[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] Reference Figures 1 to 7 The utility model proposes a rechargeable intelligent door lock, comprising: an oblique lock tongue 1, a lock tongue fixing frame 2, a charging electrode 103, a charging interface mechanism 3, an insulating mechanism 104, and a door lock charging device;
[0038] The charging electrode 103 is embedded in the oblique lock tongue 1, and an insulating mechanism 104 is provided between the charging electrode 103 and the oblique lock tongue 1; the charging electrode 103 and the oblique lock tongue 1 are electrically connected to the door lock charging device respectively; in some embodiments, the charging electrode 103 and the insulating mechanism 104 can be configured to be detachably installed on the side of the oblique lock tongue 1. To ensure that the oblique lock tongue can smoothly enter the lock tongue fixing frame when closing the door, the surface of the charging electrode 103 and the insulating mechanism 104 on the oblique lock tongue 1 is kept flat.
[0039] The charging interface mechanism 3 is arranged on the lock tongue fixing frame 2; the charging interface mechanism 3 includes an elastic positive connection point 3011 and an elastic negative connection point 3021; when the door is closed, the oblique lock tongue 1 automatically enters the lock tongue fixing frame 2, and the oblique lock tongue 1 automatically enters the lock tongue fixing frame 2, so that the charging interface mechanism 3 clamps the oblique lock tongue 1 and the charging electrode 103; in some embodiments, the elastic positive connection point 3011 contacts the charging electrode 103, and the elastic negative connection point 3021 contacts the oblique lock tongue 1 (the oblique lock tongue serves as the negative input port of the door lock charging device).
[0040] The charging interface mechanism 3 is connected to the power supply end.
[0041] Based on this solution, a charging electrode is embedded on an inclined lock tongue and electrically isolated from the inclined lock tongue by an insulating mechanism, and the charging electrode and the inclined lock tongue are electrically connected to the door lock charging device respectively; a charging interface mechanism is provided on a lock tongue fixing frame installed on the door frame side, and when the door is closed, the inclined lock tongue automatically enters the lock tongue fixing frame, so that the charging interface mechanism clamps the inclined lock tongue and the charging electrode, and the charging interface mechanism is connected to the power supply end, thereby forming a charging circuit for the smart door lock; the problem of inconvenience caused by the need to replace batteries in the prior art is solved.
[0042] It is understandable that the advantage of configuring the charging electrode piece on the oblique lock tongue over configuring the charging electrode piece on the square lock tongue (which needs to be locked and turned by the key before it pops out from the lock body and enters the lock tongue fixing frame) is that the charging electrode piece is configured on the oblique lock tongue, and charging can be performed as long as the door is closed, without the need to lock and turn the key before it pops out from the lock body and enters the lock tongue fixing frame to charge the door lock. In addition, in the invention, only a charging electrode piece needs to be embedded in the oblique lock tongue, and the charging electrode piece and the oblique lock tongue are isolated by an insulating mechanism, and the charging electrode piece and the oblique lock tongue are used as the negative input port of the door lock charging device, so that the charging contact surface is expanded, and the charging interface mechanism is used to clamp the oblique lock tongue and the charging electrode piece, thereby improving the contact reliability of charging.
[0043] refer to Figure 1 In one embodiment, the charging electrode is embedded in the side arc surface 101 of the oblique lock tongue. Figure 1 The oblique lock tongue has two oblique lock tongue side arc surfaces 101. Figure 1 The figure shows one of them, and the other is on the corresponding back side; an insulating mechanism 104 is provided between the charging electrode 103 and the oblique lock tongue 1, forming a flat surface on the side arc surface 101 of the oblique lock tongue.
[0044] In this solution, flatness means keeping flat with the curve of the side arc surface of the oblique lock tongue, so that the charging electrode piece 103 and the insulating mechanism 104 of 6JP231007 will not protrude or sink on the side arc surface of the oblique lock tongue. The charging electrode piece 103 and the insulating mechanism 104 are both configured to be detachably mounted on the side arc surface of the oblique lock tongue 1.
[0045] Based on this solution, the charging electrode 103 is arranged on the side arc surface 101 of the inclined locking tongue, which can increase the contact surface of the charging end and improve the charging reliability.
