[0054] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] The vehicle according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0056] Reference Figures 1-13 According to an embodiment of the present invention, the vehicle includes a body, a battery pack 2, and an electrical connection assembly 3. The battery pack 2 is mounted on the underside of the body, and the electrical connection assembly 3 is used to electrically connect the battery pack 2 to the vehicle's electrical components. For example, the vehicle may be an electric vehicle.

[0057] The vehicle body includes a frame beam 11, which encloses a mounting cavity 12. For example, the frame beam 11 may include a left beam 101, a right beam 102, a front beam 103, and a rear beam 104. The left beam 101 and the right beam 102 may be arranged opposite each other and spaced apart in the left-right direction, and both the left beam 101 and the right beam 102 extend in the front-rear direction. The front beam 103 and the rear beam 104 may be arranged opposite each other and spaced apart in the front-rear direction, and both the front beam 103 and the rear beam 104 extend in the left-right direction. The left end of the front beam 103 is connected to the front end of the left beam 101, and the right end of the front beam 103 is connected to the front end of the right beam 102. The left end of the rear beam 104 is connected to the rear end of the left beam 101, and the right end of the rear beam 104 is connected to the rear end of the right beam 102. The mounting cavity 12 is defined between the left beam 101, the right beam 102, the front beam 103, and the rear beam 104. The left beam 101, right beam 102, front beam 103 and rear beam 104 can be welded together, and after being welded together, they can form an installation cavity 12.

[0058] At least one layer of battery pack 2 is disposed in the mounting cavity 12. It can be that only one layer of battery pack 2 is disposed in the mounting cavity 12, or multiple layers of battery pack 2 are disposed in the mounting cavity 12. The battery pack 2 is fixed to the vehicle frame beam 11. This can make full use of the vehicle frame beam 11 and the space inside the vehicle frame beam 11. By fixing the battery pack 2 inside the vehicle frame beam 11, the battery pack shell used for packaging the battery cells 21 can be eliminated, redundant sealing is avoided, and the space utilization rate of the vehicle frame beam 11 is improved.

[0059] The electrical connection assembly 3 is used to electrically connect the battery pack 2 to the vehicle's electrical components, enabling the battery pack 2 to provide power support for the vehicle's operation. The electrical connection assembly 3 is located on the frame beam 11, utilizing the space of the frame beam 11 to fix the battery connection assembly and also improving the space utilization of the frame beam 11.

[0060] According to the vehicle of the present invention, by installing the battery pack 2 into the mounting cavity 12 defined by the frame beam 11 of the vehicle body, and installing the electrical connection assembly 3 for electrically connecting the battery pack 2 and the electrical devices of the vehicle into the frame beam 11, the frame beam 11 and the space within the frame beam 11 can be fully utilized to realize the installation of the battery pack 2 and the electrical connection assembly 3, thereby improving the space utilization rate of the frame beam 11; and, the battery pack housing in related technologies can be eliminated, thereby reducing the number of components, simplifying the structure, and avoiding design redundancy problems.

[0061] According to some embodiments of the present invention, with reference to Figures 1-6 as well as Figures 9-13 A hollow cavity 15 is formed inside the beam of the frame beam 11. The electrical connection component 3 is built into the hollow cavity 15, which can achieve the sealing of the electrical connection component 3. Moreover, the electrical connection component 3 does not occupy the external space of the beam of the frame beam 11, making full use of the internal space of the beam of the frame beam 11 and improving the space utilization rate of the frame beam 11.

[0062] According to some optional embodiments of the present invention, refer to Figures 1-6 as well as Figures 9-13 The hollow cavity 15 includes an exhaust channel 153. The battery pack 2 has an explosion-proof valve 213. The exhaust channel 153 is used to receive the emissions discharged by the battery pack 2 through the explosion-proof valve 213. By placing the exhaust channel 153 inside the hollow cavity 15, the exhaust channel 153 can be made to not occupy the external space of the frame beam 11, making full use of the internal space of the frame beam 11 and further improving the space utilization rate of the frame beam 11.

