[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.
[0027] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0028] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.
[0030] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0031] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0032] This application provides a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. For a vehicle, the front engine compartment serves as the point of impact in an accident, and the structural strength of the front engine compartment plays a crucial role in the extent of vehicle damage. More force transmission paths are needed within the front engine compartment to transfer force and protect the safety of the occupants.
[0033] Based on this, refer to Figures 1-4 This application provides a front engine compartment assembly.
[0034] The front of the vehicle indicates the direction of forward movement, and the rear indicates the direction of reverse movement. The left side of the vehicle is the driver's left-hand side when the driver is sitting in the driver's seat facing forward, and the right side is the driver's right-hand side when the driver is sitting in the driver's seat facing forward. The top of the vehicle is the direction from the ground to the roof, and the bottom of the vehicle is the direction from the roof to the ground.
[0035] The front engine compartment assembly includes two front longitudinal beams 10 and a front engine compartment frame 20. The two front longitudinal beams 10 are spaced apart along the left-right direction of the vehicle and extend along the front-rear direction of the vehicle. The two front longitudinal beams 10 are the left and right front longitudinal beams, respectively. The two front longitudinal beams 10 are located at the front of the vehicle, and energy-absorbing boxes are connected to the front of each front longitudinal beam 10. The front longitudinal beams 10 are one of the main load-bearing components of the vehicle body structure and provide mounting positions for the front bumper and radiator.
[0036] The front engine compartment frame 20 is located behind the two front longitudinal beams 10 and in front of the cockpit. The front engine compartment frame 20 includes a frame body 21 and two extension beams 22. The two extension beams 22 extend along the longitudinal direction of the vehicle. Both extension beams 22 are located in front of the frame body 21 and are spaced apart along the left and right direction of the vehicle. They are a left extension beam and a right extension beam, respectively. The left extension beam and the right extension beam are connected to the left and right ends of the frame body 21, respectively. The left front longitudinal beam is located in front of the left extension beam and is detachably connected to the left extension beam. The right front longitudinal beam is located in front of the right extension beam and is detachably connected to the right extension beam.
[0037] When the vehicle is hit, if the front engine compartment frame 20 or the front longitudinal beam 10 is deformed, it is easy to replace the front engine compartment frame 20 or the front longitudinal beam 10.
[0038] The forward engine compartment frame 20 is a single piece. Specifically, the forward engine compartment frame 20 is a single piece of cast aluminum. The forward engine compartment frame 20 can be manufactured by a single piece of cast aluminum, which avoids the creation of connection points between the forward engine compartment frame 20 and the extension beam 22, as well as weak points between the forward engine compartment frame 20 and the extension beam 22, thereby improving the structural strength of the forward engine compartment frame 20.
[0039] An extension beam 22 is provided at the front of the frame body 21 to connect the front longitudinal beam 10. This can prevent the front longitudinal beam 10 from being too long in the longitudinal direction of the vehicle and prevent the middle area of the front longitudinal beam 10 from being too weak. Moreover, the front engine compartment frame 20 is a single piece, which can ensure the structural strength of the front engine compartment frame 20 and thus increase the structural strength of the front of the vehicle.
[0040] When the vehicle is hit, the impact force on the front longitudinal beam 10 can be distributed to the front engine compartment frame 20 to disperse the force. At the same time, the front longitudinal beam 10 and the front engine compartment frame 20 have strong overall stability, which can reduce the degree of deformation of the front longitudinal beam 10 and the front engine compartment frame 20.
[0041] The front engine compartment assembly provided in this application embodiment includes a front engine compartment frame 20 comprising a frame body 21 and two extension beams 22. The extension beams 22 are connected to the rear of the front longitudinal beam 10. The front engine compartment frame 20 is a single piece, which can ensure the structural strength of the front engine compartment frame 20, thereby increasing the structural strength of the front of the vehicle and resulting in less damage to the vehicle body when the vehicle is involved in a collision.
[0042] Reference Figure 1 In one possible implementation of this application, the front engine compartment assembly further includes a first crossbeam 31, which extends along the left-right direction of the vehicle. The first crossbeam 31 connects the two front longitudinal beams 10 and is located above the front longitudinal beams 10. There is mounting space above the two front longitudinal beams 10 to facilitate the installation of the first crossbeam 31. The first crossbeam 31 can act as a bridge to increase the stability between the two front longitudinal beams 10.
[0043] When a vehicle is subjected to a frontal or side impact, the impact force can be transferred from the left or right front longitudinal beam to the first crossbeam 31, and then from the first crossbeam 31 to the right or left front longitudinal beam to disperse the force and reduce damage to the front of the vehicle; and the two front longitudinal beams 10 have strong stability and can also resist the impact force.