[0046] In one embodiment, reference Figure 5 , Figure 7The charging interface mechanism 3 includes a positive elastic sheet 301 and a negative elastic sheet 302. The positive elastic sheet 301 is provided with an elastic positive connection point 3011, and the negative elastic sheet 302 is provided with an elastic negative connection point 3021. The positive elastic sheet 301 and the negative elastic sheet 302 are arranged to be inclined toward each other to form a gap, and the gap is located in the lock tongue fixing frame. When closing the door, the oblique lock tongue 1 automatically enters the lock tongue fixing frame 2 to enter the gap, so that the positive elastic sheet and the negative elastic sheet clamp and contact the charging electrode sheet and the oblique lock tongue. The positive elastic sheet (elastic positive connection point 3011) contacts the charging electrode sheet, and the negative elastic sheet (elastic negative connection point 3021) contacts the oblique lock tongue.
[0047] Figure 7 It is only a schematic diagram, and the positions of the positive elastic sheet and the negative elastic sheet change accordingly according to the position of the charging electrode sheet on the oblique locking tongue.
[0048] Based on this solution, the positive elastic sheet and the negative elastic sheet form an elastic gap so that when the door is closed, the oblique lock tongue enters the gap, so that the elastic positive connection point and the elastic negative connection point are in full contact with the oblique lock tongue and the charging electrode sheet to ensure charging reliability.
[0049] In one embodiment, reference Figure 5 , Figure 7 The positive elastic sheet 301 is provided with an elastic positive connection point 3011 at one end, and the negative elastic sheet 302 is provided with an elastic negative connection point 3021 at one end. Based on this solution, when closing the door, it is convenient for the oblique lock tongue to enter the gap. Figure 5 The positions of the positive electrode elastic sheet and the negative electrode elastic sheet shown can be adjusted according to needs and are not limited to the positions shown in the figure.
[0050] In one embodiment, reference Figure 2 The charging electrode piece 103 is embedded in the oblique lock tongue side plane 102, and an insulating mechanism 104 is provided between the charging electrode piece 103 and the oblique lock tongue 1, forming a flat surface on the oblique lock tongue side plane 102. Based on this scheme, the charging electrode piece is provided on the side plane of the oblique lock tongue, which can increase the contact surface of the charging end and improve the charging reliability. The charging electrode piece 103 and the insulating mechanism 104 are both configured to be detachably installed on the side plane of the oblique lock tongue 1.
[0051] Flatness refers to keeping it flat with the side plane of the oblique lock tongue, so that the charging electrode piece 103 and the insulating mechanism 104 will not protrude or sink from the side plane of the oblique lock tongue. The charging electrode piece 103 and the insulating mechanism 104 are both configured to be detachably mounted on the side plane of the oblique lock tongue 1.
[0052] When the charging electrode 103 is embedded in the Figure 2 When the side plane 102 of the locking tongue is obliquely shown, the schematic diagram of the charging interface mechanism is as follows Figure 6The setting angles of the negative elastic sheet 302 and the positive elastic sheet 301 are adapted to the shape of the oblique locking tongue, and an outward bending section is provided on the port side of the negative elastic sheet 302 and the positive elastic sheet 301 to facilitate contact with the oblique locking tongue for charging.
[0053] In some embodiments, the charging electrode 103 can also be arranged at Figure 1 An insulating mechanism 104 is provided between the charging electrode 103 and the oblique lock tongue 1 to form a flat surface on the oblique lock tongue positive arc surface 105.
[0054] Flatness means keeping it flat with the positive arc surface of the oblique lock tongue, so that the charging pole piece 103 and the insulating mechanism 104 will not protrude or sink on the positive arc surface of the oblique lock tongue. The charging pole piece 103 and the insulating mechanism 104 are both configured to be detachably mounted on the positive arc surface of the oblique lock tongue 1.
[0055] In some embodiments, the oblique lock tongue or charging electrode can be configured to have a damping less than that of leaving the lock tongue fixing frame when entering the lock tongue fixing frame, so that when the charging interface mechanism clamps the oblique lock tongue and the charging electrode, the oblique lock tongue is not easy to rebound and disengage, thereby improving charging reliability.
