Description

Technical Field

[0001] This utility model relates to the field of remote control technology, specifically to a solar-powered remote control. Background Technology

[0002] In daily life, various household appliances such as televisions, stereos, and air conditioners all require remote controls. Traditional remote controls mostly use dry cell batteries, alkaline batteries, or mercury batteries as their power source. These batteries not only require regular replacement, causing inconvenience, but also suffer from leakage problems that can damage the remote control itself. Furthermore, the used batteries from traditional remote controls can easily cause serious environmental pollution. Therefore, solar-powered remote controls have become a key research focus.

[0003] In existing solar-powered remote controls, there are often no opaque coverings on the surface of the solar panel. Specifically, there are two main structures: one is to use a completely opaque outer shell (for example, by adding dyes such as carbon to make the shell opaque), with the solar panel placed on the surface of the shell. This approach affects the aesthetics of the remote control, and the exposed solar panel is more susceptible to damage. The other approach is to use a transparent outer shell to encapsulate the solar panel inside the shell. However, the transparent shell exposes the internal structure of the remote control, which also affects the product's aesthetics.

[0004] Furthermore, regardless of whether a solar-powered remote control uses a transparent or opaque casing, the button layer is typically made of rubber and an opaque dye (e.g., black dye). Therefore, to ensure the solar panel can absorb sunlight, the button layer cannot cover the solar panel surface. Given the limited size of the remote control itself, the button layer occupies a portion of the space, forcing the solar panel to be smaller, thus limiting power generation. Utility Model Content

[0005] The technical problem solved by this utility model embodiment is how to maximize the power generation of the solar panel while keeping the size of the remote control limited and without affecting the aesthetics of the remote control.

[0006] To address the aforementioned technical problems, this utility model provides a solar-powered remote control, comprising the following steps: an opaque first outer shell layer, which transmits light within a target wavelength range; a button layer fixed to the first outer shell layer, which transmits at least a portion of the light transmitted through the first outer shell layer; a first solar panel located below the button layer, wherein the wavelength range of light absorbed by the first solar panel is within the target wavelength range; and a circuit board located below the first solar panel; wherein the first solar panel absorbs light transmitted through the first outer shell layer and the button layer and converts it into electrical energy, which is then transmitted to the circuit board to power the solar-powered remote control.

[0007] Optionally, the solar-powered remote controller further includes a second solar panel and an opaque second outer shell layer, the second solar panel being located between the circuit board and the second outer shell layer; the second outer shell layer is transparent to light within the target wavelength range, and the wavelength range of light that the second solar panel can absorb is within the target wavelength range; wherein, the second solar panel absorbs the light transmitted from the second outer shell layer and converts it into electrical energy, which is then transmitted to the circuit board to power the solar-powered remote controller.

[0008] Optionally, the second solar panel is a bifacial solar panel, with the second side of the second solar panel facing the second side of the circuit board; the second side of the circuit board is coated with a reflective material to reflect light transmitted from the second outer shell layer and the second solar panel to the second side of the second solar panel, so that the second side of the second solar panel absorbs the reflected light and converts it into electrical energy, which is then transmitted to the circuit board.

[0009] Optionally, the first solar panel is a bifacial solar panel, with the second side of the first solar panel facing the first side of the circuit board; the first side of the circuit board is coated with a reflective material to reflect light transmitted from the first outer shell layer, the button layer and the first solar panel to the second side of the first solar panel, so that the second side of the first solar panel absorbs the reflected light and converts it into electrical energy, which is then transmitted to the circuit board.

[0010] Optionally, the reflective material includes reflective ink.

[0011] Optionally, the first outer shell layer has multiple through holes, and the first surface of the button layer has multiple buttons, each of which corresponds to one of the multiple through holes, with each button passing through the corresponding through hole.

[0012] Optionally, the function markings on the buttons of the button layer are formed using a screen printing process.

[0013] Optionally, the key layer is made of transparent rubber, and the transparent rubber contains diffusion powder.

[0014] Optionally, the target wavelength range includes one or more of the following: 600nm~800nm, 300nm~500nm.

