[0034] To make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] As Figures 1 to 3 shown, an embodiment of the present invention provides a display terminal, which includes a first display component 10, a second display component 20 and a rotating connection body 30. Among them, the rotating connection body 30 includes a rotating body 31 and a rotating shaft 32 located inside the rotating body 31. The rotating shaft 32 is fixedly connected to the second display component 20. A first sliding groove 11 is provided on the first display component 10. The rotating body 31 is located in the first sliding groove 11 and can slide along the axial direction of the rotating shaft 32.

[0036] In this embodiment, the above-mentioned rotating shaft 32 can be rotatably connected to the rotating body 31, and the above-mentioned first display component 10 and the second display component 20 can include a liquid crystal display screen and an assembly bracket installed on the liquid crystal display screen, and the above-mentioned first slide groove 11 can be set on the assembly bracket. The second display component 20 can be opened or retracted relative to the first display component 10 during the sliding process of the rotating connecting body 30 in the first slide groove 11. When the second display component 20 is opened relative to the first display component 10, the second display component 20 can be used for screen splicing with the first display component 10; when the second display component 20 is retracted relative to the first display component 10, the second display component 20 and the first display component 10 are attached to each other to form a single screen for use. Specifically, the overall screen formed by the splicing of the second display component 20 and the first display component 10 can be a top-down structure or a left-right structure. The following embodiments will be based on the second display component 20 being located below the first display component 10 when it is unfolded relative to the first display component 10, forming a spliced ​​screen of the top-down structure (the specific display effect is as follows Figure 4 shown).

[0037] In this embodiment, the shape of the first chute 11 is adapted to the rotating body 31, and the rotating body 31 can be located in the first chute 11 and will not fall off radially from the first chute 11. The rotating body 31 can slide or roll freely along the axial direction of the rotating shaft 32 in the first chute 11. For example, the cross section of the first chute 11 can be roughly U-shaped, including two parallel surfaces arranged oppositely and an arc surface connecting the two parallel surfaces, wherein the distance between the parallel surfaces is smaller than the outer diameter of the rotating body 31, and the diameter of the arc surface is slightly larger than the outer diameter of the rotating body, so that the rotating body 31 can be accommodated in the first chute 11 without leaving the chute.

[0038] It is understandable that the position of the first slide groove 11 can be set according to actual needs, for example, it can be set on the side of the first display component 10, or it can be set on the back of the first display component 10, and no further limitation is made here. Similarly, the above-mentioned shaft 32 can be fixed on the back of the second display component 20, or it can be fixed on the side. When using a single screen, the control rotating body 31 can be located at one end of the first slide groove 11 so that the second display component 20 shrinks relative to the first display component 10; when the screen needs to be spliced, an external force can be applied to push the rotating body 31 from one end of the first slide groove 11 to the other end, so that the second display component 20 is unfolded relative to the first display component 10. At this time, if the screen of the second display component 20 is set back to the screen of the first display component 10, the second display component 20 can be rotated so that the screen of the first display component 10 and the screen of the second display component 20 are located on the same screen, so that dual-screen splicing display can be performed.

[0039] In the embodiment of the present invention, by providing a first sliding groove 11 on the first display component 10, a rotating shaft 32 is fixed to the second display component 20, and a rotating body 31 fixedly connected to the rotating shaft 32 is located in the first sliding groove 11 and can slide along the first sliding groove 11, so that the second display component 20 can be in a state of contracting and expanding relative to the first display component 10. In the embodiment of the present invention, it is not necessary to separate the dual screens, and the single-screen and dual-screen switching can be performed by sliding. Therefore, the present invention improves the flexibility of dual-screen switching.

[0040] Optionally, the above-mentioned first sliding groove 11 is located on the back surface of the first display component 10, the rotating shaft 32 is located on the back surface of the second display component 20, and the rotating connection body 30 can slide between the first end and the second end of the first sliding groove 11. When the rotating connection body 30 is located at the first end of the first sliding groove 11, the back surface of the first display component 10 is attached to the back surface of the second display component 20; when the rotating connection body 30 is located at the second end of the first sliding groove 11, the second display component 20 can rotate relative to the first display component 10, and after rotation, the front surfaces of the first display component 10 and the second display component 20 are located on the same plane.

