The vehicle-mounted device according to the embodiment of the present invention will be described using a navigation device 91 as an example. First, the general configuration of the navigation device 91 will be described with reference to Figures 1 to 3.

Figure 1 is a perspective assembly diagram of a navigation device 91, Figure 2 is a perspective diagram showing the navigation device 91, and Figure 3 is a top view of Figure 2. For ease of explanation, the up, down, left, right, front, and rear directions are defined as the directions indicated by arrows in Figure 1.

The navigation device 91 is a device mounted on a moving object such as a vehicle.

As shown in FIG. 1, the navigation device 91 has a main body 1 and a display unit 2. The main body 1 has a housing 11, and a connecting plate 12 and a connector 13 that protrude forward from the front surface of the housing 11.

The display unit 2 has a unit housing 21 and a base bracket 22 that protrudes rearward from the unit housing 21 and engages with the connecting plate 12.

The display unit 2 is connected to the main body 1 and integrated by engaging the base bracket 22 with the connecting plate 12 (see arrow DRa) and fastening the connecting plate 12 and the base bracket 22 with six fixing screws N1 to N6.

The connecting part RK is composed of the connecting plate 12, the base bracket 22, and the cover 3 described below.

Figures 2 and 3 show the main body 1 and the display unit 2 fixed together with the connecting part RK.

As shown in FIG. 2, the display unit 2 can be rotated within a predetermined angle range in the direction of the arrow DRb, allowing the user to change the position to their preference.

Next, the connecting portion RK will be described in detail. Figure 6 is a cross-sectional view taken along the line S6-S6 in Figure 3.

As shown in FIG. 6, the base bracket 22 has a top plate 22a, a back plate 22b, and a bottom plate 22c.

The top plate 22a is a plate-like portion extending in the front-rear and left-right directions. A pair of through holes 221, 222 spaced apart from each other in the front-rear direction is formed in the right part of the top plate 22a, and a pair of through holes 224, 225 spaced apart from each other in the front-rear direction is formed in the left part.

In addition, a pair of openings 223, 226 extending forward and backward are formed at positions spaced apart on the left and right sides of the front part of the top plate 22a. The openings 223, 226 are cut from the front to the rear, and therefore, for convenience, are also referred to as cut-out parts 223, 226 in the following description.

The bottom plate 22c is disposed below and parallel to the top plate 22a, and is connected to the top plate 22a at the front via the back plate 22b.

Female thread portions 22c1 are formed as first female thread portions at positions on the bottom plate 22c that correspond to the notches 223 and 226 on the top plate 22a.

As shown in FIG. 4, the board 5 is attached to the rear plate 22b of the base bracket 22 by a mounting structure (not shown). The receptacle 6, which is the other connecting member that engages with the connector 13, is attached to the board 5 so as to protrude rearward.

In the back plate 22b, female threads 22b1 are formed on the left and right sides of the receptacle 6.

As shown in Figures 3 and 4, a cover 3 is attached to the rear plate 22b of the base bracket 22. The cover 3 also serves to hide the circuit board 5 and other components from view of the user, so in the following explanation, it is also referred to as the blind cover 3 for convenience.

As shown in FIG. 4, the privacy cover 3 has a base 3a that extends in a long rectangular shape from side to side, a right guide portion 3b that is connected to the right end of the base 3a, and a left guide portion 3c that is connected to the left end of the base 3a.

The base 3a has an opening 3a1 in the center that is shaped to fit the receptacle 6 and through which the receptacle 6 can be inserted, and stepped screw seat portions 3a2 formed on the left and right sides of the opening 3a1 and each having a through hole 3a2a.

Board abutments 3d are formed at both left and right ends of the front surface of the base 3a, protruding forward and engaging with the left and right edges of the board 5.

The right guide portion 3b is formed with a rib 3b1 that protrudes backward. The rib 3b1 prevents the blind cover 3 from being attached in the wrong direction and also makes it easier to grip the blind cover 3, improving work efficiency.

As shown in FIG. 4, the cover 3 is attached to the rear plate 22b by passing the receptacle 6 through the opening 3a1 and threading the fixing screw N7 through the through hole 3a2a of the screw seat 3a2 and fastening it to the female threaded portion 22b1 of the rear plate 22b.

The right guide portion 3b and the left guide portion 3c are formed in the shape of a portion of the circumferential surface of a cylinder having an axis that extends vertically. The axis of this cylinder coincides with the axis CLa of the female thread portion 22c1 when the cover 3 is attached to the back plate 22b.

Next, the engagement relationship between the connecting plate 12 and the base bracket 22 will be described with reference to Figure 5. Figure 5 is a cross-sectional view of the base bracket 22 with the cover 3 attached engaged with the connecting plate 12 at the S5-S5 position shown in Figure 4.

First, as shown in FIG. 1, the connecting plate 12 has a flat base 12a that extends forward, backward, left and right, and arm plate portions 12b and 12c that are connected to the left and right ends of the base 12a and are formed in an inverted L shape that extends outward from the top.

The arm plate portion 12b has a pair of second female threaded portions 121, 122 formed at a distance in the front-rear direction, and the arm plate portion 12c has a pair of second female threaded portions 124, 125 formed at a distance in the front-rear direction.

