Detailed Description

The following are preferred embodiments of the present application, and it should be noted that modifications and variations can be made by those skilled in the art without departing from the principle of the present application, and these modifications and variations are also considered as the protection scope of the present application.

Referring to fig. 1-8 together, the electronic device 1 provided in this embodiment includes a folding device 10, two housing assemblies 20, and a flexible screen 30. The folding device 10 includes a base 11 and a supporting component 12 disposed on one side of the base 11, and a portion of the supporting component 12 can rotate relative to the base 11. Two housing assemblies 20 are provided on opposite sides of the base 11, one housing assembly 20 being slidably connected to one end of the support assembly 12 and the other housing assembly 20 being slidably connected to the other end of the support assembly 12. The flexible screen 30 is fixed to the two housing components 20 and abuts against the support component 12.

The electronic device 1 provided in this embodiment includes, but is not limited to, mobile terminals such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a Personal computer (Personal Computer, PC), a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a Portable media player (Portable MEDIA PLAYER, PMP), a navigation device, a wearable device, a smart bracelet, a pedometer, and a stationary terminal such as a digital TV, a desktop computer, and the like. The present embodiment is not limited in type to the electronic apparatus 1, and will be described only schematically with a mobile phone.

The folding device 10 is mainly used for realizing the folding function of the electronic equipment 1 so as to drive the shell assembly 20 to move, and further drive the flexible screen 30 to unfold or fold. Alternatively, the electronic apparatus 1 includes two folding devices 10 arranged at intervals in the width direction, each folding device 10 including a base 11 and a supporting member 12, the base 11 being a basic component in the folding device 10 mainly for mounting various components in the folding device 10, the base 11 generally having a top surface, a bottom surface, and side surfaces, the top surface being closer to the flexible screen 30 than the bottom surface. The support assembly 12 may be provided on the top surface of the base 11. The support assembly 12 is used for supporting the flexible screen 30, that is, the flexible screen 30 is abutted against the support assembly 12, and the support assembly 12 can rotate relative to the base 11 while supporting the flexible screen 30, so as to control and restrict the folded shape of the flexible screen 30.

The housing assembly 20 is mainly used for installing and carrying various components, for example, the folding device 10 can be installed on the housing assembly 20, so that the movement track of the housing assembly 20 is controlled by using the folding device 10. In other words, the housing assembly 20 may likewise in turn control the movement of the folding device 10. Functional modules such as cameras, batteries, PCB assemblies, speakers, handsets, keys, etc. may also be provided within the housing assembly 20. And a flexible screen 30 may be further provided on the housing assembly 20 so that a movement trace of the flexible screen 30 is controlled by the housing assembly 20. In other words, the flexible screen 30 may likewise in turn control the movement of the housing assembly 20. In some embodiments, the surface of the housing assembly 20 may also act as an appearance surface, and thus the surface of the housing assembly 20 may be designed accordingly to provide the housing assembly 20 with a unique appearance effect. The present embodiment is not limited to the shape, material, structure, and other parameters of the housing assembly 20, as long as the functions of installation and protection can be achieved. For example, the housing assembly 20 may be made of all metal, all plastic, or some metal and some plastic.

Two housing assemblies 20 are located on opposite sides of the base 11, e.g., one housing assembly 20 is located on one side of the base 11 and the other housing assembly 20 is located on the other side of the base 11. This embodiment allows each housing assembly 20 to be slidably coupled to the support assembly 12, such as one housing assembly 20 slidably coupled to one end of the support assembly 12 and another housing assembly 20 slidably coupled to the other end of the support assembly 12. In other words, both housing assemblies 20 are slidable relative to the support assembly 12.

