The terminal device comprises a rotating shaft mechanism 100, a display screen 200 and two sub-machine bodies 300, wherein the sub-machine bodies 300 are used for bearing the display screen 200, and the rotating shaft mechanism 100 is arranged at the joint of the two sub-machine bodies 300, so that the two sub-machine bodies 300 can be switched between an unfolded state (shown in figure 1) and a folded state (shown in figure 4).
Of course, the above terminal device is not limited to the two sub-bodies 300, and more than two sub-bodies 300, such as three, four, etc., may be provided, and the spindle mechanism 100 may be provided at the junction of two adjacent sub-bodies 300 according to the actual situation.
As shown in fig. 1 and fig. 3, each sub-body 300 is a shell structure, for example, the sub-body 300 may be a middle frame, the sub-body 300 includes a body bottom wall 310 (also referred to as a "cover plate") and a body side wall 320 disposed at an edge of the body bottom wall 310, the body bottom walls 310 and the body side walls 320 of the two sub-bodies 300 together enclose a setting space 330, the display screen 200 is disposed in the setting space 330, and the display screen 200 itself has a bendable property and can be bent and deformed under the action of an external force.
As shown in fig. 1 and 3, when the two sub-bodies 300 are in the unfolded state, the display screen 200 is unfolded, and the display area of the display screen 200 is exposed to facilitate the display of image information to the user. The display screen 200 includes a first display area 210, a second display area 220, and a third display area 230. The first display area 210 covers the bottom wall 310 of one sub-body 300, the second display area 220 covers the bottom wall 310 of the other sub-body 300, and the third display area 230 covers the rotating shaft mechanism 100.
The display 200 may be all flexible, such as the first display area 210, the second display area 220, and the third display area 230 of the display 200 are all flexible; the display 200 may have a flexible screen structure in the middle folded portion and a hard screen structure on both sides, such as the first display area 210 and the second display area 220 of the display 200 are hard screen structures and the third display area 230 is a flexible screen structure.
As shown in fig. 4 and 5, when the two sub-bodies 300 are in a folded state, the two sub-bodies 300 are stacked, and the display screen 200 is folded between the two sub-bodies 300 at this time, which can facilitate the carrying of the terminal device. The first display area 210 and the second display area 220 of the display screen 200 are stacked, where "stacking" means that the first display area 210 and the second display area 220 are stacked in the thickness direction, and the thickness directions of the first display area 210 and the second display area 220 are parallel or substantially parallel (for example, the deviation is within 30 °), where the first display area 210 and the second display area 220 may be attached together, or a gap is formed between the first display area 210 and the second display area 220, which is not limited herein specifically.
As shown in fig. 5, when the two sub-bodies 300 are in the folded state, the third display area 230 may be folded in a droplet shape, and in this shape, the third display area 230 includes a circular arc section 233, a first transition section 231, and a second transition section 232. The first transition section 231 is connected between the circular arc section 233 and the first display area 210.

It is understood that when the two sub-bodies 300 are in the folded state, the third display area 230 of the display screen 200 may be folded into other shapes according to actual needs, which is not limited by the present application.
As shown in fig. 3 and 5, the spindle mechanism 100 includes a spindle cover 1, and the spindle cover 1 is used as an external part (i.e., an externally visible part) of the spindle mechanism 100 for covering a moving part (not shown) in the spindle mechanism 100, so as to prevent the movement of the moving part in the spindle mechanism 100 from being disturbed by the outside. As shown in fig. 3 and 5, the two sub-bodies 300 are provided with overlapping parts 340 at the joints, the overlapping parts 340 are in a step shape, and as shown in fig. 3, when the two sub-bodies 300 are in a unfolded state, the shaft cover 1 is positioned in a containing groove 350 formed by the two overlapping parts 340, the shaft cover 1 is shielded by the overlapping parts 340, and the shaft cover 1 is not seen from the outside, so that the appearance of the joint of the two sub-bodies 300 of the terminal equipment is ensured when the terminal equipment is in the unfolded state; when the two sub-bodies 300 move from the unfolded state to the folded state, the two overlapping portions 340 are gradually opened, and the shaft cover 1 is gradually exposed from between the two overlapping portions 340; as shown in fig. 4 and 5, when the two sub-bodies 300 are in the folded state, the shaft cover 1 is positioned in the gap 360 formed by the two overlap portions 340 and covers the gap 360, thereby preventing the moving parts of the rotation shaft mechanism 100 in the gap 360 from being seen from the outside, and thus ensuring the appearance of the junction of the two sub-bodies 300 when the terminal device is in the folded state.
