[0005] Patent Document 1: Japanese Patent Application Publication No. 2013-199199 Summary of the invention

[0006] In the past, the vehicle-mounted device was fixed by screwing a vehicle mounting bracket screwed to its side to the vehicle-side fixing part. If there is a positional offset between the instrument panel and the vehicle-mounted device panel, it will affect the aesthetics. Therefore, in order not to hinder the positional restriction of the instrument panel and the vehicle-mounted device, it is necessary to install the vehicle mounting bracket on the instrument panel and not to position the vehicle mounting bracket relative to the vehicle-mounted device. Therefore, the positional relationship between the vehicle-mounted device and the vehicle mounting bracket depends on the positional relationship between the vehicle-mounted device and the instrument panel. For example, when the positional relationship between the vehicle-mounted device and the instrument panel deviates, the positional relationship of the mounting hole on the vehicle mounting bracket side relative to the threaded hole on the vehicle-mounted device side is offset, and the threaded fixing cannot be performed, and the vehicle mounting bracket cannot be installed on the vehicle-mounted device. If the mounting hole on the vehicle mounting bracket side is enlarged to avoid this situation, when the vehicle-mounted device and the vehicle mounting bracket are fastened, the seat surface of the screw and the grounding surface of the vehicle mounting bracket become smaller, and the required fastening force cannot be ensured due to insufficient friction, and the screw may loosen.

[0007] The present disclosure aims to provide a vehicle-mounted device and a method for assembling the vehicle-mounted device, which can ensure the positional relationship between the vehicle-mounted device and the instrument panel while allowing the vehicle-mounted device and the vehicle mounting bracket to have the required fastening force and be fixed.

[0021] Hereinafter, the method for implementing the present disclosure (hereinafter referred to as an embodiment) is described in detail with reference to the accompanying drawings. In addition, the present disclosure is not limited to the following embodiments. In addition, the constituent elements in the following embodiments include elements that can be easily thought of by those skilled in the art, substantially the same elements, and so-called elements of the equivalent range. Furthermore, the constituent elements disclosed in the following embodiments can be appropriately combined.

[0022] The vehicle-mounted device of the embodiment is mounted in the interior of a vehicle. The vehicle-mounted device is attached to, for example, a dashboard of the vehicle.

[0023] like Figure 1 As shown, the vehicle-mounted device includes a vehicle-mounted device 1 , a vehicle mounting bracket 2 , and a cluster panel 3 .

[0024] The in-vehicle device 1 is, for example, a navigation system or an audio system with a display. The in-vehicle device 1 includes a device body 1A and a panel 1B.

[0025] The device body 1A has a housing formed in a rectangular box shape, and the housing has an upper surface 1Aa facing the upper side, a lower surface 1Ab facing the lower side, a front surface 1Ac facing the front side, a rear surface 1Ad facing the rear side, a right surface (side surface) 1Ae facing the right side, and a left surface (side surface) 1Af facing the left side. The housing of the device body 1A is a structure in which the front surface 1Ac is open and the upper surface 1Aa, the lower surface 1Ab, the rear surface 1Ad, the right surface 1Ae, and the left surface (side surface) 1Af are blocked by a metal plate. Here, in the vehicle-mounted device, the upper side, the lower side, the front side, the rear side, the right side, and the left side define each direction in a state where the vehicle-mounted device 1 is mounted in front of the driver's seat of the vehicle. That is, the side from the front of the driver's seat to the driver's seat side is set as the "front side", the side facing the windshield side of the front of the vehicle is set as the "rear side", and the right side and the left side are directions when the vehicle-mounted device 1 is viewed from the front side. When the device body 1A is mounted on the vehicle, it is arranged inside the vehicle instrument (also called the dashboard).

[0026] The device body 1A has threaded holes 1Ag formed on the left and right side surfaces 1Ae and 1Af. The threaded holes 1Ag are used to mount the vehicle mounting bracket 2 on the device body 1A. A plurality of threaded holes 1Ag (two in the embodiment) are arranged in a front-to-back arrangement on the right surface 1Ae and the left surface 1Af. All the threaded holes 1Ag are formed to have the same hole diameter.

[0027] Panel 1B is a display panel, which is formed into a plate shape with the display surface facing the front and extending in a rectangular shape in the upper, lower, left and right directions, and is arranged on the front side of the device body 1A. Panel 1B covers the front side of the device body 1A. In the present embodiment, panel 1B is larger than the device body 1A in the up-down direction and the left-right direction. The display surface of panel 1B is composed of, for example, a liquid crystal display (LCD: Liquid Crystal Display) or an organic EL (Organic Electro-Luminescence) display. The display surface can be configured as a touch panel. In addition, although not explicitly shown in the figure, panel 1B can be provided with operation buttons for performing various operations of the vehicle-mounted device 1.

