Description

This case concerns a mounting structure for mounting on-board equipment to a vehicle.

Various mounting structures for mounting on-board equipment to a vehicle have been proposed in the past. For example, Patent Document 1 discloses a structure for fixing on-board equipment to a vehicle via a vehicle body side bracket fixed to the vehicle body and a main body side bracket fixed to the on-board equipment main body.

JP 2022-15724 A

However, when an in-vehicle device is fixed (attached) to a bracket fixed to the vehicle body at a position offset from the center of gravity of the in-vehicle device, it is prone to vibrating or swaying due to the influence of vehicle vibrations, a phenomenon known as fluttering. Such fluttering is particularly likely to occur when the in-vehicle device is fixed to the bracket at only one point. Furthermore, in this case, the fixing strength of the in-vehicle device to the bracket may also be reduced.

This invention was conceived in consideration of the above problems, and one of its objectives is to both improve the fixing strength of the in-vehicle equipment and suppress flapping. However, this objective is not the only objective, and another objective of this invention is to achieve effects that cannot be obtained by conventional technology, which are derived from the configurations shown in the description of the embodiment of the invention described below.

The disclosed mounting structure can be realized as the aspects or application examples disclosed below, and solves at least some of the above problems.
The mounting structure disclosed herein is a mounting structure for mounting an in-vehicle device to a vehicle, and includes a bracket provided separately from the in-vehicle device and to which the in-vehicle device is attached. The bracket has a base fixed to the vehicle, and at least three insertion pieces extending upward from the base and spaced apart from each other and arranged in parallel in one direction. The in-vehicle device has three fitting portions that open downward at an upper portion thereof and are spaced apart from each other and arranged in parallel in the one direction, and is fixed to the bracket by fitting one of the insertion pieces into each of the fitting portions.

The disclosed mounting structure allows for three-point fixation by fitting one insertion piece into each of the three fitting portions, thereby improving the fixing strength of the vehicle-mounted device and suppressing flapping.

FIG. 11 is a plan view showing the mounting structure according to the embodiment, as viewed from the other side of the second direction. 11 is a plan view of the vehicle-mounted device provided in the mounting structure according to the embodiment, viewed from the other side of the second direction. FIG. FIG. 4 is a plan view of the in-vehicle device of FIG. 3 as viewed from below. 2 is a partial cross-sectional view of an in-vehicle device provided in the mounting structure of FIG. 1, taken along the line XX of FIG.

The mounting structure as an embodiment will be described with reference to the drawings. The embodiments shown below are merely examples, and are not intended to exclude the application of various modifications or techniques not explicitly stated in the following embodiments. Each configuration of this embodiment can be modified in various ways without departing from the spirit of the embodiment. In addition, they can be selected or combined as necessary.

The mounting structure of the embodiment is a mounting structure for mounting an on-vehicle device to a vehicle. The mounting structure has a bracket that is provided separately from the on-vehicle device and is fixed to the vehicle. The bracket has at least three insert pieces, and the on-vehicle device has three fitting parts that open downward at the upper part. The mounting structure of the embodiment is characterized in that the on-vehicle device is fixed to the bracket by fitting at least three insert pieces one by one from below into each of the three fitting parts. The term "one by one" here means that "one insert piece fits into one fitting part" and has no time meaning. For example, each insert piece may be fitted into each fitting part at the same time, or may be fitted in order. Note that "upper" and "lower" in the claims refer to one side (upper) and the other side (lower) of the "vertical direction" defined based on the state in which the vehicle is stopped on a flat road surface, and include not only directions that correspond to "vertical upper" and "vertical lower", but also inclined directions.

[1. Configuration]
1 is a perspective view showing a state in which an in-vehicle device 1 is attached to a bracket 2 by the mounting structure of this embodiment. The in-vehicle device 1 is, for example, an electronic device mounted on a vehicle (not shown). The in-vehicle device 1 of this embodiment is a signal conversion device that converts an input video signal and sends the converted signal to an in-vehicle navigation device (not shown). The in-vehicle device 1 is disposed, for example, on the back side of an instrument panel (not shown).

