Description

Technical Field

[0001] This utility model relates to the field of wearable device technology, specifically to a battery quick-release and disassembly structure. Background Technology

[0002] Starting February 18, 2027, portable batteries must be designed to be easily removable and replaceable by the end user at any point during the product's lifespan. Users should be able to easily remove the battery using readily available tools, without the need for specialized tools, unless such tools are provided free of charge. Therefore, structural engineers are seeking solutions that meet reliability requirements, facilitate easy replacement, and do not negatively impact the user experience.

[0003] In existing technologies, wearable devices such as headphones and smartwatches use non-removable battery structures, which require users to use special tools to remove. However, due to the high precision requirements, users may cause malfunctions in the wearable device due to operational errors when disassembling and assembling the battery themselves. Therefore, there is an urgent need to develop a structure that does not affect the performance of the device and allows users to quickly and easily disassemble and assemble the battery. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a battery quick-disassembly and assembly structure to achieve low cost, simple structure and quick battery disassembly and assembly.

[0005] This utility model provides a quick battery disassembly and assembly structure, including a first housing and a second housing, the first housing, a disassembly assembly, and the second housing. The first housing and the second housing are detachably connected, forming a battery compartment inside, and a battery module is installed in the battery compartment. The disassembly assembly is located on the side of the connection between the first housing and the second housing, and the first housing and the second housing can be unlocked and locked by plugging and unplugging the disassembly assembly.

[0006] The first and second housings of this utility model can be the housings of a wearable device, or a separately designed housing installed inside the wearable device, enabling the installation of the battery module. The first and second housings of this utility model are detachably connected, and the disassembly assembly is used to lock the first and second housings, allowing for quick assembly and disassembly of the battery module without the need for other tools, thus offering high practicality. The disassembly assembly can be an insert-type locking structure or a plug-in structure for quick fixing of the first and second housings, both of which are within the protection scope of this utility model. The battery module includes structural components such as a control motherboard and a battery block; the control motherboard is located at the bottom of the battery block and has spring contacts, which contact the battery block to achieve electrical connection.

[0007] The second housing can be a single unit or assembled from two housings, both of which are within the protection scope of this utility model.

[0008] Furthermore, the first housing has a first buckle on one side and a second buckle on the other side; the second housing has an insertion hole on one side and a slot on the other side; one side of the first housing and the second housing is fixed by inserting the disassembly assembly into the first buckle and the insertion hole; the other side of the first housing and the second housing is fixed by engaging the second buckle and the slot.

[0009] The first and second housings of this utility model are two-point fixing structures, that is, the two ends are fixed by the first and second buckles of the first housing respectively; wherein the second buckle is L-shaped, and the slot of the second housing is an inward extension block of the side wall; by hooking the bottom of the second buckle onto the extension block, one end is quickly locked. When the first and second housings are fastened together, the second buckle locks with the slot, and at this time the first buckle is located inside the socket; the insertion end of the disassembly component matches the shape of the socket, and one end of the disassembly component passes through the socket and is inserted into the first buckle to lock the socket and the first buckle; when disassembly is required, the disassembly component is pulled outward, at which time the first buckle is unlocked from the socket, and the first housing is lifted upward from the unlocked end of the first housing. At this time, the second buckle can be disengaged from the slot due to the change of angle, thus realizing the separation of the first and second housings and realizing the replacement of the battery module.

[0010] Preferably, the first buckle is sheet-shaped with a locking hole in the middle; the disassembly component is inserted into the locking hole from the insertion hole to achieve fixation. The first buckle of this utility model has a simple structure and low manufacturing cost. The sheet-shaped structure makes its closing and opening smoother.

[0011] Furthermore, the disassembly assembly includes a button section and a locking section; the button section and the locking section are fixedly connected, and by pressing the button section, the locking section is inserted into the socket and the first buckle in sequence to lock the first housing and the second housing.

