For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0055] Reference is made to Figures 1 to 11The utility model embodiment provides a kind of mobile power lock device, for installing in the shared battery compartment of deposit mobile power (specifically between the multiple charging cavities of shared battery compartment, and four charging cavities in this embodiment), to realize the unlocking of power bank in shared battery compartment.Specifically, the mobile power lock device includes shell 1, locking assembly 2 and drive assembly 3, locking assembly 2 and drive assembly 3 are installed on shell 1, drive assembly 3 can drive locking assembly 2 to operate, and then realize the unlocking of power bank.

[0056] Specifically, locking assembly 2 is provided with several, each locking assembly 2 includes locking portion 21 and the first elastic member 22 of driving locking portion 21 to be in the locked state.Drive assembly 3 includes transmission portion, rotary drive portion 31 and pawl portion 32;Transmission portion is correspondingly arranged with locking portion 21, and extends from locking portion 21 to rotary drive portion 31, rotary drive portion 31 is installed at shell 1, and pawl portion 32 is rotatably installed on rotary drive portion 31, and is connected with rotary drive portion 31 by second elastic member 33;When rotary drive portion 31 operates along the first direction, pawl portion 32 can contract along the radial direction to continue to rotate beyond transmission portion;When rotary drive portion 31 operates along the second direction, pawl portion 32 can drive transmission portion to move to drive locking portion 21 to move;The first direction and the second direction are reversely arranged, and the elastic strength of first elastic member 22 is greater than the elastic strength of second elastic member 33.

[0057] In the above scheme, by transmission portion, rotary drive portion 31, pawl portion 32, second elastic member 33, first elastic member 22 and locking portion 21 cooperate with each other, when rotary drive portion 31 drives pawl portion 32 to move along the first direction, pawl portion 32 can contract under the thrust of the overall structure formed by first elastic member 22, locking portion 21 and transmission portion, so that pawl portion 32 can pass transmission portion, and then the adjustment of the position of pawl portion 32 in the circumferential direction can be realized;When pawl portion 32 moves along the second direction, it can also drive transmission portion to move, and then drive locking portion 21 to move, to realize the unlocking of locking portion 21.It can be known that the mobile power lock device of the present scheme can realize the unlocking of multiple locking portions 21 by the same drive assembly 3, reduce the use of drive assembly 3 in mobile power lock device, and then the manufacturing cost and structure size can be reduced, especially when applied to mobile power lock, the size and manufacturing cost of the entire shared battery compartment can be greatly reduced.Moreover, due to the cooperation of first elastic member 22 and second elastic member 33, pawl portion 32 can automatically expand and contract during the rotation of rotary drive portion 31, so that only one power source (i.e., drive motor 38 in the following) can drive the entire locking device, which can further reduce the manufacturing cost of the locking device and reduce the structure size of the locking device.

[0058] Of course, in other embodiments, the second elastic member 33 can not be provided, and the pawl portion 32 can be directly controlled to extend or retract by using a power structure such as a micro motor, a pneumatic cylinder, or an electric push rod.

[0059] It can be understood that the "first direction" is the counterclockwise direction in the orientation shown in the figure, and when the pawl portion 32 operates in this direction, the side of the pawl portion 32 close to the second elastic member 33 is subjected to the force of the transmission portion, so that the pawl portion 32 can retract radially, and the pawl portion 32 can continue to operate beyond the transmission portion. Figure 3 Correspondingly, the "second direction" is the clockwise direction in the orientation shown in the figure, and when the pawl portion 32 operates in this direction, the side of the pawl portion 32 away from the second elastic member 33 is subjected to the force of the transmission portion, at this time, the pawl portion 32 cannot retract, and abuts against the rotary driving portion 31, thereby being able to drive the transmission portion to operate, further driving the locking portion 21 of the locking assembly 2 to move, and achieving unlocking of the power bank. Figure 3

[0060] The locking assembly 2 and the driving assembly 3 can be provided in various matching structures, so that the transmission portion, the rotary driving portion 31, the pawl portion 32, and the second elastic member 33 of the driving assembly 3 are matched with the first elastic member 22 and the locking portion 21 of the locking assembly 2, so that the same driving assembly 3 can achieve unlocking of different locking portions 21.

[0061] Embodiment one

[0062] Referring to Figures 1 to 7 In this embodiment, the rotary driving portion 31 includes a retraction accommodation area 311 and an abutting surface 312; the pawl portion 32 is rotationally installed at a position close to the abutting surface 312 of the retraction accommodation area 311; and the second elastic member 33 is always in a stretched state to drive the pawl portion 32 to abut against the abutting surface 312.

