[0010] In one embodiment, the front-end module includes a second cross beam, the second cross beam is located on a side of the first cross beam away from the mounting hole along the third direction, and two ends of the second cross beam along the second direction are detachably connected to the two longitudinal beams in a one-to-one correspondence;

[0011] The second cross beam is provided with a first waist-shaped hole, which extends along the third direction. The frame is provided with a first positioning pin, which passes through the first waist-shaped hole. The size of the first waist-shaped hole along the third direction is larger than the size of the first positioning pin along the third direction.

[0012] In one of the embodiments, the second cross beam is provided with a plurality of the first waist-shaped holes spaced apart along the second direction, and the first positioning pin is passed through any one of the first waist-shaped holes.

[0013] In one embodiment, the front-end module includes a mounting frame, two mounting frames are arranged one by one on both sides of the first beam along the second direction, and each mounting frame is detachably connected to the first beam;

The positioning member passes through the mounting hole and cooperates with the positioning hole on the vehicle body to mount the front-end module on the vehicle body. During this process, since the front-end module is detachably connected to the height-adjusting assembly and can be connected to any position of the height-adjusting assembly along the gravity direction, the staff can mount the front-end module on the height-adjusting assembly to maintain the position relationship between the front-end module and the vehicle body in the gravity direction when the frame is removed from the vehicle body, thereby ensuring the position of the front-end module relative to the vehicle body in the gravity direction.

The dimension of one of the two first positioning holes along the second direction is greater than the dimension of the corresponding third positioning pin along the second direction.

[0024] In the tooling assembly of this embodiment, the third positioning pin on the frame body passes through the first positioning hole on the fender. The dimension of one of the two first positioning holes in the second direction is greater than the dimension of the corresponding third positioning pin in the second direction, which facilitates the two third positioning pins to quickly pass through the corresponding first positioning holes on the fender. The frame body is positioned on the fender through the third positioning pins. The front-end module is connected to one side of the frame body in the first direction. The frame body ensures the position of the front-end module relative to the vehicle body in the vehicle body length direction and width direction. The positioning member passes through the mounting hole and cooperates with the second positioning hole on the vehicle body to install the front-end module on the vehicle body. During this process, since the front-end module is detachably connected to the height-adjusting component and can be connected to any position of the height-adjusting component along the gravity direction, the staff can install the front-end module on the height-adjusting component to maintain the position relationship between the front-end module and the vehicle body in the gravity direction when the frame body is removed from the fender, thereby ensuring the position of the front-end module relative to the vehicle body in the gravity direction. In summary, in this embodiment, by setting the height-adjusting component, the front-end module is detachably connected to the height-adjusting component and can be connected to any position of the height-adjusting component along the gravity direction, so as to maintain the distance between the front-end module and the vehicle body in the gravity direction as the target value when the frame body is removed from the fender, thereby improving the installation accuracy of the front-end module in the gravity direction, improving the overall installation accuracy of the vehicle, and improving the appearance quality of the vehicle.

[0047] Please refer to Figure 1 , Figure 1The structural schematic diagram of the tooling assembly in an embodiment of the present application is shown. A positioning tooling 1100 provided in an embodiment of the present application includes: a frame body 1110, a front-end module 1120, and a height-adjusting component 1130. A positioning component (not shown) is provided on the frame body 1110. The positioning component is used to position the frame body 1110 on the vehicle body 1300. The front-end module 1120 is located on one side of the frame body 1110 along the first direction. The front-end module 1120 is connected to the frame body 1110. An installation hole 1123 and a positioning member 1133 are provided on the front-end module 1120. Both the positioning member 1133 and the installation hole 1123 extend along the first direction. The first direction is the gravity direction. The positioning member 1133 passes through the installation hole 1123 and is used to cooperate with a positioning hole (not shown) on the vehicle body 1300. The height-adjusting component 1130 extends along the first direction. The front-end module 1120 is detachably connected to the height-adjusting component 1130 and can be connected to any position of the height-adjusting component 1130 along the first direction.

