Detailed Implementation

[0029] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] In the first aspect, this application provides a battery swapping device. One end of the battery swapping device is provided with a locking structure that can cooperate with a lock in the charging compartment. When the battery swapping device needs to be charged, it is placed in the charging compartment. The locking structure on the battery swapping device can cooperate with the lock, thereby reducing the risk of the battery swapping device being stolen.

[0032] like Figure 1 , 5 As shown in Figure 7, the battery swapping device includes a power supply component and a battery casing. The battery casing includes a casing body 1, which is used to house the power supply component. One end of the casing body 1 has two spaced grooves 11. One end of the casing body 1 also has a locking member 2. The two ends of the locking member 2 in the length direction can extend to cover part of the opening area of ​​the two grooves 11. In this way, the remaining part of the opening of the groove 11 is used for the latch 4 to pass through. When the battery swapping device needs to be placed in the charging compartment for charging, the latch 4 in the charging compartment can pass through the remaining part of the opening of the groove 11 and lock onto the edge position of both ends of the locking member 2, thereby realizing the mutual locking between the battery swapping device and the lock and reducing the risk of the battery swapping device being stolen.

[0033] Optionally, the locking element 2 can be elongated, with both ends along its length covering the partial openings of the two grooves 11.

[0034] Optionally, the shell body 1 can be a plastic part, including an upper shell and a base, and the groove 11 can be set on the base, with the upper shell and the base interlocking with each other.

[0035] Optionally, in this embodiment, the structure of the lock is not specifically limited; any lock that can be engaged and locked with the two ends of the locking member 2 is acceptable.

[0036] Optionally, when the latch 4 is engaged with both ends of the locking element 2, the battery cannot be removed from the charging compartment and must be unlocked via mobile phone or remote control.

[0037] Optionally, the locking element 2 is a sheet metal part, thereby improving the structural strength of the locking element 2.

[0038] like Figure 2 and 5 As shown, in one embodiment, the locking member 2 is provided with a plurality of protrusions 21 on the side facing the groove 11. The protrusions 21 are located at the edge position of the locking member 2 for engaging with the latch 4, which can increase the contact area with the latch 4 and improve the stability between the latch 4 and the locking member 2.

[0039] Optionally, the locking member 2 is provided with two protrusions 21, each protrusion 21 being located at both ends in the length direction, thereby increasing the contact area with the latch 4.

[0040] Optionally, the protrusion 21 can be a triangular prism structure or a cylindrical structure.

[0041] like Figure 3 As shown, in one embodiment, the end of the shell body 1 is also provided with a receiving groove 12 for accommodating the locking member 2. The depth of the receiving groove 12 is the same as the thickness of the locking member 2. In this way, when the locking member 2 is installed in the receiving groove 12, the locking member 2 can be flush with the end face of the shell body 1, which improves the aesthetics of the battery swapping device.

[0042] Optionally, a notch is provided at one of the top corners of the locking member 2, the shape of the positioning groove 14 is adapted to the shape of the locking member 2, and the notch can be adapted to the protrusion 21. During the assembly process of the shell body 1 and the locking member 2, the assembly efficiency can be improved.

[0043] like Figure 3 and 5 As shown, in one embodiment, the locking member 2 is provided with multiple guide holes 22, and one end of the shell body 1 is provided with multiple guide spaces 13. The guide holes 22 are connected to the guide spaces 13 for the positioning pins 3 of the lock to pass through, thereby realizing the positioning between the battery and the lock, improving the stability between the two, and also enabling the charging connector 5 to connect with the connector 7 in the charging compartment.

[0044] Optionally, there are two guide holes 22, each of which is coaxial with the corresponding guide space 13. In this way, when the battery is placed in the charging compartment, the positioning pin 3 on the lock can be inserted into the guide space 13 through the guide hole 22.

