Technical Field
[0001] The utility model relates to the technical field of robots, in particular to a charging pile and a robot system. Background Art
[0002] The charging contacts of the charging pile used by the robot are generally divided into positive contacts and negative contacts. In the prior art, the positive contacts and the negative contacts are stuck during the movement process, resulting in poor contact with the charging contacts of the robot body. Utility Model Content
[0003] The utility model aims to solve at least one of the technical problems existing in the related art. To this end, the utility model proposes a charging pile, which ensures the same-direction movement of the charging contacts by setting a linkage between the charging contacts, and when one of the charging contacts is stuck, the other charging contact can be assisted by the linkage to get out of the stuck position, effectively avoiding the problem of poor contact between the charging contacts and the charging contacts of the robot body.

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.
[0045] Combination Figures 1 to 4 As shown, the charging pile according to the embodiment of the first aspect of the utility model includes a shell 100, a charging contact 200 and a linkage member 400, the shell 100 is provided with two charging slots 110; the charging contacts 200 are installed in the charging slots 110 one by one, and a reset member 300 is provided between the charging contacts 200 and the charging slots 110, and the charging contacts 200 are suitable for sliding along a set direction during charging to deform the reset member 300; the two ends of the linkage member 400 are respectively connected to different charging contacts 200 so that the two linkage members 400 move in the same direction.
[0046] According to the charging pile of the embodiment of the utility model, the charging contact 200 is pressed by the object to be charged (such as a robot) and slides along the 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. The two charging contacts 200 are connected by a linkage member 400. The faster-moving charging contact 200 will drive the slower-moving charging contact 200 (the relative speed of the movement is reflected in a certain displacement difference between the two charging contacts 200) to move, thereby ensuring that the two charging contacts 200 always move in the same direction.
[0047] The charging pile of the embodiment of the utility model is provided with a linkage part 400. When one of the two charging contacts 200 gets stuck while sliding in the charging slot 110, resulting in inconsistent displacement between the charging contacts 200 and failure to make good contact with the charging contacts of the object to be charged, the fast-moving charging contact 200 is pulled by the stuck charging contact 200 through the linkage part 400. At this time, the stuck charging contact 200 is not only affected by the force of the reset part 300 but also pulled by the fast-moving charging contact 200, thereby breaking away from the stuck position, thereby achieving the effect of preventing the charging contact 200 from getting stuck.
[0048] In this embodiment, there are two charging contacts 200 corresponding to the charging slots 110, namely a positive contact and a negative contact. When the positive contact and the negative contact are in contact with the positive and negative charging contacts of the object to be charged at the same time and the charging contacts 200 of the charging pile are energized, the object to be charged is charged.
[0049] 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 charging requirements.
[0050] In this embodiment, the charging contact 200 includes a charging sheet 230 and a charging sheet bracket 240. The charging sheet 230 is detachably connected to the charging sheet bracket 240 and is located on a side away from the charging slot 110. The charging sheet bracket 240 is slidably connected to the charging slot 110. By separating the charging sheet 230 and the charging sheet bracket 240, the cost of replacing components of the charging pile is reduced.
[0051] According to one embodiment of the utility model, combined Figure 2 and Figure 3 As shown, the charging contact 200 is provided with a limiting space 210, and the two ends of the linkage member 400 can be movably connected in the limiting spaces 210 of different charging contacts 200. The limiting space 210 prevents the linkage member 400 and the charging contact 200 from getting stuck, and avoids the problem that the displacement difference between the charging contacts 200 due to the blocking is generated, and the linkage member 400 is stuck with the charging contact 200 and the displacement difference between the charging contacts 200 cannot be adjusted.
[0052] According to one embodiment of the utility model, combined Figure 2 and Figure 3 As shown, the charging contact 200 is provided with a connecting column 220, and a ring groove 221 is radially opened on the connecting column 220, and the ring groove 221 forms a limiting space 210; first connecting holes 410 are provided at both ends of the linkage member 400, and the first connecting hole 410 is sleeved on the connecting column 220 and can be movably connected in the ring groove 221.
