Referring to fig. 1 and 2, in one embodiment, a protective case 10 is provided for housing an electronic device. The protective case 10 includes an upper cover 100, a first lower cover 210, and a second lower cover 220. The first lower cover 210 and the second lower cover 220 are movably disposed on two opposite sides of the upper cover 100, respectively, and the first lower cover 210 and the second lower cover 220 are detachably connected to cooperate with the upper cover 100 to wrap the electronic device. When a user wants to install the protective case 10 on an electronic device, the user can hold the two opposite sides of the upper cover 100, which are provided with the first lower cover 210 and the second lower cover 220, with a hand, place the electronic device on the upper cover 100 and between the first lower cover 210 and the second lower cover 220, and then connect the first lower cover 210 and the second lower cover 220 to wrap the electronic device, thereby protecting the electronic device. When the protective case 10 is used for enclosing and wrapping the electronic device, the hand of the user is not located at the closed position, that is, is not located at the joint of the first lower cover 210 and the second lower cover 220, so that the hand of the user can be prevented from being clamped in the cover closing process, and better use experience is brought to the user.

Referring to fig. 2, the first lower cover 210 and the second lower cover 220 may be respectively rotatably connected to opposite sides of the upper cover 100, and the first lower cover 210 may be detachably connected to the second lower cover 220 by a magnetic attraction manner.

For example, in the embodiment shown in fig. 2, the upper cover 100 is opened with a receiving groove 101, and the receiving groove 101 can carry and fix the electronic device. Therefore, when the user installs the electronic device, the electronic device may be first placed in the receiving groove 101 of the upper cover 100 to fix the electronic device, and then the first lower cover 210 and the second lower cover 220 are rotated relative to the upper cover 100 until the first lower cover 210 and the second lower cover 220 are magnetically connected, and the electronic device is wrapped by the first lower cover 210, the second lower cover 220 and the upper cover 100. The first lower cover 210 and the second lower cover 220 are magnetically connected, so that the user can conveniently detach and install the first lower cover.

Further, in the embodiment shown in fig. 3, the protective case 10 further includes a first flexible member 410 and a second flexible member 420. The material for making the first flexible member 410 and the second flexible member 420 may include, but is not limited to, leather, cloth, silicone, and rubber.

The first flexible member 410 and the second flexible member 420 are disposed on two opposite sides of the upper cover 100, the first lower cover 210 is rotatably connected to one side edge of the upper cover 100 through the first flexible member 410, and the second lower cover 220 is rotatably connected to the other side edge of the upper cover through the second flexible member 420. The first flexible member 410 and the second flexible member 420 extend along the length direction L of the upper cover 100 at the edge of the upper cover 100, so that the connection area between the first flexible member 410 and the second flexible member 420 and the upper cover 100 is increased. The first flexible member 410 further extends along the length direction L of the first lower cover 210 at the connection position with the first lower cover 210, thereby increasing the connection area of the first flexible member 410 and the first lower cover 210; the second flexible member 420 also extends along the length direction L of the second lower cover 220 at the connection position with the second lower cover 220, thereby increasing the connection area of the second flexible member 420 and the second lower cover 220. Such a structural arrangement may allow the first lower cover 210 and the second lower cover 220 to be more securely coupled to the upper cover 100, thereby improving the structural reliability of the entire protective case 10. And when the user holds the protective case 10 with two opposite sides of the first flexible piece 410 and the second flexible piece 420, the first flexible piece 410 and the second flexible piece 420 can also bring better hand feeling to the user.

In addition, traditional upper and lower protective housing that closes the lid structure receives when colliding with in the edge, and the upper and lower lid separates under the effect of external force easily, and then leads to electronic equipment to deviate from in the protective housing. Compared with the conventional protective shell with the upper and lower box covers, when the two opposite sides of the protective shell 10 provided with the first flexible piece 410 and the second flexible piece 420 of the embodiment are impacted by external objects, the first flexible piece 410 and the second flexible piece 420 can play a good role in shock absorption, so that the first lower cover 210 and the second lower cover 220 are prevented from being separated from the upper cover 100 due to impact, the electronic device is prevented from being separated from the protective shell 10, and the electronic device in the protective shell 10 is better protected.

Further, in some embodiments, the first flexible member 410 may extend to the entire outer surface of the first lower cap 210, and the second flexible member 420 may also extend to the entire outer surface of the second lower cap 220. Due to the structural arrangement, on one hand, the connection reliability of the first flexible piece 410 and the second flexible piece 420 and the upper cover 100 can be improved, and on the other hand, the contact area between the hand of the user and the first flexible piece 410 and the second flexible piece 420 can be increased when the user holds the protective shell 10, so that a better holding hand feeling is brought to the user.

