Description

TECHNICAL FIELD

[0001] The present application relates to the field of spotlight technology, in particular to an automatic telescopic multi-angle lighting spotlight. BACKGROUND

[0002] As a directional lighting device, the spotlight is widely used in commercial display, indoor decoration, stage performance, industrial inspection and other fields due to its strong spotlighting, high brightness and precise pointing. With the continuous expansion of application scenarios, users have higher and higher requirements for the lighting flexibility, adjustment convenience and adaptability of the spotlight. The existing spotlight products gradually expose many deficiencies and are difficult to meet the diversified use requirements.

[0003] At present, the spotlights on the market are mainly divided into fixed type and adjustable type. The fixed type spotlight cannot adjust the lighting angle and height after installation, and has poor adaptability. When the lighting area needs to be changed, it must be disassembled and reinstalled, which is tedious and inefficient. Although the adjustable type spotlight can realize certain angle adjustment, it mostly adopts manual adjustment mode and needs to be operated close to the person. For the spotlight installed at a high place or the area not easy to reach (such as the deep part of the ceiling), the adjustment is extremely difficult.

[0004] In addition, most products can only realize single-dimensional adjustment and cannot realize multi-angle and omnidirectional lighting coverage, which is difficult to meet the directional lighting requirements in complex scenes. SUMMARY

[0005] The present application aims to at least solve one of the problems existing in the prior art to some extent. To this end, the present application provides an automatic telescopic spotlight which is compact in structure, convenient to adjust and can realize multi-dimensional collaborative adjustment.

[0010] In some embodiments, the clutch switching mechanism includes a transmission shaft rotatably mounted on two support plates, a second bevel gear meshing with the first bevel gear at the inner end of each of the two transmission shafts, a rotating column at the outer end of each of the two transmission shafts, a rotating collar at the lower end of the rotating shell and located outside the two support plates, a rotating disk rotatably mounted in each of the two rotating collars, the rotating column and the rotating disk being elastically connected by an elastic connecting component, and a guide limiting mechanism between the rotating collar and the rotating disk for limiting the rotation of the rotating disk, one of the two rotating disks being connected to the rotary transmission mechanism and the other being connected to the swing transmission mechanism.

[0011] In some embodiments, the elastic connection assembly includes a plurality of circular slots evenly distributed along the circumference at the outer end of the rotating column, a spring and a positioning steel ball are disposed in the circular slots, and a plurality of positioning grooves that cooperate with the positioning steel balls are evenly distributed along the circumference at the inner end of the rotating disk.

[0012] In some embodiments, the guide limiting mechanism includes a ratchet disposed at the outer end of the rotating disk, and an elastic pawl that cooperates with the ratchet is also disposed on the outer side of the rotating collar. The outer end of the ratchet is also disposed with an eccentric column that is connected to the rotary transmission mechanism or the swing transmission mechanism.

[0013] In some embodiments, a cavity is provided at the lower end of the lifting column, and the rotary transmission mechanism includes an annular bevel gear disposed on the inner wall of the cavity. A boss is provided at the upper end of the rotating shell, and a third bevel gear and a first gear are rotatably mounted on one side of the boss. The third bevel gear meshes with the annular bevel gear. A movable rod moves up and down inside the rotating shell. A first rack that meshes with the first gear is provided at the upper end of the movable rod, and a transverse slide groove is provided at the lower end of the movable rod.

[0032] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0033] like Figures 1-11 An automatic telescopic multi-angle spotlight is shown, comprising a sleeve housing 1, a lifting column 2 that is movably telescopically attached to the sleeve housing 1 along its axial direction, a rotating shell 3 that is rotatably mounted on the lower end of the lifting column 2, and a spotlight body 4 that is hinged to the lower end of the rotating shell 3. A lifting mechanism is also provided on the lifting column 2, which can drive the lifting column 2 to move up and down along the axial direction of the sleeve housing 1. A power mechanism, a clutch switching mechanism, a rotary transmission mechanism, and a swing transmission mechanism are also provided on the rotating shell 3. The rotary transmission mechanism is used to drive the rotating shell 3 to rotate relative to the lifting column 2, and the swing transmission mechanism is used to drive the spotlight body 4 to swing relative to the rotating shell 3. The power mechanism drives the rotary transmission mechanism or the swing transmission mechanism to work through the clutch switching mechanism.

