Description

Technical Field

[0001] This utility model relates to the field of printed circuit board technology, and in particular to a printed circuit board with a shock-absorbing structure. Background Technology

[0002] Printed circuit boards (PCBs) are the providers of electrical connections for electronic components. They can be classified according to the number of layers, such as single-sided boards, double-sided boards, four-layer boards, six-layer boards, and other multi-layer circuits.

[0003] A printed circuit board with a shock-absorbing structure is disclosed in publication number "CN212463619U". The printed circuit board body has a soft pad on its upper surface, and a protective plate is fixedly connected to the upper surface of the soft pad. Limiting rods are fixedly connected to the four corners of the lower surface of the protective plate, and springs are sleeved on the surface of the limiting rods. The top and bottom ends of the springs are fixedly connected to the lower surface of the protective plate and the lower surface of the inner wall of the slot, respectively. This shock-absorbing printed circuit board, by setting up the protective plate, limiting rods, springs, slots, fixing seats, and protrusions, allows the four protrusions to position the printed circuit board body during transportation. Simultaneously, the printed circuit board body can eliminate vibration impulses by compressing the springs, utilizing the spring's extension and contraction characteristics to achieve a shock-absorbing effect, thereby reducing the damage caused by vibration to the printed circuit board body.

[0004] While this solution can alleviate the vibration experienced by the circuit board, it requires a lot of space and is not easy to disassemble, increasing the cost of use. Furthermore, the circuit board needs to be unloaded after transportation, which is difficult with this solution. Therefore, improvements are needed. Utility Model Content

[0058] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a printed circuit board with a shock-absorbing structure.

[0059] A printed circuit board with a shock-absorbing structure includes a support block 1 and a support groove 2, the support groove 2 being formed within the support block 1; it also includes: a support frame 3, disposed within the support groove 2 and slidably connected to the support groove 2; a lifting mechanism, disposed within the support groove 2, for lifting the support frame 3; and an elastic mechanism, disposed on the lifting mechanism, for shock absorption of the printed circuit board.

[0060] Reference Figure 4 The lifting mechanism includes: a first lifting shaft 4, which is mounted on the support block 1 and rotatably connected to the support block 1; a lifting plate 5, which is mounted on the first lifting shaft 4 and fixedly connected to the first lifting shaft 4; a second lifting shaft 6, which is fixedly connected to the lifting plate 5; a lifting sleeve 7, which is rotatably connected to the second lifting shaft 6; and a rotating component, which is mounted in the support groove 2.

[0061] This configuration allows the rotating lifting sleeve 7 to rotate the lifting plate 5, which is fixedly connected to the second lifting shaft 6, causing the first lifting shaft 4, which is fixedly connected to the lifting plate 5, to rotate on the support block 1, thereby driving the rotating components to operate.

[0062] Reference Figure 4 In a preferred embodiment, the rotating component includes: a plurality of rotating blocks 8, which are evenly arranged in the support groove 2 and fixedly connected to the support groove 2; a rotating groove 9, which is formed on the rotating blocks 8; a first rotating rod 10, which is disposed in the rotating groove 9, slidably connected to the rotating groove 9, and rotatably connected to the first lifting shaft 4; a second rotating rod 11, which is slidably connected to the rotating groove 9 and rotatably connected to the first lifting shaft 4; and a transmission component, which is disposed on the first rotating rod 10.

[0063] This configuration allows the first rotating rod 10 and the second rotating rod 11, which are rotatably connected to the first lifting shaft 4, to rotate, causing the first rotating rod 10 and the second rotating rod 11 to slide within the rotating groove 9 on the rotating block 8, thereby driving the transmission components to operate.

[0064] Reference Figure 4 In a preferred embodiment, the transmission component includes: a plurality of first transmission plates 12, which are evenly disposed on a first rotating rod 10 and rotatably connected to the first rotating rod 10; a plurality of second transmission plates 13, which are evenly disposed on a second rotating rod 11 and rotatably connected to the second rotating rod 11; a transmission shaft 14, which is disposed on the first transmission plates 12 and rotatably connected to the first transmission plates 12, and rotatably connected to the second transmission plates 13; and a sliding component, which is disposed on the first transmission plates 12.

[0065] This configuration causes the first transmission plate 12, which is rotatably connected to the first rotating rod 10, to rotate, and the second transmission plate 13, which is rotatably connected to the second rotating rod 11, to rotate, thereby driving the sliding component to run.

