Description

The present invention relates to electronic devices.

Patent document 1 describes a structure in which a drive recorder device (mounting member) is attached to the inner surface of a vehicle's windshield (receiving member) using double-sided tape.

JP 2018-114878 A

The structure described in Patent Document 1 is such that the drive recorder device has a relatively large recorder body, which is attached to the windshield via a movable arm, a fixed arm, and an attachment plate, and by double-sided tape affixed to the attachment plate.
That is, the recorder body is located far from the windshield, and a moment is applied to the double-sided tape, particularly to the upper portion, in a direction that causes it to be peeled off from the windshield.

As a result, when a drive recorder device is attached to a windshield, there is a possibility that over time, part of the double-sided tape, which serves as the adhesive material, may peel off from the windshield or the attachment plate, causing the attachment state of the drive recorder device to become unstable. For this reason, there is a need for a way to maintain the attachment state stably for a long period of time.

The problem that this invention aims to solve is to provide an electronic device whose installation state can be stably maintained for a long period of time.

In order to solve the above problems, the present invention has the following configuration.
The electronic device comprises a main body portion, an attachment portion supported by the main body portion and attached to a receiving member having a concave surface via an adhesive member capable of being elastically compressed, and a plurality of support portions that apply the gravity acting on the main body portion to the attachment portion when the attachment portion is positioned above the main body portion, and at least one of the plurality of support portions is located on the periphery of the attachment portion where the degree of compression of the adhesive member becomes high.

The present invention has the effect of maintaining the installation state stably for a long period of time.

(Example)
Fig. 1 is a left side view, partially in section, showing a state in which a drive recorder 51 is attached to the inner surface 3a of a vehicle's windshield 3. In Fig. 1, the front-rear and up-down directions of the vehicle are indicated by arrows. The left side is the front side of the page, and the right side is the back side of the page. In addition, the outward-inward directions perpendicular to the upper surface 123 of the mounting plate 12 are respectively defined as the Y-front direction and the Y-rear direction, and the up-down directions perpendicular to the Y-front-Y-rear direction are defined as the Y-upward direction and the Y-downward direction, and are indicated by arrows.
FIG. 1 illustrates the windshield 3, which is a curved, non-flat member, as a flat member for convenience.

The drive recorder 51 has a main body 1, a mounting plate 12, a link arm 14, and a cable 13. The exterior of the main body 1, the mounting plate 12, and the link arm 14 are made of resin or metal.

The main body 1 is formed in a rectangular parallelepiped shape that is thin in the vertical direction, and has a camera unit 11, a signal processing unit 19, and a memory unit 20. The main body 1 is used in a position in which the camera unit 11 is located in front of the windshield 3. The lens unit 11a of the camera unit 11 is exposed on the front surface of the main body 1. The signal processing unit 19 and the memory unit 20 are housed within the main body 1.

A mounting plate support portion 16 is formed on the front portion of the upper surface of the main body portion 1. The mounting plate support portion 16 supports a lower end portion Y of the mounting plate 12 so as to be rotatable about a rotation axis line CL16 extending in the left-right direction.
A plate-shaped link guide 15 is provided upright on the rear top surface of the main body 1. The link guide 15 has an elongated hole 151 extending in a direction along the optical axis CL11 of the camera unit 11.

The mounting plate 12 has an adhesive member 2 adhered to an upper surface 123, which is the side opposite to the main body 1. The adhesive member 2 is, for example, a double-sided tape that is elastically compressible in the thickness direction. The upper surface 123 is also the mounting surface for the adhesive member 2, and the mounting plate 12 having the upper surface 123 serves as a mounting part for mounting the drive recorder 51 to the inner surface of a windshield that is curved so that the inner surface is concave.
One end of the lead wire 13 a is connected to the signal processing unit 19 , and the other end is pulled upward from the main body 1 and along the mounting plate 12 to be pulled out from the rear surface 124 as the cable 13 .

