DETAILED DESCRIPTION

[0048] The embodiments of the present application are described in detail below. Implementations of the embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0049] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] Electric vehicles are now popular due to their energy-saving and environmentally friendly advantages. Electric vehicles typically use an external power source to charge their batteries, which are used to provide power for driving and the operation of various electrical components. However, if the battery charge level is too low and there is no external power source nearby, the vehicle may become inoperable and its electrical components may not function. To address this issue, the present application provides a photovoltaic charging system 1000 and a vehicle 10000 (shown in Figure 1).

[0051] Referring to Figure 1 , a photovoltaic charging system 1000 according to an embodiment of the present application includes a photovoltaic charging assembly 200 and a charging cover assembly 100. The photovoltaic charging assembly 200 is used to convert solar energy into electrical energy. The charging cover assembly 100 includes a cover plate 14. When the cover plate 14 is closed, the photovoltaic charging assembly 200 is electrically connected to the battery 500 of the load. When the cover plate 14 is open, the electrical connection between the photovoltaic charging assembly 200 and the battery 500 of the load is disconnected.

[0052] Specifically, photovoltaic charging system 1000 is a structure for converting solar energy into electrical energy to charge a load electrically connected to photovoltaic charging system 1000. Loads that can be charged using photovoltaic charging system 1000 include, but are not limited to, vehicles, streetlights, water heaters, and solar fans. In this embodiment of the present application, the load is a vehicle 10000, and photovoltaic charging system 1000 is used to charge vehicle 10000.

[0053] The photovoltaic charging assembly 200 is a structure for converting light energy into electrical energy to charge other components. The photovoltaic charging assembly 200 of the present application is used to charge the battery 500 of the vehicle 10000.

[0054] When the cover plate 14 of the charging cover assembly 100 is open, an external power source can be electrically connected to the vehicle 10000 to charge the vehicle 10000. When the cover plate 14 of the charging cover assembly 100 is closed, the photovoltaic charging system 1000 and the battery 500 are connected, so that the photovoltaic charging system 1000 can charge the vehicle 10000.

[0055] When no external power source is available to charge the battery 500 of vehicle 10000, the cover 14 remains closed to prevent fumes and dust from entering the remaining components of the charging cover assembly 100, potentially damaging them. The cover 14 also serves as a decorative element, enhancing the overall aesthetics of vehicle 10000. Preferably, the cover 14 is made of the same material as the outer shell of vehicle 10000, ensuring a consistent and aesthetically pleasing appearance. The cross-sectional shape of the cover 14 may be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes.

[0056] In the photovoltaic charging system 1000 of the embodiment of the present application, when the cover 14 is in the closed state, the photovoltaic charging assembly 200 is used to charge the battery 500 of the load. When the cover 14 is in the open state, the photovoltaic charging assembly 200 stops charging the battery 500 of the load. When the vehicle 10000 is not charged by an external power source, the photovoltaic charging system 1000 of the present application is used to charge the vehicle 10000 to ensure that the battery 500 of the vehicle 10000 has sufficient power at all times, thereby avoiding the problem of the battery 500 of the vehicle 10000 being too low, resulting in the vehicle 10000 being unable to drive and the electrical components of the vehicle 10000 not being able to function.

[0057] The photovoltaic charging system 1000 is further described below with reference to the accompanying drawings.

[0058] Please refer to Figure 1. In some embodiments, the photovoltaic charging system 1000 also includes a vehicle control box 27 and a switch unit 300. The switch unit 300 electrically connects the photovoltaic charging component 200 and the battery 500 of the load. When the cover 14 is in the closed state, the switch unit 300 conducts the electrical connection between the photovoltaic charging component 200 and the battery 500 of the load; when the cover 14 is in the open state, the switch unit 300 disconnects the electrical connection between the photovoltaic charging component 200 and the battery 500 of the load.

[0059] When the photovoltaic charging assembly 200 is required to charge the battery 500 of the vehicle 10000, the switch unit 300 is used to conduct the electrical connection between the photovoltaic charging assembly 200 and the battery 500, so that the photovoltaic charging assembly 200 can charge the battery 500. When the photovoltaic charging assembly 200 is not required to charge the battery 500 of the vehicle 10000, the switch unit 300 is used to disconnect the electrical connection between the photovoltaic charging assembly 200 and the battery 500, so that the photovoltaic charging assembly 200 stops charging the battery 500.

[0060] In some embodiments, the switch unit 300 is a cover 14 that electrically connects the photovoltaic charging assembly 200 and the battery 500 as a load. When the cover 14 is closed, the cover 14 establishes the electrical connection between the photovoltaic charging assembly 200 and the battery 500 as a load. When the cover 14 is open, the cover 14 disconnects the electrical connection between the photovoltaic charging assembly 200 and the battery 500 as a load. For example, a relay structure is provided on the cover 14. When the cover 14 is closed, i.e., the circuits between the cover 14, the photovoltaic charging assembly 200, and the battery 500 as a load are all conductive, current flows through the relay, causing the relay to establish the electrical connection between the photovoltaic charging assembly 200 and the battery 500 as a load. When the cover 14 is open, i.e., the circuits between the cover 14, the photovoltaic charging assembly 200, and the battery 500 as a load are all disconnected, the current in the relay disappears, and the relay disconnects the electrical connection between the photovoltaic charging assembly 10 and the battery 500 as a load.

