This embodiment provides a bolt driving mechanism and an unlocking device that can reduce the use cost and ensure the accuracy of unlocking and locking during long-term use.

FIG. 1 is a schematic diagram of the three-dimensional structure of the unlocking device in this embodiment.

1 , the embodiment of the utility model provides an unlocking device 100, which is used to lock or unlock a locked object, and includes a lock tongue 100a and a lock tongue driving mechanism 100b. The lock tongue driving mechanism 100b is used to drive the lock tongue 100a to unlock or lock.

In this embodiment, the locking object is a power bank. Of course, in other alternative embodiments, the locking object can also be other items that need to be locked.

Figure 2 is a schematic diagram of the three-dimensional structure of the lock tongue driving mechanism in this embodiment; Figure 3 is a schematic diagram of the cross-sectional structure of the lock tongue driving member in this embodiment when it is in its yielding position; Figure 4 is a schematic diagram of the cross-sectional structure of the lock tongue driving member in this embodiment when it is in its driving position.

As shown in conjunction with Figures 2 to 4, the bolt drive mechanism 100b includes a housing 10, a bolt drive member 20, a drive motor 30, a first limiting structure 40, and a second limiting structure 50. The bolt drive member 20 is rotatably disposed in the housing 10 and connected to the bolt 100a, and can rotate between a driving position for enabling the bolt 100a to perform a locking action and a yielding position for enabling the bolt 100a to perform an unlocking action. The drive motor 30 is disposed in the housing 10 and connected to the bolt drive member 20. The first limiting structure 40 includes a first blocking portion 41 disposed on the housing 10 and a first blocking matching portion 42 disposed on the bolt drive member 20, and when the first blocking portion 41 abuts against the first blocking matching portion 42, the bolt drive member 20 is in the yielding position. The second limiting structure 50 includes a second blocking portion 51 disposed on the housing 10 and a second blocking matching portion 52 disposed on the bolt driver 20 . When the second blocking portion 51 abuts against the second blocking matching portion 52 , the bolt driver 20 is in the driving position.

It can be understood that when it is necessary to lock the power bank, the driving motor 30 is used to drive the lock tongue driving member 20 to rotate to the driving position, so that the lock tongue 100a performs a locking action. During this rotation process, the second blocking matching portion 52 rotates synchronously with the lock tongue driving member 20. When the second blocking portion 51 abuts against the second blocking matching portion 52, the lock tongue driving member 20 passively stops at the driving position, thereby enabling the lock tongue driving member 20 to accurately stop at the driving position through the abutment and cooperation between the second blocking portion 51 and the second blocking; when it is necessary to unlock the power bank, the driving motor 30 is used to drive the lock tongue driving member 20 to rotate to the yielding position, so that the lock tongue 100a can perform an unlocking action. During the movement, the first blocking matching portion 42 rotates synchronously with the lock tongue driving member 20. When the first blocking portion 41 abuts against the first blocking matching portion 42, the lock tongue driving member 20 passively stops at the yielding position. Therefore, the lock tongue driving member 20 can be accurately stopped at the yielding position through the abutment and cooperation between the first blocking portion 41 and the first blocking. Therefore, there is no need to use a motor with high control precision or a motor with a braking function. As the number of unlocking and locking increases, the first limiting structure 40 and the second limiting structure 50 are difficult to be damaged, and the limiting function can be stably and reliably realized, thereby reducing the use cost and ensuring the accuracy of unlocking and locking during long-term use.

In this embodiment, the driving motor 30 is a reduction motor, and the bolt driving member 20 is fixed on the output shaft of the driving motor 30 .

FIG. 5 is a schematic diagram of the matching structure of the lock tongue driving member and the limiting groove in this embodiment.

As shown in combination with FIG3 and FIG5 , a limiting groove 11 is provided on the side wall of the housing 10 and is aligned with the bolt driver 20, and the width of the limiting groove 11 is greater than the thickness of the bolt driver 20. One side wall of the limiting groove 11 is located on the rotation path of the bolt driver 20, and the side wall constitutes a first blocking portion 41, and a portion of the circumferential outer wall of the bolt driver 20 corresponding to the side wall constitutes a first blocking matching portion 42.

It can be understood that the lock tongue driving component 20 can enter the limiting groove 11 when it rotates. When the lock tongue driving component 20 rotates a certain angle, it can abut against the side wall of the limiting groove 11. After the abutment, the lock tongue driving component 20 is blocked at the current position, so that the lock tongue driving component 20 can be accurately stopped at the yielding position.

As shown in FIG. 5 , in this embodiment, the limiting groove 11 is a rectangular through groove provided on the side wall of the housing 10 , and A in the figure shows the width of the limiting groove 11 , and B in the figure shows the thickness of the bolt drive member 20 .

