Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a rotating shaft mechanism and electronic equipment. Background Art

[0002] With the gradual maturity of flexible display technology, the display mode of electronic devices has undergone very big changes. Foldable flexible screen mobile phones, foldable flexible screen tablets, and wearable electronic devices with foldable flexible screens are an important evolution direction of future smart electronic devices.

[0003] As foldable electronic devices become thinner and lighter, the thickness of some components of foldable electronic devices exceeds the thickness of the body, resulting in a bulge on one side of the middle frame of the foldable electronic device, causing an uneven appearance. In order to avoid the bulge when the foldable electronic device is folded, a groove is provided on the other side of the middle frame of the foldable electronic device so that the bulge can be accommodated in the groove, thereby achieving seamless folding of the foldable electronic device. However, when the electronic device is unfolded, the groove of the middle frame will destroy the overall aesthetics of the electronic device, and foreign objects can easily fall into the groove, affecting the user experience. Summary of the invention

[0004] The present application provides a hinge mechanism and an electronic device, which are used to cover a groove when the electronic device is in an unfolded state, thereby preventing particles such as dust from falling into the groove and improving the aesthetics of the electronic device.

[0005] In the first aspect, the present application provides a rotating shaft mechanism. The rotating shaft mechanism includes a rotating module, a first shell, a second shell and a shielding module. Specifically, the first shell and the second shell are arranged on both sides of the rotating module, and the first shell and the second shell are respectively rotatably connected to the rotating module. A protrusion is provided on the side of the first shell away from the rotating module, and a groove is provided on the side of the second shell away from the rotating module, and the protrusion and the groove are symmetrically arranged relative to the rotating module. The shielding module includes a shielding slider and at least one reset assembly. Among them, the shielding slider is at least partially accommodated in the groove, and the shielding slider can slide in the groove along the thickness direction of the second shell. The reset assembly includes a reset slider and a reset spring, the reset slider is arranged on one side of the shielding slider, and the reset slider abuts against the shielding slider. The reset slider is slidably connected to the second shell, and the sliding direction of the reset slider is not parallel to the sliding direction of the shielding slider. The reset spring is connected between the reset slider and the second shell.

[0006] The above-mentioned hinge mechanism is applied to a foldable electronic device. When the first shell and the second shell are folded relative to each other, the protrusion moves toward the groove, and the protrusion pushes the shielding slider to slide in the groove in a first direction away from the first shell, thereby pushing the reset slider to slide relative to the second shell, and compressing the reset spring at the same time, so that the protrusion is accommodated in the groove. When the first shell and the second shell are unfolded relative to each other, the reset spring applies a reset force to the reset slider, so that the reset slider slides relative to the second shell, and pushes the shielding slider to slide in the groove in a direction opposite to the first direction, so that the shielding slider shields the groove. Therefore, when the electronic device is folded, the protrusion pushes the shielding slider to one end of the groove away from the first shell, so that the protrusion is accommodated in the groove. When the electronic device is unfolded, the protrusion is disengaged from the groove, and the shielding slider slides to one end of the groove facing the first shell under the action of the reset assembly, so that the shielding slider can shield the groove to prevent particles such as dust from falling into the groove, and improve the aesthetics of the electronic device.

[0007] When the sliding connection between the shielding slide groove and the groove is specifically set, a limit slide groove is set on the inner wall of the groove, and the limit slide groove extends along the thickness direction of the second shell. The shielding slider includes a slider body and a limit protrusion, and the limit protrusion is located on the side of the slider body facing the limit slide groove. The limit protrusion is accommodated in the limit slide groove, and the limit protrusion realizes the sliding connection between the shielding slider and the groove by sliding in the limit slide groove.

[0008] In a possible implementation, the shielding slider has a contact surface that abuts against the reset slider, and the contact surface is not parallel to the sliding direction of the reset slider. When the protrusion pushes the shielding slider to slide in the groove, or when the reset slider pushes the shielding slider to slide in the groove, the contact point between the reset slider and the shielding slider moves along the contact surface, so that the reset slider and the shielding slider move along their respective sliding directions.