[0015] Optionally, the first outer shell layer is dyed using a dyeing material that can transmit light within the target wavelength range.

[0016] Optionally, the material forming the first outer shell layer includes: a thermoplastic polymer material and a diffusion powder.

[0017] Compared with the prior art, the technical solution of this utility model embodiment has the following beneficial effects:

[0018] On the one hand, compared with the existing technology that uses a transparent outer shell, this embodiment uses a first outer shell layer that is opaque and has a certain light transmittance (i.e., can transmit light in the target wavelength range), combined with a first solar panel that can absorb light in the target wavelength range. This allows the first outer shell layer to play a protective role for the device, transmit sunlight of a specific wavelength and be effectively absorbed by the solar panel, without affecting the aesthetics of the remote control.

[0019] On the other hand, compared to existing technologies that use a completely opaque button layer without covering the solar panel, this implementation scheme allows the button layer to be translucent, and places the solar panel below the button layer, meaning the button layer and solar panel can overlap vertically. Therefore, given the limited size of the remote control, the solar panel can be made as large as possible (e.g., close to the size of the remote control). In low-light indoor environments, this effectively increases the power generation of the solar panel, ensuring sufficient power for the remote control and improving the user experience.

[0020] Furthermore, by using a bifacial solar panel as the first solar panel and combining it with a circuit board coated with reflective material, it is possible to maximize the size of the solar panel while ensuring that both sides of the first solar panel can absorb sunlight of a specific wavelength and convert it into electrical energy, thereby effectively increasing the power generation.

[0021] Furthermore, by adding diffusion powder to the button layer, the originally transparent rubber material button layer can be made opaque in appearance while retaining a certain degree of light transmittance. Combined with screen printing technology, each button can appear black or colored, thus achieving the light transmittance effect of the button layer without affecting the appearance of the remote control.

[0022] Furthermore, existing technologies typically do not consider the light transmittance and solar power generation performance of the bottom or back of a solar-powered remote control, thus often using completely opaque materials for the bottom outer shell. In contrast, this embodiment considers not only the light transmittance of the front (corresponding to the first outer shell) of the solar-powered remote control, but also the light transmittance and solar power generation performance of the bottom or back (corresponding to the second outer shell). Specifically, based on the first solar panel with bi-sided power generation, a second solar panel is added between the circuit board and the second outer shell (located at the bottom of the remote control). The second outer shell is designed to be opaque but translucent, and the wavelength range of light absorbed by the second solar panel is within the wavelength range of light that the second outer shell can transmit. Thus, the second outer shell can provide device protection, transmit specific wavelengths of sunlight which are effectively absorbed by the second solar panel, without affecting the aesthetics of the remote control.

[0023] Furthermore, the second solar panel can overlap with the circuit board and button layer in vertical space. Therefore, given the limited size of the remote control, the second solar panel can be made as large as possible (e.g., close to the size of the second outer shell layer). In low-light indoor environments, this effectively increases the power generation of the second solar panel, ensuring sufficient power for the remote control and improving the user experience. Moreover, in actual use, the solar-powered remote control can generate solar power regardless of whether it faces upwards or downwards, achieving a dual power generation effect, especially providing ample power in indoor lighting conditions.

[0024] Furthermore, by using a bifacial solar panel as the second solar panel and combining it with a circuit board coated with reflective material, it is possible to make both sides of the second solar panel absorb sunlight of a specific wavelength and convert it into electrical energy, while setting the size of the second solar panel as large as possible. Based on this, combined with the first solar panel with bifacial power generation function, the total power generation of the solar remote controller can be greatly increased.

[0028] As mentioned in the background section, in existing solar-powered remote controls, there are often no opaque coverings on the surface of the solar panel. The solar panel is either placed on the surface of an opaque and light-blocking outer casing or encapsulated inside a transparent outer casing. In addition, the button layer made of rubber and opaque dyes (which is almost light-blocking) cannot be covered on the surface of the solar panel.

