[0031] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0032] The following is for reference. Figures 1-4 The front bulkhead assembly 100 according to an embodiment of the present utility model is described. The front bulkhead assembly 100 can increase the transmission path of collision force, improve the reliability of transmission and dissipation of collision force, and effectively prevent the engine from intruding into the passenger compartment, thereby improving the safety of vehicle use.

[0033] like Figures 1-4 As shown, a front bulkhead assembly 100 according to one embodiment of the present invention includes: two front bulkhead longitudinal beams 1 and an engine cantilever 2.

[0034] Two front longitudinal beams 1 are spaced apart laterally along the vehicle and define an engine mounting space 11. The front longitudinal beams 1 are provided with engine mounting seats 12. Engine cantilever 2 is used to connect to the engine. The engine cantilever 2 and the engine mounting seat 12 are inserted into each other laterally along the vehicle. The front longitudinal beams 1 have a first crumple position 13. The front longitudinal beams 1 are constructed such that when subjected to a frontal collision, the first crumple position 13 crumples outward so that the engine cantilever 2 and the engine mounting seat 12 are separated from each other.

[0035] Specifically, the front longitudinal beam 1 is an important component of the vehicle body structure. It is used to absorb and dissipate the huge energy generated by the collision through its own deformation (such as bending, wrinkling, etc.) when the vehicle is subjected to a frontal collision, thereby reducing the impact on the occupants.

[0036] It should be noted that the front part of the front longitudinal beam 1 is connected to the rear side of the energy-absorbing box via the transition structure 3, and the rear part is connected to the front side of the front structure 4. The energy-absorbing box is connected to the rear side of the anti-collision beam. This allows the anti-collision beam, energy-absorbing box, front longitudinal beam 1, and front structure 4 to be connected sequentially from front to back, forming a collision force transmission path. When the vehicle is subjected to a frontal collision, the front longitudinal beam 1 can further transmit the collision force transmitted from the anti-collision beam to the energy-absorbing box to the front structure 4. In this way, the anti-collision beam, energy-absorbing box, front longitudinal beam 1, and front structure 4 can be used together to absorb and dissipate the collision force, reducing the possibility of the collision force being transmitted into the passenger compartment.

[0037] The front longitudinal beam 1 is constructed to extend along the front-rear direction of the vehicle, which gives the front longitudinal beam 1 a certain length and improves the reliability of the front longitudinal beam 1 in absorbing and dissipating the collision force. There are two front longitudinal beams 1, which can be used together to transmit and dissipate the collision force, which can improve the reliability of the transmission and dissipation of the collision force. Moreover, the two front longitudinal beams 1 are distributed laterally along the vehicle, which can increase the transmission path of the collision force. Thus, when the vehicle is hit by a frontal collision, the collision force can be dispersed to other parts of the vehicle body along different paths, effectively reducing the possibility of the collision force being transmitted into the passenger compartment.

[0038] It should be noted that the two front longitudinal beams 1 are arranged symmetrically with respect to the longitudinal direction of the vehicle. The following description will take the front longitudinal beam 1 located on the left side of the vehicle as an example.

[0039] Furthermore, the two front longitudinal beams 1 define the engine mounting space 11, which provides space for the engine to be installed. This ensures that there is a certain distance between the two front longitudinal beams 1 to avoid interference between the engine and the front longitudinal beams 1, thus preventing a decrease in their respective operational reliability. The front longitudinal beams 1 are equipped with engine mounting seats 12, which are used to fix the engine. By placing the engine mounting seats 12 on the front longitudinal beams 1, the engine mounting seats 12 can be connected to the front longitudinal beams 1 to fix the engine mounting seats 12, thereby improving the reliability of the engine mounting seats 12 in fixing the engine.

