The lock body of the tailgate lock is generally installed on the tailgate lock reinforcement inside the tailgate sheet metal.

[0003] The existing tailgate lock reinforcement is relatively smooth as a whole, resulting in insufficient contact area between the reinforcement and the tailgate inner panel, resulting in poor installation stability. At the same time, due to the insufficient overall rigidity of the processing frame, the reinforcement is more likely to break at the connection when used for a long time or subjected to strong external force. Utility Model Content

[0004] The purpose of the utility model is to provide a tailgate lock reinforcement to solve the technical problems in the prior art that the reinforcement is relatively smooth as a whole, the contact area for installation is insufficient, the stability effect is poor, and the reinforcement is not rigid enough and is easily broken by external impact.

[0005] In order to achieve the above-mentioned purpose, a tailgate lock reinforcement is provided, including a middle plate portion: an installation groove is provided inside the middle plate portion, a rear outer flange is provided on one side of the middle plate portion, and the other side of the middle plate portion is connected to the front plate portion, a lock tongue through hole is provided on the side of the front plate portion close to the middle plate portion, and a lap sink is symmetrically provided on the other side of the front plate portion, a front outer flange is provided on the side of the front plate portion away from the middle plate portion, side outer flanges are provided at both ends of the middle plate portion and the front plate portion, and reinforcing ribs are provided on the top of the two groups of side outer flanges close to the side of the middle plate portion to facilitate improving the stability and rigidity of the overall installation of the reinforcement.

[0006] According to the tailgate lock reinforcement, a front glue groove and a rear glue groove are respectively provided on the side of the top of the two groups of side outer flanges away from the reinforcing ribs and the top of the two groups of reinforcing ribs, so as to facilitate the subsequent filling of adhesive.

[0007] According to the tailgate lock reinforcement, multiple groups are provided inside the middle plate portion and the front plate portion, so as to facilitate the later fixing and installation of the reinforcement.

[0008] According to the tailgate lock reinforcement, the two groups of reinforcement ribs are both made of a triangular structure, and a triangular through groove is provided inside the triangle. Since the triangle has stability, the overall rigidity of the reinforcement can be improved.

[0009] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention.

[0010] The purpose of the utility model is to provide a back door lock reinforcement member, the main innovations are:

[0011] Through the mutual cooperation of the rear outer flange, the overlapping sinker, the side outer flange and the front outer flange, the overall contact area of ​​the reinforcement can be effectively increased. Compared with the overall smoothness of the existing reinforcement, the stability effect of later fixation can be effectively improved. Through the structural design and shape of the reinforcement ribs, the rigidity of the reinforcement can be effectively improved, the fracture phenomenon caused by later external force impact can be reduced, and its service life can be effectively extended.