[0029] Reference Figure 1 , Figure 1 This is a structural diagram of a solar-powered remote controller 10 in the prior art.

[0030] Specifically, the solar-powered remote control 10 includes a housing 101, a button layer 102, a solar panel 103, a display screen 104, and a circuit board (not shown).

[0031] The outer casing 101 includes a transparent sub-casing 1011; the button layer 102 is fixed to the outer casing 101 and includes several buttons 1021, each typically made of rubber and dyed with an opaque dye; the solar panel 103 is encapsulated inside the outer casing 101, and the transparent sub-casing 1011 covers the solar panel 103; the projection of the button layer 102 onto the bottom surface of the outer casing 101 does not overlap with the projection of the solar panel 103 onto the bottom surface of the outer casing 101. This ensures that the surface of the solar panel 103 is not covered by any opaque material, allowing it to absorb indoor light and convert it into electrical energy, which is then transmitted to the circuit board to power the solar-powered remote control 10.

[0032] However, on the one hand, because the aforementioned solar-powered remote control 10 uses a transparent sub-shell 1011, the internal components and wiring are exposed, resulting in poor aesthetics. On the other hand, given the limited size of the remote control itself, since the button layer 102 does not cover the solar panel 103, the button layer 102 needs to occupy a large area, which means the size of the solar panel must be smaller, thus limiting the power generation. Especially in indoor light environments with relatively weak sunlight, the daily power generation of the solar panel may be insufficient to meet the daily power consumption of the remote control.

[0033] To address the aforementioned technical problems, this utility model provides an improved solar-powered remote control, specifically comprising: an opaque first outer shell layer that transmits light within a target wavelength range; a button layer fixed to the first outer shell layer that transmits at least a portion of the light transmitted through the first outer shell layer; a first solar panel located below the button layer, the first solar panel absorbing light within the target wavelength range; and a circuit board located below the first solar panel; wherein the first solar panel absorbs light transmitted through the first outer shell layer and the button layer and converts it into electrical energy, which is then transmitted to the circuit board to power the solar-powered remote control.

[0034] On the one hand, compared with the existing technology that uses a transparent outer shell, this embodiment uses a first outer shell layer that is opaque and has a certain light transmittance (i.e., can transmit light in the target wavelength range), combined with a first solar panel that can absorb light in the target wavelength range. This allows the first outer shell layer to play a protective role for the device, transmit sunlight of a specific wavelength and be effectively absorbed by the solar panel, without affecting the aesthetics of the remote control.

[0035] On the other hand, compared to existing technologies that use a completely opaque button layer without covering the solar panel, this embodiment makes the button layer translucent and places the first solar panel below the button layer. This means the button layer and the first solar panel can overlap in vertical space. In other words, the projections of the first solar panel and the button layer onto the plane of the first outer shell can overlap. Therefore, given the limited size of the remote control, the size of the first solar panel can be made as large as possible (e.g., close to the size of the first outer shell). In low-light indoor environments, this effectively increases the power generation of the solar panel, ensuring sufficient power supply for the remote control and improving the user experience.

[0036] To make the above-mentioned objectives, features and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 2 , Figure 2 This is an exploded view of the structure of a solar-powered remote controller 20 in an embodiment of this utility model.

[0038] Specifically, the solar-powered remote control 20 includes: an opaque first outer shell layer 201, which is transparent to light within a target wavelength range; a button layer 202 fixed to the first outer shell layer 201, which is transparent to at least a portion of the light transmitted from the first outer shell layer 201; a first solar panel 203 located below the button layer 202, the first solar panel 203 having an absorbable light wavelength range within the target wavelength range; and a circuit board 204 located below the first solar panel 203. The first solar panel 203 absorbs light transmitted from the first outer shell layer 201 and the button layer 202 and converts it into electrical energy, which is then transmitted to the circuit board 204 to power the solar-powered remote control 20.

[0039] The solar-powered remote controller 20 may further include an opaque second outer shell layer 206, which is located below the circuit board 204. Specifically, the first outer shell layer 201 serves as the encapsulation shell layer on the front of the remote controller, and the second outer shell layer 206 serves as the encapsulation shell layer on the bottom or back of the remote controller.

