Description

Technical Field

[0001] This utility model relates to the field of packaging protection technology, and in particular to a packaging structure for smart door locks. Background Technology

[0002] With the rapid development of the smart home industry, smart door locks, as core products for home security, are becoming increasingly complex in structure. They typically include multiple components such as the door lock body (including touch panel, fingerprint recognition module, motor drive components), lock body, emergency key, installation accessory package (screws, expansion tubes, instruction manual, etc.) and charging equipment.

[0003] Existing technologies, such as the utility model patent with publication number CN 113525926 B, disclose a packaging structure for a smart door lock, including: an upper packaging component and a lower packaging component that are fastened together. The lower packaging component has a first receiving groove, and the upper packaging component has a corresponding second receiving groove on its wall facing the lower packaging component. The first and second receiving grooves form a receiving cavity for installing the product to be packaged. Both the upper and lower packaging components are made of cushioning material. In summary, the design of this application can achieve rapid assembly and effectively reduce damage caused by vibration and impact during product transportation; furthermore, it can minimize the size of the cushioning structure while ensuring structural strength, reducing the consumption of packaging materials and effectively saving packaging production costs while protecting the product.

[0004] Existing technical solutions rely on the cushioning properties of foam and other materials during use, and do not design active shock absorption structures for high-frequency vibration and impact scenarios during transportation. When encountering bumpy road conditions, relative displacement can easily occur between the door lock body and the inner lining, leading to problems such as touch screen breakage and poor fingerprint module contact.

[0005] To address the aforementioned problems, this utility model provides a packaging structure for smart door locks. Utility Model Content

[0006] The purpose of this utility model is to solve the problems of insufficient shock absorption and protection in the existing smart door lock packaging, which leads to touch screen breakage and poor fingerprint module contact, and to propose a packaging structure for smart door locks.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a packaging structure for a smart door lock, comprising a smart door lock, a protective packaging mechanism, and a top fixing mechanism, wherein the smart door lock is snapped into the interior of the protective packaging mechanism, and the top fixing mechanism is snapped into the top of the protective packaging mechanism, and the protective packaging mechanism comprises an internal soft packaging component and an external stable protective component.

[0008] The internal soft packaging assembly includes a bottom snap-fit ​​foam frame and a top snap-fit ​​foam cover, and the external stabilizing protection assembly includes a shock-absorbing damper and a reset snap-fit ​​spring.

[0009] The bottom snap-fit ​​foam frame has a door lock placement slot inside, and the smart door lock is snapped into the door lock placement slot. The bottom snap-fit ​​foam frame and the top snap-fit ​​foam cover are symmetrically snapped into the outer surface of the smart door lock. The outer surface of the bottom snap-fit ​​foam frame is snapped into a placement frame. The bottom snap-fit ​​foam frame and the top snap-fit ​​foam cover are snapped into the inside of the placement frame. The placement frame is threaded to the top of the external stabilizing and protective component.

[0010] Furthermore, the external stabilization and protection component includes an external protective frame fixedly connected to the bottom of the shock absorber, and a shock absorber extension spring is sleeved on the outer surface of the shock absorber. Multiple shock absorbers and shock absorber extension springs are equally spaced on the inner bottom wall of the external protective frame.

[0011] Furthermore, the top of the shock absorber is threaded with a connector, the placement frame is threaded to the top of the shock absorber through the connector, and the top of the outer protective frame is snapped with a sealing gasket.

[0012] Furthermore, a sealing snap block is fixedly connected to the top of the outer protective frame, and a top protective cover is snapped onto the top of the outer protective frame through the sealing snap block. A sealing snap groove is opened at the bottom of the top protective cover, and the sealing snap block snaps into the inside of the sealing snap groove.

[0013] Furthermore, sliding slots are symmetrically provided at the top edges of the top protective cover and the top of the outer protective frame, and a fixing block is fixedly connected to the inner wall of the top protective cover, and the reset snap spring is fixedly connected to both sides of the fixing block.

[0014] Furthermore, an L-shaped sliding block is fixedly connected to the other end of the reset latching spring. The L-shaped sliding block and the reset latching spring are symmetrically arranged on both sides of the fixed block, and the L-shaped sliding block and the fixed block are symmetrically arranged on the top of the top protective cover.

