Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention made concrete introduction.
With reference to shown in Fig. 1, hay mover 100 includes main frame 1 and operating mechanism 2, wherein main frame 1 includes: prime mover (figure do not mark) and realized the attachment (figure is not marked) of mowing function by prime mover driven, prime mover also including, one makes it operate to drive the activate switch of attachment (figure is not marked), activate switch includes: starting state and halted state, when it is positioned at starting state, prime mover driven attachment works, when it is positioned at halted state, prime mover stops driving attachment.
Operating mechanism 2 is for supplying user operation, comprising: handlebar stem 21, trigger member 22 and switching mechanism 30.Wherein handlebar stem 21 is connected with main frame 1, for promoting whole hay mover 100 to walk on the ground for user.Trigger member 22 and switching mechanism 30 are for being in starting state or halted state for user operation to trigger activate switch, and what wherein trigger member 22 rotated is connected on handlebar stem 21, convenient operation.
With reference to shown in Fig. 2 to Fig. 7, switching mechanism 30 is arranged on handlebar stem 21, comprising: housing the 31, first switch block 32, button 33, plug-in unit the 34, first slide block the 35, second slide block the 36, second switch block 37 and the first elastic component 38.
Housing 31 is fixedly installed on handlebar stem 21, forms a host cavity 311 in housing 31.First switch block 32 is contained in the host cavity 311 in housing 31, and the first switch block 32 is formed a slot 321a.Button 33 can rotate relative to housing 31 with first axle X for axle, and button 33 is partially embedded in host cavity 311, button 33 be positioned at the part outside host cavity 311 for for user operation.Plug-in unit 34 has insertion end 341 and operating side 342, insert in end 341 is inserted into housing 31 and stretch in the slot 321a of the first switch block 32, operating side 342 for for user operation so that the end 341 that inserts of plug-in unit 34 is inserted in slot 321a or makes plug-in unit 34 entirety to be separated from the housing 31 of shutting mechanism 30.First slide block the 35, second slide block 36 and the second switch block 37 are respectively positioned in the host cavity 311 of housing 31, wherein, first slide block 35 can slide relative to housing 31 by M in the first direction, second slide block 36 can slide relative to the first slide block 35 by M in the first direction, and the second switch block 37 can rotate relative to the second slide block 36 with the second axis for axle.First elastic component 38 can produce the elastic force of M in the first direction when by oppressing, and it is connected between the first slide block 35 and the second slide block 36.Wherein, first axle X and the second axis are parallel to each other, and first direction M is perpendicular to first axle X.
Wherein, when the insertion end 341 of plug-in unit 34 is inserted in slot 321a, the first switch block 32 can be along with the first turned position of button 33 synchronous axial system to relative housing 31 and the second turned position.First switch block 32 can make the second switch block 37 be in the locked position when turning to the first turned position, first switch block 32 can make the second switch block 37 be in the unlocked position when turning to the second turned position, and the position relative to housing 31 will be limited on the second slide block 36 M in a first direction when the second switch block 37 is in the locked position, and the second slide block 36 is made to move relative to housing 31 by M along a first direction when the second switch block 37 is in the unlocked position.
nullSo，After the insertion end 341 of plug-in unit 34 is inserted in slot 321a，Pressing button 33，First switch block 32 can turn to the second turned position along with button 33，Thus the first switch block 32 makes the second switch block 37 be positioned at unlocked position，If at this moment triggering the first slide block 35 M along a first direction to slide relative to housing 31，So the first elastic component 38 between the first slide block 35 and the second slide block 36 produces the elastic force of a M in the first direction，And under the effect of this elastic force，Second slide block 36 M along a first direction slides relative to the first slide block 35，If the second slide block 36 in switching mechanism 30 can directly trigger when sliding and be in the activate switch of halted state and switch to starting state，The most at this moment driven by the first elastic component 38 and have occurred and that the second slide block 36 of slip makes activate switch switch to starting state，Thus the work of prime mover driven attachment.
Switching mechanism 30 is provided with plug-in unit 34, after only the insertion end 341 at plug-in unit 34 is inserted in slot 321a, the first switch block 32 can be made along with button 33 synchronous axial system is to the second turned position, and when the insertion end 341 not having plug-in unit 34 or plug-in unit 34 is not inserted in the slot 321a of the first switch block 32, first switch block 32 then can not be along with button 33 synchronous axial system, thus activate switch can not be made to be switched to starting state by halted state, so it can be avoided that hay mover 100 accidental activation caused by maloperation, it is ensured that the security performance of hay mover 100.
This switching mechanism 30 arranges first elastic component 38 between the first slide block 35 and the second slide block 36, drive the second slide block 36 to move by elastic force produced by the first elastic component 38, and only the second slide block 36 could slide when the second switch block 37 is positioned at unlocked position.As can be seen here, the slip of the second slide block 36 needs to meet two conditions: one is that the first slide block 35 occurs the elastic force making the first elastic component 38 produce M in the first direction of sliding；Two is that the second switch block 37 is positioned at unlocked position.nullTherefore，Triggering activate switch switches to starting state and also has another operation order also to be able to realize，I.e.: after the insertion end 341 of plug-in unit 34 is inserted in slot 321a，First triggering the first slide block 35 makes the first elastic component 38 produce the elastic force of a M in the first direction，But now because the second switch block 37 is in the locked position，Thus the second slide block 36 can not slide by relative first slide block 35 M in the first direction，Press button 33 the most again，First switch block 32 turns to the second turned position along with button 33，Then the first switch block 32 makes the second switch block 37 be positioned at unlocked position，At this moment，First elastic component 38 has had elastic force，Therefore，It is positioned at unlocked position once when the second switch block 37，Under the effect of the elastic force of the first elastic component 38, the second slide block 36 M the most in the first direction slides，Enable to activate switch the most equally and switch to starting state.
Therefore, this switching mechanism 30 make the first slide block 35 occur the operation sliding and pressing button 33 there is no sequencing.Therefore, in addition to meeting an action except inserting plug-in unit 34, also need to two actions and can realize on the basis of activate switch switches to starting state, the operation of two actions order the most in no particular order, and then on the basis of ensureing safety, also facilitate the operation of user.
