Technical Field
[0001] This utility model relates to the technical field of lawnmowers, and more particularly to a smart lawnmower photovoltaic charging device. Background Technology
[0002] With the development of science and technology, environmentally friendly and intelligent robotic lawnmowers have gradually appeared in the public eye. Due to their advantages such as safety, quiet operation, and high level of intelligence, they have become a new favorite in the lawnmower market. Therefore, the replacement of traditional lawnmowers by intelligent lawnmowers has become a trend. However, for intelligent lawnmowers, how to control them during mowing operations and enable them to recharge in a timely manner is a technical problem that needs to be solved. Utility Model Content
[0003] This invention addresses the shortcomings of existing technologies, such as lawnmowers not being charged in a timely manner and requiring manual retrieval and restart, by providing a new intelligent photovoltaic charging device for lawnmowers.
[0004] To solve the above-mentioned technical problems, the utility model provides the following technical solution: A smart lawnmower photovoltaic charging device includes a photovoltaic station and a charging pile. The photovoltaic station includes a shell, a solar panel, an energy storage pack, an energy harvesting management circuit board, and a connecting cable. The photovoltaic station is electrically connected to the charging pile through the connecting cable. The energy storage pack and the energy harvesting management circuit board are disposed inside the shell. The energy harvesting management circuit board is electrically connected to the solar panel through the connecting cable. The energy storage pack is electrically connected to the energy harvesting management circuit board. The energy harvesting management circuit board is used to detect the power status of the solar panel and energy storage pack and control the solar panel and energy storage pack to charge the lawnmower, or control the solar panel to charge the energy storage pack; the energy harvesting management circuit board controls the charging pile to send out a boundary signal for the lawnmower to recognize based on the power status of the solar panel and energy storage pack.
[0005] The energy harvesting management circuit board can intelligently adjust the charging of the lawnmower by the solar panels and energy storage pack based on their power levels. This allows the solar panels and energy storage pack to charge the lawnmower individually or simultaneously, adapting to different situations and improving the lawnmower's charging efficiency. This prevents the lawnmower from being left idle due to insufficient charging and requiring manual intervention. When the lawnmower is fully charged, the solar panels can charge the energy storage pack, maximizing the collection and utilization of photovoltaic-converted green energy and saving energy.
[0006] Preferably, the aforementioned intelligent lawnmower photovoltaic charging device includes a parking compartment for the lawnmower, a route management circuit board, and a boundary line. The boundary line is set at the boundary of the site, and the route management circuit board is electrically connected to the boundary line and determines the boundary range based on the boundary line, emitting a boundary signal for the lawnmower to recognize.
[0007] Preferably, in the above-described intelligent lawnmower photovoltaic charging device, the energy harvesting management circuit board sends a charging signal or a return-to-base sleep signal to the route management circuit board based on the power status of the solar panel and energy storage pack. The route management circuit board converts the received charging signal or return-to-base sleep signal into a boundary signal for the lawnmower to identify and return to the base for charging or sleep. The boundary signal is formed by the route management circuit board regularly opening or closing the boundary line.
[0008] Preferably, in the above-described intelligent lawnmower photovoltaic charging device, the energy harvesting management circuit board controls the solar panel or energy storage pack to supply power to the energy harvesting management circuit board and the route management circuit board.
[0009] Preferably, in the above-mentioned intelligent lawnmower photovoltaic charging device, the energy harvesting management circuit board is provided with a power value W1 and a power value U1. The energy harvesting management circuit board monitors the power status of the solar panel and the energy storage pack and compares it with the power value W1 and the power value U1. If the power of the solar panel is greater than or equal to the power value W1, and the power of the energy storage pack is greater than or equal to the power value U1, the energy harvesting management circuit board controls the solar panel or the energy storage pack to supply power to the energy harvesting management circuit board and the route management circuit board. The energy harvesting management circuit board sends a charging signal to the route management circuit board and controls the solar panel and the energy storage pack to charge the lawnmower together. If the power of the solar panel is less than the power value W1, and the power of the energy storage pack is greater than or equal to the power value U1, the energy harvesting management circuit board sends a charging signal to the route management circuit board and controls the energy storage pack to charge the lawnmower and supply power to the energy harvesting management circuit board and the route management circuit board. If the energy storage pack's power is less than the power value U1, and the solar panel's power is greater than or equal to the power value W1, the energy harvesting management circuit board sends a charging signal to the route management circuit board and controls the solar panel to charge the energy storage pack and lawnmower, and to supply power to the energy harvesting management circuit board and the route management circuit board.
