Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever housing assembly structure for a shift lever for an automatic transmission of a vehicle which is shift-operated in a zigzag mode.

[0002]

2. Description of the Related Art In this type of shift lever housing assembly structure, the housing is conventionally fixed to the vehicle body, and a step-shaped detent groove hole is formed in the upper surface of the housing. The upper end of the shift lever is inserted through the detent slot toward the outside of the housing, and the shift lever is brought into contact with and engaged with the detent slot, and the shift lever is zigzag-moved according to the groove shape of the detent slot to perform a shift operation.

[0003]

By the way, in the above-described conventional structure for assembling the shift lever housing, the shift lever is brought into contact with and engaged with the step-shaped detent slot.
Since the zigzag movement is performed according to the groove shape and the shift operation is performed, the detent groove hole repeatedly receives the load from the shift lever each time the shift operation is performed.

Since the detent groove hole is formed integrally with the housing, the load received by the detent groove hole is
Therefore, the housing is required to have sufficient strength to withstand the load, particularly in terms of durability.

Further, in order for the shift lever to engage with the detent groove hole, it is necessary to manufacture and assemble the housing with high dimensional accuracy in order to obtain proper shift positions. Therefore, the manufacturing and assembling of the housing are troublesome, and the productivity and assembling are not good.

In view of the above facts, it is an object of the present invention to provide a shift lever housing assembling structure which does not require excessive strength in the housing and improves the productivity and the assembling property of the housing. .

[0007]

In order to solve the above problems, the present invention has a detent having a detent groove hole through which one end of a shift lever for an automatic transmission of a vehicle is inserted and abuttingly engaged. A base member for shifting the shift lever in a zigzag mode according to the shape of the slot, and the other end of the shift lever inserted from the inside to the outside on the outer surface attached to this base member and the shift operation of the shift lever. A housing assembling structure for a shift lever is provided, which is provided with a housing having an operation path display groove hole in which a path is displayed as an opening.

[0008]

According to the structure for assembling the shift lever housing according to the present invention, the shift operation path of the shift lever is visually recognized by the operation path display groove hole of the housing, and the other end portion of the shift lever is provided with the operation path display groove hole of the housing. By moving the shift lever in accordance with the groove shape of the detent groove hole, the shift lever is shifted in the zigzag mode.

Here, the detent groove hole is on the base member side, not on the housing side, and even if the shift lever is moved in zigzag each time the shift operation is performed, the base member receives the load applied to the detent groove hole. The load is not applied to the housing, and excessive strength is not required.

The operation path display groove hole on the outer surface of the housing is only required to allow the shift operation path of the shift lever to be visually recognized from the outside of the housing, and is required for the detent groove hole in manufacturing and assembling the housing. Such excessive dimensional accuracy is not required, manufacturing and assembling are facilitated, and housing productivity and assembling are improved.

Basically, the detent groove hole 16 is provided with a plurality of engaging portions 24 having different shapes corresponding to the range, and the shift lever 12 of the shift lever 12 is engaged with the engaging portions 24 so as to be contactable therewith. A pair of detent projections 26 is formed at the lower end on both sides in the vehicle lateral direction (FIGS. 2 and 3). When the shift lever 12 is moved in a zigzag manner in accordance with the shift operation, the detent protrusion 26 is moved from one engaging portion 24 to another engaging portion 24.

Further, the detent groove hole 16 is formed by communicating with a groove hole portion 28 on the side of the metal plate 18 made of metal and a groove hole portion 30 on the side of the resin plate 20 made of a synthetic resin which is opposed to the groove hole portion 28. The peripheral edge of the groove hole portion 30 on the 20 side slightly goes inward from the peripheral edge of the groove hole portion 28 on the metal plate 18 side (indicated by S in FIG. 2), and the groove hole portion 30 on the resin plate 20 side moves to the metal plate 18 side. The diameter is smaller than that of the groove portion 28 on the side.

A housing 32 made of synthetic resin is attached to the base member 14. The housing 32 is formed in the shape of a rectangular box whose lower part is open. Engagement holes 34 are formed on both side walls of the housing 32 in the vehicle lateral direction at both ends in the vehicle front-rear direction.

A rectangular hole 50 is formed in the central portion of the first cover 44 in the vehicle front-rear direction, and the second cover 46 and the third cover 48 face the rectangular hole 50 and obliquely intersect with the vehicle front-rear direction. Long holes 52 intersecting with each other are formed. The shift lever 12 is inserted through the intersection of the two long holes 52 (FIG. 5), and is inserted through the rectangular hole 50. Both side edges of each of the covers 44, 46, 48 in the vehicle lateral direction are engaged with a pair of guide grooves 54 formed on both sides of the vehicle lateral direction via the shift operation path 40 on the inner surface of the housing 32.
Each of the covers 44, 46 and 48 is individually slidable along the vehicle front-rear direction.

