[0049] Figures 1 to 3 A charging plug-in device 120 for a battery pack 100 according to the present invention is shown. The charging plug-in device 120 is used in a charging and swapping system. The charging and swapping system includes a conveying device for transferring the battery pack 100 along the horizontal and vertical Z directions of the charging plug-in device 120. The charging plug-in device 120 includes a fixing plate 130, a mounting base 140, an electrical plug 160, an elastic member 170, and a transmission member 180.

[0050] Mounting base 140 is movably connected to mounting plate 130 along a first horizontal direction D1 between a plugged-in position and a disengaged position. Electrical plug 160 is disposed on mounting base 140. Mounting base 140 is closer to battery pack 100 in the plugged-in position compared to the disengaged position.

[0051] The two ends of the elastic member 170 are connected to the fixed plate 130 and the mounting base 140, respectively. The elastic member 170 is configured to apply an elastic force toward the insertion position to the mounting base 140. The transmission member 180 is disposed on the mounting base 140 and protrudes from the mounting base 140 along the first horizontal direction D1 toward the insertion position. The transmission member 180 is used to abut against the transport equipment and push the mounting base 140 to the disengagement position when the transport equipment approaches the charging plug-in device 120.

[0052] According to the charging plug-in / plugging device 120 of the battery pack 100 of this utility model, through the cooperation of the transmission component 180 and the transport equipment of the battery pack 100 and the action of the elastic component 170, the mounting base 140 is moved between the plugging position and the disengaging position, thereby realizing the plug-in / plugging action of the plug 160 and the battery pack 100. No additional drive source or complex circuit control is required to complete the charging plug-in / plugging operation. The control is simple, the control accuracy requirement is low, the control difficulty is low, and the manufacturing cost of the charging plug-in / plugging device 120 is reduced.

[0053] According to the present invention, a charging plug-in device 120 for a battery pack 100 is used to cooperate with a transport device for the battery pack 100 to realize the charging plug-in operation of the battery pack 100. In particular, the transport device can transfer the battery pack 100 along the horizontal and vertical directions Z of the charging plug-in device 120.

[0054] Furthermore, this utility model also provides a charging and swapping system, including a charging and plugging device 120 for the battery pack 100 as described above, and a transport device. The transport device includes a vehicle body and a supporting mechanism. The supporting mechanism is disposed on the vehicle body and is used to carry the battery pack 100 and transfer the battery pack 100 along the height direction Z of the charging and plugging device 120. The vehicle body is used to move along the horizontal direction of the charging and plugging device 120. According to the charging and swapping system of this utility model, no additional drive source or complex circuit control is required to complete the charging and plugging operation of the battery pack 100. The control is simple, the control accuracy requirement is low, the control difficulty is small, and the manufacturing cost is reduced.

[0055] In some specific embodiments of this utility model, refer to Figure 1 and Figure 2 The handling equipment may include an AGV (Automated Guided Vehicle), which includes a carrying mechanism, which may be the AGV's fork mechanism, enabling the battery pack 100 to move along the horizontal and vertical Z directions of the charging and plugging device 120. The charging and swapping system also includes a push block 110, which is disposed on the carrying mechanism and is used to abut against the transmission member 180, so that the movement of the carrying mechanism can drive the mounting base 140 to move through the transmission member 180, thereby realizing the charging and plugging operation of the battery pack 100 with the cooperation of the elastic member 170.

[0056] In some specific embodiments of this utility model, refer to Figure 2 The charging plug-in / plugging device 120 also includes a guide mechanism 150, which includes a slider 151 and a guide rail 152. The guide rail 152 is disposed on the fixing plate 130 and extends along a first horizontal direction D1. The slider 151 is connected to the bottom of the mounting base 140, and the slider 151 is movably engaged with the guide rail 152 along the first horizontal direction D1, thereby allowing the mounting base 140 to be movably connected to the fixing plate 130 along the first horizontal direction D1. The arrangement of the guide mechanism 150 makes the movement direction of the mounting base 140 relative to the fixing plate 130 more stable, which helps to improve the plug-in / plugging accuracy between the plug 160 and the battery pack 100.

[0057] In some specific embodiments of this utility model, refer to Figure 2 and Figure 3 The charging plug-in / plug-out device 120 includes two guide mechanisms 150. The two guide mechanisms 150 are arranged at both ends of the mounting base 140 along a second horizontal direction D2 perpendicular to the first horizontal direction D1, so that the support force at both ends of the mounting base 140 is more balanced, which helps to prevent the mounting base 140 from tilting and further improves the plug-in / plug-out accuracy between the plug 160 and the battery pack 100.

[0058] In some specific embodiments of this utility model, refer to Figure 2 The fixing plate 130 is provided with a mounting groove 131, which is located on the top surface of the fixing plate 130 and extends along the first horizontal direction D1. The guide rail 152 is partially embedded in the top surface of the fixing plate 130 through the mounting groove 131, and the guide rail 152 is connected to the fixing plate 130 by fasteners 144, thereby providing a positioning effect for the installation of the guide rail 152. In addition, the mounting groove 131 also has a limiting effect on the guide rail 152, preventing the guide rail 152 from deflecting, and further improving the insertion and removal accuracy between the plug 160 and the interface 101 of the battery pack 100.

