Description

Technical Field

[0001] The present invention relates to the technical field of intelligent robots, and in particular to a micro-motion adjustable charging head for a robot charging pile. Background Art

[0002] With the development of intelligent robots, various service robots have emerged, such as sweepers, tour guides, shopping guide robots, consulting robots, etc. People have higher and higher requirements for robots' long-term duty, increased range of activities, and extended autonomy time. Therefore, replenishing power energy has become a problem that needs to be solved urgently.

[0003] At present, the charging method of charging piles is adopted by many companies as an excellent charging solution. When the power of the robot drops to a set value, it automatically returns to the charging pile for charging, and continues to work or standby after charging is completed. However, alignment errors usually occur when the robot returns to the pile, which may cause the robot to fail to return to the pile and charge normally. If it is not aligned before the power is exhausted, it has to be manually aligned and charged, which is time-consuming and laborious. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems existing in the prior art and provide a micro-motion adjustable charging head for a robot charging pile.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] A micro-motion adjustable charging head for a robot charging pile comprises a charging pile and a charging head electrically connected to the charging pile and providing a charging port. The charging head is connected to the charging pile via a spring to provide universal micro-motion freedom for the charging head. The charging port of the charging head is provided with positive and negative contact electrodes for contacting and charging with corresponding robot charging contacts and micro-adjusting the alignment error generated when the robot returns to the pile.

[0007] Furthermore, the front end surface of the charging head is provided with positive and negative contact electrodes, the rear end surface of the charging head is connected to one end of a spring, the other end of the spring is connected to a support, and the support is connected to the charging pile.

[0008] Furthermore, one end of a movable rotating shaft is connected to the charging head, and the other end of the movable rotating shaft passes through the inner side of the spring and extends to the support. A photoelectric sensor is provided on the support, and the photoelectric sensor cooperates with the other end of the movable rotating shaft. When the robot returns to the charging pile and contacts the positive and negative poles in alignment, the movable rotating shaft is pushed to trigger the photoelectric sensor.

[0009] Furthermore, an anti-full-retraction gasket and a corresponding threaded fastener are provided on the portion of the movable shaft extending to the outside of the support to prevent the movable shaft from being fully retracted and falling out of the support.

[0010] Furthermore, a limiting groove is provided on the surface of the charging pile opposite to the charging head, and the limiting groove cooperates with the corresponding raised portion on the charging head to limit the charging head in the forward and backward extension direction.

[0011] The beneficial effects of the present invention are:

[0012] The present invention adopts a spring-type universal adjustment structure, which can automatically adjust the alignment error generated when the robot returns to the pile, thereby avoiding the problem that the robot fails to return to the pile in place at one time.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] like Figures 1 to 4 As shown, a micro-motion adjustable charging head for a robot charging pile includes a charging pile 7, and a charging head 1 electrically connected to the charging pile 7 and providing a charging port. The charging head 1 is connected to the charging pile 7 via a spring 3, which is used to provide universal micro-motion freedom for the charging head 1. The charging port of the charging head 1 is provided with positive and negative contact electrodes 8, which are used to contact and charge with corresponding robot charging contacts, and micro-adjust the alignment error generated when the robot returns to the pile.

[0020] The front end surface of the charging head 1 is provided with positive and negative contact electrodes 8, the rear end surface of the charging head 1 is connected to one end of the spring 3, the other end of the spring 3 is connected to a support 5, and the support 5 is connected to the charging pile 7.

[0021] One end of the movable shaft 2 is also connected to the charging head 1, and the other end of the movable shaft 2 passes through the inner side of the spring 3 and extends to the support 5. The support 5 is provided with a photoelectric sensor 6, and the photoelectric sensor 6 cooperates with the other end of the movable shaft 2. When the robot returns to the charging pile and aligns with the positive and negative poles 8, the movable shaft 2 is pushed to trigger the photoelectric sensor 6. In this embodiment, an installation plate is provided on the charging pile 7 for docking and installation with the support 5 or the photoelectric sensor 6. In this embodiment, in order to completely not affect the deformation fine-tuning of the spring 3, the movable shaft 2 adopts a two-section structure. The first section of the movable shaft 2 is connected to the charging head 1, and the second section of the movable shaft 2 is extended and connected to the support 5. The first section of the movable shaft 2 and the second section of the movable shaft 2 are connected by an elastic member (such as a small spring). When the robot returns to the charging pile and aligns with the positive and negative poles 8, the charging head 1 drives the first section of the movable shaft 2 to push the second section of the movable shaft 2, and the second section of the movable shaft 2 triggers the photoelectric sensor 6. In this way, the charging can be triggered normally without affecting the deformation fine-tuning of the spring 3 at all.

[0022] An anti-full-retraction gasket and corresponding threaded fasteners are provided on the portion of the movable shaft 2 extending to the outside of the support 5 to prevent the movable shaft 2 from being fully retracted and falling out of the support 5 .

[0023] A limiting groove 4 is provided on the surface of the charging pile 7 opposite to the charging head 1. The limiting groove 4 cooperates with the corresponding raised portion on the charging head 1 to limit the charging head 1 in the forward and backward extension direction. In the present embodiment, the raised portion on the charging head 1 is a hollow cylindrical structure, the hollow portion can pass a wire, and the limiting groove 4 is a full-through groove.

[0024] Principle of the Invention

[0025] In the present invention, when the robot returns to the charging pile for charging, the movable rotating shaft 2 and the spring 3 are acted upon by the robot, and the charging head 1 is fine-tuned up, down, left and right so that the positive and negative electrodes 8 are aligned and in contact with the charging contacts of the robot, and then the photoelectric sensor 9 is triggered, the charging pile starts to work, the circuit is connected, the display light lights up, and the robot starts to enter the charging mode.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
