Description

Technical Field

[0001] This disclosure relates to the field of battery design technology, and in particular to a fuse mounting component, a fuse assembly, and a battery pack. Background Technology

[0002] Fuses are an important component of battery packs, used to cut off current in the event of overload or short circuit, ensuring electrical safety. Fuses are secured inside the battery pack housing using fuse mounting hardware and bolts.

[0003] Currently, fuse mounting components can be divided into two types. The first type includes a metal mounting component and an insulating post. The metal mounting component consists of a connected base and a frame. The base is connected to the battery pack housing by bolts, one end of the insulating post is connected to the base, and the fuse is connected to the other end of the insulating post by bolts. The second type is a one-piece molded insulating mounting component, consisting of an insulating base and an insulating frame. The insulating base is connected to the battery pack housing by bolts, and the fuse is connected to the insulating frame by bolts.

[0004] However, for the first type of fuse mount, the assembly process requires separate installation of the metal mounting piece and the insulating post, which is cumbersome. For the second type of insulating mount, in order to ensure sufficient electrical clearance between the bolt and the fuse, and to ensure sufficient strength of the insulating mount, there must be a sufficient distance between the wall of the insulating base near the fuse and the fuse, and the insulating base needs to have sufficient thickness. This makes the overall size of the insulating mount larger, resulting in a larger space occupied within the battery pack. Utility Model Content

[0005] This disclosure provides a fuse mounting component, a fuse assembly, and a battery pack, which can solve the technical problems existing in related technologies. The technical solutions of the fuse mounting component, fuse assembly, and battery pack are as follows:

[0006] In a first aspect, this disclosure provides a fuse mounting component, which includes a connected base and a frame.

[0007] The base has a first wall, a second wall, and a receiving hole. The first wall and the second wall are arranged opposite to each other. The first wall is used to be in contact with the housing of the battery pack. The receiving hole connects the first wall and the second wall. The receiving hole has an abutment structure, which is used to abut against a bolt head. The bolt head is the head of the bolt that connects the base to the housing.

[0008] The frame is located on the second wall and is used to connect to the fuse.

[0009] In one possible implementation, the receiving hole is a stepped hole, and the stepped surface of the stepped hole is the abutment structure.

[0010] In one possible implementation, the frame includes a receiving portion, a first connecting portion, and a second connecting portion;

[0011] The receiving part is connected to the base body, and the receiving part has a receiving cavity for accommodating the tube body of the fuse;

[0012] The first connecting portion and the second connecting portion are distributed at both ends of the receiving portion and are respectively connected to the receiving portion. The first connecting portion is used to connect to the first terminal of the fuse, and the second connecting portion is used to connect to the second terminal of the fuse.

[0013] In one possible implementation, the first connecting portion has a first fixing portion, which is used to provide mounting space for the first fixing member, and the first fixing member is used to connect the first connecting portion and the first terminal.

[0014] The second connecting portion has a second fixing portion, which provides mounting space for the second fixing member, and the second fixing member is used to connect the second connecting portion and the second terminal.

[0015] In one possible implementation, the fuse mounting component further includes a first reinforcing component located on the side of the receiving portion opposite to the receiving cavity, and connected to the base and the receiving portion respectively.

[0016] In one possible implementation, the first reinforcing component includes a plurality of first reinforcing ribs, which are spaced apart along a first direction, the first direction being the direction from the first connecting portion to the second connecting portion.

[0017] In one possible implementation, the first connecting portion and the second connecting portion are respectively connected to the base body.

[0018] In one possible implementation, the fuse mounting component further includes a second reinforcing assembly, which includes a second reinforcing rib and a third reinforcing rib;

[0019] The second reinforcing rib is connected to the receiving portion and the first connecting portion, respectively;

[0020] The third reinforcing rib is connected to the receiving part and the second connecting part, respectively.

[0021] In one possible implementation, the seat has a clearance groove located on the second wall surface and arranged opposite to the receiving cavity.

[0022] In one possible implementation, the base and the frame are integrally formed.

[0023] In a second aspect, this disclosure provides a fuse assembly including the fuse mounting element as described in the first aspect and its possible implementations.

[0024] In one possible implementation, the fuse includes a connected tube, a first terminal, and a second terminal, the first terminal and the second terminal being respectively connected to the frame;

[0025] There is a gap between the tube and the frame, which provides space for heat dissipation of the tube.

