Description

Frame and electronic equipment

Technical Field

The application relates to the technical field of electronic equipment, in particular to a frame and electronic equipment.

Background

With the development of display technology, display screens are increasingly widely used in electronic devices due to the advantages of being flexible and bendable. Generally, a mobile phone manufacturer pastes a screen protection film on a mobile phone display screen when the mobile phone leaves a factory. However, when the display screen is folded, the screen protection film attached to the display screen is easily collided and extruded with the frame, so that the screen protection film is tilted, falls off or damaged from the display screen. How to avoid the tilting, falling or damage caused by the collision between the screen protection film and the frame while ensuring the good working state of the screen is one of the issues continuously explored in the industry.

Disclosure of Invention

The embodiment of the application provides a frame and electronic equipment, can avoid screen protection film and frame to take place the striking and cause the damage when guaranteeing that screen operating condition is good, and the reliability is good.

In a first aspect, the present application provides a bezel, the bezel comprising:

a body having a slot and an inner surface; and

the barricade, the barricade is located the internal surface of body, the barricade includes first end and the second end that sets up along first direction, first end for the second end is close to the fluting, the length of second direction is followed to the second end is greater than or equal to the length of second direction is followed to first end, first direction with the second direction is perpendicular, first direction is for being on a parallel with the direction of internal surface, the second direction is the perpendicular to the direction of internal surface.

It should be noted that the slot can expose the screen protection film and at least part of the display screen, so that a user can see information displayed on the display screen and perform corresponding touch operation on the information displayed on the display screen in time. The inner surface of the body is a surface of the body facing to the accommodating space formed by the frames, a gap is formed between the body and the display screen, and the retaining wall is positioned in the gap.

It can be understood that, because the retaining wall is convexly arranged relative to the inner surface of the body and is positioned in the gap region between the body and the display screen, the retaining wall can be a barrier in the gap region, so that the distance between the frame and the display screen at the position where the retaining wall is positioned is shortened, the risk that the structure in the frame is separated from the gap region to the slot is effectively reduced, and the reliability is good.

And the first end of the retaining wall is close to the slot relative to the second end of the retaining wall. That is, the first end of the retaining wall is the end of the retaining wall close to the slot, and the second end of the retaining wall is the end of the retaining wall far from the slot.

In the technical scheme of the application, the length of the second end of the retaining wall along the second direction can be equal to the length of the first end of the retaining wall along the second direction. When the length of the second end of the retaining wall along the second direction is equal to the length of the first end of the retaining wall along the second direction, the height of the retaining wall is uniform, and the height of the retaining wall is the length of the retaining wall along the second direction.

Alternatively, the length of the second end of the retaining wall along the second direction may also be greater than the length of the first end of the retaining wall along the second direction. When the length of the second end of the retaining wall along the second direction is greater than the length of the first end of the retaining wall along the second direction, the height of the retaining wall is uneven, the retaining wall can be in a structure arrangement with gradually changed height, and the height of the retaining wall is the length of the retaining wall along the second direction.

It can be understood that, when the frame is folded or unfolded, the screen protection film can be elastically deformed when being bent and generate a corresponding elastic deformation acting force. For example, when the frame is changed from the unfolded state to the closed state, the screen protection film can be correspondingly extended and changed along the extending direction of the screen protection film under the action of the elastic deformation force. Under this setting, if the edge of barricade near the screen protection film is the edge, then this edge easily takes place rigidity collision with the screen protection film and leads to the screen protection film to take place the layering with the display screen, and then leads to the screen protection film perk, drops or damaged.

Therefore, the length of the second end along the second direction is larger than that of the first end along the second direction, so that the edge close to the groove in the retaining wall can present a bevel edge structure. On the one hand, this hypotenuse structure has certain guide effect, can fold the operation and expand the operation when the frame, and the guide screen protection film slides in inside the frame gradually for the extension process of screen protection film can be smooth and smooth, thereby improves the smoothness nature that the frame was folded or was expanded. On the other hand, this kind of setting can make the contained angle that is close to grooved edge and body of barricade present gradual change's gentle trend, avoids making the angle change too sharp because of the edges and corners transition to lead to taking place the striking and scratch and make the screen protection film take place the layering with the screen protection film, edge too big pressure to the display screen exerted when can also effectively avoiding the frame to carry out folding operation and expansion operation, can effectively improve the life of screen protection film, and the reliability is good.

Therefore, the retaining wall can be in the form of cambered surface transition or inclined surface transition near the edge of the groove, the guiding effect of the first contact surface is well exerted, layering between the screen protection film and the display screen is avoided, the service life of the screen protection film is effectively prolonged, and the reliability is good.

With the development of display technology, display screens are increasingly widely used in electronic devices due to the advantages of being flexible and bendable. Generally, a screen protection film is covered on the surface of the display screen to play roles of scratch resistance, water resistance, reflection reduction and the like. However, in the folding process of the electronic device, the screen surface layer of the display screen may rub against the screen protection film, and the rubbed screen protection film may extend at the edge of the screen, and if the extension amount is greater than the original distance between the edge of the screen protection film and the frame, the screen protection film may be easily collided and extruded with the frame, and further may cause the screen protection film to tilt up, delaminate from the display screen, or cause the screen protection film to be damaged.

Based on this, the embodiment of this application provides a frame, casing and electronic equipment, can avoid screen protection film and frame to take place the striking and cause the damage when guaranteeing that screen operating condition is good, and the reliability is good.

