Description

Technical Field

[0001] The present application relates to the technical field of motherboard brackets, and in particular to a motherboard bracket assembly and a foldable electronic device. Background Art

[0002] With the advancement of science and technology, electronic devices have developed rapidly, especially foldable electronic devices (for example, foldable screen mobile phones) are very popular. Foldable electronic devices usually include two parts that can rotate around an axis. For example, in a foldable screen mobile phone, the first screen or the second screen rotates around an axis to realize the unfolded state or folded state of the mobile phone. Among them, when the mobile phone is in the folded state, a pop-up mechanism needs to be engaged with an opening on the edge of one of the screens to keep the two screens of the mobile phone in a folded state. When the mobile phone changes from a folded state to an unfolded state, the user usually needs to press the switch of the spring mechanism to unlock the engagement between the spring mechanism and the opening to realize the unfolding of the two screens.

[0003] However, in some implementations, the pop-up mechanism is an independent device from the motherboard bracket. Usually, after the pop-up mechanism is assembled, it is fixed to the motherboard bracket to obtain a motherboard bracket assembly. The current motherboard bracket is divided into two parts. The pop-up mechanism is installed at the position where the two parts are connected as a structure to connect the two parts. After the installation is completed, the motherboard bracket assembly is implanted as a whole into the whole machine. The motherboard bracket assembly of this structure has low overall strength, a large number of parts, and is complicated to disassemble, assemble and repair, and has a certain degree of installation difficulty.

[0053] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0054] To facilitate the understanding of the technical solution of the present application, the technical problem to be solved by the present application is first explained.

[0055] In some embodiments, the mainboard support and the pop-up mechanism of the foldable electronic device are two independent components. The mainboard support is divided into two parts: the mainboard support lower part and the mainboard support lower part. The structure of the pop-up mechanism includes a button, a sliding tongue baffle, a sliding tongue spring, a sliding tongue, a pop-up mechanism body, a base, and a locking screw. During installation, the button, the sliding tongue baffle, the sliding tongue spring, and the sliding tongue are first installed on the pop-up mechanism body, and then the bottom plate is installed, and these components are locked on the pop-up mechanism body through the locking screw through the bottom plate. After the pop-up mechanism is assembled, a part of the pop-up mechanism is fixedly connected to the lower half of the mainboard support, and the other part is fixedly connected to the lower half of the mainboard support. Finally, the mainboard support assembly is assembled.

[0056] The above-mentioned motherboard bracket assembly has a large number of structural parts, and is complex to disassemble, assemble and repair, and has a certain degree of difficulty in installation. In addition, in order to maintain the appearance of the motherboard bracket assembly, the surface needs to be kept level without protrusions. Therefore, the part where the motherboard bracket overlaps with the ejection mechanism needs to be thinned, which affects the overall strength of the motherboard bracket, and further affects the strength of the entire motherboard bracket assembly, resulting in reduced product quality and reduced user experience.

[0057] Based on the above technical problems, the embodiment of the present application provides a motherboard bracket assembly, the motherboard bracket is integrally formed, and the elastic mechanism is no longer an independent component, but the motherboard bracket is taken as a part of itself, so there is no need to design the motherboard bracket to be thinned. Not only can the number of overall parts be reduced, but the strength of the motherboard bracket is high, which can effectively improve the overall strength of the motherboard bracket assembly, improve product quality, and thus improve user experience.

[0058] The following is a detailed description of the overall foldable electronic device according to an embodiment of the present application with reference to the accompanying drawings.

[0059] An embodiment of the present application provides a foldable electronic device, which may be, but is not limited to, a foldable mobile phone, a tablet personal computer, an e-book reader, a laptop computer, a personal digital assistant (PDA), a personal computer, a notebook computer, a foldable display, a vehicle-mounted device, a wearable device (such as a watch), a box, and other foldable devices that need to be opened and closed.

[0060] The following takes a foldable mobile phone as an example to explain the structure of the foldable mobile phone.

