Fig. 1 to 5 are schematic structural views of the cartridge of the present embodiment. The box body is used for placing personal articles such as earphones, jewelry and the like, and is convenient to store and prevent from being lost. As shown in fig. 1 to 3, the box body includes a first casing 1 and a second casing 2 which are hinged, and the first casing 1 and the second casing 2 can relatively rotate to open or close the box body.
Specifically, the same side of the first casing 1 and the second casing 2 is hinged by a hinge shaft or the like, and the opposite side thereof is rotated to be opened or closed by the hinge shaft. The first housing 1 includes a first guide 3 and the second housing 2 includes a second guide 4, as shown in fig. 1 to 3. One end of the first guide 3 is fixedly connected to the inside of the first housing 1, and the other end extends toward the second housing 2, as shown in fig. 4. One end of the second guide 4 is fixedly connected to the inside of the second housing 2, and the other end extends toward the first housing 1, as shown in fig. 5. In the present embodiment, the first guide 3 and the second guide 4 are disposed at positions such that they can slide relative to each other with the rotation of the first housing 1 and the second housing 2, and no interference occurs between them.
The box body further comprises a first magnetic member 5 and a second magnetic member 6, as shown in fig. 1-5. The first magnetic member 5 is fixedly connected with the first guide member 3, the second magnetic member 6 is fixedly connected with the second guide member 4, and when the first guide member 3 and the second guide member 4 slide relatively, interference between the first magnetic member 5 and the second magnetic member 6 cannot be generated. That is, first casing 1, first guide 3 and first magnetic force piece 5 fixed connection are as an organic whole, and second casing 2, second guide 4 and second magnetic force piece 6 fixed connection are as an organic whole, and this makes first casing 1 and second casing 2 at the in-process that opens and shuts, and first magnetic force piece 5 and second magnetic force piece 6 do not have relative friction or contact motion respectively with other structures between, can avoid producing the noise.
Specifically, the first magnetic member 5 is close to the outer end of the first guide member 3, and the second magnetic member 6 is close to the outer end of the second guide member 4. The magnetic pole of the first magnetic member 5 close to the outer end of the first guide member 3 is the same as the magnetic pole of the second magnetic member 6 close to the outer end of the second guide member 4, and the magnetic pole of the first magnetic member 5 far away from the outer end of the first guide member 3 is the same as the magnetic pole of the second magnetic member 6 far away from the outer end of the second guide member 4.
In this embodiment, the magnetic pole of the first magnetic member 5 near the outer end of the first guide member 3 and the magnetic pole of the second magnetic member 6 near the outer end of the second guide member 4 are both south poles, and the magnetic pole of the first magnetic member 5 far from the outer end of the first guide member 3 and the magnetic pole of the second magnetic member 6 far from the outer end of the second guide member 4 are both north poles, as shown in fig. 1-3. In other alternatives, the magnetic poles on both sides of the first magnetic member 5 and the magnetic poles on both sides of the second magnetic member 6 may be arranged in a reverse manner to the above-described embodiment, that is, the magnetic poles on the side of the first magnetic member 5 near the outer end of the first guide member 3 and the magnetic poles on the side of the second magnetic member 6 near the outer end of the second guide member 4 are both north poles.
When the cartridge is in the fully open state, the first casing 1 and the second casing 2 are located at the third position, as shown in fig. 3. The area where the first guide member 3 and the second guide member 4 cross in the height direction is smallest, and the first magnetic member 5 is located above the second magnetic member 6 as shown in fig. 3. The south pole of the first magnetic member 5 and the south pole of the second magnetic member 6 are opposite (homopolar opposite), and the first magnetic member 5 and the second magnetic member 6 repel each other and are subjected to opposite forces, so that the integral structure formed by the first housing 1, the first guide member 3 and the first magnetic member 5 is subjected to an upward force, and the integral structure formed by the second housing 2, the second guide member 4 and the second magnetic member 6 is subjected to a downward force. Therefore, the first shell 1 and the second shell 2 of the box body have certain retaining force respectively, and the first shell 1 and the second shell 2 are prevented from shaking randomly to cause the box body to be closed.
