[0033] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0034] Please also read Figures 1 to 5, the radiator upper crossbeam mounting structure provided by the utility model is now described. The radiator upper crossbeam mounting structure comprises a radiator upper crossbeam mounting plate 3, a radiator upper crossbeam mounting conversion bracket 2 and a radiator upper crossbeam assembly 1, wherein the radiator upper crossbeam mounting conversion bracket 2 is connected to the radiator upper crossbeam mounting plate 3 by a first bolt; the radiator upper crossbeam assembly 1 is connected to the radiator upper crossbeam mounting conversion bracket 2 by a second bolt; the radiator upper crossbeam assembly 1 is provided with a radiator upper crossbeam mounting plate 3 and the radiator upper crossbeam mounting conversion bracket 2 at both ends of the left and right ends; the radiator upper crossbeam mounting conversion bracket 2 is provided with a first adjustment hole group 21 for the first bolt to pass through and a second adjustment hole group 22 for the second bolt to pass through.

[0035] Compared with the prior art, the radiator upper crossbeam mounting structure provided by the utility model has the following beneficial effects: the radiator upper crossbeam mounting plate 3 is first fixed to the vehicle body side beam, and then the radiator upper crossbeam mounting conversion bracket 2 is fixed to the radiator upper crossbeam mounting plate 3 by a first bolt, and finally, the radiator upper crossbeam assembly 1 is fixed to the radiator upper crossbeam mounting conversion bracket 2 by a second bolt. This fixing method of sequential connection by bolts can shorten the dimension chain of the cabin assembly, thereby reducing the value of the accumulated assembly tolerance; since the radiator upper crossbeam mounting plate 3 is fixed to On the body side beam, the accumulated assembly tolerance of the cabin is accumulated on the radiator upper beam mounting plate 3. Through the first adjustment hole group 21 of the radiator upper beam conversion bracket, the installation position of the radiator upper beam conversion bracket can be adjusted to absorb the assembly tolerance accumulated in the cabin to the radiator upper beam mounting plate 3, thereby ensuring the installation accuracy of the radiator upper beam assembly 1, and thus achieving a good matching effect between the front guard of the cabin and the hood; at the same time, the combination of bolt connection and adjustment hole group makes the installation dimension adjustment of the entire dimension chain simple and easy, and can also effectively improve the convenience of later maintenance.

[0036] The installation sequence of the present application is to install the radiator upper crossbeam mounting plate 3, the radiator upper crossbeam mounting conversion bracket 2 and the radiator upper crossbeam assembly 1 in sequence from bottom to top. During installation, the radiator upper crossbeam mounting plate 3 is first welded to the body side beam. During welding, the radiator upper crossbeam mounting plate 3 is positioned with the help of the third positioning hole group 33 on the radiator upper crossbeam mounting plate 3 to ensure the accuracy of the installation position of the radiator upper crossbeam mounting plate 3; then the radiator upper crossbeam mounting conversion bracket 2 is fixed to the radiator upper crossbeam mounting plate 3 by the first bolt. At this time, the position of the radiator upper crossbeam mounting conversion bracket 2 can be adjusted front and back, left and right with the help of the first adjustment hole group 21 to absorb the assembly tolerance; finally, the radiator upper crossbeam assembly 1 is fixed to the radiator upper crossbeam mounting conversion bracket 2 by the second bolt. This method of absorbing the accumulated assembly tolerance of the cabin by installing the conversion bracket 2 on the radiator upper crossbeam avoids the radiator upper crossbeam assembly 1 being directly fixed on the radiator upper crossbeam mounting plate 3, and avoids the accumulated assembly tolerance of the cabin being transferred to the radiator upper crossbeam assembly 1, thereby causing a large installation position error of the radiator upper crossbeam assembly 1, thereby avoiding affecting the matching of the cabin front guard and the hood.