[0040] In a specific implementation, the first outer shell layer 201 and the second outer shell layer 206 are dyed using a dyeing material that can transmit light within the target wavelength range.

[0041] As a non-limiting embodiment, the target wavelength range may include one or more of the following: 600nm to 800nm, 300nm to 500nm. Specifically, 600nm to 800nm ​​covers the wavelength range of red light, and 300nm to 500nm covers the wavelength range of blue light.

[0042] The materials forming the first outer shell layer 201 and the second outer shell layer 206 may include thermoplastic polymer materials and diffusion powder. Among them, the thermoplastic polymer material may be, for example, a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S) (Acrylonitrile Butadiene Styrene plastic, ABS).

[0043] Diffusing powder, also known as scattering powder, is a fine powder specifically designed to modify the path of light propagation and typically possesses a certain degree of light transmittance. The main components of diffusing powder usually include, but are not limited to, high-refractive-index microspheres or nanoparticles such as silica, polymethyl methacrylate, acrylic polymers, and fluoride glass microspheres. Diffusing powder scatters light under illumination, breaking up the originally straight-propagating light rays and dispersing them in all directions. This makes the originally concentrated light intensity more uniform, producing a softer, non-direct light effect.

[0044] In this embodiment of the invention, by dyeing the first outer shell layer 201 with a dyeing material that can transmit light within the target wavelength range and adding a diffusion powder, the material of the first outer shell layer 201 can appear opaque, making the solar remote control 20 more aesthetically pleasing; it can also achieve light transmission performance, and the diffusion powder can make the light transmitted from the first outer shell layer 201 more uniform, thereby improving the photoelectric conversion effect of the solar panel.

[0045] Furthermore, the first solar panel 203 is a bifacial solar panel (specifically, it can be a bifacial low-light solar panel). The second side (not shown) of the first solar panel 203 is opposite to the first side 2041 of the circuit board 204, and the first side 2031 of the first solar panel 203 faces the first outer shell layer 201. The first side 2041 of the circuit board 204 is coated with a reflective material to reflect the light transmitted from the first outer shell layer 201, the button layer 202 and the first solar panel 203 to the second side of the first solar panel 203, so that the second side of the first solar panel 203 absorbs the reflected light and converts it into electrical energy, which is then transmitted to the circuit board 204.

[0046] In some embodiments, the reflective material may include reflective ink. Alternatively, other suitable materials with reflective properties may be used, such as metallic materials with good reflective properties (e.g., aluminum, silver).

[0047] In this embodiment of the invention, by using a double-sided solar panel as the first solar panel and combining it with a circuit board coated with reflective material, it is possible to further enable both sides of the first solar panel to absorb sunlight of a specific wavelength and convert it into electrical energy, while setting the size of the solar panel as large as possible, thereby effectively increasing the power generation.

[0048] Specifically, the first outer shell layer 201 has multiple through holes 2011, and the first surface 2021 of the button layer 202 has multiple buttons 2022. Each button 2022 corresponds to one of the multiple through holes 2011, and each button 2022 passes through the corresponding through hole 2011. In this way, each button 2022 of the button layer 202 can be more firmly fixed to the corresponding through hole 2011.

[0049] Furthermore, the function markings on the buttons 2022 of the button layer 202 are formed using a screen printing process.

[0050] Furthermore, the key layer 202 is made of transparent rubber, and diffusion powder is added to the transparent rubber.

[0051] By adding diffusion powder, the originally transparent rubber material button layer 202 can be made opaque in appearance while retaining a certain degree of light transmittance. Furthermore, by combining it with screen printing, each button 2022 can appear black or colored, thus achieving the light transmittance effect of the button layer 202 without affecting the appearance of the remote control.

[0052] Reference Figure 3 , Figure 3 This is an exploded view of the structure of another solar-powered remote controller 30 in this embodiment of the present invention. The solar-powered remote controller 30 and... Figure 2 The difference between the solar remote controller 20 shown is that the solar remote controller 30 can include, in addition to, Figure 2 The device structures shown may also include a second solar panel 205.