[0010] Preferably, in the above-described intelligent lawnmower photovoltaic charging device, the energy harvesting management circuit board is provided with a power value U2, which is less than the power value U1. If the power of the solar panel is less than the power value W1 and the power of the energy storage pack is less than the power value U2, the energy harvesting management circuit board sends a return-to-base sleep signal to the route management circuit board. The route management circuit board converts the received return-to-base sleep signal into a boundary signal for the lawnmower to identify and return to the stop room for sleep. If the energy harvesting management circuit board detects again that the power of the solar panel is greater than or equal to the power value W1, the energy harvesting management circuit board controls the solar panel to charge the energy storage pack and lawnmower.
[0011] This utility model has the following beneficial effects: 1. The energy harvesting management circuit board can intelligently adjust the charging status of the solar panels and energy storage packs for the lawnmower based on their power levels. This allows the solar panels and energy storage packs to charge the lawnmower individually or together, adapting to different situations and improving the lawnmower's charging efficiency. This avoids situations where the lawnmower is left unattended due to insufficient charging and requires manual intervention. When the lawnmower is fully charged, the solar panels can charge the energy storage pack, maximizing the collection and utilization of photovoltaic-converted green energy and saving energy.
[0012] 2. When the solar panels cannot generate enough electricity to maintain the operation of the photovoltaic station and charging pile, the energy storage pack can provide enough electricity to keep the entire system running normally. When the energy storage pack's power drops to the power value U2, the energy harvesting management circuit board, in conjunction with the charging pile, can promptly notify the lawnmower to return to its dormant state. Once sunlight recovers and the solar panels can generate enough electricity, the solar panels can charge the energy harvesting management circuit board and the route management circuit board. The photovoltaic station and charging pile can then be woken up by the energy harvesting management circuit board, which can then charge the lawnmower and the energy storage pack to allow the lawnmower to resume normal operation. This avoids the entire photovoltaic station and charging pile system from shutting down due to depleted power, requiring manual intervention to resume operation after shutdown.

Detailed Implementation
[0015] The following is in conjunction with the appendix Figure 1-3 The following detailed description of the specific embodiments further illustrates the utility model, but these are not intended to limit the utility model: Example
[0016] like Figures 1-3 As shown, a smart lawnmower photovoltaic charging device includes a photovoltaic station 1 and a charging pile 2. The photovoltaic station 1 includes a shell 10, a solar panel 11, an energy storage pack 12, an energy harvesting management circuit board 13, and a connecting cable 14. The photovoltaic station 1 is electrically connected to the charging pile 2 through the connecting cable 14. The energy storage pack 12 and the energy harvesting management circuit board 13 are disposed inside the shell 10. The energy harvesting management circuit board 13 is electrically connected to the solar panel 11 through the connecting cable 14, and the energy storage pack 12 is electrically connected to the energy harvesting management circuit board 13. The energy harvesting management circuit board 13 is used to detect the power status of the solar panel 11 and the energy storage pack 12 and control the solar panel 11 and the energy storage pack 12 to charge the lawnmower, or control the solar panel 11 to charge the energy storage pack 12; the energy harvesting management circuit board 13 controls the charging pile 2 to send out a boundary signal for the lawnmower to recognize according to the power status of the solar panel 11 and the energy storage pack 12.
[0017] Preferably, the charging pile 2 has a parking chamber 21 for parking lawnmowers, a route management circuit board 22 and a boundary line 23. The boundary line 23 is set at the boundary of the site. The route management circuit board 22 is electrically connected to the boundary line 23 and determines the boundary range according to the boundary line 23, and sends a boundary signal for lawnmowers to identify.
