Description

  The present invention relates to a power window switch device used for opening and closing an automobile window, and more particularly to a power window switch device in which two swingable operation knobs are arranged in parallel.

In a conventional general power window switch device, an operating member, a contact switching mechanism, and the like are incorporated in a space below an operation knob that can be swung, and when the operation knob is swung by an operator, The movable contact of the contact switching mechanism comes into contact with the fixed contact via the actuating member, and a predetermined electrical signal is output. In addition, since such a power window switch device is installed on the door of an automobile, rainwater or drinking water may enter the device through the opening of the case where the operation knob is exposed. Waterproofing measures are indispensable for the contact switching mechanism incorporated below. Therefore, conventionally, a sheet-like rubber projecting from a hollow convex portion that can be pressed by an actuating member is placed on a substrate on which a fixed contact or the like is disposed to cover the substrate, and a movable member provided in the hollow convex portion. When the contact knob is slidably opposed to the fixed contact on the substrate and the operating knob that has been oscillated pushes the hollow convex portion through the actuating member, the hollow convex portion is elastically deformed and the movable contact becomes a fixed contact. There is known a power window switch device configured to come into contact (see, for example, Patent Document 1).
Japanese Patent No. 3128443

  However, the above-described conventional power window switch device has a problem that it is difficult to reduce the thickness of the entire device because it is necessary to secure a space for installing an operation member, a contact switching mechanism, and the like below the operation knob. . In addition, when a plurality of operation knobs are arranged in parallel as in the power window switch device installed on the driver's side door, there is a problem that the assemblability is poor because the number of parts to be assembled on the board increases. . Further, if the waterproofing measures for protecting the contact switching mechanism are incomplete, short circuit accidents and poor continuity are likely to occur, and there is a problem that the reliability is easily lost due to deterioration of the waterproofing measures due to secular change.

  SUMMARY OF THE INVENTION The present invention has been made in view of such a state of the art, and an object of the present invention is to provide a power window switch device that can be easily reduced in thickness, can be improved in reliability, and can be easily assembled. It is in.

  In order to achieve the above object, a power window switch device according to the present invention includes a rotatable outer shaft, a first operation knob integrated with the outer shaft and swingable, and the outer shaft. A first object to be detected disposed at the end, an inner shaft that is inserted into the outer shaft and is rotatable, and a portion of the inner shaft that protrudes from the other end of the outer shaft. A second operation knob capable of swinging; a second object to be detected disposed at an end of the inner shaft; and a substrate disposed at a position facing the outer shaft and the end surface of the inner shaft. A case that is mounted on the substrate and has detection means that can individually detect rotational position information of the first and second detected bodies, and an opening that exposes the first and second operation knobs individually. The first operation knob and the second operation knob along the axial direction of the outer shaft and the inner shaft And the configuration that are arranged in parallel.

  In the switch device for a power window configured as described above, two operation knobs arranged in parallel are integrated with the outer shaft and the inner shaft, respectively, and when the first operation knob is swung, the outer shaft Since the first shaft and the first body to be detected rotate together and the second operation knob swings, the inner shaft and the second body to be detected rotate together. Based on the information, the swing operation position of each operation knob can be detected. In this power window switch device, the detection means for detecting each detected object and its rotational position information is disposed at the axial end portions of the outer shaft and the inner shaft. Since it is not necessary to incorporate parts, the entire apparatus can be easily reduced in thickness. In addition, since this power window switch device has each operation knob and each object to be detected integrated with the outer shaft or the inner shaft, and can be handled with the inner shaft inserted through the outer shaft during assembly, Although the unit structure has a plurality of operation knobs, good assemblability can be expected. In addition, this power window switch device has a special waterproof function because no parts are incorporated under each operation knob even when rainwater or drinking water enters the inside of the device through the opening of the case. Reliability is not impaired even if no measures are taken.

  In the above configuration, when the first and second objects to be detected are permanent magnets and the detecting means is a magnetoresistive element, high accuracy can be maintained even if dust or the like adheres, and performance deterioration due to wear or oxidation. Therefore, high reliability can be easily maintained over a long period of time. However, other non-contact type detection mechanisms such as an optical type and a capacity type may be employed, and a contact type detection mechanism having a movable contact may be employed.

