Abstract
Description
Technical Field
[0001] The present application relates to the technical field of ink screens, and in particular to a foldable ink screen. Background Art
[0002] Ink screen is a reflective display screen. When ambient light enters the screen, ink particles reflect the light out of the screen to achieve display. Compared with self-luminous electronic devices, ink screen devices are favored by users because they are less harmful to the eyes.
[0003] However, the electronic ink screens currently on the market usually only have single-screen functions. Users can only achieve multi-tasking and information display by switching screens or using multiple devices. However, this method is inconvenient to use, which limits its usage scenarios and takes up users' time and space. Utility Model Content
[0004] The present application provides a foldable ink screen, aiming to solve the technical problem that existing ink screens are inconvenient in multi-tasking and information display.
[0005] On the one hand, the present application provides a foldable ink screen, comprising a first sub-screen, a second sub-screen and a rotating mechanism, wherein the rotating mechanism is arranged between the first sub-screen and the second sub-screen, and is respectively driven and connected to the first sub-screen and the second sub-screen;
[0006] The rotating mechanism comprises a housing, a pair of first rotating shafts and a driving assembly;
[0007] The shell has a receiving cavity inside, and a first opening communicating with the receiving cavity is provided on its surface; each of the first rotating shafts includes a first end and a second end arranged opposite to each other, each of the first ends is located in the receiving cavity, and is transmission-connected to the driving assembly; each of the second ends is exposed to the outside of the shell from the first opening, and is fixedly connected to the corresponding first sub-screen or second sub-screen;
[0008] The driving assembly is disposed in the accommodating cavity, and is used for driving a pair of the first rotating shafts connected thereto to rotate relative to each other, so that the first sub-screen and the second sub-screen rotate in a direction toward or away from each other.
[0009] In the present application, a foldable ink screen is designed. Since the ink screen includes a first sub-screen and a second sub-screen, the first sub-screen and the second sub-screen can process different tasks or display different contents respectively, thereby improving the convenience of users in multi-tasking and information display. In addition, since the first sub-screen is fixedly connected to one of a pair of first rotating shafts, and the second sub-screen is fixedly connected to the other of the pair of first rotating shafts, when the driving mechanism drives the pair of first rotating shafts to rotate relative to each other, the first sub-screen and the second sub-screen rotate in a direction close to or away from each other under the driving action of the first rotating shaft connected thereto, so that the ink screen in the present application can be folded, which is conducive to reducing the use space of the ink screen. In addition, the rotating mechanism in the ink screen of the present application only includes a shell, a pair of first rotating shafts and a driving assembly, which has the advantages of simple structure and a small number of parts. In addition, since the rotating mechanism in the present application is provided with a shell, before assembling the electronic product, the pair of first rotating shafts and the driving assembly can be pre-installed in the shell, and the shell can protect the first rotating shaft and the driving assembly therein, thereby avoiding the problem of dust accumulation of the first rotating shaft and the driving assembly during storage, transportation or use, resulting in a decrease in control accuracy, and at the same time, it is conducive to improving the assembly efficiency of the electronic product.

Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.
[0026] At present, the electronic ink screens on the market usually only have single-screen functions. When using them, users can only achieve multi-tasking and information display by switching screens or using multiple devices. However, this method is inconvenient to use, which limits its usage scenarios and takes up users' time and space.
[0027] In view of this, the present application provides a foldable ink screen, in which the first sub-screen and the second sub-screen in the ink screen respectively process different tasks or display different contents, thereby improving the convenience of use for users in multi-tasking and information display. In addition, the first sub-screen and the second sub-screen can be folded under the action of the rotating mechanism, which is beneficial to reducing the use space of the ink screen. The rotating mechanism in the ink screen of the present application only includes a shell, a pair of first rotating shafts and a driving assembly, which has the advantages of simple structure and a small number of parts. The rotating mechanism in the present application is provided with a shell. Before assembling the electronic product, a pair of first rotating shafts and a driving assembly can be pre-installed in the shell. The shell can protect the first rotating shaft and the driving assembly therein, thereby avoiding the problem of dust accumulation on the first rotating shaft and the driving assembly during storage, transportation or use, resulting in a decrease in control accuracy, and at the same time is beneficial to improve the assembly efficiency of electronic products. For ease of understanding, the rotating mechanism and the ink screen in the present application are further described below in conjunction with the accompanying drawings.
