Description

Technical Field

[0001] This utility model relates to the field of security equipment technology, specifically to an electronic lock. Background Technology

[0002] Electronic locks are widely used in homes, offices, hotels, and other places due to their convenient operation and high security. Existing electronic locks typically use a motor to drive a locking rod directly for locking or unlocking. However, this direct transmission method has the following drawbacks: First, the high rigidity during transmission makes the locking rod prone to jamming when the door is subjected to external impact or slight deformation, potentially damaging the motor or transmission components. Second, the locking stability of the locking rod depends on the positioning accuracy of the motor; long-term use can lead to positioning deviations and unstable locking. Third, most electronic locks can only achieve locking in one direction, making it difficult to meet the multi-directional locking needs of complex scenarios. Fourth, the internal structure of the lock is often poorly designed, with batteries mixed with control components and transmission mechanisms, making installation, maintenance, and battery replacement difficult.

[0003] A prior art example, referring to patent document CN223089102U, discloses an electronic door lock device and cabinet door. The electronic door lock device includes a lock body and a latch. The lock body contains a drive component, a reduction component, and a locking rod component. The side wall of the lock body has a lock hole communicating with the inner cavity of the lock body. The output end of the drive component is connected to the input end of the reduction component, and the output end of the reduction component is connected to the locking rod component. The drive component can drive the locking rod component to move to a first position or a second position. The latch is connected to a bolt with a lock groove. The latch can move vertically relative to the lock body, allowing the bolt to insert into the lock body through the lock hole. The reduction component converts the high speed and low torque of the drive component into low speed and high torque before outputting it to the locking rod component, thereby driving the locking rod component to move. The locking rod component includes a locking rod assembly and a swing rod. The locking rod assembly (320) is slidably connected to the lock body, and the swing rod is rotatably connected to the lock body. One end of the swing rod is meshed with the gear set, and the other end of the swing rod is connected to the locking rod assembly. The rotation of the swing rod can drive the locking rod assembly to reciprocate between a first position and a second position. The solution shown in the technical example has certain defects. For example, the swing rod and the locking rod assembly adopt a non-linear transmission method. The swing of the swing rod is converted into the linear motion of the locking rod assembly. Therefore, some of the swing force is dispersed (wasted), the force transmission efficiency is reduced, which will lead to the need for greater driving force and is more prone to jamming. The force on the parts is also uneven, making them more susceptible to damage. 2. Its transmission sequence is: driving component - deceleration component - swing rod - second slider - first spring - push rod - first slider. The transmission structure is complex, prone to local failure, and has a low fault tolerance rate, which makes it impossible to achieve normal lock function.

[0004] To solve the above problems, there is an urgent need for an electronic lock that has a buffer transmission function, stable locking, adaptability to multi-directional locking, and a reasonable structural layout. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides an electronic lock, which aims to solve the technical problems of complex transmission structure, poor locking stability, insufficient multi-directional locking ability and unreasonable structural layout of existing electronic locks.

[0006] The technical solution of this utility model to solve its technical problem is: an electronic lock, comprising:

[0007] A lock box, which provides installation space, has a locking opening on the lock;

[0008] A locking block, which is disposed at the locking opening;

[0009] The lock mechanism includes a drive component, a reduction assembly, and a locking rod assembly. The output end of the drive component is in transmission engagement with the input end of the reduction assembly, and the output end of the reduction assembly is in transmission engagement with the locking rod assembly.

[0010] The locking rod assembly includes a translation slider, a locking rod body, a first spring, and a second spring;

[0011] The locking rod body has a locked position and an unlocked position; when the locking rod body is in the locked position, the locking rod body extends at least partially into the locking block; when the locking rod body is in the unlocked position, the locking rod body retracts outside the locking block.

[0012] The translation slider and the output end of the deceleration component form a transmission engagement. The translation slider is provided with a through groove, and the front end of the locking rod body passes through the through groove and extends to the front end of the translation slider.

[0013] The first spring abuts between the front end of the locking rod body and the translation slider, and the second spring abuts between the rear end of the locking rod body and the translation slider. The translation slider forms a transmission engagement with the locking rod body through the first spring and the second spring.

