BACKGROUND

With the development of science and technology, aerial photography has emerged and become increasingly popular, and aerial photography with unmanned aerial vehicles is increasingly favoured by photographers because of lower costs and safety thereof in comparison with manned aerial photography. Aerial photography with unmanned aerial vehicles is usually carried out by using an aerial vehicle which carries a shooting device, such as a video camera or a photo camera, for shooting. Generally, a photographer uses a remote controller to control the flight of the aerial vehicle, and in order to watch the shooting effect in time, a displaying device such as a display and a mobile phone needs to be mounted on the remote controller, wherein the displaying device is fixed on the remote controller via a holding device. The holding device usually comprises a first and a second clamping member for clamping the displaying device and the first and second clamping members are elastically connected and movable relative to each other, such that the holding device is applicable to displaying devices such as mobile phones of different sizes.

However, the holding device is not applicable to all displaying devices in a larger size range, such as a mobile phone and a tablet, etc., and therefore the application range thereof is largely limited. Moreover, the holding device elastically clamps the displaying device via the first and second clamping members, and therefore the clamping force is small and the clamping is unreliable; and when the holding device shakes, the displaying device can easily fall off of the holding device.

The second protecting member345is provided on the side of the second clamping part343facing towards the first clamping part3233, and the material and function thereof are approximately the same as the first protecting member325. In order to avoid redundancy, details will not be repeated herein in the description.

The first elastic member36is provided between the moving part341and the top housing3231, one end thereof is connected to the bent part3213and the other end is connected to the second clamping member34. In this embodiment, the first elastic member36is a compression spring. In an original state, i.e. when the moving part341is almost completely accommodated in the accommodating cavity3237, the first elastic member36is in a compressed state. When the second clamping part343of the second clamping member34moves towards the direction away from the first clamping part3233, the first elastic member36is gradually stretched to store elastic energy, so as to provide a restoring force of movement to the second clamping member34.

Furthermore, the first clamping member32further comprises a third clamping part327, and the third clamping part327is rotatably connected to the first housing321or/and the second housing323. When the third clamping part327rotates to the position perpendicular to the first housing321and/or the second housing323, a clamping space for clamping external devices such as a tablet computer or a mobile phone is formed between the third clamping part327and the second clamping part343.

In particular, in the embodiments as shown in the figures, the third clamping part327is rotatably connected to the second housing323via a pivot shaft, and an accommodating groove for accommodating the third clamping part327is provided on the second housing323. When the third clamping part327rotates to the position perpendicular to the first housing321and/or the second housing323, the third clamping part327abuts against the side wall of the accommodating groove facing the second clamping part343.

The specific structures of the third clamping part327can be designed according to different requirements, for example, in the embodiments shown in the figures, the third clamping part327is a clamping hook and can be snapped with an external devices such as a tablet computer or a mobile phone to prevent the external device from falling off.

Please refer toFIG. 10, the limiting assembly38is provided on the bottom housing3211corresponding to the mounting hole3239and is used to be snapped with the limiting part3411, so as to limit the mounting position of the second clamping member34relative to the first clamping member32. The limiting assembly38comprises a pivot shaft381, a limiter383rotatably sheathed on the pivot shaft381, and pressing member385and the second elastic member387both provided on the limiter383.

The pivot shaft381is fixedly provided on the top housing3231and close to the limiting part3411on the moving part341. The limiter383is an approximately bent block shape and the approximately middle position thereof is rotatably sheathed on the pivot shaft381. Under the action of an external force, the limiter383can rotate around the pivot shaft381. In this embodiment, the limiter383is a rotating stir wheel with one end thereof being snapped with the sawtooth rack of the limiting part3411and the other end thereof being as operating end. Particularly, the limiter383comprises a rotating part3831and a pressing part3833formed on one end of the rotating part3831. The rotating part3831extends from the pivot shaft381towards the limiting part3411; the pressing part3833extends from the pivot shaft381towards the mounting hole3239; and a certain angle is formed between the rotating part3831and the pressing part3833. The end of the rotating part3831which is close to the limiting part3411protrudes to form a stopping part3835. In this embodiment, the stopping part3835is in a protruding tooth shape and is used to snap the saw teeth of the limiting part3411. The pressing member385is mounted in the mounting hole3239with one end being abutted against the pressing part3833of the limiter383and the other end protruding out of the side wall3235. One end of the second elastic member387is connected to the pressing part3833and the other end is connected to the top housing3231. In this embodiment, the second elastic member387is a helical compression spring.

