As shown in
In some embodiments, the handheld gimbal 100 can be configured for stabilization. In the examples shown in
In some embodiments, the controller can be configured to obtain the folding detection information collected by the first detection member and the payload detection information collected by the second detection member. According to the folding detection information, whether the gimbal member 12 is in a folded state can be determined, and according to the payload detection information, whether the gimbal member 12 carries a payload can be determined. When the gimbal member 12 is determined to be without the payload and in a folded state, the gimbal member 12 can be controlled to be in a standby mode. When the gimbal member 12 is determined to carry a payload and be in an unfolded state, the gimbal member 12 can be controlled to be in an operation mode.
The controller can control the gimbal member 12 to be in the standby mode when the gimbal member 12 does not carry the payload and is in the folded state. Then, the user can conveniently use the payload independently. When the gimbal member 12 carries the payload and is in an unfolded state, the controller can control the gimbal member 12 to be in the operation mode to restore the normal operation of the handheld gimbal 100. Thus, the application convenience of the handheld gimbal 100 can be improved, which facilitates the user operation and improves the user experience.
The gimbal member 12 includes a first connection arm 121 (e.g., an integral structure integrated with the housing of a yaw motor 122), the yaw motor 122, a second connection arm 123, a pitch motor 124, a third connection arm 125, the roll motor 126, and a rotation connector 127. The rotation connector 127 is arranged between the first connection arm 121 and the second connection arm 123. One end of the rotation connector 127 is rotatably connected to the first connection arm 121, and the other end of the rotation connector 127 is rotatably connected to the second connection arm 123. The gimbal member 12 can rotate around the rotation connector 127 to switch between the folded state and the unfolded state (the handheld gimbal 100 in
The yaw motor 122 can be connected to the top member 112 of the handheld member 11. One end of the first connection arm 121 can be rotatably connected to an end of the second connection arm 123 through the rotation connector 127. The other end of the first connection arm 121 can be fixedly connected to the rotor member of the yaw motor 122. The other end of the second connection arm 123 can be rotatably connected to the first connection arm 121 through the rotation connector 127. An end of the third connection arm 125 can be fixedly connected to the stator member of the roll motor 126. The other end of the third connection arm 125 can be fixedly connected to the rotor member of the pitch motor 124. In some other embodiments, the gimbal member can also be a single-shaft or duo-shaft gimbal member. In some other embodiments, the yaw motor 122, the pitch motor 124, and the roll motor 126 can be connected in sequences other than the sequence above.
In some embodiments, the first detection member can include a first magnetic member and a first magnetic sensor. The first magnetic member can be arranged at the first connection arm 121, and the first magnetic sensor can be arranged at the second connection arm 123. In some other embodiments, the first magnetic member can be arranged at the second connection arm 123, and the first magnetic sensor can be arranged at the first connection arm 121. The first magnetic sensor can be configured to collect the first magnetic field strength. The first magnetic member can be a single magnetic member or a dual magnetic member.
When the gimbal member 12 is in the unfolded state, the first connection arm 121 does not contact the second connection arm 123, and the first magnetic sensor cannot sense the magnetic field of the first magnetic member. As shown in
In some embodiments, the first detection member can include an angle sensor. The angle sensor can be arranged at the rotation connector 127 and configured to collect the angle between the first connection arm 121 and the second connection arm 123. The first connection arm 121 can have an angle with the second connection arm 123. As shown in
In some embodiments, the folding detection information can include at least one of the first magnetic field strength collected by the first magnetic sensor and the angle between the first connection arm 121 and the second connection arm 123. The controller can be further configured to determine that the gimbal member 12 is in the folded state when the first magnetic field strength is greater than or equal to a predetermined first magnetic field strength threshold and/or the angle between the first connection arm 121 and the second connection arm 123 is less than or equal to a predetermined angle threshold, and determine that the gimbal member 12 is in the unfolded state when the first magnetic field strength is less than the predetermined first magnetic field strength threshold and/or the angle between the first connection arm 121 and the second connection arm 123 is greater than the predetermined angle threshold. The first magnetic field strength threshold and the predetermined angle threshold can be set as needed, which is not limited here.