[0061] See also Figure 1 , Figure 1 A schematic diagram of the process of the foldable mobile phone of the embodiment of the present application from the unfolded state to the folded state is shown. Figure 1 (a) is a schematic diagram of the structure of the foldable mobile phone in the embodiment of the present application in a fully unfolded state; Figure 1 (b) is a schematic diagram of the structure of the foldable mobile phone of the embodiment of the present application switching from the unfolded state to the folded state; Figure 1 (c) is a schematic diagram of the structure of the foldable mobile phone in the folded state according to an embodiment of the present application.

[0062] like Figure 1As shown, the foldable phone 1000 includes a first housing 100, a second housing 200 and a hinge device 300. The first housing 100 and the second housing 200 are rotatably connected via the hinge device 300. In different use states, the first housing 100 is rotated around the hinge device 300 to achieve different use states of the foldable phone 1000 formed with the second housing 200. Figure 1 As shown in (a) of FIG. 1 , when the first housing 100 rotates around the hinge device 300 to an angle of 0, the foldable mobile phone 1000 is in a fully unfolded use state (which can be understood as an unfolded state). Figure 1 As shown in (b), the first housing 100 rotates around the hinge device 300 toward the second housing 200. When the rotation angle is 180°, the following is obtained: Figure 1 The foldable mobile phone 1000 shown in (c) is in a completely closed state (which can be understood as a folded state).

[0063] It should be noted that the angles illustrated in the present application are allowed to have a slight deviation. For example, when the foldable mobile phone 1000 is in the open state, the open angle can be 180°, or about 180°, such as 170°, 175°, 185° or 190°, etc. Within the angle range of a certain amplitude different from 180°, the corresponding rotation angle can be understood to be 170°, 175°, 185° or 190°, etc.

[0064] Those skilled in the art can understand that the present application does not limit the specific structure of the foldable mobile phone 1000. For example, the foldable mobile phone 1000 can also include various electronic components. The first housing 100, the second housing 200 and the hinge device 300 together constitute the housing assembly of the foldable electronic device 1000 to provide protection and support for various electronic components and other structures. To facilitate understanding of the folding process and usage scenarios of the foldable mobile phone 1000, the following exemplary description of its possible structure is provided.

[0065] like Figure 1 As shown, in one embodiment, the foldable mobile phone further includes a display screen, which is laid on one side of the housing assembly. A portion of the display screen installed on the first housing 100 is a first screen 110, and a portion of the display screen installed on the second housing 200 is a second screen 210. Figure 1As shown in (b), driven by the hinge device 300, the first screen 110 rotates around the hinge device 300 with the first shell 100 to realize the unfolded state and the folded state with the second screen 210 on the second shell 200. In the embodiments of the present application, the display screen can be, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen or a quantum dot light-emitting diode (QLED) display screen, etc., and the present application does not limit this.

[0066] In one embodiment, the first housing 100 and the second housing 200 both have a storage space inside to accommodate some electronic components, wherein the electronic components include but are not limited to circuit boards, batteries, camera modules, microphones, speakers, etc., which are not limited in this application.

[0067] like Figure 1 As shown in (a) of FIG. 1 , a motherboard support assembly 400 is provided on the left side (left side in the figure) of the second screen 210, and the motherboard support assembly 400 can cover the components below it. For example, Figure 1 The camera module 500 shown in (a) of FIG. 4 is a mainboard support assembly 400. The mainboard support assembly 400 includes a pop-up mechanism 420. The tongue of the pop-up mechanism 420 is connected to the Figure 1 The opening 111 provided at the edge of the first screen 110 shown in (b) of the figure is used to cooperate with the opening 111 provided at the edge of the first screen 110 to realize the unfolding or folding of the foldable mobile phone 1000. Specifically, when the mobile phone 1000 is to be unfolded, the engagement with the first screen is released, and when the mobile phone 1000 is to be folded, the first screen is fixed by the engagement between the tongue and the opening. When the pop-up mechanism 420 is in the locked state (the tongue extends into the opening), as shown in FIG. Figure 1 As shown in (c), the first screen 110 and the second screen 210 are stacked and kept relatively fixed, that is, the foldable mobile phone 1000 is kept in a closed state by a pop-up mechanism to improve the stability of the foldable electronic device in the closed state. When the pop-up mechanism is in an unlocked state (the tongue leaves the opening), the first screen 110 and the second screen 210 can rotate relative to each other, as shown in FIG. Figure 1 The rotation state shown in (b) in the figure is used to realize the unfolded state of the foldable device 1000.

