Patent Documents 1 and 2 disclose a configuration in which heat generated from a sensor is released to a windshield.

JP 2016-14564 A JP-A-2006-208125

   Patent Literature 1 discloses a structure in which a heat transfer member made of aluminum, copper, or the like having a high thermal conductivity is closely attached to a windshield to release heat of the sensor to the windshield. However, since metal materials such as aluminum and copper have high rigidity and rigidity, the vibration of the vehicle body may cause the heat transfer member to hit the windshield and damage the windshield. In order to avoid such a situation, it is necessary to interpose a flexible and flexible member between the heat transfer member and the windshield. However, with such a structure, the heat transfer member cannot be brought close to the windshield. For this reason, there has been a problem that heat cannot be sufficiently released from the heat transfer member to the windshield.

   Patent Document 2 discloses a structure in which a heat conductive member made of a silicone material is arranged between a bracket and a windshield. However, since the bracket of Patent Literature 2 is made of a resin material, the heat of the sensor is not sufficiently transmitted to the bracket, and as a result, there is a problem that the heat of the sensor is hardly released to the windshield.

   In view of the above problems, an object of the present invention is to provide a bracket that stably fixes a sensor to a glass surface and that can efficiently transmit heat generated by a sensor body to the glass surface.

   A bracket according to one embodiment of the present invention is a bracket for fixing a sensor main body for sensing the outside of a vehicle to a glass surface on the vehicle interior space side of a vehicle. The bracket includes a heat transfer member that extends in the horizontal and vertical directions and has a heat transfer surface facing the glass surface, and is fixed to the heat transfer member, and the edge in the horizontal direction of the heat transfer member and the heat transfer member And a support member arranged adjacent to one or both of the edges in the vertical direction. The heat transfer member is made of a metal material. The support member has a contact portion that contacts the glass surface when the bracket is attached to the glass surface. In a state where the bracket is attached to the glass surface, the heat transfer surface and the contact portion are arranged along the glass surface. The contact portion deforms according to the shape of the glass surface when the bracket is attached to the glass surface.

   According to one aspect of the present invention, it is possible to provide a bracket capable of stably fixing a sensor to a glass surface and efficiently transmitting heat generated by the sensor body to the glass surface.

FIG. 1 is a schematic cross-sectional view of a vehicle equipped with the sensor device. FIG. 2 is an exploded perspective view of the sensor device. FIG. 3 is a side view of the sensor device.

   Hereinafter, the bracket 3 and the sensor device 2 according to the embodiment of the present invention will be described with reference to the drawings. In the following drawings, in order to make each configuration easy to understand, in a case where the scale and the number of each structure are different from those of an actual structure, portions which are not features may be omitted.

   In the following description, when the sensor device 2 is mounted on the vehicle 1, the vehicle width direction is the width direction or the left-right direction of the sensor device 2, the vehicle front-rear direction is the sensor device 2 front-rear direction, and the vehicle 1 Is defined as the vertical direction of the sensor device 2. Note that the posture and arrangement of each member of the sensor device 2 is an example, and can be changed without departing from the spirit of the present invention.

<Vehicle>
FIG. 1 is a schematic cross-sectional view of a vehicle 1 on which a sensor device 2 is mounted. The vehicle 1 has a windshield 10 which is a front facing window glass and a rear glass 15 which is a rear facing window glass. Further, the vehicle 1 is provided with a vehicle interior space 1a located between the front glass 10 and the rear glass 15 in the front-rear direction. The vehicle interior space 1a is a living space of a passenger riding the vehicle 1. The vehicle interior space 1a is also a space where luggage can be loaded. In the present embodiment, the vehicle interior space 1 a is a space isolated from the outside of the vehicle 1. For example, when the ceiling of the vehicle 1 is open, the vehicle interior space 1a may be a space connected to the outside of the vehicle 1.

The vehicle 1 has a drive mechanism (not shown). The drive mechanism includes an engine, a steering mechanism, a power transmission mechanism, wheels, and the like. Further, an electric motor may be used instead of the engine.
In addition, the vehicle 1 of this embodiment is an example. The vehicle is not limited to a passenger car, but may be a truck, a train, or the like.

