Description

Perambulator freewheel decision maker
Technical field
The present invention relates to a kind of perambulator freewheel decision maker, belong to perambulator performance test field.
Background technology
In recent years, children's electric motor vehicle (being also referred to as children's battery truck) is active in the Live Sites in domestic each large, medium and small city, residence district.As emulation driving instrument, electric children vehicle can temper sense of direction and the driving technology of child, does not lose interest again, be just subject to the favor of more and more young Chinese father and mother at present while improving the hand of children, eye, brain perception.Electric children vehicle product is comprehensive simulated real car in outward appearance, manipulation, and this feature has just in time catered to the trend of toy industry " to the development of emulation adult articles for use ".
Perambulator is children's product typical case and general product the most, accounts for the share of about 20% in whole children's product consumption.Along with global economy is recovered gradually from financial crisis, electric children vehicle also will constantly increase in the ratio of perambulator industry.Electric children vehicle mainly relies on internal battery to drive, and it is also long that product is suitable for the age---from after 24 months to 14 years old.Typical Representative has four-wheel automobile moulding electric children vehicle and motor tricycle moulding electric children vehicle.
Electric children vehicle carrying children body weight, there is electric power, can by the characteristic of children from row cutting, make it should be carried with higher requirement in security, and due to the reason of seat height, particularly the four-wheel electric perambulator of foot's closing form cannot provide brake with pin, and electric children vehicle is when facing slope or emergency, very important beyond doubt to the requirement of its automatic performance.In world's main standard systems such as U.S.'s toys standard, European toys standard, Japanese toys standard, all strict demand is proposed to the braking quality of electric children vehicle.Specify in standard, band freewheel machinery or power-actuated rider toy must have brake.The judgement whether having a freewheel to perambulator is important component part wherein.If perambulator is proved to be motor itself can provide enough brakes, namely toy is not with freewheel, and toy separately can not equip brake.When meeting following requirement, motor is considered to provide enough brakes:
According to motor brake performance-slope test, vehicle average velocity is less than or equal to 0.36m/s (1.3km/h), or
According to motor brake performance-horizontal checkout, meet the following conditions:
FT1 >=(M+25) × 1.7, or
FT2≥(M+50)×1.7
Wherein:
FT1 represents that for the maximum pull on less than 36 months children's toys, unit is newton;
FT2 represents that for the maximum pull on 36 months and above children's toy, unit is newton;
M represents the quality of toy, and unit is kilogram.
Motor brake performance-inclined-plane test:
Apply the load of regulation to toy, be placed on 10 °± 1 °, surface coverage has sand paper P60(aluminium oxide) inclined-plane on.Make the longitudinal axes parallel of toy in inclined-plane.Allow toy roll down inclined-plane, distance toy starts transfer point 1m place and starts to measure its average velocity in the distance of 2m.
Motor brake performance-horizontal checkout:
To toy apply regulation load, measuring it has sand paper P60(aluminium oxide in surface coverage) surface level on the constant speed movement of (2 ± 0.2) m/s need pulling force.
At present, the test of freewheel is mainly completed by the mode of manual detection by testing staff, to waste time and energy and metrical error is large, lack the checkout equipment of accurate quantification.
Summary of the invention
For the defect that prior art exists, the object of this invention is to provide a kind of perambulator freewheel decision maker, carry out the braking quality test of children electric perambulator according to world's main standard system, detect electric children vehicle itself and enough brakes can be provided, and then determine whether to there is freewheel.
For achieving the above object, design of the present invention is:
In test process, drive chain wheel drive driving-chain by servomotor, control the test speed that motor speed makes driving-chain reach predetermined, pass to the speed that perambulator is constant and stable.Tensioning system prevents sprocket wheel from bending because bearing a heavy burden and causes velocity deviation, ensures velocity level as far as possible, and detects the real-time speed size of driving-chain by scrambler.The left end of force snesor is connected to the bumper of test perambulator and fixes, the other end is connected on aluminium alloy post, when testing the relative driving-chain of perambulator and moving, force cell starts stressed, by being connected to computer record and showing the size of power, realize force value when measuring predetermined speed, thus carry out the judgement of freewheel.
According to foregoing invention design, the technical solution used in the present invention is as follows:
A kind of perambulator freewheel decision maker, comprise base plate, loading ramp, channel-section steel, rolling bearing, driven shaft, safety barrier, web member, force snesor, force snesor fixture, aluminium alloy post, channel-section steel erecting frame, scrambler, P60 sand paper, driving-chain, shaft coupling, reductor erecting bed, reductor, servomotor, main drive shaft, drive sprocket, driven sprocket, described channel-section steel erecting frame is fixed on base plate, fixes channel-section steel directly over channel-section steel erecting frame; Described reductor erecting bed is fixed on base plate, described reductor is fixedly connected with reductor erecting bed, the axle head of described servomotor connects reductor, one end of described main drive shaft is connected by shaft coupling with the axle head of reductor, two ends and the rolling bearing be arranged in channel-section steel of described main drive shaft realize rotary motion, transmitting torque is connected by key between main drive shaft with drive sprocket, described drive sprocket connects driven sprocket by driving-chain, described driven shaft is connected by key with between driven sprocket, between main drive shaft and driven shaft, driving-belt is provided with P60 sand paper; Described loading ramp is fixed on base plate, and its top, slope contacts with driving-belt; Described aluminium alloy post and channel-section steel upper surface are fixed, and described force snesor one end is connected with aluminium alloy post by force snesor fixture, and the other end is connected with tested perambulator by web member; Described scrambler is arranged on the other end of main drive shaft; Described safety barrier is bolted and is fixed on channel-section steel.
In test process, tested perambulator is pushed to test platform along loading ramp, force snesor be connected to the bumper of perambulator and fix, regulate aluminium alloy post height to ensure the level of force snesor, start servomotor, test perambulator starts mobile under the friction force effect of driving-belt, the rotating speed of servomotor is regulated by the speed of encoder feedback, reach default rotating speed, then by the pulling force size suffered by force snesor record, realize the judgement of freewheel.
The present invention compared with the prior art, has following apparent high-lighting feature and remarkable technical progress:
The present invention can measure the size of the pulling force when specified loads, constant speed movement required for tested perambulator fast and accurately, the dynamometry effectively avoiding perambulator to produce because speed is unstable is forbidden problem, and computer can be connected to carry out Real-Time Monitoring, can greatly improve space availability ratio, detection efficiency, accuracy of detection.Under the situation of the relative ground static of perambulator, carry out the horizontal checkout of motor brake performance, there is precision high, time-consuming few feature.
