[0012] The mounting portion 30 is used to fix the first electronic device 10 in a positional relationship that sandwiches the vehicle roof 90 at the upper part. Also, the mounting portion 30 is used to fix the second electronic device 50 at the lower part.

[0013] The second electronic device 50 sends the signal transmitted from the first electronic device 10 to the outside to the first electronic device 10. Also, the second electronic device 50 processes the signal received by the first electronic device 10. Also, the second electronic device 50 performs signal transmission and reception with a gateway ECU (not shown) of the vehicle via a cable (not shown) of an in-vehicle LAN (Local Area Network).

[0014] To explain the directions, the front-rear direction of the vehicle to which the in-vehicle device 1 is attached is defined as the x direction, the left-right direction perpendicular to the x direction is defined as the y direction, and the substantially vertical direction perpendicular to the x direction and the y direction is defined as the z direction. In FIGS. 1 to 29, the directions indicated by the respective arrows of the xyz axes are defined as the forward direction, the right direction, and the upward direction, respectively. In FIG. 2, members (such as the antenna element 15 and the first substrate 17) that are housed inside the antenna case 11 of the first electronic device 10 and are not visible from the outside, and members (the second substrate 53) that are housed inside the housing 51 of the second electronic device 50 and are not visible from the outside are shown by dotted lines. Also, in FIGS. 4, 5, 10, and 20 to 29, the illustration of the vehicle roof 90 is omitted. Further, in FIGS. 5 to 10, in order to explain the mounting structure, the illustration of some components is omitted. In the description of the claims, the z direction corresponds to the first direction, one of the x direction and the y direction corresponds to the second direction, the other of the x direction and the y direction corresponds to the third direction, and the second temporary fixing claw 52c and the claw receiving portion 33c1 correspond to the temporary fixing portion.

[0015] (First mounting structure, second mounting structure) The first electronic device 10 and the mounting portion 30 are attached via the first mounting structure, and the mounting portion 30 and the second electronic device 50 are attached via the second mounting structure. The first mounting structure includes a mechanism for sliding in a direction perpendicular to the z direction of at least one of the first electronic device 10 and the mounting portion 30 and moving in the z direction after the sliding. As the first mounting structure, the first electronic device 10 has at least the first guide 19a and the first temporary fixing claw 19b, and the mounting portion 30 has at least the first hole 31a1 and the first guide receiving portion 32b. The second mounting structure includes a mechanism for sliding in a direction perpendicular to the z direction of at least one of the mounting portion 30 and the second electronic device 50 and moving in the z direction after the sliding. As the second mounting structure, the mounting portion 30 has at least the second guide 32c and the claw receiving portion 33c1, and the second electronic device 50 has at least the second guide receiving portion 52b and the second temporary fixing claw 52c.

[0016] (Configuration of the first electronic device 10) Next, each part of the first electronic device 10 will be described.

[0017] (Antenna case 11) The antenna case 11 is made of a synthetic resin having radio wave permeability. The antenna case 11 has a shark fin shape that is inclined such that the front in the x direction is lower than the rear in the x direction, and both side surfaces are curved inward. The lower surface of the antenna case 11 is open, and a base 19 is attached to the opening of the lower surface. An antenna element 15 and a first substrate 17 are housed in the space formed by the antenna case 11 and the base 19.

[0018] (Pad 13) The pad 13 is an elastic member formed of an elastomer, rubber, or the like. The lower end peripheral portion of the antenna case 11 is attached to the upper portion of the pad 13. The pad 13 closes the gap between the lower end peripheral portion of the antenna case 11 and the peripheral portion of the base 19.

[0019] (Antenna element 15) The antenna element 15 transmits and receives electrical signals. For example, as the antenna element 15, a planar antenna for receiving satellite broadcasts, a planar antenna for receiving position information (time information) from satellites such as GPS, an antenna including a capacitive loading element and a coil for receiving AM / FM broadcasts, an antenna for V2X (vehicle-to-vehicle and vehicle-to-roadside communication), and an antenna for a communication terminal can be considered. The antenna element 15 is held by the base 19 via the first substrate 17 or the like. However, the antenna element 15 may be held directly by the base 19 without passing through the first substrate 17, or may be held on the inner wall of the antenna case 11. The antenna element 15 may be held by a holder attached to the base 19 or the like.

[0020] (First substrate 17) The first substrate 17 mounts electronic components related to the antenna element, such as an amplifier circuit and a tuning circuit, and the antenna element 15, and is held by the base 19. A first connector 21 is attached to the first substrate 17, and the first substrate 17 and the first connector 21 are electrically connected.

[0021] (Base 19) The base 19 is, for example, an antenna base, which is covered from above in the z direction by the antenna case 11 to form an accommodation space for accommodating the antenna element 15 and the like. A first substrate 17 is attached to the upper part of the base 19.

[0022] (First guide 19a) As shown in FIGS. 3 to 6, the base 19 has a first guide 19a protruding downward in the z direction. The first guide 19a is used for attaching the first electronic device 10 and the attachment portion 30. The first guide 19a is formed in a wall shape substantially perpendicular to the y direction. Three first guides 19a are provided on each of the right side and the left side in the y direction.

[0023] (First clamped portion 19a1) A first clamped portion 19a1 protruding in the y direction is provided at the lower part of the first guide 19a. Specifically, a first clamped portion 19a1 protruding rightward in the y direction is provided at the lower part of the first guide 19a on the right side in the y direction. Also, a first clamped portion 19a1 protruding leftward in the y direction is provided at the lower part of the first guide 19a on the left side in the y direction. The first clamped portion 19a1 is inserted into the first guide receiving portion 32b of the attachment portion 30. The first clamped portion 19a1 is used for the first guide 19a to hold the attachment portion 30 in a slidable state in the x direction.

