[0091] As shown in FIG. 6, the upper connecting member 150 includes an upper body 151 and an upper boss 153 disposed on one side of the upper body 151. The upper body 151 is circular, and its size is greater than that of the key hole 145 of the housing 140, thereby blocking the upper body 151 from an outer side of the key hole 145. There are a plurality of upper bosses 153, including two arc-shaped bosses 153a and an “I” shaped boss 153b. The two arc-shaped bosses 153a are opposite to and spaced apart from each other, and the “I” shaped boss 153b is located between the two arc-shaped bosses 153a, which forms a fan-shaped recess 154 with the two arc-shaped bosses 153a respectively.

[0092] As shown in FIG. 5, a surface of the upper body 151 of the upper connecting member 150 that is opposite to the upper boss 153 includes a key slot 151a, and the press key 110 is mounted in the key slot 151a of the upper connecting member 150.

[0093] As shown in FIGS. 4 and 5, the lower connecting member 160 includes a lower body 161 and a lower boss 163 disposed on one side of the lower body 161. The lower body 161 is circular, and its size is greater than that of the key hole 145 of the housing 140, thereby blocking it from an inner side of the key hole 145. There are a plurality of lower bosses 163, including two fan-shaped bosses 163a. The two fan-shaped bosses 163a are opposite to and spaced apart from each other, forming an “I” shaped recess 164 therebetween.

[0094] The lower bosses 163 of the lower connecting member 160 and the upper bosses 153 of the upper connecting member 150 pass through the key hole 145 of the housing 140. For example, the “I” shaped boss 153b of the upper connecting member 150 is received in the “I” shaped recess 164 of the lower connecting member 160, and the two fan-shaped bosses 163a of the lower connecting member 160 are respectively received in the two fan-shaped recesses 154 of the upper connecting member 150.

[0095] The pressure sensor 120 is disposed below the press key 110, and is configured to sense an operation state of the press key 110. The operation state may be a pressing direction of the press key 110, pressing duration of the press key 110, a magnitude applied to the press key 110, etc.

[0096] As illustrated in FIGS. 4 and 5, the pressure sensor 120 is received in the housing 140. The gimbal remote controller 103 further includes a pressure-sensitive rubber pad 170. The lower connecting member 160 is mounted on the pressure-sensitive rubber pad 170, and the pressure-sensitive rubber pad 170 abuts against the pressure sensor 120.

[0097] The specific structure of the pressure-sensitive rubber pad 170 may be designed based on various demands. For example, as shown in FIG. 5, the pressure-sensitive rubber pad 170 includes a base member 171 and a plurality of supporting pillars 173.

[0098] Further, the base member 171 includes a mounting slot 171b for mounting the lower connecting member 160, which facilitates positioning of the lower connecting member 160, and further positioning of the press key 110.

[0099] Further, the base member 171 and the arms 171a of the pressure-sensitive rubber pad 170 may be flat structures. The arms 171a are disposed perpendicular to axial directions of the supporting pillars 173.

[0100] Further, the thicknesses of the base member 171 and the arms 171a of the pressure-sensitive rubber pad 170 are less than the height of the supporting pillars 173. The arms 171a are fixedly connected to middle portions of the supporting pillars 173.

[0101] As shown in FIG. 4, the controller 130 is electrically connected to the pressure sensor 120, and sends a corresponding gimbal control signal for controlling the gimbal 10 in accordance with received user instruction. For example, when the press key 110 is pressed, the pressure sensor 120 transmits the acquired operation state of the press key 110 to the controller 130, and the controller 130 sends a corresponding gimbal control signal in accordance with the operation state of the press key 110.

[0102] In some embodiments, the gimbal control signal is used for controlling at least one of the followings: a rotation state of a rotary shaft of the gimbal 10, an operation mode of the gimbal 10, a function selection of the gimbal 10, and user-defined parameter setting.

