[0002] Existing photovoltaic cleaning robots mostly use contact-based power supply, and the contact charging mechanism is generally used exposed. When the charging electrode plates are used exposed outdoors, the following problems are prone to occur: First, when using metal electrode plates (such as stainless steel, copper, etc.), electrochemical reactions are particularly prone to occur during outdoor charging, causing the electrode plate surface to rust, thereby causing charging failure; second, when using non-metallic electrode plates (such as carbon brushes) in high salt fog and high humidity scenes such as coastal areas, they are prone to galvanic cell reactions, electrochemical reactions, etc., producing and depositing weakly conductive or non-conductive metal oxides, or destroying the bonding components inside the carbon brush, causing the carbon brush to powder and fall off, thereby causing charging failure; when used in high-dust environments such as deserts, dust will also be deposited on the surface of the electrode plates, especially on rainy days or at night with high humidity.

[0058] The core of the utility model is to provide a charging system for a photovoltaic cleaning robot to solve the problem that the charging system of the photovoltaic cleaning robot is easily affected by the external environment during the charging process, resulting in charging failure.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0060] Reference Figures 1-6 As shown, the utility model provides a charging system for a photovoltaic cleaning robot, comprising a first charging component 1 and a second charging component 2, wherein the first charging component 1 comprises a moving mechanism 11 arranged on the cleaning robot and a first charging pole 12 arranged on the moving mechanism 11 and connected to a battery module on the cleaning robot; the second charging component 2 comprises an open shell 21 arranged at a preset charging position and a second charging pole 22 arranged in the open shell 21 and connected to a power supply device, the opening direction of the open shell 21 is downward or toward the side, and the downward and toward the side here are both based on the cleaning robot; when the cleaning robot moves to the preset charging position, that is, Figure 4 The first charging pole 12 is shown in a position facing the open shell 21. At that time, the moving mechanism 11 can drive the first charging pole 12 to move into the open shell 21 through telescopic movement and contact with the second charging pole 22 to achieve charging connection.

[0061] The charging system of the photovoltaic cleaning robot, in actual application, when the cleaning robot needs to be charged, the cleaning robot is controlled to move to a preset charging position, and the first charging pole 12 thereon is driven by the moving mechanism 11 to move into the open shell 21 and contact with the second charging pole 22 to realize charging connection. Since the first charging pole 12 is connected to the battery module on the cleaning robot, and the second charging pole 22 is connected to the power supply device, the power supply device can charge the battery module. It is important that since the first charging pole 12 and the second charging pole 22 are in contact inside the open shell 21, and the opening direction of the open shell 21 is downward or toward the side, the first charging pole 12 and the second charging pole 21 in the charging state can be charged to a certain extent. The protection effectively reduces the interference of external environmental factors such as dust or rain, and then reduces the probability of charging failure of the charging system due to the influence of the external environment, that is, to a certain extent, solves the problem that the charging system is easily affected by the external environment during the charging process and causes charging failure; in addition, since the moving mechanism 11 can drive the first charging pole 12 to move into the open shell cover 21 and contact the second charging pole 22, therefore, when there is a non-conductive material on the contact surface between the first charging pole 12 and the second charging pole 22, the first charging pole 12 can be repeatedly driven by the moving mechanism to perform telescopic movement, so that the first charging pole 12 and the second charging pole 22 rub back and forth in a straight line, thereby erasing the non-conductive material, and more effectively ensuring the reliability of charging.

[0062] It should be noted that the first charging assembly 1 can be specifically positioned below the frame of the cleaning robot and near the side of the frame. This structural design facilitates the alignment between the first charging electrode 12 of the first charging assembly 1 and the second charging electrode 22 of the second charging assembly 2. Of course, it is understood that in actual applications, the first charging assembly 1 can also be designed in other locations based on actual needs, and no specific restrictions are given here. It should also be noted that the downward opening of the open shell 21 is one of the preferred embodiments of the present invention. This arrangement allows the first charging electrode 12 to extend from the bottom of the open shell 21, effectively preventing rainwater or dust from reaching the contact point between the first charging electrode 12 and the second charging electrode 22, thereby providing better protection. Of course, when the open shell 21 is positioned sideways, that is, toward the side of the cleaning robot, the first charging electrode 12 and the second charging electrode 22 can be aligned horizontally, which also provides a certain degree of dust and water protection.

