Description
Technical Field
[0001] The utility model relates to the technical field of emergency communication equipment, in particular to a circuit board with rapid heat conduction and a portable emergency calling device. Background Art
[0002] A circuit board can be called a printed circuit board or a printed circuit board. The circuit board miniaturizes and visualizes the circuit, and plays an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. It is usually installed inside electrical equipment, such as in a portable emergency caller.
[0003] However, the circuit board will continue to generate heat when in use. This generated heat cannot be quickly dissipated from the device, so it will cause the chips and electronic components on the circuit board to heat up quickly, which will have a great impact on the life and working speed of the circuit board.
[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides a circuit board with rapid heat conduction and a portable emergency call device. Utility Model Content

[0009] Furthermore, two groups of negative pressure fans are fixedly installed inside the calling device, and the two groups of negative pressure fans are respectively located on the inner top wall and the bottom inner wall of the calling device. Through the two groups of negative pressure fans, after the heat generated by the operation of the circuit board is conducted by the heat conduction component, the heat can be quickly absorbed and discharged outside the calling device through the heat dissipation port, thereby playing a further role of heat conduction and heat absorption.
[0010] Furthermore, a slide groove is provided on the inner side wall of the calling device, a sliding sleeve rod is fixedly connected to the inner wall of the slide groove, a sliding block is sleeved on the outside of the sliding sleeve rod, and the end of the mounting plate is connected to the front side of the sliding block. The sliding block is arranged to move horizontally on the sliding sleeve rod, so that the mounting plate can be moved horizontally, so that the circuit board can be pulled out for quick maintenance, eliminating the tedious steps of disassembling the outer casing of the calling device.
[0011] Furthermore, a protrusion is fixedly connected to the center of the front side of the mounting plate, and two groups of limiting holes are opened on the surface of the protrusion. Through the provided protrusion and limiting holes, people can hook the limiting holes with their fingers and easily pull the mounting plate out from the inside of the calling device.
[0012] Furthermore, an inspection port is provided on the side of the calling device, and an opening and closing plate is hinged on the inner wall of the inspection port through a hinge.

[0015] 1. The utility model preliminarily improves the heat dissipation effect of the circuit board by setting the heat dissipation holes on the circuit board. Then the heat emitted by the circuit board is conducted through the heat conductive sheet and the thermal grease, and then is sucked out of the device from the heat dissipation port by the negative pressure fan, which achieves the effect of rapid heat dissipation and avoids the situation where the circuit board is easily damaged due to high temperature during use.
[0016] 2. The utility model provides a sliding block that moves horizontally on the sliding sleeve rod, so that the mounting plate can be moved horizontally, so that the circuit board can be pulled out of the calling device for quick maintenance, eliminating the tedious steps of disassembling the shell of the calling device and simplifying the maintenance work of people.

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a circuit board with rapid heat conduction and a portable emergency caller include a call device 1 and a circuit board 9. The top and bottom of the call device 1 are provided with heat dissipation ports 2. A mounting plate 6 is provided inside the call device 1. A plurality of heat conduction holes 8 are provided on the surface of the mounting plate 6. A heat conduction component 10 is movably installed on the surface of the mounting plate 6. The heat conduction component 10 includes a heat conduction sheet 1001. The bottom of the heat conduction sheet 1001 is coated with thermal grease 1002. A plurality of heat dissipation holes are provided on the surface of the circuit board 9. The heat dissipation effect of the circuit board 9 is initially improved by the heat dissipation holes provided on the circuit board 9. Subsequently, the heat emitted by the circuit board 9 can be effectively conducted through the heat conduction sheet 1001 and the thermal grease 1002, thereby further improving the heat dissipation effect of the circuit board 9. There are two groups of heat conduction components 10. The two groups of heat conduction components 10 are arranged on the circuit board 9. The two sides are symmetrically arranged, and the two groups of heat-conducting components 10 are arranged to have a good heat-conducting effect on the two sides of the circuit board 9, which is convenient for rapid heat discharge. Positioning sleeve rods 7 are fixedly connected at the four corners of the top of the mounting plate 6, and docking holes 1003 are provided at the four corners of the surface of the heat-conducting sheet 1001 and the circuit board 9. The docking holes 1003 are inserted into the docking holes 1003 through the arranged positioning sleeve rods 7, so that the heat-conducting component 10 and the circuit board 9 can be quickly assembled, and the disassembly and assembly are convenient. Two groups of negative pressure fans 11 are fixedly installed inside the calling device 1, and the two groups of negative pressure fans 11 are respectively located on the inner top wall and the bottom inner wall of the calling device 1. Through the two groups of negative pressure fans 11, after the heat-conducting component 10 conducts the heat generated by the operation of the circuit board 9, the heat can be quickly absorbed and discharged from the calling device 1 through the heat dissipation port 2, which plays a further heat conduction and heat absorption effect.
[0025] like Figure 1-5 The cam 5 is connected to the top of the support frame 1 and the bottom of the support frame 1 is connected to the top of the support frame 1, so that the cam 5 can be easily removed by the user.
[0026] A portable emergency call device is provided with a circuit board with rapid heat conduction as described above. The heat can be quickly conducted to the circuit board 9 through a heat conduction component 10, and then the heat is quickly absorbed by a negative pressure fan 11 and discharged outside the call device 1 through a heat dissipation port 2, thereby achieving an effective heat conduction and heat dissipation effect.
[0027] In summary, the circuit board with rapid heat conduction and the portable emergency call device are firstly based on Figures 1 to 5 In the structure shown in the figure, the heat generated by the circuit board 9 when in use can play a preliminary heat dissipation role through the heat dissipation holes on its surface, and then the heat is conducted through the heat conductive sheet 1001 and the thermal grease 1002, and then sucked out of the device from the heat dissipation port 2 by two sets of negative pressure fans 11, which has the effect of rapid heat dissipation. The two sets of heat conductive components 10 can play a good heat conductive role on both sides of the circuit board 9, which is convenient for the heat to be quickly discharged out of the call device 1. When the circuit board 9 needs to be inspected, the opening and closing plate 3 is flipped open by the hinge, and then the limit hole on the protrusion is hooked with a finger to pull it out. The mounting plate 6 moves horizontally on the sliding sleeve rod 4 through the sliding block 5 until it is pulled out of the outside of the call device 1, so that the circuit board 9 can be quickly inspected, eliminating the cumbersome steps of people disassembling the shell of the call device 1, and simplifying people's inspection work.
