[0041] In recent years, the technology of unmanned aerial vehicles has been greatly improved, and many intelligent and multifunctional unmanned aerial vehicles have emerged. Most of these unmanned aerial vehicles use remote control to adjust the flight attitude. The use of the buttons on the remote control to control the flight attitude mode is very important and directly affects the safety of the aircraft operation.

[0042] The gear switch provided by the exemplary embodiment of the utility model replaces the toggle button with a push button, so that the remote control can be operated more quickly during use, thereby improving work efficiency.

[0043] It should be noted that the gear switch of the present invention can be used not only in remote controllers of unmanned aerial vehicles, but also in remote controllers of other remote-controlled aircraft, vehicles or various remote-controlled models, and can also be used in any operating device that requires gear switching.

[0044] Figure 1 It is a schematic diagram of the isometric structure of the gear switch according to the embodiment of the utility model; Figure 2 Schematic diagram of the three-dimensional exploded structure of the gear switch according to the embodiment of the utility model. Figure 1 and Figure 2 As shown, the gear switch provided by the exemplary embodiment of the utility model includes a button part 20, a sensing part 30, a base part 10 and at least one magnetic part 22, at least one magnetic part 22 is arranged at a position close to the end of the button part 20; the base part 10 has a cavity, the middle part of the button part 20 is hinged to the base part 10, and the button part and the sensing part 30 are respectively located above and below the bottom wall of the cavity; when the gear switch is in the second gear, there is a second distance between at least one magnetic part 22 and the sensing part 30; when the gear switch is in the first gear, there is a first distance between one of the at least one magnetic part 22 and the sensing part 30; wherein the first distance is smaller than the second distance; the sensing part 30 is used to sense the position of at least one magnetic part 22 to generate a corresponding gear signal.

[0045] In actual applications, the number of magnetic parts 22 can be one or two. When the number of magnetic parts 22 is one, it is arranged at a position close to the end of the button part 20. At this time, by pressing the end of the button part 20, the magnetic part 22 moves toward the sensing part 30 until the distance between the two is the second spacing, and the sensing part 30 generates a gear signal, for example, a first gear signal; and when the other end of the button part 20 is pressed, the magnetic part 22 moves away from the sensing part 30 until the distance between the two is the first spacing, and the sensing part 30 generates a signal that the gear is restored to the second gear, so that the first gear and the second gear can be switched by pressing, that is, the gear switch has two gears.

[0046] When the number of the magnetic members 22 is two, the two magnetic members 22 are respectively located at positions close to the two ends of the button portion 20. Exemplarily, by pressing one end of the button portion 20, the magnetic member 22 at the end moves toward the direction close to the sensing portion 30 until the distance between the two is the second spacing, and the sensing portion 30 generates a first gear signal; at this time, the other end of the button portion 20 is pressed, and the magnetic member 22 moves away from the sensing portion 30 until the distance between the two is the first spacing, and the sensing portion 30 generates a second gear signal; continue to press the other end of the button portion 20, and the magnetic member 22 at the other end moves toward the direction close to the sensing portion 30 until the distance between the two is the third spacing, and the sensing portion 30 generates a third gear signal, and the third spacing can be the same as the first spacing, and the gear switch can be switched between the first gear, the second gear, and the third gear, that is, the gear switch has three gears.

[0047] Exemplarily, the button portion 20 and the base portion 10 are movably connected by a hinge, for example, Figure 1 As shown, two rotating shafts 21 are respectively arranged on both sides of the button portion 20, and two supports with shaft holes are arranged on the upper part of the base portion 10, and each rotating shaft 21 is rotatably arranged in the shaft hole of the corresponding support.

[0048] Based on this, the gear switch of the exemplary embodiment of the utility model can complete the switching of the corresponding gear by pressing the action, avoiding the inconvenience of operation caused by using a toggle switch, which is convenient, fast and more reliable.

[0049] For example, Figure 2As shown, the sensing unit 30 includes two Hall sensors 31, which correspond to two magnetic parts 22 respectively. Each Hall sensor 31 is used to sense the position of the corresponding magnetic part 22 and then generate a current signal. Specifically, the sensing unit 30 also includes a PCBA board. The two Hall sensors 31 are arranged on the surface of the PCBA board facing the base part 10. The PCBA board is also connected to a signal line or an electrical transmission line. When the gear switch is in the second gear, the distance between the two magnetic parts 22 and the corresponding Hall sensors 31 is equal and both are the first distance. At this time, the values ​​sensed by the two Hall sensors 31 are equal, thereby generating a signal of the second gear. The control signal is transmitted to the processing unit for corresponding adjustment.