Wherein, as shown in fig. 3, when the two sub-bodies 300 are in the unfolded state, the position of the shaft cover 1 in the receiving groove 350 directly affects the thickness of the terminal device. In a hinge mechanism of a terminal device in the related art, when two sub-bodies 300 are in an unfolded state, a position of a hinge cover 1 is close to a bottom wall of a receiving groove 350, and in a case that a connection position of the hinge mechanism 100 and the sub-bodies 300 is unchanged, a dimension of the hinge mechanism 100 in a thickness direction Z of the terminal device is larger, and the terminal device needs to be designed to be thicker to receive the hinge mechanism 100, thereby being disadvantageous for lightening and thinning of the terminal device.
For this reason, an embodiment of the present application provides a rotating shaft mechanism to solve the above-mentioned problems, as shown in fig. 6 and 7, fig. 6 is a schematic diagram of the terminal device in the folded state in the first embodiment of the present application, and fig. 7 is a schematic diagram of the terminal device in the unfolded state in the first embodiment of the present application.
The rotating shaft mechanism comprises a base 2, a shaft cover 1, an elastic part 3 and a swing arm 4.
The base 2 (which may also be referred to as a spindle base) is used to support a portion of the display screen 200, and in particular, the base 2 is used to support a third display area of the display screen 200 of the terminal device shown in fig. 1.
The shaft cover 1 is disposed on the back side of the base 2 (i.e., the side of the base 2 away from the display screen 200, such as the lower side shown in fig. 6); in some embodiments, as shown in fig. 6, the shaft cover 1 includes a shaft cover wall 11, where the shaft cover wall 11 encloses a receiving space 12, and as shown in fig. 6, the shaft cover wall 11 includes a shaft cover bottom wall 13, and a shaft cover side wall 14 disposed at a periphery of the shaft cover bottom wall 13, where the shaft cover bottom wall 13 and the shaft cover side wall 14 enclose a receiving space 12, and the receiving space 12 may be a U-shaped groove, but not limited to this, and the receiving space 12 may also be a trapezoid-shaped groove, a semicircular groove, an arc-shaped groove, and the like. In addition to the above-described structure, the shaft cover wall 11 may be designed as a flat plate structure, which may be provided according to actual circumstances.
In some embodiments, as shown in fig. 6, the elastic member 3 is connected between the base 2 and the shaft cover 1, and is configured to apply an elastic force to the shaft cover 1 that can move the shaft cover 1 in a direction approaching the base 2. Specifically, the elastic member 3 is a spring that is in a stretched state, thereby applying an elastic force to the shaft cover 1 that moves in a direction approaching the base 2. By arranging the elastic member 3 as a spring, the occupied space of the elastic member 3 is small and the elastic force provided is large.
The elastic member 3 may be provided in one or more pieces, and is not particularly limited. The elastic member 3 may be a spring plate or a device including a spring, in addition to the spring, and the elastic member 3 may be specific according to the actual situation.
In some embodiments, as shown in fig. 6, the swing arm 4 is slidably connected to the sub-body 300, for example, a sliding fit portion b is provided on the swing arm 4, a groove a is provided on the sub-body 300, and the sliding fit portion b is slidably fitted in the groove a, and the sliding fit portion b may have a plate shape, a column shape, a sphere shape, or the like, which is not limited herein. The sliding connection between the swing arm 4 and the sub-body 300 is to make the degree of freedom of the mechanism formed by the sub-body 300, the base 2 and the swing arm 4 be 1, so as to ensure that the two sub-bodies 300 can be unfolded and folded smoothly, and avoid the problems of deflection of the display screen 200 and the like in the folding and unfolding process.
In some embodiments, as shown in fig. 6, the number of the swing arms 4 is two, the two swing arms 4 are symmetrically disposed on two opposite sides of the base 2 along the width direction X of the shaft cover 1, the two swing arms 4 are respectively slidably connected with the two sub-bodies 300, and the two swing arms 4 are both rotatably connected to the base 2. As shown in fig. 7, when the two sub-bodies 300 are in the unfolded state, both swing arms 4 are located at the unfolded positions; as shown in fig. 6, when the two sub-bodies 300 are in the folded state, both swing arms 4 are located at the folded position. When the two sub-bodies 300 are switched to the folded state, the swing arm 4 correspondingly rotates to the folded position relative to the base 2, and when the two sub-bodies 300 are switched to the unfolded state, the swing arm 4 correspondingly rotates to the unfolded position relative to the base 2.
In some embodiments, as shown in fig. 6, the swing arm 4 is rotatably connected to the base 2 through a rotation shaft 6, and the swing arm 4 is relatively fixed to the rotation shaft 6 in the circumferential direction of the rotation shaft 6. The swing arm 4 is connected with a pressing member 5, specifically, as shown in fig. 6, a gear 71 is fixedly sleeved on the rotating shaft 6, the pressing member 5 is a rack and extends along a first direction Z, the pressing member 5 is meshed with the gear 71 and is also slidably connected with the base 2, for example, as shown in fig. 6, a sliding connection hole 20 is formed in the base 2, and the pressing member 5 is slidably matched with the sliding connection hole 20. The end of the pressing member 5 near the shaft cover 1 is a connecting portion 51, and the connecting portion 51 is abutted against the shaft cover 1.
