The purpose is to better illustrate the embodiments that may cover the specific examples in combination with the specific examples, rather than being limited to the specific examples.

[0040] In the prior art, when charging a storage battery, it is necessary to connect an external charging device to the terminal post of the storage battery, and the terminal post is not suitable for externally connecting a fixed charging device. The reasons include but are not limited to: when charging the storage battery, the external charging device falls off due to the lack of a fixed area or the fixed area not being suitable for fixing the external charging device. Specifically, for example, the surface of the terminal post is relatively smooth and it is difficult to fix the external charging device, or for another example, the terminal post is relatively short, resulting in interference between the surrounding components and the external charging device when the charging device is connected to the terminal post. It can be seen that it is difficult to connect the terminal post of the storage battery and the storage battery with a fuse box installed thereto to an external charging device.

[0041] Based on this, the present application further provides an adapter 320. At least part of the adapter 320 is electrically connected to the positive output terminal of the storage battery, and the remaining part is used for externally connecting to an external charging device; when the external charging device is connected to the adapter 320, the adapter 320 enables electrical connection between the external charging device and the storage battery. The adapter is adapted to fix the external charging device, which can reduce the difficulty of connecting the external charging device to the storage battery and improve the connection stability.

[0042] Next, refer to Figures 1 - 6 Describe the fuse box 300 and the vehicle according to the embodiments of the present application.

[0043] First, refer to Figure 1 and Figure 3 As shown, the fuse box 300 according to the embodiments of the present application includes: a body 310 and an adapter 320.

[0044] Among them, the body 310 has a bus bar 311 electrically connected to the storage battery; the adapter 320 is connected to the body 310. One end of the adapter 320 is connected to the bus bar 311, and the other end of the adapter 320 extends away from the body 310, and the other end of the adapter 320 is used for connecting to an external charging device.

[0045] Further in combination with Figure 6As shown, the external charging device can be a charging clip connected to a power source, or a wire connected to a power source, or a fixing sleeve, a fixing ring, etc. connected to an external power source. Specifically, the structure of the external charging device connected to the adapter can be Figure 6 In the charging clip shown, the adapter 320 is partially connected to the bus 311 and the rest of it extends in a direction away from the main body 310, and the end away from the main body 310 is formed as a part that can replace the pole 110 as a charging connector; in other words, the adapter 320 is partially connected to the bus 311 and partially connected to the external charging device, and the adapter 320 itself forms a channel that can conduct current, and the charging clip is clamped on the adapter to achieve electrical connection between the external charging device and the battery.

[0046] It is worth mentioning that the end of the adapter 320 away from the body 310 described in the embodiment of the present application should not be limited to only include the end, but should be understood to include the end and a partial area next to the end, and the corresponding area protrudes relative to the fuse box to facilitate the external connection of an external charging device; for example, it is formed as a column or a tilted structure relative to the body 310. The connection of the adapter to the bus 311 should not be limited to being directly connected. The connection of one end of the adapter 320 to the bus 311 should actually be understood as an electrical connection between the two, that is, other conductive materials can be spaced between the bus 311 and the adapter 320, for example, one end of the adapter 320 is connected to the pole 110 instead of being directly connected to the bus 311. It can be understood that in order to achieve the purpose of electrical connection, the adapter 320 is preferably a conductive material, such as an alloy material, copper, etc.

[0047] According to the fuse box 300 of the embodiment of the present application, the fuse box 300 is provided with an adapter 320, and is electrically connected to the external charging device through the adapter 320, thereby reducing the difficulty of electrical connection between the external charging device and the battery, that is, providing a fixed point for the external charging device while guiding current, reducing the difficulty of electrical connection of the external charging device and improving the stability of electrical connection.

[0048] According to a further example of the embodiment of the present application, reference Figures 1 - 2 As shown, the adapter 320 includes a first connection portion 321, and the adapter 320 is connected to the bus 311 through the first connection portion 321. The adapter 320 can be used as a part of the fuse box 300. Specifically, the first connection portion 321 is detachably connected to the bus 311. In some scenarios, when manufacturing the fuse box 300 or manufacturing the battery 100 having the fuse box 300, the first connection portion 321 is installed on the body 310 of the fuse box 300; or the adapter 320 is used as a spare part to be assembled, and is installed on the body 310 of the fuse box 300 when the battery 100 needs to be charged.

[0049] It can be understood that, as a detachable part in the fuse box 300, the first connection part 321 can facilitate production and maintenance on the one hand. For example, the adapter 320 can be produced separately and then configured in the fuse box of any kind of storage battery. When the adapter is damaged, only the adapter 320 needs to be replaced while the remaining components of the fuse box are retained.

