DETAILED DESCRIPTION

[0039] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, therefore only as an example, and cannot limit the protection scope of the utility model.

[0040] Please refer to Figure 1 , Figure 1 A perspective view of an embodiment of the electronic device support protective shell of the utility model is shown, wherein the electronic device support protective shell is used for protecting an electronic device and providing support for the electronic device. The electronic device can be a tablet computer, a learning machine, a large-size mobile phone, etc., and the embodiment of the utility model does not make specific limitation. The electronic device support protective shell comprises a protective shell body 100 and a support 200 connected to the protective shell body 100. Wherein, the transverse width of one end of the support 200 connected to the protective shell body 100 is less than the transverse width of the other end of the support 200 to form a stable support structure of the support 200 and the protective shell body 100.

[0041] The transverse width of the support 200 gradually increases, which can be various shapes with gradually increasing transverse width, and the utility model does not make specific limitation. In an embodiment of the utility model, the transverse width of the support 200 gradually increases from one end connected to the protective shell body 100 to the other end of the support 200, so that the support 200 is close to or triangular structure, so that the stability of the support 200 increases. In order to realize the stability of the support, the transverse width of the support 200 increases obviously along the direction of the desktop support, so that the width of the part of the support 200 contacting the desktop increases when supporting, so that the contact area increases, which can adapt to the characteristics of large size and heavy weight of the tablet computer, so that the support is stable.

[0042] Specifically, in one embodiment of the utility model, the support 200 includes a longitudinally arranged connecting portion 210 and a supporting portion 220. The connecting portion 210 and the supporting portion 220 can be designed as an integral molding. One end of the connecting portion 210 is connected to the protective shell body 100, and the other end is connected to the first end of the supporting portion 220. The lateral width of the supporting portion 220 gradually increases from the first end to the second end. The second end is the end of the supporting portion 220 that is away from the first end and is used to contact the supporting surface. The connecting portion 210 can be a square structure or other shapes, for example, it can be a square structure with the same lateral width as the first end of the supporting portion 220. One side of the square structure is connected to the protective shell body 100, and the other side opposite to the one side is connected to the first end of the supporting portion 220. The overall shape of the supporting portion 220 can be a triangle, one of the bottom sides of the triangle is used for support, and the vertex opposite to the bottom side is used for connecting to the connecting portion 210. It can be understood that in the embodiment of the utility model, the overall shape of the supporting portion 220 is a triangle, and the vertex opposite to the bottom side has a certain lateral width, which can be consistent with the lateral width of the square connecting portion 210, and the utility model does not make specific limitations. Because the lateral width of the supporting portion 220 increases, the size of the supporting portion 220 increases, which makes the weight of the support 200 increase, therefore, in order to ensure the lightness of the structure of the support 200, the supporting portion 220 in the embodiment of the utility model includes at least one hollow structure, which can include a large hollow structure, or a net-shaped hollow structure, a honeycomb hollow structure, etc., and the embodiment of the utility model does not make limitations, thereby reducing the weight of the support 200. For example, in one specific implementation, the supporting portion 220 is a triangular structure, and the middle of the triangular structure is hollow, which makes the supporting portion 220 become a triangular frame. Through such a design, on the one hand, the lightness of the support 200 is improved; on the other hand, through the design of the hollow middle, the user can easily pull the support 200 from the storage state to the unfolded state, which enhances the user experience. The connecting portion 210 can be directly connected to the protective shell body 100, which can be fixedly connected at a preset angle, or can be rotatably connected to the protective shell body 100 through a shaft hole, a shaft and a support shaft hole 520 provided on the connecting portion 210.

In an embodiment of the present application, the inner surface of the protective shell body 100 is provided with a rotating piece containing groove around the opening structure 500, so that the lower rotating piece 420 can be contained in the rotating containing groove, thereby making the inner surface of the protective shell body 100 flat. The outer surface of the protective shell body 100 is also provided with a rotating piece containing groove around the opening structure 500, so that the upper rotating piece 410 can be contained in the rotating piece containing groove. In a specific implementation, the limiting structure can be a first protruding part arranged on the upper rotating piece 410 or the lower rotating piece 420. Specifically, the limiting structure is at least one first protruding part arranged on the surface of the upper rotating piece or the lower rotating piece in contact with the protective shell body, and the first protruding part is matched with the limiting groove.

