The threaded slider 21 is movably inserted in the sliding groove 26, so that the rubber pad 24 contacts the ground, thereby increasing the friction, thereby improving the timely stopping of the device on a smooth slope, and avoiding a series of losses.

[0021] A symmetrically distributed shock-absorbing groove 4 is provided at the bottom end of the base 11, and two driving components 12 are movably inserted in the shock-absorbing groove 4. A spring shock absorber 41 is installed on the inner wall of the shock-absorbing groove 4, and the end of the spring shock absorber 41 is fixedly connected to the driving component 12. A fixing plate 42 is fixed on the inner wall of the shock-absorbing groove 4, and a No. 2 spring shock absorber 43 is installed on the top of the fixing plate 42. The top of the No. 2 spring shock absorber 43 is fixedly connected to the driving component 12.

[0023] A protection pad 15 is installed at the bottom end of the base 11 .

[0024] By adopting the above technical solution, the bottom end of the base 11 can be protected.

[0025] The base 11 is mounted on the bottom end of the robot body 1 by screws.

[0026] By adopting the above technical solution, the base 11 can be easily installed and disassembled.

[0027] A placement box 14 is installed outside the robot body 1.

[0028] By adopting the above technical solution, the placement box 14 can be used to conveniently place some brochures and the like for customers to view.

[0029] A fixing frame 3 is fixedly provided on the inner wall of the base 11 , and a worm 31 is rotatably provided in the fixing frame 3 .

[0030] By adopting the above technical solution, the fixing frame 3 can install and position the worm 31 .

[0031] A worm gear 32 is fixedly provided on the outer side of the bidirectional threaded rod 2 , and the worm 31 and the worm gear 32 are meshed with each other.

[0032] By adopting the above technical solution, the worm 31 rotates to drive the mutually meshing worm wheels 32 to rotate.

[0033] A motor 33 is installed outside the fixing frame 3 , and the output shaft end of the motor 33 is inserted through the fixing frame 3 and fixedly connected to the worm 31 .

[0035] Working principle: When the reception robot encounters an uneven road surface during driving, it will generate impact force. At this time, the No. 1 spring shock absorber 41 and the No. 2 spring shock absorber 43 store and release energy by compressing and stretching the springs. At the same time, the damping system is combined to slow down the vibration, thereby effectively absorbing the impact force and reducing the upward and downward shaking forces respectively, so as to achieve the effect of shock absorption. When the reception robot stops on an uphill or downhill slope, if the ground is too smooth, the reception robot may slide along with the trend, etc., causing collision and damage to the equipment. At this time, after the vehicle stops, the control system in the reception robot turns on the motor 33, so that the motor 33 starts to work, and the electric The rotation of the output shaft end of the machine 33 drives the worm 31 to rotate, and the rotation of the worm 31 drives the mutually meshing worm gear 32 to rotate, and the rotation of the worm gear 32 drives the bidirectional threaded rod 2 to rotate. The rotation of the bidirectional threaded rod 2 drives the two threaded sliders 21 to move to both sides under the limit of the sliding groove 26. The movement of the threaded slider 21 through the limit of the sliding groove 26 drives the operating panel 25 to rotate on the rotating rod 22, thereby allowing the two rotating frames 23 to swing to both sides, thereby allowing the rubber pad 24 to be used for ground contact and, through the contact between the rubber pad 24 and the ground, the friction can be increased to prevent the reception robot from sliding along when the ground is too smooth, thereby causing equipment damage, etc.

[0036] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
