In the rapid development of the times, the use of mobile phones has become an indispensable part of people's life behavior. In order to make it more convenient for people to use the mobile phone, the mobile phone bracket has become a good helper. In order to better open the market, the appearance design of mobile phone bracket plays a very important role.

1、 Market Research on mobile phone holder

With the widespread use of mobile phones, people's demand for comfort is also increasing. The types of mobile phone bracket are also dazzling. On the contrary, people aged 18-25 years use the most frequently, and women are more than men. Most of the occupations are school students. The users spend most of their time listening to songs and watching movies. Most people are more receptive to mobile phone holders with relatively small size and easy to carry. The demand reflected in the bracket structure is that It is adjustable and foldable, with additional functions such as stereo, headset winding device, mobile phone lamp, etc. the materials used tend to be plastic, wood, soft rubber / rubber. In the appearance of mobile phone bracket, single color is more easily recognized, and the demand for patterns also accounts for the majority, and more people think that the function is greater than the appearance, and its price acceptance range is between 10-30 yuan. These valuable research results provide a lot of help for our research design.

2、 Investigation on design function of mobile phone bracket

According to the market mobile phone bracket function survey, the design of the appearance structure can be roughly divided into: paste type bracket, planar support, flexible rod bracket, U-shaped bracket, magnetic support, disc suction support, sports support.

Among the numerous mobile phone holders, the most popular choice for customers should be the flexible rod bracket. This type of bracket can release the support of our arm, and it can be widely used and reasonably priced to meet some needs of users. However, it is inconvenient to carry, and the use of the chuck thickness is limited, can not meet the thicker furniture, its material appearance is plastic, the interface is easy to crack, and the service life is general.

The adhesive bracket is simple in design. It is pasted on the back of the mobile phone when used, but it has poor adhesiveness, fixation and service life. And the function is single, easy to leave a gel mark on the mobile phone when it is removed. The finger ring type of the same adhesive bracket has high durability, and the material is generally metallic. It can be used for a long time. However, holding the finger for a long time will cause uncomfortable feeling, and the functionality is the same single. The materials of plane support are mostly plastic, wood and metal, but they can only be used in plane places because of the limitation of their use places.

Compared with these shortcomings, the disk type bracket design is more refined, the bracket is firmly connected with the mobile phone, and the 10000 sentence ball head can adapt to 360 degrees of rotation to meet the use in the car. But the disadvantage is that the price is too high to meet the training needs of many places. Suction cup type bracket, multi-purpose mobile phone, easy to disassemble. However, the range of stretching morning is smaller, which does not satisfy the larger space.

Based on the above research on the advantages and disadvantages of mobile phone bracket hole inspection, in order to meet the needs of a larger number of people, we need to grasp its appearance more accurately, function more perfect and design more refined.

3、 Creative research on new mobile phone bracket

（1） Structure design: the new mobile phone bracket uses a dismembered structure, which divides the whole mobile phone bracket into three parts: mobile phone protective cover, support rod, support and plate. The mobile phone protective cover is designed as a lovely fish shape, and the fish fin is designed on both sides of the mobile phone as the handle of the mobile phone, which is convenient for entertainment. The mobile phone connection table is designed as a 360 degree rotating structure with universal ball head. The support rod is ball type link, which can be bent and folded freely for easy carrying. The support at the bottom of the bracket adopts the working mode of suction cup, which can not only be used in the plane support, but also can be used in the plane support It is used for mobile entertainment. When using the bracket, two supporting claws are wrapped on the railing or shelf to ensure that there is no looseness. The connecting rod can be bent arbitrarily and adjusted to Shuyun's perspective range according to customer's requirements.

（2） In terms of additional functions: we designed a round hole at the top of the mobile phone connection desk to connect the earphone, and open the lighting round hole required by the mobile phone on its back shield, and wrap the headset on the protruding ring; the battery can be installed inside the support rod to be used as a lamp; the flexibility of the mobile phone bracket pole and the function of the ≡ function of the rod can facilitate customers to go out and play Because the rod body is bendable, it can also act as a clothes rack function, which is more convenient for users' work and life.

（3） Shape design: the mobile phone bag is designed in the shape of fish, and the lovely design fits most of the female friends who use the mobile phone bracket: the support rod is made up of a small number of people. I choose to enjoy your eyes. The support claw at the bottom of the mobile phone bracket is based on the frog's body. The bionic design is both beautiful and stable Choose some light and comfortable colors to meet the requirements of most young consumers

（4） Material: stainless steel corrugated pipe, the wire can be bent freely. The joints at both ends are connected with fine thread screw sleeve nuts. The rubber material with high elasticity can protect the mobile phone; the main material of the support rod is ABS and aluminum alloy, and it is composed of engineering plastic and aluminum composite structural parts, which not only ensures the portability, but also ensures the firmness of use, and is safe and reliable.
