A steering wheel assembly according to an embodiment of the present invention is described below with reference to fig. 1 and 2.
As shown in fig. 1, a steering wheel assembly 1 according to the present invention includes a steering wheel unit 10 (only some parts of which are schematically shown) and a steering column 20 mounted together, and the steering wheel unit 10 includes a steering wheel frame 110, the steering wheel frame 110 includes a through hole 1101, the steering wheel frame 110 further includes a locking device 120 disposed near the through hole 1101 on the steering wheel frame 110, the locking device 120 being used to lock the steering column 20, which passes through the through hole 1101, to the steering wheel unit 10 in a 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 further includes an airbag mounted on the steering wheel frame 10, and the locking device 120 is provided on the same side of the steering wheel frame 110 (the same side is shown as the upper surface of the steering wheel frame 10 in fig. 1) as the airbag, that is, the technical problem that the present invention is intended to solve is the mounting and demounting of the steering wheel unit and the steering column in a case where the airbag has been mounted on the steering wheel frame of the steering wheel unit.
Also, the term "locked in a first direction" in this context means that relative movement of, for example, two members in the first direction is prevented. Specifically, the locking device 120 in the present invention locks the steering column 20, which passes through the through hole 1101, on the steering wheel unit 10 in the first direction D, means that the locking device 120 can prevent the relative movement of the steering column 20 with respect to the steering wheel unit 10 in the first direction D to prevent the steering column 20 from being detached from the steering wheel unit 10.
The locking device 120 in the steering wheel unit 10 according to the present invention is described in detail with reference to fig. 2.
As shown in fig. 2, a groove 210 is provided on a side surface of a head portion (i.e., one end portion) of the steering column 20, the groove 210 including an end surface 2101 and a side surface 2102. It can be understood that the end face 2101 and the side face 2102 of the groove 210 here are based on the orientation of the steering column 20, and specifically, the surface of the groove 210 that is substantially parallel to one end of the steering column 20 is regarded as an end face, and the surface of the groove 210 that is connected to the end face of the groove 210 is regarded as a side face.
As shown in fig. 1 and 2, the locking device 120 includes a molding 1201, a mounting pin 1202, and a mounting seat 1205. These components of the locking device 120 are described in detail below.
As shown in fig. 2, the molding portion 1201 of the locking device 120 has a first abutment surface that abuts the end surface 2101 of the groove 210 when the molding portion 1201 pivots from a first angle to a second angle with respect to the steering wheel frame 110 to lock the steering column 20 (i.e., the molding portion 1201 is in the orientation shown in fig. 2), and a second abutment surface that is interference-fitted with the side surface 2102 of the groove 210, at which time the first abutment surface of the molding portion 1201 is positioned perpendicular to the first direction D, and the second abutment surface is positioned along the first direction D. Thus, in the steering wheel system 1 of the present invention, the molded portion 1201 of the lock device 120 locks the steering column 20 on the steering wheel unit 10 in the first direction D by passing through both the supporting force at the first abutment surface and the frictional force at the second abutment surface.
As shown in fig. 1, mounting pins 1202 pass through mounting holes (not shown) of molding 1201, mounting pins 1202 are interference fit with the mounting holes of molding 1201, and pivotally mount molding 1201 to mount 1205 of steering wheel armature 110, where mount 1205 is fixedly mounted (e.g., welded) to steering wheel armature 110.
As one embodiment of the present invention, the side of the mount 1205 facing the steering column 20 is configured to mate with the outer surface of the steering column 20. That is, the outer surface of the steering column 20 is a cylindrical surface, and the side of the mount 1205 facing the steering column 20 is also configured as a segment of a cylindrical surface to avoid interference with the movement of the steering column 20 when the steering column 10 is mounted and dismounted.
As an embodiment of the present invention, the mount 1205 is specifically configured to include first and second spaced apart mount portions, and the molding 1201 is positioned between the first and second mount portions. It can be appreciated that this is advantageous for stable and evenly distributed support of the molding section 1201.
As an embodiment of the invention, for actuating the molding 1201 to pivot it, the locking device 120 further comprises a tool (not shown) and an actuating portion connected to the molding 1201, the actuating portion comprising a first actuating subsection 1203 and a second actuating subsection 1204, the molding 1201, the first actuating subsection 1203 and the second actuating subsection 1204 being configured in the form of blocks and being spaced apart in the circumferential direction of the mounting pin 1202 in sequence, and a first actuating face 1203A on the first actuating subsection 1203 and a second actuating face 1204A on the second actuating subsection 1204 being adjacent to each other and being used for actuating the molding 1201 in opposite directions, the tool applying a force to the first actuating face and the second actuating face, respectively, to cause the molding 1201 to pivot in opposite directions. For example, the tool is a rod.
Fig. 3 (a) -3 (d) schematically illustrate an assembly/disassembly process of a steering wheel assembly according to an embodiment of the present invention. The mounting/dismounting of the steering wheel assembly according to the embodiment of the present invention will be described with reference to fig. 3 (a) -3 (d).
As shown in fig. 3 (a), the steering column 20 moves upward from below to enter the through hole 1101 of the steering wheel frame 110 and continues to move beyond the steering wheel frame 110, at which time the molding portion 1201 of the locking device 120 is at a first angle with respect to the steering wheel frame 110; as shown in fig. 3 (b) -3 (c), in order to lock the steering column 20 on the steering wheel unit 10 in the first direction D, a force is applied with a tool to the second actuating surface of the second actuating portion 1024 such that the forming portion 1201 pivots from the position shown in fig. 3 (a) through the positions shown in fig. 3 (b) and 3 (c) until the position shown in fig. 3 (D); in the molding portion 1201 shown in fig. 3 (D), the molding portion 1201 of the locking device 120 is at the second angle with respect to the steering wheel frame 110, the first abutment surface of the molding portion 1201 abuts against the end surface 2101 of the groove 210, and the second abutment surface is in interference fit with the side surface 2102 of the groove 210, at which time the first abutment surface of the molding portion 1201 is positioned perpendicular to the first direction D and the second abutment surface is positioned along the first direction D, and therefore the molding portion 1201 locks the steering column 20 on the steering wheel unit 10 in the first direction D by both of the supporting force at the first abutment surface and the frictional force at the second abutment surface.
Conversely, if it is necessary to detach the steering column 20 from the steering wheel unit 10, a force is applied to the first actuating surface 1203A of the first actuating portion 1203 with a tool so that the forming portion 1201 pivots from the position shown in fig. 3 (d) through the positions shown in fig. 3 (b) and 3 (c) until the position shown in fig. 3 (a) and the steering column 20 moves downward from above to be separated from the through hole of the steering wheel frame 110.
It will be appreciated that in some cases, a retaining member may be provided for the shaped portion 1201 that is used to retain the shaped portion in a second angular position relative to the steering wheel frame 110. However, it is not essential to provide a holding member in the steering wheel unit of the present invention, considering that the steering wheel unit is mainly subjected to a force in the first direction, such as gravity, a downward force applied by the driver, or the like, after being mounted to the steering column.
Therefore, 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 frame, the steering column can still be mounted and dismounted in a simple and convenient manner.
