Description

Technical Field

[0001] This invention belongs to the field of industrial joystick technology, and specifically relates to an industrial joystick device. Background Technology

[0002] In existing industrial joystick devices, the mechanical connections and electrical components are housed together in a cavity. In open-air operations, especially in high-temperature and humid environments such as mountainous areas, rainforests, or offshore oil platforms, water vapor can easily enter the cavity through the lever's movement gap. At the same time, due to temperature differences, water vapor can easily condense inside the cavity, leading to short circuits or corrosion failures in the electrical components, causing the industrial joystick to malfunction. Summary of the Invention

[0003] This invention provides an industrial joystick device to overcome the shortcomings of the prior art.

[0004] The technical solution adopted in this invention is as follows: an industrial joystick device, including a base, a first cavity and a second cavity are provided in the base, a gear seat is fixed in the first cavity, a gear is installed in the gear seat through a horizontal rotating shaft, and a first magnet is fixed at one end of the horizontal rotating shaft; a first handle is oscillatingly connected to the top of the first cavity, and the lower end of the first handle extends into the first cavity and is fixed with a sector rack, so that the sector rack meshes with the gear; a first Hall sensor and a control circuit board are fixed in the second cavity, and the first Hall sensor is electrically connected to the control circuit board and is positioned close to the first magnet.

[0005] The first handle is fitted with a second handle that can slide up and down, and a second magnet is fixedly connected to the lower outer side of the second handle; a second Hall sensor that is electrically connected to the control circuit board is fixed in the second cavity, and the second Hall sensor and the second magnet are close to each other when the second handle is in the initial position.

[0006] The other end of the horizontal rotating shaft is fixed with a limiting plate, and the limiting plate has an arc-shaped limiting groove. The end face of the gear seat relative to the limiting plate is fixed with a limiting pin. The two sides of the limiting plate are connected to the gear seat by tension springs arranged symmetrically, and the limiting pins extend into the arc-shaped limiting groove.

[0007] A compression spring is provided between the first handle and the second handle, which automatically resets the second handle to its initial state.

[0011] An emergency stop switch is installed at the top of the second cavity.

[0012] A temperature protector is installed inside the second cavity.

[0013] The second cavity is filled with epoxy resin.

[0014] Compared with the prior art, the present invention has the following advantages and effects:

[0015] 1. This invention overcomes the problem of water vapor entering the cavity through the handle's movement gap, which could cause short circuits or corrosion of the electrical components, by separating the mechanical connection and electrical components into two isolated cavities, thus ensuring the normal operation of the industrial joystick.

[0016] 2. This invention improves the sealing effect of electrical components by using a potting material to pot the cavity of the electrical components.

[0023] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in detail below with reference to specific embodiments.

[0024] An industrial joystick device includes a base 1, which has a first cavity 1-1 and a second cavity 1-2. A gear seat 2 is fixed in the first cavity 1-1, and a gear 4 is mounted in the gear seat 2 via a horizontal rotating shaft 3. A first magnet 5 is fixed to one end of the horizontal rotating shaft 3. A first handle 6 is oscillatingly connected to the top of the first cavity 1-1, and the lower end of the first handle 6 extends into the first cavity 1-1 and is fixed with a sector rack 9, which meshes with the gear 4. A first Hall sensor 10 and a control circuit board 12 are fixed in the second cavity 1-2, and the first Hall sensor 10 is electrically connected to the control circuit board 12 and is positioned close to the first magnet 5.

[0025] A second handle 7, which can slide up and down, is fitted around the first handle 6, and a second magnet 8 is fixedly connected to the lower outer side of the second handle 7. A second Hall sensor 11, which is electrically connected to the control circuit board 12, is fixed inside the second cavity 1-2, and the second Hall sensor 11 and the second magnet 8 are close together when the second handle 7 is in the initial position. A compression spring 15 is provided between the first handle 6 and the second handle 7, which automatically resets the second handle 7 to the initial state, ensuring that the second Hall sensor 11 and the second magnet 8 are close together when the second handle 7 is in the initial position.

[0026] The other end of the horizontal rotating shaft 3 is fixed with a limiting plate 16, and the limiting plate 16 has an arc-shaped limiting groove 16-1. The end face of the gear seat 2 opposite to the limiting plate 16 is fixed with a limiting pin 2-3. The two sides of the limiting plate 16 are connected to the gear seat 2 by symmetrically arranged tension springs 17, and the limiting pins 2-3 extend into the arc-shaped limiting groove 16-1. The swing angle of the first handle 6 is limited by the cooperation of the limiting pins 2-3 and the arc-shaped limiting groove 16-1. The tension springs 17 cause the first handle 6 and the second handle 7 to automatically return to the vertical position.