The bracket 2 is a sheet metal member that is fixed to the vehicle, and as described above, is provided separately from the in-vehicle device 1. The bracket 2 is fixed, for example, to a member that constitutes the body of the vehicle, or to a bracket fixed to this member. In this embodiment, the bracket 2 is illustrated as being mounted on a pair of gatepost brackets (not shown) that are suspended from a deck cross member (not shown).

The bracket 2 has a base 21 that is fixed to the vehicle, and at least three insertion pieces 22 that extend upward from the base 21. Here, a bracket 2 having five insertion pieces 22 is illustrated. As shown in FIG. 2, the five insertion pieces 22 are arranged side by side at a distance from each other in a direction different from the vertical direction. In this embodiment, the five insertion pieces 22 are arranged side by side in a direction perpendicular to the vertical direction (e.g., the vehicle width direction). Hereinafter, the direction in which the insertion pieces 22 are arranged side by side (parallel direction) is referred to as the first direction. Also, the direction perpendicular to both the vertical direction and the first direction (e.g., the front-rear direction) is referred to as the second direction. Note that in FIG. 2, only the hidden lines of the bracket 2 are shown by dashed lines.

Each insertion piece 22 has a substantially identical shape and is flat with a surface facing the second direction (plate thickness direction). The shape of each insertion piece 22 is, for example, substantially rectangular when viewed from the second direction. Each insertion piece 22 is provided with an engagement hole 22h that penetrates in the second direction.

Three of the five insertion pieces 22 are configured to be inserted from below into each of the three fitting portions 32 of the vehicle-mounted device 1, which will be described later. This fixes the vehicle-mounted device 1 to the bracket 2. Hereinafter, the three insertion pieces 22 that fit into the fitting portions 32 are also referred to as "regular insertion pieces 22R". In addition, the state in which each of the regular insertion pieces 22R fits into each of the three fitting portions 32 (i.e., the state in which the vehicle-mounted device 1 is fixed to the bracket 2) is referred to as the "mounted state". In this embodiment, the portion of the vehicle-mounted device 1 other than the three fitting portions 32 is disposed on one side of the bracket 2 in the second direction in the mounted state, as shown in FIG. 1. The remaining insertion pieces 22 that are not regular insertion pieces 22R can be used for other purposes (for example, to attach another member or to support another cable as will be described later).

As shown in FIG. 2, the base 21 has one connecting portion 21a and two legs 21b. The connecting portion 21a is a portion that connects the lower ends of the respective insertion pieces 22, and is flat with a surface facing the second direction like the insertion pieces 22, and extends in the first direction. Note that, as shown in FIG. 1, the bracket 2 of this embodiment has an L-shaped piece that extends from the upper edge of the connecting portion 21a to the other side of the second direction and then bends upward between adjacent insertion pieces 22, but since this L-shaped piece does not have a function in this mounting structure, it may be omitted.

The two legs 21b are portions that extend downward from the connecting portion 21a. As shown in FIG. 2, the two legs 21b are spaced apart from each other in the first direction. The two legs 21b, together with a protrusion 33 (described later) of the on-vehicle component 1, function to easily check whether the on-vehicle component 1 is properly attached. In this embodiment, the legs 21b extend downward from positions that avoid both ends of the connecting portion 21a.

The base 21 of this embodiment further has two fixing parts 21c that are fixed to a vehicle. In this embodiment, each fixing part 21c extends from the lower part of each leg part 21b in the opposite direction to the first direction. For example, a fastening hole penetrating in the second direction is provided in the fixing part 21c. The bracket 2 is fixed to the gatepost bracket by a fastening part (for example, a bolt and a nut or a clip) that is inserted into the fastening hole. Note that the fixing part 21c may be provided at a position offset in the second direction with respect to each leg part 21b as shown in FIG. 1. Alternatively, the fixing part 21c may be omitted, and the first direction dimension of each leg part 21b may be enlarged and a fastening hole may be provided in its lower part, so that the leg part 21b functions as the fixing part 21c.

