Since the first charging contact 120 for charging is generally disposed on the first body 110, in order to facilitate the charging of the first charging contact 120, the conventional first charging contact 120 is generally exposed to the air, and is thus easily polluted by dust or corroded by rainwater, which in turn results in a great reduction in charging efficiency. In the present utility model, a first protection cover 130 may be disposed, where the first protection cover 130 is movably connected to the first body 110, so as to be capable of opening or closing the first charging contact 120. Specifically, when it is not necessary to charge the first charging contact 120, the first charging contact 120 may be enclosed within the first protection cover 130 to avoid dust or rainwater from affecting the first charging contact 120. When it is desired to charge the cleaning robot 100 through the first charging contact 120, the first protection cover 130 is opened to expose the first charging contact 120.
The cleaning assembly also has a charging base station 200, which charging base station 200 is typically provided on a photovoltaic rack, in particular at the end close to the photovoltaic assembly, i.e. at the stand.

Likewise, second protective cover 220 may be hingedly disposed with charging base station 200, as well as slidably disposed. For example, the second protection cover 220 is hinged to the charging base station 200, and when the second protection cover 220 rotates relative to the charging base station 200, the second protection cover 220 has at least two states, in the first state, the second protection cover 220 is opened to expose the second charging contact 210, and in the second state, the second protection cover 220 encloses a closed space, so that the second charging contact 210 is enclosed in the space. When the second protection cover 220 is slidably connected to the charging base station 200, the second protection cover 220 also has at least two states when sliding relative to the charging base station 200, in the first state, the second protection cover 220 is opened to expose the second charging contact 210, and in the second state, the second protection cover 220 encloses a closed space, so that the second charging contact 210 is enclosed in the space. Or the second protective cover 220 has a movable door that opens to reveal the second charging contact 210 and closes to enclose the second charging contact 210.

By movably connecting the second protection cover 220 to the charging base station 200, and the second protection cover 220 can open or close the second charging contact 210, when the second protection cover 220 is in a state of closing the second charging contact 210, the second charging contact 210 can be prevented from being influenced by dust or rainwater to fail. When the user needs to contact the first charging contact 120 with the second charging contact 210 to charge the cleaning robot 100, the second protection cover 220 may be opened to achieve the effect of charging the cleaning robot 100. By providing the first protective cover 130 and/or the second protective cover 220, at least one of the first charging contact 120 and the second charging contact 210 can be protected, so that charging stability and charging efficiency can be improved.

Through including first half cover 131 and second half cover 132 with first protection cover 130, first half cover 131 and second half cover 132 all swing joint in first body 110, then when first half cover 131 and second half cover 132 keep away from each other, can make first charging contact 120 reveal to be convenient for first charging contact 120 and second charging contact 210 contact, in order to realize the effect of charging to cleaning robot 100. When the first half cover 131 and the second half cover 132 are close to each other and enclose together, the first charging contact 120 can be sealed in a space formed by enclosing the first half cover 131 and the second half cover 132, so that the first half cover 131 and the second half cover 132 together have a better protection effect on the first charging contact 120 when the first charging contact 120 is not contacted with the second charging contact 210. In addition, by arranging the two half covers, on one hand, the motion trail of each half cover is smaller, so that excessive space occupation is avoided; on the other hand, the efficiency of opening or closing the first charging contact 120 can be improved. Specifically, the first half-shell 131 is hinged to the first body 110, and is also slidably connected thereto. The second half 132 may be hinged to the first body 110 or may be slidably connected thereto.
Further, in the present embodiment, the first half cover 131 and the second half cover 132 are both slidably connected to the first body 110.

Specifically, the first half cover 131 and the second half cover 132 are provided with sliding rails, the body is correspondingly provided with sliding grooves, and the sliding rails are slidably arranged in the sliding grooves.
In order to facilitate automation, referring to fig. 1 to 3, the cleaning assembly further includes a driving assembly 140, wherein the first half-cover 131 and the second half-cover 132 are in transmission connection with the driving assembly 140, and the driving assembly 140 drives the first half-cover 131 and the second half-cover 132 away from each other to expose the first charging contact 120, or the driving assembly 140 drives the second half-cover 132 close to each other to close the first charging contact 120.
The driving component 140 is in transmission connection with the first half cover 131 and the second half cover 132, so as to drive the first half cover 131 and the second half cover 132 to be far away from or close to each other, and further, the first charging contact 120 can be exposed, so that the cleaning robot 100 can be charged conveniently, or the first charging contact 120 can be sealed, so that the first charging contact 120 can be protected conveniently.
