However, in the later maintenance and assembly process, due to the small installation application space of the fuse base and the influence of electrical components, wiring, etc., the installation and connection between the BMS components and the fuse base is very troublesome. Continuing to use the bolt fixing method will make the installation and removal operations between the BMS components and the fuse base take a lot of time, which can no longer meet the current application requirements.

[0049] In order to solve the above technical problems, the present embodiment provides a battery and an electrical device, which can facilitate the installation of the BMS component on the fuse base, reduce the space restrictions on the installation of the BMS component, and improve the efficiency of the assembly operation.

[0050] In addition, the battery mentioned in this embodiment refers to a physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in this application may include a battery module or a battery pack.

[0052] The battery described in the embodiments of the present application is not limited to the electrical devices described above, but can also be applied to all electrical devices using batteries. However, for the sake of simplicity, the following embodiments are described using electric vehicles as examples.

[0053] like Figures 1 to 6 As shown, a battery provided according to some embodiments of the present application includes a BMS component 1 and a fuse base 2; the BMS component 1 is provided with a first clamping portion 11; the fuse base 2 is provided with a first matching portion 21, the first clamping portion 11 and the first matching portion 21 are clamped and matched with each other, and a detachable connection is formed between the BMS component 1 and the fuse base 2.

[0054] In some embodiments, the BMS (Battery Management System) component 1 is used to manage the application performance of the battery.

[0055] In some embodiments, the fuse base 2 is installed and fixed in the battery 3.

[0056] In some embodiments, the fuse base 2 is installed and fixed in the control box 4.

[0057] By providing a first clamping portion 11 on the BMS component 1 and then providing a first matching portion 21 on the fuse base 2, the BMS component 1 can be detachably installed on the fuse base 2 through the clamping fit between the first clamping portion 11 and the first matching portion 21. By adopting the clamping installation connection method, there is no need to use fasteners such as bolts to fix the BMS component 1, thereby avoiding the trouble of bolt alignment and interference with the screwdriver operating space due to the limitation of the installation space, so that the installation efficiency of the BMS component 1 can be higher.

[0058] As an example of one of the applications, refer to Figures 1 to 3As shown, the first clamping portion 11 includes a clamping strip body 111, one end of the clamping strip body 111 is connected to the BMS component 1, and the other end is extended and can be elastically deformed relative to the BMS component 1, and a hook 112 is provided at the extended end of the clamping strip body 111; the first matching portion 21 is a clamping groove 211 provided on the fuse base 2.

[0059] In some embodiments, reference Figure 3 As shown, the clip bodies 111 are arranged in pairs and are respectively located on both sides of the BMS assembly 1; wherein, there is a gap between the inner side surface of each clip body 111 and the BMS assembly 1, so that the clip body 111 can be elastically deformed relative to the BMS assembly 1. The hook 112 is arranged on the outer side surface of the clip body 111.

[0060] In some embodiments, the number and position of the card slots 211 correspond to the card strip body 111 one by one.

[0061] In some embodiments, the slot 211 is disposed through the fuse base 2 so that the fuse base 2 can be made thinner, thereby reducing the installation space occupied.

[0062] The hook 112 is provided to facilitate engagement with the slot 211, thereby enabling the BMS assembly 1 to be installed on the fuse base 2; and the clip body 111 is provided to facilitate providing a certain elastic force, thereby making the engagement between the hook 112 and the slot 211 more stable.

[0063] As another application form, the first clamping portion 11 is a clamping slot 211 arranged on the BMS component 1; the first matching portion 21 includes a clamping strip body 111, one end of the clamping strip body 111 is connected to the fuse base 2, and the other end is extended and can be elastically deformed relative to the fuse base 2, and a hook 112 is provided at the extended end of the clamping strip body 111.

[0064] It is understandable that the slot 211 can also be set on the BMS component 1, and the hook 112 is correspondingly set on the fuse base 2. In this case, the BMS component 1 can still be installed on the fuse base 2 by the engagement between the hook 112 and the slot 211.

[0065] As an example of one of the applications, continue to refer to Figures 1 to 3As shown, the first clamping portion 11 is arranged on the side of the BMS assembly 1 , a limiting column 12 is arranged on the side of the first clamping portion 11 , and an adjustment gap is formed between the end of the limiting column 12 and the inner side of the first clamping portion 11 .