[0068] The specific structure of the mainboard bracket assembly 400 of the embodiment of the present application is described below in conjunction with the drawings.

[0069] In the figures in this article, the x direction is the length direction of the foldable mobile phone after unfolding, the y direction is the width direction of the foldable mobile phone after unfolding, and the z direction is the thickness direction of the foldable mobile phone.

[0070] Please refer to Figure 2 and Figure 3 , Figure 2 A three-dimensional structural schematic diagram of a mainboard bracket assembly according to an embodiment of the present application is shown. Figure 3 An exploded view of a mainboard bracket assembly according to an embodiment of the present application is shown.

[0071] like Figure 2 and Figure 3 As shown, the motherboard bracket assembly 400 includes a motherboard bracket 410 and an ejection mechanism 420. The motherboard bracket 410 is integrally formed, and compared with a motherboard bracket formed by splicing, the motherboard bracket 410 of the present application has higher strength, especially in the scenario where the ejection mechanism needs to be assembled.

[0072] The motherboard bracket 410 extends along a first direction of the foldable mobile phone, wherein the first direction can be understood as the direction of the y-axis. A first through hole 411 is provided on the motherboard bracket 410, and the first through hole 411 is used to install a pop-up mechanism to assemble into a motherboard bracket assembly 400 according to an embodiment of the present application.

[0073] According to the implementation mode of the present application, the mainboard bracket is integrally formed, and, in the Figure 1 The left side of the second screen 210 of the mobile phone shown in (a), (b), and (c) Figure 1 There is only one motherboard bracket in the space for mounting the motherboard bracket assembly 400 in (a)). In other embodiments, there may be multiple motherboards along the z-axis direction of the mobile phone 1000 device, but there is only one motherboard bracket on the plane where the motherboard bracket on which the pop-up mechanism according to the embodiment of the present application is installed is located.

[0074] Since there is only one mainboard bracket in the space for installing the mainboard bracket assembly 400, in the embodiment of the present application, the distance between at least one end of the mainboard bracket 410 and the adjacent edge of the folding mobile phone 1000 is set to be no greater than a preset distance. The preset distance can be designed according to actual needs, for example, 1 / 4, 1 / 5, 1 / 6 of the overall width of the mobile phone, etc. That is, the length arrangement of the mainboard bracket can be set according to the actual required length.

[0075] refer to Figure 4 , Figure 4 Schematic diagrams of the structure of the motherboard bracket 410 of different lengths and arrangement positions of the embodiment of the present application are shown. Figure 4 As shown in (a) of FIG. 1 , the length (length along the first direction) of the mainboard bracket 410 may be substantially equal to the width of the foldable mobile phone, or may be Figure 4 As shown in (b)-(d) in FIG. 1 , it is smaller than the width of the foldable mobile phone 1000. In addition, when the length of the motherboard bracket 410 is smaller than the width of the foldable mobile phone 1000, the position of the motherboard bracket 410 can be set as needed. Figure 4 As shown in (b) of FIG. 1 , the motherboard bracket 410 can be located in the middle of the width direction of the foldable mobile phone 1000, so that the distance between the lower end of the motherboard bracket and the adjacent edge (lower edge) of the mobile phone is not greater than a preset distance, and the distance between the upper end of the motherboard bracket and the adjacent edge (upper edge) of the mobile phone is not greater than a preset distance. Alternatively, as Figure 4 As shown in (c) of FIG. 1 , the motherboard support 410 can be extended along one side of the first direction from the lower edge (the lower edge in the figure) of the foldable mobile phone 1000 as a starting point, but the distance between the upper end of the motherboard support and the adjacent edge (upper edge) of the mobile phone is not greater than a preset distance. Figure 4 As shown in (d), the mainboard bracket 410 can be extended along the other side of the first direction from the upper edge of the foldable mobile phone 1000 (the upper edge in the figure) as the starting point, but the distance between the lower end of the mainboard bracket and the adjacent edge (lower edge) of the mobile phone is not greater than a preset distance.

