[0039] like Figures 1 to 3 As shown, the battery module provided in this embodiment further includes a battery cover 30 and a main control board cover 40, which are detachably connected to the bracket 20, respectively, and cover the notches of the battery accommodating groove 201 and the main control board accommodating groove 202, respectively, to fix the position of the battery 1 and the main control board 3. In this embodiment, the notch of the battery accommodating groove 201 and the notch of the main control board accommodating groove 202 are located on the same side of the bracket 20.

[0040] Specifically, an opening 204 is provided at the bottom of the battery accommodating groove 201 , through which the back of the battery 1 can be pressed against to allow the battery 1 to be smoothly removed from the notch of the battery accommodating groove 201 .

[0044] like Figure 3 and Figure 4 As shown, the battery module provided in this embodiment also includes an elastic conductive sheet 2, and the battery 1 is electrically connected to the main control board 3 through the elastic conductive sheet 2. One end of the elastic conductive sheet 2 is fused to the battery 1, and the other end is fused to the main control board 3.

[0045] In the battery module provided by this embodiment, the battery 1 is electrically connected to the main control board 3 through the elastic conductive sheet 2, so that the circuit of the battery 1 and the main control board 3 is connected. The elastic conductive sheet 2 is fused with the battery 1, and the other end is fused with the main control board 3. Both ends of the elastic conductive sheet 2 are connected by welding, which saves the use of tin materials and effectively reduces the cost of materials. Moreover, when there is a position error or thermal expansion and contraction between the battery 1, the main control board 3 and the elastic conductive sheet 2, the elastic conductive sheet 2 can be adaptively deformed elastically, thereby ensuring the firmness of the contact point connection. At the same time, the end of the elastic conductive sheet 2 is easy to position, and the welding with the battery 1 and the main control board 3 can be performed by automated equipment, thereby improving production efficiency.

This configuration makes the elastic conductive sheet 2 elastic.

[0048] More specifically, the inner wall of the elastic avoidance groove 21 is provided with a through groove 22. The provision of the through groove 22 reduces the rigidity of the elastic conductive sheet 2 at the elastic avoidance groove 21 and increases the elasticity of the elastic conductive sheet 2. Figure 4 As shown, two through grooves 22 are provided at the elastic avoidance groove 21 .

[0049] like Figure 5 As shown, the battery module provided in this embodiment also includes a charging connector 5 and an electrical connector 6.

The charging connector 5 is electrically connected to the main control board 3 through the electrical connector 6. One end of the electrical connector 6 elastically abuts against the main control board 3, and the other end is connected to the charging connector 5. One end of the electrical connector 6 elastically abuts against the main control board 3, thereby avoiding the loosening of the contact due to position error and thermal expansion and contraction of the material. The tail end of the charging connector 5 faces the battery 1, and the head of the charging connector 5 is provided with a charging port, which is exposed outside the bracket 20 and is used to charge the battery 1.

In this embodiment, the elastic abutment 61 is in a U-shaped structure. The end of the elastic abutment end 611 is plugged into the main control board 3 and fused with the main control board 3, which not only ensures the firmness of the connection, but also reduces the cost because no tin material is required.

[0052] More specifically, the side wall of the main body 62 is provided with a plurality of locking protrusions 621, and the inner wall of the electrical connector accommodating groove 205 of the bracket 20 is provided with a plurality of locking grooves, and the plurality of locking protrusions 621 and the plurality of locking grooves are correspondingly engaged. Such an arrangement ensures the firmness of the fixing of the electrical connector 6.

[0053] More specifically, the electrical connector 6 further includes a fixing portion 63 , which is connected to an end of the main body 62 away from the elastic abutment 61 , and is fastened to the charging connector 5 by a fastener 64 such as a bolt or a screw.

The component to be powered can be an atomization bin or other actuator that needs power. Since the tail of the spring contact terminal 9 is elastically clamped in the elastic fixing member 8, loose contacts caused by position errors and thermal expansion and contraction of materials are avoided.

