[0028] In order to solve the problems in the prior art, the present application provides a charging component and a charging pile. The first charging brush block of the charging component can be adaptively adjusted through an elastic part, and maintains full contact with the second charging brush block of the robot under the action of the elastic part, thereby reducing contact resistance, avoiding heating of the charging brush block, and extending service life.

[0029] Figure 1 shows a schematic structural diagram of a charging assembly provided in an embodiment of the present application; Figure 2 shows a schematic structural diagram of a first charging brush block and an elastic member provided in an embodiment of the present application; Figure 3 shows a schematic structural diagram of an exploded structure of a charging assembly provided in an embodiment of the present application; Figure 4 shows a schematic structural diagram of a first charging brush block provided in an embodiment of the present application when docked with a second charging brush block of a robot.

[0030] As shown in Figures 1-4, an embodiment of the present application provides a charging assembly, including: a mounting base 1, having a mounting surface 11; and a first charging brush block 2, the first charging brush block 2 is movably set on the mounting surface 11 of the mounting base 1 through an elastic member 3, so that the plane where the first charging brush block 2 is located is set at an angle to the mounting surface 11, the first charging brush block 2 has a charging part 21, the charging part 21 is used to dock with the second charging brush block 4 of the charging device, the charging part 21 of the first charging brush block 2 has a first tooth-shaped structure 211, the second charging brush block 4 has a second tooth-shaped structure 41 that engages with the first tooth-shaped structure 211, a first tooth groove 212 for accommodating the second tooth-shaped structure 41 is formed between two adjacent first tooth-shaped structures 211, and the first tooth groove 212 is gradually expanded toward the opening direction; a second tooth groove 42 for accommodating the first tooth-shaped structure 211 is formed between two adjacent second tooth-shaped structures 41, and the second tooth groove 42 is gradually expanded toward the opening direction.

[0031] In the present application, the first charging brush block 2 is movably set. When docking with the second charging brush block 4 of the robot, if the positioning or movement of the robot deviates, the first charging brush block 2 can be adaptively adjusted through the elastic member 3, and maintain full contact with the second charging brush block 4 of the robot under the action of the elastic member 3, thereby reducing the contact resistance. The first tooth-shaped structure 211 of the first charging brush block 2 is engaged with the second tooth-shaped structure 41 of the second charging brush block 4. Because the contact surface is tooth-shaped, the contact area can be further increased, thereby avoiding the first charging brush block 2 and the second charging brush block 4 from heating up, avoiding overheating of the charging brush blocks, and extending the service life.

[0032] In the related art, many robots, such as cleaning robots, have the function of automatic charging, that is, they will automatically move to the charging pile for charging when they need to be charged. During charging, the second charging brush block 4 of the robot docks with the first charging brush block 2 of the charging pile to transmit current. However, there will be deviations in the positioning angle or movement of the robot each time. When the robot approaches the charging pile to dock the charging brush block, the charging brush block will not be fully in contact because the robot is not aligned. Only a small part of it is in contact. The reduction in the contact part will increase the contact resistance, which will cause the charging brush block to heat up. The heating of the charging brush block will not only affect the service life of the charging brush block, but also increase the temperature around the charging brush block, affecting the service life of some accessories, such as causing the aging of plastic materials.

[0033] Specifically, the first charging brush block 2 is connected to the mounting base 1 via the elastic member 3, so that the first charging brush block 2 can be adjusted in pitch or in left and right swing, or in both pitch angle adjustment and left and right swing adjustment.

[0034] Specifically, a mounting groove 12 is provided on the mounting surface 11 of the mounting base 1, and one end of the first charging brush block 2 is inserted into the mounting groove 12, and the inner diameter of the mounting groove 12 is larger than the outer dimension of the first charging brush block 2, thereby allowing the angle of the first charging brush block 2 to be adjusted within a certain range.

[0035] In the present application, the first tooth groove 212 and the second tooth groove 42 adopt a gradually expanding design, which facilitates the first tooth-shaped structure 211 and the second tooth-shaped structure 41 to complete the insertion, and facilitates successful docking when the insertion contacts.

[0036] In the embodiment of the present application, the first charging brush block 2 of the charging assembly is configured to be movable, and the first charging brush block 2 is supported by the elastic member 3. When the robot is docked, there is no deviation, and the charging assembly is pushed vertically by the robot, ensuring that the second charging brush block 4 of the robot maintains good contact with the first charging brush block 2 of the charging assembly. If the robot deviates slightly to the right, the first charging brush block 2 of the charging assembly will tilt toward the right; if the robot deviates slightly to the left, the first charging brush block 2 of the charging assembly will tilt toward the left. Regardless of how the robot docks, the second charging brush block 4 of the robot can be in parallel contact with the first charging brush block 2 of the charging assembly, thereby ensuring that the second charging brush block 4 and the first charging brush block 2 are in full contact, so that the resistance does not increase and the occurrence of heat is avoided.

[0037] In some embodiments, the elastic member 3 is a spring, one end of the spring is connected to the first charging brush block 2 , and the other end is connected to the mounting base 1 .

[0038] In the present application, the two ends of the spring are respectively connected to the first charging brush block 2 and the mounting base 1, so that the elastic member 3 can not only play the role of elastic support when the first charging brush block 2 and the second charging brush block 4 are docked, ensuring that the first charging brush block 2 and the second charging brush block 4 are in full contact; but also support the first charging brush block 2 in normal times to ensure the stability of the first charging brush block 2.

[0039] Specifically, the length of the elastic member 3 is relatively short, which can effectively support the first charging brush block 2. The angle of the first charging brush block 2 can be adjusted within a certain angle range. Because the offset angle or displacement of the robot will not be too large, it is only necessary for the first charging brush block 2 to be tilted and adjusted within a range.

