[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] The following is a reference appendix. Figures 1 to 6 This invention describes a charging actuator, a charging device, and a charging system according to embodiments of the present invention.

[0041] like Figures 1 to 4 As shown, the charging actuator of this embodiment of the invention includes a driving device 1 and a mounting base 9. The driving device 1 includes a first translation component 11, a second translation component 12, and a third translation component 13. The second translation component 12 is mounted on the first translation component 11, and the third translation component 13 is mounted on the second translation component 12. The first translation component 11 drives the second translation component 12 to move along a first direction, and the second translation component 12 drives the third translation component 13 to move along a second direction. The mounting base 9 is used to mount the charging gun 2. The mounting base 9 is disposed on the third translation component 13, and the third translation component 13 drives the mounting base 9 to move along a third direction. Any two of the first direction, the second direction, and the third direction have a preset angle between them.

[0042] According to an embodiment of the present invention, the charging actuator can drive the second translation component 12 to move along the first direction, the second translation component 12 can drive the third translation component 13 to move along the second direction, and the third translation component 13 can drive the charging gun 2 to move along the third direction via the mounting base 9. There is a preset angle between any two of the first direction, the second direction and the third direction. Thus, the position of the charging gun 2 in three-dimensional space can be adjusted by the driving device 1 so that the charging gun 2 is aligned with the power receiving base 101 of the vehicle 10, thereby reducing the requirement for the accuracy of vehicle parking, making it more robust, adaptable to different vehicle models, and having a wider range of applications, which is conducive to large-scale promotion and application.

[0043] On the other hand, compared with the solution of "multi-axis serial robotic arm driving the charging gun 2 to move", the charging actuator of the embodiment of the present invention has a simple structural design and lower manufacturing cost.

[0044] In the examples of this invention, the mounting base can be a plate-like structure or a block-like structure, and this invention does not limit it.

[0045] Optionally, the preset included angle between any two of the first direction, the second direction, and the third direction is 90°. In other words, the first direction, the second direction, and the third direction are orthogonal to each other. This facilitates the planning of the movement paths of the first translation component 11, the second translation component 12, and the third translation component 13, and allows the mounting base 9 to be adjusted to the preset position by moving the first translation component 11, the second translation component 12, and the third translation component 13 by the shortest distance.

[0046] In an example of this invention, the first direction can be the X direction, such as the left-right direction of a vehicle. The second direction can be the Y direction, such as the front-back direction of a vehicle. The third direction can be the Z direction, such as the up-down direction of a vehicle.

[0047] Optionally, such as Figure 2 and Figure 3 As shown, the first translation component 11 includes a first base 111, a first motor 112, and a first transmission pair 113. The first transmission pair 113 is disposed on the first base 111 and connected to the second translation component 12. The first motor 112 is connected to the first transmission pair 113, and the first motor 112 can drive the second translation component 12 to move along a first direction through the first transmission pair 113. By adopting the above structural design, the first translation component 11 of this embodiment can adjust the position of the second translation component 12 along the first direction. Since the first translation component 11 is driven by a motor, the accuracy of the second translation component 12's movement along the first direction can be improved. Furthermore, the first translation component 11 has a simple structural design and low cost.

[0048] like Figure 2 and Figure 3 As shown, the driving device 1 also includes a guide assembly 14. The guide assembly 14 and the first translation assembly 11 are arranged at intervals along a second direction. The guide assembly 14 includes a first guide rail 141 and a first slider 142. The first slider 142 is disposed on the second translation assembly 12 and is slidably connected to the first guide rail 141 along a first direction. It can be understood that when the first motor 112 drives the second translation assembly 12 to move along the first direction through the first transmission pair 113, the second translation assembly 12 can slide with the first guide rail 141 through the first slider 142 to provide auxiliary support and guidance for the second translation assembly 12, which helps to improve the stability of the second translation assembly 12 during movement.

[0049] For example, the first transmission pair 113 is one of a lead screw and nut transmission pair, a gear and rack transmission pair, and a sprocket and chain transmission pair. This makes the transmission method of the first transmission pair 113 simple and reliable, and at a low cost.

