Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an automotive hinge strength testing device. Background Technology
[0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between them. Hinges can be made of movable components or foldable materials. Hinges are often installed on cabinets and are mainly classified by material into stainless steel hinges and iron hinges. Multiple hinges are also installed in cars to control the opening and closing of doors and trunk doors. The quality inspection of car hinges now requires multiple processes, including testing the hinge's own strength.
[0003] Currently, hinges are typically tested for strength using pressure and tensile stress tests to assess their stability. However, there is no dedicated equipment for testing the hinge's strength under repeated bending. This makes it difficult to accurately calculate the hinge's performance after multiple bends and uses, affecting its overall performance and preventing a comprehensive assessment of its strength.

[0008] As a preferred technical solution of this utility model, the test platform is provided with a swing groove inside, which works in conjunction with the swing rod to swing back and forth.
[0009] As a preferred technical solution of this utility model, the device further includes a reciprocating mechanism, which includes a blocking plate, a through rod, meshing gears, a mating component, a main gear, a linkage shaft, and a drive motor. The test platform has an installation slot for mounting the reciprocating mechanism. The blocking plate is installed in the installation slot. The through rod is symmetrically rotated and installed on the side of the blocking plate. The meshing gears are installed outside the through rod, and the two sets of meshing gears mesh with each other. The mating component is installed outside the through rod, and the main gear is meshed between the mating components. The linkage shaft is installed on the side of the pushing mechanism, and the end of the linkage shaft is connected to the main gear.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0025] Depend on Figure 1 As shown, it is a structural schematic diagram of the automobile hinge strength testing device in this embodiment, including a test platform 1 for positioning and preventing the hinge body 2, and a pushing mechanism 3 for testing the opening and closing strength of the hinge body 2 is installed on the side of the test platform 1.
[0026] In use, the hinge body 2 to be tested is placed on the surface of the test platform 1. The hinge body 2 consists of a base and a rotating end, with the base and rotating end rotatably connected. Using the structure of the test platform 1 itself, the hinge body 2 is initially positioned and installed. Then, the reciprocating oscillating pushing mechanism 3 is used to push the rotating end of the hinge body 2, causing the rotating end of the hinge body 2 to oscillate back and forth. By increasing the number of oscillations, the strength of the hinge body 2 can be stably tested, thus realizing the test of the number of uses and service life of the hinge body 2.
[0027] From the appendix Figure 2 As shown, it is a structural schematic diagram of the pushing mechanism 3 in this embodiment. The pushing mechanism 3 includes a swing rod 31, a pulling member 32 and a pushing rod 33. The swing rod 31 is rotatably mounted on the side of the test platform 1, the pulling member 32 is mounted on the end of the swing rod 31, and the pushing rod 33 is fixedly mounted on the side of the swing rod 31 near the hinge body 2.
[0028] During use, the swing arm 31 swings itself, and the end of the swing arm 31 deflects towards the side closer to the rotating end of the hinge body 2. At this time, the push rod 33 pushes the rotating end of the hinge body 2, so that the distance between the rotating end and the base decreases and the angle changes. Then the swing arm 31 rotates away from the hinge body 2. At this time, the pull member 32 pulls the rotating end of the hinge body 2, so that the distance between the rotating end and the base increases, thereby controlling the opening and closing and operation of the hinge body 2 itself.
[0029] From the appendix Figure 3 As shown, it is a structural schematic diagram of the pulling member 32 in this embodiment. The pulling member 32 includes a connecting chain 321, a mounting thread seat 322 and a mounting nut 323. The connecting chain 321 is installed at the end of the swing rod 31, the mounting thread seat 322 is installed at the end of the connecting chain 321, the mounting thread seat 322 is slidably inserted into the inner hole groove of the hinge body 2, and the mounting nut 323 is threadedly installed on the outside of the mounting thread seat 322.