  In the above configuration, the case supports the outer shaft and the inner shaft in a rotatable manner, and if a drain hole is provided at the bottom of the case, the bearing structure of the outer shaft and the inner shaft is simplified. In addition, rainwater, drinking water and the like that have entered from the opening of the case can be quickly discharged to the outside through the drain hole.

  Further, in the above configuration, when the first detection object and the second detection object are disposed on the one end side of the outer shaft and the inner shaft, respectively, each detection object and its rotational position information are displayed. Since the detection means to detect is concentrated and disposed at one end in the axial direction of the outer shaft and the inner shaft, the size in the axial direction can be reduced. Moreover, when it is set as a sealed structure, it can carry out efficiently.

  Further, in the above configuration, when the detection means is sealed and stored in the case, the output of the power window switch can be obtained more reliably.

  In the power window switch device of the present invention, two operation knobs arranged in parallel are integrated with the outer shaft and the inner shaft, respectively, and the detection means for detecting each detected object and its rotational position information is the outer shaft. Since it is disposed at the end of the inner shaft in the axial direction, it is not necessary to incorporate parts under each operation knob, and the entire apparatus can be easily reduced in thickness. Each operation knob and each object to be detected are integrated with the outer shaft or the inner shaft, and can be handled with the inner shaft inserted through the outer shaft during assembly. However, good assemblability can be expected. Even if rainwater, drinking water, etc. enters the inside of the device through the opening of the case, since no parts are incorporated under each operation knob, reliability is not required even if special measures are not taken. Is not impaired.

Of these, only the operation knob 1 is set so that a shallow swing operation and a deep swing operation can be performed in both pull and push. That is, when the operation knob 1 is shallowly pulled (or pushed), a manual closing operation (or opening operation) of the driver's side window can be performed, and the operation knob 1 is deeply pulled (or pushed). As a result, the window can be fully closed (or fully opened). The other operation knobs 2 to 4 are set so that only shallow swinging operation can be performed in both pull and push, and the operation knobs 2 to 4 are operated by pulling (or pushing) each operation knob 2 to 4. The window can be manually opened (or closed). Further, concave click grooves for engaging and disengaging convex portions such as click spring portions 19b to 22b, which will be described later, are formed on both side surfaces of the operation knobs 1 to 4. For example, the operation knob 1 capable of two-stage operation is formed with five click grooves 1a on each side surface, one for neutral position, two for pull operation, and two for push operation. The other operation knobs 2 to 4 are formed with three click grooves on each side surface, one for neutral position, one for pull operation, and one for push operation. A part of each click groove is not shown.

It has been.

  As shown in FIG. 2 and FIGS. 7 to 9, the leaf springs 19, 20, 21, and 22 return to their initial positions after operating the operation knobs 1, 2, 3, and 4 that have been operated to swing in the pull direction. The return spring portions 19a, 20a, 21a, and 22a are formed to extend, and the click spring portions 19b, 20b, 21b, and 22b having convex portions are formed as standing pieces. Each of the click spring portions 19b to 22b is for causing the convex portion to engage and disengage with a click groove provided on one side surface of the operation knobs 1 to 4, thereby generating a click feeling. FIG. 8 shows a state of the neutral position of the operation knob 1 that can be operated in two steps, in which the convex portion 19c of the click spring portion 19b enters the click groove 1a indicated by a broken line. From this state, for example, when the operation knob 1 is swung shallowly in the pull direction, the convex portion 19c of the click spring portion 19b enters the click groove 1a indicated by the broken line in FIG. Although illustration is omitted, when the operation knob 1 is swung deeply in the pull direction, the convex portion 19c enters the click groove 1a and a click feeling is generated. In both cases of the shallow swing operation and the deep swing operation in the pull direction, the operation knob 1 is pushed back to the initial position by the elastic force of the return spring portion 19a after the operation. Further, when the operation knob 3 is swung in the pull direction (see FIG. 9), the convex portion 21c of the click spring portion 21b enters the click groove 3a indicated by the broken line in FIG. After the operation, the operation knob 3 is pushed back to the initial position by the elastic force of the return spring portion 21a. The operation when the operation knobs 2 and 4 are swung in the pull direction is the same as that of the operation knob 3. Although not shown, each of the operation knobs 1 is provided with another four leaf springs provided with return spring portions for returning the operation knobs 1 to 4 that have been swing-operated in the push direction to their initial positions after operation. It is arrange | positioned on the lower surface side of the other side on both sides of the rotation center of -4.

