The folding mechanism and the electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1 to 8, an embodiment of the present application discloses a hinge mechanism, which can be applied to an electronic device to enable the electronic device to have a folding capability. Electronic devices typically include a display screen and a screen support portion that provides a mounting base for the display screen and may provide support for the display screen. The number of the screen supporting parts is plural, and specifically may be two, three or more, for convenience of understanding, the following description and the electronic device including two screen supporting parts are taken as examples, and the specific structure, the working state and the like of the electronic device are described, as for the embodiment where the number of the screen supporting parts is more, those skilled in the art can correspondingly expand according to the technical idea of the present application, and the detailed description is omitted here.
The two screen supporting parts are connected through the hinge mechanism, and under the action of the hinge mechanism, the two screen supporting parts have relative movement capacity, so that the electronic equipment can be switched between a folded state and an unfolded state.
Under the condition that the electronic equipment is in a folded state, the two screen supporting parts are stacked and oppositely arranged, and the display screen is positioned between the two screen supporting parts. Of course, the two screen supporting portions may be parallel to each other, or an acute angle with a relatively small value may exist between the two screen supporting portions.
When the electronic device is in the unfolded state, the display surface of the display screen is a plane, and the two screen supporting parts are in a substantially coplanar state. Of course, considering the influence of factors such as the processing precision and the property of the display screen itself, the display surface of the display screen in the unfolded state may not be an absolute plane structure, and some positions of the display surface in the display screen may have some bending deformation, and in this case, the display screen (or the electronic device) may also be considered to be in the unfolded state.
As described above, during the use of the electronic device, the display screen may deform along with the relative movement of the screen support portion, and then, at least a portion of the display screen is of a flexible structure. Specifically, the display screen may include a first display portion, a second display portion, and a third display portion, and the first display portion and the second display portion are connected through the third display portion, so that the first display portion, the second display portion, and the third display portion are connected as a whole. Optionally, the first display part and the second display part are hard screens to prolong the service lives of the first display part and the second display part, the third display part is a flexible screen, the position of the third display part corresponds to the position of the hinge mechanism, and the third display part is guaranteed not to obstruct normal bending and unfolding actions of the hinge mechanism. In another embodiment of the application, the display screen can be wholly flexible, and this can also guarantee that the display screen possesses the ability of warping along with the action of the hinge mechanism, and can promote the uniformity of display screen, and then promote the display effect of display screen.
As shown in fig. 1 to 8, a hinge mechanism disclosed in an embodiment of the present application includes a base 100, a first rotating portion, a second rotating portion 230, a first connecting portion 210, a second connecting portion 220, a first synchronizing swing arm 410, and a second synchronizing swing arm 420.
The first connecting portion 210 and the second connecting portion 220 are both used for being fixedly connected with a screen supporting portion of the electronic device, so that adjacent screen supporting portions in the electronic device can form a connection relationship with the hinge mechanism, and further the adjacent screen supporting portions can move relatively by using the hinge mechanism. Specifically, each of the first and second connection parts 210 and 220 may be fixedly connected to the corresponding screen support part using screws or the like. As for the actual structure, size and the like of the first connecting portion 210 and the second connecting portion 220, they may be determined according to the actual shape and size of other components such as a screen supporting portion in the electronic device, and are not limited herein.
Optionally, the number of the first connecting portion 210 and the second connecting portion 220 is one, and the first connecting portion and the second connecting portion are respectively located on two opposite sides of the whole hinge mechanism to be respectively connected with the corresponding screen supporting portions. In another embodiment of the present application, optionally, as shown in fig. 1, the number of the first connection portions 210 and the number of the second connection portions 220 may be multiple, the multiple first connection portions 210 are all distributed on one side of the whole hinge mechanism, and the multiple first connection portions 210 are distributed along one direction with a larger size in the whole hinge mechanism, where the direction may be specifically a length direction of the hinge mechanism, and also be a direction in which a rotation axis of the first rotation portion (or the first synchronization swing arm 410) in the hinge mechanism is located, and the direction is specifically a direction a in fig. 1. Correspondingly, the plurality of second connecting portions 220 are uniformly distributed on the other side of the whole hinge mechanism, and the plurality of second connecting portions 220 are distributed along the length direction of the whole hinge mechanism. The plurality of first connecting portions 210 and the plurality of second connecting portions 220 are all fixedly connected with corresponding screen supporting portions in the electronic device, so that the connection reliability and the stress stability between the adjacent screen supporting portions are improved.
The base 100 is a fundamental part of the overall hinge mechanism, and other structures in the hinge mechanism may be mounted directly or indirectly to the base 100 to form a connected relationship with the base 100. In addition, many components or structures of the hinge mechanism are symmetrically disposed, such as a plurality of first rotating portions, and the plurality of first rotating portions are disposed on the base 100. After eliminating the influence of the factors such as the position, the plurality of first rotating portions include two first rotating portions symmetrically arranged on the structure, one of the two first rotating portions is used for being matched with the first connecting portion 210, and the other one is used for being matched with the second connecting portion 220.
Similarly, the number of the second rotating portions 230 is also plural, and the plural second rotating portions 230 are matched with the plural first rotating portions in a one-to-one correspondence. The second rotating portions 230 include two second rotating portions 230, which are in one-to-one correspondence with the two first rotating portions having the above-mentioned symmetrical structure, and form a rotating connection relationship, and one of the two second rotating portions 230 is connected to the first connecting portion 210, and the other is connected to the second connecting portion 220.
