Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle. Background Technology

[0002] With the rapid development of new energy electric vehicles, consumers have increasingly higher demands for the range of electric vehicles. This has led to larger battery capacity and size, making the battery more susceptible to damage in collisions and increasing the risk of spontaneous combustion, with potentially serious consequences. Therefore, the safety of electric vehicles will significantly impact the development of the electric vehicle industry. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, one object of this application is to provide a vehicle in which, when the vehicle is impacted, the impact force is transmitted to an energy-absorbing component and a front crossbeam. The energy-absorbing component collapses to absorb energy, thereby buffering the impact on the battery cell assembly, while the front crossbeam disperses the impact force, thereby improving the safety of the battery device.

[0004] The vehicle according to this application includes: a battery device comprising a battery cell assembly, a frame, and an energy-absorbing element, wherein a receiving cavity is formed within the frame, the battery cell assembly is located within the receiving cavity, and the energy-absorbing element is connected to the front of the frame and is adapted to collapse and absorb energy in the event of a collision with the battery device; and a vehicle body, wherein the battery device is mounted within the vehicle body, the vehicle body including a front bulkhead beam, the front bulkhead beam being located above the battery device and detachably connected to the frame, and the energy-absorbing element being located below the front bulkhead beam and detachably connected to the front bulkhead beam.

[0005] According to the vehicle of this application, an energy-absorbing component is provided in front of the frame of the battery device and is connected to the front crossbeam of the vehicle body. When the vehicle is hit, the impact force is transmitted to the energy-absorbing component and the front crossbeam. The energy-absorbing component collapses to absorb energy and is used to buffer the impact of the battery cell assembly. At the same time, the front crossbeam is used to disperse the impact force, thereby improving the safety of the battery device.

[0006] In some embodiments, the energy-absorbing element has multiple cavities inside.

[0007] This embodiment incorporates multiple cavities within the energy-absorbing component. These cavities absorb impact forces and convert the kinetic energy generated by the collision into the internal energy of the energy-absorbing component's own structural deformation, thereby significantly reducing the impact force transmitted to the battery cell assembly.

[0008] In some embodiments, the vehicle body further includes a connector connected to the rear end of the front bulkhead crossbeam and connected to the battery assembly.

[0009] This embodiment uses a connector between the rear end of the front crossbeam and the battery device to connect the front crossbeam and the battery device, thereby further increasing the connection strength between the battery device and the vehicle body. When the vehicle is hit, the front crossbeam and the battery device are an integral structure, which can better resist the impact force and reduce the impact force transmitted to the battery cell assembly.

[0010] In some embodiments, the connector includes: a first step surface and a second step surface spaced apart in a front-rear direction, both the first step surface and the second step surface facing forward, and both the first step surface and the second step surface fitting against the front crossbeam.

[0011] In this embodiment, a first step surface and a second step surface spaced apart in the front-to-back direction are provided on the connector. Both the first step surface and the second step surface are in contact with the front crossbeam, so as to form two support surfaces spaced apart in the front-to-back direction between the reinforcing member and the front crossbeam, which can better support and transmit force and distribute the force.

[0012] In some embodiments, the battery device further includes: an upper cover and a central channel, the upper cover being located above the battery cell assembly and connected to the frame, the central channel being located above the upper cover, and the front of the central channel being connected to the connector.

[0013] In this embodiment, the rear end of the connector is connected to the front of the central channel. When the battery device is impacted, the impact force can be transmitted to the connector through the front crossbeam, and then to the central channel through the connector, which increases the dispersion path of the impact force. At the same time, the upper cover of the battery device is the floor of the vehicle, which saves the space above the battery device and increases the power distribution space of the battery device in the vertical direction.

[0014] In some embodiments, the battery device further includes a seat crossbeam connected to the rear end of the central channel.

[0015] In this embodiment, by connecting the central channel to the seat crossbeam, when the battery device is impacted, the impact force can be transmitted through the front crossbeam to the connector, then through the connector to the central channel, and finally through the central channel to the seat crossbeam, in order to further disperse the impact force.

[0016] In some embodiments, the central channel includes a first longitudinal beam and a second longitudinal beam spaced apart in a left-right direction. A first channel and a second channel are formed within the connector. The first longitudinal beam extends into the first channel and fits against the wall of the first channel. The second longitudinal beam extends into the second channel and fits against the wall of the second channel.

