Mobile phone case structure

This creation is a mobile phone case, especially containing a structure that can increase the signal of the wireless transmission device of the mobile phone.

The mobile phone was originally an electronic product used for long-distance communication. However, with the development of today's technology, mobile phones have long since shed their thoughts for long-distance communication. Their functions and uses are becoming more and more widespread, one of which is the biggest difference from traditional mobile phones. The function is to use a mobile phone to browse the web. Today's mobile phones can browse the Internet by using wireless networks or mobile mobile networks. Both use antennas to receive or transmit signals, and then use the internal chip processing of the mobile phone to process signals. In addition, the mobile phone can also transmit data via the Bluetooth transmission device. Therefore, the ability of the antenna to receive signals is one of the reasons for determining the speed of the Internet and the speed of the Bluetooth transmission.

In addition, many mobile phone cases that are shaped according to the shape of the outer casing of the mobile phone are sold in the market. The material and design of the mobile phone protective case also affect the ability of the antenna to receive or transmit signals. Therefore, if you can think of both creation and performance Protecting the functions of mobile phones and having the ability to increase the antenna's ability to receive signals is a great boon for mobile phone users today.

And when the Bluetooth transmits data, it does not reduce its interest due to the poor reception of the antenna. By increasing the receiving capability of the antenna, the user can use the wireless transmission device of the mobile phone more conveniently.

The difference between this creation and other mobile phone protective cases is that a pull-tab that can be reciprocated back and forth is arranged on the plane in contact with the mobile phone protective case and the mobile phone, wherein the pull piece is provided with a metal piece. When users use the mobile phone to access the Internet, if they feel that the signal is not good, then pull the pull-tab out to a certain point to increase the antenna receiving capability, so that the Internet speed can be smoother.

The technical means of the creation is to use a metal piece to couple with the antenna of the mobile phone in a non-contact manner, and the distance between the antenna and the metal piece produces the effect of connecting a capacitor in series between the two, thereby changing the receiving of the antenna. The frequency response increases its receiving function. If the distance is set to a resonant frequency, the antenna and the metal piece can be critically coupled to obtain the best transmission signal effect. The metal piece of the present invention is disposed on the pull piece, and the pull piece is slidably moved through the sliding groove design of the body, so the distance between the antenna and the metal piece is changed to change the value of the equivalent capacitor between the two.

The structure of the present invention comprises: a body consisting of a placement surface and a side disposed around an edge of the placement surface, the body is provided with a sliding slot and a hole, the placement surface and the side surface are interconnected and define a a plurality of side holes are disposed on the side; and a pull tab disposed on the body, the pull tabs respectively include a first face and a second face and a metal piece is disposed, the first face facing the space, the first The two faces are opposite to the first face, and the second face is provided with a plurality of grooves, and the pull tab is The chute slides between.

The best use embodiment of this creation is to match the smart phone of the iPhone 5 produced by Apple. The size of the mobile phone is 123.8mm long, 58.6mm wide and 7.6mm high, so the space of the main body can be set to Can accommodate this size. The metal sheet on the tablet can be used to increase the signal of the wireless transmission device, so that the user can use the wireless transmission device to make the wireless transmission device smoother and more stable.

The implementation of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement the present specification after studying the present specification.

Please refer to FIG. 1A and FIG. 1B. For the preferred embodiment of the present invention, the body 1 is formed according to the appearance of the mobile phone to form a protective case for placing the mobile phone. The bottom of the body 1 is a placement surface 11 and a surrounding surface. The portion formed around the periphery 11 is a side surface 12 which is connected to each other and defines a space 13.

The body 1 is formed with a rectangular hole on one side of the placement surface 11 and a sliding rail structure is formed on the side of the hole to form a sliding slot 111. The sliding rail structure is provided with a limiting portion, and the placing surface 11 is additionally formed with a hole 113. After the creation of this creation is combined with the mobile phone, the camera lens of the mobile phone will not be blocked.

The body 1 is formed with a plurality of side holes 121 on the side surface 12 to provide space. When the creation is combined with the mobile phone, the user can press the buttons such as the standby button and the sound control button; and the device such as the earphone and the charger can be inserted.

The pull tab 21 is shaped according to the rectangular shape of the chute 111 and can be formed on the side thereof. The design of the slide rail structure allows the pull tab 21 to slide between the chutes 111 and is constrained via the restricting portion to stay in the position as shown in FIG.

The plane of the position where the pull-tab 21 faces the mobile phone is the first face (the plane shown in the first A-picture); the plane relative to the first face is the second face (the plane shown in the first B-picture). The pull tab 21 is provided with a metal sheet 211 on the first side, wherein the manner of setting is, but not limited to, bonding with an adhesive. The pull tab 21 forms a plurality of grooves 212 on the second side.

It should be understood that the position formed by the body 1 chute is not limited to that shown in FIG. B. In addition, the position of the metal piece is not limited to the first side of the pull tab, and may also be disposed on the pull tab. The second side is either disposed between the first side and the second side.

Please refer to the third figure for the best use embodiment of the present invention. The body 1 is shaped to be placed and covered with a mobile phone 3 having a length of 123.8 mm, a width of 58.6 mm, and a height of 7.6 mm. The mobile phone 3 is provided with a standby button, a sound effect control button, an earphone insertion hole, a charger insertion hole, and the like, and the side holes 121 formed by the side surface 12 of the body 1 are used by the user.

The best use embodiment of this creation is to match the smart phone of the iPhone 5 name produced by Apple. The size of the mobile phone is 123.8mm long, 58.6mm wide and 7.6mm high.
