Description

Technical Field

[0001] This application relates to the field of lock technology, and in particular to an unlocking mechanism. Background Technology

[0002] In related technologies, computer keys are an important component in the field of power safety and security, and the unlocking mechanism is an indispensable part of computer keys, which is directly related to the unlocking process of locks. The unlocking mechanism involves an authorization mechanism, and the smoothness of the authorization mechanism directly affects the smoothness of unlocking, and its reliability directly determines the success of unlocking or locking.

[0003] Currently, there are two types of authorized unlocking mechanisms on the market: 1. Electromagnetic components directly participate in the mechanism's operation. The moving parts of the electromagnetic components need to be kept smooth for them to function properly, and the electromagnetic components are prone to damage, leading to jamming and affecting normal unlocking; 2. Electromagnetic components indirectly participate in the mechanism's operation through other parts, such as patent CN107178253B. In this structure, the cylindrical pin experiences significant resistance during operation, which may cause jamming. To avoid this, the electromagnetic components must increase power consumption and generate greater thrust, resulting in high power consumption for the computer key. Under the same battery power, this will inevitably affect the number of unlocking attempts and the user experience of the computer key. Utility Model Content

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes an unlocking mechanism that has low power consumption and reliable performance.

[0005] The unlocking mechanism according to an embodiment of the present invention includes: a housing, a locking shaft, an unlocking rod assembly, an authorization mechanism, and an unlocking module component. The housing has a first receiving cavity and a through hole communicating with the first receiving cavity. The locking shaft is inserted into the through hole and is hollow. The locking shaft includes a first head and a first main body connected to each other. The first main body is located in the first receiving cavity and has a locking groove on its inner sidewall. The first head protrudes from the through hole. One end of the unlocking rod assembly is inserted into the locking shaft and at least one end of the locking shaft is hollow. The unlocking rod assembly includes a second head and a second main body connected to each other. The second head protrudes from the end of the first head away from the housing. The second main body is located in the first receiving cavity. The accommodating cavity has a sliding hole with a corresponding locking groove. The sliding hole includes a locking position near the locking groove and an unlocking position away from the locking groove. The authorization mechanism includes a fixing part, a spindle, and a rolling element. The fixing part has an electromagnetic element inside and is fixed to the unlocking rod assembly. One end of the spindle is connected to the fixing part, and the other end is inserted into the unlocking rod assembly. The rolling element is located outside the spindle and accommodated in the sliding hole. The fixing part can drive the spindle to extend and retract along its own axis so that the rolling element can move between the locking position and the unlocking position in the sliding hole to lock or release the locking shaft. The unlocking module component is used to send a signal to the authorization mechanism so that the electromagnetic element drives the spindle to extend and retract so that it can move the rolling element.

[0006] The unlocking mechanism according to the present invention has at least the following beneficial effects: The unlocking mechanism includes a housing, a locking shaft, an unlocking rod assembly, an authorization mechanism, and an unlocking module component. The first main body of the locking shaft is inserted into the first receiving cavity of the housing, with the first head of the locking shaft protruding from the through hole of the housing. The second main body of the unlocking rod assembly is inserted into the locking shaft, with the second head of the unlocking rod assembly protruding from the first head of the locking shaft. The inner sidewall of the first main body is provided with a locking groove, and the second main body is correspondingly provided with a through sliding hole. The sliding hole has a locking position near the locking groove and an unlocking position away from the locking groove. The fixing part of the authorization mechanism is fixed to the unlocking rod assembly. The spindle of the authorization mechanism is telescopically connected to the fixing part and inserted into the unlocking rod assembly. A rolling element is located outside the spindle and accommodated in the sliding hole of the unlocking rod assembly. In the initial state, the rolling element is located in the locking position of the sliding hole and abuts against the outside of the spindle and the locking groove of the locking shaft, thereby locking the locking groove. When the unlocking module component sends a signal to the authorization mechanism to drive the spindle to retract, the fixing part of the authorization mechanism rotates. The locking mechanism, including the locking rod assembly, can pull the rolling element out of the locking groove of the locking shaft and move it from the locked position to the unlocked position within the sliding hole of the unlocking rod assembly. This allows for smooth unlocking of the locking shaft and relative rotation between the unlocking rod assembly and the locking shaft. After the authorization mechanism is powered off, the unlocking rod assembly is rotated back to its original position. At this point, the sliding hole aligns with the locking groove, and the spindle, having lost its electromagnetic force, extends from the fixed part. During this extension, it holds the rolling element in place within the sliding hole, causing it to move from the unlocked position to the locked position, thus re-locking the locking shaft. Since the unlocking process relies on the rotation of the unlocking rod assembly to move the rolling element out of the locking groove, the spindle does not need to drive any load along the axial direction during authorization, requiring no additional power consumption. Therefore, the power consumption of the electromagnetic components can be minimized, increasing the number of unlocking cycles under the same battery power, thus improving the user experience. Furthermore, after the spindle retracts, the rotation of the unlocking rod assembly can pull the rolling element out of the locking groove, reducing jamming and improving the smoothness of unlocking.

