For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0057] Before describing in detail the protective structure and vehicle provided by this application, the application scenarios of the protective structure and vehicle are described first:

[0058] like Figure 1 As shown, Figure 1 The schematic diagram of impact force transmission during a collision of a fuel vehicle in the prior art is shown. In order to resist the impact from the front during a collision, a fuel vehicle usually arranges a floor lower longitudinal beam 2 under the floor of the vehicle to overlap with the front longitudinal beam 1 to ensure the continuity of impact force transmission and dispersion and avoid the occurrence of cross-sectional mutation characteristics. When the front cabin 3 of the vehicle is hit head-on, most of the impact force can be transmitted to the rear of the vehicle body through the floor lower longitudinal beam 2 and the front longitudinal beam 1, reducing the intrusion of the front panel, thereby protecting the passenger compartment.

[0059] In new energy vehicles (including hybrid vehicles or pure electric vehicles), power batteries are usually installed under the floor, and it is not easy to arrange the floor force transmission longitudinal beam, so that the collision force of the rear of the front longitudinal beam 1 cannot be further transmitted backward along the longitudinal beam 2 under the floor, which easily causes insufficient resistance of the front panel and increased intrusion. In addition, due to the height difference between the front longitudinal beam 1 and the power battery pack and the lack of structural transition, the front cabin 3 of the vehicle is often prone to instability and tipping forward during a frontal collision, affecting the safety of the vehicle.

[0060] To this end, the present application provides a vehicle that at least partially solves the above technical problems. The vehicle provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0061] like Figures 2 to 6 As shown, a vehicle according to some embodiments of the present application includes a vehicle body 20 and a protective 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 protective structure 10 is provided between the first mounting portion 201 and the second mounting portion 202, and the protective structure 10 extends along a first direction Y, which is the width direction of the vehicle.

[0062] In the embodiment of the present application, the vehicle body 20 is provided with a first mounting portion 201 and a second mounting portion 202. The first mounting portion 201 is used to mount the subframe 40, and the second mounting portion 202 is used to mount the battery pack 30. There is a certain gap between the first mounting portion 201 and the second mounting portion 202. By arranging the protective structure 10 at the gap and extending the protective structure 10 along the width direction of the vehicle, when the vehicle is subjected to a frontal collision, the impact force can be transmitted to the protective structure 10 via the subframe 40, and then transmitted backward by the protective structure 10. In this way, most of the impact force can be transmitted to the rear of the vehicle body 20, reducing the force of the front cabin components invading the member cabin, thereby protecting the passenger cabin and improving the safety performance of the vehicle.

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

[0064] Specifically, Figures 2 to 5 As shown, the vehicle may include a vehicle body 20, a subframe 40 and a battery pack 30. The subframe 40 is arranged below the front compartment of the vehicle body, and the battery pack 30 is arranged below the floor 22 of the vehicle body 20. The vehicle body 20 is provided with a first mounting portion 201 and a second mounting portion 202. The first mounting portion 201 and the second mounting portion 202 are arranged at intervals along the length direction of the vehicle (i.e., the second direction X). The subframe 40 is installed on the first mounting portion 201, and the battery pack 30 is installed on the second mounting portion 202. There is a spacing area 10a between the first mounting portion 201 and the second mounting portion 202. The protective structure 10 is arranged at the spacing area 10a, and at least part of the protective structure 10 is located between the first mounting portion 201 and the second mounting portion 202. The protective structure 10 can be connected and fixed to the vehicle body 20.

[0065] The subframe here refers to the front subframe of the vehicle. Along the width direction of the vehicle (i.e., the first direction Y), the protective structure 10 can extend to the inner side of the door sills on both sides of the vehicle, thereby playing a role in strengthening the protection of different positions between the subframe 40 and the battery pack 30. Of course, the size structure of the protective structure 10 along the first direction Y can be determined according to the actual structural design requirements of the vehicle, and is not limited here.

[0066] Alternatively, if Figure 3 and Figure 7 As shown, the length direction of the vehicle is the second direction X. Along the second direction X, a first gap A is provided between the protective structure 10 and the first mounting portion 201 .

