Description

Technical Field

[0001] The utility model relates to a potentiometer, in particular to a lever type potentiometer. Background Art

[0002] At present, the existing potentiometers mainly include rocker potentiometers, rotary shaft potentiometers, button potentiometers, etc. Rocker potentiometers are used for handle rockers, rotary shaft potentiometers are used for knob switches, and button potentiometers are used for ordinary buttons. Moreover, when used for trigger buttons of game controllers, a connecting rod mechanism needs to be added. The pressing direction can be changed by the connecting rod mechanism to match the use, which is inconvenient. Obviously, each of the aforementioned types of potentiometers can only adapt to one usage scenario, and different potentiometers need to be used in different usage scenarios. At the same time, since the aforementioned types of potentiometers are generally large in size and thickness, they are difficult to use on ultra-thin products. Therefore, the development of a lever-type potentiometer with a wider range of applications has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Example 1: Figure 1 , Figure 2 As shown, a lever type potentiometer comprises a housing 1, a PCB board 2 is arranged in the housing 1, the PCB board 2 is provided with a pin 201, a resistance value sensing element is arranged on the PCB board 2, a vertically swinging lever 4 is arranged in the housing 1, one end of the lever 4 extends to the outside of the housing 1 to form a swinging driving end, the fulcrum of the lever 4 is arranged at the inner end of the lever 4, and rotating shaft ends 5 are arranged on both sides of the fulcrum, and can be rotatably installed on the corresponding shaft end fixing openings 6 in the housing 1; a reset member is arranged on the lever 4, and the reset member is a spring or a torsion spring 7 (a torsion spring is used in this embodiment), and the resistance value sensing element comprises a light pair tube composed of a photosensitive element 301 and a light-emitting element 302 and a corresponding shading portion 303, the middle section of the lever 4 directly serves as the shading portion 303, and the photosensitive element 301 and the light-emitting element 302 are located on both sides of the shading portion 303.

[0028] When working, the light-emitting element 302 emits light to the photosensitive element 301. When the lever 4 is acted upon by an external force, it swings between the light-emitting element 302 and the photosensitive element 301, that is, the light shielding portion 303 shields the light, thereby changing the amount of light received by the photosensitive element 301, and then obtaining different resistance values. A photoresistor is a component whose resistance value changes with the intensity (brightness) of external light. The stronger the light, the smaller the resistance value, and the weaker the light, the larger the resistance value.

[0029] Example 2: Figure 3 As shown, a lever type potentiometer comprises a shell 1, a PCB board 2 is arranged in the shell 1, the PCB board 2 is provided with a pin 201, a resistance value sensing element is arranged on the PCB board 2, a vertically swinging lever 4 is arranged in the shell 1, one end of the lever 4 extends to the outside of the shell 1 to form a swinging driving end, the fulcrum of the lever 4 is arranged at the inner end of the lever 4, and rotating shaft ends 5 are arranged on both sides of the fulcrum, and can be rotatably installed on the corresponding shaft end fixing openings 6 in the shell 1; a reset member is arranged on the lever 4, and the reset member is a spring or a torsion spring 7 (a torsion spring 7 is used in this embodiment), and the resistance value sensing element comprises an infrared transmitting and receiving integrated tube 304 and a reflecting surface 305, and the reflecting surface 305 is arranged on the lever 4 and is arranged opposite to the infrared transmitting and receiving integrated tube 304.

[0030] During operation, the infrared transmitting and receiving integrated tube 304 emits light. When the lever 4 is acted upon by an external force, it swings to the light emitted by the infrared transmitting and receiving integrated tube 304, and reflects the light to the light receiving area of ​​the infrared transmitting and receiving integrated tube 304, thereby changing the amount of light received and obtaining different resistance values.