The electronic device may be any device with foldable performance, which can be unfolded and closed under the operation of a user. Illustratively, the electronic device may be, but is not limited to, a mobile phone, a tablet computer, an e-reader, a notebook computer, a vehicle-mounted device, and the like. In the embodiment of the present application, for convenience of understanding, an electronic device such as a mobile phone having a wide use range and a rich application scenario is taken as an example for description, but the present application is not limited thereto.

Fig. 2 is a schematic structural diagram of the electronic device 300 shown in fig. 1 in an intermediate state, wherein an unfolding angle α of the electronic device 300 is 120 degrees, and α may be other angles. Fig. 3 is a schematic structural diagram of the electronic device 300 shown in fig. 1 in an unfolded state, wherein an unfolding angle β of the electronic device 300 is about 180 degrees.

As shown in fig. 1 to 3, the left and right sides of the electronic device 300 rotate around the rotation center thereof to realize left and right rotation, and the folding and unfolding of the electronic device 300 affects the width dimension of the electronic device 300. It is understood that the electronic device 300 can be divided into an upper portion and a lower portion, the upper portion and the lower portion can rotate around the rotation center thereof to rotate up and down, and the folding and unfolding of the electronic device 300 affects the length and size of the electronic device 300, which will not be described in detail herein.

The angles illustrated in the above embodiments are all allowed to have a slight deviation. For example, the unfolding angle α of the electronic device 300 shown in fig. 2 is 120 degrees, which means that α may be 120 degrees, or may be about 120 degrees, such as 115 degrees or 125 degrees. The unfolding angle β of the electronic device 300 shown in fig. 3 is 180 degrees, which means that β may be 180 degrees, or may be about 180 degrees, such as 185 degrees or 190 degrees.

The electronic device 300 according to the embodiment of the present application is an electronic device that can be folded once. In other embodiments, the electronic device 300 may also be an electronic device that can be folded multiple times (more than two times). At this time, the electronic device 300 may include a plurality of portions, and adjacent two portions may be relatively closely folded to a folded state of the electronic device 300 and adjacent two portions may be relatively far unfolded to an unfolded state of the electronic device 300.

Fig. 4 is a schematic structural diagram of an electronic device 300 according to an embodiment of the present application, and fig. 5 is an exploded schematic diagram of the electronic device 300 shown in fig. 4.

As shown in fig. 4 and 5, the electronic device 300 may include a housing 200, a connection structure (not shown), a display screen 320, and a screen protection film 330. The housing 200, the display screen 320, and the screen protection film 330 may be foldable components that can be opened and closed. It should be understood that the following description will be made by taking the case 200 as an example of the electronic device 300 with folding capability, but the following structural improvement on the case 200 can also be applied to the electronic device 300 without folding capability without conflicting with other structures, and the embodiment of the present application is not limited thereto.

Fig. 6 is a partial sectional view of the housing 200 of fig. 4 taken along line a-a. In which, for ease of illustration, fig. 6 shows only a portion of a cross-sectional schematic view of the housing 200 taken along line a-a, such as the portion shown in the circle on the left side of fig. 4.

As shown in fig. 6, the housing 200 has a housing space 201 and a slot 202. The housing space 201 can house components of the electronic device 300 such as the display screen 320 and the screen protection film 330. The slot 202 is communicated with the accommodating space 201 and the space outside the housing 200, and the screen protection film 330 and at least a part of the display screen 320 can be exposed out of the slot 202, so that a user can see information displayed on the display screen 320 and perform corresponding touch operation on the information displayed on the display screen 320 in time.

The connecting structure 310 is located inside the accommodating space 201 and connected with the housing 200. The connection structure 310 may be located at the edge of the slot 202 and arranged around the slot 202 to have a sufficient contact area with the housing 200, thereby ensuring the connection stability and reliability with the housing 200.

Fig. 7 is a cross-sectional view of the connection structure 310 shown in fig. 6 when the housing 200 is not pressurized. It should be noted that the pressure maintaining of the casing 200 means that the casing 200 may have a plurality of portions, and after dispensing is performed at the positions where the plurality of portions are connected, the casing 200 is pressed by an external pressing fixture to extrude the casing 200, so that the casing 200 is compressed under stress, the adhesive effect of the glue is improved, the problem that the casing 200 formed by connecting the plurality of portions has a gap and a glue at the connection position is avoided, and the plurality of portions forming the casing 200 can be firmly adhered together and are not easy to fall off.

As shown in fig. 7, the connection structure 310 may include an adhesive layer 3101, a foam layer 3102, and a support film layer 3103, which are stacked. The adhesive layer 3101 is provided on the foam layer 3102 on the side facing the case 200, and can be adhered to the case 200. The foam layer 3102 is disposed between the adhesive layer 3101 and the support film layer 3103, and by disposing the foam layer 3102, the rigid collision between the components in the electronic device 300 and the housing 200 can be effectively avoided due to the good elasticity of the foam layer 3102, thereby achieving a good buffering effect. The support film layer 3103 is provided on the side of the foam layer 3102 facing the display screen 320 and can be connected to the foam layer 3102.

The support film layer 3103 may include a first structural layer 3104 and a second structural layer 3105, the first structural layer 3104 being closer to the foam layer 3102 than the second structural layer 3105. That is, the first structural layer 3104 is disposed between the foam layer 3102 and the second structural layer 3105.

