[0016] In order to make the technical solutions in the embodiments of the application clearer, the following will briefly introduce the drawings needed to be used in the embodiment description. Obviously, the drawings in the following description are only some embodiments of the application, and other drawings can be obtained by those skilled in the art without creative effort on the basis of these drawings.

[0017] With the development of communication technology, mobile terminals such as mobile phones and tablets have become indispensable tools for people. Flexible display technology has led to the emergence of various foldable phones on the market. However, existing foldable phones use relatively simple folding forms, such as symmetrical left-right folding or symmetrical up-down folding. At the same time, the use of the unfolded phone is the same as that of traditional smartphones, interacting with electronic devices only through a single display screen, thus failing to provide a rich user experience.

[0018] Based on this, this application provides an electronic device component 1 to improve the above-mentioned problems.

[0019] Please refer to the following: Figure 1 and Figure 2 This application provides an electronic device component 1, including an electronic device 10 and a bendable protective shell 20. The electronic device 10 includes a shell assembly 11, a first display screen 12, and a second display screen 13. The electronic device 10 also includes a motherboard, a battery, a front-facing camera, and a rear-facing camera 14. The motherboard and battery are housed within the shell assembly 11, and the front-facing camera is located on one side of the electronic device 10 where the first display screen 12 is located. The electronic device 10 provided in this embodiment is illustrated using a mobile phone as an example.

[0020] Please see Figure 3 The housing assembly 11 includes a first housing 111, a second housing 112, a third housing 113, a first rotating connector 114, and a second rotating connector 115. Exemplarily, the first housing 111 and the second housing 112 are rotatably connected via the first rotating connector 114, and the second housing 112 and the third housing 113 are rotatably connected via the second rotating connector 115. Exemplarily, a first receiving cavity may be formed within the first housing 111, a second receiving cavity may be formed within the second housing 112, and a third receiving cavity may be formed within the third housing 113. The first housing 111, the second housing 112, and the third housing 113 are connected in a first direction (e.g., ...). Figure 3 The lengths along the direction indicated by the middle arrow can be different, therefore the volumes of the first, second, and third receiving cavities can also be different. In this embodiment, the second housing 112 is the longest in the Y direction than the first housing 111 and the third housing 113, therefore the second receiving cavity has a larger volume. It is understood that in this embodiment, larger components such as batteries and motherboards can be housed within the second receiving cavity. In other embodiments, components such as batteries and motherboards can also be housed in either the first or third receiving cavity; this is not limited here.

[0021] Please refer to the following for details. Figure 2 and Figure 3The first shell 111 can include a first frame 1111, a first back plate 1112 and a first panel, the first back plate 1112 and the first panel are respectively assembled on two sides opposite to the first frame 1111, and the first frame 1111, the first back plate 1112 and the first panel enclose a first accommodating cavity. In the embodiment, the first rotating connecting piece 114 is connected to the first frame 1111. In other embodiments, the first rotating connecting piece 114 can also be directly connected to the first back plate 1112 and the first panel, and by such a design, the side close to the first rotating connecting piece 114 can also not be provided with the first frame 1111. In some embodiments, the rear camera 14 of the electronic device 10 can be arranged on the first shell 111.

[0022] Please continue to refer to Figure 2 and Figure 3 The second shell 112 can include a second frame 1121, a second back plate 1122 and a second panel, the second back plate 1122 and the second panel are respectively assembled on two sides opposite to the second frame 1121, and the second frame 1121, the second back plate 1122 and the second panel enclose a second accommodating cavity. In the embodiment, the first rotating connecting piece 114 connects the first frame 1111 and the second frame 1121.

[0023] The third shell 113 can include a third frame 1131, a third back plate 1132 and a third panel, the third back plate 1132 and the third panel are respectively assembled on two sides opposite to the third frame 1131, and the third frame 1131, the third back plate 1132 and the third panel enclose a third accommodating cavity. In the embodiment, the second rotating connecting piece 115 connects the second frame 1121 and the third frame 1131.

[0024] Since the first shell 111, the second shell 112 and the third shell 113 are connected by the first rotating connecting piece 114 and the second rotating connecting piece 115, the first shell 111, the second shell 112 and the third shell 113 can be relatively unfolded or folded. By such a design, in the process of using the electronic device 10, the electronic device 10 proposed in the application can also be used around the wrist, or by bending, the first shell 111, the second shell 112 and the third shell 113 have a certain angle between each other, so that the electronic device 10 can be placed on the desktop in a specific way, such as the placement shown in Figure 3 , the use is more novel.