[0059] In some specific embodiments of this utility model, refer to Figure 2 The mounting base 140 includes a connecting plate 141 and two support plates 142. The connecting plate 141 extends along a second horizontal direction D2. Two guide mechanisms 150 are arranged at both ends of the connecting plate 141 along the second horizontal direction D2, and the sliders 151 of the two guide mechanisms 150 are respectively connected to the bottom surfaces of both ends of the connecting plate 141. The two support plates 142 are respectively connected to both ends of the connecting plate 141 along the second horizontal direction D2, and the support plates 142 are connected to the ends of the electrical plug 160 by fasteners 144. The arrangement of the connecting plate 141 allows the mounting base 140 to have a certain span along the second horizontal direction D2, and, in conjunction with the guide mechanisms 150 at both ends of the mounting base 140, makes the movement of the mounting base 140 more stable. The arrangement of the support plates 142, connecting the electrical plug 160 at both ends of the connecting plate 141, makes the electrical plug 160 less prone to swaying, which helps to ensure the accuracy of the insertion and removal operation between the electrical plug 160 and the battery pack 100.

[0060] In some specific embodiments of this utility model, refer to Figure 2 The transmission component 180 includes a connecting block 181 and an adjusting bolt 182. The connecting block 181 is connected to the mounting base 140, and an adjusting hole 183 is provided on the side wall of the connecting block 181 near the battery pack 100. The adjusting bolt 182 passes through the adjusting hole 183 along the first horizontal direction D1 and is threadedly connected to the connecting block 181. The end of the adjusting bolt 182 is used to abut against the bearing mechanism of the conveying equipment.

[0061] Under the action of the elastic member 170, the mounting base 140 is in the plugged position when it is not subjected to external force. When the handling equipment moves the battery pack 100, the carrying mechanism of the handling equipment carries the battery pack 100, so that the battery pack 100 is transferred to the charging plug-in device 120 with the handling equipment. Then the carrying mechanism moves along the first horizontal direction D1 toward the direction close to the plug 160, so that the carrying mechanism abuts against the head of the adjusting bolt 182, thereby driving the mounting base 140 to move along the first horizontal direction D1 to the disengaged position through the connecting block 181. At this time, since the head of the adjusting bolt 182 protrudes from the mounting base 140, there is still a certain gap between the interface 101 of the plug 160 and the battery pack 100. Then the carrying mechanism of the transport equipment moves down along the height direction Z, so that the battery pack 100 is placed in the specified position. At the same time, the carrying mechanism moves down until it disengages from the head of the adjusting bolt 182. Under the elastic force of the elastic member 170, the mounting base 140 moves toward the insertion position until the electrical plug 160 on the mounting base 140 is inserted into the interface 101 of the battery pack 100, realizing the insertion and removal operation of the battery pack 100. No additional drive source is needed to perform the insertion and removal operation of the electrical plug 160. The control is simple, the control accuracy requirement is low, the control difficulty is low, and the manufacturing cost of the charging insertion and removal device 120 is reduced.

[0062] Furthermore, by rotating the adjusting bolt 182, the distance by which the adjusting bolt 182 protrudes from the mounting base 140 can be adjusted, thereby adjusting the disengagement position of the mounting base 140 and adjusting the amount of extension and retraction of the elastic member 170 when the bearing mechanism is disengaged from the adjusting bolt 182. This facilitates the adjustment of the force when the plug 160 and the battery pack 100 interface 101 are plugged in, which helps to reduce damage when the plug 160 and the battery pack 100 are plugged in, and also helps to prevent the plug 160 and the battery pack 100 from being loosely plugged in.

[0063] In some specific embodiments of this utility model, refer to Figure 2 and Figure 3 The elastic member 170 is constructed as a nitrogen spring. Both ends of the elastic member 170 are rotatably connected to the mounting base 140 and the fixing plate 130, respectively. This provides elastic force to the mounting base 140, which is offset from the insertion position, so that the mounting base 140 can move to the insertion position and be inserted into the interface 101 of the battery pack 100 when it is not subjected to external force.

[0064] In addition, a connecting portion 143 is provided on the side of the connecting plate 141 of the mounting base 140 near the battery pack 100 along the first horizontal direction D1. One end of the elastic member 170 is rotatably connected to the connecting portion 143 by a fastener 144, and the second end of the elastic member 170 is rotatably connected to the top surface of the fixing plate 130 by a fastener 144. This allows the elastic member 170 to be connected to the mounting base 140 and the fixing plate 130 respectively, which facilitates installation and reduces manufacturing costs.

[0065] In some specific embodiments of this utility model, refer to Figure 2 and Figure 3 The elastic member 170 forms an angle with the first horizontal direction D1. One end of the elastic member 170 near the insertion position is connected to the mounting base 140, and the other end near the disengagement position is connected to the fixing plate 130. By configuring the elastic member 170, the angle between the elastic member 170 and the first horizontal direction D1 gradually decreases as the mounting base 140 moves from the disengagement position to the insertion position. Therefore, during the process of the mounting base 140 moving from the disengagement position to the insertion position, the elastic force transmitted from the elastic member 170 to the mounting base 140 is more constant. This facilitates the adjustment and control of the elastic force on the mounting base 140, thereby reducing damage during the insertion of the plug 160 and the battery pack 100, and preventing the plug 160 and the battery pack 100 from being loosely connected.

[0066] This invention also provides a battery swapping station, including the charging and swapping system described above. The battery swapping station of this invention eliminates the need for an additional drive source and complex circuit control to complete the charging and plugging / unplugging operations of the battery pack 100. It features simple control, low precision requirements, low control difficulty, and reduced manufacturing costs.
