Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a rotating mechanism and a folding terminal. Background Technology

[0002] With the development of flexible screen technology, flexible screens are being used more and more widely in electronic devices, especially foldable terminals (such as foldable phones, foldable tablets, foldable computers, etc.). Currently, in order to achieve synchronous rotation during folding or unfolding, foldable terminals usually use a rotating mechanism to drive the two sides of the body (also known as the mid-frame) to rotate synchronously in opposite directions, thereby switching between folded and unfolded states.

[0003] The current rotating mechanism includes a door panel, a base, a bearing cover, and a swing arm. The door panel, base, and bearing cover are stacked and assembled along the thickness direction of the folding end and connected by screws. The body on both sides of the folding end is connected to the swing arm of the rotating mechanism. The door panel and base together define a slide groove, and the swing arm slides along the groove to rotate the body. However, the clearance of the slide groove in the existing rotating mechanism can change, causing a change in the fit clearance between the swing arm and the slide groove. This can lead to the swing arm being unable to rotate, causing a jamming phenomenon and affecting the user experience. Summary of the Invention

[0004] This application provides a rotating mechanism and a folding terminal. At least two of the door panel, base, and shaft cover in the rotating mechanism are connected by tenon and mortise joints at their ends, reducing the possibility of changes in the clearance of the slide groove and ensuring that the fit clearance between the swing arm and the slide groove remains constant, preventing the swing arm from jamming due to inability to rotate. The following describes this application from multiple aspects, and the embodiments and beneficial effects described below can be referenced interchangeably.

[0005] The first aspect of this application provides a rotating mechanism. Specifically, the rotating mechanism includes: a door panel extending along a first direction; a shaft cover extending along the first direction; and a base extending along the first direction. Along a second direction, the base is disposed between the door panel and the shaft cover. The base and the door panel together define a first sliding groove (also referred to as a left sliding groove) that restricts a first rotating shaft and a second sliding groove (also referred to as a right sliding groove) that restricts a second rotating shaft. Along a third direction, the first and second sliding grooves are spaced apart. The first direction intersects the second direction, and the second direction intersects the third direction. Along the first direction, the base includes a middle portion and an end portion. Along the second direction, the middle portion of the base is connected to the door panel, and at least two of the end portions of the base, the door panel, and the shaft cover are mortise and tenon-jointed to each other.

[0006] For example, the first swing arm is connected to the first slide groove via the first pivot, and the second swing arm is connected to the second slide groove via the second pivot.

[0007] Using the above technical solution, in this embodiment, the middle part of the base is connected to the door panel, and at least two of the ends of the base, the door panel, and the shaft cover are mortised and tenoned together, so that the distance between the upper and lower groove surfaces of the first sliding groove restricting the first rotating shaft and the second sliding groove restricting the second rotating shaft, formed by the base and the door panel, is fixed. This makes the fitting clearance between the first sliding groove and the first swing arm (specifically including the fitting clearance between the first rotating shaft and the upper groove surface of the first sliding groove, also referred to as the upper sliding groove, and the fitting clearance between the first rotating shaft and the lower groove surface of the first sliding groove, also referred to as the lower sliding groove) fixed. The first rotating shaft is fixed with a groove, and the second rotating shaft is fixed with a matching clearance between the second rotating shaft and the upper groove surface of the second groove (also called the upper groove, and the matching clearance between the second swing arm and the lower groove surface of the second groove, also called the lower groove). The first rotating shaft can slide smoothly in the first groove, and the second rotating shaft can slide smoothly in the second groove, thereby avoiding jamming when the rotating shaft slides in the groove (for example, when the first rotating shaft slides in the first groove), due to the excessive matching clearance between the rotating shaft and the upper and lower grooves.

[0008] In addition, in this embodiment, at least two of the base end, door panel and shaft cover are mortise and tenon connected to each other, which can not only play a mechanical locking role between the door panel, shaft cover and base, but also take advantage of the small space occupied by the mortise and tenon structure to make enough space for connection between the middle part of the base and the door panel.

[0009] At the same time, there is enough structural space to mechanically fasten the door panel and the axle cover without introducing other foreign objects (such as glue), which reduces the cost and difficulty of the repair solution.

[0010] For example, the assembly method of the rotating mechanism in this application embodiment includes: first, positioning the end of the base with the door panel; then, fixing the middle part (or the middle part and the tail part) of the base to the door panel, and connecting the end of the base with the door panel through tenon and mortise joints to form a "door panel-base" module, so that the gap between the door panel and the base in the Z-axis direction (i.e., the second direction, which can also be understood as the thickness direction) is fixed; finally, fixing the axle cover to the above-mentioned "door panel-base" module to play a mechanical locking role.

[0011] The door panel and base are connected first, and then the axle cover is installed. Compared with installing three structures (door panel, base and axle cover) together, this provides installation stability. At the same time, the door panel and base can be locked together by mortise and tenon joints. Compared with the form of locking with multiple screws, this simplifies the assembly process, improves production efficiency, and is mass-producible.

[0012] It should be noted that the mortise and tenon joint connection between at least two of the base end, door panel and axle cover mentioned above means that the base end is mortise and tenon jointed with the door panel; or, the base end is mortise and tenon jointed with the axle cover; or, the door panel is mortise and tenon jointed with the axle cover; or, the base end, door panel and axle cover are mortise and tenon jointed in pairs.

[0013] In one possible implementation of the first aspect described above, the base has a first mortise at its end and the door panel has a second mortise, with the first mortise and the second mortise being arranged opposite each other along a third direction; the rotating mechanism also includes a tenon, and the first and second mortise are configured to be connected by a tenon and mortise joint.

[0014] Using the above technical solution, the first tenon groove of this application embodiment is provided at the end of the base (e.g., the first end and the second end of the base at both ends), and the second tenon groove is provided on the door panel. The first tenon groove and the second tenon groove together with the tenon form a tenon and mortise structure, thereby enabling the end of the base to be tenon and mortise connected to the door panel, realizing the mechanical locking and mutual positioning of the end of the base and the door panel, and saving the connection space between the base and the door panel.

[0015] For example, the mortise and tenon connection in this application embodiment refers to a connection method in which concave and convex parts are combined on two components. For example, the mortise (concave structure) and the tenon (convex structure) at the end of the base are connected by combining concave and convex parts.

[0016] In one possible implementation of the first aspect described above, the rotating mechanism further includes a tenon, the end of the base having a first mortise, the tenon being integrally formed with the door panel and mortised and tenoned with the first mortise along a third direction; or, the door panel having a second mortise, the tenon being integrally formed with the end of the base and mortised and tenoned with the second mortise along a third direction.

[0017] By adopting the above technical solution, the embodiments of this application integrally form the ends of the base (e.g., the first end and the second end) with the tenon, thereby achieving mechanical locking and positioning between the ends of the base and the door panel through the tenon provided at the ends of the base and the second mortise of the door panel, saving the connection space between the base and the door panel.

[0018] Furthermore, the end of the base is integrally formed with the tenon, without the need for a separate tenon. When assembling the base and the door panel, the tenon integrally formed with the end of the base can be directly inserted into the second mortise of the door panel to achieve the mortise and tenon connection between the end of the base and the door panel, making the assembly of the rotating mechanism simpler.

[0019] In addition, embodiments of this application can also integrally form the door panel and the tenon to achieve the same mortise and tenon connection between the end of the door panel and the base.

[0020] In one possible implementation of the first aspect described above, the base has a first mortise at its end and the shaft cover has a third mortise, with the first and third mortises arranged opposite each other along a third direction; the rotating mechanism also includes a tenon, and the first and third mortises are configured to be connected by a tenon joint.

[0021] Using the above technical solution, in this application embodiment, the first tenon groove is provided at the end of the base, and the third tenon groove is provided at the shaft cover. The first tenon groove and the third tenon groove together with the tenon form a tenon and mortise structure, thereby enabling the end of the base to be tenon and mortise connected to the shaft cover, realizing the mechanical locking and mutual positioning of the end of the base and the shaft cover, and saving the connection space between the base and the shaft cover.

[0022] In one possible implementation of the first aspect described above, the rotating mechanism further includes a tenon, the end of the base having a first mortise, the tenon being integrally formed with the shaft cover and mortised and tenoned with the first mortise along a third direction; or, the shaft cover having a third mortise, the tenon being integrally formed with the end of the base and mortised and tenoned with the third mortise along a third direction.

[0023] By adopting the above technical solution, the tenon and the shaft cover are integrally formed, eliminating the need for a separate tenon. During the assembly of the base and the shaft cover, the tenon integrally formed with the shaft cover is directly inserted into the first mortise of the base to achieve a mortise and tenon connection between the end of the base and the shaft cover, reducing the assembly steps and difficulty. Similarly, integrally forming the tenon with the end of the base also eliminates the need for a separate tenon, further reducing the assembly steps and difficulty.

[0024] In one possible implementation of the first aspect described above, the door panel has a second tenon, the shaft cover has a third tenon, and the second tenon and the third tenon are arranged opposite to each other along the first direction; the rotating mechanism also includes a tenon, and the second tenon and the third tenon are configured to be connected by a tenon and mortise.

[0025] Using the above technical solution, in this embodiment of the application, the second tenon groove is provided on the door panel, and the third tenon groove is provided on the shaft cover. The second tenon groove and the third tenon groove together with the tenon form a mortise and tenon structure, thereby enabling the door panel and the shaft cover to be mortised and tenoned, realizing the mechanical locking and positioning of the door panel and the shaft cover, and saving the connection space between the door panel and the shaft cover.

[0026] In one possible implementation of the first aspect described above, the rotating mechanism further includes a tenon, the door panel having a second mortise, the tenon being integrally formed with the shaft cover and mortised and tenoned with the second mortise along the first direction; or, the shaft cover having a third mortise, the tenon being integrally formed with the door panel and mortised and tenoned with the third mortise along the first direction.

[0027] By adopting the above technical solution, the tenon and the axle cover are integrally formed, eliminating the need for a separate tenon. During the assembly of the door panel and the axle cover, the tenon, integrally formed with the axle cover, is directly inserted into the second mortise of the door panel to achieve a mortise and tenon connection, reducing assembly steps and difficulty. Similarly, integrally forming the tenon with the door panel also eliminates the need for a separate tenon, further reducing assembly steps and difficulty.

