Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

Example 1:

as shown in fig. 1-6, a antimagnetic rotation limiting structure comprises a base 1 and a support plate 2 rotatably connected with the base 1, wherein the support plate 2 is provided with a first state of folding and accommodating relative to the base 1 and a second state of rotating and unfolding relative to the base 1, a first magnet 3 and a second magnet 4 are arranged on the support plate 2, and the second magnet 4 and the first magnet 3 are respectively positioned at two ends of a rotation point of the support plate 2;

the base 1 is provided with a third magnet 5 matched with the first magnet 3, the magnetic poles of the third magnet 5 and the first magnet 3 are the same to provide thrust, one end of the base 1 is provided with a fourth magnet 6 matched with the second magnet 4, and the magnetic poles of the fourth magnet 6 and the second magnet 4 are opposite to provide magnetic attraction;

a locking mechanism 7 for locking the support plate 2 in the first state and accumulating thrust is arranged on one side of the base 1; when the locking mechanism 7 is unlocked, the supporting plate 2 is firstly converted into a second state from a first state under the action of thrust, and then the fourth magnet 6 and the second magnet 4 are magnetically attracted to be matched to realize rotation limit.

The first magnet may be a magnet provided in the wireless charger, or may be a magnet provided separately from the wireless charger. All of which should be included within the scope of this application.

The utility model skillfully utilizes the principle of the like attraction and the opposite repulsion of the magnets and the principle of the lever (rotating around the pivot), and achieves the aim of the utility model under the combination of the two principles.

First, the first magnet 3 of the present application may be a magnetic type wireless charger. So that the first magnet 3 of the present application is alternatively magnetically attracted to the handset (generating attraction force) or is engaged with the third magnet 5 (generating thrust force). As can be seen from this, the magnetic type wireless charger of the present application is used as a suction source for the cellular phone when in use, and as a thrust source for the support plate 2 to be rotated and unfolded when in folding and storage.

Secondly, the first magnet 3 and the second magnet 4 are distributed at two ends of the rotation pivot of the support plate 2, so that one end of the support plate 2 provides thrust and the other end provides suction to drive the support plate 2 to rotate around the rotation point. It is emphasized that: the thrust and suction forces do not always coexist in the present application, but are generated sequentially. The supporting plate 2 is firstly converted into a second state from a first state under the action of thrust, and then the fourth magnet 6 and the second magnet 4 are magnetically matched to realize rotation limit.

Thirdly, the present application uses the locking mechanism 7 to lock the support plate 2 in the first state. On the one hand, the supporting plate 2 is maintained in a folded and contained state; on the other hand, the pushing force between the third magnet 5 and the first magnet 3 is also accumulated, and once the lock mechanism 7 is unlocked, the pushing force drives the support plate 2 to change from the first state to the second state.

Further, when in the first state, the support plate 2 is parallel to the base 1, and the support plate 2 is folded and stored relative to the base 1.

When in the second state, the support plate 2 is perpendicular to the base 1, and the support plate 2 is rotated and unfolded relative to the base 1 (as shown in fig. 1). In addition, the angle between the support plate 2 and the base 1 can be adjusted by a person skilled in the art, and is not limited to the vertical state. The above is only a preferred embodiment.

Further, the first magnet 3 and the second magnet 4 are located at both sides of the support plate 2, respectively, wherein: the second magnet 4 is located on the side of the support plate 2 near the base 1.

Further, the first magnet 3 and the second magnet 4 are both located on one side of the support plate 2 near the base 1.

The above is preferable, and known: the closer the magnet is to the target object, the stronger the suction/thrust force generated by the magnet. The first magnet 3 or the second magnet 4 may be disposed on a side of the support plate 2 away from the base 1. Although the suction/pushing force generated through the support plate 2 is correspondingly weakened when in use, the purpose of the utility model can be achieved as long as the magnetism of the selected magnet is strong. And therefore should be included in the scope of protection.

Further, the base 1 is provided with an accommodating groove 8 in which the support plate 2 is embedded, and the third magnet 5 is disposed on the accommodating groove 8. The above-described embedding includes partial embedding and full embedding, and is intended to be covered by the present application.

