Description

Technical Field

[0001] This application belongs to the field of photovoltaic cleaning robot technology, and particularly relates to a mounting bracket and a photovoltaic cleaning robot. Background Technology

[0002] In photovoltaic (PV) cleaning robots, the cleaning unit is typically connected to the main unit via a mounting bracket. When the robot is performing cleaning tasks, the cleaning unit is susceptible to external forces such as unevenness of the PV panel surface, frame collisions, or impacts from obstacles, causing the mounting bracket to bear unexpected impact loads. Related technologies often use rigid connections such as screws to secure the cleaning unit to the main unit. However, such fixed mounting brackets are prone to breakage under impact loads, causing the cleaning unit to accidentally detach from the main unit. Furthermore, the assembly process is cumbersome and inconvenient, affecting the robot's normal operation and cleaning efficiency. Utility Model Content

Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] The following is for reference. Figures 1-4 The present application describes a photovoltaic cleaning robot 1 and a mounting bracket 10 according to embodiments thereof.

[0024] like Figure 1 and Figure 2 As shown, the photovoltaic cleaning robot 1 includes a cleaning unit 20, a mounting bracket 10, and a main unit 30. It can perform tasks such as removing dust, snow, and other obstructions from the surface of photovoltaic panels to ensure power generation efficiency.

[0025] The cleaning unit 20 can come into contact with the surface of the photovoltaic panel to perform physical cleaning. The cleaning unit 20 can be a roller brush, mop, etc.

[0026] like Figures 1-4 As shown, the mounting bracket 10 is used to mount the cleaning unit 20 onto the main unit 30. The relevant structure of the mounting bracket 10 and its assembly method with the main unit 30 will be described in detail below.

[0027] like Figure 1 and Figure 2 As shown, the host 30 can command and coordinate the operation of the photovoltaic cleaning robot 1, including structures such as the first support rod 301 and the second support rod 302. The relationship between the various components of the host 30 will be described in detail below.

[0028] This application also provides a mounting bracket 10.

[0029] Mounting bracket 10 can be manufactured through precision casting, injection molding, or other processes.

[0030] like Figures 1-4 As shown, the mounting bracket 10 has a first mounting groove 11, a second mounting groove 12, and a first mounting structure 131 for connecting the cleaning unit 20.

[0031] like Figures 1-4As shown, the first mounting structure 131 is located on the side of the first mounting groove 11 opposite to the second mounting groove 12, that is, the first mounting groove 11 is located between the first mounting structure 131 and the second mounting groove 12. The first mounting structure 131 can be a threaded hole, a pin hole, etc. The connection between the mounting bracket 10 and the cleaning part 20 can be by bolt connection, pin connection, etc.

[0032] like Figure 3 and Figure 4 As shown, the first mounting groove 11 is open at the lower end, and this open design facilitates the connection between the first mounting groove 11 and the first support rod 301.

[0033] When connecting the first mounting groove 11 to the first support rod 301, align the open lower end of the first mounting groove 11 with the first support rod 301 and apply appropriate thrust. The first mounting groove 11 can then slide smoothly into the first support rod 301. The operation is simple and convenient.

[0034] like Figure 3 and Figure 4 As shown, the first mounting groove 11 is closed at the top. This closed design provides a supporting contact surface between the first mounting groove 11 and the first support rod 301. When the mounting bracket 10 is subjected to its own weight or other downward external forces, the first support rod 301, through the closed end of the first mounting groove 11, can provide an upward supporting force to the mounting bracket 10, making it less likely for the mounting bracket 10 to accidentally detach from the main unit 30.

[0035] like Figure 3 and Figure 4 As shown, the first mounting slot 11 is also closed on the side near the second mounting slot 12 and on the side away from the second mounting slot 12. Thus, when the mounting bracket 10 is subjected to an external force from the second mounting slot 12 towards the first mounting slot 11 or from the first mounting slot 11 towards the second mounting slot 12, the first support rod 301 can provide a supporting force to the mounting bracket 10 from the first mounting slot 11 towards the second mounting slot 12 or from the second mounting slot 12 towards the first mounting slot 11, making it less likely for the mounting bracket 10 to accidentally detach from the main unit 30.