As described above, the first rotating portion and the second rotating portion 230 are engaged with each other with a rotation engagement relationship formed therebetween. Specifically, both of them can be a structural combination in which the rotation axes such as the arc-shaped structural member are located outside the two, so that the sizes of the base 100 and the whole hinge mechanism can be reduced, and the complexity of the base 100 can be reduced. Under the condition that first rotation portion and second rotation portion 230 adopt aforementioned structure, because first rotation portion sets up in base 100 to can utilize base 100 to provide the limiting displacement in the direction of the aforementioned axis of rotation of perpendicular to for second rotation portion 230, guarantee that the rotation fit relation between second rotation portion 230 and the first rotation portion is comparatively stable. The direction perpendicular to the rotation axis may be a left-right direction of the paper sheet in fig. 3.
In another embodiment of the present application, the first rotating portion may be provided with a sinking groove, and the second rotating portion 230 is slidably disposed in the sinking groove, so that the first rotating portion and the second rotating portion 230 form a rotating fit relationship. Also, a guide rail may be provided on an inner wall of the sinking groove, and the extending direction of the guide rail may be the same as the moving track of the second rotating part 230 with respect to the base 100. Meanwhile, by providing the guide groove on the second rotating portion 230, the first rotating portion and the second rotating portion 230 can be ensured to stably maintain a relative rotation state by using a sliding fit of the guide rail and the guide groove. Accordingly, under the action of the guide rail and the guide groove, the limit fit relationship of the first rotating portion and the second rotating portion 230 in the direction of the rotation axis of the first rotating portion can be further stabilized.
Further, the guide rail may be provided at a side wall of the sinking groove of the first rotating part, i.e., a surface perpendicular to the rotation axis of the first rotating part in the sinking groove of the first rotating part. Based on this, the guide rail and the guide groove can also form a limit fit relationship in a direction perpendicular to the rotation axis of the first rotating portion, which can also ensure that the rotation fit relationship between the first rotating portion and the second rotating portion 230 has high stability.
As described above, at least one of the second rotating portions 230 is fixedly connected to the first connecting portion 210, and forms an interlocking relationship; at least one other of the second rotating portions 230 is fixedly connected with the second connecting portion 220, and the two form an interlocking relationship. Meanwhile, the first connecting portion 210 and the second connecting portion 220 are both used for being connected with a screen supporting portion of the electronic device, and then the first rotating portion and the second rotating portion 230 which are in running fit are utilized, so that the base 100 can connect two adjacent screen supporting portions together, and when the first connecting portion 210 and the second connecting portion 220 move relatively, the corresponding second rotating portion 230 can be driven to rotate relatively to the first rotating portion.
In order to enable the first connection portion 210 and the second connection portion 220 to synchronously rotate with respect to the base 100, optionally, as shown in fig. 2, the hinge mechanism disclosed in the embodiment of the present application may further include a synchronization assembly, where the synchronization assembly includes a first synchronization swing arm 410 and a second synchronization swing arm 420, the first synchronization swing arm 410 is connected to the first connection portion 210, and the two are in linkage relationship, so that the first connection portion 210 can drive the first synchronization swing arm 410 to rotate with respect to the base 100; the second synchronous swing arm 420 is connected to the second connecting portion 220, and the second synchronous swing arm 420 and the second connecting portion 220 form a linkage relationship, so that the second connecting portion 220 can drive the second synchronous swing arm 420 to rotate relative to the base 100, and further can drive the first synchronous swing arm 410 and the second synchronous swing arm 420 to rotate relative to each other when the first connecting portion 210 and the second connecting portion 220 move relative to each other. Furthermore, the first and second synchronous swing arms 410 and 420 are in transmission connection, and when a force is applied to only one of the first and second connection portions 210 and 220, the first and second connection portions 210 and 220 can synchronously rotate relative to the base 100 under the transmission action of the first and second synchronous swing arms 410 and 420.
Specifically, the first synchronization swing arm 410 and the second synchronization swing arm 420 may be in a transmission connection via a meshing gear, or may be in a transmission connection via another transmission. In addition, in order to ensure that the first synchronization swing arm 410 and the second synchronization swing arm 420 can form a stable transmission matching relationship, as shown in fig. 4, the first synchronization swing arm 410 and the second synchronization swing arm 420 can both form a rotation matching relationship with the base 100 through the connecting rod 800, and further, when the first synchronization swing arm 410 rotates relative to the base 100, the first synchronization swing arm 410 can be ensured to stably drive the second synchronization swing arm 420 to rotate relative to the base 100. Specifically, the first and second synchronizing swing arms 410 and 420 may each be in a stable rotation-fitting relationship with the base 100 by means of the link 800, and the two links 800 are spaced apart from each other in a direction perpendicular to the rotation axis. In the circumferential direction of the rotation axis of the first rotating portion, the first and second synchronization swing arms 410 and 420 may be in a rotation fit relationship with the corresponding connecting rods 800, or each connecting rod 800 may also be in a rotation fit relationship with the base 100.
