This international application claims priority based on Japanese Patent Application No. 2020-088934 filed with the Japan Patent Office on May 21, 2020, and Japanese Patent Application No. 2020-088934. The entire contents are incorporated in this international application by reference.

This disclosure relates to an in-vehicle device.

For example, regarding ETC on-board equipment, it is being considered to sell it to general customers in a state where it is installed as standard on the vehicle, and it is already in operation. Such an ETC on-board unit may be required to have a protective function for suppressing unauthorized use due to theft. This protection function includes, for example, a function to prevent the information recorded in the ETC on-board unit from being stolen when the ETC on-board unit is removed from the vehicle or disassembled.

Patent Document 1 discloses an ETC on-board unit having a protection function. The ETC on-board unit disclosed in Patent Document 1 is attached to the windshield of a vehicle by a double-sided adhesive tape. This ETC on-board unit includes a switch operation button provided so as to protrude from the surface to which the double-sided adhesive tape is adhered in the ETC on-board unit. This switch operation button is urged from the inside to the outside of the ETC on-board unit by an elastic member, and is projected from the ETC on-board unit by this urging force. When this ETC on-board unit is attached to the windshield, the switch operation button comes into contact with the windshield, receives a load from the windshield, and is pushed into the inside of the ETC on-board unit. This enables the protection function. When the ETC on-board unit is removed from the vehicle or disassembled, the switch operation button is brought out from the ETC on-board unit by the urging force of the elastic member, and the protection function is activated.

Chinese Patent No. 105620377

As a result of detailed examination by the inventor, the following problems have been found in the ETC on-board unit disclosed in Patent Document 1. That is, when the ETC on-board unit disclosed in Patent Document 1 is mounted on a vehicle as standard equipment, it is necessary for the vehicle manufacturer to strongly press the ETC on-board unit against the windshield and attach it with double-sided adhesive tape. At this time, a large load is applied to the windshield in the direction perpendicular to the glass surface. Therefore, if the windshield is already attached to a part such as an instrument panel or a vehicle body with an adhesive, the bond between the windshield and the part may be peeled off.

In order to prevent this, it is conceivable to attach the ETC on-board unit to the windshield as follows, for example. That is, a bracket is provided in advance on the surface of the windshield. Then, the ETC on-board unit is attached to the bracket by sliding it in a direction parallel to the surface of the windshield. The switch operation button is pushed into the ETC on-board unit by the load from the windshield or the bracket as described above.

However, while such a mounting method can reduce the load on the windshield, another problem arises. That is, since the ETC on-board unit is slid in a direction parallel to the surface of the windshield, a load in the slide direction is applied to the switch operation button from the windshield or the bracket. The slide direction load is a load in a direction intersecting the direction in which the switch operation button protrudes from the ETC on-board unit or is pushed inward. When a load in the slide direction is applied to the switch operation button, the switch operation button is tilted, which may prevent the protection function from being normally activated even if the ETC on-board unit is attached to the bracket.

Such a problem is not limited to the ETC on-board unit, and is configured so that the switch is operated when it is normally attached to the vehicle, and the operation of the switch is released when it is removed from the vehicle or disassembled. In addition, it is a problem that can occur in various in-vehicle devices as well.

One aspect of the present disclosure is that in an in-vehicle device provided with a switch, the switch is properly operated after being attached to the attachment target while suppressing the load applied to the attachment target when the in-vehicle device is attached to the attachment target of the vehicle. It is preferable to be able to provide a technique that can be used.
An in-vehicle device according to one aspect of the present disclosure includes a case, a mounting portion, a switch, and an operating member. The mounting portion is mounted on the bracket. The bracket is provided on the mounting surface of the vehicle. The mounting portion is mounted on the bracket by sliding in a direction non-perpendicular to the mounting surface with respect to the bracket. The switch is housed in a case. The operating member is housed in a case. The operating member is configured to be able to move from the first position to the second position relative to the case. The operating member puts the switch in the first operating state at the first position. The operating member puts the switch in the second operating state in response to the operation member being moved from the first position to the second position.

According to such a configuration, when the in-vehicle device is mounted on the mounting surface of the vehicle, the switch can be properly put into the second operating state after mounting on the mounting surface while suppressing the load applied to the mounting surface. It will be possible.