The first direction Z is perpendicular to both the width direction X of the shaft cover 1 and the length direction Y of the shaft cover 1, and the Z direction may be regarded as a depth direction of the accommodating space 12, that is, a direction perpendicular to the display surface of the display screen 200 when the display screen 200 is unfolded into a flat surface.
Of course, the extending direction of the pressing member 5 may also be at an angle to the first direction Z, for example, within 5 °; the above-mentioned swing arm 4 may be directly connected to the pressing member 5, for example, by integrating the swing arm 4 with the gear 71, instead of indirectly connected to the pressing member 5 via the gear 71, so that the direct connection of the swing arm 4 to the pressing member 5 is achieved.
The process of folding and unfolding the terminal device of the present application is described below with reference to the swing arm 4 and the sub-body 300 located on the left side in fig. 6 and 7:
as shown in fig. 6, in the process of switching the two sub-bodies 300 to the folded state, the swing arm 4 rotates clockwise with the sub-bodies 300 (i.e., rotates to the folded position relative to the base 2), and the rotating shaft 6 drives the gear 71 to rotate clockwise, the pressing member 5 moves downward (may be referred to as "forward") under the drive of the gear 71, so that the connecting portion 51 moves away from the base 2 and applies a force to the shaft cover 1, so that the connecting portion of the shaft cover 1 moves in a direction away from the base 2, thereby realizing "lowering" of the shaft cover 1.
As shown in fig. 7, in the process of switching the two sub-bodies 300 to the folded state, the swing arm 4 rotates counterclockwise along with the sub-bodies 300 (i.e., rotates toward the unfolded position relative to the base 2), and the rotating shaft 6 drives the gear 71 to rotate counterclockwise, so that the pressing member 5 moves upward (may be referred to as "reverse") under the driving of the gear 71, and the connecting portion 51 approaches the base 2, at this time, the pressing member 5 no longer applies an acting force to the shaft cover 1, and the shaft cover 1 moves toward the direction approaching the base 2 under the action of the elastic force of the elastic member, thereby realizing "lifting" of the shaft cover 1.
So designed, in the process of unfolding the terminal equipment, the shaft cover 1 can be close to the base 2 under the action of the elastic force of the elastic piece, so that the shaft cover 1 can be lifted, the size of the rotating shaft mechanism in the thickness direction Z of the display screen 200 can be reduced, the occupation of the rotating shaft mechanism on the inner space of the sub-machine body 300 is reduced, and the sub-machine body 300 can be designed to be thinner while the rotating shaft mechanism is accommodated, so that the thinning of the terminal equipment is facilitated.
In addition, in the process of unfolding the terminal equipment, the elastic force of the elastic component 3 also plays a role of helping to reduce the force required for unfolding the two sub-bodies 300, so that the process of unfolding the two sub-bodies 300 by a user is more labor-saving.
Wherein, the movement of the shaft cover 1 in the direction approaching the base 2 means that the movement of the shaft cover 1 decreases the distance between the base 2 and the shaft cover 1 (such as the distance between the base 2 and the shaft cover bottom wall 13 in fig. 6). Movement of the shaft cover 1 in a direction away from the base 2 means that movement of the shaft cover 1 increases the distance between the base 2 and the shaft cover 1. With the base 2 as a positional reference, the shaft cover 1 moves in a direction approaching the base 2, that is, moves upward based on the positional relationship shown in fig. 6. The shaft cover 1 moves away from the base 2, i.e. is lowered. Wherein the lifting movement as well as the lowering movement of the shaft cover 1 may be movements in the first direction Z.
Of course, the track of the rising movement or the falling movement of the shaft cover 13 is not limited to being parallel to the first direction Z, and may be inclined at an angle, such as within 10 °, with respect to the first direction Z. When the track of the upward movement or the downward movement of the shaft cover 13 is inclined at an angle of less than 5 ° with respect to the first direction Z, the shaft cover 13 may be considered to move in the first direction Z.
In some embodiments, as shown in fig. 6, the number of the pressing pieces 5 is two, and each swing arm 4 is connected to one pressing piece 5, so that, in the process of switching the two sub-bodies 300 to the folded state, the two swing arms 4 are connected to the shaft cover 1 through the pressing pieces 5, respectively, to enable the shaft cover 1 to move downwards. In this way, the stress of the shaft cover 1 is balanced during movement, so that the lower movement of the shaft cover 1 is stable. Furthermore, in other embodiments, a pressing element 5 may be provided, which pressing element 5 is connected to a swing arm 4, so that the shaft cover 1 can also be moved downward by means of a pressing element 5 when the swing arm 4 is rotated from the folded position into the unfolded position.
