Embodiment Construction

[0023] Attached below Figure 3-6 The present invention will be specifically described.

[0024] like Figure 3-5 As shown, the automobile door hinge of the present invention includes: a fixed leaf 1 , a movable leaf 2 and a connecting piece 3 . Fixed leaf 1 is suitable for being installed on the vehicle body structure, comprises the mounting part 11 that is installed on the vehicle body structure 103, is connected to the rotating part 14 on the mounting part 11 and the reinforcing plate 13 that is welded on the rotating part 14, and the mounting part 11 and rotating The parts 14 are connected together by rivets 12, and the rotating parts 14 can rotate around the rivets 12 in the installation plane of the mounting part 11, so as to adjust the axis of the hinge, so as to adapt to the axis of the lower hinge and eliminate the deviation of the coaxiality of the upper and lower hinges. Lubricant is required to reduce friction. like image 3 As shown, the rotating part 14 is a ...

Abstract

The invention discloses a car door hinge. The car door hinge comprises a fixed piece, a movable piece and a connecting piece, wherein the fixed piece and the movable piece are connected with each other through the connecting piece; the fixed piece comprises an installation part and a rotor; the installation part is installed on the car body structure; and the rotor is connected with the installation part through a rivet and can rotate on the installation plane of the installation part around the rivet, thereby adjusting the rotation axis of the hinge. The hinge of the invention can automatically adjust the coaxiality of the upper part and the lower part, overcome the bound force and effectively reduce the possibility of abnormal sound and vibration when the user opens or closes the car door. The hinge greatly reduces the closing force of the door and ensures that the car door can be easily opened and closed, thereby relieving the abrasion, prolonging the service life and saving the manufacturing cost.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to an auto door hinge. Background technique [0002] The general structure of the automobile door hinge is as follows: figure 1 As shown, it includes two parts, the movable leaf 2 and the fixed leaf 1, the movable leaf 2 is directly rigidly connected to the inner panel of the car door, and the fixed leaf 1 is directly rigidly connected to the body structure. The two-page connection is realized by fastening methods such as welding, riveting, and bolting. The movable leaf 2 is simply rotated relative to the fixed leaf 1, which is generally realized by pin shafts and corresponding bearing surfaces. In order to connect the door to the body, two hinges are usually used, the upper hinge and the lower hinge are divided into upper and lower arrangements, and are coaxially aligned by the pin shaft. In the actual production and assembly process, the installation of this hinge is often due to the ...