[0067] In the embodiment of the present application, a first gap A is provided between the protective structure 10 and the first mounting portion 201 so that when the sub-frame 40 is installed on the first mounting portion 201, a certain amount of space for retreat failure is reserved for the sub-frame 40. At the same time, by providing the first gap A, it is also possible to avoid abnormal noise or local damage caused by rigid friction between the protective structure 10 and the sub-frame 40 during driving of the vehicle.

[0068] Alternatively, if Figure 3 and Figure 7 As shown, the dimension of the first gap A along the second direction X is less than or equal to 80 mm.

[0069] It is understandable 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 transmitted to the rear of the vehicle body 20 via the protective structure 10 in time, so that the front cabin of the vehicle will be greatly deformed and cannot protect the passenger cabin. Therefore, by setting the first gap A to be less than or equal to 80 mm in the second direction X, the collision force received by the subframe 40 can be transmitted to the protective structure 10 in time, and then transmitted to the rear of the vehicle body 20 by the protective structure 10, thereby reducing the intrusion of the front panel 23, thereby protecting the passenger cabin.

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

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

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

[0073] In some embodiments, Figure 3 and Figure 4 As shown, the vehicle also includes a battery pack 30, and the vehicle body 20 includes a battery pack mounting beam 21, which is arranged below the floor 22 of the vehicle body 20, and is formed as the second mounting portion 202 by the battery pack mounting beam 21, and the battery pack 30 is mounted on the battery pack mounting beam 21, and at the same time, the protective structure 10 is connected and fixed to the battery pack mounting beam 21.

[0074] The battery pack 30 may include a battery pack body 31 and a battery pack connection portion 32 that are connected to each other. The battery pack connection portion 32 is connected to the battery pack mounting beam 21 to achieve installation and fixation of the battery pack 30 .

[0075] Specifically, when the battery pack 30 and the protective structure 10 are simultaneously connected to the battery pack mounting beam 21 , along the width direction of the vehicle (ie, the first direction Y), the battery pack connecting portion 32 at least partially overlaps with the orthographic projection of the protective structure 10 .

[0076] In other embodiments, the vehicle also includes a battery pack 30, the body 20 includes a floor 22, the second mounting portion 202 is provided under the floor 22, the battery pack 30 is connected and fixed to the second mounting portion 202 of the floor 22, and the protective structure 10 is connected and fixed to the floor 22 at one end facing the battery pack 30.

[0077] The battery pack 30 may include a battery pack body 31 and a battery pack connection portion 32 that are connected to each other. The battery pack connection portion 32 is connected to a second mounting portion 202 provided in the floor 22 to achieve installation and fixation of the battery pack 30 .

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

[0079] The battery pack 30 may include a battery pack body 31 and a battery pack connection portion 32 that are connected to each other. The battery pack connection portion 32 is connected to a second mounting portion 202 disposed at the end of the protective structure 10 to achieve installation and fixation of the battery pack 30 .

[0080] Alternatively, if Figure 3 and Figure 7 As shown, the longitudinal direction of the vehicle is the second direction X, and a second gap B exists between the protective structure 10 and the battery pack body 31 along the second direction X.

[0081] In the embodiment of the present application, a second gap B is set between the protective structure 10 and the battery pack body 31 to reserve a certain amount of space for backward deformation for the protective structure 10 to play a buffering role, while avoiding rigid friction between the protective structure 10 and the battery pack 30 during vehicle driving to generate abnormal noise and damage to the battery pack 30.

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

[0083] It is understandable that if the gap between the battery pack body 31 and the protective structure 10 is too large, the impact force of the subframe 40 cannot be transmitted backward in time after being transmitted to the protective structure 10, so that the front cabin of the vehicle will be greatly deformed and cannot protect 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 40mm, the impact force of the subframe 40 can be transmitted to the rear of the vehicle body 20 through the protective structure 10 and the battery pack 30 in time, reducing the intrusion of the front panel 23, thereby protecting the passenger compartment.

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

[0085] Further, the dimension H2 of the second gap B along the second direction X satisfies: 20 mm ≤ H2 ≤ 40 mm. Exemplarily, the dimension 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 subframe 40 can be transmitted backward in time after being transmitted to the protective structure 10; at the same time, it can ensure that there is a certain buffer space between the protective structure 10 and the battery pack 30.

