[0054] Embodiment one
[0055] Reference Figures 1 to 9The utility model embodiment provides a kind of shared power bank locking device, for locking or unlocking power bank 100.The shared power bank locking device includes shell 1, lock hook component 2, locking component 3 and drive component 4, wherein, lock hook component 2, locking component 3 and drive component 4 are all installed on shell 1, lock hook component 2 directly cooperates with power bank 100, and drive component 4 is used to drive locking component 3 movement, realize the locking or unlocking of lock hook component 2 and power bank 100.
[0056] Specifically, shell 1 has guide rail 11, and lock hook component 2 is movably installed in guide rail 11;lock hook component 2 has first boss 21, second boss 22 and third boss 23;first boss 21 is used to abut against contact end face 101 of power bank 100, second boss 22 is at least partially inserted into lock hole 102 of power bank 100, the minimum distance between first boss 21 and second boss 22 is L1, the minimum distance between contact end face 101 and the end face of lock hole 102 is L2, L1 and L2 satisfy: L2=L1-A, A is a preset error, A≥0 mm;locking component 3 is movably installed on shell 1, locking component 3 includes limiting protrusion 31, and drive component 4 is used to drive limiting protrusion 31 to enter or exit the moving path of third boss 23, so as to realize the locking or unlocking of power bank 100.
[0057] Through the above scheme, by the reasonable setting of the minimum distance L1 between first boss 21 and second boss 22 and the minimum distance L2 between contact end face 101 and the end face of lock hole 102, the size of power bank 100 and lock hook component 2 can be matched, so that when first boss 21 abuts against and fits with contact end face 101 of power bank 100, at least part of second boss 22 can be inserted into lock hole 102 of power bank 100, thereby avoiding the error insertion and locking of non-matching power bank 100.In addition, lock hook component 2 is installed in guide rail 11 and can move along guide rail 11, when power bank 100 needs to be locked, first boss 21 abuts against contact end face 101 of power bank 100, second boss 22 extends into lock hole 102, and third boss 23 can abut against limiting protrusion 31 entering the moving path of third boss 23, thereby realizing the limiting locking of power bank 100;when power bank needs to be taken out, limiting protrusion 31 exits the moving path of third boss 23, so that lock hook component 2 can move along guide rail 11 again, and in this process, first boss 21 can push power bank 100 out.It is not difficult to understand that through the above scheme, lock hook component 2 can be used for matching with power bank 100 to prevent error insertion, and also can be used for pushing out power bank 100 for user to take, so that the structure design is more reasonable and compact, the input of parts can be reduced, and the installation difficulty, maintenance cost and manufacturing cost can be reduced.
[0058] It is worth mentioning that the "minimum distance between the first boss 21 and the second boss 22" is the distance L1 between the two parallel end faces of the first boss 21 and the second boss 22 arranged opposite to each other, and the "distance between the contact end face 101 and the end face of the lock hole 102" is the distance L2 between the innermost end face of the side of the power bank 100 provided with the contact and the end face of the lock hole 102 which is parallel to the innermost end face and closest to the innermost end face. Among them, "the preset error A=0mm" means that when the first boss 21 abuts and fits with the contact end face 101 of the power bank 100, the end face of the second boss 22 towards the first boss 21 abuts and fits with the end face of the lock hole 102 which is parallel to the contact end face 101 and closest to the contact end face 101. At this time, it can not only prevent the power bank from being inserted incorrectly, but also limit the power bank 100 between the first boss 21 and the second boss 22, so that the power bank 100 is more stable during insertion. If A>0mm, it means that the second boss 22 can be inserted into the lock hole 102, but there is a certain error between L1 and L2 (see Figure 9 ); and it should be understood that even with this preset error, the power bank 100 adapted to the product can still be distinguished from power banks of other brands, and A is a value that can be set according to actual conditions.
