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 pursuit of a better visual experience, the display screens of electronic devices are getting larger and larger, which leads to a significant reduction in the portability and comfort of electronic devices.

[0003] In the related art, a foldable electronic device relies on a hinge mechanism to achieve folding and unfolding, and the hinge mechanism includes a base, a first swing arm, a second swing arm, and a connecting member, wherein the first swing arm and the second swing arm are respectively located on the same side of the base, and the first swing arm and the second swing arm are respectively rotatably connected to the base, the rotation axis of the first swing arm is different from the rotation axis of the second swing arm, the connecting member is rotatably connected to the first swing arm, and the connecting member is slidably matched with the second swing arm, and at the same time, the first swing arm and the second swing arm are movably connected, so that the first swing arm and the second swing arm can rotate and slide relative to each other. Moreover, the connecting member is connected to the frame of the foldable electronic device, and when the frame drives the connecting member to move, the connecting member drives the first swing arm and the second swing arm to rotate relative to the base.

[0004] In order to achieve the thinness and lightness of electronic devices, the hinge mechanism occupies less space in the thickness direction of the electronic device, resulting in a smaller gap between the part where the first swing arm and the second swing arm are movably connected and the frame when the electronic device is folded. As a result, when the electronic device falls, the frame collides with the first swing arm, making the frame easily deformed, which in turn causes problems such as abnormal noise and shaking, and the drop reliability of the electronic device is poor. Therefore, existing foldable electronic devices cannot take into account both the thinness and drop reliability. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem in the related art that foldable electronic devices cannot take into account both lightness and thinness as well as drop reliability.

[0006] An embodiment of the present application provides an electronic device, including a hinge mechanism, a frame, and an elastic deformation sheet, wherein the hinge mechanism includes a base, a first swing arm, a second swing arm, and a connecting piece, wherein the first swing arm and the second swing arm are both located on the same side of the base, the first swing arm and the second swing arm are respectively rotatably connected to the base, and the connecting piece is rotatably connected to the first swing arm, and the connecting piece is slidably connected to the second swing arm. The first swing arm comprises a matching portion, the matching portion is provided with a slide groove, the second swing arm is provided with a protrusion, the protrusion extends into the slide groove, and the protrusion can slide and rotate relative to the slide groove, The frame is connected to the connecting member, and the frame is provided with an avoidance hole, the avoidance hole is opposite to the matching portion, the elastic deformation sheet is located on the side of the avoidance hole away from the hinge mechanism, and the elastic deformation sheet is connected to the frame to close the avoidance hole. When the electronic device is in a falling state, the matching portion can extend into the avoidance hole and contact with the elastic deformation sheet.

[0007] In the embodiment of the present application, an avoidance hole is provided at the position of the matching part of the first swing arm corresponding to the frame of the electronic device, and an elastic deformation sheet is added, and the avoidance hole is closed by the elastic deformation sheet. In this way, when the electronic device is in a folded state, if the electronic device falls, the matching part can be extended into the avoidance hole, and the gap between the elastic deformation sheet and the matching part is reduced, and even the elastic deformation sheet and the matching part are in contact or collided. Since the matching part is opposite to the elastic deformation sheet, the matching part will only collide with the elastic deformation sheet, and will not directly collide with the frame, and the elastic deformation sheet will produce elastic deformation. After the falling process is completed, the elastic deformation sheet restores the elastic deformation, avoiding the frame from being directly collided and causing permanent deformation, thereby avoiding problems such as scratching, abnormal noise, and shaking between the frame and the matching part, which is conducive to improving the reliability of falling. Moreover, there is no need to increase the gap between the frame and the matching part to avoid collision between the two. The gap between the matching part and the elastic deformation sheet can be set to be smaller, which is conducive to reducing the thickness of the hinge mechanism and realizing the thinness of the electronic device.

[0008] Therefore, the electronic device in the embodiment of the present application can achieve both lightness and thinness and improve drop reliability. BRIEF DESCRIPTION OF THE DRAWINGS

Of course, the rotational connection between the base 110 and the first swing arm 120 and between the base 110 and the second swing arm 130 can also be realized by other methods.

