The technical scheme that its technical matters that solves the utility model adopts is as follows:
A kind of car seat headrest electric lifting mechanism, it comprises with cushion frame square tube bonded assembly anchor fitting, can drive Motorized lift device and actuator that headrest slides up and down; Described anchor fitting is a lifting fixed mount of captiveing joint with the cushion frame square tube; Described jacking system is one vertically to be located in the movable leading screw in the Fixed Nut, and this activity leading screw is connected with a lifting tressel, and these lifting tressel both sides respectively connect a lifting slip guide pillar, captives joint with headrest in this lifting slip guide pillar top; Described actuator is a synchronous reversible electric machine, or is one by motor-driven speed reduction gearing, by this driver drives activity leading screw rotation.
The utility model in use, only need press actuator button, rotate by driver drives activity leading screw, the rotation of movable leading screw in Fixed Nut makes it for vertical movement, the lifting tressel that drive is attached thereto moves, the headrest that is installed in lifting slip guide pillar on the lifting tressel and top thereof is also for vertical movement thereupon, realizes the height adjustment of headrest.
The beneficial effects of the utility model are:
1, can realize the height adjustment of resting the head on, operation and easy to use by pressing actuator button.
2, simple in structure, there is not complicated matching relationship, processing and easily manufactured.
Description of drawings
Fig. 1 is the structural representation of the utility model car seat headrest electric lifting mechanism
Fig. 2 is the A-A cutaway view of Fig. 1
Among the figure, 2. lifting slip guide pillars, 3. guide pin bushings, the 4. cushion frame square tubes of 1. resting the head on, 5. lifting fixed mounts, 6. Fixed Nuts, 7. movable leading screw 8. fixed slip bars 9. lifting tressels 10. cards 11. actuators 12. bearing pins 13. torsion springs
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Figure 1 shows that an embodiment of the utility model car seat headrest automatic hoisting mechanism, this electric lifting mechanism mainly comprises three parts: with cushion frame square tube 4 bonded assembly anchor fittings, can drive headrest 1 Motorized lift device that slides up and down and actuator 11.This anchor fitting is a lifting fixed mount 5 of captiveing joint with cushion frame square tube 4, is welded with guide pin bushing 3, Fixed Nut 6 and fixed slip bar 8 on lifting fixed mount 5, forms anchor fitting part of the present utility model.Guide pin bushing 3 and fixed slip bar 8 respectively have two, place the both sides of lifting fixed mount respectively.
Motorized lift device of the present utility model comprises that one vertically is located in the movable leading screw 7 in the Fixed Nut 6, this activity leading screw 7 is connected with a lifting tressel 9, each captive joint one lifting slip guide pillar 2 of these lifting tressel 9 both sides, captive joint with headrest 1 in these lifting slip guide pillar 2 tops, two guide pin bushings 3 are enclosed within respectively outside the lifting slip guide pillar 2.
Actuator 11 of the present utility model can be a synchronous reversible electric machine, or is shown in Figure 1 by motor-driven speed reduction gearing, and the gear output shaft of this speed reduction gearing links to each other with movable leading screw 7, by 7 rotations of actuator 11 driving activity leading screws.The button of actuator 11 can be arranged on the position of being convenient to press, and as the seat side, car door inner face etc. is located.Actuator 11 of the present utility model can be installed on the lifting tressel 9 as shown in Figure 1, and Fixed Nut 6 is welded on the lifting fixed mount 5; Also actuator 11 can be installed on the lifting fixed mount 5, and Fixed Nut 6 is fixedly mounted on the lifting tressel 9.
In order to ensure the headrest vertical lift, the utility model also is provided with lifting and guiding device, this lifting and guiding device is the fixed slip bar 8 that is vertically welded in lifting fixed mount 5 both sides, one end of this fixed slip bar 8 is connected with cushion frame square tube 4, the other end is located in the lifting tressel 9 corresponding holes, and lifting tressel 9 can be along fixed slip bar 8 vertical lifts.
In order to ensure lifting slip guide pillar 2 can with movable leading screw 7 synchronization liftings, the utility model is provided with lifting slip guide pillar gripping mechanism; For the ease of the dismounting of headrest, to be convenient for changing chair cover etc., the utility model also is provided with the headrest detachable apparatus.See also shown in Figure 2, on lifting tressel 9 both sides one bearing pin 12 is housed respectively, one torsion spring 13 is housed on this bearing pin 12, and the other end of this torsion spring 13 is connected with card 10, and the other end of card 10 is stuck in the circular groove of being opened on the lifting slip guide pillar 2 of headrest 1 lower end.
Working process of the present utility model is as follows: press the drive power supply button, give actuator 11 energized, reducer gear output shaft drive activity leading screw 7 rotations of actuator, because the Fixed Nut 6 that movable leading screw 7 is worn maintains static, make movable leading screw 7 for vertical movement, and drive the lifting tressel 9 that is attached thereto and make vertical lift along fixed slip bar 8.Because the card 10 that is installed on the bearing pin 12 on the lifting tressel 9 is clamped in the circular groove of being opened on the lifting slip guide pillar 2, make lifting slip guide pillar 2 for vertical movement, thereby make the headrest 1 that is installed in lifting slip guide pillar 2 tops can make height adjustment with lifting tressel 9.Change the direction of current of power supply, headrest is moved round about, thereby make headrest adjust to correct position.
When needs disassembled headrest 1 temporarily, only with hand pinched two cards 10 and moves to the centre, makes it to leave the circular groove on the lifting slip guide pillar 2, and card 10 no longer blocks lifting slip guide pillar 2, and the guide pillar 2 that then lifting can be slided is extracted out together with headrest 1.When reinstalling, only need to insert to next, spring 13 resets, and card 10 is stuck in the circular groove of lifting slip guide pillar 2 again, the descending operation that can rest the head on.