[0063] Specifically, the rotary driving portion 31 is provided as a cylindrical rod, the retraction accommodation area 311 is a notch formed on the cylindrical rod, and the pawl portion 32 is rotationally installed on the rotary driving portion 31 through a cylindrical shaft 313; the pawl portion 32 has a pushing surface 321 and a force-receiving surface 322, one side of the second elastic member 33 is connected to the side of the pawl portion 32 provided with the force-receiving surface 322, and the other end extends away from the retraction accommodation area 311 in a circumferential direction and is connected to the rotary driving portion 31; when the pawl portion 32 is not subjected to an external force, the second elastic member 33 can always pull the pawl portion 32, so that the force-receiving surface 322 of the pawl portion 32 always abuts against the abutting surface 312.

[0064] ​Further, the second elastic member 33 is provided as a tension spring, one end of which is provided with a first tension ear 331, and the other end of which is provided with a second tension ear 332; the pawl part 32 is provided with a first tension ring 4, and the rotary driving part 31 is provided with a second tension ring 5, the first tension ear 331 is hung on the first tension ring 4, and the second tension ear 332 is hung on the second tension ring 5, and the elastic restoring force generated by the tension spring is always directed from the first tension ring 4 to the second tension ring 5. It should be understood that, since the elastic force of the second elastic member 33 is relatively small, and there is at least one stretching and rebounding in each unlocking process, the first tension ear 331, the second tension ear 332, the first tension ring 4 and the second tension ring 5 are matched with each other in the embodiment, so that the second elastic member 33 can be replaced conveniently.

[0065] Referring to Figures 1 to 7 In the embodiment, the locking assemblies 2 are provided in two groups, and the driving assembly 3 is located between the two groups of locking assemblies 2; each locking assembly 2 includes two locking parts 21; the two locking parts 21 are provided opposite to each other and are connected by the first elastic member 22. As can be seen, in the embodiment, one driving assembly 3 can be used to control the unlocking of four power banks, of course, in other embodiments, the locking assemblies 2 can be provided in three groups, four groups or more groups, around the driving assembly 3, so that the driving assembly 3 can drive all the locking parts 21 to unlock.

[0066] For the convenience of description, one of the locking assemblies 2 is taken as an example for description. And the left and right directions in Figure 3 are taken as the left and right directions of the whole power bank locking device for description.

[0067] Referring to Figures 1 to 6 , the first elastic member 22 can be provided as a spring, one end of which is connected with one of the locking parts 21, and the other end of which is connected with the other locking part 21, when the locking parts 21 are not subjected to external force, the first elastic member 22 exerts a force on one of the locking parts 21 in the X1 direction, so that the locking tongue of the locking part 21 extends into the lock hole of the power bank to be locked, thereby realizing the locking of the power bank cooperating with the locking part 21; correspondingly, the first elastic member 22 exerts a force on the other locking part 21 in the X2 direction, thereby realizing the locking of the power bank cooperating with the locking part 21.

[0068] Further, the transmission part corresponding to one of the two locking parts 21 of the locking assembly 2 is provided as a first transmission part 34, and the transmission part corresponding to the other locking part 21 is provided as a second transmission part 35.

[0069] Further, the first transmission part 34 comprises a first protruding part 341, a transmission rod 342 and a first stress protrusion 343; the first protruding part 341 is fixed on the corresponding locking part 21; the transmission rod 342 is rotationally installed on the shell 1, and one end thereof is abutted with the first protruding part 341, and the other end is fixed with the first stress protrusion 343.

[0070] Further, the second transmission part 35 comprises a second protruding part 351 and a second stress protrusion 352; the second protruding part 351 is fixedly connected with the corresponding locking part 21, and the side away from the locking part 21 is fixedly connected with the second stress protrusion 352.

[0071] It can be understood that when the left side of the first stress protrusion 343 of the first transmission part 34 is stressed, the transmission rod 342 can be driven to rotate counterclockwise, so that the other end of the transmission rod 342 pushes the first protruding part 341 in the X1 direction, thereby driving the right locking part 21 to move left (i.e. moving in the X1 direction), achieving the unlocking of the locking part 21 (i.e. the right locking part 21), and in the process, the first elastic member 22 is pressed, and when the left side of the first stress protrusion 343 is not stressed, the locking part 21 (i.e. the right locking part 21) is reset to the locking position under the elastic restoring force of the first elastic member 22. Similarly, when the left side of the second stress protrusion 352 is stressed, the left locking part 21 can be directly driven to move right (i.e. moving in the X2 direction), achieving the unlocking of the locking part 21 (i.e. the left locking part 21), and when the left side of the second stress protrusion 352 is not stressed, the locking part 21 (i.e. the left locking part 21) is reset to the locking position under the elastic restoring force of the first elastic member 22.

