[0046] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0047] The present invention provides a battery 1000, such as Figures 1 to 6 As shown, the battery 1000 includes a control board 20, a battery cell 30 and a housing 10; wherein the battery cell 30 is mounted on the control board 20 in a first direction (such as Figure 3 On one side (as shown in the X direction in FIG), the battery cell 30 is electrically connected to the control board 20; the housing 10 is disposed on the side of the control board 20 facing away from the battery cell 30. The battery 1000 of the present application can solve the problem of the control board 20 being easily damaged, thereby improving the protection of the control board 20 and effectively enhancing the durability of the battery 1000.

[0048] Specifically, the battery 1000 is equipped with a shell 10, the battery cell 30 is located on one side of the control board 20, and the shell 10 is blocked on the other side of the control board 20. Compared with the embodiment that only relies on the adhesive film 60 to encapsulate the battery cell 30 and the control board 20, the shell 10 can provide an additional external protection layer for the control board 20 to effectively prevent external objects from directly contacting the control board 20, thereby reducing the possibility of damage to the control board 20. It can be seen that the battery 1000 has better durability.

[0049] The shape of the housing 10 of the present application can also be adjusted according to the size of the control board 20 and the battery cell 30, and is not limited to this. Furthermore, the housing 10 can be made of a variety of materials, which are not limited to this. For example, it can be made of plastic to protect the control board 20 while reducing its own weight, making the battery 1000 easier to carry and replace.

[0050] In the present application, the control board 20 may be a protection circuit board, which is mainly used to monitor and manage various parameters of the battery 1000 to ensure that the battery 1000 works more safely and efficiently. For example, it can prevent short circuits.

[0051] In the above solution, there are many ways to connect the housing 10 and the control board 20, which can be bonding, threaded connection, clamping, etc. For example, in this application, the housing 10 and the control board 20 are assembled by clamping. Specifically,

[0052] Reference Figure 7 and Figure 8 The housing 10 has a receiving groove 11 on the side facing the battery cell 30. The control board 20 is received in the receiving groove 11. A snap-fit ​​block 111 is provided on the wall of the receiving groove 11. The control board 20 is sandwiched between the bottom of the receiving groove 11 and the snap-fit ​​block 111. With this arrangement, on the one hand, the control board 20 is completely received in the receiving groove 11, and the housing 10 can fully protect it as a whole, thus providing better protection. On the other hand, the control board 20 is limited and installed in the receiving groove 11 by the snap-fit ​​block 111, which can improve the connection stability between the control board 20 and the housing 10 and make the connection between the two more secure. More specifically, the shape of the receiving groove 11 is adapted to the size of the control board 20, so that the side groove walls of the receiving groove 11 can more effectively limit the movement of the control board 20 while facilitating positioning and installation. Preferably, the clamping block 111 has a guiding surface, which is arranged toward the notch of the accommodating groove 11 . The guiding surface can guide the control board 20 to be placed between the bottom of the accommodating groove 11 and the clamping block 111 , thereby improving assembly efficiency.

[0053] In addition, a plurality of ridges are provided at the bottom of the accommodating groove 11, and the ridges are arranged at intervals to form an avoidance space. The control board 20 is clamped between the ridges and the clamping block 111. The avoidance space can not only avoid the electronic components on the control board 20 but also facilitate its heat dissipation, so that the battery 1000 can work stably.

[0054] In the present application, there are also many ways to connect the shell 10 and the battery cell 30, which can be bonding, threaded connection, clamping, etc., which are not limited here. Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 For example, the battery 1000 further includes an adhesive film 60 that wraps around the outer sides of the housing 10 and the battery cell 30 to limit the position of the battery cell 30 on the housing 10. Specifically, the adhesive film 60 can be an EVA film that can be semi-enclosed or fully enclosed to wrap around the entire outer circumference formed by the battery cell 30 and the housing 10, thereby maintaining a tight fit between the two.

[0055] And, in order to further improve the connection stability between the two. Figure 3 and Figure 9 In one embodiment, the housing 10 includes an end surface 12, and the receiving groove 11 is provided on the end surface 12. The shape of the end surface 12 is adapted to the outer contour of the battery cell 30, and the battery cell 30 abuts against the end surface 12. This arrangement increases the contact area between the end surface 12 and the battery cell 30, allowing them to maintain a close fit and improving connection stability.

[0056] Reference Figure 6 and Figure 9In another embodiment, the battery cell 30 is at least partially accommodated in the accommodating groove 11. The battery 1000 further includes a contoured pad 40 installed in the accommodating groove 11 and located between the control board 20 and the battery cell 30. The shape of the side of the contoured pad 40 facing the battery cell 30 is adapted to the outer contour of the battery cell 30, and the battery cell 30 abuts against the contoured pad 40. This arrangement supports and positions the battery cell 30, facilitating installation. Furthermore, the shape of the side of the contoured pad 40 facing the battery cell 30 is adapted to the outer contour of the battery cell 30, which also increases the contact area between the contoured pad 40 and the battery cell 30, thereby improving the connection stability between the two.

[0057] Refer again Figure 9 Preferably, the contour pad 40 and the control board 20 are sandwiched between the clamping block 111 and the bottom of the receiving groove 11, thereby achieving the installation and fixation of the contour pad 40 while simplifying the structure of the housing 10. Preferably, the control board 20 can be mounted on the contour pad 40. In this arrangement, during installation, the control board 20 and the contour pad 40 can be placed together between the clamping block 111 and the bottom of the receiving groove 11, which improves assembly efficiency.

