The mounting bracket 113 is provided with a waist-shaped hole 1131 extending in the vertical direction of the charging device. The fixed mounting member 231 is provided with a connecting hole 2313. A connecting member connects the fixed mounting member 231 to the mounting bracket 113 via the connecting hole 2313 and the waist-shaped hole 1131. Exemplarily, the number of waist-shaped holes 1131, connecting holes 2313, and connecting members is four, but this is not limiting.

[0046] Reference Figure 4 and Figure 5 as well as Figure 8 and Figure 9 The movable mounting part 232 and the fixed mounting part 231 are spaced apart along the front-to-back direction of the charging device, and the movable mounting part 232 is used to install the charging connector 22. The main guide assembly is connected between the fixed mounting part 231 and the movable mounting part 232. The main guide assembly enables the movable mounting part 232 to be elastically mounted. The main guide assembly is configured to enable the movable mounting part 232 and the charging connector 22 to move along the front-to-back direction of the charging device, swing in the left-right direction, and swing in the up-and-down direction. The charging connector 22 is electrically connected to the charger 70, and the charging connector 22 is used to dock with the mobile robot. When docking with the mobile robot, the charging connector 22 can be displaced in multiple directions to enable the charging connector 22 to dock with the mobile robot accurately, reducing the risk of damage to the charging connector 22 and reducing the positioning accuracy requirements of the mobile robot.

[0047] The main guide assembly includes a hanging elastic member 233 and a main guide elastic member 235. The hanging elastic member 233 is suspended from the upper end of the movable mounting member 232 and is used to balance the gravity of the movable mounting member 232 and the charging connector 22. In this embodiment, a hanging bracket 234 is provided on the fixed mounting member 231, and the hanging bracket 234 is used to mount the hanging elastic member 233. The hanging bracket 234 is Z-shaped. A first fixing hole is provided on the lower plate of the hanging bracket 234, and a second fixing hole 2314 is provided on the fixed mounting member 231. The fixing member 238 connects the lower plate of the hanging bracket 234 to the fixed mounting member 231 via the first and second fixing holes 2314. The upper plate of the hanging bracket 234 is connected to the hanging elastic member 233. A first hanging hole 2341 is provided on the upper plate of the hanging bracket 234, and a second hanging hole 2321 is provided on the movable mounting member 232. One end of the hanging elastic member 233 is connected to the first hanging hole 2341, and the other end is connected to the second hanging hole 2321. In this embodiment, there are two hanging elastic members 233, but this is not limiting. In this embodiment, both hanging elastic members 233 are arranged at an angle, with the ends of the two hanging elastic members 233 connected to the hanging bracket 234 tilted away from each other.

[0048] There are four main guide elastic members 235, each of which is connected between the fixed mounting member 231 and the movable mounting member 232, and the four main guide elastic members 235 are arranged in a 2*2 matrix. Since the main guide elastic members 235 extend along the front-to-back direction of the charging device, the movable mounting member 232 and the charging connector 22 can move along the front-to-back direction of the charging device. Figure 10 , L is the distance that the movable mounting member 232 and the charging connector 22 move forward and backward. Because the four main guide elastic members 235 are arranged in a 2*2 matrix, the four main guide elastic members 235 can be divided into two groups, left and right. When the left group of main guide elastic members 235 is compressed, the movable mounting member 232 and the charging connector 22 swing to the left, and when the right group of main guide elastic members 235 is compressed, the movable mounting member 232 and the charging connector 22 swing to the right. That is, the movable mounting member 232 and the charging connector 22 can swing left and right along the charging device. Figure 11 , θ is the angle at which the movable mounting member 232 and the charging connector 22 swing left and right. The four main guide elastic members 235 can also be divided into two groups, upper and lower. When the upper group of main guide elastic members 235 is compressed, the movable mounting member 232 and the charging connector 22 swing upward, and when the lower group of main guide elastic members 235 is compressed, the movable mounting member 232 and the charging connector 22 swing downward, that is, the movable mounting member 232 and the charging connector 22 can swing in the up and down directions. Figure 12 , β is the angle at which the movable mounting member 232 and the charging connector 22 swing up and down.

[0049] Further, continue to refer to Figure 4 and Figure 5 as well as Figure 8 and Figure 9 The movable mounting member 232 is provided with four main guide posts 236. The ends of the main guide posts 236 facing away from the movable mounting member 232 are free ends. The four main guide posts 236 correspond one-to-one with the four main guide elastic members 235, and the main guide elastic members 235 are partially sleeved on the main guide posts 236. The main guide posts 236 are used to support and guide the main guide elastic members 235. Furthermore, the fixed mounting member 231 is provided with four positioning slots 2311, which correspond one-to-one with the four main guide elastic members 235. The ends of the main guide elastic members 235 facing away from the movable mounting member 232 are located within the positioning slots 2311, thereby facilitating the positioning and installation of the main guide elastic members 235.

[0050] The main guide assembly also includes two balancing elastic members 237, which are located on either side of the fixed mounting member 231 and the movable mounting member 232 along the left and right directions of the charging device. The fixed mounting member 231 is provided with a hanging column 2312, and the movable mounting member 232 is provided with a hanging hole 2322. One end of the balancing elastic member 237 is connected to the hanging column 2312 on the fixed mounting member 231, and the other end is connected to the hanging hole 2322 on the movable mounting member 232. The two balancing elastic members 237 are both inclined, and the ends of the two balancing elastic members 237 connected to the fixed mounting member 231 are inclined in a direction away from each other. The balancing elastic members 237 are used to assist the hanging elastic member 233 and the main guide elastic member 235 in resetting after the movable mounting member 232 and the charging connector 22 move.

[0051] The main guide assembly in this embodiment is formed by a combination of elastic parts, which has a simple structure and low cost.

[0052] In addition, the docking mechanism 20 also includes a front guide assembly 21, which includes a first front mounting member 211, a second front mounting member 212, a front guide post 213, and a front guide elastic member 214. The first front mounting member 211 and the second front mounting member 212 are spaced apart along the front-to-back direction of the charging device. The first front mounting member 211 is mounted on the movable mounting member 232, and the charging connector 22 is mounted on the second front mounting member 212. One end of the front guide post 213 is connected to one of the first and second front mounting members 211, 212, and the other end passes through the other and slidably engages with the other. The front guide elastic member 214 is sleeved on the portion of the front guide post 213 located between the first and second front mounting members 211, 212. Under the guidance of the front guide assembly 21, the charging connector 22 can move in the front-to-back direction.

[0053] Optionally, there are four front guide posts 213 and four front guide elastic members 214, each corresponding to the other. The four front guide posts 213 and the four front guide elastic members 214 are arranged in a 2*2 matrix, thereby making the guiding movement of the charging connector 22 by the front guide assembly 21 more stable. However, the number and arrangement of the front guide posts 213 and the front guide elastic members 214 are not limited to this.

[0054] When the charging connector 22 is docked with the mobile robot, the charging connector 22 will first move in the front-to-back direction under the guidance of the front guide component 21, and then move in the front-to-back direction and / or swing in the left-to-right direction and / or swing in the up-down direction under the guidance of the main guide component. That is, the front guide component 21 first performs primary guidance on the charging connector 22, and then the main guide component performs secondary guidance on the charging connector 22, so that the charging connector 22 can be accurately docked with the mobile robot.
