An embodiment of the utility model provides a charging pile. The charging pile is used for supplying power to the robot. The charging pile comprises a power supply device 10, when the robot contacts and presses the power supply device 10, the power supply device 10 can adaptively deform according to the specific gesture of the charging electrode of the robot when pressing the power supply device 10, so as to adapt to the alignment error of the robot relative to the power supply device 10, and ensure that the power supply device 10 can keep stable contact with the charging electrode of the robot.

Referring to fig. 1, in one embodiment, the power supply device 10 includes a support 100, an electrode member 200, and an elastic structure 300. The electrode member 200 is used for being in contact with a charging electrode surface of the robot for charging, that is, supplying electric energy to the robot by means of contact. The elastic structure 300 is elastically connected between the support 100 and the electrode member 200, so that the electrode member 200 can elastically move relative to the support 100. The electrode member 200 is provided with a first guide portion 201, the holder 100 is provided with a second guide portion 110, and the first guide portion 201 cooperates with the second guide portion 110 to guide movement of the electrode member 200 in a direction approaching or separating from the holder 100 and to enable the electrode member 200 to rotate relative to the holder 100.

In the power supply device 10, the first guide portion 201 cooperates with the second guide portion 110 to guide the movement of the electrode member 200 toward and away from the bracket 100, and at the same time, to enable the electrode member 200 to rotate relative to the bracket 100. Furthermore, the elastic structure 300 also enables the pole element 200 to be elastically movable relative to the bracket 100. In this way, the electrode member 200 can move in a direction approaching the holder 100 and compress the elastic structure 300 when contacting the robot, and the electrode member 200 can be kept in close contact with the robot by the elastic structure 300. Meanwhile, since the electrode member 200 can also rotate relative to the bracket 100, when the robot and the power supply device 10 are in alignment deviation, the electrode member 200 can adaptively compress the elastic structure 300 to adapt to the alignment deviation of the robot, so that the electrode member 200 can be attached to the robot to achieve sufficient surface contact connection. Thus, the power supply device 10 is more stable when charging the robot.

For ease of understanding, the surface of pole piece 200 that is used to contact the charging electrode of the robot is referred to as contact surface 202 in each embodiment.

Referring to fig. 1 and 2, in one embodiment, the first guiding portion 201 includes a guiding hole 201a, and the second guiding portion 110 is disposed through the guiding hole 201a. Since the second guide portion 110 is disposed in the guide hole 201a in a clearance manner, the guide hole 201a can limit the second guide portion 110 to move only within a predetermined range. In this way, the electrode member 200 can move only within a preset range relative to the bracket 100 by providing the guide hole 201a, that is, the electrode member 200 adaptively and elastically moves within the preset range relative to the bracket 100, so as to adapt to the alignment error of the robot.

Of course, in some embodiments, the second guiding portion 110 may also be disposed on the electrode member 200, and the first guiding portion 201 is correspondingly disposed on the support 100, that is, the guiding hole 201a is disposed on the support 100, so that the electrode member 200 can also adaptively and elastically move only within a preset range relative to the support 100 through the cooperation of the guiding hole 201a and the second guiding portion 110. In each embodiment, the first guiding portion 201 is disposed on the electrode member 200, and the second guiding portion 110 is disposed on the bracket 100 for convenience of description. It should be understood that the same is true of the contrary, so that the descriptions of the embodiments are not repeated.

Referring to fig. 1 and 2, in one embodiment, the elastic structure 300 includes two elastic members 310, and each of the two portions of the electrode member 200 located at two sides of the first guiding portion 201 is connected to one elastic member 310, and the electrode member 200 can deflect in a direction of compressing either elastic member 310. That is, the two elastic members 310 are respectively connected to both sides of the electrode member 200 where the guide holes 201a are formed. Since the guide hole 201a and the first guide portion 201 cooperate with each other to guide the movement of the electrode member 200, it is arranged that the elastic member 310 provides elastic force to the electrode member 200 regardless of which side of the first guide portion 201 the electrode member 200 rotates. Therefore, no matter which side of the robot has an alignment error, the electrode piece 200 can be adaptively deformed and keep close surface contact with the charging electrode of the robot.