[0041] In this embodiment, the above-mentioned first display component 10 can have the same size as the second display component 20. When the rotating connection body 30 is located at the first end of the first sliding groove 11, the second display component 20 is in a contracted state relative to the first display component 10, and at this time, the second display component 20 will be hidden behind the first display component 10. When the rotating connection body 30 is located at the second end of the first sliding groove 11, the second display component 20 is in an expanded state relative to the first display component 10. Since the second display component 20 is located below the first display component, at this time, the upper end face of the second display component 20 is basically flush with the lower end face of the first display component 10, and the second display component 20 can be rotated so that the lower end face of the second display component 20 is attached to the upper end face of the first display component 10, thereby achieving the effect of seamless splicing.

[0042] Further, please refer to Figure 5 and Figure 6 simultaneously. In order to enable the second display component 20 to be attached to the first display component 10 after contracting relative to the first display component 10, in this embodiment, a column 12 protrudes from the first display component 10, and the first sliding groove 11 is provided on the column 12; a second sliding groove 21 for receiving the column 12 is provided at a position corresponding to the column 12 on the back surface of the second display component 20, and a fixing rod 211 extends outward from the inner wall of the second sliding groove 21, and a fixing hole 2111 adapted to the rotating shaft 32 is provided on the fixing rod 211.

[0043] In this embodiment, one end of the above-mentioned rotating shaft 32 is located within the fixing hole 2111, and it can be set to be axially rotatably connected or fixedly connected, but it cannot move axially. For example, it can be connected through a bearing, and no further limitation is made here. The above-mentioned fixing rod 211 can be perpendicular to the axial direction of the rotating shaft 32 or can be set to be inclined, but the central axis of the fixing hole 2111 coincides with the central axis of the rotating shaft.

[0044] Specifically, when the above-mentioned second chute 21 is just used to accommodate the above-mentioned column 12, the back surface of the second display component 20 and the back surface of the first display component 10 can be mutually attached.

[0045] Furthermore, please refer to Figures 1 to 8 simultaneously. An installation groove 22 is further provided on the back surface of the above-mentioned second display component 20. Oppositely arranged rotating shafts 23 are provided on two opposite side walls of the installation groove 22. The display terminal further includes a bracket 40 that can be accommodated in the installation groove 22. The bracket 40 is provided with installation holes 41 corresponding to the positions of the two rotating shafts 23 and is rotatably connected to the second display component 20 through the cooperation of the installation holes 41 and the rotating shafts 23.

[0046] For example, two oppositely arranged rotating shafts 23 can be provided at both ends of the top of the installation groove 22, where the top of the installation groove 22 is the end of the second display component 20 close to the first display component 10 when the second display component 20 is unfolded relative to the first display component 10.

[0047] In this embodiment, the bracket 40 is suspended on the rotating shaft 23 through the cooperation of the installation holes 41 and the rotating shafts 23. A specific curve can be provided in the installation holes 41 to make a tentative dead stop at the angle to be opened, ensuring the fixation of the opened bracket 40. At the same time, auxiliary feet can be provided at the end of the bracket 40 far from the installation holes 41 to increase the contact area, so that the display terminal can be placed on a fixed table. Specifically, when the bracket 40 is not needed, the bracket 40 can be integrally accommodated in the installation groove 22, so that the back surface of the second display component 20 can be attached to the back surface of the first display component 10. In addition, in this embodiment, two brackets 40 can be provided, and the two brackets 40 can be respectively located on both sides of the above-mentioned second chute 21.

[0048] Furthermore, the above-mentioned first display component 10 is further provided with a first groove 13 and a second groove 14 that are mutually displaced. The first groove 13 and the second groove 14 are mutually communicated. An avoidance groove 15 is provided between the first groove 13 and the first chute 11 to communicate the first groove 13 and the first chute 11. A contact 141 is provided in the second groove 14; the display terminal further includes a connecting shaft 50, a connecting piece 60, an elastic member 70, and a detection module (not shown in the figure). Among them,

[0049] The connecting shaft 50 is arranged in the first groove 13 and fixedly connected to the first display component 10;

[0050] The connecting piece 60 is connected to the elastic member 70 and can move axially along the connecting shaft 50 under the elastic contraction of the elastic member 70 and can contact the contact 141;

[0051] The detection module is electrically connected to the contact 141, and when it detects that the connecting piece 60 contacts the contact 141, it outputs a control signal to control the power-on / off of the display terminal and / or light up the display screen.