[0028] In one possible implementation of the first aspect described above, the structure of the first mortise at the end of the base includes any one of a straight mortise, a cross-shaped mortise, or a trapezoidal mortise; the structure of the tenon is adapted to the structure of the first mortise.

[0029] In one possible implementation of the first aspect mentioned above, the structure of the second tenon groove of the door panel includes any one of a straight tenon groove, a cross-shaped tenon groove, or a trapezoidal tenon groove; the structure of the tenon is adapted to the structure of the second tenon groove.

[0030] In one possible implementation of the first aspect mentioned above, the structure of the third tenon of the shaft cover includes any one of a straight tenon, a cross-shaped tenon, or a trapezoidal tenon; the structure of the tenon is adapted to the structure of the third tenon.

[0031] In one possible implementation of the first aspect described above, the base includes a first end and a second end; along a first direction, the first end and the second end are located on opposite sides of the middle portion, and the first end and the second end are respectively tenon-mortise connected to the door panel; the first end includes a through hole extending along a second direction, the door panel includes a first fixing part, and the shaft cover includes a second fixing part corresponding to the first fixing part; the rotating mechanism further includes a fixing member, along the second direction, the first fixing part and the second fixing part are connected by the fixing member so that the door panel and the shaft cover are fixedly connected, the fixing member passes through the through hole, and the hole wall of the through hole is spaced apart from the fixing member.

[0032] In this embodiment, the base is mechanically locked and positioned to the door panel by mortise and tenon joints with the first and second ends of the base, saving connection space between the base and the door panel. Thus, on the side near the first end of the base, there is enough space for the door panel and the shaft cover to be connected, so that the first fixing part (e.g., the first threaded hole) on the door panel and the second fixing part (e.g., the second threaded hole) on the shaft cover are connected and fixed by fasteners (e.g., screws).

[0033] In addition, in this embodiment, a through hole is provided on the base, and the side wall of the through hole is spaced apart from the fastener passing through the through hole, so that when the fastener passes through the through hole to connect the first fastener and the second fastener, the fastener can connect the door panel and the shaft cover without connecting to the base, so as to avoid interference between the fastener and the base and realize the mechanical locking of the door panel, the base and the shaft cover.

[0034] In one possible implementation of the first aspect described above, the base near the first end further includes a third fixing part, and the door panel further includes a fourth fixing part corresponding to the third fixing part; along the second direction, the third fixing part and the fourth fixing part are connected by a fastener so that the base near the first end is fixedly connected to the door panel.

[0035] Using the above technical solution, in this embodiment of the application, a third fixing part is provided on one side near the first end of the base, and a fourth fixing part corresponding to the third fixing part is provided on the door panel. The third fixing part and the fourth fixing part are then connected by a fastener to achieve a fixed connection between the side near the first end of the base and the door panel, thereby further strengthening the connection between the base and the door panel.

[0036] In one possible implementation of the first aspect described above, the base near the second end further includes a third fixing part, and the door panel further includes a fourth fixing part corresponding to the third fixing part; along the second direction, the third fixing part and the fourth fixing part are connected by a fastener so that the base near the second end is fixedly connected to the door panel.

[0037] Using the above technical solution, in this embodiment of the application, a third fixing part is provided on one side near the second end of the base, and a fourth fixing part corresponding to the third fixing part is provided on the door panel. The third fixing part and the fourth fixing part are then connected by a fastener to achieve a fixed connection between the side near the second end of the base and the door panel, thereby further strengthening the connection between the base and the door panel.

[0038] In one possible implementation of the first aspect described above, the middle portion of the base includes a fifth fixing portion, and the door panel includes a sixth fixing portion corresponding to the fifth fixing portion; the rotating mechanism further includes a fixing member, and the fifth fixing portion and the sixth fixing portion are connected by the fixing member along the second direction so that the middle portion of the base is fixedly connected to the door panel.

[0039] Using the above technical solution, in this embodiment of the application, a fifth fixing part is provided in the middle part of the base, and a sixth fixing part corresponding to the fifth fixing part is provided on the door panel. The fifth fixing part and the sixth fixing part are then connected by a fastener to achieve a fixed connection between the middle part of the base and the door panel, thereby achieving a fixed connection between the middle part near the base and the door panel, and further strengthening the connection between the base and the door panel.

[0040] In one possible implementation of the first aspect described above, the bushing further includes a blocking portion disposed opposite to the tenon along a first direction to restrict the tenon from sliding out of the first mortise or the second mortise, or to restrict the tenon from sliding out of the first mortise and the second mortise.

[0041] Using the above technical solution, the embodiment of this application provides a blocking part in the shaft cover, and the end of the base is connected to the door panel through a first tenon, a second tenon and a tenon. The blocking part is arranged opposite to the tenon to prevent the tenon from coming out and affecting the connection between the door panel and the base, thus ensuring the reliability and stability of the assembly of the door panel and the base.

[0042] In one possible implementation of the first aspect described above, the number of bases includes multiple bases, which are spaced apart on the door panel along the first direction.

[0043] A second aspect of this application provides a rotating mechanism, comprising: a first part; a second part, the second part being tenon-and ...

[0044] This rotating structure can be applied to devices that require control over the consistency of rotation along the axis and the gap between the two sides of the axis when closed, such as laptop hinges and headphone (e.g., wireless headphone) charging cases.

[0045] Using the above technical solution, the embodiments of this application use a mortise and tenon joint between the first part and the second part to achieve mechanical locking and mutual positioning of the first part and the second part.

[0046] Furthermore, this embodiment uses a mortise and tenon joint to connect the first and second parts, thereby fixing the fit clearance between the groove formed by the first and second parts and the rotating part, preventing jamming. It also avoids introducing foreign objects (such as adhesive), reducing the cost and difficulty of rework. The specific structure of the first and second parts in this rotating mechanism is not limited; any structure capable of forming a groove falls within the protection scope of this embodiment (e.g., two structures forming a groove in a laptop or headphone charging case). Additionally, the rotating part in this rotating mechanism can be a structure capable of sliding / rotating relative to the groove, such as a laptop screen or the lid of a headphone charging case.

[0047] A third aspect of this application provides a foldable terminal (e.g., a foldable phone), comprising: a first body; a second body; a first swing arm connected to the first body, the first swing arm including a first pivot; a second swing arm connected to the second body, the second swing arm including a second pivot; a rotation mechanism as described in any of the first aspects, the first swing arm being connected to a first slide groove of the rotation mechanism via the first pivot, the second swing arm being connected to a second slide groove of the rotation mechanism via the second pivot; and a flexible screen covering the first body, the second body, and the rotation mechanism.

[0048] By adopting the above technical solution, the fitting clearance between the slide groove and the rotating shaft of the swing arm in the rotating mechanism of this application embodiment is fixed, and the swing arm slides more smoothly in the slide groove. As a result, the first body of the folding terminal rotates more smoothly through the first swing arm, and the second body of the folding terminal rotates more smoothly through the second swing arm. This avoids the swing arm jamming phenomenon during the use of the folding terminal, improves the user experience, and also extends the service life of the folding terminal.

[0049] In addition, the rotating mechanism of the folding terminal in this embodiment does not introduce other foreign objects (such as glue), which also reduces the cost and difficulty of the folding terminal repair solution. Attached Figure Description

Detailed Implementation

[0094] This application provides a rotating mechanism and a folding terminal, the rotating mechanism of which can be applied to the folding terminal. Specifically, the folding terminal includes, but is not limited to, foldable mobile phones, tablet computers, e-book readers, laptop computers, personal digital assistants (PDAs), personal computers, notebook computers, in-vehicle devices, wearable devices (such as watches), boxes, and other electronic devices that need to be opened and closed.

[0095] For ease of explanation, the following description uses a foldable mobile phone as an example of a foldable terminal. The foldable mobile phone of this application will be introduced below with specific embodiments.

[0096] Figure 1a A perspective view of the unfolded state of a foldable phone according to an embodiment of this application is shown. Figure 1b A perspective view of the folded state of a foldable phone according to an embodiment of this application is shown.

[0097] For ease of subsequent description, before describing the specific structure of the foldable phone 1, this application will first combine... Figure 1a and Figure 1b Define the Y direction (as the first direction), Z direction (as the second direction), and X direction (as the third direction).

[0098] like Figure 1a and Figure 1b As shown, the Y direction is the width direction of the foldable phone 1. The width direction can be the width direction of the flexible screen 400 (mentioned below), or it can be understood as the direction perpendicular to the direction in which the user holds the flexible screen 400 in the plane, or it can be the length direction of the rotating mechanism described later. The Z direction is the thickness direction of the foldable phone 1, or it can be the thickness direction of the rotating mechanism described later. The X direction is the length direction of the foldable phone. The length direction can be the length direction of the flexible screen 400 (mentioned below), or it can be understood as the direction in which the user holds the phone, or it can be the width direction of the rotating mechanism described later.

[0099] The first direction, the second direction, and the third direction intersect each other. The following example illustrates this by showing that the X direction, Z direction, and X direction are mutually perpendicular.

[0100] It is understood that the parallelism in the embodiments of this application is not absolute parallelism. Approximate parallelism due to processing and assembly errors (e.g., an angle of 0.1° between two structural features) is also within the scope of mutual parallelism in the embodiments of this application. Similarly, the perpendicularity in the embodiments of this application is not absolute perpendicularity. Approximate perpendicularity due to processing and assembly errors (e.g., an angle of 89.9° between two structural features) is also within the scope of mutual perpendicularity in the embodiments of this application. The limitations of mutual parallelism and mutual perpendicularity will not be repeated below.

[0101] Combination Figure 1a and Figure 1b It is known that the foldable phone 1 includes a rotating mechanism 100, a first body 200 (also referred to as a first mid-frame), a second body 300 (also referred to as a second mid-frame), and a flexible screen 400. Among them, as shown... Figure 1a As shown, along the X direction, i.e., along the length of the folding phone, the first body 200 and the second body 300 are respectively disposed on opposite sides of the rotating mechanism 100. The first body 200 and the second body 300 are respectively connected to the rotating mechanism 100 and can rotate relative to each other. Exemplarily, the first body 200 and the second body 300 constitute the supporting frame of the folding phone 1. Electronic components, such as batteries and control circuit boards (not shown in the figure), are disposed inside the first body 200 and the second body 300.