When the pressing member385is pressed by an external force, the limiter383is driven thereby to rotate around the pivot shaft381, such that the second elastic member387elastically deforms and is compressed, and at the same time, the pressing part3833brings the stopping part3835to move away from the limiting part3411, therefore the stopping part3835is no longer snap-fitted with the limiting part3411, and the second clamping member34can move relative to the first clamping member32. When the external force is lifted and under the action of the elastic restoring force of the second elastic member387, the limiter383rotates reversely around the pivot shaft381and the stopping part3835is again snapped in the limiting part3411, such that the second clamping member34is fixed relative to the first clamping member32.

When assembling the bracket100in this embodiment, firstly, the limiting assembly38is arranged on the second housing323and the moving part341is arranged in a parallel manner on the top housing3231, such that the stopping part3835is snapped in the limiting part3411. The meshing member3219is rotatably arranged on the bottom housing3211; the first elastic member36is connected between the bent part3213and the second clamping member34; and then the first housing321is snap-fitted on the second housing323, such that the meshing member3219is meshed with the meshing part3413. Next, the first protecting member325and the second protecting member345are arranged on the first clamping part3233, the top housing3231and the second clamping part343. Then, the holding mechanism30is mounted on the connecting frame12via the fastening assembly16, and then the locating assembly14is arranged on the connecting frame12. When the bracket100needs to be mounted on the remote controller body201, firstly, the fastening shaft141is inserted in the locating hole of the remote controller body201and then the fastening sleeve143is screwed in the locating hole, thereby firmly mounting the bracket100on the remote controller body201.

Please again refer toFIG. 1, wherein in a non-use state, the holding mechanism30is approximately parallel to the remote controller body201, the top housing3231thereof faces the remote controller body201, and the first clamping part3233is partially accommodated in the accommodating space127of the connecting frame12. At this time, the fastening assembly16steadily fixes the holding mechanism30on the connecting frame12and the operating member165of the fastening assembly16is relatively close to the locking member161.

When using the bracket100and the remote controller200of the present disclosure, firstly, the operating member165rotates to cause the snap-fitting part1657to correspond to the sliding groove1638and then the operating member165is pulled to move away from the locking member161. When the snap-fitting part1657slides into the snapping part1637along the sliding groove1638, the operating member165is slightly rotated along a first direction to enable the snap-fitting part1657to be dislocated from the sliding groove1638and to abut against the side wall of the snapping part1637. The operating member165continues rotating along the first direction, the operating member165pushes against the side wall of the snapping part1637via the snap-fitting part1657, such that the fastening member163as a whole rotates and moves relatively away from the locking member161, thereby enabling the two locking parts3215to be restored elastically and the connecting part125clamped between the two locking parts3215to be released. At this time, the holding mechanism30is rotatable relative to the seat10.

Secondly, the holding mechanism30rotates around the fastening assembly16until the holding mechanism30rotates to a required operating angle, the operating member165rotates along a second direction opposite to the first direction, such that the operating member165brings the fastening member163to rotate until it is screwed with the locking member161, and the fastening member163and the locking member161together clamp the two locking parts3215, thereby fixing the holding mechanism30relative to the seat10. Again, the operating member165slightly rotates along the first direction, and the operating member165is released after the snap-fitting member1657corresponds to the sliding groove1638. Under the action of the elastic restoring force of the resetting member167, the snap-fitting part1657slides along and moves away from the flange part1639along the sliding groove1638, and the operating member165as a whole is relatively close to the locking member161.

