[0023] This utility model proposes a battery box 100.

[0024] Please see Figures 1 to 4 In one embodiment of the present invention, the battery box 100 includes a box body with a cavity. The battery box 100 also includes a circuit board 3, a battery 1, and a plug-in assembly 2. The circuit board 3 is housed in the cavity. The battery 1 is housed in the cavity and spaced apart from the circuit board 3. The battery 1 has a plug-in port 11. The plug-in assembly 2 includes a plug-in member 21 and an elastic member 22 housed in the cavity. One end of the plug-in member 21 is electrically connected to the circuit board 3, and the end of the plug-in member 21 away from the circuit board 3 is plugged into and connected to the plug-in port 11. One end of the elastic member 22 is connected to the circuit board 3, and the end of the elastic member 22 away from the circuit board 3 abuts against the side of the plug-in member 21 facing away from the plug-in port 11.

[0025] In this embodiment, the battery box 100 can be applied to electronic devices including, but not limited to, aerosol generating devices. It should be noted that the box body is used to house the components of the entire battery box; to show the components inside the battery box 100, the box body is not shown here. (Combined with...) Figure 1 and Figure 4 The circuit board 3 here is a printed circuit board 3, which has multiple interfaces (not shown) for electrical connection with different components. It is understood that the circuit board 3 can be fixed to the inner bottom wall of the box by fasteners 4 such as bolts and rivets. Preferably, the bottom wall of the box protrudes to form two protruding pillars, which are located at opposite ends of the circuit board 3, and the connection and fixation between the circuit board 3 and the bottom wall of the box is achieved by bolts. The size of the battery 1 is slightly smaller than the size of the box so that the battery 1 is precisely confined within the cavity of the box. Specifically, in conjunction with... Figure 2The circuit board 3 and battery 1 are spaced apart, with a gap in between, so that the connector 2 is positioned between them to connect the circuit board 3 and battery 1. The end of battery 1 closest to circuit board 3 has a connector port 11, which is used for electrical connection between circuit board 3 and battery 1. The connector 21 is used to achieve the electrical connection between circuit board 3 and battery 1. It should be noted that the connector 21 here includes, but is not limited to, flexible materials such as flexible circuit board 3 or flexible cable connectors 21. Battery 1 is connected to the main board for power supply via flexible circuit board 3 or flexible cable. Battery 1 has a connector port 11, and connector 21 has a plug, which is plugged into connector port 11 to achieve electrical connection. To prevent connector 21 from detaching from connector port 11, one end of elastic member 22 abuts against the outside of connector 21 (the side of connector 21 facing away from connector port 11), and the end of elastic member 22 away from circuit board 3 abuts against connector 21, thereby providing elastic support and pressure for connector 21. It is understood that the form of the elastic element 22 includes, but is not limited to, a spring (metal spring or beryllium bronze spring), a silicone rubber elastic element 22, a silicone elastic element 22, etc., with the spring form being preferred here. Furthermore, since the electrical connection between the battery 1 and the circuit board 3 is achieved by inserting the connector 21 into the connector port 11, when disassembly is required, it is only necessary to remove the elastic element 22 to detach the connector 21 from the connector port 11, thereby removing the battery 1.

[0026] The technical solution of this utility model involves setting a plug-in assembly 2 between the battery 1 and the circuit board 3. The plug-in assembly 2 includes a plug 21 and an elastic member 22. The plug 21 is used to realize the electrical connection between the battery 1 and the circuit board 3, ensuring that the current can be stably transmitted between the battery 1 and the circuit board 3. The elastic member 22 abuts against the outside of the plug 21. Its elasticity can apply appropriate pressure to the contact between the plug 21 and the battery 1 plug-in port 11 and the circuit board 3, making the contact between the plug 21 and the contact surface of the battery 1 plug-in port 11 and the circuit board 3 tighter and effectively reducing the contact resistance. Furthermore, due to its elasticity, it can automatically adjust the pressure under external forces (such as vibration, thermal expansion and contraction, etc.) to maintain a good contact state, thereby ensuring the reliability of the electrical connection. Thus, when the plug 21 is subjected to external vibration, impact, etc., the elastic member 22 can maintain good contact between the plug 21 and the plug-in port 11 and the circuit board 3. Meanwhile, when it is necessary to disassemble the battery 1 from the circuit board 3, there is no need to disassemble the connector 21. Simply disassemble the elastic element 22 to quickly and easily separate the battery 1 from the connector 2, which greatly improves disassembly efficiency and reduces maintenance costs.

