Description

Technical Field

[0001] The present invention relates to the technical field of motherboard installation, and specifically to a housing structure for a mobile phone motherboard that is convenient for installation. Background Art

[0002] As the core component of a mobile phone, the motherboard of a senior mobile phone carries all the basic functions of the mobile phone's operation. It integrates a variety of electronic components and realizes signal transmission, processing, and control through complex circuit connections. The motherboard of a senior mobile phone mainly consists of the following parts: Chipset: including a processor (CPU), baseband chip, etc., responsible for processing data and signals; Capacitors and inductors: used for storing electrical energy and filtering to ensure the stable operation of the circuit; Transistors: acting as electronic switches to control the on and off of current and realize logical operations; Resistors: adjusting the current magnitude to protect the circuit from overcurrent damage; Connectors: used to connect the motherboard to other components, such as the screen, battery, camera, etc.; Other auxiliary components: such as diodes, transistor arrays, integrated circuits, etc., together constituting a complete circuit system;

[0003] When installing a mobile phone motherboard, first, the motherboard needs to be gently placed on the installation position to ensure that all interfaces and screw holes are aligned. Subsequently, the motherboard is fixed by using screws. Then, cables such as the screen, camera, and speaker are respectively connected to the corresponding interfaces on the motherboard, ensuring that each cable is inserted tightly to avoid loosening. After ensuring that all connections are correct, a power-on test is performed to check whether the mobile phone can work properly. During the installation process of the motherboard, the reserved installation holes on the motherboard need to be aligned with the screw holes on the housing. After alignment, the staff installs the screws in sequence. However, when installing the screws, since the installation of the screws requires holding the motherboard with one hand and turning the screw with the other hand, and the space inside the housing is relatively narrow (usually the space inside the housing is slightly larger than the size of the motherboard), thus, staff with relatively less installation experience are prone to applying excessive force to the motherboard during the installation process, resulting in displacement. That is, the screw holes of the remaining reserved holes except the hole where the screw is being installed may become misaligned, so the position of the motherboard may need to be adjusted multiple times during the installation process, affecting the installation efficiency of the motherboard. For this reason, we propose a housing structure for a mobile phone motherboard that is convenient for installation. Summary of the Invention

[0004] The purpose of the present invention is to provide a housing structure for a mobile phone motherboard that is convenient for installation, so as to solve the problems raised in the above background art.

The pressing plate includes a supporting area and an acting area. The connecting part is used to support the pressing plate. A plurality of force-receiving rod frames are fixedly installed on the outer wall of the supporting area, and a plurality of acting rod frames are fixedly installed on the inner wall of the moving frame. When the acting rod frame moves, it applies a force to the force-receiving rod frame to adjust the angle of the pressing plate. A plurality of slots are provided on each side wall of the plastic frame.

[0006] Preferably, the connecting part includes an installation sleeve fixedly installed on the inner wall of the top of the plastic frame, a limiting shaft body rotatably connected to the inner wall of the installation sleeve is installed on the installation sleeve, and one end of the limiting shaft body is rotatably connected to the inner wall of the bottom of the plastic frame. The supporting area is installed on the limiting shaft body and is slidably connected to the outer wall of the limiting shaft body.

[0007] Preferably, a rolling sphere movably connected to the inner wall of the supporting area is installed on the supporting area, and an arc-shaped convex block is fixedly installed on the inner wall of the moving frame. When the acting area rotates to the outside of the plastic frame through the slot, the rolling sphere is located on the movement track of the arc-shaped convex block.

[0008] Preferably, a first torsion spring is connected between the installation sleeve and the limiting shaft body, and a return spring is fixedly installed on the inner wall of the bottom of the plastic frame. The return spring is in contact with the supporting area.

[0009] Preferably, circular sleeves are fixedly installed at two corners of the plastic frame, a double-layer winding sleeve rotatably connected to the inner wall of the circular sleeve is installed inside the circular sleeve, and two groups of rope bodies connected to the ends of the moving frame are wound in parallel on the double-layer winding sleeve. The extension lines of the center points of the ends of the two groups of rope bodies are perpendicular to each other. A constant force spring is connected between the moving frame connected to the rope body and the inner wall of the plastic frame.

