On the contrary, they are merely examples of methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0047] The terms used in the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The singular forms "a", "the" and "said" used in the present disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0048] Please refer to Figures 1-5, this embodiment discloses a charging device with a safety protection function, including a charging pile body 1, a charging component 2, a left and right protection component 3, and an upper and lower protection component 4. Among them, a charging shell 11 connected to the charging pile body 1 is provided on one side of the charging pile body 1, and the charging component 2 is provided on the charging pile body 1, and can be extended or retracted relative to the charging shell 11. The left and right protection components 3 are arranged in the charging pile body 1, and are transmission-connected to the charging component 2, and can be expanded or retracted according to the extension or retraction of the charging component 2. The upper and lower protection components 4 are arranged at the opening of the charging shell 11, and can open or close the charging shell 11 according to the extension or retraction of the charging component 2.

[0049] In the initial state, the upper and lower protection components 4 are closed to protect the entire charging device. Figure 3 When charging is required, the robot moves to the charging device with safety protection function, and then sends instructions to the charging device with safety protection function. After receiving the charging instruction, the charging device with safety protection function extends the charging component 2 toward the outer charging shell 11, and pushes the upper and lower protection components 4 to open during the extension process. At the same time, the left and right protection components 3 gradually expand to the left and right sides during the extension process of the charging component 2 (as shown in FIG. Figure 4 After the deployment is completed, the charging component 2 drives the left and right protection components 3 to approach the charging slot of the robot until the charging component 2 is inserted into the charging slot (as shown in FIG. Figure 5 As shown), the left and right protection components 3 then shield and protect the charging slot to prevent people from accidentally touching it and causing electric shock, thereby improving the safety factor. The left and right protection components 3 and the upper and lower protection components 4 can move with the charging component 2 without the need for additional power, with a simple structure and easy operation.

[0050] Further preferably, the charging assembly 2 includes a driving mechanism 21, a connecting frame 22, a charging head 23, a guide rod 24 and a spring column 25. The driving mechanism 21 is arranged inside the charging pile body 1, the connecting frame 22 is arranged at the transmission end of the driving mechanism 21, and the charging head 23 is arranged on the connecting frame 22 away from the driving mechanism 21 and opposite to the charging shell 11.

[0051] When a charging command is received, the driving mechanism 21 drives the charging head 23 to move towards the charging slot of the robot. The driving mechanism 21 is one of an electric push rod, a cylinder, and an oil cylinder. In this embodiment, the driving mechanism 21 selects an electric push rod, and its transmission end is a push rod. The guide rod 24 is arranged inside the charging pile body 1 and is used to guide the charging head 23 to perform a linear motion, so that the charging head 23 can more smoothly enter the charging slot to charge the robot, improving the driving efficiency. Specifically, two guide rods 24 are arranged. The two guide rods 24 are respectively located on both sides of the electric push rod. One end of each guide rod 24 is connected to the connecting frame 22, and the other end is connected to a linear bearing seat arranged inside the charging pile body 1, which can better ensure that the charging head 23 performs a linear motion.

[0052] The spring column 25 is arranged between the connecting frame 22 and the charging head 23. When the charging head 23 is docked with the charging slot, the spring column 25 can provide buffering for the charging head 23, convert hard contact into soft contact, reduce the wear of the charging head 23, reduce the damage probability of the charging head 23, and ensure the working efficiency.

[0053] Further preferably, the left and right protection components 3 include a left protection plate 31, a first reset member 32, a right protection plate 33, a second reset member 34, and two pressing plate mechanisms 35. Among them, the left protection plate 31 is hinged to the left side of the connecting frame 22 through the first reset member 32, and the right protection plate 33 is hinged to the right side of the connecting frame 22 through the second reset member 34. When the first reset member 32 and the second reset member 34 are in the initial state, the left protection plate 31 and the right protection plate 33 are opened. The two pressing plate mechanisms 35 are respectively arranged on the left and right sides of the inner cavity of the charging shell 11 and can be respectively tangent to the backs of the left protection plate 31 and the right protection plate 33 for pressing the left protection plate 31 and the right protection plate 33 flat.

[0054] Specifically, when the charging device does not receive a charging command, both the left and right protection components 3 and the charging component 2 are inside the charging pile body 1. At this time, the left protection plate 31 and the right protection plate 33 are flush with the left and right sides of the connecting frame 22 under the action of the pressing plate mechanism 35, as Figure 6 shown. When the charging device receives a charging command, the charging component 2 drives the left and right protection components 3 to extend out of the charging pile body 1. When the left protection plate 31 and the right protection plate 33 lose the acting force of the pressing plate mechanism 35, the left protection plate 31 and the right protection plate 33 are unfolded under the action of the first reset member 32 and the second reset member 34, so as to protect the opening area of the charging slot, as Figure 7 and Figure 8 shown. The unfolding area of the left protection plate 31 and the right protection plate 33 is larger than the opening area of the charging slot. Even if the robot has a left-right deviation of ±40 mm from the charging pile in positioning, it can still play a good protective role. In this embodiment, both the first reset member 32 and the second reset member 33 select torsion spring hinges, which have a simple structure and are convenient to assemble.