[0063] According to some optional embodiments of the present invention, refer to Figures 1-6 as well as Figures 9-13The frame beam 11 has an exhaust port 1531 that connects the exhaust passage 153 to the external environment. An exhaust valve 1532 is provided at the exhaust port 1531 for opening and closing the exhaust port 1531. When the pressure of the exhaust material in the exhaust passage 153 is greater than the pressure of the external environment, the exhaust valve 1532 can open the exhaust port 1531, and the exhaust material can be released into the external environment in an orderly manner from the exhaust port 1531. When the pressure of the exhaust material in the exhaust passage 153 is equal to or less than the pressure of the external environment, the exhaust valve 1532 can close the exhaust port 1531, which can prevent foreign objects in the external environment from entering the exhaust passage 153 through the exhaust port 1531 and damaging the explosion-proof valve 213 of the battery pack 2.

[0064] According to some optional embodiments of the present invention, refer to Figures 1-6 as well as Figures 9-13 The electrical connection assembly 3 includes a distribution box 31, the space where the distribution box 31 is located is isolated from the exhaust channel 153, for example, the space where the distribution box 31 is located and the exhaust channel 153 can be isolated by a partition 1513. When the battery pack 2 experiences thermal runaway, it can prevent the emissions in the exhaust channel 153 from coming into contact with the distribution box 31, thus preventing the distribution box 31 from experiencing a high-voltage short circuit.

[0065] According to some optional embodiments of the present invention, refer to Figures 1-6 The distribution box 31 and the exhaust channel 153 can be located on the same side of the mounting cavity 12. For example, the exhaust channel 153 can be located below the distribution box 31, which makes the structure of the distribution box 31 and the exhaust channel 153 compact.

[0066] According to some optional embodiments of the present invention, refer to Figures 9-13 The electrical distribution box 31 and the exhaust channel 153 can also be located on different sides of the mounting cavity 12. For example, the electrical distribution box 31 can be located inside the front beam 103 of the frame beam 11, and the exhaust channel 153 can be located inside the left beam 101 or the right beam 102 of the frame beam 11. The electrical distribution box 31 and the exhaust channel 153 can make full use of the space of the frame beam 11, thereby improving the space utilization rate of the frame beam 11.

[0067] According to some optional embodiments of the present invention, refer to Figures 1-13 The space where the electrical connection component 3 is located is isolated from the exhaust passage 153. The space where the electrical connection component 3 is located can be isolated from the exhaust passage 153 by using the frame beam 11. For example, the space where the electrical connection component 3 is located can be isolated from the exhaust passage 153 by using the partition 1513. This can physically isolate the exhaust passage 153 from the space where the electrical connection component 3 is located, and can avoid the risk of the emissions from the battery pack 2 coming into contact with the electrical connection component 3 when the battery pack 2 experiences thermal runaway, which could lead to a high-voltage short circuit in the electrical connection component 3.

[0068] According to some embodiments of the present invention, with reference to Figures 1-13 Limiting grooves 14 are formed on the inner sidewalls of the frame beam 11 along the first direction (e.g., the left and right direction in the attached figure). The limiting grooves 14 are connected to the mounting cavity 12. The two ends of the battery pack 2 along the first direction are accommodated in the limiting grooves 14. For example, the first direction is parallel to the horizontal direction. The limiting grooves 14 can limit the two ends of the battery pack 2 along the first direction, thereby limiting the battery pack 2. The limiting grooves 14 can also support the two ends of the battery pack 2 along the first direction, thereby supporting and limiting the battery pack 2. The battery pack 2 can be installed and fixed in the mounting cavity 12.

[0069] According to some optional embodiments of the present invention, refer to Figures 1-13 The battery pack 2 includes a plurality of battery cells 21 arranged along a second direction (e.g., the front-to-back direction in the accompanying drawings). For example, each battery cell 21 may include one or more cells. Each battery cell 21 extends along a first direction, and the opposite ends of each battery cell 21 along the first direction are accommodated in a limiting groove 14. The second direction is perpendicular to the first direction. The limiting groove 14 can limit the opposite ends of each battery cell 21 along the first direction. The limiting groove 14 can also support the opposite ends of each battery cell 21 along the first direction, thereby providing support and limiting for the battery pack 2, and can install and fix the battery pack 2 in the mounting cavity 12.