  The outer shaft 6 is formed in a substantially cylindrical shape, and one end portion on the printed circuit board 10 side is a semi-cylindrical portion by a notch 6a (see FIG. 4), and is formed on the outer peripheral surface of the semi-cylindrical portion. A permanent magnet 11 is fixed. An operation knob 1 is integrated with the outer shaft 6 by external fitting or the like. When the operation knob 1 is swung, the outer shaft 6 also rotates integrally. The inner shaft 7 is formed in a substantially cylindrical shape, and one end portion on the printed circuit board 10 side is exposed to the notch 6a of the outer shaft 6, and the permanent magnet 12 is fixed to the outer peripheral surface of the exposed portion. Yes. The inner shaft 7 is longer than the outer shaft 6, and about half of the inner shaft 7 near the printed circuit board 10 is inserted into the outer shaft 6. The remaining portion of the inner shaft 7 is the other end of the outer shaft 6. Protruding from. The operation knob 2 is integrated with the protruding portion of the inner shaft 7 by external fitting or the like. When the operation knob 2 is swung, the inner shaft 7 also rotates integrally. The outer shaft 6 and the inner shaft 7 can be rotated independently of each other. Further, in both the permanent magnet 11 and the permanent magnet 12, the direction perpendicular to the paper surface of FIG. 3 is the magnetization direction, and when the operation knobs 1 and 2 are not operated to swing, the permanent magnet 11 and the permanent magnet 12 are shown in FIGS. As described above, the permanent magnets 11 and 12 are arranged at positions separated by about 180 degrees in the vertical direction.

  The outer shaft 8 has the same shape as the outer shaft 6, and a permanent magnet 15 is fixed to the outer peripheral surface of one end portion on the printed board 10 side. The operation knob 3 is integrated with the outer shaft 8, and when the operation knob 3 is swung, the outer shaft 8 also rotates integrally. The inner shaft 9 has the same shape as the inner shaft 7, and a permanent magnet 16 is fixed to the outer peripheral surface of one end portion on the printed circuit board 10 side. An operation knob 4 is integrated with the inner shaft 9, and when the operation knob 4 is swung, the inner shaft 9 also rotates integrally. The mutual positional relationship between the outer shaft 8 and the inner shaft 9 is the same as the mutual positional relationship between the outer shaft 6 and the inner shaft 7. Further, the magnetization direction of the permanent magnets 15 and 16 and the mutual positional relationship are the same as the magnetization direction of the permanent magnets 11 and 12 and the mutual positional relationship.

  The printed circuit board 10 is formed in a horizontally long and low-profile rectangular shape, and faces one end face of each of the outer shafts 6 and 8 and the inner shafts 7 and 9. As shown in FIG. 5 and FIG. 6, a magnetoresistive element 13 and a permanent magnet 12 that can be opposed to the permanent magnet 11 are disposed around a region of the printed board 10 that faces one end surface of the outer shaft 6 and the inner shaft 7. The opposing magnetoresistive element 14 is mounted in a vertically distributed manner. Similarly, a magnetoresistive element 17 that can face the permanent magnet 15 and a magnetoresistive element 18 that can face the permanent magnet 16 are disposed around a region of the printed circuit board 10 that faces the one end surfaces of the outer shaft 8 and the inner shaft 9. And are implemented by sorting them up and down. These magnetoresistive elements 13, 14, 17, and 18 are giant magnetoresistive elements, so-called GMR elements (Giant Magneto Resistance Elements). However, an AMR element (Anisotropy Magneto Resistance Element) may be used as the magnetoresistive element.

