Embodiment 1

[0035] Number 24 is the threaded connection hole that the door lock device is fastened and connected with the mounting screw.

[0036] The door inner panel 3 and the door lock reinforcement plate 2 are processed into inwardly recessed tapered holes through the position of the mounting screws 4 through the stamping process, the door inner panel 3 and the door lock reinforcement plate 2 are welded and connected, and the door lock is threaded through the mounting screws 4 On the inner panel 3 of the car door. The surface of the nut of the mounting screw 4 is flush with the inner panel 3 of the car door, and the lower bottom surface of the nut protrudes downward to form a spherical crown shape. The lower bottom surface of the nut and the tapered hole have a larger bonding area. Design the tapered hole of the car door inner panel 3 to interfere with the door lock in advance. The pre-interference is about 0.4mm-0.8mm. When the door lock is installed to the designed position, the ...

Embodiment 2

[0039] like Figure 4 As shown, there is no bottom plate 19 in the mounting portion 13, instead, the positioning hole 17 on the door lock device 1 is hexagonal. The threaded slider 25 includes an upper part 21 of the threaded slider and a lower part 22 of the threaded slider. The upper part 21 of the threaded slider is inserted into the positioning hole 17 of the door lock device. The hexagons and hexagonal prisms here are only for illustration, and in practical applications, any shape that can make the threaded slider 25 not rotate with the threaded rod 16 can be adopted.

[0040] The mechanical arm firstly attaches the door lock device 1 to the threaded rod 16, and then abuts each threaded rod 16 in the positioning groove 18. After the alignment is completed, the motor 15 works. Due to the existence of multiple connection points, the door lock device 1 does not occur. Instead, the rotation of the threaded rod 16 is converted into a forward and backward movement of the thre...

Abstract

The invention discloses an automobile door and door lock connection structure and an assistant positioning device for the automobile door and door lock connection structure, and aims at solving the shortage that the length of an automobile in the Y direction is relatively large due to the fact that an interval needs to be left in an existing automobile door and door lock connection structure for aseal ring and an installation screw. The automobile door and door lock connection structure comprises a door lock device, a door lock reinforcement plate and an automobile door inner plate, wherein the door lock device, the door lock reinforcement plate and the automobile door inner plate are connected through the installation screw, the lower bottom face of a nut of the installation screw is ina ball crown shape, the installation screw is in threaded connection onto a mounting seat formed by the door lock device and the automobile door inner plate, the mounting seat is a concave ball-crown-shaped mounting seat which fits the bottom of the nut of the installation screw, and the surface of the installation screw is lower than the automobile door inner plate. The automobile door and door lock connection structure and the assistant positioning device for the automobile door and door lock connection structure can leave space for shortening the length of the automobile in the Y direction,avoids an interval between the automobile door inner plate and the door lock reinforcement plate, generated due to the manufacturing error, and prevents oil paint on the plates from falling off due to deformation.

Description

technical field [0001] The invention relates to automobile body parts, more specifically, it relates to an automobile door lock connection structure and an auxiliary positioning device thereof. Background technique [0002] Door structure (door structure) car door is composed of door outer panel, door inner panel, door and window frame, door glass run channel, door hinge, door lock and door and window accessories. The inner panel is equipped with glass regulators, door locks and other accessories. In order to ensure firm assembly, the inner panel must be strengthened. [0003] At present, the connection form of the inner panel of the car door and the door lock is to use fasteners to connect. This connection form has high strength and fast connection. It is often used to use flat-head screws to connect, but this connection form is firstly unsightly. The distance between the sealing strips is relatively close, and it is easy to scratch the sealing strips during the process of...
