As shown in FIG. 1, in some embodiments, a cavity 110 may also be provided in the box cover 100. After the box cover 100 is closed with the box body 200, the cavity 211 and the cavity 110 can communicate, thereby increasing the storage capacity. Space for items.

Fig. 2 is a schematic structural view of the box cover 100 in Fig. 1. As shown in Figs. 1 and 2, the box cover 100 includes a cover portion 111 and an extension portion 112. The upper dashed frame in Fig. 2 is the cover portion 111. The extension 112 is in the dashed frame below. The cover portion 111 is used to cover the opening 210 of the box body 200. The extension portion 112 extends from the rotating connection portion 300 of the box cover 100 and the box body 200. As shown in FIG. 1, at least a part of the extension portion 112 extends into the cavity 211. Since the extension portion 112 and the cover portion 111 are fixedly connected or integrally formed, the extension portion 112 and the cover portion 111 move synchronously.

In one of the embodiments, as shown in FIGS. 1 and 2, the box cover 100 is provided with a first magnetic member 11. The first magnetic member 11 may be a permanent magnet, such as a magnet; for another example, the first magnetic member 11 may also be an electromagnet, and the electromagnet needs to be energized before it has magnetism. As shown in FIGS. 1 and 2, the first magnetic member 11 may be completely disposed on the extension portion 112. In other embodiments, one part of the first magnetic member 11 may be arranged on the extension part 112 and another part on the cover part 111. In other words, at least a part of the first magnetic member 11 is provided on the extension portion 112.

In the bar magnet, the direction of the magnetic line of force inside the magnet is from the S pole to the N pole. As shown in FIG. 2, the first magnetic member 11 may be a bar magnet, and the direction of the magnetic line of induction inside the first magnetic member 11 may be horizontal to the right.

As shown in FIG. 1, a second magnetic member 12 is provided in the box 200. The second magnetic member 12 may also be a permanent magnet or an electromagnet. The second magnetic member 12 is a bar-shaped permanent magnet as an example for description. As shown in FIG. 1, the second magnetic member 12 is provided in the box body 200. Specifically, it can be provided in the cavity 211 of the box body 200. Of course, it is not limited to all the second magnetic members 12 being provided in the cavity 211, or the second magnetic member 12 The two magnetic parts 12 are partially disposed in the cavity 211. As shown in FIG. 1, during the opening process of the box cover 100 and the box body 200, the extension portion 112 makes a circular arc movement with the rotating connecting portion 300 as the center. The second magnetic member 12 is arranged outside the track where the extension 112 rotates around the rotating connecting portion 300 as the center, that is, the second magnetic member 12 does not prevent the box body 200 and the box cover 100 from opening. When the lid 100 and the box body 200 are closed from the lid to the opening process, after the lid 111 and the box body 200 are opened at a certain angle, the magnetic field force between the first magnetic member 11 and the second magnetic member 12 drives the box lid 100 and The box 200 is opened. For example, when the lid 100 and the box body 200 are closed to open, when the opening angle is between 0° and 45°, the magnetic field force between the first magnetic member 11 and the second magnetic member 12 will not The box cover 100 and the box body 200 are driven to open; after the opening angle is greater than 45°, the magnetic field force between the first magnetic member 11 and the second magnetic member 12 drives the box cover 100 and the box body 200 to open, and the box cover 100 is opened by hand. After opening to the box body 200 to an angle greater than 45°, it can be felt that there is a force between the box cover 100 and the box body 200 to push the box cover 100 and the box body 200 to open.

In the bar magnet, the direction of the magnetic line of force inside the magnet is from the S pole to the N pole. As shown in FIG. 3, the second magnetic member 12 may be a bar magnet, and the direction of the magnetic line of induction inside the second magnetic member 12 may be in the vertical direction.

