[0010]

[0023] The embodiments of the present disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings. Throughout the description, identical or similar elements, or elements having identical or similar functions, are designated by identical or similar reference numerals. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0011] A vehicle 100 according to an embodiment of the present disclosure will be described below with reference to Figures 1 to 9. The vehicle 100 may be an electric vehicle 100. The electric vehicle 100 uses a battery 10 to supply power to a motor of the vehicle 100, which drives the vehicle 100 to run.

[0012] As shown in FIGS. 1 to 9 , a vehicle 100 according to an embodiment of the present disclosure includes a body 30, a battery 10, and a sealing assembly 20. The battery 10 can supply power to a motor of the vehicle 100. The body 30 is disposed above the battery 10 in the height direction of the vehicle 100, and the sealing assembly 20 is disposed between the body 30 and the battery 10. The sealing assembly 20 is configured to seal a gap between the body 30 and the battery 10. In some specific embodiments, the body 30 and the battery 10 collectively define a vehicle cabin 40. An enclosed environment can be formed in the vehicle cabin 40. The vehicle cabin 40 can accommodate occupants. A portion of the structure of the battery 10 corresponding to the vehicle cabin 40 is constructed as a floor of the vehicle 100. Specifically, at least a portion of the structure of the battery 10 may be used as the floor of the vehicle 100. The battery 10 can be configured to support the vehicle body 30 and occupants.

[0013] Of course, in some other specific embodiments, the vehicle body 30 and the sealing assembly 20 collectively define the vehicle compartment 40. A portion of the structure of the sealing assembly 20 corresponding to the vehicle compartment 40 is constructed as a floor of the vehicle 100. Specifically, at least a portion of the structure of the sealing assembly 20 may be used as the floor of the vehicle 100. The sealing assembly 20 may be configured to support the vehicle body 30 and occupants. The sealing assembly 20 additionally includes a sealing plate 201 and a sealing member 202. The sealing plate 201 is fixed and sealingly connected to the battery 10. The battery 10 specifically includes a heat exchanger plate 101. The heat exchanger plate 101 is fixed and sealingly connected to the sealing plate 201. In some embodiments, a connecting structure is filled between the sealing plate 201 and the heat exchanger plate 101. The connecting structure fixes and sealingly connects the sealing plate 201 and the heat exchanger plate 101. The connecting structure filled between the sealing plate 201 and the heat exchanger plate 101 may be formed with solder or glue. In other words, the sealing plate 201 and the heat exchanger plate 101 may be connected by welding, adhesive, or the like. Specifically, the sealing plate 201 cannot move relative to the battery 10, and the sealing plate 201 and the heat exchanger plate 101 are fixedly connected by welding, adhesive, or the like. The connecting structure between the sealing plate 201 and the heat exchanger plate 101 formed with a connecting material such as solder or adhesive can seal the gap between the sealing plate 201 and the heat exchanger plate 101, thereby preventing liquid from entering the vehicle interior 40 through the gap between the sealing plate 201 and the heat exchanger plate 101, and allowing the vehicle interior 40 to have a desired sealing effect.

[0014] Furthermore, the surface of the sealing plate 201 opposite to the battery 10 has a mounting surface 203. The sealing member 202 is disposed on the mounting surface 203. The sealing member 202 may be, for example, glued to the mounting surface 203. It should be noted that the mounting surface 203 is constructed as a flat surface. There is no significant variation in the height of the mounting surface 203. By disposing the sealing member 202 on the mounting surface 203, the sealing member 202 can be fully seated on the mounting surface 203 and can seal the gap between the sealing member 202 and the mounting surface 203. As a result, liquid cannot enter the vehicle compartment 40 through the gap between the sealing member 202 and the mounting surface 203, and the vehicle compartment 40 can have a desired sealing effect.

[0015] The sealing member 202 is also sandwiched between the vehicle body 30 and the sealing plate 201. In other words, the sealing member 202 contacts both the vehicle body 30 and the sealing plate 201. Because the mounting surface 203 does not have any significant irregularities, if the sealing member 202 has a constant thickness over its entirety, the surface of the sealing member 202 that contacts the vehicle body 30 will have a constant height over its entirety after the sealing member 202 is mounted on the mounting surface 203. When the sealing member 202 abuts and fits against the vehicle body 30, the sealing member 202 can be completely mounted to the vehicle body 30 and can seal the gap between the sealing member 202 and the vehicle body 30. As a result, liquid cannot enter the vehicle compartment 40 through the gap between the sealing member 202 and the vehicle body 30, and the vehicle compartment 40 can have a desired sealing effect.