[0015] Furthermore, the top fixing mechanism includes an adjuster that is symmetrically threaded to the top protective cover. The bottom of the adjuster is rotatably connected to a rotating bearing, and a pressing positioning plate is fixedly connected to the outer surface of the rotating bearing. The adjuster is rotatably connected to the top of the pressing positioning plate through the rotating bearing.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] In this invention, the combination of a bottom-mounted foam frame, a shock-absorbing damper, and a pressing positioning plate, along with the shock-absorbing damper and the shock-absorbing telescopic spring, absorbs impact energy during transportation. Combined with the double buffering of the internal soft packaging component's EPP foam, this reduces the relative displacement of the door lock body under high-frequency vibration and impact conditions, lowering the transportation loss rate. The outer protective frame, the sealing gasket of the top protective cover, and the sealing snap-fit ​​block form a triple-sealing structure, enhancing waterproof and moisture-proof capabilities. This allows it to adapt to harsh environments such as high-humidity coastal storage and cross-border shipping. Simultaneously, the sealing structure effectively prevents dust from entering, ensuring the product's cleanliness during final display. The L-shaped sliding snap-fit ​​block and reset snap-fit ​​spring design of the top protective cover enable quick opening. The adjuster of the top fixing mechanism allows for precise adjustment of the pressing positioning plate height, adapting to door locks of different thicknesses. This simple operation further enhances safety during handling. Attached Figure Description

[0026] Please see Figure 1-6 This utility model provides a technical solution: a packaging structure for a smart door lock, including a smart door lock 1, a protective packaging mechanism 2 and a top fixing mechanism 3. The smart door lock 1 is snapped into the inside of the protective packaging mechanism 2, and the top fixing mechanism 3 is snapped into the top of the protective packaging mechanism 2. The protective packaging mechanism 2 includes an inner soft packaging component 21 and an outer stable protective component 22.

[0027] The specific setup and function of its protective packaging mechanism 2 and top fixing mechanism 3 will be explained below.

[0028] In this embodiment: the inner soft packaging component 21 includes a bottom snap-fit ​​foam frame 211 and a top snap-fit ​​foam cover 212, and the outer stabilizing protection component 22 includes a shock absorber 221 and a reset snap-fit ​​spring 222.

[0029] The bottom snap-fit ​​foam frame 211 has a door lock placement slot 213 inside, and the smart door lock 1 is snapped into the door lock placement slot 213. The bottom snap-fit ​​foam frame 211 and the top snap-fit ​​foam cover 212 are symmetrically snapped into the outer surface of the smart door lock 1. The outer surface of the bottom snap-fit ​​foam frame 211 is snapped into a placement frame 214. The bottom snap-fit ​​foam frame 211 and the top snap-fit ​​foam cover 212 are snapped into the interior of the placement frame 214. The placement frame 214 is threaded to the top of the external stabilizing and protective component 22.

[0030] The effects achieved by the above components are as follows: the bottom snap-fit ​​foam frame 211 and the top snap-fit ​​foam cover 212 of the inner soft packaging component 21 are symmetrically snapped onto the outer surface of the smart door lock 1. The door lock body is initially positioned through the door lock placement slot 213. The foam material can buffer slight vibrations and prevent the door lock from directly contacting the hard shell components and causing scratches. The placement frame 214 forms an outer layer to wrap the bottom snap-fit ​​foam frame 211 and the top snap-fit ​​foam cover 212. On the one hand, it enhances the overall structural stability of the inner soft packaging component 21 and prevents the foam frame from shifting or deforming during transportation. On the other hand, the snap-fit ​​structure simplifies the disassembly and assembly process of the foam frame and provides a regular installation benchmark for subsequent connection with the external stable protection component 22, ensuring the assembly accuracy of the packaging structure.

[0031] Specifically, the external stabilization and protection component 22 includes an external protective frame 223 fixedly connected to the bottom of the shock absorber 221, and a shock absorber extension spring 224 is sleeved on the outer surface of the shock absorber 221. Multiple shock absorbers 221 and shock absorber extension springs 224 are equally spaced on the inner bottom wall of the external protective frame 223.

[0032] The effects achieved by the above components are as follows: the outer protective frame 223 provides an outer rigid support for the entire packaging structure, preventing external impacts from directly affecting the inner door lock; the combination of the shock absorber 221 and the shock absorber extension spring 224 forms a dual shock absorption system of damping and spring; the multiple shock absorber units set at equal intervals can evenly distribute the pressure and vibration transmitted by the frame 214; when encountering transportation bumps or external impacts, the shock absorber extension spring 224 first absorbs part of the impact energy through elastic deformation, initially reducing the vibration amplitude; the shock absorber 221 then suppresses the high-frequency rebound of the spring through hydraulic damping, preventing the door lock from shaking again due to repeated spring vibrations; the two work together to reduce the vibration intensity transmitted to the smart door lock 1, effectively protecting the fingerprint module, touch screen and other precision components inside the door lock, and reducing the transportation loss rate.

