Description

Automobile hinge mounting reinforcing plate

Technical Field

The utility model relates to an automobile body structure field, concretely relates to car hinge mount reinforcing plate.

Background

Hatchback or SUV models are very popular at present, and the back tail door of the vehicle is connected with the upper edge of the door frame on the back wall of the vehicle body through a hinge, so that the lifting type opening mode of the tail door is realized.

The difficulty of designing the reinforcing plate for installing the tail gate hinge of the two-compartment vehicle or the 6 or 7-seat SUV vehicle is obviously increased due to the close proximity of the head of the third row passenger and the upper part of the tail gate. The design difficulty is shown in a centralized way: 1) In arrangement, the position of the back-surrounding hinge is limited by the shape and the head space of a human body; 2) In structural design, the back door of the automobile conducts force to the automobile body part through the hinge when the back door of the automobile is opened and closed, if rigidity of an installation point of the hinge of the automobile body is too poor, the automobile body can generate overlarge deformation, the use performance of the back door is further influenced, potential safety hazards exist, and therefore serious safety accidents can be caused.

The name is 'a novel automobile tail door hinge mounting structure' (CN 211900181U), which comprises an automobile tail door 1, a tail door hinge 2, an automobile body 3 and a tail door hinge reinforcing plate 4, wherein two sides of the tail door hinge reinforcing plate 4 are respectively provided with a welding nut 9, the tail door hinge reinforcing plate 4 is fixedly mounted at the bottom of a tail door hinge mounting plate 6 by driving a fastening bolt 7 into the welding nuts 9, and the fastening bolt 7 penetrates through the automobile body 3 and is driven into the welding nuts 9; two tail door hinge positioning holes 10 are formed in the top of the tail door hinge reinforcing plate 4, two mounting bolts 11 matched with the tail door hinge positioning holes 10 are arranged on the tail door hinge 2, and the tail door hinge 2 is mounted on the automobile body 3 by driving mounting nuts 12 into the mounting bolts 11. In the above scheme, tail-gate hinge reinforcing plate 4 is through the welded nut 9 and the fastening bolt 7 cooperation of both sides with its fixed mounting in tail-gate hinge mounting panel 6's bottom, adopts bolted connection mode to connect tail-gate hinge reinforcing plate 4 and tail-gate hinge mounting panel 6, because the vibration of vehicle driving in-process can not be avoided, its installation fixed reliability is difficult to guarantee, so this scheme has still set up the access hole so that observe tail-gate hinge reinforcing plate 4's state, and this has further reduced tail-gate hinge mounting's bulk strength.

The name of the tail door hinge reinforcing plate (CN 101476421A) comprises a plane plate 1 and welding edges 4 arranged on the plane plate 1, wherein the plane plate 1 is provided with an installation channel 3 for installing the tail door hinge, and the three welding edges are arranged on the periphery of the plane plate 1 and connected by a transition surface. Three welding edges 12, 13 and 14 are respectively welded with the inner plate of the top cover rear cross beam, and then the reinforcing plate and the top cover rear cross beam are welded with the outer plate of the top cover rear cross beam. The connection mode can not ensure the supporting and reinforcing effect of the reinforcing plate on the outer plate of the top cover rear cross beam, and the position stability of the plane plate 1 can not be ensured.

Detailed Description

With reference to fig. 1, 2 and 3, the reinforcing plate for mounting the hinge of the automobile, the reinforcing plate 10 includes an upper top plate 11, and the upper top plate 11 is provided with a connecting hole 111 for mounting the hinge, which is characterized in that: the edge of the upper top plate 11 is provided with left, right, front and rear side walls 12, 13, 14 and 15 which extend downwards, the left, right and front side walls 12, 13 and 14 are connected with a lower connecting plate on the vehicle body in a welding way, and the upper top plate 11 and the rear side wall 15 are connected with an upper connecting plate on the vehicle body in a welding way.

In the above scheme, not only the left and right side walls 12, 13, 14 and the lower connecting plate welded connection on the automobile body, but also the upper top plate 11 and the rear side wall 15 and the upper connecting plate welded connection on the automobile body are welded, the above connection scheme ensures that the periphery of the upper top plate 11 is supported and fixed, the scheme of less stable fixation of three-side constraint and unilateral freedom of the upper top plate 11 in the prior art is avoided, thereby ensuring the stability of the upper top plate 11 and naturally improving the strength of the hinge installation part.

For convenience of understanding, the front and rear directions are the same direction of the front and rear of the vehicle, that is, the front of the vehicle head is the front of the vehicle, the rear of the vehicle is the rear of the vehicle, and the left and right positions are left and right positions in a state that the vehicle faces the front of the vehicle.

Preferably, the lower edges of the left, right and front side walls 12, 13 and 14 are provided with external flanges 121, 131 and 141 which are welded with the lower connecting plate 1 on the vehicle body, and the rear side wall 15 is welded with the upper connecting plate 2 on the vehicle body in a fitting manner, wherein the inclination of the corresponding position of the rear side wall is matched with that of the upper connecting plate. In the above scheme, the rear side wall 15 is welded to the rear inclined surface of the upper connecting plate 2 on the vehicle body, so that the stability of the upper top plate 11 can be further enhanced, and meanwhile, the bending part 2a at the rear part of the upper connecting plate 2 is assisted to be enhanced, namely, the left and right side walls 12 and 13 on the two sides play a role in supporting and restraining the upper and lower directions of the inclined surface part of the upper connecting plate 2.

Smooth curved surface transition is formed among the left side wall, the right side wall, the front side wall and the rear side wall 12, 13, 14 and 15, and smooth curved surface transition is formed among the upper top plate 11, the left side wall, the right side wall, the front side wall and the rear side wall 12, 13, 14 and 15. This can prevent the occurrence of stress concentration and improve the strength of the reinforcing plate 10 itself.

The lower edge of the rear side wall 15 is higher than the lower edges of the left, right and front side walls 12, 13 and 14 beside the rear side wall. Preferably, the vertical dimension of the rear side wall 15 is 1/2 of the vertical dimension of the left, right and front side walls 12, 13, 14. According to the scheme, the stability of the upper top plate 11 is guaranteed, meanwhile, the requirement of improving the supporting strength is met due to the fact that the connecting area of the inclined plane part of the corresponding position of the upper connecting plate 2 is enough, the effects of simplification and light weight structural design are achieved, and meanwhile the supporting effect of the left side wall 12, the right side wall 13, the front side wall 14 and the rear side wall 15 is guaranteed.

As shown in fig. 1, the two ends of the rear sidewall 15 are smoothly transited to the rear sides of the left and right sidewalls 12, 13. This avoids stress concentration at the junction of the two ends of the rear side wall 15 and the left and right side walls 12, 13.

With reference to the drawings, the reinforcing plate 10 is integrally in a box-shell shape with a large lower opening area and a small top area, and the included angles β between the left, right, front and rear side walls 12, 13, 14 and 15 and the surfaces of the flanges 121, 121 and 141 are 45 to 80 degrees, preferably 70 to 80 degrees. It should be noted that the included angle is an included angle swept by the left, right, front and rear side walls 12, 13, 14, 15 when the surfaces of the flanges 121, 141 are reversed, wherein the included angle between the rear side wall 12, 13, 14, 15 and the flanges may be smaller than the included angles seen by the other side walls to match the slope of the rear slope of the upper connecting plate 2.
