Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, specifically to a battery slot gap compensation structure for smart locks. Background Technology

[0002] Smart locks typically rely on dry cell batteries or lithium batteries in their battery compartments for power, and the stability of this power supply directly affects the reliability of the lock's security functions. In existing smart lock battery compartment designs, variations in battery dimensions and manufacturing tolerances can lead to poor battery contact, causing power outages, malfunctions, and even exacerbating battery loosening during door opening and closing vibrations. This is particularly true for smart locks using lithium batteries, which generate heat. While smart locks design gaps between the battery and the compartment's inner wall to allow for heat dissipation, these gaps can cause the battery to vibrate within the compartment, leading to short circuits, abnormal power consumption, or even permanent damage to the lock. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a smart lock battery slot gap compensation structure to solve the problems mentioned in the background art, such as the gap between the battery slot and the battery, which leads to poor battery stability and poor heat dissipation.

[0016] As shown in the figure, to achieve the above-mentioned objective, this utility model provides a battery slot 3 gap 4 compensation structure for a smart lock, including a sealing plate 1 and a slot cover 2. A battery slot 3 for accommodating a battery 6 is provided between the sealing plate 1 and the slot cover 2. A gap 4 is provided between the sealing plate 1 and the battery 6 of the smart lock. A compensation component 5 is provided in the gap 4. The compensation component 5 includes a support frame 51 respectively provided in the gap 4 between the battery 6 on both sides of the smart lock and the sealing plate 1. The side wall of the support frame 51 facing the slot cover 2 is fixedly connected to the slot cover 2, the side wall facing the battery 6 abuts against the side wall of the battery 6 facing the gap 4, and the side wall facing the sealing plate 1 abuts against the sealing plate 1. After the slot cover 2 and the battery slot 3 are closed, they can abut against the sealing plate 1. A heat dissipation part for heat dissipation of the surface of the battery 6 is provided between the support frame 51 and the battery 6.

[0017] In this implementation, after the sealing plate 1 and the slot cover 2 are assembled, a battery slot 3 is formed between them to accommodate the smart lock battery 6. A gap 4 naturally forms between the sealing plate 1 and the battery 6, which serves as the installation basis for the compensation component 5. The key components of the compensation component 5 are two support frames 51, respectively positioned within the gap 4 between the battery 6 and the sealing plate 1 on both sides. The side wall of the support frame 51 facing the slot cover 2 is fixed to the slot cover 2 with screws to ensure assembly stability. The side wall facing the battery 6 is tightly abutted against the corresponding side wall of the battery 6, physically eliminating the gap 4 between the battery 6 and the sealing plate 1 and preventing the battery 6 from shaking within the battery slot 3. The side wall facing the sealing plate 1 is directly abutted against the sealing plate 1, further limiting its own displacement. When the slot cover 2 and the battery slot 3 are closed, the edge of the slot cover 2 abuts against the surface of the sealing plate 1, forming an overall closed structure, improving the dustproof and waterproof performance of the battery slot 3. To achieve heat dissipation for the battery 6, a heat dissipation section is provided between the support frame 51 and the battery 6. This embodiment can use at least two types of support frame 51 materials: the first type is ABS plastic support frame 51, which is lightweight and has a certain strength. The heat dissipation part can be a metal heat sink attached between the support frame 51 and the battery 6. The heat from the battery 6 is transferred to the surface of the support frame 51 through metal heat conduction, and then dissipated through air convection. The second type is aluminum alloy support frame 51. Aluminum alloy itself has excellent thermal conductivity. The heat dissipation part can directly utilize the metal material of the support frame 51. Several grooves are processed on the side wall of the support frame 51 facing the battery 6 to increase the heat dissipation area and accelerate the transfer of heat from the battery 6 to the support frame 51 and the external environment. Both embodiments can effectively meet the heat dissipation requirements of the battery 6 and ensure the stable operation of the smart lock battery 6.

[0018] As an improved specific implementation, the slot cover 2 extends toward the battery slot 3 and is provided with a compensation block 21. The support frame 51 is connected to the compensation block 21 on one side wall of the slot cover 2. The compensation block 21 can limit the position of the battery 6.