[0025] Please refer to Figure 4The first rotating connecting piece 114 is used to rotatably connect the first shell 111 and the second shell 112. Since the first shell 111, the second shell 112 and the third shell 113 need to maintain a certain damping when being unfolded or folded, the first shell 111, the second shell 112 and the third shell 113 can maintain a specific angle and will not rotate under the action of gravity and other forces. Therefore, in the embodiment, the first rotating connecting piece 114 can include a first damping piece 1141, a second damping piece 1142 and a connecting piece 1143. The connecting piece is connected with the first damping piece 1141 and the second damping piece 1142 respectively. The first damping assembly 1141 is connected with the first shell 111, and the second damping piece 1142 is connected with the second shell 112. The first damping piece 1141, the second damping piece 1142 and the connecting piece 1143 can provide a certain damping during the relative rotation of the first shell 111 and the second shell 112.

[0026] Specifically, in the embodiment, the connecting piece 1143 is provided with a first mounting hole, a second mounting hole and a mounting slot. The first mounting hole and the second mounting hole are in communication with the mounting slot. The first damping piece 1141 can be a cylindrical component made of rubber. The first damping piece 1141 is arranged in the first mounting hole and tightly fits with the first mounting hole. During the rotation of the first damping piece 1141 in the first mounting hole, the friction between the first damping piece 1141 and the inner wall of the first mounting hole can provide damping. The connecting rod of the first damping assembly 1141 protrudes from the first mounting hole and is fixedly connected with the first shell 111. The second damping piece 1142 is arranged in the second mounting hole. The second damping piece 1142 protrudes from the second mounting hole and is fixedly connected with the second shell 112. The structure and material of the second damping piece 1142 can be substantially the same as those of the first damping piece 1141, which will not be described herein. It can be understood that the rotating damping refers to the size of the rotating resistance during rotation. The rotating damping represents the size of the rotating torque that hinders rotation generated by the resistance during rotation. It can be understood that the rotating damping can be continuous. For example, in the embodiment, when the first shell 111 rotates relative to the connecting piece, the rotating damping of the first damping piece 1141 continuously changes, and the rotating damping hinders the rotation of the first shell 111 relative to the connecting piece. When the second shell 112 rotates relative to the connecting piece, the rotating damping of the second damping piece 1142 continuously changes, and the rotating damping hinders the rotation of the second shell 112 relative to the connecting piece 1143. However, the rotating damping can provide a clear tactile feedback for the user.

[0027] In some other embodiments, the first shell 111 and the second shell 112 can also be connected by mechanical structures such as gear sets or arc-shaped sliding rails, and the specific connection manner is not limited here. Meanwhile, the specific structure of the second rotating connecting piece 115 is substantially the same as that of the first rotating connecting piece 114, and can refer to the structure of the first rotating connecting piece 114, which is not described here.

[0028] The first display screen 12 can serve as the main display screen of the electronic device 10, and can be used to display main image information such as the interface of the electronic device 10. In the embodiment, please refer to Figure 2 , the first display screen 12 is continuously arranged on the first shell 111, the second shell 112 and the third shell 113 to obtain a larger display area. Specifically, the first display screen 12 can be simultaneously assembled on the first panel, the second panel and the third panel. In the embodiment, the first display screen 12 is also arranged on the first rotating connecting piece 114 and the second rotating connecting piece 115. Since the first shell 111, the second shell 112 and the third shell 113 can be relatively unfolded or folded, the first display screen 12 can be a flexible display screen, so that the first shell 111, the second shell 112 and the third shell 113 are all attached to the first display screen 12 during the process of being unfolded or folded. For example, the first display screen 12 can be an OLED (Organic Light-Emitting Diode) screen for displaying information, which can be an AMOLED (Active Matrix Organic Light Emitting Diode) screen or a Super AMOLED (Super Active Matrix Organic Light Emitting Diode) screen or a Super AMOLED Plus (Super Active Matrix Organic Light Emitting Diode Plus) screen, which is not described here, and the first display screen 12 can be a touch display screen.

