Abstract
Description
Technical Field
[0001] The present application belongs to the field of communication technology, and specifically relates to an electronic device. Background Art
[0002] With the development of science and technology, people are becoming more and more dependent on electronic devices. In order to improve the portability and comfort of electronic devices, the application scope of foldable electronic devices is becoming wider and wider.
[0003] In the related art, foldable electronic devices rely on a hinge mechanism to achieve folding and unfolding. The hinge mechanism includes a base, a swing arm and a frame assembly. The swing arm is rotatably connected to the base, and the swing arm is slidably connected to the frame assembly. During the folding or unfolding process of the foldable electronic device, the frame assembly drives the swing arm to rotate relative to the base. At the same time, the frame assembly and the swing arm slide relative to each other to prevent the hinge mechanism from getting stuck and ensure the smooth folding and unfolding process. However, when the foldable electronic device in the folded state falls, the frame assembly will also slide relative to the swing arm and squeeze the display screen, making it easy for the display screen to collide with other components and damage the foldable electronic device. Utility Model Content
[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem of low reliability of foldable electronic devices when they fall in the related art.

[0006] The electronic device has a folded state. When the electronic device is in the folded state, the frame assembly and the connecting plate are limited in a first direction by the first limiting structure and the second limiting structure, and the connecting plate and the swing arm are limited in a second direction, and the angle between the first direction and the second direction is less than 90°.
[0007] In an embodiment of the present application, when the electronic device is in a folded state, the first limiting structure and the second limiting structure are used to achieve limiting cooperation between the connecting plate and the frame assembly in a first direction. At the same time, the connecting plate and the swing arm are limited in the second direction, and the angle between the first direction and the second direction is less than 90°, thereby achieving limiting cooperation among the swing arm, the connecting plate and the frame assembly in sequence, and achieving relative fixation between the swing arm and the frame assembly to avoid sliding of the frame assembly relative to the swing arm. Then, when the electronic device in the folded state falls, the frame assembly will not slip relative to the swing arm, thereby avoiding squeezing the display screen of the electronic device, and further avoiding collision of the display screen with other components to damage the electronic device, which is beneficial to improving the reliability of the electronic device when it falls.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to 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 provided 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] Please refer to Figure 1-Figure 14 The electronic device disclosed in the embodiment of the present application includes a base 100, a frame assembly, a swing arm 200 and a connecting plate 300, wherein the base 100 serves as an installation base for the frame assembly, the swing arm 200 and the connecting plate 300, and the swing arm 200 is rotatably connected to the base 100. Optionally, as Figure 3 and Figure 4 As shown, the base 100 is provided with a rotating shaft 110; Figure 5-Figure 7 As shown, the swing arm 200 is provided with a cylinder 240, and the cylinder 240 is sleeved on the outside of the rotating shaft 110. The swing arm 200 can rotate relative to the rotating shaft 110, so that the swing arm 200 can rotate relative to the base 100. The swing arm 200 and the base 100 can also be rotatably connected in other ways.
[0034] The connecting plate 300 is located between the swing arm 200 and the frame assembly, and the connecting plate 300 and the frame assembly can move relative to each other, and the swing arm 200 and the connecting plate 300 can move relative to each other, and the frame assembly and the swing arm 200 are slidably matched. In this way, when an external force acts on the frame assembly, the frame assembly rotates relative to the base 100 to drive the swing arm 200 and the connecting plate 300 to move.
[0035] Moreover, the frame assembly is provided with a first limiting structure 410, and the connecting plate 300 is provided with a second limiting structure 310. Optionally, the first limiting structure 410 and the second limiting structure 310 can both be limiting surfaces or limiting protrusions, and the embodiment of the present application does not specifically limit the first limiting structure 410 and the second limiting structure 310.