[0072] Referring to Figures 1 to 7 , in order to achieve precise control of the entire mobile power supply locking device, in the embodiment, the driving assembly 3 further comprises a sensing block 36 and a control panel 37, and the control panel 37 is provided with an origin sensor 371 for monitoring the origin position of the sensing block 36.

[0073] Further, the control panel 37 is provided with a lock tongue sensor 372 for monitoring the unlocking position of the locking part 21.

[0074] In order to avoid too many internal lines of the entire mobile power supply locking device and ensure the stability of the installation of the origin sensor 371 and the lock tongue sensor 372, in the embodiment, the sensing block 36 is fixed on the end of the rotating driving part 31 extending out of the shell 1; the origin sensor 371 and the lock tongue sensor 372 are both inserted and installed on the control panel 37.

[0075] Further, the induction block 36 comprises a connecting seat 361, a connecting rod 362 and a first extension rod 363, the connecting seat 361 is fixedly installed at one end of the rotating driving part 31 extending out of the shell 1, one end of the connecting rod 362 is connected with the connecting seat 361, and the other end is connected with the first extension rod 363, and the first extension rod 363 can rotate to the induction position of the origin sensor 371.

[0076] Further, the shell 1 is provided with a sunken groove 10 for the rotation of the induction block 36.

[0077] In order to avoid the collision interference of the first extension rod 363 to the origin sensor 371 during the rotation process, and at the same time make the origin sensor 371 more accurate in monitoring, the first extension rod 363 is arranged as a circular arc rod. It can be understood that the first extension rod 363 arranged as a circular arc rod can have a certain width, which is convenient for the origin sensor 371 to monitor, and at the same time the first extension rod 363 can better rotate to the induction position of the origin sensor 371.

[0078] Further, the locking part 21 has a second extension rod 211, which can move to the induction position of the bolt sensor 372.

[0079] It is not difficult to understand that the control board 37 is installed on one side of the shell 1, the origin sensor 371 and the bolt sensor 372 are both inserted and installed on the end face of the control board 37, and the first extension rod 363 and the second extension rod 211 both extend in a direction perpendicular to the end face of the control board 37.

[0080] In order to facilitate the parallel installation of the shell 1 and the control board 37, and avoid the mutual interference of the first extension rod 363 and the origin sensor 371 during the operation process, a plurality of support rods 11 can be fixedly arranged on the shell 1, and the other end of the support rod 11 abuts against the end face of the control board 37.

[0081] Further, the driving assembly 3 further comprises a driving motor 38, and the rotating driving end of the driving motor 38 is at least circumferentially limitedly connected with the rotating driving part 31, so that the driving motor 38 can drive the rotating driving part 31 to operate. Specifically, the driving motor 38 can be arranged as a stepping motor, which is convenient for controlling the rotation angle or time of the driving motor 38 driving the rotating driving part 31, so as to monitor the position of the rotating driving part 31 and the pawl part 32.

[0082] It is worth mentioning that "the rotating driving part 31 is installed at the shell 1" means that the rotating driving part 31 is located at the position of the shell 1. Specifically, the rotating driving part 31 can be directly rotatably installed on the shell 1, at this time, the driving motor 38 can be fixedly installed on the shell 1, and the rotating driving end of the driving motor 38 is connected with the rotating driving part 31 in the circumferential direction. The rotating driving part 31 can also have a gap between the shell 1 (i.e. not connected), for example, the driving motor 38 is fixedly installed on the shell 1, and the rotating driving end of the driving motor 38 extends into the shell 1 and is fixedly connected with the rotating driving part 31 (synchronous limiting in the circumferential direction and the axial direction).

[0083] In summary, the mobile power supply locking device operates as follows:

[0084] In the initial state, all locking parts 21 are in the locked state; the abutting force surface 322 of the pawl part 32 abuts against the abutting surface 312 of the rotating driving part 31 under the action of the second elastic member 33, and is in the extended state, and the pawl part 32 is located between the two adjacent transmission parts, and the first extension rod 363 is located at the position of the original point sensor 371. It is not difficult to understand that, as preferred, "the pawl part 32 is located between the two adjacent transmission parts" means that the pawl part 32 is located at the midpoint of the line connecting the two transmission parts (for details, please refer to the initial position of the pawl part 32 in the embodiment Figure 8 not shown in the embodiment) of the pawl part 32. Of course, in other embodiments, the pawl part 32 can also be located only between the two transmission parts, at this time, the corresponding rotation angle synchronous adaptive adjustment is controlled when the pawl part 32 rotates, which can ensure that the pawl part 32 can operate to the preset position. Figures 1-7