[0045] like Figure 4 As shown, in one embodiment, the battery casing also includes a charging connector 5, which includes a connector body and a flange 51 connected to the connector body. One end of the casing body 1 is provided with a positioning groove 14 that matches the shape of the flange 51. The bottom wall of the positioning groove 14 is also provided with a first through hole 15 through which the connector body can pass. When the charging connector 5 is connected to the casing body 1, the flange 51 can be placed in the positioning groove 14 to position the charging connector 5. The connector body passes through the first through hole 15 and is electrically connected to the power supply component inside the casing body 1.

[0046] Optionally, the positioning groove 14 extends downward along the bottom wall of the receiving groove 12.

[0047] Optionally, the charging connector 5 can be connected to the positioning slot 14 with a screw.

[0048] like Figure 3 and 4 As shown, in one embodiment, the bottom wall of the positioning groove 14 is provided with at least two positioning parts 141, and the flange 51 is provided with positioning holes 23 corresponding to the positioning parts 141, thereby further improving the stability between the charging connector 5 and the positioning groove 14.

[0049] Optionally, the positioning part 141 is a protruding column structure with a protrusion 21 along the bottom of the positioning groove 14.

[0050] Optionally, four positioning units 141 can be provided.

[0051] like Figure 3 As shown, in one embodiment, the locking member 2 is provided with a second through hole 24, and the connector body includes a charging end 52 protruding along the flange 51. The charging end 52 is embedded in the second through hole 24. In this way, the locking member 2 presses the charging connector 5 together, and the locking member 2 fits against the flange 51, restricting the charging connector 5 in the positioning groove 14, reducing the problem of the charging connector 5 falling off. Moreover, the locking member 2 can cooperate with the positioning part 141 to achieve the positioning function of the charging connector 5, thereby eliminating the need for the charging connector 5 to be connected to the shell body 1 by screws. On the one hand, this improves assembly efficiency and reduces assembly steps; on the other hand, it also reduces the error between the charging connector 5 and the connector 7 in the charging compartment, which can improve the accuracy of docking. If the charging connector 5 is connected to the shell body 1 by screws, the screw's turning process will cause the flange 51 to shift to a certain extent, which will result in the charging connector 5 not being able to be coaxially inserted with the connector 7 in the charging compartment.

[0052] Optionally, the second through hole 24 is located at the center of the locking member 2.

[0053] Optionally, the distance from the end of the charging terminal 52 to the flange 51 is the same as the thickness of the locking member 2, so that when the charging terminal 52 is embedded in the second through hole 24, it can be flush with the locking member 2.

[0054] As one implementation, the battery casing is also provided with a battery presence detection device for cooperating with the lock. The battery presence detection device is connected to the casing body 1. By setting the battery presence detection device, it is possible to prevent the battery from being falsely locked and reduce the risk of the battery being stolen.

[0055] like Figures 3 to 5 As shown in Figure 9, optionally, the lock includes a reed switch assembly 18, and the battery presence detection device includes a magnet 6. The magnet 6 is located at one end of the housing body 1. When the battery is placed in the charging compartment, the reed switch assembly 18 cooperates with the magnet 6 to detect that the battery is in place, and then the latch 4 locks the locking member 2 to reduce the possibility of the battery being stolen due to a false lock.

[0056] Optionally, the battery presence detection device can also be a protrusion on the housing body 1, and the lock can include an elastic protrusion 21. When the battery is placed in the charging compartment, the protrusion can compress the elastic protrusion 21, so that the lock detects that the battery is in place, and then locks the locking member 2 through the latch 4.

[0057] like Figures 3 to 5 As shown, in one embodiment, the battery presence detection device includes a magnet 6 and a locking element 2 which is a non-magnetic element. When the battery presence detection device is a magnet 6, the locking element 2 is set to a non-magnetic element, thereby reducing the interference of the reed switch assembly 18 on the detection of the magnet 6.

[0058] Optionally, the power supply component can be a lithium battery or a lead-acid battery.