[0076] In some embodiments, the motherboard bracket 410 can be shorter than the example in the figure, and the position can be in the middle or deviated from the middle, etc. In the embodiments of the present application, there is no limitation on the length and position of the motherboard bracket 410. The ratio of the motherboard bracket to the width of the mobile phone 1000 is within a preset range, and preferably, the ratio of the length of the mobile phone bracket to the width of the mobile phone 1000 is greater than 1 / 2.

[0077] In the embodiment of the present application, the motherboard bracket 410 can be used to cover various components inside the foldable mobile phone 1000. Figure 3 As shown, two mounting holes 412 are correspondingly provided on the mainboard bracket 410, and the mounting holes 412 can accommodate a camera, and can also cover a portion of a battery, or a mainboard, or components such as a speaker and a microphone. This application is not limited to this. In some embodiments, the mainboard bracket 410 can be used to cover the components inside the folding mobile phone 1000, so that the projections of the components installed at the corresponding positions of the mobile phone 1000 on the plane where the mainboard bracket is located are all within the range covered by the mainboard bracket 410.

[0078] In some embodiments, the number of mounting holes 412 may be 1, 3, or more, and may be set according to actual needs. In the embodiments of the present application, the number of mounting holes is not limited.

[0079] In addition, in some scenarios, in order to keep the appearance of the foldable phone more beautiful, it is also necessary to decorate the side of the motherboard bracket facing the first screen.

[0080] like Figure 3 As shown, a decorative plate 413 is provided on the mainboard bracket 410, and the decorative plate 413 extends along the first direction of the folding mobile phone 1000. The decorative plate 413 is connected to the mainboard bracket 410, and the plane where the decorative plate 413 is located forms an angle with the plane where the mainboard bracket 410 is located. The angle can be 90°, or can be greater than 90°, or slightly less than 90°, etc. The decorative plate 413 is provided with a second through hole 413a, and the sliding tongue component 422 extends out of the second through hole 413a under the drive of the button 423, and is in contact with the opening (such as Figure 1 The pop-up mechanism 420 is inserted into the opening shown in (b) of FIG. 1 to achieve the locking state of the foldable mobile phone 1000 by the pop-up mechanism 420. In some embodiments, the decorative plate 413 and the mainboard bracket 410 are integrally formed, which can enhance the overall aesthetics and facilitate manufacturing.

[0081] like Figure 2 and Figure 3 As shown, the ejection mechanism 420 includes an ejection component 421, a sliding tongue component 422 and a button 423. The sliding tongue component 422 is disposed on the first side ( Figure 2 The front end of the sliding tongue assembly 422 is along the second direction and toward the direction away from the side of the pop-up assembly 421 ( Figure 2 The “leaving” here means that the end of the sliding tongue component 422 for cooperating with the opening is away from the pop-up component. The pop-up component 421 is located on the same side of the mainboard bracket 410 as the sliding tongue component 422 and is connected to the sliding tongue component 422 to control the front end of the sliding tongue component 422 to move along one side of the second direction so that the sliding tongue component 422 is used to mate with the opening at the edge of the first screen of the foldable mobile phone (such as Figure 1 The foldable mobile phone 1000 is matched with the opening in the middle, that is, one end of the sliding tongue assembly 422 extends into the opening to achieve the locked state of the foldable mobile phone 1000.

[0082] like Figure 2 and 3 As shown, a portion of the button 423 is disposed on a second side (ie, the second side) of the mainboard bracket 410 opposite to the first side. Figure 2 The other part passes through the first through hole 411 of the motherboard bracket 410 and is connected to the sliding tongue component 422. The button 423 is used to control the sliding tongue component 422 to move along the other side of the second direction, that is, to move in the opposite direction to the extending direction of the sliding tongue component 422, so as to separate the sliding tongue component 422 from the opening of the foldable mobile phone.

[0083] In the embodiments of the present application, Figure 2 and 3 As shown, the second direction can be perpendicular to the first direction, that is, the x-axis direction in the coordinate system, or can be the same as the axial direction of the rotating shaft of the folding mobile phone. In other embodiments, the second direction can also form an angle less than 90° or greater than 90° with the first direction. In actual design, the front end of the sliding tongue component 422 can extend out of the outer edge of the second through hole 413a of the decorative plate 413 and cooperate with the opening of the first screen to achieve a locked state or an unlocked state between the two screens of the folding mobile phone.

