[0024] Please refer to Figure 1, an installation structure of a door limiter provided by the present utility model includes a limiter 10 and a door reinforcement plate 20. The limiter 10 includes a limiter main body 11 and a limit arm 12. A fixing structure 30 and a positioning structure 40 are provided between the limiter main body 11 and the door reinforcement plate 20. The limiter main body 11 is fixed to the door reinforcement plate 20 through the fixing structure 30 and the positioning structure 40 and can move with the door. The limiter 10 is installed between the vehicle body and the door. One end of the limit arm 12 passes through the limiter main body 11 and the door reinforcement plate 20 and is connected to the vehicle body. The other end of the limit arm 12 is located inside the door and cannot be disengaged from the limiter main body 11. Compared with the prior art, the fixing structure 30 in the present utility model can avoid the problem that the fixing bolts and fixing nuts are simultaneously exposed, which affects the aesthetics of the vehicle, and the positioning structure 40 can realize the rapid positioning of the limiter 10 and improve the assembly efficiency of the limiter 10.
[0025] Please refer to Figure 2 and Figure 3 , the limiter main body 11 includes a limiter housing 111, and a slider 13, a spring 14 and a baffle 15 installed inside the limiter housing 111. In this embodiment, the number of the slider 13, the spring 14 and the baffle 15 is two. It can be understood that the number of the slider 13, the spring 14 and the baffle 15 is not limited to this, and the number can also be more than two. The slider 13 is arranged on two opposite sides of the limit arm 12. The limit arm 12 passes through the space between the sliders 13 and can slide relative to the slider 13. The spring 14 is arranged inside the slider 13. One side of the baffle 15 facing away from the spring 14 is fixedly connected to the limiter housing 111. A card slot (not shown in the figure) is provided on the side of the baffle 15 facing the spring 14. One end of the spring 14 abuts against the inside of the slider 13, and the other end is clamped into the card slot on the baffle 15 to prevent the spring 15 from generating displacement as the limit arm 12 slides. One end of the limit arm 12 is provided with a mounting bracket 16. The mounting bracket 16 and the corresponding end of the limit arm 12 are hinged through a pin shaft, that is, the limit arm 12 can rotate relative to the mounting bracket 16. The mounting bracket 16 is provided with a mounting hole. The mounting bracket 16 is fixed to the vehicle body through the cooperation of a fastener and the mounting hole. The other end of the limit arm 12 is provided with a stop baffle 17. The stop baffle 17 is located inside the door and can prevent the limit arm 12 from being disengaged from the limiter main body 11. Further, a plurality of depressions 121 arranged along the length direction of the limit arm 12 are provided on the surface of the limit arm 12 opposite to the slider 13. When the limiter main body 11 moves relative to the limit arm 12 following the door, the slider 13 can be clamped into the corresponding depression 121 under the elastic force of the spring 14, so that the door can be stationary at different opening degrees. It should be noted that for other structures of the limiter 10, reference can be made to the prior art and will not be elaborated here.
[0026] Please refer to Figure 2 , Figure 4 andFigure 5 The fixing structure 30 includes a fixing nut 31 and a fixing bolt 32. The fixing nut 31 is arranged inside the limiter housing 111. A part of the fixing bolt 32 can pass through the limiter housing 111 and the door reinforcement plate 20 and be connected to the fixing nut 31. It should be noted that the limiter housing 111 is made of plastic. The fixing nut 31 is embedded in the limiter housing 111 and injection-molded with the limiter housing 111, and an installation cavity covering the fixing nut 31 is formed inside the limiter housing 111. It should be noted that the limiter housing 111 can also be made of metal or other materials and be integrally connected with the fixing nut 31. For example, when the limiter housing 111 is made of metal, the fixing nut 31 can be integrally connected with the limiter housing 111 by welding.
[0027] Specifically, the fixing nut 31 includes a disc-shaped part 311 and a columnar part 312. A threaded hole for cooperating with the fixing bolt 32 is provided inside the columnar part 312. The disc-shaped part 311 is arranged at the top of the columnar part 312. A through hole corresponding to the threaded hole is provided on the disc-shaped part 311 to facilitate the fixing bolt 32 to pass through. The disc-shaped part 311 and the columnar part 312 are embedded in the installation cavity and injection-molded with the limiter housing 111. The fixing bolt 32 includes a nut 321 and a stud 322. The nut 321 is arranged at the top of the stud 322. The stud 322 sequentially passes through the door reinforcement plate 20 and the through hole on the disc-shaped part 311 and is screwed into the threaded hole on the columnar part 312 to fix the limiter housing 111 to the door reinforcement plate 20. Therefore, after installation, only the nut 321 of the fixing bolt 32 can be seen from the door reinforcement plate 20. Compared with the prior art, the problem that the fixing bolt 32 and the fixing nut 31 are exposed at the same time, which affects the overall aesthetics of the vehicle, can be avoided.
