Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a pivot mechanism and a foldable electronic device. Background Technology

[0002] With the development of technology, electronic devices such as mobile phones, tablets, and laptops have become increasingly common. As user demands have increased, foldable screen electronic devices have emerged to balance users' need for large screens with the portability of electronic devices.

[0003] Foldable electronic devices utilize a flexible display screen and a hinge mechanism to enable 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 portion of the flexible display screen to form a teardrop angle; when the hinge mechanism is in the unfolded state, the door panel supports the foldable portion of the flexible display screen to assist in flattening the foldable portion of the flexible display screen.

[0004] The pivot mechanism also includes a pivot cover, a base, a connecting block, and a swing arm. The base is fixedly connected to the pivot cover, and the swing arm is rotatably connected to the base. The swing arm and connecting block control the movement of the door panel. Typically, the door panel has an arc-shaped groove, and the pin at the end of the swing arm is inserted into the arc-shaped groove. During the unfolding and folding of the pivot mechanism, the pin remains in the arc-shaped groove. However, in cases where the pivot cover is wider and the door panel is narrower, the length of the arc-shaped groove becomes shorter due to the narrower door panel, but the travel distance of the pin at the end of the swing arm remains unchanged. This can cause the pin to disengage from the arc-shaped groove during the unfolding and folding of the pivot mechanism, resulting in the swing arm detaching from the door panel and affecting the user experience. Summary of the Invention

[0005] This application provides a pivot mechanism and a foldable electronic device to solve the technical problem that the pin on the swing arm will disengage 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] The first aspect of this application provides a pivot 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 relative to the base between an unfolded position and a folded position. A guide assembly is provided on the first swing arm. 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 via the guide assembly;

[0010] Specifically, 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 solution, this application utilizes a first guide and a second guide on the first swing arm to achieve alternating contact with the door panel, thereby ensuring that the first swing arm and the door panel always maintain an effective movable connection when the first swing arm is switched between the unfolded position and the folded position.

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

[0013] By adopting the above scheme, when the first swing arm is in the unfolded position relative to the base, the relative positions of the first guide and the second guide on the first swing arm are defined, so that the overlap between the first guide and the door panel can be connected to the overlap between the second guide and the door panel. This ensures that the door panel and the first swing arm will not separate when the first swing arm is switched between the unfolded 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 unfolded position relative to the base, the distance between the boundary line closest to the base in the projection of the first guide member in the set plane and the boundary line farthest from the base in the projection of the second guide member in the set plane is greater than either a first distance or a second distance.

[0015] The first distance is the width of the projection of the first guide member onto the set 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 onto the set 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 unfolded position relative to the base, the first guide and the second guide are misaligned on the first swing arm in the width direction of the rotating shaft mechanism. This allows the first guide and the second guide to be connected to the door panel respectively, so as to ensure that the door panel and the first swing arm will not detach.

[0018] In some implementations, when the first swing arm is in the unfolded position relative to the base, the projections of the first guide member in a set plane and the projections of the second guide member in the set plane are spaced apart in the 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 unfolded position relative to the base, the first guide and the second guide are spaced apart 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 detach.

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

[0024] By adopting the above scheme, the first guide and the second guide are inserted into their respective sliding grooves, thus ensuring that the door panel and the first swing arm will not separate when the first swing arm moves.

[0025] In some implementations, the door panel includes a panel body and a first groove seat, the first groove seat being fixedly connected to the panel body, and the first sliding groove and the second sliding groove being formed on the first groove 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 scheme, a first groove seat is provided on the plate body to facilitate the opening of a first slide groove and a second slide groove that respectively cooperate with the first guide member and the second guide member.

[0028] In some implementations, the first slot has opposing first and second sides, and the direction from the first side to the second side is parallel to the length direction of the plate body; wherein,

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

[0030] Alternatively, both the first and second slide grooves are located on the first side, and the first and second slide grooves are distributed at intervals in the thickness direction of the plate body;

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

[0032] By adopting the above scheme, the first slide rail and the second slide rail are respectively set on opposite sides of the first slot seat, or the first slide rail and the second slide rail are set on either side of the first slot seat at the same time to adapt to different application occasions, so as to ensure the accuracy of controlling the movement of the door panel.

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

[0034] By adopting the above scheme, the first and second slide rails are made to be curved, so that the door panel can move with the first swing arm.

[0035] In some embodiments, the two ends of the first chute along its length are open, and one end of the second chute along its length is closed.

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

[0037] In some implementations, the first groove corresponds to a first guide member; the second groove corresponds to a second guide member.

