Description

Technical Field

[0001] The utility model belongs to the field of remote controllers, in particular to a remote controller. Background Art

[0002] The working principle of the currently known remote control is that when the user operates a certain button on the remote control, a corresponding electrical signal will be generated. After the remote control encodes and amplifies the signal, it will then emit a light wave (infrared) through the transmitting diode on the remote control to transmit the signal. When the infrared receiving device of the controlled device receives the infrared signal, it will convert the infrared signal into an electrical signal; then decode the electrical signal and demodulate the corresponding command to control the controlled device. Since the communication medium between the currently known infrared remote control and the controlled device is infrared, its frequency is about 330THz and its wavelength is very short, about 900nm, so its diffraction ability to obstacles is poor; therefore, when using it, the infrared emitting device on the remote control must be aligned with the infrared receiving device on the controlled device. If there is an opaque obstacle blocking the two, or the angle of deviation is large, the transmission of infrared will be seriously blocked, making the operable distance of the remote control very short, or even completely ineffective.

[0003] There are the following problems:

[0004] 1. The infrared remote control has poor diffraction ability against obstacles;

[0005] 2. The existing remote control is not convenient to operate and its appearance is not beautiful enough. Utility Model Content

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] Please refer to Figure 1-10 PCBA generally refers to a processing flow, which can also be understood as a finished circuit board. That is, PCBA can only be considered after all the processes on the PCB board are completed. PCB refers to an empty printed circuit board with no parts on it. The PCBA in this utility model refers to a finished circuit board.

[0040] like Figure 1, Figure 2 , Figure 3 , Figure 4 As shown, the utility model provides a remote controller, including: a lower cover 1, a PCBA 2 is provided on the upper side of the lower cover 1, a ring-shaped volume potentiometer 3 is fixed on the PCBA 2, one side of the outer diameter of the volume potentiometer 3 can be clamped with a ring knob 4, a bayonet 31 and a limit groove 32 are provided on one side of the outer diameter of the volume potentiometer 3, and a clamping block 41 and a limit block 42 are provided on one side of the inner diameter of the ring knob 4. When the hollow area of ​​the ring knob 4 is aligned with the volume potentiometer 3 and moved downward, the clamping block 41 can enter the bayonet 31, and the limit groove 32 can support the limit block 42, so that the ring knob 4 stops moving downward. By rotating the ring knob 4, the volume potentiometer 3 can be controlled to send an input signal to the PCBA 2, and then the PCBA 2 sends a corresponding output command signal according to the input signal, and the output command signal sent is a Bluetooth signal. A ring-shaped groove 43 is provided on one side of the outer diameter of the ring knob 4, and the groove 43 can be sleeved with a rubber ring 44. The device is a circular remote controller, which is different from a traditional rectangular remote controller, and the buttons of the remote controller are arranged closely, reducing unnecessary space waste. A bayonet 31 is provided on one side of the outer diameter of the volume potentiometer 3 of the device, and a clamping block 41 is provided on one side of the inner diameter of the annular knob 4. The clamping block 41 can be clamped into the bayonet 31, so that the annular knob 4 can be prevented from being easily pulled out from the volume potentiometer 3; a limiting groove 32 is provided on one side of the outer diameter of the volume potentiometer 3, and a limiting block 42 is provided on one side of the inner diameter of the annular knob 4. The limiting groove 32 can support the limiting block 42. The cooperation between the limiting groove 32 and the limiting block 42 can constrain the annular knob 4, prevent the annular knob 4 from endlessly moving downward relative to the volume potentiometer 3, and also prevent the annular knob 4 from rotating on the volume potentiometer 3. By rotating the annular knob 4 connected to the volume potentiometer 3, the volume potentiometer 3 can be controlled to send an input signal to the PCBA2. The PCBA2 that receives the input signal sends a corresponding output command signal according to the input signal. The output command signal here is a Bluetooth signal. Since the communication medium of the Bluetooth transmission method is an electromagnetic wave of about 2.4GHz, its wavelength is about 0.125m, and the communication medium of the infrared transmission method is infrared of about 330THz, its wavelength is about 900nm, it can be seen that the wavelength of Bluetooth transmission is much larger than that of infrared. Therefore, the Bluetooth transmission method is easier to bypass obstacles for transmission, and is not limited by the communication angle and direction, thereby solving the problem that the traditional infrared remote control is easily blocked by obstacles and the transmission is blocked when the angle offset is large, resulting in a shorter operating distance. In order to make the operating feel of the annular knob 4 better, a non-slip silicone rubber ring 44 is also sleeved on the groove 42 of its outer diameter. Since the inner diameter of the rubber ring 44 is slightly smaller than the outer diameter of the annular groove 42, the rubber ring 44 can be sleeved on the annular knob 4 without sliding easily. Moreover, when the user operates the knob, the fingers holding the rubber ring 44 will not slip.

[0041] like Figure 5 As shown, a plurality of micro switches 21 and an annular support plate B5 are provided in the hollow area corresponding to the annular volume potentiometer 3 on the PCBA2, and a support column 51 and a push column 52 are provided on one side of the support plate B5. The support column 51 is connected to the PCBA, and the push column 52 can contact the micro switch 21. The support column 51 can be connected and fixed to the PCBA2. The support column 51 in this embodiment is connected to the PCBA2 by screw locking, which can play a fixing role. The push column 52 can contact the micro switch 21. When force is transmitted to the push column 52, the push column 52 can continue to transmit the force to the micro switch 21. The reason why the micro switch 21 is set in the hollow area of ​​the annular volume potentiometer 3 is to allow the support column 51 and the push column 52 of the support plate B5 to avoid the volume potentiometer 3.