In some embodiments, as shown in fig. 6, the shaft cover 1 is slidably connected to the base 2 along the first direction Z (i.e., there is a sliding constraint between the shaft cover 1 and the base 2 in the first direction Z), for example, as shown in fig. 6, a guide post 191 is disposed on the shaft cover 1, the guide post 191 extends along the first direction Z, a guide hole 21 is disposed on the base 2, and the guide post 191 is slidably engaged with the guide hole 21. By the design, the shaft cover 1 can be prevented from shaking in the ascending and descending processes, so that the shaft cover 1 moves more stably.
As shown in fig. 8 and 9, fig. 8 is a schematic diagram of a terminal device in a folded state in a second embodiment of the present application, and fig. 9 is a schematic diagram of a terminal device in an unfolded state in a second embodiment of the present application, where the terminal device in the second embodiment is different from the terminal device in the first embodiment in terms of the structure of the pressing member 5 and the movement manner of the pressing member 5 by the swing arm 4 (the movement manner of the pressing member 5 in the second embodiment is swinging, and the movement manner of the pressing member 5 in the first embodiment is moving).
In the second embodiment, the swing arm 4 is rotatably connected with the base 2 through the rotating shaft 6, in the circumferential direction of the rotating shaft 6, the swing arm 4 is relatively fixed with the rotating shaft 6, the pressing member 5 is a cam, the profile of the cam is elliptical, one end part of the cam along the long axis direction of the cam is a connecting part 51, and the other end part of the cam is fixedly sleeved on the rotating shaft 6.
The process of folding and unfolding the terminal device of the present application is described below with reference to the swing arm 4 and the sub-body 300 located on the left side in fig. 8 and 9:
as shown in fig. 8, in the process of switching the two sub-bodies 300 to the folded state, the swing arm 4 rotates clockwise (i.e., rotates toward the folded position relative to the base 2) with the sub-bodies 300, and the rotation shaft 6 drives the pressing piece 5 to swing clockwise (also referred to as "forward"), so that the connection portion 51 is away from the base 2 and applies a force to the shaft cover 1 to move the shaft cover 1 in a direction away from the base 2, thereby achieving "lowering" of the shaft cover 1.
As shown in fig. 9, in the process of switching the two sub-bodies 300 to the folded state, the swing arm 4 rotates counterclockwise along with the sub-bodies 300 (i.e., rotates toward the unfolded position relative to the base 2), and the rotating shaft 6 drives the pressing member 5 to swing counterclockwise, so that the connecting portion 51 approaches the base 2, at this time, the pressing member 5 no longer applies a force to the shaft cover 1, and the shaft cover 1 moves toward the direction approaching the base 2 under the action of the elastic force of the elastic member, so as to realize "lifting" of the shaft cover 1.
In this embodiment, the swing arm 4 drives the pressing member 5 to swing, so that the structure formed by the swing arm 4 and the pressing member 5 is simpler, and no complex transmission component is needed, thereby being beneficial to reducing the design and manufacturing cost of the rotating shaft mechanism.
In some embodiments, as shown in fig. 9, the swing arm 4 abuts against an edge of the shaft cover 1 when in the deployed position to prevent the shaft cover 1 from moving in a direction approaching the base 2. Therefore, the swing arm 4 plays a limiting role, and can limit the moving distance of the shaft cover 1 in the direction close to the base 2, so that other limiting structures are not required to be additionally arranged to limit the moving distance of the shaft cover 1, thereby being beneficial to reducing the design and manufacturing cost of the rotating shaft mechanism.
Of course, the pressing member 5 in the second embodiment may be replaced by an eccentric disc, and the circumferential surface of the eccentric disc, which is used for abutting against the shaft cover 1, is provided with a connecting portion 51, so that the shaft cover 1 can be "lifted" when the swing arm 4 moves to the extended position.
As for other structures in the second embodiment, such as the structure of the swing arm 4, the sub-body 300, the base 2, and the shaft cover 1, and the connection relationship thereof, reference may be made specifically to the arrangement in the first embodiment, and will not be described herein.
As shown in fig. 10 and 11, fig. 10 is a schematic diagram of a terminal device in a folded state in a third embodiment of the present application, and fig. 11 is a schematic diagram of a terminal device in an unfolded state in a third embodiment of the present application, where a main difference between the terminal device in the third embodiment and the terminal device in the second embodiment is that a connection position of the pressing member 5 and the swing arm 4 is different.
In the third embodiment, the pressing member 5 has opposite ends, and one end of the pressing member 5 is fixedly connected with the middle portion of the swing arm 4, and the other end of the pressing member 5 is the connecting portion 51.
The middle part of the swing arm 4 refers to a part except for two end parts of the swing arm 4, and the two end parts of the swing arm 4 specifically refer to two end parts of the swing arm 4 respectively connected with the sub-body 300 and the base 2. The pressing member 5 may be a rod-like structure, a plate-like structure, a frame-like structure, or the like, and is not particularly limited herein. The pressing member 5 and the swing arm 4 may be an integral structure or may be a separate design, and are not particularly limited herein.
