[0050] The locking structure and display device provided in the embodiments of the present application are now described.

[0051] See also Figures 1 to 4 ,as well as Figure 7 and Figure 8 As shown, the locking structure provided by the embodiment of the present application at least includes a rotating member 10, and the rotating member 10 has a first part 101 and a second part 102 connected coaxially. The first part 101 is provided for connecting the first locking object and is configured to be able to rotate relative to the first locking object. The peripheral wall of the second part 102 is provided with a locking portion 1021 and an unlocking portion 1022, and the locking portion 1021 and the unlocking portion 1022 are spaced apart in both the circumferential direction and the axial direction. The rotating member 10 is configured such that when the locking portion 1021 is rotated in the first direction, it presses on the second locking object and locks the first locking object and the second locking object. The rotating member 10 is also configured such that when the locking portion 1021 is rotated in the second direction, it disengages from the second locking object and the unlocking portion 1022 drives away from the second locking object to unlock; wherein, the first direction and the second direction are opposite.

[0052] In some embodiments, the rotating member 10 is an integrally formed component, that is, the first portion 101 and the second portion 102 are integrally formed, and the locking portion 1021 and the unlocking portion 1022 are integrally formed on the second portion 102. The radial dimensions of the first portion 101 and the second portion 102 may be the same or different. In this embodiment, optionally, the radial dimensions of the first portion 101 and the second portion 102 are different, and the radial dimension of the first portion 101 is greater than the radial dimension of the second portion 102.

[0053] The locking structure provided by the embodiment of the present application, wherein the rotating member 10 has a first part 101 and a second part 102 connected coaxially. The first part 101 can be connected to a first locking object and can rotate relative to the first locking object, and the locking structure can be positioned on the first locking object through the first part 101. The peripheral wall of the second part 102 is provided with a locking portion 1021 and an unlocking portion 1022, and the locking portion 1021 and the unlocking portion 1022 are spaced apart in both the circumferential direction and the axial direction, and the first part 101 can rotate synchronously with the second part 102 relative to the first locking object.

[0054] When the rotating member 10 rotates in the first direction, the locking portion 1021 of the second part 102 presses on the second locking object and locks the first locking object and the second locking object. When the rotating member 10 rotates in the second direction, the locking portion 1021 of the second part 102 disengages from the second locking object, and the first locking object and the second locking object are in a detachable state. The unlocking portion 1022 of the second part 102 rotates in the second direction synchronously, and the unlocking portion 1022 drives away from the second locking object, thereby unlocking the first locking object and the second locking object.

[0055] The locking structure provided in the embodiment of the present application is applied to the locking and unlocking between the display component 100 and the fixed box 200. The locking structure can be selectively rotatably mounted on the display component 100. The locking structure can be rotated relative to the display component 100. The unlocking portion 1022 and the locking portion 1021 can lock or unlock the fixed box 200 and the display component 100 in different directions.

[0056] By adopting the locking structure provided in the embodiment of the present application, the locking part 1021 can be locked or the unlocking part 1022 can be unlocked by rotating in the opposite direction, and the locking degree between the display assembly 100 and the fixed box 200 can be adjusted according to the actual locking requirements without locking the two too tightly. In addition, the processing accuracy of the fixed box 200 does not need to be precisely controlled, and it is only necessary that the locking part 1021 can be smoothly pressed on the fixed box 200. Furthermore, the fixed box 200 can be smoothly driven away from the display assembly 100 through the unlocking part 1022, and the display assembly 100 and the fixed box 200 can be conveniently and quickly detached, and the processing cost of the fixed box 200 is reduced.

[0057] A polygonal hole 103 may be opened on the central axis of the rotating member 10, and the rotating member 10 may be driven to rotate by a polygonal wrench or other tools to achieve the unlocking or locking function.

[0058] In some embodiments, the unlocking portion 1022 is disposed between the locking portion 1021 and the first portion 101 , and the unlocking portion 1022 and the locking portion 1021 are disposed on opposite sides of a peripheral wall of the second portion 102 .

[0059] In this embodiment, the locking portion 1021 can be rotated 180° from the locking position along the second direction to a position as the starting position. At the starting position, the display assembly 100 and the fixed housing 200 have not been assembled, or the display assembly 100 and the fixed housing 200 are in a merged state, but are not locked to each other. The locking portion 1021 is rotated 180° along the first direction from the starting position to the locking position. At this time, the locking portion 1021 is pressed on the surface of the fixed housing 200 away from the display assembly 100, and the locking structure itself is rotationally connected to the display assembly 100. The circumferential position of the locking structure relative to the display assembly 100 and the fixed housing 200 can be changed, but the axial position of the locking structure relative to the display assembly 100 and the fixed housing 200 remains unchanged. Therefore, with the help of the circumferential rotation of the locking structure, the display component 100 and the fixed box 200 can be locked along the axial direction of the locking structure. The surfaces of the display component 100 and the fixed box 200 that face each other can be fitted together, or they can be fixed at a set distance without affecting the fixation of the relative position between the display component 100 and the fixed box 200.

