[0024] Please refer to the following: Figure 1 , Figure 2 and Figure 3 This application provides a sealing member 100, which includes a sealing part 10 and an adhesive part 20. The adhesive part 20 is disposed on one side of the sealing part 10. The sealing part 10 includes a protrusion 11 protruding away from the adhesive part 20. The side of the protrusion 11 facing the adhesive part 20 has a receiving space 111. The side of the protrusion 11 away from the adhesive part 20 is provided with an anti-slip part 12.

[0025] Specifically, the sealing part 10 is the core part that realizes the sealing function of the sealing element 100. The adhesive part 20 is used to fix the sealing element 100 to the target surface (such as a cover plate, equipment housing, etc.). Double-sided tape, hot melt adhesive or other adhesive materials can be used, depending on the requirements, and no restrictions are imposed here.

[0026] A protrusion 11 extending outward (i.e., away from the adhesive portion 20) is provided in the sealing portion 10. The protrusion 11 can improve the sealing contact area between the sealing portion 10 and the target surface, thereby adapting to surfaces of different shapes. The receiving space 111 formed by the protrusion 11 can reserve space for other components (such as screws, wires, etc. fixed on the target structure) or hole structures without affecting the overall sealing performance of the sealing portion 10, and provide a sealing effect for other components or hole structures.

[0027] Furthermore, an anti-slip part 12 is provided on the other side of the protrusion 11 (i.e. the side away from the adhesive part 20). The anti-slip part 12 on the protrusion 11 can increase the friction and facilitate the gripping and installation of the seal 100.

[0028] In one embodiment, a plurality of anti-slip portions 12 are provided on the side of the protrusion 11 away from the adhesive portion 20. The plurality of anti-slip portions 12 are spaced apart on the surface of the protrusion 11, thereby increasing the anti-slip area of ​​the anti-slip portions 12 on the protrusion 11 and further facilitating the removal and installation of the seal 100.

[0029] In this embodiment, the anti-slip portion 12 is an anti-slip rib. In other embodiments, the anti-slip portion 12 can be any one or more of the following: a textured structure (e.g., wavy, striped, granular), an uneven structure, or a rubber-based high-friction material coating. For example, the anti-slip portion 12 can be a striped textured structure, wherein the stripes can also be covered with a rubber-based high-friction material coating, thereby improving the anti-slip performance of the seal 100. The specific design depends on the requirements and is not limited here.

[0030] In the aforementioned seal 100, the traditional single-function seal 100 is upgraded to a composite sealing structure with multiple functions such as buffering, anti-slip, and adhesion. The various parts cooperate with each other to improve the sealing reliability and applicability of the seal 100. Specifically, the sealing part 10 is bonded to the target surface (e.g., the battery tray 40 of the battery pack 200) through the adhesive part 20. The protrusion 11 on the sealing part 10 can improve the sealing effect, and the receiving space 111 formed by the protrusion 11 can effectively absorb and disperse the stress generated by compression or thermal expansion, thereby improving the product reliability of the seal 100. At the same time, the anti-slip part 12 on the protrusion 11 can increase the friction, making it convenient to grip and install the seal 100.

[0031] Please refer to the following: Figure 3 and Figure 4In one embodiment, the sealing portion 10 further includes a first straight portion 13, a second straight portion 14, and a transition portion 15. The first straight portion 13 surrounds the edge of the protrusion 11 and is connected to the side of the protrusion 11 facing the adhesive portion 20. The second straight portion 14 surrounds the edge of the first straight portion 13 and is located between the adhesive portion 20 and the first straight portion 13. The adhesive portion 20 is bonded to the side of the second straight portion 14 opposite to the first straight portion 13. The transition portion 15 connects the first straight portion 13 and the second straight portion 14.

