[0043] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0044] Please refer to Figure 1 , the embodiments of the present application provide a charging device 100, and the charging device 100 is used to charge a device to be charged. The device to be charged can be a robot, a driverless vehicle, a toy car, etc., specifically, it can be a delivery robot, a food delivery robot, a transportation robot, etc.

[0045] In some embodiments, please refer to Figure 2 and Figure 3 , the charging device 100 includes a housing 1, a fixing frame 2, a sliding frame 3, an electrode 4, and a driving component 5. The fixing frame 2 and the driving component 5 are arranged in the housing 1. The sliding frame 3 is slidably arranged on the fixing frame 2, and the electrode 4 is arranged on the sliding frame 3. The driving component 5 is arranged on the fixing frame 2. The driving component 5 is in transmission connection with the sliding frame 3, and the driving component 5 is used to drive the sliding frame 3 to slide relative to the fixing frame 2 along the first direction X. Among them, the electrode 4 is electrically connected to a power source, such as a secondary battery or a power grid, to charge the device to be charged when electrically connected to the device to be charged.

[0046] For the above-mentioned housing 1, please refer toFigure 2 and Figure 3 Inside the housing 1, a receiving cavity 11 is provided. An avoidance hole 12 is provided in the housing 1, and the avoidance hole 12 communicates the receiving cavity 11 with the outside of the housing 1. Among them, when the driving assembly 5 drives the sliding bracket 3 to slide relative to the fixed bracket 2 along the first direction X, the sliding bracket 3 drives the electrode 4 to at least partially extend out of the housing 1 from the avoidance hole 12, or drives the electrode 4 to retract from the avoidance hole 12 into the receiving cavity 11.

[0047] In the above manner, when the charging device 100 needs to charge the device to be charged, the driving assembly 5 can drive the electrode 4 to at least partially extend out of the housing 1 from the avoidance hole 12 to charge the device to be charged. When the charging device 100 does not need to charge the device to be charged, the driving assembly 5 can drive the electrode 4 to retract from the avoidance hole 12 into the receiving cavity 11, reducing the time that the electrode 4 is exposed outside the housing 1 and improving the problems of corrosion and damage of the electrode 4 and potential safety hazards.

[0048] In some embodiments, the avoidance hole 12 is adapted to the electrode 4. Exemplarily, please refer to Figures 2 to 4 , the electrode 4 includes a protruding portion 41.

When observed along the first direction X, the shape and size of the protruding portion 41 are the same as those of the avoidance hole 12, and the projection of the protruding portion 41 coincides with the projection of the avoidance hole 12, that is, the protruding portion 41 can just extend out of the avoidance hole 12. Among them, when observed along the first direction X, the size of the avoidance hole 12 can be slightly larger than the size of the protruding portion 41. For example, there is a gap between the inner wall of the avoidance hole 12 and the protruding portion 41, and the width of the gap is 0.5 to 2 mm, so that the protruding portion 41 can move more smoothly in the avoidance hole 12.

[0049] In some embodiments, the number of both the avoidance holes 12 and the electrodes 4 is multiple. Each electrode 4 corresponds to extending out of the housing 1 from one avoidance hole 12 or retracting from the avoidance hole 12 into the receiving cavity 11.

[0050] In some embodiments, please refer to Figure 2 and Figure 3 , the housing 1 includes a first housing 13 and a second housing 14. Both the first housing 13 and the second housing 14 are concave shell-shaped. The first housing 13 and the second housing 14 are covered and surrounded to form the receiving cavity 11. The first housing 13 and the second housing 14 can be detachably connected by screws, which is convenient for assembly or disassembly. It can be understood that one of the first housing 13 and the second housing 14 can be concave shell-shaped and the other can be flat plate-shaped. At this time, the first housing 13 and the second housing 14 can still be covered and surrounded to form the receiving cavity 11.

[0051] In some embodiments, referring to Figure 2 , the avoidance hole 12 is provided in the first housing 13. Wherein, the fixing frame 2 and the driving assembly 5 are both provided in the first housing 13, so that the second housing 14 does not affect the disassembly and assembly of the fixing frame 2, the sliding frame 3, the electrode 4 and the driving assembly 5, facilitating the assembly or disassembly of the fixing frame 2, the sliding frame 3, the electrode 4 and the driving assembly 5 in the accommodating cavity 11.

Optionally, the cross-section of the first sliding hole 31 is circular, and the cross-section of the first guiding column 21 is circular.

[0055] In some embodiments, referring to Figure 4 and Figure 5 , the number of both the first sliding holes 31 and the first guiding columns 21 is multiple, and each first guiding column 21 correspondingly passes through at least one first sliding hole 31, which is beneficial to increasing the sliding stability of the sliding frame 3 relative to the fixing frame 2.

