Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The following describes in detail the technical solutions disclosed in the embodiments of the present application with reference to the accompanying drawings.
As shown in fig. 1-10, embodiments of the present application disclose a folding mechanism, a stand structure, and an electronic device. The electronic device may be a folding electronic device, and the electronic device may include a first display module 610 and the above-mentioned support structure, and the support structure may include a first housing 110, a second housing 120, and the above-mentioned folding mechanism, with which the electronic device may be switched between a folded state and an unfolded state.
As shown in fig. 5, the folding mechanism disclosed in the embodiment of the present application includes a first screen support plate 210, a second screen support plate 220, a third screen support plate 230, a fourth screen support plate 240, a first housing base 310, a second housing base 320, and a base 410. In order to improve the symmetry of the folding mechanism and to improve the folding performance of the whole folding mechanism, the structures of the first screen support plate 210 and the second screen support plate 220 may be symmetrically arranged and respectively arranged at two opposite sides of the base 410, and the structures of the third screen support plate 230 and the fourth screen support plate 240 are symmetrically arranged and respectively arranged at two opposite sides of the base 410, wherein the third screen support plate 230 is arranged at the same side as the first screen support plate 210, and the fourth screen support plate 240 is arranged at the same side as the second screen support plate 220; correspondingly, the first housing seat 310 and the second housing seat 320 are symmetrically disposed, and the first rotating portion 412 on the base 410 and engaged with the first housing seat 310 and the first rotating portion 412 on the base 410 and engaged with the second housing seat 320 are also symmetrically disposed.
The base 410 is a basic structural component of the folding mechanism, and the base 410 can provide a mounting base for other components of the folding mechanism, thereby allowing the other components of the folding mechanism to be mounted directly or indirectly on the base 410. Optionally, the base 410 is a sheet member to reduce the footprint. Specifically, the base 410 may be a sheet metal piece that enables the base 410 to have sufficient strength at a smaller thickness without affecting the support performance of the base 410.
The base 410 is provided with a plurality of first rotating parts 412, and the first housing base 310 and the second housing base 320 each include a second rotating part 302, and the plurality of second rotating parts 302 can be mutually matched with the plurality of first rotating parts 412 in a one-to-one correspondence manner, so that the first housing base 310 and the second housing base 320 can form a stable rotation matching relationship with the base 410, and the first housing base 310 can be integrally connected with the second housing base 320 through the base 410.
Specifically, the number of the first rotating parts 412 may be two, one of the two first rotating parts 412 is matched with the second rotating part 302 of the first housing seat 310, and the other one is matched with the second rotating part 302 of the second housing seat 320, in which case, the two second rotating parts 302 may be symmetrically arranged on the base 410 to ensure that the folding mechanism has better folding performance. Of course, in the case where the number of the first rotating parts 412 engaged with the first housing seat 310 is plural, the aforementioned plural first rotating parts 412 may be arranged at intervals in the axial direction of the base 410, that is, the rotational axial direction of the second rotating part 302. Correspondingly, a plurality of first rotating portions 412 may be disposed in cooperation with the second housing seat 320. By adopting the above technical scheme, the reliability of the connection relationship and the rotation fit relationship between the first housing seat 310 and the second housing seat 320 can be further improved. The rotation axis of the second rotation portion 302 may be a direction a in fig. 1.
The first rotating portion 412 and the second rotating portion 302 are mutually matched rotating structural members, for example, the two may be shaft hole matched structures. In another embodiment of the present application, one of the first rotating portion 412 and the second rotating portion 302 may be an arc-shaped groove-like structure, and the other may be an arc-shaped block-like structure, in which case the stability of the rotation fit relationship between the first rotating portion 412 and the second rotating portion 302 may be improved to some extent. Also, the base 410 may be an arcuate structure to provide a better forming basis for the first rotating portion 412 and to reduce the overall size of the base 410.
As shown in fig. 1 to 5, the first housing base 310 is disposed on the first screen support plate 210, and the first screen support plate 210 is in a rotating fit with the first housing base 310. The second housing seat 320 is disposed on the second screen support plate 220, and the second screen support plate 220 is in rotation fit with the second housing seat 320. In the case where the above folding mechanism is applied to an electronic apparatus, both the first screen support plate 210 and the second screen support plate 220 can provide a supporting function for the first display module 610. In order to prevent the existence of the first housing seat 310 and the second housing seat 320 from affecting the supported effect of the first display module 610, the first housing seat 310 is disposed on a side of the first screen support plate 210 facing away from the first display module 610, and correspondingly, the second housing seat 320 is disposed on a side of the second screen support plate 220 facing away from the first display module 610. Alternatively, the first housing seat 310 and the first screen support plate 210, and the second housing seat 320 and the second screen support plate 220 may be rotatably coupled to each other through a rotation structure such as a shaft hole. In addition, the maximum relative rotation angle between the first screen support plate 210 and the first housing seat 310 may be equal to the maximum relative rotation angle between the second screen support plate 220 and the second housing seat 320, so that the symmetry of the whole folding mechanism is better, and the overall performance of the folding mechanism is improved.
Optionally, the third screen support plate 230 is rotatably mounted on the first screen support plate 210, so that the first screen support plate 210 rotates along with the first housing seat 310 and simultaneously drives the third screen support plate 230 to rotate; correspondingly, the fourth screen support plate 240 is rotatably mounted on the second screen support plate 220, so that the fourth screen support plate 240 can be driven to rotate together during the rotation of the second screen support plate 220 along with the second housing seat 320. Specifically, the shapes of the third screen support plate 230 and the fourth screen support plate 240 may be determined according to practical requirements, for example, both may be long-strip plate-shaped structural members, and by means of the shaft hole matching structure, the third screen support plate 230 may be rotatably mounted on the first screen support plate 210, and the fourth screen support plate 240 may be correspondingly rotatably mounted on the second screen support plate 220. Of course, the third screen supporting plate 230 and the fourth screen supporting plate 240 may have other shapes, and any corresponding two of the above may also form a rotation fit relationship through other rotation members, which is not listed here in order to avoid brevity.