The fitted portions 211,212 and 213,214 are provided with recesses 211a, 212a, 213a and 214a, respectively. As will be described later, fitting portions 41, 42, 43, 44 in the in-vehicle device 1 are fitted into the recesses 211a, 212a, 213a, and 214a (see FIGS. 4, 9 and the like).

The mounting bracket 210 is further provided with two bracket engaged portions 216 and 217. The bracket engaged portions 216 and 217 are provided so as to face each other along the X axis at positions slightly deviated from the fitted portions 212 and 214 in the positive direction of the Y axis. As will be described later, the inner engaging portions 24, 25 (see FIGS. 4, 5 and the like) in the in-vehicle device 1 are engaged with the bracket engaged portions 216 and 217.

The windshield 200 is mounted on the vehicle 300 with the glass surface tilted. Specifically, the windshield 200 may be mounted so that the X-axis is parallel to the horizontal plane, for example. Further, for example, in the front glass 200, the Y-axis is non-parallel in both the horizontal direction and the vertical direction, and the negative direction of the Y-axis is toward the road surface and the positive direction of the Y-axis is away from the road surface. It may be installed.

The vehicle-mounted device 1 of the present embodiment may be, for example, a so-called ETC vehicle-mounted device for using ETC and ETC 2.0. By communicating with the roadside communication device provided in the vicinity of the traveling path of the vehicle 300, the user of the vehicle 300 can enjoy the services of ETC and ETC 2.0.

A specific configuration of the in-vehicle device 1 will be described with reference to FIGS. 1 to 12. As shown in FIGS. 1, 6 and 7, the in-vehicle device 1 includes a case 30 and an outer base 70. As shown in FIGS. 5 to 7, the in-vehicle device 1 further includes a removal detection switch 16.

The case 30 has a substantially rectangular parallelepiped shape. The case 30 opens in the negative direction of the Z axis (hereinafter referred to as “downward”) and in the positive direction of the Y axis, and partially opens in the negative direction of the Y axis. The case 30 includes a case bottom plate 31, a first side plate 32, a second side plate 33, and a storage space 34. The accommodation space 34 is a space surrounded by the case bottom plate 31, the first side plate 32, and the second side plate 33. The accommodation space 34 accommodates almost all the components constituting the vehicle-mounted device 1, including the outer base 70 and the removal detection switch 16.

The case bottom plate 31 is provided with a case opening 35. As shown in FIGS. 1 to 3, 6 and 7, the in-vehicle device 1 includes a communication switch operation unit 5. The communication switch operation unit 5 is arranged so that almost the entire surface on the Z-axis positive direction (hereinafter referred to as “upper”) side is exposed from the case opening 35 and closes the case opening 35. NS. The communication switch operation unit 5 is, for example, pushed by the user of the in-vehicle device 1.

The case bottom plate 31 is further provided with two lens fitting holes 36 and 37. The indicator lens 7 shown in FIG. 7 is fitted into the lens fitting holes 36 and 37.

The in-vehicle device 1 of the present embodiment has the same protection function as the above-mentioned protection function. That is, when the vehicle-mounted device 1 is disassembled or destroyed, at least a part or all of the functions of the vehicle-mounted device 1 are forcibly stopped so that the information recorded in the vehicle-mounted device 1 is not stolen.

More specifically, in the present embodiment, the protection function is enabled by turning on the removal detection switch 16, for example. Then, when the removal detection switch 16 is turned off, for example, while the protection function is enabled, the protection function is activated. When the protection function is activated, a part or all of the functions of the in-vehicle device 1 are forcibly stopped.

The removal detection switch 16 is turned on when the movable piece is displaced by receiving a load in the positive direction of the Y axis. Specifically, the removal detection switch 16 of the present embodiment includes a movable piece configured to be rotatable around a rotation axis. When no other object is in contact with the movable piece, the movable piece is opened by the urging force of an elastic member (not shown). FIGS. 5 to 7 and 12 show the removal detection switch 16 in which the movable piece is in the open state. When the movable piece is in the open state, the removal detection switch 16 is turned off.

When the movable piece receives a load in the positive direction of the Y-axis, it rotates toward the second substrate 11 (that is, upward) against the urging force. When the movable piece rotates by a certain angle or more, the removal detection switch 16 is turned on. FIG. 24, which will be described later, shows a state in which the movable piece is rotated by a certain angle or more from the open state and the removal detection switch 16 is turned on.