[0034] Working principle of height telescopic adjustment: The lifting mechanism is mounted on the lifting column 2, and its power output end forms a transmission connection with the sleeve housing 1 or the lifting column 2. When it is necessary to adjust the lighting height of the spotlight, the lifting mechanism is activated, and the lifting mechanism outputs driving force to drive the lifting column 2 to make linear reciprocating motion along the axial direction of the sleeve housing 1. When the lifting column 2 extends upward along the inside of the sleeve housing 1, the overall lighting height of the spotlight increases; when the lifting column 2 retracts downward along the inside of the sleeve housing 1, the overall lighting height of the spotlight decreases until the target height is reached, at which point the lifting mechanism stops working, achieving height positioning.

[0035] Horizontal rotation adjustment working principle: The rotating shell 3 is rotatably installed at the lower end of the lifting column 2. The rotation transmission mechanism forms a transmission connection with the rotating shell 3 to transmit rotational driving force. When horizontal rotation adjustment is required, the power mechanism starts and switches to the transmission path with the rotation transmission mechanism through the clutch switching mechanism (at this time, the transmission path with the swing transmission mechanism is disconnected). The rotational power output by the power mechanism is transmitted to the rotation transmission mechanism through the clutch switching mechanism. The rotation transmission mechanism converts the power into a torque that drives the rotating shell 3 to rotate relative to the lifting column 2, causing the rotating shell 3 and the spotlight body 4 hinged below to rotate horizontally around the axis of the lifting column 2, realizing the horizontal angle adjustment of the lighting direction. After rotating to the target angle, the power mechanism stops or the clutch switching mechanism disconnects the rotation transmission path, completing the horizontal rotation positioning.

[0036] Vertical swing adjustment working principle: The spotlight body 4 is hinged to the lower end of the rotating shell 3. The swing transmission mechanism forms a transmission connection with the spotlight body 4 to transmit the swing driving force. When vertical swing adjustment is required, the power mechanism remains in the starting state and switches to the transmission path with the swing transmission mechanism through the clutch switching mechanism (at this time, the transmission path with the rotation transmission mechanism is disconnected). The power output by the power mechanism is transmitted to the swing transmission mechanism through the clutch switching mechanism. The swing transmission mechanism converts the rotational power into a force that drives the spotlight body 4 to swing around the hinge point, causing the spotlight body 4 to swing vertically relative to the rotating shell 3, thereby realizing the vertical angle adjustment of the lighting direction. After swinging to the target angle, the power mechanism stops or the clutch switching mechanism disconnects the swing transmission path, completing the vertical swing positioning.

[0037] Through the coordinated action of the lifting mechanism, power mechanism, and clutch switching mechanism, this spotlight can achieve automated adjustment of height extension, horizontal rotation, and vertical swing, eliminating the need for close-range manual operation. It is particularly suitable for spotlight adjustments in high-altitude installations, narrow spaces, or hard-to-reach areas, effectively reducing operational difficulty and improving adjustment efficiency.

[0038] Furthermore, a support plate 21 is spaced at the lower end of the rotating shell 3, and a hinge seat 22 is provided at the upper end of the spotlight body 4. A hinge shaft 23 is provided on the hinge seat 22, and the hinge shaft 23 is rotatably mounted on the two support plates 21.

[0039] Thus, the two support plates 21 spaced apart at the lower end of the rotating shell 3 form a symmetrical support structure. The hinge seat 22 at the upper end of the spotlight body 4 is embedded between the two support plates 21. The two ends of the hinge shaft 23 on the hinge seat 22 are respectively rotatably mounted on the two support plates 21, forming a stable hinged fit structure. When the swing transmission mechanism is working, the hinge shaft 23 can rotate smoothly relative to the support plate 21, thereby driving the spotlight body 4 to accurately complete the vertical swing action with the hinge shaft 23 as the rotation center.

