[0039] Combine the following Figures 1 to 10 The utility model describes a garbage bin and a photovoltaic cleaning robot.

[0040] See also Figures 1 to 3 as well as Figure 7 As shown, the trash bin 100 provided by the embodiment of the utility model includes a housing 110 , a trash storage device 120 , an air duct 130 , a telescopic driving mechanism 140 and a rotating driving mechanism 150 . The shell 110 includes a first groove 111 arranged on the side; the garbage storage device 120 is slidably arranged in the first groove 111, and the garbage storage device 120 is provided with a discharge port 121; the air duct 130 is arranged in the shell 110, and the air duct 130 connects the garbage storage device 120 with the outside of the garbage bin 100, and the garbage can enter the garbage bin through the air duct 130; the telescopic driving mechanism 140 is arranged on the shell 110, and the garbage storage device 120 is connected to the telescopic driving mechanism 140 to drive the garbage storage device 120 to switch between an initial position connected to the air duct 130 and a dumping position extending out of the first groove 111; the rotating driving mechanism 150 is arranged on the telescopic driving mechanism 140, and the garbage storage device 120 is connected to the rotating driving mechanism 150 to drive the garbage storage device 120 to switch between an initial angle of the discharge port 121 above the horizontal plane and a dumping angle of the discharge port 121 below the horizontal plane.

[0041] Specifically, see Figure 1 and Fig.10 As shown, the trash bin 100 can be installed on the body 200 of the photovoltaic cleaning robot. When the photovoltaic cleaning robot is cleaning the photovoltaic panel, the trash bin 100 is in the initial position and initial angle. The cleaning mechanism (such as a roller brush) of the photovoltaic cleaning robot separates the garbage (mainly dust) attached to the surface of the photovoltaic panel from the photovoltaic panel. At the same time, a negative pressure can be formed in the air duct 130 under the action of the fan, and the garbage is sucked into the air duct 130 and finally enters the garbage storage device 120.

[0042] When the garbage in the garbage storage device 120 is accumulated to a certain extent, the photovoltaic cleaning robot is driven to reach a designated position (e.g., the edge of the photovoltaic panel) to prepare for dumping the garbage. First, under the driving action of the telescopic driving mechanism 140, the garbage storage device 120 is pushed out from the first groove 111 set on the side of the housing 110 to the dumping position.

[0043] Then, the garbage storage device 120 is driven to rotate by the rotary drive mechanism 150, and the garbage storage device 120 is rotated from the initial angle of the discharge port 121 above the horizontal plane to the dumping angle of the discharge port 121 below the horizontal plane, and the garbage is discharged to the outside through the discharge port 121.

[0044] After the garbage is discharged, the garbage storage device 120 is driven to rotate by the rotating drive mechanism 150, and the discharge port 121 is rotated from the dumping angle below the horizontal plane to the initial angle of the discharge port 121 above the horizontal plane, and then under the driving action of the telescopic drive mechanism 140, the garbage storage device 120 is reset from the dumping position to the initial position connected to the air duct 130, and the photovoltaic cleaning robot can continue to perform cleaning operations on the photovoltaic panels.

[0045] The trash bin 100 provided by the utility model solves the defect that the existing photovoltaic cleaning robot needs to manually dump the trash stored in the robot after cleaning for a certain period of time, which greatly reduces the cleaning efficiency. At the same time, it avoids the risk that the photovoltaic cleaning robot is too heavy due to excessive trash, which shortens the battery life of the photovoltaic cleaning robot and damages the photovoltaic panel.

[0046] It should be noted that the above “initial angle of the garbage storage device 120 when the discharge port 121 is above the horizontal plane” specifically means: at the initial angle, the discharge port 121 of the garbage storage device 120 is vertically upward or tilted upward at a set angle to prevent garbage from leaking from the discharge port 121. The above “dumping angle of the discharge port 121 below the horizontal plane” specifically means: at the dumping angle, the discharge port 121 of the garbage storage device 120 is vertically downward or tilted downward at a set angle to dump the garbage stored in the garbage storage device 120 to the outside through the discharge port 121.

