The magnetoresistive cell 20 is swingably set on the bracket 41 and is located at outside the magnetism runner 13, the magnetoresistive cell 20 packet Containing an adjusting seat 21 and multiple magnetic elements 22, one end of the adjusting seat 21 is swingably set on the bracket 41, and the adjustment An inner space 23 is formed in seat 21, which can provide the magnetism runner 13 and protrude into, the 22 groups of installings of each magnetic element In in the adjusting seat 21 and be located at the inner space 23 in, wherein the adjusting seat 21 include two sheet bodies 24 and a connecting plate 25, two Sheet body 24 is oppositely arranged and is swingably set on the bracket 41, which is located at two sheet bodies 24.
Windage unit 30a is removably set to the lateral surface of the magnetism runner 13, wherein as shown in Figures 1 and 2, The windage unit 30a includes a turbine 31a, and turbine 31a is set to the side of the magnetism runner 13 and includes a wheel body 32a, more An a windage wing 33a and pressuring plate 34a, wheel body 32a are locked on the side of the magnetism runner 13, and each windage wing 33a is annular in shape It being set on wheel body 32a with being alternatively arranged, pressuring plate 34a is set on each windage wing 33a and relative to wheel body 32a, in addition, As described in Figure 3, the second preferred embodiment of windage of the present invention and reluctance type resistance adjustment device, the windage unit 30b packet are disclosed The two sides of the magnetism runner 13 are set to containing two turbine 31b, two turbine 31b, each turbine 31b includes a wheel body 32b, multiple windages A wing 33b and pressuring plate 34b, wheel body 32b are locked on the magnetism runner 13, and each windage wing 33b is set with being annularly alternatively arranged In on wheel body 32b, pressuring plate 34b is set on each windage wing 33b and relative to wheel body 32b.
Among the above, as shown in Figures 4 and 5, it discloses windage of the present invention and the third of reluctance type resistance adjustment device is preferably real Example is applied, which includes a fan 35c, and fan 35c is locked on the side of the magnetism runner 13 and includes multiple wind Wing 36c is hindered, each windage wing 36c is locked on the magnetism runner 13 with being annularly alternatively arranged, in addition, as described in Figure 6, disclosing this 4th preferred embodiment of invention windage and reluctance type resistance adjustment device, the windage unit 30d include two fan 35d, two wind The two sides that 35d is set to the magnetism runner 13 are fanned, each fan 35d includes multiple windage wing 36d, between each windage wing 36d is annular in shape Every being locked on the magnetism runner 13 in a row.
As shown in Fig. 2, Fig. 7 and Fig. 8, the first preferred embodiment of windage of the present invention and reluctance type resistance adjustment device is disclosed Installation form, windage of the present invention and reluctance type resistance adjustment device setting the bracket 41 be an exercycle 40 bracket 41, The exercycle 40 includes also to step on wheel 42, one comprising one outside the bracket 41 to adjust bar 43 and a connection piece 44, this steps on that wheel 42 is set to should On bracket 41, which is movably disposed on the bracket 41 and connects the connecting plate 25 of the adjusting seat 21, the connector 44 are set to the assembly block 12 for stepping on wheel 42 and connecting windage of the present invention and reluctance type resistance adjustment device, and user can pass through The adjustment bar 43 controls the connecting plate 25 close to or far from the magnetism runner 13 is opened, and adjusts each magnetic element 22 and turns with the magnetism The distance of wheel 13 to adjust the resistance of the magnetoresistive cell 20 offer, and then adjusts the rotation speed of the magnetism runner 13.
Among the above, user tramples steps on wheel 42 in this, this is stepped on wheel 42 and will drive the connector 44 revolution and drive the group It connects block 12 to start to rotate, the assembly block 12 rotation drives the mandrel 11 and the magnetism runner 13 rotation, the magnetism runner 13 can band Windage unit 30a rotation is moved, during the windage unit 30a and the magnetism runner 13 rotate, windage unit 30a's Each windage wing 33a of turbine 31a will increase resistance, so that the rotation speed of the magnetism runner 13 slows down, and then slows down the group and connects The speed that block 12 rotates, meanwhile, the magnetic element 22 in the adjusting seat 21 can attract the magnetism runner 13 with magnetic force, so that the magnetic Property the speed that rotates of runner 13 slow down, and then influence the speed of the assembly block 12 rotation, the rotation of the assembly block 12 slows down with this Connector 44 influences this and steps on wheel 42, and user, which can experience, tramples the resistance for stepping on 42 rotation of wheel.
Among the above, simultaneously reluctance type resistance adjustment device is after being used for a long time for windage of the present invention, if windage unit 30a is damaged It is bad, because windage unit 30a is removably set to the lateral surface of the magnetism runner 13, therefore can by the windage unit 30a from this If the lateral surface of magnetic runner 13 disassembles or the magnetism runner 13 has damage, removably due to the magnetism runner 13 On the assembly block 12, directly the magnetism runner 13 can be disassembled from the assembly block 12 or each magnetic element 22 If there is damage, since the magnetoresistive cell 20 is to be located at outside the magnetism runner 13, and each magnetic element 22 is removably set to The adjusting seat 21 can directly disassemble each magnetic element 22 from the adjusting seat 21, facilitate maintenance or replacement, and at This consideration can only replacement one of them part be replaced without whole group, and the flexibility height of assembling more saves replacement cost, in addition, The magnetoresistive cell 20 can arbitrarily be assembled in either party position of the magnetism runner 13, reduce the limitation of the magnetoresistive cell 20 assembling.
In conclusion windage unit 30a is removably set in windage of the present invention and reluctance type resistance adjustment device The lateral surface of the magnetism runner 13, therefore can be convenient for being disassembled from the magnetism runner 13, in favor of repairing and replacing, and be somebody's turn to do Magnetoresistive cell 20 is set on the bracket 41 and is located at outside the magnetism runner 13, can facilitate and make maintenance activity and replacement operation, Assembling is more convenient, and the windage unit 30a is independent component with the magnetoresistive cell 20 and discriminably dismounts, so replacement should Windage unit 30a and the replacement cost of the magnetoresistive cell 20 can be effectively reduced.
The foregoing is merely the schematical specific embodiment of the present invention, the range being not intended to limit the invention.It is any Those skilled in the art, under the premise of not departing from design and the principle of the present invention made equivalent variations with repair Change, should belong to the scope of protection of the invention.
