Wherein, the movable platform can be an unmanned aerial vehicle, a handheld device and the like. The bracket assembly will now be described in four embodiments.

Fig. 6 shows a schematic view of another angle of the carriage assembly and the movable platform body 100 of fig. 5. Fig. 7 shows a cross-sectional schematic view of the carriage assembly and the movable platform body 100 of fig. 5. Fig. 8 shows an exploded view of the rotational structure 30 of the carriage assembly of fig. 1.

As shown in fig. 1 to 7, the bracket assembly includes a mounting base 10 and a bracket 20. Wherein the mounting base 10 is for mounting on the movable platform body 100. The support 20 is movably coupled to the mounting base 10 such that the support 20 has a stored position close to the movable platform main body 100 and an unfolded position away from the movable platform main body 100. During movement of the moveable platform to which the carriage assembly is mounted, at least a portion of the carriage 20 is elevated above the moveable platform body 100 when the carriage 20 is in the deployed position. At this time, the unfolded support 20 can be used as a lifting part, and the user holds the part of the support 20 higher than the movable platform main body 100 to lift the movable platform, thereby realizing the switching of the movable platform into the carafe mode, facilitating the movable platform to move at a lower position from the ground. When the support 20 is not needed to be reused, the support 20 is moved to the storage position, the storage is simple, the operation is simpler, frequent disassembly and assembly are not needed between the support assembly and the movable platform main body 100, the problem that accessories are easy to lose is avoided, and the use is convenient for users.

It should be noted that the type of movable platform may be various. If the portable platform passes through the bracket component and realizes the kettle-lifting mode, the weight and the volume of portable platform then need satisfy the requirement that the user can mention. Theoretically, as long as the movable platform meeting the requirements can adopt the bracket assembly of the embodiment of the application to realize the kettle lifting mode.

Taking the movable platform as an unmanned aerial vehicle for example, the movable platform body 100 is the fuselage of the unmanned aerial vehicle, and at least a portion of the support 20 is higher than the fuselage of the unmanned aerial vehicle when the support 20 is in the deployed position. Herein, "above" is to be understood as meaning that at least part of the support 20 is above the fuselage of the unmanned aerial vehicle in the ventral to dorsal direction of the fuselage of the unmanned aerial vehicle.

The unmanned aerial vehicle is loaded with a load of the type of a camera, a measuring device (such as a laser radar or a millimeter wave radar), a searchlight, or the like. The user holds the unfolded support 20 to switch the unmanned aerial vehicle into the kettle lifting mode, so that the functions of the unmanned aerial vehicle are expanded. If the load carried by the unmanned aerial vehicle is a shooting device, the kettle lifting mode can realize low-position shooting. If the load carried by the unmanned aerial vehicle is a measuring device, the kettle lifting mode can realize measurement of an area with a lower distance from the ground. If the load carried by the unmanned aerial vehicle is a searchlighting device, the kettle lifting mode can realize illumination of an area with a lower distance from the ground.

Taking the movable platform as an example of a handheld device, similarly, the handheld device carrying loads can be various, and after the handheld device is switched to the kettle lifting mode by the support 20 which is unfolded by being held by a user, functions corresponding to different loads can be realized. The specific structure of the handheld device may also be varied. For example, a handheld device includes a handheld portion and a cradle head connected to the handheld portion, and the cradle head is loaded with a load of a type such as a photographing device, a measuring device, and a searchlight device. It should be noted that the movable platform body 100 is a handheld portion and a load or a handheld portion, a cradle head and a load of the handheld device, and at least a portion of the support 20 is higher than the movable platform body 100, and it is understood that at least a portion of the support 20 that is deployed is located above the movable platform body 100 when the handheld device performs the low-attitude movement.

In addition, the holder 20 may be provided with a member that needs to avoid the shielding, such as the sensor 200, the imaging device, or the like. Since at least a portion of the support 20 is higher than the movable platform body 100, providing the above-described components on this portion enables the above-described components to be shielded from the movable platform body 100 or other structures connected to the movable platform body 100.

Taking the movable platform as an unmanned aerial vehicle as an example, the movable platform main body 100 is a body of the unmanned aerial vehicle, and the sensor 200 is arranged on a part higher than the body of the unmanned aerial vehicle when the bracket 20 is located at the unfolding position, so that the problem that the sensing blind area is large due to the fact that the field angle of the sensor 200 is shielded by the body, a horn connected with the body, a power suit and other structures is avoided, the number and the positions of the sensors 200 are reasonably designed, and the omnidirectional sensing of the unmanned aerial vehicle can be realized by combining a sensing device on the body. Compared with the prior technical scheme of realizing omnidirectional sensing by adopting the fisheye sensor, the cost can be reduced to a certain extent by arranging the sensor 200 through the bracket 20 to realize omnidirectional sensing.

