Description

Technical Field

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

[0002] With the development of technology, electronic devices such as mobile phones, tablet computers, and laptops have gradually become popular. As user demand increases, foldable screen electronic devices have emerged to take into account users' demand for large screens and the portability of electronic devices.

[0003] Folding screen electronic devices use a flexible display screen and a hinge mechanism to achieve the unfolding and folding of the electronic device. The hinge mechanism includes a door panel. When the hinge mechanism is in the folded state, the door panel clamps the foldable part of the flexible display screen to form a water drop angle; when the hinge mechanism is in the unfolded state, the door panel supports the foldable part of the flexible display screen to help the foldable part of the flexible display screen to flatten.

[0004] The pivot mechanism also includes a shaft cover, a base, a connecting block and a swing arm, wherein the base is fixedly connected to the shaft cover, and the swing arm is rotatably connected to the base. The swing arm and the connecting block can control the movement of the door panel. Usually, there is an arc groove on the door panel, and the pin at the end of the swing arm is inserted into the arc groove. During the unfolding and folding process of the pivot mechanism, the pin is always in the arc groove. In the case where the shaft cover is wider and the door panel is narrower, the length of the arc groove becomes shorter due to the narrowing of the door panel, but the movement stroke of the pin at the end of the swing arm does not change, which may cause the pin to slip out of the arc groove during the unfolding and folding process of the pivot mechanism, that is, the swing arm is separated from the door panel, affecting the user experience. Summary of the invention

[0005] The present application provides a rotating shaft mechanism and a foldable electronic device to solve the technical problem that the pin shaft on the swing arm will be separated from the arc groove on the door panel in the case of a wide shaft cover and a narrow door panel.

[0006] The technical solution is as follows:

[0007] A first aspect of the present application provides a rotating shaft mechanism, which includes: a base, a first swing arm and a door panel;

[0008] One end of the first swing arm is rotatably connected to the base, the first swing arm can rotate between an unfolded position and a folded position relative to the base, and a guide assembly is provided on the first swing arm, and the guide assembly includes a first guide member and a second guide member;

[0009] The door panel is movably connected to the first swing arm through the guide assembly;

[0010] Wherein, when the first swing arm is in the unfolded position relative to the base, the door panel overlaps with the first guide member; when the first swing arm is in the folded position relative to the base, the door panel overlaps with the second guide member.

[0011] By adopting the above-mentioned scheme, the present application utilizes the first guide member and the second guide member to be arranged on the first swing arm so as to achieve overlapping with the door panel in an alternating manner, thereby ensuring that when the first swing arm is switched between the unfolded position and the folded position, an effective movable connection is always maintained between the first swing arm and the door panel.

[0012] In some implementations, when the first swing arm is in the deployed position relative to the base, a distance between the first guide and the base is smaller than a distance between the second guide and the base.

[0013] By adopting the above scheme, when the first swing arm is in the expanded position relative to the base, the relative positions of the first guide member and the second guide member on the first swing arm are limited, so that the overlapping connection between the first guide member and the door panel can be connected to the overlapping connection between the second guide member and the door panel, thereby ensuring that the door panel and the first swing arm will not be separated when the first swing arm is converted between the expanded position and the folded position, which is conducive to precise control of the movement of the door panel.

[0014] In some implementations, when the first swing arm is in the deployed position relative to the base, a distance between a boundary line of the first guide member that is closest to the base in a projection on a set plane and a boundary line of the second guide member that is farthest from the base in a projection on the set plane is greater than either the first distance or the second distance.

[0015] The first distance is the width of the projection of the first guide member in the setting plane in the width direction of the rotating shaft mechanism, and the second distance is the width of the projection of the second guide member in the setting plane in the width direction of the rotating shaft mechanism;

[0016] The setting plane is perpendicular to the thickness direction of the rotating shaft mechanism, and the setting plane is parallel to the width direction of the rotating shaft mechanism.

[0017] By adopting the above scheme, when the first swing arm is in the expanded position relative to the base, the first guide member and the second guide member are staggered in relative positions on the first swing arm in the width direction of the rotating shaft mechanism, so that the first guide member and the second guide member can be converted to overlap with the door panel respectively, so as to ensure that the door panel and the first swing arm will not separate.

[0018] In some implementations, when the first swing arm is in the deployed position relative to the base, a projection of the first guide member in a set plane and a projection of the second guide member in the set plane are spaced apart in a width direction of the rotating shaft mechanism;

[0019] The setting plane is perpendicular to the thickness direction of the rotating shaft mechanism, and the setting plane is parallel to the width direction of the rotating shaft mechanism.

[0020] By adopting the above scheme, when the first swing arm is in the expanded position relative to the base, the first guide member and the second guide member are spaced apart from each other in relative positions on the first swing arm in the width direction of the pivot mechanism to ensure that the door panel and the first swing arm will not disengage.

[0021] In some implementations, the door panel is provided with a first slide groove corresponding to the first guide member and a second slide groove corresponding to the second guide member;

[0022] When the first swing arm is in the unfolded position relative to the base, the first guide member is inserted into the first slide groove;

[0023] When the first swing arm is in the folded position relative to the base, the second guide member is inserted into the second slide groove.

[0024] By adopting the above solution, the first guide member and the second guide member are respectively inserted into the corresponding sliding grooves, so as to ensure that the door panel and the first swing arm will not be separated when the first swing arm moves.

[0025] In some implementations, the door panel includes a panel body and a first slot seat, the first slot seat is fixedly connected to the panel body, and the first slide groove and the second slide groove are provided on the first slot seat;

[0026] The length direction of the plate body is parallel to the length direction of the rotating shaft mechanism.