[0028] The panel 1B is provided with a protruding outer peripheral surface 1Ba which is continuous in an annular shape in the vertical direction and the horizontal direction, and a rib 1Bb which is continuous in an annular shape is also formed. The rib 1Bb functions as a positioning mechanism which cooperates with the claw portion 3B of the instrument panel 3 to position the panel 1B and the instrument panel 3 relative to each other. The claw portion 3B is described in detail in the following description of the instrument panel 3.

[0029] The vehicle mounting bracket 2 is mounted on the device body 1A and mounted on the vehicle. The vehicle mounting bracket 2 includes a right vehicle mounting bracket 2A mounted on the right surface 1Ae of the device body 1A and a left vehicle mounting bracket 2B mounted on the left surface 1Af. The right vehicle mounting bracket 2A and the left vehicle mounting bracket 2B are bilaterally symmetrical structures, and the same reference numerals are attached to the same parts to explain one vehicle mounting bracket 2.

[0030] The vehicle mounting bracket 2 is made of a metal plate, such as Figures 1 to 3 As shown, there are a device side contact piece 2a, a panel side contact piece 2b and a vehicle side contact piece 2c.

[0031] The device side contact piece 2a is formed into a plate shape with the plate surface facing the side (right side, left side) so as to be abutted along the side surface (right surface 1Ae, left surface 1Af) of the device body 1A. The device side contact piece 2a is formed with a plurality of (two in the embodiment) mounting holes 2aa, 2ab arranged in the front-to-back direction corresponding to the plurality of threaded holes 1Ag arranged in the front-to-back direction on the side surfaces (right surface 1Ae, left surface 1Af) of the device body 1A. Figure 3As shown, each mounting hole 2aa, 2ab is formed to have a diameter larger than the diameter of the threaded hole 1Ag. Moreover, each mounting hole 2aa, 2ab is formed to have a larger diameter as it moves toward the rear side. Specifically, each mounting hole 2aa, 2ab is formed to have a front-rear diameter D1 larger than the diameter D0 of the threaded hole 1Ag, and the upper and lower diameters D3 are formed to be larger as they move toward the rear side relative to the upper and lower diameters D2. For example, each mounting hole 2aa, 2ab is formed relative to the threaded hole 1Ag such that D1 / D0=1.5, D2 / D0=1.8, and D3 / D0=2.

[0032] The panel side contact piece 2b is formed in a plate shape with the plate surface facing forward so as to be disposed in contact with the instrument panel 3. The panel side contact piece 2b itself contacts the protruding portion 3Ca of the instrument panel 3. In addition, the panel side contact piece 2b is formed with a screw 4 (see FIG. 1 ) formed therethrough to be screwed into the protruding portion 3Ca. Figure 7 ) is inserted through and locked in the locking hole 2ba. In addition, the panel side contact piece 2b is formed with an insertion hole 2bb through which the protrusion 3Cb of the instrument panel 3 is inserted. The protrusion 3Ca and the protrusion 3Cb of the instrument panel 3 are described in detail in the following description of the instrument panel 3.

[0033] The vehicle side contact piece 2c is formed in a plate shape with the plate surface facing downward so as to be abutted against the mounting surface on the vehicle side (not shown). The vehicle side contact piece 2c is formed with an insertion hole 2ca through which a protrusion formed protruding from the mounting surface on the vehicle side is inserted. The insertion hole 2ca is formed in a substantially rectangular shape, and is formed so that the protrusion having a rectangular outer shape can be inserted with a certain margin. In addition, the vehicle side contact piece 2c is formed with locking holes 2cb through which screws that are screwed to the mounting surface on the vehicle side are inserted and locked at the front and rear of each insertion hole 2ca.

[0034] like Figure 1 and Figure 4 As shown, the instrument panel 3 is formed in a substantially rectangular frame shape so as to surround the outer periphery of the panel 1B of the vehicle-mounted device 1. The instrument panel 3 has an inner peripheral surface 3A formed so as to follow the outer peripheral surface 1Ba of the panel 1B. That is, the panel 1B is inserted into the frame of the instrument panel 3 so that the outer peripheral surface 1Ba and the inner peripheral surface 3A face each other. The inner peripheral surface 3A is continuously formed in an annular shape in the vertical and horizontal directions. The instrument panel 3 has a claw portion 3B, a protruding portion 3Ca, and a protruding portion 3Cb.

