[0055] In the embodiment of the utility model, the charging needle assembly 2 includes a needle seat 21 and a charging needle 22, the needle seat 21 is made of plastic or other insulating materials, in order to accurately and smoothly contact the pile for charging, the front end of the charging needle 22 (i.e. the end away from the needle seat 21) is designed as a tapered spherical surface, one end of the charging needle 22 is fixedly arranged in one end of the needle seat 21, the end of the needle seat 21 away from the charging needle 22 is rotatably arranged in the rotating groove 11, the torsional spring 5 is connected with the needle seat 21, facilitating the setting of the charging needle assembly 2.

[0056] As Figure 5As shown, the needle holder 21 is provided with a rotating hole 23 that passes through both ends of the top and bottom of the needle holder 21. The rotating shaft 12 passes through the rotating hole 23. The side wall of the needle holder 21 away from the charging needle 22 is provided with a receiving groove 24.

Then, the limiting screw 16 is screwed into the limiting seat 15 at the top of the first mounting base 1, thereby limiting the top and bottom ends of the rotating shaft 12.

[0058] In a preferred embodiment of this utility model, a connecting rod 6 and a fixing screw 7 are further included. The two ends of the connecting rod 6 are rotatably connected to the two needle seats 21 respectively. Specifically, the bottom of each needle seat 21 is provided with a threaded hole 26, and both ends of the connecting rod 6 are provided with through holes 61. The two fixing screws 7 pass through the through holes 61 at both ends of the connecting rod 6 and are threadedly connected to the threaded holes 26.

[0059] In an embodiment of this utility model, the elastic charging slot assembly 4 includes an electrode plate 41, which forms a frame structure with openings at both ends spaced apart. A connecting piece 42 is provided in the middle of the electrode plate 41, and a connecting hole is provided on the connecting piece 42.

The guide part consists of two guide pieces 43 that are fixedly connected to both ends of the electrode plate 41. The guide pieces 43 and the electrode plate 41 are integrally fixedly connected. The distance between the two guide pieces 43 gradually increases from the end connected to the electrode plate 41 to the end away from the electrode plate 41.

[0060] More preferably, the second mounting base 3 is provided with a charging slot 31, the frame structure is disposed in the charging slot 31, and the opening of the frame structure faces the slot of the charging slot 31. The slot of the charging slot 31 is provided with a guiding arc surface 32 for guiding the charging pin assembly 2 to the guide plate 43. The guiding arc surface 32 is located in the extension direction of the guide plate 43 and can be an inclined surface or an arc surface.

[0061] The electrode plates 41 form a frame-like structure, which can be a circular frame, a quadrilateral frame, or a frame structure of other shapes. It is necessary to ensure that the inner circle of the frame structure is larger than the front end of the charging pin 22, so that the charging pin 22 can be inserted into the frame structure from a certain angle. Guide plates 43 are provided on both sides of the opening, enabling the charging pin assembly 2 to be accurately inserted into the frame structure from different angles and to abut against the electrode plates 41, ensuring the stability of the electrical connection. The guide plates 43 and the electrode plates 41 are integrally fixedly connected, resulting in a simple structure and convenient manufacturing. The guide arc surface 32 further improves adaptability. When the charging pin assembly 2 deflects significantly from the elastic charging slot assembly 4 and moves out of the guide plate's range, the guide arc surface 32 can guide the charging pin assembly 2 to the guide plate 43, thereby guiding it into the frame structure and achieving precise insertion and electrical connection.

[0062] When the custom torsion spring 5 is not subjected to any external force, the two charging pins 22 remain parallel, and the charging pins 22 and the first mounting base 1 remain naturally perpendicular. Figure 6 As shown. When the charging pin 22 is impacted by an external force, the torque of the torsion spring 5 causes the charging pin 22 to swing left and right at the same angle and in the same direction, as shown. Figure 7 As shown; after the charging pin 22 contacts the guide arc surface 32, it will smoothly enter and contact the guide plate 43 and the electrode plate 41, as shown. Figure 8 , Figure 9 As shown, after the spherical end face of the front end of the charging pin 22 contacts the guide plate 43, it will smoothly insert into the bottom of the electrode plate 41. Through the elastic opening structure of the electrode plate 41, the charging pin 22 and the electrode plate 41 can achieve three-point contact charging. As long as any one point contacts, the machine can be charged, ensuring the reliability of contact charging.
