Referring to fig. 1-3, the present invention provides an unlocking mechanism 100. The unlocking mechanism 100 is applied to a computer key A to realize locking and unlocking operations of a lock. The utility model discloses an unlocking mechanism 100 has folding function, simultaneously, can also guarantee electrical connection's reliability, and then guarantees computer key A's performance to, the integrated level is high, simple structure, convenient to use operation.

Referring to fig. 2-7, in one embodiment, the unlocking mechanism 100 includes an unlocking assembly 110 and an electrical assembly 120. The unlocking assembly 110 is a main component of the unlocking mechanism 100 for unlocking and locking the lock, and meanwhile, the unlocking component can also realize the folding function of the unlocking mechanism 100. The electrical component 120 enables identity acquisition and open-close lock state acquisition of the lock.

Specifically, the unlocking assembly 110 includes a bracket 113, a rotating block 115 and an unlocking blade 111, the rotating block 115 is rotatably disposed on the bracket 113, the unlocking blade 111 is disposed on the rotating block 115 and rotates with the rotating block 115 to enable the rotating block 115 to be in an operating position or a non-operating position, and the bracket 113 has a blade accommodating area 1136 for accommodating the unlocking blade 111 in the non-operating position. The electrical component 120 is disposed on the rotation block 115; the electrical assembly 120 includes a code reading detecting member and a flexible transmission member 123 electrically connected to the code reading detecting member, and the code reading detecting member is connected to an end of the flexible transmission member 123.

Referring to fig. 2 to 4, the bracket 113 has a first receiving cavity 1133, and the rotating block 115 is rotatably mounted to the first receiving cavity 1133. In this way, the rotation block 115 does not expose the bracket 113, and the hidden function of the unlocking mechanism 100 is realized. The blade of the unlocking blade 111 has a mechanical unlocking portion. After the unlocking blade 111 extends into the lock, the unlocking blade can be matched with a lock cylinder component of the lock to realize the locking and unlocking of the lock. The other end of the unlocking blade 111 also has a mounting portion, the rotating block 115 has a second receiving cavity 1151, and the unlocking blade 111 is mounted in the second receiving cavity 1151 of the rotating block 115 through the mounting portion. Alternatively, the unlocking blade 111 is fixedly mounted on the rotating block 115 by a fixing structure such as a pin, a screw, a snap, or the like. Thus, the rotation of the rotating block 115 can drive the unlocking blade 111 to rotate synchronously.

Also, when the rotary block 115 is rotated, the unlocking blade 111 has two positions, one is an operating position and the other is a non-operating position. The rotation block 115 may effect the switching of the unlocking blade 111 between the working position and the non-working position. When the unlocking blade 111 is in the working position, the unlocking blade 111 is exposed from the bracket 113, and at this time, the unlocking blade 111 can extend into the lock to perform the locking and unlocking operation. When the unlocking blade 111 is in the non-working position, the unlocking blade 111 is hidden in the bracket 113 and is located in the blade accommodating area 1136 of the bracket 113, so that the size of the computer key a is reduced, and the computer key a is convenient to store.

As can be appreciated, the blade receiving area 1136 can achieve complete storage of the unlocking blade 111, so that the unlocking blade 111 can be completely hidden, and the protective performance of the unlocking blade 111 when not in operation is ensured. Further, the difference between the working position and the non-working position of the unlocking blade 111 is 180 °, so that the unlocking blade 111 can be conveniently switched between the working position and the non-working position.

The electrical component 120 is disposed in the rotating block 115 and can rotate together with the rotating block 115. The flexible transmission member 123 is used for transmitting information. Specifically, the code reading detection piece can read the identity code value that the tool to lock corresponds and gather the switching lock state of tool to lock to pass through flexible transmission piece 123 with the identity code value of tool to lock and switching lock state information and transmit the control module for the computer key, discern the matching with the identity information to the tool to lock, whether corresponding with the tool to lock with the judgement computer key A. In addition, the flexible transmission member 123 can also feed the current state of the lock back to the computer key control module, the control module of the computer key can judge whether the current state of the lock is accurate, and the flexible transmission member 123 feeds back the next working state of the lock, so that the operation accuracy is ensured, and meanwhile, the operator is prompted to perform the next operation.

