These robots significantly improve work efficiency and accuracy by automatically handling goods. To ensure the continuous operation of the robots, an automatic charging system has become an essential part of them.

[0003] However, there are some technical problems in the existing automatic charging system when charging wheeled cargo handling robots. One of the main problems is that due to insufficient movement accuracy, when the robot docks with the charging interface, the charging plug may be inserted too deeply into the charging probe, causing damage or deformation of the probe. This damage not only affects the charging efficiency but also may pose a safety hazard. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a structure of an automatic charging pile for a mobile robot to solve the problem that the charging probe of the mobile robot is easily damaged in view of the above-mentioned deficiencies in the existing technology.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is: a structure of an automatic charging pile for a mobile robot, including a charging pile main body, a male charging pile installed on the front side of the charging pile main body, and a charging probe installed on the male charging pile. The male charging pile and the charging pile main body are connected by a first elastic telescopic mechanism, the telescopic direction of the first elastic telescopic mechanism is the front-back direction, and the charging probe faces the front side.

[0006] For the above-mentioned structure of the automatic charging pile for a mobile robot, the first elastic telescopic mechanism includes a guiding plug and a first spring. The first spring is sleeved on the guiding plug. The tail end of the guiding plug is fixed on the charging pile main body. The connecting hole on the male charging pile is sleeved on the guiding plug. The head end of the guiding plug limits the front side of the connecting hole. The first spring is clamped between the charging male head and the charging pile main body.

[0007] For the above-mentioned structure of the automatic charging pile for a mobile robot, the charging probe includes a probe head and a second elastic telescopic mechanism. The probe head is installed on the male charging pile through the second elastic telescopic mechanism, and the telescopic direction of the second elastic telescopic mechanism is the front-back direction.

[0008] The above-mentioned automatic charging pile structure for a mobile robot, wherein the second elastic telescopic mechanism includes a conduit fixed to the male charging pile head, a probe rod inserted into the conduit, and a second spring sleeved on the probe rod. The probe head is fixed to the front end of the probe rod, and the second spring is clamped between the rear end of the probe head and the front end of the conduit. The rear end of the probe rod is provided with a limiting member to prevent the probe rod from being pulled out from the front side of the conduit.

[0009] The above-mentioned automatic charging pile structure for a mobile robot, wherein the rear end of the probe rod extends outside the rear end of the conduit. The segment of the probe rod near the rear end has a threaded structure, and the limiting member is a nut, which is threadedly installed on the probe rod.

[0010] The utility model has the following advantages compared with the prior art:

[0011] 1. Improve the docking accuracy: Through the setting of the first elastic telescopic mechanism, the male charging pile head can elastically expand and contract in the front and rear directions, so as to more flexibly adapt to the movement error of the robot. This design can significantly improve the charging docking accuracy and reduce collisions and damages caused by position offsets.

[0012] 2. Reduce the over-insertion of the charging plug: The elastic telescopic mechanism allows the charging probe to move back and forth within a certain range, so as to automatically adjust the position when the robot approaches the charging pile, avoid the over-insertion of the charging plug into the charging probe, and reduce the direct impact and damage to the probe.

[0013] 3. Enhance the charging safety: The design of the elastic telescopic mechanism not only improves the docking flexibility, but also enhances the safety during the charging process. During the docking process of the robot, even if a slight collision occurs, the elastic mechanism can absorb part of the impact force and protect the charging probe from damage.

[0014] 4. Reduce the maintenance cost: Reducing the damage frequency of the charging probe can significantly reduce the maintenance cost caused by repairing and replacing the charging probe. The buffering effect of the elastic telescopic mechanism reduces the hard collision and prolongs the service life of the charging probe.

[0015] In summary, the utility model not only solves the key problems in the existing automatic charging system, but also improves the efficiency and reliability of the entire charging process, providing strong support for the wide application of wheeled cargo handling robots.

[0016] Next, through the drawings and embodiments, the technical solutions of the utility model will be further described in detail. Brief Description of the Drawings

[0027] As Figure 1 — Figure 4 As shown in the figure, a mobile robot automatic charging pile structure includes a charging pile main body 1, a male charging connector 2 installed on the front side of the charging pile main body 1, and a charging probe 3 installed on the male charging connector 2. The male charging connector 2 and the charging pile main body 1 are connected by a first elastic telescopic mechanism 4. The telescopic direction of the first elastic telescopic mechanism 4 is the front-back direction, and the charging probe 3 faces the front side.