[0040] In this invention, the power mechanism includes a drive motor 31 disposed inside the rotating shell 3. The output shaft of the drive motor 31 extends vertically downward out of the rotating shell 3 and is provided with a first bevel gear 32. The first bevel gear 32 is connected to a clutch switching mechanism.

[0041] Furthermore, the clutch switching mechanism includes a transmission shaft 41 rotatably mounted on the two support plates 21 respectively. A second bevel gear 42 meshing with the first bevel gear 32 is provided at the inner end of each of the two transmission shafts 41. A rotating column 43 is provided at the outer end of each of the two transmission shafts 41. A rotating collar 44 is provided at the lower end of the rotating shell 3 and outside the two support plates 21. A rotating disk 45 is rotatably mounted in each of the two rotating collars 44. The rotating column 43 and the rotating disk 45 are elastically connected by an elastic connecting component. A guide limiting mechanism is also provided between the rotating collar 44 and the rotating disk 45. The guide limiting mechanism is used to restrict the rotating disk 45 from rotating. One of the two rotating disks 45 is connected to the rotary transmission mechanism, and the other is connected to the swing transmission mechanism.

[0042] Thus, the transmission shaft 41 of the clutch switching mechanism is rotatably mounted on the two support plates 21, and the second bevel gear 42 at its inner end meshes with the first bevel gear 32 of the power mechanism, forming a symmetrical power input structure. When the drive motor 31 starts, the first bevel gear 32 rotates and synchronously drives the two second bevel gears 42 to rotate, thereby driving the transmission shaft 41 and the rotating column 43 fixed to the second bevel gears 42 to rotate synchronously, completing the initial transmission of power from the power mechanism to the clutch switching mechanism.

[0043] The rotating column 43 and the rotating disk 45 inside the rotating collar 44 are elastically linked through an elastic connection component. The guide limiting mechanism between the rotating collar 44 and the rotating disk 45 is used to restrict the rotating disk 45 to rotate only in a single direction, thereby achieving selective switching of the power transmission path. Its core switching logic is based on the forward and reverse rotation of the first bevel gear 32: when the drive motor 31 drives the first bevel gear 32 to rotate counterclockwise, the first bevel gear 32 drives the second bevel gears 42 on both sides, as well as the transmission shaft 41 and the rotating column 43 to rotate synchronously. At this time, the rotating disk 45 on the side corresponding to the rotation transmission mechanism rotates in the same direction as the direction allowed by the guide limiting mechanism, and can rotate synchronously with the rotating column 43; while the rotating disk 45 on the side corresponding to the swing transmission mechanism rotates in the opposite direction to the direction allowed by the guide limiting mechanism, and cannot rotate under the limiting action of the guide limiting mechanism. The elastic connection component on this side undergoes elastic deformation to buffer the power, and the power cannot be transmitted to the swing transmission mechanism, so the swing transmission mechanism does not work. Conversely, when the drive motor 31 drives the first bevel gear 32 to rotate clockwise, the rotation directions of the second bevel gears 42 on both sides, the transmission shaft 41, and the rotating column 43 are opposite. At this time, the rotation direction of the rotating disk 45 on the side corresponding to the rotary transmission mechanism is opposite to the direction allowed by the guide limit mechanism, and it is restricted from rotating, so power cannot be transmitted. However, the rotation direction of the rotating disk 45 on the side corresponding to the swing transmission mechanism is consistent with the direction allowed by the guide limit mechanism, and it can rotate with the rotating column 43, thereby transmitting power to the swing transmission mechanism and realizing precise switching of the power transmission path.

