Detailed description of the invention
Below, with reference to accompanying drawing, embodiment of the present utility model is described.As an application examples, present embodiment the utility model is applied to the example on the gear shift device T of the floor type gear changing mode arranged on automobile (not shown) indoor floor F.Fig. 1 is the birds-eye view of the gear shift device T arrived seen from above, and Fig. 2 is the lateral plan of gear shift device T.As shown in Figures 1 and 2, in present embodiment, gear-shift lever 2 extends upward from the shell 1 be integrally formed with floor console C.
In addition, although the diagram of eliminating, before and after the shell 1 of gear shift device T, be such as provided with the change-over switch, glass stand or other storage members that control speed change, shell 1 there is no the leeway of lengthening at fore-and-aft direction.Therefore, as shown in Figure 2, the shell 1 upwards swelled from floor console C mesa-shaped ground is configured to, and the surperficial from it 1a of its front surface 1b tilts to extend downwards.Thus, meanders is formed with at front surface 1b and upper surface 1a boundary part.
In the upper end of gear-shift lever 2, the shifting handle 3 for driver's hand-held operation is installed.As shown in Figure 1, gear shift groove 4 is run through in the root side of gear-shift lever 2, and this gear shift groove 4 can guide in the movement of shift lever 2.On the gear shift frid 5 that the surperficial 1a that gear shift groove 4 is formed on shell 1 is arranged.In the present embodiment, gear shift groove 4 is configured to the groove portion extended along vehicle commander direction and the consecutive meander-like in groove portion (i.e. stepped appearance gear shift groove) extended along overall width direction.
In gear shift groove 4, position is foremost set to parking gear, is disposed with backing car gear, neutral position and advance gear etc. backward from this parking gear.Driver can along gear shift groove 4 forwards, backwards or left and right operation gear-shift lever 2, by making the front position shown in gear-shift lever 2 long and two-short dash line in fig. 2 and moving between rearmost position (not shown), the selection of any one gear (speed range) can be realized.
In addition, as shown in Figure 3, shell 1 possesses, and is arranged on the outer enclosure 10 on gear shift frid 5 and arranges thereunder for holding the inner shell 11 of gear-change operation mechanism.In the below (back side) of gear shift frid 5, arrange and promisingly prevent rubbish etc. from entering and the resin-made slide cover 6 gear shift groove 4 closed.As shown in Figure 4, slide cover 6 is rectangular resin sheet, and about midway location of its length direction is processed with the groove 6a that broad ways (Y-direction) extends, and this groove 6a is for the root break-through of gear-shift lever 2.
Thus, when operating gear-shift lever 2 along gear shift groove about 4, gear-shift lever 2 only moves in groove 6a, and slide cover 6 can not be made to move left and right.On the other hand, when before and after gear shift groove 4, (X-direction) operates gear-shift lever 2, gear-shift lever 2 can push the leading edge of groove 6a or trailing edge and slide cover 6 is slided forward or backward.
Near the end of the both sides of the Width of slide cover 6, the direction of slip (X-direction) respectively along this slide cover 6 is provided with multiple protuberance 7 dispersedly.Each protuberance 7 from lower surface (back side) projection downwards of this slide cover 6, and is processed as one with slide cover 6.In addition, the cross sectional shape of each protuberance 7 is semicircle, and extends certain length to the Width (Y-direction) of slide cover 6.In addition, will be described later about the height (projection amount) of protuberance 7 from slide cover 6 lower surface projection.
The below of slide cover 6 is provided with inner shell 11.In inner shell 11, be provided with the elongated open portion 11a for gear-shift lever 2 movement.In addition, the upper surface of inner shell 11 is provided with two slip slide rails 12.These two slip slide rails 12 extend along the direction of slip (X-direction) of slide cover 6.Further, as shown in Figure 5, each slip slide rail 12 slidably mates with the multiple protuberances 7 on above-mentioned slide cover 6 respectively.Thus, slide cover 6 can forwards or rear (length direction: X-direction) slide, the movement of Width (Y-direction) is then restricted.