The sensor 200 may be a binocular vision sensor, the bracket 20 is beneficial to expanding the size of the base line of the binocular vision sensor, and the bracket 20 can have a large detection distance and a large sensing capability by designing the distance between two vision sensors in the binocular vision sensor. Of course, the sensor 200 may also be other types of sensors, such as infrared sensors, lidar, ultrasonic sensors, and the like.

As shown in fig. 1-7, in some embodiments of the present application, the support 20 is a rigid support to facilitate holding or mounting the sensor 200. The bracket 20 includes a first bracket 21 and a second bracket 22 connected to each other, the second bracket 22 is movably connected to the mounting base 10, and the second bracket 22 is disposed to be inclined with respect to the first bracket 21. When the stand 20 is located at the deployed position and the movable platform body 100 is moved, the first stand 21 is higher than the movable platform body 100. Through the reasonable design of the inclination angles of the first bracket 21 and the second bracket 22 and the connection position of the second bracket 22 and the mounting base 10, when the bracket 20 is located at the storage position, the first bracket 21 and/or the second bracket 22 can be attached to the movable platform main body 100 as much as possible, so that the volume after storage is smaller. Meanwhile, the first support 21 and the second support 22 are arranged obliquely, so that a user can hold the first support 21 in a hand when in the kettle lifting mode, and the kettle is more convenient to hold. Of course, it is understood that the specific structure of the bracket 20 is not limited thereto, and in other embodiments not shown in the figures, the bracket 20 may have other structures.

As shown in fig. 5-7, in some embodiments of the present application, when the stand 20 is in the deployed position, the centerline of the first stand 21 is coplanar with the centerline of the movable platform body 100, which may further facilitate a user to hold the first stand 21. Preferably, in a state where the movable platform is moving, a plane formed by a center line of the first bracket 21 and a center line of the movable platform main body 100 is parallel to a vertical plane, that is, the first bracket 21 is located right above the center of the movable platform main body 100, which enables a user to save more labor when holding the first bracket 21. Preferably, the center line of the first bracket 21 and the center line of the movable platform body 100 are parallel to each other. Of course, the center line of the first support 21 and the center line of the movable platform body 100 may be disposed at an angle.

As shown in fig. 1 to 7, in some embodiments of the present application, a portion of the bracket 20 higher than the movable platform body 100 has a sensor mounting portion 24 for mounting the sensor 200. The number and position of the sensor mounts 24 may be designed appropriately according to the type of the movable platform and the application scenario. In this case, factors such as the angle of view of the sensor 200 need to be taken into consideration in designing, such as the inclination angles of the first bracket 21 and the second bracket 22, the connecting position of the second bracket 22 to the mounting base 10, and the position where the first bracket 21 is located after the bracket 20 is unfolded. Further, the sensor mounting portion 24 includes a mounting groove 241 disposed on the bracket 20 and a routing concave portion 242 communicated with the mounting groove 241, the mounting groove 241 is used for accommodating the sensor 200, and the routing concave portion 242 is used for accommodating a transmission line connected with the sensor 200, so as to further facilitate the arrangement of the sensor 200 and the transmission line. The transmission line may be a flexible circuit board, a coaxial line, or the like.

The bracket 20 of the embodiment of the present application is movably connected to the mounting base 10 in various ways, for example, by a rotational connection, a sliding connection, and the like. Regardless of the articulation, the stand 20 should be able to remain in the stowed and deployed positions.