The flexible screen 30 is a member having a certain flexibility, and the flexible screen 30 can be bent to a certain extent as compared to a rigid member. For example, the flexible screen 30 includes, but is not limited to, flexible display screens, flexible touch display screens, and other flexible components having corresponding functions, or flexible components to which a flexible support plate is fixedly attached, such as flexible display screens attached with flexible steel plates, flexible touch screens, and the like. The flexible screen 30 is disposed on the same side of the two housing assemblies 20 as the folding device 10, and opposite ends of the flexible screen 30 are respectively fixed to the two housing assemblies 20. For example, one end of the flexible screen 30 may be adhered to one housing component 20 by an adhesive such as double sided tape, the other end of the flexible screen 30 may be adhered to the other housing component 20 by an adhesive such as double sided tape, and the flexible screen 30 may be folded or flattened with the housing component 20. In particular, the flexible screen 30 has a inflection region and non-inflection regions disposed on opposite sides of the inflection region. Wherein the bending area is arranged corresponding to the folding device 10, the non-bending area is correspondingly stuck on the two shell components 20, and the flexible screen 30 of the bending area is propped against the supporting component 12 of the folding device 10. Only the flexible screen 30 located in the bending area of the electronic device 1 will bend under the driving of the folding device 10 during the movement process, and fold and unfold along with the movement of the electronic device 1. The flexible screen 30 in the non-bending region is adhered to the two housing components 20, so that the two housing components 20 only rotate and/or move relatively, and the shape of the flexible screen is not changed. The flexible screen 30 in the non-bending region will not bend even if the two housing components 20 move. Thus, only the bending zone of the flexible screen 30 will typically be creased after a number of bends.

The electronic device 1 has two different states, an unfolded state and a folded state, during folding and unfolding. The unfolded state refers to the state that the two housing components 20 are completely unfolded from each other, and can be understood as the state that the flexible screen 30 is unfolded, or the state that the display surface of the flexible screen 30 is flat, as shown in fig. 1-4. In other words, the unfolded state is the limit state of the electronic device 1 during the unfolding process. As shown in fig. 6-7, the folded state refers to a state in which the two housing components 20 are completely folded with each other, and may also be understood as a state in which the flexible screen 30 is folded and two portions of the flexible screen 30 are disposed opposite to each other, or the display surface of the flexible screen 30 is folded. In other words, the folded state is the limit state of the electronic device 1 during the folding process. When the electronic device 1 is folded, the two housing assemblies 20 are folded over each other, and the two ends of the flexible screen 30 are folded over each other.

Alternatively, the folded state in this embodiment may be an outwardly folded state or an inwardly folded state. The two opposite display surfaces of the flexible screen 30 are disposed opposite each other when the folded state is the folded-out state, and the two opposite display surfaces of the flexible screen 30 are disposed opposite each other when the folded state is the folded-in state.

In the related art, the flexible screen 30 slides relative to the housing 21 during the bending process, so that the gap between the flexible screen 30 and the edge of the housing 21 is increased, thereby not only affecting the beauty, but also facilitating dust accumulation, impurities and the like. Dust may also cause the flexible screen 30 to resist movement over time. And components of the housing assembly 20, such as the camera head, also need to move relative to the housing 21 as the flexible screen 30 moves relative to the housing assembly 20 to ensure relative rest between the camera head and the flexible screen 30.

The electronic apparatus 1 according to the present embodiment is provided by fixing the flexible screen 30 to the housing assembly 20 while the housing assembly 20 is slidably connected to the support assembly 12. In other words, the flexible screen 30 is fixedly connected to the housing assembly 20, so that the flexible screen 30 and the housing assembly 20 cannot slide relatively, the flexible screen 30 and the housing assembly 20 can only move synchronously, and the housing assembly 20 and the support assembly 12 can slide relatively. Therefore, the sliding of the flexible screen 30 relative to the shell assembly 20 in the related art is converted into the sliding of the shell assembly 20 relative to the support assembly 12, and the problem of epidemic sliding of the flexible screen 30 and the shell assembly 20 in the related art is solved, so that the gap between the flexible screen 30 and the edge of the shell assembly 20 is kept unchanged, the appearance performance of the electronic equipment 1 is improved, and dust entering the gap can be prevented from influencing the sliding of the flexible screen 30. Furthermore, the flexible screen 30 is fixed to the housing assembly 20, so that the relative position between the components of the housing assembly 20, such as the camera, and the flexible screen 30 is prevented from being changed, thereby affecting the matching effect of the components of the housing assembly 20 and the flexible screen 30.

