Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

In order to facilitate understanding of the bending support component 03 provided in the embodiment of the present application, an application scenario thereof will be described below.

The bending support component provided by the embodiment of the application can be applied to folding electronic equipment, and the folding electronic equipment is particularly electronic equipment capable of changing the form of the folding electronic equipment in a folding, rotating and other modes; under different use requirement conditions, the user can fold and unfold the folding type electronic equipment to meet different requirements of the user.

For example, when a user needs to carry the foldable electronic device with him, he can fold it, so as to promote portability; when a user is using the folding electronic device, the folding electronic device can be unfolded to provide a larger display area and operation area, thereby improving the convenience of use.

In practical applications, the types of foldable electronic devices can be divided into various types, such as a folder-type mobile phone, a folder-type tablet computer, a notebook computer, a folder-type electronic book, and the like. Depending on the direction of folding, the folding electronic device may also include an inside fold and an outside fold.

Fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present application. Taking a folding mobile phone as an example, as shown in fig. 1, the folding mobile phone may include a first middle frame 01, a second middle frame 02, a bending support assembly 03 connecting the first middle frame 01 and the second middle frame 02, a display panel 04, and a middle casing 05, where under the action of the bending support assembly 03, the first middle frame 01 and the second middle frame 02 can open and close relatively, so as to realize a folding function.

The display panel 04 is disposed on the surfaces of the first and second middle frames 01 and 02, and is connected to the first and second middle frames 01 and 02, respectively. The display panel 04 may be a flexible display panel, such as an OLED flexible display panel.

When the folding mobile phone is unfolded, the display panel 04 can provide a larger display area and operation area, thereby improving usability. For the mobile phone of the inward folding type, after the folding type mobile phone is folded, the display panel 04 can be folded between the first middle frame 01, the second middle frame 02 and the bending support component 03, so that a good protection effect is provided for the display panel 04, the display panel 04 is prevented from being damaged under the action of external force, and therefore the safety performance of the folding type mobile phone is improved. For the out-folding mobile phone, when the folding mobile phone is folded, the display panel 04 is located at the outer sides of the first middle frame 01 and the second middle frame 02. Whether it is an inward folding mobile phone or an outward folding mobile phone, the mobile phone is easier to carry after folding.

The surface that the support piece of buckling supporting component 03 kept away from display panel 04 is used for supporting middle part casing 05, and middle part casing 05 can shelter from the support piece of buckling, on the one hand, is favorable to improving folding electronic equipment's aesthetic property, on the other hand, is favorable to preventing impurity such as dust from bringing the damage to the support piece of buckling, is favorable to improving the life of the support piece of buckling.

The application of the bending support assembly 03 in other foldable electronic devices is similar to that in a foldable mobile phone, and will not be described here. The specific structure of the bending support assembly 03 according to the embodiment of the present application will be described in detail.

Fig. 2 is a schematic structural view of a bending support assembly according to an embodiment of the present application, and fig. 3 is a schematic structural view of a bending support assembly according to an embodiment of the present application. As shown in fig. 2 and 3, the bending support assembly includes: a support plate 1 and two bending support members 2. The support plate 1 has a support surface 1A, and the support surface 1A is used for supporting a display panel of the folding electronic device. The two bending support combined pieces 2 are located on a first surface 1B of the support plate 1 opposite to the support surface 1A, and are respectively arranged along two opposite side edges of the support plate 1, namely, the two bending support combined pieces 2 are located on two opposite sides of the support plate 1, and two ends of the bending support combined pieces 2 are respectively connected with two middle frames of the folding electronic equipment.

For one bending support 2, n supports 21 and m elastic members 22 may be included, m and n being positive integers and m being smaller than n. The n supporting members 21 and the m elastic members 22 are alternately arranged in sequence along the side edges of the supporting plate 1, and the elastic members 22 are connected with the supporting members 21 adjacent thereto.

In some examples, the number m of elastic members 22 may be greater than or equal to 2 and less than or equal to 5, such as m being 2, m being 4, m being 5, etc. The number n of the supporting members 21 may be 1 greater than the number of the elastic members 22, i.e., n=m+1, and the number of the supporting members 21 and the elastic members 22 may be designed according to the actual product requirements, without any limitation.

Compared with the hinge mechanism in the related art, the bending support assembly provided by the embodiment of the application has the advantages that the number of parts is small, the structure is relatively simple, and the reason can be quickly found out and quickly replaced or maintained when the bending support assembly is damaged, so that the cost of the folding electronic product is reduced, and the flexibility of the folding electronic product is improved.

Fig. 4 is a schematic structural diagram of a bending support assembly according to an embodiment of the present application. In some examples, as shown in fig. 4, the support 21 in the bending support 2 may include: a connection portion 211 and a support portion 212. The connecting portion 211 is connected with the first surface 1B of the support plate 1, the supporting portion 212 is located at one end of the connecting portion 211 away from the first surface 1B, and is connected with the connecting portion 211, and the surfaces of the supporting portions 212 of the two bending support assemblies 2 away from the connecting portion 211 are coplanar.