[0030] During use, the hinge body 2 has multiple sets of holes and slots to assist in its installation. The mounting thread seat 322 is inserted into the hole and slot at the rotating end of the hinge body 2. Then, as the mounting nut 323 moves on the outer surface of the mounting thread seat 322, the position of the mounting thread seat 322 is locked. Subsequently, when the swing rod 31 deflects away from the rotating end of the hinge body 2, the connecting chain 321 pulls the position of the mounting thread seat 322, thereby realizing the opening and closing of the hinge body 2 itself.
[0031] From the appendix Figure 2 As shown, the test platform 1 has an internal swing groove 34 that works with the swing rod 31 to swing back and forth. During use, it provides sufficient space for the swing rod 31 to swing, which helps the components to operate stably.
[0032] From the appendix Figure 4 As shown, this is a schematic diagram of the reciprocating mechanism 4 in this embodiment. The device also includes the reciprocating mechanism 4, which includes a baffle plate 41, a through rod 42, a meshing gear 43, a mating part 44, a main gear 45, a linkage shaft 46, and a drive motor 47. The test platform 1 has an installation slot for mounting the reciprocating mechanism 4. The baffle plate 41 is installed in the installation slot. The through rod 42 is symmetrically rotated and installed on the side of the baffle plate 41. The meshing gear 43 is installed outside the through rod 42, and the two sets of meshing gears 43 mesh with each other. The mating part 44 is installed outside the through rod 42, and the main gear 45 is meshed between the mating parts 44. The linkage shaft 46 is installed on the side of the push mechanism 3, and the end of the linkage shaft 46 is connected to the main gear 45. The drive motor 47 is fixedly installed inside the test platform 1, and the output end of the drive motor 47 is connected to the end of one set of through rods 42.
[0033] During use, the output end of the drive motor 47 drives one of the through rods 42 to rotate. At this time, the meshing gears 43 installed on the outside of both through rods 42 make the two through rods 42 rotate in different directions, driving the two sets of mating parts 44 to mesh with the main gear 45 in turn. By utilizing the different rotation directions of the two sets of mating parts 44 and the design of the initial angle of the mating parts 44, the main gear 45 can achieve reciprocating rotation, providing power for the reciprocating swing of the swing rod 31.
[0034] From the appendix Figure 4 As shown, the mating component 44 consists of a rotating ring and a sector-shaped toothed block. The rotating ring is installed outside the through rod 42, and the sector-shaped toothed block is installed on the side of the rotating plate. The sector-shaped toothed block meshes with the main gear 45.
[0035] In use, the sector-shaped toothed blocks are installed on the side of the rotating plate. The swing amplitude of the swing rod 31 varies depending on the number and angle of the toothed blocks in the sector-shaped toothed blocks. The angle of the swing rod 31 is controlled by controlling the number of toothed blocks in the sector-shaped toothed blocks.
[0036] From the appendix Figure 5 As shown, it is a structural schematic diagram of the test platform 1 in this embodiment. The test platform 1 includes a test table 11, a positioning screw 12 and a compression nut 13. The test table 11 is a placement platform for the hinge body 2. The positioning screw 12 is symmetrically installed on the surface of the test table 11 and is connected to the internal groove of the hinge body 2. The compression nut 13 is threadedly installed on the outside of the positioning screw 12.
[0037] In use, by placing the hinge body 2 on the surface of the testing table 11, the position of the base of the hinge body 2 is initially defined by the design of two sets of positioning screws 12. Then, by cooperating with the compression nut 13, the position of the base in the hinge body 2 is locked, which helps the rotating end in the hinge body 2 to swing back and forth.
[0038] From the appendix Figure 5 As shown, there are two sets of positioning screws 12. The two sets of positioning screws 12 are symmetrically distributed around the pushing mechanism 3 as the axis. In use, they can quickly lock the position of the hinge body 2, so that when the pushing mechanism 3 swings back and forth, the pushing rod 33 in the pushing mechanism 3 can push the rotating end of the hinge body 2.
[0039] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
