Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of control mechanisms, in particular to a rotary table and an optoelectronic device. BACKGROUND

[0002] In order to adjust the orientation of an optoelectronic element such as a camera, the optoelectronic element is usually mounted on an optoelectronic rotary table that can move.

[0003] The optoelectronic rotary table can move and can be kept in a certain posture in a powered state, but when powered off, the rotating part of the optoelectronic rotary table can rotate at will, which can affect the storage, turnover, handling, transportation, hoisting and other operations of the device. If there is an impact or scratching, it can affect the appearance and sales, or even cause damage and even risk of injury.

[0004] Therefore, it is desirable to limit the movement of the optoelectronic rotary table in a non-working state. SUMMARY

[0005] Therefore, it is necessary to provide a rotary table and an optoelectronic device to solve at least one of the above problems.

[0006] In one aspect, the present application provides a rotary table, which comprises: a first rotary seat; a second rotary seat rotationally connected to the first rotary seat and defining a first axial direction; and a first ratchet lock mechanism arranged on the second rotary seat, the first ratchet lock mechanism having an unlocked state allowing the second rotary seat to rotate and a locked state preventing the second rotary seat from rotating, the first ratchet lock mechanism having a push control surface capable of switching between the locked state and the unlocked state in response to pressure on the push control surface, and the push control surface of the first ratchet lock mechanism being recessed on an outer surface of the second rotary seat.

[0007] By arranging the first ratchet lock mechanism, the first rotary seat and the second rotary seat can be locked relative to each other when the rotary table is not in use, thereby avoiding relative rotation. When the rotary table is in use, it can be unlocked to ensure normal operation of the rotary table. The push control surface is recessed to avoid accidental touch, especially accidental touch during operation. In addition, the structure is compact. The rotary table of the present application is stable in state during storage, turnover, handling, transportation and hoisting, is safe to use, and is easy to switch between states.

[0008] In some embodiments, the first ratchet locking mechanism comprises a locking cylinder, a control member, a locking member and an elastic reset member. The locking cylinder is arranged on the second rotating seat. The control member is slidingly connected to the locking cylinder and has a pressing control surface. The locking member has a first rotating position and a second rotating position relative to the locking cylinder. The locking member in the first rotating position has a sliding stroke limited by the locking cylinder. The locking member in the second rotating position is limited by the locking cylinder at the end of the sliding stroke. The elastic reset member is arranged on the locking cylinder and is used to drive the locking member towards the control member. The locking member in the sliding stroke abuts against the control member and makes the first ratchet locking mechanism in an unlocked state. The control tooth disc of the control member is circumferentially misaligned with the ratchet tooth disc of the locking member. The ratchet tooth disc beyond the sliding stroke can rotate relative to the locking cylinder to change the rotating position, driven by the control member and the elastic reset member.

[0009] In this way, the first ratchet locking mechanism is compact in structure and easy to operate.

[0010] In some embodiments, the locking cylinder comprises a guide rail. The control member is provided with a first guide groove. The locking member is provided with a second guide groove. The first guide groove and the second guide groove are slidingly fitted in the guide rail. The end of the guide rail can abut against the ratchet tooth disc of the locking member in the second rotating position.

[0011] In this way, the synchronous sliding action of the control member and the locking member is smooth and easy to operate.

[0012] In some embodiments, the locking cylinder comprises a plurality of guide rails arranged circumferentially. The locking member is provided with a plurality of first guide grooves arranged circumferentially. Between any two adjacent first guide grooves, two ratchet teeth of the ratchet tooth disc are arranged. The control member is provided with a plurality of second guide grooves arranged circumferentially. Between any two adjacent second guide grooves, three control teeth of the control tooth disc are arranged.

[0013] In this way, the stress is balanced, and the state can be switched cyclically.

[0014] In some embodiments, the locking member comprises a flange plate. The elastic reset member abuts against the flange plate. The locking cylinder comprises a first cylinder body and a second cylinder body. The elastic reset member is arranged on the first cylinder body. The second cylinder body is arranged on the first cylinder body. The second cylinder body can abut against the flange plate of the locking member in the first rotating position.

[0015] In this way, the elastic reset member is easy to install. The stroke can be controlled, which helps to make the action responsive.

[0016] In some embodiments, the first rotating seat is provided with at least one locking hole. The first ratchet locking mechanism comprises a pin shaft that is controlled to reset and feed. The pin shaft of the first ratchet locking mechanism passes through the locking hole to prevent the second rotating seat from rotating relative to the first shaft based on the first axis.