[0060] When the locking portion 1021 is located at the starting position, the unlocking portion 1022 can be located exactly at the locking position. In the process of the locking portion 1021 rotating from the starting position to the locking position, the unlocking portion 1022 rotates 180° from the locking position along the first direction. When unlocking is required, the unlocking portion 1022 rotates 180° from this position along the second direction, applies force from the fixed housing 200 toward one side surface of the display assembly 100, and then drives the fixed housing 200 away from the display assembly 100 along the axial direction of the locking structure. In this way, the distance between the display assembly 100 and the fixed housing 200 along the axial direction of the locking structure is pulled apart, and the two can be easily separated and disassembled.

[0061] In some other embodiments, the angle between the unlocking portion 1022 and the locking portion 1021 along the circumference of the second portion 102 may be 90° or greater than 90°.

[0062] In this embodiment, the locking portion 1021 can be rotated 90° or more than 90° from the locking position along the second direction as the starting position. At the starting position, the display assembly 100 and the fixed housing 200 have not been assembled, or the display assembly 100 and the fixed housing 200 are in a merged state, but are not locked to each other. The locking portion 1021 is rotated 90° or more than 90° along the first direction, from the starting position to the locking position, at which time the locking portion 1021 is pressed on the surface of the fixed housing 200 away from the display assembly 100, and the locking structure itself is rotationally connected to the display assembly 100, the circumferential position of the locking structure relative to the display assembly 100 and the fixed housing 200 can be changed, but the axial position of the locking structure relative to the display assembly 100 and the fixed housing 200 remains unchanged. Therefore, with the help of the circumferential rotation of the locking structure, the display component 100 and the fixed box 200 can be locked along the axial direction of the locking structure. The surfaces of the display component 100 and the fixed box 200 that face each other can be fitted together, or they can be fixed at a set distance without affecting the fixation of the relative position between the display component 100 and the fixed box 200.

[0063] When the locking portion 1021 is located at the starting position, the unlocking portion 1022 can be located exactly at the locking position, or slightly deviated from the locking position along the second direction toward the starting position. In the process of the locking portion 1021 rotating from the starting position to the locking position, the unlocking portion 1022 rotates 90° along the first direction from the locking position, or rotates 90° along the first direction past the locking position. When unlocking is required, the unlocking portion 1022 rotates 90° along the second direction from this position, applies force from the fixed housing 200 toward one side surface of the display assembly 100, and then drives the fixed housing 200 away from the display assembly 100 along the axial direction of the locking structure. In this way, the distance between the display assembly 100 and the fixed housing 200 along the axial direction of the locking structure is pulled apart, and the two can be easily separated and disassembled.

[0064] Of course, in some other embodiments, the angle between the unlocking portion 1022 and the locking portion 1021 along the circumferential direction of the second portion 102 may be less than 90°.

[0065] In some embodiments, the locking portion 1021 is protruded on the peripheral wall of the second portion 102. By making the locking portion 1021 protrude radially from the second portion 102, when the locking structure is rotated, the peripheral wall of the second portion 102 can be spaced apart from the wall of the fixed box 200, or can be in flush contact with the wall of the fixed box 200, and the locking portion 1021 is pressed against the surface of the side of the fixed box 200 away from the display assembly 100.

[0066] In some embodiments, the surface of the locking portion 1021 that contacts the fixed box 200 may be an arc-shaped surface protruding toward the fixed box 200. When the locking portion 1021 enters the surface of the fixed box 200, the arc can provide a guiding effect to facilitate smooth entry into the surface of the fixed box 200.

[0067] In other embodiments, a positioning groove extending along the circumferential direction may also be provided on the peripheral wall of the second part 102. When the locking structure is rotated, the box body of the fixed box body 200 enters the positioning groove. The axial dimension of the positioning groove is greater than or equal to the thickness of the box wall of the fixed box body 200 to ensure that the box wall can enter the positioning groove. The two side walls of the positioning groove along the axial direction can position the fixed box body 200 so that it is locked relative to the display assembly 100. It should be noted that both sides of the positioning groove along the circumferential direction are open to ensure that the box wall can smoothly enter and slide out of the positioning groove during the rotation of the locking structure.

[0068] In some embodiments, the unlocking portion 1022 is protruded on the peripheral wall of the second portion 102 , the unlocking portion 1022 extends to have a length in the circumferential direction and to have a thickness in the axial direction, and the thickness of the unlocking portion 1022 gradually increases along the second direction.