[0047] See also Figure 2 and Figure 3 As shown, as a preference, in this embodiment, when the garbage storage device 120 is at the initial angle, the discharge port 121 is arranged vertically upward, which is conducive to the accumulation of garbage in the garbage storage device 120 and prevents garbage leakage; when the garbage storage device 120 is at the dumping angle, the discharge port 121 is arranged tilted downward, which can reduce the rotation stroke of the garbage storage device 120 while ensuring that the garbage can be smoothly discharged to the outside through the discharge port 121.

[0048] The telescopic drive mechanism 140 can be a hydraulic drive mechanism, a mechanical drive mechanism or a pneumatic drive mechanism. Among them, the hydraulic drive mechanism provides power and controls the telescopic movement of the mechanism through a hydraulic system, and is realized through components such as hydraulic cylinders, hydraulic pumps and control valves. It can provide a large telescopic driving force and precise control for the garbage storage device 120, and is suitable for photovoltaic cleaning robots with larger volumes and specifications. The mechanical drive mechanism can drive the telescopic movement of the garbage storage device 120 through mechanical structures such as gear racks 1461 and ball screws and cooperate with a drive motor. The pneumatic drive mechanism uses pneumatic elements (such as cylinders) to convert gas power into mechanical movement to achieve the drive of telescopic movement, thereby driving the garbage storage device 120 to move between the initial position and the dumping position.

[0049] The rotary drive mechanism 150 can be directly driven by a drive motor, for example, the garbage storage device 120 is directly connected to the output shaft of the drive motor, and the output shaft of the drive motor rotates to drive the garbage storage device 120 to rotate. It can also be indirectly driven by a motor, for example, a transmission mechanism (such as a gear mechanism, etc.) is set between the output shaft of the drive motor and the garbage storage device 120, and the power of the drive motor is transmitted to the garbage storage device 120 by the transmission mechanism, so as to drive the garbage storage device 120 to rotate.

[0050] See also Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the telescopic drive mechanism 140 includes a first telescopic arm 141 and a second telescopic arm 142, wherein the first telescopic arm 141 is disposed on the side wall of the first groove 111, and the first telescopic end of the first telescopic arm 141 is connected to the garbage storage device 120; the second telescopic arm 142 is disposed on the side wall opposite to the first telescopic arm 141 in the first groove 111, and the second telescopic end of the second telescopic arm 142 is connected to the garbage storage device 120. By utilizing the first telescopic arm 141 and the second telescopic arm 142 disposed on the opposite side walls of the first groove 111 to telescopically drive the garbage storage device 120, the stability of the garbage storage device 120 when moving between the initial position and the dumping position can be improved.

[0051] According to some embodiments of the present invention, the rotation drive mechanism 150 is disposed at least at one of the first telescopic end and the second telescopic end.

[0052] For example, in some embodiments, the rotary drive mechanism 150 is disposed at the first telescopic end, the garbage storage device 120 is located at the side where the first telescopic end is located and is connected to the rotary drive mechanism 150 as the driving side, and the garbage storage device 120 is located at the side where the second telescopic end is located and is rotatably connected to the second telescopic end as the driven side, which can reduce the number of rotary drive mechanisms 150, simplify the mechanism, and save costs.

[0053] See also Figure 4 As shown, in this embodiment, preferably, a rotation drive mechanism 150 is provided on both the first telescopic end and the second telescopic end, and the two rotation drive mechanisms 150 are symmetrically arranged on both sides of the garbage storage device 120 to synchronously drive the garbage storage device 120 to rotate, which can improve the driving force. When a lot of garbage is stored in the garbage storage device 120, the two rotation drive mechanisms 150 can operate synchronously to ensure the smooth rotation of the garbage storage device 120. At the same time, by symmetrically arranging the rotation drive mechanisms 150 on both sides of the garbage storage device 120, a balance and symmetry effect can be achieved, and the stability and reliability of the entire garbage storage device 120 during rotation can be improved.

