Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solution of the present invention.Following embodiment is only used for
Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.
It should be noted that unless otherwise indicated, technical term or scientific term used in this application should be this hair
The ordinary meaning that bright one of ordinary skill in the art are understood.
It is as shown in Figures 1 to 5: a kind of automatic telescopic door handle of the present embodiment, including shell, motor 6 and connecting column 3,
The through-hole through shell is offered on shell, the connecting column 3 is set in through-hole, and the upper end of the connecting column 3 is fixed with door knob
Hand 1, so that handle is located at outside shell, the side of the connecting column 3 is equipped with rack gear 8, and motor 6 is fixed on shell by mounting plate 9
It is interior, gear 7 is arranged on the axis of the motor 6, the gear 7 is engaged with rack gear 8.
Intelligent door lock does not extend out state in closing, since door handle 1 is in, and handle is can not to be rotated
, after user passes through system identification, handle just understands auto-extending under the control of motor 6 and opens the door so that user rotates, specifically
, telescopic process is to be rotated by motor 6, and then the axis of motor 6 is promoted to be rotated, and then the axis of motor 6 drives set
If 6 axis of motor on gear 7 rotated because gear 7 is engaged with rack gear 8, and 6 position of motor be it is fixed, therefore, tooth
It will drive rack gear 8 while 7 rotation of wheel to move up and down, then since rack gear 8 is the side for being fixed on connecting column 3, tooth
Item 8, which moves up and down, can drive connecting column 3 to carry out telescopic moving up and down, in turn, since door handle 1 is to be fixed on connecting column 3
Upper end, thus while connecting column 3 moves up and down, door handle 1 also will do it flexible, and the telescopic location of door handle 1 is equal
It is allowed to be able to maintain in the outside of shell.In above scheme, it can be consolidated by a connecting plate between door handle 1 and connecting column 3
Fixed, specific fixed structure is originally not belonging to the protection scope of this programme, thus has different fixation sides with regard to the structure of different door handles 1
Formula, fixed form have no effect on the implementation of this programme, therefore just do not do in this programme and excessively explain in detail, the skill of this field
Art personnel know how to be fixed.
3 two sides of connecting column are equipped with symmetrical raised line 4, and the through-hole is equipped with to be used for what through-hole end was fixed
The sliding slot 5 of fixed raised line 4.
While in order to be positioned to connecting column 3, that is, prevents it from shaking during telescopic moving and be able to maintain straight
Line operation is arranged symmetrical raised line 4 in the two sides of connecting column 3, and is equipped with and fixes with through-hole end and for fixing on through-hole
The sliding slot 5 of raised line 4, connecting column 3 enable raised line 4 just in sliding slot 5 during the installation process, so that connecting column 3 is flexible
When mobile can along the chute 5 direction moved, further, the bottom end of sliding slot 5 is equipped with the fixation around connecting column 3
Ring 10 is further fixed connecting column 3, herein it is to be noted that the position between rack gear 8 and fixed ring 10 is closed
System, it is required that rack gear 8 can pass through fixed ring 10 without being stuck, and the gear 7 being arranged on 6 axis of motor is needed to be located at and be fixed
On ring 10.
The cavity 2 matched with door handle 1 and for accommodating door handle 1 is offered on the shell.
Design herein is on the one hand to allow door handle 1 that can not carry out when system is to verify by identification
Rotation, after only being verified by identification, door handle 1 can just be stretched out by expanding-contracting action and is detached from cavity 2, can be passed through
The movement unlocked is realized in the rotation of user.The setting of another convenience, cavity 2 can play dust-proof work to the edge of door handle 1
With avoiding being covered with dust all on door handle 1 for a long time when not unlocked.
According to above scheme, the present embodiment additionally provide it is a kind of for controlling the control system of above-mentioned door handle 1, including
MCU, current detection circuit and motor driver, the current detection circuit are embedded in MCU, the current detection circuit connection
Between 6 anode of motor driver and motor, for being detected to 6 electric current of motor；The motor driver input terminal and MCU
Electrical connection, the output end of motor driver are electrically connected with motor 6.
Controlled by MCU whole system, specific control mode is as follows: MCU is supervised by the order to itself
Control, judges whether door lock passes through verifying and reach the state that can normally open, and sends electricity to motor driver if being verified
The order of the operation of machine 6, and then control motor 6 and operated, MCU does not send what control door handle 1 stretched if verifying does not pass through
Order.Through verifying, motor 6 will do it operating, at this point, the further current detecting by being embedded in MCU
Circuit detects the electric current of motor 6, the self-protection function of motor 6 in operational process: if its testing result shows motor 6
Electric current is greater than 150mA, illustrates, motor 6 is in abnormal operational conditions, and current detection value herein can be according to motor 6 not
Self-setting is carried out with model, not uniquely determines value.At this point, closing motor 6.Continue motor if not up to current detection value
6 operation orders.Program starting point is returned to after program.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover within the scope of the claims and the description of the invention.