[0048] In the positioning tooling 1100 of this embodiment, the frame body 1110 is positioned on the vehicle body 1300. The front-end module 1120 is connected to one side of the frame body 1110 along the first direction. The frame body 1110 ensures the position of the front-end module 1120 relative to the vehicle body 1300 in the length direction and width direction of the vehicle body 1300. The positioning member 1133 passes through the installation hole 1123 and cooperates with the positioning hole on the vehicle body 1300 to install the front-end module 1120 on the vehicle body 1300. During this process, since the front-end module 1120 is detachably connected to the height-adjusting component 1130 and can be connected to any position of the height-adjusting component 1130 along the gravity direction, the staff can install the front-end module 1120 on the height-adjusting component 1130 to maintain the position relationship between the front-end module 1120 and the vehicle body 1300 in the gravity direction when the frame body 1110 is removed from the vehicle body 1300, thereby ensuring the position of the front-end module 1120 relative to the vehicle body 1300 in the gravity direction. In summary, in this embodiment, by setting the height-adjusting component 1130, the front-end module 1120 is detachably connected to the height-adjusting component 1130 and can be connected to any position of the height-adjusting component 1130 along the gravity direction. When the frame body 1110 is removed from the vehicle body 1300, the distance between the front-end module 1120 and the vehicle body 1300 in the gravity direction can be maintained at the target value, thereby improving the installation accuracy of the front-end module 1120 in the gravity direction, improving the overall installation accuracy of the vehicle, and improving the appearance quality of the vehicle.

[0049] Please refer to Figure 2 And Figure 3In some embodiments, the front-end module 1120 includes a first cross beam 1121 and two longitudinal beams 1122. The first cross beam 1121 extends along the second direction. The two longitudinal beams 1122 are detachably arranged on both sides of the first cross beam 1121 along the second direction in a one-to-one correspondence. Each longitudinal beam 1122 extends along the third direction. Each longitudinal beam 1122 is provided with a plurality of mounting holes 1123 on the same side along the third direction. A positioning member 1133 is passed through each mounting hole 1123. Each positioning member 1133 passes through the corresponding mounting hole 1123. The first direction, the second direction and the third direction are perpendicular to each other.

[0050] In this embodiment, the front end module 1120 is fixed to the vehicle body 1300 by means of the positioning piece 1133 passing through the mounting hole 1123 on the longitudinal beam 1122 and cooperating with the positioning hole on the vehicle body 1300, thereby ensuring the position accuracy of the front end module 1120 relative to the vehicle body 1300 in the length direction and the width direction of the vehicle body 1300; the longitudinal beam 1122 and the first cross beam 1121 are detachably arranged, so that when the staff repairs and replaces the longitudinal beam 1122, it is unnecessary to remove the front end module 1120 as a whole from the vehicle body 1300 every time, but only needs to remove the longitudinal beam 1122 from the first cross beam 1121, which greatly facilitates the repair and replacement of the longitudinal beam 1122.

[0051] In some embodiments, the first cross beam 1121 is provided with a plurality of first assembly holes (not shown) on both sides along the second direction, and each of the two longitudinal beams 1122 is provided with a plurality of first disassembly holes (not shown). The plurality of first disassembly holes are arranged in one-to-one correspondence with the plurality of first assembly holes, and each first disassembly hole is connected to the corresponding first assembly hole through a first fastener (not shown). Optionally, the first fixing member can adopt common fastening devices such as bolts and screws.

[0052] See also Figure 2 and Figure 3 In some embodiments, the front-end module 1120 includes a second cross beam 1124, which is located on the side of the first cross beam 1121 away from the mounting hole 1123 along the third direction. The two ends of the second cross beam 1124 along the second direction are detachably connected to the two longitudinal beams 1122 one by one. The second cross beam 1124 is provided with a first waist-shaped hole 1125, and the first waist-shaped hole 1125 extends along the third direction. The frame 1110 is provided with a first positioning pin (not shown), which is passed through the first waist-shaped hole 1125. The size of the first waist-shaped hole 1125 along the third direction is larger than the size of the first positioning pin along the third direction.

