However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Example 1

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a chassis assembly of a robot, comprising a chassis 1, two groups of first fixing frames 2 are symmetrically arranged at the top and bottom ends of the chassis 1, two first dampers 3 are fixedly connected to one side of the first fixing frame 2, a first spring 4 is sleeved on the outer side of the first damper 3, a protective baffle 5 is fixedly connected to one end of the first damper 3, second fixing frames 6 are symmetrically arranged on both sides of the top of the chassis 1, two second dampers 7 are arranged on one side of the second fixing frame 6, a second spring 8 is sleeved on the outer side of the second damper 7, one end of the second damper 7 is fixedly connected to a mounting frame 9, and two auxiliary wheels 10 are rotatably connected to the inner side of the mounting frame 9.

[0025] In this embodiment, the two protective baffles 5 can be respectively fixed on the front and rear ends of the chassis 1 through the first fixing frame 2, and the first damper 3 and the first spring 4 can absorb and reduce the vibration caused by the collision, thereby reducing the damage to the chassis 1 caused by the collision. The two sets of mounting frames 9 can also be respectively fixed on the left and right sides of the chassis 1 through the second fixing frame 6, and the second damper 7 and the second spring 8 can also absorb and reduce the impact of the forces on the chassis 1 on both sides. At the same time, the mounting frames 9 are attached to the surfaces of objects on both sides and rotate, so that the robot can maintain stable movement in a narrow environment and avoid rollover due to squeezing and bumping, thereby improving the protection performance of the robot chassis, improving the stability of the robot during movement, greatly reducing the probability of damage to the chassis 1, and extending the overall service life of the robot.

[0026] Example 2

[0027] like Figure 1-Figure 4 As shown, a protective cover 11 is provided on the top of the chassis 1, vents 12 are provided on both sides of the protective cover 11, an air outlet 13 is provided on the top of the protective cover 11, a cooling fan 14 is provided on the top of the protective cover 11, and the cooling fan 14 is arranged above the air outlet 13. A dust cover 15 is provided on the top of the protective cover 11, a first bearing seat 16 is provided on the top of the chassis 1, a motor 17 is provided on one side of the first bearing seat 16, an output end of the motor 17 movably passes through the first bearing seat 16 and is connected to a first gear 18, and the outer side of the first gear 18 is meshedly connected to a second gear 1 9, both sides of the second gear 19 are connected with a transmission rod 20, one end of the transmission rod 20 is connected with a first differential 21, both ends of the first differential 21 are connected with a steering wheel 22, the other end of the transmission rod 20 is connected with a second differential 23, both ends of the second differential 23 are connected with a driving wheel 24, two second bearing seats 25 are arranged on the top of the chassis 1, a movable rod 26 is movably mounted on the inner side of the second bearing seat 25, both ends of the movable rod 26 are arranged with an ear seat 27, the inner side of the ear seat 27 is rotatably connected with a connecting rod 28, one end of the connecting rod 28 is connected to the steering wheel 22.

[0028] In this embodiment, the protective cover 11 can be used to protect important components on the chassis 1, and the vents 12 can be used to maintain normal ventilation. The heat generated by the components in the protective cover 11 during operation can be quickly discharged through the cooling fan 14. The dust cover 15 can prevent dust from falling and causing damage to the cooling fan 14 or components, thereby improving the heat dissipation performance, preventing important components from being damaged, and extending the service life of the robot.

The movable rod 26 slides on the second bearing seat 25, prompting the connecting rod 28 to rotate on the ear seat 27, thereby making the steering of the steering wheel 22 more stable and smooth, and further improving the stability of the chassis 1.

[0029] The working principle of this embodiment is as follows: when in use, first start the cooling fan 14 to absorb the heat generated by the operation of the important components in the protective cover 11 through the air outlet 13 and discharge it to the outside. Then, when the chassis 1 collides or is collided, the force at the collision position will be transmitted to the first damper 3 and the first spring 4 through the protective baffle 5, causing the first damper 3 and the first spring 4 to shrink quickly, absorb and reduce the impact force, and maintain the stability of the chassis 1. Finally, when the robot moves in a narrow environment, the auxiliary wheel 10 will rotate in contact with the surfaces of the objects on both sides to maintain the stable movement of the robot. At the same time, the second damper 7 and the second spring 8 will repeatedly shrink and rebound due to the irregularity of the surface of the object, absorb and reduce the vibration, and maintain the stability of the chassis 1, thereby completing the use of the robot chassis assembly.
