It comes to harm.
Be also provided with identification module in the control centre 9 of the present apparatus, can the information that transmits of identification and detection device 31,
It is close to judge whether there is dog.Also, the identification module of the present apparatus is provided with database, and database is stored in SD card.User can
To regularly update the database in SD card, so that the identification function of the present apparatus gets a promotion, can identify a greater variety of
Dog.
Detected dog close to when, the control module of control centre 9 just will start the first cylinder 5 work.First
Cylinder 5 rapidly releases piston rod 51, and piston rod 51 hits pressure block 44, to bring kinetic energy to pressure block 44, this just makes
Pressure block 44 is obtained to move.44 movement of pressure block will make shield 41 quickly rotate, such 41 energy of shield
It is enough to cover the opening of infant compartment, prevent dog from touching the child in infant compartment.And this shield 41 be it is transparent, name and on
Face is provided with several air holes, therefore child is to be unaffected.While the starting of the first cylinder 55, control module meeting
Start supersonic generator 11 to work.Supersonic generator 11 issues the ultrasonic wave that human ear can not be heard, this ultrasonic wave
Frequency, which belongs to dog ear, to be heard, and in the range of can extremely feel bad after hearing.Therefore, close dog is hearing this frequency
It, will be far from perambulator after the ultrasonic wave of rate.
The present apparatus is also provided with several medicine storehouses 8, and raised line outstanding is in addition arranged on medicine storehouse 8, is fastened on chassis 2
In groove, then medicine storehouse 8 is limited rotation, so being merely able to move up and down., can place in medicine storehouse 8 it is some enable dog fear and
The irritation article of detest, such as a kind of capsicum of high-purity purify element.While shield 41 starts work, the present apparatus
Rotating base 15 opens rotation, because the relationship being threadedly coupled, will drive medicine storehouse 8 to move up, thus prominent chassis 2, to
Upper process.At this point, fan 83 opens work, dry towards medicine storehouse 8, just blows out the smell of article in medicine storehouse 8.This is smelt in dog
When a little smells, it can feel bad very much, therefore psychology can generate and fear sense, so perambulator will rapidly be fled from.
The present apparatus is also provided with smoke barrier, and the smell of article in medicine storehouse 8 can be prevented to be raised above, and acts on infant compartment 4.
In addition, the height in medicine storehouse 8 is lower, thus it is smaller on people's influence, and people are when smelling this smell, it will be able to it anticipates
Know and situation has occurred at perambulator, will come rapidly to inspect.Thus the present apparatus being capable of automatic protection child.
Furthermore, it is possible to which red will be blown out when fan is blown by placing red powder in a wherein medicine storehouse 8
Smog, warn adult.
Alarm device is also provided in the present apparatus.
During shield 41 rotates, because pressure block 44 is convex shape relative to the outer surface of shield 41
, so motion bar 71 will be pushed.Motion bar 71 can compress the air bag in the alarm pars stridulans 7 after being pressed down, at this point,
Air in air bag is just sprayed from outlet, and exporting has alarm device, then when air-flow quickly sprays, will issue the alarm to scream
Sound warns big people to pay attention to the safety of child.
The present apparatus is also provided with manual start switch, and start button 62 is provided with below hand lever 61, it is found that different
Reason condition, and when perambulator not yet detects, it can be manually pressed by this start button 62, the safety for starting the present apparatus is protected
Protection unit is covered the opening of infant compartment with shield 41, protects child.
The present apparatus is also provided with the glove storehouse 34 for placing article.Because people are when using perambulator, typically
Outdoor situation.Therefore several glove storehouses 34, which are arranged, prevents some articles when can facilitate people zero, such as the water drunk, paper
Towel etc.
Hand handle 421 is provided on shield, can aspect people's opening protection function cover 4, child is embraced.
In order to consider safely, the present apparatus is provided with LED light strip also on wheel.What LED light strip can be rolled in wheel 12
When, light is issued, the bottom surfaces near perambulator can be illuminated in some dark places, avoid perambulator by rugged
Bottom surface so that the child lain in infant compartment experience it is uncomfortable.
When shield 41 rotates, there can be one energy impact, in order to alleviate this energy impact, the present apparatus
It is just provided with briquetting 42 and pressure-bearing portion 33 works in coordination.The cushion 331 of buffer function, briquetting 42 are provided in pressure-bearing portion 33
Rotation, which is pressed on the cushion 331, absorbs energy by cushion 331.
The present apparatus also has latch functions, specifically, covers behind pressure-bearing portion 33 in the rotation of shield 41, in briquetting 42
Activity locking part 422 will enter in lock chamber, and end can be pressed on lockup switch to trigger lockup switch.At this point,
Lockup switch drives locking rod to pop up, in locking rod insertion locking hole 424 thus by the movement of locked activity locking part 422, because
This, which allows for shield 41, can not leave pressure-bearing portion 33, so just completing locking work.The activity of locking rod, can use
Cylinder pushes, or is carried out using the magnetic force of magnet, or spring cooperation magnet is taken to carry out.
The present apparatus is provided with wireless transport module, can be connected with the mobile phone of parent by wireless transport module, this sample
Any working condition of device, parent can be understood by mobile phone.Also, after locking work starting, in order to as much as possible
Child is protected, latch functions can be released without switch on vehicle frame, be merely able to be unlocked by mobile phone, greatly increase
Safety.
Also, it uses for convenience, the fingerprint identification module is provided in start button 62, fingerprint recognition can be passed through
Module identifies parent.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
Subject to, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that each fall within of the invention
Protection scope.
The present invention is ingenious in design, has safety device, can be when detecting danger, automatic starting protection vehicle
Interior child, and have and drive dog device, dangerous dog can be driven, and will not impact to other biological.
