  In-vehicle electrical components include not only radar but also cameras. Furthermore, an electrical component in which a radar and a camera are integrated is also included. These electrical components acquire an external scene in front of the vehicle during driving and position information of an object included therein, and provide the driver with information for safe driving. In addition to this, other electrical components have a function of controlling automatic operation for avoiding danger. These electrical components are usually installed on the rear surface of the windshield of the vehicle or in the vicinity thereof in order to image a scene in front of the vehicle. In this case, the position information of the object included in the external scene is obtained based on the mounting position of the electrical component in the vehicle. Therefore, in order to accurately determine whether the vehicle operation is safe with this electrical component, it is essential that the vehicle mounting position of this electrical component does not change. In particular, the deviation of the optical axis of a camera or the like greatly affects the detection of the position of an object included in the external scene. On the other hand, when the passenger gets in and out of the passenger compartment, a part of the body or belongings may come into contact with the electrical equipment and collide. At that time, the mounting position of the electrical components must not change. If the position changes, the optical axis or radio wave transmission axis may change in the camera or radar. As a result, the position information regarding the scene in front of the vehicle is greatly shifted with respect to the vehicle. As a result, there is a case where it cannot be correctly determined whether or not the object included in the scene information collides with the vehicle.

  Therefore, when mounting an in-vehicle electrical component on a vehicle, it is required that the electrical component mounting position does not change even if there is contact or collision with an occupant or the like. Furthermore, such a fixture should have a simple structure in order to reduce manufacturing costs. Specifically, it is desirable that the fixture has a small number of springs and elastic members used.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a mounting device in which the mounting position of an electrical component does not change even when there is contact with an occupant or the like and the mounting structure is simple. To do.

  In order to solve the above-mentioned problem, an attachment according to the present invention is an attachment for attaching an in-vehicle electrical component on which at least one of a camera or a radar is mounted to a vehicle having a windshield, The vehicle-side attachment portion includes a vehicle-side attachment portion and an electrical component-side attachment portion, and the vehicle-side attachment portion has at least a rail receiver extending in a first direction and an elastic portion, and the elastic portion is in the first direction. A first pressing portion (bending portion) that generates a first pressing force; and a second pressing portion (hanging portion) that generates a second pressing force in a second direction different from the first direction. The side attachment portion includes a rail extending in the first direction, a first pressure-receiving portion that faces the first pressing portion and receives at least a part of the first pressing force, and faces the second pressing portion. Second pressed part that receives at least part of the second pressing force The vehicle side mounting portion includes a first receiving portion that receives at least a part of the pressing force of the first pressing portion via the first pressure receiving portion, and the second pressure receiving portion. And a second receiving part for receiving at least a part of the pressing force of the second pressing part, and the rail receiver of the vehicle side mounting part is configured by the first pressing force and the second pressing force, A fixture fixed in combination with the rail of the electrical component side mounting portion.

  Here, the on-vehicle electrical components are devices including various electronic control units (ECUs), such as on-vehicle obstacle detection devices such as millimeter wave radars, laser radars, and cameras, and wiper devices. Sensors such as a rain sensor for automatically controlling and a solar radiation sensor for automatically controlling an air conditioner.

  According to this configuration, when the fitting is pushed from the lower side to the upper side against the elastic force of the elastic part, the elastic part is elastically deformed and attached to the electric part side. The parts are received and engaged by reaching the attachment position, and the electric component side attachment part is pressed against the first contact surface and the second contact surface by the elastic part and supported at the attachment position.

  According to the present invention, since the number of parts to be used is smaller than that of the conventional mounting structure, the manufacturing cost is low. In addition to the mounting direction of the mounting fixture, the electrical component side mounting part applies a pressing force in a direction different from this direction, and is fixed so that there is no backlash.

≪Mounting device for in-vehicle electrical components according to the embodiment≫
As shown in FIG. 1, the fixture 1 is configured by combining an electrical component side mounting portion 10 and a vehicle side mounting portion 20. This mounting tool 1 is used for mounting the on-vehicle electrical component 2 on the windshield of the vehicle or on the side of the passenger compartment in the vicinity thereof. Here, the vehicle-mounted electrical component 2 is a device including various electronic control units (ECUs), for example, a vehicle-mounted obstacle detection device such as a millimeter wave radar, a laser radar, or a camera, or a wiper device. Sensors such as a rain sensor for controlling the solar radiation and a solar radiation sensor for controlling the air conditioner device. In the present embodiment, as shown in FIG. 2, a composite sensor including a millimeter wave radar 2 a and a camera 2 b in a housing 2 c is assumed as the in-vehicle electrical component 2. The in-vehicle electrical component 2 is a fixture in which the emission direction of radio waves (arrow α in FIG. 2) in the millimeter wave radar 2a and the imaging direction of the camera 2b (arrow β in FIG. 2) are directed in the traveling direction (front) of the vehicle. 1 is fixed.

