In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0040] Combination Figures 1 to 3 As shown, the charging pile according to the embodiment of the first aspect of the utility model includes a shell 100 and a charging contact 200, the shell 100 is provided with a charging slot 110; the charging contact 200 is slidably connected to the charging slot 110 along a set direction, one of the charging contact 200 and the charging slot 110 is provided with a first limiting portion 210, and the other is provided with a second limiting portion 111, and the second limiting portion 111 has a first limiting surface 112 and a second limiting surface 113 which are arranged oppositely; when the first limiting portion 210 cooperates with the first limiting surface 112, the charging contact 200 is in the first extreme position, and when the first limiting portion 210 cooperates with the second limiting surface 113, the charging contact 200 is in the second extreme position.

[0041] According to the charging pile of the embodiment of the utility model, the charging contact 200 is connected to the charging slot 110, the first limiting portion 210 abuts against the first limiting surface 112, the charging contact 200 is farthest from the bottom surface of the charging slot 110 along the set direction, is in the first limit position, and cannot move further away from the charging slot 110; the charging contact 200 moves along the set direction until the first limiting portion 210 abuts against the second limiting surface 113, the charging contact 200 is closest to the bottom surface of the charging slot 110 along the set direction, is in the second limit position, and cannot move further along the set direction.

[0042] It should be noted that when the charging pile is used to charge an object to be charged (such as a robot), the object to be charged usually needs to abut the charging contact 200 and push the charging contact 200 to a set position along a set direction. The charging pile controls the charging contact 200 to energize to charge the object to be charged.

[0043] The charging pile of the embodiment of the utility model is provided with a first limiting portion 210 and a second limiting portion 111 to cooperate with each other to achieve physical limiting between the charging contact 200 and the charging slot 110, which effectively improves the accuracy of the stroke control of the charging contact 200. The first limiting surface 112 prevents the charging contact 200 from sliding along the set direction and exceeding the charging slot 110 to collide with other components in the charging pile. The second limiting surface 113 prevents the charging contact 200 from falling out of the notch of the charging slot 110, which effectively improves the use experience of the charging pile; and when an elastic reset member 300 is provided between the charging contact 200 and the charging slot 110, the deformation of the reset member 300 can be controlled within a certain range without excessive deformation, thereby effectively improving the service life of the reset member 300.

[0044] In this embodiment, there are two charging contacts 200 corresponding to the charging slots 110, namely the positive contact and the negative contact. When the positive contact and the negative contact are in contact with the corresponding charging contacts on the object to be charged at the same time and the charging contact 200 of the charging pile is powered on, the object to be charged is charged. Of course, for multi-phase charging (such as three-phase charging), the number of charging slots 110 and charging contacts 200 can also be adaptively adjusted to meet the charging needs.

[0045] In this embodiment, the first limiting portion 210 is installed on the charging slot 110, and is a mounting block extending from the bottom of the charging slot 110 away from the set direction, and the mounting block extends a protrusion in the radial direction of the set direction; the second limiting portion 111 is provided on the charging contact 200, and the protrusion slides along the set direction and abuts against the first limiting portion 210 or the second limiting portion 111 of the second limiting portion 111. Of course, the first limiting portion 210 can also be installed on the charging contact 200, and the second limiting portion 111 can be provided in the charging slot 110 accordingly.

[0046] According to one embodiment of the utility model, combined Figure 3 As shown, the second limiting portion 111 includes a base 114, a connecting side wall 115 and a stopper 116. The base 114 and the stopper 116 are arranged opposite to each other. The base 114 forms a first limiting surface 112, and the stopper 116 forms a second limiting surface 113. An installation space 117 is formed between the base 114, the connecting side wall 115 and the stopper 116, and the first limiting portion 210 is located in the installation space 117.

[0047] In this embodiment, taking the second limiting portion 111 provided on the charging contact 200 as an example, when the charging contact 200 is installed from the outside to the charging slot 110, the stopper 116 first contacts the first limiting portion 210, and the first limiting portion 210 pushes the stopper 116 in a direction away from the opening of the installation space 117, and the stopper 116 drives the connecting side wall 115 to deviate from the opening side away from the installation space 117. After the stopper 116 passes through the first limiting portion 210, it is not pushed, and the connecting side wall 115 is reset in the direction of the opening of the installation space 117, thereby realizing the limiting connection between the first limiting portion 210 and the installation space 117, and the first limiting portion 210 is limited between the base 114 and the stopper 116.

