Description

Technical Field

[0001] This invention relates to the field of camera equipment technology, and in particular to a three-axis gimbal shooting device. Background Technology

[0002] A gimbal-mounted shooting device is a shooting device equipped with a gimbal. Most existing three-axis gimbal-mounted shooting devices use a gimbal as disclosed in invention patent application number CN2020101220413. This gimbal includes a first rotating bracket for controlling movement around the translation / yaw axis, a second rotating bracket rotatably connected to the first rotating bracket for controlling movement around the roll axis, and a third rotating bracket rotatably connected to the second rotating bracket for controlling movement around the pitch axis. The three axes, from bottom to top, are YAW (yaw axis) - ROLL (roll axis) - PITCH (pitch axis). The second drive device in the second rotating bracket for controlling the roll axis movement is connected to the third rotating bracket... The second support, roughly Y-shaped, is connected to the camera, while the third drive unit, which controls the movement around the pitch axis, is connected to one side of the second support. The other side of the second support supports the camera, and the camera lens is independent of the drive unit. This results in a large overall camera module size, which will become increasingly uncompetitive in today's trend of miniaturizing products. Furthermore, with this three-axis setup, after the second drive unit controls the camera to switch between horizontal and vertical shooting modes, the third drive unit cannot move the camera in the pitch direction, but can only rotate it in the horizontal direction. The three-axis gimbal becomes a single-axis gimbal, lacking multi-axis variation effects and functional deficiencies, which affect the user experience and cause the product to lose some of its competitiveness. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a three-axis gimbal shooting device with a small overall size and good shooting effect.

[0004] To address the aforementioned technical problems, this invention provides a three-axis gimbal imaging device, comprising a camera module and a gimbal module, wherein...

[0005] The camera module includes a lens barrel and a lens module installed inside the lens barrel;

[0006] The gimbal module includes:

[0007] A support arm mechanism includes a base and a support arm located above the base to support the camera module;

[0008] A yaw axis motor is installed inside the base, with its rotor extending out of the base and connected to the support arm to drive the support arm to rotate;

[0009] A pitch axis motor is installed at the upper end of the support arm, and its rotor is connected to the middle of the side wall of the lens barrel to drive the lens barrel to rotate.

[0010] A roll shaft motor is installed at the rear end of the lens barrel. The roll shaft motor contacts the rear end cover of the lens barrel and is fixedly installed on the inner wall of the rear end cover. Its rotor is connected to the lens module to drive the lens module to rotate.

[0011] The beneficial technical effects of this invention are as follows: Compared with the prior art, in the three-axis gimbal shooting device of this invention, the rotor of the pitch axis motor installed at the upper end of the support arm is connected to the middle of the side wall of the lens barrel to drive the lens barrel to rotate. The roll axis motor is installed at the rear end inside the lens barrel, integrating the roll axis motor into the lens barrel. The lens barrel can simultaneously protect the lens and the roll axis motor. The rotor of the roll axis motor is connected to the lens module inside the lens barrel, driving the lens module to rotate. Therefore, the three axes in this invention are designed in the order of YAW (yaw axis) - PITCH (pitch axis) - ROLL (roll axis) from bottom to top. The camera module and support arm can form a cantilever structure. Compared with traditional gimbal cameras, the size is reduced in the product-sensitive camera optical axis direction. At the same time, no connecting mechanisms are needed on both sides of the camera module, resulting in a smaller overall size. Small and easy to carry and store, the roll axis motor drives the lens module to switch between horizontal and vertical shooting modes, while the pitch axis motor still has a pitch function. Combined with the normally operating yaw axis motor, a wider shooting range and better tracking shooting effect can be obtained. Furthermore, in this invention, when the roll axis motor enters the lens barrel, it contacts and is fixed to the rear end cover of the lens barrel. Its rotor is connected to the lens module, so the heat generated by the lens module inside the lens barrel can be conducted to the rear end cover of the lens barrel through the roll axis motor, and then dissipated to the outside through the rear end cover of the lens barrel. This dissipates the heat generated by the lens module in the form of transfer, thereby avoiding the accumulation of heat inside the lens barrel, which can cause severe overheating or local overheating and damage to internal components. Therefore, the three-axis gimbal shooting device of this invention is not only small in overall size and has a good shooting effect, but also has heat dissipation, which can further improve the user experience.