When the shift lever 12 is moved in the vehicle front-rear direction, the first, second and third covers 4 are interlocked with this movement.
All 4, 46 and 48 are moved in the vehicle front-rear direction. Further, when the shift lever 12 is moved in the lateral direction of the vehicle, the second cover 46 and the third cover 48 are interlocked with the shift lever 12 in the region of the rectangular hole 50 of the first cover 44 along the vehicle longitudinal direction. Are moved in mutually opposite directions and are moved relative to the first cover 44. That is, the intersecting portions (FIG. 5) of the long holes 52 of the second and third covers 46 and 48 are moved along the long holes 52, and the shift lever 12 is allowed to move in the lateral direction of the vehicle. At this time, the first cover 44
Is longer than the length of the operation path display groove 40 in the vehicle front-rear direction, and the second and third covers 4 are
The lengths of the vehicles 6 and 48 in the lateral direction of the vehicle are set to be longer than the length of the rectangular hole 50 of the first cover 44 in the vehicle front-rear direction.

A substrate 70 is provided inside the housing 32 on the outer side in the lateral direction of the vehicle. On the upper surface of the substrate 70, a plurality of LEs are provided on both sides in the lateral direction of the vehicle corresponding to the small holes 68.
D72 is arranged, the light emitted from the LED 72 passes through the small hole 68 to illuminate the current range indicator 66, and an optical path guide member 74 extending in the vehicle front-rear direction is provided in the vehicle lateral center portion. Light is emitted upward from the upper surface of the light guide member 74 by the lamp 76 arranged at the front end, and each range display character 64 is illuminated through the rectangular hole 58. According to the shift operation, only the current range indicator 66 corresponding to the current shift position of the shift lever 12 is illuminated.

The terminal block 84 and other lighting circuit components are disposed on the board 70. The board 70 is provided at both ends in the vehicle front-rear direction by using screws 80 to guide the optical path guide member 7.
It is fixed to the lower surface of the upper wall of the housing 32 via 4.

Further, in the figure, reference numeral 82 designates a rectangular hole formed in the base member 14, which is located opposite to the lower surface of the substrate 70.

Next, the operation of this embodiment will be described. Due to the operation path display slot 40 of the housing 32, the shift lever 12
The shift operation path is visually recognized, and the other end of the shift lever 12 is moved along the operation path display groove hole 40 of the housing 32, so that one end of the shift lever 12 is moved according to the groove shape of the detent groove hole 16. Shift lever 1
2 is operated in zigzag mode.

Here, the detent groove hole 16 abuttingly engaged with the shift lever 12 is not on the housing 32 side but on the base member 14 side, and the shift lever is provided in the operation path display groove hole 40 on the upper surface of the housing 32. Therefore, the base member 14 receives the load applied to the detent groove hole 16 even if the shift lever 12 is moved zigzag each time a shift operation is performed, so that the base member 14 receives the load.
No load is applied to No. 2, and excessive strength is not required.

That is, since the shift lever 12 is shifted according to the groove shape of the detent groove hole 16 on the housing 32 side, the operation path indicating groove hole 40 on the upper surface of the housing 32 does not need to contact the shift lever 12. Therefore, by forming the operation path display groove 40 in a shape that does not contact the shift lever 12, no load due to the shift operation is applied to the housing 32 side. Further, even if the operation path display groove hole 40 contacts the shift lever 12 to some extent, the load applied to the housing 32 as long as the shift lever 12 is shifted according to the groove shape of the detent groove hole 16 on the housing 32 side. Is
It is extremely small compared to the conventional one in which a detent slot is formed on the housing side.

The operation path display groove hole 40 on the upper surface of the housing 32 is only required to allow the shift operation path of the shift lever 12 to be visually recognized from the outside of the housing.
When manufacturing and assembling the housing 32, excessive dimensional accuracy required for the detent groove hole 16 is not required,
Manufacturing and assembling are easy, and the productivity of the housing 32 is
The assemblability is improved.

The base member 14 is the metal plate 1
8 and the resin plate 20, according to this, when the detent projection 26 is engaged with the engaging portion 24 in the detent slot 16, the metal portions are not directly contacted with each other, and the soundproof effect is obtained. In addition, the metal plate 18 reinforces the resin plate 20 and can sufficiently resist the load applied to the detent slot 16 (FIG. 2). Further, when the housing 32 is attached to the base member 14, resin-made members are attached between the engagement hole 34 of the housing 32 and the engagement protrusion 38 of the resin plate 20, which facilitates the attachment. There is. Of course,
The attachment of the housing 32 and the resin plate 20 is not limited to the snap fit between the engagement hole 34 and the engagement protrusion 38, and the material of the housing 32 is not limited to the synthetic resin. Also, the base member is the metal plate 18
However, the base member is not limited to the one obtained by outserting the resin plate 20.
It may be formed of a single plate made of metal or the like instead of being constituted by the resin plate 20 and the resin plate 20, and the effect of the present invention is not reduced by the difference in the material of the base member.

Further, since the portion where the shift lever 12 is engaged with the detent groove hole 16 is close to the rotational axes A and B of the shift lever 12, the detent projection 26 is projected on the shift lever 12, By engaging the detent projection 26 with the engaging portion 24 of the detent groove hole 16, the shift lever 12 and the detent groove hole 16 are reliably engaged, and therefore the shift operation is ensured. Of course, it is also possible to directly engage the peripheral surface of the shift lever 12 with the engaging portion 24 of the detent groove hole 16, and this does not prevent the effects of the present invention from being lost.
