Detailed Implementation
[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0036] like Figure 1-11As shown, an embodiment of this utility model provides an automatic door lock, comprising: a bolt 1, a lock housing 2, a telescopic assembly 3, a locking assembly 4, and a processing unit. The bolt 1 contains a reed switch 14. The lock housing 2 has a notch 21. The telescopic assembly 3 is disposed within the lock housing 2 and has a telescopic end that can actively extend or retract relative to the notch. The locking assembly 4 includes a locking housing 41, a limiting member 42, and two latch arms 43 that can move relative to each other and encircle the bolt 1. The locking housing 41 is connected to the telescopic end and contains a trigger magnet 44. One end of each latch arm 43 is hinged to the locking housing 41. Both ends of the limiting member 42 are connected to the other ends of the latch arms 43 to apply a force to the latch arms 43 to restrict their opposite movement. The processing unit is electrically connected to the reed switch 14 and the telescopic assembly 3 and confirms the engagement state of the latch arms 43 and the locking assembly 4 based on the signal from the reed switch 14.
[0037] In this utility model, a bolt 1, a lock housing 2, a telescopic assembly 3, a locking assembly 4, and a processing unit are provided. The bolt 1 contains a reed switch 14. The lock housing 2 has a notch 21. The telescopic assembly 3 is disposed in the lock housing 2 and has a telescopic end that can actively extend or retract relative to the notch. The locking assembly 4 includes a locking housing 41, a limiting member 42, and two latch arms 43 that can move relative to each other and encircle the bolt 1. The locking housing 41 is connected to the telescopic end and contains a trigger magnet 44. One end of each latch arm 43 is hinged to the locking housing 41. Both ends of the limiting member 42 are respectively connected to the other ends of the latch arms 43 to apply a force to the latch arms 43 to restrict their opposite movement. The processing unit is electrically connected to the reed switch 14 and the telescopic assembly 3 and confirms the engagement state of the latch arms 43 and the locking assembly 4 based on the signal from the reed switch 14. In use, when the locking component 4 is locked to the bolt 1, the reed switch 14 generates a signal under the triggering of the trigger magnet 44, and the processing unit confirms that the locking component 4 and the bolt 1 are engaged based on the signal from the reed switch 14.
[0038] The solution of this utility model can automatically complete the unlocking and locking actions to provide a better user experience.
[0039] Specifically, the bolt 1 includes a carrier plate 11 and a bolt body 12. The bolt body 12 is fixed to the carrier plate 11, and the latch arms 43 can encircle the bolt body 12 from both sides to restrict the movement of the bolt body 12 relative to the lock housing 2. In use, the carrier plate 11 is fixed to one component, the lock housing 2 is fixed to another component, and the latch arms 43 encircle the bolt body 12 to lock the two components. When the external tension on the bolt body 12 is greater than the locking tension between the latch arms 43, the two components can be separated relative to each other.
[0040] The plug body 12 can take various shapes. In some feasible embodiments, the plug body 12 is cuboid. In some feasible embodiments, the plug body 12 is triangular prism; while in this embodiment, the plug body 12 is spindle-shaped.
[0041] Furthermore, the bolt 1 also includes an upper cover 13, which is disposed on top of the bolt body 12, with the edge of the upper cover 13 protruding relative to the edge of the bolt body 12. This arrangement is intended to ensure that the protruding portion of the upper cover 13 relative to the bolt body 12 can press down on the latch arm 43 when the latch arm 43 encircles the bolt body 12, preventing the latch arm 43 from detaching from the bolt body 12.
[0042] In this embodiment, the bolt body 12 has a groove 121, the reed switch 14 is embedded in the groove 121, and the bolt body 12 also includes a locking member 122, which engages in the groove 121 to enclose the reed switch 14 in the groove 121.
[0043] Furthermore, the engaging component 122 includes a plate 122a, with a supporting protrusion 122b formed in the center of the plate 122a, and engaging grooves for wires formed on both sides of the supporting protrusion 122b. In use, the reed switch 14 is placed on the supporting protrusion 122b, and the lead wire of the reed switch 14 is engaged in the engaging groove and extends to the outside of the plug body 12.