[0070] According to some optional embodiments of the present invention, refer to Figures 1-13 The battery cell 21 includes a battery body 211 and a terminal post 212. The terminal post 212 is connected to at least one side of the battery body 211 along a first direction. The terminal post 212 can be connected to one side of the battery body 211 along the first direction, or it can be connected to opposite sides of the battery body 211 along the first direction. Both opposite ends of the battery body 211 along the first direction can be accommodated in a limiting groove 14. The sidewall of the limiting groove 14 facing the mounting cavity 12 in the first direction is a supporting sidewall 13. The supporting sidewall 13 can limit the relative ends of the battery body 211 along the first direction. The supporting sidewall 13 has a supporting hole 131 through which the terminal post 212 passes. The supporting hole 131 can support the terminal post 212. The limiting groove 14 and the supporting hole 131 can limit and support the battery pack 2, thereby fixing the battery pack 2 within the mounting cavity 12.

[0071] According to some optional embodiments of the present invention, refer to Figures 1-13A sealing gasket 4 is provided between the battery body 211 and the supporting side wall 13. The sealing gasket 4 has a clearance hole 43 for avoiding the terminal post 212, which passes through the clearance hole 43. The sealing gasket 4 seals the gap between the battery body 211 and the supporting side wall 13. The sealing gasket 4 can have suitable compression properties, thereby giving it good sealing performance. The sealing gasket 4 is an insulating component, which can physically isolate the battery body 211 from the vehicle frame beam 11, thus preventing high-voltage short circuits in the battery pack 2.

[0072] According to some optional embodiments of the present invention, refer to Figures 5-6 The sealing gasket 4 includes a sealing gasket body 41 and a sealing flange 42. The sealing flange 42 can be connected to the sealing gasket body 41. The sealing gasket body 41 has a clearance hole 43. The sealing flange 42 is formed on the side of the clearance hole 43 opposite to the battery body 211. The sealing flange 42 is formed as an annular ring around the outer periphery of the clearance hole 43. The sealing flange 42 is sleeved on the outer periphery of the terminal post 212. At least a portion of the sealing flange 42 is located between the terminal post 212 and the inner wall of the support hole 131. It can be that a part of the sealing flange 42 is located between the terminal post 212 and the inner wall of the support hole 131, or the entire sealing flange 42 is located between the terminal post 212 and the inner wall of the support hole 131. The sealing gasket body 41 is used to seal the gap between the battery body 211 and the supporting side wall 13 and to physically isolate the battery body 211 from the frame beam 11. The sealing flange 42 can be used to seal the gap between the terminal post 212 and the inner peripheral wall of the supporting hole 131, and can also achieve insulation separation between the terminal post 212 and the frame beam 11. By setting the sealing gasket 4 between the battery pack 2 and the frame beam 11, the battery pack 2 and the frame beam 11 can be sealed, and the battery pack 2 and the frame beam 11 can be physically isolated, which can prevent the battery pack 2 from experiencing a high-voltage short circuit.

[0073] According to some optional embodiments of the present invention, refer to Figures 1-13 The frame beam 11 has a hollow cavity 15 inside, and the electrical connection component 3 is built into the hollow cavity 15. The electrical connection component 3 can be sealed in the hollow cavity 15, isolating the electrical connection component 3 from the rest of the battery pack 2, thus avoiding the risk of high voltage short circuit of the electrical connection component 3. This allows the electrical connection component 3 to make full use of the internal space of the frame beam 11, improving the space utilization rate of the internal space of the frame beam 11.