[0087] Alternatively, if Figure 4 As shown, the vehicle body 20 includes a dash panel 23 and a dash panel cross beam 231 , the dash panel 23 is connected to the dash panel cross beam 231 , and one end of the protective structure 10 facing the first mounting portion 201 is connected to the dash panel cross beam 231 .

[0088] In the embodiment of the present application, the vehicle body 20 is provided with a front panel 23 and a front panel cross beam 231. The front panel 23 is connected to the front panel cross beam 231. A certain cavity can be enclosed between the front panel 23 and the front panel cross beam 231 for arranging the front cabin structure of the vehicle, and then the protective structure 10 is connected to the front panel cross beam 231 to realize the installation and fixation of the protective structure 10 and the vehicle body 20.

[0089] Alternatively, if Figure 3 As shown, the vehicle further includes a subframe 40 , which is connected to the first mounting portion 201 , and a gap exists between the subframe 40 and at least a portion of the protective structure 10 .

[0090] In the embodiment of the present application, the vehicle includes a subframe 40, which is connected to the first mounting portion 201 of the vehicle body 20. There is at least a partial gap between the subframe 40 and the protective structure 10 to reserve a certain amount of retreat failure space for the subframe 40. At the same time, by setting the first gap A, it is also possible to avoid rigid friction between the protective structure 10 and the subframe 40 during driving of the vehicle, thereby preventing abnormal noise or local damage.

[0091] Alternatively, if Figure 6 As shown, at least one first mounting hole 401 is provided in the sub-frame 40, and the sub-frame 40 is connected to the first mounting portion 201 through the first mounting hole 401. A plurality of second mounting holes 110 are provided at one end of the protective structure 10 close to the first mounting portion 201; along the first direction Y, the second mounting holes 110 are staggered with the first mounting holes 401.

[0092] In the embodiment of the present application, a first mounting hole 401 is provided in the sub-frame 40, and the first mounting hole 401 is used for connecting and fixing the sub-frame 40 with the first mounting portion 201 of the vehicle body 20. At the same time, a plurality of second mounting holes 110 are provided at one end of the protective structure 10 close to the first mounting portion 201, and the protective structure 10 can be connected and fixed with the vehicle body 20 through the second mounting holes 110. Furthermore, the second mounting holes 110 are staggered from the first mounting holes 401, so that the structural layout design of the second mounting holes 110 and the first mounting holes 401 is convenient to avoid mutual interference during installation, and it can also ensure that the protective structure 10 has a certain degree of variability in the portion corresponding to the first mounting hole 401, so as to absorb the impact force transmitted by the sub-frame 40 and play a buffering role.

[0093] The second mounting hole 110 and the first mounting hole 401 being staggered along the first direction Y means that the orthographic projections of the second mounting hole 110 and the first mounting hole 401 along the length direction of the vehicle (ie, the second direction X) do not overlap with each other.

[0094] Alternatively, if Figure 6As shown, the plurality of second mounting holes 110 include at least one preset hole 110a, and the distance D1 between the preset hole 110a and the first mounting hole 401 along the first direction Y satisfies: 50mm≤D1≤100mm. Exemplarily, the distance D1 between the preset hole 110a and the first mounting hole 401 along the first direction Y can be set to: 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc.

[0095] It should be noted that the distance D1 refers to the distance from the center of the preset hole 110 a to the center of the first mounting hole 401 .

[0096] In the embodiment of the present application, the distance between at least one preset hole 110a and the first mounting hole 401 is set to be between 50mm and 100mm, so as to ensure that the connection strength between the protective structure 10 and the vehicle body 20 is ensured, and at the same time, ensure that the protective structure 10 has a certain degree of variability in the portion corresponding to the first mounting hole 401, so as to absorb the impact force transmitted by the subframe 40 and play a buffering role.

[0097] It can be understood that the vehicle body 20 includes a front panel 23 and a front panel cross beam 231, the front panel 23 is connected to the front panel cross beam 231, and the protective structure 10 is connected to the front panel cross beam 231 through the second mounting hole 110. When impacted by external force, the protective structure 10 is not easily deformed in the portion corresponding to the second mounting hole 110 because it is in a connected state, while the portion outside the second mounting hole 110 is in a free state and is easily deformed.

