[0053] By providing the hinge reinforcement plate 30 and connecting the bolt cap 41 of the self-positioning bolt 40 to the hinge reinforcement plate 30, when the bonnet hinge 100 is connected to the engine bonnet 200 through the self-positioning bolt 40, the hinge reinforcement plate 30 is conducive to improving the connection strength between the bonnet hinge 100 and the engine bonnet 200 and the structural strength of the engine bonnet 200, and can reduce or avoid damage to the bonnet inner plate 20 during the operation of the bonnet hinge 100. By providing the positioning hole 31 on the hinge reinforcement plate 30, the self-positioning bolt 40 can be relatively positioned with the hinge reinforcement plate 30 with reference to the positioning hole 31, which is conducive to accurately installing the self-positioning bolt 40 on the hinge reinforcement plate 30, and can improve the position accuracy of the self-positioning bolt 40.

By making the bolt column 42 include the polished rod section 421 and the threaded section 422, and making the polished rod section 421 inserted into the positioning hole 31, the through hole 21 and the first mounting hole 11, the polished rod section 421 can play the role of a positioning pin through the matching relationship between the polished rod section 421 and the positioning hole 31, the through hole 21 and the first mounting hole 11, and the polished rod section 421 can form a positioning effect on the hinge reinforcement plate 30, the hair cover inner plate 20 and the hair cover hinge 100, which can reduce or avoid the position deviation between the hinge reinforcement plate 30, the hair cover inner plate 20 and the hair cover hinge 100, which is conducive to improving the installation accuracy of the hair cover hinge 100.

[0056] refer to Figure 7-Figure 8 According to some optional embodiments of the utility model, the difference between the diameter of the positioning hole 31 and the nominal diameter of the polished rod segment 421 is a first difference, the difference between the diameter of the through hole 21 and the nominal diameter of the polished rod segment 421 is a second difference, and the difference between the diameter of the first mounting hole 11 and the nominal diameter of the polished rod segment 421 is a third difference, and the first difference and the third difference are both smaller than the second difference. By making the first difference and the third difference both smaller than the second difference, the first difference and the third difference are smaller, so that the matching accuracy between the positioning hole 31 and the polished rod segment 421 and the matching accuracy between the first mounting hole 11 and the polished rod segment 421 are higher, so that the self-positioning bolt 40 is accurately set on the hinge reinforcement plate 30, and the bonnet hinge 100 is accurately connected to the engine cover 200 through the matching of the first mounting hole 11 and the self-positioning bolt 40; the second difference is larger, which is conducive to conveniently passing the self-positioning bolt 40 through the bonnet inner plate 20.

Optionally, the first difference can be 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.18 mm, 0.2 mm, etc. By making the first difference between the diameter of the positioning hole 31 and the nominal diameter of the polished rod section 421 range from 0.1 to 0.2 mm, it is beneficial for the self-positioning bolt 40 to pass through the positioning hole 31 conveniently, and it is beneficial for the positioning hole 31 and the polished rod section 421 to have a suitable matching accuracy, so as to improve the positioning accuracy of the self-positioning bolt 40 on the hinge reinforcement plate 30, so that when the bonnet hinge 100 is subsequently positioned relative to the engine cover 200 with reference to the self-positioning bolt 40, it is also beneficial to improve the positioning accuracy and installation accuracy of the bonnet hinge 100.

[0058] refer to Figure 7-Figure 8 According to some optional embodiments of the utility model, the sum of the axial length of the positioning hole 31, the axial length of the through hole 21 and the axial length of the first mounting hole 11 is the total length of the hole, and the length of the polished rod section 421 is not greater than the total length of the hole. By making the length of the polished rod section 421 not greater than the total length of the hole, the polished rod section 421 will not exceed the first mounting hole 11. In this way, when the locking thread is connected to the threaded section 422, the end surface of the locking nut 3 close to the first mounting hole 11 can abut against the bonnet hinge 100, so as to realize the locking nut to limit the bonnet hinge 100 and the engine cover 200 along the length direction, which can reduce or avoid the bonnet hinge 100 and the engine cover 200 from moving in the length direction, which is conducive to improving the connection stability of the bonnet hinge 100 and the engine cover 200 in the length direction of the self-positioning bolt 40.

[0059] refer to Figure 7-Figure 8 According to some optional embodiments of the utility model, the length of the polished rod segment 421 in the first mounting hole 11 is the positioning length, and the ratio of the positioning length to the axial length of the first mounting hole 11 is not less than 0.5. By making the ratio of the positioning length to the axial length of the first mounting hole 11 not less than 0.5, the positioning effect of the polished rod segment 421 on the engine cover hinge 100 can be improved, thereby facilitating the installation accuracy of the engine cover hinge 100 connected to the engine cover 200.

[0060] refer to Figure 7-Figure 8 According to some optional embodiments of the utility model, the positioning holes 31 are multiple and spaced apart, the through holes 21 are multiple and spaced apart, the first mounting holes 11 are multiple and spaced apart, and the positioning holes 31, the through holes 21 and the first mounting holes 11 are arranged in a one-to-one correspondence. For example, there are two positioning holes 31 and spaced apart, there are two through holes 21 and spaced apart, there are two first mounting holes 11 and spaced apart, and the positioning holes 31, the through holes 21 and the first mounting holes 11 are arranged in a one-to-one correspondence. By setting the positioning holes 31, the through holes 21 and the first mounting holes 11 to multiple, it is beneficial to further improve the positioning accuracy between the engine cover hinge 100 and the engine cover 200, and it is beneficial to improve the connection stability between the engine cover hinge 100 and the engine cover 200.

By making the other part of the first mounting holes 11 oblong holes, the movable clearance between the mounting hole and the self-locating bolt 40 in the length direction is larger, so that the self-locating bolt 40 is not easy to be inserted into the plurality of first mounting holes 11 due to manufacturing errors or dimensional deviations.

[0062] refer to Figure 7-Figure 9According to some optional embodiments of the utility model, the bolt column 42 includes a polished rod section 421 and a threaded section 422.

[0064] By making the difference range between the diameter of the first mounting hole 11 formed as a circular hole and the nominal diameter of the polished rod section 421 be 0.1 to 0.2 mm, and making the difference range between the diameter of the first mounting hole 11 formed as an oblong hole and the nominal diameter of the polished rod section 421 be 0.1 to 0.2 mm, within this range, it is beneficial for the self-locating bolt 40 to easily pass through the two first mounting holes 11, and it is beneficial for the two first mounting holes 11 and the polished rod section 421 to have appropriate matching accuracy, so as to improve the positioning accuracy of the hood hinge 100 when positioning relative to the engine hood 200 with reference to the self-locating bolt 40.

[0065] By making the difference between the maximum dimension of the first mounting hole 11 formed as an oblong hole in the length direction of the oblong hole and the nominal diameter of the light rod section 421 be in the range of 2 to 3 mm, within this range, the movable clearance between the oblong hole and the hole and the self-locating bolt 40 in the length direction is more appropriate. On the one hand, this can avoid the difficulty of the self-locating bolt 40 being difficult to pass through the two first mounting holes 11 due to manufacturing errors or dimensional deviations, and on the other hand, it will not make the movable clearance too large to cause too low matching accuracy.