[0033] Specifically, the top of the shock absorber 221 is threaded with a connector 225, the placement frame 214 is threaded to the top of the shock absorber 221 through the connector 225, and the top of the outer protective frame 223 is snapped with a sealing gasket 226.

[0034] The effects achieved by the above components are as follows: The top of the shock absorber 221 is threadedly connected to the placement frame 214 via the connector 225. On the one hand, this enables a detachable connection between the internal soft packaging component 21 and the external stable protection component 22, facilitating individual replacement of different damaged components and reducing maintenance costs. At the same time, the detachability of the threaded connection also supports the reuse of the packaging structure. On the other hand, the tightness of the threaded connection ensures that there is no relative displacement between the placement frame 214 and the shock absorber 221, guaranteeing the stable protection effect of the shock absorption system on the internal door lock. The sealing gasket 226 on the top of the external protective frame 223 fills the gap between the protective frame and the cover when the top protective cover 228 is closed, preventing external dust and moisture from entering the packaging, avoiding moisture and rust on the door lock surface or short circuit of the circuit board due to moisture, and improving the sealing and moisture-proof performance of the packaging.

[0035] Specifically, a sealing snap block 227 is fixedly connected to the top of the outer protective frame 223, and a top protective cover 228 is snapped onto the top of the outer protective frame 223 via the sealing snap block 227. A sealing snap groove 229 is provided at the bottom of the top protective cover 228, and the sealing snap block 227 is snapped into the inside of the sealing snap groove 229.

[0036] The effects achieved by the above components are as follows: the sealing snap block 227 at the top of the outer protective frame 223 and the sealing snap groove 229 at the bottom of the top protective cover 228 form a precise snap-fit. On the one hand, the mechanical snap-fit ​​structure enhances the connection stability between the top protective cover 228 and the outer protective frame 223, preventing the cover from falling off due to bumps during transportation and ensuring the sealing of the packaging. On the other hand, the snap-fit ​​structure can further compress the top sealing gasket 226, allowing the sealing gasket 226 to fully fill the gaps and improve the sealing effect. At the same time, the trapezoidal sealing snap block 227 facilitates the alignment and installation of the cover, reduces the assembly difficulty, and improves the efficiency of packaging operations.

[0037] Specifically, sliding slots 2291 are symmetrically provided at the top edges of the top protective cover 228 and the outer protective frame 223. A fixing block 2292 is fixedly connected to the inner wall of the top protective cover 228, and a reset snap spring 222 is fixedly connected to both sides of the fixing block 2292.

[0038] The effects achieved by the above components are as follows: the sliding groove 2291 on the edge of the top protective cover 228 and the outer protective frame 223 provides a sliding track for the L-shaped sliding block 2293, and the fixing block 2292 provides a fixed support point for the reset locking spring 222. The reset locking spring 222 pushes the L-shaped sliding block 2293 into the sliding groove 2291 through its own elastic force, so that the block and the groove form a stable engagement, further locking the connection between the top protective cover 228 and the outer protective frame 223, preventing the cover from being accidentally opened during transportation. At the same time, the elasticity of the spring also provides convenience for opening the cover. Simply press the L-shaped sliding block 2293 to compress the spring and make the block disengage from the groove without the need for tools, thus improving the user's operating experience.

[0039] Specifically, the other end of the reset latching spring 222 is fixedly connected to an L-shaped sliding latch 2293. The L-shaped sliding latch 2293 and the reset latching spring 222 are symmetrically arranged on both sides of the fixed block 2292, and the L-shaped sliding latch 2293 and the fixed block 2292 are symmetrically arranged on the top of the top protective cover 228.

[0040] The effects achieved by the above components are as follows: The symmetrical arrangement of the L-shaped sliding block 2293 and the reset locking spring 222 on both sides of the fixed block 2292 and the top of the top protective cover 228 can make the locking force evenly distributed on the connection edge between the cover and the protective frame, avoiding the cover tilting or locking loosening due to uneven force on one side, ensuring the stability of the locking structure. At the same time, the symmetrical structure makes it easy for users to press the block to open the cover from any position on the side or top of the packaging, making the operation more flexible and further improving the convenience of packaging use, especially suitable for one-handed operation scenarios.

