Description

Technical Field

[0001] The present invention relates to the technical field of cameras, and in particular to a backpack device for assisting shooting. Background Art

[0002] Currently, in the field of photography, photographers often need to hold over 10kg of photographic equipment for extended periods of time while maintaining precise control. Therefore, there is an urgent need for a photography-assisted carrying device to reduce the photographer's workload and enhance control over the camera and equipment, thereby improving both quality and efficiency.

[0003] The existing technical solutions of the backpack device for auxiliary photography have the following problems: (1) The structure is unreasonable, and the user cannot properly distribute the weight distribution of the photographic equipment when using the device; (2) When used as a single backpack device, it only transfers the weight of the photographic equipment to the back or waist, and its function is relatively simple; (3) There is a lack of control scheme, which sacrifices some of the control functions of the photographic equipment, making it difficult for the user to make subtle adjustments and work on the photographic equipment, and sacrificing some of the control functions, further limiting the user's efficiency. Summary of the Invention

[0004] In order to solve the above problems, the primary purpose of the present invention is to provide a carrying device for auxiliary shooting, which has a reasonable structure so that the user can reasonably distribute the weight distribution of the photographic equipment when using the device, thereby achieving the benefit of increasing working time.

[0005] Another object of the present invention is to provide a backpack device for assisting shooting, which can improve the user's control over the photographic equipment and provide multiple power supply and control methods.

[0006] In order to achieve the above objectives, the technical solutions of the present invention are as follows.

[0007] A backpack device for assisting photography, characterized in that the device includes a backpack mechanism for being carried on the user's back, an extension arm that can be rotated on the backpack mechanism to adjust its tilt angle, and a balancing mechanism for mounting a three-axis stabilizer; the backpack mechanism is movably connected to one end of the extension arm, and the balancing mechanism is disposed at the other end of the extension arm. In the present invention, the user carries the backpack mechanism on their back, preferably at the waist, with the three-axis stabilizer supported by the extension arm and the balancing mechanism. This eliminates the need for hand-held use, freeing the user's hands and improving control over the photographic equipment. The rotation of the extension arm on the backpack mechanism to adjust its tilt angle allows the device to distribute the weight of the photographic equipment appropriately, allowing the user to more effectively bear the weight of the device and other photographic equipment when carrying the device, thereby increasing working time. The adjustable position of the extension arm facilitates adjustment of the spatial position of the three-axis stabilizer relative to the user, allowing the user to use the three-axis stabilizer installed on the device in a variety of environments.

[0008] Furthermore, the balancing mechanism includes a balance bar for mounting a three-axis stabilizer and a counterweight module for increasing the stability of the balance bar. The counterweight module is detachably mounted on the balance bar, and the balance bar is movably connected to an extension arm. The configuration module is used to increase the stability of the balance bar, making the balance bar equipped with the three-axis stabilizer more stable. The movable connection between the balance bar and the extension arm facilitates adjustment of the center of gravity of the device equipped with the three-axis stabilizer, as well as adjusting the spatial position of the three-axis stabilizer.

[0009] Furthermore, the counterweight module can be a weight counterweight assembly, a V-mount power supply box counterweight assembly, an Anton power supply box counterweight assembly, or a three-axis stabilizer handle counterweight assembly. The configuration of the above-mentioned multiple counterweight modules can provide multiple power sources and increase the stability of the balance bar.

[0010] Furthermore, the stabilizer bar is a retractable structure; a control module for controlling the three-axis stabilizer and the follow-focus motor is also connected to the stabilizer bar. The retractable stabilizer bar facilitates height adjustment of the three-axis stabilizer, and the control module further facilitates operational adjustments of the three-axis stabilizer and the follow-focus motor, enabling a variety of control methods.

[0011] Furthermore, the balance pole includes balance pole interfaces at both ends and a telescopic pole in the middle, and a telescopic pole knob for controlling the extension and retraction of the telescopic pole is sleeved on the telescopic pole; the balance pole also includes a bent arm connector and a C-shaped swivel member, one end of the bent arm connector is rotatably connected to the C-shaped swivel member, and the other end of the bent arm connector is movably connected to the extension arm; the open end of the C-shaped swivel member is rotatably connected to the telescopic pole. The design of the open end of the C-shaped swivel member being rotatably connected to the telescopic pole can be achieved by providing a swivel bearing between the C-shaped swivel member and the telescopic pole, the open end of the C-shaped swivel member being connected to the outer ring of the swivel bearing, and the swivel bearing being sleeved on the telescopic pole. The control module is provided on the bent arm connector. The balance pole interfaces at both ends of the balance pole can be respectively installed with a three-axis stabilizer and a counterweight module, which are preferably NATO interfaces. The rotation of the C-shaped rotating member on the telescopic rod and the rotatable connection between the curved arm connector and the C-shaped rotating member make it easier to adjust the center of gravity of the entire device, making the user more comfortable when wearing the device.

