Description

TECHNICAL FIELD

[0001] The present disclosure relates to a mounting device. BACKGROUND

[0002] In the related art, a mounting device that mounts a sensor such as a camera on a vehicle has been put into practical use. The mounting device is provided in a manner that fixes the camera to a cabin side with respect to a windshield of the vehicle, and is capable of taking an image of an outside of the vehicle through the fixed camera across the windshield.

[0003] Here, sometimes the windshield fogs up, for example, due to a temperature difference between the cabin and the outside of the vehicle, and it can be impossible to take a clear image through the camera due to the fogging of the windshield.

[0004] Therefore, as a technique to remove the fogging of the windshield, for example, in Patent Literature 1, a vehicle-mounted camera device that suppresses fogging of a portion of the windshield located in front of the camera device is proposed. The vehicle-mounted camera device is configured with a heat wire that heats the windshield, and thus is capable of removing the fogging of the windshield.

[0022] Hereinafter, the embodiments of the present disclosure will be described based on the drawings.

[0023] (Embodiment 1)

[0024] Figure 1A structure of a sensor device provided with the mounting device of Embodiment 1 of the present disclosure is shown in FIG. 1. The sensor device has a mounting device 1, an imaging section 2, a temperature measuring section 3, a control section 4, and a power supply 5.

[0025] The mounting device 1 is for mounting the imaging section 2 to the surface Fb side in the vehicle cabin in a manner capable of detecting transmitted light transmitted from the surface Fa side outside the vehicle on the windshield F, and has a support section 6, a heating section 7, and a conducting section 8.

[0026] The support section 6 is disposed between the windshield F and the imaging section 2, and has a fixed section 9a and a fixed section 9b, and a recessed section 10. The support section 6 can be composed of a synthetic resin having heat resistance, for example. In addition, the support section 6 can be formed in a color that does not affect imaging by the imaging section 2, and can be formed in black, for example.

[0027] The fixed section 9a is disposed at an upper edge section of the support section 6, and is formed in a flat plate shape in a manner to abut against the surface Fb of the windshield F. The fixed section 9a is fixed to the windshield F by an adhesive, for example.

[0028] The fixed section 9b is disposed at a lower edge section of the support section 6, and is formed in a flat plate shape in a manner to abut against the surface Fb of the windshield F. The fixed section 9b is fixed to the windshield F by an adhesive, for example.

[0029] The recessed section 10 is disposed between the fixed section 9a and the fixed section 9b, and is formed in a manner to be recessed toward the vehicle cabin side, away from the windshield F. In addition, a window section 11 is formed on the recessed section 10 in a manner to face an opening section 12 of the recessed section 10, and the window section 11 exposes the imaging section 2 toward the windshield F side through an upper section of the recessed section 10. In addition, the recessed section 10 has an opposing surface 10a formed in a manner to oppose the windshield F and to gradually move away from the windshield F as it moves from the opening section 12 toward the window section 11, and a back surface 10b disposed on the opposite side of the opposing surface 10a. In addition, the recessed section 10 has a side surface 10c rising from the opposing surface 10a toward the windshield F, and the window section 11 is formed at an upper section of the side surface 10c.

[0030] Thus, the recessed section 10 forms a detection space S corresponding to the imaging range of the imaging section 2 on the front surface of the imaging section 2.

[0031] The heating section 7 is disposed along the back surface 10b of the recessed section 10, and heats the recessed section 10 from the back surface 10b side.

[0032] The conduction section 8 is for conducting heat conducted from the heating section 7 along the opposing surface 10a via the recess 10, is formed in a flat plate shape with a uniform thickness, and is arranged so as to extend along the opposing surface 10a of the recess 10. Further, the conduction section 8 radiates heat conducted along the opposing surface 10a toward the windshield F to the detection space S. The conduction section 8 is composed of a material with a high thermal conductivity, for example, aluminum, copper, or the like. In addition, the conduction section 8 can be formed in a color that does not affect imaging by the imaging section 2, for example, can be painted black.

[0033] The imaging section 2 is for detecting transmitted light transmitted through the windshield F, and thereby imaging the outside of the vehicle, is arranged with the support section 6 interposed between the windshield F, and a lens portion thereof is exposed to the side of the windshield F from the window portion 11 formed in the recess 10. The imaging section 2 can be composed of a video camera or the like, for example.

