[0003] This application relates to the field of power battery technology, specifically to a battery and an electrical device. Background Technology

[0004] Currently, in the application of power batteries, a Battery Management System (BMS) is installed to facilitate the management of the battery's performance during use. In existing practices, the BMS component is usually mounted on the fuse base using fasteners such as bolts. However, the installation space on the fuse base is very limited, and the arrangement of electrical components and wiring makes the installation and removal of the BMS component cumbersome, requiring a significant amount of time for assembly and maintenance. Summary of the Invention

[0005] In view of the above problems, this application provides a battery and power supply device that can facilitate the installation of BMS components on fuse bases and improve assembly efficiency.

[0006] The technical means adopted in this application to solve the above-mentioned technical problems are:

[0007] In one aspect, the embodiments of this application provide a battery, including:

[0008] BMS component, wherein a first snap-fit ​​portion is provided on the BMS component;

[0009] A fuse base is provided with a first mating part, and a first snap-fit ​​part is snap-fitted with the first mating part to form a detachable connection between the BMS component and the fuse base.

[0010] In this application, a first snap-fit ​​portion is provided on the BMS component, and a first mating portion is provided on the fuse base. The snap-fit ​​between the first snap-fit ​​portion and the first mating portion enables the BMS component to be detachably installed on the fuse base. Furthermore, the snap-fit ​​method eliminates the need for bolts or other fasteners, resulting in higher installation efficiency.

[0011] In some embodiments, the first latching portion includes a latch body, one end of which is connected to the BMS component, and the other end is extended and can elastically deform relative to the BMS component. The extended end of the latch body is provided with a latch hook.

[0012] The first mating part is a slot provided on the fuse base.

[0013] In this application, the hook can be easily engaged with the slot to enable the installation of the BMS component on the fuse base; and the clip body can provide a certain elastic force to make the engagement between the hook and the slot more stable.

[0014] In some embodiments, the first latching portion is a card slot disposed on the BMS component;

[0015] The first mating part includes a locking strip body, one end of which is connected to the fuse base, and the other end is extended and can elastically deform relative to the fuse base. The extended end of the locking strip body is provided with a locking hook.

[0016] In this application, the slot can also be set on the BMS component, and the hook is correspondingly set on the fuse base. In this case, the BMS component can still be installed on the fuse base through the snap-fit ​​between the hook and the slot.

[0017] In some embodiments, the first latching portion is disposed on the side of the BMS component, and a limiting post is provided on the side of the first latching portion, with an adjustment gap formed between the end of the limiting post and the inner side of the first latching portion.

[0018] In this application, the limiting post can limit the first snap-fit ​​part to reduce the risk of damage caused by excessive deformation of the first snap-fit ​​part during use.

[0019] In some embodiments, the slot is recessed toward the side of the BMS component and communicates with the edge of the fuse base to form a guide groove.

[0020] In this application, the guide groove allows the first snap-fit ​​portion to engage with the first mating portion.

[0021] The first engaging part acts as a guide during the snap-fit ​​process, thereby improving the snap-fit ​​efficiency between the first engaging part and the first mating part.

[0022] In some embodiments, the fuse base is recessed on the side facing the BMS assembly to form a mounting recess, and the BMS assembly is disposed on the mounting recess.

[0023] In this application, the mounting concave surface facilitates the installation of the BMS component and also allows for the utilization of the space in the normal direction of the mounting concave surface.

[0024] In some embodiments, the BMS component is provided with a second snap-fit ​​portion, and the fuse base is provided with a second mating portion, wherein the second snap-fit ​​portion and the second mating portion are inserted into each other; the second mating portion is located below the first mating portion.

[0025] In this application, the insertion connection between the second snap-fit ​​part and the second mating part allows for convenient...

[0026] This further improves the installation stability of the BMS component on the fuse base.

[0027] In some embodiments, the second snap-fit ​​portion is a protrusion provided on the BMS component, and the second mating portion is a slot provided on the fuse base;

[0028] Alternatively, the second snap-fit ​​portion is a slot provided on the BMS assembly, and the second mating portion is a protrusion provided on the fuse base.

[0029] In this application, the insertion between the protrusion and the slot facilitates the pre-installation of the BMS component on the fuse base, making installation and positioning more convenient.

[0030] In some embodiments, the fuse base includes a base body and fixed connection portions disposed on both sides of the bottom of the base body, wherein the fixed connection portions are provided with mounting holes;

[0031] A reserved space for installing a fuse is formed between the fixed connection parts on both sides.

