Therefore, they should not be construed as limitations on this invention.

[0029] like Figures 1-2 As shown in the figure, a vehicle front compartment structure according to an embodiment of the present invention includes a front longitudinal beam 1. Two front longitudinal beams 1 are arranged opposite each other and both extend along the front-rear direction of the vehicle. The vehicle front compartment structure has two installation states. In one installation state, the vehicle front compartment structure is used to carry the engine. In the other installation state, the vehicle front compartment structure also includes a first crossbeam 2 and a second crossbeam 3. The first crossbeam 2 is connected between the two front longitudinal beams 1 near the front of the vehicle, and the second crossbeam 3 is connected between the two front longitudinal beams 1 near the rear of the vehicle. The vehicle front compartment structure is used to carry the drive motor.

[0030] Specifically, the front longitudinal beam 1 can be an elongated structure extending along the X direction, two front longitudinal beams 1 are arranged at intervals along the Y direction, the front longitudinal beam 1 is located in front of the front longitudinal beam 1, the two ends of the front longitudinal beam 4 are connected to the corresponding front longitudinal beam 1 through the energy absorption box, the first transverse beam 2 and the second transverse beam 3 are arranged along the Y direction, the two front longitudinal beams 1 are close to the front end of the vehicle, that is, the positive direction of the X axis, or close to the front end of the front longitudinal beam 4, the first transverse beam 2 can be connected between the two front longitudinal beams 1, the two front longitudinal beams 1 are close to the rear end of the vehicle, that is, the negative direction of the X axis, or the second transverse beam 3 can be connected between the two front longitudinal beams 1, the first transverse beam 2 and the second transverse beam 3 can be bolted, screwed or the like.

[0031] Air conditioning and cooling system components include compressors, air conditioning integrated modules, cooling integrated modules, and PTC heaters.

[0032] In this embodiment, the vehicle front compartment structure can be applied to vehicles with different driving forms such as extended range, hybrid and pure electric, that is, the vehicle front compartment structure can be used to install engines of extended range or hybrid driving assemblies, or can be used to install driving motors of pure electric driving assemblies. Specifically, in one of the installation states of the vehicle front compartment structure, such as extended range or hybrid form, the first transverse beam 2 and the second transverse beam 3 are not connected between the two front longitudinal beams 1, so that the engine of the extended range or hybrid power assembly is fixedly connected between the two front longitudinal beams 1, and the front longitudinal beam 1 is supported transversely (along the left and right directions of the vehicle) by the engine to avoid deformation and damage of the front longitudinal beam 1, that is, the vehicle front compartment structure in the case of small offset collision; in another installation state of the vehicle front compartment structure, such as pure electric driving form, the first transverse beam 2 is connected between the two front longitudinal beams 1 close to the front of the vehicle, and the second transverse beam 3 is connected between the two front longitudinal beams 1 close to the rear of the vehicle, and the two front longitudinal beams 1 are transversely supported by the two transverse beams (the first transverse beam 2 plays a major supporting role, and the second transverse beam 3 only serves as an auxiliary support) to avoid deformation and damage of the front longitudinal beam 1, that is, the vehicle front compartment structure in the case of small offset collision, thereby meeting the use requirements in the pure electric driving form; moreover, in the pure electric driving form, the pure electric driving motor occupies a smaller space, so that the air conditioning and cooling system components such as the compressor and the air conditioning integrated module in the front compartment structure can be arranged more concentratedly and fixedly installed on the second transverse beam 3, thereby optimizing the space arrangement and facilitating the installation of components.

[0033] It should be noted that in the pure electric driving form, two transverse beams (the first transverse beam 2 and the second transverse beam 3) are connected between the two front longitudinal beams 1, compared with connecting a single transverse beam between the two front longitudinal beams 1, the two transverse beams can ensure better transverse support force for the front longitudinal beam 1, effectively avoiding deformation and damage of the front longitudinal beam 1 in the case of small offset collision, and the second transverse beam 3 close to the rear end of the vehicle front compartment structure can be used to install the air conditioning and cooling system components such as the compressor and the air conditioning integrated module.

