Description

Technical Field

[0001] This utility model relates to the technical field of integrated panels on battery packs, and in particular to an integrated panel. Background Technology

[0002] With the rapid development of the national new energy vehicle industry, there are increasingly higher requirements for the cost reduction and high functional integration of battery packs in new energy vehicles, as well as for the convenience of after-sales maintenance of power batteries. The electrical connections on the battery pack include high-voltage connections for the positive and negative terminals, fuses for circuit protection, and low-voltage signal connections. As energy storage systems continue to mature, miniaturization is also required for these electrical connections.

[0003] For example, Chinese patent CN117791023A discloses an integrated panel, including a panel body. The panel body integrates a low-voltage interface, a fuse interface, and a high-voltage connector interface. A low-voltage connector is connected to the low-voltage interface, a fuse is connected to the fuse interface, and a high-voltage connector is connected to the high-voltage connector interface. The positive terminal of the high-voltage connector is connected to the fuse. Integrating the low-voltage interface, fuse interface, and high-voltage connector interface onto the panel body compactly arranges the electrical connections of the battery pack onto the panel body, reducing the occupied volume and achieving miniaturization. This solves the technical problem in the prior art where the electrical connections of the battery pack are distributed in different spatial locations, occupying a large volume and resulting in a non-compact structure. The aforementioned disclosure compactly arranges the low-voltage connector, fuse, and high-voltage connector onto the panel body, reducing the occupied volume and achieving miniaturization.

[0004] However, paragraph 0044 of the aforementioned publicly available document states that "the panel body is provided with embedded nuts, and the copper busbars are connected to the embedded nuts on the panel body by screws. The embedded nuts make the high-voltage connector more securely fixed and can better withstand the force generated by the copper busbars after the bolts are tightened, thus improving safety performance." In other words, to transfer the force on the copper busbars to the panel housing and enhance the overall strength of the connector, the copper busbars are fixed to the panel body using embedded nuts. This requires repeatedly tightening the bolts towards the embedded nuts to achieve the fixation between the copper busbars and the panel body. However, in actual production, it has been found that this fixing method results in a long assembly time, which is not conducive to improving assembly efficiency. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes an integrated panel, which solves the technical problem of long assembly time in existing integrated panels where copper busbars are fixed to the panel body by embedded nuts.

[0006] The technical solution of this utility model is implemented as follows: An integrated panel includes a panel body, on which a positive terminal, a negative terminal, and a fuse assembly are provided. The fuse assembly is located between the positive terminal and the negative terminal. The panel body is provided with a positive copper busbar, a negative copper busbar, and a fuse copper busbar. The positive copper busbar is connected to the positive terminal, and the negative copper busbar is connected to the negative terminal. One end of the fuse assembly is connected to the positive copper busbar, and the other end is connected to the fuse copper busbar. The positive copper busbar and the fuse copper busbar are both connected to the panel body by insert injection molding. This application connects the positive electrode copper busbar and the fuse copper busbar to the panel body through insert injection molding. This insert injection molding method replaces the existing fixing method of fixing the copper busbar to the panel body with insert nuts. The insert injection molding method eliminates the need to repeatedly tighten the bolts towards the insert nuts to fix the copper busbar to the panel body, thus shortening the assembly time and improving the assembly efficiency. It also transfers the force of the copper busbar inside the battery pack to the panel shell, enhancing the overall strength of the connector while saving assembly time. This solves the technical problem of long assembly time in the existing fixing method of fixing the copper busbar to the panel body with insert nuts on integrated panels.

[0007] Preferably, the panel body has at least two positive connection terminals, both of which are connected to the positive copper busbar; the panel body also has at least two negative connection terminals, both of which are connected to the negative copper busbar. The panel body has at least two positive connection terminals and at least two negative connection terminals, meaning the number of positive and negative connection terminals on the panel body can be selected as needed, with the number of positive and negative connection terminals being the same. When the panel body has two positive connection terminals and two negative connection terminals, the two high-voltage positive terminals, two high-voltage negative terminals, and the fuse assembly on the panel body are integrated into a single structure. When the panel body is provided with two negative electrode connection terminals, the negative electrode copper busbar is a Y-shaped structure formed by riveting two copper busbars together. The two copper busbars are riveted together and then assembled onto the panel body and connected to the two negative electrode connection terminals respectively, realizing the parallel connection of two high-voltage negative electrodes. At the same time, the positive electrode copper busbar is provided with two connection terminals, and the two connection terminals on the positive electrode copper busbar are connected to the two positive electrode connection terminals respectively, realizing the parallel connection of two high-voltage positive electrodes.