[0027] By adopting the above solution, a first groove seat is arranged on the plate body so as to provide a first sliding groove and a second sliding groove respectively matched with the first guide member and the second guide member.

[0028] In some implementations, the first slot seat has a first side and a second side opposite to each other, and a direction from the first side to the second side is parallel to a length direction of the plate body; wherein,

[0029] The first slide groove is located at the first side, and the second slide groove is located at the second side;

[0030] Or, the first slide groove and the second slide groove are both located on the first side, and the first slide groove and the second slide groove are spaced apart in the thickness direction of the plate body;

[0031] Alternatively, the first sliding groove and the second sliding groove are both located on the second side, and the first sliding groove and the second sliding groove are spaced apart in a thickness direction of the plate body.

[0032] By adopting the above scheme, the first slide groove and the second slide groove are respectively arranged on the opposite sides of the first groove seat, or the first slide groove and the second slide groove are simultaneously arranged on either side of the first groove seat to adapt to different application scenarios, so as to ensure the accuracy of controlling the movement of the door panel.

[0033] In some implementations, the first slide groove is curved, and the second slide groove is curved.

[0034] By adopting the above solution, the first sliding groove and the second sliding groove are curved, so that the door panel can move along with the first swing arm.

[0035] In some embodiments, both ends of the first slide groove in the length direction are open, and one end of the second slide groove in the length direction is closed.

[0036] By adopting the above solution, it is beneficial to accurately control the angle of the door panel.

[0037] In some implementations, the first slide groove corresponds to one of the first guide members; and the second slide groove corresponds to one of the second guide members.

[0038] By adopting the above scheme, the first slide groove is a non-circular groove, and the second slide groove is a non-circular groove. When the first slide groove cooperates with more than two first guide members, and the second slide groove cooperates with more than two second guide members, the movement of any two first guide members will interfere, and the movement of any two second guide members will interfere, so that a preset style of movement will not be generated between the door panel and the swing arm; therefore, the first slide groove only cooperates with one first guide member, and the second slide groove only cooperates with one second guide member, so as to ensure that the relative movement between the swing arm and the door panel meets the design requirements.

[0039] In some implementations, the first guide member and the second guide member are both columnar structures;

[0040] One end of the first guide member is fixedly connected to the first swing arm, and the other end of the first guide member opposite thereto can be inserted into the first sliding groove;

[0041] One end of the second guide member is fixedly connected to the first swing arm, and the other end of the second guide member opposite thereto can be inserted into the second sliding groove.

[0042] By adopting the above solution, the first guide member and the second guide member adopt a columnar structure, so that the contact form between the first guide member and the first slide groove is a high pair, and the contact form between the second guide member and the second slide groove is a high pair.

[0043] In some implementations, a direction from one end of the first guide member to another end opposite to the first guide member is the same as a direction from one end of the second guide member to another end opposite to the second guide member;

[0044] Alternatively, a direction from one end of the first guide member to the other end opposite to the first guide member is opposite to a direction from one end of the second guide member to the other end opposite to the second guide member.

[0045] By adopting the above solution, the first guide member and the second guide member are arranged opposite to each other on the first swing arm, or the first guide member and the second guide member are arranged in the same direction on the first swing arm, so as to be suitable for different application scenarios.

[0046] In some implementations, the first swing arm has a recessed groove, and the first groove seat is located in the recessed groove; wherein,

[0047] The first guide member and the second guide member are respectively located on two different groove walls opposite to each other of the recessed groove; or, the first guide member and the second guide member are respectively located on the groove wall on the same side of the recessed groove.

[0048] By adopting the above solution, the guide assembly on the first swing arm can be matched with the door panel.

[0049] In some embodiments, a radial cross-section of the columnar structure is circular or elliptical.

[0050] By adopting the above solution, it is beneficial to realize the movement of the first guide member and the second guide member in their respective corresponding slide grooves, and it is beneficial to reduce friction and increase the service life of the rotating shaft mechanism.

[0051] In some implementations, the hinge mechanism further includes a connecting block, and the connecting block is rotatably connected to the door panel.

[0052] By adopting the above solution, the connecting block is rotatably connected to the door panel, so as to realize stable movement of the door panel.

[0053] In some implementations, the hinge mechanism further includes a second swing arm, the second swing arm is rotatably connected to the base, and the second swing arm can rotate relative to the base between the unfolded position and the folded position;

[0054] The door panel is provided with a third slide groove, the second swing arm is provided with a first pin shaft, and the first pin shaft is inserted into the third slide groove.

[0055] By adopting the above solution, the second swing arm and the door panel cooperate with each other through the first pin shaft and the third slide groove. In this way, after the first swing arm and the second swing arm cooperate, the movement of the door panel can be better controlled and the stability of the door panel movement can be ensured.

[0056] In some implementations, the second swing arm is further hinged to the connecting block via a second pin.

[0057] By adopting the above solution, the second swing arm is hinged to the connecting block, so as to facilitate the folding and unfolding of the electronic device.

[0058] In some implementations, the door panel has a fourth curved slide groove, and the connecting block is fixed with a first sliding block that matches the fourth slide groove, and the first sliding block can move in the fourth slide groove.

[0059] By adopting the above solution, the fourth slide groove and the first slide block are matched between the connecting block and the door panel to achieve a low contact form between the connecting block and the door panel, thereby improving the stability of the connection between the connecting block and the door panel.

[0060] In some implementations, when the first slide groove and the second slide groove are both located on the first side of the first groove seat, the second side has a fifth slide groove in a curved shape, and the connecting block is provided with a second sliding block matched with the fifth slide groove;

[0061] Alternatively, when the first slide groove and the second slide groove are both located on the second side of the first groove seat, the first side has a fifth slide groove in a curved shape, and the connecting block is provided with a second sliding block matched with the fifth slide groove.

