  However, there is a problem that it is difficult to manage the pressing force of the operator who presses the case against the window glass when the humidity detection device described in Patent Document 1 is attached to the window glass. This is because the pressing force for pressing the case against the window glass differs depending on the force applied by the operator attaching the humidity detecting device to the window glass.

As a result, the humidity detecting device may be detached from the window glass. On the other hand, when the pressing force of the operator is excessive than the pressing force necessary for bonding the case and the window glass, the excessive pressing force is likely to be applied to the case. As a result, there is a possibility that problems such as deformation of the case, damage to the window glass, and the vehicle may occur.

The claw portion 132 protrudes toward the upper case 110 in a direction orthogonal to the plane of the base portion 131, that is, in a direction orthogonal to the plane of the window glass 101. The thickness of the claw 132 is the same as the thickness of the base 131 and is thin. The claw portion 132 is inserted into the upper case 110 from the communication port 110h of the upper case 110, and is accommodated in the accommodation groove 111f via the communication port 110h.

  As shown in FIG. 4, the claw portion 132 has a notch portion 132 a. The notch portion 132 a is formed so as to cut out the claw portion 132 on the side opposite to the connector 164, that is, the insertion port 110 f side in the upper case 110. Therefore, the nail | claw part 132 is formed in C shape by the notch part 132a. An inclined guide surface 132b is formed on the inner surface of the claw portion 132 on the upper case 110 side of the notch portion 132a, and a part of a locking member 150 described later is guided to the back of the notch portion 132a. It has become.

  An adhesive sheet 134 is attached to the fixing member 130 on the opposite side of the upper case 110, and the fixing member 130 is bonded to the window glass 101 with the adhesive sheet 134. The adhesive sheet 134 is attached and fixed to the fixing member 130 on, for example, an upper portion of a window mirror (not shown) of the window glass 101. In the present embodiment, a double-sided adhesive sheet having a thickness of about 0.5 mm is used as the adhesive sheet 134. The adhesive sheet 134 has substantially the same shape as the base 131 of the fixing member 130. By using the adhesive sheet 134, the fixing member 130 can be easily attached and fixed at an appropriate position of the window glass 101.

  Here, the adhesive sheet 134 is slightly thinner than the glass-side heat conductive sheet 161c surrounded by the adhesive sheet 134, as shown in FIG. Therefore, the glass side heat conductive sheet 161c is slightly raised from the adhesive sheet 134, and when the fixing member 130 is attached to the window glass 101, the glass side heat conductive sheet 161c is surely pressed against the glass surface. (See FIG. 9). According to this, even when the adhesion of the glass side heat conductive sheet 161c is not sufficient, it is possible to prevent a problem that the glass side heat conductive sheet 161c is displaced and dropped.

  The leaf spring 140, which is an elastic member, is bent in the same direction at both ends, and is formed in a substantially V shape. Both ends of the leaf spring 140 urge the ceiling wall 110a of the upper case 110. The center of the leaf spring 140 urges the surface on the ceiling wall 110 a side (counter circuit board 122 side) of the bridge portion 121 b of the pressing portion 121. The leaf spring 140 is fixed to the pressing portion 121 by the engagement of the engagement hole 141 formed in the leaf spring 140 with the engagement protrusion 121 d formed in the bridge portion 121 b of the pressing portion 121. ing. Accordingly, the leaf spring 140 cannot move in the plane direction of the window glass 101 in the assembled state of the humidity detecting device 100 to the window glass 101. The leaf spring 140 and the glass temperature sensor 161a are disposed on the same axis.

  FIG. 7 is a perspective view of the locking member 150 according to the present embodiment as viewed from the other side. The locking member 150 serving as locking means is disposed at a position where it engages with the insertion port 110 f and engages with the guide groove 111 of the upper case 110 and the claw portion 132 of the fixing member 130. The locking member 150 is formed into a U shape by resin. Specifically, the U-shape is a design wall portion 151 of the design portion having the same shape as the insertion port 110f of the upper case 110, and is formed as a sliding portion at both ends of the design wall portion 151. And a pair of guide groove sliding portions 152 extending in the direction.

