Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings of the embodiments of the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The folding mechanism and the electronic device provided by the embodiment of the application are described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1 to 12, the embodiment of the application discloses a folding supporting device and an electronic device, where the folding supporting device can be applied to the electronic device, so that the electronic device forms a folding electronic device. The electronic device may include a flexible screen 700, the flexible screen 700 being at least part of a display module of the electronic device. The flexible screen 700 may include a first portion and a second portion, the second portion being attached to one end of the first portion. Alternatively, the first portion may have only one end connected to the second portion, or both opposite ends of the first portion may have the second portion connected thereto. The flexible screen 700 can be supported and contained by the folding supporting device, and the flexible screen 700 can be switched between the unfolding state and the folding state along with the folding supporting device, so that the electronic equipment has a larger display area and better portability.
It should be noted that, in the case that the electronic device adopts the folding supporting device, the display module of the electronic device may include a whole flexible screen 700, and the flexible screen 700 is mounted on the folding supporting device; alternatively, the display module of the electronic device may also include a plurality of hard screens and a plurality of flexible screens 700. Taking the display module set as an example, the display module set comprises at least three flexible screens 700 and at least two hard screens, in this case, the number of the bases in the folding supporting device can be two, the two hard screens can be respectively supported on the two bases in a one-to-one correspondence manner, and one of the three flexible screens 700 is connected between the two adjacent hard screens, so that the whole display module set has folding and unfolding capabilities by means of the flexible screens 700; the other two flexible screens 700 are respectively connected to one side of the two hard screens, which is away from the other side, namely, the whole display module is sequentially provided with the flexible screen, the hard screen, the flexible screen, the hard screen and the flexible screen from one end to the other end, and the display module can also be matched with the folding supporting device disclosed by the embodiment of the application, and the electronic equipment is ensured to be switched between an unfolding state and a folding state. For convenience of description, the display module of the electronic device includes a whole flexible screen 700. In the case where the display module includes a single flexible screen 700, the different portions of the flexible screen 700 may be virtually divided into a first portion and a second portion, but in the flexible screen 700, the first portion and the second portion may not have a substantial limit or difference in physical structure.
As shown in fig. 1 and 2, the folding supporting device includes a base, a rotating shaft, and a connection seat 230. As mentioned above, the number of the bases may be plural, and in the folding supporting device disclosed in the embodiment of the present application, the number of the rotating shafts may also be plural, where the plural bases include the first base 110 and the second base 120, and the plural rotating shafts include the first rotating shaft 210 and the second rotating shaft 220. Under the condition that a plurality of rotating shafts are arranged between two adjacent bases, the distance between the two adjacent bases is relatively large, so that the bending degree of the flexible screen 700 can be reduced to a certain extent in the process that the flexible screen 700 in the display module is wound along with the folding of the folding supporting device, and the service life of the flexible screen 700 is prolonged.
Wherein the base is a component of the folding support device for positioning and supporting the flexible screen 700 of the electronic device, the flexible screen 700 may be supported on a screen support surface of the base. The region of the flexible screen 700 corresponding to the base is directly or indirectly connected to the base, so that the folding support device and the flexible screen 700 can normally perform folding and unfolding processes together. As described above, the plurality of bases include the first base 110 and the second base 120, and the structures and the dimensions of the first base 110 and the second base 120 may be different, or the structures of the first base 110 and the second base 120 may be the same, so as to reduce the spare parts and the installation difficulty of the two, and improve the overall appearance performance of the folding supporting device and the electronic device. The bases can be made of metal or plastic, the general shape of the bases can be rectangular, and the size of each base can be determined according to practical requirements, and the bases are not limited herein.
In order to ensure that the base can drive the flexible screen 700 to perform the folding and unfolding process normally, taking the first base 110 as an example, a first sliding member may be disposed on the first base 110, where an extending direction of the first sliding member is a direction perpendicular to an axial direction of the first rotating shaft 210 and parallel to a screen supporting surface of the first base 110 (the foregoing direction may be considered as a width direction of the first base 110). A side surface of the flexible screen 700 facing the first base 110 may also be provided with a second slider corresponding to the first slider, the first slider and the second slider being slidably fitted in the width direction of the first base 110. Also, the first slider and the second slider are also in a limit fit in a direction perpendicular to the axial direction of the first rotation shaft 210 and perpendicular to the screen supporting surface of the first base 110 (the aforementioned direction may be regarded as the thickness direction of the first base 110); meanwhile, the first slider and the second slider are also in a limit fit in the axial direction of the first rotation shaft 210 (the aforementioned direction may be regarded as the length direction of the first base 110). In this case, the portion of the flexible screen 700 that mates with the first base 110 can be in a reliable connection relationship with the first base 110, and the flexible screen 700 (the portion that mates with the first base 110) can be maintained in a substantially bonded or substantially bonded state with the first base 110 at all times by the mating relationship between the flexible screen 700 and the first base 110 when the first base 110 moves relative to the second base 120. Similarly, the assembly relationship between the portion of the flexible screen 700 corresponding to the second base 120 and the portion corresponding to the second base 120 may also be correspondingly arranged with reference to the first base 110.