[0052] Optionally, the connecting piece 60 includes a connecting body 6621 sleeved on the connecting shaft 50, a first extending end 62 and a second extending end 63 extending from the connecting body 61. Among them, the connecting body 61 is connected to the elastic member 70 and can move axially along the connecting shaft 50 between a first position and a second position under the elastic contraction of the elastic member 70. When the connecting body 61 is in the first position, the first extending end 62 is partially located in the avoiding groove 15 and extends towards the first sliding groove 11, and the first extending end 62 cooperates with the rotating body 31 to control the movement of the connecting body 61 between the first position and the second position; when the connecting body 61 is in the second position, the second extending end 63 abuts against the contact 141;

[0053] In this embodiment, when the detection module detects that the second extending end 63 contacts the contact 141, it outputs a control signal to control the power-on / off of the display terminal and / or light up the display screen.

[0054] The above contact 141 can be a metal contact or other touch switches; the above second extending end 63 can be a sheet metal part or a structure for controlling the change of the connection state of the touch switch. For example, in this embodiment, preferably, the above contact 141 is two metal contacts, and the above second extending end 63 is a metal sheet. When the connecting body 61 is in the second position, the second extending end 63 contacts the two metal contacts to control the electrical connection of the two metal contacts, and the detection module can detect the connection state of the two metal contacts to determine whether the second extending end 63 contacts the contact 141.

[0055] Further, the elastic member 70 is a spring. The spring is sleeved on the connecting shaft, and one end of the spring abuts against the end of the first groove 13 away from the avoidance groove 15, and the other end abuts against the connecting body 61. One end of the connecting shaft 50 close to the avoidance groove 15 extends into the avoidance groove 15 to form a limiting plate 51. The limiting plate 51 and the spring cooperate to limit the movement of the connecting body 61 between the first position and the second position.

[0056] Specifically, in this embodiment, when the rotating connecting body 30 is located at the first end of the first chute 11, the connecting body 61 is in the second position, and the first protruding end 62 is located below the rotating body 31 and forms a clamping state. When the user presses the rotating shaft 32 or slides the second display component 20 relative to the first display component, causing the rotating connecting body 30 to slide towards the second end of the first chute 11, the rotating body 31 will squeeze the first protruding end 62, causing the spring to contract, and the connecting body 61 will move from the second position to the first position. When the first protruding end 62 abuts against the peripheral wall of the rotating body 31, the spring is compressed to the shortest. At this time, the connecting body 61 is located at the first position, and the second protruding end 63 will abut against the contact point 141. When the rotating connecting body 30 continues to slide towards the second end of the first chute 11, under the elastic restoring force of the spring, the connecting body 61 will return from the first position to the second position, and the first protruding end 62 is located above the rotating body 31. When the rotating connecting body 30 slides towards the first end of the first chute 11, under the elastic restoring force of the spring, the connecting body 61 will return from the first position to the second position, and the first protruding end 62 is located below the rotating body 31.

[0057] It should be noted that the elastic member 70 can be set as other elastic members such as sponge and elastic sheet in addition to being set as a spring. In addition, the spring can be arranged in other ways in addition to the above-mentioned arrangement. For example, multiple springs can be arranged around the connecting shaft 50 instead of being sleeved on the connecting shaft 50. At the same time, the spring can also be arranged between the limiting plate 51 and the connecting body 61, etc. These methods can all achieve the purpose, and will not be listed one by one here.

[0058] Further, a limiting groove 52 is axially recessed on the outer periphery of the connecting shaft 50, and a limiting protrusion 611 adapted to the limiting groove 52 is provided at the position of the connecting body 61 corresponding to the limiting groove 52.

[0059] In this embodiment, the above-mentioned limiting bump 611 is arranged in the limiting groove 52. Specifically, the above-mentioned connecting shaft 50 is a cylinder, and a round hole adapted to the connecting shaft 50 is provided on the connecting body 61, and a limiting bump 611 protrudes from the inner wall of the round hole. Since the limiting bump 611 is arranged on the connecting body 61, the connecting body 61 can be effectively prevented from rotating relative to the connecting shaft 50, and further, it is avoided that the second protruding end 63 cannot normally contact the contact 141 due to the rotation of the connecting body 61. Therefore, the reliability of the contact between the second protruding end 63 and the contact 141 is improved in the present invention.

[0060] Furthermore, in order to improve the sliding stability of the rotating body 31 in the first sliding groove 11, in this embodiment, a ball (not shown in the figure) is provided on the peripheral wall of the rotating body 31, and the ball contacts the inner wall of the first sliding groove 11. In this embodiment, the above-mentioned balls can be multiple and are arranged on the same circumference. Specifically, the multiple balls abut against the inner wall of the first sliding groove 11 and can roll freely, so as to realize the sliding or rolling of the rotating body 31 in the first sliding groove 11.

