[0023] The gimbal is a supporting device for installing and fixing mobile phones, cameras, and camcorders. It is divided into fixed and electric gimbals. The gimbal can be rotated at will, and generally has horizontal and vertical rotation functions, which is convenient for users to take photos or shoot. However, the gimbal products on the market have a lot of operating noise. The noise will be transmitted to the mobile device through the gimbal structure. After being recorded and amplified by the microphone of the mobile device, the video / audio works will have a lot of background noise, affecting the user experience.

[0024] In order to solve the above technical problems, the present application provides an intelligent pan-tilt head, including a bracket mechanism, a pitch mechanism and a limit mechanism. Among them, a silencer structure is arranged on the bracket mechanism, which can reduce the noise generated during the operation of the intelligent pan-tilt head. The pitch mechanism includes a pitch motor and a motor bracket. A gap is arranged between the housing of the pitch motor and the motor bracket, which can isolate the vibration and the noise transmission path, and further reduce the noise generated during the operation of the intelligent pan-tilt head. The limit mechanism includes an adapter block and a touch switch. When the pitch of the bracket mechanism reaches a certain angle, the adapter block triggers the touch switch to generate a pitch in place signal to stop the pitch of the bracket mechanism. Compared with the conventional use of a physical limit structure for limiting, this process avoids the relatively large vibration and current noise caused by frequent motor stalling, and further reduces the noise generated during the operation of the intelligent pan-tilt head.

[0025] like Figure 1 As shown, the intelligent gimbal includes a support mechanism, a pitch mechanism and a limit mechanism, wherein the support mechanism is used to place a mobile device, the support mechanism is provided with a muffler structure, the muffler structure is used to reduce the noise generated when the intelligent gimbal is in operation, the pitch mechanism is used to control the support mechanism to achieve a pitch action, the pitch mechanism includes a pitch motor 4 and a motor bracket 5, a gap is provided between the housing of the pitch motor 4 and the motor bracket 5, for isolating the noise generated when the intelligent gimbal is in operation, the limit mechanism is used to achieve the pitch limit of the support mechanism, the limit mechanism includes a transfer block and a touch switch, when the pitch of the support mechanism reaches a certain angle, the transfer block triggers the touch switch to generate a pitch in place signal, and the pitch in place signal plays a role in limiting the support mechanism. Wherein, there is no other contact between the housing of the pitch motor 4 and the motor bracket 5 except for the screw contact position.

[0026] As one of the implementation methods, Figure 1 and Figure 2 As shown, the bracket mechanism includes an upper shell 2 and a clamping structure 3, wherein the clamping mechanism 3 is used to clamp a mobile device, and the clamping mechanism 3 is connected to the upper shell 2 through a support rod 301, and a wiring space is formed between the support rod 301 and the upper shell 2; the upper shell 2 is provided with a sink 205, and the sink 205 is a structure that is recessed into the inside of the intelligent gimbal, and the recessed part forms a wiring space; the upper shell 2 is provided with a wire-hiding groove 201, and the charging cable of the mobile device can be hidden in the wire-hiding groove 201 through the wiring space. Preferably, the number of the support rods 301 is 4, and the support rods 301 can reduce the contact area between the clamping mechanism 3 and the upper shell 2, which is conducive to reducing the vibration and noise generated when the intelligent gimbal is working.

[0027] As one of the embodiments, the bottom of the wire storage groove 201 is provided with the muffler structure, which includes a muffler hole 202 and a soft glue 203 for blocking the muffler hole 202. The muffler hole 202 can change the natural frequency of the upper shell, avoid forming a closed cavity, and avoid resonance with the motor operating frequency to cause noise amplification. The muffler hole 202 is blocked with a soft glue 203, which can absorb resonance energy and reduce noise peaks.

[0028] As one of the implementation methods, refer to Figure 3 and Figure 4 The pitch mechanism also includes a pitch driving gear 6, which is coaxially mounted on the output shaft of the pitch motor 4. The pitch driving gear 6 is meshed with a pitch passive gear 204 fixedly arranged on the bracket mechanism, thereby driving the bracket mechanism to achieve a pitch action. The pitch driving gear 6 is meshed with the pitch passive gear 204 in an internal meshing manner, which can save space and has lower noise.