In this embodiment, the electronic device formed by the folding support device is an everting electronic device, in this case, when the electronic device is in a folded state, the flexible screen 700 is located at the outer side, and the flexible screen 700 wraps the folding support device. The flexible screen 700 of the electronic device is bent to a relatively small extent, so that the service life of the flexible screen 700 can be prolonged; and, when the electronic device is in a folded state, gaps are not generated between different parts of the flexible screen 700, so that fine particles can be prevented from entering the gaps to damage the flexible screen 700.
In the case of the electronic device being an everted electronic device, the distance of the flexible screen 700 that the folding support device can carry in the unfolded state (i.e. the dimension of the portion of the flexible screen 700 that is supported on the folding support device in the width direction of the first base 110) is a first dimension, and the distance of the flexible screen 700 that the folding support device can carry in the folded state (i.e. the length of the shortest track when the particles move from one end to the other end of the portion of the flexible screen 700 that is supported on the folding support device) is a second dimension. Since the second dimension is larger than the first dimension, the design is required according to the structure of the folding supporting device, so as to ensure that the flexible screen 700 does not warp, partially arch, stretch, and the like.
Based on the above, in the embodiment of the present application, at least one of the first base 110 and the second base 120 is provided with a receiving cavity, which can receive the second portion of the flexible screen 700, that is, by making the second portion of the flexible screen 700 located at the end portion be received in the receiving cavity, the size of the portion of the flexible screen 700 supported on the folding supporting device is reduced, and thus, when the folding supporting device is in the unfolded state, a reliable supporting effect can be provided for the partial structure of the flexible screen 700. Specifically, the receiving cavity may be provided only on the first base 110, or the receiving cavities may be provided on both the first base 110 and the second base 120, so that the second portions of the opposite ends of the flexible screen 700 are respectively received by the receiving cavities on the respective first base 110 and the second base 120.
The first and second shafts 210 and 220 are rotation bases of the first and second bases 110 and 120, respectively, and the first and second shafts 210 and 220 are connected with the connection base 230. Alternatively, the first shaft 210 and the second shaft 220 may each form a rotation fit with the connection base 230, so as to ensure that the first base 110 and the second base 120 each have a capability of rotating relative to the connection base 230. Of course, the first rotating shaft 210 and the second rotating shaft 220 may be fixedly connected with the connecting seat 230, in this case, the first base 110 may be rotationally matched with the first rotating shaft 210, and the second base 120 may be rotationally matched with the second rotating shaft 220, which may also ensure that the first base 110 and the second base 120 both have the capability of rotating relative to the connecting seat 230. In addition, in the direction perpendicular to the axial direction of the first shaft 210, the first shaft 210 and the second shaft 220 are relatively fixed to the connection base 230, so that the distance between the first shaft 210 and the second shaft 220 in the direction perpendicular to the axial direction of the two is kept constant under the action of the connection base 230, and a stable rotation base is provided for the relative rotation of the first base 110 and the second base 120.
Specifically, two mounting holes may be provided on the connection base 230, and the first shaft 210 and the second shaft 220 may be respectively mounted in one mounting hole, and the first shaft 210 and the second shaft 220 may be respectively in a rotation fit relationship with the connection base 230 by using the two mounting holes. The first shaft 210 and the second shaft 220 may be cylindrical rod-shaped structures, so as to improve stability of the rotation fit relationship between the two shafts and the connection base 230.
The first base 110 is connected with the first rotating shaft 210, the second base 120 is connected with the second rotating shaft 220, and the matching relationship between the first base 110 and the first rotating shaft 210 and the matching relationship between the second base 120 and the second rotating shaft 220 can be determined according to the matching relationship between the first rotating shaft 210 and the second rotating shaft 220 and the connecting seat 230, so that the first base 110 can form a rotating matching relationship with the connecting seat 230 through the first rotating shaft 210, and the second base 120 can form a rotating matching relationship with the connecting seat 230 through the second rotating shaft 220, thereby ensuring the relative rotation capability between the first base 110 and the second base 120.
