Description

  The present invention relates to a vehicle speed change operation device that is disposed on an instrument panel of a vehicle and is capable of speed change operation.

  In general, a vehicle shift operation device for a vehicle equipped with an automatic transmission includes a shift lever (select lever) that can swing in the front-rear direction, and the shift operation of the vehicle can be performed by operating the shift lever. It is said that. However, in recent vehicles, from the viewpoint of effective use of the floor area and improvement in operability, an instrument panel provided with a vehicle speed change operation device has become widespread.

  In the vehicular speed change operation device provided on such an instrument panel, since the shift lever protrudes on the seat side, when an impact load is applied to the shift lever, it is extremely necessary to absorb the impact. It has become. Therefore, conventionally, for example, a device that breaks a connecting portion (bracket) between a vehicle transmission operation device main body that holds a shift lever and a vehicle body and absorbs an impact load applied to the shift lever due to the break has been proposed. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, in the above-described conventional vehicle speed change operation device, the shock absorbing means destroys the connecting portion (bracket) with the vehicle body, so that the instantaneous shock is broken and continuous shock absorption is difficult. There was a problem. Moreover, since it is necessary to provide a separate new means such as insert molding on the bracket, for example, there is a problem that the manufacturing cost increases.

  The present invention has been made in view of such circumstances, and it is possible to achieve sufficient shock absorption by causing continuous destruction and to suppress an increase in manufacturing cost due to the provision of shock absorbing means. An object of the present invention is to provide a vehicular speed change operation device that can do this.

  The invention according to claim 1 is made of a resin molded product, and is attached to a shift operation device main body attached to an instrument panel of the vehicle, and is swingably attached to the shift operation device via a shaft pin. For a vehicle comprising: a shift lever for performing a gear shifting operation; and an impact absorbing means for absorbing the shock load by breaking the gear shifting device body when a predetermined impact load is applied to the shift lever. In the speed change operation device, the impact absorbing means is formed over a direction in which the shaft pin moves when the impact load is applied from a portion of the speed change operation device main body that supports the shaft pin. A plurality of ribs extending in the orthogonal direction are formed in a ladder shape.

  According to a second aspect of the present invention, in the vehicular speed change operating device according to the first aspect, the impact absorbing means includes the impact between the portion supporting the shaft pin and the plurality of ladder-shaped ribs. An initial load absorbing rib extending in a direction in which the shaft pin moves when a load is applied is formed.

  According to a third aspect of the present invention, in the vehicular speed change operating device according to the first or second aspect, the shaft pin comprises a stepped pin having a stepped portion on one end side, and the one end is connected to the speed change operating device. While being inserted into the insertion hole formed in the main body and being locked at the stepped portion, the other end is made to come into contact with a retaining member formed on the transmission operation device main body to prevent the retaining. .

  According to the first aspect of the present invention, since the shock absorbing means is configured such that the shaft pin breaks the plurality of ribs arranged in a ladder shape, sufficient shock absorption is achieved by causing continuous breakage. In addition, the shaft pin that supports the shift lever can be used, and a plurality of ribs are built into the speed change operation device body made of a resin molded product, so that an increase in manufacturing cost due to the shock absorbing means is suppressed. be able to.

  According to the invention of claim 2, the impact absorbing means is initially extended in a direction in which the shaft pin moves when an impact load is applied between a portion supporting the shaft pin and a plurality of ladder-shaped ribs. Since the load absorbing ribs are formed, it is possible to cause continuous destruction while effectively absorbing the initial impact load, and to achieve more sufficient shock absorption.

  According to the invention of claim 3, since one end of the shaft pin is locked at the stepped portion and the other end is prevented from coming off by the contact of the retaining member, it is easy to assemble the shaft pin. In addition, when an impact load is applied and the shaft pin slides while destroying the impact absorbing means, smooth sliding is possible and the impact load can be absorbed more reliably.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
A vehicle speed change operation device according to this embodiment is attached to an instrument panel of a vehicle to perform a speed change operation. As shown in FIGS. 1 to 3, a speed change operation device main body 1 and a shift lever are provided. 2, the shaft pin 6, and the impact absorbing means 9. When an impact load greater than a set value is applied to the shift lever 2, the impact absorbing means 9 is destroyed by the shaft pin 6, It is configured to absorb the load.

  The speed change operation device main body 1 is made of a resin molded product molded into a predetermined shape, and is attached to an instrument panel of a vehicle via a plurality of brackets 1a integrally formed at a predetermined position. A shift lever 2 is swingably held in the transmission operation device body 1 and a decorative panel 4 is disposed on the upper portion thereof. The decorative panel 4 is formed with a linear notch 4a. Yes.

  A shift lever 2 protrudes from a cutout 4a of the decorative panel 4, and a shift knob 3 that is gripped by the driver is formed at the tip thereof. The shift lever 2 is swingably attached via a shaft pin 6 formed at a predetermined position of the speed change operation device main body 1 and swings in accordance with the operation of the shift knob 3 by the driver so that a desired speed change is achieved. It is for operation. Further, on the base end side of the shift lever 2, there is formed a locking portion 2a for locking one end of a wire (not shown) connected to the transmission of the vehicle.