[0053] In this embodiment, by setting the second cross beam 1124 to be detachably connected to the two longitudinal beams 1122, when the staff repairs and replaces the second cross beam 1124, it is not necessary to remove the front end module 1120 as a whole from the vehicle body 1300 every time. It is only necessary to remove the second cross beam 1124 from the longitudinal beam 1122, which greatly facilitates the replacement and maintenance of the second cross beam 1124; by setting the size of the first waist-shaped hole 1125 along the third direction to be larger than the size of the first positioning pin along the third direction, the staff can drive the front end module 1120 to move relative to the frame 1110 along the third direction, thereby changing the relative position of the front end module 1120 and the frame 1110 in the third direction, eliminating the deviation between the actual relative position and the target relative position of the front end module 1120 and the frame 1110 in the third direction, ensuring the accuracy of the relative position of the front end module 1120 and the vehicle body 1300 in the third direction, reducing the requirements for the dimensional accuracy of the vehicle body 1300, and alleviating the manufacturing cost and difficulty of the vehicle body 1300.

[0054] In some embodiments, the second cross beam 1124 is provided with a plurality of second assembly holes (not shown) on both sides along the second direction, and each of the two longitudinal beams 1122 is provided with a plurality of second disassembly holes (not shown), and the plurality of second disassembly holes are arranged in one-to-one correspondence with the plurality of second assembly holes, and each second disassembly hole is connected to the corresponding second assembly hole through a second fastener (not shown), and the second fastener can be a common fastening device such as a bolt or a screw.

[0055] In some embodiments, the second beam 1124 is provided with a first positioning step 1124-1 on the side close to the frame 1110 along the first direction, and the first positioning step 1124-1 is provided with a first positioning surface (not shown) on the side away from the second beam 1124 along the first direction, and the first positioning surface is in contact with the frame 1110. By providing the first positioning step 1124-1, the second beam 1124 is close to the side of the frame 1110 and does not need to be in contact with the frame 1110 in its entirety, thereby reducing the processing and manufacturing cost of the second beam 1124, that is, the staff only needs to ensure the dimensional accuracy of the first positioning surface.

[0056] See also Figure 3 In some embodiments, the second cross beam 1124 is provided with a plurality of first waist-shaped holes 1125 spaced apart along the second direction, and the first positioning pin is passed through any one of the first waist-shaped holes 1125 .

[0057] In this embodiment, by passing the first positioning pin through different first waist-shaped holes 1125 on the second crossbeam 1124, the relative position between the front-end module 1120 and the frame body 1110 in the second direction can be changed, eliminating the deviation between the actual relative position and the target relative position of the front-end module 1120 and the frame body 1110 in the second direction, and ensuring the accuracy of the relative position between the front-end module 1120 and the vehicle body 1300 in the second direction. To sum up, a plurality of first waist-shaped holes 1125 are arranged at intervals in the second direction, and the dimension of each first waist-shaped hole 1125 in the third direction is greater than the dimension of the first positioning pin in the third direction, enabling the staff to simultaneously change the relative positions of the front-end module 1120 and the vehicle body 1300 in the second and third directions, ultimately making the mounting holes 1123 on the front-end module 1120 and the corresponding positioning holes on the vehicle body 1300 coaxial and collinear, improving the overall installation accuracy of the vehicle and enhancing the appearance quality of the vehicle.

[0058] Please continue to refer to Figure 3 , in some embodiments, the front-end module 1120 includes a mounting frame 1126. Two mounting frames 1126 are respectively arranged on both sides of the first crossbeam 1121 along the second direction. Each mounting frame 1126 is detachably connected to the first crossbeam 1121. A second waist-shaped hole 1127 is provided on one side of each mounting frame 1126 close to the frame body 1110 along the first direction. The second waist-shaped hole 1127 extends along the second direction. A second positioning pin (not shown) is provided on the frame body 1110, and the second positioning pin passes through the second waist-shaped hole 1127. The dimension of the second waist-shaped hole 1127 in the second direction is greater than the dimension of the second positioning pin in the second direction.

[0059] In this embodiment, by setting the mounting frame 1126 to be detachably connected to the first crossbeam 1121, when the staff repairs and replaces the mounting frame 1126, it is not necessary to remove the entire front-end module 1120 from the vehicle body 1300 each time. It is only necessary to remove the mounting frame 1126 from the first crossbeam 1121, which greatly facilitates the replacement and repair of the mounting frame 1126. By setting the dimension of the second waist-shaped hole 1127 in the second direction to be greater than the dimension of the second positioning pin in the second direction, on the one hand, it is convenient to pass the second positioning pin through the second waist-shaped hole 1127. On the other hand, it enables the staff to drive the front-end module 1120 to move relative to the frame body 1110 in the second direction, thereby changing the relative position between the front-end module 1120 and the frame body 1110 in the second direction, eliminating the deviation between the actual relative position and the target relative position of the front-end module 1120 and the frame body 1110 in the second direction, ensuring the accuracy of the relative position between the front-end module 1120 and the vehicle body 1300 in the second direction, reducing the requirement for the dimensional accuracy of the vehicle body 1300, and reducing the manufacturing cost and difficulty of the vehicle body 1300.

