Description
Technical Field
[0001] This utility model relates to the technical field of segmented hinge reinforcement plates, specifically a segmented hinge reinforcement plate with a positioning structure that facilitates welding and installation. Background Technology
[0002] Door hinge reinforcement plates are key structural components of automobile doors, used to enhance the rigidity and strength of hinge mounting points and prevent sagging, deformation, or cracking caused by long-term use or impacts. Traditional one-piece hinge reinforcement plates suffer from problems such as heavy weight, numerous welding points, and high maintenance costs. In recent years, split designs have gradually become mainstream. By dividing the reinforcement plate into three parts—upper hinge reinforcement plate, limiter reinforcement plate, and lower hinge reinforcement plate—optimization is made for the stress characteristics of different areas, achieving weight reduction (approximately 50%) and a reduction in the number of welding points (approximately 1 / 3), while also reducing maintenance difficulty.
[0003] However, the split design revealed new problems during maintenance: the welding position of the upper and lower hinge reinforcement plates on the inner panel of the door directly affects the installation position of the upper and lower hinges. When welding and fixing, if there is a slight deviation between the welding position of a certain reinforcement plate (such as the upper or lower hinge reinforcement plate) and the inner panel of the door, the relative position of the two hinges may shift. This can lead to the inability to accurately install the upper and lower hinges smoothly when the door and frame are installed through the hinges. Even if forced to install, the axis of the upper and lower hinges may be misaligned, causing interference during opening and closing and affecting the normal opening and closing of the door.
[0004] In the existing technology, although some solutions use positioning holes or protrusions to assist welding positioning (such as the guide protrusions of the door panel and the reinforcing plate), these methods are only applicable when the positioning holes on the reinforcing plate and the door panel are precisely aligned and the positioning holes of the upper and lower hinges are precisely matched. If any of these deviations occur, it may lead to misalignment of the upper and lower hinges. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a segmented hinge reinforcement plate with a positioning structure that facilitates welding and installation, enabling precise positioning during hinge reinforcement plate welding.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a segmented hinge reinforcement plate with a positioning structure for easy welding and installation, comprising an upper hinge reinforcement plate and a lower hinge reinforcement plate installed on the inner panel of a car door, with two support components connecting the upper and lower hinge reinforcement plates, and several snap-fit holes penetrating through the side walls of both the upper and lower hinge reinforcement plates, the snap-fit holes of the upper and lower hinge reinforcement plates being symmetrically arranged, and snap-fit components connected to both ends of the support components, the snap-fit components being connected to the snap-fit holes.
[0007] Furthermore, the snap-fit assembly includes a snap-fit block and a snap-fit piece. The snap-fit block is connected to one end of the support assembly, and the other end of the snap-fit block passes through a snap-fit hole and is fixedly connected to the snap-fit piece.
[0008] Furthermore, a mating groove is provided on the side of the buckle hole near the inner panel of the door, and the buckle piece is slidably connected to the mating groove.
[0009] Furthermore, the support assembly includes a fixed rod and a telescopic rod, with an adjustment assembly connecting the fixed rod and the telescopic rod. The ends of the fixed rod and the telescopic rod that are far apart from each other are respectively connected to two locking blocks.
[0010] Furthermore, both the fixed rod and the telescopic rod have internal threaded holes at their ends that are far apart from each other. The internal threaded holes are connected to threaded blocks, and the threaded blocks are fixedly connected to the ends of the snap-fit blocks that are far away from the snap-fit pieces.
[0011] Furthermore, an installation nut is fixedly connected to the outer wall of the threaded block near the snap-fit block.
[0012] Furthermore, the adjustment assembly includes a support tube and an adjusting nut. One end of the support tube is fixedly connected to the fixed rod, and the telescopic rod is slidably connected to the inner wall of the support tube. An annular groove is provided on the outer wall of the support tube near the telescopic rod. A connecting ring is rotatably connected in the annular groove. The cross-section of the connecting ring is L-shaped. The end of the connecting ring away from the annular groove is fixedly connected to the adjusting nut. The adjusting nut is sleeved on the outside of the telescopic rod and threadedly connected to the telescopic rod.
[0013] Compared with the prior art, the present invention has the following beneficial effects: This segmented hinge reinforcement plate, with its positioning structure facilitating welding and installation, utilizes snap-fit structures at both ends of the support assembly to connect with the snap-fit holes on the sides of the upper and lower hinge reinforcement plates, effectively limiting the distance between the two reinforcement plates. This design ensures that the distance between the upper and lower hinge reinforcement plates welded to the inner door panel precisely matches the actual required installation spacing of the upper and lower hinges in the door, thereby guaranteeing smooth opening and closing of the door after assembly and significantly improving the installation accuracy of the hinge reinforcement plates and the overall assembly effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Please see Figures 1 to 5 A segmented hinge reinforcement plate with a positioning structure for easy welding and installation includes an upper hinge reinforcement plate 2 and a lower hinge reinforcement plate 3 installed on the inner panel 1 of a car door. Two support components 4 are connected between the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3. Several snap-fit holes 101 are provided through the side walls of the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3. The snap-fit holes 101 of the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3 are symmetrically arranged. Both ends of the support components 4 are connected to snap-fit components 5, which are connected to the snap-fit holes 101.
