Description

Technical Field

[0001] The present application relates to the field of drone control technology, and in particular to a remote controller and a drone system. Background Art

[0002] An unmanned aerial vehicle (UAV), also known as a drone, is an unmanned aircraft controlled by a compatible remote control. Specifically, the remote control wirelessly transmits commands to the drone, controlling its movements and the operation of other devices onboard. For example, a display device such as a mobile phone or tablet is often attached to the remote control to allow for immediate viewing of camera footage. However, conventional remote controls typically use a single-sided clamp to hold a display device such as a mobile phone or tablet, which can cause the display device to fall from the remote control and be damaged.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.

[0049] Technologies, methods and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods and equipment should be considered part of the authorization specification.

[0050] In the description of this application, it should be noted that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0051] In the description of this application, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0052] The technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0053] Figure 1 A schematic structural diagram of a remote control provided in one embodiment of the present application when in a storage state; Figure 2 for Figure 1 The schematic diagram of the structure of the remote control when it is in the unfolded state is shown. Figure 3 for Figure 1 The exploded view of the remote control is shown.

[0054] First, please see Figure 1-Figure 3 The remote control includes: a housing assembly 1, a synchronization mechanism 2, and a reset mechanism 3; the housing assembly 1 includes a first housing 11, a second housing 12, and a third housing 12, wherein the second housing 12 and the third housing 12 are respectively located on opposite sides of the first housing 11, and the second housing 12 and the third housing 12 are both slidably connected to the first housing 11; the synchronization mechanism 2 is disposed within the first housing 11, and when the second housing 12 slides relative to the first housing 11, the synchronization mechanism 2 drives the third housing 12 to slide synchronously in the opposite direction; the reset mechanism 3 is configured to reset when both the second housing 12 and the third housing 12 slide in a direction away from the first housing 11. It should be noted that the aforementioned "sliding connection" means between two components that are directly or indirectly connected, wherein one component can move relative to the other component in a specific direction.

[0055] The remote control can be switched between a stowed state and an unfolded state. In the stowed state, the second shell 12 and the third shell 12 are both against the first shell 11; in the unfolded state, the reset mechanism 3 can provide opposing forces so that the second shell 12 and the third shell 12 can jointly clamp the display terminal. In the remote control involved in this application, the second shell 12 and the third shell 12 slide synchronously in opposite directions under the coordinated action of the synchronization mechanism 2 and the reset mechanism 3. Compared with the second shell 12 or the third shell 12 clamping the display terminal on one side, the second shell 12 and the third shell 12 clamping on both sides can provide more support for the display terminal, thereby increasing the contact area between the display terminal and the second shell 12 and the third shell 12, and reducing the sliding or movement between the three stress points, thereby reducing the probability of the display terminal falling when loaded on the remote control. In addition, after the display terminal is loaded on the remote control, it will always be in the middle position, that is, the weight of each area of the remote control is evenly distributed, which can also reduce the hand-held fatigue caused by the center of gravity shifting to one side after the display terminal is loaded on the remote control.

[0056] It should be noted that the distance between the second shell 12 and the third shell 12 in the retracted state is smaller than the distance between the second shell 12 and the third shell 12 in the unfolded state. Thus, a clamping space that is adapted to the size of the display terminal can be defined between the second shell 12 and the third shell 12 to jointly clamp the aforementioned display terminal.

[0057] It should also be noted that the display terminal mentioned here specifically refers to a display terminal with a user interface. A "user interface" is a medium through which a user can interact with an electronic device. It displays visual information such as images and text when powered on, and also provides functions such as data entry, data modification, and data review. Furthermore, the user interface constituted by the display terminal is not part of the aforementioned remote control; that is, the display terminal is not a component of the remote control provided in this application.

[0058] For ease of description, the embodiments of this application are illustrated using a mobile phone as an example of a display terminal. It is understandable that the display terminal can also be a tablet, a display with a built-in power supply, or other display terminals that support a user interaction interface other than a mobile phone.

[0059] The first housing 11 defines a receiving space (not shown) that accommodates the synchronization mechanism 2, the reset mechanism 3, and components such as the circuit board described below. The first housing 11 defines a first opening 1111 and a second opening 1121, both of which communicate with the receiving space. The second housing 12 can slide through the first opening 1111 within the receiving space and connect to the first housing 11. The third housing 12 can slide through the second opening 1121 within the receiving space and connect to the second housing 12.

