The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

An embodiment of the present invention provides a locking structure 10 of a motor, as shown in fig. 1, the locking structure 10 of the motor may be used in a pan/tilt head 100, and may also be used in other products, and is mainly used for preventing a rotor of the motor from freely rotating relative to a stator when the device is not in use.

As shown in fig. 2, the locking structure 10 of the motor includes a rotating device 1, a carrying device 2 and a locking assembly 3, wherein the rotating device 1 is rotatably connected to the carrying device 2. In this embodiment, the carrying device 2 may be a stator of an electric motor, and the rotating device 1 may be a rotor of the electric motor. In practice, the structure of the carrier 2 and the rotating device 1 may be determined according to the needs, for example, the carrier 2 may be a component fixed on the stator of the motor, and the rotating device 1 may be a component fixed on the rotor of the motor.

Generally, to protect the internal structure of the locking structure 10 of the motor, as shown in fig. 1, 3 and 4, the rotating device 1 includes a first housing 11, and correspondingly, the carrying device 2 includes a second housing 21, wherein the second housing 21 is abutted with the first housing 11 to form a protective shell (not shown) together, and the protective shell has a containing cavity 4 therein. It is understood that the locking structure 10 of the motor has a protective case integrally to protect the internal structure. Specifically, in this embodiment, the protective shell is composed of two parts, namely, the first shell 11 and the second shell 21, and actually, in other embodiments, the protective shell may also be composed of the first shell 11 or the second shell 21 alone, which is not limited herein.

It should be noted that, in the embodiment, as shown in fig. 1, fig. 3 and fig. 4, the first housing 11 and the second housing 21 are disposed at an axial gap of the motor, that is, the first housing 11 and the second housing 21 are not tightly covered, so as to conveniently check whether the locking assembly 3 completes the locking action, thereby ensuring the reliability of the locking of the device.

In the present embodiment, in order to prevent the rotating device 1 from rotating arbitrarily relative to the carrying device 2, as shown in fig. 2 to 4, the locking assembly 3 includes a locking button 31, a fixing seat 32 and at least one positioning portion 33, wherein the locking button 31 can slide in a damping manner relative to the fixing seat 32 in an axial direction of the motor. Specifically, the locking button 31 includes a base 311, correspondingly, the fixing base 32 includes an elastic portion 321, the base 311, the fixing base 32 and each positioning portion 33 are located in the accommodating cavity 4, and the protective shell is provided with a sliding hole 5 communicating with the accommodating cavity 4 for facilitating the operation of the locking button 31.

More specifically, at the position corresponding to the slide hole 5, the locking button 31 is in damped sliding connection with the fixed seat 32 in the axial direction of the motor through the concave-convex fit between the base 311 and the elastic part 321, so that the base 311 is in concave-convex fit with the positioning part 33 in the axial direction of the motor to lock the rotation of the motor, or the base 311 is disengaged from the positioning part 33 to unlock the motor.

It will be understood that the base 311 of the locking knob 31 is located in a sliding position in the accommodating cavity 4, so that the base 311 of the locking knob 31 can be easily operated or viewed through the sliding hole 5 to slide along the axial direction of the motor. In addition, the damping sliding connection between the locking button 31 and the fixed seat 32 can be realized by the concave-convex fit between the base 311 of the locking button 31 and the elastic part 321 of the fixed seat 32 (specifically, the side of the base 311 facing the elastic part 321 is concave-convex fit with the side of the elastic part 321 facing the base 311), and when the locking button 31 slides along the axial direction of the motor, the base 311 can synchronously move (such as move up or down) along the axial direction of the motor.

Thus, during the movement (e.g. downward movement) of the base 311, the base 311 can be in concave-convex fit with one of the positioning parts 33, so that the locking button 31 can be stationary relative to the positioning part 33, i.e. the locking button 31 is locked with the positioning part 33, so as to stop the rotation of the rotating device 1, thereby realizing the locking of the rotation of the motor; conversely, after the rotation of the motor is locked, the motor may be unlocked by moving (e.g., moving down) the base portion 311 to move the base portion 311 away from the positioning portion 33 in the axial direction of the motor to release the concave-convex engagement between the base portion 311 and the positioning portion 33, and restoring the rotation capability of the rotating device 1.