[0062] By adopting the above solution, the fifth sliding groove cooperates with the second sliding block to further accurately control the movement of the door panel.

[0063] In some implementations, a shape of the second sliding block is similar to a shape of the fifth sliding groove.

[0064] By adopting the above solution, it is advantageous to enable the second sliding block to move in the fifth sliding groove.

[0065] A second aspect of the present application provides a foldable electronic device, which includes a first sub-shell, a second sub-shell and any one of the above-mentioned hinge mechanisms, wherein the first sub-shell and the second sub-shell are respectively connected to the hinge mechanisms, and the first sub-shell and the second sub-shell can rotate relative to each other through the hinge mechanism.

[0066] By adopting the above scheme, after the hinge mechanism is applied to the electronic device, the first guide member and the second guide member are arranged on the first swing arm so that the first swing arm can be overlapped with the door panel in an alternating manner, thereby ensuring that when the first swing arm is switched between the unfolded position and the folded position, the first swing arm and the door panel always maintain an effective active connection.

In the description of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

[0110] The hinge mechanism and electronic device provided in the embodiments of the present application are explained in detail below.

[0112] In one or more embodiments, the present application provides an electronic device, which may be a foldable electronic device; the electronic device includes a housing and a hinge mechanism 100, the housing includes a first sub-shell 301 and a second sub-shell 302, the first sub-shell 301 and the second sub-shell 302 are respectively connected to the hinge mechanism 100, and the first sub-shell 301 and the second sub-shell 302 can rotate relative to each other through the hinge mechanism 100. Exemplary electronic devices may be mobile phones, tablet computers, notebooks, or e-readers. Foldable electronic devices are not limited to electronic devices with foldable display screens, such as mobile phones, but may also be electronic devices with display screens and keyboards that can be folded or unfolded, such as laptop computers.

[0113] In the embodiment of the present application, the electronic device is a mobile phone as an example, and the electronic device further includes a display screen 200, which can be a flexible display screen, and the display screen 200 is respectively connected to the first sub-shell 301 and the second sub-shell 302. The first sub-shell 301 and the second sub-shell 302 can include the middle frame of the mobile phone.

[0114] For ease of description, as shown in the figure, the width direction of the foldable electronic device can be defined as the BB direction, the length direction of the foldable electronic device can be defined as the AA direction, and the thickness direction of the foldable electronic device can be defined as the CC direction. The AA direction, the BB direction, and the CC direction are mutually perpendicular to each other to form a rectangular coordinate system.

[0115] Figure 1 The foldable electronic device is shown in a folded state. Figure 2 The foldable electronic device is shown in a semi-expanded state. Figure 3 The foldable electronic device is shown in an unfolded state. Figure 2 The unfolding angle α of the foldable electronic device shown is 90 degrees. Figure 3 The unfolding angle β of the foldable electronic device is 180 degrees. The state of the electronic device is the same as the state of the hinge mechanism 100, that is, when the foldable electronic device is in the folded state, the hinge mechanism 100 is also in the folded state; when the foldable electronic device is in the semi-expanded state, the hinge mechanism 100 is also in the semi-expanded state; when the foldable electronic device is in the unfolded state, the hinge mechanism 100 is also in the unfolded state.

[0116] It should be noted that the angles illustrated in the embodiments of the present application are allowed to have slight deviations. Figure 2 The unfolding angle α of the foldable electronic device shown is 90 degrees, which means that α can be 90 degrees, or approximately 90 degrees, such as 80 degrees, 85 degrees, 95 degrees or 100 degrees. Figure 3 The unfolding angle β of the foldable electronic device shown is 180 degrees, which means that β can be 180 degrees, or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees, etc. The angles described below can be understood in the same way.

[0117] See also Figure 4 , Figure 4 yes Figure 3 Schematic diagram of the exploded structure of the electronic device shown, Figure 4The figure only shows the position of the hinge mechanism 100, but does not limit the specific structural form of the hinge mechanism 100; the first subshell 301 and the second subshell 302 are respectively installed on both sides of the hinge mechanism 100 along the BB direction, and the display screen 200 includes a first part 201, a second part 202 and a foldable part 203. The foldable part 203 is located between the first part 201 and the second part 202, and the foldable part 203 can be bent along the AA direction. In this embodiment, the display screen 200 adopts a flexible display screen, for example, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (mini organic light-emitting diode) display screen, a microorganic light-emitting diode (microorganic light-emitting diode) display screen, a quantum dot light-emitting diode (quantum dot light-emitting diodes, QLED) display screen, and the like.

[0118] The first sub-shell 301 and the second sub-shell 302 are relatively close to each other to drive the display screen 200 to fold, so that the foldable electronic device can be folded. When the foldable electronic device is in the folded state, the foldable portion 330 of the display screen 200 is bent, and the first portion 201 and the second portion 202 are arranged opposite to each other. At this time, the display screen 200 is between the first sub-shell 301 and the second sub-shell 302, which can greatly reduce the probability of the display screen 200 being damaged, and effectively protect the display screen 200.

[0119] Please also read Figure 2 and Figure 4 , the first sub-shell 301 and the second sub-shell 302 rotate relative to each other through the hinge mechanism 100, and the first sub-shell 301 and the second sub-shell 302 move away from each other to drive the display screen 200 to unfold, so that the foldable electronic device is unfolded to a semi-expanded state. When the foldable electronic device is in the semi-expanded state, the first sub-shell 301 and the second sub-shell 302 unfold to an angle of α, the first part 201 and the second part 202 unfold relative to each other, and drive the foldable part 203 to unfold. At this time, the angle between the first part 201 and the second part 202 is α.