The process of folding and unfolding the terminal device of the present application is described below with reference to the swing arm 4 and the sub-body 300 located on the left side in fig. 10 and 11:
as shown in fig. 10, in the process of switching the two sub-bodies 300 to the folded state, the swing arm 4 rotates clockwise (i.e., rotates toward the folded position relative to the base 2) with the sub-bodies 300, and the swing arm 4 drives the pressing piece 5 to swing clockwise (also referred to as "forward"), so that the connection portion 51 is away from the base 2, and applies a force to the shaft cover 1 to move the shaft cover 1 in a direction away from the base 2, thereby achieving "lowering" of the shaft cover 1.
As shown in fig. 11, in the process of switching the two sub-bodies 300 to the unfolded state, the swing arm 4 rotates counterclockwise (i.e., rotates toward the unfolded position relative to the base 2) along with the sub-bodies 300, and the swing arm 4 drives the pressing member 5 to swing counterclockwise (also referred to as "reverse") so that the connecting portion 51 approaches the base 2, at this time, the pressing member 5 no longer applies a force to the shaft cover 1, and the shaft cover 1 moves in a direction approaching the base 2 under the action of the elastic force of the elastic member, thereby realizing "lifting" of the shaft cover 1.
As for other structures in the third embodiment, such as the structure of the swing arm 4, the sub-body 300, the base 2, and the shaft cover 1, and the connection relationship thereof, reference may be made specifically to the arrangement in the second embodiment, and the description thereof will be omitted.
Fig. 12 to 18 show schematic diagrams of a terminal device according to a fourth embodiment of the present application, in which fig. 12 is a schematic diagram of the terminal device according to the fourth embodiment of the present application in a folded state, fig. 13 is a schematic diagram of the terminal device according to the fourth embodiment of the present application in an unfolded state, fig. 14 is a top view of a swing arm 4 of a hinge mechanism according to the fourth embodiment of the present application in an unfolded position, fig. 15 is a side view at an end of a shaft cover of the hinge mechanism according to fig. 14 (parts are not shown to scale in a real product), fig. 16 is a schematic diagram of a structure of the swing arm 4 according to fig. 15 in a folded position, fig. 17 is a B-B sectional view according to fig. 14, and fig. 18 is a C-C sectional view according to fig. 14.
The terminal device in the fourth embodiment is mainly different from the terminal device in the third embodiment in the connection position of the presser 5 and the swing arm 4.
As shown in fig. 13 and 15, one end of the swing arm 4 is provided with a rotation shaft mounting portion 72, the rotation shaft mounting portion 72 is rotatably connected with the base 2 through the rotation shaft 6, the pressing member 5 is connected with the rotation shaft mounting portion 72, and the pressing member 5 and the swing arm 4 are both relatively fixed with the rotation shaft mounting portion 72 in the circumferential direction of the rotation shaft 6.
By arranging the pressing piece 5 at one end of the swing arm 4, the structure between the pressing piece 5 and the swing arm 4 is more compact, and structural interference between the pressing piece 5 and surrounding structures (such as the base 2) when the swing arm 4 rotates is avoided. In addition, the shaft mounting part 72 also plays a role in intermediate transfer, so that the swing arm 4 can be conveniently connected with a plurality of parts such as the shaft 6, the pressing piece 5 and the like.
In some embodiments, as shown in fig. 13 and 15, the presser 5 and the swing arm 4 are located on opposite sides of the shaft mounting portion 72, respectively, in the radial direction of the shaft 6 (such as the X direction shown in fig. 15). That is, the pressing member 5 and the swing arm 4 are located on both sides of the median plane m of the shaft mounting portion 72 in the radial direction of the shaft 6, respectively.
Compared with the pressing member 5 and the swing arm 4 disposed on the same side of the shaft mounting portion 72, the pressing member 5 and the swing arm 4 are disposed on opposite sides of the shaft mounting portion 72, so that the swing arm 4 and the pressing member 5 together form a "lever" to better control the displacement of the connecting portion 51 of the pressing member 5 in the first direction Z, so that the displacement of the connecting portion 51 in the first direction Z is greater, and the lifting effect of the shaft cover 1 is more obvious when the swing arm 4 moves to the extended position.
In some embodiments, as shown in fig. 15, the pressing member 5, the shaft mounting portion 72, and the swing arm 4 are integrally formed. By the design, the number of parts of the rotating shaft mechanism can be reduced, so that the rotating shaft mechanism can be conveniently installed.
Of course, the pressing member 5, the shaft mounting portion 72, and the swing arm 4 may be separately designed according to actual situations, and then assembled together.