[0038] By adopting the above scheme, the first slide groove is a non-circular arc groove, and the second slide groove is a non-circular arc groove. When the first slide groove cooperates with two or more first guide members, and the second slide groove cooperates with two or more second guide members, the movement of any two first guide members will cause interference, and the movement of any two second guide members will cause interference. In this way, the door panel and the swing arm will not produce the preset movement pattern. Therefore, by having the first slide groove cooperate with only one first guide member and the second slide groove cooperate with only one second guide member, the relative movement between the swing arm and the door panel is guaranteed to meet the design requirements.

[0039] In some implementations, both the first guide member and the second guide member are 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 can be inserted into the first slide groove;

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

[0042] By adopting the above scheme, 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, the direction from one end of the first guide member to the opposite end of the first guide member is the same as the direction from one end of the second guide member to the opposite end of the second guide member;

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

[0045] By adopting the above scheme, 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 and the second guide are respectively located on two different groove walls opposite to the recessed groove; or, the first guide and the second guide are respectively located on the groove wall on the same side of the recessed groove.

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

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

[0050] By adopting the above scheme, it is beneficial to realize the movement of the first guide member and the second guide member in their respective slides, and it is also beneficial to reduce friction and improve the service life of the rotating shaft mechanism.

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

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

[0053] In some implementations, the rotating shaft mechanism further includes a second swing arm, which is rotatably connected to the base and is capable of rotating relative to the base between the unfolded position and the folded position.

[0054] The door panel has a third sliding groove, and the second swing arm is equipped with a first pin, which is inserted into the third sliding groove.

[0055] By adopting the above scheme, the second swing arm and the door panel are connected by the first pin and the third slide groove. In this way, after the first swing arm and the second swing arm are connected, the movement of the door panel can be better controlled and the stability of the door panel movement can be guaranteed.

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

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

[0058] In some implementations, the door panel has a curved fourth slide groove, and the connecting block is fixed with a first slider that cooperates with the fourth slide groove, the first slider being able to move in the fourth slide groove.

[0059] By adopting the above scheme, the fourth sliding groove and the first slider are used to cooperate between the connecting block and the door panel to achieve a low-pair 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 both the first slide groove and the second slide groove are located on the first side of the first slot seat, the second side has a curved fifth slide groove, and the connecting block is provided with a second slider that cooperates with the fifth slide groove;

[0061] Alternatively, when both the first slide groove and the second slide groove are located on the second side of the first slot seat, the first side has a curved fifth slide groove, and the connecting block is provided with a second slider that cooperates with the fifth slide groove.

[0062] By adopting the above scheme, the movement of the door panel can be further precisely controlled through the cooperation of the fifth slide groove and the second slider.

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

[0064] By adopting the above scheme, it is beneficial to make the second slider move in the fifth groove.

[0065] A second aspect of this application provides a foldable electronic device, which includes a first sub-shell, a second sub-shell, and either of the aforementioned pivot mechanisms. The first sub-shell and the second sub-shell are respectively connected to the pivot mechanism, and the first sub-shell and the second sub-shell are rotatable relative to each other through the pivot mechanism.

[0066] By adopting the above scheme, after the pivot mechanism is applied to electronic devices, by setting a first guide and a second guide on the first swing arm so that it can be alternately connected with the door panel, it can be ensured that the first swing arm and the door panel always maintain an effective movable connection when the first swing arm is switched between the unfolded position and the folded position.

[0108] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0109] It should be understood that "multiple" as mentioned in this application refers to two or more. In the description of this application, unless otherwise stated, " / " indicates "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist, for example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., do not necessarily imply differences.

[0110] The rotating shaft mechanism and electronic device provided in the embodiments of this application will be explained in detail below.

[0111] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the electronic device provided in the embodiment of this application in a folded state. Figure 2 This is a schematic diagram of the electronic device provided in the embodiments of this application in a semi-deployed state. Figure 3 This is a schematic diagram of the electronic device provided in the embodiment of this application in its unfolded state.

[0112] In one or more embodiments, this application provides an electronic device, which can be a foldable electronic device. The electronic device includes a housing and a hinge mechanism 100. The housing includes a first sub-housing 301 and a second sub-housing 302, which are respectively connected to the hinge mechanism 100. The first sub-housing 301 and the second sub-housing 302 can rotate relative to each other through the hinge mechanism 100. Exemplary electronic devices can be mobile phones, tablets, laptops, or e-readers. Foldable electronic devices are not limited to electronic devices with foldable displays, such as mobile phones, but can also be electronic devices where the display and keyboard can be folded or unfolded, such as laptops.