[0120] Please also read Figure 3 and Figure 4The first sub-shell 301 and the second sub-shell 302 rotate relative to each other through the hinge mechanism 100, and the first sub-shell 301 and the second sub-shell 302 move away from each other to drive the display screen 200 to further unfold until the foldable electronic device is flattened. The hinge mechanism 100 may have a damping mechanism to achieve the opening and closing feel and state maintenance during the rotation process.

[0121] When the electronic device is in a flattened state, the angle between the first sub-shell 301 and the second sub-shell 302 is β. The foldable portion 203 is unfolded, and the first portion 201 and the second portion 202 are relatively unfolded. At this time, the angles between the first portion 201, the second portion 202 and the foldable portion 203 are all β, and the display screen 200 has a large display area, realizing a large-screen display of the foldable electronic device, and improving the user experience.

[0122] It should be noted that the angle α and the angle β are both the angles between the first sub-shell 301 and the second sub-shell 302, which are only used to distinguish the different angles between the first sub-shell 301 and the second sub-shell 302 in different states of the foldable electronic device. The angle α refers to the angle between the first sub-shell 301 and the second sub-shell 302 when the foldable electronic device is in a semi-expanded state; the angle β refers to the angle between the first sub-shell 301 and the second sub-shell 302 when the foldable electronic device is in an expanded state.

The shaft cover can be fixedly connected to the base 101, for example, the shaft cover and the base 101 can be fixedly connected by screws, or the shaft cover and the base 101 can be an integral structure. The width of the shaft cover is parallel to the width direction of the pivot mechanism 100. In the expanded state, the width of the door panel 105 is parallel to the width direction of the pivot mechanism 100; the width direction of the shaft cover is parallel to the width direction of the pivot mechanism 100. One end of the first swing arm 102 is rotatably connected to the base 101; one end of the second swing arm 103 is rotatably connected to the base 101. The first swing arm 102 and the second swing arm 103 are distributed along the length direction of the pivot mechanism 100. When the pivot mechanism 100 is in the expanded state, the first swing arm 102 and the second swing arm 103 are both in the expanded position relative to the base 101. Figure 6Only a partial number of the first swing arm 102 and the second swing arm 103 are shown.

[0125] In some embodiments, the number of the door panels 105 is plural. The number of the first swing arms 102 may be an even number, and the number of the second swing arms 103 may be an even number. The door panels 105 are used to support the foldable portion 203 of the display screen 200 (which may be combined with the foldable portion 203 of the display screen 200). Figure 4 and Figure 5 The hinge mechanism 100 is connected to the first sub-shell 301 and the second sub-shell 302 respectively through different connecting blocks 104. The first sub-shell 301 is fixedly connected to its corresponding connecting block 104, and the second sub-shell 302 is fixedly connected to its corresponding connecting block 104, so as to realize the unfolding or folding of the hinge mechanism 100.

[0126] An even number of first swing arms 102 can be divided into a plurality of first subgroups, each of which includes two first swing arms 102. The two first swing arms 102 in each first subgroup are symmetrically distributed on both sides of the width direction of the base 101 with respect to the center line S of the base 101. The center line S of the base 101 is parallel to the length direction of the rotating shaft mechanism 100, and the width direction of the base 101 is parallel to the width direction of the rotating shaft mechanism 100. The center line S of the base 101 passes through the midpoint of the width of the base 101. The plurality of first subgroups are distributed along the length direction of the rotating shaft mechanism 100.

[0127] An even number of second swing arms 103 can be divided into a plurality of second subgroups, each second subgroup includes two second swing arms 103, and the two second swing arms 103 in each second subgroup are symmetrically distributed on both sides of the width direction of the base 101 with respect to the center line S of the base 101, the center line S of the base 101 is parallel to the length direction of the rotating shaft mechanism 100, and the width direction of the base 101 is parallel to the width direction of the rotating shaft mechanism 100; the center line S of the base 101 is the axis of the rotating shaft mechanism 100. The plurality of second subgroups are distributed along the length direction of the rotating shaft mechanism 100.

[0128] The other end of the first swing arm 102 is slidably connected to the connecting block 104, and the other end of the second swing arm 103 is hinged to the connecting block 104; the first swing arm 102 is also movably connected to the door panel 105; the second swing arm 103 is movably connected to the door panel 105, and the connecting block 104 is rotatably connected to the door panel 105. It should be noted that the first swing arm 102 can also be called an auxiliary swing arm, and the second swing arm 103 can also be called a main swing arm. The two first swing arms 102 in each first subgroup are respectively connected to different door panels 105, and the two second swing arms 103 in each second subgroup are respectively connected to different door panels 105.

[0129] It should be noted that the first swing arm 102 and the base 101 can be rotatably connected by a hinge; the second swing arm 103 and the base 101 can be rotatably connected by a virtual axis connection, that is, the second swing arm 103 has a curved surface, and the base 101 has a curved surface, and the curved surface of the second swing arm 103 cooperates with the curved surface of the base 101 to realize a virtual axis rotation connection.

[0130] Combination Figure 7 and Figure 8 As shown, Figure 7 for Figure 5 A top view of the rotating shaft mechanism 100 in an unfolded state; Figure 8 For along Figure 7 Sectional view along line DD.

