Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hinge technology, and in particular relates to a multi-segment buffer hinge structure. Background Technology
[0002] Hinges generally consist of hinge plates, a pivot, and a pin. The hinge plates are typically two flat metal pieces, forming the main connection; one is fixed to one object, and the other to another. The pivot passes through a hole in the center of the hinge plates, allowing the two hinge plates to rotate around it, much like a door rotates around a hinge. The pin primarily serves to secure the pivot, preventing it from coming loose during use. Currently, common hinges utilize a rotating connection between two sets of mounting brackets. However, this rotation between the two sets of brackets lacks cushioning. Few hinges with cushioning use dampers, but dampers are cumbersome to manufacture and only cushion the rotation of the pivot, making them prone to damage over time. Furthermore, this single-stage cushioning provides poor overall cushioning. Therefore, a multi-stage cushioning hinge structure is needed.
[0003] It should be noted that the above content falls within the scope of technical knowledge for practical individuals and does not necessarily constitute prior art. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing hinges that use a single damping buffer and have poor buffering effect, and to propose a multi-segment buffer hinge structure.
[0005] To achieve the above objectives, this utility model proposes a multi-segment buffer hinge structure, including a main mounting frame, a side mounting frame, and a rotating shaft. A main rotating shaft is rotatably connected to one side of the main mounting frame, and one end of the main rotating shaft is rotatably connected to the main mounting frame. A secondary rotating shaft is rotatably connected to the middle of the main rotating shaft via a rotating shaft. The middle of the secondary rotating shaft is rotatably connected to the main rotating shaft, and the end of the secondary rotating shaft away from the main rotating shaft is rotatably connected to the side mounting frame. A toothed block is installed on the end of the main rotating shaft near the main mounting frame. The toothed blocks are evenly distributed on the arc-shaped side surface of the main rotating shaft near the main mounting frame. A damping block is installed on one side of the main rotating shaft. The damping block has an arc-shaped structure. Two sets of through holes are formed on the surface of the damping block. A sliding rod is inserted into each of the two sets of through holes. One end of the sliding rod passes through the damping block away from the main mounting frame, and the other end of the sliding rod is fixedly connected to the main mounting frame. A toothed opening is formed on one side of the arc-shaped concave surface of the damping block, and the toothed opening of the damping block meshes with the toothed block of the main rotating shaft.
[0006] Preferably, a spring is installed at the middle position of the damping block, one end of the spring is fixedly connected to the damping block, and the other end of the spring is fixedly connected to the main mounting bracket.
[0007] Preferably, a connecting rod is rotatably connected to the end of the main rotating shaft away from the damping block, one end of the connecting rod is rotatably connected to the main rotating shaft, and the other end of the connecting rod is rotatably connected to the side mounting bracket.
[0008] Preferably, a damping rod is rotatably connected to one end of the secondary rotating shaft away from the side mounting bracket, one end of the damping rod is rotatably connected to the secondary rotating shaft, and the other end of the damping rod is rotatably connected to the main mounting bracket.
[0009] Preferably, a slider is installed at the middle position of the damping rod, and a groove is provided on the side of the main mounting bracket. The position of the groove corresponds to the position of the slider, and the groove has an arc-shaped opening. The slider is slidably connected in the groove, and there is friction between the slider and the groove.
[0010] Preferably, two sets of connecting rods are symmetrically rotatably connected to both sides of the side mounting bracket, and two sets of auxiliary rotating shafts are symmetrically installed on both sides of the side mounting bracket. One set of the auxiliary rotating shafts is symmetrically installed on the side of the main mounting bracket away from the main rotating shaft, and one set of connecting rods is symmetrically installed on the side of the main mounting bracket away from the damping rod. The auxiliary rotating shafts on the side mounting bracket are rotatably connected to the damping rod and the connecting rods on the main mounting bracket, respectively. The main rotating shaft and the auxiliary rotating shafts on the main mounting bracket are rotatably connected to the two sets of connecting rods on the side mounting bracket, respectively.
[0011] The multi-segment buffer hinge structure proposed in this utility model can bring the following beneficial effects:
[0012] 1. In this utility model, the main mounting bracket and the side mounting bracket are connected by a connecting rod, a main rotating shaft, and a secondary rotating shaft to achieve the purpose of adjusting the angle between the main mounting bracket and the side mounting bracket, forming a hinge. The slider on the damping rod is slidably connected to the slide groove to increase friction and improve the buffering force between the hinges.
