Description

Technical Field

[0001] The invention relates to a support base and an electronic device, and in particular to a rotatable support base and an electronic device having the same. Background Art

[0002] Stabilizers such as magnetic levitation gimbals have been widely used in shooting with handheld cameras or mobile cameras. The camera can also be fixed on a vehicle such as a car or a motorcycle through the stabilizer. For example, a brushless motor is provided inside the stabilizer, and the camera device installed on the stabilizer can be driven to rotate by the brushless motor. The brushless motor has strict requirements on the assembly accuracy to ensure that the magnetic sensor can accurately sense the magnetic pole orientation and angle of the motor magnet. If the distance between the sensor and the magnet does not reach the optimal sensing distance, the sensor will not be able to accurately sense the motor magnet, which may easily cause the motor speed to be uneven and burst, causing the camera device on the stabilizer to be unable to move smoothly. In addition, since different sensors usually have different optimal sensing distances, if the distance between the sensor and the magnet cannot be adjusted, the selection of the sensor will be limited.

The same reference numerals will be used to represent the same or similar elements in all drawings.

[0048] Figure 1A It is a three-dimensional schematic diagram of an electronic device according to an embodiment of the present invention. Figure 1B yes Figure 1A Please refer to Figure 1A and Figure 1B The electronic device 10 of this embodiment includes a support base 100 and an electronic unit 200, and the electronic unit 200 is connected to the support base 100. The support base 100 is, for example, a stabilizer or a gimbal, which is used to fix the electronic unit 200 so that the electronic unit 200 maintains a stable position during use. The electronic unit 200 is, for example, a camera device that can capture external images, but the type of the electronic unit 200 is not limited thereto.

[0049] The support base 100 includes a base body 110, and the base body 110 includes a main base body 111, a cover body 112, and an arm body 113. The arm body 113 is connected between the main base body 111 and the electronic unit 200, and the cover body 112 is assembled to the arm body 113. During the operation of the electronic device 10, the support base 100 can drive the electronic unit 200 to rotate smoothly relative to the arm body 113, thereby adjusting the angle and position of the electronic unit 200.

[0050] Figure 2 yes Figure 1A Another three-dimensional schematic diagram of the electronic device. Figure 3 yes Figure 2 Another three-dimensional schematic diagram of the electronic device. Figure 4 yes Figure 2 1 is a cross-sectional view of an electronic device along the AA section line. In order to clearly present the interior of the electronic device, the cover 112 in FIG. Figure 2 1 and the cover 112 and Figure 2 The magnetic sensing component 140 is not in Figure 4 Please refer to Figures 2 to 4 Specifically, the support base 100 further includes an actuating element 120, a magnetic portion 130, a magnetic sensing component 140, and a linkage 170 ( Figure 3), at least one elastic arm 150 and at least one fastener 160. The actuator 120 is, for example, a brushless motor, which is disposed in the arm 113 of the base 110 and includes a rotatable rotor 1201. The linkage 170 is connected to the rotor 1201, and the magnetic part 130 is disposed on the linkage 170 to be connected to the rotor 1201. The linkage 170 and the magnetic part 130 can rotate synchronously with the rotor 1201 of the actuator 120, but the present invention is not limited thereto. In other embodiments, the manner in which the magnetic part 130 is disposed on the rotor 1201 can be adjusted according to actual needs. The magnetic sensing component 140 is disposed in the arm 113 of the base 110 and is aligned with the magnetic part 130 to sense the magnetic pole orientation and angle of the magnetic part 130.

[0051] The elastic arm 150 is disposed on the inner wall W of the base 110 and extends along a supporting direction D1 ( Figure 4 ) supports the magnetic sensing component 140. The elastic arm 150 of this embodiment is an arm-shaped structure integrally connected to the inner wall W and extending inward, and has elasticity, but the present invention is not limited thereto. In other embodiments, other materials (such as metal springs) can also be fixed to the inner wall W. The fastener 160 is arranged along a fastening direction D2 ( Figure 4 ) to fasten the magnetic sensing component 140 to the base 110. Accordingly, the magnetic sensing component 140 can be positioned by the support of the elastic arm 150 without being close to the base 110. Thus, after the magnetic sensing component 140 is installed on the base 110, the distance G between the magnetic sensing component 140 and the magnetic part 130 is ( Figure 4 ) can be adjusted to an optimal distance through the cooperation between the elastic arm 150 and the fastener 160, so that the magnetic sensing component 140 can accurately sense the changes in the magnetic pole orientation and angle of the magnetic part 130 generated by the operation of the actuator 120.

