[0057] Before the protective structure and the vehicle provided by the present application are described in detail, the application scenario of the protective structure and the vehicle is described first:

[0058] As shown in FIG. 1, FIG. 1 shows an impact force conduction schematic diagram of a fuel vehicle in the related art. In order to resist the impact from the front during collision, the fuel vehicle usually arranges a floor under longitudinal beam 2 and a front longitudinal beam 1 under the floor of the vehicle to overlap, ensuring the continuity of impact force conduction and dispersion, avoiding the emergence of section mutation characteristics. When the front compartment 3 of the vehicle is subjected to a frontal impact, most of the impact force can be conducted to the rear of the vehicle body through the floor under longitudinal beam 2 and the front longitudinal beam 1, reducing the intrusion of the front wall, thereby achieving the effect of protecting the passenger compartment.

[0059] In a new energy vehicle (including a hybrid vehicle or an electric vehicle), a power battery is usually installed under a floor, and it is not easy to arrange a floor force transmission beam, so that the impact force of the front beam 1 cannot be transmitted to the rear along the floor beam 2, which is easy to cause insufficient resistance of the front wall panel and increase the intrusion amount. In addition, due to the height difference between the front beam 1 and the power battery pack and the lack of structure transition, the vehicle front compartment 3 is often prone to instability and forward overturning during the frontal impact, which affects the safety of the vehicle.

[0060] To this end, the present application provides a vehicle which at least partially solves the above technical problems. The vehicle provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments and application scenarios thereof.

[0061] As shown in FIGS. 2-6, the vehicle according to some embodiments of the present application includes a vehicle body 20 and a protection structure 10; the vehicle body 20 is provided with a first mounting portion 201 for mounting a subframe 40 and a second mounting portion 202 for mounting a battery pack 30; at least part of the protection structure 10 is arranged between the first mounting portion 201 and the second mounting portion 202, and the protection structure 10 extends along a first direction Y, which is the width direction of the vehicle.

[0062] In the embodiments of the present application, the vehicle body 20 is provided with the first mounting portion 201 for mounting the subframe 40 and the second mounting portion 202 for mounting the battery pack 30, and there is a certain gap between the first mounting portion 201 and the second mounting portion 202. By arranging the protection structure 10 at the gap and extending the protection structure 10 along the width direction of the vehicle, when the vehicle is subjected to frontal impact, the impact force can be conducted to the protection structure 10 via the subframe 40, and then conducted rearward by the protection structure 10, so that most of the impact force can be conducted to the rear of the vehicle body 20, reducing the force of the front compartment components intruding into the passenger compartment, thereby achieving the effect of protecting the passenger compartment and improving the safety performance of the vehicle.

[0063] It can be understood that the vehicle structure in the present application can be applied to new energy vehicles, such as electric vehicles, plug-in hybrid vehicles, or extended-range electric vehicles. Of course, it can also be applied to other types of vehicles, which are not limited herein.

[0064] In some embodiments, as shown in FIGS. 2-5, the vehicle can include a vehicle body 20, a subframe 40 arranged below a front compartment of the vehicle body, and a battery pack 30 arranged below a floor 22 of the vehicle body 20, the vehicle body 20 being provided with a first mounting portion 201 and a second mounting portion 202 arranged at intervals along a length direction (i.e., a second direction X) of the vehicle, the subframe 40 being mounted to the first mounting portion 201, and the battery pack 30 being mounted to the second mounting portion 202. There is a spacing region 10a between the first mounting portion 201 and the second mounting portion 202, the protective structure 10 is arranged at the spacing region 10a, and at least part of the protective structure 10 is located between the first mounting portion 201 and the second mounting portion 202, and the protective structure 10 can be fixedly connected with the vehicle body 20.