The folding mechanism has an unfolded state and a folded state, and the entire folding mechanism can be switched between the folded state and the unfolded state by relatively moving both the first housing seat 310 and the second housing seat 320 based on the base 410. In addition, during the state switching process of the folding mechanism, not only the first screen support plate 210 and the second screen support plate 220 move relative to the base 410, but also, as shown in fig. 9 and 10, relative movement occurs between the first screen support plate 210 and the first housing base 310, and between the second screen support plate 220 and the second housing base 320.
The first screen support plate 210 and the second screen support plate 220 each have a first side 203 and a second side that are opposite to each other, and the first screen support plate 210 and the second screen support plate 220 each have a first surface 201 and a second surface 202 that are opposite to each other, and the first surfaces 201 of the first screen support plate 210 and the second screen support plate 220 are disposed away from the base 410, that is, the first screen support plate 210 and the second screen support plate 220 are disposed on the same side of the base 410, each first surface 201 serves as a screen support surface to support the first display module 610, and the second surface 202 that is opposite to the first surface 201 is disposed toward the base 410 in the first screen support plate 210 and the second screen support plate 220. Correspondingly, the third screen support plate 230 and the fourth screen support plate 240 are also correspondingly provided with a first surface 201 and a second surface 202,
referring to fig. 9 and 10, in the unfolded state, the respective first sides 203 of the first and second screen support plates 210 and 220 are each located between the respective second sides, and the respective first, second, third and fourth screen support plates 210, 220, 230, 240 are disposed flush away from the first surface 201 of the base 410. Also, in the unfolded state, the third and fourth screen support plates 230 and 240 are located between the first and second screen support plates 210 and 220, and in particular, the third and fourth screen support plates 230 and 240 may be integrally located between the second sides of the first and second screen support plates 210 and 220, or the third and fourth screen support plates 230 and 240 may be located between a partial structure of the first screen support plate 210 and a corresponding partial structure of the second screen support plate 220.
As shown in fig. 10, in the folded state, the distance between the first sides 203 of the first and second screen support plates 210 and 220 is greater than the distance between the second sides of the first and second screen support plates 210 and 220.
In detail, in the unfolded state, the first screen support plate 210, the second screen support plate 220, the third screen support plate 230 and the fourth screen support plate 240 are flush, so that the four can provide support for the first display module 610 and the like, and the first display module 610 can be ensured to stably maintain the unfolded state. Referring to fig. 9 and 10, in the process of switching the folding mechanism from the unfolded state to the folded state, the angle of relative rotation of the first screen support plate 210 and the second screen support plate 220 is greater than 180 °, so that the distance between the respective first sides 203 of the first screen support plate 210 and the second screen support plate 220 is greater than the distance between the respective second sides in the folded state.
In addition, as described above, the folding mechanism may be applied to the stand structure, and when the stand structure is folded to a folded state along with the folding mechanism, as shown in fig. 10, the first housing 110 and the second housing 120 are stacked, and the screen supporting surfaces of the first housing 110 and the second housing 120 are disposed in parallel, so that two portions of the first display module 610 supported by the first housing 110 and the second housing 120 can be parallel to each other. In the process of assembling the first screen support plate 210 and the first housing seat 310, a rotational connection structure (such as a rotational assembly mentioned below) between the first screen support plate 210 and the first housing seat 310 may be disposed at a position of the first screen support plate 210 near the first side 203 thereof, so that when the first screen support plate 210 rotates relative to the first housing seat 310, the first screen support plate 210 can substantially take the second side thereof as an axis, thereby preventing the first side 203 of the first screen support plate 210 from rotating in a direction approaching the first housing seat 310, and simultaneously ensuring that the second side of the first screen support plate 210 always provides a better supporting effect for the components such as the first display module 610. Accordingly, the above embodiments can also be referred to in the process of assembling the second screen support plate 220 and the second housing seat 320.
Based on the above, as shown in fig. 10, the interval between the second sides of the first and second screen support plates 210 and 220 is equal to or substantially equal to the interval between the screen support surfaces of the first and second housings 110 and 120 in the bracket structure in the folded state. Accordingly, it can also be considered that the interval between the first side edges 203 of the first and second screen support plates 210 and 220, respectively, is greater than the interval between the first and second housings 110 and 120 in the folded state.
More specifically, a specific value of the interval between the first side edges 203 of the first screen support plate 210 and the second screen support plate 220 in the folded state in the folding mechanism may be determined according to parameters such as the widths of the first screen support plate 210 and the second screen support plate 220, which are directions perpendicular to the rotation axis direction of the second rotation portion 302, more specifically, may be direction B in fig. 9.
It should be noted that, in order to ensure that the relative rotation angle between the first screen support plate 210 and the second screen support plate 220 can exceed 180 °, it is necessary to ensure that the first screen support plate 210 can move relative to the first housing seat 310, and it is necessary to ensure that the second screen support plate 220 can move relative to the second housing seat 320. More specifically, in order to achieve the foregoing object, parameters such as specific structures and/or mounting positions of the components of the base 410, the first housing seat 310, the second housing seat 320, and the like may be limited.
Taking the first screen support plate 210 as an example, in the unfolded state, as shown in fig. 9, and in combination with fig. 10, it is necessary to ensure that the portion between the rotational connection position of the first screen support plate 210 and the first housing seat 310 and the first side 203 of the first screen support plate 210 is spaced from the first housing seat 310, the base 410, the first housing 110, and the like, so as to provide a space for avoiding the rotation of the first screen support plate 210 in a direction approaching the first housing seat 310. Similarly, the same is true in designing and arranging the second housing seat 320, the base 410, the second housing 120, and the like corresponding to the second screen support plate 220.