In some embodiments, as shown in fig. 15 and 16, along the width direction X of the shaft cover 1, two oppositely disposed cover edges 15 of the shaft cover 1 are respectively bent toward the side close to the base 2, so that the shaft cover 1 encloses the accommodation space 12. The rotation shaft mounting portion 72 has a cylindrical shape, and as shown in fig. 15, when the swing arm 4 is in the extended position, the rotation shaft mounting portion 72 is located at the cover edge 15 and a part thereof protrudes into the accommodation space 12. Through designing the pivot installation department 72 into cylindric to the lid edge 15 is crooked to the side that is close to base 2, like this at swing arm 4 drive pivot installation department 72 pivoted in-process, can avoid pivot installation department 72 and lid edge 15 to take place the structural interference well, thereby make swing arm 4 more smooth and easy in the motion between folding position and the expansion position.
In some embodiments, as shown in fig. 12 to 16, the inner surface 16 of the shaft cover 1 is provided with a first positioning portion 17 and a bearing portion 18, the bearing portion 18 protrudes from the inner surface 16 of the shaft cover 1, the bearing portion 18 is provided with a second positioning portion 181, as shown in fig. 12 and 16, when the swing arm 4 is located at the folded position, the first positioning portion 17 is connected with the connecting portion 51 to position the pressing member 5; as shown in fig. 13 and 15, when the swing arm 4 is in the extended position, the second positioning portion 181 is connected with the connecting portion 51 to position the pressing piece 5. So design, when swing arm 4 is located expansion position and folding position like this, first location portion 17, second location portion 181 just can be with the top casting die 5 location, avoid top casting die 5 to take place to rock to just can avoid swing arm 4 to take place to rock in expansion position and folding position department, and then just can make terminal equipment keep the stable of state when folding state and expansion state.
As shown in fig. 13, the inner surface 16 of the shaft cover 1 refers to a surface of the shaft cover 1 near the base 2.
In some embodiments, as shown in fig. 13 and 15, the bearing portion 18 includes a standing wall 182, and a stop wall 183 disposed at an end of the standing wall 182 away from the inner surface 16 of the shaft cover 1, and the second positioning portion 181 is disposed on the standing wall 182, and a movement space 184 for the pressing member 5 to swing is formed between the stop wall 183 and the inner surface 16 of the shaft cover 1. So designed, the stop wall 183 plays a role in limiting the movement of the pressing member 5, and the stop wall 183 can limit the swing amplitude of the pressing member 5 in the direction approaching the base 2, so that the swing amplitude of the pressing member 5 in the direction approaching the base 2 is prevented from exceeding the movement space 184, and thus, the movement interference of the components (such as the display screen 200 and the like) around the pressing member 5 can be avoided.
Of course, the bearing portion 18 may be configured to include only the standing wall 182, and may be specifically configured according to the actual situation.
As shown in fig. 15, one standing wall 182 may be provided, and two surfaces of the standing wall 182 disposed opposite to each other are respectively provided with a second positioning portion 181, where the two second positioning portions 181 respectively position the pressing member 5 connected to the corresponding swing arm 4. The stopper wall 183 and the standing wall 182 have a T-shaped structure as a whole. As shown in fig. 13, two standing walls 182 may be provided, and the second positioning portions 181 provided on each standing wall 182 may position the pressing member 5 to which the corresponding swing arm 4 is connected. Each of the standing walls 182 is provided with a stopper wall 183, and the stopper wall 183 and the connected standing wall 182 have an inverted L-shaped structure as a whole.
The first positioning portion 17 and the second positioning portion 181 are not unique in structure, and in some embodiments, as shown in fig. 15 and 16, the first positioning portion 17 and the second positioning portion 181 are positioning grooves into which the connection portion 51 extends, and the positioning grooves are arcuate in a section perpendicular to the rotating shaft 6, that is, the groove walls of the positioning grooves are arcuate in a section perpendicular to the rotating shaft 6.
By designing the first positioning portion 17 and the second positioning portion 181 into positioning grooves, the structure of the first positioning portion 17 and the second positioning portion 181 is simpler and easy to manufacture, thereby being beneficial to reducing the design and manufacturing cost of the rotating shaft mechanism 100. Meanwhile, the section of the positioning groove is designed to be arc-shaped, so that when the swing arm 4 is switched between the folded position and the unfolded position, the groove wall of the positioning groove plays a guiding role, the pressing piece 5 is conveniently moved out of the positioning groove, and the resistance of the terminal equipment in the switching between the folded state and the unfolded state is reduced.
In some embodiments, as shown in fig. 15 and 16, the connection portion 51 of the pressing member 5 has a curved surface that can be fitted with a positioning groove. By such design, when the swing arm 4 is switched between the folded position and the unfolded position, the connecting part 51 with the curved surface is more easily moved out of the positioning groove, so that the resistance of the terminal equipment is further reduced when the terminal equipment is switched between the folded state and the unfolded state.
The curved surface can be a cambered surface or a paraboloid, and is particularly matched with the section shape of the positioning groove.