The cable 13 includes a power supply line that supplies power to the camera unit 11 and the signal processing unit 19, and a signal line that transmits to the outside the video signal output from the camera unit 11 and the signal of the image captured by the camera unit 11 and stored in the memory unit 20.
After being pulled out from the rear surface 124, the cable 13 is routed around the rearview mirror above the center of the windshield 3 and connected to a monitor device (not shown) such as a car navigation system installed in the vehicle.

The surface of the mounting plate 12 on the side of the main body 1 is a lower surface 125. A link arm support portion 17 is provided at or near the end of the lower surface 125 on the rear surface 124 side.
The link arm support portion 17 supports one end of the link arm 14 so as to be rotatable about a rotation axis CL17 extending in the left-right direction.
The other end of the link arm 14 is connected to the main body 1 as a slider portion 18. The slider portion 18 is a connection portion where the link arm 14 engages with the elongated hole 151 of the link guide 15 so as to be slidable in the direction of the optical axis CL11 (see arrow DRb).
The slider portion 18 has a locking function, and is capable of locking the engagement position of the link arm 14 with respect to the link guide 15 at a desired front-rear position within the elongated hole 151 .

The drive recorder 51 is attached to the windshield 3 by adhering (sticking) the double-sided tape 2 adhered to the mounting plate 12 to the inner surface 3 a of the windshield 3 .
In the drive recorder 51, the locking position of the slider portion 18 can be adjusted in the front-rear direction, so that the erect angle of the mounting plate 12 connected by the link arm 14 relative to the main body portion 1 can be freely set.

The rising angle is an angle with respect to the horizontal plane LH. For example, in FIG. 1, the slider portion 18 is located at the front end of the long hole 151, and the rising angle is angle θ1.
As a result, when the drive recorder 51 is attached to the inner surface 3a of the windshield 3, the imaging range of the area in front of the vehicle captured by the camera unit 11 through the windshield 3 can be adjusted in the vertical direction according to the inclination angle of the inner surface 3a.

FIG. 2 is a front view of the drive recorder 51. FIG.
2, the mounting plate support portion 16 has a pair of protrusions 11b1, 11b2 that protrude upward and are spaced apart from each other on the left and right sides at the front of the main body 1, and a support shaft portion 11c that extends in the left-right direction and is provided to connect the pair of protrusions 11b1, 11b2. The support shaft portion 11c is formed with the rotation axis line CL16 as its axis.

The mounting plate 12 has a hook portion 12c at a front end (lower end in the Y direction). More specifically, the mounting plate 12 has a pair of hook portions 12c1, 12c2 at both left and right ends that slidably and rotatably engage with the circumferential surface of the support shaft portion 11c.
That is, the mounting plate support portion 16 is divided into a mounting plate support portion 161 in which the hook portion 12c1 is engaged with the support shaft portion 11c, and a mounting plate support portion 162 in which the hook portion 12c2 is engaged with the support shaft portion 11c.

The distance between the outer surfaces of the hook portions 12c1, 12c2 in the left-right direction is set to be slightly smaller than the distance between the inner surfaces of the pair of protrusions 11b1, 11b2 in the left-right direction, so that the mounting plate 12 is in a state where there is essentially no left-right movement when rotating about the rotation axis CL16.

Next, the structures of the link arm 14, the link arm support portion 17, and the slider portion 18 will be described with reference mainly to FIG. 3 and FIG.
3 is a rear view of the drive recorder 51, and FIG. 4 is a cross-sectional view taken along the line S4-S4 in FIG.
As shown in FIG. 3, a plurality of operation buttons 11s for operating the drive recorder 51 are arranged on the rear surface of the main body 1 as an operation section 11sG.