[0040] Meanwhile, the engine cantilever 2 is used to connect to the engine to connect the engine with other components. The engine cantilever 2 and the engine mounting base 12 are inserted and matched along the lateral side of the vehicle, so that the engine cantilever 2 can be set on the lateral inner side of the engine mounting base 12, and the engine cantilever 2 can be connected to the engine mounting base 12 by insertion and matching. In other words, the engine can be connected to the engine mounting base 12 through the engine cantilever 2 to realize the installation and fixation of the engine on the vehicle and ensure the reliable operation of the engine.

[0041] In this application, a insertion groove can be provided in one of the engine cantilever 2 and the engine mounting seat 12, and a insertion protrusion can be provided in the other. At least part of the insertion protrusion can extend into the insertion groove and engage with it, thereby realizing the insertion engagement between the engine cantilever 2 and the engine mounting seat 12. In addition, the inner side in this application is the side facing the vehicle centerline, and the outer side is the side away from the vehicle centerline.

[0042] Furthermore, the front longitudinal beam 1 has a first crumple position 13, which is used to allow the front longitudinal beam 1 to deform and crumple when subjected to force, so as to reliably absorb and dissipate the collision force. The front longitudinal beam 1 is constructed such that the first crumple position 13 crums outward when subjected to a frontal collision. That is, when the vehicle is subjected to a frontal collision, the front longitudinal beam 1 can deform and crumple outward at the first crumple position 13. When the front longitudinal beam 1 deforms and crumples outward at the first crumple position 13, at least a part of the front longitudinal beam 1 can drive the engine mount 12 to move outward. When the engine mount 12 moves outward a certain distance, the engine mount 12 and the engine cantilever 2 are disengaged. At this time, the engine and the engine cantilever 2 will fall downward under the action of gravity, which can prevent the collision force from being transmitted to the front crossbeam 5 through the engine, thereby preventing the engine from intruding into the passenger compartment.

[0043] It should be noted that an induced collapse structure can be set at the first collapse position 13, so that the front longitudinal beam 1 can deform at the first collapse position 13 in a predetermined manner, thereby effectively reducing the possibility of the engine intruding into the passenger compartment.

[0044] According to the front bulkhead assembly 100 of this utility model embodiment, by setting two front bulkhead longitudinal beams 1, the transmission path of collision force can be increased, and the reliability of transmitting and dissipating collision force can be improved. Furthermore, the front bulkhead longitudinal beams 1 are constructed such that the first crumple position 13 crumples outward when subjected to a frontal collision, so that the engine cantilever 2 and the engine mounting seat 12 can be separated from each other, which can effectively prevent the engine from intruding into the passenger compartment and improve the vehicle's safety.

[0045] In some embodiments, the engine mounting base 12 has a suspension space 121 that opens toward the engine mounting space 11, and the engine cantilever 2 includes a plug-in mounting portion 21 that protrudes toward the suspension space 121 and is plugged into the suspension space 121.

[0046] Specifically, the engine mounting base 12 is plugged into the engine cantilever 2. The engine mounting base 12 has a suspension space 121, and the engine cantilever 2 includes a plug-in mounting portion 21. The suspension space 121 has a certain volume to accommodate the plug-in mounting portion 21. By configuring the suspension space 121 to be open towards the engine mounting space 11, the suspension space 121 is open towards the engine cantilever 2. Furthermore, by protruding the plug-in mounting portion 21 towards the suspension space 121, the plug-in mounting portion 21 can be brought closer to the suspension space 121, thus facilitating the insertion of the plug-in mounting portion 21 into the suspension space 121. This allows the suspension space 121 and the plug-in mounting portion 21 to engage, thereby achieving the plug-in connection between the engine mounting base 12 and the engine cantilever 2. This plug-in connection method is simple, reliable, and easy to operate.

[0047] In some embodiments, an elastic pad 122 is provided in the suspension space 121, and the elastic pad 122 is disposed between the plug-in mounting part 21 and the inner wall of the suspension space 121.

