[0043] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4In one embodiment of the present application, a locking device 10 is provided, comprising a first body 100, a second body 200, and a locking mechanism 300. The first body 100 can be used to clamp a mobile phone camera, the second body 200 and the first body 100 can rotate relative to each other, and the locking mechanism 300 is disposed on the second body 200. The first body 100 can be a mover, having a limiting slot 110 defined therein, and the second body 200 can be a stator.
[0044] See Figure 5 、 Figure 6 and Figure 7 The locking device 10 includes a sliding unit 310, a locking unit 320, and a first elastic unit 330. The sliding unit 310 is slidably connected to the second body 200 along a first direction, allowing the sliding unit 310 to move linearly between a locked position 12 and an unlocked position 11. The first elastic unit 330 abuts between the locking unit 320 and the second body 200. The locking unit 320 is disposed on the sliding unit 310. When the sliding unit 310 is in the unlocked position 11, the locking unit 320 disengages from the limiting groove 110, allowing the first body 100 and the second body 200 to rotate relative to each other. When the sliding unit 310 disengages from the unlocked position 11 and moves to the locked position 12, the first elastic unit 330 pushes the locking unit 320 in a second direction until it engages with the limiting groove 110, preventing the first body 100 and the second body 200 from rotating relative to each other. The second direction is arranged at an angle to the first direction; for example, the second direction and the first direction may be perpendicular to each other. In other embodiments, the first body 100 may be a stator, and the second body 200 may be a mover.
[0045] In some embodiments, the rotation axis about which the first body 100 and the second body 200 rotate relative to each other extends along the second direction. The first elastic unit 330 may be a spring, etc., and the elastic force direction of the first elastic unit 330 is the same as the second direction. The second body 200 is provided with a sliding cavity 210 and an elongated hole 220. For example, the elongated hole 220 may be a runway-shaped hole, etc. The sliding cavity 210 and the elongated hole 220 are interconnected. The sliding unit 310 includes a sliding member 311 and a toggle member 312. The sliding member 311 and the toggle member 312 are fixedly connected to each other. The toggle member 312 is protruding from the sliding member 311. The sliding member 311 and the sliding cavity 210 slide in cooperation along the first direction, and the toggle member 312 and the elongated hole 220 slide in cooperation along the first direction. The toggle member 312 includes a toggle head 3121, the cross-sectional dimension of which is larger than the width of the elongated hole 220, so that the toggle head 3121 is located outside the sliding cavity 210 and the elongated hole 220, so that the user can contact the toggle head 3121 to drive the entire sliding unit 310 to slide relative to the sliding cavity 210.
[0046] See Figure 4 、 Figure 9 and Figure 10 In some embodiments, the sliding unit 310 is provided with a receiving groove 3111 extending along a first direction. For example, the receiving groove 3111 can be provided on the sliding member 311 of the sliding unit 310. The locking unit 320 includes a locking member 321 and an abutting member 322 connected to each other. The abutting member 322 can be protrudingly provided on the locking member 321. The locking member 321 is movably provided in the receiving groove 3111. The receiving groove 3111 can effectively limit the locking member 321. When the sliding unit 310 is in the locked position 12, the locking member 321 is engaged with the limiting groove 110. When the sliding unit 310 is in the unlocked position 11, the locking member 321 is disengaged from the limiting groove 110, releasing the engagement therebetween. The first elastic unit 330 abuts between the locking member 321 and the second body 200.
[0047] See Figure 5 and Figure 6 In some embodiments, the second body 200 is provided with a sliding hole 230 extending in the second direction. The sliding hole 230 communicates with the sliding cavity 210, and the locking member 321 of the locking unit 320 slidably engages with the sliding hole 230. The locking member 321 engages with the sliding hole 230, so the sliding hole 230 effectively limits the movement of the locking member 321, ensuring that the locking member 321 can only move linearly relative to the sliding hole 230 and the second body 200 in the second direction.