[0009] The number of the at least one reset component mentioned above is not limited. In one possible implementation, the shielding module may include a reset component. The reset component is located on one side of the shielding slider. In another possible implementation, the shielding module may include a first reset component and a second reset component. The first reset component includes a first reset slider and a first reset spring, and the second reset component includes a second reset slider and a second reset spring. The first reset slider and the second reset slider are relatively arranged on both sides of the shielding slider, and are respectively abutted against the shielding slider. The sliding direction of the first reset slider is opposite to the sliding direction of the second reset slider and is perpendicular to the sliding direction of the shielding slider. One end of the first reset spring is connected to one end of the first reset slider away from the shielding slider, and the other end is connected to the second shell. One end of the second reset spring is connected to one end of the second reset slider away from the shielding slider, and the other end is connected to the second shell.

[0010] When the at least one reset component is specifically arranged, the second shell may be provided with a receiving groove, which may be communicated with the groove, and the extending direction of the receiving groove is the same as the sliding direction of the reset slider. The at least one reset component may be accommodated in the receiving groove. Specifically, a fixing column is provided on the inner wall of the end of the receiving groove away from the groove. The reset slider is arranged close to the groove. One end of the reset spring is connected to the end of the reset slider away from the groove, and the other end is sleeved on the fixing column. In this implementation, the reset component is detachably connected to the second shell to facilitate assembly and disassembly of the shielding module.

[0011] In a possible implementation, the first shell is provided with a snap-fit ​​edge for snapping with the second shell. Specifically, a protrusion is provided on the snap-fit ​​edge. The shielding module also includes a baffle, which is arranged opposite to the snap-fit ​​edge relative to the base, and the baffle is rotatably connected to the second shell. When the first shell and the second shell are relatively folded, the snap-fit ​​edge abuts against the baffle and pushes the baffle to rotate, so that the shielding module avoids the snap-fit ​​edge. When the first shell and the second shell are relatively unfolded, the reset slider slides relative to the second shell and pushes the baffle to rotate, so that the baffle shields the reset component, thereby improving the aesthetics of the electronic device when unfolded.

[0012] In a possible implementation, the end of the reset slider away from the shielding slider has an inclined surface that abuts against the baffle. The inclined surface is not parallel to the sliding direction of the reset slider, and the inclined surface is not parallel to the rotation plane of the baffle. When the reset slider slides relative to the second housing, the contact point between the baffle and the reset slider moves along the inclined surface, so that the reset slider pushes the baffle to rotate while sliding along the sliding direction.

[0013] In a possible implementation, a side of the second housing close to the baffle has a limiting portion extending toward the baffle, and the limiting portion is used to limit the rotation angle of the baffle to prevent the baffle from excessively rotating.

[0014] In a second aspect, the present application provides an electronic device, which includes a flexible display screen and the hinge mechanism of the first aspect, wherein the flexible display screen continuously covers one side of the hinge mechanism and is fixedly connected to the hinge mechanism.

[0015] When the electronic device is folded, the protrusion pushes the shielding slider to the end of the groove away from the first housing, so that the protrusion can be accommodated in the groove. When the electronic device is unfolded, the protrusion is separated from the groove, and the shielding slider slides to the end of the groove facing the first housing under the action of the reset assembly, so that the shielding slider can shield the groove, thereby improving the aesthetics of the electronic device.

[0016] The electronic device may be an outward-folding electronic device, specifically, the protrusion is located on the side of the first shell away from the flexible display screen, and the groove is located on the side of the second shell away from the flexible display screen. Of course, the electronic device may also be an inward-folding electronic device, specifically, the protrusion is located on the side of the first shell facing the flexible display screen, and the groove is located on the side of the second shell facing the flexible display screen.

[0086] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0087] In order to facilitate understanding of the hinge mechanism provided in the embodiment of the present application, its application scenario is described below. The hinge mechanism can be applied to, but is not limited to, foldable electronic devices such as mobile phones, smart wearable devices, tablet computers, or laptop computers. When the hinge mechanism provided in the embodiment of the present application is applied to electronic devices, please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of an electronic device provided in an embodiment of the present application, Figure 2 The electronic device 10 provided in the present application may be an outward-folding electronic device or an inward-folding electronic device.

[0088] like Figure 1 and Figure 2As shown, the electronic device 10 includes a hinge mechanism 11 and a flexible display screen 12, wherein the hinge mechanism 11 includes a rotating module 110, a first shell 111 and a second shell 112. Specifically, the first shell 111 and the second shell 112 are arranged on both sides of the rotating module 110, and the first shell 111 and the second shell 112 are respectively rotatably connected to the rotating module 110, so that the first shell 111 and the second shell 112 can be folded and unfolded through the rotating module 110. The flexible display screen 12 is located on one side of the hinge mechanism 11 and covers the hinge mechanism 11.