[0113] In this embodiment, taking a mobile phone as an example, the electronic device further includes a display screen 200, which can be a flexible display screen. The display screen 200 is connected to a first sub-shell 301 and a second sub-shell 302. The first sub-shell 301 and the second sub-shell 302 can include the mid-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 as the AA direction, and the thickness direction as the CC direction. The AA, BB, and CC directions are mutually perpendicular, forming a Cartesian coordinate system.

[0115] Figure 1 The foldable electronic device shown is in a folded state. Figure 2 The foldable electronic device shown is in a semi-open state. Figure 3 The foldable electronic device shown is in its 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 shown 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-unfolded state, the hinge mechanism 100 is also in the semi-unfolded 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 this application are allowed to have slight deviations. For example, 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. This means that β can be 180 degrees, or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees. The angles illustrated in the following text can be understood in the same way.

[0117] Please see Figure 4 , Figure 4 yes Figure 3 The diagram shows the exploded structure of the electronic device. Figure 4The diagram only illustrates the location of the pivot mechanism 100, but does not limit the specific structural form of the pivot mechanism 100. The first sub-shell 301 and the second sub-shell 302 are respectively installed on both sides of the pivot mechanism 100 along the BB direction. 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, such as an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MOLED) display screen, a micro-organic light-emitting diode (Microorganic Light-emitting Diode) display screen, a quantum dot light-emitting diode (QLED) display screen, etc.

[0118] The foldable electronic device folds by bringing the first sub-shell 301 and the second sub-shell 302 closer together. When the foldable electronic device is in the folded state, the foldable portion 330 of the display screen 200 bends, and the first portion 201 and the second portion 202 are positioned opposite each other. At this time, the display screen 200 is located between the first sub-shell 301 and the second sub-shell 302, which greatly reduces the probability of damage to the display screen 200 and achieves effective protection for the display screen 200.

[0119] Please refer to the following: Figure 2 and Figure 4 The first sub-shell 301 and the second sub-shell 302 rotate relative to each other via the pivot mechanism 100. The relative movement of the first sub-shell 301 and the second sub-shell 302 causes the display screen 200 to unfold, thus unfolding the foldable electronic device to a semi-unfolded state. When the foldable electronic device is in the semi-unfolded state, the first sub-shell 301 and the second sub-shell 302 unfold to an angle α, with the first part 201 and the second part 202 unfolding relative to each other, causing 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 refer to the following: Figure 3 and Figure 4The first sub-shell 301 and the second sub-shell 302 rotate relative to each other via the pivot mechanism 100. As the first sub-shell 301 and the second sub-shell 302 move further apart, the display screen 200 is further unfolded until the foldable electronic device is flattened. The pivot mechanism 100 may have a damping mechanism to achieve a smooth opening and closing feel and maintain the state during rotation.

[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 unfolds, and the first portion 201 and the second portion 202 unfold relative to each other. At this time, the angle between the first portion 201, the second portion 202, and the foldable portion 203 is all β, and the display screen 200 has a large display area, realizing a large-screen display for the foldable electronic device and improving the user experience.

[0122] It should be noted that both included angle α and included angle β are the included angles between the first sub-shell 301 and the second sub-shell 302. These are used here only 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. Specifically, included 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 its semi-open state; included 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 its open state.

[0123] See Figure 5 and Figure 6 As shown, Figure 5 This is a partial structural diagram of a rotating shaft mechanism 100 in an unfolded state, as provided in an embodiment of this application. Figure 6 for Figure 5 Another structural schematic diagram of the rotating shaft mechanism 100 in its unfolded state.

[0124] In some embodiments, the pivot mechanism 100 includes a base 101, a first swing arm 102, a second swing arm 103, a connecting block 104, a door panel 105, and a shaft cover (not shown). The shaft cover can be fixedly connected to the base 101, for example, by screws, or the shaft cover and 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 unfolded 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. In the unfolded state, both the first swing arm 102 and the second swing arm 103 are in the unfolded position relative to the base 101. Figure 6Only a portion of the first swing arm 102 and the second swing arm 103 are shown in the figure.

[0125] In some embodiments, the number of door panels 105 is multiple. The number of first swing arms 102 can be even, and the number of second swing arms 103 can be even. The door panels 105 are used to support the foldable portion 203 of the display screen 200 (which can be combined with...). Figure 4 and Figure 5 (As shown). The rotating shaft 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, thereby realizing the unfolding or folding of the rotating shaft mechanism 100.

[0126] An even number of first swing arms 102 can be divided into multiple first subgroups. Each first subgroup 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 about 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 multiple 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 multiple second subgroups. Each second subgroup includes two second swing arms 103. The two second swing arms 103 in each second subgroup are symmetrically distributed on both sides of the width direction of the base 101 about 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 multiple 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 a secondary swing arm, and the second swing arm 103 can also be called a primary swing arm. The two first swing arms 102 in each first subgroup are connected to different door panels 105, and the two second swing arms 103 in each second subgroup are 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 an arc surface, the base 101 has an arc surface, and the arc surface of the second swing arm 103 and the arc surface of the base 101 cooperate to achieve a virtual axis rotatable connection.