[0018] The main improvement of this utility model lies in improving the installation accuracy of the upper and lower hinge reinforcement plates, such as... Figures 1 to 5 As shown, the segmented hinge reinforcement plate with positioning structure that facilitates welding installation in this utility model is used by using the snap-fit components 5 at both ends of the support component 4 to snap into the corresponding snap-fit holes 101 of the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3. The installation of the two support components 4 fixes the distance and relative position between the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3. Then, the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3 are welded and fixed close to the inner panel 1 of the car door. This design ensures that the distance between the welded upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3 on the inner panel 1 of the car door is precisely matched with the actual required upper and lower hinge installation spacing of the inner panel 1 of the car door. This ensures that the car door can open and close smoothly through the upper and lower hinges after assembly, significantly improving the installation accuracy and overall assembly effect of the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3.
[0019] like Figures 1 to 5As shown, the snap-fit assembly 5 includes a snap-fit block 51 and a snap-fit piece 52. The snap-fit block 51 is connected to the end of the support assembly 4, and the other end of the snap-fit block 51 passes through the snap-fit hole 101 and is fixedly connected to the snap-fit piece 52. The snap-fit piece 52 at the end of the support assembly 4 is inserted through the larger end of the snap-fit hole 101, so that the snap-fit block 51 is located in the snap-fit hole 101. Then, the snap-fit block 51 is moved to the smaller end in the snap-fit hole 101, and in cooperation with the snap-fit piece 52, the snap-fit block 51 is snapped into the snap-fit hole 101, thus completing the connection and support between the support assembly 4 and the upper hinge reinforcing plate 2 or the lower hinge reinforcing plate 3. The smaller end of the snap-fit hole 101 of the upper hinge reinforcing plate 2 faces upward, and the smaller end of the snap-fit hole 101 of the lower hinge reinforcing plate 3 faces downward.
[0020] like Figure 3 and Figure 4 As shown, a mating groove 102 is provided on the side of the snap-fit hole 101 near the inner door panel 1, and the snap-fit piece 52 is slidably connected to the mating groove 102. The design of the mating groove 102 ensures that when the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3 contact the inner door panel 1, the snap-fit piece 52 will not obstruct the contact between the hinge reinforcement plate and the inner door panel 1, thus improving the fit and tightness of subsequent welding and fixing.
[0021] like Figures 1 to 5 As shown, the support assembly 4 includes a fixed rod 41 and a telescopic rod 42. An adjustment assembly 6 connects the fixed rod 41 and the telescopic rod 42. The ends of the fixed rod 41 and the telescopic rod 42 that are far apart from each other are respectively connected to two locking blocks 51. The distance between the telescopic rod 42 and the fixed rod 41 can be adjusted by the adjustment assembly 6, thereby adjusting the distance between the upper hinge reinforcement plate 2 and the lower hinge reinforcement plate 3 according to the actual installation distance of the upper and lower hinges, adapting to the installation positioning of the upper and lower hinge reinforcement plates of different vehicle models.
[0022] like Figures 1 to 5 As shown, both the fixed rod 41 and the telescopic rod 42 have internally threaded holes 401 at their ends that are far apart from each other. Threaded blocks 43 are internally threaded into the internally threaded holes 401, and the threaded blocks 43 are fixedly connected to the end of the snap-fit block 51 that is far away from the snap-fit piece 52. The connection between the threaded blocks 43 and the internally threaded holes 401 facilitates the installation and disassembly of the snap-fit assembly 5 and the support assembly 4.
[0023] like Figure 4 As shown, a mounting nut 44 is fixedly connected to the outer wall of the threaded block 43 near the snap-fit block 51. When screwing the threaded block 43 into the internal threaded hole 401 or removing it from the internal threaded hole 401 for replacement, the mounting nut 44 allows the threaded block 43 to be rotated more smoothly.
[0024] like Figures 1 to 5As shown, the adjusting assembly 6 includes a support tube 61 and an adjusting nut 62. One end of the support tube 61 is fixedly connected to the fixed rod 41, and the telescopic rod 42 is slidably connected to the inner wall of the support tube 61. An annular groove 601 is formed on the outer wall of the support tube 61 near the end of the telescopic rod 42. A connecting ring 63 is rotatably connected in the annular groove 601. The cross-section of the connecting ring 63 is L-shaped. The end of the connecting ring 63 away from the annular groove 601 is fixedly connected to the adjusting nut 62. The adjusting nut 62 is sleeved on the outside of the telescopic rod 42 and threadedly connected to the telescopic rod 42. When adjusting the overall length between the fixed rod 41 and the telescopic rod 42, the telescopic rod 42 can be moved up and down inside the support tube 61 by rotating the adjusting nut 62, thus allowing the telescopic rod 42 to extend and retract within the support tube 61. At the same time, the connection between the adjusting nut 62 and the annular groove 601 through the connecting ring 63 ensures that the adjusting nut 62 rotates smoothly while maintaining a stable connection between the adjusting nut 62 and the support tube 61.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