[0061] Please refer to Figures 1 to 3. In other embodiments, the charging cover assembly 100 further includes a sensor 13, which is electrically connected to the switch unit 300. When the cover 14 is in a closed state, the sensor 13 is used to output a first signal, which is used to enable the switch unit 300 to conduct the electrical connection between the photovoltaic charging assembly 200 and the battery 500 of the load; when the cover 14 is in an open state, the sensor 13 is used to output a second signal, which is used to enable the switch unit 300 to disconnect the electrical connection between the photovoltaic charging assembly 200 and the battery 500 of the load.

[0062] Specifically, the sensor 13 is a structure for detecting the open state and the closed state of the cover 14. The sensor 13 is also used to output a first signal and a second signal. The sensor 13 of the present application includes at least one of a pressure sensor, an image sensor, an infrared sensor, and an ultrasonic sensor.

[0063] In one embodiment, sensor 13 is a pressure sensor. When pressure from cover 14 acts on the pressure sensor, sensor 13 detects that cover 14 is closed, and sensor 13 outputs a first signal. When the pressure sensor detects no pressure from cover 14, sensor 13 detects that cover 14 is open, and sensor 13 outputs a second signal. In another embodiment, sensor 13 is an image sensor. The image sensor takes an image of cover 14 to calculate the distance between the image sensor and cover 14. When cover 14 is closed, the distance L between the image sensor and cover 14 is minimum. When the distance between the image sensor and cover 14 is L, sensor 13 detects that cover 14 is closed. When the distance between the image sensor and cover 14 is greater than L, sensor 13 detects that cover 14 is open. In yet another embodiment, sensor 13 is an infrared sensor. The distance between the infrared sensor and cover 14 is calculated from the time it takes for infrared light to be emitted by the infrared sensor and reflected back from the cover 14. When the cover 14 is in the closed state, the distance L between the infrared sensor and the cover 14 is minimum. When the distance between the infrared sensor and the cover 14 is L, the sensor 13 detects that the cover 14 is in the closed state. When the distance between the infrared sensor and the cover 14 is greater than L, the sensor 13 detects that the cover 14 is in the open state. In another embodiment, the sensor 13 is an ultrasonic sensor. The distance between the ultrasonic sensor and the cover 14 is calculated from the time it takes for the ultrasonic wave to hit the cover 14 and reflect back to the ultrasonic sensor. When the cover 14 is in the closed state, the distance L between the ultrasonic sensor and the cover 14 is minimum. When the distance between the ultrasonic sensor and the cover 14 is L, the sensor 13 detects that the cover 14 is in the closed state. When the distance between the ultrasonic sensor and the cover 14 is greater than L, the sensor 13 detects that the cover 14 is in the open state.

[0064] When the cover 14 is open, an external power source charges the battery 500 of the vehicle 10000. At this time, the sensor 13 detects that the cover 14 is open and transmits a second signal to the switch unit 300. Upon receiving the second signal, the switch unit 300 disconnects the electrical connection between the photovoltaic charging assembly 200 and the battery 500, thereby stopping the photovoltaic charging assembly 200 from charging the battery 500. When the cover 14 is closed, no external power source is charging the battery 500 of the vehicle 10000. The sensor 13 detects that the cover 14 is closed and transmits a first signal to the switch unit 300. Upon receiving the first signal, the switch unit 300 disconnects the electrical connection between the photovoltaic charging assembly 200 and the battery 500, thereby enabling the photovoltaic charging assembly 200 to charge the battery 500.

[0065] Referring to Figures 1, 3, and 4, in certain embodiments, the switch unit 300 includes a circuit breaker 301 and a signal collector 303. The circuit breaker 301 is electrically connected to the photovoltaic charging assembly 200 and the battery 500, respectively. The signal collector 303 is electrically connected to the circuit breaker 301, and the signal collector 303 is in communication with the charging cover assembly 100. When the signal collector 303 receives a first signal transmitted by the charging cover assembly 100, the circuit breaker 301 connects the electrical connection between the photovoltaic charging assembly 200 and the battery 500; when the signal collector 303 receives a second signal transmitted by the charging cover assembly 100, the circuit breaker 301 disconnects the electrical connection between the photovoltaic charging assembly 200 and the battery 500.

[0066] Specifically, circuit breaker 301 is a structure used to connect or disconnect an electrical circuit. Circuit breaker 301 typically consists of a contact system, an arc extinguishing system, an operating mechanism, a trip unit, and a housing. The specific structure of circuit breaker 301 will be described in detail below. When circuit breaker 301 connects the circuit between photovoltaic charging assembly 200 and battery 500, photovoltaic charging assembly 200 charges battery 500. When circuit breaker 301 disconnects the circuit between photovoltaic charging assembly 200 and battery 500, photovoltaic charging assembly 200 stops charging battery 500.