In order to minimize the thickness of the entire folding structure and thus the overall thickness of the electronic device during the design of the folding mechanism, the interval between the first screen support plate 210 and the base 410 in the unfolded state may be appropriately reduced, in which case, since the third screen support plate 230 and the fourth screen support plate 240 are disposed between the first screen support plate 210 and the second screen support plate 220, the base 410 may have a preset-sized interval between the center of the direction B and the first side 203 of the first screen support plate 210 in fig. 9 in the direction B of fig. 9, so that the first screen support plate 210 and the base 410 may be prevented from interfering with each other as much as possible during the rotation of the first screen support plate 210 relative to the base 410.
As described above, the third and fourth screen support plates 230 and 240 may be rotated together with the first and second screen support plates 210 and 220, respectively, in the course of rotating the same from the unfolded state to the folded state. Further, in the above-described rotation process, as shown in fig. 10, by enabling the third screen support plate 230 to rotate relative to the first screen support plate 210, even if the third screen support plate 230 is interfered by the base 410 or the like, the rotation process of the first screen support plate 210 relative to the base 410 is not hindered, and the first screen support plate 210 is ensured to be rotatable to a predetermined position. Correspondingly, the fourth screen support plate 240 may also be designed correspondingly with reference to the third screen support plate 230.
The embodiment of the application provides a folding mechanism, which includes a first screen support plate 210, a second screen support plate 220, a third screen support plate 230, a fourth screen support plate 240, a first housing base 310, a second housing base 320 and a base 410, wherein the first screen support plate 210 is rotationally connected with the first housing base 310, the second screen support plate 220 is rotationally connected with the second housing base 320, the third screen support plate 230 is rotationally connected with the first screen support plate 210, and the fourth screen support plate 240 is rotationally connected with the second screen support plate 220. The first housing seat 310 and the second housing seat 320 are rotatably connected to the base 410, and the first screen support plate 210 and the second screen support plate 220 not only can rotate with the first housing seat 310 and the second housing seat 320, but also can rotate with respect to the first housing seat 310, and the second screen support plate 220 can rotate with respect to the second housing seat 320, so that the folding mechanism can be switched between a folded state and an unfolded state.
In the unfolded state, the first side edges 203 of the first screen support plate 210 and the second screen support plate 220 are located between the second side edges of the first screen support plate and the second screen support plate, and the third screen support plate 230 and the fourth screen support plate 240 are located between the first screen support plate 210 and the second screen support plate 220, and the first screen support plate 210, the second screen support plate 220, the third screen support plate 230 and the fourth screen support plate 240 are arranged flush with the first surface 201 of the base 410, so as to provide a reliable supporting function for the first display module 610 of the electronic device, and ensure that the first display module 610 can be in a flattened state, and provide a larger display area for a user.
In the folded state, the space between the respective first sides 203 of the first screen support plate 210 and the second screen support plate 220 is larger than the space between the respective second sides, so that the first screen support plate 210 and the second screen support plate 220 form a flaring structure, and the flaring of the flaring structure faces the base 410. In addition, in the use process of the electronic equipment adopting the folding mechanism, the electronic equipment in a folded state is relatively small in overall size, relatively high in portability degree and convenient for users to carry.
In addition, by providing the third screen support plate 230 and the fourth screen support plate 240, gaps between the first screen support plate 210 and the third screen support plate 230, between the second screen support plate 220 and the fourth screen support plate 240, and between the third screen support plate 230 and the fourth screen support plate 240 are relatively smaller, and the space between the first screen support plate 210 and the second screen support plate 220 and the base 410 in the folding mechanism in the unfolded state can be reduced to some extent, the thickness of the folding mechanism is reduced, and thus the thickness of an electronic device employing the folding mechanism is reduced. Meanwhile, the base 410 and the first display module 610 of the electronic device may be separated by the third screen support plate 230 and the fourth screen support plate 240, thereby preventing the first display module 610 from being damaged and improving the service life of the first display module.
Optionally, as shown in fig. 1 and fig. 3, the folding mechanism provided in the embodiment of the present application may further include a first connection shaft 751, a second connection shaft 752, a first synchronization swing arm 741 and a second synchronization swing arm 742, where the first synchronization swing arm 741 is in a limit fit with the first connection shaft 751 in the rotation direction of the second rotation portion 302, and the second synchronization swing arm 742 is in a limit fit with the second connection shaft 752 in the rotation direction of the second rotation portion 302. Specifically, the first connection shaft 751 and the second connection shaft 752 may be rotatably connected to the base 410, the first synchronization swing arm 741 may be sleeved on the first connection shaft 751, and the second synchronization swing arm 742 may be sleeved on the second connection shaft 752, and the two groups of components may be correspondingly formed into an interference fit relationship. In another embodiment of the present application, the first synchronization swing arm 741 and the first connecting shaft 751 may be formed in a limited fit relationship by means of a key connection, and correspondingly, the second synchronization swing arm 742 and the second connecting shaft 752 may be formed in a limited fit relationship by means of a key connection, which may further improve the stability of the above-mentioned limited fit relationship.
Meanwhile, the first synchronization swing arm 741 is matched with the first housing base 310, the second synchronization swing arm 742 is matched with the second housing base 320, the first synchronization swing arm 741 and the second synchronization swing arm 742 are connected through a gear synchronization mechanism, and the first housing base 310 and the second housing base 320 synchronously rotate through the gear synchronization mechanism. Under the condition of adopting the technical scheme, the capability of synchronous rotation between the first screen support plate 210 and the second screen support plate 220 can be ensured, so that no matter which one of the two is driven, the other one can be driven to rotate relative to the base 410 through a gear synchronous mechanism and the like, the rotation angles of the first screen support plate 210 and the second screen support plate 220 relative to the base 410 are always the same, and the comprehensive performance of the whole folding mechanism is improved.
Specifically, the fitting relationship between the first swing synchronization arm 741 and the first housing seat 310 may be determined based on actual parameters such as the directions in which the rotational axes of the first connection shaft 751 and the second rotation section 302 are located. For example, when the axial direction of the first connection shaft 751 and the rotational axial direction of the first rotating unit 412 overlap each other, the first synchronization swing arm 741 and the first housing seat 310 may be fixed to each other. In another embodiment of the present application, the rotational axis of the first connection shaft 751 may be misaligned with the rotational axis of the second rotating portion 302, in which case it is necessary to enable relative movement between the first swing synchronization arm 741 and the first housing seat 310.
