Description

Technical Field

[0002] Circuit boards are an indispensable key component in modern electronic devices. They are made of conductive materials, such as copper foil, and are formed into circuit patterns through processes such as etching. Circuit boards provide a platform for the installation and connection of various electronic components, enabling them to work together to achieve specific functions of electronic devices. The design and manufacture of circuit boards require precise technology and strict quality control. Its performance directly affects the stability, reliability and performance of the entire electronic device. In the development of electronic products, circuit boards continue to evolve and innovate to meet increasingly complex functional requirements.

[0003] During use, circuit boards are mostly installed inside electronic devices. When the electronic device vibrates during operation, the circuit board will also vibrate along with the electronic device. Long-term vibration can easily cause the electronic components of the circuit board to loosen, thereby affecting the use of the circuit board. At the same time, current flows in the electronic components on the surface of the circuit board, and the electronic components will generate a certain amount of heat. The existing heat dissipation method is mostly to blow air directly to the surface of the circuit board. In this heat dissipation method, the airflow can only contact one side of the circuit board, and the heat dissipation effect is poor, which is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] Example 1

[0024] like Figure 1-5 As shown, the utility model provides a shockproof circuit board, including a shock absorbing mechanism 1, a heat dissipation mechanism 2 is sleeved on the top of the shock absorbing mechanism 1, a circuit board 3 is slidably connected to the inner wall of the shock absorbing mechanism 1, the shock absorbing mechanism 1 includes a mounting plate 11, a mounting box 12 is fixedly connected to the top of the mounting plate 11, a limiting groove 13 is fixedly connected to the inner wall of the mounting box 12, a heat dissipation port 14 is arranged at one end of the mounting box 12, a fixing block 15 is fixedly connected to the bottom of the inner cavity of the mounting box 12, a damper 16 is fixedly connected to the inner wall of the fixing block 15, a spring 18 is movably sleeved on the surface of the damper 16, one end of the spring 18 is fixedly connected to the inner wall of the fixing block 15, the other end of the spring 18 is fixedly connected to a push block 17, and the side of the push block 17 close to the spring 18 is fixedly connected to one end of the damper 16.

[0025] In this embodiment, the spring 18 is compressed under the action of the push block 17, so that the spring 18 stores the kinetic energy generated during vibration. When the spring is subsequently extended, the kinetic energy stored in the spring 18 is consumed under the action of the damper 16, thereby achieving a shock-absorbing effect, thereby preventing the electronic components on the surface of the circuit board 3 from loosening due to vibration.

[0026] Example 2

[0027] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the heat dissipation mechanism 2 includes a box cover 21, the top of the box cover 21 is fixedly connected to a protective cover 22, the inner wall of the protective cover 22 is fixedly connected to a blower assembly 23, the lower end of the inner cavity of the box cover 21 is socketed with the top of the installation box 12, the lower end of the inner cavity of the protective cover 22 is fixedly connected to a filter screen 24, and a wire inlet 25 is opened on one side of the inner cavity of the box cover 21.

[0028] In this embodiment, during use, the outside air is sucked into the protective cover 22 through the air blowing assembly 23, and after being filtered by the filter 24 to remove dust in the air, it is blown to the surface of the plate body 32. Under the action of the airflow, the heat generated by the electronic components is taken away. At the same time, the setting of the ventilation holes 33 allows the airflow to enter the installation box 12 along the ventilation holes after contacting the front of the plate body 32, and contact the bottom surface of the fixing plate 31. Under the high thermal conductivity of the aluminum plate, the bottom surface of the plate body 32 is dissipated, so that it can dissipate heat on both sides of the plate body at the same time, and the heat dissipation mechanism is better and more convenient to use.

[0029] Example 3

[0030] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the circuit board 3 includes a fixed plate 31, the top bolts of the fixed plate 31 are connected to the plate body 32, the two sides of the fixed plate 31 are fixedly connected to sliding blocks 36, the surface of the sliding block 36 is slidably connected to the inner wall of the limiting groove 13, the fixed plate 31 is made of aluminum plate, a ventilation hole 33 is opened at one end of the fixed plate 31, the bottom of the fixed plate 31 is fixedly connected to a fixing rod 34, the bottom of the fixing rod 34 is fixedly connected to a pressing block 35, and the surface of the pressing block 35 overlaps the surface of the pushing block 17.

[0031] In this embodiment, when an electronic device using this circuit board vibrates, under the action of the vibration, the fixed plate 31 drives the sliding block 36 to reciprocate up and down along the limiting groove 13. During the movement, the fixed plate 31 moves downward so that the fixed rod 34 pushes the pressing block 35 to move downward, and then the pressing block 35 pushes the pushing block 17 to move.

[0032] The following is a detailed description of the working principle of the shockproof circuit board.

[0033] like Figure 1-5As shown, when the electronic device using the circuit board vibrates, under the action of the vibration, the fixed plate 31 drives the sliding block 36 to reciprocate up and down along the limiting groove 13. During the movement, the fixed plate 31 moves downward to make the fixed rod 34 push the pressing block 35 to move downward, and then the pressing block 35 pushes the pushing block 17 to move. Under the action of the pushing block 17, the spring 18 is compressed, so that the spring 18 stores the kinetic energy generated by the vibration. Then, when the spring stretches, under the action of the damper 16, the kinetic energy stored in the spring 18 is consumed, and the shock absorbing effect is achieved, so as to avoid the circuit board 3 from being damaged. The vibration causes the electronic components on the surface to loosen. At the same time, during use, the outside air is sucked into the protective cover 22 through the air blowing assembly 23, and after being filtered by the filter 24 to remove dust in the air, it is blown to the surface of the plate body 32. Under the action of the airflow, the heat generated by the electronic components is taken away. At the same time, the setting of the ventilation holes 33 allows the airflow to enter the installation box 12 along the ventilation holes after contacting the front of the plate body 32, and contact the bottom surface of the fixing plate 31. Under the high thermal conductivity of the aluminum plate, the bottom surface of the plate body 32 is dissipated, so that it can dissipate heat on both sides of the plate body at the same time, and the heat dissipation mechanism is better and more convenient to use.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
