[0002] A joystick is a physical device that converts the movement of a plastic rod into electronic information that a computer can process. Its basic principle is to convert the movement of the plastic rod into electronic information that a computer can process. It is widely used in various mechanical equipment, including jet fighters, excavators, wheelchairs, and other devices across various industries. In existing joystick devices, operation is generally purely manual. However, situations often arise where the joystick needs to continuously control a specific direction, necessitating the use of a locking mechanism to save manpower.

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figure 1 , Figure 4 and Figure 6This utility model provides an embodiment of a locking structure for a multi-directional joystick, comprising a housing 1 and an outer sleeve 2. A connecting ring 3 is fixedly connected to the inner wall of the outer sleeve 2, a fixing sleeve 5 is fixedly connected to the inner wall of the connecting ring 3, an adjusting rod 4 is slidably connected to the inner wall of the fixing sleeve 5, a top rod 6 is fixedly connected to the outer wall of the adjusting rod 4, a retaining ring 7 is fixedly connected to the inner wall of the fixing sleeve 5, a rotating core 8 is movably connected to the inner wall of the retaining ring 7, a functional rod 13 is fixedly connected to the outer wall of the rotating core 8, an insertion rod 15 is fixedly connected to one end of the functional rod 13, a plurality of limiting plates 24 are fixedly connected to the inner wall of the housing 1, a slider 14 is slidably connected to the inner wall of one of the limiting plates 24, a spring 16 is sleeved on the outer wall of the insertion rod 15, and a locking assembly is provided inside the housing 1.

[0028] Specifically, the outer shell 1 and the outer sleeve 2 provide protection and support for the internal components. By default, this joystick is in a real-time self-locking mode. The upper rod-shaped structure engages with the locking rod 17 via the insertion rod 15. Operating the upper part will activate the lower self-locking mechanism. This structure is only triggered when switching to a non-self-locking mode. Pressing the outer sleeve 2 causes the internal adjusting rod 4 to press the top rod 6 fixedly connected to one end of the adjusting rod 4, which is then moved to slide synchronously. The sliding is limited by the fixing sleeve 5. When the adjusting rod 4 and the top rod 6 slide together, the top rod 6 will push the rotating core 8 at its other end to slide synchronously. In the default state, multiple protrusions 10 fixed on the outer wall of the rotating core 8 are located in the grooves 12 on the outer wall of the retaining ring 7. When the rotating core 8 is pushed, the protrusions 10 gradually slide along the grooves 12. When they slide out, the protrusions 10 continue to slide along the inclined outer wall of the retaining ring 7. This causes the rotating core 8 to rotate until it slides into the outer wall of the slide groove 11. When the rotating core 8 is pushed, the functional rod 13, which is fixedly connected to one end of the rotating core 8, will also be driven to slide. The functional rod 13 gradually compresses the spring 16. When the protrusion 10 moves from the shallower slot 12 to the deeper slide groove 11, the spring 16 loses its compressive force and drives the front component to retract through stress, causing the insertion rod 15 driven by the other end of the functional rod 13 to disengage from the locking rod 17 slot. At this time, operating the upper rod structure will not trigger the locking.

[0029] Reference Figure 2 , Figure 7 and Figure 8The locking assembly includes multiple fixing blocks 18, all of which are fixedly connected to the inner wall of the outer casing 1. A rotating column 19 is rotatably connected to the inner wall of the fixing block 18. A rotating frame 20 is fixedly connected to the opposite side of two rotating columns 19. Multiple locking rings 21 are fixedly connected to the inner wall of the outer casing 1. An inner core 22 is fixedly connected to the outer wall of the rotating column 19. A locking plate 23 is provided on the outer wall of the inner core 22. A universal joint is installed on the inner wall of the outer casing 1. A locking rod 17 is fixedly connected to the top of the universal joint. The inner core 22 is slidably connected to the outer wall of the locking ring 21. Multiple engaging grooves are opened on the outer wall of the inner core 22. The locking plate 23 is installed in the engaging grooves. The inner wall of the locking ring 21 is provided with internal teeth. The outer wall of the locking plate 23 is slidably connected to and engaged with the internal teeth.

[0030] Specifically, when in the locked mode, the operating cross lever will cause the locking lever 17 to slide along the sleeve-shaped outer wall of the two rotating frames 20, causing the rotating columns 19 at both ends of the rotating frame 20 to rotate, which in turn causes the inner core 22 to drive the locking plate 23 to slide along the inner wall of the locking ring 21, and engage with the toothed shape of the inner wall of the locking ring 21 in real time, forming a real-time self-locking, and the locking lever 17 can rotate freely through the universal joint.

[0031] Reference Figure 6 Multiple locking blocks 9 are evenly fixedly connected to the outer wall of the push rod 6, multiple protrusions 10 are evenly fixedly connected to the outer wall of the rotating core 8, multiple sliding grooves 11 and slots 12 are evenly opened on the outer wall of the retaining ring 7, the push rod 6 is slidably connected to the inner wall of the retaining ring 7, the locking blocks 9 are slidably connected to the inner wall of the sliding groove 11, the protrusions 10 are slidably connected to the inner walls of the sliding groove 11 and slots 12, and multiple pointed blocks are evenly arranged on the outer wall of the push rod 6, with the outer walls of the protrusions 10 and the pointed blocks slidably connected.