Then, an external force is applied to the pressing member385, such that the snap-fitting between the stopping part3835and the limiting part3411is lifted, and at the same time, the second clamping part343is pulled to enable it to move away from the first clamping part3233. At this time, the first elastic member36is stretched and stores elastic energy. When the spacing between the first clamping part3233and the second clamping part343meets requirements, the second clamping part343and the pressing member385are released, such that the first clamping part3233is fixed relative to the second clamping part343.

At last, a displaying device such as a mobile phone, a display or a tablet computer is mounted between the first clamping part3233and the second clamping part343. The pressing member385is pressed again, and under the action of the elastic restoring force of the first elastic member36, the second clamping member343is relatively close to the first clamping part3233and abuts against the displaying device. The first elastic member36still has the tendency to recover from a deformed state to a normal state and the elastic force thereof is converted into the clamping force for the displaying device, thereby holding the displaying device on the holding mechanism30. The pressing member385is released again to enable the stopping part3835to once again be snapped with the limiting part3411, and the clamping part3233and the second clamping part343are thus further fixed so that the displaying device is firmly clamped on the holding mechanism30.

When the installation angle of the holding mechanism30relative to the remote controller body201needs to be adjusted, the fastening assembly16is released according to the method, such that the holding mechanism30is rotatable relative to the seat10. The holding mechanism30rotates to the needed installation angle, and the holding mechanism30is once again fixed relative to the seat10via the holding mechanism16. Such holding mechanism30of the remote controller200of the present disclosure uses both the first clamping part3233and second clamping part343to clamp the displaying device, the second clamping part343can move relative to the first clamping part3233, such that the bracket100can be applied to displaying devices of different sizes and the application range of the holding mechanism is broad. In addition, the holding mechanism30limits the distance between the first clamping part3233and the second clamping part343by snapping with the limiter383and the limiting part3411, such that the holding mechanism30is applicable to displaying devices with larger size differences, which further enlarges the application range of the holding mechanism. The limiter38and the limiting part3411can be firmly snap-fitted, such that the clamping from the holding mechanism on the displaying device is more reliable. Moreover, the installation position of the holding mechanism30, as a whole, relative to the remote controller body201can be adjusted via the fastening assembly16, such that the use of the remote controller200is more flexible.

It is understood that the resetting member167can be omitted and when using the bracket100, the operating member165can be reset manually.

It is understood that the number of the first elastic member36can be one or more.

It is understood that the first elastic member36can be omitted, and when using the holding mechanism30, the mounting position of the first clamping member32relative to the second clamping member34can be limited by snapping the limiting assembly38of the first clamping member32onto the second clamping member34, or separating the two from each other, thereby adjusting the distance between the first clamping part3233and the second clamping part343, and the holding mechanism30can be applied to displaying device of different sizes.

It is understood that the second elastic member387can be an elastic member of another structure, for example, a torsional spring, a coil spring, an elastic plate, an elastic sleeve, etc., and one end of the second elastic member387abuts against the first clamping member32and the other end abuts against the pressing member385to provide a restoring force of movement to the limiter383.

It is understood that the second elastic member387can be omitted and the limiter383may be designed with an elastic structure, and when an external force is applied, the limiter can be snapped with or separated from the limiting part3411. Alternatively, the limiter383as a whole is arranged on the second housing323and can be a pluggable structure, and the stopping part3835on the limiter383is snapped with or separated from the limiting part3411by inserting the limiter383into the second housing323, or pulling the limiter out from the second housing323.

It is understood that the fastening assembly16can be omitted, and when assembling the bracket100, the holding mechanism30may be fastened on the seat10via a screw.

It is understood that the number of snap-fitting parts1657can be one or more, and accordingly, the numbers of the snapping part1637and the sliding groove1638can also be one or more. When the numbers of the snap-fitting part1657, the snapping part1637and the sliding groove1638are more than one, the plurality of snap-fitting parts1657are formed on the inner wall of the first sheathing hole1651separate from each other with a spacing in between, and the plurality of snapping parts1637are formed on the mating part1635separate from each other and is in a one-to-one correspondence relationship with the plurality of snap-fitting parts1657.