As described above, the vehicle-mounted device 1 of this embodiment is a signal conversion device that converts an input video signal. In this embodiment, the vehicle-mounted device 1 includes a main body component 3 (main body portion) that incorporates electronic components (not shown) that function as a signal conversion device, a connector 4 that is connected to the main body component 3, and a connector cover 5 that covers the connector 4. The vehicle-mounted device 1 is configured by assembling these components 3 to 5 into a single assembly component.

As shown in Figs. 1 to 3, the main body component 3 has a housing portion 31 and three fitting portions 32. In this embodiment, the main body component 3 further has a protrusion portion 33 and a connection portion 34. The housing portion 31 is a portion that houses the electronic components described above, and as shown in Fig. 1, has a substantially rectangular parallelepiped shape with faces facing the up and down directions, the first direction, and the second direction.

Among the surfaces of the housing 31, the first side surface 31a (flat surface, see FIG. 2) that forms the surface facing the other side of the second direction is disposed opposite the base 21 of the bracket 2 in the mounted state. A protrusion 33 that protrudes from the first side surface 31a in the other side of the second direction is provided at the lower part of the first side surface 31a, as shown in FIGS. 2 and 3. This protrusion 33 is located between the two legs 21b in the mounted state, and is provided at a position where it interferes with either of the two legs 21b when an insertion piece 22 other than the regular insertion piece 22R is fitted into the fitting portion 32, i.e., in a state other than the mounted state. The protrusion length of the protrusion 33 is set to a length that overlaps with the leg 21b shown in FIG. 2 when the vehicle-mounted device 1 and the bracket 2 in the mounted state are viewed from the first direction. Note that the protrusion 33 illustrated here is U-shaped with an opening downward, but its shape is not particularly limited, and it is sufficient that it has at least a portion that interferes with each leg 21b in a state other than the mounted state.

A connection portion 34 is provided on the second side surface portion 31b (see FIG. 1), which forms the surface of the housing portion 31 facing one side in the first direction. The connection portion 34 is a portion that forms the location where the connector 4 is connected. As shown in FIGS. 3 to 5, the connection portion 34 has a through hole 34h that penetrates the second side surface portion 31b, a substantially rectangular cylindrical tube portion 34f that protrudes from the second side surface portion 31b and surrounds the through hole 34h, and a pair of long holes 34g that penetrate the second side surface portion 31b above and below the tube portion 34f. The long holes 34g extend in the second direction.

As described above, the three fitting portions 32 are portions into which the insertion pieces 22 of the bracket 2 are inserted from below and fitted, and are provided on the upper portion of the main body component 3. In this embodiment, the three fitting portions 32 are provided on the upper portion of the first side portion 31a. In other words, the first side portion 31a is a portion that extends below the three fitting portions 32. As shown in Figures 3 and 4, the three fitting portions 32 are arranged side by side and spaced apart from each other in the first direction, and open downward.

In this embodiment, the three mating portions 32 are also open upward, but these openings are not essential and may be omitted. Furthermore, the mating portions 32 located on both sides in the first direction (hereinafter referred to as "first mating portions 32A") of the three mating portions 32 are also open on the other side in the second direction, but these openings are not essential and may be omitted. Furthermore, the mating portion 32 located in the middle in the first direction (hereinafter referred to as "second mating portion 32B") of the three mating portions 32 is also open on one side in the second direction as shown in FIG. 1, but this opening is not essential and may be omitted.

