For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0037] Reference will now be made to Figures 1-9 The heat sink cross beam mounting and positioning structure 100 according to the embodiments of the present application is described below.
[0038] As shown in Figures 1-9 The heat sink cross beam mounting and positioning structure 100 includes a front body 1, a heat sink cross beam 2, a connecting piece 3, and a positioning washer 4.
[0039] Specifically, the front body 1 has a first connecting hole 12, the radiator cross beam 2 has a second connecting hole 21, and the connecting piece 3 is arranged in the first connecting hole 12 and the second connecting hole 21, and is used to connect the front body 1 and the radiator cross beam 2. The positioning pad 4 is fixedly connected with the radiator cross beam 2, and the positioning pad 4 has a positioning hole 41 for the connecting piece 3 to pass through. It can be understood that the connecting piece 3 is also arranged in the positioning hole 41 of the positioning pad 4. The diameter of the second connecting hole 21 is greater than the diameter of the positioning hole 41, and the diameter of the positioning hole 41 is greater than or equal to the diameter of the connecting piece 3.
[0040] The radiator cross beam mounting and positioning structure 100 can position the radiator cross beam 2 through a clamp in a welding workshop, so as to ensure the accuracy of the mounting points of parts such as the front cover lock, the radiator, the front bumper and the headlamp on the radiator cross beam 2. The connecting piece 3 can include a connecting bolt 31, and the diameter of the connecting piece 3 is smaller than the diameter of the second connecting hole 21. For example, the connecting bolt 31 can be M6, and the diameter of the second connecting hole 21 can be 11 mm. By making the diameter of the second connecting hole 21 greater than the diameter of the connecting piece 3, the tolerance accumulation of the radiator cross beam 2 and the front body 1 during installation can be absorbed, and the radiator cross beam 2 can be conveniently installed on the front body 1.
[0041] In the related art, in a final assembly workshop, the radiator cross beam and the connecting piece are first removed, and then the radiator cross beam is assembled on the front body using the connecting piece after the parts of the outer system (chassis, power vehicle, electrical appliances, etc.) on the front body are assembled. Since the installation of the radiator cross beam is not positioned by a clamp in the final assembly workshop, the installation accuracy of the radiator cross beam and the front body is poor, which leads to insufficient accuracy of the mounting points of parts such as the front cover lock, the radiator, the front bumper and the headlamp arranged on the radiator cross beam, and repeated assembly and adjustment are required, resulting in low production efficiency.
[0042] In the present application, by arranging the positioning pad 4 on the radiator cross beam 2, the position of the radiator cross beam 2 when it is connected to the front body 1 for the first time through a clamp can be positioned, and the position of the connecting piece 3 and the relative position of the front body 1 and the radiator cross beam 2 are locked through the positioning hole 41 smaller than the second connecting hole 21. The diameter of the positioning hole 41 can be 6.2 mm, so that the radiator cross beam 2 can be accurately positioned after being removed and reassembled in the final assembly workshop. In the final assembly workshop, special tooling is not required for accurate positioning, the accuracy of the mounting points of various parts on the radiator cross beam 2 can meet the requirements, the tooling development cost is saved, and the assembly efficiency is improved.
[0043] The radiator cross beam mounting and positioning structure 100 according to the embodiment of the utility model, through setting the positioning gasket 4 on the radiator cross beam 2, the front body 1 sets the first connecting hole 12, the radiator cross beam 2 sets the second connecting hole 21, the connecting piece 3 is arranged in the first connecting hole 12, the second connecting hole 21 and the positioning hole 41, and the aperture of the second connecting hole 21 is greater than the aperture of the positioning hole 41, the aperture of the positioning hole 41 is greater than or equal to the diameter of the connecting piece 3, the positioning gasket 4 can be used to position the position of the radiator cross beam 2 when being connected with the front body 1 by the clamp for the first time, when the radiator cross beam 2 is disassembled and reassembled subsequently, the radiator cross beam 2 can be directly assembled, without positioning tooling, under the premise that the precision of the mounting points of various parts on the radiator cross beam 2 meets the requirements, the tooling development cost is saved, and the assembly efficiency is improved.
[0044] In some embodiments of the utility model, the difference between the aperture of the positioning hole 41 and the diameter of the connecting piece 3 is 0-0.5mm. Thus, the tolerance accumulation can be absorbed during assembly, and the connecting piece 3 can be better limited, so that the mounting position of the radiator cross beam 2 is limited, and then the mounting points of the parts on the radiator cross beam 2 are limited.
[0045] In some embodiments of the utility model, when the radiator cross beam 2 and the front body 1 are connected for the first time by the clamp, the position of the positioning gasket 4 on the radiator cross beam 2 is fixed, and the radiator cross beam 2 and the positioning gasket 4 are connected. It can be understood that in the welding workshop, the radiator cross beam 2 is positioned by the clamp, and the precision of the mounting points of the parts such as the front cover lock, the radiator, the front bumper, the headlamp and the like on the radiator cross beam 2 is ensured. The aperture of the second connecting hole 21 is greater than the diameter of the connecting piece 3, and the tolerance accumulation when the radiator cross beam 2 and the front body 1 are mounted is absorbed by the large hole. The positioning gasket 4 is increased when the connecting piece 3 is assembled, the positioning hole 41 is opened in the middle of the positioning gasket 4, the positioning gasket 4 is accurately matched with the connecting piece 3 and the front body 1. After the radiator cross beam 2 is fixed to the front body 1 by using the connecting piece 3 and the positioning gasket 4, the positioning gasket 4 is welded on the radiator cross beam 2, for example, the positioning gasket 4 is welded by using CO2 protection welding, and then the radiator cross beam 2 and the body are synchronously fed into coating for electrophoretic spraying treatment.