As shown in fig. 1-7, in some embodiments of the present application, the bracket 20 is rotatably coupled to the mounting base 10. As shown in fig. 8, the rack assembly further comprises a rotating structure 30, and the rack 20 is rotatably connected to the mounting base 10 through the rotating structure 30 and can hold the rack 20 at least in the storage position and the extended position. The rotating structure 30 includes a rotating shaft 31, a rotatable member 32, a locking member 33, a locking fitting 34, and a first elastic member 35. Wherein, the rotating shaft 31 is fixedly connected with the installation basal body 10. It should be noted that "fixedly connected" is used herein in relation to "movably connected" and "fixedly connected" refers to the two components being fixed relative to each other after they are assembled. The rotatable member 32 and the holder 20 are relatively fixed in the circumferential direction of the rotating shaft 31 so that the rotatable member 32 and the holder 20 can rotate around the rotating shaft 31 in synchronization. The locking piece 33 is fixedly connected to the mounting base 10. The catch fitting 34 and the catch 33 are arranged in the axial direction of the rotating shaft 31. The engaging mating part 34 and the rotatable part 32 are fixed relative to each other in the circumferential direction of the rotating shaft 31 and are movable relative to each other in the axial direction of the rotating shaft 31, that is, the engaging mating part 34 can be driven to rotate synchronously when the rotatable part 32 and the bracket 20 rotate around the rotating shaft 31, but the engaging mating part 34 is not limited in the axial direction of the rotating shaft 31, and the engaging mating part 34 can move relative to the rotatable part 32 in the axial direction of the rotating shaft 31. The first elastic member 35 serves to always apply an elastic force to the catching mating member 34 toward the catching piece 33.

The support frame 20 is described as being rotated from the storage position to the deployed position. When the holder 20 is at the storage position, the locking fitting 34 and the locking piece 33 are in the locked state, thereby holding the holder 20 at the storage position. When the bracket 20 and the rotatable member 32 start to rotate, the rotatable member 32 drives the engaging mating member 34 to rotate, and the engaging mating member 34 overcomes the elastic force exerted by the first elastic member 35 to move away from the engaging member 33 while rotating, so that the engaging mating member 34 and the engaging member 33 are switched from the engaging state to the releasing state. After the holder 20 and the rotatable member 32 are rotated to the position (to the extended position or to an intermediate position between the stored position and the extended position where the holding member needs to stay), the engaging mating member 34 is driven to move toward the engaging member 33 by the elastic force applied by the first elastic member 35, so that the engaging mating member 34 and the engaging member 33 are switched from the disengaged state to the engaged state, and the holder 20 is held at the position (the extended position or the intermediate position). The process of rotating the stand 20 from the deployed position to the stowed position is similar to that described above and will not be described further herein.

As shown in fig. 1, 4, 7 and 8, in some embodiments of the present application, the bracket 20 has a rotation coupling hole 23, and the rotatable member 32 is inserted into the rotation coupling hole 23. The rotary connecting hole 23 is adapted to the shape of the rotatable member 32, and the hole wall of the rotary connecting hole 23 has at least two first stop surfaces 231 connected in sequence along the circumferential direction of the rotating shaft 31, and the circumferential side wall of the rotatable member 32 of the rotary structure 30 has a first stop mating surface 321 corresponding to the first stop surfaces 231. When the rotatable component 32 is inserted into the rotation connecting hole 23, the first stop surface 231 abuts against and limits the position of the corresponding first stop mating surface 321, so that the rotatable component 32 and the bracket 20 are relatively fixed in the circumferential direction of the rotating shaft 31. In the embodiment shown in the drawings, the rotation connecting hole 23 and the rotatable member 32 are formed in a substantially square shape in cross section, four corners of the square shape are chamfered, each surface of the rotation connecting hole 23 in the circumferential direction thereof can be regarded as a first stopper surface 231, and each surface of the outer wall of the rotatable member 32 in the circumferential direction thereof can be regarded as a first stopper mating surface 321. Of course, the shapes of the rotation connecting hole 23 and the rotatable member 32 and the numbers of the first stop surface 231 and the first stop mating surface 321 are not limited thereto, and in other embodiments not shown in the drawings, other shapes capable of achieving circumferential limit may be adopted, for example, a triangle shape, an oval shape, an irregular shape, and the like.

In some embodiments of the present application, as shown in FIG. 8, the rotatable member 32 has a receiving cavity (not shown) in which the capture engagement member 34 is located. The receiving cavity is adapted to the shape of the engaging mating member 34, the cavity wall of the receiving cavity has at least two second stopping surfaces sequentially connected along the circumferential direction of the rotating shaft 31, and the circumferential side wall of the engaging mating member 34 has a second stopping mating surface 342 corresponding to the second stopping surfaces. When the engaging mating member 34 is disposed in the receiving cavity, the second stopping surface abuts against and limits the corresponding second stopping mating surface 342, so that the engaging mating member 34 and the rotatable member 32 are relatively fixed in the circumferential direction of the rotating shaft 31. In the embodiment shown in the figures, the latching counterpart 34 is also approximately square in cross-sectional shape, with the corners of the square being chamfered, and the respective surfaces of the wall of the receiving chamber in its circumferential direction can be regarded as second stop surfaces, and the respective surfaces of the outer wall of the latching counterpart 34 in its circumferential direction can be regarded as second stop mating surfaces 342. Of course, the shapes of the receiving cavity and the locking mating member 34 and the number of the second stopping surfaces and the second stopping mating surfaces 342 are not limited to this, and in other embodiments not shown in the drawings, other shapes capable of achieving circumferential limitation, such as triangle, ellipse, irregular shape, etc., may also be adopted.