The process of closing the box body from the opening state to the closing state is as follows:
(1) during the closing process of the box body, the first magnetic member 5 moves towards the direction close to the second shell 2, and the second magnetic member 6 moves towards the direction close to the first shell 1. Before the first magnetic member 5 and the second magnetic member 6 move to the second position, the first magnetic member 5 is located above the second magnetic member 6, and the first magnetic member 5 and the second magnetic member 6 always keep repulsive force, that is, the integral structure formed by the first housing 1, the first guide member 3 and the first magnetic member 5 always receives upward force, and the integral structure formed by the second housing 2, the second guide member 4 and the second magnetic member 6 always receives downward force. At this time, a user is required to apply an external force to the box body to overcome the repulsive force, so that the first housing 1 drives the first guide member 3 and the first magnetic member 5 to turn over to a side close to the second housing 2. The direction of the arrow shown in fig. 3 is the direction of the force application. The second position is a position where the magnetic lines of force of the first magnetic member 5 and the magnetic lines of force of the second magnetic member 6 are balanced by vector superposition.
(2) When the first magnetic member 5 and the second magnetic member 6 move from the third position to the second position, the magnetic lines of force of the first magnetic member 5 and the magnetic lines of force of the second magnetic member 6 are vector-superposed, and at this time, the magnetic lines of force can be vector-superposed and balanced, and the first housing 1 and the second housing 2 can be stopped and kept still at this point under the condition of not being subjected to external force, so that the first housing 1 and the second housing 2 are in a half-open state, as shown in fig. 2.
(3) When the first magnetic member 5 and the second magnetic member 6 continue to move from the second position to the first position, and the first magnetic member 5 is located below the second magnetic member 6, the other two opposite poles (two opposite poles) of the first magnetic member 5 and the second magnetic member 6 are opposite to each other, and the first magnetic member 5 and the second magnetic member 6 repel each other and receive opposite forces, so that the overall structure formed by the first casing 1, the first guide member 3 and the first magnetic member 5 receives a downward force, and the overall structure formed by the second casing 2, the second guide member 4 and the second magnetic member 6 receives an upward force, so that the first casing 1 and the second casing 2 automatically close under the action of the repulsive force, as shown in fig. 1.
When the box body is in a closed state, the crossed area of the first guide part 3 and the second guide part 4 along the height direction is the largest, and the first magnetic part 5 is positioned below the second magnetic part 6. The north pole of the first magnetic member 5 is opposite to the north pole of the second magnetic member 6 (opposite to the same pole), and the first magnetic member 5 and the second magnetic member 6 repel each other and are subjected to opposite forces, so that the overall structure formed by the first housing 1, the first guide member 3 and the first magnetic member 5 is subjected to a downward force, and the overall structure formed by the second housing 2, the second guide member 4 and the second magnetic member 6 is subjected to an upward force. Therefore, the first shell 1 and the second shell 2 of the box body respectively have certain holding force, and the relative positions of the first shell 1 and the second shell 2 when the first shell 1 and the second shell 2 are closed are maintained.
The process of opening the box body from the closed state to the open state of the box body in the embodiment is completely opposite to the process of closing the box body from the open state to the closed state, and other functions are not changed and are not described herein again.
The first guide piece 3 and the second guide piece 4 are integrally of an arc-shaped structure, the rotating central axis of the first guide piece 3 and the rotating central axis of the second guide piece 4 are both identical to the hinged central axis of the first shell 1 and the second shell 2, namely the rotating central axes of the first guide piece 3 and the second guide piece 4 are identical, and effective rotation between the first shell 1 and the second shell 2 can be realized.
