Description

Technical Field

[0001] This utility model relates to the field of battery disassembly and assembly technology, specifically to a structure that enables quick battery disassembly and assembly. Background Technology

[0002] In the current consumer electronics industry, wearable devices are experiencing continuous market expansion due to their portability and intelligence. Major markets such as the EU and the US have introduced mandatory regulations requiring that batteries in these products be disassembled and replaced without damaging the overall device structure. This aims to improve the recycling rate of electronic waste and meet environmental and maintainability requirements. Against this backdrop, battery disassembly and assembly solutions that comply with regulations while considering user experience and cost control have become a core focus of industry research and development. However, existing technologies have several drawbacks: screw-fixed systems require specialized micro screwdrivers, increasing the user's operational threshold; repeated disassembly and assembly can lead to thread wear and damage to waterproof gaskets, resulting in battery loosening and poor conductivity; traditional snap-fit ​​systems rely on the elastic deformation of the snaps to disengage, which can easily cause irreversible stress damage, leading to decreased locking reliability after long-term use, and often requiring tools for assembly, resulting in low efficiency; drawer-type structures are complex and space-consuming, conflicting with the miniaturization requirements of wearable devices, and the guide rail clearance also affects waterproof performance. Furthermore, the large number of parts and high processing precision requirements increase costs. Furthermore, existing solutions generally fail to effectively address the issue of poor contact between the battery and the motherboard contacts caused by accumulated tolerances. Some foam compensation solutions experience elasticity degradation after repeated disassembly and reassembly, and most solutions are designed for specific products with poor technology reusability. Companies need to conduct repeated research and development to adapt to different models, further increasing the R&D cycle and costs. In summary, current solutions are unable to meet the comprehensive requirements of compliance, reliability, low cost, and convenience, and there is an urgent need for a new battery quick disassembly and reassembly structure to overcome industry pain points. Utility Model Content

[0003] The present invention aims to overcome at least one of the defects of the prior art and provide a structure that enables quick battery installation and removal, so as to realize the quick installation and removal of batteries in wearable devices.

[0004] This utility model provides a structure for quick battery installation and removal, including a main body, an upper shell, and a locking mechanism. The battery is disposed within a cavity formed by the main body and the upper shell. A locking position is provided on one side of the main body. The locking mechanism includes a button and a spring. The button is embedded in the locking position, one end of the spring is sleeved on the button, and the other end abuts against the main body. The upper shell has a first latch and a second latch, the main body has a third latch, and the end of the button has a fourth latch. The first latch and the fourth latch are detachably fastened together. The second latch and the third latch are detachably fastened together. By pushing the button, the spring is compressed and the first latch disengages from the fourth latch, thus loosening the upper shell from the main body and removing the battery.

[0005] The structure of this utility model mainly comprises three core components: a main body, an upper shell, and a locking mechanism. The battery is confined within the cavity formed by the main body and the upper shell, ensuring a fixed battery installation position. A locking position is provided on one side of the main body, providing an installation reference for the locking mechanism. The locking mechanism consists of a button and a spring. The button is embedded in the locking position for positioning, and one end of the spring is fitted onto the button, while the other end abuts against the main body, forming a resettable elastic structure. The upper shell has a first and a second latch, the main body has a corresponding third latch, and the button has a fourth latch at its end. A double locking relationship is formed by the engagement of the first and fourth latches and the engagement of the second and third latches. During disassembly, simply push the button to compress the spring and disengage the fourth latch from the first latch, loosening the upper shell from the main body, allowing the battery to be removed.

[0006] Therefore, this utility model, through a simple combination of the main body, upper shell, and locking components, coupled with a double-buckle locking structure, not only ensures the structural stability after battery installation, but also achieves quick disassembly and assembly without tools by utilizing the elastic reset function of the spring and the push-type operation of the button, meeting the regulatory requirements for removable batteries in the EU and other regions. At the same time, the double-buckle design greatly improves the reliability of the structural locking, preventing the battery from loosening during device use.