As shown in FIG4 , the inner wall of the housing 10 is provided with a first protrusion 12 aligned with the bolt driver 20, and the circumferential outer wall of the bolt driver 20 is provided with a second protrusion 21 for blocking and cooperating with the first protrusion 12. The first protrusion 12 is located on the path of the second protrusion 21 rotating with the bolt driver 20, the first protrusion 12 constitutes a second blocking portion 51, and the second protrusion 21 constitutes a second blocking and cooperating portion 52.

It can be understood that when the lock tongue driving member 20 rotates, it can drive the second protrusion 21 to rotate synchronously. After the lock tongue driving member 20 rotates a certain angle, the second protrusion 21 can abut against the first protrusion 12. After the abutment, the lock tongue driving member 20 is blocked at the current position, so that the lock tongue driving member 20 can stop accurately at the driving position.

In this embodiment, the first protrusion 12 is disposed on the circumferential outer wall of the bolt driving member 20 and is integrally formed with the bolt driving member 20 , and the second protrusion 21 is integrally formed with the side wall of the housing 10 .

It should be noted that, in the present embodiment, the driving position and the yielding position of the lock tongue driving member 20 are 90° apart. When the lock tongue driving member 20 is in the driving position, the first blocking portion 41 and the first blocking matching portion 42 are 90° apart in the rotation direction of the lock tongue driving member 20. When the lock tongue driving member 20 is in the yielding position, the second blocking portion 51 and the second blocking matching portion 52 are 90° apart in the rotation direction of the lock tongue driving member 20.

FIG6 is a schematic cross-sectional view of the lock tongue in the unlocked position according to the present embodiment; FIG7 is a schematic cross-sectional view of the lock tongue in the locked position according to the present embodiment.

As shown in Figures 6 and 7, the lock tongue 100a is movably arranged on the housing 10 and has a locking position and an unlocking position. In the locking position, the lock tongue 100a forms a locking fit with the locked object to achieve locking, and in the unlocking position, the lock tongue 100a and the locked object are disengaged from the locking fit to achieve unlocking. The lock tongue 100a includes a locking end extending to the outside of the housing 10 and a connecting end located inside the housing 10. The lock tongue driving member 20 abuts against the connecting end on the lock tongue 100a to form a driving fit.

It can be understood that when the lock tongue driving member 20 is rotated to the driving position, it can drive the lock tongue 100a to move to the locking position, so that the lock tongue 100a forms a locking fit with the power bank; when the lock tongue driving member 20 is rotated to the yielding position, the lock tongue 100a can be moved to the unlocking position, so that the lock tongue 100a can be disengaged from the locking fit with the power bank, and because the lock tongue driving member 20 drives the lock tongue 100a to move to the locking position by abutting with the connecting end on the lock tongue 100a, therefore, when the lock tongue 100a is in the locking position, the lock tongue driving member 20 is always abutted with the connecting end on the lock tongue 100a, so that the lock tongue 100a is restricted in the locking position, thereby effectively preventing the power bank from being stolen.

It should be noted that the power bank is provided with a recess that matches the locking end of the lock tongue 100a, and the locking end of the lock tongue 100a is inserted into the recess when locking, and is pulled out of the recess when unlocking. The recess can be a lock hole, a lock groove, etc.

FIG. 8 is a schematic diagram of the three-dimensional structure of the lock tongue driving member in this embodiment.

As shown in FIG8 , the bolt driver 20 includes a rotating main body 22 and an abutting driving part 23. Along the circumferential outer wall of the rotating main body 22, the rotating main body 22 includes a first area and a second area. When the second area of the rotating main body 22 abuts against the bolt 100a, the bolt 100a is in the unlocking position. The abutting driving part 23 is convexly arranged in the first area to abut against the bolt 100a when the bolt driver 20 is in the driving position to make it in the locking position.

It can be understood that when the rotating main body 22 rotates, the abutting driving part 23 can rotate synchronously with the rotating main body 22. When the lock tongue driving member 20 rotates to the driving position, the abutting driving part 23 can abut the connecting end of the lock tongue 100a to move the lock tongue 100a to the locking position. When the lock tongue driving member 20 reaches the driving position, the abutting driving part 23 continues to abut the connecting end of the lock tongue 100a to restrict the lock tongue 100a in the locking position. Thus, the lock tongue 100a can be restricted in the locking position by the abutting driving part 23, and the lock tongue 100a can also be driven to move to the locking position, thereby locking the power bank. In addition, by abutting and cooperating with the second area of the rotating main body 22 and the lock tongue 100a, the lock tongue 100a can be abutted when the lock tongue driving member 20 is in the yielding position to make the lock tongue 100a in the unlocking position, thereby restricting the lock tongue 100a in the unlocking position, thereby unlocking the power bank.