[0130] Combination Figure 7 and Figure 8 As shown, Figure 7 for Figure 5 Top view of the rotating shaft mechanism 100 in its unfolded state; Figure 8 For along Figure 7 A cross-sectional view of the DD line.

[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. Thus, the movement of the first swing arm 102 can cause the door panel 105 to move accordingly. The guide assembly may include a first guide member 106, which 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 can overlap with the first guide member 106 to ensure a movable connection between the first guide member 106 and the door panel 105. For example, as shown... Figure 8 As shown, a first sliding groove 107 is provided on the door panel 105. The first sliding groove 107 is curved, and both ends of the first sliding groove 107 are open along its length, which facilitates the movement of the first guide member 106 within the first sliding groove 107. The first guide member 106 has a columnar structure; since the first swing arm 102 is in the extended position relative to the base 101, it can move from... Figure 8 As can be seen, the columnar first guide member 106 is inserted into the first slide groove 107. The contact form between the first guide member 106 and the first slide groove 107 is a higher pair, meaning that the two opposite walls of the first guide member 106 and 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 of the first slide groove 107, constrained by the two opposite walls of the first slide groove 107, thereby ensuring an effective connection between the first swing arm 102 and the door panel 105 in the unfolded state of the pivot mechanism 100. The first slide groove 107 can be a curved groove with varying curvature, i.e., a non-circular arc groove, or a circular arc groove with constant curvature. Each first slide groove 107 corresponds to only one first guide member 106, ensuring relative movement between the first swing arm 102 and the door panel 105.

[0132] See Figure 9As shown, Figure 9 For along Figure 7 A cross-sectional view along the EE line. In some embodiments, the guide assembly may further include a second guide 108, which 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 108 may overlap, or they may not overlap. For example, as... Figure 9 As shown, a second sliding groove 109 is also provided on the door panel 105. The second guide member 108 can be inserted into the second sliding groove 109. One end of the second sliding groove 109 is open along its length, ensuring that the first swing arm 102 can be in the unfolded state; the other end of the second sliding groove 109 is closed, ensuring that when the first swing arm 102 is in the folded state, the second guide member 108 can position the door panel 105 at the required angle. The other end of the second sliding groove 109 is close to the base 101; the second guide member 108 has a columnar structure, and the second sliding groove 109 is curved. Figure 9 In this configuration, the columnar second guide member 108 contacts only one wall of the second slide groove 109. The contact between the second guide member 108 and the second slide groove 109 is a high-pair configuration, with the second guide member 108 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 varying curvature, i.e., a non-circular arc groove, or a circular arc groove with constant curvature. Each second slide groove 109 corresponds to only one second guide member 108, ensuring relative movement between the first swing arm 102 and the door panel 105.

[0133] Combination Figure 8 and Figure 9 As shown, a first guide member 106 and a second guide member 108 are fixed on the first swing arm 102. When the first swing arm 102 is in the extended position relative to the base 101, due to... Figure 9 The second guide 108 contacts only one wall of the second slide groove 109, and there is a risk that the second guide 108 may detach from the second slide groove 109. However, the first guide 106 is limited by the two opposite walls of the first slide groove 107 when the first swing arm 102 is in the unfolded position relative to the base 101. In this way, the presence of the first guide 106 ensures that the first swing arm 102 is movably connected to the door panel 105 when the first swing arm 102 is in the unfolded position relative to the base 101, avoiding the situation where the first swing arm detaches from the door panel, and thus ensuring that the first swing arm can drive the door panel during folding and unfolding.

[0134] It should be noted that, Figure 9 The second groove 109 in the middle and Figure 8The first groove 107 is 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] Figure 10 This is a partial structural diagram of a rotating shaft mechanism 100 in one embodiment of this application without the door panel 105 installed. Figure 10 The pivot mechanism 100 is in the deployed state. Two first swing arms 102 are symmetrically arranged about the center line S of the base 101, and 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 106 is fixedly connected to the first swing arm 102, and the other end of the first guide 106 can be inserted into the first slide groove 107 of the door panel 105. One end of the second guide 108 is fixedly connected to the first swing arm 102, and the other end of the second guide 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 106 are the two opposite ends of the columnar structure, and one end and the other end of the second guide 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 106 and the diameter of the radial cross-section of the second guide 108 can be the same or different; this application does not impose any limitation.