[0089] When the electronic device 10 is used, it can be folded and unfolded according to different usage scenarios. Figure 1 As shown, when the electronic device 10 is in a folded state, the first housing 111 and the second housing 112 are arranged opposite to each other. At this time, the flexible display screen 12 can be used as both a display surface of the electronic device 10 and an appearance surface of the electronic device 10. Figure 2 As shown, when the electronic device 10 is in the unfolded state, the flexible display screen 12 is located on the same side of the rotating module 110, the first shell 111 and the second shell 112. At this time, the flexible display screen 12 serves as the display surface of the electronic device 10, and the outer surface of the first shell 111 away from the flexible display screen 12 and the outer surface of the second shell 112 away from the flexible display screen 12 together serve as the appearance surface of the electronic device 10. Of course, the above-mentioned electronic device 10 can also be an inward folding electronic device. When the electronic device 10 is in the folded state, the first shell 111, the second shell 112 and the rotating module 110 can form an accommodating space, which is shaped like a water drop, and the bent part of the flexible display screen 12 can be accommodated in the accommodating space to avoid pulling or squeezing the flexible display screen 12, thereby reducing the risk of damage to the flexible display screen 12.

[0090] It is understandable that the process of the electronic device 10 changing from the unfolded state to the folded state, or from the folded state to the unfolded state, is the process of the first housing 111 and the second housing 112 rotating around the rotating module 110. The flexible display screen 12 is bent or flattened along with the first housing 111 and the second housing 112 during this process.

[0091] In some current foldable electronic devices, the middle frame of the first housing has a protrusion, and the middle frame of the second housing has a groove corresponding to the protrusion. When the electronic device is in a folded state, the protrusion is accommodated in the groove to achieve seamless folding of the electronic device. However, when the electronic device is in a flattened state, the groove is exposed to the air and is prone to falling into small particles such as external dust and water droplets, which affects the function of the electronic device and also affects the aesthetics of the overall structure of the electronic device.

[0092] Therefore, the present application provides a hinge mechanism and an electronic device to cover the groove when the electronic device is in an unfolded state, thereby preventing particles such as dust from falling into the groove and improving the aesthetics of the electronic device.

[0093] It should be noted that the terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and appended claims of the present application, the singular expressions "a", "an", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear indication to the contrary in the context.

[0094] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0095] The electronic device provided in the present application is described in detail below as an outward folding electronic device.

[0096] Figure 3 A schematic diagram of a rotating shaft mechanism provided in an embodiment of the present application in a folded state, Figure 4 This is a schematic diagram of the rotating shaft mechanism provided in the embodiment of the present application in an unfolded state. Figure 3 and Figure 4 As shown, the hinge mechanism 11 includes a rotating module 110, a first shell 111, a second shell 112 and a shielding module 113. Specifically, the first shell 111 and the second shell 112 are symmetrically arranged on both sides of the rotating module 110, and the first shell 111 and the second shell 112 are rotatably connected to the rotating module 110 respectively.

[0097] Figure 5 A schematic diagram of a first housing provided in an embodiment of the present application. Figure 5As shown, one side of the first housing 111 is rotatably connected to the rotating module 110, and a protrusion 1111 is provided on the side of the first housing 111 away from the rotating module 110. It should be noted that the protrusion 1111 in the embodiment of the present application may be a locking member, and is used to cooperate with the locking member of the second housing 112 to keep the hinge mechanism 11 in a folded state; or, the protrusion 1111 may also be a protruding portion of the first housing 111, which is caused by the thickness of a local device inside the electronic device 10 exceeding the thickness of the entire device.

[0098] Figure 6 A schematic diagram of a second housing provided in an embodiment of the present application, Figure 7 This is an exploded view of the second housing provided in the embodiment of the present application. Figure 6 and Figure 7 As shown, one side of the second housing 112 is rotatably connected to the rotating module 110, and a groove 1121 is provided on the side of the second housing 112 away from the rotating module 110. The protrusion 1111 and the groove 1121 are symmetrically arranged relative to the rotating module 110. When the first housing 111 and the second housing 112 are relatively folded, the protrusion 1111 moves toward the groove 1121 and is accommodated in the groove 1121. A receiving groove 1120 is provided on the side of the second housing 112 away from the rotating module 110, and the receiving groove 1120 is communicated with the groove 1121. The shielding module 113 is arranged in the receiving groove 1120 and the groove 1121.