It should be noted that the implementation of the circumferential limit between the rotation connecting hole 23 and the rotatable member 32 and/or between the rotatable member 32 and the locking mating member 34 is not limited to the above-mentioned manner. In other embodiments of the present application, the limit between the two components may be achieved by other stop structures, for example, a stop groove and a stop block are provided between the two components (the rotation connecting hole 23 and the rotatable component 32 and/or the rotatable component 32 and the stop mating component 34), the stop block is inserted into the stop groove, the stop groove is matched with the size of the stop block, or the stop groove extends along the axial direction of the rotating shaft 31, and the stop block is limited along the width direction of the stop groove but can slide along the extending direction of the stop groove.

As shown in fig. 8, in some embodiments of the present invention, one of the locking piece 33 and the locking fitting 34 has a locking recess 331, and the other has a locking protrusion 341 engageable with the locking recess 331, and the locking recess 331 and/or the locking protrusion 341 are provided in plurality at intervals in the circumferential direction of the rotating shaft 31. Even if the plurality of locking recesses 331 are provided in the circumferential direction or the plurality of locking protrusions 341 are provided in the circumferential direction, a plurality of locking positions can be formed in the circumferential direction of the rotation shaft 31. Through the reasonable design of a plurality of clamping positions, the bracket 20 can be selectively kept at a position (such as an unfolding position, a middle position or a storage position) corresponding to one clamping position in the rotating process, and the use is more flexible.

Of course, it is understood that the manner of locking the engaging element 34 and the locking member 33 is not limited to this, and in other embodiments, the engaging element 34 and the locking member 33 may be locked and limited by friction force generated by pressing, for example, the engaging element 34 and the locking member 33 are separated by moving the engaging element 34 away from the locking member 33, and then the engaging element 34 is in a released state, and when the engaging element 34 is pressed against the locking member 33 by the first elastic member 35, both are in a locked state.

As shown in fig. 8, preferably, both side groove walls of the locking groove 331 in the circumferential direction of the rotating shaft 31 are inclined relative to the rotating shaft 31 and the inclination directions of the both side groove walls are opposite, and the groove width of the locking groove 331 gradually increases from the groove bottom to the groove opening; and/or, both sides of the locking convex portion 341 in the circumferential direction of the rotating shaft 31 have inclined surfaces that are inclined relative to the rotating shaft 31, and the inclined surfaces of the both sides are inclined in opposite directions, and the size of the locking convex portion 341 in the circumferential direction of the rotating shaft 31 is gradually reduced from the bottom to the top thereof. The locking recess 331 and/or the locking protrusion 341 are provided with an inclined portion so that one of them slides along the inclined portion of the other as the locking piece 33 and the locking fitting 34 relatively rotate, thereby the locking piece 33 pushes up the locking fitting 34 and further the locking fitting 34 are in a released state, and after the locking piece 33 and the locking fitting 34 stop rotating at a proper position, the locking fitting 34 is pressed to the locking recess 331 and the locking protrusion 341 to be engaged again by the elastic force of the first elastic piece 35, thereby the locking fitting 34 and the locking fitting 34 are in a locked state.

In other embodiments, the member forming the locking recess 331 may be made of an elastic material, and when the locking piece 33 and the locking mating piece 34 rotate relatively, the groove wall of the locking recess 331 deforms elastically, and the locking protrusion 341 can be disengaged from the locking recess 331.

In the embodiment shown in fig. 8, the locking member 33 includes a base fixedly connected to the mounting base 10 and a locking main body portion connected to the base and having four locking recesses 331. The rotatable member 32 has a tubular shape with one closed end and one open end, and the locking main body, the locking mating member 34, and the first elastic member 35 are disposed inside the rotatable member 32. The first resilient member 35 is a compression spring located between the engagement member 34 and the closed end of the rotatable member 32 to apply pressure to the engagement member 34. The locking fitting 34 has four locking protrusions 341 on the side facing the locking piece 33. The rotating shaft 31 is inserted through the locking member 33, the locking mating member 34, the first elastic member 35, and the rotatable member 32.