Furthermore, a rib 154 for improving the strength of the design wall 151 is formed on the inner surface of the design wall 151 along the longitudinal direction of the slit 153.

  The guide groove sliding portion 152 is inserted into the guide groove 111 of the upper case 110, and includes a thin shallow groove sliding portion 152a and a thick deep groove sliding portion 152b. The shallow groove sliding portion 152a has the appearance of the guide groove sliding portion 152, and has an elongated shape that is substantially the same length as the length of the guide groove 111 in the extending direction. The shallow groove sliding portion 152a is inserted into the shallow groove 111d of the upper case 110, and has a thickness substantially the same as the depth of the shallow groove 111d. The shallow groove sliding portion 152a is formed slightly smaller than the groove width of the shallow groove 111d.

  Deep groove sliding portions 152b are formed on the outer surfaces of the pair of shallow groove sliding portions 152a, respectively. Two deep groove sliding portions 152b are formed to protrude on the outer surface of the pair of shallow groove sliding portions 152a. The deep groove sliding portion 152b is an elongated shape extending in the extending direction of the guide groove 111, and is formed to have a thickness substantially the same as the depth of the deep groove 111e. The bottom surface (surface on the fixing member 130 side) of the shallow groove sliding portion 152a and the bottom surface (surface on the fixing member 130 side) of the deep groove sliding portion 152b are continuous. The deep groove sliding part 152b is formed slightly smaller than the groove width of the deep groove 111e, and the width of the notch part 132a formed in the claw part 132 of the fixing member 130 (perpendicular to the insertion direction of the locking member 150). The dimension is slightly smaller than the dimension in the direction of The deep groove sliding portion 152b is inserted into the notch portion 132a of the claw portion 132 housed in the housing groove 111f of the upper case 110. The formation position of the deep groove sliding portion 152b in the guide groove sliding portion 152 is a position where the deep groove sliding portion 152b can be inserted into the cutout portion 132a accommodated in the accommodation groove 111f. The distal end of the deep groove sliding portion 152b in the insertion direction is rounded. Specifically, the front end surface 152c on the upper case 110 side in the insertion direction of the deep groove sliding portion 152b has an inclined shape as shown in FIG. 4 so as to be easily engaged with the notch portion 132a. Yes. Here, the guide groove 111, the claw portion 132, and the guide groove sliding portion 152 correspond to a pressing mechanism.

  Next, a system configuration of electrical control of the humidity detection apparatus 100 in the present embodiment will be described with reference to FIG. FIG. 5 is an electrical block diagram of the humidity detection apparatus 100 in the present embodiment.

  First, the output signals of the various sensors 161 a, 162, and 163 are amplified by the amplifier 166 and applied to the various arithmetic circuits 167. The various calculation circuits 167 are a relative humidity calculation circuit 167a, an air temperature calculation circuit 167b, a glass temperature calculation circuit 167c, and a glass surface relative humidity calculation circuit 167d. The glass surface relative humidity calculation circuit 167d is an operation for calculating the glass surface relative humidity based on the calculation value of the relative humidity calculation circuit 167a, the calculation value of the air temperature calculation circuit 167b, and the calculation value of the glass temperature calculation circuit 167c. Circuit. The calculated value of the glass surface relative humidity calculation circuit 167d is output to the air conditioning ECU 102 of the air conditioning control device through the communication circuit 168. According to this, since the window glass surface relative humidity directly connected to the fog of the window glass 101 can be calculated, the calculated value of the surface relative humidity in the window glass 101 is used to optimally control the fog prevention of the air conditioner. Can be executed. Here, the various calculation circuits 167 correspond to glass surface relative humidity calculation means.

  Next, an attaching process for attaching the humidity detecting device 100 in this embodiment to the window glass 101 will be described with reference to FIGS. 9 to 11. 9 and 10 are longitudinal sectional views of the humidity detection device 100 in the present embodiment. FIG. 11 is a perspective view showing a method for attaching the humidity detecting device 100 to the window glass 101 in the present embodiment.