Figure 8 As shown, the shielding module 113 may specifically include a first reset component 1131, a second reset component 1132 and a shielding slider 1133. The shielding slider 1133 is at least partially accommodated in the groove 1121 and can be moved in the groove 1121 along the thickness direction of the second housing 112 (i.e. Figure 3 The first reset component 1131 and the second reset component 1132 are accommodated in the accommodation groove 1120, and the first reset component 1131 and the second reset component 1132 are located on both sides of the shielding slider 1133.

Fig. 9 and Fig.10 As shown, in one embodiment, the shielding slider 1133 includes a slider body 11331 and a limiting protrusion 11332, wherein the limiting protrusion 11332 is used for sliding connection with the groove 1121. The slider body 11331 has a first contact surface S21 and a second contact surface S22.

[0101] The first contact surface S21 faces the first reset slider 11311 , and the first contact surface S21 is not parallel to the sliding direction of the first reset slider 11311 .

[0102] The second contact surface S22 faces the second reset slider 11321, and the second contact surface S22 is not parallel to the sliding direction of the second reset slider 11321. In this embodiment, the inclined direction of the surface is based on the thickness direction of the whole device.

Fig.12 and Fig.13 As shown, the inner wall of the groove 1121 is provided with a limiting sliding groove 11211 , and the limiting sliding groove 11211 extends along the thickness direction of the second shell 112 .

[0105] Fig.14 A schematic diagram of a shielding slider and a groove provided in an embodiment of the present application. Fig.14 As shown, in one embodiment, a portion of the slider body 11331 is accommodated in the accommodation groove 1120, and another portion is accommodated in the groove 1121. The limiting protrusion 11332 is accommodated in the limiting sliding groove 11211, and the sliding connection between the shielding slider 1133 and the groove 1121 is achieved by sliding in the limiting sliding groove 11211. Fig.15 Another schematic diagram of a shielding slider and a groove provided in an embodiment of the present application, Fig.16 for Fig.15 The cross-sectional view of the shielded slider and groove along the MM direction. Fig.15 and Fig.16 As shown, when the electronic device 10 is in a flattened state, the shielding slider 1133 slides to an end of the groove 1121 away from the bottom wall S of the accommodating groove 1120 to shield the groove 1121 . Fig.17 Another schematic diagram of a shielding slider and a groove provided in an embodiment of the present application, Fig.18 Another schematic diagram of the shielding slider and the groove provided in the embodiment of the present application. Fig.17 and Fig.18As shown, when the electronic device 10 is in the folded state, the shielding slider 1133 slides to the end of the groove 1121 close to the bottom wall S of the receiving groove 1120, so that the protrusion 1111 can be received in the groove 1121. Fig.15 and Fig.17 As shown, the inner walls of the limiting slide groove 11211 at both ends along the thickness direction of the second shell 112 can limit the limiting protrusion 11332 in the limiting slide groove 11211, thereby preventing the shielding slider 1133 from escaping from the groove 1121.

[0106] In application, when the electronic device 10 is in a flat state, Fig.15 and Fig.16 As shown, the shielding slider 1133 is located at one end of the groove 1121 away from the bottom wall S of the receiving groove 1120. When the electronic device 10 is folded, the first housing 111 and the second housing 112 are folded relative to each other. The protrusion 1111 rotates toward the groove 1121 along with the first housing 111 and abuts against the shielding slider 1133. When the electronic device 10 is folded further, the protrusion 1111 can push the shielding slider 1133 to slide in the groove 1121 and reach the end of the groove 1121 close to the bottom wall S of the receiving groove 1120, as shown in FIG. Fig.17 and Fig.18 At this time, the protrusion 1111 extends into and is accommodated in the groove 1121.

[0107] When the electronic device 10 is unfolded, the protrusion 1111 is disengaged from the groove 1121. Under the resetting action of the first resetting component 1131 and the second resetting component 1132, the shielding slider 1133 slides in the groove 1121 in a direction away from the bottom wall S of the receiving groove 1120, and reaches the end of the groove 1121 away from the bottom wall S of the receiving groove 1120. At this time, the shielding slider 1133 can shield the groove 1121 from the user's perspective to prevent particles such as dust from falling into the groove 1121.