Illustratively, the first structure layer 3104 may be a release film, which may have a thickness of 0.09 mm; the second structural layer 3105 may be a contoured film, which may have a thickness of 0.04 mm.

As shown in block diagram in fig. 7, the edge of the second structural layer 3105 may extend outward relative to the edge of the first structural layer, and the portion of the second structural layer 3105 extending relative to the first structural layer 3104 may allow a working space for a worker to manually tear the support film layer 3103 from the foam layer 3102, so that the worker can tear the support film layer 3103 from the foam layer 3102 after the pressure holding of the housing 200 is completed.

As shown in fig. 7, the support film layer 3103 covers the surface of the foam layer 3102 to protect the foam layer 3102 during the process of not and fully pressurizing the housing 200. Meanwhile, the supporting film 3103 also plays a role in preventing the housing 200 from being stressed and deformed and directly pressing the display screen 320 when the housing 200 is pressurized, so that the consistency of the gap between the housing 200 and the display screen 320 is ensured, the display screen 320 is protected from being damaged due to extrusion, the service life of the display screen 320 is effectively prolonged, and the overall working reliability of the electronic device 300 is improved.

Fig. 8 is a sectional view of the connection structure 310 shown in fig. 7 after the pressure holding of the case 200 is completed. Among other things, the connection structure 310 may include an adhesive layer 3101, a foam layer 3102 and not include a support film layer 3103.

As shown in fig. 8, after the pressure holding of the case 200 is completed, the support film layer 3103 may be torn off from the foam layer 3102 so that the foam layer 3102 can sufficiently exert its cushioning effect.

Fig. 9 is a schematic top view of a portion of the connection structure 310 shown in fig. 8. In fig. 9, for the sake of convenience of illustration, the adhesive layer 3101 is not shown, and the foam layer 3102 and the support film layer 3103 are sequentially laminated.

As shown in fig. 9, the connecting structure 310 may further include a tear 3106, and the tear 3106 may be provided on a side of the support film layer 3103 facing away from the foam layer 3102. Tearing the hand 3106 through increasing can be convenient for the staff to tear the supporting film layer 3103 from the foam layer 3102, so that the overall mounting and pasting process of the connecting structure 310 is simpler and faster, and the mounting and pasting efficiency of the connecting structure 310 is favorably improved.

Referring again to fig. 8, the display screen 320 can be used to display information and provide an interactive interface for a user, and the display screen 320 can be unfolded when the housing 200 is unfolded and can be folded when the housing 200 is folded. Illustratively, the display screen 320 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini-organic light-emitting diode (mini-OLED) display screen, a micro-organic light-emitting diode (micro-OLED) display screen, a quantum dot light-emitting diode (QLED) display screen.

In one possible embodiment, as shown in fig. 6, the display screen 320 may include a cover plate 3201 and a display panel 3202, the cover plate 3201 is attached to the display panel 3202, and the display panel 3202 is enclosed by the cover plate 3201 and the housing 200 to be isolated from the external environment. The cover plate 3201 serves to protect the display panel 3202, which may provide tactile and force feedback to a user when the user touches. Among them, the display panel 3202 may be a flexible display panel, i.e., it may have flexibility and be adapted to be bent. The shape of the cover 3201 may be adapted to the shape of the display panel 3202, for example, when the display panel 3202 is a curved panel, the cover 3201 may be a curved cover.

Fig. 10 is a schematic cross-sectional view of the display screen 320 shown in fig. 6. The housing 200 in fig. 10 is a schematic diagram for convenience, and the configuration shown does not represent the actual configuration of the housing 200.

As shown in fig. 10, the display screen 320 may include a display area 3203 and a non-display area 3204, the non-display area 3204 being connected with the display area 3203 and located at a periphery of the display area 3203. The display area 3203 may be an area in the display screen 320 where an image can be displayed, and the non-display area 3204 may be an area in the display screen 320 where an image is not displayed.

The display area 3203 may be exposed through the slot 202, and the non-display area 3204 may be located inside the accommodating space 201. With this arrangement, the outline of the display surface of the display area 3203 capable of displaying is the outline of the display screen 320, and the non-display area 3204 not requiring displaying can be used to connect with the housing 200. No other structures except the display area 3203 occupy the display space, so that the entire surface of the display screen 320 exposed in the external environment can display images, and the electronic device 300 using the display screen 320 can realize full-screen display of the front of the electronic device 300, thereby realizing an ultra-narrow frame or even no frame.

In the embodiment of the present application, the screen protection film 330 is attached on the display screen 320, and the screen protection film 330 may cover only the display area 3203 and not the non-display area 3204. The screen protection film 330 can protect the display screen 320, reduce the risk of damage to the display screen 320, and improve the service life of the display screen 320 and the electronic device 300. The shape of the screen protection film 330 can be adapted to the shape of the display screen 320 to better protect the display screen 320, and because of its flexibility, it can be unfolded with the unfolding of the display screen 320 and folded with the folding of the display screen 320. In addition, the screen protection film 330 has good light transmittance, so that image information displayed on the display screen 320 can be clearly displayed in the field of view of the user.

It should be noted that the thickness and the material of the screen protection film 330 may be selected according to the practical application requirement of the electronic device 300, and the embodiment of the present application is not limited thereto.

Referring to fig. 4 and 5 again, the housing 200 may include a first sub-housing 210 and a second sub-housing 220, and the first sub-housing 210 and the second sub-housing 220 can perform relative folding and relative unfolding actions to switch the housing 200 between a closed state, an intermediate state, and a flat state, and can be maintained in the closed state or the flat state.

