Description

Technical Field

[0001] The utility model relates to the technical field of joysticks, in particular to a double-axis joystick. Background Art

[0002] A joystick is a physical device that converts the movement of a plastic rod into electronic information that can be processed by a computer. Commonly used industrial joysticks include Hall joysticks and potentiometer joysticks.

[0003] Joysticks are roughly divided into single-axis joysticks and dual-axis joysticks. Specifically, single-axis joysticks are mostly described in the text of a joystick with Chinese patent publication number CN220137597U, in which the swing arm swings only around a single shaft, and the angle between the magnet installed at the axis of the shaft and the Hall effect chip changes, so that the Hall effect chip senses the change in magnetic field intensity and generates a correspondingly changing electrical signal. Dual-axis joysticks are mostly described in the text of a dual-axis Hall joystick with Chinese patent publication number CN110471489A, in which the lower end of the shaft is set as a sphere, and the magnet is set in the sphere. The swing arm and the sphere can realize rotation in the X-axis and Y-axis directions, thereby realizing dual-path signal transmission. Since the single-axis joystick only swings in one direction, the control operation is relatively stable. However, in the dual-axis joystick, when the swing arm swings in the X-axis direction and drives the magnet to move in the X-axis direction, it will inevitably interfere with the Hall effect chip that senses the change of magnetic field strength in the Y-axis direction, resulting in a decrease in the control accuracy of the joystick, which needs to be solved urgently. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a dual-axis joystick, in which the swinging processes of the swing rod in the X-axis and Y-axis directions are independent of each other and do not interfere with each other, thereby effectively improving the control accuracy of the joystick.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A dual-axis joystick comprises a base and a swing rod swingably mounted on the base, wherein an X-axis rod and a Y-axis rod respectively distributed along the horizontal X-axis direction and the horizontal Y-axis direction are installed in the base, the middle part of the Y-axis rod is bent outward to form a U-shaped groove cavity, the X-axis rod is located at the notch of the U-shaped groove cavity, and the axis of the X-axis rod and the axis of the Y-axis rod are perpendicular to each other and located on the same horizontal plane, magnetic steel is installed at the axis center of one end of the X-axis rod and one end of the Y-axis rod, and a Hall chip coaxially distributed with the magnetic steel is arranged on the side wall of the base adjacent to each magnetic steel, a first long hole and a second long hole penetrating from top to bottom are respectively arranged on the X-axis rod and the Y-axis rod, the hole length directions of the first long hole and the second long hole are respectively distributed along the axial direction of the X-axis rod and the Y-axis rod, the lower end of the swing rod simultaneously penetrates the first long hole and the second long hole, the joystick is also provided with a pin radially penetrating the X-axis rod and the swing rod, and the pin is coaxially arranged along the axis of the Y-axis rod.

[0007] As a further solution of the utility model: the base is composed of an upper mounting seat, a middle mounting seat and a lower mounting seat arranged in sequence from top to bottom, the lower mounting seat and the middle mounting seat are penetrated in sequence by bolts distributed in the vertical direction and assembled to the upper mounting seat, the adjacent ends of the upper mounting seat and the middle mounting seat are provided with semicircular grooves on all four sides, and after the upper mounting seat and the middle mounting seat are combined, the semicircular grooves on the same side are enclosed to form a mounting hole for clamping the end of the X-axis rod or the Y-axis rod.

[0008] As a further solution of the utility model: the magnetic steel is arranged in the grooves at the ends of the X-axis rod and the Y-axis rod, and a baffle is fixed on the lower mounting seat to prevent the magnetic steel from separating from the groove.

[0009] As a further solution of the utility model: the outer wall of the baffle is provided with a Hall slot for accommodating the Hall chip, the Hall chip is sealed in the Hall slot by a mounting plate, and the mounting plate is fixed to the baffle by screws.

[0010] As a further solution of the utility model: an axial hole connected to the end groove of the Y-axis rod is coaxially arranged on the Y-axis rod, the pin is arranged in the axial hole, and the pin is locked in the axial hole by a magnet and a baffle.

[0011] As a further solution of the present invention: both ends of the X-axis rod and the Y-axis rod are sleeved with shaft sleeves, and the shaft sleeves are clamped in the mounting holes.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the pendulum swings along the X-axis or Y-axis, it only drives the Y-axis rod and the X-axis rod to rotate, and the Hall chips corresponding to the magnets at the ends of the Y-axis rod and the X-axis rod respectively sense the magnetic field changes, thus avoiding magnetic field interference during the swing of the pendulum along the X-axis or Y-axis and affecting the accuracy of the joystick.

