Description

Technical Field

[0001] The utility model belongs to the technical field of battery packs, and specifically relates to a domain control battery pack socket assembly, an electrical connector and a domain control battery pack. Background Art

[0002] In existing new energy vehicles, battery packs, all-in-one controllers (MCU / OBC, etc.), BMS, etc. are mostly independently arranged in different positions of the vehicle, with low integration. A large number of wiring harnesses are required to connect the various devices, resulting in high cost of the connection harnesses.

[0003] In order to improve the integration of components and reduce the wiring harness connection between devices, a common arrangement is to integrate the battery and the domain controller (integrated VCU / MCU / BMS / TMS / PDU) into a battery box to form a domain control battery pack; or, as in the Chinese invention patent application with application publication number CN116365149A and application publication date June 30, 2023, part of the domain controller is integrated into the battery box, that is, part of the domain controller extends into the battery box. The integration of all or part of the domain controller with the battery box can effectively improve the integration of the battery and the domain controller and save the connection harness between the battery pack and the domain controller to a certain extent.

[0004] However, in the above scheme, since the battery and the domain controller are fully or partially integrated in one box, the battery is susceptible to the heating and electromagnetic interference of the domain controller, which in turn affects the thermal management and service life of the battery; in addition, according to statistics, the failure rate of the domain controller itself is higher than that of the battery. In the above integrated structure of the domain controller and the battery, when the domain controller is inspected and repaired, the battery box needs to be frequently disassembled, which not only increases the workload of inspection and repair, but also easily damages the waterproof performance and sealing performance of the battery pack box, thereby affecting the service life and reliability of the battery pack. As we all know, a high-voltage fuse is generally provided in the battery pack to connect and disconnect the high-voltage circuit. If the high-voltage fuse is provided inside the battery pack box, the same problem as the maintenance of the domain controller will be faced during maintenance; if an inspection port for replacing the high-voltage fuse is provided on the battery pack box, the sealing interface of the battery pack box will be increased, thereby reducing the sealing and reliability of the battery pack box.

[0005] As an improvement, a Chinese utility model patent with authorization announcement number CN219873887U and authorization announcement date October 20, 2023 discloses a domain control battery pack, including a battery compartment body provided with a first electrical plug-in (i.e., a socket assembly), a domain control compartment body provided with a second electrical plug-in (i.e., a plug assembly), and a guide mechanism, wherein the domain control compartment body approaches or moves away from the battery compartment body along the extension direction of the guide mechanism, so that the domain control module (i.e., the domain controller) and the battery are plugged in through the second electrical plug-in and the first electrical plug-in when the battery compartment body and the domain control compartment body are close to each other, thereby directly realizing the electrical connection between the battery and the domain control module. However, in this solution, since the battery and the domain control module are directly connected through the electrical plug-in, the front panel of the battery compartment body and the rear panel of the domain control compartment body are close to each other, and there is not enough space on the front panel of the battery compartment body for arranging the high-voltage fuse; how to ensure the convenience of high-voltage fuse maintenance while ensuring that the sealing performance and waterproof performance of the battery pack box are not damaged or reduced requires a suitable solution.

[0006] As a further improvement, a Chinese utility model patent with authorization announcement number CN219979972U and authorization announcement date November 7, 2023 discloses a high-voltage connector, including an inner shell (i.e., a substrate), a fuse and a socket terminal; at least part of the inner shell extends into the battery pack body; the fuse and the socket terminal are both arranged in the inner shell; the first terminal of the socket terminal is detachably connected to the first connection end of the fuse.

[0007] However, in the above scheme, the fuse and the socket terminal are both arranged in the accommodating portion of the inner shell, so that the fuse and the socket terminal share a sealing structure, which makes the single-seat waterproof performance of the fuse and the socket terminal poor. During maintenance, if the connector accidentally enters with water, it is easy to cause leakage or short circuit inside the connector; in addition, the inner shell is provided with a through hole for the conductors connected to the fuse and the socket terminal respectively to pass through, and the through hole is connected to the inner cavity of the battery pack case. If the battery pack case leaks or water enters, the liquid or water will enter the inner shell through the above-mentioned through hole, causing leakage or short circuit in the connector, and there are certain safety deficiencies.

[0058] like Figure 3 As shown, a second sealing structure is provided between the cover plate 32 and the fuse housing 33. Specifically, after the fuse is installed on the electrical connection column 39, the cover plate 32 is used to seal the open end of the fuse housing 33. In order to ensure the waterproof performance of the fuse, a second sealing ring 321 is provided between the cover plate 32 and the fuse housing 33, thereby ensuring the sealing of the contact between the cover plate 32 and the open end of the fuse housing 33, thereby improving the sealing of the fuse.