[0024] (First engaging recess 19a2) A recess (first engaging recess 19a2) is formed in front of the first clamped portion 19a1 in the x direction. The first engaging recess 19a2 engages with the first engaging protrusion 32b1 of the first guide receiving portion 32b. By the engagement of the first engaging recess 19a2 and the first engaging protrusion 32b1, the movement of the attachment portion 30 backward in the x direction is completed.

[0025] (First temporary fixing claw 19b) Above the region protruding downward in the z - direction of the base 19, a first temporary fixing claw 19b is provided in the upward z - direction. Two first temporary fixing claws 19b are provided in the front x - direction and two in the rear x - direction respectively. The first temporary fixing claw 19b is used to latch the first flat surface portion 31a of the mounting portion 30 when the mounting portion 30 is lifted upward in the z - direction after the movement of the mounting portion 30 in the rear x - direction is completed.

[0026] Also, when the first electronic device 10 is attached to the vehicle roof 90, the first temporary fixing claw 19b is also latched to the vehicle attachment hole 91. By this latching, the first temporary fixing claw 19b sandwiches the vehicle roof 90 with the portion of the base 19 above the vehicle roof 90 in the z - direction, and the first electronic device 10 is temporarily fixed to the vehicle roof 90. However, the first temporary fixing claw 19b may be used only for latching to the vehicle attachment hole 91. In this case, the first temporary fixing claw 19b is not used as the first attachment structure. That is, the latching between the first temporary fixing claw 19b and the first flat surface portion 31a is not performed, and the fifth step described later is omitted.

[0027] (Contact convex portion 19c) In the region surrounded by the first guide 19a of the base 19, a contact convex portion 19c protruding downward in the z - direction is provided. The contact convex portion 19c is provided one each in the right y - direction and the lower y - direction. The protruding amount of the contact convex portion 19c downward in the z - direction is less than the protruding amount of the first guide 19a downward in the z - direction.

[0028] Also, in the region surrounded by the first guide 19a of the base 19, a hole through which the first connector 21 penetrates is provided behind the contact convex portion 19c in the x - direction.

[0029] Further, the base 19 is provided with a hole or a recess (base hole 19d) into which the first fastening portion 37 is screwed. The base hole 19d is provided between the contact convex portion 19c on the right side in the y direction and the contact convex portion 19c on the left side in the y direction. After the first electronic device 10 is temporarily fixed to the vehicle roof 90 and the attachment portion 30 is temporarily fixed to the first electronic device 10, the claw (first claw portion 32a1) of the contact portion 31 of the attachment portion 30 contacts the lower surface of the vehicle roof 90 by screwing the first fastening portion 37 and the base hole 19d. Thereby, electrical connection (grounding) between the first substrate 17 and the vehicle roof 90 is performed via the first substrate 17, the base 19, the contact portion 31, and the first fastening portion 37.

[0030] The base 19 may be made of a metal such as aluminum die-cast, or a part thereof may be made of metal and the other parts may be made of resin. The base 19 may be made of only resin.

[0031] (First connector 21) The first connector 21 is attached to the first substrate 17 and is used for electrical connection with the second substrate 53 of the second electronic device 50. The lower part of the first connector 21 protrudes downward in the z direction. The lower part of the first connector 21 passes through the hole of the base 19. The first connector 21 is fitted with a second connector 61 that passes through the third hole 51a2 of the housing 51 and the like.

[0032] When the first connector 21 and the second connector 61 are connected, power supply from the second electronic device 50 to the electronic components provided on the first substrate 17, signal transmission from the antenna element 15 to the second electronic device 50, and signal transmission from the second electronic device 50 to the antenna element 15 become possible. However, a cable (not shown) may be used for electrical connection with the first substrate 17 instead of the first connector 21.

[0033] (Configuration of attachment portion 30) Next, each part of the attachment portion 30 will be described. The attachment portion 30 is interposed between the first electronic device 10 and the second electronic device 50.

[0034] (Contact portion 31) As shown in FIGS. 7 and 8, the contact portion 31 has a first flat portion 31a, a claw portion (first claw portions 32a1 and 32a2, base portion 32a3), a first guide receiving portion 32b, and a second guide 32c. The contact portion 31 is provided at a position closer to the vehicle roof 90 than the main body portion 33.

[0035] The first flat portion 31a has a substantially rectangular shape and has a plane perpendicular to the z direction. A first hole 31a1 is provided in the first flat portion 31a. The length of the first hole 31a1 in the x direction is substantially the same as the length of the vehicle mounting hole 91 of the vehicle roof 90 in the x direction. A first guide 19a penetrates the first hole 31a1 from above in the z direction, and a second connector 61 penetrates from below in the z direction. The base portion 32a3 of the claw portion is attached to the region of the first flat portion 31a where the first hole 31a1 is located. A second flat portion 31a2 is formed in front of the first flat portion 31a in the x direction and at a position higher than the first flat portion 31a in the z direction. When the mounting portion 30 moves upward in the z direction with the first guide 19a reaching a first predetermined position, first temporary fixing claws 19b are hooked on the front and rear edges in the x direction of the peripheral edge of the first hole 31a1. Details of the first predetermined position will be described later.

[0036] (Claw portion of the contact portion 31) The claw portion of the contact portion 31 has first claw portions 32a1 and 32a2 and a base portion 32a3. In the present embodiment, the claw portion of the contact portion 31 is configured separately from other portions of the contact portion 31, but may be integrally configured. The first claw portions 32a1 are provided one each at both ends in the y direction of the base portion 32a3. One of the first claw portions 32a1 extends obliquely upward in the z direction from the right end in the y direction of the base portion 32a3 in a direction away from the base portion 32a3. The other of the first claw portions 32a1 extends obliquely upward in the z direction from the left end in the y direction of the base portion 32a3 in a direction away from the base portion 32a3. When the first electronic device 10 and the mounting portion 30 are connected in a positional relationship sandwiching the vehicle roof 90 and the first fastening portion 37 and the base hole 19d are screwed together, a part of the upper end portion of the first claw portion 32a1 bites into the lower surface of the vehicle roof 90, and the upper end portion comes into contact with the vehicle roof 90.

