Description
Technical field
The utility model relates to a kind of children trolley, relates in particular to a kind of children trolley anti-skid device.
Background technology
The use of children trolley can effectively reduce the head of a family's labour intensity, facilitates head of a family's trip of looking after children.But also there is certain risk in the head of a family by children trolley look after children when trip, as at some slope pavements, because of inadvertent or certain cause specific, the head of a family's hand has left perambulator, and now children trolley is because Action of Gravity Field can Sliding carriage with three wheels.Children trolley slips the appearance of car situation and brings great danger to the baby, and this case happens occasionally in daily life.
At present the children trolley anti-skid device mainly relies on wheel and installs mechanical locking device additional, but this device is only effective when the head of a family is initiatively dead by lock, and because of carelessness or other cause specifics, failing the situation of timely locked wheel does not have help for the head of a family.
Once we need a kind ofly can to detect automatically whether someone controls vehicle movement, whether determine the device of locked wheel.
The utility model content
In order to overcome the defect in the above-mentioned background technology, the utility model provides a kind of children trolley anti-skid device, and the energy active detecting is also controlled the vehicle locking device.
For achieving the above object, the utility model proposes following technical scheme: a kind of children trolley anti-skid device, comprise supply unit and control setup, described supply unit comprises solar cell, DC/DC change-over circuit and lithium cell, described solar cell passes through described DC/DC change-over circuit to described lithium cell charging, described control setup comprises travel switch, controller, photoelectric switch, touch sensible switch and anti-lock device, described travel switch connects respectively described lithium cell and described controller, described photoelectric switch, touch sensible switch and described anti-lock device all are connected with described controller.
Described solar cell is thin-film solar cells, is installed on the children trolley bicycle shed.
Described anti-lock device is the electromagnetic type anti lock device.
Described lithium cell is cylindrical, is arranged in children trolley hollow frame pipe.
Described DC/DC change-over circuit and described controller are arranged in children trolley hollow frame pipe.
Described photoelectric switch comprises projector and receptor, and described projector and receptor are arranged on children trolley wheel both sides.
Described touch sensible switch is arranged in described children trolley handle.
Compared with prior art, a kind of children trolley anti-skid device of the present utility model has simple in structure, easy for installation, detects accurately safe and reliable advantage.
The accompanying drawing explanation
Fig. 1 is the block diagram of the utility model anti-skid device;
Fig. 2 is the mounting structure structural representation of the utility model anti-skid device;
Fig. 3 is the workflow diagram of the utility model anti-skid device controller.
The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical scheme of the utility model embodiment is carried out to clear, complete description.
A kind of children trolley anti-skid device that the utility model discloses, for preventing that effectively children are sitting in appearance in unwatched go-cart and automatically slip the situation of car, as illustrated in fig. 1 and 2, thin-film solar cells 2, DC/DC change-over circuit 8, lithium cell 7, travel switch 3, controller 6, photoelectric switch 4, touch sensible switch 1 and anti-lock device 5, described DC/DC change-over circuit 8 connects respectively described thin-film solar cells 2 and described lithium cell 5, described travel switch 3 connects respectively described lithium cell 5 and described controller 6, described photoelectric switch 4, touch sensible switch 1 all is connected described controller 6 with anti-lock device 5.
Particularly, described thin-film solar cells 2 is arranged on children trolley bicycle shed 21, when children's go-cart in the sun, described thin-film solar cells 2 absorbs solar powers, and converts thereof into electric energy.
Described DC/DC change-over circuit 8 is arranged in children trolley hollow frame pipe 22, and the electric energy that described thin-film solar cells 2 conversions are come carries out the voltage adjustment, the charging requirement of the described lithium cell 7 of voltage conforms after making to adjust.
Described lithium cell 7 is cylindrical, and is arranged in children trolley hollow frame pipe 22, except being filled with the electric energy that described DC/DC change-over circuit 8 transmits, also whole anti-skid device is powered.
Described travel switch 3 is arranged on 23 belows, described children trolley seat, for detection of inside, seat, whether child is arranged, if have, just connect described travel switch 3, now lithium cell 7 can be to whole anti-skid device power supply, if not disconnect travel switch 3, lithium cell 7 can not powered, saved electric energy.
Described photoelectric switch 4 comprises projector and receptor (not shown), described projector and described receptor are arranged on respectively any wheel of children trolley both sides, when vehicle wheel rotation, constantly replace in wheel wheel disc and space, and photoelectric switch 4 is also replaced in conducting and between disconnecting, form the skip signal of high-low level.
Whether described touch sensible switch 1 is arranged on children trolley handle 24, held for detection of cart handle.
Described anti-lock device 5 is the electromagnetic type anti lock device, is arranged on children trolley trailing wheel 25, and when control circuit transmitted brake signal, described anti-lock device 5 started, and checks trailing wheel it can not be rotated.
In actual applications, if there is child to be seated in children trolley, described travel switch 3 closures, lithium cell 7 is connected with described controller 6, whole anti-skid device starts powered operation, now whether photoelectric switch 4 starts to detect wheel and rotates, if produced the high-low level signal, just mean that wheel is rotating, described photoelectric switch 4 is passed to controller 6 by signal, described controller 6 sends instruction to described touch sensible switch 1, now described touch sensible switch 1 starts to detect the children trolley handle whether someone is holding, if nobody just holds and sends the described anti-lock device 5 of instruction startup by described controller 6, if someone is holding, do not start described anti-lock device.
Be illustrated in figure 3 the controller workflow diagram, after described controller 6 powers on and starts working, first detect the signal of photoelectric switch 4, judge whether the saltus step of high-low level, if there is no saltus step, mean that children trolley is static, without other work, wait for wheel movement.If the saltus step of high-low level detected, mean the children trolley motion, now should detect again touch sensible switch 1, judge whether that someone holds handlebar, if there is the people to hold handlebar, mean that children trolley is in controllable state, unclamp anti-lock device 5, allow the car proper motion, if nobody holds handlebar, mean that children trolley is in the Sliding carriage with three wheels state, described controller 6 sends instruction immediately, the locked wheel of anti-lock device 5, stop the perambulator motion, avoids the appearance of dangerous situation.
The children trolley anti-skid device that the utility model discloses is simple in structure, easy for installation, detects accurately, safe and reliable.
Technology contents of the present utility model and technical characterictic have disclosed as above; yet those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and are done all replacement and modifications that does not deviate from the utility model spirit; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present utility model and modifications, and contained by the present patent application claim.