[0074] The hollow cavity 15 includes a first hollow cavity 151, which is located on at least one side of the mounting cavity 12 along the first direction. The first hollow cavity 151 can be located on one side of the mounting cavity 12 along the first direction, or it can be located on opposite sides of the mounting cavity 12 along the first direction. The first hollow cavity 151 is located on the side of the limiting groove 14 away from the mounting cavity 12. For example, the number of limiting grooves 14 can be set to two, and the number of first hollow cavities 151 can also be set to two. The two first hollow cavities 151 can be located on opposite sides of the mounting cavity 12 along the first direction. Multiple battery cells 21 of the battery pack 2 are connected to each other via a first electrical connector 33. The first electrical connector 33 can electrically connect the terminals 212 of two adjacent battery cells 21 by welding. The first electrical connector 33 is located in the first hollow cavity 151. The electrical connection assembly 3 includes the first electrical connector 33, which can make full use of the hollow structure formed inside the frame beam 11 to seal the first electrical connector 33 inside the hollow structure of the frame beam 11, thus avoiding redundant sealing.

[0075] According to some optional embodiments of the present invention, refer to Figures 1-8 The battery cell 21 includes an explosion-proof valve 213, which is located on at least one side of the battery cell 21 along a first direction. The first hollow cavity 151 includes an exhaust channel 153. The supporting sidewall 13 has a connecting hole 133 that communicates with the exhaust channel 153. The explosion-proof valve 213 is opposite to or accommodated in the connecting hole 133. The exhaust channel 153 is used to receive the emissions discharged by the battery pack 2 through the explosion-proof valve 213. The emissions generated by the battery cell 21 can be discharged through the explosion-proof valve 213. The emissions can be discharged into the exhaust channel 153 through the connecting hole 133, so that the exhaust channel 153 can receive the emissions and allow the emissions generated by the battery cell 21 to be released into the external environment in an orderly manner through the exhaust hole 1531.

[0076] According to some optional embodiments of the present invention, refer to Figures 1-9 A partition 1513 is provided inside the first hollow cavity 151 to divide the first hollow cavity 151 into a first cavity 1511 and a second cavity 1512 that are isolated from each other. The first electrical connector 33 is located in the first cavity 1511, and the second cavity 1512 forms an exhaust passage 153. The partition 1513 can isolate the first cavity 1511 and the second cavity 1512, thereby isolating the first electrical connector 33 from the exhaust passage 151, avoiding the risk of high-voltage short circuit of the first electrical connector 33, and also improving the space utilization of the frame beam 11.

[0077] According to some optional embodiments of the present invention, refer to Figures 1-9The explosion-proof valve 213 of the same layer battery pack 2 is located below the terminal post 212, and the second cavity 1512 is located below the first cavity 1511. That is, the exhaust channel 153 is located below the first cavity 1511. Based on the position of the explosion-proof valve 213 of the battery pack 2 and the position of the terminal post 212 of the battery pack 2, the structure of the frame beam 11 can be fully utilized, and the positions of the exhaust channel 153 and the first cavity 1511 can be reasonably arranged.

[0078] According to some optional embodiments of the present invention, refer to Figures 1-9 The electrical connection assembly 3 includes a distribution box 31, which is located within the first hollow cavity 151. This facilitates the electrical connection between the distribution box 31 and the battery pack 2, shortens the electrical connection path between them, and makes the connection structure between the battery pack 2 and the electrical connection assembly 3 more compact. By utilizing the internal space of the vehicle frame beam 11, the distribution box 31 is sealed, eliminating the need for a separate battery pack casing and avoiding redundant sealing.

[0079] According to some optional embodiments of the present invention, refer to Figures 9-13 The hollow cavity 15 includes a second hollow cavity 152, which is located on one side of the mounting cavity 12 along the second direction. The second hollow cavity 152 is isolated from the exhaust passage 153. The electrical connection assembly 3 includes a distribution box 31, which is located in the second hollow cavity 152, thus isolating the distribution box 31 from the exhaust passage 153 and avoiding the risk of high-voltage short circuit in the distribution box 31. For example, the second hollow cavity 152 can be located within the front beam 103 of the frame beam 11, which is beneficial for the maintenance of the distribution box 31.