[0036] Figure 1 and Figure 2 The partial structure diagram and partial top view of the electronic device are shown respectively. Figure 4 for Figure 2 Cross-sectional view at BB, reference Figure 4 As shown, the electronic device has a folded state. When the electronic device is in the folded state, the frame assembly and the connecting plate 300 are limited in the first direction A through the first limiting structure 410 and the second limiting structure 310, and the connecting plate 300 is limited in the second direction B. The angle between the first direction A and the second direction B is less than 90°. Optionally, the first direction A and the second direction B may be parallel, that is, the direction of the limiting cooperation between the connecting plate 300 and the swing arm 200 is the same as the direction of the limiting cooperation between the frame assembly and the connecting plate 300; the first direction A and the second direction B may intersect, that is, the direction of the limiting cooperation between the connecting plate 300 and the swing arm 200 is different from the direction of the limiting cooperation between the frame assembly and the connecting plate 300.
[0037] Alternatively, if Figure 8 As shown, the connecting plate 300 is provided with a fifth limiting structure 320; Figure 6 and Figure 7 As shown, the swing arm 200 is provided with a sixth limiting structure 210, and when the electronic device is in a folded state, the connecting plate 300 and the swing arm 200 are limitedly positioned in the second direction B through the fifth limiting structure 320 and the sixth limiting structure 210. Further optionally, the fifth limiting structure 320 and the sixth limiting structure 210 may be limiting surfaces or limiting protrusions, and the embodiment of the present application does not specifically limit the fifth limiting structure 320 and the sixth limiting structure 210.
[0038] In the embodiment of the present application, when the electronic device is in a folded state, the first limiting structure 410 and the second limiting structure 310 are used to realize the limiting cooperation between the connecting plate 300 and the frame assembly in the first direction A. At the same time, the connecting plate 300 and the swing arm 200 are limited in the second direction B, and the angle between the first direction A and the second direction B is less than 90°, so that the swing arm 200, the connecting plate 300 and the frame assembly are stable in limiting cooperation in sequence, which is conducive to achieving relative fixation of the swing arm 200 and the frame assembly and avoiding sliding of the frame assembly relative to the swing arm 200. Then, when the electronic device in the folded state falls, the frame assembly will not slip relative to the swing arm 200, thereby avoiding squeezing the display screen of the electronic device, and further avoiding collision of the display screen with other components to damage the electronic device, which is conducive to improving the reliability of the electronic device when it falls.
[0039] In an optional embodiment, if Figure 4 As shown, the frame assembly includes a connected frame support 400 and a frame 500, the frame support 400 is used to support the frame 500, the frame 500 is located at the periphery of the frame support 400, and the frame support 400 and the frame 500 can be fixedly connected by bolt connection, welding, bonding, etc. The frame support 400 is slidably matched with the swing arm 200, and the first limiting structure 410 is provided on the frame support 400. Optionally, the frame support 400 and the swing arm 200 can be slidably matched by the matched first slide groove 430 and the slide rail 220, or can be slidably matched by the matched slider and guide rail.
[0040] In the present application, the frame support 400 and the frame 500 are further provided with a third limiting structure 420 and a fourth limiting structure 510, respectively. When the electronic device is in a folded state, the frame 500 and the frame support 400 are limited by the fourth limiting structure 510 and the third limiting structure 420. Specifically, the frame 500 and the frame support 400 are limited in the third direction C by the fourth limiting structure 510 and the third limiting structure 420. The third direction C can be parallel to the first direction A or the second direction B mentioned above, or can intersect with the first direction A and the second direction B. Optionally, the third limiting structure 420 and the fourth limiting structure 510 can be limiting surfaces or limiting protrusions. The embodiment of the present application does not specifically limit the third limiting structure 420 and the fourth limiting structure 510.
[0041] Since the connection area between the frame bracket 400 and the frame 500 is limited, and when the electronic device is in a folded state, the limiting effect of the frame bracket 400 and the frame 500 due to the connection structure is limited, the third limiting structure 420 and the fourth limiting structure 510 are separately provided for limiting cooperation, which is beneficial to the limiting cooperation of the frame 500 and the frame bracket 400 in the folded state, and realizes the limiting cooperation of the frame 500, the frame bracket 400, the connecting plate 300 and the swing arm 200 in sequence, thereby preventing the frame 500 and the frame bracket 400 from sliding relative to the swing arm 200, and further improving the reliability of the electronic device in the folded state.
