The entire content of the above - referenced application is incorporated herein by reference.

[0002] This disclosure relates to the field of vehicles, and more particularly, to vehicles.

Background Art

[0003] In the prior art, in existing vehicles, at least a part of the battery structure may be used as the vehicle floor. When the vehicle body and the battery are connected, when the vehicle crosses water, in order to prevent liquid from entering the vehicle interior through the gap between the vehicle body and the battery, the gap between the vehicle body and the battery needs to be sealed. However, in the prior art, the sealing between the vehicle body and the battery is uncertain, and the vehicle has a risk of waterlogging.

Summary of the Invention

[0004] This disclosure is intended to at least partly solve one of the technical problems in the prior art.

[0005] The object of this disclosure is to propose a vehicle. The vehicle can prevent the uncertain sealing between the vehicle body and the battery in order to alleviate the waterlogging problem of the vehicle and improve the product quality of the vehicle.

[0006] The vehicle according to this disclosure includes a vehicle body, a battery, and a sealing assembly. The sealing assembly is positioned between the vehicle body and the battery. The sealing assembly includes a sealing plate and a sealing member. The sealing plate is fixed to and sealed to the battery. The surface of the sealing plate opposite to the battery has a mounting surface. The sealing member is positioned on the mounting surface. The sealing member is sandwiched between the vehicle body and the sealing plate, so that the vehicle body and the battery jointly define a passenger compartment, or the vehicle body and the sealing assembly jointly define a passenger compartment.

[0007] According to the vehicle of this disclosure, a sealing plate having a mounting surface is positioned between the sealing member and the battery, and the sealing member is mounted on the mounting surface. As a result, after the sealing plate is fixed to the battery and sealed, it is possible to prevent a gap from forming between the sealing member and the battery.

[0010] Embodiments of this disclosure are described in detail below. Examples of embodiments are shown in the accompanying drawings. Throughout this description, identical or similar elements, or elements having the same or similar function, are denoted by the same or similar reference numerals. The embodiments described below with reference to the accompanying drawings are illustrative and used solely to illustrate this disclosure and should not be construed as limiting this 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 is driven by a battery 10 which supplies power to the motor of the vehicle 100, causing the vehicle 100 to move.

[0012] A vehicle 100 according to embodiments of the present disclosure, as shown in Figures 1 to 9, includes a body 30, a battery 10, and a sealing assembly 20. The battery 10 can supply power to the motor of the vehicle 100. The body 30 is positioned above the battery 10 in the height direction of the vehicle 100, and the sealing assembly 20 is positioned between the body 30 and the battery 10. The sealing assembly 20 is configured to seal the gap between the body 30 and the battery 10. In some specific embodiments, the body 30 and the battery 10 jointly define a passenger compartment 40. An enclosed environment can be formed in the passenger compartment 40. The passenger compartment 40 can accommodate occupants. A portion of the structure of the battery 10 corresponding to the passenger compartment 40 is constructed as the 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 body 30 and occupants.

[0013] Of course, in some other specific embodiments, the vehicle body 30 and the sealed assembly 20 jointly define the passenger compartment 40. A portion of the structure of the sealed assembly 20 corresponding to the passenger compartment 40 is constructed as the floor of the vehicle 100. Specifically, at least a portion of the structure of the sealed assembly 20 may be used as the floor of the vehicle 100. The sealed assembly 20 may be configured to support the vehicle body 30 and the occupants. The sealed assembly 20 also includes a sealed plate 201 and a sealed member 202. The sealed plate 201 is fixed to and sealed with the battery 10. The battery 10 specifically includes a heat exchange plate 101. The heat exchange plate 101 is fixed to and sealed with the sealed plate 201. In some embodiments, a connecting structure is filled between the sealed plate 201 and the heat exchange plate 101. The connecting structure fixes and seals the sealed plate 201 and the heat exchange plate 101. The connecting structure filled between the sealing plate 201 and the heat exchange plate 101 may be formed of solder or glue. In other words, the sealing plate 201 and the heat exchange plate 101 may be connected by welding, adhesive, etc. Specifically, the sealing plate 201 cannot be moved relative to the battery 10, and the sealing plate 201 and the heat exchange plate 101 are fixedly connected by welding, adhesive, etc. The connecting structure between the sealing plate 201 and the heat exchange plate 101, formed of a connecting material such as solder and adhesive, can seal the gap between the sealing plate 201 and the heat exchange plate 101, thereby preventing liquid from entering the vehicle compartment 40 through the gap between the sealing plate 201 and the heat exchange plate 101, and the vehicle compartment 40 can have the 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 positioned on the mounting surface 203. The sealing member 202 may, for example, be bonded to the mounting surface 203. Note 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 positioning the sealing member 202 on the mounting surface 203, the sealing member 202 can be fully pressed against the mounting surface 203, and the sealing member 202 can seal the gap between the sealing member 202 and the mounting surface 203, so that 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 the desired sealing effect.