[0036] like Figure 3 and Figure 4 As shown, the first mounting groove 11 extends obliquely from top to bottom in a direction away from the first mounting structure 131. That is, the first mounting groove 11 extends obliquely from top to bottom in a direction closer to the second mounting groove 12.

[0037] In other words, the angle between the opening directions of the first mounting slot 11 and the second mounting slot 12 is small. This layout ensures that the connection and separation paths of the two sets of mounting slots and support rods are directional, requiring only minor adjustments to the angle of the mounting bracket 10 during assembly and disassembly, making assembly and disassembly convenient.

[0038] In related technologies, the two mounting slots of the mounting bracket are set in opposite directions, which makes it difficult to adjust the angle of the mounting bracket to connect or separate from the support rod when assembling or disassembling the cleaning unit, making assembly and disassembly inconvenient.

[0039] like Figure 3 and Figure 4 As shown, the second mounting slot 12 is open on the side opposite to the first mounting slot 11. This open design facilitates the connection between the second mounting slot 12 and the second support rod 302.

[0040] When connecting the second mounting groove 12 to the second support rod 302, align the open end of the second mounting groove 12 with the second support rod 302 and apply appropriate thrust. The second mounting groove 12 can then slide smoothly into the second support rod 302. The operation is simple and convenient.

[0041] like Figure 3 and Figure 4 As shown, the second mounting groove 12 is closed at its lower end. This closed design provides a support contact surface between the second mounting groove 12 and the second support rod 302. When the mounting bracket 10 is subjected to an upward external force, the second support rod 302 can provide a downward support force to the mounting bracket 10 through the closed end of the second mounting groove 12, making it less likely for the mounting bracket 10 to accidentally detach from the main unit 30.

[0042] like Figure 3 and Figure 4 As shown, the second mounting slot 12 is also closed at the top. In this way, when the mounting bracket 10 is subjected to a downward external force, the second support rod 302 can provide an upward support force to the mounting bracket 10, making it less likely for the mounting bracket 10 to accidentally detach from the main unit 30.

[0043] like Figure 3 and Figure 4 As shown, at least a portion of the walls of the first mounting groove 11 and the second mounting groove 12 are arc-shaped.

[0044] In this way, when the cleaning unit 20 encounters an obstacle, the arc-shaped groove wall allows the first mounting groove 11 and the second mounting groove 12 to rotate or roll relative to the first support rod 301 and the second support rod 302, respectively. During this floating obstacle avoidance process, within a certain floating range of the cleaning unit 20, the first support rod 301 and the second support rod 302 always maintain contact with the groove wall of the first mounting groove 11 and the groove wall of the second mounting groove 12, respectively. The mounting bracket 10 does not separate from the first support rod 301 and the second support rod 302, reducing the knocking between the mounting bracket 10 and the first support rod 301 and the second support rod 302, thereby reducing knocking noise and reducing the impact force damage to the parts.

[0045] The arc-shaped groove walls of the first mounting groove 11 and the second mounting groove 12 can fit with the cylindrical outer contours of the first support rod 301 and the second support rod 302, forming surface contact. Compared with line contact or point contact, the surface contact formed by the arc-shaped groove walls can increase the contact area of ​​force-bearing, distribute the load, avoid local stress concentration, and make the groove walls or support rods less prone to rapid deformation or wear.

[0046] Meanwhile, the arc-shaped wall is accommodating to diameter tolerances, slight bending, or assembly deviations of the support rod. The support rod can be finely adjusted within the groove to ensure a tight fit without jamming.

