Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile terminal circuit board technology, and in particular to a mobile terminal circuit board with a quick-release structure. Background Technology
[0002] During the equipment's lifespan, the demand for circuit board maintenance and upgrades due to technological iterations and fault repairs is increasing. These factors drive continuous innovation in materials, design, and manufacturing processes for mobile terminal circuit boards to adapt to industry development and technological changes.
[0003] However, in the existing technology, during the assembly and maintenance of mobile terminal circuit boards, the existing technology relies on small screwdrivers for installation and disassembly. Due to the extremely small internal space of mobile devices, the operating space of screwdrivers is limited, and operators need to spend a lot of energy to operate them. If they are not careful, problems such as slipping or misoperation will occur, which greatly increases the difficulty of the operation. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mobile terminal circuit board with a quick-release structure.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a mobile terminal circuit board with a quick-release structure, comprising:
[0006] roof;
[0007] A simplified assembly / disassembly component is placed inside a top plate. The simplified assembly / disassembly component includes an installation compartment fixedly connected to the bottom of the top plate. An inner sliding frame is slidably connected to the installation compartment. An extension rod is fixedly connected to the inner sliding frame. A vertical sliding plate is slidably connected to the extension rod. An upper sliding frame is fixedly connected to the vertical sliding plate. A limit rod is fixedly connected to the upper sliding frame. A bottom sliding frame is fixedly connected to the inner sliding frame. A lifting plate is slidably connected to the bottom sliding frame. A fixing plate is fixedly connected to the lifting plate. A conical plate is slidably connected to the fixing plate. A clamping frame is slidably connected to the conical plate. A lifting frame is slidably connected to the clamping frame. A vertical sliding frame is slidably connected to the lifting frame. An internal rod is fixedly connected to the vertical sliding frame. The internal rod is fixedly connected to the limit rod via the extension frame. A return spring is connected to the upper sliding frame.
[0008] In a preferred embodiment, a limiting shaft is fixedly connected to the reset spring, a vertical rod is fixedly connected to the limiting shaft, a sliding hole is provided on the limiting rod, and the limiting shaft is slidably connected to the sliding hole on the limiting rod.
[0009] Using the above technical solution: In use, by setting a limiting shaft, the limiting shaft can be inserted into the limiting rod to limit the limiting rod.
[0010] In a preferred embodiment, the installation compartment is provided with a sliding groove, and the built-in rod is slidably connected in the sliding groove.
[0011] The above technical solution is adopted: during use, a sliding groove is provided on the installation chamber to facilitate the sliding of the built-in rod, thus avoiding the built-in rod being blocked and unable to move up and down.
[0012] In a preferred embodiment, the vertical sliding frame is slidably connected to the top plate, a first rotating shaft is rotatably connected to the vertical sliding frame, the first rotating shaft is rotatably connected to the lifting frame, and a second rotating shaft is rotatably connected to the clamping frame, the second rotating shaft being rotatably connected to the top plate.
[0013] The above technical solution is adopted: by setting a second rotating shaft, the sliding between the top plate and the clamping frame is more flexible.
[0014] In a preferred embodiment, there are two first rotating shafts, which are rotatably connected to both ends of the lifting frame, and the clamping frame is rotatably connected to the first rotating shaft on the side away from the vertical sliding frame.
[0015] Using the above technical solution: when in use, the connection between the first rotating shaft and the sliding frame allows the lifting frame to move the clamping frame.
[0016] In a preferred embodiment, a fixing spring is fixedly connected to the fixing plate, and the side of the fixing spring away from the fixing plate is fixedly connected to the tapered plate.
[0017] The above technical solution is adopted: When in use, when the tapered plate slides into contact with the clamping frame, it will be squeezed inward to compress the fixing spring, so that the tapered plate can slide smoothly between the clamping frames on both sides.
[0018] In a preferred embodiment, a circuit board body is slidably connected to the lifting plate.