Specifically, by providing a sliding groove on one of the first swing arm 741 and the first housing seat 310, and providing a sliding rod on the other, the sliding rod cooperates with the sliding groove, so that even if the rotation axis of the first connecting shaft 751 does not coincide with the rotation axis of the second rotating portion 302, it is ensured that the first housing seat 310 can drive the first swing arm 741 to rotate together with the base 410. Further, under the action of the gear synchronization mechanism, the second synchronization swing arm 742 can correspondingly rotate and drive the second housing seat 320 to rotate relative to the base 410, so as to achieve the purpose of synchronous rotation of the first screen support plate 210 and the second screen support plate 220.
Alternatively, the gear synchronizing mechanism includes a first engagement tooth 781 provided on the first connection shaft 751, a second engagement tooth 782 provided on the second connection shaft 752, a first gear 791 and a second gear 792, the first engagement tooth 781 being engaged with the first gear 791, the first gear 791 being engaged with the second gear 792, the second gear 792 being engaged with the second engagement tooth 782. With the above technical solution, the first housing seat 310 and the second housing seat 320 can be rotated synchronously by using relatively few components.
Specifically, the first connection shaft 751 and the first engagement teeth 781 may constitute a gear shaft, correspondingly, the second connection shaft 752 and the second engagement teeth 782 may also constitute a gear shaft, and since the rotation angle of each of the first housing seat 310 and the second housing seat 320 with respect to the base 410 is generally not greater than 180 °, the first engagement teeth 781 may cover one-fourth turn to one-half turn on the first connection shaft 751, and correspondingly, the second engagement teeth 782 may cover one-fourth turn to one-half turn on the second connection shaft 752, which may substantially ensure that the first engagement teeth 781 and the second engagement teeth 782 may provide a reliable synchronization effect, and may reduce production costs.
Further, the folding mechanism may further include a first cam sleeve 731, a second cam sleeve 732, and an elastic member 720, the first cam sleeve 731 and the second cam sleeve 732 are sleeved on the first connection shaft 751, the first cam sleeve 731 is fixed on the first synchronization swing arm 741, the second cam sleeve 732 is rotatably engaged with the first connection shaft 751 in a rotation direction of the second rotation portion 302, and the elastic member 720 is in a stretched state or a contracted state under the condition that the first cam sleeve 731 and the second cam sleeve 732 are relatively rotated.
Specifically, the specific structures of the first cam sleeve 731 and the second cam sleeve 732 may be the same, and they are buckled, and in the process of rotating the first cam sleeve 731 and the second cam sleeve 732 relatively, the maximum distance between the first cam sleeve 731 and the second cam sleeve 732 may be greater than the initial distance (i.e., the minimum distance) between the first cam sleeve 731 and the second cam sleeve 732, in this case, the elastic member 720 may be stretched or compressed, so that the elastic member 720 may apply an elastic restoring force to the first cam sleeve 731 and/or the second cam sleeve 732, so as to promote the first cam sleeve 731 and the second cam sleeve 732 to restore to the buckled state, i.e., the state with the minimum distance between the first cam sleeve 731 and the second cam sleeve 732.
By adopting the above technical scheme, the relative position between the first cam sleeve 731 and the second cam sleeve 732 in the buckling state can be designed, so that when the folding mechanism is in the folding state and the unfolding state, the first cam sleeve 731 and the second cam sleeve 732 are both in the buckling state, and as long as the folding mechanism is no longer in the folding state or the unfolding state, the space between the first cam sleeve 731 and the second cam sleeve 732 is increased due to relative rotation, so that the elastic piece 720 is stretched or compressed. Therefore, under the above technical scheme, the folding mechanism can be easily kept in the unfolded state and the folded state by the elastic member 720, and the unfolded state or the folded state of the folding mechanism can be prevented from being damaged by small external force, which is inconvenient for users.
Optionally, the folding mechanism further comprises a mounting member 714, wherein the mounting member 714 is fixed to the base 410, and the mounting member 714 is fixed to the base 410 by welding or connecting a connecting member. The mounting member 714 is provided with a first limiting member 711 and a second limiting member 712 which are opposite and fixed along the rotation axis of the second rotating portion 302, the first cam sleeve 731, the second cam sleeve 732 and the elastic member 720 are all disposed between the first limiting member 711 and the second limiting member 712, and the elastic member 720 is disposed on a side of the second cam sleeve 732 facing away from the first cam sleeve 731. Under the condition of adopting the technical scheme, the first limiting piece 711 and the second limiting piece 712 can provide the function of a positioning base, so that on one hand, the reliability of the elastic piece 720 can be improved, and on the other hand, the installation difficulty of the elastic piece 720 can be reduced.
In the above-described embodiment, the first cam sleeve 731 and the second cam sleeve 732 are rotated relative to each other, that is, the elastic member 720 is compressed, so that the elastic member 720 applies an elastic force to the first cam sleeve 731 and the second cam sleeve 732 to return the same. To further prevent the difficulty of maintaining the folding mechanism in the folded state and the unfolded state, the elastic member 720 may have a pre-tightening force, that is, the elastic member 720 may be in a compressed state in a state in which the first cam sleeve 731 and the second cam sleeve 732 are engaged with each other.
Specifically, the first cam sleeve 731 and the first swing arm 741 may be formed by welding or integrally molding, and the first swing arm 741 may be brought into a limit fit relationship with the first connecting shaft 751 in the rotation direction of the second rotation portion 302 through the first cam sleeve 731. More specifically, the first cam sleeve 731 and the first connection shaft 751 may be connected to each other by a key connection, and the inner circumferential surface of the second cam sleeve 732 may be a circular structure, so as to ensure that the second cam sleeve 732 can normally rotate with respect to the first connection shaft 751, and of course, in order to prevent the second cam sleeve 732 from rotating with the first connection shaft 751 together with the first cam sleeve 731 during the rotation of the first connection shaft 751 with the first swing arm 741, the second cam sleeve 732 may be optionally engaged with the base 410 in a limited manner in the rotation direction of the second rotation part 302.
