Description

Technical Field

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

[0002] As a security product that integrates electronic technology and mechanical structure, electronic flat locks can provide security protection, convenient opening and closing, and status management for enclosed spaces such as doors, cabinets, and boxes through the combination of electronic control and mechanical execution.

[0003] In existing technologies, some smart locks with high-definition displays, fingerprint and facial recognition modules, Wi-Fi and Bluetooth modules typically require their internal electronic components to operate for extended periods and generate continuous heat. Some smart locks have corresponding heat dissipation slots on the outer shell to prevent high temperatures from affecting chip stability. However, in actual use, when the lock is in an extremely cold environment, external moisture can easily enter its interior through the heat dissipation slots, eventually condensing and freezing, making it difficult to open the lock normally. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides an active electronic flat lock that effectively solves the problem that in some existing locks used in extremely cold environments, external moisture can easily enter the lock through the heat dissipation grooves, eventually condensing and freezing, making the lock difficult to open normally.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an active electronic flat lock, including an electronic lock body, including a base, a latch adapted to be installed on the outer surface of the base, a handle rotatably connected to the inner surface of the base and used in conjunction with the latch, a card swiping area fixedly installed on the outer surface of the base, an LED indicator light set below the card swiping area, and a heat dissipation vent opened on the outer surface of the base.

[0007] The protective mechanism includes an opening and closing component for controlling the opening or closing of the heat dissipation vent, and a drive component that can automatically control the opening and closing component to close the heat dissipation vent in extremely cold weather.

[0008] The opening and closing component is disposed outside the heat dissipation port, and the driving component is disposed outside the opening and closing component;

[0009] The opening and closing assembly includes a fixed frame fixedly connected to the outer surface of the base, an arc-shaped guide rail fixedly connected to the outside of the fixed frame, and a support plate fixedly installed on the other side of the arc-shaped guide rail.

[0010] Furthermore, the opening and closing assembly also includes a plurality of rotating rods rotatably connected to the inner surface of the support plate, and a sealing plate fixedly sleeved on the outer surface of the rotating rods for sealing the heat dissipation vent.

[0011] Furthermore, the driving assembly includes a fixing block fixedly connected to the outer surface of the base, a heat-conducting sleeve hinged to the outer surface of the fixing block, and a thermal expansion block disposed in the inner cavity of the heat-conducting sleeve.

[0012] Furthermore, the thermal expansion block is located at the inner wall end of the heat-conducting sleeve, which can absorb the heat of the electronic components inside the base and undergo expansion and elastic deformation, and can shrink and recover when the external temperature of the base decreases.

[0013] Furthermore, the drive assembly also includes a driven rod disposed on the outer end face of the thermal expansion block, an arc-shaped plate hinged to the through end of the driven rod, and a plurality of pressure grooves formed on the outer surface of the arc-shaped plate.

[0014] Furthermore, the outer surface of the driven rod slides in contact with the inner wall of the heat-conducting sleeve, and the outer surface of the arc-shaped plate slides in contact with the inner wall of the arc-shaped guide rail.

[0015] Furthermore, the drive assembly also includes a force-bearing column movably connected to the inner wall of the pressure groove, a swing block fixedly sleeved on the outer surface of the force-bearing column and used in conjunction with the sealing plate, and a spring sleeved on the outside of the driven rod.

[0016] Furthermore, the swing block is fixedly connected to the outer surface of the sealing plate, the spring is fixedly installed on the inner wall of the heat-conducting sleeve, and its other end is fixedly connected to the outer surface of the driven rod;

[0017] When the arc-shaped plate slides along the inner wall of the arc-shaped guide rail, it can squeeze the force-bearing column through the pressure groove, thereby causing the force-bearing column to drive the sealing plate to rotate around the rotating rod through the swing block.

