Description

Handrail hinge with hovering function

Technical Field

The utility model belongs to the technical field of the car handrail, a handrail hinge that has function of hovering is related to.

Background

The existing automobile handrails are various in types, but most of the automobile handrails are gear handrails, torsion spring structure turnover handrails and automatic locking structure handrails, and have the defects of high noise, inconvenience in taking parts and the like; the requirements of customers on the handrails are more and more, the handrails are required to hover at any angle in the movement range, and the rotating force is stable and has no abnormal sound in the movement process. And a plastic part and metal part interference fit structure is redesigned to meet the 3 functional requirements.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art and the actual situation, the utility model provides a handrail hinge with hovering function, which comprises an upper rotating arm of the hinge, a rotating shaft, a lower hinge support, a split washer, a shaft sleeve, a leaf spring and a screw, wherein two ends of the rotating shaft pass through side holes of the lower hinge support, the outer ends of support lugs of the lower hinge support are coated with lubricating grease, the upper hinge arm is connected with two ends of the rotating shaft, and the split washer is arranged on the rotating shaft at the inner side of the support lugs of the lower hinge support; the middle of the rotating shaft is sleeved with a shaft sleeve, the shaft sleeve is in interference fit with the rotating shaft, the plate spring comprises an annular sleeved part and a fastening part, the fastening part is two flat plates connected with two ends of the annular sleeved part, a through hole is formed in the upper flat plate, a threaded hole is formed in the lower flat plate, the plate spring is sleeved outside the shaft sleeve, and an M6 screw is arranged in a manner of being matched with the threaded hole; the middle position of the surface of the shaft sleeve is provided with a boss, and the plate spring is provided with a notch corresponding to the boss.

Preferably, two ends of the rotating shaft are riveted.

Preferably, the sleeve material is POM.

Preferably, the material of the rotating shaft is steel, and the surface is smooth.

Preferably, the plate spring material is 65 Mn.

Has the advantages that:

1. the armrest hinge has a hovering function at any angle in a movement range;

2. the rotating force value is stable, and the torque range is wide; 2.0-2.6 N.m;

3. no abnormal sound is produced during the exercise;

4. simple structure, convenient installation and low cost.

Fig. 2 is a schematic view of a usage state of the armrest hinge with hovering function according to an embodiment of the present invention.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses a handrail hinge with hovering function:

an armrest hinge structure:

1. assembling 1: the rotating shaft 3 penetrates through a side hole of the lower hinge support 2 and is provided with an open retainer ring 5;

2. assembling 2, coating lubricating grease on the outer ends of the lugs of the lower hinge support 2, and then loading the lubricating grease into the upper rotating arm 1 of the hinge;

3. riveting 1: riveting two ends of the rotating shaft 3;

4. assembling 3: a shaft sleeve 4 is arranged in the middle of the rotating shaft 3, then the plate spring 6 is pressed in, and then the plate spring 6 is locked by an M6 screw 7;

5. checking; the rotational torque of the armrest hinge was measured and recorded.

Secondly, the working process of the handrail hinge is as follows:

the shaft sleeve 4 is made of POM and has excellent wear resistance; the rotating shaft 3 is made of steel and has a smooth surface; the plate spring 6 is made of 65Mn, and has higher strength after heat treatment; the force value of the contact surface of the upper rotating arm 1 of the hinge and the lower support 2 of the hinge is very small and is ignored; the shaft sleeve 4 is clamped in the middle of the rotating shaft 3 to generate interference fit, then the plate spring 6 is pressed in the surface of the shaft sleeve 4, and a gap of the plate spring 6 and a boss on the surface of the shaft sleeve 4 are just embedded, so that the shaft sleeve is prevented from moving left and right and rotating with the plate spring; then locking a screw 7 on a threaded hole of the plate spring, and increasing the interference fit size of the shaft sleeve 4 and the rotating shaft 3 to enable the interaction force of the shaft sleeve 4 and the rotating shaft 3 to reach the technical requirement force value; the shaft sleeve 4 and the rotating shaft 3 rotate mutually to generate friction force which is larger than the gravity of a product acting on the upper rotating arm, and the handrail hinge has a hovering function.

The utility model uses the plastic part shaft sleeve 4 to eliminate abnormal sound and stabilize the rotation torque generated in the movement of the handrail hinge, and uses the plate spring 6 to control the rotation torque of the handrail hinge and has good fatigue resistance; simple structure, convenient assembly and low cost.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