[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 sub-frame 40 is impacted, the impact force is transmitted to the protective structure 10 through the portion of the sub-frame 40 where the first mounting hole 401 is located, and the corresponding portion of the protective structure 10 is deformed to absorb energy.

[0099] If the second mounting hole 110 is too close to the first mounting hole 401, it is not only inconvenient to design and install the second mounting hole 110 and the first mounting hole 401, but also the corresponding part of the protective structure 10 and the first mounting hole 401 is not easy to deform and cannot play an effective energy absorption role. If the second mounting hole 110 is too far away from the first mounting hole 401, when the impact force on the sub-frame 40 is transmitted to the protective structure 10, the corresponding part of the protective structure 10 is too deformed and cannot play an effective supporting role for the sub-frame 40.

[0100] Alternatively, if Figure 3 and Figure 7As shown, the protective 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 to the front panel cross 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 to the battery pack mounting beam 21, or to the floor 22, or to the battery pack 30.

[0101] In the embodiment of the present application, a first connection portion 11 and a second connection portion 12 are respectively provided at both ends of the protective structure 10 so as to be connected to the vehicle body 20 through the first connection portion 11 and the second connection portion 12 to achieve installation and fixation of the protective structure 10. A reinforcement portion 13 is provided between the first connection portion 11 and the second connection portion 12 to improve the overall structural strength of the protective structure 10. The protective structure 10 can be used to transmit the collision force exerted on the sub-frame 40 to support the sub-frame 40.

[0102] Specifically, the vehicle body 20 may include a dash panel 23 and a dash panel cross beam 231 , which are connected, and the first connecting portion 11 of the protective structure 10 may be connected to the dash panel cross beam 231 to achieve installation and fixation of one end of the protective structure 10 .

[0103] Furthermore, the vehicle body 20 further includes a floor 22. When a battery pack mounting beam 21 is provided below the floor 22, the second connection portion 12 of the protective structure 10 can be connected to the battery pack mounting beam 21. When a battery pack mounting beam 21 is not provided below the floor 22, the second connection portion 12 can be directly connected and fixed to the floor 22. At this time, the battery pack 30 can be installed on the floor 22, or the battery pack 30 can be connected and fixed to the second connection portion 12 of the protective structure 10. The specific connection structure can be flexibly set according to actual conditions and is not limited here.

[0104] Alternatively, if Figure 3 As shown, a hollow structure 101 is provided in the reinforcement portion 13. By providing the hollow structure 101 in the reinforcement portion 13 of the protective structure 10, when the protective structure 10 is subjected to impact force, it can absorb energy by deformation, thereby playing a supporting role for the subframe 40 and a protective role for the battery pack 30.

[0105] In some embodiments, Figure 3 As shown, the first connection part 11 and the second connection part 12 are both hollow structures, and the cross-sections of the first connection part 11 and the second connection part 12 may be "U"-shaped. The wall thickness of the first connection part 11 and the second connection part 12 is greater than or equal to the wall thickness of the outer shell of the reinforcement part 13, so as to increase the strength of the first connection part 11 and the second connection part 12.

[0106] For example, the wall thickness of the first connection part 11 and the second connection part 12 can be set to 2.5mm-3mm; the wall thickness of the outer shell of the reinforcement part 13 can be set to 2mm-2.5mm. Of course, the specific structural dimensions can be flexibly adjusted according to actual design requirements and are not limited here.

[0107] In other embodiments, the first connection portion 11 and the second connection portion 12 may also be configured as a solid structure to increase the structural strength of the first connection portion 11 and the second connection portion 12. The size and shape structure of the first connection portion 11 and the second connection portion 12 may be determined according to the structural design requirements of the vehicle, and this application does not limit this.

[0108] Alternatively, if Figure 4 and Figure 8 As shown, the protective structure 10 is further provided with a reinforcing rib 132 , the reinforcing portion 13 is provided with a cavity, and the reinforcing rib 132 is arranged in the cavity to form a hollow structure 101 .

[0109] In the embodiment of the present application, a cavity is provided in the reinforcing portion 13 so that the reinforcing portion 13 has a certain variable space, thereby being able to absorb energy and reduce the collision force transmitted to the battery pack 30. At the same time, reinforcing ribs 132 are provided in the cavity of the reinforcing portion 13 to strengthen the reinforcing portion 13 and improve the overall structural strength of the reinforcing portion 13.