[0034] In addition, the imaging section 2 is held to the support section 6 by a holding section 2a. The holding section 2a is arranged so as to extend from the back surface 10b of the support section 6 to the window portion 11, has one end portion fixed to the back surface 10b of the support section 6, and has the other end portion fixed to the imaging section 2.

[0035] The temperature measurement section 3 is for measuring the temperature of the outside of the vehicle, and can be composed of a thermometer or the like, for example.

[0036] The power supply 5 is for supplying power to the heating section 7 so as to heat the heating section 7.

[0037] The control section 4 switches on and off the power supply 5 based on the temperature measured by the temperature measurement section 3, and thereby controls heating of the heating section 7 toward the windshield F.

[0038] Next, the structure of the support section 6 will be described in detail.

[0039] Figure 2 FIG. 3 illustrates the structure of the opposing surface 10a side of the support section 6.

[0040] The recess 10 has three side surfaces 10c, 10d, and 10e that rise from the opposing surface 10a toward the windshield F. The side surface 10c is arranged so as to connect between the deep side portion of the opposing surface 10a and the fixing section 9a. The side surface 10d is arranged on the right side when viewed in a detection direction Dl toward which the imaging section 2 takes a picture, and is formed so as to extend to the right side from the side surface 10c, the right side being the right side when viewed in the detection direction Dl. The side surface 10e is arranged on the left side when viewed in the detection direction Dl, and is formed so as to extend to the left side from the side surface 10c, the left side being the left side when viewed in the detection direction Dl. That is, the side surface 10d and the side surface 10e are formed so as to gradually separate in the left-right direction D2 as they go from the window portion 11 side toward the detection direction Dl.

[0041] A fixing portion 9c is disposed on the upper edge of side surface 10d, contacting surface Fb of windshield F. Furthermore, a fixing portion 9d is disposed on the upper edge of side surface 10e, contacting surface Fb of windshield F. Specifically, fixing portions 9a to 9d are disposed so as to surround opening 12 of recess 10. Fixing portions 9c and 9d are secured to windshield F using, for example, an adhesive.

[0042] Opposing surface 10a corresponds to the shape of side surfaces 10d and 10e, and is formed into a trapezoidal shape, gradually expanding in the left-right direction D2 as it moves from side surface 10c toward fixed portion 9b. The expansion of opposing surface 10a, side surfaces 10d, and side surfaces 10e in the left-right direction D2 is set to correspond to the expansion of the detection range of imaging unit 2, thereby forming a predetermined detection space S.

[0043] Furthermore, the conductive portion 8 is disposed on the opposing surface 10a and is formed so as to gradually expand in the left-right direction D2 along the opposing surface 10a as it moves from the window portion 11 side toward the detection direction D1. Specifically, the conductive portion 8 has a trapezoidal shape corresponding to the opposing surface 10a and is formed so as to cover substantially the entire surface of the opposing surface 10a.

[0044] Figure 3 3 shows the structure of the back surface 10b side of the support portion 6.

[0045] The heating unit 7 is arranged on the back surface 10b of the support unit 6. Here, the holding unit 2a holding the imaging unit 2 is fixed to the fixing region R on the back surface 10b of the support unit 6. Therefore, the heating unit 7 is arranged in a shape avoiding the fixing region R.

[0046] A heating wire 7a is disposed over the entire surface of the heating portion 7, and a pair of terminals of the heating wire 7a are connected to the power source 5. The heating wire 7a has a predetermined resistance and is heated by power supplied by the power source 5.

[0047] Next, the operation of the first embodiment will be described.

[0048] First, if Figure 1 As shown, the imaging unit 2 fixed to the support portion 6 by the holding portion 2a is arranged so as to be exposed from the window portion 11 toward the windshield F side, and images the outside of the vehicle through the windshield F.

[0049] At this time, if Figure 2 As shown, the support portion 6 is fixed to the windshield F via the fixing portions 9a to 9d arranged so as to surround the recessed portion 10. Therefore, the imaging unit 2 can be firmly supported.

[0050] Furthermore, the facing surface 10a, side surface 10d, and side surface 10e of the recessed portion 10 are arranged so as to expand in the left-right direction D2 as they extend from the window portion 11 side toward the detection direction D1 of the imaging unit 2, thereby forming a detection space S corresponding to the imaging range of the imaging unit 2. Due to the presence of this detection space S, the imaging unit 2 can reliably capture the situation outside the vehicle without its imaging range being obstructed.