[0136] The connecting block 104 has two limiting grooves 111 that are arranged opposite to each other. The first swing arm 102 has first limiting wings 110 on opposite sides of the rotating shaft mechanism 100 along the length direction. The two first limiting wings 110 are arranged in a one-to-one correspondence with the two limiting grooves 111. The first limiting wings 110 can be inserted into the limiting grooves 111, thus realizing the 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 112, and the second swing arm 103 may be movably connected to the door panel 105 via the first pin 112. The other end of the second swing arm 103 may be provided with a second pin 113, and the connecting block 104 has a mounting hole 114 that mates with the second pin 113. The second pin 113 may pass through the mounting hole 114 on the connecting block 104 to achieve hinge connection between the other end of the second swing arm 103 and the connecting block 104. The first pin 112 may be located on the side of the solid portion between one end and the other end of the second swing arm 103, that is, the first pin 112 is located on one side of the second swing arm along the length direction of the rotating shaft mechanism.

[0138] The connecting block 104 may also have a first slider 115 that cooperates with the door panel 105 to achieve a rotatable connection between the connecting block 104 and the door panel 105. The first slider 115 may be curved, for example, it may be arc-shaped, so that the contact form between the connecting block 104 and the door panel 105 is a low pair.

[0139] Figure 11 This is a partial top view of the rotating shaft mechanism 100 in this embodiment of the application without the door panel 105 and connecting block 104 installed. Figure 11 The pivot mechanism 100 is in an extended state. In some embodiments, the first swing arm 102 may have a recessed groove 116, and the first guide 106 and the second guide 108 may be located on two different opposite groove walls of the recessed groove 116. The direction from one end of the first guide 106 to its opposite end is opposite to the direction from one end of the second guide 108 to its opposite end, so that the first guide 106 and the second guide 108 are arranged opposite each other on the first swing arm 102 to suit different application scenarios. Figure 11 As shown, when the first swing arm 102 is in the extended 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 less than the distance between the second guide member 108 and the center line S of the base 101. This ensures at least a movable connection between the first guide member 106 and the first slide groove 107 when the first swing arm 102 is in the extended position relative to the base 101. When the first guide member 106 is a regular columnar structure, such as a cylinder or 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. 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 Figure 11As shown, when the first swing arm 102 is in the extended position relative to the base 101, the projections of the first guide member 106 and the second guide member 108 in the set 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 extended position relative to the base 101, the distance between the boundary line closest to the base 101 in the projection of the first guide member 106 in the set plane and the boundary line farthest from the base 101 in the projection of the second guide member 108 in the set plane is greater than either the first distance or the second distance. The first distance is the width of the projection of the first guide member 106 in the set 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 set plane in the width direction of the rotating shaft mechanism 100. The set plane is perpendicular to the thickness direction of the rotating shaft mechanism 100 and parallel to the width direction of the rotating shaft mechanism 100. In this way, when the first swing arm 102 is in the extended position relative to the base 101, the first guide member 106 and the second guide member 108 are spaced apart relative to each other on the first swing arm 102 in the width direction of the pivot mechanism 100, thereby ensuring that the door panel 105 does not detach from the first swing arm 102. In one embodiment, when both the first guide member 106 and the second guide member 108 are 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 single plane; 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] Figure 12 This is a partial structural diagram of a rotating shaft mechanism 100 in a semi-expanded state, as described in one embodiment of this application. Figure 13 for Figure 12 A top view of the rotating shaft mechanism 100 in a semi-expanded state.

[0143] Figure 14 For along Figure 13 A cross-sectional view along the FF line. As shown, when the rotating shaft mechanism 100 is in a semi-expanded state, the first guide member 106 is located in the first slide groove 107. (Comparison) Figure 8 and Figure 14 It can be seen that as the first swing arm 102 changes from the extended position to the semi-extended position, the position of the first guide member 106 in the first slide groove 107 changes.

[0144] Figure 15 For along Figure 13A cross-sectional view along line GG. In some embodiments, since at least a portion of the first guide 106 is inserted into the first groove 107 when the first swing arm 102 is in the extended position relative to the base 101, during the transition of the first swing arm 102 from the extended position to the semi-extended position, the door panel 105 moves under the action of the first guide 106, thereby gradually causing the end of the second guide 108 to slide into the second groove 109, so that the second guide 108 is defined by the opposing side walls of the second groove 109. (Comparison) Figure 9 and Figure 15 It can be seen that as the first swing arm 102 changes from the extended position to the semi-extended position, the position of the second guide 108 in the second slide groove 109 changes.

[0145] Figure 16 This is a partial structural diagram of a rotating shaft mechanism 100 in a folded state, as described in one embodiment of this application. Figure 17 for Figure 16 A magnified view of a portion of point H in the middle.