As described above, the first and second synchronization swing arms 410 and 420 are respectively connected to the first and second connection portions 210 and 220, and since the rotation axes of the first and second synchronization swing arms 410 and the corresponding first rotation portions are different, the first synchronization swing arm 410 and the first connection portion 210 can also move relatively when the first synchronization swing arm 410 rotates along with the first connection portion 210 along the axis of the first rotation portion. Based on this, the first synchronization swing arm 410 and the first connection portion 210 can form a sliding fit relationship, for example, the first synchronization swing arm 410 and the first connection portion 210 can form a sliding connection relationship through a sliding sleeve and a pin shaft which are in sliding fit, the sliding sleeve is provided with a track, and the pin shaft is inserted into the sliding sleeve and moves relative to the sliding sleeve along the track.
In another embodiment of the present application, taking the first synchronization swing arm 410 as an example, as shown in fig. 4 to 8, the first synchronization swing arm 410 may include a synchronization arm 411 and a sliding base 412, and the first connection portion 210 is provided with a sliding slot 211, wherein the sliding base 412 is in surface contact with and in sliding fit with the sliding slot 211 of the first connection portion 210, so that a fit area between the sliding base 412 and the first connection portion 210 is relatively larger, and stability and reliability of fit between the first synchronization swing arm 410 and the first connection portion 210 are improved; meanwhile, the synchronizing arm 411 of the first synchronizing swing arm 410 is rotatably connected with the base 100 through the connecting rod 800, and accordingly, the first synchronizing swing arm 410 is in transmission connection with the second synchronizing swing arm through the synchronizing arm 411 thereof. Of course, the specific structure and connection relationship of the second synchronization swing arm 420 may be correspondingly set with reference to the first synchronization swing arm 410.
The hinge mechanism of the structure has at least two states, namely a first state and a second state when working, wherein the first state corresponds to the unfolding state of the electronic equipment, and the second state corresponds to the folding state of the electronic equipment.
When the hinge mechanism is in the first state, the first connecting portion 210 is located on one side of the base 100, and the second connecting portion 220 is located on the other side of the base 100, so that the hinge mechanism is in an unfolded state as a whole, and the screen supporting portions connected by the hinge mechanism are ensured to be in a substantially coplanar state while providing a supporting effect for the middle portion of the display screen, and provide a supporting effect for the two side portions of the display screen respectively.
In the case where the hinge mechanism is in the second state, the first connecting portion 210 and the second connecting portion 220 are both located on the side of the base 100 toward the self screen support side. Accordingly, since the first connecting portion 210 and the second connecting portion 220 connected to the screen supporting portion are both located at the screen supporting side of the base 100, that is, the display screen and the screen supporting portion are both located at the same side of the base 100, the display screen is integrally wrapped by the screen supporting portion and the hinge mechanism, and the "fold-in" electronic device is formed.
The embodiment of the application discloses a hinge mechanism, wherein a first connecting part 210 and a second connecting part 220 of the hinge mechanism can be fixedly connected with a screen supporting part of an electronic device, so that adjacent screen supporting parts can form a connection relation through the hinge mechanism. Moreover, the first connecting portion 210 can form a rotating fit relationship with at least one first rotating portion on the base 100 through at least one second rotating portion 230, and the second connecting portion 220 can form a rotating fit relationship with at least another first rotating portion on the base 100 through at least another second rotating portion 230, so that when the adjacent screen supporting portions move relatively, the first connecting portion 210 and the second connecting portion 220 can also move relatively, and the electronic device has the capability of unfolding and folding.
Simultaneously, because the electronic equipment who utilizes above-mentioned hinge mechanism to form is interior folding type electronic equipment, and then under this electronic equipment is in the condition of fold condition for screen supporting part and hinge mechanism can provide the guard action for the display screen, prevent that the display screen from taking place friction or collision with external object, and this life that can promote the display screen among the electronic equipment.
In addition, in the above hinge mechanism, the first synchronous swing arm 410 includes the synchronous arm 411 and the sliding base 412 that are connected to each other, the sliding slot 211 is formed on the first connection portion 210, and the sliding base 412 and the sliding slot 211 are in surface contact and in sliding fit, so that the contact area between the first synchronous swing arm 410 and the first connection portion 210 is relatively large, and further the stress reliability between the first synchronous swing arm 410 and the first connection portion 210 is relatively high, and the pressure intensity between the first synchronous swing arm 410 and the first connection portion 210 can be reduced, the probability of damage when the first synchronous swing arm 410 and the first connection portion 210 interact with each other is reduced, the service life of the first synchronous swing arm 410 and the usability of the whole hinge are improved.
As mentioned above, the first synchronous swing arm 410 is rotatably mounted on the base through the first connecting rod, and since the rotation axis of the first rotating portion is not located on the base, when the first synchronous swing arm 410 connected to the first connecting portion 210 rotates relative to the base 100 along with the first connecting portion 210, a relative motion in a direction perpendicular to the rotation axis is generated between the first synchronous swing arm 410 and the first connecting portion 210, and auxiliary components of the relative motion are the sliding base 412 and the sliding slot 211. Further, the sliding base 412 and the sliding groove 211 are relatively moved in a specific case where a part of the sliding base 412 is reciprocally switched between two states of being located inside the sliding groove 211 and being located outside the sliding groove 211.
