[0051] The following detailed description will further illustrate the present application in conjunction with the above-mentioned figures. DETAILED DESCRIPTION

[0052] The display mechanism of the embodiments of the present application can be integrally arranged on any device requiring image display, as a functional module for displaying images. For example, the display mechanism can be used as an image display functional module of smart home, various processing equipment, detection equipment (such as a sequencer), etc. In at least one embodiment of the present application, the display mechanism can also support human-computer interaction, for example, can receive user touch, sliding, gesture, etc. operation modes.

[0053] Please refer to Figure 1 and Figure 2 , the display mechanism 1 of the embodiments of the present application includes a mounting frame 10, a display 20, a first rotary shaft structure 30, a second rotary shaft structure 40, and a shielding frame 50. The display 20 is rotatably connected to the mounting frame 10 through the first rotary shaft structure 30 and the second rotary shaft structure 40, and the shielding frame 50 is fixedly connected to the mounting frame 10.

[0054] The mounting frame 10 is used to fixedly mount the display 20 and the shielding frame 50. When the display mechanism 1 is applied to other devices, it is fixedly connected to the related components (such as the shell) of the device through the mounting frame 10. The mounting frame 10 is in the form of a thin plate as a whole, and a mounting opening 13 is formed in the center. The display 20 is located in the mounting opening 13. The first rotary shaft structure 30 is connected to the mounting frame 10 and the display 20 respectively, and the second rotary shaft structure 40 is also connected to the mounting frame 10 and the display 20 respectively, and both the first rotary shaft structure 30 and the second rotary shaft structure 40 are located at the mounting opening 13. By arranging the first rotary shaft structure 30 and the second rotary shaft structure 40, the display 20 can rotate in the first direction and the second direction (see Figure 5 and Figure 6 , the dashed curve arrows represent the rotation direction, Figure 5 and Figure 6 , the shielding frame 50 is hidden), the first direction and the second direction are two opposite directions. The shielding frame 50 is fixedly connected to the mounting frame 10 and surrounds the periphery of the display 20.

[0055] The mounting frame 10 has a first surface 11 and a second surface 12 arranged oppositely. A mounting opening 13 penetrates the first surface 11 and the second surface 12. The display 20 has a display surface 21 and a mounting surface 22 arranged oppositely. The display surface 21 is a surface for displaying images (and implementing human-computer interaction). The first pivot structure 30 and the second pivot structure 40 are connected to the first surface 11 and the mounting surface 22. The shielding frame 50 is fixedly connected to the first surface 11, and the shielding frame 50 surrounds the edge connected to the mounting opening 13.

[0056] There is a spacing region between the display 20 and the mounting frame 10 to reserve space for the rotation of the display 20 relative to the mounting frame 10. The orthogonal projection of the shielding frame 50 on the mounting frame 10 completely covers the spacing region. When the display 20 is in a 0° rotation state, the first surface 11, the second surface 12, the display surface 21, and the mounting surface 22 are parallel to each other. When the display 20 is in a state of rotation greater than 0°, the spacing region between the display 20 and the mounting frame 10 increases. By arranging the shielding frame 50, it is beneficial to block dust and the like from entering the device housing to which the display mechanism 1 is applied from the spacing region. The shielding frame 50 includes a light shielding material, which is beneficial to avoid external light from entering the spacing region to interfere with the operation of the optical path structure when the display mechanism 1 is applied to a device (such as a sequencer) including the optical path structure, and is beneficial to avoid light leakage of the device itself through the spacing region.

[0057] Since the display 20 can rotate relative to the mounting frame 10, the shielding frame 50 extends a certain height in a direction perpendicular to the mounting frame 10 to reserve rotation space for the display 20 and avoid blocking the rotation of the display 20. In at least one embodiment of the present application, the specific height of the shielding frame 50 can also be used to limit the maximum rotation angle of the display 20 relative to the mounting frame 10: the display 20 cannot continue to rotate after contacting the shielding frame 50.

[0058] In the present embodiment, the mounting frame 10 and the display 20 both have a rectangular planar profile. The shape of the mounting opening 13 is adapted to the planar profile of the display 20 and is also rectangular and slightly larger than the planar profile of the display 20. The planar profile of the shielding frame 50 is adapted to the shape of the mounting opening 13 and is also rectangular and slightly larger than the planar profile of the display 20. The shielding frame 50 is also provided with an opening 51, and part of the display 20 is exposed relative to the opening 51. The display 20 is provided with a plurality of communication interfaces 23. During the operation of the display mechanism 1, the communication interfaces need to be connected to other structures by wire insertion. The opening 51 is reserved for facilitating wire insertion.

