DETAILED DESCRIPTION
[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0024] In this disclosure, unless otherwise stated, the directional words used, such as "up, down, left, right", generally refer to the use status of the photovoltaic cleaning robot, and "inside, outside" refer to the outline of the parts themselves. In addition, the terms "first", "second", etc. used in this utility model are to distinguish one element from another, and do not have order and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0025] like Figure 1-Figure 4As shown, the present disclosure provides a photovoltaic cleaning robot, comprising: a battery assembly 1 and a conductive assembly 2, wherein the battery assembly 1 provides electrical energy to the photovoltaic cleaning robot so that the photovoltaic cleaning robot can move and clean the photovoltaic panel; the conductive assembly 2 connects the battery assembly 1 with an external power supply, so as to facilitate charging of the battery assembly 1 through the conductive assembly 2 by the external power supply, the external power supply can be a storage battery or a power grid, the conductive assembly 2 includes two conductive connection structures 3, one of the two conductive connection structures 3 connects the external power supply with the positive electrode of the battery assembly 1, and the other connects the external power supply with the negative electrode of the battery assembly 1, the conductive connection structure 3 includes a first conductive member 31 and a second conductive member 32 arranged at intervals, the first conductive member 31 is connected to the battery assembly 1, the second conductive member 32 is configured to be able to abut against the first conductive member 31 after deformation, and the second conductive member 32 is connected to the external power supply.
[0026] Through the above technical scheme, the external power supply is connected to the battery assembly 1 through the two conductive connection structures 3 in the conductive assembly 2, the first conductive member 31 in the conductive connection structure 3 is connected to the battery assembly 1, and the second conductive member 32 in the conductive connection structure 3 is connected to the external power supply, the first conductive member 31 and the second conductive member 32 are arranged at intervals, and the second conductive member 32 is configured to be deformed by heat and abut against the first conductive member 31. In this way, in the winter environment with a low temperature below -40°C and encountering snowy or icy scenes, when it is necessary to charge the battery assembly 1 through an external power supply, the second conductive member 32 is heated to melt the ice and snow between the second conductive member 32 and the first conductive member 31, and the second conductive member 32 is deformed by heat and abuts against the first conductive member 31, so that the conductive assembly 2 is turned on, and the external power supply can be electrically connected to the battery assembly 1 through the conductive assembly 2, so that the photovoltaic cleaning robot can be charged through an external power supply in a low temperature rainy and snowy environment.
[0027] It should be noted that the above-mentioned photovoltaic cleaning robot also includes a navigation system and a cleaning component 5, and cleans the photovoltaic components. For example, the navigation system may include a controller and multiple camera components. The real-time image of the photovoltaic component to be cleaned is obtained through the camera component. The controller plans the movement trajectory and cleaning intensity of the photovoltaic cleaning robot according to the obtained image. The cleaning component 5 includes a cleaning shaft, a cleaning brush and a water spray pipe. The above-mentioned navigation system and cleaning components are conventional technologies in the field, and the detailed structure will not be repeated in this disclosure.
[0028] In order to facilitate charging of the battery assembly 1 in a variety of ways, in some feasible ways, the battery assembly 1 includes a battery 11, a solar panel 12 and an inverter connecting the solar panel 12 and the battery 11, and the battery 11 is provided with an electrical connection point connected to the conductive connection structure 3. Therefore, in this embodiment, the battery 11 in the battery assembly 1 can be charged in two ways. One is that the solar panel 12 converts light energy into electrical energy under sufficient light and charges the battery 11 through the inverter. The battery 11 can be a lithium battery. The other is to charge the battery 11 in the battery assembly 1 through an external power supply through the second conductive member 32.
[0029] In order to facilitate heating and deforming the second conductive member 32, in some practicable ways, the second conductive member 32 includes a first conductive sheet 321 that can be deformed by heat and a heating sheet 322 connected to the first conductive sheet 321. The first conductive sheet 321 can be made of spring steel. The heating sheet 322 is connected to an external power source. The heating sheet 322 is used to heat the first conductive sheet. When the heating sheet 322 is heated to a preset temperature range, the first conductive sheet 321 is deformed by heat. The deformed first conductive sheet 321 abuts against the first conductive member 31, thereby realizing the conduction of the conductive component 2. The external power source can charge the storage battery 11 in the battery assembly 1 through the conductive component 2. Of course, when the heating sheet 322 stops working, the first conductive sheet 321 recovers as the temperature decreases. At this time, the first conductive sheet 321 is disconnected from the first conductive member 31.
