[0087] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0088] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0089] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0090] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0091] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0092] The front of the new energy vehicle is provided with a radiator 5, which uses the airflow generated when the vehicle is running or the forced convection of the fan to take away the heat in the coolant, so that the coolant is cooled and then circulated back to the position where heat absorption is required, thereby achieving the cooling effect. In the prior art, the front cabin structure of the hybrid vehicle is provided with an engine, so the space of the front cabin of the hybrid vehicle is larger, and the front cabin structure of the pure electric vehicle is not provided with an engine, so the space of the front cabin of the pure electric vehicle is smaller. Since the size of the front cabin space of the hybrid vehicle and the pure electric vehicle is different, the radiator 5 is installed at the front end of the front cabin space. The difference in the front cabin space will result in different radiator installation positions and angles. Therefore, the front cabin structures of vehicles of different power types need to be designed separately, resulting in poor versatility of the front cabin structures in vehicles of different power types.

[0093] like Figures 1 to 4 As shown, an embodiment of the present application provides a front cabin structure, which includes a column 1, an upper curved beam 2 and a lower curved beam 3. The column 1 is arranged at the front end of the beam of the front cabin structure, and the upper curved beam 2 and the lower curved beam 3 are respectively installed at the upper end and the lower end of the column 1. The front cabin structure also includes a radiator 5, which is located between the upper curved beam 2 and the lower curved beam 3. The column 1 includes a main body 11 and an extension 12, and the extension 12 is detachably installed on the main body 11 to adjust the length of the column 1. When the extension 12 is installed on the main body 11, the extension 12 is located at the upper end of the main body 11, the upper curved beam 2 is detachably installed on the extension 12, and the lower curved beam 3 is installed at the lower end of the main body 11. When the extension 12 is removed, the upper curved beam 2 is detachably installed on the upper end of the main body 11, and the lower curved beam 3 is installed on the lower end of the main body 11. The upper curved beam 2 is used to support the hood 4. When the extension portion 12 is removed, the upper curved beam 2 is directly installed on the upper end of the main body 11, so that the height of the upper curved beam 2 is reduced, and then the height of the front end of the hood 4 is reduced.

[0094] The front cabin structure has a front cabin space, an extension portion 12 is installed on the main body 11, and the upper curved beam 2 is installed on the extension portion 12, which increases the distance between the upper curved beam 2 and the lower curved beam 3, thereby increasing the front cabin space, so that the engine of the hybrid vehicle can be placed in the front cabin space, making the front cabin structure suitable for hybrid vehicles. The extension portion 12 is removed, and the upper curved beam 2 is installed on the upper end of the main body 11, which reduces the height of the upper curved beam 2, reduces the distance between the upper curved beam 2 and the lower curved beam 3, reduces the space of the front cabin, and makes the front cabin structure suitable for pure electric vehicles. At the same time, the front end of the hood 4 is set above the upper curved beam 2, and the height of the upper curved beam 2 is reduced, which reduces the height of the front end of the hood 4, thereby reducing the wind resistance of the pure electric vehicle.

[0095] By installing the extension portion 12 on the main body 81 of the pillar 1, the front cabin structure can meet the needs of hybrid vehicles, allowing the engine to be placed in the front cabin space, and can also meet the low wind resistance requirements of pure electric vehicles. While ensuring the performance of the front cabin structure, the compatibility of the front cabin structure is improved.

[0096] like Figure 1 and Figure 2 As shown, in a possible embodiment, when the extension portion 12 is installed on the main body 11, the upper curved beam 2 is installed on the extension portion 12, and the space between the upper curved beam 2 and the lower curved beam 3 is larger, and the radiator 5 can be vertically installed between the upper curved beam 2 and the lower curved beam 3; when the extension portion 12 is removed, the upper curved beam 2 is installed on the main body 11, the height of the upper curved beam 2 is reduced, and the space between the upper curved beam 2 and the lower curved beam 3 is smaller, and the radiator 5 can be obliquely arranged between the upper curved beam 2 and the lower curved beam 3.

[0097] The radiator 5 is installed vertically, which reduces the space occupied by the radiator 5 in the front cabin space, so that the front cabin space has enough space to accommodate the engine, making the front cabin structure suitable for hybrid vehicles; in pure electric vehicles, there is no need to set the engine in the front cabin space, so there is a larger space to accommodate the radiator 5, so that the radiator 5 can be set obliquely, reducing the vertical size of the radiator 5 after installation, so that the upper curved beam 2 can be moved downward to reduce the height of the front end of the hood 4, thereby reducing the wind resistance of the pure electric vehicle.