[0008] Preferably, both the positive and negative connection terminals include a base housing. The base housing contains terminals for connecting wires. A tail cap is connected to the base housing. Between the base housing and the tail cap are provided positive and negative shields, a shielding insulator, an inner shielding ring, an outer shielding ring, a sealing body, and a gasket for being fitted onto the wire. The positive and negative shields are fitted over the outer side of the shielding insulator. The inner and outer shielding rings are pressed onto the wire and then inserted into the shielding insulator, making contact between the shielding rings and the spring contacts of the positive and negative shields (6 contact points). The sealing body and gasket are placed side-by-side inside the tail cap. The base housing is integrally connected to the panel body. An opening is provided inside the base housing, and the terminals are located within the opening. A top cover is connected to the base housing by screws, sealing the opening. The wire passes through the tail cap, extends into the opening, and connects to the terminals. The tail cap is used to secure the wire.

[0009] Preferably, the base housing and the tail cap are threaded together; the tail cap is a gland head. The threaded connection between the base housing and the tail cap improves the ease of installation and removal. The tail cap is a gland head because gland heads have a compact structure and high tensile strength.

[0010] Preferably, the bottom surface of the panel body is provided with a shielding groove, and a shielding spring is snapped into the shielding groove. The shielding spring contacts the positive and negative electrode shields. The shielding spring is provided to achieve normal shielding performance after the panel body is installed on the battery pack. The positive and negative electrode shields are provided with axially extending connecting parts. When the positive and negative electrode shields and the shielding spring are installed on the panel body, the connecting parts on the positive and negative electrode shields contact the top of the shielding spring. When the panel body is installed on the battery pack, the bottom of the shielding spring contacts the shield on the battery pack, forming overall shielding for the battery pack.

[0011] Preferably, the panel body has a fixed cavity for inserting a fuse assembly. The fuse assembly includes a handle housing adapted to the fixed cavity, and a fuse is housed within the handle housing. Both ends of the fuse are connected to socket contacts. The socket contact at one end of the fuse engages with the positive copper busbar, and the socket contact at the other end engages with the fuse busbar. The fuse is designed to quickly disconnect the circuit between the positive copper busbar and the fuse busbar when a short circuit causes a sharp increase in current, preventing equipment overload or burnout. The handle housing is designed to protect the fuse.

[0012] The fuse assembly has a receptacle finger protector at the bottom, which is located in the fixed cavity. The receptacle finger protector can not only prevent finger contact with the fuse assembly's pins, but also guide the pins during insertion, reduce the insertion force, and facilitate insertion.

[0013] Preferably, the fuse has a cover plate at its bottom, which is connected to the handle housing. The end of the cover plate provides limiting support for the socket contact. The cover plate is provided to abut and support the fuse, ensuring the stability of its position. The end of the cover plate also provides limiting support for the socket contact, further ensuring the stability of the fuse's position.

[0014] Preferably, a sealing ring is provided between the handle housing and the panel body, and a fixing groove is provided on the handle housing, with the sealing ring located within the fixing groove. The sealing ring further ensures the sealing performance after the handle housing and the panel body are assembled.

[0015] Preferably, a panel rubber ring is provided on the bottom surface of the panel body. The panel rubber ring is provided to ensure the sealing performance of the panel body after assembly.

[0016] Preferably, the panel body is provided with a limiting groove, the panel rubber ring is located in the limiting groove, the panel rubber ring is provided with a hanging platform, the limiting groove is provided with a protruding rib and a stop groove, the hanging platform and the stop groove are engaged, and the panel rubber ring and the protruding rib are interference-fitted. The stop groove is connected to the limiting groove, and the protruding rib is located in the limiting groove. When the hanging platform and the stop groove are engaged, and the panel rubber ring and the protruding rib are interference-fitted, the panel rubber ring is more stably confined within the limiting groove, ensuring the stability of the panel rubber ring's position.

