Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following detailed description and drawings are illustrative of the principles of the invention, which is not limited to the embodiments described, but is defined by the claims.
In the following description, it is assumed that the extending direction of a steering wheel panel (a cover plate of an airbag module provided in a steering wheel) is a lateral direction, wherein the lateral direction is substantially perpendicular to the extending direction of a steering shaft of the steering wheel.
Fig. 1, 2A-2B and 3A-3B show an airbag module 1 according to the prior art arranged in a vehicle steering wheel, wherein fig. 1 shows the airbag module 1 in an assembled state as seen from the underside in the direction of extension of the steering shaft of the steering wheel, fig. 2A-2B show the cover 10 and the housing 20 of the airbag module 1, respectively, fig. 3A shows the individual components of a horn switch assembly 30 of the airbag module 1, and fig. 3B shows a partial sectional view of the horn switch assembly 30 in the assembled state. Specifically, as shown in fig. 1 and 2A-2B, the cover plate 10 and the housing 20 can be coupled together to form a space for accommodating an air bag (not shown). The cover plate 10 is connected to the housing 20 by the rectangular hole 11 provided on the lateral extension thereof (substantially in the extending direction of the steering wheel shaft) being engaged with the hook portion 21 provided on the lateral extension of the housing 20 (substantially in the extending direction of the steering wheel shaft), and in the connected state, the cover plate 10 is movable relative to the housing 20 in the extending direction of the steering wheel shaft. The cover plate 10 is provided with a pin 12 which, in the assembled state of the airbag module 1, is aligned with and can be brought into contact with the horn switch assembly 30. The horn switch assembly 30 can be accommodated in the horn accommodating portion 22 of the housing 20. As shown in fig. 3A, the horn switch assembly 30 specifically includes a sleeve 31, a fitting spring 32, a movable member 33, a movable metal sheet 34, a biasing spring 35, a metal gasket 36, a first metal sheet 37, and a second metal sheet 38. More specifically, as shown in fig. 3B, the movable metal piece 34 is mounted on the movable piece 33, and is movable together with the movable piece 33; the bias spring 35 is sleeved on the periphery of the lower cylinder of the movable member 33, the upper end of the bias spring abuts against the flange in the middle of the movable member 33, and the lower end of the bias spring abuts against the metal gasket 36; the metal gasket 36 is in close contact with the first metal sheet 37 without contacting the second metal sheet 38; and the first metal piece 37 and the second metal piece 38 are respectively connected to the positive and negative poles of the power supply and are arranged to be electrically isolated from each other. In the non-operating state of the horn switch assembly 30, the movable member 33 is biased by the biasing spring 35 to an initial position in which the movable metal piece 34 is not in contact with the first and second metal pieces 37, 38, and the first and second metal pieces 37, 38 are in an electrically isolated state; when the cover plate 10 is pressed, the pin 12 pushes the sleeve 31 downward, causing the movable member 33 to move downward and thereby bring the movable metal piece 34 into contact with the first and second metal pieces 37, 38, thereby electrically connecting the first and second metal pieces 37, 38 and sounding the horn.
In assembling the airbag module 1, it is necessary to first fit the horn switch assembly 30 into the horn receiving portion 22 from the opening above the horn receiving portion 22 and then attach the cover plate 10 to the case 20. When the cover plate 10 and the housing 20 are coupled, the cover plate 10 needs to be moved downward by a certain assembly stroke in order to catch the rectangular holes 11 on the hooks 21. However, the horn switch assembly 30 limits the downward movement range of the cover plate 10, and the assembly stroke exceeds the compression stroke of the biasing spring 35. Therefore, in order to provide a sufficient assembly stroke, a sleeve 31 and an assembly spring 32 between the sleeve 31 and the movable member 33 are additionally provided. When the cover plate 10 is assembled, the cover plate 10 is pressed downward relative to the housing 20 so that the assembly spring 32 is also contracted in addition to the biasing spring 35 to provide a sufficient assembly stroke. In addition, since the rigidity of the mounting spring 32 is much greater than that of the biasing spring 35, no deformation occurs during normal operation of the horn switch assembly 30, and thus normal operation of the horn switch assembly 30 is not affected. The above configuration provides a sufficient assembly stroke for the installation of the cover plate, but causes the horn switch assembly 30 to additionally include parts unnecessary in operation, thereby increasing the production cost.
Embodiments of the present invention provide an improved airbag module provided in a steering wheel of a vehicle, in which an assembly manner of the airbag module is changed by improving a structure of a horn switch assembly, and thus an additional component for implementing an assembly stroke can be omitted, thereby reducing a production cost.
An airbag module according to an embodiment of the present invention includes an airbag, a cover and a case connected to each other to form a space for accommodating the airbag, and a horn switch assembly. In which an airbag module according to an embodiment of the present invention is configured such that a cover is movable relative to a housing in an extending direction of a steering shaft of a steering wheel, and pressing the cover can electrically conduct a horn switch assembly, thereby sounding a horn.
