[0028] The present invention will be described in further detail below with reference to the accompanying drawings.
[0029] like Figure 1 、 Figure 2 、 Figure 3 As shown, a shock-resistant PCBA motherboard includes a motherboard body 1, a base plate 2, a sliding tube 3, a sliding rod 4, a sliding plate 5, a first spring 6, a second spring 7 and a mounting seat 8.
[0030] like Figure 1 、 Figure 2 、 Figure 3 As shown, the main body 1 is arranged horizontally as a whole, and four bottom plates 2 are provided, which are arranged horizontally below the four corners of the main body 1. Sliding tubes 3 are vertically arranged on the bottom plates 2, and sliding rods 4 are vertically slidably connected to the sliding tubes 3. Sliding plates 5 are arranged at the lower ends of the sliding rods 4 and abut the inner walls of the sliding tubes 3 on all sides.
[0031] like Figure 1 、 Figure 2 、 Figure 3 As shown, the first spring 6 is arranged in the sliding tube 3 and is located between the sliding plate 5 and the bottom plate 2. The second spring 7 is sleeved on the outer wall of the sliding rod 4 and is located between the sliding plate 5 and the top wall of the sliding tube 3. Therefore, when the main board body 1 moves downward, the first spring 6 provides elastic support, and when the main board body 1 moves upward, the second spring 7 provides elastic support.
[0032] like Figure 1 、 Figure 2 、 Figure 3 As shown, the mounting seat 8 is provided at the upper end of the sliding rod 4 and is used to fix the four corners of the mainboard body 1 . The mounting seat 8 includes a seat plate 81 , a blocking bar 82 and a locking member 84 .
[0033] like Figure 1 、 Figure 2 、 Figure 3As shown, a seat plate 81 is horizontally mounted on the sliding rod 4. L-shaped stop bars 82 are positioned at the edges of the seat plate 81 and serve to clamp the two sides of the main body 1. Rubber pads 83 are installed on the surface of the seat plate 81 and the inner sidewalls of the stop bars 82 to enhance shock absorption at the connection point. The seat plate 81 is rotatably connected to the sliding rod 4, allowing for easy adjustment of the angle and position of the stop bars 82 on the seat plate 81.
[0034] like Figure 1 、 Figure 2 、 Figure 3 As shown, a locking member 84 is provided on the base plate 81 and is used to fix the main body 1. The locking member 84 includes a locking rod 85 and a hook 86. The locking rod 85 is vertically provided on the base plate 81 and is used to pass through the four corners of the main body 1. The hook 86 is provided at the upper end of the locking rod 85 and is used to press the upper end surface of the main body 1.
[0035] Therefore, when the circuit board is installed and used, the base plate 2 can be fixed to the component with screws or glue, and then the seat plate 81 can be controlled to rotate, and the angle and position of the baffle 82 on the seat plate 81 can be adjusted. Then, the main board body 1 can be placed on the four seat plates 81, and the baffle 82 on the seat plate 81 can clamp the four sides of the main board body 1.
[0036] At the same time, the locking rod 85 and the hook 86 pass through the holes at the four corners of the main board body 1, and the hook 86 presses the upper end surface of the main board body 1 to achieve the clamping and fixing of the main board body 1, completing the installation and fixing of the entire circuit board.
[0037] At the same time, when in use, no matter whether the mainboard body 1 is subjected to an upward or downward force, the first spring 6 or the second spring 7 serves as elastic support, providing excellent shock-resistant buffering performance for the circuit board, thereby avoiding damage to the circuit board due to vibration.
[0038] like Figure 1 、 Figure 2 As shown, a support frame 9 is cross-arranged below the main board body 1, and the end of the support frame 9 is fixed to the outer wall of multiple sliding tubes 3 to achieve connection between the multiple sliding tubes 3, increase the stability of the sliding tubes 3 during operation, and ensure the stable operation of the circuit board.
[0039] like Figure 1 、 Figure 2 As shown, a rubber column 91 is vertically set in the middle position of the support frame 9 to resist the lower end surface of the mainboard body 1. On the one hand, it can support the middle position of the mainboard body 1, and on the other hand, it can improve the seismic buffering performance of the middle position of the mainboard body 1.
[0040] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
