Description

Technical Field

[0001] This application relates to the field of joystick technology, and more particularly to a control joystick, and also to a flight simulator. Background Technology

[0002] In related technologies, the control joystick uses the rotation of the joystick to assist in changing the working state of the controlled object. How to make the joystick return to its original position is an issue that needs to be addressed. Utility Model Content

[0003] Therefore, it is necessary to propose a control joystick capable of returning to its original position after rotation. A flight simulator is also proposed.

[0004] According to a first aspect of this application, a control rocker includes: a housing; and a connecting portion rotatably connected to the housing. The connecting portion includes a rocker shaft and a bushing, the bushing being fixedly connected to the rocker shaft. The bushing is provided with a rotational reset structure, which is used to reset the connecting portion relative to the housing. By providing the rotational reset structure on the bushing, when an external force is applied to rotate the housing relative to the connecting portion by a certain angle and then the housing is released, the rotational reset structure allows the housing to rotate back to its initial position in the opposite direction, thereby ensuring that the housing is in its initial position during the next rotation operation, thus guaranteeing the accuracy of the next operation.

[0005] In some embodiments, the control rocker arm further includes a housing, which is fitted onto the connecting portion and fixedly connected to the housing. The inner wall of the housing is fitted onto the rocker arm shaft. The outer wall of the housing is fixedly connected to the housing. The shape of the outer wall of the housing can well match the inner wall of the housing, thereby facilitating relative rotation between the housing and the rocker arm shaft, and simplifying the design of the rocker arm shaft.

[0006] In some embodiments, the rotational reset structure includes a limiting groove and an elastic element disposed in the bushing, and the housing has a limiting portion located in the limiting groove and abutting against the elastic element in the circumferential direction. When no external force is applied to rotate the housing relative to the connecting part, the housing is in a predetermined initial position relative to the connecting part. When an external force is applied to rotate the housing relative to the connecting part by a certain angle and then the external force is withdrawn, the rotational reset structure can cause the housing to rotate back to its original position in the opposite direction, thereby ensuring that the housing is in the initial position during the next rotation operation, and thus ensuring the accuracy of the next operation.

[0007] In some embodiments, the rotational reset structure further includes a fixing portion disposed on the bushing, and the elastic element includes a first lever arm and a second lever arm, which together clamp the limiting portion and the fixing portion. By giving the elastic element two lever arms, on the one hand, energy storage of the elastic element is achieved by increasing the opening angle of the two lever arms; on the other hand, the two lever arms are located on both sides of the limiting portion and the fixing portion, respectively, which facilitates circumferential contact between the second lever arm and the limiting portion.

[0008] In some embodiments, along the radial direction of the bushing, a first radial segment and a second radial segment are respectively provided on both sides of the limiting portion. In the rotation direction of the housing, the length of the first radial segment is greater than the length of the second radial segment. The first radial segment abuts against the first lever arm and the second lever arm. During the rotation of the housing, only the first radial segment maintains point contact with the first lever arm or the second lever arm, so that the first lever arm or the second lever arm is subjected to uniform force and the degree of opening changes uniformly, which can achieve a better operating feel.

[0009] In some embodiments, an angle sensor assembly is provided on the top of the bushing, and an angle sensing assembly is provided inside the housing. The angle sensing assembly and the angle sensor assembly together form an angle detection module capable of detecting the rotation angle of the housing, thereby enabling the control joystick to detect and output the rotation angle of the housing.

[0010] In some embodiments, a connecting seat is further included, which is detachably connected to the bushing, and / or the angle sensor assembly is detachably disposed on the connecting seat. This allows for the detachable assembly of the angle sensor assembly and the bushing, facilitating the installation of the angle sensor assembly. In some embodiments, the bushing has an axial connecting hole, the rocker shaft is connected to the bushing via a first axial connector fixedly connected to the connecting hole, and the connecting seat is connected to the bushing via a second axial connector fixedly connected to the connecting hole. The first and second axial connectors share the connecting hole on the bushing, achieving the connection between the connecting seat and the bushing, and the connection between the rocker shaft and the bushing, simplifying the bushing structure and providing a simple and reliable connection method.