[0035] The claw portion 3B functions as a positioning mechanism that cooperates with the rib 1Bb of the panel 1B to position the panel 1B and the instrument panel 3 relative to each other. The claw portion 3B is provided on the upper and lower inner peripheral surfaces 3A and the left and right inner peripheral surfaces 3A. In the embodiment, the claw portion 3B is provided at two locations on the upper and lower inner peripheral surfaces 3A and one location on the left and right inner peripheral surfaces 3A, for a total of six locations. The claw portion 3B is provided for the rib 1Bb of the panel 1B in the vehicle-mounted device 1 to be locked, and includes a supporting claw 3Ba and a limiting claw 3Bb. The supporting claw 3Ba is formed to protrude downward on the upper side, protrude upward on the lower side, protrude to the left on the right side, and protrude to the right on the left side. The limiting claw 3Bb is formed to protrude backwards. The panel 1B is inserted into the frame of the instrument panel 3 from the rear side. At this time, each supporting claw 3Ba abuts against the rib 1Bb of the panel 1B on the front side. Therefore, the panel 1B is restricted from moving in the forward direction by the abutment of the rib 1Bb against each supporting claw 3Ba. In addition, each restriction claw 3Bb abuts against the rib 1Bb of the panel 1B at the upper side, the lower side, the right side, and the left side. Therefore, the panel 1B is restricted from moving in the up, down, left, and right directions by the abutment of the rib 1Bb against each restriction claw 3Bb. Therefore, the panel 1B is restricted from moving forward in the up, down, left, and right directions relative to the instrument panel 3 by the claw 3B and is positioned.

[0036] The protruding portion 3Ca is formed to protrude rearward at a position further to the left and right outside of the frame formed by the inner peripheral surface 3A of the instrument panel 3. The protruding end surface of the protruding portion 3Ca abuts against the panel side abutment piece 2b of the vehicle mounting bracket 2. The protruding portion 3Ca is configured to fasten the screw 4 (see Figure 7 ). The protrusion 3Cb is formed together with the abutment 3Ca to protrude rearward at a position outside the frame formed by the inner peripheral surface 3A of the instrument panel 3. The protrusion 3Cb is inserted into the insertion hole 2bb of the panel side abutment piece 2b of the vehicle mounting bracket 2. In a state where the protrusion 3Cb is inserted into the insertion hole 2bb and the panel side abutment piece 2b abuts against the protruding end face of the abutment 3Ca, the screw 4 is fastened to the end face of the abutment 3Ca via the locking hole 2ba of the panel side abutment piece 2b, so that the vehicle mounting bracket 2 is restricted from moving in the front and rear direction relative to the instrument panel 3, and is restricted from moving in the rotation direction centered on the screw 4 by the protrusion 3Cb. Therefore, the vehicle mounting bracket 2 is positioned and fixed relative to the instrument panel 3 by the abutment 3Ca, the protrusion 3Cb, and the screw 4.

[0037] In addition, if Figure 1 and Figure 4 As shown in FIG. 1 , the instrument panel 3 has a locking protrusion 3D formed on the left and right outer sides of the frame formed by the inner peripheral surface 3A so as to protrude rearward. Although not shown in the figure, the locking protrusion 3D is inserted into and locked in a locking hole on the vehicle side.

[0038] Below, refer to Figure 5 Flowchart and Figures 6 to 10The assembly method of the vehicle-mounted device of the implementation mode is described in the assembly order.

[0039] like Figure 5 and Figure 6 As shown, the assembly method of the vehicle-mounted device of the embodiment positions the instrument panel 3 and the panel 1B in step S1. In step S1, the instrument panel 3 is placed on a flat table with the front side facing downward. In this state, the front side of the panel 1B is inserted into the frame of the instrument panel 3 from the rear side. Then, the panel 1B is positioned by restricting the movement of the panel 1B in the forward, upward, downward, leftward and rightward directions relative to the instrument panel 3 by the claws 3B.

[0040] Then, if Figure 5 and Figure 7 As shown, in step S2, the vehicle mounting bracket 2 is positioned and temporarily fixed to the instrument panel 3. In step S2, the screw 4 is fastened to the distal end surface of the protruding portion 3Ca through the locking hole 2ba in a state where the protruding portion 3Cb of the instrument panel 3 is inserted through the insertion hole 2bb of the panel side contact piece 2b in the vehicle mounting bracket 2 and the panel side contact piece 2b is contacted with the protruding distal end surface of the protruding portion 3Ca. Thus, the vehicle mounting bracket 2 is positioned and temporarily fixed relative to the instrument panel 3 by the protruding portion 3Ca, the protruding portion 3Cb and the screw 4.