[0048] See Figure 8 、 Figure 9 、 Figure 11 and Figure 12In some embodiments, the sliding unit 310 is provided with a guide hole 3112. The guide hole 3112 can be a blind hole or a through hole. The guide hole 3112 can be formed by a recess in the side wall of the receiving groove 3111, that is, the guide hole 3112 is provided on the side wall of the receiving groove 3111. The inner wall surface of the guide hole 3112 includes a first abutting surface 3113, a second abutting surface 3114, and an intermediate inclined surface 3115. The first abutting surface 3113, the second abutting surface 3114, and the intermediate inclined surface 3115 can all abut against the abutting member 322 of the locking unit 320. The first abutting surface 3113, the second abutting surface 3114, and the intermediate inclined surface 3115 can all be flat surfaces. The first abutting surface 3113 is closer to the first body 100 than the second abutting surface 3114. Both the first abutting surface 3113 and the second abutting surface 3114 extend along the first direction, allowing them to be parallel to each other. The intermediate inclined surface 3115 is connected between the first abutting surface 3113 and the second abutting surface 3114, such that the intermediate inclined surface 3115 is arranged at an angle to the first direction. This can be understood as the intermediate inclined surface 3115 being arranged at an angle relative to the first direction. When the sliding unit 310 moves toward the unlocked position 11, the abutting member 322 moves from the intermediate inclined surface 3115 toward the second abutting surface 3114. When the sliding unit 310 moves toward the locked position 12, the abutting member 322 moves from the intermediate inclined surface 3115 toward the first abutting surface 3113. For example, when the sliding unit 310 is in the unlocked position 11, the abutting member 322 abuts against the second abutting surface 3114; when the sliding unit 310 is in the locked position 12, the abutting member 322 abuts against the first abutting surface 3113. Since the intermediate inclined surface 3115 is inclined relative to the first direction, and the locking member 321 can only move linearly along the second direction relative to the sliding hole 230 and the second body 200, when the abutting member 322 moves on the intermediate inclined surface 3115 toward the first abutting surface 3113, the locking member 321 will gradually approach the limiting groove 110 under the elastic force generated by the first elastic unit 330. When the abutting member 322 moves on the intermediate inclined surface 3115 toward the second abutting surface 3114, the intermediate inclined surface 3115 will generate a thrust on the abutting member 322 and the locking member 321, thereby causing the locking member 321 to gradually move away from the limiting groove 110.
[0049] In some embodiments, the abutment member 322 can be rotatably connected to the locking member 321, and the abutment member 322 can rotate relative to the locking member 321 around a rotation axis extending perpendicular to both the first direction and the second direction. The rotatable connection between the abutment member 322 and the locking member 321 can form roller friction between the abutment member 322 and the first abutment surface 3113, the second abutment surface 3114, and the intermediate inclined surface 3115, thereby reducing the frictional resistance generated by the abutment member 322 and the entire locking unit 320 during movement relative to the sliding unit 310, thereby reducing the blocking phenomenon of the locking unit 320 and improving the smoothness of the movement of the locking unit 320.
[0050] See Figure 6 and Figure 7 When a user applies force to the toggle head 3121 in the unlocked position 11 to push the slider 311 in the first direction from the unlocked position 11 to the locked position 12, the first elastic unit 330 releases energy, causing the first elastic unit 330 to push the entire locking unit 320 in the second direction via the locking member 321. When the locking member 321 extends into the limiting groove 110 and engages with the limiting groove 110, the locking member 321 will limit the first body 100 along its circumferential direction, effectively preventing the first body 100 from rotating relative to the second body 200. When a user applies force to the toggle head 3121 in the locked position 12 to push the sliding member 311 along the first direction from the locked position 12 to the unlocked position 11, the sliding member 311 can generate a thrust on the abutting member 322 via the intermediate inclined surface 3115, thereby causing the abutting member 322 to drive the locking member 321 to gradually move away from the limiting groove 110 in the second direction. The locking member 321 compresses the first elastic unit 330, causing the first elastic unit 330 to store energy. That is, the sliding member 311 overcomes the elastic force of the first elastic unit 330 to drive the locking member 320 to gradually move away from the limiting groove 110. When the sliding member 310 moves to the unlocked position 11, the locking member 321 completely disengages from the limiting groove 110, thereby releasing the locking member 321 from limiting the first body 100 along the circumferential direction of the second body 200, ensuring that the first body 100 can rotate relative to the second body 200.