[0028] See also Figures 1 to 10 , an embodiment of the present application provides a foldable ink screen, including a first sub-screen 200, a second sub-screen 300 and a rotating mechanism 100, wherein the rotating mechanism 100 is disposed between the first sub-screen 200 and the second sub-screen 300, and is driven and connected to the first sub-screen 200 and the second sub-screen 300, respectively. It should be noted that the number of rotating mechanisms 100 in the present application is not limited, and may be one or more (two or more). Specifically in this embodiment, the ink screen includes two rotating mechanisms 100, and the two rotating mechanisms 100 are arranged along the length direction of the first sub-screen 200 or the second sub-screen 300 (that is, Figure 7 The two rotating mechanisms 100 are arranged at intervals in the F1 direction in the figure. For example, the two rotating mechanisms 100 are arranged near the two ends of the first sub-screen 200 or the second sub-screen 300. The first sub-screen 200 and the second sub-screen 300 can rotate relative to each other under the action of the rotating mechanism 100 to unfold or fold the ink screen. Please refer to the following for details.
[0029] In the embodiments of this application, please refer to Figures 7 to 9, the rotating mechanism 100 includes a shell 110, a pair of first rotating shafts 120 and a driving assembly 130. The shell 110 provides a housing 111b for accommodating the driving assembly 130 and the pair of first rotating shafts 120. The shell 110 also fixes and protects the driving assembly 130 and the pair of first rotating shafts 120 therein, and forms part of the appearance decorative surface of the ink screen 1000 (that is, the rotating mechanism 100 is directly used as an appearance part for the ink screen 1000). Each first rotating shaft 120 is respectively connected to a display screen, that is, one of the first rotating shafts 120 is fixedly connected to the first sub-screen 200, and the other first rotating shaft 120 is fixedly connected to the second sub-screen 300. The pair of first rotating shafts 120 are connected by the driving assembly 130, so that the first sub-screen 200 and the second sub-screen 300 of the ink screen 1000 can rotate relative to each other to unfold or fold the ink screen 1000.
[0030] In the embodiment of the present application, the housing 110 has a receiving cavity 111b therein, and a first opening 112a (eg, Figure 8 ); each of the first rotating shafts 120 includes a first end 121 and a second end 122 that are arranged opposite to each other, the first end 121 of each of the first rotating shafts 120 is located in the accommodating cavity 111b and is in transmission connection with the driving assembly 130, the second end 122 of each of the first rotating shafts 120 is exposed to the outside of the shell 110 from the first opening 112a, and is fixedly connected to the corresponding first sub-screen 200 or second sub-screen 300. Specifically in this embodiment, a pair of the first rotating shafts 120 are arranged in parallel.
[0031] In the embodiment of the present application, the driving assembly 130 is disposed in the accommodating cavity 111b, and is used to drive a pair of the first rotating shafts 120 connected thereto to rotate synchronously relative to each other, so that the first sub-screen 200 and the second sub-screen 300 rotate in a direction closer to or away from each other.
[0032] It can be understood that in each rotating mechanism 100 of the present application, the second end 122 of one of the pair of first rotating shafts 120 can be fixedly connected to the first sub-screen 200, and the second end 122 of the other first rotating shaft 120 can be fixedly connected to the second sub-screen 300. When the user drives the first sub-screen 200 to rotate relative to the second sub-screen 300, since the first sub-screen 200 is fixedly connected to the second end 122 of a first rotating shaft 120, the first sub-screen 200 drives the first rotating shaft 120 fixedly connected thereto to rotate. At the same time, since the first ends 121 of the two first rotating shafts 120 are both located in the accommodating cavity 111b and are transmission-connected to the driving assembly 130, the first sub-screen 200 and the second sub-screen 300 can achieve synchronous rotation under the joint action of the pair of first rotating shafts 120 and the driving assembly 130.
