Description

Technical Field

[0001] This utility model relates to the field of electronic circuits, and in particular to a novel integrated I / O board structure. Background Technology

[0002] In the field of electronic equipment, integrated I / O boards, as key components for signal transmission, data sampling, and device control, are widely used in industrial automation control, intelligent device data interaction, and other scenarios. Their performance and assembly stability directly affect the operational reliability and lifespan of electronic equipment.

[0003] Currently, traditional integrated I / O boards mostly use a single slot-insertion method when assembling circuit boards, inserting the circuit board into corresponding slots on the front and rear boards for fixation. This assembly method has obvious drawbacks: on the one hand, relying solely on slot insertion lacks an effective guiding and positioning structure, causing the circuit board to easily shift during insertion, making it difficult to quickly and accurately align and greatly affecting assembly efficiency; on the other hand, fixing only with slots cannot eliminate assembly gaps, and during equipment operation, external vibrations can easily cause the circuit board to loosen, thereby affecting signal transmission stability and even causing circuit board damage.

[0004] Therefore, a novel integrated I / O board structure is proposed to address the aforementioned issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel integrated I / O board structure, which aims to improve the problems of difficult alignment, low efficiency, and easy loosening and damage in the traditional single slot insertion method of integrated I / O boards in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel integrated I / O board structure includes a front board, a rear board, a circuit board, sockets, a mounting mechanism, and a stabilizing mechanism;

[0008] The installation mechanism includes a positive and negative threaded rod, an anti-detachment block, a driven wheel, a driving wheel, and a rotating shaft. The positive and negative threaded rod passes through the front plate and the rear plate. The driving wheel is rotatably connected to the front plate through the rotating shaft. The driving wheel meshes with the driven wheel. The driven wheel is sleeved on the positive and negative threaded rod. The anti-detachment block is located on the outside of the front plate and the rear plate.

[0009] The stabilizing mechanism includes a connecting sleeve, a clamping cam, a slot, and an elastic pressure plate. The inner side of the connecting sleeve is slidably connected to the outer side of the rotating shaft, and the connecting sleeve is rotatably connected to the outer side of the front plate and the rear plate. The two ends of the clamping cam are rotatably connected to the inner side of the connecting sleeve. The slot is opened on one side of the front plate and the rear plate, and the elastic pressure plate is located in the slot.

[0010] As a further description of the above technical solution:

[0011] The circuit board is located between the front board and the rear board. The circuit board includes a sub-board, integrated components, and insert strips. The circuit board is inserted and mated with the corresponding slots of the front board and the rear board through the insert strips.

[0012] As a further description of the above technical solution:

[0013] The driving wheel and the driven wheel are arc-toothed cylindrical gears, and their modules and pressure angles are matched.

[0014] As a further description of the above technical solution:

[0015] The elastic pressure plate is made of metal elastic material, has a U-shaped structure, and is fixed at both ends to the inner wall of the slot, while the middle part contacts the outer side of the insert.

[0016] As a further description of the above technical solution:

[0017] The end of the rotating shaft is provided with an adapter groove, and the convex end of the clamping cam is adapted to the shape of the adapter groove.

[0018] As a further description of the above technical solution:

[0019] Both the front plate and the rear plate have movable cavities inside, where the driving wheel and the driven wheel rotate. The inner sidewall of the movable cavity is provided with rough texture to provide friction for the driving wheel.

[0020] As a further description of the above technical solution:

[0021] The main body of the circuit board has a multi-type communication and control module area, a USB communication and control sub-module area, a current and voltage sampling module area, and a sensor and relay control module area on one side.

[0022] As a further description of the above technical solution:

[0023] The socket is located on the front panel, and an anti-static rubber pad is provided at the socket interface slot.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, the circuit board is quickly assembled by inserting the insert strip into the slots of the front and rear plates, and by fixing the two ends of the U-shaped metal elastic pressure plate and contacting the insert strip in the middle. The insert strip guides and positions the circuit board, and the elastic pressure plate holds it in place. At the same time, the elastic pre-tightening force is used to offset the assembly gap and buffer external vibration, so that the initial installation of the circuit board is both convenient and has basic stability, creating favorable conditions for subsequent precise installation.