<Electrical component side mounting part>
As shown in FIG. 3, there is a convex electrical component side mounting portion 10 attached to the vehicle side mounting portion 20 at the upper rear of the housing 2 c of the in-vehicle electrical component 2. The electrical component side mounting portion 10 may have an integrally molded structure configured in a state of being continuous with the same material as the casing 2c, or may be configured as a separate member from the casing 2c and joined to each other. In the present embodiment, it is assumed that the electrical component side mounting portion 10 and the housing 2c are configured as separate members and joined. Below, the electrical component side attachment part 10 will be described first, and then the attachment 1 will be described.

  As shown in FIG. 4, the electrical component side mounting portion 10 is disposed on the upper surface of the in-vehicle electrical component 2 and has a convex shape upward. The electrical component side mounting portion 10 has a shape in which the upper surface 11 is inclined. Here, the upper surface 11 is inclined with respect to the lower surface 12 by an angle θ (°). The inclination angle θ should correspond to the inclination angle of the windshield of the vehicle. That is, the inclination angle θ should be appropriately selected according to the inclination angle of the windshield of the vehicle to be attached. In general, the inclination angle of the windshield of a vehicle varies depending on the vehicle type and vehicle manufacturer. By preparing an electrical component side attachment portion having an inclination corresponding to each inclination angle in advance and selecting and using it at the time of attachment, the electrical component can be installed at a predetermined angle regardless of the vehicle type. Further, as shown in FIG. 5, the front surface 13 and the rear surface 14 of the electrical component side mounting portion 10 are orthogonal to the upper surface 11 (see FIG. 5).

  The electrical component mounting portion 10 generates a second pressing force by elastic deformation of the elastic portion 30 at the mounting position of the vehicle side mounting portion 20, and the hanging portion 32 (second pressing portion) is the rear surface 14 (second pressed portion). The front surface 13 is formed in a shape corresponding to the vehicle-side mounting portion 20 so as to press the inner surface 22aa (second receiving portion) of the front wall 22a of the vehicle-side mounting portion 20 by the pressing force. That is, the length of the upper surface 11 in the front-rear direction is formed to be slightly larger than the distance from the front wall 22 a of the vehicle-side mounting portion 20 to the hanging portion 32 of the elastic portion 30. Thereby, in the attachment position of the vehicle side attachment part 20, the front surface 13 contact | abuts to inner surface 22aa of the front wall 22a, and the rear surface 14 contact | abuts to the hanging part 32 of the elastic part 30 (refer FIG. 7). Here, there is a gap between the front surface of the rail 16 and the rail receiver 23, and the front surface 13 of the electrical component mounting portion 10 first comes into contact with the inner surface 22aa of the front wall 22a by the second pressing force. It is said. Further, the length of the upper surface 11 in the left-right direction is preferably formed to be equal to the distance between the rail receivers 23, 23 of the vehicle-side mounting portion 20. Thereby, in the attachment position of the vehicle side attaching part 20, both the side surfaces 15 and 15 contact | abut to the rail receivers 23 and 23 (refer FIG. 7).

  As shown in FIG. 4, rails 16, 16 are formed on both the left and right side surfaces 15, 15 of the electrical component side mounting portion 10 so as to protrude laterally. This rail 16 is used to guide the mounting position when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20. The rail 16 is formed in a shape corresponding to a rail receiver 23 of the vehicle side mounting portion 20 described later. Here, the rail 16 has a vertically long shape, and is formed so that the central axis in the length direction is orthogonal to the upper surface 11 (parallel to the front surface 13 and the rear surface 14).