[0060] It should be further explained that the mounting frame 1126 can be used to install lamps.

[0061] In some embodiments, the first beam 1121 is provided with a plurality of third assembly holes (not shown) on both sides along the second direction, and each of the two mounting frames 1126 is provided with a plurality of third disassembly holes (not shown), and the plurality of third disassembly holes are arranged in one-to-one correspondence with the plurality of third assembly holes, and each third disassembly hole is connected to the corresponding third assembly hole through a third fastener (not shown), and the third fastener can be a common fastening device such as a bolt or a screw.

[0062] In some embodiments, the mounting frame 1126 is provided with a second positioning step 1126-1 on one side close to the frame 1110 along the first direction, and the second positioning step 1126-1 is provided with a second positioning surface (not shown) on the side away from the mounting frame 1126 along the first direction, and the second positioning surface is in contact with the frame 1110. By providing the second positioning step 1126-1, the mounting frame 1126 is close to one side of the frame 1110 without having to contact the entire side of the frame 1110, thereby reducing the processing and manufacturing cost of the mounting frame 1126, that is, the staff only needs to ensure the dimensional accuracy of the second positioning surface.

[0063] Please continue reading Figure 3 In some embodiments, each mounting frame 1126 is provided with a plurality of second waist-shaped holes 1127 arranged at intervals along a third direction and close to one side of the frame body 1110 along the first direction, and the second positioning pin is passed through any one of the second waist-shaped holes 1127 .

[0064] In this embodiment, by allowing the second locating pin to pass through different second waist-shaped holes 1127 on the mounting frame 1126, the relative position of the front-end module 1120 and the frame 1110 in the third direction can be changed, and the deviation between the actual relative position and the target relative position of the front-end module 1120 and the frame 1110 in the third direction can be eliminated, thereby ensuring the accuracy of the relative position of the front-end module 1120 and the vehicle body 1300 in the third direction. In summary, a plurality of second waist-shaped holes 1127 are arranged at intervals along the third direction, and the size of each second waist-shaped hole 1127 along the second direction is larger than the size of the second locating pin along the second direction, so that the staff can simultaneously change the relative position of the front-end module 1120 and the vehicle body 1300 in the second and third directions, and finally achieve the coaxial and collinearity of the mounting hole 1123 on the front-end module 1120 and the corresponding locating hole on the vehicle body 1300, thereby improving the overall installation accuracy of the automobile and improving the appearance quality of the automobile.

[0065] See also Figures 4 to 6In some embodiments, the height adjustment component 1130 includes a plurality of height adjustment members 1131, and the plurality of height adjustment members 1131 are arranged in a one-to-one correspondence with the plurality of mounting holes 1123. Each height adjustment member 1131 extends along a first direction, and each height adjustment member 1131 is passed through a corresponding mounting hole 1123 and is threadedly connected to the corresponding mounting hole 1123.

[0066] In this embodiment, the height adjusting parts 1131 are all inserted into the corresponding mounting holes 1123 and threadedly connected with the corresponding mounting holes 1123, so that the staff can install the front end module 1120 at any position of the height adjusting part 1131 along the first direction by tightening and loosening the height adjusting part 1131, and then when the frame 1110 is removed from the vehicle body 1300, the relative position of the front end module 1120 and the vehicle body 1300 in the gravity direction is maintained. The above method has a simple structure, low cost and strong practicality; the positioning part 1133 passes through the height adjusting through hole 1132 and cooperates with the positioning hole on the vehicle body 1300, so that the front end module 1120 can be fixed to the vehicle body 1300, thereby ensuring the position of the front end module 1120 relative to the vehicle body 1300 in the length direction and width direction of the vehicle body 1300, thereby improving the overall installation accuracy of the automobile and improving the appearance quality of the automobile.