[0050] Figure 3 Schematic diagram of the isometric structure of the spring piece according to the embodiment of the utility model. Figure 2 and Figure 3 As shown, the gear switch of the exemplary embodiment of the utility model also includes a spring piece 50, which has a middle section 51 and two extension sections 52 respectively connected to the two ends of the middle section 51; the two extension sections 52 are arranged at an obtuse angle, and the two sides of the middle section 51 have protrusions 511, and the two protrusions 511 are respectively arranged in the accommodating grooves of the opposite side walls of the cavity; the gear switch also includes a stop assembly, which includes an elastic member 42, a sliding sleeve 43 and a guide sleeve 41 located in the middle part of the button part, the sliding sleeve 43 is slidably arranged in the guide sleeve 41, one end of the elastic member 42 stops at the bottom of the barrel cavity of the guide sleeve 41, and the other end stops at the bottom of the barrel cavity of the sliding sleeve 43; when the gear switch is in the second gear, the sliding sleeve 43 stops on the middle section 51 through the elastic member 42.

[0051] Exemplarily, the spring piece 50 is made of a metal sheet, which is roughly V-shaped, including two extension sections 52 and a middle section 51 located between the two extension sections 52. Among them, the middle section 51 also has a protrusion 511 on both sides, and correspondingly, there are two accommodating grooves on the two opposite side walls of the cavity, and the two protrusions 511 are respectively accommodated in the two accommodating grooves, and the middle section 51 is close to the bottom wall of the cavity. The two accommodating grooves can form a limit for the spring piece 50 in the extension direction, and at the same time, the freedom of the protrusion 511 in the vertical direction can be not restricted, so that during the movement of the spring piece 50, the protrusion 511 of the middle section 51 can have a certain activity space in the corresponding accommodating groove.

[0052] like Figure 2 As shown, in the stop assembly of the gear switch, the sliding sleeve 43 is slidably arranged in the cylindrical cavity of the guide sleeve 41, and the two are connected by an elastic member 42, such as a spring, and both have a cylindrical cavity for accommodating a part of the spring, thereby limiting the spring.

[0053] When the gear switch is in the second gear, the sliding sleeve 43 stops against the middle section 51 under the action of the spring force. When the gear switch switches to the first gear, the sliding sleeve 43 slides from the middle section 51 of the spring along the extension section 52 to the end of the extension section 52. At this time, under the action of the elastic member 42, the end of the extension section 52 is squeezed and fits on the bottom wall of the cavity, and a collision sound is emitted to remind the operator that the gear switch has been switched to the first gear. For example, when the left end of the button part 20 is pressed and rotated, the elastic member 42 rebounds and drives the sliding sleeve 43 to push the right end of the right extension section 52 of the spring 50 against the right side of the bottom wall of the cavity, and a collision sound is emitted at the same time. The distance between the left magnetic member 22 and the left Hall sensor 31 is reduced, and the Hall induction value, such as the current signal, becomes larger, which indicates that the gear switch is switched to the first gear.

[0054] like Figure 2 As shown, the end of the sliding sleeve 43 facing the elastic sheet 50 can be a spherical crown end; the middle section 51 has a groove 512, and when the gear switch is in the second gear, the sliding sleeve 43 stops in the groove 512.

[0055] The spherical crown end of the sliding sleeve 43 can easily slide back and forth between the extension sections 52 and the middle section 51 of the spring piece 50 without getting stuck. At the same time, a groove 512 is provided on the middle section 51. When the gear switch is in the second gear, the spherical crown end of the sliding sleeve 43 can stop in the groove 512 to form a limit. When no external force is applied or the external force is small, the sliding sleeve 43 is more stable and reliable in the groove 512.