[0053] In this embodiment, the first connecting hole 410 is sleeved on the bottom wall of the annular groove 221, and a gap is provided between the first connecting hole 410 and the bottom wall, so as to realize the radial position adjustment between the linkage member 400 and the charging contact 200 along the connecting column 220; the side wall of the annular groove 221 realizes the axial limitation of the first connecting hole 410 along the connecting column 220, so as to realize the axial position adjustment between the linkage member 400 and the charging contact 200 along the connecting column 220, and avoid the jamming between the charging contact 200 and the linkage member 400.
[0054] Of course, the movable connection form between the charging contact 200 and the linkage member 400 is not limited to the above-mentioned form. For example, the annular groove 221 can be set on the linkage member 400, and the first connection hole 410 can be set on the connection column 220 to achieve the limit and movable connection between the two. It can be understood that when the linkage member 400 is in sheet form, "the annular groove 221 is set on the linkage member 400" can be understood as a cross-sectional shape of an annular groove formed on the sheet-like linkage member 400, similar to the "I" shape. It can also be a spherical groove set on the charging contact 200, and a ball head with a slightly smaller diameter is correspondingly set on the linkage member 400, etc., to achieve the limit and movable connection between the charging contact 200 and the linkage member 400.
[0055] According to one embodiment of the utility model, combined Figure 3 As shown, the connecting column 220 includes a column body 222, and the column body 222 forms a first shaft segment 223 and a second shaft segment 224 in sequence along a set direction. The diameter of the first shaft segment 223 is greater than the diameter of the second shaft segment 224, and the end of the second shaft segment 224 away from the first shaft segment 223 is detachably connected to a cap body 225, and the first shaft segment 223, the second shaft segment 224 and the cap body 225 form an annular groove 221.
[0056] During installation, the staff first sleeves the first connection hole 410 on the second shaft segment 224, and then fixes the cap body 225 to the end of the second shaft segment 224 to form the annular groove 221 to limit the first connection hole 410. The provision of the cap body 225 effectively reduces the difficulty of installing the first connection hole 410 on the connection column 220, thereby reducing production costs.
[0057] Of course, the second shaft segment 224 may also be a part of the cap body 225 , and the corresponding second shaft segment 224 is detachably connected to the first shaft segment 223 to form the annular groove 221 .
[0058] According to one embodiment of the utility model, combined Figure 2As shown, the housing 100 further includes a limiting column 120 extending along a set direction, the limiting column 120 is located between adjacent charging contacts 200, and the linkage member 400 is slidably connected to the limiting column 120 along the set direction. The limiting column 120 ensures that the moving direction of the linkage member 400 is always the same as the set direction, thereby preventing the linkage member 400 from coming off the limiting column 120 and colliding with other components in the charging pile.
[0059] In one embodiment, in combination Figure 2 and Figure 4 As shown, the linkage member 400 is provided with a second connection hole 420, and the second connection hole 420 is sleeved on the limiting column 120. Of course, the second connection hole 420 can also be set on the limiting column 120, and the linkage member 400 passes through the second connection hole 420; a slide groove can also be set on the limiting column 120 along a set direction, and a slider and other structures can be set on the linkage member 400 corresponding to the slide groove to realize the sliding connection of the linkage member 400 on the limiting column 120.
[0060] In one embodiment, in combination Figure 1 As shown, the charging pile further includes a limit plate 500, which is connected to the end of the limit column 120 that is away from the housing 100, and is suitable for preventing the linkage member 400 from being separated from the limit column 120 along the set direction. The limit plate 500 ensures that the linkage member 400 does not exceed the length range of the limit column 120, and prevents the linkage member 400 from hitting the components outside the limit column 120; and by replacing the limit plates 500 with different thicknesses, the maximum movable distance of the linkage member 400 along the set direction can be adjusted to adapt to the layout of different internal components of the charging pile.