[0015] In addition, the sealing member 202 is sandwiched between the vehicle body 30 and the sealing plate 201. In other words, the sealing member 202 is in contact with both the vehicle body 30 and the sealing plate 201. Since the mounting surface 203 does not have significant irregularities, if the sealing member 202 has a constant thickness throughout the entire sealing member, the surface of the sealing member 202 that contacts the vehicle body 30 will have a constant height throughout the entire surface after the sealing member 202 is attached to the mounting surface 203. When the sealing member 202 abuts against and is fitted to the vehicle body 30, the sealing member 202 can be fully attached to the vehicle body 30, and the sealing member 202 can seal the gap between the sealing member 202 and the vehicle body 30, so that 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 the desired sealing effect.

[0016] In this way, to improve the sealing effect of the vehicle compartment 40, by arranging a sealing plate 201 having a mounting surface 203 between the sealing member 202 and the battery 10, the sealing assembly 20 can achieve the desired seal 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 to the conventional technology, 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 mitigating the water ingress problem of the vehicle 100 and further improving the product quality of the vehicle 100.

[0017] In some embodiments of this disclosure, as shown in Figures 1 to 5 and Figures 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 the passenger compartment. In other words, the heat exchange plate 101 can be used as the floor of the vehicle 100.

[0018] The heat exchange plate 101 defines heat exchange channels 102, through which the refrigerant can flow. Furthermore, the heat exchange plate 101 has multiple heat exchange channels 102. These multiple heat exchange channels 102 are arranged continuously 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 plane. 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 plane, the thickness of the thermally conductive adhesive between the battery core and the heat exchange plate 101 becomes uniform, allowing for uniform heat exchange between the battery core and the heat exchange plate 101. Therefore, all of the multiple heat exchange channels 102 defined by the heat exchange plate 101 protrude toward the vehicle body 30. The sealing plate 201 is positioned between the sealing member 202 and the heat exchange plate 101. The sealing plate 201 has a first sealing portion 204. The first sealing portion 204 is fixed to the heat exchange plate 101 and sealed together. The first sealing portion 204 corresponds to each of the heat exchange channels 102.

[0019] The first sealing portion 204 is specifically positioned opposite the heat exchange channel 102 and can be connected to the heat exchange channel by welding, bonding, or the like. In some embodiments, the surface of the first sealing portion 204 connected to the outer wall of the heat exchange channel 102 may conform to the outer shape of the outer wall of the heat exchange channel 102. The surface of the first sealing portion 204 connected to the heat exchange plate 101 is specifically constructed as a profiled surface (a surface that has been profiled). In this way, the connection area between the first sealing portion 204 and the heat exchange plate 101 can be increased, which is beneficial in improving the connection strength between the first sealing portion 204 and the heat exchange plate 101, and also in enhancing the sealing effect between the first sealing portion 204 and the heat exchange plate 101. Of course, in some other embodiments, as shown in Figure 5, the surface of the first sealing portion 204 connected to the outer wall of the heat exchange channel 102 may be constructed as a plane. The surface of the first sealing portion 204 connected to the heat exchange plate 101 is specifically constructed as a flat surface. In this way, the difficulty of processing and assembling the sealing plate 201 may be reduced, and the production cost of the vehicle 100 may be reduced.

