Especially in the field of thin and light foldable phones, it is necessary not only to ensure the performance of the device, but also to achieve an extremely thin and light design. Due to its unique folding method, foldable phones have high requirements for space utilization, which poses a higher challenge to the design of the motherboard and its bracket. In a limited space, not only must the layout be reasonable and the effective connection of each component be ensured, but also the structural stability of the whole machine must be taken into account.

[0003] The traditional motherboard bracket design will expose some problems when facing the special requirements of folding mobile phones that have extremely high requirements for lightness and thinness. For example, due to the limitation of the thickness of the whole machine, the layout space of the board-to-board (BTB) connector on the motherboard is tight, and there will be problems with pressing when multiple BTB connectors are arranged side by side. For example, if the motherboard bracket has a large span, the BTB connector in the middle position is easy to loosen due to vibration and other reasons, affecting the service life and stability of the equipment. In addition, if there are grounding devices such as shrapnel or springs under the bracket, these devices should not be subjected to excessive pressure and are not suitable for fixing with the traditional z-direction bump design, which makes the motherboard bracket design face greater challenges.

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0046] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical problems to be solved by the embodiments of the present application are first described.

[0047] As the core component of electronic devices, the motherboard contains the circuits and interfaces required to form the basic functions of the system. Usually, there are multiple sub-circuit boards on the motherboard, which need to be connected together to form a complete control center. The board-to-board connector (BTB), referred to as the BTB connector, is a component used to provide electrical connection between two parallel or close sub-circuit boards (printed circuit boards). These BTB connectors need to be fixed with a bracket (motherboard bracket) to ensure the stability of the overall connection of the motherboard.

[0048] The technical problem to be solved by the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0049] It should be noted that in the various figures herein, the thickness direction of the mainboard bracket is the thickness direction of the mobile phone, corresponding to the z-axis direction in the coordinate system. The x-axis direction in the coordinate system can be the length direction of the mobile phone or the width direction of the mobile phone. The y-axis direction in the coordinate system can be the width direction of the mobile phone or the length direction of the mobile phone. The first direction mentioned in the embodiments of the present application corresponds to the z-axis direction (z-direction), and the second direction corresponds to the x-axis direction or the y-axis direction (y-direction). In some cases, the first direction may intersect with the second direction but not be perpendicular, and the present application does not limit this.

[0050] refer to Figure 1a and Figure 1b , Figure 1a A partial structural schematic diagram of the mainboard 10 in some embodiments is shown. Figure 1b Shows Figure 1a Schematic diagram of the partial structure after the main board 10 and the bracket 12 are assembled. Figure 1a As shown, a plurality of BTB connectors 11 may be provided on the mainboard 10. For example, three BTB connectors 11 are provided along the y-axis direction of the mainboard 10. These BTB connectors 11 connect the plurality of sub-circuit boards 13 together to achieve fixation and electrical connection between the plurality of sub-circuit boards 13. However, these BTB connectors 11 are easy to come loose, and therefore, these BTB connectors 11 need to be fixed. Figure 1b It is shown in Figure 1a The main board 10 is shown with the bracket 12 covering it. Figure 1b As shown, in the z-axis direction, the main board 10 and the bracket 12 are arranged in an overlapping manner. Figure 1a Each BTB connector 11 and the sub-circuit board 13 shown in FIG. 1 are covered by the bracket 12 and are not visible. The bracket 12 extends along the y-axis direction and spans across three BTB connectors (such as Figure 1aThe three BTB connectors 11 are confined between the mainboard 10 and the bracket 12. Both ends of the bracket 12 are connected and fixed to the mainboard 10, for example, by screws or plugging in a fixed groove, so that the three BTB connectors 11 are pressed on the mainboard 10.

[0051] Since the bracket 12 spans over more than two BTB connectors 11, in particular, Figure 1b The coverage shown is as follows Figure 1a When there are more than three BTB connectors 11 shown in the figure, the span of the bracket is large, so the pressure in the middle position of the bracket 12 is relatively weak, which will cause the BTB connector 11 in the middle or near the middle position to be subjected to a small pressing force, and it is easy to get loose. Therefore, a protrusion 12a facing the z-axis direction is set in the middle position of the bracket 12, and extends a certain length along the y-axis direction, and the protrusion 12a faces the direction of the mainboard 10. The BTB connector 11 in the middle position is pressed and fixed by the protrusion 12a, so as to improve the pressing force of the bracket 10 on the BTB connector 11, so as to better fix the BTB connector 11. However, due to the increasing requirements of foldable mobile phones for lightness and thinness, that is, the thickness in the z-axis direction is getting smaller and smaller, the space in the z-direction is very limited, and the design of the protrusion 12a needs to reserve a certain z-direction extension space, such as 0.05mm. However, the current ultra-thin design has no z-direction extension space for the protrusion 12a.