[0012] Furthermore, the control module is provided with a monitor expansion slide, and the monitor expansion slide is provided with an expansion interface, which can be a threaded interface, a cold shoe interface, or other interfaces, and can be connected to a monitor of a photographic device or other equipment.

[0013] Furthermore, the extension lever comprises a lever arm, a connecting piece, and a force adjustment knob for adjusting the lever arm's load and shock absorption capacity. The connecting piece is rotatably connected to one end of the lever arm, and the force adjustment knob is movably mounted on the lever arm. There are two extension lever arms, one of which has a circular tube interface at its front end for movably connecting to the curved arm connector, and its rear end rotatably connected to the front end of the other extension lever arm via its connecting piece. The rear end of the other extension lever arm has a longitudinal center of gravity adjustment interface for connecting to a carrying mechanism.

[0014] Furthermore, the carrying mechanism includes a center of gravity adjusting member located between the carrying mechanism and the extension arm for adjusting the overall center of gravity of the device. One end of the center of gravity adjusting member is detachably arranged on the carrying mechanism, and the other end of the center of gravity adjusting member is movably connected to the extension arm.

[0015] Furthermore, the center of gravity adjustment member includes an L-shaped structural member, a transverse center of gravity adjustment interface, and a hand twist. One end of the L-shaped structural member is detachably connected to the carrying mechanism, and the transverse center of gravity adjustment interface is provided at the other end of the L-shaped structural member. The hand twist is movably provided on the transverse center of gravity adjustment interface. By rotating the hand twist, the tilt angle between the transverse center of gravity adjustment interface and the L-shaped structural member can be changed. A lever arm mounting interface for movably connecting to an extended lever arm is fixedly connected to the side of the transverse center of gravity adjustment interface. The lever arm mounting interface can be a longitudinal mounting interface or a longitudinal turbine center of gravity adjustment interface. When the lever arm mounting interface is a longitudinal turbine center of gravity adjustment interface, in addition to being an interface for movably connecting to the extended lever arm, a worm hand twist can also be movably connected to the longitudinal turbine center of gravity adjustment interface. The worm hand twist and the longitudinal turbine center of gravity adjustment interface are equipped with a worm gear transmission. Utilizing the high transmission ratio and self-locking function of the worm gear, the longitudinal center of gravity can be easily controlled by rotating the worm hand twist. The same transverse center of gravity adjustment interface can also be used in a consistent manner.

[0016] Furthermore, the carrying mechanism is provided with a back extension slide for installing photographic equipment; the carrying mechanism is provided with a safety mechanism for protecting the photographic equipment on the back extension slide, and the safety mechanism includes a safety rope and a protective frame.

[0017] The beneficial effects of the present invention are that, compared to the prior art, in the present invention, the user carries the carrying mechanism on their back, preferably at the waist, with the three-axis stabilizer supported by an extension arm and a balancing mechanism, eliminating the need for hand-held support. Furthermore, the extension arm rotates on the carrying mechanism to adjust its tilt angle, enabling the device to distribute the weight of the photographic equipment appropriately, allowing the user to more effectively bear the weight of the device and other photographic equipment while carrying the device, thereby increasing working time. Furthermore, the adjustable position of the extension arm facilitates the adjustment of the spatial position of the three-axis stabilizer relative to the user, allowing the user to use the device in a variety of different environments.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] To achieve the above objectives, the technical solutions of the present invention are as follows.

[0032] like Figure 1-12 As shown, the present invention provides a carrying device for auxiliary shooting, including a carrying mechanism (preferably a carrying belt 1), an extension arm 2, a center of gravity adjustment member 3, a balance bar 4, a counterweight module 5, a control module 6, an expansion module, and a safety mechanism.

[0033] like Figure 1-12As shown, the back of the waist belt 1 is connected to a lightweight aluminum alloy hollow tube 12; the middle extension slide seat 13 is connected to the upper and lower sections of the lightweight aluminum alloy hollow tube 12; the left arm quick-release seat 14 and the right arm quick-release seat 17 are connected to the left and right sections of the lightweight aluminum alloy hollow tube 12 respectively; the left safety frame quick-release seat 15 and the right safety frame quick-release seat 16 are connected to the lightweight aluminum alloy hollow tube 12 and are located on either side of the left arm quick-release seat 14 and the right arm quick-release seat 17 respectively; the upper rope buckle 18 is connected to the lightweight aluminum alloy hollow tube 12 via rivets. When the user wears the waist belt, the weight of the photographic equipment is transferred to the user through the waist belt.

