[Industrial applications]

 The present invention relates to a change lever for an automobile, which prevents deformation of a lock bracket due to erroneous operation during shift lock in a change lever of an automatic transmission.

[0002]

[Prior art]

 In recent automobiles, various automatic transmissions have been adopted in order to reduce the driving operation while driving. For example, the operation of a change lever controls the supply of hydraulic pressure to automatically change the transmission gears. What you have done is known. In such an automatic transmission, the push button of the knob is pushed in, the guide pin is slid downward through the push rod, the guide pin is released from the lock of the guide plate, and the change lever can be swung. A change lever structure that can be operated is adopted, but in such a structure, when switching from the parking range P to the driving range, for example, the drive range D, if the accelerator pedal is mistakenly depressed with the brake pedal, runaway will occur. Is concerned. Therefore, the conventional vehicle change lever is provided with a lock plate below the guide pin to limit downward sliding of the lock pin at the parking position, and when the brake pedal is depressed, the lock plate is swung to swing the guide pin. Some have made it possible to slide down and switch to the driving range.

[0003]

[Problems to be solved by the device]

 However, in the conventional vehicle change lever described above, if the push button of the knob is erroneously pressed hard in the shift lock state where the downward sliding of the guide pin is restricted, the guide pin will hit the lock plate strongly and a large load will be placed on the lock plate. There is a problem that the lock plate is deformed due to the heavy weight. In particular, if the driver is not accustomed to the operation, he or she may judge that the push button pushing force is insufficient to unlock the change lever and tend to push the push button forcefully. Was a concern. Therefore, in order to prevent the lock plate from being deformed due to an erroneous operation, it was necessary to manufacture the lock plate from a thick iron plate. In view of the above problems, it is an object of the present invention to provide a change lever for an automobile that prevents the lock plate from being deformed due to an erroneous operation.

[0004]

[Means for Solving the Problems]

 In view of this, the change lever for an automobile according to the present invention has the following features: "By pushing the push button, the guide pin slides downward to release the lock with the guide plate, while the lower slide of the guide pin in the parking position can swing. In a changer lever for an automobile, which is configured to be restricted by a lock plate, a push button is formed by connecting a push-in portion and an operating portion so that they can be bent and bent so that the inclined surfaces extending outward are opposed to each other. A spring member that is elastically deformed by a predetermined load is interposed between the pushing portion and the operating portion to limit bending, and the spring portion material is pushed by a pushing load equal to or more than a predetermined value of the push button in the shift lock state. Is elastically deformed so that the operating part is bent with respect to the push-in part. "

[0005]

[Action]

 When the pushbutton operation part is pushed in while the shift lock is released, a load below the specified value is applied to the spring member, so the spring member does not deform and bending of the operation part is restricted. The push button is pushed in as it is, the push rod slides downward, and the guide pin is pushed down. On the other hand, if the push button is accidentally pushed hard in the shift lock state, the guide pin is restricted from sliding downward by the lock plate, so a load of a certain value or more acts on the spring member of the push button. The spring member elastically deforms, the operating part bends against the push-in part, and the push-in load is absorbed by the push button.The push-in part is not pushed in.Therefore, the push rod does not slide downward, so the lock plate Excessive load does not work.

【Example】

 Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 3 show a vehicle change lever according to an embodiment of the present invention. In the change lever 1 for a vehicle, the change lever 2 is formed by using a pipe, and the lower end of the change lever 2 is provided with a mounting shaft 20 so that the change lever 2 can swing on the mounting body B in the longitudinal direction. A knob 22 is attached to the upper end of the change lever 2. Further, a slide groove 21 is formed in the lower part of the change lever 2 in the axial direction, and a guide pin 4 is slidably inserted into the slide groove 21 with its tip protruding so that the guide pin 4 is provided below the guide pin 4. The spring member 8 for urging the guide pin 4 upward is compressed. On the other hand, a guide plate 5 is fixed to the side of the change lever 2 by a bolt on the device body B, and a guide groove 50 for guiding and locking the guide pin 4 when the change lever 2 is operated is formed in the guide plate 5. ing. A lock plate 6 is rotatably attached to the attachment shaft 20 of the change lever 2, and the lock plate 6 is located below the guide pin 4 in the parking position to restrict downward slide of the guide pin 4 ( As shown in FIG. 1 (b)), when the brake pedal is depressed, the guide pin 4 is rocked forward to unlock the guide pin 4 (see arrow A in FIG. 1 (b)). A push rod 7 is provided inside the change lever 2, a cam portion 70 is formed at an upper end portion of the push rod 7, and a lower end of the push rod 7 is connected to a guide pin 4.

A push button 3 is attached to the side surface of the knob 22 so as to be retractable. The push button 3 is configured by swingably connecting an operating portion 31 and a pushing portion 32 with a hinge 33, and the pushing portion 32 is formed with an operating cam portion 30 that cooperates with a cam portion 70 of the push rod 7. Has been done. The facing surfaces 31a and 32a of the operating portion 31 and the pushing portion 32 have a substantially V-shape that spreads outwardly from each other, and a leaf spring 35 is elastically deformed between the facing surfaces 31a and 32a under a predetermined load. And a stopper 34 protruding from the outside of the hinge portion 33 of the operating portion 31, and the stopper 34 abuts the outer end surface of the pushing portion 32 so that the operating portion 31 is straight to the pushing portion 32. It is supposed to be retained.

Next, the function and effect will be described. When the shift range is changed from the parking P to the traveling range, for example, to the drive D, when the brake pedal is depressed, the lock plate 6 is swung forward (see arrow A in FIG. 1 (b)) and the shift lock is released. In this state, when the push button 3 is pushed in, a load of a predetermined value or less acts on the plate spring 35 of the push button 3, so that the leaf spring 35 is not deformed, and the operating portion 31 is pressed against the pushing portion 32. Hold straight. Therefore, as shown in FIG. 3 (a), the pushing portion 32 of the push button 3 is pushed into the knob 22 as it is, the push rod 7 slides downward, and the guide pin 4 is pushed downward, whereby the guide plate 4 is pushed down. The lock with 5 is released and the change lever 2 can be operated. On the other hand, in the shift lock state, if the push button 3 is erroneously pressed strongly, the guide pin 4 is restricted from sliding downward by the lock plate 6, so that the leaf spring 35 of the push button 3 is loaded with a load of a predetermined value or more. Will work. Then, as shown in FIG. 3 (b), the leaf spring 35 elastically deforms and the operating portion 31 bends with respect to the pushing portion 32, and the pushing load is absorbed by the elastic deformation of the leaf spring 35, and the pushing portion 32 is not pushed into the knob 22, the push rod 7 does not slide downward, and an excessive load does not act on the lock plate 6. Further, as a result of the operation portion 31 being bent obliquely as described above, it becomes difficult to apply an excessively large pushing force to the push button 3, which also prevents the action of an excessive pushing load on the lock plate 6. . As a result, the lock plate 6 is prevented from being deformed and its durability can be secured, and since a large load does not act on the lock plate 6, it becomes possible to manufacture an inexpensive lock plate 6 from a thin iron plate or synthetic resin. .