In short, the locking or unlocking of the rotation of the motor can be realized by moving the locking knob 31 in the axial direction of the motor to adjust the axial position of the base 311, and making the base 311 engage with the positioning part 33 in a concave-convex manner, or away from the positioning part 33 to release the concave-convex engagement.

It will also be understood that the locking knob 31 and the holder 32 are both arranged in the axial direction of the motor. Because the base portion 311 and the elastic portion 321 are in concave-convex fit, in the sliding process of the locking button 31, the elastic portion 321 can be extruded through the base portion 311, so that the elastic portion 321 is deformed, the axial sliding of the locking button 31 is realized, and a certain damping force is ensured in the sliding process, namely, the locking button 31 can slide only under the action of external force, so that the controllability of locking or unlocking of the motor is ensured, and the improvement of the overall reliability and safety is facilitated.

It is also understood that, since at least one positioning portion 33 is provided, when one positioning portion 33 is provided, the motor can be locked after rotating 360 degrees; similarly, when at least two positioning portions 33 are provided and each positioning portion 33 is circumferentially arranged around the center of the motor, the motor can rotate within a specified angle range. That is, the specific number of the positioning parts 33 may be determined according to actual needs.

It should be noted that, in order to realize the concave-convex fit between the base 311 and the positioning portion 33, in this embodiment, the positioning portion 33 is configured by a gear structure, and correspondingly, at an end close to the positioning portion 33, a slot 3115 is formed on a side wall of the base 311 away from the elastic portion 321, so as to form a gear structure on the base 311, which is adapted to the gear structure of the positioning portion 33. Of course, in practice, a corresponding gear structure may also be directly provided at the end of the base 311 close to the positioning portion 33, or a limiting groove may also be directly provided at the end of the base 311 close to the positioning portion 33, or a side wall of the end away from the elastic portion 321, and correspondingly, the structure of the positioning portion 33 may be a limiting protrusion, or the like.

In summary, compared with the prior art, the locking structure 10 of the motor has at least the following beneficial effects: in the locking structure 10 of the motor, the locking button 31 is connected to the fixed seat 32 in a damping sliding manner along the axial direction of the motor through the concave-convex fit between the base 311 of the locking button 31 and the elastic part 321 of the fixed seat 32, and after the motor rotates for a predetermined angle, the base 311 can be matched with the positioning part 33 in the axial direction of the motor through the sliding of the locking button 31 to limit the circumferential rotation of the rotating device 1, so that the rotating device 1 stops rotating, and the rotation of the motor is locked; when the motor needs to enter the working state, the base 311 can be separated from the positioning part 33 along the axial direction of the motor by sliding the locking button 31, so as to restore the circumferential rotation of the rotating device 1, thereby unlocking the rotation of the motor.

In short, the locking structure 10 of the motor ensures the damping sliding connection between the locking button 31 and the fixed seat 32 through the concave-convex fit between the base 311 and the elastic part 321, and simultaneously, the locking or unlocking of the rotation of the motor can be realized by combining the axial concave-convex fit between the base 311 and the positioning part 33.

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of some embodiments of the present invention will be clearly and completely described below with reference to fig. 2 to 8.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2 to fig. 4, in order to lock or unlock the rotation of the motor through the concave-convex matching relationship between the base 311 of the locking button 31 and the positioning portion 33 during the process of damping the sliding of the base 311 relative to the elastic portion 321 of the fixing seat 32, the positioning portion 33 of the locking assembly 3 is disposed on the inner wall of the second housing 21 along the circumferential direction of the second housing 21 of the carrying device 2. That is, the positioning portion 33 is provided around the rotation shaft of the motor. In addition, the fixing seat 32 is disposed on the rotating device 1.