[0080] According to some optional embodiments of the present invention, refer to Figures 1-13 The electrical connection component 3 includes a second electrical connector 32. The distribution box 31 and the battery pack 2 are electrically connected through the second electrical connector 32. By setting the second electrical connector 32, the electrical connection between the distribution box 31 and the battery pack 2 can be facilitated.

[0081] For example, in some embodiments of the present invention, when the distribution box 31 is located in the first hollow cavity 151, the second electrical connector 32 can also be located in the first hollow cavity 151. The second electrical connector 32 can electrically connect the distribution box 31 and the battery pack 2, which can facilitate the second electrical connector 32 to electrically connect the battery pack 2 and the distribution box 31, shorten the size of the second electrical connector 32, make the structure of the second electrical connector 32 more compact, and simplify the design of the electrical connection assembly 3.

[0082] For example, in some other embodiments of the present invention, when the distribution box 31 is located in the second hollow cavity 152, part of the second electrical connector 32 is located in the first hollow cavity 151 and the other part of the second electrical connector 32 is located in the second hollow cavity 152. The distribution box 31 and the battery pack 2 are electrically connected through the second electrical connector 32, which facilitates the electrical connection between the battery pack 2 and the distribution box 31. The fact that the distribution box 31 is located in the second hollow cavity 152 also facilitates the later maintenance and replacement of the distribution box 31.

[0083] According to some optional embodiments of the present invention, the vehicle further includes a first temperature regulating plate for regulating the temperature of the battery pack 2. The first temperature regulating plate can be used for heating or cooling the battery pack 2, for example, the first temperature regulating plate can be a liquid cooling plate. The first temperature regulating plate is disposed in the first hollow cavity 151 and is thermally connected to the first electrical connector 33. For example, a first thermally conductive adhesive layer is applied between the first electrical connector 33 and the first temperature regulating plate, which can fix the first temperature regulating plate to the first electrical connector 33. When the battery pack 2 is working, a lot of heat is generated at the first electrical connector 33. By setting the first temperature regulating plate to be thermally connected to the first electrical connector 33, the heat dissipation efficiency of the first temperature regulating plate to the first electrical connector 33 can be improved.

[0084] According to some optional embodiments of the present invention, refer to Figures 9-13 The thickness of the battery cell 21 extends along the height of the vehicle. Given a fixed number of battery cells 21 in the vehicle, extending the thickness of the battery cell 21 along the vehicle's height reduces the overall thickness of the battery pack along the vehicle's height, thus increasing the distance between the battery pack 2 and the ground. When the vehicle is traveling on the road, this reduces the probability of road obstacles scraping the battery pack 2, thereby improving its safety performance.

[0085] According to some embodiments of the present invention, with reference to Figures 9-13 The battery pack 2 is a multi-layered structure arranged vertically. Each layer of the battery pack 2 includes multiple battery cells 21. Each battery cell 21 extends along a first direction and includes a battery body 211 and a terminal post 212. The terminal post 212 is connected to at least one side of the battery body 211 along the first direction. Alternatively, the terminal post 212 can be connected to only one side of the battery body 211 along the first direction, or it can be connected to opposite sides of the battery body 211 along the first direction. The multiple battery cells 21 in each layer of the battery pack 2 are arranged along a second direction, which is perpendicular to the first direction. For example, the second direction and the first direction are both parallel to the horizontal direction. The electrical connection assembly 3 includes a distribution box 31, which is located on one side of the multi-layered battery pack 2 along the second direction.

[0086] For example, the distribution box 31 is located on one side of the multi-layer battery pack 2 along the second direction, which allows the two second electrical connectors 32 to be connected to the same side of the distribution box 31, thus simplifying the design of the distribution box 31; the distribution box 31 can be located inside the front beam 103 of the frame beam 11, which is also beneficial for the maintenance of the distribution box 31.