[0044] In this embodiment, such as Figure 2 As shown, the telescopic component 3 includes a motor 31, a push rack 32, and a gear set 33. The motor 31 is fixed inside the door lock housing 2 and meshes with the gear set 33. The push rack 32 is movably disposed inside the door lock housing 2, with one end connected to the locking component 4. The push rack 32 meshes with the gear set 33. The motor 31 drives the gear set 33 to rotate, thereby causing the push rack 32 to move relative to the door lock housing 2, achieving the technical effect of the push rack 32 extending or retracting relative to the notch 21. The motor 31 is electrically connected to the processing unit.
[0045] In some other feasible embodiments, such as Figure 5-6 As shown, the telescopic component 3 includes a reduction motor 31a, a rack 32a, and a gear 33a. The reduction motor 31a is fixed inside the door lock housing 2, and the gear 33a is fixed to the rotating end of the reduction motor 31a. The rack 32a is movably embedded inside the door lock housing 2, with one end connected to the locking housing 41. The rack 32a meshes with the gear 33a. When the reduction motor 31a rotates forward, the gear 33a rotates, pushing the rack 32a to move relative to the door lock housing 2, thus pushing the locking housing 41 out of the notch 21. When the reduction motor 31a rotates in reverse, the gear 33a rotates, pushing the rack 32a to move relative to the door lock housing 2, thus pulling the locking housing 41 into the notch 21.
[0046] Furthermore, one end of the rack 32a is hinged to the locking housing 41, and there is a rotational clearance between the locking housing 41 and the rack 32a, so that the locking housing 41 can rotate to tilt relative to the horizontal plane. The purpose of this design is that the movement trajectory of the bolt 12 is arc-shaped, and the locking housing 41, after extending out of the notch 21, tilts at an angle under the action of gravity, which can match the movement trajectory of the bolt 12, facilitating the engagement of the locking assembly 4 with the bolt 12.
[0047] Furthermore, a hinge end 321 is formed on one end of the rack 32a near the locking housing 41, which is hinged to the locking housing 41. The end of the rack 32a extends to form an abutment end 322 that can abut against the bottom of the locking housing 41. The thickness between the hinge end 321 and the abutment end 322 is greater than the thickness of the locking housing 41. When the locking housing 41 extends out of the notch 21, under the action of gravity, the locking housing 41 rotates relative to the hinge end 321 until it abuts against the abutment end 322. At this time, the locking housing 41 is inclined relative to the horizontal plane, which can match the movement trajectory of the bolt 12, facilitating the engagement of the locking assembly 4 with the bolt 12.
[0048] Furthermore, a cavity is formed inside the locking housing 41, and the limiting member 42 and the latch arm 43 are disposed in the cavity. A locking notch 411 communicating with the cavity is provided at the end of the locking housing 41, and the end of the latch arm 43 is located at the locking notch 411.
[0049] Furthermore, the limiting member 42 is a spring, with its two ends fixed to the latch arm 43 respectively, and the spring provides a force that resists the opposite movement of the latch arm 43.
[0050] Furthermore, one end of the latch arm 43 is hinged to the inside of the locking housing 41, and the other end of the latch arm 43 is a free end, bent into a shape that matches one side of the bolt body 12. The middle part of the latch arm 43 is connected to the limiting member 42.
[0051] Specifically, it also includes a pair of latch arm pressing components 5, which are disposed inside the door lock housing 2. The locking housing 41 has pressing through holes 412 on both sides. When the locking housing 41 is located inside the door lock housing 2, the latch arm pressing components 5 partially extend into the pressing through holes 412 and press against the latch arm 43.
[0052] Furthermore, the latch arm pressing assembly 5 includes a pressing rod 51, a pressing roller 52, and a pressing spring 53. One end of the pressing rod 51 is hinged to the inner wall of the door lock housing 2, and the other end of the pressing rod 51 corresponds to the pressing through hole 412. The pressing roller 52 is fixed on the free end of the pressing rod 51. One end of the pressing spring 53 is fixed to the inner wall of the door lock housing 2, and the other end is fixed to the pressing rod 51. When the locking housing 41 is located inside the door lock housing 2, the pressing spring 53 applies a force to the pressing rod 51 to compress the latch arm 43, so that the latch arm 43 moves relative to the bolt body 12.