[0017] Moreover, the connecting member 140 is rotatably connected to the first swing arm 120. Optionally, the connecting member 140 and the first swing arm 120 can be rotatably connected by a hinge structure, or one of the connecting member 140 and the first swing arm 120 is provided with a cylindrical protrusion, and the other is provided with a cylindrical groove, the cylindrical protrusion extends into the cylindrical groove, and the cylindrical protrusion and the cylindrical groove are rotatably matched to realize the rotatable connection between the connecting member 140 and the first swing arm 120; the connecting member 140 is slidably connected to the second swing arm 130, optionally, refer to Figure 2 As shown, one of the connecting member 140 and the second swing arm 130 is provided with a slide plate 132, and the other is provided with a slide rail 141. The slide rail 141 is provided with a slot, and the slide plate 132 can extend into the slot of the slide rail 141, and the slide rail 141 and the slide plate 132 are slidably matched to realize the sliding connection between the connecting member 140 and the second swing arm 130. Of course, the connecting member 140 and the second swing arm 130 can also be rotatably connected by other methods.

[0018] The first swing arm 120 and the second swing arm 130 can slide and rotate relative to each other. Figure 3 In the cross-sectional view shown, the first swing arm 120 includes a matching portion 121, the matching portion 121 is provided with a slide groove 121a, and the second swing arm 130 is provided with a protrusion 131, the protrusion 131 extends into the slide groove 121a, and the protrusion 131 can slide and rotate relative to the slide groove 121a. Optionally, the matching portion 121 can be an annular structure, the matching portion 121 surrounds to form the slide groove 121a, and the protrusion 131 can be a cylindrical structure, which is conducive to the smooth rotation of the protrusion 131 relative to the slide groove 121a. Of course, the protrusion 131 can also be a square columnar structure or a protrusion structure of other shapes. In this way, the first swing arm 120 and the second swing arm 130 can slide and rotate relative to each other through the slide groove 121a and the protrusion 131 of the matching portion 121.

[0019] The frame 200 is connected to the connector 140. Optionally, the frame 200 and the connector 140 can be connected by welding, bonding, etc. Moreover, the frame 200 is provided with an avoidance hole 210. The avoidance hole 210 is opposite to the matching portion 121. The avoidance hole 210 can be a square structure, a circular structure, etc. The embodiment of the present application does not limit the specific shape of the avoidance hole 210. When the electronic device is in a falling state, the matching portion 121 can extend into the avoidance hole 210. In this way, the avoidance hole 210 is set at the position of the frame 200 corresponding to the matching portion 121, and the matching portion 121 is avoided to avoid direct collision between the frame 200 and the matching portion 121.

[0020] The elastic deformation sheet 300 is located on the side of the avoidance hole 210 away from the hinge mechanism 100, that is, the elastic deformation sheet 300 is located on the side of the frame 200 away from the matching portion 121. Moreover, the elastic deformation sheet 300 is connected to the frame 200 to close the avoidance hole 210. Optionally, the edge of the elastic deformation sheet 300 can be connected to the frame 200 by welding, bonding, etc.; the elastic deformation sheet 300 can be a silicone sheet, or a TPU (thermoplastic polyurethane elastomer rubber, Thermoplasticpolyurethanes) sheet, of course, it can also be other sheet structures that can produce elastic deformation; the elastic deformation sheet 300 can be a square structure, a circular structure, etc., and the embodiment of the present application does not limit the shape of the elastic deformation sheet 300, and the elastic deformation sheet 300 can close the avoidance hole 210. In this way, the avoidance hole 210 is closed by the elastic deformation sheet 300 to avoid the avoidance hole 210 from being directly exposed, and at the same time, it is conducive to meeting the waterproof requirements of the frame 200.

[0021] The electronic device has a folded state and an unfolded state. When the electronic device falls, the electronic device is in the folded state. When the electronic device is in the fallen state, the matching portion 121 can extend into the avoidance hole 210 and contact the elastic deformation sheet 300.

