For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figures 1 to 4As shown, the present invention provides a multi-directional mechanical rocker control device, the control device includes a housing 10, a control handle 40 installed on the housing 10, and four groups of trigger switch assemblies 20, the four groups of trigger switch assemblies 20 are evenly distributed in four directions around the control handle 40, and the four groups of trigger switch assemblies 20 are in a normally open position. The part of the housing 10 used to install the trigger switch assembly 20 is made of insulating material. Preferably, the housing 10 includes a mounting frame 11 and a shell 12 covered on the mounting frame 11, the shell 12 and the mounting frame 11 are assembled and connected, and an installation space and a movable space for the trigger switch assembly 20 and the control handle 40 are formed between the shell 12 and the mounting frame 11. Among them, the mounting frame 11 is made of insulating material.

[0030] The four groups of trigger switch assemblies 20 are respectively tensioned and connected to the mounting frame 11 through elastic mechanisms, so that the trigger switch assemblies 20 are automatically reset by the elastic preload force. In the initial state, the four groups of trigger switch assemblies 20 move toward the control handle 40 under the action of the elastic preload force, and the control handle 40 is centered and balanced. The control handle 40 is located at the center of the four groups of trigger switch assemblies 20. The control handle 40 can swing toward any group of trigger switch assemblies 20 under the drive of the operator, and the swing distance corresponds to the corresponding trigger signal. The four groups of trigger switch assemblies 20 are distributed in four directions. When the control handle 40 swings toward the corresponding trigger switch assembly 20, an independent signal in the corresponding direction is triggered to realize four-way rocker arm control, which is flexible to operate.

[0031] The control device further includes a push switch assembly 30 mounted on the housing 10, and the push switch assembly 30 is located in the axial moving direction of the control handle 40. The control handle 40 swings to trigger one of the trigger switch assemblies 20, or the control handle 40 presses to trigger the push switch assembly 30. The push switch assembly 30 is located in the axial moving direction of the control handle 40, and the control handle 40 can be extended and retracted along the axial direction, and can trigger the fifth independent signal during the sliding process of the control handle 40, thereby realizing independent control of five signals.

[0032] In this embodiment, the trigger switch assembly 20 and the push switch assembly 30 both adopt a mechanical trigger structure, and the overall signal is stable and highly reliable. The five-way signal control is concentrated in one control device, and the final push signal control is performed after the four-way direction adjustment is completed. The overall size is miniaturized, which can greatly reduce the installation space and improve the overall control performance. For example, on an aircraft operating panel or a remote control, the control handle 40 switches the adjustment direction by triggering the switch assembly 20, and presses the control handle 40 when the control adjustment is in place to trigger the push switch assembly 30, thereby controlling the corresponding device to achieve item delivery or corresponding function operation to achieve five-way signal control.

[0033] In one embodiment, the mounting frame 11 is provided with a cross-shaped intersecting mounting groove 111, each group of trigger switch assemblies 20 is distributed in the mounting groove 111, and the control handle 40 is located at the intersection center of the mounting groove 111. The mounting groove 111 is used to assemble each group of trigger switch assemblies 20, and also to separate each group of trigger switch assemblies 20, so as to avoid electrical interference between each other. Every two groups of trigger switch assemblies 20 are arranged opposite to each other and are located in the same straight line, so that the control handle 40 can swing back and forth in a straight line, and can push the two groups of trigger switch assemblies 20 to trigger correspondingly.

[0034] A control hole 115 is provided at the bottom of the mounting groove 111, the control handle 40 is slidably limited in the control hole 115, and the push switch assembly 30 is located at the bottom of the control hole 115. The control hole 115 is located at the bottom of the mounting groove 111, one end of the control handle 40 is located in the control hole 115 and can swing relative to the control hole 115, and at least part of the trigger switch assembly 20 is located within the swing range of the control handle 40, so as to achieve mechanical swing to push the contacts of the trigger switch assembly 20 to close and trigger the electrical signal.