[0042] In an optional embodiment, the angle between the third direction C and the first direction A is less than 90°, and the angle between the third direction C and the second direction B is less than 90°. Optionally, the angle between the third direction C and the first direction A is in the range of 30°-60°; the third direction C is parallel to the second direction B, that is, the angle between the third direction C and the second direction B is 0°, and of course, the angle between the third direction C and the second direction B can also be in the range of 30°-60°.
[0043] With this embodiment, the angles between any two of the first direction A, the second direction B and the third direction C are relatively small, so the directions in which the frame 500, the frame bracket 400, the connecting plate 300 and the swing arm 200 are sequentially limited and matched are relatively consistent, which is more conducive to the stable limiting and matching of the frame 500, the frame bracket 400, the connecting plate 300 and the swing arm 200 in sequence, and effectively avoids the frame bracket 400 from slipping relative to the swing arm 200 in the folded state, thereby avoiding squeezing the display screen of the electronic device, and improving the reliability of the electronic device when it falls.
[0044] Of course, in other embodiments, the angle between the third direction C and the first direction A or the second direction B may be greater than 90°.
[0045] In a further embodiment, reference Figure 4 As shown, at least one of the second direction B and the third direction C is perpendicular to the plane where the base 100 is located. That is, the fifth limiting structure 320 of the connecting plate 300 and the fourth limiting structure 510 of the frame 500 are both oriented toward the rotating shaft 110 of the base 100, and the first limiting structure 410 of the frame support 400 is oriented toward the side where the base 100 is located. Optionally, only the second direction B may be perpendicular to the plane where the base 100 is located, only the third direction C may be perpendicular to the plane where the base 100 is located, or both the second direction B and the third direction C may be perpendicular to the plane where the base 100 is located.
[0046] At least one of the second direction B and the third direction C is perpendicular to the plane where the base 100 is located, that is, when the electronic device is in the folded state, the frame bracket 400 and the connecting plate 300 can cooperate with the upper limit position in the direction toward the rotating shaft 110, and the connecting plate 300 and the swing arm 200 can cooperate with the upper limit position in the direction toward the rotating shaft 110. In this way, it can more effectively prevent the rotating shaft 110 of the base 100 from being squeezed when the electronic device falls, thereby affecting the display screen of the electronic device, which is beneficial to the reliability and stability of the electronic device in the folded state.
[0047] In the present application, the second direction B and the third direction C are parallel, both directions are perpendicular to the plane where the base 100 is located, and the first direction A intersects with the plane where the base 100 is located.
[0048] Of course, in other embodiments, both the second direction B and the second direction B may intersect with the plane where the base 100 is located but are not perpendicular to it.
[0049] In an optional embodiment, the connecting plate 300 only includes a main body 301 , and the second limiting structure 310 is disposed on the main body 301 , so that the frame support 400 and the main body 301 are limitedly matched in the first direction A.
[0050] In another embodiment, reference Figure 4 As shown, the connecting plate 300 includes a main body 301 and a protrusion 302, the protrusion 302 protrudes from the side of the main body 301 facing the frame support 400, the protrusion 302 is opposite to the frame support 400, and the protrusion 302 forms a second limiting structure 310, that is, the frame support 400 and the protrusion 302 are limited in the first direction A. Optionally, the protrusion 302 can be a square protrusion, a circular protrusion or other protrusion structures, and the embodiment of the present application does not limit the specific structure of the protrusion 302, and the position of the protrusion 302 and the frame support 400 can be in the form of surface contact or point contact.
[0051] Since the angle between the plane where the main body 301 of the connecting plate 300 is located and the plane where the swing arm 200 is located is small, if the frame bracket 400 and the main body 301 are limited in the first direction A, the angle deviation between the first direction A and the second direction B is large. Therefore, the protrusion 302 is provided to limit the frame bracket 400, so that the angle deviation between the first direction A and the second direction B of the frame bracket 400 and the protrusion 302 is small, that is, the angle between the first direction A and the second direction B is smaller, which is more conducive to the stable limit cooperation of the frame bracket 400, the connecting plate 300 and the swing arm 200 in sequence, thereby improving the reliability of the electronic device when it falls.
