Description

Technical Field

[0001] This invention relates to the field of smart home technology, and in particular to a remote control system and charging dock, and a remote control. Background Technology

[0002] Currently, smart TVs are typically controlled using a remote control. Traditional remote controls usually have a built-in lithium battery that powers the remote.

[0003] With the development of solar power generation materials, solar panels can be installed on remote controls to convert ambient light into electrical energy to power the remote control, thus eliminating the need for lithium batteries in the remote control and facilitating its miniaturization.

[0004] However, due to the typically small size of remote controls, it's difficult to mount a large solar panel on them, limiting their charging power. In practical use, this often results in the remote running out of power and becoming unresponsive, leading to a poor user experience. Summary of the Invention

[0005] The purpose of this invention is at least to provide a remote control system, a charging base, and a remote control that can quickly charge the remote control while miniaturizing it, thereby improving the user experience.

[0006] In a first aspect, the present invention provides a remote control system, comprising: a remote control and a charging base, wherein: the charging base includes a power generation board, a first energy storage capacitor, a voltage management circuit, and a discharge contact; wherein: the power generation board is disposed on the outer surface of the charging base and is adapted to convert ambient light into electrical energy; the voltage management circuit is disposed between the power generation board and the first energy storage capacitor, and processes the electrical energy generated by the power generation board and outputs it to the first energy storage capacitor; the first energy storage capacitor is connected to the discharge contact and stores the input electrical energy; the remote control includes a charging contact, a second energy storage capacitor, and a main control module, wherein: the second energy storage capacitor is connected to the charging contact, and the main control module is connected to the second energy storage capacitor; when the charging contact is connected to the discharge contact, the first energy storage capacitor charges the second energy storage capacitor; the second energy storage capacitor is adapted to supply power to the main control module.

[0007] A power generation plate is mounted on the outer surface of the charging base, converting ambient light into electrical energy. The charging base includes discharge contacts, and the remote control includes charging contacts. When the discharge contacts of the charging base are physically connected to the charging contacts of the remote control, the charging base supplies power to the remote control. The remote control contains a second energy storage capacitor to store the electrical energy output from the charging base, which then powers the main control module. Due to the relatively large area of ​​the charging base, it has a large light-receiving area, thus allowing it to store a significant amount of electrical energy. The connection between the discharge and charging contacts enables rapid charging of the second energy storage capacitor. Therefore, there is no need to include a lithium battery in the remote control, achieving miniaturization while rapidly replenishing its power, thus improving the user experience.

[0008] Optionally, the voltage management circuit is adapted to disconnect the charging path between the power generation panel and the first energy storage capacitor when it detects that the voltage of the first energy storage capacitor has reached a preset upper limit voltage.

[0009] Optionally, the charging base further includes a charging control circuit, disposed between the first energy storage capacitor and the discharge contact, adapted to control the current flowing through the discharge contact to not exceed a preset current threshold when the discharge contact is connected to the charging contact.

[0010] Optionally, the remote controller further includes: a DC-to-DC voltage regulator, disposed between the second energy storage capacitor and the main control module, which takes the output voltage of the second energy storage capacitor as input, regulates the output voltage of the second energy storage capacitor, and outputs the regulated voltage to the main control module.

[0011] Optionally, the first energy storage capacitor is a first supercapacitor, the second energy storage capacitor is a second supercapacitor, and the capacitance of the first supercapacitor is not less than the capacitance of the second supercapacitor.

[0012] Both the first and second energy storage capacitors are supercapacitors. When the first energy storage capacitor charges the second energy storage capacitor, since both are supercapacitors and the second energy storage capacitor has a smaller capacitance, the charging speed of the second energy storage capacitor is faster. This allows the remote control to work normally without the user having to wait for a long time, thus improving the user experience.

[0013] Furthermore, since both the first and second energy storage capacitors are supercapacitors, and supercapacitors have a wider operating temperature range, the risk of thermal runaway is effectively avoided, resulting in higher safety for the remote control. Moreover, compared to lithium batteries, supercapacitors have a greater number of charge-discharge cycles and do not suffer from chemical aging, significantly extending the lifespan of the remote control.

[0014] Secondly, the present invention provides a charging base, comprising: a power generation plate, a first energy storage capacitor, a voltage management circuit, and a discharge contact, wherein: the power generation plate is disposed on the outer surface of the charging base and connected to the voltage management circuit, and is adapted to convert ambient light into electrical energy and output it; the voltage management circuit is connected to the first energy storage capacitor, processes the electrical energy output by the power generation plate, and outputs the processed electrical energy to the first energy storage capacitor; the first energy storage capacitor is connected to the discharge contact and is used to store input electrical energy.