<Sensor device>
The sensor device 2 is attached to a glass surface 10a of the windshield 10 on the side of the vehicle interior space 1a, and is used for sensing outside the vehicle (more specifically, in front of the vehicle 1).
As shown by a two-dot chain line in FIG. 1, the sensor device 2 may be mounted on a glass surface 15 a of the rear glass 15 on the side of the vehicle interior space 1 a. When the sensor device 2 is attached to the rear glass 15, the sensor device 2 is used for sensing the rear of the vehicle 1.

   FIG. 2 is a perspective view of the sensor device 2. FIG. 3 is a side view of the sensor device 2. In FIG. 2, the sensor device 2 is in a state of being disassembled into a sensor main body 4 and a bracket 3.

   As shown in FIG. 2, the sensor device 2 has a sensor body 4 and a bracket 3. Further, the sensor device 2 may have an outer cover fixed to the bracket 3 and protecting the sensor main body 4.

<Sensor body>
The sensor body 4 of the present embodiment is a fusion type having a radar device 41 and an imaging device 45. The sensor body 4 is fixed to the bracket 3.

   The sensor body 4 includes a case 40, a radar device 41, an imaging device 45, and a control unit 49. The control unit 49 controls the radar device 41 and the imaging device 45. The control unit 49 has a substrate 49a and an integrated circuit 49b mounted on the upper surface of the substrate 49a.

   The case 40 houses the radar device 41, the imaging device 45, and the control unit 49. The case 40 is made of a metal material made of aluminum or an aluminum alloy. The case 40 may be composed of a plurality of members.

The radar device 41, the imaging device 45, and the control unit 49 are fixed to the case 40. In addition, at least a part of the electronic devices constituting the radar device 41, the imaging device 45, and the control unit 49 directly contact the case 40. Therefore, part of the heat generated by the radar device 41, the imaging device 45, and the control unit 49 is transmitted to the case 40.
The electronic devices constituting the radar device 41, the imaging device 45, and the control unit 49 may be indirectly in contact with the case 40 via a member having high thermal conductivity. A member such as a heat conductive sheet or heat conductive grease may be interposed at a portion where the electronic element and the case 40 are in contact with each other. By doing so, the adhesion between the electronic element and the case 40 is enhanced, and heat conduction is promoted. Even in this case, the heat generated from the electronic element is positively transmitted to the case 40.

The case 40 has an upper end surface 40a facing upward. The upper end surface is located immediately above the region where the control unit 49 is accommodated in the case 40. The upper end surface 40a faces the glass surface 10a via the bracket 3. As shown in FIG. 3, the upper end face 40 a is vertically opposed to the bracket 3 via the gap G.
In addition, as a modified example of the present embodiment, a configuration in which the upper end surface 140a contacts the bracket 3 may be adopted. More specifically, the upper end surface 140a of the modification contacts the heat transfer member 31 of the bracket 3 described later.

   As shown in FIG. 2, the case 40 includes a pair of shaft portions 46 extending in the left-right direction, and a pair of claw portions 47 projecting in the left-right direction. The shaft portion 46 and the claw portion 47 are provided on the left side surface and the right side surface of the case 40, respectively. The claw portion 47 is disposed rearward with respect to the shaft portion 46. As will be described later, the case 40 is supported by the bracket 3 at the shaft 46 and the claw 47.

   The radar device 41 is a device that is used when avoiding collision with an obstacle or the like or assisting a driver in driving. The radar device 41 irradiates the millimeter wave to the front or rear of the vehicle 1. The radar device 41 receives a radar wave reflected by the device under test and detects the distance to the device under test and the direction of the device under test.

   The imaging device 45 is a camera that captures a scene in front of or behind the vehicle. The imaging device 45 has a lens 45a and an imaging element (not shown) located behind the lens 45a. The lens 45a has the optical axis in the front-rear direction. The imaging element captures a subject image formed through a lens as image data. The imaging device 45 may be connected to a storage device via the control unit 49. In this case, the image captured by the imaging device 45 is stored in the storage device.

