[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-Figure 4 As shown, the present embodiment provides a gearless flexible screen rotating hinge, including an installation component 20, the installation component 20 includes a pair of door panels 8 arranged side by side, a base 2 is provided at the bottom of the two door panels 8, and a pair of shell connecting rods 3 are provided on the side away from each other of the two door panels 8, and the shell connecting rods 3 located on the same door panel 8 are respectively located at two ends away from the door panels 8, and a pair of parallel limit rods 9 are fixedly connected between the two bases 2. Two pairs of symmetrical rocker arms 1 are provided between the two door panels 8, and one end of the two limit rods 9 away from each other is slidably connected with a force sensing component 40, and a transmission component 30 is provided in the force sensing component 40. The installation component 20 is used to fit with the flexible screen, and the transmission component 30 drives the two door panels 8 to open and close synchronously, and then the force sensing component 40 assists the door panels 8 to drive the screen to fold into a water drop shape.

[0026] Working principle: When the gearless flexible screen rotating hinge provided by the utility model is used, the installation component 20 is used to fit with the flexible screen, and the two door panels 8 are driven to open and close synchronously through the transmission component 30, and then the force sensing component 40 assists the door panels 8 to drive the screen to fold into a water drop shape.

[0027] In order to drive the two door panels 8 to open and close synchronously, the transmission assembly 30 includes a pair of gear sliders 4 and a pair of transmission rods 6 slidably connected to the top of the limit rod 9, and a transmission block 5 is provided between the gear slider 4 and the transmission rod 6 located at the top of the same limit rod 9, and the transmission block 5 is slidably connected to the limit rod 9; when it is necessary to drive the mobile phone screen to fold by rotating the door panel 8, the gear slider 4 and the transmission rod 6 slide along the limit rod 9 toward the direction of the other slider and the transmission rod 6, so that the two door panels 8 are bent from the middle part; if the gear slider 4 and the transmission rod 6 slide along the limit rod 9 away from the other slider and the transmission rod 6, the two bent door panels 8 will be driven to open.

[0028] Taking into account the need to assist the door panel 8 in driving the screen to fold into a teardrop shape, the force sensing component 40 includes a slide bar 11 inserted into the sides of the two gear sliders 4, and both ends of the two slide bars 11 are slidably connected to the limit pins 10. A spring 7 is sleeved on the slide bar 11, and the spring 7 is located between the gear slider 4 and the limit pin 10; when the gear slider 4 and the transmission rod 6 slide along the limit rod 9 toward the direction of the other slider and the transmission rod 6, the gear slider 4 drives the spring 7 fixedly connected thereto to stretch, and after being bent into a teardrop shape, the gear slider 4 is engaged with the serrated notch provided at the bottom of the limit pin 10, thereby ensuring that the door panel 8 in the folded state will not be driven to return to its original state by the restoring force of the spring 7, and when the curvature of the bending of the door panel 8 is different, the position where the gear slider 4 is engaged with the serrated notch at the bottom of the limit pin 10 is different.

[0029] In order to ensure the durability of the device, the transmission block 5 is made of high-strength steel and the door panel 8 is made of PC plastic. PC plastic has excellent strength and toughness, and can stretch to a certain extent when subjected to force without being easily broken, so that it has better performance under stress conditions such as impact or extrusion.

[0030] When the gearless flexible screen rotating hinge provided in the utility model is used, the mounting assembly 20 is used to fit with the flexible screen, and the transmission assembly 30 drives the two door panels 8 to open and close synchronously. Specifically, when the mobile phone screen needs to be folded by rotating the door panel 8, the gear slider 4 and the transmission rod 6 slide along the limit rod 9 toward the direction of the other slider and the transmission rod 6, so that the two door panels 8 are bent from the middle part. If the gear slider 4 and the transmission rod 6 slide along the limit rod 9 in the direction away from the other slider and the transmission rod 6, the two bent door panels 8 will be driven to open; The force sensing component 40 assists the door panel 8 in driving the screen to fold into a teardrop shape. Specifically, when the gear slider 4 and the transmission rod 6 slide along the limit rod 9 toward the direction of the other slider and the transmission rod 6, the gear slider 4 drives the spring 7 fixedly connected thereto to stretch. After being bent into a teardrop shape, the gear slider 4 is engaged with the serrated notch at the bottom of the limit bolt 10, thereby ensuring that the door panel 8 in the folded state will not be driven by the restoring force of the spring 7 to restore to its original state. When the curvature of the bending of the door panel 8 is different, the position where the gear slider 4 is engaged with the serrated notch at the bottom of the limit bolt 10 is different.