[0032] Specifically, the first straight portion 13 is a platform or edge extending from the side of the protrusion 11 facing the adhesive portion 20. The first straight portion 13 provides support for the protrusion 11 and prevents excessive deformation of the protrusion 11. The second straight portion 14 is larger than the first straight portion 13 and surrounds the first straight portion 13. The second straight portion 14 is a larger platform area used to support the adhesive portion 20 or other structures. The transition portion 15 is a connecting structure used to connect the first straight portion 13 and the second straight portion 14, thereby buffering stress concentration and improving the structural strength of the seal 100.

[0033] Please continue reading. Figure 3 and Figure 4 In one embodiment, the cross-section of the transition portion 15 is arc-shaped, that is, the transition portion 15 is a smoothly transitioning arc-shaped area to connect the first straight portion 13 (near the protrusion 11) and the second straight portion 14 (near the adhesive portion 20). The arc-shaped structure can effectively alleviate the stress concentration between the first straight portion 13 and the second straight portion 14, and reduce the risk of the sealing portion 10 breaking or fatigue damage due to rigid transition.

[0034] In other embodiments, the cross-section of the transition portion 15 is inclined, that is, the transition portion 15 is a ramp-like structure formed by one plane tilting at a certain angle to another plane. The inclined structure is simpler and facilitates the processing and manufacturing of the sealing portion 10.

[0035] Please continue reading. Figure 3 and Figure 4 In one embodiment, the protrusion 11, the first straight portion 13, the transition portion 15, and the second straight portion 14 are integrally formed, thereby improving the structural strength of the sealing portion 10.

[0036] In another embodiment, the protrusion 11, the first straight portion 13, the transition portion 15, and the second straight portion 14 can be separate structures and are combined into a sealing portion 10 by welding.

[0037] Please continue reading. Figure 3 and Figure 4In one embodiment, the thickness of the sealing portion 10 is 1mm-1.5mm, that is, the thickness of the protrusion 11, the first straight portion 13, the transition portion 15 and the second straight portion 14 are all 1mm-1.5mm. For example, the thickness of the sealing portion 10 is 1mm, 1.25mm or 1.5mm, which is set according to the requirements and is not limited here.

[0038] In one embodiment, the sealing part 10 is made of metal, such as aluminum, and the surface of the sealing part 10 is anodized to give the sealing part 10 excellent corrosion resistance and improve the service life of the sealing part 100.

[0039] Please continue reading. Figure 3 and Figure 4 In one embodiment, the material of the adhesive portion 20 includes a thermosetting adhesive, and the thickness of the adhesive portion 20 is 1.5mm-2mm, for example, the thickness of the adhesive portion 20 is 1.5mm, 1.75mm, or 2mm. By appropriately pressing the adhesive portion 20, the adhesive portion 20 can be adapted to effectively bond and seal curved surfaces with a flatness ≤1mm.

[0040] In one embodiment, the initial adhesive force of the adhesive portion 20 is greater than or equal to 10 N / cm. Combined with the metal sealing portion 10 made of aluminum, the risk of the seal 100 moving or falling off after being bonded and installed in the vertical, anti-gravity direction can be reduced.

[0041] In one embodiment, the aforementioned thermosetting adhesive can be cured by baking at 140°C for 20 minutes. After curing, it can form an effective seal on the target surface, meeting the IP67 requirement. Here, IP describes a device's protection against the ingress of solid objects and liquids. The first digit after IP indicates the dustproof rating (from 0 to 6), representing the ability to prevent the entry of solid foreign objects. The second digit after IP indicates the waterproof rating (from 0 to 8), representing the ability to prevent liquid intrusion. IP67 indicates a dustproof rating of 6 and a waterproof rating of 7, indicating good sealing performance.

[0042] In one embodiment, after the above-mentioned thermosetting adhesive is cured, its shear strength is ≥5 MPa and its high temperature resistance can reach 600°C or higher. In the event of runaway of the target surface (for example, when the target surface is the battery pack 200, the battery pack 200 will experience thermal runaway), the sealing performance of the adhesive part 20 can still meet the IP67 requirement.