The outer base 70 will be described with reference to FIGS. 4, 6 to 8. The outer base 70 has a substantially rectangular parallelepiped shape that opens upward. The outer base 70 is arranged so as to cover the inner base 20 described later from below.

In the present embodiment, the inner base 20 is fixed to the case 30, while the outer base 70 is temporarily fixed or finally fixed to the case 30. Specifically, the outer base 70 is temporarily fixed to the case 30 before the vehicle-mounted device 1 is attached to the vehicle 300. That is, the in-vehicle device 1 is delivered to the vehicle manufacturer with the outer base 70 temporarily fixed. FIGS. 1 to 4 and 6 show a state in which the outer base 70 is temporarily fixed to the case 30. When the outer base 70 is temporarily fixed, one end of the outer base 70 protrudes from the case 30.

When the in-vehicle device 1 is attached to the vehicle 300 in the manufacturing process of the vehicle 300 by the vehicle manufacturer, the outer base 70 is actually fixed to the case 30. The displacement from temporary fixing to final fixing will be described in detail later. To put it simply, by pushing the outer base 70 into the case 30 (that is, sliding it in the positive direction of the Y axis) from the temporarily fixed state, the entire outer base 70 is a case as shown in FIG. It can be said that it is to be housed in 30.

The outer base 70 has a bottom surface 71. Two outer openings 72 and 73 are provided on the bottom surface 71. As shown in FIG. 4, the outer opening 72 exposes the inner engaging portion 24 described later in the inner base 20 downward. The outer opening 73 exposes the inner engaging portion 25 described later in the inner base 20 downward.

The bottom surface 71 is further provided with a switch contact portion 74 as shown in FIGS. 6 and 8. The switch contact portion 74 has a low-profile convex shape that is erected upward from the bottom surface 71. As will be described later, the switch contact portion 74 abuts on the movable piece of the removal detection switch 16 in response to the displacement of the outer base 70 from the temporarily fixed state to the main fixed state, and the switch contact portion 74 abuts on the movable piece in the Y-axis positive direction. Gives the load of. As a result, the movable piece rotates, and the removal detection switch 16 is turned on.

After the removal detection switch 16 is turned on by this fixing, when the switch contact portion 74 is separated from the removal detection switch 16 due to, for example, disassembly or destruction of the in-vehicle device 1, the removal detection switch 16 is movable. The piece becomes open. When the movable piece is in the open state, the removal detection switch 16 is turned off and the protection function is activated.

The outer base 70 further includes two outer engaging portions 75, 76 as shown in FIGS. 1, 2, 7, and 8. The outer engaging portions 75 and 76 are plate-shaped members extending from the side wall on the negative direction side of the Y axis in the outer base 70, and an engaging piece is formed on the tip end side. The outer engaging portions 75 and 76 are elastically movable in the X-axis direction. As will be described later with reference to FIGS. 22 and 23, the outer engaging portions 75 and 76 position the outer base 70 in a temporarily fixed or fully fixed state with respect to the case 30.

The outer base 70 further includes two first base ribs 77 and 78, as shown in FIGS. 4 and 8. In FIG. 25 showing a cross section of XXV-XXV in FIG. 8, the first base rib 77 and the above-mentioned switch contact portion 74 are shown.

The outer base 70 further includes a second base rib 79 as shown in FIGS. 1 to 3, 7, and 8. Note that FIG. 26, which shows a cross section of XXVI-XXVI in FIG. 8, shows a second base rib 79.

The first base ribs 77 and 78 and the second base rib 79 are used to further strengthen the engagement of the outer base 70 with the case 30, as will be described later with reference to FIGS. 29 to 32.

The outer base 70 further includes two hooks 80, 81, as shown in FIGS. 4, 7, and 8. The hook 80 is provided on the side surface of the outer base 70 on the positive direction side of the X axis. The hook 81 is provided on the side surface of the outer base 70 on the negative direction side of the X axis. The hooks 80 and 81 are used to prevent the first side plate 32 and the second side plate 33 of the case 30 from opening outward, as will be described later with reference to FIGS. 22 and 23.

As shown in FIGS. 6 and 7, the in-vehicle device 1 further includes a first substrate 10. As shown in FIGS. 5 to 7, the in-vehicle device 1 further includes a second substrate 11. As shown in FIGS. 7 and 12, the first substrate 10 and the second substrate 11 are provided so that the plate surfaces are parallel to the XY plane and face each other in the Z-axis direction. The upper surface (that is, the upper surface) of the first substrate 10 faces the case bottom plate 31.