[0054] See also Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the first telescopic arm 141 includes a first drive motor 143, a drive gear 144 and a telescopic member 145, the first drive motor 143 is arranged on the housing 110; the drive gear 144 is arranged on the first output shaft of the first drive motor 143; the telescopic member 145 is slidably arranged on the side wall of the first groove 111, and the telescopic member 145 is provided with a rack 1461, which is meshed with the drive gear 144, and has a simple structure and a fast driving response speed. It should be noted that the second telescopic arm 142 can have the same structure as the first telescopic arm 141 to ensure the stable telescopic of the garbage storage device 120.

[0055] Specifically, see Figure 6 As shown, in this embodiment, a first transmission connecting member 146 is provided at the end of the telescopic member 145 , and a rack is provided at the bottom of the first transmission connecting member 146 and meshes with the driving gear 144 .

[0056] During the movement of the garbage storage device 120 from the initial position to the dumping position, the first output shaft of the first drive motor 143 rotates, driving the drive gear 144 to rotate. Since the rack 1461 provided on the telescopic member 145 is engaged with the drive gear 144, the rotational motion of the first drive motor 143 is converted into the linear motion of the telescopic member 145, and then the garbage storage device 120 is driven to move linearly through the telescopic member 145.

[0057] See also Figure 6As shown, according to some embodiments of the utility model, the telescopic member 145 includes a first telescopic section 1451 and a second telescopic section 1452, the first telescopic section 1451 is slidably disposed on the side wall of the first groove 111; the second telescopic section 1452 is slidably disposed on the first telescopic section 1451, and the rack 1461 is disposed on the second telescopic section 1452; and the first telescopic section 1451 can slide under the drive of the second telescopic section 1452. After the second telescopic section 1452 slides on the first telescopic section 1451 for a preset distance, the second telescopic section 1452 can abut against the first telescopic section 1451, thereby driving the first telescopic section 1451 to slide on the side wall of the first groove 111. By setting the telescopic member 145 as the first telescopic section 1451 and the second telescopic section 1452, within the same travel range, when the first telescopic section 1451 and the second telescopic section 1452 are retracted, the occupied length of the telescopic member 145 can be effectively reduced.

[0058] Specifically, during the process of the garbage storage device 120 moving from the initial position to the dumping position, the first output shaft of the first drive motor 143 rotates to drive the drive gear 144 to rotate, and under the meshing action of the gear rack 1461, the second telescopic section 1452 is driven to move linearly relative to the first telescopic section 1451 and drive the garbage storage device 120 to move. After a certain stroke, the first telescopic section 1451 continues to move outward relative to the side wall of the first groove 111, and finally the garbage storage device 120 reaches the dumping position.

[0059] It should be noted that, in some embodiments, a slide groove can be set on the side wall of the first groove 111, and the first telescopic section 1451 of the telescopic member 145 can be slidably set in the slide groove, so that the first telescopic section 1451 of the telescopic member 145 and the side wall of the first groove 111 are configured in a sliding connection relationship.

[0060] As a preference, see Figure 4 and Figure 5 As shown, in this embodiment, a sliding fixing member 147 with a sliding groove is provided on the side wall of the first groove 111, and the first telescopic section 1451 of the telescopic member 145 slides in cooperation with the sliding groove of the sliding fixing member 147, and the first telescopic section 1451 of the telescopic member 145 and the side wall of the first groove 111 can also be configured into a sliding connection relationship.

