Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a power battery pack. Background Technology

[0002] The power battery pack is a key component of a vehicle. Current power battery packs are assembled using a modular approach, with the battery housing constructed from sheet metal through bending, welding, or stamping. Multiple battery modules are then housed within this sheet metal housing to form the power battery pack. However, using a sheet metal housing to support multiple battery modules presents the following problems:

[0003] (1) When a battery cell in the battery module is abnormal and needs to be repaired and replaced, the entire battery module needs to be removed. Since the entire battery module is bonded to the bottom of the box with structural adhesive, the entire power battery pack also needs to be replaced, which greatly reduces the efficiency of the replacement work.

[0004] (2) The complex internal circuitry of the enclosure results in messy wiring harnesses inside the power battery pack, requiring corresponding wiring and winding steps inside the power battery pack, which complicates the operation and increases the difficulty of installation.

[0005] Therefore, there is an urgent need for a power battery pack to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a power battery pack that avoids complicated steps such as wiring and winding, improves the efficiency of power battery pack installation and disassembly, and has a simple structure.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A power battery pack, comprising:

[0009] A battery module, comprising a plurality of battery cells arranged in sequence, each battery cell having an electrode terminal;

[0010] The mounting mechanism includes a base and multiple electrode connectors, wherein the multiple electrode connectors are spaced apart on the base, and each electrode terminal on each battery cell can make contact with the corresponding electrode connector for electrical connection; and

[0011] Multiple support mechanisms are spaced apart on the base. Each support mechanism includes a mounting component, a driving component, and a support frame. The mounting component is disposed on the base, and the driving component is disposed on the mounting component. The support frame supports the battery cell. The output end of the driving component is connected to the support frame. The driving component can drive the support frame to move relative to the mounting component, so that the electrode of the battery cell supported by the support frame contacts or separates from the corresponding electrode connector. The driving component can also drive the support frame to rotate upward relative to the mounting component while supporting the battery cell.

[0012] As an optional solution, the drive assembly includes a first linear drive, a second linear drive, and a transmission component. The first linear drive and the second linear drive are both disposed on the mounting assembly. The first linear drive and the second linear drive are arranged at intervals relative to each other along the moving direction of the support frame. Both the first linear drive and the second linear drive are connected to the support frame through the transmission component.

[0013] The drive assembly has a first drive mode and a second drive mode. When the drive assembly is in the first drive mode, the first linear drive member and the second linear drive member drive the transmission member to move in the same direction, so that the transmission member drives the support frame to move. When the drive assembly is in the second drive mode, one of the first linear drive member and the second linear drive member stops driving, and the other one drives the transmission member to move closer to the one that stops driving, so that the transmission member drives the support frame to flip upward.

[0014] As an optional solution, the transmission component includes:

[0015] The first connecting block is connected to the output end of the first linear drive unit;

[0016] The second connecting block is connected to the output end of the second linear drive unit;

[0017] A transmission connecting rod, the first end of which is rotatably connected to the first connecting block; and

[0018] The transmission block has a first end fixedly connected to the bottom of the support frame, a second end rotatably connected to the second end of the transmission connecting rod, and a third end rotatably connected to the second connecting block.

[0019] As an optional solution, the driving component further includes:

[0020] A guide rod is fixedly connected to the mounting assembly and extends along the moving direction of the support frame. Both the first connecting block and the second connecting block are slidably sleeved on the guide rod.

[0021] As an optional solution, the support frame includes a vertically connected support base plate and an abutment side plate. The support base plate supports the battery cell and is connected to the output end of the drive assembly. The abutment side plate abuts against the side wall of the battery cell.

[0022] As an optional solution, the power battery pack further includes a buffer mechanism, which includes:

[0023] A buffer substrate, wherein the buffer substrate is detachably mounted to the base; and

[0024] Multiple buffer protective frames are spaced apart on the buffer substrate, and each battery cell is surrounded by one of the buffer protective frames.

[0025] As an optional solution, the battery connector includes a battery mounting plate, a battery carrier plate, and an elastic element. The battery mounting plate is elastically connected to the base through the elastic element. The battery carrier plate is provided on the battery mounting plate, and a conductive sheet is provided on the battery carrier plate. The conductive sheet makes contact with the electrode of the corresponding battery cell.