[0044] When horizontal rotation adjustment is required, the drive motor 31 starts and drives the first bevel gear 32 to rotate counterclockwise. Under the action of the guide limiting mechanism, the rotating disk 45 connected to the rotary transmission mechanism is released from the limit and rotates with the rotating column 43. The power is transmitted to the rotary transmission mechanism through the first bevel gear 32, the second bevel gear 42, the transmission shaft 41, the rotating column 43, the elastic connecting component, and the rotating disk 45, driving the rotating shell 3 to rotate relative to the lifting column 2. When vertical swing adjustment is required, the drive motor 31 drives the first bevel gear 32 to rotate clockwise. The guide limiting mechanism restricts the rotation of the rotating disk 45 on one side of the rotary transmission mechanism and releases the limit on the rotating disk 45 on the swing transmission mechanism. The power is transmitted to the swing transmission mechanism through the above path, driving the spotlight body 4 to swing around the hinge axis 23. Throughout the process, the power can be switched by the forward and reverse rotation of the first bevel gear 32. The guide limiting mechanism and the elastic connecting component work together to ensure smooth power switching and stable transmission without the need for additional external force triggering, realizing orderly and automatic switching between rotation and swing adjustment.

[0045] See Figure 11As shown, the elastic connection assembly includes a plurality of circular slots 51 evenly distributed around the outer end of the rotating column 43, a spring 52 and a positioning steel ball 53 are provided in the circular slots 51, and a plurality of positioning grooves 54 that cooperate with the positioning steel ball 53 are evenly distributed around the inner end of the rotating disk 45.

[0046] Multiple circular slots 51 of the elastic connecting component are evenly distributed around the outer end of the rotating column 43. A spring 52 and a positioning steel ball 53 are sequentially installed in each circular slot 51. The spring 52 is in a natural compressed state and continuously applies an outward elastic pushing force to the positioning steel ball 53, causing the positioning steel ball 53 to partially extend out of the circular slot 51. The positioning grooves 54 are evenly distributed around the inner end of the rotating disk 45. In the initial state, the positioning steel ball 53 is inserted into the corresponding positioning groove 54 under the pushing force of the spring 52, realizing the initial positioning and linkage between the rotating column 43 and the rotating disk 45.

[0047] When the rotating column 43 rotates with the transmission shaft 41 and the rotating disk 45 is not restricted by the guide limiting mechanism, the rotating column 43 directly transmits the rotational power to the rotating disk 45 through the engagement of the positioning steel ball 53 and the positioning groove 54. When the rotating column 43 rotates, the positioning steel ball 53 applies force against the groove wall in the positioning groove 54, causing the rotating disk 45 to rotate synchronously, thereby transmitting the power to the subsequent rotational transmission mechanism or swing transmission mechanism. The multiple sets of springs and steel balls evenly distributed around the circumference cooperate with the groove to ensure that the force is uniform during the power transmission process, avoid the power transmission jam caused by excessive local force, and improve the stability and reliability of the power transmission.

[0048] When the rotating disk 45 is restricted from rotating by the guide limiting mechanism, the rotational force of the rotating column 43 causes the positioning steel ball 53 to be subjected to the reverse pressure of the positioning groove 54. This pressure overcomes the elastic pushing force of the spring 52 and presses the positioning steel ball 53 back into the circular hole groove 51. The spring 52 is further compressed and stores elastic potential energy. At this time, the rotating column 43 can continue to rotate, and the positioning steel ball 53 slides along the circumferential surface of the inner end of the rotating disk 45, no longer transmitting power to the rotating disk 45, thus achieving separation of power transmission. The elastic deformation of the spring 52 can effectively buffer the impact force between the rotating column 43 and the rotating disk 45, avoid component wear caused by rigid collision, and reserve elastic reset space for subsequent power switching.

[0049] See Figure 7 , Figure 10 , Figure 11 The guide limiting mechanism shown includes a ratchet 61 located at the outer end of the rotating disk 45, and an elastic pawl 62 that cooperates with the ratchet 61 is also provided on the outer side of the rotating collar 44. An eccentric column 63 connected to the rotating transmission mechanism or the swing transmission mechanism is also provided at the outer end of the ratchet 61.

[0050] The ratchet 61 of the guide limiting mechanism is fixed to the outer end of the rotating disk 45 and rotates synchronously with the rotating disk 45; the elastic pawl 62 is installed on the outside of the rotating collar 44, and one end of it is connected to the rotating collar 44. In its natural state, the elastic pawl 62 engages with the tooth groove of the ratchet 61 under the action of elastic force; the ratchet 61 adopts a one-way tooth structure, which only allows the rotating disk 45 to rotate in one direction. When the rotating disk 45 attempts to rotate in the opposite direction, the tooth surface of the ratchet 61 abuts against the elastic pawl 62, and the elastic pawl 62 cannot deform and retract, thereby restricting the rotation of the rotating disk 45 and realizing the one-way guide limiting function.