[0013] 2. In this utility model, a damping block is installed on one side of the main rotating shaft. The damping block meshes with the toothed block on the main rotating shaft, and the damping block slides on two sets of sliders. The position of the damping block is fixed. When the spring lifts the damping block, the damping block meshes with the main rotating shaft, locking it to buffer the main rotating shaft again during the rotation process, forming a multi-stage buffering purpose. The damping block limits the rotation of the main rotating shaft and fixes the angle of the main mounting bracket and the side mounting bracket. Pressing the spring separates the damping block from the main rotating shaft, and then the angle is adjusted again. Attached Figure Description

[0022] like Figure 1-4As shown, the present invention proposes a multi-segment buffer hinge structure, including a main mounting frame 1, a side mounting frame 2, and a rotating shaft 13. A main rotating shaft 3 is rotatably connected to one side of the main mounting frame 1. One end of the main rotating shaft 3 is rotatably connected to the main mounting frame 1, and a secondary rotating shaft 4 is rotatably connected to the middle position of the main rotating shaft 3 via the rotating shaft 13. The middle position of the secondary rotating shaft 4 is rotatably connected to the main rotating shaft 3, and the end of the secondary rotating shaft 4 away from the main rotating shaft 3 is rotatably connected to the side mounting frame 2. A toothed block 6 is installed on the end of the main rotating shaft 3 near the main mounting frame 1. The toothed blocks 6 are evenly distributed on the arc-shaped side surface of the main rotating shaft 3 near the main mounting frame 1. A damping block 7 is installed on one side of the main rotating shaft 3. The damping block 7 has an arc-shaped structure, and two sets of through holes 14 are opened on the surface of the damping block 7. A sliding rod 8 is inserted into each of the two sets of through holes 14. One end of the sliding rod 8 passes through the damping block 7 away from the main mounting frame 1, and the sliding rod 8... The other end is fixedly connected to the main mounting bracket 1. The damping block 7 has a toothed opening 15 on one side of its arc-shaped concave surface, and the toothed opening 15 of the damping block 7 meshes with the toothed block 6 of the main rotating shaft 3. A spring 12 is installed in the middle of the damping block 7. One end of the spring 12 is fixedly connected to the damping block 7, and the other end of the spring 12 is fixedly connected to the main mounting bracket 1. A damping block 7 is installed on one side of the main rotating shaft 3. The damping block 7 meshes with the toothed block 6 on the main rotating shaft 3, and the damping block 7 slides on two sets of sliders 11. The position of the damping block 7 is fixed. When the spring 12 pops up the damping block 7, the damping block 7 meshes with the main rotating shaft 3, and locks the main rotating shaft 3 to buffer it again during the rotation process, forming a multi-stage buffering purpose. The damping block 7 restricts the rotation of the main rotating shaft 3 and fixes the angle of the main mounting bracket 1 and the side mounting bracket 2. Pressing the spring 12 separates the damping block 7 from the main rotating shaft 3, and then the angle is adjusted again.
[0023] The main rotating shaft 3 is rotatably connected to a connecting rod 5 at one end away from the damping block 7. One end of the connecting rod 5 is rotatably connected to the main rotating shaft 3, and the other end of the connecting rod 5 is rotatably connected to the side mounting bracket 2. The auxiliary rotating shaft 4 is rotatably connected to a damping rod 10 at one end away from the side mounting bracket 2. One end of the damping rod 10 is rotatably connected to the auxiliary rotating shaft 4, and the other end of the damping rod 10 is rotatably connected to the main mounting bracket 1. A slider 11 is installed in the middle of the damping rod 10. A sliding groove 9 is opened on the side of the main mounting bracket 1. The position of the sliding groove 9 corresponds to the position of the slider 11, and the sliding groove 9 is an arc-shaped groove. The slider 11 is slidably connected in the sliding groove 9, and there is friction between the slider 11 and the sliding groove 9. By utilizing the rotational connection between the main mounting bracket 1 and the side mounting bracket 2 through the connecting rod 5, the main rotating shaft 3, and the auxiliary rotating shaft 4, the angle between the main mounting bracket 1 and the side mounting bracket 2 can be adjusted, forming a hinge. The slider 11 on the damping rod 10 is slidably connected to the sliding groove 9, increasing the friction and improving the buffering force between the hinges.
[0024] The side mounting bracket 2 is symmetrically connected to two sets of connecting rods 5 on both sides, and two sets of auxiliary rotating shafts 4 are symmetrically installed on both sides of the side mounting bracket 2. The main mounting bracket 1 is symmetrically installed with a set of auxiliary rotating shafts 4 on the side away from the main rotating shaft 3, and a set of connecting rods 5 is symmetrically installed on the side away from the damping rod 10. The auxiliary rotating shafts 4 on the side mounting bracket 2 are rotatably connected to the damping rod 10 and the connecting rods 5 on the main mounting bracket 1, respectively. The main rotating shaft 3 and the auxiliary rotating shafts 4 on the main mounting bracket 1 are rotatably connected to the two sets of connecting rods 5 on the side mounting bracket 2, forming a hinge.
[0025] The working principle of this utility model is as follows: A damping block 7 is installed on one side of the main rotating shaft 3. The damping block 7 meshes with the toothed block 6 on the main rotating shaft 3, and the damping block 7 slides on two sets of sliders 11. The position of the damping block 7 is fixed. When the spring 12 pops up the damping block 7, the damping block 7 meshes with the main rotating shaft 3, and locks it to buffer the main rotating shaft 3 again during the rotation process, forming a multi-stage buffering purpose. The damping block 7 limits the rotation of the main rotating shaft 3 and fixes the angle of the main mounting frame 1 and the side mounting frame 2. Pressing the spring 12 separates the damping block 7 from the main rotating shaft 3, and then the angle is adjusted again. The rotational connection between the main mounting frame 1 and the side mounting frame 2 through the connecting rod 5, the main rotating shaft 3, and the auxiliary rotating shaft 4 achieves the purpose of adjusting the angle between the main mounting frame 1 and the side mounting frame 2, forming a hinge. The slider 11 on the damping rod 10 slides and connects with the slide groove 9 to increase the friction and improve the buffering force between the hinges.