[0055] Further preferably, the pressing plate mechanism 35 includes a mounting base 351 and a roller 352. Among them, the mounting base 351 is arranged inside the charging case 11, the roller 352 is rotatably connected to one side of the mounting base 351 close to the charging case 11, and can be tangent to the back of the left protection plate 31 or the right protection plate 33. When the charging pile is in the closed state, the end of the left protection plate 31 or the right protection plate 33 abuts against the roller 352 (as Figure 6 shown). During the extending process, the left protection plate 31 or the right protection plate 33 moves outward relative to the roller 23. When the left protection plate 31 or the right protection plate 33 is disengaged from the action of the roller 352, it bounces open to the left and right under the action of the torsion spring hinge (as Figure 7 shown). During the contraction process, the connection part of the left protection plate 31 or the right protection plate 33 and the torsion spring hinge first contacts the roller 352, and then gradually drives the left protection plate 31 or the right protection plate 33 to close under the action of the roller 352, that is, flush with both sides of the connecting frame 22 until the left protection plate 31 or the right protection plate 32 is completely retracted into the interior of the charging pile body 1. At this time, the end of the left protection plate 31 or the right protection plate 33 abuts against the roller 352.

[0056] Limit members 36 opposite to the backs of the left protection plate 31 and the right protection plate 33 are respectively arranged on the left and right sides of the connecting frame 22. The limit members 36 can limit the unfolding angle of the left protection plate 31 or the right protection plate 33. In this embodiment, the unfolding angle is 90°.

[0057] Please refer to Figure 9 , the upper and lower protection assembly 4 includes an upper protection plate 41, a lower protection plate 42, a first connecting part 43, a second connecting part 44 and a third reset member 45. Among them, the upper protection plate 41 is arranged on the upper part of the charging case 11, the lower protection plate 42 is arranged on the lower part of the charging case 11, the lower protection plate 43 and the upper protection plate 41 can seal the charging case 11. One end of the first connecting part 43 is fixedly connected to the upper protection plate 41, and the other end is rotatably connected to the top of the inner side wall of the charging case 11. One end of the second connecting part 44 is fixedly connected to the lower protection plate 42, and the other end is rotatably connected to the bottom of the inner side wall of the charging case 11. There are two third reset members 45. One ends of the two third reset members 45 are respectively connected to the first connecting part 43 and the second connecting part 44, and the other ends are respectively connected to the top and the bottom of the inner side wall of the charging case 11. When the third reset member 45 is in the initial state, the upper protection plate 41 and the lower protection plate 42 are closed.

[0058] During the process of the charger head 23 extending out, the charger head 23 pushes out the upper protection plate 41 and the lower protection plate 42. The upper protection plate 41 and the lower protection plate 42 are unfolded up and down under the action of the first connecting portion 43 and the second connecting portion 44. The side wall of the connecting frame 22 blocks the upper protection plate 41 and the lower protection plate 42 to prevent them from closing. When the charger head 23 retracts into the charging pile body 1, the upper protection plate 41 and the lower protection plate 42 lose the blocking force of the side wall of the connecting frame 22 and return under the action of the third reset member 45, thereby closing the charging shell 11.

[0059] In this embodiment, both the first connecting portion 43 and the second connecting portion 44 are U-shaped connecting members, and the third reset member 45 is a tension spring. One end of the U-shaped connecting member is rotatably connected to the charging shell 11, and the other end is fixedly connected to the upper protection plate 41 or the lower protection plate 42. The outer side surface of the U-shaped connecting member is connected to one end of the tension spring, and the other end of the tension spring is connected to the inner side wall of the charging shell 11. When the upper protection plate 41 and the lower protection plate 42 are unfolded, it will drive the tension spring to stretch. When the upper protection plate 41 and the lower protection plate 42 lose the blocking force of the connecting frame 22, the upper protection plate 41 and the lower protection plate 42 are closed under the action of the restoring force of the tension spring.

[0060] Compared with the prior art, the charging device with a safety protection function of the present invention improves the safety factor by providing the left and right protection components 3 and the up and down protection components 4 to protect the working state and the non-working state of the charging component 2 respectively. Moreover, the left and right protection components 3 and the up and down protection components 4 can move following the movement of the charging component 2 without additional power, with a simple structure and convenient operation. By the mutual cooperation of the left protection plate 31 and the right protection plate 32 to protect the charger head 23, the risk of electric shock caused by a person reaching into the charging groove from both sides is reduced, and the safety factor is improved. By providing the spring column 25, the charger head 23 and the robot charging groove are in soft contact, reducing the damage during charging docking. The charging device with a safety protection function of the present invention has the characteristics of high safety factor and the like.

[0061] The above-described embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
