It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0031] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0033] As mentioned in the background, battery modules are crucial components for generating power in electric vehicles. Managing the power within these modules is crucial for electric vehicles, and specialized battery management systems and electrical components are typically used to manage these components. The primary function of these components in the battery pack is to protect, control, and monitor its safety and performance.

[0034] Among them, shunts and fuses are usually electrical components without bases. In the integrated electrical component grouping method BDU (Battery Disconnect Unit), other auxiliary structural components are needed to complete the connection and installation in the entire circuit package.

[0035] The electrical components can be understood as shunts or fuses. Shunts' primary functions include accurately measuring current, controlling its magnitude and direction, regulating voltage, improving battery stability and safety, and providing strong anti-interference capabilities. A fuse's primary function is to quickly disconnect the circuit in the event of an internal battery fault, preventing excessive current from flowing through the battery and thus protecting the battery and surrounding equipment.

[0036] In the prior art, the previous integrated electrical component grouping method required a large space for the battery pack envelope, and the high-voltage connection inside the battery pack was complex and costly.

[0037] Compared with the integrated electrical component grouping method, although the distributed arrangement of electrical components effectively utilizes the spatial structure within the battery pack, simplifies the high-voltage connection direction, and effectively reduces costs, the distributed arrangement of electrical components can achieve safe and effective constraints on shunts and fuses. At the same time, simple installation structural parts are particularly important, but there is no suitable structure to facilitate the installation of electrical components.

[0038] In view of this, please refer to Figure 1-Figure 3 The support base 100, support structure and battery pack provided in the embodiment of the present invention can solve this problem, which will be described in detail below.

[0039] A battery pack is provided in an embodiment of the present invention. The battery pack includes electrical components and a support structure. The electrical components in the battery pack can be arranged in a distributed manner, making full use of the space enclosed by the battery pack.

[0040] Of course, the battery pack also includes a battery pack shell, and the support structure can be arranged in the battery pack shell.

[0041] The electrical components are arranged on the mounting plate 200 of the support structure. Specifically, the support structure includes the mounting plate 200 and at least one support base 100 . The connector 120 (described in detail below) of at least one support base 100 is connected to the mounting plate 200 .

[0042] The support structure has the advantage of being simple in structure, and can facilitate installation of different electrical components (such as the shunt 10 or the fuse) in the housing of the battery pack through the support structure. At the same time, the support structure provides safe and effective constraints for the electrical components.

[0043] In other words, the support base and the support structure have a certain degree of versatility and can realize the installation of different electrical components. Among them, the number of support bases 100 can be multiple, and the connectors 120 of multiple support bases 100 are simultaneously connected to the mounting plate 200. Here, multiple can be understood as at least two. In this embodiment, the number of support bases 100 is two.

[0044] Of course, in other embodiments, the number of the support bases 100 may also be three, four, or five.

[0045] Specifically, the support base 100 includes a base body 110 and a connecting member 120. The bottom of the base body 110 is provided with a fixing hole 1121 and a groove 1111. The groove 1111 and the fixing hole 1121 are distributed at intervals. The connecting member 120 is arranged at the top of the base body 110. The connecting member 120 is used to connect the mounting plate 200, and the electrical components can be installed on the mounting plate 200.

[0046] Since the support base 100 has a fixing hole 1121, the bolt 400 can pass through the fixing hole 1121 and connect to the battery pack shell, thereby facilitating the installation of electrical components in the battery pack. In addition, a groove 1111 is provided at the bottom of the base body 110, which can save materials for making the base body 110.

[0047] It should be noted that a mounting groove is provided at the top of the base body 110 (which can be understood as the top of the support block 111), and part of the structure of the connecting member 120 is arranged in the mounting groove. In this embodiment, the connecting member 120 includes an inlay head (not shown), a flange 121 and a threaded rod 122 connected in sequence. The inlay head is arranged in the mounting groove at the top of the base body 110, and the threaded rod is used to connect the mounting plate 200. That is to say, the head of the connecting member 120 (i.e., the inlay head) is inlaid in the mounting groove. Optionally, the peripheral wall of the inlay head may also have an annular tooth structure.