[0037] The second claw portions 32a2 are provided one by one at both ends of the first flat portion 31a in the x direction. The second claw portions 32a2 extend upward in the z direction from the end portions (front and rear ends) of the base portion 32a3 in the x direction. The second claw portions 32a2 have a plane perpendicular to the x direction.

[0038] The base portion 32a3 is substantially quadrilateral and has a plane perpendicular to the z direction. A hole through which the shaft portion of the first fastening portion 37 passes is provided in the base portion 32a3.

[0039] (The first guide receiving portion 32b) The first guide receiving portions 32b are provided at both ends of the first flat portion 31a in the y direction. One of the first guide receiving portions 32b protrudes upward in the z direction from the right end portion of the first flat portion 31a in the y direction and extends in the x direction. A groove is provided on the inner surface of one of the first guide receiving portions 32b, that is, on the surface where the other of the first guide receiving portions 32b is located. The other of the first guide receiving portions 32b protrudes upward in the z direction from the left end portion of the first flat portion 31a in the y direction and extends in the x direction. A groove is provided on the inner surface of the other of the first guide receiving portions 32b, that is, on the surface where the one of the first guide receiving portions 32b is located. The first guide 19a is fitted into the groove of the first guide receiving portion 32b.

[0040] Until the first guide 19a reaches the first predetermined position, the groove of the first guide receiving portion 32b is formed so as to restrict the upward movement of the mounting portion 30 in the z direction, and in a state where the first guide 19a reaches the first predetermined position, to release the restriction on the upward movement of the mounting portion 30 in the z direction. Therefore, the groove provided in the first guide receiving portion 32b has a narrow width in the z direction at least on the side where the insertion port is located. The width of the first guide receiving portion 32b in the z direction on the side where the insertion port is located is substantially equal to the width of the first clamped portion 19a1 in the z direction. The first predetermined position is a position where the first clamped portion 19a1 of the first guide 19a is inserted to the back of the first guide receiving portion 32b and approaches the second flat portion 31a2.

[0041] The first guide receiving portion 32b is provided with a first engaging convex portion 32b1. The first engaging convex portion 32b1 engages with the first engaging concave portion 19a2 when the first clamped portion 19a1 reaches the first predetermined position.

[0042] (The second guide 32c) A second guide 32c that protrudes downward in the z direction is formed in front of the second planar portion 31a2 in the x direction and behind the first planar portion 31a in the x direction. The second guide 32c is used for attaching the attachment portion 30 and the second electronic device 50. The second guide 32c is formed in a wall shape substantially perpendicular to the x direction. The second guide 32c is provided one each in the front and rear in the x direction.

[0043] (The second clamped portion 32c1) A second clamped portion 32c1 that protrudes in the x direction is provided at the lower portion of the second guide 32c. Specifically, a second clamped portion 32c1 that protrudes forward in the x direction is provided at the lower portion of the second guide 32c in the front in the x direction. Also, a second clamped portion 32c1 that protrudes rearward in the x direction is provided at the lower portion of the second guide 32c in the rear in the x direction. The second clamped portion 32c1 is inserted into the second guide receiving portion 52b of the second electronic device 50, and the second guide 32c is used to hold the second electronic device 50 in a slidable state in the y direction.

[0044] (The second engaging concave portion 32c2) A recess (the second engaging concave portion 32c2) is formed to the left in the y direction of the second clamped portion 32c1. The second engaging concave portion 32c2 engages with the second engaging convex portion 52b1 of the second guide receiving portion 52b (see FIG. 9). By the engagement of the second engaging concave portion 32c2 and the second engaging convex portion 52b1, the movement of the second electronic device 50 to the right in the y direction is completed.

[0045] (The main body portion 33) The main body portion 33 covers a part of the second electronic device 50 from above in the z direction. The main body portion 33 has an upper surface portion 33a, a first leg portion 33b, and a second leg portion 33c.

[0046] (The first region 331a, the second region 332a, the third region 333a) The upper surface portion 33a has a first region 331a, a second region 332a, and a third region 333a. The first region 331a has a substantially rectangular shape when viewed from the z direction. The second region 332a is provided to the right in the y direction of the first region 331a and has a substantially cross shape when viewed from the z direction. The third region 333a is provided to the left in the y direction of the first region 331a and has a substantially cross shape when viewed from the z direction. The first region 331a contacts the lower surface of the first flat surface portion 31a on the upper surface. A second hole 33a1 is provided in the first region 331a. The second hole 33a1 overlaps a part of the first hole 31a1 when viewed from the z direction. The first guide 19a penetrates the second hole 33a1 from above in the z direction, and the second connector 61 penetrates the second hole 33a1 from below in the z direction. A shaft hole 33a2 through which the shaft portion of the first fastening portion 37 penetrates is provided in the first region 331a.

[0047] (The first leg portion 33b) The first leg portions 33b are provided one by one at the right end in the y direction of the second region 332a of the upper surface portion 33a and the left end in the y direction of the third region 333a of the upper surface portion 33a. One of the first leg portions 33b extends obliquely downward in the z direction from the right end in the y direction of the second region 332a in a direction away from the first region 331a. The other of the first leg portions 33b extends obliquely downward in the z direction from the left end in the y direction of the third region 333a in a direction away from the first region 331a.