[0103] The rotary shaft may be at least one of a roll axis rotatory shaft 101c, a tilt axis rotatory shaft 101d, and a pan axis rotatory shaft 101e. The rotation state may be a direction of rotation, an angle of rotation, a speed of rotation, etc.

[0104] The operation mode of the gimbal 10 includes at least one of the followings: track mode (Smooth Track) off, track mode, and an automatic centering mode.

[0105] The function selection of the gimbal 10 includes at least one of the followings: selecting a speed of rotation of the gimbal 10 in the track mode, and activating a switch that closes a motor.

[0111] As shown in FIGS. 4 and 5, the gimbal remote controller 103 further includes a power key 184. The power key 184 is mounted on the housing 140. For example, as illustrated in FIG. 4, the housing 140 has a power key hole 147, and the power key 184 is mounted in the power key hole 147.

[0112] As shown in FIGS. 4 and 5, the power key 184 includes a cover body 184a, a pressing boss 184b, and an abutment boss 184c. The pressing boss 184b and the abutment boss 184c are disposed on two opposite sides of the cover body 184a respectively, and the pressing boss 184b is disposed corresponding to the abutment boss 184c. The shape and size of the abutment boss 184c match the shape and size of the power key hole 147, allowing the abutment boss 184c to be slidable in the power key hole 147.

[0113] As shown in FIGS. 4 and 5, the gimbal remote controller 103 further includes a press key cover 185. The housing 140 includes an accommodating recess 148 configured to receive the press key cover 185. The power key 184 partially passes through the press key cover 185, and the power key hole 147 is disposed at the bottom of the accommodating recess 148.

[0114] As shown in FIG. 5, the gimbal remote controller 103 further includes a USB interface 186 in communication with the controller. The housing 140 includes a port 149, and the USB interface 186 is mounted in the housing 140 and disposed corresponding to the port 149. For example, the firmware of the gimbal remote controller 103 can be upgraded through the USB interface 186, or charging may be performed through the USB interface 186.

[0115] As shown in FIG. 5, the gimbal remote controller 103 further includes a USB protection cover 187 for covering the USB interface 186. The USB protection cover 187 is flexibly connected to the housing 140.

[0116] For example, as illustrated in FIG. 5, the housing 140 includes a receiving recess 149a. The port 149 is disposed at the bottom of the receiving recess 149a. The bottom of the receiving recess 149a includes a fixing hole 149b. As shown in FIG. 6, the USB protection cover 187 includes a plate body 187a and a connecting pillar 187b extending out from one side of the plate body 187a and embedded into the fixing hole 149b.

[0117] Further, the edge of the plate body 187a includes a snap-fitting part 187c, and a side wall of the receiving recess 149a includes a mating part 187d for engaging with the snap-fitting part 187c. For example, the snap-fitting part 187c is a hook disposed on the edge of the plate body 187a, and the mating part 187d is a slot disposed on a side wall of the receiving recess 149a.

[0118] As shown in FIG. 2, the gimbal remote controller 103 further includes a connecting mechanism 190 that fixes the housing 140 onto the gimbal body 101. For example, as illustrated in FIGS. 1-3, the housing 140 is fixed onto the beam 101b of the gimbal body 101 through the connecting mechanism 190, and the connecting mechanism 190 is disposed near the handle 101a of the gimbal body 101.

[0119] The specific structure of the connecting mechanism 190 may be designed based on various demands. For example, as illustrated in FIG. 4, the connecting mechanism 190 includes an adaptor 191, a clamping member 193, and a locking member 195.

[0120] The adaptor 191 is detachably connected to the housing 140. For example, as illustrated in FIG. 4, the adaptor 191 includes an elastic clamp 191a, and the housing 140 is snapped fit with the elastic clamp 191a to be fixed onto the adaptor 191. For example, the elastic clamp 191a may be a U-shaped clamp, and the housing 140 may press into the elastic clamp 191a, causing its opening to deform, so as to be clamped in the elastic clamp 191a.

[0121] Further, as shown in FIG. 4, inner sides of two arms of the elastic clamp 191a includes fitting bars 191b, and two opposite sides of the housing 140 have slots 142 that can engage with the fitting bars 191b.

