The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

The curling assembly is generally used in the fields of notebook computers, tablet computers, vehicles and the like, and as shown in fig. 1, the curling assembly comprises a scroll 100 'and a curling display module 200'. Currently, in order to realize the quick connection between the reel 100 ' and the rolled display module 200 ', a double-sided adhesive tape 300 ' is usually disposed between the reel 100 ' and the rolled display module 200 ' to adhere and fix the two. However, this connection method causes a problem that when the roll shaft 100 ' and the rolled display module 200 ' are separated, glue remains on the rolled display module 200 ' or the roll shaft 100 ', or the rolled display module 200 ' is damaged when being detached due to too strong adhesion.

To solve the above problem, as shown in fig. 2 to 7, the present embodiment provides a curling assembly, which includes a reel 100, a curling display module 200, at least one pin 1 and at least one socket 2, one of the pin 1 and the socket 2 is disposed on the reel 100, the other one is disposed on the curling display module 200, and the pin 1 can be inserted into the socket 2, so that the reel 100 and the curling display module 200 can be detachably connected. In this embodiment, due to the insertion relationship between the plug 1 and the socket 2 and the absence of glue between the plug 1 and the socket 2, no glue remains between the reel 100 and the curled display module 200 after separation. In addition, due to the insertion relationship between the plug 1 and the insertion hole 2, a force required for separation is smaller than that required for adhesion between the reel 100 and the rollable display module 200, so that the rollable display module 200 is not damaged when the rollable display module 200 is separated from the reel 100. The multiple fixing and separation of the curled display module 200 and the scroll 100 can be realized, and the service life of the curled display module 200 is prolonged.

Referring to fig. 2 and 3, the curling display module 200 includes a bearing layer 201 and a functional layer, which are stacked, wherein the bearing layer 201 includes a mounting portion, and an orthographic projection of the functional layer on the bearing layer 201 along the stacking direction Z does not overlap with the mounting portion; the bolt 1 is arranged on the mounting part and is arranged at the same side of the functional layer. Specifically, the length dimension of the carrier layer 201 is greater than the length dimension of the functional layer (dimension in the horizontal direction X), in other words, the difference L between the length dimension of the carrier layer 201 and the length dimension of the functional layer is greater than zero, and in the present embodiment, the insertion holes 2 are provided in the reel 100 accordingly. By virtue of the above dimensional constraints, a position is provided for the mounting of the plug 1 without affecting the processing and the function of the functional layer. Further, the mounting portion may include a plurality of openings or grooves in which the plug pin 1 is disposed. The first aspect of the arrangement can reduce the material consumption of the bearing layer 201, and save the cost; in the second aspect, guidance can be provided for installation of the bolt 1, and the installation speed of the bolt 1 is improved; in the third aspect, when the plug 1 is adhered to the bearing layer 201, the adhesion area between the bearing layer 201 and the plug 1 can be increased, and the firmness of connection can be improved.

Specifically, the bearing layer 201 includes a flexible cover plate, and the functional layer includes an optical cement 206, a polarizer 202, a screen 203, a support film 204, an optical cement 206, and a steel sheet 205, which are sequentially disposed from bottom to top. The functions of the components of the functional layer and the connection relationships between the components are well known to those skilled in the art, and therefore, the functions of the components of the functional layer and the connection relationships between the components are not described in detail herein.

Referring to fig. 3 and 5, in the present embodiment, in order to make the functional layer contact with the roll 100 after the insertion pin 1 and the insertion hole 2 are engaged, the top surface of the insertion pin 1 is higher than the top surface of the functional layer along the stacking direction Z, and the length dimension H of the insertion pin 1 exceeding the functional layer is less than or equal to the depth dimension H of the insertion hole 2. I.e. the length dimension H of the plug 1 above the functional layer (the distance between the top surface of the plug 1 and the top surface of the functional layer) is smaller than or equal to the depth dimension H of the receptacle 2. So set up, can guarantee that bolt 1 and jack 2 cooperate, realize that the functional layer can contact with spool 100. Preferably, the length dimension H that bolt 1 is higher than the functional layer equals the depth dimension H of jack 2, and above-mentioned setting makes more stable laminating of functional layer and spool 100, avoids hanging in the air or the extrusion appearing between the two, can make the functional layer crease appear when coiling curling display module assembly 200 under the two unsettled state, the condition that the functional layer was crushed by the pressure probably appears when the two extrudees.

With reference to fig. 2 and fig. 3, regarding the connection relationship between the plug 1 and the carrier layer 201, in this embodiment, specifically, the curled display module 200 further includes a glue layer 3, and the plug 1 is connected to the carrier layer 201 through the glue layer 3. The bolt 1 and the bearing layer 201 are connected in an adhesion mode, so that the operation is convenient, and the connection is firm.

