[0028] In some embodiments of the present disclosure, as shown in Figure 2 , the driving assembly 3 includes a transverse driving mechanism for moving the charging gun assembly 2 in the front-back direction and a longitudinal moving mechanism for moving the charging gun assembly 2 in the left-right direction. The transverse driving mechanism includes two sets of linear modules assembled in an up-down manner, and the two sets of linear modules control the movement of the charging gun assembly 2 to increase the movement distance of the charging gun assembly 2; the longitudinal moving mechanism includes a linear guide rail that moves the charging gun assembly 2 left and right under the action of external force to adjust the position, the linear guide rail is installed on the upper part of the transverse driving mechanism, and the charging gun assembly 2 is installed on the linear guide rail.

[0029] In some examples, as shown in Figure 1 and Figure 2As shown, the transverse driving mechanism comprises a first linear module 31 arranged on the inner bottom wall of the box body 1, a support plate 32 connected to the first linear module 31, a second linear module 33 mounted on the upper end of the support plate 32, the first linear module 31 and the second linear module 33 being the aforementioned linear modules, a fixed plate 34 connected to the slide of the second linear module 33, and a linear guide rail mounted on the fixed plate 34. Specifically, the linear guide rail comprises a guide rail plate 35 connected to the upper end of the fixed plate 34 and arranged vertically to the fixed plate 34, a linear guide rail 36 connected to the guide rail plate 35, and a first slider on the linear guide rail 36 to which the tail of the charging gun bracket 22 is fixed.

[0030] In some examples, the front end of the transverse driving mechanism is provided with an adjusting member for aligning the charging gun head 21 with the charging female head of the device to be charged. Specifically, the adjusting member comprises a blocking strip 321 connected to the front end of the support plate 32 and arranged vertically to the support plate 32, as shown in Figure 2 As shown, the driving assembly 3 pushes the charging gun head 21 outward, and when the charging female head is contacted, the blocking strip 321 adjusts the position of the charging female head first to make it align with the charging gun head 21, so that the charging gun head 21 can be inserted into the charging female head for charging when it continues to advance.

[0031] As another embodiment of the present case, the automatic charging alignment mechanism further comprises a centering assembly 4 for returning the charging gun assembly 2 to the central position of the transverse driving mechanism.

[0032] In some examples, referring to Figure 2 The centering assembly 4 comprises two centering baffles 41 symmetrically arranged on both sides of the charging gun assembly 2, which are slidingly installed on the linear guide rail. Specifically, the centering baffles 41 are fixed on the second sliders of the linear guide rail 36, and the two second sliders are symmetrically arranged on both sides of the first slider. The centering baffles 41 are hingedly connected to guide shafts 42, the other ends of which point to the transverse driving mechanism. The distance between the two centering baffles 41 is adjusted by the driving device to center the charging gun assembly 2. Specifically, the driving device is a third linear module 43 mounted on the fixed plate 34, and the two guide shafts 42 are hingedly connected to the sliders of the third linear module 43. The third linear module 43 pulls the two centering baffles 41 through the two guide shafts 42 to move in the same or opposite directions along the linear guide rail 36. When moving in the same direction, the centering effect is achieved, which can ensure that the charging gun head 21 is in the middle position after charging. When moving in the opposite direction, the moving distance of the charging gun head 21 on the linear guide rail 36 is increased, which expands the range of docking registration.

The guide rod 24 on the charging gun assembly 2 abuts against the rotating assembly of the device to be charged. Under the action of an external force, the charging gun assembly 2 moves on the linear guide rail 36 to accurately align the charging gun head 21 with the charging female head. At the same time, the third linear module 43 pushes the two guide shafts 42 to move forward, so that the distance between the two centering baffles 41 is enlarged, the moving distance of the charging gun assembly 2 on the linear guide rail 36 is enlarged, the position of the charging female head is adjusted by the blocking strip 321, so that the charging female head of the device to be charged is in a flush position with the charging gun head 21, and when the blocking strip 321 abuts against the rotating assembly of the device to be charged, the position of the charging female head is limited. Then the second linear module 33 pushes the linear guide rail 36 to continue to move outward, so that the charging gun head 21 is inserted with the charging female head of the device to be charged, the charging is completed, the guide rod 24 is inserted into the notch provided in the rotating assembly of the device to be charged, and the movement of the charging gun head 21 is not affected; after the charging is completed, the second linear module 33 drives the charging gun head 21 to separate from the charging female head and the guide rod 24 to separate from the rotating assembly of the device to be charged, the third linear module 43 drives the two guide shafts 42 to move back, and the two centering baffles 41 move towards each other to center the charging gun assembly 2.