[0026] The buffer protection frame includes a support bar and a buffer frame. The support bar is disposed on the buffer base plate, and the buffer frame is slidably disposed on the support bar. The buffer frame surrounds the outer periphery of the battery cell, and the buffer frame can move relative to the support bar towards the battery cell connector under the action of external force and abut against the battery cell support plate to push the battery cell mounting plate away from the battery cell.

[0027] As an optional solution, the buffer frame includes:

[0028] A buffer frame, which is slidably connected to the support bar;

[0029] A protective strip is fixedly connected to the buffer frame. The protective strip surrounds the outer perimeter of the battery cell and can abut against the battery cell support plate.

[0030] As an optional feature, the buffer frame further includes:

[0031] A buffer strip is attached to the buffer frame.

[0032] As an optional solution, the buffer protection frame also includes:

[0033] A limiting member is disposed on the support bar and is capable of abutting against the buffer frame to limit the extreme position of the buffer frame relative to the support bar in the direction closer to the electro-sheet connector.

[0034] The beneficial effects of this utility model are:

[0035] This utility model provides a power battery pack. By arranging multiple electrode connectors at intervals on a base, the electrode terminals of each battery cell in the battery module can contact and conduct with the corresponding electrode connector, thus achieving conductivity between the individual battery cells. This avoids complex steps such as wiring and winding, resulting in a simple structure and convenient operation. Furthermore, when replacing a battery cell in the battery module, the drive assembly moves the support frame relative to the mounting assembly, separating the electrode terminals of the battery cell supported by the support frame from the corresponding electrode connectors, thereby achieving a power-off operation for battery cell replacement. Then, the drive assembly drives the support frame to flip the battery cell upwards relative to the mounting assembly, flipping the de-energized battery cell out of the battery module for easy removal. When installing a battery cell, the drive assembly first drives the support frame to flip and reset relative to the mounting assembly, then drives the support frame to move and reset relative to the mounting assembly, ensuring that the electrode terminals of the battery cell supported by the support frame contact and conduct with the corresponding electrode connectors. This greatly improves the efficiency of battery cell installation and removal. Attached Figure Description

[0048] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0052] like Figures 1-3 As shown, this embodiment provides a power battery pack, which includes a battery module 1, a mounting mechanism 2, and multiple supporting mechanisms 3. The battery module 1 includes multiple battery cells 11 arranged sequentially, each battery cell 11 having a terminal 111. The mounting mechanism 2 includes a base 21 and multiple electrode connectors 22, which are spaced apart on the base 21. Each battery cell 11's terminal 111 can contact and conduct electricity with its corresponding electrode connector 22. The multiple supporting mechanisms 3 are spaced apart on the base 21, each supporting mechanism 3... The assembly includes a mounting component 31, a drive component 32, and a support frame 33. The mounting component 31 is disposed on the base 21, the drive component 32 is disposed on the mounting component 31, and the support frame 33 supports the battery cell 11. The output end of the drive component 32 is connected to the support frame 33. The drive component 32 can drive the support frame 33 to move relative to the mounting component 31, so that the electrode 111 of the battery cell 11 supported by the support frame 33 can contact and conduct or separate from the corresponding electrode connector 22. The drive component 32 can also drive the support frame 33 to rotate the battery cell 11 upward relative to the mounting component 31.

[0053] The power battery pack provided in this embodiment, by arranging multiple electrode connectors 22 at intervals on the base 21, enables the electrode terminals 111 on each battery cell 11 in the battery module 1 to contact and conduct with the corresponding electrode connector 22, thereby realizing the conduction operation of each battery cell 11, avoiding complex steps such as wiring and winding, making the structure simple and the operation convenient. Furthermore, when it is necessary to replace the battery cell 11 in the battery module 1, the drive assembly 32 drives the support frame 33 to move relative to the mounting assembly 31, so that the electrode 111 of the battery cell 11 supported by the support frame 33 is separated from the corresponding electrode connector 22, thereby realizing the power-off operation of replacing the battery cell 11. Then, the drive assembly 32 drives the support frame 33 to flip the battery cell 11 upward relative to the mounting assembly 31, thereby flipping the power-off battery cell 11 out of the battery module 1, so that the power-off battery cell 11 can be taken out. When it is necessary to install the battery cell 11, the drive assembly 32 first drives the support frame 33 to flip the battery cell 11 relative to the mounting assembly 31 back to its original position, and then the drive assembly 32 drives the support frame 33 to move and reset relative to the mounting assembly 31, so that the electrode 111 of the battery cell 11 supported by the support frame 33 can make contact and conduction with the corresponding electrode connector 22, which greatly improves the work efficiency of installing and removing the battery cell 11.