[0110] Alternatively, if Figure 8 and Fig. 9 As shown, the reinforcing rib 132 includes a first reinforcing rib 1321, which is connected to the first position 131a of the reinforcing portion 13, wherein the first position 131a is suitable for corresponding to the bending transition of the front panel 23, and the other end of the first reinforcing rib 1321 extends along a third direction Z in a direction away from the front panel 23, wherein the third direction Z is the height direction of the vehicle.

[0111] In the embodiment of the present application, a first reinforcing rib 1321 is provided in the cavity of the reinforcing portion 13, and the first reinforcing rib 1321 is connected to the first position 131a of the reinforcing portion 13 to reinforce the first position 131a of the reinforcing portion 13. When the protective structure 10 is installed on the vehicle, the first position 131a of the reinforcing portion 13 corresponds to the bending transition portion of the front panel 23, thereby reinforcing the bending transition portion of the front panel 23.

[0112] It can be understood that the vehicle body 20 includes a front panel 23, a portion of which extends toward the rear of the vehicle and is connected to the floor 22, and a portion of the front panel 23 extends obliquely upward toward the front of the vehicle to isolate the front cabin and the passenger cabin of the vehicle, thereby forming a bending transition between the front and rear parts of the front panel 23. When the vehicle is impacted by a collision, the collision force is transmitted to the front panel 23, and stress concentration occurs at the bending transition of the front panel 23, which is prone to deformation and damage.

[0113] Correspondingly, the position of the reinforcement portion 13 corresponding to the bending transition of the front panel 23 is also a stress concentration area. Therefore, in the present application, a first reinforcement rib 1321 is provided in the cavity of the reinforcement portion 13 so that the first reinforcement rib 1321 is connected to the first position 131a of the reinforcement portion 13 to reinforce the first position 131a of the reinforcement portion 13, thereby enhancing the supporting and protecting effect of the protective structure 10 on the bending transition of the front panel 23.

[0114] Specifically, 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 in a direction away from the front panel 23. It should be noted that the extension direction of the first reinforcing rib 1321 can be parallel to the third direction Z; or it can be at a certain angle with the third direction Z, and the angle is an acute angle. 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 here.

[0115] Alternatively, if Figure 8 and Fig. 9 As shown, the reinforcing rib 132 also includes a second reinforcing rib 1322, one end of which is connected to the first position 131a of the reinforcing portion 13, and the other end of the second reinforcing rib 1322 extends along a third direction Z in a direction away from the first position 131a, and the extension directions of the first reinforcing rib 1321 and the second reinforcing rib 1322 intersect.

[0116] In the embodiment of the present application, the first reinforcing rib 1321 and the second reinforcing rib 1322 are simultaneously arranged in the cavity of the reinforcing portion 13, and the first reinforcing rib 1321 and the second reinforcing rib 1322 are both connected to the first position 131a of the reinforcing portion 13, so as to reinforce the first position 131a of the reinforcing portion 13. 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 reinforcement effect.

[0117] Specifically, Figure 8As shown, 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 a direction away from the front panel 23 and close to the subframe 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 in a direction away from the front panel 23 and close to the battery pack 30.

[0118] Alternatively, if Figure 8 As shown, the reinforcing rib 132 further includes a third reinforcing rib 1323, and the third reinforcing rib 1323 is cross-connected with the first reinforcing rib 1321. The cross-connection means that the extension direction of the third reinforcing rib 1323 intersects with the extension direction of the first reinforcing rib 1321.

[0119] In the embodiment of the present application, a third reinforcing rib 1323 is provided in the cavity of the reinforcing portion 13 so that the third reinforcing rib 1323 is cross-connected with the first reinforcing rib 1321 , that is, a cross-support structure is formed by the third reinforcing rib 1323 and the first reinforcing rib 1321 , thereby enhancing the reinforcing effect of the reinforcing portion 13 .

[0120] Alternatively, if Figure 8 As shown, the reinforcing rib 132 further includes a fourth reinforcing rib 1324, and the fourth reinforcing rib 1324 is cross-connected with the second reinforcing rib 1322. The cross-connection means that the extension direction of the fourth reinforcing rib 1324 intersects with the extension direction of the second reinforcing rib 1322.

