Description

Technical Field

[0001] This utility model relates to the field of cross joystick technology, specifically a cross joystick based on a Hall effect sensor. Background Technology

[0002] A cross-shaped joystick is a device that converts physical motion into electronic information, used to control vehicle speed, direction, or the operation of industrial equipment. It is commonly used in manual transmission cars, industrial machinery, and remote control systems. For example, the gearshift lever (gear lever) in a manual transmission car is a common cross-shaped joystick used to control gear shifting.

[0003] In a joystick, sensors (such as voltage dividers or optical sensors) are responsible for sensing changes in the joystick's position and converting these changes into electrical signals so that a computer can recognize and execute corresponding operations. For example, in car driving, the joystick uses position sensors to accurately sense the driver's actions, enabling precise gear shifting.

[0004] Regarding the aforementioned technical conditions, there is also the drawback that current cross joysticks generally use resistive sensors to sense changes in joystick position. Resistive sensors work by moving brushes on a resistive diaphragm to cause changes in resistance. However, the long-term movement of the brushes can lead to wear and tear on the resistive diaphragm, and may even cause it to burn out, thus shortening the lifespan of the joystick.

[0005] Based on this, this utility model designs a cross joystick based on a Hall effect sensor to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a cross joystick based on a Hall effect sensor to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cross-shaped joystick based on a Hall effect sensor, comprising a cross-shaped joystick, a mounting base, a control handle, and a rotating structure. The rotating structure is mounted on the mounting base, and the control handle is connected to the rotating structure. A Hall effect sensor is mounted on one end of the mounting base. The rotating structure includes a rotating rod, a spring, a rotating ball, and a limiting block. A rotating groove is provided at the other end of the mounting base. The rotating rod is inserted into the rotating groove, the rotating ball is fixedly connected to the rotating rod, and the control handle is fixedly connected to the rotating rod. The limiting block and the spring are both sleeved on the rotating rod, located between the rotating groove and the control handle. The limiting block abuts against the opening of the rotating groove, and the rotating ball is located between the Hall effect sensor and the mounting base. A cross-shaped groove is formed on the mounting base, communicating with the rotating groove. A positioning block is fixedly mounted on the rotating rod, and the positioning block is located in the cross-shaped groove.

[0008] Preferably, the end of the limiting block near the rotating groove is a frustum structure, and the narrow end of the limiting block abuts against the rotating groove.

[0009] Preferably, four limiting posts are fixedly provided on the rotating groove, and the limiting block is located between the four limiting posts and abuts against the limiting posts. The shape of the limiting post near the limiting block is adapted to the shape of the limiting block.

[0010] Preferably, the cross-section of the positioning block is square.

[0011] Preferably, the width of the positioning block is adapted to the width of the transverse groove of the cross groove.

[0012] Preferably, the Hall sensor includes a housing, a Hall element, a circuit board, a magnet, and a connecting wire. The circuit board is disposed in the housing, and the housing is disposed on the mounting base. One end of the connecting wire passes through the housing and is connected to the circuit board. The Hall element is connected to the circuit board. The rotating ball is disposed in the housing, and the magnet is disposed on the rotating ball. The Hall element is located below the magnet.

[0013] Preferably, the control handle is provided with a protective sleeve, the protective sleeve is connected to the mounting base, and the rotating rod is located in the protective sleeve.

[0014] In summary, this application has the following beneficial technical effects: During use, a unidirectional external force is applied to the control handle. Under the action of the external force and the combined action of the rotating ball, limiting block, spring, and rotating groove, the rotating rod approaches one of the slots in the cross-shaped groove. The direction of the magnet changes as the rotating ball rotates. The Hall element senses the change in magnetic field and generates a voltage change, thereby sensing the angle change of the control handle. When the rotating rod approaches one of the slots in the cross-shaped groove, the positioning block on the rotating rod is inserted into the slot, making the direction change of the rotating rod more stable, and the direction change of the magnetic field also more stable, improving the accuracy of the cross-shaped control lever. Simultaneously, because the magnet and the Hall element do not have direct contact, the wear and tear on the Hall element during use is reduced, thereby extending the service life of the cross-shaped control lever, achieving the effect of improving the service life of the cross-shaped control lever.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] A Hall effect sensor-based joystick includes a joystick with a mounting base 7, a control handle 1, and a rotating structure. The rotating structure is mounted on the mounting base 7, the control handle 1 is connected to the rotating structure, and a Hall effect sensor 3 is mounted on one end of the mounting base 7.

[0027] The rotating structure includes a rotating rod 11, a spring 5, a rotating ball 16, and a limiting block 6. The other end of the mounting base 7 is provided with a rotating groove 8. The rotating rod 11 is inserted into the rotating groove 8. The rotating ball 16 is fixedly connected to the rotating rod 11. The operating handle 1 is fixedly connected to the rotating rod 11. The mounting base 7 is located between the rotating ball 16 and the operating handle 1.