[0054] It should be noted that, in this embodiment, the multiple battery cells 11 in the battery module 1 are arranged sequentially along the left-right direction in the figure. In this embodiment, the drive component 32 can drive the support frame 33 to move relative to the mounting component 31 along the front-back direction in the figure.

[0055] In this embodiment, as Figure 1 and Figure 2 As shown, the base 21 includes a base body 211, a front connector 212, and a rear connector 213. The front connector 212 and the rear connector 213 are arranged at intervals in the front-to-back direction. Both the front connector 212 and the rear connector 213 are fixedly mounted on the base body 211, and the front connector 212 is located in front of the rear connector 213. The front connector 212 is provided with a plurality of electrical connectors 22 arranged at intervals in the left-to-right direction. A plurality of bearing mechanisms 3 are arranged sequentially in the left-to-right direction, and each bearing mechanism 3 is disposed between the front connector 212 and the rear connector 213. Specifically, in this embodiment, the mounting assembly 31 is fixedly connected between the front connector 212 and the rear connector 213. When the drive assembly 32 drives the support frame 33 to move backward relative to the mounting assembly 31, the electrode 111 of the battery cell 11 supported by the support frame 33 separates from the corresponding electrode connector 22. When the drive assembly 32 drives the support frame 33 to move forward relative to the mounting assembly 31, the electrode 111 of the battery cell 11 supported by the support frame 33 contacts and conducts electricity with the corresponding electrode connector 22.

[0056] Optionally, in this embodiment, as Figure 1 and Figure 2 As shown, the front connector 212 has multiple wiring slots 2121 spaced apart along the left and right directions. The wiring slots 2121 serve as external ports for the circuit and can be assembled with wiring on the vehicle body.

[0057] In this embodiment, as Figure 3 As shown, the drive assembly 32 includes a first linear drive member 321, a second linear drive member 322, and a transmission member 323. Both the first linear drive member 321 and the second linear drive member 322 are mounted on the mounting assembly 31. The first linear drive member 321 and the second linear drive member 322 are arranged at intervals relative to each other along the moving direction (front-back direction in the figure) of the support frame 33. Both the first linear drive member 321 and the second linear drive member 322 are connected to the support frame 33 via the transmission member 323. The drive assembly 32 has a first drive mode and a second drive mode. When the drive assembly 32 is in the first drive mode, the first linear drive member 321 and the second linear drive member 322 drive the transmission member 323 to move in the same direction, so that the transmission member 323 drives the support frame 33 to move. When the drive assembly 32 is in the second drive mode, one of the first linear drive member 321 and the second linear drive member 322 stops driving, and the other drives the transmission member 323 to move closer to the stopped drive member, so that the transmission member 323 drives the support frame 33 to flip upwards. The structural design of the drive assembly 32 ensures that it has two different drive modes, thereby meeting the drive requirements of the support frame 33. Optionally, in this embodiment, both the first linear drive member 321 and the second linear drive member 322 are electric telescopic rods; in other embodiments, the first linear drive member 321 and the second linear drive member 322 can also be linear cylinders.