[0048] (The second leg portion 33c) The second leg portions 33c extend downward in the z direction from the x-direction ends of the second region 332a and the third region 333a of the upper surface portion 33a. The second leg portion 33c has a plane perpendicular to the x direction. At least two pairs of the second leg portions 33c are provided at both ends in the x direction of the second region 332a of the upper surface portion 33a and both ends in the x direction of the third region 333a of the upper surface portion 33a.

[0049] (The claw receiving portion 33c1) A hole (the claw receiving portion 33c1) is provided in the second leg portion 33c. When the second electronic device 50 moves upward in the z direction with the second guide 32c reaching the second predetermined position, the second temporary fixing claw 52c is hooked on the claw receiving portion 33c1. Details of the second predetermined position will be described later.

[0050] (First wrist part 35) The first wrist part 35 has a plane perpendicular to the z direction. One side of the first wrist part 35 extends so as to protrude rightward in the y direction from the lower end of the first leg part 33b. The other side of the first wrist part 35 extends so as to protrude leftward in the y direction from the lower end of the first leg part 33b. The first wrist part 35 is provided below the upper surface part 33a in the z direction. That is, the first wrist part 35 is provided at a position farther from the vehicle roof 90 than the upper surface part 33a. A first wrist part hole 35a is provided in the first wrist part 35. The second fastening part 57 penetrates the first wrist part hole 35a.

[0051] (Configuration of the main body part 33 and the first wrist part 35) The main body part 33 and the first wrist part 35 are integrally formed of metal. For example, the main body part 33 and the first wrist part 35 are formed by bending a metal plate-like member or the like. However, the part in contact with the contact part 31 of the upper surface part 33a of the main body part 33 may be formed of metal, and other parts may be formed of a non-metal such as resin.

[0052] (Configuration of the contact part 31 and the main body part 33) The contact part 31 and the main body part 33 are formed separately and are connected by adhesion, welding or the like. However, the contact part 31 and the main body part 33 may be integrally formed of metal.

[0053] (Non-contact of the main body part 33) When the mounting part 30 is attached to the first electronic device 10, it is desirable that the dimensions of the contact part 31 and the main body part 33 be determined so that the main body part 33 is in a positional relationship where it does not contact the vehicle roof 90. In this case, the main body part 33 covers a part of the second electronic device 50 from above in the z direction in a positional relationship where it does not contact the vehicle roof 90. Thereby, an electrical connection between the mounting part 30 and the vehicle roof 90 can be made non-existent at locations other than the contact part 31. Also, for the purpose of preventing the main body part 33 from temporarily contacting the vehicle roof 90 due to vibrations of the vehicle or the like, a cushioning material (not shown) made of an insulating member may be provided between the main body part 33 and the vehicle roof 90.

[0054] (First fastening part 37) The first fastening part 37 is composed of a bolt or the like and is used for screwing with the base hole 19d of the base 19. In this embodiment, an example where the first fastening part 37 is a bolt is shown. By screwing the base 19 and the first fastening part 37, the first electronic device 10 and the mounting part 30 are connected in a positional relationship that sandwiches the vehicle roof 90.

[0055] (Configuration of the second electronic device 50) Next, each part of the second electronic device 50 will be described with reference to FIGS. 2, 9, 10, etc.

[0056] (Housing 51) The housing 51 has a substantially rectangular parallelepiped shape and houses the second substrate 53. The central part of the upper surface of the housing 51 has an upper surface recess 51a that is recessed downward in the z direction from the peripheral part of the upper surface.

[0057] A fastening part storage part 51a1 is provided in the upper surface recess 51a. The fastening part storage part 51a1 is a recess provided in the upper surface recess 51a. The fastening part storage part 51a1 is provided at a position that faces the second hole 33a1 in the z direction when the second electronic device 50 is attached to the mounting part 30, specifically, when the second guide 32c reaches the second predetermined position. The fastening part storage part 51a1 houses the head of the bolt that constitutes the first fastening part 37. Details of the second predetermined position will be described later.

[0058] Also, a third hole 51a2 through which the first guide 19a and the second connector 61 penetrate is provided in the upper surface recess 51a. The third hole 51a2 is provided at a position that faces the first hole 31a1 and the second hole 33a1 in the z direction when the second electronic device 50 is attached to the mounting part 30, specifically, when the second guide 32c reaches the second predetermined position.

[0059] Also, a fourth hole 51a3 through which the second guide 32c penetrates is provided in the connection region of the upper surface recess 51a with the second guide receiving part 52b. The fourth hole 51a3 is provided at a position that faces the lower end of the second guide 32c when the second electronic device 50 is attached to the mounting part 30, specifically, when the second guide 32c reaches the second predetermined position.

[0060] (Guide receiving convex portion 51b, guide receiving surface 51c) On the upper surface of the housing 51, on the right side in the y direction, a guide receiving convex portion 51b protruding in the z direction is provided. The width of the guide receiving convex portion 51b in the x direction is shorter than the distance in the x direction between one side and the other side of the second guide 32c. Between the region where the guide receiving convex portion 51b is provided on the upper surface of the housing 51 and the front end in the x direction, and between the region where the guide receiving convex portion 51b is provided on the upper surface of the housing 51 and the rear end in the x direction, a surface perpendicular to the z direction (guide receiving surface 51c) is provided. The guide receiving convex portion 51b and the guide receiving surface 51c are used for positioning the second guide 32c when attaching the attachment portion 30 and the second electronic device 50. Specifically, the second guide 32c is disposed on the guide receiving surface 51c in a positional relationship that sandwiches the guide receiving convex portion 51b in the x direction, and then is inserted into the second guide receiving portion 52b.

[0061] (Housing convex portion 51d) On the upper surface of the housing 51, on the left side in the y direction, a housing convex portion 51d protruding in the z direction is provided. The width of the housing convex portion 51d in the x direction is longer than the distance in the x direction between one side and the other side of the second guide 32c. Therefore, the second guide 32c cannot sandwich the housing convex portion 51d in the x direction. As a result, it is possible to make it difficult to misalign the positional relationship when attaching the second electronic device 50 to the attachment portion 30.