[0034] The extended lever arm 2 includes a lever arm 21, a force adjustment knob 22, a connector 24, a circular tube interface 25, and a longitudinal center of gravity adjustment interface 26. The connector 24 and lever arm 21 alternate and are rotatably connected via a connecting shaft 23. The force adjustment knob 22 is mounted on the upper end of the lever arm 21, and the load and shock absorption capacity of the lever arm can be adjusted by rotating the force adjustment knob 22. This adjustment method is conventional. A spring is provided within the lever arm 21. The spring within the lever arm 21 is fixed at one end and connected to a threaded transmission structure at the other end. The force adjustment knob 22 can be used to control the threaded transmission structure to raise or lower the spring within the lever arm, changing the angle between the spring and the lever arm and the length of the opening, thereby adjusting the load and shock absorption capacity of the lever arm. One end of the lever arm 21 is connected to the circular tube interface 25, and the other end is connected to the longitudinal center of gravity adjustment interface 26. The circular tube interface 25 connects to the curved arm connector 45 of the balance bar 4, and the longitudinal center of gravity adjustment interface 26 connects to the longitudinal mounting interface 34 of the center of gravity adjustment member 3. Rotating the longitudinal center of gravity adjustment interface 26 controls the tilt angle of the extension arm 2, thereby adjusting the overall center of gravity of the device carried by the user to the center of the user's longitudinal axis. This reduces the user's burden. By transferring the weight of the entire extension arm, the camera equipment can be adjusted and relocated to meet the user's space requirements, increase their working time, and improve the user experience.

[0035] The center of gravity adjustment member 3 includes an L-shaped structural member 31, a transverse center of gravity adjustment interface 32, and a hand knob 33. One end of the L-shaped structural member 31 is a dovetail slide that can be connected to the left arm body quick-release seat 14 or the right arm body quick-release seat 17 in the carrying belt 1; the other end is a transverse mounting interface 311 that can be connected to the transverse center of gravity adjustment interface 32; the transverse center of gravity adjustment interface 32 is connected to the transverse mounting interface 311, and a rotating hand knob 33 is movably set on the transverse center of gravity adjustment interface 32. By rotating the hand knob 33, the inclination angle between the transverse center of gravity adjustment interface 32 and the L-shaped structural member 31 can be changed, thereby adjusting the overall center of gravity of the device carried by the user to the center of the user's transverse axis, further reducing the user's usage burden; the other side of the transverse center of gravity adjustment interface 32 is a longitudinal mounting interface 34 that can be connected to the longitudinal center of gravity adjustment interface 26 of the extension arm 2. The above-mentioned transverse center of gravity adjustment interface 32 is implemented by setting its inclination angle according to the existing technology, such as through the engagement of two toothed discs. The inclination angle can be adjusted by rotating the meshing position of the two toothed discs.

[0036] Another implementation of the center of gravity adjustment member 3 includes an L-shaped structural member 31, a transverse center of gravity adjustment interface 32, a manual knob 33, a worm manual knob 35, and a longitudinal turbine center of gravity adjustment interface 36. The worm manual knob 35 and the longitudinal turbine center of gravity adjustment interface 36 incorporate a built-in worm gear transmission. Leveraging the high transmission ratio and self-locking function of the worm gear, the longitudinal center of gravity can be easily controlled by rotating the worm manual knob 35. A similar design can also be used for the transverse center of gravity adjustment interface.

[0037] The balance pole 4 comprises NATO ports 41 and electronic ports 42 at each end, a central telescopic rod 43, a telescopic rod knob 44, a curved arm connector 45, a C-shaped swivel member 46, and a swivel bearing 47. The central telescopic rod 43 is constructed from several carbon fiber tubes, and its length can be adjusted by rotating the rod knob 44. The NATO ports 41 and electronic ports 42 are connected to each end of the central telescopic rod 43. The electronic ports 42 at both ends are connected internally within the central telescopic rod 43, forming an electronic circuit. One end of the curved arm connector 45 is connected to the C-shaped swivel member 46, and the two can rotate relative to each other via a screw shaft. The other end can be directly sleeved on the circular tube interface 25 in the extension arm 2 along the axial direction of the circular tube. The open end of the C-shaped swivel member 46 is connected to the outer ring of the swivel bearing 47, and the C-shaped swivel member 46 can rotate relative to the swivel bearing 47. The inner ring of the swivel bearing 47 is connected and fixed to the middle telescopic rod 43, so the middle telescopic rod 43 can rotate relative to the swivel bearing 47, allowing the user to adjust the operating angle of the photographic equipment at will. The length of the circular tube can be adjusted by rotating the knob, allowing the photographic equipment to be positioned according to the rotation radius with the user as the center. The length of the circular tube can also be adjusted to balance the center of gravity of the photographic equipment at one end and the counterweight module at the other end, reducing the load on the user.

