Description

Technical Field

[0001] The present invention relates to the field of rail-mounted robot charging, and in particular to a charging docking device, a charging base station and a charging host for docking a rail-mounted robot with a charging base station. Background Art

[0002] With the popularity of new energy vehicles, the construction of charging infrastructure has become an important part of promoting the development of green transportation in various countries. However, due to the limited domestic parking space resources, the charging demand of new energy vehicles still depends on the widespread deployment of public charging piles. However, the existing fixed charging pile form and parking space status have reduced the utilization rate of a single charging pile, resulting in a decrease in resource utilization.

[0003] There are some types of rail-mounted charging robots on the market that attempt to optimize the charging process by changing the layout and operation mode of the charging piles. The existing rail-mounted mobile robot system usually includes a track, a mobile robot, a charging host, and a charging base station. In order to achieve the purpose of flexible charging, the rail-mounted charging robot needs to carry the charging host and dock with the fixed charging base station. However, the high load of the charging host and the positioning error of the mobile robot will cause the docking error between the charging host and the charging base station to be too large, which will lead to the failure of the charging host's pile placement task. Among them, the docking error refers to the centering size deviation relative to the theoretical plug-in and pull-out position when the connector (such as a plug assembly and a socket assembly, or a dynamic connector and a static connector) performs plug-in and pull-out actions during the docking process between the charging host and the base station. The Chinese patent application with publication number CN118323763A discloses a rail-mounted charging robot, which adopts a two-level telescopic mechanism to reduce the docking error, thereby realizing the charging host's pile placement task. However, the docking error is still unavoidable, so the docking interface between the host and the base station still has a certain risk of damage.

DETAILED DESCRIPTION

[0022] The exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative configuration of the components, digital representations and numerical values ​​described in these embodiments does not limit the scope of the present invention. For simplicity, the same structural parts or steps are used with the same marks or numbers, and their description is omitted.

[0023] In the following embodiments, a charging host that can be mounted on a rail-mounted robot is used as an example of a charging device, and a charging base station is used as an example of a power supply device. Obviously, the charging device can also be other charging devices such as a rail-mounted robot, and the power supply device can also be a power supply device such as a distribution box that can provide power.

[0024] like Figure 1A and Figure 1BAs shown, the rail-mounted charging system 1 includes a travel rail 50 arranged above the parking space, and a plurality of charging base stations 30 are arranged along the travel rail 50 corresponding to the position of the parking space, and a distribution box 40 is arranged on the charging base station 30. The rail-mounted robot 10 can travel along the travel rail 50, and the rail-mounted robot 10 can mount the charging host 20 in a loadable and unloadable manner, and can carry the charging host along the travel rail 50. When charging is to be performed, the rail-mounted charging robot 10 carries the charging host 20 and runs to a certain charging base station 30, and the rail-mounted charging robot 10 pushes the charging host 20 to the side of the charging base station 30, and the charging interface (such as the plug assembly 210) on the charging host 20 is docked with the charging interface (charging docking device, such as the socket assembly) on the charging base station to form an electrical connection. Among them, after the charging base station 30 is successfully docked with the charging host 20, the charging base station 30 can provide AC power to the charging host 20, and the charging host 20 can also provide DC power to the charging base station 30.

[0025] The following reference FIG. 2A to FIG. 2C , Figure 3A and Figure 3B as well as FIG. 4A to FIG. 4E , the structure of the charging base station side charging docking device (socket assembly) for docking with the charging host side charging docking device (plug assembly) mounted on the rail-mounted robot according to the present invention is described.

[0026] [Structure of the charging docking device at the charging base station] For ease of description, the following describes the posture of the charging docking device in the installed state. The front side (or front side, front side) refers to the side (or side) facing the charging device (or the plug assembly on the charging device side) during the docking process in the installed state, and the back side (or back side, rear side) refers to the side (or side) facing away from the charging device (or the plug assembly on the charging device side) during the docking operation in the installed state.

[0027] The following uses the socket assembly as an example of a charging docking device on the charging base station side to illustrate the structure of the charging docking device on the charging base station side (also referred to as a static charging docking device) according to the present invention. Figure 2A and Figure 2B as well as Figure 3A and Figure 3B The charging docking device (socket assembly) 400 for a charging base station includes: a socket 410, a socket mounting plate 420 and a floating plate 430. The socket mounting plate 420 is in the shape of a box with an open back. In this embodiment, the socket mounting plate 420 is in the shape of a rectangular box, but the present invention is obviously not limited thereto, and may also be in other shapes, such as a box with a circular, prismatic, or elliptical cross section.