[0017] In this way, the locking connection strength is improved, and the locked state is reliable.

[0018] In some embodiments, the turret further comprises a third turret and a second ratchet locking mechanism, the third turret is rotatably connected to the first turret or the second turret, the third turret defines a second axial direction, the second axial direction intersects the first axial direction; the second ratchet locking mechanism has an unlocked state allowing the third turret to rotate and a locked state preventing the third turret from rotating.

[0019] In this way, the turret has higher mechanism freedom degree, and can lock a posture when not working, and avoid free movement without power.

[0020] In some embodiments, the push control surface of the second ratchet locking mechanism is recessed on a surface of the turret; the first axial direction is perpendicular to the second axial direction, the push direction of the push control surface of the first ratchet locking mechanism is along the first axial direction, and the push direction of the push control surface of the second ratchet locking mechanism is along the second axial direction.

[0021] In this way, the second ratchet locking mechanism can also avoid being accidentally touched, and the possible collision interference problem during movement is also avoided.

[0022] For example, the second ratchet locking mechanism is arranged on one of the first turret and the second turret which connects the third turret, or is arranged on the third turret.

[0023] In some embodiments, the second turret comprises a rotating disc and two support arms, the support arms are fixed to the rotating disc, the rotating disc is rotatably connected to the first turret, and the third turret is located between the two support arms and is rotatably connected to the support arms.

[0024] In this way, the third turret can be supported away from the first turret, the movement space of each turret of the turret is large, and the movement amplitude or angle is large. The two support arms also help to stably support the third turret.

[0025] In another aspect, the application provides an optoelectronic device, comprising: an optoelectronic element; and the aforementioned turret, the optoelectronic element being arranged on the turret.

[0026] The optoelectronic device of the application can adjust the orientation of the optoelectronic element when working, and can be stopped in a non-working state. BRIEF DESCRIPTION OF DRAWINGS

[0047] Reference Figure 1 , Figure 1 The turret in the present application is shown, and for the convenience of description, a space rectangular coordinate system XYZ is established. The turret 100 can include at least two rotating seats and at least one ratchet locking mechanism 10. The rotating seats can be connected in turn, and the ratchet locking mechanism 10 is used to lock the two rotating seats that can rotate relative to each other and can also be unlocked. More ratchet locking mechanisms 10 can be matched with the two rotating seats in the turret 100 to achieve more reliable locking. The ratchet locking mechanism 10 can be used to limit the two rotating seats to a specific position, or one of multiple optional positions.

[0048] In an exemplary embodiment, the turret 100 includes a first rotating seat 110 and a second rotating seat 120, and the second rotating seat 120 is rotatably connected with the first rotating seat 110. In use, for example, the first rotating seat 110 can be fixed at a fixed position, and the second rotating seat 120 can rotate relative to the first rotating seat 110. The first axis defined by the second rotating seat 120 can be substantially parallel to the Z-axis direction, and the second rotating seat 120 can rotate 360° along the XY plane.

[0049] Reference Figure 1 The second rotating seat 120 is provided with a first ratchet locking mechanism 140, and the ratchet locking mechanism 10 is in an unlocked state, so that the second rotating seat 120 can rotate relative to the first rotating seat 110 based on the first axis. Reference Figure 2 When the first ratchet locking mechanism 140 is in a locked state, the second rotating seat 120 can be limited at a specific angular position of the first rotating seat 110, and the first ratchet locking mechanism 140 prevents the second rotating seat 120 from rotating.

[0050] Reference Figure 1 And Figure 3The first ratchet locking mechanism 140 has a pressing control surface 101, which is recessed into the outer surface 1201 of the second rotary table 120. When pressing is required, a specific tool can be inserted through a hole in the outer surface 1201 to trigger the pressing control surface 101. If the hole is large, it can also be pressed with a finger. The outer surface 1201 can be designed to be relatively flat and smooth, making it less likely to accidentally touch the first ratchet locking mechanism 140; furthermore, the rotary table 100 has a continuous, complete, and aesthetically pleasing appearance. Figure 4 As shown, the first ratchet locking mechanism 140 can switch between locked and unlocked states in response to pressure applied to the control surface 101.