<Bracket>
The bracket 3 is used to fix the sensor body 4 to the glass surface 10a on the side of the vehicle interior space 1a of the vehicle 1. The bracket 3 is fixed to the glass surface 10a of the windshield 10. Further, the bracket 3 supports the case 40 of the sensor main body 4. The bracket 3 determines the mounting posture of the sensor body 4 with respect to the glass surface 10a.

   The bracket 3 is fixed to a predetermined position of the windshield 10, for example, a glass surface 10a near a room mirror. The bracket 3 supports the sensor main body 4 so that the sensor main body 4 is oriented along the glass surface 10a. In the present embodiment, the case where the bracket 3 is used to fix the sensor body 4 to the glass surface 10a on the side of the vehicle interior space 1a of the vehicle 1 is shown. It may be used to fix the sensor body 4 to the glass surface 15a.

   The bracket 3 has a heat transfer member 31 and a support member 35. The heat transfer member 31 and the support member 35 are fixed to each other. The bracket 3 transmits heat generated by the sensor main body 4 to the glass surface 10a in the heat transfer member 31. The bracket 3 is fixed to the glass surface 10a at the support member 35. Further, the bracket 3 supports the sensor main body 4 on the support member 35.

(Heat transfer member)
Heat transfer member 31 is made of a metal material. Generally, a metal material has a higher thermal conductivity than a resin material. When the heat transfer member 31 is made of a metal material, the heat transfer member 31 can efficiently absorb heat from the sensor main body 4 and can efficiently release the heat to the glass surface 10a. The heat transfer member 31 is more preferably made of aluminum or an aluminum alloy which has a high thermal conductivity and is relatively inexpensive among metal materials. The heat transfer member 31 is formed by, for example, press working.

   The heat transfer member 31 has a heat transfer portion 32, an eaves portion 33, and a step portion.

   The heat transfer section 32 is a flat plate extending along the glass surface 10a. The heat transfer section 32 is substantially rectangular in plan view. The heat transfer section 32 has a heat transfer surface 32a facing the glass surface 10a. That is, the heat transfer member 31 has the heat transfer surface 32a. The heat transfer member 31 transfers heat to the glass surface 10a on the heat transfer surface 32a.

The heat transfer surface 32a extends in the horizontal direction D1 and the vertical direction D2.
In this specification, the horizontal direction D1 and the vertical direction D2 are directions in a plane of a predetermined plane. In this specification, the lateral direction D1 is a direction coinciding with the width direction of the vehicle. In this specification, the vertical direction D2 is a direction orthogonal to the horizontal direction D1 in the plane of the heat transfer surface 32a.

   The heat transfer surface 32a of the present embodiment is a plane whose dimension in the vertical direction D2 is larger than the dimension in the horizontal direction D1. Generally, the glass surface 10a is a concave curved surface that is concave toward the outside of the vehicle. In general, the curvature of the glass surface 10a in the vertical direction D2 is smaller than the curvature in the horizontal direction D1. That is, the glass surface 10a is a nearly flat curved surface in the vertical direction D2. Therefore, by making the heat transfer surface 32a longer in the vertical direction D2, the entire heat transfer surface 32a can be arranged closer to the glass surface 10a.

   Although the heat transfer surface 32a of the present embodiment is a flat surface, the heat transfer surface 32a may be a convex surface along the concave shape of the glass surface 10a. That is, the heat transfer surface 32a may be a flat surface or a convex surface.

   As shown by a two-dot chain line in FIG. 2, a heat transfer sheet 9 may be disposed between the heat transfer surface 32a and the glass surface 10a. That is, the bracket 3 may have the heat transfer sheet 9 disposed between the heat transfer surface 32a and the glass surface 10a. One surface of the heat transfer sheet 9 contacts the glass surface 10a. The other surface of the heat transfer sheet 9 contacts the heat transfer surface 32a.