[0063] It should also be noted that the above-mentioned preset charging position may specifically include a first charging position and / or a second charging position, wherein the first charging position is constructed as a first preset position on the parking platform, so that the cleaning robot can be charged when it moves to the parking platform; the second charging position is constructed as a second preset position on the walking path of the cleaning robot on the photovoltaic module, so that the cleaning robot can intermittently perform charging operations during the cleaning process.

[0064] In some specific embodiments, reference Figure 1 , combined with Figure 4-Figure 6 As shown, the moving mechanism 11 may specifically include a guide rail 111, a sliding portion 112, and a driving mechanism 113. The guide rail 111 is disposed on the frame of the cleaning robot; the sliding portion 112 is disposed on the guide rail 111 and is capable of sliding along the guide rail 111; the driving mechanism 113 is used to drive the sliding portion 112 to slide along the guide rail 111; and the first charging electrode 12 is disposed on the sliding portion 112. Therefore, by driving the sliding portion 112 along the guide rail, the driving mechanism 113 can drive the first charging electrode 12 on the sliding portion 112 to perform linear telescopic motion. This structure is very simple and easy to manufacture. It should be noted that the specific structural form of the driving mechanism 113 may include, but is not limited to, using a drive motor to drive a lead screw to rotate, causing the sliding portion 112 disposed on the lead screw to perform linear reciprocating motion. For example, the driving mechanism 113 may also be designed as other drive structures, such as a linear drive motor, an electric linear actuator, or a cylinder drive, etc., which are not further limited herein.

[0065] In a further embodiment, referring to Figure 1 , combined with Figure 4-Figure 6 As shown, the sliding portion 112 may specifically include a slider 1121 slidably connected to the guide rail 111 and an insulating connecting plate 1122 provided on the slider 1121, and the first charging electrode 12 is provided on the insulating connecting plate 1122. By designing the above-mentioned structural form, the installation position of the first charging electrode 12 is more convenient to arrange. Among them, the insulating connecting plate 1122 can be specifically designed as an L-shaped insulating plate structure, one of which is fixedly connected to the slider 1121. The fixing method can be, but is not limited to, fastener connection. The other bent portion is used to fix the first charging electrode 12. The method of fixing the first charging electrode 12 to the insulating connecting plate 1122 can be, but is not limited to, fastener connection, snap connection, bonding, etc. For example, a corresponding mounting opening is designed on the insulating connecting plate 1122, and the root of the main body of the first charging electrode 12 is inserted into the mounting opening, and the insertion and fitting can be selected to be snap-fit connection, or bonding.

[0066] In some other specific embodiments, referring to Figure 1 , combined with Figure 4-Figure 6As shown, the insulating connecting plate 1122 can be specifically designed to be arranged opposite the open end of the open shell 21. By adopting this structural design, the first charging pole 12 can be designed as a plug-in structure, making the processing of the first charging pole 12 more convenient. In addition, when the first charging pole 12 and the second charging pole 22 are connected for charging, the insulating connecting plate 1122 and the open end of the open shell 21 are preferably designed to be sealed and adapted. Specifically, the insulating connecting plate 1122 and the open end of the open shell 21 can be sealed and adapted by an insulating seal 3. The insulating seal 3 can be specifically provided on the insulating connecting plate 1122 or designed at the open end of the open shell 21. In actual application, the configuration can be selected according to actual needs, as long as the sealing adaptation between the two can be achieved. No specific limitation is given here. By designing the insulating connecting plate 1122 and the open end of the open shell 21 as a sealed and adapted structure, the first charging pole 12 and the second charging pole 22 are placed in a relatively closed space after charging and connected, which can provide better protection.