[0053] Specifically, the second solar panel 205 is located between the circuit board 204 and the second outer shell layer 206; the second outer shell layer 206 can transmit light within the target wavelength range, and the wavelength range of light that the second solar panel 205 can absorb is within the target wavelength range; wherein, the second solar panel 205 absorbs the light transmitted from the second outer shell layer 206 and converts it into electrical energy, which is then transmitted to the circuit board 204 to power the solar remote controller 20.

[0054] It is understandable that in the prior art, the light transmittance and solar power generation performance of the bottom or back of the solar remote control are usually not considered. Therefore, the bottom shell layer of the remote control is often made of completely opaque material. In contrast, this embodiment not only considers the light transmittance of the front of the solar remote control (corresponding to the first shell layer 201), but also the light transmittance and solar power generation performance of the bottom or back of the solar remote control (corresponding to the second shell layer 206).

[0055] Specifically, based on the first solar panel 203 with bifacial power generation capability, a second solar panel 205 is additionally added between the circuit board 204 and the second outer shell layer 206 (located at the bottom of the remote control). The second outer shell layer 206 is designed to be opaque yet translucent, and the wavelength range of light absorbed by the second solar panel 205 is within the wavelength range of light that the second outer shell layer 206 can transmit. Thus, the second outer shell layer 206 can function as a protective layer, allowing specific wavelengths of sunlight to pass through and be effectively absorbed by the second solar panel 205, without compromising the aesthetics of the remote control.

[0056] Furthermore, the second solar panel 205 can overlap with the circuit board 204 and the button layer 202 in vertical space. In other words, the projections of the second solar panel 205 and the circuit board 204, and the second solar panel 205 and the button layer 202 onto the plane of the second outer shell layer 206 can overlap. Therefore, given the limited size of the remote control, the size of the second solar panel 205 can be set as large as possible (e.g., close to the size of the second outer shell layer 206). In low-light indoor environments, this effectively increases the power generation of the second solar panel 205, ensuring sufficient power supply for the remote control and improving the user experience.

[0057] Furthermore, in actual use, the solar remote control can achieve solar power generation regardless of whether the front or back is facing up, thus achieving dual power generation. Especially in indoor light environments, it can also provide sufficient power generation.

[0058] Furthermore, the second solar panel 205 is a bifacial solar panel, with its second side 2052 facing the second side (not shown) of the circuit board 204, and its first side (not shown) facing the second outer shell layer 206. The second side of the circuit board 204 is coated with a reflective material to reflect light transmitted from the second outer shell layer 206 and the second solar panel 205 to the second side 2052 of the second solar panel 205, so that the second side 2052 of the second solar panel 205 absorbs the reflected light and converts it into electrical energy, which is then transmitted to the circuit board 204.

[0059] In this embodiment of the utility model, by using a bifacial solar panel as the second solar panel 205 and combining it with a circuit board 204 coated with reflective material, it is possible to make both sides of the second solar panel 205 absorb sunlight of a specific wavelength and convert it into electrical energy, while setting the size of the second solar panel 205 as large as possible. Based on this, combined with the first solar panel 203 with bifacial power generation function, the total power generation of the solar remote controller can be greatly increased.

[0060] exist Figure 2 and Figure 3 In the circuit, the two parallel solid lines on the first surface 2031 of the first solar panel 203 and the second surface 2052 of the second solar panel 205 are used to indicate the positive and negative electrodes and to make electrical connections with the circuit board 204. When the first solar panel 203 and the second solar panel 205 are bifacial solar panels, the second surface of the first solar panel 203 and the first surface of the second solar panel 205 may also be provided with positive and negative electrodes.

[0061] Regarding the electrical connection between the button layer 202 and the circuit board 204, the specific structure of the circuit board 204 and its electrical connection with the first solar panel 203 and the second solar panel 205 can be implemented using existing conventional methods, and this application does not impose any restrictions on this.