[0050] In some other examples, the first connection part 321 can also be completely fixed to the bus bar 311. For example, the first connection part 321 is integrally formed on the bus bar 311. Next, two examples will be described based on the structure in which the first connection part 321 is detachably connected to the bus bar 311.

[0051] In some examples, referring to Figure 1 and Figure 3 as shown, the first connection part 321 is configured as a connecting plate, and mounting holes are formed thereon. The connecting plate is attached to the bus bar 311 and fastened by fasteners. Specifically, the fasteners pass through the mounting holes and press the connecting plate against the bus bar 311. Exemplarily, the fasteners are bolts, and blind holes matching the mounting holes are formed on the bus bar 311. The bolts press the connecting plate against the surface of the bus bar 311.

[0052] It can be understood that the flat structure of the connecting plate attached to the bus bar 311 can increase the contact area and improve the conductive effect. Moreover, by the way of fixing the connecting plate to the bus bar 311 with fasteners, the connecting plate and the bus bar can be pressed tightly to reduce the gap, and the situation of overhigh local temperature caused by the loose connection between the connecting plate and the bus bar 311 can be avoided.

[0053] In some other examples, the first connection part 321 is made of magnetic material, and the first connection part 321 is configured with a planar structure adapted to the bus bar 311. Specifically, when the first connection part 321 is a magnetic attraction material such as a magnet, and at the same time the bus bar 311 is made of magnetic metal, after the first connection part 321 approaches the bus bar 311, the first connection part 321 and the bus bar 311 are magnetically attracted and conduct electricity.

[0054] It can be understood that configuring the first connection part 321 as a magnetic part adapted to be magnetically attracted to the bus bar can be used as a common part, and it is matched to the bus bar when charging the storage battery, which is convenient for use and disassembly and installation.

[0055] It can be seen that the detachable connection structure between the first connection part 321 and the bus bar 311 can be in a variety of different ways, and the examples of the present application should not be limited to a specific connection method.

[0056] In a further example according to an embodiment of the present application, the adapter is electrically connected to an external charging device through the second connecting portion 322, and the second connecting portion 322 is configured as a connecting column. Specifically, the connecting column has a circumferential side wall and two end faces in the axial direction, wherein the side wall is convenient to be clamped or sleeved. For example, if the column is set as a hexagonal column, a clamping member with a planar clamping structure can be used to clamp the two opposite planes of the hexagonal column. Another example is that when the side wall is a cylindrical surface, the external charging device is configured with a ring body, and the hole at the center of the ring body is sleeved and matched with the cylindrical surface and then connected.

[0057] It can be understood that the connecting column can be adapted to the charging ends of various external charging devices. Directly connecting the charging end of the external charging device to the side wall of the column is convenient and fast, and the side wall area is relatively large, which is convenient for users to perform the connection operation.

[0058] In a further example, a limiting portion 323 extending in the axial direction is provided on the circumference of the connecting column. In this example, the circumferential side wall of the connecting column is also matched with the external charging device. Different from the previous example, the limiting portion 323 opened in the circumferential direction in this example can be adapted to and cooperate with the charging end of the external charging device.

[0059] It can be understood that the fixing mechanism formed by the cooperation of the limiting portion 323 and the charging end is also arranged axially. The limiting portion 323 extending in the axial direction can prevent the charging end from rotating circumferentially, so that the charging end is stably connected to the connecting column. Next, the specific structure of the limiting portion 323 will be illustrated by examples.

[0060] In some examples, the limiting portion 323 is configured as a protrusion formed on the circumferential side of the connecting column, and the protrusion extends along the axial direction of the connecting column. Specifically, the protrusion can be a rib extending along the axial direction of the connecting column. The protruding limiting portion 323 can be matched with a charging end having a concave or toothed structure, and when the charging end is a ring structure or other structures, it can also form a cooperation by means of an embedding fit with the protrusion.

[0061] In some examples, the limiting portion 323 is configured as a plurality of limiting blind slots formed on the circumferential side of the connecting column, or the limiting portion 323 is configured as a limiting through slot formed on the circumferential side of the connecting column. Similarly, the plurality of groove structures provided on the connecting column can also provide auxiliary fixation for the charging end, which will not be elaborated here.

[0062] In a specific example, referring to Figure 3 As shown, the connecting column is an annular column body, and a limiting through slot is provided on the side of the annular column body far from the first connecting portion 321. Specifically, the limiting through slot is formed as an opening structure on the annular column body. The opening structure in this example can provide an auxiliary fixing point for the charging end, and after a part of the structure of the charging end is fitted into the opening structure, it is stably connected to the fixing column.