[0035] A spring member 43 is installed in the control hole 115. The spring member 43 elastically pushes the control handle 40 to be limited to the control hole 115. The control handle 40 is spaced apart from the push switch assembly 30 under the elastic preload force of the spring member 43. The end of the control handle 40 is spaced apart from the push switch assembly 30, and the spring member 43 can be set as a compression spring. One end of the spring member 43 abuts against the bottom wall of the control hole 115; or, one end of the spring member 43 abuts against the housing 10 portion of the push switch assembly 30. When the operator presses the operating end of the control handle 40, the control handle 40 overcomes the elastic force of the spring member 43 and moves along the control hole 115 until the push switch assembly 30 is triggered. When the operator releases, the spring member 43 pushes the control handle 40 to move away from the push switch assembly 30, thereby realizing that the fifth signal stops outputting.

[0036] The spring member 43 is pushed against the end of the control handle 40 so that the control handle 40 has a reset capability and has a suitable rotation resistance, thereby improving the comfort of the rotation feel. Preferably, the control handle 40 includes a crank rod 42 and a rotating ball 44 protruding from the crank rod 42, the rotating ball 44 is limited to the control hole 115, and the outer diameter of the rotating ball 44 is greater than the opening size of the control hole 115. The rotating ball 44 is a spherical curved surface structure protruding from the side or end of the crank rod 42, and the rotating ball 44 is limited to the control hole 115 and can rotate in all directions. The spring member 43 abuts against the end face of the rotating ball 44, thereby realizing the abutment pressure, and the spherical surface of the rotating ball 44 rubs against the hole wall of the control hole 115 to form a rotation damping force. That is, the spring member 43 always abuts against the lowest point area of ​​the rotating ball 44. During the swinging process of the control handle 40, it can overcome the elastic preload force of the trigger switch assembly 20, so that the control handle 40 has a good push feeling and a good operating experience.

[0037] The rotating ball 44 can rotate around the axis of the control handle 40 without affecting the squeezing of the trigger switch assembly 20, and the installation is convenient and flexible. Further, a positioning rib is protruding from the end of the rotating ball 44, and the spring member 43 is sleeved on the positioning rib and abuts against the rotating ball 44. The spring member 43 bends as the control handle 40 swings, thereby maintaining the reset force of the automatic centering reset of the control handle 40. Further preferably, the spring member 43 is configured as a conical spring, that is, one end of the spring member 43 is a large end and the other end is a small end, the small end is sleeved on the positioning rib, and the large end is limited to the control hole 115, thereby further improving the centering reset ability of the control handle 40.

[0038] The outer diameter of the rotating ball 44 is larger than the opening size of the control hole 115. In an optional manner, the control hole 115 is in the shape of a stepped hole. The control handle 40 is inserted from the large hole end of the control hole 115 and passes through the small hole end, so that the rotating ball 44 abuts against the stepped portion. Preferably, the stepped portion is set as a spherical curved surface. The push switch assembly 30 is assembled to the opening of the large hole end and pushes the spring member 43 against the rotating ball 44. The pressing portion of the push switch assembly 30 is located in the extension direction of the control handle 40.

[0039] In another optional manner, a tubular protruding mounting ring 113 is provided at the bottom of the mounting groove 111, and the control hole 115 is the inner space of the mounting ring 113. An arc-shaped flange 114 is formed at the end of the mounting ring 113 toward the center of the control hole 115 to reduce the opening size of the control hole 115. The mounting ring 113 is a tubular structure, and the arc-shaped flange 114 is a curved surface convex structure to reduce the opening aperture of the opening of the mounting ring 113, and the inside of the mounting ring 113. Among them, the arc-shaped flange 114 forms a trumpet-shaped guide part at the opening of the control hole 115, which facilitates the control handle 40 to be squeezed into the control hole 115. After crossing the arc-shaped flange 114, the rotating ball 44 is limited to the arc-shaped flange 114 to avoid reversely pulling out of the control hole 115. Preferably, the control handle 40 is made of metal material or hard material, and the elastic preload force of the spring member 43 acting on the control handle 40 is less than the squeezing force of the control handle 40 to be squeezed into the mounting hole.

