Specific embodiments

[0021] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0022] Among them, the same reference numerals in the drawings all refer to the same components.

[0023] Embodiment 1

[0024] As Figure 1 shown, it includes a base block 1. Positioning grooves 2 are provided at the four corners of the base block 1. The bottom sides of the same-side positioning grooves 2 are jointly connected with an arc connection block 3. Fixed blocks 4 are provided on both sides of the top of the arc connection block 3. The fixed blocks 4 are clamped inside the positioning grooves 2. A fixed groove 5 is opened on one side of the positioning groove 2. A driving device 6 is connected and arranged inside the fixed groove 5. Connecting blocks 7 are provided at both ends of the arc connection block 3. A transmission hole 8 is penetrated through one side of the connecting block 7. A transmission shaft 9 is jointly connected inside the same-direction transmission holes 8. An arc connection frame 10 is connected to the surface of the transmission shaft 9. Shock absorbers 11 are connected to both ends of the arc connection frame 10. The two ends of the shock absorbers 11 are connected to the two ends of the fixed blocks 4. A connecting bearing 12 is sleeved in the middle of the arc connection frame 10. A support rod 13 is connected to the surface of the connecting bearing 12. A connecting roller 14 is provided at one end of the support rod 13. A first electric telescopic rod 15 is provided on the surface of the support rod 13. The first electric telescopic rod 15 is connected to the fixed block 4.

[0025] Furthermore, a connecting hole 16 is penetrated through the top of the base block 1 between the two positioning grooves 2. A connecting screw hole 17 is provided on the top surface of the arc connection block 3. During installation, it is aligned and fixed by bolts, and the arc connection block 3 is connected to the fixed block 1.

[0026] An arc strengthening block 18 is provided between the two fixed blocks 4 on the same side. By providing the arc strengthening block 18, the mutual support ability of the fixed blocks 4 can be strengthened, so that the arc connection frame 10 can effectively provide support when being impacted.

[0027] As Figure 2 shown, one side of the arc-shaped connecting block 3 is provided with an auxiliary rod 19. One end of the auxiliary rod 19 is connected to the arc-shaped connecting block 3 through a connecting rotating shaft 20. The middle of the auxiliary rod 19 is connected with a second electric telescopic rod 21. The other end of the second electric telescopic rod 21 is connected to the arc-shaped connecting block 3. An auxiliary wheel 22 is arranged at the bottom of the auxiliary rod 19. By extending and contracting the second electric telescopic rod 21, the distance that the auxiliary rod 19 extends outward on both sides of the base block 1 can be controlled. When the extension amplitude is larger, the ability of the robot to prevent tipping to both sides can be strengthened.

[0028] The auxiliary rod 19 is bent. The bent shape can make the stability of the auxiliary rod 19 higher. When the robot is tilted, the auxiliary rod 19 can provide effective support.

[0029] The arc-shaped connecting block 3 is hollow. Being set as hollow can reduce the mass of the arc-shaped connecting block 3 and make the overall robot lighter after installation.

[0030] One side of the arc-shaped connecting frame 10 is provided with a stop block 23.

[0031] As Figure 3 shown, the bottoms of two arc-shaped connecting blocks 3 are jointly connected with a reinforcing rod 24. The arranged reinforcing rod 24 and the arc-shaped reinforcing block 18 can strengthen the overall stability of the arc-shaped connecting block 3.

[0032] Specifically, when the robot runs on an uneven road surface and tips over in the front-back direction, the arc-shaped connecting frame 10 is set to block the tipping. At this time, the arc-shaped connecting frame 10 will contact the ground. The arranged arc-shaped connecting frame 10 is pressed upward through the transmission shaft 9. At this time, the arc-shaped connecting frame 10 is transmitted to the fixed block 4 through the shock absorber 11. The shock absorber 11 reduces the vibration and can provide support for the arc-shaped connecting frame 10. And by extending the first electric telescopic rod 15, it can drive the support rod 13 to rotate around the middle surface of the arc-shaped connecting frame 10 through the connecting bearing 12, so that the support rod 13 extends outward, thereby driving the connecting roller 14 to displace outward, which can prevent tipping in the front-back direction. And when the robot chassis is stuck and tilted, the first electric telescopic rod 15 can be used to drive the support rod 13 to extend outward to pry the robot chassis, facilitating the robot's self-rescue. By extending and contracting the second electric telescopic rod 21, the distance that the auxiliary rod 19 extends outward on both sides of the base block 1 can be controlled. When the extension amplitude is larger, the ability to prevent the robot from tipping to both sides can be strengthened.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