[0084] In the motherboard bracket assembly 400 of the above embodiment, since the supporting body of the pop-up mechanism 420 is the motherboard bracket 410, the pop-up mechanism 420 is no longer an independent component, and there is no need to set a separate supporting body for the pop-up mechanism 420. Therefore, the number of parts can be reduced, and the time for installing and removing parts can be effectively reduced, and the difficulty of installation is greatly reduced. In addition, there is no need to thin the position of the motherboard bracket 410 that overlaps with the pop-up mechanism, and the motherboard bracket 410 is integrally formed, which can greatly improve the strength and the overall strength of the product compared with the existing two-part bracket.

[0085] like Figure 3 As shown, the ejection mechanism 420 further includes a base 424, which is disposed on a side of the ejection assembly 421 away from the mainboard bracket 410 ( Figure 3 During installation, the ejection assembly 421 and the sliding tongue assembly 422 can be fixed to the mainboard bracket 410 by fasteners 425, such as screws. This ensures the overall firmness of the ejection mechanism 420 and the mainboard bracket 410.

[0086] like Figure 3 As shown, the mainboard bracket 410 is provided with a first positioning hole 414, and the base 424 is provided with a second positioning hole 424a corresponding to the first positioning hole 414. A positioning bolt, such as a bolt, passes through the first positioning hole 414 and the second positioning hole 424a, as well as a positioning hole (not shown) on the middle frame, thereby realizing the positioning of the pop-up mechanism 420. This structure can effectively avoid shaking or deviation at the pop-up mechanism 420 caused by manufacturing tolerance.

[0087] Combination Figure 3 And refer to Figure 5 , Figure 5 A schematic structural diagram of the sliding tongue assembly 422 according to an embodiment of the present application is shown.

[0088] like Figure 5 As shown, the sliding tongue assembly 422 of the embodiment of the present application includes a sliding tongue mounting portion 422a and a sliding tongue 422b. Among them, the sliding tongue mounting portion 422a and the button (such as Figure 3The sliding tongue 422b is fixedly connected to the sliding tongue mounting portion 422a, and the sliding tongue 422b is used to pass through the second through hole (such as Figure 3 The second through hole 413a in the first screen is formed, and the end of the sliding tongue 422b is aligned with the opening of the first screen ( Figure 1 The opening 111) shown in (b) in the figure matches so as to be able to penetrate into the opening or move out from the inside of the opening.

[0089] It should be noted that the shape of the sliding tongue assembly in the embodiment of the present application is not specifically limited, as long as it can fix the second screen when inserted into the opening, that is, the design of the opening and the sliding tongue assembly are matched.

[0090] Combination Figure 3 And refer to Figure 6 , Figure 6 The schematic diagram of the structure of the sliding tongue assembly 422 of the embodiment of the present application is shown as follows: Figure 6 It can also be understood as Figure 2 The structural diagram is obtained by turning the structure upside down and removing the base.

[0091] like Figure 3 and Figure 6 As shown, the pop-up assembly 421 includes a sliding tongue baffle 421a and an elastic member 421b. The sliding tongue baffle 421a is connected to the mainboard bracket 410. One end of the elastic member 421b abuts against the sliding tongue baffle 421a, and the other end abuts against one end of the sliding tongue mounting portion 422a. Figure 6 As shown, the elastic member can drive the sliding tongue 422b to extend out of the second through hole 413a along the second direction, so that a portion of the sliding tongue 422b is embedded in the opening corresponding to the first screen, so as to achieve a locked state between the two screens of the foldable mobile phone.

[0092] In some embodiments of the present application, the elastic member 421b is a cylindrical spring structure. In some embodiments, it can also be a spring mechanism, or a member having an elastic material, etc. The embodiments of the present application are not limited to this.

[0093] like Figure 3 As shown, the button includes a pressing portion 423a and a connecting column 423b. The first end of the connecting column 423b is connected to the pressing portion 423a, and the second end passes through the first through hole 411 on the mainboard bracket 410 and is connected to the sliding tongue mounting portion 422a. This structure is convenient for users to operate. The user can press the pressing portion 423a to retract the sliding tongue into the mainboard bracket 410, so that the opening is separated from the sliding tongue 422b.