[0048] Specifically, the plug-in mounting part 21 extends into the suspension space 121 and engages with it. An elastic rubber pad 122 is provided in the suspension space 121. The elastic rubber pad 122 is located between the plug-in mounting part 21 and the inner wall of the suspension space 121, that is, between the engine mounting seat 12 and the engine cantilever 2. Thus, the elastic rubber pad 122 can be fixedly connected to the engine mounting seat 12. The plug-in mounting part 21 is inserted into the elastic rubber pad 122, so that the connection between the engine mounting seat 12 and the engine is realized through the elastic rubber pad 122 and the engine cantilever 2, thereby realizing the installation and fixation of the engine.

[0049] It should also be noted that the elastic pad 122 can be constructed as a hard plastic block, which can give the elastic pad 122 a certain elasticity. In this way, the elastic pad 122 can form a soft connection between the engine mounting base 12 and the engine cantilever 2, so that the elastic pad 122 can play the role of supporting and buffering the vibration of the engine.

[0050] Therefore, when the vehicle is subjected to a frontal collision, the front longitudinal beam 1 collapses outward at the first crumple position 13. At this time, at least a part of the front longitudinal beam 1 can drive the engine mount 12 to move outward, which can be deformed into a drawer shape. When the engine mount 12 moves outward a certain distance, the plug-in mounting part 21 and the elastic rubber pad 122 are plugged and separated, so that the engine cantilever 2 can fall down with the engine under the action of gravity, which can effectively prevent the engine from intruding into the passenger compartment.

[0051] In some embodiments, the engine mounting base 12 includes a base body 123 and at least one connecting flange 124. The base body 123 is hollow and forms a suspension space 121. The connecting flange 124 is connected to the base body 123 and is detachably connected to the front longitudinal beam 1.

[0052] Specifically, the engine mounting base 12 is fixedly connected to the front longitudinal beam 1. The engine mounting base 12 includes a base body 123 and at least one connecting flange 124. Connecting the base body 123 and the connecting flange 124 makes the engine mounting base 12 an integral structure, which can improve the structural strength and operational reliability of the engine mounting base 12. Furthermore, the interior of the base body 123 is hollow, forming a suspension space 121. When constructing the engine mounting base 12, the interior of the base body 123 can be hollowed out to form the suspension space 121. The suspension space 121 has a certain volume, which can be used to fix the elastic rubber pad 122 within the suspension space 121 to achieve the installation of the elastic rubber pad 122 and ensure the reliable operation of the elastic rubber pad 122.

[0053] Meanwhile, the connecting flange 124 is connected to the front longitudinal beam 1, meaning the engine mounting base 12 can be connected to the front longitudinal beam 1 via the connecting flange 124 to achieve the installation of the engine mounting base 12. Furthermore, by setting the connecting flange 124, the contact area between the engine mounting base 12 and the front longitudinal beam 1 can be increased, improving the reliability of the connection between the two. There can be at least one connecting flange 124, meaning the number of connecting flanges 124 can be one, two, three, or more, allowing at least one connecting flange 124 to be connected to the front longitudinal beam 1 to achieve a reliable connection. Moreover, the connecting flange 124 and the front longitudinal beam 1 are detachably connected, for example, through snap-fit ​​or connectors. This detachable connection method facilitates connecting or separating the connecting flange 124 from the front longitudinal beam 1, thus facilitating the installation or removal of the engine mounting base 12. This allows for easy replacement of the engine mounting base 12 when it is damaged, reducing installation costs.

[0054] In some embodiments, there are two connecting flanges 124, and the two connecting flanges 124 are connected to both ends of the longitudinal direction of the seat body 123, and the two connecting flanges 124 are respectively connected to the front longitudinal beam 1 through a first connector 125.

[0055] Specifically, the connecting flange 124 is used to connect with the front longitudinal beam 1. By setting two connecting flanges 124, both connecting flanges 124 can be connected to the front longitudinal beam 1, which can improve the connection reliability between the engine mounting bracket 12 and the front longitudinal beam 1. Furthermore, by connecting the two connecting flanges 124 to both ends in the longitudinal direction of the mounting body 123, the two connecting flanges 124 can be distributed separately along the longitudinal direction of the vehicle. Thus, when installing the engine mounting bracket 12, the engine mounting bracket 12 can be connected to the front longitudinal beam 1 from two positions at the same time through the two connecting flanges 124, which can improve the connection stability between the engine mounting bracket 12 and the front longitudinal beam 1.