In detail, as shown in FIG. 4, each fitting portion 32 has two opposing flat surfaces 32a, 32b that form an inner surface facing the second direction, a side surface 32c that connects both side edges of the flat surfaces 32a, 32b in the first direction, and a top surface 32d that connects the upper edges of the flat surfaces 32a, 32b. The two flat surfaces 32a, 32b are spaced apart from each other in the second direction. In this embodiment, the first flat surface 32a that faces the other side of the second direction of the two flat surfaces 32a, 32b is approximately flush with the first side surface 31a. The second flat surface 32b that faces one side of the second direction is located on the other side of the second direction than the first flat surface 32a. The insert piece 22 is inserted between the two flat surfaces 32a, 32b and faces each flat surface 32a, 32b in the attached state. The second flat surface portion 32b of the first fitting portion 32A has the above-mentioned opening formed in the vertical direction, dividing the second flat surface portion 32b in two in the first direction.

In addition to the above-mentioned portions 32a to 32d, the two first fitting portions 32A are provided with a rib 32r. The rib 32r is a portion formed by bulging out from the first flat portion 32a of the first fitting portion 32A, and in the attached state, it abuts against the insertion piece 22 that fits into the first fitting portion 32A, pressing the insertion piece 22 against the second flat portion 32b. As shown in FIG. 3, the rib 32r may be provided extending in the up-down direction in the central portion of the first flat portion 32a in the first direction.

The second fitting portion 32B is provided with a claw portion 32p as shown in Figs. 1 and 4. As shown in Fig. 1, the claw portion 32p engages with the engagement hole 22h of the insertion piece 22 that fits into the second fitting portion 32B in the attached state. In this embodiment, the claw portion 32p is provided on the second flat portion 32b of the second fitting portion 32B as shown in Fig. 4. More specifically, the claw portion 32p protrudes from the elastic piece portion 32q (see Fig. 3) of the second flat portion 32b toward one side in the second direction. The elastic piece portion 32q is a region defined by a pair of slits that extend in the vertical direction from the upper edge of the second flat portion 32b of the second fitting portion 32B. The slits do not extend to the lower end of the second flat portion 32b.

As shown in Figures 1 and 5, the connector 4 is a cable (e.g., an HDMI (registered trademark) (High-Definition Multimedia Interface) cable) having a male terminal 4a and a female terminal 4b at both ends. The female terminal 4b is disposed, for example, on the instrument panel so as to be exposed inside the vehicle cabin.

As shown in FIG. 5, the male terminal 4a is connected to the connection portion 34 of the main body component 3. More specifically, the male terminal 4a is inserted into the through hole 34h of the connection portion 34 from one side in the first direction and is connected to the electronic component of the main body component 3. Hereinafter, the state in which the connector 4 and the connector cover 5 are assembled to the main body component 3 is referred to as the assembled state, and unless otherwise specified, the description will be given assuming that they are in the assembled state.

The connector 4 is provided with a protective portion 4c that coats one side portion of the male terminal 4a in the first direction. The protective portion 4c is a portion that restricts the male terminal 4a from moving in the other direction in the first direction, has an outer shape that cannot be fitted into the through hole 34h of the connection portion 34, and abuts against the second side portion 31b. In this embodiment, the protective portion 4c is fitted into the tubular portion 34f. In addition, the protective portion 4c in this embodiment has a tapered shape in which the outer circumferential length decreases toward one side in the first direction.

As described above, the connector cover 5 is a part that covers the connector 4. The connector cover 5 has a cover portion 51 and an engagement portion 52. The connector cover 5 of this embodiment further has a protective wall portion 53.

The cover portion 51 has an inner peripheral surface 51f capable of housing the protective portion 4c of the connector 4 on the inside thereof, and is fitted onto the tubular portion 34f of the connection portion 34. As shown in FIG. 1, for example, the cover portion 51 has a C-shaped cross section in which a portion of the surface portion facing one side of the second direction is cut out along the first direction. As shown in FIG. 5, the inner peripheral surface 51f of the cover portion 51 has a tapered shape in which the inner peripheral length decreases toward one side of the first direction, corresponding to the shape of the protective portion 4c described above. The movement of the protective portion 4c of the connector 4 in one of the first directions (i.e., the direction of removal from the main body component 3) is restricted by this inner peripheral surface 51f.