[0051] See Figure 8In some embodiments, the locking mechanism 300 further includes a second elastic unit 340, and the elastic forces generated by the second elastic unit 340 and the first elastic unit 330 are perpendicular to each other. One of the sliding unit 310 and the second body 200 is provided with the second elastic unit 340, and the other is provided with a positioning cavity 3116. For example, the positioning cavity 3116 can be provided on the sliding member 311 of the sliding unit 310, while the second elastic unit 340 is fixedly provided on the second body 200. For another example, the positioning cavity 3116 can be provided on the second body 200, while the second elastic unit 340 is fixedly provided on the sliding member 311 of the sliding unit 310.
[0052] In the unlocked position 11, the second elastic unit 340 cooperates with the positioning cavity 3116. The cooperation and frictional resistance between the second elastic unit 340 and the positioning cavity 3116 effectively fix the sliding unit 310 in the unlocked position 11, effectively preventing the sliding unit 310 from disengaging from the unlocked position 11. Of course, when a user applies force to the toggle head 3121, the force on the toggle head 3121 effectively overcomes the cooperation and frictional resistance between the second elastic unit 340 and the positioning cavity 3116, thereby disengaging the second elastic unit 340 from the positioning cavity 3116, thereby allowing the sliding unit 310 to move from the unlocked position 11 to the locked position 12. After the user applies force to the toggle head 3121 to disengage the second elastic unit 340 from the positioning cavity 3116, the user can continue to apply force to the toggle head 3121 to move the sliding unit 310 to the locked position 12, thereby allowing the locking member 321 to cooperate with the limiting groove 110.
[0053] See Figure 6 、 Figure 7 and Figure 9It can be understood that, given the action of the intermediate inclined surface 3115, as the abutting member 322 moves relative to the intermediate inclined surface 3115 toward the first abutting surface 3113, under the action of the first elastic unit 330, the abutting member 322 will generate a force component directed in the first direction toward the locking position 12 on the intermediate inclined surface 3115 and the entire sliding member 311. This force component will push the sliding member 311 toward the locking position 12. Therefore, if this force component is greater than the frictional resistance generated during the movement of the sliding member 311, this force component can automatically drive the sliding member 311 toward the locking position 12. Therefore, after the user applies a force to the toggle head 3121 to disengage the second elastic unit 340 from the positioning cavity 3116, the force applied to the toggle head 3121 can be removed, and the elastic force generated by the first elastic unit 330 will automatically push the sliding member 311 to the locking position 12. In other words, during the movement of the sliding unit 310 from the unlocked position 11 to the locked position 12, it is only necessary to apply force to the toggle head 3121 at the initial moment. After the second elastic unit 340 is disengaged from the positioning cavity 3116, there is no need to continue applying force to the toggle head 3121. The sliding unit 310 can be effectively pushed from the unlocked position 11 to the locked position 12 only by the elastic force of the first elastic unit 330.
[0054] During the process of moving the sliding unit 310 from the locked position 12 to the unlocked position 11, since the elastic force of the first elastic unit 330 needs to be overcome, it is necessary to continuously apply force to the toggle head 3121 until the second elastic unit 340 engages with the positioning cavity 3116, and the sliding unit 310 reaches the unlocked position 11. Since the second elastic unit 340 engages with the positioning cavity 3116, the sliding unit 310 can be effectively fixed in the unlocked position 11.
