Description

Technical Field

[0001] This utility model relates to the field of charging technology for smart sliding door locks, specifically an automatic charging device for smart sliding door locks used on ships. Background Technology

[0002] Smart locks are locks that integrate advanced technology. They not only have the security of traditional mechanical locks, but also add convenience and intelligent functions. Currently, there are two power supply solutions for smart locks on the market: one is to install batteries inside the lock to power the smart lock. This solution is mostly used in the application scenario of single household entrance doors. Currently, the power supply time of common smart locks on the market is generally 6-12 months. Users will have to replace batteries frequently during the use of the lock, which will cause unnecessary trouble for users.

[0003] A smart door lock automatic charging device, disclosed in publication number CN219138690U, features a matching angled latch and lock seat installed on the openable side of the door leaf and frame. When the door is closed, the latch and lock seat form a path to charge the battery; when the door is open, the path is broken, ensuring sufficient battery power. This not only meets the expansion needs of smart door lock functions but also significantly reduces the overall cost of the door leaf, offering good versatility and a long service life. The angled latch is a conductive metal body with a metal sheet on its flat surface that is insulated from the metal body by an insulating pad, ensuring safe operation. Safety: By ensuring that the outer surface area of ​​the metal sheet occupies more than 60% of the plane area, and that the contact distance between the ends of the positive and negative spring sheets on the lock seat is less than the thickness of the oblique lock tongue, the contacts are in close contact with the oblique arc surface and the metal sheet, respectively, ensuring the reliability of charging. However, the above-mentioned automatic charging device for smart door locks has a relatively simple structure and cannot achieve automatic charging of the door lock, resulting in poor practicality and flexibility of the overall device. It also requires frequent battery replacement, which is cumbersome. Therefore, it is necessary to provide a new automatic charging device for marine sliding door smart door locks to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic charging device for a marine sliding door smart lock, which has the advantages of automatic charging to prevent the door from being unable to open due to power shortage, and solves the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic charging device for a marine sliding door smart lock, comprising: a fixed frame, the fixed frame having a cavity inside, a lock body and a fixed plate fixedly connected to the top of the fixed frame, and a charging base fixedly connected to the outside of the fixed plate; and an automatic component, the automatic component including a return spring fixedly connected to the left end of the cavity. During use, when there is sufficient power inside the lock body, the electromagnet synchronizes with the current inside the lock body, and the magnetic force is greater than the elastic force of the return spring, causing the electromagnet to attract an iron block, causing the iron block to move closer to the electromagnet, and simultaneously causing the charging component to move away from the charging base. When the power supply current inside the lock body decreases, the current and magnetic force of the electromagnet decrease synchronously, and the magnetic force is less than the elastic force of the return spring, causing the charging head to move closer to the charging base to achieve charging. During the process, no manual control is required; the charging and power-off functions are automatically adjusted according to the power level inside the lock body, making it more efficient and convenient to use.

[0006] Preferably, the automatic component further includes an iron block, which is fixedly connected to the right end of the return spring. An electromagnet is fixedly connected inside the right end of the cavity, and a charging component is fixedly connected to the top of the iron block. When there is sufficient power inside the lock body, the electromagnet synchronizes with the current inside the lock body, and the magnetic force is greater than the elastic force of the return spring, causing the electromagnet to attract the iron block, making the iron block move closer to the electromagnet, and simultaneously causing the charging component to move away from the charging base. When the power supply current inside the lock body decreases, the current and magnetic force of the electromagnet decrease simultaneously, and the magnetic force is less than the elastic force of the return spring, causing the charging head to move closer to the charging base to achieve charging.

[0007] Preferably, the electromagnet is connected to the battery inside the lock body via a wiring harness, and the charging base is connected to the lock body via a wiring harness. When the current inside the lock body decreases, the synchronous magnetic force of the electromagnet decreases.

[0008] Preferably, the charging component includes a sliding plate, and a charging head is fixedly connected to the outside of the sliding plate. After the charging head is inserted into the charging base, it can charge the lock body.

[0009] Preferably, the top of the fixed frame is provided with a sliding groove, and the sliding plate is engaged inside the sliding groove. The sliding groove can limit the sliding trajectory of the sliding plate.

[0010] Preferably, a mounting plate is fixedly connected to the bottom of the fixed frame. The mounting plate has two mounting holes inside, and screws are rotatably connected inside each of the two mounting holes. The combination of the screws and the mounting plate enables the installation of the entire device.

