[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood in specific circumstances. Multiple technical solutions in the same embodiment, as well as multiple technical solutions in different embodiments, can be arranged and combined to form new technical solutions without contradictions or conflicts, all within the scope of protection required by the utility model.

[0035] Most of the gimbals in the known technology set a power controller with a circuit on a rotating platform. Using the gimbal during charging will cause the wire of the power controller to be entangled on the gimbal. To solve the problem of wire winding of the gimbal, the power controller with the circuit can be placed on a fixed base. In this case, the gimbal solves the problem of wire winding, but it causes the problem that the upper and lower circuits of the fixed base and the rotating platform cannot be normally connected. To solve the above problem, the present application provides a gimbal, which sets a power controller with a circuit on a fixed base and uses a wireless charging device, which not only solves the problem of wire winding, but also ensures that the circuits on the fixed base and the rotating platform can be connected.

[0036] like Figure 1 As shown, a platform provided in an embodiment of the present application includes: a wireless charging device, a fixed base 4, a rotating platform 5, a bearing 6, a gimbal controller 7, and a power supply controller 8.

[0037] The wireless charging device includes a transmitting coil 1 , a receiving coil 2 , and a charging controller 3 .

[0038] The wireless charging device is mainly divided into two parts, a transmitting coil 1 and a receiving coil 2. The transmitting coil 1 and the receiving coil 2 are placed in the inner ring of the bearing 6. The wireless charging device is designed using the space in the inner ring of the bearing 6. The transmitting coil 1 is fixed on the fixed base 4, and the receiving coil 2 is fixed on the bottom of the rotating platform 5, rotating with the rotating platform 5, and the transmitting coil 1 and the receiving coil 2 meet the preset distance conditions to ensure that the wireless charging device can be powered on normally, which can be a distance of several millimeters to several centimeters. Since the wireless charging device uses the space in the inner ring of the bearing 6, the size of the space in the inner ring of the bearing and the height of the bearing 6 should be comprehensively considered. It should be noted that the transmitting coil 1 and the receiving coil 2 can also be set on the outside of the bearing 6, but compared with being set in the inner ring space of the bearing 6, setting them on the outside of the bearing 6 will increase the cost of the gimbal of the present application.

[0039] It should be noted that the principle of the wireless charging device is electromagnetic induction, and energy is coupled through the coil to achieve energy transfer. It should be noted that the charging line 14 transmits an external power supply, and the charging controller 3 receives the power and transmits it to the transmitting coil 1. After the transmitting coil 1 is energized, an alternating magnetic field is generated, and it is coupled to the receiving coil 2 through the magnetic core 13, and an induced current is generated to power other devices on the rotating platform. In this process, an alternating magnetic field is generated. It should be noted that there should be no extra metal conductors near the transceiver coil of the wireless charging device, such as fixing screws, etc. If necessary, these fixing screws can be made of non-magnetic insulating materials, such as nylon, ABS (Acrylonitrile Butadiene Styrene plastic), etc., so as to avoid interfering with the wireless charging process and avoid causing additional heat loss, thereby reducing power consumption and reducing cost investment to a certain extent.

[0040] It should be noted that the wireless charging device can be a universal wireless charging device, which can not only charge the gimbal, but also charge common wireless charging devices, such as mobile phones, computers, headphones, etc. This can enhance the product competitiveness of the gimbal of the present application. Moreover, compared with the gimbal in the prior art, although the cost of wireless charging is increased, the overall cost is reduced compared with the more expensive battery.

[0041] The main frame of the pan / tilt head is a fixed base 4 and a rotating platform 5, which are connected by a bearing 6. The bearing 6 is divided into an inner ring and an outer ring. To ensure that the rotating platform can rotate, the outer ring of the bearing is fixedly connected to the rotating platform 5, and the inner ring of the bearing is fixedly connected to the fixed base 4.

