Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

As shown in fig. 1 to 4, the durable printed wiring board according to the present embodiment includes a board body 1, a mounting block 2, and a seismic resistant member; the mounting blocks 2 are arranged on the two sides of the plate body 1; each mounting block is provided with a clamping groove 11 for assembling the plate body 1; the bottom of each mounting block is provided with the anti-seismic assembly; the anti-seismic assembly comprises a support rod 31, a support base 32 and an elastic component 4; an accommodating cavity 33 for accommodating the elastic component 4 is formed in the supporting base; the supporting base is also provided with a through hole 34 communicated with the accommodating cavity 33; the top end of the supporting rod 31 is connected with the bottom of the mounting block; the bottom end of the supporting rod 31 passes through the through hole 34 and then is connected with the elastic component 4; the support rod 31 is disposed on the support base through the elastic member 4.
Specifically, when the plate body 1 needs to be installed, only the two ends of the plate body 1 need to be respectively aligned to the inlets of the clamping grooves 11, then the plate body 1 is pushed, so that the plate body 1 is pushed along the inner side of the strip-shaped groove, after the plate body 1 is moved to a proper position, glue can be passed between the clamping grooves 11 and the plate body 1, and the clamping grooves 11 and the plate body 1 are firmly connected together. Due to the fact that the elastic component 4 is arranged at the bottom of the mounting block 2, when the plate body 1 receives external acting force, the supporting rod 31 is correspondingly pushed along with vibration of the plate body 1 to move downwards or upwards in the through hole 34 and the accommodating cavity 33, and due to the fact that the elastic component 4 is arranged in the process, the elastic component 4 deforms to absorb energy of the external acting force, and the shock absorption effect is achieved. Through setting up support base 32 and the through-hole 34 on the support base 32, can inject the movement track of bracing piece 31, the shock attenuation effect is better.
As shown in fig. 1 to 4, in the durable printed wiring board according to the present embodiment, the elastic member 4 includes a first inclined arm 41, a second inclined arm 42, a spring 43, and a pulley 44; the top end of the first inclined arm 41 and the top end of the second inclined arm 42 are respectively hinged with the bottom of the support rod 31; the first oblique arm 41 and the second oblique arm 42 form an inverted V-shaped structure; the spring 43 is arranged between the first inclined arm 41 and the second inclined arm 42; and both ends of the spring 43 are respectively connected with the first oblique arm 41 and the second oblique arm 42; the pulleys 44 are arranged at the bottom end of the first inclined arm 41 and the bottom end of the second inclined arm 42; the pulley 44 is slidably connected to the inner wall of the accommodating chamber 33.
Specifically, because the first inclined arm 41 and the second inclined arm 42 are in an inverted V-shaped structure, and the top end of the first inclined arm 41 and the top end of the second inclined arm 42 are hinged to the bottom of the supporting rod 31, when the plate body 1 is forced to be pressed downward, the two pulleys 44 move to the two ends under the action of external force, respectively, the distance between the first inclined arm 41 and the second inclined arm 42 becomes longer, the spring 43 is pulled away at this time, the spring 43 stores energy, and after the external force disappears, the spring 43 releases the capacity to pull the first inclined arm 41 and the second inclined arm 42 back by the spring 43, so as to drive the two pulleys 44 to move in opposite directions. Similarly, when the plate body 1 is in the ascending trend, the spring 43 absorbs the impact force and is extruded, the two pulleys 44 are driven by the spring 43 to move closely, and then the energy is released until the plate body 1 is stabilized, so that the buffering effect is good.
As shown in fig. 1 to 4, in the durable printed circuit board of the present embodiment, the inner wall of the accommodating cavity 33 is provided with a guiding chute 45; the pulley 44 is slidably connected to the guide chute 45.
The arrangement of the guide chute 45 can prevent the pulley 44 from irregularly moving in the accommodating cavity 33 when external acting force is received, so that the damping effect is not affected. Specifically, when the plate body 1 is forced by an external force and tends to be pressed downward, the two pulleys 44 move along the two ends of the guide chute 45 respectively under the action of the external force, the distance between the first inclined arm 41 and the second inclined arm 42 becomes longer, the spring 43 at the moment is pulled away, the spring 43 stores energy, and after the external force disappears, the spring 43 releases the capacity to pull back the first inclined arm 41 and the second inclined arm 42 by the spring 43, so that the two pulleys 44 are driven to move along the guide chute 45 in opposite directions. Similarly, when the plate body 1 is in the ascending trend, the spring 43 absorbs the impact force and is extruded, the two pulleys 44 are driven by the spring 43 to move closely, and then the energy is released until the plate body 1 is stabilized.
As shown in fig. 1 to 4, in the durable printed circuit board of the present embodiment, the supporting rod 31 is provided with a detachment prevention ring 46 for preventing the elastic member 4 from detaching from the accommodating cavity 33; the anti-drop ring 46 is positioned in the accommodating cavity 33; the diameter of the anti-slip ring 46 is larger than the diameter of the through hole 34.
During the process of receiving external vibration force, the supporting rod 31 will move up and down or swing slightly left and right in the through hole 34 along with the external force. When the external vibration force is too large, the bottom of the supporting rod 31 tends to be separated from the through hole 34, and if the anti-drop ring is not added, the elastic member 4 may be completely separated from the accommodating cavity 33, so that the plate body 1 collides with an unnecessary place to cause serious damage, or the elastic member 4 may be stuck to the through hole 34 and cannot be restored, thereby losing the damping effect and affecting the use.
As shown in fig. 1-4, in the durable printed circuit board of this embodiment, a flexible shock absorbing member is further disposed between the top of the supporting rod and the bottom of the mounting block.
The soft shock-absorbing member can be a common rubber pad for shock absorption, and can also be a shock-absorbing pad in the form of an air bag.
As shown in fig. 1 to 4, in the durable printed wiring board of the present embodiment, a heat dissipation member is provided on the bottom surface of the board body 1.
The heat dissipation effect can be enhanced by the arrangement.
As shown in fig. 1 to 4, in the durable printed circuit board of the present embodiment, the heat dissipation member includes a silicone pad 51 and a heat dissipation plate 52; the silicone pad 51 is disposed between the bottom surface of the plate body 1 and the heat dissipation plate 52.
The material of the silicone pad 51 may be common heat conductive silicone for adhering the heat dissipation plate 52 to the bottom of the board body 1. The silica gel pad 51 has good heat conduction effect.
As shown in fig. 1-4, in the durable printed circuit board of the present embodiment, the bottom surface of the heat dissipation plate 52 is provided with heat dissipation fins 53.
The heat dissipation fins 53 increase the heat dissipation area and accelerate the heat dissipation effect.
The above is only a preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the protection scope of the present invention.