[0058] Optionally, in this embodiment, when it is necessary to replace the battery cell 11 in the battery module 1, the drive assembly 32 is first put into the first drive mode, so that the first linear drive member 321 extends backward and the second linear drive member 322 retracts backward. At this time, the first linear drive member 321 and the second linear drive member 322 simultaneously drive the transmission member 323 to move backward, so that the transmission member 323 drives the support frame 33 to separate the electrode 111 of the battery cell 11 from the corresponding electrode connector 22, thereby realizing the power-off operation of replacing the battery cell 11. Then, the drive assembly 32 is put into the second drive mode, so that the first linear drive member 321 stops driving and the second linear drive member 322 extends forward, so that the second linear drive member 322 drives the transmission member 323 forward. At this time, the front end of the transmission member 323 cannot move, and the transmission member 323 can drive the support frame 33 to rotate the battery cell 11 upward and backward. When the support frame 33 needs to flip and reset the supported battery cell 11, the first linear drive 321 extends backward, and the second linear drive 322 remains stationary. When the flipped and reset battery cell 11 needs to be moved and reset, the first linear drive 321 retracts forward, and the second linear drive 322 extends forward simultaneously.

[0059] Optionally, in this embodiment, as Figure 3 As shown, the transmission component 323 includes a first connecting block 3231, a second connecting block 3232, a transmission connecting rod 3233, and a transmission block 3234. The first connecting block 3231 is connected to the output end of the first linear drive component 321, the second connecting block 3232 is connected to the output end of the second linear drive component 322, the first end of the transmission connecting rod 3233 is rotatably connected to the first connecting block 3231, the first end of the transmission block 3234 is fixedly connected to the bottom of the support frame 33, the second end of the transmission block 3234 is rotatably connected to the second end of the transmission connecting rod 3233, and the third end of the transmission block 3234 is rotatably connected to the second connecting block 3232. When the first linear drive member 321 stops driving and the second linear drive member 322 extends forward, the first connecting block 3231 remains stationary while the second connecting block 3232 moves forward. This causes the transmission connecting rod 3233 and the transmission block 3234 to rotate accordingly, resulting in the transmission connecting rod 3233 and the transmission block 3234 jointly pulling the support frame 33 upward and rearward. The structural design of the transmission member 323 simplifies its structure and ensures the reliability of its transmission operation.

[0060] Optionally, in this embodiment, as Figure 3As shown, the drive assembly 32 also includes a guide rod 324, which is fixedly connected to the mounting assembly 31. The guide rod 324 extends along the moving direction (front-back direction in the figure) of the support frame 33. Both the first connecting block 3231 and the second connecting block 3232 are slidably sleeved on the guide rod 324. By setting the guide rod 324, the movement of the first connecting block 3231 and the second connecting block 3232 in the front-back direction can be guided, thereby ensuring the reliability of the transmission component 323. In addition, the use of the guide rod 324 for guidance simplifies the structure.

[0061] In this embodiment, as Figure 3 As shown, the support frame 33 includes a vertically connected support base plate 331 and an abutment side plate 332. The support base plate 331 supports the battery cell 11, and its bottom is fixedly connected to the first end of the transmission block 3234. The abutment side plate 332 abuts against the side wall of the battery cell 11. The structural design of the support frame 33 effectively ensures the stability and reliability of supporting the battery cell 11. Specifically, in this embodiment, the abutment side plate 332 abuts against the rear side wall of the battery cell 11.

[0062] In this embodiment, as Figure 4 and Figure 5 As shown, the power battery pack also includes a buffer mechanism 4, which includes a buffer base plate 41 and multiple buffer protective frames 42. The buffer base plate 41 is detachably mounted on the base 21, and the multiple buffer protective frames 42 are spaced apart on the buffer base plate 41. Each battery cell 11 is surrounded by a buffer protective frame 42. By setting the buffer mechanism 4, each battery cell 11 is surrounded by a buffer protective frame 42, which avoids squeezing damage to the battery cell 11 under the action of external force impact, and provides an effective buffer protection effect for the battery cell 11 when it is impacted, thereby improving the safety of the battery module 1. It should be noted that in this embodiment, the multiple buffer protective frames 42 are spaced apart on the buffer base plate 41 in the left-right direction.

[0063] In addition, it should be noted that when it is necessary to replace the battery cell 11 in the battery module 1, the buffer substrate 41 is removed from the base 21, and then the support frame 33 supports the replaced battery cell 11 and moves and flips accordingly.

[0064] In this embodiment, as Figure 4 and Figure 5 As shown, the buffer mechanism 4 also includes a connecting bolt 43, and the buffer base plate 41 is detachably fixed to the wiring back seat 213 on the base 21 by the connecting bolt 43. The above configuration makes the installation and removal of the buffer mechanism 4 on the wiring back seat 213 more convenient and the structure simple.

