Description

Technical Field

[0001] This application relates to the field of automotive rearview mirror technology, and more particularly to a rearview mirror that continuously maintains GPS positioning functionality. Background Technology

[0002] Currently, the vehicle's GPS positioning is based on the vehicle being powered while in motion. Once the car is parked, GPS positioning cannot be obtained. This may lead to situations where the car is unable to move due to geological issues in mountainous areas, and the lack of signal in mountainous areas may prevent people from receiving rescue quickly. Utility Model Content

[0003] The purpose of this application is to provide a rearview mirror that can maintain GPS positioning by using solar charging.

[0004] To achieve the above objectives, this application provides a rearview mirror that continuously maintains GPS positioning functionality: it includes a base, a transparent front cover fixedly connected to the upper edge of the base, a solar charging patch fixedly disposed on the inner wall of the transparent front cover, a junction box, a miniature GPS locator, and a lithium battery board disposed on the base, the solar charging patch being electrically connected to the junction box, the junction box being electrically connected to both the miniature GPS locator and the lithium battery board, the lithium battery board being electrically connected to the miniature GPS locator, and a lens being fixedly connected to the rear edge of the transparent front cover and the base, for assisting the driver in observing the situation behind the vehicle.

[0005] As a preferred embodiment, the junction box is electrically connected to the miniature GPS locator via a first power supply line, allowing the solar charging patch to directly power the miniature GPS locator.

[0006] As a preferred embodiment, the junction box is electrically connected to the lithium battery panel via a second power supply line, enabling the solar charging patch to charge the lithium battery panel.

[0007] As a preferred embodiment, the lithium battery board is electrically connected to the miniature GPS locator via a third power supply line, so that the miniature GPS locator is powered by the lithium battery board in the absence of light.

[0008] As a preferred embodiment, the base is also equipped with a controller, which is electrically connected to the lithium battery panel and can be charged using the car's main battery.

[0009] As a preferred embodiment, the base also has through holes extending through the upper and lower surfaces, suitable for the vehicle's signal and power lines to pass through and be electrically connected to the controller, for providing power to components such as the heating element and warning light inside the rearview mirror and controlling their operation.

[0010] As a preferred embodiment, the solar charging patch is divided into several pieces, and the edges of these solar charging patches are closely attached to form the same curved surface as the inner wall of the transparent front cover. All the solar charging patches are connected in series and then connected to the junction box, so that the solar charging patches can output sufficient electrical energy.

[0011] As a preferred option, the transparent front cover is made of PMMA acrylic material, which balances light transmittance and high strength.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) By designing components such as solar charging pads and lithium battery panels, the micro GPS locator can be provided with continuous power alternately, thereby effectively ensuring that the vehicle can be located under any working condition and reducing the risk of disconnection after the vehicle enters deep mountains or experiences an abnormal power outage. (2) By designing the front cover of the rearview mirror to be transparent and attaching a solar charging patch structure to the inside of the transparent front cover, the transparent front cover can ensure the light of the solar charging patch, while the opaque solar charging patch can block the internal structure of the rearview mirror housing, so that the entire rearview mirror remains aesthetically pleasing.

[0019] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0021] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0023] like Figure 1-5 The rearview mirror shown here, which maintains GPS positioning function continuously, includes a base 1. The base 1 is movably connected to the car rearview mirror bracket and can be driven by the drive mechanism inside the car rearview mirror bracket to adjust the angle relative to the car door. This function and the mechanism for realizing it are prior art and are not part of the design points of this application, so they will not be described in detail here. A transparent front cover 3 is fixedly connected to the upper edge of the base 1. The transparent front cover 3 is made of PMMA acrylic material, which has good light transmittance and structural strength. A solar charging patch 4 is fixedly installed on the inner wall of the transparent front cover 3. This is the core component of the photovoltaic panel and can be used to convert light energy into electrical energy.

[0024] The solar charging pad 4 is divided into several pieces. The edges of these solar charging pads 4 are tightly attached to form the same curved surface as the inner wall of the transparent front cover 3. The manufacturing process and connection method of each solar charging pad 4 may be a little complicated, but it is entirely feasible. The advantage of this design is that the entire solar charging pad 4 has high light-gathering efficiency from multiple angles. The base 1 is equipped with a junction box 5, a miniature GPS locator 6, and a lithium battery panel 7. Although the transparent front cover 3 is transparent, the solar charging pad 4 is opaque, so the junction box 5, the miniature GPS locator 6, and the lithium battery panel 7 will be blocked and not visible, without affecting the overall aesthetic appearance of the car rearview mirror. The solar charging pad 4 is electrically connected to the junction box 5. Under normal circumstances, all the solar charging pads 4 are connected in series to the junction box 5, so that sufficient voltage can be provided even in weak ambient light.

[0025] The junction box 5 contains a circuit board with voltage regulators and other functional components, which helps the solar charging patch 4 output a stable voltage. This is a technology in electronic circuits, and the technology is mature and feasible, but it is not the focus of this application and will not be elaborated here. The junction box 5 is electrically connected to both the mini GPS locator 6 and the lithium battery board 7. Specifically: the junction box 5 is electrically connected to the mini GPS locator 6 through the first power supply line 56. In the presence of ambient light, the solar charging patch 4 can directly power the mini GPS locator 6. The junction box 5 is electrically connected to the lithium battery board 7 through the second power supply line 57. In the presence of ambient light, the solar charging patch 4 can charge the lithium battery board 7. The lithium battery board 7 is electrically connected to the mini GPS locator 6. The lithium battery board 7 is also electrically connected to the mini GPS locator 6 through the third power supply line 67. In the absence of ambient light, the lithium battery board 7 can also power the mini GPS locator 6.

[0026] The transparent front cover 3 and the rear edge of the base 1 are jointly fixed to the lens 2, which is the main component for realizing the rearview function of the car. The base 1 is also equipped with a controller 8, which is used to control other working components inside the rearview mirror, such as the heating structure to prevent the lens 2 from becoming blurry, and the warning light to remind the driver. The controller 8 is also electrically connected to the lithium battery panel 7. The base 1 is also provided with a through hole 101 that runs through the upper and lower surfaces, which is used for the vehicle's signal line and power line to pass through and be electrically connected to the controller 8. In this way, the car's main battery can charge the lithium battery panel 7 through the controller 8. So even if the vehicle is in a dark environment for a long time, as long as the vehicle still has power or fuel, the miniature GPS locator 6 can be activated to send out location information.

[0027] Working principle: During the day, when the ambient light is strong, the solar charging patch 4 supplies power to the mini GPS locator 6 while simultaneously charging the depleted lithium battery panel 7 until it is fully charged. The lithium battery panel 7 also has a power control circuit board that automatically stops charging once it detects that the battery is fully charged. At night, when the ambient light is weak, the solar charging patch 4 cannot generate enough power to supply the mini GPS locator 6. The lithium battery panel 7 then takes over from the solar charging patch 4 to power the mini GPS locator 6. This allows for stable transmission of positioning signals even in the absence of light at night. Since the mini GPS locator 6 consumes relatively little power, the lithium battery panel 7 can last all night and can be recharged at dawn.

[0028] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