[0065] In some embodiments, as shown in FIGS. 2-5, the vehicle can include a vehicle body 20, a subframe 40 arranged below a front compartment of the vehicle body, and a battery pack 30 arranged below a floor 22 of the vehicle body 20, the vehicle body 20 being provided with a first mounting portion 201 and a second mounting portion 202 arranged at intervals along a length direction (i.e., a second direction X) of the vehicle, the subframe 40 being mounted to the first mounting portion 201, and the battery pack 30 being mounted to the second mounting portion 202. There is a spacing region 10a between the first mounting portion 201 and the second mounting portion 202, the protective structure 10 is arranged at the spacing region 10a, and at least part of the protective structure 10 is located between the first mounting portion 201 and the second mounting portion 202, and the protective structure 10 can be fixedly connected with the vehicle body 20.

[0066] In some embodiments, as shown in FIGS. 3 and 7, the length direction of the vehicle is the second direction X, and a first gap A is arranged between the protective structure 10 and the first mounting portion 201 along the second direction X.

[0067] In the embodiments of the present application, the first gap A is arranged between the protective structure 10 and the first mounting portion 201, so as to reserve a certain retreat failure space for the subframe 40 when the subframe 40 is mounted to the first mounting portion 201, and the first gap A can also avoid the generation of abnormal noise or local damage due to the rigid friction between the protective structure 10 and the subframe 40 during the driving of the vehicle.

[0068] In some embodiments, as shown in FIGS. 3 and 7, the size of the first gap A along the second direction X is less than or equal to 80 mm.

[0069] It can be understood that if the gap between the subframe 40 and the protective structure 10 is too large, the collision force received by the subframe 40 cannot be timely conducted to the rear of the vehicle body 20 via the protective structure 10, so that a large deformation of the front compartment of the vehicle is generated, which cannot protect the passenger compartment. Therefore, by arranging the size of the first gap A along the second direction X to be less than or equal to 80 mm, the collision force received by the subframe 40 can be timely conducted to the protective structure 10, and then conducted to the rear of the vehicle body 20 by the protective structure 10, so as to reduce the intrusion of the front panel 23 and achieve the protection of the passenger compartment.

[0070] It should be noted that the size of the first gap A refers to the distance between the side of the protection structure 10 close to the first mounting portion 201 and the side of the first mounting portion 201 close to the protection structure 10. When the auxiliary frame 40 is connected to the first mounting portion 201, the distance between the side of the auxiliary frame 40 close to the protection structure 10 and the side of the protection structure 10 close to the auxiliary frame 40 can be measured as the size of the first gap A.

[0071] In some embodiments, the size of the first gap A along the second direction X is H1, which satisfies: 25mm≤H1≤80mm. For example, the size H1 of the first gap A along the second direction X can be set to be: 25mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, etc.

[0072] In the embodiments of the present application, by setting the reasonable size of the first gap A, it can be ensured that the collision force received by the auxiliary frame 40 can be timely conducted to the rear of the vehicle body 20 via the protection structure 10, and at the same time, it can be ensured that there is a certain buffer space between the protection structure 10 and the auxiliary frame 40, and a certain retreat failure space is reserved for the auxiliary frame 40.

[0073] In some embodiments, as shown in FIGS. 3 and 4, the vehicle further includes a battery pack 30, the vehicle body 20 includes a battery pack mounting beam 21, the battery pack mounting beam 21 is arranged below the floor 22 of the vehicle body 20, the second mounting portion 202 is formed by the battery pack mounting beam 21, the battery pack 30 is mounted to the battery pack mounting beam 21, and the protection structure 10 is connected and fixed with the battery pack mounting beam 21.

[0074] The battery pack 30 can include a battery pack body 31 and a battery pack connecting portion 32 connected with each other, and the battery pack connecting portion 32 is connected to the battery pack mounting beam 21 to achieve mounting and fixing of the battery pack 30.

[0075] In some embodiments, in the case that the battery pack 30 and the protection structure 10 are both connected to the battery pack mounting beam 21, the normal projection of the battery pack connecting portion 32 along the width direction (i.e., the first direction Y) of the vehicle at least partially overlaps with the protection structure 10.

[0076] In some other embodiments, the vehicle further includes a battery pack 30, the vehicle body 20 includes a floor 22, the second mounting portion 202 is arranged below the floor 22, the battery pack 30 is connected and fixed with the second mounting portion 202 of the floor 22, and one end of the protection structure 10 close to the battery pack 30 is connected and fixed with the floor 22.