[0053] The advantage of the latch arm pressing assembly 5 is that, in the prior art, a relatively thick spring is often used to connect the latch arm, and the tension on the latch arm is single and linear. However, in this application, three springs are used (one limiting member 42 and two pressing springs 53). When the locking housing 41 is located outside the door lock housing 2, only the limiting member 42 acts on the latch arm 43, and the force is small, which makes it easy for the user to apply force to pull the bolt 12 out of the latch arm 43 (unlocking action) or push the bolt 12 between the latch arms 43 (locking action). When the locking housing 41 retracts into the door lock housing 2, the pressing springs 53 apply force to the latch arm 43 through the pressing rod 51, and the latch arm 43 holds the bolt 12 tightly so that it does not come out.
[0054] Specifically, it also includes a triggering component 6 and an electric switch 7. The electric switch 7 is used to detect the state of the bolt 1 and the latch arm 43. The triggering component 6 is movably disposed within the door lock housing 2. The triggering component 6 can actuate the electric switch 7 when the bolt 12 is inside the door lock housing 2.
[0055] Furthermore, a button is provided on the surface of the electric switch 7, the bolt body 12 is located inside the door lock housing 2, and the triggering component 6 can press the button to trigger the electric switch 7.
[0056] Furthermore, the triggering component 6 includes a trigger rod 61, a trigger spring, and a trigger element 62. The trigger rod 61 is movably disposed within the door lock housing 2. One end of the trigger spring is fixed to the inner wall of the housing 24, and the other end is fixed to the trigger rod 61. The trigger spring allows the trigger rod 61 to be elastically connected to the door lock housing 2. One end of the trigger rod 61 has an abutting end that abuts against the bolt 12. The trigger element 62 is pivotally connected to the door lock housing 2. One end of the trigger element 62 is hinged to the trigger rod 61, and the other end is a free end. When the bolt 11 abuts against the trigger rod 61, it pushes the trigger rod 61 to move, thereby causing the trigger element 62 to rotate relative to the door lock housing 2, causing the trigger element 62 to disengage from the button on the surface of the electric switch 7, thus triggering the electric switch 7.
[0057] In use, when unlocking is required, when the motor 31 rotates forward, the gear set 33 rotates, pushing the push rack 32 to move relative to the door lock housing 2 to the front stop point, pushing the locking housing 41 out of the notch 21 (a distance of 9 cm). The latch arm pressing component 5 gradually disengages from the latch arm 43, and the force of the latch arm 43 encircling the bolt body 12 gradually decreases. The bolt body 12 also moves relative to the door lock housing 2 under the action of the locking housing 41. When the locking housing 41 reaches its maximum extension distance, the latch arm pressing component 5 completely disengages from the latch arm 43. The latch arm 43 only encircles the bolt body 12 under the action of the limiting member 42. At this time, a gap is formed between the bolt body 12 and the door lock housing 2, completing the unlocking action. After the reed switch 14 separates from the trigger magnet, the processing unit confirms the separation of the bolt body 12 from the latch arm 43 based on the signal change of the reed switch 14.
[0058] When locking is required, the motor 31 reverses, causing the gear set 33 to rotate and push the push rack 32 to move relative to the lock housing 2, pulling the locking housing 41 into the notch 21. The latch arm pressing assembly 5 gradually contacts the latch arm 43, and the force of the latch arm 43 encircling the bolt body 12 gradually increases. The bolt body 12 also moves relative to the lock housing 2 under the action of the locking housing 41. When the locking housing 41 is fully retracted into the lock housing 2, the latch arm pressing assembly 5 contacts the latch arm 43. The latch arm 43 encircles the bolt body 12 under the action of the limiting member 42 and the pressing spring 53. At this time, the bolt body 12 is located inside the lock housing 2, completing the locking action. After the reed switch 14 approaches the trigger magnet, the processing unit confirms that the bolt body 12 and the latch arm 43 have made contact based on the signal change of the reed switch 14.
[0059] The beneficial effects of this utility model are:
