[0052] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0053] The vehicle body assembly 1 according to an embodiment of the present invention will be described below with reference to the drawings.

[0054] As Figures 1 - 6 shown, the vehicle body assembly 1 according to an embodiment of the present invention includes a vehicle frame 10, an upper cover 21, a tray 30, and a seal 41.

[0055] The vehicle frame 10 includes two support beams 11 arranged along a first direction. The upper cover 21 is fixed between the two support beams 11, which is convenient for improving the structural strength of the vehicle frame 10, thereby improving the load-bearing capacity of the vehicle frame 10 and enhancing the safety factor of the vehicle.

[0056] The upper cover 21 and the support beam 11 jointly define an upper box body 20. The upper box body 20 is provided with a receiving cavity having an open mouth. The tray 30 is disposed below the upper cover 21. The tray 30 is fixedly connected to the upper box body 20 to close the open mouth, thereby closing the receiving cavity to protect the components in the receiving cavity. For example, a battery assembly 60 is placed in the receiving cavity, and the tray 30 closes the open mouth to provide a relatively enclosed working space for the battery assembly 60 and protect the battery assembly 60.

[0057] Specifically, the upper box body 20 and the tray 30 jointly form the box body of the battery pack, and the upper cover 21 is a part of the box body. In this way, the structural strength of the vehicle frame 10 is enhanced by using the upper cover 21, and a part of the upper box body 20 is formed by using the support beam 11 of the vehicle frame 10. On the one hand, it is convenient to improve the structural compactness, and the upper box body 20 is arranged by using the space between the two support beams 11 to improve the space utilization rate. On the other hand, it is convenient to reduce the number of components, reduce the installation steps, etc., reduce the complexity of the structure, and reduce the production cost.

[0058] The seal 41 is disposed between the upper box body 20 and the tray 30. The seal 41 is in contact with the upper box body 20 and the tray 30 respectively to seal the gap between the upper box body 20 and the tray 30 by using the seal 41, reducing the possibility that liquids or dust and other objects will enter the receiving cavity, so as to fully protect the components in the receiving cavity.

[0059] Therefore, the vehicle body assembly 1 according to the embodiment of the present invention defines the upper box body 20 of the battery pack by using the vehicle frame 10 and the upper cover 21. At the same time, the gap between the upper box body 20 and the tray 30 is sealed by using the seal 41, so as to improve the sealing reliability between the upper box body 20 and the tray 30, reduce the possibility of water entering the accommodation cavity, and further reduce the possibility of failure of the battery assembly 60 in the accommodation cavity.

[0060] The vehicle body assembly 1 according to the specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0061] In some specific embodiments of the present invention, as Figures 1 - 6 shown, the vehicle body assembly 1 includes a vehicle frame 10, an upper cover 21, a tray 30 and a seal 41.

[0062] In some embodiments of the present invention, the seal 41 is configured to be elastically deformable at least in the height direction to ensure the abutting force between the seal 41 and the upper box body 20 and the tray 30.

[0063] Specifically, enabling the seal 41 to be elastically deformable in the height direction can, on the one hand, compensate for the installation error between the upper box body 20 and the tray 30 in the height direction. On the other hand, when the vehicle shakes and the seal 41 shakes, it can also maintain the abutting fit between the tray 30 and / or the upper box body 20 and the seal 41, so that the seal 41 can seal the gap between the tray 30 and the upper box body 20, thereby reducing the possibility of water or dust and other objects entering the accommodation cavity, and further fully protecting the components in the accommodation cavity.

[0064] In some embodiments of the present invention, as Figure 8 shown, in the height direction, the first part 401 of the seal 41 is located between the upper box body 20 and the tray 30, and in the horizontal direction, the second part 402 of the seal 41 is located between the upper box body 20 and the tray 30, so as to seal the gap between the upper box body 20 and the tray 30 respectively from the height direction and the horizontal direction, realizing double sealing, so as to fully reduce the possibility of dust or liquid entering the accommodation cavity through the gap between the upper box body 20 and the tray 30, and further protect the components in the accommodation cavity.

[0065] Specifically, when one of the sealing surfaces of the seal 41 fails in the height direction and the horizontal direction, the other sealing surface can still be used to seal the upper box body 20 and the tray 30, which is convenient for improving the sealing reliability.

[0066] In some embodiments, as Figure 7As shown, the upper box body 20 is arranged above the tray 30. Above the seal 41, there are a first abutting protrusion 415 and a second abutting protrusion 416 that exceed its top wall. The first abutting protrusion 415 is located outside the second abutting protrusion 416. The first abutting protrusion 415 and the second abutting protrusion 416 define an annular receiving groove.

[0067] Among them, in the height direction, the first part 401 of the seal 41 seals the gap between the upper box body 20 and the tray 30. Specifically, the lower bottom wall of the seal 41 abuts and cooperates with the tray 30, and the first abutting protrusion 415 abuts and cooperates with the upper box body 20 to seal the gap between the tray 30 and the upper box body 20 in the height direction.

[0068] The second abutting protrusion 416 defines the second part 402 of the seal 41. Specifically, the side wall of the second part 402 facing the first abutting protrusion 415 abuts and cooperates with the upper box body 20, and the side wall of the second part 402 facing away from the first abutting protrusion 415 abuts and cooperates with the sealing tray 30 to seal the gap between the tray 30 and the upper box body 20 in the horizontal direction.

[0069] In some embodiments, as Figure 8 shown, the vehicle body assembly 1 further includes a sealing gasket 58. The sealing gasket 58 is located between the second part 402 and the upper box body 20 to seal the gap between the tray 30 and the upper box body 20 in the horizontal direction together with the second part 402.

[0070] In some examples, a part of the sealing gasket 58 extends into the first abutting protrusion 415 and the second abutting protrusion 416 to use the first abutting protrusion 415 and the second abutting protrusion 416 to limit the position of the sealing gasket 58, so that the sealing gasket 58 can seal the gap between the tray 30 and the upper box body 20 in the horizontal direction together with the second part 402.

[0071] In some examples, as Figure 8 shown, the lower wall surface of the seal 41 defines a positioning groove 413. There is a positioning block 32 on the tray 30. The positioning block 32 extends into the positioning groove 413 to cooperate with the positioning groove 413, thereby limiting the position of the seal 41.

[0072] In some embodiments, as Figure 7 shown, the vehicle body assembly 1 includes an elastic member. A part of the elastic member is arranged between the first part 401 and the upper box body 20 to use the elastic member to have a force on the first part 401 in the height direction, thereby ensuring the fitting of the first part 401 with the upper box body 20 and the tray 30. When the seal 41 shakes, the seal 41 can also remain in contact with the upper box body 20 and the tray 30, thereby fully sealing the gap between the upper box body 20 and the tray 30 in the height direction.

[0073] A part of an elastic member is provided between the second part 402 and the upper box body 20, so as to utilize the elastic member to apply a horizontal force to the second part 402, thereby ensuring the fitting of the second part 402 with the upper box body 20 and the tray 30. When the seal 41 shakes, the seal 41 can also remain in contact with the upper box body 20 and the tray 30, thereby sealing the gap between the upper box body 20 and the tray 30 in the height direction.

[0074] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 shown, the tray 30 is provided with a first limiting protrusion 311 and a second limiting protrusion 312. The first limiting protrusion 311 is located outside the second limiting protrusion 312. The first limiting protrusion 311 and the second limiting protrusion 312 define an annular first limiting groove 31, and the seal 41 is disposed in the first limiting groove 31.

[0075] The seal 41 has a first abutting protrusion 415 and a second abutting protrusion 416. The vehicle body assembly 1 includes a first elastic member 42. The first elastic member 42 includes a first fixing portion 421 and a first elastic portion 422. The first fixing portion 421 is fixed to the upper box body 20 and extends in the height direction. The second fixing portion 431 extends in the horizontal direction. The first elastic portion 422 abuts against the seal 41 to apply a force to the seal 41 in the height direction, so that the seal 41 abuts against the tray 30, enabling the seal 41 to fully seal the gap between the upper box body 20 and the tray 30 in the height direction.

[0076] Wherein, the second abutting protrusion 416 is located between the first fixing portion 421 and the second limiting protrusion 312, so that the first elastic member 42 applies a horizontal force to the second abutting protrusion 416 towards the second limiting protrusion 312, thereby enabling the second abutting protrusion 416 to seal the gap between the first fixing portion 421 and the second limiting protrusion 312 in the horizontal direction and sealing the gap between the upper box body 20 and the tray 30 in the horizontal direction.

[0077] In some embodiments of the present invention, such as Figure 10 , Figure 12 shown, the seal 41 is configured to be height-variable and elastically deformable, so that when the seal 41 is clamped between the upper box body 20 and the tray 30, the abutting fit between the seal 41 and the upper box body 20 can be ensured, and the abutting fit between the seal 41 and the tray 30 can be ensured, enabling the seal 41 to fully seal the gap between the upper box body 20 and the tray 30.

[0078] In some alternative embodiments of the present invention, such as Figure 10As shown, the seal 41 includes a first contact portion 51, a connecting portion 53, and a second contact portion 52. The connecting portion 53 is connected to the first contact portion 51 and the second contact portion 52 respectively. The first contact portion 51 contacts the upper box body 20, and the second contact portion 52 contacts the tray 30. The connecting portion 53 is configured to have a variable height, so that after the connecting portion 53 is squeezed, the connecting portion 53 has a force acting on the first contact portion 51 away from the second contact portion 52, and the connecting portion 53 has a force acting on the second contact portion 52 away from the first contact portion 51.

[0079] Specifically, the first contact portion 51 abuts against the tray 30, and the second contact portion 52 abuts against the upper box body 20. When the seal 41 is installed between the upper box body 20 and the tray 30, the connecting portion 53 is subjected to a squeezing force. At the same time, the connecting portion 53 has a force acting on the first contact portion 51 towards the tray 30, and the connecting portion 53 has a force acting on the second contact portion 52 towards the upper box body 20, so that the seal 41 can fully seal the gap between the upper box body 20 and the tray 30. When the seal 41 is subjected to a shaking force and has a shaking amplitude, it can also continue to ensure sufficient abutment between the seal 41 and the tray 30, ensuring the seal between the upper box body 20 and the tray 30.

[0080] In some specific embodiments of the present invention, as Figure 12 shown, at least a part of the connecting portion 53 is an inclined portion extending obliquely, so that when the connecting portion 53 is subjected to a squeezing force, the connecting portion 53 has a tendency to elastically deform in the height direction, and thus has a force acting on the first contact portion 51 away from the second contact portion 52, and the connecting portion 53 has a force acting on the second contact portion 52 away from the first contact portion 51.

[0081] In some embodiments, by controlling the angle between the extending direction of the connecting portion 53 and the horizontal direction, the degree of elastic deformation that the connecting portion 53 can undergo can be controlled, and the magnitudes of the forces exerted by the connecting portion 53 on the first contact portion 51 and the second contact portion 52 can be controlled.

[0082] In some specific embodiments of the present invention, as Figure 10 shown, at least a part of the connecting portion 53 is a cavity portion provided with a cavity 531, so that when the connecting portion 53 is subjected to a squeezing force, the connecting portion 53 has a tendency to elastically deform in the height direction, and thus the connecting portion 53 has a force acting on the first contact portion 51 away from the second contact portion 52, and the connecting portion 53 has a force acting on the second contact portion 52 away from the first contact portion 51.

[0083] In some specific embodiments of the present invention, the seal 41 is an integrally formed part.

[0084] In some examples, the seal 41 is a rubber part so that the seal 41 can undergo elastic deformation, and then the gap between the upper box body 20 and the tray 30 can be fully sealed by the seal 41.

[0085] In some embodiments of the present invention, the seal 41 is clamped between the upper box body 20 and the tray 30 to seal the gap between the upper box body 20 and the tray 30, reducing the possibility that dust, liquid, etc. may enter the accommodation cavity, so as to protect the components in the accommodation cavity.

[0086] In some embodiments of the present invention, as Figure 4 shown, the vehicle body assembly 1 further includes at least one elastic member. The seal 41 is in contact with the upper box body 20 and the tray 30 respectively. An elastic member is provided between at least one of the upper box body 20 and the tray 30 and the seal 41. The elastic member can be elastically deformed, so that the elastic member has a force acting on the seal 41 towards the upper box body 20 and / or the tray 30, so that the seal 41 can fully close the gap between the upper box body 20 and the tray 30, reducing the possibility that water or dust and other objects will enter the accommodation cavity, so as to fully protect the components in the accommodation cavity.

[0087] In some alternative embodiments of the present invention, the elastic member is a metal part. A part of the elastic member is bent so that the elastic member can be elastically deformed, and then the elastic member itself has an elastic force acting on the upper box body 20 and / or the tray 30 to ensure the abutting fit between the seal 41 and the upper box body 20 and / or the tray 30, and then the seal 41 can fully close the gap between the upper box body 20 and the tray 30.

[0088] In some specific embodiments of the present invention, as Figure 7 shown, the vehicle body assembly 1 includes a first elastic member 42. One end of the first elastic member 42 is fixed to the upper box body 20, and the other end abuts against the seal 41, so as to have a force acting on the seal 41 towards the tray 30, and then the seal 41 can fully abut against the tray 30.

[0089] Specifically, when the vehicle shakes, the seal 41 has a tendency to move relative to the tray 30 after being subjected to force. Using the force of the first elastic member 42 acting on the seal 41 towards the tray 30, the seal 41 can always be kept in contact with the tray 30. In this way, when the seal 41 shakes, the abutting fit between the tray 30 and the seal 41 can also be maintained, so that the seal 41 can close the gap between the tray 30 and the upper box body 20, reducing the possibility that water or dust and other objects will enter the accommodation cavity, and then fully protecting the components in the accommodation cavity.

[0090] In some embodiments, as Figure 6As shown, after being bent, the first elastic member 42 defines a first fixing portion 421 and a first elastic portion 422 with different extending directions. In this way, when the first elastic member 42 is disposed between the seal member 41 and the upper box body 20, after the first elastic member 42 is squeezed, the first elastic portion 422 can have a force acting towards the tray 30, and then exert a force acting towards the tray 30 on the seal member 41, so that the seal member 41 and the tray 30 are fully abutted. When the seal member 41 is subjected to a shaking force and has a shaking amplitude, the full abutment between the seal member 41 and the tray 30 can still be ensured.

[0091] In some examples, as Figure 6 shown, the tray 30 is fixed below the upper box body 20. The first fixing portion 421 extends in the height direction, and the first elastic portion 422 extends in the horizontal direction (it should be understood here that the above direction definition is only for facilitating the description of the drawings and will not limit the actual installation position and direction of the vehicle body assembly 1). The first elastic portion 422 is located above the seal member 41 and has a downward force on the seal member 41, so that the seal member 41 and the tray 30 are fully abutted. When the seal member 41 is subjected to a shaking force and has a shaking amplitude, the full abutment between the seal member 41 and the tray 30 can still be ensured.

[0092] In some examples, the first fixing portion 421 is fixedly connected to the inner wall of the side wall of the upper box body 20.

[0093] Specifically, the first fixing portion 421 is fixedly connected to the side wall of the upper box body 20 by welding.

[0094] In some embodiments, as Figure 7 shown, the upper wall surface of the seal member 41 abuts against the first elastic portion 422. The first elastic member 42 has a force acting towards the tray 30 on the seal member 41, so that the seal member 41 and the tray 30 are fully abutted. When the seal member 41 is subjected to a shaking force and has a shaking amplitude, the full abutment between the seal member 41 and the tray 30 can still be ensured.

[0095] In some examples, as Figure 8 shown, the lower wall surface of the seal member 41 defines a positioning groove 413, and the tray 30 is provided with a positioning block 32. The positioning block 32 extends into the positioning groove 413 to cooperate with the positioning groove 413, thereby limiting the position of the seal member 41.

[0096] In some specific embodiments of the present invention, as Figure 9 shown, the vehicle body assembly 1 further includes a second elastic member 43. One end of the second elastic member 43 is fixed to the tray 30, and the other end abuts against the seal member 41, so as to have a force acting towards the upper box body 20 on the seal member 41, and then enable the seal member 41 to fully abut against the upper box body 20.

[0097] Specifically, when the vehicle shakes and the seal 41 is subjected to a force and has a tendency to move relative to the upper box body 20, the second elastic member 43 has a force acting on the seal 41 towards the upper box body 20, which can keep the seal 41 in contact with the upper box body 20 all the time. In this way, when the seal 41 shakes, the abutting fit between the upper box body 20 and the seal 41 can also be maintained, so that the seal 41 can seal the gap between the tray 30 and the upper box body 20, thereby reducing the possibility of water or dust and other objects entering the accommodation cavity, and further fully protecting the components in the accommodation cavity.

[0098] In some embodiments, as Figure 6 shown, after the second elastic member 43 is bent, a second fixing portion 431 and a second elastic portion 432 with different extending directions are defined. In this way, when the second elastic member 43 is arranged between the seal 41 and the tray 30, after the second elastic member 43 is subjected to a squeezing force, the second elastic portion 432 can have a force acting on the upper box body 20, and then exert a force on the seal 41 towards the upper box body 20, so that the seal 41 abuts against the upper box body 20 sufficiently. When the seal 41 is subjected to a shaking force and has a shaking amplitude, the sufficient abutment between the seal 41 and the upper box body 20 can still be ensured.

[0099] In some examples, as Figure 6 shown, the tray 30 is fixed below the upper box body 20. The second fixing portion 431 extends in the horizontal direction. The second elastic portion 432 is an arc-shaped elastic portion, and the arc-shaped elastic portion bends in the direction away from the tray 30. The second elastic portion 432 is located below the seal 41 and has an upward force on the seal 41, so that the seal 41 abuts against the upper box body 20 sufficiently. When the seal 41 is subjected to a shaking force and has a shaking amplitude, the sufficient abutment between the seal 41 and the upper box body 20 can still be ensured.

[0100] In some examples, the second fixing portion 431 is fixedly connected to the tray 30 by welding.

[0101] In some alternative embodiments of the present invention, the seal 41 is provided with a receiving groove for receiving the elastic member to limit the position of the elastic member, so that the elastic member can cooperate with the seal 41, and then exert a force on the seal 41, so that the seal 41 can sufficiently seal the gap between the tray 30 and the upper box body 20, thereby reducing the possibility of water or dust and other objects entering the accommodation cavity, and further fully protecting the components in the accommodation cavity.

[0102] In some embodiments, as Figure 6As shown, the vehicle body assembly 1 further includes a first elastic member 42. A first receiving groove 411 is defined in the seal member 41. A part of the first elastic member 42 extends into the first receiving groove 411 and abuts against the bottom wall of the first receiving groove 411. The side wall of the first receiving groove 411 can limit the position of the first elastic member 42 to ensure the abutting fit between the first elastic member 42 and the bottom wall of the first receiving groove 411. Furthermore, the first elastic member 42 applies a force towards the tray 30 to the seal member 41, causing the seal member 41 to fully abut against the tray 30. When the seal member 41 is subjected to a shaking force and has a shaking amplitude, the full abutment between the seal member 41 and the tray 30 can still be ensured.

[0103] In some examples, as Figure 6 shown, the seal member 41 includes a first abutting protrusion 415 and a second abutting protrusion 416. The first abutting protrusion 415 and the second abutting protrusion 416 define an annular first receiving groove 411. A part of the first elastic member 42 extends into the first receiving groove 411. The first abutting protrusion 415 and the second abutting protrusion 416 can limit the fitting position of the first elastic member 42 and the seal member 41. Furthermore, the first elastic member 42 stably applies a force towards the tray 30 to the seal member 41, causing the tray 30 and the seal member 41 to come into contact, so that the seal member 41 can fully seal the gap between the tray 30 and the upper box body 20.

[0104] Furthermore, the first abutting protrusion 415 is located outside the second abutting protrusion 416. The first elastic member 42 includes a first fixing portion 421 and a first elastic portion 422. The first fixing portion 421 extends in the height direction, and the first elastic portion 422 extends in the horizontal direction. The first elastic portion 422 abuts against the bottom wall of the first receiving groove 411 to apply a force towards the tray 30 to the seal member 41.

[0105] Wherein, one of the first abutting protrusion 415 and the second abutting protrusion 416 abuts and cooperates with the first fixing portion 421 to further seal the gap between the seal member 41 and the first elastic member 42, further reducing the possibility that liquids, dust, and other objects will enter the receiving cavity, and thus fully protecting the components in the receiving cavity.

[0106] In some examples, the first abutting protrusion 415 extends beyond the part where the first elastic member 42 abuts against the first receiving groove 411. In this way, when there is an impact on the vehicle body assembly 1 from the outside by liquid, the first abutting protrusion 415 can limit the flow of the liquid to the gap between the first elastic member 42 and the first receiving groove 411, further reducing the possibility that the liquid will enter the receiving cavity, and thus fully protecting the components in the receiving cavity.

[0107] In some examples, as Figure 6As shown, the top of the first abutting protrusion 415 and the upper box body 20 are arranged in the height direction and abut against each other. The second abutting protrusion 416 and the first fixing portion 421 are arranged in the horizontal direction and abut against each other, so as to fully seal the gap between the upper box body 20 and the tray 30, reduce the possibility that liquid, dust and other objects enter the accommodation cavity, and thus fully protect the components in the accommodation cavity.

[0108] Further, a first guiding surface 417 is provided on the side of the second abutting protrusion 416 facing the first fixing portion 421. In the downward direction, the first guiding surface 417 extends obliquely towards the direction close to the first fixing portion 421. That is to say, after the seal 41 is arranged on the tray 30 and the tray 30 is installed on the upper box body 20 from bottom to top, the gap between the second abutting protrusion 416 and the first fixing portion 421 is relatively large at the beginning, so as to facilitate at least part of the first fixing portion 421 to extend into the first accommodation groove 411, and smoothly abut and cooperate with the second abutting protrusion 416 under the guidance of the first guiding surface 417.

[0109] In some embodiments, as Figure 6 shown, the seal 41 includes a second elastic member 43. A second accommodation groove 412 is defined on the seal 41. A part of the second elastic member 43 extends into the second accommodation groove 412 and abuts against the bottom wall of the second accommodation groove 412. The side wall of the second accommodation groove 412 can limit the position of the second elastic member 43 to ensure the abutting cooperation between the second elastic member 43 and the bottom wall of the second accommodation groove 412. Furthermore, the second elastic member 43 is used to apply a force towards the upper box body 20 to the seal 41, so that the seal 41 fully abuts against the upper box body 20. When the seal 41 is subjected to a shaking force and has a shaking amplitude, the full abutment between the seal 41 and the upper box body 20 can still be ensured.

[0110] In some alternative embodiments of the present invention, at least one of the upper box body 20 and the tray 30 is provided with a limiting groove for limiting the seal 41 to limit the position of the seal 41 and prevent it from moving when the seal 41 is subjected to a force, which affects the sealing performance of the gap between the seal 41 and the upper box body 20 and the tray 30.

[0111] In some specific embodiments of the present invention, as Figure 4 shown, the limiting groove is defined by a first limiting protrusion 311 and a second limiting protrusion 312 which are arranged at intervals. At least a part of the seal 41 is located in the limiting groove to limit the position of the seal 41 and prevent it from moving when the seal 41 is subjected to a force, which affects the sealing performance of the gap between the seal 41 and the upper box body 20 and the tray 30.

[0112] In some alternative embodiments of the present invention, as Figures 10 - 13As shown, the limiting groove includes limiting surfaces oppositely arranged in the height direction. At least a part of the seal 41 is located in the limiting groove and contacts the oppositely arranged limiting surfaces to seal the gap between the seal 41 and the tray 30.

[0113] In some embodiments, on the side of the tray 30 facing the seal 41, a first limiting protrusion 311 and a second limiting protrusion 312 are arranged at intervals in the horizontal direction. The first limiting protrusion 311 and the second limiting protrusion 312 define a first limiting groove 31. The bottom wall of the first limiting groove 31 defines a limiting surface. The first contact portion 51 extends into the first limiting groove 31 and is adapted to contact the bottom of the first limiting groove 31.

[0114] In some examples, the first limiting protrusion 311 includes a first protrusion 3111 and a first flanging 3112. The second limiting protrusion 312 includes a second protrusion 3121 and a second flanging 3122. The sides of the first flanging 3112 and the second flanging 3122 facing each other extend obliquely in the height direction away from the upper box body 20 and towards each other. The sides of the first contact portion 51 on both sides in the horizontal direction extend obliquely in the height direction away from the upper box body 20 and towards each other to facilitate the entry of the first contact portion 51 into the first limiting groove 31 and at the same time reduce the possibility of the first contact portion 51 coming out of the first limiting groove 31.

[0115] In some embodiments, as Figure 11 、 Figure 13 shown, on the side of the upper box body 20 facing the seal 41, a third limiting protrusion 313 and a fourth limiting protrusion 314 are arranged in the horizontal direction. The third limiting protrusion 313 and the fourth limiting protrusion 314 define a second limiting groove. The bottom wall of the second limiting groove defines a limiting surface. The second contact portion 52 extends into the second limiting groove and is adapted to contact the bottom of the second limiting groove.

[0116] In some examples, the third limiting protrusion 313 includes a third protrusion and a third flanging. The fourth limiting protrusion 314 includes a fourth protrusion and a fourth flanging. The sides of the third flanging and the fourth flanging facing each other extend obliquely in the height direction away from the upper box body 20 and towards each other. The sides of the second contact portion 52 on both sides in the horizontal direction extend obliquely in the height direction away from the upper box body 20 and towards each other to facilitate the entry of the second contact portion 52 into the second limiting groove and at the same time reduce the possibility of the second contact portion 52 coming out of the second limiting groove.

[0117] In some embodiments of the present invention, as Figure 1As shown, the upper cover 21 includes reinforcing side walls 211 arranged in the second direction, the second direction being perpendicular to the first direction. Seals 41 are provided between the two reinforcing side walls 211 and the two support beams 11 and the tray 30 respectively, so that the seals 41 can completely seal the gap between the tray 30 and the upper box body 20 in the circumferential direction, thereby reducing the possibility of dust, liquid, etc. entering the accommodation cavity, and protecting the components in the accommodation cavity.

[0118] In some alternative embodiments of the present invention, the seal 41 is formed as an integral ring structure to be able to completely seal the gap between the tray 30 and the upper box body 20 in the circumferential direction, thereby reducing the possibility of dust, liquid, etc. entering the accommodation cavity, and protecting the components in the accommodation cavity.

[0119] In some embodiments of the present invention, it further includes a battery assembly 60. The battery assembly 60 is arranged in the accommodation cavity. That is to say, the installation position of the battery assembly 60 can make full use of the space between the two support beams 11, which is convenient for improving the utilization rate of the space in the vehicle body assembly 1.
