Description

Technical Field

[0001] This utility model relates to the field of joystick technology, and in particular to a joystick assembly that can automatically return to center. Background Technology

[0002] The joystick is an important component of a drone remote controller, primarily used to control the drone's flight attitude and trajectory. In addition, some drone joysticks can be combined with other function buttons to achieve more operations. For example, the DJI Ascension joystick, when used with related equipment, allows you to control the aircraft's ascent, descent, or horizontal movement by moving the joystick. Combined with the throttle trigger, it can also enable the aircraft to perform cool maneuvers such as forward / backward somersaults, left / right somersaults, or 180° drifts. Furthermore, pressing specific buttons can also be used to operate the flight goggles' screen menu, facilitating adjustments to camera parameters and other settings.

[0003] Currently, most joysticks on the market use a compression spring structure for automatic centering. This structure is relatively complex, which is not conducive to assembly and reducing production costs. The difference in parallelism between the upper and lower planes of the compression spring can lead to a large centering error. Utility Model Content

[0067] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0068] Please see Figure 1-6 A joystick assembly that can automatically return to center includes a base 1, on which a first support 19 and a second support 20 are connected.

[0069] A lower rocker arm 2 is rotatably connected to the first support base 19. An upper rocker arm 3 is rotatably connected to the second support base 20.

[0070] The lower rocker arm 2 is rotatably connected to the first support base 19 with the x-axis as the rotation axis. The upper rocker arm 3 is rotatably connected to the second support base 20 with the y-axis as the rotation axis, and the upper rocker arm 3 is located above the lower rocker arm 2.

[0071] like Figure 4 As shown, the central shafts at both ends of the lower rocker arm 2 are respectively connected to the two central holes of the first support base 190.

[0072] like Figure 4 As shown, the two ends of the upper rocker arm 2 are connected to the two central holes of the second support base 20 respectively.

[0073] The upper rocker arm 3 is provided with a rocking hole 301 that runs vertically through it. The rocking hole 301 is located above the lower rocker arm 2 and corresponds to the lower rocker arm 2. The rocking hole 301 extends along the x-axis.

[0074] This rocker assembly also includes a rocker handle 4, the lower end of which passes downward through the rocking hole 301 and is rotatably connected to the lower rocker arm 2. The lower end of the rocker handle 4 is rotatably connected to the lower rocker arm 2 with the y-axis as the rotation axis.

[0075] With the help of the rotation of the lower rocker arm 2, the rotation of the upper rocker arm 3, and the extension of the rocking hole 30, the rocker arm 4 can be rocked along the x-axis and / or y-axis.

[0076] When the crank handle 4 is cranked only along the y-axis, the extension of the cranking hole 301 allows only the lower rocker arm 2 to rotate. When the crank handle 4 is cranked only along the x-axis, the lower end of the crank handle 4 is rotatably connected to the lower rocker arm 3, allowing only the upper rocker arm 2 to rotate.

[0077] In this embodiment, a first swing arm 5 corresponding to the lower rocker arm 2 is rotatably connected to the first support base 19. A second swing arm 6 corresponding to the upper rocker arm 3 is rotatably connected to the second support base 20.

[0078] One end of the first swing arm 5 is rotatably connected to the first support base 19 via the first rotating shaft 18, and is rotatably connected to the first support base 19 with the x-axis as the rotation axis.

[0079] One end of the second swing arm 6 is rotatably connected to the second support base 20 via the second rotating shaft 20, and is rotatably connected to the second support base 20 with the y-axis as the rotation axis.

[0080] In this embodiment, the rocker assembly further includes a first tension spring and a second tension spring.

[0081] One end of the first tension spring 7 is connected to the first support base 19, and the other end of the first tension spring 7 is connected to the other end of the first rocker arm 5. The first tension spring 7 is configured to apply an elastic tension to the first rocker arm 5 so that the first rocker arm 5 rotates to approach or abut against the lower rocker arm 2.

[0082] The lower rocker arm 2 is connected to a first pressing part 201 and a second pressing part 202, which correspond to the first rocker arm 5.

[0083] When the lower rocker arm 2 rotates from the center position in a clockwise (or forward) direction, the first pressing part 201 is driven by the lower rocker arm 2 to push open the first swing arm 5, causing the first swing arm 5 to rotate away from the lower rocker arm 2.

[0084] When the lower rocker arm 2 rotates from the center position in a counterclockwise (or reverse) direction, the second pressing part 202 is driven by the lower rocker arm 3 to push open the first swing arm 5, causing the first swing arm 5 to rotate away from the lower rocker arm 2, and the first tension spring 7 provides the elastic tension for return.

[0085] Thus, by means of a first tension spring 7, the lower rocker arm 2 can be returned to its original position (center position) after rotating clockwise and after rotating counterclockwise.

[0086] Similarly, one end of the second tension spring 8 is connected to the second support 20, and the other end of the second tension spring 8 is connected to the other end of the second rocker arm 6. The second tension spring 8 is configured to apply an elastic tension to the second rocker arm 6 so that the second rocker arm 6 rotates to approach or abut against the upper rocker arm 3.

[0087] The upper rocker arm 3 is connected to a third pressing part 302 and a fourth pressing part, which correspond to the second rocker arm 6.