[0032] In this application, the mounting holes facilitate the installation and fixing of the fuse base on external components; while the reserved space facilitates the installation of the fuse, resulting in a more compact installation layout.

[0033] On the other hand, the embodiments of this application provide an electrical device in which a battery as described above is disposed.

[0034] Other features and advantages of this application will be set forth in the following description, or some features and advantages may be inferred from the content of the description or determined without doubt, or may be learned by implementing the above embodiments of this application.

[0054] Currently, the BMS (Battery Management System) components in batteries are usually installed on fuse bases. However, during later maintenance and assembly, the limited space for installing the fuse base, as well as the influence of electrical components and wiring, makes the installation and connection between the BMS components and the fuse base very troublesome. Continuing to use bolt fixing would require a lot of time for the installation and removal of the BMS components from the fuse base, which can no longer meet current application requirements.

[0055] To address the aforementioned technical problems, this embodiment provides a battery and power supply device that facilitates the installation of BMS components on fuse bases, reduces space constraints on BMS component installation, and improves assembly efficiency.

[0056] Furthermore, the battery mentioned in this embodiment refers to a battery comprising one or more individual battery cells to provide higher voltage and

[0057] A physical module with a capacity. For example, the battery mentioned in this application may include a battery module or a battery pack, etc.

[0058] It is understood that the electrical devices to which the batteries described in the embodiments of this application are applicable can take many forms, such as mobile phones, portable devices, laptops, electric vehicles, electric cars, ships, spacecraft, electric toys, and power tools, etc. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft, etc. Electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers.

[0059] The batteries described in the embodiments of this application are not limited to the electrical devices described above, but can also be applied to all electrical devices that use batteries. However, for the sake of brevity, the following embodiments are all illustrated using electric vehicles as examples.

[0060] As shown in Figures 1 to 6, a battery according to some embodiments of this application includes a BMS component 1 and a fuse base 2; the BMS component 1 is provided with a first snap-fit ​​portion 11; the fuse base 2 is provided with a first mating portion 21, the first snap-fit ​​portion 11 and the first mating portion 21 are snap-fitted together to form a detachable connection between the BMS component 1 and the fuse base 2.

[0061] In some embodiments, the BMS (Battery Management System) component 1 is used to manage the application performance of the battery.

[0062] In some embodiments, the fuse base 2 is mounted and fixed inside the battery 3.

[0063] In some embodiments, the fuse base 2 is installed and fixed inside the control box 4.

[0064] By providing a first snap-fit ​​part 11 on the BMS component 1 and a first mating part 21 on the fuse base 2, the BMS component 1 can be detachably installed on the fuse base 2 through the snap-fit ​​engagement between the first snap-fit ​​part 11 and the first mating part 21. This snap-fit ​​installation method eliminates the need for bolts or other fasteners to fix the BMS component 1, reducing the risk of bolt alignment difficulties and screwdriver interference due to limited installation space, thus improving the installation efficiency of the BMS component 1.

[0065] As one application example, referring to Figures 1 to 3, the first latching part 11 includes a latching strip body 111. One end of the latching strip body 111 is connected to the BMS component 1, and the other end is extended and can elastically deform relative to the BMS component 1. The extended end of the latching strip body 111 is provided with a latching hook 112. The first mating part 21 is a latching groove 211 provided on the fuse base 2.

[0066] In some embodiments, referring to FIG3, the card strip bodies 111 are arranged in pairs and respectively located on both sides of the BMS component 1; wherein, there is a gap between the inner side surface of each card strip body 111 and the BMS component 1, so that the card strip body 111 can elastically deform relative to the BMS component 1. The card hook 112 is disposed on the outer side surface of the card strip body 111.

[0067] In some embodiments, the number and position of the card slots 211 correspond one-to-one with the card strip body 111.

[0068] In some embodiments, the slot 211 is provided through the fuse base 2 so that the fuse base 2 can be made thinner, thereby reducing the space occupied for installation.

[0069] The hook 112 facilitates engagement with the slot 211, enabling the installation of the BMS component 1 on the fuse base 2. The clip body 111 provides elastic force, ensuring a more stable engagement between the hook 112 and the slot 211.

[0070] As another application form, the first snap-fit ​​part 11 is a slot 211 provided on the BMS component 1; the first mating part 21 includes a snap-fit ​​body 111, one end of the snap-fit ​​body 111 is connected to the fuse base 2, the other end is extended and can be elastically deformed relative to the fuse base 2, and a snap hook 112 is provided at the extended end of the snap-fit ​​body 111.

[0071] It is understood 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 snap-fit ​​between the hook 112 and the slot 211.

