Description

A kind of axle construction of seat switch

Technical field

This utility model relates to regulating switch for automobile seat field, particularly relates to the axle construction of a kind of seat switch.

Background technology

At present, the mode of the fixing employing axis hole matched in clearance between switch shift lever and the pedestal of automotive seat.Switch for adjusting seat is connected with switch shift lever, and human pilot, by using seat switch, drives switch shift lever to rotate, thus starting motor so that it is the position of seat or the inclination angle etc. of backrest are adjusted.But, on switch shift lever, the axle for carrying out shaft hole matching with pedestal leaves burr, and burr easily makes axle be stuck in the axle spacing hole of pedestal, not only can reduce the fluency that switch shift lever rotates, it is unfavorable for Consumer's Experience, also can reduce the service life of this part, affect product quality.

Utility model content

The purpose of this utility model is to provide the axle construction of a kind of seat switch, its simple in construction, cost of manufacture is relatively low, it is possible not only to improve the flexibility of revolution of switch shift lever, improve Consumer's Experience, the axis body on switch shift lever and the ruggedness of the axle spacing hole on the pedestal being mated can also be improved, increase the service life.

For achieving the above object, this utility model provides the axle construction of a kind of seat switch, including on the switch shift lever being arranged on seat, for forming the axis body of axis hole matched in clearance with the axle spacing hole of pedestal, described axis body includes the first side wall and the second sidewall, described the first side wall is using the axle center of the axis body arc surface as its axis, described second sidewall intersects with the mold parting surface of this axis body, it leaves the burr formed because of described mold parting surface, this second sidewall is make described burr outermost end along the radius of turn in axis body axle center less than the sidewall of the arc surface radius of the first side wall.

As further improvement of the utility model, described second sidewall is horizontal plane, and the beeline between described second sidewall and the axle center of axis body is less than the arc surface radius of described the first side wall.

Further improving as of the present utility model, described second sidewall is concave surface.

Further improving as of the present utility model, the distance between bottom and the axle center of axis body of described burr is equal to the beeline between the second sidewall and the axle center of axis body.

Beneficial effect

Compared with prior art, the axle construction of seat switch of the present utility model has the advantage that

1, axis body includes the first side wall and the second sidewall, the first side wall is using the axle center of the axis body arc surface as its axis, second sidewall leaves the burr of projection, burr outermost end along the radius of turn in axis body axle center less than the arc surface radius of the first side wall, this structure can effectively prevent the burr on axis body and the axle spacing hole contact internal walls on pedestal, its simple in construction, cost of manufacture is relatively low, it is possible not only to improve the flexibility of revolution of switch shift lever, improve Consumer's Experience, the ruggedness of the pedestal axle spacing hole that can also improve switch shift lever and be mated, thus increasing the service life；

2, the second sidewall is horizontal plane, and the beeline between the second sidewall and the axle center of axis body is less than the arc surface radius of the first side wall, and this kind of axis structure is prone to processing, and cost of manufacture is relatively low, and ensure that the mechanical stability of axis body；

3, the distance between bottom and the axle center of axis body of burr is equal to the beeline between the second sidewall and the axle center of axis body, burr head and the axle spacing hole inwall on pedestal can be made apart from maximum, thus allowing the second sidewall big as far as possible to the beeline in axis body axle center, to ensure the intensity of axis body, extend its service life further.

By description below and in conjunction with accompanying drawing, this utility model will become more fully apparent, and these accompanying drawings are used for explaining embodiment of the present utility model.

Detailed description of the invention

With reference now to accompanying drawing, embodiment of the present utility model is described.

Embodiment 1

Detailed description of the invention of the present utility model such as Fig. 1 is to shown in 2, a kind of axle construction of seat switch, including on the switch shift lever being arranged on seat, for forming the axis body 1 of axis hole matched in clearance with the axle spacing hole 3 of pedestal, axis body 1 includes the first side wall 4 and the second sidewall 5, and the first side wall 4 is using the axle center of axis body 1 arc surface as its axis；Second sidewall 5 intersects with the mold parting surface of this axis body 1, and it leaves the burr 2 formed because of mold parting surface, and this second sidewall 5 makes burr 2 outermost end along the radius of turn in axis body 1 axle center less than the arc surface radius of the first side wall 4.This structure can effectively prevent the contact internal walls of the burr 2 on axis body 1 and axle spacing hole 3, its simple in construction, cost of manufacture is relatively low, it is possible not only to improve the flexibility of revolution of switch shift lever, improve Consumer's Experience, the ruggedness of the axis body 1 on switch shift lever and the axle spacing hole 3 on pedestal can also be improved, thus increasing the service life.

In the present embodiment, the quantity of the second sidewall 5 is two；Between two the second sidewalls 5, the axle center along axis body 1 is arranged symmetrically with.

Second sidewall 5 is horizontal plane, and the beeline between the second sidewall 5 and the axle center of axis body 1 is less than the arc surface radius of the first side wall 4, and the structure of this kind of axis body 1 is prone to processing, and cost of manufacture is relatively low, and ensure that the mechanical stability of axis body 1.

Second sidewall 5 is vertical with mold parting surface, and mold parting surface is through the axle center of axis body 1, so that the bottom of burr 2 to the distance in axis body 1 axle center equal to the beeline of the second sidewall 5 to axis body 1 axle center, the head of burr 2 and axle spacing hole 3 inwall on pedestal can be made apart from maximum, thus allowing the second sidewall 5 big as far as possible to the beeline in axis body 1 axle center, to ensure the intensity of axis body 1, extend its service life further.

In above-described embodiment, the second sidewall 5 can also be concave surface, and burr 2 is positioned at the bottom of this concave surface.

Above in association with most preferred embodiment, this utility model is described, but this utility model is not limited to embodiment disclosed above, and should contain various carry out according to essence of the present utility model amendment, equivalent combinations.