When the holder 20 and the rotatable member 32 rotate, the locking protrusion 341 of the locking fitting 34 slides along the inclined groove wall of the locking recess 331 of the locking member 33, the locking member 33 pushes up the locking fitting 34 to make them in a disengaged state, after the holder 20 and the rotatable member 32 stop rotating at a proper position, the locking fitting 34 is pressed down until the locking recess 331 of the locking member 33 and the locking protrusion 341 are engaged again under the pressure of the first elastic member 35, so that both are in a locked state, and a certain torsion force exists between the groove wall of the locking recess 331 and the inclined surface of the locking protrusion 341, so that the rotatable member 32 and the rotating shaft 31 are kept fixed. In another embodiment, the first elastic member 35 may apply a pulling force to the locking fitting 34 to pull the locking fitting 34 toward the locking member 33 to tightly fit the locking fitting 34 and the locking member 33.

As shown in fig. 1-7, in some embodiments of the present application, the mounting base 10 of the bracket assembly is a unitary structure with the movable platform body 100. The mounting base 10 is directly fixed to the movable stage body 100 at the manufacturing stage, and the user cannot detach the mounting base from the movable stage body. The carriage assembly is used as an integral part of the movable platform.

Fig. 10 shows a schematic structural view of the carriage assembly (carriage 20 in the stowed position) and the movable platform body 100 of fig. 9. Fig. 11 shows a schematic view of another angle of the carriage assembly and the movable platform body 100 of fig. 10.

Fig. 13 shows a schematic view of another angle of the carriage assembly and the movable platform body 100 of fig. 12.

As shown in fig. 9 to 13, the second embodiment is different from the first embodiment in that the mounting base 10 of the bracket assembly is detachably mounted on the movable platform main body 100. That is, the bracket assembly is used as an accessory to a movable platform that a user can assemble as desired to enable it to perform a carafe mode function and/or for mounting sensors to perform an omni-directional sensing function. When not in use, the user can also detach the bracket component, which is more flexible and convenient.

As shown in fig. 9-13, in some embodiments of the present application, the movable platform is an unmanned aerial vehicle and the movable platform body 100 is a fuselage of the unmanned aerial vehicle. The mounting base 10 comprises a mounting base plate 11 and a connecting frame 12 connected to the mounting base plate 11, the mounting base plate 11 is detachably connected to the bottom of the body, and the support 20 is movably connected to the connecting frame 12. Specifically, the mounting base plate 11 may be mounted at the bottom of the fuselage of the unmanned aerial vehicle by means of screws, snaps, and the like, and the connecting frame 12 and the mounting base plate 11 may also be detachably connected by means of screws, snaps, and the like. The specific structure of the connecting frame 12 and the connecting position with the mounting base plate 11 can be designed reasonably according to the required arrangement position of the bracket 20 and other factors.

For example, as shown in fig. 9 and 10, the connecting frame 12 may have a U-shaped frame shape, both ends of the bottom of the connecting frame 12 are connected to the mounting base plate 11 at both sides of the body, and the top of the connecting frame 12 is used for connecting the bracket 20. At this time, in order to facilitate the installation of the rotation structure 30, the connecting frame 12 may be divided into two parts, i.e., a left part and a right part, which are disposed in a staggered manner, so that an exposed installation step is formed between the two parts, and the rotation structure 30 may be installed at the installation step. In addition, in order to reduce the weight of the entire movable platform after the bracket assembly is installed, a plurality of lightening holes may be provided in the installation base plate 11. The working principle of the bracket assembly of the second embodiment is substantially the same as that of the other structures of the first embodiment, and the description thereof is omitted.

EXAMPLE III

Fig. 14 is an exploded schematic view of the bracket assembly and the movable platform body 100 according to the third embodiment of the present application. Fig. 15 shows a schematic structural view of the carriage assembly (carriage 20 in the stowed position) and the movable platform body 100 of fig. 14. Fig. 16 shows a schematic view of another angle of the carriage assembly and the movable platform body 100 of fig. 15. Fig. 17 shows a schematic structural view of the bracket assembly (with the bracket 20 in the deployed position) and the movable platform body 100 of fig. 14. it should be noted that, in order to facilitate the structure of the sliding part 42, the bracket 20 and the sliding part 42 are not connected in fig. 17, and actually, the sliding part 42 should be connected with the bracket 20 and slide upwards together. Fig. 18 shows a schematic view of another angle of the carriage assembly and the movable platform body 100 of fig. 17.