[0034] As Figure 2 shown, optionally, the first cross beam 2 and the second cross beam 3 are arranged in the front-rear direction of the vehicle.

[0035] Specifically, the first cross beam 2 and the second cross beam 3 are arranged in the front-rear direction of the vehicle, and the first cross beam 2 and the second cross beam 3 can be arranged relatively thin, i.e., the size in the X direction is relatively small, under the premise of meeting the requirements of stiffness and dynamic stiffness. Not only can the problem of deformation and damage of the front longitudinal beam 1 under the small offset collision of the pure electric drive form and the fixation of the air conditioning and cooling system parts be effectively solved, but also the volume of the first cross beam 2 and the second cross beam 3 is reduced, so that the weight of the first cross beam 2 and the second cross beam 3 is lighter, which is beneficial to the lightweight of the front compartment structure of the vehicle. In addition, the second cross beam 3 is arranged relatively rearward, and there is enough space in front of the second cross beam 3 to arrange the front compartment storage box. The front compartment storage box can be designed to be relatively large, so as to ensure the storage capacity.

[0036] Optionally, the first cross beam 2 and the second cross beam 3 are of an integrated structure.

[0037] Specifically, the size of the first cross beam 2 and the second cross beam 3 in the X direction is arranged to be relatively large, and the first cross beam 2 and the second cross beam 3 are connected as a whole, which is similar to a large tray, reducing the number of parts and simplifying the structure design.

[0038] As Figure 2 shown, optionally, the front longitudinal beam 1 is of a three-stage bending structure in the front-rear direction of the vehicle, the bending structure closest to the front of the vehicle in the three-stage bending structure is the first bending structure 11, and the bending structure closest to the rear of the vehicle in the three-stage bending structure is the third bending structure 13. The first bending structure 11 is connected with the first cross beam 2, and the third bending structure 13 is connected with the second cross beam 3. The front longitudinal beam 1 can be of a multi-stage bending structure in the front-rear direction, so as to ensure the stiffness and strength of the front longitudinal beam 1, so that the front longitudinal beam 1 can collapse and absorb energy along the preset direction, and the front longitudinal beam 1 is overall bent, so as to provide more uniform force transmission during the collision. When the multi-stage bending structure is a three-stage bending structure, the frontmost bending structure in the three-stage bending structure is the first bending structure 11, which can be connected with the first cross beam 2, and the last bending structure is the third bending structure 13, which can be connected with the second cross beam 3, so as to realize the connection of the first cross beam 2, the second cross beam 3 and the front longitudinal beam 1, and ensure the stress stability of the front longitudinal beam 1.

[0039] As Figure 2 shown, optionally, the two ends of the first cross beam 2 are respectively connected with the side walls of the two front longitudinal beams 1 facing each other, and the size of the first cross beam 2 in the up-down direction of the vehicle is smaller than the size of the front longitudinal beam 1 in the up-down direction of the vehicle.

[0040] And / or, the two ends of the second crossbeam 3 are respectively connected to the side walls of the two front longitudinal beams 1 facing each other, and the dimension of the second crossbeam 3 in the vertical direction of the vehicle is smaller than the dimension of the front longitudinal beam 1 in the vertical direction of the vehicle.

[0041] Specifically, the two ends of the first crossbeam 2 are respectively connected to the side walls of the two front longitudinal beams 1 facing each other, and the dimension of the first crossbeam 2 in the vertical direction of the vehicle is smaller than that of the front longitudinal beam 1 in the vertical direction of the vehicle, so that the first crossbeam 2 is located between the two front longitudinal beams 1 and does not exceed the upper surface of the front longitudinal beam 1. On the one hand, this reduces the space occupied by the first crossbeam 2 in the vertical direction of the vehicle and avoids the first crossbeam 2 interfering with the setting of other structures. On the other hand, it can also ensure the connection stability between the first crossbeam 2 and the front longitudinal beam 1.