  First, as a pre-process for attaching the humidity detecting device 100 to the window glass 101, a circuit board 122 to which a connector 164 is fastened by a screw (not shown), a lower case 123 to which a metal member 161b is attached, and a pressing portion 121 are provided. Prepare and assemble the member 120 to be stored. That is, the column part 121 a of the holding part 121, the circuit board 122, and the lower case 123 are fastened and fixed by the screws 124. At this time, the member 120 to be stored is assembled with the sensor-side heat conductive sheet 161d sandwiched between the glass temperature sensor 161a of the circuit board 122 and the metal member 161b of the lower case 123. Specifically, it is assembled so that the glass temperature sensor 161a is pressed to such an extent that it is slightly recessed into the sensor side heat conductive sheet 161d.

  Next, the leaf spring 140 is sandwiched between the bridge portion 121 b of the holding portion 121 and the ceiling wall 110 a of the upper case 110 that constitute the member 120 to be stored, and the engagement of the holding portion 121 in the engagement hole 141 of the leaf spring 140. The mating protrusion 121d is engaged, and the member 120 to be stored is stored in the upper case 110. Here, since the humidity detection apparatus 100 does not include a fastening means such as a screw for fastening the upper case 110 and the member 120 to be stored, the member 120 stored in the upper case 110 is restrained by the upper case 110. It is in a state where the position can be moved. However, since the shape of the lower case 123 is similar to the storage port 110e of the upper case 110 and is slightly smaller than the storage port 110e, the shape of the lower case 123 is restricted by the edge of the storage port 110e, and the opening of the storage port 110e It does not move along the surface. The member 120 to be accommodated can be moved in the direction of contacting and separating from the ceiling wall 110a of the upper case 110 by applying a load to the leaf spring 140 and elastically deforming it.

  Moreover, the glass side heat conductive sheet 161c is stuck on the window glass 101 side surface of the metal member 161b in the lower case 123. In a state where the leaf spring 140 is not elastically deformed, the glass-side heat conductive sheet 161 c protrudes from the upper case 110. The amount of protrusion, which is the amount that the glass-side heat conductive sheet 161 c protrudes from the upper case 110, is greater than the sum of the thickness of the base 131 of the fixing member 130 and the thickness of the adhesive sheet 134 when bonded. In this manner, a component in which the member to be stored 120 and the leaf spring 140 are stored is prepared for the upper case 110.

  As an explanation of the attachment process, first, as a preparation for attaching the upper case 110 in which the member 120 is accommodated to the window glass 101, the fixing member 130 is attached to the window glass 101 as shown in FIG. Paste with. The pressing force P when the fixing member 130 is attached to the window glass 101 is a pressing force that does not damage the window glass 101, and the upper case 110, the member to be stored 120, and the leaf spring 140 with respect to the fixing member 130. Even if the locking member 150 is attached, it is sufficient that the humidity detecting device 100 assembled by these members has a pressing force that does not detach from the window glass 101. In other words, the pressing force P is smaller than the pressing force P1 that causes the window glass 101 to break, and is larger than the pressing force P2 that causes the humidity detecting device 100 to be detached from the window glass 101 when the humidity detecting device 100 is attached to the window glass 101. It ’s fine. In terms of mathematical expressions, P2 <P <P1. The range of the pressing force P is very wide, so that even if the workers who stick the fixing member 130 to the window glass 101 are different, all workers can be pasted with the pressing force within the range. .

  And the upper case 110 which accommodated the to-be-stored member 120 is joined to the fixing member 130 fixed to the window glass 101 like FIG.11 (b). First, the claw portion 132 of the fixing member 130 is inserted into the accommodation groove 111 f of the upper case 110 from the communication port 110 h. The inserted claw portion 132 is guided to the back of the upper case 110 by the side surface of the housing groove 111f. And until the glass side heat conductive sheet 161c contacts the window glass 101, the nail | claw part 132 is inserted in the accommodation groove | channel 111f, and a joining process is carried out by the glass side heat conductive sheet 161c and the window glass 101 contacting. Completed state.