As shown in FIG. 1, the engagement portion 52 is provided on the surface of the cover portion 51 facing the up-down direction, and is a portion partitioned by two slits. The upper engagement portion 52 can be elastically deformed by being pressed downward, and the lower engagement portion 52 can also be elastically deformed by being pressed upward. As shown in FIG. 5, the portion of the engagement portion 52 that extends further to the other side in the first direction than the cover portion 51 is inserted into the long hole 34g of the connection portion 34. This inserted portion, i.e., the other end of the engagement portion 52 in the first direction, is provided with a claw that protrudes upward and downward. The engagement portion 52 is inserted into the long hole 34g in a pressed and elastically deformed state, and then returns to its original state when the pressure is removed, and the claw hooks on the second side portion 31b, thereby restricting the connector cover 5 from moving in one direction in the first direction.

The protective wall portion 53 is a surface portion extending from one side of the cover portion 51 in the first direction. As shown in FIG. 1, the protective wall portion 53 is located between the connector 4 and the bracket 2 in the second direction in the attached and assembled state. This prevents the connector 4 and the bracket 2 from coming into contact in the attached and assembled state.

[2. Actions and Effects]
(1) The mounting of the in-vehicle device 1 to the bracket 2 is completed by fitting the insertion pieces 22 of the bracket 2 one by one from below into each of the three fitting portions 32 provided on the upper portion of the in-vehicle device 1. In this way, when the in-vehicle device 1 is fixed at its upper portion, in other words, at a position shifted from the center of gravity of the in-vehicle device 1, the fixing strength is likely to decrease and fluttering may occur. However, according to the above-mentioned mounting structure, the in-vehicle device 1 is fixed to the bracket 2 at three points of the three fitting portions 32, so that the fixing strength of the in-vehicle device 1 can be improved and fluttering can be suppressed.

In addition, in the above-mentioned mounting structure, three or more insertion pieces 22 of the bracket 2 are arranged in parallel and spaced apart from each other in the first direction. Therefore, each insertion piece 22 can be used as a portion for mounting a component other than the vehicle-mounted device 1. This improves the versatility of the bracket 2. For example, if five insertion pieces 22 are provided on the bracket 2 as described above, the insertion pieces 22 other than the regular insertion piece 22R can be used as a portion for fixing a relay component R of the vehicle-mounted cable C other than the connector 4, as shown in FIG. 2.

(2) In the mounted state, the insertion piece 22 that fits into the first fitting portion 32A is pressed against the second flat portion 32b by the rib 32r. In the above-described mounting structure, the insertion piece 22 can be fixed by being pressed by the rib 32r in this way, so that the fixing of the in-vehicle device 1 to the bracket 2 can be more stable and the flapping of the in-vehicle device 1 can be further suppressed.

(3) In addition, in the mounted state, the claw portion 32p of the second fitting portion 32B engages with the engagement hole 22h of the insertion piece 22 that fits into the second fitting portion 32B. In the above-described mounting structure, the claw portion 32p engages with the engagement hole 22h in this way, thereby restricting the vertical movement of the in-vehicle device 1. Therefore, the vertical position of the in-vehicle device 1 relative to the bracket 2 can be stably fixed. Furthermore, in this embodiment, the elastic piece portion 32q on which the claw portion 32p is provided is elastically deformable with its lower end as the base end, so that the insertion of the insertion piece 22 is not hindered by the claw portion 32p. Therefore, the insertion piece 22 can be smoothly inserted, improving the workability when fixing the in-vehicle device 1.