[0037] In some embodiments, Figure 2 As shown, a first mounting hole group 31 for the first bolt to pass through is provided on the radiator upper beam mounting plate 3, and the first mounting hole group 31 includes three first mounting holes, and the center lines of the three first mounting holes form a triangle shape; the first adjustment hole group 21 includes three first adjustment holes; the positions of the three first mounting holes correspond one to one with the positions of the three first adjustment holes, the aperture of the first mounting hole is adapted to the nominal diameter of the first bolt, and the aperture of the first adjustment hole is larger than the nominal diameter of the first bolt, so as to absorb the accumulated tolerance by means of the adjustable position of the radiator upper beam mounting conversion bracket 2.

[0038] A first adjustment hole with a hole diameter larger than that of the first bolt is provided on the radiator upper crossbeam mounting conversion bracket 2. When installing the radiator upper crossbeam mounting conversion bracket 2, the position can be adjusted frontward, rearward, leftward, and rightward to find the exact position for installing the radiator upper crossbeam assembly 1, thereby reducing or avoiding assembly errors of the radiator upper crossbeam assembly 1.

[0039] The three first mounting holes are arranged in a triangle, so that the fastening strength between the radiator upper crossbeam mounting conversion bracket 2 and the radiator upper crossbeam mounting plate 3 can be improved.

[0040] For example, the diameters of the three first mounting holes are all 7 mm, and the diameters of the three first adjustment holes are all 9 mm-10 mm, ensuring a position adjustable range of 2 mm-3 mm to absorb the accumulated tolerance on the cabin.

[0041] In some embodiments, Figure 2As shown, the radiator upper crossbeam mounting conversion bracket 2 is also provided with a first positioning hole group 23, and the radiator upper crossbeam mounting plate 3 is also provided with a second positioning hole group 32 corresponding to the position of the first positioning hole group 23. When the radiator upper crossbeam mounting conversion bracket 2 is installed, after being clamped by a clamp, the positions of the first positioning hole group 23 and the second positioning hole group 32 are made to correspond, thereby improving the convenience of connecting the two.

[0042] Furthermore, the first positioning hole group 23 includes two first positioning holes, wherein the radiator upper crossbeam mounting conversion bracket 2 is a component with a symmetrical structure, so that the radiator upper crossbeam mounting conversion bracket 2 can be shared by the left and right sides.

[0043] For example, the diameters of the two first positioning holes are both 8-10 mm.

[0044] In some embodiments, Figure 2 As shown, the radiator upper crossbeam mounting plate 3 is also provided with a third positioning hole group 33 for mounting and positioning with the body side beam. Since the accuracy of the mounting position of the radiator upper crossbeam mounting plate 3 affects the accuracy of the mounting position of the radiator upper crossbeam mounting conversion bracket 2, and the mounting position of the radiator upper crossbeam assembly 1 is affected by the position of the radiator upper crossbeam mounting conversion bracket 2, the mounting position accuracy of the radiator upper crossbeam mounting plate 3 can reduce the accumulation of assembly tolerances, and the use of the third positioning hole group 33 for mounting with the body side beam can reduce the difficulty of installation and improve the installation accuracy of the radiator upper crossbeam mounting plate 3.

[0045] Optionally, the third positioning hole group 33 arranged on the radiator upper beam mounting plate 3 includes a third main positioning hole 331 and a third auxiliary positioning hole 332, and the aperture of the third main positioning hole 331 is smaller than the aperture of the third auxiliary positioning hole 332 to ensure position adjustment during positioning, thereby facilitating reducing the cumulative assembly tolerance.

[0046] Exemplarily, the diameter of the third main positioning hole 331 is 8 mm, and the diameter of the third auxiliary positioning hole 332 is 10 mm.

[0047] In some embodiments, Figure 2As shown, the second adjustment hole group 22 includes two second adjustment holes 221 and a first pre-hanging mounting hole 222, and the center line of the two second adjustment holes 221 and the first pre-hanging mounting hole 222 forms a triangle shape; the left and right ends of the radiator upper beam assembly 1 are respectively provided with second mounting hole groups 121 for the second bolt to pass through, and the second mounting hole group 121 includes a second pre-hanging mounting hole 1211, a second positioning mounting hole 1212 and a second mounting hole 1213; the position of the second pre-hanging mounting hole 1211 corresponds to the first pre-hanging mounting hole 222; the positions of the second positioning mounting hole 1212 and the second mounting hole 1213 correspond to the two second adjustment holes 221 one by one, and the aperture of the second positioning mounting hole 1212 is adapted to the nominal diameter of the second bolt, and the aperture of the second adjustment hole 221 is larger than the nominal diameter of the second bolt; the aperture of the second mounting hole 1213 is larger than the aperture of the second adjustment hole 221.