[0027] In one embodiment of the present invention, the elastic member 22 includes an abutting part and a connecting part. The abutting part is connected to the connecting part. The abutting part abuts against the side of the plug-in member 21 facing away from the plug-in port 11. The connecting part is connected to the circuit board 3.

[0028] In this embodiment, combined with Figure 3 Furthermore, to ensure the connector 21 remains in a stable position and state within the battery compartment, the elastic member 22 generates elastic force through its own elastic deformation. The abutment portion applies elastic pressure to the outside of the connector 21, and the connecting portion connects to the circuit board 3, transmitting the elastic force to the circuit board 3. This elastic force balances the reaction force generated by the connector 21 during connection with the battery 1's connector port 11, ensuring a tight fit between the connector 21 and the battery 1's connector port 11, while also ensuring good electrical contact between the connector 21 and the circuit board 3. This configuration not only improves assembly efficiency but also facilitates disassembly and replacement, reducing maintenance costs and time.

[0029] In one embodiment of the present invention, the abutting part includes a first abutting section 221, a first connecting section 222 and a second abutting section 223. The two ends of the first connecting section 222 are respectively connected to the first abutting section 221 and the second abutting section 223. The first abutting section 221 protrudes from the first connecting section 222 and abuts against the side of the plug-in member 21 facing away from the plug-in port 11. The end of the first connecting section 222 near the circuit board 3 is bent to form the second abutting section 223. The second abutting section 223 abuts against the periphery of the circuit board 3.

[0030] In this embodiment, in order to enhance the connection stability of the elastic element 22, combined with Figure 3 The elastic element 22 provided in this application is U-shaped. It is understood that the first abutting section 221 protrudes from the side of the connector 21 facing away from the insertion port 11, thereby pressing the connector 21. The first connecting section 222 connects the first abutting section 221 and the second abutting section 223 together, forming an integral elastic support structure. When the connector 21 is connected to the battery 1 insertion port 11, the resulting reaction force is transmitted through the first abutting section 221 to the elastic element 22, and then through the first connecting section 222 and the second abutting section 223 to the circuit board 3, achieving force balance and maintaining the stable position of the connector 21. The first abutting section 221 and the second abutting section 223 apply elastic pressure to the side of the connector 21 facing away from the insertion port 11 and the periphery of the circuit board 3, respectively, ensuring a tight fit between the connector 21 and the battery 1 insertion port 11, while also ensuring good electrical contact between the connector 21 and the circuit board 3, achieving a stable electrical connection.

[0031] In one embodiment of the present invention, the first connecting segment 222 protrudes along the radial direction of the battery 1, and a gap is formed between the first abutting segment 221 and the second abutting segment 223.

[0032] In this embodiment, combined with Figure 3 Because the first connecting segment 222 protrudes radially, the elastic element 22 provides support not only in the axial direction (the length direction of the battery 1) but also in the radial direction. It should be noted that the protruding shape can be, but is not limited to, an arc shape, or even a U-shape; an arc shape is preferred here. The gap between the first abutting segment 221 and the second abutting segment 223 provides a certain amount of space for the connector 21 and the elastic element 22 to move. When the battery box is subjected to external impact or vibration, the connector 21 can undergo slight displacement within the gap range. The elastic element 22 buffers and absorbs the external force through its own elastic deformation, thereby protecting the connector 21 and the battery 1's connection port 11 from damage. This arrangement allows the connector 21 to move freely within a certain range, thus absorbing the external force through the deformation of the elastic element 22 when the battery box is subjected to vibration or shaking, further enhancing the stability of the connection.

[0033] In one embodiment of the present invention, the connecting part includes a second connecting segment 224, and the abutting part includes a first connecting segment 222. The first connecting segment 222 extends to form the second connecting segment 224 near the end of the circuit board 3. The second connecting segment 224 has a through hole 22a. The battery box also includes a fastener 4, which passes through the through hole 22a, the circuit board 3 and the plug-in 21 in sequence and is fixed.

