Description

TECHNICAL FIELD

[0001] The utility model relates to wearable equipment technical field, concretely relates to a detachable battery structure. BACKGROUND

[0002] The EU has mandated the use of removable batteries in smartphones and cameras since 2027, which requires users to replace the battery of their smartphone or wearable device without the need for special tools. This regulation aims to promote environmental protection and provide consumers with more choices. Although this regulation will not take effect for a few years, it provides manufacturers with sufficient time to adapt to the change. In addition, the new EU battery regulation (EU) 2023 / 1542 also makes detailed provisions for other aspects of batteries, including hazardous substance restrictions, carbon footprint requirements, recycling, etc. However, the specific requirements for removable batteries are mainly aimed at smartphones and cameras.

[0003] Existing technologies such as earphones, smartwatches, and other wearable devices use non-removable battery structures, which require users to use special tools to disassemble them. However, due to the high precision requirements, users may inadvertently cause the wearable device to malfunction during self-disassembly, so there is an urgent need to develop a structure that does not affect the use effect and allows users to quickly disassemble and assemble the battery. SUMMARY

[0004] The utility model aims to overcome at least one of the above-mentioned prior art defects, and provides a detachable battery structure to achieve the purpose of easy disassembly, low cost, and high reliability.

[0005] Specifically, the utility model provides a detachable battery structure, which is arranged in the shell of a wearable device, and the side wall of the shell is provided with a clamping groove; the detachable battery structure comprises a rotating cover and a disassembly piece; a battery module is arranged between the shell and the rotating cover; the bottom side of the rotating cover is provided with a buckle; the top is provided with a disassembly slot for inserting and pulling out the disassembly piece; the rotating cover is rotated by the disassembly piece to realize the locking and unlocking between the buckle and the clamping groove.

[0006] The shell can refer to the shell of a wearable device, or another designed shell can be installed in the wearable device to achieve battery installation. The utility model adopts a disassembly piece for rotating disassembly, which is simple to operate. Preferably, the disassembly slot in the utility model is a linear slot with a width greater than the thickness of the disassembly piece; the disassembly piece can be easily inserted into the disassembly slot; and the two are non-fixedly connected. In addition to the structure of the linear slot, other structures such as plum blossom points, triangles, and polygons can be selected, as long as the corresponding disassembly piece can be inserted and pulled out, and the rotating cover can be rotated by rotating the disassembly piece after insertion. All of the above are within the scope of protection of the utility model.

[0007] The battery module includes a control motherboard, battery blocks, and other structural components. The control motherboard is located at the bottom of the battery blocks and has spring contacts that connect to the battery blocks for electrical connection. The housing has an opening at the top and slots on its side walls. A rotating cover is placed directly over the opening at the top. By gently pressing down, the battery blocks are pressed against the spring contacts, and rotating the cover causes its latches to engage with the slots, securing the cover. Similarly, rotating the cover in the opposite direction disengages the latches from the slots, unlocking the cover from the housing. The battery blocks can then be removed by opening the cover and replacing them.

[0008] Furthermore, a stop is provided at the entrance of the card slot to prevent the buckle from springing back and unlocking.

[0009] To prevent the rotating cover from shifting during use and causing the buckle to detach from the slot, this invention also includes a stop at the entrance of the slot. The stop is integrally formed with the slot and is preferably located at the top of the slot entrance as a downward-pointing dot-shaped protrusion. When the buckle of the rotating cover is rotated into the slot opening, the stop increases the damping feel and helps the user confirm whether the buckle is embedded in the slot. When the rotating cover is rotated in the reverse direction, since both the rotating cover and the housing are made of plastic, there is some room for deformation, and the smooth transition of the stop allows the buckle to unlock from the slot. The stop can then be reset after slight deformation.

[0010] Furthermore, the top side of the rotating cover is provided with a pry opening.

[0011] After the latch of the rotating cover is unlocked by rotating it out of the slot, a pry opening is designed on the side of the rotating cover to facilitate its removal. The rotating cover can be pried open and removed by inserting a pry tool into the pry opening and moving upwards, or by using your hand to hold the pry opening upwards and remove the rotating cover. More preferably, the two ends and the middle of the housing have a height difference; that is, when the rotating cover is rotated 90 degrees, the pry opening rotates to the lower position in the middle of the housing and is exposed; when rotated in the opposite direction, the pry opening rotates to the higher position at both ends of the housing and is hidden.