[0031] Example 3: Figure 4 As shown, a lever type potentiometer comprises a shell 1, a PCB board 2 is arranged in the shell 1, the PCB board 2 is provided with a pin 201, a resistance value sensing element is arranged on the PCB board 2, a vertical swing lever 4 is arranged in the shell 1, one end of the lever 4 extends to the outside of the shell 1 to form a swinging drive end, the fulcrum of the lever 4 is arranged in the middle of the lever 4, and rotating shaft ends 5 are arranged on both sides of the fulcrum, and can be rotatably installed on the corresponding shaft end fixing openings 6 in the shell 1; a reset member is arranged on the lever 4, and the reset member is a spring or a torsion spring 7 (a torsion spring 7 is used in this embodiment); the resistance value sensing element comprises a Hall sensor 306 and a magnet 307, and the magnet 307 is fixed to one end of the inner side of the lever 4.

[0032] During operation, when the lever 4 is acted upon by an external force, the magnet 307 is driven by the lever 4 to gradually approach the Hall sensor 306, and the Hall sensor 306 senses the change in the strength of the magnet 307, thereby obtaining different resistance values. The closer the distance between the magnet 307 and the Hall sensor 306, the stronger the magnetic field, the greater the resistance value, and vice versa.

[0033] Example 4: Figure 5 As shown, a lever type potentiometer comprises a housing 1, a PCB board 2 is arranged in the housing 1, the PCB board 2 is provided with a pin 201, a resistance value sensing element is arranged on the PCB board 2, a horizontally swinging lever 4 is arranged in the housing 1, the fulcrum of the lever 4 is arranged in the middle of the lever 4, rotating shaft ends 5 are arranged on both sides of the fulcrum, and are rotatably mounted on corresponding shaft end fixing openings 6 in the housing 1, one end of the lever 4 extends to the outside of the housing 1 to form a swinging driving end, a reset member is arranged on the lever 4, and the reset member is a spring or a torsion spring 7 (a torsion spring 7 is used in this embodiment), the resistance value sensing element comprises a light pair tube composed of a photosensitive element 301 and a light-emitting element 302 and a corresponding shading portion 303, one inner end of the lever 4 directly serves as the shading portion 303, and the photosensitive element 301 and the light-emitting element 302 are located on both sides of the shading portion 303.

[0034] When working, the light emitting element 302 emits light to the photosensitive element 301. When the lever 4 is acted upon by an external force, it drives the end shading portion 303 to move in an arc, causing the amount of light passing through the end edge of the shading portion 303 to change, thereby changing the amount of light received by the photosensitive element 301, and then obtaining a different resistance value.

[0035] Example 5: Figure 6 , Figure 7 As shown, based on any of the above embodiments, the rotating shaft ends 5 on both sides of the fulcrum extend out of the housing 1 (such as Figure 8 , Fig. 9 As shown, only one side of the rotating shaft end 5 extends out of the housing 1), and forms a spare rotating drive end 8, which can be used to connect with the knob and be used as a knob switch, thereby increasing the function of the utility model as a rotating shaft potentiometer.

[0036] The lever 4 of the utility model is directly connected to the lever, and can be used as a lever switch. At the same time, it can also be directly used in conjunction with a trigger button or an ordinary button, that is, when the trigger button or the ordinary button is pressed down, it directly presses the outer end of the lever 4 of the utility model. Of course, if it is necessary to establish a connection with the trigger button 9 or the ordinary button, as shown in FIG. Fig.10 , Fig.11 As shown, a strip hole 10 is required to be provided at one end of the outer side of the lever 4, and the strip hole 10 is slidably connected to the driving end 11 provided with the trigger button 9 or the ordinary button. When one end of the trigger button 9 is pressed down, it slides in the strip hole 10 and presses down the lever 4. Conversely, it is also possible to set the strip hole 10 to the driving end 11 of the trigger button 9 or the ordinary button, and accordingly, a sliding end is provided at one end of the outer side of the lever 4 to cooperate with the strip hole 10. It can be seen that even when the utility model is used in conjunction with a trigger button, it is not necessary to use a connecting rod mechanism to realize the action of pressing the button to press the potentiometer like when the trigger button is used in conjunction with a button potentiometer.