Obviously, during the process of sliding a part of the sliding seat 412 out of the sliding groove 211 (i.e. the process of switching the hinge mechanism from the first state to the second state), the contact area between the sliding seat 412 and the sliding groove 211 is continuously reduced, which causes the contact area between the first synchronous swing arm 410 and the first connecting portion 210 to be reduced, thereby adversely affecting the stability of the fit between the two.
For the above reasons, further, the hinge mechanism disclosed in the embodiments of the present application may further include a sliding assembly, as shown in fig. 4 to 8, the sliding assembly includes a sliding sleeve 710, the sliding sleeve 710 is in surface contact with and slidably engaged with the sliding groove 211, the sliding sleeve 710 is provided with a sliding way 711, and the sliding base 412 is in surface contact with and slidably engaged with the sliding way 711. In brief, in the present embodiment, a sliding sleeve 710 is further added to the hinge mechanism, and the sliding sleeve 710 is used as a bridging connection to connect between the sliding base 412 and the sliding slot 211, and both the sliding base 412 and the sliding slot 211 and the sliding sleeve 710 are in a surface contact and sliding fit relationship.
Of course, when the above-described slide sleeve 710 is included in the hinge mechanism, in order to ensure that the sum of the contact areas between the slide base 412 and the slide groove 211 can be larger than the contact area between the slide base 412 and the slide groove 211 when the slide base 412 is directly mounted into the slide groove 211, further, in the case where the hinge mechanism is in the second state, a part of the slide sleeve 710 is located in the slide groove 211, a part of the slide base 412 is located in the slide passage 711, and the size of the portion where the slide groove 211 overlaps with the slide base 710 is larger than the size of the portion where the slide groove 211 overlaps with the slide base 412 in the sliding direction of the slide sleeve 710 and the slide groove 211.
In general, when the hinge mechanism is in the second state, it is necessary to ensure that a part of the sliding base 412 is still located in the sliding channel 711 and a part of the sliding sleeve 710 is located in the sliding channel 211, so as to ensure that the sliding base 412 can still form a connection relationship with the first connection portion 210 through the sliding sleeve 710. Further, the sum of the size of the portion where the slide base 412 and the slide sleeve 710 overlap in the aforementioned direction (i.e., the portion where the slide base and the slide groove 710 are in surface contact with each other) and the size of the portion where the slide sleeve 710 and the slide groove 211 overlap in the aforementioned sliding direction may be regarded as the size of the portion where the slide base 412 and the slide groove 211 indirectly form surface engagement with each other.
Furthermore, in the direction in which the sliding sleeve 710 and the sliding groove 211 slide relatively, compared with the technical solution in which the sliding base 412 is directly installed into the sliding groove 211, by adopting the technical solution provided by this embodiment, the area of the portion (directly or indirectly) in surface contact and engagement between the sliding base 412 and the sliding groove 211 can be increased, so as to further increase the engagement stability between the first synchronization swing arm 410 and the first connection portion 210.
Of course, in order to prevent the slide base 412 from moving freely relative to the slide sleeve 710 during the process of switching the hinge mechanism from the first state to the second state, and thus causing the two to separate, a specific embodiment may be, a blocking rod and other structures are arranged at one end of the sliding seat 412, which is far away from the base, the size of the blocking rod and other structures in the direction of the rotating axis is larger than that of the sliding sleeve 710 in the direction of the rotating axis, meanwhile, by disposing the blocking rod and the sliding base 412 at an interval in the sliding direction, that is, while ensuring that the sliding base 412 can move relative to the sliding sleeve 710, a limiting condition is set for the relative movement of the sliding base and the sliding sleeve 710 in the aforementioned sliding direction, so that when the blocking rod blocks the end face of the sliding sleeve 710 that faces away from the base 100, the sliding sleeve 710 and the sliding base 412 are fixed relatively, and then the first synchronous swing arm 410 drives the sliding sleeve 710 to move along the sliding direction relative to the first connecting portion 210.
Of course, in order to prevent the excessive amount of the relative movement between the sliding sleeve 710 and the first connecting portion 210, the dimensions of the sliding sleeve 710 and the first connecting portion 210 in the aforementioned sliding direction can be designed correspondingly based on the parameters such as the relative displacement amount between the first synchronization swing arm 410 and the first connecting portion 210 and the maximum displacement amount between the first synchronization swing arm 410 and the sliding sleeve 710 when the hinge mechanism is switched between the first state and the second state, so as to prevent the sliding sleeve 710 and the first connecting portion 210 from being separated. Alternatively, the relative displacement between the sliding sleeve 710 and the first connecting portion 210 in the sliding direction may also be limited by providing a corresponding limiting structure, which is not limited herein.
In order to prevent the sliding base 412 and the sliding sleeve 710 from separating during the relative movement, as shown in fig. 8, a specific embodiment is that a strip-shaped hole 412a is formed in the sliding base 412, the extending direction of the strip-shaped hole 412a is parallel to the sliding direction, meanwhile, the sliding sleeve 710 is provided with a positioning hole 713, the hinge mechanism further includes a positioning pin 720, the positioning pin is fixed in the positioning hole 713, and extends into the strip-shaped hole 412a, so that the positioning pin 720 can move in the strip-shaped hole 412a relative to the positioning hole 713, and the positioning pin 720 and the strip-shaped hole 412a can form a movable fit relation in the sliding direction. Accordingly, when the positioning pin 720 contacts one of the two inner sidewalls of the strip-shaped hole 412a along the sliding direction, the sliding base 412 and the sliding sleeve 710 can be limited, so as to prevent the sliding base 412 and the sliding sleeve 710 from being separated due to an excessive relative displacement therebetween.
