[0044] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0045] Reference below Figure 1-Figure 12The display terminal 100 according to the embodiment of the present invention is described.

[0046] Combination Figure 1-Figure 3 As shown, the display terminal 100 according to an embodiment of the present invention may mainly include: a shell 10, a flexible display screen 20, a transmission mechanism 30 and an inner pulling mechanism 40. The shell 10 includes: a first side shell 11, a second side shell 12 and a middle shell 13. The first side shell 11 and the second side shell 12 are respectively arranged on both sides of the middle shell 13. The flexible display screen 20 is arranged on the first side shell 11 and the second side shell 12. The transmission mechanism 30 is arranged on the middle shell 13. The transmission mechanism 30 is respectively matched with the first side shell 11 and the second side shell 12 in transmission. The inner pulling mechanism 40 is arranged between the middle shell 13 and the flexible display screen 20. The inner pulling mechanism 40 is also matched with the transmission mechanism 30 in transmission, so that when the first side shell 11 and the second side shell 12 are folded relative to the middle shell 13, the inner pulling mechanism 40 pulls the middle part of the flexible display screen 20 close to the middle shell 13.

[0047] Specifically, the first side shell 11 and the second side shell 12 are respectively arranged on both sides of the middle shell 13, and the flexible display screen 20 is arranged on the first side shell 11 and the second side shell 12. When the user wants to drive the flexible display screen 20 to fold and close, the user can drive the first side shell 11 and the second side shell 12 to rotate relative to the middle shell 13, and the driving force will be first transmitted to the transmission mechanism 30. The transmission mechanism 30 can transmit the user's driving force to the inner pulling mechanism 40. After receiving the driving force, the inner pulling mechanism 40 pulls the middle part of the flexible display screen 20 close to the middle shell 13, thereby realizing the folding and closing of the flexible display screen 20. In this way, not only can the folding of the flexible display screen 20 be smoother and more stable, but also during the folding process, the connection between the flexible display screen 20 and the first side shell 11 and the second side shell 12 will not be pulled or compressed to deform, causing damage, so that the reliability of the flexible display screen 20 can be improved, the service life of the flexible display screen 20 can be improved, and thus the user experience can be improved.

[0048] Therefore, when the first side shell 11 and the second side shell 12 are folded relative to the middle shell 13, the inner pulling mechanism 40 pulls the middle part of the flexible display screen 20 close to the middle shell 13, which can avoid deformation and pulling of the flexible display screen 20 during the folding and closing process, and can improve the structural reliability of the display terminal 100.

[0049] Combination Figure 3 , Figure 6 and Figure 8As shown, the inner pulling mechanism 40 includes: a screen side mounting component 41, a first shell side mounting component 42, a second shell side mounting component 43 and an inner pulling member 44. The screen side mounting component 41 is arranged in the middle of the back side of the flexible display screen 20, the first shell side mounting component 42 and the second shell side mounting component 43 are respectively movably arranged in the middle shell 13, the first shell side mounting component 42 and the second shell side mounting component 43 are respectively located on both sides of the screen side mounting component 41, the first shell side mounting component 42 and the second shell side mounting component 43 are respectively matched with the transmission mechanism 30 for transmission, and the inner pulling member 44 is arranged between the first shell side mounting component 42, the second shell side mounting component 43 and the screen side mounting component 41 to pull the flexible display screen 20 through the screen side mounting component 41.

[0050] Specifically, when the user wants to drive the flexible display screen 20 to fold and close, the user can drive the first side shell 11 and the second side shell 12 to rotate relative to the middle shell 13, and the driving force is first transmitted to the transmission mechanism 30, and the transmission mechanism 30 can transmit the user's driving force to the first shell side mounting component 42 and the second shell side mounting component 43. Since the inner pull member 44 is arranged between the first shell side mounting component 42, the second shell side mounting component 43 and the screen side mounting component 41, the first shell side mounting component 42 and the second shell side mounting component 43 can transmit the driving force to the inner pull member 44, and since the inner pull member 44 and the screen side mounting component 41 are both on the back of the flexible display screen 20, it should be noted that the front side of the flexible display screen 20 is the display terminal. When the end 100 is normally unfolded, the flexible display screen 20 displays an image and faces one side surface of the user, and the back side of the flexible display screen 20 is the side surface of the flexible display screen 20 away from the user. The inner pull member 44 will move on the back side of the flexible display screen 20 toward the direction away from the flexible display screen 20, so that the inner pull member 44 can drive the screen side mounting assembly 41 to fold and close, thereby making the flexible display screen 20 have a tendency to fold and close. Since the flexible display screen 20 is arranged on the first side shell 11 and the second side shell 12, the first side shell 11 and the second side shell 12 can be rotated relative to the middle shell 13, and the inner pull member 44 will simultaneously drive the flexible display screen 20, the first side shell 11 and the second side shell 12 to fold and close and rotate relative to the middle shell 13.