[0048] By providing the connecting side wall 115 and the stopper 116, the staff can effectively install the charging contact 200 into the charging slot 110 from the outside by virtue of the deformation of the connecting side wall 115. This is different from the prior art method of installing the charging contact 200 from the inside of the charging pile to the outside of the charging pile, and the installation is more efficient and convenient.

[0049] certainly, Figure 3 The arrangement shown in the figure is that the second limiting portion 111 is provided on the charging contact 200, and the connecting side wall 115 of the second limiting portion 111 is used to deform to realize the installation of the charging contact 200 and the charging slot 110. In other embodiments, the second limiting portion 111 can also be provided in the installation slot, and the connecting side wall 115 of the second limiting portion 111 is used to deform to realize the connection between the charging contact 200 and the charging slot 110.

[0050] It is understandable that the connecting side wall 115 and the stopper 116 can also be set on the first limiting portion 210, and a mounting groove extending along a set direction is set corresponding to the stopper 116 of the first limiting portion 210 to form a second limiting portion 111 to achieve the connection between the charging slot 110 and the charging contact 200.

[0051] According to one embodiment of the utility model, combined Figure 1 As shown, the charging pile includes at least two second limiting parts 111, and the second limiting parts 111 are arranged along the length direction of the charging contact 200, and the first limiting parts 210 correspond to the second limiting parts 111. This ensures that the supporting force on the charging contact 200 as a whole is more uniform, avoids the problem of stagnation caused by too small supporting force on one side along the length direction, and effectively improves the stability of the movement of the charging contact 200.

[0052] In this embodiment, the length direction of the charging contact 200 extends along the left-right direction. Of course, when the charging contacts 200 are arranged in the up-down direction, the length direction is the up-down direction, which can be adaptively adjusted according to the actual arrangement of the charging contacts 200.

[0053] In this embodiment, two second limiting portions 111 are respectively provided above and below the charging contact 200; of course, the specific number and position of the second connection portions can be adjusted according to the actual length of the charging contact 200 in the length direction and the layout position of the interface on the charging contact 200 (such as the power supply line installation position 270).

[0054] In this embodiment, the power supply line installation position 270 is disposed at the end of the charging contact 200 along the length direction, which facilitates the power supply line to be routed outside the charging contact 200 and does not interfere with the movement of the charging contact 200 along the set direction.

[0055] According to one embodiment of the utility model, combined Figure 1 As shown, adjacent second limiting portions 111 are staggered and located on both sides of the charging contact 200 or the charging slot 110 in the length direction.

[0056] In the present embodiment, when a second limit portion is arranged above the charging contact 200, its adjacent second limit portion is located below the charging contact 200, and is asymmetrically arranged on both sides of the length direction of the charging contact 200, so that there is enough space between the first limit portion and the second limit portion in the direction perpendicular to the length. Compared with the charging contact 200 having the second limit portions symmetrically arranged on both sides of the length direction of the charging contact 200, the space required in the direction perpendicular to the length direction (the up and down direction in the present embodiment) is smaller, which is more conducive to the miniaturization of the charging pile.

[0057] According to one embodiment of the utility model, combined Figure 2 As shown, the charging contact 200 also includes a guide column 220 extending in a set direction; a limiting hole 118 is provided on the bottom surface of the charging slot 110, and the guide column 220 is slidably connected to the limiting hole 118. The limiting hole 118 ensures that the charging contact 200 is displaced within the constraint angle when moving, and ensures that the charging contact 200 will not collide with other components in the charging pile.

[0058] According to one embodiment of the utility model, combined Figure 2 As shown, the charging contact 200 is provided with a mounting groove 230, which is arranged around the end of the guide column 220 away from the limiting hole 118, and the notch of the mounting groove 230 faces the charging slot 110; the charging pile also includes a reset member 300, which is sleeved on the guide column 220, one end of the reset member 300 abuts against the bottom surface of the charging slot 110, and the other end is limited to the mounting groove 230.

