Description

Technical Field

[0001] This utility model relates to the field of mobile phone reinforcing steel sheet technology, and more specifically, to a mobile phone reinforcing steel sheet with an installation and positioning structure. Background Technology

[0002] Mobile phone reinforcing steel sheets are typically thin sheets made of stainless steel or other metal materials, with a thickness generally between 0.1-0.3mm. They are precisely fitted into key parts inside the phone, such as between the circuit board, display screen, and casing. When the phone is subjected to external forces (such as squeezing, bending, or dropping), stress concentration occurs in the phone's structure. The reinforcing steel sheet can disperse these concentrated stresses over a larger area, thereby reducing the peak value of local stress. However, existing mobile phone reinforcing steel sheets lack a positioning structure, leading to installation deviations due to inaccurate alignment during installation, which affects the effectiveness of the reinforcing steel sheet.

[0003] To address the aforementioned issues, regarding the technical problem that existing mobile phone reinforcing steel sheets lack a positioning structure, resulting in inaccurate alignment during installation and thus affecting the effectiveness of the reinforcing steel sheets, after extensive searching, a mobile phone reinforcing steel sheet with an installation positioning structure was found with patent publication number CN216391514U. This belongs to the technical field of mobile phone reinforcing steel sheets. This device uses a first positioning adhesive to fix the mobile phone reinforcing steel sheet to a flexible circuit board, and then presses downward to connect the internal pressing post with the surface of the flexible circuit board, thereby using the positioning structure to position the reinforcing steel sheet. Finally, it is fixed through the second fixing port on the limiting plate.

[0004] However, the aforementioned mobile phone reinforcing steel sheet with an installation and positioning structure still has some problems. For example, when the device fixes the mobile phone reinforcing steel sheet to the flexible circuit board through the positioning structure, the reinforcing steel sheet cannot achieve large-area positioning of the edge of the flexible circuit board, causing the two to easily loosen during later use, thus leading to easy damage later. To address the above problems, this utility model proposes a mobile phone reinforcing steel sheet with an installation and positioning structure. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a mobile phone reinforcing steel sheet with an installation and positioning structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone reinforcing steel sheet with an installation and positioning structure, comprising: a reinforcing steel sheet body, two positioning plates slidably connected to its two sides, multiple sliders fixedly connected to the bottom of the positioning plates, a sliding groove for the sliders to slide on the bottom of the reinforcing steel sheet body, a fixing box fixedly connected to the bottom of the reinforcing steel sheet body, and an adjustment mechanism for driving the two positioning plates to move relative to each other within the fixing box, the adjustment mechanism comprising:

[0007] A drive disk is rotatably mounted inside the fixed box via a rotating shaft. A torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are fixedly connected to the drive disk and the fixed box, respectively. Two drive rods are rotatably connected to the drive disk.

[0008] Two movable rods, the first end of which is fixedly connected to the two positioning plates respectively, and the second end of which is hinged to the two driving rods respectively, and the two movable rods pass through and are movably mounted on the fixed box.

[0010] A further preferred embodiment: both sides of the two positioning plates are fixedly connected to side plates, and the side plates are fixedly connected to the top plate.

[0011] A further preferred embodiment: the bottom of the top plate has an arc-shaped guide surface that slopes toward the top plate.

[0012] A further preferred embodiment: buffer pads are fixedly connected to the arc-shaped guide surface of the top plate and the side of the positioning plate facing the reinforcing steel sheet body.

[0013] A further preferred embodiment: a second adhesive tape is fixedly connected to the buffer pad on the positioning plate.

[0014] A further preferred embodiment: the positioning plate is provided with a plurality of first through holes.

[0015] A further preferred embodiment: the reinforcing steel sheet body is provided with multiple second through holes, and multiple first adhesive tapes are fixedly connected at intervals on the reinforcing steel sheet body.

[0016] Beneficial effects:

[0017] 1. By setting up an adjustment mechanism and positioning plates, the adjustment mechanism drives the two positioning plates to move relative to each other, so that the positioning plates can position the edge of the flexible circuit board over a large area, avoiding the phenomenon that the two may loosen during later use.

[0018] 2. By setting side plates and top plates, the protection and stability of the circuit board are improved through the combined action of the side plates and top plates. At the same time, it can also provide a certain degree of protection for other components that may be above it, preventing other components from being damaged by direct hard contact with the edge of the positioning plate or reinforcing steel sheet due to accidental squeezing or collision, thus playing a buffering and isolation role.