[0050] In the example of the present invention, the first transmission pair 113 is a lead screw and nut transmission pair, which can ensure the accuracy of the position adjustment of the first translation component 11.

[0051] Optionally, such as Figure 2 and Figure 3 As shown, the second translation component 12 includes a second base 121, a second motor 122, and a second transmission pair 123. A first transmission pair 113 is connected to the second base 121, and the second transmission pair 123 is located on the second base 121 and connected to the third translation component 13. The second motor 122 is connected to the second transmission pair 123, and the second motor 122 can drive the third translation component 13 to move along a second direction via the second transmission pair 123. By adopting the above structural design, the second translation component 12 of this embodiment can adjust the position of the third translation component 13 along the second direction. Since the second translation component 12 is driven by a motor, the accuracy of the third translation component 13's movement along the first direction can be improved. Furthermore, the structural design of the second translation component 12 is simple and the cost is low.

[0052] For example, the second transmission pair 123 is one of a lead screw and nut transmission pair, a gear and rack transmission pair, and a sprocket and chain transmission pair. This makes the transmission method of the second transmission pair 123 simple and reliable, and at a low cost.

[0053] In the example of the present invention, the second transmission pair 123 is a lead screw and nut transmission pair, which can ensure the accuracy of the position adjustment of the second translation component 12.

[0054] Optionally, such as Figure 3 and Figure 4 As shown, the third translation component 13 includes a third motor 131, a gear (not shown), and a rigid chain 132. The third motor 131 is connected to the gear, the gear meshes with the rigid chain 132, and the rigid chain 132 is connected to the mounting base 9. The third motor 131 can drive the gear to rotate, and the gear can drive the rigid chain 132 to extend and retract in a third direction to adjust the position of the mounting base 9. Since the third translation component 13 moves the mounting base 9 by driving the rigid chain 132 with a motor, compared with the method of "motor driving a lead screw for transmission", the space occupied by the third translation component 13 can be reduced.

[0055] In addition, based on the characteristics of the rigid chain 132 itself, the rigid chain 132 has a certain degree of flexibility. When the rigid chain 132 is compressed or stretched under the action of external force, the size of the rigid chain 132 can change slightly in sync to ensure the reliability of the contact between the mounting seat 9 and the power receiving seat 101 of the vehicle.

[0056] Optionally, such as Figure 3 and Figure 4As shown, the drive device 1 also includes a rotating assembly 15. The third translation assembly 13 is connected to the second translation assembly 12 via the rotating assembly 15. The rotating assembly 15 can drive the third translation assembly 13 to rotate around a first axis, which is parallel to the third axis. It can be understood that the drive device 1 has three translational degrees of freedom and one rotational degree of freedom. That is, the drive device 1 can move the mounting base 9 in the XYZ directions via the first translation assembly 11, the second translation assembly 12, and the third translation assembly 13, and can rotate the mounting base 9 around the Z-axis via the rotating assembly 15, so that the mounting base 9 can be accurately aligned and engaged with the vehicle's power receiving base 101.

[0057] Therefore, the charging actuator of the embodiment of the present invention, by setting the rotating component 15, can further reduce the requirements for the accuracy of vehicle parking and has a wide range of applications.

[0058] Optionally, such as Figure 4 As shown, the rotating assembly 15 includes a fourth motor 151 and a rotating platform 152. The rotating platform 152 is rotatable relative to the second translation assembly 12 along a first axis. A third translation assembly 13 is disposed on the rotating platform 152. The fourth motor 151 is connected to the rotating platform 152 to drive the rotating platform 152 to rotate. By adopting the above-described structural design of the rotating assembly 15, the charging actuator of this embodiment of the invention can adjust the rotation angle of the third translation assembly 13 around the first axis. Since the rotating assembly 15 is driven by a motor, the rotational accuracy of the rotating platform 152 can be improved. Furthermore, the structural design of the rotating assembly 15 is simple and the cost is low.

