The utility model discloses take the theory of operation of back of the chair structure of electronic lift headrest: when the headrest lifting mechanism works, the motor drives the screw rod to rotate, the screw rod rotates to drive the headrest rod support to move along the axial direction of the screw rod, the headrest rod support is fixedly connected with the lower end of the headrest rod, and then the headrest rod is driven to lift and slide in the headrest rod guide sleeve, so that the headrest fixed on the upper portion of the headrest rod can lift, and operation and use are facilitated.
Description
The technical field is as follows:
the utility model relates to a back of chair structure of electrified lift headrest.
Background art:
the headrest can be used in seats of cars, but the conventional headrest is fixed in height or needs to be adjusted manually, so that the use is inconvenient.
The utility model has the following contents:
in view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a back of chair structure with electric lift headrest, this back of chair structure with electric lift headrest reasonable in design is favorable to convenient operation and use.
The utility model discloses take back of the chair structure of electronic lift headrest, its characterized in that: including establishing at the back of the chair internal and relative two back of the body skeletons that set up and fixed establish the horizontal pole between two back of the body skeletons, the fixed motor support board that is equipped with on the horizontal pole and two headrest pole guide pin bushings of establishing in motor support board both sides, the cover is equipped with the gliding headrest pole of headrest pole guide pin bushing relatively on two headrest pole guide pins, the lower tip of headrest pole is fixed to be equipped with headrest pole pillow and holds in the palm, fixed motor and by motor drive pivoted lead screw that is equipped with in the motor support board, the lead screw spiro union is in the screw at headrest pole pillow support middle part.
Furthermore, the free end of the screw rod is rotatably hinged on a turning plate at the lower part of the motor supporting plate.
Further, the headrest rods are in an inverted U shape.
The utility model discloses take the theory of operation of back of the chair structure of electronic lift headrest: when the headrest lifting mechanism works, the motor drives the screw rod to rotate, the screw rod rotates to drive the headrest rod support to move along the axial direction of the screw rod, the headrest rod support is fixedly connected with the lower end of the headrest rod, and then the headrest rod is driven to lift and slide in the headrest rod guide sleeve, so that the headrest fixed on the upper portion of the headrest rod can lift, and operation and use are facilitated.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Description of the drawings:
FIG. 1 is a perspective view of a chair back structure with an electric headrest;
FIG. 2 is a perspective view of another station of the chair back structure with an electrically-actuated lift headrest of the present invention;
fig. 3 is a partial view of fig. 1.
The specific implementation mode is as follows:
in order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The utility model discloses a chair back structure with electric lift headrest comprises two back frameworks 1 which are arranged in the chair back body and are oppositely arranged and a cross bar 2 which is fixedly arranged between the two back frameworks, a motor supporting plate 3 and two headrest rod guide sleeves 4 which are fixedly arranged at two sides of the motor supporting plate are fixedly arranged on the cross bar 2, a headrest rod 5 which can slide relative to the headrest rod guide sleeves 4 is sleeved on the two headrest rod guide sleeves 4, a headrest rod pillow support 6 is fixedly arranged at the lower end part of the headrest rod 5, a motor 7 and a screw rod 8 which is driven by the motor to rotate are fixedly arranged on the motor supporting plate 3, the screw rod 8 is screwed in a screw hole at the middle part of the headrest rod pillow support 6, wherein the back frameworks 1 can be stainless steel frames, the shapes of the back frameworks can be triangular, the structure is more stable, a plurality of straight rods or optical axes can be arranged between the two back frameworks 1, one of the straight rods or the optical axes is taken as the cross bar, the cross bar can be welded with a motor support plate 3 and a headrest rod guide sleeve 4.
The headrest rod support 6 can be a rectangular block made of metal or plastic, a screw hole for screw connection of the screw rod is formed in the middle of the headrest rod support, counter bores 10 are formed in the two side portions of the headrest rod support, and the two lower end portions of the headrest rod 5 are in interference fit with the counter bores, so that the headrest rod 5 and the headrest rod support 6 are fixed.
Furthermore, in order to design reasonably, the free end of the screw rod 8 is rotatably hinged on the turning plate 9 at the lower part of the motor support plate, and the free end of the screw rod 8 is rotatably hinged on the turning plate 9, so that the work of the screw rod is more stable and reliable, specifically, the free end of the screw rod 8 is sleeved on a through hole of the turning plate 9 in a clearance mode, and nuts are locked on the upper part and the lower part of the turning plate 9.
Furthermore, for reasonable design, the headrest rod is in an inverted U shape, the structure of the headrest rod is more stable and reliable, a headrest can be arranged at the upper part of the headrest rod, and the two sides of the headrest rod are provided with polished rods which are in clearance fit with the headrest rod guide sleeve 4, so that smooth sliding can be realized.
The utility model discloses take the theory of operation of back of the chair structure of electronic lift headrest: when the headrest lifting mechanism works, the motor drives the screw rod to rotate, the screw rod rotates to drive the headrest rod support to move along the axial direction of the screw rod, the headrest rod support is fixedly connected with the lower end of the headrest rod, and then the headrest rod is driven to lift and slide in the headrest rod guide sleeve, so that the headrest fixed on the upper portion of the headrest rod can lift, and operation and use are facilitated.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