Referring again to fig. 3, in the present embodiment, the folding device 10 further includes two first decoration pieces 51 disposed on a side of the base 11 facing away from the flexible screen 30 and rotatably connected to the base 11, and each first decoration piece 51 is slidably connected to the housing assembly 20.

The folding device 10 may further include two first decorative pieces 51 in addition to the above components, where the two first decorative pieces 51 are disposed on a side of the base 11 facing away from the flexible screen 30 and are disposed at intervals, and the first decorative pieces 51 are used for shielding a bottom surface of the base 11, so that the first decorative pieces 51 and the housing assembly 20 together serve as an appearance surface of a back side of the electronic device 1. And each first trim piece 51 rotates the connection base 11 and the slider 22 to connect the slider 22 in the housing assembly 20. When the electronic device 1 is folded, the housing 21 and the sliding member 22 in the housing assembly 20 rotate relative to the base 11, the sliding member 22 drives the first decoration member 51 to synchronously rotate relative to the base 11, and the sliding member 22 can slide relative to the second supporting member 122 and the rotating member 14, so that the sliding member 22 can also slide relative to the first decoration member 51 to avoid interference during movement. By controlling the movement of the first decorative member 51 by the slider 22, the thickness of the electronic apparatus 1 can be reduced when the electronic apparatus 1 is in the folded state, and miniaturization of the electronic apparatus 1 can be achieved.

Alternatively, the first decoration 51 and the base 11 may be cooperatively connected with the circular arc groove through a circular arc rail for the purpose of relative rotation. The first decoration 51 and the sliding piece 22 can be matched and connected with the third sliding groove through the third sliding block to achieve the purpose of relative sliding.

Optionally, a second decoration 52 may be further disposed between the two first decoration 51, and the second decoration 52 is utilized to further cover the bottom surface of the base 11, and the base 11 is disposed on the second decoration 52, so that neither the second decoration 52 nor the base 11 will move when the electronic device 1 moves. The first decoration 51 is provided with a escape groove at a side close to the second decoration 52, so that the first decoration 51 escapes from the second decoration 52 when rotating relative to the base 11.

Referring to fig. 5 and 8 again, in the present embodiment, the electronic device 1 further includes two first elastic members 41, wherein opposite ends of one first elastic member 41 respectively support one end of the supporting component 12 and one housing component 20, and opposite ends of the other first elastic member 41 respectively support the other end of the supporting component 12 and the other housing component 20. Wherein, the first elastic member 41 is in a compressed state and the compression amount of the first elastic member 41 is the same when the electronic device 1 is in the unfolded state or the folded state.

The electronic device 1 may further comprise, in addition to the above-mentioned components, first elastic members 41, the opposite segment of each first elastic member 41 respectively abutting the support assembly 12 and the housing assembly 20. For example, opposite ends of one first elastic member 41 respectively abut against one end of the supporting component 12 and one housing component 20, and opposite ends of the other first elastic member 41 respectively abut against the other end of the supporting component 12 and the other housing component 20. This will drive the first elastic member 41 to compress or stretch when the electronic device 1 moves, i.e. the housing assembly 20 and the supporting assembly 12 slide relatively. In the present embodiment, first, the first elastic member 41 is compressed when the electronic device 1 is in the unfolded state or the folded state. In other words, the first elastic member 41 is already in a compressed state when the electronic device 1 is in the expanded state, and the first elastic member 41 is still in a compressed state when the electronic device 1 is in the folded state. It may also be understood that, no matter how the electronic device 1 moves the first elastic member 41, the first elastic member 41 in a compressed state may give the housing assembly 20 an elastic force, so as to increase the driving force for sliding the housing assembly 20 relative to the support assembly 12, and push the housing assembly 20 to push the housing assembly 20 outward relative to the support assembly 12 under the action of the first elastic member 41, so as to further increase the sliding effect of the housing assembly 20, and in particular, when the electronic device 1 is in the folded state to the unfolded state, the elastic force of the first elastic member 41 may push the housing assembly 20 to slide relative to the support assembly 12, so as to flatten the flexible screen 30, and the electronic device 1 is in the completely flattened unfolded state. And the two first elastic members 41 in a compressed state may also apply a tensile force to both ends of the flexible screen 30, thereby straightening the flexible screen 30 and relieving folds of the flexible screen 30.