[0062] (Second guide receiving portion 52b) On the upper surface of the housing 51, at the center in the y direction and at both ends in the x direction, second guide receiving portions 52b are provided. One of the second guide receiving portions 52b protrudes upward in the z direction from the front end in the x direction at the center in the y direction on the upper surface of the housing 51 and extends in the y direction. A groove is provided on the inner surface of one of the second guide receiving portions 52b, that is, the surface on the side where the other of the second guide receiving portions 52b is located. The other of the second guide receiving portions 52b protrudes upward in the z direction from the rear end in the x direction at the center in the y direction on the upper surface of the housing 51 and extends in the y direction. A groove is provided on the inner surface of the other of the second guide receiving portions 52b, that is, the surface on the side where one of the second guide receiving portions 52b is located. The second guide 32c is fitted into the groove of the second guide receiving portion 52b.

[0063] Until the second guide 32c reaches the second predetermined position, the groove of the second guide receiving portion 52b is formed so as to restrict the upward movement of the second electronic device 50 in the z direction, and in a state where the second guide 32c has reached the second predetermined position, the upward movement of the second electronic device 50 in the z direction is released. Therefore, the second guide receiving portion 52b is provided with a groove having a narrow width in the z direction on at least the side where the insertion port is located. The width of the second guide receiving portion 52b in the z direction on the side where the insertion port is located is substantially equal to the width of the second sandwiched portion 32c1 in the z direction. The second predetermined position is a position where the second sandwiched portion 32c1 of the second guide 32c is inserted to the depth of the second guide receiving portion 52b and approaches the housing convex portion 31d.

[0064] The second guide receiving portion 52b is provided with a second engaging convex portion 52b1. The second engaging convex portion 52b1 engages with the second engaging concave portion 32c2 when the second sandwiched portion 32c1 reaches the second predetermined position.

[0065] (Second temporary fixing claw 52c) Second temporary fixing claws 52c are provided on the right side and the left side in the y direction on the front surface of the housing 51. Similarly, second temporary fixing claws 52c are provided on the right side and the left side in the y direction on the rear surface of the housing 51. The second temporary fixing claw 52c is used to hook the claw receiving portion 33c1 of the mounting portion 30 when the second electronic device 50 is lifted upward in the z direction after the movement of the second electronic device 50 to the right in the y direction is completed.

[0066] (Second substrate 53) The second substrate 53 is connected to the gateway ECU of the vehicle via a cable (not shown) of in-vehicle LAN. The second substrate 53 mutually converts digital signals and analog signals. Specifically, the second substrate 53 transmits and receives signals received by the antenna element 15 and signals transmitted by the antenna element 15 to and from the gateway ECU in digital signals.

[0067] The gateway ECU transmits and receives signals to and from in-vehicle electronic devices such as information processing devices via the in-vehicle LAN. The information processing device is a device that outputs information such as voice and video, such as a car navigation system and audio equipment.

[0068] The second substrate has, for example, an FM / AM tuner, a communication module, a position calculation module, a V2X module, an SXM·DAB module, etc.

[0069] (Second arm portion 55) The second arm portion 55 has a plane perpendicular to the z direction. One side of the second arm portion 55 extends so as to protrude rightward in the y direction from the right side surface of the housing 51 in the y direction. The other side of the second arm portion 55 extends so as to protrude leftward in the y direction from the left side surface of the housing 51 in the y direction.

[0070] The second arm portion 55 is provided below the upper surface of the housing 51 in the z direction. That is, the second arm portion 55 is provided at a position farther from the vehicle roof 90 than the upper surface of the housing 51. The second arm portion 55 is provided with a second arm hole 55a through which the second fastening portion 57 passes. The second arm hole 55a is provided at a position facing the first arm hole 35a in the z direction when the second electronic device 50 is attached to the attachment portion 30, specifically, when the second guide 32c reaches the second predetermined position. Before the in-vehicle device 1 is attached to the vehicle roof 90, the second fastening portion 57 is attached to the second arm portion 55.

[0071] (Second fastening portion 57) The second fastening portion 57 is composed of a clip or the like and penetrates the second arm hole 55a and the first arm hole 35a from below in the z direction. By the second fastening portion 57 penetrating the second arm hole 55a and the first arm hole 35a, the second electronic device 50 is fixed to the attachment portion 30 (see FIG. 10).

[0072] (Attachment procedure) Next, the procedure for an operator of vehicle assembly or the like to attach the in-vehicle device 1 to the vehicle roof 90 will be described. In advance, the first electronic device 10 is assembled (see FIG. 3). Also, the attachment portion 30 is assembled (see FIG. 7). The first fastening portion 37 is inserted from below in the z direction in a state where the shaft portion of the first fastening portion 37 in the shaft hole 33a2 and the base portion 32a3 passes through the hole. Further, the second electronic device 50 is assembled. The second fastening portion 57 is inserted from below in the z direction in a state where it is inserted into the second arm portion hole 55a.

[0073] First, the operator inserts the first connector 21 of the first electronic device 10 and the first guide 19a of the base 19 into the vehicle attachment hole 91 of the vehicle roof 90 from above in the z direction. The first temporary fixing claw 19b is hooked on the peripheral portion of the vehicle attachment hole 91, and the first electronic device 10 is temporarily fixed to the vehicle roof 90 (first step, see FIG. 2).

[0074] Next, the operator brings the attachment portion 30 closer to the first guide 19a from the front in the x direction (second step, see FIGS. 11 and 12). Specifically, from the front in the x direction, the insertion port of the first guide receiving portion 32b of the attachment portion 30 is brought closer to the first sandwiched portion 19a1 of the first guide 19a.

