Description

Technical Field

[0001] The present application belongs to the technical field of communication equipment, and specifically relates to an electronic device. Background Art

[0002] With the improvement of user demand and the development of technology, the screens of electronic devices are getting bigger and bigger. In order to take into account the large screen and the portability of electronic devices, electronic devices equipped with scroll screens are gradually favored by users. In order to adaptively support the flexible display screen, the electronic devices involved in the related technology adopt two comb teeth structures that can move relatively.

[0003] The two comb-tooth structures that cooperate with each other will cause serious friction when the flexible display screen is expanded or contracted, which will cause abnormal noise, which will undoubtedly affect the user's use. Summary of the invention

[0004] The purpose of the embodiments of the present application is to disclose an electronic device that can solve the problem that the comb-tooth structure used for support described in the background art generates abnormal noise during movement, thereby affecting user use.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, the present application discloses an electronic device, the disclosed electronic device comprises a first body, a second body, a connecting rod mechanism and a flexible display screen, the flexible display screen is connected to the first body and the second body, and the second body is movably arranged on the first body;

[0007] The link mechanism is rotatably connected to the first body and the second body respectively, and the link mechanism can be unfolded or folded in the moving direction of the second body as the second body moves relative to the first body;

[0008] When the electronic device is in an unfolded state, the link mechanism is unfolded to a first length in the moving direction of the second body, and the link mechanism, the first body and the second body jointly support the flexible display screen;

[0009] When the electronic device is in a folded state, the link mechanism is folded to a second length in the moving direction of the second body, and the flexible display screen is supported by at least the first body and the second body; the second length is smaller than the first length.

[0010] The technical solution adopted in this application can achieve the following beneficial effects:

[0011] The electronic device disclosed in the embodiment of the present application improves the structure of the electronic device in the related art, and is rotatably connected to the first body and the second body by setting a connecting rod mechanism, so that the electronic device can drive the connecting rod mechanism to switch between the unfolded state and the folded state during the switching between the folded state and the unfolded state, that is, during the movement of the second body relative to the first body, the second body can drive the connecting rod mechanism to switch between the unfolded state and the folded state. This switching between the unfolded state and the folded state can be easily achieved by setting fewer connecting rod mechanisms. Compared with the cooperation between the dense comb tooth structures, fewer connecting rod mechanisms are easier to form a structure with a smaller contact area with the flexible display screen, and then form a smaller contact area, so that when the connecting rod mechanism switches between the unfolded state and the folded state, no large friction will be generated between the connecting rod mechanism and the first body and the second body. Therefore, the technical solution adopted in the present application can alleviate the problem of serious friction between the two comb tooth structures during the unfolding or contraction of the flexible display screen.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The electronic device disclosed in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0033] like Figures 1 to 20 As shown, an embodiment of the present application discloses an electronic device, and the disclosed electronic device includes a first body 100, a second body 200, a connecting rod mechanism 300 and a flexible display screen.

[0034] The first body 100 and the second body 200 are the installation base of the electronic device and are also the main supporting components of the electronic device. The flexible display screen is a display element in the electronic device that can display content to the user. When the electronic device has a touch function, the flexible display screen can also be used as an operating area of ​​the electronic device. The connecting rod mechanism 300 can connect the first body 100 and the second body 200.

[0035] The flexible display screen is connected to the first body 100 and the second body 200, the second body 200 is movably arranged on the first body 100, the link mechanism 300 is rotatably connected to the first body 100 and the second body 200 respectively, and the link mechanism 300 can be unfolded or folded in the moving direction of the second body 200 as the second body 200 moves relative to the first body 100; when the electronic device is in the unfolded state, the link mechanism 300 is unfolded to a first length in the moving direction of the second body 200, and the link mechanism 300, the first body 100 and the second body 200 jointly support the flexible display screen. When the electronic device is in the folded state, the link mechanism 300 is folded to a second length in the moving direction of the second body 200, and the flexible display screen is supported by at least the first body 100 and the second body 200; the second length is less than the first length.