[0020] To better understand the technical content of this invention, the technical solution of this invention will be further introduced and explained below with reference to the schematic diagram, but it is not limited thereto.

[0021] Reference Figures 1 to 8 , Figures 1 to 8A specific embodiment of the three-axis gimbal shooting device 100 of the present invention is shown. In the embodiment shown in the figures, the three-axis gimbal shooting device 100 includes a camera module 10 and a gimbal module 20. The camera module 10 includes a lens barrel 11 and a lens module 12 installed inside the lens barrel 11. The gimbal module 20 includes a support arm mechanism 21, a yaw axis motor 22, a pitch axis motor 24, and a roll axis motor 23. The support arm mechanism 21 includes a base 210 and a support arm 211 located above the base 210 to support the camera module 10. The yaw axis motor 22 is installed inside the base 210, and its rotor extends out of the base 210 and is connected to the support arm 211. The camera module 10 is yaw controlled by connecting the support arm 211 to drive its rotation. The pitch axis motor 24 is mounted on the upper end of the support arm 211, and its rotor is connected to the middle of the side wall of the lens barrel 11 to drive the lens barrel 11 to rotate and achieve pitch control of the camera module 10. The roll axis motor 23 is mounted on the inner rear end of the lens barrel 11. The roll axis motor 23 contacts the rear end cover 115 of the lens barrel 11 and is fixedly mounted on the inner wall of the rear end cover 115. Its rotor is connected to the lens module 12 to drive the lens module 12 to rotate and achieve roll control of the camera module 10. Based on the above design, the three axes of the three-axis gimbal shooting device 100 of the present invention are arranged in the following order from bottom to top: YAW (yaw axis) - PITCH (pitch axis) - ROLL (roll axis). The camera module 10 and the support arm 211 can form a cantilever structure, and the roll axis motor 23 is integrated into the lens barrel 11. The lens barrel 11 can protect the lens module 12 and the roll axis motor 23. Compared with traditional gimbal cameras, the size in the optical axis direction of the camera is reduced, and there is no need to set up connecting mechanisms on both sides of the camera module 10, resulting in a smaller overall size. Furthermore, after the roll axis motor 23 drives the lens module 12 to switch between horizontal and vertical shooting modes (from horizontal shooting mode to vertical shooting mode or from vertical shooting mode to vertical shooting mode), the overall size is smaller. In landscape shooting mode, the pitch axis motor 24 still has a pitch function. Combined with the normally operating yaw axis motor 22, the shooting range is wider and better tracking shooting effect can be obtained. In addition, in this invention, when the roll axis motor 23 enters the lens barrel 11, it contacts and fixes itself to the rear end cover 115 of the lens barrel 11. Its rotor is connected to the lens module 12. The heat generated by the lens module 12 in the lens barrel 11 can be conducted to the rear end cover 115 of the lens barrel 11 through the roll axis motor 23, and then dissipated to the outside through the rear end cover 115. The heat generated by the lens module 12 can be dissipated in the form of transfer, thereby avoiding the accumulation of heat in the lens barrel 11, which may cause severe overheating or local overheating and damage to internal components.

[0022] In some embodiments, such as Figure 2As shown, the support arm 211 includes a support base 2111 and a support arm 2112 extending upward from the side of the top plate of the support base 2111. The upper part of the support arm 2112 is connected to a pitch axis motor mount 2113 for mounting the pitch axis motor 24. The pitch axis motor mount 2113 is also covered with a motor cover 2114. The pitch axis motor mount 2113 communicates with the support arm 2112 and the support base 2111. The rotor of the yaw axis motor 22 extends out of the base 210 and connects to the support base 2111, so that the support base 2111 is connected to the top of the base 210 through the pitch axis motor 24.