[0051] Such a configuration can not only ensure the stability and reliability of driving force transmission, but also prevent the connection between the flexible display screen 20 and the first side shell 11 and the second side shell 12 from being pulled or deformed when the flexible display screen 20 is folded. This can reduce the risk of deformation of the appearance of the flexible display screen 20, while ensuring the appearance integrity of the flexible display screen 20 in any state.

[0052] Combination Figure 3 , Figure 6 , Figure 8 and Fig.12As shown, the screen side mounting assembly 41 may mainly include: a screen side mounting member 411 and a screen side pull rod 412. The screen side mounting member 411 is arranged at the middle of the back of the flexible display screen 20, the screen side pull rod 412 is arranged on the screen side mounting member 411, and the middle of the inner pull member 44 is arranged on the screen side pull rod 412. Specifically, the inner pull member 44 may drive the screen side pull rod 412 to move downward while moving downward. Since the screen side pull rod 412 is arranged on the screen side mounting member 411, and the screen side mounting member 411 is arranged at the middle of the back of the flexible display screen 20, the screen side pull rod 412 will drive the screen side mounting member 411 to close inward, so that the screen side mounting member 411 drives the parts of the flexible display screen 20 located on both sides of the screen side pull rod 412 to close toward the middle, so that the flexible display screen 20 can be stably and smoothly folded, which can further improve the reliability of the folding of the flexible display screen 20.

[0053] Combination Figure 3 , Figure 6 , Figure 8 and Fig.12 As shown, the screen side mounting member 411 is a first adhesive tape, the two ends of the first adhesive tape are bonded to the back of the flexible display screen 20, the middle of the first adhesive tape is bonded to the screen side tie rod 412, and the inner tie member 44 is a second adhesive tape, the ends and the middle of the second adhesive tape are provided with spaced adhesive layers, the adhesive layer at the end of the second adhesive tape is bonded to the first shell side tie rod 422, and the adhesive layer at the middle of the second adhesive tape is bonded to the screen side tie rod 412. Specifically, the screen side mounting member 411 is set as the first adhesive tape, and the two ends of the first adhesive tape are bonded to the back of the flexible display screen 20, and the middle of the first adhesive tape is bonded to the screen side tie rod 412, so that not only the downward movement of the screen side tie rod 412 can drive the two ends of the first adhesive tape to close inward, thereby driving the flexible display screen 20 to close inward, but also the connection and fixation of the screen side mounting member 411 and the flexible display screen 20 will not cause damage to the flexible display screen 20, so that the structural reliability of the display terminal 100 can be improved.

[0054] Furthermore, by providing spaced adhesive layers at the end and the middle of the second tape, the adhesive layer at the end of the second tape can be bonded to the first shell side pull rod 422, and the adhesive layer in the middle of the second tape can be bonded to the screen side pull rod 412. In this way, not only can the downward movement of the first shell side pull rod 422 cause the middle of the second tape to drive the two sides of the second tape to close toward the middle, thereby allowing the flexible display screen 20 to fold and close toward the middle, but also the structure of the second tape itself can be reliable while ensuring that the folding of the flexible display screen 20 driven by the second tape is stable and reliable.

[0055] In addition, the screen side mounting member 411 is set as the first tape, and the inner pull member 44 is set as the second tape. This can simplify the structure of the screen side mounting member 411 and the inner pull member 44, reduce the space occupied by the screen side mounting member 411 and the inner pull member 44, and allow the flexible display screen 20 to make more full use of the space to sink, thereby reducing the occupied shell space and saving precious space inside the display terminal 100.

[0056] Combination Figure 3 , Figure 6 and Figure 8 As shown, the first shell side mounting assembly 42 and the second shell side mounting assembly 43 both include: a shell side mounting member 421 and a first shell side pull rod 422, the shell side mounting member 421 is in transmission cooperation with the transmission mechanism 30, the first shell side pull rod 422 is arranged on the shell side mounting member 421, and the end of the inner pull member 44 is arranged on the first shell side pull rod 422. Specifically, the shell side mounting member 421 is matched with the transmission mechanism 30 for transmission, and the transmission mechanism 30 can first transmit the driving force to the shell side mounting member 421, and the shell side mounting member 421 will rotate under the drive of the transmission mechanism 30. Since the first shell side pull rod 422 is arranged on the shell side mounting member 421, the transmission of the shell side mounting member 421 can drive the rotation of the first shell side pull rod 422. Since the end of the inner pull member 44 is arranged on the first shell side pull rod 422, the rotation of the first shell side pull rod 422 can drive the inner pull member 44 to move downward. This can not only simplify the structural design of the first shell side mounting component 42 and the second shell side mounting component 43, but also make the transmission of force in the first shell side mounting component 42 and the second shell side mounting component 43 simpler, more direct, stable and reliable, which can further optimize the structural design of the first shell side mounting component 42 and the second shell side mounting component 43.

