Problems solved by technology

[0003] see image 3 and Figure 4 , when the door lock installed in the tapered hole is changed to the flat hole installation, the existing flat head bolt 9 is used to realize the fixed connection between the lock body 5 and the door sheet metal 7, because the depth of the groove and the height of the bolt head of the existing flat head bolt 9 are adopted Only when the national standard is met can the installation torque requirements be met, and the bolt head will protrude farther S3 from the door sheet metal surface, resulting in a reduction in the theoretical safety distance between the bolt head of the existing flat head bolt 9 and the lock pin bottom plate 61
[0004] At the same time, the appearance of the car has gaps, surface differences, etc. DTS, that is, technical specifications for dimensions, and its related components and assemblies have manufacturing tolerances. Adjust the attitude of the door, etc. This adjustment process will affect the gap between the bolt pan head and the door lock pin, that is, the actual vehicle gap may be larger or smaller than the theoretical design value

Embodiment Construction

[0027] The application will be described in detail below in conjunction with the accompanying drawings.

[0028] see Figure 5 to Figure 7 , the car door lock fastening bolt shown includes an integrally formed bolt head 1 and a screw rod 2, the screw rod 2 is provided with a threaded section 3, the bolt head 1 is provided with a through hole 11 penetrating in the axial direction, the A groove 21 is provided at the position corresponding to the end of the screw 2 and the through hole 11, and the opening of the groove 21 communicates with the through hole 11, and the through hole 11 and the groove 21 together form a fastening groove that is compatible with the fastening tool . Furthermore, the height dimension of the bolt head 1 can be significantly reduced without reducing the tightening torque value that the bolt can bear, that is, the bolt head 1 is thinned, so that the height S1 of the bolt head 1 protruding from the surface of the door sheet metal 7 is equivalent to Compa...

Abstract

The invention discloses a vehicle door lock fastening bolt and a vehicle. The vehicle door lock fastening bolt comprises a bolt head and a screw rod which are integrally formed, a threaded section is arranged on the screw rod, a through hole penetrating in the axial direction is formed in the bolt head, a groove is formed in the position, corresponding to the through hole, of the end of the screw rod, an opening of the groove communicates with the through hole, and the through hole and the groove jointly form a fastening groove matched with a fastening tool. By means of the vehicle door lock fastening bolt, under the condition that the value of fastening torsion capable of being borne by the bolt is not reduced, the height size of the bolt head can be reduced, that is, the bolt head is thinned, and the safety gap between the bolt and peripheral parts is increased.

Description

technical field [0001] The invention relates to a fastener, in particular to a door lock fastening bolt and a vehicle. Background technique [0002] Existing car door locks for automobiles, the car door lock assembly includes a lock body 5 and a lock pin 6 that are compatible with each other, the lock body 5 is fixed on the door sheet metal 7 by fastening bolts, and the lock pin 6 is fixed on the car body Above, the lock pin 6 includes a lock pin base plate 61 and a lock pin U-shaped column 62 fixed on the lock pin base plate 61 and correspondingly matched with the lock body 5. There are two types of fastener mounting holes on the door lock base plate of the lock body 5 , that is, a tapered hole and a flat hole. see figure 1 and figure 2 , the mounting hole of the fastener on the door lock substrate of the lock body 5 is a tapered hole, that is, the existing conical head bolt 8 is used to realize the fixed connection between the lock body 5 and the door sheet metal 7, in...