[0075] Next, the operator moves the attachment portion 30 backward in the x direction (third step, see FIGS. 13 and 14). Specifically, the first sandwiched portion 19a1 of the first guide 19a is fitted into the groove of the first guide receiving portion 32b. The width in the z direction of the groove on the insertion port side of the first guide receiving portion 32b is narrow. For this reason, the movement of the first sandwiched portion 19a1 in the z direction is restricted.

[0076] Next, the operator further moves the mounting portion 30 rearward in the x direction (refer to the fourth step, FIGS. 15 and 16). When the first clamped portion 19a1 reaches the first predetermined position and the first engaging concave portion 19a2 of the first guide 19a engages with the first engaging convex portion 32b1 of the first guide receiving portion 32b, the movement of the mounting portion 30 rearward in the x direction is completed. At this time, the first guide 19a and the first connector 21 are in a state where the first hole 31a1 and the second hole 33a1 face each other in the z direction. Also, the base hole 19d of the base 19 and the first fastening portion 37 are in a state where they face each other in the z direction. The back side (the side closer to the second flat portion 31a2) of the first guide receiving portion 32b has the groove omitted or the z-direction width of the back side groove is wide. For this reason, the first clamped portion 19a1 can move upward in the z direction.

[0077] Next, the operator moves the mounting portion 30 upward in the z direction. The first temporary fixing claw 19b is hooked on the peripheral edge of the first hole 31a1, and the mounting portion 30 is temporarily fixed to the first electronic device 10 (refer to the fifth step, FIGS. 17 and 18). At this time, the first guide 19a and the first connector 21 are in a state of passing through the first hole 31a1 and the second hole 33a1. Note that if the first temporary fixing claw 19b is not hooked on the peripheral edge of the first hole 31a1, the fifth step is omitted.

[0078] Next, the operator screws the first fastening portion 37 (refer to FIG. 15) into the base hole 19d (refer to FIG. 15). As a result, the mounting portion 30 moves upward in the z direction, and the first electronic device 10 and the mounting portion 30 are fixed to the vehicle roof 90 in a positional relationship where at least a part of the vehicle roof 90 is sandwiched between them in the z direction. Also, by tightening the first fastening portion 37, the first claw portion 32a1 of the contact portion 31 is connected to the vehicle roof 90 (refer to the sixth step, FIG. 19).

[0079] Next, the operator moves the second electronic device 50 closer to the second guide 32c from the left in the y direction (refer to the seventh step, FIGS. 20 and 21). Specifically, the second guide 32c is disposed on the guide receiving surface 51c in a positional relationship that sandwiches the guide receiving convex portion 51b in the x direction. As a result, the insertion port of the second guide receiving portion 52b of the second electronic device 50 approaches the second sandwiched portion 32c1 of the second guide 32c.

[0080] Next, the operator moves the second electronic device 50 to the right in the y direction (refer to the eighth step, FIGS. 22 and 23). Specifically, the second sandwiched portion 32c1 of the second guide 32c is fitted into the groove of the second guide receiving portion 52b. The width in the z direction of the groove on the insertion port side of the second guide receiving portion 52b is narrow. Therefore, the movement of the second sandwiched portion 32c1 in the z direction is restricted.

[0081] Next, the operator further moves the second electronic device 50 to the right in the y direction (refer to the ninth step, FIGS. 24 and 25). When the second sandwiched portion 32c1 reaches the second predetermined position and the second engaging concave portion 32c2 of the second guide 32c engages with the second engaging convex portion 52b1 of the second guide receiving portion 52b, the movement of the second electronic device 50 to the right in the y direction is completed.

[0082] At this time, the first guide 19a and the third hole 51a2 face each other in the z direction. Also, the first connector 21 and the second connector 61 face each other in the z direction. Also, the second guide 32c and the fourth hole 51a3 face each other in the z direction. Also, the first arm hole 35a and the second arm hole 55a face each other in the z direction. Also, the first fastening portion 37 and the fastening portion storage portion 51a1 face each other in the z direction. On the inner side (the side closer to the housing convex portion 31d) of the second guide receiving portion 52b, the groove is omitted or the width in the z direction of the inner groove is wide. Therefore, the second sandwiched portion 32c1 can move upward in the z direction.

[0083] Next, the operator moves the second electronic device 50 upward in the z direction. The second temporary fixing claw 52c is hooked on the claw receiving portion 33c1, and the second electronic device 50 is temporarily fixed to the mounting portion 30 (refer to the tenth step, FIGS. 26 and 27).

[0084] At this time, the first guide 19a penetrates through the third hole 51a2. Also, the second guide 32c penetrates through the fourth hole 51a3. Further, the head of the first fastening part 37 is in a state of being housed in the fastening part housing part 51a1.

[0085] Next, the operator inserts the second fastening part 57 into the first arm part hole 35a of the first arm part 35 and latches it. At this time, the first connector 21 and the second connector 61 are in a state of being fitted and electrically connected. Thereby, the second electronic device 50 is fixed to the mounting part 30 in a positional relationship where the second electronic device 50 and the vehicle roof 90 sandwich at least a part of the mounting part 30 in the z direction (see the 11th step, FIGS. 28 and 29). The attachment of the in-vehicle device 1 to the vehicle roof 90 is completed.

