TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle body structure, and in particular to a front compartment structure and a vehicle. BACKGROUND

[0002] The head of a new energy vehicle is provided with a radiator. The radiator uses the airflow generated when the vehicle is running or the forced convection of a fan to take away the heat in the cooling liquid, so that the cooling liquid is cooled and then recycled to the position that needs to absorb heat, thereby achieving the effect of cooling. The radiator is provided with a mounting bracket, and the radiator is mounted at the front end of the front compartment.

[0087] For better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0088] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall 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 the plural forms, unless the context clearly indicates otherwise.

[0090] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0091] It should be noted that the "up", "down", "left", "right" and other directional words described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "under", it can be directly connected to another element "on" or "under" or indirectly connected to another element "on" or "under" through an intermediate element.

[0092] The front of the new energy vehicle is provided with a radiator 5, which uses the airflow generated during vehicle driving or forced convection of the fan to take away the heat in the cooling liquid, so that the cooling liquid is cooled and then recycled to the position needing heat absorption, thereby achieving the effect of cooling. In the prior art, the engine is arranged in the front compartment structure of the hybrid vehicle, so the space of the front compartment of the hybrid vehicle is relatively large, and the engine is not arranged in the front compartment structure of the pure electric vehicle, so the space of the front compartment of the pure electric vehicle is relatively small. Since the sizes of the front compartments of the hybrid vehicle and the pure electric vehicle are different, the radiator 5 is installed at the front end of the front compartment space, and the different sizes of the front compartments will result in different installation positions and angles of the radiator, so the front compartment structures of vehicles of different power types need to be designed separately, resulting in poor universality of the front compartment structures of vehicles of different power types.

[0093] As shown in Figures 1 to 4 , the embodiment of the present application provides a front compartment structure, the front compartment structure comprises a stand column 1, an upper bent beam 2 and a lower bent beam 3, the stand column 1 is arranged at the front end of the girder of the front compartment structure, and the upper bent beam 2 and the lower bent beam 3 are respectively arranged at the upper end and the lower end of the stand column 1. The front compartment structure further comprises a radiator 5, and the radiator 5 is located between the upper bent beam 2 and the lower bent beam 3. The stand column 1 comprises a main body part 11 and an extension part 12, and the extension part 12 is detachably arranged on the main body part 11 to adjust the length of the stand column 1. When the extension part 12 is arranged on the main body part 11, the extension part 12 is located at the upper end of the main body part 11, the upper bent beam 2 is detachably arranged on the extension part 12, and the lower bent beam 3 is arranged at the lower end of the main body part 11. When the extension part 12 is removed, the upper bent beam 2 is detachably arranged at the upper end of the main body part 11, and the lower bent beam 3 is arranged at the lower end of the main body part 11. The upper bent beam 2 is used for supporting an engine cover 4, and when the extension part 12 is removed, the upper bent beam 2 is directly arranged at the upper end of the main body part 11, so that the height of the upper bent beam 2 is reduced, and then the height of the front end of the engine cover 4 is reduced.

[0094] The front compartment structure has a front compartment space, the extension part 12 is arranged on the main body part 11, and the upper bent beam 2 is arranged on the extension part 12, so that the distance between the upper bent beam 2 and the lower bent beam 3 is increased, and then the front compartment space is increased, so that the engine of the hybrid vehicle type can be placed in the front compartment space, and the front compartment structure is suitable for the hybrid vehicle type. When the extension part 12 is removed, the upper bent beam 2 is arranged at the upper end of the main body part 11, so that the height of the upper bent beam 2 is reduced, the distance between the upper bent beam 2 and the lower bent beam 3 is reduced, the front compartment space is reduced, and the front compartment structure is suitable for the pure electric vehicle type. At the same time, the front end of the engine cover 4 is arranged above the upper bent beam 2, the height of the upper bent beam 2 is reduced, the height of the front end of the engine cover 4 is reduced, and then the wind resistance of the pure electric vehicle type is reduced.

[0095] By arranging the extension part 12 on the main body part 81 of the stand column 1 or not, the front compartment structure can meet the requirements of the hybrid vehicle type and the low wind resistance of the pure electric vehicle type, and the compatibility of the front compartment structure is improved under the condition of ensuring the performance of the front compartment structure.

