[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a shockproof and stable circuit board for a smart watch of the utility model comprises a smart watch case 1 and a circuit board 2, a plurality of positioning posts 7 are installed on the inner wall surface of the smart watch case 1, a plurality of positioning holes are provided on the circuit board 2, the circuit board 2 is placed inside the smart watch case 1, the positioning posts 7 are inserted into the corresponding positioning holes, a fixing ring 3 is installed outside the circuit board 2, a plurality of pressure-bearing parts 4 are protruded from the fixing ring 3, and a taking-in and putting-out opening are formed between adjacent pressure-bearing parts 4, a plurality of positioning grooves 10 are provided on the open end surface of the smart watch case 1, and a fixing frame 5 for pressing the pressure-bearing part 4 and the circuit board 2 is provided in the positioning grooves 10.

[0023] In this embodiment, the positioning groove 10 is arranged to avoid the button port or operation port on the smart watch housing 1, and the fixing frame 5 is arranged in a "U"-shaped structure, one end of the fixing frame 5 extends to the inside of the smart watch housing 1 and is bent outward to form an extrusion portion 6, and the extrusion portion 6 is arranged to contact the top surface of the pressure-bearing portion 4, and the outer sleeve of the smart watch housing 1 is provided with a locking ring 9, and the locking ring 9 is movably connected to the end of the fixing frame 5 located on the outside;

[0024] Among them, since buttons or rotary knobs will eventually be installed on the outer ring of the smart watch, the locking ring is arranged under the smart watch casing. After the locking ring moves upward, it will eventually contact the buttons. Therefore, the locking ring cannot be removed from the smart watch casing, avoiding loss. However, the moving distance can move the extruding part away from the pressed part and allow the circuit board to have an upward moving space, so that the circuit board can be smoothly detached from the positioning column.

[0025] In this embodiment, an internal thread is provided on the inner ring surface of the locking ring 9, and an external thread is provided on the outer ring surface of the smart watch housing 1. The locking ring 9 is meshed and connected with the external thread on the smart watch housing 1 through the internal thread. The end surface of the fixing frame 5 located on the outside is provided with a connecting groove with an arc shape in the plane. A connecting ring 8 is installed on the top surface of the locking ring 9, and the connecting ring 8 is movably connected to the connecting groove.

[0026] In this embodiment, the vertical cross-sections of the connecting ring 8 and the connecting groove are both arranged in a trapezoidal structure, so that the connecting ring can only rotate in a circle in the connecting groove, thereby preventing separation.

[0027] In this embodiment, the width of the positioning groove 10 matches the width of the fixing frame 5, and the top surface of the fixing frame 5 is flush with the opening end surface of the smart watch case 1. After the fixing frame moves down to the specified position, the top surface of the fixing frame is flush with the opening end surface of the smart watch case, thereby avoiding affecting subsequent installation.

[0028] In this embodiment, the inner side surface of the fixing frame 5 is respectively set to contact the outer ring surface and the inner ring surface of the smart watch housing 1, so that the fixing frame can only move up and down along the inner ring and outer ring of the smart watch housing, thereby increasing stability.

[0029] In this embodiment, the fixing ring 3 and the pressure-bearing portion 4 are integrally stamped and formed, and the fixing ring 3 and the fixing frame 5 are made of metal material, which increases firmness and service life, and the integral stamping method has lower cost.

[0030] During installation, the circuit board is directly placed into the housing of the smart watch. During the placement process, the access port is first aligned with the fixing frame. After the circuit board is moved to the bottom of the fixing frame, the circuit board is rotated so that the pressure-bearing portion on the fixing ring is aligned with the fixing frame, and the positioning hole is aligned with the positioning column. As the circuit board continues to move downward, the positioning column can be inserted into the positioning hole to complete the positioning of the circuit board.

[0031] After the above is completed, the locking ring is directly rotated to move the locking ring downward along the thread. The movement of the locking ring drives the connecting ring, and the connecting ring is movably connected to the fixing frame. Therefore, the connecting ring only applies a downward pulling force to the fixing frame, so that the fixing frame moves downward along the positioning groove until the extruding part presses the pressed part downward and fixes it, and the circuit board is also locked and fixed;

[0032] When disassembling, the locking ring is rotated in the opposite direction to move upward along the thread and lift the fixing frame upward. After the extrusion part of the fixing frame is removed from the pressure part, the circuit board can move upward. After the positioning plate is separated from the positioning column, it can rotate in a circle to move the pressure part away from the bottom of the fixing frame until the access opening is opposite to the fixing frame. The circuit board can be directly taken out upward through the access opening, which greatly facilitates disassembly.

[0033] Through the above, no screws or other workpieces are needed for installation and disassembly, which greatly increases the convenience. In addition, the locking stability can be ensured by pressing down the fixing frame synchronously, thereby avoiding loosening and achieving a shockproof effect.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
