Description

Technical Field

[0001] This invention relates to the field of solar energy technology, and in particular to a dedicated charging mechanism for photovoltaic cleaning robots. Background Technology

[0002] As a key component of modern smart home systems, robotic vacuum cleaners are increasingly widely used in daily life. With the popularization of smart home appliances, the frequency of use of robotic vacuum cleaners has increased significantly. According to relevant statistics, some families use them 3-5 times a week or even more. After each use, robotic vacuum cleaners need to be recharged with a dedicated charging device to ensure sufficient power for the next use.

[0003] For example, application number CN202220422499.5 discloses a charging device and a cleaning robot system. The charging device is used to cooperate with the cleaning robot. The charging device includes a charging device body and a moisture-proof mat. The charging device body includes a horizontally extending platform and a pair of charging electrodes disposed on the platform. The front end of the platform forms a first splicing edge. The pair of charging electrodes are used to charge the cleaning robot. The moisture-proof mat is detachably connected to the platform. The moisture-proof mat forms a second splicing edge. The first splicing edge and the second splicing edge are aligned and spliced ​​together. The moisture-proof mat is used to support the cleaning robot. By setting the charging device body and the moisture-proof mat that can be detachably connected to each other, the problem of water accumulation on the ground caused by the wet cleaning parts when the cleaning robot is parked at the charging device can be solved. It also solves the problem that the moisture-proof mat is not detachable or is inconvenient to detach, which makes it impossible for users to clean the moisture-proof mat separately, thus improving the user experience.

[0004] However, there are some shortcomings in the current design of charging mechanisms for cleaning robots: First, the exposed electrodes of the charging device are directly exposed to the external environment when not charging. They are not only easily damaged by bumps and corrosion, posing a risk of leakage, but also dust and other impurities in the outdoor environment can easily adhere to the electrode surface, affecting conductivity. Therefore, due to the lack of an effective protective structure, the safety and durability of the electrode sheet are poor when not charging. Secondly, the power supply mode of the charging device is singular and lacks adaptability. Traditional charging mechanisms mostly rely on the charging port of an external power source for direct power supply. When the external power source fails, the normal charging needs of the robot cannot be guaranteed. At the same time, it fails to realize automatic switching of power supply mode under light conditions, and cannot effectively utilize solar energy resources, which does not conform to the design concept of energy conservation and consumption reduction. Summary of the Invention

[0005] To address the above problems, one objective of this invention is to overcome these shortcomings, and more specifically, to provide a dedicated charging mechanism for photovoltaic cleaning robots. This mechanism not only provides two power supply methods for the robot, effectively saving energy, but also protects the charging electrode plates.

[0006] In a first aspect, this invention provides a dedicated charging mechanism for a photovoltaic cleaning robot, specifically comprising: a pile body; the pile body is generally L-shaped, with a bottom groove inside the lower end of the pile body, and two sets of through-type connecting grooves symmetrically arranged at the upper end of the bottom groove; a contact plate is provided at the upper front side of the pile body, a toothed rod A at the outer end of the contact plate slides with the pile body, the toothed rod A penetrates the pile body, and the toothed rod A is connected to a gear in the bottom groove; a spring is provided between the contact plate and the pile body; and a pusher block is slidably arranged inside the bottom groove, the pusher block being able to move horizontally back and forth within the bottom groove. The sliding mechanism involves a toothed rod B at the outer end of the push block connected to a gear transmission. A sliding plate is slidably installed inside the upper part of the bottom groove via a spring. The sliding plate can slide horizontally back and forth within the bottom groove. The side block outside the sliding plate shields the connecting groove. A lifting plate is slidably installed inside the front side of the bottom groove via a spring. The lifting plate can slide vertically up and down within the bottom groove. The electrode plate on the lifting plate is in contact with the bottom of the side block, and the electrode plate can extend out of the connecting groove. When the push block moves forward, it can push the lifting plate up. The electrode plate can be electrically connected to the battery and charging port inside the pile.

[0007] Preferably, a through-type movable groove is provided on the inner side of the upper end of the pile body, and a charging port is provided on the bottom side of the pile body.