[0017] In this embodiment, by setting the connector to cover the outer surface of the middle channel, the contact area between the connector and the middle channel is increased, thereby increasing the connection strength between the connector and the middle channel.

[0018] In some embodiments, the vehicle body further includes a left sill beam and a right sill beam, and the front bulkhead crossbeam is connected to the front ends of the left sill beam and the right sill beam.

[0019] This embodiment connects the battery device to the vehicle body at both ends, making the battery device a force transmission path in a collision, which further improves the efficiency of structural force transmission and strengthens the protective capability of the battery device.

[0020] In some embodiments, the left sill beam includes a left side plate beam extending toward the battery device, and the right sill beam includes a right side plate beam extending toward the battery device. Both the left and right side plate beams are located above the battery device, and the left and right ends of the front crossbeam are respectively connected to the front of the left and right side plate beams. Both the left and right sill beams are detachably connected to the frame.

[0021] In this embodiment, by setting both the left and right sill beams above the battery device, the contact area between the left and right sill beams and the battery device is increased, thereby further increasing the structural strength of the left and right sill beams when connected to the battery device.

[0022] In some embodiments, the vehicle body further includes a seal located between the battery device and the front bulkhead crossbeam, the left side panel beam, and the right side panel beam. This embodiment, by providing a seal between the battery device and the front bulkhead crossbeam, the left side panel beam, and the right side panel beam, not only seals the vehicle body and the battery device but also acts as a buffer when the left and right side panel beams are pressed against the top cover of the battery device.

[0047] The embodiments of this application 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 this application, and should not be construed as limiting this application.

[0048] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0049] With the rapid development of new energy electric vehicles, consumers have increasingly higher requirements for the range of electric vehicles, resulting in larger battery packs in terms of capacity and size. This makes the power battery more susceptible to damage in collisions, and the power battery is prone to overheating and spontaneous combustion, with unimaginable consequences. The safety of electric vehicles is of paramount importance and affects the development of the electric vehicle industry.

[0050] Based on the above considerations, this application proposes a vehicle including a battery device and a vehicle body. The battery device is installed inside the vehicle body and includes a battery cell assembly, a frame, and an energy-absorbing component. A receiving cavity is formed within the frame, and the battery cell assembly is located within the receiving cavity. The energy-absorbing component is connected to the front of the frame. The vehicle body includes a front crossbeam, which is located above the battery device and detachably connected to the frame. The energy-absorbing component is located below the front crossbeam and detachably connected to the front crossbeam. The energy-absorbing component can collapse and absorb energy when the battery device collides, thereby buffering the impact of the collision on the battery cell assembly. At the same time, the front crossbeam is used to distribute the force, thereby improving the safety of the battery device.

[0051] For ease of explanation, the following embodiments use a vehicle 100 as an example. The vehicle 100 can be a new energy vehicle, such as a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle. A battery device 104 is installed inside the vehicle 100, and the battery device 104 can be located at the bottom, front, or rear of the vehicle 100. The battery device 104 can be used to power the vehicle 100; for example, the battery device 104 can serve as the operating power source for the vehicle 100. The vehicle 100 may also include a controller 101 and a motor 102. The controller 101 controls the battery device 104 to supply power to the motor 102, for example, to meet the power needs of the vehicle 100 during starting, navigation, and driving.

[0052] Please refer to Figure 2 and Figure 4 , Figure 2 This is a schematic diagram of the battery device 104 and the vehicle body 103 in cooperation according to some embodiments of this application. Figure 3 yes Figure 2 A top view of the battery unit 104 in conjunction with the vehicle body 103. Figure 4 yes Figure 2 A bottom view of the battery device 104 in conjunction with the vehicle body 103.

[0053] The vehicle 100 according to this application includes: a battery device 104, which includes a battery cell assembly, a frame 51, and an energy-absorbing member 60. The frame 51 has a receiving cavity, the battery cell assembly is located in the receiving cavity, and the energy-absorbing member 60 is connected to the front of the frame 51 and is adapted to collapse and absorb energy in the event of a collision with the battery device 104; and a vehicle body 103, in which the battery device 104 is installed. The vehicle body 103 includes a front crossbeam 10, which is located above the battery device 104 and is detachably connected to the frame 51. The energy-absorbing member 60 is located below the front crossbeam 10 and is detachably connected to the front crossbeam 10.