[0036] In the present application, the first body 100 is connected to the second body 200 through the connecting rod mechanism 300. When the electronic device needs to switch from the folded state to the unfolded state, the user can drive the second body 200 to move relative to the first body 100, so that the second body 200 can drive the connecting rod mechanism 300 to switch from the folded state to the unfolded state along the movable direction of the second body 200, and at the same time, the second body 200 drives the flexible display screen to be in a large-screen state, so as to meet the user's demand for a large screen. Conversely, when the electronic device needs to switch from the unfolded state to the folded state, the user can drive the second body 200 to move in a direction close to the first body 100, so that the second body 200 can drive the connecting rod mechanism 300 to switch from the unfolded state to the folded state, and at the same time, the second body 200 drives the flexible display screen to be in a small-screen state, so as to improve the portability of the electronic device, which is conducive to the user carrying the electronic device.

[0037] When the electronic device switches between different states, the relative movement between the second body 200 and the first body 100 is assisted by the link mechanism 300, and the link mechanism 300 does not generate friction with the first body 100 or the second body 200 during the switching between the unfolded state and the folded state, thereby solving the problem of abnormal noise generated by friction during the unfolding or contraction of the flexible display screen of the electronic device. At the same time, when the electronic device is in the unfolded state, the flexible display screen is supported by the support mechanism formed by the link mechanism 300, the first body 100 and the second body 200, thereby ensuring that the flexible display screen in the large-screen state can be well supported, and ensuring that the flexible display screen in the large-screen state has good support stability.

[0038] The electronic device disclosed in the embodiment of the present application improves the structure of the electronic device in the related art, and the connecting rod mechanism 300 is respectively connected to the first body 100 and the second body 200 for rotation, so that the electronic device can drive the connecting rod mechanism 300 to switch between the unfolded state and the folded state during the switching between the folded state and the unfolded state, that is, during the movement of the second body 200 relative to the first body 100, the second body 200 can drive the connecting rod mechanism 300 to switch between the unfolded state and the folded state. This switching between the unfolded state and the folded state can be easily achieved by setting fewer connecting rod mechanisms 300. Compared with the cooperation between the dense comb tooth structures, fewer connecting rod mechanisms 300 are easier to form a structure with a smaller contact area with the flexible display screen, and then form a smaller contact area, so that when the connecting rod mechanism 300 switches between the unfolded state and the folded state, no large friction will be generated between the connecting rod mechanism 300 and the first body 100 and the second body 200. Therefore, the technical solution adopted in the present application can alleviate the problem of serious friction between the two comb tooth structures during the unfolding or contraction of the flexible display screen.

[0039] In the electronic device disclosed in the embodiment of the present application, the link mechanism 300 may include a first link 310 and a second link 320, wherein the first end of the first link 310 is rotatably connected to the first body 100, the second end of the first link 310 is rotatably connected to the first end of the second link 320, and the second end of the second link 320 is rotatably connected to the second body 200, wherein: when the electronic device is in the unfolded state, the first link 310 and the second link 320 are unfolded; when the electronic device is in the folded state, the first link 310 and the second link 320 are overlapped. In this case, the link mechanism 300 including the first link 310 and the second link 320 can transform different relative positional relationships between the two, so that the link mechanism 300 can be easily switched between the unfolded state and the folded state.

[0040] Specifically, during the switching process of the electronic device from the folded state to the unfolded state, the second body 200 moves in a direction away from the first body 100, so that the second body 200 drives the second connecting rod 320 to move, and while the second connecting rod 320 moves with the second body 200, the first end of the second connecting rod 320 rotates with the second end of the first connecting rod 310, and the second connecting rod 320 also drives the second end of the first connecting rod 310 to move in a direction away from the first body 100. In this case, the angle between the first connecting rod 310 and the second connecting rod 320 gradually increases, and the total length of the first connecting rod 310 and the second connecting rod 320 in the moving direction of the second body 200 increases. At this time, the first connecting rod 310 and the second connecting rod 320 are in the unfolded state, which can realize the connection between the second body 200 and the first body 100 that are far away from each other, and can also realize the support of the extended part of the flexible display screen.