[0096] As shown in Figure 1 and Figure 2 , in a possible embodiment, when the extension part 12 is arranged on the main body part 11, the upper bent beam 2 is arranged on the extension part 12, the space between the upper bent beam 2 and the lower bent beam 3 is large, and the radiator 5 can be vertically arranged between the upper bent beam 2 and the lower bent beam 3. When the extension part 12 is removed, the upper bent beam 2 is arranged on the main body part 11, the height of the upper bent beam 2 is reduced, the space between the upper bent beam 2 and the lower bent beam 3 is small, and the radiator 5 can be arranged between the upper bent beam 2 and the lower bent beam 3.

[0097] The radiator 5 is vertically installed, which reduces the size of the space occupied by the radiator 5 in the front compartment space, so that the front compartment space has enough space to accommodate the engine, and the front compartment structure is suitable for hybrid models; in a pure electric power model, the front compartment space does not need to be provided with an engine, so it has a larger space to accommodate the radiator 5, so that the radiator 5 can be arranged obliquely, which reduces the vertical size of the radiator 5 after installation, so that the upper bending beam 2 can be moved downward to reduce the height of the front end of the engine cover 4, thereby reducing the wind resistance of the pure electric power model.

[0098] As shown in Figures 5 to 10 , in a possible embodiment, the opposite sides of the upper bending beam 2 and the lower bending beam 3 are provided with a plurality of clamping holes, and the upper and lower sides of the radiator 5 are provided with a plurality of clamping pieces 51. When the extension part 12 is installed on the main body part 11, the clamping piece 51 on the upper side of the radiator 5 is clamped with the clamping hole on the upper bending beam 2, and the clamping piece 51 on the lower side of the radiator 5 is clamped with the clamping hole on the lower bending beam 3.

[0099] The extension part 12 is installed on the main body part 11, which increases the distance between the upper bending beam 2 and the lower bending beam 3, so that the radiator 5 can be vertically arranged and installed on the upper bending beam 2 and the lower bending beam 3, thereby reducing the space occupied by the radiator 5 in the front compartment space, facilitating the placement of the engine in the front compartment space, and also enabling the vibration generated by the radiator 5 to be transmitted to the vehicle body through the upper bending beam 2 and the lower bending beam 3, which is beneficial to improve the NVH performance of the vehicle. The radiator 5 is clamped with the upper bending beam 2 and the lower bending beam 3 through the clamping piece 51 and the clamping hole, which reduces the installation difficulty of the radiator 5, and is beneficial to improve the assembly efficiency of the front compartment structure.

[0100] The lower bending beam 3 and the main body part 11 of the pillar 1 can be connected by screws or welding, and the upper bending beam 2 and the extension part 12 of the pillar 1 are detachably connected by bolts. After the front compartment structure is painted, the upper bending beam 2 can be removed first, then the lower side of the radiator 5 is clamped on the lower bending beam 3, then the upper side of the radiator 5 is clamped with the upper bending beam 2, and finally the upper bending beam 2 is installed on the extension part 12 of the pillar 1 by bolts, which facilitates the installation of the radiator 5.

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

[0102] The upper bent beam 2 and the lower bent beam 3 are provided with clamping holes 21, the stepped holes can increase the strength of the upper bent beam 2 and the lower bent beam 3, and reduce the possibility of deformation at the position provided with the clamping holes 21. The diameter of the clamping holes 21 gradually decreases, the side wall of the clamping hole 21 forms an inclined surface, the clamping piece 51 is convenient to extend into the clamping hole, and the installation difficulty of the radiator 5 is reduced.

[0103] As shown in Figure 7 and Figure 10 , in a possible embodiment, the clamping piece 51 includes an abutting portion 511 and a clamping portion 512, when the radiator 5 is installed on the upper bent beam 2 and / or the lower bent 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 bent beam 2 or the lower bent 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, the outer surface of the clamping portion 512 forms a guide surface, and the clamping portion 512 is convenient 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 greater than the cross-sectional area of the clamping hole 21, after the clamping portion 512 passes through the clamping hole 21, the clamping portion 512 can be clamped with the upper bent beam 2 or the lower bent beam 3, so as to limit the relative position of the radiator 5 and the upper bent beam 2 or the lower bent beam 3 in the radial direction, the cross-sectional area of the side of the clamping portion 512 away from the abutting portion 511 is less than the cross-sectional area of the clamping hole 21, and the clamping piece 51 is a rubber piece, which can be slightly deformed, so as to facilitate the clamping portion 512 to pass through the clamping hole 21.