[0007] According to some embodiments of the present invention, a clearance position is provided at the end of the mandrel away from the fixed part. When the mandrel moves towards the fixed part, the clearance position is aligned with the unlocking position. The rolling element can roll under the rotation of the unlocking rod assembly to slide out of the locking groove and move from the locking position to the unlocking position.

[0008] According to some embodiments of the present invention, a step is provided at one end of the mandrel away from the fixed part. The step includes a supporting part and a journal disposed sequentially away from the fixed part. The outer diameter of the journal is smaller than the outer diameter of the supporting part, and the outer periphery of the journal is smaller than the outer diameter of the supporting part to form a clearance position. When the sliding hole is aligned with the locking groove and the mandrel moves away from the fixed part, the supporting part can support the rolling element to roll, so that the rolling element moves from the unlocked position to the locked position. According to some embodiments of this utility model, the rolling element is a steel ball.

[0009] According to some embodiments of the present invention, locking grooves are provided on opposite sides of the inner sidewall of the first main body, sliding holes are provided on opposite sides of the second main body, and steel balls are arranged in pairs.

[0010] According to some embodiments of the present invention, the unlocking rod assembly includes a base and an unlocking rod. The base is disposed in the first receiving cavity and has a sliding hole. One end of the unlocking rod is fixedly connected to the base, and the other end protrudes from the first head.

[0011] According to some embodiments of the present invention, a locking member is also included. The outer periphery of the fixing part is provided with an annular groove, and the base is provided with a through connecting hole. The locking member is locked to the annular groove through the connecting hole.

[0012] According to some embodiments of the present invention, the unlocking module component includes a code reading module, which is located in the first receiving cavity near the first head.

[0013] According to some embodiments of this utility model, it also includes a magnetic component and a detection component, which are respectively disposed inside the housing and on the locking shaft. The detection component is used to detect the relative rotation angle of the magnetic component.

[0014] According to some embodiments of the present invention, the second head is provided with a second notch, and the first head is provided with a first notch. When the rolling element is in the locked position, the first notch and the second notch are aligned. Attached Figure Description

[0022] The following is for reference. Figures 1 to 8 This invention describes an unlocking mechanism according to an embodiment of the present invention.

[0023] like Figures 1 to 5 As shown, the unlocking mechanism according to an embodiment of the present invention includes: a housing 100, a locking shaft 200, an unlocking rod assembly 300, an authorization mechanism 400, and an unlocking module component. The housing 100 has a first receiving cavity 101 and a through hole 102 communicating with the first receiving cavity 101. The locking shaft 200 is inserted into the through hole 102 and is hollow. The locking shaft 200 includes a first head 210 and a first body 220 connected to each other. The first body 220 is located in the first receiving cavity 101 and has a locking groove 221 on its inner sidewall. The first head 210 protrudes from the through hole 102. One end of the unlocking rod assembly 300 is inserted into the locking shaft 200 and at least one end of the locking shaft 200 is hollow. The unlocking rod assembly 300 includes a second head and a second body connected to each other. The second head protrudes from the end of the first head 210 away from the housing 100. The second body is located in the first receiving cavity 101 and has a corresponding locking groove 221. The locking groove 221 has a sliding hole 311, which includes a locking position 3111 near the locking groove 221 and an unlocking position 3112 away from the locking groove 221. The authorization mechanism 400 includes a fixing part 410, a spindle 420, and a rolling element 430. The fixing part 410 is equipped with an electromagnetic element and is fixed to the unlocking rod assembly 300. One end of the spindle 420 is connected to the fixing part 410, and the other end is inserted into the unlocking rod assembly 300. The rolling element 430 is located outside the spindle 420 and is accommodated in the sliding hole 311. The fixing part 410 can drive the spindle 420 to extend and retract along its own axis so that the rolling element 430 can move between the locking position 3111 and the unlocking position 3112 in the sliding hole 311 to lock or release the locking shaft 200. The unlocking module component is used to send a signal to the authorization mechanism 400 so that the electromagnetic element drives the spindle 420 to extend and retract so that the rolling element 430 can move.