[0059] In this embodiment, the first sealing ring 331 and the second sealing ring 321 are both rubber rings; in other embodiments, the first sealing ring 331 and the second sealing ring 321 can be made of other suitable sealing materials, or the fuse housing 33 and the substrate 31, and the fuse housing 33 and the cover plate 32 can be sealed by means of sealant.

[0060] The fuse also includes a fuse body 6, both ends of the fuse body 6 have connection ends, and the fuse is installed on the electrical connection column 39 through the connection ends, and the electrical connection column 39 constitutes a mounting support for the fuse. Figure 2 As shown, the electrical connection column 39 has an extending section extending out of the fuse housing 33 and an intracavity section for connecting to the fuse body 6, and a third sealing structure is arranged between the extending section and the fuse housing 33. Specifically, the fuse is connected to the intracavity section of the electrical connection column 39 through a connecting end, and the bottom of the fuse housing 33 has an extending hole for the electrical connection column 39 to extend out. The extending section of the electrical connection column 39 passes through the extending hole and is connected to the positive or negative electrode of the high-voltage terminal 36 through a conductive member (not shown in the figure) to connect the fuse to the high-voltage circuit; in order to ensure the sealing between the electrical connection column 39 and the extending hole of the fuse housing 33, a third sealing ring (not shown in the figure) is arranged between the extending section of the electrical connection column 39 and the extending hole, which helps to achieve the single-seat waterproof performance of the fuse. In this embodiment, the conductive member is a copper bar or an aluminum bar, and the third sealing ring is a rubber ring; in other embodiments, the electrical connection column 39 and the fuse housing 33 are integrally injection molded, and the connection between the electrical connection column 39 and the copper bar or the aluminum bar is waterproofed by gluing.

[0062] like Figure 3 As shown, protective covers 62 are provided at the connection between the two ends of the fuse and the electrical connection column 39. Specifically, in order to meet the anti-electric shock protection when replacing the fuse, a plastic protective cover 62 that meets the IPXXB protection level is provided at the connection between the connection end of the fuse body 6 and the electrical connection column 39, thereby improving the anti-electric shock protection capability of the fuse.

[0063] A thermal pad 61 is provided between the cover plate 32 and the fuse. Specifically, a thermal pad 61 is provided between the cover plate 32 and the fuse body 6. The thermal pad 61 contacts the fuse body 6, which is conducive to heat dissipation of the fuse through the thermal pad 61 and the cover plate 32 when the fuse is working.

[0064] In order to improve the sealing performance and reliability between the socket 38 and the substrate 31, in this embodiment, a fifth sealing ring (not shown in the figure) is provided between the insulating member and the substrate 31, and the fifth sealing ring can be a rubber ring. In other embodiments, the fifth sealing ring can be made of other suitable sealing materials, or the insulating member and the substrate 31 can be sealed by means of a sealant. The fifth sealing ring provided between the insulating member and the substrate 31 helps the socket 38 achieve a single-seat IP68 protection level.

[0065] In order to improve the sealing performance of the connection between the socket assembly 3 and the battery pack 1 box, in this embodiment, as Figure 4 As shown, a fourth sealing structure is provided between the substrate 31 corresponding to the fuse installation position and the battery pack 1 case, and a sixth sealing structure is provided between the substrate 31 corresponding to the socket installation position and the battery pack 1 case.

By respectively providing the fourth sealing structure and the sixth sealing structure, the sealing performance of the socket 38 and the fuse can be effectively improved, thereby improving the sealing performance of the electrical connector and the battery pack 1.

[0066] In other embodiments, the fourth sealing ring 311 and the sixth sealing ring 312 may be made of other suitable sealing materials, or the socket installation area and the fuse installation area of ​​the substrate 31 may be sealed with the battery pack 1 body by means of sealants.

[0067] It should be understood that the sealing structure between the substrate 31 and the battery box can select a suitable structural form according to actual conditions so as to achieve separate sealing of the socket 38 and the fuse, and this is not limited in the present embodiment.

[0068] In this embodiment, the fourth sealing ring 311 has the same structure as the first sealing ring 331 .

[0070] In this embodiment, the fifth sealing ring, the sixth sealing ring 312 and the seventh sealing ring 341 constitute a socket installation position sealing structure. Through the cooperation of the socket installation position sealing structures at different positions, the waterproof performance and sealing performance of the socket 38 are improved, and the single seat sealing of the socket 38 is achieved.