[0011] In some embodiments, the bushing is fitted onto the rocker shaft in a manner that prevents relative rotation, and the bushing and the rocker shaft are also fixedly connected by a radial connector. By fitting the bushing and the rocker shaft in a manner that prevents relative rotation, and by fixing them axially through a first axial connector and radially through a radial connector, both circumferential fixing of the rocker shaft and the bushing are achieved, as well as axial and radial connection between the rocker shaft and the bushing.

[0012] In some embodiments, a connecting nut is further included, which is axially movably connected to the rocker shaft for connecting to the base shaft. The connecting nut enables detachable installation of the rocker shaft and the base shaft, thereby facilitating the assembly of the control unit for the flight simulator.

[0013] In some embodiments, the connecting nut includes a communicating hole and a threaded hole; the rocker shaft has an extension portion, which passes through the communicating hole and extends into the threaded hole, with the outer diameter of the extension portion being larger than the inner diameter of the communicating hole. The connecting nut is movably connected to the rocker shaft, so that when the connecting nut is connected to the base shaft, the base shaft can be tightened against the extension portion simply by rotating the connecting nut, thereby completing the connection between the rocker shaft and the base shaft.

[0014] In some embodiments, the housing has a receiving cavity, and the rocker shaft is connected to the housing via at least two rotating connectors. By providing at least two rotating connectors, the stability of the housing during relative rotation with the rocker shaft can be increased. In some embodiments, the rocker shaft has a mounting step, and a retaining spring is provided between the mounting step and the rotating connector. The side of the retaining spring connected to the rocker shaft has a beveled portion, and the mounting step has a matching beveled area. By providing the retaining spring to apply axial force to the rotating connector and restrict movement, the rotating connector is prevented from disengaging, thus achieving translational degrees of freedom other than rotational degrees of freedom. The retaining spring can also absorb axial installation tolerances of the rotating connector. Furthermore, the beveled area ensures that the retaining spring and the mounting step always abut against each other, thereby preventing circumferential movement.

[0015] In some embodiments, a locking structure is also included, configured to selectively connect the housing and the rocker shaft to restrict or release relative rotation between the housing and the rocker shaft.

[0016] In some embodiments, the locking structure includes a connecting rod fixedly connected to the housing, and the rocker shaft has a positioning groove that mates with the connecting rod. By providing a locking structure, the rotation of the housing is locked when the control rocker is not needed, thus preventing accidental operation.

[0017] According to a second aspect of this application, a flight simulator includes the aforementioned control joystick.

[0018] In the flight simulator of this application, a rotation reset structure is provided on the bushing. When an external force is applied to rotate the housing relative to the connecting part by a certain angle and then the housing is released, the rotation reset structure can make the housing rotate back to its original position in the opposite direction, thereby ensuring that the housing is in the initial position during the next rotation operation, and thus ensuring the accuracy of the next operation.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] The first aspect of this application proposes a control joystick that can be used in situations where rotation is required to assist in changing the state of a controlled object. For example, the control joystick can be used to form flight simulators or game controllers.

[0034] refer to Figure 1 and Figure 2 As shown, a control rocker arm 100 according to some embodiments of this application includes a housing 20 and a connecting portion 10. The connecting portion 10 is rotatably connected to the housing 20. The connecting portion 10 includes a rocker arm shaft 110 and a bushing 160. The bushing 160 is fixedly connected to the rocker arm shaft 110, and the bushing 160 is provided with a rotation reset structure 161, which is used to reset the connecting portion 10 relative to the housing 20.

[0035] The housing 20 has a receiving cavity 201 for accommodating the connecting part 10. Specifically, the housing 20 may consist of two half-shells that interlock. Various control buttons 202 may be further provided on the housing 20.