[0040] In a preferred embodiment, the mounting ring 113 is provided with at least one groove extending from the end toward the bottom of the mounting groove 111. The groove is cut along the axial direction of the mounting ring 113, wherein the cutting depth of the groove is greater than the width of the arc-shaped flange 114, thereby improving the elastic deformation effect at the opening of the mounting ring 113, facilitating the rotating ball 44 to be inserted into the mounting hole from the arc-shaped flange 114 and to be reversely restricted to the arc-shaped flange 114. Preferably, the width of the groove is less than 0.5 mm to reduce the impact on the structural strength of the mounting ring 113.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the crank rod 42 is in the shape of a rod and protrudes a rotating ball 44 to form a boss structure. The crank rod 42 at least partially contacts and pushes the trigger switch assembly 20. Accordingly, the partial protrusion of the crank rod 42 forms a pushing portion to correspondingly push the trigger switch assembly 20. In one embodiment, the control handle 40 includes a wear-resistant sleeve 45 rotatably sleeved on the crank rod 42, and the four groups of trigger switch assemblies 20 elastically push the wear-resistant sleeve 45. The wear-resistant sleeve 45 is an annular structure, and the wear-resistant sleeve 45 is made of wear-resistant material to improve the service life and stability of use. The wear-resistant sleeve 45 pushes the trigger switch assembly 20 as the control handle 40 swings to achieve the output of electrical signals in the corresponding direction. Among them, the wear-resistant sleeve 45 can rotate relative to the crank rod 42 to avoid the wear-resistant sleeve 45 always being in the same wear position, further improving the service life.

[0042] Preferably, the crank rod 42 is provided with a positioning groove 421, and the wear-resistant sleeve 45 includes a sleeve portion 452 and at least two limiting ribs 451 protruding from the inner wall of the sleeve portion 452, and the length of the limiting ribs 451 is less than the length of the sleeve portion 452. The sleeve portion 452 is sleeved on the crank rod 42, and the limiting ribs 451 are limited to the positioning groove 421. In addition, the minimum spacing size of the limiting ribs 451 is smaller than the opening size of the positioning groove 421, so that the wear-resistant sleeve 45 can rotate around the positioning groove 421 without being separated from the positioning groove 421, thereby achieving that the push position of the wear-resistant sleeve 45 and the trigger switch assembly 20 are always consistent, and the service life of the wear-resistant sleeve 45 can be improved through the rotation of the wear-resistant sleeve 45.

[0043] like Figure 2 , Figure 3 and Figure 6 As shown, each group of trigger switch assemblies 20 is arranged in the corresponding mounting groove 111 of the mounting frame 11, and the structures of the four groups of trigger switch assemblies 20 are the same. Among them, the trigger switch assembly 20 includes an inner conductive member 22, an outer conductive member 21, a connecting plate 25, a contact plate 23 connected to the connecting plate 25, and an elastic member 24 connected to the contact plate 23. The inner conductive member 22, the outer conductive member 21, the connecting plate 25 and the contact plate 23 are all made of metal conductive materials. The inner conductive member 22 and the outer conductive member 21 are fixed to the housing 10 at intervals to form a connection part for connecting the positive and negative power sources, wherein one end of the inner conductive member 22 and the outer conductive member 21 passes through the housing 10 to form a pin, and the other end is located in the housing 10 to form a contact part or a connection part.

[0044] One end of the elastic member 24 is connected to the housing 10, specifically, one end of the elastic member 24 is hooked and connected to the mounting frame 11. The mounting frame 11 is provided with a connecting shaft 27 spanning the mounting slot 111, the elastic member 24 is connected to the connecting shaft 27, and the other end of the elastic member 24 is connected to the contact plate 23. The other end of the contact plate 23 is driven away from the external conductive member 21 by the elastic preload force of the elastic member 24, and the connecting plate 25 is against the control handle 40.

