Abstract

A hinge mechanism capable of being automatically popped up or stored, a spectacle frame, and spectacles. The hinge mechanism comprises a fixed portion (1) and a movable portion (2), wherein an end portion of the fixed portion (1) is provided with a movable fixing structure; one end of the movable portion (2) is provided with elastic strips, each elastic strip is provided with a movable shaft (23) that cooperates with the movable fixing structure, and the elastic strip which is located in a storage direction for rotation is a bent portion. In case of the two movable shafts (23) being located at diagonal vertexes of the movable fixing structure, the amount of deformation of the two elastic strips is at a minimum when the distance between the two movable shafts (23) is at a maximum, and the amount of deformation of the two elastic strips is at a maximum when the distance between the two movable shafts (23) is at a minimum. Due to the fact that the movable shafts (23) cooperate with the movable fixing structures at the two elastic strips, the two elastic strips are necessarily compressed from a open state to a stored state or from the stored state to the open state, the hinge mechanism is unstable when the elastic strips are at maximum compression, and the hinge mechanism moves to the stable stored or open state under the action of the elastic strips merely after the movable shafts (23) cross a balance point. The angle of rotation for force application during opening or folding is reduced, and the structure is simple, stable and reliable. The hinge mechanism is widely applied to a movable connection between objects.

As shown in FIG. 1 and FIG. 5 , the present invention provides a first embodiment of a hinge mechanism that can be opened or retracted automatically.

The hinge mechanism that can be automatically bounced or accommodated includes a fixed part 1 and a movable part 2. The end of the fixed part 1 is provided with a movable fixing structure; The second elastic bar 22, each elastic bar is provided with a movable shaft 23 that cooperates with the movable fixed structure. The bending part 25 protruding from the direction of the first elastic bar 21, when the two movable shafts 23 are located at the diagonal vertices of the movable fixed structure, when the distance between the two movable shafts 23 is the largest, the shape variable of the two elastic bars is the smallest, and the distance between the two movable shafts 23 When the spacing between the two bullets is the smallest, the variable of the two elastic bars is the largest.

Specifically, the movable fixing structure is provided with two movable fixing holes 13 arranged in parallel, and a gap 10 for accommodating elastic bars is provided between the two movable fixing holes 13 . During installation, the ends of the two spring bars are respectively located in the gap 10, and the two ends of each movable shaft 23 are located in the movable fixed hole 13, and contact with the hole wall of the movable fixed hole 13, preferably maintaining a moderate pressure. The movable fixing hole adopts a square movable fixing hole structure in this embodiment. A V-shaped gap 20 is formed between the two elastic bars. The elastic material, such as memory material, can keep a certain active force between the movable shaft 23 and the movable fixing hole 13, and cannot move automatically when there is no external force.

When the two movable shafts 23 are located at the two diagonal vertices of the square movable fixed hole 13, the distance between the two movable shafts 23 is the largest, and the force with the square movable fixed hole 13 is the smallest, and under the structural characteristics of the diagonal vertices, they are at any When one set of diagonal vertices, the movable shaft 23 and the square movable fixing hole 13 can be in a relatively stable state, and the angle between the positions of the two sets of diagonal vertices is 90 degrees. When the two movable shafts 23 move from one group of diagonal vertices to another diagonal vertices, the two movable shafts 23 need to be squeezed toward each other, and a stable state cannot be formed on the wall of any square movable fixing hole 13 . When moving to the middle of the two vertices, that is, reaching the unstable point of balance and applying a little external force, the movable part 2 will move to the direction of the force, and the position will change. The bending part is located on one side of the elastic bar that rotates in the storage direction, so that when it is rotated in the storage direction, the inner elastic bar, that is, the second elastic bar, is easier to change its shape first, thereby reducing the difficulty of rotation during storage.

Since the movable shaft 23 is in a stable state when the two elastic bars cooperate with the movable fixed structure, it is in a stable state when it is stored or opened, and it is necessary to compress the two elastic bars during the process from opening to storing or from storing to opening, and it is at the maximum compression The position is unstable in the state, so when opening or storing, only when the movable axis crosses the unstable point of balance, the storing or opening can be realized under the action of the two elastic bars until the stable position. It can reduce the forceful rotation angle when opening or storing, and it is not easy to open after storing or store in the open state, and the structure is simple, stable and reliable.

According to requirements, the opposite sides of the square movable fixing hole are respectively provided with limiting parts 14, and the connecting line between the two limiting parts 14 is inclined to the storage direction. The limiting part 14 can prevent the two movable shafts 23 from continuing to rotate in the original direction after reaching the diagonal apex, so as to realize one-way rotation, and at the same time avoid damage to the hinge structure due to excessive rotation.

According to requirements, the diagonal of the square fixing hole is consistent with the direction after opening or storage.

According to requirements, the movable fixing hole is a square movable fixing hole, which can ensure that the force is basically the same as that of the movable shaft 23 at two sets of diagonal vertices, which is preferred. Of course, the movable fixing holes can be arranged as a structure such as a rectangle or a parallelogram, and the rotation angle can also be 90 degrees.

As shown in FIG. 6 and FIG. 7 , the present invention also provides a second embodiment of the hinge mechanism that can be opened or retracted automatically.

One movable fixing hole is used, and two sets of elastic bars are used. Each set of elastic bars is composed of two elastic bars distributed in a V shape. The two sets of elastic bars are arranged in parallel, and there are clamping movable fixing holes between them. The gap 24, and other structures are the same as those of the above-mentioned embodiments, and will not be repeated here.

As shown in FIG. 8 and FIG. 9 , the present invention also provides a third embodiment of the hinge mechanism that can be opened or retracted automatically.

