Description

Technical Field

[0001] This utility model relates to the field of circuit board mounting technology, and specifically to a support mechanism for circuit board mounting. Background Technology

[0002] A circuit board is made of insulating board as the base material, cut to a certain size, with at least one conductive pattern attached to it, and holes (such as component holes, fastening holes, metallization holes, etc.) to replace the chassis of the previous electronic components and realize the interconnection between electronic components.

[0003] Circuit boards used in environments with high-frequency vibration, such as engines, motors, fans, and pumps, may experience metal fatigue due to continuous micro-vibrations during prolonged use. This can eventually lead to fracture and failure of the solder joints (especially the bottom solder joints of BGA and QFN), affecting the lifespan of the circuit board. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solution: A support mechanism for circuit board mounting, comprising: a mounting frame and a buffer mounting module, wherein the mounting frame has a through mounting groove in the middle and positioning modules are provided on both sides of the mounting groove; the buffer mounting module includes a mounting base plate, a fixing base plate, and a buffer assembly; the mounting base plate is slidably disposed in the mounting groove; the fixing base plate is fixedly disposed at the lower end of the mounting base plate by the positioning modules; the buffer assembly is disposed between the mounting base plate and the fixing base plate; the mounting base plate has an assembly groove and a mounting screw; the assembly groove has an assembly assembly for mounting the circuit board; and the mounting screw has a mounting nut.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0016] Example 1 A support mechanism for mounting a circuit board includes: a mounting frame 1 and a buffer mounting module 2. The mounting frame 1 has a mounting groove 11 extending through its center, and positioning modules 12 are provided on both sides of the mounting groove 11. The buffer mounting module 2 includes a mounting base 21, a fixing base 22, and a buffer assembly 23. The mounting base 21 is slidably disposed in the mounting groove 11. The fixing base 22 is fixedly disposed at the lower end of the mounting base 21 by the positioning modules 12. The buffer assembly 23 is disposed between the mounting base 21 and the fixing base 22. The mounting base 21 has an assembly groove 211 and a mounting screw 212. An assembly assembly 213 for mounting a circuit board is disposed in the assembly groove 211. A mounting nut 2121 is disposed on the mounting screw 212.

[0017] like Figures 1-3 As shown, in actual use, the mounting frame 1 is first fixed in the target position to ensure the stability of the entire structure. Next, the circuit board is clamped by the assembly component 213. Then, the assembly component 213 is inserted into the assembly slot 211. At this time, the mounting screw 212 passes through the circuit board. After placement, the circuit board is fixed on the mounting screw 212 by the mounting nut 2121 to achieve fixed installation. Finally, the positioning module 12 positions the fixed substrate 22 to achieve the fixation of the buffer mounting module 2. The buffer component 23 can be a spring damping shock absorption mechanism to effectively prevent the circuit board from experiencing metal fatigue at the solder joints under high-frequency vibration, which could eventually lead to breakage and failure.

[0018] The modular design of this invention allows the circuit board to be installed on the buffer mounting module 2 first, and then fixed in the mounting frame 1 inside the equipment, avoiding the difficulties of installation in confined spaces. When inspecting or replacing the circuit board, disassembly can be completed simply by turning the mounting nut 2121, effectively reducing labor intensity.

[0019] As a further preferred embodiment, the assembly component 213 includes an upper mounting component 2131 and a lower mounting component 2132. The lower mounting component 2132 has a threaded portion 21321 at its upper end and a pin 21322 at its lower end. The threaded portion 21321 can be threadedly connected to the lower end of the upper mounting component 2131, and the pin 21322 is correspondingly provided with the assembly groove 211.

[0020] Specifically, the threaded portion 21321 can be threadedly connected to the lower end of the upper mounting member 2131 to achieve a secure connection between the upper mounting member 2131 and the lower mounting member 2132. The position of the insertion pin 21322 corresponds to the assembly slot 211 and is used to securely insert the lower mounting member 2132 into the assembly slot 211, ensuring that the entire assembly assembly 213 remains stable during installation, so that the assembly assembly 213 can effectively fix the circuit board while facilitating disassembly and adjustment.

[0021] As a further preferred embodiment, an adjusting screw 214 is rotatably provided at the lower end of the mounting base plate 21, and the lower end of the adjusting screw 214 is threadedly connected to the fixed base plate 22.

[0022] Specifically, by rotating the adjusting screw 214, the distance between the mounting base plate 21 and the fixed base plate 22 can be precisely adjusted, thereby achieving the adjustment of the buffer assembly 23 to adapt to different working conditions.

[0023] As a further preferred embodiment, a guide post 215 is provided between the mounting substrate 21 and the fixed substrate 22 to improve the stability between the mounting substrate 21 and the fixed substrate 22.

[0024] As a further preferred embodiment, the assembly components 213 are provided in four sets, and the four sets of assembly components 213 are provided at the four corners of the mounting base plate 21. The mounting screws 212 are provided in two sets, and the two sets of mounting screws 212 are provided between adjacent assembly components 213 and are symmetrically arranged.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