Specifically, as an example, referring to fig. 1 to 3 in combination, the driving assembly 140 includes a motor, a gear 141 and a rack 142, wherein the gear 141 is installed at an output end of the motor; the two racks 142 are provided, the two racks 142 are symmetrically disposed about the center of the gear 141, and the two racks 142 are respectively connected to the first half cover 131 and the second half cover 132.
So set up, then the motor rotates and drives gear 141 rotation, and gear 141 rotates and drives two racks 142 respectively towards opposite direction motion. For example, when the motor rotates clockwise, the two racks 142 respectively drive the first half cover 131 and the second half cover 132 to move in the directions away from each other, so as to achieve the effect of exposing the first charging contact 120; when the motor rotates counterclockwise, the two racks 142 respectively drive the first half-cover 131 and the second half-cover 132 to move toward each other, so as to achieve the effect of closing the first charging contact 120.
Of course, in other embodiments, the driving assembly 140 may also have other structures, for example, the driving assembly 140 may include a motor, a screw, and two nuts, the screw extends along the opening and closing direction of the first half cover 131 and the second half cover 132, the screw has a first spiral portion and a second spiral portion with opposite rotation directions along the extending direction, the two nuts are respectively engaged with the first spiral portion and the second spiral portion, and the two nuts are respectively fixedly connected with the first half cover 131 and the second half cover 132. So set up, then when the motor rotates in order to drive the screw rod and rotate, first screw portion and second screw portion on the screw rod respectively drive two nuts and move towards opposite direction, and then make two half covers of being connected with two nuts fixed also move towards opposite direction to realize the action of opening and shutting of first half cover 131 and second half cover 132.
Further, a sealing ring (not shown) is mounted on a side of the first half cover 131 facing the second half cover 132 and/or a side of the second half cover 132 facing the first half cover 131.
Specifically, a sealing ring is mounted to a side of the first half cover 131 facing the second half cover 132. Alternatively, a sealing ring is mounted to the side of the second half cover 132 facing the first half cover 131. Alternatively, the sealing rings are mounted on the side of the first half cover 131 facing the second half cover 132 and the side of the second half cover 132 facing the first half cover 131. By the arrangement, when the first half cover 131 and the second half cover 132 are close to each other for covering, a better sealing effect can be achieved through the sealing ring, and the protection effect on the first charging contact 120 is further improved. The sealing ring may be connected to the first half cover 131 and/or the second half cover 132 by bonding or clamping.
Further, the first body 110 is further provided with a sensor (not shown), and the sensor is electrically connected to the driving assembly 140 for detecting the position of the cleaning robot 100.
Through setting up the sensor, then when the sensor detects that cleaning robot 100 moves to the position of corresponding stand, can give drive assembly 140 with this signal transfer, and then drive first half cover 131 and second half cover 132 keep away from each other in order to reveal first charging contact 120 through drive assembly 140, and then the second charging contact 210 that is convenient for first charging contact 120 and charging base station 200 contacts to realize the effect of charging to cleaning robot 100. Specifically, the sensor may be a photoelectric sensor, a hall sensor, or the like, as long as an effect of detecting whether the cleaning robot 100 moves to the stand can be achieved.
Based on the scheme that the second protection cover 220 is movably disposed on the charging base station 200, in this embodiment, referring to fig. 4 and 5 in combination, the second protection cover 220 includes a box 221 and a hinged door 222, the box 221 is fixedly disposed on the charging base station 200, the box 221 has an opening 221a facing the first charging contact 120, and the second charging contact 210 is disposed on a side wall of the box 221 opposite to the opening 221 a; the hinge door 222 is installed at the opening 221a and is hinged with the case 221; the hinge door 222 closes the opening 221a to close the second charging contact 210, and the hinge door 222 opens to expose the second charging contact 210.
In the present embodiment, "the case 221 has the opening 221a facing the first charging contact 120" is based on the state when the cleaning robot 100 moves to the stand. When the cleaning robot 100 moves to the stand, the cleaning robot 100 moves toward the direction of the second charging contact 210 close to the charging base station 200, and at this time, the first charging contact 120 pushes the hinged door 222 open, so as to actively expose the second charging contact 210, and then contacts the second charging contact 210, so that the charging base station 200 charges the cleaning robot 100. Therefore, by such arrangement, the effect of opening the hinge door 222 can be achieved while the first charging contact 120 and the second charging contact 210 are close to each other, thereby avoiding the situation that the hinge door 222 is opened manually and the hinge door 222 is opened separately taking time, and improving the efficiency of the first charging contact 120 and the second charging contact 210 contacting each other. Since the hinge door 222 is hinged to the case 221, the hinge door 222 is movable with respect to the charging base station 200.