[0060] Please combine Figure 9 See also Figure 3 In some embodiments, the first housing 11 includes a first sub-housing 111 and a second sub-housing 112 .

[0061] The first sub-shell 111 is generally a frame with an open top, and its cross section is generally U-shaped. A first opening 1111 and a second opening 1121 are respectively formed on two opposite side walls of the first sub-shell 111 .

[0062] The bottom of the first sub-shell 111 is provided with a first guide groove 113, a second guide groove 114, and a gear groove 115. The first guide groove 113 and the second guide groove 114 are spaced apart, with the opposite ends of the first guide groove 113 being respectively enclosed by the sidewall where the first opening 1111 and the sidewall where the second opening 1121 are located. Similarly, the opposite ends of the second guide groove 114 are also respectively enclosed by the sidewall where the first opening 1111 and the sidewall where the second opening 1121 are located. The first guide groove 113 and the second guide groove 114 extend in a direction perpendicular to the direction from the first opening 1111 to the second opening 1121.

[0063] The gear groove 115 is arranged between the first guide groove 113 and the second guide groove 114 and is respectively connected to the first guide groove 113 and the second guide groove 114. A gear shaft is protruded from the middle part of the gear groove 115, and the gear shaft is used to position and install the gear 21 of the synchronization mechanism 2 to be described in detail below.

[0064] The second sub-shell 112 is roughly in the shape of a cover, and its cross-section is roughly in the shape of an inverted U. The second sub-shell 112 is screwed and fixed to the first sub-shell 111, and together with the first sub-shell 111, it defines the aforementioned receiving space. Furthermore, the second sub-shell 112 is also snap-connected to the first sub-shell 111, so that the second sub-shell 112 and the first sub-shell 111 can be pre-positioned on the screw holes and nut columns on the two through the snap-connection, so as to improve the assembly efficiency of the remote control. Of course, the connection method between the second sub-shell 112 and the first sub-shell 111 is not limited to this. In addition to screwing and snap-connection, detachable connections such as plug-in, bonding or snap-fitting can also be used to achieve fixation between the two, which will not be described in detail here.

[0065] The surface of the second sub-housing 112 facing away from the first sub-housing 111 is substantially flat, so as to provide support for the display terminal.

[0066] The second shell 12 is slidably connected to the first shell 11 and has a first clamping surface 1211 . The first clamping surface 1211 is used to cooperate with a second clamping surface 1311 of the third shell 12 to be described below.

[0067] Please combine Figure 9 See also Figure 3In some embodiments, the second shell 12 includes a first gripping portion 121 and a first sliding portion 122 .

[0068] The first grip portion 121 is a hollow structure, which is formed to fit the ergonomic shape of a user's hand when held. The first grip portion 121 can accommodate the first joystick 52 module and the first battery of the battery assembly, which will be described in detail below.

[0069] The first sliding portion 122 is formed to protrude outward from one side of the first gripping portion 121, and its cross-sectional shape matches the shape of the first opening 1111. The first sliding portion 122 passes through the first opening 1111 and is slidably connected to the first housing 11 within the receiving space.

[0070] The first sliding portion 122 is a partially hollow structure having a first channel 122 a connected to the receiving space and the first gripping portion 121 . The first channel 122 a is used to receive the first elastic member 31 of the reset mechanism 3 to be described below.

[0071] A first clamping surface 1211 is formed at the connection between the first sliding portion 122 and the first gripping portion 121. Preferably, the first clamping surface 1211 is a stepped surface.

[0072] To reduce the possibility of the second housing 12 falling out of the first housing 11, in some embodiments, a first limiting protrusion is provided at the bottom end of the first sliding portion 122 away from the first gripping portion 121. The bottom of the first sub-housing 111 defines a first limiting groove corresponding to the first limiting protrusion, and the first limiting protrusion is embedded in the first limiting groove.

[0073] like Figures 1 to 3 or Figure 9 As shown, in order to reduce the occurrence of the display terminal being loaded on the remote control and falling out of the second shell 12, in some embodiments, a side surface of the first gripping portion 121 adjacent to the first clamping surface 1211 partially protrudes toward the first shell 11 to form a first buckle position 1212, which is in close contact with the remote control when the display terminal is loaded on the remote control, thereby reducing the occurrence of the display terminal being loaded on the remote control and falling out of the second shell 12.