In addition, the first elastic member 41 has a first compression amount when the electronic device 1 is in the unfolded state, and the first elastic member 41 has a second compression amount when the electronic device 1 is in the folded state, so that the compression amount of the first elastic member 41 is the same when the electronic device 1 is in the unfolded state or the folded state, that is, the first compression amount is equal to the second compression amount. In other words, when the electronic device 1 is in the unfolded state to the folded state and when the electronic device 1 is in the folded state to the unfolded state, the first elastic member 41 returns to the original position, so that the compression amount of the first elastic member 41 is the same, thereby reducing the stroke of the first elastic member 41 and the housing assembly 20 and improving the reliability of the electronic device 1.

In this embodiment, the electronic device 1 may further include a critical state in addition to the unfolded state and the folded state, and it is known from the above that the compression amount of the first elastic member 41 is the same when the electronic device 1 is in the unfolded state or the folded state, but since the flexible screen 30 slides synchronously with the housing assembly 20 relative to the support assembly 12 when the electronic device 1 moves, the housing assembly 20 can be controlled to slide relatively to the support assembly 12 near the base 11 and slide relatively far from the base 11. Or slide away from the base 11 before sliding closer to the base 11. The state of the housing assembly 20 when the direction of movement is changed may be referred to as a critical state. When the electronic device 1 is changed from the unfolded state to the critical state, the housing assembly 20 slides relative to the supporting assembly 12 in a direction approaching the base 11, in other words, the first elastic member 41 is compressed first. When the electronic device 1 changes from the critical state to the folded state, the housing assembly 20 slides relative to the supporting assembly 12 in a direction away from the base 11, in other words, the first elastic member 41 is pulled back, so that the compression amount of the first elastic member 41 is the same. When the electronic device 1 is changed from the folded state to the critical state, the housing assembly 20 slides relative to the supporting assembly 12 in a direction approaching the base 11, in other words, the first elastic member 41 is compressed first. When the electronic device 1 changes from the critical state to the expanded state, the housing assembly 20 slides relative to the supporting assembly 12 in a direction away from the base 11, in other words, the first elastic member 41 is stretched back, so that the compression amount of the first elastic member 41 is the same.

The present embodiment can realize that the compression amount of the first elastic member 41 is the same when the electronic device 1 is in the unfolded state or the folded state through the above control, so that the stroke of the first elastic member 41 and the housing assembly 20 is reduced, and the reliability of the electronic device 1 is improved.

Optionally, the stroke of the first elastic member 41 is 0.1mm-0.3mm, so that the electronic device 1 cannot complete due to too small stroke of the first elastic member 41, and the housing assembly 20 and the base 11 have larger clearance due to too large stroke of the first elastic member 41, resulting in larger drop reliability. Further alternatively, the stroke of the first elastic member 41 is 0.1mm to 0.15mm. Specifically, the stroke of the first elastic member 41 is 0.13mm.

Referring to fig. 5 and fig. 8-10 together, in the present embodiment, each housing assembly 20 includes a housing 21 fixed to the flexible screen 30 and a sliding member 22 fixed to the housing 21, the sliding member 22 has a first groove 220, the supporting assembly 12 includes a first supporting member 121 fixed to the base 11, and two second supporting members 122 disposed on opposite sides of the first supporting member 121, the two second supporting members 122 can rotate relative to the first supporting member 121, each second supporting member 122 is slidably connected to one sliding member 22, the second supporting member 122 has a second groove 1220, the first groove 220 and the second groove 1220 cooperate together to form a receiving groove 23 for receiving the first elastic member 41, opposite ends of the first elastic member 41 respectively abut against a first groove wall 221 of the first groove 220 and a second groove wall 1221 of the second groove 1220, and the first groove wall 221 is far away from the base 11 compared with the second groove wall 1221.