[0019] 3. By setting up a first through hole, a second through hole, a first adhesive tape, and a second adhesive tape, the stability of the circuit board installation is improved through the setting of multiple sets of adhesive tapes, and the setting of multiple through holes helps the heat dissipation and ventilation inside the phone, ensuring that the heat can be dissipated in time during long-term use or high-load operation, and avoiding the impact on performance or even damage caused by the overheating of internal components due to heat accumulation.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0026] Please see Figure 1-4In this embodiment of the utility model, a mobile phone reinforcing steel sheet with an installation and positioning structure includes a reinforcing steel sheet body 1, two positioning plates 2 are slidably connected to each other on both sides, multiple sliders 8 are fixedly connected to the bottom of the positioning plates 2, a sliding groove 10 for the sliders 8 to slide is fixedly connected to the bottom of the reinforcing steel sheet body 1, and a fixed box 11 is fixedly connected to the bottom of the reinforcing steel sheet body 1. The fixed box 11 is provided with an adjustment mechanism 9 for driving the two positioning plates 2 to move relative to each other. The adjustment mechanism 9 includes a drive disk 95, which is rotatably set in the fixed box 11 through a rotating shaft 93. A torsion spring 94 is sleeved on the rotating shaft 93. The two ends of the torsion spring 94 are fixedly connected to the drive disk 95 and the fixed box 11 respectively. Two drive rods 92 and two movable rods 91 are rotatably connected to the drive disk 95. The first ends of the two movable rods 91 are fixedly connected to the two positioning plates 2 respectively, and the second ends of the two movable rods 91 are hinged to the two drive rods 92 respectively. The two movable rods 91 are traversed and movably set on the fixed box 11.

[0027] Specifically, initially, under the action of the torsion spring 94, the drive plate 95 is in a relatively stable initial position. At this time, the two positioning plates 2 connected to the drive plate 95 through the drive rod 92 and the movable rod 91 are also in their default relative positions. The slider 8 is located at a specific position in the bottom groove 10 of the reinforcing steel sheet body 1. The entire structure is in a balanced state, waiting for adjustment during installation. When it is necessary to adjust the position of the positioning plate 2 to adapt to different installation environments inside the mobile phone or to better cooperate with other components, by pulling one of the positioning plates 2, the movable rod 91 moves and drives the drive rod 92 to move. The drive rod 92 drives the drive plate 95 to rotate, and the rotation of the drive plate 95 applies a force to the torsion spring 94, thereby causing the other drive rod 92 on the drive plate 95 to drive the other movable rod 91 to move, thus realizing the relative movement of the other positioning plate 2. After installation, the reinforcing steel sheet body 1 and the positioning plate 2 can be fixed by external equipment. Then, the mobile phone circuit board is installed on the reinforcing steel sheet body 1. After installation, the positioning plate 2 is released, so that the positioning plate 2 drives the two drive rods 92 to reset under the force of the torsion spring 94. In turn, the movable rod 91 drives the two positioning plates 2 to reset, thereby realizing the positioning of the circuit board. The overall structure has high linkage. The relative position of the two positioning plates 2 can be precisely controlled by the adjustment mechanism 9. Thus, when installing the circuit board, the position of the positioning plate 2 can be flexibly adjusted according to the specific installation position inside the mobile phone and the requirements of other components that cooperate with it, so as to achieve more accurate installation positioning, improve the accuracy and adaptability of installation. At the same time, the positioning plate 2 can achieve large-area positioning of the edge of the flexible circuit board, avoiding the phenomenon that the two are prone to loosening in later use.

[0028] It should be noted that when designing the installation and positioning structure of the mobile phone reinforcing steel sheet, compatibility with other components of the mobile phone must be fully considered. For example, the position adjustment range of the positioning plate 2 must adapt to the layout and installation space requirements of different components inside the mobile phone and must not interfere with other components. At the same time, after installation, the reinforcing steel sheet must cooperate well with important components such as the motherboard and display screen of the mobile phone to enhance the structural strength without affecting the normal function and performance of the mobile phone. Secondly, the circuit board can be fixed to the reinforcing steel sheet body 1 by pinching and sticking. The installation method of the reinforcing steel sheet body 1 and the mobile phone is existing technology. The fixing box 11 is provided with a strain groove 13 through which the movable rod 91 can move. The length of the strain groove 13 is the same as the width of the movable rod 91 to accommodate the movement of the movable rod 91 and the drive rod 92, ensuring the normal operation of the device.