The link arm 14 has a plate-shaped base 14a, a sliding support portion 14b that protrudes cylindrically on the slider portion 18 side with a rotation axis CL18 that extends in the left-right direction perpendicular to the base 14a, and a rotation support portion 14c that is formed with a thinner thickness on the link arm support portion 17 side.
A recess 14b1 is formed on the opposite side of the sliding support portion 14b in the link arm 14. A through hole 14b2 having an axis corresponding to a rotation axis CL18 is formed in the sliding support portion 14b. Furthermore, a through hole 14c1 having an axis corresponding to a rotation axis CL17 extending in the left-right direction is formed in the rotation support portion 14c.

In the link arm support portion 17, the mounting plate 12 has a support wall 12d and a recess 12d1 formed in the support wall 12d. A through hole 12d2 having an axis coincident with the rotation axis line CL17 is formed in the recess 12d1 of the support wall 12d.
The through hole 12d2 of the support wall 12d and the through hole 14c1 of the rotation support portion 14c are aligned concentrically, and a bolt BN1 is inserted from the recess 12d1 side and tightened with a nut BN2.
Polyslider washers 4d, 4e, and 4f having high slidability are respectively interposed between the bolt BN1 and the support wall 12d, between the support wall 12d and the rotation support portion 14c, and between the rotation support portion 14c and the nut BN2.

In the slider portion 18, a bolt BN3 is inserted from the long hole 151 side into the through hole 14b2 and is tightened with a nut BN4.
Polyslider washers 4a, 4b, and 4c are respectively interposed between the bolt BN3 and the link guide 15, between the link guide 15 and the sliding support portion 14b, and between the sliding support portion 14b and the nut BN4.

A collar (not shown) of a predetermined length is interposed between the bolt BN1 and the nut BN2 of the link arm support portion 17 to prevent the bolt BN1 and the nut BN2 from locking when they are over-tightened.
As a result, the link arm 14 is always in an unlocked state and is adapted to rotate when a rotational torque equal to or greater than a predetermined value is applied thereto.
On the other hand, by tightening the bolt BN3 and the nut BN4, the slider portion 18 is first put into a usable state in which it can be rotated with a rotational torque of a predetermined value or more, and by further tightening, the rotational position of the base 14a about the rotation axis CL18 relative to the link guide 15 can be locked at a desired position.

FIG. 5 is a left side view showing a state in which the slider portion 18 has been moved (arrow DR18) to the rearmost position of the elongated hole 151, and is a view comparable to FIG.
As shown in Figure 5, the angle of the mounting plate 12 is angle θ2 which is smaller than angle θ1. Even when the windshield 3 is thus in a down position, the drive recorder 51 can be mounted with the optical axis CL11 generally horizontal.

FIG. 6 is a conceptual diagram showing the portions of the mounting plate 12 that support the main body 1 by hatched areas.
In the drive recorder 51, the mounting plate 12 supports the main body 1 at three locations: two hook portions 12c1, 12c2 on the left and right sides of the front end (lower Y end) and a link arm support portion 17 on the rear left (upper left Y). More specifically, the first support portion is the mounting plate support portion 16, the second support portion is the link arm support portion, and the third support portion is the slider portion 18.
That is, as shown in Figure 6, the mounting plate 12 supports the main body 1 by support corresponding portions AR161, AR162 that correspond to a pair of hook portions 12c1, 12c2 and are spaced apart in the left-right direction, and a support corresponding portion AR17 that corresponds to the link arm support portion 17.
The support corresponding portion AR17 is located at a position spaced above in the Y direction relative to the support corresponding portion AR161.

1, 2, and 5, the main body 1 has a center of gravity G located approximately in the center in the left-right direction and slightly forward of the center in the front-rear direction. When the drive recorder 51 is attached to the windshield 3, gravity Fa2 acts on the center of gravity G, and the adhesive member 2 supports the mounting plate 12 by adhesion against gravity Fa2.
Therefore, the gravity Fa2 acts on the adhesive member 2 in a dispersed manner at three locations, the support corresponding portions AR161, AR162, and AR17. Therefore, the force acting on each support corresponding portion is smaller than when the adhesive member 2 is supported at one location, and the adhesive member 2 is less likely to peel off from the inner surface 3a of the windshield 3 and the mounting plate 12.