[0024] Understandably, this unlocking mechanism includes: a housing 100, a locking shaft 200, an unlocking rod assembly 300, an authorization mechanism 400, and an unlocking module component. The first main body 220 of the locking shaft 200 is inserted into the first receiving cavity 101 of the housing 100, and the first head 210 of the locking shaft 200 protrudes from the through hole 102 of the housing 100. The second main body of the unlocking rod assembly 300 is inserted into the locking shaft 200, and the second head of the unlocking rod assembly 300 protrudes from the first head 210 of the locking shaft 200. The inner sidewall of the first main body 220 is provided with a locking groove 221, and the second main body is correspondingly provided with a through sliding hole 311. The sliding hole 311 is provided with a locking position near the locking groove 221. 3111 and unlocking position 3112 away from locking groove 221, the fixing part 410 of the authorization mechanism 400 is fixed to the unlocking rod assembly 300, the spindle 420 of the authorization mechanism 400 is telescopically connected to the fixing part 410 and inserted into the unlocking rod assembly 300, the rolling element 430 is located outside the spindle 420 and accommodated in the sliding hole 311 of the unlocking rod assembly 300; in the initial state, the rolling element 430 is located in the locking position 3111 of the sliding hole 311 and abuts against the outside of the spindle 420 and the locking groove 221 of the locking shaft 200, thereby locking the locking groove 221. When the unlocking module component sends a signal to the authorization mechanism 400 to drive the spindle 420 to retract, the authorization mechanism 400 is then rotated. The fixing part 410 and the unlocking rod assembly 300 of the mechanism 400 can bring the rolling element 430 out of the locking groove 221 of the locking shaft 200, and make the rolling element 430 move from the locking position 3111 to the unlocking position 3112 in the sliding hole 311 of the unlocking rod assembly 300, thereby successfully unlocking the locking shaft 200, and then realizing the relative rotation of the unlocking rod assembly 300 and the locking shaft 200. After the authorization mechanism 400 is de-energized, the unlocking rod assembly 300 is rotated to its original position. At this time, the sliding hole 311 and the locking groove 221 are aligned. The spindle 420 can extend out of the fixing part 410 due to the loss of electromagnetic force, and during the extension process, it resists the rolling element 430 in the sliding hole 311. The movement causes the rolling element 430 to move from the unlocking position 3112 to the locking position 3111, thus re-locking the locking shaft 200. During the unlocking process, the rolling element 430 unlocks the locking shaft 200 by rotating the unlocking rod assembly 300 and driving it out of the locking groove 221. Therefore, during the authorization process, the spindle 420 does not need to drive any load to move axially, and there is no need for additional power consumption. Thus, the power consumption of the electromagnetic component can be minimized, thereby increasing the number of unlocking cycles under the same battery power supply, thereby improving the user experience. Furthermore, after the spindle 420 retracts, it can bring the rolling element 430 out of the locking groove 221 during the rotation of the unlocking rod assembly 300, reducing jamming and improving the smoothness of unlocking.

[0025] Understandably, the end of the spindle 420 away from the fixed part 410 is provided with a clearance position 4221. When the spindle 420 moves toward the fixed part 410, the clearance position 4221 aligns with the unlocking position 3112, and the rolling element 430 can roll under the rotation of the unlocking rod assembly 300 to slide out of the locking groove 221 and move from the locking position 3111 to the unlocking position 3112. For example, as Figure 4 and Figure 5 As shown, in this embodiment, when the spindle 420 retracts into the fixing part 410 under the electromagnetic action of the electromagnetic element, the clearance position 4221 of the end of the spindle 420 away from the fixing part 410 is aligned with the sliding hole 311 of the unlocking rod assembly 300, making room for the unlocking position 3112 of the sliding hole 311. This allows the rolling element 430 to have space to roll in the sliding hole 311, thereby enabling the unlocking rod assembly 300 to rotate relative to the locking shaft 200 and bring the rolling element 430 out of the locking groove 221 of the locking shaft 200, thus achieving unlocking.