[0146] In some embodiments, the door panel 105 may have a third slide groove 117 that engages with 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 engages with 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 the shape of the first slider 115, so as to facilitate a rotatable connection between the door panel 105 and the connecting block 104.

[0147] Figure 18 for Figure 16 A partially enlarged schematic diagram at point I. In some embodiments, the door panel 105 may include a panel body 119 and a first groove seat 120. The first groove seat 120 is fixedly connected to the panel body 119, and a first sliding groove 107 and a second sliding groove 109 are formed on the first groove seat 120. Since the first groove seat 120 cooperates with the first swing arm 102, the number of first groove seats 120 on each door panel 105 is equal to the number of the first subgroup. For example, each door panel 105 may have one or more, and the multiple first groove seats are spaced apart along the length direction of the door panel. The first groove seat 120 has opposing first sides 121 and second sides 122, 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. The first groove seat 120 is provided on the panel body 119 to facilitate the formation of first sliding grooves 107 and second sliding grooves 109 that respectively cooperate with the first guide member 106 and the second guide member 108. For example, as shown in the figure... Figure 18As shown, the first slide groove 107 is located on the first side 121, and the second slide groove 109 is located on the second side 122. The first guide member 106 and the second guide member 108 are arranged opposite to each other to fit the first slide groove 107 and the second slide groove 109 located on the first side 121 and the second side 122, respectively. Please refer to... Figure 11 and Figure 17 As shown; from Figure 18 As can be seen, 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 near the base 101 in the length direction is closed, which makes it easier to control the angle of the door panel when it is in the folded state.

[0148] Figure 19 This is a partial structural schematic diagram of the rotating shaft mechanism 100 in a folded state from another perspective in an embodiment of this application. Figure 20 for Figure 19 A magnified view of a portion of point J. It can be seen that both ends of the first groove 107 are open along its length.

[0149] Figure 21 This is a top view of the rotating shaft mechanism 100 in a folded state in an embodiment of this application. Figure 22 For along Figure 21 A cross-sectional view along line KK. As shown in the figure, the first slider 115 on the connecting block 104 is located in the fourth slide groove 118 to achieve a rotational connection between the connecting block 104 and the door panel 105. The cooperation between the curved 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] Figure 23 For along Figure 21 A cross-sectional view along the RR line. As shown in the figure, the end of the first pin 112 mounted on the second swing arm 103 is inserted into the third slide groove 117. 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. The door panel 105 moves with the second swing arm 103, thereby achieving precise control of the rotation angle of the door panel 105 and making the movement of the door panel 105 smoother, preventing the door panel 105 from dislodging from the first swing arm 102 when the rotating shaft mechanism 100 is in the unfolded state.

[0151] Figure 24 For along Figure 21 A cross-sectional view along line LL. In some embodiments, when the first swing arm 102 is in the folded position relative to the base 101, the first guide 106 no longer overlaps with the first slide groove 107, and the first guide 106 disengages from the first slide groove 107. And combined Figure 8 , Figure 14 and Figure 24As can be seen, after the rotating shaft mechanism 100 changes from the unfolded state to the semi-unfolded state and then from the semi-unfolded 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] Figure 25 For along Figure 21 A cross-sectional view along the MM line. 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 groove 109. The second guide member 108 is located at the other end of the length direction of the second slide groove 109, that is, the end of the second guide member 108 is located at the closed end of the second slide groove 109. This limits the movement angle of the door panel 105 relative to the first swing arm 102, thereby controlling the rotation angle of the door panel 105. And combined with... Figure 9 , Figure 15 and Figure 25 It can be seen that after the rotating shaft mechanism 100 changes from the unfolded state to the semi-unfolded state, and then from the semi-unfolded state to the folded state, the position of the second guide member 108 in the second slide groove 109 changes. Previously, the end of the second guide member 108 was in contact with one side of the slide groove 109; now, the end of the second guide member 108 is limited by the opposite sides of the slide groove 109. Thus, although the first guide member 106 is disengaged from the first slide groove 107 when the first swing arm 102 is in the folded position relative to the base 101 (see...), the position of the second guide member 108 changes. Figure 24 (as shown), but the second guide 108 is in contact with the second slide groove 109 (see...). Figure 25 As shown in the figure, this achieves the overlap between the door panel 105 and the second guide member 108.

[0153] Please combine Figure 8 and Figure 25As shown, the rotating shaft mechanism 100 provided in this embodiment can be applied to scenarios where the width of the shaft cover is relatively wide, while the width of the door panel 105 is relatively narrow. In this scenario, by using a first guide 106 and a second guide 108 on the first swing arm 102, it is possible to alternately connect with the door panel 105. This ensures that when the first swing arm 102 switches between the unfolded and folded positions, the first swing arm 102 and the door panel 105 maintain an effective movable connection, and the movement of the door panel 105 can be precisely controlled. 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 separate. This can be applied to the pivot mechanism 100 with a narrower door panel 105 design.

