Fig. 1 schematically illustrates a steering wheel assembly according to an embodiment of the present invention. A steering wheel assembly according to an embodiment of the present invention is described below with reference to fig. 1.
As shown in fig. 1, a steering wheel assembly 1 according to the present invention includes a steering wheel unit 10 (only part of which is schematically shown) and a steering column 20 mounted together, and the steering wheel unit 10 includes a steering wheel skeleton 100 and an airbag (not shown) mounted on the steering wheel skeleton 100. Further, the steering wheel unit 10 according to the present invention further includes a locking device 200 provided on the steering wheel frame 100, the locking device 200 being used to lock the steering column 20 to the steering wheel frame 100 in the first direction D, which will be described in detail below.
It should be noted that, although not shown, the steering wheel unit 10 of the present invention includes an airbag that has been mounted on the steering wheel frame 100, that is, one of the technical problems that the present invention aims to solve is the attachment and detachment of the steering wheel unit to and from the steering column in the case where the airbag has been mounted on the steering wheel frame of the steering wheel unit.
Also, the term "locking in a first direction" herein refers to preventing, for example, relative movement of two members in a first direction. Specifically, the locking device 200 in the present invention locks the steering column 20 to the steering wheel frame 100 in the first direction D, meaning that the locking device 200 is capable of preventing relative movement of the steering column 20 with respect to the steering wheel frame 100 in the first direction D (in the orientation shown in fig. 1, the locking device 200 is used to prevent downward movement of the steering column 20, or it can also be understood that the locking device 200 is used to prevent upward movement of the steering wheel frame 100), so as to prevent the steering column 20 from being disengaged from the steering wheel frame 100.
Fig. 2 schematically illustrates a locking device 200 in a steering wheel assembly according to an embodiment of the invention. The locking device 200 in the steering wheel unit according to the present invention is described in detail below with reference to fig. 2.
As shown in fig. 2, the locking device 200 includes a first protruding portion 201 and a second protruding portion 202, the first protruding portion 201 and the second protruding portion 202 protruding from a first side 100B of the steering wheel skeleton 100 (i.e., a lower side of the steering wheel skeleton 100 in fig. 1), and the airbag is provided on a second side 100A of the steering wheel skeleton 100 (i.e., an upper side of the steering wheel skeleton 100 in fig. 1) opposite to the first side 100B.
Furthermore, in the embodiment shown in fig. 2, the locking device 200 further comprises a mounting pin 203, a bolt 204 and a frame structure 206. These components of the locking device 200 are described in detail below.
As shown in fig. 2, in the locking device 200, the ends of the first and second protrusions 201 and 202 (i.e., the upper ends in fig. 2) are each configured to have a frame structure 206, it is to be noted that the frame structures 206 of the first and second protrusions 201 and 202 may be formed integrally with the remaining portions thereof, respectively (i.e., the end of the first protrusion is formed integrally with one frame structure and the end of the second protrusion is formed integrally with the other frame structure), or the frame structures 206 of the first and second protrusions 201 and 202 may be formed as separate two portions and connected together via, for example, welding (i.e., the first protrusion is formed as two separate members with one frame structure and connected together by welding, and the second protrusion is formed as two separate members with the other frame structure and connected together by welding). As shown in connection with fig. 1, when mounted on the steering wheel frame 100, two frame structures 206 are positioned on the second side 100A of the steering wheel frame 100, and the other ends of both the first and second protrusions 201, 202 opposite the frame structures 206 pass through holes in the steering wheel frame 100 and extend beyond the first side 100B of the steering wheel frame 100.
In one example, the frame structure 206 is embodied as a U-shaped frame including openings, and the two frame structures 206 may be disposed identically and positioned such that the two openings are opposite one another. One frame structure 206 is positioned laterally offset a distance relative to the other frame structure 206, so that at the opening, one side of one frame structure 206 is offset from one side of the other frame structure 206 and has overlapping portions that overlap each other, through which the mounting pin 203 passes, such that one or both of the first and second protrusions 201, 202 can be rotated about the rotational axis of the mounting pin 203 to change the distance therebetween. It will be appreciated that the above example has the feature of securing two protrusions using fewer parts. Of course, the locking device of the present invention is not limited to the above example, for example, the frame structures are not limited to being identical to each other but may be provided to be different from each other, and one frame structure may overlap the other frame structure on both outer sides thereof, and for example, the frame structure may be omitted.
As shown in fig. 2, in order to actuate the first protrusion 201 and/or the second protrusion 202, a bolt 204 is provided, and accordingly, at least one of the first protrusion 201 and the second protrusion 202 is provided with a screw actuation hole, and the stud 204 is positioned to pass through the screw actuation hole, and the first protrusion 201 and/or the second protrusion 202 provided with the screw actuation hole is driven to pivot about the rotation axis (i.e., the above-described first axis) of the mounting pin 203 when the stud 204 is rotated.