[0040] In the present application, a fixing column is provided on the first charging brush block 2, which is connected to the spring through the fixing column to complete the connection between the spring and the first charging brush block 2. The fixing column can be provided with an insulating member for insulation treatment.

[0041] In some embodiments, there are four elastic members 3 , which are respectively disposed at the four end corners of the first charging brush block 2 .

[0042] In the present application, elastic members 3 are respectively provided at the four end corners of the first charging brush block 2 to ensure the support effect of the first charging brush block 2, and the first charging brush block 2 can be tilted in multiple directions to adapt to robots offset in different directions.

[0043] In some embodiments, a mounting groove 12 for accommodating the first charging brush block 2 is provided on the mounting surface 11 of the mounting base 1 .

[0044] In the present application, because the robot only faces, deflects to the left, and deflects to the right when performing charging docking, the first charging brush block 2 only needs to swing left and right.

[0045] Specifically, the upper and lower surfaces of the first charging brush block 2 are in contact with the inner top surface and inner bottom surface of the mounting groove 12, respectively, to support the first charging brush block 2. A gap is left between the left and right ends of the first charging brush block 2 and the left and right side walls of the mounting groove 12, so that the first charging brush block 2 can be swung left and right.

[0046] In some embodiments, a plurality of first charging brush blocks 2 are provided on the mounting surface 11 of the mounting base 1 .

[0047] In the present application, the number of the first charging brush blocks 2 is determined according to actual conditions. Specifically, the present application provides four first charging brush blocks 2. The four first charging brush blocks 2 are respectively in contact with the four second charging brush blocks 4 of the robot to complete the charging connection. The four first charging brush blocks 2 are all movably arranged on the mounting base 1 through elastic members 3, so that the four first charging brush blocks 2 can be adjusted synchronously during connection to ensure the reliability of the connection.

[0048] In some embodiments, a seal 13 for cooperating with a charging device is provided on the mounting surface 11 of the mounting base 1 , and the first charging brush block 2 is located inside the seal 13 .

[0049] In the present application, when the charging device is docked with the charging assembly for charging, the seal 13 abuts against the charging device, thereby enclosing the first charging brush block 2 and the second charging brush block 4 in a relatively closed space, preventing external influences during the charging process and further improving the reliability of charging.

[0050] In some embodiments, a first tooth groove 212 for accommodating the second tooth structure 41 is formed between two adjacent first tooth-shaped structures 211, and the first tooth groove 212 is gradually expanded toward the opening direction; a second tooth groove 42 for accommodating the first tooth-shaped structure 211 is formed between two adjacent second tooth-shaped structures 41, and the second tooth groove 42 is gradually expanded toward the opening direction.

[0051] In some embodiments, the first tooth-shaped structure 211 is an isosceles triangle or an isosceles trapezoid; the second tooth-shaped structure 41 is an isosceles triangle or an isosceles trapezoid.

[0052] In the present application, by setting the first tooth-shaped structure 211 and / or the second tooth-shaped structure 41 to an isosceles trapezoid or an isosceles triangle, it is ensured that the first tooth-shaped structure 211 and the second tooth-shaped structure 41 can fully engage when docking, thereby ensuring sufficient contact.

[0053] In some embodiments, the first charging brush block 2 is detachably mounted on the mounting base 1 .

[0054] In the present application, when the first charging brush block 2 and the second charging brush block 4 are aligned, extrusion wear between one side will occur at the junction of the first tooth-shaped structure 211 and the second tooth-shaped structure 41, and the first charging brush block 2 can be movably set in the installation groove 12 through the elastic member 3. The elastic member 3 provides elastic force for the first charging brush block 2, so that the first charging brush block 2 can fully abut against the second charging brush block 4 of the charging device to ensure the reliability of the connection, and can also avoid the rigid wear of the first tooth-shaped structure 211 and the second tooth-shaped structure 41, reduce the wear between the first charging brush block 2 and the second charging brush block 4, and the first charging brush block 2 can be replaced after severe wear.

[0055] The charging component is movably arranged through the first charging brush block 2. When docking with the second charging brush block 4 of the robot, if the positioning or movement of the robot deviates, the first charging brush block 2 can be adaptively adjusted through the elastic member 3, and maintain full contact with the second charging brush block 4 of the robot under the action of the elastic member 3, thereby reducing the contact resistance. The first tooth-shaped structure 211 of the first charging brush block 2 is engaged with the second tooth-shaped structure 41 of the second charging brush block 4. Because the contact surface is tooth-shaped, the contact area can be further increased, thereby avoiding the first charging brush block 2 and the second charging brush block 4 from heating up, avoiding overheating of the charging brush blocks, and extending the service life.

[0056] An embodiment of the present application provides a charging pile, comprising: a pile body; and the above-mentioned charging component, wherein a mounting base of the charging component is arranged on the pile body.

[0057] In a possible implementation, a dust cover 5 is provided between the mounting base 1 and the pile body.

[0058] In the present application, the dust cover 5 forms a relatively sealed space between the mounting base 1 and the pile body, thereby providing dustproof protection for some connecting joints on the mounting base 1 .

[0059] In this application, when the robot is charging, it moves to the charging pile and moves vertically toward the charging pile. However, there are deviations in the positioning and movement of the robot. When the robot has deviations, the second charging brush block 4 of the robot will push the first charging brush block 2 to perform adaptive adjustment when it abuts against the first charging brush block 2, ensuring that the surface of the first charging brush block 2 can remain parallel to the surface of the second charging brush block 4, thereby ensuring that the first charging brush block 2 is in full contact with the second charging brush block 4, thereby avoiding the phenomenon of heating of the first charging brush block 2 and the second charging brush block 4 due to increased contact resistance.