[0077] The battery pack 30 can include a battery pack body 31 and a battery pack connecting portion 32 connected to each other, and the battery pack connecting portion 32 is connected to the second mounting portion 202 provided in the floor 22 to realize mounting and fixing of the battery pack 30.

[0078] In some embodiments, the vehicle further includes a battery pack 30, the vehicle body 20 includes a floor 22, the protection structure 10 is connected to the floor 22, and the end of the protection structure 10 is provided with a second mounting portion 202, and the battery pack 30 is connected to the second mounting portion 202 of the protection structure 10.

[0079] The battery pack 30 can include a battery pack body 31 and a battery pack connecting portion 32 connected to each other, and the battery pack connecting portion 32 is connected to the second mounting portion 202 provided at the end of the protection structure 10 to realize mounting and fixing of the battery pack 30.

[0080] In some embodiments, as shown in FIGS. 3 and 7, the length direction of the vehicle is a second direction X, and a second gap B exists between the protection structure 10 and the battery pack body 31 along the second direction X.

[0081] In the embodiments of the present application, by providing the second gap B between the protection structure 10 and the battery pack body 31, a certain retreat deformation space is reserved for the protection structure 10 to play a buffering role, and at the same time, the rigid friction between the protection structure 10 and the battery pack 30 during vehicle driving is avoided to generate abnormal sound and cause damage to the battery pack 30.

[0082] In some embodiments, as shown in FIGS. 3 and 7, the size of the second gap B along the second direction X is less than or equal to 40 mm.

[0083] It can be understood that if the gap between the battery pack body 31 and the protection structure 10 is too large, after the impact force of the subframe 40 is conducted to the protection structure 10, it cannot be conducted backward in time, so that a large deformation of the front compartment of the vehicle is caused, which cannot play a protection role for the passenger compartment. Therefore, by setting the size of the second gap B along the second direction X to be less than or equal to 40 mm, when the subframe 40 is subjected to the impact force, the impact force can be conducted to the rear of the vehicle body 20 in time through the protection structure 10 and the battery pack 30, the intrusion of the front cross member 23 is reduced, and the protection role for the passenger compartment is achieved.

[0084] It should be noted that the size of the second gap B refers to the distance between the side of the protection structure 10 and the side of the battery pack body 31 close to each other.

[0085] In some embodiments, the size of the second gap B along the second direction X is H2, and 20 mm≤H2≤40 mm is satisfied. Exemplarily, the size H2 of the second gap B along the second direction X can be set to 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, etc.

[0086] In the embodiment of the present application, by setting a reasonable size of the second gap B, the impact force of the sub-frame 40 can be timely transmitted backward after being transmitted to the protection structure 10, and at the same time, a certain buffer space can be ensured between the protection structure 10 and the battery pack 30.

[0087] In some embodiments, as shown in FIG. 4, the vehicle body 20 includes a front panel 23 and a front panel beam 231, the front panel 23 is connected with the front panel beam 231, and an end of the protection structure 10 towards the first mounting portion 201 is connected with the front panel beam 231.

[0088] In the embodiment of the present application, the vehicle body 20 is provided with the front panel 23 and the front panel beam 231, the front panel 23 is connected with the front panel beam 231, and a certain cavity can be enclosed between the front panel 23 and the front panel beam 231 for arrangement of the vehicle front compartment structure, and then the protection structure 10 is connected with the front panel beam 231 to realize mounting and fixing of the protection structure 10 and the vehicle body 20.

[0089] In some embodiments, as shown in FIG. 3, the vehicle further includes a sub-frame 40, the sub-frame 40 is connected to the first mounting portion 201, and a gap is present between the sub-frame 40 and at least part of the protection structure 10.

[0096] In the embodiment of the present application, the distance between the at least one preset hole 110a and the first mounting hole 401 is set to be between 50mm and 100mm, so as to ensure the connection strength of the protection structure 10 and the vehicle body 20, and ensure the protection structure 10 to have a certain variability in the part corresponding to the first mounting hole 401, so as to be able to absorb the impact force conducted by the auxiliary frame 40 and play a buffering role.