[0010] Preferably, a moving shaft body slidably connected to the inner wall of the double-layer winding sleeve is also installed on the double-layer winding sleeve. One end of the moving shaft body penetrates through the inner wall of the top of the circular sleeve and extends to the outside. A cavity is provided at the bottom of the circular sleeve, and the other end of the moving shaft body is located inside the cavity. An expansion shaft body is fixedly installed in the area where the moving shaft body is located inside the cavity.

[0011] Preferably, a plurality of guiding blocks are fixedly installed on the inner wall of the cavity, and the guiding blocks are evenly distributed at equal angles in a circular shape on the inner wall of the cavity. One side of the guiding block is an inclined surface and the other side is a right-angle surface, and the guiding block is located on the movement track of the telescopic shaft body.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The present invention can effectively pre-fix the main board body by using the pressing plate and the flexible rubber pad thereon. By rotating the moving shaft body, the double-layer winding sleeve rotates, so that the rope body can control the position adjustment of the moving frame within the plastic frame, so that the force-bearing rod frame drives the pressing plate to adjust the angle under the action of the acting rod frame, and the flexible rubber pad on the pressing plate fixes the main board body by using the arc-shaped convex block and the rolling sphere. On the one hand, it is convenient for the operator to install the main board body, and on the other hand, the fixing strength of the main board body can be effectively increased by the flexible rubber pad, avoiding the loosening of the main board body during the use by the user.

[0017] The present invention can effectively limit the rotation direction of the telescopic shaft body through the guiding block, avoiding the loosening of the flexible rubber pad during the pre-fixing of the main board body. And under the action of the vertical sliding rail and the circular track, the moving shaft body can be quickly reset, effectively releasing the pre-fixing of the flexible rubber pad on the main board body, so that the operator can disassemble the main board body. Furthermore, under the action of the guiding block, the double-layer winding sleeve can be limited, facilitating the operator to adjust the misaligned main board body at any time during the installation process, so as to improve the installation quality and speed of the main board body.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-12 , the present invention provides a technical solution: a housing structure of a mobile phone motherboard that is easy to install. The present invention makes corresponding improvements to the technical problems in the background art to facilitate the installation of the motherboard inside the housing and improve the working efficiency of installing the motherboard inside the housing. It includes an upper cover 1, a lower cover 2 connected to the upper cover 1 by screws, and a motherboard body 3 located inside the lower cover 2. Among them, the motherboard body 3 is fixed to the lower cover 2 by screws, and electrical units such as a screen and buttons are also pasted on the motherboard body 3. A plastic frame 4 adapted to the inner wall of the lower cover 2 is fixedly installed inside the lower cover 2, and a plurality of interconnected moving frames 5 are installed inside each side wall of the plastic frame 4. The plastic frame 4 is square-shaped, and the moving frame 5 is slidably connected to the side wall of the plastic frame 4. Combining with the attached Figure 2 and the attached Figure 3 as shown, and circular sleeves 8 are fixedly installed at two of the corners of the plastic frame 4. A constant force spring 53 is connected between the moving frame 5 close to the circular sleeve 8 and the inner wall of each side wall of the plastic frame 4. And a double-layer winding sleeve 81 rotatably connected to its inner wall is installed inside the circular sleeve 8, and two groups of rope bodies 82 connected to the ends of the moving frame 5 are parallelly wound on the double-layer winding sleeve 81. Combining with the attached Figure 9 as shown, the extension lines of the central points of the ends of the two groups of rope bodies 82 are perpendicular. Furthermore, the two groups of rope bodies 82 are connected to the moving frames 5 inside the two side walls of the plastic frame 4. When the double-layer winding sleeve 81 rotates clockwise (forward), then under the action of the rope body 82, the moving frame 5 will move towards the direction of the circular sleeve 8, and the constant force spring 53 is in a compressed state;

