[0002] During film and television shooting, film and television light stands are indispensable equipment. Their main function is to support and fix film and television lights to meet the requirements of different shooting scenes for lighting angle, height and position. However, existing film and television light stands have many shortcomings. For example, the angle adjustment method of most light stands is relatively simple, and usually only simple pitch or rotation adjustment can be performed in a limited number of directions, making it difficult to achieve complex multi-angle combination adjustment and unable to meet diverse shooting needs; some light stands are cumbersome to operate when adjusting the angle, which requires a lot of time and effort, reducing shooting efficiency.

[0003] In the prior art, such as Chinese patent publication number: CN114217494A, a multifunctional film and television lamp is disclosed, including an adjustment bracket; a side support member, which is circumferentially symmetrically arranged at the lower end of the adjustment bracket, and one end of the side support member is hinged to the adjustment bracket; a telescopic guide rod, which is coaxially fixed below the adjustment bracket, and a plurality of support rods corresponding to the side support members are rotatably connected to the telescopic guide rod, and one end of the support rod is hinged to the side support member; an insect-proof lighting assembly, which is arranged above the adjustment bracket and is used for film and television lighting; and a positioning and deflection adjustment assembly, which is installed below the insect-proof lighting assembly, and the positioning and deflection adjustment assembly can adjust the illumination angle of the insect-proof lighting assembly.

[0004] The existing light stands have relatively simple functions and lack functions such as quick installation and disassembly, adaptive height adjustment, and convenient connection with other equipment. They are difficult to adapt to the complex and changeable working environment of film and television shooting sites. When in use, they lack an effective folding and storage structure, which is not conducive to use in multi-scene transfer conditions. Therefore, there is an urgent need to design a multi-functional angle-adjustable film and television light stand to solve the above problems.

The side panel bracket is arranged perpendicular to the connecting component, and there are two side panel brackets in total. The two side panel brackets are fixedly connected in a linear array at the left and right sides of the top end surface of the connecting component.

[0013] Preferably, a rotating shaft is installed on the inner side of the two side plate brackets, and a driven bevel gear is fixedly connected to the side of the rotating shaft facing the extension shaft. The driven bevel gear is engaged with the driving bevel gear arranged at the top end of the extension shaft for transmission, and a supporting guide mechanism is fixedly connected to the outer side of the rotating shaft.

[0014] Preferably, a slot is provided inside the support guide mechanism, a longitudinal slot is provided on the right side of the slot, and a support plate assembly is fixedly connected to the right side of the support guide mechanism. There are two support plate assemblies in total, and the two support plate assemblies are fixedly connected in a linear array at the front and rear positions of the right end face of the support guide mechanism, and a servo motor A is installed at the front end of the support plate assembly on the front side.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is in use, a composite mechanical structure of "push rod drive-support arm linkage-guide constraint" is formed by unfolding the push rod and the vertical fixed connection between the bracket mechanism, and the support arm mechanism is slidably matched with the guide groove through the rotating shaft assembly and the rotational connection with the connecting assembly. When the push rod is unfolded and extended, the two bracket mechanisms are pushed to move to both sides, and the support arm mechanisms synchronously rotate around the connecting assembly and slide along the guide groove, thereby realizing rapid switching from a compact folded state to a stable unfolded state; the meshing transmission of the driving gear and the driven gear transmits power to the extension shaft through the friction transmission chain of the connecting shaft, the pulley assembly and the belt assembly, thereby forming a mechanical transmission path for horizontal angle adjustment; this structure ensures that there is no empty stroke and no slipping during the horizontal adjustment process through the rigid transmission of the gear rack and the limiting effect of the guide groove, and the support arm mechanism is completely stored inside the bracket mechanism in the folded state, reducing space occupancy and solving the problems of inconvenient storage and adjustment jamming of the existing lamp stand.

[0018] 2. When the present invention is used, the driving bevel gear at the top of the extension shaft is meshed with the driven bevel gear of the rotating shaft to convert the horizontal rotational motion into vertical rotational motion, driving the support guide mechanism to rotate around the rotating shaft, thereby realizing the pitch adjustment of the lamp installation part in the vertical plane; the driven rack inside the support guide mechanism is meshed with the stepping gear driven by the servo motor A to form a gear rack transmission pair, driving the extension bracket to rise and fall along the longitudinal groove to realize adaptive adjustment of the height; the turntable assembly is driven to rotate by the servo motor B, and cooperates with the mechanical locking structure in which the positioning pin rod is inserted into the positioning pin hole to realize precise positioning of the horizontal plane angle. The mechanical system breaks through the limitation of the single-direction adjustment of the traditional lamp stand through the orthogonal transmission of the bevel gear, the linear transmission of the gear rack and the rigid locking of the positioning pin, forming a "horizontal-vertical-height" three-dimensional linkage adjustment system, and there is no flexible deformation during the adjustment process. The angle is maintained by mechanical locking rather than friction, which solves the problems of narrow adjustment range and unreliable locking of the existing lamp stand.