  Moreover, as shown in FIG. 5, the recessed part 17 is formed in the rear part of the electrical equipment side attaching part 10 toward the front. The concave portion 17 is engaged with the elastic portion 30 of the vehicle-side attachment portion 20 when attached to the vehicle-side attachment portion 20, and is formed in a shape corresponding to the elastic portion 30. Specifically, the concave portion 17 is formed so that the bent portion 33 of the elastic portion 30 abuts at least a part thereof. Here, the recess 17 includes a recess upper surface 17 a parallel to the upper surface 11 and a recess front surface 17 b parallel to the front surface 13, and from one side surface 15 to the other side surface 15 in the rear part of the electrical component side mounting portion 10. It is formed continuously (see FIG. 6). The distance from the upper surface 11 to the recess upper surface 17a is formed slightly larger than the vertical length of the hanging portion 32 of the elastic portion 30. By taking a certain distance from the upper surface 11 to the recess upper surface 17a, the length of the hanging portion 32 of the elastic portion 30 to be described later can be increased to facilitate elastic deformation. Further, the distance from the rear surface 14 to the concave front surface 17b is formed to be larger than the length in the front-rear direction of the bent portion 33 of the elastic portion 30 described later. By making the distance from the rear surface 14 to the concave front surface 17b larger than that of the bent portion 33, the bent portion 33 can be prevented from contacting the concave front surface 17b when the elastic portion 30 is engaged with the concave portion 17.

<Vehicle side mounting part>
Then, the structure of the vehicle side attaching part 20 is demonstrated. The vehicle side mounting portion 20 supports the electrical component side mounting portion 10 and fixes the in-vehicle electrical component 2 (see FIG. 2) to the windshield. As shown in FIG. 5, the vehicle side mounting portion 20 has an elastic portion 30.

  As shown in FIG. 6, the vehicle-side mounting portion 20 includes a plate-shaped top plate portion 21, a wall portion 22 formed in a range half of the outer peripheral edge of the top plate portion 21, and the outer peripheral edge of the top plate portion 21. In this case, a pair of rail receivers 23, 23 formed at both ends of the wall portion 22 are provided. The vehicle side mounting portion 20 is made of, for example, a synthetic resin, and the top plate portion 21, the wall portion 22, and the rail receiver 23 are integrally formed.

  The top plate portion 21 is a plate material having a rectangular shape (plan view) viewed from above (see FIG. 4). An adhesive sheet (not shown) is installed on the upper surface 21 a of the top plate portion 21, and is fixed to the passenger compartment side of the windshield using this adhesive sheet. Note that a paste or liquid adhesive may be applied to the upper surface 21a of the top plate portion 21 instead of the adhesive sheet. Further, when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20, the upper surface 11 of the electrical component side mounting portion 10 contacts the lower surface 21 b of the top plate portion 21. The lower surface 21b of the top plate portion 21 is a first contact surface.

  The wall portion 22 includes a front wall 22a that protrudes in a right-angle direction from the front of the lower surface 21b of the top plate portion 21, and side walls 22b and 22b that are respectively formed on the left and right sides of the lower surface 21b of the top plate portion 21 continuously to the front wall 22a. Consists of. When the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20, the front surface 13 of the electrical component side mounting portion 10 abuts on the inner surface 22aa of the front wall 22 a (see FIG. 7). An inner surface 22aa of the front wall 22a is a second contact surface. On the other hand, the inner surfaces 22ba of the side walls 22b are formed so that the side surface 15 of the electrical component side mounting portion 10 does not come into contact with the space when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20. (See FIG. 7). It is desirable that the height of the wall portion 22 be smaller than the height dimension of the front surface 13 of the electrical component side mounting portion 10. The height of the wall portion 22 is made smaller than the upper surface 11 of the electrical component side mounting portion 10 when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20 and the tip of the wall portion 22 is mounted on the vehicle. This is to prevent contact with the housing 2c (see FIG. 2) of the electrical component 2. In addition, the side walls 22b and 22b are formed up to half of the entire side length here. Therefore, the side walls 22b, 22b are not formed on the rear side of the rail receivers 23, 23.

  Both the rail receivers 23, 23 are formed continuously with the wall portion 22 at a substantially opposed position at the side center. A vertical groove 23 a (vertical groove) is formed inside each rail receiver 23. The vertical groove 23a is formed so that the shape (viewed from the bottom) seen from below forms a substantially U-shape (U-shape) (see FIG. 7). Both rail receivers 23, 23 come into contact with both side surfaces 15, 15 of the electrical component side mounting portion 10 when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20, and the vertical groove 23 a has the rail 16. , 16 to be fitted. That is, the distance between the rail receivers 23 and 23 should be equal to the lateral width of the electrical component side mounting portion 10, and the shape and depth of the vertical groove 23 a should be matched to the dimensions of the rails 16 and 16. . Thereby, the rail receivers 23 and 23 can guide the electrical component side mounting portion 10 to the mounting position.