Further, the support corresponding parts AR161, AR162 are located at both the left and right ends of the mounting plate 12, and the center of gravity G is located between the support corresponding parts AR161, AR162 in the left-right direction. That is, with respect to a vertical plane that includes the center of gravity G and divides the left and right sides, the support corresponding parts AR161, AR162 are located on the left and right sides, respectively.
As a result, the moments acting on the support corresponding parts AR161 and AR162 about their axes in the front-to-rear direction cancel each other out and become smaller.

1, the center of gravity G is located between the pair of support corresponding parts AR161, AR162 and the support corresponding part AR17 in the front-rear direction, as shown in FIG. 5.
As a result, the moments acting on the support corresponding parts AR161, AR162 and the support corresponding part AR17 about an axis in the left-right direction cancel each other out and become smaller.

In this manner, the weight of the main body 1 of the drive recorder 51 is applied to a plurality of dispersed regions of the adhesive member 2. Therefore, the adhesive member 2 is not easily peeled off from the inner surface 3a of the windshield 3 and the mounting plate 12.
In addition, the respective moments of the forces distributedly applied to the adhesive member 2 also act so as to cancel each other out in the front-rear and left-right directions.
Therefore, the adhesive member 2 is even less likely to peel off from the inner surface 3 a of the windshield 3 and the mounting plate 12 .

The embodiment described above is not limited to the above configuration, and may be modified without departing from the spirit of the present invention.

The drive recorder 51 of the embodiment has a pair of hook portions 12c of the mounting plate 12, 12c1 and 12c2, formed on the left and right sides of the front end (lower Y end) of the mounting plate 12. This is not limited to the above, and as a first modified example, the drive recorder 51A may have a mounting plate 12A with one hook portion 12Ac.

Fig. 7 is a front view of the drive recorder 51A. In Fig. 7, the drive recorder 51A has one hook portion 12Ac extending left and right across the position of the center of gravity G. The hook portion 12Ac engages with the support shaft portion 11c to form the attachment plate support portion 16A.
8, the support corresponding portion AR16A corresponding to the hook portion 12Ac becomes one area extending without any gaps in the left-right direction at the front end (lower end Y) of the mounting plate 12. Therefore, the force applied from the mounting plate support portion 16A to the adhesive member 2 is distributed over a surface and is further dispersed than in the case of the drive recorder 51, making the adhesive member 2 even more difficult to peel off from the inner surface 3a of the windshield 3 and the mounting plate 12A.

The drive recorder 51 of the embodiment is provided with a support group SG consisting of a mounting plate support portion 16, a link arm 14, and a link arm support portion 17, which supports the mounting plate 12 on the rear side (upper Y side), only on one of the left and right sides (left side).
Alternatively, the drive recorder 51 may be modified to a drive recorder 51A1 having a pair of support groups SG and SGA. The added right support group SGA is shown by a dashed line in Fig. 7. The drive recorder 51A1 uses a mounting plate 12A1.

FIG. 8 shows support corresponding parts AR17 and AR17A corresponding to a pair of support groups SG and SGA.
That is, FIG. 8 shows support corresponding parts AR16A, AR17, and AR17A of a drive recorder 51A1 of modified example 2 in which a support group SGA is further mounted on the drive recorder 51A of modified example 1.
As a result, the gravity Fa2 applied from the main body 1 is distributed to the adhesive member 2 in the left-right direction and the front-rear direction (Y-up-Y-down direction) so that each has a relatively large area. Therefore, the force per unit area applied to the adhesive force of the adhesive member 2 is smaller, and the effect on the adhesive force is smaller. Therefore, the adhesive member 2 is less likely to peel off from the inner surface 3a of the windshield 3 and the mounting plate 12A1.