[0051] Combination Figure 10 , Figure 11 and Figure 12 The turntable 100 also includes a third rotary seat 130 and a second ratchet locking mechanism 150. Exemplarily, the third rotary seat 130 is rotatably connected to the second rotary seat 120. The third rotary seat 130 is capable of two degrees of freedom of movement relative to the first rotary seat 110. The third rotary seat 130 defines a second axis that intersects the first axis, allowing the third rotary seat 130 to rotate to different positions in space relative to the first rotary seat 110. The second ratchet locking mechanism 150 may be disposed in the second rotary seat 120, and in other embodiments, may be disposed in the third rotary seat 130. The second ratchet locking mechanism 150 has an unlocked state that allows the third rotary seat 130 to rotate and a locked state that prevents the third rotary seat 130 from rotating. The turntable 100 may also have more rotary seats and more ratchet locking mechanisms 10, which can be used to lock two directly connected rotary seats. The turntable 100 has higher degrees of freedom of mechanism and can lock its posture when not in operation, preventing unpowered free movement.

[0052] The pressing control surface 101 of the second ratchet locking mechanism 150 can be referred to as the second pressing control surface. This pressing control surface 101 is also recessed in the surface of the turntable 100. When the second ratchet locking mechanism 150 is provided on the second rotary table 120, the pressing control surface 101 is recessed in the outer surface 1201. The second ratchet locking mechanism 150 can also prevent accidental activation and avoid possible collision interference problems during movement.

[0053] refer to Figure 1 In the turntable 100 with this orientation, the second axis defined by the third rotary table 130 can be parallel to the Y-axis direction. When the second rotary table 120 drives the third rotary table 130 to rotate along the XY plane, the second axis can be rotated to other positions. Exemplarily, the first axis is perpendicular to the second axis. The second rotary table 120 and the third rotary table 130 can be used to form a pitch assembly, and the third rotary table 130 can rotate 180° relative to the second rotary table 120, and can perform pitch movements within a range of ±90° based on the XY plane as a reference point.

[0054] When the turntable 100 is not used, the first ratchet locking mechanism 140 can lock the first rotating seat 110 and the second rotating seat 120 relative to each other to avoid relative rotation; the second ratchet locking mechanism 150 can lock the second rotating seat 120 and the third rotating seat 130 relative to each other to avoid relative rotation. When the turntable 100 is used, it can be unlocked to ensure normal operation of the turntable 100. Each push control surface 101 is recessed relative to the surface of the turntable 100, which can avoid accidental touch, especially accidental touch during action. The turntable 100 has a compact structure, and each rotating seat can be assembled and actuated with a relatively compact structure and a relatively close profile. The turntable 100 of the present application is stable in state and safe to use during storage, turnover, handling, transportation, hoisting and other operations; the state switching is convenient.

[0055] Exemplarily, the execution end of the first ratchet locking mechanism 140 can have a large friction force and directly adhere to the surface of the first rotating seat 110. The execution end of the ratchet locking mechanism 10 can be a sleeve, and the opposite rotating seat is provided with a fixing rod capable of penetrating into the sleeve. The execution end can have a tooth shape and engage with a face gear or bevel gear provided on the opposite rotating seat to achieve limiting and fixing.

[0056] Reference Figure 1 and Figure 2 The first rotating seat 110 can be provided with at least one lock hole 105. In combination with Figure 3 and Figure 4 shown, the first ratchet locking mechanism 140 includes a controlled reset pin 32, and the pin 32 of the first ratchet locking mechanism 140 is matched with the lock hole 105 to prevent the second rotating seat 120 from rotating relative to the first axis, which is beneficial to improve the locking connection strength and the reliability of the locking state.

[0057] In combination with Figures 3 to 9 , the ratchet locking mechanism 10 includes a lock cylinder 1, a control member 2, a locking member 3 and an elastic reset member 4. The structures of the first ratchet locking mechanism 140 and the second ratchet locking mechanism 150 can be basically the same.

[0058] The lock cylinder 1 is arranged on the rotating seat, for example, the lock cylinder 1 of the first ratchet locking mechanism 140 is arranged on the second rotating seat 120. Exemplarily, the lock cylinder 1 includes a first cylinder body 11 and a second cylinder body 12, and the two cylinder bodies are assembled together to limit other parts and enable other parts to be installed on the lock cylinder 1.

[0059] The control member 2 is slidingly connected to the lock cylinder 1, and the sliding direction can be along the Z-axis direction. The control member 2 has a push control surface 101. The control member 2 can include a control tooth disc 21 and a top rod 22. The control tooth disc 21 and the top rod 22 can be fixed, and at least relatively fixed along the Z-axis direction. The top rod 22 can have the push control surface 101. The top rod 22 has a sufficient use length and extends into the lock cylinder 1. The control tooth disc 21 can be limited in the lock cylinder 1 to prevent the control member 2 from being separated from the lock cylinder 1.