[0063] According to a further example of the embodiment of the present application, the second connection portion 322 and the first connection portion 321 in the above example can form an integral structure or be connected in other ways, and the second connection portion 322 is formed as a column structure to facilitate external connection to an external charging device. Figure 1 and Figure 2 As shown, the first connection part 321 and the second connection part 322 can be connected through the bending part 324, and the bending part 324 makes the first connection part 321 and the second connection part 322 have an angle; take the first connection part 321 as a connecting plate as an example for explanation, the bending part 324 is bent relative to the connecting plate to form a tilting structure, and the bending part 324 can be formed into a tilting structure away from the bus 311 and the connecting plate, so that the second connection part 322 is formed into a connecting column away from the bus 311 and the first connection part 321. More specifically, the angle formed between the first connection part 321 and the second connection part 322 is a right angle, and the connecting column extends upward perpendicularly relative to the bus 311 and the connecting plate to form an external charging terminal.

[0064] It is understandable that after the first connection portion 321 and the second connection portion 322 are connected to form an angle, the second connection portion 322 can form a protruding structure relative to the fuse box 300. For example, the two are connected by the bending portion 324, and the second connection portion can be a connecting column suitable for matching with the charging end of the external charging device. The bending portion 324 extends the second connection portion 322 outside the fuse box 300, which can avoid interference between the charging end and other components of the fuse box 300.

[0065] According to a further example of the embodiment of the present application, reference may be made to Figure 4 It is understood that the fuse box 300 also includes a cover 400, which is covered on the body 310, and a receiving space is defined between the body 310 and the cover 400, and the adapter 320 is arranged in the receiving space. Specifically, the cover includes a first cover 410 and a second cover 420, and the first cover 410 is arranged on a plane on one side of the battery where the pole is arranged, and the first cover 410 is used to cover the adapter and the pole; the second cover 420 is used to cover the rest of the fuse box, such as other areas of the rectifier bar.

[0066] In one exemplary embodiment, reference may be made to Figure 5 To understand the structure of the fuse box, the fuse box 300 is arranged at the positive electrode of the storage battery 100, and the positive electrode column 110 at the positive electrode is provided with a positive battery plug 312, and the positive battery plug 312 is spliced ​​with the bus bar 311. The positive battery plug 312 is fixed to the fuse box 300 by a set of bolts, specifically including a first bolt 313 and a second bolt 315, the first bolt 313 is matched with a first nut 314, and the second bolt 315 is matched with a second nut 316.

[0067] Continue to combineFigure 5 It is understood that the first connecting portion 321 is a connecting plate, a mounting hole is provided at the center of the connecting plate, a first threaded hole matching the first bolt 313 is provided in the positive battery plug 312, and the mounting hole and the first threaded hole in the example are both used to pass the first bolt 313, and the first thread is fixed in the first threaded hole. Specifically, a gasket 317 is provided under the first nut 314, and a connecting plate and a part of the plate body of the bus 311 are provided between the gasket 317 and the positive battery plug in sequence. When in use, the first nut 314 is tightened to press the connecting plate between the gasket 317 and the bus 311.

[0068] The second connecting portion 322 is an annular column, and the bending portion 324 is an arc-shaped piece extending from the end of the annular column. The two ends of the arc-shaped piece are respectively connected to the connecting plate and the end of the annular column to form an integral structure. The limiting portion 323 arranged on the annular column is an open structure as shown in the figure.

[0069] In an exemplary usage scenario, combined with Figure 6 As shown, the external charging device is a charging clamp 200, and the charging end of the external charging device is the clamping head portion 210 of the charging clamp 200. The clamping head portion is connected to a handle portion 220, and the handle portion 220 is used to control the clamping action of the clamping head portion. In this exemplary scenario, a conventional charging clamp 200 is used, and its clamping head portion 210 is provided with a serrated structure 211. It can be understood that the serrated structure 211 can be engaged with the edge of the arc-shaped plate body of the annular cylinder opening, and a stable connection structure is formed with the edge through the irregular serrated structure 211.

[0070] Therefore, when the battery 100 needs to be charged, the user does not need to clamp the charging clip 200 to the pole 110 for charging, but instead clamps the clamping head portion 210 of the charging clip 200 to the annular column shown in the figure. The serrated structure 211 of the clamping portion is stably engaged with the opening structure and then powered on, which can prevent the charging clip 200 from falling off during the charging process.

[0071] A vehicle according to an embodiment of the present application includes a battery 100 and a fuse box 300 described in any of the above examples, and the fuse box 300 is arranged on the positive pole 110 of the battery 100. It is not difficult to understand that in a conventional vehicle, when the battery 100 of the vehicle is low on power and needs to be directly charged, the user can only clamp the charging clip 200 to the pole 110 of the vehicle. Since the pole 110 is not suitable for fixing the charging clip 200, the charging clip 200 often falls off. In the embodiment of the present application, an adapter 320 is arranged on the fuse box 300 of the battery 100, and the user can clamp the charging clip 200 to the adapter 320 to achieve stable clamping.

[0073] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the claims and their equivalents.
