Abstract
The utility model discloses a kind of returning device of electronic lock motor, comprise the housing with inner chamber, described inner chamber has opening, being provided with in described inner chamber can the tooth bar of movement in described inner chamber, the engaging tooth of described tooth bar is towards the opening of inner chamber, the one or both ends of described tooth bar are connected with spring, and described spring is resisted against on the sidewall of described inner chamber.This returning device can keep the position of tooth bar relatively stable under the action of the spring, so just can ensure with the initial position of meshed gears relatively stable, thus ensure that the initial position of motor is relatively stable, ensure that the accuracy of the start angle of motor, extend the application life of electronic lock.
Description
Technical field
The utility model belongs to electronic lock technical field, relates to a kind of returning device of electronic lock motor.
Background technology
Electronic lock drives with motor usually, and motor transmits power with gear mechanism.In door opening process, motor can rotate a certain angle, and after locking a door, motor meeting return waits for opening door operation next time, and so forth.After long use, the start angle of motor probably changes, and when opening door operation motor now rotated with former equal angular, may cause opening the door.Therefore ensure that the start angle of motor is very important, the application life of electronic lock can be extended, and the consideration that electronic lock of the prior art design is usually all not relevant.So existing electronic lock has obvious room for improvement.
Summary of the invention
The utility model proposes a kind of returning device of electronic lock motor for prior art Problems existing, and object is the accuracy of the start angle ensureing motor, extends the application life of electronic lock.
The utility model is achieved in that
A kind of returning device of electronic lock motor, it is characterized in that, comprise the housing with inner chamber, described inner chamber has opening, being provided with in described inner chamber can the tooth bar of movement in described inner chamber, the engaging tooth of described tooth bar is towards the opening of inner chamber, and the one or both ends of described tooth bar are connected with spring, and described spring is resisted against on the sidewall of described inner chamber.
In the returning device of above-mentioned a kind of electronic lock motor, described spring has two pieces, is separately positioned on the two ends of described tooth bar.
In the returning device of above-mentioned a kind of electronic lock motor, the two ends of described housing have the circular hole for described spring turnover, and described circular hole is blocked by cover plate.
In the returning device of above-mentioned a kind of electronic lock motor, described cover plate has external screw thread, and described circular-hole internal-wall has internal thread, and described cover plate and described housing are threaded.
In the returning device of above-mentioned a kind of electronic lock motor, the diapire of described inner chamber is provided with roller bearing, bottom surface and the described roller bearing of described tooth bar contact.
The returning device of a kind of electronic lock motor provided by the utility model, during without external force, this returning device can keep the position of tooth bar relatively stable under the action of the spring, so just can ensure with the initial position of meshed gears relatively stable, thus ensure that the initial position of motor is relatively stable, ensure that the accuracy of the start angle of motor, extend the application life of electronic lock.
Accompanying drawing explanation
Fig. 1 is the perspective structure schematic diagram of the utility model returning device.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Present embodiments provide a kind of returning device of electronic lock motor, as shown in Figure 1, comprise housing 100, tooth bar 200 and spring 300.Described housing 100 has inner chamber 110, inner chamber 110 has opening, opening upwards in Fig. 1, opening towards accurate with the position of the gear on motor output shaft, tooth bar 200 to be arranged in inner chamber 110 and can you moves at inner chamber 110, the engaging tooth of tooth bar 200 towards the opening of inner chamber 110, the gear on such motor output shaft just can and tooth bar 200 engage.Spring 300 can be one, also can be two pieces, preferably two pieces.One end of spring 300 is connected on tooth bar 200, and the sidewall of the other end and inner chamber 110 leans.
Described returning device is assembled in after in electronic lock, the gears meshing on the output shaft of tooth bar 200 and motor.When unblanking, the gear on the output shaft of motor turns over certain angle, and band carry-over bar 200 is mobile in inner chamber 110, and compress the spring 300 of one end and the spring 300 of the other end that stretches, motor can turn round if desired, band carry-over bar 200 return.If now the pivotal angle of motor has deviation, the elastic force effect of spring 300 just can be corrected it, reaches the accuracy of the start angle ensureing motor, extends the application life of electronic lock.
Further, the two ends of housing 100 have the circular hole passed in and out for described spring 300, and such spring 300 just can regularly replace, and ensure the rectification ability of spring 300.Circular hole is blocked by cover plate 120, and cover plate 120 has external screw thread, and circular-hole internal-wall has internal thread, and cover plate 120 and described housing 100 are threaded.Certainly, cover plate 120 and housing 100 also can the mode such as clamping or tight fit be connected.Now the inner surface of cover plate 120 is the sidewall of inner chamber 110, the inner surface of spring 300 and cover plate 120 against.
Further, the diapire of described inner chamber 110 is provided with roller bearing 130, bottom surface and the described roller bearing 130 of described tooth bar 200 contact.The motion of such tooth bar 200 is exactly rolling friction, reduces frictional force, strengthens the flexibility of tooth bar 200.
Should be understood that; the foregoing is only preferred embodiment of the present utility model; be not sufficient to limit the technical solution of the utility model; for those of ordinary skills; within spirit of the present utility model and principle; can be increased and decreased according to the above description, replaced, converted or improved, and all these increases and decreases, replacement, conversion or the technical scheme after improving, all should belong to the protection domain of the utility model claims.
