Abstract
The utility model discloses flexible bearing structure of PWB, include: elastic support elements, the bottom plate, the bottom plate sets up the both ends of elastic component, the brace rod, brace rod one end with elastic support elements connects, in the slotted hole of brace rod other end embedding PWB board. Elastic support elements is the arc structure. Brace rod one end is connected the curved top of elastic support elements. The utility model discloses when flexible bearing structure of PWB made PWB fixed not hard up when the product tolerance accumulation, owing to set up the pre -compaction volume, the pre -compaction volume was greater than total tolerance accumulation, and the PWB board is still fixed compact, can not become flexible, make the PWB magnitude of interference more during the general orientation deviation, owing to designed elasticity arc -shaped strip column structure, permissible elastic deformation when product tolerance accumulation. Can not cause the installation difficulty.
Description
Technical field
This utility model relates to electronic applications, particularly relates to the rear cover supporting structure of electronic automobile meter, particularly a kind of PWB flexible support structure.
Background technology
In automobile electronics, instrument, towards driver, is extremely its important parts, fixing being typically all of the PWB plate in instrument does supporting construction compression, as it is shown in figure 1,1 is bonnet on bonnet, 1-1 is PWB board supporting structure on bonnet, and 2 is PWB plate, and 3 is lamp-box frame.PWB plate is fixed by lamp-box frame and rear cover supporting structure.But all there is dimensional tolerance due to product, so when limit deviation, it is possible to cause PWB to compress the magnitude of interference and cause greatly installation difficulty, or excesssive gap, cause PWB plate to loosen.
Utility model content
The purpose of this utility model be to provide a kind of can absorb each part manufacturing tolerance, the PWB flexible support structure that makes PWB reach good fixed effect.
For solving above-mentioned technical problem, this utility model PWB flexible support structure, including: elastic supporting member for supporting optical member；Base plate, described base plate is arranged on the two ends of described elastic component；Brace rod, described brace rod one end is connected with described elastic supporting member for supporting optical member, and the described brace rod other end embeds in the slotted eye of PWB plate.
Described elastic supporting member for supporting optical member is arcuate structure.
Described brace rod one end is connected to the top of described elastic supporting member for supporting optical member arc.
This utility model PWB flexible support structure is when product tolerance accumulation makes PWB fix loosening, and owing to being provided with precompressed amount, precompressed amount is more than total tolerance stack, and PWB plate is still fixed compact, will not loosen；When product tolerance accumulation makes the PWB magnitude of interference more general orientation deviation, owing to devising flexible arc list structure, elastic deformation can be allowed.Do not result in installation difficulty.
Accompanying drawing explanation
Fig. 1 is prior art construction schematic diagram；
Fig. 2 is this utility model PWB flexible support structure structural representation；
Fig. 3 is that this utility model PWB flexible support structure uses schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model PWB flexible support structure is described in further detail.
As shown in Figure 2 and Figure 3, the bottom of the brace rod 3 of this utility model PWB flexible support structure is connected on elastic supporting member for supporting optical member 1, then fixes with PWB plate 4 in the slotted eye (not shown) of the top embedding PWB plate 4 of brace rod 3.By brace rod 3, the power of PWB plate 4 and lamp-box frame 5 is delivered on base plate 2.Owing to elastic supporting member for supporting optical member 1 is arc, this just provides certain precompressed amount to brace rod 3, and when assembling, the elastic supporting member for supporting optical member 1 of arc can carry out elastic deformation to absorb tolerance.And brace rod 3 is provided in elastic supporting member for supporting optical member 1 top, the most RC position, just by power Transmit evenly suffered by himself to elastic supporting member for supporting optical member 1 and base plate 2, improve stability.
Below the preferred embodiment created this utility model is illustrated, but this utility model is not limited to embodiment, those of ordinary skill in the art also can make modification or the replacement of all equivalents on the premise of this utility model creative spirit, and modification or the replacement of these equivalents are all contained in scope of the present application.