[0042] The setting and function of the second crossbeam 3 are similar to those of the first crossbeam 2, and will not be repeated here.

[0043] like Figures 3-4 As shown, optionally, the first crossbeam 2 includes a first crossbeam body 21 and a first connecting bracket 22. The two first connecting brackets 22 are respectively disposed on one side of the two front longitudinal beams 1 facing each other. The two ends of the first crossbeam body 21 are respectively connected to the front longitudinal beam 1 through the corresponding first connecting bracket 22.

[0044] And / or, the second crossbeam 3 includes a second crossbeam body 31 and a second connecting bracket 32. The two second connecting brackets 32 are respectively disposed on one side of the two front longitudinal beams 1 facing each other. The two ends of the second crossbeam body 31 are respectively connected to the front longitudinal beam 1 through the corresponding second connecting brackets 32.

[0045] Specifically, the structures of the first connecting bracket 22 and the second connecting bracket 32 ​​may be different. The first connecting bracket 22 and the second connecting bracket 32 ​​can be fixed to the inner side wall of the front longitudinal beam 1 (i.e., the side wall of each front longitudinal beam 1 facing the other front longitudinal beam 1) by welding or bolting. The first connecting bracket 22 can be screwed to the first crossbeam body 21, and the second connecting bracket 32 ​​can be screwed to the second crossbeam body 31. The first crossbeam body 21 is connected to the front longitudinal beam 1 through the first connecting bracket 22, and the second crossbeam body 31 is connected to the front longitudinal beam 1 through the second connecting bracket 32. The connection is simple and convenient.

[0046] like Figure 3As shown, optionally, the first connecting bracket 22 comprises a support plate 221 and a connecting plate 222, the connecting plate 222 is vertically arranged and used to be connected with the front longitudinal beam 1, one end of the connecting plate 222 towards the lower side of the vehicle is connected with the support plate 221, the support plate 221 of each first connecting bracket 22 is located on one side of the connecting plate 222 towards another first connecting bracket 22, and the support plates 221 of two first connecting brackets 22 are used to commonly support the first beam body 21 and detachably connected with the first beam body 21.

[0047] Specifically, the first connecting bracket 22 can be integrally formed, the support plate 221 of the first connecting bracket 22 is horizontally arranged, and the connecting plate 222 is vertically arranged and can be welded with the front longitudinal beam 1 to improve the connection stability. The detachable connection between the first beam body 21 and the support plate 221 can be bolted or screwed, the first beam body 21 is placed on the support plates 221 of two first connecting brackets 22, and the bolt is used to pass through the first beam body 21 and the support plate 221 to realize the fixed connection between the first beam body 21 and the first connecting bracket 22, the support plate 221 has good support stability for the first beam body 21, which is beneficial to ensure the connection stability between the first connecting bracket 22 and the first beam body 21.

[0048] Since the two ends of the first beam body 21 are respectively detachably connected with the corresponding first connecting bracket 22, when the first beam 2 is installed, two first connecting brackets 22 can be fixedly installed on two front longitudinal beams 1 respectively, and then the first beam body 21 is bolted with the first connecting bracket 22, so that the first beam 2 can be conveniently and quickly installed.

[0049] As shown, Figure 3 Optionally, one end of the connecting plate 222 of each first connecting bracket 22 along the front-rear direction of the vehicle is bent towards one side of another first connecting bracket 22 to form a flange structure 2221, and the flange structure 2221 is in contact with one end surface of the first beam body 21 along the front-rear direction of the vehicle.

