As shown in figure 3, wheel group 30 is attached to main body 20, can rotate with respect to main body 20 so that whole hay mover 100 can move on the ground.
Main body 20 is connected with door handle device 10.Main body 20, as the major part of hay mover 100, includes actuating unit 21, blade 22, supports housing 23, from running gear 25.Support housing 23 as the main composition of main body 20, it will be integral for the correlated parts assembly and connection of main body 20.Housing 23 is supported to carry actuating unit 21, door handle device 10 is connected on support housing 23, the connecting rod 11 of specific door handle device 10 is connected on support housing 23.Housing 23 is supported to be formed with cutting chamber 231, blade 22 is contained in cutting chamber 231.Actuating unit 21 includes a prime mover.The major function as hay mover 100 of mowing is realized by main body 20, and actuating unit 21 drives blade 22 rotation to realize the cutting of grass.Prime mover with cutting blade 22 rotation can be engine can also be motor, for meeting the needs of environmental protection it is preferred that prime mover is motor.Set of cells 24 is also included, set of cells 24 provides power for motor in main body 20.Preferably, set of cells 24 user is detachably mounted in main body 20.The set of cells 24 that can more renew when electric power is not enough.Rely on electrical energy drive from running gear 25.The DC powered preferably being provided by set of cells 24, rotating with respect to main body 20 from running gear 25 drive wheel group 30, thus carrying motor mower 100 to automatically move on the ground, making user not need arduously to promote manually hay mover 100.
Control device 40, including a strain gauge element 41 and a controller 42.
When door handle device 10 is by user's push-and-pull, strain gauge element 41 produces the signal of telecommunication changing according to its dependent variable, and controller 42 controls from running gear 25 according to this signal of telecommunication.
As a kind of preferred embodiment, as shown in figure 5, strain gauge element 41 is arranged on door handle device 10, during user's push and pull bar device 10, door handle device 10 produces stress deformation, and strain gauge element 41 detects this stress deformation output signal of telecommunication.Specifically, strain gauge element 41 is arranged on the operating portion 12 of door handle device 10.
As another kind of preferably scheme, strain gauge element 41 is arranged in main body 20.When door handle device 10 receives thrust or the pulling force of user, this active force is transferred to main body 20 by the connecting rod 11 of door handle device 10, so that strain gauge element 41 produces stress deformation.
In general, the motor with cutting blade 22 rotation pass through belt transmission or gear drive driven wheel group 30 rotate thus realize hay mover 100 from walking function.But rotated by a motor belt motor cutting blade 22 and wheel group 30 rotate the power requirement on motor higher and adjustment from the speed of travel when also will on mowing efficiency produce impact.As preferred scheme, include individually from movable motor 251 from running gear 25.Further, controller 42 controls from movable motor 251 according to the signal of telecommunication that strain gauge element 41 produces.
Generally, for conventional hay mover 100 in order to control starting or stoping from running gear 25, it is typically provided with single controlling switch such as trigger.Its complex structure, when there is the mowing electric motor starting trigger and control simultaneous situation of two triggers of trigger from running gear 25, user need to grip two trigger operated inconvenience simultaneously and gripping comfort level is very low in use.

Specifically, user walks forward promotion handle when user's speed of travel is more than hay mover 100 from the speed of travel, door handle device 10 moves relative to main body 20 in the past, actuating unit 21 drives hay mover 100 so that the speed from walking will be accelerated, when hay mover 100 from gait of march substantially identical with user's speed of travel when, hay mover 100 is not further added by from the speed of walking；Otherwise when user's speed of travel is less than hay mover 100 from gait of march, door handle device 10 main body 20 relatively is moved rearwards by, actuating unit 21 drives hay mover 100 to make will be slack-off from the speed advanced, when hay mover 100 gait of march is substantially identical with user's speed of travel, hay mover 100 no longer reduces from the speed advanced.By user control handle and the position of main body 20 in the process of walking, realize the dynamic equilibrium from the speed of travel and user's speed of travel of hay mover 100.
When work to corner or during corner, user generally requires to close the driving that actuating unit 21 stops forward, then pulls back hay mover 100, receding angle backwardness is again started up hay mover 100, and operating process is loaded down with trivial details, and pulls back hay mover 100 and operates arduously.
As a kind of preferred version, actuating unit 21 can not only drive hay mover 100 to travel forward, and can drive hay mover 100 rearward movement simultaneously,
Specifically, actuating unit 21 drives hay mover 100 linearly to move, and when door handle device 10 is in primary importance, hay mover 100 travels forward, when door handle device 10 is in the second position, hay mover 100 rearward movement.
Actuating unit 21 is controlled to realize the conversion being moved forward and backward of hay mover 100 it is not necessary to closing actuating unit 21 rapid operation is convenient by door handle device 10.
Specifically, also there is a centre position between primary importance and the second position, as shown in figure 1, door handle device 10 is in an intermediate position with respect to main body 20.When door handle device 10 is moved from centre position to primary importance, that is, along direction of arrow moving handle device 10 to the left, hay mover 100 is driven to front motion；When door handle device 10 is moved from centre position to the second position, that is, along right-hand arrow direction moving handle device 10, hay mover 100 moves after being driven to.