[0046] In the assembly shop, the radiator cross beam 2 (with positioning gasket 4) and connecting piece 3 are first removed, and after the front body 1 upper outer system (chassis, power car, electrical appliances, etc.) parts are assembled, the radiator cross beam 2 (with positioning gasket 4) is assembled back to the front body 1 using the connecting piece 3. At this time, since the positioning hole 41 is provided on the positioning gasket 4, the precision of the installation points of the front cover lock, radiator, front bumper, headlamp, etc. on the radiator cross beam 2 assembly can be guaranteed. When the diameter of the second connecting hole 21 is 0.2 different from the diameter of the connecting bolt 31, the precision of the installation points of the front cover lock, radiator, front bumper, headlamp, etc. on the radiator cross beam 2 assembly is within ±0.5mm, which meets the assembly requirements of the front cover lock, radiator, front bumper, headlamp, etc.
[0047] Optionally, as shown in Figure 6 , the positioning gasket 4 is a circular gasket, of course, the utility model is not limited thereto, and the positioning gasket 4 can also be other shapes such as quadrilateral, etc.
[0048] In some embodiments of the utility model, the positioning gasket 4 is welded to the radiator cross beam 2.

[0049] In some embodiments of the utility model, as shown in Figure 8 and Figure 9 , the positioning gasket 4 is arranged on the side of the radiator cross beam 2 away from the front body 1. In this way, the positioning gasket 4 can be avoided to be located between the radiator cross beam 2 and the front body 1, which affects the reliability of the fit between the radiator cross beam 2 and the front body 1, thereby ensuring the reliability of the connection between the radiator cross beam 2 and the front body 1.
[0050] In some embodiments of the utility model, as shown in Figure 3 and Figure 8 , the front body 1 has a connecting portion 11 connected with the radiator cross beam 2, and the radiator cross beam 2 is located above the connecting portion 11. In this way, when installing the radiator cross beam 2, the radiator cross beam 2 can be moved downward from top to bottom until the installation position of the radiator cross beam 2 on the front body 1, which facilitates the installation and assembly of the radiator cross beam 2, saves assembly time, and improves production efficiency.
[0051] In some embodiments of the utility model, as shown in Figure 8As shown, the cross section of the radiator cross beam 2 and the cross section of the connecting part 11 are both arranged in an inverted U shape. The connecting part 11 and the radiator cross beam 2 arranged in a U shape have high structural strength, which can improve the reliability of supporting the components mounted on the radiator cross beam 2. The cross section of the radiator cross beam 2 and the cross section of the connecting part 11 are arranged in an inverted U shape, which facilitates the arrangement of the radiator cross beam 2 above the connecting part 11, and the upper part has a larger operation space, which facilitates the connection between the radiator cross beam 2 and the front vehicle body 1.
[0052] Further, as shown in the drawings, Figure 8 The two ends of the radiator cross beam 2 and the connecting part 11 in the width direction also have a folded edge extending away from each other, which can further improve the structural strength of the radiator cross beam 2 and the connecting part 11.
[0053] In some embodiments of the present application, as shown in the drawings, Figures 1-3 The two ends of the radiator cross beam 2 in the length direction are connected with the front vehicle body 1, the second connecting hole 21 is arranged at two positions in the length direction of the radiator cross beam 2, and the connecting piece 3, the positioning gasket 4 and the first connecting hole 12 are all corresponding two. This can improve the reliability of fixing the radiator cross beam 2, thereby improving the reliability of fixing the components on the radiator cross beam 2, and also improving the positioning accuracy of the radiator cross beam 2, thereby ensuring the accuracy of the mounting point of the components on the radiator cross beam 2.
[0054] In some embodiments of the present application, as shown in the drawings, Figures 3-9 The connecting piece 3 includes a connecting bolt 31 and a nut 32, the connecting bolt 31 is arranged in the first connecting hole 12, the second connecting hole 21 and the positioning hole 41, and the nut 32 is connected with the connecting bolt 31 and located on the side of the front vehicle body 1 away from the radiator cross beam 2. This can simplify the connection between the radiator cross beam 2 and the front vehicle body 1, and improve the reliability of the connection between the radiator cross beam 2 and the front vehicle body 1.
[0055] In the examples shown in the drawings, Figure 8 And Figure 9 The radiator cross beam 2 is located above the connecting part 11 of the front vehicle body 1, the positioning gasket 4 is located above the radiator cross beam 2 and connected with the radiator cross beam 2, the connecting bolt 31 is arranged in the positioning hole 41, the second connecting hole 21 and the first connecting hole 12 from top to bottom, and the nut 32 is located below the connecting part 11 and connected with the connecting bolt 31.
[0056] The nut 32 can be an integral part of the connecting part 11, which facilitates the connection between the connecting bolt 31 and the nut 32.