[0060] The lock member 3 has a first rotation position and a second rotation position relative to the lock cylinder 1. Referring to Figure 3 In the first step, the lock member 3 in the first rotation position has a sliding stroke limited by the lock cylinder 1. In the fourth step, the lock member 3 in the second rotation position is limited by the lock cylinder 1 at the end position of the sliding stroke. The lock member 3 includes a ratchet tooth disc 31 and a pin shaft 32. Exemplarily, the ratchet tooth disc 31 is rotationally connected to the pin shaft 32, and the rotation axis is along the push direction. When the ratchet tooth disc 31 rotates, the pin shaft 32 can not rotate. The pin shaft 32 only slides, has stable performance, small wear, and long service life. In other embodiments, the ratchet tooth disc 31 can be fixed to the pin shaft 32, and the pin shaft 32 can rotate relative to the lock cylinder 1 or the elastic return member 4.

[0061] The elastic return member 4 is arranged in the lock cylinder 1 and is used to drive the lock member 3 towards the control member 2. The elastic return member 4 cooperates with the control member 2 to control the lock member 3.

[0062] Referring to Figure 5 The lock member 3 includes a flange plate 33, which can be fixed to the pin shaft 32 at least in the axial direction. The elastic return member 4 can be a spring, which is then sleeved on the pin shaft 32. The elastic return member 4 abuts against the flange plate 33, which can then be pushed. Referring to Figure 9 and Figure 6 The elastic return member 4 can be arranged in the first cylinder body 11. The bottom flange plate of the first cylinder body 11 can be penetrated by the pin shaft 32, while limiting the lower end of the elastic return member 4. The second cylinder body 12 is arranged in the first cylinder body 11, for example, the two are threadedly connected. The second cylinder body 12 can be penetrated in the first cylinder body 11, and the lower end of the second cylinder body 12 can abut against the flange plate 33 of the lock member 3 in the first rotation position. The structure of the lock cylinder 1 is easy to install the elastic return member 4; the stroke of the lock member 3 can be controlled, which helps to make the action agile.

[0063] Based on the principle of ratchet mechanism, the locking piece 3 comprises a ratchet tooth disc 31, the control piece 2 can be regarded as a driving pawl, and the lock cylinder 1 is provided with a stop pawl. Exemplarily, the lock cylinder 1 can comprise a guide rail 102, which can be regarded as a stop pawl. The end 1021 of the guide rail 102 is capable of abutting against the ratchet tooth disc 31 of the locking piece 3 in the second rotational position. The control piece 2 and the locking piece 3 are respectively provided with guide grooves. The control piece 2 is provided with a first guide groove 103 which is slidingly fitted to the guide rail 102, and the locking piece 3 is provided with a second guide groove 104 which is slidingly fitted to the guide rail 102. The first guide groove 103 and the second guide groove 104 can be slidingly fitted to the same guide rail 102. The first guide groove 103 corresponds to the guide rail 102 when the locking piece 3 is in the first rotational position. The synchronous sliding action of the control piece 2 and the locking piece 3 is smooth, and the operation is easy.

[0064] In combination Figure 6 As shown, the lock cylinder 1 comprises a plurality of guide rails 102 arranged circumferentially. Specifically, it can be on the inner wall of the second cylinder body 12. Referring to Figure 8 and Figure 3 The locking piece 3 is provided with a plurality of first guide grooves 103 arranged circumferentially, and two ratchet teeth 310 of the ratchet tooth disc 31 are arranged between any two adjacent first guide grooves 103. Specifically, the ratchet tooth disc 31 is thicker than the pin shaft 32, so the first guide groove 103 can be formed in the ratchet tooth disc 31. Referring to Figure 7 The control piece 2 is provided with a plurality of second guide grooves 104 arranged circumferentially, and three control teeth 210 of the control tooth disc 21 are arranged between any two adjacent second guide grooves 104. Arranging a plurality of guide rails 102 is beneficial to balance the force of the locking piece 3 and enable it to switch states cyclically. In some cases, a plurality of guide rails 102 are also regarded as forming grooves, but based on the cyclic size of the ratchet tooth disc 31, the width of each guide rail 102 is smaller than the width of one ratchet tooth 310.