  Moreover, it is desirable that the height of each rail receiver 23 is larger than the side wall 22b and smaller than the height of the central portion of the electrical component side mounting portion 10. The height of the rail receivers 23 and 23 is adjusted so that the electrical component side mounting portion 10 can be easily guided to the mounting position, and when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20, the rail receiver This is to prevent the tips of 23 and 23 from coming into contact with the housing 2c (see FIG. 2) of the in-vehicle electrical component 2.

<Elastic part>
The elastic portion 30 presses the electrical component side mounting portion 10 using a pressing force due to elastic deformation and engages with the concave portion 17 of the electrical component side mounting portion 10. In the present embodiment, a plate spring having a predetermined strength is assumed as the elastic portion 30. As shown in FIG. 5, the elastic portion 30 includes a joining portion 31 joined to the lower surface 21 b (first contact surface) of the top plate portion 21, and a hanging portion 32 formed by bending downward from the joining portion 31. The bent portion 33 is formed by bending forward from the drooping portion 32, and the end portion 34 extends further downward from the bent portion 33.

  The joint portion 31 is a portion joined to the top plate portion 21 and may be joined to the top plate portion 21 by any means. For example, the joining portion 31 and the top plate portion 21 may be joined using a paste-like or liquid adhesive, or may be joined using a screw or the like. The position where the joint portion 31 is joined to the top plate portion 21 is the attachment position of the vehicle-side attachment portion 20, and a second pressing force is generated by the elastic deformation of the elastic portion 30, and the hanging portion 32 (second pressing portion) is the rear surface 14. The second pressure-receiving portion is pressed, and the front surface 13 is brought into a position to press the inner surface 22aa (second receiving portion) of the front wall 22a of the vehicle-side mounting portion 20 by the pressing force. Here, the distance between the front wall 22a of the vehicle-side mounting portion 20 and the hanging portion 32 is slightly smaller than the dimension of the electrical component-side mounting portion 10 in the front-rear direction. Thereby, the drooping portion 32 (second pressing portion) abuts the rear surface 14 (second pressure-receiving portion) of the electrical component side mounting portion 10 at the mounting position, and the front portion due to elastic deformation with respect to the electrical component side mounting portion 10. Transmits the pressing force in the direction.

  The bent portion 33 abuts along at least a part of the concave portion 17 (here, the concave portion upper surface 17a (first pressure-receiving portion)) of the electrical component side attaching portion 10 at the attachment position. The (first pressing portion) generates an upward first pressing force by elastic deformation with respect to the electrical component side mounting portion 10. The first pressing force is received by the lower surface 21 b (first receiving portion) of the vehicle side mounting portion 20 through the upper surface 11 of the electrical component side mounting portion 10 and the joint portion 31 of the elastic portion 33. As a result, the positioning and fixing of the electrical component side mounting portion 10 in the vertical direction is realized. Here, the shape and dimensions of the bent portion 33 may be any as long as the electrical component side mounting portion 10 does not fall out of the vehicle side mounting portion 20 at the mounting position in consideration of the mass of the in-vehicle electrical component 10. Here, the bent portion 33 is substantially 90 ° with respect to the hanging portion 32. Note that the angle of the continuous portion 33a where the bent portion 33 and the end portion 34 are continuous should be moderate (approximately 30 ° to 60 °). The continuous portion 33a is for smoothly engaging the electrical component side mounting portion 10 with the bent portion 33 when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20 from below. The continuous portion 33a plays a role of a slide surface that abuts the corner portion of the electrical component side mounting portion 10 and elastically deforms the hanging portion 32 rearward.

  Moreover, when removing the electrical equipment side attachment part 10 from the vehicle side attachment part 20, the end part 34 is for a person to push the elastic part 30 back backward. The end portion 34 is preferably disposed at the rear or the same position as the hanging portion 32 in the vertical direction. By engaging the end portion 34 backward, the engagement between the bent portion 33 and the concave portion 17 is canceled. In this state, the electrical component side mounting portion 10 is detached from the vehicle side mounting portion 20 by moving the electrical component side mounting portion 10 downward.

≪Usage of the fixture according to the embodiment≫
With reference to FIG. 8, the attachment method of the vehicle-mounted electrical component 2 using the vehicle side attachment part 20 is demonstrated.