The base 12a has through holes 123, 126 at positions close to the arm plate portions 12b, 12c on the front edge side.

The connector 13 is installed above the base 12a and protrudes forward.

When engaging the base bracket 22 with the cover 3 attached to the connecting plate 12, insert and engage the lower surface 12a1 of the base 12a of the connecting plate 12 so that it abuts on the upper surface of the bottom plate 22c of the base bracket 22, as shown in Figure 6 as a reference.

By this insertion operation, the receptacle 6 engages and connects to the connector 13. In addition, the upper surfaces 12b1, 12c1 (see FIG. 5) of the arm plate portions 12b, 12c of the connecting plate 12 closely face the lower surface 22a1 (see FIG. 6) of the top plate 22a of the base bracket 22 with almost no gap between them.

The positions of the through holes 221, 222 in the top plate 22a correspond to the positions of the female threaded portions 121, 122 of the arm plate portion 12b of the connecting plate 12, and the positions of the through holes 224, 225 correspond to the positions of the female threaded portions 124, 125 of the arm plate portion 12c.

The positions of the through holes 123, 126 in the base 12a of the connecting plate 12 correspond to the positions of the female threaded portions 22c1, 22c1 in the bottom plate 22c of the base bracket 22. In this state, the female threaded portions 22c1, 22c1 can be seen from above through the notches 223, 226 in the top plate 22a.

As a result, the screws N1 and N2 are fastened to the female threaded portions 121 and 122 through the through holes 221 and 222, and the screws N4 and N5 are fastened to the female threaded portions 124 and 125 through the through holes 224 and 225.

The screws N3 and N6 are then passed through the notches 223 and 226, and then through the through holes 123 and 126 of the connecting plate 12, and fastened to the female threads 22c1 and 22c1 of the bottom plate of the base bracket 22.

The base bracket 22 is securely attached to the connecting plate 12 by fastening these six screws. In other words, the display unit 2 is attached to the main body 1.

As shown in FIG. 6, the fixing screw N6 is tightened by inserting it from above the top plate 22a of the base bracket 22 through the notch 226 while the fixing screw N6 is engaged and held at the tip of the driver bit 81, into the female threaded portion 22c1 of the lower bottom plate 22c. The same applies to tightening the fixing screw N3.

The connecting part RK has a cover 3, and the right guide part 3b and the left guide part 3c of the cover 3 are arranged to surround the insertion paths of the fixing screws N3 and N6 from above, respectively, as shown in FIG. 5.

In other words, the insertion path of the fixing screw N3 is set within a closed cylindrical guide space SP1 that extends vertically and is surrounded by the back plate 22b at the front, the arm plate portion 12b of the connecting plate 12 at the right, and the right guide portion 3b at the rear and left as a side wall.

The insertion path of the fixing screw N6 is similarly set as a closed cylindrical guide space SP2 extending vertically, surrounded by the back plate 22b at the front, the arm plate portion 12c of the connecting plate 12 at the left, and the left guide portion 3c as a side wall at the rear and right.

As a result, even if the fixing screws N3, N6 come off the bit 81 while moving downward within the guide spaces SP1, SP2 when tightening the fixing screws N3, N6, they can be easily retrieved.

In other words, the guide spaces SP1 and SP2 are essentially closed spaces separated from other spaces with respect to the fixing screws N3 and N6, so the fixing screws N3 and N6 remain within the guide spaces SP1 and SP2 and do not roll and move to other areas.

As a result, the fixing screws N3 and N6 can be easily removed even if they come off the bit 81, and can be easily refastened. This allows the navigation device 91 to perform screw fastening work between the main body 1 and the display unit 2 with high efficiency.

The cover 3 covers the board 5 except for the opening 3a1 through which the receptacle 6 is inserted, so that the board 5 cannot be seen from the outside.

This prevents metal parts from entering and contacting the board 5 from the outside, causing problems such as short circuits.

The embodiment described above is not limited to the above configuration, and may be modified without departing from the spirit of the present invention.

The type of fixing screws N1 to N7 is not limited. For example, the fixing screws passed through the guide spaces SP1 and SP2 may be cross recessed hex screws with hexagonal heads, and the guide spaces SP1 and SP2 may be formed to a size that allows the insertion of a box wrench that fits the hexagonal head of the cross recessed hex screw of the fixing screw N7. In other words, the guide spaces SP1 and SP2 are formed so that a tool for tightening the fixing screw N7 can be inserted.

The direction in which the fixing screw N7 held by the bit 81 is moved is not limited to the direction of gravity, which is from top to bottom. It may be inclined or perpendicular to gravity. In other words, the direction in which the axis of the guide spaces SP1 and SP2 extends (first direction) is not limited to the up-down direction.

In the embodiment, as shown in FIG. 4, the substrate 5 is oriented to extend in the up-down and left-right directions, and an upright receptacle 6 is mounted on the substrate 5, but the orientation of the substrate 5 is not limited. For example, the substrate 5 may be oriented to extend in the left-right and front-rear directions, and a face-down receptacle 6 may be mounted on the substrate 5.

The relationship between the receptacle 6 and the connector 13 described in the embodiment and the modified example may be reversed. That is, the receptacle 6 may be on the main body 1 side, and the connector 13 may be on the display unit 2 side.