[0012] Furthermore, the bottom surface of the rotating cover is also provided with battery foam, which is sandwiched between the rotating cover and the battery module. The battery foam is adhered to the inner wall of the rotating cover 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, which facilitates battery removal and replacement, and the foam can be reused. The thickness of the battery foam can be designed and adjusted according to the actual battery and casing thickness. The design of the battery foam prevents poor contact of the spring contacts due to tolerance accumulation when the rotating cover presses the battery block in the Z-axis direction. At the same time, it also provides buffer space on the longitudinal axis for the buckle to enter the slot after passing through the stop, making the locking and unlocking process smoother.

[0013] Furthermore, the inner side of the rotating cover is provided with one or more battery fixing ribs.

[0014] The battery fixing ribs are the protrusions on the side wall of the rotating cover. Preferably, this invention designs three battery fixing ribs. Since the battery block will flip when the rotating cover is opened, in order to prevent the battery from falling and being damaged during the flipping process, this invention designs three battery fixing ribs, which can effectively prevent the battery block from slipping, without affecting battery disassembly, and improve the stability of battery block installation during use.

[0015] Furthermore, a waterproof rubber ring is provided between the rotating cover and the housing. The waterproof rubber ring is used to seal the housing and the rotating cover, serving the purpose of waterproofing and dustproofing, while also making the fit between the two more tight.

[0016] Furthermore, the housing includes an upper shell and a lower shell, which are fixedly connected, and an internal battery compartment for installing the battery module is formed; the slot is provided on the side wall of the upper shell; the top of the upper shell has an opening, and the rotating cover is inserted into the opening and rotatably connected to the upper shell by the buckle.

[0017] In this invention, the upper and lower shells can be detachably connected by adhesive application, tenon and mortise joints, or threaded fasteners. The control motherboard is installed in the lower shell and can be secured by adhesive application.

[0018] Furthermore, the opening of the upper shell is roughly circular, with a recessed area in the center.

[0019] The above design results in a top cover that is high at both ends and concave in the middle, creating a height difference in the thickness of the sides when the rotating cover is inserted into the opening of the top cover. Combined with the design of the pry hole on the rotating cover, in the locked state, the pry hole can be rotated to either side of the top cover to be hidden. When rotated 90° to unlock, the pry hole is located in the concave area in the middle of the top cover, making it exposed and easy to remove the rotating cover after unlocking.

[0020] Furthermore, one or more supporting ribs are provided on the bottom inner wall of the lower shell.

[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 foam on top can ensure the contact between the battery and the spring by selecting an appropriate thickness.

[0022] Furthermore, there are three card slots; the number of buckles matches the number of card slots; and the line connecting the points where the three card slots are located forms a non-equilateral triangle.

[0023] This invention achieves a foolproof effect by setting the slots and buckles at different angles. Therefore, the three slots are designed in asymmetrical positions, requiring the rotating cover to be rotated to a fixed angle to achieve matching between the buckle and the slot, which can prevent the battery module from being assembled backwards.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. This invention proposes a novel quick-disassembly battery design using the simplest snap-fit ​​and disassembly tabs. The battery block is secured by battery fixing ribs, facilitating easy disassembly and assembly. The battery foam ensures proper conductivity between the battery block and the spring contacts, preventing poor conductivity. Furthermore, a waterproof rubber ring is incorporated, providing waterproof and dustproof protection and enhanced installation stability. This detachable battery structure allows for quick and easy disassembly and assembly using simple tools.

[0026] 2. In terms of cost: This utility model has a simple structure, fewer structural parts, high yield in mass production, and low cost.

[0027] 3. Design Aspects: The design of the battery fixing ribs has been verified to be effective through hand-made prototypes, enabling rapid assembly, fixing, and disassembly of the battery block without increasing additional costs; the design of the battery overvoltage protection ribs can prevent the battery from over-pressureing the spring contacts, achieving overvoltage protection for the battery block 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, leading to poor conductivity; the battery module is assembled by snap-fit ​​rotation and has an anti-reverse stop, and the foolproof design of this utility model prevents the battery from being installed backwards.