In a preferred embodiment, the first guide member 3 and the second guide member 4 are arc-shaped structures having tubular passages, the distance from the arc-shaped center line of the tubular passage of the first guide member 3 to the hinge central axis (the hinge central axis of the first housing 1 and the second housing 2) is the same as the distance from the arc-shaped center line of the tubular passage of the second guide member 4 to the hinge central axis, and the outer diameter of the second guide member 4 is smaller than the inner diameter of the tubular passage of the first guide member 3 so that the second guide member 4 slides within the tubular passage of the first guide member 3. Therefore, the first shell 1 drives the first guide piece 3 to rotate relative to the second shell 2 and the second guide piece 4 respectively, so that the first guide piece 3 and the second guide piece 4 do not interfere with each other when rotating, and the box body can realize a good opening and closing function.
Further, the first magnetic member 5 is annular, the first magnetic member 5 is sleeved outside the first guide member 3, and the second magnetic member 6 is fixedly disposed in the tubular passage of the second guide member 4. In the opening and closing process of the first housing 1 and the second housing 2, when the first housing 1 and the second housing 2 are at the first position and the third position, the first housing 1 and the second housing 2 can respectively obtain a repulsive force which is relatively balanced, so that the first housing 1 and the second housing 2 can move towards a preset direction due to the repulsive force, and the opening state and the closing state of the box body can be kept, the housings can be automatically opened, and the like. The second position is that when the second magnetic member 6 penetrates into the annular middle position of the first magnetic member 5, the magnetic lines of force of the second magnetic member and the first magnetic member are vector-superposed, at the moment, the magnetic force is relatively balanced, and the positions of the first shell 1 and the second shell 2 are not kept unchanged by external force. The first magnetic member 5 may be non-circular, and the first magnetic member 5 may be disposed outside the first guide 3. When the second magnetic member 6 moves to the same radial direction as the first magnetic member 5, the magnetic forces of the two are balanced relatively, and the first housing 1 and the second housing 2 are not held by external force.
In another preferred embodiment, the relative positions of the first guide member 3 and the second guide member 4 are reversed, and the inner diameter of the tubular channel of the second guide member 4 is larger than the outer diameter of the first guide member 3 so that the first guide member 3 slides within the tubular channel of the second guide member 4. The second magnetic member 6 is annular, the second magnetic member 6 is sleeved outside the second guide member 4, and the first magnetic member 5 is fixedly arranged in the tubular passage of the first guide member 3. The second magnetic member 6 may be configured in a non-circular ring shape, and the second magnetic member 6 is disposed outside the second guide 4. When the second magnetic member 6 moves to the same radial direction as the first magnetic member 5, the magnetic forces of the two are balanced relatively, and the first housing 1 and the second housing 2 are not held by external force.

The magnetic parts are fixed in the grooves of the guide parts with small cross section sizes, the magnetic parts are fixed on the outer side faces of the guide parts with large cross section sizes, the magnetic poles of the two magnetic parts close to one side of the outer end of the corresponding guide part are the same, and the magnetic poles far away from one side of the outer end of the corresponding guide part are the same. The shape of the magnetic member can be specifically set according to requirements, and is not limited to a circular ring shape, a non-circular ring shape and the like, and the two magnetic members are arranged so as not to interfere with each other when sliding relatively and can realize the functions of the embodiment.
In other embodiments, the first guide 3 and the second guide 4 may be provided in a circular arc structure in which a rotation central axis of the first guide 3 and a rotation central axis of the second guide 4 are hinge central axes of the first housing 1 and the second housing 2. Specifically, the radius of the first guide 3 is larger or smaller than that of the second guide 4, so that the first guide 3 is located outside or inside the second guide 4, and the relative sliding between the two does not interfere with each other. The first magnetic member 5 and the second magnetic member 6 are respectively arranged on two sides which do not interfere with each other when the first guide member 3 and the second guide member 4 slide. Namely, when the first guide member 3 is positioned outside the second guide member 4, the first magnetic member 5 is disposed on the radially outer side surface of the first guide member 3, and the second magnetic member 6 is disposed on the radially inner side surface of the second guide member 4; when the first guide member 3 is located inside the second guide member 4, the first magnetic member 5 is disposed on a radially inner side surface of the first guide member 3, and the second magnetic member 6 is disposed on a radially outer side surface of the second guide member 4.
