Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.

The embodiment of the application provides a folding display terminal, which can be a product with a display interface, such as a mobile phone, a display, a tablet computer, a vehicle-mounted computer and the like. The embodiment of the present application does not specially limit the specific form of the folding display terminal.

In order to facilitate understanding of the foldable display terminal provided in the embodiment of the present application, a foldable display terminal of an existing type is described below with reference to fig. 1 as follows:

as shown in fig. 1, the folding display terminal 01 includes a flexible display screen 10. The flexible display screen 10 may be an Active Matrix Organic Light Emitting Diode (AMOLED) display screen.

The AMOLED display screen is a self-luminous display screen, and a Back Light Module (BLM) is not required. Therefore, when the substrate in the AMOLED display screen is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display screen can have a bendable characteristic.

In addition, as shown in fig. 1, the foldable display terminal 01 further includes a rotation mechanism 20, and the rotation mechanism 20 may be used to support the flexible display screen 10.

The rotating mechanism 20 includes a first structure 201, a second structure 202, and a rotating shaft 203 between the first structure 201 and the second structure 202.

The rotating shaft 203 is connected to the first and second

structural members

201 and 202. The first structure 201 and the second structure 202 are rotatable about the rotation shaft 203, respectively. The first structural member 201 and the second structural member 202 may be a housing or a middle frame structure of an electronic device.

The first structural member 201 and the second structural member 202 may be used to support the flexible display screen 10, so that the flexible display screen 10 is kept as flat as possible during use, and the non-display surface of the flexible display screen 10 is protected.

The embodiment of the present application does not limit the specific structure of the flexible display screen 10. The flexible display screen 10 may be divided into a first area, a second area and a third area, wherein the third area is located between the first area and the second area.

The first region of the flexible display 10 is fixed to the first structural member 201 by the glue layer 30, the second region is fixed to the second structural member 202 by the glue layer 30, and the third region is fixed to the rotation shaft 203 by the glue layer 30.

The glue layer 30 may be a thin film layer formed after glue is applied, and the embodiment of the present application is not limited to the specific form of the glue layer 30. In addition, other electronic components, such as a camera, an earphone, a button, a battery, and the like, may be disposed on the first structural member 201 and the second structural member 202, and the embodiment of the present application is not limited to the other electronic components disposed on the first structural member 201 and the second structural member 202.

The first structural member 201 and the second structural member 202 can rotate along the axis O-O of the rotating shaft 203, respectively, so as to fold or unfold the flexible display screen 10. As shown in fig. 2A, the flexible display screen 10 may be bent and flattened, wherein fig. 2A is a folding process of the flexible display screen 10 from 180 ° to 0 ° or a flattening process of the flexible display screen from 0 ° to 180 °.

As shown in fig. 2B, when the included angle α between the first structural member 201 and the second structural member 202 is 0 °, the flexible display screen 10 is in a folded state.

Alternatively, as shown in fig. 2C, when the included angle α between the first structural member 201 and the second structural member 202 increases to 180 °, the flexible display screen 10 is in the unfolded state.

It should be noted that the included angle α may have an error of 0 ° or 180 °, and the error range is, for example, ± 5 °, which all fall within the protection scope of the present application.

However, when the ambient temperature of the environment where the foldable display terminal is located is lower than the preset value, the material of the flexible display screen 10 may become brittle due to low temperature, and if the flexible display screen 10 is randomly deformed in a low-temperature environment, the reliability and the service life of the screen may be affected, or even the screen may be physically damaged.

The embodiment of the application can design a buckle assembly capable of being automatically locked at extremely low temperature, for example, -20 ℃, for a folding mobile phone product locked through a buckle in a folding form, and the buckle assembly is arranged on the first structural member 201 and the second structural member 202, and is locked at extremely low temperature, so that the first structural member 201 and the second structural member 202 cannot rotate, and the damage to the flexible display screen 10 caused by the expansion or folding of the mobile phone by a user at extremely low temperature is avoided.

Fig. 3 is a schematic structural diagram of a buckle assembly according to an embodiment of the present application. Fig. 5 is a schematic structural diagram of another buckle assembly provided in the embodiment of the present application. As shown in fig. 3 and 5, the clip assembly 40 includes: a catch 41 and a catch 42.

This buckle 41 includes: a first elastic member 4011, wherein a second elastic member 4012 is provided inside or outside the first elastic member 4011, and wherein the second elastic member 4012 is filled with a filling material 4013.

The filling material 4013 is, for example, a temperature sensitive material, and when the ambient temperature is higher than a predetermined temperature, the filling material 4013 is in a liquid state, and the second elastic component 4012 and the first elastic component 4011 can be elastically deformed by an external force.