[0044] For example, the front longitudinal beam 10 is a square frame beam with a flat upper surface, which increases the connection area between the front longitudinal beam 10 and the first crossbeam 31. The first crossbeam 31 can be fixed to the front longitudinal beam 10 with bolts. The left and right ends of the first crossbeam 31 do not extend beyond the left and right outer sides of the front longitudinal beam 10, which can prevent the first crossbeam 31 from interfering with other components.
[0045] For example, the first crossbeam 31 is a square frame beam, and a cavity extending in the left and right direction of the vehicle is formed inside the first crossbeam 31, which can reduce the weight of the first crossbeam 31 and increase the structural strength of the first crossbeam 31.
[0046] Reference Figures 3-4 In one possible implementation of this application, the extension beam 22 has a cavity on the side facing the front longitudinal beam 10, and the front longitudinal beam 10 is inserted into the cavity to form an overlap 23 between the front longitudinal beam 10 and the extension beam 22. The extension beam 22 can fully wrap the connection of the front longitudinal beam 10 to increase the connection area between the front longitudinal beam 10 and the extension beam 22, thereby increasing the connection strength between the front longitudinal beam 10 and the extension beam 22.
[0047] For example, the front nacelle assembly also includes a protective plate 24, and the cavity of the extension beam 22 is provided with a notch in the outward direction to facilitate the installation of the front longitudinal beam 10 into the cavity. Then, the protective plate 24 is placed at the notch, and the protective plate 24 is fixedly connected to the extension beam 22 and the front longitudinal beam 10 with bolts.
[0048] Reference Figure 1 In one possible implementation of this application, the front engine compartment assembly further includes a second crossbeam 32, which is connected between two overlaps 23 to connect between the two front longitudinal beams 10 and the two extension beams 22. Bolts can be sequentially inserted through the second crossbeam 32, the front longitudinal beams 10 and the extension beams 22 to fix the second crossbeam 32.
[0049] The second crossbeam 32 can act as a bridge between the two front longitudinal beams 10 and between the two extension beams 22, thereby increasing the connection points between the front longitudinal beams 10 and the two extension beams 22 and increasing the overall strength of the front of the vehicle.
[0050] When a vehicle is subjected to a frontal or side impact, the impact force can be transferred from the left or right front longitudinal beam to the second crossbeam 32, and then from the second crossbeam 32 to the right or left front longitudinal beam. The impact force can also be transferred from the left or right extension beam to the second crossbeam 32, and then from the second crossbeam 32 to the right or left extension beam, in order to disperse the force and reduce the degree of impact on the front of the vehicle.
[0051] For example, both ends of the second crossbeam 32 extend beyond the left and right outer surfaces of the front longitudinal beam 10, which can prevent the second crossbeam 32 from interfering with other components.
[0052] For example, the second crossbeam 32 is a square frame beam, and a cavity extending in the left and right direction of the vehicle is formed inside the second crossbeam 32, which can reduce the weight of the second crossbeam 32 and increase the structural strength of the second crossbeam 32.
[0053] Reference Figure 1 In one possible implementation of this application, a third crossbeam 33 is further included. The third crossbeam 33 is connected between the two extension beams 22 and is positioned close to the frame body 21. The third crossbeam 33 is connected to the end of the two extension beams 22 near the frame body 21, thereby increasing the structural strength of the end of the two extension beams 22 near the frame body 21.
[0054] When a vehicle is subjected to a frontal or side impact, the impact force can be transferred from the left or right extension beam to the third crossbeam 33, and then from the third crossbeam 33 to the right or left extension beam, in order to disperse the force and reduce damage to the front of the vehicle.
[0055] For example, the extension beam 22 is a square frame beam with a flat upper surface, which increases the connection area between the extension beam 22 and the third crossbeam 33. The third crossbeam 33 can be fixed to the front longitudinal beam 10 with bolts. The left and right ends of the third crossbeam 33 extend beyond the left and right outer surfaces of the extension beam 22, which can prevent the third crossbeam 33 from interfering with other components.
[0056] For example, the third crossbeam 33 is a square frame beam, and a cavity extending in the left and right direction of the vehicle is formed inside the third crossbeam 33, which can reduce the weight of the third crossbeam 33 and increase the structural strength of the third crossbeam 33.
