaptor 4422 on the driving wheel 440, so that the driving wheel 440 can rotate around the third axis y relative to the second end 4132 through the adaptor 4422. For example, the second end 4132 of the link 413 and the adaptor 4422 may be provided with cooperating spherical bearings 414, such that the adaptor 4422 may rotate in multiple directions relative to the second end 4132 of the link 413, thereby allowing the drive wheel 440 to make small steering changes between multiple axial directions under the driving of the steering module 420 and the shock absorber 432.

Meanwhile, in the present embodiment, the link pushes the driving wheel 440 outward to a predetermined distance, such that one end of the cushion member 430 is connected to the steering module 420 at a side close to the frame body 120 and the other end is connected to the driving wheel 440 at a side away from the frame body 120 in an inclined manner, i.e., one end of the driving wheel group 40 is connected to the frame body 120 and the other end is inclined from the side close to the frame body 120 toward the side away from the frame body 120, thereby exhibiting an inclined configuration in which the upper end is inward (i.e., close to the frame body) and the lower end is outward (i.e., away from the frame body) as a whole. In this way, the shock absorber 432 of the buffering assembly 430 can not only resist the impact force from the vertical direction of the ground, but also resist the acting force in the lateral direction, thereby providing a multi-aspect shock absorption effect.

Wherein the angle of inclination of the damping assembly 430 may be, but is not limited to, in the range of about 5 degrees to 20 degrees, such as an angle of inclination of 10 degrees. The tilt angle can be adjusted according to different types of tires 443 disposed on the driving wheel 440. Further, the adjustment may be performed according to the size of the case 121 of the carriage body 120. That is, in the embodiment of the present application, since the driving wheel set 40 integrates multiple functions of steering and driving, the track width and/or the wheel base can be changed according to the size of the box 121, and the inclination angle of the damping assembly can be changed, so that the chassis module 2 with different sizes can be used.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