[0088] When the upper rocker arm 3 rotates clockwise (or forward) from the center position, the third pressing part 302 is driven by the upper rocker arm 3 to push open the second swing arm 6, causing the second swing arm 6 to rotate away from the upper rocker arm 3.

[0089] When the upper rocker arm 3 rotates from the center position to the counterclockwise direction (or the opposite direction), the fourth pressing part is driven by the upper rocker arm 3 to push open the second swing arm 6, causing the second swing arm 6 to rotate away from the upper rocker arm 3, and the second tension spring 8 provides the elastic tension for return.

[0090] Thus, by using a second tension spring 8, the upper rocker arm 3 can be returned to its original position (center position) after rotating clockwise and counterclockwise.

[0091] In this embodiment, the above-described structure enables independent and coordinated rotation along two different axes, and only one first tension spring 7 and one second tension spring 8 are needed to achieve automatic return after multi-directional rotation. The overall structure is simpler.

[0092] In some embodiments, a first rotation detection component is provided between the lower rocker arm 3 and the base 1 to detect the rotational position of the lower rocker arm 3.

[0093] In some embodiments, the first rotation detection component includes a first magnet 9 mounted on the lower rocker arm 3 and a first Hall chip 10 mounted on the base 1 and corresponding to the first magnet 9.

[0094] When the lower rocker arm 2 rotates, it drives the first magnet 9 to rotate. The first Hall chip 10 can output a detection signal indicating the current rotation position of the lower rocker arm 2 by detecting the rotation of the first magnet 9.

[0095] In some embodiments, a second rotation detection component is provided between the upper rocker arm 3 and the base 1 to detect the rotation position of the upper rocker arm 3.

[0096] In some embodiments, the second rotation detection component includes a second magnet 11 mounted on the upper rocker arm 2 and a second Hall chip 12 mounted on the base 1 and corresponding to the second magnet 11.

[0097] When the upper rocker arm 3 rotates, it drives the second magnet 11 to rotate. The second Hall chip 12 can output a detection signal indicating the current rotation position of the upper rocker arm 3 by detecting the rotation of the second magnet 11.

[0098] Specifically, the upper rocker arm 2 and the lower rocker arm 3 drive the corresponding magnets to move, thereby inducing the Hall chip through magnetic field. The Hall chip receives different magnetic flux magnitudes and outputs different voltage values ​​after calculation.

[0099] In some embodiments, the linear Hall sensor input voltage of the first rotation detection component and / or the second rotation detection component is DC2.5~5V, corresponding to an output of DC0~VDDV. The magnitude of the output voltage is proportional to the magnetic field, and the ratio is as follows:

[0100]

[0101] Because of its linear output, the design takes into account that the applied voltage, temperature, and sensitivity are the same for both the NS and p-fields. The linearity is calculated for the applied magnetic fields in both the positive and negative directions, and the calculation formulas are as follows:

[0102]

[0103] and

[0104]

[0105] In some embodiments, the Hall chips (first Hall chip 10 and second Hall chip 12) have built-in foolproof circuits to ensure output stability.

[0106] In some embodiments, the rocker assembly further includes a protective housing 13 having an actuation hole 14 corresponding to the rocker arm 4.

[0107] The protective housing 13 is connected to the base 1 and is fitted onto the crank handle 4 through the movable hole 14. The crank handle 4 can be rocked along the x-axis and along the y-axis through the gap left in the movable hole 14.

[0108] In some embodiments, the protective housing 13 has a rocking extension groove 15 that is recessed along the position of the corresponding movable hole and cooperates with the rocker handle. The rocking extension groove 15 can increase the rocking range of the rocker handle 4. On the other hand, when the rocker handle 4 is rocked to enter the rocking extension groove 15, the groove wall of the rocking extension groove 15 can be used to restrict the rocker handle 4 from rocking in other directions, thereby forming a directional rocking setting during this rocking stroke.

[0109] For example, it has an x-axis rocking extension groove 15a that is engaged with the rocking handle rocking along the x-axis, and a y-axis rocking extension groove 15b that is engaged with the rocking handle rocking along the y-axis.

[0110] When the crank 4 is rocked along the x-axis and the crank 4 does not enter the x-axis rocking extension groove 15a, the crank 4 can also rock along the y-axis; after the crank 4 is rocked along the x-axis and the crank 4 enters the x-axis rocking extension groove 15a and is oriented by the x-axis rocking extension groove 15a, the crank 4 is restricted to not being able to rock along the y-axis, and an x-axis oriented rocking setting is formed in the rocking stroke within the x-axis rocking extension groove 15a.

[0111] like Figure 2 , 3 As shown, in some embodiments, the movable hole 14 is square, and all four sides of the movable hole 14 are recessed to obtain a corresponding rocking extension groove.

[0112] In some embodiments, the upper end of the crank 4 extends through the movable hole 14 into the protective housing 13.

[0113] This joystick assembly also includes a dust cover 16, which is fitted onto the upper end of the joystick 4 and forms a cover for the movable hole 14.

[0114] In some embodiments, the upper end of the crank handle 4 is also connected to a handle head 17, which is used to block the dust cover 16 to prevent the dust cover 16 from coming off the crank handle upward.

[0115] In some embodiments, the handle head 17 is provided with anti-slip features, such as anti-slip textures, anti-slip protrusions, chemical-resistant grooves, etc., so that the user can shake the handle by operating the handle head.

[0116] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
