[0051] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] Reference Figures 1-10 : A modular 3D joystick for easy replacement of LED modules, including a frame, a joystick device, an LED device and a fixing device; the joystick device is fixedly installed on the frame; there are multiple LED devices, the LED device includes a first mounting frame, the first mounting frame is slidably installed on the frame, and multiple LED lamps are fixedly installed on the first mounting frame; there are multiple fixing devices and they correspond one to one with the LED devices, the fixing device includes a pressure rod and a clamping assembly, the pressure rod is slidably installed on the frame, the clamping assembly is fixedly installed on the frame, and the driving end of the clamping assembly is transmission connected to the pressure rod.

[0053] The present application achieves the function of improving the interactivity of the 3D joystick while quickly disassembling and assembling the LED module through a frame, a joystick device, an LED device and a fixing device, thereby facilitating the maintenance of the LED module and solving the defect of the traditional 3D joystick that once the LED module is damaged, the entire 3D joystick needs to be removed to replace the LED module; the joystick device and the LED lamp are electrically connected to the controller; the operator remotely controls the joystick device, and at the same time, the LED lamp provides feedback to the operator's control actions, thereby improving the operator's experience. However, the LED lamp may experience brightness reduction or damage during long-term use, and is a consumable part in the 3D joystick. To this end, the LED device and the fixing device are designed. The split design of the frame and the first mounting bracket allows the operator to maintain the LED lamp without having to disassemble the 3D joystick as a whole. The LED lamp can be quickly disassembled and assembled by driving the fixing device. When the LED lamp needs to be removed, the pressing assembly first drives the pressure rod to slide, releases the pressure rod from fixing the first mounting bracket, and then removes the first mounting bracket. Then, the LED lamp on the first mounting bracket is repaired or replaced.

[0054] Reference Figure 2 、 Figure 3 、 Figure 6 and Figure 10 : The clamping assembly includes a rack, a nut and a rotating gear; the rack is fixedly mounted on the first mounting frame; the nut is rotatably mounted on the frame, and the nut is threadedly connected to the pressure rod; the rotating gear is fixedly sleeved on the nut, and the rotating gear is transmission-connected to the rack.

[0055] The present application uses a rack, a nut, and a rotating gear to automatically press the first mounting bracket as the first mounting bracket slides, thereby further improving the portability of the LED device. When removing the LED lamp, the operator first pulls out the first mounting bracket. As the first mounting bracket slides, the rack is driven to slide. As the rack slides, the rotating gear connected to the rack is driven to rotate. The rotating gear drives the nut to rotate, and the nut drives the pressure rod threadedly connected to the rack to move upward, thereby releasing the pressure rod from fixing the first mounting bracket. After the repair and replacement is completed, the operator inserts the first mounting bracket into the rack. As the first mounting bracket slides, the rack is driven to move. The rack drives the rotating gear and nut to rotate. As the first mounting bracket moves, the pressure rod presses the first mounting bracket tighter, fixing the first mounting bracket.

[0056] Reference Figure 1-Figure 5 : It also includes a covering mechanism, which includes a second mounting frame and a sliding cover; the second mounting frame is fixedly installed on the frame; the sliding cover is slidably installed on the second mounting frame.

[0057] The present application achieves the function of preventing the first mounting bracket from loosening by external force during use through the second mounting bracket and the sliding cover, thereby achieving the effect of further fixing the LED device; when the operator removes the LED lamp, he first slides the sliding cover and then pulls out the first mounting bracket. As the first mounting bracket slides, the rack is driven to slide, and as the rack slides, the rotating gear and the nut are driven to rotate, and the nut drives the pressure rod threadedly connected thereto to move upward, thereby releasing the pressure rod from fixing the first mounting bracket; after the maintenance and replacement is completed, the operator inserts the first mounting bracket into the rack again, and as the first mounting bracket slides, the rack is driven to move, and the rotating gear and the nut are driven to rotate through the rack. As the first mounting bracket moves, the pressure rod presses the first mounting bracket tighter, and then slides the sliding cover to restrict the first mounting bracket through the sliding cover to prevent the first mounting bracket from sliding out by itself.

[0058] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 : The capping mechanism also includes a reset component, which includes a limit block and an elastic member; the limit block is fixedly mounted on the frame; and both ends of the elastic member are fixedly connected to the second mounting frame and the limit block respectively.