[0102] The flexible screen 400 is fixed to the first body 200, the second body 300, and the rotating mechanism 100. The flexible screen 400 includes a first flexible screen 401 and a second flexible screen 402 connected to each other. Specifically, the first flexible screen 401 is disposed between the rotating mechanism 100 and the first body 200, and the second flexible screen 402 is disposed between the second body 300. The flexible screen 400 can be an organic light-emitting diode (OLED) screen, a micro organic light-emitting diode (micro organic light-emitting diode) screen, a quantum dot light-emitting diode (QLED) screen, a liquid crystal display (LCD), etc.

[0103] For example, the rotating mechanism 100 and the first body 200 are covered by the first flexible screen 401, and the second body 300 is covered by the second flexible screen 402. The first body 200 rotates relative to the rotating mechanism 100, which can drive the first flexible screen 401 to move; the second body 300 rotates relative to the rotating mechanism 100, which can drive the second flexible screen 402 to move, so that the flexible screen 400 is in a bent state or an unfolded state, thereby allowing the foldable phone 1 to switch between a folded state and an unfolded state.

[0104] Specifically, in some embodiments, the first body 200 and the second body 300 can rotate relative to each other left and right via the rotating mechanism 100 to unfold or fold the first flexible screen 401 and the second flexible screen 402. Alternatively, in some other embodiments, the first body 200 and the second body 300 can also rotate relative to each other up and down via the rotating mechanism 100 to fold or unfold the flexible screen. This application does not limit the relative rotation direction of the first body 200 and the second body 300.

[0105] Figures 2a to 2d A partial schematic diagram of the rotating mechanism in some embodiments is shown. Figure 2a This is a cross-sectional view along the thickness direction of a rotating mechanism provided in some embodiments; Figure 2b This is a cross-sectional view along the length of a rotating mechanism provided in some embodiments, wherein the first and second swing arms are not shown; Figure 2c This is a perspective view of a rotating mechanism provided in some embodiments, wherein the first and second swing arms are not shown; Figure 2d This is a bottom view of a rotating mechanism provided in some embodiments, where the first and second swing arms are not shown.

[0106] In some implementations, reference Figure 2a and Figure 2b The rotating mechanism includes a first swing arm 110, a second swing arm 120, a door panel 130, a base 140, and a shaft cover 150, which are combined Figure 1a The first swing arm 110 of the rotating mechanism 100 is connected to the first body 200, and the second swing arm 120 of the rotating mechanism is connected to the second body 300. The door panel 130, base 140, and shaft cover 150 are along the thickness direction of the rotating mechanism (…). Figure 2a The interval setting is shown in the second direction Z.

[0107] Among them, combined Figure 2c The door panel 130 and the base 140 are spaced apart along the thickness direction (i.e., the second direction Z) of the rotating mechanism to jointly define the first slide groove 160 that restricts the first rotating shaft 111 and the second slide groove 170 that restricts the second rotating shaft 121. Figure 2a As can be seen, one end of the first swing arm 110 is slidably connected to the first slide groove 160 via the first rotating shaft 111. Figure 2a As can be seen, the first swing arm 110 rotates around the first axis (not shown in the figure), the first axis extending along the width direction Y of the folding phone; one end of the second swing arm 120 is slidably connected to the second slide groove 170 through the second rotating shaft 121, so that the second swing arm 120 rotates around the second axis (not shown in the figure), the second axis extending along the width direction Y of the folding phone, that is, the second axis is parallel to the first axis, thereby realizing the opening and closing of the folding phone 1, and the rotation directions of the first swing arm 110 and the second swing arm 120 are opposite.

[0108] Specifically, the shape of the first slide groove 160 is adapted to the shape of the first rotating shaft 111 at one end of the first swing arm 110, and the first slide groove 160 and the first rotating shaft 111 have a certain fitting gap to ensure that the first rotating shaft 111 can slide smoothly in the first slide groove 160, that is, the first swing arm 110 can drive the first body 200 to open and close smoothly.

[0109] refer to Figure 2b and Figure 2d Along the length direction of the rotating mechanism (i.e., the first direction Y), the base 140 includes two end portions and a middle portion 142. For ease of description, the end portion on the right is designated as the first end portion 141, and the end portion on the left is designated as the second end portion 143. Near the first end portion 141 of the base 140, the base 140 is locked to the door panel 130 by two screws 190. Figure 2d (As can be seen); on one side near the second end 143 of the base 140, the base 140 is locked to the door panel 130 by a screw 190. Figure 2d (As can be seen); in the middle part 142 of the base 140, the door panel 130 and the shaft cover 150 are locked by screws 190 (as shown). Figure 2d As shown in the figure, this is used to fix the door panel 130, the base 140 and the shaft cover 150 together.

[0110] However, since the door panel 130 is usually made of carbon fiber or zirconium-based amorphous material, the material strength is low and it is easy to deform. This results in the door panel 130 and the axle cover 150 being not firmly fixed in the thickness direction (i.e., the second direction Z) of the rotating mechanism. The door panel 130 is prone to shaking. As a result, the distance between the door panel 130 and the base 140 in the thickness direction (i.e., the second direction Z) of the rotating mechanism increases, that is, the gap between the first slide groove 160 and the second slide groove 170 between the door panel 130 and the base 140 will increase.

[0111] An example is given regarding the fit clearance between the first rotating shaft 111 and the first sliding groove 160. When the first rotating shaft 111 and the upper groove surface 163 of the first sliding groove 160 (… Figure 2a The fit clearance (which can be called the upper groove) between the first rotating shaft 111 and the lower groove surface 164 of the first groove 160 increases, as can be seen. Figure 2aThe fit clearance (which can be called the sliding groove) will become smaller; or, when the first rotating shaft 111 and the upper groove surface 163 of the first sliding groove 160 (see) Figure 2a The fit clearance (which can be called the upper groove) between the first rotating shaft 111 and the lower groove surface 164 of the first groove 160 becomes smaller. Figure 2b As can be seen, the clearance (which can be called the sliding groove) will increase, causing the first rotating shaft 111 to be unable to rotate, resulting in a jamming problem. Similarly, the second rotating shaft 121 will also have the same problem.

[0112] Alternatively, the distance between the door panel 130 and the base 140 in the thickness direction (i.e., the second direction Z) of the rotating mechanism may decrease, meaning the gap between the first sliding groove 160 and the second sliding groove 170 between the door panel 130 and the base 140 will decrease. This will result in a smaller fit clearance between the first rotating shaft 111 and the upper groove surface 163 of the first sliding groove 160, and a larger fit clearance between the first rotating shaft 111 and the lower groove surface 164 of the first sliding groove 160. Alternatively, the fit clearance between the first rotating shaft 111 and the upper groove surface 163 of the first sliding groove 160 may increase, while the fit clearance between the first rotating shaft 111 and the lower groove surface 164 of the first sliding groove 160 may decrease, preventing the first rotating shaft 111 from rotating and causing a jamming problem. Similarly, the second rotating shaft 121 will also experience the same problem.

[0113] Alternatively, if the gap in the first slide groove 160 becomes larger and the gap in the second slide groove 170 becomes smaller, the aforementioned problems will also occur.

[0114] Alternatively, the gap of the first slide groove 160 may increase or decrease, causing the first rotating shaft 111 to experience the aforementioned jamming problem; or the gap of the second slide groove 170 may increase or decrease, causing the second rotating shaft 121 to experience the aforementioned jamming problem.

[0115] However, even if the material of the door panel 130 is changed to a stronger material, such as stainless steel, since only the door panel 130 and the axle cover 150 are fixed in the middle part 142 of the base 140, the base 140 is not fixed. The base 140 is prone to shaking in the Z direction, which will cause the problems mentioned above.

[0116] Specifically, combined Figure 2a The first slide groove 160 includes a first groove 161 and a second groove 162, which are connected to form an arc-shaped first slide groove 160. Along the width direction of the rotating mechanism (i.e., the third direction X), the second groove 162 is located to the left of the first groove 161. The first rotating shaft 111 of the first swing arm 110 includes a first part 1111 located in the first groove 161 and a second part 1112 located in the second groove 162.

[0117] When the distance between the door panel 130 and the base 140 along the thickness direction of the rotating mechanism (i.e., the second direction Z) increases, the gap between the first groove 161 and the second groove 162 along the thickness direction of the rotating mechanism (i.e., the second direction Z) also increases.

[0118] For example, the fit clearance between the first portion 1111 and the first groove 161 increases, the fit clearance between the first portion 1111 and the upper groove surface 163 of the first groove 161 (also referred to as the upper sliding groove) increases, and the fit clearance between the first portion 1111 and the lower groove surface 164 of the first groove 161 (also referred to as the lower sliding groove) decreases; or, the fit clearance between the first portion 1111 and the upper groove surface 163 of the first groove 161 (also referred to as the upper sliding groove) decreases, and the fit clearance between the first portion 1111 and the lower groove surface 164 of the first groove 161 (also referred to as the lower sliding groove) increases; the fit clearance between the second portion 1112 and the second groove 162 increases, and the fit clearance between the second portion 1112 and the upper groove surface 164 of the second groove 162... When the clearance between part 3 (also known as the upper sliding groove) increases, the clearance between the second part 1112 and the lower groove surface 164 of the second groove 162 (also known as the lower sliding groove) decreases; or, when the clearance between the second part 1112 and the upper groove surface 163 of the second groove 162 (also known as the upper sliding groove) decreases, the clearance between the second part 1112 and the lower groove surface 164 of the second groove 162 (also known as the lower sliding groove) increases; at this time, when the first rotating shaft 111 rotates, the arc connection section between the second part 1112 and the first part 1111 will be stuck in the first groove 161, causing the first rotating shaft 111 of the first swing arm 110 to be unable to rotate, resulting in the above-mentioned jamming phenomenon, which affects the normal use of the folding phone.

[0119] If the distance between the door panel 130 and the base 140 along the thickness direction of the rotating mechanism (i.e., the second direction Z) becomes smaller, the gap between the first groove 161 and the second groove 162 along the thickness direction of the rotating mechanism (i.e., the second direction Z) will also become smaller, and the jamming problem described above will also occur.

[0120] Similarly, the second pivot 121 of the second swing arm 120 will also experience the above-mentioned jamming phenomenon, which will not be described in detail here.

[0121] To solve the aforementioned stuck problem, in some other implementations, reference is made to... Figures 3a to 3c On one side near the first end 141 of the base 140, the door panel 130 and the base 140 are locked together by two screws 190. Figure 3b (As can be seen); on the side near the second end 143 of the base 140, the door panel 130 and the base 140 are locked together by a screw 190. Figure 3b (See); and in the middle part 142 of the base 140, the door panel 130 and the base 140 are locked together by screws 190 ( Figure 3b visible).