[0045] In another specific implementation, as Figures 3-6As shown, the limiting structure 540 can also be clamped between the upper rotating member 410 and the lower rotating member 420. One end of the limiting structure 540 is fixedly connected with the upper rotating member 410 and / or the lower rotating member 420, and the other end forms a cantilever structure. A second protruding portion is arranged on the surface of the cantilever structure that is in contact with the protective shell body. The second protruding portion cooperates with the limiting groove, and is clamped in at least one limiting groove 1101 on the protective shell body 100. The second protruding portion is arranged on the surface of the cantilever structure that is in contact with the protective shell body. The surface can be opposite to the groove bottom 110, or can be the surface in contact with the groove side 120. Correspondingly, the limiting groove 1101 can be arranged on the groove bottom 110 or the groove side 120 of the rotating member receiving groove of the protective shell body 100, that is, the part of the protective shell body that is clamped by the upper rotating member 410 and the lower rotating member 420.

[0046] In a specific implementation, as shown in Figure 7 and Figure 8 The limiting structure 540 can include an elastic member and a second protruding portion. One end of the elastic member is fixed on the rotating structure, and the other end is connected with the second protruding portion. The second protruding portion abuts against the limiting groove 1101. One end of the elastic member can be fixed with the upper rotating member 410 and / or the lower rotating member 420, and the second protruding portion abuts against the groove side 120 of the rotating receiving groove of the protective shell body 100. The elastic member can be a first spring 5401A, and the second protruding portion can be an abutting member 5402A that is sleeved and fixed on one end of the first spring. One end of the first spring 5401A is fixed with the upper rotating member 410 and / or the lower rotating member 420, and the other end is fixed with the abutting member 5402A. The abutting member 5402A is used to abut against the limiting groove 1101, which can be arranged on the groove side 120 of the rotating receiving groove. The spring and the abutting member are arranged in the limiting structure accommodating groove, so that the first spring 5401A and the abutting member 5402A move along the direction of spring expansion and contraction. Figure 9 and Figure 11In another specific implementation, as shown, the elastic member can be a second spring 5401B, and the second protruding portion can be a spherical ball 5402B in abutment with the other end of the second spring 5401B. The one end of the second spring 5401B is fixed with the rotating structure, and the other end of the second spring 5401B is in abutment with the one end of the spherical ball 5402B. The second spring 5401B and the spherical ball 5402B are externally sleeved with a cylindrical structure 550B, and the other end of the spherical ball 5402B partially protrudes from the cylindrical structure 550B and is in abutment with the limiting groove 1101. The limiting groove can be arranged on the groove edge 120 of the rotating receiving groove of the protective shell body 100.

[0047] In the embodiment of the utility model, the connecting part 210 is rotatably connected with the rotating structure through the rotating shaft 510, so that the support 200 is in a storage state or an unfolded state. Specifically, the upper rotating part 410 is provided with a rotating shaft placing opening for accommodating the rotating shaft 510. The two ends of the rotating shaft placing opening are provided with two fixing holes. One end of the connecting part 210 is provided with a shaft hole.

The upper rotating part 410 includes an upper end part and a lower end part. The outer surface of the upper end part is higher than that of the lower end part. The rotating shaft placing opening is arranged between the upper end part and the lower end part. When the connecting part 210 rotates relative to the rotating part through the rotating shaft 510, the upper end part is abutted when rotated to a preset angle, so that the support 200 is in a completely unfolded state at the preset angle and forms the support 200 structure with the protective shell body 100. The rotating shaft 510 is further provided with a reinforcing fixing part 530. The two ends of the rotating shaft 510 are connected with the rotating structure.