[0069] During the rotation of the locking structure in the second direction, the unlocking part 1022 rotates in the second direction synchronously. The thinnest portion of the unlocking part 1022 is the tip portion, which first fits into the micro gap between the fixed box 200 and the display assembly 100. As the locking structure continues to rotate in the second direction, the unlocking part 1022 continuously enters between the fixed box 200 and the display assembly 100 from the tip portion. As more and more portions of the unlocking part 1022 enter, and the thickness of the unlocking part 1022 continues to increase, the wall of the fixed box 200 is driven away from the display assembly 100, and then the two are unlocked by the unlocking part 1022.

[0070] In some embodiments, the unlocking portion 1022 is arc-shaped, and the outer periphery of the unlocking portion 1022 is parallel to the peripheral wall of the second portion 102 .

[0071] The unlocking portion 1022 is set to be arc-shaped, and the extension path of the unlocking portion 1022 is consistent with the rotation path of the locking structure, so that the force applied by the unlocking portion 1022 is consistent with the rotation of the locking structure, ensuring the effectiveness and stability of the driving process.

[0072] In some embodiments, the locking structure further includes a fixing member 20, which is movably connected to the rotating member 10, and the first part 101 is configured to be connected to the first locking object through the fixing member 20, and the fixing member 20 is configured to allow the rotating member 10 to rotate along the first direction and the second direction.

[0073] The fixing member 20 can be connected to the first locking object in any form, that is, it can be connected to the display assembly 100 in any form, for example, it can be fastened to the display assembly 100 by a screw, it can be mounted on the display assembly 100 by setting a snap-fit ​​structure, or it can be fixed to the display assembly 100 by riveting or latching. In order to ensure good fixation of the fixing member 20 to the locking structure, the fixation between the fixing member 20 and the display assembly 100 is required to be relatively reliable.

[0074] In some embodiments, the first portion 101 protrudes radially from the second portion 102 to form a step portion 1011, and the fixing member 20 is provided with a rotation hole 201 and a fixing hole 202 that penetrate the thickness of the fixing member 20. The fixing hole 202 is provided for passing the connecting member 30 to fix the fixing member 20 relative to the first locking object; the rotation hole 201 is sleeved on the second portion 102 between the unlocking portion 1022 and the first portion 101, and the fixing member 20 is supported on the step portion 1011.

[0075] As an example, in some embodiments, the fixing member 20 adopts an elliptical plate-like structure, and fixing holes 202 are respectively provided at the two ends of the long axis of the fixing member 20, and the fixing member 20 is fixed to the display assembly 100 by inserting screws, rivets or pins in the fixing holes 202. A rotation hole 201 can be provided at the center of the fixing member 20.

[0076] In other embodiments, the radial dimensions of the first part 101 and the second part 102 can be consistent, that is, the design of the step portion 1011 is eliminated, and the rotating member 10 is prevented from being separated from the fixed member 20 by the mutual adaptation between the hole wall of the rotating hole 201 and the peripheral wall of the second part 102.

[0077] In some embodiments, the step portion 1011 is provided with a first stop structure 1012, the first stop structure 1012 includes a groove structure 1012a and a first stop portion 1012b, the groove structure 1012a extends along the circumferential direction to have a certain circumferential dimension, and the first stop portion 1012b is arranged on a side edge of the groove structure 1012a along the circumferential direction. The first stop portion 1012b can be a groove shape or a convex shape. In addition, the locking portion 1021 and the first stop portion 1012b are arranged opposite to each other along the axial direction. In this way, the rotation angles of the first stop portion 1012b and the locking portion 1021 are kept synchronous, when the locking portion 1021 is at the unlocking angle, the first stop portion 1012b is at the unlocking angle, and when the locking portion 1021 is at the locking angle and pressed on the second locking object, the first stop portion 1012b is also at the locking angle.

[0078] The fixing member 20 is provided with a second stop structure 203, which includes a protruding structure 2031, a second stop portion 2032 and a third stop portion 2033. The second stop portion 2032 and the protruding structure 2031 are arranged at intervals along the first direction. The protruding structure 2031 extends along the first direction with a certain circumferential dimension, and the degree of protrusion along the first direction gradually increases. The third stop portion 2033 is arranged at an end of the protruding structure 2031 away from the first stop portion 1012b. The circumferential dimension of the protruding structure 2031 is as small as possible from the circumferential dimension of the groove structure 1012a, so that the rotating member 10 has a larger rotation space between the locking angle and the unlocking angle.

[0079] The second stop portion 2032 may be in a groove shape or a convex shape. The third stop portion 2033 may be in a groove shape or a convex shape. The structures of the second stop portion 2032 and the third stop portion 2033 remain the same. One of the first stop portion 1012b and the second stop portion 2032 may be in a groove shape, and the other may be in a convex shape. One of the first stop portion 1012b and the third stop portion 2033 may be in a groove shape, and the other may be in a convex shape. The groove shape may be an elliptical or semicircular groove, and the convex shape may be an elliptical or semicircular convex. The groove shape and the convex shape are adapted to each other so that the operator can judge whether the rotating member 10 is rotated from the unlocking angle to the locking angle or from the locking angle to the unlocking angle.

