When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1, 2 and 3, a storage box 10 according to an embodiment of the present invention may be used for storing wireless earphones and other objects, and the storage box 10 includes a box body 100, a cover 200, a key 300, a first magnetic member 410, a second magnetic member 420, a third magnetic member 430, a first elastic member 510 and a second elastic member 520. The box 100 is provided with a receiving cavity 150 for receiving objects, and the cover 200 is rotatably connected to the box 100 such that the cover 200 can cover or open the receiving cavity 150, and it can also be understood that the cover 200 covers or opens the box 100. The first elastic member 510 is coupled between the case 100 and the cover 200. Both the second magnetic member 420 and the third magnetic member 430 are fixed on the key 300, so that the second magnetic member 420, the third magnetic member 430 and the key 300 can be regarded as a whole, one of the box 100 and the cover 200 is provided with the key 300 and the other is provided with the first magnetic member 410. For example, the key 300 is disposed on the case 100, and the first magnetic member 410 is disposed on the cover 200. In other embodiments, the key 300 may be disposed on the cover 200, and the first magnetic element 410 is disposed on the box 100.

In some embodiments, the first elastic element 510 may be a spiral spring, and during the process that the cover 200 rotates close to the box 100 to cover the accommodating cavity 150, the cover 200 overcomes the elastic force of the first elastic element 510, so that the first elastic element 510 stores energy. In the process of rotating the cover 200 away from the box 100 to open the accommodating cavity 150, the first elastic member 510 releases energy, so as to assist the rotation of the cover 200 relative to the box 100 to push.

Referring to fig. 1, 2, 4 and 5, in some embodiments, the box 100 includes a body 110, a supporting plate 120, a post 130 and a limiting member 140. The main body 110 encloses a receiving cavity 150, and the supporting plate 120, the protruding column 130 and the limiting member 140 can be disposed in the receiving cavity 150. The body portion 110 includes an inner layer 112 and an outer layer 113, the outer layer 113 is sleeved outside the inner layer 112, so that the outer layer 113 is disposed around the inner layer 112, and the inner layer 112 encloses the accommodating cavity 150. The roughness of the outer layer 113 may be greater than the roughness of the inner layer 112, for example, the outer layer 113 may be made of a rubber material, i.e., the outer layer 113 is a rubber layer. Considering that the roughness and the softness of outer layer 113 are relatively great, that is, the surface of outer layer 113 is not smooth, when the user grips receiver 10, the user will contact with outer layer 113, can improve the frictional force between user and outer layer 113, avoid outer layer 113 to take place the condition of slippage because of the surface is too smooth, also can improve the comfort level that the user gripped receiver 10.

The inner layer 112 may be a composite layer, for example, the inner layer 112 includes three layers, which are respectively denoted as a heat insulation layer 1121, a wear-resistant layer 1122, and a shielding layer 1123, the heat insulation layer 1121 is closest to the outer layer 113, the shielding layer 1123 surrounds the accommodating cavity 150, and the wear-resistant layer 1122 is sleeved between the heat insulation layer 1121 and the shielding layer 1123. In short, the thermal insulation layer 1121, the wear-resistant layer 1122, and the shielding layer 1123 are sequentially disposed in an outward-inward direction. By providing the inner layer 112, it is effectively prevented that external heat and electromagnetic waves interfere with wireless earphones and other objects accommodated in the accommodating chamber 150.

In some embodiments, the body portion 110 may be formed with a sliding slot 111, and the sliding slot 111 may be a semi-circle; the limiting member 140 is fixedly connected to the main body 110, and a limiting groove 141 may be formed on the limiting member 140, and the limiting groove 141 may be rectangular. The supporting plate 120 is fixedly connected with the body part 110. The key 300 includes a pressing portion 311 and a guiding portion 312 connected to each other, and the pressing portion 311 and the guiding portion 312 can be connected by adhesive bonding, so that the key 300 is formed by separate bodies, but the key 300 can also be manufactured by integral forming. The cross-sectional dimension of the pressing part 311 is larger than that of the guide part 312, and the pressing part 311 is in sliding fit with the sliding groove 111, so that the cross section of the pressing part 311 is semicircular; the guide portion 312 is slidably fitted with the stopper groove 141 and may be carried on the support plate 120 such that the guide portion 312 has a rectangular cross section. When a force is applied to the pressing portion 311, the pressing portion 311 slides in the sliding slot 111, and the guiding portion 312 slides in the limiting slot 141, so that the key 300 and the case 100 are finally in a sliding connection. In other embodiments, the key 300 may be rotatably connected to the case 100.