[0036] Specifically, refer to Figure 1 and Figure 2 The housing 20 includes two opposing half-shells 203, which are arranged opposite each other and their end edges contact and enclose each other to form a receiving cavity 201, which accommodates the connecting part. Figure 1 In the middle, two half-shells 203 are arranged on the left and right, with their end edges attached together to form a receiving cavity 201. The two half-shells 203 can be symmetrical or different.

[0037] The top of the connecting portion 10 extends into the receiving cavity 201 of the housing 20, while the bottom of the connecting portion 10 is located outside the housing 20. For example... Figure 3 , Figure 6 and Figure 7 As shown, the bottom of the connecting part 10 is used to connect to the base shaft 50 in the flight simulator, thereby forming the control device of the flight simulator. Specifically, the joystick shaft 110 is rotatably connected to the housing 20. One side of the joystick shaft 110 is used to connect to the base shaft 50. The bushing 160 is provided on the top of the joystick shaft 110. After the connecting part 10 is connected to the base shaft 50, the housing 20 can rotate relative to the connecting part 10.

[0038] refer to Figure 2 For example, the control joystick 100 also includes a housing 30. The housing 30 is fitted onto the connecting portion 10 and fixedly connected to the housing 20. Specifically, the inner wall of the housing 30 is fitted onto the joystick shaft 110. The outer wall of the housing 30 is fixedly connected to the housing 20. The shape of the outer wall of the housing 30 can be well matched with the inner wall of the housing 20, so that the housing 30 can rotate relative to the joystick shaft 110, which facilitates the relative rotation between the housing 20 and the joystick shaft 110, and simplifies the external design of the joystick shaft 110.

[0039] The control rocker arm 100 of this application is provided with a rotation reset structure 161 on the bushing 160. The rotation reset structure 161 includes, but is not limited to, a damper, an elastic structure, etc. When no external force is applied to rotate the housing 20 relative to the connecting part, the housing 20 is in a predetermined initial position relative to the connecting part 10. When an external force is applied to rotate the housing 20 relative to the connecting part 10 by a certain angle and then the external force is withdrawn (i.e., the housing 20 is released), the rotation reset structure 161 can cause the housing 20 to rotate back in the opposite direction (i.e., return to the relative position of the connecting part and the housing when no external force is applied), thereby ensuring that the housing 20 is in the initial position during the next rotation operation, and thus ensuring the accuracy of the next operation.

[0040] refer to Figures 4 to 6 , Figure 9 In some embodiments, the rotational reset structure 161 includes a limiting groove 1612 and an elastic member 1613 disposed on the bushing 160. The housing 30 is provided with a limiting portion 310 located in the limiting groove 1612 and abutting against the elastic member 1613 in the circumferential direction.

[0041] A limiting groove 1612 is specifically provided on the outer circumferential surface of the bushing 160. An elastic member 1613 is connected to the bushing 160. Exemplarily, the limiting groove 1612 is a U-shaped groove recessed radially inward along the bushing 160. A limiting portion 310 of the sleeve 30 extends axially along the bushing 160 and into the limiting groove 1612. The limiting portion 310 and the elastic member 1613 abut against each other in the circumferential direction of the bushing 160. Specifically, the specific structure of the elastic member 1613 is not limited; it is simply configured to be fixed to the bushing 160, and at least a portion of the elastic member 1613 is located on the rotation path of the limiting portion 310.

[0042] Thus, when the housing 20 rotates relative to the rocker shaft 110, the housing 20 drives the sleeve 30 to rotate, and the limiting part 310 deforms the elastic element 1613 in the circumferential direction and stores energy. When the external force acting on the housing 20 is removed, the elastic element 1613 causes the housing 20 to return to its initial position through its elastic force. Furthermore, the rotation reset structure 161 also includes a fixing part 1611 provided on the bushing 160. The elastic element 1613 includes a first lever arm 1614 and a second lever arm 1615, which together clamp the limiting part 310 and the fixing part 1611.