[0034] To improve connection reliability, combined with Figure 2 and Figure 4 In this embodiment, fasteners 4 are used to secure the elastic element 22, circuit board 3, and connector 21. It should be noted that the type of fastener 4 includes, but is not limited to, screws and bolts, etc., and is not limited here. The size of the fastener 4 is adapted to the size of the through hole 22a. The fastener 4 (such as screws or bolts) secures the elastic element 22 and circuit board 3 together tightly through threaded connection or snap-fit ​​with the connector 21. When the fastener 4 passes through the through hole 22a of the second connecting section 224 and is screwed into or snap-fitted into the connector 21, an axial clamping force is generated, forming a tight mechanical connection between the elastic element 22, circuit board 3, and connector 21, preventing relative movement between components and thus ensuring the reliability of the connection.

[0035] In one embodiment of the present invention, the end of the second connecting segment 224 near the through hole 22a is bent toward the periphery of the circuit board 3 to form a third abutting segment 225, and the third abutting segment 225 abuts against the periphery of the circuit board 3.

[0036] In this embodiment, combined with Figure 3To further enhance connection stability, the third abutment section 225 abuts against the periphery of the circuit board 3, further strengthening the connection stability between the elastic element 22 and the circuit board 3. This multi-point abutment method allows the elastic element 22 to be more firmly fixed to the circuit board 3, preventing loosening of the connection due to vibration or shaking, and ensuring stable and reliable electrical connections between the components inside the battery box.

[0037] In one embodiment of the present invention, the second connecting section 224 has a plurality of spaced through holes 22a; the battery box also includes a plurality of fasteners 4, each fastener 4 passing through a through hole 22a, the circuit board 3 and the connector 21 in sequence for fixing.

[0038] In this embodiment, combined with Figure 4 It is understandable that, in order to further enhance the reliability and stability of the battery box connection structure, multiple fasteners 4 pass through multiple through holes 22a and are fixed to the plug 21, making the connection between the elastic element 22 and the circuit board 3 and the plug 21 more secure, dispersing the stress at the connection, and reducing the risk of connection loosening caused by single-point fastening.

[0039] In one embodiment of this utility model, the plug 21 and the elastic member 22 are both located between the circuit board 3 and the battery 1, and the plug 21 and the elastic member 22 are staggered along the radial direction of the battery 1.

[0040] In this embodiment, to optimize the spatial layout and avoid the connector 21 and elastic member 22 occupying too much space in the axial direction of the battery 1, the connector 21 and elastic member 22 are staggered along the radial direction of the battery 1. It should be noted that the connector 21 and elastic member 22 can be arranged on the same side (i.e., simultaneously positioned above or below) or on opposite sides (i.e., one positioned above and the other below), with the opposite side arrangement being preferred here. The opposite side arrangement of the connector 21 and elastic member 22 allows for support and constraint of the connector 21 and the battery 1's connection port 11 from different directions. This multi-point support enhances the connection stability between the connector 21, the battery 1's connection port 11, and the circuit board 3, maintaining a stable position of the connector 21 within the battery compartment, reducing displacement or shaking caused by external forces, and ensuring the reliability of the electrical connection.

[0041] In one embodiment of the present invention, the end of the plug 21 near the circuit board 3 is connected to the lower surface of the circuit board 3, and the end of the elastic member 22 near the circuit board 3 is connected to the upper surface of the circuit board 3.

[0042] In this embodiment, it should be noted that, in conjunction with Figure 1 and Figure 2To distribute stress, the connector 21 and the elastic element 22 are connected to the circuit board 3 on the upper and lower sides respectively, forming a top-and-bottom support structure. When the battery box is subjected to external force or vibration, the stress can be distributed on the upper and lower sides of the circuit board 3, avoiding excessive stress concentration on one side, thereby reducing the risk of loosening or damage to the connection due to stress concentration and improving the stability of the entire connection structure. At the same time, assembly can be performed from the bottom and top of the battery box respectively, eliminating the need for complex stacking and alignment operations in the axial direction, reducing assembly difficulty, improving assembly efficiency, and facilitating automated assembly.

The battery box 100 is housed within the inner cavity of the outer casing in a manner including, but not limited to, designing a snap-fit ​​protrusion at the opening of the inner cavity and a corresponding slot on the battery box 100. When the battery box 100 is inserted into the inner cavity, the snap-fit ​​protrusion engages with the slot to secure the battery box 100. Simultaneously, an elastic snap-fit ​​electrical connection piece is provided at the electrical connection end of the battery box 100. When the battery box 100 is fully inserted, the electrical connection piece automatically springs up and engages with the corresponding connection point on the device circuit board. Alternatively, an internal thread is provided at the opening of the inner cavity, and a matching external thread is provided on the outer side of the battery box 100. The battery box 100 is secured by rotating the threads to interlock.