Specifically, the first base 110 and the first rotating shaft 210 may form a fixed connection relationship by bonding or welding; similarly, a fixed connection relationship may be formed between the second base 120 and the second shaft 220; alternatively, the first base 110 and the first shaft 210, and the second base 120 and the second shaft 220 may be in a rotationally fit relationship by sleeving.
In operation of the folding support device disclosed in the above embodiments, the flexible screen 700 may be mounted on the folding support device, and the electronic device may be formed as an eversion type electronic device. The folding support device has a first state and a second state, the folding support device being switchable between the first state and the second state. In the case that the folding supporting means is in the first state, the screen supporting surfaces of the first base 110 and the second base 120 are disposed coplanar with each other, that is, the first base 110 and the second base 120 are laid flat so that the folding supporting means is in the unfolded state. Meanwhile, in the first state, the receiving cavity is capable of receiving the second portion of the flexible screen 700 supported on the folding support device, that is, a portion of the structure of the flexible screen 700 may be received in the folding support device to reduce the size of the portion of the flexible screen 700 supported on the screen support surface of the folding support device.
In the case that the folding supporting device is in the second state, the screen supporting surfaces of the first base 110 and the second base 120 are disposed opposite to each other, that is, the first base 110 and the second base 120 are disposed in a stacked manner, and the flexible screen 700 is wrapped outside the first base 110 and the second base 120, the folding supporting device is in the folded state. Meanwhile, in order to ensure that the flexible screen 700 is not stretched along with the folding process of the folding support device during the switching of the folding support device from the first state to the second state, the second portion of the flexible screen 700 may be used to compensate for the size of the portion of the flexible screen 700 supported on the folding support device, so as to prevent the flexible screen 700 from being stretched while being folded along with the folding support device by increasing the size of the portion of the flexible screen 700 supported on the folding support device. Further, in the case where the folding support means is in the second state, at least a part of the second portion of the flexible screen 700 supported on the folding support means is supported on the folding support means.
The embodiment of the application discloses a folding support device and electronic equipment, folding support device can support and accomodate flexible screen 700, and flexible screen 700 includes first portion and connects the second portion at first portion tip. The folding supporting device comprises a first base 110, a second base 120, a first rotating shaft 210, a second rotating shaft 220 and a connecting seat 230, wherein at least one of the first base 110 and the second base 120 is provided with a containing cavity for containing a second part of the flexible screen 700, the first base 110 is rotationally connected with the connecting seat 230 through the first rotating shaft 210, and the second base 120 is rotationally connected with the connecting seat 230 through the second rotating shaft 220, so that the folding supporting device has unfolding and folding capabilities, and the folding supporting device can be switched between a first state and a second state.
In the case that the folding supporting means is in the first state, the screen supporting surfaces of the first base 110 and the second base 120 are coplanar, so that the folding supporting means is in the unfolded state, in this case, the accommodating cavity can accommodate the second portion of the flexible screen 700 supported on the folding supporting means, so that a part of the structure of the flexible screen 700 can be accommodated in the folding supporting means, and the flexible screen 700 is prevented from being partially arched or tilted. In the case where the folding support means is in the second state, the screen support surfaces of the first and second bases 110 and 120 are disposed opposite to each other, so that the folding support means is in the folded state, in which case at least a portion of the second portion of the flexible screen 700 supported on the folding support means is supported on the folding support means, thereby increasing the size of the portion of the flexible screen 700 supported on the folding support means, and preventing the flexible screen 700 from being damaged by being stretched during folding with the folding support means.
In summary, in the folding process of the folding supporting device disclosed in the embodiments of the present application, since the first base 110 and the second base 120 in the folding supporting device only generate relative rotation motions, the bending position and the bending angle of the portion of the flexible screen 700 corresponding to the portion between the first base 110 and the second base 120 remain constant, so that the service life of the flexible screen 700 can be improved.
As described above, the first base 110 and the second base 120 can be in a limit fit relationship with the flexible screen 700, so that the flexible screen 700 can always keep a fitting state with the first base 110 and the second base 120 during the process of switching the folding supporting device between the folded state and the unfolded state. In another embodiment of the present application, the first base 110 is provided with the above-described receiving cavity, that is, a portion of the flexible screen 700 may be received in the receiving cavity of the first base 110.