The first board 10 and the second board 11 are electrically connected to each other. Various circuits and components are mounted on the first board 10 and the second board 11, respectively. With these various circuits and parts, the function as an ETC on-board unit is realized.

The various circuits and parts include the above-mentioned removal detection switch 16. As shown in FIGS. 5 to 7 and 12, the removal detection switch 16 is provided on the lower surface (that is, the lower surface) of the second substrate 11.

Further, the various circuits and parts include the connector 12. The connector 12 is electrically connected to the first board 10 and the second board 11. The in-vehicle device 1 is electrically connected to the vehicle 300 via the connector 12.

Further, as shown in FIGS. 6, 7, 11, 12, etc., various circuits and parts include a communication switch 13 and two LEDs 14, 15. The communication switch 13 and the two LEDs 14 and 15 are mounted on the upper surface of the first substrate 10.

The communication switch 13 is turned on via the communication switch operation unit 5. The vehicle-mounted device 1 of the present embodiment has, for example, a wireless communication function based on a communication standard of Bluetooth (Bluetooth is a registered trademark). The communication switch 13 receives, for example, an instruction from the user to execute pairing in Bluetooth. When the communication switch 13 is turned on, the in-vehicle device 1 performs pairing with another communication device.

The in-vehicle device 1 individually emits light of LEDs 14 and 15 according to the state of the in-vehicle device 1 or the communication status. The light emitted from the LEDs 14 and 15 is incident on the indicator lens 7. The light incident on the indicator lens 7 is guided through the inside of the indicator lens 7 and radiated to the outside of the in-vehicle device 1 from the design surface of the indicator lens 7, that is, the surface exposed to the lens fitting holes 36 and 37.

As shown in FIGS. 6 and 7, the first substrate 10 is provided with a notch 17. As shown in FIG. 6, the boss 58 in the case 30 is inserted into the notch 17. As shown in FIGS. 6 and 7, the second substrate 11 is provided with a screw through hole 18.

As shown in FIGS. 5 to 7, the in-vehicle device 1 further includes an inner base 20. The inner base 20 has a substantially rectangular parallelepiped shape that opens upward. The inner base 20 is arranged so as to be inserted into the outer base 70 from above. That is, the inner base 20 is partially housed in the outer base 70.

As shown in FIG. 7, the inner base 20 includes a substrate accommodating space 21. The first substrate 10 and the second substrate 11 are accommodated in the substrate accommodating space 21 as shown in FIGS. 11 and 12.

As shown in FIGS. 5 to 7, a first inner opening 22 and a second inner opening 23 are provided on the bottom surface of the inner base 20. The removal detection switch 16 projects to the outside of the inner base 20 via the first inner opening 22.

The inner base 20 further includes two inner engaging portions 24 and 25 as shown in FIGS. 4 to 6. As described above, the inner engaging portions 24 and 25 are exposed downward from the outer openings 72 and 73 in the outer base 70 (see FIG. 4). As will be described later with reference to FIGS. 20 and 21, when the in-vehicle device 1 is attached to the mounting bracket 210, the inner engaging portions 24 and 25 are engaged with the bracket engaged portions 216 and 217.

The second board 11 provided with the removal detection switch 16 is housed in the inner base 20. The removal detection switch 16 projects from the first inner opening 22 of the inner base 20. However, the inner base 20 including the removal detection switch 16 is covered from below by the outer base 70. Therefore, the removal detection switch 16 is covered by the base bottom surface 71.

That is, the removal detection switch 16 is covered by the base bottom surface 71 in both the temporarily fixed state and the main fixed state of the outer base 70, and is not exposed to the outside of the in-vehicle device 1. Therefore, when the in-vehicle device 1 is transported to the vehicle manufacturer, or after the in-vehicle device 1 is delivered to the vehicle manufacturer until it is actually attached to the vehicle 300, it is removed from unintended interference, contact, dust, dust, or the like. The detection switch 16 is protected.

As described above, the outer base 70 has not only the function of turning on the removal detection switch 16 but also the function of protecting the removal detection switch 16 from external interference. Therefore, it is possible to prevent the removal detection switch 16 from being erroneously turned on due to interference from the outside of the in-vehicle device 1.