[0074] To increase the friction between the display terminal and the remote control, in some embodiments, a rubber sheet (not shown) with a certain roughness is attached to the first clamping surface 1211 , and the rubber sheet is configured to contact a side surface of the display terminal.

[0075] As for the third shell 12, the third shell 12 is slidably connected to the first shell 11, and the third shell 12 has a second clamping surface 1311, which cooperates with the first clamping surface 1211. When the remote control is in the unfolded state, the first clamping surface 1211 and the second clamping surface 1311 jointly clamp the aforementioned display terminal.

[0076] Please combine Figure 8 See also Figure 3 In some embodiments, the third shell 12 includes a second gripping portion 131 and a second sliding portion 132 .

[0077] The second grip portion 131 is a hollow structure, ergonomically designed to fit the user's other hand. The second joystick 62 module and the second battery of the battery assembly, described below, can be housed within the second grip portion 131. Preferably, the second grip portion 131 and the first grip portion 121 are arranged in mirror-image symmetry.

[0078] The second sliding portion 132 protrudes outward from the second gripping portion 131 toward the first housing 11, and its cross-sectional shape matches the shape of the second opening 1121. The second sliding portion 132 passes through the second opening 1121 and is slidably connected to the first housing 11 within the receiving space.

[0079] The second sliding portion 132 is a partially hollow structure having a third channel 132 a connected to the receiving space and the second gripping portion 131 . The third channel 132 a is used to receive the second elastic member 32 of the reset mechanism 3 to be described below.

[0080] A second clamping surface 1311 is formed at the connection between the second sliding portion 132 and the second gripping portion 131. Preferably, the second clamping surface 1311 is a stepped surface.

[0081] To reduce the possibility of the third housing 12 falling out of the first housing 11, in some embodiments, a second limiting protrusion (not shown) is provided at the bottom end of the second sliding portion 132 away from the second gripping portion 131. The bottom of the second sub-housing 112 defines a second limiting groove (not shown) corresponding to the second limiting protrusion, and the second limiting protrusion is embedded in the second limiting groove.

[0082] like Figures 1 to 3 or Figure 8 As shown, in order to reduce the occurrence of the display terminal being loaded on the remote control and falling out of the third shell 12, in some embodiments, a side surface of the second gripping portion 131 adjacent to the second clamping surface 1311 protrudes toward the first shell 11 to form a second buckle 1312, which is in close contact with the remote control when the display terminal is loaded on the remote control, thereby reducing the occurrence of the display terminal being loaded on the remote control and falling out of the third shell 12.

[0083] In some embodiments, to increase the friction between the display terminal and the remote controller, a rough rubber sheet is attached to the second clamping surface 1311 , and the rubber sheet is configured to contact the other side surface of the display terminal.

[0084] For synchronization mechanism 2, please combine Figures 7 to 9 See also Figure 4 In some embodiments, it includes a gear 2, a first rack 22, and a second rack 23. Gear 2 is sleeved on the gear 2 axis and can rotate relative to the gear 2 axis. Of course, gear 2 can also be suspended in the air, and is restrained by the first rack 22 and the second rack 23 due to its meshing with the first rack 22 and the second rack 23.

[0085] The first rack 22 is connected to the second housing 12. Preferably, the first rack 22 is threadedly fixed to the end of the first sliding portion 122 away from the first gripping portion 121. The first rack 22 is movably embedded in the first guide groove 113 and meshes with the gear 2. It is understood that the connection method between the first rack 22 and the first sliding portion 122 can be adaptively adjusted according to actual circumstances and is not specifically limited here. For example, the first rack 22 can be adhesively fixed to the first sliding portion 122.

[0086] In some embodiments, the open side of the first guide groove 113 is covered by the second sliding portion 132 .

[0087] The second rack 23 is connected to the third housing 12. For example, the second rack 23 is threadedly secured to the end of the second sliding portion 132 distal from the second gripping portion 131. The second rack 23 is movably embedded in the second guide slot 114 and meshes with the gear 21. The connection between the second rack 23 and the second sliding portion 132 is similar to the connection between the first rack 22 and the second sliding portion 132. Please refer to the aforementioned description of the first rack 22 and the first sliding portion, and will not be further elaborated here.