[0043] Please continue reading. Figure 3 and Figure 4In one embodiment, the seal 100 further includes release paper 30, which is peelable and disposed on the side of the adhesive portion 20 opposite to the sealing portion 10. It is understood that the adhesive portion 20 is covered with peelable release paper 30 before the seal 100 is adhered to the target surface, thereby improving the cleanliness of the seal 100 during manufacturing or transportation. When adhering the seal 100 to the target surface, the release paper 30 is first peeled off to expose the adhesive layer, and then the seal 100 is adhered to the target surface.

[0044] Please refer to it again. Figure 1 , Figure 2 and Figure 3 This application also provides a battery pack 200, which includes a battery tray 40, a connector 50 and a seal 100. The connector 50 is used to fix the battery tray 40 to the vehicle body 60. The sealing part 10 in the seal 100 is bonded to the battery tray 40 by the adhesive part 20, and the receiving space 111 formed by the protrusion 11 is used to receive the connector 50.

[0045] Specifically, the seal 100 includes a sealing portion 10 and an adhesive portion 20. The adhesive portion 20 is disposed on one side of the sealing portion 10. The sealing portion 10 includes a protrusion 11 protruding away from the adhesive portion 20. The side of the protrusion 11 facing the adhesive portion 20 has a receiving space 111. The side of the protrusion 11 away from the adhesive portion 20 is provided with an anti-slip portion 12.

[0046] The battery tray 40 is a structural component that supports battery modules or cells. The connector 50 is a fastener, such as a bolt, used to secure the battery tray 40 to the vehicle body 60. The sealing part 10 uses the adhesive part 20 to firmly adhere the seal 100 to the surface of the battery tray 40. The space enclosed by the protrusion 11 can be used to wrap the connector 50, forming a partially sealed environment to prevent moisture and dust from entering. The anti-slip part 12 increases the friction of the seal 100, making it easier to pick up and install the seal 100 on the battery tray 40.

[0047] The sealing part 10 is the core part that realizes the sealing function of the sealing element 100. The adhesive part 20 is used to fix the sealing element 100 to the battery tray 40. Double-sided tape, hot melt adhesive or other adhesive materials can be used, depending on the requirements, and no restrictions are made here.

[0048] A protrusion 11 extending outward (i.e., away from the adhesive portion 20) is provided in the sealing portion 10. The protrusion 11 can improve the sealing contact area between the sealing portion 10 and the battery tray 40, thereby adapting to different shaped surfaces. The receiving space 111 formed by the protrusion 11 can reserve space for the connector without affecting the overall sealing performance of the sealing portion 10, and provide a sealing effect for the connector.

[0049] Furthermore, an anti-slip part 12 is provided on the other side of the protrusion 11 (i.e. the side away from the adhesive part 20). The anti-slip part 12 on the protrusion 11 can increase the friction and facilitate the gripping and installation of the seal 100.

[0050] In one embodiment, a plurality of anti-slip portions 12 are provided on the side of the protrusion 11 away from the adhesive portion 20. The plurality of anti-slip portions 12 are spaced apart on the surface of the protrusion 11, thereby increasing the anti-slip area of ​​the anti-slip portions 12 on the protrusion 11 and further facilitating the removal and installation of the seal 100.

[0051] In this embodiment, the anti-slip portion 12 is an anti-slip rib. In other embodiments, the anti-slip portion 12 can be any one or more of the following: a textured structure (e.g., wavy, striped, granular), an uneven structure, or a rubber-based high-friction material coating. For example, the anti-slip portion 12 can be a striped textured structure, wherein the stripes can also be covered with a rubber-based high-friction material coating, thereby improving the anti-slip performance of the seal 100. The specific design depends on the requirements and is not limited here.