The surface that connecting portion 211 was kept away from to supporting portion 212 is used for supporting folding electronic equipment's middle part casing, and the middle part casing can shelter from the supporting component of buckling, on the one hand, is favorable to improving folding electronic equipment's aesthetic property, on the other hand, is favorable to preventing impurity such as dust from bringing the damage to the supporting component of buckling, is favorable to improving the life of the supporting component of buckling.

As an example, the middle case of the foldable electronic device may be a structure shown by a dotted line portion in fig. 1, and for example, the middle case may be a flat plate structure located between two middle frames, at a side of the hinge mechanism away from the display panel and connected to the hinge mechanism in the related art.

In some examples, the connection portion 211 and the support portion 212 may be integrally formed by injection molding, or may be connected by welding, hinging, or clamping, which is not limited herein.

Fig. 5 is a top view of a bending support assembly according to an embodiment of the present application. As shown in fig. 2 and 5, the connecting portion 211 is flush with the edge of the support plate 1, and the orthographic projection of the support portion 212 on the first surface 1B of the support plate 1 is at least partially located inside the connecting portion 211. The inner side of the connecting portion 211 is that the connecting portion 211 of one bending support assembly 2 of the two bending support assemblies 2 is close to one side of the connecting portion 211 of the other bending support assembly 2. In other words, as shown in fig. 6, in the width direction O of the support plate 1, the length L1 of the connection portion 211 is smaller than the length L2 of the support portion 212. By adopting the scheme, the length L2 of the supporting part 212 in the width direction O of the supporting plate 1 is increased, so that the contact area between the supporting part 212 and the middle shell of the folding electronic equipment is increased, and the overall stability of the folding electronic equipment is improved.

In some examples, as shown in connection with fig. 2 and 5, the orthographic projection of the elastic member 22 on the support surface 1A may be a circular arc triangle, wherein the circular arc triangle is an isosceles triangle with a vertex angle of an arc, and the bottom side of the circular arc triangle is flush with the edge of the support plate 1.

As an example, the base angle of the circular arc triangle may be 45 degrees or more and 80 degrees or less, such as 45 degrees, 60 degrees, 80 degrees, or the like. The shape of the circular triangle can be designed according to the actual product requirement, and is not limited in any way.

Alternatively, the front projection of the elastic member 22 on the support surface 1A may be isosceles trapezoid, wavy, or the like. The shape of the elastic member 22 is not limited in any way.

As shown in fig. 2 and 5, the front projection of the support member 21 on the first surface 1B coincides with the edge portion of the front projection of the elastic member 22 connected thereto on the support surface 1A, in other words, the side wall of the elastic member 22 is fitted to the side wall of the support member 21.

When the folding electronic equipment using the folding support component 03 is folded, on one hand, the elastic piece 22 can generate damping sense with certain strength, which is beneficial to improving the use experience of a user, and on the other hand, the elastic piece 22 can generate certain tensile force to the support piece 21, which is beneficial to reducing the strength of the support piece 21 when the folding electronic equipment is folded, thereby facilitating the folding.

In some examples, referring to fig. 2, the support plate 1 is a rectangular flat plate structure, and the elastic member 22 is located on the first surface 1B of the support plate 1 and is attached to the first surface 1B. Under such circumstances, the supporting surface 1A of the supporting plate 1 may contact with the back surface of the display panel of the folding electronic device, when the folding electronic device is folded, the elastic member 22 will transfer its elastic force to the supporting plate 1 and transfer the elastic force to the display panel 04 through the supporting surface 1A of the supporting plate 1, thereby being beneficial to reducing the stress concentration on the display panel 04 during folding, and reducing the crease brought to the display panel 04, and further, being beneficial to improving the satisfaction degree of the user to the product and improving the user experience.

In other examples, as shown in fig. 7 and 8, fig. 7 is a schematic partial structure of a bending support assembly according to an embodiment of the present application, and at least the elastic member 22 is omitted in fig. 7. The support plate 1 may have a through slot 1C, and fig. 8 is a schematic structural diagram of a bending support assembly according to an embodiment of the present application, where a portion of the elastic member 22 is located in the through slot 1C. The orthographic projection of the through groove 1C of the support plate 1 on the support surface 1A coincides with the orthographic projection of the elastic member 22 on the support surface 1A, in other words, the side wall of the elastic member 22 is attached to the inner wall of the through groove 1C. Moreover, the surface of the elastic member 22 near the support surface 1A is flush with the support surface 1A of the support plate 1.

In this case, both the supporting surface 1A of the supporting plate 1 and the surface of the elastic member 22 near the supporting surface 1A may be used to support the display panel 04 of the folding electronic device, wherein the back surface of the display panel 04 of the folding electronic device may be attached to the surface of the elastic member 22 near the supporting surface 1A. When folding electronic equipment is buckled, because the back of the display panel 04 is attached to the elastic piece 22, the elastic piece 22 can apply self elastic force to the display panel 04, so that stress concentration during buckling is reduced, dislocation caused by buckling to the display panel 04 is reduced, crease brought to the display panel 04 is weakened, satisfaction of a user to a product is improved, and user experience is improved. Moreover, when folding the folding electronic equipment from the folding state to the flattening state, the soft rubber is favorable for improving the flattening capacity of the display panel and reducing the dislocation of the folding screen film layer, thereby being favorable for weakening folds and improving the user experience.

