Through the docking of the guiding block 41 and the guiding block docking hole 18, the sliding direction of the display base 1 in the slide rail 3 is further aligned, facilitating the precise alignment between the Type-C interface plug 5 and the Type-C interface socket 9 and ensuring the communication docking accuracy.

[0036] The hole edge line of the guiding block docking hole 18 is a chamfered structure, forming a guiding hole inclined surface 17, corresponding to the guiding inclined surface 42 at the end of the guiding block 41, which can improve the guiding effect.

[0037] A locking mechanism is also provided in the display base 1. The locking mechanism includes a positioning pin 83. The positioning pin 83 is elastically led out from the bottom surface of the display base 1. A pin hole 31 is provided on the lower rail edge 33 corresponding to the bottom surface of the slide rail 3 and the coordination rail. The setting position of the positioning pin 83 is positionally matched with the setting position of the pin hole 31, so that when the second communication docking structure on the end face of the first end of the display base 1 is positionally connected to the first communication docking structure 4, the positioning pin 83 can be elastically embedded into the pin hole 31 to achieve locking.

[0038] In this embodiment, the pin hole 31 is provided at the first end position of the slide rail 3, and the first communication docking structure 4 is arranged at the second end position of the slide rail, which can reduce the contact section length between the positioning pin 83 and the lower rail edge 33 and reduce wear.

[0039] The locking mechanism further includes a button 82. The button 82 is elastically led out from the bottom surface of the display base 1 and is located outside the coordination rail. The button 82 is fixedly connected to the positioning pin 83, so that by pressing the button 82 conveniently, the locking state of the positioning pin 83 limited in the slide rail 3 can be controlled by external pressing of the button 82.

[0040] To achieve the elastic arrangement of the locking mechanism, in this embodiment, a fixed stop block 6 is provided inside the display base 1. The fixed stop block 6 is positionally aligned with the button 82 up and down, and a compression spring 7 is connected between the fixed stop block 6 and the button 82. The size of the button 82 is larger than that of the positioning pin 83, which is convenient for installing the compression spring 7.

[0041] In order to ensure the effectiveness of the compression spring 7, in this embodiment, the fixed block 6 and the button 82 are respectively provided with a first spring guide hole 61 and a second spring guide hole 81 that match each other. The compression spring 7 is arranged in the two spring guide holes, which can ensure the vertical posture stability of the compression spring 7 and the axial pressing performance of the button 82.

[0042] The locating pin 83 and the button 82 are connected by a connecting rod. The lower end surface of the main body housing 1 is provided with a locating pin lead-out hole 12 and a button lead-out hole 11 corresponding to the locating pin 83 and the button 82, respectively. The locating pin lead-out hole 12 and the button lead-out hole 11 are spaced apart. The main body housing 1 therebetween can block the extension of the connecting rod, thereby limiting the extension length of the locating pin 83 and the button 82 through the connecting rod, ensuring the pressing stroke. A guide rod 86 is also provided on the connecting rod. The guide rod 86 extends in the opposite direction to the locating pin 83 and is vertically arranged. A first protrusion 14 is also provided on the inner side wall of the display screen base 1 corresponding to the fixed block 6 to form a vertical guide groove 13. The guide rod 86 is disposed in the vertical guide groove 13 to improve the axial pressing of the locating pin 83 and the button 82.

[0043] In order to improve the guiding effect of the guide rod 86, in this embodiment, a second protrusion 62 is further provided on the side of the fixed stop block 6 corresponding to the first protrusion 14. The second protrusion 62 is matched with the first protrusion 14 so that the vertical guide groove 13 can be enclosed into a vertical guide hole.

[0044] In order to avoid excessive pressing, which may cause the positioning pin 83 and the button 82 to disengage from the corresponding lead-out hole, in this embodiment, a third protrusion 19 is further provided on the inner side wall corresponding to the display screen base 1 and the fixed stopper 6. The third protrusion 19 is provided at the top end of the vertical guide hole, which can limit the upward movement of the guide rod 86, thereby improving the pressing stroke limiting effect of the locking structure, and the fixed stopper 6 is screwed and fixedly connected to the third protrusion 19. The size of the third protrusion 19 is sufficient and can be reused to fix the fixed stopper 6, thereby ensuring the fixing effect of the fixed stopper 6.

[0045] In order to improve the removal effect of the display screen base 1, in this embodiment, the end edge line of the positioning pin 83 is a chamfered structure, forming a positioning pin bevel 85, which can reduce the edge alignment requirement with the pin hole 31, facilitate the conversion between the force in the sliding direction and the force in the vertical direction, guide the movement of the positioning pin 83, and make the insertion and withdrawal of the positioning pin 83 to the pin hole 31 smoother.

[0046] To further improve the smoothness of the insertion and withdrawal of the positioning pin 83 into the pin hole 31, in this embodiment, the end face of the positioning pin 83 is a two-way inclined plane, forming a linear top 85, and the direction of the inclined plane is consistent with the extension direction of the coordination rail, so that the end line of the linear top 85 is perpendicular to the sliding direction and is in surface contact with the rail surface of the lower rail edge 33. The setting of the inclined plane can reduce the pressing stroke requirement for the positioning pin 83 to enter the slide rail 3 and ensure the convenience of using the locking mechanism.

[0047] To facilitate the sliding-in of the display screen base 1, the end face of the first end of the slide rail 3 is also provided with an inclined plane structure to form a guiding end face 34, which can reduce the alignment accuracy requirement for the display screen base 1 to slide into the slide rail 3 and improve the operation convenience.

[0048] Among them, the installation edge corresponding to the installation of the main body housing 2 and the display screen base 1 is a groove structure. The length of this groove structure is greater than the length of the slide rail 3, and one end is open. The redundant part at the open end can be synchronously used for the sliding-in guiding of the display screen base 1, and the end face of the other end can be used for the installation of the first communication docking structure 4.

[0049] Other parts in the display screen base 1 are used for the docking of the display screen. Due to the detachable design, in addition to the rotatable connection for easy flipping, the docking between the display screen and the display screen base 1 can also adopt a fixed connection method. The specific configuration method between the display screen and the display screen base 1 can be specifically selected according to specific requirements, and this application does not make special limitations on this.

[0050] Taking disassembly as an example, during use, pressing the button 82 can drive the positioning pin 83 to move upward. Under the cooperation of the guide rod 86 and the vertical guide groove 13, no abnormal phenomena such as key jamming will occur during the movement of the locking mechanism. When the button 82 is pressed to the bottom, the positioning pin 83 completely disengages from the pin hole 31, and the display screen base 1 is no longer subject to resistance in the horizontal direction, so that the display screen base 1 can be completely pulled out from the slide rail 3, thus completing the disassembly of the display screen base 1.

[0051] The display screen quick-release device and the terminal device provided by the present utility model can effectively realize the disassembly and assembly of the second display screen, providing convenience for the mechanical switching of the dual-screen display tablet between the single-screen display mode and the dual-screen display mode, effectively taking into account the high mobility of the single-screen display mode and the high processing power of the dual-screen display mode, and improving the comprehensive performance of the device.