[0052] In an optional embodiment, when the electronic device is in a folded state, the frame support 400 and the connecting plate 300 are limited and matched only by the first limiting structure 410 and the second limiting structure 310. Optionally, the first direction A, the second direction B and the third direction C can be parallel to each other.
[0053] In another embodiment, reference Figure 4 As shown, the first limiting structure 410 cooperates with the main body 301 in limiting positioning in the fourth direction D, and the fourth direction D intersects with the first direction A. Optionally, the fourth direction D is perpendicular to the first direction A; moreover, the angle between the fourth direction D and the second direction B is less than 90°. Optionally, the fourth direction D can be parallel to the second direction B or intersect with the second direction B; the angle between the fourth direction D and the third direction C is less than 90°. Optionally, the fourth direction D can be parallel to the third direction C or intersect with the third direction C.
[0054] With this embodiment, in the folded state, the first limiting structure 410 is not only limited by the protrusion 302, but also limited by the main body 301. The directions of the limiting cooperation are increased, and the area of the limiting cooperation between the frame bracket 400 and the connecting plate 300 is increased, which is beneficial to improving the stability of the electronic device in the folded state and further avoiding relative sliding between the frame bracket 400 and the swing arm 200.
[0055] In a further embodiment, reference Figure 4 and Fig.12 As shown, the first limiting structure 410 includes a first limiting surface 411 and a second limiting surface 412 that intersect and connect with each other, the second limiting structure 310 is a third limiting surface, the main body 301 is provided with a fourth limiting surface 301a, the third limiting surface and the fourth limiting surface 301a intersect and connect with each other, and when the electronic device is in a folded state, the first limiting surface 411 cooperates with the third limiting surface for limiting in the first direction A, and the second limiting surface 412 cooperates with the fourth limiting surface 301a for limiting in the fourth direction D.
[0056] Optionally, the first limiting surface 411, the second limiting surface 412, the third limiting surface and the fourth limiting surface 301a are all limiting planes. When the electronic device is in a folded state, the first limiting surface 411 is in contact with the third limiting surface, and the second limiting surface 412 is in contact with the fourth limiting surface 301a. Of course, the first limiting surface 411, the second limiting surface 412, the third limiting surface and the fourth limiting surface 301a can also be limiting curved surfaces.
[0057] In this embodiment, each limiting structure is set in the form of a limiting surface, and the main body 301 is also provided with a fourth limiting surface 301a to achieve limiting cooperation. The limiting structure is simple, and there is no need to set each limiting structure into a complex structure such as a limiting protrusion. It can also ensure that the frame bracket 400 and the swing arm 200 are limited in different directions.
[0058] In this embodiment, if Figure 6 As shown, the length dimension a of the sixth limiting structure 210 of the swing arm 200 may be greater than 1.5 mm. Figure 7 As shown, the height dimension b of the sixth limiting structure 210 may be greater than 0.3 mm, and the height dimension refers to the dimension in the thickness direction of the swing arm 200; Figure 8 As shown, the length dimension c of the fifth limiting structure 320 of the connecting plate 300 may be greater than 3 mm. Fig.10 As shown, the length dimension d of the second limiting structure 310 of the connecting plate 300 may be greater than 3 mm, and the height dimension e may be greater than 0.6 mm, where the height dimension refers to the dimension in the thickness direction of the connecting plate 300; Fig.12 As shown, the thickness dimension g of the first limiting structure 410 of the frame support 400 may be greater than 0.6 mm, and the thickness dimension is the dimension of the first limiting structure 410 in the fourth direction D; Fig.14 As shown, the length dimension f of the first limiting structure 410 may be greater than 3 mm.
[0059] It should be noted that the “length dimensions” mentioned above all refer to the dimensions in the axial direction of the rotating shaft 110 .