[0050] Specifically, one end of the connecting plate 222 of each first connecting bracket 22 is bent towards the side of the other first connecting bracket 22 along the vehicle front-rear direction to form a baffle structure 2221, that is, the connecting plate 222 is L-shaped. When the first cross beam body 21 is placed on the support plate 221, the two bent edges of the connecting plate 222 can be respectively attached to the adjacent two sides of the first cross beam body 21 to achieve positioning and assembly of the first cross beam body 21. For example, one end of the connecting plate 222 of each first connecting bracket 22 is bent towards the side of the other first connecting bracket 22 along the vehicle rear direction to form a baffle structure 2221, which can limit the rear movement of the first cross beam body 21 to achieve positioning and assembly in the front-rear direction.

[0051] As shown in Figure 4 Optionally, one end of the second connecting bracket 32 is detachably connected with the second cross beam body 31, and the other end of the second connecting bracket 32 is bent towards the vehicle up-down direction to be attached and connected with the front longitudinal beam 1 in parallel.

[0052] Specifically, the detachable connection between one end of the second connecting bracket 32 and the second cross beam body 31 can be bolted or screwed. The second connecting bracket 32 can be a bent bracket. One end of the second connecting bracket 32 is horizontally arranged and connected with the second cross beam body 31 by bolts. The other end of the second connecting bracket 32 is bent downwards and parallel to the inner side wall of the corresponding front longitudinal beam 1 to be attached and welded with the front longitudinal beam 1. The second connecting bracket 32 is a bent bracket, which has higher strength and facilitates the connection between the second cross beam body 31 and the front longitudinal beam 1.

[0053] Since the two ends of the second cross beam body 31 are respectively detachably connected with the corresponding second connecting bracket 32, when installing the second cross beam 3, the two second connecting brackets 32 can be first fixedly installed on the two front longitudinal beams 1, and then the second cross beam body 31 is bolted with the second connecting bracket 32, so that the second cross beam 3 can be conveniently and quickly installed.

[0054] As shown in Figure 4 Optionally, the second cross beam body 31 is provided with a connecting hole 311; and / or, the second cross beam body 31 is provided with a weight-reducing hole 312; and / or, at least one of the first cross beam body 21 and the second cross beam body 31 is a hollow beam.

[0055] Specifically, the connecting hole 311 can be a circular hole. The air conditioning and cooling system components, such as a cooling integrated module, are provided with a connecting column extending in the vertical direction. A rubber shock pad can be sleeved on the connecting column. The connecting column is inserted into the connecting hole 311 together with the rubber shock pad to achieve positioning and connection of the cooling integrated module on the second cross beam body 31. The connecting hole 311 can be spaced apart in the extension direction of the second cross beam body 31, that is, in the Y direction, to be respectively connected with the corresponding components.

[0056] The second cross beam body 31 is provided with a lightening hole 312, which can reduce the weight of the second cross beam body 31, and the lightening hole 312 can be arranged at a position corresponding to the compressor of the air cooling system, when the compressor is arranged on the second cross beam body 31, the compressor can block the lightening hole 312, so that the lightening hole 312 is not exposed outside, and the aesthetic appearance is affected. The first cross beam body 21 and the second cross beam body 31 are hollow beams, which can reduce the weight of the first cross beam body 21 and the second cross beam body 31, and are beneficial to realize the light weight of the vehicle front compartment structure.

[0057] The utility model discloses still one embodiment proposes a vehicle, including above-mentioned vehicle front compartment structure. The vehicle of this embodiment has the same advantage as the vehicle front compartment structure of prior art, and will not be repeated.

[0058] Specifically, the front compartment structure of the vehicle can be compatible with different power forms, that is, the power assembly of extended range, hybrid and pure electric can share the front compartment structure. At the same time, when cooperating with various power forms, the front compartment structure of the vehicle can avoid deformation and extrusion damage of the front longitudinal beam, that is, the front compartment structure, when small offset collision occurs.

[0059] Although the utility model discloses as above, the protection scope of the utility model is not only limited to this. The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall into the protection scope of the utility model.
