Embodiment

To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with accompanying drawing It is described in detail on step ground.

Embodiment 1：The overall structure diagram of the present embodiment shown in reference picture 1.

A kind of automobile armrest position device for regulating rotary of the embodiment of the present invention, includes pedestal 1 and rotation is arranged at Movable disk 2, bent wheel 3 on pedestal 1, bent pawl 4.

At least one ratchet position 21 engaged with the bent end 41 of pawl 4 is provided with movable disk 2, in the present embodiment, to set Three continuous three ratchet positions 21 are put, realize the regulation of three-phase class, the handrail for interlocking movable disk 2 there are three angles optional Select.

There is the first ridge 31 on the circumference of song wheel 3, there is the second ridge 22 on the circumference of movable disk 2, with work The rotation of Moving plate 2, the second ridge 22 can promote the first ridge 31, bent wheel 3 is produced the rotation of certain angle.

In the present embodiment, the first ridge 31, the second ridge 22 are double wedge, and the surface between double wedge is relatively sliding It is dynamic.

The bent head end 42 of pawl 4 has a neck 43, and bent wheel 3 is additionally provided with the circumference on the opposite side of the first ridge 31 Latch 32, latch 32 can be sticked in neck 43.

Movable disk 2 has projection 23 in the provided circumferentially about of 22 happy side of the second ridge.

In the present embodiment, bent pawl 4 is preferably " L " shape.

When movable disk 2 rotates to a direction, the projection 23 in movable disk 2 is engaged with the bent end 41 of pawl 4, drive The bent end 41 of pawl 4 produces the rotation of certain angle, tilts the neck 43 of the bent head end 42 of pawl 4, makes the latch 32 and neck of bent wheel 3 43 depart from, and then when movable disk 2 rotates in the opposite direction, the bent end 41 of pawl 4 is fallen into ratchet position 21, make handrail that rotation may be selected Gyration, and continue direction rotation, the second ridge 22 and the first ridge 31 of bent wheel 3 for making movable disk 2 contact, and make song Wheel 3 produces the rotation of certain angle, slides into madial wall of the latch 32 of bent wheel 3 along bent pawl 4 and falls into neck 43.

And cause equipment to break down to prevent movable disk 2 from rotating excessively, arcuate movement groove is provided with movable disk 2 24, and the banking pin 11 being placed in arcuate movement groove 24 is provided with pedestal 1, banking pin 11 cooperates with loose slot 24, makes Second ridge 22, which turns to, promotes the first ridge 31 latch 32 is fallen into neck 43, or projection 23 is turned to promotion song The end 41 of pawl 4 makes latch 32 depart from neck 43.

More optimizedly, the first spring 33 is provided between bent wheel 3 and pedestal 1, makes the elastic engaging of latch 32 in neck 43, Second spring 44 is provided between bent pawl 4 and pedestal 1, makes flexible stress between neck 43 and latch 32.

In the present embodiment, the first spring 33, second spring 44 are torsion spring.

Under the effect of the first spring 33, make latch 32 after neck 43 is departed from the side wall of the head end 42 of bent pawl 4.

A support pin 12 is additionally provided with pedestal 1, the pin is used to provide bullet to first spring, second spring Property support.

Embodiment 2：Structural representation shown in reference picture 2, in the present embodiment, the first ridge 31 be double wedge and the Two ridges 22 are convex globoidal, and convex globoidal makes the double wedge of bent wheel 3 drive rotation one in the lump in the rotation process with movable disk 2 Determine angle, the side walls of head end 42 of the latch 32 along bent pawl 4 is fallen into the neck 43 of bent pawl 4, handrail is freely up and down revolved Turn.

Other structures are consistent with being stated in embodiment 1, and the present embodiment does not do duplicate explanation herein.

Embodiment 3：Structural representation shown in reference picture 3, in the present embodiment, the first ridge 31 be convex globoidal and Second ridge 22 is double wedge, and double wedge makes the convex globoidal of bent wheel 3 drive rotation one in the lump in the rotation process with movable disk 2 Determine angle, the side walls of head end 42 of the latch 32 along bent pawl 4 is fallen into the neck 43 of bent pawl 4, handrail is freely up and down revolved Turn.

Embodiment 4：Structural representation shown in reference picture 4, in the present embodiment, the first ridge 31, the second ridge 22 be convex globoidal, and convex globoidal makes the convex globoidal of bent wheel 3 drive in the lump and turned an angle in the rotation process with movable disk 2, The side walls of head end 42 of the latch 32 along bent pawl 4 is fallen into the neck 43 of bent pawl 4, handrail is freely up and down rotated.