[0022] In the embodiment of the present application, an avoidance hole 210 is opened at a position of the matching portion 121 of the first swing arm 120 of the frame 200 of the electronic device, and an elastic deformation sheet 300 is additionally provided, and the avoidance hole 210 is closed by the elastic deformation sheet 300. In this way, when the electronic device is in a folded state, if the electronic device falls, the matching portion 121 can extend into the avoidance hole 210, and the gap between the elastic deformation sheet 300 and the matching portion 121 is reduced, and even the elastic deformation sheet 300 contacts or collides with the matching portion 121. Since the matching portion 121 is opposite to the elastic deformation sheet 300, the matching portion 121 will only collide with the elastic deformation sheet 300, and will not directly collide with the frame 200. The elastic deformation sheet 300 generates elastic deformation. After the falling process is completed, the elastic deformation sheet 300 restores the elastic deformation, thereby avoiding the frame 200 from being directly collided and permanently deformed, thereby avoiding problems such as scratching, abnormal noise, and shaking between the frame 200 and the matching portion 121, which is beneficial to improving the falling reliability. Furthermore, there is no need to increase the gap between the frame 200 and the mating portion 121 to avoid collision between the two. The gap between the mating portion 121 and the elastic deformation sheet 300 can be set smaller, which is beneficial to reducing the thickness of the hinge mechanism 100 and achieving lightweight electronic equipment.

[0023] Therefore, the electronic device in the embodiment of the present application can achieve both lightness and thinness and improve drop reliability.

[0024] In an optional embodiment, the electronic device has an unfolded state and a folded state, and when the electronic device is in the unfolded state, the matching portion 121 is located outside the avoidance hole 210; when the electronic device is in the folded state, the matching portion 121 does not extend into the avoidance hole 210. That is, the matching portion 121 will extend into the avoidance hole 210 only when the electronic device falls.

[0025] In another embodiment, reference Figure 3 As shown, when the electronic device is in the folded state, the matching portion 121 extends into the avoidance hole 210, and specifically, a portion of the matching portion 121 extends into the avoidance hole 210. That is, when the electronic device is in the folded state, the matching portion 121 will extend into the avoidance hole 210 regardless of whether the electronic device falls or not.

[0026] With this embodiment, the structure of the avoidance hole 210 not only prevents the mating portion 121 from directly colliding with the frame 200 in a falling state, but also allows the mating portion 121 to extend into the folded state to reduce the thickness of the hinge mechanism 100, which is beneficial to further reduce the thickness of the electronic device in the folded state, thereby achieving a thin and lightweight electronic device.

[0027] In the scheme of this application, reference is made to Figure 3As shown, the elastic deformation sheet 300 includes a connecting portion 330, a bending portion 320 and a deformation portion 310 connected in sequence, the bending portion 320 is arranged around the deformation portion 310, and the bending portion 320 is a ring-shaped bending structure; the connecting portion 330 is arranged around the bending portion 320, that is, the connecting portion 330 is a ring-shaped structure, and the connecting portion 330 is used to connect the frame 200, the connecting portion 330 is connected to the frame 200, and the connecting portion 330 and the frame 200 can be connected by welding, bonding, etc. Optionally, the connecting portion 330, the bending portion 320 and the deformation portion 310 can be an integrated structure or a split structure.

[0028] Specifically, when the elastic deformation sheet 300 is subjected to force, the bending portion 320 generates elastic deformation, the bending portion 320 unfolds and drives the deformation portion 310 to move relative to the frame 200; when the force exerted on the elastic deformation sheet 300 disappears, the bending portion 320 restores the elastic deformation and drives the deformation portion 310 to return to its original position.

[0029] In this embodiment, the bending portion 320 serves as a connecting bridge between the deformation portion 310 and the connecting portion 330. When the deformation portion 310 is subjected to force, the bending portion 320 adapts to the force change at the edge of the deformation portion 310, so that the deformation portion 310 moves directly, avoiding the connection portion 330 being subjected to force and affecting the connection between the connection portion 330 and the frame 200, ensuring that the elastic deformation sheet 300 is stably connected to the frame 200, and avoiding the connection portion 330 being separated from the frame 200 and affecting the waterproof performance of the electronic device. Of course, in other embodiments, the elastic deformation sheet 300 may not include the bending portion 320 , that is, the connecting portion 330 is directly connected to the deformation portion 310 , and when the deformation portion 310 is subjected to force, the deformation portion 310 generates elastic deformation.

[0030] In a further embodiment, reference Figure 3 As shown, the bending portion 320 includes an arc portion 321, which is arranged around the deformation portion 310, and the arc portion 321 has an inner edge and an outer edge, the inner edge is smoothly connected to the deformation portion 310, and the outer edge is smoothly connected to the connecting portion 330. Optionally, the number of the arc portion 321 can be one; or the number of the arc portion 321 is multiple, each arc portion 321 is arranged in sequence, each arc portion 321 is smoothly connected in sequence, and the inner edge of the arc portion 321 located on the inner side is smoothly connected to the deformation portion 310, and the outer edge of the arc portion 321 located on the outer side is smoothly connected to the connecting portion 330. Further optionally, the connecting portion 330, each arc portion 321 and the deformation portion 310 are connected in sequence to form an integrated structure.