[0122] In other words, the base 140 is completely locked to the door panel 130 by screws 190. That is, the beginning, middle and end of the base 140 and the door panel 130 are locked with screws 190 to fix the door panel 130 and the base 140, and to ensure that the distance between the door panel 130 and the base 140 along the thickness direction (i.e. the second direction Z) of the rotating mechanism is fixed.

[0123] Combination Figure 2a That is, the gap between the first slide groove 160 and the second slide groove 170 between the door panel 130 and the base 140 is fixed. In other words, the fit gap between the first pivot 111 of the first swing arm 110 and the first slide groove 160 is fixed, and the fit gap between the second pivot 121 of the second swing arm 120 and the second slide groove 170 is fixed, thus avoiding the above-mentioned jamming problem.

[0124] Regarding the fixing of the axle cover 150, since both the base 140 and the door panel 130 are locked with screws, there is no other structural space on the plane of the rotating mechanism to further lock the door panel 130 and the axle cover 150 with screws. Therefore, in this embodiment, an adhesive dispensing method is used to mate the base 140 and the axle cover 150.

[0125] Specifically, adhesive is applied to the side of the shaft cover 150 facing the base 140 (not shown), or adhesive is applied to the side of the base 140 facing the shaft cover 150 (not shown), to fix the base 140 and the shaft cover 150.

[0126] However, if the above solution is adopted, the shaft cover 150 will become a decoration and lose its function as a keel, and the rigidity of the rotating mechanism will be reduced. At the same time, the glue will completely stick the base 140 and the shaft cover 150 together, which will increase the difficulty and cost of rework. The glue will also have the risk of coming unglued. Thus, the safety and stability of the rotating mechanism will be affected.

[0127] In addition, foreign matter, namely adhesive, is introduced. During the adhesive dispensing process, the adhesive may penetrate into the first flexible screen 401 and the second flexible screen 402, causing black spots and affecting the user's experience.

[0128] Therefore, this application provides another rotating mechanism to improve the problems arising in the above two embodiments by changing the connection method of the rotating mechanism. Specifically, the connection method of at least two of the door panel, shaft cover, and base of the rotating mechanism can be changed to a mortise and tenon joint, so that the fit clearance between the first swing arm and the upper and lower groove surfaces of the first slide is fixed, and the clearance between the second swing arm and the upper and lower groove surfaces of the second slide is fixed, thereby enabling the first and second swing arms to rotate smoothly; at the same time, it also saves structural space and can fix the door panel, base, and shaft cover without introducing new foreign objects (such as the aforementioned glue).

[0129] The specific connection forms of the rotating mechanism will be described in detail below with reference to the accompanying drawings. Embodiment 1 describes a mortise and tenon connection between the first and second ends of the base and the door panel. Specifically, both the door panel and the base have mortise grooves at the same positions on their front and rear sides, and tenons are used to fix the front and rear Z-axis positions of the door panel and the base. Embodiment 2 describes a mortise and tenon connection between the door panel and the axle cover. Specifically, both the door panel and the axle cover have mortise grooves at the same positions on their front and rear sides, and tenons are used to fix the front and rear Z-axis positions of the door panel and the axle cover. Embodiment 3 describes a mortise and tenon connection between the first and second ends of the base and the axle cover. Specifically, both the axle cover and the base have mortise grooves at the same positions on their front and rear sides, and tenons are used to fix the front and rear Z-axis positions of the axle cover and the base.

[0130] Example 1

[0131] The following is combined with Figures 4a to 9c A detailed description of a rotating mechanism provided in Embodiment 1 is given below.

[0134] refer to Figure 4a and Figure 4b The rotating mechanism 100 includes a first swing arm 110, a second swing arm 120, a door panel 130, a base 140, and a shaft cover 150. The door panel 130, the base 140, and the shaft cover 150 are stacked along the thickness direction (i.e., the second direction Z) of the rotating mechanism 100 to form a "sandwich"-like stacking mechanism, which can effectively ensure the overall flatness of the first swing arm 110 and the second swing arm 120 and simplify the manufacturing process.

[0135] Specifically, the door panel 130 extends along the length direction (i.e., the first direction Y) of the rotating mechanism 100, and the shaft cover 150 extends along the length direction (i.e., the first direction Y) of the rotating mechanism 100; the base 140 includes a plurality of bases, which are spaced apart along the length direction of the rotating mechanism 100 and along the thickness direction (i.e., the second direction Z) of the rotating mechanism 100, each base 140 is disposed between the door panel 130 and the shaft cover 150 to form the aforementioned "sandwich"-like stacking mechanism.

[0136] The specific number of bases 140 can be determined based on the first unit 200 and the second unit 300. Figure 1a The length of the base 140 can be selected, such as four, five, or six. Along the length direction of the rotating mechanism 100 (i.e., the first direction Y), each base 140 includes a first end 141, a middle portion 142, and a second end 143. Figure 4b (As can be seen). That is, the first end 141 and the second end 143 are located on opposite sides of the middle portion 142.

[0137] Similarly, the number of the first slide 160 and the second slide 170 may also include multiple, which can be selected according to the needs of the foldable phone. This application embodiment takes one first slide 160 and one second slide 170 as an example for further explanation.

[0138] This application uses a base 140 in the rotating mechanism 100 as an example for illustration.

[0139] refer to Figure 4b The base 140 is located between the door panel 130 and the shaft cover 150, and is spaced apart from the door panel 130 along the thickness direction of the rotating mechanism (i.e., the second direction Z), so that it together with the door panel 130 defines the first slide groove 160 for limiting the first rotating shaft 111 of the first swing arm 110 and the second slide groove 170 for limiting the second rotating shaft 121 of the second swing arm 120. Figure 2a As can be seen, along the width direction (i.e., the third direction X) of the rotating mechanism, the first slide groove 160 and the second slide groove 170 are spaced apart and located on opposite sides of the width direction of the rotating mechanism.

[0140] In this embodiment of the application, one end of the first swing arm 110 is slidably connected to the first slide groove 160 via the first rotating shaft 111. Figure 2a As can be seen, the other end of the first swing arm 110 is connected to the aforementioned first body 200. Figure 1b (As can be seen); one end of the second swing arm 120 is slidably connected to the second slide groove 170 via the second rotating shaft 121. Figure 2a As can be seen, the other end of the second swing arm 120 is connected to the aforementioned second body 300. Figure 1b visible).

[0141] Therefore, when the foldable phone needs to be folded, the first swing arm 110 moves along the first axis (not shown in the figure) along... Figure 4b Rotating in direction a as shown, and in the first slide groove 160 ( Figure 2a (See image) Slides within, the second swing arm 120 rotates around the second axis (not shown in the figure) along Figure 4b Rotate in direction b as shown, and in the second slide 170 ( Figure 2a (See) Slide inside until the first unit 200 contacts the second unit 300. Figure 1b visible).

[0142] When it needs to be opened, the first swing arm 110 moves around the first axis (not shown) along... Figure 4b When rotated in direction b as shown, the first rotating shaft 111 is in the first slide groove 160 ( Figure 2a (See image) Slides within, the second swing arm 120 rotates around the second axis (not shown in the figure) along Figure 4b When rotated in direction a, the second rotating shaft 121 is in the second slide groove 170 ( Figure 2a (See) Slide inside until the first unit 200 separates from the second unit 300. Figure 1a visible).

[0143] refer to Figure 5a and Figure 5b The first end 141 of the base 140 is tenon-jointed to the door panel 130. Along the thickness direction of the rotating mechanism (i.e., the second direction Z), it is joined... Figure 6aThe middle portion 142 of the base 140 is connected to the door panel 130 by screws 190, and the second end 143 of the base 140 is tenon-jointed to the door panel 130 (not shown in the figure) to fix the distance between the base 140 and the door panel 130 along the thickness direction (i.e., the second direction Z) of the rotating mechanism. Figure 2a The gap between the first slide groove 160 and the second slide groove 170 between the door panel 130 and the base 140 is fixed to avoid the aforementioned jamming problem.

[0144] In some possible implementations, reference is made to Figure 6a Alternatively, only the first end 141 of the base 140 can be tenon-and-mortise connected to the door panel 130. Figure 5a As can be seen, the middle part 142 of the base 140 is connected to the door panel 130 by screws 190. On the side near the second end 143, the base 140 and the door panel 130 are connected by screws 190, which can also fix the distance between the base 140 and the door panel 130 along the thickness direction of the rotating mechanism (i.e., the second direction Z).

[0145] Alternatively, in some possible implementations, only the second end 143 of the base 140 may be tenon-and-mortise connected to the door panel 130 (not shown in the figure), see reference. Figure 6a and Figure 6b The middle part 142 of the base 140 is connected to the door panel 130 by screws 190. On the side close to the first end 141, the base 140 and the door panel 130 are connected by screws 190, which can also fix the distance between the base 140 and the door panel 130 along the thickness direction of the rotating mechanism (i.e., the second direction Z).

[0146] It should be noted that the accompanying drawings of Embodiment 1 of this application only show the mortise and tenon connection between the first end 141 of the base 140 and the door panel 130, but it can be understood that the second end 143 of the base 140 and the door panel 130 have the same mortise and tenon structure.

[0147] refer to Figure 5a and Figure 5b Specifically, the first end 141 of the base 140 has two first tenons 144. For ease of description, along the width direction of the rotating mechanism, the first tenon located on the left is named the first sub-tenon 1440, and the first tenon located on the right is named the second sub-tenon 1441. The first sub-tenon 1440 and the second sub-tenon 1441 are arranged opposite to each other along the width direction of the rotating mechanism.

[0148] refer to Figure 5a and Figure 5bAlong the length of the rotating mechanism, a connector 138 is provided at a position corresponding to the first end 141 of the base 140 on the door panel 130. Along the width of the door panel 130, the two ends of the connector 138 are provided with second mortises 131 that are opposite to each first mortise 144. For ease of description, the mortises corresponding to the first mortises 1440 are called third mortises 1310, and the mortises corresponding to the second mortises 1441 are called fourth mortises 1311. The third mortises 1310 and the fourth mortises 1311 are located on opposite sides of the width of the door panel 130.