[0043] refer to Figure 5 As shown, the limiting part 310 and the fixing part 1611 are arranged sequentially in the radial direction of the bushing 160. The first force arm 1614 and the second force arm 1615 of the elastic member 1613 simultaneously clamp the limiting part 310 and the fixing part 1611. The two sides of the limiting part 310 abut against the first force arm 1614 and the second force arm 1615 respectively. When the housing 20 rotates counterclockwise relative to the rocker shaft 110, the limiting part 310 pushes the second force arm 1615 to move and gradually open relative to the first force arm 1614, causing the elastic member 1613 to store energy. Immediately after the housing 20 is released, the elastic member 1613 releases energy, causing the housing 20 to return to its initial position. Correspondingly, when the housing 20 rotates clockwise relative to the rocker shaft 110, the limiting part 310 pushes the first force arm 1614 to move and gradually open relative to the second force arm 1615, causing the elastic member 1613 to store energy. When the housing 20 is released immediately, the elastic element 1613 releases energy, causing the housing 20 to return to its initial position.

[0044] In this embodiment, the elastic member 1613 has two lever arms. On the one hand, the elastic member 1613 can store energy by increasing the opening angle of the two lever arms. On the other hand, the two lever arms are located on both sides of the limiting part 310 and the fixing part 1611, which facilitates the first lever arm 1614 and the second lever arm 1615 to circumferentially abut against the limiting part 310.

[0045] Further, refer to Figure 5 Along the radial direction of the bushing 160, the limiting part 310 has a first radial segment 311 and a second radial segment 312 on both sides. Furthermore, in the rotational direction of the housing 20, the length of the first radial segment 311 is greater than the length of the second radial segment 312.

[0046] Through the above design, the cross-section of the limiting part 310 is trapezoidal or trapezoidal, with the longer side of the trapezoid closer to the center of the bushing 160. Thus, when the housing 20 is in its initial position relative to the connecting part 10, both ends of the first radial segment 311 abut against the first lever arm 1614 and the second lever arm 1615, respectively. Furthermore, during the counterclockwise rotation of the housing 20 relative to the connecting part 10, only the first radial segment 311 maintains point contact with the second lever arm 1615. During the clockwise rotation of the housing 20 relative to the connecting part 10, only the first radial segment 311 maintains point contact with the first lever arm 1614. This ensures that during the rotation of the housing 20, only the first radial segment 311 maintains point contact with either the first lever arm 1614 or the second lever arm 1615, resulting in uniform force distribution and a uniform change in the degree of opening, thus achieving a better operational feel.

[0047] For example, refer to Figure 2 , Figure 5 and Figure 6 The bushing 160 has a positioning space 1601. The elastic element 1613 is a torsion spring. The torsion spring includes a body, a first lever arm 1614 and a second lever arm 1615, which are the two torsion arms of the torsion spring. The body of the torsion spring is positioned in the positioning space 1601.

[0048] In a specific configuration, the bushing 160 is also provided with a positioning post 1602. The positioning post 1602 and the fixing part 1611 are spaced apart in the circumferential direction of the bushing 160, forming the aforementioned positioning space 1601. The body of the torsion spring is engaged between the positioning post 1602 and the fixing part 1611. The first lever arm 1614 and the second lever arm 1615 extend outward along the radial direction of the bushing 160, and the first lever arm 1614 and the second lever arm 1615 respectively abut against the limiting part 310.

[0049] When the housing 20 rotates in the opposite direction to the rocker arm 110, the first lever arm 1614 and the second lever arm 1615 are twisted by the pressure of the limiting part 310, which increases the restoring torque of the torsion spring. When the housing 20 is released, the torsion spring drives the sleeve 30 back to its original position, realizing the return function.

[0050] In this application, the housing 20 can reciprocate within an 18° range relative to the rocker arm 110. For example, the central angle of the limiting groove 1612 is 36°, and the limiting part 310 is centrally located within the limiting groove 1612. The limiting part 310 and the second lever arm 1615 are constrained in their rotation range by the limiting groove 1612. Thus, the housing 20 can reciprocate within an 18° range relative to the rocker arm 110.