[0007] Furthermore, the button part includes a button cap and a button block; the button block includes a base part and a fastening part that are vertically connected; one end of the base part is detachably inserted into the button cap; the middle part of the other end is inserted into a spring; the fourth buckle is provided at the end of the fastening part.

[0008] By breaking down the button section into a modular structure of button caps and button blocks, it is easier to process each component individually. For example, button caps can be made of different materials to improve the feel, while button blocks can be made of high-strength materials to ensure the strength of the latches, reducing production difficulty. The insertion and engagement of the base with the spring can precisely limit the installation position of the spring, preventing the spring from shifting or tilting during pressing or resetting, and ensuring the stability of the button's operation. The independent setting of the latching part makes the layout of the fourth latch fit the position of the first latch on the upper shell more closely, optimizing the latching force and improving the durability of the latching engagement.

[0009] Furthermore, the base portion and the fastening portion are integrally formed, forming an L-shape; one end of the base portion is also provided with a fifth buckle and a sixth buckle; the inner wall of the button cap is provided with a locking groove that engages and locks with the fifth buckle and the sixth buckle.

[0010] The integrated design of the base and the fastening part eliminates the assembly gap between the two, greatly improving the overall structural strength of the button block and preventing the buckle from failing due to loosening of parts during long-term use. The L-shaped structure can cleverly adapt to the internal space layout of the main body, rationally planning the installation path of the button part within the limited internal space of the wearable device and reducing space occupation. The cooperation of the fifth and sixth buckles with the button cap locking groove forms a double fixation of plug-in and buckle, which is more secure than simple plug-in and prevents the button cap from falling off during frequent pressing, improving the reliability of user operation and the service life of the device.

[0011] Furthermore, the locking position is provided with a seventh buckle and an eighth buckle; the other end of the base portion is embedded in the seventh buckle and the eighth buckle.

[0012] The seventh and eighth latches provide lateral restraint to the base, effectively limiting the lateral offset or wobbling of the button during pressing and ensuring that the button always moves in the preset direction. This ensures the precise disengagement and engagement of the fourth latch and the first latch, preventing disassembly and assembly from being stuck or the latches from being damaged due to button offset. At the same time, the latch-type restraint does not require additional fixing structures, simplifying the assembly process and improving production efficiency.

[0013] Furthermore, the end of the locking position is shaped like a mountain; the two ends are the seventh and eighth latches; and the middle part abuts against the spring.

[0014] The mountain-shaped locking position of this utility model achieves multiple uses with one structure. The buckles at both ends can directly limit the base part, while the middle area provides a stable abutment support point for the spring. There is no need to design a separate positioning boss or groove for the spring, which simplifies the processing technology of the locking position of the main body and reduces manufacturing costs. At the same time, the precise abutment between the spring and the middle of the mountain shape can ensure that the spring is subjected to uniform force, avoid unilateral wear caused by force deviation, extend the service life of the spring, and ensure the long-term stable reset performance of the button part.

[0015] Furthermore, the inner side of the upper shell is provided with a mounting groove, and one or more fixing ribs are provided on the side of the mounting groove; the side of the upper shell is also provided with a disassembly groove.

[0016] The mounting slot provides precise installation space for subsequent components (such as foam), preventing foam displacement; the side fixing ribs can laterally limit the battery in the cavity, preventing the battery from moving around in the cavity when the device shakes or falls, protecting the connection between the battery electrodes and the motherboard contacts; the disassembly slot on the side of the upper shell provides a convenient point of force for disassembly and assembly. Users can use simple tools such as disassembly pry tools to insert into the disassembly slot to pry the upper shell, or they can directly pry it open with their fingers. At the same time, the operation of the button section can quickly separate the upper shell from the main body, further reducing the difficulty of disassembly and assembly and improving the user experience.

