Description

Locking structure of armrest in automobile rear seat

Technical Field

The utility model belongs to the technical field of automobile parts, and particularly relates to a locking structure of an armrest in an automobile rear seat.

Background

At present, locking systems of rear-row armrests of automotive interiors are diversified, and a gear-rack transmission system and a stay wire linkage system are used. The gear rack system is difficult to control running noise and has high requirements on the size of the gear rack; the wire linkage system is advantageous for space arrangement, but has great difficulty in noise control, and redundant wire length and noise design of the end connector are all the current difficulties, thus bringing extra cost. Therefore, there is a need for a locking structure for armrests in a rear seat of an automobile that reduces the size requirements of the parts and meets the noise requirements of the product.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, provides a locking structure of an armrest in an automobile rear seat, which has reasonable design and compact structure and meets the requirement of cost optimization, and solves the problem that the dimensional matching precision of the original gear rack structure is higher; and the redundant stay wire of the stay wire linkage structure is long.

The utility model solves the technical problems by adopting the following technical scheme:

a locking structure for an armrest in a rear seat of an automobile, comprising: the hand button comprises a hand button 1, a hand button frame 2, a front end connecting rod 3, a middle connecting rod 4, a rear end connecting rod 5, a middle sleeve 6, an unlocking sleeve 7, an unlocking spring 8, a locking shaft 9, a handrail framework 10, a handrail support 11, a spline shaft 12, a reed 13, a screw 14 and a rubber spring 15. The rotation shaft on the handle 1 is coaxially matched with the hole on the handle frame 2 and can rotate around the center line of the rotation shaft (as shown in an installation schematic diagram in fig. 4A), the handle frame 2 is connected with the armrest framework 10 through 2 screws 14, the front end connecting rod 3 is matched with the handle 1, the front end connecting rod 3 is matched with the middle connecting rod 4, the middle connecting rod 4 is matched with the rear end connecting rod 5 and the rear end connecting rod 5 is matched with the middle sleeve 6 through shaft holes, and the fixing and rotating functions are realized (as shown in fig. 3); the two rubber springs 15 are respectively fixed between the buckle 1 and the buckle frame 2 and between the intermediate connecting rod 4 and the armrest framework 10 (as shown in fig. 3), the buckle 1 is reset after being unlocked by being matched with the unlocking springs 8, the intermediate sleeve 6 is coaxially matched with the unlocking sleeve 7, two arc holes on the intermediate sleeve 6 are respectively matched with cylindrical bosses on the two unlocking sleeves 7 (as shown in an assembly relation diagram in fig. 8), the unlocking springs 8 are coaxially matched with the intermediate sleeve 6, two ends of the unlocking springs 8 are respectively fixedly connected with the two unlocking sleeves 7, the two unlocking sleeves 7 are connected with the two locking shafts 9 in a clamping mode, and the locking shafts 9 are matched with the armrest framework 10 through shaft holes; the spline shaft 12 is matched with the armrest framework 10 in a coaxial way, the spline shaft 12 is preassembled with a spline groove on the armrest support 11, and the reed 13 is connected with a circular groove B (shown in figure 12) on the spline shaft 12 in a clamping way (shown in figure 5); the middle sleeve 6 and the unlocking sleeve 7 are respectively formed by integral injection molding.

The motion process of the locking structure is as follows: when the armrest needs to be unlocked, the rotating motion of the armrest is changed into movement by the structure to drive the front end connecting rod 3, the middle connecting rod 4 and the rear end connecting rod 5 to move together; the movement of the rear connecting rod 5 is converted into the rotation of the middle sleeve 6, and the middle sleeve 6 converts the rotation into the movement through the inclined plane on the structure of the middle sleeve, so that the unlocking sleeve 7 and the locking shaft 9 move together into the handrail, and the unlocking sleeve is separated from the hole of the handrail bracket 11, and the unlocking of the handrail is realized. When the handrail needs to be locked, the whole locking structure can have the opposite movement trend under the action of the spring force of the rubber spring 15 and the unlocking spring 8, and when the locking shaft 9 performs the hole area of the handrail support 11, the locking shaft can automatically rebound into the hole to realize the locking of the handrail.

The utility model has the advantages and positive effects that:

the utility model effectively reduces the arrangement complexity of the armrests, effectively reduces the production and manufacturing cost and improves the quality qualification rate of products. Meanwhile, reference and rational choices are provided for subsequent product development.