[0097] It can be understood that the vehicle body 20 includes a front wall 23 and a front wall beam 231, the front wall 23 is connected with the front wall beam 231, the protection structure 10 is connected with the front wall beam 231 through the second mounting hole 110, and when subjected to external force impact, the protection structure 10 in the part corresponding to the second mounting hole 110 is not easy to deform due to the connection state, while the part outside the second mounting hole 110 is in a free state and is easy to deform.

[0098] To this end, in the present application, at least one second mounting hole 110 (i.e. a preset hole 110a) is arranged close to the first mounting hole 401, and the distance between the preset hole 110a and the first mounting hole 401 is set within a certain range, so that when the subframe 40 is impacted, the impact force is conducted to the protection structure 10 through the part of the subframe 40 where the first mounting hole 401 is located, and the corresponding part of the protection structure 10 deforms to absorb energy.

[0099] If the second mounting hole 110 is too close to the first mounting hole 401, it is not only inconvenient for the design and installation of the second mounting hole 110 and the first mounting hole 401, but also the corresponding part of the protection structure 10 and the first mounting hole 401 cannot easily deform, which cannot effectively absorb energy. If the second mounting hole 110 is too far away from the first mounting hole 401, when the impact force of the subframe 40 is conducted to the protection structure 10, the deformation of the corresponding part of the protection structure 10 is too large, which cannot effectively support the subframe 40.

[0100] In some embodiments, as shown in FIGS. 3 and 7, the protection structure 10 includes a first connecting portion 11, a second connecting portion 12, and a reinforcing portion 13; the first connecting portion 11 is arranged on the side of the reinforcing portion 13 facing the first mounting portion 201, and is used to connect with the front apron beam 231 of the vehicle body 20; the second connecting portion 12 is arranged on the side of the reinforcing portion 13 away from the first connecting portion 11, and is used to connect with the battery pack mounting beam 21, or the floor 22, or the battery pack 30.

[0101] In the embodiments of the present application, the first connecting portion 11 and the second connecting portion 12 are arranged at both ends of the protection structure 10, so as to be connected with the vehicle body 20 through the first connecting portion 11 and the second connecting portion 12, to realize the installation and fixation of the protection structure 10; the reinforcing portion 13 is arranged between the first connecting portion 11 and the second connecting portion 12, to improve the overall structural strength of the protection structure 10, so that the protection structure 10 can conduct the impact force received by the subframe 40, to support the subframe 40.

[0102] In some embodiments, the vehicle body 20 can include a front apron 23 and a front apron beam 231, the front apron 23 and the front apron beam 231 are connected, and the first connecting portion 11 of the protection structure 10 can be connected with the front apron beam 231, to realize the installation and fixation of one end of the protection structure 10.

[0103] Further, the vehicle body 20 further comprises a floor 22. When a battery pack mounting beam 21 is arranged below the floor 22, the second connecting portion 12 of the protection structure 10 can be connected to the battery pack mounting beam 21. When no battery pack mounting beam 21 is arranged below the floor 22, the second connecting portion 12 can be directly connected and fixed with the floor 22. At this time, the battery pack 30 can be mounted on the floor 22, or the battery pack 30 can be connected and fixed with the second connecting portion 12 of the protection structure 10. The specific connection structure can be flexibly set according to the actual situation, which is not limited herein.

[0104] In some embodiments, as shown in FIG. 3, the reinforcing portion 13 is provided with a hollow structure 101. By arranging the hollow structure 101 in the reinforcing portion 13 of the protection structure 10, when the protection structure 10 is subjected to an impact force, the hollow structure 101 can deform to absorb energy, thereby playing a supporting role for the subframe 40 and a protection role for the battery pack 30.

[0105] In some embodiments, as shown in FIG. 3, the first connecting portion 11 and the second connecting portion 12 are both hollow structures, and the cross section of the first connecting portion 11 and the second connecting portion 12 can be a "U" shaped cross section. The wall thickness of the first connecting portion 11 and the second connecting portion 12 is greater than or equal to the wall thickness of the shell of the reinforcing portion 13, so as to increase the strength of the first connecting portion 11 and the second connecting portion 12.

