DETAILED DESCRIPTION

[0028] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0029] Refer to the following Figures 1 to 16 An electronic device 400 according to some embodiments of the present application is described.

[0030] According to some embodiments of the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an electronic device 400 is provided, including a frame assembly 100 and a hinge assembly 200, wherein the frame assembly 100 is rotatably connected via the hinge assembly 200 so that the electronic device 400 can be switched between an unfolded state and a folded state; the hinge assembly 200 includes a first bracket 202 and a hinge cover 206, wherein the hinge cover 206 is disposed on one side of the first bracket 202, and a first mounting groove 302 is disposed on a side of the frame assembly 100 facing the hinge cover 206, wherein a ball assembly 500 is disposed in the first mounting groove 302, and the ball assembly 500 is in contact with the hinge cover 206; during the rotation of the frame assembly 100 relative to the hinge assembly 200, the ball assembly 500 rolls on the surface of the hinge cover 206.

[0031] In this technical solution, the electronic device 400 includes a frame assembly 100 and a hinge assembly 200. The frame assembly 100 is rotatably connected through the hinge assembly 200, so that the electronic device 400 can be switched between an unfolded state and a folded state, thereby realizing the unfolding or folding function of the electronic device 400. The strength of the first bracket 202 is used to support the rotating component 204, and the hinge cover 206 is covered on one side of the first bracket 202, so that the overall sealing of the electronic device 400 is stronger and dust is not easy to enter. A first mounting groove 302 is provided on the frame 300, and the opening of the first mounting groove 302 faces the hinge cover 206. A ball assembly 500 is provided in the first mounting groove 302 and protrudes from the first mounting groove 302. When the frame assembly 100 rotates relative to the hinge assembly 200, the ball assembly 500 rolls on the surface of the hinge cover 206. The deformation of the frame assembly 100 is resisted by the ball assembly 500 between the frame assembly 100 and the hinge cover 206, thereby reducing the contact between the surface of the frame assembly 100 and the hinge cover 206, thereby alleviating the jamming feeling when the electronic device 400 is opened and closed. Even if the frame assembly 100 is deformed, the frame assembly 100 will contact the cover surface of the hinge cover 206 through the ball assembly 500. During the unfolding or folding process of the electronic device 400, the sliding friction between the hinge cover 206 and the frame assembly 100 is converted into rolling friction, thereby reducing the friction force exerted on the frame assembly 100 during the unfolding or folding process, making the unfolding or folding of the electronic device 400 smoother, avoiding the problem of rotation jamming, and extending the service life of the electronic device 400.

[0032] At the same time, by setting the ball assembly 500 between the hinge cover 206 and the frame assembly 100, the deformation of the frame assembly 100 is alleviated, the overall strength of the electronic device 400 when it falls is ensured, and the reliability of the risk of falling of the electronic device 400 is improved.

[0033] The frame assembly 100 contacts the cover surface of the hinge cover 206 through the ball assembly 500. The ball assembly 500 guides the frame assembly 100 during the opening and closing process of the electronic device 400, thereby reducing the probability of the electronic device 400 being unable to open and close due to excessive deformation of the frame assembly 100, and improving the stability of the electronic device 400 after falling or being impacted.

[0034] The frame assembly 100 is in contact with the cover surface of the hinge cover 206 through the ball assembly 500, which can reduce the deformation of the frame assembly 100 after the frame assembly 100 of the electronic device 400 is impacted, thereby reducing the impact on the screen assembly 402 caused by the deformation of the frame assembly 100, so that the degree to which the frame assembly 100 squeezes the screen assembly 402 is reduced, thereby reducing the probability of damage to the screen assembly 402 after the electronic device 400 falls or is impacted, and further improving the stability of the electronic device 400 after it falls or is impacted.

[0035] The frame assembly 100 contacts the cover surface of the hinge cover 206 through the ball assembly 500. When the frame assembly 100 of the electronic device 400 is impacted, the deformation of the frame assembly 100 is reduced without increasing the thickness and volume of the frame assembly 100. This reduces the impact of adding the ball assembly 500 on the overall size of the electronic device 400, and is beneficial to the lightweight design of the electronic device 400.