[0020] In some embodiments, the outer wall of the heat exchange flow path 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 to the first connecting portion of the heat exchange plate 101 and can be hermetically connected. The first sealing portion 204 can be connected to the first connecting portion, for example, by welding or adhesion, whereby the first sealing portion 204 can be securely connected to the connecting portion of the heat exchange plate 101. In addition, a connecting structure formed by a connecting material such as solder or an adhesive can seal the gap between the first sealing portion 204 and the heat exchange plate 101, thereby preventing liquid from entering the gap between the first sealing portion 204 and the heat exchange plate 101, and further preventing the liquid from further entering the passenger compartment 40. This is beneficial for maintaining the passenger compartment 40 in a dry state and improving the product quality of the vehicle 100. Further, the surface where the first connecting portion is connected to the first sealing portion 204 is constructed as a flat surface. In some specific embodiments, the width dimension of the first connecting portion may be 1 mm or more. In this way, the connection range between the first connecting portion and the first sealing portion 204 may be expanded, whereby the connection between the first sealing portion 204 and the heat exchange plate 101 can be made more secure, the first sealing portion 204 can be prevented from falling off from the heat exchange plate 101, and the sealing effect between the first sealing portion 204 and the heat exchange plate 101 can be further improved.

[0021] In some embodiments of the present disclosure, as shown in Figures 1 to 8, the first sealing portion 204 has a mounting surface 203 formed on the first sealing portion. The battery core is located inside the battery 10 along the radial direction of the vehicle 100, and the heat exchange channel 102 is densely arranged inside the heat exchange plate 101 corresponding to the battery core. Correspondingly, the first sealing portion 204 is positioned close to the inside of the sealing plate 201 to be connected to the heat exchange channel 102, and the surface on which the vehicle body 30 is connected and fitted to the sealing member 202 is located on a projection of the first sealing portion 204. The first sealing portion 204 can therefore be positioned facing the vehicle body 30, and the first sealing portion 204 forms the mounting surface 203 so that irregularities are less likely 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, it can be prevented that the gap between the sealing member 202 and the mounting surface 203 will affect the sealing effect of the vehicle compartment 40.

[0022] In some embodiments of the present disclosure, as shown in FIGS. 1 to 8, the sealing plate 201 further has a second sealing portion 205. The heat exchange plate 101 has a second connecting portion. The second connecting portion is disposed at the edge of the heat exchange plate 101 and surrounds the outside of the heat exchange flow path 102. The second sealing portion 205 is fixed to and hermetically connected to the heat exchange plate 101. The second sealing portion 205 is disposed corresponding to the second connecting portion. The heat exchange flow path 102 is disposed close 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 path 102. In other words, when the first sealing portion 204 corresponds to the heat exchange flow path 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. As shown in FIG. 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 connection strength between the heat exchange plate 101 and the sealing plate 201 can be improved, further preventing the heat exchange plate 101 from being separated from the sealing plate 201, and the sealing effect between the heat exchange plate 101 and the sealing plate 201 can be enhanced. In this way, the liquid cannot penetrate into the gap between the second sealing portion 205 and the heat exchange plate 101. Also in this case, the liquid further cannot penetrate into the gap between the first sealing portion 204 and the heat exchange plate 101, which is beneficial for further preventing the liquid from penetrating into the passenger compartment 40 and further improving the product quality of the vehicle 100.

[0023] In some embodiments of this disclosure, as shown in Figure 5, a connecting flange 206 is connected between the first sealing portion 204 and the second sealing portion 205 to make the height of the first sealing portion 204 greater than the height of the second sealing portion 205. The connecting flange 206 is positioned between the first sealing portion 204 and the second sealing portion 205. The connecting flange 206 may extend along the height direction of the vehicle 100. One end of the connecting flange 206 may be connected to the first sealing portion 204. The other end of the connecting flange 206 may be connected to the second sealing portion 205. By making the height of the first sealing portion 204 not match the height of the second sealing portion 205, the first sealing portion 204 can be connected to and fitted to the heat exchange channel 102 protruding from the heat exchange plate 101, and the second sealing portion 205 can be connected to and fitted to a second connecting portion of the heat exchange plate 101 that is lower than the heat exchange channel 102. Both the first sealing portion 204 and the second sealing portion 205 can be attached to the heat exchange plate 101, that is, the sealing plate 201 can be aligned with the heat exchange plate 101, thereby ensuring a secure connection between the sealing plate 201 and the heat exchange plate 101, and further preventing liquid from entering the gap between the sealing plate 201 and the heat exchange plate 101.