[0008] Preferably, a rectangular inner groove is provided in the middle of the pile body, and a storage battery is installed in the inner groove. Through-type heat dissipation holes are distributed at equal intervals at both ends of the inner groove. When the storage battery has sufficient power, it can supply power to the electrode plates. When the storage battery has low power, it can automatically switch to supply power to the electrode plates through the charging port. A photosensitive battery is installed on the top of the pile body, and an electromagnetic block is installed at the upper end of the inner groove. The activation of the electromagnetic block is controlled by the photosensitive battery, and the electromagnetic block is powered by the storage battery.

[0009] Preferably, both ends of the pile are equipped with flaps that are rotatably mounted by means of coil springs. A photovoltaic panel is fixedly mounted on the outer end of the flap. When the flap is unfolded, the photovoltaic panel can supply power to the battery.

[0010] Preferably, a cover plate is slidably installed in the inner groove by means of a spring. The two ends of the cover plate cover the outside of the flip plate. When the cover plate rises, the flip plate flips and unfolds to both sides. A fixing block is installed at the middle position of the upper end of the cover plate. When the electromagnetic block is energized, the fixing block is magnetically connected to the electromagnetic block.

[0011] Preferably, a rotating rod is rotatably mounted on the rear side of the bottom groove, and gears are fixedly mounted on both ends of the rotating rod.

[0012] Preferably, a rubber pad is provided on the front side of the contact plate, and toothed rods A are provided at both ends of the rear side of the contact plate.

[0013] Preferably, the push block has a wedge-shaped structure, and two sets of toothed rods B are fixedly installed on both sides of the rear end of the push block.

[0014] Preferably, the sliding plate has a rectangular structure, and side blocks are fixedly installed at the lower ends of both sides of the sliding plate, wherein the side blocks have a wedge-shaped structure.

[0015] Preferably, the lifting plate has a rectangular structure, and two sets of electrode plates are provided on both sides of the upper end of the lifting plate.

[0016] This invention provides a dedicated charging mechanism for photovoltaic cleaning robots, which has the following beneficial effects: 1. In this invention, by setting up a contact plate, gear transmission structure, push block, lifting plate and sliding plate and other linkage components, the dynamic protection function of the electrode sheet is realized. In the non-charging state, the electrode sheet is stored in the bottom groove, and the side block of the sliding plate shields the connecting groove, which can effectively prevent the electrode sheet from being directly exposed to the external environment, reduce the risk of damage caused by bumps and corrosion, and prevent dust from affecting the conductivity. When the sweeping robot approaches and pushes the contact plate, the push block moves forward to lift the lifting plate through the transmission action of the rack and gear, so that the electrode sheet extends out of the connecting groove and contacts the robot for charging. After charging is completed, the electrode sheet automatically retracts into the bottom groove and is shielded again by means of the spring reset mechanism. This structure realizes the automatic extension and protection of the electrode sheet through mechanical linkage, which significantly improves the safety and durability in the non-charging state and reduces the risk of leakage.

[0017] 2. In this invention, a multi-power supply mode of "photovoltaic panel + battery + external power supply" is innovatively adopted. Through the coordinated control of photosensitive battery and electromagnetic block, intelligent switching of power supply mode is realized. When the light intensity reaches the set threshold, the photosensitive battery triggers the electromagnetic block to work, adsorbing the cover plate to rise, causing the flaps on both sides of the pile to unfold under the action of coil springs. The photovoltaic panel receives solar energy and charges the battery. When the battery has sufficient power, it prioritizes powering the electrode plates. When the power is too low, it automatically switches to external power supply (charging port) to ensure that the robot's charging needs are not affected by a single power failure. In addition, when the flaps are unfolded, the light-receiving area of ​​the photovoltaic panel can be expanded to improve energy conversion efficiency. When idle, the cover plate resets to shield the flaps, reducing the risk of damage to the photovoltaic panel from impacts. This design not only adapts to different light conditions and power supply environments, but also makes full use of clean energy, which is in line with the design concept of energy saving and consumption reduction.

