Description

Vehicle door hinge with supporting, limiting and bearing functions

Technical Field

The invention relates to the technical field of van-type special automobiles, in particular to a door hinge with supporting, limiting and bearing functions.

Background

Hinges are mechanical devices used for connecting two solid bodies and allowing relative rotation between the two solid bodies, and the hinges are also necessary devices of van-type automobiles. The doors of van vehicles are generally classified into two types, one is an upturned door, and the other is a downturned door. For the situation that the upward-turning type car door does not need to bear the weight after being opened, a cylinder type supporting mechanism is often matched with a conventional external hinge to be turned upward and opened; for the downward-turning type vehicle door, after the vehicle door is rotated, unfolded and laid flat, the vehicle door is often required to be used as a load-bearing device such as a step, a support operation platform and the like. Ordinary upset hinge or fold paper and only possess the rotation function, do not possess and support limit function, in order to realize the spacing support of formula door of turning down, adopt following various techniques more among the prior art:

1) the support limit of the downward-turning type vehicle door is realized by matching a common external turning hinge without a limit function with a support rod, wherein the support rod is additionally arranged at the lower end of the vehicle door, and the vehicle door is supported and limited by the support rod at the lower end of the vehicle door after the vehicle door is rotated and leveled; however, this method requires additional design of the support bar or the zipper, which increases the design cost and is inconvenient to use, and also requires additional space.

2) The hydraulic cylinder arranged on the vehicle door is used for realizing the turnover opening of the vehicle door, and the method can realize the limiting and supporting effect of the vehicle door by utilizing the self locking force of the hydraulic cylinder; but the shortcoming is that the hydraulic cylinder and the hydraulic system are required to be added for control, the cost is increased, and the space in the carriage is additionally occupied.

3) Chinese patent with publication number CN205502817U also discloses a hinge mechanism with a limiting function, which comprises a main hinge, an auxiliary hinge, a hinge pin shaft and a limiting bracket assembly, wherein the main hinge and the auxiliary hinge are connected through the hinge pin shaft, and the hinge pin shaft and the main hinge are welded and fixed; the limiting bracket assembly is arranged above the main hinge and the auxiliary hinge, one end of the limiting bracket assembly is fixedly connected with the main hinge, and the other end of the limiting bracket assembly is connected with the auxiliary hinge; the secondary hinge can slide along the limit bracket assembly and can be positioned. However, the overturning limiting of the hinge mechanism is mainly realized by a limiting plate with a groove, the mechanical strength is low, and the use requirements of large-weight components such as steps and operation platforms cannot be met.

Detailed Description

The technical solution of the present invention is explained in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 4, a vehicle door hinge with supporting, limiting and bearing functions comprises a rotating plate 2 and two collision blocks 1, wherein each vehicle door 5 is provided with two groups of rotating plates 2 and two groups of collision blocks 1, the two groups of collision blocks 1 are respectively fixed on the inner sides of a left door frame and a right door frame of a door frame framework 4, the rotating plate 2 is an L-shaped bent plate, one folded plate of the L-shaped bent plate is fixed on two sides of the door plate 5, the other folded plate of the L-shaped bent plate extends towards the collision block 1 to form a space structure surrounding the collision block 1, one side of the L-shaped bent plate, which is close to the collision block 1, is provided with a hinge shaft 21, and the collision block 1 is provided with a hinge hole 11 in hinge fit with the hinge shaft 21; the door plant of door 5 is including supporting door plant 51 and spacing door plant 52, and wherein, the width that supports door plant 51 is less than the width of spacing door plant 52, and the width of spacing door plant 52 is greater than both sides and hits the distance between 1 opposite faces, and the width that supports door plant 51 is less than both sides and hits the distance between 1 opposite faces, the shape of hitting piece 1 is according to the design of the spacing angle of door 5.

The supporting door plate 51 is hinged between the two collision blocks 1, the limiting door plate 52 is arranged on one surface of the supporting door plate 51 and forms a step surface with the supporting door plate 51, and the step surface of the limiting door plate 52 is matched with the bottom surface of the collision block 1 through surface contact to form a limiting structure of the vehicle door 5.

Optionally, the support door panel 51 and the check door panel 52 are integrally formed to improve the reliability of the vehicle door 5 as a load-bearing member.

In this embodiment, the collision block 1 is rectangular, so the door panel 5 is turned downward until the limiting door panel 52 abuts against the bottom of the collision block 1, and the door panel 5 stops turning, and the maximum turning angle of the door panel 5 is 90 °.