[0041] In the process of switching the electronic device from the unfolded state to the folded state, the second body 200 moves toward the direction close to the first body 100, so that the second body 200 drives the second connecting rod 320 to move. While the second connecting rod 320 moves with the second body 200, the first end of the second connecting rod 320 rotates with the second end of the first connecting rod 310, and the second connecting rod 320 also drives the second end of the first connecting rod 310 to move toward the direction close to the first body 100. In this case, the angle between the first connecting rod 310 and the second connecting rod 320 gradually decreases, and the total length of the first connecting rod 310 and the second connecting rod 320 in the moving direction of the second body 200 decreases. At this time, the first connecting rod 310 and the second connecting rod 320 are in an overlapping state, and the electronic device is in a folded state.

[0042] In order to enable the link mechanism 300 to switch between the unfolded state and the folded state, the link mechanism 300 can help improve the accuracy of the position of the second body 200 when it moves relative to the first body 100. In a further technical solution, the second end of the first link 310 and the first end of the second link 320 can be hingedly connected through a hinge shaft 330, and the first body 100 can be provided with an arc-shaped guide groove 110, and the end of the hinge shaft 330 extends into the arc-shaped guide groove 110 and cooperates with the arc-shaped guide groove 110 in its extension direction.

[0043] In the above case, in order to facilitate the staff to assemble the connecting rod mechanism 300, the second end of the first connecting rod 310 and the hinge shaft 330 can be made by an integrated injection molding process. In addition, since the arc-shaped guide groove 110 can achieve guiding cooperation with the end of the hinge shaft 330, when the connecting rod mechanism 300 switches between the unfolded state and the folded state, the end of the hinge shaft 330 is fixed to the moving track in the arc-shaped guide groove 110, so that the track of the second connecting rod 320 driven by the end of the hinge shaft 330 is relatively fixed. Since the second end of the second connecting rod 320 cooperates with the second body 200, when the movement track of the second connecting rod 320 is relatively determined, the second connecting rod 320 has a certain degree of limiting effect on the moving track of the second body 200 relative to the first body 100, which is conducive to improving the stability and accuracy of the position of the second body 200 when it moves relative to the first body 100.

[0044] In the electronic device disclosed in the embodiment of the present application, since the connecting rod mechanism 300 needs to switch between the unfolded state and the folded state more frequently during the switching of the electronic device between the unfolded state and the folded state, in the connecting rod mechanism 300, the first end of the first connecting rod 310, the portion of the first body 100 connected to the first end of the first connecting rod 310, the second end of the first connecting rod 310, the first end of the second connecting rod 320, the second end of the second connecting rod 320, and the portion of the second body 200 connected to the second end of the second connecting rod 320 will rotate and cooperate more frequently, thereby causing more serious wear.

[0045] In order to alleviate the wear of the above-mentioned parts that need frequent rotation and coordination, in an optional technical solution, the first end of the first connecting rod 310, the part of the first body 100 connected to the first end of the first connecting rod 310, the second end of the first connecting rod 310, the first end of the second connecting rod 320, the second end of the second connecting rod 320, and the part of the second body 200 connected to the second end of the second connecting rod 320 can all be wear-resistant parts. The wear-resistant part has high strength and hardness, so that the wear-resistant part can alleviate the wear caused by frequent rotation, which is beneficial to improve the service life of the above-mentioned rotating parts, and is beneficial to improve the service life of the electronic equipment. Specifically, the wear-resistant part can be made of polyoxymethylene (POM) plastic. Of course, the wear-resistant part can also be made of other materials with good wear resistance. This application does not limit the specific materials used in the wear-resistant part.