[0041] Then, if Figure 5 and Figure 8 As shown, in step S3, the vehicle mounting bracket 2 is temporarily fixed to the device body 1A of the vehicle-mounted device 1. In step S3, the device side contact piece 2a of the vehicle mounting bracket 2 is made along the side surface (right surface 1Ae, left surface 1Af) of the device body 1A, and the screws 5 are fastened to the respective threaded holes 1Ag through the respective mounting holes 2aa, 2ab. Thus, the vehicle mounting bracket 2 is temporarily fixed to the device body 1A.

[0042] Here, in step S1 and step S2, the panel 1B of the vehicle-mounted device 1 and the vehicle mounting bracket 2 are positioned relative to the instrument panel 3, but due to manufacturing errors at various locations, the mounting holes 2aa and 2ab of the device-side abutment piece 2a in the vehicle mounting bracket 2 do not coincide with the threaded holes 1Ag of the device body 1A, and there is a problem that the vehicle mounting bracket 2 cannot be mounted on the device body 1A using the screws 5. In view of this problem, the vehicle-mounted device 1 is Fig. 9As shown, each mounting hole 2aa, 2ab is formed with a diameter larger than that of each threaded hole 1Ag, so that the manufacturing error can be absorbed and each mounting hole 2aa, 2ab can be made consistent with each threaded hole 1Ag. However, if the diameter of each mounting hole 2aa, 2ab is made larger than the diameter of each threaded hole 1Ag, the seat surface of the head of the screw 5 and the ground contact surface around each mounting hole 2aa, 2ab become smaller, and the required tightening force cannot be ensured due to insufficient friction, and the screw 5 may become loose. Therefore, in the vehicle-mounted device of the embodiment, each mounting hole 2aa, 2ab is formed with a small upper and lower hole diameter on the front side and a larger upper and lower hole diameter toward the rear side. In the vehicle-mounted device of the embodiment, the front panel 1B is positioned relative to the instrument panel 3, and the device-side abutment piece 2a of the vehicle mounting bracket 2 (2A, 2B) is arranged along the two side surfaces (right surface 1Ae and left surface 1Af) of the vehicle-mounted device 1, so that, as shown in FIG. Fig. 9 As shown by the middle arrow R, the tolerance caused by manufacturing errors and the like is mainly likely to occur in the form of the device body 1A tilting in the upward and downward directions, and becomes larger on the rear side. Therefore, as in the vehicle-mounted device of the embodiment, by forming each mounting hole 2aa, 2ab so that the upper and lower aperture diameters become larger toward the rear side, at least in the mounting hole 2aa on the front side, the contact surface between the surrounding area and the seat surface of the screw 5 can be larger. As a result, the vehicle-mounted device of the embodiment is not prone to insufficient friction, the required tightening force can be ensured, and the screw 5 can be prevented from loosening. In addition, in the vehicle-mounted device of the embodiment, each mounting hole 2aa, 2ab is formed so that the front and rear apertures are equal and the upper and lower apertures become larger toward the rear side. Therefore, in each mounting hole 2aa, 2ab, the front and rear apertures can be set to be equal, so that the contact surface between the surrounding area and the seat surface of the screw 5 is larger. As a result, the vehicle-mounted device of the embodiment is not prone to insufficient friction, the required tightening force can be ensured, and the screw 5 can be prevented from loosening.

[0043] Then, if Figure 5 and Fig.10 As shown, in step S4, the vehicle mounting bracket 2 is fixed to the instrument panel 3. That is, in step S4, the screw 4 is tightened to fix the vehicle mounting bracket 2 to the instrument panel 3. Next, in step S5, the vehicle mounting bracket 2 is fixed to the device body 1A. That is, in step S5, the screw 5 is tightened to fix the vehicle mounting bracket 2 to the device body 1A.

[0044] The vehicle-mounted device of the embodiment is assembled in this way, and the vehicle-mounted device can be mounted on the vehicle by screwing the vehicle-side contact piece 2 c of the vehicle mounting bracket 2 to the mounting surface on the vehicle side.

[0045] In addition, when the vehicle-mounted device is installed on the vehicle, the insertion hole 2ca of the vehicle-side abutment piece 2c can be inserted into the protrusion of the mounting surface on the vehicle side with a margin, thereby absorbing, for example, the misalignment between the vehicle-side abutment piece 2c side and the vehicle side when the locking protrusion 3D of the instrument panel 3 is locked on the vehicle side.