[0019] The above technical solution is adopted: when in use, the circuit board body slides on the bottom slide frame, so that when it is inserted into the installation chamber, it can drive the overall bottom slide frame to move. The bottom slide frame has openings that match the fixing plate, so that the fixing plate can slide in it.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] This invention eliminates the traditional screwdriver-based assembly and disassembly method. Simply insert the circuit board body into the bottom sliding frame, and through the linkage of components such as the extension rod, vertical sliding plate, and lifting frame, the clamping frame automatically lifts and resets, achieving rapid fixing and release of the circuit board. This significantly reduces operational difficulty. The rubber fixing plate provides flexible compressive force, avoiding the risk of damage to circuit board components due to improper screw tightening torque. Simultaneously, the locking design of the limiting shaft and limiting rod ensures the stability of the fixed state and prevents poor contact. It eliminates the repeated disassembly and assembly steps of multiple screws, simplifying circuit board installation and disassembly to two actions: insertion and extraction. This greatly shortens operation time, meeting the needs of rapid production and efficient maintenance of mobile terminal products. It also solves the problem in the prior art where the extremely limited internal space of mobile devices restricts screwdriver operation space, requiring operators to expend considerable effort.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] like Figure 1-5 As shown, this utility model provides a technical solution: a mobile terminal circuit board with a quick-release structure, comprising:
[0033] Top plate 1;
[0034] Simplified assembly / disassembly component 2 is placed inside the top plate 1. Component 2 includes an installation compartment 21 fixedly connected to the bottom of the top plate 1. An inner sliding frame 23 is slidably connected to the installation compartment 21. An extension rod 213 is fixedly connected to the inner sliding frame 23. A vertical sliding plate 214 is slidably connected to the extension rod 213. An upper sliding frame 215 is fixedly connected to the vertical sliding plate 214. A limit rod 216 is fixedly connected to the upper sliding frame 215. A bottom sliding frame 27 is fixedly connected to the inner sliding frame 23. A lifting plate 28 is slidably connected to the upper part of the 7. A fixing plate 29 is fixedly connected to the lifting plate 28. A conical plate 210 is slidably connected to the fixing plate 29. A clamping frame 26 is slidably connected to the conical plate 210. A lifting frame 25 is slidably connected to the clamping frame 26. A vertical sliding frame 24 is slidably connected to the lifting frame 25. An internal rod 218 is fixedly connected to the vertical sliding frame 24. The internal rod 218 is fixedly connected to the limiting rod 216 through an extension frame 217. A return spring 3 is connected to the upper sliding frame 215.
[0035] Furthermore, such as Figures 1 to 5 As shown, this utility model abandons the traditional screwdriver assembly and disassembly method. Simply insert the circuit board body 11 into the bottom sliding frame 27. Through the linkage of components such as the extension rod 213, vertical sliding plate 214, and lifting frame 25, the clamping frame 26 is automatically lifted and reset, achieving rapid fixing and release of the circuit board. This significantly reduces the difficulty of operation. The rubber fixing plate 29 provides flexible extrusion force, avoiding the risk of damage to circuit board components due to improper screw tightening torque. Simultaneously, the engaging design of the limiting shaft 32 and the limiting rod 216 ensures the stability of the fixed state and prevents poor contact. It eliminates the repeated assembly and disassembly steps of multiple screws, simplifying the installation and disassembly of the circuit board to two actions: insertion and extraction. This greatly shortens the operation time, meeting the needs of rapid production and efficient maintenance of mobile terminal products. It solves the problem in the prior art where the internal space of mobile devices is extremely small, limiting the operating space of screwdrivers and requiring operators to expend a great deal of effort.
[0036] like Figure 1 As shown, a limiting shaft 32 is fixedly connected to the reset spring 3, and a vertical rod 31 is fixedly connected to the limiting shaft 32. A sliding hole is provided on the limiting rod 216, and the limiting shaft 32 is slidably connected in the sliding hole on the limiting rod 216. In use, by setting the limiting shaft 32, the limiting shaft 32 can be inserted into the limiting rod 216 to limit the limiting rod 216.
