A battery box assembly and a battery

Abstract

The application relates to a battery box assembly and a battery. The battery comprises the battery box assembly and a battery cell in the battery box assembly. The battery box assembly comprises a box body and an integrated connector. The battery further comprises a mounting frame and a box body threading channel. The mounting frame is integrally formed with the box body or mounted on the box body. The box body threading channel is located on the box body. The integrated connector is detachably connected to the mounting frame in the up-down direction and located outside the box body. The conductor for connecting the integrated connector and the battery cell in the box body can pass in and out of the box body through the box body threading channel. When the integrated connector is detached from the battery, the integrated connector can be directly and independently detached outside the box body without detaching the box body, and the number of detachment steps is reduced. When the battery is installed in a relatively compact mounting space in a vehicle, the space outside the battery in the up-down direction is relatively sufficient, the operation space for detaching the integrated connector is relatively large, and the detachment is convenient.

Description

Technical Field

[0001] This invention relates to a battery box assembly and a battery. Background Technology

[0002] With increasing environmental awareness, new energy electric vehicles are gradually becoming an important choice for people's travel. The battery is the main power source for new energy electric vehicles. A battery consists of a casing and battery cells located inside the casing. Multiple cells are connected in series and parallel, and then electrically connected to the vehicle body via connectors. Connectors include: a positive high-voltage connector and a negative high-voltage connector for electrical connection to the battery; a low-voltage input connector and a low-voltage output connector for detecting battery parameters such as temperature and voltage; and a heating input connector and a heating output connector for heating. In existing technologies, various connectors can be integrated into one place, forming an integrated connector. Using integrated connectors for batteries is beneficial to achieving battery weight reduction and increasing battery energy density to some extent.

[0003] In existing technologies, integrated connectors are generally installed on the front facade of the enclosure, with their connection structure located inside the enclosure and installed in the front-to-back direction. When replacement or maintenance requires disassembling the integrated connector, it cannot be removed independently from the outside of the enclosure; the enclosure must be disassembled to remove the connector, making disassembly cumbersome. Furthermore, given the current trend towards lightweighting and integration in new energy electric vehicles, the energy density requirements for automotive batteries are increasing, and the battery installation space is gradually decreasing. Additionally, new energy vehicles often have protective beams around the battery for circumferential protection, resulting in a narrow space in front of the enclosure. Disassembling the integrated connector requires front-to-back operation, limiting the operator's working space and impacting efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a battery box assembly that can solve the problems of cumbersome disassembly of the integrated connector on the battery box in the prior art, and the inconvenience of disassembling the integrated connector when the battery is located in a relatively compact installation space in the vehicle body.

[0005] In addition, the present invention aims to provide a battery that can solve the problems of troublesome disassembly of integrated connectors on batteries in the prior art, and the inconvenience of disassembling integrated connectors when the battery is installed in a relatively compact installation space in the vehicle body.

[0006] The battery box assembly of the present invention adopts the following technical solution:

[0007] Battery box assembly, including: box body;

[0008] Integrated connectors;

[0009] The battery also includes:

[0010] Mounting bracket, integrally formed with the cabinet, or mounted on the cabinet;

[0011] The cable routing channel is located on the enclosure.

[0012] The integrated connector is detachably connected to the mounting bracket in the vertical direction and is located on the outside of the housing;

[0013] Conductors used to connect the integrated connector and the battery cells in the enclosure can pass through the enclosure's wiring channels to enter and exit the enclosure.

[0014] Beneficial effects: The battery box assembly of the present invention integrates a connector that is detachably connected to the mounting bracket in the vertical direction and is located on the outside of the box. When performing the disassembly operation of the integrated connector, it can be directly and independently removed from the outside of the box without disassembling the box, and the disassembly steps are simple. When the battery box assembly is located in a relatively compact installation space inside the vehicle body, the space outside the box in the vertical direction is large, and there is sufficient space for disassembling the integrated connector, which is convenient for disassembly. This can solve the problems of troublesome disassembly of the integrated connector on the battery box in the prior art and the inconvenience of disassembly operation of the integrated connector when the battery is located in a relatively compact installation space inside the vehicle body.

[0015] Furthermore, the mounting bracket includes a housing, which comprises two pairs of opposing sidewalls and a bottom. The integrated connector is mounted on the bottom of the housing, and the interior of the housing can accommodate the conductors connecting the integrated connector and the battery cell. Containing the conductors inside the housing allows for a more concentrated and orderly distribution of the conductors, facilitating inspection and maintenance. Additionally, the housing provides some protection for the conductors it houses, reducing the adverse effects of the external environment on them.