Thus, when the base 311 moves axially (specifically, moves downwards) along the elastic portion 321 in the accommodating cavity 4 and is in concave-convex fit with the positioning portion 33, the base 311 is circumferentially restricted and cannot rotate, so that the fixing seat 32 in concave-convex fit with the base 311 stops rotating, and the rotating device 1 can be prevented from rotating by the fixing seat 32. Conversely, once the concave-convex matching relationship between the base 311 and the positioning part 33 is released, the base 311 can rotate along with the fixing seat 32 along with the rotating device 1.

Further, as a specific implementation manner in some embodiments of the present invention, in order to achieve the damping sliding connection between the base 311 of the locking button 31 and the elastic portion 321 of the fixing seat 32, as shown in fig. 3 to 5, a first anti-slip surface 3111 and a second anti-slip surface 3112 are disposed on a side (i.e. an inner side) of the base 311 close to the elastic portion 321, and a first step 3113 is formed between the first anti-slip surface 3111 and the second anti-slip surface 3112. Correspondingly, as shown in fig. 3, 4 and 7, a third anti-slip surface 3211 and a fourth anti-slip surface 3212 are provided on a side of the elastic portion 321 facing the base portion 311, and a second step 3213 is formed between the third anti-slip surface 3211 and the fourth anti-slip surface 3212.

As shown in fig. 3, when the base 311 is in concave-convex fit with the positioning portion 33, the first step 3113 is in concave-convex fit with the second step 3213 to prevent the locking button 31 from automatically moving (specifically, moving upwards) without external force, so that the base 311 is separated from the positioning portion 33, and the motor is ensured to be kept in a locked state. In other words, the first step 3113 and the second step 3213 are engaged with each other in a concave-convex manner, so that the lock knob 31 can be always engaged with the positioning portion 33.

Specifically, in the present embodiment, as shown in fig. 3 and 4, the notch of the first step 3113 is away from the positioning portion 33, and the notch of the second step 3213 is toward the positioning portion 33.

As shown in fig. 3 to 5, in order to keep the motor in the locked state all the time without being affected by external force, a notch 3116 is formed on a side of the base 311 facing the elastic portion 321, wherein the notch 3116 and the first anti-slip surface 3111 are respectively located on both sides of the second anti-slip surface 3112. In this way, the base 311 may further form a step structure on the side of the first step 3113 close to the positioning portion 33, and when the first step 3113 is in concave-convex fit with the second step 3213, the step structure may support the locking knob 31 through the components in the protective housing, so as to ensure that the locking knob 31 locks the rotation of the motor at the predetermined position.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 4, when the base 311 and the positioning portion 33 are disengaged from each other, the first step 3113 and the second step 3213 are also disengaged from each other, and at this time, the locking button 31 can keep the motor in the unlocked state through the contact between the second anti-slip surface 3112 and the third anti-slip surface 3211.

Specifically, in the present embodiment, in order to achieve this effect, further simplify the structure of the locking structure 10 of the motor, and ensure that the base portion 311 can perform damping sliding more smoothly with respect to the elastic portion 321, as shown in fig. 3, 4, and 7, the third sliding prevention surface 3211 is an inclined surface inclined from the elastic portion 321 toward the base portion 311.

In order to improve the stability and reliability of the concave-convex engagement between the base portion 311 and the elastic portion 321, the fourth anti-slip surface 3212 is also an inclined surface inclined from the elastic portion 321 toward the base portion 311. Preferably, the third and fourth

anti-slip surfaces

3211 and 3212 have the same inclination. Correspondingly, in order to make the base portion 311 and the elastic portion 321 closely fit to each other and further increase the damping force when the base portion 311 slides, as shown in fig. 3 to 5, the first anti-slip surface 3111 and the second anti-slip surface 3112 are both inclined surfaces inclined from the elastic portion 321 to the base portion 311, and the inclination of both surfaces is consistent with the inclination of the third anti-slip surface 3211.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 3 to fig. 5, a third step 3114 is further formed on a side of the base 311 close to the elastic portion 321, and the third step 3114 is located at an end of the second anti-slip surface 3112 close to the positioning portion 33, specifically, in this embodiment, the third step 3114 is located between the second anti-slip surface 3112 and the notch 3116. Correspondingly, as shown in fig. 3, 4 and 7, a fourth step 3214 is further formed on one end of the fourth anti-slip surface 3212, which is far from the third anti-slip surface 3211, on a side of the elastic portion 321, which is close to the base 311.