[0087] According to some embodiments of the present invention, with reference to Figures 1-6 The vehicle also includes a second temperature regulating plate 5 for regulating the temperature of the battery pack 2. The second temperature regulating plate 5 can be used for heating or cooling the battery pack 2; for example, the second temperature regulating plate 5 can be a liquid cooling plate. The second temperature regulating plate 5 is stacked on top of the battery pack 2 in the vertical direction and is thermally connected to the battery pack 2, which can increase the contact area between the second temperature regulating plate 5 and the battery pack 2. A second thermally conductive adhesive layer 6 can be applied between the second temperature regulating plate 5 and the battery pack 2. The second thermally conductive adhesive layer 6 can fix the second temperature regulating plate 5 to the battery pack 2 and can also improve the heating or heat dissipation efficiency of the second temperature regulating plate 5 for the battery pack 2. When the temperature of the battery pack 2 is too high, the heat of the battery pack 2 can be quickly transferred to the second temperature regulating plate 5 through the second thermally conductive adhesive layer 6, and the second temperature regulating plate 5 can transfer the heat of the battery pack 2 to the external environment for heat dissipation. When the temperature of the battery pack 2 is too low, the heat of the second temperature regulating plate 5 can be quickly transferred to the battery pack 2 through the second thermally conductive adhesive layer 6 for heating.

[0088] According to some optional embodiments of the present invention, refer to Figures 1-10 The second temperature regulating plate 5 has a heat exchange channel for the flow of a heat exchange medium, which can be a liquid, such as water. The second temperature regulating plate 5 has a regulating plate connector 51 communicating with the heat exchange channel. The regulating plate connector 51 extends through the frame beam 11, and a through hole 16 can be provided on the frame beam 11. The regulating plate connector 51 can pass through the through hole 16 of the frame beam 11 and connect to the vehicle's thermal management system, thus making full use of the structure of the frame beam 11 and improving its utilization rate. The heat exchange medium can circulate within the heat exchange channel of the second temperature regulating plate 5 to regulate the temperature of the battery pack 2.

[0089] According to some optional embodiments of the present invention, refer to Figures 1-6 The battery pack 2 is a single layer, and the second temperature regulating plate 5 is located on the upper side of the battery pack 2. This provides some protection for the battery pack 2, and the second temperature regulating plate 5 can also be used to regulate the temperature of the battery pack 2. (Refer to...) Figures 9-13Alternatively, the battery pack 2 can be a multi-layer structure arranged vertically, with a second temperature regulating plate 5 between two adjacent battery pack layers 2. The second temperature regulating plate 5 can simultaneously regulate the temperature of the two battery pack layers 2, thereby improving the efficiency of the second temperature regulating plate 5 in regulating the temperature of the battery pack 2.

[0090] According to some embodiments of the present invention, with reference to Figures 1-13 The vehicle also includes a protective plate 7, which is located on the bottom surface of the battery pack 2 and connected to the frame beam 11. The protective plate 7 can protect the bottom surface of the battery pack 2 from damage by the external environment. Optionally, the protective plate 7 can be detachably located on the bottom surface of the frame beam 11. For example, the protective plate 7 can be connected to the frame beam 11 by fasteners, which facilitates the replacement of the protective plate 7.

[0091] Furthermore, a first insulation layer 8 can be provided between the protective plate 7 and the battery pack 2. Insulation material can be filled in the first insulation layer 8. The first insulation layer 8 can be used to insulate the battery pack 2 and prevent the heat or cold of the battery pack 2 from being lost too quickly, which is not conducive to the use of the battery pack 2.

The hollow cavity 15 includes a first hollow cavity 151, which includes a first cavity 1511 and a second cavity 1512 that are isolated from each other. A limiting groove 14 is formed at the right end of the left beam 101, and a limiting groove 14 is also formed at the left end of the right beam 102. The limiting groove 14 is a supporting sidewall 13 facing the mounting cavity 12 in a first direction (e.g., the left-right direction in the attached figure), and the supporting sidewall 13 is formed with a supporting hole 131.

[0094] The left beam 101 can be composed of a left beam body 1011, a first sealing side beam 1012, and a second sealing side beam 1013.