[0042] like Figure 6 As shown, a micro switch 22 and a circular support plate A6 are provided in the hollow area corresponding to the support plate B5 on the PCBA2, and a support column 2 61 and a push column 2 62 are provided on one side of the support plate A6. The support column 2 61 is connected to the PCBA2, and the push column 2 62 can contact the micro switch 2 22. The support column 2 61 in this embodiment is connected to the PCBA2 by screw locking, which can play a fixing role. The push column 2 61 can contact the micro switch 2 22. When force is transmitted to the push column 2 22, the push column 2 22 can continue to transmit force to the micro switch 2 22. The reason why the micro switch 2 22 is set in the hollow area of ​​the support plate B5 is to enable the support column 2 61 and the push column 2 62 of the support plate B5 to avoid the support plate B5. The micro switch 1 21 and the micro switch 2 22 can send an input signal to the PCBA2, and then the PCBA2 sends a corresponding output command signal according to the input signal. The output command signal sent is a Bluetooth signal. The output command signals sent by this device are all Bluetooth signals, which can cope with the command signal transmission in more complex environments and conditions.

[0043] like Figure 7As shown, a padding block 53 is provided on the opposite side of the pressing column 52 on the support plate B5, and a fixing column 531 is provided on the padding block 53. The padding block 53 can pad the support plate A6, and the support plate A6 is provided with a fixing hole 63 that can cooperate with the fixing column 531, and the fixing column 531 can be scalded by an electric soldering iron. Padding the support plate A6 by the padding block 53 can effectively reduce the contact area between the support plate B5 and the support plate A6, because both the support plate B5 and the support plate A6 have a certain elasticity, the padding block 53 can better transmit force and reduce the loss of force. If B5 and the support plate A6 are in a state of being attached together, when the support plate A6 is deformed, the support plate B5 will also be greatly deformed. After the fixing column 531 passes through the fixing hole 63, the part of the fixing column 531 that passes through the fixing hole 63 can be scalded by an electric soldering iron, so that the connecting parts can be saved, and the support plate A6 can be installed on the support plate B5 conveniently and quickly.

[0044] like Figure 8 As shown, the support plate A6 includes an inner ring plate 64 and an outer ring plate 65, and the inner ring plate 64 and the outer ring plate 65 are connected by an elastic plate 641. When the inner ring plate 64 is pressed, the micro switch 1 21 will not send an input signal to PCBA2; when the outer ring plate 65 is pressed, the micro switch 2 22 will not send an input signal to PCBA2. The separation of the outer ring plate 65 and the inner ring plate 64 can effectively distinguish the triggering of the micro switch 1 21 and the micro switch 2 22. The inner ring plate 64 is connected to the outer ring plate 65 by the elastic plate 641, which can effectively fix the relative position of the inner ring plate 64 and prevent the inner ring plate 64 from shaking.

[0045] like Fig. 9 As shown, a button 7 is provided on the side of the inner ring plate 64 away from the supporting column 2 61, and a flange 71 is provided on the side of the button 7 close to the inner ring plate 64. An annular button 2 8 is provided on the side of the outer ring plate 65 away from the supporting column 2 61, and a flange 2 81 is provided on the inner ring of the button 2 8. The button 1 7 can be fully exposed from the annular inner ring provided with the flange 2 81, and the flange 1 71 can abut against the flange 2 81 to prevent the button 1 7 from passing through the button 2 8. The button 2 8 can be connected with the outer ring plate 6, and the flange 2 81 is provided on the inner ring of the button 2 8, and the flange 1 71 is provided. The flange 1 71 abuts against the flange 2 81 to prevent the button 1 7 from passing through the annular hole of the annular button 2 8. At the same time, the side of the button 1 7 close to the inner ring plate 64 can also be connected by a column and a hole, and then the column is scalded to strengthen the fixing of the button 1 7 again.

[0046] like Fig.10As shown, the button 1 7 and the button 2 8 are sprayed with black paint, the side of the button 1 7 away from the support plate A6 is silk-screened with white symbols indicating the button function, and the area of ​​the button 2 8 away from the support plate A6 corresponding to the micro switch 1 21 is silk-screened with white symbols indicating the button function, and each white symbol area can be used as an independent function button. The surface of the annular knob 4 is electroplated with a layer of bright silver chromium metal. The side of the annular knob 4 away from the volume potentiometer 3 is provided with concentric concave textures, which can produce a silvery and shining visual effect.

[0047] PCBA2 also includes a Bluetooth chip, MIC, and positive and negative battery contacts. The entire PCBA2 is fixed to the lower cover 1 by screws. A button battery is installed in the battery compartment between PCBA2 and the lower cover 1. The battery compartment includes a snap-on battery cover iron sheet to prevent the button battery from falling. A base 9 is provided below the lower cover 1. A magnet is embedded in the base 9 during the injection molding stage so that it can be attracted to the battery cover iron sheet in the lower cover 1, so that the device can be magnetically attracted to the base 9. A round strong double-sided adhesive is adhered to the bottom surface of the base 9 so that the base 9 can be adhered to a suitable surface of an object, such as the surface of the controlled device or the wall, so that the user can store the device.