[0047] When assembling the photovoltaic cleaning robot 1, the mounting bracket 10 can be connected to the main unit 30 through the cooperation of two sets of mounting slots and support rods. First, the mounting bracket 10, or the mounting bracket 10 connected to the cleaning unit 20 via the first mounting structure 131, is adjusted to be above the second support rod 302. The opening of the second mounting slot 12 faces downwards and is aligned with the second support rod 302, with the first mounting slot 11 located on the side of the second mounting slot 12 opposite to the second support rod 302. Appropriate pushing force is applied to allow the second mounting slot 12 to slide into the second support rod 302. Then, the mounting bracket 10 is rotated around the second support rod 302, causing the first mounting slot 11 to slide into the first support rod 301. This assembly process is simple and easy to operate.

[0048] like Figure 3 and Figure 4 As shown, the first mounting groove 11 is closed on the side and at the top near the second mounting groove 12, and the second mounting groove 12 is closed at the bottom. When the mounting bracket 10 is under force, the above-mentioned closed design provides two sets of mounting grooves and support rods for supporting contact surfaces. The two sets of support rods can provide the mounting bracket 10 with support forces pointing from the first mounting groove 11 to the second mounting groove 12, upward and downward, making it less likely for the mounting bracket 10 to accidentally detach from the main unit 30.

[0049] In related technologies, to mitigate the impact on the cleaning unit and prevent the mounting bracket from breaking or the cleaning unit from detaching, floating mounting brackets are used to assemble the cleaning unit onto the main unit. However, this design lacks sufficient constraint and limiting mechanisms between the cleaning unit and the main unit. When the cleaning unit is displaced upwards or downwards by obstacles, the mounting bracket can easily detach directly from the main unit, causing the cleaning unit to completely separate from the main unit, affecting actual cleaning operations. For example, some connecting brackets use an open slot connection method, but their slot structure design makes them prone to detachment.

[0050] In this embodiment, when the cleaning unit 20 encounters an obstacle, the arc-shaped groove wall allows the mounting groove and the support rod to rotate or roll relative to each other, and the support rod is always located within the space of the mounting groove. The closed surface of the side of the first mounting groove 11 near the second mounting groove 12 and the upper end can provide axial and downward limiting, suppressing the axial movement and falling of the mounting bracket 10. The lower end closed surface of the second mounting groove 12 can provide upper limiting, suppressing the upward jumping of the mounting bracket 10. The first support rod 301 and the second support rod 302 always maintain contact with the groove wall of the first mounting groove 11 and the groove wall of the second mounting groove 12, respectively, so that the mounting bracket 10 and the main unit 30 maintain connection under dynamic load, reducing the knocking between the mounting bracket 10 and the first support rod 301 and the second support rod 302, thereby reducing knocking noise, reducing the impact force damage to the parts, and reducing the risk of the cleaning unit 20 detaching.

[0051] According to the mounting bracket 1 provided in the embodiments of this application, the first mounting groove 11 and the second mounting groove 12 are designed with open ends and a small included angle in the opening direction, so that they can be aligned and smoothly slide into the corresponding support rods, which can realize the quick assembly of the cleaning part 20 and the main unit 30. By setting at least part of the groove wall of the first mounting groove 11 and the second mounting groove 12 to be arc-shaped, the support rods are allowed to rotate or roll relative to each other in the groove, so that the cleaning part 20 can float and avoid obstacles when it encounters obstacles. The first mounting groove 11 is closed on the side and top to provide axial and downward limits, and the second mounting groove 12 is closed at the bottom to provide upward limits, which together suppress the mounting bracket 10 from moving, falling or jumping, so that the cleaning part 20 is not easy to accidentally detach from the main unit 30, thereby improving the continuity and reliability of the cleaning operation of the photovoltaic cleaning robot 1.

[0052] Correspondingly, the photovoltaic cleaning robot 1 provided in the embodiments of this application can achieve rapid assembly of the cleaning unit 20 and the main unit 30 by adopting the above-mentioned mounting bracket 10. When the cleaning unit 20 encounters obstacles, it can float to avoid obstacles and is not easy to accidentally detach from the main unit 30, thereby improving the continuity and reliability of the cleaning operation of the photovoltaic cleaning robot 1.