[0051] The eccentric post 63 at the outer end of the ratchet 61 serves as a power output connector, connecting to the rotary transmission mechanism or the oscillating transmission mechanism.

[0052] See Figure 7 , Figure 8 As shown, a cavity 71 is provided at the lower end of the lifting column 2. The rotary transmission mechanism includes an annular bevel gear 72 disposed on the inner wall of the cavity 71. A boss 73 is provided at the upper end of the rotary shell 3. A third bevel gear 74 and a first gear 75 are rotatably mounted on one side of the boss 73. The third bevel gear 74 meshes with the annular bevel gear 72. A movable rod 76 moves up and down inside the rotary shell 3. A first rack 77 that meshes with the first gear 75 is provided at the upper end of the movable rod 76. A transverse slide groove 78 is provided at the lower end of the movable rod 76. An eccentric column 63 is disposed in the transverse slide groove 78.

[0053] The cavity 71 at the lower end of the lifting column 2 provides installation space for the rotary transmission mechanism, and the annular bevel gear 72 on the inner wall of the cavity is fixed. The boss 73 at the upper end of the rotating shell 3 extends into the cavity 71. The third bevel gear 74, which is rotatably mounted on the boss 73, is meshed with the annular bevel gear 72. The third bevel gear 74 is coaxially fixed with the first gear 75 to achieve synchronous rotation. The movable rod 76 is movably assembled in the rotating shell 3. The first rack 77 at its upper end meshes with the first gear 75, and the transverse slide groove 78 at its lower end slides with the eccentric column 63 of the corresponding rotary transmission mechanism. The eccentric column 63 can slide left and right along the transverse slide groove 78 to form a flexible connection for power transmission.

[0054] When horizontal rotation adjustment is required, the drive motor 31 drives the first bevel gear 32 to rotate counterclockwise. Through the clutch switching mechanism and the guide limit mechanism, the rotating disk 45 of the corresponding rotation transmission mechanism drives the ratchet 61 and the eccentric column 63 to rotate synchronously. When the eccentric column 63 rotates, it slides in the transverse groove 78 of the movable rod 76, and at the same time applies a transverse thrust to the side wall of the groove, pushing the movable rod 76 to make up-and-down reciprocating linear motion along the rotating shell 3. When the movable rod 76 moves up and down, the first rack 77 at the upper end moves synchronously, and through the meshing transmission with the first gear 75, it drives the first gear 75 and the coaxial third bevel gear 74 to rotate.

[0055] Since the annular bevel gear 72 is fixed to the inner wall of the cavity 71 of the lifting column 2, when the third bevel gear 74 meshes with the annular bevel gear 72 and rotates, it generates a driving torque along the circumference of the annular bevel gear 72. This torque drives the boss 73 and the entire rotating shell 3 to rotate around the axis of the lifting column 2, thereby driving the spotlight body 4 at the lower end of the rotating shell 3 to rotate horizontally in sync, realizing the horizontal angle adjustment of the lighting direction; the annular structure design of the annular bevel gear 72 can ensure that the third bevel gear 74 continuously meshes and transmits along its circumference, realizing horizontal rotation.

[0056] See Figure 9 , Figure 10 As shown, the swing transmission mechanism includes a vertical plate 81 located at the upper end of the spotlight body 4, a vertical groove 82 provided on the vertical plate 81, and another eccentric column 63 located in the vertical groove 82.

[0057] The vertical plate 81 of the swing transmission mechanism is fixed to the upper end of the spotlight body 4, and the vertical groove 82 opened on the vertical plate 81 extends in the vertical direction; the eccentric column 63 corresponding to the swing transmission mechanism is fixed to the outer end of the ratchet 61 and embedded in the vertical groove 82. The eccentric column 63 can slide up and down along the vertical groove 82 and can rotate relative to the vertical groove 82 to form a sliding connection for power transmission; the spotlight body 4 is hinged to the support plate 21 of the rotating shell 3 through the hinge shaft 23, providing a rotation fulcrum for the swing action.