The support corresponding parts AR16A, AR17, AR17A are located in symmetrical ranges in the left-right and front-back (Y up, Y down) directions with respect to position Gp (see Figures 5 and 8), also referred to as the mounting part center of gravity position, which intersects with the vertical line of the center of gravity G on the mounting plate 12A1.
As a result, the moments acting on the adhesive member 2 around the axis extending in the left-right direction and the moments acting on the axis extending in the Y-axis and Y-axis directions cancel each other out, and the moment acting in the direction of peeling off the adhesive member 2 becomes essentially negligible.
Therefore, the adhesive member 2 becomes even more difficult to peel off from the inner surface 3a of the windshield 3 and the mounting plate 12A1.

On the other hand, the mounting plate 12 is subjected to not only the weight of the main body 1 but also a force Fa1 from the cable 13. This force Fa1 is a force that pushes the mounting plate 12 downward in the Y direction as the cable 13 tries to return to its original straight state when it is bent due to being pulled out in the Y direction along the inner surface 3a of the windshield 3. The force Fa1 acts on the adhesive member 2 as a shear force.
Therefore, it is advisable to form a protrusion 12a on the upper surface 123 of the mounting plate 12. The protrusion 12a prevents the mounting plate 12 from moving downward in the Y direction due to the force Fa1.

Figure 9 is a cross-sectional view showing a mounting plate 12B having a protrusion 12a on the upper surface 123 as modification example 3, and corresponds to the cross section at the S9-S9 position in Figure 8.

As shown in FIG. 9, a plurality of protrusions 12a extending in the left-right direction (the front-to-back direction of the page) are arranged side by side in the Y-up-Y-down direction on the upper surface 123.
Each protrusion 12a has a bottom surface 12a1 that stands perpendicular to the top surface 123, and an inclined surface 12a2 that inclines in the direction Y upward from the tip of the bottom surface 12a1 toward the top surface 123, and has a triangular cross-sectional shape.

The protrusion 12a may be formed on the entire upper surface 123, or, as shown in Fig. 9, may be formed on a part of the upper surface 123. For example, the protrusion 12a is formed in a frame-shaped range along the periphery of the mounting plate 12B.
The frame-shaped area where the protrusions 12a are formed within the area where the adhesive member 2 is adhered is referred to as the shear force reinforcing area AR1. Also, on the upper surface 123, the intermediate area surrounded by the frame-shaped shear force reinforcing area AR1 is a flat surface where the protrusions 12a are not formed, and is referred to as the adhesive force reinforcing area AR2.

The height Hd of the protrusion 12a from the bottom surface 12a1 to the upper surface 123 is set to be less than a predetermined distance. The predetermined distance is a distance at which the adhesive member 2 can be elastically compressed in the thickness direction.
In a specific example, if the adhesive member 2 has a natural thickness of 3.0 mm and the elastically compressible distance in the thickness direction (amount of compression) is 1.8 mm, the height of the projection 12a is set to less than 1.8 mm.

When the adhesive member 2 is adhered to the upper surface 123 of the mounting plate 12B, the entire area of the adhesive member 2 is pressed against the upper surface 123 with a finger or the like to ensure a firm adhesion.
In particular, in the shear force reinforcement portion AR1, the adhesive member 2 is pressed with a finger or the like so as to adhere firmly to the shape of the protrusion 12a with as few gaps as possible; however, there is a risk that the valley portions between adjacent protrusions 12a may rise slightly due to the repulsion of the base material of the adhesive member 2.
In order to prevent this lifting, a flat adhesion strengthening portion AR2 without protrusions 12a is provided on the upper surface 123. In the adhesion strengthening portion AR2, the adhesive member 2 comes into surface contact with the upper surface 123 and adheres firmly.
This more reliably prevents the adhesive member 2 from lifting up at the shear force reinforcement portion AR1, and maintains the adhesive member 2 in a state where the protrusions 12a are biting into it.