[0058] Further, refer to Figure 5 and Figure 6 In this embodiment, the battery cell 30 includes a second direction (such as Figure 3 The housing 10 is provided with two lugs 13, each located on one side of the positive electrode 31 and the negative electrode 32 facing each other (as shown in the Y direction in FIG). The housing 10 is provided with two lugs 13, each located on the side opposite the positive electrode 31 and the negative electrode 32, with the second direction being perpendicular to the first direction. In this manner, the lugs 13 protect the positive electrode 31 and the negative electrode 32 of the battery cell 30 from direct contact with the outside world, thereby enhancing the protection provided by the housing 10 to the battery cell 30. Furthermore, since both the positive electrode 31 and the negative electrode 32 are electrically connected to the control board 20, the provision of the lugs 13 can also prevent poor connection and power failure caused by external contact.

[0059] Reference Figure 2 and Figure 5 In one embodiment, the battery 1000 further includes a backing plate 50, which is mounted on the lug 13 and disposed opposite the positive electrode 31; and / or, the backing plate 50 is mounted on the lug 13 and disposed opposite the negative electrode 32. In this manner, the backing plate 50 can further protect the positive electrode 31 and the negative electrode 32 of the battery cell 30.

[0060] Specifically, the control board 20 includes two metal contact sheets 23, which are in contact with the positive electrode 31 and the negative electrode 32 respectively and are conductive. The pad 50 can be installed on the side of the lug facing the metal contact sheet 23 and the positive electrode 31 or the metal contact sheet 23 and the negative electrode 32, or the pad 50 can be installed on the side of the lug facing away from the metal contact sheet 23 and the positive electrode 31 or the metal contact sheet 23 and the negative electrode 32.

[0061] Preferably, the pad 50 may be an EVA board, which has certain elasticity and buffering properties and can provide a shock-absorbing effect when the battery 1000 accidentally falls, thereby improving the reliability of the battery 1000 .

[0062] Reference Figure 3 、 Figure 6 、 Figure 10 as well as Figure 11 In one embodiment, a through hole 112 is provided at the bottom of the accommodating groove 11, and the control board 20 is provided with a connector 21. The connector 21 is passed through the through hole 112 and is at least partially exposed outside the battery 1000. After the control board 20 is placed in the accommodating groove 11, the connector 21 can be aligned with the through hole 112, and then its connecting part will naturally be exposed outside the battery 1000, which is convenient for connection with external equipment. There is no need for complicated installation steps, which is more convenient and efficient. It can be seen that the advantage of such a design is that it can effectively improve the assembly efficiency of the battery 1000. Specifically, the connector 21 can be a knife connector or a plug connector, which is at least partially exposed outside the through hole 112, which is convenient for plugging in and out, and the through hole 112 can also limit another part of it to prevent the connector 21 from moving when plugging in.

[0063] In addition, in order to increase the connection distance between the battery 1000 and the external device, the connector 21 is usually further configured with a wire 22 to extend the connection distance, so that the housing 10 can adapt to such a connector 21. Figure 12 The housing 10 includes sidewalls extending in the first direction. A through-slot 113 extends through the bottom of the accommodating groove 11. One side of the through-slot 113 extends through the sidewall, while the other side extends in the first direction and through the wall of the through-hole 112. The through-slot 113 serves as a routing channel for the wire 22. When the control board 20 is placed in the accommodating groove 11, the wire 22 can be aligned with the connector 21 and the through-hole 112 through the routing channel, enabling quick assembly of the two. This arrangement also has the advantage of reducing bending of the wire 22 during installation, thereby reducing damage to the wire 22.

[0064] Reference Figure 2 and Figure 5 In one embodiment, the battery 1000 further includes a pull tab 70, which is exposed on the outside of the battery 1000 and connected to the adhesive film 60 or the housing 10. This design allows the adhesive film 60 to be separated from the housing 10 and the battery 1000 by pulling the pull tab 70, thereby facilitating direct removal and replacement of the battery 1000 and improving efficiency.

[0065] Specifically, the adhesive film 60 is wrapped around the outer peripheral surface formed by the shell 10 and the battery 1000 along the second direction, and then a force is applied to the pull tape 70 in the second direction so that the battery 1000 and the shell 10 can be directly pulled out of the adhesive film 60 along the second direction to achieve separation, thereby facilitating the removal of the battery 1000.

[0066] Reference Figure 11 and Figure 12 In a more specific embodiment, the drawstring 70 is connected to the shell 10, and an opening 14 is penetrated through the wall of the accommodating groove 11 in the shell 10. One end of the drawstring 70 is fixed in the accommodating groove 11, and the other end passes through the opening 14 for the user to pull.

[0067] Refer again Figure 2 In another more specific embodiment, the pull tape 70 is connected to the adhesive film 60 by bonding, and the pull tape 70 is bonded to the side of the adhesive film 60 facing away from the battery 1000 and the shell 10 .

[0068] Reference Figure 5 and Figure 2 In one embodiment, the battery 1000 further includes a fixing strap 80. The fixing strap 80 is mounted on both ends of the assembled housing 10 and battery 1000 in the second direction, thereby improving the connection and fit between the adhesive film 60 and the housing 10 and the battery 1000. Specifically, the fixing strap 80 may be an EVA strap, which improves the connection stability and provides a shock-absorbing effect.