When the outer base 70 is temporarily fixed, the outer engaging portions 75, 76 of the outer base 70 are engaged with the first engaged portions 45, 47. When the outer base 70 is in the main fixed state, the outer engaging portions 75, 76 are engaged with the second engaged portions 46, 48.

The case 30 further includes two first case slits 39 and 40 and a second case slit 38a, as shown in FIGS. 9 and 10. The second case slit 38a is formed by opening the slit base 38. The slit base 38 is provided so as to extend in the negative direction of the Z axis from the side surface of the case 30 on the negative direction side of the Y axis.

Note that FIG. 27 showing a cross section of XXVII-XXVII in FIG. 10 shows a first case slit 39. Further, FIG. 28 showing a cross section of XXVIII-XXVIII in FIG. 10 shows a first case slit 40 and a second case slit 38a. As will be described later, the first base ribs 77 and 78 in the outer base 70 are inserted into the first case slits 39 and 40. The second base rib 79 in the outer base 70 is inserted into the second case slit 38a.

The case 30 is further provided with a boss 58. The boss 58 has, for example, a columnar shape. The boss 58 is formed with a screw hole. A screw 90 is screwed into the screw hole of the boss 58. More specifically, as shown in FIGS. 5 and 6, the screw 90 penetrates a screw through hole (not shown) provided on the bottom surface of the inner base 20 and a screw through hole 18 of the second substrate 11. It is screwed into the boss 58. When the screw 90 is screwed into the boss 58, the bottom surface of the inner base 20 and the second substrate 11 are sandwiched between the boss 58 and the head of the screw 90. That is, the assembly including the inner base 20, the first substrate 10, and the second substrate 11 is fixed to the case 30 by the screws 90.

In the in-vehicle device 1 of the present embodiment configured as described above, the case bottom plate 31, the first substrate 10, the second substrate 11, and the base bottom surface 71 of the outer base 70 are parallel to each other, and all of them are in-vehicle. When the device 1 is attached to the attachment bracket 210, it is parallel to the windshield 200. The slide direction when the outer base 70 is slid from the temporarily fixed state to the main fixed state while the in-vehicle device 1 is attached to the mounting bracket 210, that is, the Y-axis positive direction is the case bottom plate 31 and the first substrate 10. , The direction parallel to the second substrate 11 and the windshield 200.

(2) Procedure for Attaching the Vehicle-mounted Device Next, a procedure for mounting the vehicle-mounted device 1 on the mounting bracket 210 will be described with reference to FIGS. 13 to 24. In FIGS. 13, 14, 16 and 18, for convenience of explanation, the case 30 is shown by a broken line, and the inside of the case 30 which cannot be visually recognized by the case 30 is shown.

First, an in-vehicle device 1 in a temporarily fixed state, that is, an in-vehicle device 1 in a state in which the outer base 70 is temporarily fixed to the case 30 is prepared. Then, the relative positional relationship between the in-vehicle device 1 and the mounting bracket 210 is set to the first state shown in FIG.

In the temporarily fixed state, as shown in FIG. 22, the outer engaging portion 75 of the outer base 70 is engaged with the first engaged portion 45 of the case 30, and the outer engaging portion 76 of the outer base 70 is the case 30. It is engaged with the first engaged portion 47.

From the first state, the in-vehicle device 1 is moved downward and mounted on the mounting bracket 210. As a result, the vehicle-mounted device 1 and the mounting bracket 210 transition to the second state shown in FIGS. 14 and 15. In the second state, the fitted portions 211 to 214 of the mounting bracket 210 are covered with the case 30. Then, each of the fitting portions 41 to 44 of the case 30 is adjacent to the corresponding one of the fitted portions 211 to 214 in the mounting bracket 210 in the negative direction on the Y axis.

In the second state, as shown in FIG. 20, the inner engaging portion 24 of the inner base 20 is not yet engaged with the bracket engaged portion 216 of the mounting bracket 210. Although not shown in FIG. 20, the inner engaging portion 25 is also not yet engaged with the bracket engaged portion 217. Further, as shown in FIG. 20, the switch contact portion 74 of the outer base 70 is not in contact with the removal detection switch 16. Therefore, the removal detection switch 16 is turned off.