Because the motion of rotatory piece 115 during operation is the rotary motion, lead to the unstable problem of electrical connection that the circuit board takes place to buckle to lead to when avoiding rotatory piece 115 to rotate. The utility model discloses release mechanism 100 adopts flexible transmission piece 123 to connect and reads the sign indicating number and detect the piece. The flexible transmission member 123 has the characteristic of flexibility, and the flexible circuit board is not damaged when the rotating block 115 rotates, so that the electrical connection stability is ensured.

In one embodiment, the flexible transmission member 123 is spirally wound, the code reading detection member is connected to one end of the flexible transmission member 123, and the other end of the flexible transmission member 123 penetrates through the bracket 113 to extend out. Because the motion of rotatory piece 115 during operation is rotary motion, leads to the circuit board to take place to buckle the unstable problem of electrical connection that leads to when avoiding rotatory piece 115 to rotate, the utility model discloses flexible transmission piece 123 among release mechanism 100 adopts the winding structure of heliciform. It can be understood that the spiral flexible transmission member 123 may be tapered after being wound, that is, the spiral inner ring and the spiral outer ring are not coplanar; or the spiral inner ring and the spiral outer ring are coplanar. In this embodiment, the flexible transmission member 123 is spirally wound and then is planar.

Optionally, the flexible transmission member 123 includes, but is not limited to, a flexible circuit board, and may also be a flexible cable or other transmission component with flexible characteristics. Illustratively, the flexible transmission member 123 is a flexible wiring board. When the flexible transmission member 123 is a flexible cable, the flexible cable is spirally wound in an up-and-down stacked manner, one end of the flexible cable is connected with the code reading detection member, and the other end of the flexible cable passes through the bracket 113 to extend out.

Referring to fig. 2, 3 and 7, the code-reading detecting member is connected to one end of the flexible transmission member 123, and the other end of the flexible transmission member 123 protrudes through the bracket 113. It is understood that the other end of the flexible transmission member 123 has a connection joint for connecting non-bendable components, such as a power supply, a control module, etc. The rotation block 115 can drive the code reading detection part to rotate synchronously when rotating, and because the section of each circle of the spiral flexible transmission part 123 is circular, the track of the spiral flexible transmission part 123 when rotating is also similar to circular, and the circle of the flexible transmission part 123 can be released or continuously screwed to complete the change of the diameter of the approximate circle. Thus, when one end of the flexible transmission member 123 rotates, the other end of the flexible transmission member 123 does not need to rotate, and the flexible transmission member 123 is not bent, so that the flexible transmission member 123 is prevented from being damaged when the rotating block 115 rotates, and the reliability of connection of an electric appliance is improved.

The utility model discloses an unlocking mechanism 100 adopts spiral helicine flexible transmission piece 123 cooperation rotatory piece 115 after, and flexible transmission piece 123 buckles when can avoiding unblock blade 111 to rotate, prevents to the damage of flexible transmission piece 123, and effectual solution computer key A exists the unstable problem of electrical connection at present, improves electrical connection's reliability, and then guarantees computer key A's performance. And simultaneously, the utility model discloses a structural mechanism still integrates rotatory piece 115, unblock blade 111 and reads the sign indicating number and detects the piece, and the integrated level is high, simple structure, and the operating personnel of being convenient for uses.

In one embodiment, the code-reading detecting member is connected to the outer end of the flexible transmission member 123, and the inner end of the flexible transmission member 123 extends out of the bracket 123. As shown in fig. 2, 3, 5 and 7, when the rotation block 115 drives the code reading detection member to rotate synchronously, the code reading detection member drives the outer ring of the flexible transmission member 123 to rotate. At this time, the outer ring of the flexible transmission member 123 may be continuously wound inward or released outward. Therefore, the outer ring of the flexible transmission piece 123 cannot drive the inner ring to move, and further, the part connected with the inner ring is in a static state, so that bending cannot be generated, and the reliability of electrical connection is ensured. Optionally, the number of spiral turns of the flexible transmission member 123 is more than three, so that the influence of the rotation of the outer ring of the flexible transmission member 123 on the inner ring can be avoided,

of course, in other embodiments of the present invention, the code reading detecting member is connected to the inner ring end of the flexible transmission member 123, and the outer ring end of the flexible transmission member 123 extends out of the bracket 123. It is understood that the principle of this method is substantially the same as the above embodiments, and the description thereof is omitted.