[0014] The driving component drives the translation slider to move forward via a deceleration assembly, and the translation slider drives the locking rod body to switch from the unlocked position to the locked position via a first spring; or, the driving component drives the translation slider to move backward via a deceleration assembly, and the translation slider drives the locking rod body to switch from the locked position to the unlocked position via a second spring.

[0015] Preferably, a slide rail is provided on the inner wall of the lock box, and a guide groove is provided on the translation slider. The slide rail extends into the guide groove so that the translation slider and the slide rail form a sliding engagement.

[0016] Optionally, the front end of the locking rod body is provided with an annular section, the first spring abuts between the annular section and the front end face of the translation slider, and the annular section can abut against the outer wall of the locking block and form a limiting fit.

[0017] Furthermore, the rear end of the translation slider has a receiving cavity, the rear end of the locking rod body has a slot, a limiting spring is provided in the slot, and the second spring abuts between the limiting spring and the inner wall of the receiving cavity.

[0018] In some preferred embodiments of this utility model, the deceleration assembly includes a worm gear, an input gear, a plurality of reduction gears, and an output gear;

[0019] The worm is sleeved on the output shaft of the drive component, and the input gear has a worm wheel section, which meshes with the worm.

[0020] The reduction gear transmission is connected between the input gear and the output gear;

[0021] The translation slider has a rack, which meshes with an output gear so that the output gear and the translation slider form a transmission engagement.

[0022] Preferably, the input gear, reduction gear, and output gear are all double gears.

[0023] In some preferred embodiments of this utility model, the lock block has one or more lock slots for external latches to engage.

[0024] Specifically, when there are two or more locking slots, each locking slot has a different opening direction.

[0025] In some preferred embodiments of this utility model, the lock box has a battery cavity and a control cavity, the lock body mechanism is disposed in the control cavity, and a battery is disposed in the battery cavity;

[0026] The control cavity is equipped with a control circuit board, which is electrically connected to the battery and the drive component.

[0027] The working process of this utility model is as follows:

[0028] Locking process: The user sends a locking command to the control circuit board, which controls the drive component (preferably a motor) to rotate forward. The output shaft of the drive component drives the worm gear to rotate, and the worm gear drives the input gear to rotate. After transmission through the reduction gear, the output gear drives the translation slider to move forward along the slide rail. The translation slider pushes the locking rod body forward through the first spring until the front end of the locking rod body extends into the locking groove of the locking block. The annular section abuts against the outer wall of the locking block, and the locking rod cooperates with the external latch inserted into the locking block to achieve locking.

[0029] Unlocking process: After the user sends the unlock command, the control circuit board controls the drive component to reverse, and through the deceleration component, the translation slider moves backward. The translation slider pushes the locking rod body backward through the second spring until the locking rod body exits the locking block groove. The locking rod separates from the external latch inserted into the locking block, and the unlocking is completed.

[0030] The beneficial effects of this utility model are as follows:

[0031] 1. Buffer transmission protection: The first and second springs realize the flexible transmission between the sliding slider and the locking bar body, effectively buffering the impact load during locking or unlocking, avoiding damage to components caused by door deformation or external impact, and extending the service life of the lock.

[0032] II. Stable Guide Transmission: The cooperation between the slide rail and the guide groove ensures the smooth movement of the translation slider. Combined with the double gear transmission of the deceleration component, it improves the movement accuracy and locking stability of the locking rod body.

[0033] 3. Multi-directional locking adaptation: The multi-directional opening lock slots of the lock block can meet the locking needs in different scenarios, improving the versatility and security of the lock.