[0059] The shielding frame 50 has a first side 52, a second side 53, a third side 54 and a fourth side 55, wherein the first side 52, the third side 54, the second side 53 and the fourth side 55 are connected in sequence. The first rotation shaft structure 30 is located at the third side 54, and the second rotation shaft structure 40 is located at the fourth side 55. The first side 52, the third side 54 and the fourth side 55 have substantially the same width, and the width of the second side 53 is greater than the width of the first side 52, the third side 54 and the fourth side 55. The first side 52 is arranged to be narrow, which is conducive to further facilitating wire insertion. The third side 54 and the fourth side 55 are arranged to be narrow, which is conducive to mounting the first rotation shaft structure 30 and the second rotation shaft structure 40 (the third side 54 and the fourth side 55 are respectively provided with a gap slot for avoiding the locking screw of the first rotation shaft structure 30 and the second rotation shaft structure 40). The second side 53 is arranged to be wide, which is conducive to improving the shielding effect of dust and light.

[0060] The first rotation shaft structure 30 and the second rotation shaft structure 40 are symmetrically distributed at two opposite sides of the display 20. The first rotation shaft structure 30 and the second rotation shaft structure 40 rotate around the rotation shaft L when the display 20 rotates. The rotation shaft L coincides with the center line of the display 20, which is conducive to balancing the weight of the display 20 on both sides of the rotation shaft L. In other embodiments of the present application, the position of the rotation shaft L can also be parallel to but not coinciding with the center line of the display 20. In other embodiments of the present application, the display mechanism 1 can only include one of the first rotation shaft structure 30 and the second rotation shaft structure 40 to realize rotation.

[0061] The first rotation shaft structure 30 and the second rotation shaft structure 40 have substantially the same structure and function. The following takes the first rotation shaft structure 30 as an example for illustration.

[0062] Please refer to Figure 3 and Figure 4 , the first rotation shaft structure 30 includes a first connecting component 31 and a second connecting component 32. The first connecting component 31 is connected to the mounting frame 10, the first connecting component 31 is connected to the display 20, and the first connecting component 31 and the second connecting component 32 are located at the mounting opening 13. The first connecting component 31 and the second connecting component 32 are rotationally connected, and the second connecting component 32 can rotate in the first direction and the second direction around the rotation shaft L relative to the first connecting component 31. When the second connecting component 32 rotates relative to the first connecting component 31, it synchronously drives the display 20 to rotate relative to the mounting frame 10.

[0063] The first connecting assembly 31 comprises a first connecting block 311 fixedly connected with the mounting frame 10 and a first rotating piece 312. The second connecting assembly 32 comprises a second connecting block 321 fixedly connected with the display 20 and a second rotating piece 322. One of the first rotating piece 312 and the second rotating piece 322 is provided with an axle hole, and the other is provided with an axle shaft which is located in the axle hole and can rotate in the axle hole.

[0064] In a direction perpendicular to the axle shaft L, there is a gap d between the first connecting block 311 and the second connecting block 321. The gap d is used to reserve the rotating space of the second connecting block 321 during rotation. When the display 20 is in the 0° state, the gap d between the first connecting block 311 and the second connecting block 321 is the widest. During the process of gradually increasing the rotation angle of the display 20, the gap d gradually decreases until the second connecting block 321 abuts against the first connecting block 311, that is, the gap is reduced to 0, and the display 20 cannot continue to rotate. Therefore, by setting the distance value of the gap between the first connecting block 311 and the second connecting block 321, the maximum rotation angle that the display 20 can reach can be set.

[0065] The display 20 can be an organic light-emitting diode display, a micro light-emitting diode display, a liquid crystal display, etc., which can include an array substrate, a light-emitting element, a liquid crystal cell, a backlight module, etc., and thus has a relatively large weight. By setting the damping of the first axle shaft structure 30 and the second axle shaft structure 40, when the display 20 is stopped during rotation, the display 20 can be kept at the angle state at the moment when the display 20 is stopped, which is beneficial to avoid the change or even the return to the 0° state of the display 20 under the action of gravity.