Fig. 9 is a schematic structural diagram of a bending support assembly according to an embodiment of the present application. As shown in fig. 9, the height of the supporting member 21 is greater than the height of the elastic member 22. The height of the elastic member 22 refers to a distance D1 from the second surface 22A of the supporting surface 1A to the supporting surface 1A of the elastic member 22, and the height of the supporting member 21 refers to a distance D2 from the third surface 212A of the supporting member 212 to the supporting surface 1A of the supporting member 21.

By adopting the scheme, a certain space is reserved between the second surface 22A of the elastic piece 22 and the third surface 212A of the supporting part 212, so that when the folding electronic equipment is folded, the elastic piece 22 has a deformation space in the direction perpendicular to the supporting surface 1A, and the movement interference between the elastic piece 22 and the middle shell of the folding electronic equipment is prevented, thereby ensuring the normal folding and unfolding of the folding electronic equipment and improving the stability of the folding electronic equipment.

In some examples, both the support plate 1 and the support 21 may be made of a superelastic metal material, which may also be referred to as a superelastic metal alloy. The super-elastic metal material may include a super-elastic nickel-titanium alloy material, and the content of each component in the super-elastic nickel-titanium alloy material may be as follows: the nickel content can be 55.3-56.3%, the vanadium content can be 0.40-0.90%, the aluminum content can be 0.05-0.18%, and the rest is titanium and unavoidable impurities. For the super-elastic nickel-titanium alloy material, the content of each component can be set according to the actual product requirement, and is not limited herein.

The super-elastic metal material generally has higher elasticity and wear resistance, and the support plate 1 and the support piece 21 are made of the super-elastic metal material, so that the high-modulus support performance required by the folding electronic equipment can be ensured, the high elasticity can be ensured, and the multi-time bending fatigue resistance can be realized, thereby being beneficial to reducing the probability of bending the support component caused by excessive bending times, and further being beneficial to improving the stability and the service life of the folding electronic product during working.

In some examples, the elastic member 22 may be a superelastic silicone material. On the one hand, the super-elastic silica gel material can generate damping sense with certain strength, which is beneficial to improving the use experience of users, and on the other hand, the elastic piece 22 can generate certain tensile force to the supporting piece 21, which is beneficial to reducing the strength of the supporting piece when the folding electronic equipment is folded, thereby facilitating the folding.

In some examples, the bending support assembly 2 may be manufactured by an insert molding process, in which the support 21 is manufactured, and then the support 21 is placed at a designated position in a mold, and the elastic member 22 is injection molded by the mold, so that the support 21 and the elastic member 22 are integrally formed; finally, injection moulding is carried out between the two support elements 2 with a mould to obtain the support plate 1, finally obtaining the whole bending support assembly.

Alternatively, the support 21 and the support plate 1 may be injection molded integrally by a mold, and then the elastic member 22 may be injection molded by a mold at a designated position of the support 21 and the support plate 1 that have been molded. The manufacturing process of the bending support assembly is not limited in any way.

The connection manner of the bending support member 03 and the first middle frame 01 or the second middle frame 02 is not limited in any way.

In some examples, the foldable electronic device may further include a display panel 04, a back surface of the display panel 04 being opposite to the supporting surface 1A of the bending supporting assembly 03, the display panel 04 being connected to the first middle frame 01 and the second middle frame 02, respectively, wherein the back surface of the display panel 04 is an opposite surface to the display surface.

The display panel 04 may be attached to the supporting surface 1A of the bending supporting component 03, alternatively, the display panel 04 may be contacted to the supporting surface 1A of the bending supporting component 03, and attached to the surface of the elastic member 22 near the supporting surface 1A. The connection method between the display panel 04 and the bending support member 03 is not limited.

Fig. 10 is a schematic structural diagram of an electronic device according to an embodiment of the present application. As shown in fig. 10, when the electronic device is bent, the two ends of the bending support component 03 deform along the direction towards the display panel 04, and the portion of the display panel 04 connected with the bending support component 03 changes phase, so that the first middle frame 01 and the second middle frame 02 can be opened and closed relatively, and a folding function is realized.

When the folding electronic equipment is folded, the elastic piece 22 in the folding supporting component 03 can generate damping sense with certain strength, so that the use experience of a user is improved; a certain pulling force can be generated on the supporting member 21, which is beneficial to reducing the strength of the supporting member 21, thereby facilitating bending. Moreover, the elastic member 22 can directly transfer the elastic force of the elastic member to the display panel 04 or transfer the elastic force to the display panel 04 through the supporting surface 1A of the supporting plate 1, thereby being beneficial to reducing the stress concentration on the display panel 04 during bending, reducing the crease brought to the display panel 04, and improving the satisfaction degree of the user to the product and the user experience.

In some examples, referring to fig. 1, the foldable electronic device may further include a middle housing 05, and the middle housing 05 may be attached to the third surface 212A of the support portion 212 of the support 21 of the folding support assembly 2.