[0031] In this embodiment, the bending portion 320 adopts an arc structure, and the arc portion 321 does not have any sharp connection, thereby avoiding stress concentration and preventing the bending portion 320 from frequent elastic deformation and fracture, which is beneficial to improving the fatigue resistance of the bending portion 320.

[0032] In this embodiment, there are two arc-shaped portions 321. Of course, the arc-shaped portions 321 may also be provided in other numbers.

[0033] In an alternative embodiment, reference Figure 3 As shown, the electronic device further includes an anti-wear sheet 400, which is located on the side of the deformation portion 310 facing the matching portion 121, and the anti-wear sheet 400 is in contact with the deformation portion 310. Optionally, the anti-wear sheet 400 and the deformation portion 310 can be connected by welding, bonding, etc. The anti-wear sheet 400 can be a steel sheet, copper foil, plastic sheet, etc., and the material of the plastic sheet can be PET (polyethylene terephthalate). When the electronic device is in a falling state, the matching portion 121 extends into the avoidance hole 210 and contacts the deformation portion 310 through the anti-wear sheet 400.

[0034] With this embodiment, when the mating portion 121 extends into the avoidance hole 210, the mating portion 121 may contact the anti-wear sheet 400, and then act on the deformation portion 310 through the anti-wear sheet 400, thereby preventing the mating portion 121 from directly contacting the deformation portion 310 and scratching the elastic deformation sheet 300, thereby improving the wear resistance of the elastic deformation sheet 300 and helping to extend the life of the elastic deformation sheet 300.

[0035] Of course, in other embodiments, the electronic device may not be provided with the anti-wear sheet 400 . When the electronic device is in a falling state, the matching portion 121 extends into the avoidance hole 210 and directly contacts the deformation portion 310 .

[0036] In an optional embodiment, the electronic device further includes a sealing connector 500 , which is located between the connecting portion 330 and the frame 200 , and is sealedly connected to the connecting portion 330 and the frame 200 , respectively.

[0037] Optionally, the sealing connector 500 may be a connecting glue, which may be a double-sided tape or glue, and the glue may be evenly disposed between the connecting portion 330 and the frame 200 by dispensing, and the connecting portion 330 and the frame 200 are directly and sealably connected by the connecting glue, that is, the sealing connector 500 is directly and sealably connected to the connecting portion 330 and the frame 200, and there is no need to perform separate connection operations between the sealing connector 500 and the connecting portion 330, and between the sealing connector 500 and the frame 200. Further, optionally, in the width direction of the connecting portion 330, the size of the connecting glue is 1 mm to prevent the avoidance hole 210 from entering liquid or dust due to a small width of the connecting glue; or, the sealing connector 500 may be other components that have a sealing effect, and then the sealing connector 500 is respectively and sealably connected to the connecting portion 330 and the frame 200 by dispensing or the like.

[0038] In this embodiment, the connection part 330 and the frame 200 are sealed by the sealing connector 500, which is beneficial to seal the gap between the connection part 330 and the frame 200 to seal the avoidance hole 210, which is beneficial to improve the waterproof and dustproof performance of the electronic device.

[0039] In an optional embodiment, the sealing connector 500 may be a block structure.

[0040] In another embodiment, the sealing connector 500 is a strip-shaped structure, and the sealing connector 500 extends along the extending direction of the connecting portion 330. Optionally, the sealing connector 500 may be an annular structure, and the sealing connector 500 surrounds the edge of the avoidance hole 210.

[0041] With this embodiment, the length of the sealing connector 500 increases in the direction in which the connecting portion 330 extends, and the area of ​​the sealing connector 500 for sealing connection also increases, which is more conducive to further sealing the gap between the connecting portion 330 and the frame 200, and further improving the waterproof and dustproof performance of the electronic device.

[0042] It should be noted that there is a certain distance between the sealing connector 500 and the anti-wear sheet 400 to ensure that the bending portion 320 can smoothly produce elastic deformation. Optionally, the distance between the sealing connector 500 and the anti-wear sheet 400 is greater than 1 mm.