[0066] The first axle shaft structure 30 further comprises a gasket 33 fixedly connected to the mounting frame 10, and the first rotating piece 312 and the second rotating piece 322 are in direct contact with the gasket 33. The gasket 33 is located at the bottom of the first rotating piece 312 and the second rotating piece 322 to support the first rotating piece 312 and the second rotating piece 322. Since the display 20 has a relatively large weight, the first rotating piece 312 and the second rotating piece 322 bear a relatively large torsion in opposite directions during the rotation of the display 20. By setting the gasket 33, it is beneficial to avoid the deformation or even the breakage of the first rotating piece 312 and the second rotating piece 322 during the rotation. In addition, the gasket 33 is made of polyether ketone (PEK) material, which can play a lubricating role when the first rotating piece 312 and the second rotating piece 322 rotate, and is also beneficial to avoid the deformation or even the breakage of the first rotating piece 312 and the second rotating piece 322 during the rotation.

[0067] The surface of the gasket 33 in contact with the first rotating member 312 and the second rotating member 322 is a plane. In other embodiments of the present application, the surface of the gasket 33 in contact with the first rotating member 312 and the second rotating member 322 is adapted to the surface of the first rotating member 312 and the second rotating member 322. For example, in the present embodiment, the side of the first rotating member 312 and the second rotating member 322 facing the gasket 33 is a curved surface, and the surface of the gasket 33 in contact with the first rotating member 312 and the second rotating member 322 can also be a concave surface to better support the first rotating member 312 and the second rotating member 322. In the present embodiment, a recess 111 is also formed on the first surface 11 of the mounting frame 10. The first rotating member 312, the second rotating member 322 and the gasket 33 are all located in the recess 111. The first connecting block 311 and the second connecting block 321 cover the recess 111. In this way, after the first connecting block 311 and the second connecting block 321 are mounted, the overall thickness of the display mechanism 10 in the direction perpendicular to the mounting frame 10 is smaller.

[0068] When the display mechanism 10 is applied to other devices, the side of the display 20 where the communication interface 23 is formed faces downward, i.e., toward the working plane such as the ground or a table. Figure 5 As shown, when the upper part of the display 20 is pushed, the display 20 rotates in the first direction, Figure 6 As shown, when the lower part of the display 20 is pushed, the display 20 rotates in the second direction. The display 20 has a rotation freedom of 10° in the first direction and the second direction, respectively.

[0069] Please refer to Figure 7 The sequencing instrument 100 provided by the embodiments of the present application includes a device housing 2, an optical mechanism 3 and the above-mentioned display mechanism 1. The display mechanism 1 is embedded in the device housing 2. The optical mechanism 3 is located in the device housing 2. The optical mechanism 3 is used to realize optical detection, for example, to detect the genetic sequence of a biological sample. During the operation of the optical mechanism 3, there can be laser light, fluorescence and the like in the optical path. The image displayed by the display mechanism 1 can include information associated with the overall machine state (including the optical structure 3). For example, the display mechanism 1 is used to display the genetic sequencing progress, the reagent remaining amount, the internal and external temperatures and the like. When the display mechanism 1 has a human-computer interaction function, the user can input operation instructions to control the work progress.

[0070] The overall size of the sequencing instrument 100 is large, and it is usually placed on the ground. The height of the display mechanism 1 is generally consistent with the parallel line of sight height of the user. Due to the height difference of different users, the display mechanism 1 of the present application is rotatable by setting the display 20, so that the user can flexibly adjust the pitch angle of the display 20, and it is convenient for users of different heights to watch the image displayed by the display 20 or operate on the display 20. When the display 20 is in the 0° state, the display surface 21 is perpendicular to the ground. And the adjustment mode of the display 20 of the embodiments of the present application is that the user gently pushes the display 20 with the fingers Figure 5and Figure 6 The dashed straight arrow in the figure represents the position of the finger pushing the display 20, and the display 20 can be pushed without the need of complex motor driving, which is beneficial to reduce the operation difficulty and simplify the mechanical structure.

[0071] Those skilled in the art should understand that the above embodiments are only used to illustrate but not to limit the present application, and any modification and change made to the above embodiments within the spirit and principle of the present application shall fall into the scope of protection of the present application.