[0036] The frame assembly 100 contacts the cover surface of the hinge cover 206 through the ball assembly 500, thereby reducing the friction between the frame assembly 100 and the hinge cover 206, reducing the wear and tear of the hinge cover 206 and the frame assembly 100 due to friction, and further reducing the probability of damage to the hinge cover 206 and the frame assembly 100 due to friction, thereby extending the service life of the electronic device 400 and further improving the stability of the electronic device 400 during use.

[0037] The frame assembly 100 contacts the cover surface of the hinge cover 206 through the ball assembly 500, thereby reducing the friction between the frame assembly 100 and the hinge cover 206, and also reducing the noise generated by the friction between the hinge cover 206 and the frame assembly 100, thereby reducing the probability of noise occurring during the unfolding or folding process of the electronic device 400, further improving the user experience of the electronic device 400.

[0038] Specifically, when the folding screen falls in the end direction, the end face of the frame assembly 100 is deformed by force, thereby reducing the first gap 210 between the frame assembly 100 and the hinge cover 206, resulting in zero-matching interference contact. The more serious the deformation of the frame assembly 100, the greater the force of squeezing the end face of the hinge cover 206, and the greater the friction, resulting in a jammed opening and closing, or even inability to open. If the above scheme is adopted, the frame assembly 100 is provided with a first installation groove 302 corresponding to the projection area of ​​the end face of the hinge cover 206, and the ball assembly 500 is installed therein and partially protrudes, so that there is a gap between the end face of the frame assembly 100 and the hinge cover 206. In this way, when the folding screen falls in the end direction, even if the frame assembly 100 of the folding screen is deformed to a certain extent, the frame assembly 100 will contact the hinge cover 206 through the ball assembly 500, reducing the friction between the frame assembly 100 and the hinge cover 206 when the electronic device 400 is opened and closed, thereby reducing the sluggish feeling when the electronic device 400 is opened and closed. At the same time, when the material of the ball assembly 500 is set to a high-strength material such as hard steel, the deformation of the frame assembly 100 is alleviated, the overall strength of the structure is improved, and the reliability of the electronic device 400 against the risk of falling is improved.

[0039] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the hinge assembly 200 includes at least two rotating parts 204, and the at least two rotating parts 204 are connected to the first bracket 202; the frame assembly 100 includes at least two frames 300, and the at least two frames 300 are respectively connected to the at least two rotating parts 204, and can be rotated relative to the first bracket 202 so that the electronic device 400 can switch between the unfolded state and the folded state; the first mounting groove 302 is set in the frame 300, and when the electronic device 400 is in the folded state, the opening of one side of the first mounting groove 302 faces the hinge cover 206.

[0040] In this embodiment, the hinge assembly 200 includes at least two rotating parts 204, and the at least two rotating parts 204 are connected to the first bracket 202, and the strength of the first bracket 202 is used to support the rotating parts 204. At least two frames 300 are respectively connected to the at least two rotating parts 204, and the frame assembly 100 is driven to unfold or fold by the rotation of the rotating parts 204, so as to realize the function of unfolding or folding the electronic device 400. A first mounting groove 302 is provided in the frame assembly 100, and when the device is in a folded state, the mounting hole opening faces the hinge cover 206, and a rolling part is provided in the mounting hole, and the mounting hole protrudes, so that there is a certain gap between the frame 300 and the hinge cover 206. When the device falls, the deformation of the frame 300 is resisted by the rolling part between the frame 300 and the hinge cover 206, and the contact between the frame assembly 100 and the cover surface of the hinge cover 206 is reduced, so as to alleviate the feeling of jamming when the device is opened and closed, thereby extending the service life of the electronic device 400 and reducing the impact on the user experience.

[0041] According to some embodiments of the present application, Figure 2 , Figure 3 and Figure 4 As shown, the ball assembly 500 includes a ball, at least a portion of the ball is located in the first mounting groove 302, and the ball is in contact with the hinge cover 206.