  Next, the locking member 150 is inserted into the upper case 110 from the insertion port 110f in a state where the glass-side heat conductive sheet 161c and the window glass 101 are in contact with each other. Specifically, the shallow groove sliding portion 152a of the locking member 150 is inserted into the shallow groove 111d of the upper case 110 from the insertion port 110f. The shallow groove sliding portion 152a is guided to the side surface (groove bottom) of the shallow groove 111d and inserted into the depth of the shallow groove 111d. When the shallow groove sliding portion 152a is inserted into the shallow groove 111d, the deep groove sliding portion 152b is inserted into the deep groove 111e of the upper case 110 from the insertion port 110f. The deep groove sliding part 152b is guided to the side surface (groove bottom) of the deep groove 111e and inserted into the back. Then, when the locking member 150 is slid into the upper case 110 along the plane direction of the window glass 101, the front end surface 152 c of the deep groove sliding portion 152 b becomes the guide surface 132 b of the claw portion 132 of the fixing member 130. Contact. That is, when the leaf spring 140 is not elastically deformed, the deep groove sliding portion 152b is not inserted into the notch portion 132a of the claw portion 132. FIG. 9 shows a longitudinal sectional view of the humidity detecting device 100 in a state where the locking member 150 is inserted partway through the guide groove 111 after the joining step. 11B also shows a perspective view of the humidity detection device 100 in this state.

  Further, when the locking member 150 is pushed into the upper case 110 in a state where the distal end surface 152c of the deep groove sliding portion 152b and the guide surface 132b of the claw portion 132 are in contact, the deep groove sliding portion 152b is inclined to the inclined tip. The surface 152c is guided by the guide surface 132b and moves to the back of the notch 132a. When the deep groove sliding portion 152b is inserted into the notch 132a, the bottom surface of the shallow groove sliding portion 152a on the window glass 101 side is pressed against the inner surface of the shallow groove 111d on the window glass 101 side. The upper case 110 pressed against the window glass 101 side by the groove inner surface of the shallow groove 111d is pressed against the window glass 101 side.

  The upper case 110 is pressed against the window glass 101 and presses the member to be stored 120 against the window glass 101 via the leaf spring 140. Here, since the glass-side heat conductive sheet 161c is in contact with the window glass 101, the member to be stored 120 is pressed against the window glass 101 side at the deformation amount ΔT1 of the glass-side heat conductive sheet 161c. Move. That is, the difference between the amount of movement ΔT1 of the upper case 110 toward the window glass 101 and the amount of movement ΔT2 of the member 120 to be stored toward the window glass 101 becomes the deformation amount ΔT of the leaf spring 140. Expressed numerically, ΔT1−ΔT2 = ΔT.

  The leaf spring 140 presses the member to be stored 120 against the window glass 101 based on the deformation amount ΔT. The locking member 150 has the design wall portion 151 of the locking member 150 attached to the insertion port 110f of the upper case 110, and the outer surface of the design wall portion 151 and the outer surfaces of the side walls 110b to 110d of the upper case 110 are surfaces. It will be in the state where the attachment process was completed when it inserts in the upper case 110 until it becomes 1, and the design wall part 151 contacts the insertion port 110f. FIG. 10 shows a longitudinal sectional view of the humidity detecting device 100 in a state after the assembling process. FIG. 11C also shows a perspective view of the humidity detection device 100 in this state.

In the humidity detection device 100 according to the present embodiment, first, the pressing force P at the time of preparation for attaching the fixing member 130 to the window glass 101 is removed from the window glass 101 when the humidity detection device 100 is attached to the window glass 101. What is necessary is just to be larger than the pressing force P2 to be released and smaller than the pressing force P1 that causes the window glass 101 to break. Further, when the upper case 110 is attached to the fixing member 130, the upper case 110 is attached by the locking member 150 that is locked to the fixing member 130, so that the upper case 110 is not pressed toward the window glass 101. As a result, it is possible to provide the humidity detection device 100 in which the glass temperature sensor 161a is fixed at a position where the surface temperature of the window glass 101 can be reliably detected even if the workers are different.
