Description

Technical Field

[0001] This utility model relates to the field of PCB board technology, and in particular to an impact-resistant PCB board. Background Technology

[0002] A PCB (Printed Circuit Board) is an important electronic component, serving as the support for electronic components and the carrier for their electrical interconnections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board.

[0003] An existing type of vibration-damping PCB board (publication number: CN111356282B) uses screws and sleeves to facilitate the fixing of the PCB board and improve its vibration damping performance, preventing damage to the PCB board when dropped or collided. However, it can only buffer vertical vibrations. When faced with lateral or oblique impacts, the impact force cannot be effectively buffered and dissipated, which can easily cause the PCB board to twist and deform, leading to abnormal signal transmission, short circuits and other faults, affecting the stability and service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an impact-resistant PCB board.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An impact-resistant PCB board includes a mounting plate, a carrier plate, and a PCB body. The carrier plate is provided with a reinforcing support, and a movable seat is fixedly provided on the reinforcing support. A telescopic tube is movably mounted on the movable seat. A movable seat is provided at the end of the telescopic tube away from the movable seat. A guide sleeve is fixedly mounted on the carrier plate, and a screw is provided inside the guide sleeve.

[0007] As a further embodiment of this utility model, the second screw penetrates the guide sleeve, and the bottom end of the second screw is threadedly connected to the mounting plate.

[0008] As a further embodiment of this utility model, the movable seat 2 is fixedly connected to the bottom of the carrier plate, and the reinforcing supports are evenly distributed on the carrier plate.

[0009] As a further embodiment of this utility model, the end of the telescopic tube away from the first movable seat is movably connected to the second movable seat, and a spring is sleeved on the outside of the telescopic tube.

[0010] As a further embodiment of this utility model, a wear-resistant pad is fixedly provided at the bottom of the reinforcing support, and a rubber pad is fixedly provided at the bottom center of the carrier plate.

[0011] As a further embodiment of this utility model, the reinforcing brace is connected to the side wall of the carrier plate by screw one, and screw two are distributed at equal intervals on the carrier plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In use, by setting up reinforcing supports, wear-resistant pads, telescopic tubes, and springs, the telescopic tubes can swing flexibly with the cooperation of movable seat one and movable seat two. At the same time, by utilizing the elasticity of the springs, when the PCB body is subjected to lateral or oblique impacts, a reverse elastic force is generated, which can offset the impact force and drive the carrier board to return to its original position. It can also help absorb vertical vibrations, forming multi-directional buffers, thereby ensuring the stability of the PCB body. By placing a rubber pad at the bottom of the carrier board and passing screw two through the guide sleeve, the carrier board and the PCB body are fixed to the mounting plate, causing the carrier board to be pressed down evenly. After the rubber pad is compressed and deformed by the pressure of the carrier board, it can absorb the vertical impact force with its own elasticity, which can further enhance the vertical shock absorption effect, thereby improving the stability of the PCB body during installation and use.

[0022] Reference Figures 1-4 An impact-resistant PCB board includes a mounting plate 1, a carrier plate 2, and a PCB body 3. The carrier plate 2 is provided with a reinforcing support 101, and a movable seat 102 is fixedly provided on the reinforcing support 101. A telescopic tube 104 is movably installed on the movable seat 102. A movable seat 201 is provided at the end of the telescopic tube 104 away from the movable seat 102. A guide sleeve 203 is fixedly installed on the carrier plate 2, and a screw 202 is provided inside the guide sleeve 203.

[0023] In use, first attach the rubber pad 201 to the bottom of the carrier plate 2, and tighten the screw 202 that passes through the guide sleeve 203 with a tool to fix the carrier plate 2 and the PCB body 3 on the mounting plate 1. The rubber pad 201 absorbs vertical impact under pressure and deformation to ensure uniform force distribution. Then, use screw 106 to connect the "L"-shaped reinforcing support 101 to the side of the carrier plate 2, with the wear-resistant pad 103 at its bottom contacting the mounting plate 1. When subjected to lateral force, the wear-resistant pad 103 initially buffers the impact, and the telescopic tube 104 and spring 105 reset and offset the impact. When subjected to vertical force, the three work together to enhance the impact resistance.