[0018] Specifically, in this embodiment, the lawnmower has charging contacts, and the charging station 2 has charging terminals that cooperate with the charging contacts. When the lawnmower returns to the parking room 21 and the charging contacts are connected to the charging terminals, the energy harvesting management circuit board 13 can control the solar panel 11 and the energy storage pack 12 to charge the lawnmower separately or the solar panel 11 and the energy storage pack 12 to charge the lawnmower together.
[0019] Preferably, the energy harvesting management circuit board 13 sends a charging signal or a return-to-base sleep signal to the route management circuit board 22 according to the power status of the solar panel 11 and the energy storage pack 12. The route management circuit board 22 converts the received charging signal or return-to-base sleep signal into a boundary signal for the lawnmower to identify and return to the base for charging or sleep. The boundary signal is formed by the route management circuit board 22 regularly opening or closing the boundary line 23.
[0020] Preferably, the energy harvesting management circuit board 13 controls the solar panel 11 or the energy storage pack 12 to supply power to the energy harvesting management circuit board 13 and the route management circuit board 22.
[0021] Specifically, the energy harvesting management circuit board 13 is electrically connected to the solar panel 11 via the connecting cable 14, the energy storage pack 12 is electrically connected to the energy harvesting management circuit board 13 via the wiring harness built into the housing 10, and the route management circuit board 22 is electrically connected to the energy harvesting management circuit board 13 via the connecting cable 14. The energy harvesting management circuit board 13 controls the solar panel 11 or the energy storage pack 12 to supply power to the energy harvesting management circuit board 13 and the route management circuit board 22, thus eliminating the need for an additional power supply structure to supply power to the energy harvesting management circuit board 13 and the route management circuit board 22.
[0022] Preferably, the energy harvesting management circuit board 13 is provided with a power value W1 and a power value U1. The energy harvesting management circuit board 13 monitors the power status of the solar panel 11 and the energy storage pack 12 and compares it with the power value W1 and the power value U1. If the power of the solar panel 11 is greater than or equal to the power value W1, and the power of the energy storage pack 12 is greater than or equal to the power value U1, the energy harvesting management circuit board 13 controls the solar panel 11 or the energy storage pack 12 to supply power to the energy harvesting management circuit board 13 and the route management circuit board 22. The energy harvesting management circuit board 13 sends a charging signal to the route management circuit board 22 and controls the solar panel 11 and the energy storage pack 12 to charge the lawnmower together. If the power of the solar panel 11 is less than the power value W1, and the power of the energy storage pack 12 is greater than or equal to the power value U1, the energy harvesting management circuit board 13 sends a charging signal to the route management circuit board 22 and controls the energy storage pack 12 to charge the lawnmower and supply power to the energy harvesting management circuit board 13 and the route management circuit board 22. If the power of the energy storage pack 12 is less than the power value U1, and the power of the solar panel 11 is greater than or equal to the power value W1, the energy harvesting management circuit board 13 sends a charging signal to the route management circuit board 22 and controls the solar panel 11 to charge the energy storage pack 12 and the lawnmower, and to supply power to the energy harvesting management circuit board 13 and the route management circuit board 22.
[0023] Preferably, the energy harvesting management circuit board 13 is provided with a power value U2, which is less than the power value U1. If the power of the solar panel 11 is less than the power value W1 and the power of the energy storage pack 12 is less than the power value U2, the energy harvesting management circuit board 13 sends a return-to-base sleep signal to the route management circuit board 22. The route management circuit board 22 converts the received return-to-base sleep signal into a boundary signal for the lawnmower to identify and return to the parking room 21 for sleep. If the energy harvesting management circuit board 13 detects again that the power of the solar panel 11 is greater than or equal to the power value W1, the energy harvesting management circuit board 13 controls the solar panel 11 to charge the energy storage pack 12 and the lawnmower.