The housing assembly 20 includes a housing 21 and a slider 22, wherein the flexible screen 30 is fixed to the housing 21, and the slider 22 is fixed to the housing 21. Alternatively, the housing 21 and the slider 22 may be integrally formed or may be separately formed, and this embodiment is schematically illustrated with the housing 21 and the slider 22 being separately formed. Specifically, the housing 21 and the slider 22 may be detachably connected by screws. The slider 22 has a first groove 220 on a side thereof adjacent to the flexible screen 30, wherein the first groove 220 has only one first groove wall 221 in an arrangement direction of the two housings 21.

The support assembly 12 includes a plurality of support members, a first support member 121 and a second support member 122, wherein the first support member 121 is fixed to the base 11, such that the first support member 121 remains stationary with the base 11 when the electronic device 1 moves. Two second supporting members 122 are disposed on opposite sides of the first supporting member 121, for example, one second supporting member 122 is disposed on one side of the first supporting member 121, and the other second supporting member 122 is disposed on the other side of the first supporting member 121. The two second support members 122 may be directly or indirectly rotatably connected to the first support member 121, thereby enabling the two second support members 122 to rotate relative to the first support member 121.

Optionally, the support assembly 12 may further include two third support members 123, each third support member 123 being disposed between the first support member 121 and the second support member 122, the third support member 123 being rotatably connected to the first support member 121 and the second support member 122 being rotatably connected to the same side of the third support member 123. The support assemblies 12 are thus the second support 122, the third support 123, the first support 121, the third support 123, and the second support 122 in this order along the arrangement direction of the two housing assemblies 20. The flexible screen 30 is folded out into a predetermined shape by the movement locus of 5 supports when the electronic apparatus 1 is folded out.

Further alternatively, the two adjacent supporting pieces are matched with the circular arc grooves through circular arc rails so as to realize rotary connection. For example, the first supporting member 121 and the third supporting member 123, and the third supporting member 123 and the second supporting member 122 are all connected with the circular arc groove through circular arc rails in a matching manner.

Each second support 122 is slidably connected to one of the sliding members 22 through a first slider and a first chute, for example, the second support 122 on one side of the base 11 is slidably connected to the sliding member 22 on the same side of the second support 122, and the second support 122 on the other side of the base 11 is slidably connected to the sliding member 22 on the same side of the second support 122. The second support 122 has a second recess 1220 on the side facing away from the flexible screen 30, wherein the first recess 220 of the second recess 1220 has only one second groove wall 1221 in the direction of alignment of the two housings 21.

The second supporting member 122 is slidably connected with the sliding member 22, and the space of the first groove 220 and the space of the second groove 1220 can be overlapped, so that the first groove 220 and the second groove 1220 are cooperatively surrounded to form a new accommodating groove 23, and the accommodating space is used for accommodating the first elastic member 41. Meanwhile, since the first groove 220 and the second groove 1220 have only one groove wall, one end of the first elastic member 41 can abut against the first groove wall 221 of the first groove 220, and the other end can abut against the second groove wall 1221 of the second groove 1220. The elastic force of the first elastic member 41 can be transferred to the housing 21 and the second supporting member 122 through the first slot wall 221 and the second slot wall 1221, and the housing 21 and the second supporting member 122 can slide under the driving of the first elastic member 41.

In addition, the first groove wall 221 is further away from the base 11 than the second groove wall 1221, in other words, the first groove wall 221 is further outward and the second groove wall 1221 is further inward, so that the sliding member 22 slides along the direction approaching or separating from the base 11 relative to the second supporting member 122 in cooperation with the first elastic member 41.