[0019] In this design, a compensation block 21 is integrally formed on the inner surface of the cover 2 facing the battery compartment 3. The position of the compensation block 21 corresponds to the position of the support frame 51. The core function of the compensation block 21 is to limit the movement space between the battery 6 and the cover 2. When the battery 6 is placed in the battery compartment 3 and the cover 2 is closed, the battery 6 abuts against the cover 2, preventing the battery 6 from shifting in the vertical and horizontal directions within the battery compartment 3. At the same time, the compensation block 21 can also fill the small gaps between the cover 2 and the support frame 51, further optimizing the gap compensation effect and preventing dust or moisture from entering the battery compartment 3 from the connection between the cover 2 and the support frame 51, thus protecting the battery 6 from the influence of the external environment.

[0020] As an improved embodiment, the support frame 51 has a plurality of heat dissipation holes 511 on the side wall facing the battery 6.

[0021] In implementation, the shape of the heat dissipation holes 511 can be circular or square, and the number is determined according to the size of the support frame 51, usually arranged at intervals along the length of the side wall. The heat dissipation holes 511 penetrate the side wall of the support frame 51, with one end facing the surface of the battery 6 and the other end communicating with the external environment, forming a heat dissipation channel; when the battery 6 generates heat during operation, the heat is first transferred to the side wall of the support frame 51 facing the battery 6, some of the heat is directly exchanged with the outside air through the heat dissipation holes 511, and the other part of the heat is transferred to the area around the heat dissipation holes 511 through the heat dissipation part, and then dissipated more quickly through the heat dissipation holes 511.

[0022] As an improved specific implementation, the heat dissipation part is a graphene heat dissipation block 52, which can be embedded in the heat dissipation hole 511 and form an interference fit with the heat dissipation hole 511.

[0023] In this solution, the graphene heat sink 52 adopts a sheet-like structure, and its size matches the size of the heat dissipation hole 511. During assembly, the graphene heat sink 52 is aligned with the heat dissipation hole 511 of the support frame 51. By manually pressing or gently tapping with a small tool, the graphene heat sink 52 is embedded into the heat dissipation hole 511. Due to the interference fit design, the graphene heat sink 52 remains stable after being embedded without additional fasteners and will not fall off due to daily use or vibration of the smart lock. The graphene heat sink 52 is in contact with both the surface of the battery 6 and the inner wall of the heat dissipation hole 511. When the battery 6 heats up, the heat is quickly conducted through the graphene heat sink 52 to the heat dissipation hole 511, and then transferred to the external environment through the hollow structure of the heat dissipation hole 511. Graphene material has extremely high thermal conductivity, and its heat dissipation efficiency is far higher than that of traditional metal heat sinks. It can dissipate the heat on the surface of the battery 6 in a short time, preventing the battery 6 from overheating and affecting its performance.

[0024] As an improved specific implementation, the side wall of the support frame 51 facing the battery 6 and the side wall facing the sealing plate 1 are connected by a number of support rods 512, and the support frame 51 facing the battery 6, the side wall facing the sealing plate 1, and the support rods 512 are hollowed out.

[0025] In implementation, the hollow design reduces the overall weight of the support frame 51, lowering the assembly load of the smart lock. It also increases the contact area between the support frame 51 and the air, further improving heat dissipation efficiency in conjunction with the heat dissipation holes 511. Simultaneously, the distribution of the support rods 512 ensures that the support frame 51 has sufficient strength to withstand the pressure of the closed slot cover 2 and the weight of the battery 6, preventing structural deformation due to the hollow design and ensuring the compensation effect of the gap 4. This solution can employ four support rods 512, evenly distributed at the four corners of the first and second side walls.

[0026] As an improved specific implementation, the side wall of the compensation block 21 corresponding to the upper end of the battery 6 is arranged in an arc shape, and the corner of the upper end surface of the battery 6 and the side wall facing the compensation block 21 can abut against the side wall of the compensation block 21 which is arranged in an arc shape.

[0027] In this solution, the sidewall of the compensation block 21 corresponding to the upper end of the battery 6 is machined into an arc-shaped structure. The radius of curvature of this arc matches the radius of curvature of the upper surface of the battery 6 and the corner facing the sidewall of the compensation block 21. When the battery 6 is assembled into the battery slot 3, the right-angle corner or rounded corner formed by the upper surface and the side of the battery 6 can fit and abut against the arc-shaped sidewall of the compensation block 21. Compared with the flat sidewall, the arc-shaped structure has a larger contact area and a tighter fit, improving the stability of the battery 6 in the battery slot 3.

[0028] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