As shown in fig. 14 to 18, the third embodiment is different from the first embodiment in that a bracket 20 is slidably attached to a mounting base 10. Specifically, the rack assembly further includes a sliding structure 40, through which the rack 20 is slidably connected to the mounting base 10, and a locking structure, through which the rack 20 is held at least in the stored position and the deployed position.

The sliding structure 40 includes a fixed portion 41 and a sliding portion 42 slidable relative to the fixed portion 41. The fixing portion 41 is fixedly connected to the mounting substrate 10, and the sliding portion 42 is fixedly connected to the bracket 20, so that the bracket 20 slides along the mounting substrate 10. In some embodiments of the present application, the sliding structure 40 further includes a second elastic member 43, and one end of the second elastic member 43 is connected to the fixing portion 41, and the other end is connected to the sliding portion 42. When the sliding part 42 and the fixing part 41 slide relatively, the second elastic member 43 can apply an elastic force to the sliding part 42, so that a certain holding force can exist during the sliding process of the sliding part 42 relative to the fixing part 41, and rapid resetting can be facilitated.

In the embodiment shown in the figures, the fixed part 41 is a plate-shaped structure, two sides of which are provided with slide rails, the sliding part 42 is a slider, and the second elastic member 43 is a torsion spring connected between the plate-shaped structure and the slider. Of course, it will be understood by those skilled in the art that the specific forms of the fixed portion 41 and the sliding portion 42 are not limited thereto, and other structures capable of achieving sliding may be used in other embodiments. For example, the fixed part 41 may be a slider, and the sliding part 42 may be a slide rail; alternatively, one of the fixed portion 41 and the sliding portion 42 is a pulley, and the other is a chute.

The locking structure includes an elastic locking member 51 and a lock engagement portion 52. One of the bracket 20 and the mounting base 10 is provided with an elastic lock piece 51, and the other is provided with a lock engagement portion 52. Along with the sliding of the bracket 20, the elastic locking piece 51 can be elastically deformed in a direction away from the locking matching part 52, so that the elastic locking piece 51 and the locking matching part 52 are switched from the locking state to the unlocking state. After the elastic deformation of the elastic locking piece 51 is reset, the elastic locking piece 51 and the locking matching part 52 are switched from the unlocking state to the locking state, so that the bracket 20 is kept at the storage position, the unfolding position or other intermediate positions needing to be stopped.

As shown in fig. 14 to 18, in some embodiments of the present application, the elastic locking member 51 includes an elastically deformable portion 511 and a locking protrusion 512 provided on the elastically deformable portion 511. The lock fitting portion 52 includes a lock hole into which the lock projection 512 is caught. When the bracket 20 starts to slide, the locking protrusion 512 and the locking hole move along with the sliding, and the locking protrusion 512 abuts against and presses against the hole wall of the locking hole to elastically deform the elastically deformable portion 511 in a direction away from the locking engagement portion 52, so that the locking protrusion 512 is disengaged from the locking hole, and the locking state is switched to the unlocking state. When the bracket 20 stops sliding after sliding to a proper position, the elastic deformation of the elastic deformation portion 511 is reset, and the locking protrusion 512 is clamped into the corresponding locking hole again, so that the unlocking state is switched to the locking state.

The locking protrusions 512 and/or the locking holes are provided in plural at intervals in the sliding direction of the holder 20, thereby forming plural locking positions in the sliding direction of the holder 20. Through reasonable design of the plurality of locking positions, the bracket 20 can be selectively stopped and kept at a position (such as an unfolding position, a middle position or a storage position) corresponding to one locking position during sliding, and the use is more flexible.

Of course, it is understood that the manner of locking the elastic locking member 51 and the locking engagement portion 52 is not limited thereto, and in other embodiments, the elastic locking member 51 and the locking engagement portion 52 may also adopt other manners, for example, the locking engagement portion 52 is also a locking convex portion which is engaged with the locking convex portion 512; alternatively, the locking engagement portion 52 extends along the sliding direction of the bracket 20, the elastic locking member 51 includes an elastically deformable portion 511 and a locking protrusion 512, the distance between the locking engagement portion 52 and the elastic locking member 51 is smaller at a position where locking is required, the locking protrusion 512 is compressible with the locking engagement portion 52 to realize locking, the distance between the locking engagement portion 52 and the elastic locking member 51 is larger at a position where locking is not required, and the locking protrusion 512 is separable from the locking engagement portion 52 to realize unlocking.