[0046] In the electronic device disclosed in the embodiment of the present application, the link mechanism 300 may include a first link 310 and a second link 320, the second body 200 may be provided with a first strip hole 210, the first body 100 may be provided with a second strip hole 120, the first end of the first link 310 is rotatably connected to the first body 100, the second end of the first link 310 is rotatably matched with the first strip hole 210, and can move along the first strip hole 210; the first end of the second link 320 is rotatably matched with the second strip hole 120, and can move along the second strip hole 120, and the second end of the second link 320 is rotatably matched with the second body 200. When the electronic device is in the unfolded state, the first link 310 and the second link 320 are unfolded, and the second end of the first link 310 is in position-limiting contact with the first end of the first strip hole 210, and the first end of the second link 320 is in position-limiting contact with the first end of the second strip hole 120. When the electronic device is in the folded state, the second end of the first connecting rod 310 is in limited contact with the second end of the first strip hole 210 , and the first end of the second connecting rod 320 is in limited contact with the second end of the second strip hole 120 .

[0047] In the above case, when the electronic device is in the unfolded state or the folded state, the second end of the first connecting rod 310 can be limitedly matched with the first end or the second end of the first bar hole 210, and the first end of the second connecting rod 320 can be limitedly matched with the first end or the second end of the second bar hole 120. In other words, no matter whether the electronic device is in the unfolded state or the folded state, the second end of the first connecting rod 310 and the first end of the second connecting rod 320 will respectively be limitedly matched with different ends of the first bar hole 210 and the second bar hole 120, so that when the user operates the electronic device to switch between the two states, the user can stop the unfolding or folding operation of the electronic device after the first connecting rod 310 and the second connecting rod 320 are respectively limitedly matched with the first bar hole 210 and the second bar hole 120, so that the first connecting rod 310 and the second connecting rod 320 have relatively accurate positions in the unfolded state and the folded state of the electronic device, which is conducive to improving the accuracy of the position of the second body 200 in the unfolded state and the folded state of the electronic device.

[0048] In order to reduce the space occupied by the link mechanism 300 when the electronic device is in the folded state, in a further technical solution, when the electronic device is in the folded state, the first link 310 and the second link 320 can be overlapped, and the first link 310 can be covered by the second body 200. In this case, since the first link 310 and the second link 320 are overlapped, the size of the electronic device in the width direction occupied by the first link 310 and the second link 320 is only the width of the first link 310. The first link 310 is covered by the second body 200, so that when the electronic device is in the folded state, the first link 310 and the second link 320 will not additionally occupy the size of the electronic device in the width direction, which is conducive to reducing the overall size of the electronic device in the folded state, and is used to reduce the overall occupied space of the electronic device. It should be noted that the width of the electronic device in the plane where the second body 200 moves is perpendicular to the direction of movement of the second body 200.

[0049] Due to different usage requirements of users, the electronic device disclosed in the embodiment of the present application needs to switch between the unfolded state and the folded state more frequently, so that the first end of the first connecting rod 310, the second end of the first connecting rod 310, the first end of the second connecting rod 320, the second end of the second connecting rod 320, the portion of the first body 100 where the second strip hole 120 is opened, and the portion of the second body 200 where the first strip hole 210 is opened will be limited and matched more frequently, thereby causing the above-mentioned portions that require limited and matched to produce more severe wear.

[0050] In order to alleviate the wear condition of the above-mentioned parts that need to be limited, in an optional technical solution, the first end of the first connecting rod 310, the second end of the first connecting rod 310, the first end of the second connecting rod 320, the second end of the second connecting rod 320, the part of the first body 100 where the second strip hole 120 is opened, and the part of the second body 200 where the first strip hole 210 is opened can all be wear-resistant parts. The strength and hardness of the wear-resistant part are both high, so that the wear-resistant part can alleviate the wear caused by frequent limited cooperation, which is beneficial to improve the service life of the above-mentioned parts that need to be limited, and is beneficial to improve the service life of the electronic equipment. Specifically, the wear-resistant part can be made of polyoxymethylene (POM) plastic. Of course, the wear-resistant part can also be made of other materials with better wear resistance. This application does not limit the specific materials used in the wear-resistant part.