[0051] Here, if the temperature outside the vehicle drops, the windshield F may fog up, obstructing the image capture by the imaging unit 2. Therefore, the temperature measuring unit 3 measures the temperature outside the vehicle and outputs the temperature to the control unit 4. The control unit 4 determines whether the temperature measured by the temperature measuring unit 3 is below a predetermined value, and turns on the power supply 5 if the temperature is below the predetermined value.

[0052] Therefore, if Figure 3 As shown, power is supplied from the power source 5 to the heating wire 7a of the heating unit 7, causing the heating unit 7 to heat the back surface 10b of the recessed portion 10. Heat from the heating unit 7 is conducted from the back surface 10b of the recessed portion 10 toward the opposing surface 10a, and is input to the conducting unit 8. The conducting unit 8 then conducts the heat from the heating unit 7 along the opposing surface 10a and dissipates it toward the windshield F and into the detection space S. The heat dissipated into the detection space S thus raises the temperature of the windshield F, thereby defogging the windshield F.

[0053] In this case, the conductive portion 8 is positioned so as to extend along the opposing surface 10a. Meanwhile, the heating portion 7 is positioned so as to avoid the fixed region R where the holding portion 2a is secured. Since the back surface 10b of the support portion 6 houses not only the holding portion 2a but also various other devices, the heating portion 7 is not only limited by the fixed region R but also faces various other restrictions, such as being placed within a narrow area. While placing the heating portion 7 on the back surface 10b offers the advantage of easier wiring installation, it also presents the disadvantage of limiting its installation range.

[0054] In this way, when the heating part 7 is arranged to avoid a part of the back side 10b, if the conduction part 8 is removed and the heat of the heating part 7 is directly dissipated to the detection space S, there is a possibility that fogging of the windshield F will remain locally, thereby hindering the camera part 2 from shooting and causing a hidden danger of reduced shooting accuracy.

[0055] Therefore, if Figure 2 As shown, by arranging the conduction portion 8 so as to extend along the facing surface 10a, the heat conducted from the heating portion 7 is widely and evenly conducted along the facing surface 10a. This can remove fogging from the windshield F over a wide area, thereby suppressing a decrease in the imaging accuracy, or detection accuracy, of the imaging unit 2.

[0056] Further, the conductive portion 8 is arranged so as to cover the entire surface of the opposing surface 10a. Thus, it is possible to remove fogging in the entire portion of the windshield F corresponding to the detection space S, that is, the entire detection range of the imaging portion 2, and further, it is possible to reliably suppress a decrease in the imaging accuracy of the imaging portion 2.

[0057] On the other hand, the control portion 4 turns off the power supply 5 when the temperature measured by the temperature measuring portion 3 is higher than the prescribed value.

[0058] Thus, the control portion 4 controls heating of the heating portion 7 based on the temperature measured by the temperature measuring portion 3, and thus it is possible to suppress fogging of the windshield F and maintain the imaging accuracy of the imaging portion 2.

[0059] In the present embodiment, the conductive portion 8 is arranged so as to extend along the opposing surface 10a, and thus it is possible to uniformly conduct heat from the heating portion 7 along the opposing surface 10a. Thus, it is possible to remove fogging of the windshield F in a large range, and further, it is possible to suppress a decrease in the imaging accuracy of the imaging portion 2.

[0060] (Embodiment 2)

[0061] Hereinafter, Embodiment 2 of the present disclosure will be described. Here, the description will be made focusing on the difference from Embodiment 1 described above, and the same reference numerals will be used for the same portions as those of Embodiment 1, and the detailed description thereof will be omitted.

[0062] In Embodiment 1 described above, the conductive portion 8 is arranged on the opposing surface 10a, but it is not limited thereto as long as it is arranged along the opposing surface 10a.

[0063] For example, as shown in FIG. 21, a conductive portion 21 can be arranged instead of the conductive portion 8 of Embodiment 1. Figure 4

[0064] The conductive portion 21 is arranged so as to be buried in the recess 10 in a manner that it extends along the opposing surface 10a of the recess 10 and its surface is exposed to the detection space S. Here, the conductive portion 21 is arranged in a manner that its surface is located on the same surface as the opposing surface 10a of the recess 10.