[0065] Optionally, in this embodiment, as Figure 6 and Figure 7 As shown, the battery cell connector 22 includes a battery cell mounting plate 221, a battery cell support plate 222, and an elastic element 223. The battery cell mounting plate 221 is elastically connected to the base 21 through the elastic element 223. The battery cell support plate 222 is provided on the battery cell mounting plate 221, and a conductive battery cell 2221 is provided on the battery cell support plate 222. The conductive battery cell 2221 contacts and conducts with the electrode 111 on the corresponding battery cell 11. The buffer protection frame 42 includes a support bar 421 and a buffer frame 422. The support bar 421 is provided on the buffer base plate 41, and the buffer frame 422 is slidably provided on the support bar 421. The buffer frame 422 surrounds the outer periphery of the battery cell 11, and under the action of external force, the buffer frame 422 can move relative to the support bar 421 toward the direction closer to the battery cell connector 22 (i.e., forward) and abut against the battery cell support plate 222 to push the battery cell mounting plate 221 toward the direction away from the battery cell 11. The above configuration allows the buffer frame 422 to move forward relative to the support bar 421 when impacted by an external force. This pushes the electrode mounting plate 221 away from the battery cell 11, separating the conductive electrode 2221 from the corresponding electrode terminal 111 on the battery cell 11. This disconnects the battery cell 11 from power, preventing explosions or fires that could occur if the battery cell 11 remains conductive during the impact, thus improving the safety of the battery module 1. After the impact force disappears, the electrode mounting plate 221 resets under the elastic force of the elastic element 223, and the electrode support plate 222 pushes the buffer frame 422 to slide back to its original position relative to the support bar 421, ensuring that the conductive electrode 2221 re-establishes contact with the electrode terminal 111 on the corresponding battery cell 11. Optionally, in this embodiment, the elastic element 223 can be a spring, with its first end connected to the electrode mounting plate 221 and its second end connected to the wiring front seat 212 of the base 21.

[0066] Optionally, such as Figure 7 As shown, the buffer frame 422 includes a buffer frame 4221 and a protective strip 4222. The buffer frame 4221 is slidably connected to the support strip 421, and the protective strip 4222 is fixedly connected to the buffer frame 4221. The protective strip 4222 surrounds the outer periphery of the battery cell 11 and can abut against the battery cell support plate 222. By designing the buffer frame 422 into a structure of buffer frame 4221 and protective strip 4222, not only is the protection effect on the battery cell 11 guaranteed, but also the buffering effect of the entire buffer frame 422 is guaranteed.

[0067] Optionally, in this embodiment, the protective strip 4222 is L-shaped and is positioned on the top and front of the corresponding battery cell 11. The buffer frame 4221 is located at the rear of the battery cell 11, effectively ensuring the protection of the battery cell 11 in all directions.

[0068] Optionally, in this embodiment, as Figure 7 As shown, the buffer frame 422 also includes a buffer strip 4223, which is connected inside the buffer frame 4221. By connecting the buffer strip 4223 within the inner cavity of the buffer frame 4221, the buffering and protective effect of the buffer frame 422 is further ensured. Optionally, in this embodiment, the buffer strip 4223 can be made of rubber to ensure the overall buffering effect of the buffer frame 422.

[0069] In this embodiment, as Figure 7 As shown, the buffer protective frame 42 also includes a limiting member 423, which is disposed on the support bar 421. The limiting member 423 can abut against the buffer frame 422 to limit the extreme position of the buffer frame 422 relative to the support bar 421 in the direction closer to the electro-plate connector 22. By setting the limiting member 423, the protective bar 4222 in the buffer frame 422 is prevented from excessively pressing forward against the electro-plate connector 22. Optionally, in this embodiment, the limiting member 423 can be designed as an elastic limiting member, which not only ensures the buffering effect of the buffer protective frame 42, but also facilitates the sliding reset of the buffer frame 422. Specifically, in this embodiment, the limiting member 423 can abut against the front side of the buffer frame 4221.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
