Detailed Description

First embodiment

A first embodiment of the present invention will be described below with reference to fig. 1 to 7.

As shown in fig. 1 to 3, an outer contour of the switch module 12 attached to an instrument panel 11 (shown by a thick two-dot chain line in fig. 3) of an automobile includes a base member 13 (shown by a thick dashed line in fig. 3) and a case member 14. The case member 14 is fitted to the base member 13 so as to cover the base member 13. In the following description, the side facing the vehicle interior when the switch module 12 is mounted on the vehicle body is referred to as the front side, the opposite side is referred to as the rear side, and the upper, lower, left, and right directions viewed from the occupant are referred to as the upper, lower, left, and right directions of the switch module 12, respectively.

The case member 14 is positioned so as to fit into the opening 11a of the instrument panel 11, and 6 mounting brackets 14a protruding from the outer periphery of the case member 14 are fastened to the instrument panel 11.

One dial 15 and three push switches 16 to 18 are disposed on the front surface of the case member 14, and a garnish 20 is attached to the right side of one push switch 18. The garnish 20 is fitted into a garnish attachment hole 14b opened in the front surface of the case member 14 and fixed by a locking claw, not shown, so as not to fall off.

As shown in fig. 3, an antenna member 21 having a substantially rectangular parallelepiped shape is housed inside the case member 14 covered with the garnish 20. The antenna unit 21 is used, for example, for Near-field-communication (Near-field-communication) between smartphones in the vicinity thereof. As shown in fig. 7, the garnish 20 is designed on the front surface thereof, and a plate-shaped locking projection 20a extending in the left-right direction is provided on the rear surface of the garnish 20 in a protruding manner.

As shown in fig. 6, the antenna member 21 is a substantially rectangular parallelepiped member including a front surface 21a, a rear surface 21b, an upper surface 21c, a lower surface 21d, and left and right side surfaces 21e and 21f, and a cable 23 with a connector 22 extends from the lower surface 21 d. A first engaging projection 21g having a T-shaped fixed cross section when viewed in the vertical direction is provided to protrude from a central portion of the front surface 21a of the antenna member 21, and second engaging projections 21h and 21i linearly extending in the vertical direction are provided to protrude from the left and right side surfaces 21e and 21f of the antenna member 21.

As shown in fig. 3 to 5, an antenna member insertion hole 24 that opens to the lower surface of the case member 14 is formed in the vertical direction inside the base member 13 and the case member 14, and the antenna member insertion hole 24 communicates with the garnish attachment hole 14b of the case member 14.

A first engaging groove 14c having a T-shaped cross section and engageable with the first engaging projection 21g of the antenna member 21 is formed in a portion of the case member 14 constituting the wall surface of the antenna member insertion hole 24, and a pair of linear second engaging grooves 13a and 13b engageable with the pair of second engaging projections 21h and 21i of the antenna member 21 are formed in a portion of the base member 13 constituting the wall surface of the antenna member insertion hole 24.

Next, an operation of the embodiment of the present invention having the above-described configuration will be described.

In order to assemble the antenna member 21 to the switch module 12, the antenna member 21 is inserted into the antenna member insertion hole 24 opened in the lower surface of the case member 14 in a state where the dial 15 and the push switches 16 to 18 are assembled to the base member 13 and the case member 14 which are integrated. At this time, the first engaging projection 21g of the T-shaped cross section of the antenna member 21 is guided while sliding in a state of being fitted in the first engaging groove 14c of the T-shaped cross section of the case member 14, and the pair of second engaging projections 21h and 21i of the antenna member 21 is guided while sliding in a state of being fitted in the pair of second engaging grooves 13a and 13b of the base member 13.

After the antenna member 21 is inserted to the end of the antenna member insertion hole 24, the garnish 20 is fitted into the garnish attachment hole 14b of the case member 14 and fixed to the garnish attachment hole 14b by a locking claw, not shown. As a result, the locking projection 20a provided on the back surface of the garnish 20 projects into the antenna member insertion hole 24 and comes into contact with the lower surface of the first engagement projection 21g of the antenna member 21, thereby preventing the antenna member 21 from coming off the antenna member insertion hole 24 (see fig. 3 to 5). The switch module 12 assembled in this way is positioned at the opening 11a of the instrument panel 11 so that the dial 15, the push switches 16 to 18, and the garnish 20 face the vehicle interior, and is fixed to the instrument panel 11 by the mounting bracket 14a of the case member 14.