Specifically, the positioning pin 720 may include a nail cap and a nail rod that are fixedly connected, the nail rod is configured to penetrate through the positioning hole 713 and the strip-shaped hole 412a, and the nail cap is limited at an end surface of the sliding sleeve 710 that is away from the sliding seat 412; one end of the nail rod, which deviates from the nail cap, can be provided with a through hole, and the sliding sleeve 710 and the sliding seat 412 can be positioned by the positioning pin 720 by utilizing a clamping piece penetrating through the through hole. In another embodiment of the present application, the positioning pin 720 and the positioning hole 713 may be screwed to form a fixed connection relationship.
As described above, the sliding sleeve 710 is installed in the sliding groove 211 of the first connecting portion 210, and in order to facilitate the installation work of the positioning pin 720, optionally, an avoiding region is provided on the first connecting portion 210 and faces the positioning hole 713 of the sliding sleeve 710, so that the positioning pin 720 can be installed to the positioning hole 713 from the avoiding region. The specific shape, size and other parameters of the avoidance area can be determined according to actual requirements, and are not limited herein.
As described above, the first and second synchronizing swing arms 410 and 420 may be in a transmission connection relationship through the engaging teeth, that is, the first and second synchronizing swing arms 410 and 420 are both provided with the engaging teeth, and they may be directly combined through the respective engaging teeth to form a transmission matching relationship.
In order to reduce the pitch circle diameters of the meshing teeth of the first and second synchronizing swing arms 410 and 420, in another embodiment of the present application, the hinge mechanism may further include a first gear and a second gear that mesh with each other, and then the first gear and the second gear may be utilized to provide a bridging effect for the transmission connection relationship between the first synchronizing swing arm 410 and the second synchronizing swing arm 420, so as to reduce the pitch circle diameters of the meshing teeth of the first synchronizing swing arm 410 and the second synchronizing swing arm 420, and further reduce the size of the corresponding partial structures on the first synchronizing swing arm 410 and the second synchronizing swing arm 420, and reduce the size of the hinge mechanism in a direction perpendicular to the rotation axis of the first rotating part.
Of course, in order to ensure the motion stability of the first and second gears, a gear shaft may be provided for each of the first and second gears, and the gear shaft may be installed on the gear hole of the base 100 to provide a supporting function for the first and second gears. Accordingly, a rotational fit relationship is required to be formed between one of the first gear and the base 100 and the gear shaft, and a rotational fit relationship is also required to be formed between the gear shaft corresponding to the second gear and the base 100 or the second gear.
In the present embodiment, the outer circumferential walls of the first and second synchronizing swing arms 410 and 420 may be processed to form the engaging teeth. In another embodiment of the present application, a mating gear may be further installed on the connecting rod 800, and the mating gear and the first synchronous swing arm 410 are relatively fixed in the circumferential direction of the rotation axis, so as to drive the mating gear to rotate in the process of rotating the first synchronous swing arm 410. The first synchronous swing arm 410 can also be in transmission connection with the first gear through the matching gear being in transmission connection with the first gear.
Under the condition of adopting the technical scheme, the gear standard component can be directly utilized as the meshing teeth of the first synchronous swinging arm 410, so that the meshing teeth do not need to be additionally processed on the outer peripheral wall of the first synchronous swinging arm 410, and the integral processing difficulty of the hinge mechanism can be greatly reduced. Similarly, the second synchronous swing arm 420 may also be provided with a mating gear, and the mating gear is meshed with the second gear, so that the second synchronous swing arm 420 may also be in transmission connection with the second gear through the mating gear.
In the above embodiment, taking the first synchronous swing arm 410 and the corresponding mating gear as an example, the two can form a relative fixed relationship in the circumferential direction of the rotation axis by welding. Considering the post-maintenance of the hinge mechanism, the first synchronization swing arm 410 and the corresponding link 800 may be relatively fixed in the circumferential direction of the rotation axis of the first rotation portion, and the mating gear and the link 800 may also be relatively fixed in the aforementioned direction. In this case, it is ensured that the first synchronous swing arm 410 can be brought into a relatively fixed relationship with the mating gear in the aforementioned circumferential direction by the connecting rod 800. Similarly, the second synchronous swing arm 420 and the corresponding mating gear can also form a relatively fixed relationship in the circumferential direction by using the above technical solution.
In the above embodiment, the link 800 and the first synchronization swing arm 410 can be engaged with each other through a key connection, so that the link 800 rotates with the first synchronization swing arm 410 relative to the base 100. In the process of assembling the connecting rod 800 and the base 100, a limiting structure may be disposed on the base 100, and the first gear and the second gear may be limited in the limiting structure, so that the first gear and the second gear form a relatively stable fixed relationship with the base 100 in the direction of the rotation axis.