[0067] The signal collector 303 is used to collect the first signal and the second signal output from the charging cover assembly 100. In one embodiment, the signal collector 303 directly controls the circuit breaker 301 to connect or disconnect the electrical connection between the photovoltaic charging assembly 200 and the battery 500. When the signal collector 303 collects the first signal, the signal collector 303 controls the circuit breaker 301 to connect the electrical connection between the photovoltaic charging assembly 200 and the battery 500. When the signal collector 303 collects the second signal, the signal collector 303 controls the circuit breaker 301 to disconnect the electrical connection between the photovoltaic charging assembly 200 and the battery 500. In another embodiment, the switch unit 300 may further include a processor. When the signal collector 303 collects the first signal, the signal collector 303 transmits the first signal to the processor, which controls the circuit breaker 301 to connect the electrical connection between the photovoltaic charging assembly 200 and the battery 500. When the signal collector 303 collects the second signal, the signal collector 303 transmits the second signal to the processor, and the processor controls the circuit breaker 301 to disconnect the electrical connection between the photovoltaic charging assembly 200 and the battery 500 .

[0068] The charging cover assembly 100 transmits a signal to the switch unit 300, and the signal collector 303 receives the first signal or the second signal to control the circuit breaker 301 to open or close the circuit, thereby enabling the photovoltaic charging assembly 200 to automatically charge the battery 500 of the load or automatically stop charging the battery 500 of the load.

[0069] Please continue to refer to Figures 1, 3 and 4. Furthermore, in some embodiments, the switch unit 300 also includes a solar charging signal circuit 305, the circuit breaker 301 is arranged on the solar charging signal circuit 305, the input end 3051 of the solar charging signal circuit 305 is electrically connected to the photovoltaic panel 201 through the electrical connector 203 of the photovoltaic charging component 200, and the output end 3053 of the solar charging signal circuit 305 is electrically connected to the load battery 500.

[0070] The solar charging signal circuit 305 is used to electrically connect the photovoltaic charging assembly 200 and the battery 500, thereby conducting electricity between the photovoltaic charging assembly 200 and the battery 500, thereby enabling the photovoltaic charging assembly 200 to charge the battery 500. A circuit breaker 301 is provided on the solar charging signal circuit 305, which not only enables electrical conduction between the photovoltaic charging assembly 200 and the battery 500, but also controls the electrical disconnection between the photovoltaic charging assembly 200 and the battery 500. When the photovoltaic charging assembly 200 needs to charge the battery 500, the circuit breaker 301 conducts the solar charging signal circuit 305, thereby conducting electricity between the photovoltaic charging assembly 200 and the battery 500. When the photovoltaic charging assembly 200 does not need to charge the battery 500, the circuit breaker 301 disconnects the solar charging signal circuit 305, thereby disconnecting the photovoltaic charging assembly 200 and the battery 500.

[0071] The input end 3051 of the solar charging signal circuit 305 is electrically connected to the DC booster 205 via the electrical connector 203, thereby achieving electrical connection with the photovoltaic panel 201. The output end 3053 of the solar charging signal circuit 305 is electrically connected to the battery 500 via a wire. The electrical energy generated by the photovoltaic charging assembly 200 enters the solar charging signal circuit 305 from the input end 3051. When the circuit breaker 301 conducts the solar charging signal circuit 305, the electrical energy entering the solar charging signal circuit 305 is output from the output end 3053 of the solar charging signal circuit 305 to the battery 500 via a wire, thereby enabling the photovoltaic charging assembly 200 to charge the battery 500.

[0072] Referring to Figures 2 and 4 , in one embodiment, the sensor 13 is electrically connected to the signal collector 303 of the switch unit 300, and the sensor 13 is configured to output a first signal and a second signal to the signal collector 303. Specifically, when the sensor 13 detects that the cover 14 is in a closed state, the sensor 13 outputs the first signal to the signal collector 303. When the sensor 13 detects that the cover 14 is in an open state, the sensor 13 outputs the second signal to the signal collector 303.

[0073] In one example, a wired electrical connection is used between the sensor 13 and the signal collector 303. A wired electrical connection can connect the sensor 13 and the signal collector 303 via metal wires or optical fibers, enabling information to be transmitted between the sensor 13 and the signal collector 303. Wired electrical connections are highly reliable and less susceptible to interference. In this case, the switch unit 300 also includes a signal input terminal 307. The sensor 13 is connected to the signal input terminal 307 via metal wires or optical fibers, and the signal input terminal 307 is electrically connected to the signal collector 303, thereby electrically connecting the sensor 13 and the signal collector 303 and enabling communication between the sensor 13 and the signal collector 303. In another example, a radio connection is used between the sensor 13 and the signal collector 303. A radio connection uses electromagnetic wave signals propagating through space to transmit information between the sensor 13 and the signal collector 303. Radio connection methods include, but are not limited to, Bluetooth, wireless broadband, near-field communication (NFC), and infrared communication. Radio connections offer high information transmission speeds and do not require wires to connect the two communicating ends, resulting in lower costs.

