Abstract
Claims
1. A speed control device electrically connected to an external device for receiving and outputting control signals related to the external device, comprising: a housing; a control circuit unit disposed within the housing; a panel disposed on one side of the housing; a display module disposed on the panel and electrically connected to the control circuit unit, the display module including a numerical display area; and an operation module disposed on the panel and separately configured from the display module, the operation module being electrically connected to the control circuit unit.
2. The speed control device as described in claim 1, wherein, The display module also includes a status indicator area located adjacent to the numerical display area.
3. The speed control device as described in claim 2, wherein, The status indicator area is equipped with a status indicator light, which is configured to remain constantly lit when the external device is in a normal state, and to flash when the external device is in an abnormal state.
4. The speed control device as described in claim 2, wherein, The status indicator area is equipped with an operation indicator light. When the external device is operating normally, the operation indicator light is constantly lit.
5. The speed control device as described in claim 2, wherein, The status indicator area is equipped with an abnormal indicator light. When the external device is operating abnormally, the abnormal indicator light will be constantly lit.
6. The speed control device as described in claim 1, wherein, The operation module includes at least one speed selection button, which corresponds to a preset speed value.
7. The speed control device as described in claim 6, wherein, There are multiple speed selection buttons, each corresponding to a different preset RPM value.
8. The speed control device as described in claim 1, wherein, The operation module includes an acceleration button and a deceleration button, which are set separately from each other.
9. The speed control device as described in claim 1, wherein, The operation module includes a start / stop operation button structure, which is an integrated button.
10. The speed control device as described in claim 1, wherein, The operating module includes a start button and a stop button that are set separately from each other.
11. The speed control device as described in claim 1, wherein, The operating module includes a unit selection button to switch between displaying the unit of rotational speed or the unit of linear velocity.
12. The speed control device as described in claim 1, wherein, The operation module includes a reset button, which is used to restore the system from an abnormal state to a normal state.
13. The speed control device as claimed in claim 1 further includes at least one snap-fit structure disposed on the outer periphery of the housing and forming a snap-fit portion corresponding to an opening or an edge of an outer plate.
14. The speed control device as described in claim 13, wherein, The latching structure includes a first locking portion and a second locking portion spaced apart from each other, and a clamping space is defined between their opposing ends, the size of which is suitable for accommodating a portion of the outer plate.
15. The speed control device as described in claim 14, wherein, The latching structure also includes an elastic arm extending away from the housing, and one end of the elastic arm is provided with the first locking portion.
16. The speed control device as described in claim 15, wherein, The first locking part includes a plurality of sequentially arranged stepped stops, and each stepped stop has a height difference from each other, so that each stepped stop forms an engagement position corresponding to an outer plate of different thickness.
17. The speed control device as described in claim 14, wherein, The latching structure also includes a protrusion surrounding one side of the housing, and a portion of the protrusion constitutes the second locking portion.
18. The speed control device as described in claim 1, wherein, The control circuit unit includes a pluggable terminal block disposed on the housing and having a plurality of wiring terminals for connection of an external wire.
19. The speed control device as described in claim 1, wherein, The control circuit unit includes a signal output unit, which includes at least one output terminal independent of the communication control. The output terminal is electrically connected to the control circuit unit and outputs different control signals corresponding to different operating states of the speed control device.
20. The speed control device as described in claim 19, wherein, The signal output unit is selected from one or a combination of the following: a relay, a solid-state relay (SSR), a transistor switch (BJT, MOSFET or IGBT) or a controlled silicon switch (TRIAC or SCR).
