[0021] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0022] Please refer to the attached Figure 1-3 An embodiment of the present application provides a charging robot for an electric vehicle, including a vehicle body 100 and a protective device 200. A wheel set is provided at the bottom of the vehicle body 100 and moves through the wheel set. The protective device 200 is arranged at the rear end of the vehicle body 100 to protect the rear end of the vehicle body 100 and reduce the degree of damage to the charging robot when it is rear-ended. The protective device 200 includes a main protective component and an auxiliary protective component. The main protective component includes a mounting seat, a protective plate 220 and at least one elastic telescopic structure 230. The mounting seat is arranged at the rear end of the vehicle body 100, and the protective plate 220 is arranged on the side of the mounting seat away from the vehicle body 100. The protective plate 220 and the mounting seat are connected by the elastic telescopic structure 230. The telescopic direction of the elastic telescopic structure 230 is parallel to the length direction of the vehicle body 100. The auxiliary protective component is arranged between the protective plate 220 and the mounting seat. The auxiliary protective component includes a guide rod 240, a first elastic member, two sleeves 260 and two linkage members. The guide rod 240 is arranged on the mounting seat. The first elastic member and the two sleeves 260 are movably mounted on the guide rod 240 and the first elastic member is located between the two sleeves 260. The two sleeves 260 are respectively connected to the protective plate 220 through two linkage members.

[0023] When the charging robot is rear-ended, the protective plate 220 will move toward the vehicle body 100 to compress the elastic telescopic structure 230. The elastic telescopic structure 230 will unload the force when compressed, so that the main protective component can protect the vehicle body 100. At the same time, the protective plate 220 will drive the linkage member to move when moving, and the moving linkage member can drive the sleeve 260 to move toward the first elastic member so that the first elastic member is compressed by the two sleeves 260. The first elastic member completes secondary unloading during the compression process. The simultaneous unloading of the main and auxiliary protective components significantly improves the protective performance of the protective device 200 on the rear of the charging robot, meeting the high protection requirements of the charging robot.

[0024] The first elastic member may be, but is not limited to, a first spring 250. The mounting seat may be, but is not limited to, a mounting plate 211. The mounting plate 211 is screwed to the shell of the vehicle body 100 to facilitate maintenance and replacement of the protective device 200.

[0025] In some embodiments of the present application, the elastic telescopic structure 230 includes a telescopic rod 231 and a second elastic member. The ends of the telescopic rod 231 are respectively connected to the protective plate 220 and the mounting base. The second elastic member is sleeved around the outer periphery of the telescopic rod 231. The ends of the second elastic member are respectively in abutment with the protective plate 220 and the mounting base. This elastic telescopic structure 230 is not only simple in structure but also has excellent protective performance.

[0026] The telescopic rod 231 can be a two-section telescopic rod 231, that is, it includes a base rod and a movable rod movably inserted into the base tube. The telescopic rod 231 is a general product and will not be described in detail in this application. The second elastic member can be, but is not limited to, a second spring 232.

[0027] Preferably, there are two elastic telescopic structures 230, and the two elastic telescopic structures 230 are spaced apart along the width direction of the vehicle body 100. In this case, the axial direction of the guide rod 240 can be parallel to the width direction of the vehicle body 100. The auxiliary protection assembly is disposed between the two elastic telescopic structures 230.

[0028] Preferably, two mounting blocks 212 are spaced apart on the side of the mounting plate 211 away from the vehicle body 100 , and both ends of the guide rod 240 are respectively arranged on the two mounting blocks 212 , one end of the base rod is fixed to the mounting block 212 and one end of the movable rod is fixed to the protective plate 220 .

[0029] In some embodiments of the present application, the linkage member is a linkage rod 270, one end of which is rotatably connected to the sleeve 260 and the other end of which is rotatably connected to the protective plate 220. The two linkage rods 270 are arranged in a direction inclined toward each other. The above linkage member has a simple structure and good structural stability.

[0030] Preferably, an inclined mounting rod 261 is further provided on the outer periphery of the sleeve 260 , the end of the linkage rod 270 is rotatably connected to the end of the mounting rod 261 , and the inclination direction of the mounting rod 261 is the same as that of the linkage rod 270 .

[0031] In some embodiments of the present application, a first elastic protection strip is further included, and the first elastic protection strip is disposed at the front end of the vehicle body 100. The first elastic protection strip can be made of rubber or other materials.

[0032] Preferably, the first elastic protection strip is shaped like a convex arc on the side facing away from the vehicle body 100. The arched protrusion of the first elastic protection strip first absorbs the impact force and then disperses it toward both ends, mitigating damage to the vehicle body 100 and providing excellent protection. Furthermore, since the front end of the vehicle body 100 will be equipped with sensors such as LiDAR, the elastic protection strip is relatively small, ensuring sufficient space for the placement of sensors such as LiDAR while providing protection for the front end of the vehicle body 100.

[0033] In some embodiments of the present application, the vehicle body 100 is provided with second elastic protection strips 280 on both sides along the width direction, thereby achieving lateral protection for the vehicle body 100 .

[0034] Preferably, the side of the second elastic protection strip 280 away from the vehicle body 100 is convex in an arc shape. The arched protrusion of the second elastic protection strip 280 first absorbs the impact force and then disperses it to both ends, thereby alleviating damage to the vehicle body 100 caused by the impact and providing better protection. The second elastic protection strip 280 can be made of materials such as rubber.
