Description

  The present invention is used in an input operation unit that performs power on / off of various electronic devices, selection of functions, adjustment of control values, execution of functions, and the like, such as rotation operation and / or tilting operation of an operation shaft, pressing operation, etc. The present invention relates to a composite operation type switch capable of realizing an operation.

  In recent years, in order to enhance the convenience and comfort of the driver, a car navigation device, a car air conditioner, a multi-function meter panel, etc. are often mounted. Multi-functionality that can realize a plurality of operations such as function selection and function execution with a single switch. For example, a compound operation type switch as described in Patent Document 1 is an instrument panel that is easy for a driver to operate. , May be provided near the steering wheel.

Such a composite operation type switch is advantageous in that a plurality of operations such as a rotation operation, a tilting operation, and a pressing operation can be input by one device, but a rotating operation, a tilting operation, and a pressing operation are realized by one device. In this case, the knob operated by the driver and the knob holder that is rotatable in the rotation direction, tiltable in the tilting direction, and slidable in the pressing operation direction, and the rear face in accordance with the operation in the pressing direction of the knob.

Japanese Patent Laid-Open No. 10-50178

  However, in such a composite operation type switch, for example, when the knob is tilted by tilting up and down and pushed, that is, pressed, for example, a three-way composite operation type switch, there is a gap between the knob holder and the knob. In particular, when such a composite operation type switch is provided in a place where it is easy for the driver to operate, the guide length necessary for the pressing operation may not be sufficiently obtained, Due to restrictions, there may be cases where the joint surface between the knob, knob holder, and pusher cannot be secured sufficiently, and grease application or preloading for friction reduction may not be performed sufficiently. This causes a problem that the driver feels uncomfortable.

  In view of the above problems, an object of the present invention is to provide a composite operation type switch that suppresses rattling when the driver operates the knob and prevents the driver from feeling uncomfortable in operation. To do.

In order to solve the above problem, the composite operation type switch according to the present invention is:
Knob,
A knob holder for holding the knob rotatably or / and tiltably;
A pusher that constitutes a contact in accordance with the pressing operation of the knob;
With
The shape on the back side of the knob as viewed from the tilt center includes a string connecting a circular shape and two points on the circumferential direction of the circular shape,
The string is inclined with respect to the bottom surface on the front side of the pusher.

  In addition, the shape on the back side of the knob only needs to satisfy the shape defined by the shape seen from the tilt center. In the perspective view seen from the direction tilted from the tilt center, for example, the circular shape May constitute a cylindrical shape, and the string may constitute an inclined surface formed by cutting the cylindrical shape into a flat shape, or the circular shape may constitute a spherical shape, and the string may form the spherical shape You may comprise the inclined surface formed by cutting in flat form. The shape of the pusher on the front side is a flat bottom surface.

  Further, the front side is the front side when viewed from the driver, and the back side is the back side when viewed from the driver. Further, the fact that the string included in the shape on the back side of the knob is inclined with respect to the bottom surface on the front side of the pusher means that the pressing operation is not performed and the knob is not in contact with the pusher. Make provisions for mutual positional relationships in stages.

  According to this, particularly when the knob is pressed by the driver, the shape of the back side of the knob comes into contact with the bottom surface of the front side of the pusher. First, the end opposite to the side inclined with respect to the bottom surface is in contact, and in the final contact stage, the entire string contacts the bottom surface on the front side of the pusher.

  For this reason, the posture of the knob in the tilting direction and the posture in the rotational direction are stabilized. This can prevent the knob from rattling.

  Furthermore, based on the geometric relationship between the string formed on the back side of the knob and the bottom surface formed on the front side of the pusher, rattling of the knob is prevented. For example, even when there is a high demand for installing the composite operation type switch near the steering wheel that is easy for the driver to operate, the guide length cannot be long, there are design restrictions, preload cannot be secured, grease It is also possible to eliminate the problem that rattling occurs due to the fact that the coating cannot be applied.

  According to the composite operation type switch of the present invention, it is possible to suppress rattling when the driver operates the knob, and to prevent the driver from feeling uncomfortable in operation.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a schematic view showing an embodiment of a composite operation type switch according to the present invention. FIG. 2 is a schematic cross-sectional view showing an embodiment of the composite operation type switch according to the present invention in a cross-section parallel to the vertical direction through the center in the left-right direction of the knob. FIG. 3 is a schematic cross-sectional view showing a part of one embodiment of the composite operation type switch according to the present invention in a cross section passing through the center of the knob in the horizontal direction and parallel to the vertical direction.

  For example, as shown in FIG. 1, the composite operation type switch 1 of this embodiment selects and executes functions by two kinds of operations, that is, an up / down tilting operation by up / down toggle and a pressing operation by a forward / backward direction, that is, a pressing operation. As shown in FIG. 2, the switch includes a knob 2, a knob holder 3, a pusher 4, a guide 5, and a cover 6.