[0061] Furthermore, a metal elastic sheet 311 is provided on the rotating body 31, and a metal connecting elastic sheet 111 is provided in the first sliding groove 11. When the rotating body 31 slides to the second display component 20 is unfolded relative to the first display component 10, the metal elastic sheet 311 abuts against the metal connecting elastic sheet 111; the display terminal further includes a control module (not shown in the figure). When the control module detects that the metal elastic sheet 311 abuts against the metal connecting elastic sheet 111, it controls the first display component 10 and the second display component 20 to be in a screen splicing display state.

[0062] In this embodiment, the above-mentioned control module can be a control unit inside the first display component 10. An internal split-screen software and a CPU are also provided in the first display component 10. When the metal elastic sheet 311 does not abut against the metal connecting elastic sheet 111, the control unit outputs a "single signal" to the CPU, and the CPU controls the internal split-screen software to make the picture display only on the first display component 10, that is, to show a single-screen mode (non-dual-screen working state); when the metal elastic sheet 311 abuts against the metal connecting elastic sheet 111, the control unit outputs a "dual signal" to the CPU, and the CPU controls the internal split-screen software to convert the display signal of the first display component 10 into two signals and output them to the first display component 10 and the second display component 20 respectively for screen splicing display, so that the first display component 10 and the second display component 20 form a large-screen display effect (i.e., dual-screen working mode).

[0063] It can be understood that in the dual-screen working mode, it may not be screen splicing display, and two independent pictures can also be displayed. Here, only the state of the screen display is controlled.

[0064] Since in the embodiments of the present invention, the screen can also be automatically controlled to perform screen splicing display by detecting whether the metal elastic sheet 311 is in contact with the metal connecting elastic sheet 111, thus eliminating the need for the user to actively switch, the flexibility of screen splicing display can be further improved.

[0065] Optionally, please also refer to Figures 9 to 12 , both ends of the first sliding groove 11 are provided with a first limiting step 112 and a second limiting step 113 for restricting the rotation body 31 from sliding out.

[0066] In this embodiment, the above-mentioned limiting steps can also be replaced by other structures such as limiting bumps, as long as it can ensure that the rotation body 31 axially disengages from the first sliding groove. For example, the inner diameters of both ends of the first sliding groove 11 can be gradually reduced to show the rotation body 31 sliding out. In addition, structures such as plastic plugs can be added, which will not be listed one by one here.

[0067] Optionally, both the first limiting step 112 and the second limiting step 113 are provided with avoidance holes for the rotation shaft 32 to pass through.

[0068] In this embodiment, the first limiting step 112 is located at the first end of the first sliding groove 11, and the second limiting step 113 is located at the second end of the first sliding groove 11. When the rotation body 31 is located at the first end of the first sliding groove 11, the end of the rotation shaft 32 that is not connected to the fixing hole 2111 passes through the avoidance hole to form an operation button. Thus, it can be used for the user to perform button operations to achieve one-key power-on. Specifically, when the user presses the operation button, the contact time between the second protruding end 63 and the contact point 141 can be controlled, and the power-on and off of the display terminal or the display state of the screen can be controlled according to the contact time. For example, when the terminal is in the power-off or black screen state, if the second protruding end 63 contacts the contact point 141, the power-on or screen lighting can be controlled. In addition, when the terminal is in the power-on state, if the contact time between the second protruding end 63 and the contact point 141 reaches the preset time, the display terminal is controlled to power off.

[0069] Further, the metal connecting elastic sheet 111 is a charging contact or an audio transmission contact. In this embodiment, a charging contact or an audio transmission contact is used as the metal connecting elastic sheet 111, so that when the second display component 20 contracts relative to the first display component 10, a headphone jack or a charging hole is formed by the avoidance hole on the second limiting step 113.

[0070] Further, the above-mentioned metal connecting elastic piece 111 can also be a display signal transmission contact. Specifically, the above-mentioned metal elastic piece 311 can be electrically connected to the display signal transmission end of the second display component. Based on the mutual connection between the metal connecting elastic piece 111 and the metal elastic piece 311, the transmission of the display signals of both can be realized, thereby achieving the purpose of screen splicing. In addition, in other embodiments, the contacts for performing display signal transmission can also be arranged at other positions. For example, they can be arranged at the part where the second display component 20 is in contact with the first display component 10 when the second display component 20 is opened relative to the first display component 10. At the same time, other signal transmission methods can also be set, such as using wireless to transmit signals.

[0071] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