[0016] In this way, by disposing the sealing plate 201 having the mounting surface 203 between the sealing member 202 and the battery 10 to improve the sealing effect of the vehicle compartment 40, the sealing assembly 20 can achieve desired sealing between the sealing plate 201 and the battery 10, between the sealing member 202 and the sealing plate 201, and between the sealing member 202 and the vehicle body 30. Compared with the prior art, gaps are less likely to occur between the vehicle body 30 and the battery 10. The sealing assembly 20 prevents liquid from entering the vehicle compartment 40 through the gap between the vehicle body 30 and the battery 10, thereby alleviating the water leakage problem of the vehicle 100 and further improving the product quality of the vehicle 100.

[0017] In some embodiments of the present disclosure, as shown in Figures 1 to 5 and 7 to 9, the heat exchange plate 101 is configured to exchange heat with the battery core of the battery 10. Specifically, the heat exchange plate 101 can heat or cool the battery core so that the battery core can operate at a desired operating temperature. The heat exchange plate 101 and the vehicle body 30 together define a vehicle compartment. In other words, the heat exchange plate 101 can be used as a floor of the vehicle 100.

[0018] The heat exchange plate 101 defines heat exchange channels 102 through which a refrigerant can flow. The heat exchange plate 101 further includes a plurality of heat exchange channels 102. The plurality of heat exchange channels 102 are continuously arranged on the surface of the heat exchange plate 101. The surface of the heat exchange plate 101 adjacent to the battery core is constructed as a flat surface. Heat is conducted between the battery core and the heat exchange plate 101 via a thermally conductive adhesive. By constructing the surface of the heat exchange plate 101 adjacent to the battery core as a flat surface, the thickness of the thermally conductive adhesive between the battery core and the heat exchange plate 101 is made uniform, allowing for uniform heat exchange between the battery core and the heat exchange plate 101. Therefore, all of the plurality of heat exchange channels 102 defined by the heat exchange plate 101 protrude toward the vehicle body 30. The sealing plate 201 is disposed between the sealing member 202 and the heat exchange plate 101. The sealing plate 201 has first sealing portions 204. The first sealing portions 204 are fixed to and sealingly connected to the heat exchange plate 101. The first sealing portions 204 correspond to the heat exchange flow paths 102, respectively.

[0019] The first sealing portion 204 is specifically disposed opposite the heat exchange passage 102 and can be connected to the heat exchange passage 102 by welding, adhesive, or the like. In some embodiments, the surface of the first sealing portion 204 connected to the outer wall of the heat exchange passage 102 can be adapted to the contour of the outer wall of the heat exchange passage 102. The surface of the first sealing portion 204 connected to the heat exchange plate 101 is specifically constructed as a profiled surface. In this way, the connection area between the first sealing portion 204 and the heat exchange plate 101 can be increased, which is beneficial to improving the connection strength between the first sealing portion 204 and the heat exchange plate 101 and also the sealing effect between the first sealing portion 204 and the heat exchange plate 101. Of course, in some other embodiments, as shown in FIG. 5, the surface of the first sealing portion 204 connected to the outer wall of the heat exchange passage 102 can be constructed as a flat surface. The surface of the first sealing portion 204 coupled with the heat exchange plate 101 is specifically constructed as a flat surface, so that the processing and assembly difficulties of the sealing plate 201 may be reduced, and the production costs of the vehicle 100 may be reduced.

[0020] In some embodiments, the outer wall of the heat exchange flow passage 102 connected to the first sealing portion 204 protrudes toward the sealing plate 201 to form a first connecting portion. The first sealing portion 204 can be fixed and hermetically connected to the first connecting portion of the heat exchange plate 101. The first sealing portion 204 can be connected to the first connecting portion by, for example, welding or adhesive, so that the first sealing portion 204 can be securely connected to the connecting portion of the heat exchange plate 101. In addition, the connecting structure formed by a connecting material such as solder or adhesive can seal the gap between the first sealing portion 204 and the heat exchange plate 101, thereby preventing liquid from seeping into the gap between the first sealing portion 204 and the heat exchange plate 101 and further preventing liquid from seeping into the passenger compartment 40, which is beneficial because it keeps the passenger compartment 40 dry and improves the product quality of the vehicle 100. Furthermore, the surface where the first connecting portion is connected to the first sealing portion 204 is constructed as a plane. In some specific embodiments, the width dimension of the first connecting portion may be 1 mm or more. In this way, the connection area between the first connecting portion and the first sealing portion 204 may be enlarged, which may make the connection between the first sealing portion 204 and the heat exchange plate 101 more reliable, prevent the first sealing portion 204 from falling off the heat exchange plate 101, and further improve the sealing effect between the first sealing portion 204 and the heat exchange plate 101.