[0074] Referring to Figures 2 and 4 , in another embodiment, the charging cover assembly 100 further includes a signal transmission element 15 , which is electrically connected to the sensor 13 and configured to transmit a first signal and a second signal emitted by the sensor 13 to a signal collector 303 of the switch unit 300 . When the sensor 13 detects that the cover 14 is closed, the sensor 13 emits a first signal to the signal transmission element 15 , which then outputs the first signal to the signal collector 303 . When the sensor 13 detects that the cover 14 is open, the sensor 13 emits a second signal to the signal transmission element 15 , which then outputs the second signal to the signal collector 303 .

[0075] In one example, a wired electrical connection is used between the signal transmission element 15 and the signal collector 303. The wired electrical connection can connect the signal transmission element 15 and the signal collector 303 via metal wires or optical fibers, enabling information to be transmitted between the signal transmission element 15 and the signal collector 303. Wired electrical connections are highly reliable and less susceptible to interference. In this case, the switch unit 300 also includes a signal input terminal 307. The signal transmission element 15 is connected to the signal input terminal 307 via metal wires or optical fibers. The signal input terminal 307 is electrically connected to the signal collector 303, thereby electrically connecting the signal transmission element 15 and the signal collector 303, enabling communication between the signal transmission element 15 and the signal collector 303. In another example, a radio connection is used between the signal transmission element 15 and the signal collector 303. A radio connection uses electromagnetic wave signals propagating in space to enable information to be transmitted between the signal input terminal 307 and the signal collector 303. Radio connection methods include, but are not limited to, Bluetooth, wireless broadband, near field communication (NFC), and infrared communication. Radio connections have a high information transmission speed and do not require wires to connect the two ends that need to communicate, which is low in cost. The charging cover assembly 100 of the embodiment of the present application includes a signal transmission member 15, and the signal transmission member 15 and the signal collector 303 are connected by wired electricity.

[0076] Please refer to Figures 1 and 2. Furthermore, in some embodiments, the charging cover assembly 100 also includes a shell 12, which is connected to a cover plate 14. The cover plate 14 can move relative to the shell 12. The shell 12 is provided with a charging interface 18. When the cover plate 14 moves to open the shell 12 and is in an open state, the charging interface 18 is used to connect to an external power supply to charge the battery 500 of the load; when the cover plate 14 moves to close the shell 12 and is in a closed state, the switch unit 300 conducts the electrical connection between the photovoltaic charging assembly 200 and the battery 500 of the load, so that the photovoltaic charging assembly 200 charges the battery 500.

[0077] The sensor 13, signal transmission element 15, and charging port 18 are all disposed on the housing 12. The charging port 18 is used to electrically connect to an external power source so that the external power source can charge the battery 500. The cover 14 can rotate or translate relative to the housing 12 to open or close the housing 12. The cross-sectional area of ​​the cover 14 is greater than or equal to the opening area of ​​the housing 12, so that when the cover 14 is closed, it can completely cover the housing 12, thereby preventing smoke, dust, etc. from falling on the charging port 18, sensor 13, and signal transmission element 15 on the housing 12.

[0078] In one embodiment, the cover 14 is rotatable relative to the housing 12. A rotating shaft may be provided between the cover 14 and the housing 12. When an external power source is required to charge the battery 500, the cover 14 is rotated toward a side away from the housing 12 to open the housing 12. When no external power source is provided to charge the battery 500, the cover 14 is rotated relative to the housing 12 to close the housing 12. In another embodiment, the cover 14 is translatable relative to the housing 12. When an external power source is required to charge the battery 500, the cover 14 is translated and slid to open the housing 12. When no external power source is provided to charge the battery 500, the cover 14 is translated and slid relative to the housing 12 to close the housing 12.

[0079] Referring to Figures 1 and 5 , in certain embodiments, a photovoltaic charging assembly 200 includes a photovoltaic panel 201, an electrical connector 203, and a DC booster 205. The photovoltaic panel 201 is configured to convert light energy into electrical energy. The electrical connector 203 is electrically connected to a battery 500 serving as a load via a switch unit 300. One end of the DC booster 205 is connected to the photovoltaic panel 201, and the other end is connected to the electrical connector 203. The DC booster 205 is configured to boost the electrical energy generated by the photovoltaic panel 201 to a voltage level acceptable for the battery 500 serving as a load, and transmit the electrical energy to the battery 500 serving as a load via the electrical connector 203.

[0080] Specifically, photovoltaic panel 201 is a structure that can generate a photovoltaic effect under sunlight, converting light energy into electrical energy to charge other components. Photovoltaic panel 201 is made of a semiconductor material, with silicon being the most commonly used material. Silicon can be either monocrystalline or polycrystalline. Photovoltaic panel 201 can be mounted on the surface of vehicle 10000. Preferably, photovoltaic panel 201 is mounted on the roof of vehicle 10000. In this case, the installation of photovoltaic panel 201 on vehicle 10000 is more stable, and the area of ​​photovoltaic panel 201 that can receive sunlight is larger. The larger the area of ​​photovoltaic panel 201, the more sunlight it can absorb, and thus the greater the amount of electrical energy converted. Therefore, when the area of ​​photovoltaic panel 201 is larger, the photovoltaic charging assembly 200 can charge battery 500 faster. However, the area of ​​the photovoltaic panel 201 should not be too large. If the area of ​​the photovoltaic panel 201 exceeds the area of ​​the top of the vehicle 10000 by a large amount, the photovoltaic panel 201 will increase the overall volume of the vehicle 10000 and there is a risk that the photovoltaic panel 201 will be installed unstable.