When the electromagnetic block 1031 is energized, the fixing block 1051 is magnetically connected to the electromagnetic block 1031; the inner groove 106... A rotating rod 107 is rotatably mounted on the rear side of the robot vacuum, and gears 1071 are fixedly mounted on both ends of the rotating rod 107.

A charging port 1011 is provided, which can supply power to the electrode plate 501 when the battery 1021 is low, thereby meeting the charging needs of the robot vacuum. A rectangular inner slot 102 is provided, through which the battery 1021 can pass. Installed inside the pile body 1; equipped with a storage battery 1021 to store electrical energy and power the sweeping robot; equipped with a photosensitive battery 103, which controls the electromagnetic block 1031 to start when the external light intensity reaches a certain level, and unfolds the flip plate 104, thereby enabling the photovoltaic panel 1041 to work; equipped with an electromagnetic block 1031, which, when energized, can attract the fixing block 1051 and move the cover plate 105 to the upper end; equipped with a flip plate 104, on which the photovoltaic panel 1041 can be installed; equipped with a photovoltaic panel 1041, which can convert solar energy into electrical energy and store it in the storage battery 1021;A cover plate 105 is provided. By covering the outside of the flap 104 with the cover plate 105, the flap 104 can be retracted to both sides of the pile body 1. When the cover plate 105 is raised, it loses its restraint on the flap 104 and allows the flap 104 to unfold at the outer end of the pile body 1. When the sides of the cover plate 105 are long enough, they can protect the photovoltaic panel 1041 installed at the outer end of the flap 104. A bottom groove 106 is provided, in which a lifting plate 5 with electrode plates 501 can be movably installed. A connecting groove 1061 is provided, allowing the electrode plates 501 to extend from the bottom groove 106 through the connecting groove 1061, thereby providing power to the sweeping robot. A rotating rod 107 is provided, on which a gear 1071 can be installed. The gear 1071 can be used for the transmission connection of the rack A201 and rack B301.

The cover plate 105 can protect the flip plate 104 and the photovoltaic panel 1041. When the light intensity reaches a certain level, the photosensitive cell 103 can control the screw to rotate, so that the cover plate 105 rises.

[0033] This invention features rotating flaps 104 with photovoltaic panels 1041 mounted at both ends of the pile body 1, and a cover plate 105 slidably mounted in the inner groove 102, which limits the flaps 104.

When the light intensity reaches a certain level, the photosensitive battery 103 controls the electromagnetic block 1031 to start, and through the magnetic attraction of the fixing block 1051, the cover plate 105 rises, causing the flaps 104 to drive the photovoltaic panels 1041 to unfold and work. After the flaps 104 are unfolded, the effect of receiving light can be improved. When the cover plate 105 is attached to both sides of the pile body 1, the photovoltaic panels 1041 can be stored, reducing the risk of damage from bumps. The invention also features two automatically switchable charging modes, a charging port 1011 and a battery 1021, which can meet the power supply needs of the sweeping robot in different environments and effectively save energy.

[0034] As a third embodiment of the present invention, based on embodiment 1, such as Figures 7 to 9As shown, a rubber pad is provided on the front side of the contact plate 2, and toothed rods A201 are provided at both ends of the rear side of the contact plate 2; the push block 3 has a wedge-shaped structure, and two sets of toothed rods B301 are fixedly installed on both sides of the rear end of the push block 3; the sliding plate 4 has a rectangular structure, and side blocks 401 are fixedly installed on the lower ends of both sides of the sliding plate 4, and the side blocks 401 have a wedge-shaped structure; 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; the contact plate 2 is provided so that when the sweeping robot moves to the front end of the pile 1, it can push the contact plate 2 and extend the electrode plates 501 to charge it; the toothed rods A201 are provided so that when the contact plate 2 moves, the toothed rods A201 can drive the gear 1071 to rotate; the push block 3 is provided so that the push block 3 can drive the gear 1071 to rotate. The forward movement can lift the lifting plate 5 and allow the electrode plate 501 to extend from the bottom groove 106; the rack B301 is provided so that when the gear 1071 rotates, it can drive the push block 3 to slide inside the bottom groove 106; the sliding plate 4 is provided, and side blocks 401 are provided at both ends of the sliding plate 4; the wedge-shaped side blocks 401 are provided so that the side blocks 401 can block the connecting groove 1061, and when charging, the electrode plate 501 can push the side blocks 401 aside and extend from the connecting groove 1061; the lifting plate 5 is provided, and two sets of electrode plates 501 are provided on the lifting plate 5; after the electrode plate 501 extends from the connecting groove 1061, it can be brought into contact with the charging and discharging area on the sweeping robot to achieve charging of the sweeping robot.