Referring to fig. 2 to 6, in an embodiment, the unlocking member 110 further includes an unlocking member, the rotating block 115 has a first through hole 1154, the bracket 113 has a second through hole 1131 coaxial with the first through hole 1154, and the unlocking member is mounted on the rotating block 115 and extends out of the bracket 113 through the first through hole 1154 and the second through hole 1131. The unlocking member is used to unlock or lock the unlocking blade 111 in the operating position and the non-operating position. It will be appreciated that the unlocking member can keep the rotating block 115 and the unlocking blade 111 thereon in a stable state, i.e. when the rotating block 115 is in the working position, the unlocking blade 111 does not move to the non-working position by itself; when the rotary block 115 is in the non-operating position, the unlocking blade 111 does not move to the operating position by itself.

When the unlocking blade 111 needs to be switched from the working position to the non-working position, the unlocking member is operated, and at this time, the rotating block 115 and the unlocking blade 111 can be synchronously moved to the non-working position. When the unlocking blade 111 needs to be switched from the non-working position to the working position, the rotating block 115 and the unlocking blade 111 can synchronously move to the working position by operating the unlocking piece. It can be understood that the unlocking member may adopt a rotating manner to unlock and lock the rotating block 115, may also adopt a pressing manner to unlock and lock the rotating block 115, and may also adopt other structures capable of unlocking and locking the rotating block 115. And, the unlocking member also functions as a rotation shaft so that the rotation block 115 is rotated with respect to the bracket 113 by the unlocking member.

Illustratively, the unlocking member unlocks and locks the rotating block 115 by pressing. Specifically, the unlocking member includes an unlocking button 112 and an unlocking spring 117, the unlocking button 112 is installed on the rotating block 115 and penetrates through the first through hole 1154 and the second through hole 1131, one end of the unlocking spring 117 abuts against the bracket 113, and the other end of the unlocking spring 117 extends into the unlocking button 112. The unlocking button 112 has a positioning rib 1121 extending in the radial direction on the peripheral side thereof, the inner wall of the first through hole 1154 has a first positioning groove 1155, and the inner wall of the second through hole 1131 has a second positioning groove 1134 arranged coaxially with the first positioning groove 1155. Under the elastic force of the unlocking spring 117, the positioning rib 1121 may extend into the second positioning groove 1134 through the first positioning groove 1155, for locking the rotating block 115; pressing the unlock button 112 moves the positioning rib 1121 out of the second positioning groove 1134 for unlocking the rotation block 115.

It will be appreciated that an end of the unlocking button 112 remote from the rotary block 115 protrudes from the surface of the bracket 113. After the unlocking button 112 is matched with the first positioning groove 1155 of the rotating block 115 through the positioning rib 1121, the unlocking button 112 and the rotating block 115 can rotate synchronously. Furthermore, the positioning rib 1121 can also be extended into the second positioning groove 1134 of the bracket 113 through the rotating block 115 to limit the action of the unlocking mechanism 100. That is, when the positioning rib 1121 of the unlocking button 112 simultaneously passes through the first positioning groove 1155 of the rotating block 115 and the second positioning groove 1134 of the bracket 113, the second positioning groove 1134 of the bracket 113 circumferentially limits the positioning rib 1121, and the rotating block 115 and the unlocking button 112 cannot rotate relative to the bracket 113; when the positioning rib 1121 of the unlocking button 112 only passes through the first positioning groove 1155 of the rotating block 115, the bracket 113 no longer circumferentially limits the positioning rib 1121, and the unlocking button 112 and the rotating block 115 can rotate relative to the bracket 113.

Thus, when the unlocking button 112 is pressed, the unlocking button 112 moves inward, i.e., toward the rotating block 115, at this time, the positioning rib 1121 of the unlocking button 112 is separated from the second positioning groove 1134 of the bracket 113 and is only located in the first positioning groove 1155 of the rotating block 115, the second positioning groove 1134 of the bracket 113 does not limit the displacement of the positioning rib 1121, the rotating block 115 and the unlocking blade 111 can rotate relative to the bracket 113, and the unlocking of the rotating block 115 and the unlocking button 112 is realized. After the unlocking button 112 is released, the unlocking button 112 automatically resets under the elastic force of the unlocking spring 117, so that the positioning rib 1121 of the unlocking button 112 extends into the second positioning groove 1134 of the bracket 113 along the first positioning groove 1155 of the rotating block 115, and the second positioning groove 1134 of the bracket 113 limits the displacement of the positioning rib 1121, thereby locking the rotating block 115 and the unlocking button 112.