[0057] Combination Figure 8 and Fig. 9 , Fig.12 As shown, the shell side mounting member 421 can mainly include: a first transmission part 4211 and a second transmission part 4212, the first transmission part 4211 is in transmission cooperation with the transmission mechanism 30, the second transmission part 4212 is biased on the first transmission part 4211, and the first shell side pull rod 422 is arranged on the second transmission part 4212. Specifically, the first transmission part 4211 is in transmission cooperation with the transmission mechanism 30, the second transmission part 4212 is biased on the first transmission part 4211, and the first shell side pull rod 422 is arranged on the second transmission part 4212, so that the rotation of the first shell side pull rod 422 arranged on the second transmission part 4212 can greatly drive the inner pull member 44 to move downward under the premise of ensuring the transmission between the transmission mechanism 30 and the first transmission part 4211 is stable and reliable, so that the stability and reliability of the driving of the inner pull member 44 by the shell side mounting member 421 can be improved under the premise of ensuring the simple structure of the shell side mounting member 421.

[0058] Combination Figure 3 , Figure 6 , Figure 8 and Fig.12 As shown, the first shell side mounting assembly 42 and the second shell side mounting assembly 43 both further include: a second shell side tie rod 431, which is arranged on the shell side mounting member 421, and the second shell side tie rod 431 is arranged at intervals from the first shell side tie rod 422, and the end of the inner tie rod 44 passes through the gap between the first shell side tie rod 422 and the second shell side tie rod 431. Specifically, the second shell side tie rod 431 is arranged outside the first shell side tie rod 422, and the end of the inner tie rod passes through the gap between the first shell side tie rod 422 and the second shell side tie rod 431. The second shell side tie rod 431 can improve the stability and reliability of the rotation of the first shell side tie rod 422, thereby making the movement of the inner tie rod 44 more stable, and further improving the reliability of the folding and closing of the flexible display screen 20.

[0059] Combination Figure 3 , Figure 6 , Figure 8 and Fig.12 As shown, there are multiple screen side mounting components 41, and the multiple screen side mounting components 41 are arranged at intervals on the back of the flexible display screen 20. There are multiple inner pullers 44, and the middle parts of the multiple inner pullers 44 correspond to the multiple screen side mounting components 41 one by one. The two ends of the multiple inner pullers 44 are respectively arranged on the first shell side mounting component 42 and the second shell side mounting component 43. Specifically, the screen side mounting components 41 are arranged in multiple numbers, and the multiple screen side mounting components 41 are arranged at intervals on the back of the flexible display screen 20. The inner pullers 44 are also arranged in multiple numbers, and the multiple inner pullers 44 are arranged in one-to-one correspondence with the multiple screen side mounting components 41. In this way, not only the folding and closing speed of the flexible display screen 20 can be improved, but also the folding and closing force of the flexible display screen 20 can be more uniform, thereby improving the structural reliability of the display terminal 100.

[0060] Combination Figure 3 and Figure 8As shown, the display terminal 100 may also mainly include: a first supporting mechanism 50, a first elastic screen-stretching mechanism 60, a second supporting mechanism 51 and a second elastic screen-stretching mechanism 61, wherein the first supporting mechanism 50 is supported on the middle part of the back side of the flexible display screen 20, one end of the first supporting mechanism 50 is rotatably arranged on one side of the middle shell 13, the first elastic screen-stretching mechanism 60 is arranged on the first side shell 11, and the other end of the first supporting mechanism 50 is slidably arranged on the first elastic screen-stretching mechanism 60 to elastically tighten the flexible display screen 20, and the second supporting mechanism 51 is supported on the middle part of the back side of the flexible display screen 20, one end of the second supporting mechanism 51 is rotatably arranged on the other side of the middle shell 13, the second elastic screen-stretching mechanism 61 is arranged on the second side shell 12, and the other end of the second supporting mechanism 51 is slidably arranged on the second elastic screen-stretching mechanism 61 to elastically tighten the flexible display screen 20.