[0029] As one embodiment, the pitch mechanism further includes a first bearing 7, the outer ring of the first bearing 7 is coaxially mounted on the pitch driving gear 6, and the inner ring of the first bearing 7 is coaxially mounted on a support frame 8 provided on the motor bracket 5. The support frame 8 can avoid a single cantilever force structure, ensuring that the pitch driving gear 6 is evenly stressed when meshing with the pitch passive gear 204.

[0030] As one embodiment, the support frame 8 includes a guide rail 801 and a first bearing assembly position 802. The support frame 8 is fixed by sliding into a guide groove 501 provided on the motor bracket 5 through the guide rail 801, and the first bearing assembly position 802 is inserted into the inner ring of the first bearing 7. The guide rail 801 and the guide groove 501 structure facilitate assembly.

[0031] As one of the implementation methods, refer to Figure 3 The adapter block includes a first adapter block 9 and a second adapter block 10, wherein the first adapter block 9 is assembled on the motor bracket 5 through a second bearing 904, and the second adapter block 10 is assembled on the motor bracket 5 through a third bearing 102. The first adapter block 9 is coaxially sleeved on the outer ring of the second bearing 904, and the inner ring of the second bearing 904 is coaxially sleeved on the second bearing assembly position 505 of the motor bracket 5. The second adapter block 10 is coaxially sleeved on the outer ring of the third bearing 102, and the inner ring of the third bearing 102 is coaxially sleeved on the third bearing assembly position 506 of the motor bracket 5. The first adapter block 9 and the second adapter block 10 are fixedly connected to the bracket mechanism. When the pitch mechanism controls the pitch of the bracket mechanism, the bracket mechanism drives the first adapter block 9 and the second adapter block 10 to rotate. After the adapter block is assembled on the motor bracket 5 through the bearing, it is fixed to the motor bracket through screws on the one hand, and fixed to the bottom of the upper shell 2 through screws on the other hand.

[0032] As one of the implementation methods, refer to Figure 3 and Figure 5 , the first adapter block 9 is provided with a front cantilever 901 and a rear cantilever 902. When the pitch of the bracket mechanism reaches a certain angle, the front cantilever 901 triggers the first touch switch 503 provided on the motor bracket 5 to generate a forward leaning signal or the rear cantilever 902 triggers the second touch switch 504 provided on the motor bracket 5 to generate a backward leaning signal, wherein the touch switch includes a first touch switch 503 and a second touch switch 504. It should be noted that when a forward leaning signal is generated, the intelligent gimbal stops leaning forward, and when a backward leaning signal is generated, the intelligent gimbal stops leaning backward. Compared with the conventional physical limit structure, this process avoids the relatively large vibration and current noise caused by frequent motor stalling, and greatly reduces the noise generated during the operation of the intelligent gimbal. Preferably, the second adapter block 10 does not need to be provided with a front cantilever and a rear cantilever to reduce structural complexity and cost.

[0033] As one of the implementation methods, refer to Figure 3 and Figure 6, both sides of the first adapter block 9 and the second adapter block 10 are provided with limiting ribs 903 (the limiting ribs of the second adapter block 10 are not shown in the figure), and the limiting ribs 903 cooperate with the limiting ribs 502 arranged at the corresponding position of the motor bracket 5 to play a physical limiting role on the bracket mechanism, wherein the limiting fan-shaped interval range of the limiting ribs is larger than the pitch limiting range controlled by the touch switch, that is, under normal circumstances, when the intelligent gimbal is about to over-pitch, the touch switch is triggered first. If the intelligent gimbal continues to pitch for some reason, the limiting ribs play a role and perform physical limiting to avoid the risk of the intelligent gimbal tipping over due to excessive tilt angle.

[0034] As one of the implementation methods, refer to Figure 1 The smart gimbal is provided with a charging interface, which includes a first charging interface 11 and a second charging interface 12, wherein the first charging interface 11 is used to charge the smart gimbal, and the second charging interface 12 is used to charge a mobile device clamped on the smart gimbal, and the charging cable of the mobile device is hidden in the cable groove 201 via the wiring space. Preferably, both the first charging interface 11 and the second charging interface 12 are TYPE-C interfaces. Among them, the second charging interface 12 can solve the problem that the mobile device cannot be used on the smart gimbal for a long time.