   The heat transfer sheet 9 is preferably a material having high flexibility and high thermal conductivity. The heat transfer sheet 9 is made of, for example, a silicone material. The heat transfer sheet 9 is attached to the heat transfer surface 32a using, for example, an adhesive.

   The curvature of the concave surface of the glass surface 10a differs for each vehicle type. For this reason, when attaching one kind of bracket 3 to vehicles 1 of various vehicle types, it is difficult to make the heat transfer surface 32a and the glass surface 10a adhere to each other. According to the present embodiment, the heat transfer sheet 9 is disposed between the heat transfer surface 32a and the glass surface 10a. Thereby, the heat transfer surface 32 a can be brought into close contact with the glass surface 10 a via the heat transfer sheet 9. That is, according to the present embodiment, a large contact area between the heat transfer surface 32a and the glass surface 10a via the heat transfer sheet 9 can be ensured, and the transfer of heat from the heat transfer surface 32a to the glass surface 10a is promoted. it can.

   The heat transfer section 32 has a lower surface 32b facing downward. The lower surface 32b is a surface facing the side opposite to the heat transfer surface 32a. The lower surface 32b faces the upper end surface 40a of the case 40. The lower surface 32b is a surface parallel to the upper end surface 40a. As shown in FIG. 3, the lower surface 32b faces the upper end surface 40a via the gap G. That is, the heat transfer member 31 and the sensor main body 4 are vertically opposed with the gap G therebetween. According to the present embodiment, by providing the gap G between the heat transfer member 31 and the sensor main body 4, the flexibility of positioning the sensor main body 4 with respect to the bracket 3 can be increased. As a result, the mounting angle of the sensor main body 4 with respect to the vehicle 1 can be adjusted, and the sensor main body 4 can be mounted in an appropriate posture on various types of vehicles. Further, according to the present embodiment, since the upper end surface 40a of the case 40 is exposed, heat of the sensor main body 4 can be radiated by heat radiation. That is, even if the lower surface 32b of the heat transfer section 32 and the upper end surface 40a of the case 40 are not in close contact with each other, the heat radiation effect by heat radiation can be enhanced.

FIG. 3 shows the upper end surface 140a of the modified example by a virtual line (two-dot chain line). The upper end surface 140a of the modified example is located above the upper end surface 40a. In this case, the lower surface 32b contacts the upper end surface 140a. In this modification, the heat transfer member 31 contacts the sensor main body 4. The heat of the sensor body 4 is transmitted to the heat transfer member 31 at a contact portion between the upper end surface 140a and the lower surface 32b.
In addition, another member having high thermal conductivity may be interposed between the upper end surface 140a and the lower surface 32b. In this case, the intervening other member can be regarded as a part of the case 40.
According to this modification, since the heat transfer member 31 contacts the upper end surface 140a of the sensor main body 4, heat can be efficiently transmitted from the sensor main body 4 to the heat transfer member 31. Therefore, according to the present embodiment, the heat of the sensor main body 4 can be efficiently transmitted to the glass surface 10a via the heat transfer member 31, and the heat can be effectively released from the sensor main body 4 to the glass surface 10a. it can.