[0106] For example, the wall thickness of the first connecting portion 11 and the second connecting portion 12 can be 2.5mm-3mm, and the wall thickness of the shell of the reinforcing portion 13 can be 2mm-2.5mm. Of course, the specific structure size can be flexibly adjusted according to the actual design needs, which is not limited herein.

[0107] In other embodiments, the first connecting portion 11 and the second connecting portion 12 can also be provided as solid structures, so as to increase the structural strength of the first connecting portion 11 and the second connecting portion 12. The size and shape structure of the first connecting portion 11 and the second connecting portion 12 can be determined according to the structure design needs of the vehicle, which is not limited herein.

[0108] In some embodiments, as shown in FIG. 4 and FIG. 8, the protection structure 10 further comprises a reinforcing rib 132, and the reinforcing portion 13 is provided with a cavity, and the reinforcing rib 132 is arranged in the cavity to form the hollow structure 101.

[0109] In the embodiments of the present application, the cavity is arranged in the reinforcing portion 13, so that the reinforcing portion 13 has a certain variability space, thereby being able to play an energy absorption role to reduce the collision force conducted to the battery pack 30. At the same time, the reinforcing rib 132 is arranged in the cavity of the reinforcing portion 13 to reinforce the reinforcing portion 13 and improve the overall structural strength of the reinforcing portion 13.

[0110] In some embodiments, as shown in FIGS. 8 and 9, the reinforcing rib 132 includes a first reinforcing rib 1321 connected to the first position 131a of the reinforcing portion 13, which is adapted to correspond to the bending transition of the front wall 23, and the other end of the first reinforcing rib 1321 extends in the third direction Z, i.e., the height direction of the vehicle, away from the front wall 23.

[0111] In the embodiments of the present application, the first reinforcing rib 1321 is arranged in the cavity of the reinforcing portion 13 and connected to the first position 131a of the reinforcing portion 13, so as to reinforce the first position 131a of the reinforcing portion 13. When the protection structure 10 is installed on the vehicle, the first position 131a of the reinforcing portion 13 corresponds to the bending transition of the front wall 23, so as to reinforce the bending transition of the front wall 23.

[0112] It can be understood that the vehicle body 20 includes the front wall 23, a portion of which extends to the rear of the vehicle and is connected to the floor 22, and a portion of which extends upwardly and obliquely to the front of the vehicle, so as to separate the front compartment of the vehicle from the passenger compartment, thereby forming a bending transition between the front and rear portions of the front wall 23. When the vehicle is subjected to a collision impact, the collision force is transmitted to the front wall 23, and the front wall 23 is prone to deformation and damage due to stress concentration at the bending transition.

[0113] Correspondingly, the reinforcing portion 13 at the position corresponding to the bending transition of the front wall 23 is also a stress concentration position. Therefore, in the present application, the first reinforcing rib 1321 is arranged in the cavity of the reinforcing portion 13 and connected to the first position 131a of the reinforcing portion 13, so as to reinforce the first position 131a of the reinforcing portion 13 and improve the support and protection of the protection structure 10 on the bending transition of the front wall 23.

[0114] In some embodiments, one end of the first reinforcing rib 1321 is connected to the first position 131a of the reinforcing portion 13, and the other end extends in the third direction Z, i.e., the height direction of the vehicle, away from the front wall 23. It should be noted that the extension direction of the first reinforcing rib 1321 can be parallel to the third direction Z, or can form an acute angle with the third direction Z. The angle between the first reinforcing rib 1321 and the third direction Z can be flexibly set according to actual conditions, and is not limited herein.

[0115] In some embodiments, as shown in FIGS. 8 and 9, the reinforcing rib 132 further comprises a second reinforcing rib 1322, one end of the second reinforcing rib 1322 is connected to the first position 131a of the reinforcing portion 13, the other end of the second reinforcing rib 1322 extends in the third direction Z towards a direction away from the first position 131a, and the extending directions of the first reinforcing rib 1321 and the second reinforcing rib 1322 intersect.

