Abstract

The utility model relates to a position-limit mechanism for the drive installation, in particular to a position-limit mechanism for the intelligent bed drive installation which can automatically adjust the bed surface angle. The utility model overcomes the shortcoming of imprecision in position limitation with the position-limit mechanism of prior elevation beds. The technical scheme is that the position-limit mechanism of the intelligent bed drive installation includes a nut-screw push block and an initial-position, end-position travel switches; the nut-screw push block is connected with a turbo screw shaft; the turbo screw shaft is supported by bearing; the position-limit mechanism is arranged inside the housing formed by an upper case and a lower case, which is characterized in that the position-limit mechanism further comprises a travel assistant hitting block; the travel assistant hitting block mounted in the guide groove formed by the upper case and the lower case of the housing is linked with the screw-nut push block; the contact part between the travel assistant hitting block and the initial-position travel switch and end-position travel switch is a slope. The utility model is mainly used for limiting the ascending and descending position of the elevation bed.

Description

The position-limit mechanism of intelligence bed drive unit
One, technical field
The utility model relates to a kind of position-limit mechanism of drive unit, and more particularly, it relates to a kind of position-limit mechanism that can regulate the intelligence bed drive unit of bed surface angle within the specific limits automatically.
Two, background technology
Adjustable bed angles that adopt mechanical system to regulate bed surface of selling in the market more, not only time-consuming but also require great effort; Minority uses Vidacare corp to regulate, and often is attended by shortcomings such as spacing inaccurate or inefficacy again.It is spacing that Chinese patent ZL00252487.2 " electronic Wood spring health bed drive unit " directly contacts realization by slide block and stop, because the triggering stroke of stop is very little, therefore very high to the requirement on machining accuracy of each parts, as process improperly, be easy to cause spacing inaccurate or lost efficacy; In addition, screw mandrel makes mechanism comparatively numerous and diverse by bearing and guide pad together support.
Three, utility model content
The purpose of this utility model is to provide a kind of position-limit mechanism that can realize the intelligence bed drive unit that safety is spacing efficiently and accurately.
The technical solution of the utility model is: the position-limit mechanism of intelligence bed drive unit, comprise screw pushing block and initial bit, terminal position travel switch, the screw pushing block connects with the turbine screw axis that is connected with the motor turbine by screw thread, the worm gear screw axis is by bearings, position-limit mechanism is positioned at the housing of being made up of upper and lower covers, it is characterized in that: position-limit mechanism comprises that also stroke assists collision block, the auxiliary collision block of stroke is installed in the guiding groove of being made up of the housing upper and lower covers, drive interlock by the screw pushing block, auxiliary collision block of stroke and initial bit travel switch, the part of terminal position travel switch contact is the inclined-plane.
The beneficial effects of the utility model are: owing to settled stroke to assist collision block, its use can guarantee that initial bit travel switch and terminal position travel switch are in time triggered, and guarantees that safety is spacing accurately.Reach: 1, spacing accurately, security reliability is high; 2, the accuracy of manufacture require low, be easy to make and install.The intelligence bed drive unit of this position-limit mechanism is housed, has effective control bed surface and adjust the spacing characteristics such as accurately of angle, stable working, the random self-locking in position, safety.
Four, appended drawings is the utility model structural representation
Five, the specific embodiment
With reference to accompanying drawing, intelligence bed drive unit is mainly by formations such as housing lower cover 1, case top lid 2, bearing 3, motor worm 4, worm gear screw axis 5, screw pushing block 6, the auxiliary collision block 7 of stroke, initial bit travel switch 8, terminal position travel switch 9, push rod turning cylinders 10.Wherein, position-limit mechanism is made of the auxiliary collision block 7 of stroke, initial bit travel switch 8, terminal position travel switch 9 etc.Described motor worm 4 cooperates with worm gear on the worm gear screw axis 5, drives worm gear screw axis 5 and rotates, and makes screw pushing block 6 front and back rectilinear motions; The auxiliary collision block 7 of stroke is installed in the guiding groove of housing upper and lower covers composition, seesaws along worm gear screw axis 5 with screw pushing block 6; The auxiliary collision block 7 of stroke is the inclined-plane with the part that initial bit travel switch 8, terminal position travel switch 9 contact, and can guarantee effective triggering, and the triggering of avoiding causing because of reasons such as foozles was lost efficacy; Push rod turning cylinder 10 1 ends are installed on the bed surface, and the other end contacts with screw pushing block 6, and seesawing of screw pushing block 6 promotes 10 rotations of push rod turning cylinder, drive corresponding bed surface and rise or descend, thereby realize regulating the function of bed surface angle.

Claims (2)

1, the position-limit mechanism of intelligence bed drive unit, comprise screw pushing block and initial bit, terminal position travel switch, the screw pushing block connects with the turbine screw axis that is connected with the motor turbine by screw thread, the worm gear screw axis is by bearings, position-limit mechanism is positioned at the housing of being made up of upper and lower covers, it is characterized in that: position-limit mechanism comprises that also stroke assists collision block, and the auxiliary collision block of stroke is installed in the guiding groove of being made up of the housing upper and lower covers, is driven by the screw pushing block and links.
2, the position-limit mechanism of intelligence bed drive unit according to claim 1 is characterized in that: the auxiliary collision block of stroke is the inclined-plane with the part that initial bit travel switch, terminal position travel switch contact.