Further, base 100 can be equipped with limit structure, and limit structure specifically can include the open slot to, can also correspond in the opening one side of open slot and set up the baffle, and then, at the in-process of equipment first gear, second gear and base 100, can make first gear and second gear all install in the open slot, and make open slot and baffle provide limiting displacement for first gear and second gear in the lump. Meanwhile, a gear hole can be formed in the baffle in a machining mode, one end of the gear shaft penetrates through the first gear (or the second gear) through the gear hole and is finally inserted into the side wall of the open groove, and a supporting effect is provided for the first gear.
In another embodiment of the present application, the first gear and the gear shaft are an integrated structure, in which case, the connection reliability between the first gear and the gear shaft can be improved, and the stability of the linkage process between the first gear and the first synchronous swing arm 410 can be ensured. In this embodiment, the first gear and the gear shaft can be inserted between the open groove and the baffle plate by designing the size of the open groove, so that the first gear is stably rotatably mounted on the base 100.
In order to prevent the first synchronization swing arm 410 and the connecting rod 800 from moving relatively in the direction of the rotation axis, so as to adversely affect the transmission connection relationship between the first synchronization swing arm 410 and the first gear (or the second synchronization swing arm 420), optionally, the hinge mechanism disclosed in the embodiment of the present application may further include a first elastic member 500, where in the direction of the rotation axis of the first rotation portion, the first elastic member 500 is connected between the base 100 and the first synchronization swing arm 410, so that the first synchronization swing arm 410 and the base 100 form a press fit relationship in the direction of the rotation axis of the first rotation portion by using the first elastic member 500, thereby restricting the autonomous rotation of the first synchronization swing arm 410, and making the hinge mechanism have a damping feeling. Meanwhile, the first synchronization swing arm 410 is prevented from moving relative to the base 100 in the direction of the aforementioned rotation axis with respect to the base 100 by the first elastic member 500.
Specifically, the first elastic member 500 and the first synchronization swing arm 410 may be directly connected to each other, such as abutting connection or fixed connection, or indirectly connected to each other through another structural member, so that the elastic force of the first elastic member 500 can act on the first synchronization swing arm 410. By enabling the first elastic member 500 to be always in a squeezed state or a stretched state, the first synchronous swing arm 410 can be squeezed on the base 100 no matter what unfolding angle the hinge mechanism is in, and the first synchronous swing arm 410 has a damping feeling all the time; or, other structural members may be additionally arranged, and when the hinge mechanism is in a certain angle range, the first synchronization swing arm 410 and the base 100 are mutually extruded, and when the hinge mechanism is in other angle ranges, the mutual extrusion between the first synchronization swing arm 410 and the base 100 is basically avoided.
More specifically, the first elastic member 500 is in a tensile or compressive state to press the first synchronization swing arm 410 and the surface of the base 100 to which the first synchronization swing arm 410 is attached. In this embodiment, the base 100 may be provided with a notch, and the first synchronization swing arm 410 and the first elastic member 500 are both disposed in the notch, so that a first sidewall of the notch of the base 100 facing the first synchronization swing arm 410 is attached to the first synchronization swing arm 410, and two ends of the first elastic member 500 respectively abut against a second sidewall of the notch of the first synchronization swing arm 410 and the base 100, and the second sidewall and the first sidewall are disposed opposite to each other along the direction of the rotation axis. Of course, there are various combinations of the positions and the connection forms of the first elastic members 500, which will not be described one by one.
In another embodiment of the present application, the hinge mechanism includes a first elastic component 500, a limiting component 240 and a positioning component, the positioning component may be a flat plate-shaped structural component, and the positioning component and the base 100 are spaced apart and fixedly disposed in the direction of the rotation axis. Specifically, an open slot may be formed in the base 100, and the positioning element may be opposite to a notch of the open slot, based on which both the first elastic element 500 and the first synchronization swing arm 410 may be disposed between the open slot of the base 100 and the positioning element, and the limiting element 240 may be disposed between the first synchronization swing arm 410 and the positioning element.
Furthermore, a plurality of first limiting protrusions (not shown in the drawings) are disposed at intervals along the circumferential direction of the rotation axis (i.e., the direction around the rotation axis) at one end of the limiting member 240 facing the first synchronous swing arm 410, and correspondingly, as shown in fig. 6, a plurality of second limiting protrusions 441 are disposed at intervals along the circumferential direction of the rotation axis at one end of the first synchronous swing arm 410 facing the limiting member 240.
Any one of the first limiting protrusions can be clamped in a gap between any two adjacent ones of the second limiting protrusions 441, and any one of the second limiting protrusions 441 can be clamped in a gap between any two adjacent ones of the first limiting protrusions 441, so that in the process that the first synchronizing swing arm 410 and the limiting member 240 relatively rotate along the circumferential direction of the rotation axis, through the first limiting protrusion and the second limiting protrusion 441, not only can the limiting member 240 and the first synchronizing swing arm 410 be in rotating fit in the circumferential direction of the rotation axis, but also the limiting member 240 and the first synchronizing swing arm 410 can be in movable fit in the direction of the rotation axis, and the movable fit specifically performs reciprocating motion along the direction of the rotation axis.
In the above embodiment, one of the limiting member 240 and the first synchronizing swing arm 410 may be connected to one end of the first elastic member 500, and one of the base 100 and the positioning member may be connected to the other end of the first elastic member 500, and according to the specific situation of the components connected to the first elastic member 500, the compression or tension state of the first elastic member 500 is set correspondingly, that is, the limiting member 240 and the first synchronizing swing arm 410 may be in a compressed state in the direction of the rotation axis of the first rotating portion. As described above, when the limiting member 240 is located between the first synchronous swing arm 410 and the positioning member, opposite ends of the first elastic member 500 can be respectively abutted between the limiting member 240 and the positioning member.