In some embodiments, as shown in fig. 15 and 16, the positioning groove is a bar-shaped groove extending along the axial direction (Y direction shown in the drawing) of the rotating shaft 6, the pressing member 5 is a pressing rib, and an end of the pressing rib away from the swing arm 4 is a connecting portion 51. By the design, when the propping piece 5 stretches into the positioning groove, the contact surface between the propping piece 5 and the groove wall of the positioning groove is larger, so that the positioning effect of the positioning groove on the propping piece 5 is better.
In addition, the thickness of the jacking rib is usually thinner (namely a thin-wall structure), so that the jacking rib has certain elasticity, and in the process of stretching into or removing from the positioning groove, certain elastic deformation can be generated on the jacking rib to avoid the blocking of the edge of the positioning groove, so that the process of stretching into or removing from the positioning groove by the jacking rib is easier.
The positioning groove may be a spherical groove (the groove wall of the positioning groove is a part of a spherical surface), and correspondingly, the pressing member 5 is a stop lever, and the curved surface at the connecting portion 51 of the stop lever is a spherical surface.
The first positioning portion 17 and the second positioning portion 181 may be magnetic absorbing members, such as magnets, and the connecting portion 51 of the pressing member 5 may be made of magnetic materials, such as iron, so that the connecting portion 51 of the pressing member 5 may be magnetically absorbed by the first positioning portion 17 and the second positioning portion 181 when approaching the first positioning portion 17 and the second positioning portion 181, thereby positioning the pressing member 5.
In some embodiments, as shown in fig. 14, the number of the swing arms 4 is two, each of the two pairs of swing arms 4 is connected with a pressing member 5, the two pairs of swing arms 4 are respectively disposed at two ends of the shaft cover 1 along the length direction Y thereof, and each pair of swing arms 4 is respectively rotatably connected to two opposite side edges of the base 2 along the width direction X of the shaft cover 1. By means of the design, when the swing arm 4 moves towards the folding position, the shaft cover 1 can be guaranteed to be more uniform in extrusion force of the pressing piece 5, and accordingly descending movement of the shaft cover 1 is stable.
In some embodiments, as shown in fig. 14 and 18, along the length direction Y of the shaft cover 1, the bearing portion 18 and the pressing piece 5 are both located at the end of the base 2, and the orthographic projections of the bearing portion 18, the pressing piece 5 on the shaft cover 1 are both located outside the orthographic projection of the base 2 on the shaft cover 1. By such design, the carrying part 18 is arranged on the base 2 without arranging an avoidance port, thereby facilitating the arrangement of the carrying part 18. At the same time, interference of the pressing member 5 with the base 2 during the swinging is avoided.
In some embodiments, as shown in fig. 14, along the length direction Y of the shaft cover 1, the swing arm 4 is located at the end of the base 2, and the front projection of the swing arm 4 on the shaft cover 1 is located outside the front projection of the base 2 on the shaft cover 1. Thus, the swing arm 4 can be prevented from interfering with the base 2 in the rotation process, and the arrangement of the swing arm 4 is facilitated.
As shown in fig. 14, one end of the rotating shaft 6 is inserted into an end of the base 2 to form a cantilever structure, and the swing arm 4 is connected to a portion of the rotating shaft 6 exposed outside the base 2.
In some embodiments, as shown in fig. 14 and 15, the rotating shaft 6 includes a flat shaft section 61 and a cylindrical shaft section 62 connected to the flat shaft section 61, and the rotating shaft mounting portion 72 is provided with a stepped hole 721 matching with the flat shaft section 61 and the cylindrical shaft section 62, so that the rotating shaft 6 is relatively fixed to the rotating shaft mounting portion 72 in the circumferential direction thereof.
The flat shaft section 61 has at least one plane on its circumferential surface, for example, as shown in fig. 15, and two planes disposed opposite to each other are provided on the circumferential surface of the flat shaft section 61.
In some embodiments, as shown in fig. 13, 14 and 18, when the swing arm 4 is in the extended position, the bearing portion 18 is not higher than a side surface of the base 2 away from the shaft cover 1, that is: the top of the bearing 18 is flush with the side surface of the base 2 remote from the shaft cover 1, or the top of the bearing 18 is lower than the side surface of the base 2 remote from the shaft cover 1. By such design, when the terminal device is in the unfolded state, the top of the bearing part 18 can be prevented from being propped against the display screen 200, so that the display screen 200 is damaged.
Wherein the top of the carrier 18 is the end of the carrier 18 remote from the inner surface 16 of the shaft cover 1. The top of the bearing 18 below the side surface of the base 2 remote from the shaft cover 1 means in particular: the distance from the top of the carrier 18 to the inner surface 16 of the shaft cover 1 is smaller than the distance from the side surface of the base 2 remote from the shaft cover 1 to the inner surface 16 of the shaft cover 1.