[0061] In one or more embodiments, the second telescopic arm 142 may include a third telescopic section and a fourth telescopic section, the third telescopic section may be slidably disposed on the side wall of the first groove 111, and the fourth telescopic section may be slidably disposed on the third telescopic section. In some embodiments, the second telescopic arm 142 may also include a fourth drive motor (not shown), the fourth drive motor is disposed on the housing 110, a rack may also be disposed on the fourth telescopic section, the fourth drive motor is connected to the rack via a drive gear (not shown), the fourth drive motor rotates to drive the fourth telescopic section to slide in the first groove, and the third telescopic section may slide under the drive of the fourth telescopic section.

[0062] See also Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the trash bin 100 further includes a first flange 122, which is located on a side of the trash storage device 120 away from the housing 110, and the first flange 122 at least partially overlaps with the first telescopic section 1451 in the horizontal projection direction. By arranging the first flange 122 on the side of the trash storage device 120 away from the housing 110, and making the first flange 122 at least partially overlap with the first telescopic section 1451 in the horizontal projection direction, during the process of the trash storage device 120 moving from the dumping position to the initial position, if the first telescopic section 1451 cannot be driven by the second telescopic section 1452 to return to the initial position, the first flange 122 can be used to drive the first telescopic section 1451 to return to the initial position. In some embodiments, the trash bin 100 may further include a third flange, which is located on a side of the trash storage device 120 away from the housing 110, and the third flange at least partially overlaps with the third telescopic section in the horizontal projection direction.

[0063] See also Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the first flange 122 includes a first magnet 160, and the position on the housing 110 corresponding to the first magnet 160 includes a second magnet 170. When the garbage storage device 120 is in the initial position, the first magnet 160 and the second magnet 170 attract each other. When the garbage storage device 120 is in the initial position, the first magnet 160 and the second magnet 170 can fix the garbage storage device 120 and the housing 110 under the adsorption and fixing effect generated by the first magnet 160 and the second magnet 170, so as to prevent the garbage storage device 120 from being separated from the initial position under the vibration of the cleaning mechanism (such as a roller brush, a motor, etc.) of the photovoltaic cleaning robot.

[0064] See also Figure 4 and Figure 5As shown, according to some embodiments of the present invention, the rotary drive mechanism 150 includes two second drive motors 151, one of which is disposed on the first telescopic end, and the other second drive motor 151 is disposed on the second telescopic end, and the second output shaft of the second drive motor 151 is connected to the garbage storage device 120. By arranging the second drive motors 151 on both the first telescopic end and the second telescopic end, and driving the garbage storage device 120 to rotate simultaneously by the two second drive motors 151, a stronger driving force can be provided to ensure that the garbage storage device 120 has sufficient power when rotating. At the same time, the symmetrical arrangement of the two second drive motors 151 can ensure the balance and stability of the rotary drive mechanism 150. By symmetrical driving, the deflection or instability of the garbage storage device 120 caused by uneven driving force can be avoided, thereby increasing the reliability of the garbage bin 100 during operation.

[0065] According to some embodiments of the present invention, the rotary drive mechanism 150 may further include a second drive motor 151, which is disposed on the first telescopic end or the second telescopic end, and the second output shaft of the second drive motor 151 is connected to the garbage storage device 120. For example, the second drive motor 151 is disposed at the first telescopic end, and the corresponding side of the garbage storage device 120 is connected to the second output shaft of the second drive motor 151. As the driving side, the second telescopic end is rotationally connected to the corresponding side of the garbage storage device 120. As the driven side, the second drive motor 151 located on the driving side can directly drive the rotational movement of the garbage storage device 120, thereby simplifying the structure of the rotary drive mechanism 150 and reducing the number of components.

[0066] Specifically, see Figure 4 and Figure 5 As shown, a second output shaft of the second drive motor 151 is provided with a second transmission connection member 152 , and the second transmission connection member 152 is connected to the garbage storage device 120 , that is, the power of the second drive motor 151 is transmitted to the garbage storage device 120 through the second transmission connection member 152 .