[0131] In some embodiments, a guide assembly may be provided on the first swing arm 102, and the first swing arm 102 and the door panel 105 are movably connected through the guide assembly. In this way, the movement of the first swing arm 102 can drive the door panel 105 to move. The guide assembly may include a first guide member 106, and the first guide member 106 is fixedly connected to the first swing arm 102. When the first swing arm 102 is in the unfolded position relative to the base 101, the door panel 105 can overlap with the first guide member 106 to ensure the movably connected between the first guide member 106 and the door panel 105. For example, as Figure 8 As shown, the door panel 105 is provided with a first slide groove 107, which is curved, and both ends of the first slide groove 107 in the length direction are open, which is conducive to the movement of the first guide member 106 in the first slide groove 107. The first guide member 106 is a columnar structure; since the first swing arm 102 is in the unfolded position relative to the base 101, Figure 8 As can be seen from the figure, the first guide member 106 in a columnar shape is inserted into the first slide groove 107, and the contact form between the first guide member 106 and the first slide groove 107 is a higher pair. The first guide member 106 and the two opposite groove walls of the first slide groove 107 can contact each other, thus ensuring the overlap between the first guide member 106 and the first slide groove 107. The first guide member 106 can move along the length extension direction of the first slide groove 107 under the limitation of the two opposite groove walls of the first slide groove 107, so that the first swing arm 102 and the door panel 105 are in effective connection when the rotating shaft mechanism 100 is in the unfolded state. The first slide groove 107 can be a curved groove with a changing curvature, that is, a non-circular arc groove, or a circular arc groove with a constant curvature. The first slide groove 107 corresponds to only one first guide member 106, so that a first slide groove 107 corresponds to and cooperates with one first guide member 106 to ensure that the first swing arm 102 and the door panel 105 can generate relative movement.

[0132] See also Fig. 9As shown, Fig. 9 For along Figure 7 In some embodiments, the guide assembly may further include a second guide member 108, and the second guide member 108 is fixedly connected to the first swing arm 102. When the first swing arm 102 is in the extended position relative to the base 101, the door panel 105 and the second guide member 108 may overlap or may not overlap. Fig. 9 As shown, the door panel 105 is also provided with a second slide groove 109, and the second guide member 108 can be inserted into the second slide groove 109. One end of the second slide groove 109 in the length direction is in the form of an opening, which ensures that the first swing arm 102 can be in an unfolded state; the other end of the second slide groove 109 in the length direction is in the form of a closed opening, which ensures that when the first swing arm 102 is in a folded state, the second guide member 108 can make the door panel 105 at a required angle. The other end of the second slide groove 109 in the length direction is close to the base 101; the second guide member 108 is a columnar structure, and the second slide groove 109 is curved. Fig. 9 In the embodiment, the columnar second guide member 108 is in contact with only one groove wall of the second slide groove 109, and the contact form between the second guide member 108 and the second slide groove 109 is a high pair. The second guide member 108 is located at one end of the length direction of the second slide groove 109. The second slide groove 109 can be a curved groove with a changing curvature, that is, a non-arc groove, or a circular arc groove with a constant curvature. The second slide groove 109 corresponds to only one second guide member 108, so that a second slide groove 109 corresponds to one second guide member 108 to ensure that the first swing arm 102 and the door panel 105 can generate relative motion.

[0133] Combination Figure 8 and Fig. 9 As shown, a first guide member 106 and a second guide member 108 are fixed to the first swing arm 102. When the first swing arm 102 is in an unfolded position relative to the base 101, due to Fig. 9 The second guide member 108 contacts only one groove wall of the second slide groove 109, and the second guide member 108 may be at risk of being separated from the second slide groove 109. However, the first guide member 106 is limited by two opposite groove walls of the first slide groove 107 when the first swing arm 102 is in the unfolded position relative to the base 101, so that the first swing arm 102 and the door panel 105 are movably connected by the existence of the first guide member 106 when the first swing arm 102 is in the unfolded position relative to the base 101, avoiding the separation between the first swing arm and the door panel, thereby ensuring that the first swing arm can drive the door panel during the folding and unfolding process.

[0134] It should be noted that Fig. 9 The second chute 109 in Figure 8The first sliding grooves 107 are distributed along the length direction of the door panel 105 , and the length direction of the door panel 105 is parallel to the length direction of the rotating shaft mechanism 100 .

[0135] Fig.10 It is a schematic diagram of the partial structure of a form of a rotating shaft mechanism 100 in an embodiment of the present application when the door panel 105 is not installed. Fig.10 The rotating shaft mechanism 100 is in an unfolded state. The two first swing arms 102 are symmetrically arranged about the center line S of the base 101, and the two second swing arms 103 are symmetrically arranged about the center line S of the base 101. In some embodiments, one end of the first guide member 106 is fixedly connected to the first swing arm 102, and the other end of the first guide member 106 can be inserted into the first slide groove 107 of the door panel 105. One end of the second guide member 108 is fixedly connected to the first swing arm 102, and the other end of the second guide member 108 can be inserted into the second slide groove 109 of the door panel 105. One end and the other end of the first guide member 106 are the two opposite ends of the columnar structure, and one end and the other end of the second guide member 108 are also the two opposite ends of the columnar structure. For the columnar structure, its radial cross section can be circular or elliptical. The radial cross section of the columnar structure is perpendicular to the length direction of the columnar structure. The diameter of the radial cross section of the first guide member 106 and the diameter of the radial cross section of the second guide member 108 can be the same or different, and this application does not limit it.

[0136] The connecting block 104 is provided with two limiting grooves 111 arranged opposite to each other, and the first swing arm 102 is provided with first limiting wings 110 on opposite sides in the length direction of the rotating shaft mechanism 100 respectively. The two first limiting wings 110 are arranged in a one-to-one correspondence with the two limiting grooves 111, and the first limiting wings 110 can be inserted into the limiting grooves 111, thereby realizing a sliding connection between the connecting block 104 and the first swing arm 102.