[0081] In one embodiment, the photovoltaic panel 201 is a single-piece structure and is not foldable. This makes processing of the photovoltaic panel 201 easier. In another embodiment, the photovoltaic panel 201 is a foldable structure. This makes storage easier. When not in use, the photovoltaic panel 201 can be folded and stored, eliminating the need for large space.

[0082] The voltage at the output of DC booster 205 is higher than the voltage at its input. DC booster 205 boosts the DC signal from photovoltaic panel 201 through components such as an inductor and a diode, ultimately outputting a voltage suitable for charging battery 500. DC booster 205 also monitors the charging process of battery 500 to prevent damage to battery 500 caused by excessive voltage or current, ensuring the stability and safety of the charging process.

[0083] The electrical energy generated by the photovoltaic panel 201 is boosted by the DC booster 205 to a voltage suitable for the battery 500. The electrical energy is then output from the DC booster 205 to the electrical connector 203. The electrical connector 203 is electrically connected to the switch unit 300. The electrical connector 203 transmits the electrical energy output from the DC booster 205 to the solar charging signal circuit 305 of the switch unit 300. The solar charging signal circuit 305 of the switch unit 300 is electrically connected to the battery 500, thereby outputting the electrical energy to the battery 500, enabling the photovoltaic charging assembly 200 to charge the battery 500.

[0084] Referring to FIG. 1 , an embodiment of the present application further provides a vehicle 10000 , which includes a photovoltaic charging system 1000 according to any of the above embodiments and a battery 500 . The photovoltaic charging system 1000 is used to charge the battery 500 . The battery 500 is a structure that provides electrical energy for driving the vehicle 10000 and operating electrical components within the vehicle 10000 .

[0085] In the vehicle 10000 according to the embodiment of the present application, when the cover 14 is closed, the photovoltaic charging assembly 200 is used to charge the battery 500 of the load. When the cover 14 is open, the photovoltaic charging assembly 200 stops charging the battery 500 of the load. When the vehicle 10000 is not being charged by an external power source, the photovoltaic charging system 1000 of the present application is used to charge the vehicle 10000 to ensure that the battery 500 of the vehicle 10000 has sufficient power at all times, thereby avoiding the problem of the battery 500 of the vehicle 10000 being too low, resulting in the vehicle 10000 being unable to drive and the electrical components of the vehicle 10000 not being able to function.

[0086] In addition, the current charging method for electric vehicles is to supplement the power supply by connecting the charging pile to the charging socket of the electric vehicle through a plug. Usually the charging socket of the electric vehicle is blocked by a cover. When charging is needed, the cover is opened and the plug is connected to the socket to supply power. In the related art, electric vehicles are equipped with solar panels. The electric energy output by the solar panels (photovoltaic panels) can also charge the battery of the electric vehicle. However, when switching between the two charging methods of charging using the charging pile plug and charging with the solar panel, the user needs to turn off one charging method and then turn on the other charging method, which is cumbersome to operate. To solve this problem, the present application provides a charging cover assembly (shown in Figure 6 or Figure 10), a photovoltaic charging system (shown in Figure 1) and a vehicle (shown in Figure 1 or Figure 9).

[0087] Referring to Figures 6 to 11, a charging cover assembly 100 implemented in the present invention includes a housing 12, a cover plate 14, and a switch member 20. The housing 12 is provided with a housing chamber 16, which is provided with a charging interface 18. The housing chamber 16 has an opening 121 on one side of the housing 12. The switch member 20 is configured to connect to the solar charging signal circuit 305 of the vehicle 10000. The cover plate 14 is movably connected to the housing 12. When the cover plate 14 closes the opening 121, the cover plate 14 is configured to drive the switch member 20 to conduct to control the solar charging signal circuit 305 to conduct. When the cover plate 14 opens the opening 121, the cover plate 14 is configured to drive the switch member 20 to disconnect to control the solar charging signal circuit 305 to disconnect.

[0088] In the above-mentioned charging cover assembly 100, by driving the switch component 20 to conduct when the cover 14 is closed and driving the switch component 20 to disconnect when it is opened, the solar charging signal circuit 305 can be disconnected and conducted, thereby realizing switching between two charging modes: charging with other power sources and charging with solar panels, reducing user operations and improving user experience.

[0089] Specifically, the charging cap assembly 100 can be used on a vehicle 10000, including but not limited to pure electric vehicles, extended-range electric vehicles, hybrid vehicles, and gasoline vehicles. The charging cap assembly 100 can be installed at the front, rear, or left or right sides of the vehicle, without specific limitations. Other power sources include but are not limited to charging stations and other vehicles 10000.