[0051] refer to Figure 2 , Figure 6 In some embodiments, the top of the bushing 160 is provided with an angle sensor assembly 120, and the housing 20 is provided with an angle sensing assembly 210.

[0052] The angle sensor assembly 120 can be fixedly or detachably mounted on the top of the bushing 160, while the angle sensing assembly 210 can be fixedly or detachably mounted on the inner wall of the housing 20. Exemplarily, the angle sensor assembly 120 is a magnetic component, such as a magnet or a magnetic stone. The angle sensing assembly 210 is a Hall effect circuit board. In other embodiments, the configuration can be exactly the opposite. The Hall effect circuit board obtains information about the relative angle change between the housing 20 and the rocker shaft 110 by sensing changes in magnetic field strength.

[0053] The angle sensing component 210 and the angle sensor component 120 together form an angle detection module that can detect the rotation angle of the housing 20, thereby enabling the control joystick 100 to detect and output the rotation angle of the housing 20.

[0054] refer to Figure 3 , Figure 6 In some embodiments, the control joystick 100 also includes a connector 180. The connector 180 is detachably connected to the bushing 160; and / or, the angle sensor assembly 120 is detachably disposed on the connector 180.

[0055] In this application, the connecting seat 180 may be detachably connected to the bushing 160, while the angle sensor assembly 120 may be detachably connected to the connecting seat 180. Alternatively, the connecting seat 180 and the bushing 160 may be integrated and non-detachable, while the angle sensor assembly 120 may be detachably connected to the connecting seat 180. Another option is that the connecting seat 180 may be detachably connected to the bushing 160, but the angle sensor assembly 120 cannot be easily disassembled.

[0056] The angle sensor assembly 120 and the bushing 160 can be detachably assembled in the above manner, which facilitates the installation of the angle sensor assembly 120.

[0057] For example, the connector 180 has a connector groove 181, and the angle sensor assembly 120 is embedded and fixed in the connector groove 181. In this way, the angle sensor assembly 120 is detachably fixed to the connector 180.

[0058] In some embodiments, the connecting seat 180 is connected to the bushing 160 in the following manner. (See reference...) Figure 3 , Figure 6 The bushing 160 has an axial connecting hole 162. The rocker shaft 110 is connected to the bushing 160 via a first axial connector 171 that is fixedly connected to the connecting hole 162, and the connecting seat 180 is connected to the bushing 160 via a second axial connector 173 that is fixedly connected to the connecting hole 162.

[0059] For example, the connecting hole 162 has internal threads. Both the first axial connector 171 and the second axial connector 173 are screws; the first axial connector 171 extends upwards and connects to the connecting hole 162, and the second axial connector 173 extends downwards and connects to the connecting hole 162. The connecting hole 162 can also be a smooth hole, and the first axial connector 171 and the second axial connector 173 can be screws or fixed screws.

[0060] Specifically, the rocker shaft 110 has a hollow cavity 114 extending through one side. One side of the rocker shaft 110 abuts against the end of the connecting hole 162. One end of the first axial connector 171 abuts against the top of the hollow cavity 114, and the other end passes through the top of the hollow cavity 114 and connects to the connecting hole 162. The hollow cavity 114 facilitates the connection of the first axial connector 171 to the connecting hole 162, while also reducing the weight of the rocker shaft 110, thereby lowering costs.

[0061] In this embodiment, the first axial connector 171 and the second axial connector 173 share the connecting hole 162 on the bushing 160, which realizes the connection between the connecting seat 180 and the bushing 160, and the connection between the rocker shaft 110 and the bushing 160, simplifying the structure of the bushing 160 and making the connection simple and reliable.

[0062] refer to Figure 3 , Figures 6 to 9 In order to improve the reliability of the connection between the bushing 160 and the rocker shaft 110, in some embodiments, the bushing 160 and the rocker shaft 110 are fitted together in a manner that prevents relative rotation, and the bushing 160 and the rocker shaft 110 are also fixedly connected by a radial connector 172.