[0038] The counterweight module 5 includes a weight counterweight assembly 54 or a V-port power supply box counterweight assembly 55 or an Anton power supply box counterweight assembly 53 or a three-axis stabilizer handle counterweight assembly 52; and the weight counterweight assembly also includes a NATO slider 51. The weight counterweight assembly includes a weight 543, an intermediate frame 544, a bottom pendulum counterweight structure 541, and a locking pin 542. The weight 543 is provided with internal and external threads at both ends, and the weights 543 can be connected to each other through corresponding internal and external threads. Threaded holes are provided around the intermediate frame 544. The upper end of the intermediate frame 544 is connected to the NATO slider 51, and the NATO slider 51 can be connected to the NATO interface 41 at one end of the balance bar 4. The bottom is the installation position of the pendulum counterweight structure 541. The locking pin 542 is set at the bottom of the middle frame 544, and the pendulum counterweight structure 541 is movably set on the locking pin 542. The pendulum counterweight structure 541 is composed of six counterweight blocks. The six counterweight blocks can rotate around the locking pin 542 to maintain verticality to the ground, which can increase the stability of the balance bar 4; the three-axis stabilizer handle counterweight assembly 52 is based on the weight counterweight 54 and reserves the installation position of the three-axis stabilizer handle 93. The three-axis stabilizer handle 93 is used as a power supply; the V-port power supply box counterweight assembly 55 counterweight V-mount power supply clips 551 are provided on both sides, corresponding to the connection of two V-mount batteries. A series of threaded interfaces are provided around the perimeter, allowing the connection of a NATO slider 51 on either side, which in turn connects to the NATO interface 41 at one end of the balance pole 4. The Anton power supply box counterweight assembly 53 also has Anton power supply clips 531 on both sides, corresponding to the connection of two Anton batteries. A series of threaded interfaces are provided on the top, which allow the connection of a NATO slider 51, which in turn connects to the NATO interface 41 at one end of the balance pole 4. The V-mount power supply box counterweight assembly 55 and the Anton power supply box counterweight assembly 53 can adjust the relative position of the NATO slider 51 and the NATO interface 41 to achieve the effect of the pendulum counterweight structure 541 being perpendicular to the ground, thereby increasing the stability of the balance pole 4.

[0039] The control module 6 comprises a connection base 61 and a control box 62. One end of the connection base 61 is a circular tube clamp 611, which can be connected to the curved arm connector 45 of the balance bar 4 and secured with a hand-tightened screw 612. The other end is a slot 613, which can be connected to the monitor expansion slide 71 of the expansion module. A cold shoe mount is located in the middle of the connection base 61, serving as the mounting location for the control box. The control box 62 includes a joystick 621, a handwheel 624, a button 622, a replaceable battery 623, and a cold shoe mounting interface 625. The joystick 621 controls the three-axis stabilizer 92 of the photographic equipment, the handwheel 624 controls the focus motor, and the button 622 adjusts the control mode. The cold shoe mounting interface 625 connects to the cold shoe mount in the middle of the connection base 61.

[0040] The expansion module includes a monitor expansion slide 71 and a back expansion slide 72. The monitor expansion slide 71 has a series of threaded connectors and a cold shoe connector on its upper end, allowing it to connect to a camera monitor 91 or other device. Its lower end is a slider that connects to the control module's connection base 61 and can be slid back and forth to adjust its position. The back expansion slide 72 has a long hole in its middle, allowing screws to pass through the hole and connect to the camera. The back expansion slide 72 connects to the middle expansion slide seat 13 of the waist belt 1, effectively balancing the weight of the camera equipment and reducing the user's burden.

[0041] The safety mechanism includes a device protection frame 81 and a safety rope 82. The device protection frame 81 is a hollow, cylindrical tube with slide bars at each end. These slide bars connect to the left or right safety frame quick-install mounts 15, 16 of the waist belt 1. This secures the camera equipment mounted on the back extension slide, preventing damage to the equipment caused by collisions in the user's blind spot. The safety rope 82 clips into the rope buckle 18 of the waist belt 1, securing the user and providing protection during hazardous work.

[0042] The beneficial effects of the present invention are that, compared to the prior art, in the present invention, the user carries the carrying mechanism on their back, preferably at the waist, with the three-axis stabilizer supported by an extension arm and a balancing mechanism, eliminating the need for hand-held support. Furthermore, the extension arm rotates on the carrying mechanism to adjust its tilt angle, enabling the device to distribute the weight of the photographic equipment appropriately, allowing the user to more effectively bear the weight of the device and other photographic equipment while carrying the device, thereby increasing working time. Furthermore, the adjustable position of the extension arm facilitates the adjustment of the spatial position of the three-axis stabilizer relative to the user, allowing the user to use the device in a variety of different environments.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