Fig. 4A shows an overall schematic view of a horn switch assembly of an airbag module according to an embodiment of the present invention, and fig. 4B shows a perspective view of a movable member of the horn switch assembly shown in fig. 4A. As shown in fig. 4A-4B, the horn switch assembly 40 includes a tubular member 41, a movable member 42, a movable metal sheet 43, a first metal sheet 44, a second metal sheet 45, and a biasing spring 46. In particular, the tubular member 41 is provided with an opening 411 on a side surface thereof, wherein at least the movable piece 42, the movable metal sheet 43 and the biasing spring 46 can be fitted into the tubular member 41 via this opening 411. The movable member 42 may be formed, for example, in a substantially stepped shaft shape including two cylindrical portions different in diameter, wherein the diameter of the upper cylindrical portion 421 is larger than the diameter of the lower cylindrical portion 422. Also, the movable member 42 is sized to be movable in the axial direction within the tubular member 41. The movable sheet metal 43 is fixed to the lower cylindrical portion 422 of the movable member 42, and can move together with the movable member 42. A first metal sheet 44 and a second metal sheet 45 are arranged near the bottom of the tubular member 41, which are connected to the positive and negative poles of a power supply, respectively, and are arranged to be electrically isolated from each other. The biasing spring 46 is fitted over the outer periphery of the lower cylindrical portion 422 of the movable member 42, wherein the upper end of the biasing spring 46 abuts against the step face 423 in the middle of the movable member 42, and the lower end abuts against the bottom of the tubular member 41 and is out of contact with both the first and second metal sheets 44, 45. In the non-operating state of the horn switch assembly 40, the movable member 42 is biased by the biasing spring 46 at the initial position where the movable metal piece 43 is not in contact with the first and second metal pieces 44, 45 and the first and second metal pieces 44, 45 are electrically isolated. When the movable member 42 is pressed downward, the movable member 42 moves toward the bottom of the tubular member 41, causing the movable metal piece 43 to simultaneously contact the first and second metal pieces 44, 45, electrically connecting the first and second metal pieces 44, 45, thereby electrically conducting the horn switch assembly 40 to sound the horn.
Further, it will be understood by those skilled in the art that the structure of the movable member 42 is not limited to the specific structure described above, and other suitable structures adapted to the function thereof may be employed. The arrangement of the movable metal piece, the first metal piece, the second metal piece, and the biasing spring is also not limited to the arrangement described above, and other suitable arrangements may be adopted. For example, the horn switch assembly 40 may not include the movable metal sheet 43, and the movable member 42 itself may be electrically conductive. Thus, the movable member 42 can be pressed downward into contact with both the first and second metal pieces 44, 45, thereby electrically connecting the first and second metal pieces 44, 45 and electrically connecting the horn switch assembly 40. Further, in the above-described embodiment, the biasing spring 46 is disposed with its lower end abutting against the bottom of the tubular member 41 and not in contact with both the first and second metal sheets 44 and 45, but the biasing spring 46 may be disposed with its lower end abutting against the second metal sheet 45 and not in contact with the first metal sheet 44.
Further, the tubular member 41 of the horn switch assembly 40 according to the above-described embodiment may be connected integrally with the housing of the airbag module. In particular, the tubular member 41 may be formed as a single integral part with the housing of the airbag module or attached to the housing as a separate component. In this case, the tubular member 41 may be disposed such that the axial direction thereof coincides with the extending direction of the steering shaft of the steering wheel, and the opening 411 on the side surface of the tubular member 41 faces in the lateral direction. Furthermore, the cover plate of the airbag module may comprise a pin which is aligned with and contactable with the movable member 42 via the upper opening 412 of the tubular member 41 in the assembled state of the airbag module. When the cover is pressed, the cover moves downward relative to the housing, and the pin portion of the cover forces the movable member 42 toward the bottom of the tubular member 41, causing the movable metal piece 43 to simultaneously contact the first and second metal pieces 44, 45, electrically connecting the first and second metal pieces 44, 45, thereby electrically connecting the horn switch assembly 40 to sound the horn.
In assembling the airbag module according to the above-described embodiment, the cover plate may be first attached to the housing, and then other components such as the movable piece 42 of the horn switch assembly 40 may be installed in the tubular member 41 in the lateral direction via the opening 411 on the side surface of the tubular member 41. In this way, since there is no other part in the tubular member to limit the downward movement range of the cover plate when the cover plate is mounted, a sufficient assembly stroke can be provided for the cover plate. Therefore, the number of parts of the horn switch assembly can be reduced, and the production cost can be reduced.
It is to be noted that, in order to enable the movable member 42 to be mounted into the tubular member 41 in the lateral direction via the opening 411 without coming out of the opening 411 due to the bumping or the vibration of the vehicle, the opening 411 is provided such that the opening width thereof is slightly smaller than the maximum outer diameter of the movable member 42. In this way, at the time of assembly, it is possible to press the movable member 42 through the opening 411 with a large force (larger than that applied by bumping or vibration of the vehicle in a normal case) while ensuring that the movable member 42 can move moderately freely in the tubular member 41 and does not come out from the tubular member 41. Accordingly, the movable member 42 may be formed of a material capable of providing suitable elastic deformation, such as plastic or the like.