  First, a person who installs the in-vehicle electrical component 2 (hereinafter referred to as “installer”) places the fixture 1 at a predetermined position on the vehicle side of the windshield (for example, in front of the rearview mirror). Fix (see FIG. 8A). At this time, the direction of the fixture 1 is set so that the elastic portion 30 is rearward with respect to the traveling direction of the vehicle.

  Subsequently, the installer aligns the position of the rail 16 of the electrical component side mounting portion 10 with the vertical groove 23 a (see FIG. 6) of the rail receiver 23, and resists the elastic force of the elastic portion 30, so that the electrical component side mounting portion 10. Is pushed into the vehicle-side mounting portion 20 along the vertical groove 23a from below to above (see FIG. 8B). The vehicle-side mounting portion 20 receives the electrical component-side mounting portion 10 by elastically deforming the hanging portion 32 when the continuous portion 33a (see FIG. 5) of the elastic portion 30 is pressed, and moves the bent portion 33 rearward. .

  Further, when the electrical component side mounting portion 10 is pushed in until reaching the top plate portion 21 (see FIG. 6), the bent portion 33 of the elastic portion 30 moves forward so as to enter the concave portion 17 and engages with the concave portion 17. (See FIG. 8C). In the state shown in FIG. 8C, the hanging portion 32 presses the electrical component side mounting portion 10 forward, and the bent portion 33 presses the electrical component side mounting portion 10 upward. For this reason, even if vibration is generated as the vehicle travels, the in-vehicle electrical component 2 is firmly fixed to the vehicle-side mounting portion 20 and thus does not rattle.

  As described above, when the fixture 1 according to the embodiment pushes the electrical component side mounting portion 10 into the vehicle side mounting portion 20 from below to the upper side against the elastic force of the elastic portion 30, the elastic portion 30 is The electrical component side mounting portion 10 is elastically deformed and engaged by reaching the mounting position. The elastic portion 30 causes the electrical component side mounting portion 10 to be engaged with the lower surface 21b as the first contact surface and the second contact. The inner surface 22aa which is a surface is pressed and supported at the mounting position. Therefore, since the number of parts used is smaller than that of the conventional mounting structure, the manufacturing cost is low. In addition, since the electrical component side mounting portion 10 is in surface contact with the vehicle side mounting portion 20 at two locations and is pressed on each surface, there is no backlash between components.

  As described above, the fixture 1 according to the present embodiment includes the vehicle-side mounting portion 20 and the electrical component-side mounting portion 10, and the vehicle-side mounting portion 20 includes the rail receiver 23 extending in the first direction, and the elastic portion. 30, and the elastic part 30 has a second pressing force in a second direction different from the first direction, and a bent part 33 that is a first pressing part that generates a first pressing force in the first direction. The electrical component side mounting part 10 has a rail 16 extending in the first direction and at least part of the first pressing force facing the first pressing part. The first pressure-receiving portion 17a that receives the second pressure-receiving portion 14 that faces the second pressing portion and receives at least part of the second pressing force is provided. A first receiving part 21b for receiving at least part of the pressing force of the first pressing part via A second receiving part 22aa for receiving at least a part of the pressing force of the second pressing part via the pressure part, and the rail receiver 23 of the vehicle side mounting part 20 has a first pressing force and a second pressing force. The mounting fixture is fixed in combination with the rail 16 of the electrical component side mounting portion 10.

  In the above, the electrical component side mounting portion 10 has an upper surface 11 and a lower surface 12, and the lower surface 12 is inclined with respect to the upper surface 11 at an angle θ as shown in FIG. This inclination angle θ corresponds to the inclination angle of the windshield of the vehicle. Thereby, the vehicle-mounted electrical component 2 can be attached to the vehicle in a certain direction without depending on the inclination angle of the windshield. Usually, the inclination angle of the windshield of a vehicle varies depending on the vehicle manufacturer and vehicle type. Therefore, by preparing the electrical equipment-side mounting portion 10 having an inclination angle corresponding to each vehicle type and using it properly depending on the vehicle type, it is possible to provide a mounting device that takes into account the angles of a plurality of windshields.

≪Modification≫
As mentioned above, although embodiment of this invention was described, this invention is not limited to this, It can implement in the range which does not change the meaning of a claim. The modification of embodiment is shown below.