[0014] 2. When assembling the X-axis rod and the Y-axis rod, place the two ends of the Y-axis rod in the two semicircular grooves on the opposite sides of the middle mounting seat. Thereafter, place the two ends of the X-axis rod in the other two semicircular grooves of the middle mounting seat. Finally, the lower mounting seat and the middle mounting seat are penetrated in sequence by bolts distributed in the vertical direction and assembled to the upper mounting seat. The semicircular grooves also arranged on the upper mounting seat at the corresponding positions of the middle mounting seat form mounting holes for clamping the ends of the X-axis rod or the Y-axis rod. In this way, the ends of the X-axis rod and the Y-axis rod can be clamped and fixed during the assembly process of the upper mounting seat and the middle mounting seat, thereby improving the installation efficiency of the X-axis rod and the Y-axis rod.

[0015] 3. The magnet is arranged in the grooves at the ends of the X-axis rod and the Y-axis rod, and a baffle is fixed on the lower mounting seat to prevent the magnet from being separated from the groove. Therefore, after the magnet is placed in the groove, the baffle on the lower mounting seat can block the magnet in the groove when the lower mounting seat is assembled with the middle mounting seat and the upper mounting seat, thereby realizing the assembly operation of the magnet and effectively improving the efficiency of the magnet installation.

[0016] 4. An axial hole connected to the groove at the end of the Y-axis rod is coaxially arranged on the Y-axis rod, and a pin is arranged in the axial hole so that the pin can pass through the groove at the end of the Y-axis rod and radially penetrate the X-axis rod and the rocker arm to achieve the connection between the Y-axis rod, the X-axis rod and the rocker arm. Finally, the pin is locked in the axial hole by a magnet and a baffle, further improving the convenience of installation between the Y-axis rod, the X-axis rod and the rocker arm.

[0017] 5. The outer wall of the baffle is provided with a Hall slot for accommodating the Hall chip. The Hall chip is sealed in the Hall slot by a mounting plate, and the mounting plate is fixed to the baffle by screws. This installation method is efficient and convenient, and can be installed after the base is assembled. In addition, when the Hall chip fails, only the mounting plate and the Hall chip need to be removed, which also improves the convenience of repairing and disassembling the Hall chip.

[0018] 6. Both ends of the X-axis rod and the Y-axis rod are provided with shaft sleeves, which are clamped in the mounting holes. Specifically, the shaft sleeves can be made of wear-resistant materials, which can effectively reduce the wear on the walls of the mounting holes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For ease of understanding, the specific structure and working mode of the utility model are further described below in conjunction with the accompanying drawings:

[0027] The specific structure of the utility model refers to Figure 1-5 As shown, its main structure includes a base 30 and a swing rod 20 swingably mounted on the base 30. Among them, an X-axis rod 40 and a Y-axis rod 50 are installed in the base 30, which are distributed along the horizontal X-axis direction and the horizontal Y-axis direction respectively. A magnet 60 is installed at the axis of one end of the X-axis rod 40 and one end of the Y-axis rod 50, and a Hall chip 70 coaxially distributed with the magnet 60 is arranged on the side wall of the base 30 near each magnet 60, so that when the X-axis rod 40 and the Y-axis rod 50 rotate around their own axes respectively, they can drive the magnet 60 at their own ends to rotate, and the Hall chip 70 corresponding to the magnet 60 senses the magnetic field change. Specifically, as Figure 2 As shown, the middle portion of the Y-axis rod 50 is bent outward to form a U-shaped groove cavity, such as Figure 1As shown, the X-axis rod 40 is located at the notch of the U-shaped groove cavity, and the axis of the X-axis rod 40 and the axis of the Y-axis rod 50 are perpendicular to each other and are located on the same horizontal plane. The X-axis rod 40 and the Y-axis rod 50 are respectively provided with a first long hole 41 and a second long hole 51 that pass through from top to bottom. The hole length directions of the first long hole 41 and the second long hole 51 are respectively distributed along the axial direction of the X-axis rod 40 and the Y-axis rod 50. The lower end of the rocker rod 20 passes through the first long hole 41 and the second long hole 51 at the same time, and a pin 81 that radially passes through the X-axis rod 40 and the rocker rod 20 is arranged along the axial direction of the Y-axis rod 50. During use, when the swing arm 20 is controlled to swing along the Y-axis direction, since the X-axis rod 40 and the swing arm 20 are radially penetrated by the pin 81 at the same time, the swing arm 20 will drive the X-axis rod 40 to rotate along the Y-axis direction. At the same time, since the second long hole 51 is distributed along the length direction of the hole pattern set on the Y-axis rod 50, during the swinging process of the swing arm 20 along the Y-axis direction, it will slide in the second long hole 51 along the length direction of the hole pattern of the second long hole 51, so that the swinging of the swing arm 20 along the Y-axis direction only drives the X-axis rod 40 to rotate, and will not drive the Y-axis rod 50 to move or rotate. In addition, when the swing rod 20 is controlled to swing along the X-axis direction, since the X-axis rod 40 and the swing rod 20 are radially penetrated by the pin 81 at the same time, and the pin 81 is arranged along the axial direction of the Y-axis rod 50, the swing axis of the swing rod 20 along the X-axis direction is the axis of the pin 81 (i.e., the axis of the Y-axis rod 50); and since the swing rod 20 penetrates the second long hole 51 on the Y-axis rod 50, when the swing rod 20 swings along the X-axis direction, it will push the side wall of the second long hole 51, and then push the Y-axis rod 50 to rotate along the X-axis direction. In addition, during the swinging process of the swing rod 20 along the X-axis direction, it will slide in the first long hole 41 along the length direction of the hole pattern of the first long hole 41, so that the swinging of the swing rod 20 along the X-axis direction only drives the Y-axis rod 50 to rotate, and will not drive the X-axis rod 40 to move or rotate. In summary, when the pendulum 20 swings along the X-axis or Y-axis, it only drives the Y-axis rod 50 and the X-axis rod 40 to rotate respectively, and the Hall chips 70 corresponding to the magnets 60 at the ends of the Y-axis rod 50 and the X-axis rod 40 respectively sense the magnetic field changes, thereby avoiding magnetic field interference during the swing of the pendulum 20 along the X-axis or Y-axis and affecting the accuracy of the joystick.