[0056] Furthermore, by connecting the two connecting flanges 124 to the front longitudinal beam 1 via a first connecting member 125, there are two first connecting members 125. By setting the two first connecting members 125 in a one-to-one correspondence with the two connecting flanges 124, each first connecting member 125 can be simultaneously inserted through its corresponding connecting flange 124 and the front longitudinal beam 1, thus achieving the connection between the connecting flange 124 and the front longitudinal beam 1, and consequently, the connection between the engine mounting base 12 and the front longitudinal beam 1, ensuring reliable installation and fixation of the engine mounting base 12. The first connecting member 125 can be a bolt.

[0057] It should be noted that, as Figure 4 As shown, a connecting hole 17 can be made on the front longitudinal beam 1 at the position corresponding to the connecting flange 124. The first connecting piece 125 can be passed through the connecting hole 17 and the connecting flange 124 at the same time to realize the connection between the engine mounting base 12 and the front longitudinal beam 1.

[0058] In some embodiments, the engine cantilever 2 further includes a cantilever body 22, with a plug-in mounting portion 21 connected to the outside of the cantilever body 22. The cantilever body 22 is provided with at least one connecting portion 221 for detachably connecting to the engine.

[0059] Specifically, the engine cantilever 2 includes a plug-in mounting part 21 and a cantilever body 22. By connecting the plug-in mounting part 21 to the outside of the cantilever body 22, the plug-in mounting part 21 can be connected to the cantilever body 22, making the engine cantilever 2 an integral structure. This can improve the structural strength and operational reliability of the engine cantilever 2. Furthermore, the plug-in mounting part 21 can protrude toward the suspension space 121 so that it can be plugged into the suspension space 121 and engaged with the elastic rubber pad 122 located in the suspension space 121, thereby realizing the connection between the engine cantilever 2 and the engine mounting base 12.

[0060] Furthermore, the engine cantilever 2 is fixedly connected to the engine, and the cantilever body 22 is provided with at least one connecting part 221. The connecting part 221 is used to connect the engine cantilever 2 to the engine for installation and fixation. There is at least one connecting part 221, that is, the number of connecting parts 221 can be one, two, three or more. At least one connecting part 221 can be connected to the engine to achieve reliable installation of the engine. Moreover, the connecting part 221 is detachably connected to the engine, such as by snap-fit ​​or connector. The detachable connection method makes it easy to connect or separate the connecting part 221 from the engine, which facilitates the installation or removal of the engine. This makes it easy to replace the engine when it is damaged, which helps to reduce the installation cost.

[0061] In some embodiments, there are multiple connecting portions 221, and the multiple connecting portions 221 are distributed longitudinally spaced apart on the cantilever body 22; and / or, the connecting portions 221 are adapted to be connected to the engine via a second connector 222, and the connecting portions 221 are formed with mounting grooves 223 for accommodating at least a portion of the second connector 222.

[0062] Specifically, the connecting part 221 is used to connect to the engine. Multiple connecting parts 221 can be provided, that is, the number of connecting parts 221 can be two, three or more, so that multiple connecting parts 221 can be connected to the engine at the same time, which can improve the connection reliability between the engine cantilever 2 and the engine. Moreover, the multiple connecting parts 221 are distributed longitudinally and spaced apart on the cantilever body 22, so that when the engine is installed, the engine cantilever 2 can be connected to the engine from multiple positions at the same time through multiple connecting parts 221, which can improve the connection stability between the engine cantilever 2 and the engine.