It will be appreciated that the stud 204 may be provided with a fixed portion which restricts movement of the stud 204 in its axial direction but is only capable of rotational movement, in which case the first projection 201 and/or the second projection 202 move in the axial direction of the stud 204 via a threaded engagement between the threaded actuation bore and the stud 204 as the stud 204 is rotated. For example, the first protruding portion 201 and the second protruding portion 202 are provided with screw-thread actuating holes having opposite screw directions, i.e., the first protruding portion 201 is provided with a first screw-thread actuating hole that mates with the first screw-thread actuating section of the stud 203, the second protruding portion 202 is provided with a second screw-thread actuating hole that mates with the second screw-thread actuating section of the stud 203, and the first screw-thread actuating hole and the second screw-thread actuating hole are configured to have screw threads having opposite screw directions, so that, when the stud 203 is rotated, the first protruding portion 201 and the second protruding portion 202 are rotated in opposite directions about the rotation axis of the mounting pin 203; it can be appreciated that this example has a structure that enables the distance between the first protruding portion and the second protruding portion to be quickly changed to efficiently accomplish the attachment and detachment between the steering wheel unit 10 and the steering column. For another example, only one of the first protrusion 201 and the second protrusion 202 is provided with a screw actuation hole, and when the stud 203 is rotated, the protrusion provided with the screw actuation hole is rotatable about the rotation axis of the mounting pin 203 in a direction away from/toward the other protrusion; in this case, the other protruding portion may be provided with a through hole through which the stud 204 passes or be of a solid structure. Of course, this is merely an example, and the locking device of the present invention is not limited thereto, and for example, the stud 203 may be provided so as to be movable in the axial direction thereof while rotating, in which case the stud 203 may be movable in the axial direction thereof together with one projection.
As an alternative embodiment of the present invention, as shown in fig. 1, a mounting seat 300 fixed with the steering wheel frame 100 is further provided on the second side surface 100A of the steering wheel frame 100, and a mounting pin 203 pivotally fixes the first and second protrusions 201 and 202 passing through the through holes of the steering wheel frame 100 to the steering wheel frame 100 through mounting holes in the mounting seat 300. For example, both ends of the mounting pin 203 are fixed to the mount 300 via two nuts. For another example, the mounting pin 203 may be integrally formed with one nut as a nut end, the other end being fixed to the mounting base 300 via the nut, and the other end may be provided with an internal thread or an external thread, and accordingly, the nut engaged therewith may be provided with an external thread or an internal thread.
Thus, in the steering wheel unit and steering wheel assembly of the present invention, one or both of the first and second protrusions are pivotable about the first axis relative to the steering wheel skeleton such that the distance therebetween changes from a first distance to a second distance, and the second distance is different from the first distance. In one example, as in the steering wheel assembly 1 shown in fig. 3, the second distance is greater than the first distance, at which the first and second protrusions 201, 202 are interference fit with the threaded section of the steering column 20 at the inner side of the steering column 20 at the respective threaded section. In another example, as in the steering wheel assembly 1' shown in fig. 4, the second distance is less than the first distance, at which the first and second protrusions 201, 202 are interference fit with the threaded section of the steering column 20 at the outer side of the steering column 20 at the respective threaded section.
Thus, in the steering wheel unit and the steering wheel system of the present invention, in the case where the airbag has been mounted on the steering wheel skeleton, the steering column can still be mounted and dismounted in a simple and convenient manner.
As an alternative embodiment of the present invention, for the steering wheel assembly shown in fig. 3, an elastic member 207 is further provided in the frame structure 206, the elastic member 207 being located at the top of the mounting pin 203 and being in a compressed state, and thus, the elastic member 207 is configured to apply an elastic force such that the distance between the first protruding portion 201 and the second protruding portion 202 is reduced. It can be appreciated that the resilient member 207 facilitates the first and second protrusions 201, 202 to maintain a second distance to ensure that the first and second protrusions 201, 202 are interference fit with the threaded section of the steering column 20 at the outer side of the steering column 20 at the respective threaded section.
As an alternative embodiment of the invention, the first and second protrusions are further provided with a profiled surface which is adapted to the shape of the steering column and is provided with a threaded section, typically the steering column is provided in a cylindrical shape, whereby the profiled surfaces of both the first and second protrusions are provided in an arc shape.
As an alternative embodiment of the invention, the threaded sections of both the first and second protrusions are provided with unidirectional threads. It will be appreciated that this facilitates locking the steering column 20 to the steering wheel armature 100 in the first direction D.
As described above, although the exemplary embodiments of the present invention have been described in the specification with reference to the accompanying drawings, the present invention is not limited to the above-described specific embodiments, and the scope of the present invention should be defined by the claims and their equivalents.