[0052] In other embodiments, a spring or spring for grounding is provided on the mainboard 10 between the two BTB connectors 11. These springs or springs have a certain elasticity and can adapt to slight physical deformation, thereby maintaining good contact pressure, but cannot be over-pressed, otherwise the spring will be damaged and cause poor contact, affecting the transmission of the mainboard signal. Therefore, this structure with springs or springs is not suitable for the raised pressing method.

[0053] refer to Figure 2 , Figure 2 Schematic diagrams of the structure of the mainboard 20 in other embodiments are shown. Figure 2 As shown, two BTB connectors 21 are provided on the mainboard 20, and a spring 22 is provided between the two BTB connectors 21. The spring or spring is used for grounding and cannot be over-pressurized. Figure 1b As shown, if the bracket 12 is set to have a protrusion 12a, overpressure on the spring 22 may occur and damage the spring 22. Therefore, it is not suitable to use the main board 20 with the spring 22. Figure 1b The bracket 12 structure shown in FIG. 1 is used to fix the BTB connector 21 .

[0054] In response to the technical problems mentioned above, the present application provides a motherboard bracket, which is suitable for thin and light folding mobile phones. By adding a snap-fit ​​structure and a support structure to the side of the bracket body to limit the distance between the bracket and the motherboard, on the one hand, it can cooperate with the press-fit structure on the motherboard to limit the space of the bracket in the z-axis direction, and can better fix the BTB connector located in the middle position. On the other hand, by limiting the distance between the bracket and the motherboard through the support structure, it is possible to avoid the distance between the bracket and the motherboard being too small to damage the spring or shrapnel (such as Figure 2 The spring 22 in the mainboard bracket effectively solves the problems of difficulty in pressing multiple BTB connectors 11 side by side and loosening of the BTB connector in the middle without increasing the thickness of the whole machine. In addition, it can also better protect pressure-sensitive components such as springs or shrapnel.

[0055] The mainboard bracket of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0056] The motherboard bracket of the embodiment of the present application can be applied to the motherboard of various electronic devices. Among them, the electronic device can be but not limited to a straight-screen mobile phone, a folding screen mobile phone, a tablet computer, an e-book reader, a laptop computer, a personal digital assistant (PDA), a notebook computer, etc. In the following embodiments, the motherboard bracket used in a folding mobile phone is used as an example for description.

[0057] In order to facilitate understanding of the overall structure of the bracket structure, the overall structure after the mainboard bracket is connected to the mainboard is first described.

[0058] refer to Figure 3 , Figure 3 FIG. 2 shows a schematic diagram of the structure of the motherboard 200 and the motherboard bracket 100 after being assembled according to an embodiment of the present application. Figure 3 As shown, in the z-axis direction, the motherboard bracket 100 is superimposed on the motherboard 200, and a plurality of BTB connectors 230 are arranged between the motherboard bracket 100 and the motherboard 200 (due to Figure 3 The BTB connector 230 in the embodiment is covered by the bracket body, and is therefore shown here with a dotted line. Figure 2 BTB connector 21 or Figure 1a The motherboard bracket 100 and the motherboard 200 are fixed by fasteners 300, and the positions where these fasteners 300 are fixed need to avoid places where there are BTB connectors 230 or springs 220 and other components. Figure 3 (See also Figure 1a or Figure 2When there are multiple BTB connectors 230 arranged side by side as described in the embodiment of the present invention, or when there are both BTB connectors 230 arranged side by side and springs 220, in the case where the motherboard bracket 100 has a large span, a buckle assembly 110 is provided on the edge of the bracket body 120 at a suitable position to limit the space between the motherboard 200 and the motherboard bracket 100 at the corresponding position, so as to prevent the BTB connector 230 at the middle position from being loosened. Figure 1a or Figure 2 In the case of, the suitable position is, for example, the midpoint of the bracket 12, that is, the midpoint of the length of the BTB connectors 230 when they are arranged side by side. The buckle assembly 110 is engaged with the pressing piece 210 on the mainboard 200, that is, the pressing piece 210 limits the movement of the buckle assembly 110 in the z-axis direction, thereby limiting the distance between the mainboard bracket 100 and the mainboard 200, and can effectively press and fix the device, so that the mainboard bracket 100 effectively solves the problem of the BTB connector 230 located in the middle position being loosened due to the side-by-side arrangement of multiple BTB connectors 230 without increasing the thickness of the whole machine. In addition, the buckle assembly 110 itself has a supporting function, which can better protect the spring 220 or the spring and other devices.

