Description

Motorcycle main switch lock internal mechanism

Technical field

The utility model relates to a kind of motorcycle main switch lock internal mechanism.

Background technology

At present, the multi-functional main switch lock of motor bike all is except steering lock (bolt) and starts the conductive plate group, have the function that many groups such as may command such as fuel tank cap lock, bench lock (or baggage compartment lock), hook look or main foot rest lock lockset opens and closes in addition, and the main switch lock all is locksets that other cables of interlock increase with control.Yet, lockset the more, the mechanism of interlock just the more, volume is just bigger, and the fitting surface of parts is also the more, except making accuracy requirement height, cost height, also is out of order than being easier in the use, the life-span is lower.

The motorcycle main switch lock of this type, though certain improvement and progress are arranged, but in the mechanism of its main interlock, still match with diecasting and be combined into the master, as shown in figure 10, its rotating cylinder 91, locating part 92, central siphon 93, transposase 19 4, snap rings 95 and interlock plate 96, it all is diecasting, especially rotating cylinder 91 and locating part 92, when making assembling, usually can't move, therefore must carry out edging and handle because of trickle burr cause blocking, and it is excessive as grinding to modify burr, can cause fault too.Same problem also occurs on central siphon 93, transposase 19 4, snap rings 95 and the interlock plate 96.

In addition, the above-mentioned structure of commonly using also exists overall volume too big, the main switch lock can't be arranged at the shortcoming of fuel tank top; In addition, the crank element 97 of this lockset is being done multistage when operation, even be not pressed down that there is misoperation in regular meeting yet with the disappearance of making double-action plate 98 and locking bar 99.These 2 disappearances perhaps are not present in the early stage product, but, early stage product does not drive the lockset of so many groups, therefore, under the preceding topic that will drive many group locksets, reduce parts, reduced volume, shorten actuating length and avoid misoperation, all be the problem that to consider in fact, and be not that simple improvement part assembly can be reached.

Crank rod is one shaft-like, and its upper end build-in is in the core lower end, and the stage casing extends laterally first drive block, side direction bends out second drive block and baffle ring, and its lower end is a start end, and crank rod hypomere socket one spring also is placed through in the conductive plate group;

Locking bar is arranged in the transverse holes of lock, and its inner is provided with a capel and rabbets a double-action plate, it is corresponding with capel chimeric that double-action plate is provided with caulking groove, double-action plate central authorities are provided with the slotted eye that inner edge is a cam-like, and second drive block of crank rod places this slotted eye and the interlock double-action plate, and double-action plate bends one folding piece in addition;

The conductive plate group is fixed on the lock with bolt;

First pulling piece, second pulling piece and the 3rd pulling piece are arranged at the side of lock respectively, and are respectively equipped with one folding piece; The tabs of first pulling piece is by the projection butt interlock of first moving part, and the tabs of second pulling piece is the forked projection of pitching second moving part, and by this projection interlock back and forth, the tabs of the 3rd pulling piece is interlock by the tabs butt of locking bar; In addition, interlock glove case lid, fuel lid, hook are locked respectively for first pulling piece, second pulling piece and the 3rd pulling piece;

During assembling, first moving part places lock inside, core is arranged in the clearance hole of the clearance hole of lock and first moving part, and ride over during the lug normality of core on the arc wall of first moving part, in lock in-to-in chute, the tabs of first pulling piece is by the projection butt interlock of first moving part with the corresponding embedding cunning of the embedding wing for the banking stop of first moving part; In addition, corresponding one of two grooves that embed of the embedding wing of banking stop, an end of its spring of butt under the banking stop, this spring other end is against in the hole, rank of second moving part, the caulking groove of second moving part is embedded the end pin of torque spring, the other end pin of torque spring is stretched in the elongated slot that places positioning plate, and bolt penetrates fixed orifice positioning plate is fixed in the lock, and the tabs fork of second pulling piece is lived the projection of second moving part; Again, the crank rod epimere penetrates the clearance hole of positioning plate, the clearance hole of the clearance hole of second moving part and first moving part, the upper end build-in of crank rod is in the embedding hole of core lower end, locking bar is arranged in the transverse holes of lock, its capel is embedded in the caulking groove of double-action plate, double-action plate is taken on the terrace edge of lock inwall, and the slotted eye of double-action plate central authorities places and interlock for second drive block of crank rod, the tabs of the tabs butt of double-action plate and interlock the 3rd pulling piece, its spring of crank rod hypomere socket, and prop up this spring one end with baffle ring, this spring other end is against on the conductive plate group, it is interior to start conductive plate that the start end of crank rod lower end is placed through the conductive plate group, and the conductive plate group is fixed on the lock with bolt.

After adopting such scheme, the utlity model has following advantage:

1, the defective products on minimizing is made.First moving part 3 changes into banking stop 36 and cooperating, because banking stop 36 is to wait the thick sheet metal punch forming, as long as groove 34,35 is a bit larger tham the thickness of banking stop 36, first moving part 3 cooperates without a doubt with banking stop 36.As for, the lug 12 of core 1 at clearance hole 31 inwalls of first moving part 3 slippage no problem more up and down, as long as the breach of arc wall 311 than the width of lug 12 bigger.Original because of two matable assemblies all with die cast, and then cause trickle burr, make the assembly fitting surface unsmooth or wipe card and the disappearance of formation defective products will no longer exist.In like manner, second moving part 4 also has same advantage with its positioning plate 44.

2, the assembly efficiency of movement is good.First drive block, 51 direct interlock second moving parts 4 of core 1 interlock crank rod 5, make the stroke of its interlock second pulling piece 82 actions still less and more direct, and resetting of second pulling piece 82 can its forked tabs 821, and directly second moving part 4 is resetted by torque spring 43 and interlock certain.

3, reduce the setting of parts.Second moving part 4 drives the assembly of second pulling piece 82 because be direct interlock and more simplifying, and further saves the retracing spring of second pulling piece 82.

4, reduce manufacturing cost.Because the diel and the manufacturing cost of banking stop 36 are more saved more than the mould and the manufacturing cost of diecasting, to add, the assembly that second moving part 4 drives second pulling piece 82 is more simplified, and then overall cost more descends.

5, avoid opening by mistake locking bar 6.Second drive block 52 of crank rod 5 only presses down Shi Caihui at core 1 and stretches in the slotted eye 622 of double-action plate 62, so do not have the situation of misoperation in operation.

In sum, the utility model not only manufacturing cost reduces, and in the operation of each pulling piece of interlock (as 81,82,83), stroke reduces and makes action more certain, core 1 also reduces the setting of a lot of parts, the more important thing is, when will press down, crank rod 5 just can drive double-action plate 62 and then drive unblanking or locking of locking bar 6, and it is more perfect so to consider planning.