[0059] In this embodiment, one end of the reset member 300 is limited and fixed by installing the annular groove 230. The staff only needs to put the reset member 300 on the guide column 220 and install the charging contact 200 to the charging slot 110. Due to the limiting effect of the first limiting portion 210 and the second limiting portion 111 between the charging slot 110 and the charging contact 200, the reset member 300 is always installed between the installing annular groove 230 and the charging slot 110 and will not fall out, thereby reducing the installation difficulty of the reset member 300 and effectively improving the production efficiency.

[0060] In this embodiment, the charging contact 200 is pressed by the object to be charged and slides along a set direction in the charging slot 110. The reset member 300 is deformed to resist the sliding of the charging contact 200 along the set direction, thereby achieving a close fit between the object to be charged and the charging contact 200 and ensuring the charging effect of the charging pile.

[0061] In this embodiment, the reset member 300 is a spring. Of course, the reset member 300 may also be a component with elastic deformation ability such as silicone, spring sheet, etc.

[0062] According to one embodiment of the utility model, combined Figure 2 As shown, the charging contact 200 includes a charging sheet 240 and a charging sheet bracket 250 . The charging sheet 240 is detachably connected to the charging sheet bracket 250 and is located on a side of the charging sheet bracket 250 away from the charging slot 110 .

[0063] In this embodiment, the charging plate bracket 250 is slidably connected to the charging slot 110. By separating the charging plate 240 and the charging plate bracket 250, the cost of replacing parts of the charging pile is reduced.

[0064] According to one embodiment of the utility model, combined Figure 1 and Figure 3 As shown, the charging pile also includes a detection member 400, which is arranged at the terminal end of the set direction and is suitable for detecting the position information of the charging contact 200. When the position information of the electric contact reaches the set position, the charging pile controls the charging contact 200 to be energized to realize charging of the object to be charged.

[0065] In one embodiment, in combination Figure 1 and Figure 2 As shown, the detection member 400 is a photoelectric sensor circuit board 411 , and the photoelectric sensor circuit board 411 is provided with a detection hole 412 ; the charging contact 200 is provided with a shielding portion 260 corresponding to the detection hole 412 , and the shielding portion 260 is suitable for being inserted into the detection hole 412 .

[0066] In this embodiment, after the shielding portion 260 is inserted into the detection hole 412, the light emitted by the transmitter of the photoelectric sensor circuit board 411 located on one side of the detection hole 412 cannot be received by the receiver arranged on the opposite side, indicating that the charging contact 200 has reached the set position and the charging contact 200 can be energized.

[0067] In this embodiment, a shielding portion 260 is separately provided on each of the two charging contacts 200, and two detection holes 412 are correspondingly provided on the photoelectric sensor circuit board 411; of course, the number of shielding portions 260 and detection holes 412 can be adjusted according to the number of charging contacts 200. For example, each charging contact 200 corresponds to a shielding portion 260 and a detection hole 412. When there is a linkage between the charging contacts 200 to ensure the same-direction movement, the shielding portion 260 and the detection hole 412 can also be provided on only one of the charging contacts 200.

[0068] In this embodiment, the shielding portion 260 is a shielding sheet, which helps to avoid collision with the detection hole 412. Of course, the shielding portion 260 can also be a shielding block, a shielding column, etc., which can be inserted into the detection hole 412 to achieve a shielding effect.

[0069] Of course, the detection component 400 can also be an infrared sensor, a gravity sensor or other detection component suitable for detecting the position of the object to be charged.

[0070] In this embodiment, the charging pile is also provided with a magnetic induction switch 420, which corresponds to the magnet set on the object to be charged. The magnetic induction switch 420 detects the magnet, indicating that the object to be charged at this time is the object to be charged corresponding to the charging pile, effectively preventing the charging pile from charging other objects and causing damage.

[0071] In this embodiment, two magnetic induction switches 420 are arranged in sequence on the photoelectric sensor circuit board 411 along the vertical direction, corresponding to the charging contacts 200, to avoid misdetection of one magnetic induction switch 420 and effectively ensure good contact between the object to be charged and the two charging contacts 200.

[0072] According to the second aspect of the present invention, the robot system includes:

[0073] The robot body and the charging pile as in the above embodiment, the charging pile is electrically connected to the robot body, and the charging pile is used to charge the robot body.

[0074] The beneficial effects of the robot system according to the embodiment of the utility model are similar to those of the charging pile in the embodiment of the first aspect of the utility model, and will not be described in detail here.

[0075] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