[0061] Specifically, the first support mechanism 50 and the second support mechanism 51 are both arranged in the middle part of the back side of the flexible display screen 20, and the first support mechanism 50 and the second support mechanism 51 are respectively arranged on both sides of the middle shell 13. In this way, when the user folds the flexible display screen 20, the first support mechanism 50 and the second support mechanism 51 can respectively support the positions of the flexible display screen 20 corresponding to the two sides of the middle shell 13, and the first support mechanism 50 and the second support mechanism 51 can construct an accommodating space for making the middle part of the flexible display screen 20 close to the middle shell 13 during the folding and closing process, so that the folding of the flexible display screen 20 can be more stable and reliable.

[0062] Furthermore, the first elastic screen-stretching mechanism 60 is arranged on the first side shell 11, the other end of the first support mechanism 50 is slidably arranged on the first elastic screen-stretching mechanism 60, the second elastic screen-stretching mechanism 61 is arranged on the second side shell 12, and the other end of the second support mechanism 51 is slidably arranged on the second elastic screen-stretching mechanism 61. Specifically, the other end of the first supporting mechanism 50 is slidably disposed on the first elastic screen-stretching mechanism 60, and the other end of the second supporting mechanism 51 is slidably disposed on the second elastic screen-stretching mechanism 61. When the user folds and closes the flexible display screen 20, the flexible display screen 20 can be folded and closed following the rotation of the first side shell 11 and the second side shell 12 relative to the middle shell 13. During this process, the first elastic screen-stretching mechanism 60 can slide relative to the first supporting mechanism 50, and the second elastic screen-stretching mechanism 61 can slide relative to the second supporting mechanism 51. Since the first elastic screen-stretching mechanism 60 is disposed on the first side shell 11 and the second elastic screen-stretching mechanism 61 is disposed on the second side shell 12, the sliding of the other ends of the first elastic screen-stretching mechanism 60 and the second elastic screen-stretching mechanism 61 can form a folding and making way space for the flexible display screen 20, can elastically tighten the flexible display screen 20, and further can prevent the connection between the flexible display screen 20 and the first side shell 11 and the second side shell 12 from being pulled and deformed, thereby further improving the structural reliability of the display terminal 100.

[0063] Combination Figure 8 and Fig.10As shown, the first elastic screen-tensioning mechanism 60 and the second elastic screen-tensioning mechanism 61 both include: a first mounting member 611, a second mounting member 612 and a first elastic member 613, wherein the first mounting member 611 is arranged on the first side shell 11 or the second side shell 12, the second mounting member 612 is provided with a first slide groove 6121, the other end of the first support mechanism 50 or the second support mechanism 51 can be slidably arranged in the first slide groove 6121, and the first elastic member 613 is arranged between the first mounting member 611 and the second mounting member 612. Specifically, during the folding and closing process of the flexible display screen 20, since the other end of the first supporting mechanism 50 or the second supporting mechanism 51 can be slidably arranged in the first sliding groove 6121, the second mounting member 612 can move relative to the first supporting mechanism 50 and the second supporting mechanism 51 in a direction away from the middle shell 13, and a first elastic member 613 is arranged between the first mounting member 611 and the second mounting member 612. The movement of the second mounting member 612 relative to the first supporting mechanism 50 and the second supporting mechanism 51 can drive the first mounting member 611 to move elastically. Since the first mounting member 611 is arranged on the first side shell 11 and the second side shell 12, the second mounting member 612 can drive the first side shell 11 and the second side shell 12 to move in a direction away from the middle shell 13, thereby tightening the flexible display screen 20 connected to the first side shell 11 and the second side shell 12. In this way, not only can the first elastic screen-stretching mechanism 60 and the second elastic screen-stretching mechanism 61 stabilize the tightening of the flexible display screen 20, but also the structural design of the first elastic screen-stretching mechanism 60 and the second elastic screen-stretching mechanism 61 can be simplified.

[0064] Combination Figure 8 and Fig.10 As shown, the first mounting member 611 is provided with a first sliding portion 6111, the second mounting member 612 is provided with a second sliding portion 6122, the first sliding portion 6111 and the second sliding portion 6122 are slidably matched, the first mounting member 611 is provided with a first limiting portion 6112, the second mounting member 612 is provided with a second limiting portion 6123, and the first limiting portion 6112 is movably arranged in the second limiting portion 6123. Specifically, through the sliding cooperation of the first sliding portion 6111 and the second sliding portion 6122, the first mounting member 611 can slide smoothly and reliably relative to the second mounting member 612, so that the stability of the first elastic screen-stretching mechanism 60 and the second elastic screen-stretching mechanism 61 on tightening the flexible display screen 20 can be improved, and the first elastic screen-stretching mechanism 60 and the second elastic screen-stretching mechanism 61 can be prevented from damaging the flexible display screen 20.