In the embodiment shown in fig. 14 to 18, the mounting base 10 has a mounting plane, and the periphery of the mounting plane may define a mounting space by providing a limiting frame. The fixing portion 41 of the sliding structure 40 is fixedly connected to the mounting plane by means of glue or the like. Lateral convex parts protruding upwards from the mounting plane are arranged on two sides of the mounting plane. Each side convex part is provided with an accommodating groove, and the groove wall of the accommodating groove close to the installation space is provided with an avoiding hole. The number of the elastic locking pieces 51 is two, and the two elastic locking pieces 51 are respectively arranged in the two accommodating grooves. The locking projection 512 extends into the escape hole. The locking holes are divided into two groups, two sides of the second support 22 are respectively arranged in the two groups of locking holes, each group comprises two locking holes, and the positions of the two locking holes correspond to the accommodating position and the unfolding position of the support 20. When the bracket 20 slides, the locking convex part 512 of one elastic locking piece 51 is locked with one locking hole in each group in a clamping way, so that the bracket 20 is kept at the storage position or the unfolding position. Wherein, the outer surface of the locking protrusion 512 is a cambered surface, thereby facilitating the locking protrusion 512 to be separated from the locking hole when the bracket 20 slides. Of course, in other embodiments, the hole wall of the locking hole may be provided with an inclined guide surface.

In some embodiments of the present application, the bracket assembly further comprises a spacing structure disposed between the bracket 20 and the mounting base 10. The limiting structure is used for limiting the sliding range of the bracket 20 relative to the mounting base 10, and/or is used for enabling the bracket 20 to be positioned to the unfolding position when sliding, and/or is used for enabling the bracket 20 to be positioned to the storage position when sliding.

Specifically, as shown in fig. 14, 17, and 18, the limit structure includes a limit portion 61 and a limit engagement portion 62. The stopper 61 is fixedly connected to the mounting base 10. The position-limiting fitting part 62 is fixedly connected with the bracket 20. The limiting part 61 and the limiting matching part 62 are arranged along the sliding direction of the bracket 20, and when the bracket 20 slides to the limiting matching part 62 to be matched with the limiting part 61 in a limiting way, the bracket 20 stops sliding. It should be noted that the arrangement positions of the limiting part 61 and the limiting matching part 62 can be designed reasonably according to the purpose of limiting. For example, if the stopper structure is used to limit the sliding range of the bracket 20 with respect to the mounting base 10, the stopper portion 61 and the stopper engagement portion 62 should be engaged at both end points of the sliding stroke; if the position limiting structure is used to enable the stand 20 to be positioned to the extended position/the stored position when sliding, the position limiting part 61 and the position limiting matching part 62 should be matched at the position when the stand 20 is positioned at the extended position/the stored position. In addition, the specific form of the limiting structure is not limited to this, and in other embodiments, the limiting structure may also be another limiting structure, for example, the limiting structure includes a limiting convex part disposed on the fixing part 41 of the sliding structure 40, and the limiting convex part is used for being in stop fit with the sliding part 42.

In some embodiments of the present invention, as shown in fig. 14, one of the position-limiting part 61 and the position-limiting matching part 62 has a concave position-limiting surface 611, and the other has a convex position-limiting surface 621 that can fit with the concave position-limiting surface 611. The stopper concave surface 611 and the stopper convex surface 621 are concave-convex in a direction perpendicular to the sliding direction of the holder 20. Spacing is realized through the cooperation of spacing concave surface 611 and spacing convex surface 621, simple structure does benefit to manufacturing to occupation space is less. Of course, it is understood that in other embodiments, the position-limiting part 61 and the position-limiting matching part 62 may have other structures, for example, both the position-limiting part 61 and the position-limiting matching part 62 are position-limiting convex pieces, and both the position-limiting convex pieces contact the position-limiting part.

As shown in fig. 14 and 17, in some embodiments of the present application, the mounting base 10 has a guide groove 71, the position-limiting portion 61 is located in the guide groove 71, the bracket 20 has a guide protrusion 72 slidable along the guide groove 71, and the position-limiting engagement portion 62 is connected to the guide protrusion 72; alternatively, the holder 20 has a guide groove 71, the stopper fitting portion 62 is located in the guide groove 71, the mounting base 10 has a guide projection 72 slidable along the guide groove 71, and the stopper portion 61 is connected to the guide projection 72. The guide protrusion 72 can slide along the guide groove 71 to assist in guiding and provide a relatively hidden installation space for the stopper structure.