[0065] Referring to Figure 3 The structure in the first step is the ratchet locking mechanism 10 in the unlocked state, the locking piece 3 in the first rotational position also abuts against the control piece 2 in the sliding stroke, the top end of the jacking rod 22 is relatively high, i.e., the position of the pressing control surface 101, the pin shaft 32 is relatively shortened relative to the lock cylinder 1, and the control tooth disc 21 is circumferentially misaligned with the ratchet tooth disc 31. In Figure 3 the Z-axis direction in the top view, the control tooth disc 21 can comprise a first control tooth, a second control tooth and a third control tooth, and the ratchet tooth disc 31 can comprise a first ratchet tooth and a second ratchet tooth. At this time, the first control tooth and the second control tooth respectively abut against the first ratchet tooth and the second ratchet tooth without complete engagement, although there is a driving rotation component force between the control tooth disc 21 and the ratchet tooth disc 31, but it cannot rotate relatively due to the limitation of the lock cylinder 1.

[0066] Referring to the second step, the control member 2 can push the locking member 3 to move until the end 1021 of the ratchet tooth disc 31 is reached, at which time the locking cylinder 1 no longer restricts the rotation of the ratchet tooth disc 31. The first ratchet tooth is turned over the end 1021 under the pushing of the elastic return member 4 and the force of the ratchet tooth 310 and the control tooth 210.

[0067] Referring to the third step, the operator releases the push of the control surface 101, and the locking member 3 and the control member 2 are forced to rise under the action of the elastic return member 4. Exemplarily, the end 1021 is configured in a wedge-shaped structure. Therefore, during the rising process, the locking member 3 continues to rotate. The second ratchet tooth can cross the first control tooth, and the first ratchet tooth crosses the third control tooth in the previous group of control teeth 210.

[0068] Referring to the fourth step, the end 1021 can stop the ratchet tooth 310, and the locking member 3 can no longer rise, at which time the pin shaft 32 protrudes from the locking cylinder 1 to lock the two rotating seats corresponding to the ratchet locking mechanism 10. The ratchet tooth disc 31 beyond the sliding stroke is driven to rotate relative to the locking cylinder 1 by the control member 2 and the elastic return member 4, and is changed from the first rotating position to the second rotating position. The ratchet locking mechanism 10 is compact in structure and simple to operate.

[0069] In combination Figure 4 The structure in the first step is shown, that is, the ratchet locking mechanism 10 in the locked state, in which the ratchet tooth disc 31 and the locking member 3 are in the second rotating position. By pressing the control surface 101, the ratchet tooth disc 31 can be pressed down, so that the second ratchet tooth is disengaged from the circumferential limitation of the end 1021 and can rotate at least a distance, for example, the second ratchet tooth is limited by the third control tooth in the previous group.

[0070] Referring to the second step, the operator removes the pressure. Under the pushing of the elastic return member 4, the ratchet tooth disc 31 rotates relative to the end 1021 and the control member 2, and the control member 2 is forced to rise. The second ratchet tooth can cross the third control tooth.

[0071] Referring to the third step, the ratchet tooth disc 31 continues to rise and can rotate to the position where the first ratchet tooth is limited by the previous guide rail 102. At this time, the ratchet tooth disc 31 is considered to be in the first rotating position in the circular rotation. The second ratchet tooth has crossed the second control tooth.

[0072] Referring to the fourth step, the locking member 3 and the control member 2 continue to be pushed upward by the elastic return member 4, and stop rising when the flange plate 33 abuts against the second cylinder 12. The guide rail 102 can be longer than the sliding stroke of the control member 2. The pin shaft 32 is shortened relative to the locking cylinder 1. The ratchet locking mechanism 10 is in the unlocked state and can be used for the next locking.

[0073] Referring to Figure 1 , Figure 2 ,Figure 10 、 Figure 11 and Figure 12 The second rotating base 120 comprises a rotating disc 121 and two supporting arms 122 fixed to the rotating disc 121 and arranged oppositely along the Y-axis direction. The second rotating base 120 can further comprise two connecting arms 123. The connecting arms 123 and the rotating disc 121 can be in an integral structure. The supporting arms 122 can be detachably connected to the connecting arms 123. The rotating disc 121 is rotationally connected to the first rotating base 110. The third rotating base 130 is located between the two supporting arms 122 and rotationally connected to the supporting arms 122. The third rotating base 130 can be supported to move away from the first rotating base 110. The movable space of each rotating base of the rotating table 100 is large, and the movement range or angle is large. The two supporting arms 122 also help to stably support the third rotating base 130.

[0074] The setting position of the ratchet locking mechanism 10 can be set according to the operation needs.
