[0034] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] An embodiment of the present invention provides a device for fixing a front end frame. Figures 1 to 3As shown, the device for fixing the front end frame includes a first connecting member 110, a second connecting member 120 and a third connecting member 130. The first connecting member 110 is used to connect the lower cross beam 210 of the front end frame 200 to the front bumper beam 310 and the subframe 320. The second connecting member 120 is used to be arranged between the lower cross beam 210 of the front end frame 200 and the upper cross beam 220 of the front end frame 200 to connect the front end frame 200 to the front bumper beam 310 and the vehicle body end plate 330. The third connecting member 130 is used to connect the upper cross beam 220 of the front end frame 200 to the upper longitudinal beam 340 of the vehicle body. Therefore, in the vertical direction, the upper, middle and lower parts of the front end frame 200 can be connected and fixed to the vehicle body to form a three-layer fixed structure, which improves the rigidity of the fixation of the front end frame 200, thereby improving the supporting effect of the front end frame 200, and can effectively prevent the front end module 200 from sinking, and prevent the front end frame 200 and functional components such as the lower fixing mechanism of the cooling device from failing, thereby avoiding abnormal noise and loss of function of the vehicle.

[0036] In one embodiment, Figure 4 and 5 As shown, the first connecting member 110 includes a first connecting portion 111, a second connecting portion 112 and a main body 113. The first connecting portion 111 is used to connect to the lower cross beam 210 of the front end frame 200. The second connecting portion 112 is used to connect to the front anti-collision beam 310 or the subframe 320. The main body 113 is arranged between the first connecting portion 111 and the second connecting portion 112, and mainly plays a connecting role. A mounting plane 114 for overlapping is formed on the first connecting portion 111 and the second connecting portion 112. The first connecting member 110 of this arrangement has a simple structure and strong adaptability, and can achieve the purpose of effective connection and fixation.

[0037] Preferably, the first connecting member 110 is constructed as a plate-like member. And a bending rib 115 is provided in the longitudinal direction of the plate-like member. For example, the bending rib 115 can be provided at both ends of the plate-like member, extending along the extension direction of the plate-like member, so as to make the cross-section of the first connecting member 110 U-shaped, or the bending rib 115 is provided at one end of the plate-like member, so as to make the cross-section of the first connecting member 110 angular. The above-mentioned arrangement can improve the strength and rigidity of the first connecting member 110, increase the ability to resist deformation under stress, and improve the connection stability. Of course, other reinforcement structures can also be provided on the plate-like member as needed, for example, a reinforcement groove-like structure is provided on the plate-like member.

[0038] A positioning tongue 116 is protrudingly provided on the first connecting portion 111 or the second connecting portion 112. The positioning tongue 116 is used to play a positioning role and facilitate installation. For example, during use, a positioning hole 311 is correspondingly provided on the front anti-collision beam 310. During installation, the positioning tongue 116 is inserted into the positioning hole 311, the two are matched, and the first connecting member 110 is hung on the front anti-collision beam 310. At this time, the first connecting portion 111 and the second connecting portion 112 have both reached the installation position, and the operator does not need to limit the first connecting member 110 by hand. It can be seen that by providing the positioning tongue 116, the installation can be simplified and the complexity of the operation can be reduced. It can be understood that due to the different components connected to the first connecting member 110, the setting object and position of the positioning hole can be adjusted accordingly.

[0039] A through hole 117 for bolt connection is provided on the first connecting portion 111 and the second connecting portion 112. The through hole 117 passes through the mounting plane 114. In other words, the first connecting member 110 is connected to other components by bolts, and the structure is simple and easy to implement. Of course, the first connecting member 110 can also be connected to other components by other methods such as welding.