Specifically, as shown in fig. 1, the first sub-housing 210 and the second sub-housing 220 may be relatively folded to a closed state, so that the housing 200 is in the closed state. The closed state of the housing 200 can also be understood as the closed state of the electronic device 300, and when the electronic device 300 is in the closed state, the plane size of the electronic device 300 is small, which is convenient for the user to store and carry. Illustratively, when the first sub-housing 210 and the second sub-housing 220 are in the closed state, the first sub-housing 210 and the second sub-housing 220 can be completely folded to be parallel to each other (a slight deviation is also allowed).

As also shown in fig. 2, the first sub-housing 210 and the second sub-housing 220 can also relatively rotate around the rotation axis to approach (fold) each other or move away (unfold) each other to an intermediate state, such that the housing 200 is in the intermediate state, wherein the intermediate state can be any state between the flat state and the closed state. The intermediate state of the housing 200 may also be understood as an intermediate state of the electronic device 300. For example, when the first sub-housing 210 and the second sub-housing 220 are in the intermediate state, the included angle between the first sub-housing 210 and the second sub-housing 220 may be 135 °, 90 °, 45 °, or the like, for example.

As further shown in fig. 3, the first sub-housing 210 and the second sub-housing 220 can be relatively unfolded to be in a flat state, so that the housing 200 is in a flat state. The flat state of the housing 200 can also be understood as a flat state of the electronic device 300, when the electronic device 300 is in the flat state, the plane size of the electronic device 300 is larger, the display screen 320 is flat and in the flat state, and at this time, the display screen 320 can perform full-screen display, so that the electronic device 300 has a larger display area and can present a large-screen display effect. Illustratively, when the first sub-housing 210 and the second sub-housing 220 are in the flattened state, the included angle between the first sub-housing 210 and the second sub-housing 220 may be set to be substantially 180 ° (some deviation is also allowed, such as 175 °, 178 °, or 185 °, etc.).

Based on the above description, it should be understood that the housing 200 can be switched between the closed state and the flattened state, and can be maintained in the closed state or the flattened state.

As shown in fig. 6, the housing 200 may include a base 230 and a bezel 100, and in fig. 5, a portion corresponding to an upper portion of a dotted line drawn in the housing 200 is the bezel 100, and a portion below the dotted line is the base 230. The base 230 and the bezel 100 may cooperate to form the receiving space 201 described above. The base 230 can house components within the electronic device 300. The bezel 100 is connected to the base 230, and can serve as a connecting link between the display screen 320 and the base 230, and the bonding strength between the bezel 100 and the base 230 needs to ensure the connection stability of the display screen 320. In addition, the frame 100 should have a certain elasticity to buffer the rigid extrusion between the display screen 320 and the base 230 caused by falling, bumping, etc., so as to prevent the display screen 320 from being broken.

Both the base 230 and the bezel 100 may extend from the first sub-housing 210 to the second sub-housing 220. That is, a portion of the first sub-housing 210 and a portion of the second sub-housing 220 may together constitute the base 230, and another portion of the first sub-housing 210 and another portion of the second sub-housing 220 may together constitute the bezel 100. In other words, a portion of the base 230 and a portion of the bezel 100 may together constitute the first sub-housing 210, and another portion of the base 230 and another portion of the bezel 100 may together constitute the second sub-housing 220. The composition relationship between the base 230 and the bezel 100 and the first and

second sub-housings

210 and 220 will not be described in detail below, but it should be understood that each part constituting the base 230 and the bezel 100 can extend from the first sub-housing 210 to the second sub-housing 220.

In one possible embodiment, a protrusion may be provided in one of the base 230 and the bezel 100, and a groove may be provided in the other of the base 230 and the bezel 100, and the base 230 and the bezel 100 may be connected by dispensing and snapping the adhesive into the groove. It should be noted that, due to the extrusion, the frame 100 is subjected to the extrusion stress during the fastening, and in order to avoid the extrusion stress from affecting the bonding strength between the frame 100 and the base 230 due to the springback, the frame 100 needs to be extruded and pressure-maintained during the fastening of the frame 100 and the base 230 until the glue is cured.

It should be understood that the base 230 of the embodiment of the present application is only an example, and the specific structure of the base 230 and the connection position thereof with the bezel 100 are not strictly limited.

Referring to fig. 6 again, the frame 100 may include a body 10, a protrusion 20 and a retaining wall 30. The length direction of the frame 100 is defined as a first direction, the height direction of the frame 100 is defined as a second direction, and the first direction is perpendicular to the second direction, for example, the first direction is denoted by X, and the second direction is denoted by Z. It should be noted that the first direction X may be equivalent to a length direction of the housing 200 and/or a length direction of the electronic device 300, and the second direction Z may be equivalent to a height direction of the housing 200 and/or a height direction of the electronic device 300.

The body 10 includes an inner surface 101 and an outer surface 102. The outer surface 102 of the body 10 is the surface of the body 10 exposed to the external environment, and may form the appearance surface of the housing 200 together with the outer surface of the base 230. The inner surface 101 of the body 10 is a surface of the body 10 facing the receiving space 201, and a gap may be provided between the body 10 and the display screen 320, and the gap may provide a receiving space for the connecting structure 310. Illustratively, the gap width between the body 10 and the display screen 320 may be in the range of 0.05 mm-0.12 mm (inclusive of 0.05 mm and 0.12 mm).