[0012] The button is designed for pressing and pushing the locking part or for easy removal of the locking part. More preferably, the button and locking part can be a one-piece molded structure, making the entire disassembly assembly T-shaped; the button and locking part can be made of flexible materials, such as silicone or soft rubber; and the locking part has an interference fit relative to the socket, so that after the locking part is inserted into the socket, there is no redundant space, preventing the connection between the first and second shells from becoming loose. Similarly, the button is also made of flexible material, so that when unlocking, it is easy to pry one side of the button and then pull it out as a whole. Preferably, the disassembly assembly also includes a rubber ring, and the locking part has multiple sets of annular grooves into which the rubber ring is embedded. The rubber ring of this utility model can be assembled later or double-shot molded, both of which are within the protection scope of this utility model.

[0013] More preferably, there are two sets of rubber rings, which are embedded in the annular groove to fix the rubber rings to the locking part. At the same time, the rubber rings protrude slightly relative to the locking part, so that the locking part is in an interference fit when inserted into the socket, which can prevent the button from automatically disengaging and improve the stability of installation.

[0014] Preferably, the opening of the socket is also provided with a groove to facilitate the removal of the button.

[0015] Preferably, the side of the first housing is also provided with a disassembly groove.

[0016] To facilitate the removal of the first housing, this utility model also designs a disassembly groove on the side of the first housing. The first housing can be pried open using a disassembly tool, or the first housing can be peeled off upwards by holding the disassembly groove with your hand.

[0017] Preferably, battery foam is provided between the first housing and the battery module; multiple battery fixing ribs are provided on the inner side wall of the first housing.

[0018] The battery foam is sandwiched between the first housing and the battery module. The battery foam is adhered to the inner wall of the first housing facing the battery compartment; the battery block is inserted into the battery compartment. The battery foam on the battery side has no double-sided adhesive, facilitating battery removal and replacement, and the foam is reusable. The thickness of the battery foam can be designed and adjusted according to the actual battery and housing thickness, etc. The design of the battery foam prevents poor contact of the spring contacts due to tolerance accumulation when the first housing presses the battery block in the Z-axis direction. The battery fixing ribs are protrusions on the side wall of the first housing. Preferably, this invention designs three battery fixing ribs. Since the battery block will flip when the first housing is opened, the three battery fixing ribs of this invention can effectively prevent the battery block from slipping and causing damage during the opening and flipping process, without affecting battery removal, and improving the stability of battery block installation during use.

[0019] Furthermore, a waterproof gasket is provided between the first housing and the second housing. The waterproof gasket is used to seal the first housing and the second housing, serving the purpose of waterproofing and dustproofing, while also making the two fit together more tightly.

[0020] Furthermore, the bottom inner wall of the second housing is provided with one or more sets of support ribs, which are used to prevent the battery module from being over-voltaged.

[0021] Another inventive point of this utility model is the design of the support ribs. In some preferred embodiments of this utility model, the support ribs are designed to be three in number. The support ribs penetrate the control motherboard and extend to the bottom of the battery block. The support ribs can prevent the battery from being over-voltaged. When the battery block is assembled and fastened, the battery is supported by these three support ribs. The battery foam above can ensure the contact between the battery block and the spring piece by selecting an appropriate thickness.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] Assembly: This invention features a modular design that allows for quick assembly and disassembly of the first and second housings. The button assembly utilizes soft rubber interference fit, which can be completed by hand, offering convenience and speed. The battery block is secured with battery fixing ribs, providing greater stability and easy disassembly and assembly. The battery foam ensures proper conductivity of the battery block, preventing poor continuity. The battery module is assembled using snap-fit ​​mechanisms, also allowing for quick and easy hand assembly.

[0024] In terms of cost: The battery quick-disassembly and assembly structure of this utility model has a simple overall structure, fewer structural parts, high yield in mass production, and low cost.

[0025] In terms of design: The design of the battery fixing rib in this utility model has been verified to be effective through hand-made prototypes, enabling rapid assembly, fixing, and disassembly of the battery without increasing additional costs; the design of the battery overvoltage protection rib can prevent the battery from over-pressuring the spring contacts, achieving battery overvoltage protection without increasing additional costs; the design of the battery foam can prevent the gap between the battery and the spring contacts from exceeding the tolerance, which would lead to poor conductivity; the locking part uses soft rubber interference fit to provide damping to prevent dislodgement, all of which can be achieved without increasing additional costs.
