Technical Field
[0001] This invention belongs to the field of computer lock technology, and specifically refers to a driving structure for a computer lock. Background Technology
[0002] A laptop lock, also known as a notebook anti-theft lock, is a lock specifically designed for portable electronic devices such as laptops and tablets. One side of the lock body has a keyhole into which the electronic device can be inserted to lock or unlock. The lock tongue, controlled by a mechanical structure, can open and close to engage with the inner wall of the keyhole or be pulled out of the keyhole. The other side of the lock body typically has a high-strength cable or similar object to secure the laptop lock in a specific location / area.
[0003] Currently, electronic device locks on the market typically come in three types: standard locks, nano locks, and wedge locks, each with different length and width dimensions (e.g., 3*5, 2.5*6, 3*7). Existing computer locks have a fixed bolt travel, meaning that a single type of lock can only fit locks of a specific length. When a user owns multiple electronic devices with different lock sizes, they need to purchase a separate lock for each device / lock size. This not only increases the user's operating costs but also causes inconvenience in carrying and managing multiple locks. Summary of the Invention
[0004] The main objective of this invention is to provide a drive structure for a computer lock, which solves the problems existing in the prior art, enabling the computer lock to adapt to multiple sizes of keyholes and meet the needs of adjustable, one-to-many usage.
[0005] To achieve the above objectives, the solution of the present invention is: A drive structure for a computer lock includes a lock housing, a pair of bolts, a sliding member, a motor, and an adjusting member. The bolts are closably mounted on the surface of the lock housing. The sliding member is slidably fitted within the lock housing, and one end of the sliding member has a pin that movably passes between the bolts, the pin being used to control the opening angle of the bolts. The motor is mounted within the lock housing and is drively connected to the other end of the sliding member. The adjusting member is slidably fitted within the lock housing and located on the sliding path of the sliding member. The sliding process of the adjusting member includes at least two states that stop the sliding member and shut down the motor.
[0006] The surface of the slider is provided with at least two steps, and a conductive element is installed on the adjusting element. The conductive element is aligned with one of the steps as the adjusting element slides, and generates a control signal when it contacts the corresponding step.
[0007] Preferably, a circuit board is provided inside the lock housing. The circuit board is electrically connected to the motor and is configured to receive the current on / off signal of the conductive element. When the circuit corresponding to the conductive element is turned on, the circuit board controls the motor to stop working.
[0008] Preferably, the entire lock housing or at least a portion thereof is made of a conductive material and is electrically connected to the circuit board; one end of the conductive element is provided with a contact spring arm, the two ends of the contact spring arm are respectively configured as a first contact and a second contact, and the other end of the conductive element is electrically connected to the circuit board; the first contact and the second contact are respectively disposed opposite to the step of the sliding element and the inner wall of the lock housing; when the first contact contacts the step, the step pushes the contact spring arm to deform so that the second contact contacts the inner wall of the lock housing.
[0009] The surface of the adjusting component is provided with a lever, and the lock housing is provided with a guide hole for the lever to slide and engage, with the lever extending out of the outside of the guide hole.
[0010] The lock housing is provided with a first guide groove for the adjusting member to slide and engage, and the side wall of the first guide groove is provided with a stop notch; the side of the adjusting member is provided with a stop spring arm, and the stop spring arm is provided with a stop protrusion that elastically engages with the side wall of the first guide groove and its stop notch.
[0011] The motor and the sliding member are coaxially arranged. The output end of the motor is provided with a screw, which is threaded into a screw hole at the other end of the sliding member. The lock housing is provided with a second guide groove for sliding engagement of the sliding member. The side of the sliding member is configured as a plane that slides into the side wall of the second guide groove.
[0012] The surface of the lock housing is provided with a fixing seat, the end of the lock tongue is pivotally fitted in the fixing seat, and the pin is movably inserted through the fixing seat and inserted between the lock tongues.
[0013] Preferably, a rubber ring is fitted on the surface of the latch, the rubber ring being used to provide elastic force to return the latch to the closed state.
[0014] The opposite surface of the latch is provided with several beveled protrusions for the end of the pin to move and engage. When the pin pushes against different protrusions, the opening angle of the latch is different.
[0015] After adopting the above technical solution, the present invention has the following technical effects: This invention, by incorporating an adjusting component, allows for manual adjustment of the sliding stroke of the sliding component to accommodate different keyhole sizes. This, in turn, alters the depth of the bolt insertion into the bolt, thereby adjusting the bolt opening angle. This enables a single computer lock to simultaneously accommodate multiple keyhole sizes, meeting adjustable, one-to-many usage requirements and reducing user costs. Furthermore, while stopping the sliding component, the adjusting component can also be designed to send a corresponding signal to shut down the motor, preventing it from continuing to rotate after the sliding component stops. This avoids motor overload damage and improves the stability and lifespan of the drive structure. Attached Figure Description

Detailed Implementation
[0030] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.