[0121] In the embodiment of the present application, by arranging the fourth reinforcing rib 1324 in the cavity of the reinforcing portion 13, 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, which can enhance the reinforcing effect of the reinforcing portion 13.

[0122] In some embodiments, one or more third reinforcing ribs 1323 and fourth reinforcing ribs 1324 may be provided, and the specific number may 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, reinforcing ribs 132 of other structures may also be provided in the cavity of the reinforcing portion 13 to enhance the reinforcing effect of the reinforcing portion 13. The specific structural arrangement may be flexibly arranged according to actual needs and is not limited here.

[0124] In addition, the thickness of the outer shell of the reinforcement part 13 is greater than or equal to the thickness of the reinforcement rib 132, thereby improving the strength of the outer shell of the reinforcement part 13. The specific thickness can be flexibly set according to actual needs and is not limited here.

[0125] Alternatively, if Figure 6As shown, 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 holes 110 are used to be connected to the front wall cross beam 231 .

[0126] In the embodiment of the present application, a plurality of second mounting holes 110 arranged at intervals are provided in the first connecting portion 11 so that during installation, fasteners can be passed through the second mounting holes 110 to connect with the front panel cross beam 231 of the vehicle body 20, thereby achieving installation and fixation of the protective structure 10.

[0127] In some embodiments, a plurality of second mounting holes 110 may be arranged at equal intervals. In this way, the connection points between the first connecting portion 11 and the dash panel cross beam 231 may be more evenly distributed, thereby ensuring the connection strength between different positions of the protective structure 10 and the dash panel cross beam 231 .

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

[0129] In the present application, by setting a reasonable value range of the spacing M1 between two adjacent second mounting holes 110, it is avoided that the spacing of the second mounting holes 110 is too small, so that the number of second mounting holes 110 required to be set in the first connecting portion 11 is too large, which will not only occupy more installation space, but also increase the difficulty of installation and disassembly. If the spacing of the second mounting holes 110 is too large, the number of second mounting holes 110 set in the first connecting portion 11 is too small, so that the connection strength between the first connecting portion 11 and the front panel 23 is insufficient, when the vehicle is hit, the protective structure 10 is easy to fall off or deform greatly, and it cannot play an effective supporting role for the subframe 40 and an effective protection role for the battery pack 30.

[0130] Alternatively, if Figure 6 As shown, the second connection portion 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 embodiment of the present application, a plurality of third mounting holes 120 arranged at intervals are provided in the second connecting portion 12 so that during installation, fasteners can be passed through the third mounting holes 120 to connect to the battery pack mounting beam 21 or the floor 22, thereby achieving connection and fixation between the protective structure 10 and the battery pack mounting beam 21 or the floor 22.

[0132] In some embodiments, a plurality of third mounting holes 120 may be arranged at equal intervals. In this way, the connection points between the second connecting portion 12 and the battery pack mounting beam 21 or the floor 22 may be more evenly distributed, thereby ensuring the connection strength between the protective structure 10 and the battery pack mounting beam 21 or the floor 22 at different positions.

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

[0134] In the embodiment of the present application, by setting a reasonable value range of the spacing M2 between two adjacent third mounting holes 120, it is avoided that the spacing of the third mounting holes 120 is too small, so that the number of the third mounting holes 120 set in the second connecting portion 12 is too large, which will not only occupy more installation space, but also increase the difficulty of installation and disassembly, and is not convenient for actual use. If the spacing of the third mounting holes 120 is too large, the number of the third mounting holes 120 set in the second mounting portion 202 is too small, resulting in insufficient connection strength between the first connecting portion 11 and the front panel 23. When the vehicle is hit, the protective structure 10 is prone to fall off or deform greatly, and cannot play an effective supporting role for the subframe 40 and an effective protection role for the battery pack 30.

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

[0136] Optionally, 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 the embodiment of the present application, the number S1 of the second mounting holes 110 provided in the first connection portion 11 is determined based on the length L of the protective structure 10 along the first direction Y, or the number S1 of the second mounting holes 110 is set to be greater than or equal to 4. This ensures that a reasonable number of second mounting holes 110 are provided in the first connection portion 11 to ensure the connection strength between the first connection portion 11 and the dash panel cross member 231.

