Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a switching assembly and a battery pack. Background Technology

[0002] Push-button switches are a common and important control component in battery packs, electronic devices, and various electrical installations, widely used for power on / off switching and mode changing. These switches typically achieve circuit on / off control by manually pressing an internal electrical contact mechanism. They offer advantages such as simple structure, intuitive operation, and rapid response, making them a fundamental component for human-machine interaction. Push-button switches are particularly prevalent in devices requiring frequent start-stop management, such as slave-controlled battery packs, due to their high reliability and low cost.

[0003] However, in actual use, these exposed push-button switches are prone to accidental activation. Especially in mobile use, equipment vibration, or confined installation environments, the battery pack may be accidentally triggered due to pressure, impact, or unintentional physical contact by the operator. Such unintentional operation may cause abnormal shutdown or restart of the battery pack, not only affecting the continuous operation of the equipment but also potentially impacting the battery management system (BMS) and battery cells due to frequent abnormal power outages, accelerating battery aging, and even causing safety issues, thereby increasing the maintenance costs and usage risks of the equipment. Utility Model Content

[0004] This application provides a switch assembly and battery pack that reduce the risk of accidental button presses, improve safety, and facilitate installation and disassembly, thereby at least partially solving the aforementioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, a switching assembly is provided, comprising:

[0006] A protective frame includes a protective part and a connecting part. The protective part has a through hole that extends through both sides of the protective part. The connecting part is connected to one side of the protective part. The end of the connecting part away from the protective part has a buckle that protrudes from the side of the connecting part away from the through hole.

[0007] A button for performing a switch operation, the button being movably inserted through the through hole;

[0008] The connecting part is configured to pass through the mounting hole on the mounting panel, such that the protective part and the buckle abut against opposite sides of the mounting panel to fix the protective frame to the mounting panel. In the direction away from the mounting panel, the side of the protective part away from the mounting panel extends beyond the side of the button away from the mounting panel, or the side of the protective part away from the mounting panel is flush with the side of the button away from the mounting panel.

[0009] Optionally, the connecting portion includes a first segment and a second segment, the first segment connecting the protective portion and the second segment, the second segment being inclined away from the through hole in a direction away from the protective portion, and the fastener being provided on the second segment.

[0010] Optionally, the buckle has a first guide slope, which is located on the side of the buckle opposite to the protective part. The first guide slope is used to cooperate with the inner wall of the mounting hole, so that the connecting part elastically deforms towards the center of the through hole when it is inserted into the through hole; and / or,

[0011] The buckle has a second guide slope, which is located on the side of the buckle facing the protective part. The second guide slope is used to cooperate with the inner wall of the mounting hole so that when the connecting part is inserted into the through hole, it resets in a direction away from the center of the through hole.

[0012] Optionally, the protective part includes a first end and a second end, the first end surrounding the outer periphery of the through hole, and in the direction away from the mounting panel, the side of the first end opposite to the mounting panel extends beyond the side of the button opposite to the mounting panel.

[0013] The second end extends obliquely from the first end toward a direction away from the through hole and toward the mounting panel.

[0014] Optionally, multiple connecting portions are provided, and the multiple connecting portions are arranged at intervals along the circumference of the through hole.

[0015] Optionally, the button includes a main body and a limiting part, the main body being movably disposed through the through hole, the limiting part being protruding from the outer periphery of the main body, and the limiting part being configured to be located on the side of the mounting panel opposite to the protective part.

[0016] Optionally, the limiting portion extends along the outer periphery of the main body portion, and the limiting portion is located on the side of the buckle portion away from the protective portion.

[0017] Optionally, the switch assembly includes a connector configured to be mounted on a printed circuit board assembly. One of the button and the connector has a protrusion, and the other has a recess. The recess and the protrusion engage to achieve a detachable connection between the button and the connector.

[0018] Optionally, the minimum distance between the side of the protective part facing away from the mounting panel and the side of the button facing away from the mounting panel is between 0 mm and 1 mm.

[0020] In the switch assembly of this application embodiment, a protective frame with a protective part and a connecting part is provided. The button is movably inserted into the through hole of the protective part and confined in a direction away from the mounting panel. The side of the protective part away from the mounting panel extends beyond or is flush with the corresponding end face of the button, thereby effectively shielding and limiting the button in terms of physical structure. This prevents fingers, tools, or other objects from directly pressing or scratching the button without intentional intent, significantly reducing the risk of accidental switch triggering due to squeezing, collision, or misoperation, and improving safety and reliability during use. At the same time, the end of the connecting part away from the protective part has a protruding buckle.

