First catch point portion 211 is rotated to the direction far from main turntable 24 in point portion 211 so that interconnecting piece is to far from main turntable 24
Direction rotate.
The pivot end of outer tooth plate 21 is provided with the second catch point portion 212, the second catch point portion 212 be used for main turntable 24 against with
Make main turntable 24 that pivot end be pushed to rotate to the direction far from main turntable 24.Wherein, second gear is arranged in the pivot end of outer tooth plate 21
Point portion 212, when main turntable 24 rotates, when encountering the second catch point portion 212, main turntable 24 pushes the second catch point portion 212 to make second
Catch point portion 212 is rotated to the direction far from main turntable 24 so that articulated section is rotated to the direction far from main turntable 24.
As shown in figure 11, be provided on main turntable 24 dial point portion 242, dial point portion 242 for the first catch point portion 211 or
Second catch point portion 212 against and push the rotation of outer tooth plate 21.The first groove 51 is provided on transmission shaft 5, the first groove 51 is used for
Clamping circlip 4 is simultaneously connect with rotatable parts.It is connected with axle sleeve 11 on rotatable parts, the second groove 111, axis are provided on axle sleeve 11
Set 11 is arranged on the outer peripheral surface of transmission shaft 5, and the first groove 51 is corresponding with the second groove 111, and it is recessed that circlip 4 is connected in first simultaneously
It is moved axially in slot 51 and the second groove 111 with limiting axle sleeve 11 relative to transmission shaft 5.Wherein, circlip 4 is caught in first simultaneously
In groove 51 and the second groove 111, to limit the axial movement between axle sleeve 11 and transmission shaft 5, this set, structure is simple,
It is easy to install.
As shown in Figure 10, the outside of inner panel 26 is provided with stiffening plate 27, and escape groove 271 is provided in stiffening plate 27, evacuation
Slot 271 is corresponding with guide groove 261, and escape groove 271 is for avoiding guide rod 25, and stiffening plate 27 is for reinforcing inner panel 26.Wherein, by
It is all connect with inner panel 26 in outer tooth plate 21 and main turntable 24, therefore the service life of the intensity of inner panel 26 and entire angular adjustment assembly ceases
Manner of breathing closes, therefore is reinforced in the outside of outside plate 22 setting stiffening plate 27 with the intensity to inner panel 26.
The present invention also provides a kind of automobile seat arm, which includes angular adjustment machine as above
Structure.
In the present embodiment, being understood in conjunction with Fig. 5 to Fig. 9, the shape for the elastic slice 23 connecting with outer tooth plate 21 is Ω shape,
Referred to as Ω spring, one end of Ω spring are connect with the connecting pin on outer tooth plate 21, and the other end is connect with inner panel 26.When automotive seat is helped
When hand 1 is lifted up, main turntable 24 rotates counterclockwise, and the guide rod 25 on main turntable 24 is in the guide groove 261 on inner panel 26
It slides counterclockwise, the ratchet 241 on main turntable 24 slides relative to the outside wall surface of outer tooth plate 21, when on main turntable 24
When outer wall face contact of the last one ratchet 241 no longer with outer tooth plate 21, point portion 242 and the first catch point portion are dialled on main turntable 24
211 collide, and under the action of dialling the external force that point portion 242 applies the first catch point portion 211, the interconnecting piece of outer tooth plate 21 is around pivot joint
Portion rotates clockwise.Ω spring is rotated counterclockwise with the rotation of outer tooth plate 21 in this process, as shown in fig. 6, working as outer tooth plate
The both ends of 21 rotation center and Ω spring on the same line when, the direction of the power on Ω spring changes, so that outer tooth plate 21
Moment, which is quickly rotated clockwise to, no longer to rotate.At this point, outer tooth plate 21 is completely disengaged with main turntable 24, as shown in fig. 7, angle adjustor
Assembly 2 is in idle stroke state.When guide rod 25 is moved to the end of guide groove 261, as shown in figure 8, main turntable 24 stops turning
Dynamic, guide rod 25 is in stop bit position, and automobile seat arm 1 is in highest point.
When automobile seat arm 1 is rotated down from highest point, main turntable 24 is rotated clockwise, and dials point portion when rotating to
242 collide with the second catch point portion 212, under the action of dialling the external force that point portion 242 applies the second catch point portion 212, outer tooth plate 21
Articulated section can be rotated counterclockwise around articulated section.In this process, Ω spring can be clockwise with the rotation of outer tooth plate 21
Rotation, when the both ends of Ω spring again with the rotation center of outer tooth plate 21 on the same line when, the direction moment of the power on Ω spring
Change so that 21 moment of outer tooth plate quickly counterclockwise rotate and engaged with main turntable 24, when outer tooth plate 21 go to it is motionless
When, as shown in figure 9, angle adjustor assembly 2 replys reset condition.
It should be noted that in angle adjustor motion process, when unclamping automobile seat arm 1 to realize, angle adjustor is no longer
This effect is moved, pretightning force directly or indirectly need to be applied to transmission shaft 5.It in the present embodiment, is on the one hand by passing
The end of moving axis 5 increases corrugated gasket 28 to generate frictional force, when not applying external force on transmission shaft 5, in corrugated gasket 28 and wave
Under the frictional force effect that the face of the other parts at 28 both ends of shape gasket generates, transmission shaft 5 no longer rotates；On the other hand be by
Increase plastic part on the periphery of guide rod 25, so that producing when guide rod 25 slides in guide groove 261 with the edge of guide groove 261
Raw frictional force, and increase at the both ends of escape groove 271 with the amount of interference of guide rod 25 and pretightning force is provided.
Certainly, angle adjusting mechanism provided by the invention is not limited to be applied in automobile seat arm, this angular adjustment
Mechanism can be applied to the place that leg support, desktop etc. unidirectionally adjust angle.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these change and
