Description

Automobile Door Hinges with Brake and Stop Functions

The present invention includes a first half hinge portion to be hooked onto a door device portion, a door or a door handle, a second half hinge portion attached to the other door mechanism portion, and both the half hinge portions An automobile door hinge consisting of hinge shafts connected to each other so as to swing each other, wherein the hinge shaft is made of a solid material, and at least one of the hinge eyes of the two half hinge parts has the hinge shaft. It is connected so as to be securely rotated between one hinge eye of the first half hinge portion or between both hinge eyes, and also to insert a shaft into one or two hinge eyes of the second half hinge portion. It relates to a car door hinge having a brake and a stop function configured to.

In order to obtain an integrated brake function and a stop function in the automobile door hinge, the hinge shaft is fixed to the hinge eye of the hinge portion of the first half hinge portion, and also passes through the hinge eye of the other half hinge portion having a progress tolerance. At least one wedge plate is formed so as to form at least a radially increasing wedge plate and a radially increased inner circumferential surface of the hinge eye boring of the hinge eye attached to the second half hinge portion. At this time, the both wedges are made as follows to have the same increase rate. In other words, both wedge boards are formed to form a pair of wedge boards arranged side by side in a plate shape over the entire covering area (DE-PS 44 06 824). Here, the wedge plate has one wedge plate which increases very flat on one side, and the other side has a side that descends to a steep slope, where the cost of manufacturing the hinge eye boring as well as the hinge axis is considerable. . In particular, the interlocking wedge boards have sufficient braking action on one side and early wear on the other side, and similarly to prevent harmful effects from environmental factors, one side on the hinge axis and the other on the inner peripheral surface of the hinge eye boring. This is because they must be manufactured with great precision. This is particularly important for applying to automobile doors, because the car doors carry a lot of weight on one side, and the other side receives high momentum, especially acceleration in the closing direction as it does when opening the door.

In another prior art, decisively above all other applications, namely in the construction technology of the hinges which are defined and usable as furniture hinges, in order to obtain an integral brake function and a stopping function, they are fixed to swing on the first half hinge and The hinge axis boring of the second half hinge part hinge wing of the same oval shape is mounted on the hinge axis having an elliptical lateral cross section beyond the length passing through the hinge eye of the second half hinge part of the device (DE-PS 44 06 824). The desired and required brake and stopping force here are mounted in the present prior art for the hinge using spring-elastic formation of the hinge eye of the second half hinge portion of which the inner circumferential surface is elliptical. The hinge eye then splits radially in the following manner. In other words, the hinge eye is composed of two arms that can wrap the hinge axis due to the spring tension, and can be relatively extended to each other, and the brake-stop force that can be best obtained inside the hinge is ultimately dependent on the spring action of the half hinge eyes. Installing the integrated device in such a manner as to have at least one constant door opening angle in order to obtain a brake-stopping force is absolutely inadequate for application to automotive doors. On the one hand, if one wants to obtain the maximum mountable brake-stopping force using the hinge structure as described above, it is completely insufficient to satisfy the weight and the kinetic energy. In addition, in other automobile door hinges, it may be difficult to radially open the hinge eyes of the second half hinge part because it is exposed to environmental effects, in particular the risk of contamination, and weather.

The above object of the present invention can be solved through the following. That is, the hinge shaft which is connected to the supplementary structure of at least one of the hinge boring (boring) of the hinge eyes formed in each half hinge portion is one of each of the one or each length area installed in the hinge eyes You can have at least one cross-sectional curving course that shrinks into a circular annulus through the part. In the nulling area of the outer circumferential surface of the head, which is usually neglected from the case, the hinge axis configured to have a pure cylindrical outer circumferential surface according to the present invention is continuous to its outer circumferential wall in the length region of the inaccurate cylinder type. We have a course to go to. In particular, the curving course of the hinge eye boring and the hinge axis transverse cross-section starting from the annulus lies in the dimension with the intended curvature error in accordance with the present invention. That is, the maximum deviation of the curved course having the annular shape is in the region corresponding to 1/100 to 1/10 of the general hinge axis diameter. Preferably, the radially projecting curvature deviation of the hinge axis, and thus the hinge eye boring, ranges between 1/100 and 1/10 of the normal hinge axis diameter. The continuous course of the hinge shaft outer circumferential surface offers the possibility of producing the hinge shaft and the hinge snow boring on the one hand in an inaccurate cylindrical length region on the one hand and on the other side as well. It is ensured that the internal resistance of the hinge to the opening operation of the door that exceeds the door opening angle described above continues to increase.