[0090] The switch element 20 can be disposed within the accommodating cavity 16 or can be configured as an integral structure with the housing 12, and this is not specifically limited here. Referring to FIG9 , the vehicle 10000 comprises a battery 500 and a vehicle control box 27. The battery 500 can be charged by connecting to another power source (such as a charging station) via the charging port 18. The battery 500 can be a power battery or a storage battery, and this is not specifically limited here. The power battery can serve as a source of power energy to propel the vehicle 10000. The vehicle 10000 has a built-in photovoltaic charging assembly 100. As previously mentioned, the photovoltaic charging assembly 100 can include a solar panel (photovoltaic panel 201), which can be mounted on the roof of the vehicle 10000. The vehicle control box 27 is electrically connected to the two connection terminals of the photovoltaic charging assembly 100. The vehicle control box 27 is electrically connected to the circuit breaker 301 and is used to control the closing or opening of the circuit breaker 301. When the circuit breaker 301 is closed, the vehicle control box 27 can use the electrical energy output by the photovoltaic charging assembly 100 to charge the battery 500. When the circuit breaker 301 is disconnected, the photovoltaic charging assembly 100 stops charging the battery 500 .

[0091] The circuit breaker 301 can be electrically connected to the switch element 20. When the cover 14 closes the opening 121, the cover 14 drives the switch element 20 to turn on, and the solar charging signal circuit 305 connected to the switch element 20 is turned on. The solar charging signal circuit 305 outputs a control signal. The vehicle control box 27 can control the circuit breaker 301 to close according to the control signal, and then when the cover 14 of the vehicle charger cover is closed, the photovoltaic charging assembly 100 can charge the battery 500.

[0092] When the cover 14 opens to opening 121, the cover 14 drives the switch 20 to disconnect, disconnecting the solar charging signal circuit 305. The control signal cannot be transmitted to the vehicle control box 27. The vehicle control box 27 can then control the circuit breaker 301 to disconnect. As a result, when the cover 14 of the vehicle charger cover is opened, the photovoltaic charging assembly 100 stops charging the battery 500. When the cover 14 opens to opening 121, the user can use another power plug to plug into the charging port 18 in the accommodating cavity 16 to charge the battery 500 from another power source.

[0093] The utility model utilizes the cover plate 14 of the charging cover assembly 100 to switch on and off, and completes the switching of the vehicle photovoltaic and other power charging modes without adding additional redundant instructions from the user, thereby simplifying user operations and improving user experience.

[0094] Optionally, the cover plate 14 may be rotatably connected to the housing 12 or slidably connected to the housing 12. In the embodiment shown in FIG6 , the cover plate 14 is rotatably connected to the housing 12, and the opening 121 is opened and closed by the rotation of the cover plate 14.

[0095] In some embodiments, referring to Figures 10 and 11, the switch 20 includes a movable trigger portion 22. When the cover 14 closes the opening 121, the cover 14 presses against the trigger portion 22 to turn on the switch 20. When the cover 14 opens the opening 121, the cover 14 separates from the trigger portion 22 to turn off the switch 20.

[0096] In this way, the switch element 20 can be driven to be turned on and off by the cover plate 14 pressing against the trigger portion 22 and separating from the trigger portion 22 .

[0097] Specifically, when the cover 14 closes the opening 121, the cover 14 presses against the trigger part 22, the trigger part 22 is pressed, the switch 20 is turned on, and the solar charging signal circuit 305 connected to the switch 20 is turned on. The solar charging signal circuit 305 outputs a control signal, and the vehicle control box 27 can control the circuit breaker 301 to close according to the control signal, and then when the cover 14 of the vehicle charger cover is closed, the photovoltaic charging assembly 100 can charge the battery 500.

[0098] When the cover 14 opens the opening 121, the cover 14 separates from the trigger part 22, the trigger part 22 resets, the switch 20 is disconnected, the solar charging signal circuit 305 is disconnected, and the control signal cannot be transmitted to the vehicle control box 27. The vehicle control box 27 can control the circuit breaker 301 to disconnect, and then when the cover 14 of the vehicle charger cover is opened, the photovoltaic charging assembly 100 stops charging the battery 500.

[0099] In some embodiments, the switch member 20 includes a body 21 and a spring 23. The trigger portion 22 and the spring 23 are installed on the same side of the body 21. The side of the spring 23 facing the body 21 abuts against the side of the trigger portion 22 away from the body 21. When the cover 14 closes the opening 121, the cover 14 presses the trigger portion 22 through the spring 23.

[0100] In this way, the sensitivity of the switch element 20 can be increased.

[0101] Specifically, one end of the spring clip 23 is fixed to a side surface of the body 21, and the trigger portion 22 is retractably protruded from the same side surface of the body 21. The side of the spring clip 23 facing the body 21 abuts the side of the trigger portion 22 facing away from the body 21. When the cover 14 closes the opening 121, the cover 14 can first press the spring clip 23, causing it to press the trigger portion 22, causing it to retract into the body 21, thereby energizing the circuit within the body 21 and, in turn, the signal loop. When the spring clip 23 is pressed, it stores elastic potential energy.

[0102] During the process of the cover 14 opening the opening 121, the cover 14 rotates, causing one end of the cover 14 to move away from the accommodating cavity 16, and the cover 14 releases the spring 23. The elastic potential energy causes the spring 23 to quickly reset, causing the trigger part 22 to extend out of the main body 21 faster. The circuit in the main body 21 is disconnected, and the photovoltaic charging assembly 100 stops charging the battery 500.