[0059] Referring to Figures 1 to 6 , in order to facilitate the locking hook assembly 2 to clamp the power bank 100 in the locked state of the power bank 100, and at the same time, in the unlocked state, the second boss 22 of the locking hook assembly 2 does not limit the first boss 21 to push the power bank 100 out, in the embodiment, the guide rail 11 has a retracted accommodation area 111 and a vertical guide area 112; along the insertion direction of the power bank 100 (i.e. the X1 direction as shown in Figure 3 ), the retracted accommodation area 111 and the vertical guide area 112 are distributed in sequence; the locking hook assembly 2 further comprises a guide column 24 movably installed in the vertical guide area 112.
[0060] It can be understood that the inner accommodation area 111 is formed by two straight plates 1111 which are perpendicular to the inner side end face of the shell 1, and the two straight plates 1111 are inclined away from the power bank 100 at the side close to the insertion end of the power bank 100, so that when the hook assembly 2 moves to the inner accommodation area 111, the second boss 22 can be retracted into the shell 1, without affecting the ejection of the power bank 100. The vertical guide area 112 can be provided as a straight slot on the shell 1, for guiding the hook assembly 2 to move in a preset direction, so that the second boss 22 can extend into the lock hole 102 to achieve the locking of the power bank 100. It should be noted that as a preferred, the guide column 24 is provided as a cylindrical rod, so that the guide column 24 can move along the straight slot and can also rotate in the straight slot. Of course, in other embodiments, the vertical guide area 112 can be provided as a guide rail, so that the guide column 24 can rotate during sliding in the guide rail (rotation is limited by the side wall of the guide rail), and at this time, the guide rail can be set according to the preset running path of the guide column 24.
[0061] In order to enable the first boss 21 of the hook assembly 2 to directly eject the power bank 100 when it is not limited by the limiting protrusion 31, in the embodiment, the shared power bank locking device further comprises a hook 5 and a first elastic member 6, wherein the hook 5 is fixedly arranged on the shell 1 and located at the side of the inner accommodation area 111 away from the vertical guide area 112; one end of the first elastic member 6 is connected with the guide column 24, and the other end is connected with the hook 5, and the first elastic member 6 has a tendency to drive the hook assembly 2 to reset to the inner accommodation area 111.
[0062] Further, the first elastic member 6 comprises a spring body 61 and a ring-shaped sleeve 62, and both ends of the spring body 61 are provided with a ring-shaped sleeve 62, one of which is sleeved on the hook 5, and the other is sleeved on the guide column 24. The spring body 61 is always in a stretched state, so as to have a tendency to drive the hook assembly 2 to reset to the inner accommodation area 111. Of course, in other embodiments, the spring body 61 can be in a free state when the hook assembly 2 is located in the inner accommodation area 111.
[0063] It can be understood that after the power bank 100 is unlocked and ejected, the first boss 21 at least partially protrudes from the side wall of the shell 1, so that when the power bank 100 is inserted, the first boss 21 can be pushed, thereby pushing the entire hook assembly 2 to move and realize locking cooperation with the power bank 100, and at the same time, the first elastic member 6 can be energized for the next time to eject the power bank 100. Of course, in other embodiments, the hook assembly 2 can also be directly driven by electricity (such as motor, electric push rod, etc.).
[0064] Referring to Figures 2 to 6The contact end face 101 of the power bank 100 is provided with a plurality of contacts; the first boss 21 is provided with a displacement area 211, and the displacement area 211 is opposite to the contacts when the first boss 21 abuts against the contact end face 101, so that the first boss 21 can extend a certain distance along the width direction of the power bank 100, so as to ensure that the first boss 21 has sufficient abutting area with the power bank 100, ensure the locking effect of the power bank 100, ensure that the first boss 21 can push out the power bank 100 and at least partially protrude from the side wall of the shell 1 when unlocking, and meanwhile, the power bank 100 can still be connected to electricity.