[0015] Optionally, the voltage management circuit is adapted to disconnect the charging path between the power generation panel and the first energy storage capacitor when it detects that the voltage of the first energy storage capacitor has reached a preset upper limit voltage.

[0016] Optionally, the charging base further includes a charging control circuit, disposed between the first energy storage capacitor and the discharge contact, adapted to control the current flowing through the discharge contact to not exceed a preset current threshold when the discharge contact is connected to the charging contact.

[0017] Thirdly, the present invention also provides a remote control, comprising: a charging contact, a second energy storage capacitor, and a main control module, wherein: the charging contact, when connected with the discharge contact of the charging base, outputs electrical energy to the second energy storage capacitor; the second energy storage capacitor is connected to the main control module and is adapted to supply power to the main control module.

[0018] Optionally, the remote controller further includes: a DC-to-DC voltage regulator, disposed between the second energy storage capacitor and the main control module, which takes the output voltage of the second energy storage capacitor as input, regulates the output voltage of the second energy storage capacitor, and outputs the regulated voltage to the main control module.

Detailed Implementation

[0020] As described in the background section, when installing a solar panel on a remote control, the small light-receiving area of ​​the remote control makes it difficult to install a large-area solar panel. Therefore, the electrical energy provided by the solar panel is limited. Furthermore, because users may place the remote control with the light-receiving side of the solar panel facing downwards, the charging power of the remote control is significantly limited. When the remote control's battery is low, it cannot respond to user operations, and the user needs to adjust the orientation of the light-receiving side of the solar panel on the remote control, resulting in a poor user experience.

[0021] In this embodiment of the invention, when the discharge contact of the charging base is physically connected to the charging contact of the remote control, the charging base supplies power to the remote control. The remote control contains a second energy storage capacitor that stores the electrical energy output from the charging base, thereby supplying power to the main control module. Because the charging base has a relatively large area and a large light-receiving area, it can store a significant amount of electrical energy. The connection between the discharge and charging contacts allows for rapid charging of the second energy storage capacitor. Therefore, there is no need to include a lithium battery in the remote control, achieving miniaturization while quickly replenishing its power, thus improving the user experience.

[0022] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] This invention provides a remote control system, referring to... Figure 1 . Reference Figure 2 A schematic diagram of the structure of a remote control according to an embodiment of the present invention is provided. (Refer to...) Figure 3 A schematic diagram of a charging dock according to an embodiment of the present invention is provided. (Refer to...) Figure 4 A schematic diagram of a charging dock according to an embodiment of the present invention is provided. The following is in conjunction with... Figures 1-4 Please provide an explanation.

[0024] In this embodiment of the invention, the charging base 10 may include a power generation board 101, a first energy storage capacitor 103, a voltage management circuit 102, and a discharge contact 105.

[0025] In a specific implementation, the power generation board 101 can be disposed on the outer surface of the charging base 10. The power generation board 101 can convert ambient light into electrical energy. The power generation board 101 can be electrically connected to the voltage management circuit 102, and output the generated electrical energy to the voltage management circuit 102.

[0026] like Figure 4As shown, an opening 401 is provided on the charging base 10, and a discharge contact 105 is provided in the opening 401. When charging the remote control 20, the tail of the remote control 20 can be inserted into the opening 401 to establish an electrical connection between the charging contact 204 provided on the tail (or end) of the remote control 20 and the discharge contact 105 of the charging base 10. A generator plate 101 is provided on the outer surface of the charging base 10.

[0027] The power generation plate 101 can be disposed in one or more areas on the outer surface of the charging base 10. For example... Figure 4 As shown, two power generation plates 101 are respectively provided in two areas on the outer surface of the charging base 10, and the opening 401 is provided between the two power generation plates.

[0028] It is understandable that the power generation plate 101 may also be provided only in a certain area of ​​the outer surface of the charging base 10. For example, on the outer surface of the charging base 10, only one power generation plate 101 may be provided above the opening 401. The number and placement of the power generation plates 101 can be set according to the specific application scenario and actual needs.

[0029] The voltage management circuit 102 can manage the voltage of the electrical energy output by the power generation board 101. The output terminal of the voltage management circuit 102 can be electrically connected to the first energy storage capacitor 103 to output the voltage-managed electrical energy to the first energy storage capacitor 103.

[0030] The first energy storage capacitor 103 can store the input electrical energy. The first energy storage capacitor 103 can be electrically connected to the discharge contact 105. When the charging contact 204 of the remote control 20 contacts the discharge contact 105 of the charging base 10, the first energy storage capacitor 103 can output the stored electrical energy to the remote control 20 through the discharge contact 105.