The supporting plate 120 may be horizontally disposed, the lower end of the protruding pillar 130 is a fixed end and is connected to the supporting plate 120, and the upper end of the protruding pillar 130 is a free end and is set to a length toward the protruding pillar 130 of the cover body 200 with respect to the supporting plate 120, that is, the protruding pillar 130 is vertically disposed. The second elastic member 520 may be a spring, and the second elastic member 520 is pressed between the key 300 and the case 100, for example, one end of the second elastic member 520 is pressed against the convex pillar 130 of the case 100, and the other end of the second elastic member 520 is pressed against the guiding portion 312 of the key 300. When a user applies a pressing force to the pressing portion 311 toward the accommodating cavity 150, the entire key 300 slides inward relative to the box 100, and at this time, the key 300 applies a pressing force to the second elastic member 520, so that the second elastic member 520 stores energy. When the user releases the pressing force, the second elastic member 520 releases energy, so that the second elastic member 520 pushes the key 300 to move outward and automatically reset, and the second elastic member 520 can perform a reset function on the key 300.

In some embodiments, the cover 200 has a first groove 210 formed thereon, and the first magnetic element 410 is matched with the first groove 210, which can be understood as the first magnetic element 410 embedded in the cover 200. The surface of the first magnetic member 410, which is located at the end of the first magnetic member 410 and is disposed toward the case 100, is located outside the first groove 210, and the surface of the cover 200 may be flush with each other or may be spaced apart from the surface of the cover 200 in the thickness direction of the entire storage case 10.

In some embodiments, the key 300 is provided with a second groove 320 and a third groove 330, the second groove 320 and the third groove 330 are disposed at intervals, and the second magnetic element 420 is matched with the second groove 320, which can be understood as that the second magnetic element 420 is embedded in the key 300. The surface of the second magnetic member 420 facing the cover 200 is located outside the second groove 320, and the surface of the key 300 may be flush with each other, or may be spaced from the surface of the key 300 along the thickness direction of the entire storage case 10. The third magnetic element 430 is matched with the third groove 330, and it can be understood that the third magnetic element 430 is embedded in the key 300. The surface of the third magnetic member 430, which is located at the end of the third magnetic member 430 and faces the cover 200, is located outside the third groove 330, and the surface of the key 300 may be flush with each other, or may be spaced from the surface of the key 300 along the thickness direction of the entire storage case 10.

Referring to fig. 1, 2 and 3, the first magnetic member 410, the second magnetic member 420 and the third magnetic member 430 may be bar magnets, and the magnetic poles of the first magnetic member 410 adjacent to the box 100 are opposite to the magnetic poles of the second magnetic member 420 adjacent to the cover 200, so that an attractive force is generated between the first magnetic member 410 and the second magnetic member 420. The magnetic poles of the first magnetic member 410 disposed near the case 100 and the magnetic poles of the third magnetic member 430 disposed near the cover 200 have the same polarity, so that a repulsive force is generated between the first magnetic member 410 and the third magnetic member 430. For example, when the magnetic pole of the first magnetic member 410 disposed near the case 100 is an S pole, the magnetic pole of the second magnetic member 420 disposed near the cover 200 is an N pole, and the magnetic pole of the third magnetic member 430 disposed near the cover 200 is an S pole. For another example, when the magnetic pole of the first magnetic member 410 close to the case 100 is an N pole, the magnetic pole of the second magnetic member 420 close to the cover 200 is an S pole, and the magnetic pole of the third magnetic member 430 close to the cover 200 is an N pole.