As shown in
When the payload connector 200 carries a payload, the pressure value collected by the pressure sensor can be greater than the pressure value collected by the pressure sensor when the payload connector 200 does not carry the payload. Moreover, the pressure value collected by the pressure sensor when the payload connector 200 carries the payload can be related to the weight of the payload. Therefore, with the pressure value collected by the pressure sensor, whether the payload connector 200 carries the payload can be quickly and conveniently determined. In some embodiments, a second magnetic member can be arranged at the back side of the payload. The second magnetic member can be a single magnetic member or dual magnetic member. When the payload connector 200 carries the payload, the second magnetic sensor can sense the magnetic field of the second magnetic member. When the payload connector 200 does not carry the payload, the second magnetic sensor cannot sense the magnetic field of the second magnetic member. Thus, with the second magnetic field strength collected by the second magnetic sensor, whether the payload connector 200 carries the payload can be quickly and conveniently determined.
In some embodiments, the payload detection information can include at least one of the second magnetic field strength collected by the second magnetic sensor and the pressure value collected by the pressure sensor. The controller can be further configured to determine that the gimbal member 12 carries the payload when the second magnetic field strength is greater than or equal to a predetermined second magnetic field strength threshold and/or the pressure value is greater than or equal to the predetermined pressure threshold, and determine that the gimbal member 12 does not carry the payload when the second magnetic field strength is less than the second magnetic field strength threshold and/or when the pressure value is less than the predetermined pressure threshold. The second magnetic field strength threshold and the predetermined pressure threshold can be arranged as needed and are not limited here.
As shown in
In some embodiments, the roll motor 126 can include a stator member and a rotor member that is rotatable relative to the stator member. The first attraction member 128 can be fixedly connected to the stator member or the rotor member of the roll motor 126. The first attraction member 128 can be magnetically attracted to the second attraction member 21. Thus, when the payload connector 200 is installed, the rotor member can rotate relative to the stator member until the first attraction member 128 and the second attraction member 21 face each other and are attached together. Then, the payload connector 200 can be detachably mounted at the rotor member or the stator member, and the roll motor 126 can drive the payload connector 200 to rotate. The magnetic attraction connection method utilizes the mutual attraction between magnets and magnetic materials that can be attracted by magnets, or the attraction between two magnets with opposite polarities. The magnetic member has two poles, an N pole, and an S pole, and the magnetic material is a soft magnetic material.
The first attraction member 128 can include a single-sided single-pole magnetic member, a single-sided dual-pole magnetic member, or another magnetizable member. The other magnetizable member can be attracted by the magnetic member. For example, the other magnetizable member can include iron, nickel, and cobalt. In some embodiments, the single-sided single-pole magnetic member can include two end surfaces facing away from each other. Each end surface can include a unique magnetic pole. One end surface can have N pole, and the other end surface can have S pole. The magnetic induction curve of the single-sided single-pole magnetic member passes from the N pole to the S pole. The magnetic path of the single-sided single-pole magnetic member can be relatively open and have a wide range of attracting other attraction members. The shape of the single-sided single-pole magnetic member can include, but is not limited to, a circular shape, an elliptical shape, and a rectangular shape.
In the handheld gimbal 100 shown in
In some embodiments, the second attraction member 21 can include a single-sided single-pole magnetic member and a single-sided dual-pole magnetic member. The number of single-sided single-pole magnetic member and the number of single-sided dual-pole magnetic member in the second attraction member 21 can be the same as the number of single-sided single-pole magnetic member and the number of single-sided dual-pole magnetic member in the first attraction member 128, respectively. The polarities of the corresponding magnetic member of the second attraction member 21 can be opposite to the polarities of the magnetic member of the first attraction member 128. When the payload connector 200 approaches the gimbal member from a distance of 30 mm or more, the payload connector 200 can first be attracted by the single-sided single-pole magnetic member to guide the roll motor 126 and the payload connector 200 to automatically correct the positions to cause the relative angle between the roll motor 126 and the payload connector 200 to be in a certain ranged. When the roll motor 126 and the payload connector 200 continue to approach each other, and the distance is around 5 mm, the attraction force of the single-sided dual-pole magnetic member can gradually increase to further correct the positions of the roll motor 126 and the payload connector 200. When the roll motor 126 is close to the payload connector 200, the roll motor 126 and the payload connector 200 can be accurately positioned, which prevents the payload connector 200 from tilting to a side.