[0031] In specific implementations, the power generation panel 101 can be a low-light power generation panel 101, which can generate and output electrical energy under low light intensity (e.g., illuminance of several hundred lux).

[0032] In some embodiments, the power generation panel 101 may be a perovskite solar panel, or other types of panels capable of generating and outputting a stable current under low light intensity.

[0033] In a specific implementation, the voltage management circuit 102 can convert the electrical energy output by the power generation board 101 to perform voltage regulation on the electrical energy output by the power generation board 101.

[0034] In some embodiments, the voltage management circuit 102 can boost or buck the electrical energy output from the power generation panel 101. Specifically, a rated voltage threshold corresponding to the voltage management circuit 102 can be preset, and the output voltage of the voltage management circuit 102 can be equal to this rated voltage threshold. The rated voltage threshold can be associated with the rated operating voltage of the first energy storage capacitor 103.

[0035] When the output voltage of the generator board 101 is greater than the rated voltage threshold, the voltage management circuit 102 can step down the output voltage; when the output voltage of the generator board 101 is less than the rated voltage threshold, the voltage management circuit 102 can boost the output voltage.

[0036] In practical implementation, the first energy storage capacitor 103 can be a supercapacitor. Supercapacitors have a large capacitance, typically greater than 1 farad (F). They can quickly absorb the weak and unstable current generated by the power generation plate 101, supporting over a million charge-discharge cycles. Furthermore, supercapacitors have a wide operating temperature range (-40℃ to +65℃). Supercapacitors can also be called electrochemical double-layer capacitors (EDLCs), including carbon electrode double-layer supercapacitors, metal oxide electrode supercapacitors, and organic polymer electrode supercapacitors.

[0037] Therefore, the charging base 10 provided in this embodiment of the invention can generate continuous electrical energy in a low-light environment to charge the first energy storage capacitor 103.

[0038] When the voltage of the first energy storage capacitor 103 has not reached the upper limit voltage, it can continue to be charged by the generator board 101. When the voltage management circuit 102 detects that the voltage of the first energy storage capacitor 103 has reached the upper limit, it means that the first energy storage capacitor 103 is fully charged. The voltage management circuit 102 can cut off the charging path between the first energy storage capacitor 103 and the generator board 101 to avoid overcharging of the first energy storage capacitor 103.

[0039] In this embodiment of the invention, the remote controller 20 may include a charging contact 204, a second energy storage capacitor 203, and a main control circuit 201. The second energy storage capacitor 203 is connected to the charging contact 204, and the main control circuit 201 is connected to the second energy storage capacitor 203. When the charging contact 204 in the remote controller 20 establishes a physical connection with the discharge contact 105 of the charging base 10, a charging path is formed between the first energy storage capacitor 103 and the second energy storage capacitor 203, and the first energy storage capacitor 103 outputs electrical energy to the second energy storage capacitor 203. The second energy storage capacitor 203 receives and stores the electrical energy output by the first energy storage capacitor 103. The second energy storage capacitor 203 can supply power to the main control circuit 201.

[0040] In practical implementation, the aforementioned main control circuit 201 can be a module capable of implementing the control functions of the remote control 20. For example, the user can interact with the main control circuit 201 through the button module 205 on the remote control 20 to achieve functions such as volume control, channel switching, and program selection.

[0041] In a specific implementation, the charging contact 204 can be located at the tail of the remote control 20. When the remote control 20 needs to be charged, the user can insert the tail of the remote control 20 into the opening of the charging base 10 to establish a physical connection between the charging contact 204 and the discharging contact 105. Thus, the first energy storage capacitor 103 establishes a connection path with the second energy storage capacitor 203 through the discharging contact 105 and the charging contact 204.

[0042] The second energy storage capacitor 203 can also be a supercapacitor. The capacitance of the second energy storage capacitor 203 can be smaller than the capacitance of the first energy storage capacitor 103. In some embodiments, the capacitance of the second energy storage capacitor 203 can be between 1F and 10F.

[0043] It is understandable that the capacitance of the second energy storage capacitor 203 can also be other values, and can be set based on specific application scenarios and actual needs. For example, the second energy storage capacitor 203 with an appropriate capacitance can be selected based on the standby time requirements of the remote control 20 and cost.

[0044] The voltage of the first energy storage capacitor 103 is higher than the voltage of the second energy storage capacitor 203, and the charge of the first energy storage capacitor is also higher than the charge of the second energy storage capacitor 203. Therefore, when the first energy storage capacitor 103 and the second energy storage capacitor 203 establish a connection path, the first energy storage capacitor 103 outputs electrical energy to the second energy storage capacitor 203.