[0059] Optionally, such as Figure 1 and Figure 3 As shown, the charging actuator also includes a shielding curtain 3, at least a portion of which is located on the outer periphery of the third translation component 13 and the mounting base 9. Under the shielding effect of the shielding curtain 3, the user's line of sight will not directly observe the internal structure of the third translation component 13 and the mounting base 9. This improves the overall appearance of the charging actuator and isolates the third translation component 13 and the mounting base 9 from direct human contact, thus enhancing safety during use.

[0060] For example, the blind curtain 3 can be a corrugated (accordion-shaped) retractable curtain.

[0061] In some embodiments, such as Figure 4As shown, the mounting base 9 also includes a floating device 4. The mounting base 9 is connected to the third translation component 13 through the floating device 4. When the mounting base 9 is compressed, the floating device 4 can deform. When the mounting base 9 is released from compression, the floating device 4 can drive the mounting base 9 to return to its initial position. When the mounting base 9 is engaged with the vehicle's power receiving base 101, the mounting base 9 will also move when the vehicle chassis shakes up and down. Since the floating device 4 can deform, it can adaptively compensate for the positional changes of the mounting base 9 to ensure the reliability of the contact between the mounting base 9 and the vehicle's power receiving base 101.

[0062] like Figure 4 As shown, the floating device 4 includes a first plate 41, a second plate 42, and an elastic element 43. The elastic element 43 is disposed between the first plate 41 and the second plate 42. The mounting base 9 is connected to the first plate 41, and the second plate 42 is connected to the third translation component 13. It can be understood that the elastic element 43 can be stretched or compressed in the vertical direction, thereby adaptively compensating for changes in the position of the mounting base 9. Furthermore, the floating device 4 has a simple structural design and is easy to manufacture.

[0063] like Figure 4 As shown, the elastic element 43 can be a cylindrical spring. There can be multiple elastic elements 43, which are arranged at intervals between the first plate 41 and the second plate 42.

[0064] like Figure 1 As shown, the charging actuator also includes a positive charging cable (not shown) and a negative charging cable (not shown). The positive and negative charging cables are respectively arranged on both sides of the mounting base 9 and electrically connected to it. For example, both the positive and negative charging cables are flexible copper busbar power lines (DC+, DC-). This allows the positive and negative charging cables to maintain high current carrying capacity while possessing good flexibility, enabling them to move within the effective operating range along with the mounting base 9.

[0065] For example, the charging gun 2 is electrically connected to a fuse (not shown), which can blow to protect the remaining electrical components when an overload occurs.

[0066] like Figure 4 and Figure 5 As shown, the charging gun 2 includes a charging body 21 and guide posts 22. The positive and negative terminals of the charging body 21 are connected to the positive charging cable and the negative charging cable, respectively. There can be two guide posts 22, which are arranged on both sides of the charging body 21. The guide posts 22 are used to provide guidance when the charging body 21 docks with the power receiving socket 101 of the vehicle, so as to improve the docking efficiency between the charging gun 2 and the power receiving socket 101.

[0067] The charging actuator also includes a take-up coil (not shown), which works in conjunction with the positive and negative charging cables to constrain their movement trajectories and prevent them from obstructing the positioning camera from taking pictures.

[0068] like Figure 1 As shown, the charging actuator also includes two insulating baffles 8, which correspond to the positive charging wire and the negative charging wire, respectively. It is understood that the positive and negative charging wires are positioned between the two insulating baffles 8, thereby preventing insulation failure caused by direct contact between the positive and negative charging wires and the outer casing 5.

[0069] like Figure 1 and Figure 5 As shown, another embodiment of the charging device of the present invention includes: a housing 5, a charging actuator, and a charging gun 2. The housing 5 has a receiving cavity 51. The charging actuator is the charging actuator of the present invention, and at least a portion of the charging actuator is disposed in the receiving cavity 51. The driving device 1 can drive the charging gun 2 to extend and retract into the receiving cavity 51. The charging gun 2 is disposed on the mounting base 9.