[0033] And a plurality of connecting parts 6 are also provided inside each side wall of the plastic frame 4. A pressing plate 7 for pre-fixing the motherboard body 3 is provided on each connecting part 6, and the pressing plate 7 corresponds to the moving frame 5 one by one. The pressing plate 7 includes a supporting area 71 and an acting area 72. Among them, the connecting part 6 is used to support the pressing plate 7. Combining with the attached Figure 4 , the attached Figure 5 and the attached Figure 8 as shown, a plurality of flexible rubber pads 74 are fixedly installed at the end of the acting area 72. A plurality of heat dissipation holes 75 are opened on each flexible rubber pad 74. The flexible rubber pad 74 can contact the motherboard body 3 to play a pre-fixing role, and a plurality of slots 41 are provided on each side wall of the plastic frame 4. Combining with the attached Figure 4As shown, if the pressing plate 7 located on the connecting part 6 is adjusted in angle, it will move from the inside of the plastic frame 4 to the outside through the slot 41 and be located at the corresponding position of the main board body 3, which can effectively pre-fix the main board. A plurality of force-bearing rod frames 73 are fixedly installed on the outer wall of the supporting area 71, and a plurality of acting rod frames 51 are fixedly installed on the inner wall of the moving frame 5. During the movement of the acting rod frame 51, a force is applied to the force-bearing rod frame 73 to adjust the angle of the pressing plate 7.

[0034] As a further limitation in the present invention, the connecting part 6 includes an installation sleeve 61 fixedly installed on the inner wall of the top of the plastic frame 4, and a limiting shaft body 62 rotatably connected to its inner wall is installed on the installation sleeve 61. One end of the limiting shaft body 62 is rotatably connected to the inner wall of the bottom of the plastic frame 4. The supporting area 71 is installed on the limiting shaft body 62 and is slidably connected to the outer wall of the limiting shaft body 62. Combining with the attached Figure 4 and the attached Figure 6 As shown, when the double-layer winding sleeve 81 rotates clockwise, under the action of the rope body 82, the moving frame 5 moves in a directional manner towards the circular sleeve 8 inside the plastic frame 4. During this process, the moving frame 5 squeezes the constant force spring 53. During the movement of the moving frame 5, a plurality of acting rod frames 51 on its inner wall move synchronously with it. During the movement of the acting rod frame 51, a force is applied to the force-bearing rod frame 73 on the outer wall of the supporting area 71. The force-bearing rod frame 73 receives the force to drive the supporting area 71 to perform a limiting rotation on the limiting shaft body 62, and then the supporting area 71 can drive the acting area 72 and a plurality of flexible rubber pads 74 thereon to adjust the angle. That is, in the initial state, the pressing plate 7 (including the supporting area 71 and the acting area 72) located inside the plastic frame 4 will move to the outside of the plastic frame 4 through the slot 41;

[0035] A torsion spring one 63 is connected between the installation sleeve 61 and the limiting shaft body 62, and a return spring 64 is fixedly installed on the inner wall of the bottom of the plastic frame 4. The return spring 64 is in contact with the supporting area 71. A rolling sphere 76 is installed on the supporting area 71 and is movably connected to its inner wall. The connection between the rolling sphere 76 and the supporting area 71 is preferably connected in a rolling limit manner. An arc-shaped convex block 52 is fixedly installed on the inner wall of the moving frame 5. When the acting area 72 rotates to the outside of the plastic frame 4 through the slot 41, the rolling sphere 76 is located on the movement track of the arc-shaped convex block 52.