With the adhesive member 2 adhered to the upper surface 123 of the mounting plate 12B, the adhesive member 2 is attached to the inner surface 3a of the windshield 3.
As a result, the drive recorder 51 is attached to the windshield 3.
10 and 11, a state in which the mounting plate 12B of the drive recorder 51 is attached to the windshield 3 will be described. In Fig. 10 and Fig. 11, the degree of curvature of the windshield 3 is exaggerated.
10 is a cross-sectional view of the mounting plate 12B taken horizontally at the adhesive strength reinforcing portion AR2, and FIG. 6 is a cross-sectional view of the mounting plate 12B taken vertically at the adhesive strength reinforcing portion AR2.

As shown in Figs. 5 and 6, the mounting plate 12B is formed in a flat plate shape, and the windshield 3 is curved and convex outward.
As shown in Figure 11, an external force Fa1 directed in the downward Y direction is applied to the mounting plate 12B from the cable 13, and the adhesive member 2 is sandwiched between the windshield 3 adhered to one side and the mounting plate 12 adhered to the other side and attempting to move in the downward Y direction due to the force Fa1, and a shear force is applied to the adhesive member 2.

Under this circumstance, the mounting plate 12B has a plurality of uneven portions into which the adhesive member 2 bites. The uneven portions are formed to include at least one of a protruding portion and a recessed portion with respect to the upper surface 123. Here, an example will be described in which the uneven portions are formed as protruding projections 12a.
The mounting plate 12B has a plurality of protrusions 12a that bite into the adhesive member 2. The mounting plate 12B is attached to the windshield 3 in a mounting position in which the bottom surfaces 12a1 of the protrusions 12a are perpendicular to the direction of the force Fa1 applied to the mounting plate 12B.
is a long and narrow surface extending in a direction perpendicular to the force Fa1.
As a result, even if the mounting plate 12 attempts to move in the Y-direction downward due to the force Fa1, the bottom surface 12a1 of the projection 12a bites into the adhesive member 2, preventing the movement.

In addition, since the bottom surface 12a1 is a surface perpendicular to the direction in which the force Fa1 is applied, even if the force Fa1 is large, the attachment plate 12B can resist the force Fa1 well and is prevented from moving downward in the Y direction relative to the adhesive member 2.
This makes it difficult for the mounting plate 12B to peel off from the adhesive member 2 when the force Fa1 is applied. That is, the drive recorder having the mounting plate 12B is unlikely to fall off from the windshield 3.

On the other hand, when the adhesive member 2 is adhered tightly to the inner surface 3a, which is the concave surface of the windshield 3, since the mounting plate 12B is flat, the adhesive member 2 is compressed more at the peripheral portion than at the central portion, resulting in a higher degree of compression.
Here, the mounting plate 12B has a shear force reinforcing portion AR1 having protrusions 12a at its peripheral portion. That is, at the shear force reinforcing portion AR1, the adhesive member 2 is compressed to a high degree, and the protrusions 12a bite more strongly into the adhesive member 2. Therefore, movement of the mounting plate 12B due to the force Fa1 can be more reliably prevented.
This makes the mounting plate 12B less likely to peel off from the adhesive member 2.

In the drive recorder 51 of the embodiment, the link arm 14 connecting the link arm support portion 17 and the slider portion 18 is a single arm, but the link arm 14 may be modified to be composed of multiple arms connected in series.
FIG. 12 is a schematic left side view showing a drive recorder 51C having two link arms 141, 142 connected by a joint portion 21 as the fourth modified example.

The joint 21 is, for example, a Hirth coupling that engages radially formed projections and recesses, and is a connecting part that can determine the crossing angle of the two link arms. That is, the link arms 141 and 142 can be locked at a desired angle with a predetermined pitch.
One end of the link arm 141 is connected to the joint portion 21, and one end of the link arm 141 is rotatably supported by the link arm support portion 17. One end of the link arm 142 is connected to the joint portion 21, and the other end of the link arm 142 is rotatably connected to the slider portion 18. On the mounting plate 12, the link arm support portion 17 is provided at position P1.
This makes it possible to widen the adjustment range of the erect angle of the mounting plate 12 even when the length of the long hole 151 is insufficient due to restrictions on the shape of the main body 1, for example.