[0149] When assembling the base 140 and the door panel 130, the first sub-mortise 1440 and the third sub-mortise 1310 are opposite each other along the width direction of the rotating mechanism to form a concave structure, and are connected by the first tenon 181 (convex structure). That is, the left end of the first tenon 181 is inserted into the first sub-mortise 1440 to achieve the mortise and tenon connection, and the right end of the first tenon 181 is inserted into the third sub-mortise 1310 to achieve the mortise and tenon connection.

[0150] Similarly, the second mortise 1441 and the fourth mortise 1311 are opposite each other along the width direction of the rotating mechanism to form a concave structure, and are connected by the second tenon 182 (convex structure). That is, the right end of the second tenon 182 is inserted into the second mortise 1441 to achieve the mortise and tenon connection, and the left end of the second tenon 182 is inserted into the fourth mortise 1311 to achieve the mortise and tenon connection, so that the first end 141 of the base 140 is mortised and tenon connected to the two sides of the door panel 130 in the width direction.

[0151] The shape of the first tenon 181 is compatible with the shapes of the first mortise 1440 and the third mortise 1310, and both are straight. The shape of the second tenon 182 is compatible with the shapes of the second mortise 1441 and the fourth mortise 1311, and both are straight.

[0152] It is understandable that the first tenon 181 between the first tenon groove 1440 and the third tenon groove 1310 can also be as follows: Figure 7a The cross shape shown, or as Figure 7b The trapezoidal shape shown. The second tenon 182 between the second tenon 1441 and the fourth tenon 1311 can also be as follows. Figure 7a The cross shape shown, or as Figure 7b The trapezoid shown. Similarly, the shape of the first tenon 181 and the shape of the second tenon 182 can be the same or different.

[0153] In some possible implementations, reference is made to Figure 8a The first tenon 181 is integrally formed with the connector 138 on the door panel, and the second tenon 182 is also integrally formed with the door panel (not shown in the figure). The shape of the first tenon 181 is adapted to the first mortise 1440. Figure 8aThe first tenon 181 is shown to be in the shape of a straight line, and correspondingly, the first mortise 1440 is rectangular in shape; similarly, the shape of the second tenon 182 is adapted to the shape of the second mortise 1441 (not shown in the figure).

[0154] In other words, along the width direction of the rotating mechanism, one side of the connector 138 on the door panel protrudes outward (specifically, protrudes along the X direction towards the first tenon 1440) to form a first tenon 181. The shape of this protruding part matches the first tenon 1440, both being straight. The other side of the connector 138 protrudes outward to form a second tenon 182, the shape of which matches the second tenon 1441 (not shown in the figure). Thus, referring to... Figure 8b When assembling the door panel 130 and the base 140, it is only necessary to insert the first tenon 181 into the first mortise 1440 along the width direction of the rotating mechanism, and insert the second tenon 182 into the second mortise 1441 along the width direction of the rotating mechanism to make a tenon-mortise connection.

[0155] Or, refer to Figure 8c The first tenon 181 is integrally formed with the base 140, and the second tenon 182 is integrally formed with the base 140 (not shown in the figure). The shape of the first tenon 181 is adapted to the shape of the third mortise 1310, and the shape of the second tenon 182 is adapted to the shape of the fourth mortise 1311 (not shown in the figure).

[0156] In other words, along the width direction of the rotating mechanism, one side of the base 140 protrudes outward (specifically, protrudes along the X direction towards the third mortise 1310) to form the first tenon 181. The shape of this protruding part matches the third mortise 1310, both being straight. The other side of the base 140 protrudes outward to form the second tenon 182, the shape of which matches the fourth mortise 1311. Thus, when assembling the door panel 130 and the base 140, it is only necessary to insert the first tenon 181 into the third mortise 1310 along the width direction of the rotating mechanism, and insert the second tenon 182 into the fourth mortise 1311 along the width direction of the rotating mechanism to achieve the mortise and tenon connection.

[0157] It is understandable that the first tenon 181 could be integrally formed with the base 140, and the second tenon 182 could be integrally formed with the door panel 130; the first tenon 181 could be integrally formed with the door panel 130, and the second tenon 182 could be integrally formed with the base 140; or only the first tenon 181 could be integrally formed with the base 140, and the second tenon 182 could be set separately; or only the first tenon 181 could be integrally formed with the door panel 130, and the second tenon 182 could be set separately; or only the second tenon 182 could be integrally formed with the door panel 130, and the first tenon 181 could be set separately; or only the second tenon 182 could be integrally formed with the base 140, and the first tenon 181 could be set separately.

[0158] It should be noted that the specific positions of the first mortise 144 and the second mortise 131 are not limited in the embodiments of this application, and can be as follows: Figure 5b The arrangement shown can be either relative to each other along the width direction or relative to each other along the thickness direction.

[0159] The second end 143 of the base 140 and the door panel 130 have the same mortise and tenon structure as described above, which will not be repeated here.

[0160] refer to Figure 9a and Figure 9b The middle portion 142 of the base 140 includes a fifth threaded hole 148 (which may be referred to as the fifth fixing portion 147), and the door panel 130 includes a sixth threaded hole 135 (which may be referred to as the sixth fixing portion 134) corresponding to the fifth threaded hole 148. The fifth threaded hole 148 and the sixth threaded hole 135 are connected by screws 190. Figure 6a (As can be seen). Specifically, when the door panel 130 is assembled with the base 140, the fifth threaded hole 148 and the sixth threaded hole 135 are arranged opposite each other along the thickness direction of the rotating mechanism (i.e., the second direction Z), and the screw 190 passes through the fifth threaded hole 148 and the sixth threaded hole 135, so that the middle part 142 of the base 140 is fixedly connected to the door panel 130.

[0161] It should be noted that the fifth fixing part 147 and the sixth fixing part 134 can also be riveted or snap-fitted together.

[0162] At the same time, refer to Figure 9a and Figure 9b Because the first mortise 144 of the first end 141 of the base 140 is mortised and tenoned with the second mortise 131 of the door panel 130 through the first tenon 181 and the second tenon 182. Figure 5a and Figure 5b As can be seen, this frees up sufficient structural space on the side of the base 140 near the first end 141 for mounting screws 190. Figure 6b As can be seen, the door panel 130 is connected to the shaft cover 150 by screws 190.

[0163] Specifically, refer to Figure 9b The base 140 has a through hole 149 on the side near the first end 141, and the through hole 149 extends along the thickness direction (i.e., the second direction Z) of the rotating mechanism. (Reference) Figure 9a and Figure 9c The door panel 130 includes a first threaded hole 137 (which may be referred to as a first fixing part 136), and the shaft cover 150 includes a second threaded hole 153 (which may be referred to as a second fixing part 152) corresponding to the first threaded hole 137. Figure 6b The first threaded hole 137 and the second threaded hole 153 are connected by a screw 190.

[0164] When the door panel 130 is assembled with the shaft cover 150, the first threaded hole 137 and the second threaded hole 153 are positioned opposite each other along the thickness direction of the rotating mechanism (i.e., the second direction Z). The screw 190 passes through the first threaded hole 137, the through hole 149, and the second threaded hole 153 in sequence. Figure 6b As can be seen, the shaft cover 150 is fixedly connected to the door panel 130 on the side near the first end 141 of the base 140.

[0165] The wall of the through hole 149 is spaced apart from the screw 190 so that when the screw 190 passes through the through hole 149 to connect the first threaded hole 137 and the second threaded hole 153, the screw 190 can connect the door panel 130 and the shaft cover 150 without connecting to the base 140, so as to avoid the screw 190 and the base 140 from interfering with each other and realizing the mechanical locking of the door panel 130, the base 140 and the shaft cover 150.

[0166] It should be noted that the first fixing part 136 and the second fixing part 152 can also be riveted or snap-fitted together.

[0167] In summary, for reference Figure 9a and Figure 9b The base 140 is integrally connected to the door panel 130 so that the gap between the base 140 and the door panel 130 is fixed, that is, the gap between the first slide groove 160 and the second slide groove 170 defined by the base 140 and the door panel 130. Figure 2a As can be seen, the fit clearance between the first rotating shaft 111 of the first swing arm 110 and the first sliding groove 160, and the fit clearance between the second rotating shaft 121 of the second swing arm 120 and the second sliding groove 170 are all fixed. Thus, the first rotating shaft 111, which is slidably connected to the first sliding groove 160, will not get stuck, and the second rotating shaft 121, which is slidably connected to the second sliding groove 170, will not get stuck either.

[0168] refer to Figures 9a to 9c Furthermore, on the side near the first end 141 of the base 140, the door panel 130 is connected to the shaft cover 150 by screws 190. Figure 6b As can be seen, avoiding the use of adhesive bonding facilitates rework and reduces the difficulty and cost of rework.

[0169] Simultaneously, the first end 141 and the second end 143 of the base 140 are first positioned and engaged with the door panel 130; then, the middle part 142 of the base 140 is fixedly connected to the door panel 130 using screws 190. Figure 6a (As can be seen), and the first end 141 and the second end 143 of the base 140 are mortised and tenoned with the door panel 130 by the first tenon 181 and the second tenon 182. Figure 5a As can be seen, a "door panel-base" module is formed to fix the gap between the door panel 130 and the base 140 in the Z-axis direction (i.e., the second direction, which can also be understood as the thickness direction); finally, the shaft cover 150 is fixedly connected to the above-mentioned "door panel-base" module to play a mechanical locking role.

[0170] The door panel 130 is connected to the base 140 first, and then the shaft cover 150 is installed. Compared with installing three structures (door panel, base and shaft cover) together, this provides installation stability. At the same time, the door panel 130 and the base 140 can be locked together by mortise and tenon joints. Compared with the form of locking with multiple screws, this simplifies the assembly process, improves production efficiency, and is mass-producible.

[0171] Continue to refer to Figure 9c and combined Figure 6b The shaft cover 150 includes a recess 151 for placing the door panel 130 and the base 140. Along the width direction (i.e., the third direction X) of the rotating mechanism 100, both ends of the shaft cover 150 extend away from the center along the thickness direction (i.e., the second direction Z) of the rotating mechanism 100 to form the recess 151.

[0172] The shaft cover 150 also includes two blocking parts 154. For ease of description, the blocking part on the left is named the first blocking part 1540, and the blocking part on the right is named the second blocking part 1541. The first blocking part 1540 and the second blocking part 1541 are spaced apart along the width direction (i.e., the third direction X) of the rotating mechanism.

