Detailed Description
The utility model will be further described with reference to the accompanying drawings in which:
with reference to the accompanying drawings: the hinge reinforcing plate applied to the back door of the automobile comprises a reinforcing plate body 1, wherein the reinforcing plate body 1 is divided into an A part 11, a B part 12 and a C part 13 according to different installation positions, the A part 11 and the B part 12 are of a configuration with concave middle parts, a plurality of first installation holes 3 are formed in the lower concave parts of the A part 11 and the B part 12 and the upper surface of the C part 13 and used for installing the reinforcing plate body 1 on the back door inner plate, and the C part 13 is provided with a lightening hole 13-a. In the assembly, the user can realize installing the hinge reinforcing plate in back of the body door inner panel fast through first mounting hole 3, and the connection stability who brings after screwing through the fastener, also convenient to detach in later maintenance simultaneously, compare in welded mode later maintenance cost lower, the hinge reinforcing plate of this structure has obvious the reduction in weight simultaneously, because its A portion 11 structure is two kinds of structures with C portion 13 structure, it is stronger to compare in the equal style of current product plasticity, and when satisfying the requirement that the hinge reinforcing plate can stable installation in back of the body door inner panel, through doing lightening hole 13-a at C portion 13 and lightening the weight of hinge reinforcing plate.
In order to avoid interference caused by the fasteners after screwing in the backdoor outer plates, each first mounting hole 3 is provided with a notch 4 in the A part 11 or the B part 12 or the C part 13, the notches 4 can be used for embedding the fasteners, the upper ends of the fasteners are not higher than the bottom surface of the A part 11 or the B part 12 and the upper surface of the C part 13, the upper ends of the fasteners are not exposed outside after the fasteners are installed through the notches 4, and therefore when the backdoor outer plates are covered, the upper ends of the fasteners cannot abut against the inner wall of the backdoor outer plates, the sealing performance of the backdoor outer plates and the backdoor inner plates after being spliced is good, and no fit clearance exists.
Further perfection, the hole distribution spacing between two adjacent first mounting holes 3 is less than or equal to 220mm, and reasonable hole spacing can make the stress of every department of hinge reinforcing plate or every section distance all be even, like this with hinge reinforcing plate complete fixation in back of the body door inner panel after, the hinge reinforcing plate can not be because of some regional bearing poor and lead to the fact by the condition emergence of bow.
Considering that the rigidity of the C portion 13 may be reduced after the lightening hole 13-a is formed, the C portion 13 further has a plurality of first reinforcing ribs 5 arranged around the lightening hole 13-a, each first reinforcing rib 5 is located between two adjacent first mounting holes 3 at the C portion 13, the thickness of the hole edge is increased by adding the first reinforcing rib 5 around the lightening hole 13-a, and the rigidity around the lightening hole 13-a is correspondingly increased after the thickness is increased, so that when the C portion 13 is mounted on the back door inner panel through the fastening member, the deformation force caused by the fastening member pressing the C portion 13 after fastening can be resisted, and the situation that the C portion 13 is arched is effectively avoided.
In order to improve that the hinge reinforcing plate can be in more contact with the back door inner plate after being embedded into the back door inner plate, the outer edges of the A part 11 and the B part 12 are provided with the bending parts 2 arranged along the track of the outer edge, because the hinge reinforcing plate is embedded, the first reinforced part of the hinge reinforcing plate is the position where the groove is formed in the back door inner plate, but the effect of rigidity increase brought to the back door inner plate is only single, so the bending parts 2 are arranged at the outer edges of the A part 11 and the B part 12, the contact area between the hinge reinforcing plate and the back door inner plate can be increased by utilizing the bending parts 2, the increase of the contact area also means that the original N in the back door is changed into the thickness of N +1, so the rigidity of the back door is naturally improved, and the rigidity of the back door is also improved.
Further perfect, the portion of bending 2 still has second mounting hole 21, and the fixed restraint to the hinge reinforcing plate not only embodies in itself, also does fixed restraint to portion of bending 2 through set up second mounting hole 21 in portion of bending 2 to make portion of bending 2 can realize stable connection with the back of the body door inner panel, keeps the rigidity of the back of the body door after the reinforcing.
Further perfect, the lateral part of second mounting hole 21 has second strengthening rib 6, and second strengthening rib 6 is used for thickening the junction at the outer border of portion 2 and A portion 11 of bending, and the principle that sets up of second strengthening rib 6 here is the same with the principle of first strengthening rib 5, also is in order to resist the fastener behind the fastening to the bending portion 2 causes the warp power that the oppression brought to the condition emergence of bowing effectively avoids bending portion 2 to appear.
Further perfect, A portion 11, B portion 12, the interior border of C portion 13 upwards rolls up and highly is higher than the portion of bending 2, it is in door glass department to consider that the mounted position of hinge reinforcing plate on the back of the body door inner panel, the structure of so this department is in order to facilitate door glass's installation, the circular arc transition that upwards extends has, the installation of the glass of not only being convenient for like this, also have good limiting displacement to the hinge reinforcing plate, the interior border upwards rolls up can increase the matching degree of hinge reinforcing plate and back of the body door inner panel, thereby it is better to make the hinge reinforcing plate exist in the installation of back of the body door inner panel, just also mean in the back of the body door by original N into plate thickness N +1 simultaneously, so in nature promote its rigidity, also make the rigidity of back of the body door better.
While the utility model has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