The slot 202 may be a space formed around the body 10, the slot 202 penetrates through the outer surface 102 of the body 10 and the inner surface 101 of the body 10 along the second direction Z, and the slot 202 can expose the screen protection film 330 and the display screen 320. The slot 202 may be located at an intermediate position of the body 10 so that the body 10 as a whole has a hollow ring shape. When the user holds the electronic device 300, the screen protection film 330 and the display screen 320 covered by the screen protection film 330 can be seen through the slot 202, and the user can see the information displayed by the display screen 320 because the display screen 320 is exposed.

The protrusion 20 of the frame 100 may be disposed around the inner surface 101 of the body 10, and the protrusion 20 is located on the outer edge of the inner surface 101 of the body 10 and away from the slot 202 of the body 10. The boss 20 is used to connect with the base 230. That is, the protrusion 20 is annular and protrudes with respect to the body 10. Through setting up convex part 20, can be because of the setting of convex part 20 protruding locating body 10, and make convex part 20 have the positioning action, be favorable to making frame 100 realize counterpointing fast with base 230, and then make frame 100 and base 230 can realize the assembly fast.

The wall 30 of the frame 100 may be disposed on the inner surface 101 of the body 10, and the wall 30 is located in a gap region between the body 10 and the display screen 320. In addition, the retaining wall 30 is located at the inner edge of the inner surface 101 of the body 10 and adjacent to the slot 202 of the body 10. That is, the retaining wall 30 is disposed adjacent to the slot 202 relative to the protrusion 20. In other words, in the first direction X, the retaining wall 30 and the protrusion 20 are disposed opposite to each other with a certain distance therebetween. By arranging the retaining wall 30 and the protrusion 20 oppositely in the first direction X, a space required for arranging the connecting structure 310 can be reserved, and the connecting structure 310 can be ensured to be located in a gap area between the retaining wall 30 and the protrusion 20.

It can be understood that, since the retaining wall 30 is disposed to protrude from the inner surface 101 of the body 10, and the retaining wall 30 is located in the gap region between the body 10 and the display screen 320, the retaining wall 30 can be a barrier in the gap region, so that the distance between the frame 100 and the display screen 320 where the retaining wall 30 is located is shortened, and the risk that the connection structure 310 is released from the gap region to the slot 202 is effectively reduced, that is, the connection structure 310 in fig. 9 is prevented from sliding out in the direction close to the retaining wall 30, and the reliability is good.

With reference to fig. 6, the retaining wall 30 includes a first end 31 and a second end 32 along the first direction X, and the first end 31 of the retaining wall 30 is close to the slot 202 relative to the second end 32 of the retaining wall 30. That is, the first end 31 of the retaining wall 30 is the end of the retaining wall 30 close to the slot 202, and the second end 32 of the retaining wall 30 is the end of the retaining wall 30 far from the slot 202.

In the embodiment of the present application, the length of the second end 32 of the retaining wall 30 along the second direction Z may be greater than the length of the first end 31 of the retaining wall 30 along the second direction Z. When the length of the second end 32 of the retaining wall 30 along the second direction Z is greater than the length of the first end 31 of the retaining wall 30 along the second direction Z, the height of the retaining wall 30 is not uniform, and it can be set in a structure with gradually changed height, and the height of the retaining wall 30 is the length of the retaining wall 30 along the second direction Z.

Fig. 11 is a schematic view showing a state in which the housing 200 shown in fig. 6 is folded. In fig. 6, the screen protection film 330 is in the initial position B when the housing 200 is not folded, and in fig. 11, the screen protection film 330 is in the twisting position C when the housing 200 is folded.

It can be understood that, when the frame 100 is folded or unfolded, the screen protection film 330 is elastically deformed when being bent and generates a corresponding elastic deformation force. For example, when the frame 100 is changed from the flat state to the closed state, the screen protection film 330 is correspondingly changed in extension along the extending direction of the screen protection film 330 by the elastic deformation force, such as extending from the initial position B of the screen protection film 330 in the flat state shown in fig. 6 to the twisting position C of the screen protection film 330 in the closed state shown in fig. 11. Under this configuration, if the edge of the retaining wall 30 close to the screen protection film 330 is an edge, the edge is prone to rigidly collide with the screen protection film 330 to cause the screen protection film 330 and the display screen 320 to be layered, and further cause the screen protection film 330 to tilt, fall off or be damaged.

Thus, by setting the length of the second end 32 in the second direction Z to be greater than the length of the first end 31 in the second direction Z, the edge of the retaining wall 30 near the slot 202 can be made to assume a beveled configuration. On one hand, the bevel edge structure has a certain guiding function, and can guide the screen protection film 330 to gradually slide into the frame 100 when the frame 100 is folded and unfolded, so that the extending process of the screen protection film 330 can be smooth and smooth, and the folding or unfolding fluency of the frame 100 is improved. On the other hand, this kind of setting can make the contained angle that is close to fluting 202 of barricade 30 and body 10 present gradual change's gentle trend, avoid making the angle change too sharp because of the edges and corners transition, thereby lead to taking place the striking and scrape and make screen protection film 330 and display screen 320 take place the layering with screen protection film 330, the too big pressure that the edge applyed to display screen 320 when can also effectively avoiding frame 100 to carry out folding operation and expansion operation, can effectively improve screen protection film 330's life, good reliability.

