Detailed Description

The application provides a rotary device and a mobile terminal for the very big folding mobile terminal that reduces is at the in-process of buckling, and the life of flexible screen is prolonged to the power of dragging and the extrusion force of flexible screen.

First, a specific structure of the mobile terminal shown in the present application is exemplarily described below, and the present embodiment does not limit a specific device type of the mobile terminal, for example, the mobile terminal may be a mobile phone, a tablet computer, a keyboard, a vehicle-mounted terminal, and the like.

First, the overall structure of the mobile terminal according to the embodiment will be described with reference to fig. 2 and 3. The mobile terminal shown in this embodiment includes a flexible screen 201, a first housing 202, a second housing 203, and a rotating device 204.

Specifically, the flexible screen 201 shown in this embodiment is a display screen formed by using plastic as a substrate and organic light-emitting diodes (OLEDs) as display materials, which is abbreviated as a flexible display screen 201. Because the plastic is used as the substrate, the plastic can be folded and bent at will, and is very light and thin, and after being connected with circuit signals, images can be displayed. Compared with a traditional screen, the flexible screen has the advantages that the flexible screen is obvious, is lighter and thinner in size and lower in power consumption than a non-flexible screen, the cruising ability of the mobile terminal is improved, and meanwhile, based on the characteristics of flexibility and good flexibility, the durability of the flexible screen is greatly higher than that of the non-flexible screen, and the probability of accidental damage of the mobile terminal is reduced.

Specifically, the first housing 202 is connected to the second housing 203 through the rotating device 204, and the flexible screen 201 is attached to the first housing 202 and the second housing 203, that is, the first housing 202 and the second housing 203 shown in this embodiment are used to support and fix the flexible screen 201.

The various states of the mobile terminal are illustrated in the following figures:

first, as shown in fig. 4, when the mobile terminal is in an unfolded state, the flexible screen 201 is completely unfolded, that is, an included angle between the first housing 202 and the second housing 203 is 180 degrees, a user can view videos and images through the flexible screen 201 and input touch events and the like on the flexible screen 201, and when the user uses the mobile terminal, the user wants to fold the mobile terminal for carrying conveniently, at this time, the user applies an external force to the mobile terminal, the present embodiment does not limit the direction of the external force, as long as the force acts on the first housing 202 and the second housing 203, so that the included angle between the first housing 202 and the second housing 203 is reduced, as shown in fig. 5, the external force drives the first housing 202 and the second housing 203 to rotate around the rotating device 204, so as shown in fig. 5 to 7, in the process that the first housing 202 and the second housing 203 rotate around the rotating device 204, an included angle between the first housing 202 and the second housing 203 gradually decreases until the included angle between the first housing 202 and the second housing 203 is zero degree, so that the mobile terminal is in a folded state.

With the rotating device 204 shown in this embodiment, in the process that the first housing 202 and the second housing 203 rotate around the rotating device 204, the first housing 202 and the second housing 203 retract toward the rotating device 204 until the mobile terminal is completely folded, and the retracted distance of the first housing 202 and the second housing 203 toward the rotating device 204 just compensates for an extra length generated by stretching the flexible screen 201 when the mobile terminal is folded, so that the flexible screen 201 shown in this embodiment is not pulled when the mobile terminal is folded, thereby protecting the flexible screen 201 and effectively prolonging the service life of the flexible screen 201.

The following describes in detail how to avoid stretching the flexible screen 201 by using the mobile terminal shown in the present embodiment;

referring to fig. 5 to 7, in this embodiment, taking the lengths of the first casing 202 and the second casing 203 as L and the width as r as an example, the connection point between the first casing 202 and the second casing 203 is an O point, and then the length of the flexible screen 201 is 2L. In the embodiment of the present application, if the included angle between the first housing 202 and the second housing 203 is θ and γ is an angle complementary to θ during the rotation of the first housing 202 and the second housing 203 around the rotating device 204, an extra length h ═ r (γ/360 ° × 2 pi) is generated between the first housing 202 and the second housing 203 due to the rotation of the first housing 202 and the second housing 203.

If the mobile terminal is in a fully folded state, γ is 180 °, h is r ×, and pi, the flexible screen 201 is stretched due to the extra length generated between the first housing 202 and the second housing 203, and with the mobile terminal of the present embodiment, when the first housing 202 and the second housing 203 rotate around the rotating device 204, the first housing 202 and the second housing 203 retract to the rotating device 204 along with the folding process until being fully folded, and when the mobile terminal is in a fully unfolded state, that is, the total length of the first housing 202 and the second housing 203 is 2L, and when the angle between the first housing 202 and the second housing 203 gradually decreases, the first housing 202 and the second housing 203 retract to the rotating device 204, the mobile terminal shown in this embodiment can ensure that the total length 2L of the first housing 202 and the second housing 203 is unchanged, so that the flexible screen 201 is not pulled, the service life of the flexible screen 201 is effectively prolonged, and the visual effect of the flexible screen 201 is improved because the flexible screen 201 is not pulled.

