The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0022] The reference to "embodiment" in the present invention means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art of the present invention that the embodiments described in the present invention may be combined with other embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 4 As shown, the utility model of the rear shell of the smart terminal with a support frame with adjustable angle includes a shell 1, a support frame 4 hinged to the back of the shell 1 through a pin shaft 11, a first limiting structure 5 is provided on the support frame 4, and a second limiting structure 6 is provided at the bottom of the shell 1, the first limiting structure 5 and the second limiting structure 6 are in frictional contact with the placement surface, and the distance between the first limiting structure 5 and the second limiting structure 6 can be adjusted by the pin shaft 11, thereby adjusting the placement angle of the smart terminal shell on the placement surface.

[0025] As an embodiment of the utility model, the smart terminal of this example is a tablet computer. The support frame 4 of this example is U-shaped, including two support arms, a connecting rod 8 is arranged between the two support arms, and the first limiting structure 5 is arranged on the connecting rod 8. The support frame also includes a free end arranged at the end of the two support arms, and the free end is provided with a hinge hole. Corresponding to the two free ends, two bases 3 are arranged on the back of the shell 1 in this example, and the base is provided with a groove matching the free end, and the side walls on both sides of the groove are provided with mounting holes corresponding to the hinge holes, and the pin shaft 11 can pass through the mounting hole and the hinge hole to realize the hinge connection between the support frame and the base. The base 3 of this example is mainly made of aluminum alloy, which is light and has good thermal conductivity and heat dissipation effects.

[0026] In this example, a design in which one pin shaft 11 passes through two side wall mounting holes can be adopted, or two pin shafts 11 can be respectively connected to the two side wall mounting holes and the free ends.

[0027] The groove in this example is provided at one end of the base 3, and a threaded hole for fixing the base 3 on the housing 1 is provided at the other end of the base 3, and the base 3 is fixed to the housing 1 by screws. In order to prevent dust and water, a silicone protective pad 2 is provided in the threaded hole to fill the threaded hole and slightly protrude from the threaded hole.

[0028] Since the support frame 4 of this example is hinged to the base, the angle can be adjusted at will. Therefore, in order to store and limit the support rod 4 when not in use, two fixed holders 7 for storing the support frame 4 are also provided on the shell 1. The fixed holders 7 are provided at the back of the shell and at positions corresponding to both sides of the folded connecting rod 8, and can also be provided at positions corresponding to the support arms. Preferably, the position of the fixed holders 7 does not interfere with the first limiting structure. The number of fixed holders 7 of this example is not limited to two, and can also be set to other numbers.

[0029] Preferably, the first limiting structure 5 of this example is one or more silicone strips that wrap the entire connecting rod 8 or one end of it. When the tablet of this example is not in use, the support frame 4 can be stored by fixing the base 7. When the back of the shell is placed on the placement surface, the silicone protective pad 2 and the silicone strip on the back of the shell 1 directly contact the placement surface, thereby protecting the shell 1 and avoiding wear on other parts of the shell.

[0030] like Figure 1 and Figure 2 As shown, the second limiting structure 6 of the utility model is a silicone structure or a rubber structure arranged at the lower end of the housing 1. The second limiting structure 6 of this example is a silicone protective structure arranged to wrap the two corners 101 at the lower end of the housing, and the first limiting structure 5 is arranged between the two silicone protective structures of the second limiting structure 6, and the positions of the first limiting structure 5 and the second limiting structure 6 are distributed in a triangular shape.

[0031] The silicone protective structure of this example is fixed to the corner 101 through a plurality of screw holes 1011 arranged along the corner 101. The triangular distribution makes the friction surface distribution of the utility model more stable, so as to provide stable support for the tablet computer with adjusted angle.

[0032] Of course, the second limiting structure 6 of this example can also be arranged on the bottom edge 102 between the two corners 101 .

[0033] like Figure 1-Figure 4As shown, the rear shell of the smart terminal can be used as the bottom shell of the smart terminal, fixedly connected to the middle frame or the front shell of the smart terminal. Alternatively, the rear shell of the smart terminal in this example can also be set to be detachable from the smart terminal and used to protect the protective shell of the smart terminal.

[0034] The rear shell of the smart terminal described in this example is a part of the tablet computer. When used as a bottom shell, the lower half of the shell 1 in this example is a battery slot 103 for installing a battery. In order to improve the heat dissipation performance of the tablet computer, in this example, a plurality of parallel heat dissipation strips 9 are arranged on the upper half of the back side of the shell 1, and heat dissipation channels 10 are arranged between adjacent heat dissipation strips 9. The base 3 is arranged on the top of the heat dissipation strips 9, and more than one heat dissipation channel 10 arranged in parallel is arranged under the base.

[0035] The base 3 is provided with a protruding heat dissipation strip 9. On the one hand, the structure of the shell 1 can be improved through the silicone protective pad 2 and the silicone strip. On the other hand, in addition to the heat dissipation channel 10, the base 3 can serve as a supporting foot to form a second heat dissipation surface between the base 3 and the shell 1, so that air can circulate and accelerate the heat dissipation effect.

[0036] like Figure 3 and Figure 4 As shown, the long silicone strip and the pin 11 in this example are the core of the support frame's angle adjustment. The support frame 4 is fixed to the shell 1 by screws, and the pin 11 runs through the support frame 4 and the base 3 to combine the two together. The support frame 4 can be rotated by the pin 11. At the same time, the friction with the plane is increased through the more elastic silicone to achieve the support frame's angle adjustment, which is convenient for users to operate the tablet interface from multiple angles.

[0037] The utility model respectively arranges a first limiting structure and a second limiting structure at the bottom of the support frame and the shell body to increase the friction between the bracket and the plane when the bracket is placed on the plane, so as to achieve the purpose of stepless angle adjustment; compared with the existing smart terminals without angle adjustment function, or the existing protective shell structures are complicated, many of which can only be placed at a single angle, the utility model greatly facilitates user use.

[0038] The support frame of the utility model is fixed by screws to ensure reliability; by arranging the second limiting structure at the corners of the shell, the corners are protected and a triangular distribution can be formed, so that the position of the smart terminal of the utility model is adjusted and placed, which makes it more stable.

[0039] In addition, the utility model also designs a holder for fixing the bracket of the tablet computer when not in use. The support frame can be laid flat and fixed on the holder. When laid flat, in order to prevent the support frame from direct collision and impact with the desktop, a protective silicone pad is designed on the base to play a buffering role, which greatly improves the user experience, convenience and reliability.

[0040] The specific implementation methods described above are preferred implementation methods of the present utility model, and are not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation methods of the present utility model. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