[0116] In the embodiments of the present application, by simultaneously arranging the first reinforcing rib 1321 and the second reinforcing rib 1322 in the cavity of the reinforcing portion 13, and connecting the first reinforcing rib 1321 and the second reinforcing rib 1322 to the first position 131a of the reinforcing portion 13, the first position 131a of the reinforcing portion 13 is reinforced. At the same time, the first reinforcing rib 1321 and the second reinforcing rib 1322 extend in different directions, so that a triangular support structure can be formed by the first reinforcing rib 1321 and the second reinforcing rib 1322 to support and reinforce the first position 131a of the shell, thereby improving the reinforcing effect.

[0117] In some embodiments, as shown in FIG. 8, one end of the first reinforcing rib 1321 is connected to the first position 131a of the reinforcing portion 13, and the other end extends towards a direction away from the front wall 23 and close to the auxiliary frame 40; one end of the second reinforcing rib 1322 is connected to the first position 131a of the reinforcing portion 13, and the other end extends towards a direction away from the front wall 23 and close to the battery pack 30.

[0118] In some embodiments, as shown in FIG. 8, the reinforcing rib 132 further comprises a third reinforcing rib 1323, and the third reinforcing rib 1323 is cross-connected with the first reinforcing rib 1321. The cross-connection refers to that the extending directions of the third reinforcing rib 1323 and the first reinforcing rib 1321 intersect.

[0119] In the embodiments of the present application, by arranging the third reinforcing rib 1323 in the cavity of the reinforcing portion 13, the third reinforcing rib 1323 is cross-connected with the first reinforcing rib 1321, that is, the first reinforcing rib 1321 and the third reinforcing rib 1323 form a cross support structure, thereby improving the reinforcing effect of the reinforcing portion 13.

[0120] In some embodiments, as shown in FIG. 8, the reinforcing rib 132 further comprises a fourth reinforcing rib 1324, and the fourth reinforcing rib 1324 is cross-connected with the second reinforcing rib 1322. The cross-connection refers to that the extending directions of the fourth reinforcing rib 1324 and the second reinforcing rib 1322 intersect.

[0121] In the embodiment of the present application, the fourth reinforcing rib 1324 is arranged in the cavity of the reinforcing portion 13, and the fourth reinforcing rib 1324 is cross-connected with the second reinforcing rib 1322, that is, the fourth reinforcing rib 1324 and the second reinforcing rib 1322 form a cross support structure, so as to improve the reinforcing effect of the reinforcing portion 13.

[0122] In some embodiments, the third reinforcing rib 1323 and the fourth reinforcing rib 1324 can each be provided with one or more, and the specific number can be flexibly set according to actual needs.

[0123] It should be noted that, in addition to the first reinforcing rib 1321, the second reinforcing rib 1322, the third reinforcing rib 1323 and the fourth reinforcing rib 1324 arranged in the cavity of the reinforcing portion 13, other structure reinforcing ribs 132 can also be arranged to improve the reinforcing effect of the reinforcing portion 13, and the specific structure arrangement can be flexibly set according to actual needs, which is not limited herein.

[0124] In addition, the thickness of the shell of the reinforcing portion 13 is greater than or equal to the thickness of the reinforcing rib 132, so as to improve the strength of the shell of the reinforcing portion 13, and the specific thickness can be flexibly set according to actual needs, which is not limited herein.

[0125] In some embodiments, as shown in FIG. 6, the first connecting portion 11 is provided with a plurality of second mounting holes 110 arranged at intervals along the first direction Y, and the second mounting hole 110 is used to connect with the front wall beam 231.

[0126] In the embodiment of the present application, a plurality of second mounting holes 110 are arranged at intervals in the first connecting portion 11, so that during installation, the fastener can pass through the second mounting hole 110 to connect with the front wall beam 231 of the vehicle body 20, thereby realizing the installation and fixation of the protection structure 10.

[0127] In some embodiments, a plurality of second mounting holes 110 can be arranged at equal intervals. In this way, the connection points of the first connecting portion 11 and the front wall beam 231 can be more evenly distributed, so as to ensure the connection strength of the protection structure 10 at different positions and the front wall beam 231.