[0028] 4. In terms of reliability: The structural strength of this design can be enhanced by adjusting the interference amount, and the disassembly process requires pressing the rotating cover and the disassembly piece simultaneously, which can meet the international requirements for removable batteries.

[0040] Example 1

[0041] This embodiment provides a removable battery structure, such as Figure 1 As shown, it is located inside the housing 1 of the wearable device, combined with Figure 2 As shown, the housing 1 includes an upper shell 11 and a lower shell 12, which are fixedly connected by adhesive dispensing, forming an internal battery compartment for installing the battery module; combined with Figures 3-4 As shown, the detachable battery structure includes, from top to bottom, a disassembly piece 2, a rotating cover 3, and battery foam 4. The side wall of the upper shell 11 has three slots 5, and the bottom side of the rotating cover 3 has three latches 6 that match the slots 5. The top of the rotating cover 3 has a disassembly groove 7 for inserting and removing the disassembly piece 2. The top of the upper shell 11 has an opening, and the rotating cover 3 is inserted into the opening and rotatably connected to the upper shell 11 via the latches 6. The rotating cover 3 is rotated using the disassembly piece 2 to lock and unlock the latches 6 and the slots 5. The battery foam 4 is sandwiched between the rotating cover 3 and the battery module.

[0042] like Figure 2 As shown, the disassembly groove 7 in this utility model is a linear groove, the width of which is greater than the thickness of the disassembly piece 2; this allows the disassembly piece 2 to be easily inserted into the disassembly groove 7; and the two are not fixedly connected. Combined with... Figure 3 As shown, the inner side of the rotating cover 3 is also provided with three raised battery fixing ribs 50, which can effectively prevent the battery module from slipping off, without affecting battery disassembly, and improve the stability of battery block 9 installation during use. A waterproof rubber ring 60 is also provided between the rotating cover 3 and the housing 1. The waterproof rubber ring 60 is used to seal the housing 1 and the rotating cover 3, serving the purpose of waterproofing and dustproofing, while also making the fit between the two more tight.

[0043] like Figure 2 As shown, the battery module includes structural components such as a control motherboard 8 and a battery block 9; the control motherboard 8 is installed in the lower shell 12 and can be fixed by adhesive dispensing, while the battery block 9 is located above the control motherboard 8. (Combined)Figure 5 As shown, the control motherboard 8 is equipped with a spring contact 10, which contacts the battery block 9 to achieve power connection. The bottom inner wall of the lower shell 12 is provided with three support ribs 13, which penetrate the control motherboard 8 and extend to the bottom of the battery block 9. These support ribs 13 prevent overvoltage of the battery. When the battery block 9 is assembled and fastened, these three support ribs 13 support the battery. The foam above, by selecting an appropriate thickness, ensures contact between the battery and the spring contact 10.

[0044] like Figures 6-7 As shown, a stop 20 is also provided at the entrance of the slot 5. The stop 20 is used to prevent the buckle 6 from springing back and unlocking. The stop 20 is integrally formed with the entire slot 5 and is a downward-pointing dot-shaped protrusion. When the buckle 6 of the rotating cover 3 is rotated into the opening of the slot 5, the design of the stop 20 increases the damping. Since both the rotating cover 3 and the housing 1 are plastic parts, they have a certain amount of deformation space. When the rotating cover 3 is rotated in the opposite direction, the buckle 6 can unlock from the slot 5 due to the smooth transition of the stop 20. The stop 20 can also be reset after slight deformation.

[0045] like Figure 8 As shown, the top side of the rotating cover 3 is provided with a pry opening 30. Combined with... Figure 1 and Figure 2 As shown, the opening of the upper shell 11 is roughly circular, with a recessed area 40 in the center. In the locked state, the pry bar 30 can be rotated to either side of the upper cover to hide it. When rotated 90° to unlock, the pry bar 30 is located in the recessed area 40 in the center of the upper cover, making it exposed.
