Description

Technical Field

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

[0002] With the advancement of technology, wearable devices such as smartwatches and smart rings are becoming increasingly powerful, placing higher demands on batteries. Non-removable battery designs allow for more compact devices, optimizing performance. This design also better manages battery-device compatibility, ensuring full battery performance, reducing energy loss, and improving energy efficiency. Secondly, non-removable battery designs prioritize user safety. The integrated battery design reduces safety hazards such as poor battery contact and short circuits. Furthermore, this design prevents battery damage caused by improper user operation, such as overcharging, thus reducing the risk of device malfunction. Thirdly, from a production management perspective, non-removable battery designs simplify production processes and improve efficiency. This also avoids the potential damage or safety risks associated with users replacing batteries themselves. However, this design also presents some challenges. For example, if the battery is depleted or damaged, the entire device may need to be replaced, increasing user costs. Additionally, improper disposal of non-removable lithium-ion batteries can potentially harm the environment.

[0003] International requirements for wearable device batteries are gradually shifting towards removable and replaceable designs, particularly with the EU's explicit regulations. This means that wearable devices sold in the EU market must have batteries designed to be removable and replaceable. Therefore, developing a structure for quick battery removal is urgently needed to align with international standards. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a structure that enables quick battery disassembly, so as to achieve the purpose of low cost, convenient and fast disassembly.

[0005] Specifically, this utility model provides a structure that enables quick battery disassembly, including a first housing, a second housing, and a disassembly component. The battery module is disposed in a battery compartment formed by the first and second housings. A first buckle is provided on one side of the first housing, and a second buckle is provided on the other side. A first slot and an unlocking hole are provided on one side of the second housing, and a second slot is provided at the other end. The first and second buckles engage with the first and second slots respectively from the inside of the second housing. By inserting the disassembly component into the unlocking hole and pressing the first buckle, the first buckle deforms and disengages. The first and second housings of this utility model can be quickly disassembled and installed using the buckles at both ends. Locking and unlocking are achieved using the elastic deformation and reset of the first buckle. The first and second buckles are integrally formed with the first housing and are plastic parts with a certain amount of elastic deformation. During installation, the second buckle is first engaged with the second slot, and then the side of the first housing where the first buckle is located is pressed downwards to engage the first buckle with the first slot. When disassembly is required, insert the disassembly tool into the unlocking hole, push the first buckle inward to disengage it from the first slot, and lift the first housing upward on the unlocked side to disengage the second buckle from the second slot, thus unlocking the device.

[0006] Furthermore, the structure of this utility model that enables quick battery disassembly also includes a silicone ring, which is disposed between the first housing and the second housing; the silicone ring is fixed to the second housing as a whole, or the silicone ring is fixed to the lower side of the first housing.

[0007] Since both the first and second housings are made of plastic, their connection is not well sealed. Therefore, this invention also includes a silicone ring for sealing the first and second housings. By adjusting the interference fit of the silicone ring, waterproofing and dustproofing can be easily achieved, while also making the fit between the two housings tighter.

[0008] Preferably, a baffle is provided on one side of the silicone ring, the baffle is integrally formed with the silicone ring, the baffle is embedded between the unlocking hole and the first buckle, and the baffle is provided with a groove to facilitate the positioning of the disassembly part.

[0009] Since the unlocking hole connects to the outside and the battery compartment, there is a risk of water entering the battery compartment. This utility model has a baffle extending from the side of the silicone ring. The silicone ring is pre-pressed by the first buckle or the first slot to prevent water from entering. The baffle is designed with a positioning groove that matches the disassembly part, which facilitates the insertion and positioning of the disassembly part to push the first buckle and achieve quick unlocking.

[0010] More preferably, the compression deformation of the silicone ring is 0.1 to 0.3. The upper and middle shells use waterproof silicone rings, and more preferably, the compression deformation of the silicone ring is 0.15, which can ensure that the sealing effect is not lost after multiple disassemblies and prevent water from entering the battery compartment.

[0011] Preferably, the disassembly component is a PIN pin or a SIM card ejector pin, which is disassembled by pushing the first latch. Further, the second housing has one or more receiving holes, and each receiving hole has a spring; when the first and second housings are locked, the spring is in a compressed state.

[0012] In order to facilitate the automatic pop-out of the first housing after the first buckle is disengaged, this utility model installs a spring on the second housing. When a PIN pin or SIM card pin is inserted to push the first buckle, the first buckle is deformed and disengaged, and the spring pops the first buckle and the battery block up together.

[0013] Preferably, a fixing post is provided in the receiving hole, and one end of the spring is sleeved on the fixing post.

[0014] More preferably, the springs are in two sets, symmetrical about the insertion direction of the unlocking hole. This ensures that when the first housing pops out, the force is evenly distributed on both sides, preventing the battery block from tipping over when the first housing pops up.

[0015] Furthermore, the inner side of the first housing is provided with a battery fixing compartment. The battery module includes a battery block, a spring contact, and a control motherboard. The top surface of the battery block is fixed in the battery fixing compartment with adhesive, and the bottom surface is connected to the control motherboard through the spring contact. The spring contact is mounted on the control motherboard. The bottom of the battery block is provided with a positive terminal area and a negative terminal area, wherein the positive terminal area is connected to the positive pin of the control motherboard, and the negative terminal area is connected to the negative pin of the control motherboard.

[0016] Preferably, the first and second clips are L-shaped clips. L-shaped clips are easier to install and remove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] Assembly: This utility model is assembled by snaps at both ends, which allows for multiple disassembly and assembly without damaging the original structure; the assembly process is simple, and users can easily learn to complete the disassembly and assembly.

[0019] In terms of cost: the structure is simple, with few structural parts, making mass production feasible, and the replacement cost is low, requiring only better battery adhesive.

[0020] Design-wise: This design has been verified to be effective through prototype testing. The disassembly and assembly process is smooth. If it is subsequently manufactured using molded parts, mass production can be easily achieved.

[0021] In terms of reliability: Waterproofing is achieved through a pre-pressed silicone ring with a snap-fit ​​mechanism. By adjusting the interference fit of the silicone ring, waterproofing and dustproofing can be easily achieved. Furthermore, by adjusting the snap-fit ​​engagement, it can easily pass reliability tests such as drop and vibration tests. It can simultaneously meet the removable battery regulations expected in the EU and the US. Attached Figure Description