[0017] The panel rubber ring has an integrally connected sealing area, which is set on the panel body and surrounds the shielding spring to seal and protect the shielding spring. This application achieves the goal of sealing and protecting the shielding spring at the same time as sealing the panel body after assembly.

[0018] The beneficial effects of this utility model are: 1. This application connects the positive electrode copper busbar and the fuse copper busbar to the panel body by insert injection molding. The insert injection molding method replaces the existing fixing method of fixing to the panel body by insert nuts. The insert injection molding method does not require repeated tightening of bolts towards the insert nuts to fix the copper busbar to the panel body, which shortens the assembly time and improves the assembly efficiency. It also transfers the force of the copper busbar inside the battery pack to the panel shell, enhances the overall strength of the connector, and saves assembly time.

[0019] 2. This application provides a limiting groove on the panel body, and provides a protruding rib and a stop groove on the limiting groove. The protruding rib and the stop groove are used to fix the panel rubber ring installed in the limiting groove, so as to ensure that the panel rubber ring does not come out in the limiting groove.

This application connects the positive electrode copper busbar 5 and the fuse copper busbar 7 to the panel body 1 by insert injection molding. The insert injection molding method replaces the existing fixing method of fixing to the panel body by insert nuts. The insert injection molding method does not require repeated tightening of bolts towards the insert nuts to fix the copper busbar to the panel body, which shortens the assembly time and improves the assembly efficiency. It also transfers the force of the copper busbar inside the battery pack to the panel shell, enhances the overall strength of the connector, and saves assembly time. This solves the technical problem of long assembly time in the existing fixing method of fixing the copper busbar to the panel body by insert nuts on the integrated panel.

When the panel body 1 is provided with two positive terminal connections 2 and two negative terminal connections 3, the two high-voltage positive terminals, two high-voltage negative terminals, and the fuse assembly 4 on the panel body 1 are integrated into a single structure. When the panel body 1 is provided with two negative electrode connection terminals 3, the negative electrode copper busbar 6 is a Y-shaped structure formed by riveting two copper busbars together. The two copper busbars are riveted together and then assembled onto the panel body 1 and connected to the two negative electrode connection terminals 3 respectively, realizing the parallel connection of two high-voltage negative electrodes.

The positive and negative shield 11 is fitted over the outer side of the shielding insulator 12. The inner shielding ring 13 and the outer shielding ring 14 are pressed onto the wires and then inserted into the shielding insulator 12, so that the shielding ring 14 contacts the spring contacts of the positive and negative shield 11 (6 contact points). The sealing body 15 and the gasket 16 are placed side-by-side inside the tail cap 9. The base housing 8 is integrally connected to the panel body 1. The base housing 8 contains an opening, and the terminal 10 is located within the opening. A top cap 27 is connected to the base housing 8 by screws, sealing the opening.

[0043] Example 4, based on Example 3, provides an integrated panel, such as... Figure 3 and Figure 4 As shown, the base housing 8 and the tail cover 9 are threaded together; the tail cover 9 is a gland head. The threaded connection between the base housing 8 and the tail cover 9 improves the ease of installation and removal of the base housing 8 and the tail cover 9. The tail cover 9 is a gland head because gland heads have a compact structure and high tensile strength.

[0044] Example 5, based on Example 4, provides an integrated panel, such as...

The fuse assembly 4 includes a handle housing 18 adapted to the fixed cavity. A fuse 19 is housed within the handle housing 18. Both ends of the fuse 19 are connected to socket contacts 21. One socket contact 21 of the fuse 19 is inserted into the positive copper busbar 5, and the other socket contact 21 of the fuse 19 is inserted into the fuse copper busbar 7. The fuse 19 is designed to quickly cut off the circuit between the positive copper busbar 5 and the fuse copper busbar 7 when a short circuit causes a sharp increase in current, preventing equipment overload or burnout. The handle housing 18 is designed to protect the fuse 19. The handle housing 18 is inserted into the panel body 1 and then secured with bolts, making the overall structure of the handle housing 18 and the panel body 1 more robust and able to better withstand the forces generated during product vibration and impact, thus improving safety performance.