[0103] In one embodiment, the switch member 20 may include a micro switch.

[0104] In some embodiments, referring to FIG. 7 , when the cover 14 closes the opening 121 , a pressing block 141 is protruded from the side of the cover 14 facing the accommodating cavity 16 , and the pressing block 141 presses the trigger portion 22 .

[0105] In this way, the wear of the cover plate 14 is reduced and the service life of the cover plate 14 is extended.

[0106] Specifically, because vehicle 10000 is a commodity used for extended periods of time, cover plate 14 often needs to be opened to charge vehicle 10000. Without pressing block 141, cover plate 14 would come into direct contact with trigger portion 22 when closed, causing scratches when pressing trigger portion 22. By pressing block 141 against trigger portion 22, scratches on cover plate 14 can be reduced, thereby reducing wear and tear on cover plate 14 and extending its service life.

[0107] Furthermore, in FIG. 11 , the switch member 20 is provided with an elastic piece 23 . When the cover plate 14 closes the opening 121 , the cover plate 14 presses the trigger portion 22 through the pressing block 141 and the elastic piece 23 .

[0108] In some embodiments, a boss 19 is provided in the accommodating cavity 16, and a groove 191 is formed in the boss 19. The switch member 20 is accommodated in the groove 191. A notch 193 is provided on the side wall of the groove 191 facing the opening 121. When the cover 14 closes the opening 121, the cover 14 presses the trigger portion 22 through the notch 193.

[0109] In this way, the switch element 20 can be prevented from obstructing the insertion of other power plugs.

[0110] Specifically, in Figure 10, the boss 19 is provided on the bottom wall of the accommodating cavity 16, and the charging interface 18 is provided at the upper part of the accommodating cavity 16. The boss 19 leaves space above for other power plugs to be inserted into the charging interface 18. The switch 20 is located in the groove 191 opened by the boss 19, which will not hinder the insertion of other power plugs, thereby ensuring the convenience of inserting other power plugs.

[0111] In addition, the switch element 20 is located in the groove 191 , which can also protect the switch element 20 , preventing the switch element 20 from being accidentally damaged and affecting the service life, thereby ensuring the reliability of the switch element 20 .

[0112] In some embodiments, a fixing portion 44 and a positioning portion 46 are provided in the groove 191, and the switch member 20 is provided with a fixing hole (not shown) and a positioning hole 48. The fixing portion 44 is arranged corresponding to the fixing hole, and the positioning portion 46 is passed through the positioning hole 48. The charging cover assembly 100 includes a fastener 50, which passes through the fixing hole and is connected to the fixing portion 44.

[0113] In this way, the switch element 20 can be fixed to prevent the switch element 20 from shifting and affecting the operation of the switch element 20 .

[0114] Specifically, in one embodiment, the fastener 50 is a screw, which can be used to secure the switch 20 with good securing effect. Moreover, the switch 20 is detachably mounted in the groove 191, which facilitates maintenance and replacement of the switch 20. In other embodiments, the fastener 50 can be a pin or other fastener 50, which is not specifically limited herein.

[0115] The setting of the positioning portion 46 and the positioning hole 48 can position the switch component 20 before fixing the switch component 20, so that the fixing hole of the switch component 20 corresponds to the position of the fixing portion 44, and then the fastener 50 is used to penetrate the fixing hole and connect it to the fixing portion 44, thereby improving the installation efficiency of the switch component 20.

[0116] In one embodiment, the positioning portion 46 is cylindrical, and the positioning hole 48 is a cylindrical hole.

[0117] In some embodiments, a reinforcing rib 52 is provided in the groove 191 , and the switch member 20 is fixed on the reinforcing rib 52 . The reinforcing rib 52 connects the side wall of the groove 191 , the fixing portion 44 , and the positioning portion 46 .

[0118] In this way, the structural strength of the fixing portion 44 and the positioning portion 46 can be increased, thereby improving the reliability of the switch element 20 .

[0119] Specifically, the reinforcing rib 52 connects the side wall of the groove 191, the fixing portion 44 and the positioning portion 46, so that the fixing portion 44 and the positioning portion 46 are connected to each other and to the boss 19 through the reinforcing rib 52, thereby strengthening the structural strength of the fixing portion 44 and the positioning portion 46, providing a more stable fixing platform for the switch component 20, and improving the reliability of the switch component 20.

[0120] In FIG. 11 , the reinforcing rib 52 connects the left side wall, the right side wall, and the rear side wall of the groove 191 .

[0121] In some embodiments, a through hole 54 is defined on the sidewall of the groove 191 facing the notch 193 . The charging cover assembly 100 includes a cable 56 , and the switch element 20 includes a conductive terminal 58 . The cable 56 is connected to the conductive terminal 58 and passes through the through hole 54 .

[0122] In this way, it is convenient to connect the external device of the charging cover assembly 100 to the switch member 20 .