[0086] (Effect of providing a mounting structure by sliding movement in the x direction or y direction and movement in the z direction) Using the mounting part 30 provided between the second electronic device 50 and the wall-like member of the vehicle (vehicle roof 90), the first electronic device 10 is fixed to the wall-like member of the vehicle (vehicle roof 90) in the previous stage (the first step to the sixth step), and in the latter stage (the seventh step to the 11th step), the second electronic device 50 is fixed to the mounting part 30. After moving at least one of the first electronic device 10 and the mounting part 30 by sliding (sliding movement in the x direction), the movement in the first direction (z direction) is performed to attach the first electronic device 10 and the mounting part 30, and / or after moving at least one of the mounting part 30 and the second electronic device 50 by sliding (sliding movement in the y direction), the movement in the first direction (z direction) is performed to attach the mounting part 30 and the second electronic device 50. Thereby, even in a state where the connection part is difficult to see from below or the like, the attachment of the first electronic device 10 and the mounting part 30 and / or the attachment of the mounting part 30 and the second electronic device 50 can be performed. That is, the attachment of the in-vehicle device 1 including the first electronic device 10 and the second electronic device 50 to the vehicle can be easily performed.

[0087] (Effect of providing a guide and a guide receiving part) By holding the first guide receiving portion 32b by the first guide 19a in a slidable state (capable of sliding movement in the x direction) and movable in the first direction (z direction), at least one of the first electronic device 10 and the mounting portion 30 can be easily slid (slid movement in the x direction) and moved in the first direction (z direction). By holding the second guide receiving portion 52b by the second guide 32c in a slidable state (capable of sliding movement in the y direction) and movable in the first direction (z direction), at least one of the mounting portion 30 and the second electronic device 50 can be easily slid (slid movement in the y direction) and moved in the first direction (z direction).

[0088] (Effect of providing engaging convex portion and engaging concave portion) Before and after engagement, the feel of the operation changes. Therefore, even in a state where it is difficult to see whether the first guide 19a has reached the first predetermined position, the operator can know the arrival of the first guide 19a at the first predetermined position by the feel of the operation. Similarly, even in a state where it is difficult to see whether the second guide 32c has reached the second predetermined position, the operator can know the arrival of the second guide 32c at the second predetermined position by the feel of the operation.

[0089] (Effect of providing the first temporary fixing claw 19b on the first electronic device 10) The first temporary fixing claw 19b can be utilized to temporarily fix the first electronic device 10 to the wall-like member (vehicle roof 90) of the vehicle.

[0090] (Effect of providing the first temporary fixing claw 19b and the second temporary fixing claw 52c) When the first temporary fixing claw 19b is latched with the first flat portion 31a, the temporary fixing by the first temporary fixing claw 19b maintains the mounting portion 30 in a state of being moved in the first direction (z direction), and subsequent fixing (fastening) can be easily performed. The temporary fixing by the second temporary fixing claw 52c maintains at least one of the mounting portion 30 and the second electronic device 50 in a state of being moved in the first direction (z direction), and subsequent fixing (latching) can be easily performed.

[0091] (Effect of applying the in-vehicle device 1 to the antenna device) When attaching the first electronic device 10 and the second electronic device 50 via the attachment part 30, it is possible to establish an electrical connection (grounding) between the first electronic device 10 and the wall-like member of the vehicle (vehicle roof 90), and also an electrical connection between the first electronic device 10 and the second electronic device 50.

[0092] (Effect of the contact part 31 of the attachment part 30 functioning as a claw washer) When using the first electronic device 10 as an antenna part, it is possible to use, as the first electronic device 10, a device having substantially the same configuration as a normal antenna device without using the second electronic device (signal processing part) 50.

[0093] (Effect of housing the head of the first fastening part 37) The head of the first fastening part 37 is housed in the fastening part housing part 51a1 of the housing 51. Therefore, after the attachment is completed, the head of the first fastening part 37 is in a state where it is difficult to touch the outside, and it is possible to prevent the tightening of the first fastening part 37 from becoming loose.

[0094] (Effect of providing the arm part) The first arm part 35 provided on the first leg part 33b is in a state where the tip of the first arm part 35 is movable (flapping state) around the connection part between the first arm part 35 and the first leg part 33b due to elastic deformation. Therefore, when the second electronic device 50 moves due to vibrations of the vehicle or the like, it is possible to reduce the force applied to the first connector 21.

[0095] (Effect of providing the arm part at a low position) The first arm part 35 is provided below the upper surface part 33a in the z direction. Therefore, it is possible to provide a space for the tip of the second fastening part 57 such as a clip to protrude between the first arm part 35 and the vehicle roof 90.

[0096] (Application example of the arrangement of the guide and the guide receiving part) In this embodiment, as the first mounting structure, an example in which the first guide 19a is provided on the first electronic device 10 and the first guide receiving portion 32b is provided on the mounting portion 30 has been described. Further, as the second mounting structure, an example in which the second guide 32c is provided on the mounting portion 30 and the second guide receiving portion 52b is provided on the second electronic device 20 has been described.

[0097] However, the first mounting structure and the second mounting structure are not limited to these configurations. For example, as the first mounting structure, a member corresponding to the first guide 19a may be provided on the mounting portion 30, and a member corresponding to the first guide receiving portion 32b may be provided on the first electronic device 10. Further, as the second mounting structure, a member corresponding to the second guide 32c may be provided on the second electronic device 20, and a member corresponding to the second guide receiving portion 52b may be provided on the mounting portion 30.

[0098] (Example of application of the temporary fixing claw) Also, in this embodiment, as the first mounting structure, an example in which the first temporary fixing claw 19b is provided on the first electronic device 10 and the receiving portion of the first temporary fixing claw 19b (the first hole 31a1) is provided on the mounting portion 30 has been described. Further, as the second mounting structure, an example in which the receiving portion of the second temporary fixing claw 52c (the claw receiving portion 33c1) is provided on the mounting portion 30 and the second temporary fixing claw 52c is provided on the second electronic device 50 has been described.