[0042] The pan-tilt head also includes a motor 9, such as Figure 1As shown, the motor 9 is fixed on the rotating platform 5, and the transmission shaft 10 of the motor can be located at the rotation center of the bearing 6, and the transmission shaft 10 is fixed on the fixed base 4. This design, on the one hand, saves space, and the entire gimbal is more compact and portable, and on the other hand, can save costs to the greatest extent. It should be noted that the transmission shaft 10 is a non-magnetic material, such as aluminum alloy, nylon, etc., which can avoid interference with wireless charging and also avoid additional heat loss, thereby reducing power consumption and reducing cost investment to a certain extent. Here, the connection method between the motor 9 and the transmission shaft 10 is similar to the connection method of the electric fan in daily life. The fan blades rotate around the transmission shaft of the fan, and the transmission shaft of the fan is fixed on the fan head. Here, the fixed base 4 is equivalent to the fan blades, but the state is fixed and stationary, so the reverse thrust motor drives the rotating rotating platform 5 to rotate clockwise or counterclockwise.

[0043] The gimbal may further include a rechargeable battery 11 and a camera 12. The rechargeable battery 11 is fixed on the rotating platform 5 and may be a lithium battery or other types of storage batteries for storing electricity so that the gimbal does not need to be plugged in and can be used directly after the battery is fully charged. In order to further reduce costs, the rechargeable battery 11 may also be omitted, but it can only be used under external continuous power supply.

[0044] The camera 12 is also fixed on the rotating platform 5 for collecting target images. At this time, the gimbal can be used as a face tracking gimbal. It should be noted that the face tracking gimbal mainly adopts face recognition technology. Based on the position of the face in the image, it automatically links with the electric gimbal to keep the face at the best angle and realize intelligent face tracking of the gimbal. Nowadays, with the continuous development of AI (Artificial Intelligence) technology and semiconductor technology, the cost of face recognition is very low. There are many electric gimbals on the market that can realize automatic face tracking. For example, during live broadcast, this face tracking gimbal can track faces throughout the whole process, so that netizens who watch the live broadcast can always watch the live broadcast at the best angle; it can also be used in exhibition halls to make the display cabinet automatically face the display items to the visitors.

[0045] Optionally, the gimbal also includes a magnetic core 13, and the gimbal includes a wireless charging device. The magnetic core 13 is arranged on the outside of the transmission shaft 10 of the motor, which can improve the efficiency of current transmission between the transmitting end and the receiving end of the wireless charging device. The magnetic core 13 can also be divided into two upper and lower parts along with the upper and lower coils. Wireless power supply can be achieved as long as they are close to each other.

[0046] Optionally, the transmission shaft 10 of the motor 9 can also be located on the outside of the bearing 6, and can be connected to the rotating platform 5 through but not limited to belts or gears and other components. It should be noted that the material of the transmission shaft 10 also needs to be non-magnetic material, such as aluminum alloy, nylon, etc., so as to avoid interference with wireless charging and also avoid additional heat loss, thereby reducing power consumption and reducing cost investment to a certain extent.

[0047] Next, the pan / tilt in the present application is compared with the pan / tilt in the prior art. Figure 2 As shown, it includes: a charging controller 3, a fixed base 4, a rotating platform 5, a bearing 6, a pan / tilt controller 7, a motor 9, a transmission shaft 10, a rechargeable battery 11, a camera 12, and a charging cable 14.

[0048] As shown in the figure, the fixed base 4 and the rotating platform 5 are connected by a bearing, and the bearing 6 is divided into an inner ring and an outer ring. To ensure that the rotating platform can rotate, the outer ring of the bearing is fixedly connected to the rotating platform 5, and the inner ring of the bearing is fixedly connected to the fixed base 4. The charging controller 3, the pan / tilt controller 7, the motor 9, the rechargeable battery 11, the camera 12 and the charging line 14 are all fixed on the rotating platform 5, and rotate with the rotating pan / tilt 5. The rechargeable battery 12 can be, but is not limited to, a lithium battery. The pan / tilt is mainly powered by a lithium battery, and the battery needs to be charged regularly to ensure the normal operation of the pan / tilt. The pan / tilt disclosed in the present application also uses the rechargeable battery 12 to store electricity, but due to the addition of a wireless charging device, the normal use of the pan / tilt will not be affected when the device is charged, and the volume of the rechargeable battery 12 used is smaller than that of the battery in the known technology, which reduces the cost of the product and can reduce the weight required to be loaded on the rotating platform 5.