[0051] In order to enable the second body 200 to return to the position where it should be when the electronic device is in the folded state more accurately, in any electronic device described above, optionally, the first body 100 may include a first limiting surface 130, and the second body 200 may have a second limiting surface 220 opposite to the first limiting surface 130, and the first limiting surface 130 and the second limiting surface 220 are distributed along the moving direction of the second body 200. When the electronic device is in the unfolded state, the first limiting surface 130 is separated from the second limiting surface 220; when the electronic device is in the folded state, the first limiting surface 130 is in limiting contact with the second limiting surface 220. In this case, the first limiting surface 130 and the second limiting surface 220 cooperate with each other in a limited position when the electronic device is in a folded state, thereby preventing the second body 200 from excessively moving relative to the first body 100 when the electronic device is switched from an expanded state to a folded state, thereby preventing the second body 200 from excessively approaching the first body 100 in the moving direction, which is beneficial to improving the position accuracy of the second body 200 of the electronic device in the folded state.

[0052] In a further technical solution, the edge of the second body 200 may be provided with a receiving notch 230. When the electronic device is in the folded state, the receiving notch 230 and the first limiting surface 130 enclose a first receiving space 500, and the second connecting rod 320 is located in the first receiving space 500. In this case, when the electronic device is in the folded state, the first receiving space 500 can be used as a space specifically for accommodating the second connecting rod 320, which is conducive to improving the stability of the second connecting rod 320 when the electronic device is in the folded state. In addition, the first receiving space 500 is enclosed with the first limiting surface 130 by providing the receiving notch 230 on the edge of the second body 200. In other words, the present application forms the first receiving space 500 by improving the structure of the second body 200 itself, thereby avoiding the need to set a space outside the first body 100 and the second body 200 in the electronic device to accommodate the second connecting rod 320, thereby saving the occupied space of the electronic device in the folded state.

[0053] In order to reduce the thickness of the electronic device, in the electronic device disclosed in the embodiment of the present application, the second body 200 may include a plate-like structure 240, and the surface of the second connecting rod 320 facing the flexible display screen is coplanar with the plate-like support surface of the plate-like structure 240. In this case, in the thickness direction of the electronic device, the second connecting rod 320 will not protrude from the plate-like structure 240, and the plate-like structure 240 will not protrude from the second connecting rod 320, so that the second connecting rod 320 and the plate-like structure 240 will not occupy too much of the size of the electronic device in the thickness direction, which is conducive to reducing the overall size of the electronic device. It should be noted that the thickness of the electronic device is the size of the electronic device in the direction perpendicular to the flexible display screen.

[0054] In order to enable the user to more accurately control the relative movement of the second body 200 with respect to the first body 100, in the electronic device disclosed in the embodiment of the present application, the electronic device may also include a guide mechanism 400, the guide mechanism 400 includes a guide seat 410, a guide rail 420 and a rolling body 430, the guide seat 410 is fixed to the first body 100, the guide rail 420 is slidably arranged in the guide groove 411 of the guide seat 410, and a plurality of rolling bodies 430 are arranged between the guide rail 420 and the guide groove 411, the guide rail 420 can be connected to the second body 200 by a plurality of screws, which is beneficial to improve the stability of the connection between the guide rail 420 and the second body 200.

[0055] In the above case, during the movement of the second body 200 relative to the first body 100, the guide groove 411 of the guide seat 410 and the guide rail 420 can achieve sliding cooperation, and by providing a plurality of rolling bodies 430 between the guide rail 420 and the guide groove 411, the sliding cooperation between the guide groove 411 and the guide rail 420 can be transformed into rolling cooperation between the guide rail 420 and the plurality of rolling bodies 430, which is conducive to reducing the friction force when the guide rail 420 moves in the guide groove 411, thereby facilitating the movement of the second body 200 relative to the first body 100.