[0023] Preferably, the gimbal module 20 further includes a control component located within the support arm mechanism 21. This control component includes a Wi-Fi board assembly 251 and a main board 252. The yaw axis motor 22, pitch axis motor 24, and roll axis motor 23 are controlled by the Wi-Fi board assembly 251. The main board 252 is electrically connected to the Wi-Fi board assembly 251 and the lens module 12. The Wi-Fi board assembly 251 and the main board 252 are located above and below the yaw axis motor 22, respectively. The Wi-Fi board assembly 251 is close to the yaw axis motor 22 so that the heat generated by the Wi-Fi board assembly 251 can be conducted to the yaw axis motor 22. Since the motor is generally a metal motor, the heat can be transferred through the metal yaw axis motor. The roll axis motor 22 provides auxiliary heat dissipation. In this embodiment, the gimbal module also includes a main coaxial line 13. The lens module 12 includes a lens assembly 122 and a sensor plate 121. The sensor plate 121 is installed at the rear end of the lens assembly 122. The main coaxial line 13 is led out from the sensor plate 121 of the lens module 12, passes through the roll axis motor 23, and is attached to the inner side wall of the lens barrel 11 to be introduced into the pitch axis motor 24. It then passes through the pitch axis motor seat 2113, the support arm 2112, the support seat 2111, and the shaft of the yaw axis motor 22 in sequence before entering the base 210 and connecting with the main board 252, so that the main board 252 is electrically connected to the lens module 12. Specifically, the Wi-Fi board 251 has a second coaxial cable leading out, which passes through the yaw axis motor 24 and enters the base 210 to connect with the main board 252. In this invention, the Wi-Fi board 251 is controlled by the main board 252 and can also be used to receive information from the main board 252 to control the gimbal module 20. It is directly connected to the ESC board of the yaw axis motor 22 and the ESC board 242 of the pitch axis motor 24 to control the yaw axis motor 22 and the pitch axis motor 24. The Wi-Fi board 251 can also be used as a relay for external information streaming or transmission and reception, and may include 2.4G and / or 5G frequency bands.

[0024] In this embodiment, the ESC board 233 of the roll axis motor 23 is electrically connected to the SENSOR board 121 via an FPC connector, and the Wi-Fi board assembly 251 also communicates with the SENSOR board 121 via a serial port to indirectly control the roll axis motor 23. Based on the above design, the Wi-Fi board assembly 251, the main board 252, and the SENSOR board 121 are interspersed among the motor structure, resulting in a clear hardware layout. This design makes reasonable use of the internal space of the three-axis gimbal shooting device 100, greatly reducing the product size.

[0025] To enhance the signal stability of the Wi-Fi board 251 and reduce signal interference, in this embodiment, the antenna of the Wi-Fi board 251 is disposed on the outer surface of the support arm to reduce interference from components within the support base 2111 and the base 210 on antenna testing. Specifically, the number of antennas can be adjusted according to actual needs, such as... Figure 7 As shown, in this embodiment, there are two antennas. One antenna is laser-engraved in a first region 2511 on the outer surface of the support arm 2112, and the other antenna is laser-engraved in a second region 2512 on the outer surface of the support base 2111. It is understood that in some other embodiments, the two antennas may also be fixed inside the support arm 211, for example, both fixed to the inner surface of the support base 211, and they can also transmit signals.

[0026] Continue to refer to Figure 2 and Figure 6 In some embodiments, the three-axis gimbal shooting device 100 further includes a heat dissipation component, which includes a metal adapter 31. The motherboard 252 is mounted on the metal adapter 31. The metal adapter 31 is located inside the base 210 and its top end is close to the yaw axis motor 22, and is fixed to the yaw axis motor 22 by screws.