More specifically, when door handle device 10 moves to primary importance from centre position, the proal speed of hay mover 100 is gradually accelerated, and when door handle device 10 moves to the second position from centre position, the speed of hay mover 100 rearward movement is gradually accelerated.
By user control handle and the position of main body 20 in the process of walking, realize the dynamic equilibrium from the speed of travel and user's speed of travel of hay mover 100.
As a kind of preferred version, hay mover 100 also includes：Position sensor 60, for detecting the position of door handle device 10 main body 20 relatively；Wherein, prime mover at least can be by electrical energy drive, when door handle device 10 is in primary importance, position sensor 60 exports for controlling prime mover to be in first signal of telecommunication of first state, when door handle device 10 is in the second position, position sensor 60 exports for controlling prime mover to be in second signal of telecommunication of the second state.
Existing hay mover 100 generally carries out speed of travel control, complex structure using frame for movement to hay mover 100, and operates underaction accurate.Detect the position of door handle device 10 main body 20 relatively using position sensor 60, hay mover 100 is controlled, structure is simple and operates precisely.
As a kind of preferred version, door handle device 10 position of main body 20 relatively is corresponded with the signal of telecommunication of position sensor 60 output.Position sensor 60 output signal can export different signals such that it is able to realize stepless regulated to hay mover 100 speed of travel by the position control between door handle device 10 and main body 20, the door handle device 10 different position of main body 20 relatively.
As a kind of preferred scheme, also there is between primary importance and the second position centre position, when door handle device 10 moves to centre position, position sensor 60 exports a brake signal making prime mover brake.
When when door handle device 10 is in primary importance, actuating unit 21 drives hay mover 100 to travel forward, it is in actuating unit 21 during the second position and drive hay mover 100 rearward movement, when centre position, actuating unit 21 does not drive hay mover 100 to move, when hay mover 100 travels forward, having an inertia makes hay mover 100 move forward, when needing to stop hay mover 100, door handle device 10 main body 20 relatively is moved to centre position, now actuating unit 21 does not drive hay mover 100 to move, hay mover 100 stops after continuing on a segment distance under effect of inertia.In order that hay mover 100 quickly stops, it is to avoid in case of emergency because the impact of inertia can not timely stop hay mover 100 and produce danger.Position sensor 60 when door handle device 10 main body 20 relatively is centrally located, that is, user need to stop hay mover 100 from when advancing, output one makes the brake signal that prime mover brakes, and makes hay mover 100 emergent stopping avoid danger.
Hay mover 100 also has other functions it is therefore desirable to single control device.As the common function required for user, hay mover 100 is advanced sometimes for turning to when advancing, and now needs another one control device for controlling the steering of hay mover 100,
As a kind of preferred version, hay mover 100 includes：Pressure transducer 50, for detecting the pressure being subject to；Wherein, door handle device 10 includes for the operating portion 12 for user operation, and pressure transducer 50 is bonded to door handle device 10；When operating portion 12 is subject to first pressure, pressure transducer 50 exports the first control signal makes hay mover 100 be in the first mode of operation, when operating portion 12 is subject to second pressure, pressure transducer 50 exports the second control signal makes hay mover 100 be in the second mode of operation.
As a kind of preferred scheme, pressure transducer 50 detects that user is applied to the pressure of operating portion 12, is the pressure producing during user's push-and-pull operating portion 12.
As another kind of preferably scheme, pressure transducer 50 detects that user is applied to the pressure of operating portion 12, is that user holds with a firm grip the pressure of holding with a firm grip of operating portion 12 generation.
Specifically, hay mover 100 first mode of operation can be used for steering to the left, and the second mode of operation is steering backward.Pressure transducer 50, according to the difference of operating portion 12 pressure at both sides, controls hay mover 100 to turn to.During the pressure being specifically subject on the right side of the pressure being subject on the left of pressure transducer 50 detects hay mover 100 operating portion 12 is more than operating portion 12, actuating unit 21 drives hay mover 100 to turn to the right traveling；During the pressure being subject on the left of the pressure being subject on the right side of pressure transducer 50 detects hay mover 100 operating portion 12 is more than operating portion 12, actuating unit 21 drives hay mover 100 to turn to traveling to the left.
As a kind of preferred version, door handle device 10 slidably connects to main body 20, and door handle device 10 slides between the first position and the second position with respect to main body 20；Door handle device 10 slides approximately along the direction of motion of hay mover 100.
Specifically, door handle device 10 slides along the direction that hay mover 100 is advanced.
Slip between door handle device 10 and main body 20 is to slide along the direction that hay mover 100 is advanced.The power that user is applied to door handle device 10 directly acts on door handle device 10 direction of hay mover 100 main body 20 motion relatively, and door handle device 10 enters line slip with respect to main body 20 only needs less power can produce larger displacement.Rapid operation, and control precisely.
The basic principles, principal features and advantages of the present invention have been shown and described above.It should be understood by those skilled in the art that, the invention is not limited in any way for above-described embodiment, all technical schemes being obtained by the way of equivalent or equivalent transformation, all falls within protection scope of the present invention.
