Description

Technical Field

[0001] This utility model relates to the field of locks, and more specifically, to a cabinet door lock. Background Technology

[0002] Currently, most common cabinet door locks use a simple bolt-type structure. The locking process requires the user to manually align the cabinet door with the cabinet body and then push the bolt into the latch. This structure is not only cumbersome, but also often results in the bolt failing to properly insert due to misalignment, causing inconvenience in daily use. Existing cabinet door locks cannot automatically lock when the cabinet door is closed, lacking the intelligent and user-friendly experience sought after in modern home furnishing products, resulting in a subpar user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a cabinet door lock that has a compact structure, can automatically lock when the door is closed, and operates stably and reliably.

[0004] A cabinet door lock includes a housing with a slot, and the housing contains a spacer component, a locking component, and a drive component; The occupant assembly includes an occupant block and a first spring. The occupant block is configured to extend into the slot under the action of the first spring. The locking assembly includes a sliding seat, a rotating rod, and a second spring. The upper end of the sliding seat is provided with a pin. The second spring is sleeved on the rotating rod. The driving assembly is used to drive the rotating rod to rotate, so as to drive the sliding seat to rise and fall through the second spring. When the occupant block is located in the slot, it blocks the pin; when the occupant block exits the slot, the pin extends into the slot under the action of the second spring.

[0005] In the above technical solution, by setting a sizing block that can horizontally extend and retract under the action of a spring, and a sliding seat and pin linked to a rotating rod via the spring, the sizing block can effectively block the pin when it extends into the slot, providing mechanical positioning for the unlocked state. When the sizing block is pushed away by the latch, the pin can quickly rise under the drive of the second spring to complete the locking, realizing automatic locking when the wardrobe door is closed. The drive component indirectly drives the sliding seat to descend through the rotating rod and the second spring, making the unlocking action smooth and minimizing the impact on the drive component. The overall structure is reasonably laid out and operates reliably.

[0006] Furthermore, the outer circumferential surface of the rotating rod is provided with a pin, the sliding seat includes an upper baffle, a lower baffle and a side plate, the rotating rod passes through the upper baffle and the lower baffle, and the second spring is located between the upper baffle and the lower baffle.

[0007] In the above technical solution, when the pin rotates, it extends into the spiral of the second spring, thereby pushing the second spring to move upward or downward as a whole. When the second spring moves between the pin and the lower baffle, its elastic force drives the sliding seat to move downward, causing the pin to exit the slot. When the second spring moves between the pin and the upper baffle, its elastic force drives the sliding seat to move upward, giving the pin a tendency to pop out upward, so that when the occupant block exits the slot, the pin can pop out quickly.

[0008] Furthermore, the side plate is provided with an anti-rotation groove, and one end of the second spring extends into the anti-rotation groove.

[0009] In the above technical solution, an anti-rotation groove is opened on the side plate of the sliding seat and one end of the second spring is inserted into it, thereby restricting the rotation of the second spring itself, so that the pin can drive the second spring to move up and down by rotating.

[0010] Furthermore, the drive assembly includes a drive component and a gear set, one end of the rotating rod is provided with a transmission gear, and the drive component is connected to the transmission gear through the gear set.

[0011] In the above technical solution, the structure of driving the transmission gear through the gear set by the driving component can achieve effective power transmission.

[0012] Furthermore, a sensing component is provided inside the housing near the occupant assembly. The sensing component includes a sensing switch, a sensing rod, and a third spring. The axial direction of the sensing rod is parallel to the moving direction of the occupant block. The occupant block has a pushing part opposite to the sensing rod. The sensing switch is located at one end of the moving path of the sensing rod, and the third spring is sleeved on the sensing rod.

[0013] In the above technical solution, by setting a sensing component linked to the occupant block, the sensing rod is directly driven by the push part on the occupant block. This converts the displacement of the occupant block when the cabinet door is locked into an electrical signal, so that the door lock status can be detected in real time and accurately. The moving direction of the sensing rod is consistent with that of the occupant block. The structure is compact and the response is direct and rapid, providing a foundation for the status monitoring and intelligent control of the system.

[0014] Furthermore, a circuit board is provided inside the housing, and the circuit board is electrically connected to the inductive switch and the drive assembly.

[0015] In the above technical solution, by connecting the inductive switch and the drive component together to the circuit board inside the housing, the signal transmission between the components is stable and reliable, while facilitating production assembly and subsequent maintenance.

[0016] Furthermore, it also includes a locking assembly, which includes a locking part that can rotatably extend into the slot and push against the occupant block, and the pin is configured to extend into the locking part.

