A kind of electric steering column height adjustment seat
Technical field
The utility model relates to electric power steering system of automobile, and in particular to a kind of electric steering column height adjustment
Seat.
Background technique
With the development of vehicle automotive engineering, steering wheel height adjustment has become standard configuration, different drivers on passenger car
When driving this automobile, since height, weight, driving habit are different, the height of steering wheel can be adjusted, meeting when adjusting
Then steering wheel is adjusted to a suitable position in set lever again, has guaranteed that steering wheel is able to maintain by release handle
On the position of the adjustment.The process is realized by the height adjustment mechanism on electric steering column.
Then common height adjustment mechanism steering wheel from the upper (lower) limit adjust under (on) limit when lock respectively
When (release) handle, handle power difference is excessive, and for extreme differences about in 40N or so, causing may when steering wheel is in limit inferior
Occur keep do not live the case where, seriously affected the quality of vehicle, reduced the comfort of driver, threatened vehicle and
The safety of driver and passenger.
Utility model content
In order to promote the quality of steering system, a kind of electric steering column height adjustment seat of the utility model should
The difference of high-low limit handle power when height adjustment seat can reduce steering wheel height adjustment promotes driver's set lever
Comfort property.
A kind of electric steering column height adjustment seat, including bottom plate, are provided with to be parallel to each other on the bottom plate and set
The first side plate and the second side plate set, the bottom plate, the first side plate and second side board group are at U-shaped structure, in first side
Bar shaped sliding slot, the length direction court of the bar shaped sliding slot are offered on the first end end of plate and the first end end of the second side plate
To the bottom plate, the first end of first side plate and the second side plate is respectively positioned at the outer ledge of the bottom plate, and feature exists
In: bottom plate connection integrated with first side plate and the second side plate is opened in the transition position of the bottom plate and the second side plate
Equipped with U-shaped notch, the first side side of the U-shaped notch is located on the bottom plate, and second side side of the U-shaped notch is located at
On second side plate, second side side of the U-shaped notch is located at the underface of the bar shaped sliding slot.
Further are as follows: the bar shaped sliding slot on second side plate is located at the middle position of U-shaped notch second side side
Surface.Make in this way, the first side plate and the second side plate are when the position aperture direction of bar shaped sliding slot is close to each other, second side
The deformation effect of plate is more preferable.
Further are as follows: the length direction of the bar shaped sliding slot on second side plate is vertical with U-shaped notch second side side;
The adjustment seat of this structure, the height being more convenient for through adjustment direction disk above and below bar shaped sliding slot.
Further are as follows: the transition junction of first side plate and the second side plate and the bottom plate is arc, convenient for adding
Work, stress performance are good.
Further are as follows: the width of the first side plate first end end is greater than the width of the first side plate second end end
Degree, the width of the second side plate first end end are greater than the width of the second side plate second end end.
Further are as follows: the first end end of second side plate is denoted as movable part, by the second end of second side plate
End is denoted as fixed part, and the length of U-shaped notch second side side is identical as the length of the movable part, so that second
The deformation of side plate is in the junction of movable part and fixed part, and since fixed part width is narrow, movable part and fixed part junction become
Shape effect is good, so that handle power is small, convenient for operation.
The utility model has the beneficial effects that being clamped in limit inferior o'clock by the deformation of the second side plate and the cooperation of the first side plate
The transition position of the height regulating mechanism of steering wheel, bottom plate and the second side plate is arranged U-shaped notch, by original bottom plate and the at deformation
The transition position of two side plates is converted to second side plate itself close to the position of U-shaped indentations bottom;Due to limes superiors and limit inferior height
The deformation point of adjustment mainly on the second side plate, so that the handle power difference in limes superiors and limit inferior adjustment is smaller, is convenient for adjusting
It is whole, improve comfort.

Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.It should be noted that in the utility model truth example
The positional terms such as left, center, right, upper and lower, be only each other relative concept or be with the normal operating condition of product refer to, and
It should not be regarded as restrictive.
A kind of electric steering column height adjustment seat is set on the bottom plate 43 as shown in Figure 1, including bottom plate 43
It is equipped with the first side plate 41 and the second side plate 42 arranged in parallel, 42 groups of the bottom plate 43, the first side plate 41 and the second side plate
At U-shaped structure, item is offered on the first end end of first side plate 41 and the first end end of the second side plate 42
Shape sliding slot 45, the length direction of the bar shaped sliding slot 45 is towards the bottom plate 43, and the of first side plate 41 and the second side plate 42
One end is respectively positioned at the outer ledge of the bottom plate 43, and the bottom plate 43 is integrated with first side plate 41 and the second side plate 42
Connection, offers U-shaped notch 44, the first side side of the U-shaped notch 44 in the transition position of the bottom plate 43 and the second side plate 42
Side 441 is located on the bottom plate 43, and second side side 442 of the U-shaped notch 44 is located on second side plate 42, the U
Second side side 442 of type notch 44 is located at the underface of the bar shaped sliding slot 45;
Wherein, specifically, the bar shaped sliding slot 45 on second side plate 42 is located at U-shaped 44 second side side of notch
The surface in 442 middle position, the length direction and the U-shaped notch 44 second of the bar shaped sliding slot 45 on second side plate 42
Side side 442 is vertical, and the transition junction of first side plate 41 and the second side plate 42 and the bottom plate 43 is arc;It is described
The width of first side plate, 41 first end end is greater than the width of the 41 second end end of the first side plate, second side plate 42 the