[0029] Please continue to refer to Figure 2The second display screen 13 can be used as a secondary display screen of the electronic device 10, and can be used to display image information different from the first display screen 12 or to perform human-computer interaction, such as displaying incoming calls, short messages, messages, etc., which is not limited herein. The second display screen 13 is arranged on the first housing 111 and opposite to the first display screen 12. The second display screen 13 can be adjacent to the rear camera 14 on the first housing 111. In some application scenarios, when the electronic device 10 is used around the wrist or is placed on a desktop, the second display screen 13 can display, for example, a watch face, time, calendar, etc., to provide a better user experience. In this state, the second display screen 13 can be used to display image information only. Since the display area of the second display screen 13 can be smaller than that of the first display screen 12, using the second display screen 13 to display information only can reduce power consumption and prolong the battery life. The second display screen 13 can be an LCD (Liquid Crystal Display) screen for displaying information, which can be a TFT (Thin Film Transistor) screen or an IPS (In-Plane Switching) screen or an SLCD (Splice Liquid Crystal Display) screen. In other embodiments, the second display screen 13 can also be an OLED screen for displaying information, which can be an AMOLED screen or a Super AMOLED screen or a Super AMOLED Plus screen, which is not described herein again. The second display screen 13 can also be a touch display screen. Since the rear camera 14 is adjacent to the second display screen 13 and located on the same side of the electronic device 10 as the second display screen 13, and the rear camera 14 usually has higher pixels, resolution and zoom ratio, when a selfie operation is needed, the rear camera 14 can be used and the real-time image can be displayed on the second display screen 13 to obtain a better selfie effect.

[0030] When the electronic device 10 is used around the wrist only by relatively unfolding or folding the first housing 111, the second housing 112 and the third housing 113, the electronic device 10 can be easily detached or the space formed by the electronic device 10 can be too small to be inconvenient when worn on the wrist. Based on this, the inventors think that most of the current electronic devices 10 have corresponding protective cases 20 for protecting the electronic devices 10 from wear and tear or falling, so the electronic device assembly 1 proposed in the present application further includes a bendable protective case 20, which is described again with reference to Figure 1 The protective case 20 is used in cooperation with the electronic device 10, and the first housing 111, the second housing 112 and the third housing 113 are prolonged by the protective case 20 Figure 1In order to improve the above problems, the length of the direction of the arrow is increased. Specifically, the protective shell 20 is connected with the electronic device 10, the protective shell 20 includes opposite first end 21 and second end 22, the first end 21 and the second end 22 can be two ends of the length direction of the protective shell 20, the first end 21 and the second end 22 are provided with the connecting structure matched with each other. When the electronic device 10 is accommodated in the accommodating space, by connecting the first end 21 with the second end 22, the electronic device assembly 1 can form a closed ring structure, which is not easy to fall off when worn on the wrist, and is also more beautiful.

[0031] For example, in the embodiment, please refer to Figure 1 and Figure 5 , the protective shell 20 can include a bottom shell 23 and a side shell 24, the side shell 24 is arranged around the edge of the bottom shell 23 and forms an accommodating space with the bottom shell 23, the bottom shell 23 includes a first bottom shell 231, a second bottom shell 232 and a third bottom shell 233, the second bottom shell 232 is connected between the first bottom shell 231 and the third bottom shell 233 and can be folded relative to the first bottom shell 231 and the third bottom shell 233, when the electronic device 10 is accommodated in the accommodating space, the first shell body 111 corresponds to the first bottom shell 231, the second shell body 112 corresponds to the second bottom shell 232, and the third shell body 113 corresponds to the third bottom shell 233. For example, the entire protective shell 20 can also be made of flexible material to realize the folding of the second bottom shell 232 relative to the first bottom shell 231 and the third bottom shell 233.

[0032] It can be understood that the bottom shell and the first display screen 12 in the electronic device 10 are located on opposite sides, so that when the user uses the first display screen 12, the display screen of the first display screen 12 can be avoided by the protective shell 20. Through such design, the first shell body 111, the second shell body 112 and the third shell body 113 will not be separated from the corresponding first bottom shell 231, second bottom shell 232 and third bottom shell 233 during the process of relative expansion or folding. At the same time, the side shell 24 can clamp the electronic device 10 in the opposite direction through the accommodating space surrounded by the side shell and the bottom shell, so that the electronic device 10 is not easy to be separated from the protective shell 20 when the electronic device 10 is accommodated in the protective shell 20.

[0033] In some other embodiments, the protective shell 20 can also not be provided with the side shell 24. For example, the first bottom shell 231 and the first shell body 111 can be connected by adhesion or magnetic connection, the second bottom shell 232 and the second shell body 112 can be connected in the same way as the first shell body 111 and the first bottom shell 231, and the third bottom shell 233 and the third shell body 113 can also be connected in the same way. The protective shell 20 including only the bottom shell 23 can make the electronic device assembly 1 have a better holding feeling and be thinner and lighter.