[0028] Furthermore, as Figure 2 and Figure 4 shown, the limiter housing 111 can be pre-positioned on the door reinforcement plate 20 through the positioning structure 40. The positioning structure 40 includes a mutually cooperating positioning flange 41 and a positioning groove 42. One of the positioning groove 42 and the positioning flange 41 is arranged on the limiter housing 111, and the other of the positioning groove 42 and the positioning flange 41 is arranged on the door reinforcement plate 20. In the present utility model, the positioning flange 41 is arranged on the door reinforcement plate 20, and the positioning groove 42 is arranged on the limiter housing 111. The limiter housing 111 is positioned on the door reinforcement plate 20 through the cooperation of the positioning flange 41 and the positioning groove 42, and is fixedly connected to the door reinforcement plate 20 through the cooperation of the fixing nut 31 and the fixing bolt 32 after positioning. Since the installation of the limiter housing 111 and the door reinforcement plate 20 is first positioned through the cooperation of the positioning flange 41 and the positioning groove 42, so that the fixing bolt 32 can quickly align with the fixing nut 31, therefore, the quick positioning of the limiter 10 can be realized, and the assembly efficiency of the limiter 10 is improved.
[0029] Please refer to Figure 4 , the door reinforcement plate 20 is fixed on the door, which can improve the installation strength of the installation position of the upper limiter 10 on the door. A through groove 21 for the mounting bracket 16 on the limiting arm 12 to pass through is provided on the door reinforcement plate 20, and the through groove 21 is integrally rectangular in structure. Mounting holes 22 for facilitating the installation of the fixing bolts 32 are symmetrically provided on both sides of the through groove 21. The positioning flange 41 is arranged on the edge of the through groove 21 close to the mounting hole 22, and the positioning flange 41 extends perpendicularly from the edge of the through groove 21 towards the direction close to the limiter housing 111. There are two edges of the through groove 21 close to the mounting hole 22, and the positioning flange 41 can be arranged on any one of the two edges, and the positioning function can be realized.
[0030] Please refer to again Figure 2 , the positioning groove 42 and the fixing nut 31 are arranged on the limiter housing 111 along the length direction of the limiter housing 111 in alignment, and the positioning groove 42 is arranged on the limiter housing 111 at a position close to the limiting arm 12, and the fixing nut 31 is symmetrically embedded in the limiter housing 11 at a position far from the limiting arm 12. That is, the position of the positioning groove 42 corresponds to the position of the positioning flange 41 on the door reinforcement plate 20, and the position of the fixing nut 31 corresponds to the position of the mounting hole 11 on the door reinforcement plate 20. In addition, an alignment surface 421 is provided in the positioning groove 42, and the alignment surface 421 is located on the side of the positioning groove 42 close to the limiting arm 12. The alignment surface 421 is parallel to the positioning flange 41 and has a comparable width. In this way, during positioning, as long as the positioning flange 41 is moved to fit with the alignment surface 421, it indicates that the mounting hole 22 on the door reinforcement plate 20 is aligned with the fixing nut 31 on the limiter housing 111. Thus, the rapid positioning of the limiter 10 can be realized, and the assembly efficiency of the limiter 10 is improved. In addition, the depth of the positioning groove 42 is equal to the length of the positioning flange 41, which also plays a supporting role for the door reinforcement plate 20 and facilitates the installation of the fixing bolts 32 and the fixing nuts 31.
[0031] Furthermore, a docking structure (not shown in the figure) is provided between the alignment surface 421 and the positioning flange 41. The docking structure includes a docking convex block and a docking groove. One of the docking convex block and the docking groove is arranged on the alignment surface 421, and the other of the docking convex block and the docking groove is arranged on the positioning flange 41. In the present utility model, the docking groove can be arranged on the alignment surface 421, the docking groove is recessed towards the limiting arm 12 relative to the alignment surface 421, the docking convex block is arranged on the positioning flange 41, and the docking convex block protrudes on the surface of the positioning flange 41 facing the docking groove. During positioning, through the clamping of the docking groove and the docking convex block, it can be determined that the positioning flange 41 fits with the docking surface 421, indicating that the mounting hole 22 on the door reinforcement plate 20 is aligned with the fixing nut 31 on the limiter housing 111, which can further improve the positioning accuracy.
[0032] As can be known from the above description, for the installation structure of a car door limiter provided by the present utility model, by embedding the fixing nut 31 in the limiter housing 111, and through the cooperation of the fixing bolt 32 and the fixing nut 31, the limiter housing 111 is fixed on the door reinforcement plate 20. Moreover, after the limiter housing 111 is fixed, only the nut 321 of the fixing bolt 32 is exposed on the door reinforcement plate 20. Compared with the prior art, it can avoid the problem that the fixing bolt and the fixing nut are both exposed, which affects the aesthetics of the vehicle. The present utility model realizes the quick positioning of the limiter 10 and improves the assembly efficiency of the limiter 10 by setting the positioning structure 40, and setting the positioning flange 41 in the positioning structure 40 on one of the door reinforcement plate 20 and the limiter housing 111, and setting the positioning groove 42 on the other of the door reinforcement plate 20 and the limiter housing 111, and through the cooperation of the positioning flange 41 and the positioning groove 42.