Regarding the specific shape of the glue layer 3, in this embodiment, optionally, the glue layer 3 covers at least one side surface of the plug pin 1, and a distance from a top surface of the glue layer 3 to the carrier layer 201 is less than or equal to a distance from a top surface of the functional layer to the carrier layer 201 along the stacking direction Z. So set up, can avoid glue film 3 to cause the interference to the contact of functional layer and spool 100 when realizing that bolt 1 is connected through glue film 3 and bearer layer 201. Preferably, the distance from the top surface of the glue layer 3 to the carrier layer 201 is equal to the distance from the top surface of the functional layer to the carrier layer 201, i.e. the top surface of the glue layer 3 is flush with the top surface of the functional layer. Alternatively, the glue layer 3 may only cover one side of the plug pin 1, as long as it is ensured that the plug pin 1 is connected with the bearing layer 201 through the glue layer 3. Preferably, the cross-sectional shape of the glue layer 3 is U-shaped along the stacking direction Z, that is, the glue layer 3 wraps the end face (the end close to the bearing layer 201) and the side face of the plug pin 1. In this embodiment, the glue layer 3 may be formed by solidifying glue. This setting makes 1 part of bolt bury underground in glue film 3, has enlarged the area of contact of bolt 1 and glue film 3 for bolt 1 is fixed more firmly. Wherein, the glue film 3 that is located bolt 1 circumference is not higher than the top surface of functional layer, avoids causing the interference to the contact of functional layer and spool 100. In another embodiment of this embodiment, the adhesive layer 3 is in a sheet shape, and the adhesive layer 3 may be directly adhered between the bearing layer 201 and the end surface of the plug pin 1, in this embodiment, the adhesive layer 3 may be a double-sided adhesive tape.

Regarding the shapes of the plug pin 1 and the insertion hole 2, in the present embodiment, optionally, the inner contour shape of the insertion hole 2 and the outer contour shape of the plug pin 1 are adapted. Specifically, in the present embodiment, the plug 1 has a cylindrical shape for the convenience of design and processing. Of course, in other embodiments, the cross-sectional shape of the plug pin 1 along the horizontal direction X is an ellipse, or the cross-sectional shape of the plug pin 1 along the horizontal direction X is a polygon such as a triangle, a quadrangle, etc., and the cross-sectional shape is not limited thereto.

In this embodiment, regarding the number of the plugs 1 and the number of the jacks 2, optionally, the number of the plugs 1 and the number of the jacks 2 are all multiple, and the multiple plugs 1 can be inserted into the multiple jacks 2 in a one-to-one correspondence manner. The arrangement of the plurality of pins 1 and the jacks 2 makes the fixing of the curled display module 200 and the scroll 100 more firm; on the other hand, it is also helpful to align the rolled display module 200 with the reel 100, and prevent the rolled display module 200 from tilting when being wound on the reel 100.

When the plug pin 1 and the jack 2 are both one, the cross section of the plug pin 1 along the horizontal direction X is in a non-circular shape such as a triangle, a quadrangle or an ellipse, and the inner contour shape of the jack 2 is matched with the cross section shape of the plug pin 1. The arrangement can also complete the insertion of the curled display module 200 and the scroll 100, and because the cross section of the plug 1 is non-circular, the inner contour shape of the jack 2 is matched with the cross section shape of the plug 1, the curled display module 200 can be prevented from tilting when being wound on the scroll 100. When the number of the plug pins 1 and the number of the jacks 2 exceed one, the cross section of the plug pins 1 along the horizontal direction X can be circular, and can also be non-circular such as triangular, quadrilateral or elliptical, in the embodiment, the inner contour shape of the jacks 2 is not limited, as long as the plug pins 1 can be inserted into the jacks 2. Exemplarily, when the cross-sectional shape of the plug pin 1 along the horizontal direction X is a circle, the cross-sectional shape of the jack 2 along the horizontal direction X may be a circle, or may also be a non-circle such as a triangle, a quadrangle, or an ellipse, wherein when the cross-sectional shape of the jack 2 along the horizontal direction X may be a circle, and when the jack 2 and the plug pin 1 are in interference fit, the side wall of the jack 2 completely wraps the plug pin 1; when the cross section of the jack 2 along the horizontal direction X is in a shape of a triangle, a quadrangle or an ellipse and the like, and the jack 2 and the plug 1 are in interference fit, the plug 1 is tangent to the side wall of the jack 2. In addition, the cross section shape of the bolt 1 along the horizontal direction X is a non-circular shape such as a triangle, a quadrangle or an ellipse, the cross section shape of the jack 2 along the horizontal direction X can be a circular shape, and can also be a non-circular shape such as a triangle, a quadrangle or an ellipse, as long as the interference fit between the bolt 1 and the jack 2 can be ensured.

Preferably, in this embodiment, the material of the plug pin 1 is an elastic material. Elastic material's setting for behind the plug 1 and the jack 2 grafting, at the reel 100 on the roll up display module assembly 200 in-process of curling, when exerting oneself slightly, plug 1 can take place deformation, avoids curling display module assembly 200 to be damaged. Specifically, the plug 1 may be made of rubber. In order to improve the connection strength, in this embodiment, the plug pin 1 may further include a supporting member and a wrapping member, wherein the supporting member is wrapped inside the wrapping member, the wrapping member is made of an elastic material, and the supporting member may be made of a material with hardness exceeding a predetermined hardness. Further, the supporting member may be a material having a certain supporting strength, such as hard plastic or stainless steel. In this embodiment, the wrapping member covers a portion of the supporting member inserted into the insertion hole 2. The range setting enables the wrapping to be saved as much as possible, avoiding waste. Preferably, the length of the wrapping element along the extension direction of the supporting element is equal to the depth of the plug hole 2, so as to enlarge the contact area between the wrapping element and the plug hole 2 as much as possible, and further improve the connection strength between the plug pin 1 and the plug hole 2.

Optionally, the bolt 1 and the socket 2 are in interference fit. Specifically, referring to fig. 4 and 6, the outer diameter dimension R1 of the cross section of the plug pin 1 is greater than the inner diameter dimension R2 of the socket 2. With the help of the above-mentioned complex setting for the connection of bolt 1 and jack 2 is comparatively firm, avoids slight disturbance can be with curling display module assembly 200 and spool 100 separation, has improved the convenience of operation.