[0052] In the aforementioned battery pack 200, the sealing part 10 is bonded to the battery tray 40 by the adhesive part 20. The protrusion 11 on the sealing part 10 can improve the sealing effect of the connector 50, and the receiving space 111 formed by the protrusion 11 can effectively absorb and disperse the stress caused by compression or thermal expansion, thereby improving the product reliability of the sealing part 100. At the same time, the anti-slip part 12 on the protrusion 11 can increase the friction, making it convenient to grip and install the sealing part 100.

[0053] In one embodiment, the connector 50 is an FDS screw (self-tapping screw). It is understood that the connector 50 can also be other fasteners, depending on the requirements, and no restrictions are imposed here.

[0054] In this embodiment, a battery pack 200 includes 24 connectors 50, and a seal 100 can be used to seal 6 connectors 50.

[0055] Please refer to it again. Figure 3 and Figure 4 In one embodiment, the sealing portion 10 further includes a first straight portion 13, a second straight portion 14, and a transition portion 15.

The second straight portion 14 surrounds the edge of the first straight portion 13 and is located between the adhesive portion 20 and the first straight portion 13. The adhesive portion 20 is bonded to the side of the second straight portion 14 opposite to the first straight portion 13. The transition portion 15 connects the first straight portion 13 and the second straight portion 14.

[0056] Specifically, the first straight portion 13 is a platform or edge extending from the side of the protrusion 11 facing the adhesive portion 20. The first straight portion 13 provides support for the protrusion 11 and prevents excessive deformation of the protrusion 11. The second straight portion 14 is larger than the first straight portion 13 and surrounds the first straight portion 13. The second straight portion 14 is a larger platform area used to support the adhesive portion 20 or other structures. The transition portion 15 is a connecting structure used to connect the first straight portion 13 and the second straight portion 14, thereby buffering stress concentration and improving the structural strength of the seal 100.

[0057] Please continue reading. Figure 3 and Figure 4 In one embodiment, the cross-section of the transition portion 15 is arc-shaped, that is, the transition portion 15 is a smoothly transitioning arc-shaped area to connect the first straight portion 13 (near the protrusion 11) and the second straight portion 14 (near the adhesive portion 20). The arc-shaped structure can effectively alleviate the stress concentration between the first straight portion 13 and the second straight portion 14, and reduce the risk of the sealing portion 10 breaking or fatigue damage due to rigid transition.

[0058] In one embodiment, the seal 100 further includes release paper 30, which is peelable and disposed on the side of the adhesive portion 20 opposite to the sealing portion 10. It is understood that the peelable release paper 30 covers the adhesive portion 20 before the seal 100 is adhered to the target surface, thereby improving the cleanliness of the seal 100 during manufacturing or transportation. When adhering the seal 100 to the battery tray 40, the release paper 30 is first peeled off to expose the adhesive layer, and then the seal 100 is adhered to the battery tray 40.

[0059] In one embodiment, the adhesive portion 20 attaches the sealing portion 10 to the battery tray 40 to form an effective seal, meeting the IP67 requirement. IP67 indicates a dustproof rating of 6 and a waterproof rating of 7, signifying good sealing performance.

[0060] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 5 This application also provides a vehicle 300, including a body 60 and a battery pack 200, wherein the battery pack 200 is connected to the body 60.

[0061] The battery pack 200 includes a battery tray 40, a connector 50, and a seal 100. The connector 50 is used to fix the battery tray 40 to the vehicle body 60. The sealing part 10 of the seal 100 is bonded to the battery tray 40 by the adhesive part 20, and the receiving space 111 formed by the protrusion 11 is used to receive the connector 50.

The side of the protrusion 11 away from the adhesive portion 20 is provided with an anti-slip portion 12.

[0063] The battery tray 40 is a structural component that supports battery modules or cells. The connector 50 is a fastener, such as a bolt, used to secure the battery tray 40 to the vehicle body 60. The sealing part 10 uses the adhesive part 20 to firmly adhere the seal 100 to the surface of the battery tray 40. The space enclosed by the protrusion 11 can be used to wrap the connector 50, forming a partially sealed environment to prevent moisture and dust from entering.