[0026] Thirdly, this disclosure provides a battery pack that includes the fuse assembly from the second aspect and its possible implementations.

[0027] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0028] This disclosure provides a fuse mounting component. In this component, the base and frame are connected without additional assembly, making the entire fuse installation process more convenient. Furthermore, the base abuts against the head of the first bolt through an abutment structure within a receiving hole, thus connecting the fuse mounting component to the battery pack housing. Compared to related technologies where the bolt head directly abuts against the wall of the base away from the housing, the change in the position of the second wall does not alter the electrical clearance between the fuse and the first bolt. Therefore, while maintaining the same thickness of the base, the gap between the second wall and the fuse can be reduced, thereby decreasing the overall size of the fuse connector while meeting strength requirements.

[0029] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0062] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0063] The terminology used in the embodiments section of this disclosure is for illustrative purposes only and is not intended to limit the disclosure. Unless otherwise defined, the technical or scientific terms used herein should be understood in their ordinary sense by one of ordinary skill in the art to which this disclosure pertains.

The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0064] This disclosure provides a fuse mounting component that is simple to assemble, meets strength requirements, and is small in size. For example... Figure 1 As shown, the fuse mounting component 100 includes a connected base 1 and a frame 2.

[0065] The base 1 is a component in the fuse mounting assembly 100 used to connect to the battery pack housing, see [link / reference]. Figure 8 The battery pack housing has several bolt mounting seats on its inner wall, each with a corresponding threaded hole. The seat 1 can have a plate-like structure, and has a first wall surface 11 and a second wall surface 12 arranged opposite to each other, as well as a receiving hole 13 connecting the first wall surface 11 and the second wall surface 12. See [reference needed] Figure 1 and Figure 8 The first wall surface 11 is arranged to fit against the bolt mounting seat inside the housing so that the receiving hole 13 is arranged opposite to the threaded hole, providing installation space for the first bolt (for ease of distinction, the bolt connecting the seat 1 and the housing of the battery pack is referred to as the first bolt).

[0066] Among them, frame 2 is a component in fuse mounting assembly 100 used for connecting to fuse 200, such as... Figure 1 As shown, the frame 2 is located on the second wall 12 of the base 1 and extends in a direction away from the housing of the battery pack. The frame 2 is connected to the fuse 200 so that there is sufficient electrical clearance between the fuse 200 and the housing of the battery pack and the first bolt.

[0067] Among them, such as Figure 2 As shown, the receiving hole 13 has an abutment structure 131 inside, which abuts against the bolt head of the first bolt. In implementation, the first bolt extends into the interior of the seat 1 through the opening of the receiving hole 13 on the first wall surface 11, then extends out of the seat 1 through the opening of the receiving hole 13 on the second wall surface 12, and is screwed into the threaded hole of the bolt mounting seat. As the first bolt gradually rotates, the bolt head of the first bolt gradually approaches the abutment structure 131 and abuts against it, thereby securing the seat 1 to the battery pack housing.

[0068] Using the technical solution provided in the embodiments of this disclosure, in the fuse mounting component 100, on the one hand, the base 1 and the frame 2 are connected, and the two do not need to be assembled separately, making the entire installation process of the fuse more convenient.

[0069] On the other hand, the base 1 abuts against the bolt head of the first bolt through the abutment structure 131 provided inside the receiving hole 13, thereby achieving the connection between the fuse mounting part 100 and the battery pack housing. Compared with the related technology where the bolt head directly abuts against the wall of the base away from the housing, the change in the position of the second wall 12 does not change the electrical clearance between the fuse 200 and the first bolt. Therefore, while keeping the base 1 at the same thickness, the gap between the second wall 12 and the fuse 200 can be reduced, thereby reducing the overall size of the fuse mounting part 100 while meeting the strength requirements.

[0070] It is readily understood that the fuse mounting component 100 is made of an insulating material, which, exemplarily, may be PA66+25GF (an engineering plastic material composed of polyamide 66 and 25% glass fiber). The manufacturing process of the fuse mounting component 100 may be injection molding, and this disclosure does not limit this process.

[0071] In some examples, the base 1 and the frame 2 can be integrally molded components. For example, the base 1 and the frame 2 can be integrally molded by injection molding.

[0072] For example, see Figure 1 The number of receiving holes 13 can be multiple. The specific number of receiving holes 13 and the relative positions between multiple receiving holes 13 can be set by technicians according to actual needs or the specific structure of the battery pack housing. This disclosure does not limit this.