[0036] To facilitate the operator to rotate the double-layer winding sleeve 81, the present invention installs a moving shaft body 83 slidably connected to its inner wall on the double-layer winding sleeve 81. One end of the moving shaft body 83 penetrates through the inner wall of the top of the circular sleeve 8 and extends to the outside. A cavity 84 is provided at the bottom of the circular sleeve 8, and the other end of the moving shaft body 83 is located inside the cavity 84. A torsion spring two 89 is connected between the inner walls of the double-layer winding sleeve 81 and the circular sleeve 8. A telescopic shaft body 85 is fixedly installed in the area where the moving shaft body 83 is located inside the cavity 84. During the specific installation process, the operator can rotate the two moving shaft bodies 83 in sequence, so that the double-layer winding sleeve 81 rotates. A plurality of guiding block bodies 86 are fixedly installed on the inner wall of the cavity 84, and the guiding block bodies 86 are evenly distributed at equal angles in a ring shape on the inner wall of the cavity 84. One side of the guiding block body 86 is an inclined surface and the other side is a right-angle surface. The guiding block body 86 is located on the movement track of the telescopic shaft body 85. Combined with the attached Figure 12 As shown, when the moving shaft body 83 rotates clockwise (i.e., the double-layer winding sleeve 81 rotates forward), the telescopic shaft body 85 on the outer wall of the moving shaft body 83 will first pass through the inclined surface of the guiding block body 86 during the movement. If the moving shaft body 83 rotates in the reverse direction, it will be blocked by the right-angle surface of the guiding block body 86. A circular track 87 fixedly connected to the inner wall of the cavity 84 is provided below the guiding block body 86, and a plurality of vertical slide rails 88 corresponding to the telescopic shaft body 85 are fixedly installed on the circular track 87. The telescopic shaft body 85 can be limited and slide in the vertical slide rails 88 and the circular track 87. A buffer spring 80 is fixedly installed on the inner wall of the bottom of the cavity 84, and the end of the moving shaft body 83 is in contact with the buffer spring 80.

[0037] Specifically, when installing the mainboard body 3, the operator first places the mainboard body 3 inside the lower cover 2, and then aligns the reserved installation holes of the mainboard body 3 with the screw holes of the lower cover 2. After alignment, the staff presses the lower cover 2 with one hand and rotates one end of one of the movable shafts 83 located outside the circular sleeve 8 with the other hand. It should be noted that when assembling the mobile phone, it is usually placed on a plane, so that the lower cover 2 is not easily displaced when subjected to force. The movable shaft 83 drives the double-layer winding sleeve 81 to rotate clockwise, so that the movable frame 5 moves in the plastic frame 4 under the action of the rope body 82. During the movement of the movable frame 5, the action rod frame 51 on the inner wall thereof applies a force to the force-bearing rod frame 73 on the outer wall of the supporting area 71, so that the supporting area 71 rotates on the limiting shaft 62. Since the supporting area 71 is slidably connected to the limiting shaft 62, the limiting shaft 62 rotates synchronously with it, and the limiting During the rotation of the shaft body 62, the torsion spring 63 between it and the mounting sleeve 61 will be deformed, and then the support area 71 drives the action area 72 to move from the inside of the plastic frame 4 to the outside through the slot 41. At this time, the action area 72 and the flexible rubber pad 74 thereon will move to the top of the main board body 3, but will not contact the main board body 3. When the multiple action rod frames 51 on the inner wall of the moving frame 5 no longer apply force to the force-bearing rod frames 73, the pressing plate 7 (including the support area 71 and the action area 72) has been adjusted in angle, and the operator can observe the alignment of the reserved mounting holes of the lower main board body 3 and the screw holes of the lower cover 2. If they are still in the aligned state, the moving shaft body 83 can continue to rotate clockwise;

[0038] As mentioned above, when the movable shaft body 83 rotates clockwise, the telescopic shaft body 85 on the outer wall of the movable shaft body 83 will move synchronously with it. Figure 10 and attached Figure 11 As shown in the figure, during the movement, the end of the telescopic shaft 85 will pass through the guide block 86 and move along the inclined surface of the guide block 86. When the telescopic shaft 85 passes through the inclined surface of the guide block 86, the telescopic shaft 85 will be affected by the dumping surface of the guide block 86 and shrink, and move to the right angle surface of the guide block 86 to reset. When the double-layer winding sleeve 81 rotates clockwise, the torsion spring 2 89 on the inner wall of the circular sleeve 8 will deform accordingly. Then, when the operator observes the alignment of the reserved mounting hole of the main board body 3 and the screw hole of the lower cover 2: the torsion spring 2 89 will drive the double-layer winding sleeve 81 to rotate counterclockwise. However, since the moving shaft 83 and the inner wall of the double-layer winding sleeve 81 are in sliding connection, and the telescopic shaft 85 on the outer wall of the moving shaft 83 will be hindered by the right angle surface of the guide block 86 during the counterclockwise rotation, the moving shaft 83 and the double-layer winding sleeve 81 cannot rotate counterclockwise in the above state.