In addition, the first limiting member 711, the second limiting member 712 and the mounting member 714 may be formed in an integrally formed manner, so as to improve the stability of the connection relationship between the three. The first and second stoppers 711 and 712 may be provided with coupling holes such that opposite ends of the first and second connection shafts 751 and 752 are respectively mounted on the first and second stoppers 711 and 712. More specifically, the fitting holes may be through holes, and the first connection shaft 751 and the second connection shaft 752 may be led out of the first limiting member 711 and the second limiting member 712, and then, by means of the structure of the snap spring 770 or the like, the first connection shaft 751 and the second connection shaft 752 may be brought into a stable rotational fit relationship with the mounting member 714. The first gear 791 and the second gear 792 may be rotatably mounted on the first stopper 711 or the second stopper 712 by a coupling shaft or the like, so that the first gear 791 and the second gear 792 can be stably engaged with the first engagement tooth 781 and the second engagement tooth 782.
Optionally, the mounting piece 714 is further provided with a third limiting piece 713, where the third limiting piece 713 is located between the first limiting piece 711 and the second limiting piece 712, specifically, the third limiting piece 713 may also be an integrally formed component of the mounting piece 714, and the third limiting piece 713 may also be provided with a through hole for the first connecting shaft 751 and the second connecting shaft 752 to pass through. A first cam sleeve 731, a second cam sleeve 732, and an elastic member 720 are provided between the first stopper 711 and the third stopper 713, and between the second stopper 712 and the third stopper 713. With the adoption of the scheme, the stability of the folding mechanism in the folded state and the unfolded state can be further improved. Specifically, the spacing between the first limiting member 711 and the third limiting member 713, and the spacing between the second limiting member 712 and the third limiting member 713 may be the same, in which case the parameters such as the structure of each first cam sleeve 731 may be the same, the parameters such as the structure of each second cam sleeve 732 may be the same, and the parameters such as the structure of each elastic member 720 may be the same, thereby reducing the difficulty of spare parts and assembly.
Alternatively, the first and second swing arms 741 and 742 are each fixed with a first cam sleeve 731, and each first cam sleeve 731 is provided with a second cam sleeve 732 and an elastic member 720. That is, in the case where the folding mechanism is in the unfolded and folded state, both the side of the first swing arm 741 and the side of the second swing arm 742 may be elastically acted on by the elastic member 720, which may prevent the folding mechanism from being out of the unfolded state and the folded state, thereby improving the ability of the folding mechanism to stably maintain the unfolded state and the folded state. Of course, in both the first and second swing arms 741 and 742, a plurality of sets of the first and second cam sleeves 731 and 732 and the elastic member 720 may be disposed to further enhance the ability of the folding mechanism to maintain the folded state and the unfolded state.
As described above, by bringing the second cam sleeve 732 into a desired limit relationship with the base 410 or the like, the second cam sleeve 732 is prevented from rotating with the first cam sleeve 731 when the first cam sleeve 731 is rotated, and the first cam sleeve 731 and the second cam sleeve 732 cannot be moved axially. In the above-described embodiment, when the first and second swing arms 741 and 742 are each provided with the first cam sleeve 731, the connecting rod 733 may be provided between the second cam sleeves 732 that are respectively engaged with the two first cam sleeves 731, and in this case, the second cam sleeves 732 may be mounted on the first and second connecting shafts 751 and 752, respectively, so as to reduce the difficulty of assembly, and the two second cam sleeves 732 may be provided with the ability to operate synchronously, so that the ability to maintain the folding mechanism in the folded state and the unfolded state is further improved, and in addition, the two second cam sleeves 732 are connected by the connecting rod 733, so that in the process of designing and assembling the second cam sleeves 732, no limit structure need to be separately provided for the second cam sleeves 732, and under the combined action of the connecting rod 733 and the two second cam sleeves 732, the second cam sleeves 732 may be rotated with respect to the first and second connecting shafts 751 and 752, respectively, so that the second cam sleeves 732 may not rotate with the rotation of the first cam sleeve 731 is basically ensured.
As described above, the third screen support plate 230 and the fourth screen support plate 240 may each be a long strip-shaped plate-like structural member, and the first screen support plate 210, the second screen support plate 220, the third screen support plate 230, and the fourth screen support plate 240 may be made equal in size in the direction a in fig. 1, that is, the foregoing four are disposed side by side. Optionally, in the case that the folding mechanism includes the above-mentioned first synchronization swing arm 741 and the second synchronization swing arm 742, in another embodiment of the present application, as shown in fig. 5, the first screen support plate 210 and the second screen support plate 220 are both provided with a first avoidance gap, the third screen support plate 230 is rotatably mounted to the first avoidance gap of the first screen support plate 210, the fourth screen support plate is rotatably mounted to the second avoidance gap of the second screen support plate, the side edge of the third screen support plate 230 is flush with the first side edge 203 of the first screen support plate 210, and the side edge of the fourth screen support plate 240 is flush with the first side edge 203 of the second screen support plate 220, so that the first screen support plate 210 and the third screen support plate 230, and the second screen support plate 220 and the fourth screen support plate 240 can correspondingly form a structure with rectangular or approximately rectangular outer contours, so as to provide a reliable supporting function for the first display module 610 in the electronic device.
Also, the third screen support plate 230 may be disposed opposite to the first swing synchronization arm 741, and the fourth screen support plate 240 may be disposed opposite to the second swing synchronization arm 742, so that even though the distance between the first swing synchronization arm 741 and the second swing synchronization arm 742 and the first screen support plate 210 and the second screen support plate 220 in the thickness direction of the base 410 is relatively small, the first screen support plate 210 and the second screen support plate 220 may be provided with a dodging effect by the third screen support plate 230 and the fourth screen support plate 240, respectively, to ensure that the first screen support plate 210 and the second screen support plate 220 can be rotated to the state shown in fig. 10. Of course, in the above technical solution, the structure of the first housing seat 310 and the second housing seat 320 matching with the base 410 is also required to be designed, so that the positions of the first housing seat 310, the second housing seat 320 and the base 410 corresponding to the two positions do not hinder the relative rotation between the first screen support plate 210 and the second screen support plate 220.