[0065] Thus, the conductive portion 21 widely and uniformly conducts heat from the heating portion 7 along the opposing surface 10a, and it is possible to remove fogging of the windshield F in a large range, and further, it is possible to suppress a decrease in the imaging accuracy of the imaging portion 2.

[0066] Further, since the conductive portion 21 is buried in the recess 10 in a manner that its surface is exposed, it is possible to suppress the amount of protrusion from the opposing surface 10a while maintaining the strength of the support portion 6. At this time, since the conductive portion 21 is arranged in a manner that its surface is located on the same surface as the opposing surface 10a of the recess 10, it is possible to eliminate the protrusion from the opposing surface 10a.​

[0067] According to the present embodiment, the conductive portion 21 is embedded in the recess 10 in a manner that its surface is exposed, and thus can suppress the protruding amount from the opposing surface 10a while maintaining the strength of the support portion 6.

[0068] Note that, in the present embodiment, the conductive portion 21 is configured in a manner that its surface is exposed, but this is not limiting as long as it is configured in a manner that it extends along the opposing surface 10a. For example, as shown in FIG. 9, the conductive portion 21 can be configured in a manner that its surface is also completely embedded in the recess 10 along the opposing surface 10a. Figure 5

[0069] (Embodiment 3)

[0070] Next, Embodiment 3 of the present disclosure will be described. Here, the description will be made focusing on the difference from Embodiments 1 and 2 described above, and the same reference numerals will be used for the same parts as those of Embodiments 1 and 2, and the detailed description thereof will be omitted.

[0071] In Embodiments 1 and 2 described above, the conductive portion is configured in a manner that it extends along the opposing surface 10a only, but this is not limiting as long as it is configured in a manner that it extends along the opposing surface 10a.

[0072] For example, as shown in FIG. 9, the conductive portion 31 can be configured instead of the conductive portion 8 of Embodiment 1. Figure 6

[0073] The conductive portion 31 has a bottom portion 31a and three side wall portions 31b to 31d. The bottom portion 31a has a plate shape and is configured in a manner that it extends along the opposing surface 10a of the recess 10 to the entire opposing surface 10a. The side wall portion 31b has a plate shape and is configured in a manner that it extends along the side surface 10c of the recess 10 to the entire side surface 10c. The side wall portion 31c has a plate shape and is configured in a manner that it extends along the side surface 10d of the recess 10 to the entire side surface 10d. The side wall portion 31d has a plate shape and is configured in a manner that it extends along the side surface 10e of the recess 10 to the entire side surface 10e. The bottom portion 31a and the side wall portions 31b to 31d are connected to each other at their edge portions in an integrated manner.

[0074] ​​Thus, the bottom portion 31a of the conduction portion 31 conducts the heat conducted from the heating portion 7 widely and uniformly along the opposing surface 10a of the recessed portion 10. Also, the side wall portions 31b to 31d conduct the heat conducted in the bottom portion 31a uniformly along the side surfaces 10c to 10e of the recessed portion 10. In this way, the conduction portion 31 conducts the heat conducted from the heating portion 7 along the opposing surface 10a and the side surfaces 10c to 10e, and thus the entire detection space S can be warmed up, and further, the fogging of the windshield F can be easily removed. Thus, the decrease in the imaging accuracy of the imaging portion 2 can be reliably suppressed.

[0075] According to the present embodiment, the conduction portion 31 is arranged in a manner that the bottom portion 31a extends along the opposing surface 10a of the recessed portion 10, and in a manner that the side wall portions 31b to 31d extend along the side surfaces 10c to 10e of the recessed portion 10. Thus, the entire detection space S can be warmed up, and further, the decrease in the imaging accuracy of the imaging portion 2 can be reliably suppressed.

[0076] (Embodiment 4)

[0077] Hereinafter, Embodiment 4 of the present disclosure will be described. Here, the description will be made focusing on the difference from the above-described Embodiments 1 to 3, and the same reference numerals will be used for the same parts as those of the above-described Embodiments 1 to 3, and the detailed description thereof will be omitted.

[0078] In the above-described Embodiments 1 to 3, the conduction portion is formed to have a uniform thickness, but as long as it is arranged in a manner that it extends along the opposing surface 10a, it is not limited thereto.

