Description
Technical field
The present invention relates to for motor vehicles horn switch device and including the steering wheel assembly of horn switch device.
Background technology
Figure 1A and Figure 1B shows the details of a kind of horn switch device and its contacting board component in the prior art.Figure 1A is
Show that the sectional view of horn switch device 100 according to prior art, Figure 1B are to show horn switch dress according to prior art
The vertical view for the contacting board component set.The horn switch device 100 can be used for the steering wheel assembly of motor vehicles, by
Turning circuit when enough pressing forces.As shown in Figure 1A, horn switch device 100 includes pressing component 1, spring element 2 and connecing
Touchpad assembly 3.Contacting board component 3 includes electrically isolated from one and the first contact plate 3a and the second contact plate in face of pressing component
3b.Second contact plate 3b extends around the first contact plate 3a, and both is formed as one by way of molding.For example,
It is formed as one by by the injection molding around contact plate of insulative molding material 5.First contact plate 3a and the second contact plate
3b is connected respectively to the two poles of the earth of power supply (not shown).Spring element 2 is pressing component 1 around the part setting for pressing component 1
Between the second contact plate 3b, one end of spring element 2 against and be electrically connected press component 1 and its other end against and be electrically connected
Meet the second contact plate 3b.When pressing component 1 not by outer force effect, the holding of spring element 2 presses component 1 and contacting board component 3
Between interval, to keep the first contact plate 3a and the second contact plate 3b electric isolution.When pressing component 1 by pressed by external force
When, it presses component 1 and is in contact with the first contact plate 3a, to which the first contact plate 3a to be electrically connected with the second contact plate 3b.
When one contact plate 3a is electrically connected with the second contact plate 3b, the circuit turn-on of loudspeaker, to which loudspeaker make a sound.
Referring next to Figure 1B, when by by molding material 5 around the first contact plate 3a and the second contact plate 3b injection mould
When processed, molding material 5 would generally cover the part surface (part A in such as Figure 1B towards spring element 2 of the second contact plate 3b
It is shown).When the area that molding material 5 covers the second contact plate 3b is excessive, spring element 2 and the second contact plate may be influenced
Electrical connection between 3b, even results in poor contact.In the case, when pressing component 1 by pressed by external force, spring element
2 and second poor contact between contact plate 3b and cause switch can not work normally, especially only connect with second in spring element 2
In the case that molding material 5 on the surfaces touch panel 3b is in contact.As a result, the first contact plate 3a and the second contact plate 3b can not be electrically connected
It connects, and therefore the circuit of loudspeaker can not also be connected.
In order to solve problem above, the technical solution of the prior art introduces washer 4.Specifically, the setting of washer 4 is the
It is in contact on the surface towards spring element 2 of two contact plate 3b and with the surface, and one end of spring element 2 is against washer
4.Washer 4 increases the contact area with the second contact plate 3b.In this way, when pressing component 1 by pressed by external force, bullet
Spring element 2 can be indirectly electrically connected by washer 4 with the second contact plate 3b, and the problem of not easily lead to poor contact.As a result,
The circuit of loudspeaker can be connected.
However, the prior art for avoiding loudspeaker that from can not being connected by introducing washer 4, due to introducing additional portion
Part so that the structure of horn switch device is more complicated.

There is space between 321n and the peripheral surface for pressing column 310.In this way, when U-shaped portion 321 is in company with pressing column 310 together
When being pressed, wide opening part 321n has deformation space.When the distance between the first protrusion 321a and the first contact plate 341 are the same as the
When two protrusion 321b are different from the distance between the second contact plate 342, pass through the deformation of wide opening part 321n so that the first protrusion
321a and the second protrusion 321b can be in contact with contacting board component 340.
Fig. 3 D are the partial perspective views for showing horn switch device 300 according to an embodiment of the invention.According to the present invention
Embodiment, the end towards contacting board component 340 for pressing column 310 is provided with lug boss 311, the lug boss 311 with support
By the first protrusion 321a.When pressing column 310 by pressed by external force, lug boss 311 is against the first protrusion 321a, so that it is guaranteed that first
Protrusion 321a is in contact with the first contact plate 341.
Fig. 3 E are the structural schematic diagrams for showing the first protrusion 321a according to an embodiment of the invention and the second protrusion 321b.
According to an embodiment of the invention, the distance between the first protrusion 321a and the first contact plate 341 are more than the second protrusion 321b and the
The distance between two contact plates 342, preferably big 0.3mm.When pressing column 310 by pressed by external force, two of the end of bottom wall
Two protrusion 321b are in contact with the second contact plate 342 first.Then, since lug boss 311 is against the first protrusion 321a, first is prominent
321a is played also to be in contact with the first contact plate 341.
Referring again to Fig. 3 C, mobile contact component 320 further includes two curved portions 322, and each of curved portion 322 is equal
It is connected with the free end 321p of U-shaped portion 321 and perpendicular with U-shaped portion 321.In this way, at least one of column 310 is pressed
Partial volume is contained in mobile contact component 320.
Referring again to Fig. 3 B, press column 310 be configured to it is ladder-like and from pressing the peripheral surface of column 310 mandrel thereto
The direction of line has the first shoulder 312 and the second shoulder 313 successively.Spring element 330 is against the first shoulder 312, and arc
Portion is against second shoulder 313.With this embodiment, spring element 330 will not interfere with each other for 321 with U-shaped portion.But
The present invention is not limited thereto.For example, curved portion 322 can be located at same shoulder with column 310 is pressed, and spring element 330 supports
By curved portion 322.
<3rd embodiment>
Then, the 3rd embodiment of the horn switch device of the present invention is described in detail with reference to Fig. 4 A to Fig. 4 D.Figure