[0066] In some embodiments, the cross-sectional shape of the limiting column 12 can be set to be one of a circular shape, an elliptical shape or a polygonal shape.

[0067] In some embodiments, the limiting column 12 and the first clamping portion 11 are integrally formed on the BMS component 1 by, for example, casting.

[0068] The limiting column 12 can limit the deformation range of the first clamping part 11. At this time, the size of the adjustment gap corresponds to the deformation range of the first clamping part 11, thereby avoiding damage to the first clamping part 11 due to excessive deformation range during use.

[0069] As an example of one application, Figures 1 to 3 As shown, the slot 211 is concavely arranged toward the side of the BMS assembly 1 and is connected with the edge of the fuse base 2 to form a guide slot 212 .

[0070] The guide groove 212 can play a guiding role when the first clamping portion 11 and the first matching portion 21 are clamped together, so as to improve the clamping efficiency between the first clamping portion 11 and the first matching portion 21 .

[0071] As an example of one of the applications, continue to refer to Figures 1 to 3 As shown, the side of the fuse base 2 facing the BMS component 1 is concavely arranged to form a mounting concave surface 22 , and the BMS component 1 is arranged on the mounting concave surface 22 .

[0072] In some embodiments, the shape of the mounting concave surface 22 is adapted to the shape of the BMS component 1, so that after the BMS component 1 is installed, the outer periphery of the BMS component 1 can be at least partially supported on the inner wall surface of the mounting concave surface 22, thereby improving the fit and stability between the BMS component 1 and the fuse base 2 after installation.

[0073] By setting the mounting concave surface 22, the installation of the BMS component 1 can be facilitated, and the space in the normal direction of the mounting concave surface 22 can be utilized, so that after the BMS component 1 is installed on the fuse base 2, its overall thickness can be better controlled.

[0074] As an example of one of the applications, refer to Figure 1 , Figure 3 As shown, the BMS component 1 is provided with a second clamping portion 13, and the fuse base 2 is provided with a second matching portion 23, and the second clamping portion 13 and the second matching portion 23 are plug-fitted with each other; the second matching portion 23 is located below the first matching portion 21.

[0075] The plug-in connection between the second clamping portion 13 and the second matching portion 23 can facilitate further improving the installation stability of the BMS component 1 on the fuse base 2. During installation, the second clamping portion 13 and the second matching portion 23 can be aligned and plugged in first to pre-position the installation position of the BMS component 1, and then the first clamping portion 11 and the first matching portion 21 can be connected by a clamping connection, which is simpler and more convenient in operation.

[0076] As one application example, the second clamping portion 13 is a protrusion provided on the BMS assembly 1, and the second matching portion 23 is a slot provided on the fuse base 2;

[0077] Alternatively, the second clamping portion 13 is a slot provided on the BMS assembly 1 , and the second matching portion 23 is a protrusion provided on the fuse base 2 .

[0078] In some embodiments, Figure 2 As shown, the protrusion is arranged on the BMS component 1, and the slot is arranged on the fuse base 2; at this time, the arrangement of the limiting column 12 and the protrusion can facilitate improving the structural strength of the BMS component 1.

[0079] It is understandable that the slot may be disposed on the BMS component 1 , and the protrusion may be disposed on the fuse base 2 .

[0080] By plugging the protrusion into the slot, the BMS component 1 can be pre-installed on the fuse base 2, making installation and positioning more convenient.

[0081] As an example of one application, Figures 1 to 5 As shown, the fuse base 2 includes a base body 24, and fixed connection parts 25 arranged on both sides of the bottom of the base body 24, and the fixed connection parts 25 are provided with mounting holes 251;

[0082] A reserved space for installing the fuse 5 is formed between the fixed connection parts 25 on both sides.

[0083] In some embodiments, the fuse base 2 is formed as an integral structure.

[0084] By providing the mounting hole 251, it is possible to facilitate the installation and fixation of the fuse base 2 on the external component; and the provided reserved space can facilitate the installation and setting of the fuse 5, making the installation layout more compact.

[0085] On the other hand, reference Figure 6 As shown, in this embodiment, there is provided an electric device 6, in which the battery 3 as described above is arranged.

[0086] By applying the battery 3 as described above in the electrical device 6, when the BMS component 1 of the battery 3 needs to be maintained, the disassembly and reinstallation operations between the BMS component 1 and the fuse base 2 can be simpler and more convenient, thereby improving the operating efficiency of the operator.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