As shown in FIG. 2, the eaves section 33 is located in front of the heat transfer section 32. The eaves portion 33 has a substantially triangular shape that becomes wider toward the front. The eaves section 33 is a flat plate that is not parallel to the heat transfer section 32. The eaves portion 33 extends on the front surface of the lens 45a. The eaves portion 33 has a shape whose width increases toward the front. With such a shape, the eaves portion 33 can ensure a sufficient angle of view of the imaging device 45 (for example, 100 °, at least 90 ° or more).
The eave portion 33 extends along the upper surface of the case 40. The eaves section 33 is connected to the heat transfer section 32 via the step section 34. According to the present embodiment, the provision of the eaves 33 on the heat transfer member 31 allows the heat generated by the sensor body 4 to be released to the outside via the eaves 33.
As shown in FIG. 3, the substrate 49 a disposed in the case 40 extends forward, and the front edge of the substrate 49 a reaches below the eaves 33. Further, an integrated circuit 49b that generates a large amount of heat as compared with other mounted components is mounted in a region in front of the substrate 49a. At least a part of the integrated circuit 49 b is located below the eaves portion 33. The eaves portion 33 releases the heat generated by the integrated circuit 49b to the outside.
As shown in FIG. 2, the width dimension W1 of the front end of the eave portion 33 is larger than the width dimension W2 of the front end of the sensor main body 4. Here, the width dimensions W1 and W2 are dimensions in the lateral direction D1. By making the width dimension W1 of the front end of the eaves section 33 sufficiently larger than the width dimension W2 of the front end of the sensor main body 4, an area in front of the sensor main body 4 can be covered with the eaves section 33. In the present embodiment, an integrated circuit 49b is arranged in a front area in the case 40. Since the eaves portion 33 covers the area in front of the sensor body 4 from above, the heat generated by the integrated circuit 49b by the eaves portion 33 can be efficiently radiated in the eaves portion 33.
Note that the shape of the eaves portion 33 is not limited to the present embodiment. The eaves portion 33 extends to the front surface of the lens 45a, and may adopt various other forms as long as the shape does not obstruct the field of view of the lens 45a.

   The step portion 34 is located between the heat transfer portion 32 and the eave portion 33 and connects the front edge of the heat transfer portion 32 and the rear edge of the eave portion 33. The rear edge of the eave portion 33 is located farther from the glass surface than the front edge of the heat transfer portion 32. Therefore, the step portion 34 has a shape that spreads in the up-down direction. When the eaves portion 33 is viewed in a plan view, the step portion 34 forms a part of the right and left sides of an isosceles triangle having the lens 45a as an apex. For this reason, the step 34 has an L-shape. At the center in the left-right direction of the step portion 34, a window portion 34a penetrating in the front-back direction is provided. The lens 45a of the sensor body 4 is exposed forward through the window 34a.

(Support member)
The support member 35 is made of a resin material. The support member 35 is formed by, for example, injection molding. In the present embodiment, the support member 35 is formed integrally with the heat transfer member 31. That is, the bracket 3 is manufactured by insert molding.

The support member 35 is fixed to the heat transfer member 31. The support member 35 is arranged adjacent to one edge (rear edge 31b) of the pair of edges 31a, 31b in the longitudinal direction D2 of the heat transfer member 31. The support member 35 is disposed adjacent to the pair of edges 31c and 31d of the heat transfer member 31 in the lateral direction D1. That is, the support member 35 surrounds the rear side and the left and right sides of the heat transfer member 31.
Note that the support member 35 may be disposed adjacent to one or both of the edges 31c and 31d of the heat transfer member 31 in the horizontal direction D1 and the edges 31a and 31b of the heat transfer member 31 in the vertical direction D2. .

   The support member 35 has a plate-shaped portion 36, a pair of first leg portions 37, and a pair of second leg portions 38.

   The plate portion 36 is a flat plate extending substantially parallel to the heat transfer portion 32. The plate portion 36 is substantially U-shaped in plan view. The plate portion 36 has a contact surface (contact portion) 36a facing the glass surface 10a. That is, the support member 35 has the contact surface 36a. The contact surface 36a contacts the glass surface 10a in a state where the bracket 3 is attached to the glass surface 10a.

   The contact surface 36a extends in the horizontal direction D1 and the vertical direction D2. In the present embodiment, the contact surface 36a is a plane parallel to the heat transfer surface 32a. The contact surface 36a is disposed on the glass surface 10a side with respect to the heat transfer surface 32a. That is, a step is provided between the contact surface 36a and the heat transfer surface 32a. The heat transfer surface 32a is located below the contact surface 36a. With the bracket 3 attached to the glass surface 10a, the heat transfer surface 32a and the contact surface 36a are arranged along the glass surface 10a.

   The contact surface 36a is disposed adjacent to one edge (rear edge) of the pair of edges in the vertical direction D2 of the heat transfer section 32 in a plan view. The contact surface 36a is arranged adjacent to a pair of edges in the lateral direction D1 of the heat transfer section 32 in a plan view. In the present embodiment, the contact surface 36a is a flat surface. However, the contact surface 36a may be a convex surface along the concave shape of the glass surface 10a.