  In the power window switch device configured as described above, when the operation knobs 1 to 4 are swung, the outer shaft 6, the inner shaft 7, the outer shaft 8 and the inner shaft 9 rotate integrally to become permanent. Since the positions of the magnets 11, 12, 15, 16 change, the direction of the magnetic field acting on the magnetoresistive elements 13, 14, 17, 18 changes, and the magnetoresistive elements 13, 14, 17, 18 accompanying this magnetic field change. The swing operation position of the corresponding operation knob 1, 2, 3, 4 can be detected based on the change in resistance value. For example, when the operation knob 1 is swung, the outer shaft 6 and the permanent magnet 11 rotate integrally to change the direction of the magnetic field of the permanent magnet 11 acting on the magnetoresistive element 13. Based on the output voltage, the swing operation position of the operation knob 1 can be detected. When the operation knob 2 is swung, the inner shaft 7 and the permanent magnet 12 rotate integrally to change the direction of the magnetic field of the permanent magnet 12 that acts on the magnetoresistive element 14. Based on the output voltage, the swing operation position of the operation knob 2 can be detected. The swing operation position of the operation knobs 3 and 4 can also be detected by the same operation principle. 6 shows the rotational positions of the permanent magnets 11, 12, 15, 16 with respect to the magnetoresistive elements 13, 14, 17, 18 when the operation knobs 1 to 4 are pulled. The swing angle is about 30 degrees because it is in a deep pull operation, but the swing angles of the other operation knobs 2 to 4 are about 15 degrees.

  Each of the operation knobs 1 to 4 is formed with a plurality of click grooves, and when not operated, each operation knob 1 to 4 engages a corresponding click spring portion 19b to 22b or the like with a predetermined click groove. Therefore, it is supported stably. When the operation knobs 1 to 4 are operated to swing, the convex portions of the corresponding click spring portions enter into another click groove to cause a click feeling, so that the operator can operate the operation knobs 1 to 4 in a predetermined manner. It can be sensed with the fingers that the swing operation position has been reached. When the operation force is removed, the operation knobs 1 to 4 are automatically urged by the corresponding return spring portions 19a to 22a and the like to automatically return to the initial position. Further, when the operation knobs 1 to 4 reach a predetermined swing operation position, a desired window opening / closing operation is performed based on the electric signals output from the corresponding magnetoresistive elements 13, 14, 17, and 18. It has become.

  As described above, in the power window switch device according to this embodiment, the permanent magnet 11 is fixed to one side of the outer shaft 6 integral with the operation knob 1 and the outer shaft 6 integral with the operation knob 2. The permanent magnet 12 is fixed to one side portion of the inner shaft 7 inserted through the inner shaft 7, and the rotational position information of the permanent magnets 11 and 12 can be detected by the magnetoresistive elements 13 and 14, respectively. The swing operation position of the two operation knobs 1 and 2 can be detected based on the output voltage of the magnetoresistive elements 13 and 14. Similarly, the swing operation position of the two operation knobs 3 and 4 arranged in parallel can be detected based on the output voltage of the magnetoresistive elements 17 and 18. Further, since the permanent magnets 11 and 12 and the magnetoresistive elements 13 and 14 are concentrated on one end side in the axial direction of the outer shaft 6 and the inner shaft 7, it is not necessary to incorporate parts below the operation knobs 1 and 2. Similarly, since the permanent magnets 15 and 16 and the magnetoresistive elements 17 and 18 are concentrated on one end side in the axial direction of the outer shaft 8 and the inner shaft 9, it is not necessary to incorporate components below the operation knobs 3 and 4. . Therefore, the power window switch device can be easily thinned as a whole.