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] Please see Figures 1 to 3This application provides a switch assembly 100, which is used to be disposed in a mounting panel 200. The switch assembly 100 includes a protective frame 1 and a button 2. The protective frame 1 includes a protective part 11 and a connecting part 12, which can be integrally injection molded or separate structures. The protective part 11 is an annular closed structure with a through hole 1101 in the middle. The connecting part 12 is connected to one side of the protective part 11, and a buckle 121 is provided at the end of the connecting part 12 opposite to the protective part 11. The buckle 121 protrudes from the side of the connecting part 12 opposite to the through hole 1101. The button 2 is used to perform switch operation. The button 2 is disposed in the through hole 1101 and movably passes through the through hole 1101. The connecting part 12 is configured to pass through a mounting hole 210 on the mounting panel 200, so that the protective part 11 and the buckle 121 respectively abut against opposite sides of the mounting panel 200 (e.g., Figure 3 As shown, the upper and lower surfaces are parallel to each other to fix the protective frame 1 to the mounting panel 200. To further enhance the fixing effect of the protective frame 1 on the mounting panel 200, the outer perimeter of the protective part 11 away from the through hole 1101 is greater than the perimeter of the mounting hole 210, thereby ensuring that the protective frame 1 is firmly fixed to the mounting panel 200. In the direction away from the mounting panel 200, the side of the protective part 11 away from the mounting panel 200 extends beyond the side of the button 2 away from the mounting panel 200, or the side of the protective part 11 away from the mounting panel 200 is flush with the side of the button 2 away from the mounting panel 200 (i.e., Figure 3 In the middle, the upper surface of the protective part 11 is higher than or flush with the upper surface of the button 2.

[0035] In the technical solution of this application, by setting a protective frame 1 with a protective part 11 and a connecting part 12, the button 2 is movably inserted into the through hole 1101 of the protective part 11 and confined in a direction away from the mounting panel 200. The side of the protective part 11 away from the mounting panel 200 extends beyond or is flush with the corresponding end face of the button 2, thereby effectively shielding and limiting the button 2 in terms of physical structure, preventing fingers, tools or other objects from directly pressing or scratching the button 2 without subjective intent, significantly reducing the risk of accidental triggering of the switch due to squeezing, collision or misoperation, and improving the safety and reliability during use; at the same time, the end of the connecting part 12 away from the protective part 11 is provided with a protruding buckle 121. When the connecting part 12 passes through the mounting hole 210 on the mounting panel 200, the protective part 11 and the buckle 121 respectively abut against the two sides of the mounting panel 200 to form a stable clamping fixation. The protective frame 1 can be quickly installed and disassembled without the need for additional screws or buckles, which greatly simplifies the assembly process and improves the convenience of maintenance. In summary, the switch assembly 100 reduces the risk of accidental button 2 activation and improves safety by using the protective part 11 to block and limit the button 2, and by using the snap-fit ​​structure formed in conjunction with the snap-fit ​​part 121, and is also easy to install and remove.

[0036] It should be noted that the side of button 2 facing away from the mounting panel 200 is formed as an operating surface for the user to press. During the operation of the switch, button 2 can reciprocate between its original position and fully pressed position along the pressing direction, and the position of its operating surface changes dynamically accordingly. In this application, "the side of the protective part 11 facing away from the mounting panel 200 extends beyond the side of button 2 facing away from the mounting panel 200, or is flush with it" means that when button 2 is in its original unpressed state, the side of the protective part 11 facing away from the mounting panel 200 is higher than or flush with the operating surface of button 2; under this condition, when button 2 is fully pressed to its limit position, the side of the protective part 11 facing away from the mounting panel 200 is still higher than the operating surface of button 2. Therefore, the protective part 11 can effectively limit and physically shield the operating surface of button 2 throughout its entire stroke range, preventing external objects from accidentally touching, scratching, or excessively pressing button 2 from the side or at an angle, ensuring that the switch operation can only be triggered when the user intentionally applies vertical force.