[0053] In some embodiments, such as Figure 4 As shown, the first mounting slot 11 includes a first sub-slot 111 and a second sub-slot 112, and the first sub-slot 111 and the second sub-slot 112 are connected.

[0054] like Figure 4As shown, the wall 111a of the first sub-slot is arc-shaped. It is the mating area of ​​the first support rod 301 when the cleaning part 20 is lifted without obstruction, and it is also the main load-bearing area of ​​the first mounting groove 11. The wall 111a of the first sub-slot can be semi-circular, so that the wall 111a of the first sub-slot forms a semi-circular surface contact with the cylindrical first support rod 301. The wall 111a of the first sub-slot can avoid stress concentration caused by point contact or line contact, and can improve its compressive and bending resistance when the mounting bracket 10 bears the weight of the cleaning part 20 or the vibration of operation.

[0055] like Figure 4 As shown, the first sub-slot 111 and the second mounting slot 12 are at the same height, so that the bearing areas of the first sub-slot 111 connecting the first support rod 301 and the second mounting slot 12 connecting the second support rod 302 are on the same horizontal plane. The mounting bracket 10 can be supported at the same height, which helps the cleaning unit 20 maintain a stable posture and provides a foundation for stable cleaning operations. At the same time, the design of the first sub-slot 111 and the second mounting slot 12 being at the same height reduces the installation space occupied, which is conducive to the lightweight and compact design of the photovoltaic cleaning robot 1.

[0056] like Figure 4 As shown, the second sub-slot 112 is connected to the first sub-slot 111 and is located below the first sub-slot 111. The wall of the second sub-slot 112 extends obliquely towards the second mounting slot 12 in a direction away from the first sub-slot 111.

[0057] In this way, when the cleaning part 20 encounters an obstacle, the mating area of ​​the first mounting groove 11 and the first support rod 301 moves between the first sub-groove 11 and the second sub-groove 112, so that the first mounting groove 11 and the first support rod 301 always remain in contact during this process, and avoid the knocking noise caused by the collision between the two, and reduce the impact force on the parts.

[0058] The inclined extension of the second sub-groove 112 can provide guidance for the connection between the first support rod 301 and the first sub-groove 111, which is beneficial to the connection between the first support rod 301 and the first sub-groove 111.

[0059] In some embodiments, such as Figure 4 As shown, the center of curvature of the second sub-slot near the second mounting slot 112a and the center of curvature of the second sub-slot away from the second mounting slot 112b both coincide with the center of curvature of the arc-shaped slot wall 12a in the second mounting slot. When the second mounting slot 12 mates with the second support rod 302, the centers of curvature of the above three components also coincide with the center of curvature of the outer contour of the second support rod 302.

[0060] In this way, if the mounting bracket 10 and the cleaning part 20 connected to the mounting bracket 10 encounter an obstacle, the mounting bracket 10 and the cleaning part 20 can rotate and rise around the curvature center of the arc-shaped groove wall 12a in the second mounting groove.

[0061] During this process, the mating area between the first mounting groove 11 and the first support rod 301 moves between the first sub-groove 11 and the second sub-groove 112, so that the first support rod 301 and the groove wall 111a of the first sub-groove or the groove wall 112a of the second sub-groove close to the second mounting groove and the groove wall 112b of the second sub-groove away from the second mounting groove always remain in contact, and can avoid knocking noise caused by collision and reduce the impact force on the parts.

[0062] During this process, the second mounting groove 12 and the second support rod 302 always cooperate and always maintain surface contact, which makes it less likely to produce knocking noise caused by the collision between the two, and reduces the impact force on the parts.