[0034] IV. Reasonable layout and maintenance: The battery compartment and control compartment of the lock box are designed separately, which facilitates battery replacement and maintenance of control components, and improves ease of use. Attached Figure Description

[0050] Example 1

[0051] Reference Figures 1 to 11 An electronic lock includes: a lock box 1 for providing installation space, wherein a locking opening 11 is provided on the lock; a lock block 2 disposed at the locking opening 11; and a lock body mechanism 3 including a drive component 31, a reduction gear assembly 32, and a lock rod assembly 33, wherein the output end of the drive component 31 is in transmission engagement with the input end of the reduction gear assembly 32, and the output end of the reduction gear assembly 32 is in transmission engagement with the lock rod assembly 33; the lock rod assembly 33 includes a translation slider 331, a lock rod body 332, a first spring 333, and a second spring 334; wherein the lock rod body 332 has a locked position 3a and an unlocked position 3b; when the lock rod body 332 is in the locked position 3a... The locking rod body 332 extends at least partially into the locking block 2; when the locking rod body 332 is in the unlocked position 3b, the locking rod body 332 retracts out of the locking block 2; the translation slider 331 forms a transmission engagement with the output end of the deceleration component 32, and the translation slider 331 has a through groove, through which the front end of the locking rod body 332 extends to the front end of the translation slider 331; the first spring 333 abuts between the front end of the locking rod body 332 and the translation slider 331, and the second spring 334 abuts between the rear end of the locking rod body 332 and the translation slider 331, and the translation slider 331 forms a transmission engagement with the locking rod body 332 through the first spring 333 and the second spring 334.

[0052] Upon startup, the drive component 31 drives the translation slider 331 to move forward via the deceleration assembly 32, and the translation slider 331 drives the locking rod body 332 to switch from the unlocked position 3b to the locked position 3a via the first spring 333; or, the drive component 31 drives the translation slider 331 to move backward via the deceleration assembly 32, and the translation slider 331 drives the locking rod body 332 to switch from the locked position 3a to the unlocked position 3b via the second spring 334.

[0053] The above describes the basic structural design of this utility model. The lock box 1 provides overall installation space, and the locking block 2 at the locking opening 11 serves as a mechanical stop for the locking rod body 332. The drive component 31 is generally a motor, outputting power outward in the form of rotation. The slot design allows the locking rod to maintain axial freedom when the translation slider 331 moves, preventing direct contact between the translation slider 331 and the locking rod. Therefore, the driving force needs to be indirectly transmitted through the first spring 333 / second spring 334.

[0054] Specifically, the working principle of the first spring 333 / second spring 334 is as follows: Under the action of the driving component 31, the translation slider 331 first changes its position, causing a change in the relative positional relationship between the translation slider 331 and the locking rod body 332, thereby reducing or increasing the size of the space occupied by the first spring 333 / second spring 334. According to the change in the size of the space, the first spring 333 / second spring 334 adaptively contracts or extends (deforms), thereby applying a certain force to the locking rod body 332 to drive the locking rod body 332 forward or backward.

[0055] This disclosure effectively solves the problems of complex transmission mechanisms and weak anti-interference capabilities in traditional electronic locks by using a dual-spring driven locking rod assembly 33. Its advantages lie in directly converting the rotational motion of the motor into the elastic potential energy of the springs, achieving bidirectional transmission through the synergistic action of the two springs. It features a simple structure and controllable cost. Furthermore, the elastic connection of the two springs can compensate for assembly errors and absorb the instantaneous impact force during motor start-up and shutdown, providing a protective function.

[0056] Preferably, refer to Figure 11 The inner wall of the lock box 1 is provided with a slide rail 12, and the translation slider 331 is provided with a guide groove 3311. The slide rail 12 extends into the guide groove 3311, so that the translation slider 331 and the slide rail 12 form a sliding engagement. The engagement of the slide rail 12 and the guide groove 3311 provides precise guidance and constraint for the reciprocating motion of the translation slider 331, effectively solving the problems of possible offset and jamming of the slider during movement, forcing the slider to move along a preset straight line, and ensuring that the locking rod body 332 is always aligned with the locking block 2. On the other hand, in traditional designs, the translation slider 331 may directly contact and slide with the inner wall surface of the lock box 1, resulting in a large friction area and high resistance. Long-term use can easily lead to jamming due to wear. In this solution, the surface contact is transformed into line contact, which greatly reduces the friction area, makes the slider move more smoothly, and reduces the load on the drive component 31 (such as the motor). Furthermore, when the lock is subjected to external impact (such as the door lock being hit or the cabinet lock being shaken), the sliding slider 331 is easily affected by external force and will deviate. The rigid cooperation between the slide rail 12 and the slide groove can effectively resist the lateral impact force and prevent the slider from leaving the preset track due to impact, thereby indirectly protecting the cooperation relationship between the lock rod body 332 and the lock block 2.