[0034] When the protective shell 20 contains the electronic device 10, the second display screen 13 can be blocked. Therefore, in the present embodiment, the first bottom shell 231 corresponding to the first shell body 111 can also be provided with an exposure window 2311. The exposure window 2311 is used for exposing the second display screen 13. Specifically, the size of the exposure window 2311 can be greater than or equal to the area of the second display screen 13, so as to avoid blocking the picture displayed by the second display screen 13. In some embodiments, the first bottom shell 231 can also be provided with a camera window 2312 for exposing the rear camera 14.

[0035] In the present embodiment, the protective shell 20 can be made of hard material to better protect the electronic device 10. However, if the first bottom shell 231, the second bottom shell 232 and the third bottom shell 233 are connected by hard connection or one-piece forming, the first shell body 111, the second shell body 112 and the third shell body 113 can not be conveniently unfolded or folded relative to each other. Therefore, in the present embodiment, please refer to Figure 5 , the protective shell 20 can also include a first bending member 25 and a second bending member 26. Specifically, the first bottom shell 231 and the second bottom shell 232 are connected by the first bending member 25, and the second bottom shell 232 and the third bottom shell 233 are connected by the second bending member 26. It can be understood that the first bending member 25 can be arranged corresponding to the position of the first rotating connecting member 114, and the second bending member 26 can also correspond to the position of the second rotating connecting member 115. For example, the first bending member 25 and the second bending member 26 can be made of a material with elasticity, such as silicone or the like. During the unfolding or folding of the first bottom shell 231, the second bottom shell 232 and the third bottom shell 233 relative to each other, the first bending member 25 always adheres to the first rotating connecting member 114, and the second bending member 26 always adheres to the second rotating connecting member 115. In some other embodiments, the first bending member 25 and the second bending member 26 can also be a combined structure composed of multiple hinges.

[0036] Please refer toFigure 6 The first end 21 and the second end 22 are connected by a connecting mechanism, so that the electronic device assembly 1 forms a closed ring structure, as shown in Figure 7 The connecting mechanism can be a detachable connecting mechanism, which facilitates the user to wear or remove the electronic device 10. Specifically, the connecting mechanism includes a first connecting part 271 arranged on the first end 21 and a second connecting part 272 arranged on the second end 22, and the first connecting part 271 and the second connecting part 272 are detachably connected. The first connecting part 271 and the second connecting part 272 can be connected in a clamping manner. For example, the first connecting part 271 can be a male buckle, and the second connecting part 272 can be a female buckle corresponding to the male buckle. Through the cooperation between the male buckle and the female buckle, the first connecting part 271 and the second connecting part 272 can be detachably connected. In other embodiments, the first connecting part 271 and the second connecting part 272 can also be connected by adhesion, for example, the first connecting part 271 and the second connecting part 272 can be two sides of a magic tape respectively, and through adhesion, the first connecting part 271 and the second connecting part 272 can also be detachably connected. In some embodiments, the first connecting part 271 and the second connecting part 272 can also be connected by magnetism. For example, the first connecting part 271 and the second connecting part 272 can be respectively provided with magnets with opposite polarities, and when the first connecting part 271 and the second connecting part 272 are close to each other, the first connecting part 271 and the second connecting part 272 are connected by the magnetic force between the magnets.

[0037] The electronic device assembly 1 provided in the present application can be relatively unfolded or folded, so that the electronic device 10 has different use modes, such as being placed on a table after being folded, and at the same time, the bendable protective shell 20 is arranged to form an accommodation space. When the electronic device 10 is accommodated in the accommodation space, the first end 21 and the second end 22 of the protective shell 20 are bent to connect, so that the electronic device assembly 1 can be worn on the wrist of the user, which is convenient for carrying and also has a more abundant use experience.

[0038] The electronic device 10 in the present application can be a mobile phone or a smart phone (for example, an iPhone TM-based phone, an Android TM-based phone), a portable game device (for example, Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop computer, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices, and the like, such as a watch, a headset, a pendant, an earphone, and the like, and can also be other wearable devices (for example, a head-mounted device (HMD) such as electronic glasses, electronic clothes, an electronic bracelet, an electronic necklace, an electronic tattoo, an electronic device 10, or a smart watch).

[0039] The electronic device 10 can also be any one of a plurality of electronic devices 10, including but not limited to a cellular phone, a smart phone, other wireless communication devices, a personal digital assistant, an audio player, other media players, a music recorder, a video recorder, a camera, other media recorders, a radio, a medical device, a vehicle transportation instrument, a calculator, a programmable remote controller, a pager, a laptop computer, a desktop computer, a printer, a netbook, a personal digital assistant (PDA), a portable multimedia player (PMP), a moving picture experts group (MPEG-1 or MPEG-2) audio layer 3 (MP3) player, a portable medical device, and a digital camera, and combinations thereof.

[0040] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