In other embodiments, the first lower cover 210 and the second lower cover 220 may be hinged to the upper cover 100.

Referring to fig. 2 and 3, the second lower cover 220 may be formed with a protruding edge 221 protruding from a side close to the first lower cover 210, a second magnet 302 is disposed on a side of the protruding edge 221 away from the upper cover 100, a first magnet 301 corresponding to the second magnet 302 is disposed on a side of the first lower cover 210 close to the upper cover 100, when the first lower cover 210 and the second lower cover 220 are folded, the first lower cover 210 abuts against a side of the protruding edge 221 away from the upper cover 100, and the first magnet 301 and the second magnet 302 are attracted to each other.

As shown in fig. 1 and 2, when a user places an electronic device in the protective case 10 and the second lower cover 220 and the first lower cover 210 are closed, the protruding edge 221 of the second lower cover 220 is located below the first lower cover 210, and the second magnet 302 on the protruding edge 221 of the second lower cover 220 is magnetically connected with the first magnet 301 below the first lower cover 210, such a structure arrangement can both provide a certain support to the first lower cover 210 by using the structure of the protruding edge 221 of the second lower cover 220, and increase the attraction area of the first magnet 301 and the second magnet 302, so that the first lower cover 210 and the second lower cover 220 are more tightly attracted together, thereby improving the connection reliability of the first lower cover 210 and the second lower cover 220, and reducing the risk that the electronic device is separated from the protective case 10 during use. The first magnet 301 and the second magnet 302 are opposite in polarity, or the first magnet 301 and the second magnet 302 are same in polarity as each other.

It should be noted that the first magnet 301 and the second magnet 302 may be magnets, and the term "one side" does not indicate or imply that the magnets must be arranged in a fixed orientation and number. As shown in fig. 2 and 3, in some embodiments, the second magnet 302 may be disposed at intervals on the convex edge 221 of the second lower cover 220 along the length direction L of the second lower cover 220, and correspondingly, the first magnet 301 may be disposed at intervals on the first lower cover 210 near the upper cover 100 along the length direction L of the first lower cover 210. The number of the first magnets 301 and the second magnets 302 is the same, and when the first lower cover 210 and the second lower cover 220 are magnetically connected, each first magnet 301 is magnetically matched with at least one second magnet 302. Since the number of the first and

second magnets

301 and 302 is increased, the first and second

lower covers

210 and 220 are more strongly attracted to each other when they are closed, and the connection is more reliable.

In another embodiment, the second magnet 302 may extend in an elongated shape along the longitudinal direction L of the second lower cover 220 on the protruding edge 221 of the second lower cover 220, and the first magnet 301 may extend in an elongated shape along the longitudinal direction L of the first lower cover 210 on the surface of the first lower cover 210 close to the upper cover 100. The structural arrangement also can make the adsorption force between the first lower cover 210 and the second lower cover 220 larger when the two covers are closed, and the connection is more reliable.

Referring to fig. 2 and 3, in an embodiment, when the first lower cover 210 is folded with the second lower cover 220, the first lower cover 210 is magnetically engaged with the other sides of the upper cover 100 except for the two opposite sides. Wherein, the two opposite sides are two sides of the upper cover 100, the first lower cover 210 and the second lower cover 220, which are respectively connected.

For example, in the embodiment shown in fig. 2, the upper cover 100 is provided with a third magnet 303 at the other side edge than the two opposite sides connected to the first and second

lower covers

210 and 220, and the first lower cover 210 is also provided with a fourth magnet 304 at the corresponding one side edge. When the first lower cover 210 and the second lower cover 220 are closed, the side of the first lower cover 210 provided with the third magnet 303 is attached to the side of the upper cover 100 provided with the fourth magnet 304, the third magnet 303 and the fourth magnet 304 are attracted and matched, and the upper cover 100 is attracted and matched with the first lower cover 210 through the third magnet 303 and the fourth magnet 304. The end of the third magnet 303 close to the fourth magnet 304 and the end of the fourth magnet 304 close to the third magnet 303 are opposite poles, or the third magnet 303 and the fourth magnet 304 are same poles as each other. Similarly, the upper cover 100 is further provided with a fifth magnet at the opposite side where the third magnet 303 is provided, and the first lower cover 210 is also provided with a sixth magnet at the corresponding one side edge. The arrangement and the matching manner of the fifth magnet and the sixth magnet can refer to the arrangement and the matching manner of the third magnet 303 and the fourth magnet 304, and the description is omitted here.