[0042] In this embodiment, the ball assembly 500 includes balls, at least part of which is located in the first mounting groove 302, and the balls are in contact with the hinge cover 206. When the frame 300 is deformed, the frame 300 will contact the cover surface of the hinge cover 206 through the balls. During the unfolding or folding of the electronic device 400, the sliding friction between the hinge cover 206 and the cover body is converted into rolling friction, thereby reducing the friction force exerted on the frame 300 during the unfolding or folding process, making the unfolding or folding of the electronic device 400 smoother, extending the service life of the electronic device 400 while reducing the impact on the customer's usage experience.

[0043] According to some embodiments of the present application, Figure 3 As shown, optionally, the ball assembly further includes a second bracket 304 , which is disposed in the first mounting groove 302 , connected to the frame 300 , and located on a side of the ball 208 away from the opening 326 .

[0044] In this embodiment, a second bracket 304 is disposed in the first mounting groove 302 and is connected to the frame 300. The second bracket 304 can more effectively support the ball 208. When the frame 300 encounters extrusion and collision, the risk of the ball 208 falling off is reduced, thereby enhancing the overall strength of the structural parts of the electronic device 400, thereby improving the reliability of the risk of the electronic device 400 falling.

[0045] According to some embodiments of the present application, Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, optionally, the second bracket 304 has an oil storage chamber 306 and an oil overflow hole 308. The oil storage chamber 306 can store lubricating oil. The oil overflow hole 308 is located on a side of the oil storage chamber 306 close to the ball 208. The oil overflow hole 308 is connected to the oil storage chamber 306 and extends toward the ball 208.

[0046] In this embodiment, the second bracket 304 is provided with an oil storage chamber 306 and an oil overflow hole 308. The oil storage chamber 306 is used to store lubricating oil, and the oil overflow hole 308 is used to convey the lubricating oil to the ball 208, thereby improving the smoothness of the rolling of the ball 208 in the first mounting groove 302. When the frame 300 is severely deformed, the ball 208 is squeezed to the hinge cover 206. Under the action of the lubricating oil, the friction between the ball 208 and the end surface of the hinge cover 206 can be reduced to a certain extent, and the friction between the ball 208 and the contact surface of the second bracket 304 can also be reduced, thereby improving the problem of the electronic device 400 being stuck when opening and closing after falling.

[0047] Specifically, the second bracket 304 for fixing the ball is provided with an oil storage groove and a plurality of tiny oil overflow holes 308 on the ball mating surface, which are sealed by a sealing cover 310 after storing oil. When the ball rotates, the lubricating oil in the oil overflow hole 308 can be brought out, and the lubricating oil covers the surface of the ball to play a lubricating role, thereby reducing the problem of the electronic device 400 being stuck when opening and closing.

[0048] Specifically, there are multiple overflow holes 308 , which are arranged in parallel, for example, in an annular arrangement, or in a torque arrangement. The multiple overflow holes 308 can all deliver the oil in the oil storage cavity 306 to the ball 208 .

[0049] According to some embodiments of the present application, Fig.11 As shown, optionally, the frame assembly 100 further includes a sealing cover 310 , which is disposed on a side of the oil storage cavity 306 away from the ball 208 and can open or close the oil storage cavity 306 .

[0050] In this embodiment, the oil storage chamber 306 is provided with a sealing cover 310, which plays the role of opening or closing the oil storage chamber 306. When the oil storage chamber 306 lacks lubricating oil, the sealing cover 310 can be opened to replenish the lubricating oil; when the lubricating oil in the oil storage chamber 306 is sufficient, the oil storage chamber 306 is sealed, the performance of oil lubrication is ensured, and the ball 208 is lubricated.

[0051] Furthermore, the sealing cover 310 is detachably disposed on a side of the oil storage chamber 306 away from the ball 208 .

[0052] The sealing cover 310 can be fixed to the side of the oil storage chamber 306 away from the ball 208 by process fitting.

[0053] The sealing cover 310 can also be fixed to the side of the oil storage chamber 306 away from the ball 208 by means of threads.

[0054] The sealing cover 310 can also be fixed to a side of the oil storage chamber 306 away from the ball 208 by snapping.