[0016] Furthermore, the integrated connector is located on the outside of the housing. This location provides ample space for installation and removal, facilitating the assembly and disassembly of the integrated connector.

[0017] Furthermore, a sealing plate is detachably connected to the opening of the box, and the box or sealing plate has a channel for conductors to pass through. The sealing plate at the opening of the box can provide better protection for the conductors inside the box, preventing them from being exposed to the external environment.

[0018] Furthermore, the side wall of the box is provided with a mating structure that seals and connects with the wiring channel of the enclosure. The wiring channel is located on the side wall of the box and corresponds to the wiring channel. With the above-mentioned mating structure between the box and the enclosure, the conductor wiring distance is shorter and the conductor arrangement is more compact. When the conductor passes through the box and the enclosure, the portion not exposed to the external environment is all located inside the box and the enclosure, which can prevent the conductor from being damaged by the external environment.

[0019] Furthermore, the box opening faces upwards, with the integrated connector located on the lower side of the box. Since the box contains conductors, the upward-facing opening facilitates wiring operations for the integrated connector and conductors from the upper side of the box, and also facilitates inspection and maintenance of the conductors inside the box during later use.

[0020] Furthermore, a protective plate is provided on the outside of the integrated connector to protect it. The protective plate protects the integrated connector from water splashes when the vehicle is wading through water, preventing insulation failure caused by water splashes onto the integrated connector.

[0021] Furthermore, the protective plate is a bent plate, with one side connected to the housing and the other side connected to the enclosure, enclosing the integrated connector inside. The two external terminals of the integrated connector extend from both ends of the protective plate. The bent plate design simplifies the manufacturing process; it is simultaneously fixed to both the housing and the enclosure, resulting in a stable and robust connection structure; and by enclosing the integrated connector inside, with its two external terminals extending from both ends, the protective plate provides protection without hindering the connection of the connector's external terminals to the outside.

[0022] Furthermore, the external end of the integrated connector for connection to the outside is oriented in a direction parallel to the wall of the housing containing the integrated connector. With this structure, the operator can connect or disconnect the integrated connector from the outside in a direction parallel to the wall of the housing. There is ample space outside the housing in the direction parallel to the housing wall, providing a large operating space and facilitating the connection or disconnection of the integrated connector from the outside.

[0023] The battery of the present invention adopts the following technical solution:

[0024] A battery, including a battery housing assembly and battery cells located within the battery housing assembly;

[0025] The battery box assembly includes: a box body;

[0026] Integrated connectors;

[0027] The battery also includes:

[0028] Mounting bracket, integrally formed with the cabinet, or mounted on the cabinet;

[0029] The cable routing channel is located on the enclosure.

[0030] The integrated connector is detachably connected to the mounting bracket in the vertical direction and is located on the outside of the housing;

[0031] Conductors used to connect the integrated connector and the battery cells in the enclosure can pass through the enclosure's wiring channels to enter and exit the enclosure.

[0032] Beneficial effects: The battery of the present invention has an integrated connector that is detachably connected to the mounting bracket in the vertical direction and is located on the outside of the housing. When performing the integrated connector disassembly operation, the integrated connector can be directly and independently removed from the outside of the housing without disassembling the housing, and the disassembly steps are simple. When the battery is located in a relatively compact installation space inside the vehicle body, the space outside the housing in the vertical direction is large, and there is sufficient space for disassembling the integrated connector, which is convenient for disassembly. This can solve the problems of troublesome disassembly of the integrated connector on the battery in the prior art and the inconvenience of disassembling the integrated connector when the battery is installed in a relatively compact installation space inside the vehicle body.

[0033] Furthermore, the mounting bracket includes a housing, which comprises two pairs of opposing sidewalls and a bottom. The integrated connector is mounted on the bottom of the housing, and the interior of the housing can accommodate the conductors connecting the integrated connector and the battery cell. Containing the conductors inside the housing allows for a more concentrated and orderly distribution of the conductors, facilitating inspection and maintenance. Additionally, the housing provides some protection for the conductors it houses, reducing the adverse effects of the external environment on them.

[0034] Furthermore, the integrated connector is located on the outside of the housing. This location provides ample space for installation and removal, facilitating the assembly and disassembly of the integrated connector.

[0035] Furthermore, a sealing plate is detachably connected to the opening of the box, and the box or sealing plate has a channel for conductors to pass through. The sealing plate at the opening of the box can provide better protection for the conductors inside the box, preventing them from being exposed to the external environment.