[0056] In one embodiment, the rechargeable smart door lock further includes a driving device and a lock tongue detection device;
[0057] When the lock tongue detection device detects that the lock tongue enters the lock tongue fixing frame, the driving device drives the positive elastic sheet and the negative elastic sheet of the charging interface mechanism to contact the oblique lock tongue and the charging electrode sheet; when the lock tongue detection device detects that the lock tongue leaves the lock tongue fixing frame, the driving device drives the positive elastic sheet and the negative elastic sheet of the charging interface mechanism to release the contact with the oblique lock tongue and the charging electrode sheet.
[0058] In another embodiment, the rechargeable smart door lock further includes a driving device and a door closing detection device; when the door closing detection device detects that the door is closed, the driving device drives the positive elastic sheet and the negative elastic sheet of the charging interface mechanism to contact the oblique lock tongue and the charging electrode; when the door closing detection device detects that the door is opened, the driving device drives the positive elastic sheet and the negative elastic sheet of the charging interface mechanism to release the contact with the oblique lock tongue and the charging electrode. The door closing detection device detects that the door is opened, which is not limited to the final state of the door opening, but also includes the intention of opening the door and the process of opening the door.
[0059] The lock tongue detection device may be configured as an image sensor, which recognizes through images whether the oblique lock tongue enters the lock tongue fixing frame.
[0060] In some embodiments, the door closing detection device can be configured as:
[0061] 1. Sensor detection
[0062] By installing sensors on the door, the state changes of the door can be monitored in real time. Contact switch sensors (such as micro switches, push button switches, etc.) and non-contact sensors (such as infrared sensors, ultrasonic sensors, etc.) can be used. When the door is opened or closed, the sensor will send a signal to the drive device, thereby realizing the open and closed state detection of the door.
[0063] 2. Visual inspection
[0064] Visual inspection is to capture the image of the door through the camera and realize the door status detection through image processing technology. Set markers on the door, such as color blocks, barcodes, etc., so that the image recognition algorithm can accurately identify the door status. It can realize the detection and recognition of multiple targets at the same time.
[0065] 3. Sound detection
[0066] Sound detection is to capture the sound made when the door is opened and closed through the sound sensor to determine the state of the door. This method is suitable for situations where the ambient noise is small. It is easy to install and does not require additional equipment to be installed on the door.
[0067] 4. Magnetic detection
[0068] Magnetic detection is to judge the state of the door by detecting the change of magnetic force on the door. Install magnets and magnetic sensors on the door. When the door is opened or closed, the magnetic sensor will detect the change of magnetic force and send a signal to the drive device. It has high sensitivity and accuracy.
[0069] 5. Infrared detection
[0070] Infrared detection is to judge the state of the door by detecting the change of infrared radiation on the door. When the door is opened or closed, the infrared radiation will change, and the infrared sensor will capture this change and send a signal to the drive device. It can be used in a dimly lit environment.
[0071] 6. Microwave detection
[0072] Microwave detection is to determine the state of the door by emitting microwaves to the door and receiving the reflected microwaves. When the door is opened or closed, the reflected microwaves will change, so the state of the door can be determined. It can penetrate non-metallic objects such as glass, plastic, etc., so it is suitable for detecting doors made of these materials.
[0073] 7. Touch detection
[0074] Touch detection is to determine the state of the door by setting a touch switch or capacitive sensor on the door. When a person touches the switch or sensor, a signal will be sent to the drive device to determine the state of the door. It is easy to operate.
[0075] 8. Vibration detection
[0076] Vibration detection is to determine the state of the door by detecting the vibration on the door. Install a vibration sensor on the door, and when the door is opened or closed, it will generate vibration. The vibration sensor will detect this vibration and send a signal to the drive device. An alarm can be sounded when the door is forced to open or close.
[0077] The configuration of the above door closing detection device may require selecting a suitable detection method according to actual needs and application scenarios.
[0078] In one embodiment, the charging interface mechanism 3 is detachably arranged on the lock tongue fixing frame 2. Based on this solution, the flexibility of installing the charging interface mechanism can be improved.
[0079] In one embodiment, the charging interface mechanism 3 is connected to the power supply end through a cable or a plug-in.
