Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to housing structures, power batteries, and vehicles. Background Technology

[0002] The vehicle's power battery provides power to electrical components such as the motor controller, drive motor, lights, audio system, and air conditioning. To facilitate connection between the power battery and these components, connectors are typically provided to link the battery cells to the devices. Furthermore, the power battery is usually located at the bottom of the vehicle, making it susceptible to damage from impacts or significant shocks during driving.

[0003] In the prior art, a power battery includes a battery pack and a protective cover. The battery pack has multiple connection ports on one side, and the protective cover is located on the side of the battery pack to shield and protect these connection ports. The protective cover includes a base plate, a vertical plate, and an inclined plate. One side of the base plate is connected to the bottom side of the battery pack, and one side of the inclined plate is connected to the middle side of the battery pack. The vertical plate connects the base plate and the inclined plate to the side away from the battery pack. The base plate, vertical plate, and inclined plate form a protective frame, and the connection ports are located within the protective frame.

[0004] Thus, when the power battery is subjected to a collision or a large impact, the deformation of the protective cover will directly act on the terminal, thereby impacting and damaging the terminal and resulting in poor protection of the terminal. Utility Model Content

[0005] One objective of this invention is to provide a housing structure to address the problem of improving the protection of docking connectors. A second objective is to provide a power battery. A third objective is to provide a vehicle.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] In a first aspect, embodiments of this application provide a housing structure, which includes a housing body, a connector, and a protective structure. The housing body includes a support portion for carrying the battery cell and a connecting portion connected to the support portion. The connector is connected to the connecting portion, and a portion of the connector is located on the side of the connecting portion opposite to the support portion. The protective structure is connected to the side of the connecting portion opposite to the support portion and is located around the connector to protect the connector.

[0008] According to the aforementioned technical means, the connector is connected to the connecting part, and the connector portion is located on the side of the connecting part opposite to the supporting part, which facilitates the connection of the connector to other components. The protective structure is connected to the side of the connecting part opposite to the supporting part and is located around the connector. When the power battery is subjected to collision or impact, the protective structure will withstand the impact force, thus protecting the connector. Furthermore, if the protective structure deforms after withstanding the impact force, it will not directly impact the connector or its edge, thus minimizing damage to the connector and providing more effective protection, thereby extending the connector's service life.

[0009] In some embodiments, the protective structure includes a plurality of first protective members, which are spaced apart along a first direction, the first direction being perpendicular to the arrangement direction of the connecting portion and the bearing portion; a protective space is formed between any two adjacent first protective members; the connector includes a first connector, which is disposed in the protective space.

[0010] According to the above technical means, when the first protective component is deformed by collision or impact, it will only collide with the connector if it bends in the first direction toward the connector, while it will not collide with the connector if it deforms in other directions. This can reduce the probability of the connector being collided with and improve the protective effect on the connector.

[0011] In some embodiments, the number of first connectors is multiple, and at least one first connector is provided in a protective space.

[0012] Based on the above technical means, different first connectors can be protected separately. When one of the first connectors is severely impacted, multiple first protective components can absorb the impact force or shock force before the impact reaches other first connectors, thereby reducing the damage to other first connectors and minimizing the loss caused by the collision.

[0013] In some embodiments, the number of first connectors is multiple, and the first connectors are provided in portions of the multiple protected spaces.

[0014] According to the above technical means, when the collision location is the location corresponding to the protective space where the first connector is not installed, the first protective component at the collision location can absorb the impact force or shock force generated by the collision, thereby reducing the impact force or shock force when it is transmitted to the location of the first connector. At this time, the first protective component at the location of the first connector can absorb the impact force or shock force again, thereby maximizing the absorption of the impact force or shock force and improving the protection effect on the first connector.

[0015] In some embodiments, the protective structure further includes a plurality of second protective members, a portion of which is disposed on one side of a plurality of first protective members in a first direction, and another portion of which is disposed on the other side of a plurality of first protective members in the first direction.

[0016] According to the above technical means, when the power battery is subjected to an impact force or shock in the first direction, the second protective component can first withstand the impact force or shock to absorb it, and then the first protective component can absorb the impact force or shock again, thereby gradually weakening the impact force or shock to better protect the first connector.

[0017] In some embodiments, the lengths of the first protective member and the second protective member are not equal along the arrangement direction of the support portion and the connecting portion.