[0033] It can be understood that since the ink screen in the present application includes a first sub-screen 200 and a second sub-screen 300, the first sub-screen 200 and the second sub-screen 300 can respectively process different tasks or display different contents, thereby improving the user's convenience in multi-tasking and information display.
[0034] It can be understood that since the first sub-screen 200 is fixedly connected to one of the pair of first rotating shafts 120, and the second sub-screen 300 is fixedly connected to the other of the pair of first rotating shafts 120, when the driving mechanism 100 drives the pair of first rotating shafts 120 to rotate relative to each other, the first sub-screen 200 and the second sub-screen 300 rotate in a direction closer to or away from each other under the driving action of the first rotating shaft 120 connected thereto, thereby allowing the ink screen in the present application to be folded, which is beneficial to reducing the usage space of the ink screen.
[0035] It can be understood that, compared with the prior art, the rotating mechanism 100 in the present application only includes a shell 110, a pair of first rotating shafts 120 and a driving assembly 130, which has the advantages of simple structure and a small number of parts. In addition, since the rotating mechanism 100 in the present application is provided with a shell 110, before assembling the electronic product, the pair of first rotating shafts 120 and the driving assembly 130 can be pre-installed in the shell 110, and the shell 110 can protect the first rotating shaft 120 and the driving assembly 130 therein, thereby avoiding the problem of reduced control accuracy caused by dust accumulation or damage of the first rotating shaft 120 and the driving assembly 130 during storage, transportation or use. The shell 100 in the rotating mechanism 100 can be directly used as an appearance part in the ink screen 1000, which is conducive to improving the assembly efficiency and aesthetics of the electronic product.
[0036] In some embodiments of this application, please refer to Figure 7 and Figure 8 , the second end 122 along its length direction (i.e. Figure 7The second end 122 is provided with a plurality of first threaded holes 122a in the F1 direction, and the second end is fixedly connected to the first sub-screen 200 or the second sub-screen 300 through the first threaded holes. Exemplarily, the second end 122 is in the shape of a plate, and a plurality of first threaded holes 122a are provided along its length direction. Specifically, the second end 122 is in the shape of a narrow strip-shaped flat plate, and the number of the first threaded holes 122a is two. This implementation improves the connection stability between each first rotating shaft 120 and the corresponding display screen by configuring the second end 122 to be in the shape of a narrow strip-shaped plate, and a plurality of first threaded holes 122a are provided in its length direction, and is suitable for display screens with narrow bezels.
[0037] In some embodiments of the present application, a limiting portion 123 is protruded from the surface of the first rotating shaft 120 between the first end 121 and the second end 122, and the limiting portion cooperates with the side wall of the shell 110 to limit the depth of the first rotating shaft 121 extending into the first opening 112a. For example, the first end 121 and the second end 122 are respectively the first rotating shaft 120 in the length direction (i.e., Figure 7 The limiting portion 123 is disposed between the first end 121 and the second end 122, the area of the plane formed by the intersection of the plane perpendicular to the direction of the first rotating shaft 120 and the limiting portion 123 (hereinafter referred to as the cross-sectional area) is greater than the area enclosed by the first opening 112a, and the area of the plane formed by the intersection of the plane perpendicular to the direction of the first rotating shaft 120 and the portion of the first rotating shaft 120 located between the first end 121 and the limiting portion 123 (hereinafter referred to as the cross-sectional area) is smaller than the area of the first opening 112a. In this embodiment, the limiting portion 123 is disposed between the first end 121 and the second end 122, and the cross-sectional area of the limiting portion 123 is greater than the area of the first opening 112a, and the cross-sectional area of the portion of the first rotating shaft 120 located between the first end 121 and the limiting portion 123 is smaller than the area of the first opening 112a. In this embodiment, a limiting portion 123 is provided on the first rotating shaft 120, and the limiting portion abuts against the shell 110 (for example, the first side plate 112) to limit the position during assembly, thereby facilitating the improvement of the assembly accuracy of the first rotating shaft 120. Exemplarily, the portion of the first rotating shaft 120 between the first end 121 and the limiting portion 123 is a uniform rod-shaped structure, and the cross-section of the portion of the first rotating shaft 120 between the first end 121 and the limiting portion 123 is square. The first opening 112a is a circular hole, and the limiting portion 123 is an annular truncated cone. After the first rotating shaft 120 is installed in place, the limiting portion 123 abuts against the side of the shell 110 away from the accommodating cavity 111b, and blocks and seals the first opening 112a.