[0028] In order to improve the convenience of the assembly of the joystick, on the basis of the above, Figure 4 and Figure 5As shown, the base 30 is composed of an upper mounting seat 31, a middle mounting seat 32 and a lower mounting seat 33 which are arranged in sequence from top to bottom, and semicircular grooves 35 are provided on the four sides of the adjacent ends of the upper mounting seat 31 and the middle mounting seat 32. After the upper mounting seat 31 and the middle mounting seat 32 are combined, the semicircular grooves 35 on the same side are enclosed to form a mounting hole for clamping the end of the X-axis rod 40 or the Y-axis rod 50. Therefore, when assembling the X-axis rod 40 and the Y-axis rod 50, the two ends of the Y-axis rod 50 are placed in the two semicircular grooves 35 on the opposite sides of the middle mounting seat 32. Thereafter, the two ends of the X-axis rod 40 are placed in the other two semicircular grooves 35 of the middle mounting seat 32. Finally, the lower mounting seat 33 and the middle mounting seat 32 are penetrated in sequence by bolts 36 distributed in the vertical direction and assembled to the upper mounting seat 31. The semicircular grooves 35 also arranged at the corresponding positions of the upper mounting seat 31 and the middle mounting seat 32 form mounting holes for clamping the ends of the X-axis rod 40 or the Y-axis rod 50. In this way, the ends of the X-axis rod 40 and the Y-axis rod 50 can be clamped and fixed during the assembly process of the upper mounting seat 31 and the middle mounting seat 32.

[0029] In addition, if Figure 5 As shown, both ends of the X-axis rod 40 and the Y-axis rod 50 are sleeved with shaft sleeves 34, and the shaft sleeves 34 are clamped in the mounting holes. Specifically, the shaft sleeves 34 can be made of wear-resistant material, which can effectively reduce the wear on the wall of the mounting hole.

[0030] Further, such as Figure 4 and Figure 5 As shown, the magnet 60 is arranged in the grooves at the ends of the X-axis rod 40 and the Y-axis rod 50, and a baffle 331 is fixed on the lower mounting seat 33 to prevent the magnet 60 from being separated from the groove. Therefore, after the magnet 60 is placed in the groove, when the lower mounting seat 33 is assembled with the middle mounting seat 32 and the upper mounting seat 31, the baffle 331 on the lower mounting seat 33 blocks the magnet 60 in the groove, thereby realizing the assembly operation of the magnet 60. In addition, an axial hole connected to the end groove of the Y-axis rod 50 is coaxially arranged on the Y-axis rod 50, and a pin 81 is arranged in the axial hole, so that the pin 81 can pass through the end groove of the Y-axis rod 50 to enter the axial hole, and radially penetrate the X-axis rod 40 and the rocker rod 20, so as to realize the connection between the Y-axis rod 50, the X-axis rod 40 and the rocker rod 20. Finally, the pin 81 is locked in the axial hole by the magnet 60 and the baffle 331, so as to further improve the convenience of installation between the Y-axis rod 50, the X-axis rod 40 and the rocker rod 20.

[0031] On the basis of the above, if Figure 5As shown, the outer wall of the baffle 331 is provided with a Hall slot for accommodating the Hall chip 70, and the Hall chip 70 is sealed in the Hall slot by the mounting plate 332, and the mounting plate 332 is fixed to the baffle 331 by screws 333. Therefore, after the installation of the components such as the magnetic steel 60, the Y-axis rod 50, the X-axis rod 40 and the swing rod 20, the Hall chip 70 can be installed in the Hall slot of the outer wall of the baffle 331, and the mounting plate 332 can be locked in the notch of the Hall slot by screws 333 to achieve the installation of the Hall chip 70. This installation method is efficient and convenient, and when the Hall chip 70 fails, it is only necessary to disassemble the mounting plate 332 and the Hall chip 70, which also improves the convenience of repair and disassembly of the Hall chip 70.
