In the embodiment shown in fig. 2, the transparent cover 200 is rotatably connected to the main housing 100 at the first side 200A. The second side 200B and the fourth side 200D of the transparent cover 200 may be respectively provided with a rotating shaft 220 at a position close to the first side 200A, and a hole portion rotatably engaged with the rotating shaft 220 is provided in the receiving cavity 112 of the main housing 100; alternatively, the rotating shaft 220 may be disposed in the receiving cavity 112 of the main housing 100, and hole portions rotatably engaged with the rotating shaft 220 may be disposed at positions of the second side portion 200B and the fourth side portion 200D of the transparent cover 200, which are close to the first side portion 200A. In one embodiment, the shaft 220 may be a cylindrical shaft and the bore portion may be a cylindrical bore. In the embodiment shown in fig. 4, the rotating shaft 220 may be a cylindrical shaft, and the sliding slot 112A may be a long strip.

In one embodiment, since the transparent cover 200 can serve as a support for supporting the main housing 100 when the receiving cavity 112 is opened, in order to further improve the flexibility of the protective shell, the protective shell supports the main housing 100 at various angles, and a damped fit is adopted between the transparent cover 200 and the main housing 100. As shown in fig. 2, in the embodiment, the rotation shaft 220 and the hole portion are rotatably engaged with each other between the transparent cover 200 and the main housing 100, the rotation shaft 220 (see fig. 6) may be the rotation shaft 220 having a certain elasticity in the radial direction, for example, the rotation shaft 220 may be made of an elastic material such as rubber, and the radial dimension of the rotation shaft 220 is slightly larger than the diameter of the hole portion, so that when the rotation shaft 220 is engaged with the hole portion, the inner wall of the hole portion is tightly engaged with the outer wall of the rotation shaft 220, and the inner wall of the hole portion compresses the outer wall of the rotation shaft 220 to some extent, thereby increasing the friction between.

In some embodiments, anti-slip members, such as anti-slip rubber, may be disposed on the outer protrusion 210, as shown in fig. 2, and serve as a support for supporting the main housing 100 when the transparent cover 200 is opened from the receiving cavity 112, and the anti-slip members can increase the friction between the main housing 100 and the supporting surface, thereby preventing slipping.

Electronic equipment can generate heat when using usually, and when traditional protective housing cover was on electronic equipment, the protective housing lived electronic equipment's tight parcel, leads to the heat that electronic equipment produced to be difficult to in time effluvium. Particularly, in the charging process of the electronic equipment, the electronic equipment can generate a large amount of heat, the temperature of the battery is increased along with the accumulation of the heat, the aging of the battery is accelerated, and potential safety hazards are easily caused by high temperature.

In one embodiment, as shown in fig. 4, the accommodating cavity 112 and the mounting cavity 111 are communicated, that is, when the electronic device is mounted in the mounting cavity 111, the back shell of the electronic device can be in direct contact with the space of the accommodating cavity 112. As shown in fig. 5A and 5B, when the transparent cover 200 opens the accommodating cavity 112, the accommodating cavity 112 is communicated with the external space, and the back shell of the electronic device is in direct contact with the space of the accommodating cavity 112, so that the back shell of the electronic device can be in contact with the external space. Thereby accelerating heat dissipation of the electronic device. Especially, when the electronic device is charged, the transparent cover plate 200 can be opened, so that the heat dissipation of the electronic device is accelerated, the whole protective shell does not need to be detached from the electronic device, and the portability of the protective shell is improved.

As shown in fig. 6, fig. 6 is an exploded view of a protective casing according to an embodiment of the present invention, the protective casing includes a main casing 100 and a transparent cover 200 disposed on a back surface 102 of the main casing 100, a front surface 101 of the main casing 100 is provided with a mounting cavity 111 (as shown in fig. 4), and an electronic device is configured to be mounted in the mounting cavity 111. Further, the main housing 100 includes a main body 110, a side frame 120, and a metal frame 130, wherein the side frame 120 is fixedly connected to the main body 110, and the metal frame 130 is fixedly connected to the side frame 120. The main body 110 is provided with a mounting cavity 111 for mounting electronic equipment, the transparent cover plate 200 is arranged on the main body 110, and the transparent cover plate 200 and the main body 110 enclose an accommodating cavity 112 for accommodating articles.

The main body 110 may be made of a hard material, such as PC or other hard plastic. The side frame 120 may be formed on the main body 110 by a two-shot molding process, and the side frame 120 may be made of a flexible material, such as TPU material or other soft rubber material, so that the side frame 120 has excellent cushioning and shock absorbing properties. Side frame 120 still is provided with slot part 121 in the one side that deviates from main part 110, and metal frame 130 is installed in slot part 121, and metal frame 130 has better rigidity, can regard as the reinforcement of protective housing, makes the protective housing be difficult to warp. The side frame 120 and the metal frame 130 may be formed as a complete ring structure, so as to provide better protection for the main body 110.

The metal frame 130 is not in direct contact with the main body 110, and the metal frame 130 is connected to the main body 110 through the side frame 120. The electronic device is directly mounted on the body part 110. When the protective case drops, if the metal frame 130 lands first, the metal frame 130 has a high rigidity, and can prevent the protective case from deforming. However, since the metal frame 130 has high rigidity, that is, the metal frame 130 has high hardness, and the metal frame 130 has high vibration-conducting capability, the metal frame 130 in this embodiment is not directly connected to the main body 110, but indirectly connected to the main body 110 through the more flexible side frame 120. Thus, even if the metal bezel 130 generates a large impact force after being clamped to the ground, the impact force is transmitted to the side frame 120, and the side frame 120 absorbs the impact force through its own flexible material, thereby attenuating the impact force transmitted to the main housing 100. Therefore, the electronic product on the main body 110 is finally subjected to a smaller impact force, and the integrity of the electronic product is ensured.

In the embodiment shown in fig. 6, the transparent cover 200 is provided with the external protrusion 210, and as shown in fig. 1, when the transparent cover 200 is covered on the main casing 100, the external protrusion 210 protrudes from the main casing 100, so that a user can open the transparent cover 200 conveniently through the external protrusion 210. Referring to fig. 1 and 6, when the transparent cover 200 is covered on the main housing 100, the outer protrusion 210 abuts against the metal frame 130. The metal frame 130 may be made of a material that can be attracted by a magnetic material, and the outer protrusion 210 may be provided with a magnet, so that the transparent cover plate 200 can be firmly covered on the main housing 100 by the magnet and the metal frame 130 being attracted to each other. Specifically, as shown in fig. 6, a groove 131 is provided on the metal frame 130, and when the transparent cover 200 is covered on the main housing 100, the outer protrusion 210 of the transparent cover is received in the groove 131.