[0065] Combination Figure 5 and Figure 7As shown, the display terminal 100 may also mainly include: a first unfolding and holding mechanism 70 and a second unfolding and holding mechanism 71, the first unfolding and holding mechanism 70 is arranged on the second mounting member 612 of the first elastic screen-tensioning mechanism 60, the first unfolding and holding mechanism 70 is in transmission cooperation with the transmission mechanism 30, the second unfolding and holding mechanism 71 is arranged on the second mounting member 612 of the first elastic screen-tensioning mechanism 60, and the second unfolding and holding mechanism 71 is in transmission cooperation with the transmission mechanism 30. Specifically, the first unfolding and holding mechanism 70 is arranged on the second mounting piece 612 of the first elastic screen-tensioning mechanism 60, and the second unfolding and holding mechanism 71 is arranged on the second mounting piece 612 of the first elastic screen-tensioning mechanism 60. In the process of unfolding the flexible display screen 20 from the folded state, when the flexible display screen 20 is unfolded to a certain angle and the user removes the external force, the first unfolding and holding mechanism 70 and the second unfolding and holding mechanism 71 can control the second mounting piece 612 to keep the flexible display screen 20 at this angle. This can not only meet the user's requirements for the use of the flexible display screen 20 at different unfolding angles, but also enhance the user's use experience of the display terminal 100, and also make the flexible display screen 20 unfold more stably and smoothly in the process of unfolding from the folded state.

[0066] Combination Figure 5 and Figure 7 As shown, the first unfolding and holding mechanism 70 and the second unfolding and holding mechanism 71 both include: a bracket 711, a cam 712, a cam limiter 713 and a second elastic member 714, wherein the bracket 711 is arranged on the second mounting member 612, the cam 712 is arranged on the middle shell 13 and is located in the bracket 711, the cam limiter 713 is movably arranged in the bracket 711, the cam limiter 713 is limitedly cooperated with the cam 712, the second elastic member 714 is arranged in the bracket 711, and the second elastic member 714 abuts against the cam limiter 713. Specifically, when the flexible display screen 20 is unfolded from a folded state, the bracket 711 will rotate with the second mounting member 612 relative to the middle shell 13, and the cam limiter 713 in the bracket 711 will cooperate with the cam 712 on the middle shell 13 for limiting. By setting the surfaces of the cam 712 and the cam limiter 713 in limiting contact at a relevant angle, the cam 712 can drive the cam limiter 713 to squeeze the second elastic member 714, so that the elastic force generated by the second elastic member 714 provides the first unfolding and holding mechanism 70 and the second unfolding and holding mechanism 71 with holding force. In this way, not only can the structures of the first unfolding and holding mechanism 70 and the second unfolding and holding mechanism 71 be simple, but also the holding effect of the first unfolding and holding mechanism 70 and the second unfolding and holding mechanism 71 on the second mounting member 612 and the first elastic screen-tensioning mechanism 60 and the second elastic screen-tensioning mechanism 61 corresponding to the second mounting member 612 can be made more stable and reliable, so that the structural design of the display terminal 100 can be further optimized.

[0067] Combination Figure 4 , Figure 8 and Fig. 9 As shown, the transmission mechanism 30 includes: a base 31, two driving gears 32 and at least two driven gears 33, the base 31 is fixed on the middle shell 13, the cam 712 is fixed on one side of the base 31, the two driving gears 32 and at least two driven gears 33 are arranged on the other side of the base 31, the two driving gears 32 and the two brackets 711 rotate synchronously, and the at least two driven gears 33 are meshed between the two driving gears 32. Specifically, the base 31 is arranged on the middle shell 13, and the cam 712 is fixed on one side of the base 31, and the two driving gears 32 and at least two driven gears 33 are arranged on the other side of the base 31, so that not only the installation setting of the cam 712 can be stable and reliable, but also the limiting cooperation between the cam 712 and the cam stopper 713 can be more stable and reliable.

[0068] Furthermore, the two driving gears 32 and the two brackets 711 are rotated synchronously, and the two driven gears 33 are meshed between the two driving gears 32. In this way, when the user applies force to one of the first side shell 11 and the second side shell 12 to fold and close relative to the middle shell 13, one of the two driving gears 32 can transmit the driving force to the other of the two driving gears 32 through at least two driven gears 33, so that the other of the first side shell 11 and the second side shell 12 will also be folded and closed relative to the middle shell 13, which can facilitate the user's operation. In addition, in order to ensure that the two driving gears 32 have the same direction of rotation, at least two driven gears 33 need to be set to an even number.