When the in-vehicle device 1 is slid in the positive direction of the Y axis from the second state, it transitions to the third state as shown in FIGS. 16 and 17. In the third state, each of the fitting portions 41 to 44 of the case 30 is fitted to the corresponding one of the fitted portions 211 to 214 in the mounting bracket 210. That is, the fitting portion 41 is fitted into the recess 211a of the fitted portion 211, the fitting portion 42 is fitted into the recess 212a of the fitted portion 212, and the fitting portion 43 is the recess of the fitted portion 213. It fits into 213a, and the fitting portion 44 fits into the recess 214a of the fitted portion 214.

Further, as shown in FIG. 21, the inner engaging portion 24 of the inner base 20 is engaged with the bracket engaged portion 216 of the mounting bracket 210. Although not shown in FIG. 21, the inner engaging portion 25 is similarly engaged with the bracket engaged portion 217. As shown in FIG. 21, the switch contact portion 74 of the outer base 70 is not in contact with the removal detection switch 16 even in the third state. Therefore, the removal detection switch 16 is turned off.

From the third state, push the outer base 70 in the positive direction of the Y axis so that the outer base 70 is finally fixed to the case 30. As a result, the outer base 70 is slid into the case 30 along the slide rails 61 to 64, and is in the final fixed state shown in FIGS. 18 and 19.

Specifically, when the outer base 70 is slid from the third state, the outer engaging portions 75 and 76 come into contact with the second engaged portions 46 and 48. In this state, the outer base 70 is still in the temporarily fixed state, and the removal detection switch 16 is kept off. When the outer base 70 is further pushed in from this state, the outer base 70 is elastically deformed into the inside of the outer base 70 by receiving the reaction force from the second engaged portions 46 and 48, and the outer base 70 is moved. I will slide. Then, the outer engaging portions 75 and 76 get over the second engaged portions 46 and 48 and engage with the second engaged portions 46 and 48 as shown in FIG. 23. As a result, the outer base 70 is in a fixed state.

Further, in the process of transitioning from the temporary fixing to the main fixing of the outer base 70, the switch contact portion 74 of the outer base 70 comes into contact with the removal detection switch 16. Then, in the final fixed state, as shown in FIG. 24, the movable piece of the removal detection switch 16 is rotated by the switch contact portion 74, and the removal detection switch 16 is turned on.

The removal detection switch 16 may be turned on at any timing after the outer engaging portions 75, 76 come into contact with the second engaged portions 46, 48 in the temporarily fixed state. For example, the removal detection switch 16 may be turned on by the outer engaging portions 75, 76 getting over the second engaged portions 46, 48. Further, for example, the outer engaging portions 75, 76 may be turned on in the middle of contacting the second engaged portions 46, 48 and getting over the second engaged portions 46, 48.

Further, when the outer base 70 is finally fixed, the hooks 80 and 81 of the outer base 70 are inserted into the insertion holes 52a and 55a of the case 30 as shown in FIG. 23. This prevents the first side plate 32 and the second side plate 33 of the case 30 from opening outward.

As described above, in the present embodiment, the in-vehicle device 1 is in a state where the outer base 70 is temporarily fixed, that is, the outer engaging portion, at the stage where the in-vehicle device 1 is delivered to the vehicle manufacturer, that is, before it is mounted on the vehicle 300. The 75 and 76 are delivered in a state where they have passed over the first engaged portions 45 and 47 (see FIG. 22). Then, when the in-vehicle device 1 is mounted on the vehicle 300, the outer base 70 is slid to be in the fixed state shown in FIG. 23.

(3) Holding the outer base between the cases As described above, the outer base 70 is provided with two first base ribs 77, 78 and a second base rib 79 (see FIGS. 8, 25, 26, etc.). Further, the case 30 is provided with two first case slits 39, 40 and a second case slit 38a (see FIGS. 9, 10, 27, 28, etc.).

In the temporarily fixed state, the first base ribs 77 and 78 are not fitted into the first case slits 39 and 40 as shown in FIG. 29. Further, in the temporarily fixed state, the second base rib 79 is not fitted into the second case slit 38a as shown in FIG. 31.

On the other hand, when the fixed state is set, the first base ribs 77 and 78 are fitted into the first case slits 39 and 40 as shown in FIG. More specifically, the first base rib 77 is fitted into the first case slit 39, and the first base rib 78 is fitted into the first case slit 40. Further, in this fixed state, the second base rib 79 is fitted into the second case slit 38a as shown in FIG. 32.

Thereby, the outer base 70 is more appropriately sandwiched with respect to the case 30 in the main fixed state. In particular, the movement of the outer base 70 in the positive Y-axis direction, the movement in the X-axis direction, and the movement in the Z-axis direction are more appropriately regulated.