Fig. 5 shows an overall schematic view of a horn switch assembly 50 of an airbag module according to another embodiment of the present invention, and fig. 6A and 6B show perspective views of a tubular member and a movable member of the horn switch assembly shown in fig. 5, respectively. The basic configuration of the horn switch assembly according to the present embodiment is substantially the same as that of the horn switch assembly according to the embodiment shown in fig. 4, except that the movable member of the horn switch assembly according to the present embodiment is provided with a fitting portion, the tubular member is provided with a lateral fitting portion, and the movable member can be guided to be fitted into the tubular member by the fitting portion being fitted with the lateral fitting portion. Specifically, as shown in fig. 5 and 6A-6B, the fitting portion of the movable member 52 of the horn switch assembly 50 may be formed as a protrusion 521 provided on the outer surface of the movable member 52, and the lateral fitting portion of the tubular member 51 is formed as a groove 511 extending in the lateral direction on the inner surface of the tubular member 51. When the movable member 52 is installed into the tubular member 51 in the lateral direction through the opening 512 of the tubular member 51, the movable member 52 is installed into the tubular member 51 guided along the groove 511 by aligning the projection 521 with the groove 511 and pushing the movable member 52 toward the inside of the tubular member 51. Such a guiding installation makes it possible to make the installation of the movable member 52 to the tubular member 51 more convenient and stable.
Further, the tubular member of the horn switch assembly according to the present embodiment may further include an axial fitting portion with which the movable member is able to move in the axial direction of the tubular member by the fitting portion being fitted. Specifically, as shown in fig. 6A, the axial fitting portion of the tubular member 51 may be formed as a groove 513 extending in the axial direction of the tubular member 51 on the inner surface of the tubular member 51. The movable member 52, after being mounted into the tubular member 51, is movable in the axial direction of the tubular member 51 in a state where the projection 521 is engaged with the recess 513. The engagement of the projection 521 with the recess 513 makes the movement of the movable member 52 in the axial direction with respect to the tubular member 51 smoother. In addition, the engagement of the protrusion 521 and the recess 513 also fixes the position of the movable member 52 relative to the tubular member 51, which can reduce the rotation and inclination of the movable member 52 in the tubular member 51, and is beneficial to preventing the movable member 52 from being removed from the tubular member 51.
In addition, in order to further prevent the movable member 52 from coming out of the tubular member 51 through the opening 512 due to the bumping and shaking of the vehicle, etc., the recess 511 of the tubular member 51 is specially designed. Specifically, the position of the recess 511 relative to the recess 513 is set between two extreme positions at which the projection 521 of the movable member 52 moves along the recess 513, so as to reduce the chance of the projection 521 accidentally entering the recess 511. Further, the groove 511 is sized such that the width toward one end of the opening 512 is greater than the width at the other end. Thus, alignment of the protrusion 521 with the recess 511 can be facilitated when the movable member 52 is mounted, and difficulty in entering the protrusion 521 into the recess 511 can be increased during use. In addition, a stopper structure such as a small protrusion may be further provided on the surface of the groove 511. Thus, even if the projection 521 accidentally enters the recess 511, it cannot slide along the recess 511 toward the opening side, thereby further preventing the movable member 52 from coming out of the tubular member 51.
Preferably, as shown in fig. 6B, the fitting portion of the movable member 52 may include a pair of protrusions 521, 521' symmetrically arranged in the circumferential direction of the movable member 52. In this case, the lateral fitting portion of the tubular member 51 is formed as a pair of grooves 511, 511 'symmetrically arranged on both sides of the opening 512, and the axial fitting portion of the tubular member 51 is formed as a pair of grooves 513, 513' symmetrically arranged in the inner circumferential direction of the tubular member 51.
Furthermore, movable member 52 may also include a removal portion to facilitate removal of movable member 52 from tubular member 51. Specifically, as shown in fig. 5 and 6A-6B, the detaching portion is formed as a projection 522 provided on the outer surface of the movable member 52. Wherein the projection 522 is provided in a shape different from the projections 521, 521' as the fitting portion, and the projection 522 faces the opening 512 side in a state where the movable member 52 is fitted into the tubular member 51.
Further, the upper cylindrical portion of the movable piece 52 may be formed to be hollow, and a rib 523 (shown in fig. 6B) may be provided inside the hollow. By providing the rib, the contact area of the upper surface of the movable member with the pin portion on the cover plate can be increased, so that the movable member can be effectively pressed even in the case where the movable member is inclined or the like.
Further, in the above-described embodiment, the cover plate is movable relative to the housing of the airbag module in the extending direction of the steering shaft. However, the above embodiment is also suitable for the case where the entire airbag module is movable in the direction of the steering shaft of the steering wheel.
While the invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the construction and methods of the embodiments described above. On the contrary, the invention is intended to cover various modifications and equivalent arrangements. In addition, while the various elements and method steps of the disclosed invention are shown in various example combinations and configurations, other combinations, including more, less or all, of the elements or methods are also within the scope of the invention.