[0063] During the floating obstacle avoidance process of the cleaning unit 20, the first mounting groove 11 and the second mounting groove 12 are always in contact with the first support rod 301 and the second support rod 302 respectively, and are not prone to knocking noise, reducing the impact force on the parts. The first support rod 301 and the second support rod are not prone to interfering with the upward and downward rotation of the mounting bracket 10 and the cleaning unit 20, and are not prone to detaching from the corresponding mounting groove. The mounting bracket 10 is still reliably connected to the main unit 30.

[0064] After the cleaning part 20 passes the obstacle, gravity will cause the cleaning part 20 and the mounting bracket 10 to rotate downward naturally, and the mating section of the first support rod 301 and the first mounting groove 11 will return from the second sub-groove 112 to the first sub-groove 111.

[0065] In some embodiments, such as Figure 3 As shown, the groove wall 112a of the second sub-groove near the second mounting groove and the groove wall 112b of the second sub-groove away from the second mounting groove are both longer than the radius of the first support rod 301. This makes it less likely for the first support rod 301 to detach from the opening of the second sub-groove 112, thus increasing the safety range of the cleaning unit 20 when encountering obstacles. In this embodiment, the allowable floating angle of the cleaning unit 20 can reach 30°, and the cleaning unit 20 does not separate from the main unit 30. In related technologies, the floating angle of the cleaning unit is limited to 15°.

[0066] In some embodiments, such as Figure 3 As shown, the mounting bracket 10 includes a connecting bracket 13, a first arm 14, and a second arm 15.

[0067] like Figure 3As shown, the connecting bracket 13 is located at the upper end of the mounting bracket 10 and has a first mounting structure 131. The first mounting structure 131 is located on the side of the first mounting groove 11 opposite to the second mounting groove 12.

[0068] like Figure 3 As shown, the first arm 14 is connected to the lower part of the connecting bracket 13. The first arm 14 may be provided with a perforated hole 141 to reduce the weight of the mounting bracket 10 and reduce the load on the main unit 30 driving the cleaning unit 20 to move.

[0069] like Figure 3 As shown, the second arm 15 is connected to the lower part of the connecting bracket 13. The first mounting structure 131, the first arm 14, and the second arm 15 are spaced apart along the length of the connecting bracket 13. This spaced arrangement provides space for the installation of the first mounting slot 11 and the second mounting slot 12.

[0070] like Figure 3 As shown, a first mounting groove 11 is formed between the first arm 14 and the second arm 15, and a second mounting groove 12 is formed between the second arm 15 and the connecting bracket 13. That is, the first mounting groove 11 is located below the connecting bracket 13 and between the first arm 14 and the second arm 15, and the second mounting groove 12 is located below the connecting bracket 13 and between the second arm 15 and the connecting bracket 13.

[0071] Compared to related solutions that require stacking multiple support rods in the vertical direction to achieve functions such as fixing, limiting, and lifting guidance, this design reduces the space occupied and structural complexity in the vertical direction.

[0072] In some embodiments, such as Figure 3 As shown, the second arm 15 extends downward and in a direction away from the first arm 14 from one end connected to the connecting bracket 13 to the other end. In other words, one end of the second arm 15 is fixed to the connecting bracket 13, and the overall direction of the other end is downward and then in a direction away from the first arm 14.

[0073] The second arm 15 may have a chamfered corner at its apex, on the side opposite to the connecting bracket 13 and near the first mounting groove 11. The center of the chamfer's arc may coincide with the center of curvature of the arc-shaped groove wall in the second mounting groove 12.

[0074] In this way, when the cleaning unit 20 encounters an obstacle and is lifted, the second arm 15 is less likely to interfere with the first support rod 301, and the first support rod 301 is less likely to directly hit the top corner, thus avoiding jamming or impact wear caused by hard collision.

[0075] The second arm 15 extends downward, increasing the vertical distance between the connecting bracket 13 and the free end of the second arm 15, and increasing the effective depth and space of the second mounting groove 12 in the vertical direction, so that the second mounting groove 12 can accommodate the diameter of the second support rod 302 in the vertical direction. At the same time, the downward extension of the second arm 15 can provide a constraint on the first support rod 301 from the second arm 15 to the first mounting groove 11, and can provide a constraint on the second support rod 302 from the second arm 15 to the second mounting groove 12, making it difficult for the first support rod 301 and the second support rod 302 to separate from the mounting bracket 10.

