TECHNICAL FIELD

[0001] The present application belongs to the field of vehicles, and particularly relates to a vehicle. BACKGROUND

[0002] With the development of science and technology, vehicles have become a high-frequency traffic tool for people's daily travel. And installing a battery pack in the vehicle to provide power for the vehicle has also become a common means. Usually, when installing a battery pack in a vehicle, the battery pack is connected to the floor or other structures in the vehicle through a hanger, that is, the hanger is connected to the battery pack, part of the hanger extends out of the battery pack, and when it is necessary to connect the battery pack to the floor or other structures in the vehicle, the part of the hanger extending out of the battery pack is connected to the floor or other structures in the vehicle, so as to realize the connection of the battery pack to the floor or other structures in the vehicle. However, in the related art, when the vehicle is in a harsh environment or a harsh working condition, the part of the hanger extending out of the battery pack is prone to aging and failure. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the embodiments of the present application is to provide a vehicle, which at least solves the problem that the part of the hanger extending out of the battery pack is prone to aging and failure.

[0004] The embodiments of the present application provide a vehicle, which comprises a battery pack;

[0005] The battery pack comprises a shell, an upper cover, a hanger and a first sealing member;

[0006] The upper cover is arranged above the shell, the shell is provided with a beam, the upper cover is provided with a connecting hole, and the hanger is fixedly connected to the beam through the connecting hole;

[0007] The first sealing member is located on the surface of the upper cover away from the shell, at least part of the hanger extending out of the upper cover is surrounded by the first sealing member, and when the hanger fixes the battery pack to a component of the vehicle, the first sealing member is clamped by the component and the upper cover.

[0008] Optionally, the battery pack further comprises a nest, and the nest comprises a connecting part and a mounting part in an integrated structure;

[0009] The connecting part is configured to be clamped between the upper cover and the beam;

[0010] The mounting part is configured to be in interference fit with the connecting hole, the mounting part protrudes the connecting part in a direction away from the beam, the mounting part is provided with a through hole, and the hanger is configured to be fixedly connected to the beam through the through hole.

[0011] Optionally, the battery pack further comprises a second sealing member;

[0012] The mounting part has a sealing groove at one end away from the beam, the sealing groove extends along the circumferential direction of the mounting part, and the second sealing element is disposed in the sealing groove;

[0013] The mounting component includes a cover portion that covers the sealing groove and abuts against the second sealing component.

[0014] Optionally, the mount further includes a connecting portion, the cover portion and the connecting portion are an integral structure, and the cover portion is located in the middle of the connecting portion. The portion of the connecting portion located on one side of the cover portion passes through the through hole and is fixedly connected to the beam, and the portion of the connecting portion located on the other side of the cover portion is fixedly connected to the vehicle components.

[0015] Optionally, the connecting portion has a receiving groove on its surface facing the upper cover. The receiving groove extends along the circumferential direction of the connecting portion and contains structural adhesive. The surface of the connecting portion facing the upper cover and the surface of the upper cover facing the housing are connected by the structural adhesive.

[0016] Optionally, the battery pack further includes an insert;

[0017] The beam is provided with mounting holes, the insert is fixedly installed on the wall of the mounting hole, and the hanger passes through the through hole and is fixedly connected to the insert, so that the hanger is fixedly connected to the beam.

[0018] Optionally, the mounting portion has a boss plane around the through hole on the side facing the beam, and the boss plane abuts against the end of the insert.

[0019] Optionally, the battery pack further includes an insulating sheet;

[0020] The insulating sheet has a through hole that passes through the insulating sheet. The insulating sheet is connected to the surface of the connecting part away from the mounting part, and the boss plane passes through the through hole. The projection portion of the insulating sheet in the axial direction of the through hole coincides with the cell module of the battery pack.

[0021] Optionally, the top cover includes a first region and a second region connected together, the connecting hole is disposed in the first region, and the thickness of the first region is greater than the thickness of the second region.