[0072] As one application example, continuing to refer to Figures 1 to 3, the first snap-fit ​​portion 11 is disposed on the side of the BMS component 1, and a limiting post 12 is disposed on the side of the first snap-fit ​​portion 11, and an adjustment gap is formed between the end of the limiting post 12 and the inner side of the first snap-fit ​​portion 11.

[0073] In some embodiments, the cross-sectional shape of the limiting post 12 can be set to one of a circle, an ellipse, or a polygon.

[0074] In some embodiments, the limiting post 12 and the first snap-fit ​​part 11 are integrally formed on the BMS component 1, such as by casting.

[0075] By setting the limiting post 12, the deformation range of the first locking part 11 can be limited. At this time, the size of the adjustment gap corresponds to the deformation range of the first locking part 11, thereby reducing the risk of damage caused by excessive deformation of the first locking part 11 during use.

[0076] As one application example, as shown in Figures 1 to 3, the slot 211 is recessed on the side facing the BMS component 1 and communicates with the edge of the fuse base 2 to form a guide groove 212.

[0077] The guide groove 212 can guide the engagement of the first snap-fit ​​part 11 and the first mating part 21, thereby improving the engagement efficiency between the first snap-fit ​​part 11 and the first mating part 21.

[0078] As one application example, continuing to refer to Figures 1 to 3, the fuse base 2 is recessed on the side facing the BMS component 1 to form a mounting recess 22, and the BMS component 1 is disposed on the mounting recess 22.

[0079] In some embodiments, the shape of the mounting recess 22 is adapted to the shape of the BMS component 1, so that after installation, the outer periphery of the BMS component 1 can at least partially rest on the inner wall surface of the mounting recess 22, thereby improving the fit and stability between the BMS component 1 and the fuse base 2 after installation.

[0080] The mounting recess 22 facilitates the installation of the BMS component 1 and allows for better utilization of the space in the normal direction of the mounting recess 22, so that the overall thickness of the BMS component 1 can be better controlled after it is installed on the fuse base 2.

[0081] As one application example, referring to Figures 1 and 3, the BMS component 1 is provided with a second snap-fit ​​part 13, and the fuse base 2 is provided with a second mating part 23. The second snap-fit ​​part 13 and the second mating part 23 are inserted and mated together; the second mating part 23 is located below the first mating part 21.

[0082] The insertion connection between the second snap-fit ​​part 13 and the second mating part 23 facilitates further improvement in the installation stability of the BMS component 1 on the fuse base 2. During installation, the second snap-fit ​​part 13 and the second mating part 23 can be aligned and inserted first to pre-position the installation position of the BMS component 1, and then the snap-fit ​​connection between the first snap-fit ​​part 11 and the first mating part 21 can be achieved, making the operation simpler and more convenient.

[0083] As one application example, the second snap-fit ​​part 13 is a protrusion provided on the BMS component 1, and the second mating part 23 is a slot provided on the fuse base 2;

[0084] Alternatively, the second snap-fit ​​portion 13 may be a slot provided on the BMS component 1, and the second mating portion 23 may be a protrusion provided on the fuse base 2.

[0085] In some embodiments, as shown in FIG2, the protrusion is disposed on the BMS component 1, and the slot is disposed on the fuse base 2; in this case, the provision of the limiting post 12 and the protrusion can facilitate the improvement of the structural strength of the BMS component 1.

[0086] It is understood that the slot can also be located on the BMS component 1, and the protrusion can be located on the fuse base 2.

[0087] The insertion between the protrusion and the slot facilitates the pre-installation of the BMS component 1 on the fuse base 2, making installation and positioning more convenient.

[0088] As one application example, as shown in Figures 1 to 5, the fuse base 2 includes a base body 24 and fixed connection parts 25 disposed on both sides of the bottom of the base body 24. The fixed connection parts 25 are provided with mounting holes 251.

[0089] A reserved space for installing a fuse 5 is formed between the fixed connection parts 25 on both sides.

[0090] In some embodiments, the fuse base 2 is formed as a single piece.

[0091] The mounting hole 251 facilitates the installation and fixation of the fuse base 2 on the external component; while the reserved space facilitates the installation of the fuse 5, making the installation layout more compact.

[0092] On the other hand, referring to FIG6, this embodiment provides an electrical device 6, which is provided with a battery 3 as described above.

[0093] By applying the battery 3 as described above in the electrical device 6, the disassembly and reinstallation of the BMS component 1 and the fuse base 2 can be made simpler and more convenient when maintenance operations are required on the BMS component 1 of the battery 3, thereby improving the work efficiency of the operator.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