[0070] According to an embodiment of the present invention, the charging device can drive the second translation component 12 to move along the first direction, the second translation component 12 can drive the third translation component 13 to move along the second direction, and the third translation component 13 can drive the charging gun 2 to move along the third direction. There is a preset angle between any two of the first direction, the second direction, and the third direction. Thus, the position of the charging gun 2 in three-dimensional space can be adjusted by the driving device 1 so that the charging gun 2 is aligned with the charging receiver 101 of the vehicle, thereby reducing the requirement for the accuracy of vehicle parking. It has a wide range of applications and is conducive to large-scale promotion and application.

[0071] In addition, since the drive device 1 can drive the charging gun 2 to extend and retract into the receiving cavity 51, the outer shell 5 can shield and protect the charging actuator.

[0072] For example, the housing 5 can be disposed in a pit in the ground. When the charging actuator is not in use, the drive device 1 can drive the charging gun 2 to retract into the receiving cavity 51 to reduce the space occupied by the charging device.

[0073] Optionally, such as Figure 5As shown, the charging device also includes a protective cover 6, which is installed on the upper end of the housing 5. The protective cover 6 is movable between an open position and a closed position. In the closed position, the protective cover 6 seals the upper port of the receiving cavity 51. In the open position, the protective cover 6 opens the upper port of the receiving cavity 51, allowing the charging gun 2 to extend out of the receiving cavity 51. Since the protective cover 6 can seal the upper port of the receiving cavity 51 in the closed position, it can prevent personnel from falling into the receiving cavity 51 and prevent rainwater or dust from entering the receiving cavity 51, thereby improving the safety of the charging device during use.

[0074] Optionally, the charging device also includes a driver connected to the protective cover 6, which can drive the protective cover 6 to translate along an orthogonal third direction to open and close the receiving cavity 51. It is understood that the protective cover 6 can be automatically opened and closed by the driver, thereby facilitating user operation.

[0075] In addition, the driver drives the protective cover 6 to translate in a direction orthogonal to the third direction, that is, the driver drives the protective cover 6 to translate in a horizontal direction. Compared with the solution of "the protective cover 6 is opened by rotation", the space occupied by the charging equipment can be reduced and the vehicle chassis can be avoided from being scratched.

[0076] like Figure 5 As shown, the protective cover 6 includes a first cover 61 and a second cover 62. In the closed position, the first cover 61 and the second cover 62 are connected, and in the open position, the first cover 61 and the second cover 62 are spaced apart along a direction orthogonal to a third. Compared to the dialectic that "the protective cover 6 is a single cover", this improves the efficiency of opening and closing the protective cover 6.

[0077] For example, either the first cover 61 or the second cover 62 has a waterproof flange on its outer edge, which extends horizontally out of the outer side of the housing 5 and downwards to avoid the problem of water being introduced into the receiving cavity 51.

[0078] For example, a sealing strip can be provided at the splicing position of the first cover 61 and the second cover 62 to further improve the sealing effect of the protective cover 6.

[0079] Optionally, the drive includes a fifth motor (not shown) and a sixth motor (not shown), with the fifth motor connected to the first cover 61 and the sixth motor connected to the second cover 62. It is understood that the first cover 61 and the second cover 62 are driven by their respective motors to improve the ease of opening and closing, and the transmission method is simple and reliable.

[0080] Optionally, such as Figure 1 and Figure 2As shown, the charging device also includes a control module 7, which is located in the receiving cavity 51 and is electrically connected to the drive device 1, thereby improving the compactness of the component arrangement within the charging device.

[0081] Optionally, the charging device also includes a positioning camera (not shown), which is installed in the receiving cavity 51 and is used to take pictures and position the charging receiver 101 at the bottom of the vehicle. Thus, the drive unit 1 can move the charging gun 2 to the target position according to the positioning parameters of the positioning camera, so that the charging gun 2 can be smoothly inserted into the charging receiver 101 of the vehicle.

[0082] For example, the positioning camera is mounted on the base plate 52 of the housing 5, and the positioning camera is fixed relative to the housing 5, thereby ensuring the accuracy of the positioning camera's shooting. Accordingly, a supplementary light (not shown) can be provided on the base plate 52 of the housing 5 to make the image captured by the positioning camera clearer.

[0083] The charging system of an embodiment of the present invention includes: a charging device, a charging terminal 20, and a charging host 30. The charging device is the charging device of the present invention.
