Description
Technical field
The utility model is related to new-energy automobile field, more particularly to a kind of vehicle sensed based on children's seat interface
Intelligent child lock.
Background technology
With the progress of society, the continuous improvement of people's living standard, automobile more and more comes into more families.
Car door safety lock structure primarily to protection children and design, be in order to avoid among driving conditions, children are because good
The reasons such as the strange heart cause certain danger by mistake by car door opening.Nowadays most of family expenses vehicles are provided with the automatic work(that latches
Can, speed per hour can all latch automatically more than 20km/h or so, as long as but stirring the lock ring by door handle just can easily unlock, this
The children of " clever " are can't beat completely.
Traditional children lock basic structure is mounted on the back door lock of automobile, after children's locking is closed, corresponding heel row car
Door i.e. can not be from in-car opening, it is to avoid the vehicle danger that children open car door and caused in the process of moving.However, traditional children
It can only be opened after being locked in closure outside car, often occur following scene during routine use：Baby is sitting in child lock closure
Car door side, mother first must get off from opposite side car door, around car half cycle after getting off, and go to the outside that locked door and open car again
Door, also needs child lock reversing open mode before closing the door, operates very inconvenient.
In addition, for the type of drive of child lock, hand driving lever formula structure is used existing low and middle-end vehicle child lock more,
Some high-end vehicles employ electronic child lock, and electrodynamic type is needed also remain for by driver in driving cabin button operation, it is impossible to realized
Full intellectuality.
Utility model content

The impact very little caused during door handle to motor, motor service life is long.
4）Car steering position sets child lock switch, the switch of child lock can be directly controlled by driver, when children get off
More convenient operation.
5）Sliding block is provided with the ball being radially arranged along swing arm, reduces the coefficient of friction between sliding block and arc chute,
So as to effectively increase the regularity and stability of latch translational motion, while also reducing the load of motor, increase
The continuation of the journey of new energy car battery.
6）The diameter of work shape support termination is more than the width of arc chute, and the spacing of work shape support two ends is slightly larger than locking
The thickness of block, it is ensured that the latch of chute both sides is stuck between the two ends of sliding block just, can be prevented effectively from sliding block sliding process
In shift in addition depart from chute, the stability of slide construction is further increased, so as to extend the use of whole lockset
Life-span.

Embodiment
The technical solution of the utility model, but protection domain of the present utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to as described below.
As shown in figure 1, the Vehicular intelligent child lock sensed based on children's seat interface, including it is arranged on children's seat interface
On pulling force inductor, microcontroller, motor 3 and lock assembly, described children's seat interface is LATCH interfaces
Or ISOFIX interfaces.The pulling force inductor is connected by wireless communication module with the sampled signal input of microcontroller,
The control signal output of microcontroller is connected with the drive circuit of motor 3.According to the pulling force on children's seat interface
Whether sensing automatic discrimination children's seat has taken children, if taking has children（The value of thrust after children is taken than simple one
Value of thrust during individual children's seat is big）, pulling force, which senses, detects value of thrust more than predetermined threshold value, automatically controls motor 3
Working condition, and then the opening or locked of child lock is realized, improve intelligence degree.
As shown in Figures 2 and 3, described lock assembly includes latch 1, locking projection 2 and swing arm 4, described locking
Projection 2 is fixedly mounted in car door lock rotating shaft 5, and the deformation of locking projection 2 is avoided to increase the service life or is departed from, locking is raised
2 are preferably able to use integrated forming technique with car door lock rotating shaft 5.The latch 1 is provided with what is be engaged with locking projection 2
Neck 6；One end of the swing arm 4 is fixedly mounted on the output shaft of motor 3, and the other end of swing arm 4 is provided with sliding block 7, lock
Stops 1 is provided with the arc chute 8 being engaged with sliding block 7.As shown in figure 5, the radius R of arc chute 8 should be more than sliding block 7
Radius of turn r, so just be can guarantee that when sliding block 7 horizontally slips in arc chute 8, and latch 1 can be pushed away in the radial direction of sliding block 7
Translated up or down under power effect.
The radius R of arc chute 8 is more than the radius of turn r of sliding block 7, the arcuately center of chute 8 of sliding block 7（On the right side of Fig. 4
Figure）To its two ends（Such as Fig. 4 left hand views）During slip, the overall opposite direction to locking projection 2 of latch 1（It is downward in figure）Move
Dynamic, neck 6 progressively disengages locking projection 2.As shown in figure 4, sliding block 7 arcuately the two ends of chute 8 thereto the heart slide when, latch
1 is overall to the direction of locking projection 2（It is upward in figure）Mobile, neck 6 gradually puts locking projection 2 and forms locking.Pass through
Motor 3 and large radius arc chute 8 coordinate the driving realized to locking structure, ingenious in design, simplify children's lock construction,
Cost is reduced, structural stability and reliability is improved.
Further, as shown in fig. 6, described sliding block 7 includes work shape support 7.1 and a ball set, ball set is by edge
Symmetrically arranged two balls 7.2 of radial direction of swing arm 4 are constituted, during sliding block 7 horizontally slips in arc chute 8, sliding
Between block 7 and chute all the time by ball 7.2 points contact.Described ball 7.2 is arranged on work shape support 7.1 by bearing shell 7.3
Wall on, ball 7.2 and the gap of bearing shell 7.3 coordinate, the wall Interference contact of ball 7.2 and arc chute 8.Sliding block 7 is provided with edge
The ball 7.2 that swing arm 4 is radially arranged, reduces the coefficient of friction between sliding block 7 and arc chute 8, so as to effectively increase lock
The regularity and stability of the translational motion of stops 1, while also reducing the load of motor 3, adds new-energy automobile electricity
The continuation of the journey in pond.
As a further improvement, as shown in fig. 6, the diameter of the termination of work shape support 7.1 is more than the width of arc chute 8
Degree, the spacing of the two ends of work shape support 7.1 is slightly larger than the thickness of latch 1.Ensure that the latch 1 of chute both sides blocks just with this
Between the two ends of sliding block 7, it can be prevented effectively from the sliding process of sliding block 7 and shift or even depart from chute, further improve
The stability of slide construction, so as to extend the service life of whole lockset.
Described above is only preferred embodiment of the present utility model, it should be understood that the utility model is not limited to herein
Disclosed form, is not to be taken as the exclusion to other embodiment, and available for various other combinations, modification and environment, and
It can be modified in contemplated scope described herein by the technology or knowledge of above-mentioned teaching or association area.And this area
The change and change that personnel are carried out do not depart from spirit and scope of the present utility model, then all should be in right appended by the utility model
It is required that protection domain in.