Referring to fig. 9-12 together, in the present embodiment, the sliding member 22 and the second supporting member 122 are cooperatively connected with the limiting groove 222 through the limiting shaft 1223, the limiting shaft 1223 is disposed on one of the sliding member 22 and the second supporting member 122, and the limiting groove 222 is disposed on the other of the sliding member 22 and the second supporting member 122. The limiting groove 222 includes a first limiting end 2221 and a second limiting end 2222 disposed opposite to each other, where the first limiting end 2221 is closer to the base 11 than the second limiting end 2222. Wherein, the limiting shaft 1223 is close to the first limiting end 2221 when the electronic device 1 is in the unfolded state and the folded state, and the limiting shaft 1223 is close to the second limiting end 2222 when the electronic device 1 is in the critical state.

From the above, the electronic device 1 has the same compression amount of the first elastic member 41 when in the unfolded state and the folded state, and it is considered that the housing assembly 20 is not moved, and the housing assembly 20 is moved during the movement of the electronic device 1, and finally returns to the initial position. Therefore, the sliding track of the sliding member 22 relative to the second supporting member 122 can be controlled by providing the limiting shaft 1223 and the limiting groove 222 on the sliding member 22 and the second supporting member 122. The limiting shaft 1223 is disposed on one of the sliding member 22 and the second supporting member 122, and the limiting groove 222 is disposed on the other of the sliding member 22 and the second supporting member 122. Specifically, when the limiting shaft 1223 is disposed on the sliding member 22, the limiting groove 222 is disposed on the second supporting member 122, and when the limiting groove 222 is disposed on the sliding member 22, the limiting shaft 1223 is disposed on the second supporting member 122, and in this embodiment, only the limiting groove 222 is disposed on the sliding member 22 and the limiting shaft 1223 is disposed on the second supporting member 122 for schematic illustration. Specifically, the screw is detachably disposed on the second support 122, and a portion of the screw penetrating the second support 122 is a limiting shaft 1223. The sliding member 22 is provided with a limiting groove 222, and a limiting shaft 1223 is arranged in the groove.

When the sliding member 22 slides relative to the second supporting member 122, the limiting shaft 1223 slides in the limiting groove 222, and the limiting groove 222 includes two opposite ends, namely a first limiting end 2221 and a second limiting end 2222, wherein the first limiting end 2221 is closer to the base 11 than the second limiting end 2222, in other words, the first limiting end 2221 is disposed further inward, and the second limiting end 2222 is disposed further outward. The limiting shaft 1223 is close to the first limiting end 2221 when the electronic device 1 is in the unfolded state and the folded state, and the limiting shaft 1223 is close to the second limiting end 2222 when the electronic device 1 is in the critical state, and then the sliding member 22 performs a reverse movement with respect to the second supporting member 122. Therefore, the present embodiment can control the sliding track of the sliding member 22 relative to the second supporting member 122 by providing the limiting shaft 1223 and the limiting groove 222, thereby controlling the stroke of the first elastic member 41.

Referring to fig. 11-14, in the present embodiment, the base 11 includes a first sub-base 111 and a second sub-base 112 disposed along a direction perpendicular to the arrangement direction of the two housing components 20 and spaced apart from each other, and a rotating shaft 13 fixed between the first sub-base 111 and the second sub-base 112, the folding device 10 further includes a rotating member 14 sleeved on the rotating shaft 13, a mating member 15, and a second elastic member 16, the rotating member 14 is slidably connected to the housing components 20, the rotating member 14 is located on at least one side of the first sub-base 111, a side of the rotating member 14 facing away from the first sub-base 111 has a first cam surface 140, the mating member 15 is located on a side of the rotating member 14 facing the second sub-base 112, a side of the mating member 15 facing the rotating member 14 has a second cam surface 150, and opposite ends of the second elastic member 16 respectively abut against the mating member 15 and the second sub-base 112, and the second elastic member 16 are both in a compressed state when the electronic device 1 is in an expanded state or a folded state.