[0057] In a specific example, the first crossbeam 31, the second crossbeam 32, and the third crossbeam 33 are spaced apart along the front-rear direction of the vehicle and are arranged parallel to each other along the front-rear direction of the vehicle. When the vehicle is subjected to a frontal or side collision from the front, the impact force can be transmitted from the left or right front longitudinal beam to the first crossbeam 31, the second crossbeam 32, and the third crossbeam 33, and then transmitted through the first crossbeam 31, the second crossbeam 32, and the third crossbeam 33 to the right or left front longitudinal beam. The first crossbeam 31, the second crossbeam 32, and the third crossbeam 33 can all disperse the force to reduce damage to the front of the vehicle.
[0058] Reference Figures 1-2 In one possible implementation of this application, the front engine compartment assembly further includes two shock absorber towers 41, which are a left shock absorber tower and a right shock absorber tower, and are spaced apart along the left and right direction of the vehicle. Both shock absorber towers 41 are used to support and fix the shock absorbers.
[0059] Both shock absorber towers 41 are connected to the extension beam 22. The shock absorber towers 41 can be connected to the front engine compartment frame 20 to improve the overall structural strength of the front of the vehicle.
[0060] Both shock absorber towers 41 are located above the extension beam 22. Specifically, the left shock absorber tower is connected to the left extension beam and located above it; the right shock absorber tower is connected to the right extension beam and located above it. When the vehicle is subjected to a frontal or side impact, the impact force can be transferred from the front longitudinal beam 10 to the extension beam 22 and the shock absorber towers 41 to disperse the force and reduce damage to the front of the vehicle.
[0061] Reference Figures 1-2 In one possible implementation of this application, the shock absorber tower 41 includes a first region 411 and a second region 412. The first region 411 is located in front of the second region 412. The first region 411 is detachably connected to the front longitudinal beam 10, and the second region 412 is detachably connected to the extension beam 22. The shock absorber tower 41 is connected to both the front longitudinal beam 10 and the extension beam 22, and an interaction force can be formed among the shock absorber tower 41, the front longitudinal beam 10, and the extension beam 22 to improve the structural strength of the front of the vehicle.
[0062] When a vehicle is subjected to a frontal or side impact, the impact force can be distributed and transmitted among the front longitudinal beam 10, extension beam 22, and shock absorber tower 41, optimizing the transmission path to disperse the force and reduce damage to the front of the vehicle.
[0063] For example, bolts are used to fix the shock absorber tower 41 to the front longitudinal beam 10 and the extension beam 22.
[0064] Reference Figure 1In one possible implementation of this application, the front engine compartment assembly further includes a front strut bar 42, which is connected between two shock absorber towers 41. The front strut bar 42 is used to improve the overall rigidity of the front engine compartment and reduce the torsional deformation of the vehicle frame when the vehicle is cornering at high speed or driving aggressively.
[0065] Reference Figure 1 In one possible implementation of this application, the front engine compartment assembly further includes a front bulkhead 43, which is connected to the upper end of the front engine compartment frame 20 and also to the rear end of the front strut bar 42. The front bulkhead 43 is connected to both the front engine compartment frame 20 and the front strut bar 42, ensuring that the structural components of the front engine compartment assembly are interconnected. This increases the overall structural strength and stability of the front engine compartment assembly and helps to distribute forces during a collision.
[0066] In a specific example, two front longitudinal beams 10 extend in the front-rear direction and are connected to the front engine compartment frame 20. The first crossbeam 31, the second crossbeam 32, and the third crossbeam 33 extend in the left-right direction. The first crossbeam 31 connects between the two front longitudinal beams 10, the second crossbeam 32 connects between the two extension beams 22, and the third crossbeam 33 connects between the two extension beams 22. The front strut bar 42 connects between the two shock absorber towers 41. The front engine compartment assembly forms a two-longitudinal and four-transverse frame structure. In the event of an accident, the front engine compartment assembly structure is more stable, the transmission path is better, and the damage to the vehicle body is less.
[0067] When a vehicle is subjected to a frontal or side impact, the impact force can be transmitted from the front longitudinal beam 10 to the first crossbeam 31, the second crossbeam 32, and the third crossbeam 33. It can also be transmitted from the front longitudinal beam 10 to the front engine compartment frame 20, and to the shock absorber tower 41. From the shock absorber tower 41, it can be transmitted to the front strut bar 42. By dispersing the force through multiple pathways, the impact force is transmitted outward, ensuring the amount of intrusion into the cab and guaranteeing the safety of the occupants.

[0069] The vehicle provided in this application embodiment includes the front engine compartment assembly provided in any of the above-mentioned embodiments, and therefore has the same technical effect, that is, the front engine compartment assembly is in the form of a two-longitudinal and four-transverse frame, and the front engine compartment assembly structure is more stable, the transmission path is better, and the vehicle body damage is less in the event of a collision.