[0030] In order to quickly heat the first conductive sheet 321 to deform it due to heat, in some practicable embodiments, there are multiple heating sheets 322, and the multiple heating sheets 322 are arranged at intervals along the first direction. In this embodiment, the first direction can refer to Figure 3 The X in the middle points to a direction, that is, the first direction is the width direction of the first conductive sheet 321, such as Figure 3 As shown, there are two heating plates 322 and they are spaced apart in the first direction. Both heating plates 322 are connected to an external power source. Thus, when the first conductive plate 321 needs to be heated, one heating plate 322 or two heating plates 322 can be started to heat simultaneously as required, thereby melting ice and snow at the first conductive plate 321 and the heating plate 322, and causing the first conductive plate 321 to deform due to heat and abut against the first conductive member 31, thereby realizing electrical connection between the external power source and the battery 11 in the battery assembly 1 through the conductive assembly 2, thereby enabling the battery 11 to be charged through the external power source.
[0031] In some embodied embodiments, the photovoltaic cleaning robot includes a support 4, which includes a plurality of mounting positions, wherein at least one mounting position is used to mount a battery assembly 1, and at least one mounting position is used to mount a conductive assembly 2. To facilitate the installation of the second conductive member 32, the second conductive member 32 also includes a first insulating seat 323. The first insulating seat 323 may be an epoxy resin insulating board. A mounting hole is provided on the first insulating seat 323. A fastener passes through the mounting hole to fix the first insulating seat 323 to the support 4. The fastener here may be an insulating screw. The first conductive sheet 321 includes a fixing portion 324 and a deformation portion 325. The fixing portion 324 is mounted on the first insulating seat 323 and is connected to an external power supply. The deformation portion 325 is connected to the first conductive member 31 after deformation.
[0032] Specifically, Figure 3 and Figure 4 As shown, the fixing portion 324 includes a horizontal connecting section 326 and an inclined connecting section 327. The horizontal connecting section 326 is fixed on the first insulating seat 323 and part of the horizontal connecting section 326 extends out of the first insulating seat 323 in the direction of the first conductive member 31. The inclined connecting section 327 is integrally formed with the horizontal connecting section 326. The inclined connecting section 327 is vertically inclined upward from a horizontal plane around the connecting point between the horizontal connecting section 326 and the inclined connecting section 327 as the axis, thereby shortening the distance between the first conductive member 31. In order to facilitate the processing and forming of the fixing portion 324 and the cooperation with the deformation portion 325, the angle between the inclined connecting section 327 and the horizontal connecting section 326 is an acute angle.
[0033] In addition, the deformation portion 325 may include a deformation segment 328 connected to the inclined connecting segment 327, and the deformation segment 328 is a deformation segment 328 having one end fixedly connected to the inclined connecting segment 327. In the present embodiment, the deformation segment 328 may be fixedly connected to the inclined connecting segment 327 by welding, and the deformation segment 328 is arranged in a "J" shape, with the "J"-shaped protruding portion of the deformation segment 328 facing the first conductive member 31, and the heating plate 322 is disposed in the recessed portion 329 of the deformation segment 328. Thus, when the heating plate 322 is powered on and heated, the deformation portion 325 can be deformed by heat and connected to the first conductive member 31, thereby facilitating charging of the battery 11 by an external power source.
[0034] In some embodied embodiments, the first conductive member 31 includes a second insulating seat 311 and a second conductive sheet 312, wherein the second insulating seat 311 may also be an epoxy resin insulating plate, and a plurality of mounting holes are provided on the second insulating seat 311, and fasteners pass through the mounting holes to mount the second insulating seat 311 on the support 4, and the second conductive sheet 312 is disposed on the second insulating seat 311, and the second conductive sheet 312 is electrically connected to the battery assembly 1.
[0035] In order to facilitate the electrical connection between the second conductive sheet 312 and the battery assembly 1, in some feasible embodiments, a through hole 313 is provided in the middle of the second insulating seat 311, and a conductive column 314 connected to the second conductive sheet 312 is provided in the through hole 313, and the conductive column 314 is electrically connected to the battery assembly 1, so that the second conductive sheet 312 is electrically connected to the battery assembly 1 through the conductive column 314.
[0036] In order to facilitate the first conductive sheet 321 to contact the second conductive sheet 312 after deformation, in some feasible methods, the cross-section of the second conductive sheet 312 is U-shaped. The U-shaped second conductive sheet 312 is convenient for fixing to the second insulating seat 311, and can also form a larger contact surface to contact the first conductive sheet 321, so that the first conductive sheet 321 and the second conductive sheet 312 are connected by surface contact, thereby making the electrical connection between the first conductive sheet 321 and the second conductive sheet 312 more stable.

In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0039] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