[0054] Exemplarily, vehicle 100 includes a battery unit 104 and a body 103. The battery unit 104 is installed within the body 103, and the battery cell assembly is installed within a receiving cavity formed by a frame 51, so that the frame 51 can protect the battery cell assembly. An energy-absorbing member 60 is provided in front of the frame 51, which can collapse and absorb energy in the event of a collision with the battery unit 104 to reduce the impact on the battery cell assembly and protect the battery unit 104. For example, the energy-absorbing member 60 can be an energy-absorbing box.

[0055] Optionally, the energy-absorbing component 60 can be connected to the front of the entire frame 51; alternatively, the energy-absorbing component 60 can be connected to the front of a portion of the frame 51.

[0056] The front crossbeam 10 of vehicle 100 serves to support the front structural components of vehicle 100, playing a crucial role in the collision safety of vehicle 100 and the rigidity of vehicle body 103. An energy-absorbing component 60 is connected to the lower part of the front crossbeam 10 and is detachably connected to it to improve the structural strength and stability of the energy-absorbing component 60 during a collision, further enhancing its protective capabilities. When the battery device 104 is impacted, the force can be transferred to the front crossbeam 10 of vehicle body 103 to disperse the force on the battery device 104, thereby improving the safety of the battery device 104.

[0057] When the vehicle 100 is hit from the front, the impact force is transmitted to the energy-absorbing component 60 and the front crossbeam 10. The energy-absorbing component 60 collapses to absorb energy and cushion the impact on the battery cell assembly. At the same time, the front crossbeam 10 is used to disperse the force and transmit the force to the front crossbeam 10 of the vehicle body 103 to disperse the force on the battery device 104, thereby improving the safety of the battery device 104.

[0058] In a specific example, frame 51 may include a left beam 511, a right beam 512 and a front beam 513. The left beam 511 is located on the left side of the battery cell assembly, the right beam 512 is located on the right side of the battery cell assembly, and the front beam 513 is located in front of the battery cell assembly. The energy-absorbing component 60 may be welded and fixed to the front beam 513.

[0059] The energy-absorbing component 60 is detachably connected to the front crossbeam 10, and the front side beam 513 is also detachably connected to the front crossbeam 10. Multiple first mounting channels 62 spaced apart in the left-right direction are provided on the energy-absorbing component 60. Correspondingly, multiple second mounting channels 11 spaced apart in the left-right direction are provided on the front crossbeam 10. The multiple first mounting channels 62 and the multiple second mounting channels 11 are one-to-one and equal in number. Multiple third mounting channels 63 are also provided in front of the multiple first mounting channels 62 of the energy-absorbing component 60. The multiple third mounting channels 63 are spaced apart in the left-right direction. Correspondingly, multiple fourth mounting channels 12 spaced apart in the left-right direction are provided on the front crossbeam 10. The multiple third mounting channels 63 and the multiple fourth mounting channels 12 are one-to-one and equal in number. Bolts 44 are used to pass through the first mounting channels 62 and the second mounting channels 11, and also through the third mounting channels 63 and the fourth mounting channels 12, to connect the energy-absorbing component 60 to the front crossbeam 10.

[0060] For example, the first installation channel 62 has three channels, the second installation channel 11 also has three channels, the third installation channel 63 has four channels, and the fourth installation channel 12 also has four channels.

[0061] Multiple fifth mounting channels 5131 spaced apart in the left-right direction are provided on the frame 51. Correspondingly, multiple sixth mounting channels 13 spaced apart in the left-right direction are provided on the front crossbeam 10. The multiple fifth mounting channels 5131 and the multiple sixth mounting channels 13 correspond one-to-one and are equal in number. The multiple fifth mounting channels 5131 and the multiple first mounting channels 62 are spaced apart in the left-right direction, and the multiple sixth mounting channels 13 and the multiple second mounting channels 11 are spaced apart in the left-right direction. Bolts 44 are used to pass through the fifth mounting channels 5131 and the sixth mounting channels 13 to connect the frame 51 and the front crossbeam 10.

[0062] For example, there are six fifth installation channels 5131 and six sixth installation channels 13. Three fifth installation channels 5131 are provided on the left and right sides of the multiple first installation channels 62 respectively, and three sixth installation channels 13 are provided on the left and right sides of the multiple second installation channels 11 respectively.