[0059] The motherboard bracket 100 is described in detail below in conjunction with the accompanying drawings. In the following embodiments, the local structure of the motherboard bracket 100 is taken as an example for description. The undescribed parts can refer to the structure of the motherboard bracket in the prior art and will not be described in detail here.

[0060] refer to Figure 4a-4c , Figure 4a The schematic diagram of the partial structure after the mainboard bracket 100 and the mainboard 200 are assembled in the embodiment of the present application is shown. Figure 4b FIG. 1 shows a partial structural diagram of a mainboard bracket 100 according to an embodiment of the present application. Figure 4c for Figure 4a Schematic diagram of the cross-sectional structure of AA.

[0061] Figure 4a is Figure 3 Based on the above, the focus is on the partial structural diagram after the motherboard bracket 100 covers the parallel BTB connectors. Figure 4a As shown, the motherboard bracket 100 includes a bracket body 120 and a buckle assembly 110. The buckle assembly 110 is engaged with a pressing piece 210 provided on the motherboard.

[0062] Figure 4b is based on Figure 4a FIG. 1 is a partial enlarged view of the support body 120. Figure 4b As shown, a mounting portion 121 is provided on the bracket body 120. A through hole 121a is provided on the mounting portion 121, and the through hole 121a penetrates the upper surface of the mounting portion 121 (corresponding to the first surface, which refers to the Figure 4bAs shown, the side surface exposed to the outside is opposite to the side surface of the mounting portion 121 facing the circuit board) and the lower surface (corresponding to the second surface, which refers to the side opposite to the first surface, or the surface of the side adjacent to the main board). The upper surface of the mounting portion 121 faces downward (as shown in FIG. Figure 4b The mounting portion 121 is further provided with a hole structure 122. The matching relationship between the through hole 121a, the first groove 121b and the hole structure 122 and other components will be described in detail later.

[0063] Figure 4c yes Figure 4a The cross-sectional structure diagram of AA is as follows: Figure 4c As shown, the snap assembly 110 includes a snap-fit ​​portion 111, a supporting portion 112 and a connecting member 113. The snap-fit ​​portion 111 is arranged on the upper surface of the mounting portion 121 and is snap-fitted with the pressing member 210 to limit the pressing of the bracket body 120 on the device arranged on the mainboard 200 in the z-axis direction, so that the mainboard bracket 100 effectively solves the problem of loosening of the BTB connector in the middle position due to the side-by-side pressing of multiple BTB connectors without increasing the thickness of the whole machine.

[0064] like Figure 4c As shown, the support portion 112 is disposed on the lower surface of the mounting portion 121 (eg Figure 4c The support portion 112 is located below the bracket body 120 in the bracket body 120). One end of the support portion 112 abuts against the lower surface of the bracket body 120, and the other end extends along the z-axis direction (first direction) to a preset length and points in the direction of the mainboard 200. When the bracket 100 together with the snap-fit ​​portion 110 are installed together with the mainboard 200, the other end of the support portion 112 can abut against the mainboard 200, that is, a support structure is added between the mainboard 200 and the bracket body 120 to ensure the distance d between the bracket body 120 and the mainboard 200 (the distance d can be greater than or equal to the preset length) to avoid the spring or shrapnel and other devices arranged between the mainboard 200 and the mainboard bracket 100 from being squeezed and damaged. The shape of the support portion 112 can be in any form to adapt to the assembly environment of the mainboard 200, as long as it includes at least one end abutting against the bracket body 120 and the other end being able to abut against the support structure of the mainboard 200. Figure 4c In the embodiment shown, the support portion 112 is not a regular table shape, but an irregular three-dimensional shape on the side close to the mainboard 200 to avoid the components on the mainboard 200. Figure 4c As shown in the cross-sectional view taken along line AA of FIG. 1 , the cross-sectional view of the support portion 112 at this position is a trapezoid, while the portion outside this cross-sectional view may be a regular cylinder or a cube.

[0065] In order to ensure the firmness of the connection between the engaging portion 111 and the bracket body 120, the Figure 4c The connecting member 113 shown connects the engaging portion 111 and the supporting portion 112. The connecting member 113 can be disposed at an end of the bracket body 120 (eg, Figure 4c The right end of the bracket body 120 in the bracket body 120 is connected to the clamping part 111 and the supporting part 112. The connecting member 113 can also pass through the through hole (such as Figure 4b 121a) is connected to the locking portions 111 and the supporting portions 112 on both sides (this structure will be described in detail in the following embodiments).

