[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-3 The body protection structure of the quadruped robot body includes a quadruped robot body 1, and the top wall of the quadruped robot body 1 is provided with a support structure 2, and the support structure 2 includes a baffle 201 arranged on the top of the quadruped robot body 1, and the baffle 201 is at a certain distance from the top wall of the quadruped robot body 1. When an object falls through the baffle 201, it can be protected to a certain extent. A first spring 203 is arranged on the side of the baffle 201 close to the top wall of the quadruped robot body 1, and the side of the first spring 203 away from the baffle 201 is fixedly connected to the top wall of the quadruped robot body 1. When the baffle 201 receives the falling object, the elasticity of the first spring 203 is used to reduce the damage to the quadruped robot body 1, and the elastic effect of the first spring 203 is set according to the force condition of the quadruped robot body 1.

[0029] A contact block 206 is provided on one side of the baffle 201 close to the top wall of the quadruped robot body 1, and the contact block 206 is located at the exact center of the baffle 201. When the baffle 201 is forced to move downward, the contact block 206 is driven to move downward. A switch 207 is installed on the top wall of the quadruped robot body 1, and the switch 207 and the contact block 206 are in the same vertical plane. An electric telescopic rod 208 is provided on the bottom wall of the quadruped robot body 1, and the electric telescopic rod 208 is electrically connected to the switch 207. During the downward movement of the abutment block 206, it abuts against the switch 207, and the electric telescopic rod 208 is started by the switch 207. The electric telescopic rod 208 is a four-section telescopic rod, and the model is WSD30-200-4.

[0030] A circular plate 202 is installed on the side of the baffle 201 close to the quadruped robot body 1. There are four circular plates 202, which are symmetrically distributed at the four corners of the baffle 201. The side of the circular plate 202 away from the baffle 201 is fixedly connected to the outer wall of the first spring 203. There are four first springs 203, which are symmetrically distributed at the four corners of the top wall of the quadruped robot body 1. The inclined plate and the four first springs 203 are set to improve the balance of the baffle 201 falling after being subjected to force.

[0031] A connecting plate 204 is installed on the outer wall of the circular plate 202, and a balancing plate 205 is installed on the outer wall of the connecting plate 204. The bottom wall of the balancing plate 205 is close to the top wall of the baffle 201, and the side of the balancing plate 205 away from the baffle 201 is fixedly connected to the bottom wall of the abutment block 206. The balancing plate 205 is located at the exact center of the baffle 201. The abutment block 206 is driven to move downward by the connecting plate 204 and the balancing plate 205, thereby further improving the balance of the baffle 201 when it falls after being subjected to force.

[0032] When an object falls or an object that is too heavy is placed on the top wall of the baffle 201, the baffle 201 is forced to move downward, and at the same time drives the circular plate 202, the connecting plate 204 and the balance plate 205 to apply pressure to the first spring 203. During the contraction of the first spring 203, the abutment block 206 is driven to touch the switch 207. After the switch 207 is turned on, the electric telescopic rod 208 is started to move downward, providing certain support to the quadruped robot body 1 to reduce damage to the quadruped robot body 1.

[0033] Reference Figure 1 and Figure 4The bottom wall of the body of the quadruped robot body 1 is provided with an adjustment structure 3, and the adjustment structure 3 includes a connecting piece 301 installed on the bottom wall of the body of the quadruped robot body 1, and the inner wall of the connecting piece 301 is movably connected with the outer wall of the electric telescopic rod 208, and the electric telescopic rod 208 is located at the inner center position of the two connecting pieces 301. The outer wall of the connecting piece 301 is installed with a motor 302, and the output end of the motor 302 is rotatably connected with the inner wall of the electric telescopic rod 208, and the output end of the motor 302 is connected to the supporting structure of the connecting piece 301 2 and the electric telescopic rod 208 are rotatably connected, and the electric telescopic rod 208 is driven to rotate by starting the motor 302, so that the electric telescopic rod 208 is as close to the bottom wall of the body of the quadruped robot body 1 as possible, so as to avoid placing the electric telescopic rod 208 horizontally when not in use, so as not to affect its operation, and the motor 302 is electrically connected to the switch 207. When the switch 207 is turned on, the motor 302 is started to rotate the electric telescopic rod 208 to a state vertical to the ground, and then the electric telescopic rod 208 is started to operate.

[0034] An L-shaped plate 303 is installed at the telescopic end of the electric telescopic rod 208, and three L-shaped plates 303 are equidistantly distributed at the telescopic end of the electric telescopic rod 208. A fixed plate 304 is installed at the bottom wall of the L-shaped plate 303, and a second spring 305 is installed at the bottom wall of the fixed plate 304. A buffer pad 306 is installed at the bottom wall of the second spring 305. The six second springs 305 are equidistantly distributed around the circumference of the fixed plate 304. The motor 302 is started by the switch 207. After the output end of the motor 302 drives the electric telescopic rod 208 to rotate to a vertical horizontal state, the electric telescopic rod 208 is started to move downward, driving the L-shaped plate 303, the fixed plate 304, the second spring 305 and the buffer pad 306 to move at the same time, and making the buffer pad 306 abut against the ground. When subjected to force, the second spring 305 and the buffer pad 306 are used to start a certain buffering effect.

[0035] The outer wall of the baffle 201 is installed with an inclined plate 4. There are two inclined plates 4, which are symmetrically distributed on both sides of the baffle 201. Through the inclined plate 4, when an object falls on the baffle 201, the object can slide down to a certain extent through the inclined plate 4 and the first spring 203, utilizing the elastic force of the first spring 203 and the inclination of the inclined plate 4.

[0036] Working principle:

[0037] When an object falls or an object that is too heavy is placed on the top wall of the baffle 201, the baffle 201 is forced to move downward, and at the same time drives the circular plate 202, the connecting plate 204 and the balance plate 205 to apply pressure to the first spring 203. During the contraction of the first spring 203, the abutment block 206 is driven to touch the switch 207. After the switch 207 is turned on, the electric telescopic rod 208 is started to move downward, providing certain support to the quadruped robot body 1 to reduce damage to the quadruped robot body 1.

[0038] The motor 302 is started by the switch 207. After the output end of the motor 302 drives the electric telescopic rod 208 to rotate to a vertical horizontal state, the electric telescopic rod 208 is started to move downward, driving the L-shaped plate 303, the fixed plate 304, the second spring 305 and the buffer pad 306 to move simultaneously, and the buffer pad 306 is made to contact with the ground. When subjected to force, the second spring 305 and the buffer pad 306 are used to play a certain buffering role.