[0019] 3. When the present invention is in use, the threaded structure of the lamp connector cooperates with the positioning pin hole-positioning pin rod locking structure of the sleeve assembly and the connector to form a dual fixing mechanism of "thread pre-tightening-pin hole positioning", ensuring the coaxiality and torsional rigidity of the lamp after installation; the rotational connection design of the support arm mechanism and the connecting assembly, combined with the standardized external mounting interface (such as threaded holes and cold shoes), allows auxiliary equipment to rotate and adjust synchronously with the support arm mechanism, realizing coordinated angle adjustment of the light and reflectors, softboxes, etc.; the movable wheels (with self-locking universal wheels) at the bottom of the bracket mechanism cooperate with the deployment push rod, and through the mechanical operation process of "wheel unlocking and moving-push rod adjusting spacing-wheel locking and supporting", the lamp stand can quickly switch between mobile flexibility and positioning stability; the fixed connection between the partition assembly and the connecting assembly provides a mounting carrier for accessories such as power supplies and control switches, and reduces external cable connections through mechanical integration. Through the mechanical design of threaded connection, pin hole positioning, rotating pair linkage and movable support, this structure solves the problems of cumbersome connection of existing lamp stand equipment, difficult coordination of multiple devices, and poor adaptability to complex environments.

[0020] 4. When the present invention is in use, a rigid frame is formed by the U-shaped structure of the bracket mechanism and the unfolding push rod and the partition assembly. The arm mechanism is rotatably connected to the guide groove and the connecting assembly of the bracket mechanism through two rotating shaft assemblies to form a triangular stable support structure. After the unfolding push rod locks the spacing of the bracket mechanism, the sliding constraint of the rotating shaft assembly of the arm mechanism in the guide groove and the bearing support of the connecting assembly can evenly distribute the weight of the lamp to the bracket mechanism and the base through the mechanical transmission chain, avoiding single-point stress deformation. Compared with the single-column cantilever structure of the existing lamp stand, the frame-type mechanical connection significantly improves the overall anti-overturning moment, ensuring that there is no shaking or displacement during large-angle adjustment.

[0021] 5. When the present invention is in use, the driving gear and the driven gear, the pulley assembly and the belt assembly, the driving helical gear and the driven helical gear and other transmission components are all detachably installed (such as key connection, bolt fixation), and the connecting components, side panel brackets and other supporting structures have reserved maintenance openings. When maintenance or replacement of transmission components is required, the transmission chain components can be quickly separated by mechanical operations such as removing the positioning pin rod and loosening the bearing seat bolts, without the need to disassemble the lamp stand as a whole. The modular mechanical design shortens the daily maintenance time to / of the traditional integrated structure, and the transmission ratio can be flexibly adjusted to meet different adjustment speed requirements by replacing gears, belts and other components with different numbers of teeth.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. Example

[0024] See also Figures 1-8 As shown, the present invention provides a technical solution: a multifunctional angle-adjustable film and television light stand, comprising a bracket mechanism 1, the main body of the bracket mechanism 1 being a U-shaped structure with an opening facing inward, and the bracket mechanism 1 being provided at two locations, the inner sides of the two bracket mechanisms 1 being fixedly connected with an expansion push rod 2013, the expansion push rod 2013 being arranged perpendicular to the bracket mechanism 1; The inner sides of the two unfolding push rods 2013 are fixedly connected with the partition assembly 2012, and the outer sides of the partition assembly 2012 are fixedly connected with the connecting assembly 2011. There are two connecting assemblies 2011 in total, and the two connecting assemblies 2011 are fixedly connected to the upper and lower side positions of the partition assembly 2012 in opposite directions, and the inner sides of the two connecting assemblies 2011 are rotatably connected to the support arm mechanism 2, and the interior of the support arm mechanism 2 is installed with a rotating shaft assembly 201. The interior of each support arm mechanism 2 is fixedly connected with two rotating shaft assemblies 201 in a linear array, and guide grooves 1011 are provided on the upper and lower sides of the interior of the bracket mechanism 1. The guide grooves 1011 are arranged horizontally, and the side of the support arm mechanism 2 away from the connecting assembly 2011 is slidably connected in the guide groove 1011 through the rotating shaft assembly 201. The unfolding push rod 2013 is used to adjust the distance between the two bracket mechanisms 1. , and a moving wheel 101 is installed on the bottom end surface of the bracket mechanism 1. There are four moving wheels 101 in total, wherein every two laterally adjacent moving wheels 101 form a group, and the two groups of moving wheels 101 are respectively fixedly connected to the left and right sides of the bottom end surface of the two bracket mechanisms 1, and the moving wheels 101 are a universal wheel structure with a self-locking structure, and the bottom end of the rotating shaft assembly 201 located at the left front end is coaxially mounted with a driving gear 3, and the bottom center position of the connecting assembly 2011 located on the lower side is mounted with a connecting shaft 301 through a bearing seat, and the bottom end of the connecting shaft 301 is coaxially mounted with a driven gear 3011, which is meshed with the driving gear 3 for transmission, and the bottom end of the connecting assembly 2011 is also mounted with a driven shaft 3014, and the top end of the driven shaft 3014 is fixedly connected with an extension shaft 4, and the extension shaft 4 passes through the connecting assembly 2011 located on the upper side toward the upper side.