[0045] Preferably, the elastic member 24 adopts a tension spring, which is stretched to form a contraction elastic preload, and the tension spring drives the contact plate 23 to move toward the opening direction of the mounting groove 111. The two ends of the connecting plate 25 are bent in opposite directions, and the two ends form structures similar to hooks. One end of the connecting plate 25 is movably hooked to the inner conductive member 22, and the other end is movably hooked to the contact plate 23. Under the action of the elastic preload of the elastic member 24, one end of the contact plate 23 is movably abutted against the upper hook of the connecting plate 25, so that the contact plate 23 and the connecting plate 25 cooperate with the elastic member 24 to form a movable joint structure. The connecting plate 25 can rotate around the lower hook 251 under the drive of the control handle 40, and the connecting plate 25 pushes the contact plate 23 to rotate and abut against the outer conductive member 21 to form a path triggering electrical signal.

[0046] Furthermore, the mounting groove 111 is provided with a stop positioning rib 112, and the contact plate 23 swings in the mounting groove 111 and abuts against the stop positioning rib 112 under the elastic preload force of the elastic member 24. The stop positioning rib 112 protrudes toward the mounting groove 111, and the two relative stop positioning ribs 112 are used to limit the maximum expansion angle of the contact plate 23. Among them, the stop positioning rib 112 forms a step structure in the mounting groove 111, the maximum width of the contact plate 23 is greater than the width between the two stop positioning ribs 112, and the width of the part of the contact plate 23 that cooperates with the connecting plate 25 is less than the width between the two stop positioning ribs 112, so that the end of the contact plate 23 can be inserted between the two stop positioning ribs 112. Therefore, the control handle 40 pushes the connecting plate 25 to move into the sliding groove, and then the contact plate 23 rotates to trigger the external conductive member 21. The contact plate 23 keeps the control handle 40 under the pull of the spring member 43 and is subjected to an elastic preload force for centering reset. When the operator releases the control handle 40, the contact plate 23 pushes the control handle 40 to reset and abuts against the stop positioning rib 112 under the action of the elastic preload force, and the reset consistency is high.

[0047] Further preferably, the contact plate 23 is provided with a contact member 26, the contact member 26 faces the external conductive member 21, and the surface of the contact member 26 is coated with a gold coating. The contact member 26 is located at the free end of the contact plate 23, and the spring member 43 is connected to the free end so that the contact member 26 is away from the external conductive member 21 in the initial state. The contact member 26 is provided with a gold coating to improve wear resistance and conductive contact sensitivity.

[0048] The mounting frame 11 is cylindrical, and the mounting groove 111 is axially recessed from the top. The mounting groove 111 is a cross-shaped structure, and the mounting groove 111 extends to the outer peripheral wall of the mounting frame 11. The trigger switch assembly 20 is inserted into the mounting groove 111 from the opening of the mounting groove 111, and is assembled accordingly. Further, the housing 10 also includes a shell 12 that is covered on the mounting frame 11, and a cross-shaped limiting groove is provided on the top of the shell 12, and the shell 12 and the mounting frame 11 are snap-fitted and fixed. The shell 12 is covered on the mounting frame 11 from the open end of the mounting frame 11 to enclose the trigger switch assembly 20 in the shell 12. The shell 12 and the mounting frame 11 are fixed as a whole, thereby forming a connection structure, which can not only maintain the stability of the internal electrical space, but also provide protection performance and convenient installation. Preferably, the outer peripheral wall of the housing 10 is provided with a positioning flange 121 to facilitate the definition of the installation position.

[0049] Preferably, the end of the control handle 40 passes through the limit groove, and the cross-shaped limit groove can guide and limit the movable direction and range of the control handle 40, and the activity reliability is high. Preferably, the overall structural size of the control device is small to form a small-sized, highly integrated multifunctional control element. Preferably, the outer diameter of the housing 10 is set to D, where 16mm≤D≤45 mm. For example, the outer diameter D of the housing 10 inserted into the installation portion is 16mm, 18mm, 20mm, 22mm, 24mm, 30mm, 36mm, 40mm, 45mm.

[0050] Furthermore, a handle cap 41 is installed at the end of the control handle 40, and the handle cap 41 is provided with an anti-skid mechanism to improve the anti-skid effect. For example, the anti-skid mechanism is provided as a concave groove or a convex ring groove. Alternatively, the anti-skid mechanism is provided as a plurality of tooth-shaped groove structures. The outer diameter of the outer contour of the handle cap 41 is greater than or equal to the outer diameter of the housing to realize a protective structure.
