Wherein the mounting member 110 is used to mount the locking member 120 and the driving assembly 130, the mounting member 110 may be a mounting plate, a mounting bracket, a mounting seat, etc. Of course, the mounting member 110 may be a mounting structure independent from the photovoltaic cleaning robot 10, or may be a part of the photovoltaic cleaning robot 10 itself (for example, may be a cabinet of the photovoltaic cleaning robot 10). Referring to fig. 2, in an embodiment of the present invention, the mounting member 110 is disposed by taking a mounting plate as an example, and the driving assembly 130 is fixedly mounted on the mounting plate by screws.

The locking member 120 is rotatably connected to the mounting member 110 through the rotating shaft 140, the rotating axis is a central axis of the rotating shaft 140, as shown in fig. 6, the locking member has a first mounting hole 1231, the mounting member has a second mounting hole (not shown), the rotating shaft 140 is inserted into the first mounting hole 1231 and the second mounting hole, and the locking member 120 is driven by the driving assembly 130 to rotate around the rotating shaft 140 so as to drive the locking portion 124 to rotate synchronously. The first mounting hole 1231 may be located at the middle of the locking member 120, or at one end of the locking member 120. It is understood that the locking member 120 can be rotatably mounted to the mounting member 110 in a vertical plane, or rotatably mounted to the mounting member 110 in a horizontal plane, and the rotation plane of the locking member 120 is not limited thereto.

When the driving assembly 130 is disposed above or below the locking member 120, the driving assembly 130 may be a linear moving mechanism that indirectly drives the locking member 120 to rotate around the rotation axis by applying a pushing force and a pulling force; when the driving assembly 130 is disposed at both sides of the locker 120, the driving assembly 130 may be a motor directly driving the locker 120 to rotate about the rotation axis by an output torque.

When the driving assembly 130 is disposed above the locking member 120, the driving assembly 130 and the locking member 120 may be connected by a pin or a screw, or may abut against each other. It can be appreciated that the driving assembly 130 and the locking member 120 are connected by a pin or a screw, so that the driving assembly 130 and the locking member 120 are connected more stably, and the locking member 120 can quickly perform corresponding actions under the driving of the driving assembly 130; and adopt the butt can be easy to assemble, need not to consider positioning accuracy, and conveniently dismantle drive assembly 130 in the later maintenance process, can improve maintenance efficiency.

It can be understood that the rotation angle of the locking part 124 is determined by the stroke of the driving assembly 130 moving up and down, and in this embodiment, in order to prevent the locking part 124 from interfering with the photovoltaic panel, when the locking part 124 is dropped to the lowest position, the locking member 120 is entirely in a flat state under the limit of the driving assembly 130.

Referring to fig. 3 and 4, the entire locking and unlocking process of the photovoltaic cleaning robot 10 is as follows:

when the photovoltaic cleaning robot 10 moves to the stop position after the cleaning operation is finished, or the photovoltaic cleaning robot 10 senses that the weather suddenly changes and needs to return to the stop position through a sensor (for example, the wind speed sensor detects that the wind speed suddenly increases), the photovoltaic cleaning robot 10 sends a control signal to control the driving assembly 130 to move downward, and drive the locking member 120 to rotate clockwise around the rotation axis thereof, so as to drive the locking portion 124 to lift and keep at the lifted position, as shown in fig. 4, at this time, the locking portion 124 is in the unlocked state, so that the locking portion 124 can pass over the preset clamping portion 20 at the stop position, so that the photovoltaic cleaning robot 10 returns to the stop position; of course, it should be noted that the locking member 120 may be always in the unlocked state during the operation of the photovoltaic cleaning robot 10 (leaving the shutdown position);

when the photovoltaic cleaning robot 10 reaches the stop position, a sensor preset on the photovoltaic cleaning robot 10 senses (or senses in other ways) a sensor preset on the stop position, at this time, the photovoltaic cleaning robot 10 stops and sends a locking signal to the driving assembly 130 to control the driving assembly 130 to move upwards, and the locking member 120 is driven to rotate anticlockwise around the rotation axis thereof, so as to drive the locking portion 124 to fall down, as shown in fig. 3, at this time, the locking portion 124 is in a locking state, and the locking portion 124 is in locking fit with the clamping portion 20, so that the photovoltaic cleaning robot 10 is locked at the stop position;

when the photovoltaic cleaning robot 10 receives the cleaning instruction again to prepare to leave the shutdown position, the photovoltaic cleaning robot 10 sends an unlocking signal to the driving assembly 130, and controls the driving assembly 130 to move downward, and the locking member 120 is driven to rotate clockwise around the rotation axis thereof, so as to drive the locking portion 124 to lift up and disengage from the locking engagement with the engaging portion 20, as shown in fig. 4, the locking portion 124 is switched to the unlocking state again, so as to release the locking of the photovoltaic cleaning robot 10, and the photovoltaic cleaning robot 10 can smoothly leave the shutdown position (it should be noted that, the clockwise and counterclockwise directions in the above process are referred to fig. 3 and fig. 4).

According to the technical scheme, in the locking mechanism 100 of the photovoltaic cleaning robot, the locking member 120 is rotatably connected with the mounting member 110, the driving assembly 130 is mounted on the mounting member 110 and is in driving connection with the locking member 120, and the driving assembly 130 drives the locking member 120 to rotate around the rotation axis of the locking member, so that the locking part 124 is driven to rotate and switch between an unlocking state and a locking state; so, when photovoltaic cleans machine people 10 and is in the stall position, drive assembly drive locking piece 120 rotates around its axis of rotation and makes locking portion 124 and block portion 20 locking cooperation to clean machine people 10 with the photovoltaic and lock in the stall position, can prevent that photovoltaic from cleaning machine people 10 from being blown off the stall position by the strong wind, prevent that photovoltaic from cleaning machine people 10 from blowing off from the photovoltaic grillage.

Further, in order to stably lock the locking portion 124 to the engaging portion 20, in an embodiment, the locking portion 124 is preferably a hook, and the hook is configured to be engaged with the engaging portion 20.

Further, in an embodiment, referring to fig. 2 and 6, the hook has an engaging surface 1241 engaging with the engaging portion 20.

The hook is disposed on the lower side of the locking member 120 and extends along the lower side, the shape of the hook may be various, and the hook may be a column (for example, a rectangular column or a cylinder), or a plate, and the specific shape of the hook is not limited herein. In this embodiment, in order to facilitate the processing and assembling of the locking member 120, the locking member 120 is plate-shaped (has a certain thickness) to enhance the overall strength of the locking member 120, and meanwhile, the installation is also convenient, so that the hook is also correspondingly arranged to be plate-shaped.

It is understood that the push rod 132 is mounted at the output end of the driving member 132, and the driving member 131 may be an air cylinder or an electric cylinder.

It should be noted that the middle portion of retaining member 120 is pivotally connected to mounting member 110, and the middle portion of retaining member 120 is an area near the middle of retaining member 120 to distinguish the ends of retaining member 120, and is not limited to the middle of retaining member 120, and may be located at a position that is offset to the left or right of the middle of retaining member 120.