[0098] like Figures 5 to 10 As shown, in a possible embodiment, the upper curved beam 2 and the lower curved beam 3 are provided with a plurality of snap-in holes on their opposite sides, and the upper and lower sides of the radiator 5 are provided with a plurality of snap-in parts 51. When the extension part 12 is installed on the main body 11, the snap-in parts 51 on the upper side of the radiator 5 are snap-fitted with the snap-in holes on the upper curved beam 2, and the snap-in parts 51 on the lower side of the radiator 5 are snap-fitted with the snap-in holes on the lower curved beam 3.

[0099] The extension part 12 is installed on the main body 11, increasing the distance between the upper curved beam 2 and the lower curved beam 3, so that the radiator 5 can be arranged vertically, and the upper and lower sides are respectively installed on the upper curved beam 2 and the lower curved beam 3, thereby reducing the space occupied by the radiator 5 in the front cabin space, making it easy to place the engine in the front cabin space, and also enabling the vibration generated by the radiator 5 to be transmitted to the vehicle body through the upper curved beam 2 and the lower curved beam 3, which is beneficial to improving the NVH performance of the vehicle. The radiator 5 is connected to the upper curved beam 2 and the lower curved beam 3 through the clamping piece 51 and the clamping hole, which reduces the difficulty of installing the radiator 5 and is beneficial to improving the assembly efficiency of the front cabin structure.

[0100] The lower curved beam 3 can be connected to the main body 11 of the column 1 by screws or welding, and the upper curved beam 2 and the extension 12 of the column 1 are detachably connected by bolts. After the front cabin structure is painted, the upper curved beam 2 can be removed first, and then the lower side of the radiator 5 can be clamped to the lower curved beam 3, and then the upper curved beam 2 can be clamped to the upper side of the radiator 5, and finally the upper curved beam 2 can be installed on the extension 12 of the column 1 by bolts to facilitate the installation of the radiator 5.

[0101] like Figure 5 , Figure 6 and Fig. 9 As shown, in a possible embodiment, the clamping hole 21 is a stepped hole, the side wall of the clamping hole 21 extends in a direction away from the radiator 5, and the clamping member 51 abuts against the end of the side wall of the clamping hole after passing through the clamping hole 21. Along the direction away from the radiator 5, the diameter of the clamping hole 21 gradually decreases.

[0102] The upper curved beam 2 and the lower curved beam 3 are both provided with a clamping hole 21. The step hole can increase the strength of the upper curved beam 2 and the lower curved beam 3 and reduce the possibility of deformation at the position where the clamping hole 21 is provided. The diameter of the clamping hole 21 is gradually reduced, so that the side wall of the clamping hole 21 forms an inclined surface, which facilitates the clamping member 51 to extend into the clamping hole, thereby reducing the difficulty of installing the radiator 5.

[0103] like Figure 7 and Fig.10 As shown, in a possible embodiment, the clamping member 51 includes an abutting portion 511 and a clamping portion 512. When the radiator 5 is mounted on the upper curved beam 2 and / or the lower curved beam 3, the clamping portion 512 passes through the clamping hole 21. The side wall of the clamping hole 21 is located between the abutting portion 511 and the clamping portion 512. The abutting portion 511 abuts against the upper curved beam 2 or the lower curved beam 3, and the clamping portion 512 abuts against the side wall of the clamping hole 21. In the direction away from the abutting portion 511, the cross-sectional area of ​​the clamping portion 512 gradually decreases, so that the outer surface of the clamping portion 512 forms a guide surface, which facilitates the clamping portion 512 to pass through the clamping hole 21.

[0104] The cross-sectional area of ​​the abutting portion 511 and the cross-sectional area of ​​the side of the clamping portion 512 close to the abutting portion 511 are both larger than the cross-sectional area of ​​the clamping hole 21. After the clamping portion 512 passes through the clamping hole 21, it can be clamped with the upper curved beam 2 or the lower curved beam 3 to radially limit the relative position of the radiator 5 and the upper curved beam 2 or the lower curved beam 3. The cross-sectional area of ​​the side of the clamping portion 512 away from the abutting portion 511 is smaller than the cross-sectional area of ​​the clamping hole 21, and the clamping component 51 is a rubber component that can undergo slight deformation to facilitate the clamping portion 512 to pass through the clamping hole 21.