[0138] Optionally, 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 the embodiment of the present application, the number S2 of the third mounting holes 120 provided in the second connection 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 set to be greater than or equal to 4. This ensures that a reasonable number of third mounting holes 120 are provided in the second connection portion 12 to ensure the connection strength between the second connection portion 12 and the crossbeam of the battery pack 30 or the floor 22.

[0140] Alternatively, if Figure 3 As shown, the height of the first connection portion 11 along the third direction Z is greater than or equal to 15 mm, and the third direction Z is the height direction of the vehicle. For example, the height of the first connection portion 11 along the third direction Z can be set to 15 mm, 16 mm, 17 mm, 18 mm, 20 mm, 30 mm, etc.

[0141] In the embodiment of the present application, the height of the first connection portion 11 along the third direction Z is set to be greater than or equal to 15 mm to ensure that the first connection portion 11 has a certain height. Therefore, when the sub-frame 40 is collided, the collision force can be transmitted from the sub-frame 40 to the protective structure 10 through the first connection portion 11, thereby ensuring that the protective structure 10 can support the sub-frame 40.

[0142] In some embodiments, Figure 4 and Figure 8 As shown, the first connection portion 11 and the reinforcement portion 13 are integrally formed. By setting the first connection portion 11 and the reinforcement portion 13 as an integrally formed part, the structural strength of the first connection portion 11 and the reinforcement portion 13 is improved, and the actual processing is also convenient.

[0143] In other embodiments, Figure 4 and Figure 8 As shown, the second connection part 12 and the reinforcement part 13 are an integrally formed part. By setting the second connection part 12 and the reinforcement part 13 as an integrally formed part, the structural strength of the second connection part 12 and the reinforcement part 13 is improved, and the actual processing is also convenient.

[0144] In some other embodiments, Figure 4 and Figure 8 As shown, the first connection part 11, the second connection part 12 and the reinforcement part 13 are integrally formed. By setting the first connection part 11, the second connection part 12 and the reinforcement part 13 as an integrally formed part, the overall structural strength of the protective structure 10 is improved, and the processing and manufacturing of the protective structure 10 is also facilitated.

[0145] In other embodiments, the protective structure 10 may be made of aluminum extrusion molded parts, which can ensure that the protective structure 10 has a certain structural strength while also reducing the weight of the protective structure 10 and having a lower cost of use.

[0146] Of course, the protective structure 10 can also be made of other materials such as aluminum alloy, composite materials, etc. Technical personnel in this field can flexibly choose according to actual needs, and no limitation is made here.

[0147] Alternatively, if Figure 4 and Figure 8 As shown, the height direction of the vehicle is the third direction Z. Along the third direction Z, the surface of the first connection portion 11 facing away from the vehicle body 20 is higher than the surface of the second connection portion 12 facing away from the vehicle body 20 .

[0148] Specifically, along the height direction of the vehicle, the surface of the first connection part 11 facing away from the vehicle body 20 is higher than the surface of the second connection part 12 facing away from the vehicle body 20, that is, the lower surface of the first connection part 11 is higher than the lower surface of the second connection part 12, so as to form a height difference between the lower surface of the first connection part 11 and the lower surface of the second connection part 12, so that after the collision force of the subframe 40 is transmitted to the protective structure 10, the protective structure 10 can maintain a good crushing deformation mode, thereby being able to play an effective supporting and protective role.

[0149] Alternatively, if Figure 4 and Figure 8 As shown, from the first connection portion 11 to the second connection portion 12 , the size of the reinforcement portion 13 along the third direction Z gradually increases, and the third direction Z is the height direction of the vehicle.

[0150] In the embodiment of the present application, from the first connection part 11 to the second connection part 12, the size of the reinforcement part 13 along the third direction Z is gradually increased, so that when the protective structure 10 is subjected to collision force, the side of the reinforcement part 13 close to the first connection part 11 is deformed first, and then the impact force is gradually transmitted to the side close to the second connection part 12, so that the protective structure 10 maintains a good crushing deformation mode and can play an effective supporting and protective role. In addition, by setting the size of the reinforcement part 13 to be gradually increased, the phenomenon of stress concentration caused by sudden changes in the local cross section of the reinforcement part 13 can also be avoided.

[0151] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0152] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the claims and their equivalents.