In this embodiment, the rotating main body 22 is disc-shaped and is integrally formed with the abutting driving part 23. Along the circumferential outer wall of the rotating main body 22, the abutting driving part 23 includes an abutting driving surface 231 and an abutting limiting surface 232. The abutting driving surface 231 is an arc surface, and the abutting limiting surface 232 is a plane. The abutting driving surface 231 abuts against the connecting end of the lock tongue 100a to drive the lock tongue 100a to move to the locking position, and the abutting limiting surface 232 abuts against the connecting end of the lock tongue 100a to limit the lock tongue 100a in the locking position. The abutting driving part 23 also includes a blocking surface 233, and the blocking surface 233 constitutes the first blocking part 41.

In this embodiment, the first protrusion 12 is disposed in the second region of the rotating body 22 and is integrally formed with the rotating body 22. The rotating body 22 is fixed to the output shaft of the driving motor 30.

6 to 7 , the unlocking device 100 further includes a reset member 60 disposed in the housing 10 for moving the lock tongue 100a from the locked position to the unlocked position when the lock tongue driving member 20 rotates from the driving position to the yielding position.

It can be understood that when the lock tongue driving member 20 rotates to the yielding position, the lock tongue 100a moves to the unlocking position under the action of the reset member 60, so that the lock tongue 100a and the power bank are out of locking cooperation.

6 to 7 , the reset member 60 is a compression spring, which is sleeved on the lock tongue 100 a , with one end abutting against the inner wall of the housing 10 , and the other end abutting against the outer wall of the lock tongue 100 a directly or indirectly.

It can be understood that when the lock tongue 100a is in the locked position, the reset member 60 is in a compressed and force-accumulated state. During the rotation of the lock tongue drive member 20 to the yield position, the abutment drive portion 23 no longer applies a thrust to the lock tongue 100a. The lock tongue 100a moves to the unlocked position under the action of the reset member 60, and then abuts against the second area of the rotating main body 22.

In this embodiment, one end of the reset member 60 abuts against the inner wall of the housing 10 , and the other end abuts against the side wall of the synchronous moving member 71 .

FIG. 9 is a schematic diagram of the three-dimensional structure of the locking monitoring mechanism in this embodiment.

In conjunction with shown in Figure 9, the unlocking mechanism also includes a locking monitoring mechanism 70, which is used to monitor whether the deadbolt 100a moves to the locked position, and includes a synchronous moving member 71, a photoelectric switch 72 and a switch triggering portion 73. The synchronous moving member 71 is fixed on the deadbolt 100a. The photoelectric switch 72 is used to send a signal when the deadbolt 100a moves to the locked position. The switch triggering portion 73 is fixed on the synchronous moving member 71, and is used to trigger the photoelectric switch 72 when the deadbolt 100a moves to the locked position.

It can be understood that when the lock tongue 100a moves to the locked position, the synchronous moving part 71 moves synchronously with the lock tongue 100a, thereby driving the switch trigger part 73 to move to the side where the photoelectric switch 72 is located. When the switch trigger part 73 moves to the position corresponding to the photoelectric switch 72, the switch trigger part 73 blocks the light beam emitted by the photoelectric switch 72, thereby triggering the photoelectric switch 72 to send a signal, thereby prompting the lock tongue 100a that it has moved to the locked position.

In this embodiment, the photoelectric switch 72 is disposed outside the housing 10 and fixed to the charging compartment body. The housing 10 has an opening for the switch triggering portion 73 to move to the outside of the housing 10. The photoelectric switch 72 has a light-through hole 721 on the movement path of the switch triggering portion 73 along the lock tongue 100a. When the switch triggering portion 73 enters the light-through hole 721, the photoelectric switch 72 is triggered to send a signal. When the lock tongue 100a is in the unlocked position, the distance between the locked position and the unlocked position of the lock tongue 100a is consistent with the distance between the photoelectric switch 72 and the switch triggering portion 73.

9, a guide rod 711 is provided on the synchronous moving member 71, one end of the guide rod 711 is fixed to the synchronous moving member 71, and the other end slides through the side wall of the housing 10 for guiding the synchronous moving member 71 during the movement of the locking tongue 100a.

It can be understood that the guide rod 711 can ensure the stability of the synchronous moving member 71 when it moves with the lock tongue 100 a, and can limit the synchronous moving member 71 from moving in a predetermined direction so as to accurately trigger the photoelectric switch 72 .

The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