[0105] As shown in Figure 7 and Figure 10 , in a possible embodiment, the clamping pieces 51 on the upper and lower sides of the radiator 5 are respectively clamped with the upper bent beam 2 and the lower bent beam 3, so as to limit the relative position of the radiator 5, the upper bent beam 2 and the lower bent beam 3. The size of the clamping piece 51 clamped with the lower bent beam 3 is greater than the size of the clamping piece 51 clamped with the upper bent beam 2, so that the clamping piece 51 clamped with the lower bent beam 3 can bear the weight of the radiator 5, and the reliability of the radiator 5 after installation is improved.

[0106] As shown in Figure 11 and Figure 14 , in a possible embodiment, the lower bent beam 3 is provided with a fixing assembly 31, when the radiator 5 is fixed obliquely, the two ends of the radiator 5 cannot be connected with the upper bent beam 2 and the lower bent beam 3, the front cabin structure is provided with a mounting bracket 9, one end of the radiator 5 is connected with the fixing assembly 31, and the other end is overlapped with the mounting bracket 9.

[0107] In pure electric vehicles, electronic components need to be installed in the front compartment. A mounting bracket 9 is provided in the front compartment structure to allow these components to be installed. 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, allowing the radiator 5 to be fixed obliquely in the front compartment space. This reduces the height of the front compartment, and consequently lowers the height of the front end of the hood 4, which helps reduce the wind resistance of the pure electric vehicle.

[0108] like Figure 12 and Figure 13 As shown, in one possible embodiment, the fixing component 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 by the limiting pin 313. The limiting ring 312 includes a first limiting groove 312a. The lower end of the heat sink 5 is provided with an opening 53. The position of the first limiting groove 312a in the limiting ring 312 is located within the opening 53, and the sidewall of the opening 53 is located within the first limiting groove 312a, so that the lower end of the heat sink 5 is engaged with the limiting ring 312 to fix the lower end of the heat sink 5 to the lower curved beam 3.

[0109] When the radiator 5 is installed at an angle, its lower end is connected to the lower curved beam 3 via a fixing assembly 31. One end of the base 311 in the fixing assembly 31 can be welded to the lower curved beam 3 and the main body 11, while the other end is used to install the limiting ring 312. The included angle between the two ends of the base 311 can be set according to the inclination of the radiator 5, allowing the radiator 5 to be installed at an angle. The sidewall of the opening 53 at the lower end of the radiator 5 extends into the first limiting groove 312a in the limiting ring 312, which can restrict the relative position of the radiator 5 and the limiting ring 312 along the axial direction of the limiting ring 312, thereby improving the stability of the radiator 5.

[0110] like Figure 14 and Figure 15 As shown, in one possible embodiment, the upper end of the heat sink 5 is provided with a protrusion 52, which overlaps with the mounting bracket 9. The mounting bracket 9 is provided with a fixing member 91, the two ends of which 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 heat sink 5 and the mounting bracket 9.

[0111] The fastener 91 can be a "U" shaped structure. The two legs 911 of the fastener 91 are fixed to the mounting bracket 9 by screws to fix the fastener 91 to the mounting bracket 9. The middle position of the fastener 91 protrudes upward, forming a receiving space with the mounting bracket 9. After the protrusion 52 extends into the receiving space, it can limit the relative position of the protrusion 52 and the mounting bracket 9 in the vertical direction.

[0112] like Figure 14 and Figure 15As shown, in one possible embodiment, the protrusion 52 includes a second limiting groove 521, which 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, which 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 Figure 14 and Figure 15 As shown, in one possible embodiment, the end of the protrusion 52 is provided with a guide surface 522. 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 towards the mounting bracket 9.