[0022] In this embodiment, since the top cover is located above the housing, the top cover and the housing can enclose a closed space, protecting the components within the housing. Because the housing contains beams and the top cover has connection holes, the mounting component passes through these holes and is fixedly connected to the beams. Therefore, when it is necessary to connect the battery pack to vehicle components, the portion of the mounting component located outside the housing can be directly connected to the vehicle components, i.e., the portion of the mounting component extending beyond the top cover can be connected to the vehicle components, thus enabling the connection between the battery pack and vehicle components. Since the first seal is connected to the surface of the top cover away from the receiving cavity, and at least a portion of the mounting member extending from the top cover is surrounded by the first seal, when the battery pack is connected to a vehicle component, the portion of the mounting member located outside the housing is connected to the vehicle component, and the first seal is in contact with the vehicle component. The first seal is then compressed by the vehicle component, i.e., the first seal is clamped between the component and the top cover. This ensures that after the portion of the mounting member located outside the housing is connected to the vehicle component, this portion of the mounting member is protected by the first seal, preventing liquids or other corrosive substances from contacting this portion of the mounting member, thereby effectively preventing this portion of the mounting member from aging and failing easily. In this embodiment, by providing a first seal on the surface of the top cover away from the housing, and by surrounding at least a portion of the mounting member extending from the top cover with the first seal, once the battery pack needs to be installed in the vehicle and the mounting member located outside the housing is connected to the vehicle components, the first seal can seal the gap between the top cover and the vehicle components. This protects the portion of the mounting member located outside the housing from contact with liquids or corrosive substances under harsh operating conditions, thereby preventing the mounting member from aging and failing easily.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] like Figures 1 to 5 As shown, the vehicle includes a battery pack, which includes a housing, a top cover 10, a mounting bracket 20, and a first seal 30.

[0034] The top cover 10 is located above the housing, and a beam 40 is provided in the housing. The top cover 10 is provided with a connecting hole 101. The mounting member 20 passes through the connecting hole 101 and is fixedly connected to the beam 40. The first sealing member 30 is connected to the surface of the top cover 10 away from the housing. At least part of the mounting member 20 extending out of the top cover 10 is surrounded by the first sealing member 30. When the mounting member 20 fixes the battery pack to the vehicle component, the first sealing member 30 is clamped between the component and the top cover 10.

[0035] In this embodiment, the housing has a receiving cavity and an opening, the opening communicating with the receiving cavity, and the upper cover 10 covering the opening. Furthermore, when the mounting member 20 passes through the connection hole 101 on the upper cover 10, part of the mounting member 20 is located outside the housing, and part of the mounting member 20 is located inside the housing; that is, part of the mounting member 20 extends out of the upper cover 10, and the part of the mounting member 20 extending out of the upper cover 10 is connected to a component of the vehicle.

[0036] In this embodiment, since the upper cover 10 is located above the housing, the upper cover 10 and the housing can enclose a closed space, protecting the components inside the housing. Because the housing has a beam 40 and the upper cover 10 has a connection hole 101, the mounting member 20 passes through the connection hole 101 and is fixedly connected to the beam 40. Therefore, when it is necessary to connect the battery pack to vehicle components, the portion of the mounting member 20 located outside the housing can be directly connected to the vehicle components, that is, the portion of the mounting member 20 extending out of the upper cover 10 can be connected to the vehicle components, thereby achieving the connection between the battery pack and vehicle components. Since the first seal 30 is located on the surface of the upper cover 10 away from the receiving cavity, and at least a portion of the mounting member 20 extending from the upper cover 10 is surrounded by the first seal 30, when the battery pack is connected to a vehicle component, the portion of the mounting member 20 located outside the housing is connected to the vehicle component, and the first seal 30 contacts the vehicle component. The first seal 30 is then compressed by the vehicle component, i.e., the first seal 30 is clamped between the component and the upper cover 10. This ensures that after the portion of the mounting member 20 located outside the housing is connected to the vehicle component, the portion of the mounting member 20 is protected by the first seal 30, preventing liquids or other corrosive substances from contacting the portion of the mounting member 20, thereby effectively preventing the portion of the mounting member 20 from aging and failing easily. In this embodiment, by providing a first sealing element 30 on the surface of the top cover 10 away from the housing, and surrounding at least a portion of the mounting member 20 extending from the top cover 10 with the first sealing element 30, once the battery pack needs to be installed in the vehicle and the mounting member 20 located outside the housing is connected to the vehicle components, the first sealing element 30 can seal the gap between the top cover 10 and the vehicle components. This protects the portion of the mounting member 20 located outside the housing from contact with liquids or corrosive substances under harsh operating conditions, thereby preventing the mounting member 20 from aging and failing easily.

[0037] It should be noted that the vehicle component can be the vehicle floor, or other components, but this application does not limit the specific components.

[0038] In addition, the top cover 10 can be connected to the housing at the opening of the housing by fasteners, including but not limited to bolts, screws, etc.

[0039] In addition, in this embodiment, the first sealing element 30 may be formed of rubber. Of course, the first sealing element 30 may also be formed of silicone. The specific material of the first sealing element 30 is not limited in this embodiment.

