Description

Technical Field

[0001] The utility model relates to the technical field of electronic devices, and particularly relates to a battery locking device and an electronic device. Background Art

[0002] In a wide range of fields such as communication products, industrial equipment, and consumer products, the demand for detachable and replaceable batteries has always occupied an important position. This demand stems from multiple aspects, including the convenience of device maintenance, the flexible improvement of battery life, and the ability to meet the changing power requirements in different usage scenarios. However, with the continuous innovation and complexity of product forms and stacking structures, higher requirements are imposed on the locking structure design of detachable batteries.

[0003] Traditional battery locking structures perform well when dealing with simple battery forms, but their adaptability is significantly insufficient when facing special-shaped batteries such as L-shaped batteries. Due to the unique shape design of L-shaped batteries, not only does it increase the assembly difficulty, but it also poses more stringent challenges to the stability and reliability of the locking structure.

[0004] Currently, although there are various locking structure designs for L-shaped batteries on the market, they all have different degrees of defects. For example, the inertia-enhanced locking system proposed in the existing patent CN102333928A, although it enhances the locking stability to a certain extent, its assembly process is complex, and the self-locking method relying on the elastic force of the elastic sheet results in poor reliability of the locking itself, and it is prone to loosening or failure problems during long-term use.

[0005] Another common locking structure is to fix the L-shaped long battery through the top and side locking structures. Although this method realizes the expansion of the battery, the stepped adjustment method lacks a tightening effect after fixation and is easily loosened due to external forces, affecting the stability and safety of the device.

[0006] In addition, there is also a design that realizes the expansion of the L-shaped battery through the bottom fixing slot, the top lock, and the structural fixation. Although this design solves the fixation problem to a certain extent, users need to operate with both hands to complete the pressing and disassembly of the battery during use, greatly reducing the convenience of use. At the same time, since the entire battery is stressed by the bottom and top structures simultaneously, it increases the risk of fracture of the locking structure during the reliability test, posing a threat to the overall durability of the product.

[0035] It should be further understood that the term " / and" as used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0036] Please refer toFigure 1-3 In this embodiment, a battery latch device is provided for cooperating with a host, including: a body 1, a positioning boss 2 is provided at one end of the body 1, a positioning groove 3 is provided in the positioning boss 2, a slide rail 4 is provided on the inner wall of the positioning groove 3, a battery latch structure 5 is provided on the outside of the positioning boss 2, and a cooperating rib position 6 is provided at the other end of the body 1; when one end of the host slides along the slide rail 4 into the positioning groove 3, one end of the host is connected to the battery latch structure 5, and the other end of the host is connected to the cooperating rib position 6.

[0037] The slide rail 4 and the cooperating rib position 6 of the present utility model are stressed, which can reduce the stress on the battery latch structure 5, provide good protection for the battery latch structure 5, and have high reliability. At the same time, both the slide rail 4 and the cooperating rib position 6 cooperate with the host, and the cooperation gap is easier to adjust than the latch cooperation and is not easy to loosen. The pressing direction is consistent with the battery release direction, and the operation is convenient.

[0038] In this embodiment, the body 1 includes: a battery front shell 7 and a battery bottom shell 8, the battery front shell 7 and the battery bottom shell 8 are connected, the positioning boss 2 is provided on the battery bottom shell 8, and the cooperating rib position 6 is provided on the battery front shell 7.

[0039] The design of the battery front shell 7 and the battery bottom shell 8 makes the assembly process more intuitive and simple. The factory can more easily achieve automated assembly during production, improving production efficiency. At the same time, when the battery needs maintenance or internal components need to be replaced, users or technicians can easily open the battery housing, perform operations and then re-seal it without completely disassembling the entire battery system.

[0040] Among them, the battery front shell 7 and the battery bottom shell 8 can be fixed by ultrasonic, or can be fixed by means such as adhesives, hot melting, screws, etc. The connection method or structure of the battery front shell 7 and the battery bottom shell 8 is not limited.

[0041] In this embodiment, please refer to Figure 3-6 , the battery latch structure 5 includes: a button 9 and an elastic member 10, the button 9 includes a latch 11, an installation groove 12 and a fixed rotating shaft 13, a rotating shaft groove 14 is provided on the positioning boss 2, the fixed rotating shaft 13 is rotatably installed in the rotating shaft groove 14, one end of the elastic member 10 is installed in the installation groove 12, there is a pressing space K between the button 9 and the positioning boss 2, the other end of the elastic member 10 is located in the pressing space K and abuts against the positioning boss 2, and the latch 11 is clamped with one end of the host.