[0173] refer to Figure 9c and combined Figure 5a and Figure 5bAlong the width direction of the rotating mechanism (i.e., the third direction X), the first blocking part 1540 is disposed opposite to the first tenon 181 to restrict the first tenon 181 from sliding out of the first sub-tenon 1440 or the third sub-tenon 1310, or to restrict the first tenon 181 from sliding out of the first sub-tenon 1440 and the third sub-tenon 1310; the second blocking part 1541 is disposed opposite to the second tenon 182 to restrict the second tenon 182 from sliding out of the second sub-tenon 1441 or the fourth sub-tenon 1311, or to restrict the second tenon 182 from sliding out of the second sub-tenon 1441 and the fourth sub-tenon 1311, affecting the connection between the first end 141 of the base 140 and the door panel 130.

[0174] The shape of the blocking part 154 is not limited in this application embodiment. For example, the embodiment shown in this application shows two first blocking parts 1540 and second blocking parts 1541 that are spaced apart along the width direction (i.e., the third direction X). The first blocking part 1540 and the second blocking part 1541 are connected by a minor arc. Both the first blocking part 1540 and the second blocking part 1541 extend along the thickness direction of the rotating mechanism (i.e., the second direction Z) to a height higher than the tenon 180, and are flush with or slightly lower than the height of the door panel 130.

[0175] In other possible implementations, refer to Figure 9a and Figure 9b Since the first end 141 has sufficient structural space, to reinforce the connection between the base 140 and the door panel 130, the base 140 and the door panel 130 can be mechanically fastened together with screws 190 on the side near the first end 141. Figure 6b visible).

[0176] Specifically, refer to Figure 9a and Figure 9b Along the width direction of the rotating mechanism, third threaded holes 146 (which can be referred to as third fixing parts 145) can be provided at intervals on both sides of the through hole 149. The door panel 130 includes a fourth threaded hole 133 (which can be referred to as fourth fixing part 132) corresponding to the third threaded hole 146. The third threaded hole 146 and the fourth threaded hole 133 are connected by screws 190. Figure 6b (As can be seen). Specifically, when the door panel 130 is assembled with the base 140, the third threaded hole 146 and the fourth threaded hole 133 are arranged opposite each other along the thickness direction of the rotating mechanism (i.e., the second direction Z), and the screw 190 passes through the third threaded hole 146 and the fourth threaded hole 133, so that the side of the base 140 near the first end 141 is fixedly connected to the door panel 130.

[0177] It should be noted that the third fixing part 145 and the fourth fixing part 132 can also be riveted or snap-fitted together.

[0178] Thus, the first end 141 and the second end 143 of the base 140 are mortised and tenoned to the door panel 130. Near the first end 141, the base 140 and the door panel 130 are connected by screws 190. Figure 6b As can be seen, this makes the fixing of the door panel 130 and the base 140 more secure and reliable. However, it is understood that it is also possible to simply make the first end 141 of the base 140 mortise and tenon connected to the door panel 130, without providing the screw 190 connection as described above.

[0179] In other possible implementations, refer to Figure 9a and Figure 9b Since the second end 143 has sufficient structural space, to reinforce the connection between the base 140 and the door panel 130, the base 140 and the door panel 130 can be mechanically fastened together using screws 190 on the side near the second end 143. Figure 6a visible).

[0180] Specifically, refer to Figure 9a and Figure 9b The base 140 has a third threaded hole 146 (which may be referred to as the third fixing part 145) on the side near the second end 143, and the door panel 130 includes a fourth threaded hole 133 (which may be referred to as the fourth fixing part 132) corresponding to the third threaded hole 146. The third threaded hole 146 and the fourth threaded hole 133 are connected by screws 190. Figure 6a (As can be seen). Specifically, when the door panel 130 is assembled with the base 140, the third threaded hole 146 and the fourth threaded hole 133 are arranged opposite each other along the thickness direction of the rotating mechanism (i.e., the second direction Z), and the screw 190 passes through the third threaded hole 146 and the fourth threaded hole 133, so that the base 140 is fixedly connected to the door panel 130 on the side near the second end 143.

[0181] Thus, the second end 143 of the base 140 is mortised and tenoned with the door panel 130, and the side of the base 140 near the second end 143 is connected by screws 190, making the fixation between the door panel 130 and the base 140 more secure and reliable. However, it is understood that it is also possible to only mortise and tenon the second end 143 of the base 140 with the door panel 130, without the screws 190 connection as described above.

[0182] In summary, the rotating mechanism in Embodiment 1 is connected to the door panel 130 by mortise and tenon joints through the first end 141 and the second end 143 of the base 140, replacing the previous screw connection. This ensures the smooth rotation of the first and second swing arms while saving structural space. The shaft cover 150 is fixedly connected to the door panel 130 and the base 140 without introducing other foreign objects such as glue, thus reducing the rework process and difficulty.

[0183] Example 2

[0184] refer to Figure 10 Embodiment 2 describes a mortise and tenon connection between the door panel 130 and the shaft cover 150. The following describes the connection in conjunction with... Figures 10 to 12c Another rotating mechanism provided in Embodiment 2 will be described in detail.

[0185] in, Figure 10 This is a perspective view of the rotating mechanism according to Embodiment 2 of this application, where the first and second swing arms are not shown. Figure 11a This is a perspective view of the door panel in the rotating mechanism of Embodiment 2 of this application; Figure 11b This is a perspective view of the shaft cover in the rotating mechanism of Embodiment 2 of this application. Figure 11c This is a perspective view of the base in the rotating mechanism of Embodiment 2 of this application; Figure 12a This is a simplified structural diagram of the tenon and door panel being integrally formed; Figure 12a Only a simplified structural diagram of the tenon and door panel integrally formed on one side of the width direction of the rotating mechanism in this embodiment is shown; Figure 12b This is a simplified structural diagram of the tenon and the mortise and tenon joint connection between the tenon and the shaft cover, which are integrally formed with the door panel in the embodiments of this application; Figure 12c This is a simplified structural diagram of the tenon and shaft cover integrally formed according to an embodiment of this application. Figure 12c Only a simplified structural diagram of the tenon and shaft cover integrally formed on one side of the width direction of the rotating mechanism in this embodiment is shown.

[0186] Similar to Embodiment 1, the middle portion 142 of the base 140 is connected to the door panel 130 by screws 190, as in Embodiment 1, and will not be described again here. Similarly, in Embodiment 2, the base 140 is connected to the door panel 130 by screws 190 on the side near the second end 143, and on the side near the first end 141, the base 140 is connected to the door panel 130 by screws 190. This structure is the same as other optional embodiments in Embodiment 1, and will not be described again here.

[0187] The difference from Embodiment 1 is that in Embodiment 2, the door panel 130 is mortised and tenoned with the shaft cover 150 on the side near the first end 141 and the second end 143 of the base 140.

[0188] In some possible implementations, the shaft cover 150 may be mortised and tenoned with the door panel 130 only on one side near the first end 141 of the base 140.

[0189] Alternatively, in some possible implementations, the shaft cover 150 may be mortised and tenoned with the door panel 130 only on the side near the second end 143 of the base 140.

[0190] It should be noted that the accompanying drawings of this application only show the side of the first end 141 near the base 140, where the door panels 130 are all mortise and tenon connected to the shaft cover 150. However, it can be understood that the door panels 130 and the shaft cover 150 have the same mortise and tenon structure on the side of the second end 143 near the base 140.

[0191] Specifically, refer to Figure 10 and Figure 11a Along the length of the rotating mechanism, a connector 138 is provided at the position corresponding to the first end 141 of the base 140 and the door panel 130. That is, the connector 138 is located at the front end of the door panel 130 along the length of the door panel 130. Along the width of the door panel 130, the connector 138 (not at the edge of both ends) is provided with two second tenons 131. For ease of description, along the width of the rotating mechanism, the second tenon located on the left is named the third sub-tenon 1310, and the second tenon located on the right is named the fourth sub-tenon 1311. The third sub-tenon 1310 and the fourth sub-tenon 1311 are spaced apart along the width of the rotating mechanism.

[0192] refer to Figure 11a and Figure 11b The blocking portion 154 of the shaft cover 150 has a third tenon 155 disposed opposite to each of the second tenons 131. For ease of description, the tenon corresponding to the third tenon 1310 is called the fifth tenon 1550, and the tenon corresponding to the fourth tenon 1311 is called the sixth tenon 1551. The fifth tenon 1550 and the sixth tenon 1551 are disposed opposite to each other along the width direction of the rotating mechanism. The fifth tenon 1550 is disposed on the side of the first blocking portion 1540 facing the second blocking portion 1541, and the sixth tenon 1551 is disposed on the side of the second blocking portion 1541 facing the first blocking portion 1540.

[0193] When assembling the shaft cover 150 and the door panel 130, the fifth sub-tenon groove 1550 and the third sub-tenon groove 1310 are opposite each other along the length direction Y of the rotating mechanism to form a concave structure, and are connected by the mortise and tenon joint of the third tenon 183 (convex structure). That is, the front end of the third tenon 183 is inserted into the third sub-tenon groove 1310 to achieve the mortise and tenon joint, and the rear end is inserted into the fifth sub-tenon groove 1550 to achieve the mortise and tenon joint.

[0194] Similarly, the sixth sub-mortise 1551 and the fourth sub-mortise 1311 are opposite each other along the length of the rotating mechanism to form a concave structure, and are connected by the fourth tenon 184 (convex structure). That is, the front end of the fourth tenon 184 is inserted into the fourth sub-mortise 1311 to achieve the mortise and tenon connection, and the rear end is inserted into the sixth sub-mortise 1551 to achieve the mortise and tenon connection, so that the shaft cover 150 and the door panel 130 are mortised and tenoned.

[0195] The shape of the third tenon 183 is compatible with the shapes of the fifth mortise 1550 and the third mortise 1310, both being straight. The shape of the fourth tenon 184 is compatible with the shapes of the sixth mortise 1551 and the fourth mortise 1311, both being straight.

[0196] It is understandable that the third tenon 183 between the fifth tenon 1550 and the third tenon 1310 can also be as follows: Figure 7a The cross shape shown, or as Figure 7b The trapezoidal shape shown. The fourth tenon 184 between the sixth sub-tenon 1551 and the fourth sub-tenon 1311 can also be as follows. Figure 7a The cross shape shown, or as Figure 7b The trapezoid shown. Similarly, the shape of the third tenon 183 can be the same as or different from the shape of the fourth tenon 184.