[0076] The second arm 15 extends away from the first arm 14, which can increase the space between the connecting bracket 13 and the free end of the second arm 15. The wall surface of the second arm 15 near the connecting bracket 13 can provide guidance for the installation and removal of the second support rod 302, making it convenient for the installation and removal of the second support rod 302.

[0077] like Figure 3 As shown, along the length of the connecting bracket 13, the other end of the second arm 15 protrudes outward relative to the connecting bracket 13. In other words, along the length of the connecting bracket 13, the position of the second arm 15 away from the free end of the connecting bracket 13 extends beyond the outer edge of the connecting bracket 13 in that direction.

[0078] The end of the connecting bracket 13 near the second arm 15 does not protrude from the second arm 15, which reduces the space restriction for disassembling the second support rod 302 and facilitates the installation and removal of the second support rod 302.

[0079] In some embodiments, such as Figure 3 As shown, the second arm 15 includes an arc-shaped segment 153 and an extension segment 154.

[0080] like Figure 3 and Figure 4 As shown, one end of the arc-shaped segment 153 is connected to the connecting bracket 13, forming a second mounting groove 12 with the connecting bracket 13. The side of the arc-shaped segment 153 facing away from the first arm 14 forms the groove wall of the second mounting groove 12, and its center of curvature coincides with the center of curvature of the groove wall of the second sub-groove 112 near the second mounting groove 12 and the center of curvature of the groove wall of the second sub-groove 112 facing away from the second mounting groove 12.

[0081] like Figure 3 As shown, the extension 154 is connected to the other end of the arc-shaped segment 153 and includes the free end of the second arm 15. Along the length of the connecting bracket 13, the extension 154 protrudes outward relative to the connecting bracket 13. In other words, the projection of the extension 154 along the length of the connecting bracket 13 extends beyond the boundary of the connecting bracket 13. The extension 154 can be arranged parallel or inclined relative to the connecting bracket 13.

[0082] Meanwhile, the length of the extension section 154 can be designed to be greater than the diameter of the second support rod 302, making it less likely for the second support rod 302 to detach from the mounting bracket 10 along the extension section 154, thereby increasing the safety range of the cleaning unit 20 when encountering obstacles. For example, in this embodiment, the allowable floating and lifting angle of the cleaning unit 20 can reach 30°, and the cleaning unit 20 does not separate from the main unit 30. In related technologies, the floating and lifting angle of the cleaning unit is limited to 15°.

[0083] The extension 154 can increase the space between the connecting bracket 13 and the free end of the second arm 15. The wall surface of the extension 154 near the connecting bracket 13 can provide guidance for the installation and removal of the second support rod 302, making it convenient for the installation and removal of the second support rod 302.

[0084] The end of the connecting bracket 13 near the second arm 15 does not protrude from the extension section 154, which can reduce the space restriction for disassembling the second support rod 302 and facilitate the installation and removal of the second support rod 302.

[0085] The arc segment 153 and the extension segment 154 can be processed by integral bending, welding and other methods.

[0086] In some embodiments, such as Figure 2 and Figure 3 As shown, the area of ​​the second arm 15 protruding from the connecting bracket 13 is provided with a second mounting structure 151 for mounting the limiting member 156.

[0087] like Figure 2 and Figure 3 As shown, the projection of the second mounting structure 151 along the length of the connecting bracket 13 extends beyond the boundary of the connecting bracket 13. This prevents the limiting member 156 from interfering with the second support rod 302. The second mounting structure 151 can be mounted on the extension section 154.

[0088] The function of the second mounting structure 151 is to fix the limiting member 156, which can be a threaded hole, a pin hole, etc.

[0089] The limiting member 156 can effectively prevent the second support rod 302 from separating from the second mounting groove 12, and can be a screw, pin, etc.