[0018] According to the above technical means, when the power battery is subjected to an impact force or shock in the direction of the arrangement of the bearing part and the connecting part, the longer of the first protective member and the second protective member will first bear the impact force or shock, thereby absorbing the impact force or shock. Then, the shorter of the first protective member and the second protective member can absorb the impact force or shock again, thereby gradually weakening the impact force or shock, so as to better protect the first connector.

[0019] In some embodiments, the connector further includes a second connector connected to one side of the second protective member in a second direction, the second direction being perpendicular to the first direction and perpendicular to the arrangement direction of the support portion and the connecting portion.

[0020] Based on the above technical means, the space occupied by the second connector in the first direction can be reduced, thereby allowing for a more reasonable arrangement of the positions of the first protective component, the second protective component, the first connector, and the second connector, so as to provide better protection for the first connector and the second connector.

[0021] In some embodiments, along the arrangement direction of the support portion and the connecting portion, the length of the first protective member is greater than the length of the portion of the first connector located on the side of the connecting portion opposite to the support portion, and is also greater than the length of the portion of the second connector located on the side of the connecting portion opposite to the support portion.

[0022] Based on the above technical means, when the power battery is impacted or subjected to shock, the first protective component can be guaranteed to withstand the impact force or shock force, thereby providing better protection for the first connector and the second connector.

[0023] In some embodiments, along the arrangement direction of the support portion and the connecting portion, the length of the second protective member is greater than the length of the portion of the first connector located on the side of the connecting portion opposite to the support portion, and is also greater than the length of the portion of the second connector located on the side of the connecting portion opposite to the support portion.

[0024] Based on the above technical means, when the power battery is impacted or subjected to shock, the second protective component can be guaranteed to withstand the impact force or shock force, thereby providing better protection for the first connector and the second connector.

[0025] In some embodiments, the protective structure includes one of a sheet metal structure, an aluminum alloy structure, and a composite material structure.

[0026] Based on the aforementioned technical means, sheet metal structures, aluminum alloy structures, and composite material structures all possess high structural strength. When the power battery is subjected to collision or impact, it can effectively absorb the impact force, thereby providing better protection for the connectors.

[0027] Secondly, embodiments of this application also provide a power battery, which includes a housing structure and a battery module as described in the first aspect, with the battery module disposed within the housing structure.

[0028] Since the power battery provided in this application includes the housing structure in the first aspect, it can solve the same technical problems as the housing structure described above and achieve the same technical effects, so it will not be described again here.

[0029] Thirdly, embodiments of this application also provide a vehicle that includes the power battery described in the second aspect above.

[0030] Since the vehicle provided in this application includes the power battery in the second aspect, it can solve the same technical problems as the power battery described above and achieve the same technical effects, so it will not be described again here. Attached Figure Description

[0044] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0045] Please see Figure 1 This application provides a vehicle 1000. The vehicle 1000 can be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, a gasoline vehicle, etc.

[0046] Vehicle 1000 includes a body 100, wheels 200, and a drive unit 300. Wheels 200 are connected to the underside of the body 100 and are used to roll on the ground, thereby enabling vehicle 1000 to move. The drive unit 300 is connected to the body 100 and to the wheels 200, and is used to drive the wheels 200 to rotate, thereby enabling the wheels 200 to roll on the ground. Exemplarily, the drive unit 300 may include a drive motor. The drive unit 300 may also include a drive motor and an engine. The drive unit 300 may also include a drive motor, an engine, and a generator. This application does not specifically limit this aspect.

[0047] The vehicle 1000 also includes a power battery 400, which is connected to the vehicle body 100 and the drive unit 300 to provide electrical power to the drive unit 300, enabling the drive unit 300 to drive the wheels 200 to rotate. Specifically, the power battery 400 can be connected to a drive motor to provide electrical power to the drive motor. The power battery 400 can also be connected to a generator to charge the power battery 400, ensuring that the power battery 400 has sufficient electrical power.

[0048] In some embodiments, please refer to Figure 2 The power battery 400 may include a housing structure 10 and a battery module. The battery module is located inside the housing structure 10 and is used to provide power to the drive device 300. The battery module includes multiple battery cells.