[0099] However, the first mounting structure and the second mounting structure are not limited to these configurations. For example, as the first mounting structure, a member corresponding to the receiving portion of the first temporary fixing claw 19b (the first hole 31a1) may be provided on the first electronic device 10, and a member corresponding to the first temporary fixing claw 19b may be provided on the mounting portion 30. Further, as the second mounting structure, a member corresponding to the second temporary fixing claw 52c may be provided on the mounting portion 30, and a member corresponding to the receiving portion of the second temporary fixing claw 52c (the claw receiving portion 33c1) may be provided on the second electronic device 50.

[0100] (Example of application of the sliding body) In addition, in this embodiment, an example in which the mounting portion 30 slides rearward in the x direction and the second to fourth steps are executed has been described. Also, an example in which the second electronic device 50 slides rightward in the y direction and the seventh to ninth steps are executed has been described.

[0101] However, the sliding forms in the direction perpendicular to the z direction of the first mounting structure and the second mounting structure are not limited to these configurations. For example, the first electronic device 10 may slide forward in the x direction and the second to fourth steps may be executed, or the first electronic device 10 and the mounting portion 30 may slide so as to approach each other and the second to fourth steps may be executed. Also, the mounting portion 30 may slide leftward in the y direction and the seventh to ninth steps may be executed, or the mounting portion 30 and the second electronic device 50 may slide so as to approach each other and the seventh to ninth steps may be executed.

[0102] (Application examples of the sliding body) In addition, in this embodiment, an example in which the sliding direction of the first mounting structure and the sliding direction of the second mounting structure are orthogonal to each other has been described. In this case, it is possible to make it difficult to mistake the procedures of the movement in the x direction in the second to fourth steps and the movement in the y direction in the seventh to ninth steps.

[0103] However, the sliding direction of the first mounting structure and the sliding direction of the second mounting structure are not limited to being orthogonal. For example, the sliding direction of the first mounting structure and the sliding direction of the second mounting structure may be different non-orthogonal directions, or may both be in the x direction (or y direction).

[0104] (Application examples of the z-direction movement) In addition, in this embodiment, an example in which the mounting portion 30 moves upward in the z direction and the fifth to sixth steps are executed has been described. Also, an example in which the second electronic device 50 moves upward in the z direction and the tenth to eleventh steps are executed has been described.

[0105] However, the forms of movement in the z - direction of the first mounting structure and the second mounting structure are not limited to these configurations. For example, the first electronic device 10 may move downward in the z - direction and the fifth to sixth steps may be executed, or the mounting portion 30 may move downward in the z - direction and the tenth to eleventh steps may be executed.

[0106] (Application examples of the engaging convex portion and the engaging concave portion) Also, in this embodiment, an example in which the first engaging concave portion 19a2 is provided on the first guide 19a and the first engaging convex portion 32b1 is provided on the first guide receiving portion 32b has been described. However, a convex portion corresponding to the first engaging convex portion 32b1 may be provided on the first guide 19a, and a concave portion corresponding to the first engaging concave portion 19a2 may be provided on the first guide receiving portion 32b.

[0107] (Application examples of the first mounting structure and the second mounting structure) Also, in this embodiment, an example in which the first electronic device 10 and the mounting portion 30 are attached via the first mounting structure, and the mounting portion 30 and the second electronic device 50 are attached via the second mounting structure has been described. However, the first electronic device 10 and the mounting portion 30 may be attached via the first mounting structure, and the mounting portion 30 and the second electronic device 50 may be attached via a structure different from the second mounting structure. Also, the first electronic device 10 and the mounting portion 30 may be attached via a structure different from the first mounting structure, and the mounting portion 30 and the second electronic device 50 may be attached via the second mounting structure.

[0108] (Application examples to devices other than the antenna device) Also, in this embodiment, the vehicle - mounted device 1 has been described as a vehicle - mounted antenna device, and an example in which the first electronic device 10 is an antenna portion and the second electronic device 50 is a signal processing portion has been described.

[0109] However, the in-vehicle device 1 is not limited to these configurations. For example, a configuration where the first electronic device 10 is an imaging device such as a rear view camera, and the second electronic device 50 is a signal processing unit that performs image processing on the data obtained by the imaging device is conceivable. Additionally, a configuration where the first electronic device 10 is a signal processing unit and the second electronic device 50 is an antenna unit is also conceivable.

[0110] (Application Example of the Arrangement of the First Electronic Device 10) Also, in this embodiment, an example has been described where the first electronic device 10 is arranged outside the vehicle, the second electronic device 50 is arranged inside the vehicle, the first electronic device 10 and the mounting portion 30 are attached in a positional relationship sandwiching the vehicle roof 90, and then the second electronic device 50 is attached to the mounting portion 30.

[0111] However, the in-vehicle device 1 is not limited to these configurations. For example, a configuration where the first electronic device 10 and the second electronic device 50 are arranged inside the vehicle, the first electronic device 10 and the mounting portion 30 are attached in a positional relationship sandwiching a wall-like member (attachment object) of the vehicle, and then the second electronic device 50 is attached to the mounting portion 30 is conceivable.

[0112] (Application Example of the Arrangement of the Second Electronic Device 50) Also, in this embodiment, an example has been described where the first electronic device 10, the mounting portion 30, and the second electronic device 50 are arranged in a straight line in the z direction or the like, that is, the second electronic device 50 is arranged below the first electronic device 10 in the z direction.

[0113] However, the arrangement of the first electronic device 10, the mounting portion 30, and the second electronic device 50 is not limited to this. For example, a configuration where the second electronic device 50 is arranged at a position shifted downward in the z direction from the first electronic device 10 and forward in the x direction or rightward in the y direction, and such a second electronic device 50 is attached to the mounting portion 30 is conceivable.

[0114] Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, as well as in the invention described in the claims and the equivalent scope thereof.

[0115] According to this specification, the following aspects are provided. (Aspect 1) The in-vehicle device includes a first electronic device, a mounting portion, and a second electronic device electrically connected to the first electronic device.