Specifically, referring to fig. 2, when the robot contacts the electrode member 200 and there is a yaw angle error between the robot and the electrode member 200, a partial region on the charging electrode will first contact a partial region on the contact surface 202 of the electrode member 200 and press the region downward, so that the electrode member 200 is correspondingly rotated by a certain angle. The elastic member 310 corresponding to the pressed region is also compressed, and the electrode member 200 is pushed against the charging electrode in the opposite direction to make full contact and fit. When the contact surface 202 is fully contacted with the charging electrode, the elastic members 310 positioned at two sides of the electrode member 200 are compressed, so that the contact surface 202 can be adaptively deflected to an angle matched with the charging electrode through the elastic structure 300, the contact surface 202 is fully contacted with the charging electrode, and the safety and stability of the charging of the robot are ensured. Meanwhile, since the self-adapting process of the contact surface 202 compresses the elastic structure 300, the contact surface 202 will maintain close contact with the charging electrode under the elastic restoring action of the elastic structure 300, i.e. there is a pretightening force between the contact surface 202 and the charging electrode. The electrode member 200 is turned at a certain angle with reference to the direction K in fig. 3.

Referring to fig. 2, in one embodiment, the guide hole 201a extends in a reference direction. In the reference direction, the size of the guide hole 201a is larger than that of the second guide 110. That is, the second guide 110 can move at least a certain distance in the reference direction within the guide hole 201a. Correspondingly, the pole element 200 can be displaced at least by a certain distance in the reference direction relative to the carrier 100. Thus, the electrode member 200 has a certain moving space to compress the elastic structure 300, so as to ensure the self-adaptive alignment of the electrode member 200. The above reference directions are referred to in the X-axis direction in fig. 2.

Referring to fig. 3, the guide hole 201a extends along the reference direction, and the second guide portion 110 is further capable of deflecting in the guide hole 201a around a direction perpendicular to the reference direction. Specifically, referring to fig. 2, a direction perpendicular to the reference direction is taken as a Y-axis. Since the guide hole 201a extends in the reference direction and the size of the guide hole 201a is larger than that of the second guide portion 110 in the reference direction, the second guide portion 110 can also deflect around the Y-axis within the guide hole 201a. In connection with fig. 1, the pole element 200 is capable of pitch deflection relative to the support 100.

Specifically, when a pitch error occurs when the robot is aligned with the charging post, the contact of the charging electrode with the contact surface of the electrode member 200 can cause the electrode member 200 to pitch and deflect accordingly, so that the electrode member 200 can be electrically connected with the charging electrode holding surface of the robot in contact.

Referring to fig. 3 and 4, in one embodiment, the support 100 further includes a plurality of baffle plates 120 extending in a direction approaching the electrode member 200. The electrode member 200 is sandwiched between the adjacent blocking pieces 120, and two ends of the second guiding portion 110 are respectively connected to the blocking pieces 120 located at two sides of the electrode member 200. It can be appreciated that, since the electrode member 200 is sandwiched between the adjacent baffle plates 120, and the two ends of the second guiding portion 110 are respectively connected to the baffle plates 120 located at two sides of the electrode member 200, the electrode member 200 cannot be separated from any end of the second guiding portion 110 by the second guiding portion 110 cooperating with the baffle plates 120. The position of the electrode member 200 is fixed to the holder 100 within a certain range.

With continued reference to fig. 1 and 4, in one embodiment, the shortest distance between the tabs 120 on both sides of the electrode 200 is greater than the dimension of the electrode 200 between the two tabs 120. That is, in the Z-axis direction shown in fig. 1 and 4, there is a space between at least one side of the electrode member 200 and the barrier sheet 120. Thus, the electrode member 200 is ensured to have a space for rotation when rotating around the Y axis; meanwhile, the separation of the electrode member 200 from the holder 100 can be prevented by providing the blocking piece 120.

It is understood that the shortest distance between the baffle plates 120 on both sides of the electrode assembly 200 may be specifically designed according to the expected pitch angle deviation range during alignment, and will not be described herein.

In some embodiments, the guiding holes 201a may not penetrate through the electrode member 200, and guiding holes 201a may be formed on two opposite sides of the electrode member 200, and the positions of the guiding holes 201a located on two opposite sides of the electrode member 200 correspond to each other, where the guiding holes 201a are blind holes. Correspondingly, the baffle plates 120 on two sides of the displacement electrode member 200 are respectively connected with a section of second guide part 110, and the two sections of second guide parts 110 are respectively penetrated in the guide holes 201a on two sides corresponding to the gaps so as to limit the electrode member 200. The second guide portions 110 are correspondingly matched with the guide holes 201a one by one, and the movement of the electrode member 200 can be guided and limited.