  As shown in FIG. 6, in the vehicle-side mounting portion 20 according to the embodiment, rails 16 are formed on both the left and right side surfaces 15, 15 of the electrical component-side mounting portion 10, and vertical grooves 23 a are respectively formed in the rail receivers 23, 23. Was formed. Here, the vertical groove 23 a is an engagement recess that engages with the rail 16. Thereby, it was possible to easily guide the electrical component side mounting portion 10 to the mounting position.

  However, as shown in FIG. 9, groove portions 16 </ b> A may be formed on both the left and right side surfaces 15, 15 of the electrical component side mounting portion 10, and the protrusion portions 23 </ b> A may be formed on the rail receivers 23, 23, respectively. Here, the protruding portion 23A is an engaging convex portion that engages with the groove portion 16A. Even in this case, it is possible to easily guide the electrical component side mounting portion 10 to the mounting position. In addition, the structure which does not comprise the rail receivers 23 and 23 may be sufficient as the vehicle side attaching part 20. FIG.

  Moreover, the rail and the rail receiver need only be able to smoothly insert the electrical-side mounting part 10 into the vehicle-side mounting part 20 and to determine the position after insertion. Or vice versa, the vehicle-side attachment portion can be smoothly inserted into the electrical equipment-side attachment, and the position after the insertion can be determined. Accordingly, other structures that realize these functions, for example, such rails and rail receivers are removed, and a part of the side peripheral surface of the electrical equipment side mounting part 10 and the wall part 22 provided on the side peripheral side of the vehicle side mounting part 20 are provided. A case where a part of the inner periphery of each other meshes with each other to realize a function equivalent to that of the rail and the rail receiver is also included in the present invention.

  Moreover, in embodiment, although the material of the fixture 1 was not specifically limited, it is good to use the material (for example, metals, such as aluminum and copper) with a heat dissipation effect. Thereby, the heat which generate | occur | produces in the vehicle-mounted electrical component 2 can be escaped efficiently outside. For example, the vehicle-side mounting portion 20 may be cast from aluminum or the like, or may include at least one of the surface (the lower surface 21b that is the first contact surface and the inner surface 22aa that is the second contact surface) after resin molding. ) May be produced by plating. As a result, the heat generated in the in-vehicle electrical component 2 is radiated into the air from the in-vehicle electrical component 2 and the vehicle-side mounting portion 20, and is also transmitted to the windshield via the vehicle-side mounting portion 20. The heat is dissipated in the air.

  In the embodiment of the present invention described above, the first pressing force in the rail direction and the second pressing force in the direction different from this and the processing accuracy of the mounting tool 1 realize mounting without mounting of the on-vehicle electrical components. ing. Here, the processing accuracy of the fixture 1 is the processing accuracy of the vehicle-side mounting portion 20 rail and rail receiver, or the wall portion 22 formed in the range of half the outer peripheral edge of the top plate portion 21 of the vehicle-side mounting portion 20 and this. This is realized by increasing the processing accuracy with the side wall portions (13, 14, etc.) of the electrical component side mounting portion 10 facing the surface.

  FIG. 10 shows another embodiment in which the shape of the elastic portion 30 and the shape of the electrical component side mounting portion 10 facing this are different. In FIG. 10, the numbers of the parts added in this other embodiment are attached to the center, and the other parts are the same as the shapes and numbers described in FIGS. 1 to 9, and thus the numbers are omitted. . In this other embodiment, three pressing portions of the elastic portion 30 are provided, and in addition to the first pressing force in the rail direction and the second pressing force in a different direction, a third pressing force in a direction different from these directions is used. A third pressing part for generating pressure is further provided. These three-direction pressing forces press the electrical component-side mounting portion 10 from three directions, thereby realizing mounting without mounting of the vehicle-mounted electrical component.