[0063] According to the vehicle 100 of this application, an energy-absorbing component 60 is provided in front of the frame 51 of the battery device 104, and the energy-absorbing component 60 is connected to the front crossbeam 10 of the vehicle body 103. When the vehicle 100 is impacted, the impact force is transmitted to the energy-absorbing component 60 and the front crossbeam 10. The energy-absorbing component 60 collapses to absorb energy, which is used to buffer the impact of the battery cell assembly. At the same time, the front crossbeam 10 is used to disperse the impact force, thereby improving the safety of the battery device 104.

[0064] In some embodiments, such as Figures 4-8 , Figure 11 As shown, the energy-absorbing component 60 has multiple cavities 61 inside.

[0065] For example, the multiple cavities 61 in the energy absorber 60 are used to collapse and absorb energy when the battery device 104 is impacted. The cavities 61 can absorb the impact force and convert the kinetic energy generated by the impact into the internal energy of the deformation of the energy absorber 60 itself, thereby greatly reducing the impact force transmitted to the battery cell assembly.

[0066] For example, the cavity 61 can extend along the longitudinal direction of the vehicle 100. When the vehicle 100 is subjected to a frontal collision, the extension direction of the cavity 61 is consistent with the direction of the main impact force during the collision. The cavity 61 will guide the compression deformation of the energy-absorbing component 60 in the longitudinal direction to absorb the greater impact force from the front. The cross-section of the cavity 61 can be a polygon such as a triangle, rectangle, pentagon, or hexagon.

[0067] In this embodiment, multiple cavities 61 are provided inside the energy-absorbing component 60. The cavities 61 can absorb the impact force and convert the kinetic energy generated by the collision into the internal energy of the deformation of the energy-absorbing component 60 itself, thereby greatly reducing the impact force transmitted to the battery cell assembly.

[0068] In some embodiments, such as Figures 2-3 , Figure 5-8 As shown, the vehicle body 103 also includes a connector 20, which is connected to the rear end of the front crossbeam 10 and connected to the battery device 104.

[0069] For example, the connector 20 is located above the battery device 104 and is connected between the rear end of the front crossbeam 10 and the battery device 104. The connector 20 is used to increase the connection strength between the top of the battery device 104 and the front crossbeam 10, and to increase the structural strength when the battery device 104 is installed in the vehicle body 103 and connected to the vehicle body 103.

[0070] The battery unit 104 is connected to the front bulkhead crossbeam 10 at the front and at the top. Multiple connections are established between the battery unit 104 and the front bulkhead crossbeam 10 to increase the number of connections after the battery unit 104 is installed on the vehicle body 103. When the vehicle 100 is impacted, the front bulkhead crossbeam 10 and the battery unit 104 form an integrated structure, which can better resist impact forces and reduce the impact force transmitted to the individual battery cells.

[0071] In this embodiment, a connector 20 is provided between the rear end of the front crossbeam 10 and the battery device 104 to connect the front crossbeam 10 and the battery device 104, so as to further increase the connection strength between the battery device 104 and the vehicle body 103. When the vehicle 100 is impacted, the front crossbeam 10 and the battery device 104 are an integral structure, which can better resist the impact force and reduce the impact force transmitted to the battery cell assembly.

[0072] In some embodiments, such as Figure 2 , Figure 5 , Figure 11 As shown, the connector 20 includes a first step surface and a second step surface spaced apart in the front-rear direction. Both the first step surface and the second step surface are arranged facing forward and are in contact with the front crossbeam 10.

[0073] For example, the connector 20 can be a connecting frame, which has a first step surface and a second step surface facing the front crossbeam 10. The front crossbeam 10 also has a third step surface that fits against the first step surface and a fourth step surface that fits against the second step surface, which increases the connection area between the connector 20 and the front crossbeam 10. When the first step surface fits against the third step surface and when the second step surface fits against the fourth step surface, two support surfaces are formed between the reinforcing member and the front crossbeam 10 in the front-rear direction.

[0074] When the vehicle 100 is hit from the front, the impact force hits the two support surfaces from the front, and both support surfaces can withstand the impact force from the front. By forming two support surfaces between the reinforcing member and the front crossbeam 10, it is beneficial to support and transmit force. Moreover, the two support surfaces are spaced apart in the front-rear direction and the up-down direction, which can better distribute the force.