[0041] Specifically, the top fixing mechanism 3 includes an adjuster 31 that is symmetrically threaded to the top protective cover 228. The bottom of the adjuster 31 is rotatably connected to a rotating bearing 32. The outer surface of the rotating bearing 32 is fixedly connected to a pressing positioning plate 33. The adjuster 31 is rotatably connected to the top of the pressing positioning plate 33 through the rotating bearing 32.

[0042] The effects achieved by the above components are as follows: The threaded connection between the adjuster 31 and the top protective cover 228 allows the adjuster 31 to move up and down by rotation, thereby causing the pressing positioning plate 33 to move closer to or away from the top of the smart door lock 1, adapting to door lock bodies of different thicknesses. The setting of the rotating bearing 32 can prevent the pressing positioning plate 33 from rotating synchronously when the adjuster 31 rotates, preventing the pressing positioning plate 33 from rubbing against the top of the door lock, protecting the surface coating of the door lock or the touch screen. The pressing positioning plate 33, through its synergistic effect with the bottom snap-fit ​​foam frame 211, applies stable pressure from the top of the door lock, firmly fixing the door lock inside the packaging, preventing the door lock from shifting or deforming due to the pressure of the upper packaging when stacked for storage. At the same time, the transparent pressing positioning plate 33 also allows users to observe the condition of the top of the door lock without opening the packaging, confirming the integrity of the product.

[0043] Working principle: First, the smart door lock 1 is inserted into the door lock placement groove 213 of the bottom foam frame 211. The groove structure of the foam frame matches the outline of the door lock, achieving initial positioning. Then, the top foam cover 212 is aligned with the top of the door lock and snapped in. The foam material covers the upper and lower surfaces of the door lock, buffering minor vibrations and preventing scratches. Then, the assembled foam frame and door lock are inserted into the placement frame 214. The outer layer of the placement frame 214 enhances the stability of the internal structure, completing the initial protection and positioning of the door lock.

[0044] The placement frame 214 is threadedly connected to the damping damper 221 on the inner bottom wall of the outer protective frame 223 via the connector 225, ensuring that the placement frame 214 and the damping unit are firmly fixed. At this time, the damping extension spring 224 outside the damping damper 221 is in a natural state, preparing for subsequent damping. The outer protective frame 223 forms an outer rigid protection to block external impacts.

[0045] Cover the top protective cover 228, so that the sealing snap block 227 on the top of the outer protective frame 223 snaps into the sealing snap groove 229 at the bottom of the top protective cover 228. At the same time, the reset snap spring 222 on the inner wall of the top protective cover 228 pushes the L-shaped sliding snap block 2293 into the sliding snap groove 2291, realizing the double locking of the cover. At this time, the sealing gasket 226 on the top of the outer protective frame 223 is compressed, filling the gap between the cover and the protective frame, completing the seal. Finally, rotate the adjuster 31 of the top fixing mechanism 3, and drive the pressing positioning plate 33 to move downward through the rotating bearing 32 until the pressing positioning plate 33 is attached to the top of the smart door lock 1, realizing the top fixing of the door lock and preventing displacement.

[0046] During transportation, if bumps or impacts occur, the outer protective frame 223 first blocks part of the external force, and the remaining vibration is absorbed by the damping and spring synergy of the shock absorber 221 and the shock absorber extension spring 224, preventing the vibration from being transmitted to the inner door lock. The sealing structure continuously blocks dust and moisture from entering, protecting the door lock components from moisture. The top pressing positioning plate 33 and the bottom foam frame work together to ensure that the door lock will not be deformed or shifted due to pressure when stacked for storage.

[0047] When it is necessary to remove the door lock, simply press the L-shaped sliding block 2293 on the top protective cover 228 to compress the reset locking spring 222 and disengage the block from the sliding slot 2291. This will open the top protective cover 228. Rotate the adjuster 31 in the opposite direction to move the pressing positioning plate 33 upward and disengage it from the top of the door lock. Then, remove the connecting piece 225 between the placement frame 214 and the shock absorber 221, remove the placement frame 214, and finally open the top locking foam cover 212. The door lock can then be removed from the bottom locking foam frame 211. The entire process is tool-free and easy to operate.