(4) Positioning of the First Board and the Second Board on the Case As described above, the case 30 has two first case ribs 52, 55 and four second case ribs 51, 53, 54, 56. A three-case rib 57 is provided (see FIGS. 9, 10, 27, 28, etc.).

As shown in FIGS. 29 and 30, the second substrate 11 abuts on the third case rib 57. As shown in FIGS. 24 and 33, the first substrate 10 abuts on the two first case ribs 52, 55 and the four second case ribs 51, 53, 54, 56.

As described above, the inner base 20, the first substrate 10 and the second substrate 11 are fixed to the case 30 by the screws 90. At this time, the second substrate 11 abuts on the third case rib 57, and the first substrate 10 abuts on a total of six ribs 51 to 56. Therefore, the inner base 20, the first substrate 10, and the second substrate 11 are appropriately fixed and positioned by the case 30 as compared with the fixing with only the screws 90.

(5) Effect of Embodiment According to the embodiment described above, the following effects are obtained.

The in-vehicle device 1 of the present embodiment can be mounted by sliding the case 30 with respect to the mounting bracket 210. On the other hand, the removal detection switch 16 is not turned on when the in-vehicle device 1 is attached to the attachment bracket 210. The removal detection switch 16 is turned on in response to the movement of the outer base 70 from the temporarily fixed state to the main fixed state.

Therefore, when the in-vehicle device 1 is attached to the mounting bracket 210, the removal detection switch 16 can be properly turned on after the mounting to the mounting bracket 210 while suppressing the load applied to the windshield 200.

The outer base 70 is temporarily held in a temporarily fixed state by engaging the outer engaging portions 75 and 76 with the first engaged portions 45 and 47 of the case 30. Moreover, the engagement between the outer engaging portions 75 and 76 and the first engaged portions 45 and 47 of the case 30 prevents the temporarily fixed outer base 70 from being unintentionally disengaged from the case 30. ..

The outer base 70 in the temporarily fixed state is held in the main fixed state by sliding and engaging the outer engaging portions 75 and 76 with the second engaged portions 46 and 48. Moreover, due to the engagement between the outer engaging portions 75 and 76 and the second engaged portions 46 and 48 of the case 30, the outer base 70 in the main fixed state unintentionally moves in the direction of temporary fixing. As a result, it is suppressed that the removal detection switch 16 is turned off due to the movement.

When the outer base 70 shifts from the temporarily fixed state to the main fixed state, the moving direction of the outer base 70 is restricted. That is, the outer base 70 slides substantially linearly along the slide rails 61 to 64 provided on the case 30. Therefore, the outer base 70 can be more appropriately brought into the final fixed state, and the removal detection switch 16 can be appropriately turned on by the switch contact portion 74 of the outer base 70.

The outer base 70 includes a switch contact portion 74. The removal detection switch 16 receives a load in the direction in which the outer base 70 is slid, so that the movable piece is operated and turned on. Therefore, the removal detection switch 16 can be stably turned on.

When mounting the case 30 to the mounting bracket 210, for example, simply fitting the fitting portions 41 to 44 of the case 30 to the fitted portions 211 to 214 of the mounting bracket 210 causes the vehicle-mounted device 1 to be fitted by the weight of the vehicle-mounted device 1. May move in the opposite direction of the mounting direction. If the in-vehicle device 1 moves in the opposite direction, the fitting portions 41 to 44 may be disengaged from the fitting portions 211 to 214.

On the other hand, in the present embodiment, when the case 30 is mounted on the mounting bracket 210, the inner engaging portions 24 and 25 of the inner base 20 are engaged with the bracket engaged portions 216 and 217 of the mounting bracket 210 ( See FIG. 21). This prevents the vehicle-mounted device 1 from coming off the mounting bracket 210.

When the outer base 70 is finally fixed, the hooks 80 and 81 of the outer base 70 are inserted into the insertion holes 52a and 55a of the case 30 as shown in FIG. 23. This prevents the first side plate 32 and the second side plate 33 of the case 30 from opening outward. That is, for example, even if an external force in the direction of opening outward is applied to the first side plate 32, the hook 80 regulates that the first side plate 32 is deformed in the direction of the external force. As a result, the fitting portions 41 to 44 of the case 30 and the fitted portions 211 to 214 of the mounting bracket 210 are properly maintained.