[0048] It is easy to understand that the connecting member 120 in this embodiment can be understood as an integrated flange bolt.

[0049] It is easy to understand that the support structure may include a bolt 400 , and each fixing hole 1121 is provided with a bolt 400 .

[0050] It should be noted that, in this embodiment, the base body 110 includes a support block 111 and at least one fixing member 112, the fixing member 112 is connected to the support block 111, the fixing member 112 is provided with a fixing hole 1121, the support block 111 is a rectangular block structure, the bottom of the support block 111 is provided with a groove 1111, and the connecting member 120 is arranged on the top of the support block 111.

[0051] In this embodiment, there are two fixing members 112 , which are disposed on opposite sides of the support block 111 . Of course, in other embodiments, there may be only one fixing member 112 .

[0052] There are multiple grooves 1111 , and the multiple grooves 1111 can be distributed in a matrix. This can reduce the material required to make the base body 110 , avoid molding deformation of the base body 110 , and improve the structural strength of the base body 110 .

[0053] In this embodiment, the number of the grooves 1111 is four. Of course, in other embodiments, the number of the grooves 1111 can also be two, five, or six, etc. In addition, in this embodiment, the four grooves 1111 are all rectangular grooves 1111.

[0054] It is easy to understand that in this embodiment, in order to facilitate the installation of the mounting plate 200 on the connecting member 120, the mounting plate 200 is provided with two through holes, and the threaded rods 122 of the two connecting members 120 respectively pass through the two through holes, and the supporting structure also includes two flange nuts 300, and then a flange nut 300 is screwed onto the threaded rods 122 of the two connecting members 120 respectively.

[0055] The two flanges 121 can both bear the mounting plate 200 .

[0056] Generally speaking, during the installation of electrical components, the bolts 400 can be passed through the fixing holes 1121 and then connected to the battery pack shell (which can be understood as the lower shell), and then the mounting plate 200 with the electrical components (such as the diverter 10) installed is set on the two connecting parts 120, and finally the flange nuts 300 are screwed on the two connecting parts 120 respectively, and finally the electrical components are connected to the soft connection to complete the assembly of the electrical components.

[0057] To sum up, the support seat 100 includes a seat body 110 and a connecting member 120. The bottom of the seat body 110 is provided with a fixing hole 1121 and a groove 1111. The groove 1111 and the fixing hole 1121 are distributed at intervals. The connecting member 120 is arranged on the top of the seat body 110. The connecting member 120 is used to connect the mounting plate 200.

[0058] The electrical components can be installed on the mounting plate 200. Since the support base 100 has a fixing hole 1121, the bolt 400 can pass through the fixing hole 1121 and connect to the battery pack shell, thereby facilitating the installation of the electrical components in the battery pack. In addition, a groove 1111 is provided at the bottom of the base body 110, which can save materials for making the base body 110.

[0059] Among them, the number of grooves 1111 of the support seat 100 can be multiple, and the multiple grooves 1111 can be distributed in a matrix. In this way, the material required to make the seat body 110 can be reduced, while avoiding the molding deformation of the seat body 110 and improving the structural strength of the seat body 110.

[0060] In addition, a mounting groove is provided on the top of the support block 111, and part of the structure of the connecting member 120 is arranged in the mounting groove. The connecting member 120 includes an inlay head (not shown in the figure), a flange 121 and a threaded rod 122 connected in sequence. The inlay head is located in the mounting groove at the top of the base body 110, and the threaded rod is used to connect the mounting plate 200. That is to say, the head of the connecting member 120 (i.e., the inlay head) is embedded in the mounting groove to facilitate the installation of the connecting member 120.

[0061] The support structure includes a mounting plate 200 and at least one of the above-mentioned support bases 100 . The connecting member 120 of at least one of the support bases 100 is connected to the mounting plate 200 . The support structure has all the functions of the above-mentioned support bases 100 .

[0062] The battery pack includes electrical components and the above-mentioned support structure. The electrical components are arranged on the mounting plate 200 of the support structure. The battery pack has all the functions of the above-mentioned support structure.

[0063] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
