Description

Technical Field

[0001] This utility model relates to the field of rotary switch technology, specifically to a gear rotary switch and its application device. Background Technology

[0002] Multi-position rotary switches are a common type of switch in electrical equipment, widely used in electronic devices. Most common rotary switches utilize a rotating component and a stationary component in operation. The stationary component can be designed with recesses or protrusions as needed, while the rotating component can be designed with corresponding protrusions or recesses to engage with the stationary component. With the interaction of the recesses and protrusions, the rotary switch can engage in different positions on the stationary component to generate corresponding functional commands. However, users of this type of rotary switch must exert considerable force to overcome the resistance between the protrusions and recesses to engage the rotating component and the stationary component in different positions. Therefore, excessive force often causes the rotating component to over-rotate, making it difficult to accurately position the rotary switch to the preset position.

[0003] Therefore, it is necessary to provide a gear selector switch and application device that is easy to rotate and has a simple structure. Utility Model Content

[0004] The main purpose of this utility model is to provide a gear shift knob switch and its application device to solve the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A gear selector rotary switch includes a housing. The inner wall of the housing is provided with a stepped layer wall and a limiting plate. The stepped layer wall includes a first stepped layer, a second stepped layer, and a third stepped layer connected in sequence. The wall thickness of the first stepped layer, the second stepped layer, and the third stepped layer decreases in sequence. The limiting plate is connected between the first stepped layer and the third stepped layer. An elastic roller pressure measuring component is rotatably connected inside the housing. The end of the elastic roller pressure measuring component abuts against the stepped layer wall.

[0007] Furthermore, there are gentle curve structures connecting the first and second step layers, and between the second and third step layers.

[0008] Furthermore, the elastic roller pressure measuring assembly includes a rotating column, which is rotatably connected to the inside of the housing, with one end of the rotating column penetrating through the top of the housing. A sleeve is connected to the side wall of the rotating column, and a sliding rod is slidably connected inside the sleeve. A pressure monitoring element is provided inside the sleeve, and a spring is connected between the sliding rod and the pressure monitoring element. A roller is rotatably connected to the end of the sliding rod extending out of the sleeve.

[0009] Furthermore, a protruding plate is provided at the end of the rotating column that penetrates the housing.

[0010] An application device for a gear rotary switch is provided. The application device is a fresh air system. The gear rotary switch is used. The elastic roller pressure measuring component is electrically connected to the PLC of the fresh air system, and the intake air speed is controlled by the PLC.

[0011] An application device for a gear-position rotary switch is disclosed. The application device is a fresh air system. The gear-position rotary switch is used, and the elastic roller pressure measuring component is electrically connected to the PLC of the fresh air system. The PLC controls the opening and closing angle of the air inlet.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] With its simple structure and convenient connection, it eliminates the need for multiple wiring connections. The smooth rotation is achieved solely through the stepped walls inside the housing and the elastic roller pressure measuring component.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] Combination Figure 1-6 This utility model provides a gear knob switch, including a housing 1. The inner wall of the housing 1 is provided with a stepped layer wall 2 and a limiting plate 3. The stepped layer wall 2 includes a first stepped layer 21, a second stepped layer 22 and a third stepped layer 23 connected in sequence. The wall thickness of the first stepped layer 21, the second stepped layer 22 and the third stepped layer 23 decreases in sequence. The limiting plate 3 is connected between the first stepped layer 21 and the third stepped layer 23. An elastic roller pressure measuring component 4 is rotatably connected inside the housing 1. The end of the elastic roller pressure measuring component 4 abuts against the stepped layer wall 2.

[0024] The limiting plate 3 can limit the rotational position of the elastic roller pressure limiting component 4.

[0025] The first step layer 21 and the second step layer 22, and the second step layer 22 and the third step layer 23 are all connected by a gentle curve structure, which can ensure that the elastic roller pressure measuring component 4 moves stably between different step layers.

[0026] The elastic roller pressure measuring assembly 4 includes a rotating column 41, which is rotatably connected to the inside of the housing 1. The rotating column 41 and the housing 1 can be rotatably connected by a bearing to reduce friction. One end of the rotating column 41 passes through the top of the housing 1. A sleeve 42 is connected to the side wall of the rotating column 41. A slide rod 43 is slidably connected inside the sleeve 42. A pressure monitoring element 44 is provided inside the sleeve 42. A spring 45 is connected between the slide rod 43 and the pressure monitoring element 44. A roller 46 is rotatably connected to the end of the slide rod 43 that extends out of the sleeve 42.

[0027] The roller 46 abuts against the stepped layer wall 2 under the elastic action of the spring 45. The elastic force of the spring 45 can ensure that the position of the elastic roller pressure measuring component 4 is fixed when the rotating column 41 is not actively rotated. When the roller abuts against the first stepped layer 21, the second stepped layer 22 and the third stepped layer 23 respectively, the spring 45 is subjected to different compressive forces. The pressure monitoring component 44 detects different pressure values. Different gear signals can be corresponding to the three different pressure values. By connecting the pressure monitoring component 44 to the PLC, the PLC controls the corresponding device to work at different gears according to different pressure values, without the need to achieve multi-gear control through relays and other multi-wire components.

[0028] The rotating column 41 has a protruding plate (not shown in the figure) provided on the end side wall of the housing 1 to facilitate the rotation of the rotating column 41.

[0029] The rotary switch of this utility model has a simple structure and is easy to connect. It does not require multiple wiring. It only uses the stepped wall inside the housing in conjunction with the elastic roller pressure measuring component to control the rotation smoothly. The pressure measured at different steps is different. The PLC connected to the rotary switch can control the application device according to different pressures to realize multi-level control, which is more practical.

[0030] Example 2

[0031] An application device for a gear rotary switch is provided. The application device is a fresh air system. The gear rotary switch is used. The elastic roller pressure measuring component is electrically connected to the PLC of the fresh air system. The PLC controls the intake air speed. When the elastic roller pressure measuring component 4 of the gear rotary switch is at different steps, the pressure monitoring component 44 can detect different pressure values. According to different pressure values, the intake air speed can be controlled in multiple levels.

[0032] Example 3

[0033] An application device for a gear-position rotary switch is disclosed. The application device is a fresh air system. The gear-position rotary switch is used. The elastic roller pressure measuring component is electrically connected to the PLC of the fresh air system. The PLC controls the opening and closing angle of the air inlet. When the elastic roller pressure measuring component 4 of the gear-position rotary switch is at different steps, the pressure monitoring element 44 can detect different pressure values. Based on different pressure values, multi-level control of the opening and closing angle of the air inlet can be realized.

[0034] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