[0075] For example, a first inclined surface connects the first and second stepped surfaces, and correspondingly, a second inclined surface connects the third and fourth stepped surfaces. Both the first and second inclined surfaces extend forward at an incline in the front-back direction. The two supporting surfaces are a first supporting surface 42 and a second supporting surface 43. The first supporting surface 42 is located above and in front of the second supporting surface 43. When the first supporting surface 42 is subjected to an impact force from the front, it can disperse part of the force backward, while at the same time, part of the force is dispersed along the first and second inclined surfaces toward the second supporting surface 43.

[0076] In a specific example, refer to Figure 6 , Figure 10 The first step surface has multiple first mounting holes 23 spaced apart in the left-right direction, and the corresponding third step surface has multiple second mounting holes 14 spaced apart in the left-right direction. The number of first mounting holes 23 and second mounting holes 14 are equal and correspond one-to-one. Bolts are inserted into the first mounting holes 23 and second mounting holes 14. The second step surface has multiple third mounting holes 24 spaced apart in the left-right direction, and the corresponding fourth step surface has multiple fourth mounting holes 15 spaced apart in the left-right direction. The number of third mounting holes 24 and fourth mounting holes 15 are equal and correspond one-to-one. Bolts are inserted into the third mounting holes 24 and fourth mounting holes 15. This is used to connect the connector 20 to the front crossbeam 10.

[0077] For example, there are three first mounting holes 23 and three second mounting holes 14, and two third mounting holes 24 and two fourth mounting holes 15.

[0078] In this embodiment, a first step surface and a second step surface spaced apart in the front-to-back direction are provided on the connector 20. Both the first step surface and the second step surface are in contact with the front crossbeam 10, so that two support surfaces spaced apart in the front-to-back direction are formed between the reinforcing member and the front crossbeam 10, which can better support and transmit force and distribute the force.

[0079] In some embodiments, such as Figures 2-3 , Figure 11 As shown, the battery device 104 also includes an upper cover plate 71 and a central channel 72. The upper cover plate 71 is located above the battery cell assembly and is connected to the frame 51. The central channel 72 is located above the upper cover plate 71 and is connected to the connector 20 at the front.

[0080] For example, the top cover 71 is located above the battery cell assembly for sealing the battery cell assembly above. The rear end of the connector 20 is connected to the front of the central channel 72. When the battery assembly 104 is impacted, the impact force can be transmitted through the front crossbeam 10 to the connector 20, and then through the connector 20 to the central channel 72, thereby increasing the dispersion path of the impact force.

[0081] When the vehicle 100 is impacted, the energy-absorbing component 60 forms the first force transmission path, and the front crossbeam 10 and the connecting component 20 form the second force transmission path. The first force transmission path is located below the battery device 104, and the second force transmission path is located above the battery device 104. By combining the first and second force transmission paths, the protective capability of the battery device 104 is further enhanced.

[0082] The battery device 104 can be a cell-to-body battery, in which the battery cell assembly is directly mounted onto the mounting beam of the vehicle 100, and the upper cover 71 of the battery device 104 is integrated with the bottom plate 52 of the vehicle 100, so that the battery device 104 becomes part of the body 103, saving the space above the battery device 104 and increasing the power distribution space of the battery device 104 in the vertical direction.

[0083] A base plate 52 is provided below the battery cell assembly to seal the bottom of the battery cell assembly.

[0084] In this embodiment, the rear end of the connector 20 is connected to the front of the central channel 72. When the battery device 104 is impacted, the impact force can be transmitted to the connector 20 through the front crossbeam 10, and then to the central channel 72 through the connector 20, thereby increasing the dispersion path of the impact force. At the same time, the upper cover plate 71 of the battery device 104 is the bottom plate 52 of the vehicle 100, which saves the space above the battery device 104 and increases the power distribution space of the battery device 104 in the vertical direction.

[0085] In some embodiments, such as Figures 2-3 , Figures 5-8 As shown, the battery device 104 also includes a seat crossbeam 73, which is connected to the rear end of the central channel 72.