Therefore, when the first lower cover 210 and the second lower cover 220 are folded, the first lower cover 210 can be magnetically engaged with the other two opposite sides of the upper cover 100. Due to the structural arrangement, on the basis that the first lower cover 210 and the second lower cover 220 are magnetically attracted, the other two opposite sides of the first lower cover 210 and the other two opposite sides of the upper cover 100 are directly attracted, and the connection reliability of the first lower cover 210 and the upper cover 100 is improved. When the first lower cover 210 and the second lower cover 220 are folded and the first lower cover 210 abuts against the convex edge 221 of the second lower cover 220, the convex edge 221 of the second lower cover 220 is also reliably attached to the upper cover 100 under the limitation of the structure of the first lower cover 210 due to the absorption force between the first lower cover 210 and the upper cover 100, thereby further reducing the risk of the electronic device being detached from the protective case.

In some embodiments, the second lower cover 220 may also be magnetically engaged with other sides of the upper cover 100 than the two opposite sides. The arrangement and the matching manner of the second lower cover 220 and the upper cover 100 can refer to the arrangement and the matching manner of the first lower cover 210 and the upper cover 100, and the description is omitted here.

In some embodiments, the number of the third and

fourth magnets

303, 304 may be multiple, a plurality of the third magnets 303 are spaced apart from one side edge of the upper cover 100, and a plurality of the fourth magnets 304 are spaced apart from the corresponding side edge of the first lower cover 210 corresponding to the third magnets 303. When the first lower cover 210 and the upper cover 100 are magnetically coupled, each of the third magnets 303 is in attractive engagement with at least one of the fourth magnets 304. Since the number of the third and

fourth magnets

303 and 304 is increased, the first lower cover 210 and the upper cover 100 are more strongly attracted when they are closed, and the connection is more reliable.

Referring to fig. 1 and 2, the first lower cover 210 may be formed with a handle portion 211 at a side close to the second lower cover 220, and the handle portion 211 is configured to drive the first lower cover 210 to rotate in a direction away from the second lower cover 220 relative to the upper cover 100 under an external force until the first lower cover 210 is separated from the second lower cover 220.

Specifically, in the embodiment shown in fig. 2, the handle portion 211 is formed by notching the first lower cover 210 at a side edge close to the second lower cover 220. Therefore, when the first lower cover 210 and the second lower cover 220 are closed, the user can put his hand into the slot to operate the first lower cover 210 to rotate relative to the upper cover 100 in a direction away from the second lower cover 220, so that the first lower cover 210 and the second lower cover 220 are separated to take out the electronic device. Therefore, the provision of the clasping portion 211 makes it easier for the user to open the protective case 10, improving the convenience of the user's operation.

In some embodiments, a through hole 230 corresponding to a lens of the electronic device may be formed on either one of the first lower cover 210 and the second lower cover 220.

For example, in the embodiment shown in fig. 1, the first lower cover 210 is provided with a through hole 230, and when the first lower cover 210 and the second lower cover 220 are closed, the through hole 230 can provide a passage for a lens of the electronic device, so that the lens can maintain normal shooting without being blocked.

Further, in some embodiments, the protective case 10 may further include a cover plate 240 covering the through hole 230, wherein the cover plate 240 is used for shielding a lens of the electronic device. The cover 240 may be rotatably or slidably connected to the first lower cover 210, so that the through hole 230 can be opened or closed by the movable cover 240.

Further, in some embodiments, the cover plate 240 may be detachably connected to the first lower cover 210 by clipping, hanging, or the like. Such a structure allows a user to select whether to install the cover 240 on the first lower cover 210 or to replace the cover 240 when the cover is damaged according to his or her needs.

Further, in some embodiments, the cover plate 240 may also be a transparent cover plate, such as an acrylic cover plate, a glass cover plate, and the like.

In addition, in an embodiment, still relate to an electronic device, this electronic device includes electronic equipment and the protective housing in any preceding embodiment.

The electronic device can be installed in cooperation with the protective shell 10, and the protective shell 10 can wrap the electronic device integrally to form the electronic device. During the installation process, a user may hold the two opposite sides of the upper cover 100, on which the first lower cover 210 and the second lower cover 220 are disposed, with hands, place the electronic device on the upper cover 100 between the first lower cover 210 and the second lower cover 220, and then connect the first lower cover 210 and the second lower cover 220 to wrap the electronic device. When the protective case 10 is used for enclosing and wrapping the electronic device, the hands of the user are not located at the closed position, that is, at the joint of the first lower cover 210 and the second lower cover 220, so that the hands of the user can be prevented from being clamped in the box cover process, and better use experience is brought to the user. Because the first lower cover 210 and the second lower cover 220 are detachable, a user can select whether to add the protective case 10 on the electronic device according to actual needs of the user, and the protective case 10 can be replaced in time when the protective case 10 is aged, so that the electronic device inside the protective case 10 can be better protected.