It should be noted that the first direction X defined herein may also be equivalent to a direction parallel to the inner surface 101, and the second direction Z may also be equivalent to a direction perpendicular to the inner surface 101.

Fig. 12 is a schematic diagram of a shape change of the bezel 100 before and after pressing according to an embodiment of the present application.

In the embodiment of the present application, the frame 100 satisfies the following relation:

wherein y (X) is a length of the first end 31 of the retaining wall 30 along the first direction X, h (X) is a length of the second end 32 of the retaining wall 30 along the second direction Z, h is a length from the inner surface 101 of the body 10 to the screen protection film 330 (which can also be understood as a surface of the display screen 320) in the second direction Z, l (X) is a length from the groove 202 to an edge of the body 10 in the second direction Z, and θ is a variation of an included angle between the body 10 and the screen protection film 330 (which can also be understood as a surface of the display screen 320) when the body 10 is deformed by a force during pressure maintaining until the retaining wall 30 contacts the screen protection film 330.

When the pressure is not maintained in the housing 200, the main body 10 is not deformed due to no force, and the included angle between the main body 10 and the screen protection film 330 is not changed. When the casing 200 is pressurized, the body 10 is gradually deformed by a force, the body 10 gradually approaches the screen protection film 330, and an included angle θ between the body 10 and the screen protection film 330 gradually increases. In other words, θ can be understood as an angle that the body 10 rotates when the body 10 is switched from an initial state where the body 10 is not pressurized to a pressurized state of the body 10.

Illustratively, when the main body 10 is not pressurized, the angle of the included angle between the main body 10 and the screen protection film 330 (which may also be understood as the display screen 320) is denoted as θ 1. In the pressure maintaining state of the main body 10, an angle of an included angle between the main body 10 and the screen protection film 330 (which may also be understood as the display screen 320) is denoted as θ 2, and θ = θ 2- θ 1.

Structural modifications of the other three retaining walls 30 will be described in detail below.

The first embodiment is as follows:

fig. 13 is a first structural view of the first embodiment of the rim 100 of the casing 200 of fig. 4 taken along line a-a, and fig. 14 is an enlarged view of the area E1 of fig. 13. In which, for ease of illustration, fig. 13 only cuts a portion of the schematic cross-sectional view of the housing 200 taken along line a-a, such as the portion shown in the circle on the left side of fig. 4.

As shown in fig. 13 and 14, in this embodiment, the retaining wall 30 includes a connecting surface 33 and a first contact surface 34, and the connecting surface 33 and the first contact surface 34 together constitute an appearance surface of the retaining wall 30.

Fig. 15 is a bottom view of the bezel 100 shown in fig. 13. In fig. 15, only the bezel 100 is illustrated, and none of the connection structure 310, the display screen 320, and the screen protection film 330 is illustrated.

Specifically, as shown in fig. 14 and 15, the connection surface 33 is connected to the inner surface 101 of the body 10, and the connection point between the connection surface 33 and the inner surface 101 of the body 10 is a first intersecting line F. The first contact surface 34 is connected between the inner surface 101 of the body 10 and the connection surface 33, and the connection position of the first contact surface 34 and the inner surface 101 of the body 10 is a second intersecting line G, and the second intersecting line G is close to the slot 202 relative to the first intersecting line F. That is, the first contact surface 34 is a surface of the wall 30 close to the slot 202, and the connection surface 33 is a surface of the wall 30 far from the slot 202.

The body 10 further includes a peripheral side surface 103 connected to the inner surface 101, the peripheral side surface 103 defining a slot 202. The junction between the peripheral surface 103 of the body 10 and the inner surface 101 of the body 10 is a third intersecting line H. As shown in fig. 15, when the second intersecting line G coincides with the third intersecting line H, that is, the second intersecting line G is a connection point between the peripheral side surface 103 of the body 10 and the inner surface 101 of the body 10, as shown in fig. 14, the first contact surface 34 may be connected to the peripheral side surface 103 of the body 10.

Fig. 16 is a second structural diagram of the first embodiment of the bezel 100 taken along line a-a of the housing 200 shown in fig. 4, fig. 17 is an enlarged diagram of area E2 shown in fig. 16, and fig. 18 is a bottom diagram of the bezel 100 shown in fig. 16. In fig. 18, only the bezel 100 is illustrated, and none of the connection structure 310, the display screen 320, and the screen protection film 330 is illustrated.

When the second intersecting line G is disposed at a distance from the third intersecting line H as shown in fig. 18, the first contact surface 34 may be connected only to the inner surface 101 and the connection surface 33 of the body 10, and not to the circumferential side surface 103 of the body 10 as shown in fig. 17.

In this embodiment, the first contact surface 34 is disposed obliquely to the inner surface 101 of the body 10. Referring to fig. 13, the first contact surface 34 may be a plane surface, so that the edge of the retaining wall 30 near the slot 202 is in a slope transition form, and in this arrangement, the slope of the inclined edge of the retaining wall 30 is a constant value.

Fig. 19 is a third structural view of the first embodiment of the rim 100 of the case 200 of fig. 4 taken along line a-a, and fig. 20 is an enlarged view of area E3 of fig. 19. As shown in fig. 20, the first contact surface 34 may also be curved, so that the edge of the wall 30 near the slot 202 is curved, and the slope of the inclined edge of the wall 30 is changed.