[0063] Furthermore, the connecting portion 221 is adapted to be connected to the engine via the second connecting member 222, meaning there can be multiple second connecting members 222. These multiple second connecting members 222 are arranged one-to-one with multiple connecting portions 221, allowing each second connecting member 222 to simultaneously pass through its corresponding connecting portion 221 and the engine. This achieves the connection between the connecting portion 221 and the engine, thus connecting the engine cantilever 2 to the engine, ensuring reliable installation and fixation of the engine. The second connecting member 222 can be a bolt.

[0064] Furthermore, the connecting portion 221 is formed with a mounting groove 223 for accommodating at least a portion of the second connector 222. The mounting groove 223 is recessed downward so that when the connecting portion 221 and the engine are connected by the second connector 222, at least a portion of the second connector 222 can be located within the mounting groove 223. This allows at least a portion of the second connector 222 to overlap with the vertical space occupied by the mounting groove 223 in the vehicle, thus preventing the second connector 222 from extending too far and interfering with other components on the vehicle.

[0065] In such Figure 2 In the embodiment shown, there are three connecting portions 221 and three second connecting members 222, and the three connecting portions 221 are spaced apart along the longitudinal direction of the vehicle. Thus, the three connecting portions 221 can be connected to the engine at three locations simultaneously through the three second connecting members 222, which can improve the reliability and stability of the connection between the engine cantilever 2 and the engine. At least one connecting portion 221 is formed with a mounting groove 223 to accommodate at least a portion of the second connecting member 222 in order to avoid other components on the vehicle.

[0066] In some embodiments, the front longitudinal beam 1 further has a second crumple position 14 and a third crumple position 15 spaced apart in the front-rear direction, a first crumple position 13 located between the second crumple position 14 and the third crumple position 15, and the front longitudinal beam 1 is configured such that the second crumple position 14 and the third crumple position 15 crumple inward when subjected to a frontal collision.

[0067] Specifically, the front longitudinal beam 1 also has a second crumple position 14 and a third crumple position 15. The second crumple position 14 and the third crumple position 15 are used to allow the front longitudinal beam 1 to deform and crumple when subjected to force, so as to reliably absorb and dissipate the collision force. The second crumple position 14 and the third crumple position 15 are spaced apart in the front-rear direction, so that the front longitudinal beam 1 can crumple at different positions simultaneously when subjected to force, which can improve the reliability of absorbing and dissipating the collision force. Moreover, the second crumple position 14 can be set in front of the third crumple position 15, and the first crumple position 13 can be set between the second crumple position 14 and the third crumple position 15. The second crumple position 14, the first crumple position 13 and the third crumple position 15 are distributed sequentially in the front-rear direction, so that the front longitudinal beam 1 can deform and crumple at three positions simultaneously when subjected to force, which can effectively improve the reliability of absorbing and dissipating the collision force, and effectively reduce the transmission of the collision force into the passenger compartment.

[0068] Specifically, the front longitudinal beam 1 is configured such that, upon a frontal collision, the second crumple position 14 and the third crumple position 15 both crumple inwards, while the first crumple position 13 crumples outwards. In other words, when the vehicle is subjected to a frontal collision, the crumple direction of the front longitudinal beam 1 at the second crumple position 14 and the third crumple position 15 is opposite to the crumple direction at the first crumple position 13. This allows at least a portion of the front longitudinal beam 1 to bend in a W-shape, inducing crumple at the first crumple position 13, the second crumple position 14, and the third crumple position 15, respectively. This allows at least a portion of the front longitudinal beam 1 to deform in a predetermined manner during the collision, thereby absorbing collision energy to a greater extent and effectively reducing the possibility of the collision force being transmitted into the passenger compartment.

[0069] It should be noted that at least a portion of the front longitudinal beam 1 of this application can deform and collapse when the vehicle is involved in a frontal collision with high energy.