[0049] In some examples, the housing structure 10 has a receiving cavity 10A, within which the battery module is disposed. The number of receiving cavities 10A can be one or more. The number of battery modules can also be one or more. At least one battery module can be disposed within one receiving cavity 10A.

[0050] In some embodiments, please continue reading Figure 2 The housing structure 10 includes a housing body 1, which may include a support portion 11 for carrying batteries and a connecting portion 12 connected to the support portion 11. The support portion 11 has multiple receiving cavities 10A to support the battery modules within the receiving cavities 10A. The connecting portion 12 is used to house components that connect to the battery modules, such as copper busbars, battery management units, etc.

[0051] In some examples, the load-bearing portion 11 may include a plurality of first crossbeams 111 and a plurality of first longitudinal beams 112, the plurality of first crossbeams 111 being along a third direction (e.g., Figure 2 Multiple first longitudinal beams 112 are spaced apart in the first direction (e.g., Z-direction), and are arranged at intervals along the first direction (e.g., Z-direction). Figure 2 The beams are spaced apart in the direction X, with the first direction perpendicular to the second direction. Any one first crossbeam 111 is connected to multiple first longitudinal beams 112, and any one first longitudinal beam 112 is connected to multiple first crossbeams 111, so that the multiple first crossbeams 111 and multiple first longitudinal beams 112 are intersected to form the supporting part 11 of the housing body 1. The supporting part 11 has multiple receiving cavities 10A. This allows for easy division into multiple receiving cavities 10A by the multiple first crossbeams 111 and multiple first longitudinal beams 112, facilitating the installation of multiple battery modules within the housing body 1.

[0052] In other examples, the main body 1 of the housing may also be other structures capable of forming the receiving cavity 10A, such as a receiving cavity 10A surrounded by multiple plate-like structures. This application does not specifically limit this.

[0053] In some examples, the connecting portion 12 may include a second crossbeam 121 and a plurality of second longitudinal beams 122. The second crossbeam 121 is located on the third-direction side of the supporting portion 11, and the plurality of second longitudinal beams 122 are spaced apart along the first direction and are all connected between the second crossbeam 121 and the supporting portion 11. In this way, an accommodating space can also be formed between the second crossbeam 121 and the plurality of second longitudinal beams 122, which can facilitate the placement of components connecting to the battery module, such as copper busbars and battery management units, within the accommodating space, thereby facilitating the placement of components connecting to the battery module.

[0054] In other examples, the connecting part 12 may also be a plate-like structure, a block-like structure, or an irregular structure, etc., and this application does not make specific limitations in this regard.

[0055] In some embodiments, the main body 1 of the enclosure can be an aluminum alloy enclosure or a sheet metal enclosure. In this case, the multiple first crossbeams 111, multiple first longitudinal beams 112, second crossbeams 121 and multiple second longitudinal beams 122 can be connected by welding or by other methods such as screwing or snap-fitting.

[0056] In some other embodiments, the main body 1 of the box can also be integrally die-cast from composite materials, which can ensure the structural strength of the main body 1 of the box.

[0057] In some embodiments, please continue reading Figure 2 The housing structure 10 also includes connectors 2, which are used to connect the battery module and electrical equipment. Specifically, connectors 2 can be electrically connected to the battery module via copper busbars, and electrical equipment can be plugged into connectors 2 via connector cables with plug-in interfaces, thus achieving electrical connection between connectors 2 and electrical equipment, and consequently, electrical connection between the electrical equipment and the battery module. The electrical equipment can be a motor controller, drive motor, vehicle lights, audio system, air conditioner, etc.

[0058] Connector 2 is connected to connecting portion 12, and a portion of connector 2 is located on the side of connecting portion 12 opposite to the support portion 11. For example, connector 2 is connected to the second crossbeam 121, and a portion of connector 2 is located on the side of the second crossbeam 121 opposite to the support portion 11. This allows connector 2 to be connected from the side of connecting portion 12 opposite to the support portion 11, thus reducing space constraints and facilitating connection of connector 2 to electrical equipment.

[0059] In some examples, connector 2 may include a first connector 21. The number of first connectors 21 may be one or more. This application is illustrated by way of example with multiple first connectors 21. Having multiple first connectors 21 facilitates the electrical connection of multiple electrical devices to the battery module.

[0060] In some examples, multiple first connectors 21 can be arranged along a first direction, that is, along the extension direction of the second crossbeam 121. This makes better use of the space of the connecting part 12 and makes the arrangement of multiple first connectors 21 more reasonable.