With continued reference to fig. 2 in combination with fig. 3, in one embodiment, the guide hole 201a has a dimension that is greater than the dimension of the second guide 110 in a direction perpendicular to the reference direction. That is, in the Y-axis direction, a gap exists between at least one side of the second guide portion 110 and the wall of the guide hole 201a. In this way, the second guide 110 can be deflected not only about the Y axis but also about the X axis within the guide hole 201a, and the second guide 110 can be deflected also about the Y axis within the guide hole 201a. That is, the electrode member 200 can also rotate about the X-axis relative to the holder 100. Thus, the electrode assembly 200 has more degrees of freedom to accommodate different alignment deviations of the robot.

It should be appreciated that the second guide 110 generally does not require movement in a direction perpendicular to the reference direction relative to the reference direction. Therefore, in the direction perpendicular to the reference direction, the size of the guide hole 201a is slightly larger than that of the second guide portion 110 so that the second guide portion 110 has a space to rotate about the X axis. Of course, a larger gap between the second guide portion 110 and the guide hole 201a may be provided according to actual requirements.

Referring to fig. 1, in one embodiment, an electrode assembly 200 includes a positive electrode sheet 210 and a negative electrode sheet 220. The support 100 is provided with two second guide parts 110, and the two second guide parts 110 are respectively matched with a first guide part 201 arranged on the positive plate 210 and a first guide part 201 arranged on the negative plate 220. In this way, the positive electrode tab 210 and the negative electrode tab 220 can be limited by the first guide portion 201 and the second guide portion 110 which are correspondingly matched, so that both the positive electrode tab 210 and the negative electrode tab 220 only move within a desired range relative to the bracket 100.

It should be noted that, the positive electrode sheet 210 and the negative electrode sheet 220 are connected to the bracket 100 through different first guide portions 201 and different guide holes 201a, that is, the movement of the positive electrode sheet 210 and the negative electrode sheet 220 under the driving action of the robot charging electrode is relatively independent. By the arrangement, the mutual interference between the positive plate 210 and the negative plate 220 can be avoided, so that the positive plate 210 and the negative plate 220 are guaranteed to be fully adapted to the alignment error of the charging electrode, and are kept in full surface contact with the charging electrode.

Referring to fig. 1, in one embodiment, the power supply device 10 includes a plurality of elastic structures 300. The part of elastic structure 300 is elastically connected between the positive plate 210 and the bracket 100, so that the positive plate 210 can elastically move relative to the bracket 100, and in this way, the positive plate 210 can adapt to the posture of the charging electrode in cooperation with the guiding action of the first guiding part 201 and the second guiding part 110, and the positive plate 210 is ensured to be in full surface contact with the charging electrode. The other part of elastic structure 300 is elastically connected between the negative electrode plate 220 and the bracket 100, so that the negative electrode plate 220 can elastically move relative to the bracket 100, and the negative electrode plate 220 can adapt to the posture of the charging electrode by matching with the guiding action of the first guiding part 201 and the second guiding part 110, so as to ensure that the negative electrode plate 220 is fully contacted with the charging electrode.

Regarding the adaptive deflection of the electrode assembly 200, the positive electrode sheet 210 is taken as an example, and it should be understood that the negative electrode sheet 220 is the same, and thus will not be described again.

Referring to fig. 1, the positive plate 210 can move along the X-axis to compress the elastic structure 300 under the contact action of the charging electrode of the robot. When there is a left-right swing angle error of the charging electrode, the positive plate 210 moves along the X axis and deflects along the Z axis, so that the elastic members 310 positioned at both sides of the positive plate 210 have different compression amounts. Thus, the positive electrode sheet 210 adapts to the left-right swing angle error of the charging electrode. The K direction shown in fig. 2 is the direction of rotation about the Z axis.

When the pitch error exists in the charging electrode, the positive plate 210 can deflect around the Y axis, so that the positive plate 210 can adapt to the pitch error of the charging electrode.

The positive electrode tab 210 can also deflect along the X-axis to accommodate other alignment errors of the charge electrode.

That is, the adaptive deformation of the positive electrode tab 210 includes rotation about the X-axis, rotation about the Y-axis, rotation about the Z-axis, and movement along the X-axis. Of course, the dimensions of the guide hole 201a and the second guide portion 110 may be adjusted specifically, so that the positive plate 210 has other adaptive manners, which are not described herein.

It should be noted that, in the embodiments, the deformation of the electrode assembly 200 is used to adapt to and compensate for the deviation of the robot in alignment, and since an alignment module is usually disposed between the robot and the charging pile, the deviation of the alignment between the charging electrode and the electrode assembly 200 is usually not large. In other words, the adaptive deformation requirement of the electrode assembly 200 is not generally large, and the amount of misalignment between the electrode assembly 200 and the charging electrode due to the adaptive deformation of the power supply device 10 is not large. It will be appreciated that since the power supply device 10 is capable of maintaining surface contact with the charging electrode by adaptive deformation, the small amount of misalignment described above does not affect the actual charging process in the case of surface contact therebetween.