[0066] Reference Figure 4 In a preferred embodiment, the sliding component includes: a first sliding shaft 15, disposed on the first transmission plate 12 and rotatably connected to the first transmission plate 12; a second sliding shaft 16, rotatably connected to the second transmission plate 13; a sliding block 17, disposed on the first sliding shaft 15, slidably connected to the first sliding shaft 15 and slidably connected to the second sliding shaft 16; and a sliding plate 18, fixedly connected to the sliding block 17 and slidably connected to the support groove 2.

[0067] This configuration allows the first sliding shaft 15, which is rotatably connected to the first transmission plate 12, to slide within the sliding block 17, and the second sliding shaft 16, which is rotatably connected to the second transmission plate 13, to slide within the sliding block 17. This, in turn, allows the sliding plate 18, which is fixedly connected to the sliding block 17, to slide within the support groove 2, thereby enabling the support frame 3 to be raised and lowered.

[0068] Reference Figure 5 In a preferred embodiment, the elastic mechanism includes: a plurality of first elastic frames 19, which are evenly arranged on the sliding plate 18 and detachably fixedly connected to the sliding plate 18; a spring 20, which is fixedly connected to the first elastic frames 19; a second elastic frame 21, which is fixedly connected to the spring 20 and fixedly connected to the support frame 3; and a connecting component, which is disposed on the second elastic frame 21.

[0069] This configuration causes the second elastic frame 21, which is fixedly connected to the support frame 3, to move closer to the first elastic frame 19, thereby compressing the spring 20, which is fixedly connected to the first elastic frame 19 and the second elastic frame 21, generating elastic potential energy and driving the connecting components to move.

[0070] Reference Figure 5 In a preferred embodiment, the connecting component includes: a plurality of first connecting shafts 22, which are evenly arranged on the second elastic frame 21 and fixedly connected to the second elastic frame 21; a first connecting plate 23, which is rotatably connected to the first connecting shafts 22; a second connecting shaft 24, which is rotatably connected to the first connecting plate 23; a second connecting plate 25, which is rotatably connected to the second connecting shaft 24; and a third connecting shaft 26, which is fixedly connected to the first elastic frame 19 and rotatably connected to the second connecting plate 25.

[0071] This configuration allows the first connecting plate 23, which is rotatably connected to the first connecting shaft 22, to rotate, and the second connecting plate 25, which is rotatably connected to the second connecting shaft 24, to rotate around the axis of the third connecting shaft 26, thereby buffering the vibration generated by the circuit board.

[0072] Working principle: In use, the circuit board is first placed in the support frame 3. When the circuit board needs to be moved or unloaded, the lifting sleeve 7 is rotated, which drives the lifting plate 5, which is fixedly connected to the second lifting shaft 6, to rotate. This causes the first lifting shaft 4, which is fixedly connected to the lifting plate 5, to rotate on the support block 1, thereby driving the first rotating rod 10 and the second rotating rod 11, which are rotatably connected to the first lifting shaft 4, to rotate. This causes the first rotating rod 10 and the second rotating rod 11 to slide in the rotating groove 9 on the rotating block 8, thereby driving the first transmission plate 12, which is rotatably connected to the first rotating rod 10, to rotate. This causes the second transmission plate 13, which is rotatably connected to the second rotating rod 11, to rotate, thereby driving the first sliding shaft 15, which is rotatably connected to the first transmission plate 12, to slide in the sliding block 17, and the second sliding shaft 16, which is rotatably connected to the second transmission plate 13, to slide in the sliding block 17. This causes the sliding plate 18, which is fixedly connected to the sliding block 17, to slide in the support groove 2, thereby realizing the lifting and lowering of the support frame 3.

[0073] When the circuit board is transported over a bumpy road, the support frame 3 slides into the support groove 2 under the weight of the circuit board, causing the second elastic frame 21, which is fixedly connected to the support frame 3, to move closer to the first elastic frame 19. This compresses the spring 20, which is fixedly connected to the first elastic frame 19 and the second elastic frame 21, generating elastic potential energy. This causes the first connecting plate 23, which is rotatably connected to the first connecting shaft 22, to rotate, and the second connecting plate 25, which is rotatably connected to the second connecting shaft 24, to rotate around the axis of the third connecting shaft 26, thereby buffering the vibration generated by the circuit board.

[0074] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