[0061] For example, the first connector 21 includes a high-voltage connector and a low-voltage connector. The high-voltage connector is used to connect high-voltage components in electrical equipment, such as drive motors, motor controllers, etc. The low-voltage connector is used to connect low-voltage components in electrical equipment, such as vehicle lights, audio systems, etc.

[0062] In some instances, connector 2 may further include a second connector 22, which may be located on one side of multiple first connectors 21 in the first direction, or on multiple first connectors 21 in the second direction (e.g., ...). Figure 2 The second direction (Y) is shown on one side, wherein the second direction is perpendicular to the first direction and perpendicular to the third direction. For example, the second connector 22 can be a fast-charging connector. The fast-charging connector is used to connect to a charging station to facilitate charging of the power battery 400.

[0063] In some embodiments, please continue reading Figure 2 The housing structure 10 also includes a protective structure 3. The protective structure 3 is used to protect the connector 2. The protective structure 3 is connected to the side of the connecting portion 12 opposite to the supporting portion 11 and is located around the periphery of the connector 2. For example, the protective structure 3 is connected to the side of the second crossbeam 121 opposite to the supporting portion 11. For example, the protective structure 3 and the connecting portion 12 can be connected by screws, welding, snap-fit, or other methods.

[0064] The protective structure 3 is connected to the side of the connector 12 opposite to the bearing part 11 and is located on the periphery of the connector 2. When the power battery 400 is hit or impacted, the protective structure 3 will bear the impact force or shock force, thereby protecting the connector 2. If the protective structure 3 deforms after bearing the impact force or shock force, the protective structure 3 will not directly hit the connector 2, or will only hit the edge of the connector 2. In this way, the damage to the connector 2 is smaller, thereby providing more effective protection for the connector 2 and improving the service life of the connector 2.

[0065] In some embodiments, the protective structure 3 may include one of a sheet metal structure, an aluminum alloy structure, and a composite material structure. The composite material structure may be an aluminum-based composite material structure, a nickel-based composite material structure, etc., and this application does not specifically limit its application to this type.

[0066] Sheet metal structure, aluminum alloy structure and composite material structure all have high structural strength. When the power battery 400 is hit or impacted, it can absorb the impact force or shock force well, thus providing better protection for the connector 2.

[0067] In some embodiments, please refer to Figure 3 The protective structure 3 may include a plurality of first protective members 31. The plurality of first protective members 31 are spaced apart along a first direction, which is perpendicular to the arrangement direction of the connecting part 12 and the bearing part 11. For example, the first direction may be the arrangement direction of a plurality of first crossbeams 111.

[0068] A protective space 32 is formed between any two adjacent first protective components 31, and the first connector 21 is disposed in the protective space 32. In this way, when the first protective component 31 is deformed by collision or impact, it will only collide with the connector 2 if it bends in the first direction toward the connector 2, while it will not collide with the connector 2 if it deforms in other directions. This reduces the probability of the connector 2 being collided with and improves the protective effect on the connector 2.

[0069] Furthermore, since the first connector 21 is located within the protective space 32, when the power battery 400 is subjected to an impact force or shock in the first direction and an impact force or shock in the third direction, the first protective component 31 can absorb the impact force or shock, thereby protecting the first connector 21 from multiple directions and improving the protection effect.

[0070] In some examples, the first protective member 31 can be a columnar structure, a plate-like structure, a rod-like structure, a block-like structure, etc., and this application does not make specific limitations on it.

[0071] In some examples, along the arrangement direction of the support portion 11 and the connecting portion 12, i.e., in the third direction, the length of the first protective member 31 is greater than the length of the portion of the first connector 21 located on the side of the connecting portion 12 opposite to the support portion 11. In this way, when the power battery 400 is impacted or subjected to shock, the first protective member 31 can withstand the impact force or shock, thereby providing better protection for the first connector 21.

[0072] In some embodiments, please continue reading Figure 3 When there are multiple first connectors 21, at least one first connector 21 can be set in a protective space 32. In this way, different first connectors 21 can be protected separately. When the corresponding position of one first connector 21 is severely impacted, multiple first protective components 31 can absorb the impact force or shock force before the impact affects other first connectors 21, thereby reducing the damage to other first connectors 21 and reducing the loss caused by the collision.