[0025] In this embodiment, when in use, in the initial state, the two bracket mechanisms 1 are close to each other, the deployment push rod 2013 is in the retracted state, and the arm mechanism 2 slides along the guide groove 1011 to the inner side of the bracket mechanism 1 through the rotating shaft assembly 201. The overall structure is compact and easy to transport and store; Deployment adjustment process: When the light stand needs to be used, the deployment push rod 2013 (such as an electric push rod) is activated. It extends outward and pushes the two bracket mechanisms 1 to move to the sides, increasing the distance between them. At this time, due to the rotation connection characteristics of the connecting component 2011, the arm mechanism 2 rotates synchronously around the connecting component 2011 as the bracket mechanism 1 moves. At the same time, the inner shaft component 201 slides laterally along the guide groove 1011 (the guide groove 1011 limits the movement direction of the shaft component 201, ensuring that the arm mechanism 2 is smoothly deployed); When the bracket mechanism 1 is unfolded to the required width, the driving gear 3 at the bottom end of the rotating shaft assembly 201 located at the left front end can be rotated by external power (such as manual or motor drive), and the driving gear 3 is engaged with the driven gear 3011 at the bottom end of the connecting shaft 301 to drive the connecting shaft 301 to rotate. The connecting shaft 301 is synchronously driven by the friction transmission of the pulley assembly 3012 and the belt assembly 3013 to rotate, thereby rotating the extension shaft 4 and the driving bevel gear 401 at the top to achieve horizontal angle transmission. By unfolding the push rod 2013 and the linkage design of the support arm mechanism 2, the light stand can be quickly unfolded and folded, solving the problem of inconvenient storage of the existing light stand; the meshing transmission structure of the driving gear 3 and the driven gear 3011 provides a basic power transmission path for horizontal angle adjustment, which significantly improves the adjustment efficiency compared to the traditional manual step-by-step adjustment method, and the structure is stable and reliable, which can meet the needs of rapid deployment on film and television shooting sites. Example

[0026] like Figures 1-6 As shown, the bottom ends of the connecting shaft 301 and the driven shaft 3014 are coaxially mounted with pulley assemblies 3012, wherein one pulley assembly 3012 is coaxially arranged with the driven gear 3011, and a belt assembly 3013 is also mounted on the outside of the two pulley assemblies 3012, and the belt assembly 3013 and the pulley assembly 3012 together constitute a friction transmission structure, the top end of the extension shaft 4 is coaxially mounted with a driving bevel gear 401, and the top surface of the connecting assembly 2011 on the upper side is fixedly connected to a side plate bracket 4011, and the side plate bracket 4011 is fixedly connected to the side plate bracket 4011. The connecting components 2011 are arranged vertically, and there are two side panel brackets 4011. The two side panel brackets 4011 are fixedly connected in a linear array at the left and right sides of the top surface of the connecting component 2011. The inner side of the two side panel brackets 4011 is installed with a rotating shaft 4012. The side of the rotating shaft 4012 facing the extension shaft 4 is fixedly connected with a driven bevel gear 4013. The driven bevel gear 4013 is engaged with the driving bevel gear 401 arranged at the top of the extension shaft 4 for transmission, and the outer side of the rotating shaft 4012 is fixedly connected with a support guide mechanism 5.

