Description

Technical Field

[0001] The present invention relates to the field of protective shell design, and more particularly to a wristband bracket structure for a mobile phone case. Background Art

[0002] A mobile phone, also known as a mobile telephone or wireless telephone, is commonly called a mobile phone. It was originally just a communication tool and was commonly known as a "big brother phone" in the early days. It is a portable telephone terminal that can be used within a relatively wide range. With the continuous improvement of technology, the price of mobile phones has gradually increased, so the demand for mobile phone cases has greatly increased. A mobile phone case refers to the outer shell of a mobile phone. The commonly used plastic materials for mobile phone cases mainly include three categories: PC, ABS, and PC + ABS.

[0003] In the prior art (Publication No.: CN216217037U, Publication Date: April 5, 2022), a new type of mobile phone case is disclosed. The new mobile phone case is provided with a fixed frame, and a fixed bracket is arranged inside the fixed frame. The flip bracket forms a flip structure inside the fixed bracket through a rotating shaft, so that the flip bracket can provide a mobile phone bracket for mobile phone users, facilitating their use.

[0004] In the prior art (Publication No.: CN222073221U, Publication Date: November 26, 2024), a mobile phone case with a sliding bracket is disclosed. The bracket at one end of the mobile phone case body is hinged and rotated to drive the other end to slide on the chute, causing the bracket to contract and arch, so that the bracket has a supporting function.

[0005] In the prior art (Publication No.: CN221828944U, Publication Date: October 11, 2024), a bracket-integrated wristband mobile phone case is disclosed. An elastic band and a folded wristband are installed on the back of the leather case. When using the mobile phone normally, fingers or palms can pass between the folded wristband and the elastic band, effectively preventing the mobile phone from falling even if it is not held firmly.

[0006] In the above various mobile phone case solutions and the mobile phone case solutions of the prior art, in order to facilitate the use of mobile phones and other electronic devices, types such as wristband mobile phone cases, bracket mobile phone cases, and magnetic mobile phone cases are provided. However, when used for large-screen mobile phones (such as foldable mobile phones) or tablets, the support of the back bracket of the mobile phone case is often unstable. In addition, most mobile phone cases on the market have only one function. For example, a wristband mobile phone case does not have the function of a bracket, while a bracket mobile phone case does not have the function of a wristband, and it will also block the wireless charging area, resulting in great inconvenience for users. In addition, if the wristband, bracket and other technologies in the prior art are simply applied to the mobile phone case, the mobile phone case will become too heavy, seriously affecting the portability of the mobile phone. Therefore, it is necessary to provide a wristband bracket structure for the mobile phone to solve these technical problems. Summary of the Invention

The sliding limiting member 2 is slidably installed on the rotation limiting member 1, and a wristband bracket 4 is rotatably installed on one side of the sliding limiting member 2 in a damped manner, and the soft wristband 3 is installed in the wristband bracket 4; The principle is as follows: The rotation limiting member 1 is directly installed on the back of the mobile phone protective case 5. Since the rotation limiting member 1 can be rotationally adjusted, the angle of the sliding limiting member 2 can be adjusted accordingly, which is convenient for actual use; the wristband bracket 4 rotatably installed on the sliding limiting member 2 in a damped manner can form a bracket structure for the mobile phone, enabling it to stably support the protective case 5 for use; in addition, the sliding limiting member 2 can be slidably adjusted on the rotation limiting member 1, thus avoiding the bracket structure from blocking the wireless charging area, so there is no need to remove the protective case 5 for wireless charging.

[0038] Furthermore: The rotation limiting member 1 includes a positioning disc 1.1 and a rotating piece 1.2. The positioning disc 1.1 is fixedly installed on the back of the protective case 5, and the rotating piece 1.2 is rotatably installed on the positioning disc 1.1, enabling the rotating piece 1.2 to be rotated and adjusted by 360°, which is convenient for actual use. There is a sliding gap 6 between the rotating piece 1.2 and the back of the protective case 5. A chute 7 is formed on the bottom side of the sliding limiting member 2, and the rotating piece 1.2 is slidably installed in the chute 7, enabling the sliding limiting member 2 to slide on the rotating piece 1.2 and quickly avoid the wireless charging area for use.

[0039] Furthermore: A first circular boss 8 is formed on the positioning disc 1.1, a second circular boss 9 is formed in the middle of the bottom side of the rotating piece 1.2, a rotating hole 10 is formed in the middle of the second circular boss 9, and the first circular boss 8 is rotatably installed in the rotating hole 10.

After the rotating piece 1.2 rotates a certain angle, the gear position clamping block 19 can be clamped in one of the semi-circular clamping grooves 21 for limiting. When a continuous rotating force is applied, the gear position clamping block 19 will disengage from the semi-circular clamping groove 21 and continue to rotate in the rotating hole 10, realizing the positioning during rotation adjustment, making it more comfortable and convenient to use.
