Description
Technical field
The utility model headrest of chair electricpropulsion installation relates to back frame, the headrest frame especially on office chair backrest.
Background technology
Going and seeking refuge with on existing back frame is generally divided into fixed and movable.Fixed head rest and back are fixed together, and its height and angle of inclination can not adjust, and thus also namely can not adjust according to end user's individual difference, use also uncomfortable.Movable head rest is flexibly connected with back, the mode generally adopted is plug-in, back there are two jacks, head rest there are two plungers, end user can adjust the height of head rest according to the depth inserted, for convenience of gland by being generally provided with stationary point or staying groove on two plungers.Although movable head rest can adjust the height of going and seeking refuge with, but need to adjust according to prediction in advance, forecasting inaccuracy end user will get up and again adjust, bother very much, simultaneously because plug needs expend muscle power, adjustment is got up also very hard, therefore still can bring inconvenience to end user.
Utility model content
The purpose of this utility model is to provide a kind of headrest of chair electricpropulsion installation, utilize additional power source can adjust height, the front and rear angles of head rest very convenient, freely, allow end user use sensation as snug as a bug in a rug, head rest adjustment is got up also very easy, freely.
The technical solution of the utility model, headrest of chair electricpropulsion installation, is characterized in that comprising: electric plating propulsion, the propeller that this electric plating propulsion comprises motor and is connected with motor output shaft; For the headrest frame that mounting head is leaned on, this headrest frame also comprises for fixing angle of rake pedestal, is fixed on the left axis of travel of symmetrical installation on this headrest frame and right axis of travel; Be fixed on the fixed mount of back, this fixed mount comprises the support plate for fixing motor, the left groove of accommodating left axis of travel and the right groove of accommodating right axis of travel.
Above-mentioned headrest of chair electricpropulsion installation, described headrest frame is longitudinally curved, described left groove and right groove is all curved matches with headrest frame arc.
Above-mentioned headrest of chair electricpropulsion installation, the upper end of described headrest frame is erection part.
Above-mentioned headrest of chair electricpropulsion installation, the upper end of described headrest frame is kink.
Above-mentioned headrest of chair electricpropulsion installation, described motor output shaft is thread spindle, and propeller internal fixtion has the thread plate be connected with this thread spindle.
Adopt technique scheme, end user can be sitting in chair only needs press the height and angle that motor switch can be adjustable headrest of chair.Motor can drive headrest frame to move up and down in the groove of fixed mount by propeller, thus realizes moving up and down of head rest.

Fig. 1 is the utility model headrest of chair electricpropulsion installation embodiment one schematic diagram.
Fig. 2 is exploded view shown in Fig. 1.
Fig. 3 is the A-A of electric plating propulsion shown in Fig. 2 sectional view.
Fig. 4 is the utility model headrest of chair electricpropulsion installation embodiment two schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical solutions of the utility model are described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, for the utility model headrest of chair electricpropulsion installation embodiment one, comprise electric plating propulsion 1, the propeller 12 that this electric plating propulsion 1 comprises motor 11 and is connected with motor output shaft, have thread plate 121 at this propeller 12 internal fixtion, this thread plate 121 is connected with the output thread spindle 111 of motor 11; Also comprise the headrest frame 2 leaned on for mounting head, this headrest frame 2 comprises the pedestal 21 for fixing propeller 12, screw 122 is had to be coupling with the pedestal 21 on headrest frame 2 in the outside of this propeller 12, this pedestal 21 is for grooved frame is to ensure that described headrest frame 2 balances, easy motion, this headrest frame 2 is fixed with left axis of travel 22 and the right axis of travel 23 of symmetrical installation, in order to install what facilitate the left axis of travel of the present embodiment 22 and right axis of travel 23 to adopt is screw rod; Also comprise the fixed mount 3 being fixed on back by fixed head 34, this fixed mount 3 comprises the support plate 31 for fixing motor 11, this support plate 31, by axis hole 311 and axillare 13 pivot joint of being fixed on motor 11, this fixed mount 3 also comprises the left groove 32 of accommodating left axis of travel 22 and the right groove 33 of accommodating right axis of travel 23.So, under the state that motor starts, the rectilinear motion circular motion that motor 11 exports being become propeller 12 is coordinated by thread spindle 111 and thread plate 121, this propeller 12 drives headrest frame 2 moving linearly by the pedestal 21 be fixed on headrest frame 2, realization moves up and down, and also namely drives head rest to move up and down.By installing left axis of travel 22 and right axis of travel 23 coordinates with left groove 32, right groove 33, to ensure that headrest frame 2 balances steady movement.So, end user can be sitting on chair only needs to press the height that motor switch can be adjustable headrest of chair.
The present embodiment one, described headrest frame 2 is longitudinally curved, described left groove 32 and right groove 33 is all curved matches with headrest frame 2 arc.So, by headrest frame 2 traveling process, the different headrest frame 2 in position is also different from the angle of fixed mount 3, can also realize the minute movement before and after head rest, is also front and rear angles.
The present embodiment one, described headrest frame 2 upper end 25 is kink.This structure is mainly applicable to inside the present embodiment being installed on back, and to ensure the installing space of head rest, head rest is elevated from the central portion on back top.
Be illustrated in figure 4 the utility model headrest of chair electricpropulsion installation embodiment two, the upper end 25 of described headrest frame 2 is erection part.This structure is mainly applicable to the present embodiment to be installed on the rear back side of back.Ensure the installing space of head rest.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present utility model.