  With the above configuration, when the driver operates the shift knob 3 to swing the shift lever 2 around the shaft pin 6, the transmission is operated via the wire to shift the vehicle. . Note that an operation button 3a is formed on the shift knob 3, and a predetermined operation (for example, an operation from the P range to the R range) can be performed by pressing the operation button 3a. That is, by pressing the operation button 3a, the operating member 7 is lowered, and the operation pin 5 locked to the window portion 1b formed in the transmission operation device body 1 is lowered, thereby releasing the lock and shifting. A predetermined swing operation by the lever 2 is enabled.

  The shaft pin 6 is for swingably supporting the shift lever 2 as described above. As shown in FIG. 3, the shaft pin 6 is a stepped pin having a step portion 6a on one end (right end in the figure). Become. The shaft pin 6 is locked at the step portion 6a while one end is inserted into the insertion hole 1c formed in the transmission operation device main body 1, and the contact plate 8 (disengagement) is connected to the other end (the left end in the figure). The stopper member is brought into contact with the stopper member to prevent the stopper member from coming off. The contact plate 8 is made of a metal plate material fixed to the side surface of the transmission operation device main body 1 and is in a state where one surface is in contact with the other end of the shaft pin 6 (or a state close enough to prevent the shaft pin 6 from coming off). Is formed.

  Accordingly, when the shaft pin 6 is assembled to the transmission operating device main body 1, it is sufficient to insert the shaft pin 6 from one end into the insertion hole 1c and prevent the other end from being removed by the contact plate 8, so that the assembly operation of the shaft pin is facilitated. can do. Further, since no fastening means or the like is formed at both ends of the shaft pin 6 as compared with the case where the nut pin or the like is used to prevent the removal, for example, the impact force is applied and the shaft pin 6 destroys the impact absorbing means 9. When sliding, smooth sliding without being caught is possible, and the impact load can be absorbed more reliably.

  Here, in the vehicle speed change operation device according to the present embodiment, the impact absorbing means 9 is formed on both side surfaces of the speed change operation device body 1 (near the position where the shaft pin 8 is disposed). As shown in FIGS. 4 and 5, the impact absorbing means 9 is configured such that when an impact load is applied from a portion 10 that supports the shaft pin 6 (an annular portion formed on the periphery of the insertion hole 1 c), It is formed over the direction in which the pin 6 moves (downward in the figure).

  More specifically, the shock absorbing means 9 includes a portion in which a plurality of ribs 12 extending in a direction substantially orthogonal to the direction in which the moving pin 6 moves are formed in a ladder shape, and a portion that supports the rib 12 and the shaft pin 6. 10 and two initial load absorbing ribs 11 formed between them. The initial load absorbing rib 11 is formed so as to extend in a direction in which the shaft pin 6 moves when an impact load is applied, and is formed integrally with the transmission operating device main body 1 like the plurality of ribs 12. . In addition, thick guide portions 13 are extended on both sides of the impact absorbing means 9 so as to guide the shaft pin 6 when it moves.

  When an impact load is applied to the shift lever 2 (specifically, the shift knob 3), the shaft pin 6 that supports the shift lever 2 breaks the initial load absorbing rib 11 together with the portion 10 that supports the shaft pin 6. Then, it moves along the guide portion 13 while sequentially breaking the ribs 12. Since the initial load absorbing rib 11 extends in the moving direction of the shaft pin 6, the breaking load is larger than that of each rib 12, and a relatively large initial impact load can be effectively absorbed, and the subsequent impact load. (Secondary impact load) can be continuously absorbed by sequential destruction of the plurality of ribs 12.

  That is, since the impact absorbing means 9 is configured such that the shaft pin 6 breaks the plurality of ribs 12 arranged in a ladder shape, sufficient shock absorption can be achieved by causing continuous breakage, Since the initial impact load can be absorbed by the initial load absorbing rib 11, more sufficient impact absorption can be achieved. Further, the shaft pin 6 that supports the shift lever 2 is diverted, and the plurality of ribs 12 and the initial load absorbing rib 11 are integrally built in the speed change operation device main body 1 made of a resin molded product. By providing the shock absorbing means, it is possible to suppress an increase in manufacturing cost of the vehicle speed change operation device.

  However, the dimensions (thickness direction and width direction) of the initial load absorbing rib 11 and each rib 12 should be determined according to the set load. Can be optimized. The number of ribs 11 for absorbing the impact load is not limited to two, but may be one having a dimension adjusted according to a set load, for example, as shown in FIG. In addition, it is preferable that the number of the ribs 12 formed in a ladder shape is set according to an assumed secondary impact load.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, as shown in FIG. 7, instead of the initial load absorbing rib 11, it is integrated with a portion 10 that supports the shaft pin 6. The formed thick portion 11 ′ may be formed, and the thick impact portion 11 ′ may be absorbed by the shaft pin 6 when the shaft pin 6 is broken. Further, as shown in FIG. 8, the impact absorbing means 9 may be formed by an integral rib 12 'with the guide portion and each rib being flush with each other.

  A plurality of ribs formed in a ladder shape are formed over a direction in which the shaft pin moves when an impact load is applied from a portion supporting the shaft pin in the transmission operation device body, and extending in a direction substantially orthogonal to the direction. As long as the vehicle speed change operation device is provided with the shock absorbing means, it can be applied to devices having different appearances or other functions.