[0021] In some embodiments of the present disclosure, as shown in FIGS. 1 to 8 , the first sealing portion 204 has a mounting surface 203 formed thereon. The battery core is located inside the battery 10 along the radial direction of the vehicle 100, and the heat exchange passage 102 is closely arranged inside the heat exchange plate 101 to correspond to the battery core. Correspondingly, the first sealing portion 204 is arranged close to the inside of the sealing plate 201 to be connected to the heat exchange passage 102, and the surface of the vehicle body 30 that is connected to and fitted with the sealing member 202 is located at a protruding portion of the first sealing portion 204. The first sealing portion 204 can therefore be arranged opposite the vehicle body 30, and the first sealing portion 204 completely forms the mounting surface 203 so that unevenness is unlikely to occur on the mounting surface 203. In this way, the sealing member 202 can be completely attached to the mounting surface 203, and thereafter, any gap between the sealing member 202 and the mounting surface 203 can be prevented from affecting the sealing effect of the passenger compartment 40.

[0022] In some embodiments of the present disclosure, as shown in FIGS. 1 to 8 , the sealing plate 201 further includes a second sealing portion 205. The heat exchange plate 101 includes a second connecting portion. The second connecting portion is disposed on the edge of the heat exchange plate 101 and surrounds the outside of the heat exchange flow passage 102. The second sealing portion 205 is fixed to and sealingly connected to the heat exchange plate 101. The second sealing portion 205 is disposed corresponding to the second connecting portion. The heat exchange flow passage 102 is disposed adjacent to the inside of the heat exchange plate 101, and the edge of the heat exchange plate 101 is located outside the heat exchange flow passage 102. In other words, when the first sealing portion 204 corresponds to the heat exchange flow passage 102 and the second sealing portion 205 corresponds to the edge of the heat exchange plate 101, the second sealing portion 205 is located outside the first sealing portion 204. 9, the surface of the second connecting portion connected to the sealing plate 201 is constructed as a plane. By attaching and fixing the second sealing portion 205 to the second connecting portion, the connecting strength between the heat exchanger plate 101 and the sealing plate 201 can be improved, and the heat exchanger plate 101 can be prevented from being separated from the sealing plate 201, thereby improving the sealing effect between the heat exchanger plate 101 and the sealing plate 201. In this way, liquid cannot penetrate into the gap between the second sealing portion 205 and the heat exchanger plate 101, and in this case, liquid also cannot penetrate into the gap between the first sealing portion 204 and the heat exchanger plate 101, which is beneficial because it further prevents liquid from penetrating into the passenger compartment 40 and further improves the product quality of the vehicle 100.

[0023] 5 , a connecting flange 206 is connected between the first sealing portion 204 and the second sealing portion 205 so that the height of the first sealing portion 204 is greater than the height of the second sealing portion 205. The connecting flange 206 is disposed between the first sealing portion 204 and the second sealing portion 205. The connecting flange 206 can extend along the height direction of the vehicle 100. One end of the connecting flange 206 can be connected to the first sealing portion 204. The other end of the connecting flange 206 can be connected to the second sealing portion 205. By making the height of the first sealing portion 204 different from the height of the second sealing portion 205, the first sealing portion 204 can be connected and fitted to the heat exchange passage 102 protruding from the heat exchange plate 101, and the second sealing portion 205 can be connected and fitted to a second connecting portion of the heat exchange plate 101 that is lower than the heat exchange passage 102. Both the first sealing portion 204 and the second sealing portion 205 can be attached to the heat exchange plate 101, i.e., the sealing plate 201 is aligned with the heat exchange plate 101, thereby ensuring a reliable connection between the sealing plate 201 and the heat exchange plate 101 and further preventing liquid from seeping into the gap between the sealing plate 201 and the heat exchange plate 101.

[0024] In some embodiments of the present disclosure, as shown in FIGS. 1 to 4 , 7 , and 8 , the sealing plate 201 defines an escape hole 207 for escaping the battery 10. The escape hole 207 corresponds to the passenger compartment 40. The escape hole 207 is located inside the outer peripheral wall of the vehicle body 30 in the radial direction of the sealing plate 201, i.e., the escape hole 207 is located in the passenger compartment 40. The escape hole 207 allows at least a portion of the structure of the heat exchange plate 101 of the battery 10 to be located inside the passenger compartment 40 so that the heat exchange plate 101 can be used as a floor of the vehicle 100. In addition, by providing the escape hole 207 in the sealing plate 201, the escape hole 207 reduces the weight of the sealing plate 201, thereby reducing the overall weight of the vehicle 100 and enabling the vehicle 100 to meet lightweight design requirements.