[0049] It is understandable that the known technology uses wired charging to charge the battery and then achieve the purpose of battery life. On the one hand, when charging the battery, if the known technology is used to work, the charging line 14 will be entangled with the rotating platform 5, and the charging line 14 may drag the entire platform, causing the platform to be blocked from rotating and unable to work normally. In order to avoid the situation of dragging and entanglement, it may be necessary to increase the number of purchased platforms, which will greatly increase the investment cost, and the platform is inconvenient to use when charging, which will cause the corresponding work to be suspended and waited, and also increase the time cost investment, and the competitiveness of the entire platform will be greatly reduced. On the other hand, the charging controller 3, the platform controller 7, the motor 9, the rechargeable battery 11 and the camera 12 are combined together, all fixed on the rotating platform 5 and rotate with it, which will increase the weight that the rotating platform 5 needs to bear. At this time, the motor 9 needs to consume more electricity to drive the rotating platform 5 to rotate, and the power consumption of the entire platform will be further increased. In addition, the lithium battery in the known technology is large in size, high in cost, and has limited battery life, and cannot work continuously for a long time.

[0050] The circuit connection method of the pan / tilt disclosed in the present application is also different from that of the pan / tilt in the prior art. For the circuit connection of the pan / tilt disclosed in the present application, see Figure 3 As shown in the circuit connection example diagram of the gimbal provided by this application, it can be understood that the leftmost interface line is the charging line 14, which can be used to connect the power supply, the PS controller is the charging controller 3, which is used to control the circuit of the fixed base 4 for wireless charging, and the PD controller & charging controller is the power controller 8, which is used to receive the current transmitted by the transmitting coil 1 and is connected to the rechargeable battery 11 to store electricity for the battery. It is also connected to the gimbal controller 7. It can be understood that the gimbal controller 7 is the main controller shown in the figure, and the main controller is connected to the camera 12, the power controller 8 and the motor 9.

[0051] The circuit connection method of the pan / tilt disclosed in the present application is specifically to connect the power source through the interface of the charging line, which can be but not limited to the USB interface. The power source can be but not limited to the socket, power bank, etc. After the power source is turned on, the current is connected to the PS (Power source) controller, corresponding to Figure 1 The charging controller 3 in the transmitter coil 1 generates a magnetic field after the transmitter coil 1 is energized, and the receiver coil 2 generates an induced current. Figure 3 In the PD controller & charging controller, it corresponds to Figure 1 The power controller 8 in the PD controller and the charging controller then deliver the current to the rechargeable battery 11 and the main controller respectively. The main controller corresponds to Figure 1The pan-tilt controller 7 is connected to the camera 12 and the motor 9, that is, the current can be transmitted to the camera 12 and the motor 9 through the main controller to ensure the stable operation of each component. The main controller can control the operation of the camera 12 and the motor 9 through buttons.

[0052] For the circuit connection of the pan / tilt in the known technology, see Figure 4 The circuit connection example diagram of the pan / tilt in the known technology shown in the figure is different in that there is an additional power controller 8 in the present application. The reason for the difference is that the present application adopts a wireless charging device, and different controllers need to be set for the transmitting coil and the receiving coil respectively. Figure 1 and Figure 2 Compared with the gimbal in the known technology, the charging controller in the gimbal disclosed in the present application is fixed on the fixed platform 4. At the same time, the battery 11 is replaced with a smaller battery. Compared with the face tracking gimbal in the known technology, the weight that the rotating platform 5 needs to bear is reduced, so that the motor 9 only needs to consume relatively low electric energy to drive the rotating platform 5 to achieve the corresponding rotation to work, which reduces the use of electricity to a certain extent and improves the competitiveness of this product to a certain extent.

[0053] In summary, the gimbal disclosed in the present application. By setting a wireless charging device as the current transfer between the fixed base 4 and the rotating platform 5, the transmitting coil 1 of the wireless charging device is fixed on the fixed base 4, the receiving coil 2 is fixed on the bottom of the rotating platform 5, and the transmitting coil 1 and the receiving coil 2 are placed in the inner ring space of the bearing 6, and the transmitting coil 1 is connected to the power controller 3 fixed on the fixed base. After the wireless charging device is set, the face tracking gimbal can be continuously powered, and there will be no problem of being dragged by the charging cable and the gimbal rotation being blocked and malfunctioning.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