[0073] In some possible embodiments, the abutment structure 131 is the stepped surface of a stepped hole.

[0074] like Figure 2 As shown, the receiving hole 13 is a stepped hole. Specifically, the receiving hole 13 includes a first hole segment and a second hole segment that are connected. The first hole segment and the second hole segment are both circular holes and are arranged coaxially. The first hole segment is connected to the first wall surface 11, and the second hole segment is connected to the second wall surface 12. A stepped surface is formed between the first hole segment and the second hole segment. This stepped surface is the aforementioned abutment structure 131.

[0075] In practice, the diameter of the second hole is larger than the outer diameter of the bolt head of the first bolt, while the diameter of the first hole is smaller than the outer diameter of the bolt head of the first bolt, but larger than the outer diameter of the bolt post of the first bolt.

[0076] In some possible embodiments, the abutment structure 131 may be a protrusion structure.

[0077] like Figure 9 ( Figure 9As shown in the partial cross-sectional view of the base 1, the receiving hole 13 is a through hole, and the inner wall of the receiving hole 13 has multiple protrusions. The multiple protrusions are distributed circumferentially around the axis of the receiving hole 13, and the multiple protrusions are close to the wall surface of the second wall 12 and are coplanar.

[0078] In practice, multiple protruding structures near the second wall surface 12 abut against the bolt head of the first bolt.

[0079] In some possible embodiments, the frame 2 includes multiple connected parts.

[0080] like Figure 3 As shown, the frame 2 includes a receiving portion 21, a first connecting portion 22, and a second connecting portion 23. The first connecting portion 22 and the second connecting portion 23 are located at both ends of the receiving portion 21 and are respectively connected to the receiving portion 21. The receiving portion 21 is located on the second wall surface 12 of the base 1 and is connected to the base 1.

[0081] See Figure 3 and Figure 4 The receiving portion 21 has a receiving cavity 210, the shape of which is adapted to the shape of the outer wall of the fuse 200. Specifically, as Figure 3 As shown, the fuse 200 includes a tube body 201, a first terminal 202, and a second terminal 203. The tube body 201 has a cylindrical structure. The first terminal 202 is located inside the tube body 201 and at least partially extends out of the top surface of the tube body 201. The second terminal 203 is located inside the tube body 201 and at least partially extends out of the bottom surface of the tube body 201.

[0082] In some examples, such as Figure 2 As shown, the receiving part 21 includes a first plate 211, a second plate 212 and a connecting plate 213. The first plate 211 and the second plate 212 are both flat plates and are arranged in parallel. The distance between the first plate 211 and the second plate 212 is greater than the axial length of the tube 201. The connecting plate 213 is located between the first plate 211 and the second plate 212 and is connected to the first plate 211, the second plate 212 and the seat 1 respectively.

[0083] Furthermore, the connecting plate 213 includes a first part 2131 and a second part 2132. The first part 2131 is connected to the first plate body 211, the second plate body 212, and the base body 1, respectively. The first part 2131 is an arc-shaped plate with a radius of curvature greater than that of the outer peripheral wall of the tube body 201. The second part 2132 is a flat plate located on the side of the first part 2131 away from the base body 1, and is connected to the first part 2131, the first plate body 211, and the second plate body 212, respectively.

[0084] In practice, the first plate 211, the second plate 212 and the connecting plate 213 form a receiving cavity 210, which receives a portion of the tube 201.

[0085] In one example, the first connecting part 22 and the second connecting part 23 are respectively connected to the base 1.

[0086] like Figure 4 As shown, the first connecting portion 22 includes a first mounting plate 221 and a first block 222. The first mounting plate 221 is located on the side of the receiving portion 21 away from the second connecting portion 23, and is connected to both the receiving portion 21 and the base 1. The first block 222 is connected to both the first mounting plate 221 and the receiving portion 21. In this way, the first connecting portion 22 is not connected to the receiving portion 21 alone, which can improve the connection strength of the first connecting portion 22.

[0087] like Figure 4 As shown, the second connecting portion 23 includes a second mounting plate 231 and a second block 232. The second mounting plate 231 is located on the side of the receiving portion 21 away from the first connecting portion 22 and is connected to both the receiving portion 21 and the base 1. The second block 232 is connected to both the second mounting plate 231 and the receiving portion 21. In this way, the second connecting portion 23 is not connected to the receiving portion 21 alone, which can improve the connection strength of the second connecting portion 23.