[0040] In addition, in this embodiment, the first sealing element 30 can be bonded to the upper cover 10 with adhesive. Of course, the first sealing element 30 can also be disposed on the upper cover 10 by injection molding. This embodiment does not limit the scope of the application.

[0041] In addition, in this embodiment, beam 40 can be a longitudinal beam, but it can also be a transverse beam. This embodiment does not limit the specific type of beam. Beam 40 is used to increase the strength of the battery pack casing.

[0042] In addition, in this embodiment, when at least a portion of the mounting member 20 extending from the upper cover 10 is surrounded by the first sealing member 30, the first sealing member 30 surrounds the mounting member 20 in the circumferential direction, that is, in the circumferential direction of the mounting member 20, the first sealing member 30 surrounds the mounting member 20 at least once.

[0043] In some embodiments, the height of the first seal 30 may be less than or equal to the height of the portion of the mount 20 extending from the top cover 10. With this arrangement, when the portion of the mount 20 extending from the top cover 10 is connected to a vehicle component, the first seal 30 can be compressed, and the amount of compression of the first seal 30 is small. This facilitates the connection of the mount 20 to the vehicle component and ensures that the gap between the battery pack and the vehicle component is effectively sealed by the first seal 30.

[0044] The height of the first seal 30 refers to the distance between the end of the first seal 30 away from the upper cover 10 and the end of the first seal 30 close to the upper cover 10. The height of the part of the mounting member 20 extending out of the upper cover 10 refers to the distance between the end of the part of the mounting member 20 extending out of the upper cover 10 away from the upper cover 10 and the surface of the upper cover 10.

[0045] Of course, the height of the first seal 30 can also be greater than the height of the portion of the mounting member 20 extending from the upper cover 10. In this case, when the portion of the mounting member 20 extending from the upper cover 10 is connected to the vehicle components, the first seal 30 is compressed, and the amount of compression of the first seal 30 is relatively large. This embodiment of the present application does not limit this aspect. Furthermore, when the height of the first seal 30 is greater than or equal to the height of the portion of the mounting member 20 extending from the upper cover 10, it is equivalent to the entire portion of the mounting member 20 being surrounded by the first seal 30; when the height of the first seal 30 is less than the height of the portion of the mounting member 20 extending from the upper cover 10, it is equivalent to only a portion of the mounting member 20 being surrounded by the first seal 30.

[0046] Additionally, in some embodiments, such as Figure 1 As shown, the battery pack may also include a nest 50, which includes a connector 51 and a mounting portion 52 of an integral structure; the connector 51 is configured to be sandwiched between the upper cover 10 and the beam 40; the mounting portion 52 is configured to be interference-fitted with the connector hole 101, the mounting portion 52 protrudes from the connector 51 in a direction away from the beam 40, and the mounting portion 52 is provided with a through hole 522, the mounting member 20 is configured to pass through the through hole 522 and be fixedly connected to the beam 40.

[0047] Since the mounting portion 52 is configured to have an interference fit with the connecting hole 101, and the connecting portion 51 is configured to be sandwiched between the upper cover 10 and the beam 40, the mounting portion 52 can increase the strength of the upper cover 10 at the connecting hole 101. Furthermore, the connecting portion 51 can also increase the strength of the portion of the upper cover 10 around the connecting hole 101. In addition, the mounting portion 52 is essentially fixed relative to the connecting hole 101, effectively preventing potential wobbling. Because the mounting portion 52 has a through hole 522, the mounting member 20 can pass through this through hole 522 and connect to the beam 40, thus the mounting portion 52 does not affect the connection between the mounting member 20 and the beam 40. In other words, by providing the nesting 50, the strength of the upper cover 10 can be increased on the one hand, and the fixed connection between the mounting member 20 and the beam 40 can be ensured on the other.

[0048] It should be noted that the material of the nest 50 can be an alloy, or it can be steel. The specific material of the nest 50 is not limited in this embodiment.

[0049] In addition, in this embodiment, the connecting part 51 can be connected to the surface of the upper cover 10 facing the housing to prevent the connecting part 51 from shaking.

[0050] Additionally, in some embodiments, such as Figure 1As shown, the battery pack may also include a second seal 60; the mounting part 52 is provided with a sealing groove 521 at one end away from the beam 40, the sealing groove 521 extends along the circumferential direction of the mounting part 52, and the second seal 60 is disposed in the sealing groove 521; the mounting member 20 includes a cover part 22, the cover part 22 covers the sealing groove 521 and abuts against the second seal 60.