[0045] In a specific implementation, a charging control circuit 104 can be provided between the first energy storage capacitor 103 and the discharge contact 105 in the charging base 10. When the discharge contact 105 of the charging base 10 is connected to the charging contact 204 of the remote control 20, during the process of the first energy storage capacitor 103 outputting electrical energy to the second energy storage capacitor 203, the charging control circuit 104 controls the current of the discharge contact 105 to not exceed a preset current threshold. This avoids damage to the second energy storage capacitor 203 due to a large discharge current output by the first energy storage capacitor 103.

[0046] Once the charging contact 204 and the discharging contact 105 are physically connected, the first energy storage capacitor 103 can quickly output electrical energy to the second energy storage capacitor 203. The second energy storage capacitor 203 can be fully charged within tens of seconds to a few minutes.

[0047] In a specific implementation, the remote controller 20 may further include a DC-DC converter 202, which is positioned between the second energy storage capacitor 203 and the main control circuit 201. The input terminal of the DC-DC converter 202 is connected to the second energy storage capacitor 203, receiving the output voltage of the second energy storage capacitor 203 as input; the output terminal of the DC-DC converter 202 is connected to the power supply terminal of the main control circuit 201, and after regulating the output voltage of the second energy storage capacitor 203, it is output to the main control circuit 201 to power the main control circuit 201.

[0048] By setting up the DC-DC regulator 202, it can be ensured that the second energy storage capacitor 203 can provide a stable output voltage during the power supply process of the main control circuit 201. Even if the output voltage of the second energy storage capacitor 203 drops, the DC-DC regulator 202 can still provide a stable output voltage to the main control circuit 201.

[0049] In practical applications, the remote control 20 is in standby mode when not in use. In standby mode, the power consumption of the remote control 20 is extremely low, with a standby current in the microamp level.

[0050] The electrical energy stored in the second energy storage capacitor 203 can keep the remote control 20 in standby mode for a long time, which can last for several weeks or even longer. The duration of standby mode for the remote control 20 is related to the capacitance stored in the second energy storage capacitor 203. The larger the capacitance stored in the second energy storage capacitor 203, the longer the corresponding standby mode duration for the remote control 20.

[0051] When a user uses the remote control 20, they can press the button module 206, such as the volume control button or the number keys. When the user presses the button module 206, the main control circuit 201 and the wireless communication module 205 in the remote control 20 are activated, providing a large current pulse through the second energy storage capacitor 203. When the remote control 20 is in working condition, the aforementioned current pulse is a milliampere-level current pulse.

[0052] In practical applications, the aforementioned wireless communication module 205 can be a Bluetooth communication module or a WIFI communication module, or other communication modules capable of wireless communication functions.

[0053] Because the second energy storage capacitor 203 is a supercapacitor, it can easily provide short-duration, high-power pulses. Compared to traditional lithium batteries, the second energy storage capacitor 203 does not experience a voltage drop due to its higher internal resistance.

[0054] The working process of the remote control system provided in the above embodiments of the present invention will be described below.

[0055] The charging dock can typically be placed in a fixed location, such as on a coffee table in the living room, on the surface of a TV cabinet, or in other locations. A power generation plate on the outer surface of the charging dock can detect ambient light and convert it into electrical energy, which is then stored in a primary energy storage capacitor.

[0056] When the user is not using the remote control, the user can insert the end of the remote control into the opening of the charging dock. After the end of the remote control is inserted into the opening of the charging dock, the first energy storage capacitor in the charging dock charges the second energy storage capacitor in the remote control.

[0057] When using the remote control, the user can pull it out from the opening on the charging dock to operate it. This ensures that the remote control is always fully charged before use.

[0058] Even if the user does not insert the tail of the remote control into the opening of the charging base after use, the second energy storage capacitor can still keep the remote control in standby mode for a long time.

[0059] In summary, the remote control system provided in this embodiment of the invention supplies power to the remote control when the discharge contact of the charging base is physically connected to the charging contact of the remote control. The remote control contains a second energy storage capacitor to store the electrical energy output from the charging base, which then powers the main control module. Because the charging base has a relatively large area and a large light-receiving area, it can store a significant amount of electrical energy. The connection between the discharge and charging contacts allows for rapid charging of the second energy storage capacitor. Therefore, there is no need to include a lithium battery in the remote control, achieving miniaturization while quickly replenishing its power, thus improving the user experience.

[0060] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