[0018] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0019] This invention, by setting up a protective mechanism, can not only automatically seal the heat dissipation vents when the electronic lock body is in an extremely cold environment, preventing external moisture from entering the base through the vents and condensing into ice, but also automatically restore the heat dissipation function of the vents when the electronic lock body is at normal temperature or high temperature, ensuring that the heat generated by the long-term operation of the electronic components inside the base is dissipated in a timely manner. This achieves the effect of ensuring the stable operation of the electronic lock body in different temperature scenarios while extending its service life. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example: An active electronic planar lock, see attached diagram. Figure 1 -Appendix Figure 6 ,include,

[0031] The electronic lock body 100 includes a base 110, a latch 120 adapted to be installed on the outer surface of the base 110, a handle 130 rotatably connected to the inner surface of the base 110 and used in conjunction with the latch 120, a card swiping area 140 fixedly installed on the outer surface of the base 110, an LED indicator 150 provided below the card swiping area 140, and a heat dissipation vent 160 opened on the outer surface of the base 110.

[0032] It should be noted that the base 110 is used to support all sub-components such as the latch 120, handle 130, and card swiping area 140, and provides installation space for its internal electronic components, such as the card recognition module and control chip. At the same time, the heat inside the base 110 is naturally dissipated through the heat dissipation vent 160 to prevent the stability of electronic components from being affected by high temperature. After the authorization verification in the card swiping area 140 is passed, the latch 120 can be driven to extend and retract by the internal transmission mechanism to complete the switching between locked and unlocked states. The handle 130 provides a mechanical operation interface for the user. In the unlocked state, the user can directly drive the latch 120 to extend and retract by turning the handle 130. The card swiping area 140 is used for electronic authorization verification. When the user swipes the card, the card information can be read by its internal recognition module and transmitted to the control chip to complete the authorization verification. If the verification is successful, the unlocking command is triggered. The LED indicator 150 can provide feedback on the working status of the electronic lock body 100 through the light color and flashing status, thereby providing intuitive operation guidance for the user.

[0033] The protective mechanism 200 includes an opening and closing component 210 for controlling the opening or closing of the heat dissipation vent 160, and a drive component 220 that can automatically control the opening and closing component 210 to close the heat dissipation vent 160 in extremely cold weather.

[0034] The opening and closing component 210 is disposed outside the heat dissipation port 160, and the driving component 220 is disposed outside the opening and closing component 210;

[0035] The opening and closing assembly 210 includes a fixed frame 211 fixedly connected to the outer surface of the base 110, an arc-shaped guide rail 212 fixedly connected to the outside of the fixed frame 211, and a support plate 213 fixedly installed on the other side of the arc-shaped guide rail 212.

[0036] Specifically, the opening and closing assembly 210 also includes a plurality of rotating rods 214 rotatably connected to the inner surface of the support plate 213, and a sealing plate 215 fixedly sleeved on the outer surface of the rotating rods 214 for sealing the heat dissipation port 160.

[0037] It should be noted that the fixing bracket 211 is used to provide stable support for the arc-shaped guide rail 212, the support plate 213 is used to install the rotating rod 214, the rotating rod 214 is used to provide a fixed fulcrum for the rotation of the sealing plate 215, and the sealing plate 215 is a protective component covering the heat dissipation port 160. Its outer contour matches the heat dissipation port 160. When rotated to the closed position, it can completely block the heat dissipation port 160 to prevent external moisture from entering. When rotated to the open position, it can expose the heat dissipation port 160 to ensure the heat dissipation function.

[0038] Furthermore, the drive assembly 220 includes a fixing block 221 fixedly connected to the outer surface of the base 110, a heat-conducting sleeve 222 hinged to the outer surface of the fixing block 221, and a thermal expansion block 223 disposed in the inner cavity of the heat-conducting sleeve 222.

[0039] Preferably, the thermal expansion block 223 is located at the end of the inner wall of the heat-conducting sleeve 222. It can absorb the heat of the electronic components inside the base 110 and undergo expansion and elastic deformation, and can shrink and recover when the external temperature of the base 110 decreases.

[0040] It should be noted that the drive assembly 220 also includes a driven rod 224 disposed on the outer end face of the thermal expansion block 223, an arc-shaped plate 225 hinged to the through end of the driven rod 224, and a plurality of pressure grooves 226 formed on the outer surface of the arc-shaped plate 225.

[0041] Furthermore, the outer surface of the driven rod 224 slides in contact with the inner wall of the heat-conducting sleeve 222, and the outer surface of the arc plate 225 slides in contact with the inner wall of the arc guide rail 212.

