Description
Technical field
The utility model relates to remote control parking stall lock manufacturing technology field, especially a kind of clutch overload protecting mechanism that is applied to remote control parking stall lock.
Background technology
Existing remote control parking stall lock all need to drive power transmission shaft by transmission mechanism by motor and rotate, and the blocking arm of remote control parking stall lock is rotated forward or backwards, and motor is generally again by storage battery power supply and by control circuit control rotating.Be obstructed in the process that blocking arm is rotating, the power transmission shaft meeting is stuck, and the electric current of motor will raise and the overload phenomenon occur at this moment, causes the lost of life of motor or damage occurs.Generally, avoid the damage meeting for the protection motor and at the circuit of control motor rotation overload protection is set, when the electric current of motor exceeded the rated current certain value, the power supply that control circuit cuts off motor made motor stalling.
But also can there be following problem in this protected mode, the one, after power transmission shaft is stuck, motor and transmission mechanism all can be subject to larger impact force, this moment, the electric current of motor can increase suddenly, even the overload protection of control circuit works, because the hysteresis of time, in fact also to motor and control circuit injury, in the course of time, will shorten transmission mechanism, the application life of motor and control circuit; The 2nd, after power transmission shaft was stuck, the unexpected increase of current of electric can cause power consumption sharply to increase, and reduced the service time of battery, the application life that also can reduce battery simultaneously.
The utility model content
The technical problems to be solved in the utility model provides a kind of clutch overload protecting mechanism of remote control parking stall lock, can guarantee that motor works in overload free situation, effectively prolongs the application life of motor, control circuit and battery.
For achieving the above object; the technical solution of the utility model is: a kind of clutch overload protecting mechanism of remote control parking stall lock; comprise motor; power transmission shaft; be fixed with driving gear on the output shaft of motor; cover has driven gear on the power transmission shaft; driving gear and driven gear are meshed; it is characterized in that: driven gear is connected with power transmission shaft in the circumferential rotating mode of axial restraint; power transmission shaft is having clutch for clutch control piece and Compress Spring near the other successively cover of driven gear; Compress Spring one end and power transmission shaft form a fixed connection; the other end of Compress Spring withstands on the end face of clutch for clutch control piece away from driven gear; the clutch for clutch control piece is provided with tenon near the end face of driven gear; the end face of driven gear is provided with tongue-and-groove or mortise and matches with tenon on the clutch for clutch control piece end face; the middle part of clutch for clutch control piece offers the radial hole that is roughly V-type; the large end of V-type radial hole is towards driven gear, and power transmission shaft radially is fixed with trundle and matches with described V-type radial hole.
Further improve, described clutch for clutch control piece is provided with two tenons in the symmetric position near the driven gear end face, is evenly equipped with four tongue-and-grooves on the end face of driven gear or four mortises match with two tenons on the clutch for clutch control piece end face.Can make driven gear better drive the rotation of clutch for clutch control piece, the cooperation of the tenon of clutch for clutch control piece and the tongue-and-groove of driven gear or mortise is comparatively reliable.
Further improve, described V-type radial hole runs through the middle part of clutch for clutch control piece, and the trundle two ends are stretched out power transmission shaft and matched with the V-type radial hole of both sides, clutch for clutch control piece middle part respectively.Make trundle more reliable with cooperating of clutch for clutch control piece.
Further improve, the large end of described clutch for clutch control piece middle part V-type radial hole can extend to form the groove that is roughly V-type vertically, and the small end of described V-type radial hole is divided into arc.Both make things convenient for cooperating of trundle and described V-type radial hole, made things convenient for again the installation of clutch for clutch control piece.
Further improve, cover has fixed block and an output gear that fixes with power transmission shaft on the described power transmission shaft, and end face of fixed block and an end of Compress Spring form a fixed connection.Make things convenient for location and installation and the power transmission shaft outputting power of Compress Spring.
Can find out from structural analysis of the present utility model; motor is to pass through driving gear; driven gear; the clutch for clutch control piece; trundle drives the power transmission shaft rotation; driven gear is that the tongue-and-groove that is provided with of the end face by the tenon on the clutch for clutch control piece end face and driven gear or mortise match and drive the clutch for clutch control piece and rotate; the clutch for clutch control piece is to drive power transmission shaft by the V-type radial hole that its middle part is offered with cooperating of trundle to rotate; the clutch for clutch control piece has Compress Spring away from pushing up again on the end face of driven gear; therefore when power transmission shaft is stuck; the rotation of clutch for clutch control piece is so that trundle is mobile on the inclined-plane of described V-type radial hole; trundle is just oppressed the clutch for clutch control piece; the clutch for clutch control piece is oppressed Compress Spring again makes the clutch for clutch control piece move to the direction away from driven gear; the tenon of last clutch for clutch control piece can break away from mortise or the tongue-and-groove on the driven gear end face; make driven gear be in idling conditions, just effectively protected motor to avoid impacting and overload.
On the other hand, because the operating current of motor can not transship, just can protect the element of control circuit injury-free, prolong the application life of control circuit, power consumption can sharply not increase yet simultaneously, can prolong the service time of battery and the application life of battery.
In addition, after the power transmission shaft stuck phenomenon is eliminated, under the effect of Compress Spring, trundle slides onto the small end place of described V-type radial hole, two tenons on the clutch for clutch control piece end face can be inserted in again on two mortises of driven gear end face simultaneously, motor can pass through driving gear, driven gear, clutch for clutch control piece, the rotation of trundle drive power transmission shaft again, return to normal duty, guarantee which kind of situation transmission mechanism is in motor and can both works in overload free situation, prolong the application life of motor.