[0060] In the solution of the present application, one of the swing arm 200 and the frame support 400 is provided with a first slide groove 430, and the other is provided with a slide rail 220, the slide rail 220 extends into the first slide groove 430, and the slide rail 220 and the first slide groove 430 are slidably matched, and the first limiting structure 410 is provided on the slide rail 220 or the first slide groove 430. Optionally, as Figure 5 As shown, the swing arm 200 is provided with a slide rail 220. Fig.13As shown, the frame support 400 is provided with a first slide groove 430 , and the first limiting structure 410 is arranged on the first slide groove 430 ; or, the swing arm 200 is provided with a first slide groove 430 , the frame support 400 is provided with a slide rail 220 , and the first limiting structure 410 is arranged on the slide rail 220 .
[0061] With this embodiment, the first limiting structure 410 is set at the position where the swing arm 200 and the frame bracket 400 are slidingly matched. Then, when the electronic device is in a folded state, the limiting effect of the position where the frame bracket 400 is slidingly matched is greater, and the frame bracket 400 and the swing arm 200 are less likely to have relative slippage, thereby avoiding squeezing the display screen of the electronic device, which is beneficial to further improve the reliability of the electronic device when it falls.
[0062] In an alternative embodiment, reference Figure 3 As shown, one of the connecting plate 300 and the swing arm 200 is provided with a second slide groove 330, and the other is provided with a cylindrical protrusion 230. The cylindrical protrusion 230 extends into the second slide groove 330. During the folding process of the electronic device, the cylindrical protrusion 230 slides along the second slide groove 330 and rotates relative to the second slide groove 330. Optionally, the cylindrical protrusion 230 can be a cylindrical structure to facilitate the rotation of the cylindrical protrusion 230 relative to the second slide groove 330. Of course, the cylindrical protrusion 230 can also be a square column structure. Optionally, as Fig. 9 As shown, the connecting plate 300 is provided with a second slide groove 330; Figure 5-Figure 7 As shown, the swing arm 200 is provided with a cylindrical protrusion 230 ; or, the connecting plate 300 is provided with a cylindrical protrusion 230 , and the swing arm 200 is provided with a second sliding groove 330 .
[0063] In this embodiment, by providing the second slide groove 330 and the cylindrical protrusion 230, the connecting plate 300 and the swing arm 200 are movably connected, and the two can move and rotate relative to each other, while avoiding direct separation of the two.
[0064] In an alternative embodiment, reference Figure 3 As shown, the second slide groove 330 is provided with an avoidance groove 331. When the electronic device is in a folded state, the cylindrical protrusion 230 is located at one end of the second slide groove 330, and the cylindrical protrusion 230 can extend into the avoidance groove 331. Optionally, the avoidance groove 331 can be a square groove or an arc groove. The embodiment of the present application does not limit the shape of the avoidance groove 331, as long as it can allow the cylindrical protrusion 230 to extend. In the present application, the second slide groove 330 is provided on the connecting plate 300, the cylindrical protrusion 230 is provided on the swing arm 200, and the avoidance groove 331 is located on one side of the second slide groove 330 close to the position where the frame bracket 400 and the connecting plate 300 are limited and matched.
[0065] By adopting this embodiment, by setting the avoidance groove 331, in the folded state, when the electronic device falls, the cylindrical protrusion 230 can extend into the avoidance groove 331, so as to prevent the cylindrical protrusion 230 from directly squeezing the groove wall surface of the second slide groove 330, that is, to prevent the swing arm 200 and the connecting plate 300 from squeezing each other, causing the connecting plate 300 and the swing arm 200 to directly disengage from the limiting cooperation, thereby ensuring the limiting stability in the folded state.
[0066] Of course, in other embodiments, the second slide groove 330 may not be provided with the avoidance groove 331, and the width of the second slide groove 330 may be set larger, so that the width of the second slide groove 330 is greater than the width of the cylindrical protrusion 230, thereby avoiding the second slide groove 330 and the cylindrical protrusion 230 from squeezing each other.
[0067] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