[0061] According to one embodiment of the utility model, combined Figure 4 As shown, the second connection hole 420 is a waist-shaped hole, and the long side of the waist-shaped hole extends along the distribution direction of the charging contacts 200. The waist-shaped hole can adapt to the inclination of the charging contacts 200 along the distribution direction, avoid the linkage member 400 and the limit column 120 from getting stuck, resulting in the charging contacts 200 being unable to form a linkage, and prevent the linkage member 400 and the limit column 120 from getting stuck, which will also hinder the movement of the charging contacts 200.
[0062] In this embodiment, the distribution direction of the charging contacts 200 is from top to bottom, so the extension direction of the long side of the waist-shaped hole is from top to bottom; of course, according to the distribution direction of the charging contacts 200 (such as left and right distribution), the extension direction of the long side of the waist-shaped hole can be adaptively adjusted to the left and right direction.
[0063] According to an embodiment of the present invention, the linkage member 400 is an elastic linkage member, which is suitable for generating elastic deformation when one of the charging contacts 200 is stuck.
[0064] The elastic deformation of the elastic linkage part increases with the displacement difference between the charging contacts 200. Compared with the linkage part 400 that cannot be elastically deformed, the deformation recovery force provided for overcoming the jamming increases with the displacement difference, thereby effectively improving the anti-jamming effect of the linkage part 400 on the charging contacts 200, avoiding the probability that one of the charging contacts 200 moves into place and the other side gets stuck, thereby ensuring the charging effect of the charging pile.
[0065] In this embodiment, the elastic linkage part is in the form of an integrated elastic sheet, which has low manufacturing cost and is easy to produce; of course, the elastic linkage part can also be in the form of a rigid part with elastic parts connected at both ends, such as a rigid plate with springs connected at both ends, and the other end of the spring is connected to the charging contact 200.
[0066] According to one embodiment of the utility model, combined Figure 2 As shown, the elastic linkage member is provided with a bending portion 430, and the opening of the bending portion 430 faces away from the set direction. The elastic linkage member with the bending portion 430 can provide a larger deformation amount than the straight plate type linkage member 400, effectively improving the maximum deformation recovery force of the elastic linkage member and improving the anti-jamming effect on the charging contact 200.
[0067] According to one embodiment of the utility model, combined Figure 1 As shown, at least two linkage members 400 are included, and the at least two linkage members 400 are distributed along the length direction of the charging contact 200 .
[0068] In this embodiment, for ease of description, the length direction in the accompanying drawings is taken as the left-right direction, and the distribution direction of the charging contacts 200 is taken as the up-down direction. When the object to be charged presses against the charging contacts 200, there may be a problem that the pressure is not along the set direction, resulting in a certain inclination angle of the charging contacts 200 in the left-right direction.
[0069] By means of the independently arranged left and right linkage parts 400, that is, the left and right blocking adjustments of the two charging contacts 200 do not interfere with each other, the left and right adaptive fitting of the charging contacts 200 to the object to be charged is achieved, thereby avoiding the charging contacts 200 from being stuck or stuck in the left and right directions, and ensuring the charging effect of the object to be charged.
[0070] Of course, it is understandable that the middle position of the charging contact 200 along the length direction is close to the center of gravity, so it is easier to contact with the charging slot 110 and cause jamming. Based on the length of the charging contact 200, the number and method of the linkage parts 400 can be adaptively adjusted to improve the anti-jamming effect, such as setting three contacts, two of which are located at the two ends of the length direction, and the other is located at the center of the charging contact 200 along the length direction.
[0071] 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.
[0072] According to the second aspect of the present invention, the robot system includes a robot body and a charging pile as in the above embodiment, wherein the charging pile is electrically connected to the robot body and is used to charge the robot body.
[0073] 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.
[0074] 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.
