Description

Door lock mounting structure of plastic tail door

Technical Field

The utility model belongs to the technical field of the plastics tail-gate, a lock mounting structure of plastics tail-gate is related to.

Background

The automobile tail door lock is a device which can keep the tail door and the automobile body in a locking state and can be opened, and comprises a lock body, a lock catch and an operating mechanism. The tail door lock should satisfy the performance requirements of over-impact, durability in opening and closing, no disengagement at the full locking position under the inertial load and the like.

With the driving of light weight and personalized modeling of automobiles, the application of 'replacing steel with plastic' of the automobile tail gate is more and more, and the plastic tail gate on the market is generally formed by bonding an inner plate SMC material and an outer plate TPO material or bonding an inner plate PP + LGF material and an outer plate TPO material.

Because the characteristics of the inner plate material are poorer than the strength, the rigidity and the shock resistance of the metal material, the inner plate of the tail door is easy to break in the door lock area under the conditions of over-impact during the opening and closing of the tail door, inertial load and high-speed collision, and even the tail door body is completely separated from the door lock catch. (the requirements for the performance of the tail gate lock and the retainer under the inertial load are specified in the regulation GB 15086 requirements for the performance of the automobile door lock and the automobile door retainer and the test method).

The existing plastic tail door lock installation scheme is characterized in that a door lock is generally assembled on the inner side of a tail door inner plate, the door lock is assembled on the inner side of the inner plate, the door lock is assembled and disassembled after the inner plate and the outer plate of the tail door are bonded, the assembly and the disassembly maintenance need to pass through an assembly maintenance hole, the operation is inconvenient, the assembly maintenance hole needs to be additionally arranged in the inner plate door lock area, the local rigidity and strength are greatly reduced, and under the impact force received by the door lock, the inner plate is completely stressed at the installation point of the door lock, so that the inner plate is easily broken in the area.

Disclosure of Invention

The utility model aims to solve the technical problem, be to prior art's current situation, and provide a lock mounting structure of plastics tail-gate, very big assembly and the maintenance that has made things convenient for the lock, simultaneously also better promotion the regional rigidity and the shock resistance of tail-gate lock.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a lock mounting structure of plastics tail-gate, includes inner panel, planking and tail-gate lock, its characterized in that, inner panel and planking connect, the outside at the inner panel is installed to the tail-gate lock, the inner panel be provided with the metal reinforcing plate and with the tail-gate lock, the metal reinforcing plate carry out the spiro union through screw and self screw thread and inner panel.

In the door lock mounting structure of the plastic tail door, the metal reinforcing plate is provided with the riveting nut and the bolt, the riveting nut is riveted on the metal reinforcing plate, then the bolt is in threaded connection with the riveting nut on the metal reinforcing plate, and the tail door lock is assembled on the inner plate.

In foretell lock mounting structure of plastics tail-gate, the tail-gate lock on have the mounting panel, the mounting panel pass through the bolt and fixed with the inner panel, the outside laminating of mounting panel and inner panel, the laminating of metal reinforcing plate and inner panel.

Compared with the prior art, the utility model has the advantages of install the tail-gate lock in the inner panel outside, be convenient for assemble and dismantle, the inner panel inboard increases the metal reinforcing plate simultaneously and carries out the spiro union through the riveting nut with the tail-gate lock, and the inside and outside has all increaseed lifting surface area, and the improvement local rigidity and shock resistance all great on reaching outside two atress directions inwards.