[0105] like Figure 7 and Fig.10 As shown, in a possible embodiment, the clamping members 51 on the upper and lower sides of the radiator 5 are respectively clamped with the upper curved beam 2 and the lower curved beam 3 to limit the relative position of the radiator 5 and the upper curved beam 2 and the lower curved beam 3. The size of the clamping member 51 clamped with the lower curved beam 3 is larger than the size of the clamping member 51 clamped with the upper curved beam 2, so that the clamping member 51 clamped with the lower curved beam 3 can bear the weight of the radiator 5, thereby improving the reliability of the radiator 5 after installation.

[0106] like Fig.11 and Fig.14 As shown, in a possible embodiment, a fixing component 31 is provided on the lower curved beam 3. When the radiator 5 is fixed obliquely, the two ends of the radiator 5 cannot be connected to the upper curved beam 2 and the lower curved beam 3. A mounting bracket 9 is provided in the front cabin structure, one end of the radiator 5 is connected to the fixing component 31, and the other end is overlapped with the mounting bracket 9.

[0107] In a pure electric vehicle, electronic devices need to be installed in the front cabin, and a mounting bracket 9 is provided in the front cabin structure, so that the electronic devices can be installed in the front cabin through the mounting bracket 9. The lower end of the radiator 5 is connected to the lower curved beam 3, and the upper end is connected to the mounting bracket 9, so that the radiator 5 is fixed obliquely in the front cabin space, reducing the height of the front cabin, thereby reducing the height of the front end of the hood 4, which is beneficial to reducing the wind resistance of the pure electric vehicle.

[0108] like Fig.12 and Fig.13 As shown, in a possible embodiment, the fixing assembly 31 includes a base 311 fixed to the lower curved beam 3, a limiting pin 313 is provided on the base 311, and a limiting ring 312 is fixed to the base 311 through the limiting pin 313. The limiting ring 312 includes a first limiting groove 312a, and an opening 53 is provided at the lower end of the radiator 5. The position where the first limiting groove 312a is provided in the limiting ring 312 is located in the opening 53, and the side wall of the opening 53 is located in the first limiting groove 312a, so that the lower end of the radiator 5 is engaged with the limiting ring 312, so as to fix the lower end of the radiator 5 to the lower curved beam 3.

[0109] When the radiator 5 is set obliquely, the lower end of the radiator 5 is connected to the lower curved beam 3 through the fixing assembly 31, one end of the base 311 in the fixing assembly 31 can be fixed to the lower curved beam 3 and the main body 11 by welding, and the other end is used to install the limit ring 312. The angle between the two ends of the base 311 can be set according to the inclination degree of the radiator 5, so that the radiator 5 can be set obliquely. The side wall of the opening 53 at the lower end of the radiator 5 extends into the first limit groove 312a in the limit ring 312, which can limit the relative position of the radiator 5 and the limit ring 312 along the axial direction of the limit ring 312 to improve the stability of the radiator 5.

[0110] like Fig.14 and Fig.15 As shown, in a possible embodiment, a protrusion 52 is provided at the upper end of the radiator 5, and the protrusion 52 overlaps the mounting bracket 9. A fixing member 91 is provided on the mounting bracket 9, and both ends of the fixing member 91 are connected to the mounting bracket 9. The protrusion 52 is located between the mounting bracket 9 and the fixing member 91 to limit the relative position of the radiator 5 and the mounting bracket 9.

[0111] The fixing member 91 may be a "J"-shaped structure, and two legs 911 of the fixing member 91 are fixed to the mounting bracket 9 by screws, so as to fix the fixing member 91 to the mounting bracket 9. The middle position of the fixing member 91 protrudes upward, and a receiving space is formed between the fixing member 9 and the mounting bracket 9. After the protrusion 52 extends into the receiving space, the relative position of the protrusion 52 and the mounting bracket 9 can be limited in the vertical direction.

[0112] like Fig.14 and Fig.15As shown, in a possible embodiment, the protrusion 52 includes a second limiting groove 521, and the second limiting groove 521 is located on the side of the protrusion away from the mounting bracket 9. After the protrusion extends between the fixing member 91 and the mounting bracket 9, the fixing member 91 is located in the second limiting groove 521.

[0113] The two side walls of the second limiting groove 521 abut against the two sides of the fixing member 91 , and can limit the relative position between the protrusion 52 and the fixing member 91 along the length direction of the front compartment structure, so as to improve the stability of the radiator 5 .

[0114] like Fig.14 and Fig.15 As shown, in a possible embodiment, a guide surface 522 is provided at the end of the protrusion 52, and the guide surface 522 is located on the side of the protrusion 52 away from the mounting bracket 9. Along the direction away from the second limiting groove 521, the guide surface 522 is inclined toward the direction close to the mounting bracket 9.
