Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

A slidably telescoping flexible spool mechanism 100, a flexible spool assembly, and a flexible electronic device 1000 according to embodiments of the present utility model are described below with reference to fig. 1-14.

The flexible reel mechanism 100 capable of sliding and stretching comprises a flexible supporting assembly 1, a sliding limiting piece 2 and a rotating module 3.

The flexible supporting assembly 1 comprises a first supporting member 11 and a second supporting member 12, the second supporting member 12 is nested in the first supporting member 11, the first supporting member 11 and the second supporting member 12 can be unfolded and folded along the length direction of the flexible reel mechanism 100, and the first supporting member 11 is provided with a guide hole 114 extending along the length direction of the flexible reel mechanism 100; the sliding limiting piece 2 is connected with the second supporting piece 12, and the sliding limiting piece 2 is movably matched in the guide hole 114 along the length direction of the flexible reel mechanism 100; the rotation module 3 comprises a flexible pulling member 31 and a transmission assembly 32, and the transmission assembly 32 drives the flexible pulling member 31 to move so as to drive the first supporting member 11 and the second supporting member 12 to change between unfolding and folding. It can be understood that the sliding limiting member 2 is disposed in the guiding hole 114 in a penetrating manner, two sides of the guiding hole 114 in the length direction can limit the sliding travel of the first supporting member 11 and the second supporting member 12, and the length of the guiding hole 114 in the flexible reel mechanism 100 is greater than the length of the sliding limiting member 2 in the flexible reel mechanism 100, so that the sliding limiting member 2 has enough space to move.

According to the flexible reel mechanism 100 capable of sliding and stretching, disclosed by the embodiment of the utility model, the guide hole 114 is formed in one support piece (the first support piece 11), the second support piece 12 can move along the length direction of the flexible reel mechanism 100 relative to the first support piece 11, the guide hole 114 can limit the travel of the sliding limiting piece 2 in the moving direction, the sliding limiting piece 2 connected with the second support piece 12 is matched in the guide hole 114, the wall surface of the guide hole 114 can be mechanically restrained and limited in two states between unfolding and folding, and the problem that a screen is torn due to the failure of a driving piece (motor delay) is effectively avoided. Thus, the flexible reel mechanism 100 has an advantage of high safety.

In addition, compared with the related art, since one side of the splice groove is an opening, when the splice groove is unfolded and folded, the splice groove can be moved out of the splice groove due to steps (particularly in an unfolded state) generated by processing and assembling, so that the problem of poor smoothness of motion obstruction of the moving part is caused. The guide hole 114 replaces the related art splice groove structure, so that the problem of motion blockage caused by steps generated by splicing can be avoided. Thus, the flexible reel mechanism 100 has an advantage of good smoothness in sliding expansion and contraction. Therefore, the sliding limiting members 2 are all arranged in the guide holes 114, and the falling phenomenon of the second supporting member 12 caused by gravity due to the fact that part of the sliding limiting members 2 are pulled out of the splicing groove is avoided. Thus, the flexible reel mechanism 100 further improves the smoothness of the slip expansion and contraction.

Therefore, the flexible reel mechanism 100 capable of sliding and stretching according to the embodiment of the utility model has the advantages of good sliding and stretching smoothness and high reliability.

Optionally, the sliding limiter 2 is slidably or rotatably fitted in the guide hole 114 along the length direction of the flexible reel mechanism 100.

Specifically, the first supporting piece 11 is slidably connected with the second supporting piece 12, the first supporting piece 11 and the second supporting piece 12 are nested, when moving, the second supporting piece 12 can move towards the inside of the first supporting piece 11, the second supporting piece 12 is completely contained in the first supporting piece 11, and at the moment, the flexible reel mechanism 100 is in a folded state; the second support 12 moves outwardly from the first support 11 until the limit position stops, at which point the flexible reel mechanism 100 is in a fully extended state.

Moreover, since the first supporting member 11 is slidably connected with the second supporting member 12, a step is formed therebetween, that is, the upper surface of the first supporting member 11 is higher than the upper surface of the second supporting member 12, and at this time, if the flexible screen 400 is directly covered on the first supporting member 11 and the second supporting member 12, the surface of the flexible screen 400 is uneven; in order to make the upper surfaces of the two be in the same plane, a common solution is to provide a flexible pulling member 31 on the upper surface of the second support member 12 to solve the problem of the step difference. The flexible screen 400 is covered on the upper surface of the first supporting piece 11 and the flexible traction piece 31 of the rotating module 3, and the thickness of the flexible screen just compensates the step difference between the upper surface of the second supporting piece 12 and the upper surface of the first supporting piece 11, so that the upper surface of the first supporting piece 11 and the upper surface of the flexible traction piece 31 are in the same plane, and the surface of the flexible screen 400 attached to the surface is flat.

As shown in fig. 4 and 6, the first supporting member 11 includes a first supporting plate 111, a first limiting plate 112 and a second limiting plate 113, the first limiting plate 112 and the second limiting plate 113 are disposed on both sides of the first supporting plate 111 along a width direction of the flexible reel mechanism 100, guide holes 114 are formed in the first limiting plate 112 and the second limiting plate 113, the first supporting plate 111, the first limiting plate 112 and the second limiting plate 113 define a receiving portion, and the second supporting member 12 is received in the receiving portion when being folded.