In the above, the third magnet 5 is arranged in a manner including, but not limited to, the following:

1. the third magnet 5 may be disposed in the accommodating groove 8 (e.g., the bottom wall of the accommodating groove 8);

2. the third magnet 5 may be disposed on a side of the base 1 facing away from the accommodating groove 8, such that the third magnet 5 cooperates with the first magnet 3 via a bottom wall of the accommodating groove 8.

Further, in the first state, the second magnet 4 and the fourth magnet 6 are in a vertical state. The magnetic attraction surfaces of the two are vertically arranged, so that the two have no magnetic attraction.

When the locking mechanism 7 is unlocked, the support plate 2 rotates around the rotation point of the support plate 2 to a under the action of thrust, and at the moment, the thrust and the suction are engaged. Finally, the magnetic attraction fit between the second magnet 4 and the fourth magnet 6 is realized to realize rotation limit. In the above description, the linking is defined as: the force with which the dominant support plate 2 rotates changes. For example, the support plate 2 is rotated by thrust force and then rotated by suction force, and the thrust force and the suction force have a connection relationship.

The application has a special technical effect that: when the locking mechanism 7 is unlocked, the support plate 2 is firstly changed from the first state to the second state under the action of the pushing force, the pushing force is gradually weakened along with the gradual rotation of the support plate 2 away from the base 1 (namely, the first magnet 3 is gradually away from the third magnet 5), and then the magnetic attraction between the second magnet 4 and the fourth magnet 6 is used for leading the driving of the support plate 2 to overturn.

Thus, the thrust and suction forces do not always coexist in the present application, but are generated sequentially. Such as when the support plate is in the first state, where only pushing force is present and no suction force is present. When the second magnet on the supporting plate is in ferromagnetic attraction fit with the fourth magnet, the supporting plate only has attraction force at the moment, and no thrust force exists.

On the visual effect brought by the whole product: the rotation of the support plate 2 is a process of first being fast (instantaneous thrust is large), then being slow (thrust is gradually weakened), and then being fast (generation of suction). The anti-magnetic rotation limiting structure is due to a special phenomenon. There is a different use experience and impressive technological sense for the consumer. In addition, since a deceleration link exists in the rotating process, the situation that the impact sound is too large or the magnets are damaged due to the fact that the kinetic energy is too large at the moment of the magnetic attraction of the fourth magnet 6 and the second magnet 4 finally does not occur.

Further, the supporting plate 2 and the base 1 can be connected through a rotating shaft 9. The rotating shaft 9 is: the support plate 2 rotates at a point. By reducing the coefficient of friction of the rotation between the support bar and the base 1 as much as possible, the generation of thrust and suction can be facilitated. Preferably, miniature bearings may be provided at both ends of the shaft 9 in an attempt to reduce the coefficient of friction. Or lubricating oil is smeared on the rotating shaft 9. This is prior art and the present application should cover these solutions.

Further, the wireless charger is preferably a MagSafe wireless charger.

In accordance with the nature of the present utility model, all wireless chargers having a first magnet 3 are intended to be included in the scope of the present application. The foregoing is merely illustrative to provide support.

Further, one end of the supporting plate 2, which is close to the base 1, is provided with a extension Shen Ban, and one side of the base 1 is provided with a notch 11 matched with the extension Shen Ban.

The second magnet 4 is disposed on the extension plate 10, and the fourth magnet 6 is disposed in the notch 11 of the base 1.

Further, when the lock mechanism 7 locks the support plate 2 in the first state, the thrust direction between the first magnet 3 and the third magnet 5 is set perpendicular to the support plate 2.

Further, when the second magnet 4 and the fourth magnet 6 are magnetically attracted and matched, the attraction direction between the second magnet 4 and the fourth magnet 6 is perpendicular to the direction of the supporting plate 2.

Further, in the present application, the locking mechanism 7 refers to all prior art with locking and unlocking functions that have been disclosed and which have been presented in the current date of the present application. Such as conventional deadbolt structures (mechanical structures common in the field of locks), or snap-in structures, limit structures, etc. This application includes, but is not limited to, the following examples:

1. the locking mechanism 7 includes a cam type rotary piece rotatably provided on the base 1, and when the support plate 2 is fitted into the accommodating groove 8, the cam type rotary piece is partially rotated to the upper end of the support plate 2 by rotating the cam type rotary piece, and a click is implemented to the upper end of the support plate 2 to achieve locking.