[0055] According to some embodiments of the present application, Fig.12 As shown, optionally, the frame 300 is provided with a positioning portion 312, which is located on the side of the first mounting groove 302 close to the hinge cover 206 and extends from the edge of the first mounting groove 302 to the middle of the first mounting groove 302; the ball 208 abuts against the side of the positioning portion 312 away from the hinge cover 206.

[0056] In this embodiment, a positioning portion 312 is provided on the frame 300, and the positioning portion 312 is used to limit the rolling component to prevent the ball 208 from being separated from the first mounting groove 302. When the frame 300 of the electronic device 400 encounters an extrusion collision, one side of the ball 208 abuts against the second bracket 304, and the other side abuts against the positioning portion 312, so that the ball 208 is limited in the first mounting groove 302, reducing the risk of the ball 208 falling off, and improving the stability of the structural parts of the electronic device 400.

[0057] According to some embodiments of the present application, Fig.12 As shown, optionally, a second gap 314 is provided between at least one of the second bracket 304 and the positioning portion 312 and the ball 208 .

[0058] In this embodiment, there is a gap between the ball 208 and at least one of the second bracket 304 and the positioning portion 312. This design reduces the friction between the ball 208 and the second bracket 304 and the positioning portion 312, allowing the ball 208 to roll flexibly when the electronic device 400 is opened and closed, increasing the flexibility of the rotation of the ball 208, thereby reducing the sluggish feeling of opening and closing when the electronic device 400 falls.

[0059] Specifically, there is a gap between the ball 208 and the second bracket 304, and the ball 208 is in contact with the positioning portion 312; or the ball 208 is in contact with the second bracket 304, and there is a gap between the ball 208 and the positioning portion 312; or there is a gap between the ball 208 and the second bracket 304, and there is a gap between the ball 208 and the positioning portion 312.

[0060] According to some embodiments of the present application, Figure 6 and Figure 7 As shown, optionally, the frame assembly 100 further includes a buffer assembly 316 , which is disposed on the hinge cover 206 and opposite to the ball assembly 500 .

[0061] In this embodiment, a buffer assembly 316 is provided on the hinge cover 206. When the electronic device 400 falls, the frame 300 is deformed, causing the ball assembly 500 to contact the buffer assembly 316 on the hinge cover 206. The buffer assembly 316 resists the impact force of the ball assembly 500, thereby reducing the deformation of the frame 300 and the risk of contact between the frame 300 and the cover surface of the hinge cover 206, thereby ensuring the normal function of the electronic device 400 when opening and closing, and not affecting the opening and closing effect.

[0062] According to some embodiments of the present application, Figure 7 As shown, optionally, the hinge cover 206 is provided with a second mounting groove 318 , and the buffer assembly 316 is located in the second mounting groove 318 .

[0063] In this embodiment, a second mounting groove 318 of the buffer component 316 is provided on the hinge cover 206, and the buffer component 316 can be fixed so that it is opposite to the ball 208. The buffer component 316 is placed in the second mounting groove 318, and the distance between the buffer component 316 and the frame 300 is increased to avoid interference caused by direct contact between the two, thereby ensuring smoothness when the electronic device 400 is opened and closed.

[0064] According to some embodiments of the present application, Figure 6 and Figure 7 As shown, optionally, the buffer component 316 is a rubber member, a foam metal member or an artificial cartilage bionic energy absorbing member (ACF, Artificial Cartilage Foam).

[0065] In this embodiment, the material of the buffer component 316 can be selected to be rubber parts, foam metal parts or artificial cartilage bionic energy-absorbing parts. The main function of the buffer component 316 is to absorb the impact force exerted on the frame 300 and reduce the deformation of the frame 300. Since rubber parts, foam metal parts or artificial cartilage bionic energy-absorbing materials have strong absorption capacity and flexibility, the above materials absorb the impact force exerted on the frame 300, alleviate the deformation of the frame 300, reduce the friction between the frame 300 and the hinge cover 206, and thus improve the smoothness of opening and closing of the electronic device 400.

