One end of the support plate 103 is fixedly connected to an upper fixed plate support 101. Reinforcement plates 102 for improving strength are fixedly connected to both sides of the upper fixed plate support 101. One end of the support plate 103 away from the upper fixed plate support 101 is fixedly connected to a positioning buckle plate 105. A right fixing hole 108 is opened on the upper surface of the support plate 103 on one side of the positioning buckle plate 105. A left fixing hole 107 is opened on the side of the positioning buckle plate 105 away from the right fixing hole 108. A right buckle plate 106 is fixedly connected to the support plate 103 below the right fixing hole 108. A left buckle plate 104 is fixedly connected to the support plate 103 below the left fixing hole 107.

[0025] In this way, the overall strength of the back door lock reinforcement plate is enhanced by the reinforcement plates 102 fixed on both sides of the support plate 103. The upper fixing plate support plate 101 fixed between the reinforcement plates 102 provides greater support force for the back door lock reinforcement plate. The right buckle plate 106, left buckle plate 104 and positioning buckle plate 105 fixedly connected at one end far from the upper fixing plate support plate 101 provide multiple buckle positions for the back door lock reinforcement plate. Through these multiple buckle positions, the connection between the back door lock reinforcement plate and related components is made more firm, enabling it to better withstand various external forces and reducing the risk of loosening and displacement. The right fixing hole 108 and left fixing hole 107 opened on the surface of the support plate 103 can accurately and firmly install the back door lock reinforcement plate in the corresponding position, ensuring its reinforcement effect.

[0026] As an alternative embodiment, as Figure 3 , Figure 4 shown, a fixed quick-release assembly 2 is fixedly installed on the right fixing hole 108 and left fixing hole 107. The fixed quick-release assembly 2 is provided with a fixed outer sleeve 202. The fixed outer sleeve 202 passes through the support plate 103 through the right fixing hole 108. One end of the fixed outer sleeve 202 is provided with an outer thread 207, and a nut 201 is threadedly connected to the outer thread 207. The nut 201 acts on the upper surface of the support plate 103. The other end of the fixed outer sleeve 202 is provided with a plurality of uniformly distributed support buckle receiving grooves 208. A support buckle 203 is rotatably connected to the support buckle receiving grooves 208. A spring 210 is fixedly connected between the support buckle 203 and the fixed outer sleeve 202. A tension rod 205 is slidably connected inside the fixed outer sleeve 202. One end of the tension rod 205 is fixedly connected with a fixed support rod 206. The fixed support rod 206 is fixedly connected with the support buckle 203 for pushing and fixing the support buckle 203. The end of the tension rod 205 far from the fixed support rod 206 is fixedly connected with a threaded rod 209. A dovetail nut 204 is threadedly connected to the threaded rod 209. The dovetail nut 204 abuts against one end of the fixed outer sleeve 202.

[0027] In this way, the tension rod 205 is pushed to further pull the support buckle 203 into the support buckle storage groove 208, making its outer diameter smaller than the fixing hole, facilitating the insertion of the fixed outer sleeve 202 into the fixing hole. After inserting the fixed outer sleeve 202 into the fixing hole, the tension rod 205 is released. Under the elastic force of the spring 210, the support buckle 203 is pushed outwards. After the support buckle 203 expands, its diameter is larger than the fixing hole. After tightening the fixed outer sleeve 202, the support buckle 203 will be fixed at the bottom of the back door lock reinforcement plate. By rotating the dovetail nut 204, the fixed support rod 206 acts on the support buckle 203 under the support force of the fixed outer sleeve 202 to completely fix it. Then, according to the thickness of the back door lock reinforcement plate and the fixed position, the screw pitch of the nut 201 on the fixed outer sleeve 202 is adjusted. When disassembling, only the nut 201 and the dovetail nut 204 need to be loosened, and the tension rod 205 is pushed to make the support buckle 203 retract into the support buckle storage groove 208, making its outer diameter smaller than the hole diameter, so that the back door lock reinforcement plate can be disassembled simply and quickly without the problem of inconvenient disassembly and assembly due to small space.

[0028] In this embodiment, the overall strength of the back door lock reinforcement plate is enhanced by the reinforcement plates 102 fixed on both sides of the support plate 103. The upper fixing plate support plate 101 fixed between the reinforcement plates 102 provides greater support force for the back door lock reinforcement plate. The right buckle plate 106, the left buckle plate 104, and the positioning buckle plate 105 fixedly connected at one end far from the upper fixing plate support plate 101 provide multiple buckling positions for the back door lock reinforcement plate. Through the multiple buckling positions, the connection between the back door lock reinforcement plate and related components is made more firm, enabling it to better withstand various external forces and reducing the risk of loosening and displacement. The right fixing hole 108 and the left fixing hole 107 opened on the surface of the support plate 103 can enable the back door lock reinforcement plate to be accurately and firmly installed in the corresponding position, ensuring its strengthening effect. By pushing the tension rod 205 to further pull the support buckle 203 into the support buckle storage groove 208, making its outer diameter smaller than the fixing hole, facilitating the insertion of the fixed outer sleeve 202 into the fixing hole. After inserting the fixed outer sleeve 202 into the fixing hole, the tension rod 205 is released. Under the elastic force of the spring 210, the support buckle 203 is pushed outwards. After the support buckle 203 expands, its diameter is larger than the fixing hole. After tightening the fixed outer sleeve 202, the support buckle 203 will be fixed at the bottom of the back door lock reinforcement plate. By rotating the dovetail nut 204, the fixed support rod 206 acts on the support buckle 203 under the support force of the fixed outer sleeve 202 to completely fix it. Then, according to the thickness of the back door lock reinforcement plate and the fixed position, the screw pitch of the nut 201 on the fixed outer sleeve 202 is adjusted. When disassembling, only the nut 201 and the dovetail nut 204 need to be loosened, and the tension rod 205 is pushed to make the support buckle 203 retract into the support buckle storage groove 208, making its outer diameter smaller than the hole diameter, so that the back door lock reinforcement plate can be disassembled simply and quickly without the problem of inconvenient disassembly and assembly due to small space.
