Carrier of portable electronic device

The present invention provides a carrier for a portable electronic device, in particular, a plurality of clamping arms are assembled on a plurality of arms of the base body, and the plurality of clamping bodies are relatively telescopically displaced, and the plurality of clamping bodies can be adjusted to stably hold different sizes. The effect of the portable electronic device, and the positioning portion of the seat can be used to be assembled and disassembled on the preset connecting buckle for the purpose of simple operation.

According to the rapid development of electronic technology and multimedia information, portable electronic devices such as tablet computers, smart phones, and global satellite navigation machines are moving toward light, thin, short, small and powerful functions, mainly with small size. Lightweight, easy to carry and other features, plus soft and hard features continue to innovate, the use of more flexible and practical effects, has become an indispensable part of people's work and life and is widely used.

Moreover, since the use of the portable electronic device must be used through the fingers and the eyes to achieve effective use, if the user is sitting at a certain point or riding in the car, it is not dangerous. However, if the user is walking, even when riding a bicycle, motorcycle, or driving, the portable electronic device is still operating, and it is easy to cause a collision because the line of sight is not focused on the front, especially when riding a bicycle or driving. Operating the electronic device under conditions is more likely to cause death.

Therefore, in order to take into account the safety of driving, but do not want to miss the call Listening, some manufacturers have developed a carrier for the portable electronic device. The carrier is mounted on a bicycle or motorcycle bracket, or inside the vehicle. When the electronic device is mounted on the carrier, The angle and position of the electronic device can be adjusted, so that when the user is in the state of cycling and driving, the electronic device can be stably placed and conveniently viewed by the user, so as to obtain an optimal viewing angle, but the carrier is available for electronic use. The device is placed and positioned, but the volume of the carrier is fixed, and the displacement adjustment of the extension or contraction cannot be performed. Because the size of various electronic devices on the market also varies with the manufacturer, there are also some differences. The actual structure of the carrier cannot be met, and the overall structure is quite unstable. As a result, the electronic device is susceptible to external forces and loose or structural damage occurs, and those who are still engaged in this industry are redesigned to effectively solve it.

Therefore, in view of the above-mentioned problems and deficiencies, the creators have collected relevant information, and through multi-party evaluation and consideration, and through years of experience accumulated in the industry, through continuous trial and modification, the portable electronic device was designed. The new type of bearing seat was born.

The main purpose of the present invention is that the base side surface of the base body has a plurality of arms extending outwardly, and each arm has a joint portion at a side away from the base, and is provided at the bottom of the base for the activity. a plurality of clamping bodies are assembled on the plurality of clamping arms, and a plurality of clamping bodies are disposed on the plurality of clamping arms, and a clamping space for positioning and positioning of the preset portable electronic device is formed between the plurality of clamping bodies, and Each of the bases has abutting portion for a relative telescopic displacement with the engaging portion, and the base portion is provided at the other side of the mating portion for preventing the preset portable electronic device from being separated from the clamping space. The blocking portion of the plurality of clamping bodies can perform a telescopic displacement operation on the plurality of arms according to the size of the electronic device, thereby adjusting the clamping space between the plurality of clamping bodies until the clamping The space for the electronic device to enter and hold, and thus has the effect of firmly clamping portable electronic devices of different sizes, and at the same time achieves the purpose of stable structure and easy operation.

The second purpose of the creation is that the positioning portion of the body is movable to be assembled on the docking seat of the connecting buckle, and the docking seat only needs to pull the buckle on one side to withdraw the positioning portion from the docking seat In order to achieve quick and easy assembly and disassembly.

Another object of the present invention is that the accommodating groove of the base base and the cover body are elastically supported against the elastic member, and the cover body is high above the opening of the accommodating groove before being pressed, The compression deformation of the elastic component is provided for portable electronic devices of different thicknesses, and when the portable electronic device is installed, the portable electronic device can be reduced by the elastic buffering function of the elastic component. The purpose of the vibration generated when the vehicle is running.

A further object of the present invention is that the blocking portion of the plurality of clamping bodies has a floating piece of the elastic piece. When the portable electronic device is installed, the plurality of elastic pieces are generated along the side wall of the portable electronic device. Elastic deformation, that is, it can be used to clamp portable electronic devices of different sizes, so as to achieve the purpose of improving practicality and product competitiveness.