Therefore, in the configuration of the present invention, the hinge eye and the hinge boring are provided with only the cylinder type curved deviation which is formed on its outer circumferential surface and protrudes to the opposite side. In the door opening operation configuration according to the present invention, the door hinge of the automobile is configured to have a gradually increasing resistance to door opening that exceeds a predetermined opening angle. Thus, the hinge axis is provided with two annular deviations which are spaced apart from each other beyond its outer circumferential surface and radially protrude in opposite directions, in the form of an accurate annular cross section. At this time, the peaks of the two hinge shaft diameter deviations protruding from each other and having an annular shape are installed to face each other, and the hinge peaks are coupled to each other to have a 180 ° curvature between them.

Other details may be provided in addition to the conventional hinge configuration. In other words, the straight line that cuts the highest point of the hinge axis curved horseshoe which face each other and is radially projected is formed at a right angle of 90 ° with respect to the straight line that passes through the region of the stopper and the hinge nail.

In view of the fact that the braking of the door opening movements between the vehicle types may vary at each door opening angle, a stopper base of a hinge wing is formed by cutting a straight line that cuts the peaks of the hinge shaft curved horses facing each other radially. Can be adjusted at different angles of height. For each size of the freely allowed door opening angle, the peaks of both curved deviations of the radially projecting hinge shafts are accommodated so as to be within 180 ° of the outer curvature by being installed so that they can be controlled from each other at a predetermined angle without facing each other.

One embodiment of the configuration of the present invention has the following features. That is, the hinge axis has a curved deviation projecting one or two radially protruding from each other over its entire length, wherein the hinge axis uses a free-operating hinged eye boring, so that the hinge eyes of each half hinge part can swing It is secured internally and protected from being circumscribed around its longitudinal axis.

Most preferably, the hinge axis has at least one curved deviation projecting radially beyond a portion of the axial length of at least one hinge eye of each of the half hinge portions in a running fit configuration. At this time, the configuration of the hinge snow boring and installing the hinge together has the following advantages. That is, the axis length of the hinge axis with the radially projecting curvature deviation corresponds to at least 1/3 of the total axis length of the installed hinge eyes. Moreover, the hinge axis of the length part provided with the curvature deviation which radially protruded on both sides of the said one has an annular round cross-sectional shape.

In the longitudinal section of the hinge axis with at least one radially projecting curvature deviation, one axis is provided between the hinge axis and the hinge eye boring. This axis corresponds to half or less of the maximum radial protrusion of the curvature deviation. In particular, according to the present invention, the size of the shaft is made larger by increasing hinge axis diameter.

This preferred embodiment is configured as follows so that the hinge can be easily self-supporting without noise. That is, the hinge shaft is covered by its hinge eye and is beyond the length of the cylinder type course on its outer circumferential wall, by means of a bearing bushing made of safety bearing material, by means of a hinged eyeball boring in the form of a cylinder. It is mounted inside the unit. This has the advantage of a hinge arrangement that is absolutely easy to operate in addition to the full swing angle region, and in another aspect, the hinge shaft portion with at least one radially projecting curvature deviation to environmental factors has a complete Abschottung. To configure this secure hinge axis arrangement in a useful way, you can do the following: In other words, the wall thickness of the bearing bush is equal to or greater than the maximum value of the hinge shaft curvature deviation. According to the present invention, the shaft length must be configured such that the length corresponding to the bearing bushing configured as the yoke bushing is 1/4 or more of the maximum shaft length diameter so that the shaft can be safely disposed in the door opening angle. do.

In addition, an area of the length portion provided in the hinge shaft length portion having at least one radially protruding curved deviation is provided with an unbroken wall that wraps around the hinge eye which is supplemented to its hinge eye boring. The minimum thickness of the hinge eye wall corresponds to at least twice the hinge axis curvature deviation.

Another configuration of the present invention is configured as follows. That is, at least the hinge forms a wear protection film for its surface over its length with at least radially protruding curvature deviations, wherein the film comprises carbide, nitride, carbon nitride, and boron hard. Rigid membranes such as chrome plates, ceramic membranes, gradation and ion implanted membranes are used, or anti-wear coatings composed of solid lubricants such as MoS2, PTFE, Grafit, lead and cadmium.

In the first embodiment of the hinge portion configured as a detachable hinge, which has a gradually increasing resistance against opening of the automobile door beyond the predetermined door opening area, it can be configured as follows. That is, the hinge has a curved deviation projecting radially beyond a portion of the length area passing through the hinge eye of the first half hinge portion, and the accessory hinge eye is securely installed against the wall of the shaft, in which the safety device is one side It is formed as a radially projecting portion as a safety means that can be assembled on the other side, the hinge shaft is fixed to the inside of the hinge eye of the other half hinge portion using a chip means to rotate.

In the second embodiment of the hinge portion having a gradually increasing resistance to the opening of the automobile door beyond the predetermined door opening area can be configured as follows. That is, the hinge shaft is accommodated in both hinge eyes of the one half hinge portion that surrounds the center hinge eye of the other half hinge portion in a fork shape, and is also accommodated as an axis in the geared hinge eye of the other half hinge portion.

Lastly, the embodiments of the hinge portion mentioned later may be configured as follows to be usefully used.