[0017] Furthermore, foam is also provided inside the mounting slot. The foam is elastic and can flexibly compress the battery in the Z direction, which can offset the gaps caused by the cumulative machining tolerances of the main body, the upper shell, and the battery, ensuring that the battery and the motherboard contact spring always maintain stable contact, avoiding problems such as poor conductivity, equipment failure, or sudden drop in battery life caused by gaps; at the same time, the flexibility of the foam can absorb the impact force when the equipment vibrates or is dropped, providing cushioning protection for the battery, reducing the risk of battery casing damage, and improving the equipment's drop resistance and battery life.

[0018] Furthermore, the main body includes a middle shell, a lower shell, and a main board; the battery is disposed in the accommodating cavity formed by the middle shell and the upper shell; the main board is fixed in the lower shell; the middle shell and the lower shell are fixedly connected.

[0019] The modular design of the main components allows for a clear division of labor among the functional parts. The middle shell focuses on accommodating the battery in conjunction with the upper shell, while the lower shell focuses on supporting the motherboard. This facilitates the independent assembly, debugging, and maintenance of each component. Only the lower shell needs to be disassembled, without touching the battery housing, thus reducing the impact of maintenance on the battery. At the same time, the modular design reduces the processing complexity of individual components, making mass production easier. Furthermore, if a component is damaged, only the corresponding component needs to be replaced, reducing maintenance costs.

[0020] Furthermore, the lower shell is provided with a support rib; the main board is provided with a spring for communicating with the battery; the support rib passes through the main board to prevent the spring from being over-pressured.

[0021] The support rib is integrally formed with the lower shell. After passing through the motherboard, the support rib can limit the maximum downward stroke of the battery when it is assembled and fastened. This prevents the battery from applying excessive pressure to the spring contact due to overly tight assembly or pressure on the equipment, which could lead to permanent deformation and loss of conductivity of the spring contact. This effectively protects the spring contact and extends its service life. At the same time, the support rib can also play an auxiliary role in fixing the motherboard, preventing the motherboard from shifting due to vibration during equipment use. This ensures the relative position stability between the motherboard and the battery spring contact, further guaranteeing the reliability of conductivity.

[0022] Furthermore, a soft rubber ring is provided at the connection between the button cap and the button block; a waterproof gasket is provided between the upper shell and the middle shell. The soft rubber ring fills the gap between the button cap and the button block, and the waterproof gasket fills the gap between the upper shell and the middle shell, forming a sealing barrier to effectively prevent dust and moisture from entering the device from the button connection, improving the device's waterproof and dustproof performance and adapting to complex usage environments such as humid and dusty conditions. At the same time, the soft rubber ring and the waterproof gasket have a cushioning effect, reducing collisions and friction during disassembly and assembly, reducing operational noise, improving the user's pressing feel, and optimizing the user experience.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This utility model achieves multi-dimensional technical advantages through a hierarchical and modular structural design: First, in terms of ease of disassembly and assembly, the combination of buttons, springs, and multiple sets of clips allows for quick battery disassembly and assembly without special tools, meeting the battery removability regulations of major global markets; Second, in terms of structural reliability, the design of double-clip locking, precise spring positioning, support ribs to prevent overvoltage, and foam to compensate for tolerances ensures stable battery installation and reliable conductivity, preventing structural loosening or functional failure during long-term use; Third, in terms of production and maintenance, modular disassembly (divided into button caps and button blocks, and the main body into middle and lower shells) simplifies the processing and assembly process, reducing production and maintenance costs; Fourth, in terms of user experience, soft rubber rings and waterproof gaskets improve sealing and feel, disassembly slots reduce disassembly and assembly difficulty, and foam cushioning protects the battery, balancing practicality and comfort; Fifth, in terms of spatial adaptability, the L-shaped button block and mountain-shaped locking position design make full use of the internal space of the device, adapting to the miniaturization requirements of wearable devices. Overall, this utility model effectively solves the pain points of "complex disassembly and assembly, low reliability and high cost" in traditional battery disassembly and assembly structures, and combines compliance, practicality and economy.
