Description

Technical Field This invention patent relates to a rollable screen mobile phone. Background Technology Mobile phones, also known as cell phones, ushered in the information age. With scientific advancements, the 4G and 5G era of smartphones has drastically changed our lives. They offer a wide range of functions, including calls, video calls, photography, video recording, payments, news reading, live streaming, browsing, searching, file transfer, editing, gaming, recording, audio transmission, and the installation and use of various software. Mobile phones have become indispensable devices in modern life. From the initial brick-sized "brick" phones to today's tablet, foldable, and ultra-thin models, mobile phones have become increasingly diverse. However, because the screen size requires a certain area, current mobile phone screens remain relatively fixed. No matter how thin a mobile phone becomes, the fixed screen area remains the same, including foldable phones. This makes mobile phones very inconvenient to carry. Furthermore, mobile games have become a social problem of prolonged and addictive gaming, especially among teenagers who can play anytime, anywhere, day and night. Many have neglected their studies as a result, a social issue that the whole society is concerned about and wants to address. This invention addresses the aforementioned problems of mobile phone portability and mobile games by developing a rollable screen phone. It makes the phone more portable, smaller in size, and smaller in area, effectively protecting the main screen from drops and breakage. At the same time, it is not suitable for vigorous pressing and squeezing while playing games, thus solving the social ills of mobile gaming. Because the main screen needs to be opened, stretched, and fixed, and then pushed back and folded after use, it effectively controls the number of times the phone is used for internet browsing, protecting the eyes and reducing radiation, which is beneficial to health. Summary of the Invention

[0001] The purpose of this invention is to provide a rollable screen mobile phone. It uses an ultra-thin flexible screen material. A rollable screen fixing rod secures one side of the flexible screen to a roll, while a rollable screen tensioning rod secures the other side. Through a screen guide groove and a folding screen guide groove, the upper and lower magnetic bead lock plugs inside the tensioning rod are inserted into the magnetic bead lock. The screen is secured by the combined force of the spring tension and magnetic attraction within the magnetic bead lock. Simultaneously, a pull-cordless spring assembly installed inside the roll generates a reverse rotational force when the roll rotates, tightening the phone screen. When not in use, the magnetic bead lock plugs can be pushed open by hand, and the flexible screen is rolled up by the reverse force of the pull-cordless spring assembly. Fold the top and bottom screen guides closed. Incoming calls, notifications, and messages will be displayed on the front screen, and you can write messages, answer calls, and make calls. Because the main screen is rolled up on a cylindrical roll, the phone has a cylindrical or rod-like shape, making it easy to carry. The phone casing is cylindrical, and the cross-section of the casing can be circular, rectangular, elliptical, or regular polygonal. Since the main screen is used in a stretched state, it is not suitable for vigorous pressing or pressing during games. The front screen is a small auxiliary screen, which is not suitable for displaying game screens. Therefore, this phone can effectively prevent game operations.

Use the top plate bolt 2 to connect and fix the top plate 3 to the outer shell 1-17. When using the mobile phone, turn on the power button.The front screen 1-16 can display incoming calls and text messages, and allows users to write on it. It can also answer calls and display the number and symbol keys for making calls. When using the main screen 10-22, pull open the upper and lower folding guide slots at the opening groove 1-14 of the roll-up screen assembly to a 90-degree angle with the outer casing 1-17. Pull out the roll-up extension rod 10-3, allowing the upper magnetic ball lock plug 10-7 and the lower magnetic ball lock plug 10-18 to be inserted into the upper folding guide slot's magnetic ball lock 10-11 respectively. The magnetic ball lock 10-14, which connects to the lower folding screen guide groove, overcomes the reverse pull force generated by the pull cordless spring assembly 17 under the combined action of the ball lock's elasticity and magnetism, and is fixed to the magnetic ball lock. When the main screen 10-22 is retracted, the screen retracting rod 10-3 is pushed back towards the drum by hand. Under the reverse pull force generated by the pull cordless spring assembly 17, the drum 20 rotates and winds the main screen 10-22 onto the drum 20 until both ends of the screen retracting rod 10-3 are stopped by the upper fixed screen guide groove. Stop 10-5 and lower fixed guide screen groove stop 10-21 are blocked. Then, fold the upper folding guide screen groove 10-9 and lower folding guide screen groove 10-16 closed. The upper and lower folding guide screen groove fixing magnets are attracted and fixed to the housing fixing magnet 1-11. Due to frequent use, the reverse tension generated by the non-pull rope spring assembly 17 will weaken, and the two ends of the screen rolling extension rod 10-3 will not touch the upper fixed guide screen groove stop 10-5 and lower fixed guide screen groove stop 10-21. At this time, the rotating screw Turn knob 16-1 until both ends of the screen retraction rod 10-3 touch the upper and lower fixed screen guide groove stop blocks, then close the upper and lower folding screen guide grooves. In addition, when the main screen connection cable 6 rotates in the rotating shaft 7 installed in the roll 20, it will twist, but it will twist until the main screen 10-22 is fixed. When the main screen 10-22 is retracted, the main screen connection cable 6 will return to its original position. Therefore, the rotation of the main screen connection cable 6 in the rotating shaft 7 is a repetitive and limited rotation, which will not damage the main screen connection cable 6. This invention features a small size, portability, and effective protection of the phone's main screen. The main screen is opened when needed and folded away when not in use. Incoming calls, answering calls, sending text messages, and handwritten messages can all be handled on the front screen, ensuring normal phone functionality. This rollable phone allows users to choose between pulling out the main screen from the right or left side, depending on their preference. Because the main screen is supported by a lever, it significantly limits the use of games with intense, frequent screen tapping. It also restricts the opening and closing of the main screen for those who frequently use their phones, reducing opportunities to constantly check the phone. Furthermore, phones with the main screen pulled out from the right require the left hand to hold, while those with the left require the right, making them unsuitable for prolonged screen time. This reduces screen time for those addicted to their phones, effectively limiting the psychological dependence and prolonged exposure to radiation caused by prolonged phone use and mobile game addiction in today's society.