In addition, in the case where the number of the first and second swing arms 741 and 742 is plural, the first avoidance notches of the first and second screen support plates 210 and 220 may be plural, and correspondingly, the number of the third and fourth screen support plates 230 and 240 may be plural.
As described above, the first screen support plate 210 and the third screen support plate 230 may form a rotation fit relationship through the shaft hole structural member, alternatively, the opposite ends of the first avoidance gap of the first screen support plate 210 may be provided with the fifth rotation portion 530, the opposite ends of the third screen support plate 230 may be provided with the sixth rotation portion 540, one of the fifth rotation portion 530 and the sixth rotation portion 540 is provided with the arc slot, the other one includes the arc insert, the arc slot is rotationally connected with the arc insert, and the purpose of rotational connection between the first screen support plate 210 and the third screen support plate 230 is achieved through the arc insert and the arc insert with larger fit area, so that the reliable rotation connection relationship between the two can be ensured. Correspondingly, the rotational connection between the second screen support plate 220 and the fourth screen support plate 240 may also be formed by the fifth rotating portion 530 and the sixth rotating portion 540.
Further, as shown in fig. 1 to 6, the folding mechanism may further include a fifth screen support plate 250, the fifth screen support plate 250 being mounted on the base 410, alternatively, the fifth screen support plate 250 may be fixed to the base 410 by means of bonding or connection, etc. The third screen support plate 230 and the fourth screen support plate 240 are respectively provided with a second avoidance gap, and in the unfolded state, the fifth screen support plate 250 is embedded into the second avoidance gap of the third screen support plate 230 and the second avoidance gap of the fourth screen support plate 240. Under the condition of adopting the above technical solution, the size of the gap between the third screen support plate 230 and the fourth screen support plate 240 can be further reduced, by means of the second avoidance gaps of the third screen support plate 230 and the fourth screen support plate 240, in the process that the third screen support plate 230 and the fourth screen support plate 240 rotate relative to the base 410, the third screen support plate 230 and the fourth screen support plate 240 can better avoid the structures such as the base 410, the first synchronous swing arm 741 and the second synchronous swing arm 742, and the maximum angle that the third screen support plate 230 and the fourth screen support plate 240 can rotate relative to the base 410 is enlarged, and then the gap between the third screen support plate 230 and the fourth screen support plate 240 can be designed to be smaller, and the supporting effect on the components such as the first display module 610 is improved.
As described above, the fifth screen support plate 250 may be fixed to the base 410, and in another embodiment of the present application, the fifth screen support plate 250 may be movably coupled to the base 410 in its thickness direction, and in particular, the fifth screen support plate 250 may be movably mounted to the base 410 by pins, thereby allowing the fifth screen support plate 250 to move relative to the base 410 during operation of the folding mechanism.
Based on the above, in the unfolded state, the fifth screen support plate 250 has a first pitch from the base 410 in the thickness direction thereof; in the folded state, the fifth screen support plate 250 has a second interval with the base 410 in the thickness direction thereof, the second interval being smaller than the first interval. Colloquially, the fifth screen support plate 250 moves in a direction approaching the base 410 during the switching of the folding mechanism from the unfolded state to the folded state; the fifth screen support plate 250 moves away from the base 410 during the switching of the folding mechanism from the folded state to the unfolded state. By adopting the technical scheme, the accommodating space of the folding mechanism in the folded state can be further enlarged, so that the problem that the first display module is folded to generate folds is further prevented.
In addition, an elastic member or the like may be provided between the fifth screen support plate 250 and the base 410, so that the first display module may be pressed against the fifth screen support plate 250 to move in a direction approaching the base 410 in the process of being folded, and the elastic member may be driven to return by its own elastic force in the process of gradually flattening the first display module. Alternatively, a power driving member may be disposed between the fifth screen support plate 250 and the base 410, and the power driving member may drive the fifth screen support plate 250 and the base 410 to move toward or away from each other.
In addition, as described above, the first screen support plate 210 may also rotate relative to the first housing base 310 during rotation of the first housing base 310 relative to the base 410. More specifically, the driving force may be lifted by the flexible display screen in the electronic device during the rotation of the first screen support plate 210 toward the first housing seat 310; for the rotation of the first screen support plate 210 away from the first housing seat 310, the first screen support plate 210 may be driven by means of an elastic restoring force by providing an elastic member in the folding mechanism, so that when the first housing seat 310 and the second housing seat 320 rotate to the unfolded state, the first screen support plate 210 may be flush with the screen support surface of the first housing 110, so as to provide a supporting function for the flexible display screen together. In another embodiment of the present application, a power driving device, such as an electric motor, may be further disposed between the first screen support plate 210 and the first housing 110, and the first screen support plate 210 and the first housing seat 310 may be driven to rotate opposite to or opposite to each other by the power driving device. Of course, the second housing seat 320 and the second screen support plate 220 may be designed and manufactured according to any of the above-mentioned technical schemes.
Based on the above embodiment, optionally, as shown in fig. 5 and 10, a side of the third screen support plate 230 and a side of the fourth screen support plate 240, which are close to the fifth screen support plate 250, are respectively provided with a first overlapping edge, and opposite sides of the fifth screen support plate 250 are respectively provided with a second overlapping edge, and in the unfolded state, each second overlapping edge overlaps the corresponding first overlapping edge. Specifically, the shapes and sizes of the first and second overlapping edges may be mutually adapted, and specifically, the first and second overlapping edges may be stepped structural members to promote the stability of the fifth screen support plate 250 overlapping the third and fourth screen support plates 230 and 240.