[0056] For example, Figure 3 As shown, the free end of each extension section 52 has a bent portion 521; when the gear switch is in the first gear or the third gear, the bent portion 521 is attached to the bottom wall of the cavity through the sliding sleeve 43. When the gear switch is in the first gear or the third gear, the sliding sleeve 43 can slide onto the bent portion 521 through the extension section 52 of the spring 50. The bent portion 521 can prevent the sliding sleeve 43 from easily sliding along the extension section 52 toward the middle section 51, and play a role in limiting the sliding sleeve 43, thereby making the gear switch more reliable. The bent portion 521 is bent relative to the extension section 52 toward the bottom wall of the cavity, and forms a section that is consistent with the extension direction of the extension section 52.

[0057] Figure 4 : is a schematic diagram of the isometric structure of the button portion according to an embodiment of the utility model; Figure 2 and Figure 4As shown, when the gear switch is in the first gear or the third gear, one of the two magnetic members 22 is opposite to the corresponding Hall sensor 31. When each of the two magnetic members 22 is close to the corresponding Hall sensor 31, for example, when the distance between the two is the first distance, the magnetic member 22 is opposite to the Hall sensor 31; and when the gear switch is in the second gear, each magnetic member 22 is not vertically downward, but extends obliquely toward the two ends of the button part 20 along the direction toward the bottom wall of the cavity, so that the gear switch can be in the first gear or the third gear, and the magnetic member 22 is opposite to the corresponding Hall sensor 31.

[0058] For example, when the gear switch is in the second gear, the magnetic member 22 can also be vertically downward, that is, each magnetic member 22 is opposite to the bottom wall of the cavity; and when the gear switch is in the first gear or the third gear, each magnetic member 22 is not opposite to the corresponding Hall sensor 31 but is tilted at a certain angle, but the Hall sensor 31 can still generate a gear signal. Based on this, the arrangement of the magnetic member 22 can reduce the size of the button part 20, making the entire gear switch structure more compact.

[0059] In some embodiments, Figure 4 As shown, at least one position near the end of the button part 20 is provided with a fixing sleeve 23, and at least part of each magnetic member 22 is embedded in the corresponding fixing sleeve 23. Exemplarily, the button part 20 is provided with two fixing sleeves 23 near the end, respectively, for fixing the magnetic member 22, which can be a magnet, and a fixing rod adapted to the sleeve of the fixing sleeve 23 is connected to the magnet, and the fixing rod can be fixedly connected to the sleeve of the fixing sleeve 23 by glue or the like, which can provide positioning for the magnetic member 22 on the one hand, and make the connection between the magnetic member 22 and the button part 20 more firm and reliable on the other hand.

[0060] Figure 5 Schematic diagram of the isometric structure of the remote control housing according to the embodiment of the present utility model. Figure 5 As shown, the remote controller provided by the exemplary embodiment of the present utility model includes a housing 60 and the above-mentioned gear switch, and the housing 60 may be the outer shell of the remote controller.

[0061] Figure 6 yes Figure 5 A magnified view of part A. Figure 5 and Figure 6 As shown, the shell 60 has a first opening 63 and a clamping portion 62 surrounding the first opening 63 and protruding from the inner wall of the shell 60, and the gear switch is connected to the shell 60 through the first opening 63; the base portion 10 has a second opening 11 and a fixing groove 12 surrounding the second opening 11, and the clamping portion 62 is used to press the waterproof ring 61 in the fixing groove 12.

[0062] The base portion 10 of the gear switch is located inside the housing 60, and since the housing 60 has a pressing portion 62 of a shell-like structure inside, the base portion 10 can be fixed to the inner wall of the housing 60 by screw connection, and the pressing portion 62 can cooperate with the fixing groove 12 surrounding the second opening 11 on the base portion 10, and a silicone waterproof ring 61 can be provided in the fixing groove 12 of the base portion 10. Based on this, the pressing portion 62 presses the silicone waterproof ring 61 tightly in the fixing groove 12 of the base portion 10 to form a waterproof structure. At the same time, since the magnetic member 22 of the button portion 20 does not directly contact the Hall sensor 31 of the sensing portion 30, that is, the button portion 20 and the sensing portion 30 are respectively located on both sides of the bottom wall of the cavity, water from the external environment cannot flow into the interior of the housing 60. Based on this, the remote controller provided by the exemplary embodiment of the utility model has an overall waterproof performance, which improves the reliability and operation safety of the remote controller.