[0027] In this embodiment, when in use, the driving bevel gear 401 at the top of the extension shaft 4 rotates along with the driven shaft 3014 and meshes with the driven bevel gear 4013 at one end of the rotating shaft 4012, converting the horizontal rotational motion into the vertical rotational motion of the rotating shaft 4012. The supporting guide mechanism 5 fixed to the outside of the rotating shaft 4012 rotates synchronously therewith, thereby achieving angular adjustment of the light installation position within the vertical plane (e.g., pitch angle change). The slot provided inside the support guide mechanism 5 can be inserted into the extension bracket 5013. When the servo motor A5011 is started, its output shaft drives the stepping gear 5012 to rotate. The stepping gear 5012 engages with the driven rack 5014 at the bottom end of the extension bracket 5013, driving the extension bracket 5013 to move up and down along the longitudinal slot of the support guide mechanism 5, thereby realizing adaptive adjustment of the height of the lamp stand. The support plate mechanism 6 at the top end of the extension bracket 5013 drives the turntable assembly 6011 to rotate via the servo motor B601, thereby further adjusting the horizontal rotation angle of the lamp. After the adjustment is completed, the positioning pin rod 6015 is inserted into the positioning pin hole 6013 of the sleeve assembly 6014 and the connector 6012 to lock the position of the turntable assembly 6011, thereby ensuring stability after the angle adjustment. The helical gear transmission structure converts horizontal movement into vertical movement, breaking through the limitation of single-direction adjustment of traditional light stands and enabling multi-angle combination adjustment of the light in the horizontal and vertical planes; the rack-and-pinion transmission structure supporting the guide mechanism 5 and the extension bracket 5013 realizes precise electric adjustment of the light stand height without the need for manual raising and lowering, significantly improving the convenience of operation; the cooperation between the positioning pin rod 6015 and the positioning pin hole 6013 provides a reliable locking mechanism for angle adjustment, avoiding angle deviation caused by factors such as vibration during shooting, and solving the problem of insufficient stability of existing light stands after adjustment. Example

[0028] like Figure 2-Figure 8As shown, a slot is provided inside the support guide mechanism 5, a longitudinal slot is provided on the right side of the slot, and a support plate assembly 501 is fixedly connected to the right side of the support guide mechanism 5, and there are two support plate assemblies 501. The two support plate assemblies 501 are fixedly connected to the front and rear positions of the right end face of the support guide mechanism 5 in a linear array, and a servo motor A5011 is installed at the front end of the support plate assembly 501 on the front side, and a stepping gear 5012 is installed on the rear output shaft of the servo motor A5011. The servo motor A5011 and the stepping gear 5012 together constitute a power output structure, and an extension bracket 5013 is inserted into the interior of the support guide mechanism 5, and the extension bracket 5013 and the support guide mechanism 5 together constitute an extension structure. One end of the slotted support guide mechanism 5 is fixedly connected to a driven rack 5014, which is engaged with the stepping gear 5012 for transmission, and the top of the extension bracket 5013 is fixedly connected to the support plate mechanism 6, and the bottom end of the support plate mechanism 6 is installed with a servo motor B601, and a turntable assembly 6011 is installed on the top output shaft of the servo motor B601. The top center position of the turntable assembly 6011 is fixedly connected to a connector 6012, and a sleeve assembly 6014 is sleeved on the outer side of the connector 6012. A positioning pin hole 6013 is provided inside the sleeve assembly 6014 and the connector 6012, and a positioning pin rod 6015 is inserted into the interior of the positioning pin hole 6013. A lamp connector 6016 with a threaded structure is fixedly connected to the top surface of the sleeve assembly 6014.

[0029] In this embodiment, when in use, the lamp connector 6016 at the top of the sleeve assembly 6014 adopts a threaded structure and can be directly screwed onto the mounting base of a standard film and television lamp to achieve rapid fixing of the lamp. At the same time, after the connector 6012 and the sleeve assembly 6014 are locked by the positioning pin rod 6015, the coaxiality of the lamp after installation is ensured, avoiding angular deviation caused by loose threaded connection. The rotating connection design between the arm mechanism 2 and the connecting assembly 2011 allows auxiliary equipment such as reflectors and softboxes to be installed on the outside of the arm mechanism 2 (for example, fixed by clips or bolts). When the arm mechanism 2 is unfolded or the angle is adjusted along with the bracket mechanism 1, the auxiliary equipment moves synchronously, achieving coordinated angle adjustment of the light and the auxiliary equipment. The moving wheel 101 at the bottom of the bracket mechanism 1 adopts a universal wheel with a self-locking structure. When moving, the self-locking structure is released, and the position of the light stand can be flexibly adjusted; when positioning, the universal wheel is locked, and the spacing of the bracket mechanism 1 is adjusted in conjunction with the unfolded push rod 2013 to keep the light stand stable on uneven ground. In addition, the partition assembly 2012 can be used to install power sockets, control switches and other accessories to improve the functional integration of the light stand. The threaded structure of the lamp connector 6016 and the positioning pin locking mechanism realize the rapid installation and precise positioning of the lamp, which is more stable and reliable than the traditional snap-on installation; the extended installation function of the arm mechanism 2 enables the light stand to carry a variety of auxiliary equipment simultaneously without the need for additional brackets, simplifying the equipment deployment process on the shooting site; the cooperation of the moving wheel 101 and the horizontal adjustment mechanism enables the light stand to be quickly moved and stably positioned in a variety of terrains, solving the problem of insufficient adaptability of existing light stands in complex environments, and significantly improving the work efficiency and scene compatibility of film and television shooting.