[0040] Four of the first connecting members 110 are arranged on the front frame 200 to form a square structure. That is, the first connecting members 110 are at least four, for example, four. Specifically, two of the four first connecting members 110 are arranged on the front frame 200 at intervals to connect to the front anti-collision beam 310, such as Figure 4 The other two first connecting members 110 of the four are arranged at intervals on the front frame 200, and the other ends are connected to the sub-frame 320, as shown. Figure 5 As shown. For example, a pair of first connectors 110 are symmetrical with respect to the longitudinal center line of the vehicle body. Through the four-corner connection structure of the first connector 110, the front frame 200, the front anti-collision beam 310 and the subframe 320 can be rigidly connected at the lower end of the front frame 200, thereby improving the support capacity of the front frame 200, and in particular, effectively ensuring the effective connection between the front frame 200 and the cooling device, avoiding connection failure, and improving the ability of the front module to avoid sinking.

[0041] The installation of a first connecting member 110 is taken as an example to explain the installation of the first connecting member 110 in detail. Specifically, first, the positioning tongue 116 is inserted into the positioning hole 311. Through the cooperation between the positioning tongue 116 and the positioning hole 311, the first connecting portion 111 is pre-positioned to the installation position. At this time, the installation plane 114 at the first connecting portion 111 is located on the upper wall surface of the lower cross beam 210 of the front end frame 200. The installation plane 114 at the second connecting portion 112 is planarly abutted against the rear wall surface of the front bumper beam 310. Afterwards, the first connecting portion 111 is fixed to the front end frame 200 by bolts, and the second connecting portion 112 is fixed to the front bumper beam 310. The above connection and installation realizes the fixation of the front end frame 200 and the vehicle body. The setting method of other first connecting members 110 is the same or similar to the above connection, which can be foreseen by those skilled in the art and will not be repeated here.

[0042] In one embodiment, the second connecting member 120 includes a mounting plate 121 for fixing to the front frame 200, a first connecting member 122 disposed between the mounting plate 121 and the front anti-collision beam 310, and a second connecting member 123 disposed between the mounting plate 121 and the vehicle body end plate 330. More specifically, the mounting plate 121 is a plate-shaped member extending between the lower cross beam 210 and the upper cross beam 220 of the front frame 200. According to actual needs, the first connecting member 122 and the second connecting member 123 can be set as a plate member, a beam member, a shell member or a frame-shaped member.

[0043] In one embodiment, the third connecting member 130 is configured as a connecting bolt that passes through the upper cross beam 220 of the front frame 200. The connecting bolts are arranged at intervals in the left-right direction of the upper cross beam 220, for example, symmetrically with respect to the longitudinal center line of the front frame 200. In addition, a plurality of connecting bolts, for example, two connecting bolts, may be arranged on one side in the left-right direction, and spaced in the up-down direction to improve the connection stability.

[0044] The present application also relates to a front-end module. The front-end module includes a front-end frame and the above-mentioned device for fixing the front-end frame. The front-end module is fixed by the above-mentioned device for fixing the front-end frame, and is stable, has high rigidity, and has good load-bearing effect.

[0045] In addition, preferably, Figure 5 As shown, a reinforcing mechanism 211 is provided at the connection between the lower cross beam 210 of the front frame 200 and the first connecting member 110. For example, the lower cross beam 210 at this location is thickened relative to the main body of the lower cross beam 210 to form the reinforcing mechanism 211. When the lower cross beam 210 is a pipe column structure, the reinforcing mechanism 211 can also be a rib plate provided in the inner cavity of the pipe column. This arrangement can improve the rigidity of the connection of the lower cross beam 210 and further increase the fixing stability of the front frame 200.

[0046] In the present application, the front-end frame 200 adopts a three-layer fixing scheme, specifically, upper fixing, middle fixing, and bottom fixing, with an optimized structure and good load-bearing effect, which can effectively ensure the stability of the front-end frame 200 itself, and then ensure the stability of the functional components thereon. For example, through multiple first connectors 110, the overall rigidity of the lower part of the front-end module is strengthened, and the support of the lower part of the front-end frame 200 for the cooling module is increased, thereby avoiding the problem of abnormal noise and loss of function of the car caused by the sinking of the front-end module.