[0079] For example, as shown in FIG. 9, a conduction portion 41 can be arranged instead of the conduction portion 8 of Embodiment 1. Figure 7

[0080] In the conduction portion 41, the spacing region Fl farthest from the windshield F in the heat dissipation direction D3 toward the upper side from the opposing surface 10a is formed thicker than a region closer to the windshield F than the spacing region Fl in the heat dissipation direction D3, for example, an intermediate region F2. Also, in the conduction portion 41, an edge portion region F3 of the edge portion on the side of the fixed portion 9b formed longest among the four edge portions is formed thicker than a region farther from the edge portion, for example, the intermediate region F2.

[0081] Thus, the conduction portion 41 conducts the heat conducted from the heating portion 7 widely along the opposing surface 10a of the recessed portion 10. At this time, the spacing region Fl and the edge portion region F3 of the conduction portion 41 are formed thicker than the intermediate region F2.

[0082] In general, the farther the distance of the conduction portion 41 from the windshield F in the heat dissipation direction D3, the more the heat emitted from the conduction portion 41 is cooled during the transfer in the detection space S, and thus it is difficult to remove the fogging of the windshield F.​

[0083] In addition, the portion of the windshield F corresponding to the edge portion of the conductive portion 41 is cooled from the outside by the outside air, and thus it is difficult to remove fogging of the windshield F. In particular, the portion of the windshield F corresponding to the edge portion region F3 is formed to be long in the left-right direction D2, and thus it is difficult to remove fogging of the windshield F.

[0084] Therefore, the spacing region F1 of the conductive portion 41 is formed to be thick. Thus, in the conductive portion 41, the amount of heat dissipation from the spacing region F1 is increased, and thus it is possible to reliably remove fogging of the portion of the windshield F that is far from the conductive portion 41.

[0085] Further, the edge portion region F3 of the conductive portion 41 is formed to be thick. Thus, in the conductive portion 41, the amount of heat dissipation from the edge portion region F3 is increased, and thus it is possible to reliably remove fogging of the portion of the windshield F that is easily cooled by the outside air. At this time, the edge portion region F3 is provided near the edge portion that is formed to be the longest in the conductive portion 41, and thus it is possible to reliably remove fogging of the portion of the windshield F that is most easily cooled by the outside air.

[0086] Note that, in the present embodiment, the edge portion region F3 is formed to be thick in the conductive portion 41, but it is not limited thereto as long as the edge portion is formed to be thick.

[0087] According to the present embodiment, the spacing region F1 that is farthest from the windshield F in the heat dissipation direction D3 is formed to be thick in the conductive portion 41, and thus it is possible to reliably remove fogging of the windshield F. Further, the edge portion is formed to be thick in the conductive portion 41, and thus it is possible to reliably remove fogging of the windshield F.

[0088] Note that, in the above-described embodiments 1 to 4, the conductive portion is formed to be plate-shaped, but it is not limited thereto as long as it is disposed so as to extend along the opposing surface 10a of the recess 10. For example, the conductive portion can be formed to be mesh-shaped.

[0089] Further, in the above-described embodiments 1 to 4, the mounting device 1 mounts the imaging portion 2 that detects transmitted light, but it is not limited thereto as long as it can mount a sensor that detects a transmitted wave transmitted through the windshield F. For example, the mounting device 1 can be configured to mount a sensor such as a laser radar, a millimeter wave radar, and an ultrasonic sensor.

[0090] Note that the transmitted wave has a prescribed frequency, and examples thereof include visible light, ultraviolet light, infrared light, millimeter waves, and ultrasonic waves.

[0091] In addition, in the above-described embodiments 1 to 4, the mounting device 1 is mounted with the imaging section 2 with respect to the windshield F, but the imaging section 2 can be mounted to a transmission plate that transmits transmitted light, and is not limited to the windshield F.

[0092] In addition, in the above-described embodiments 1 to 4, the support section 6 is directly fixed to the windshield F, but can be fixed between the windshield F and the imaging section 2, and is not limited thereto.

[0093] Further, the above-described embodiments merely represent one example of embodying the present application, and the technical scope of the present application should not be limited to these embodiments. That is, the present application can be embodied in various forms without departing from the gist or main features thereof. For example, the shape and number of each section described in the above-described embodiments are merely examples, and can be appropriately changed.

[0094] This application is based on Japanese Patent Application (JP 2020-025232) filed on February 18, 2020, the content of which is incorporated herein by reference in its entirety.