With this arrangement, the first contact surface 34 is a surface of the retaining wall 30 that can guide the screen protection film 330 to slide into the gap area between the frame 100 and the display screen 320 during the folding operation and the unfolding operation of the frame 100. By obliquely disposing the first contact surface 34 and the inner surface 101 of the body 10, the length of the retaining wall 30 along the second direction Z can be disposed in a gradually changing manner in the first direction X (i.e., the height of the retaining wall 30 gradually changes in the first direction X). Therefore, the edge of the retaining wall 30 close to the slot 202 can be in an arc transition or slope transition form, so that the guiding effect of the first contact surface 34 is well exerted, the screen protection film 330 and the display screen 320 are prevented from being layered, the service life of the screen protection film 330 is effectively prolonged, and the reliability is good. In addition, when the housing 200 is deformed downward under the pressure maintaining force, the first contact surface 34 and the inner surface 101 of the body 10 are inclined, so that the retaining wall 30 and the display screen 320 are in surface-to-surface contact, the problem that the edge of the retaining wall 30 presses the screen to concentrate the display screen 320 on the contact edge to bear the force can be effectively avoided, the display screen 320 is protected from being damaged, and the reliability is high.

Example two:

fig. 21 is a first structural view of a second embodiment of the bezel 100 of the housing 200 of fig. 4 taken along line a-a, and fig. 22 is an enlarged view of area E4 of fig. 21.

In this embodiment, the same contents as those in the first embodiment are not repeated, and different from the first embodiment, as shown in fig. 22, the retaining wall 30 further includes a second contact surface 35, and the connection surface 33, the first contact surface 34 and the second contact surface 35 together form an appearance surface of the retaining wall 30.

Fig. 23 is a bottom view of the bezel 100 shown in fig. 21. In fig. 23, only the bezel 100 is illustrated, and none of the connection structure 310, the display screen 320, and the screen protection film 330 is illustrated.

Specifically, as shown in fig. 22 and 23, the connection surface 33 is connected to the inner surface 101 of the body 10, and the connection point between the connection surface 33 and the inner surface 101 of the body 10 is a first intersecting line F. The first contact surface 34 is connected with the inner surface 101 of the body 10, and a second intersection line G is formed at the connection position of the first contact surface 34 and the inner surface 101 of the body 10, and the second intersection line G is close to the slot 202 relative to the first intersection line F. That is, the first contact surface 34 is a surface of the wall 30 close to the slot 202, and the connection surface 33 is a surface of the wall 30 far from the slot 202. The second contact surface 35 is connected between the connection surface 33 and the first contact surface 34.

The body 10 further includes a peripheral side surface 103 connected to the inner surface 101, the peripheral side surface 103 is surrounded by a slot 202, and a third intersecting line H is formed at a connecting position of the peripheral side surface 103 of the body 10 and the inner surface 101 of the body 10. As shown in fig. 23, when the second intersecting line G coincides with the third intersecting line H, that is, the second intersecting line G is a connection point between the peripheral side surface 103 of the body 10 and the inner surface 101 of the body 10, as shown in fig. 22, the first contact surface 34 may be connected to the peripheral side surface 103 of the body 10.

Fig. 24 is a second structural view of the second embodiment of the bezel 100 of fig. 4 taken along line a-a of the housing 200, fig. 25 is an enlarged view of area E5 of fig. 24, and fig. 26 is a bottom view of the bezel 100 of fig. 24. In fig. 26, only the bezel 100 is illustrated, and none of the connection structure 310, the display screen 320, and the screen protection film 330 is illustrated.

When the second intersecting line G is disposed at a distance from the third intersecting line H as shown in fig. 26, the first contact surface 34 may be connected only to the inner surface 101 and the connection surface 33 of the body 10, not to the circumferential side surface 103 of the body 10, as shown in fig. 25.

In this embodiment, the first contact surface 34 is disposed obliquely to the inner surface 101 of the body 10. Referring to fig. 22, the first contact surface 34 may be a plane surface, so that the edge of the retaining wall 30 near the slot 202 is in a slope transition form, and in this arrangement, the slope of the inclined edge of the retaining wall 30 is a constant value.

Fig. 27 is a third structural view of the second embodiment of the bezel 100 of the housing 200 of fig. 4 taken along line a-a, and fig. 28 is an enlarged view of area E6 of fig. 27. As shown in fig. 28, the first contact surface 34 may also be curved so that the edge of the wall 30 near the slot 202 has a curved edge transition/curved surface transition configuration, and the slope of the inclined edge of the wall 30 is changed.

With this arrangement, the first contact surface 34 and the second contact surface 35 are surfaces of the retaining wall 30 that can guide the screen protection film 330 to slide into the gap area between the bezel 100 and the display screen 320 during the folding operation and the unfolding operation of the bezel 100. By obliquely disposing the first contact surface 34 and the inner surface 101 of the body 10, the length of the retaining wall 30 along the second direction Z can be disposed in a gradually changing manner in the first direction X (i.e., the height of the retaining wall 30 gradually changes in the first direction X). Therefore, the edge of the retaining wall 30 close to the slot 202 can be in an arc transition or slope transition form, so that the guiding effect of the first contact surface 34 is well exerted, the screen protection film 330 and the display screen 320 are prevented from being layered, the service life of the screen protection film 330 is effectively prolonged, and the reliability is good. In addition, when the housing 200 is deformed downward under the pressure maintaining force, the first contact surface 34 and the inner surface 101 of the body 10 are inclined, so that the retaining wall 30 and the display screen 320 are in surface-to-surface contact, the problem that the edge of the retaining wall 30 presses the screen to concentrate the display screen 320 on the contact edge to bear the force can be effectively avoided, the display screen 320 is protected from being damaged, and the reliability is high.