[0137] The second swing arm 103 may be provided with a first pin shaft 112, and the second swing arm 103 may be movably connected to the door panel 105 through the first pin shaft 112. The other end of the second swing arm 103 may be provided with a second pin shaft 113, and the connecting block 104 has a mounting hole 114 that matches the second pin shaft 113, and the second pin shaft 113 may pass through the mounting hole 114 on the connecting block 104 to realize the hinge connection between the other end of the second swing arm 103 and the connecting block 104. The first pin shaft 112 may be located on the side of the entity part between one end of the second swing arm 103 and the other end of the second swing arm 103, that is, the first pin shaft 112 is located on one side surface of the second swing arm in the length direction of the rotating shaft mechanism.

[0138] The connecting block 104 may also have a first slider 115 matched with the door panel 105 to realize the rotational connection between the connecting block 104 and the door panel 105. The first slider 115 may be curved, for example, arc-shaped, to realize the contact between the connecting block 104 and the door panel 105 as a low pair.

[0139] Fig.11 It is a top view of the local structure of the rotating shaft mechanism 100 in the embodiment of the present application when the door panel 105 and the connecting block 104 are not installed. Fig.11 The rotating shaft mechanism 100 is in the unfolded state. In some embodiments, the first swing arm 102 may have a recessed groove 116, and the first guide member 106 and the second guide member 108 may be respectively located on two different groove walls opposite to each other of the recessed groove 116. The direction from one end of the first guide member 106 to the other end opposite to the first guide member 106 is opposite to the direction from one end of the second guide member 108 to the other end opposite to the second guide member 108, so that the first guide member 106 and the second guide member 108 are arranged opposite to each other on the first swing arm 102 to be suitable for different application scenarios. Fig.11 As shown, when the first swing arm 102 is in the unfolded position relative to the base 101, the positional relationship between the first guide member 106 and the second guide member 108 in the width direction of the rotating shaft mechanism 100 is as follows: in the width direction of the rotating shaft mechanism 100, the distance between the first guide member 106 and the center line S of the base 101 is smaller than the distance between the second guide member 108 and the center line S of the base 101, so that when the first swing arm 102 is in the unfolded position relative to the base 101, at least the movable connection between the first guide member 106 and the first slide groove 107 can be ensured. When the first guide member 106 is a regular columnar structure, such as a cylinder or an elliptical cylinder, the distance between the first guide member 106 and the center line S of the base 101 is the distance between the center line of the first guide member and the center line S of the base 101, and similarly, the distance between the second guide member 108 and the center line S of the base 101 is the distance between the center line of the second guide member 108 and the center line S of the base 101.

[0140] See also Fig.11As shown, when the first swing arm 102 is in the unfolded position relative to the base 101, the projection of the first guide member 106 in the setting plane and the projection of the second guide member 108 in the setting plane are spaced apart in the width direction of the rotating shaft mechanism 100. Since the first guide member 106 and the second guide member 108 are spaced apart in the width direction of the rotating shaft mechanism 100, when the first swing arm 102 is in the unfolded position relative to the base 101, the distance between the boundary line of the first guide member 106 in the projection in the setting plane closest to the base 101 and the boundary line of the second guide member 108 in the projection in the setting plane farthest from the base 101 is greater than any one of the first distance and the second distance; the first distance is the width of the projection of the first guide member 106 in the setting plane in the width direction of the rotating shaft mechanism 100, and the second distance is the width of the projection of the second guide member 108 in the setting plane in the width direction of the rotating shaft mechanism 100, the setting plane is perpendicular to the thickness direction of the rotating shaft mechanism 100, and the setting plane is parallel to the width direction of the rotating shaft mechanism 100. In this way, when the first swing arm 102 is in the unfolded position relative to the base 101, the first guide member 106 and the second guide member 108 are spaced apart from each other on the first swing arm 102 in the width direction of the rotating shaft mechanism 100, thereby ensuring that the door panel 105 will not be separated from the first swing arm 102. In one embodiment, when the first guide member 106 and the second guide member 108 are both cylindrical structures, the first distance is the diameter of the cylindrical first guide member 106, and the second distance is the diameter of the cylindrical second guide member 108.

[0141] It should be noted that the set plane is not a unique plane, and it can be any plane that is perpendicular to the thickness direction of the rotating shaft mechanism 100 and parallel to the width direction of the rotating shaft mechanism 100 .

[0142] Fig.12 It is a partial structural schematic diagram of a rotating shaft mechanism 100 in a form of an embodiment of the present application in a semi-expanded state; Fig.13 for Fig.12 FIG. 1 is a top view of the hinge mechanism 100 in a semi-expanded state.

[0143] Fig.14 For along Fig.13 As shown in the figure, when the rotating shaft mechanism 100 is in a semi-expanded state, the first guide member 106 is located in the first sliding groove 107. Figure 8 and Fig.14 It can be seen that as the first swing arm 102 changes from the deployed position to the semi-deployed position, the position of the first guide member 106 in the first sliding groove 107 changes.

[0144] Fig.15 For along Fig.13In some embodiments, since at least a portion of the first guide member 106 is inserted into the first slide slot 107 when the first swing arm 102 is in the deployed position relative to the base 101, the door panel 105 moves under the drive of the first guide member 106 during the transition from the deployed position to the semi-deployed position, thereby gradually causing the end of the second guide member 108 to slide into the second slide slot 109, so that the second guide member 108 is limited by the opposite side walls of the second slide slot 109. Fig. 9 and Fig.15 It can be seen that as the first swing arm 102 changes from the deployed position to the semi-deployed position, the position of the second guide member 108 in the second sliding groove 109 changes.

[0145] Fig.16 It is a schematic diagram of the local structure of a rotating shaft mechanism 100 in an embodiment of the present application in a folded state. Fig.17 for Fig.16 A local enlarged schematic diagram of point H in the middle.