[0047] The bottom of the fuse assembly 4 is provided with a socket anti-finger cover 28, which is located in the fixed cavity. The socket anti-finger cover 28 can not only realize the anti-finger function of the pin of the fuse assembly 4, but also play a guiding role when the pin is inserted into the socket, reducing the insertion force and facilitating insertion.

[0048] Example 7, based on Example 6, provides an integrated panel, such as... Figure 6 and Figure 7As shown, the fuse 19 has a cover plate 20 at its bottom, which is connected to the handle housing 18.

The sealing ring 22 further ensures the sealing performance after the handle housing 18 and the panel body 1 are assembled.

[0050] Example 9, based on Example 7 or 8, provides an integrated panel, such as... Figure 2 , Figure 3 , Figure 11 , Figure 12 and Figure 17 As shown, a panel rubber ring 23 is provided on the bottom surface of the panel body 1. The panel rubber ring 23 is provided to ensure the sealing performance of the panel body 1 after assembly.

The panel rubber ring 23 is provided with a mounting platform 24. The limiting groove is provided with a protruding rib 25 and a stop groove 26. The mounting platform 24 and the stop groove 26 are engaged, and the panel rubber ring 23 and the protruding rib 25 are interference-fitted. The stop groove 26 is connected to the limiting groove, and the protruding rib 25 is located in the limiting groove. When the mounting platform 24 and the stop groove 26 are engaged, and the panel rubber ring 23 and the protruding rib 25 are interference-fitted, the panel rubber ring 23 is more stably restricted in the limiting groove, ensuring the stability of the position of the panel rubber ring 23.

[0052] A sealing area 30 is integrally connected to the panel rubber ring 23. The sealing area 30 is disposed on the panel body 1 and surrounds the shielding spring 17 to seal and protect the shielding spring 17. This application achieves the goal of sealing the panel body 1 after assembly and simultaneously sealing and protecting the shielding spring 17.

[0053] In Example 10, two copper busbars are first riveted together to form a negative copper busbar 6, while a positive copper busbar 5 and a fuse copper busbar 7 are stamped. Then, the positive copper busbar 5 and the fuse copper busbar 7 are embedded into the mold of the panel body 1, and then the panel body 1 is formed by injection molding. Then, the negative copper busbar 6, the panel rubber ring 23 and the shielding spring 17 are installed on the panel body 1 to form the panel body 1 of this application. The fuse 19 and cover plate 20 are sequentially installed onto the handle housing 18. Then, the plug contact 21 is connected to both ends of the fuse 19. The sealing ring 22 is installed on the handle housing 18 to form the fuse assembly 4 of this application. A base housing 8 is integrally formed on the panel body 1 formed by injection molding. Terminals 10 are installed inside the base housing 8. Positive and negative shields 11, shielding insulators 12, inner shielding rings 13, outer shielding rings 14, sealing wires 15, and gaskets 16 are sequentially installed along the end of the base housing 8. The positive and negative shields 11 are sleeved on the outside of the shielding insulators 12. The inner shielding rings 13 and outer shielding rings 14 are pressed onto the wires and then inserted into the shielding insulators 12, so that the shielding rings 14 contact the springs of the positive and negative shields 11 (6 contact points). The sealing wires 15 and gaskets 16 are placed side by side in the tail cover 9. The end of the wire is connected to the terminal 10 to form the positive connection terminal 2 or the negative connection terminal 3 of this application. After the positive connection terminal 2 and the negative connection terminal 3 are assembled, the positive and negative shields 11 on the positive connection terminal 2 and the negative connection terminal 3 are in contact with the shielding springs 17 on the panel body 1 to form a shielding circuit. Then, the fuse assembly 4 is installed in the fixed cavity on the panel body 1. The fixed cavity on the panel body 1 contains the socket anti-touch cover 28. After the fuse assembly 4 is installed in place, the sealing ring 22 is adapted to the panel body 1 around the fixed cavity. At this time, the bottom of the cover plate 20 on the fuse assembly 4 abuts against the socket anti-touch cover 28.