[0112] Specifically, the extending direction of the receiving groove 1120 can be the same as the sliding direction of the first reset slider 11311 and the sliding direction of the second reset slider 11321, so that the first reset slider 11311 realizes the sliding connection between the first reset slider 11311 and the second shell 112 by sliding in the receiving groove 1120, and the second reset slider 11321 realizes the sliding connection between the second reset slider 11321 and the second shell 112 by sliding in the receiving groove 1120.

Fig.26 and Fig. 27As shown, when the electronic device 10 is in a flattened state, the shielding slider 1133 is located at one end of the groove 1121 away from the bottom wall S of the receiving groove 1120. The side of the first contact surface S21 close to the bottom wall S abuts against the side of the first inclined surface S11 away from the bottom wall S, and the side of the second contact surface S22 close to the bottom wall S abuts against the side of the second inclined surface S12 away from the bottom wall S. When the electronic device 10 is folded, the shielding slider 1133 slides in the groove 1121 in a direction close to the bottom wall S. At this time, the first contact surface S21 moves toward the direction close to the bottom wall S, and the first contact surface S21 and the first inclined surface S11 slide against each other, so that the shielding slider 1133 provides a first thrust F1 perpendicular to the first inclined surface S11 to the first reset slider 11311. Since the first contact surface S21 is not parallel to the sliding direction of the first reset slider 11311, the first thrust F1 has a first component force f1 along the sliding direction of the first reset slider 11311. The direction of the first component force f1 is as follows: Fig. 27 The first component force f1 can push the first reset slider 11311 to slide in a direction away from the second reset slider 11321 (i.e., the direction in which the first reset spring 11312 is compressed).

Since the second contact surface S22 is not parallel to the sliding direction of the second reset slider 11321, the second thrust F2 has a second component f2 along the sliding direction of the second reset slider 11321. The direction of the second component f2 is as shown in FIG. Fig. 27 The second component force f2 can push the second reset slider 11321 to slide in a direction away from the first reset slider 11311 (ie, a direction to compress the second reset spring 11322).

One end of the first reset spring 11312 away from the first reset slider 11311 is sleeved on the first fixing column 11201. When the first reset slider 11311 moves in a direction away from the second reset slider 11321, the first reset slider 11311 compresses the first reset spring 11312. When the electronic device 10 is unfolded, the first housing 111 and the second housing 112 are unfolded. The first reset spring 11312 provides a first reset force to the first reset slider 11311, and the first reset slider 11311 slides toward the second reset slider 11321 under the action of the first reset force, thereby pushing the shielding slider 1133 to slide in the groove 1121 to one end away from the bottom wall S.

[0118] Please continue reading Fig. 27 and Fig.30 , during the sliding process of the first reset slider 11311 toward the second reset slider 11321, the first inclined surface S11 moves toward the direction close to the second reset slider 11321, and the first contact surface S21 and the first inclined surface S11 slide against each other, so that the first reset slider 11311 provides the shielding slider 1133 with a third thrust F3 perpendicular to the first inclined surface S11 (the third thrust F3 is opposite to the first thrust F1). Since the first contact surface S21 is not parallel to the sliding direction of the first reset slider 11311, the third thrust F3 has a third component f3 along the sliding direction of the shielding slider 1133, and the direction of the third component f3 is as shown in FIG.

One end of the second reset spring 11322 away from the second reset slider 11321 is sleeved on the second fixing column 11202. When the second reset slider 11321 moves in a direction away from the first reset slider 11311, the second reset slider 11321 compresses the second reset spring 11322. When the electronic device 10 is unfolded, the first housing 111 and the second housing 112 are unfolded. The second reset spring 11322 provides a second reset force to the second reset slider 11321, and the second reset slider 11321 slides toward the first reset slider 11311 under the action of the second reset force, thereby pushing the shielding slider 1133 to slide in the groove 1121 to the end away from the bottom wall S.

Since the second contact surface S22 is not parallel to the sliding direction of the second reset slider 11321, the fourth thrust F4 has a fourth component force f4 along the sliding direction of the shielding slider 1133, and the direction of the fourth component force f4 is as shown in FIG. Fig. 27 The fourth force component f4 can push the shielding slider 1133 to slide in a direction away from the bottom wall S.