[0046] Thus, the vehicle-mounted device of the embodiment comprises: a vehicle-mounted device 1, in which a panel 1B is provided on the front surface of a device body 1A; an instrument panel 3, which is arranged on the panel 1B; a positioning mechanism (ribs 1Bb, claws 3B), which positions the panel 1B and the instrument panel 3 relative to each other; a vehicle mounting bracket 2, which is fixed to the instrument panel 3 and the device body 1A and mounted on the vehicle; and mounting holes 2aa, 2ab, a plurality of which are arranged in the front-to-back direction on the vehicle mounting bracket 2, and are formed to have a diameter larger than the diameter of a plurality of threaded holes 1Ag arranged in the front-to-back direction on the side surfaces (right surface 1Ae, left surface 1Af) of the device body 1A, and the upper and lower hole diameters increase toward the rear.

[0047] In the vehicle-mounted device, each mounting hole 2aa, 2ab is formed to have a larger diameter than each threaded hole 1Ag, so that the manufacturing error can be absorbed and each mounting hole 2aa, 2ab can be made consistent with each threaded hole 1Ag. In particular, in the vehicle-mounted device, each mounting hole 2aa, 2ab is formed to have a larger upper and lower hole diameter toward the rear side, so that the tolerance becomes larger at the rear side due to the inclination of the device body 1A in the vertical direction, and at least in the front side mounting hole 2aa, the contact surface between the surrounding and the seat surface of the screw 5 can be larger. As a result, according to the vehicle-mounted device of the embodiment, while ensuring the positional relationship between the vehicle-mounted device 1 and the instrument panel 3 by the positioning mechanism (rib 1Bb, claw portion 3B), the vehicle-mounted device 1 and the vehicle mounting bracket 2 can be fixed with the required fastening force.

[0048] In the vehicle-mounted device of the embodiment, each of the mounting holes 2aa and 2ab is formed so that the front and rear hole diameters are equal and the upper and lower hole diameters increase toward the rear side.

[0049] According to this vehicle-mounted device, by setting the front and rear hole diameters of the mounting holes 2aa and 2ab to be equal, the contact surface around the mounting holes 2aa and 2ab can be increased with the seat surface of the screw 5. As a result, the vehicle-mounted device of the embodiment can ensure the required fastening force.

[0050] In addition, in the vehicle-mounted device of the embodiment, the positioning mechanism includes: a claw portion 3B formed in the up, down, left, and right directions within the frame of the instrument panel 3; and a rib 1Bb formed on the outer periphery of the panel 1B in a manner that engages with the claw portion 3B and limits the panel 1B in the front up, down, left, and right directions relative to the instrument panel 3.

[0051] According to the vehicle-mounted device, by limiting the vehicle-mounted device 1 and the instrument panel 3 in the front up, down, left and right directions, the positional relationship between the vehicle-mounted device 1 and the instrument panel 3 can be set so that the device body 1A is tilted in the up and down direction in order to obtain the above-mentioned effect of each mounting hole 2aa, 2ab.

[0052] In addition, in the vehicle-mounted device of the embodiment, the vehicle mounting bracket 2 has: a panel side abutment piece 2b, which abuts and is fixed to a protruding portion 3Ca formed on the rear surface of the instrument panel 3; and an insertion hole 2bb, which is provided on the panel side abutment piece 2b, for inserting a protruding portion 3Cb formed on the rear surface of the instrument panel 3.

[0053] According to this vehicle-mounted device, the vehicle mounting bracket 2 can be aligned and fixed to the rear surface of the instrument panel 3, and the positional relationship between the vehicle mounting bracket 2 and the instrument panel 3 can be set to obtain the above-mentioned effects of the mounting holes 2aa and 2ab.

[0054] The assembly method of the vehicle-mounted device of the embodiment includes the following steps: positioning the instrument panel 3 and the panel 1B by means of a positioning mechanism (rib 1Bb, claw portion 3B); fixing the vehicle mounting bracket 2 to the instrument panel 3; and fixing the vehicle mounting bracket 2 to the device body 1A by screwing a screw 5 into the threaded hole 1Ag via the mounting holes 2aa and 2ab.

[0055] According to the vehicle-mounted device assembling method, the positional relationship between the vehicle-mounted device 1 and the instrument panel 3 can be ensured by the positioning mechanism (rib 1Bb, claw portion 3B), and the vehicle-mounted device 1 and the vehicle mounting bracket 2 can be fixed with a required fastening force.