[0128] In some embodiments, as shown in FIG. 6, the distance between the adjacent two second mounting holes 110 is M1, and satisfies: 400mm≤M1≤500mm. For example, the distance M1 between the adjacent two second mounting holes 110 can be set as: 400mm, 420mm, 450mm, 480mm, 500mm, etc.

[0129] In the present application, by setting a reasonable range of the spacing M1 between the two adjacent second mounting holes 110, the spacing of the second mounting holes 110 is avoided to be too small, so that the number of the second mounting holes 110 needed to be arranged in the first connecting part 11 is too much, which not only occupies more installation space, but also increases the difficulty of installation and disassembly. If the spacing of the second mounting holes 110 is too large, the number of the second mounting holes 110 arranged in the first connecting part 11 is too small, so that the connection strength of the first connecting part 11 and the front wall 23 is insufficient, and when the vehicle is subjected to a collision, the protection structure 10 is prone to fall off or large deformation, and cannot effectively support the auxiliary frame 40 and effectively protect the battery pack 30.

[0130] In some embodiments, as shown in FIG. 6, the second connecting part 12 is provided with a plurality of third mounting holes 120 arranged at intervals along the first direction Y, and the third mounting holes 120 are used to connect with the battery pack mounting beam 21 or the floor 22.

[0131] In the embodiments of the present application, by arranging a plurality of third mounting holes 120 at intervals in the second connecting part 12, the third mounting holes 120 can be passed through by fasteners to connect with the battery pack mounting beam 21 or the floor 22 during installation, so as to realize the connection and fixation of the protection structure 10 and the battery pack mounting beam 21 or the floor 22.

[0132] In some embodiments, the third mounting holes 120 can be arranged at equal intervals. In this way, the connection points of the second connecting part 12 and the battery pack mounting beam 21 or the floor 22 can be more evenly distributed, so as to ensure the connection strength of the protection structure 10 at different positions and the battery pack mounting beam 21 or the floor 22.

[0133] In some embodiments, as shown in FIG. 6, the spacing between the two adjacent third mounting holes 120 is M2, which satisfies: 400mm≤M2≤500mm. For example, the spacing M2 between the two adjacent third mounting holes 120 can be set as: 400mm, 420mm, 450mm, 480mm, 500mm, etc.

[0134] In the embodiments of the present application, by setting a reasonable range of the spacing M2 between the two adjacent third mounting holes 120, the spacing of the third mounting holes 120 is avoided to be too small, so that the number of the third mounting holes 120 arranged in the second connecting part 12 is too much, which not only occupies more installation space, but also increases the difficulty of installation and disassembly, and is not convenient for actual use and operation. If the spacing of the third mounting holes 120 is too large, the number of the third mounting holes 120 arranged in the second connecting part 202 is too small, which results in insufficient connection strength of the first connecting part 11 and the front wall 23, and when the vehicle is subjected to a collision, the protection structure 10 is prone to fall off or large deformation, and cannot effectively support the auxiliary frame 40 and effectively protect the battery pack 30.

[0135] It should be noted that the distance between two adjacent second mounting holes 110 and the distance between two adjacent third mounting holes 120 can be set to be equal or unequal. It can be flexibly set according to actual needs and is not limited here.

[0136] In some embodiments, the length of the protective structure 10 along the first direction Y is L mm; the number S1 of the second mounting holes 110 provided in the first connecting portion 11 satisfies: S1≥L / 400, or S1≥4.

[0137] In this embodiment, the number S1 of second mounting holes 110 provided in the first connecting portion 11 is determined based on the length L of the protective structure 10 along the first direction Y, or the number S1 of second mounting holes 110 is greater than or equal to 4. This ensures that the first connecting portion 11 has a reasonable number of second mounting holes 110 to guarantee the connection strength between the first connecting portion 11 and the front bulkhead beam 231.

[0138] In some embodiments, the length of the protective structure 10 along the first direction Y is L mm; the number S2 of the third mounting holes 120 provided in the second connecting portion 12 satisfies: S2≥L / 400, or S2≥4.