[0094] The surface of the pressing portion may be a plane, or may have a concave or convex structure, which is not limited in the present application.

[0095] Combination Figure 6 , and refer to Figure 7a and 7a , Figure 7a A schematic diagram of the structure of the button 423 and the sliding tongue assembly 422 of the embodiment of the present application is shown at an angle. Figure 7b A structural schematic diagram showing the connection between the button 423 and the sliding tongue assembly 422 at another angle in an embodiment of the present application is shown.

[0096] like Figure 7a and Figure 7b As shown, at the second end adjacent to the connecting column 423b, the surface of the connecting column 423b is recessed inward to form a hook groove 423c. The direction of the opening end of the hook groove 423c is opposite to the direction of the sliding tongue 422b (see Figure 3 The direction of the sliding tongue, or the extension direction of the sliding tongue mentioned above). Figure 6 As shown, the sliding tongue mounting portion 422a is provided with an accommodation space a1, and a driving rod 422c is arranged in the accommodation space a1, and the driving rod 422c passes through the hook slot 423c and is connected to the sliding tongue mounting portion 422a, thereby realizing the connection between the button 423 and the sliding tongue assembly 422.

[0097] refer to Figure 8 , Figure 8 The schematic diagram of the structure of the button and the driving rod in the embodiment of the present application when they are connected under stress is shown. Figure 8 As shown, the side wall of the hook groove 423c includes a first surface c1, a second surface c2 and a third surface c3 which are connected in sequence. The first surface c1 is close to the second end of the connecting column 423b, and the second surface c2 is an arc surface, and the third surface c3 is an inclined surface. When no external force is applied, the surface of the driving rod 422c abuts against the second surface c2 and the third surface c3 of the hook groove 423c. When a downward force (corresponding to the third direction) is applied to the button 423, as the button 423 moves downward, the driving rod 422c moves upward relative to the button 423, that is, slides from the first position to the second position. Since the driving rod 422c is stationary in the vertical direction, the thrust applied to the third surface c3 is converted into a horizontal direction (parallel to the first direction) movement (such as Figure 8 The horizontal movement distance shown in the figure on the right side of the figure) is the same as the horizontal movement distance shown in the figure on the right side of the figure, and the movement direction is opposite to the direction of the sliding tongue, thereby driving the sliding tongue to retract into the inside of the motherboard bracket, separating the sliding tongue from the opening, and achieving unlocking.

[0098] In the above, when the driving rod 422c is moved horizontally by the third surface c3, the driving rod 422c compresses the spring. When the force applied to the button 423 is removed, the compressed spring drives the sliding tongue to extend from the second through hole, so that when the two screens of the folding mobile phone need to be in a folded state, the sliding tongue pops out and is aligned with the opening (such as Figure 1 The corresponding opening 111) in (b) is plugged in to achieve a locked state.

[0099] In the above embodiment, the locking state is achieved by plugging the sliding tongue and the opening as an example. In some embodiments, two buckle-fitting structures may also be used, and the embodiments of the present application are not limited to this.

[0100] like Figure 3 As shown, in some embodiments of the present application, the button further includes a positioning plate 423d, one end of the positioning plate 423d is connected to the pressing portion 423a, and the other end is a free end arranged toward the mainboard bracket 410. The mainboard bracket 410 is provided with a positioning groove 415, and the positioning groove 415 is used to accommodate the free end of the positioning plate 423d. When the button 423 is pressed downward, the free end of the positioning plate 423d will be inserted into the positioning groove 415, thereby limiting the shaking of the connecting column of the button 423 due to manufacturing tolerance.

[0101] According to the motherboard bracket assembly of the embodiment of the present application, the pop-up mechanism and the motherboard bracket are integrated into an integrated design, which simplifies the number of structural parts, facilitates the processing and manufacturing of parts, and reduces the cost of parts. The problem that the pop-up mechanism cannot be integrated with the motherboard bracket due to its large size is solved, and a design scheme in which the motherboard bracket and the pop-up mechanism are integrated is realized. In addition, the integrated design does not require the bracket to be thinned, which improves the overall strength of the motherboard bracket, thereby improving the quality of the final product for experience enhancement.