[0090] The limiting member 156 should be installed after the second support rod 302 mates with the second mounting groove 12. The limiting member 156 should be removed before the second support rod 302 separates from the second mounting groove 12.

[0091] In some embodiments, such as Figure 3As shown, the second arm 15 has a chamfer at the top corner of the end of the second arm 15 away from the connecting bracket 13 and the side near the first mounting groove 11. The chamfer can be the groove wall 112a of the second sub-groove near the second mounting groove, and its arc center can coincide with the curvature center of the arc-shaped groove wall in the second mounting groove 12.

[0092] In this way, when the cleaning unit 20 encounters an obstacle and is lifted, the top corner will not interfere with the first support rod 301, the first support rod 301 will not directly hit the top corner, the first support rod 301 will always maintain contact with the chamfer, and the knocking noise caused by the collision can be avoided, reducing jamming or impact wear caused by hard collision.

[0093] When the cleaning section 20 falls back after overcoming the obstacle, the chamfer can guide the first support rod 301 to slide accurately back into the first sub-slot 111 of the first mounting slot 11.

[0094] When manually loading and unloading bracket 10, chamfering can prevent operators from being scratched by sharp corners.

[0095] In some embodiments, such as Figure 3 As shown, the connecting bracket 13 is provided with a third mounting structure 132 for mounting the cable clamp.

[0096] The cable clip can be used to secure the cable between the cleaning unit 20 and the main unit 30, preventing the cable from getting caught in areas such as the first mounting slot 11 and the second mounting slot 12, or from being abraded by the sharp edges of the structure. The cable clip can be screw-fixed or push-in snap-on, etc. The cable can include motor wires, sensor wires, power supply wires, and data wires, etc.

[0097] like Figure 3 As shown, the third mounting structure 132 can be located on the connecting bracket 13 between the first mounting structure 131 and the second mounting structure 151, or on the side of the first mounting structure 131 facing away from the second mounting structure 151. The third mounting structure 132 can be in the form of a threaded hole, a snap-fit ​​groove, etc.

[0098] In the photovoltaic cleaning robot 1 of this application embodiment, as follows Figures 2-4 As shown, the first support rod 301 is located between the cleaning part 20 and the second support rod 302, and can be matched with the first mounting groove 11 located between the first mounting structure 131 and the second mounting groove 12.

[0099] like Figures 2-4 As shown, the first support rod 301 and the second support rod 302 are arranged at the same height and parallel to each other. The equal height arrangement of the first support rod 301 and the second support rod 302 can match the equal height arrangement of the first sub-slot 111 and the second mounting slot 12.

[0100] In this way, the space occupied by the first support rod 301 and the second support rod 302 used to connect the mounting bracket 10 in the height direction is small, avoiding redundant height caused by the superposition of the support rod height and the cleaning part 20 height.

[0101] Meanwhile, the cleaning unit 20 is not entirely positioned above the first support rod 301 and the second support rod 302, which helps to lower the center of gravity of the entire photovoltaic cleaning robot 1 and improve its operational stability, especially on the tilted photovoltaic panels. Furthermore, this design flattens the height profile of the photovoltaic cleaning robot 1, reducing the requirements for this critical clearance height, allowing the photovoltaic cleaning robot 1 to be easily deployed and operated in the more confined space of the photovoltaic array.

[0102] In related technologies, the design of support structures tends to include multiple support components along the height direction. However, this design increases the overall structural height, raises the center of gravity, reduces stability, and makes it difficult to deploy in scenarios with relatively low heights.

[0103] In some embodiments, such as Figure 3 and Figure 4 As shown, the sidewall of the first mounting groove 11 is longer than the diameter of the first support rod 301; and / or, the bottom wall of the second mounting groove 12 is longer than the diameter of the second support rod 302.