[0063] Specifically, the bushing 160 includes a first cylindrical portion 163 and a second cylindrical portion 165 connected axially. The first cylindrical portion 163 is sleeved on the rocker shaft 110. The inner wall of the first cylindrical portion 163 has a first flat area 164. The outer wall of the rocker shaft 110 has a first flat part 115. The first flat part 115 is in contact with the first flat area 164. Both the first flat part 115 and the first flat area 164 are planar areas. After they are in contact, the bushing 160 and the rocker shaft 110 can only slide relative to each other axially but cannot rotate relative to each other.

[0064] The radial connector 172 radially connects the bushing 160 to the rocker shaft 110. The radial connector 172 passes sequentially through the bushing 160 and the rocker shaft 110, and is fixedly connected to the rocker shaft 110. Specifically, the radial connector 172 can be a screw, and the rocker shaft 110 has a matching threaded hole 152.

[0065] In this embodiment, the rocker arm shaft 110 is fitted with the bushing 160 in a manner that prevents relative rotation, and the two are fixed in the axial direction by the first axial connector 171 and fixed in the radial direction by the radial connector 172. Thus, the rocker arm shaft 110 and the bushing 160 are fixed in the circumferential direction (which is also the rotation direction of the housing 20), and the rocker arm shaft 110 and the bushing 160 are connected in the axial and radial directions.

[0066] In some embodiments, reference is made to Figure 6 , Figure 9 and Figure 10 The connecting seat 180 and the bushing 160 are fitted together in a manner that prevents relative rotation. For example, the outer wall of the second cylindrical portion 165 has a second flat area 166. The connecting seat 180 has a matching second flat part 182. The second flat part 182 and the second flat area 166 are in contact. Both the second flat part 182 and the second flat area 166 are planar; after they are in contact, the connecting seat 180 and the bushing 160 can only slide relative to each other axially but cannot rotate relative to each other. When the second axial connector 173 connects the connecting seat 180 and the bushing 160, the connecting seat 180 and the bushing 160 are also axially fixedly connected.

[0067] refer to Figure 3 , Figure 6 and Figure 7 The control joystick 100 of this application has a joystick axis 110 for connecting to the base axis 50 of the flight simulator.

[0068] To facilitate the connection between the rocker arm shaft 110 and the base shaft 50, the control rocker arm 100 also includes a connecting nut 150 axially movably connected to the rocker arm shaft 110. The connecting nut 150 is used to connect to the base shaft 50. Specifically, the connecting nut 150 includes a communicating hole 151 and a threaded hole 152. The rocker arm shaft 110 has an extension 112, which passes through the communicating hole 151, and the extension 112 extends into the threaded hole 152. The outer diameter of the extension 112 is larger than the inner diameter of the communicating hole 151. The threaded hole 152 is also used for threaded connection with the base shaft 50. When the base shaft 50 is threadedly connected to the threaded hole 152, the top end of the base shaft 50 presses the extension 112 against the stepped surface formed between the threaded hole 152 and the communicating hole 151.

[0069] The connecting nut 150 is connected to the rocker shaft 110, so that when the connecting nut 150 is connected to the base shaft 50, the base shaft 50 can be pressed against the outer extension 112 simply by rotating the connecting nut 150, thereby completing the connection between the rocker shaft 110 and the base shaft 50.

[0070] refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 11 In some embodiments, the housing 20 has a receiving cavity 201, and the rocker shaft 110 is connected to the housing 20 via at least two rotating connectors 131.

[0071] Specifically, at least two rotating connectors 131 are disposed between the housing 30 and the rocker shaft 110. The at least two rotating connectors 131 are arranged sequentially along the axial direction of the rocker shaft 110. By providing at least two rotating connectors 131, the stability of the housing 20 and the rocker shaft 110 during relative rotation can be increased.