[0037] Please see Figure 3 and Figure 4 In some embodiments, the connecting portion 12 includes a first segment 122 and a second segment 123. The first segment 122 connects the protective portion 11 and the second segment 123. In the direction away from the protective portion 11, the second segment 123 is inclined away from the through hole 1101, and the fastener 121 is provided on the second segment 123. In these embodiments, the inclined second segment 123 causes the fastener 121 to be offset outward relative to the center of the through hole 1101. When the connecting portion 12 passes through the mounting hole 210 on the mounting panel 200, the fastener 121 interferes with the edge of the mounting hole 210 and undergoes elastic deformation. After passing through the hole, it returns to its original shape, thus achieving locking. Because the second segment 123 has an outwardly flared, inclined structure, it can form a larger contact span and clamping torque with the back of the mounting panel 200 when locked, significantly enhancing the connection stability between the protective frame 1 and the mounting panel 200 and effectively preventing loosening or detachment due to vibration or external pulling. Simultaneously, this inclined structure provides a convenient force point for disassembly operations; by applying force to the inclined surface of the second segment 123 with a tool, it can be deformed inward, thereby quickly releasing the fastener and achieving convenient disassembly. Therefore, this design improves the maintenance convenience of the switch assembly 100 while ensuring reliable fixation.

[0038] Please see Figure 4In some embodiments, the buckle 121 has a first guide slope 1211, which is located on the side of the buckle 121 away from the protective part 11. The first guide slope 1211 is used to cooperate with the inner wall of the mounting hole 210 so that the connecting part 12 elastically deforms toward the center of the through hole 1101 when it is inserted into the through hole 1101. In these embodiments, when the connecting part 12 begins to be inserted into the mounting hole 210 on the mounting panel 200, the first guide slope 1211 at the front end of the buckle 121 first contacts the inner wall of the mounting hole 210. The first guide slope 1211 can decompose the reaction force applied to the inner wall of the mounting hole 210 into an axial force and a radially inward component force, thereby guiding the second segment 123 to generate elastic deformation toward the center of the through hole 1101, so that the connecting part 12 drives the buckle 121 to retract and smoothly pass through the mounting hole 210. This design effectively reduces the insertion force during the initial stage of assembly, improves centering and assembly smoothness, and is especially helpful for achieving fast and labor-saving installation operations in situations where space is limited or vision is inconvenient.

[0039] Please see Figure 4 In some embodiments, the fastener 121 has a second guide slope 1212, which is located on the side of the fastener 121 facing the protective portion 11. The second guide slope 1212 is used to engage with the inner wall of the mounting hole 210, so that when the connecting portion 12 is inserted into the through hole 1101, it returns to its original position away from the center of the through hole 1101. In these embodiments, when the connecting portion 12 is inserted into the mounting hole 210 and is nearly complete, the fastener 121 gradually protrudes from the back of the mounting panel 200, and the second guide slope 1212 at its rear edge contacts the inner wall of the mounting hole 210. Because the second guide slope 1212 has an inclined transition profile, the contact with the inner wall of the mounting hole 210 changes from a surface or line contact with right angle edges to a smooth point or progressive contact. This effectively avoids rigid jamming and edge scratching, reduces the lateral frictional resistance during the insertion of the buckle 121, and reduces additional compression on the elastic structure of the connecting part 12. This allows the connecting part 12 to more quickly and completely return to its original open state based on its own elasticity after the buckle 121 is released from the constraint of the mounting hole 210. During this process, the clamping action of the buckle 121 and the protective part 11 on both sides of the mounting panel 200 is reliably established, thereby ensuring that the switch assembly 100 is firmly fixed on the mounting panel 200, improving the smoothness of the assembly process and the stability of the final connection.

[0040] Please see Figure 4In some embodiments, the buckle 121 has a first guide slope 1211 and a second guide slope 1212. The first guide slope 1211 is located on the side of the buckle 121 away from the protective part 11. The first guide slope 1211 is used to cooperate with the inner wall of the mounting hole 210 so that the connecting part 12 elastically deforms toward the center of the through hole 1101 when it is inserted into the through hole 1101. The second guide slope 1212 is located on the side of the buckle 121 facing the protective part 11. The second guide slope 1212 is used to cooperate with the inner wall of the mounting hole 210 so that the connecting part 12 resets toward the center of the through hole 1101 when it is inserted into the through hole 1101. In these implementations, a first guide ramp 1211 is located at the front end of the buckle 121 (on the side opposite to the protective part 11) to guide the buckle 121 to deform inward under pressure during initial insertion, achieving smooth insertion. A second guide ramp 1212 is located at the rear end of the buckle 121 (facing the protective part 11) to prevent scraping or jamming with the edge of the mounting hole 210 during the insertion process, providing a clearance channel. The two work together to form an optimized insertion-exit path at both ends, significantly reducing the insertion force and operating resistance throughout the assembly process, preventing structural damage, and ensuring that the buckle 121 can smoothly spring back and lock after insertion, thereby achieving highly efficient and reliable tool-free installation.