When the unlocking is needed, only the cam type rotary piece is required to be rotated again, so that the cam type rotary piece does not clamp the upper end of the support plate 2 any more, and at the moment, the thrust between the first magnet 3 and the third magnet 5 drives the support plate 2 to be converted from the first state to the second state.

2. The locking mechanism 7 comprises a dead bolt type structure. The following is detailed:

a clamping groove 12 is formed on the side edge of the supporting plate 2.

One side of the base 1 is provided with a control groove 13, and the control groove 13 and the accommodating groove 8 are mutually independent. The cell wall of holding tank 8 wears to be equipped with expansion plate 14, and the one end of expansion plate 14 can cooperate the joint with draw-in groove 12 on the backup pad 2 in holding tank 8, and the other end of expansion plate 14 is in control tank 13 and the butt has spring 15, and the other end of spring 15 cooperates with the cell wall of control tank 13. Under the action of the spring 15, the expansion plate 14 can extend into the accommodating groove 8 to be matched and clamped with the clamping groove 12 on the supporting plate 2.

The middle part of expansion plate 14 runs through and is provided with logical groove 16, and expansion plate 14 is provided with guide inclined plane 17 in logical inslot 16, is provided with spring bolt button 18 in the control groove 13, and spring bolt button 18 is provided with the pressure inclined plane 19 that matches with guide inclined plane 17 towards the one end of expansion plate 14. When the lock tongue button 18 is pressed by an external force, the pressing inclined surface 19 moves downwards and drives the expansion plate 14 to move towards the direction in which the spring 15 is pressed through the guiding inclined surface 17, so that the expansion plate 14 is gradually retracted into the control groove 13, and at the moment, one end of the expansion plate 14 is withdrawn from the clamping groove 12 at the side edge of the support plate 2, and the unlocking action is completed.

In addition, in order to facilitate the downward pressing and resetting of the dead bolt button 18, a guide rod 20 is provided on a side of the dead bolt button 18 facing the control groove 13, and a guide through hole 21 is also provided on the bottom wall of the control groove 13 to be matched with the guide rod 20. When the user releases the latch button 18, the spring 15 returns to the original state, and the push inclined surface 19 is pushed to push the latch button 18 upwards under the action of the guide inclined surface 17, so that the latch is reset.

The structure of the lock tongue is as follows! In this application, only for a simple explanation, to support the locking mechanism 7 in this application.

It is understood that the above solutions of the locking mechanisms 7 are all mechanical structures capable of providing locking and unlocking effects, and are within the scope of the present application. Modifications of the embodiments which do not creatively contribute to the utility model may be made by those skilled in the art after reading the present specification, but are protected by patent laws within the scope of the claims of the present utility model. The above list of locking mechanisms 7 is merely illustrative of the utility model and is not intended to be limiting.

Example 2:

the difference from example 1 is that: the receiving slot 8 serves as a storage compartment for storing articles. And the support plate 2 serves as a cover for opening and closing the storage chamber. This forms a conventional storage structure.

At this time, the magnetic type wireless charger is disposed on one side of the support plate 2 away from the base 1. When the cover closes the storage chamber, the magnetic wireless charger is arranged on the surface of the cover, so that a user can use the magnetic wireless charger normally.

From this, it can be seen that: the magnetic wireless charger can be selectively arranged on any side of the supporting plate 2 according to the use requirement. All of which are intended to fall within the scope of the present utility model.

Example 3:

the difference from example 1 is that:

when the support plate 2 is in the second state of being unfolded in rotation, the angle between the support plate 2 and the base 1 may be an acute angle or an obtuse angle.

In the above-described second state, the fourth magnet 6 and the second magnet 4 are magnetically engaged, so that the support plate 2 is subjected to the attraction force.

Therefore, in the second state of rotation and unfolding, the unfolding angle between the support plate 2 and the base can be adjusted according to the actual requirement, and the utility model also falls into the protection scope of the application.