[0024] Specifically, the lawnmower has a built-in chip that can detect and control the lawnmower's battery level and operating status. The specific steps for charging the lawnmower are as follows: S1, the energy harvesting management circuit board 13 monitors the power status of the solar panel 11 and the energy storage pack 12 and compares it with the power value W1, the power value U1, and the power value U2; If the power of the solar panel 11 is greater than or equal to the power value W1, and the power of the energy storage pack 12 is greater than or equal to the power value U1, then proceed to step S2. If the power of the solar panel 11 is less than the power value W1, and the power of the energy storage pack 12 is greater than or equal to the power value U2, then proceed to step S3. If the power of the solar panel 11 is less than the power value W1, and the power of the energy storage pack 12 is less than the power value U2, then proceed to step S4. S2. The energy harvesting management circuit board 13 continuously sends a charging signal to the charging pile 2. The charging pile 2 converts the charging signal into a boundary signal for the lawnmower to recognize. If the lawnmower's battery level is below 50%, the lawnmower returns to the parking chamber 21 after recognizing the boundary signal. When the energy harvesting management circuit board 13 detects that the lawnmower is parked in the parking chamber 21, it controls the energy storage pack 12 and the solar panel 11 to charge the lawnmower at high power at the same time. When the lawnmower is fully charged, it will automatically leave the pile to mow the grass. The energy harvesting management circuit board 13 controls the solar panel 11 to charge the energy storage pack 12 to store energy. S3. The energy harvesting management circuit board 13 continuously sends a charging signal to the charging pile 2. The charging pile 2 converts the charging signal into a boundary signal for the lawnmower to recognize. If the lawnmower's power is below 50%, the lawnmower returns to the parking room 21 after recognizing the boundary signal. When the energy harvesting management circuit board 13 detects that the lawnmower is parked in the parking room 21, it controls the energy storage pack 12 to charge the lawnmower. S4. The energy harvesting management circuit board 13 continuously sends a return-to-base sleep signal to the charging pile 2. The charging pile 2 converts the return-to-base sleep signal into a boundary signal for the lawnmower to recognize. If the lawnmower's battery level is greater than or equal to 50%, it continues to work. Otherwise, the lawnmower returns to the parking chamber 21 of the charging pile 2 to sleep, avoiding power depletion and shutdown. When the energy harvesting management circuit board 13 detects that the power of the solar panel 11 is greater than or equal to the power value W1 and gradually increases, the energy harvesting management circuit board 13 controls the solar panel 11 to charge the lawnmower. When the lawnmower is working away from the charging pile, the energy harvesting management circuit board 13 controls the solar panel 11 to charge the energy storage pack 12.
[0025] The above structure allows for intelligent adjustment of the charging status of the solar panel 11 and energy storage pack 12 on the lawnmower based on their respective power levels. This means that the solar panel 11 and energy storage pack 12 can charge the lawnmower individually or together, adapting to different situations and improving the lawnmower's charging efficiency. This prevents the lawnmower from being left unattended due to insufficient charging and requiring manual intervention. When the lawnmower is fully charged, the solar panel 11 can charge and store energy in the energy storage pack 12, thereby maximizing the collection and utilization of photovoltaic-converted green energy and saving energy.
[0026] When the solar panel 11 cannot generate enough electricity to maintain the operation of the photovoltaic station 1 and the charging pile 2, the energy storage pack 12 can provide the normal operation of the entire system. When the power of the energy storage pack 12 drops to the power value U2, the energy harvesting management circuit board 13, in conjunction with the charging pile 2, can promptly notify the lawnmower to return to the charging pile and go into sleep mode. When the sunlight recovers and the solar panel 11 can generate enough electricity, the solar panel 11 can charge the energy harvesting management circuit board 13 and the route management circuit board 22. The photovoltaic station 1 and the charging pile 2 can be woken up by the energy harvesting management circuit board 13, and then the lawnmower and the energy storage pack 12 can be charged so that the lawnmower can resume normal operation. This avoids the situation where the entire system of the photovoltaic station 1 and the charging pile 2 shuts down due to the depletion of power, and requires human intervention to work after shutdown.
[0027] In summary, the above description is only a preferred embodiment of the utility model. All equivalent changes and modifications made within the scope of the utility model patent application should be included in the scope of the utility model.