Since the key 300 is slidably disposed on the box 100 and both the second magnetic member 420 and the third magnetic member 430 are fixed on the key 300, both the second magnetic member 420 and the third magnetic member 430 can follow the key 300 to move relative to the box 100. The two positions where the key 300 slides relative to the case 100 are referred to as a first position and a second position, and when the key 300 is located at the first position and the case 100 is closed by the cover 200, the first magnetic member 410 and the second magnetic member 420 contact each other, so that an attractive force is generated between the first magnetic member 410 and the second magnetic member 420, thereby fixing the cover 200 and improving the stability and reliability of the cover 200 closed on the case 100. When the user presses the key 300 to move the key 300 from the first position to the second position while the cover 200 covers the case 100, the second magnetic member 420 is out of contact with the first magnetic member 410, so that the third magnetic member 430 is in contact with the first magnetic member 410, and the third magnetic member 430 generates a repulsive force to the first magnetic member 410, so that the cover 200 rotates away from the case 100, and at the same time, the first elastic member 510 releases energy and further pushes the cover 200 to rotate away from the case 100, and under the combined action of the repulsive force between the third magnetic member 430 and the first magnetic member 410 and the elastic force of the first elastic member 510, the cover 200 can automatically and rapidly rotate away from the case 100, and finally the cover 200 opens the case 100, so as to achieve the storage of the objects in the case 100. When the user releases the pressing force after the cover 200 opens the box 100, the second elastic member 520 releases the releasing ability, so that the second elastic member 520 pushes the key 300 to automatically return from the second position to the first position.

In some embodiments, the cross-sectional dimension of the second magnetic member 420 is greater than the cross-sectional dimensions of both the first and third magnetic members 410 and 430. Therefore, the second magnetic member 420 has a relatively large contact area, so that the second magnetic member 420 has a large magnetic attraction force, and on the other hand, when the key 300 is in the first position, the first magnetic member 410 and the second magnetic member 420 can be effectively ensured to form a reliable contact relationship, so that the first magnetic member 410 and the second magnetic member 420 can have a sufficiently large attraction force, so that the cover 200 can be stably and reliably covered on the case 100.

The working principle of the storage box 10 is described below:

when the cover 200 is opened to the case 100, the button 300 is at the first position, and when the cover 200 needs to cover the case 100, the cover 200 can be rotated close to the case 100, so that the first elastic member 510 stores energy, i.e. the cover 200 overcomes the elastic force of the first elastic member 510 to rotate close to the case 100, and when the first magnetic member and the second magnetic member 420 are in contact with each other, the first magnetic member and the second magnetic member will generate attraction force, so that the cover 200 can be stably covered on the case 100.

When the cover 200 needs to be opened, a pressing force can be applied to the key 300, so that the key 300 moves from the first position to the second position against the elastic force of the second elastic member 520, at this time, the first magnetic member 410 and the second magnetic member 420 are separated, so that the third magnetic member 430 contacts with the first magnetic member 410, the third magnetic member 430 generates a repulsive force to the first magnetic member 410, so that the cover 200 generates an initial acceleration for rotating away from the box 100, and at the same time, the first elastic member 510 releases energy, thereby ensuring that the cover 200 automatically rotates away from the box 100 to open the box 100. When the cover 200 opens the case 100 and the pressing force is removed, the second elastic member 520 pushes the button 300 to return to the first position automatically to reset under the action of the second elastic member 520 releasing energy.

If the cover 200 covers the box 100, the cover 200 is fastened to the box 100 by a snap-fit mechanism, a mechanical mechanism, an electric motor or a solenoid lock, so that the storage box 10 has more parts, which results in a complex structure of the storage box 10 and increases the manufacturing cost of the storage box; secondly, the volume of the storage box 10 can be increased, which is not beneficial to the miniaturization design of the storage box 10, thereby being not beneficial to the carrying of the storage box 10. Thirdly, the mechanism will be prone to failure, affecting the service life of the storage box 10.

With the storage box 10 of the above embodiment, when the key 300 is at the first position, the first magnetic member 410 and the second magnetic member 420 generate an attractive force, so as to stably fix the cover 200 to the box 100. When the key 300 is moved from the first position to the second position, the third magnetic member 430 will repel the first magnetic member 410, and the first elastic member 510 releases energy, so that the cover 200 automatically opens the box 100. Therefore, the number of parts of the storage case 10 is greatly reduced, so that the structure of the storage case is simplified, the manufacturing cost of the storage case 10 is reduced, the volume of the storage case 10 is reduced to realize a compact design, and the storage case 10 is conveniently carried. And receiver 10 is difficult to mechanical failure, has improved receiver 10's life.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