[0035] This invention involves sliding a lifting plate 5 with electrode plates 501 in the bottom groove 106 within the electrode plate 501. When the sweeping robot moves to the front of the charging station 1 for charging, it pushes the contact plate 2 to move. Under the transmission of the gear 1071, the push block 3 moves forward, lifting the lifting plate 5. After the robot moves to the corresponding position, the electrode plate 501 extends through the connecting groove 1061, thus achieving contact charging between the electrode plate 501 and the sweeping robot. After charging is complete, the sweeping robot leaves, the spring pushes the contact plate 2 to reset, causing the push block 3 to slide backward, and the lifting plate 5 to retract the electrode plate 501 back into the bottom groove 106, thereby protecting it.

[0036] The specific usage and function of this embodiment are as follows: In this invention, such as Figures 1 to 9As shown, when the sweeping robot needs charging, it moves to the front of the dock 1. The front end of the robot contacts the rubber pad on the front side of the contact plate 2 and pushes the contact plate 2 backward. The toothed rod A201 on the rear side of the contact plate 2 moves synchronously with the contact plate 2 and drives the gears 1071 at both ends of the rotating rod 107 in the bottom groove 106 to rotate. When the gears 1071 rotate, they mesh with the toothed rod B301 at the rear end of the push block 3, causing the push block 3 to slide forward in the bottom groove 106. During the forward movement of the wedge-shaped push block 3, it contacts the bottom of the lifting plate 5 and pushes the lifting plate 5 upward. When the lifting plate 5 rises, the electrode plate 501 at its upper end contacts the sides of the sliding plate 4. The wedge-shaped side block 401 is pushed and its bottom is attached, causing the sliding plate 4 to slide backward in the bottom groove 106. The side block 401 moves 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. During the charging process, if the external light intensity reaches the set value, the photosensitive battery 103 at the top of the pile body 1 controls the electromagnetic block 1031 at the upper end of the inner groove 102 to start. The electromagnetic block 1031 generates a magnetic force to attract the solid at the upper end of the cover plate 105. The fixed block 1051 causes the cover plate 105 to slide upward in the inner groove 102. The cover plate 105 is released from the limiting position of the flip plates 104 at both ends of the pile body 1. The flip plates 104 are flipped and unfolded to both sides under the action of the coil spring. After the photovoltaic panel 1041 at the outer end of the flip plate 104 unfolds, it receives solar energy and stores electrical energy in the storage battery 1021. When the storage battery 1021 has sufficient power, it prioritizes powering the electrode plate 501. If the storage battery 1021 has too low a power, it automatically switches to power supply from the charging port 1011. After the robot finishes charging, it moves away from the front of the pile body 1. The contact plate 2 is reset forward under the action of the spring. The rack A201 drives the gear 1. 071 rotates in the reverse direction, and the push block 3 slides backward and resets under the transmission of gear 1071 and rack B301. The lifting plate 5 moves downward under its own weight and the action of the spring. The electrode plate 501 retracts into the bottom groove 106. The sliding plate 4 slides backward and resets under the action of the spring. The side block 401 re-shiels the connecting groove 1061. At the same time, if the light intensity decreases, the photosensitive cell 103 controls the electromagnetic block 1031 to close. The cover plate 105 slides downward and resets under the action of the spring and covers the outside of the flip plate 104. The flip plate 104 rotates in the reverse direction and is stored on both sides of the pile body 1 under the pressure of the cover plate 105. The photovoltaic panel 1041 stops working.
