the elastic motor lock comprises a limiting piece 2, a fixed end 22 of the limiting piece 2 is fixedly connected with the inside of the fixed part 11 through a screw, a first protrusion 211 and a second protrusion 212 are arranged at an elastic end 21 at the other end of the limiting piece, and the distances from the first protrusion 211 and the second protrusion 212 to the axis of the motor shaft are equal; the rotating part 12 is provided with a lock column 121, and a cylindrical shaft body of the rotating part 12 with the lock column 121 is sleeved on the outer ring of the motor shaft;

the spatial positions of the first protrusion 211 and the second protrusion 212 are on the motion track of the lock cylinder 121 driven by the rotation of the rotating part 12, and the limit space 213 formed by the first protrusion 211 and the second protrusion 212 is used for accommodating the lock cylinder 121, i.e. for limiting the relative rotation of the rotating part 12 and the fixing part 11 of the motor; the contact surface of the lock cylinder 121 is an arc-shaped structure (i.e., a surface that contacts the first protrusion 211 or the second protrusion 212 during the locking and unlocking of the motor). When the lock cylinder 121 enters the limiting space 213, the first protrusion 211 and the second protrusion 212 can respectively limit the clockwise rotation and the counterclockwise rotation of the limiting block 121, so as to limit the rotation of the rotating part 12 relative to the fixing part 11, and the arc-shaped contact surface can reduce the external force applied by a user in the locking or unlocking process, so that the abrasion is small.

The specific locking process is as follows:

clockwise locking: as shown in fig. 1 to 2, at an initial moment, the lock cylinder 121 is located at the left side of the first protrusion 211 (i.e. located outside the limiting space 213), the rotating portion 12 drives the lock cylinder 121 to rotate clockwise under the action of an external force, and presses the first protrusion 211 on the elastic end 21 to elastically deform the first protrusion 211, so that the lock cylinder 121 rotates to the limiting space 213, the external force acting on the first protrusion 211 disappears, the stopper 2 recovers to its original shape, and the lock cylinder 121 is located in the limiting space 213 all the time without the action of the external force, thereby locking the motor; locking in the counterclockwise direction: at the initial moment, the lock cylinder 121 can also be located on the right side of the second protrusion 212, the rotating part 12 drives the lock cylinder 121 to rotate anticlockwise under the action of external force, the second protrusion 212 on the elastic end 21 is extruded to be elastically deformed, the lock cylinder 121 rotates to the limiting space 213, the external force acting on the second protrusion 212 disappears, the stopper 2 recovers the original shape, the lock cylinder 121 is located in the limiting space 213 all the time under the action of no external force, and the locking of the motor is realized.

Unlocking in the clockwise direction: the rotating part 12 is rotated clockwise, the lock column 121 extrudes the second bulge 212 on the elastic end 21 to enable the second bulge to generate elastic deformation, the lock column 121 is separated from the limiting space 213, the external force acting on the second bulge 212 disappears, the retainer 2 restores the original shape, and the unlocking of the motor is realized; unlocking in the counterclockwise direction: the rotating part 12 is rotated counterclockwise, the lock cylinder 121 extrudes the first protrusion 211 on the elastic end 21, so that the first protrusion is elastically deformed, the lock cylinder 121 is separated from the limiting space 213, the external force acting on the first protrusion 211 disappears, the stopper 2 recovers the original shape, and the unlocking of the motor is realized. The elastic motor lock in the embodiment has the advantages of simple structure and relatively low manufacturing cost, can realize the locking and unlocking of the motor without a limiting structure in the prior art, and can realize the locking and unlocking in two directions.

The above embodiment exemplarily shows the connection relationship between the fixed end 22 and the fixing portion 11, and the fixed connection relationship between the fixed end 22 of the stop member 2 and the fixing portion 11 can be replaced by welding, gluing, screws and screw holes, etc. according to other embodiments or practical applications.

The above embodiment exemplarily shows that the contact surface of the lock cylinder 121 is an arc-shaped structure, according to other embodiments or practical applications, the contact surfaces of the first protrusion 211, the second protrusion 212 and the lock cylinder 121 may be arc-shaped contact surfaces, or the contact surfaces of the first protrusion 211, the second protrusion 212 and the lock cylinder 121 are all arc-shaped contact surfaces in the unlocking or locking process, and the like, so as to reduce the acting force of locking and unlocking and reduce the wear between components; as shown in fig. 8(a), 8(b), and 8(c), the contact surface of the lock cylinder 121 may also be replaced by a slope, for example, the lock cylinder 121 has a structure of triangle, trapezoid, or a combination of trapezoid and arc, or the contact surface of the first protrusion 211, the second protrusion 212 and the lock cylinder 121 may also be replaced by a slope, for example, the first protrusion 211 or the second protrusion 212 has a structure of triangle, trapezoid, or a combination of trapezoid and arc.