By using the rotating device 204 shown in this embodiment, when the mobile terminal is folded, the first housing 202 and the second housing 203 are retracted toward the rotating device 204, and the specific structure of the rotating device 204 shown in this embodiment will be described in detail as follows:

Optionally, the abutting arm 705 shown in this embodiment may be in a trapezoid structure, and if it is required to realize an automatic opening and closing function when an included angle between the first housing 202 and the second housing 203 is 20 degrees, when the included angle between the first housing 202 and the second housing 203 is 20 degrees, the abutting piece 702 abuts against the top surface of the abutting arm 705, and the first elastic piece 703 in a compressed state provides a force to the abutting piece 702 toward the rotating shaft 301, so that the abutting piece 702 automatically slides along the waist of the trapezoid abutting arm 705, so that the first connecting plate 403 and the first slider 402 slide relatively until the mobile terminal is in a completely folded state, that is, the included angle between the first housing 202 and the second housing 203 is zero degree.

For another example, if an automatic opening and closing function is required to be realized when an included angle between the first housing 202 and the second housing 203 is 160 degrees, when the included angle between the first housing 202 and the second housing 203 is 160 degrees, the abutting piece 702 abuts against the top surface of the abutting arm 705, the first elastic piece 703 in a compressed state applies a force to the abutting piece 702 toward the direction of the rotating shaft 301, so that the abutting piece 702 automatically slides along the waist of the trapezoidal abutting arm 705, so that the first connecting plate 403 and the first slider 402 slide relatively until the mobile terminal is in a fully expanded state, that is, the included angle between the first housing 202 and the second housing 203 is 180 degrees.

When the first convex tooth 805 abuts against the second convex tooth 806, the second elastic element 804 is in a compressed state, and the second elastic element 804 in the compressed state is used for driving the first connecting rod 802 and the rotating element 803 to rotate so as to generate a rotation torque, and the rotation torque is used for enabling the first connecting plate 403 and the first sliding block 402 to slide relatively.

If it is required to realize the automatic opening and closing function when the included angle between the first housing 202 and the second housing 203 is 20 degrees, the first teeth 805 abut against the second teeth 806, and the second elastic member 804 in a compressed state drives the first connecting rod 802 and the rotating member 803 to rotate to generate a rotation torque, so that the first connecting plate 403 and the first slider 402 slide relatively until the mobile terminal is in a completely folded state, that is, the included angle between the first housing 202 and the second housing 203 is zero degree.

For another example, if it is required to realize the automatic opening and closing function when the included angle between the first housing 202 and the second housing 203 is 160 degrees, the first protruding tooth 805 abuts against the second protruding tooth 806, and the second elastic member 804 in the compressed state drives the first connecting rod 802 and the rotating member 803 to rotate so as to generate a rotation torque, so that the first connecting plate 403 and the first slider 402 slide relatively until the mobile terminal is in the fully expanded state, that is, the included angle between the first housing 202 and the second housing 203 is 180 degrees.

The mobile terminal shown in this embodiment can also implement a synchronization function, where the synchronization function shown in this embodiment means that when a user applies a force to the first housing 202 to rotate the first housing 202 around the rotating shaft 301, even if the user does not apply a force to the second housing 203, the second housing 203 still rotates around the rotating shaft 301, and the speed at which the first housing 202 rotates around the rotating shaft 301 is the same as the speed at which the second housing 203 rotates around the rotating shaft 201.

The specific number of the first synchronization protrusions 905 and the second synchronization protrusions 906 is not limited in this embodiment, and the rotation angles of the third connecting rod 903 and the fourth connecting rod 904 may be changed the same by sliding the first synchronization protrusions 905 and the second synchronization protrusions 906, so that in the folding or extending process of the mobile terminal, the angle between the first housing 202 and the rotating shaft 301 is the same as the angle between the second housing 203 and the rotating shaft 301, thereby effectively ensuring the synchronous motion between the first housing 202 and the second housing 203 in the folding or extending process of the mobile terminal.

In order to fix the mobile terminal at any angle during the folding or unfolding process, for example, when the mobile terminal is folded and the angle between the first housing 202 and the second housing 203 is 150 degrees, if the user does not continuously apply a force on the mobile terminal, the mobile terminal can maintain the fixed state between the first housing 202 and the second housing 203 at 150 degrees, the synchronizing assembly 900 in this embodiment further includes a damping sleeve 909, the damping sleeve 909 is disposed on the outer peripheral wall of the third connecting rod 903 and the fourth connecting rod 904, so that the damping sleeve 909 is in contact with the outer peripheral wall of the third connecting rod 903 and the fourth connecting rod 904, and when the third connecting rod 903 and the fourth connecting rod 904 rotate, the damping sleeve 909 generates a damping force for reducing the rotation speed of the third connecting rod 903 and the fourth connecting rod 904, the damping force can stop the rotation of the third connecting rod 903 and the fourth connecting rod 904 without the user applying any force, and the first housing 202 and the second housing 203 will keep the current included angle.