[0146] In some embodiments, the door panel 105 may have a third slide groove 117 that matches the first pin 112 on the second swing arm 103. The third slide groove 117 may be curved so that the second swing arm 103 can also control the movement of the door panel 105. The door panel 105 may also have a fourth slide groove 118 that matches the first slider 115 on the connecting block 104. The fourth slide groove 118 may be curved, and the shape of the fourth slide groove 118 is similar to that of the first slider 115, so as to facilitate the rotational connection between the door panel 105 and the connecting block 104.

[0147] Fig.18 for Fig.16 A partial enlarged schematic diagram at I in the figure. In some embodiments, the door panel 105 may include a panel body 119 and a first slot seat 120, the first slot seat 120 is fixedly connected to the panel body 119, and the first slide groove 107 and the second slide groove 109 are opened on the first slot seat 120. Since the first slot seat 120 cooperates with the first swing arm 102, the number of first slot seats 120 on each door panel 105 is equal to the number of first subgroups. For example, the number of each door panel 105 can be one or more, and the multiple first slot seats are distributed at intervals along the length direction of the door panel. The first slot seat 120 has a first side 121 and a second side 122 opposite to each other, and the direction from the first side 121 to the second side 122 is parallel to the length direction of the panel body 119; the length direction of the panel body 119 is parallel to the length direction of the rotating shaft mechanism 100, and the first slot seat 120 is set on the panel body 119 to facilitate the opening of the first slide groove 107 and the second slide groove 109 that cooperate with the first guide member 106 and the second guide member 108, respectively. Exemplarily, as Fig.18As shown, the first slide groove 107 is located at the first side 121, and the second slide groove 109 is located at the second side 122. The first guide member 106 and the second guide member 108 are arranged opposite to each other, so as to adapt to the first slide groove 107 and the second slide groove 109 located at the first side 121 and the second side 122 respectively. Fig.11 and Fig.17 shown; from Fig.18 It can be seen that one end of the second slide groove 109 in the length direction is open, and the other end of the second slide groove 109 in the length direction is closed. For example, the end of the second slide groove 109 close to the base 101 in the length direction is closed, which makes it easy to control the angle of the door panel when it is in a folded state.

[0148] Fig.19 It is a partial structural schematic diagram of the hinge mechanism 100 in a folded state from another perspective in the embodiment of the present application. Fig. 20 for Fig.19 The partial enlarged schematic diagram of the J in the middle. It can be seen that both ends of the first chute 107 in the length direction are in the form of openings.

[0149] Fig.21 1 is a top view of the hinge mechanism 100 in a folded state in the embodiment of the present application. Fig. 22 For along Fig.21 As shown in the figure, the first slider 115 on the connecting block 104 is located in the fourth slide groove 118 to achieve the rotation connection between the connecting block 104 and the door panel 105. The cooperation between the first slider 115 on the connecting block 104 and the fourth slide groove 118 can control the rotation center of the door panel 105.

[0150] Fig.23 For along Fig.21 As shown in the figure, the end of the first pin 112 installed on the second swing arm 103 is inserted into the third slide groove 117, so that when the second swing arm 103 rotates relative to the base 101, the door panel 105 can also be controlled by the second swing arm 103, and the door panel 105 moves with the second swing arm 103, thereby realizing precise control of the rotation angle of the door panel 105, and making the door panel 105 move more smoothly, preventing the door panel 105 from slipping out between the first swing arm 102 when the hinge mechanism 100 is in the unfolded state.

[0151] Fig.24 For along Fig.21 In some embodiments, when the first swing arm 102 is in the folded position relative to the base 101, the first guide member 106 and the first slide groove 107 are no longer overlapped, and the first guide member 106 is disengaged from the first slide groove 107. Figure 8 , Fig.14 and Fig.24It can be seen that after the hinge mechanism 100 changes from the unfolded state to the semi-expanded state and then from the semi-expanded state to the folded state, the position of the first guide member 106 in the first slide groove 107 changes, from the end of the first guide member 106 being located in the first slide groove 107 to the end of the first guide member 106 being disengaged from the first slide groove 107.

[0152] Fig.25 For along Fig.21 In some embodiments, when the first swing arm 102 is in the folded position relative to the base 101, the end of the second guide member 108 is inserted into the second slide slot 109, and the second guide member 108 is located at the other end of the second slide slot 109 in the length direction, that is, the end of the second guide member 108 is located at the end of the second slide slot 109 in the closed form, thereby limiting the movement angle of the door panel 105 relative to the first swing arm 102, thereby achieving the control of the rotation angle of the door panel 105. Fig. 9 , Fig.15 and Fig.25 , it can be seen that after the rotating shaft mechanism 100 changes from the unfolded state to the semi-expanded state and then from the semi-expanded state to the folded state, the position of the second guide member 108 in the second slide groove 109 changes from the end of the second guide member 108 contacting the groove wall on one side of the second slide groove 109 to the end of the second guide member 108 being limited by the groove walls on the opposite sides of the second slide groove 109. In this way, although the first swing arm 102 is in the folded position relative to the base 101, the first guide member 106 is disengaged from the first slide groove 107 (see Fig.24 As shown), but the second guide member 108 is in contact with the second slide groove 109 (see Fig.25 As shown), the door panel 105 and the second guide member 108 are overlapped.

[0153] Please combine Figure 8 and Fig.25As shown, it can be known that a form of the rotating shaft mechanism 100 provided in the embodiment of the present application can be applied to the application scenario when the width of the shaft cover is relatively wide and the width of the door panel 105 is relatively narrow. In this scenario, the first guide member 106 and the second guide member 108 are arranged on the first swing arm 102 so as to achieve overlapping with the door panel 105 in an alternating manner, thereby ensuring that when the first swing arm 102 switches between the unfolded position and the folded position, the first swing arm 102 and the door panel 105 always maintain an effective active connection, and the movement of the door panel 105 can be accurately controlled. Among them, the first slide groove 107 and the second slide groove 109 of the first swing arm 102 are used to control the movement angle of the door panel 105. The addition of the second guide member 108 can replace the first guide member 106 when the pivot mechanism 100 is close to the unfolded state, and continue to accurately control the movement of the door panel 105. Therefore, the first guide member 106 and the second guide member 108 on the first swing arm 102 can ensure that the first swing arm 102 and the door panel 105 will not be separated, and can be applied to the pivot mechanism 100 with a narrower door panel 105 design.