[0017] In the above technical solution, a latch assembly with a latching part is provided, so that the latch can push the occupant block and be locked by the pin when the door is closed, thus realizing the continuity of the closing and locking actions.

[0018] Furthermore, the end of the occupant block is provided with an arc-shaped groove to facilitate the sliding of the locking part.

[0019] In the above technical solution, an arc-shaped groove is provided at the end of the occupant block to provide a smooth guide slope for the latching part of the lock, so that the latching part can slide in smoothly when pushing the occupant block, effectively reducing noise, impact and wear of parts during contact, improving the user's feel when closing the door, and extending the service life of the occupant block and the latching part.

[0020] Compared with existing technologies, the advantages of this invention are as follows: By setting a horizontally retractable occupant block under the action of a spring, and a sliding seat and pin linked to a rotating rod via the spring, the occupant block effectively blocks the pin when it extends into the slot, providing mechanical positioning for the unlocked state. When the occupant block is pushed away by the latch, the pin can quickly rise under the drive of the second spring to complete the locking, thus achieving automatic locking when the wardrobe door is closed. The drive assembly indirectly drives the sliding seat to descend via the rotating rod and the second spring, making the unlocking action smooth and minimizing the impact on the drive assembly. The overall structure is reasonably laid out and operates reliably. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] Please refer to Figures 1 to 5 In a preferred embodiment, the cabinet door lock of this utility model includes a housing 1 with a slot 11. The housing 1 contains a spacer component 2, a locking component 3, and a driving component 4. The spacer component 2 includes a spacer block 21 and a first spring 22. The spacer block 21 is configured to extend into the slot 11 under the action of the first spring 22. The locking component 3 includes a sliding seat 31, a rotating rod 32, and a second spring 33. A pin 315 is provided at the upper end of the sliding seat 31. The second spring 33 is sleeved on the rotating rod 32. The driving component 4 drives the rotating rod 32 to rotate, thereby causing the sliding seat 31 to rise and fall via the second spring 33. When the spacer block 21 is located in the slot 11, it blocks the pin 315. When the spacer block 21 exits the slot 11, the pin 315 extends into the slot 11 under the action of the second spring 33.

[0030] For example, the slot 11 is formed on one side of the housing 1, the occupant component 2 is located at one end of the slot 11 in the horizontal direction, and the first spring 22 is located between the occupant block 21 and the housing 1, and is axially horizontal. The occupant block 21 can slide in the horizontal direction, thereby extending into or out of the slot 11. The locking component 3 is located below the slot 11, and the slot wall on the lower side of the slot 11 has a through hole for the pin 315 to pass through. The pin 315 can extend into the slot 11 from bottom to top under the elastic force of the second spring 33.

[0031] By incorporating a horizontally extendable occupant block 21 under spring action, and a sliding seat 31 and pin 315 linked to the rotating rod 32 via the spring, the occupant block 21 effectively blocks the pin 315 when it extends into the slot 11, providing mechanical positioning for the unlocked state. When the occupant block 21 is pushed away by the latch, the pin 315 can quickly rise under the drive of the second spring 33 to complete the locking, thus achieving automatic locking when the wardrobe door is closed. The drive assembly 4 indirectly drives the sliding seat 31 to descend via the rotating rod 32 and the second spring 33, making the unlocking action smooth and minimizing the impact on the drive assembly 4. The overall structure is reasonably laid out and operates reliably.

[0032] A pin 321 is provided on the outer circumference of the rotating rod 32. The sliding seat 31 includes an upper baffle 311, a lower baffle 312, and a side plate 313. The rotating rod 32 passes through the upper baffle 311 and the lower baffle 312. The second spring 33 is located between the upper baffle 311 and the lower baffle 312. When the pin 321 rotates, it extends into the spiral of the second spring 33, thereby pushing the second spring 33 to move up or down as a whole. When the second spring 33 moves between the pin 321 and the lower baffle 312, its elastic force drives the sliding seat 31 to move downward, causing the pin 315 to exit the slot 11. When the second spring 33 moves between the pin 321 and the upper baffle 311, its elastic force drives the sliding seat 31 to move upward, giving the pin 315 an upward pop-out tendency, so that when the occupant block 21 exits the slot 11, the pin 315 can quickly pop out.