[0043] In the solution of the present application, the electronic device further includes a pressure pad 600 and a cover 700. Figure 3As shown, the pressure pad 600 is located on the side of the connection part 330 facing away from the matching part 121. Optionally, the pressure pad 600 and the connection part 330 can be fixedly connected by welding, bonding, etc.; the cover body 700 can be a battery cover, or it can be other covers 700 other than the battery cover. The cover body 700 is located on the side of the pressure pad 600 facing away from the connection part 330, and the cover body 700 is connected to the frame body 200. Optionally, the cover body 700 and the frame body 200 are fixedly connected by welding, bonding, etc. The cover body 700 acts on the connection part 330 through the pressure pad 600. The cover body 700 can act on the pressure pad 600 directly or indirectly through other components. In short, it is sufficient to apply a force to the connection part 330 through the pressure pad 600.

[0044] Optionally, the pressure pad 600 is used to press the connection part 330. The pressure pad 600 can be a soft pad that can produce a certain degree of deformation to prevent the cover body 700 from applying a large force to the connection part 330. The material of the soft pad can be PVC (polyvinyl chloride) or PU (polyurethane), of course, it can also be other materials.

[0045] With this embodiment, when the cover body 700 is installed to the frame body 200, the cover body 700 will act on the connecting part 330 through the pressure pad 600, so that the connecting part 330 acts on the frame body 200, which is beneficial for the connecting part 330 and the frame body 200 to be more tightly connected, avoiding the generation of a gap between the connecting part 330 and the frame body 200, ensuring the sealing performance of the electronic device, and being beneficial for further improving the waterproof and dustproof performance of the electronic device.

[0046] Optionally, the cover body 700 acts on the connection part 330 through the pressure pad 600 so that the connection part 330 squeezes the sealing connector 500. Further optionally, the connection part 330 squeezes the connecting glue, which is conducive to a tighter sealing connection between the connection part 330 and the frame 200 through the connecting glue to prevent the connecting glue from breaking.

[0047] Of course, in other embodiments, the electronic device may not be provided with the pressure pad 600 , that is, there is a gap between the cover 700 and the connecting portion 330 , and when the cover 700 is installed to the frame 200 , the cover 700 does not apply force to the connecting portion 330 .

[0048] In an optional embodiment, the pressure pad 600 may be a block structure.

[0049] In another embodiment, the pressure pad 600 is a strip-shaped structure, and the pressure pad 600 extends along the extending direction of the connecting portion 330. Alternatively, the pressure pad 600 may be a ring-shaped structure, and the pressure pad 600 is disposed around the bending portion 320.

[0050] With this embodiment, in the direction in which the connection part 330 extends, the extension length of the pressure pad 600 increases, and the action area of ​​the cover body 700 on the connection part 330 through the pressure pad 600 increases. Then, the action area of ​​the connection part 330 on the frame body 200 also increases, thereby increasing the area in which the connection part 330 and the frame body 200 are tightly connected, and more effectively avoiding the generation of a gap between the connection part 330 and the frame body 200, further improving the sealing performance of the electronic device, and further improving the waterproof and dustproof performance of the electronic device.

[0051] In an alternative embodiment, reference Figure 3 As shown, the mating portion 121 is provided with a contact surface 121b, which is a plane. The contact surface 121b is opposite to the elastic deformation sheet 300, and the mating portion 121 contacts the elastic deformation sheet 300 through the contact surface 121b. The electronic device has an unfolded state and a folded state. When the electronic device is in the unfolded state, the contact surface 121b intersects with the plane where the elastic deformation sheet 300 is located; when the electronic device is in the folded state, the contact surface 121b is parallel to the plane where the elastic deformation sheet 300 is located, and when the electronic device is in a dropped state, the contact surface 121b contacts the elastic deformation sheet 300.

[0052] In this embodiment, the contact surface 121b of the mating portion 121 is a plane. Since the contact surface 121b is parallel to the plane where the elastic deformation sheet 300 is located in the folded state, if the electronic device falls, the contact surface 121b is in full contact with the elastic deformation sheet 300, and the contact area between the mating portion 121 and the elastic deformation sheet 300 is increased, which is beneficial to reducing the friction between the mating portion 121 and the elastic deformation sheet 300, and at the same time helps to reduce the collision force between the two.

[0053] Of course, in other embodiments, the contact surface 121 b may be a curved surface. When the electronic device is in a folded state, the contact surface 121 b is not parallel to the plane where the elastic deformation sheet 300 is located.