As shown in (a) and (b) of FIG. 4, they are partial structural diagrams of the box body 200 in the two embodiments, and the plane where the opening 210 of the box body 200 is roughly located is t. As shown in Fig. 4(a), the angle β between the direction of the magnetic line of force inside the second magnetic member 12 and the plane t is 80°. As shown in Fig. 4(b), the angle β between the direction of the magnetic line of force inside the second magnetic member 12 and the plane t is 100°. In other embodiments, 80°≤β≤100°. That is to say, in FIG. 3, the direction of the magnetic line of force inside the second magnetic member 12 may be along the vertical direction, and on the basis of FIG. 3, the direction of the magnetic line of force inside the second magnetic member 12 may be left or right. Each offset 10° or any angle within 10°. This angle can better ensure that the magnetic field force of the product between the first magnetic member 11 and the second magnetic member 12 is sufficiently large, so that the lid 100 and the box body 200 are closed from the lid to the opening process, and the lid 111 interacts with each other. After the box body 200 is opened at a certain angle, the magnetic field force between the first magnetic member 11 and the second magnetic member 12 drives the box cover 100 and the box body 200 to open.

As shown in FIG. 5, FIG. 5 is a schematic diagram of the box in an embodiment of the application from the closed state to the open state. The line where the magnetic line of induction inside the first magnetic member 11 is located is the dashed line m1, and the line where the line of magnetic induction inside the second magnetic member 12 is located is the dashed line m2. As shown in Figure 5, when the box is closed from the lid to the open state, it goes through successively that m1 is perpendicular to m2, the acute angle between m1 and m2 gradually decreases, m1 and m2 are parallel, and the acute angle between m1 and m2 gradually increases. The big process. In other words, the process of closing the lid 100 and the box body 200 from the lid to opening includes at least the process of the magnetic lines of induction within the first magnetic member 11 and the second magnetic member 12 from being perpendicular to parallel. In other words, the process of closing the lid 100 and the box body 200 from the lid to opening includes at least the process of the magnetic lines of induction within the first magnetic member 11 and the second magnetic member 12 from being parallel to intersecting again.

In one of the embodiments, as shown in FIGS. 1 and 2, of the two magnetic poles of the first magnetic member 11, the left side is the S pole and the right side is the N pole; of the two magnetic poles of the second magnetic member 12, The upper side is the S pole, and the lower side is the N pole. When the box is closed to open, the position of the second magnetic member 12 relative to the box does not change. Therefore, the direction of the magnetic line of force inside the second magnetic member 12 is always from the S pole to the N pole. In the embodiment shown in FIG. 1 or FIG. 2, the direction of the magnetic lines of induction inside the second magnetic member 12 is directed from top to bottom. In the embodiment shown in FIG. 1, when the box cover is closed, the direction of the magnetic line of induction inside the first magnetic member 11 is from left to right. As shown in FIG. 5, as the box cover 100 is opened, the first magnetic member The direction of the magnetic line of induction inside 11 is also changing. During a process of opening, as shown in Figure 5(3), the direction of the magnetic line of induction inside the first magnetic member 11 is pointing upwards, that is, the box When the cover 100 rotates until the inner magnetic lines of the first magnetic element 11 and the second magnetic element 12 are parallel, the directions of the inner magnetic lines of the first magnetic element 11 and the second magnetic element 12 are opposite. In other embodiments, for example, as shown in FIG. 4, the angle between the direction of the magnetic line of force inside the second magnetic element 12 and the plane t is β, 80°≤β≤100°, although the value of β is different , But during the whole process of opening the box cover 100, as long as the box cover 100 rotates to the first magnetic part 11 and the second magnetic part 12 internal magnetic lines parallel, the first magnetic part 11 and the second magnetic part 12 internal magnetic induction The directions of the lines are all opposite. For another example, among the two magnetic poles of the first magnetic member 11, when the left side is the N pole and the right side is the S pole, correspondingly, of the two magnetic poles of the second magnetic member 12, the upper side is the N pole, and the lower side It is the S pole. In this embodiment, when the box cover 100 is rotated to the first magnetic member 11 and the second magnetic member 12, when the inner magnetic lines are parallel, the direction of the first magnetic member 11 and the second magnetic member 12 The opposite is also true. In the embodiment shown in FIG. 1, when the box cover 100 is closed, the magnetic pole on the right side of the first magnetic member 11 is closer to the second magnetic member 12, and the magnetic pole on the right side of the first magnetic member 11 is closer to the second magnetic member 12. The magnetic poles on the lower side are the same. In the above embodiment, when the magnetic poles are arranged in this way, the lid 100 and the box 200 are closed from the lid to the opening process. After the lid 111 and the box 200 are opened at a certain angle, the first magnetic member 11 and the second magnetic The magnetic field force between the pieces 12 drives the box cover 100 and the box body 200 to open. For example, when the lid 100 and the box body 200 are closed to open, when the opening angle is between 0° and 45°, the magnetic field force between the first magnetic member 11 and the second magnetic member 12 will not The box cover 100 and the box body 200 are driven to open; after the opening angle is greater than 45°, the magnetic field force between the first magnetic member 11 and the second magnetic member 12 drives the box cover 100 and the box body 200 to open, and the box cover 100 is opened by hand. After opening to the box body 200 to an angle greater than 45°, it can be felt that there is a force between the box cover 100 and the box body 200 to push the box cover 100 and the box body 200 to open.