[0055] See Figure 8 In some embodiments, the second elastic unit 340 can be a sheet-shaped spring, which is fixedly connected to the second body 200 and can be received in the receiving groove 3111 of the sliding member 311. The spring is provided with a protrusion 341, which cooperates with the positioning cavity 3116. When the sliding member 311 moves to the unlocked position 11, the protrusion 341 will correspond with the positioning cavity 3116. Under the action of the elastic force of the second elastic unit 340, the protrusion 341 and the positioning cavity 3116 cooperate with each other. When a certain force is applied to the sliding member 311 by the toggle head 3121, the protrusion 341 can overcome the elastic force of the second elastic unit 340 and disengage from the positioning cavity 3116, thereby allowing the sliding unit 310 to move from the unlocked position 11 to the locked position 12.
[0056] The working principle of the locking device 10 is described below:
[0057] When the sliding unit 310 is in the locked position 12 and it is desired to enable relative rotation between the first body 100 and the second body 200, the user can apply a force to the toggle head 3121, causing the sliding unit 310 to overcome the elastic force of the first elastic unit 330 through the intermediate inclined surface 3115 and apply a force to the abutment member 322 and the entire locking unit 320, causing the first elastic unit 330 to store energy. By continuously applying the force to the toggle head 3121, when the sliding unit 310 moves in the first direction to the unlocked position 11, the second elastic unit 340 will engage with the positioning cavity 3116. At this point, the force applied to the toggle head 3121 can be removed, and the second elastic unit 340 will act to keep the sliding unit 310 in the unlocked position 11. Obviously, when the sliding unit 310 stays in the unlocking position 11, the locking member 321 of the locking unit 320 will disengage from the limiting groove 110, thereby releasing the circumferential limiting effect of the locking member 321 on the first body 100, so that the first body 100 can rotate relative to the second body 200.
[0058] When the sliding unit 310 is in the unlocked position 11 and it is desired to stop relative rotation between the first body 100 and the second body 200, the user can apply force to the toggle head 3121, causing the second elastic unit 340 to disengage from the positioning cavity 3116, thereby releasing the engagement between the second elastic unit 340 and the positioning cavity 3116. The first elastic unit 330 releases energy. Under the action of the elastic force generated by the first elastic unit 330, the intermediate inclined surface 3115 removes the force applied to the toggle head 3121, allowing the sliding unit 310 to move toward the locked position 12 solely through the elastic force generated by the first elastic unit 330. When the sliding unit 310 moves to the locked position 12, the locking member 321 engages with the limiting groove 110, circumferentially limiting the first body 100, thereby effectively preventing relative rotation of the first body 100 relative to the second body 200.
[0059] In some embodiments, there are multiple limiting grooves 110, and the multiple limiting grooves 110 are arranged at intervals along the circumference of the first body 100. Given that there are multiple limiting grooves 110, the first body 100 can be locked in a preset position. It can be understood that when the sliding unit 310 moves toward the locking position 12, when the locking member 321 abuts against the first body 100 but is not aligned with the limiting groove 110 in the second direction, the first body 100 can be slowly rotated relative to the second body 200 by a certain angle. At the moment when the locking member 321 and the limiting groove 110 are aligned, the locking member 321 will produce a "stepping-in-the-air" effect and quickly and effectively cooperate with the limiting groove 110.
[0060] Therefore, since the sliding unit 310 is slidably connected to the second body 200 along the first direction between the locked position 12 and the unlocked position 11, when the sliding unit 310 is in the unlocked position 11, the locking unit 320 disengages the limiting groove 110, allowing relative rotation between the first body 100 and the second body 200; when the sliding unit 310 disengages the unlocked position 11 and moves to the locked position 12, the first elastic unit 330 pushes the locking unit 320 along the second direction until it engages with the limiting groove 110, preventing relative rotation between the first body 100 and the second body 200. Therefore, the number of components of the locking mechanism 300 is reduced, making the locking mechanism 300 simple in structure and compact in size. This can simplify the structure of the entire locking device 10 and also achieve a miniaturized and lightweight design of the locking device 10.
[0061] In some embodiments, the present application further provides a gimbal, which includes the locking device 10. Since the gimbal includes the locking device 10, the structure of the gimbal can be simplified, thereby achieving a miniaturized and lightweight design of the gimbal.
[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0063] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