[0058] When vertical swing adjustment is required, the drive motor 31 drives the first bevel gear 32 to rotate clockwise. Through the clutch switching mechanism and the guide limit mechanism, the rotating disk 45 of the corresponding swing transmission mechanism drives the ratchet 61 and the eccentric column 63 to rotate synchronously. The eccentric column 63 moves in a circular motion around the rotation center of the ratchet 61. During the rotation, it slides up and down along the vertical groove 82 of the vertical plate 81, and at the same time applies a periodic alternating up and down thrust to the side wall of the vertical groove 82.

[0059] Since the spotlight body 4 uses the hinge shaft 23 as its rotation fulcrum, when the eccentric column 63 applies an upward thrust to the vertical slide 82, it pushes the vertical plate 81 and the spotlight body 4 to swing upward around the hinge shaft 23; when the eccentric column 63 rotates to the other side and applies a downward thrust to the vertical slide 82, it pulls the vertical plate 81 and the spotlight body 4 to swing downward around the hinge shaft 23. The continuous rotation of the eccentric column 63 drives the spotlight body 4 to reciprocate vertically around the hinge shaft 23, thus achieving vertical angle adjustment of the lighting direction. The rotation angle of the eccentric column 63 determines the swing angle of the spotlight body 4. By controlling the rotation angle of the drive motor 31, the vertical lighting angle of the spotlight body 4 can be precisely adjusted.

[0060] See Figure 2 , Figure 6 As shown, a vertical slide rail is provided on the inner wall of the sleeve housing 1, and a slider 92 that cooperates with the vertical slide rail is provided on the outer wall of the lifting column 2. The lifting mechanism includes a second rack 93 provided on the inner wall of the sleeve housing 1, and a reduction motor 94 is provided on the lifting column 2. A second gear 95 that meshes with the second rack 93 is provided on the output shaft of the reduction motor 94.

[0061] A vertical slide rail is provided on the inner wall of the sleeve housing 1, and a slider 92 fixed at a corresponding position on the outer wall of the lifting column 2 is embedded in the vertical slide rail to form a sliding fit structure. The vertical slide rail extends along the axial direction of the sleeve housing 1, providing a precise sliding guide trajectory for the slider 92, thereby restricting the lifting column 2 to only make linear reciprocating movements along the axial direction of the sleeve housing 1, and avoiding twisting, offset or jamming during the extension and retraction of the lifting column 2.

[0062] When the spotlight illumination height needs to be increased, the geared motor 94 is started and controlled to rotate in the reverse direction. The output shaft of the geared motor 94 drives the second gear 95 to rotate synchronously in the reverse direction. Since the second rack 93 is fixed, the second gear 95 rolls upward along the second rack 93 under the meshing force, thereby driving the lifting column 2 fixed to it to move upward. The slider 92 on the outer wall of the lifting column 2 slides upward synchronously along the vertical slide rail of the sleeve shell 1, and the lifting column 2 retracts into the sleeve shell 1. When the illumination height needs to be decreased, the geared motor 94 is controlled to rotate in the forward direction, and the second gear 95 rolls downward along the second rack 93, driving the lifting column 2 and the slider 92 to slide downward synchronously, realizing the extension action of the lifting column 2.

[0063] In this invention, a lamp holder 100 is also provided at the lower end of the sleeve housing 1, and spring clips 101 are symmetrically arranged on the outer wall of the lamp holder 100.

[0064] Thus, the lamp holder 100 fixed at the lower end of the sleeve shell 1 serves as the mounting base for the spotlight. Its structure is suitable for conventional installation scenarios (such as pre-drilled holes in the ceiling), providing a stable mounting support point for the entire spotlight. Meanwhile, the spring clips 101 symmetrically arranged on the outer wall of the lamp holder 100 are made of elastic metal material and are used to install the lamp holder 100 into the pre-drilled holes in the ceiling.
