Description

Electronics with multi-angle positioning bracket

technical field

The utility model relates to an electronic device, in particular to an electronic device with a bracket.

Background technique

A portable electronic device, such as an electronic photo frame, usually has a stand for supporting the electronic device when it is placed on a table. A problem existing in the existing bracket is: the bracket cannot rotate relative to the electronic device, but can only be fixed at one supporting position, or although it can rotate relative to the electronic device, it can only be positioned at two extreme positions. In this way, when the electronic device is placed on the table, there can only be one or two fixed angles. This obviously cannot meet the diverse needs of users.

Utility model content

The utility model provides an electronic device with a bracket, and the bracket can be positioned at multiple angles.

The electronic device includes a back cover and a bracket, the bracket and the back cover respectively include a first contact surface and a second contact surface in contact with each other, the bracket is rotatably mounted on the back cover, and at least one The spring ball protruding from the second contact surface is formed on the support with several positioning holes matching with the spring ball, and the several positioning holes are distributed on a circle centered on the pivot axis.

Due to the cooperation of the spring ball and the positioning hole, the bracket can be positioned at multiple angles.

Detailed ways

Please refer to FIG. 1 and FIG. 2 , which disclose an electronic device 10 according to a preferred embodiment of the present invention. The electronic device 10 includes a rear cover 20 and a bracket 30 . The bracket 30 is rotatably mounted on the rear cover 20 . In this embodiment, the bracket 30 is installed on the rear cover 20 through screws 40 .

Please refer to FIG. 3 and FIG. 4 , which disclose the connection structure of the rear cover 20 and the bracket 30 . The bracket 30 is roughly spoon-shaped, and one end thereof includes a first contact surface 32 , and a through hole 33 is formed from the first contact surface 32 . Surrounding the hole 33, a number of positioning holes 34 and two position-limiting protrusions 35 are respectively formed on the first contact surface 32. The positioning holes 34 are hemispherical blind holes located on a circle centered on the center of the hole 33. The position protrusions 35 are symmetrically distributed around the hole 33 .

The back cover 20 includes a second contact surface 22 corresponding to the first contact surface 32 on the bracket 30 , and a through hole 23 is formed on the second contact surface 22 . Surrounding the hole 23 , two through holes 24 corresponding to the positioning holes 34 and two arc-shaped limiting grooves 25 corresponding to the limiting protrusions 35 are respectively formed on the second contact surface 22 . Two hooks 26 are formed on the other surface of the back cover 20 opposite to the second contact surface 22 (refer to FIG. 5 ).

The electronic device 10 also includes spring balls 70 having the same number as the through holes 24 on the second contact surface 22 , a nut 60 , and a cover plate 50 . Each spring ball 70 includes a spring 71 and a cylinder 72 , the top of the cylinder 72 is hemispherical, and a ring flange 73 is formed in the middle. The cover plate 50 is formed with two locking holes 52 corresponding to the hooks 26 and two receiving holes 51 for receiving the spring balls 70 .

Please refer to Fig. 3, Fig. 4 and Fig. 5. When installing, first place the nut 60 between the two hooks 26, place the spring ball 70 in the through hole 24 on the back cover 20, and then let the cover plate 50 pass through. The engaging hook 26 and the engaging hole 52 are fixed on the rear cover 20 . At this time, the cover plate 50 and the hook 26 work together to fix the nut 60 on the rear cover 20; the spring 71 of the spring ball 70 is located in the receiving hole 51 on the cover plate 50, and the top of the cylinder 72 passes through the through hole 24 protruding from the second contact surface 22 . Due to the limitation of the flange 73 , the spring ball 70 cannot fall out of the through hole 24 .

When the user intends to use the electronic device 10, the screw 40 is passed through the holes 33, 23 to cooperate with the nut 60, the hemispherical positioning hole 34 on the bracket 30 is matched with the hemispherical top of the cylinder 72, and the hemispherical top of the bracket 30 The limiting protrusion 35 is located in the limiting groove 25 , so that the bracket 30 and the rear cover 20 are rotatably connected together.

Please refer to FIG. 1 at the same time, the bracket 30 can rotate between two extreme angles on the axis of the screw 40 . When the bracket 30 does not rotate, due to the cooperation of the spring ball 70 and the positioning hole 34 , the bracket 30 can be positioned at a specific angle, and the specific angle is one of multiple angles determined by the distribution of the positioning holes 34 . When the rotating force received by the bracket 30 is greater than the elastic force between the spring ball 70 and the positioning hole 34 , the bracket 30 rotates. When the bracket 30 rotates, the spring ball 70 continuously withdraws from the last positioning hole 34, and then enters the next positioning hole 34 after rotating for a certain distance, thereby making a "clicking" sound. When the bracket 30 rotates, the position-limiting protrusion 35 moves in the position-limiting slot 25 accordingly. When the bracket 30 rotates to a limit angle, the position-limiting protrusion 35 moves to the edge of the position-limiting slot 25, thereby preventing the bracket 30 from further rotation.

The structure of the utility model is not limited to those disclosed in the above embodiments. For example: the number of the spring ball 70 or the limit protrusion 35 can also be one, three or more. The spring ball 70 can also be fixed to the rear cover 20 by welding or other known methods.
