[0040] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0041] Reference Figures 1 to 8 The housing of the first embodiment of the present application is applied to the field of screens, especially the switching application of portable hand-painted screens in different working modes, mainly to solve the problems of friction powder shedding, wear and loosening of the cam pre-compression caused by wear on the pressure surface of the left and right brackets of the screen when the hand-painted screen switches between the horizontal and inclined working states. The housing includes a shell assembly 100, a bracket assembly 200, a shaft component 300, a pre-compression structure 400 and a wear-resistant sheet component 500.

[0042] The shell assembly 100 is provided with an assembly structure 110; a cam structure 201 is provided at one end of the bracket assembly 200, and a mounting hole 202 extending axially is formed in the cam structure 201; the shaft component 300 is used to pass through the assembly structure 110 and the mounting hole 202, so that the bracket assembly 200 can be rotatably arranged on the shell assembly 100; the pre-pressing structure 400 is arranged on the shell assembly 100 and is used to pre-press the cam structure 201; the wear-resistant sheet component 500 is arranged on the surface of the cam structure 201 and is located between the contact surfaces of the pre-pressing structure 400 and the cam structure 201.

[0043] It can be understood that the assembly structure 110 is used for the shaft component 300 to pass through, so that after the shaft component 300 passes through the assembly structure 110 and the mounting hole 202, the bracket assembly 200 can swing around the shaft component 300 and open or close relative to the housing assembly 100. In some embodiments, the assembly structure 110 is formed on the housing assembly 100 and is an integral structure with the housing assembly 100 and is manufactured as a whole. In other embodiments, the assembly structure 110 is assembled on the housing assembly 100 in a detachable or non-detachable manner, and the two are manufactured by a corresponding production method and then connected and assembled.

[0044] It is understandable that there is a pre-compression amount between the pre-compression structure 400 and the cam structure 201, and the pre-compression structure 400 is used to compress the cam structure 201, so that the bracket assembly 200 can well maintain the relative position relationship with the housing assembly 100. In some embodiments, the pre-compression structure 400 is formed on the housing assembly 100 and is an integral structure with the housing assembly 100 and is manufactured as a whole. In other embodiments, the pre-compression structure 400 includes a fixing sheet component 401, which is assembled on the housing assembly 100 in a detachable or non-detachable manner, and the two are manufactured by a corresponding production method and then connected and assembled.

[0045] It should be noted that, based on the setting of the wear-resistant sheet component 500, the wear resistance of the rotating pressure contact surface can be improved, so that the bracket assembly 200 can still ensure sufficient pre-stress under the condition of frequent opening and closing rotation, so that it has a stable supporting effect and enables the user to use it stably when the bracket is in the open state. The wear-resistant sheet component 500 and the cam structure 201 of the bracket assembly 200 are assembled with each other and become a whole, thereby achieving the effect of comprehensively enhancing the wear resistance of the bracket cam friction surface.

[0046] Reference Figures 1 to 8The shell of the first aspect of the embodiment of the present application limits the cam structure 201 and ensures the pre-compression amount through the pre-compression structure 400, so that the bracket assembly 200 can be more stable when in use. The wear-resistant sheet component 500 is in contact with the pre-compression structure 400, so that the bracket assembly 200 can reduce the wear caused by opening and closing during normal opening and closing, thereby ensuring the user experience and extending the product life.

[0047] In some embodiments of the present application, a mounting groove 203 extending in the circumferential direction is formed on the surface of the cam structure 201, and the wear-resistant sheet component 500 is detachably arranged in the mounting groove 203, so that when the bracket assembly 200 rotates, the pre-pressing structure 400 can slide and abut against the wear-resistant sheet component 500 in the circumferential direction. It can be understood that in order to ensure that the pre-pressing force of the bracket assembly 200 is sufficient, the pre-pressing structure 400 always abuts against the wear-resistant sheet component 500, so when the bracket assembly 200 rotates, there is actually a relative movement between the pre-pressing structure 400 and the wear-resistant sheet component 500 in the circumferential direction. In this regard, the mounting groove 203 is adapted to be arranged according to this direction, so that after the wear-resistant sheet component 500 is installed in the mounting groove 203, it can always abut against the pre-pressing structure 400, thereby improving the wear resistance of the cam friction surface.

[0048] The detachable arrangement makes it easier to replace and repair the wear-resistant sheet component 500. In other embodiments, the wear-resistant sheet component 500 is arranged in the assembly groove 203 in a non-detachable manner. In this embodiment, when the wear-resistant sheet component 500 needs to be replaced, the entire bracket assembly 200 can be directly replaced.

