Description

Technical Field

[0002] The integrated photovoltaic-storage-charging hybrid control device for new energy vehicles is an energy management system that integrates photovoltaic power generation, energy storage systems, and charging facilities.

An air guide hole 44 is opened in the inner side of the second protective shell 41. A connecting plate 45 is fixedly connected to the rear end of the second protective shell 41 near the air guide hole 44. A through hole 46 is opened in the inner side of the connecting plate 45. A spring telescopic rod 47 is fixedly connected to the front end of the connecting plate 45. A spherical block 48 is fixedly connected to the front end of the spring telescopic rod 47. A rubber ring 49 is fixedly connected to the rear end of the spherical block 48. The front end of the control box housing 31 is fixedly connected to the rear end of the second protective shell 41 by bolts.

[0031] As a further implementation of this solution, a bracket 5 is fixedly connected to the top of the substrate 1, and a photovoltaic device 2 is fixedly connected to the top of the bracket 5. The top of the substrate 1 is fixedly connected to the bottom of the control box shell 31. Through the above arrangement, the photovoltaic device 2 charges the hybrid control device assembly 3. The bracket 5 supports the photovoltaic device 2, and the photovoltaic device 2 can provide certain protection for the hybrid control device assembly 3.

[0032] As a further implementation of this solution, the wiring hole 32 penetrates the lower end of the control box housing 31, the inner side of the control box housing 31 is hollow, the first mounting groove 34 penetrates the rear end of the control box housing 31, the second mounting groove 35 penetrates the front end of the control box housing 31, the first fan assembly 36 and the second fan assembly 39 have the same structure, the first fan assembly 36 is equipped with an electric fan, the first fan assembly 36 has a through hole near the electric fan, the filter hole 38 penetrates the lower end of the first protective shell 37, the inner side of the first protective shell 37 is hollow, the front end of the first protective shell 37 has a through structure, and the filter hole 38 is connected to the inner side of the first protective shell 37. Through the above settings, the humidity of the outside and inside of the control box housing 31 can be detected in real time, and then the controller can control the direction of air blowing of the electric fans of the first fan assembly 36 and the second fan assembly 39. This can change the heat dissipation method inside the control box housing 31, improve the stability and safety of the device, and enhance its adaptability and practicality in different environments.

[0033] As a further implementation of this solution, the inner side of the second protective shell 41 is hollow, and the rear end of the second protective shell 41 is a through structure. The opening 42 penetrates the lower end of the second protective shell 41 and communicates with the inner side of the second protective shell 41. The through hole 46 communicates with the air guide hole 44. The spring telescopic rod 47 is embedded in the air guide hole 44. A gap is provided between the outer side of the spring telescopic rod 47 and the inner side of the air guide hole 44. The rear end of the spherical block 48 is an arc-shaped groove structure. The rear end of the rubber ring 49 is attached to the front end of the activated carbon plate 43. Through the above settings, moisture and impurities in the air can be absorbed and filtered, thereby ensuring that the gas entering the control box shell 31 contains low moisture content, improving the safety of the device. At the same time, when the mixing control device assembly 3 changes the airflow direction, the activated carbon plate 43 can be dried and impurities removed, thereby improving the service life of the activated carbon plate 43.

[0034] Workflow: During rainy weather, when the control box 31 is cooled, the humidity sensor 33 detects the humidity inside the control box 31. Humidity sensors 33 are installed both inside and outside the control box 31 to sense the humidity of the external environment and simultaneously detect the humidity inside the control box 31. This allows control over the drying time of the activated carbon plate 43. Wiring can be threaded through the wiring hole 32 to connect to the electrical equipment inside the control box 31. The control box 31 contains a controller, humidity sensor 33, an electric fan in the second fan assembly 39, and an electric fan in the first fan assembly 36. The controller is electrically connected to the control box housing 31. When the humidity inside the control box housing 31 is high, the controller starts the electric fans of the second fan assembly 39 and the first fan assembly 36. At this time, the airflow is from front to back. The outside air enters the second protective housing 41 through the opening 42, and then passes through the activated carbon plate 43 to filter the moisture and impurities in the air. The filtered air enters the control box housing 31 through the second fan assembly 39, and then enters the first protective housing 37 through the first fan assembly 36, and then flows out through the filter hole 38, thereby achieving the effect of heat dissipation inside the control box housing 31.

[0035] On sunny days, the humidity sensor 33 detects the humidity inside and outside the control box housing 31. If the humidity inside the control box housing 31 is low, the controller activates the electric fans of the second fan assembly 39 and the first fan assembly 36. The air flows from back to front, with outside air entering the control box housing 31 through the filter 38, the inside of the first protective shell 37, and the inside of the first fan assembly 36, thus achieving heat dissipation. Simultaneously, the hot air from the control box housing 31 can be brought into contact with the activated carbon plate 43 via the second fan assembly 39. The airflow from the second fan assembly 39 flows through the through hole 46 and the air guide hole 44. The airflow from the second fan assembly 39 is greater than the elastic force of the spring telescopic rod 47. At this time, the spherical block 48 will move forward and drive the spring telescopic rod 47 to extend. At this time, the rubber ring 49 moves away from the activated carbon plate 43. The rubber ring 49 can improve the sealing effect between the through hole 46 and the activated carbon plate 43. At this time, the hot air is blown out from the arc groove of the spherical block 48 to the surrounding area. The hot air dries the front end of the activated carbon plate 43 and removes the debris from the front end of the activated carbon plate 43, thus improving the service life of the activated carbon plate 43.

[0036] In summary, the device can implement different heat dissipation methods for the inside of the control box 31 in rainy or sunny weather, thereby ensuring that the control box 31 is cooled down. At the same time, it can prevent moisture from affecting the electrical equipment inside the control box 31 and improve the practicality of the device.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