[0122] The clamping member 193 is removably connected to the adaptor 191, and the clamping member 193 and the adaptor 191 together form a clamping part 194 (as shown in FIG. 2). For example, as illustrated in FIG. 4, the adaptor 191 has a first arc-shaped concave portion 191c, and the clamping member 193 has a second arc-shaped concave portion 193a. The second arc-shaped concave portion 193a and the first arc-shaped concave portion 191c are disposed in a corresponding manner and are connected together to form the clamping part 194. The connecting mechanism 190 is installed on the beam 101b of the gimbal body 101 through the clamping part 194.

[0123] The locking member 195 is configured to lock the adaptor 191 and the clamping member 193 together. For example, as illustrated in FIG. 4, a lower end of the clamping member 193 is rotatably connected to the adaptor 191, and an upper end is detachably connected to the adaptor 191 through the locking member 195.

[0124] As shown in FIG. 4, an upper end portion of the clamping member 193 includes a locking channel 193b. The locking member 195 includes a screw 196 and a nut 197. One end of the screw 196 may rotatably connect to the adaptor 191, and the other end is received in the locking channel 193b. The nut 197 captures the screw 196 and abuts against an outer side of the locking channel 193b to prevent the screw 196 from falling out of the locking channel 193b.

[0125] Further, an outer side of the nut 197 includes an operation handle 197a. The operation handle 197a may be used to drive the nut 197 to rotate, so as to make it more convenient to operate the nut 197.

[0126] As shown in FIG. 4, the gimbal remote controller 103 further includes an antenna 188 for wirelessly transmitting the gimbal control signal. The antenna 188 is electrically connected to the controller 130. The gimbal remote controller 103 can wirelessly transmit the gimbal control signal through the antenna 188.

[0127] For example, as illustrated in FIG. 4, the antenna 188 is a PCB antenna circuit board, and the gimbal remote controller 103 may include two of the PCB antenna circuit boards. The two PCB antenna circuit boards are respectively disposed on two opposite flanking sides of the control circuit board.

[0128] As shown in FIG. 4, the gimbal remote controller 103 further includes a rechargeable battery 189 that supplies power for the electronic elements described above. The rechargeable battery 189 is received in the housing 140, and is located below the controller 130.

[0129] Further, as shown in FIGS. 4 and 5, the gimbal remote controller 103 further includes a power indicator light 201 and a light guiding pillar 202. The power indicator light 201 is mounted on the controller 130, and the light guiding pillar 202 is mounted on the housing 140 and is disposed corresponding to the power indicator light 201.

[0130] For example, the power indicator light 201 is an LED. The light guiding pillar 202 includes a transverse light guiding rod, an upper light guiding pillar, and a lower light guiding pillar. The upper light guiding pillar and the lower light guiding pillar are respectively vertically connected to two ends of the transverse light guiding rod and extend towards two opposite sides of the transverse light guiding rod. The lower light guiding pillar directs to the power indicator light 201, and the upper light guiding pillar is exposed outside of the housing 140. Light emitted by the power indicator light 201, after passing through a lower light guiding pillar, passes through the transverse light guiding rod to be transferred to the upper light guiding pillar, and finally is guided to the protection cover 183 on the housing 140 by the upper light guiding pillar.

[0131] As described herein, the pressure sensor 120 may be replaced with a rocker potentiometer or other suitable sensors. In such instances, controlling the press key 110 may be achieved by shifting the press key 110.

[0132] The described gimbal remote controller 103 uses a pressure sensor to sense an operation state of a press key, making it more convenient to operate the press key. The size of the gimbal remote controller can be effectively reduced, so that the structure of the gimbal remote controller 103 is compact and makes it more convenient to fix the gimbal remote controller 103 onto a gimbal, thereby facilitating the control over the gimbal remote controller, which advantageously solves the problem that the gimbal cannot be controlled as needed during shooting by a single person.