[0086] For example, the seat crossbeam 73 is used to mount the seat and is located above the upper cover plate 71. The rear end of the central channel 72 is connected to the seat crossbeam 73, and the front part of the central channel 72 is connected to the front bulkhead crossbeam 10 via the connector 20, forming a complete second force transmission path. When the battery device 104 is impacted, the impact force can be transmitted through the front bulkhead crossbeam 10 to the connector 20, then through the connector 20 to the central channel 72, and finally through the central channel 72 to the seat crossbeam 73 for further dispersion of the impact force.

[0087] For example, an extension plate is provided at the rear end of the central channel 72. The extension plate is located above the seat crossbeam 73 and connected to the seat crossbeam 73. The upper cover plate 71, the central channel 72 and the seat crossbeam 73 are fixedly connected by welding.

[0088] In this embodiment, by connecting the central channel 72 to the seat crossbeam 73, when the battery device 104 is impacted, the impact force can be transmitted through the front crossbeam 10 to the connector 20, then through the connector 20 to the central channel 72, and finally through the central channel 72 to the seat crossbeam 73, in order to further disperse the impact force.

[0089] In some embodiments, such as Figures 2-3 , Figures 5-8 , Figure 10 As shown, the central channel 72 includes a first longitudinal beam 721 and a second longitudinal beam 722 spaced apart in the left and right directions. A first channel 21 and a second channel 22 are formed in the connector 20. The first longitudinal beam 721 extends into the first channel 21 and is attached to the wall of the first channel 21. The second longitudinal beam 722 extends into the second channel 22 and is attached to the wall of the second channel 22.

[0090] For example, the central channel 72 extends into the connector 20, the wall of the first channel 21 covers the outer surface of the first longitudinal beam 721, and the wall of the second channel 22 covers the outer surface of the second longitudinal beam 722, in order to increase the contact area between the connector 20 and the central channel 72, thereby increasing the connection strength between the connector 20 and the central channel 72.

[0091] In a specific example, the first longitudinal beam 721 and the second longitudinal beam 722 are connected by a first connecting plate. A first mounting plate is also connected to the side of the first longitudinal beam 721 facing away from the first connecting plate, and a second mounting plate is also connected to the side of the second longitudinal beam 722 facing away from the first connecting plate. The first mounting plate, the first connecting plate, and the second mounting plate are all welded and fixed to the upper cover plate 71. The first channel 21 and the second channel 22 are connected by a second connecting plate. A third mounting plate is also connected to the side of the first channel 21 facing away from the second connecting plate, and a fourth mounting plate is also connected to the side of the second channel 22 facing away from the second connecting plate. The third mounting plate is located above the first mounting plate, the second connecting plate is located above the first connecting plate, and the fourth mounting plate is located above the second mounting plate.

[0092] Multiple fifth mounting holes 723 are provided on the first longitudinal beam 721, the second longitudinal beam 722, the first mounting plate, the first mounting plate, and the second mounting plate. The multiple fifth mounting holes 723 are spaced apart in the front-back direction. Multiple sixth mounting holes 25 are provided on the wall surface of the first channel 21, the wall surface of the second channel 22, the second mounting plate, the third mounting plate, and the fourth mounting plate. The multiple sixth mounting holes 25 are spaced apart in the front-back direction, and the number of fifth mounting holes 723 and sixth mounting holes 25 are equal and they are one to one opposite each other. Bolts 44 are passed through the fifth mounting holes 723 and the sixth mounting holes 25 to connect the mounting part 20 to the middle channel 72.

[0093] In this embodiment, by setting the connector 20 to cover the outer surface of the middle channel 72, the contact area between the connector 20 and the middle channel 72 is increased, thereby increasing the connection strength between the connector 20 and the middle channel 72.

[0094] In some embodiments, such as Figures 2-9 As shown, the vehicle body 103 includes a left sill beam 31 and a right sill beam 32. The front crossbeam 10 is connected to the front end of the left sill beam 31 and the right sill beam 32. Both the left sill beam 31 and the right sill beam 32 are detachably connected to the frame 51 of the battery device 104.

[0095] The front crossbeam 10, the left sill beam 31, and the right sill beam 32 form the front frame 51 of the vehicle 100. For example, the left sill beam 31 and the right sill beam 32 each have multiple cavities extending in the front-rear direction.

[0096] In this embodiment, by setting both ends of the battery device 104 to be connected to the vehicle body 103, the battery device 104 becomes a force transmission path in a collision, which further improves the efficiency of structural force transmission and also strengthens the protective capability of the battery device 104.