[0052] Figure 5 yes Figure 2 The cross-sectional view of the electronic device along the BB section line. Please refer to Figure 4 and Figure 5 , further, the magnetic sensing component 140 of the present embodiment includes a circuit board 141 and a magnetic sensor 142. The magnetic sensor 142 is disposed on the surface S of the circuit board 141 and faces the magnetic portion 130, and can sense the magnetic pole orientation and angle of the magnetic portion 130. In the present embodiment, the magnetic sensor 142 is a Hall sensor. The base 110 also includes a fixing portion 115 corresponding to the fastener 160, and the top of the fixing portion 115 has a stop surface P. The fastener 160 can fasten the circuit board 141 of the magnetic sensing component 140 toward the stop surface P (that is, move in the fastening direction D2), and the elastic arm 150 is suitable for supporting the circuit board 141 of the magnetic sensing component 140 away from the stop surface P (that is, supporting it in the supporting direction D1).

[0053] In a general design without the elastic arm 150, the circuit board 141 needs to be completely fastened to the stop surface P of the fixing portion 115, that is, the surface S of the circuit board 141 abuts against the stop surface P to prevent the circuit board 141 from being loose and unstable, so that the distance G between the magnetic sensing component 140 and the magnetic portion 130 cannot be adjusted. When the assembly quality is poor or the height of the fixing portion 115 has errors in manufacturing, the distance G will not be the optimal distance, and the magnetic sensing component 140 will not be able to accurately sense the magnetic pole orientation and angle of the magnetic portion 130. As a result, the actuator 120 cannot immediately generate a magnetic force in the correct direction, causing the actuator 120 to operate unsmoothly or even burst, and the electronic unit 200 cannot rotate smoothly.

[0054] In contrast, the support base 100 of the present embodiment cooperates with the elastic arm 150, so that when the circuit board 141 is fastened, the surface S of the circuit board 141 does not need to be close to the stop surface P and can be positioned by the support of the elastic arm 150, so that the distance G between the magnetic sensing component 140 and the magnetic part 130 has room for adjustment. If the distance G is too large, the fastener 160 can be adjusted to move along the fastening direction D2, and the fastener 160 is suitable for resisting the elastic force of at least one elastic arm 150 and pushing the magnetic sensing component 140 toward the stop surface P (that is, moving toward the fastening direction D2) to reduce the distance G. If the distance G is too small, the fastener 160 can be adjusted to move along the supporting direction D1, so that the magnetic sensing component 140 is supported away from the stop surface P (that is, supported away in the supporting direction D1) by the elastic force of the elastic arm 150, so as to increase the distance G. Thus, the distance G can be adjusted to the optimal distance, so that the magnetic sensing component 140 can accurately sense the magnetic pole orientation and angle of the magnetic part 130, so as to achieve the effect of stable operation of the actuator 120. In addition, the elastic arm 150 of this embodiment helps to reduce the impact of external impact on the magnetic sensing component 140, so that the magnetic sensing component 140 is not easily displaced. If the external impact is too large and the distance G changes slightly, the distance G can still be returned to the optimal distance by adjusting the elastic arm 150 and the fastener 160 during maintenance.

[0055] By adjusting the distance G between the magnetic sensing component 140 and the magnetic portion 130 as described above, it is possible to prevent the magnetic sensing component 140 from being too far away from the magnetic portion 130 so that the magnetic sensing component 140 cannot accurately sense the magnetic portion 130. In addition, since the distance G can be adjusted, the support base 100 is suitable for configuring different magnetic sensors (different sensors usually have different optimal sensing distances), which increases the flexibility in sensor selection.

[0056] In addition, the number of the elastic arms 150 in this embodiment is multiple ( Figure 3 The number of fasteners 160 in this embodiment is multiple ( Figure 3The fastener 160 is shown as two, for example, a screw lock, and the fixing portion 115 is, for example, a positioning column with a screw hole, but the types of the fastener 160 and the fixing portion 115 are not limited thereto. The fastener 160 can, for example, pass through the circuit board 141 and be locked to the corresponding fixing portion 115 to fasten the circuit board 141 to the arm 113, but the fastening method is not limited thereto.

[0057] In addition, the actuating element 120, the magnetic portion 130, the magnetic sensing assembly 140, the linkage 170, the elastic arm 150 and the fastener 160 may also be disposed on the main seat body 111 ( Figure 1A ) to rotate the main seat body 111, thereby adjusting the angle and position of the electronic unit 200, but the present invention is not limited to this.

[0058] In summary, the elastic arm of the present invention supports the magnetic sensing component along the supporting direction from the magnetic part to the magnetic sensing component, and the fastener fastens the magnetic sensing component to the seat body along the fastening direction opposite to the supporting direction. Accordingly, the magnetic sensing component can be positioned by the support of the elastic arm when it is not close to the seat body. Thus, through the mutual cooperation of the elastic arm and the fastener, the distance between the magnetic sensing component and the magnetic part has room for adjustment, so that the magnetic sensing component can accurately sense the changes in the magnetic pole orientation and angle generated by the magnetic part when the rotor rotates.