[0027] Specifically, in this embodiment, the bottom of the base 210 is covered with a bottom cover 212 made of metal material. The metal adapter 31 includes a mounting plate 311, which contacts the inner wall of the base 210. In this embodiment, the upper surface of the mounting plate 311 contacts the inner upper surface of the base 210, and a plurality of support feet 312 are formed on the lower surface of the mounting plate 311. The main board 252 is located below the mounting plate 311 and on the lower surface of the plurality of support feet 312, so as to allow the plurality of support feet to pass through. 312 is fixed and close to the bottom cover 212, and the space between the main board 252 and the bottom cover 212 is filled with thermally conductive material. The upper surface of the base 210 is provided with screw holes 2100. The screws pass through the mounting plate 311, the screw holes 2100 on the upper surface of the base 210 and the yaw axis motor 311 in sequence, so that the metal adapter 31 is locked on the yaw axis motor 311 and suspended in the base 210. Understandably, in order to accelerate heat dissipation, thermally conductive solder paste can also be pasted between the main board 252 and the support foot 312. Based on the above design, the motherboard 252 has the highest temperature rise when the three-axis gimbal shooting device 100 is working. The heat generated by the motherboard 252 can be conducted through the metal adapter 31. On the one hand, the heat is transferred to the side and downward to the base 210 and the bottom cover 212 respectively, and dissipated to the outside through the base 210 and the bottom cover 212. On the other hand, the heat is transferred upward to the yaw axis motor 22, and the metal yaw axis motor 22 provides auxiliary heat dissipation to accelerate the heat transfer and prevent the base 210 from overheating due to heat accumulation, which could damage the internal components.

[0028] To enhance the strength of the metal adapter 31, a barrier 313 extends upward from the edge of the upper surface of the mounting plate 311, providing more support for the metal adapter 31 in three-dimensional space. Furthermore, a reinforcing rib 314 is formed between the two support legs 312, resulting in higher overall strength.

[0029] Furthermore, the three-axis gimbal shooting device 100 also includes a battery 50 that powers the device. The battery 50 is located within the base 210 and above the mainboard 252, and is glued to the mounting plate 311 below it using foam adhesive. A battery protection plate 51 on the battery 50 is positioned between the two support feet 312 of the metal adapter 31 to fully limit the battery 50 and prevent the heat generated by the battery 50 and the mainboard 252 from affecting each other. The battery protection plate 51 and the support feet 312 are insulated to provide electrostatic protection. Preferably, in some other embodiments, the heat dissipation assembly may also include a heat insulation component made of heat-insulating material, disposed between the mainboard 252 and the battery 50 to further prevent the heat generated during operation from affecting each other.

[0030] Preferably, in some other embodiments, the three-axis gimbal shooting device 100 may further include an electrostatic protection component, which includes a metal spring pin, through which the main board 252 contacts the bottom cover 212; and / or includes electronic wires. In this embodiment, the main coaxial line 13 is connected to the lens module 12 through a main coaxial line socket, and the coaxial line socket is connected to the stator flying wire of the roll axis motor 23 through the electronic wires, so that the roll axis motor 23 and the SENSOR board 121 in the lens module 12 are grounded and connected, thereby achieving electrostatic protection.

[0031] Continue to refer to Figure 2 and Figure 8 In some embodiments, the gimbal module 20 further includes an expansion interface component, which includes a connection board 255. The lower surface of the connection board 255 is provided with two rows of PIN pins 2551 that are electrically connected to the motherboard 252 (e.g., ...). Figure 8 As shown, the bottom cover 212 has two first slots 2120. The connecting plate 255 is fixed to the bottom cover 212 and makes contact with the bottom cover 212, which is made of metal, to achieve electrostatic protection. Two rows of PIN pins 2551 pass through the two first slots 2120 respectively. The bottom cover 212 also has two second slots 2121 for connecting with external expansion accessories. Preferably, in this embodiment, the two second slots 2121 are located outside the two first slots 2120 respectively. In this invention, the PIN pins 2551 can serve as external expansion interfaces for the three-axis gimbal shooting device 100. The three-axis gimbal shooting device 100 can be charged through the contacts of the PIN pins 2551, and bidirectional serial communication can also be performed.