[0197] It should be noted that the specific positions of the second mortise 131 and the third mortise 155 are not limited in the embodiments of this application, and can be as follows: Figure 10 The arrangement shown is opposite each other along the length direction, or it can be as follows: Figure 12a The two structures are arranged opposite each other along the width direction or along the thickness direction, as shown.

[0198] In some possible implementations, reference is made to Figure 12a The third tenon 183 is integrally formed with the connector 138 on the door panel, and the fourth tenon 184 is also integrally formed with the door panel 130 (not shown in the figure). The shape of the third tenon 183 is adapted to the fifth mortise 1550. Figure 12a The figure shows that the third tenon 183 is in the shape of a straight line, and correspondingly, the fifth mortise 1550 is rectangular in shape; similarly, the shape of the fourth tenon 184 is adapted to the shape of the sixth mortise 1551 (not shown in the figure).

[0199] refer to Figure 12a That is, along the width direction of the rotating mechanism, one side of the door panel connector 138 protrudes outward (specifically, protrudes along the X direction towards the fifth tenon 1550) to form a third tenon 183. The shape of this protruding part is adapted to the fifth tenon 1550 and is straight. The other side of the connector 138 protrudes outward to form a fourth tenon 184 (not shown in the figure). The shape of this protruding part is adapted to the sixth tenon 1551. Thus, refer to Figure 12b When assembling the door panel 130 and the shaft cover 150, it is only necessary to insert the third tenon 183 into the fifth sub-mortise 1550 along the length direction of the rotating mechanism, and insert the fourth tenon 184 into the sixth sub-mortise 1551 along the length direction of the rotating mechanism to make the mortise and tenon connection.

[0200] Or, refer to Figure 12c The third tenon 183 is integrally formed with the shaft cover 150, and the fourth tenon 184 is integrally formed with the shaft cover 150 (not shown in the figure). The shape of the third tenon 183 is adapted to the shape of the third mortise 1310, and the shape of the fourth tenon 184 is adapted to the shape of the fourth mortise 1311.

[0201] In other words, along the width direction of the rotating mechanism, one side of the shaft cover 150 protrudes outward (specifically, protrudes along the X direction towards the third mortise 1310) to form the third tenon 183. The shape of this protruding part is adapted to the third mortise 1310 and is straight. The other side of the shaft cover 150 protrudes outward to form the fourth tenon 184 (not shown in the figure). The shape of this protruding part is adapted to the fourth mortise 1311. Thus, when assembling the door panel 130 and the shaft cover 150, it is only necessary to insert the third tenon 183 into the third mortise 1310 along the length direction of the rotating mechanism, and insert the fourth tenon 184 into the fourth mortise 1311 along the length direction of the rotating mechanism to achieve the mortise and tenon connection.

[0202] It is understandable that the third tenon 183 and the shaft cover 150 could be integrally formed, and the fourth tenon 184 could be integrally formed with the door panel 130; or the third tenon 183 and the door panel 130 could be integrally formed, and the fourth tenon 184 and the shaft cover 150 could be integrally formed; or only the third tenon 183 and the door panel 130 could be integrally formed, and the fourth tenon 184 could be set separately; or only the fourth tenon 184 and the door panel 130 could be integrally formed, and the third tenon 183 could be set separately; or only the third tenon 183 and the shaft cover 150 could be integrally formed, and the fourth tenon 184 could be set separately; or only the fourth tenon 184 and the shaft cover 150 could be integrally formed, and the third tenon 183 could be set separately.

[0203] At the second end 143 near the base 140, the shaft cover 150 and the door panel 130 have the same mortise and tenon structure as described above, which will not be repeated here.

[0204] Continue to refer to Figures 11a to 11c Because on the side near the first end 141 of the base 140, the second tenon 131 of the door panel 130 and the third tenon 155 of the shaft cover 150 are mortised and tenoned together by the third tenon 183 and the fourth tenon 184. Figure 10 As can be seen, there is sufficient structural space at this location for mounting screws 190 to mechanically fasten the base 140 to the door panel 130 (in combination). Figure 6b (As can be seen). For specific connection methods, please refer to other possible implementation methods in Embodiment 1.

[0205] Similarly, on the side near the second end 143 of the base 140, the connection between the base 140 and the door panel 130 is as described in other possible embodiments in Embodiment 1, and will not be repeated here.

[0206] In summary, on the side near the first end 141 of the base 140, the base 140 is connected to the door panel 130 by screws 190; on the side near the second end 143, the base 140 is connected to the door panel 130 by screws 190; and the middle part 142 of the base 140 is connected to the door panel 130 by screws 190.

[0207] In other words, the gap between the base 140 and the door panel 130 is fixed, meaning the gap between the first slide groove 160 and the second slide groove 170 defined by the base 140 and the door panel 130 will not change. Therefore, the fitting clearance between the first rotating shaft 111 and the first slide groove 160, and the fitting clearance between the second rotating shaft 121 and the second slide groove 170 are both fixed. Figure 2a As can be seen, the first rotating shaft 111, which is slidably connected to the first sliding groove 160, will not jam, nor will the second rotating shaft 121, which is slidably connected to the second sliding groove 170, jam.

[0208] In addition, the door panel 130 and the shaft cover 150 are connected by mortise and tenon joints, avoiding the use of glue connection, which facilitates repair and reduces the difficulty and cost of repair.

[0209] Furthermore, firstly, on one side near the first end 141 and the second end 143 of the base 140, the shaft cover 150 and the door panel 130 are mortised and tenoned together using the third tenon 183 and the fourth tenon 184. Figure 10 As can be seen, a "door panel-shaft cover" module is formed, and then the base 140 is inserted between the door panel 130 and the shaft cover 150, and the base 140 is fixedly connected to the door panel 130 to play the role of mechanical locking.

[0210] The door panel 130 is connected to the shaft cover 150 first, and then the base 140 is installed. Compared with installing three structures (door panel, base and shaft cover) together, this provides installation stability. At the same time, the door panel 130 and shaft cover 150 can be locked together by mortise and tenon joints. Compared with the form of locking with multiple screws, this simplifies the assembly process, improves production efficiency, and is suitable for mass production.

[0211] In other possible embodiments, since the door panel 130 and the axle cover 150 are mortised and tenoned at the first end 141 of the base 140, there is sufficient structural space there for mounting screws 190 to mechanically lock the axle cover 150 to the door panel 130 again. Figure 6b (As can be seen). For specific locking methods, please refer to Example 1.

[0212] Example 3

[0213] In other embodiments, reference is made to Figure 13 Embodiment 3 describes the mortise and tenon connection between the base 140 and the shaft cover 150. The following describes the connection in conjunction with... Figures 13 to 15c A detailed description of a rotating mechanism provided in Embodiment 3 is given below.

[0214] in, Figure 13 This is a perspective view of the rotating mechanism according to Embodiment 3 of this application, where the first and second swing arms are not shown. Figure 14a This is a perspective view of the base according to Embodiment 3 of this application; Figure 14b This is a perspective view of the shaft cover according to Embodiment 3 of this application; Figure 14c This is a perspective view of the door panel according to Embodiment 3 of this application; Figure 15a This is a simplified structural diagram showing the tenon and base being integrally formed; Figure 15a Only a simplified structural diagram of the tenon and base integrally formed on one side of the width direction of the rotating mechanism in this embodiment is shown; Figure 15b This is a simplified structural diagram of the tenon and the mortise and tenon joint connection between the tenon and the shaft cover, which are integrally formed with the base in the embodiment of this application; Figure 15c This is a simplified structural diagram of the tenon and shaft cover integrally formed according to an embodiment of this application. Figure 15c Only a simplified structural diagram of the tenon on one side of the width direction of the rotating mechanism in this embodiment of the application and the structure integrally formed with the shaft cover is shown.

[0215] Similar to Embodiment 1, the middle portion 142 of the base 140 is connected to the door panel 130 by screws 190. Similarly, in Embodiment 3, the base 140 is connected to the door panel 130 by screws 190 on the side near the second end 143, and on the side near the first end 141. This structure is the same as other optional embodiments in Embodiment 1, and will not be described again here.

[0216] The difference from Embodiment 1 is that in Embodiment 3, the base 140 is mortised and tenoned with the shaft cover 150 at the first end 141 and the second end 143 of the base 140.

[0217] In some possible implementations, the shaft cover 150 may be mortised and tenoned to the base 140 only at the first end 141 of the base 140.

[0218] Alternatively, in some possible implementations, the shaft cover 150 may be mortised and tenoned to the base 140 only at the second end 143 of the base 140.

[0219] It should be noted that the accompanying drawings of this application only show the first end 141 of the base 140, where the base 140 and the shaft cover 150 are connected by mortise and tenon joints. However, it can be understood that at the second end 143 of the base 140, the base 140 and the shaft cover 150 have the same mortise and tenon structure.

[0220] Specifically, refer to Figure 13 and Figure 14a The first end 141 of the base 140 has two first tenons 144. For ease of description, the one on the left is named the first sub-tenon 1440 and the one on the right is named the second sub-tenon 1441 along the width direction of the rotating mechanism. The first sub-tenon 1440 and the second sub-tenon 1441 are arranged opposite to each other along the width direction of the rotating mechanism.

[0221] refer to Figure 14a and Figure 14b The two ends of the shaft cover 150 have a third tenon 155 that is arranged opposite to each of the second tenons 131. For ease of description, the tenon corresponding to the third tenon 1310 is called the fifth tenon 1550, and the tenon corresponding to the fourth tenon 1311 is called the sixth tenon 1551. The fifth tenon 1550 and the sixth tenon 1551 are arranged opposite to each other along the width direction of the rotating mechanism.

[0222] When assembling the shaft cover 150 and the base 140, the fifth sub-tenon groove 1550 and the first sub-tenon groove 1440 are opposite each other along the width direction of the rotating mechanism to form a concave structure, and are connected by a tenon (convex structure) through a fifth tenon. That is, the right end of the fifth tenon (not shown in the figure) is inserted into the first sub-tenon groove 1440 to achieve a tenon connection, and the left end is inserted into the fifth sub-tenon groove 1550 to achieve a tenon connection.