  Further, in the power window switch device according to this embodiment, the operation knobs 1 and 2 and the permanent magnets 11 and 12 are integrated with the outer shaft 6 or the inner shaft 7, and the inner shaft 7 is moved to the outer shaft during assembly. 6 can be handled in a state where it is inserted through 6. Similarly, the operation knobs 3 and 4 and the permanent magnets 15 and 16 are integrated with the outer shaft 8 or the inner shaft 9 and can be handled in a state where the inner shaft 9 is inserted into the outer shaft 8 during assembly. The assembly process will be described in detail. First, permanent magnets 11 and 12 are fixed to the outer shaft 6 and the inner shaft 7, respectively, and the inner shaft 7 is inserted from one end side of the outer shaft 6 to form a shaft unit. Next, in this state, the operation knobs 1 and 2 are inserted from the other end sides of the outer shaft 6 and the inner shaft 7, and these are fixed to a predetermined position to create an operation knob unit. In addition, electrical components such as the magnetoresistive elements 13 and 14 are mounted on the printed circuit board 10 and are held by the upper case 51 to form an upper case unit. Next, the operation knob unit is assembled so that the other end of the inner shaft 7 is inserted into the bearing hole of the upper case 51 from the bottom surface of the upper case unit, and the outer shaft 6 is positioned at the bearing portion of the upper case 51. Thereafter, the leaf springs 19 and 20 are attached to the upper case 51, and finally the lower case 52 is attached to the upper case 51. The upper case 51 is formed with a notch into which the outer shaft 6 can be inserted. The lower case 52 is incorporated into the upper case 51 to support the outer shaft 6 from below and hold it rotatably. The outer shaft 8 and the inner shaft 9 on the operation knobs 3 and 4 side are assembled in the same procedure. Therefore, this power window switch device has a good assembly while having a unit structure having four operation knobs 1 to 4.

  In addition, the power window switch device according to the present embodiment is provided below the operation knobs 1 to 4 even when rainwater or drinking water enters the device via the openings 5a to 5d of the case 5. Since no parts are incorporated and the drain hole 5e is provided at the bottom of the case 5, the intruded moisture can be quickly discharged to the outside, and the reliability is not impaired. Moreover, since it is not necessary to take special waterproof measures, it is easy to reduce the cost. Further, since the case 5 is provided with a plurality of bearing portions 5f for rotatably supporting the outer shafts 6, 8 and the inner shafts 7, 9, the bearing structure of the outer shafts 6, 8 and the inner shafts 7, 9 is provided. In this respect, it is easy to reduce the cost.

  Further, in the power window switch device according to the present embodiment, as shown in FIGS. 2 and 3, the permanent magnet and the magnetoresistive element are sealed with a case. Therefore, even when it is not possible to completely drain the water through the drain hole, it is possible to reliably obtain a predetermined electrical signal output. In addition, the frictional force between the return spring (plate spring), click groove and bearing can stably maintain the posture of the operation knob in the neutral position, and a pair of operations integrated with the inner shaft and the outer shaft. When one of the knobs is swung, the other operation knob is prevented from rotating together, and both operation knobs can be operated independently.

  In the above embodiment, the rotational position information of the permanent magnets 11 and 12 is individually detected by the magnetoresistive elements 13 and 14, but the rotational position of the permanent magnets 11 and 12 is detected by one magnetoresistive element. It is also possible to detect information. Similarly, the rotational position information of the permanent magnets 15 and 16 can be detected by one magnetoresistive element.

  In the above embodiment, a magnetic detection mechanism is used in which the rotational position information of the permanent magnet that rotates in conjunction with the operation knob is detected by the magnetoresistive element. However, other non-contact detection mechanisms are used. For example, an optical type or a capacitive type may be employed, and a contact type detection mechanism having a movable contact may be employed. However, if the detection mechanism is magnetic, there is an advantage that high accuracy can be maintained even if dust or the like adheres, and performance deterioration due to wear or oxidation can be avoided.

  Further, in the above embodiment example, since permanent magnets and magnetoresistive elements are concentrated and arranged on each end side of the inner shaft and the outer shaft, the axial dimension can be reduced. These permanent magnets and magnetoresistive elements and the outer shaft permanent magnets and magnetoresistive elements may be arranged separately on both ends in the axial direction.