The base 11 of the present embodiment is not an integral component, but is formed by combining a plurality of sub-components, specifically, the base 11 includes a first sub-base 111 and a second sub-base 112 that are disposed at intervals, and the first sub-base 111 and the second sub-base 112 are arranged along a direction perpendicular to the arrangement direction of the two housing assemblies 20. In other words, the arrangement direction of the two housing assemblies 20 can be understood as the length direction of the electronic device 1, so that the arrangement direction of the first sub-base 111 and the second sub-base 112 is the width direction of the electronic device 1. A rotating shaft 13 is further disposed between the first sub-base 111 and the second sub-base 112, alternatively, the rotating shaft 13 may be integrally disposed with one of the sub-bases 11 and separately designed with the other sub-base 11, so as to facilitate assembly and disassembly, and facilitate sleeving of other components on the rotating shaft 13.

The folding device 10 may include a rotating member 14, a mating member 15, and a second elastic member 16 in addition to the above-described components. The rotating member 14 is located on at least one side of the first sub-base 111, i.e. the rotating member 14 may be located on one side of the first sub-base 111, or the rotating member 14 may be located on two opposite sides of the first sub-base 111, and the present embodiment is only schematically illustrated with the rotating member 14 located on two opposite sides of the first sub-base 111. The rotating member 14 is rotatable relative to the first sub-base 111. And the rotating member 14 is also slidably connected to the sliding member 22 in the housing assembly 20, that is, the rotating member 14 rotates relative to the first sub-base 111 while the sliding member 22 also slides relative to the rotating member 14. Optionally, the sliding member 22 is provided with a second sliding groove, and the end of the rotating member 14 may be understood as a second sliding block, and the second sliding block is disposed in the second sliding groove so as to enable the rotating member 14 to slide relative to the sliding member 22.

In addition, a surface of the rotating member 14 facing away from the first sub-base 111 is a first cam surface 140, and the first cam surface 140 may be understood as a surface formed by combining and splicing a plurality of peaks and valleys, so that the cross-sectional shape of the first cam surface 140 is a wave shape. The first cam surface 140 rotates as the rotating member 14 rotates. The first sub-base 111, the rotating member 14, the mating member 15, the second elastic member 16, and the second sub-base 112 are sequentially disposed along the direction from the first sub-base 111 to the second sub-base 112, and a second cam surface 150 is disposed on a side of the mating member 15, which is close to the rotating member 14, wherein the second cam surface 150 can be the same as the first cam surface 140, and the detailed description of this embodiment is omitted herein. The second elastic member 16 is in a compressed state when the electronic device 1 is in the extended state or the folded state, so the elastic force of the second elastic member 16 can make the second cam surface 150 of the mating member 15 always abut against the first cam surface 140 of the rotating member 14. When the electronic device 1 moves, the rotating member 14 rotates relative to the first sub-base 111 to rotate the first cam surface 140, and the rotating first cam surface 140 and the second cam surface 150 cooperate with each other to enable the matching member 15 to slide along the axial direction of the rotating shaft 13, so as to compress the second elastic member 16, and the elastic force of the second elastic member 16 enables the second cam surface 150 of the matching member 15 to further abut against the first cam surface 140 of the rotating member 14, so as to provide a damping force for the movement of the electronic device 1. In addition, the first sub-base 111, the rotating member 14, the mating member 15, the second elastic member 16, and the second sub-base 112 are arranged along the width direction of the electronic device 1, so that the folding device 10 can be narrower and thinner, and the space occupied by the folding device 10 for stacking mobile phones is smaller.

In this embodiment, when the electronic device 1 is in the unfolded state or the folded state, the peaks in the first cam surface 140 and the second cam surface 150 abut against the troughs, so as to realize the self-locking function of the electronic device 1, that is, the rotating member 14 does not freely rotate relative to the first sub-base 111, which is equivalent to the case assembly 20 not rotating at will, and the stability of the case assembly 20 in the unfolded state and the folded state is ensured. Therefore, the electronic device 1 of the present embodiment can realize self-locking in both the unfolded state and the folded state.