[0067] See also Figure 6 In some embodiments, the positioning member 1133 includes a positioning shaft (not shown), the positioning shaft includes a first shaft segment 1133-1 and a second shaft segment 1133-2 that are coaxially arranged and interconnected, the first shaft segment 1133-1 is arranged on a side of the height adjusting member 1131 close to the frame 1110 along the first direction, the axis of the first shaft segment 1133-1 and the axis of the height adjusting through hole 1132 are located on the same straight line, and the diameter of the first shaft segment 1133-1 is larger than the diameter of the height adjusting through hole 1132, and the second shaft segment 1133-2 passes through the height adjusting through hole 1132 along the axial direction of the first shaft segment 1133-1.

[0068] In this embodiment, the second shaft segment 1133-2 passes through the height adjustment hole 1132 and cooperates with the positioning hole on the vehicle body 1300, and the first shaft segment 1133-1 abuts against the first shaft segment 1133-1, pressing the height adjustment member 1131 against the vehicle body 1300 to prevent the height adjustment member 1131 from driving the front end module 1120 connected thereto to swing relative to the vehicle body 1300 along the first direction.

[0069] See also Figure 7, in some embodiments, the positioning component includes two third positioning pins (not shown), and the two third positioning pins are respectively disposed on two sides of the frame body 1110 along the second direction, and each third positioning pin extends along the first direction.

[0070] In this embodiment, the frame body 1110 is fixed to the vehicle body 1300 through the third positioning pins.

[0071] Please refer to Figure 1 and Figure 7 , Figure 1 FIG. shows a schematic structural diagram of a tooling component in an embodiment of the present application. A tooling component 1000 provided in an embodiment of the present application includes the aforementioned positioning tooling 1100, a vehicle body 1300, and a pair of fenders 1200. The vehicle body 1300 is provided with second positioning holes 1310. The positioning member 1133 passes through the mounting hole 1123 and cooperates with the second positioning holes 1310 on the vehicle body 1300. The pair of fenders 1200 are spaced apart on opposite sides of the vehicle body 1300. Each fender 1200 is provided with a first positioning hole 1210. The two third positioning pins are correspondingly arranged with the pair of fenders 1200. Each third positioning pin penetrates into the first positioning hole 1210 on the corresponding fender 1200. The dimension of one of the two first positioning holes 1210 along the second direction is larger than the dimension of the corresponding third positioning pin along the second direction.

[0072] In the tooling assembly 1000 of this embodiment, the third positioning pin on the frame 1110 passes through the first positioning hole 1210 on the fender 1200. The dimension of one of the two first positioning holes 1210 in the second direction is greater than the dimension of the corresponding third positioning pin in the second direction, which facilitates the rapid insertion of the two third positioning pins into the corresponding first positioning holes 1210 on the fender 1200. The frame 1110 is positioned on the fender 1200 through the third positioning pin. The front-end module 1120 is connected to one side of the frame 1110 in the first direction. The frame 1110 ensures the position of the front-end module 1120 relative to the vehicle body 1300 in the length direction and width direction of the vehicle body 1300. The positioning member 1133 passes through the mounting hole 1123 and cooperates with the second positioning hole 1310 on the vehicle body 1300 to install the front-end module 1120 on the vehicle body 1300. During this process, since the front-end module 1120 is detachably connected to the height-adjusting assembly 1130 and can be connected to any position of the height-adjusting assembly 1130 in the direction of gravity, the staff can install the front-end module 1120 on the height-adjusting assembly 1130 to maintain the positional relationship between the front-end module 1120 and the vehicle body 1300 in the direction of gravity when the frame 1110 is removed from the fender 1200, thereby ensuring the position of the front-end module 1120 relative to the vehicle body 1300 in the direction of gravity. In summary, in this embodiment, by setting the height-adjusting assembly 1130, the front-end module 1120 is detachably connected to the height-adjusting assembly 1130 and can be connected to any position of the height-adjusting assembly 1130 in the direction of gravity, so as to maintain the distance between the front-end module 1120 and the vehicle body 1300 in the direction of gravity as the target value when the frame 1110 is removed from the fender 1200, thereby improving the installation accuracy of the front-end module 1120 in the direction of gravity, improving the overall installation accuracy of the vehicle, and improving the appearance quality of the vehicle.