[0123] Specifically, in Figure 11, the through hole 54 is opened on the rear side wall of the groove 191, and the switch member 20 includes two conductive terminals 58, each conductive terminal 58 is connected to a cable 56, and the two cables 56 pass through the charging cover assembly 100 through the through hole 54. One cable 56 can be connected to one end of the signal loop, and the other cable 56 can be connected to the other end of the signal loop, or the two cables 56 are part of the signal loop and are respectively connected to the two conductive terminals 58.

[0124] In some embodiments, when the cover 14 closes the opening 121 , a locking block 60 is protruded from the side of the cover 14 facing the accommodating cavity 16 , and a locking hole 62 is defined in the boss 19 , in which the locking block 60 is locked.

[0125] In this way, when the cover plate 14 closes the opening 121 , the cover plate 14 can be fixed to prevent the cover plate 14 from shaking during the driving of the vehicle 10000 .

[0126] Specifically, in Figure 6 , two latching blocks 60 are protruding from the side of the cover plate 14 facing the accommodating cavity 16. The boss 19 defines two latching holes 62, with each latching block 60 correspondingly latched in one of the latching holes 62. It should be understood that the present invention does not impose any specific limitation on the number of latching blocks 60 and latching holes 62. The latching blocks 60 are latched in the latching holes 62 to secure the cover plate 14.

[0127] Furthermore, an operation hole 64 is formed on the side of the cover plate 14 facing away from the accommodating cavity 16 . The operation hole 64 can provide a fulcrum for the user, making it easier for the user to open the cover plate 14 .

[0128] In some embodiments, when the cover 14 opens the opening 121 , a portion of the cover 14 covers a portion of the outer side surface of the housing 12 , and the opening 121 is located below the cover 14 .

[0129] In this way, when the cover 14 is opened, water can be prevented or reduced from flowing into the accommodating cavity 16 .

[0130] Specifically, the vehicle 10000 is sometimes charged outdoors, and there may be no rain shelter when charging outdoors. When it rains, rainwater may enter the interior of the charging cover assembly 100, posing a short-circuit risk to charging. In this embodiment, when the cover 14 opens the opening 121, it may refer to when the cover 14 is at its maximum opening stroke. Referring to Figures 10 and 12, when the cover 14 opens the opening 121, a portion of the cover 14 covers a portion of the upper side of the shell 12, and the opening 121 is located below the cover 14. Therefore, when rainwater falls from a high place, all or part of the rainwater will be blocked by the cover 14 and cannot enter the accommodating chamber 16 through the opening 121. Therefore, it can prevent or reduce water from flowing into the accommodating chamber 16, thereby improving the safety of the vehicle 10000 when charging with other power sources.

[0131] In Figure 8, the cover 14 is rotatably connected to the housing 12 via a rotation mechanism 66. Specifically, the rotation mechanism 66 includes a first connector 68, a second connector 70, and a third connector 72. One end of the first connector 68 is rotationally connected to the upper sidewall of the accommodating cavity 16, and the other end is rotationally connected to one end of the second connector 70. The other end of the second connector 70 is rotationally connected to one end of the third connector 72. The other end of the third connector 72 is fixedly connected to the cover 14. When the cover 14 opens the opening 121, a portion of the cover 14 can extend above the upper side of the housing 12, covering a portion of the upper side of the housing 12.

[0132] In some embodiments, referring to FIG. 13 , the switch element 20 includes a magnetically controlled switch 74 .

[0133] In this way, the magnetic control principle can be used to control the conduction and disconnection of the switch.

[0134] Specifically, the cover 14 can be made of a magnetic material, or a magnetic member can be provided on the side wall of the cover 14 facing the accommodating cavity 16. When the cover 14 closes the opening 121, the magnetic switch 74 can detect the magnetic field of the cover 14 or the magnetic member, triggering the magnetic switch 74 to conduct, thereby energizing the solar charging signal circuit 305. When the cover 14 opens the opening 121, the magnetic switch 74 no longer detects the magnetic field and is disconnected, thereby disconnecting the solar charging signal circuit 305.

[0135] A photovoltaic charging system according to an embodiment of the present invention is used to charge a battery 500 of a vehicle 10000. The photovoltaic charging system includes a charging cover assembly 100 according to any of the above embodiments and a solar panel. The solar panel is electrically connected to the battery 500 via a switch 20 of the charging cover assembly 100.

[0136] A vehicle 10000 according to an embodiment of the present invention includes the photovoltaic charging system according to the above embodiment.

[0137] In the above-mentioned vehicle 305, by driving the switch component 20 to conduct when the cover 14 is closed and driving the switch component 20 to disconnect when it is opened, the solar charging signal circuit 305 can be disconnected and conducted, realizing switching between charging modes of other power sources and charging of solar panels, reducing user operations and improving user experience.

[0138] Specifically, the vehicle 10000 may include, but is not limited to, a pure electric vehicle, an extended-range electric vehicle, a hybrid vehicle, a fuel vehicle, etc. The charging cover assembly 100 may be installed at the front, rear, left or right sides of the vehicle, etc., without specific limitation.

[0139] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there are no conflicts in the combination of these technical features, they should be considered to be within the scope of this specification.