[0038] In some embodiments of the present application, the drive assembly 130 includes a pair of driving gears 131, a pair of synchronous gears 132 located between the pair of driving gears 131, and a pair of second rotating shafts 133; each of the first ends 121 is fixedly connected to the corresponding driving gear 131, the second rotating shaft 133 is fixedly connected to the shell 110, and is arranged parallel to the first rotating shaft 120, each of the synchronous gears 132 is rotatably mounted on the second rotating shaft 133, the pair of synchronous gears 132 are meshed with each other, and the pair of driving gears 131 are transmitted and matched through the pair of synchronous gears 132.
[0039] Exemplarily, when the first sub-screen 200 and the second sub-screen 300 rotate toward each other, as shown in FIG. Fig.10 As shown, a driving gear 131 on the left side rotates in a clockwise direction, a driving gear 131 on the right side rotates in a counterclockwise direction, a synchronous gear 132 on the left side rotates in a counterclockwise direction, and a synchronous gear 132 on the right side rotates in a clockwise direction. In this embodiment, by setting a plurality of sets of gears that mesh with each other, the two first ends 121 of a pair of first rotating shafts 120 are connected through a plurality of sets of gear transmissions, so that the pair of first rotating shafts 120 can rotate synchronously. In addition, by setting a gear driving assembly 130, the pair of first rotating shafts 120 can be rotated and stay at any folding angle, so that the first sub-screen 200 and the second sub-screen 300 connected to the pair of first rotating shafts 120 have a fully unfolded state, a folded state, and a semi-expanded state. Wherein, when the ink screen is in a fully unfolded state, the two sub-screens are located on the same plane, that is, the first sub-screen 200 and the second sub-screen 300 are located on the same plane. When the ink screen is in a semi-expanded state, as shown in FIG. Figures 3 to 5 As shown, the included angle between the two sub-screens is greater than 0° and less than 180° (that is, the included angle between the first sub-screen 200 and the second sub-screen 300 is between 0° and 180°), or the included angle between the two sub-screens is greater than 180° and less than 360° (that is, the included angle between the first sub-screen 200 and the second sub-screen 300 is between 180° and 360°); when the ink screen is in a folded state, the two sub-screens are stacked (that is, the orthographic projections of the first sub-screen 200 and the second sub-screen 300 completely overlap).
[0040] It should be noted that in some other embodiments of the present application, the driving assembly 130 may also be provided with only a pair of first rotating shafts 120. In some other embodiments of the present application, the driving assembly 130 may also be a synchronous belt or a synchronous connecting rod, etc., which is not limited here.

This embodiment is arranged to increase the contact area between the first end 121 and the driving gear 131, and to improve the interaction force between the first end 121 and the driving gear 131. Exemplarily, the first end 121 is rod-shaped, the outer contour of the cross section of the first end 121 is square, the first assembly hole is square, and the size of the outer contour of the cross section of the first end 121 is similar to the size of the first assembly hole.

A pair of first openings 112a are provided on the first side plate 112, and each first opening 112a is arranged in a one-to-one correspondence with each second end 122. For example, the first end 121 is cylindrical, and the first opening 112a is a circular hole adapted to the cylinder, and each first rotating shaft 120 is rotatably arranged in the first opening 112a.