The sliding contact surface that cooperates with the two movable shafts 23 when the movable fixing hole is accommodated or opened is provided with an inward arc-shaped protrusion 15 . Since the arc-shaped protrusions 15 are in an unstable position between two groups of diagonal vertices, when the two movable shafts 23 move to the corresponding arc-shaped protrusions 15 at the same time, the balance becomes less difficult when the force increases. It can thus be quickly placed in a stowed or opened position. Other structures can adopt the structures of the above two embodiments, that is, this embodiment can be used in combination with the above examples, and the specific combination will not be repeated.

As shown in FIGS. 10-11 , the present invention also provides a fourth embodiment of a hinge mechanism that can be automatically opened or stored.

The hinge mechanism that can be automatically bounced or accommodated includes a fixed part 1 and a movable part 2. The end of the fixed part 1 is provided with one or two groups of bar-shaped hole structures arranged in parallel to each other, and each group of bar-shaped hole structures includes two Bar-shaped hole 13; one end of the movable part 2 is provided with two elastic bars that are arranged in a V shape, that is, the first elastic bar 21 and the second elastic bar 22, and each elastic bar is provided with an activity that cooperates with the bar-shaped hole 13. Axes, two movable shafts 23 are positioned at the maximum distance between the two elastic bar-shaped variables, and the two elastic bar-shaped variables are the largest when the distance between the two active shafts is the smallest.

This embodiment is described by taking two sets of strip-shaped hole structures arranged parallel to each other as an example.

Specifically, the bar-shaped hole structure is provided with two bar-shaped holes 13 arranged in parallel, and there is a gap (not shown in the drawings) for accommodating elastic bars between the two bar-shaped holes 13 . During installation, the ends of the two elastic bars are respectively located in the gap, and the two ends of each movable shaft 23 are located in the two bar-shaped holes 13, and are in contact with the walls of the two bar-shaped holes 13, preferably maintaining a moderate pressure. A V-shaped gap is formed between the two elastic bars. The elastic material, such as a memory material, can keep a certain active force between the movable shaft 23 and the movable fixing hole 13, and can not move automatically when keeping non-external force.

When the two movable shafts 23 are respectively located at the different side ends of the two strip holes 13, that is, the strip hole 13 has a movable shaft 23, the distance between the two movable shafts 23 is the largest, and the distance between the movable shaft 23 and the two strip holes 13 The force between them is the smallest, and under the action of the end features of the strip-shaped holes 13, when they are at the ends of two strip-shaped holes 13 on different sides, the movable shaft 23 and the strip-shaped holes 13 can be in a relatively stable state. When the two movable shafts 23 move to the other ends of the two bar-shaped holes 13 on different sides, the two movable shafts 23 need to be pressed against each other, and neither of them can form a stable state during the moving process. When moving to the middle part of the same strip hole 13, that is to say, a little external force is applied to the unstable point of balance, and the movable shaft 23 will move to the direction of application of force, and the position will change.

Since the movable shaft 23 cooperates with the bar-shaped hole 13 in the two elastic bars, it is in a stable state when it is stored or opened, and the two elastic bars must be compressed from the opening to the storage or from the storage to the opening process, and it is at the maximum The position is unstable in the compressed state, so when opening or storing, only when the movable shaft crosses the unstable point of balance, it can be stored or opened to a stable position under the action of the two elastic bars. It can reduce the forceful rotation angle when opening or storing, and it is not easy to open after storing or store in the open state, and the structure is simple, stable and reliable. At the same time, two bar-shaped holes 13 can be used to realize unidirectional rotation within a certain range and avoid damage to the hinge structure due to excessive rotation.

According to needs, the elastic bar is provided with a bending part 25 (refer to the structure in Figure 3), and the bending part 25 is located on the side elastic bar that rotates in the storage direction, that is, on the second elastic bar 22, which can be rotated in the storage direction. When turning, the inner elastic bar, that is, the second elastic bar, is easier to change its shape first, thereby reducing the difficulty of turning during storage. The strip-shaped holes 13 are inclined to the storage direction, preferably two strip-shaped holes 13 are arranged in parallel, and the two strip-shaped holes are arranged inclined at 45 degrees to the storage direction. The direction of rotation angle can be adjusted.

According to needs, the arc-shaped protrusion 15 is provided in the bar-shaped hole 13 (refer to the structure in Fig. 8). Since the arc-shaped protrusion 15 is in the unstable position of the bar-shaped hole 13, when the two movable shafts 23 The corresponding arc-shaped protrusion 15 makes the balance less difficult when the force increases, so that it can quickly be in the storage or opening position. Other structures can adopt the structures of the above two embodiments, that is, this embodiment can be used in combination with the above examples, and the specific combination will not be repeated.

In order to ensure that the movable shaft 23 is separated in use, a limit cap (not shown in the drawings) is provided on the outer side of the movable shaft 23. The limit cap is fixed with the square fixing hole 13 or the strip hole, and is located outside the fixed part 1. Avoid separation of the movable shaft 23 from the fixed part, so that a stable connection between the fixed part and the movable part can be formed without an external structure, and no loose connection will occur.

The present invention also provides an embodiment of a spectacle frame. The spectacle frame includes a spectacle frame and spectacle feet, and a hinge mechanism is provided between the spectacle frame and spectacle feet. content, no more details.

As shown in Figure 12, the present invention also provides an embodiment of glasses, the glasses include a frame 1 and temples 2, a hinge mechanism A is provided between the frame 1 and temples 2, and the hinge mechanism A adopts the above-mentioned implementation For example structure, specific principles and effects, etc., refer to the above content, and will not repeat them here.