[0032] Furthermore, such as Figure 2 As shown, the expansion interface component also includes a magnet 60, which may be U-shaped. The magnet 60 is located below the motherboard 252 and fixed to the bottom cover 212. Understandably, the magnet 60 can be a single, integrated magnet or composed of multiple small magnets connected end-to-end. During use, it can be magnetized symmetrically from left to right, or directionally magnetized as needed to strengthen the magnetism in a specific direction. Furthermore, magnetic conductive sheets can be placed on the poles of the magnet 60 after magnetization to increase the magnetic force, giving the bottom cover 212 a stronger magnetic attraction, allowing it to connect magnetically with external expansion devices for cooperative operation.

[0033] Continue to refer to Figures 2 to 5Specifically, the lens barrel 11 includes a housing 114 and a rear end cover 115 disposed at the rear end of the housing 114. In this embodiment, a motor connection position 110 is formed in the middle of the side wall of the housing 114. The rotor of the pitch axis motor 24 is located at the motor connection position 110 and connected to the housing 114. The stator of the roll axis motor 23 is fixed to the inner wall of the rear end cover 115. Specifically, the rear end cover 115 is integrally formed with the housing 11. A plurality of mounting ears 232 are formed on the outer peripheral wall of the roll axis motor 23 near the end of the rear end cover 115. The stator of the roll axis motor 23 is locked to the inner wall of the rear end cover 115 by screws passing through the mounting ears 232. The lens assembly 122 is installed at the front end of the housing 114, and the sensor plate 121 faces the roll axis motor 23. The rotor of the roll axis motor 23 is connected to the sensor plate 121. A cable constraint cavity 112 for accommodating the main coaxial cable 13 is formed between the inner side wall of the housing 114 and the side wall of the roll axis motor 23 along the direction from the inner rear end of the housing 114 to the motor connection position 110, so as to limit the main coaxial cable 13. Thus, through the cable constraint cavity 112, the main coaxial line 13, extending from the sensor plate 121 of the lens module 12 and passing through the shaft of the roll axis motor 23 before entering the housing 114, can be constrained and positioned via the cable constraint cavity 112 before being introduced into the pitch axis motor 24. This effectively fixes the main coaxial line 13 between the roll axis motor 23 and the pitch axis motor 24, preventing interference with internal components of the housing 114 when the roll axis motor 23 rotates, thus avoiding impact on the normally operating lens module 12. It also reduces the torque effect of the main coaxial line 13, ensuring the operational stability of the three-axis gimbal shooting device 100. In some embodiments, a decorative ring 1141 is fitted at the front end of the lens barrel 11, and a lens is mounted on the decorative ring 1141; a metal decorative piece is fitted at the rear end of the lens barrel 11. Specifically, the decorative ring 1141 is fitted at the front end of the housing 114, and a lens is provided on the top cover of the decorative ring 1141 to close the front end of the housing 114. The metal decorative piece is fitted at the rear end of the housing 114 to close the rear end of the housing 114. The lens and the metal decorative piece serve to prevent dust and dirt, and also make the equipment more aesthetically pleasing.

[0034] Continue to refer to Figure 3 , Figure 4 and Figure 5In this preferred embodiment, the motor connection position 110 includes a connection position opening 1100 formed on the side wall of the housing 114, a connection position enclosure 1101 extending outward around the connection position opening 1100, and an annular connecting plate 1102 disposed at the inner end face of the connection position enclosure 1101. The rotor of the pitch axis motor 24 is connected to the annular connecting plate 1102 to drive the lens barrel 11 to rotate, thereby realizing the pitch operation of the lens module 12 installed inside the lens barrel 11.