As described above, according to the present embodiment, the antenna member 21 inserted into the antenna member insertion hole 24 is fixed by the garnish 20 as the decorative member so as not to fall off, and therefore, a special member for fixing the antenna member 21 is not required, thereby reducing the number of components. At this time, the antenna member 21 is inserted from the lower side to the upper side, and the garnish 20 is inserted from the front side to the rear side. That is, the insertion direction of the antenna member 21 and the insertion direction of the garnish 20 are orthogonal to each other. Thus, even if the cable 23 is pulled and a load in the detachment direction acts on the antenna member 21, the garnish 20 does not detach from the garnish attachment hole 14b, and detachment of the antenna member 21 is reliably prevented.

According to the present embodiment, the first engaging projection 21g of the antenna member 21 is engaged with the first engaging groove 14c of the case member 14, and the second engaging projections 21h and 21i of the antenna member 21 are engaged with the second engaging grooves 13a and 13b of the base member 13, whereby the case member 14 and the base member 13 are positioned with respect to each other via the antenna member 21.

Further, the base member 13 and the case member 14 are basically joined at their outer peripheries, but there is a portion of the case member 14 that is not connected to the outer periphery of the base member 13. Therefore, the stiffness of the unconnected portion may be reduced and the unconnected portion may be easily bent. However, according to the present embodiment, the portion of the case member 14 that is not connected to the outer peripheral portion of the base member 13 and the base member 13 are integrated via the antenna member 21, and thus the rigidity of the case member 14 is improved and the case member is less likely to be bent.

In particular, since the first engaging projection 21g and the first engaging groove 14c have a T-shaped cross section, the housing member 14 and the antenna member 21 are accurately positioned so as not to be relatively movable in both the vertical direction and the lateral direction, and the antenna member 21 can be more firmly coupled to the housing member 14.

Second embodiment

Hereinafter, a second embodiment of the present invention will be described with reference to fig. 8.

In the second embodiment, the base member 13 and the case member 14 are smaller than those of the first embodiment, and the garnish 20 is provided at a position close to one end of the case member 14. The front face of the case member 14 protrudes from the design face of the instrument panel 11 into the vehicle compartment, and therefore the garnish 20 also protrudes from the design face of the instrument panel 11 into the vehicle compartment.

According to the present embodiment, since the garnish 20 covering the antenna member 21 is provided at a position near the end of the case member 14 and the garnish 20 protrudes from the design surface of the instrument panel 11 into the vehicle compartment, when a person seated in the driver's seat or the passenger's seat approaches the vehicle by holding the smartphone with his or her hand, fingers are less likely to hit the design surface of the instrument panel 11, and operability is improved.

The same effects can be obtained not only for a smartphone but also for a wearable device such as an IC card or a smart watch as long as the portable terminal can communicate with the outside.

While the embodiments of the present invention have been described above, the present invention can be variously modified in design without departing from the scope of the present invention.

For example, in the embodiment, the switch module 12 is attached to the instrument panel 11, but the object to which the switch module 12 is attached is arbitrary.

In the embodiment, the antenna member 21 is provided on the base member 13 and the case member 14 of the switch module 12 including the dial 15 and the push switches 16 to 18, but the antenna member 21 may be provided on a dedicated base member 13 and case member 14.

The number of the first engaging projections 21g and the first engaging grooves 14c is not limited to 1, and the number of the second engaging projections 21h and 21i and the number of the second engaging grooves 13a and 13b are not limited to 2.

The insertion direction of the antenna member 21 and the fitting direction of the garnish 20 do not necessarily need to be orthogonal to each other, and may intersect each other.

The cross-sectional shapes of the first engaging projection 21g and the first engaging groove 14c are not necessarily T-shaped, and may be other shapes such as L-shaped, Y-shaped, and X-shaped.

The communication standard of the antenna unit 21 is not limited to Near-field-communication (Near-field-communication), and may be various other wireless communication standards such as Bluetooth (registered trademark).