At this time, in the process of engaging or disengaging the buckle 41 with or from the opening of the slot 42, the deformation amount of the first elastic component 4011 is a first deformation amount, and after the buckle 41 is located inside the slot 42 or is disengaged from the slot 42, the deformation amount of the first elastic component 4011 is a second deformation amount, and the first deformation amount is greater than the second deformation amount.

When the ambient temperature is lower than the preset temperature, the filling material 4013 may be changed from a liquid state to a solid state, so that the second elastic member 4012 and the first elastic member 4011 are fixed by the filling material 4013 and cannot be elastically deformed, and at this time, if the clip 41 is located inside the slot 42, the second elastic member 4012 and the first elastic member 4011 cannot be deformed under the action of external force, so that the clip 41 cannot pass through the opening of the slot 42.

The specific material of the filling material 4013 is not limited in the embodiments of the present application. One skilled in the art can select the material of the filling material 4013 according to the critical temperature at which the material of the flexible display 10 becomes brittle. Illustratively, the flexible display screen 10 becomes brittle at-20 deg.C, and the predetermined temperature is, for example, -20 deg.C.

In one implementation of the present application, the filling material 4013 may be transformer No. 25 lubricant or automotive lubricant, and when the ambient temperature is higher than the preset temperature, the filling 4013 is in a liquid state, and when the ambient temperature is lower than the preset temperature, the filling 4013 is solidified. The critical temperature of the transformer 25 lubricating oil or the vehicle lubricating oil is, for example, -20 ℃.

The embodiment of the present application does not limit the specific structures of the buckle 41 and the slot 42, and in an implementation manner of the present application, as shown in fig. 3, the buckle 41 includes: the first elastic component 4011, the first elastic component 4011 is composed of a spring plate, the spring plate encloses a first cavity, and the second elastic component 4012 is located in the first cavity.

The cross-sectional shape of the clip 41 is, for example, a diamond shape or an oval shape. It should be noted that the corners of the diamond are smooth rounded corners, for example, so as to avoid being stuck when entering or exiting the slot 42.

In addition, as shown in fig. 3C and 4C, the clip 41 further includes: a connecting component 4010, and the clip 41 is connected to the second structure 202, for example, via the connecting component 4010.

The embodiment of the present application does not limit the specific structure of the second elastic member 4012. The second elastic component 4012 is, for example, spherical, and the material of the second elastic component 4012 is, for example, plastic.

Referring to fig. 3, the cross-sectional shape of the card slot 42 is a square shape, wherein the cross-sectional height of the opening position of the card slot 42 is y1, the cross-sectional height inside the card slot 42 is y2, y1 and y2 are satisfied: y1 < y 2.

The height of the cross section of the head of the buckle 41 is, for example, y3, and y3 satisfies: y3 < y1 so that the head of the catch 41 can pass through the opening of the catch 42.

The cross-sectional height of the middle position of the clip 41 is, for example, y4, and since the cross-sectional shape of the clip 41 is a diamond shape, y3 and y4 satisfy: y3 < y 4.

In addition, y4 should also satisfy: y4 > y1, so that the buckle 41 can be clamped with the clamping groove 42.

The second elastic member 4012 is fixed, for example, at a central position of the catch 41. The second elastic part 4012 may be connected with an inner sidewall of the clip 41 by gluing. The second elastic member 4012 is filled with a filler material 4013. When the ambient temperature is higher than the preset temperature, the filling material 4013 is in a liquid state, and when the ambient temperature is lower than the preset temperature, the filling material 4013 is cured.

The cross-sectional shape of the second elastic member 4012 is, for example, a circle having a diameter y5, y5 being such that: y1 is more than y5 and less than or equal to y 4. So that when the filling material 4013 is cured inside the second elastic member 4012 and the catch 41 is located inside the catch 42, the catch 41 cannot be pulled out of the opening of the catch 42.

When the ambient temperature is higher than the predetermined temperature, the filling material 4013 in the second cavity is in a liquid state. The operation of the snap assembly 40 is as follows:

in the process of clamping the buckle 41 with the slot 42, the head of the buckle 41 firstly passes through the opening of the slot 42, and then the middle position of the buckle 41 enters the slot 42, at this time, since the sectional height y4 of the middle position of the buckle 41 is greater than the sectional height y1 of the opening of the slot 42, the buckle 41 and the second elastic component 4012 deform, and the deformation amount of the buckle 41 and the second elastic component 4012 is, for example, the first deformation amount.

After the catch 41 has completely entered the catch groove 42, the deformation amount of the catch 41 and the second elastic member 4012 becomes the second deformation amount. Since the cross-sectional height y1 of the opening position of the card slot 42 is smaller than the cross-sectional height y2 inside the card slot 42, the deformation amount of the first deformation is larger than that of the second deformation.