[0073] In some other embodiments, when there are multiple first connectors 21, some of the multiple protective spaces 32 may also be provided with first connectors 21. That is, some protective spaces 32 are provided with first connectors 21, and one or more first connectors 21 may be provided in one protective space 32. Other protective spaces 32 are not provided with first connectors 21.

[0074] In this way, when the collision location is the location corresponding to the protective space 32 where the first connector 21 is not installed, the first protective member 31 at the collision location can absorb the impact force or shock force generated by the collision, thereby reducing the impact force or shock force when it is transmitted to the location of the first connector 21. At this time, the first protective member 31 at the location of the first connector 21 can absorb the impact force or shock force again, thereby maximizing the absorption of the impact force or shock force and improving the protection effect on the first connector 21.

[0075] In some embodiments, please continue reading Figure 3The protective structure 3 also includes a plurality of second protective members 33, some of which are disposed on one side of the plurality of first protective members 31 in the first direction, and other parts of the plurality of second protective members 33 are disposed on the other side of the plurality of first protective members 31 in the first direction.

[0076] In this way, when the power battery 400 is subjected to an impact force or shock in the first direction, the second protective component 33 can first withstand the impact force or shock to absorb it, and then the first protective component 31 can absorb the impact force or shock again, thereby gradually weakening the impact force or shock to better protect the first connector 21.

[0077] In some examples, the second protective member 33 can be a columnar structure, a plate-like structure, a rod-like structure, a block-like structure, etc., and this application does not make specific limitations on it.

[0078] In some embodiments, along the arrangement direction of the support portion 11 and the connecting portion 12, i.e., the third direction, the length of the first protective member 31 is not equal to the length of the second protective member 33. That is, along the third direction, the length of the first protective member 31 is greater than the length of the second protective member 33, or the length of the second protective member 33 is greater than the length of the first protective member 31.

[0079] In this way, when the power battery 400 is subjected to an upward impact force from a third party, the longer of the first protective member 31 and the second protective member 33 will first bear the impact force, thereby absorbing the impact force. Then, the shorter of the first protective member 31 and the second protective member 33 can absorb the impact force again, thereby gradually weakening the impact force and providing better protection for the first connector 21.

[0080] In some examples, along the arrangement direction of the support portion 11 and the connecting portion 12, i.e., in the third direction, the length of the second protective member 33 is greater than the length of the portion of the first connector 21 located on the side of the connecting portion 12 opposite to the support portion 11. In this way, when the power battery 400 is impacted or subjected to shock, the second protective member 33 can withstand the impact force or shock, thereby providing better protection for the first connector 21.

[0081] In some embodiments, please continue reading Figure 3The second connector 22 is connected to one side of the second protective member 33 in a second direction, which is perpendicular to the first direction and also perpendicular to the arrangement direction of the supporting part 11 and the connecting part 12. This reduces the space occupied by the second connector 22 in the first direction, allowing for a more rational arrangement of the first protective member 31, the second protective member 33, the first connector 21, and the second connector 22, thus providing better protection for both. Furthermore, when the power battery 400 is subjected to a collision or impact, both the first protective member 31 and the second protective member 33 can protect the second connector 22, improving the protective effect on the second connector 22.

[0082] In some embodiments, along the arrangement direction of the support portion 11 and the connecting portion 12, i.e., the third direction, the length of the first protective member 31 is greater than the length of the portion of the second connector 22 located on the side of the connecting portion 12 opposite to the support portion 11. In this way, when the power battery 400 is impacted or subjected to shock, the first protective member 31 can withstand the impact force or shock, thereby providing better protection for the second connector 22.

[0083] In some embodiments, along the arrangement direction of the support portion 11 and the connecting portion 12, i.e., the third direction, the length of the second protective member 33 is greater than the length of the portion of the second connector 22 located on the side of the connecting portion 12 opposite to the support portion 11. In this way, when the power battery 400 is impacted or subjected to shock, the second protective member 33 can withstand the impact force or shock, thereby providing better protection for the second connector 22.

[0084] In some other embodiments, the protective structure 3 may also be a plurality of rod-shaped or block-shaped structures surrounding the connector 2. Alternatively, the protective structure 3 may be a cylindrical structure surrounding the connector 2.