In the case of the above-described technical solution, the fifth screen support plate 250 may overlap the third screen support plate 230 and the fourth screen support plate 240 in the unfolded state. In this case, the third screen support plate 230 and the fourth screen support plate 240 can also provide driving force for the movement of the fifth screen support plate 250 relative to the base 410, and further, under the circumstance that the first screen support plate 210 and the second screen support plate 220 can automatically rotate along with the movement of the folding mechanism, it is not necessary to provide driving parts for the fifth screen support plate 250, on the one hand, the number of parts in the folding mechanism is reduced, on the other hand, the assembly efficiency of the folding mechanism can be improved, and the production cost is reduced.
Optionally, as shown in fig. 1 and fig. 10, the folding mechanism further includes a cover 420, where the cover 420 is fixedly connected to a side of the base 410 away from the first screen support plate 210, and the cover 420 can provide protection for the base 410, and can be used to shield the folding mechanism, so that when the folding mechanism is applied to an electronic device, the number of exposed parts of the electronic device is reduced as much as possible, on one hand, the appearance performance of the electronic device is improved, on the other hand, the dustproof and waterproof performance of the electronic device is also improved, and the reliability of the electronic device is improved. The cover 420 may be fixed on the base 410 by means of adhesion or the like, and in another embodiment of the present application, the base 410 and the cover 420 may be detachably and fixedly connected together by a threaded connection member such as a screw, so as to improve connection reliability between the two.
Meanwhile, in the folded state, the projection of the cover 420 in the plane where the distribution direction of the first screen support plate 210 and the second screen support plate 220 and the rotation axis of the second rotating portion 302 are located covers the third screen support plate 230, the fourth screen support plate 240, the first housing seat 310, the second housing seat 320 and the base 410, so as to ensure that the cover 420 has a better shielding effect. It should be noted that the distribution direction of the first screen support plate 210 and the second screen support plate 220 may be the direction B in fig. 9.
Specifically, by designing parameters such as the structure, the size, the installation position, and the like of the cover 420 according to parameters such as the specific structure and the size of other components in the folding mechanism, when the folding mechanism is in a folded state, the folding mechanism is seen from the side where the cover 420 is located, and the third screen support plate 230, the fourth screen support plate 240, the first housing seat 310, the second housing seat 320, and the base 410 in the folding mechanism can be all blocked by the cover 420. More specifically, in order to improve the shielding effect of the cover 420 on other components, as shown in fig. 7, the cover 420 may be an arc-shaped structural member, which may further improve the tightness of connection between the cover 420 and the first housing 110 and the second housing 120 in the bracket structure, and further improve the sealing performance of the bracket structure and the electronic device.
Further, as shown in fig. 2 and 3, the first housing seat 310 and/or the second housing seat 320 includes a relief structure provided with a relief groove 303, and in the unfolded state, the side edge of the cover 420 is received in the relief groove 303. Specifically, the parameters such as the position and the size of the avoiding groove 303 can be flexibly determined according to the parameters such as the extending position and the thickness of the cover 420, which are not limited herein.
More specifically, the first housing seat 310 and the second housing seat 320 are both provided with the avoiding groove 303, in this case, an abdication space can be provided for the side edges of the cover body 420 by means of the avoiding groove 303, so that the two side edges of the cover body 420, which are oppositely arranged along the direction B in fig. 9, can extend relatively more toward the direction close to the first screen support plate 210 and the second screen support plate 220, and the bending degree of the cover body 420 is further improved, so that when the folding mechanism is in the folded state, the gap between the cover body 420 and the first housing 110 and the second housing 120 is smaller, and the matching reliability between the cover body 420 and the first housing 110 and the second housing 120 is higher.
Taking the first housing seat 310 as an example, in the case where the first housing seat 310 is provided with the avoidance structure, in order to ensure that the structural strength of the first housing seat 310 can still meet the use requirement, as shown in fig. 3, the position where the avoidance structure is located may be protruded to a side deviating from the avoidance groove 303. Based on the above, further, the first screen support plate 210 may be provided with a receiving sink, and at least a portion of the avoidance structure is received in the receiving sink in the folded state, thereby preventing the adverse effect on the maximum relative rotation angle between the first screen support plate 210 and the first housing seat 310 due to the aforementioned avoidance structure provided on the first housing seat 310.
Specifically, the position, width, depth, and other parameters of the accommodating sink may be flexibly determined according to the actual parameters of the avoidance structure, which is not limited herein. More specifically, the second housing seat 320 may also be provided with a corresponding avoiding structure, and the second screen support plate 220 is correspondingly provided with a receiving slot, so as to improve symmetry of the folding mechanism and further improve overall performance of the folding mechanism.
In order to improve the compactness of the whole folding mechanism, as shown in fig. 3, the base 410 may be provided with a receiving slot 411, in which a first rotating portion 412 is disposed in the receiving slot 411, and by accommodating at least a portion of the second rotating portion 302 of the first housing seat 310 and at least a portion of the second rotating portion 302 of the second housing seat 320 in the manner of receiving and receiving the slot 411, the space occupied by the folding mechanism in the thickness direction of the base 410 may be reduced, thereby reducing the thickness of the whole electronic device and improving the overall product performance. It should be noted that, the thickness direction of the base 410 may be specifically a direction perpendicular to the direction a in fig. 1 and the direction B in fig. 9.
Specifically, the plurality of first rotating parts 412 may be disposed in one receiving groove 411 by enlarging the size of the receiving groove 411, and in another embodiment of the present application, in order to improve the coupling stability between the first and second housing seats 310 and 320 and the base 410, the first and second housing seats 310 and 320 are prevented from interfering with each other, and the receiving groove 411 may be disposed in plurality corresponding to the number of the first rotating parts 412. Of course, in order to ensure that at least a portion of the second rotating portion 302 received in the receiving slot 411 is normally relatively engaged with the first rotating portion 412, the specific structures of the first rotating portion 412 and the second rotating portion 302 may be adapted to the parameters such as the structure and the size of the receiving slot 411 during the design and the processing.
