The roll supporting device 1000 includes a housing 1, a shaft 2, a bracket module 3, a carrying module 4, an elastic member 5 and a stopping module 6. Wherein, casing 1 supplies to set up in the working face, and axostylus axostyle 2 is fixed in casing 1, and support module 3 is connected in casing 1, bears module 4 and is used for bearing flexible display device 2000, and with support module 3 interlock, and elastic component 5 connects axostylus axostyle 2 and bears module 4, and backstop module 6 sets up in casing 1 and is used for backstop to bear module 4.

Referring to fig. 4 and 5, the housing 1 includes a housing 11, an accommodating space 12, a through slot 13 and a first receiving slot 14. The housing 11 extends along a first axis X, surrounds the defined accommodating space 12, and has two spiral grooves 111, a main body 112, two side covers 113 and two positioning holes 114, wherein the spiral grooves 111 are formed on the two side covers 113 respectively with the shaft rod 2 as an axis, and are used for the sliding of the carrier module 4. The body 112 is disposed on the working surface and partially cylindrical, and the side covers 113 are connected to the body 112 opposite to each other and surround the body 112 to define the accommodating space 12. The positioning holes 114 are respectively formed on the two side covers 113 and are used for inserting the shaft rod 2. In other embodiments, the number of the positioning holes 114 and the number of the spiral grooves 111 are one, and are formed on at least one of the side covers 113. The through groove 13 is formed in the body 112 parallel to the first axis X and is communicated with the accommodating space 12, and the first accommodating groove 14 is formed in the body 112 and is communicated with the through groove 13 and is used for accommodating a part of the rack module 3.

Referring to fig. 6 to 8, the shaft 2 is disposed in the accommodating space 12 parallel to the first axis X. The shaft 2 and the positioning hole 114 have corresponding and non-circular radial cross sections, so that the shaft 2 can be inserted into the positioning hole 114 and fixed on the housing 11. The shaft 2 has a guiding groove 21 and two side edges 22, the guiding groove 21 is used to connect with the elastic member 5, and the guiding groove 21 extends to one side edge 22.

Referring to fig. 1, 2, and 7 to 10, the rack module 3 is connected to the housing 11 and can be switched between a fully folded position and a fully unfolded position along a second axis Y, wherein the second axis Y is not parallel to the first axis X (in the embodiment, the second axis Y is perpendicular to the first axis X). The bracket module 3 has a link assembly 31, a handle 32 and a second receiving slot 33, the link assembly 31 is pivotally disposed between the handle 32 and the body 112, the handle 32 is substantially parallel to the first axis X for being pulled by a user to unfold the flexible display device 2000, and the second receiving slot 33 is formed in the handle 32 parallel to the first axis X and is used for receiving the link assembly 31 together with the first receiving slot 14.

When the rack module 3 is switched to the fully folded position, the handle 32 is locked to the body 112 to fold the linkage 31, and when the rack module 3 is switched to the fully unfolded position, the handle 32 is away from the body 112 to unfold the linkage 31. Specifically, when the rack module 3 is in the fully folded position, the linkage 31 is completely received in the first receiving slot 14 and the second receiving slot 33, and the handle 32 covers the through slot 13. The support module 3 mainly provides support for the flexible display device 2000 and the carrying module 4, and in order to avoid suspending between the housing 11 and the handle 32 when the flexible display device 2000 and the carrying module 4 are unfolded outwards, so that the center of the flexible display device 2000 is recessed downwards, the linkage 31 provides support below the carrying module 4 to maintain the unfolded portions of the flexible display device 2000 and the carrying module 4 parallel to the working surface, so as to facilitate the viewing and the operation of a user.

In the embodiment, the link set 31 has four links, as shown in fig. 9 and 10, the links are pivoted to each other by two sets, and two ends of each set of links are pivoted to the body 112 and the handle 32, on the basis, when the support module 3 is at the fully folded position, the two links in each set can be completely folded and accommodated in the first accommodating groove 14 and the second accommodating groove 33, and when the support module 3 is at the fully unfolded position, the two links in each set can form an angle to support the carrying module 4 together.

Referring to fig. 11, the supporting module 4 is used for supporting the flexible display device 2000, and the supporting module 4 is partially fixed on the supporting module 3 to be linked with the supporting module 3. The carrier module 4 is a bendable hinge mechanism. The carrier module 4 includes a plurality of hinge plates 41, a plurality of pins 42, a first end 43 and a second end 44. The hinge pieces 41 and the pins 42 are substantially parallel to the first axis X, wherein the hinge pieces 41 are complementary to each other and arranged adjacently, and the adjacent hinge pieces 41 are pivotally connected by one of the pins 42, so that the carrier module 4 can achieve a winding effect through a plurality of pivotal connections. The first end 43 and the second end 44 are opposite ends of the carrier module 4, the first end 43 is pivotally connected to the handle 32 of the rack module 3, and the second end 44 is connected to the elastic member 5.