Referring to fig. 1 to 4, in one embodiment, the second guiding portion 110 may have a cylindrical shape, that is, the second guiding portion 110 has a rounded outer surface, so that the second guiding portion 110 can move in the guiding groove more flexibly.

In one embodiment, the second guide 110 may also be integrally provided with the bracket 100, i.e., the second guide 110 may be integrally provided with the flap 120.

Referring to fig. 1 and 2, in one embodiment, the electrode member 200 is provided with a limiting post 203 protruding toward the support 100. One end of the elastic piece 310 is sleeved on the limiting post 203, and the other end of the elastic piece 310 is connected with the bracket 100. In this way, the limiting posts 203 can limit the action of the elastic member 310, so as to avoid the elastic member 310 from being separated from the support 100 and the electrode member 200. The elastic member 310 may be a compression spring, and the elastic member 310 elastically pushes the electrode member 200 in a direction away from the support 100.

The number of the limiting posts 203 is two, and the two limiting posts 203 are arranged on two sides of the first guide part 201. One end of each of the two elastic members 310 is sleeved in the corresponding one of the two limiting posts 203, and the other ends of the two elastic members 310 are connected with the bracket 100.

Referring to fig. 2, in one embodiment, a part of the structure of the elastic member 310 is sleeved on the limiting post 203, and another part of the structure of the elastic member 310 is hollowed out. For the part of the elastic piece 310 sleeved on the limiting post 203, the elastic piece 310 and the limiting post 203 are mutually sleeved and matched to limit the elastic piece 310. For the hollowed-out portion of the elastic member 310, it is more easily deformed in various directions to be suitable for the deflection movement of the electrode member 200. It can be appreciated that the portion of the elastic member 310 sleeved on the limiting post 203 is relatively difficult to deform and deflect due to the support of the limiting post 203. In this embodiment, the elastic member 310 is provided with a hollow hole, so that the elastic member 310 can avoid affecting the deflection movement of the electrode member 200. It will be appreciated that, in the hollow portion of the elastic member 310, no limit post 203 is provided, and no other structure is provided, so as to ensure that the elastic member 310 can adapt to the deflection of the electrode member 200.

Of course, in some embodiments, the elastic member 310 may be integrally sleeved on the limiting post 203. At this time, the limit posts 203 may be provided with two or more sections having different radial dimensions, and at least one section of the limit posts 203 has a radial dimension substantially smaller than that of the elastic member 310 to facilitate the deflection of the electrode member 200.

It can be understood that the positive plate 210 and the negative plate 220 are respectively provided with two limiting posts 203, and the two limiting posts 203 on the positive plate 210 are respectively positioned at two sides of the region of the positive plate 210 opposite to the guide hole 201 a; similarly, the two limiting posts 203 on the negative plate 220 are respectively located at two sides of the region of the negative plate 220 opposite to the guide hole 201a. The number of the elastic pieces 310 may be 4, and one ends of the 4 elastic pieces 310 are respectively sleeved on the limit posts 203 on the positive plate 210 and the negative plate 220 correspondingly; the other ends of the 4 elastic members 310 are connected to the bracket 100.

Referring to fig. 1 and fig. 4, in one embodiment, the bracket 100 is provided with a limiting slot 130, one end of the elastic member 310 is sleeved on the limiting post 203, and the other end of the elastic member 310 is disposed through the limiting slot 130. In this way, the elastic member 310 can be prevented from being separated from the bracket 100 and the electrode member 200 by matching the limiting groove 130 with the limiting post 203, so as to ensure the self-adapting capability of the power supply device 10.

In some embodiments, the elastic structure 300 includes a spring, that is, the electrode member 200 may be elastically connected to the support 100 through the spring. Specifically, the spring plate includes a base plate (not shown, the same applies hereinafter) and two support arms (not shown, the same applies hereinafter) connected to the base plate. The base plate is connected to the bracket 100, and both support arms have elasticity. The electrode member 200 is supported by the two support arms at the positions on both sides of the first guide portion 201, and the electrode member 200 can deflect in a direction of bending either support arm. Because of the elasticity of the support arms, when the pole piece 200 is deflected in a direction of bending either support arm, the support arm can elastically push the pole piece 200 in a direction away from the bracket 100. Thus, the pole element 200 can also be adaptively moved by the two elastic support arms.