In some embodiments, in the standby mode, the motors of the gimbal member 12 can be in a powered-off state and/or a locked state. For example, the roll motor 126, the pitch motor 124, and the yaw motor 122 can be in the powered-off state and/or the locked state. In the operation mode, the motors of the gimbal member 12 can be in a powered-on state and an unlocked state. For example, the roll motor 126, the pitch motor 124, and the yaw motor 122 can be in the powered-on state and the unlocked state. A motor in the locked state cannot rotate freely, and a motor in the unlocked state can rotate freely within the position limits of the motor.
As shown in
At S101, the folding detection information collected by the first detection member and the payload detection information collected by the second detection member of the gimbal member are obtained.
For example, the first detection member can include the first magnetic sensor and/or the angle sensor. The folding detection information can include the first magnetic field strength collected by the first magnetic sensor and/or the angle between the first connection arm and the second connection arm of the gimbal member collected by the angle sensor. For example, the second detection member can include the second magnetic sensor and/or pressure sensor. The payload detection information can include the second magnetic field strength collected by the second magnetic sensor and/or the pressure value collected by the pressure sensor.
At S102, whether the gimbal member is in the folded state is determined based on the folding detection information, and whether the gimbal member carries the payload is determined according to the payload detection information.
For example, when the first magnetic field strength is greater than or equal to the predetermined first magnetic field strength threshold and/or the angle is less than or equal to the predetermined angle threshold, the gimbal member can be determined to be in the folded state. When the first magnetic field strength is less than the first magnetic field strength threshold and/or the angle is greater than the predetermined angle threshold, the gimbal member can be determined to be in the unfolded state. The first magnetic field strength threshold and the predetermined angle threshold can be set as needed and are not limited here.
For example, when the second magnetic field strength is greater than or equal to the predetermined second magnetic field strength threshold and/or the pressure value is greater than or equal to the predetermined pressure threshold, the gimbal member can be determined to carry the payload. When the second magnetic field strength is less than the second magnetic field strength threshold and/or the pressure value is less than the predetermined pressure threshold, the gimbal member can be determined to not carry the payload. The second magnetic field strength threshold and the predetermined pressure threshold can be set as needed and not be limited here.
At S103, when the gimbal member is determined to not carry the payload and be in the folded state, the gimbal member is controlled to be in the standby mode.
In the standby mode, the motors of the gimbal member can be in the powered-off state and/or the locked state. For example, the roll motor, the pitch motor, and the yaw motor of the gimbal member can be in the powered-off state and/or the locked state. The motor in the locked state cannot rotate freely. Controlling the gimbal member to be in the standby mode can include controlling the motors of the gimbal member to be in the powered-off state and/or the locked state.
At S104, when the gimbal member is determined to carry the payload and be in the unfolded state, the gimbal member is controlled to be in the operation mode.
In the operation mode, the motors of the gimbal member can be in the powered-on state and the unlocked state. For example, the roll motor, the pitch motor, and the yaw motor of the gimbal member can be in the powered-on state and the unlocked state. The motor in the unlocked state can rotate freely within the position limits of the motor. Controlling the gimbal member to be in the operation mode can include controlling the motors of the gimbal member to be in the powered-on state and the unlocked state.
In the control method for the handheld gimbal of embodiments of the present disclosure, when the gimbal member does not carry the payload and is in the folded state, controlling the gimbal member to be in the standby mode can facilitate the user to use the payload independently. When the gimbal member carries the payload and is in the unfolded state, the gimbal member can be controlled to be in the operation mode to restore the normal operation of the handheld gimbal, which greatly improves the application convenience of the handheld gimbal, facilitates the user to operate, and improves the user experience.