[0088] Furthermore, such as Figure 4 As shown, the first connecting portion 22 has a first fixing portion 220, which provides mounting space for the first fixing member. The first fixing member is used to connect the first connecting portion 22 and the first terminal 202. The second connecting portion 23 has a second fixing portion 230, which provides mounting space for the second fixing member. The second fixing member is used to connect the second connecting portion 23 and the second terminal 203.

[0089] In implementation, the first fixing member is connected to the first terminal 202 and installed within the first fixing portion 220 to achieve the connection between the first terminal 202 and the first connecting portion 22. Correspondingly, the second fixing member is connected to the second terminal 203 and installed within the second fixing portion 230 to achieve the connection between the second terminal 203 and the second connecting portion 230.

[0090] In one example, both the first fixing part 220 and the second fixing part 230 are threaded holes, and both the first fixing member and the second fixing member are bolts. See also Figure 4The first fixing part 220 penetrates the first mounting plate 221 and extends into the first block 222. The first fixing part 220 is used for screwing in the second bolt to connect the first connecting part 22 to the first terminal 202. The second fixing part 230 penetrates the second mounting plate 231 and extends into the second block 232. The second fixing part 230 is used for screwing in the third bolt to connect the second connecting part 23 to the second terminal 203.

[0091] The second bolt is the bolt connecting the frame 2 to the first terminal 202 of the fuse 200, and the third bolt is the bolt connecting the frame 2 to the second terminal 203 of the fuse 200.

[0092] In one example, neither the first connecting part 22 nor the second connecting part 23 is connected to the base 1.

[0093] like Figure 10 As shown, the first connecting portion 22 and the second connecting portion 23 are distributed at both ends of the receiving portion 21 and are respectively connected to the receiving portion 21. The first connecting portion 22 has a first clearance area with the base 1, and the second connecting portion 23 has a second clearance area with the base 1. In this way, the aforementioned first clearance area and second clearance area can provide installation space for other components inside the battery pack, thereby improving the space utilization rate inside the battery pack.

[0094] In some possible embodiments, the fuse mounting 100 also includes a first reinforcing component 3.

[0095] like Figure 5 As shown, the fuse mounting component 100 also includes a first reinforcing component 3, which is located on the side of the receiving portion 21 away from the receiving cavity 210 and is connected to the base 1 and the receiving portion 21 respectively.

[0096] In some examples, the first reinforcing component 3 includes a plurality of first reinforcing ribs 31, which are spaced apart along a first direction.

[0097] The first direction is the direction from the first connecting part 22 to the second connecting part 23.

[0098] See Figure 5 The first reinforcing rib 31 has a plate-like structure, and its two adjacent wall surfaces are connected to the base 1 and the receiving part 21, respectively. This improves the connection strength between the base 1 and the receiving part 21.

[0099] For example, the first reinforcing component 3 includes six first reinforcing ribs 31, which are distributed at equal intervals along a first direction.

[0100] For example, the first reinforcing component 3, the base 1, and the frame 2 are integrally molded parts.

[0101] In some possible embodiments, the fuse mounting 100 also includes a second reinforcing component 4.

[0102] like Figure 6 and Figure 7 As shown, the second reinforcing component 4 includes a second reinforcing rib 41 and a third reinforcing rib 42. The second reinforcing rib 41 is connected to the receiving portion 21 and the first connecting portion 22, respectively. The third reinforcing rib 42 is connected to the receiving portion 21 and the second connecting portion 23, respectively.

[0103] Specifically, see Figure 4 and Figure 6 The second reinforcing rib 41 has a plate-like structure, and its three adjacent circumferential walls are respectively connected to the first mounting plate 221, the first block 222, and the first end of the receiving portion 21. (See also...) Figure 4 and Figure 5 The third reinforcing rib 42 has a plate-like structure, and the three adjacent walls of the third reinforcing rib 42 are respectively connected to the second mounting plate 231, the second block 232, and the second end of the receiving part 21.

[0104] In this way, by setting the second reinforcing component 4, the connection strength between the first connecting part 22 and the receiving part 21 can be improved, as well as the connection strength between the second connecting part 23 and the receiving part 21, thereby improving the overall strength of the frame 2.

[0105] In one example, the second reinforcing component 4 is also used to enhance the overall strength of the fuse mounting 100.