In one embodiment, as shown in fig. 4 or 5, the hinge door 222 has a top end hinged with the case 221.
By hinging the top end of the hinge door 222 with the case 221, the hinge door 222 is caused to automatically open the opening 221a of the case 221 under the pushing of the first charging contact 120, and at this time, the bottom end of the hinge door 222 is lifted upward. And when the first charging contact 120 withdraws from the box 221, the bottom end of the hinged door 222 falls under the action of gravity, so that the opening 221a can be automatically closed, the effect that the hinged door 222 can be opened or closed without separately arranging the driving component 140 is achieved, and the structure of the second protective cover 220 in the embodiment is simpler, and the cost is saved. It should be noted that, in the technical scheme of the utility model, the top end and the bottom end are all based on the state that the charging base station is normally installed on the photovoltaic bracket, and the side of the charging base station, which is close to the ground, is the bottom end, and the side, which is far away from the ground, is the top end.
Further, the cleaning assembly further includes an elastic member (not shown), one end of which is connected to the case 221 and the other end of which is connected to the hinge door 222, so that the elastic member can be deformed when the hinge door 222 opens the opening 221 a.
Since the hinge door 222 forces the elastic member to deform when the opening 221a is opened, after the acting force to the hinge door 222 is removed, the hinge door 222 is rebounded to a state of closing the opening 221a of the case 221 under the action of the elastic member, thereby achieving the effect of automatically closing the second charging contact 210. Specifically, the elastic member may be a cylindrical spring having one end connected to the outer wall surface of the case 221 and the other end crossing the hinge shaft of the hinge door 222 and connected to the hinge door 222 such that the spring is stretched when the hinge door 222 opens the opening 221a of the case 221 by the driving force of the first charging contact 120; when the driving force to the hinge door 222 is removed, the spring is deformed and drives the hinge door 222 to return to the original position, i.e., the state of closing the opening 221 a. Or the elastic member may be a torsion spring, where the torsion spring is sleeved outside the hinge shaft of the hinge door 222, and one end of the torsion spring is connected with the hinge door 222, and the other end of the torsion spring is connected with the box 221, so that when the hinge door 222 opens the opening 221a of the box 221 under the driving force of the first charging contact 120, the torsion spring rotates around the hinge shaft, and then drives the torsion spring to deform; when the driving force to the hinge door 222 is removed, the torsion spring is deformed and drives the hinge door 222 to return to the original position, i.e., the state of closing the opening 221 a.
Further, the space formed in the case 221 is adapted to the first charging contact 120, so that the first charging contact 120 fills the case 221 when the first charging contact 120 is in contact with the second charging contact 210.
So set up, then when first charging contact 120 and second charging contact 210 contact each other, promptly charging base station 200 charges in-process to cleaning robot 100, box 221 can have better protection effect to first charging contact 120 equally, and then guarantees also has better leakproofness in the charging process.
Specifically, the hinge door 222 may be provided with one, and the hinge door 222 can cover the entire opening 221 a; or two hinged doors 222 are provided, the two hinged doors 222 being mirror-symmetrically arranged. By providing a hinged door 222, the number of parts is reduced, facilitating installation and removal. By providing two hinged doors 222, the range of rotation of each hinged door 222 is reduced, thereby facilitating the second protective cover 220 to be smaller and thus occupy less space.
Further, a sealing strip (not shown) is provided on a side of the hinged door 222 away from the rotation axis thereof.
When the hinged door 222 is provided with one sealing strip, and the hinged door 222 is provided with the sealing strip on one side far away from the rotating shaft, after the hinged door 222 closes the opening 221a, the sealing strip can seal the gap between the box 221 and one side far away from the rotating shaft of the hinged door 222, so that the protection effect of the second charging contact 210 is further improved. When two hinged doors 222 are provided, and when sealing strips are provided on one side of the hinged doors 222 away from the rotating shaft, after the hinged doors 222 close the opening 221a, the sealing strips on the two hinged doors 222 can seal the gap between the two hinged doors 222, so that the protection effect on the second charging contact 210 is further improved as well.
To facilitate contact between the first charging contact 120 and the second charging contact 210, the second charging contact 210 may be disposed over a sidewall of the case 221 opposite to the opening 221 a. By fully distributing the second charging contact 210 on the side wall of the case 221 opposite to the opening 221a, the dimensions of the positive electrode and the negative electrode of the second charging contact 210 are set larger, so as to increase the contact area of the second charging contact 210 with the first charging contact 120, thereby ensuring that the first charging contact 120 can effectively contact with the second charging contact 210, and avoiding the risk of poor contact.