[0065] Referring to Figures 2 to 6 The second boss 22 has a circular arc surface 221 on the side facing the insertion end of the power bank 100, so that the second boss 22 can be better clamped into the lock hole 102.
[0066] Referring to Figures 2 to 6 The lock hook assembly 2 is symmetrically provided with two, which are respectively used for cooperating with two adjacent power banks 100 on the same plane, so that one shared power bank locking device can control the locking and unlocking of two power banks 100 at the same time. Correspondingly, the limiting protrusion 31 also includes a first limiting protrusion 311 and a second limiting protrusion 312, which are respectively matched with the two lock hook assemblies 2.

In addition, the first guide surface 3111, the second guide surface 3121 and the second elastic member 40 cooperate with each other, so that the locking assembly 3 will not affect the insertion of the power bank 100 (that is, during the process of inserting the power bank 100, the first limiting protrusion 311 and the second limiting protrusion 312 will not affect the movement of the corresponding lock hook assembly 2), and after the power bank 100 is pushed in, automatic locking can be realized.
[0068] In order to facilitate the installation of the second elastic member 40, the first moving block 32 is provided with a first protrusion 321, and the second moving block 33 is provided with a second protrusion 331; one end of the second elastic member 40 is sleeved on the first protrusion 321, and the other end is sleeved on the second protrusion 331. Specifically, the second elastic member 40 can be a spring, and the inner walls of both ends of the spring are respectively in abutment with the first protrusion 321 and the second protrusion 331.

[0071] In summary, the specific operation process of the shared power bank locking device is as follows (see Figures 1 to 9 )
[0072] When the power bank 100 is inserted, the power bank 100 is inserted along the X1 direction, and in this process, the power bank 100 pushes the first boss 21, thereby pushing the entire hook assembly 2 to move away from the retracted accommodation area 111, and at the same time, the hook assembly 2 swings around the central axis of the guide column 24 to move close to the power bank, so that the second boss 22 moves towards the power bank 100, and when the end face of the first boss 21 completely matches the contact end face 101, the second boss 22 is just clamped into the lock hole 102, and the third boss 23 abuts against the end face of the first limiting protrusion 311 (or the second limiting protrusion 312), thereby confirming that the power bank 100 is matched. Continue to push the power bank 100, so that the power bank 100 and the hook assembly 2 move synchronously along a straight line; in this process, the third boss 23 contacts the first guide surface 3111 (or the second guide surface 3121) provided on the first limiting protrusion 311 (or the second limiting protrusion 312), and pushes the first limiting protrusion 311 (or the second limiting protrusion 312) out of the running path of the third boss 23, until the power bank 100 is completely inserted, and there is no interference between the movement of the third boss 23 and the limiting protrusion 31, and then the first moving block 32 (or the second moving block 33) moves close to the first boss 21 under the elastic restoring force of the second elastic member 40, the first limiting protrusion 311 (or the second limiting protrusion 312) enters the running path of the third boss 23, thereby limiting the power bank 100 from being popped out, and achieving the locking of the power bank 100.
[0073] When the power bank 100 is unlocked, the motor drives the drive shaft 41 and the first protrusion 42 to rotate synchronously, the first protrusion 42 contacts the second protrusion 44, thereby pushing the transmission shaft 43, the second protrusion 44, the third protrusion 45 and the fourth protrusion 46 to rotate synchronously, the third protrusion 45 (or the fourth protrusion 46) pushes the first matching block 47 (or the second matching block 48) to move in the process of rotating, thereby driving the first moving block 32 (or the second moving block 33) to move away from the third boss 23, until the first limiting protrusion 311 (or the second limiting protrusion 312) exits the running path of the third boss 23, and the movement of the third boss 23 is not limited, at this time, the hook assembly 2 is reset to the retracted accommodation area 111 under the action of the first elastic member 6, and the first boss 21 is pushed out of the power bank 100 in this process for the user to use.
