Abstract

The mobile phone of folding screen is rotatablely connected by upper-lower casing by shaft, and the half of a flexible screen is bonded with the outer surface of upper housing and is fixed together, the other half is bonded but is not fixed with the outer surface of lower case.Side of the lower case far from shaft is connect with flexible screen by an elastic telescopic film.The upper and lower ends of upper housing have baffle, and there is cylindrical body in one end of lower case, there is shaft on cylindrical body, and lower case is rotatablely connected by shaft and upper housing.

Description

A kind of mobile phone of folding screen

Technical field

The present invention relates to a kind of mobile phones of folding screen, belong to field of communication technology.

Background technique

Smart phone is means of communication indispensable in people's life.It is as big as possible in order to be obtained with small size as far as possible Screen display area, there is the concept mobile phone of various folding screens.They are all based on OLED Organic Light Emitting Diode skill The flexible screen of art and design.But the concept mobile phone of current folding screen is mostly directly by screen doubling, radius bend The small center line section for being easily damaged screen.

Summary of the invention

The purpose of the invention patent is to provide a kind of mobile phone of folding screen, the flexible screen with adaptivity deformation Curtain, it may be convenient to realize the conversion between becoming smaller that becomes larger of screen.

The present invention is achieved by the following technical solutions: the mobile phone of folding screen is rotated by upper-lower casing by shaft It is formed by connecting, the half of a flexible screen is bonded with the outer surface of upper housing and is fixed together, the other half is outer with lower case Surface is bonded but is not fixed.Side of the lower case far from shaft is connect with flexible screen by an elastic telescopic film.Upper housing Upper and lower ends have baffle, there is cylindrical body in one end of lower case, there is shaft on cylindrical body, and lower case is turned by shaft and upper housing Dynamic connection.

The invention has the beneficial effects that can be by the screen of folding cell phone, volume reduces when realizing carrying, makes Used time, the purpose that display area can be become larger by the way that upper-lower casing is unfolded realize bigger display surface with small outer dimension Product.

Specific embodiment

In Fig. 1, the main body of the mobile phone of folding screen of the present invention is that upper housing 1 and lower case 2 form, upper lower casing There are the circuit board and battery of smart phone in vivo, can relatively rotate between them, and pass through winding displacement flexible conduction telecommunications Number.The working principle of smart phone is not described in detail by the present invention, and electric principle and existing smart phone are just the same.Upper housing 1 it is upper Surface and the lower surface of lower case 2 are all defined as outer surface.At which in flat, when such as Fig. 3 and two shells it is outer Surface is all upward, becomes upper surface.In Fig. 1, the half of flexible screen 3 is located at the outer surface of upper housing 1.This is partly defined as soft The area A of property screen 3.In Fig. 2, the other half of flexible screen 3 is located at the outer surface of lower case 2, this is partly defined as flexible screen 3 The area B.Camera 4 is located at the top of upper housing 1, as the position of existing mobile phone.

The area A of flexible screen 3 is bonded with the outer surface of upper housing 1 to be fixed together, and is relatively free of the freedom of movement Degree.The area B of flexible screen 3 and the outer surface of lower case 2 are to be bonded but unfixed, can be slided relatively.And lower case 2 A side far from shaft is connect with flexible screen 3 by an elastic stretching film 5.Elastic stretching film 5 is Elastic plastic-rubber material The film of strip made of expecting, can allow 3 moment of flexible screen to be in tensioning state.In Fig. 1 and Fig. 2 state, mobile phone The presence of all flexible screen 3 of front-back can use when common mobile phone, and realize double-sided display or even a side Also there is display function in face.

In Fig. 3, when upper housing 1 and lower case 2, which relatively rotate 180 degree, becomes flat, the area A, B of flexible screen 3 Become flat, display area increasing is twice.Fig. 4 can be seen that the two of upper housing 1 and lower case 2 after removing flexible screen 3 A outer surface pieces together a complete plane, can be very good overleaf to support flexible screen 3.Because present mobile phone is all Touch screen, the supporting surface of flexible screen 3 must be cannot indent and convex plane, just can preferably realize touching manipulation.

As can be seen that the upper and lower ends of upper housing 1 have baffle 6 in Fig. 5, can be coated in the state that upper-lower casing merges Lower case 2.Two axis holes 7 have also been oppositely arranged on upper lower baffle plate 6.The side of lower case 2 being rotatablely connected with upper housing 1 has One cylindrical body 8.Flexible screen 3 is to rotate when rotating around this cylindrical body 8, thus and biggish folding fixed with size Curved radius is hardly damaged flexible screen 3.There is axis 9 at the both ends of cylindrical body 8.The axis 9 and upper housing 1 that upper-lower casing passes through lower case 2 Axis hole 7 cooperation be rotatably connected.Upper-lower casing realizes opposite around the rotation of axis 9.

Fig. 6 can be seen that in the state that upper-lower casing merges, and flexible screen 3 is to be fitted in upper housing 1 and lower case 2 On the cylindrical body 8 of outer surface and lower case 2.The presence of elastic stretching film 5 is just to compensate for during phone folded, The flexible screen 3 in a part of area B occupied by cylindrical body 8.The width of 5 exposed parts of elastic stretching film is equal to the week of cylindrical body 8 Long half.If a flange 10 is arranged beside 2 elastic stretching film 5 of lower case, a part of elastic stretching film can be covered in 5, if the width of flange 10 is equal to the half of the perimeter of cylindrical body 8, can be completely covered by when upper-lower casing merges Elastic stretching film 5.

In Fig. 7, if flexible screen 3 further extends to both sides, by the distal shaft at the distal shaft end of upper housing 1 and lower case 2 End, that is, their side cladding are got up, so that it may form side screen.In order to allow flexible screen 3 radius bend as far as possible Greatly, the side of two shells can be arc-shaped, as shown in the figure.In this way, elastic stretching film 5 can be hidden into lower case 2 The back side.Whether upper-lower casing is in merging phase or unfolded state, all can't see the presence of elastic stretching film 5 from front.

Claims

1. a kind of mobile phone of folding screen, it is characterized in that: being made of upper housing and lower case, upper housing upper and lower ends have gear Plate is provided with opposite axis hole on baffle, and the side of lower case is provided with cylindrical body, and there is shaft at cylindrical body both ends, lower case The shaft hole matching of shaft and upper housing realizes that the rotation connection of upper-lower casing, the outer surface fixation of upper housing have been bonded flexible screen One side of something of curtain, the outer surface of lower case are bonded but are not fixed, the one of the separate cylindrical body of lower case with other half of flexible screen A side is linked together by elastic telescopic film and unfixed half of flexible screen, and elastic telescopic film is made of Elastic plastic-rubber Strip film.