[0031] refer to Figures 1 to 13 As shown, the present invention discloses a drive structure for a computer lock, including a lock housing 10, a pair of lock tongues 20, a sliding member 30, a motor 40, and an adjusting member 50; The latch 20 is detachably mounted on the surface of the lock housing 10; The sliding member 30 is slidably fitted inside the lock housing 10. One end of the sliding member 30 is provided with a pin 31 that is movably inserted between the bolts 20. The pin 31 is used to control the opening angle of the bolts 20. That is, the opening angle of the bolts 20 is different depending on the insertion depth of the pin 31. The motor 40 is installed inside the lock housing 10 and is connected to the other end of the sliding member 30 for transmission. The adjusting member 50 is slidably fitted inside the lock housing 10 and located on the sliding path of the sliding member 30; the sliding process of the adjusting member 50 is provided with at least two states that stop the sliding member 30 and shut down the motor 40.
[0032] Through the above solution, the present invention, by setting the adjusting component 50, can adjust the sliding stroke of the sliding component 30 according to the needs of different keyhole sizes by manually operating the adjusting component 50, thereby changing the depth of the bolt 31 inserted into the bolt 20, and realizing the adjustment of the opening angle of the bolt 20. This allows a single computer lock to simultaneously adapt to multiple keyhole sizes, meeting the needs of adjustable, one-to-many usage and reducing user operating costs. Furthermore, while stopping the sliding component 30, the adjusting component 50 can be designed to send a corresponding signal to shut down the motor 40, preventing the motor 40 from continuing to rotate after the sliding component 30 stops, avoiding motor overload damage, and improving the stability and service life of the drive structure.
[0033] The following illustrates specific embodiments of the present invention.
[0034] The surface of the aforementioned sliding member 30 is provided with at least two steps 32. A conductive member 60 is mounted on the adjusting member 50. As the adjusting member 50 slides, the conductive member 60 aligns with one of the steps 32 and generates a control signal when it contacts the corresponding step 32. In this embodiment, the sliding direction of the aforementioned sliding member 30 is set to the length direction of the lock housing 10. The steps 32 are arranged in a stepped manner along the width direction of the lock housing 10 on the surface of the sliding member 30. The latch 20 is provided on the end face of the lock housing 10. The sliding direction of the adjusting member 50 is set to the width direction of the lock housing 10, that is, perpendicular to the sliding direction of the sliding member 30. This allows the conductive member 60 mounted on the adjusting member 50 to align with the steps 32 at different positions when it moves along the width direction of the lock housing 10, thereby determining that the sliding member 30 needs to slide different distances to contact the conductive member 60.
[0035] Furthermore, a circuit board 70 is provided inside the lock housing 10. The circuit board 70 is electrically connected to the motor 40 and is configured to receive the current on / off signal of the conductive element 60. When the circuit corresponding to the conductive element 60 is turned on, the circuit board 70 controls the motor 40 to stop working.
[0036] Secondly, the entire lock housing 10, or at least a part thereof, is made of conductive material and is electrically connected to the circuit board 70 (the conductive part is in direct contact or connected by a wire). One end of the conductive element 60 is provided with a contact spring arm 61, and the two ends of the contact spring arm 61 are respectively set as a first contact 62 and a second contact 63. The other end of the conductive element 60 is electrically connected to the circuit board 70 through a wire to ensure that the conductive element 60 and the circuit board 70 are always electrically connected and not disconnected during the sliding of the adjusting element 50. The first contact 62 and the second contact 63 are respectively arranged opposite to the step 32 of the sliding element 30 and the inner wall of the lock housing 10. When the first contact 62 contacts the step 32, the step 32 pushes the contact spring arm 61 to deform so that the second contact 63 contacts the inner wall of the lock housing 10, thereby realizing the conduction of the circuit corresponding to the conductive element 60. In this embodiment, the circuit board 70 is provided with several physical buttons for inputting a password. When the user inputs the correct password, the circuit board 70 controls the motor 40 to work according to a preset program so that the pin 31 of the sliding member 30 disengages from the latch 20, thereby unlocking the door. When the user presses the lock button, the circuit board 70 controls the motor 40 to work according to a preset program so that the pin 31 of the sliding member 30 inserts into the latch 20. The conductive member 60 is formed by folding a conductive metal. The lock shell 10 is electrically connected to the negative terminal of the circuit board 70, and the conductive member 60 is electrically connected to the positive terminal of the circuit board 70. A battery 80 electrically connected to the circuit board 70 is provided inside the lock shell 10. The battery 80 is designed to be replaceable or rechargeable.