[0049] In some embodiments of the present application, the wear-resistant sheet component 500 includes a first wear-resistant surface 510, an arc surface portion 520 and a straight edge portion 530. The first wear-resistant surface 510 is used to contact the pre-pressing structure 400 and is provided with a connection hole for connection. Each arc surface portion 520 is respectively arranged at both ends of the first wear-resistant surface 510 in the circumferential direction. Each straight edge portion 530 is respectively connected to the arc surface portion 520, so that the wear-resistant sheet component 500 can be fitted on the assembly groove 203. It can be understood that the first wear-resistant surface 510 is used to contact the pre-pressing structure 400 and can be processed into a shape that adapts to the contour of the cam structure 201. The arc surface portion 520 plays a transition role. The straight edge portion 530 is used to ensure that the wear-resistant sheet component 500 can be embedded in the assembly groove 203. Based on the structural design of the wear-resistant sheet component 500, the connection between the wear-resistant sheet component 500 and the cam structure 201 can be smoothly transitioned without affecting normal use.

[0050] In some embodiments, the wear-resistant sheet component 500 includes a wear-resistant sheet body made of a wear-resistant metal material, such as stainless steel or beryllium copper, which can greatly increase the wear resistance and extend the service life. At the same time, it can prevent the cam from generating powder due to friction during the opening and closing process of the bracket, thereby preventing the bracket from becoming weak, loose, and other problems due to excessive gaps caused by wear.

[0051] In some embodiments of the present application, the pre-pressing structure 400 includes a fixing sheet component 401, and the fixing sheet component 401 includes a mounting portion 410, an elastic arm 420 and a pre-pressing end 430. The mounting portion 410 is used to be arranged on the housing assembly 100, one end of the elastic arm 420 is used to connect the mounting portion 410, and the other end of the elastic arm 420 is used to connect the pre-pressing end 430, and the pre-pressing end 430 is used to abut against the wear-resistant sheet component 500. It can be understood that the mounting portion 410 is arranged on the housing assembly 100 as a bearing base, and the elastic arm 420 has elasticity so that the pre-pressing end 430 can reliably cling to the wear-resistant sheet component 500. In some embodiments, the mounting portion 410 is provided with a hole for the connecting member to pass through and be installed on the housing assembly 100, so that the fixing sheet component 401 can be reliably installed on the housing assembly 100. In some embodiments, the connecting member is a detachable connecting member such as a threaded fastener to facilitate the replacement of the fixing sheet component 401.

[0052] In some embodiments, the elastic arm 420 includes a plurality of continuous bending portions 421 , and each bending portion 421 can provide an elastic preload force to ensure that the preload strength of the bracket assembly 200 is sufficient.

[0053] In some embodiments, the pre-pressing end 430 includes a second wear-resistant surface 431 arranged in a circular arc, so as to improve the wear resistance of the pre-pressing end 430 .

[0054] In some embodiments of the present application, the bracket assembly 200 includes a vertical pad 210, a flat pad 220, a decorative sheet 230 and a bracket body 240. The other end of the bracket body 240 opposite to the cam structure 201 is provided with a connecting portion, the vertical pad 210 is detachably arranged on the connecting portion, the flat pad 220 is located on a surface relatively far from the housing assembly 100, and the decorative sheet 230 is located on a surface relatively close to the housing assembly 100. It can be understood that the bracket assembly 200 can be supported by the vertical pad 210 when in the open state, and can be supported by the flat pad 220 when in the closed state. The decorative sheet 230 is located on the relatively inner side of the bracket body 240, so that the bracket assembly 200 can play a decorative function when it is opened.

[0055] In some embodiments, the vertical pad 210 and the flat pad 220 are made of silicone pads, which can enhance the friction with the desktop and have an anti-slip effect.

[0056] In some embodiments, the support assembly 200 includes a support body 240 made of metal die-casting to increase the anti-deformation strength.

[0057] In some embodiments of the present application, the housing assembly 100 is provided with a positioning structure 120 for positioning the shaft component 300. It is understandable that the positioning structure 120 can ensure the smooth operation of the shaft component 300, so that the bracket assembly 200 can be smoothly opened or closed.

[0058] In some embodiments, the positioning structure 120 is formed on the housing assembly 100 and is an integral structure and manufactured integrally with the housing assembly 100. In other embodiments, the positioning structure 120 is assembled on the housing assembly 100 in a detachable or non-detachable manner, and the two are manufactured by corresponding production methods and then connected and assembled.

[0059] In some embodiments of the present application, the positioning structure 120 includes a first positioning portion 121 and a second positioning portion 122, and the first positioning portion 121 and the second positioning portion 122 are respectively arranged on both sides of the axis direction of the shaft component 300, so that the first positioning portion 121 and the second positioning portion 122 can cooperate to position the shaft component 300. It can be understood that through the adaptability design of the first positioning portion 121 and the second positioning portion 122, the shaft component 300 is well limited to a preset position on the housing assembly 100, thereby improving the rotation accuracy of the shaft component 300.

[0060] In some embodiments, the first positioning portion 121 includes a connecting column and a connecting piece detachably disposed on the connecting column, and the second positioning portion 122 is a limiting bone or a limiting rib. When installing the rotating shaft component 300, the rotating shaft component 300 is first installed with the second positioning portion 122 as a reference, and then the connecting piece is installed on the connecting column to limit the rotating shaft component 300, thereby utilizing the first positioning portion 121 and the second positioning portion 122 to achieve a positioning effect.