The above embodiment exemplarily shows the distances from the first protrusion 211 and the second protrusion 212 to the axis of the motor shaft, according to other embodiments or practical applications, the distances from the first protrusion 211 and the second protrusion 212 to the axis of the motor shaft may also be unequal, and the specific distance is related to the elasticity of the elastic end 21 of the stopper 2, and is not specifically limited herein, as long as the first protrusion 211 and the second protrusion 212 can rotate the lock cylinder 121 into the limit space 213 under the elastic force of the elastic end 21, and both directions of locking and unlocking can be achieved.

In another embodiment, as shown in fig. 3, 4 and 7, in addition to the above embodiments, the distance from the second protrusion 212 to the axis of the motor shaft is greater than the distance from the first protrusion 211 to the axis of the motor shaft, wherein the second limiting protrusion 212 plays a role of a stop in the resilient motor lock of the present embodiment, that is, the second limiting protrusion 212 is a stop.

The specific locking process is as follows: as shown in fig. 3 to 4, at an initial moment, the lock cylinder 121 is located at the left side of the first protrusion 211 (i.e. located outside the limiting space 213), the rotating portion 12 drives the lock cylinder 121 to rotate clockwise under the action of an external force, and presses the first protrusion 211 on the elastic end 21 to elastically deform the first protrusion 211, so that the lock cylinder 121 rotates to the limiting space 213, the external force acting on the first protrusion 211 disappears, the elastic end 21 of the stopper 2 recovers to its original shape, and the lock cylinder 121 is located in the limiting space 213 all the time without the action of the external force, thereby locking the motor; since the distance from the second projection 212 to the axis of the motor shaft is small, the second projection 212 serves as a stopper for preventing the lock cylinder 121 from rotating clockwise out of the stopper space 213.

The specific unlocking process comprises the following steps: the rotating part 12 is rotated counterclockwise, the lock cylinder 121 extrudes the first protrusion 211 on the elastic end 21 to make it elastically deformed, the lock cylinder 121 is separated from the limit space 213, the external force acting on the first protrusion 211 disappears, the elastic end 21 of the stopper 2 recovers the original shape, and the unlocking of the motor is realized. The elastic motor lock in the scheme has the advantages of simple structure and relatively low manufacturing cost; since the distance from the second projection 212 to the axis of the motor shaft is small, the second projection 212 functions as a stopper for preventing the lock cylinder 121 from rotating counterclockwise into the stopper space 213. Both ends of the second protrusion 212 in this embodiment can be used as stopping portions to prevent the lock cylinder 121 from rotating clockwise to separate from the limiting space 213 and rotating counterclockwise to enter the limiting space 213; one part achieves the effect of two parts in the prior art, namely, the locking (limiting of the lock cylinder 121) effect is achieved, and the stopping (preventing the rotating part 12 and the fixing part 11 of the motor from rotating relative to each other by more than 360 degrees, and causing the wire inside the motor to wind) effect is achieved.

The above embodiment exemplarily shows the structure of the second protrusion 212 as the stopping portion, and according to other embodiments or practical applications, the second protrusion 212 may also be replaced by other structures, for example, as shown in fig. 5 to 6, the second protrusion 212 as the stopping portion is in a hook shape, after locking, the lock cylinder 121 rotates to the limiting space 213, the external force acting on the first protrusion 211 disappears, the elastic end 21 of the stopper 2 recovers to its original shape, and at this time, the hook-shaped second protrusion 212 hooks the lock cylinder 121, so that it cannot rotate clockwise to disengage from the limiting space 213; in the unlocked state, the second protrusion 212 needs to hook the lock cylinder 121, so that the lock cylinder 121 cannot rotate counterclockwise into the limiting space 213 or can rotate counterclockwise into the limiting space 213 only with a large external force, i.e., the lock cylinder has a stopping function.

The above embodiment exemplarily shows the second protrusion 212 as a stop, and the first protrusion 211 as a stop can also serve the same function and achieve the same effect according to other embodiments or practical applications.

The elastic motor lock in the above embodiment may also be used for other shaft motors of the photographing stabilizer, for example, a heading shaft motor, a pitching shaft motor, and the like of the stabilizer.

The utility model provides a pair of elastic motor lock and stabilizer, simple structure, spare part are less, manufacturing cost is lower relatively, only need a part, and two archs of locating part elasticity end 21 restrict lock post 121 clockwise and two anticlockwise rotation directions respectively under the effect of no external force promptly, need not change the structure and the thickness of motor.