[0051] Because the mounting part 52 has a sealing groove 521 at one end away from the beam 40, and the sealing groove 521 extends along the circumferential direction of the mounting part 52, and the second seal 60 is disposed in the sealing groove 521, when the mounting member 20 passes through the through hole 522 on the mounting part 52, the cover part 22 can contact the end of the mounting part 52 away from the beam 40, and at the same time, the cover part 22 contacts the second seal 60. Thus, the second seal 60 can effectively seal the gap between the cover part 22 and the mounting part 52, effectively preventing impurities or liquids from the outside of the battery pack from entering the battery pack through this gap and affecting the internal components. In other words, by providing the second seal 60, the internal components of the battery pack can be effectively protected, preventing them from being affected by impurities or liquids from the outside. When the battery pack is installed in a vehicle, by providing the second seal 60 on top of the first seal 30, it is equivalent to performing a secondary seal on the battery pack, effectively ensuring the good performance of the battery pack.

[0052] In this embodiment, the height of the second seal 60 can be greater than the depth of the sealing groove 521, thereby ensuring that the second seal 60 is squeezed by the capping part 22, so that the second seal 60 seals the gap between the capping part 22 and the mounting part 52.

[0053] It should be noted that the second seal 60 can be formed of rubber, or it can be formed of silicone. The specific material of the second seal 60 is not limited in this embodiment.

[0054] In addition, in this embodiment of the application, the mount 20 also includes a connecting part 21, the cover part 22 and the connecting part 21 are an integral structure, and the cover part 22 is located in the middle of the connecting part 21. The part of the connecting part 21 located on one side of the cover part 22 passes through the through hole 522 and is fixedly connected to the beam 40, and the part of the connecting part 21 located on the other side of the cover part 22 is fixedly connected to the vehicle components.

[0055] With this configuration, when the mount 20 passes through the through hole 522 on the mounting portion 52, a portion of the connecting part 21 on one side of the cover portion 22 can pass through the through hole 522 and be fixedly connected to the beam 40. Furthermore, when it is necessary to connect the battery pack to a vehicle component, a portion of the connecting part 21 on the other side of the cover portion 22 extends out of the battery pack, thereby fixing this portion of the connecting part 21 to the vehicle component, thus achieving the connection between the battery pack and the vehicle component. In other words, by providing the connecting part 21, it is convenient for the mount 20 to mount the battery pack to the vehicle, thus facilitating the connection between the battery pack and the vehicle component.

[0056] It should be noted that the cover part 22 can be a flange, and the connecting part 21 can be a connecting rod. The flange is located in the middle of the connecting rod, and the flange and the connecting rod are an integral structure. In addition, the integral structure of the cover part 22 and the connecting part 21 can effectively improve the strength of the mounting component 20.

[0057] Additionally, in some embodiments, such as Figure 1 As shown, a receiving groove 512 is provided on the surface of the connecting part 51 facing the upper cover 10. The receiving groove 512 extends along the circumferential direction of the connecting part and contains structural adhesive 001. The surface of the connecting part 51 facing the upper cover 10 is connected to the surface of the upper cover 10 facing the housing by the structural adhesive 001. With this arrangement, the connecting part 51 is bonded by the structural adhesive 001, which can avoid the problem of the connecting part 51 easily separating from the upper cover 10, ensuring the overall structural stability of the battery pack. Furthermore, by providing the structural adhesive 001, it is also convenient to connect the connecting part 51 to the upper cover 10.

[0058] It should be noted that in this embodiment, the mounting part 52 can be a cylindrical structure, and the connecting part 51 can be a plate-like structure. Additionally, in this embodiment, the surface of the connecting part 51 facing the upper cover 10 may not have a receiving groove 512; that is, the surface of the connecting part 51 facing the upper cover 10 is a plane, which is directly bonded to the upper cover 10 with structural adhesive 001.

[0059] In some embodiments, the battery pack may also include an insert 70; the beam 40 is provided with a mounting hole, the insert 70 is fixedly installed on the wall of the hole forming the mounting hole, and the hanger 20 passes through the through hole 522 and is fixedly connected to the insert 70 so that the hanger 20 is fixedly connected to the beam 40.

[0060] Because the beam 40 has mounting holes, and the insert 70 is fixedly installed on the wall of the mounting holes, the insert 70 can effectively increase the strength of the beam 40. It also allows the mount 20 to pass through the through hole 522 on the mounting part 52 and connect to the insert 70, thus fixing the mount 20 to the beam 40. This is equivalent to connecting the mount 20 to a high-strength component, ensuring stable connection of the mount 20 when it is subsequently connected to vehicle components. In other words, by setting the insert 70, after connecting the mount 20 to vehicle components, it ensures stable connection of the mount 20 inside the battery pack and increases the strength of the beam 40.