[0055] Specifically, the elastic fixing member 8 includes a bottom plate 81 and two side plates 82 connected to a U-shaped structure, both side plates 82 are connected to the main control board 3, and both side plates 82 are provided with elastic clamping plates 821.

The bottom plate 81 and the two side plates 82 are connected to form a U-shaped structure, which defines the position of the tail of the spring contact terminal 9. The two elastic clamping plates 821 realize the elastic clamping of the spring contact terminal 9.

[0056] More specifically, the end of the side plate 82 is plugged into the main control board 3 and welded to the main control board 3, which ensures the firmness of the connection and saves tin material and cost.

[0057] Optionally, in other embodiments, one end of the elastic clamp 821 is connected to the inner wall of the side plate 82, and the other end is a free end, which extends obliquely inward. When the tail of the spring contact terminal 9 is inserted, the free ends of the two elastic clamps 821 are pressed against each other and elastically deformed. The two elastic clamps 821 clamp the tail of the spring contact terminal 9 under the action of the elastic restoring force.

[0058] Specifically, in this embodiment, the side plate 82 is provided with an escape groove 822, one end of the elastic clamping plate 821 is connected to the inner wall of the escape groove 822, and the other end is a free end, and the free end extends obliquely toward the inside, extending out of the escape groove 822, and entering the U-shaped groove of the elastic fixing member 8 to abut against the tail of the spring contact terminal 9, and the two elastic clamping plates 821 clamp the tail of the spring contact terminal 9. With such a structure, during manufacturing, a part can be cut out of the side plate 82, and the part is bent inward to form the elastic clamping plate 821, and the exposed through groove is the escape groove 822. This structure is easy to manufacture and saves materials, and the existence of the escape groove 822 makes the elastic deformation range of the elastic clamping plate 821 large.

[0059] More specifically, the ends of the side plate 82 and the bottom plate 81 facing the head of the spring contact terminal 9 are bent toward opposite sides to form an introduction flange 823, which serves as a guide to facilitate the insertion of the tail of the spring contact terminal 9.

[0060] like Figure 5 As shown, the battery module provided in this embodiment further includes an anti-vibration pad 7, which is arranged between the charging connector 5 and the battery 1. The anti-vibration pad 7 can reduce the vibration of the battery 1 and prevent abnormal noise caused by the vibration.

[0061] Specifically, the elastic conductive sheet 2 is made of iron. Compared with the copper wire in the prior art, the cross-sectional area of ​​the elastic conductive sheet 2 is increased and the conductivity is enhanced. Therefore, the elastic conductive sheet 2 is made of iron without affecting the conductivity and greatly reducing the cost. In this embodiment, the elastic conductive sheet 2 is made of tinplate.

[0063] Specifically, Figure 5 As shown, a first magnet 43 is provided between the bracket 20 and the spring contact terminal 9. Correspondingly, an iron block or a second magnet that cooperates with the first magnet 43 for adsorption is provided on the component to be powered. When the component to be powered is docked with the power supply module, the first magnet 43 adsorbs the iron block or the second magnet to ensure the stability of the assembly of the two and improve the convenience of assembly.

[0064] Specifically, Figure 3 As shown, an indicator light 44 is provided on the main control board 3, and a light-transmitting member 50 is embedded in the main control board cover 40. The indicator light 44 is directly opposite to the light-transmitting member 50, and the light of the indicator light 44 is emitted outward through the light-transmitting member 50, so that the user can understand the working status of the charging module. For example: when the battery 1 is out of power, a red light is emitted to remind timely charging, and when it is full, a green light is emitted to indicate that the battery is fully charged. When the battery 1 is in the power-using state, a blue light is displayed, and so on. The specific situation can be set according to actual needs, and no excessive restrictions are given here.

The exceeding portion forms a mounting groove with the end of the bracket 20, and one end of the atomizer bin is inserted into the mounting groove to realize the assembly of the atomizer bin and the battery module. At this time, the end of the atomizer bin contacts the head of the spring contact terminal 9 to realize electrical connection.