[0106] like Figure 4 and Figure 11 As shown, the second reinforcing component 4 includes a second reinforcing rib 41, which has a plate-like structure. One end of the second reinforcing rib 41 is connected to the receiving portion 21 and the first reinforcing rib 31, respectively. The other end of the second reinforcing rib 41 is connected to the first mounting plate 221, and the top of the second reinforcing rib 41 is connected to the first block 222. Figure 4 and Figure 12 As shown, the second reinforcing component 4 includes a third reinforcing rib 42, which has a plate-like structure. One end of the third reinforcing rib 42 is connected to the receiving part 21 and the first reinforcing rib 31, respectively. The other end of the third reinforcing rib 42 is connected to the second mounting plate 231, and the top of the third reinforcing rib 42 is connected to the second block 232.

[0107] In some possible embodiments, the base 1 has a clearance groove 14 located on the second wall surface 12 and arranged opposite to the receiving cavity 210. The clearance groove 14 is used to provide space for gripping the fuse 200.

[0108] Specifically, see Figure 4 and Figure 8 The clearance groove 14 can be a through groove structure, which can be square in shape, and the through groove structure connects the first wall surface 11 and the second wall surface 12.

[0109] In practice, by setting the clearance groove 14, technicians can pinch the two sides of the tube body 201 of the fuse 200 in the radial direction, thereby conveniently limiting the fuse 200, making it easier to tighten the bolts, and thus improving assembly efficiency.

[0110] The technical solutions provided in this disclosure have at least the following beneficial effects:

[0111] This disclosure provides a fuse mounting component 100. In the fuse mounting component 100, on the one hand, the base 1 and the frame 2 are connected without additional assembly, making the entire fuse installation process more convenient. On the other hand, the base 1 abuts against the bolt head of the first bolt through the abutment structure 131 provided inside the receiving hole 13, thereby achieving the connection between the fuse mounting component 100 and the battery pack housing. Compared to the related technology where the bolt head directly abuts against the wall of the base away from the housing, the change in the position of the second wall 12 does not change the electrical clearance between the fuse 200 and the first bolt. Therefore, while maintaining the same thickness of the base 1, the gap between the second wall 12 and the fuse 200 can be reduced, thereby reducing the overall size of the fuse mounting component 100 while meeting strength requirements.

[0112] This disclosure provides a fuse assembly including a fuse 200 and the aforementioned fuse mounting member 100.

[0113] like Figure 3 As shown, the fuse 200 includes a connected tube 201, a first terminal 202, and a second terminal 203. The tube 201 has a cylindrical structure. The first terminal 202 is located inside the tube 201 and at least partially extends out of the top surface of the tube 201. The second terminal 203 is located inside the tube 201 and at least partially extends out of the bottom surface of the tube 201. Further, see... Figure 3 The frame 2 includes a receiving portion 21, a first connecting portion 22, and a second connecting portion 23. The first connecting portion 22 and the second connecting portion 23 are located at both ends of the receiving portion 21 and are respectively connected to the receiving portion 21. Figure 4 The receiving part 21 has a receiving cavity 210, the shape of which is adapted to the shape of the outer wall of the tube 201.

[0114] Further, see Figure 8 The first terminal 202 is connected to the first connecting part 22 by bolts, and the second terminal 203 is connected to the second connecting part 23 by bolts. The tube body 201 is located inside the mounting cavity 201, and

[0115] The receiving part 21 is located on the second wall surface 12 of the seat body 1 and is connected to the seat body 1.

[0116] See Figure 3 and Figure 4 The receiving part 21 has a receiving cavity 210, the shape of which is adapted to the shape of the outer wall of the fuse 200.

[0117] The first terminal 202 and the second terminal 203 are respectively connected to the frame 2 by bolts. There is a gap 001 between the outer wall surface of the tube body 201 and the inner wall surface of the receiving cavity 210. Specifically, there are gaps 001 between the side wall of the tube body 201 and the arc surface of the receiving cavity 210, between the top surface of the tube body 201 and the first end of the receiving part 21, and between the bottom surface of the tube body 201 and the second end of the receiving part 21. The gap 001 is used to form a clearance between the tube body 201 and the receiving part 21, thereby providing space for heat dissipation of the tube body 201.

[0118] This disclosure provides a battery pack that includes the fuse assembly described above.

[0119] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