[0025] In some embodiments of the present disclosure, as shown in FIGS. 1 to 4 , 7 , and 8 , the sealing member 202 may be constructed in a ring shape, i.e., the sealing member 202 may be constructed as a sealing ring. By constructing the sealing member 202 as an annular structure, no gaps may exist on the circumferential sidewall of the sealing member 202. When the sealing member 202 is sandwiched between the vehicle body 30 and the sealing plate 201, liquid cannot directly flow through the sealing member 202 into the vehicle compartment 40. The sealing member 202 may also be aligned with the circumferential outer wall of the vehicle body 30. In this manner, the sealing member 202 is completely attached to the surface of the vehicle body 30 that is close to the battery 10, thereby preventing water from seeping in between the sealing member 202 and the vehicle body 30. In some embodiments, the sealing member 202 may be made of a rubber material. The rubber material has a desired sealing performance, and therefore the sealing member 202 may have a desired elasticity. When the vehicle 100 travels on a road that is bumpy in the height direction of the vehicle 100 and the vehicle body 30 sways, the sealing member 202 is compressed or rebounded, ensuring that the sealing member 202 and the vehicle body 30 are not separated, thereby improving the sealing effect of the passenger compartment 40.

[0026] In some embodiments of the present invention, when the sealing member 202 is constructed as an annular sealing ring, the sealing member 202 has a cross-sectional width dimension L1 before compression deformation and a cross-sectional thickness dimension L2 before compression deformation, which satisfy the following relationship: L1≧2L2. In other words, the cross-sectional width dimension of the sealing member 202 before compression deformation is at least twice the cross-sectional thickness dimension. This design ensures that the sealing member 202 can be perfectly attached to the surface of the vehicle body 30 that is close to the battery 10, even if there is an attachment error at the circumferential outer edge of the vehicle body 30. This reduces the impact of attachment error of the vehicle body 30 on the sealing effect of the passenger compartment 40 and further improves the product quality of the vehicle 100.

[0027] In some embodiments of the present disclosure, the sealing member 202 has an abutment portion that abuts against the vehicle body 30. After the vehicle body 30 abuts against the abutment portion, the vehicle body 30 can crush the abutment portion under the influence of gravity of the vehicle body 30, reducing the thickness dimension of the abutment portion after being crushed. If the thickness dimension of the abutment portion after the vehicle body 30 abuts against the abutment portion is set as L3, the following relationship is satisfied: L3≧4 mm. In other words, the thickness of the abutment portion after being crushed is 4 mm or greater. When the vehicle 100 travels on a bumpy road, the vehicle body 30 may further crush the abutment portion when it sways. By setting the thickness of the abutment portion after being crushed to 4 mm or more, the sealing member 202 can exert a cushioning effect on the vehicle body 30 when the abutment portion is further crushed, thereby making it less likely for the vehicle body 30 to collide with the sealing plate 201, and preventing damage and breakdown of the heat exchange plate 101 resulting from the collision, which effectively improves the operational stability of the battery 10.

[0028] In some embodiments of the present disclosure, the sealing member 202 and / or the vehicle body 30 are coated with a hydrophobic coating. The hydrophobic coating may be disposed between the sealing member 202 and the vehicle body 30. The hydrophobic coating has desired hydrophobic properties. By spraying the hydrophobic coating on the outer surface of the sealing member 202, the hydrophobic coating can prevent liquid from accumulating at the position where the sealing member 202 abuts the vehicle body 30 and further prevent liquid from seeping into the vehicle interior 40 through the gap between the sealing member 202 and the vehicle body 30. Of course, in some other embodiments, the hydrophobic coating may also be sprayed on the outer surface of the vehicle body 30 that contacts the sealing member 202, or the hydrophobic coating may be sprayed on both the outer surface of the vehicle body 30 that contacts the sealing member 202 and the outer surface of the sealing member 202. In this way, it is ensured that liquid is less likely to accumulate at the position where the sealing member 202 abuts the vehicle body 30, thereby further mitigating the problem of water seepage into the vehicle interior 40.

[0029] Furthermore, to test whether the sealing between the vehicle body 30 and the battery 10 is effective, the tester may compress the contact portion to a thickness of 4 mm, control the pressure in the cabin 40 to 10 kPa, maintain the cabin 40 of the vehicle 100 at that pressure for 30 seconds, and let the cabin stand for 60 seconds. In this case, a drop in air pressure in the cabin 40 of 100 Pa or less demonstrates an excellent sealing between the vehicle body 30 and the battery 10, thereby preventing serious water ingress problems from occurring in the vehicle 100 after it leaves the factory.