[0071] Embodiments of the electrical connector in the utility model:

[0072] In this embodiment, the electrical connector includes a plug assembly and a socket assembly.

[0073] It should be noted that the structure of the socket assembly is consistent with the socket assembly structure in the embodiment of the domain control battery pack socket assembly in the present invention, and will not be described in detail here.

It should be noted that the assembly method of each jack and the plug housing 51 is a known technology in the art and will not be described in detail here.

[0075] After the plug assembly 5 and the socket assembly 3 are plugged into each other, the high-voltage terminal 36 is used to connect the high-voltage main circuit of the battery pack and the domain controller, the heating terminal 35 is used to connect the heating film in the battery pack and the thermal management circuit of the domain controller, and the low-voltage terminal 37 is used to connect the BMS slave control in the battery pack and the BMS master control in the domain controller. During the coupling process of the plug assembly 5 and the socket terminal of the socket assembly 3, the engagement sequence of each terminal is a known technology in the art and will not be described in detail here.

[0076] In order to improve the accuracy of coupling between the socket 38 of the socket assembly 3 and the plug assembly 5, a bowl-shaped mouth 53 structure is provided on the plug shell 51, so that when the socket 38 and the plug assembly 5 are coupled, the socket shell 34 cooperates with the bowl-shaped mouth 53 structure of the plug shell 51 to achieve precise docking between the plug assembly 5 and the socket 38, thereby improving the coupling efficiency.

[0082] It should be noted that the structure of the electrical connector in this embodiment is consistent with the structure of the electrical connector in the embodiment of the electrical connector of the utility model, and will not be described in detail here.

[0083] like Figure 8 As shown, the domain control battery pack also includes a mounting bracket 4 for mounting the domain controller 2 protruding outwardly along the battery pack 1 box; specifically, the mounting bracket 4 protrudes outwardly along the length direction of the bottom plate of the battery pack 1 box, and the mounting bracket 4 and the bottom plate are integrally formed.

[0084] In other embodiments, the mounting bracket 4 and the base plate may be separate structures, and the mounting bracket 4 is connected to the base plate by welding; the mounting bracket 4 may protrude outward from the side wall of the battery pack 1 box, and the specific structure may be the side wall structure in CN219873887U, so that the domain controller 2 is installed between the two protruding side walls.

[0085] In the above embodiment, by setting the mounting bracket 4 on the battery pack 1 case, the domain controller 2 can be brought closer to the battery pack 1, thereby reducing the connection wiring harness between the battery pack 1 and the domain controller 2, and effectively reducing the cost of the electrical connectors between the battery pack 1 and the domain controller 2; at the same time, the stability and reliability of the connection between the domain controller 2 and the battery pack 1 case can be improved.

Therefore, when the domain controller 2 is fixed to the mounting bracket 4, the cooperation between the guide groove 41 and the guide column 22 can achieve a guiding effect during the installation of the domain controller 2, thereby ensuring that the plug assembly 5 and the socket assembly 3 can be accurately aligned to be plugged into each other to achieve electrical connection.

[0087] The mounting bracket 4 and the domain controller 2 are provided with positioning holes 43 correspondingly. When the domain controller 2 is installed, when the positioning holes 43 of the mounting bracket 4 correspond to the positioning holes 43 of the domain controller 2, the domain controller 2 is locked at the set position in the length direction of the battery pack 1 case by the positioning pin, and then the domain controller 2 is connected to the mounting bracket 4 by bolts passing through the domain controller mounting holes 42, thereby achieving a fixed connection between the domain controller 2 and the battery pack 1 case. The battery pack 1 and the domain controller 2 are connected by a quick-change electrical connector, which improves the convenience of maintenance; at the same time, the domain controller 2 and the battery pack 1 are respectively arranged in independent cases, which can effectively prevent the battery from being affected by the heating and electromagnetic interference of the domain controller 2.

[0088] The mounting bracket 4 is provided with a weight-reducing hole on one side close to the battery pack 1 box, and a weight-reducing notch on the side away from the battery pack 1 box, so as to effectively reduce the weight of the mounting bracket 4, thereby helping to reduce the weight of the domain controller battery pack. It should be understood that the weight-reducing hole and the weight-reducing notch can also be used as the bottom heat dissipation channel of the domain controller 2.

[0089] When inspecting the domain controller 2 or the fuse, remove the bolts connecting the domain controller 2 and the mounting bracket 4, pull the domain controller 2 away from the battery pack 1, and disconnect the electrical connector. The domain controller 2 or the fuse can then be inspected separately, reducing the impact of the inspection of the domain controller 2 or the fuse on the waterproof performance and sealing performance of the battery pack 1.

The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