(4) A protrusion 33 is provided on the first side surface portion 31a of the main body component 3. This protrusion 33 is located between the two legs 21b in the attached state, and is provided in a position where it interferes with the legs 21b in other than the attached state. This prevents an insertion piece 22 other than the correct insertion piece 22R from fitting into the three fitting portions 32, thereby preventing incorrect assembly. In particular, when four or more insertion pieces 22 are provided, the possibility of incorrect assembly increases, so it is necessary to carefully check the attachment destination. However, if an attempt is made to assemble it into an incorrect attachment destination, the protrusion 33 and the legs 21b will interfere with each other, making assembly impossible in the first place, so incorrect assembly can be easily prevented and workability can be improved.

(5) The assembly of the components 3 to 5 of the in-vehicle device 1 is completed by inserting the male terminal 4a of the connector 4 into the through hole 34h of the connection portion 34 of the main body component 3 and inserting the engagement portion 52 of the connector cover 5 into the long hole 34g of the connection portion 34. At this time, the connector cover 5 is restricted from moving in one direction in the first direction by the claws of the engagement portion 52 engaging with the main body component 3. The protective portion 4c is restricted from moving in one direction in the first direction by the inner surface 51f of the cover portion 51 of the connector cover 5. As a result, the male terminal 4a of the connector 4 is restricted from moving in one direction in the first direction (i.e., the direction in which the connector 4 comes out of the main body component 3). Therefore, the male terminal 4a of the connector 4 can be prevented from coming out of the main body component 3 due to vehicle vibration, etc. In addition, according to the above-mentioned mounting structure, the in-vehicle device 1 including multiple components 3 to 5 can be assembled as a single assembly component, so that the multiple components 3 to 5 can be attached to the bracket 2 together. This makes it easy to attach the vehicle-mounted device 1 to the bracket 2.

[3. Other]
The above-described mounting structure is one example. The in-vehicle device 1 does not have to be one in which the main body part 3, the connector 4, and the connector cable 5 are assembled into a single part. For example, the in-vehicle device 1 may be one that is composed of the main body part 3 alone. That is, the connector 4 and the connector cover 5 may be omitted in the in-vehicle device 1. The in-vehicle device 1 does not have to be a signal conversion device disposed on the back side of the instrument panel. Furthermore, the in-vehicle device 1 does not have to be an electronic device. The bracket 2 need only be a bracket that is fixed at least to the vehicle, and does not have to be mounted on a gatepost bracket.

The direction (one direction) in which the insertion pieces 22 of the bracket 2 are arranged side by side does not have to be a direction that coincides with the vertical direction, and does not have to be a direction perpendicular to the vertical direction. In this case, the three fitting portions 32 only need to be arranged side by side and spaced apart from each other in the one direction in which the insertion pieces 22 are arranged side by side. Each insertion piece 22 only needs to extend upward from the base 21 at least, and the plate thickness direction of each insertion piece 22 is not limited to the second direction.

In the in-vehicle device 1, the protrusion 33 may be omitted. In this case, the leg 21b of the bracket 2 may be omitted. If the leg 21b of the bracket 2 is omitted, the fixing part 21c may be connected to the connecting part 21a, for example, or the connecting part 21a may be made into a large rectangular shape, and the function of the fixing part 21c may be given to the connecting part 21a, and the fixing part 21c may be omitted.

The mounting structure may be such that the in-vehicle device 1 is fixed to the bracket 2 by fitting the insertion pieces 22 one by one into each of the fitting portions 32, and the method of fixing the in-vehicle device 1 to the bracket 2 is not limited to the above. For example, the mounting structure may be such that the in-vehicle device 1 is fixed to the bracket 2 by pressing the insertion pieces 22 into the fitting portions 32. In this case, the rib 32r provided on the first fitting portion 32A may be omitted, and the claw portion 32p provided on the second fitting portion 32B may be omitted. Also, a portion such as the rib 32r of the first fitting portion 32A may be provided on the second fitting portion 32B, and a portion such as the claw portion of the second fitting portion 32B may be provided on the first fitting portion 32A.