In the embodiment shown in fig. 14 to 18, there are two guide grooves 71, and the two guide grooves 71 are provided on the two side projections of the mounting base 10, respectively. The number of the limiting parts 61 is two, each limiting part 61 is in a bent plate shape, one bent part is fixedly connected to the side convex part in a screw mode and the like, the other part extends into the guide groove 71, and the limiting concave surface 611 is located on the part extending into the guide groove 71. The two guide protrusions 72 are provided, and the two guide protrusions 72 are provided on both side surfaces of the second bracket 22, respectively. Each guide convex part 72 is rib-shaped, the limit matching part 62 is arranged at the end part of the guide convex part 72, and the limit convex surface 621 is positioned on the limit matching part 62. The working principle of the bracket assembly of the third embodiment is substantially the same as that of the other structures of the first embodiment, and the description thereof is omitted.

Fig. 19 is an exploded view of the bracket assembly and the movable platform body 100 according to the fourth embodiment of the present application. Fig. 20 shows a schematic structural view of the carriage assembly of fig. 19 (with the carriage in the stowed position) and the movable platform body 100. Fig. 21 shows a schematic view of another angle of the carriage assembly and the movable platform body 100 of fig. 20. Fig. 22 shows a schematic structural view of the carriage assembly of fig. 19 (carriage 20 in the deployed position) and the moveable platform body 100. Fig. 23 shows a schematic view of another angle of the carriage assembly and the movable platform body 100 of fig. 22.

As shown in fig. 19 to 23, the main difference between the fourth embodiment and the third embodiment is that the mounting base 10 of the bracket assembly is detachably mounted on the movable platform main body 100. That is, the bracket assembly is used as an accessory to a movable platform that a user can assemble as desired to enable it to perform a carafe mode function and/or for mounting sensors to perform an omni-directional sensing function. When not in use, the user can also detach the bracket component, which is more flexible and convenient.

As shown in fig. 19-23, in some embodiments of the present application, the movable platform is an unmanned aerial vehicle and the movable platform body 100 is a fuselage of the unmanned aerial vehicle. The mounting base 10 comprises a mounting base plate 11 and a connecting frame 12 connected to the mounting base plate 11, the mounting base plate 11 is detachably connected to the bottom of the body, and the support 20 is movably connected to the connecting frame 12. Specifically, the mounting base plate 11 may be mounted at the bottom of the fuselage of the unmanned aerial vehicle by means of screws, snaps, and the like, and the connecting frame 12 and the mounting base plate 11 may also be detachably connected by means of screws, snaps, and the like. The specific structure of the connecting frame 12 and the connecting position with the mounting base plate 11 can be designed reasonably according to the required arrangement position of the bracket 20 and other factors.

For example, as shown in fig. 19 and 23, the attachment frame 12 may be disposed substantially vertically, with a lower portion of the attachment frame 12 disposed vertically and an upper portion disposed obliquely toward the movable platform body 100. The bottom of the lower portion of the connecting frame 12 is connected to the mounting base plate 11, and the upper portion of the connecting frame 12 is used for connecting the bracket 20. The working principle of the bracket assembly of the fourth embodiment is basically the same as that of the other structures of the third embodiment, and the details are not repeated herein.

The embodiment of the present application further provides a movable platform, which includes a movable platform main body 100 and a bracket assembly, where the bracket assembly is the bracket assembly of the above embodiment. Wherein, the mounting base 10 of the bracket assembly and the movable platform main body 100 are an integral structure, or the mounting base 10 of the bracket assembly is detachably mounted on the movable platform main body 100.

In some embodiments of the present application, the movable platform is an unmanned aerial vehicle or a handheld device. When the movable platform is an unmanned aerial vehicle, the movable platform main body 100 is a fuselage of the unmanned aerial vehicle, the fuselage may have an accommodating groove 101, and when the support 20 of the support assembly is located at the accommodating position, at least a part of the support 20 is located in the accommodating groove 101, so that when the support 20 is located at the accommodating position, the occupied space is smaller, and the movable platform is more concise and attractive. Of course, in other embodiments of the present application, the bracket 20 may also directly engage with the outer surface of the fuselage or have a small space therebetween when in the stowed position.

In the two embodiments shown in fig. 1 to 13, the second bracket 22 can be attached to the end surface of the tail of the body when the bracket 20 is in the storage position. In both embodiments shown in fig. 14-23, the second bracket 22 can be attached to the tail and back of the fuselage near the tail when the bracket 20 is in the stowed position.

For the embodiments of the present application, it should also be noted that, in a case of no conflict, the embodiments of the present application and features of the embodiments may be combined with each other to obtain a new embodiment.