[0042] The battery latch structure 5 is designed with a button 9, enabling users to operate it easily. When the user moves the main body into the positioning groove 3 and makes the clamping end of the main body engage with the latch 11, the main body is then connected to the battery latch device. When the user needs to separate the main body from the battery latch device, the user only needs to press the button 9. The button 9 rotates around the fixed rotating shaft 13, and at the same time, the elastic member 10 is compressed. When the pressing distance of the button 9 reaches the latching amount H1 (as shown in Figure 7 It should be noted that the set value of the latching amount H1 is not limited), and when it disengages a certain distance H2 in the reverse direction (as shown in Figure 8 ), the main body is separated from the battery latch device. When the user releases the hand, the elastic member 10 returns to its original state, and the latch 11 resets under the action of the elastic member 10. The whole process does not require complex operation steps or tools, greatly improving the user experience and the convenience of operation. Through the rotational installation of the fixed rotating shaft 13 in the rotating shaft groove 14, the button 9 can achieve a flexible rotational movement, thus adapting to different installation angles and positions.

[0043] In this embodiment, when the elastic member 10 is assembled and compressed, one end of the elastic member 10 will exert an outward pressure F on the button 9 (as shown in Figure 7 ). The outward pressure F is perpendicular to the battery release direction, and it is not easy to disengage during a fall, with high reliability.

[0044] In this embodiment, please refer to Figure 9 . The elastic member 10 includes a connected first elastic portion 15 and a second elastic portion 16. The first elastic portion 15 and the second elastic portion 16 are spaced apart to form a deformation cavity 17. The second elastic portion 16 arches toward the positioning boss 2. The first elastic portion 15 is installed in the installation groove 12, and the second elastic portion 16 abuts against the positioning boss 2.

[0045] The elastic member 10 is formed by connecting the first elastic portion 15 and the second elastic portion 16, and forms a deformation cavity 17 through spaced arrangement. This design enables the elastic member 10 to store energy more effectively when subjected to an external force and provide a more uniform and stable elastic force when released. The arching of the second elastic portion 16 toward the positioning boss 2 can increase the deformation amount of the elastic member 10, thereby enhancing the acting force of the elastic member 10 and further enhancing the connection strength between the main body and the battery latch device.

[0046] In this embodiment, please refer to Figure 10 . The button 9 further includes a button body 18. A plurality of mounting posts 19 are spaced apart on the side of the button body 18 close to the positioning boss 2. The installation groove 12 is provided between the mounting posts 19 and the button body 18. The latch 11 and the fixed rotating shaft 13 are respectively located at both ends of the button body 18, and the fixed rotating shaft 13 and the mounting posts 19 are on the same side, while the latch 11 and the mounting posts 19 are on different sides.

[0047] The design of the mounting post 19 is not only used for mounting the elastic member 10, but also plays a role in enhancing the stability of the button body 18. Through the tight fit between the mounting post 19 and the mounting groove 12, the button 9 can maintain good stability and rigidity when subjected to external forces, reducing the risk of loosening or damage caused by vibration or impact.

[0048] In this embodiment, a bent anti - detachment lug 20 is provided at one end of the first elastic portion 15 away from the second elastic portion 16 (as Figure 7 shown), and the anti - detachment lug 20 is snapped onto one of the mounting posts 19 to prevent the elastic member 10 from loosening.

[0049] The design of the anti - detachment lug 20 is an important stability measure. It is snapped onto the mounting post 19, effectively preventing the elastic member 10 from loosening due to vibration, impact or long - term use during the use process. This stability ensures that the elastic member 10 can continuously provide stable elastic force, thus guaranteeing the reliability and durability of the entire battery latch structure 5. At the same time, the design of the anti - detachment lug 20 simplifies the installation and disassembly process. During installation, simply abut the anti - detachment lug 20 against one of the mounting posts 19 to easily complete the installation; when maintenance or replacement is required, simply take the elastic member 10 directly to separate the elastic member 10 and the button 9, which is convenient and fast.

[0050] In this embodiment, fixing ribs 21 are provided on the first elastic portion 15 (as Figure 7 shown), and the fixing ribs 21 are arranged corresponding to the mounting posts 19.