[0024] In this embodiment, screw 202 penetrates and connects to guide sleeve 203, and the bottom end of screw 202 is threaded to mounting plate 1.

[0025] In use, the reinforcing brace 101 is L-shaped and has four sets on the carrier plate 2, which can provide lateral support for the carrier plate 2. The wear-resistant pad 103 can absorb vertical impact through elastic compression when it comes into contact with the mounting plate 1.

[0026] In this embodiment, the movable seat 301 is fixedly connected to the bottom of the carrier plate 2, and the reinforcing supports 101 are evenly distributed on the carrier plate 2.

[0027] In use, the guide sleeve 203 can restrict the position of the screw 202 to prevent it from shifting, ensure that the carrier plate 2 is evenly pressed against the rubber pad 201, enhance the vertical buffering effect, and guide the screw 202 to apply force vertically, thereby improving the installation stability of the PCB body 3.

[0028] In this embodiment, the end of the telescopic tube 104 away from the movable seat 102 is movably connected to the movable seat 2 301, and a spring 105 is sleeved on the outside of the telescopic tube 104.

[0029] When in use, the rubber pad 201 absorbs vertical impact force through elastic deformation under pressure, while the buffering properties of rubber reduce the rigid contact between the carrier plate 2 and the mounting plate 1, thereby enhancing the vibration reduction effect.

[0030] In this embodiment, a wear-resistant pad 103 is fixedly provided at the bottom of the reinforcing support 101, and a rubber pad 201 is fixedly provided at the bottom center of the carrier plate 2.

[0031] In use, the telescopic tube 104 enables flexible swinging, and combined with the elastic extension and contraction of the spring 105, it generates a reverse elastic force when the PCB body 3 is subjected to lateral or oblique impact, which offsets the impact force and resets the carrier board 2. At the same time, it can help absorb vertical vibration and form multi-directional buffer.

[0032] In this embodiment, the reinforcing brace 101 is connected to the side wall of the carrier plate 2 by screw 106, and screw 202 are evenly distributed on the carrier plate 2.

[0033] When in use, the main materials of the wear-resistant pad 103 and the rubber pad 201 are silicone rubber or neoprene rubber, which have good elasticity and aging resistance. When subjected to pressure, they can fully deform and absorb impact, and are not easy to harden and crack after long-term use.

[0034] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When installing the PCB body 3, the rubber pad 201 is first adhered to the bottom of the carrier plate 2, and the screw 202 is tightened with a tool and passes through the guide sleeve 203, thereby fixing the carrier plate 2 and the PCB body 3 to the mounting plate 1. At the same time, the rubber pad 201 is compressed and generates elastic deformation, making close contact with the surface of the mounting plate 1. During use, it can absorb and weaken some of the impact energy, and the guide sleeve 203 restricts the displacement of the screw 202, ensuring that the carrier plate 2 is subjected to uniform force. To enhance the buffering effect, the "L"-shaped reinforcing support 101 is connected and fixed to the side of the carrier plate 2 by screw 106. At the same time, the wear-resistant pad 103 is attached to the bottom of the reinforcing support 101 so that it contacts the mounting plate 1. When subjected to lateral force, the wear-resistant pad 103 first provides initial buffering, and then the telescopic tube 104 and spring 105 are stretched or compressed. The elastic force drives the carrier plate 2 to return to its original position, effectively offsetting the lateral impact. When subjected to vertical force, with the cooperation of the telescopic tube 104, the wear-resistant pad 103 and rubber pad 201 can further assist in absorbing vibration and improve the overall impact resistance of the PCB body 3.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