When the rack module 3 is in the fully folded position, the carrier module 4 is retracted into the accommodating space 12 (as shown in fig. 7) around the shaft 2, and when the rack module 3 is in the fully unfolded position, part of the carrier module 4 extends out of the housing 11 along the second axis Y through the through slot 13 (as shown in fig. 8).

Referring to fig. 6 to 8, the elastic element 5 is disposed in the accommodating space 12 and connects the shaft 2 and the supporting module 4. The elastic element 5 exerts an elastic force on the carrier module 4, so that the carrier module 4 tends to be wound in the accommodating space 12. In the embodiment, the elastic member 5 is a constant force spring and has a first connecting end 51 and a second connecting end 52 opposite to each other, the shaft 2 is inserted into the elastic member 5 and is fixedly connected to the first connecting end 51, and specifically, the first connecting end 51 enters the guide slot 21 through the side edge 22 and penetrates through the guide slot 21. The second connection end 52 is connected to the second end 44 of the carrier module 4. In other embodiments, the elastic member 5 may be replaced by other elastic components (such as a torsion spring), which is not limited herein.

The stop module 6 is disposed on the housing 11 and detachably abuts against the carrying module 4. The stopping module 6 includes a stopping block 61, a compression spring 62 and a pressing member 63. The stop block 61 is connected with the compression spring 62 and used for stopping the bearing module 4, and the compression spring 62 is connected with the shell 11 and pushes the stop block 61, so that the stop block 61 is inclined to be in contact with the bearing module 4. The pressing member 63 movably penetrates through the housing 11 and contacts with the stopping block 61, and when an external force is applied to the pressing member 63, the pressing member 63 pushes the stopping block 61 to be away from the bearing module 4 along a first direction and compresses the compression spring 62. The pressing member 63 has an inclined surface 631, the stop block 61 has two inclined surfaces 611, the inclined surfaces 631 and one of the inclined surfaces 611 are in contact with each other, and the other inclined surface 611 is used for contacting the carrier module 4. By the relative sliding between the inclined surfaces 631 and one of the inclined surfaces 611, and the bearing module 4 contacting the other inclined surface 611, the direction in which the pressing member 63 moves under the external force (i.e. the direction parallel to the second axis Y) is different from the first direction in which the stopper 61 slides under the pushing of the pressing member 63. In the present embodiment, the first direction is the same as a gravity direction (not shown), but not limited thereto.

The change of the reel supporting device 1000 between the states is further described below. The elastic force provided by the elastic member 5 makes the bearing module 4 tend to be inward-rolled, however, under a normal state, the pressing spring 62 tends to push the stop block 61 to move in a direction opposite to the first direction, so that the stop block 61 abuts against the bearing module 4, and therefore the inclined surface 611 of the stop block 61 abuts against the hinge plate 41 of the bearing module 4 (as shown in fig. 8) and generates a friction force with the bearing module 4 to stop the movement of the bearing module 4, and therefore, the support module 3 can be stopped at any position between the fully-folded position and the fully-unfolded position.

When a user applies an external force to the handle 32 and pulls the carrying module 4 outward, the stopping block 61 is driven by the carrying module 4 that is expanded outward to move toward the direction of compressing the compression spring 62 (i.e., move along the first direction), so that the degree of close contact between the carrying module 4 and the stopping block 61 is reduced, and the friction between the two is relatively reduced, so that the resistance applied to the user when pulling the carrying module 4 to expand outward is not large. When the user removes the external force, the carrier module 4 is stopped by the stopper module 6, and the rack module 3 is stopped at any position between the fully folded position and the fully unfolded position. In contrast, when the user presses the pressing member 63 (as shown in fig. 7) to retract the carrier module 4, the inclined surface 631 of the pressing member 63 and the inclined surface 611 of the stopping block 61 move the stopping block 61 toward the compressed spring 62, so that the stopping module 6 is separated from the carrier module 4, and at this time, the elastic force of the elastic member 5 retracts the carrier module 4 into the accommodating space 12 and the support module 3 is switched to the fully retracted position. Similarly, during the retracting process, once the user no longer presses the pressing member 63, the stopping block 61 tends to return to contact with the supporting module 4, so that the supporting module 3 stops at any position between the fully folded position and the fully unfolded position, and on the basis of this, the degree of the flexible display device 2000 exposed to the housing 11 can be adjusted, i.e. the operable area of the user can be adjusted.

To sum up, through the combination of the hinge mechanism, elastic component and backstop module, the utility model discloses a spool formula strutting arrangement can operate the use intuitively, and the pulling handle can expand flexible formula display device to the location to the accessible pressing part is packed up fast, accords with the user demand and operates simply.

The above embodiments are only used to illustrate the embodiments of the present invention and to explain the technical features of the present invention, and are not used to limit the protection scope of the present invention. All changes and equivalent arrangements which may be easily accomplished by those skilled in the art are intended to be within the scope of the present invention, which is to be accorded the full scope of the appended claims.