[0059] The present application realizes the function of automatic resetting of the second mounting bracket through a limit block and an elastic member, thereby preventing the operator from forgetting to close the sliding cover; the elastic member is preferably a compression spring; when disassembling the LED lamp, the operator first overcomes the elastic force of the elastic member to drive the sliding cover down, causing the elastic member to compress, and then pulls out the first mounting bracket to complete the disassembly of the LED lamp; after the maintenance is completed, the sliding cover is driven down again, and then the first mounting bracket is inserted. When the insertion is completed, the sliding cover loses the cover of the first mounting bracket, and is driven to automatically move up under the elastic force of the elastic member, limiting the sliding of the first mounting bracket, thereby preventing the operator from forgetting to close the sliding cover, resulting in unstable installation of the first mounting bracket.

[0060] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 and Figure 9 : The fixing device also includes a positioning assembly, which includes a rotating shaft and a positioning block; the rotating shaft is rotatably mounted on the frame through a torsion spring; the positioning block is fixedly sleeved on the rotating shaft.

[0061] When the insertion is completed, the positioning block automatically rotates under the elastic force of the torsion spring, and the sliding cover loses the cover of the positioning block. Under the elastic force of the elastic member, the sliding cover is driven to move up automatically, thereby limiting the sliding of the first mounting frame.

[0062] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 : The frame includes a box body and a cover body; the rocker device is fixedly installed in the box body, and the positioning assembly is installed on the box body; the cover body is fixedly connected to the box body by bolts, and a slide rail for installing the first mounting bracket is opened on the cover body, the pressure rod is slidably installed on the cover body, and the clamping assembly is installed on the cover body.

[0063] The present application realizes the function of stably supporting the first mounting frame through the box body and the cover body, thereby achieving the effect of separating the assembly and disassembly of the rocker device and the LED device; when disassembling and assembling the LED device, the operator only needs to disassemble and assemble the first mounting frame through the fixing device and the covering device; and when disassembling and assembling the rocker device, the operator separates the box body and the cover body by removing the bolts, and then disassembles and assembles the rocker device.

[0064] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 8 : The rocker device includes a main shaft, a handle, an arch bracket and a variable resistor; the main shaft is hingedly installed in the box body; the handle is fixedly sleeved on the main shaft; there are two arch brackets, which are rotatably installed in the box body, and the two arch brackets slide with the main shaft; there are two variable resistors, which slide with the two arch brackets respectively.

[0065] The present application realizes the function of converting the swing of the handle into an electrical signal through the main shaft, handle, arch bracket and variable resistor; the operator drives the main shaft to tilt in a specific direction by swinging the handle, and the main shaft drives the two arch brackets to rotate. The rotation of the two arch brackets causes the resistance value of the variable resistor to change, thereby feeding back the rotation data of the main shaft to the controller.

[0066] Reference Figure 10 : A steel ball is rotatably installed at the bottom of the pressure rod.

[0067] The present application achieves the function of reducing the friction between the pressure rod and the first mounting frame through the steel ball; during the insertion process of the first mounting frame, the pressure of the pressure rod on the first mounting frame will gradually increase, resulting in a gradual increase in the friction between the pressure rod and the first mounting frame, which in turn causes the pressure rod and the first mounting frame to wear too quickly. For this purpose, a steel ball is rotatably installed at the bottom of the pressure rod; the sliding friction between the pressure rod and the first mounting frame is converted into rolling friction through the transition of the steel ball, which greatly reduces the wear rate between the pressure rod and the first mounting frame, thereby increasing the service life of the parts.

[0068] Reference Figure 2 、 Figure 3 、 Figure 6 、 Figure 8 and Figure 9 : An embedded handle is fixedly installed on the first mounting frame.

[0069] The present application achieves the function of improving the operator's operational portability through the embedded handle; when the operator disassembles and installs the LED lamp, the operator slides the first mounting bracket through the embedded handle to prevent the operator from slipping when sliding the first mounting bracket, and the embedded handle can prevent the first mounting bracket from obstructing the installation and sliding of the handle.

[0070] Reference Figure 2 、 Figure 4 and Figure 5 : A fixed handle is fixedly installed on the sliding cover.

[0071] The present application realizes the function of facilitating the operator to slide the sliding cover by means of a fixed handle, thereby further improving the operator's portability of operation; during the process of disassembling and assembling the LED, the operator slides the sliding cover by means of the fixed handle. Since most 3D joysticks are small in size, it is difficult for the operator to find the force point when sliding the sliding cover. For this purpose, a fixed handle is provided, and the operator can slide the sliding cover very conveniently by means of the fixed handle.

[0072] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