[0057] It is worth mentioning that the guide rail 12 ensures the linear motion of the translation slider 331, so that the rack 3314 and the output gear 324 always mesh well, avoiding uneven wear on the tooth surface.

[0058] In this embodiment, refer to Figure 1 The lock block 2 has one or more lock slots 21 for external latches 6 to access. Specifically, when there are two or more lock slots 21, each lock slot 21 has a different opening direction. Lock slots 21 with different opening directions need to be matched with external latches 6 of corresponding shapes to meet the locking requirements of external latches 6 in different directions, making the application scenarios more diversified.

[0059] Preferably, refer to Figures 9-11 The lock box 1 has a battery compartment 13 and a control compartment 14. The lock body mechanism 3 is disposed in the control compartment 14, and a battery 5 is disposed in the battery compartment 13. A control circuit board 4 is disposed in the control compartment 14, and the control circuit board 4 is electrically connected to the battery 5 and the drive component 31 respectively. The partitioned design of the battery compartment 13 and the control compartment 14 avoids damage to the circuit board from battery leakage, dust, and mechanical impact.

[0060] Example 2

[0061] Reference Figures 7-10 The preferred configuration for the first spring 333 and the second spring 334 is as follows:

[0062] 1. Without the annular section 3321, the first spring 333 is directly fitted onto the lock rod, which may cause the following problems: the spring is prone to skew along the lock rod axis when compressed / extended, resulting in uneven force transmission; the lack of a clear support reference at both ends of the spring may lead to inconsistent preload due to assembly errors, affecting the stability of locking / unlocking force. To solve the aforementioned defects, improve the assembly processability of the lock, and enhance its reliability, the following solution is adopted: the front end of the lock rod body 332 is provided with an annular section 3321, and the first spring 333 abuts against the annular section 3321 and the front end face of the translation slider 331. The annular section 3321 serves as the front positioning surface of the first spring 333. The flatness of the annular section 3321 ensures that the spring is subjected to uniform force (avoiding unilateral force). The spring is constrained between the annular section 3321 and the front surface of the translation slider 331, forming an axial constraint to ensure that the spring always extends and retracts along the locking rod axis, resulting in higher force transmission efficiency. On the other hand, the annular section 3321 can abut against the outer wall of the locking block 2 and form a limiting fit, which can prevent the locking rod from excessively extending into the locking block 2 due to loss of control of the drive component 31 (such as a motor) or transmission error of the reduction component 32, causing mechanical damage such as bending of the locking rod and breakage of the locking block 2. Furthermore, the abutment position of the annular section 3321 and the locking block 2 is fixed each time locking, ensuring that the depth of the locking rod extending into the locking block 2 is completely consistent, avoiding problems such as insecure locking or jamming due to different extension amounts.

[0063] II. Without the constraint of the limiting spring 3323 and the receiving cavity 3313, the second spring 334 may experience the following problems: it may skew radially along the locking rod during compression / extension, causing the spring force direction to deviate from the axial direction and increasing the resistance to the locking rod movement; it may also detach from the rear end of the locking rod due to vibration or impact, resulting in failure of the unlocking power transmission. To solve the problem of stable assembly of the second spring 334 and achieve the rear end limiting constraint of the locking rod body 332 and the translation slider 331, the following solution is adopted: the rear end of the translation slider 331 has a receiving cavity 3313, the rear end of the locking rod body 332 has a groove 3322, the groove 3322 is provided with a limiting spring 3323, and the second spring 334 abuts against the inner wall of the receiving cavity 3313.

[0064] Specifically, the limiting snap ring 3323 provides a clear rear reference surface for the second spring 334, and the inner wall of the receiving cavity 3313 provides a front reference surface, so that the second spring 334 is strictly limited between two parallel planes, ensuring that the elastic force is always transmitted along the axial direction of the locking rod. This achieves double-line limiting of the second spring 334: ensuring that the locking rod body 332 and the translation slider 331 always remain in a "transmissible" state, and that they will not separate even when the spring is under extreme compression / extension; and preventing the locking rod from disengaging from the slider due to malfunction of the drive component 31 (such as excessive rotation of the motor), which would cause the lock to fail.