[0066] Specifically, an energy absorbing block is installed on the end surface of the hinge cover 206, and its material is a buffer energy absorbing material (such as rubber, artificial cartilage bionic energy absorbing parts, foam metal). When the electronic device 400 falls off the frame 300 and deforms, and the ball contacts and squeezes the energy absorbing block on the end surface of the hinge cover 206, the energy absorbing block can absorb the deformation energy, further reduce the deformation degree of the frame 300, reduce the squeezing force between the ball and the end surface of the hinge cover 206, reduce the rolling friction, and significantly improve the opening and closing feel of the electronic device 400 and improve the reliability of the whole machine.

[0067] According to some embodiments of the present application, Fig.13 As shown, optionally, a third gap 324 is provided between the ball bearing 208 and the hinge cover 206 .

[0068] In this embodiment, when the frame 300 is not deformed, a third gap 324 exists between the ball bearing 208 and the hinge cover 206 , and when the ball bearing 208 and the hinge cover 206 are not in contact, the smooth opening and closing of the electronic device 400 is ensured.

[0069] Specifically, when the electronic device 400 falls and the frame 300 is deformed, the gap between the ball 208 and the hinge cover 206 can be set to alleviate the contact between the ball 208 and the hinge cover 206, reducing the risk of direct contact between the frame 300 and the hinge cover 206, so that the electronic device 400 has stability when opening and closing.

[0070] According to some embodiments of the present application, Figure 8 As shown, optionally, the frame body 300 includes a covering portion 320 , the covering portion 320 is located outside the end surface of the hinge cover 206 , and the first mounting groove 302 is disposed on the covering portion 320 .

[0071] In this embodiment, the covering portion 320 is arranged corresponding to the end surface of the hinge cover 206, and the ball 208 is installed on the covering portion 320, so that the position of the roller component is fixed corresponding to the hinge cover 206, thereby ensuring the overall position of the structural parts of the electronic device 400, improving the reliability of the risk of the electronic device 400 falling, and at the same time improving the overall sealing of the electronic device 400.

[0072] According to some embodiments of the present application, Figure 3 , Figure 4 , Figure 8 and Fig.12 As shown, optionally, the first installation groove 302 is a through hole 322 penetrating the frame 300 .

[0073] In this embodiment, the first mounting groove 302 is set as a through hole 322, and the ball 208 is placed in the first mounting groove 302 so that the ball 208 rests on the positioning portion 312. The second bracket 304 is installed from the side of the first mounting groove 302 away from the ball 208, the oil storage chamber 306 is filled with lubricating oil, and the sealing cover 310 closes the first mounting groove 302. This arrangement is convenient for the structural parts in the first mounting groove 302, has a simple design, and is convenient for the assembly of the electronic device 400.

[0074] According to some embodiments of the present application, Fig.12 and Fig.13 As shown, optionally, the ball 208 is a spherical ball.

[0075] In this embodiment, the ball bearing 208 is a spherical ball bearing, which is characterized by being able to rotate freely. When the electronic device 400 falls, the frame 300 contacts the end surface of the hinge cover 206. Since the spherical component can rotate freely, the rolling friction is much smaller than the sliding friction after the conventional zero-matching interference. Therefore, when the electronic device 400 is opened and closed, the spherical ball bearing can roll on the end surface of the hinge cover 206, reducing the risk of the electronic device 400 getting stuck or stuck.

[0076] like Fig.14As shown, the electronic device 400 further includes a screen assembly 402 , and the screen assembly 402 is disposed in the frame 300 .

[0077] like Fig.15 and Fig.16 As shown, the electronic device 400 includes a frame 300 and a hinge cover 206. The frame 300 extends to both sides of the hinge cover 206. The parts of the frame 300 extending to both sides of the hinge cover 206 are prone to deformation when they fall and are impacted. By arranging ball assemblies on the parts of the frame 300 extending to both sides of the hinge cover 206, during the rotation of the frame assembly 100 relative to the hinge assembly 200, the ball assembly 500 rolls on the surface of the hinge cover 206. The ball assembly 500 between the frame assembly 100 and the hinge cover 206 resists the deformation of the frame assembly 100, and reduces the contact between the surface of the frame assembly 100 and the hinge cover 206, thereby alleviating the jamming feeling when the electronic device 400 is opened and closed.