At this, as shown in Figure 2, because the shape of shell 1 is processed to, the surperficial from it 1a of its front surface 1b tilts to extend downwards, meanders is formed at front surface 1b and upper surface 1a boundary part, so, as shown in the long and two-short dash line in Fig. 2, when gear-shift lever 2 is moved to forefront, the front part 6b thereupon the slide cover 6 forwards slided can the flexural deformation corresponding to the shape of the meanders of shell 1.Therefore, larger sliding resistance can be subject to when slide cover 6 slides into the front end of shell 1.And when the sliding resistance of slide cover 6 increases, noise during operation gear-shift lever 2 can become large, and slide cover end is also easily frayed.
Consider this factor, in the present embodiment, as shown in Figure 6, the rising height (projection amount from the lower surface projection of slide cover 6) of multiple protuberance 7 is set to, (namely the centre of the protuberance row formed from the multiple protuberances arranged along direction of slip (X-direction) successively decreases to the front end that this protuberance arranges successively, from middle part, the closer to front end, projection amount is less).
Adopt such structure; even if when protuberance (guide block) 7 being set to end (leading section) of slide cover 6 in the intensity for guaranteeing slide cover 6 leading section, the flexural deformation of the leading section of slide cover 6 still can not be affected always.Therefore, when operating gear-shift lever 2, even if the front part 6b of slide cover 6 is corresponding to the shape significantly flexural deformation of the meanders of shell 1, the sliding resistance suffered by the front part 6b of this slide cover 6 also can not become large.Thus, while the operating characteristic improving gear-shift lever 2, action noise during operation gear-shift lever 2 can be reduced.In addition, the wearing and tearing of slide cover 6 end can also be reduced, extend the service life of slide cover 6.
On the other hand, as shown in Fig. 4 and Fig. 6, in the present embodiment, the interval of the multiple protuberances 7 arranged along direction of slip (X-direction) is set to, (namely the centre of the protuberance row formed from the multiple protuberances arranged along direction of slip (X-direction) increases progressively to the front end that this protuberance arranges successively, from the middle part of slide cover 6, the closer to the front end of slide cover 6, interval is wider).Adopt this structure, effectively can reduce the sliding resistance suffered by front end of slide cover 6 further.
In addition, the utility model is not limited by the structure of above-mentioned embodiment, also can comprise other all embodiment.
Such as, in the above-described embodiment, although have employed the structure making the interval between multiple protuberance 7 increase progressively successively while making the rising height of multiple protuberance 7 successively decrease successively, the utility model is not limited to this, also can adopt the structure only making the rising height of multiple protuberance 7 successively decrease successively.
In addition, in the above-described embodiment, although the cross sectional shape being arranged on the protuberance 7 on slide cover 6 is for semicircle, the utility model is not limited to this, and the cross sectional shape being arranged on the protuberance 7 on slide cover 6 such as also can be triangle, other shapes such as trapezoidal.
In addition, in the above-described embodiment, the front part 6b that illustrate only slide cover 6 is easy to diastrophic structure corresponding to the shape of the sweep of the shell 1 of gear shift device T, but the utility model is not limited to this.Also for making the rearward end of slide cover 6 easily deformable, and the rising height of multiple protuberances 7 of arrangement on slide cover 6 can be set as, successively decrease successively to rear end from centre.In addition, also the rising height of multiple protuberances 7 of arrangement on slide cover 6 can be set as, while successively decreasing successively to front end from centre, also successively decrease successively to rear end from centre.Meanwhile, also the interval between multiple protuberances 7 of arrangement on slide cover 6 can be set as, increase progressively successively to rear end from centre, or, while increasing progressively successively from centre to front end, also increase progressively successively from centre to rear end.
In addition, be suitable for gear shift device of the present utility model and be not limited to floor type gear changing mode, the utility model is such as also applicable to the gear shift device of steering column gear changing mode etc.
