Technical Field

[0001] This invention relates to the field of unlocking device technology, and more specifically to a computer key with an unlocking mechanism. Background Technology

[0002] In power equipment management and control systems and similar safety production management systems, many devices require interlocking control. Operation requires authorization via a computer key to unlock these devices, preventing unauthorized personnel from unlocking them and endangering equipment and personnel safety. Computer keys are widely used in the power industry. During operation, the computer key receives operation tickets from the anti-misoperation host, reads the ticket aloud, and then guides the operator to correctly unlock the device according to the instructions.

[0003] In computer keys, the unlocking mechanism is directly related to the lock. The form of the unlocking mechanism directly determines the form of the computer key. Unlocking mechanisms are mainly divided into double-lever unlocking mechanisms and single-lever unlocking mechanisms. However, there are many types of single-lever unlocking mechanisms on the market, but their integration and miniaturization are insufficient. Furthermore, they generate unnecessary power consumption during unlocking, requiring larger battery capacities and thus larger computer keys, hindering highly miniaturized and integrated designs. This creates inconvenience for management and for users in terms of carrying and operation. Summary of the Invention

Detailed Implementation

[0017] According to an embodiment of the present invention, an unlocking mechanism is provided, such as... Figure 1 As shown, the unlocking mechanism in this embodiment includes: an unlocking mechanism housing 30, an unlocking rod 10, an unlocking bushing 20, an unlocking base 80, a locking component 70, a central shaft 100, a spring 90, and an unlocking drive module 50.

[0018] like Figure 4 As shown, the unlocking mechanism housing 30 has a first cavity 31 and a second cavity 32. The first cavity 31 is connected to the second cavity 32 and the first cavity 31 is cylindrical. The second cavity 32 has positioning holes 33 on both sides that are perpendicular to and pass through the axis of the first cavity 31. The outer periphery of the first cavity 31 of the unlocking mechanism housing 30 has a cylindrical groove 34 and an end cap 36 is provided in the groove 34.

[0019] like Figure 2 As shown, the unlocking lever 10 includes an unlocking shaft 12 and an unlocking head 11. The unlocking head 11 is located at the head of the unlocking lever 10. Ears 15 are provided on opposite sides of the outer periphery of the unlocking head 11. The ears 15 are positioned opposite each other. Multiple notches 14 are provided on the unlocking head 11, and these notches 14 are adapted to fit the pins inside the lock cylinder. A positioning groove 13 is provided on the unlocking shaft 12, located on the side away from the unlocking head 11 and perpendicular to the axis of the unlocking shaft 12.

[0020] The unlocking shaft 12 is installed inside the first cavity 31. The unlocking head 11 extends from the first cavity 31 to the outside of the housing 30 and protrudes from the housing. The unlocking rod 10 is provided with a through hole 16 that penetrates the unlocking rod. The through hole 16 is a stepped cylindrical hole. The diameter of the cylindrical hole near the unlocking head is slightly smaller than the diameter of the cylindrical hole at the bottom of the unlocking rod.

[0021] like Figure 3 As shown, the unlocking sleeve 20 has a through hole 21 and locking notches 22 on both sides of its bottom. The locking notches 22 are positioned opposite each other and have a slightly flared opening. The outer periphery of the unlocking sleeve 20 has protruding ribs 23, which are also positioned opposite each other. The unlocking sleeve 20 is located on the outer periphery of the unlocking shaft 12, below the unlocking head 11. The ribs 23 are located on the outer top of the housing 30. When the unlocking pin is in the locked position, the protruding ribs 23 are aligned with the ear 15.

[0022] like Figure 6 and Figure 8As shown, the unlocking base 80 has an unlocking shaft mounting hole 85 and a locking hole 81 axially formed along the unlocking shaft 12. The unlocking base 80 also has an unlocking base fixing hole 82 and an unlocking shaft positioning hole 83 perpendicular to the unlocking rod 10. The unlocking shaft mounting hole 85 is stepped, with an unlocking shaft mounting hole step 84. The locking hole 81 is located on both sides of the unlocking shaft mounting hole 85 and is symmetrically arranged. The unlocking shaft 12 is inserted into the unlocking shaft mounting hole 85 on the unlocking base 80. The unlocking shaft positioning hole 83 and the positioning groove 13 are aligned. A positioning pin is driven into the unlocking shaft positioning hole 83 and the positioning groove 13. The unlocking base 80 is fixed in the second cavity 32 by the positioning pin passing through the unlocking base fixing hole 82 and the positioning hole 33 on the housing. The positioning pin restricts the circumferential rotation of the unlocking shaft 12 relative to the unlocking base 80, and the unlocking shaft mounting hole step 84 restricts the axial position of the unlocking shaft 12 relative to the unlocking base 80.

[0023] like Figure 5 As shown, the locking component 70 includes an unlocking pin 71 and an unlocking pin seat 72. The unlocking pin seat 72 has a U-shaped groove 73 along the axial direction of the unlocking shaft 12. There are two unlocking pins 71. The unlocking pins 71 are inserted into the locking hole 81 and move along the locking hole 81. The head of the unlocking pin 71 is hemispherical and has a smooth surface to prevent the unlocking pin 71 from getting stuck during the movement of the locking hole 81. The locking hole 81 restricts the rotation of the unlocking pin 71. When the unlocking pin 71 moves upward to the insertion locking notch 22, the unlocking sleeve 20 is restricted from circumferential rotation by the unlocking pin 71, and the unlocking mechanism is in the locked position. When the unlocking pin 71 moves downward out of the locking notch 22, the unlocking sleeve 20 can rotate along the unlocking shaft 12, and the unlocking mechanism is in the unlocked position.