In the process of separating the clip 41 from the slot 42, the clip 41 and the second elastic component 4012 deform again, and the deformation of the clip 41 and the second elastic component 4012 is the first deformation.

After the catch 41 completely leaves the catching groove 42, the deformation amount of the catch 41 and the second elastic member 4012 becomes the second deformation amount.

When the temperature is lower than or equal to the preset temperature, the filling material 4013 in the second cavity is cured, and when an external force is applied, the second elastic component 4012 is extruded and does not deform, at this time, if the clip 41 is located inside the slot 42, the cross-sectional height of the cured second elastic component 4012 is y5, and the middle position of the clip 42 is supported by the second elastic component 4012, so that the cross-sectional height of the middle position of the clip 41 can only be compressed to y5, and since y5 is greater than the cross-sectional height y1 of the opening of the slot 42, the clip 41 cannot be removed from the opening of the slot 42, so that the clip 41 is locked in the slot.

From this, when the ambient temperature in this buckle subassembly place environment was higher than preset temperature, filler 4013 was liquid, can take place deformation, and the shell fragment can freely compress and resume. When the temperature drops below the preset temperature, the filling material is solidified into a solid by liquid, the elastic sheet is prevented from being compressed, and the buckle cannot be pulled out from the opening of the clamping groove.

In another implementation manner of the present application, as shown in fig. 5, the clip 41 further includes: a latch 4014, and the first resilient member 4011 includes: a spring, for example, is provided at the end of the latch 4014. The shape of the clamping groove 42 is matched with the shape of the clamping tongue 4014.

When the latch 4014 is located in the slot 42 or leaves the slot 42, the deformation of the spring is a first deformation, and when the latch 4014 enters the slot 42 or leaves the slot 42, the deformation of the spring is a second deformation; the second amount of deformation is greater than the first amount of deformation.

Wherein the spring is located, for example, in a second cavity, for example, filled with a filler material 4013. Wherein, the second cavity can be enclosed by elastic material and establish the formation, also can enclose by non-elastic material and establish the formation, when filling material 4013 is liquid, the spring can take place flexible deformation in the second cavity, and when filling material 4013 was solid-state, filling material 4013 stopped this spring to take place deformation.

The second cavity is surrounded by an elastic material to form an example. As shown in fig. 5, the second cavity is enclosed by a second elastic component 4012, the second cavity is filled with the filling material 4013, and the spring is located in the second cavity. The embodiment of the present application does not limit the specific structure of the second elastic member 4012. Illustratively, the second resilient member 4012 is, for example, a folded structure, and when the spring is compressed, the folded structure is reduced in axial dimension and increased in sectional dimension, and when the deformation of the spring is restored, the folded structure is restored.

Note that the axial dimension of the folding mechanism is a dimension parallel to the axial direction of the spring, and the cross-sectional dimension of the folding mechanism is a dimension perpendicular to the axial direction of the spring.

The environment that this buckle subassembly is located is the normal atmospheric temperature, and for example when the temperature is about 20 degrees centigrade, filling material 4013 is liquid, and when block tongue 4014 got into draw-in groove 42, the user can promote handle 4015 with compression spring, and at this moment, the deformation volume of spring is first deformation volume.

After the latch 4014 enters the slot 42, the spring has a second deformation. The deformation amount of the first deformation is larger than that of the second deformation.

During the process of separating the latch 4014 from the slot 42, the deformation amount of the spring is a first deformation amount.

After the latch 4014 completely leaves the latch groove 42, the deformation amount of the spring is a second deformation amount.

When the temperature is lower than the preset value, because the filling material 4013 in the second cavity is solidified, the spring in the second cavity is fixed by the filling material 4013, when the latch 4014 is located in the slot 42, the user pushes the handle 4015 to prevent the spring from being compressed, so that the latch 4014 is separated from the opening of the slot 42, and the buckle 41 cannot move relative to the slot by compressing the spring, that is: the catch 41 is locked in the catch groove 42.

This buckle 41 for example also includes: a handle 4015, a handle 4015 is provided on one side of the latch 4014, when the latch 41 is engaged with the slot 42, the latch 4014 is located in the slot 42, and a user can push the handle 4015 to compress the spring, so that the latch 4014 is disengaged from the slot 42.

From this, when ambient temperature is higher than preset temperature, the filler material is liquid, and the spring can freely compress, and this buckle can freely use, when the temperature drops below preset temperature, because the filler material solidifies into solid-state by liquid for second elastic component 4012 receives the extrusion and can not take place deformation, prevents the spring compression, and the buckle can not stir and open.

In one implementation of the embodiments of the present application, the snap assembly 40 of fig. 3 and 5 may be used to fold the display terminal. The embodiment of the present application does not limit the specific arrangement manner of the buckle assembly 40.