[0041] In other embodiments of this application, in order to maintain the uniformity of the buckle 121 structure, the areas of the first guide slope 1211 and the second guide slope 1212 are approximately the same.

[0042] Please see Figure 4In some embodiments, the protective portion 11 includes a first end 111 and a second end 112. The first end 111 surrounds the outer periphery of the through hole 1101, and in a direction away from the mounting panel 200, the side of the first end 111 facing away from the mounting panel 200 extends beyond the side of the button 2 facing away from the mounting panel 200. The second end 112 extends obliquely from the first end 111 in a direction away from the through hole 1101 and close to the mounting panel 200. In these embodiments, the protective portion 11 includes a first end 111 and a second end 112, wherein the first end 111 surrounds the outer periphery of the through hole 1101 and extends beyond the operating end face of the button 2 in a direction away from the mounting panel 200, thus physically shielding the button 2 and effectively preventing accidental contact of the button 2 by fingers, tools, or foreign objects from the side or at an angle, significantly reducing the risk of malfunction due to accidental pressing. The second end 112 extends obliquely from the first end 111, unfolding in a direction away from the through hole 1101 and close to the mounting panel 200, and finally its edge abuts against the surface of the mounting panel 200. The protective part 11 forms an inclined support structure, which increases the span of the lever arm between the protective part 11 and the mounting panel 200, thereby improving the overall stability of the installation. In addition, the protective part 11 forms a thin-walled inclined structure, which, while meeting the requirements of protection and structural clamping, avoids the material waste caused by increasing the overall height or thickness, and helps to reduce weight, reduce the difficulty of injection molding, and reduce the risk of shrinkage and deformation.

[0043] Please see Figure 4 In some embodiments, multiple connecting portions 12 are provided, and the multiple connecting portions 12 are arranged at intervals along the circumference of the through hole 1101. In these embodiments, multiple connecting portions 12 are provided (four are shown in the figure, but there can also be two, three, five or other numbers), and the multiple connecting portions 12 are arranged at intervals along the circumference of the through hole 1101. This arrangement makes the connection between the protective part 11 and the mounting panel 200 circumferentially multi-point fixed, which significantly enhances the stability of the connection. During assembly, each connecting portion 12 can undergo elastic deformation simultaneously to achieve one-time press installation; during disassembly, only the unlocking force needs to be applied simultaneously to disengage the entire assembly, which is simple to operate and easy to maintain. Multiple connecting portions 12 share the force during installation and disassembly, effectively dispersing stress and avoiding excessive load on a single clip, thereby reducing the risk of deformation, loosening or fatigue damage caused by stress concentration. This design maintains a simple structure while taking into account high connection strength and good ease of assembly and disassembly, which helps to improve the overall reliability and user experience of the switch assembly 100.

[0044] In some embodiments, the plurality of connecting portions 12 are evenly arranged circumferentially along the through hole 1101, which is beneficial to the balanced distribution of stress and further improves the stability of the connection and the durability of the structure.

[0045] Understandably, the buckle 121 protrudes from the side of the connecting part 12 opposite to the through hole 1101. When multiple connecting parts 12 are provided and arranged at intervals along the circumference of the through hole 1101, multiple buckles 121 are also provided accordingly, forming a circumferential multi-point fastening, which significantly enhances the locking stability between the protective frame 1 and the mounting panel 200 and prevents loosening or rotation.

[0046] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the button 2 includes a main body 21 and a limiting part 22. The main body 21 is movably disposed through the through hole 1101, and the limiting part 22 protrudes from the outer periphery of the main body 21. The limiting part 22 is configured to be located on the side of the mounting panel 200 opposite to the protective part 11. In these embodiments, the side of the main body 21 opposite to the mounting panel 200 forms the operating end face of the button 2, and the limiting part 22 limits the axial position of the button 2 to prevent it from falling out of the mounting panel 200. The positioning of the limiting part 22 ensures that after the button 2 is assembled, the operating end face is within the shielding range of the protective part 11, effectively preventing accidental activation and improving the reliability and safety of the switch assembly 100.