[0154] Fig.26 A schematic diagram of the partial structure of another form of a rotating shaft mechanism 100 in an expanded state provided in an embodiment of the present application. Fig. 27 for Fig.26 In some other embodiments, the first slide groove 107 and the second slide groove 109 are located on the same side of the first groove seat 120. Fig. 27 As shown, the first slide groove 107 and the second slide groove 109 are both located on the second side 122. When the rotating shaft mechanism 100 is in the unfolded state, the thickness direction of the plate body 119 is parallel to the thickness direction of the rotating shaft mechanism 100, and the first slide groove 107 and the second slide groove 109 are spaced apart in the thickness direction of the rotating shaft mechanism 100. The first slide groove 107 can be located below the second slide groove 109, that is, the first slide groove 107 can be closer to the base 101 compared with the second slide groove 109. In this way, the space in the thickness direction of the rotating shaft mechanism 100 can be fully utilized, and the space utilization rate in the thickness direction of the rotating shaft mechanism 100 can be improved. Furthermore, both ends of the first slide groove 107 in the length direction can be in the form of openings, and one end of the second slide groove 109 in the length direction can be in the form of closing.

[0155] It should be noted that, in some other possible implementations, the first slide groove 107 and the second slide groove 109 may also be both located on the first side 121 , and the first slide groove 107 and the second slide groove 109 are spaced apart in the thickness direction of the plate body 119 .

[0156] Fig.28 for Fig.26 FIG. 1 is a top view of another type of rotating shaft mechanism 100 in an unfolded state. Fig.29 For along Fig.28 Cross-sectional view along line OO in the figure. In other embodiments, when the first swing arm 102 is in the unfolded position relative to the base 101, the end of the first guide member 106 is located in the first slide slot 107, and the first guide member 106 is limited by the slot walls on opposite sides of the first slide slot 107. The end of the second guide member 108 contacts the slot wall on one side of the second slide slot 109. However, since the first guide member 106 is located in the first slide slot 107, the movable connection between the first swing arm 102 and the door panel 105 can be ensured, thereby preventing the first swing arm 102 and the door panel 105 from being separated.

Fig.31The pivot mechanism 100 is in the expanded state. In some other embodiments, the first swing arm 102 has a recessed groove 116, and the first guide member 106 and the second guide member 108 are respectively located on the groove wall on the same side of the recessed groove 116, and the direction from one end of the first guide member 106 to the other end opposite to the first guide member 106 is the same as the direction from one end of the second guide member 108 to the other end opposite to the second guide member 108, so that the first guide member 106 and the second guide member 108 are arranged in the same direction on the first swing arm 102, which is beneficial to improve the utilization rate of the thickness direction of the pivot mechanism 100. The first guide member 106 and the second guide member 108 are arranged in the same direction to adapt to the first slide groove 107 and the second slide groove 109 both located on the second side 122 of the first groove seat 120 of the door panel 105. Please refer to FIG. Fig. 27 and Fig.31 As shown. Fig.31 As shown, when the first swing arm 102 is in the expanded position relative to the base 101, the positional relationship between the first guide member 106 and the second guide member 108 in the width direction of the rotating shaft mechanism 100 is: the first guide member 106 is close to the base 101, and the second guide member 108 is far away from the base 101, that is, in the width direction of the rotating shaft mechanism 100, the distance between the first guide member 106 and the base 101 is smaller than the distance between the second guide member 108 and the base 101, specifically: the distance between the first guide member 106 and the center line S of the base 101 is smaller than the distance between the second guide member 108 and the center line S of the base 101, so that when the first swing arm 102 is in the expanded position relative to the base 101, at least it is ensured that the first guide member 106 is still movably connected with the first slide groove 107.

Since the first guide member 106 and the second guide member 108 are spaced apart in the width direction of the rotating shaft mechanism 100, when the first swing arm 102 is in the unfolded position relative to the base 101, the distance between the boundary line of the first guide member 106 in the projection in the setting plane closest to the base 101 and the boundary line of the second guide member 108 in the projection in the setting plane farthest from the base 101 is greater than any one of the first distance and the second distance; the first distance is the width of the projection of the first guide member 106 in the setting plane in the width direction of the rotating shaft mechanism 100, and the second distance is the width of the projection of the second guide member 108 in the setting plane in the width direction of the rotating shaft mechanism 100, the setting plane is perpendicular to the thickness direction of the rotating shaft mechanism 100, and the setting plane is parallel to the width direction of the rotating shaft mechanism 100. In this way, when the first swing arm 102 is in the unfolded position relative to the base 101, the first guide member 106 and the second guide member 108 are spaced apart from each other on the first swing arm 102 in the width direction of the rotating shaft mechanism 100, thereby ensuring that the door panel 105 and the first swing arm 102 will not be separated. In one embodiment, when the first guide member 106 and the second guide member 108 are both cylindrical structures, the first distance is the diameter of the cylindrical first guide member 106, and the second distance is the diameter of the cylindrical second guide member 108. It should be noted that the setting plane is not a single plane, and it can be any plane that is perpendicular to the thickness direction of the rotating shaft mechanism 100 and parallel to the width direction of the rotating shaft mechanism 100.