[0028] In this embodiment, the number of the first elastic telescopic mechanisms 4 is four, and the four first elastic telescopic mechanisms 4 are distributed at the four corners of the male charging connector 2.

[0029] By providing the first elastic telescopic mechanism 4 between the male charging connector 2 and the charging pile main body 1, the male charging connector 2 is allowed to elastically expand and contract in the front-back direction. This design improves the flexibility and accuracy of charging docking, and reduces collisions and damages caused by insufficient movement accuracy of the robot during automatic charging.

[0030] As Figure 3 As shown in the figure, in this embodiment, the first elastic telescopic mechanism 4 includes a guide plug 4-1 and a first spring 4-2. The first spring 4-2 is sleeved on the guide plug 4-1. The tail end of the guide plug 4-1 is fixed on the charging pile main body 1. The connection hole on the male charging connector 2 is sleeved on the guide plug 4-1. The head end of the guide plug 4-1 limits the front side of the connection hole. The first spring 4-2 is clamped between the charging male connector and the charging pile main body 1.

[0031] The specific implementation of the first elastic telescopic mechanism 4 includes a guide plug 4-1 and a first spring 4-2. This structure not only provides the elastic telescopic function, but also enhances the stability and durability of the mechanism through the cooperation of the guide plug 4-1 and the first spring 4-2.

[0032] As Figure 4 shown, in this embodiment, the charging probe 3 includes a probe head 3-1 and a second elastic telescopic mechanism. The probe head 3-1 is installed on the male charging pile 2 through the second elastic telescopic mechanism, and the telescopic direction of the second elastic telescopic mechanism is the front-back direction.

[0033] In this embodiment, the number of the charging probes 3 is sixteen.

[0034] The charging probe 3 is installed on the male charging pile 2 through the second elastic telescopic mechanism. This design allows the probe head 3-1 to elastically expand and contract in the front-back direction. This not only improves the adaptability of the charging probe 3, but also reduces the over-insertion and damage caused by the movement error of the robot.

[0035] In this embodiment, the second elastic telescopic mechanism includes a conduit 3-2 fixed to the male charging pile 2, a probe rod 3-3 inserted into the conduit 3-2, and a second spring 3-4 sleeved on the probe rod 3-3. The probe head 3-1 is fixed to the front end of the probe rod 3-3. The second spring 3-4 is clamped between the rear end of the probe head 3-1 and the front end of the conduit 3-2. The rear end of the probe rod 3-3 has a limiting member 3-5 to prevent the probe rod 3-3 from being pulled out from the front side of the conduit 3-2.

[0036] The second elastic telescopic mechanism includes a conduit 3-2, a probe rod 3-3 and a second spring 3-4. This structural design enables the probe head 3-1 to flexibly expand and contract, and at the same time provides an appropriate elastic force through the second spring 3-4. The design of the limiting member 3-5 of the probe rod 3-3 prevents the probe rod 3-3 from being pulled out from the front side of the conduit 3-2, enhancing the safety and durability of the charging probe 3.

[0037] In this embodiment, the rear end of the probe rod 3-3 extends outside the rear end of the conduit 3-2. The segment of the probe rod 3-3 near the rear end has a threaded structure. The limiting member 3-5 is a nut, and the limiting member 3-5 is threadedly installed on the probe rod 3-3.

[0038] The design of the rear end of the probe rod 3-3 and the specific implementation of the limiting member 3-5 further enhance the stability and safety of the charging probe 3. The threaded structure at the rear end of the probe rod 3-3 and the nut limiting member 3-5 provide a reliable fixing method, preventing the probe rod 3-3 from accidentally shifting or falling off during the charging process, and can also adjust the length of the probe rod 3-3 extending from the front end of the catheter 3-2. This design ensures the stability and reliability of the charging probe 3 during use.

[0039] The above are only the preferred embodiments of the present invention, and do not impose any limitations on the present invention. Any simple modifications, changes, and equivalent structural changes made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