[0032] Specifically, the locking block 9 is always slidably connected inside the slide groove 11 to prevent the top rod 6 from rotating, allowing the top rod 6 to only slide. When switching back to the real-time self-locking mode, pressing the adjusting rod 4 causes the adjusting rod 4 to press against the top rod 6. Then, the protrusion at the top of the top rod 6 will press against the protrusion 10 inside the slide groove 11, thereby driving the protrusion 10 to slide synchronously. The protrusion 10 slides along the slide groove 11. After the protrusion 10 slides out of the slide groove 11, it will continue to slide along the inclined outer wall of the retaining ring 7 into the retaining groove 12. Since the slide groove 11 is deeper and the retaining groove 12 is shallower, the sliding distance of the rotating core 8 is changed. The function rod 13 driven by the rear end of the rotating core 8 will push the insertion rod 15 a certain distance, thereby entering the slot of the locking rod 17, which can then drive the locking rod 17 to perform synchronous operation and locking.

[0033] Reference Figure 2The outer walls of multiple limiting plates 24 are all opened and penetrated by cross-shaped sliding grooves. The function rod 13 is slidably connected in one of the cross-shaped sliding grooves, the slider 14 is slidably connected in one of the cross-shaped sliding grooves, one end of the spring 16 is fixedly connected to the outer wall of the slider 14, and the other end of the spring 16 is fixedly connected to the outer wall of the function rod 13. Multiple compression springs are provided on the inner wall of one of the cross-shaped sliding grooves. One end of the compression spring is fixedly connected to the inner wall of the cross-shaped sliding groove, and the other end of the compression spring is fixedly connected to the outer wall of the function rod 13.

[0034] Specifically, the control lever is shown to move only along the cross direction without deviating, and the device is reset by spring 16.

[0035] Reference Figure 7 The outer wall of the locking rod 17 has a slot, the outer wall of the insertion rod 15 is slidably connected to the slot, the locking rod 17 is slidably connected to the inner wall of one of the limiting plates 24, and the outer wall of the locking rod 17 is slidably connected to the outer wall of the rotating frame 20.

[0036] Specifically, the insertion rod 15 is engaged by a slot, the engagement and disengagement are switched at any time by a sliding connection, and the rotation of the rotating frame 20 is driven by the sliding of the locking rod 17, thereby triggering the self-locking structure.

[0037] Working principle: When using the joystick, in the default state, the insertion rod 15 is inserted into the slot opened in the inner wall of the locking rod 17. At this time, the operating sleeve 2 will drive the internal connecting ring 3, which will then drive the adjusting rod 4, the function rod 13, and the insertion rod 15 from top to bottom, and then drive the locking rod 17 to move synchronously around the universal joint at the bottom of the locking rod 17. The cross grooves opened on the multiple cross limit plates 24 fixedly installed inside the outer shell 1 restrict the entire rod structure to cross movement. When the locking rod 17 is driven to operate in the cross direction, the locking rod 17 will slide along the outer wall of the rotating frame 20, driving the rotating frame 20 to rotate synchronously. Both ends of the rotating frame 20 are fixedly connected to the rotating column 19, and then the rotating frame 20 drives the rotating column 19 to drive the inner core 22 to rotate. The inner core 22 pushes the locking piece 23 to rotate through the slot. When the locking piece 23 rotates, its protrusion will slide along the toothed inner wall of the inner core 22 and engage in real time, and feed back to the locking rod 17, thereby forming the real-time locking of the joystick.

[0038] To handle complex operating situations, sometimes real-time locking of the control lever is not necessary; instead, more flexible operation is required. In such cases, the insertion rod 15 needs to disengage from the locking rod 17's slot, thus breaking their connection. This is achieved by placing the inner rod-shaped structure of the control sleeve 2 at the center of the cross control and pressing down on the adjusting rod 4. The adjusting rod 4 causes the fixedly connected top rod 6 to slide along the inner wall of the fixed sleeve 5. The top rod 6 then pushes the rotating core 8 to slide synchronously. At this time, the protrusion 10 connected to the outer wall of the rotating core 8 will slide along the slot 12 on the outer wall of the retaining ring 7, causing the function rod 13 to compress the spring 16. After the protrusion 10 slides out of the slot 12, it will continue to slide along the inclined outer wall of the rotating core 8 until it falls onto the outer wall of the slide groove 11. At this point, the adjusting rod 4 is released, and under the stress of the spring 16, all components are pushed back. The protrusion 10 engages with the inner wall of the slide groove 11, and during the retraction process, the functional rod 13 drives the bottom fixedly connected insertion rod 15 to retract together, causing the insertion rod 15 to disengage from the locking rod 17. At this point, operating the outer sleeve 2 to move the bottom rod-shaped structure in a cross shape will not trigger real-time locking, but will compress the spring connecting the outer wall of the functional rod 13 and the cross limit plate 24 for real-time rebound to meet the flexible operation requirements.

[0039] When real-time locking is required again, simply place the inner rod-shaped structure of the control sleeve 2 into the center of the cross control, press down the adjustment rod 4 again, and push the protrusion 10 out of the slide groove 11 through the locking block 9, so that it re-enters the locking groove 12 and engages. The function rod 13 drives the insertion rod 15 to slide down, allowing the insertion rod 15 to re-enter the locking rod 17 groove and form a connection with it, thus returning to the default real-time locking state.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