[0070] like Figure 1 and Figure 3 As shown, crumple grooves 16 are provided at the second crumple position 14 and the third crumple position 15. The crumple grooves 16 are used to induce crumple of the front longitudinal beam 1 at the second crumple position 14 and the third crumple position 15. The crumple grooves 16 can be configured to be recessed towards the inside of the vehicle to ensure that the front longitudinal beam 1 can crumple inwards at the second crumple position 14 and the third crumple position 15. Furthermore, as... Figure 4 As shown, at least a portion of the front longitudinal beam 1 is configured to be bent at the first crumple position 13, and the rear side of the first crumple position 13 is bent inward relative to the front side of the first crumple position 13, so that the front longitudinal beam 1 can form an induced crumple structure protruding outward toward the outside of the vehicle at the first crumple position 13, and the induced crumple structure can be a protrusion or a step structure to ensure that the front longitudinal beam 1 can crumple outward at the first crumple position 13, thereby allowing the front longitudinal beam 1 to deform in a predetermined manner.

[0071] It should be noted that the rear side of the first crumple position 13 bends inward relative to the front side of the first crumple position 13, so that the rear side of the first crumple position 13 can form a certain angle with the longitudinal direction of the vehicle. The angle should not be too large or too small. If it is too large, it will result in the front longitudinal beam 1 occupying too much space along the transverse direction of the vehicle, which may cause the front longitudinal beam 1 to interfere with the engine. If it is too small, it will result in low reliability of crumple induction of the front longitudinal beam 1 at the first crumple position 13.

[0072] In some embodiments, the engine mount 12 is located between the second collapsible position 14 and the first collapsible position 13.

[0073] Specifically, the engine mounting bracket 12 is connected to the front bulkhead longitudinal beam 1 and is used to move outward under the action of at least part of the front bulkhead longitudinal beam 1 so that the elastic pad 122 can be separated from the engine cantilever 2, thereby allowing the engine cantilever 2 to fall downward together with the engine under the action of gravity, preventing the engine from intruding into the passenger compartment. Connecting the engine mounting bracket 12 between the second collapse position 14 and the first collapse position 13 can prevent the engine mounting bracket 12 from interfering with the first collapse position 13 or the second collapse position 14, so that the front bulkhead longitudinal beam 1 cannot deform in the predetermined manner at the first collapse position 13 or the second collapse position 14.

[0074] Furthermore, when the vehicle is subjected to a frontal collision, the second crumple position 14 crums inward and the first crumple position 13 crums outward. At this time, the engine mount 12 connected between the first crumple position 13 and the second crumple position 14 can move outward under the action of the first crumple position 13, thereby allowing the engine mount 12 to separate from the engine cantilever 2.

[0075] It should be noted that the engine mount 12 is spaced a distance from the first crumple position 13 and the second crumple position 14 along the longitudinal direction of the vehicle to ensure that the engine mount 12 does not interfere with the first crumple position 13 and the second crumple position 14. The distance between the front end of the engine mount 12 and the second crumple position 14 is about 50 mm, and the distance between the rear end of the engine mount 12 and the first crumple position 13 is about 50 mm, so as to ensure that the front longitudinal beam 1 can deform in a predetermined manner at the first crumple position 13 and the second crumple position 14 when subjected to a frontal collision.

[0076] This utility model also proposes a vehicle.

[0077] The vehicle according to the embodiments of the present invention includes a front bulkhead assembly 100 of any of the above embodiments. The front bulkhead assembly 100 includes a front longitudinal beam 1. When the vehicle is subjected to a frontal collision, the front longitudinal beam 1 can collapse inward at the second collapse position 14 and the third collapse position 15 and collapse outward at the first collapse position 13, so that at least a portion of the front longitudinal beam 1 can be bent and deformed in a W-shape to reliably absorb and dissipate the collision force. At the same time, the engine mount 12 is connected between the first collapse position 13 and the second collapse position 14, so that when the front longitudinal beam 1 undergoes bending deformation, the first collapse position 13 can drive the engine mount 12 to move outward. When the movement distance reaches a certain extent, the elastic rubber pad 122 in the engine mount 12 can separate from the engine cantilever 2, so that the engine cantilever 2 can fall downward together with the engine under the action of gravity, which can effectively prevent the engine from intruding into the passenger compartment and improve the vehicle's safety.