[0011] Preferably, both screws are fitted with limiting springs. The limiting springs are made of stainless steel. The elastic force of the limiting springs can act in the opposite direction on the screws, so that the screws will not easily loosen after being tightened.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] I. During the use of this utility model, when there is sufficient power inside the lock body, the electromagnet synchronizes with the current inside the lock body, and the magnetic force is greater than the elastic force of the return spring, causing the electromagnet to attract the iron block, making the iron block move closer to the electromagnet, and simultaneously moving the charging component away from the charging base. When the power supply current inside the lock body decreases, the current and magnetic force of the electromagnet decrease simultaneously, and the magnetic force is less than the elastic force of the return spring, causing the charging head to move closer to the charging base to achieve charging. During the process, no manual control is required, and the charging and power-off will be automatically adjusted according to the power level inside the lock body, making it more efficient and convenient to use.

[0014] II. In this utility model, the combination of screws and mounting plate enables the installation of the entire device. The elastic force of the limiting spring can act in the opposite direction on the screw, so that the screw will not easily loosen after being tightened. Attached Figure Description

During use, when there is sufficient power inside the lock body 4, the electromagnet 10 synchronizes with the current inside the lock body 4, and the magnetic force is greater than the elastic force of the return spring 11, causing the electromagnet 10 to attract the iron block 12, causing the iron block 12 to move closer to the electromagnet 10, and simultaneously causing the charging component to move away from the charging base 6. When the power supply current inside the lock body 4 decreases, the current and magnetic force of the electromagnet 10 decrease synchronously, and the magnetic force is less than the elastic force of the return spring 11, causing the charging head 9 to move closer to the charging base 6 to achieve charging. During the process, no manual control is required; the charging and power-off are automatically adjusted according to the power level inside the lock body 4, making it more efficient and convenient to use.

[0022] The automatic component also includes an iron block 12, which is fixedly connected to the right end of the return spring 11. An electromagnet 10 is fixedly connected inside the right end of the cavity 13. A charging component is fixedly connected to the top of the iron block 12. When there is enough power inside the lock body 4, the electromagnet 10 synchronizes with the current inside the lock body 4. The magnetic force is greater than the elastic force of the return spring 11, causing the electromagnet 10 to attract the iron block 12, making the iron block 12 move closer to the electromagnet 10. Simultaneously, the charging component moves away from the charging base 6. When the power supply current inside the lock body 4 decreases, the current and magnetic force of the electromagnet 10 decrease simultaneously. The magnetic force is less than the elastic force of the return spring 11, causing the charging head 9 to move closer to the charging base 6 to achieve charging.

[0023] Electromagnet 10 is connected to the battery inside lock body 4 via a wiring harness. Charging base 6 is connected to lock body 4 via a wiring harness. When the current inside lock body 4 decreases, the magnetic force of electromagnet 10 decreases synchronously.

[0026] When the automatic charging device of the intelligent door lock for the ship's sliding door is in use, when there is sufficient power inside the lock body 4, the electromagnet 10 synchronizes with the current inside the lock body 4, and the magnetic force is greater than the elastic force of the return spring 11, so that the electromagnet 10 attracts the iron block 12, causing the iron block 12 to move closer to the electromagnet 10, and simultaneously moving the charging component away from the charging base 6. When the power supply current inside the lock body 4 decreases, the current and magnetic force of the electromagnet 10 decrease simultaneously, and the magnetic force is less than the elastic force of the return spring 11, so that the charging head 9 moves closer to the charging base 6 to achieve charging.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: an automatic charging device for a marine sliding door smart door lock. The bottom of the fixed frame 2 is fixedly connected to a mounting plate 1. The mounting plate 1 has two mounting holes 14 inside. Screws 15 are rotatably connected inside the two mounting holes 14. The screws 15 and the mounting plate 1 are combined to realize the installation of the whole device.

[0028] Both screws 15 are fitted with limiting springs 8. The limiting springs 8 are made of stainless steel. The elastic force of the limiting springs 8 can act in the opposite direction on the screws 15, so that the screws 15 will not easily loosen after being tightened.

[0029] When the shipboard sliding door smart door lock automatic charging device is in use, the screw 15 and the mounting plate 1 are combined to install the whole device. The elastic force of the limit spring 8 can act on the screw 15 in the opposite direction, so that the screw 15 will not easily loosen after being tightened.