[0029] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the top of each of the two positioning plates 2 is fixedly connected to a top plate 3 relative to the reinforcing steel sheet body 1, and the two positioning plates 2 are fixedly connected to side plates 4 on both sides. The side plates 4 are fixedly connected to the top plate 3. Specifically, inside the mobile phone, after the circuit board is installed, the top plate 3 and the side plates 4 can play a certain protective role for other components that may be above them, preventing other components from being damaged by direct hard contact with the edge of the positioning plate 2 or the reinforcing steel sheet body 1 due to accidental squeezing, collision, etc., thus playing a buffering and isolation role, and further improving the stability of the circuit board fixing.

[0030] In this embodiment of the utility model, such as Figure 4 As shown, the bottom of the top plate 3 has an arc-shaped guide surface that is inclined toward the top plate 3. Specifically, the arc-shaped guide surface can play a guiding role to facilitate the installation of the circuit board.

[0031] In this embodiment of the utility model, such as Figure 4 As shown, buffer pads 14 are fixedly connected to the arc-shaped guide surface of the top plate 3 and the side of the positioning plate 2 facing the reinforcing steel sheet body 1. Specifically, when an external force is applied to the top plate 3 or the positioning plate 2, the buffer pad 14 will bear the external force first. Its material properties will cause it to undergo elastic deformation to absorb and disperse the external force, thereby improving the protection of the circuit board. Furthermore, a second adhesive tape 15 is fixedly connected to the buffer pad 14 on the positioning plate 2. The second adhesive tape 15 facilitates the adhesion and fixation of the circuit board. Secondly, multiple first through holes 5 are provided through the positioning plate 2. The first through holes 5 help to dissipate heat and ventilate the inside of the mobile phone, ensuring that the heat can be dissipated in time when the mobile phone is used for a long time or under high load, avoiding the impact on performance or even damage caused by the excessive temperature of the internal components of the mobile phone due to heat accumulation.

[0032] In this embodiment of the utility model, such as Figure 1 and Figure 2 As shown, the reinforcing steel sheet body 1 has multiple second through holes 6, and multiple first adhesive strips 7 are fixedly connected at intervals on the reinforcing steel sheet body 1. Specifically, when installing the mobile phone reinforcing steel sheet, the second through holes 6 can also play the role of ventilation and heat dissipation, promoting the dissipation of heat inside the mobile phone, while the first adhesive strips 7 facilitate the installation of the circuit board and the reinforcing steel sheet body 1.

[0033] Working principle: When the circuit board needs to be installed, pulling one of the positioning plates 2 causes the movable rod 91 to move, which in turn moves the drive rod 92. The drive rod 92 drives the drive disk 95 to rotate, and the rotation of the drive disk 95 applies a force to the torsion spring 94, thereby causing another drive rod 92 on the drive disk 95 to drive another movable rod 91 to move, thus realizing the relative movement of the other positioning plate 2. Then, the reinforcing steel sheet body 1 and the positioning plate 2 can be fixed by external equipment. Then, the mobile phone circuit board is installed on the reinforcing steel sheet body 1 and fixed by the first adhesive tape 7. After installation, by releasing the positioning plate 2, the positioning plate 2 moves under the force of the torsion spring 94, causing the two... The root drive rod 92 resets, thereby driving the two positioning plates 2 to reset via the movable rod 91, achieving the positioning of the circuit board. At this time, the low-mounted enclosure, side plate 4, and top plate 3 form a semi-enclosed shape to fix the circuit board. The overall structure has high linkage. The relative position of the two positioning plates 2 can be precisely controlled by the adjustment mechanism 9. Thus, when installing the mobile phone reinforcing steel sheet, the position of the positioning plate 2 can be flexibly adjusted according to the specific installation location inside the mobile phone and the requirements of other components that cooperate with it, achieving more precise installation positioning, improving the accuracy and adaptability of installation. At the same time, the positioning can achieve large-area positioning of the edge of the flexible circuit board, avoiding the phenomenon of loosening between the two in later use.