[0154] Figure 26 A partial structural schematic diagram of another form of rotating shaft mechanism 100 provided in the embodiments of this application in an unfolded state. Figure 27 for Figure 26 A partially enlarged schematic diagram at point N. In other embodiments, the first groove 107 and the second groove 109 are located on the same side of the first groove seat 120. For example, as Figure 27 As shown, both the first slide groove 107 and the second slide groove 109 are 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 along the thickness direction of the rotating shaft mechanism 100. The first slide groove 107 can be located below the second slide groove 109, meaning that the first slide groove 107 can be closer to the base 101 than the second slide groove 109. This fully utilizes the space along the thickness direction of the rotating shaft mechanism 100, improving its space utilization rate. Furthermore, both ends of the first slide groove 107 along its length can be open, while one end of the second slide groove 109 along its length can be closed.

[0155] It should be noted that in some other possible embodiments, the first groove 107 and the second groove 109 may both be located on the first side 121, and the first groove 107 and the second groove 109 may be distributed at intervals in the thickness direction of the plate body 119.

[0156] Figure 28 for Figure 26 A top view of another form of pivot mechanism 100 in its unfolded state. Figure 29 For along Figure 28 A cross-sectional view along line OO. In some 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 groove 107, and the first guide member 106 is limited by the groove walls on opposite sides of the first slide groove 107. The end of the second guide member 108 is in contact with the groove wall on one side of the second slide groove 109. However, since the first guide member 106 is located in the first slide groove 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 from detaching from the door panel 105. For the relationship between the first guide member 106 and the first slide groove 107, and the relationship between the second guide member 108 and the second slide groove 109 when the first swing arm 102 is in the folded position relative to the base 101, please refer to the section on...

For columnar structures, their radial cross-sections can be circular or elliptical. The diameters of the radial cross-sections of the first guide 106 and the second guide 108 can be the same or different, and this application does not impose any limitations.

[0158] It should be noted that in another form of the rotating shaft mechanism 100 of this application embodiment, the connection method between the first swing arm 102 and the connecting block 104, and the connection method between the second swing arm 103 and the connecting block 104, can be found in [reference needed].

[0159] See Figure 31 As shown, Figure 31 This is a partial top view of another form of the pivot mechanism 100 in this application embodiment without the door panel 105 and connecting block 104 installed. Figure 31The pivot mechanism 100 is in the unfolded state. In some 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. The direction from one end of the first guide member 106 to the opposite end of the first guide member 106 is the same as the direction from one end of the second guide member 108 to the opposite end of 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 improving 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, which are both located on the second side 122 of the first groove seat 120 of the door panel 105. Please refer to Figure 27 and Figure 31 As shown. Figure 31 As shown, when the first swing arm 102 is in the extended 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: 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 less than the distance between the second guide member 108 and the base 101. Specifically, the distance between the center line S of the first guide member 106 and the base 101 is less than the distance between the center line S of the second guide member 108 and the base 101. In this way, when the first swing arm 102 is in the extended position relative to the base 101, at least the first guide member 106 is still in a movable connection with the first slide groove 107.

[0160] See Figure 31As shown, when the first swing arm 102 is in the extended position relative to the base 101, the projections of the first guide member 106 and the second guide member 108 in the set 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 extended position relative to the base 101, the distance between the boundary line closest to the base 101 in the projection of the first guide member 106 in the set plane and the boundary line farthest from the base 101 in the projection of the second guide member 108 in the set plane is greater than either the first distance or the second distance. The first distance is the width of the projection of the first guide member 106 in the set 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 set plane in the width direction of the rotating shaft mechanism 100. The set plane is perpendicular to the thickness direction of the rotating shaft mechanism 100 and parallel to the width direction of the rotating shaft mechanism 100. In this way, when the first swing arm 102 is in the extended position relative to the base 101, the first guide member 106 and the second guide member 108 are spaced apart relative to each other on the first swing arm 102 in the width direction of the pivot mechanism 100, thereby ensuring that the door panel 105 does not detach from the first swing arm 102. In one embodiment, when both the first guide member 106 and the second guide member 108 are 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 unique plane; it can be any plane that is perpendicular to the thickness direction of the pivot mechanism 100 and parallel to the width direction of the pivot mechanism 100.

