The specific embodiment
In order to describe structure of the present utility model, Characteristic in detail, the following preferred embodiment of existing act also coordinates accompanying drawing to be described as follows.
First as shown in Figures 1 and 2, the bicycle speed-changing display device 10 that the utility model one preferred embodiment provides includes a pedestal 20, pedestal 20 includes a lower shell 30 and a upper casing part 40, one line wheel 50 mainly is set between lower shell 30 and upper casing part 40, the non-emphasis of the present utility model of other members between lower shell 30 and upper casing part 40, hold the applicant in this not narration in detail.Upper casing part 40 tops arrange a Transmission 60, a pointer 70, and a upper cover 80.
Line wheel 50 is driven by a shift cable (not shown) can when the user operates a speed change driving lever (not shown), and then rotates around an axle 90.In addition, line is taken turns 50 tops and is protruded out a fixed block 52, for Transmission 60, is fixedly arranged on fixed block 52, when rotating, line wheel 50 drives pointer 70 displacements by Transmission 60, therefore, the user watches the position of pointer 70 by a transparent block 82 of upper cover 80, can learn the gear of bicycle.The interaction relationship that focuses on pedestal 20, Transmission 60 and pointer 70 of the present utility model, details are as follows.
As shown in Figures 2 and 3, the upper casing part 40 of pedestal 20 has an end face 41, a bottom surface 42, run through end face 41 and bottom surface 42 an arc groove 43 and one with the crossing straight-line groove 44 of arc groove 43, and parallel with straight-line groove 44 an in fact and linear track 45 of a distance apart.Linear track 45 includes lower curtates 454 that are positioned at upper curtate 452, one 42 depressions from bottom surface of end face 41 tops, and a middle section 456 that connects upper curtate 452 and lower curtate 454, and the width of the width of upper curtate 452 and lower curtate 454 is greater than the width of middle section 456.
In details of the words, Transmission 60 can rotate between the position shown in the position shown in Fig. 4 and Fig. 5, makes pointer 70 straight-line displacement between the second place P2 shown in the primary importance P1 shown in Fig. 4 and Fig. 5 accordingly.In the form shown in Fig. 4, the guide pillar 76 of pointer 70 is positioned at a first end 624b of the arc guide barrel 324 of Transmission 60, when Transmission 60 rotates to the position shown in Fig. 6, pointer 70 moves to the one second end 624c that one the 3rd position P3 and its guide pillar 76 move to arc guide barrel 324, and Transmission 60 is while continuing to rotate to the position shown in Fig. 5,76 of the guide pillars of pointer 70 move towards the first end 624b of arc guide barrel 324 again in reverse direction.
In other words, bicycle speed-changing display device 10 provided by the utility model is than conventional construction, under the prerequisite of avoiding volume significantly to increase, the trip distance that utilizes arc guide barrel 624 to drive pointers 70 be by primary importance P1 and the 3rd position P3 apart from increasing again the distance of the 3rd position P3 to second place P2, therefore can adapt to the rotational angle range that line wheel 50 is larger, and then increase its displayable gear number, and do not need deliberately to increase the length of linear track 45 to maintain whole volume.
It is worth mentioning that, in the present embodiment, upper casing part 40 is interval between Transmission 60 and line wheel 50, therefore upper casing part 40 is provided with arc groove 43, be fixed in line wheel 50 same moving with line wheel 50 for Transmission 60 by arc groove 43, but the design of the shape of pedestal 20 is not emphasis of the present utility model and is not limited to the shape that the present embodiment provides, so pedestal 20 is not limited to be provided with arc groove 43.And, upper casing part 40 also can not be provided with straight-line groove 44, but the design that is provided with straight-line groove 44 can be positioned at straight-line groove 44 through arc guide barrel 624 for the guide pillar 76 of pointer 70 and, along straight-line groove 44 straight-line displacements, makes pointer 70 arrange more firmly and driven by Transmission 60.
In addition, in the present embodiment, the slide block 74 of pointer 70 and guide pillar 76 do not contact for the segment distance of being separated by, the design protruded out downwards from slide block than guide pillar in prior art, the pointer 70 of the present embodiment arranges to such an extent that comparatively firmly and more be difficult for beat, but the design that the utility model also can adopt slide block 74 and guide pillar 76 to join.
As shown in Figure 4, in the present embodiment, the indication section 724 of pointer 70 is arranged in holding rod installation portion 46 1 sides and points to a predetermined direction (at Fig. 4 for upper right side), and the installation section 722 of pointer 70 be self-indication section 724 first towards with predetermined party in the opposite direction (in Fig. 4, being lower left) extend again the direction bending towards holding rod installation portion 46.Thus, the curved design of pointer 70 can make in bicycle speed-changing display device 10 application more at gear and more easily allocate the position of each member and do not make overall volume increase.
The composed component that the utility model disclosed in the aforementioned embodiment finally, must be described again; it is only casehistory; not be used for limiting the scope of patent protection of this case, substituting or changing of other equivalence elements, also should be contained by the scope of patent protection of this case.