[0035] Understandably, the three-axis gimbal shooting device 100 of the present invention can be charged and communicate bidirectionally via a serial port through the exposed PIN pin 2551. After the PIN pin signal is transmitted to the motherboard 252, the motherboard 252 processes the signal. During operation, the motherboard 252 sends control commands to the Wi-Fi board 251, which can directly control the rotation of the yaw axis motor 22. The rotor of the yaw axis motor 22 drives the support arm 211 to rotate, completing the yaw action of the gimbal. At the same time, it can also send commands to the ESC board 242 of the pitch axis motor 24 to control the rotor of the pitch axis motor 24 to rotate, driving the housing 114 to rotate, completing the pitch action of the gimbal. It can also send control commands to the SENSOR board 121, so that the SENSOR board 121 sends control commands to the ESC board 233 of the roll axis motor 23, thereby controlling the rotor of the roll axis motor 23 to rotate. Since its rotor is connected to the lens module 12, it can drive the lens to rotate to complete the roll action of the gimbal, thereby shooting.

[0036] Continue to refer to Figure 2 In some embodiments, the three-axis gimbal shooting device 100 further includes a button board 80 and an LED light board 71 connected to the motherboard 252, and may also include four microphone components. The four microphone components are disposed within the base 210 and are electrically connected to the motherboard 252 through the button board 80. The button board 80 can be used to perform operations such as powering on and off the three-axis gimbal shooting device 100. The button board 80 and the LED light board 71 can be located on opposite sides of the base 210. The buttons on the button board 80 are exposed outside the base 210. A light guide plate 72 is also sleeved on the outer side of the LED light board 71. The light guide plate 72 has a light guide post 721 corresponding to each LED bead of the LED light board 71, and the LED bead extends into the light guide post 721. The outer end of the light guide post 721 is exposed outside the base 210 to control and guide the light, so that the light emitted by the LED bead is emitted outward through the light guide post 721 for battery power display, thereby prompting the user.

[0037] In summary, the three axes of this invention's three-axis gimbal shooting device are designed in the following order from bottom to top: YAW (yaw axis) - PITCH (pitch axis) - ROLL (roll axis). The camera module and support arm can form a cantilever structure, and the roll axis motor is integrated into the lens barrel, which protects the lens module and the roll axis motor. Compared to traditional gimbal cameras, the size is reduced along the camera's optical axis, and no connecting mechanisms are needed on either side of the camera module, resulting in a smaller overall size. Furthermore, after the roll axis motor drives the lens module to complete the horizontal / vertical shooting mode switch, the pitch axis motor still has pitch functionality. Combined with the normally functioning yaw axis motor, this allows for a wider shooting range and better tracking shooting effects. Furthermore, the heat generated inside the three-axis gimbal shooting device of this invention can also be dissipated through transfer. That is, the heat generated by the lens module inside the lens barrel can be conducted to the rear end cover of the lens barrel through the roll axis motor, and then dissipated outward through the metal rear end cover. The heat generated by the motherboard can be conducted through the metal adapter. On the one hand, it is transferred to the base and bottom cover through the mounting plate and support feet of the metal adapter, and then dissipated outward through the base and bottom cover. On the other hand, it is transferred to the yaw axis motor for heat dissipation through screws. In addition, a heat insulation component is also provided between the motherboard and the battery to avoid the heat generated by the motherboard from affecting the battery. This device can meet the requirements of heat dissipation while satisfying the miniaturization of the product, thereby improving the user experience.

[0038] The above preferred embodiments should be regarded as illustrative examples of the implementation of the present invention. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present invention should be considered within the scope of protection of this patent.