Specifically, as shown in fig. 3, when the motor is in the locked state, the third step 3114 is spaced from the fourth step 3214 in the axial direction of the motor; as shown in fig. 4, when the motor is in the unlocked state, the third step 3114 is engaged with the fourth step 3214 in a concave-convex manner. In this way, during the movement of the base 311, once the third step 3114 contacts the fourth step 3214, the lock knob 31 completes the maximum movement distance, ensuring that the lock knob 31 completely disengages from the positioning portion 33, and ensuring that the second anti-slip surface 3112 sufficiently contacts the third anti-slip surface 3211 to provide the maximum damping force for the lock knob 31 when sliding down.

It should be noted that, in the embodiment, in order to enable the locking button 31 to be smoothly and slidably connected to the elastic portion 321 of the fixing base 32, a groove 313 is formed on a side of the locking button 31 facing the elastic portion 321, so that when the locking button 31 slides and presses the third anti-sliding surface 3211 and the fourth anti-sliding surface 3212 (which may be both inclined surfaces) of the base, a certain elastic deformation space may be provided for the elastic portion 321.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 7, the fixing base 32 further includes an axial limiting portion 322, wherein one end of the limiting portion 322 is connected to the elastic portion 321, and a strip-shaped deformation gap 323 exists between the other end of the limiting portion and the elastic portion 321. Thus, by providing the deformation gap 323, the deformation space of the elastic portion 321 can be further enlarged, and the smoothness of the damping sliding between the lock knob 31 and the fixing base 32 can be further ensured.

As shown in fig. 7, a limiting space 324 is defined between the limiting portion 322 and the elastic portion 321, wherein the limiting space 324 is used for the base portion 311 to slide. In other words, the base 311 is disposed in the space 324 and slides within the area defined by the space 324. Thus, the moving space of the base 311 is limited by the limiting space 324, which is beneficial to ensure that the locking button 31 can stably and reliably damp and slide relative to the fixed seat 32.

Specifically, in the present embodiment, as shown in fig. 8, in order to simplify the structure of the locking structure 10 of the motor, the slide hole 5 is opened in the first housing 11. In order to fix the fixing base 32 on the rotating device 1, as shown in fig. 8, a strip-shaped limiting member 111 is protruded in the first housing 11 at a position corresponding to the sliding hole 5, wherein the limiting portion 322 of the fixing base 32 is fastened on the strip-shaped limiting member 111, and forms a cavity for limiting the movement of the base 311 together with the strip-shaped limiting member 111 and the first housing 11.

Further, as a specific implementation manner in some embodiments of the present invention, in order to further ensure the positioning and installation of the fixing base 32, as shown in fig. 8, a positioning column 113 is further disposed in the first housing 11 in a protruding manner, and correspondingly, as shown in fig. 7, the fixing base 32 further includes a connecting portion 325, wherein the connecting portion 325 is connected to a side of the elastic portion 321 away from the locking button 31, and a connecting hole 3251 is formed in the connecting portion 325. As shown in fig. 3, 4, 7 and 8, the positioning post 113 is inserted into the connecting hole 3251.

Specifically, in the present embodiment, the connecting portion 325 and the limiting portion 322 are disposed with a gap therebetween, so as to further improve the deformation capability of the elastic portion 321. In addition, to simplify the overall structure and facilitate installation, the connection portion 325, the stopper portion 322, and the elastic portion 321 are integrally formed. To improve the stability and reliability of the overall structure, the locking button 31 and the fixing seat 32 may be both made of hardware. Of course, other suitable materials may be used.