[0036] Furthermore, the side wall of the box is provided with a mating structure that seals and connects with the wiring channel of the enclosure. The wiring channel is located on the side wall of the box and corresponds to the wiring channel. With the above-mentioned mating structure between the box and the enclosure, the conductor wiring distance is shorter and the conductor arrangement is more compact. When the conductor passes through the box and the enclosure, the portion not exposed to the external environment is all located inside the box and the enclosure, which can prevent the conductor from being damaged by the external environment.

[0037] Furthermore, the box opening faces upwards, with the integrated connector located on the lower side of the box. Since the box contains conductors, the upward-facing opening facilitates wiring operations for the integrated connector and conductors from the upper side of the box, and also facilitates inspection and maintenance of the conductors inside the box during later use.

[0038] Furthermore, a protective plate is provided on the outside of the integrated connector to protect it. The protective plate protects the integrated connector from water splashes when the vehicle is wading through water, preventing insulation failure caused by water splashes onto the integrated connector.

[0039] Furthermore, the protective plate is a bent plate, with one side connected to the housing and the other side connected to the enclosure, enclosing the integrated connector inside. The two external terminals of the integrated connector extend from both ends of the protective plate. The bent plate design simplifies the manufacturing process. The bent plate is simultaneously connected and fixed to both the housing and the enclosure, resulting in a stable and robust connection structure. By enclosing the integrated connector inside and allowing its two external terminals to extend from both ends of the protective plate, the protective plate provides protection for the integrated connector without hindering its external connection to the outside.

[0040] Furthermore, the external end of the integrated connector for connection to the outside is oriented in a direction parallel to the wall of the housing containing the integrated connector. With this structure, the operator can connect or disconnect the integrated connector from the outside in a direction parallel to the wall of the housing. There is ample space outside the housing in the direction parallel to the housing wall, providing a large operating space and facilitating the connection or disconnection of the integrated connector from the outside.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0047] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0048] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0049] Specific embodiment 1 of the battery of the present invention:

[0050] The battery of the present invention, such as Figures 1 to 3 As shown, the battery includes a battery box assembly and battery cells located within the battery box assembly. The battery box assembly includes a housing 1 and an integrated connector 3. The housing 1 includes an upper housing 11 located above and a lower housing 12 located below. The integrated connector 3 is located on the outside of the upper housing 11. Since a conductor connects the integrated connector 3 to the battery cells inside the housing 1, a wiring channel 13 is provided on the front surface of the upper housing 11 for the conductor to pass through and exit the upper housing 11.

[0051] A mounting bracket 2 is fixedly installed on the front facade of the upper housing 11. The integrated connector 3 is detachably connected to the mounting bracket 2 and remains relatively fixed to the upper housing 11. The mounting bracket 2 includes a housing 21, which includes two pairs of opposing side walls and a bottom. The opening of the housing 21 faces upward. The integrated connector 3 is installed on the lower side of the housing 21 and is detachably connected to the bottom of the housing 21 along the vertical direction by fasteners. A through hole is provided on the bottom of the housing 21, allowing the terminals of the integrated connector 3 for connection with conductors to extend from bottom to top into the housing. The interior of the housing 21 can accommodate conductors. A sealing plate 4 is detachably connected to the opening of the housing 21, which provides some protection for the conductors inside the housing 21. The four side walls of the box 21 are provided with screw holes extending in the vertical direction near the opening of the box. The sealing plate 4 is provided with corresponding through holes. The sealing plate 4 is detachably connected to the box 21 by screws being inserted into the through holes and screw holes in sequence. The screw connection is convenient to disassemble and secure.

[0052] The side wall of the housing 21 is provided with a docking structure 22 for fixing the mounting bracket 2 to the front surface of the upper housing 11. The upper housing 11 has a connecting hole at the housing wiring channel 13, and the housing 21 has a corresponding hole at the docking structure 22. After aligning the connecting hole with the hole on the docking structure 22, the connection is secured with bolts, and a sealant is applied to the joint between the docking structure 22 and the upper housing 11 to form a sealed connection. To allow the conductor to enter the upper housing 11 from the housing 21 or vice versa, the side wall of the housing 21 with the docking structure 22 has a housing channel 23. The housing channel 23 corresponds to the housing wiring channel 13 when the docking structure 22 is sealed to the upper housing 11.

[0053] The integrated connector 3 has a protective plate 5 on its outer side. The protective plate 5 is a bent plate, with one side of the bent plate connected to the housing 21 by bolts. The other side of the bent plate extends towards the housing 1 along the intersection of the two sides and is fixed to the lower base 12. The bent plate is connected to both the lower base 12 and the housing 21, providing a relatively stable connection. One side of the bent plate is located on the side of the integrated connector 3 facing away from the housing 11, and the other side is located on the lower side of the integrated connector 3. The bent plate, the bottom of the housing, and the housing 1 together enclose the integrated connector 3 internally. The two external ends of the integrated connector 3 extend from both ends of the protective plate 5. The protective plate 5 can be made by stamping, tearing, composite material molding, injection molding, or vacuum forming. It does not need to be too strong, and its main function is to prevent water from splashing onto the integrated connector 3 when the vehicle is wading through water.