[0037] like Figures 2 to 4 As shown, the mounting chamber 21 has a sliding groove 22, and the built-in rod 218 is slidably connected in the sliding groove 22. When in use, the sliding groove 22 on the mounting chamber 21 facilitates the sliding of the built-in rod 218, preventing the built-in rod 218 from being blocked and unable to move up and down.
[0038] like Figures 4 to 5 As shown, the vertical sliding frame 24 is slidably connected to the top plate 1. A first rotating shaft 212 is rotatably connected to the vertical sliding frame 24. The first rotating shaft 212 is rotatably connected to the lifting frame 25. A second rotating shaft 219 is rotatably connected to the clamping frame 26. The second rotating shaft 219 is rotatably connected to the top plate 1. By setting the second rotating shaft 219, the sliding between the top plate 1 and the clamping frame 26 becomes more flexible.
[0039] like Figure 2 As shown, there are two first rotating shafts 212, which are rotatably connected to the two ends of the lifting frame 25 respectively. The clamping frame 26 is rotatably connected to the first rotating shaft 212 on the side away from the vertical sliding frame 24. When in use, the connection between the first rotating shaft 212 and the sliding frame allows the lifting frame 25 to move the clamping frame 26.
[0040] like Figures 2 to 4 As shown, a fixing spring 211 is fixedly connected to the fixing plate 29. The side of the fixing spring 211 away from the fixing plate 29 is fixedly connected to the tapered plate 210. When in use, when the tapered plate 210 slides to contact the clamping frame 26, it will be squeezed inward to compress the fixing spring 211, so that the tapered plate 210 can slide smoothly between the clamping frames 26 on both sides.
[0041] The circuit board body 11 is slidably connected to the lifting plate 28. When in use, the circuit board body 11 slides on the bottom slide frame 27, so that when it is inserted into the installation chamber 21, it can drive the overall bottom slide frame 27 to move. The bottom slide frame 27 has an opening that matches the fixing plate 29, so that the fixing plate 29 can slide in it.
[0042] Working principle:
[0043] like Figure 1-5As shown, in use, the circuit board body 11 is directly inserted into the bottom slide frame 27, causing the bottom slide frame 27 to drive the inner slide frame 23 to move within the top plate 1, causing the inner slide frame 23 to drive the extension rod 213 to slide in the inclined groove on the vertical slide plate 214, causing the vertical slide plate 214 to be lifted, causing the vertical slide plate 214 to drive the upper slide frame 215 to be lifted, which in turn causes the upper slide frame 215 to drive the limit rod 216 to be lifted, causing the extension frame 217 to slide upward on the slide groove 22, causing the extension frame 217 to drive the built-in rod 218 to be lifted, causing the built-in rod 218 to drive the vertical slide frame 24 to be lifted, causing the vertical slide frame 24 to drive the lifting frame 25 to move, causing the lifting frame 25 to push the clamping frame 26 to rotate on the second rotating shaft 219, at which time the end of the clamping frame 26 away from the second rotating shaft 219 is driven to tilt up;
[0044] At the same time, the fixing plate 29 is moved to slide between the two clamping frames 26. When the clamping frames 26 are raised, the fixing plate 29 will be lifted, so that the rubber fixing plate 29 applies a squeezing force to the circuit board body 11 in the bottom sliding frame 27 to fix the circuit board body 11.
[0045] Prior to this, the operator moves the vertical rod 31 to make the limiting shaft 32 slide away from the extension frame 217, and the limiting rod 216 can slide. After the circuit board body 11 is inserted into the top plate 1, the operator releases the hand, so that the limiting shaft 32 is locked into the lower circular opening of the two circular openings on the limiting rod 216 under the action of the reset spring 3, thus completing the limiting of the limiting rod 216.
[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