[0085] Referring to Figures 1 to 7 When it is necessary to unlock, for example, one of the locking parts 21 (such as the locking part 21 at the upper right corner in the figure) Figure 3 , the rotating driving part 31 is driven counterclockwise by the driving motor 38, and during the rotation, when the side of the pawl part 32 connected with the second elastic member 33 abuts against the first transmission part 34, since the elastic strength of the first elastic member 22 is smaller than that of the second elastic member 33, and the first transmission part 34 cannot act, the pawl part 32 is retracted into the retracted accommodation area 311, and when the pawl part 32 rotates 90° (or operates to the left side of the first stress protrusion 343), the rotating driving part 31 is driven clockwise by the driving motor 38, and during the process, the abutting force surface 322 of the pawl part 32 always abuts against the abutting surface 312, thereby pushing the transmission rod 342 to rotate, and further driving the corresponding locking part 21.

[0086] It can be understood that when it is necessary to drive Figure 3 ​When the locking part 21 at the top left corner is to be unlocked, the driving motor 38 drives the rotating driving part 31 to rotate counterclockwise by 180° (in this process, the pawl part 32 can pass the second transmission part 35), and then rotate clockwise to push the second transmission part 35, and further push the corresponding locking part 21 to be unlocked; when the locking part 21 at the top right corner is to be unlocked, the driving motor 38 drives the rotating driving part 31 to rotate counterclockwise by 90°, and then rotate clockwise to push the second transmission part 35, and further push the corresponding locking part 21 to be unlocked. Figure 3 When the locking part 21 at the bottom left corner is to be unlocked, the driving motor 38 drives the rotating driving part 31 to rotate counterclockwise by 270°, and then rotate clockwise to push the second transmission part 35, and further push the corresponding locking part 21 to be unlocked. When the locking part 21 at the bottom right corner is to be unlocked, the driving motor 38 directly drives the rotating driving part 31 to rotate clockwise to drive the pawl part 32 to drive the transmission part corresponding to the locking part 21. Figure 4

[0087] When the locking part 21 at the bottom right corner is to be unlocked, the driving motor 38 directly drives the rotating driving part 31 to rotate clockwise to drive the pawl part 32 to drive the transmission part corresponding to the locking part 21.

[0088] In addition, it should be understood that in the above scheme, the original point sensor 371 is used to judge whether the initial state is restored, and then the driving motor 38 is controlled to stop, so that the monitoring result is more accurate.

[0089] In other embodiments, only the locking sensor 372 can be used to judge whether the entire device is restored to the initial state, so as to reduce the investment of sensors and reduce the cost.

[0090] In other embodiments, no sensor can be directly set, the angle of the rotating driving part 31 controlled by the driving motor 38 itself is monitored to judge whether the initial state or real-time position is restored, so as to reduce the investment of sensors and reduce the cost. In this state, preliminary calibration can be realized after the entire mobile power supply locking device is assembled. For example, the original point positions of the rotating driving part 31, the pawl part 32 and the sensing block 36 can be directly positioned during assembly; then, after the mobile power supply locking device is assembled, the initial data of the rotating driving part 31 rotating one round (i.e. 360°) is monitored in advance, such as the time required for one round, so as to drive the rotating driving part 31 to operate based on the initial data to judge the actual position of the rotating driving part 31 during rotation, and then drive the rotating driving part 31 and the pawl part 32 to operate to the original point position after the corresponding locking part 21 is unlocked. Specifically, the same time and angle during the unlocking process can be used.

[0091] Embodiment Two

[0092] Referring to Figures 8 to 10 ​, based on the above embodiment one, the difference of the embodiment is that the second transmission part 35 includes the third stress convex 353 and the driving slider 354, the third stress convex 353 is fixedly connected with the corresponding locking part 21, the driving slider 354 is slidingly installed on the shell 1, the first guide inclined surface 3531 is arranged on the third stress convex 353, and the second guide inclined surface 3541 is arranged on one side of the driving slider 354 and corresponds to the first guide inclined surface 3531.

[0093] Specifically, the driving slider 354 is installed in the guide groove, and the sliding direction of the driving slider 354 and the sliding direction of the third stress convex 353 are perpendicular to each other. It is not difficult to understand that the pawl part 32 slides through the driving slider 354, further drives the third stress convex 353 and the corresponding locking part 21 to slide and be unlocked.

