Description

Supporting structure of fastener

Technical Field

The utility model relates to a bearing structure of fastener, in particular to fastener bearing structure that can avoid the screw to drag power.

Background

The screw usually serves as a connecting piece to connect and fix two objects into a whole, when the screw is locked, if the strength and rigidity of one object are poor and the flatness of the contact surface of the two objects is different, in order to lock the two objects into a whole, the screw tends to pull the object with lower strength and rigidity against the object with higher strength and rigidity, and in the pulling process, the object with lower strength and rigidity is deformed or broken due to pulling, so that the object is damaged, and the use function of the object is affected. Vehicle-mounted instruments, including instruments, navigation and the like, generally adopt a liquid crystal display screen, are limited by the imaging principle of the liquid crystal display screen, and are easy to cause uneven imaging brightness due to slight stress deformation, which is technically called as "MURA". Meanwhile, the display screen of the vehicle-mounted instrument tends to be large in size, and the larger the size of the liquid crystal display screen is, the more obvious the MURA caused by stress deformation generated by fixing of the fastening piece is. The vehicle-mounted display screen is usually heavy, and can meet the high experimental requirements of vibration, mechanical impact and the like, the vehicle-mounted liquid crystal display screen is fixedly fixed on the support body, and when the matching surface of the liquid crystal display screen is inconsistent with the flatness of the matching surface of the support body, the liquid crystal display screen is fixedly fixed, so that the liquid crystal display screen is deformed inevitably, thereby causing 'MURA' and influencing the display effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a fastener bearing structure who takes place to warp when can avoiding the display screen to pass through the screw-up to avoid MURA's emergence, guarantee the display effect of display screen.

Support structure of fastener, including the supporter, be provided with a plurality of mounting holes on the supporter, all install the buffering body in every mounting hole department, the buffering body includes fixed part and the portion of floating, and its fixed part fixed mounting is in mounting hole department, and the portion of floating then can float install in the inboard of fixed part, is connected through the elastic component between its and the fixed part, sets up the fastener mounting hole again in the centre of the portion of floating.

Bearing structure of fastener, when the installation is fixed, liquid crystal display installs on the supporter, the fastener passes the mounting hole in the middle of the floating part, is fixed in the supporter on the installation basic member. When the surface does not flatly receive the power of dragging of fastener, the fixed part relatively of floating portion takes place to float, changes its position in order to adapt to the installation demand to avoided the deformation of supporter, just also avoided installing the deformation of the liquid crystal display on the supporter, therefore can avoid MURA's emergence, guarantee liquid crystal display's effect.

Detailed Description

The utility model provides a bearing structure of fastener for on-vehicle instrument liquid crystal display's is fixed, as shown in fig. 1-2, includes supporter 1, is provided with a plurality of mounting holes 2 on the supporter 1 back, all installs buffer 3 in every mounting hole 2 department, buffer 3 include with fixed part 31 and unsteady portion 32, its fixed part 31 fixed mounting is on the pore wall of mounting hole 2, unsteady portion 32 then is located the inboard of fixed part 31, through the connection that elastic component 33 can float between its and fixed part 31 on the fixed part, then sets up screw mounting hole 9 in the centre of unsteady portion 32. The elastic member may be a deformable flexible plate such as a corrugated plate.

During the installation, screw 4 passes the screw mounting hole 9 and the supporter mounting hole 2 of the buffering body in proper order, screws buffering body 3 on the foundation structure 5 of supporter 1, can realize on-vehicle instrument liquid crystal display's fixed. Be provided with the elastic component between the floating part of its screw fixation direct contact and the fixed part of joint support body, consequently the power of dragging that the floating component received absorbs through the deformation of elastic component, and can not resume the transmission for the fixed part, just can not transmit on installation liquid crystal display's the supporter yet to can effectually avoid dragging the liquid crystal display that the power leads to because of the screw and warp, avoid MURA's emergence, guarantee liquid crystal display's effect.

The fixing portion of the buffer body may be fixed at the mounting hole 2 by a snap structure, as shown in fig. 2. The buffer body can also be fixed at the mounting hole through threaded mounting or fixed through welding.

The buckling structure, as shown in fig. 2 and 3, may include a plurality of claws 7 extending along the axial direction of the mounting hole on the annular substrate 6 and the annular substrate located on the upper side of the mounting hole, the claws are arranged at intervals along the circumferential direction of the annular substrate 6, and the buffer body is fixed at the mounting hole 2 from both ends through the protrusions 8 at the end portions of the annular substrate 6 and the claws 7.

The annular base plate still sets up two above risers 12 in the jack catch interval, and the riser extends along mounting hole axial direction equally, and its one end is integrative with annular base plate, and the other end freely extends in the mounting hole, and unsteady portion 32 is located the inboard of riser, and the outer wall of unsteady portion passes through connecting plate 33 and is connected with the free end of each riser simultaneously. But it has realized the floating connection between floating portion and the fixed part through riser and connecting plate.

The fixing part can be firmly clamped and fixed at the mounting hole of the supporting body through the annular base plate and the clamping claws, and the floating part is connected with the free end part of the outer side vertical plate through the connecting plate. When the floating part is compressed tightly on the basic structural member through the screw and is pulled by the screw, the vertical plate freely extending in the mounting hole outside the floating part can be deformed adaptively to absorb the pulling force, so that the deformation of the support body can be avoided.

As shown in figure 3, the clamping jaws can be uniformly distributed in the mounting holes, a vertical plate is arranged in the interval between every two adjacent clamping jaws, and the outer wall of the floating part is respectively provided with a connecting plate connected with the four vertical plates. The vertical plates arranged in four directions can better absorb the deformation in different directions, so that the deformation of the support body is better avoided.