More specifically, in the matching state that the first limiting protrusion is located between two adjacent second limiting protrusions 441, and two opposite sides of the first limiting protrusion are respectively contacted with the two second limiting protrusions 441 on the two opposite sides, the first elastic member 500 can be in a natural state. Meanwhile, in any state other than the above-mentioned fitting state, the first elastic member 500 may be in a stretched or squeezed state, thereby ensuring that the first elastic member 500 has a tendency of making the first and second limiting protrusions 441 in the above-mentioned fitting state and a tendency of tending to transition to the above-mentioned fitting state.
With the above-described technical solution, if the first synchronous swing arm 410 and the limiting member 240 are not subjected to an external force, the hinge mechanism can be stably positioned at least one specific angle. Certainly, in the process of designing the specific structures of the first limiting protrusion and the second limiting protrusion 441, it is further required to ensure that when the hinge mechanism is in the unfolding state and the folding state, the first limiting protrusion and the second limiting protrusion 441 can be in the aforementioned matching state, so that the hinge mechanism can be stably hovered at least another angle between the unfolding state, the folding state and the aforementioned two states, so as to enlarge the use scene of the electronic device and improve the user experience.
As described above, in the case where the hinge mechanism is in the second state, the first connecting portion 210 and the second connecting portion 220 are both located on the side of the base 100 toward the self screen support side, that is, the hinge mechanism is suitable for a fold-in electronic apparatus. When such electronic devices are in a folded state, the hinge mechanism needs to be used to provide an accommodating space for the display screen, so as to ensure that the display screen is not squeezed by components moving relative to each other in the hinge mechanism.
Alternatively, the hinge mechanism includes a floating support 300, and the floating support 300 is disposed at a side of the base 100 toward the screen supporting side thereof, that is, the floating support 300 is located at a side of the base 100. As described above, the base 100 is a basic portion of the hinge mechanism and is located substantially in the middle of the hinge mechanism, so that the base 100 has the capability of providing a support function for the display screen, and the display screen is directly or indirectly supported on the base 100, and by locating the floating support 300 on the screen support side of the base 100, the floating support 300 can be further utilized to provide a support function for the display screen, so as to improve the supported effect of the screen.
The floating support 300 is movably connected to the base 100 in the direction of the distribution of the two, so that the floating support 300 can move toward the base 100 or away from the base 100. The distribution direction may be a direction perpendicular to the entire hinge mechanism when the hinge mechanism is in the first state, or a direction perpendicular to the display surface of the display screen in the unfolded state, and more intuitively, the distribution direction may be a direction perpendicular to the paper surface in fig. 1.
Further, in the case where the hinge mechanism is provided with the floating support 300, a second elastic member may be provided to the floating support 300, that is, the hinge mechanism disclosed in the embodiment of the present application may further include a second elastic member, which may be connected between the floating support 300 and the base 100. Specifically, the second elastic member may be assembled between the floating support 300 and the base 100 by a screw or the like, and be pressed between the screw and the base 100, providing the floating support 300 with a return elastic force.
As described above, the hinge mechanism has the first state and the second state, and in the case where the hinge mechanism includes the floating support portion 300 and the second elastic member, in the case where the hinge mechanism is in the first state, at least one of the plurality of second rotating portions 230 can press or stretch the second elastic member while supporting the floating support portion 300 to press the floating support portion 300 and the second rotating portion 230. Meanwhile, in the case where the floating support 300 is supported by the second rotating portion 230, the distance between the floating support 300 and the base 100 is relatively far, and particularly, the distance between the outer sidewall of the base 100, which is apart from the rotation axis of the first rotating portion, and the floating support 300 may be a first distance.
With the hinge mechanism in the second state, the first connecting portion 210 and the second connecting portion 220 are both located on the side of the base 100 toward the self screen supporting side. And, under the condition that the hinge mechanism is in the second state, the second rotation portion 230 avoids the floating support portion 300, and further the floating support portion 300 can move to the direction close to the base 100 under the elastic action of the second elastic member to reset, which enables the floating support portion 300 to avoid the display screen, and provides an avoiding space for the display screen, and prevents the display screen from being damaged by being squeezed in the folding process, meanwhile, the distance between the floating support portion 300 and the base 100 is reduced, so that the distance between the outer side wall of the base 100 and the floating support portion 300 is the second distance, and the second distance is smaller than the first distance.
Furthermore, under the condition that the hinge mechanism is in the second state, the second rotating portion 230 avoids the floating support 300, so that the floating support 300 can be reset under the elastic action of the second elastic member, that is, the floating support 300 moves towards the direction close to the base 100, and further the distance between the floating support 300 and the base 100 is reduced, the automation capability of the floating support 300 is improved, and the floating support 300 can be further prevented from extruding the display screen.