[0006] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. The main screen connection cable and the front screen connection cable are manufactured using existing industry materials according to the structural requirements of the drawings. Various connecting bolts are purchased as standard parts. The springs and non-tension spring fixing shafts are made of metal materials. The upper and lower coaxial connecting pieces are made of copper or metal materials. The housing fixing magnet is made of metal materials. The upper and lower magnetic ball lock plugs and the upper and lower folding guide screen groove magnetic ball locks are common parts in the cabinet industry. Due to the small size of this product, it needs to be customized, but its structure remains the same. It is necessary to magnetize the two matching products. The required magnetic force is calculated based on the tension generated by the non-tension spring and the clamping force of the magnetic ball lock plug generated by the spring inside the ball lock. This ensures the normal fixation of the main screen. For fixing and unplugging the plug, all other parts in the drawings can be manufactured using plastic injection molding or metal materials. The main screen needs to use a thin, flexible screen material, while the front screen can be made from materials currently used in the industry. Since the main screen is rolled up on a spool, there is no limit to the number of times the screen can be damaged by folding. In addition, because the screen area is smaller, the three-dimensional space of the phone is larger, allowing the phone battery to be either square or round, giving the industry more options for production.

Pull the screen retractor 10-3 out of the folding guide slot opening 1-10, insert one end into the upper fixed guide slot 10-4 and let the upper fixed guide slot stop block 10-5 lock the screen retractor 10-3. Insert the other end of the screen retractor 10-3 into the lower fixed guide slot 10-20 and let the lower fixed guide slot stop block 10-21 lock the screen retractor 10-3. Use the fixed guide slot connecting bolt 11 to connect and fix the upper fixed guide slot 10-4 and the lower fixed guide slot 10-20 to the outer shell 1-17. Fold up the upper folding guide slot 10-9 so that the upper folding guide slot fixing magnet 10-10 and the outer shell fixing magnet 1-11 are attracted and fixed. Fold up the lower folding guide slot 10-9. -16 Retract the lower folding screen guide groove fixing magnet 10-15 and the other shell fixing magnet 1-11 to fix them together. Use the top plate bolt 2 to connect and fix the top plate 3 to the outer shell 1-17. When using the mobile phone, turn on the power button. The front screen 1-16 can display incoming calls and text messages. You can write on it and answer incoming calls. It can also display the number keys and symbol keys for making calls. When using the main screen 10-22, pull the upper and lower folding screen guide grooves open at the opening groove 1-14 of the screen roll assembly to form a 90-degree angle with the outer shell 1-17. Pull out the screen roll extension rod 10-3 so that the upper magnetic ball lock plug 10-7 and the lower magnetic ball lock plug 10-18 are respectively inserted into the upper folding screen guide groove magnetic ball lock 10-11 and the lower folding screen guide groove magnetic ball lock 10-11. The ball lock 10-14, under the combined action of the ball lock's elasticity and magnetism, overcomes the reverse pull force generated by the cordless spring assembly 17 and is fixed to the magnetic ball lock. When the main screen 10-22 is retracted, the screen retractor 10-3 is pushed back towards the drum by hand. Under the reverse pull force generated by the cordless spring assembly 17, the drum 20 rotates, winding the main screen 10-22 onto the drum 20 until both ends of the screen retractor 10-3 are blocked by the upper fixed guide groove stop block 10-5 and the lower fixed guide groove stop block 10-21. Then, the upper folding guide groove 10-9 and the lower folding guide groove 10-16 are folded closed, and the upper and lower folding guide groove fixing magnets are attracted and fixed to the housing fixing magnet 1-11. Due to frequent use...The reverse tension generated by the cordless spring assembly 17 will weaken, and the two ends of the screen retractor 10-3 will not touch the upper fixed screen guide groove stop block 10-5 and the lower fixed screen guide groove stop block 10-21. At this time, rotate the screw knob 16-1 until the two ends of the screen retractor 10-3 touch the upper and lower fixed screen guide groove stops, and then close the upper and lower folding screen guide grooves. In addition, the main screen connection cable 6 will twist when it rotates in the rotating shaft 7 installed in the retractor 20, but it will twist until the main screen 10-22 is fixed. When the main screen 10-22 is retracted, the main screen connection cable 6 will return to its original position. Therefore, the rotation of the main screen connection cable 6 in the rotating shaft 7 is a repetitive and limited rotation, which will not damage the main screen connection cable 6.
