Description

Positioning component of electronic device

The invention relates to a positioning component which uses a magnetic method to quickly locate and disassemble an electronic device, so as to facilitate carrying, capturing and viewing multimedia images and video at any time. Especially for electronic devices such as mobile phones, tablet computers, digital photo frames, driving recorders, monitors, displays, etc., and relates to an electronic device capable of magnetically adsorbing, positioning, or mutually repelling at a specific angle A positioning assembly that can be separated and removed by the device.

In recent years, with the rapid development of the electronics industry, technology is changing with each passing day, and information products are constantly being introduced. Electronic dictionaries, smart phones, tablet PCs, Pocket PCs, and personal digital assistants ( The invention of portable electronic devices such as PDA (Personal Digital Assistant), digital photo frame or driving recorder makes life more convenient, allowing users to use electronic devices anytime and anywhere, facilitating instant processing, watching videos, receiving emails or Play online games...etc.

When the electronic device is used, it is usually held by hand. However, due to the long-term handheld electronic device, the wrist and fingers of the user are easily sore. Therefore, various brackets for supporting the electronic device exist on the market to facilitate various public occasions. In the middle, the electronic device is placed on the bracket, which not only avoids the user's wrist or finger pain, but also avoids the shaking that occurs when the electronic device is held, and causes the user to suffer from eye fatigue.

It is also known that the bracket of the conventional electronic device usually has an electronic device. a frame body and a support leg for supporting the frame body, so that the bracket can be placed on a table or a chair, and the frame is supported on the table or the chair by the support leg, and the bracket is mostly used for fixing the smart phone. Electronic devices such as tablets, palmtops, or digital photo frames can only be placed on the desktop when they are used, and cannot be fixed to the wall or the car.

Another commercially available stand that can be placed on a wall or placed inside the windshield of a vehicle is mostly used to fix electronic devices such as monitors, monitors, televisions, or driving recorders, and even to fix mobile phones and tablets in the car. For easy operation. The problem with the design of this type of bracket is that in order to prevent the electronic device from falling and being damaged by the bracket, it is fixed with the electronic device by means of a clamp arm or a locking method, so that the user wants to move the electronic device to carry it. When it is necessary, it must be removed from the bracket before it can be carried, which is quite inconvenient to use.

In particular, most of the current electronic products, such as tablet computers or mobile phones, tend to be multi-functional, and the use cases are more diverse. For example, when a tablet computer is used for paperwork or reading in a home or office, it is usually placed at a vertical angle, and when it is carried to a car to watch a movie or multimedia, it is placed horizontally, so that during the operation of the tablet or the mobile phone, It is often necessary to position and disassemble at any time, and to rotate and adjust between the two angles, and currently the commercially available products obviously cannot meet this demand.