[0033] The side plate 313 has an anti-rotation groove 314, and one end of the second spring 33 extends into the anti-rotation groove 314. For example, the anti-rotation groove 314 extends along the height direction of the side plate 313, and one end of the second spring 33 passes through the anti-rotation groove 314. When the second spring 33 moves vertically, its end moves along the extending direction of the anti-rotation groove 314. By providing an anti-rotation groove 314 on the side plate 313 of the sliding seat 31 and allowing one end of the second spring 33 to extend into it, the rotation of the second spring 33 itself is restricted, allowing the pin 321 to rotate to drive the second spring 33 to move up and down.

[0034] The drive assembly 4 includes a drive component 41 and a gear set 42. One end of the rotating rod 32 is provided with a transmission gear 322, and the drive component 41 is connected to the transmission gear 322 through the gear set 42. The drive component 41 is fixedly installed inside the housing 1. In this embodiment, the drive component 41 can be a motor, and its output end is connected to the transmission gear 322 through the gear set 42, thereby realizing the effective transmission of power.

[0035] A sensing component 5 is provided inside the housing 1 near the occupant component 2. The sensing component 5 includes a sensing switch 51, a sensing rod 52, and a third spring 53. The axial direction of the sensing rod 52 is parallel to the moving direction of the occupant block 21. The occupant block 21 is provided with a pushing part 212 opposite to the sensing rod 52. The sensing switch 51 is located at one end of the moving path of the sensing rod 52, and the third spring 53 is sleeved on the sensing rod 52.

[0036] By setting up a sensing component 5 that is linked to the occupant block 21, the sensing rod 52 can be directly driven by the push part 212 on the occupant block 21. This allows the displacement of the occupant block 21 when the cabinet door is locked to be converted into an electrical signal, so that the door lock status can be detected in real time and accurately. The moving direction of the sensing rod 52 is consistent with that of the occupant block 21. The structure is compact and the response is direct and rapid, providing a foundation for the system's status monitoring and intelligent control.

[0037] In this embodiment, a circuit board 6 is provided inside the housing 1, and the circuit board 6 is electrically connected to the inductive switch 51 and the drive assembly 4. By connecting the inductive switch 51 and the drive assembly 4 together to the circuit board 6 inside the housing 1, the signal transmission between the components is stable and reliable, and it also facilitates production assembly and subsequent maintenance.

[0038] The cabinet door lock in this embodiment also includes a latch assembly 7, which includes a latch part 71. The latch part 71 can rotatably extend into the slot 11 and push the occupant block 21. The pin 315 is configured to extend into the latch part 71. In a specific implementation, the housing 1 can be installed on the door frame of the cabinet door, with its slot 11 facing the hinge side of the cabinet door. The latch assembly 7 is installed on the hinge at a position corresponding to the housing 1. When the hinge is closed, the latch part 71 slides across the slot 11 and pushes the occupant block 21, while the pin 315 extends into the lock hole 72 of the latch part 71, thereby realizing the continuity of the closing and locking actions.

[0039] The end of the placeholder block 21 is provided with an arc-shaped groove 211 to facilitate the sliding of the latching part 71. The arc-shaped groove 211 at the end of the placeholder block 21 provides a smooth guide slope for the latching part 71 of the latch, so that the latching part 71 can slide in smoothly when pushing the placeholder block 21, effectively reducing noise, impact and wear of parts during contact, improving the user's feel when closing the door, and extending the service life of the placeholder block 21 and the latching part 71.

[0040] To facilitate understanding of the cabinet door lock, its working principle is described below: In the unlocked state, the placeholder block 21 extends into the slot 11 and blocks the pin 315 on the lower side of the slot 11. At this time, the second spring 33 is in a compressed state, and the pin 315 tends to rise. When the cabinet door is closed, the latch part 71 of the latch slides across the slot 11 and pushes the placeholder block 21, causing the placeholder block 21 to exit the slot 11. At this time, the pin 315 is no longer blocked, and the elastic force of the second spring 33 is released, causing the pin 315 to rise and extend into the latch part 71, completing the locking. At this time, the placeholder block 21 triggers the sensor switch 51 through the sensor rod 52, and the circuit board 6 determines that the cabinet door lock is in the locked state. When the user performs an unlocking action using existing methods such as key, password, card swipe, or facial recognition, the drive component 41 drives the pin 315 to descend, thereby unlocking the door. When the latch 71 leaves the slot 11, the occupant block 21 extends into the slot 11 under the elastic force of the first spring 22. At this time, the sensing rod 52 moves with the occupant block 21 and separates from the sensing switch 51. The circuit board 6 determines that the cabinet door lock is in the unlocked state. The driving component 41 drives the pin 315 to rise, while compressing the second spring 33 between the pin 321 and the upper baffle 311, so that the pin 315 has an upward trend, ensuring that the pin 315 can automatically pop out when locking next time.
