Description
Technical field
The present invention relates to a kind of pillow, be specifically related to a kind of with the self-regulating pillow of pressure change in elevation.
Background technology
The people is when lying on one's side, since the shoulder supporting role, the height when requirement of pillow height is lain on the back.Generally promptly, need the pillow of two kinds of height because of the prone position conversion when people sleeps, can't regulate automatically but have the most height of pillow now.
Publication number is that the Chinese invention patent of CN101773350A discloses a kind of " damp type height automatic regulation pillow ", and through adopting damping mechanism, the height of pillow changes and can regulate automatically with pressure.Elevating movement was slowly soft when spiral damping mechanism had wherein guaranteed the pillow height variation.
Find in the practice that there is following shortcoming in above-mentioned spiral damping mechanism: in the process that the damping slide block slides along the hand of spiral, produce frictional noise between damping slide block and the damping slot in damping slot, influence pillow user ortho.
Summary of the invention
The present invention aims to provide a kind of damp type height automatic regulation pillow, is used to overcome the defective of existing pillow.Technical problem to be solved is, the first, and realize the slow soft of pillow lifting process and eliminate noise through new damping mode, require damping mechanism to take less space and reliable stablizing as far as possible.Damping mechanism had auxiliary positioning function when the second, pillow was in certain height.Three, the relative contact movement between damping mechanism and the side shield is more steady.
The present invention is that to solve the problems of the technologies described above the technical scheme that is adopted following:
A kind of damp type height automatic regulation pillow comprises that the rear end passes through connecting axle mutually hinged pillow frame and base plate, and described pillow frame rear side has backboard, also is provided with on the pillow frame with backboard and moves towards at least two vertical side retaining devices; Side retaining device and backboard surround the sunk part that is used to place pillow; Position near the pillow front end is equipped with damping mechanism, and this damping mechanism lower end is connected with base plate, and the upper end withstands on the side retaining device, it is characterized in that: described damping mechanism comprises spring(-supported) mount, between spring(-supported) mount and base plate, spring is installed; Hydraulic cylinder is installed in spring, and the bottom of hydraulic cylinder is connected with base plate, and piston is installed in the hydraulic cylinder, and the upper end of piston rod links to each other with spring(-supported) mount; Be provided with the oil storage cylinder sleeve of internal diameter in described hydraulic cylinder upper end greater than the hydraulic cylinder internal diameter; Described oil storage cylinder sleeve and the coaxial setting of hydraulic cylinder; The lower port of oil storage cylinder sleeve overlaps with the port of hydraulic cylinder and communicates; The port of oil storage cylinder sleeve is equipped with the oil sealing pedestal, in the oil sealing pedestal, is provided with oil sealing; Described piston rod passes described oil sealing pedestal and oil sealing; Vertical range between Oil sealing assembly lower surface and the hydraulic cylinder upper surface is less than the thickness of piston.
Described the axis of the piston is to offering spill port.
On the sidewall of hydraulic cylinder, radially offer the assist location hole of inner open outer end sealing, in this assist location hole, the assist location spring is installed, assist location spring the inner is equipped with the assist location ball; Correspondingly, on the lateral wall of piston, offer the draw-in groove that matches with described location ball.
The roller mount of band roller is installed in the upper surface of spring(-supported) mount; Correspondingly, on the baffle plate of side retaining device, offer roller track.
Good effect of the present invention is:
(1), the people when lying on one's side because the shoulder supporting role, head to the pressure of pillow less than supine position; Height when accordingly, the people lies on the back to the requirement of pillow height when lying on one's side.When the damping mechanism between pillow frame and the base plate receives big pressure, promptly under the supine position, the pillow height step-down; When the damping mechanism between pillow frame and the base plate receives less pressure, promptly lie on one's side under the state, pillow height uprises.Pillow height changes with spring stress to be regulated; But the restriction that this up-down is slided by the damping of piston in hydraulic cylinder also will; Therefore; Pillow goes up and down and to become slower, soft, and fast lifting fluctuated is to user's impact, particularly to the user's in the sleep impact in having avoided using.Realize the slow soft of pillow lifting process and because adopted hydraulic damping to eliminate noise.
(2), consider the restriction of the inner installation dimension of physiological structure characteristics and pillow of human body, described hydraulic damping mechanism should take few space of trying one's best, and therefore the external oil vessel can not be set.The present invention is equipped with the bigger oil storage cylinder sleeve of internal diameter above hydraulic cylinder, and requires vertical range between oil seal seat lower surface and the hydraulic cylinder upper surface less than the thickness of piston.The purpose of design is like this: when piston was in highest order, its lower surface was positioned at hydraulic cylinder and contacts with liquid, and upper surface and oil seal seat lower surface contact piston are limited; At this moment, the oil storage cylinder sleeve intracavity space around the piston becomes accumulator, when descent of piston; The liquid that piston and piston rod decline are discharged gets into described accumulator; Guaranteed that on the one hand therefore small and exquisite being convenient to of whole damping mechanism install, on the other hand, eliminated the idle stroke of piston operation; Realized the complete damping of piston running, guaranteed that can not occur beginning the damping of decline stage in the pillow lifting process lost efficacy.
Three, owing to set up the assist location mechanism of piston, when pillow was in certain height, when sleeping after the conversion sleeping position, damping mechanism had auxiliary positioning function, and pillow is in more stable state.
Four, the damping mechanism top is provided with roller, and the relative contact movement between damping mechanism and the side shield is steady more, resistance is littler.
