detailed description

Hereinafter, firstly, a steering wheel is described with reference to FIGS. 1 to 4, which has a steering wheel damping system according to the first embodiment of the present invention, wherein FIG. 1 is a half view of the steering wheel, and FIG. 2 is along FIG. 3 is a partial enlarged view of FIG. 2 and FIG. 4 is a partial enlarged view of FIG. 3.

The steering wheel has a steering wheel body 1 and an airbag module 2 provided in the center of the steering wheel body. The steering wheel body 1 may include a metal skeleton 14 and a foamed base 15, and the foamed base wraps the metal skeleton 14. The steering wheel body 1 may have a rim, and the driver's hand may be held on the rim. Accessories and operating elements can be provided on the steering wheel body 1. The airbag module 2 is configured to be activated in an emergency state of the vehicle, such as when the vehicle crashes or rolls over, to pop out the inflated airbag 4 to provide safety protection for the driver. The airbag module 2 includes an airbag door cover 3 and a housing part 5. The airbag door cover and the housing part constitute a housing of the airbag module, and the housing has an accommodation chamber for accommodating the folded airbag 4 . The airbag module 2 may include an inflator 6, which may be configured as a pyrotechnic gas generator, for example. The inflator 6 may be installed in the center of the housing part 5. The airbag module 2 may include a retaining ring 9 for retaining the airbag 4. Advantageously, the inflator 6 and the retaining ring 9 are fixed to the housing part 5 by a common fastening device 8. The fastening device may be, for example, a bolt connection device, which includes a bolt and a nut. The airbag door cover 3 may be configured to be mounted to the steering wheel main body 1 and decoupled from the housing part 5. To this end, the airbag door cover 3 may have a peripheral edge and a fixing element 13 protruding from the peripheral edge, the fixing element being configured to be inserted into the fixing hole 16 of the foam base 15 of the steering wheel main body. Advantageously, the fixing element 13 may have a mushroom head configured to form-lockingly connect the fixing element 13 with the fixing hole 16, wherein the fixing hole 16 may have a mushroom head matching Undercut. The airbag door cover 3 and the housing part 5 may have

peripheral walls

10 and 11, respectively. The peripheral wall 11 of the airbag door cover 3 overlaps the peripheral wall 10 of the housing part 5 and is positioned in the axial direction of the airbag module 2. The upper can move relative to each other. In order to limit the separation stroke of the airbag door cover 3 and the housing part 5 when the airbag module 2 is activated to improve safety, the peripheral wall 10 of the housing part 5 may have a hook 12, and the peripheral wall of the airbag door cover may have a restriction Hole 18, the hook extends into the restriction hole. The restriction hole 18 may be configured as an elongated hole extending in the axial direction, for example.

The mass may include a housing part 5 of the airbag module 2 and a part supported by the housing part 5, such as an inflator 6, a retaining ring 9, a fastening device 8 and Folding airbag 4 and so on. The airbag door cover 3 is decoupled from the housing part 5 and does not belong to the mass block, so it does not participate in the vibration damping function of the steering wheel vibration damping system. Thereby, when the airbag door cover is assembled on the steering wheel body, the predetermined outline size relative to the steering wheel body can be permanently maintained, without the defect that the airbag module collapses relative to the steering wheel body as may occur in the prior art. . In addition, during the use of the vehicle, the airbag door cover 3 may be frequently pressed. In the known steering wheel with a steering wheel damping system, pressing the airbag door cover may adversely affect the elastic element of the steering wheel damping system and thereby affect the damping function.

Each damping assembly may include at least one elastic element. The damping components can act on a common mass in parallel with each other. An exemplary vibration damping assembly is shown in FIGS. 1 to 4, which includes a pin 20 and a first elastic body 21. The pin 20 may be a metal pin. The pin 20 has a first end section and a second end section, the first end section is vibrationally coupled to the housing part 5, and the second end section is vibrationally coupled to the steering wheel body 1. The pins may have tapered or hemispherical ends, for example.

The first elastic body 21 is provided in the area of the first end section and wraps the first end section. The first elastic body 21 may be formed integrally with the pin 20 through an injection molding or vulcanization process, for example. The housing part 5 may have a mounting hole for receiving the pin 20. The mounting hole may be, for example, a blind hole or a through hole 7, preferably the through hole is a counter hole. The pin 20 may have a head 33 in the first end section, and the combined body of the pin 20 and the first elastic body 21 or the combined head of the vibration damping component rests on the back of the through hole 7 On the first side of the second end section, it is preferably received in the sinker of the counterbore. The combined body or the combined rod portion of the vibration damping assembly is matched with the through hole 7. Preferably, the diameter of the head 33 may be larger than the diameter of the through hole 7. On the first side of the through hole 7, the combined head can be fixed by a pressure plate 28 fixed on the housing part 5. The pressure plate 28 can compress the head of the first elastic body 21 applied to the pin 20 The surface part on the section 33. Advantageously, the pressure plate 28 can be fixed to the housing part 5 by a retaining ring 9. The pressing plate 28 may additionally have a hook, whereby the pressing plate can be hooked on the housing part 5 to further ensure the fixing of the pressing plate 28 on the housing part 5.

In order for the pin 20 to vibrately couple with the steering wheel body 1 in the second end section, the pin 20 may be connected to the steering wheel body 1 or pressed against the steering wheel body 1 so as to transmit the vibration of the steering wheel body 1 to the pin 20 . As shown in Figures 2 to 4, the second end section may have a neck 24 configured to receive a fixing wire 17 provided in the steering wheel body 1, so that the pin 20 can The fixing wire 17 is fixed to the steering wheel body 1. During installation, the pin 20 can be squeezed toward the steering wheel body 1 so that the fixing wire 17 slides into the neck 24. The steering wheel damping system may include an elastic member 23 that has higher rigidity than the first elastic body 21 and can be fixed in the steering wheel main body 1, and the pin 20 can be compressed with its end facing away from the housing member 5. On the elastic member 23, the pin 20 is pressed against the steering wheel main body 1 as a result.

The steering wheel vibration damping system may include a pressing device 30 for a vehicle horn, the pressing device being partially or completely decoupled from the mass. The pressing device 30 may include a pressing upper piece 31 and a pressing lower piece 32, and a pressing spring (not shown in the figure) that separates the pressing upper piece and the pressing lower piece from each other. Advantageously, the upper pressing piece, the pressing spring and the lower pressing piece can be constructed as a single structural unit, which can be mounted to the steering wheel main body 1. Typically, the pressing spring may be a helical compression spring or a spring-type spring. The upper click piece 31 and the lower click piece 32 may have contact points, respectively. When the airbag door cover 3 is pressed, the upper pressing piece 31 can overcome the pressing spring and move toward the lower pressing piece 32, so that the contacts of the upper pressing piece and the lower pressing piece are in contact and conduction, so that the vehicle horn can sound. . When the pressure on the airbag door cover 3 is released, the upper pressing piece 31 is reset under the return force of the pressing spring, the contacts of the pressing upper piece and the lower pressing piece are separated from each other, and the vehicle horn stops sounding. Since the pressing device is decoupled from the steering wheel vibration reduction system, the pressing function and the vibration reduction function do not affect each other, so it is beneficial to maintain the vibration reduction function of the steering wheel vibration reduction system and the pressing function of the pressing sound device for a long time.