[0096] The battery pack 2 is disposed within the mounting cavity 12 and is arranged as a single layer. The battery pack 2 includes multiple battery cells 21 arranged along a second direction. The thickness direction of the battery cells 21 is parallel to the vertical direction. Each battery cell 21 includes a battery body 211 and an electrode post 212. The electrode post 212 is connected to the opposite ends of the battery body 211 along a first direction. The opposite ends of the battery body 211 along the first direction are accommodated in limiting grooves 14. The electrode post 212 can pass through the support holes 131 on the supporting sidewall 13. The limiting grooves 14 and the support holes 131 can provide support and limit the battery pack 2.

[0097] A sealing gasket 4 is provided between the battery body 211 and the supporting sidewall 13. The sealing gasket 4 includes a sealing gasket body 41 and a sealing flange 42.

The sealing flange 42 is located between the terminal post 212 and the inner wall of the supporting hole 131. The sealing flange 42 can be sleeved on the outer periphery of the terminal post 212. The sealing gasket 4 is used to seal the gap between the battery body 211 and the supporting sidewall 13.

[0098] The supporting sidewall 13 has a connecting hole 133. Each battery cell 21 is equipped with an explosion-proof valve 213. The sealing gasket 4 has a clearance port 44 to avoid the explosion-proof valve 213. The clearance port 44 communicates with the connecting hole 133. The explosion-proof valve 213 is opposite to or accommodated in the connecting hole 133. The exhaust channel 153 is used to receive the emissions discharged by the battery pack 2 through the explosion-proof valve 213. The sidewall of the exhaust channel 153 has an exhaust hole 1531 connecting the exhaust channel 153 with the external environment. An exhaust valve 1532 is provided at the exhaust hole 1531. When the battery pack 2 experiences thermal runaway, the emissions in the battery pack 2 are rapidly generated and accumulate in the exhaust channel 153 through the explosion-proof valve 213 of the battery pack 2. The exhaust valve 1532 can open the exhaust hole 1531 to rapidly release the emissions from the exhaust channel 153 to the external environment, preventing the battery pack 2 from exploding.

[0099] The electrical connection assembly 3 includes a distribution box 31, a first electrical connector 33, and a second electrical connector 32, all located within the first cavity 1511.

A connector 134 is formed on the supporting sidewall 13 adjacent to the distribution box 31. The distribution box 31 can be connected to a connector 35 via the third electrical connector 34. The connector 35 passes through the connector 134 and connects to the vehicle's electrical components, enabling the battery pack 2 to provide power to the vehicle. The electrical connection assembly 3 is housed within the first cavity 1511, allowing for sealing and eliminating the need for a separate battery pack casing, thus avoiding redundant sealing. The partition 1513 can physically isolate the first cavity 1511 from the exhaust channel 153. An insulating layer can be covered on the inner wall of the exhaust channel 153. The insulating layer can further physically isolate the exhaust channel 153 from the first cavity 1511, and can isolate the electrical connection component 3 from the explosion-proof valve 213 of the battery pack 2, thus avoiding the risk of high-voltage short circuit in the electrical connection component 3.

The heat exchange medium may circulate within the heat exchange channel of the second temperature regulating plate 5. The second thermally conductive adhesive layer 6 may fix the second temperature regulating plate 5 to the battery pack 2 and may allow the heat or cold energy of the second temperature regulating plate 5 to be quickly transferred to the battery pack 2 to regulate the temperature of the battery pack 2. The second insulation layer may be located between the battery pack 2 and the front beam 103, or between the battery pack 2 and the rear beam 104. For example, the second insulation layer may be aerogel. The first insulation layer 8 may be located on the bottom surface of the battery pack 2. The first insulation layer 8 and the second insulation layer can also keep the battery pack 2 warm, preventing the battery pack 2 from losing heat or cold too quickly, which is not good for the use of the battery pack 2.

[0101] The vehicle also includes a protective plate 7, which is detachably mounted on the bottom surface of the frame beam 11. The protective plate 7 can be mounted on the bottom surface of the first insulation layer 8.