[0026] 2. In this utility model, the connecting sleeve drives the rotating shaft, which in turn drives the active wheel and the driven wheel to mesh and transmit power. In conjunction with the positive and negative threaded rods that pass through the front and rear plates, the precision of the gear transmission and the bidirectional adjustment characteristics of the positive and negative threaded rods drive the relative movement of the front and rear plates, achieving precise micro-adjustment of the circuit board installation position. Furthermore, the anti-detachment block limits the axial displacement of the threaded rod, and the clamping cam increases the friction of the active wheel to prevent rotation. The multiple structures work together to ensure a stable and controllable installation process, greatly improving the installation accuracy and structural reliability of the circuit board.

Detailed Implementation

[0034] 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.

[0035] Reference Figures 1 to 5This utility model provides an embodiment of a novel integrated I / O board structure, comprising a front panel 1, a rear panel 2, a circuit board 3, a socket 4, a mounting mechanism 5, and a stabilizing mechanism 6. The front panel 1 and rear panel 2 serve as the basic load-bearing components of the entire structure, providing mounting frame support for other components, defining the mounting space and relative positions of each component, and ensuring the stability of the overall form and layout. The circuit board 3, as the core component realizing the functions of the integrated I / O board, has a multi-type communication and control module area, a USB communication and control sub-module area, a current and voltage sampling module area, and a sensor and relay control module area on one side of its main body. It can be used to process and transmit various types of communication and control signals, adapt to USB-related communication and control requirements, collect and monitor current and voltage parameters, connect sensors and control relays, and realize various tasks such as signal transmission, data sampling, and device control with external devices. The socket 4 is located on the front panel 1 and serves as an interface component for connecting and communicating with external devices, used to realize input and output interaction of signals, power, etc. The anti-static rubber pads set at the interface slots can effectively absorb and release static electricity, avoiding interference from static electricity to signal transmission and preventing static electricity from damaging internal sensitive electronic components.

[0036] The mounting mechanism 5 includes a positive and negative threaded screw 501, an anti-detachment block 502, a driven wheel 503, a driving wheel 504, and a rotating shaft 505. The positive and negative threaded screw 501 passes through the front plate 1 and the rear plate 2. Relying on its unique positive and negative thread structure, it can convert rotation into relative linear motion between the front plate 1 and the rear plate 2 along the screw axis during rotation, causing the front plate 1 and the rear plate 2 to move closer or further apart, thereby adjusting the mounting position of the circuit board 3 in the direction of the distance between the front and rear plates 2. The driving wheel 504 is rotatably connected to the front plate 1 through the rotating shaft 505 and meshes with the driven wheel 503. As the driving component of the gear transmission, it rotates under the action of external force. Relying on the module and pressure angle adapted to the driven wheel 503, it stably transmits the rotational power to the driven wheel 503. The driven wheel 503 is sleeved on the positive and negative threaded screw 501, receives the power transmitted by the driving wheel 504, and converts the rotation of the driving wheel 504 into its own rotation. The drive wheel 504 and driven wheel 503 are arc-shaped cylindrical gears with matched modules and pressure angles to ensure the stability and accuracy of the transmission. The anti-detachment block 502 is located on the outside of the front plate 1 and the rear plate 2 to axially limit the drive wheel 501, preventing the wheel from axially moving or detaching from the front plate 1 and the rear plate 2, thus ensuring the continuous and stable realization of the transmission and position adjustment functions of the installation mechanism 5. The front plate 1 and the rear plate 2 are both provided with movable cavities to provide rotation space for the drive wheel 504 and driven wheel 503, allowing the gear transmission components to be built into them, ensuring a compact layout of the installation mechanism 5. The inner sidewall of the movable cavity is provided with rough texture to provide friction force to the drive wheel 504. When a stable installation process is required, this friction force can be used to limit the free rotation of the drive wheel 504, enhancing the transmission stability of the installation mechanism 5.