In some embodiments, as shown in fig. 13 and 17, a guide post 191 is provided on the shaft cover 1, the guide post 191 extends along the first direction Z, and a guide hole 21 is provided on the base 2, and the guide post 191 is slidably engaged with the guide hole 21, so that the shaft cover 1 is slidably connected to the base 2 along the first direction Z. So designed, the sliding structure between the shaft cover 1 and the base 2 is simpler, and the occupied space is smaller.
As shown in fig. 17, the base 2 includes a lower seat 23, and an upper seat 22 located on a side of the lower seat 23 away from the shaft cover 1, wherein the upper seat 22 is detachably connected (e.g., fastened by a screw or the like) to the lower seat 23, and the guide hole 21 is provided on the lower seat 23.
Of course, the above-mentioned guide posts 191 and the guide holes 21 may be disposed at opposite positions, that is, the guide posts 191 are disposed on the base 2, and the guide holes 21 are disposed on the shaft cover 1, so that the sliding structure between the shaft cover 1 and the base 2 is simpler and occupies less space.
In some embodiments, as shown in fig. 14, the guide posts 191 and the guide holes 21 are correspondingly arranged in a plurality of pairs, such as three pairs, along the length direction Y of the shaft cover 1. By the design, when the shaft cover 1 moves up and down, the stress balance of the shaft cover 1 in the length direction Y can be ensured, so that the lifting movement and the lowering movement of the shaft cover 1 are more stable.
In some embodiments, as shown in fig. 6, the elastic member 3 is a spring, which is sleeved on the guide post 191, and has one end connected to the shaft cover 1 and the other end connected to the base 2. Through locating the elastic component 3 cover on the guide post 191, the guide post 191 plays spacing effect to the elastic component 3 like this, can make the position of elastic component 3 more stable, is difficult for taking place the skew at the position of elastic component 3 of the in-process of the rising motion of lid 1 and decline motion.
Fig. 19 to 23 show schematic diagrams of a terminal device according to a fifth embodiment of the present application, in which fig. 19 is a schematic diagram of the terminal device according to the fifth embodiment of the present application in a folded state, fig. 20 is a schematic diagram of the terminal device according to the fifth embodiment of the present application in an unfolded state, fig. 21 is a top view of a swing arm 4 of a hinge mechanism according to the fifth embodiment of the present application in an unfolded position, fig. 22 is a sectional view of the hinge mechanism according to fig. 21 at D-D, and fig. 23 is a sectional view of the hinge mechanism according to fig. 21 at E-E.
The terminal device in the fifth embodiment is mainly different from the terminal device in the fourth embodiment in the structure of the swing arm 4.
As shown in fig. 19, 20 and 21, the swing arm 4 includes a first swing arm 41 and a second swing arm 42, where the first swing arm 41 and the second swing arm 42 are rotatably connected to the base 2, the first swing arm 41 is fixedly connected to the sub-body 300, and the first swing arm 41 is further slidably connected to the second swing arm 42 (i.e., there is a sliding constraint between the first swing arm 41 and the second swing arm 42), so that the first swing arm 41 can drive the second swing arm 42 to move between an extended position and a folded position, and the pressing member 5 is connected to the second swing arm 42.
Taking the first swing arm 41, the second swing arm 42, and the sub-body 300 located on the left side in fig. 19 and 20 as an example, the process of folding and unfolding the terminal device in the embodiment of the present application is described as follows:
as shown in fig. 19, in the process of switching the two sub-bodies 300 to the folded state, the first swing arm 41 swings clockwise with the sub-bodies 300, and by virtue of the sliding constraint between the first swing arm 41 and the second swing arm 42, the first swing arm 41 drives the second swing arm 42 to swing clockwise while swinging, and then drives the pressing member 5 to swing clockwise (also referred to as "forward"), so that the connecting portion 51 is far away from the base 2, and a force is applied to the shaft cover 1, so that the shaft cover 1 moves in a direction far away from the base 2, thereby realizing "lowering" of the shaft cover 1.
As shown in fig. 20, in the process of switching the two sub-bodies 300 to the unfolded state, the first swing arm 41 swings anticlockwise along with the sub-bodies 300, and by virtue of the sliding constraint between the first swing arm 41 and the second swing arm 42, the first swing arm 41 drives the second swing arm 42 to swing anticlockwise while swinging, and then drives the pressing member 5 to swing anticlockwise (also referred to as "reverse"), so that the connecting portion 51 approaches the base 2, at this time, the pressing member 5 no longer applies an acting force to the shaft cover 1, and the shaft cover 1 moves in a direction approaching the base under the action of the elastic force of the elastic member, thereby realizing "lifting" of the shaft cover 1.
By arranging the swing arm 4 as the first swing arm 41 and the second swing arm 42, the first swing arm 41 is fixedly connected with the sub-body 300, and the first swing arm 41 and the second swing arm 42 are in sliding connection, so that the degree of freedom of a mechanism formed by the sub-body 300, the first swing arm 41, the second swing arm 42 and the base 2 is 1, and the two sub-bodies 300 can be ensured to be unfolded and folded smoothly.