[0065] Example 3

[0066] In this preferred embodiment, refer to Figures 3-4 The reduction assembly 32 includes a worm gear 321, an input gear 322, several reduction gears 323, and an output gear 324. The worm gear 321 is sleeved on the output shaft of the drive component 31. The input gear 322 has a worm wheel section 3221, which meshes with the worm gear 321. The reduction gears 323 are connected between the input gear 322 and the output gear 324. The translation slider 331 has a rack 3314, which meshes with the output gear 324, so that the output gear 324 and the translation slider 331 form a transmission engagement.

[0067] The reduction assembly 32 described above has the following characteristics: 1. The superposition of the large transmission ratio of the worm gear 321 and the multi-stage reduction gear 323 can amplify the torque of the drive component 31 by hundreds of times, ensuring that the locking rod can reliably extend into / out of the locking block 2, and can still work normally even under harsh conditions such as low temperature and slight corrosion. 2. The self-locking property of the worm gear 321 improves the safety of the anti-locking mechanism. 3. The low-speed, high-torque output of the reduction assembly 32 provides a stable power foundation for the elastic transmission of the double springs (first spring 333 and second spring 334). Even if the springs generate additional resistance due to buffering (such as slight jamming of the locking rod body 332), sufficient torque can still push the slider to continue moving, compressing the springs to absorb errors and avoid jamming caused by insufficient power. 4. The gear and rack transmission will generate a certain lateral force (radial component of the gear on the rack), and the rigid constraint of the slide rail 12 and the guide groove 3311 can offset this force, preventing the translation slider 331 from shifting due to lateral force, and ensuring that the rack and output gear 324 are always precisely meshed.

[0068] Preferably, the input gear 322, reduction gear 323, and output gear 324 are all double gears. The "coaxial double gear ring" characteristic of the double gears perfectly adapts to the needs of multi-stage reduction, achieving efficient and stable power transmission within the limited space of the lock box 1. Preferably, the double-gear structure design is as follows: 1. Input gear 322: coaxially integrates the worm gear section 3221 and the small gear ring; 2. Reduction gear 323: typically a combination of a small gear ring and a large gear ring, with the small gear ring acting as the driven gear of the previous stage and the large gear ring acting as the driving gear of the next stage; 3. Output gear 324: coaxially integrates a large gear ring and a small gear ring.

[0069] The assembly process of this utility model is as follows:

[0070] The worm gear 321 of the reduction assembly 32 is sleeved and fixed on the output shaft of the drive component 31. The input gear 322, the reduction gear 323, and the output gear 324 are sequentially installed in the control cavity 14 through the rotating shaft to ensure smooth gear meshing.

[0071] The rear end of the locking rod body 332 passes through the through groove of the second spring 334 and the translation slider 331. A limiting spring 3323 is installed in the locking groove 3322 at the rear end of the locking rod body 332, so that the second spring 334 abuts against the limiting spring 3323 and the inner wall of the cavity 3313 of the translation slider 331. A first spring 333 is sleeved on the front end of the locking rod body 332, so that the first spring 333 abuts against the annular section 3321 and the front end face of the translation slider 331.

[0072] The assembled locking rod assembly 33 is installed in the control cavity 14, so that the straight rack 3314 of the translation slider 331 meshes with the output gear 324, and the guide groove 3311 of the translation slider 331 cooperates with the slide rail 12 on the inner wall of the lock box 1.

[0073] Fix the lock block 2 at the locking opening 11 of the lock box 1, so that the front end of the lock rod body 332 corresponds to the lock groove 21 of the lock block 2; fix the control circuit board 4 in the control cavity 14, and connect the wires of the battery 5 to the control circuit board 4 and the control circuit board 4 to the drive component 31.

[0074] It is worth noting that the other technical solutions of this utility model are all existing technologies, and therefore will not be described in detail.

[0075] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