[0054] After the integrated connector 3 is installed on the mounting bracket 2, it has a terminal at the middle of its length for connecting to the battery cells inside the housing. The terminal faces upward and passes through the perforation on the bottom of the housing 21 to facilitate wiring. The integrated connector 3 also has external terminals on both sides of its length for connecting to the outside of the battery, such as the vehicle body. These external terminals extend from both ends of the protective plate, facing a direction parallel to the front facade of the upper housing. When the battery is installed in a relatively compact space within the vehicle body, it is convenient for the operator to connect the external terminals to the vehicle body in a direction parallel to the front facade of the upper housing, resulting in a large operating space and high operating efficiency.

[0055] During battery assembly, the battery cells are first stacked and installed on the lower housing 12. Then, the upper housing 11 is installed on the lower housing 12 using bolts. After aligning the holes of the mating structure with the connecting holes on the upper housing 11, the mounting bracket 2 is fixed to the upper housing 11 using bolts. Subsequently, the integrated connector 3 is installed and fixed on the bottom of the housing 21 of the mounting bracket 2. Then, the protective plate 5 is installed using bolts, so that the protective plate 5 is fixedly connected to both the housing 21 and the lower housing 12. Afterward, the integrated connector 3 is connected to the battery cells in the housing using a conductor. Finally, the sealing plate 4 is installed at the opening of the housing to seal the opening.

[0056] When the battery of the present invention is installed in a relatively compact space within the vehicle body, the operator can install or remove the integrated connector from the outside of the front facade of the upper housing along the vertical direction. Since the space outside the front facade of the upper housing in the vertical direction is relatively large, there is sufficient space for installation and removal, making it convenient to install or remove the integrated connector. Furthermore, the integrated connector is fixed to the outside of the upper housing by a mounting bracket. When it is necessary to remove the integrated connector, it is only necessary to open the sealing plate at the top of the housing, disconnect the conductor from the integrated connector, and then the integrated connector can be removed directly without disassembling the upper housing and the lower housing. The integrated connector removal steps are few and the removal is relatively convenient.

[0057] Specific embodiment 2 of the battery of the present invention:

[0058] Unlike Embodiment 1, the mounting bracket includes a plate-like structure and a fixing structure, which are perpendicular to each other. The fixing structure is used to fix itself to the upper housing and mates with the wiring channel of the housing.

After the fixing structure is fixed to the upper housing, the plate-like structure is parallel to the horizontal plane. An integrated connector is installed on the lower side of the plate-like structure, and the plate-like structure also has through holes for the terminals of the integrated connector to pass through the plate-like structure from bottom to top. In addition, a box-like cover is provided on the outside of the plate-like structure.

The sealing plate is provided with a box-shaped cover, which is sealed to the sealing plate and the upper box, covering the conductor and the box wiring channel inside the box-shaped cover.

[0063] Specific embodiment 5 of the battery of the present invention:

[0064] Unlike Embodiment 1, the box opening faces downwards, the integrated connector is installed at the bottom of the box, and the integrated connector is located on the upper side of the box.

[0065] Specific embodiment 6 of the battery of the present invention:

[0066] Unlike Embodiment 1, a plate extending horizontally towards the front side of the upper housing is formed by punching and folding. The plate has through holes and mounting structures for installing integrated connectors, forming a mounting frame. A housing hole formed on the front side of the upper housing by punching and folding is located on the upper side of the plate, forming a wiring channel. The integrated connector is installed on the lower side of the mounting frame. The connector's terminals pass through the through holes in the mounting frame. The housing hole allows conductors to pass through and exit the upper housing. A sealing cover is also provided on the front side of the upper housing, sealingly connecting both the upper housing and the mounting frame. The sealing cover encloses the conductors and the housing hole within it.

[0067] Specific embodiment 7 of the battery of the present invention:

[0068] Unlike Embodiment 1, the protective plate is a long strip plate, which is installed on the housing and located on the side of the integrated connector facing away from the housing, providing protection only for the front side of the integrated connector.

[0069] The battery box assembly of the present invention is described in a specific embodiment. The battery box assembly in this embodiment has the same structure as the battery box assembly in any specific embodiment of the battery of the present invention, and will not be described again here.