[0026] It is understood that the end of the spindle 420 away from the fixed part 410 is provided with a step. The step includes a supporting part 421 and a journal 422 arranged sequentially away from the fixed part 410. The outer diameter of the journal 422 is smaller than the outer diameter of the supporting part 421, and the outer region smaller than the outer diameter of the supporting part 421 forms a clearance position 4221. When the sliding hole 311 is aligned with the locking groove 221 and the spindle 420 moves away from the fixed part 410, the supporting part 421 can support the rolling element 430 to roll, so that the rolling element 430 moves from the unlocked position 3112 to the locked position 3111. Figure 1-5 In this embodiment, the end of the spindle 420 away from the fixed part 410 is provided with a supporting part 421 and a journal 422 with successively decreasing outer diameters. In the initial state, the rolling element 430 abuts between the supporting part 421 and the locking groove 221 of the locking shaft 200. When the electromagnetic element in the authorization mechanism 400 drives the spindle 420 to retract, the shaft diameter moves closer to the fixed part 410. Thus, the clearance position 4221 formed by the area of ​​the outer periphery of the shaft diameter which is smaller than the outer diameter of the supporting part 421 provides space for the rolling element 430 to move, so that the rolling element 430 can roll from the locked position 3111 to the unlocked position 3112 under the drive of the unlocking rod assembly 300, and realize the unlocking of the locking shaft 200.

[0027] It is understood that in this embodiment, the rolling element 430 is a steel ball. In other embodiments, the rolling element 430 may also be ellipsoidal. When the abutting part 421 is conical, the ellipsoidal rolling element 430 can be abutted into the locking groove 221 of the locking shaft 200 by the conical surface.

[0028] It is understandable that the locking groove 221 is located on opposite sides of the inner wall of the first main body 220, the sliding hole 311 is located on opposite sides of the second main body, and the steel balls are arranged in pairs. Figure 4-5 The locking groove 221 is provided on opposite sides of the inner wall of the first main body 220, and the sliding hole 311 is also correspondingly opened on the second main body. The steel balls are also arranged in pairs, thereby improving the effectiveness of locking.

[0029] It is understood that the unlocking lever assembly 300 includes a base 310 and an unlocking lever 320. The base 310 is disposed in the first receiving cavity 101 and has a sliding hole 311. One end of the unlocking lever 320 is fixedly connected to the base 310, and the other end protrudes from the first head 210. Figure 4-5 In this embodiment, the unlocking rod assembly 300 includes a base 310 with a sliding hole 311 and an unlocking rod 320 connected to the base 310. One end of the unlocking rod 320 protrudes from the first head 210, which facilitates assembly and fixation.

[0030] Understandably, it also includes a locking element. The fixing part 410 has an annular groove 411 on its outer periphery, and the base 310 has a through connecting hole. The locking element is locked into the annular groove 411 through the connecting hole. For example, as... Figure 4-5 As shown, in this embodiment, the base 310 and the fixing part 410 are locked by the locking member, thereby fixing the authorization mechanism 400 and the unlocking rod assembly 300.

[0031] It is understood that the unlocking module component includes a code reading module 510, which is located within the first receiving cavity 101 near the first head 210. For example, as Figure 1 In this embodiment, when the unlocking mechanism unlocks the lock, the code reading module 510 located in the first receiving cavity 101 near the first head 210 is used to read the code value of the lock.

[0032] It should be understood that, such as Figure 1-8 The unlocking module also includes electrode shafts 520 located on both sides of the housing 100 for supplying power to a specific lock.

[0033] It should be understood that, such as Figure 1-8 The unlocking module also includes a wireless communication component 530 located on the top of the housing 100. The wireless communication component 530 is an infrared communication window used for communication detection of the lock-related sensing elements.

[0034] Understandably, it also includes magnetic components and detection components. The magnetic components and detection components are respectively located inside the housing (below the code reading module) and on the locking shaft. The detection components are used to detect the relative rotation angle of the magnetic components.

[0035] Once all components of the unlocking module have received the correct data, the system supplies power to the electromagnetic components before the unlocking action can be performed.

[0036] It is understandable that the second head has a second notch 321, and the first head 210 has a first notch 211. When the rolling element 430 is in the locking position 3111, the first notch 211 and the second notch 321 are aligned. Figure 6-7 When the rolling element 430 is in the locking position 3111, that is, between the abutment part 421 of the spindle 420 of the authorization mechanism 400 and the locking groove 221 of the locking shaft 200, the first notch 211 of the first head 210 and the second notch 321 of the second head are aligned to prevent misalignment, thereby aligning them to facilitate the insertion of the lock.

[0037] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