[0066] It should be noted that the specific parameter value of the preset length of the support portion extending along the z-axis can be set according to actual needs. For example, it can be determined in combination with the thickness of the connector on the z-axis. The embodiment of the present application does not limit this.

[0067] In some embodiments, Figure 4b and Figure 4c As shown, the upper surface of the mounting portion 121 faces downward (as shown in FIG. Figure 4b The first groove 121b is formed by recessing the lower surface of the first surface of the first groove 121b. The first groove 121b can be set so that one side of the engaging portion 111 is just embedded in the first groove 121b (such as Figure 4c In the embodiment, the engaging portion 111 and the second groove are fitted in an approximately Z-shaped structure), thereby improving the stability of the connection between the engaging portion 111 and the mounting portion 121.

[0068] The above only illustrates the situation where there is only one buckle assembly 110 on the bracket body 120. In some embodiments, a plurality of buckle assemblies 110 may be provided on the bracket body 120 as required.

[0069] refer to Figure 4d , Figure 4d Another partial structural schematic diagram of the mainboard and mainboard bracket of the embodiment of the present application is shown. Figure 4d As shown, within the span of the bracket body 120, that is, within the range of the length of the bracket body 120 in the y-axis direction, multiple snap assemblies 110 can be arranged to cooperate with the pressing piece 210. For example, a snap assembly 110 can be arranged in the middle of the span, or snap assemblies 110 can be added on both sides of the middle position on the same side, or snap assemblies 110 can be arranged on the opposite side, and correspondingly, pressing pieces 210 are also arranged, so that the bracket body is pressed from multiple positions, and a uniform support is formed, so as to better fix the BTB connector and better protect the spring and other components. Among them, the pressing piece 210 can be fixed on the main board 200 by welding, or it can be fixed by gluing.

[0070] In some embodiments, the snap assembly 110 is disposed on the edge of the outline of the bracket body 120 , which facilitates installation and is not easily restricted by the position of components on the mainboard 200 .

[0071] In some embodiments of the present application, the material of the buckle assembly 110 can be selected from elastic materials, such as silicone, to ensure that the mainboard bracket 100 has good elasticity and stability.

[0072] In some embodiments, although from the perspective of the functions realized, the snap assembly 110 as described above includes the snap-fit ​​portion 111, the support portion 112, and the connector 113 which can be realized as independent components and connected together during assembly. However, in some embodiments, the snap-fit ​​portion 111, the support portion 112, and the connector 113 included in the snap-fit ​​assembly 110 can be integrally formed, for example, by injection molding, which is easy to manufacture, and the overall structural connection is stable. In other embodiments, the snap-fit ​​portion 111 and the support portion 112 included in the snap-fit ​​assembly 110 are integrally formed. During installation, they are buckled onto the mounting portion of the mainboard bracket, and then reinforced by the connector 113.

[0073] In some embodiments, the bracket body 120 can be made of a lightweight and high-strength material, such as a magnesium alloy, which can maintain the strength of the mainboard bracket 100 while having a lightweight effect.

[0074] Combined with the above mentioned Figure 4b , and refer to Figure 5a and Figure 5b The structure of the bayonet assembly 110 and the mounting portion 121 being assembled in cooperation with each other is further described and observed from different angles.

[0075] Figure 4b The structure of the bracket body 120 is observed from a top view. Figure 5a A schematic structural diagram of the buckle assembly 110 of an embodiment of the present application at an angle (for example, looking down at the side front of the bayonet assembly from the front at 45 degrees) is shown. Figure 5b A schematic structural diagram of the buckle assembly 110 of an embodiment of the present application at another angle (for example, looking down at the lateral back of the buckle assembly from the rear side at 30 degrees) is shown.

[0076] like Figure 5a As shown, the engaging portion 111 of the buckle assembly 110 is provided with a second groove 111a, and the second groove 111a is connected to the pressing piece (refer to Figure 4a The shapes of the ends of the pressing piece 210 are matched so that the ends of the pressing piece can be embedded in the second groove 111a, thereby improving the stability of the connection between the pressing piece 210 and the clamping portion 111.

[0077] like Figure 5bAs shown, a connecting member 113 is provided between the engaging portion 111 and the supporting portion 112. The connecting member 113 passes through the through hole (such as Figure 4b The through hole 121a shown in the figure has one end connected to the locking portion 111 disposed on the upper surface of the mounting portion 121, and the other end connected to the supporting portion 112 disposed on the lower surface of the mounting portion 121, so that the stability of the connection between the buckle assembly 110 and the bracket body can be further improved.
