The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment of the torsional spring of the utility model, as shown in Figure 3 and Figure 4, torsional spring include ontology 1 and are arranged in ontology
The affixed side arm of force 2 and force side force arm 3 at 1 both ends, force side force arm 3 include fixed section 31 and are movably connected on fixed section 31
Active segment 32.By on fixed section 31 increase active segment 32, by active segment activity adjustment exert a force side force arm 3 length,
The arm of force of torsional spring can be adjusted, and then achieve the purpose that adjust pedal force, the length that need to only adjust force side force arm 3 so just makes
Same torsional spring matches different pedal gears, keeps the design of torsional spring unified, to solve the design of torsional spring in the prior art and add
Work problem at high cost.
As shown in figure 4, the active segment 32 in the present embodiment is slidedly assemblied on fixed section 31, and active segment 32 is equipped with limit
Position hole 33, fixed section 31 are equipped with the limited block 34 being inserted into limit hole 33 when active segment 32 slides into setting position, need
When adjusting the length of force side force arm 3, active segment 32 is slid into the setting position of fixed section 31, then limited block 34 and limit
Active segment 32 is maintained at setting position by the limit cooperation of position hole 33, guarantees that force side force arm 3 is stablized in setting length.In addition, logical
It crosses limited block 34 and is inserted into limit hole 33 and active segment 32 is limited, it is not only easy to operate, and position limiting structure is simple.At it
In his embodiment, active segment and fixed section can be set as screw-nut structure, i.e., tool internal thread screw thread is equipped on active segment
Hole, the external screw thread of setting and screw-internal thread fit on fixed section, the adjusting of force side force arm lengths is realized by screwing active segment；Gu
Determining section and active segment can also be articulated and connected, and active segment and the hinged one end of fixed section are fixing end, and the other end is movable end, is needed
The movable end of active segment is turned to the direction close to fixed section when reducing force side force arm lengths and is bonded with fixed section, is needed
Movable end is around hingedly turning to active segment and fixed section center axially away from the direction of fixed section when increasing force side force arm lengths
Line is overlapped；Active segment and fixed section can also be that releasable connection structure passes through when needing to increased or decrease force side force arm lengths
Increase or disassembly active segment is realized；Limit hole can also be respectively provided on fixed section and active segment, when needs increase force side force brachium
Two limit holes are aligned and are fixed by fastener when active segment slides into setting position when spending.
Active segment 32 and fixed section 31 in the present embodiment are equipped with one section, and fixed section 33 is equipped with to be slided in active segment 32
When avoid the receiving portion of active segment 32 for holding limit block, such limited block 34 will not barrier activity section 32 slide.It is fixed
It is additionally provided in section 31 when active segment 32 slides into setting position for applying active force so that limited block 34 is convex to limited block 34
Receiving portion and the elastic component with the limit cooperation of limit hole 33 out, limited block 34 is when active segment 32 slides into setting position in elasticity
The lower protrusion receiving portion of part elastic force effect simultaneously limits cooperation with limit hole 33；Limited block 34 is equipped in limited block 34 and limit hole 33
With the stop section of 31 block of fixed section cooperation when limit cooperation, limited block can be prevented by stop section and the cooperation of 31 block of fixed section
34 are detached from from fixed section 31, guarantee the stability of limited block 34.Active segment 32 can be slided and be fixed back and forth in this way, keep torsional spring anti-
It is multiplexed in different pedal gears.In other embodiments, more than two active segments can be set as needed；Limited block can
It is securely fitted on fixed section, the sliding slot that accordingly passes through when being equipped on active segment in active segment sliding for limited block and in work
When dynamic section slides into setting position and limited block limits the limiting slot of cooperation along the glide direction of active segment, and sliding slot and limiting slot connect
Logical, rotating active segment when active segment slides into setting position makes limited block slide into the slot in limiting slot and with limiting slot by sliding slot
Wall limit cooperation, sliding slot and limiting slot can be L shape through slot；Can also on active segment fixing assembling limited block, set on fixed section
Set the sliding slot passed through when active segment sliding for limited block and when active segment slides into setting position and limited block is along active segment
The limiting slot of glide direction limit cooperation.For the structural strength for guaranteeing force side force arm 3, active segment 32 is tubular structure.At it
In his embodiment, active segment can also be to be stuck in rod-like structure on fixed section, have in rod-like structure and prolong along fixed section length direction
The gap stretched.
The switch of the umbrella strut similar with the cooperation of fixed section 31 of active segment 32, in the tune for carrying out force 3 length of side force arm
When section, limited block 34 in receiving portion, will not influence the sliding of active segment 32 under the side wall press effect of active segment 31；Activity
After 32 sliding in place of section, the limit hole 33 of active segment 32 is aligned with the limited block 34 of fixed section 31, and active segment 32 is no longer to fixation
Block applies pressure, and fixed block 34 protrudes receiving portion under the effect of elastic component elastic force and is inserted into limit hole 33 to active segment at this time
32 are limited, and guarantee that active segment 32 is in the setting position of fixed section 31.The length of force side force arm 3 is equal to fixed section at this time
31 with the overall length of active segment 32, compared with force side force arm is equal to the length of fixed section in the prior art, the length for the side force arm that exerts a force
Degree increases, and the pedal force of pedal gear reduces.When needing to increase pedal force, by pressing limited block 34, limited block 34 is released
Then limitation to active segment 32 pushes active segment 32 to slide into active segment 32 to fixed section 31 and is overlapped with fixed section 31, reduces
The length of force side force arm 3.Can also be not provided with receiving portion on fixed section, and be equipped with connecting hole corresponding with limit hole, into
When the fixation of row active segment and fixed section, limited block is inserted into the company that section and active segment are fixed in limit hole and connecting hole
It connects.
Use the torsional spring of the utility model as the return elastic component of pedal gear, the length of adjusting force side force arm can be passed through
Degree carries out the fast and effective fine tuning of pedal force, and does not have to renewal part repeatedly, constant according to torsional spring torque, increases the arm of force, reduces
The principle of power carries out structure optimization.
The specific embodiment of the pedal gear of the utility model, pedal gear include that pedal and being connected on pedal gear is used
Torsional spring structure phase described in specific embodiment of the torsional spring with above-mentioned torsional spring in the torsional spring for making pedal return, the present embodiment
Together, it repeats no more.