[0094] It is worth noting that, based on the above embodiment one and embodiment two, it can be known that the embodiment one can make the structure more compact, can not set the driving slider 354, and further reduce the manufacturing cost and product size, and the embodiment two can save more labor, and can avoid the deformation of the stress structure, especially when the stress structure is set as an injection molding part. In order to verify the effect, and further verify the labor saving, the specific steps are as follows:

[0095] Referring to Figure 3 (embodiment one), the stress analysis of this scheme is as follows:

[0096] The stress analysis of the locking part 21 is that, since the locking part 21 moves to the left, the resultant force in the horizontal direction of the locking part 21 is to the left, that is,

[0097] F4*cosJ1≥f4+G1

[0098]

[0099] Wherein, the friction force of the shell 1 to the locking part 21 is f4; the driving force of the driving motor 38 is F4; the elastic force of the first elastic member 22 to the locking part 21 is G1, the angle between the force of the pawl part 32 to the locking part 21 and the horizontal plane is J1, and 0

[0100] Referring to Figures 8 to 10 (embodiment two), the stress analysis of this scheme is as follows:

[0101] The horizontal direction mechanical calculation of the locking part 21 is that, since the locking part 21 moves to the left, it is explained that the horizontal direction resultant force is to the left, that is: F1*cosJ2≥G1+f3+f1*cosJ2;

[0102] In the vertical direction, the slider moves downward due to the driving force, which indicates that the resultant force in the vertical direction is downward, i.e., F0≥f1*sinJ2+f2+F1*cosJ2≥f1*sinJ2+f2+G1+f3+f1*cosJ2;

[0103] After simplification: F0≥f1*(sinJ2+cosJ2)+f2+f3+G1

[0104] wherein the frictional force of the locking portion 21 against the driving slider 354 is f1; the frictional force of the shell 1 against the driving slider 354 is f2; the frictional force of the shell 1 against the locking portion 21 is f3; the driving force of the driving motor 38 is F0; the normal pressure between the driving slider 354 and the locking portion 21 is F1; the supporting force of the shell 1 against the locking portion 21 is N1; the included angle between the inclined surface (the second guide inclined surface 3541) between the driving slider 354 and the locking portion 21 and the horizontal plane is J2, and 0

[0105] As can be seen from the above, since 0 , the driving force in the embodiment one is greater than that in the embodiment two, i.e., the driving force required in the embodiment one is greater than that in the embodiment two.

[0106] Embodiment three

[0107] Referring to Figure 11 Based on the above embodiment one, the difference between the embodiment and the above embodiment one lies in that the first transmission portion 34 comprises a transmission rod 342 and a first stress protrusion 343, the transmission rod 342 is rotatably installed on the shell 1, and one end thereof is connected with the corresponding locking portion 21, and the other end is fixedly provided with the first stress protrusion 343.

[0108] Further, in the embodiment, the transmission rod 342 is fixedly connected with the corresponding locking portion 21, of course, in other embodiments, the transmission rod 342 can also be rotatably connected or clamped with the locking portion 21. When the first stress protrusion 343 of the transmission rod 342 is stressed, the transmission rod 342 can be driven to swing, and then the corresponding locking portion 21 is driven to move (differently from the embodiment one, the specific movement mode in the embodiment is swinging) to be unlocked.

[0109] It is not difficult to understand that the first transmission portion 34 and the second transmission portion 35 can be provided in various structures, and they can be stressed at one end, and the stress can be transmitted to the corresponding locking portion 21, and then the corresponding locking portion 21 can be driven to move to be unlocked.

[0113] The pawl part 32 is driven by the rotating driving part 31 to rotate in the second direction, and the pawl part 32 is in abutment with the rotating driving part 31 during the rotation to drive the locking part 21 to move.

[0114] Further, the method further comprises the following steps:

[0115] The mobile power source locking device is assembled, and the rotating driving part 31 and the pawl part 32 are in the original position;

[0116] After the mobile power source locking device is assembled, the rotating driving part 31 is driven to rotate one round, and the initial data of the one round rotation is recorded;

[0117] According to the initial data, the rotating driving part 31 is driven to rotate to judge the actual position of the rotating driving part 31 during the rotation, and after the corresponding locking part 21 is unlocked, the rotating driving part 31 and the pawl part 32 are driven to rotate in the first direction to the original position.

[0118] It is worth mentioning that the initial data comprises the time of driving the rotating driving part 31 and the pawl part 32 to rotate one round.

[0119] Further, the method further comprises the following steps:

[0120] The original position of the rotating driving part 31 and the pawl part 32 is monitored by the original position sensor 371;

[0121] And / or,