[0048] In this embodiment, through a second pre-hanging installation hole 1211 on the radiator upper beam assembly 1, during installation, the radiator upper beam assembly 1 can be pre-hanged on the radiator upper beam installation conversion bracket 2 to reduce the difficulty of installation, and then the second bolt is passed through the second positioning installation hole 1212 to accurately locate the installation position of the radiator upper beam assembly 1; and the reserved apertures of the second installation hole 1213 and the second adjustment hole 221 facilitate the position adjustment between the two to absorb the assembly tolerance.

[0049] At the same time, the three triangular mounting points can improve the firmness of the crossbeam assembly 1 on the radiator.

[0050] The radiator upper crossbeam assembly 1 comprises a radiator upper crossbeam body 11 and a radiator upper crossbeam reinforcement plate 12 , and the second mounting hole group 121 is arranged on the radiator upper crossbeam reinforcement plate 12 .

[0051] Exemplarily, the apertures of the second adjustment holes 221 are all 7 mm, the apertures of the second mounting holes 1213 are all 10 mm, and the apertures of the second positioning mounting holes 1212 are all 6.2 mm.

[0052] In some embodiments, Figure 2 As shown, the diameter of the second pre-hanging installation hole 1211 is larger than the diameter of the first pre-hanging installation hole 222. When the pre-hanging bolt is set on the first pre-hanging installation hole 222, the diameter of the second pre-hanging installation hole 1211 is larger than the pre-hanging bolt, which facilitates the hanging of the second pre-hanging installation hole 1211.

[0053] Exemplarily, the diameter of the second pre-hanging installation hole 1211 is 10 mm, and the diameter of the first pre-hanging installation hole 222 is 5.4 mm.

[0054] In some embodiments, Figure 1 and Figure 2As shown, at least one of the second positioning and mounting holes 1212 at the left and right ends of the radiator upper crossbeam assembly 1 is an oblong hole 1214, and the width of the oblong hole 1214 is adapted to the nominal diameter of the second bolt. That is, one of the two second positioning and mounting holes 1212 is designed to be an adjustable oblong hole 1214. For example, when the left end of the radiator upper crossbeam assembly 1 is an oblong hole 1214, at this time, the right end of the radiator upper crossbeam assembly 1 can be positioned through the second positioning and mounting hole 1212, and the left end of the radiator upper crossbeam assembly 1 can be used as an assembly tolerance absorption end, and the purpose of reducing the assembly tolerance of the radiator upper crossbeam assembly 1 is achieved by adjusting the oblong hole 1214.

[0055] Optionally, the oblong hole 1214 has a width of 6.2 mm and a length of 11 mm.

[0056] In some embodiments, Figure 2 As shown, a reinforcing rib structure is provided on the radiator upper crossbeam mounting conversion bracket 2 to improve the rigidity of the radiator upper crossbeam mounting conversion bracket 2, thereby ensuring the accuracy of the installation position of the radiator upper crossbeam assembly 1. Preferably, the reinforcing rib structure is also symmetrically arranged.

[0057] In some embodiments, Figure 2 and Figure 5 As shown, the radiator upper crossbeam mounting plate 3 is a box-shaped structure, which can ensure the firmness of the radiator upper crossbeam mounting plate 3 and the body side beam, and ensure the installation accuracy of the radiator upper crossbeam mounting plate 3.

[0059] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including the above-mentioned radiator upper crossbeam mounting structure.

[0060] The vehicle provided by the embodiment of the utility model adopts the radiator upper cross beam installation conversion bracket 2 as the intermediate connection during the installation of the radiator upper cross beam, thereby absorbing the assembly tolerance accumulated in the engine room and shortening the dimensional assembly chain, thereby ensuring the matching accuracy between the engine room front guard and the engine cover and improving the visibility of the front appearance of the entire vehicle.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
