The electronic device provided by the embodiment of the present application is described in detail with reference to fig. 1 to 13 through specific embodiments and application scenarios thereof.

According to the electronic device provided by the embodiment of the application, referring to fig. 1 to 7, the electronic device includes: the device comprises a first shell 1, a second shell 2, a rotating shaft mechanism, a flexible screen 3 and a transmission mechanism;

the flexible screen 3 is arranged on the first shell 1 and the second shell 2 and covers the rotating shaft mechanism, and the flexible screen 3 can be switched between a folded state and an unfolded state along with the relative movement of the first shell 1 and the second shell 2;

the transmission mechanism comprises two transmission parts which are symmetrically arranged relative to the rotating shaft mechanism, each transmission part comprises a connecting rod seat 8 and a fan-shaped connecting rod 7 movably connected with the connecting rod seat 8, each connecting rod seat 8 is respectively connected to the first shell 1 and the second shell 2, and the first shell 1 and the second shell 2 are respectively connected with the rotating shaft mechanism through the transmission parts;

under the condition that the electronic equipment is switched from the unfolding state to the folding state, the transmission mechanism drives the first shell 1 and the second shell 2 to synchronously move towards the direction close to each other relative to the rotating shaft mechanism;

under the condition that the electronic equipment is switched from the folded state to the unfolded state, the transmission mechanism drives the first shell 1 and the second shell 2 to synchronously move towards the directions away from each other relative to the rotating shaft mechanism.

The electronic equipment provided by the embodiment of the application is folding electronic equipment, for example.

Further, the electronic device is, for example, an inside-out folding type electronic device. Such as a fold-out smart phone or a fold-out tablet, etc.

In the embodiment provided by the application, a flexible screen traceless folding scheme is provided for a folding type electronic device. When the flexible screen 3 is folded or unfolded with the electronic device, the housings (i.e. the first housing 1 and the second housing 2) of the electronic device may be displaced synchronously, and the displacement may correspond to the folding angle of the flexible screen 3, so that the flexible screen 3 may be protected from compression or tensile stress.

Moreover, the transmission mechanism adopted in the scheme of the application can stably drive the shell of the electronic equipment to move along with the flexible screen 3 in a proper amount, and the matching relation is simple and the manufacturing cost is low.

According to the scheme provided by the embodiment of the application, the basic principle is as follows: through pivot mechanism with drive mechanism's participation and mutually supporting, realized that the user switches to the state of expanding by fold condition controlling electronic equipment, perhaps switch to fold condition by the state of expanding in-process can be right the regional (for example middle part region) of buckling on the flexible screen 3 carries out certain support transition. The first casing 1 and the second casing 2 of the electronic device can generate relative displacement in the retraction direction (i.e. approach to each other) along with the bending of the flexible screen 3, and similarly, the first casing 1 and the second casing 2 can also generate relative displacement in the expansion direction (i.e. separate from each other) along with the bending of the flexible screen 3, so as to avoid the flexible screen 3 from generating local stress, thereby effectively solving the problem that the flexible screen on the folding electronic device is easily damaged and generates creases when the folding electronic device is folded (e.g. when the folding electronic device is folded outwards).

According to the scheme provided by the embodiment of the application, the portability of the electronic equipment and the holding comfort of the user are well improved on the basis of meeting the visual experience requirements of the user.

The scheme provided by the embodiment of the application well solves the problem that the flexible screen of the folding electronic equipment is damaged or creased due to frequent stress in the repeated folding or unfolding process. The scheme provided by the embodiment of the application is beneficial to prolonging the service life of the flexible screen on the folding electronic equipment, thereby being beneficial to the development of the folding electronic equipment.

In some examples of the present application, referring to fig. 3, the flexible screen 3 comprises: a first display portion 31, a second display portion 32, and a bendable display portion 33 connected between the first display portion 31 and the second display portion 32;

the first display portion 31 is fixedly arranged on the first casing 1, the second display portion 32 is fixedly arranged on the second casing 2, and the bendable display portion 33 is arranged above the rotating shaft mechanism;

referring to fig. 12 and 13, when the flexible screen 3 is switched to the folded state, the bendable display 33 is in a bent state, and the rotating shaft mechanism is configured to support the bendable display 33.

In addition, referring to fig. 10 and 11, when the flexible screen 3 is switched to the unfolded state, the bendable display portion 33 thereon is correspondingly in an unfolded (or flattened) state, and at this time, the bendable display portion 33 is horizontally suspended above the rotating shaft mechanism.

In the embodiment provided by the present application, the static display area and the dynamic bending display area of the flexible screen 3 are separated. The static display area refers to the first display unit 31 and the second display unit 32. The dynamic bending display area is the bending display part 33.

The first display portion 31 and the second display portion 32 are not bent or bent when the electronic device is switched from the unfolded state to the folded state, and are respectively and fixedly supported on the first casing 1 and the second casing 2. The bendable display 33 may have two different states, which may be expressed as a flat state in the unfolded state of the electronic device, as shown in fig. 1, or a bent state in the folded state of the electronic device, as shown in fig. 2.

The rotating shaft mechanism and the transmission mechanism are arranged below the bendable display part 33.

Wherein, through the pivot mechanism can realize flexible screen 3 is switching to the in-process of fold condition by the expansion state, to wherein the bendable display part 33 supports. The two shells (namely the first shell 1 and the second shell 2) of the electronic device can be driven to move close to each other relative to the rotating shaft mechanism along with the bending of the bendable display part 33 through the transmission mechanism; of course, the transmission mechanism may also drive the two housings (i.e., the first housing 1 and the second housing 2) of the electronic device to move away from each other with the unfolding of the bendable display portion 33 relative to the rotation axis mechanism. This design can avoid well producing compression or tensile stress on the display part 33 of can buckling, and then can avoid producing the crease on the display part 33 of can buckling, also can not be right the display part 33 of can buckling causes the damage.

Referring to fig. 10 to 13, in the process of switching the electronic apparatus from the folded state to the unfolded state or from the unfolded state to the folded state, the length of the region of the bendable display 33 does not change. In order to avoid the problem that the bendable display part 33 may generate compression or tensile deformation when folded, in the embodiment of the present application, it is designed that the first casing 1 and the second casing 2 can be properly expanded in the process of unfolding the electronic device, and the first casing 1 and the second casing 2 can be properly contracted in the process of folding the electronic device, and the displacement amount generated between the two casings corresponds to the bending radian of the bendable display part 33, so as to ensure that the bendable display part 33 is not subjected to compression or tensile stress, and thus, the problems of crease or strain and the like cannot be generated.

Note that the sleeve 6 is stationary with respect to the first and

second shaft assemblies

4 and 5, and functions to support the first and

second shaft assemblies

4 and 5.

The first rotating shaft assembly 4 is matched with the transmission mechanism to drive the first shell 1 to generate sliding motion, and similarly, the second rotating shaft assembly 5 is matched with the transmission mechanism to drive the second shell 2 to generate sliding motion. Like this, the display 33 that can buckle is at crooked or when flattening the corresponding position in display 33 below can buckle, first casing 1 with second casing 2 can for pivot mechanism produces synchronous motion, can be used to avoid the screen damage or the crease problem that display 33 can buckle because of frequently receiving compression or tensile stress leads to.