[0223] Similarly, the sixth sub-tenon 1551 and the second sub-tenon 1441 are opposite each other along the width direction of the rotating mechanism to form a concave structure, and are mortised and tenoned together by the sixth tenon (convex structure). That is, the left end of the sixth tenon (not shown in the figure) is inserted into the second sub-tenon 1441, and the right end is inserted into the second sub-tenon 1441, so that the shaft cover 150 is mortised and tenoned together with the base 140.

[0224] The shape of the fifth tenon (not shown in the figure) matches the shapes of the fifth mortise 1550 and the first mortise 1440, both being straight. The shape of the sixth tenon (not shown in the figure) matches the shapes of the sixth mortise 1551 and the second mortise 1441, both being straight.

[0225] It is understandable that the fifth tenon between the fifth tenon groove 1550 and the first tenon groove 1440 can also be as follows: Figure 7a The cross shape shown, or as Figure 7b The trapezoidal shape shown. The sixth tenon between the sixth tenon groove 1551 and the second tenon groove 1441 can also be as follows. Figure 7a The cross shape shown, or as Figure 7b The trapezoid is shown. Similarly, the shape of the fifth tenon can be the same as or different from that of the sixth tenon.

[0226] It should be noted that the specific positions of the first mortise 144 and the third mortise 155 are not limited in the embodiments of this application, and can be as follows: Figure 14a and Figure 14b The arrangement shown can be either relative to each other along the width direction or relative to each other along the length direction.

[0227] In some possible implementations, reference is made to Figure 15a The fifth tenon 185 is integrally formed with the base 140, and the sixth tenon is integrally formed with the base 140 (not shown in the figure). The shape of the fifth tenon 185 is adapted to the fifth mortise 1550. Figure 15a The fifth tenon 185 is shown to be in the shape of a straight line, and correspondingly, the fifth mortise 1550 is rectangular in shape; similarly, the shape of the sixth tenon matches the shape of the sixth mortise 1551.

[0228] refer to Figure 15a That is, along the width direction of the rotating mechanism, one side of the base 140 protrudes outward (specifically, protrudes along the X direction towards the fifth tenon 1550) to form the fifth tenon 185. The shape of this protruding part is adapted to the fifth tenon 1550 and is straight. The other side of the base 140 protrudes outward to form the sixth tenon (not shown in the figure). The shape of this protruding part is adapted to the sixth tenon 1551. Thus, refer to... Figure 15b When assembling the shaft cover 150 and the base 140, it is only necessary to insert the fifth tenon 185 into the fifth sub-tenon groove 1550 along the width direction of the rotating mechanism, and insert the sixth tenon into the sixth sub-tenon groove 1551 along the width direction of the rotating mechanism to perform the mortise and tenon connection.

[0229] Or, refer to Figure 15c The fifth tenon 185 is integrally formed with the shaft cover 150, and the sixth tenon is integrally formed with the shaft cover 150 (not shown in the figure). The shape of the fifth tenon 185 is adapted to the shape of the first sub-mortise 1440, and the shape of the sixth tenon is adapted to the shape of the second sub-mortise 1441.

[0230] In other words, along the width direction of the rotating mechanism, one side of the shaft cover 150 protrudes outward (specifically, protrudes along the X direction towards the first mortise 1440) to form a fifth tenon 185. The shape of this protruding part is adapted to the first mortise 1440 and is straight. The other side of the shaft cover 150 protrudes outward to form a sixth tenon (not shown in the figure). The shape of this protruding part is adapted to the second mortise 1441. Thus, when assembling the base 140 and the shaft cover 150, it is only necessary to insert the fifth tenon 185 into the first mortise 1440 along the width direction of the rotating mechanism and insert the sixth tenon into the second mortise 1441 along the width direction of the rotating mechanism to achieve a mortise and tenon connection.

[0231] It is understandable that the fifth tenon and the shaft cover 150 could be integrally formed, and the sixth tenon and the base 140 could be integrally formed; or the fifth tenon and the base 140 could be integrally formed, and the sixth tenon and the shaft cover 150 could be integrally formed; or only the fifth tenon and the shaft cover 150 could be integrally formed, and the sixth tenon could be set separately; or only the sixth tenon and the shaft cover 150 could be integrally formed, and the fifth tenon could be set separately; or only the fifth tenon and the base 140 could be integrally formed, and the sixth tenon could be set separately; or only the sixth tenon and the base 140 could be integrally formed, and the fifth tenon could be set separately.

[0232] At the second end 143 of the base 140, the shaft cover 150 and the base 140 have the same tenon and mortise structure as described above, which will not be repeated here.

[0233] Continue to refer to Figures 14a to 14c Since the base 140 is mortised and tenoned with the bushing 150 at its first end 141, there is sufficient structural space at that location for mounting screws 190 to mechanically lock the base 140 to the door panel 130. Figure 6b (As can be seen). For specific connection methods, please refer to other possible implementation methods in Embodiment 1.

[0234] Similarly, at the second end 143 of the base 140, the connection between the base 140 and the door panel 130 is as described in other possible embodiments in Embodiment 1, and will not be repeated here.

[0235] In summary, on the side near the first end 141 of the base 140, the base 140 is connected to the door panel 130 by screws 190. Figure 6b As can be seen, on the side near the second end 143, the base 140 is connected to the door panel 130 by screws 190. Figure 6a As can be seen, the middle part 142 of the base 140 is connected to the door panel 130 by screws 190. Figure 6aAs can be seen, the gaps between the base 140 and the door panel 130 are fixed, meaning the gaps between the first slide groove 160 and the second slide groove 170 defined by the base 140 and the door panel 130 will not change. Therefore, the fitting clearance between the first rotating shaft 111 and the first slide groove 160, and the fitting clearance between the second rotating shaft 121 and the second slide groove 170 are also fixed. Figure 2a As can be seen, the first rotating shaft 111, which is slidably connected to the first sliding groove 160, will not jam, nor will the second rotating shaft 121, which is slidably connected to the second sliding groove 170, jam.

[0236] Meanwhile, the base 140 and the shaft cover 150 are connected by mortise and tenon joints, avoiding the use of glue joints, which facilitates repair and reduces the difficulty and cost of repair.

[0237] Simultaneously, at the first end 141 and the second end 143 of the base 140, the shaft cover 150 is mortised and tenoned with the base 140 using the fifth tenon 185 and the sixth tenon. Figure 15a As can be seen, a "base-shaft cover" module is formed, and then the door panel 130 is fixedly connected to the base 140 to play the role of mechanical locking.

[0238] The base 140 and the axle cover 150 are connected first, and then the door panel 130 is installed. Compared with installing three structures (door panel, base and axle cover) together, this provides installation stability. At the same time, the door panel 130 and the axle cover 150 can be locked together by mortise and tenon joints. Compared with the form of locking with multiple screws, this simplifies the assembly process, improves production efficiency, and is mass-producible.

[0239] In other possible embodiments, since the door panel 130 and the axle cover 150 are mortised and tenoned at the first end 141 of the base 140, there is sufficient structural space there for mounting screws 190 to mechanically lock the axle cover 150 to the door panel 130. Figure 6b (As can be seen). For specific locking methods, please refer to Example 1.

[0240] refer to Figures 16a to 16d In other embodiments, the connection relationship of the aforementioned rotating mechanism 100 can also be that the base 140, the shaft cover 150, and the door panel 130 are connected by mortise and tenon joints. Figures 16a to 16d Only the left side of door panel 130, base 140 and shaft cover 150 is shown.

[0241] Specifically, refer to Figure 16a The door panel 130 and the base 140 are mortised and tenoned along the width direction, and the base 140 and the shaft cover 150 are mortised and tenoned along the width direction. Figure 16b In the middle, the fifth tenon 185 is integrally formed with the base 140. (Reference) Figure 16cThe fifth tenon 185 is integrally formed with the shaft cover 150. Figure 16d In the middle, the first tenon 181 is integrally formed with the door panel 130, and the fifth tenon 185 is integrally formed with the shaft cover 150.

[0242] In summary, the rotating mechanism in the folding phone of this application embodiment uses mortise and tenon joints to connect at least two of the base end, door panel, and shaft cover, saving some screw space. Other unconnected structures are then connected with screws. This ensures a fixed fit clearance between the Z-axis swing arm and the slide groove, reducing the possibility of the swing arm jamming. Simultaneously, it avoids introducing foreign matter such as adhesive, reducing the cost and difficulty of rework. Furthermore, it allows for adjustment of the assembly sequence, ensuring assembly stability.

[0243] Example 4

[0244] This application embodiment also provides a rotating mechanism, which includes: a first part (not shown) and a second part (not shown), the second part being tenon-jointed with the first part, and the first part and the second part jointly defining a groove (not shown); one end of the rotating part is slidably connected to the groove so that the rotating part rotates about a third axis, the third axis being parallel to the first direction, wherein the number of grooves may include one or more.

[0245] Using the above technical solution, the embodiments of this application use a mortise and tenon joint between the first part and the second part to achieve mechanical locking and mutual positioning of the first part and the second part.

[0246] For example, this rotating structure can be applied to devices such as laptop hinges and headphone (e.g., wireless headphone) charging cases that require control over the consistency of rotation along the hinge direction and the gap between the two sides of the hinge when closed.

[0247] For example Figure 17a , Figure 17a A perspective view of an earphone charging case 500 is shown. The earphone 500 includes an earphone case 501, a lid 502, and the aforementioned rotating mechanism 100. The earphone case 501 has an earphone receiving cavity 5011 for holding wireless earphones (not shown). When the earphones are placed in the earphone receiving cavity 5011 and the lid 502 is closed, the earphones can be charged. The rotating part of the rotating mechanism 100 is, for example, the lid 502, which rotates about a third axis parallel to the first direction Y.

[0248] For example, refer to Figure 17b , Figure 17bA perspective view of a laptop computer 600 is shown. The laptop computer 600 includes a keyboard 601, a display screen 602, and the aforementioned rotation mechanism 100. The rotating part of the rotation mechanism 100 is, for example, the display screen 602, which rotates about a third axis parallel to the first direction Y.

[0249] This application embodiment uses a mortise and tenon joint to connect the first part and the second part, thereby fixing the fit clearance between the groove formed by the first part and the second part and the rotating part, preventing jamming. The specific structure of the first and second parts in this rotating mechanism is not limited; any structure capable of forming a groove falls within the protection scope of this application embodiment (e.g., the two structures forming the groove in a laptop or headphone charging case).