[0067] In some other specific embodiments, referring to Figure 1 and Figure 4 As shown, when the insulating connecting plate 1122 is arranged opposite the open end of the open housing 21, a cable fixing member 1123 may be provided on the side of the insulating connecting plate 1122 facing away from the open housing 21. The connection cable of the first charging electrode 12 is fixed to the cable fixing member 1123. With this structural design, when the insulating connecting plate 1122 drives the first charging electrode 12 to move, the dynamic position of the connection cable is at the cable fixing member 1123, rather than at the base of the connection cable (the base is relatively weak and easily damaged), thereby helping to improve the stability and fatigue life of the connection between the connection cable and the first charging electrode 12.

[0068] It should be noted that, referring to Figure 1 、 Figure 2 and Figure 4-Figure 6 As shown, the first charging electrode 12 may specifically include an insulating carrier 121, a first positive contact 122 and a first negative contact 123. The insulating carrier 121 is provided on the moving mechanism 11 and can move with the moving mechanism 11. Its main function is to carry and install the first positive contact 122 and the first negative contact 123; the first positive contact 122 and the first negative contact 123 are provided on the insulating carrier 121 in an insulated manner from each other, and the two are respectively connected to the positive and negative poles corresponding to the battery module of the cleaning robot through wiring cables; refer to Figure 3 and Figure 4-Figure 6As shown, the second charging electrode 22 can specifically include a second positive electrode contact 221 and a second negative electrode contact 222 arranged in the open shell cover 21, and the second positive electrode contact 221 is used to adapt to the contact with the first positive electrode contact 122, and the second negative electrode contact 222 is used to adapt to the contact with the first negative electrode contact 123, wherein the second positive electrode contact 221 is connected to the positive electrode of the power supply device through the positive electrode lead-out cable 23, and the second negative electrode contact 222 is connected to the negative electrode of the power supply device through the negative electrode lead-out cable 24, and the corresponding lead-out positions of the positive electrode lead-out cable 23 and the negative electrode lead-out cable 24 on the open shell cover 21 can be fixed and sealed by, but not limited to, using a potting glue 25.

[0069] In some specific embodiments, reference Figures 1-6 As shown, the first positive contact member 122 and the first negative contact member 123 are preferably arranged opposite each other on the insulating support member 121, while the second positive contact member 221 and the second negative contact member 222 are arranged opposite each other on the inner circumferential wall of the open shell 21. This structural design improves the isolation and insulation between the positive and negative electrodes.

[0070] In a further embodiment, the first positive electrode contact 122 and the first negative electrode contact 123 are preferably configured as elastic contact structures disposed on the insulating support member 121. The specific structural form of the elastic contact structure can be, but is not limited to, designed as follows: corresponding sliding grooves are respectively designed on the two back surfaces of the insulating support member 121, and the roots of the first positive electrode contact 122 and the first negative electrode contact 123 are respectively slidably disposed in the corresponding sliding grooves, and elastic elements 123 are respectively disposed between the roots of the first positive electrode contact 122 and the first negative electrode contact 123 and the bottoms of the corresponding sliding grooves. In actual applications, other elastic contact structural forms can also be designed, and no specific limitations are given here.

[0071] In some other specific embodiments, the end of the insulating carrier 121 facing the open shell cover 21 is preferably constructed as a tapered guide structure, such as a structure similar to a cone. This design makes it easier for the insulating carrier 121 of the first charging pole 12 to extend into the open shell cover 21; in addition, a positioning groove 210 can be provided on the inner side of the closed end of the open shell cover 21, such as a structure similar to a waist hole, and the end of the insulating carrier 121 facing the open shell cover 21 is adapted to the positioning groove 210. By designing it into the above-mentioned structural form, after the insulating carrier 121 is extended into the open shell cover 21, the positioning groove 210 can play a certain limiting role on the insulating carrier 121.

[0072] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