[0080] On this basis, the rotating member 10 is configured to rotate along the first direction from the position where the first stop portion 1012b and the second stop portion 2032 are matched to the position where the locking portion 1021 presses on the second locking object and locks the first locking object and the second locking object when the first stop portion 1012b and the third stop portion 2033 are matched. Among them, the second stop portion 2032 is at the unlocking angle of the locking portion 1021, and when the first stop portion 1012b and the second stop portion 2032 are matched, the locking portion 1021 is at the unlocking angle. The third stop portion 2033 is at the locking position of the locking portion 1021, and when the first stop portion 1012b and the third stop portion 2033 are matched, the locking portion 1021 is at the locking angle and presses on the second locking object.

[0081] In some embodiments, the second stop structure 203 further includes a transition portion 2034 disposed on the protruding structure 2031. The structure of the transition portion 2034 is the same as that of the second stop portion 2032 and the third stop portion 2033. The number of the transition portions 2034 may be one or more. When there is one transition portion 2034, one transition portion 2034 and one third stop portion 2033 are arranged at intervals along the direction in which the protruding structure 2031 gradually increases in height. When there are multiple transition portions 2034, the multiple transition portions 2034 are arranged in sequence along the direction in which the protruding structure 2031 gradually increases in height, until the last transition portion 2034 is arranged at intervals with the third stop portion 2033. By setting the transition portion 2034, it is helpful for the operator to judge the rotation angle of the rotating member 10 when the rotating member 10 is rotated, and then judge the tightness of the rotating member 10 relative to the fixed member 20. At the same time, it is helpful to judge the rotation angle of the locking portion 1021 relative to the second locking object, which is helpful to coordinate the fixed member 20, the rotating member 10 and the second locking object to the best adaptation state.

[0082] In some embodiments, two first stop structures 1012 are provided on the step portion 1011, and two second stop structures 203 are provided on the fixing member 20. The two first stop structures 1012 are symmetrically arranged about the center of the rotating hole 201, and the two second stop structures 203 are symmetrically arranged about the center of the rotating hole 201. The two first stop structures 1012 and the two second stop structures 203 are adapted to each other one-to-one. The adaptation of the two first stop structures 1012 and the two second stop structures 203 improves the balance of the adjustment. In addition, the position of one of the first stop structures 1012 can be axially opposite to the unlocking portion 1022, which is conducive to the unlocking portion 1022 judging its rotation angle and unlocking degree with the help of the first stop structure 1012 and the second stop structure 203.

[0083] Reference Figures 5 to 8 As shown, another purpose of the embodiment of the present application is to provide a display device, which includes a display assembly 100 and a fixed housing 200, and a locking structure as described above. The first part 101 of the locking structure is connected to the display assembly 100 and is configured to be able to rotate relative to the display assembly 100. When the rotating member 10 rotates along a first direction, the locking portion 1021 presses on the fixed housing 200 and locks the fixed housing 200 and the display assembly 100. When the rotating member 10 rotates along a second direction, the locking portion 1021 is separated from the fixed housing 200 and the unlocking portion 1022 drives away from the fixed housing 200 to unlock.

[0084] In some embodiments, the display device includes a plurality of locking structures, which are sequentially arranged at intervals along the edge of the fixed housing 200. By providing a plurality of locking structures, the locking strength between different edge positions of the fixed housing 200 and different azimuth positions of the display assembly 100 can be enhanced, thereby improving the assembly stability and fastening of the entire display device.

[0085] The display device provided in the embodiment of the present application is applied with the locking structure provided in the present application to realize the locking and unlocking between the display assembly 100 and the fixed box 200. The locking structure can be selected to be rotated and mounted on the display assembly 100, and the locking structure can be rotated relative to the display assembly 100. The unlocking portion 1022 and the locking portion 1021 can lock or unlock the fixed box 200 and the display assembly 100 in different directions. With the locking structure provided in the present application, by rotating in the opposite direction, the locking portion 1021 can be locked or unlocked by the unlocking portion 1022. The locking degree between the display assembly 100 and the fixed box 200 can be adjusted according to the actual locking requirements without locking the two too much. Moreover, the processing accuracy of the fixed box 200 does not need to be precisely controlled, and it is only necessary that the locking portion 1021 can be smoothly pressed on the fixed box 200. Furthermore, the unlocking portion 1022 can smoothly drive the fixed housing 200 away from the display assembly 100, so that the display assembly 100 and the fixed housing 200 can be detached conveniently and quickly, and the processing cost of the fixed housing 200 is reduced.

[0086] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