[0028] Both the limiting block 6 and the spring 5 are sleeved on the rotating rod 11, and are located between the rotating groove 8 and the operating handle 1. The limiting block 6 abuts against the groove on the side of the rotating groove 8 away from the rotating ball 16. One end of the spring 5 abuts against the operating handle 1, and the other end of the spring 5 abuts against the end of the limiting block 6 away from the rotating groove 8. The rotating ball 16 is located between the Hall sensor 3 and the mounting base 7. The mounting base 7 has a cross groove 15, which communicates with the rotating groove 8.

[0029] The Hall sensor 3 includes a housing 10, a Hall element 13, a circuit board 14, a magnet 17, and a connecting wire 4. The circuit board 14 is disposed within the housing 10, which is mounted on a mounting base 7. One end of the connecting wire 4 passes through the housing 10 and is connected to the circuit board 14. The Hall element 13 is connected to the circuit board 14. A rotating ball 16 is located within the housing 10, and the magnet 17 is positioned on the rotating ball 16. The Hall element 13 is located below the magnet 17, and the Hall element 13 does not have direct contact with the magnet 17.

[0030] When a unidirectional external force is applied to the control handle 1, the rotating rod 11 moves closer to one of the slots of the cross groove 15 under the action of the external force and the interaction of the rotating ball 16, the limiting block 6, the spring 5 and the rotating groove 8. The direction of the magnet 17 changes with the rotation of the rotating ball 16. The Hall element 13 senses the change in the magnetic field and generates a voltage change, thereby sensing the angle change of the control handle 1.

[0031] When the external force applied to the control handle 1 disappears, the rotating rod 11 and the control handle 1 return to their original positions under the action of the spring 5. The magnet 17 does not make direct contact with the Hall element 13, reducing the wear and tear on the Hall element 13 during use, thereby extending the service life of the cross control lever.

[0032] A positioning block 12 is fixedly mounted on the rotating rod 11, and the positioning block 12 is located in the cross groove 15. The positioning block 12 has a square cross-section, and its width is adapted to the width of the transverse slot of the cross groove 15. When a unidirectional external force is applied to the operating handle 1, the rotating rod 11 moves closer to one of the slots of the cross groove 15 under the action of the external force, and the positioning block 12 is inserted into the slot. With the structural arrangement of the positioning block 12, the positioning block 12 can be stably inserted into the slot of the cross groove 15, and the rotating rod 11 stably deflects in the direction of the slot, increasing the stability of the change in the direction of the magnetic field of the magnet 17, thereby improving the accuracy of the cross operating lever.

[0033] The end of the limiting block 6 near the rotating groove 8 is a frustum structure, and the narrow end of the limiting block 6 abuts against the rotating groove 8. Four limiting posts 9 are fixedly installed on the rotating groove 8, and the limiting block 6 is located between the four limiting posts 9 and abuts against the limiting posts 9. The shape of the limiting post 9 near the limiting block 6 is adapted to the shape of the limiting block 6.

[0034] With the cooperation of the frustum shape at one end of the limiting block 6 and the limiting post 9, as well as the combined action of the rotating ball 16 and the spring 5, the rotating rod 11 can rotate on the mounting base 7. Due to the frustum shape of the limiting block 6 and the restriction of the four limiting posts 9, the rotation range of the rotating rod 11 is limited between the rotating groove 8 and the four limiting posts 9.

[0035] A protective sleeve 2 is fitted onto the control handle 1, and the protective sleeve 2 is connected to the mounting base 7. The rotating rod 11 is located inside the protective sleeve 2. The protective sleeve 2 serves to protect and prevent external debris from entering the protective sleeve 2 and affecting the rotation effect of the rotating structure.

[0036] The implementation principle of this embodiment is as follows: During use, a unidirectional external force is applied to the control handle 1. Under the action of the external force and the interaction of the rotating ball 16, the limiting block 6, the spring 5, and the rotating groove 8, the rotating rod 11 moves closer to one of the slots in the cross groove 15. The direction of the magnet 17 changes with the rotation of the rotating ball 16. The Hall element 13 senses the change in the magnetic field and generates a voltage change, thereby sensing the angle change of the control handle 1. When the rotating rod 11 moves closer to one of the slots in the cross groove 15, the positioning block 12 on the rotating rod 11 is inserted into the slot of the cross groove 15, making the direction change of the rotating rod 11 more stable and the direction change of the magnetic field more stable, thus improving the accuracy of the cross control lever. At the same time, since the magnet 17 does not make direct contact with the Hall element 13, the wear and tear on the Hall element 13 during use is reduced, thereby extending the service life of the cross control lever and achieving the effect of improving the service life of the cross control lever.
