Fig. 2 and Fig. 3 is one embodiment according to the utility model, the movement with manual steering mechanism being shown specifically
The structural schematic diagram of device, including handle 200, steering sprocket 210, conveyer belt 220 (being in the present embodiment chain), upper sprocket wheel
Component 230 and connecting shaft 201.Handle 200 is connected with steering sprocket 210 below, and drives steering sprocket by handle
One end of 210 rotation, conveyer belt 220 is connect with steering sprocket 210, and the other end is connect with cochain wheel assembly 230, steering sprocket
210 rotations drive conveyer belts 220, and then cochain wheel assembly 230 connected to it is driven to rotate, cochain wheel assembly 230 with connect
Axis 201 is coaxially connected, and drives lower sprocket component 250 to rotate by connecting shaft 201, and lower sprocket component 250 passes through driving wheel
Conveyer belt (in the present embodiment be chain 260) drive driving wheel 270 to rotate, user passes through the rotatable drive of rotational handle 200
Driving wheel 270 is to desired direction, to realize the synchronous rotation of handle 200 Yu driving wheel 270.In addition, above scheme is by changing
The length for becoming conveyer belt 220 can easily change the position setting of handle.For example, it is desired to by two handles to device two sides
When outer shifting, it is only necessary to the length for suitably lengthening chain, without changing the layout of electric box electric elements inside.
Optionally, connecting shaft 201 include the upper connecting shaft 202 being connect with cochain wheel assembly 230 and with the lower sprocket group
The lower connecting shaft 203 that part 250 connects is connected between upper connecting shaft 202 and lower connecting shaft 203 by shaft coupling 240, upper sprocket wheel group
Part 230 drives lower sprocket component 250 to rotate by shaft coupling 240.Positioning device is additionally provided on shaft coupling 240, such as fixed
Screw, the opposite steering position for fixed handle 200 and driving wheel 270.When carrying out assembly conciliation, driving wheel 270 is adjusted
To the front position of mobile device, rotating handle 200 to null positions is (for example, the handle direction of handle is towards dead astern, also referred to as
Handle is in zero degree direction), then tightening the fixing screws of shaft coupling 240 realizes right turn handle 200 and rear-wheel
270 directions are consistent, and when rotating handle 200, rear-wheel 270 can be kept and 200 synchronous rotary of handle.Using shaft coupling 240
Later, assembly and adjusting become simply, to have saved working hour, also make the maintenance in later period more convenient.
In addition, the utility model, which also increases on the basis of original device, turns to orienting device 300, specific structure is such as
Shown in Fig. 4 and Fig. 5, turning to orienting device be can be set in the lower section of handle, including the orientation seat being fixed in steering sprocket 210
320 and bearing fixed seat 350, bearing fixed seat 350 be fixed in the rack 400 of mobile device (referring to attached drawing 2), not with
Handle rotation.For the sake of getting across, 400 part of rack, bearing fixed seat 350 are deleted in the structure chart of Fig. 4 and Fig. 5
It is equipped with retention bead and a V-groove, the axis 310 and steering sprocket 210 of handle are connected by screw to, and orientation seat 320 is logical
It crosses screw to be fixed in steering sprocket 210, directional component is fixed on orientation seat 320, and directional component may include spring-loaded plunger
340 or left limit screw 330 or right limit screw 390, the spring for heading on ball, spring are equipped with inside spring-loaded plunger 340
340 surface of plunger is external screw thread, after spring-loaded plunger 340 being screwed into from the threaded hole of the lower section of spring-loaded plunger fixing seat 320, top
The ball in portion can be withstood in the V-groove on bearing fixed seat 350, at this point, user can clearly be perceived by handle, and
And this position can be defined as to handle and be in initial angle or zero degree direction or null positions.User's rotating handle
When, ball is detached from V-groove under the action of rotary force because of meeting back shrinkage after being squeezed, when rotating handle to limit
When screw and retention bead collide, user can clearly perceive, and thus determine the direction of rotation of handle
Reach specific angle.The position of stop screw can be set according to actual needs, for example, stop screw 330 can be set
When encountering the retention bead on bearing fixed seat 350, handle encounters retention bead just at 90 degree of directions, stop screw 390
When, handle encounters retention bead and stops operating just at minus 90 degree of directions, handle.In addition it is also possible to which stop screw is arranged
Positioned at other positions, when so that retention bead being collided with it, user can clearly know that handle is in set angle
Direction.
Compared with the existing technology, in manual steering mechanism disclosed in the utility model, handle passes through steering sprocket, transmission
Band, cochain wheel assembly drive connecting shaft rotation, thus achieve the purpose that control driving wheel turn to, because handle no longer with connecting shaft
It is coaxially connected, it is possible to the position of connecting shaft and steering tiller is set more flexiblely, it can will be occupied by original connecting shaft
Position releases the mounting arrangement for electrical component, and due to no longer stopping electrical member after connecting shaft position change
Part, later period are also more convenient to the maintenance and maintenance of electrical component.In addition, manual steering mechanism disclosed in the utility model
Great flexibility is brought to the setting of the distance between handle, can suitably increase the spacing of two handles, make handle position
Setting be more in line with ergonomics, make user pushing meanss be moved forward and backward or turn to when feel more convenient and easypro
It is suitable.Also, the steering orienting device newly increased be able to use family can clearly perceive handle whether be in zero degree direction or
Person's other angles direction, uses more flexible simplicity.
Some exemplary embodiments are described above.It should be understood, however, that various modifications may be made.Example
Such as, if described system, framework, equipment or component be combined in different ways and/or by other component or its be equal
Object is substituted or supplemented, then suitable result may be implemented.Correspondingly, other embodiments also fall into scope of protection of the claims
It is interior.