[0037] The stabilizing mechanism 6 includes a connecting sleeve 601, a clamping cam 602, a slot 603, and an elastic pressure plate 604. The inner side of the connecting sleeve 601 is slidably connected to the outer side of the rotating shaft 505 and rotatably connected to the outer sides of the front plate 1 and the rear plate 2. As a force-bearing component for external forces acting on the mounting mechanism 5, it receives external rotational forces and transmits them to the rotating shaft 505, while providing a basic structure for the rotational connection of the clamping cam 602. The two ends of the clamping cam 602 are rotatably connected to the inner side of the connecting sleeve 601. Its convex end is adapted to the shape of the matching groove at the end of the rotating shaft 505. By rotating the clamping cam 602, the convex end can be engaged into the matching groove, applying force to the rotating shaft 505, causing the rotating shaft 505 to have a specific directional movement tendency, thereby pressing the driving wheel 504 against the inner wall of the movable cavity, increasing the rotational friction of the driving wheel 504, and restricting its rotation. The drive wheel 504 and the rotating shaft 505 rotate freely, enhancing the stability of the transmission process of the mounting mechanism 5. The slot 603 is located on the side of the front plate 1 and the rear plate 2, serving as the insertion and installation part of the circuit board 3 insert strip 303, providing insertion space for the insert strip 303, and realizing the physical connection and positioning of the circuit board 3 with the front plate 1 and the rear plate 2 during initial assembly. The elastic pressure plate 604 is made of metal elastic material and has a U-shaped structure. Both ends are fixed to the inner wall of the slot 603, and the middle part contacts the outer side of the insert strip 303. When the circuit board 3 is inserted into the slot 603 through the insert strip 303, the elastic force generated by its own elastic deformation forms an elastic clamp on the insert strip 303, realizing the elastic pre-fixation of the circuit board 3 after initial assembly, assisting the insertion and cooperation of the insert strip 303 and the slot 603, offsetting the assembly gap, and buffering external vibration.

[0038] Circuit board 3 is located between front board 1 and rear board 2. Circuit board 3 includes sub-board 301, integrated components 302, and insert strips 303. Sub-board 301, as a component of circuit board 3, can undertake specific sub-functions and assist the functional modules on the main circuit board 3 to achieve their corresponding functions more efficiently and accurately. Integrated components 302 are integrated on circuit board 3 and are the basic electronic components for realizing various functions of circuit board 3. Through the combination and collaborative work of different integrated components 302, circuit board 3 has multiple types of communication and control, sampling, and device control functions. Insert strips 303 are used to plug into slots 603 of front board 1 and rear board 2. They serve as a bridge for physical connection, signal and power transmission between circuit board 3 and front and rear boards 2, realize the installation and fixation of circuit board 3 between front and rear boards 2, and ensure the signal and power path between circuit board 3 and other parts of the IO board. Circuit board 3 is plugged into corresponding slots 603 of front board 1 and rear board 2 through insert strips 303.

[0039] Working principle: First, the circuit board is initially assembled by aligning the inserts on the circuit board with the slots on the front and rear boards. The circuit board is installed between the front and rear boards by using the insertion and engagement of the inserts with the corresponding slots. At this time, the U-shaped elastic pressure plate, made of metal elastic material, is fixed at both ends to the inner wall of the slot, and the middle part will contact the outer side of the insert, forming an initial elastic limit for the insert.

[0040] Next, the installation mechanism's workflow is initiated. External force is applied to the connecting sleeve, causing it to rotate, which in turn drives the shaft to rotate, causing the driving wheel to rotate. Since the driving and driven wheels are meshed arc-toothed cylindrical gears with matched modules and pressure angles, the rotation of the driving wheel drives the driven wheel to rotate. The driven wheel is fitted onto a threaded rod that runs through the front and rear plates; the rotation of the driven wheel causes the threaded rod to rotate. As the threaded rod rotates, its own threaded structure causes the front and rear plates to move closer or further apart, allowing for further adjustment of the circuit board's mounting position. Simultaneously, anti-detachment blocks located on the outer sides of the front and rear plates prevent the threaded rod from axially disengaging.

[0041] When stabilization of the installation process is required, the convex end of the clamping cam is rotated and engaged with the adapter groove. Utilizing the structural characteristics of the clamping cam, the rotating shaft tends to move in the same direction as the pressure, thereby pressing the drive wheel against the inner wall of the movable cavity. This increases friction, making it difficult for the drive wheel to rotate, thus enhancing the stability of the installation mechanism's transmission process and preventing the rotating shaft from rotating arbitrarily, which could affect the installation accuracy.

[0042] In addition, the anti-static rubber pads at the interface slots of the sockets on the front panel play a role in preventing static electricity when the entire device communicates with external devices through the sockets, ensuring stable signal transmission. The main board features multiple communication and control module areas, USB communication and control sub-module areas, current and voltage sampling module areas, and sensor and relay control module areas. After assembly, these modules can work with external devices to perform various signal transmission, data sampling, and device control functions, fulfilling the tasks of the integrated I / O board. The entire process, from circuit board assembly to the coordinated operation of the mounting and stabilizing mechanisms to ensure installation accuracy and stability, and finally to the functional modules of the sockets and circuit board, constitutes a complete working process for the new integrated I / O board structure.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