[0037] The surface of the aforementioned adjusting member 50 is provided with a lever 51, and the lock housing 10 is provided with a guide hole 111 for the lever 51 to slide and engage. The lever 51 extends out of the outside of the guide hole 111 for user operation. In this embodiment, an indicator light 71 located on the side of the guide hole 111 is provided on the circuit board 70 installed inside the lock housing 10. When the lever 51 moves to a certain position, the indicator light 71 at the corresponding position is lit, thereby indicating the current status of the lock.
[0038] The lock housing 10 is provided with a first guide groove 112 for sliding engagement of the adjusting member 50. The side wall of the first guide groove 112 is provided with a stop notch 113. The side of the adjusting member 50 is provided with a stop spring arm 52. The stop spring arm 52 is provided with a stop protrusion 53 that elastically engages with the side wall of the first guide groove 112 and its stop notch 113. Therefore, by designing the first guide groove 112, the adjustment component 50 can be ensured to slide along the path designed in the product to ensure functional stability. At the same time, the cooperation between the stop notch 113 and the stop protrusion 53 can ensure that the adjustment component 50 is kept in the corresponding position after the user operates it and will not slide randomly, thus improving the operation feel and positioning accuracy of the adjustment process. The stop protrusion 53 will slide elastically along the side wall of the first guide groove 112 as the adjustment component 50 slides. When it slides to a certain stop notch 113, the stop protrusion 53 will be embedded into the corresponding stop notch under the elastic force of the stop spring arm 52 and produce a clear "click" feedback, which makes it convenient for the user to intuitively perceive that the gear shift is completed.
[0039] The motor 40 and the sliding member 30 are coaxially arranged. The output end of the motor 40 is provided with a screw 41, which is threaded into a screw hole 33 at the other end of the sliding member 30. Thus, the torque output by the motor 40 can be converted into linear motion of the sliding member 30, thereby driving the sliding member 30 to move different distances, so that the pin 31 can be inserted into the latch 20 at different depths.
[0040] Furthermore, the lock housing 10 is provided with a second guide groove 114 for sliding engagement of the slider 30, and the side of the slider 30 (the surface not provided with the step 32) is provided as a plane 34 that slides into engagement with the side wall of the second guide groove 114.
[0041] The surface of the lock housing 10 is provided with a fixing seat 90, the end of the lock tongue 20 is pivotally fitted in the fixing seat 90, and the pin 31 is movably inserted through the fixing seat 90 and inserted between the lock tongues 20.
[0042] Furthermore, a rubber ring 100 is fitted onto the surface of the latch 20, providing elastic force to return the latch 20 to the closed state. Thus, when the computer lock is in the locked state (latch open), the rubber ring 100 is under tension, accumulating elastic potential energy. When the pin 31 disengages from the latch 20, the rubber ring 100 allows the latch 20 to close, reducing resistance when the user pulls out the lock and improving the user experience. In this embodiment, at least a portion of the rubber ring 100 is fixedly connected to the surface of the mounting base 90 to prevent displacement.
[0043] The opposing surfaces of the aforementioned latch 20 are provided with a plurality of beveled protrusions 21 for movable engagement with the end of the pin 31. The number of protrusions 21 is the same as the number of states provided by the adjusting member 50. The opening angle of the latch 20 is different when the pin 31 pushes against different protrusions 21. The protrusions 21 may be staggered on two latches 20.
[0044] To facilitate the disassembly and assembly of components, the lock housing 10 is designed to include a detachably connected upper lock housing 11 and a lower lock housing 12. The upper lock housing 11 has corresponding groove structures inside for each component to meet the requirements of positioning, installation, and movement guidance.
[0045] See Figures 5 to 13 In this embodiment, three steps 32 are designed on the surface of the slider 30, and the corresponding working principle is as follows: (1) When the adjusting part 50 is moved to the first position, the lock is in the first state. After the user enters the password, the motor 40 rotates and the sliding part 30 is pushed out. The first contact of the conductive part 60 on the adjusting part 50 contacts the first step 32, which connects the circuit. The motor 40 stops rotating and the sliding part 30 stops moving. At this time, the opening angle of the lock tongue 20 can lock the 3*5 lock hole.
[0046] (2) When the adjusting part 50 is moved to the second position, the lock is in the second state. After the user enters the password, the motor 40 rotates and the sliding part 30 is pushed out. The first contact of the conductive part 60 on the adjusting part 50 contacts the step 32 of the second level, and the circuit is connected. The motor 40 stops rotating and the sliding part 30 stops moving. At this time, the opening angle of the lock tongue 20 can lock the 2.5*6 lock hole.
[0047] (3) When the adjusting piece 50 is moved to the third position, the lock is in the third state. After the user enters the password, the motor 40 rotates and the sliding piece 30 is pushed out. The first contact of the conductive piece 60 on the adjusting piece 50 contacts the third step 32, which connects the circuit. The motor 40 stops rotating and the sliding piece 30 stops moving. At this time, the opening angle of the lock tongue 20 can lock the 3*7 lock hole.
[0048] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