[0047] Understandably, the portion of the connecting part 12 (the portion with the latch 121) is located on the side of the mounting panel 200 opposite to the protective part 11, and the limiting part 22 is also configured to be located on the side of the mounting panel 200 opposite to the protective part 11. In some embodiments, the two can be staggered, with the latching portion of the connecting part 12 avoiding the limiting part 22, so that during the movement of the button 2, the limiting part 22 can directly abut against the corresponding position of the mounting panel 200, thereby realizing its limiting function.

[0048] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the limiting part 22 extends along the outer periphery of the main body 21 and is located on the side of the buckle 121 opposite to the protective part 11. In these embodiments, the limiting part 22 directly abuts against the buckle 121 during the movement of the button 2, forming an axial stop with the buckle 121 to achieve a reliable limiting function. This design eliminates the need to ensure that the limiting part 22 and the connecting part 12 are staggered, avoiding the positional alignment requirements during assembly, simplifying the assembly process, and improving assembly efficiency. In addition, the limiting part 22 can be continuously set as a full circle in the circumferential direction, with a large force-bearing area, which is beneficial to improving structural strength and load-bearing capacity. During the limiting process, the limiting part 22 applies axial pressure to the buckle 121, making the connection between the protective frame 1 and the mounting panel 200 tighter, further enhancing the overall stability of the protective frame 1.

[0049] Please see Figure 7In some embodiments, the switch assembly 100 includes a connector 3 configured to be mounted on a printed circuit board assembly (PCBA board). One of the button 2 and the connector 3 has a protrusion, and the other has a recess. In this embodiment, the connector 3 has a protrusion, while the button 2 has a recess 211 (see...). Figure 2 The diagram illustrates that button 2 has a recess 211, which engages with a protrusion to achieve a detachable connection between button 2 and connector 3. In these embodiments, the engagement of the protrusion and recess 211 forms a reliable mechanical connection between button 2 and connector 3, while facilitating assembly and disassembly. This design allows button 2 to reliably transmit force to connector 3 when pressed, thereby triggering the switching element on the PCBA board, ensuring accurate signal transmission and sensitive response. By making button 2 and connector 3 detachably connected, it not only facilitates step-by-step assembly during production but also makes it easier to maintain or replace button 2 later, improving the versatility and maintainability of switch assembly 100. Furthermore, the snap-fit ​​structure eliminates the need for additional fasteners, simplifying the number of parts, reducing manufacturing costs, and avoiding the risk of connection failure due to loose screws.

[0050] Please see Figure 3 In some embodiments, the minimum distance between the side of the protective part 11 facing away from the mounting panel 200 and the side of the button 2 facing away from the mounting panel 200 is between 0 mm and 1 mm. Figure 3 In this context, h represents the minimum distance. It should be noted that the side of button 2 facing away from the mounting panel 200 forms an operating surface for user pressing. During switch operation, button 2 can reciprocate between its original position and fully pressed position along the pressing direction, dynamically changing the position of its operating surface. Consequently, the distance between the side of the protective part 11 facing away from the mounting panel 200 and the operating surface also changes. When button 2 is in its original, unpressed state, the distance is minimal; when button 2 is pressed and moves downwards, the distance increases. Therefore, in this application, "minimum distance" refers to the distance between the side of the protective part 11 facing away from the mounting panel 200 and the operating surface when button 2 is in its original state (unpressed). The aforementioned 0mm to 1mm range defines the spacing in the initial state: when the spacing is 0mm, the protective part 11 is flush with the operating end face, allowing the user to clearly identify the pressing position and operate conveniently, while still effectively blocking laterally inserted foreign objects; when the spacing is close to 1mm, the protective part 11 is slightly higher than the operating end face, forming a slight obstruction, further enhancing the ability to prevent accidental touches. This size range ensures the effectiveness of protection while avoiding inconvenience or decreased tactile feedback caused by excessive indentation of the button 2, ensuring normal operation in the vertical direction, achieving a good balance between safety and operability, and improving the overall reliability and user experience of the switch assembly 100.

[0051] This application also provides a battery pack, which includes a switch assembly 100. The structure of the switch assembly 100 is as described above. Because the switch assembly 100 has excellent anti-accidental contact capability, it can effectively prevent abnormal start-up and shutdown of the battery pack due to accidental contact during use, improve system operational stability, and reduce battery wear and maintenance costs caused by misoperation. This design is simple in structure, safe and reliable, and suitable for battery application scenarios with high safety requirements, possessing good practicality and promotional value.