  The fixture 1 according to another embodiment includes a vehicle-side mounting portion 20 and an electrical component-side mounting portion 10, and the vehicle-side mounting portion 20 includes a rail receiver 23 extending in a first direction, an elastic portion 30, and the like. The elastic portion 30 generates a second pressing force in a second direction different from the first direction, and a bent portion 33 that is a first pressing portion that generates the first pressing force in the first direction. The hanging part 32 that is the second pressing part, and a third pressing part 321 that generates a third pressing force in a third direction different from the first direction and the second direction, and the electrical component side mounting part 10 Includes a rail 16 extending in the first direction, a first pressed portion 17a facing the first pressing portion and receiving at least a part of the first pressing force, and at least a second pressing force facing the second pressing portion. The second pressed part 14 that receives a part, and the third pressing part facing the third pressing part A first receiving portion 21b for receiving at least a part of the pressing force of the first pressing portion via the first pressed portion. A second receiving portion 22aa for receiving at least a part of the pressing force of the second pressing portion via the second pressed portion, and at least a portion of the pressing force of the third pressing portion via the third pressed portion. 3rd receiving part 22aa which receives, and the 3rd direction is a direction which is not on the 1st virtual plane formed by the 1st direction and the 2nd direction, and rail of vehicle side attaching part 20 The receiver 23 is a fixture that is fixed in combination with the rail of the electrical component side attachment portion by the first pressing force, the second pressing force, and the third pressing force.

  In the above, the electrical component side mounting portion 10 has an upper surface 11 and a lower surface 12, and the lower surface 12 is inclined with respect to the upper surface 11 at an angle θ as shown in FIG. This inclination angle θ corresponds to the inclination angle of the windshield of the vehicle. Thereby, the vehicle-mounted electrical component 2 can be attached to the vehicle in a certain direction without depending on the inclination angle of the windshield. Usually, the inclination angle of the windshield of a vehicle varies depending on the vehicle manufacturer and vehicle type. Therefore, by preparing the electrical equipment-side mounting portion 10 having an inclination angle corresponding to each vehicle type and using it properly depending on the vehicle type, it is possible to provide a mounting device that takes into account the angles of a plurality of windshields.

  Next, a third embodiment which is another modification will be described with reference to FIG. In the third embodiment, the elastic portion 30 has a structure shown in FIG. The left rail and rail receiver, which is one of the other rail and rail receiver, have convex portions in the left-right direction. When this combines the vehicle-side mounting portion 20 and the electrical component-side mounting portion 10, pressure is generated in the left-right direction to prevent backlash in the left-right direction. The right rail and the rail receiver do not need to have such irregularities, and in this perspective view, it has the same structure as the first embodiment.

  FIG. 11A shows a plan view corresponding to FIG. 7 of the first embodiment, which is the third embodiment. FIG. 11B shows a cross-sectional view of the X-X ′ cross section viewed from the front, and FIG. 11C shows a cross-sectional view of only the left rail portion of the electrical component side mounting portion 10. A convex portion 233 protruding in the right direction is provided at an intermediate portion in the vertical direction of the rail receiver 23. The height of the convex portion 233 takes into account the gap in the left-right direction between the vehicle-side mounting portion 20 and the electrical component-side mounting portion 10 and the elasticity of these materials, and prevents backlash of these gaps during combination. In addition, even when an external impact force is applied, it has a dimension that generates an elastic force that does not shift. This convex part 233 comprises a part of elastic part of this invention. The elastic force generated here generates a third pressing force and pushes the rail portion 16 of the electrical component side mounting portion 10. Therefore, the rail part 16 becomes a third pressed part. The third pressing force is received by the left inner surface 23a of the right rail receiver in FIG. And this inner surface 23a becomes a 3rd receiving part. By adopting such a structure, the elastic portion 321 or 322 by the spring that generates the third pressing force shown in FIG. 10 is not necessary. Accordingly, it is possible to realize a fixture in which the structure of the elastic portion 30 is simplified compared to the embodiment of FIG.

  In the third embodiment, as shown in FIGS. 11 (b) and 11 (c), a convex portion 166 protruding leftward is provided below the rail portion 16. The convex portion 166 is positioned below the convex portion 233 of the left rail receiver 23 in a state where the vehicle side mounting portion 20 and the electrical component side mounting portion 10 are combined, and has a structure of meshing. By this meshing, the convex portion 166 has a function of preventing the electrical component side mounting portion 10 from coming off. Thereby, the retaining action of the bent portion 33 of the elastic portion 30 can be reinforced.

As described above, the vehicle-side attachment portion 20 of the attachment portion 1 can be attached to the vehicle interior side of the vehicle windshield or the vehicle interior. In this vehicle, the on-vehicle electrical component 2 can be fixed at a predetermined position in the passenger compartment without any backlash, and the driver support function provided therein can be reliably executed. Moreover, the electrical equipment side attaching part 10 of the inclination angle corresponding to each vehicle type is prepared, and the fixture which considered the angle of several windshields can be provided by using properly according to a vehicle type.