[0042] Specifically, the drive assembly 220 also includes a force-bearing column 227 movably connected to the inner wall of the pressure groove 226, a swing block 228 fixedly sleeved on the outer surface of the force-bearing column 227 and used in conjunction with the sealing plate 215, and a spring 229 sleeved on the outside of the driven rod 224.

[0043] It should be noted that the fixing block 221 is fixedly connected to the outer surface of the base 110, providing mounting support for the drive assembly 220. The heat-conducting sleeve 222 is used to conduct the heat generated by the electronic components inside the base 110 to the thermal expansion block 223 and provide sliding guidance for the driven rod 224. The thermal expansion block 223 can absorb the heat inside the base 110 and undergo expansion and elastic deformation at room temperature or high temperature, pushing the driven rod 224 to maintain its outward extension posture. The thermal expansion block 223 can also be extremely In cold environments, when the outside temperature drops suddenly, the mechanism contracts and recovers. In conjunction with the spring 229 pulling the driven rod 224, it maintains the inward contraction posture. When the heated expansion block 223 expands, the driven rod 224 can push the arc plate 225 to slide along the inner wall of the arc guide rail 212. Then, through the cooperation of the arc plate 225 and multiple pressure grooves 226, multiple force-bearing columns 227 are pushed at the same time. The force-bearing columns 227 then drive the swing block 228 and the sealing plate 215 to rotate around the rotating rod 214, thereby opening the heat dissipation port 160.

[0044] Preferably, the swing block 228 is fixedly connected to the outer surface of the sealing plate 215, the spring 229 is fixedly installed on the inner wall of the heat-conducting sleeve 222, and its other end is fixedly connected to the outer surface of the driven rod 224.

[0045] When the arc plate 225 slides along the inner wall of the arc guide rail 212, it can squeeze the force column 227 through the pressure groove 226, so that the force column 227 drives the sealing plate 215 to rotate around the rotating rod 214 through the swing block 228.

[0046] When using,

[0047] In the initial state: The heat generated by the electronic components inside the base 110 during operation is naturally dissipated through the heat dissipation port 160. At this time, the heat inside the base 110 is conducted to the thermal expansion block 223 through the heat-conducting sleeve 222, causing the thermal expansion block 223 to expand and push the driven rod 224 to maintain its outward extension posture. Then, the driven rod 224 drives the arc plate 225 to slide along the arc guide rail 212, so that the arc plate 225 squeezes the force column 227 through the pressure groove 226. Then, through the cooperation of the force column 227 and the swing block 228, the sealing plate 215 is driven to rotate around the rotating rod 214, ultimately keeping the sealing plate 215 open and ensuring the heat dissipation efficiency of the heat dissipation port 160.

[0048] In extremely cold weather: When the outside temperature drops sharply, the thermal expansion block 223 contracts due to the cold. At this time, the reaction force of the spring 229 pulls the driven rod 224 to reset, thereby causing the arc plate 225 to slide in the opposite direction. Then, through the cooperation of the arc plate 225 and the pressure groove 226, the force column 227 is squeezed in the opposite direction. This causes the force column 227 to rotate through the swing block 228 to seal the position of the heat dissipation port 160, thereby preventing external moisture from entering the base 110 and freezing.

[0049] When a user needs to unlock the door: place the card close to the card reader 140, the internal identification module reads the information and transmits it to the control chip. After successful verification, an unlocking command is triggered. The lock tongue 120 is driven to retract by the transmission mechanism, and the LED indicator 150 flashes green to indicate successful unlocking. The user can rotate the handle 130 to assist in opening and closing.

[0050] In summary, by setting up the protective mechanism 200, not only can the heat dissipation vent 160 be automatically sealed when the electronic lock body 100 is in an extremely cold operating environment, preventing external moisture from entering the base 110 through the heat dissipation vent 160 and condensing into ice, but it can also automatically restore the heat dissipation function of the heat dissipation vent 160 when the electronic lock body 100 is at normal temperature or high temperature, ensuring that the heat generated by the long-term operation of the electronic components inside the base 110 is dissipated in a timely manner. This achieves the effect of ensuring the stable operation of the electronic lock body 100 under different temperature scenarios while extending its service life.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