In one of the embodiments, as shown in FIG. 1, the second magnetic member 12 includes a first end 12A close to the opening 210 of the box body 200 and a second end 12B extending into the box body 200. The distance h1 between the rotating connecting portion 300 and the first end 12A is smaller than the distance h2 between the rotating connecting portion 300 and the second end 12B. In other words, the second magnetic member 12 has an intermediate surface t along the vertical direction. In the embodiment shown in FIG. 1, the rotating connecting portion 300 is disposed on the upper portion of the intermediate surface t. As shown in Figure 5(3), when the internal magnetic lines of induction of the first magnetic member 11 and the second magnetic member 12 are parallel, then the first magnetic member 11 is closer to the first end 12A to generate greater magnetic field force At this time, the magnetic field force between the first magnetic member 11 and the second magnetic member 12 can continue to open the box cover 100.

Continuing to refer to FIG. 1, the distance h3 from the rotating connecting portion 300 to the opening 210 is greater than the distance h4 from the first end 12A to the opening 210. In other words, the actual position of the rotating connecting portion 300 is between the first end 12A and the intermediate surface t. As shown in FIG. 5(3), the box cover 100 is opened to the state shown in FIG. 5(3). After that, you can continue to open to the state shown in Figure 5 (4).

Finally, the first magnetic member 11 abuts on the third magnetic member 13, which is the final posture in which the box cover 100 is opened at this time.

As shown in FIG. 6, the length h6 of the extension portion 112 is greater than the shortest distance h5 between the third magnetic member 13 and the rotating connection portion 300. Since the first magnetic member 11 is disposed on the extension 112, by reasonably selecting the position of the first magnetic member 11 on the extension 112, when the box cover 100 is fully opened, the first magnetic member 11 disposed on the extension 112 can be After abutting against the third magnetic member 13 and the box cover 100 is fully opened, since the first magnetic member 11 can abut against the third magnetic member 13, the box cover 100 can be kept in a stable open state.

After the angle, the magnetic field generated by the magnetic unit and the magnetic field force generated by the first magnetic member 11 drive the box cover 100 to move in the direction of opening the box. During this process, if the box cover 100 is opened with both hands, for example, one hand holds the box body 200 and the other hand holds the box cover 100, in the process of opening the lid, after opening a certain angle, you can clearly feel There is a pushing force between the box cover 100 and the box body 200 to push the box cover 100 and the box body 200 to open.