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

[0025] In some embodiments of this disclosure, as shown in Figures 1 to 4, 7, and 8, the sealing member 202 can be constructed in a ring shape, i.e., the sealing member 202 can be constructed as a sealing ring. By constructing the sealing member 202 as an annular structure, it is possible to ensure that there are no gaps in the circumferential side walls of the sealing member 202. When the sealing member 202 is sandwiched between the vehicle body 30 and the sealing plate 201, liquid cannot flow directly into the vehicle compartment 40 through the sealing member 202. In addition, the sealing member 202 can be aligned with the circumferential outer wall of the vehicle body 30. In this way, the sealing member 202 is completely fitted to the surface of the vehicle body 30 in close proximity to the battery 10, thereby preventing water ingress 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 the desired sealing performance, and therefore the sealing member 202 can have the desired elasticity. When the vehicle 100 travels on an uneven road in the vertical direction of the vehicle 100, causing the vehicle body 30 to shake, the sealing member 202 is compressed or repelled, ensuring that the sealing member 202 and the vehicle body 30 do not separate, thereby improving the sealing effect of the vehicle compartment 40.

[0026] In some embodiments of the present invention, when the sealing member 202 is constructed as an annular sealing ring, the cross-sectional width dimension of the sealing member 202 before compression deformation is L1, and the cross-sectional thickness dimension of the sealing member 202 before compression deformation is L2, and these 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 fully mounted on the surface of the vehicle body 30 adjacent to the battery 10, even if mounting errors exist on the circumferential outer edge of the vehicle body 30, thereby reducing the impact of mounting errors on the vehicle body 30 on the sealing effect of the passenger compartment 40 and further improving the product quality of the vehicle 100.

[0027] In some embodiments of this disclosure, the sealing member 202 has a contact portion that contacts the vehicle body 30. After the vehicle body 30 contacts the contact portion, the vehicle body 30 can compress the contact portion under the influence of gravity, reducing the thickness dimension of the contact portion after compression. If the thickness dimension of the contact portion after the vehicle body 30 contacts the contact portion is set to L3, then the following relationship, L3 ≥ 4 mm, is satisfied. In other words, the thickness of the contact portion after compression is 4 mm or more. When the vehicle 100 travels on an uneven road, the vehicle body 30 may further compress the contact portion as it shakes. By setting the thickness of the contact portion after it has been compressed to 4 mm or more, the sealing member 202 can exert a cushioning effect against the vehicle body 30 when the contact portion is further compressed, thereby making it less likely for the vehicle body 30 to collide with the sealing plate 201, preventing damage and failure of the heat exchange plate 101 as a result of the collision, which effectively improves the operational stability of the battery 10.

[0028] In some embodiments of this disclosure, the sealing member 202 and / or the vehicle body 30 are coated with a hydrophobic coating. The hydrophobic coating may be placed between the sealing member 202 and the vehicle body 30. The hydrophobic coating has desired hydrophobic properties. By spraying the hydrophobic coating onto the outer surface of the sealing member 202, the hydrophobic coating can prevent liquid from accumulating at the point where the sealing member 202 contacts the vehicle body 30, and further prevent liquid from entering the passenger compartment 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 onto the outer surface of the vehicle body 30 that contacts the sealing member 202, or the hydrophobic coating may be sprayed onto 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 point where the sealing member 202 contacts the vehicle body 30, thereby further mitigating the problem of water ingress into the passenger compartment 40.

[0029] Furthermore, to test whether the seal between the vehicle body 30 and the battery 10 is effective, the tester may compress the contact area to a thickness of 4 mm, control the pressure inside the compartment 40 to 10 kPa, maintain the compartment 40 of the vehicle 100 at that pressure for 30 seconds, and then leave the compartment undisturbed for 60 seconds. In this case, a drop in air pressure inside the compartment 40 of 100 Pa or less demonstrates 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.