Further, in order to maximize the reliability of the rotational engagement relationship between the first rotating portion 412 and the second rotating portion 302 located in the receiving slot 411, alternatively, as shown in fig. 2 and 3, one of the first rotating portion 412 and the second rotating portion 302 includes a slider, the other one is provided with a slide groove, the slide groove is slidably engaged with the slider, the engagement area between the slide groove and the slider is relatively large, and the space in the receiving slot 411 can be maximally utilized. Of course, the sliding groove and the sliding block are both arc-shaped structures, so that the first housing seat 310 and the second housing seat 320 can both form a running fit relationship by means of the sliding fit sliding groove and the sliding block.
In order to further improve the stability of the rotation fit relationship between the first housing seat 310 and the second housing seat 320 and the base 410, as shown in fig. 3, the opposite sides of the accommodating slot 411 are provided with the first rotation portions 412, and correspondingly, the opposite sides of the first housing seat 310 and the second housing seat 320 are provided with the second rotation portions 302, and taking the first housing seat 310 as an example, in the case that the two second rotation portions 302 on the opposite sides are in one-to-one correspondence with the two first rotation portions 412 in one accommodating slot 411, the rotation of the first housing seat 310 relative to the base 410 can be further prevented from deviating from the rotation axis thereof, so that the stability of the rotation fit relationship between the first housing seat 310 and the base 410 is improved. Correspondingly, in the case of the above-mentioned technical solution, the rotation fit relationship between the second housing seat 320 and the base 410 is relatively more stable.
In the case where the first rotating portion 412 is disposed in the receiving slot 411, in order to ensure a good rotation-fit relationship between the first rotating portion 412 and the second rotating portion 302 while minimizing the width of the base 410 (i.e., the dimension of the base 410 in the direction B of fig. 9), alternatively, a plurality of first rotating portions 412 may be disposed at intervals or offset in the rotation axis direction of the second rotating portion 302. That is, the plurality of first rotating portions 412 may be distributed along the rotation axis direction of the second rotating portion 302 with a predetermined size of space between any adjacent two of the first rotating portions 412. Alternatively, in the case where the plurality of first rotating portions 412 are distributed along the rotation axis direction of the second rotating portion 302, the plurality of first rotating portions 412 may be grouped in pairs, and two first rotating portions 412 in any group may be disposed adjacent to each other in the rotation axis direction of the second rotating portion 302, that is, there is no space between two first rotating portions 412 in a group in the rotation axis direction of the second rotating portion 302.
Alternatively, the first screen support plate 210 may be rotatably coupled to the first housing 110 in a bracket structure, and as described above, the first housing seat 310 is fixedly coupled to the first housing 110, in which case the first screen support plate 210 may be enabled to form a rotational fit relationship with the first housing seat 310. In order to facilitate installation, as shown in fig. 3, the folding mechanism may include a rotating assembly, where the first screen support plate 210 may be rotatably connected to the first housing seat 310 through a plurality of rotating assemblies, and under the action of the plurality of rotating assemblies, on one hand, the stability of the running fit between the first screen support plate 210 and the first housing seat 310 may be improved, and on the other hand, the optional type of structure of the rotating assembly may be further enlarged, so as to reduce the design and processing difficulty.
As shown in fig. 3, the rotating assembly specifically includes a third rotating portion 510 and a fourth rotating portion 520, one of the third rotating portion 510 and the fourth rotating portion 520 is connected to the first housing base 310, and the other is connected to the first screen support plate 210. The third rotating part 510 includes the inserted block, and the fourth rotating part 520 is equipped with the slot, and inserted block and slot all are equipped with the arc mating surface, and inserted block and slot pass through arc mating surface normal running fit, can guarantee to have great normal running fit area between third rotating part 510 and the fourth rotating part 520, promote the reliability of rotation connection relation between the two. In addition, in the case of adopting the above-mentioned technical solution, by locating the rotation axes of the third rotation portion 510 and the fourth rotation portion 520 on the first screen support plate 210 or on the side of the first screen support plate 210 facing away from the first housing seat 310, the space between the first screen support plate 210 and the first housing seat 310 can be made relatively smaller while ensuring that the rotation assembly is located on the side of the first screen support plate 210 facing the first housing seat 310, so that the space occupied by the entire folding mechanism in the thickness direction of the base 410 can be further reduced.
Specifically, by adapting the shapes and the sizes of the insert block and the slot, the two can be ensured to form a rotation fit relation; the slot may have a structure with two open sides, so that the insert block may be mounted into the slot from one side of the slot, and the maximum relative rotation angle between the insert block and the slot may be limited by other structures such as the first housing seat 310 and the first housing 110. In addition, the relative positional relationship between the first screen support plate 210 and the first housing seat 310 in the rotation axis direction of the second rotation portion 302 may be limited by providing detachable limiting structures at two opposite ends of the first screen support plate 210 in the rotation axis direction of the second rotation portion 302, so as to prevent the relative movement of the first screen support plate 210 and the first housing seat in the aforementioned direction.
In another embodiment of the present application, as shown in fig. 2, the fourth rotating portion 520 includes a limiting member and a mating member, where the limiting member and the mating member enclose a slot, and the mating member is provided with an arc-shaped mating surface.

In the structure of the folding mechanism shown in fig. 5, the respective slots of the two sets of fourth rotating parts 520 provided at opposite ends of the first screen supporting plate 210 are provided outward, that is, the slots of the two sets of fourth rotating parts 520 are provided opposite to each other, in which case, as shown in fig. 3, the two sets of third rotating parts 510 engaged with the aforementioned two sets of fourth rotating parts 520 should be provided outside the two sets of fourth rotating parts 520, respectively.
Under the above technical solution, the limiting portions of the two fourth rotating portions 520 may be used to limit the at least two third rotating portions 510, so as to ensure that the third rotating portions 510 and the fourth rotating portions 520 can form a limiting fit relationship in the rotation axis direction of the second rotating portion 302, and ensure that the first screen support plate 210 and the first housing base 310 form a stable fit relationship in the rotation axis direction of the second rotating portion 302.