It can be understood that, when the number of the positioning ribs 1121 is one, the second limiting grooves may be disposed at both the working position and the non-working position of the bracket 113 corresponding to the unlocking blade 111. This allows the unlocking blade 111 to be locked and unlocked in both the working position and the non-working position.

Of course, in another embodiment of the present invention, the number of the positioning ribs 1121 is plural, and the plural positioning ribs 1121 are disposed on the peripheral side of the unlock button 112 in a central symmetry manner. The number of the positioning ribs 1121 is the same as that of the first positioning grooves 1155; the arrangement position of the positioning ribs 1121 coincides with the arrangement position of the first positioning grooves 1155. That is, after the unlocking blade 111 is switched between the working position and the non-working position, the plurality of positioning ribs 1121 of the unlocking button 112 may be respectively inserted into the second positioning grooves 1134 of the bracket 113.

Illustratively, the number of the positioning ribs 1121 is two, and the two positioning ribs 1121 are symmetrically disposed on the peripheral side of the unlocking button 112. That is to say that the two positioning ribs 1121 are 180 ° out of phase with each other. Accordingly, the number of the first positioning grooves 1155 and the second positioning grooves 1134 is two, and the positions of the first positioning grooves and the second positioning grooves correspond to the positions of the positioning ribs 1121 respectively. When locked, the two positioning ribs 1121 extend into the second positioning grooves 1134 through the corresponding first positioning grooves 1155, and when unlocked, the two positioning ribs 1121 simultaneously move out of the second positioning grooves 1134.

In an embodiment, the peripheral side of the unlocking button 112 further has a limiting rib 1122, and the limiting rib 1122 extends out of the positioning rib 1121 in the circumferential direction. The inner wall of the first through hole 1154 has a stopper surface 1156, and the stopper surface 1156 faces the unlocking spring 117. The limiting rib 1122 abuts against the limiting surface 1156 to limit the extending displacement of the unlocking button 112 along the second through hole 1131. That is, the limit rib 1122 serves to limit the axial displacement of the unlock button 112 toward the outside. It is understood that the outer side herein refers to the peripheral side of the support 113 away from the first accommodating cavity 1133, and the inner side refers to the space surrounded by the first accommodating cavity 1133.

When the unlock button 112 is released, the unlock button 112 moves outward in the axial direction by the elastic force of the unlock spring 117, and when the limit rib 1122 abuts against the limit surface 1156, the unlock button 112 stops moving outward in the axial direction. This ensures that the unlock button 112 is securely positioned in the rotation block 115, preventing the unlock button 112 from being disengaged from the rotation block 115.

It will be appreciated that a limit rib 1122 may be employed to axially limit the displacement of the release button 112. Of course, a plurality of limit ribs 1122 may also be used to axially limit the displacement of the release button 112. Specifically, the number of the limiting ribs 1122 is equal to the number of the positioning ribs 1121, the number of the limiting ribs 1122 is equal to the number of the limiting surfaces 1156, and the arrangement positions of the limiting ribs 1122 are equal to the arrangement positions of the limiting surfaces 1156. The limiting ribs 1122 may be connected to the positioning ribs 1121, and of course, the limiting ribs 1122 may have a distance from the positioning ribs 1121. Illustratively, the number of the limiting ribs 1122 is two, and the limiting ribs 1122 are connected to the positioning ribs 1121, and the included angle between the positioning ribs 1121 and the limiting ribs 1122 is 90 °.

It is understood that the unlocking spring 117 may be a compression spring. After the unlocking button 112 is unlocked by the unlocking spring 117, an operator can toggle the unlocking blade 111, so that the unlocking blade 111 is switched between the working position and the non-working position. Of course, the unlocking spring 117 may also be a torsion spring, and the torsion force of the unlocking spring 117 can make the rotating block 115 drive the unlocking blade 111 to rotate from the non-working position to the working position.