[0097] In a specific example, the left beam 511 of the battery device 104 includes a left extension 5111 extending toward the left sill beam 31, with the left sill beam 31 located above the left extension 5111. The right beam 512 includes a right extension 5121 extending toward the right sill beam 32, with the right sill beam 32 located above the right extension 5121. The left extension 5111 has a plurality of first connecting holes 5112 extending in a front-rear direction. The left sill beam 31 has a plurality of second connecting holes 312, the number of which is equal to and corresponds one-to-one with the number of first connecting holes 5112. The right extension 5121 is provided with a plurality of third connecting holes 5122, which extend in the front-to-back direction. The right sill beam 32 is provided with a plurality of fourth connecting holes 322, which are equal in number to the third connecting holes 5122 and correspond one-to-one. Bolts 44 are inserted through the first connecting hole 5112 and the second connecting hole 312, the third connecting hole 5122 and the fourth connecting hole 322, to connect the battery device 104 to the left sill beam 31 and the right sill beam 32.

[0098] In some embodiments, such as Figures 2-11 As shown, the left sill beam 31 includes a left sill beam 311 extending toward the battery device 104, and the right sill beam 32 includes a right sill beam 321 extending toward the battery device 104. Both the left sill beam 311 and the right sill beam 321 are located above the battery device 104, and the left and right ends of the front crossbeam 10 are respectively in front of the left sill beam 311 and the right sill beam 321.

[0099] In this embodiment, by setting both the left sill beam 311 and the right sill beam 321 above the battery device 104, the contact area between the left sill beam 31 and the right sill beam 32 and the battery device 104 is increased, thereby further increasing the structural strength of the left sill beam 31 and the right sill beam 32 when connected to the battery device 104.

[0100] In one specific example, the battery device 104 also includes a seat crossbeam 73, the left and right ends of which are connected to the left sill beam 31 and the right sill beam 32, respectively. The left end of the seat crossbeam 73 is connected to the left sill beam 31 via a left connecting bracket 74. One end of the left connecting bracket 74 covers the outer surface of the seat crossbeam 73, and the other end is located on the upper surface of the left sill beam 31. The left connecting bracket 74 is detachably connected to the seat crossbeam 73 and the left sill beam 31. The right end of the seat crossbeam 73 is connected to the right sill beam 32 via a right connecting bracket 75. One end of the right connecting bracket 75 covers the outer surface of the seat crossbeam 73, and the other end is located on the upper surface of the right sill beam 32. The right connecting bracket 75 is detachably connected to the seat crossbeam 73 and the right sill beam 32.

[0101] The left connecting bracket 74 is provided with multiple fifth connecting holes 741, and the left sill beam 31 is provided with multiple sixth connecting holes. The number of fifth connecting holes 741 and sixth connecting holes are equal and correspond one-to-one. Bolts 44 are used to pass through the fifth connecting holes 741 and the sixth connecting holes to connect the left connecting bracket 74 and the left sill beam 31. The left side plate beam 311 is provided with some of the sixth connecting holes.

[0102] The right connecting bracket 75 is provided with multiple seventh connecting holes 751, and the right sill beam 32 is provided with multiple eighth connecting holes. The number of seventh connecting holes 751 and eighth connecting holes are equal and correspond one-to-one. Bolts 44 are used to pass through the seventh connecting holes 751 and the eighth connecting holes to connect the left connecting bracket 74 and the left sill beam 31. The left plate beam 311 is provided with some of the eighth connecting holes.

[0103] In some embodiments, such as Figures 2-11 As shown, the vehicle body 103 also includes a seal 41, which is located between the battery device 104 and the front crossbeam 10, the left side beam 311 and the right side beam 321.

[0104] For example, the seal 41 serves to seal the connection between the vehicle body 103 and the battery device 104, acts as a buffer when the left side beam 311 is pressed against the upper cover plate 71 of the battery device 104, and acts as a buffer when the right side beam 321 is pressed against the upper cover plate 71 of the battery device 104.

[0105] For example, seal 41 is a sealing gasket.

[0106] In this embodiment, a sealing element 41 is provided between the battery device 104 and the front crossbeam 10, the left side beam 311 and the right side beam 321. This not only seals the vehicle body 103 and the battery device 104, but also acts as a buffer when the left side beam 311 and the right side beam 321 are pressed against the upper cover plate 71 of the battery device 104.