[0056] The first guiding column 21 can be directly welded or adhesively connected to the housing 1, or can be indirectly connected to the housing 1.

Among them, when the first fixing plate 22 and the first guide column 21 are integrally formed, the first fixing plate 22 and the first guide column 21 can be made of plastic material, such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, etc., which not only has good insulation performance, but also is easy to be integrally formed.

[0058] In some embodiments, see Figure 4 and Figure 5 , the fixing frame 2 includes a second fixing plate 23, and the other end of the first guide column 21 is connected to the second fixing plate 23. That is, the two ends of the first guide column 21 are respectively connected to the first fixing plate 22 and the second fixing plate 23, which is conducive to reducing the bending or shaking of the first guide column 21 and increasing the stability of the sliding frame 3 relative to the fixing frame 2. Optionally, the second fixing plate 23 is detachably connected to the first guide column 21 by screws, which is convenient for assembly or disassembly.

[0059] In some embodiments, the second fixing plate 23 is connected to the housing 1.

In addition, the first guide column 21 is connected to the first fixing plate 22, so when viewed along the first direction X, the first guide column 21 surrounds the avoidance hole 12. That is, there are multiple positions where the sliding frame 3 is slidably connected to the fixing frame 2, and when viewed along the first direction X, the position where the sliding frame 3 is slidably connected to the fixing frame 2 surrounds the avoidance hole 12, which is beneficial to increase the stability of the electrode 4 extending from the avoidance hole 12 to the shell 1 or retracting from the avoidance hole 12 to the accommodating cavity 11, thereby improving the working reliability of the charging device 100.

That is, the first sliding plate 32 is slidably disposed on the first guide post 21. Wherein, the first sliding plate 32 is in transmission connection with the driving assembly 5, and the electrode 4 is disposed on the first sliding plate 32. By driving the first sliding plate 32 to slide along the first guide post 21 by the driving assembly 5, the electrode 4 can be driven to move along the first direction X, so that the electrode 4 can extend out of the housing 1 from the avoidance hole 12, or retract from the avoidance hole 12 into the accommodation cavity 11.

One end of the elastic member 34 is connected to the first sliding plate 32, and the other end of the elastic member 34 is connected to the electrode 4. When the electrode 4 is subjected to an external force, such as being squeezed by the device to be charged, the elastic member 34 can be deformed, such as being stretched or compressed, so that the electrode 4 moves along the second guide post 33, improving the problem that the device to be charged or the electrode 4 is damaged due to excessive pressure between the electrode 4 and the device to be charged. When the driving assembly 5 is working, it can also improve the problem that the driving assembly 5 is damaged due to suddenly receiving a huge resistance. Optionally, the elastic member 34 is a straight spring or a tension spring.

That is, both ends of the second guiding column 33 are respectively connected to the first sliding plate 32 and the second sliding plate 35, which is beneficial to reducing the bending or shaking of the second guiding column 33 and increasing the stability of the sliding of the electrode 4 relative to the sliding carriage 3. In this embodiment, the elastic member 34 can be supported between the second sliding plate 35 and the electrode 4.

[0066] In some embodiments, the second sliding plate 35 is fixedly connected to the second guiding column 33. For example, the second sliding plate 35 is connected to the second guiding column 33 by welding or bonding, or the second sliding plate 35 and the second guiding column 33 are integrally formed, which is beneficial to improving the connection strength between the second sliding plate 35 and the second guiding column 33, and also beneficial to reducing the assembly process of the second sliding plate 35 and the second guiding column 33 and improving the assembly efficiency. When the second sliding plate 35 and the second guiding column 33 are integrally formed, the second sliding plate 35 and the second guiding column 33 can be made of plastic materials such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, etc., which not only have good insulation performance but also are convenient for integral forming.

Moreover, since the second guiding column 33 is connected to the second sliding plate 35, when observed along the first direction X, the second guiding column 33 surrounds the avoidance hole 12. That is, there are multiple positions where the electrode 4 is slidably connected to the sliding carriage 3, and when observed along the first direction X, the positions where the electrode 4 is slidably connected to the sliding carriage 3 surround the avoidance hole 12, which is beneficial to making the resistance received by the electrode 4 uniform when the electrode 4 slides along the second guiding column 33 under an external force, and the electrode 4 is not prone to jamming during sliding on the sliding carriage 3 due to rotating around the axis perpendicular to the first direction X, thereby increasing the stability of the sliding of the electrode 4 along the sliding carriage 3.
