Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solar energy industry, and particularly relates to a special charging mechanism for a photovoltaic cleaning robot. BACKGROUND

[0002] As a key component of modern smart home systems, the application of the sweeping robot in daily life is becoming more and more widespread. With the popularization of household intelligent appliances, the frequency of use of the sweeping robot has significantly increased. According to relevant data, the number of times of use per week in some families can reach 3-5 times or even more. After each use of the sweeping robot, the sweeping robot needs to rely on a special charging device for power supply to ensure sufficient power for the next use.

[0003] For example, the application number CN202220422499.5 relates to a charging device and a cleaning robot system. The charging device is used in cooperation with the cleaning robot. The charging device includes a charging device main body and a moisture-proof pad. The charging device main body includes a horizontally extending platform and a pair of charging poles arranged on the platform. The front end of the platform forms a first splicing edge. The pair of charging poles is used to charge the cleaning robot. The moisture-proof pad is detachably connected with the platform. The moisture-proof pad forms a second splicing edge. The first splicing edge and the second splicing edge are arranged in alignment. The moisture-proof pad is used to carry the cleaning robot. By arranging the charging device main body and the moisture-proof pad that can be detachably connected with each other, the problem that wet cleaning parts easily cause water accumulation on the ground when the cleaning robot is parked on the charging device can be solved. The problem that the moisture-proof pad cannot be easily detached or is inconvenient to detach, so that the user cannot clean the moisture-proof pad alone, can also be solved. The user experience is improved.

[0004] However, there are some deficiencies in the design of the current charging mechanism of the cleaning robot.

[0005] Firstly, the exposed electrodes of the charging device are directly exposed to the external environment in the non-charging state. Not only are they prone to damage due to bumps and corrosion, and there is a risk of electric shock, but dust and other impurities in the outdoor environment are also easily attached to the surface of the electrodes, affecting the conductivity. Therefore, due to the lack of effective protection structure, the safety and durability of the electrode plates in the non-charging state are poor.

[0006] Secondly, the power supply mode of the charging device is single and lacks adaptability. The traditional charging mechanism relies on the charging port of the external power supply for direct power supply. When the external power supply fails, the normal charging needs of the robot cannot be guaranteed. At the same time, it cannot automatically switch the power supply mode under light conditions, and cannot effectively utilize solar energy resources, which does not meet the design concept of energy saving and consumption reduction.

During the forward movement of the wedge-shaped push block (3), it contacts the bottom of the lifting plate (5) and... The lifting plate (5) is pushed upwards. When the lifting plate (5) rises, the electrode plate (501) at its upper end adheres to the bottom of the wedge-shaped side blocks (401) on both sides of the sliding plate (4) and pushes the side blocks (401), causing the sliding plate (4) to slide backwards in the bottom groove (106). The side blocks (401) move away from the connecting groove (1061), and the electrode plate (501) extends out of the bottom groove (106) through the connecting groove (1061) and contacts the charging and discharging area of ​​the robot. At this time, the electrode plate (501) is electrically connected to the battery (1021) or charging port (1011) in the pile body (1) to start charging the robot.

2. The dedicated charging mechanism for a photovoltaic cleaning robot according to claim 1, characterized in that: The pile body (1) has a through-type movable groove (101) on the inner side of the upper end, and a charging port (1011) is provided on the bottom side of the pile body (1).

3. A dedicated charging mechanism for a photovoltaic cleaning robot according to claim 2, characterized in that: A rectangular inner groove (102) is provided in the middle of the pile body (1). A storage battery (1021) is installed in the inner groove (102). Through-type heat dissipation holes are distributed at equal intervals at both ends of the inner groove (102). When the storage battery (1021) has sufficient power, it can supply power to the electrode plate (501). When the storage battery (1021) has low power, it can automatically switch to supply power to the electrode plate (501) through the charging port (1011). A photosensitive battery (103) is installed on the top of the pile body (1). An electromagnetic block (1031) is installed at the upper end of the inner groove (102). The start-up of the electromagnetic block (1031) is controlled by the photosensitive battery (103). The electromagnetic block (1031) is powered by the storage battery (1021).

4. A dedicated charging mechanism for a photovoltaic cleaning robot according to claim 3, characterized in that: The pile body (1) has flaps (104) mounted on both ends by means of coil springs. A photovoltaic panel (1041) is fixedly mounted on the outer end of the flap (104). When the flap (104) is unfolded, the photovoltaic panel (1041) can supply power to the battery (1021).

5. A dedicated charging mechanism for a photovoltaic cleaning robot according to claim 4, characterized in that: A cover plate (105) is slidably installed in the inner groove (102) by means of a spring. The two ends of the cover plate (105) cover the outside of the flip plate (104). When the cover plate (105) rises, the flip plate (104) flips and unfolds to both sides. A fixing block (1051) is installed at the middle position of the upper end of the cover plate (105). When the electromagnetic block (1031) is energized, the fixing block (1051) and the electromagnetic block (1031) are magnetically connected.

6. A dedicated charging mechanism for a photovoltaic cleaning robot according to claim 1, characterized in that: The lifting plate (5) has a rectangular structure, and two sets of electrode plates (501) are provided on both sides of the upper end of the lifting plate (5).