The slidable and telescopic flexible reel mechanism 100 according to the embodiment of the present utility model divides the first supporting member 11 into a first supporting plate 111, a first limiting plate 112 and a second limiting plate 113, and defines a receiving portion for receiving the second supporting member 12 in the first supporting plate 111, the first limiting plate 112 and the second limiting plate 113. The first support plate 111 and the first limiting plate 112 located at both sides of the flexible reel mechanism 100 in the width direction may limit the structure of the second support 12. Thus, the flexible reel mechanism 100 has the advantages of simple structure and good stability.

As shown in fig. 9, 10 and 14, the guide hole 114 may be an oblong hole, and the length direction of the oblong hole coincides with the length direction of the flexible reel mechanism 100. It will be appreciated that the first support 11 has a guide hole 114 extending in the slip telescopic direction. Thus, the guide hole 114 is formed as a oblong hole, and the problem that the sliding limiting member 2 is locked at both sides of the guide hole 114 is avoided.

As shown in fig. 4, 8 and 9, the sliding limiter 2 includes a first limiter 21 and a second limiter 22, the first limiter 21 and the second limiter 22 are correspondingly disposed on both sides of the width direction of the second support 12, and the first limiter 21 and the second limiter 22 are slidably or rotatably fitted in the guide holes 114 of the first limiter plate 112 and the guide holes 114 of the second limiter plate 113 in a one-to-one correspondence.

The flexible spool mechanism 100 of the embodiment of the present utility model is configured by dividing the slip stopper 2 into the first stopper 21 and the second stopper 22, and disposing the first stopper 21 and the second stopper 22 on both sides (e.g., left and right sides shown in fig. 3 and 4) of the second support 12 in the width direction, respectively. Thus, the flexible reel mechanism 100 helps to promote coordination of movement of the second support 12.

As shown in fig. 9 to 11, each of the first stopper 21 and the second stopper 22 includes a support bearing set 221 and a slide bar set 222, the support bearing set 221 is rotatably sleeved on the slide bar set 222, the slide bar set 222 is connected with the second support 12, and the support bearing set 221 is rotatably fitted in the guide hole 114.

According to the sliding telescopic flexible scroll mechanism 100 provided by the embodiment of the utility model, the supporting bearing group 221 is matched with the guide hole 114 in a rotating way so as to realize the sliding of the sliding or rolling piece in line contact or point contact, and further reduce the resistance of the first supporting piece 11 and the second supporting piece 12 in the transition between unfolding and folding. Thereby, the flexible reel mechanism 100 improves the smoothness of the sliding fit of the flexible reel mechanism 100.

As shown in fig. 9 to 11, the support bearing set 221 includes a first bearing 2211 and a second bearing 2212, the slide bar set 222 includes a plurality of slide bars disposed at intervals along the length direction of the flexible reel mechanism 100, the first bearing 2211 and the second bearing 2212 are connected to the second support 12 by the slide bars, the guide hole 114 has a first mating wall 1141 and a second mating wall 1142 disposed opposite to each other along the thickness direction of the flexible reel mechanism 100, the first bearing 2211 is slidably mated with the first mating wall 1141 and has a gap with the second mating wall 1142, and the second bearing 2212 is slidably mated with the second mating wall 1142 and has a gap with the first mating wall 1141. It is to be understood that the first bearing 2211 and the second bearing 2212 have a height difference in the thickness direction (for example, the up-down direction shown in fig. 5) of the flexible reel mechanism 100.

The slidably retractable flexible spool mechanism 100 of the present embodiment divides the support bearing set 221 into the first bearing 2211 and the second bearing 2212, and the first bearing 2211 is slidably engaged with the first engaging wall 1141 with a gap between the second engaging wall 1142, and the second bearing 2212 is slidably engaged with the second engaging wall 1142 with a gap between the first engaging wall 1141. So that the positioning of the first support 11 and the second support 12 in the thickness direction of the flexible reel mechanism 100 is defined (displacement of the first support 11 and the second support 12 in the thickness direction of the flexible reel mechanism 100 is prevented) by the height difference of the first bearing 2211 and the second bearing 2212 in the thickness direction of the flexible reel mechanism 100. Thus, the flexible reel mechanism 100 helps to promote the stability of the sliding of the flexible support assembly 1. Meanwhile, the high-low arrangement of the first bearing 2211 and the second bearing 2212 can reduce the assembly difficulty (the overall assembly difficulty is reduced by 40%), and the assembly efficiency is improved.

In addition, the contact area between the supporting bearing set 221 and the wall surface of the chute is further reduced. Therefore, the moving resistance is further reduced, the problem of friction blockage caused by gravity is avoided, and the moving smoothness is further improved.

Alternatively, as shown in fig. 8 to 11, the number of the first bearings 2211 and the second bearings 2212 may be plural, the first bearings 2211 and the second bearings 2212 having plural, the plural first bearings 2211 and the plural second bearings 2212 being alternately disposed in the guide hole 114 along the length direction of the flexible reel mechanism 100 along the second support 12.

Thus, the flexible reel mechanism 100 helps to achieve synchronicity and stability of the sliding fit of the first support 11 and the second support 12 in the flexible support assembly 1.