[0139] In this embodiment, the number S2 of the third mounting holes 120 provided in the second connecting portion 12 is determined based on the length L of the protective structure 10 along the first direction Y, or the number S2 of the third mounting holes 120 is greater than or equal to 4. This ensures that the second connecting portion 12 has a reasonable number of third mounting holes 120 to guarantee the connection strength between the second connecting portion 12 and the crossbeam or floor 22 of the battery pack 30.

[0140] In some embodiments, as shown in FIG3, the height of the first connecting portion 11 along the third direction Z is greater than or equal to 15mm, where the third direction Z is the height direction of the vehicle. For example, the height of the first connecting portion 11 along the third direction Z can be set to 15mm, 16mm, 17mm, 18mm, 20mm, 30mm, etc.

[0141] In this embodiment, by setting the height of the first connecting part 11 along the third direction Z to be greater than or equal to 15mm, the first connecting part 11 is ensured to have a certain height, so that when the subframe 40 is hit, the impact force can be transmitted from the subframe 40 to the protective structure 10 through the first connecting part 11, thereby ensuring that the protective structure 10 can support the subframe 40.

[0142] In some embodiments, as shown in FIGS. 4 and 8, the first connecting portion 11 and the reinforcing portion 13 are integrally formed. By setting the first connecting portion 11 and the reinforcing portion 13 as integrally formed, the structural strength of the first connecting portion 11 and the reinforcing portion 13 is improved, and actual processing is facilitated.

[0143] In some other embodiments, as shown in FIGS. 4 and 8, the second connecting portion 12 and the reinforcing portion 13 are integrally formed. By setting the second connecting portion 12 and the reinforcing portion 13 as integrally formed, the structural strength of the second connecting portion 12 and the reinforcing portion 13 is improved, and actual processing is facilitated.

[0144] In some other embodiments, as shown in FIGS. 4 and 8, the first connecting portion 11, the second connecting portion 12, and the reinforcing portion 13 are integrally formed. By setting the first connecting portion 11, the second connecting portion 12, and the reinforcing portion 13 as integrally formed, the structural strength of the entire protective structure 10 is improved, and the processing and manufacturing of the protective structure 10 are facilitated.

[0145] In some other embodiments, the protective structure 10 can be made of an aluminum extrusion, which can ensure a certain structural strength of the protective structure 10, reduce the weight of the protective structure 10, and reduce the use cost.

[0146] Of course, the protective structure 10 can also be made of other materials such as aluminum alloy and composite material, and the skilled in the art can select them flexibly according to actual needs, which are not limited herein.

[0147] In some embodiments, as shown in FIGS. 4 and 8, the height direction of the vehicle is the third direction Z, and along the third direction Z, the surface of the first connecting portion 11 away from the vehicle body 20 is higher than the surface of the second connecting portion 12 away from the vehicle body 20.

[0148] In some embodiments, along the height direction of the vehicle, the surface of the first connecting portion 11 away from the vehicle body 20 is higher than the surface of the second connecting portion 12 away from the vehicle body 20, that is, the lower surface of the first connecting portion 11 is higher than the lower surface of the second connecting portion 12, so as to form a height difference between the lower surface of the first connecting portion 11 and the lower surface of the second connecting portion 12. After the collision force of the auxiliary frame 40 is transmitted to the protective structure 10, the protective structure 10 can maintain a good crushing deformation mode, thereby effectively supporting and protecting.

[0149] In some embodiments, as shown in FIGS. 4 and 8, the size of the reinforcing portion 13 along the third direction Z gradually increases from the first connecting portion 11 to the second connecting portion 12, and the third direction Z is the height direction of the vehicle.

[0150] In the embodiment of the present application, the dimension of the reinforcing portion 13 in the third direction Z gradually increases from the first connecting portion 11 to the second connecting portion 12, so that when the protection structure 10 is subjected to the impact force, the deformation is first generated from the side of the reinforcing portion 13 close to the first connecting portion 11, and then the impact force is gradually transmitted to the side close to the second connecting portion 12, so that the protection structure 10 maintains a good crushing deformation mode, and can effectively support and protect. In addition, the gradually increasing dimension of the reinforcing portion 13 can also avoid the stress concentration phenomenon caused by the sudden change of the local cross section of the reinforcing portion 13.

[0151] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily mean the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0152] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