[0024] like Figure 7 As shown, the central shaft 100 is a stepped shaft with two steps. The central shaft 100 passes through the through hole 16 of the unlocking rod, with the first shaft segment 101 passing through the end near the unlocking head 11 and the second shaft segment 103 passing through the end of the unlocking rod through hole 16 away from the unlocking head 11. The step 102 between the first shaft segment 101 and the second shaft segment 103 cooperates with the step in the unlocking rod through hole 16 to restrict the central shaft 100 from moving out of the unlocking rod. The central shaft 100 passes downward through the unlocking shaft mounting hole 85 and the unlocking pin seat U-shaped groove 73, wherein the step 104 below the second shaft segment 103 is larger than the U-shaped groove 73.

[0025] like Figure 1 As shown, the spring 90 is installed on the outer periphery of the second shaft section 103 of the central shaft. The upper end of the spring abuts against the step 102 between the first shaft section and the second shaft section, and the lower end of the spring abuts against the step 84 of the unlocking shaft mounting hole.

[0026] Unlocking drive module 50 is used to apply a pulling force to locking component 70 to switch unlocking pin 71 from the locked position to the unlocked position.

[0027] like Figure 9 As shown, the unlocking drive module 50 includes a motor 51, a gear 54, and a rack 52. The drive motor 51 is fixedly mounted on a motor support 53, which is connected to the unlocking mechanism housing 30. The motor shaft is connected to the gear 54, which meshes with the rack 52. The rack 52 is connected to the locking component 70, which can be moved between the locking position where the unlocking pin 71 is inserted into the locking notch 22 and the unlocking position where it is disengaged from the locking notch 22, driven by the rack 52.

[0028] like Figure 1 As shown, the code reading component 35 is installed in the groove 34 of the unlocking mechanism housing for reading the lock code value, and the groove waterproof end cap 36 is installed on the unlocking mechanism housing.

[0029] The unlocking mechanism also includes two conductive electrode components 40. The two conductive electrode components are respectively disposed on both sides of the housing 30 and extend through the housing of the unlocking mechanism. The conductive electrode components are used to supply power to the electrical lock.

[0030] like Figure 1 and Figure 7 As shown, the unlocking mechanism also includes a detection mechanism, which includes a detection component 60. The detection component 60 is mounted on the motor support 53 and located at the bottom of the unlocking mechanism, directly below the moving direction of the central shaft 100. The component to be detected 105 is mounted at the tail of the central shaft 100.

[0031] Under normal conditions, the unlocking pin 71 of the locking component 70 is inserted into the locking notches 22 on both sides of the unlocking sleeve 20, restricting the rotation of the unlocking sleeve 20. The protruding rib 23 of the unlocking sleeve 20 is aligned with the ear 15 of the unlocking head 11 and is in the same plane. When the unlocking mechanism unlocks the five-proof lock, the unlocking head 11 and the protruding rib 23 of the unlocking sleeve 20 are inserted into the lock hole. The pin in the lock hole pushes against the central shaft 100 and moves downward, compressing the spring 90. The detected component 105 moves downward with the central shaft and approaches the detection component 60. The detection component 60 detects... Upon reaching the tested component 105, the computer key supplies power to the code reader 35. The code reader 35, housed within the housing, operates, reading the lock's code value. When the correct code value is read, the computer key controls the unlocking drive module 50 to operate. The rotation of the motor 51 drives the gear 54, causing the rack 52 to move downwards. The rack 52 then causes the locking component 70 to move downwards, disengaging the unlocking pin 71 from the locking notch 22. The unlocking sleeve 20 can rotate along the unlocking shaft 12. Turning the computer key allows for lock cylinder unlocking. The unlocking sleeve 20, constrained by the lock cylinder, rotates relative to the unlocking mechanism. Figure 9As shown, the lock is unlocked. After the unlocking operation is completed, when the unlocking head 11 and unlocking sleeve 20 are pulled out of the lock cylinder, the unlocking sleeve 20 returns to its initial position. The protruding rib 23 of the unlocking sleeve 20 is aligned with the ear 15 of the unlocking head 11. The central shaft 100 leaves the pin in the lock hole. Under the reset action of the spring 90, the central shaft 100 moves towards the unlocking head 11. Since the size of the step 104 at the tail of the central shaft is larger than the size of the U-shaped groove 73 on the unlocking pin seat 72, the step 104 at the tail of the central shaft drives the locking component 70 together with the unlocking pin 71 to move towards the unlocking head 11. The unlocking pin 71 is inserted into the locking notch 22 of the unlocking sleeve 20, and the computer key is in an unlockable state.

[0032] See Figures 1 to 11 As shown, according to another aspect of the present invention, a computer key is provided, the computer key including an unlocking mechanism, the unlocking mechanism being the aforementioned unlocking mechanism.

[0033] As can be seen from the above structure, in this embodiment, the code-reading module only starts working when the computer key is inserted into the lock hole. In contrast, with conventional computer keys, the code-reading module starts working as soon as the work permit is received, resulting in a long waiting time before the lock unlocks. This embodiment avoids the energy waste caused by the code-reading module continuously consuming power, thus reducing battery size. Furthermore, the computer key's reset process is achieved through the self-resetting action of a spring, further avoiding power waste. This allows for a significant reduction in the size of the highly integrated unlocking mechanism and the computer key itself, making it easier for users to carry and operate.