Example three:

fig. 29 is a first structural view of a third embodiment of the bezel 100 of the case 200 of fig. 4 taken along line a-a, and fig. 30 is an enlarged view of area E7 of fig. 29. In fig. 30, the thick lines are only shown for convenience and are not practical.

In this embodiment, the same contents as those in the second embodiment are not repeated, and different from the second embodiment, as shown in fig. 30, the retaining wall 30 further includes a third contact surface 36, and the connection surface 33, the first contact surface 34, the second contact surface 35, and the third contact surface 36 together form an appearance surface of the retaining wall 30.

Fig. 31 is a bottom view of the bezel 100 shown in fig. 29. In fig. 31, only the bezel 100 is illustrated, and none of the connection structure 310, the display screen 320, and the screen protection film 330 is illustrated.

Specifically, as shown in fig. 30 and 31, the connection surface 33 is connected to the inner surface 101 of the body 10, and the connection point between the connection surface 33 and the inner surface 101 of the body 10 is a first intersecting line F. The first contact surface 34 is connected with the inner surface 101 of the body 10, and a second intersection line G is formed at the connection position of the first contact surface 34 and the inner surface 101 of the body 10, and the second intersection line G is close to the slot 202 relative to the first intersection line F. That is, the first contact surface 34 is a surface of the wall 30 close to the slot 202, and the connection surface 33 is a surface of the wall 30 far from the slot 202. The second contact surface 35 is connected to the connection surface 33, and the extending direction of the second contact surface 35 intersects the extending direction of the first contact surface 34. The third contact surface 36 is connected between the first contact surface 34 and the second contact surface 35.

The body 10 further includes a peripheral side surface 103 connected to the inner surface 101, the peripheral side surface 103 is surrounded by a slot 202, and a third intersecting line H is formed at a connecting position of the peripheral side surface 103 of the body 10 and the inner surface 101 of the body 10. As shown in fig. 31, when the second intersecting line G coincides with the third intersecting line H, that is, the second intersecting line G is a connection point between the peripheral side surface 103 of the body 10 and the inner surface 101 of the body 10, as shown in fig. 30, the first contact surface 34 may be connected to the peripheral side surface 103 of the body 10.

Fig. 32 is a second structural view of the third embodiment of the bezel 100 of fig. 4 taken along line a-a of the housing 200, fig. 33 is an enlarged view of area E8 of fig. 32, and fig. 34 is a bottom view of the bezel 100 of fig. 32. In fig. 34, only the bezel 100 is illustrated, and none of the connection structure 310, the display screen 320, and the screen protection film 330 is illustrated.

When the second intersecting line G is disposed at a distance from the third intersecting line H as shown in fig. 34, the first contact surface 34 may be connected only to the inner surface 101 of the body 10 and the third contact surface 36, as shown in fig. 33, without being connected to the circumferential side surface 103 of the body 10.

In this embodiment, the first contact surface 34 is disposed obliquely to the inner surface 101 of the body 10. The first contact surface 34 may be flat so that the edge of the wall 30 adjacent to the slot 202 is in a slope transition, and in this arrangement, the slope of the sloping edge of the wall 30 is constant. The first contact surface 34 may also be curved so that the edge of the wall 30 near the slot 202 has a curved edge/curved surface transition, and the slope of the inclined edge of the wall 30 is changed.

With this arrangement, the first contact surface 34, the second contact surface 35 and the third contact surface 36 are surfaces of the retaining wall 30 that can guide the screen protection film 330 to slide into the gap area between the bezel 100 and the display screen 320 during the folding operation and the unfolding operation of the bezel 100. By obliquely disposing the first contact surface 34 and the inner surface 101 of the body 10, the length of the retaining wall 30 along the second direction Z can be disposed in a gradually changing manner in the first direction X (i.e., the thickness of the retaining wall 30 gradually changes in the first direction X). Therefore, the edge of the retaining wall 30 close to the slot 202 can be in an arc transition or slope transition form, so that the guiding effect of the first contact surface 34 is well exerted, the screen protection film 330 and the display screen 320 are prevented from being layered, the service life of the screen protection film 330 is effectively prolonged, and the reliability is good. In addition, when the housing 200 is deformed downward under the pressure maintaining force, the first contact surface 34 and the inner surface 101 of the body 10 are inclined, so that the retaining wall 30 and the display screen 320 are in surface-to-surface contact, the problem that the edge of the retaining wall 30 presses the screen to concentrate the display screen 320 on the contact edge to bear the force can be effectively avoided, the display screen 320 is protected from being damaged, and the reliability is high.

Fig. 35 is a third structural view of the third embodiment of the bezel 100 of fig. 4 taken along line a-a of the housing 200, and fig. 36 is an enlarged view of area E9 of fig. 35. The thick lines in fig. 36 are only shown for convenience of illustration and are not of practical significance.

As shown in fig. 30, the third contact surface 36 may be planar such that the first contact surface 34 and the second contact surface 35 present a slope transition. Alternatively, as shown in fig. 36, the third contact surface 36 may be curved, so that the first contact surface 34 and the second contact surface 35 have a curved edge transition/arc transition shape.