[0104] The side wall of the first mounting groove 11 is longer than the diameter of the first support rod 301, that is, when projected in the vertical direction, the groove wall of the first mounting groove 11 protrudes beyond the first support rod 301. In this way, after the mounting bracket 10 is connected to the main unit 30, the first mounting rod is less likely to separate from the first mounting groove 11.

[0105] The bottom wall of the second mounting groove 12 is longer than the diameter of the second support rod 302, that is, projected along the length of the mounting bracket 10. The lower wall of the second mounting groove 12 protrudes from the second support rod 302. In this way, after the mounting bracket 10 is connected to the main unit 30, the second support rod 302 is less likely to separate from the second mounting groove 12.

[0106] In some embodiments, such as Figure 1 As shown, the first support rod 301 and the second support rod 302 are located on the inner side of the main unit 30, between the two opposing side beams of the main unit 30.

[0107] In some embodiments, such as Figure 1 As shown, at least one of the first support rod 301 and the second support rod 302 is connected between the two opposing side beams of the main unit 30.

[0108] The following is combined Figures 1-4 The mounting bracket 10 of this application is described in an embodiment.

[0109] Mounting bracket 10 may include a first arm 14, a second arm 15, and a connecting bracket 13.

[0110] A first mounting groove 11 is formed between the first arm 14 and the second arm 15, and a second mounting groove 12 is formed between the second arm 15 and the connecting bracket 13.

[0111] The first mounting groove 11 is open at its lower end and closed on the side near the second mounting groove 12 and at its upper end. The second mounting groove 12 is open away from the first mounting groove 11 and closed at its lower end. The first mounting groove 11 extends obliquely from top to bottom in a direction away from the first mounting structure 131. At least a portion of the groove walls of the first mounting groove 11 and the second mounting groove 12 are arc-shaped.

[0112] The first mounting groove 11 includes a first sub-groove 111 and a second sub-groove 112. The first sub-groove 111 is at the same height as the second mounting groove 12. The center of curvature of the second sub-groove near the groove wall 112a of the second mounting groove and the center of curvature of the second sub-groove away from the second mounting groove 112b both coincide with the center of curvature of the arc-shaped groove wall 12a in the second mounting groove.

[0113] The second arm 15 extends downward from one end connected to the connecting bracket 13 and in a direction away from the first arm 14, and may include an arcuate segment 153 and an extension segment 154. Along the length direction of the connecting bracket 13, the extension segment 154 protrudes outward relative to the connecting bracket 13, and the protruding area is provided with a second mounting structure 151 for mounting the limiting member 156.

[0114] The connecting bracket 13 has a first mounting structure 131 for mounting the cleaning unit 20 to the main unit 30.

[0115] In this way, the angle between the opening directions of the first mounting slot 11 and the second mounting slot 12 is small. When loading and unloading, only a small adjustment of the angle of the mounting bracket 10 is needed to complete the connection or separation of the two sets of mounting slots and support rods. The assembly and disassembly are simple and convenient, and easy to operate.

[0116] When the mounting bracket 10 is subjected to force, the closed design of the first mounting groove 11 and the second mounting groove 12 provides two sets of mounting grooves and support rods for supporting contact surfaces. The two sets of support rods can provide the mounting bracket 10 with support forces pointing from the first mounting groove 11 to the second mounting groove 12, upward and downward, so that the mounting bracket 10 is not easy to accidentally detach from the host 30.

[0117] When the cleaning unit 20 encounters an obstacle, the arc-shaped groove wall allows the first mounting groove 11 and the second mounting groove 12 to rotate or roll relative to the first support rod 301 and the second support rod 302, respectively. Within a certain floating range of the cleaning unit 20's obstacle avoidance, the first support rod 301 and the second support rod 302 always maintain contact with the groove wall of the first mounting groove 11 and the groove wall of the second mounting groove 12, respectively. The mounting bracket 10 does not separate from the first support rod 301 and the second support rod 302, reducing the knocking between the mounting bracket 10 and the first support rod 301 and the second support rod 302, thereby reducing knocking noise and reducing impact damage to the parts.