  The cross section perpendicular to the left-right direction shown in FIG. 2 also shows a left-right direction view of the knob 2, the knob holder 3, and the pusher 4 as viewed from the tilt center of the knob 2, and the front side indicated by F in FIG. A bell-shaped shape 2a whose vertical width decreases from the front to the front is formed, and on the back side opposite to F in FIG. 2, the bell-shaped shape 2a is finished and widened in the vertical direction on the back side. A semi-cylindrical shape 2c centered in the left-right direction is provided so that it can be tilted to the center of tilting in the left-right direction after the collar portion 2b is finished toward the back side. The semi-cylindrical shape 2c has a circular shape in the cross section shown in FIG.

  The knob 2 is supported by the semi-cylindrical shape 2c of the knob 2 itself, the knob holder 3 and the guide action of the guide 5 so that the knob 2 can be tilted about the tilt center and can be pressed from the front side to the back side as indicated by F in FIG. Is done. Further, the deviation of the knob 2 toward the front side is prevented by the holding action of the flange portion 2b of the knob 2 and the knob holder 3.

  The pusher 4 is supported by the guide action of the guide 5 so as to be slidable in the pressing operation direction. After the pusher 4 is inserted into the guide 5 and the knob 2 and the knob holder 3 are assembled from the front side, the cover 6 is fitted to the guide 5 to ensure appearance and design from the front side. Can be assembled.

  Further, as shown in FIG. 3, the shape of the back side of the knob 2 includes the semi-cylindrical shape 2c described above, and is viewed from the tilting center direction of the knob 2 extending from the front side to the back side in the right side view of FIG. In addition, the shape of the back side of the knob 2 is a semi-cylindrical shape 2c, that is, a circular shape including this circular shape, and also includes a chord 2d connecting two points A and B in the circumferential direction of the circular shape.

  The point A is located above the vertical center C of the pusher 4, the point B is located below the vertical center C of the pusher 4, and the knob 2 is tilted to the center. When viewed from a direction inclined from the center, both the point A and the point B are straight lines extending in the left-right direction of the knob 2. Furthermore, the point A is arranged offset to the front side of the point B, and the chord 2d is pointed with respect to the bottom surface 4a on the front side of the pusher 4 when the knob 2 is not pressed. It inclines so that A is located in front of the point B.

  Note that the shape of the knob 2 on the back side only needs to satisfy the shape defined by the shape of the tilt viewed from the front side to the back side in FIG. 3, and in this embodiment, the center of tilting is satisfied. In the perspective view seen from the direction inclined from the circular shape, the circular shape 2c constitutes a cylindrical shape, and the string 2d constitutes the inclined surface AB. In this embodiment, the pusher 4 has a cylindrical shape or a rectangular parallelepiped shape, and the shape on the front side forms a flat bottom surface 4a.

  According to the composite operation type switch 1 of the present embodiment as described above, the following operational effects can be obtained. In particular, when the driver pushes or pushes the knob 2 so that the knob 2 is pushed from the left side to the right side in FIG. In contact with the bottom surface 4a on the front side of the pusher 4, at the initial stage of contact, a point that is inclined to be separated from the bottom surface 4a of the string 2d, that is, an end opposite to the point A B first contacts, and in the final contact stage, the entire string 2d can contact the bottom surface 4a on the front side of the pusher 4.

  Based on these things, it is possible to stabilize the tilting posture centering on the tilting direction of the knob 2, that is, the posture in the rotational direction not shown here. By these things, the rattle accompanying operation of the knob 2 can be prevented.

  Further, based on the geometrically inclined positional relationship between the string 2d formed on the back side of the knob 2 and the bottom surface 4a formed on the front side of the pusher 4 as in the present embodiment, the rattling of the knob 2 is reduced. For example, the guide length is long even when it is necessary to install the composite operation type switch 1 in the vicinity of the steering wheel that is easy for the driver to operate or in other places where there are many other restrictions. It is possible to solve problems such as non-removability, presence of design restrictions, inability to secure a means such as preload for applying a load in advance, and backlash due to the inability to apply grease.

  Further, in the present embodiment, when the surface operated by the driver on the front side of the knob 2 is toggled upward about the tilting center, that is, tilted in the up direction, the gap between the knob holder 3 and the knob 2 becomes the knob holder. The width is reduced by the contact surface of the knob 2 with respect to the knob 2 and the appearance can be improved, and tilting around the tilting direction of the knob 2 can be suppressed based on the contact action of the contact surface of the knob holder 3. Therefore, rattling can be prevented more effectively.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions are made to the above-described embodiments without departing from the scope of the present invention. be able to.