[0051] To ensure that the elastic member 10 can be smoothly placed into the mounting groove 12, the length of the mounting groove 12 needs to be greater than the thickness of the first elastic portion 15. Therefore, when the first elastic portion 15 is installed into the mounting groove 12, there is a gap between the first elastic portion 15 and the mounting groove 12, so that the elastic member 10 is likely to shake after installation and thus detach from the mounting groove 12. However, the fixing ribs 21 in this embodiment can make the first elastic portion 15 always abut against the mounting groove 12 through deformation. The design of the fixing ribs 21 significantly enhances the connection strength between the first elastic portion 15 and the mounting post 19. Through the tight fit between the fixing ribs 21 and the mounting post 19, the elastic member 10 is more stable after installation and not easily loosened. This enhanced connection strength ensures that the elastic member 10 can maintain stable performance during long - term use, improving the reliability of the entire battery latch structure 5.

[0052] In this embodiment, an arc - shaped guiding portion 22 is provided at one end of the second elastic portion 16 away from the first elastic portion 15 (as Figure 7 shown), and the arc - shaped guiding portion 22 abuts against one of the mounting posts 19.

[0053] The design of the arc-shaped guiding part 22 enables users to feel a smoother and more seamless touch when pressing the button 9. It effectively reduces the resistance and abruptness during pressing, making the operation easier and more natural, and enhancing the user experience.

[0054] In this embodiment, please refer to Figure 7 , the button 9 further includes a first limiting part 23 disposed at the end of the button body 18, the fixed rotating shaft 13 is disposed at the end of the first limiting part 23 close to the positioning boss 2, and the positioning boss 2 is provided with a second limiting part 24 for restricting the outward turning of the first limiting part 23.

[0055] By restricting the outward turning of the first limiting part 23, the second limiting part 24 plays a role in protecting the button body 18 and the fixed rotating shaft 13. It reduces the wear and damage caused by external impact or vibration, thereby extending the service life of the button 9.

[0056] To prevent the button 9 from being over-pressed and causing the elastic member 10 to be unable to rebound, a third limiting part 25 (as shown in Figure 7 ) is provided on one side of the positioning boss 2 close to the button 9. Among them, the pressing space can be obtained by the inclined setting of the third limiting part 25, or can be obtained by the inclined setting of one side of the button 9 close to the third limiting part 25.

[0057] In this embodiment, the battery top case 7 and the battery bottom case 8 are detachably connected by screws 26 (as shown in Figure 3 ).

[0058] The connection by screws 26 can strengthen the bonding force between the battery top case 7 and the battery bottom case 8, prevent the battery from being loosened or disconnected from the battery top case 7 due to the force on the slide rail 4 of the battery bottom case 8, and improve the overall reliability of the battery locking device. When a fault occurs in the internal components of the battery, the detachable connection enables the battery locking device to replace only the faulty parts, thereby reducing waste and cost.

[0059] In this embodiment, the button 9 is provided with an anti-slip structure 27 (as shown in Figure 10 ). The anti-slip structure 27 can ensure that when the user uses the button 9, the fingers can firmly adhere to the surface of the button 9 and are not easily slipped. This stability not only improves the accuracy of the operation but also gives the user a more comfortable and secure use experience.

[0060] In this embodiment, a battery cell assembly 28 (as shown in Figure 3 ) is disposed inside the battery top case 7. As the core component of the battery, the performance of the battery cell directly affects the energy density of the entire battery. Disposing the battery cell assembly 28 inside the battery top case 7 can more effectively utilize the space, improve the energy density of the battery, and thus extend the battery life of the device.

[0061] In this embodiment, when the battery capacity needs to be expanded, it can be achieved by lengthening the bottom of the battery.

[0062] The assembly process of the battery buckle device in this embodiment is as follows:

[0063] 1. Assemble the battery cell assembly 28 and the battery face shell 7;

[0064] 2. Assemble the elastic member 10 into the button 9 to form the battery buckle structure 5;

[0065] 3. Fix the battery buckle structure 5 to the battery face shell 7 and the battery bottom shell 8 through a jig;

[0066] 4. Fix the battery face shell 7 and the battery bottom shell 8 by ultrasonic and lock them with two screws 26 to complete the assembly.

[0067] The battery buckle device in this embodiment has a simple structure, is convenient to assemble, has low cost, high efficiency, high reliability, and is suitable for a variety of materials. It can be designed as a standard part for L-shaped battery buckles. It can be applied to fields such as communication products, industrial equipment, and consumer products that require a detachable battery structure.