[0059] like Figure 5 , 6 As shown in Figures 9 and 10, in a second aspect, embodiments of this application provide a battery swapping cabinet, including a cabinet body. The cabinet body is provided with multiple charging compartments for charging swapping batteries. Each charging compartment is provided with a lock, which includes a latch 4. The swapping battery with charging locking function provided in the first aspect can be placed into the charging compartment, and the latch 4 can lock the swapping battery, thereby reducing the risk of the swapping battery being stolen.

[0060] Optionally, the locks in this application embodiment can also be applied to charging cabinets.

[0061] like Figure 6 , 9 As shown in Figure 10, optionally, the lock also includes a positioning pin 3, which can position and guide the battery swapping device so that the charging connector 5 can be inserted and engaged with the connector 7 in the charging compartment, thereby enabling the charging compartment to charge the battery swapping device.

[0062] like Figure 5 and 9 As shown, optionally, the lock also includes a reed switch assembly 18, which cooperates with the magnet 6 on the battery swapping device to detect the presence of the battery swapping device; as shown Figure 6 , 8 As shown in Figure 9, the lock also includes a motor 9, with a motor gear on the shaft of the motor 9. The lock also includes a reduction gear 10, which meshes with the motor gear, as shown in Figure 9. Figure 6 and 9 As shown, the lock also includes an eccentric wheel 16 and a push rod 8 connected to the eccentric wheel 16. The eccentric wheel 16 meshes with the reduction gear 10. The eccentric wheel 16 includes an eccentric column 161. The push rod 8 is connected to the latch 4 and is provided with a guide rail, such as... Figure 6 and 7 As shown, when the motor 9 receives the unlocking command, it starts to rotate, driving the motor 9 to rotate the motor gear, which in turn drives the reduction gear 10 to rotate, thereby driving the eccentric wheel 16 to rotate. The eccentric column 161 on the eccentric wheel 16 contacts the guide rail on the push rod 8, causing the push rod 8 to move toward the battery swapping direction, and the latch 4 opens.

[0063] like Figure 8 and 9As shown, the lock also includes a micro switch 17, which is used to detect the rotation angle of the eccentric wheel 16 to control the locking and unlocking of the lock. A protrusion 162 is provided in a portion of the circumference of the eccentric wheel 16. When the protrusion 162 on the eccentric wheel 16 contacts the micro switch 17, the motor 9 receives a command and stops rotating, the latch 4 stops in the unlocked position, and the lock is unlocked.

[0064] like Figure 6 and 7 As shown, after the battery is removed, the reed switch assembly 18 detects that the battery has been removed, and the motor 9 receives the command to start rotating. The drive motor 9 drives the motor gear to rotate, and the rotation of the motor gear drives the reduction gear 10 to rotate, thereby driving the eccentric wheel 16 to rotate. The eccentric column 161 on the eccentric wheel 16 contacts the guide rail on the push rod 8, causing the push rod 8 to move away from the positioning pin 3. The torsion spring 19 resets the latch 4. When the boss 162 on the eccentric wheel 16 disengages from the micro switch 17, the motor 9 receives the command to stop rotating, and the latch 4 will stop in the locked position.

[0065] When the battery is locked, the battery is pushed into the charging compartment along the charging compartment guide rail. The positioning pin 3 on the lock will guide the battery to the appropriate position. When the battery contacts the latch 4, the locking member 2 will open the latch 4 through the guide angle of the latch 4. After the battery passes the chamfer of the latch 4, the latch 4 will return to the locked state under the action of the torsion spring 19. The latch 4 will lock the battery, thus locking the battery. The reed switch assembly 18 detects whether the battery is in place, thereby determining whether the battery is fully locked, reducing the risk of the battery being stolen.

[0066] Optionally, this application only describes the structure of one type of lock in the embodiments. Of course, other locks that can be adapted to the battery swapping system can also be installed in the cabinet.

[0067] Optionally, in this embodiment, the operation of closing the compartment door after inserting the battery is eliminated, making the operation more convenient and efficient.