[0039] During observation, if the reserved mounting holes of the main board body 3 are aligned with the screw holes of the lower cover 2, the staff can continue to rotate the moving shaft body 83, and the double-layer winding sleeve 81 will continue to drive the moving frame 5 to move through the rope body 82. As shown in the attached Figure 7 figure, the arc-shaped convex block 52 on the inner wall of the moving frame 5 will move synchronously with it. Since the pressing plate 7 (including the support area 71 and the acting area 72) has been adjusted in angle, the rolling sphere 76 will then be adjusted to the movement track of the arc-shaped convex block 52. When the arc-shaped soil block moves to the rolling sphere 76, it will apply a force to the rolling sphere 76, causing the pressing plate 7 to move downward, and during the downward movement, the return spring 64 will be compressed. The acting area 72 on the pressing plate 7 will cause the flexible rubber pad 74 to contact the main board body 3 during the downward movement. It should be noted that the flexible rubber pad 74 is in an arc-shaped outward expansion state. Therefore, during the downward movement, the flexible rubber pad 74 will change its shape and expand outward on the main board body 3 to increase the limiting area, so as to achieve the purpose of pre-fixing the main board body 3. At this time, the main board body 3 has been preliminarily limited. Subsequently, the operator continues to rotate another moving shaft body 83 and repeats the above operation. After the pre-fixing of the main board body 3 is completed, the corresponding screw installation operation can be carried out;

[0040] Combined with the attached Figures 9-12As shown, it should be noted that during the process of the moving shaft body 83 rotating from the start to the end (the end of rotation means that the flexible rubber pad 74 pre-fixes the main board body 3), the telescopic shaft body 85 on the outer wall of the moving shaft body 83 rotates from directly above one vertical slide rail 88 to directly above the other vertical slide rail 88. If the subsequent staff needs to disassemble the main board body 3, the moving shaft body 83 can be pressed down so that the telescopic shaft body 85 enters the vertical slide rail 88 (at this time, the telescopic shaft body 85 does not pass through the guiding block 86 during the movement process). During the pressing process, the buffer spring 80 is in a compressed state. When the telescopic shaft body 85 passes through the corresponding vertical slide rail 88 and enters the annular track 87, the double-layer winding sleeve 81 will rotate counterclockwise under the action of the torsion spring two 89. When the telescopic shaft body 85 rotates to directly below the corresponding vertical slide rail 88 in the initial state, the moving shaft body 83 will, under the action of the compressed buffer spring 80, cause the telescopic shaft body 85 to return to the initial position through the vertical slide rail 88. During the counterclockwise rotation of the moving shaft body 83, the constant force spring 53 will cause the moving frame 5 to move towards the initial position, so that the arc-shaped convex block 52 no longer exerts a force on the rolling sphere 76. The pressing plate 7 rises to the initial height under the action of the reset spring 64. Subsequently, the acting rod frame 51 on the inner wall of the moving frame 5 will exert a force on the stressed rod frame 73 during the reset process. Then, the pressing plate 7 will return to the plastic frame 4 again under the action of the torsion spring one 63. The operator can disassemble the main board body 3. Through the structural design of the present invention, on the one hand, it is convenient for the operator to install the main board body 3, and on the other hand, the fixed strength of the main board body 3 can be effectively increased through the flexible rubber pad 74, avoiding the loosening of the main board body 3 during the use by the user.