[0061] It should be noted that the insert 70 can be installed in the mounting hole by welding, that is, welding the insert 70 to the weld point 002 on the wall of the mounting hole, thereby fixing the insert 70. Of course, the insert 70 can also be installed in the mounting hole by other means, such as by bolting the insert 70 into the mounting hole, that is, by connecting the insert 70 to the wall of the mounting hole with bolts.

[0062] The embodiments described in this application are not limited in this respect.

[0063] Furthermore, in this embodiment, the insert 70 can be made of an alloy, or it can be made of steel. The specific material of the insert 70 is not limited in this embodiment.

[0064] In some embodiments, the insert 70 is provided with a threaded hole 701, and the mount 20 is provided with threads. The mount 20 and the insert 70 are connected by the threads and the threaded hole 701. With this arrangement, when it is necessary to connect the mount 20 and the insert 70, the mount 20 and the insert 70 can be directly connected by threads, which facilitates the connection between the mount 20 and the insert 70, and also facilitates the removal of the mount 20.

[0065] It should be noted that when the mount 20 includes a connecting portion 21 and a cover portion 22 disposed on the connecting portion 21, a thread can be provided on the portion of the connecting portion 21 located on one side of the cover portion 22. This allows the connecting portion 21 to be fitted into the threaded hole 701 of the insert 70 when the mount 20 needs to be connected to the insert 70, thus achieving a threaded connection between the mount 20 and the insert 70. Additionally, a thread can also be provided on the portion of the connecting portion 21 located on the other side of the cover portion 22, facilitating the connection between the mount 20 and vehicle components when this portion of the connecting portion 21 is connected.

[0066] In some embodiments, the connecting portion 51 facing the beam 40 has a boss plane 511 around the through hole 522, the through hole 522 extends to the boss plane 511 and passes through the boss plane 511, and the boss plane 511 abuts against the end of the insert 70.

[0067] Since the connecting part 51 has a boss plane 511 around the through hole 522 on the side facing the beam 40, the size of the boss plane 511 is smaller than that of the connecting part 51. Therefore, once the boss plane 511 abuts against the end of the insert 70, it ensures a relatively flat contact between the boss plane 511 and the insert 70. Furthermore, the through hole 522 on the mounting part 52 extends to and through the boss plane 511, thereby preventing the boss plane 511 from affecting the hanger 20 and ensuring a connection between the hanger 20 and the insert 70. In other words, by providing the boss plane 511, it is easier to make the surface of the boss plane 511 facing away from the connecting part 51 flat, ensuring a relatively flat contact surface between the boss plane 511 and the insert 70, and reducing manufacturing complexity.

[0068] Additionally, in some embodiments, such as Figure 1 As shown, the battery pack may also include an insulating sheet 80; the insulating sheet 80 is provided with a through hole, the through hole passes through the insulating sheet 80, the insulating sheet 80 is connected to the surface of the connecting part 51 away from the mounting part 52, and the boss plane 511 passes through the through hole, and the projection portion of the insulating sheet 80 in the axial direction of the through hole 522 coincides with the cell module 100 of the battery pack.

[0069] A battery pack typically contains a cell module 100 located within a housing. Electrodes are mounted on the cell module 100. An insulating sheet 80 is provided, connected to the surface of the connecting portion 51 facing away from the mounting portion 52. A boss plane 511 passes through a through hole. The axial projection of the insulating sheet 80 in the through hole 522 coincides with the cell module 100 of the battery pack. This effectively prevents the cell module 100 from contacting the connecting portion 51, which could lead to leakage and subsequent energy transfer to the connecting portion 51, the top cover 10, and the mounting bracket 20, thus ensuring the safety of the vehicle occupants. In other words, the use of the insulating sheet 80 effectively improves the safety of the battery pack.

[0070] It should be noted that in this embodiment, the insulating sheet 80 can be made of rubber. Of course, the insulating sheet 80 can also be made of other non-conductive materials, such as plastic. The specific material of the insulating sheet 80 is not limited in this embodiment. Furthermore, the insulating sheet 80 can be bonded to the surface of the connecting portion 51 facing away from the mounting portion 52 using structural adhesive 001.

[0071] In some embodiments, the top cover 10 may include a first region 11 and a second region 12 connected together, with a connection hole 101 disposed in the first region 11. The thickness of the first region 11 is greater than the thickness of the second region 12. This arrangement effectively increases the thickness of the portion of the top cover 10 where the connection hole 101 is located, thus locally thickening the top cover 10. This increases the strength of the portion of the top cover 10 where the connection hole 101 is located, thereby improving the strength of the top cover 10 at the mounting member 20.