The electronic device 1 has a hovering state in addition to the above-mentioned state, where the hovering state refers to a state in which the housing assembly 20 can stay in place without falling back if an external force is removed from the housing assembly 20 during rotation, for example, a user releases his or her hand to hold the housing assembly 20. When the electronic device 1 is in a hovering state, the peaks of the first cam surface 140 abut the peaks of the second cam surface 150. The second elastic piece 16 can be further compressed when the wave crest is opposite to the wave crest, so that the elastic force of the second elastic piece 16 to the matching piece 15 is increased, the hovering function is realized, and the hovering range is larger, the hovering angle is larger, and the experience is better by adopting the mutual matching of various cam mechanisms with cam surfaces.

In this embodiment, the base 11 includes two rotating shafts 13 fixed between the first sub-base 111 and the second sub-base 112, the two rotating shafts 13 are disposed at intervals along the arrangement direction of the two housing components 20, each rotating shaft 13 is provided with one rotating member 14, one mating member 15, and one second elastic member 16, and the two mating members 15 of the two rotating shafts 13 are connected to each other.

In the present embodiment, two rotating shafts 13 may be disposed between the first sub-base 111 and the second sub-base 112, and the two rotating shafts 13 may be disposed at intervals along the length direction. Each rotating shaft 13 is sleeved with a rotating member 14, a matching member 15 and a second elastic member 16. In this way, more damping force can be provided on the premise of realizing the movement of the left side and the right side of the folding device 10, and the functions of self-locking and hovering are better realized.

Also, the present embodiment also connects the mating pieces 15 on each of the rotating shafts 13 together, in other words, connects the two mating pieces 15 of the two rotating shafts 13 to each other. Alternatively, the two matching pieces 15 are in an integral structure, and the two matching pieces 15 are sleeved on the two rotating shafts 13 at the same time and correspondingly provided with two second cam surfaces 150. When the rotating member 14 located at one side of the base 11 rotates, the first cam surface 140 and the second cam surface 150 cooperate with each other to drive the matching member 15 on the rotating shaft 13 to slide along the rotating shaft 13, and because the two matching members 15 are connected with each other, the matching member 15 on the other rotating shaft 13 slides synchronously, so that the second cam surface 150 cooperates with the first cam surface 140 to drive the rotating member 14 at the other side of the base 11 to rotate synchronously. Therefore, the synchronous rotation of the left side and the right side of the electronic equipment 1 can be realized on the premise of realizing hovering and self-locking by the design of the two matching pieces 15.

In this embodiment, the base 11 includes a first sub-base 111 and two second sub-bases 112 disposed on opposite sides of the first sub-base 111, a rotating shaft 13 is disposed between each second sub-base 112 and the first sub-base 111, the rotating member 14 is sleeved on the two rotating shafts 13 disposed on opposite sides of the first sub-base 111, and each rotating shaft 13 is further provided with a mating member 15 and a second elastic member 16.

The base 11 may include a first sub-base 111 and two second sub-bases 112, the two second sub-bases 112 are disposed on opposite sides of the first sub-base 111, and a rotation shaft 13 is disposed between the first sub-base 111 and the second sub-base 112 on each side of the first sub-base 111. In this embodiment, the rotating members 14 are located at two opposite sides of the first sub-base 111, so that the rotating members 14 can be sleeved on two rotating shafts 13 at two opposite sides of the first sub-base 111, and each rotating shaft 13 is further provided with a matching member 15 and a second elastic member 16, and the rotating members 14 at each side of the first sub-base 111, the matching member 15 and the second elastic member 16 can be mutually matched to provide more damping force, so that the self-locking and hovering functions can be better realized. Alternatively, the present embodiment may form four sets of cam mechanisms in the width direction, further increasing the damping force of the electronic apparatus 1.