[0027] When this invention is used to control an electric winch, the three actions of forward and reverse operation and stopping the electric winch can be achieved by manually operating the first handle 6 and the second handle 7. In the initial state, the first handle 6 and the second handle 7 are in the vertical position. The second Hall sensor 11 and the second magnet 8 sense and output a switch signal, causing the electric winch to brake and stop. After manually sliding the second handle 7 upward and swinging the first handle 6 clockwise (or counterclockwise), the second magnet 8 is moved away from the second Hall sensor 11, the electric winch brake is released, and the sector rack 9 drives the gear 4 to rotate, causing the first magnet 5 to rotate relative to the first Hall sensor 10. The first Hall sensor 10 outputs an analog signal, which is then converted into a control signal by the control circuit board 12 to control the electric winch to operate in the forward (or reverse) direction. After the forward (or reverse) operation ends, the first handle 6 and the second handle 7 automatically return to the vertical position under the action of the tension spring 17. At the same time, under the action of the compression spring 15, the second handle 7 returns to the initial position, and the second magnet 8 and the second Hall sensor 11 sense and output a switch signal again, causing the electric winch brake and stop.

[0028] To ensure that the swinging of the first handle 6 and the sliding of the second handle 7 do not interfere with each other, a flange 20 is fixed to the top of the first cavity 1-1, and the lower part of the first handle 6 is sway-connected to the flange 20 via a hinge shaft 18. The lower part of the first handle 6 is provided with a first slotted hole 6-1, and the lower part of the second handle 7 is provided with a second slotted hole 7-1 and a horizontally fixed pin 19, with the hinge shaft 18 passing through the upper part of the second slotted hole 7-1 and the pin 19 passing through the lower part of the first slotted hole 6-1. By setting the first slotted hole 6-1 to accommodate the pin 19 and the second slotted hole 7-1 to accommodate the hinge shaft 18, the swinging of the first handle 6 and the sliding of the second handle 7 do not interfere with each other.

[0029] To ensure that the second handle 7 is automatically reset to its initial state by the compression spring 15 and that the second Hall sensor 11 and the second magnet 8 are positioned close together, the gear seat 2 has a V-groove 2-1 at its top, and a limiting groove 2-2 at the bottom of the V-groove 2-1. The V-groove 2-1 ensures that when the compression spring 15 automatically resets the second handle 7 to its initial state, both ends of the pin 19 automatically engage with the limiting groove 2-2, and the second magnet 8 is fixed to the end of the pin 19, thereby ensuring that the second Hall sensor 11 and the second magnet 8 are positioned close together.

[0030] In a preferred embodiment, the base 1 is rectangular, and the base 1 is divided into a first cavity 1-1 and a second cavity 1-2 by an L-shaped partition wall 1-3, so that the cross-section of the first cavity 1-1 is L-shaped and the cross-section of the second cavity 1-2 is rectangular; the horizontal rotating shaft 3, the hinge shaft 18, and the pin shaft 19 are all arranged perpendicular to the long side of the base 1; the first Hall sensor 10 and the second Hall sensor 11 are both fixed on the outside of the same side of the L-shaped partition wall 1-3, and the second Hall sensor 11 is located above the first Hall sensor 10, with the first Hall sensor 10 arranged opposite to the first magnet 5 and the second Hall sensor 11 arranged opposite to the second magnet 8.

[0031] To prevent dust from entering the first cavity 1-1, a spherical sleeve 21 is installed between the second handle 7 and the flange 20. A protective sleeve 23 is installed around the second handle 7. The upper end of the protective sleeve 23 is connected to the upper part of the first handle 6, and the lower end is connected to the top of the base 1, thus enclosing the second handle 7 and the flange 20 inside the protective sleeve 23.

[0032] In order to cut off the main power supply in an emergency and improve safety, an emergency stop switch 13 is installed on the top of the second cavity 1-2, and the emergency stop switch 13 is connected in series with the main power line. In an emergency, pressing the emergency stop switch 13 will cut off the main power supply.

[0033] To prevent electrical faults caused by excessive temperature inside the base, a temperature protector 14 is installed in the second cavity 1-2, and the temperature protector 14 is connected in series with the power supply line. It is used to monitor the temperature inside the base; if the temperature inside the base exceeds 50°C during use, the power supply will be automatically cut off to prevent electrical faults.

[0034] To improve insulation and sealing performance and enhance waterproofing, the second cavity 1-2 is filled with epoxy resin to insulate and seal the first Hall sensor 10, the second Hall sensor 11, the control circuit board 12, and the temperature protector 14. Alternatively, the second cavity 1-2 may be filled with other materials such as silicone rubber.

[0035] For ease of installation, the first cavity 1-1 has an open side for installing the limiting plate 16, and the second cavity 1-2 has an open side for installing the first Hall sensor 10 and the second Hall sensor 11. After the overall assembly is completed, the open side is closed by the sealing installation cover plate 22.

[0036] In specific applications, a cable guard 24 is installed on the inlet hole of the side wall of the second cavity 1-2 to fix and protect the cable and prevent the cable from being pulled out, pushed out or twisted.

[0037] It should be noted that this invention is not limited to controlling electric winches, but can also be used to control other equipment with the same requirements.

[0038] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent variations made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