   In the present embodiment, the support member 35 makes surface contact with the glass surface 10a at the contact surface 36a. However, the support member 35 may have a contact portion that contacts the glass surface 10a. The region where the contact portion (the contact surface 36a in the present embodiment) of the support member 35 contacts the glass surface 10a may be a plurality (three or more) points or a plurality (two or more) lines.

   An adhesive layer 39 is provided on the contact surface 36a. The support member 35 contacts the glass surface 10a via the adhesive layer 39. Thus, the support member 35 is fixed to the glass surface 10a. The adhesive layer 39 is, for example, an adhesive film.

   According to the present embodiment, since the support member 35 is made of a resin material, the bending rigidity is lower than when the support member 35 is made of a metal material. Therefore, by pressing the contact surface 36a against the glass surface 10a, the contact surface 36a is easily deformed according to the shape of the glass surface 10a. According to the present embodiment, the contact area and the adhesion area between the support member 35 and the glass surface 10a can be sufficiently ensured, and the fixing of the bracket 3 to the glass surface 10a can be stabilized.

   In the present embodiment, the case where the support member 35 is made of a resin material is exemplified. However, the material of the support member 35 is not limited as long as the bending rigidity of the plate portion 36 is sufficiently low and the contact surface 36a is deformed according to the shape of the glass surface 10a. As an example, the support member 35 may be a rubber material.

   As described above, the heat transfer surface 32a is provided on the plate-like heat transfer portion 32, and the contact surface 36a is provided on the plate-like plate portion 36. The heat transfer member 31 having the heat transfer surface 32a is made of a metal material, and the support member 35 having the heat transfer surface 32a is made of a resin material. For this reason, the plate-shaped portion 36 provided with the contact surface 36a has lower bending rigidity than the heat transfer portion 32 provided with the heat transfer surface 32a. That is, when a force in the direction of bending the heat transfer surface 32 a and the contact surface 36 a is applied to the bracket 3, the amount of bending of the support member 35 becomes larger than the amount of bending of the heat transfer member 31. Thereby, the contact area and adhesion area between the support member 35 and the glass surface 10a can be more effectively increased, and the fixing of the bracket 3 to the glass surface 10a can be stabilized.

   According to the bracket 3 of the present embodiment, the bracket 3 includes the heat transfer member 31 for dissipating the heat of the sensor main body 4 and the support member 35 for fixing to the glass surface 10a. For this reason, even if the glass surface 10a is a curved surface, the bracket 3 can be stably fixed to the glass surface 10a, and the heat generated by the sensor body 4 can be efficiently transmitted to the glass surface 10a.

   The first leg 37 and the second leg 38 project downward from the plate-like portion 36. The first leg 37 and the second leg 38 have a plate shape with the left-right direction being the plate thickness direction. The pair of first leg portions 37 are arranged symmetrically to each other in the bracket 3. Similarly, the pair of second leg portions 38 are arranged symmetrically to each other in the bracket 3. The second leg 38 is disposed rearward with respect to the first leg 37.

   As shown in FIG. 3, the first leg 37 is provided with a notch 37a that opens rearward and extends forward. The shaft 46 of the case 40 is inserted into the notch 37a. The second leg 38 is provided with a through hole 38a penetrating in the left-right direction. The claw portion 47 of the case 40 is inserted into the through hole 38a. The bracket 3 supports the sensor body 4 at the first leg 37 and the second leg 38.

   As described above, various embodiments of the present invention have been described. However, each configuration in each embodiment and a combination thereof are examples, and addition, omission, replacement, and addition of the configuration may be performed without departing from the gist of the present invention. Other changes are possible. For example, in the above embodiment, the sensor main body is a fusion type having a radar device and an imaging device, but is not limited to this. The sensor body may be of a type having only an imaging device without a radar device. Further, the present invention is not limited by the embodiments.