Figure 13 shows a drive recorder 51D as variant 5, in which the link arm support portion 17 is not provided on the mounting plate 12 of the drive recorder 51C, but is provided on a support member 22 that has a mounting plate 12D and is fixed at two locations, positions P2 and P3, spaced apart in the up-down direction Y from the mounting plate 12D.
As a result, the gravity Fa2 acting on the center of gravity G of the main body 1 is further divided and applied to the mounting plate 12D, so that the adhesive member 2 is less likely to peel off from the inner surface 3a of the windshield 3 and the mounting plate 12D.

FIG. 14 shows a drive recorder 51E as a sixth modified example. The drive recorder 51E does not have a link arm support portion 17 connected to the mounting plate 12D as a plurality of point-like portions as in the drive recorder 51D. In detail, the drive recorder 51E has a mounting plate 12E, and the link arm support portion 17 is connected to the mounting plate 12E in a linear range P4 by a rail 23 that engages with a rail guide (not shown) provided to extend in the Y-axis up-down direction. Instead of the rail guide and the rail 23, the link arm support portion 17 may be configured to extend in the Y-axis up-down direction relative to the mounting plate 12E. In other words, the link arm support portion 17 may be a rod-shaped member that connects the mounting plate 12E and the link arm 141.
As a result, the gravity Fa2 acting on the center of gravity G of the main body 1 with respect to the mounting plate 12E is applied to the entire range P4 extending in the Y-up and Y-down directions at the left and right edges, in addition to the mounting plate support portion 16. In other words, the force per unit area acting on the adhesive member 2 by the gravity Fa2 is further reduced.

Fig. 15 is a plan view illustrating the support corresponding portions AR16A, AR231, and AR232 of the mounting plate 12E. As shown in Fig. 15, gravity Fa2 acts on the lower Y, left, and right edges of the mounting plate 12E in a planar manner rather than a point manner.
This reduces the force per unit area applied to the adhesive member 2, making the adhesive member 2 less likely to peel off from the inner surface 3a of the windshield 3 and the mounting plate 12.

The mounting members for the hook portion 12c and the support shaft portion 11c in the mounting plate support portion 16 may be reversed to those in the embodiment.
That is, the mounting plate support portion 16 may have the hook portion 12c formed on the main body portion 1 side and the support shaft portion 11c formed on the mounting plate 12 side.

The above-described embodiment and modifications 1 to 6 may be combined as appropriate.
For example, the shear force reinforcing portion AR1 may be provided so as to include the mounting plate support portion 16. For example, in the configuration shown in Fig. 14 in which the rod-shaped link arm support portion 17 connects the mounting plate 12E and the link arm 141, the link arm support portion 17 may be disposed on the peripheral portion of the mounting plate 12E. In this case, the gravity Fa2 acting on the center of gravity G of the main body 1 is distributed and applied to the peripheral portion where the degree of compression of the adhesive member 2 with respect to the mounting plate 12E is high, so that the adhesive member 2 is less likely to peel off from the inner surface 3a of the windshield 3 and the mounting plate 12.

The link arm 14 has been described as being rotatable relative to the mounting plate 12, but if the electronic component does not require adjustment of the mounting angle, it may be fixedly connected without rotating. In this case, the hook portion 12c of the mounting plate 12 may be a support portion that is shaped to provide fixed support rather than a hook shape that allows relative rotation. The same applies to the link arm 14.

Although a drive recorder has been described as an example of an electronic device that can be used as a mounting member, the electronic device is not limited to a drive recorder. The mounting member is not limited to a windshield. For example, the mounting member may be the dashboard of a vehicle or the windshield of a two-wheeled vehicle, and the mounting member may be a communication terminal device, a vehicle camera, an infrared camera, a distance sensor, or the like. Furthermore, the above-mentioned mounting method for electronic devices is not limited to mobile objects, and may be used as a method for mounting electronic devices such as cameras to window glass in a house.