[0072] Further, refer to Figure 11 The rocker arm shaft 110 is provided with a mounting step 113. A retaining ring 140 is provided between the mounting step 113 and the rotating connector 131. The side of the retaining ring 140 that is connected to the rocker arm shaft 110 has a beveled part 141, and the mounting step 113 has a matching beveled part 1131.

[0073] By applying an axial force to the rotating connector 131 and restricting its movement using a retaining ring 140, the rotating connector 131 is prevented from disengaging, thus achieving translational degrees of freedom other than rotation. The retaining ring 140 also absorbs axial installation tolerances of the rotating connector 131. Furthermore, the inclined surface 1131 ensures that the retaining ring 140 always abuts against the mounting step 113, thereby preventing circumferential movement. For example, see reference... Figure 11The rotating connector 131 is specifically a bearing. There are two rotating connectors 131. A retaining ring 140 is located between the mounting step 113 and the upper bearing. The retaining ring 140 abuts against the inner ring of the upper bearing.

[0074] Furthermore, the control rocker 100 also includes a shim 132. The shim 132 is disposed between the outer rings of the two bearings, so that the inner rings of the two bearings abut against each other under the axial force applied by the retaining spring 140. In this way, the rollers in the bearing move due to the movement of the inner ring while the outer ring is fixed, reducing the clearance to near zero, avoiding wobble caused by the clearance between the inner and outer rings of the bearing, and further increasing rigidity.

[0075] The shim 132 has a thickness of 0.1 mm. Its thinness allows it to be supported between the outer rings of the two bearings, leaving the inner rings suspended. Then, under the axial force applied by the snap ring 140, they abut against each other.

[0076] refer to Figure 1 , Figure 2 In some embodiments, the control joystick 100 also includes a locking structure 40. The locking structure 40 is configured to selectively connect the housing 20 and the joystick shaft 110 to restrict or release relative rotation between the housing 20 and the joystick shaft 110.

[0077] The locking structure 40 is configured to selectively connect the housing 20 and the rocker shaft 110. The locking structure 40 enables the connection between the housing 20 and the rocker shaft 110 to restrict relative rotation between them. Simultaneously, the locking structure 40 can also be disengaged from at least one of the housing 20 and the rocker shaft 110, thereby preventing relative rotation between the housing 20 and the rocker shaft 110. The specific form of the locking structure 40 is not limited.

[0078] For example, the locking structure 40 may be a latch provided on the housing 20, which can be separably engaged with the rocker arm shaft 110. Specifically, the latch is elastic and can be inserted into a groove on the rocker arm shaft 110. When a rotational force is applied to the housing 20, the housing 20 causes the latch to slide out of the groove.

[0079] By setting a locking structure 40, the rotation of the housing 20 can be locked when the control joystick 100 is not required, thus preventing accidental operation.

[0080] refer to Figure 2 and Figure 6The locking structure 40 includes a connecting rod 410 fixedly connected to the housing 20, and a positioning groove 111 that mates with the connecting rod 410 on the rocker shaft 110. For example, the housing 20 has a through hole 220. When the housing 20 and the rocker shaft 110 are further provided with a sleeve 30, the sleeve 30 has a threaded hole 320. The connecting rod 410 is specifically a screw. A limiting groove 1612 is provided on the outer wall of the rocker shaft 110. When the locking structure 40 connects the housing 20 and the rocker shaft 110, the connecting rod 410 passes through the through hole 220 and is threaded into the threaded hole 320, with the end of the connecting rod 410 extending into the positioning groove 111. Thus, the connecting rod 410 restricts the relative rotation of the housing 20 and the rocker shaft 110.

[0081] In other embodiments, the connecting rod 410 may be threaded to the housing 20 instead of the bushing 160.

[0082] refer to Figure 2 , Figure 3 and Figure 6 A second aspect of this application provides a flight simulator, which includes the control joystick 100 of any of the above embodiments. The flight simulator also includes a base, which is connected to the joystick shaft 110 via a base shaft 50.

[0083] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