[0088] In some embodiments, the open side of the second guide groove 114 is covered by the first sliding portion 122 .

[0089] The advantage of the rack and pinion transmission used in the synchronization mechanism 2 of the present application is that, compared with the worm gear transmission or the track transmission, the rack and pinion transmission has the characteristics of compact structure and low torque transmission loss. While reducing the space occupied by the synchronization mechanism 2, it can still provide stable torque so that the first clamping surface 1211 and the second clamping surface 1311 can jointly clamp the display terminal.

[0090] Alternatively, in other embodiments, the synchronization mechanism 2 may employ a worm gear transmission. For example, the synchronization mechanism 2 may include a first worm, a second worm, and a turbine. The first worm is fixed to the first sliding portion 122 and is arranged along the sliding direction of the first sliding portion 122. The second worm is fixed to the second sliding portion 132 and is arranged along the sliding direction of the second sliding portion 132. The worm gear is disposed between the first and second worms and meshes with both the first and second worms.

[0091] Alternatively, in other embodiments, the synchronization mechanism 2 may employ a synchronous toothed belt drive. For example, the synchronization mechanism 2 may include a first toothed belt, a second toothed belt, and a gear. The first toothed belt is fixed to the first sliding portion 122 and extends along the sliding direction of the first sliding portion 122. The second toothed belt is fixed to the second sliding portion 132 and extends along the sliding direction of the second sliding portion 132. The gear is disposed between the first and second toothed belts and meshes with both the first and second toothed belts.

[0092] The reset mechanism 3 includes a first elastic member 31, one end of the first elastic member 31 is connected to the first housing 11, and the other end of the first elastic member 31 is connected to the second housing 12. Figure 4 As shown, in some embodiments, one end of the first elastic member 31 is fixed to a fixing post on the first sub-shell 111, and the other end of the first elastic member 31 passes through the first channel 122a and is fixed to the first grip portion 121. The first elastic member 31 has an initial deformation so that when the second shell 12 and the third shell 12 are in the initial position, the first elastic member 31 has a certain elastic restoring force to abut the first grip portion 121 against the first opening 1111 and the second grip portion 131 against the second opening 1121. In other words, the remote control is now in the stowed state. Subsequently, the second shell 12 and the third shell 12 slide synchronously in opposite directions under the action of the synchronization mechanism 2, and the first elastic member 31 is stretched, thereby increasing the elastic restoring force for resetting the first grip portion 121 and the second grip portion 131. As an example, the first elastic member 31 may be a spring. Of course, the first elastic member 31 may also be another elastic member with elastic force, such as a rubber band.

[0093] Preferably, the number of the first elastic members 31 is two, and accordingly, the number of the first channels 122a is also two, and the two first channels 122a are respectively located on opposite sides of the first sliding portion 122 along its width direction. Figure 4As shown, in some embodiments, one end of a first elastic member 31 is fixed to a fixing post on the first sub-case 111, and the other end of the first elastic member 31 passes through a first channel 122a and is fixed to a first gripping portion 121. One end of another first elastic member 31 is fixed to another fixing post on the first sub-case 111, and the other end of another first elastic member 31 passes through another first channel 122a and is fixed to another first gripping portion 121.

When the second housing 12 and the third housing 12 are in their initial positions, the second elastic member 32 pre-exists a certain elastic restoring force. The second elastic member 32 and the first elastic member 31 jointly abut the first grip portion 121 against the first opening 1111 and the second grip portion 131 against the second opening 1121. In other words, the remote control is now in the stowed state. Subsequently, the second housing 12 and the third housing 12 slide synchronously in opposite directions under the action of the synchronization mechanism 2, and the second elastic member 32 and the first elastic member 31 are stretched together, thereby increasing the elastic restoring force for resetting the first grip portion 121 and the second grip portion 131. As an example, the second elastic member 32 may be a spring. Of course, the second elastic member 32 may also be another elastic member with elastic force, such as a rubber band.

[0095] Preferably, the number of the second elastic members 32 is two, and accordingly, the number of the third channels 132a is also two, and the two third channels 132a are respectively located on opposite sides of the second sliding portion 132 along its width direction.

One end of another second elastic member 32 is fixed to another fixing post on the second sub-case 112, and the other end of another second elastic member 32 passes through another third channel 132a and is fixed to another second gripping portion 131.