In the above embodiment, the floating support 300 having the capability of moving relative to the base 100 may be provided to provide the display screen with the avoidance function. Meanwhile, the floating support 300 may be used to provide a certain support function for the middle portion of the display screen. Certainly, in order to further improve the supported effect of the portion corresponding to the hinge mechanism in the display screen, optionally, the hinge mechanism disclosed in the embodiment of the present application may further include a supporting plate 610, the supporting plate 610 is connected to both the first connecting portion 210 and the second connecting portion 220, and both the first connecting portion 210 and the second connecting portion 220 are used for driving the corresponding supporting plate 610 to rotate relative to the base 100.
Under the condition that the technical scheme is adopted, when the hinge mechanism is in the first state, the support plate 610 corresponding to the first connecting part 210 and the second connecting part 220 can provide a support function for the part of the corresponding area of the display screen, so that the part of the display screen corresponding to the hinge mechanism can be basically supported by the support plate 610 and the floating support part 300 together, the integral supported effect of the display screen is improved, and the display effect and the service life of the display screen can be improved.
Specifically, the first connection portion 210 (and the second connection portion 220) and the corresponding support plate 610 may be fixedly connected, so that the support plate 610 may provide a reliable support function for the display screen. In addition, the specific size and shape of the supporting plate 610 can be determined according to the shape and size of other components in the hinge mechanism, and the like, and is not limited herein.
In the case that the hinge mechanism disclosed in the embodiment of the present application includes the support plate 610, in order to provide an avoidance space for the display screen, further, the first connection portion 210 and the corresponding support plate 610 may form a rotational connection relationship, and further, the two support portions have a relative rotation capability. Of course, since the second connection portion 220 and the first connection portion 210 have a substantially symmetrical structure, the first connection portion 210 can be referred to in the fitting relationship between the second connection portion 220 and the corresponding support plate 610.
In order to ensure that the support plate 610 can rotate relative to the first connection portion 210 when the first connection portion 210 and the support plate 610 have the capability of rotating relative to each other, the first synchronous swing arm 410 may be provided with a first hinge portion 430, the sliding sleeve 710 is provided with a first avoidance region 212, the first connection portion 210 is provided with a second hinge portion 250 and a second avoidance region 712, the second avoidance region 712 is provided opposite to the first avoidance region 212, and the support plate 610 is provided with a third hinge portion 620 and a fourth hinge portion, such that the first hinge portion 430 passes through the first avoidance region 212 and the second avoidance region 712, the first hinge portion 430 and the third hinge portion 620 are rotatably connected, and the second hinge portion 250 and the fourth hinge portion are rotatably connected in the process of assembling the support plate 610 and the first synchronous swing arm 410.
In this case, the rotation axes of the first hinge portion 430, the second hinge portion 250, the second rotation portion 230, and the like may be designed such that the support plate 610 has a capability of rotating with respect to the first connection portion 210. In more detail, the rotation axis of the third hinge part 620 may be located at a side of the rotation axis of the second rotation part 230 away from the second connection part 220, so that the support plate 610 can rotate relative to the base 100 with the rotation axis of the second rotation part 230 as a virtual axis during the rotation of the first connection part 210 relative to the base 100 with the rotation axis of the second rotation part 230; meanwhile, under the connection effect of the first hinge 430 and the third hinge 620, the first hinge 430 can move in the track of the third hinge 620, so as to achieve the purpose of enabling the support plate 610 to have the capability of rotating relative to the first connection 210. More specifically, the third hinge part 620 is provided with a rail, and a specific track of the rail may be designed according to a specific assembly condition of other components in the hinge mechanism, so that the support plate 610 can rotate relative to the first hinge part 210 while the first hinge part 430 slides along the rail of the third hinge part 620. Of course, other technical means may be adopted by those skilled in the art to enable the supporting plate 610 to rotate relative to the first connecting portion 210, such as pressing the supporting plate 610 by the display screen, or rotating the supporting plate 610 to a direction close to the first connecting portion 210 to avoid the display screen.
Under the condition that the first connecting portion 210 and the supporting plate 610 have the capability of relatively rotating, under the condition that the hinge mechanism is in the first state, the two supporting plates 610 which are oppositely arranged are supported on the base 100, and each supporting plate 610 deviates from the first surface of the base 100 and is coplanar, so that the supporting plate 610 which rotates relatively with the first connecting portion 210 (and the second connecting portion 220) can provide a reliable supporting function for the corresponding part in the display screen by being supported on the base 100.
Certainly, in the aforementioned state, there is a space between one end of each of the two adjacent supporting plates 610 close to each other and the corresponding first connecting portion 210 (and the corresponding second connecting portion 220), so as to ensure that the first connecting portion 210 can rotate relative to the corresponding supporting plate 610 in the process of switching the hinge mechanism from the first state to the second state, so that the relative rotation angle between the two adjacent supporting plates 610 is greater than the relative rotation angle between the first connecting portion 210 and the second connecting portion 220, and further, by using the outward expansion function of the supporting plates 610, an avoidance space is provided for the display screen, and the display screen is prevented from being damaged by being squeezed by the supporting plates 610 in the folding process and in the folded state.
Correspondingly, with the hinge mechanism in the second state, the first connection portion 210 and the second connection portion 220 each support the respective support plate 610, i.e., the support plate 610 corresponding to the first connection portion 210 is supported on the first connection portion 210, the support plate 610 corresponding to the second connection portion 220 is supported on the second connection portion 220, and the respective first surfaces of the two oppositely disposed support plates 610 form a flared structure, and the flare is directed toward the base 100.