[0161] It should be noted that, Figure 26 , Figure 28 , Figure 30 and Figure 31 The rotating shaft mechanism 100 shown is of the same type. In some other possible embodiments, besides... Figure 27 In the case where the first slide groove 107 and the second slide groove 109 are both located on the second side 122, the first slide groove 107 and the second slide groove 109 can also be provided on the first side 121 of the first slot seat 120. At the same time, the first slide groove 107 and the second slide groove 109 are provided on the first side 122 of the first slot seat 120. On the two opposite slot walls of the corresponding recessed groove 116, each slot wall is provided with a first guide 106 and a second guide 108, and the first slide groove 107 and the second slide groove 109 corresponding to and cooperating with the first side 121 and the second side 122 of the first slot seat 120.

In some other embodiments, the first groove 107 and the second groove 109 are located on the same side of the first groove seat 120, for example, as shown in... Figure 33 As shown, both the first slide groove 107 and the second slide groove 109 are located on the second side 122. The forms of the first slide groove 107 and the second slide groove 109, as well as their positional relationship, can be found in [reference needed]. Figure 27 and to Figure 27 The relevant textual descriptions will not be repeated here.

The second slider 124 moves in the fifth slide groove 123. In this way, the cooperation between the fifth slide groove 123 and the second slider 124 further enables precise control of the movement of the door panel 105.

[0164] It should be noted that in some other possible embodiments, when the first slide 107 and the second slide 109 are respectively located on the first side 121, the second side 122 has a curved fifth slide 123, and the connecting block 104 is provided with a second slider 124 that cooperates with the fifth slide 123, and the second slider 124 moves in the fifth slide 123.

Figure 36 For along Figure 35 A cross-sectional view of the QQ line. In some other embodiments, the shape of the second slider 124 is similar to the shape of the fifth slide groove 123, so that the contact form between the second slider 124 and the fifth slide groove 123 is a low pair, thereby realizing the rotational connection between the connecting block 104 and the door panel 105.

[0166] Figure 37 This is a partial structural diagram of another type of pivot mechanism 100 provided in the embodiments of this application, without the door panel 105 installed. Figure 37 The rotating shaft mechanism 100 is in the unfolded state. When the first swing arm 102 is in the unfolded position, the second slider 124 is located in the recessed groove 116 of the first swing arm 102.

[0167] It should be noted that, Figure 32, Figure 35 and Figure 37 The rotating shaft mechanism 100 shown is of the same type. Figure 32 Another type of rotating shaft mechanism 100 and Figure 26 The difference between this type of rotating shaft mechanism 100 and another type is that... Figure 32 In the rotating shaft mechanism 100, the door panel 105 and the connecting block 104 are also connected by a fifth sliding groove 123 and a second sliding block 124. And for... Figure 32 Other structures of the rotating shaft mechanism 100 shown are similar to Figure 26 The related structure of the rotating shaft mechanism 100 shown is the same, therefore Figure 32 For other descriptions of the rotating shaft mechanism 100 shown, excluding the differences mentioned above, please refer to the description of... Figure 26 The description of the rotating shaft mechanism 100 is omitted here.

[0168] In summary, the pivot mechanism 100 and electronic device in at least one embodiment of this application, by providing a first guide 106 and a second guide 108 on the first swing arm 102, and respectively cooperating with the first slide groove 107 and the second slide groove 109 on the door panel 105, control the movement of the door panel 105. This solves the problems in related technologies where the movement of the door panel 105 cannot be accurately controlled at certain angles and the door panel 105 can detach from the first swing arm 102 under narrow door panel 105 designs, without increasing the thickness and width space of the additional pivot mechanism 100. Both the first swing arm 102 and the door panel 105 can be manufactured using molds, with guides provided on the first swing arm 102 and slide grooves designed on the door panel 105 to cooperate with the guides. This design is relatively simple and makes the assembly between the first swing arm 102 and the door panel 105 relatively simple, without increasing additional processing and assembly costs.

[0169] In the description of this application, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples. Regarding the mating relationship between the first swing arm and the door panel, in some possible embodiments, the guide component on the first swing arm and the first and second sliding grooves on the door panel may be arranged in reverse order; that is, the first and second sliding grooves are provided on the first swing arm, while the guide component is provided on the door panel. Thus, when the first swing arm is in the unfolded position relative to the base, it engages with the first guide component on the door panel, and when the first swing arm is in the folded position relative to the base, it engages with the second guide component on the door panel. Furthermore, in yet other possible embodiments, the first guide component may be provided on the first swing arm, the first sliding groove on the door panel, and the second guide component on the door panel, while the second sliding groove is provided on the first swing arm; or, the second guide component may be provided on the first swing arm, the second sliding groove on the door panel, and the first guide component on the door panel, while the first sliding groove is provided on the first swing arm.