[0028] The socket 410 is fixed on the floating plate 430. The socket 410 may be an electrical socket. As an option, it may be made separately from the floating plate 430 and fixed to the floating plate 430 by a fixing mechanism, or it may be made integrally with the floating plate 430. As an example, Figure 2A and 3A As shown, a rectangular opening matching the bottom shape of the socket 410 is provided at the center of the floating plate 430 , and the socket 410 can be fixed on the floating plate 430 by being embedded in the rectangular opening.

[0029] An opening area 422 is provided at the center of a main board 421 of the socket mounting plate 420, which serves as the front face of the flat box (the face that interfaces with the charging host in the installed state). The floating plate 430 is assembled in a suspended manner inside the socket mounting plate 420 so that the socket 410 is exposed from the opening area 422, so that the floating plate 430 and the socket 410 can float within the range of the opening area 422 of the main board 421.

[0030] Among them, as a preferred method, Figure 2A As shown, the opening area 422 of the mainboard 421 is a hexagon. Obviously, the present invention is not limited to this. The shape of the opening area 422 can also be a rectangle, an ellipse, a rounded corner or an obtuse rectangle, etc., which matches the shape of the docking component of the socket 410 so that the docking component of the socket 410 can be exposed from the opening area 422 and have a certain amount of movement space.

[0031] In addition, the charging docking device 400 further includes a floating baffle 430, and a floating baffle 450 is arranged on the back side (rear side) of the floating plate 430. As a suspension mechanism of the floating plate 430, for example, a tension spring 440 can be used. The tension spring 440 can be connected between the floating baffle 450 and the floating plate 430, or between the floating plate 430 and the socket mounting plate 420. As a preferred example, Figure 2A , Figure 4B , 4D As shown in FIG. 6D , one end of each tension spring 440 is connected to the periphery of the rectangular opening of the floating plate 430 , and the other end of each tension spring 440 may be connected to the edge of the floating baffle 450 .

[0032] As a preferred embodiment, a floating baffle opening 454 may be provided at the center of the floating baffle 450, and the floating plate 430 and the socket 410 may float within the range of the floating baffle opening 454. The shape of the floating baffle opening 454 may be, for example, Figure 2A The other end of each tension spring 440 can be connected to the periphery of the rectangular opening of the floating baffle 450. In addition, the floating baffle opening 454 facilitates the wiring outlet of the socket 410 to connect the wiring harness behind the socket.

[0033] As an alternative, one end of each tension spring 440 may be connected to the peripheral edge of the rectangular opening of the floating plate 430, and the other end of each tension spring 440 may be connected to the periphery of the rectangular opening area 422 of the main board 421. Through the elastic force of the tension spring 440, the two connected (for example, the floating baffle 450 and the floating plate 430, or the floating plate 430 and the socket mounting plate 420) can be parallel to the board surface of the main board 421 (such as Figure 5B Relative floating in the plane direction formed by the X-axis and the Y-axis shown in FIG.

[0034] As an example, the number of the tension springs 440 may be 4, but the number is obviously not limited thereto, and may also be 2, 3, 6, 8, etc.

[0035] In addition, if Figure 2A and 3A As shown, when the tension spring 440 is connected between the floating plate 430 and the floating baffle 450, the following structure can be adopted. Figure 2A As shown, four tension spring first mounting columns 431 are provided in groups of two at the positions on the left and right sides of the opening. The tension spring first mounting columns 431 can be provided in the form of step bolts. Correspondingly, threaded holes are provided at the corresponding positions of the floating plate 430 where the tension spring first mounting columns 431 are to be installed, as tension spring first mounting holes 432, so that the step bolts 431 are installed on the threaded holes 432, so that the tension spring first mounting columns 431 are connected to the tension spring first mounting holes 432. As an alternative, the tension spring first mounting columns 431 can also be integrally formed on the floating plate 430, in which case it is not necessary to provide tension spring first mounting holes.

[0036] Correspondingly, four second installation columns 451 of the tension spring are arranged on the floating baffle 450, and the distance between the second installation columns 451 of the tension spring on the floating baffle 450 and the first installation columns 431 of the tension spring on the floating plate 430 is greater than the natural length of the tension spring 440. The second installation columns 451 of the tension spring are connected to the second installation holes 452 of the tension spring. The structures of the second installation columns of the tension spring are similar to those of the first installation columns of the tension spring. As an optional method, the first installation columns of the tension spring and the second installation columns of the tension spring can be bolted or riveted.

[0037] By assembling the socket 410 in the opening area 422 of the socket mounting plate 420 and elastically suspending the floating plate 430 on the inner side of the socket mounting plate 420, the socket 410 of the socket assembly 400 can move within the range of the opening area 422 during docking with the plug 213 of the plug assembly 210 (plug 213 is inserted into the socket 410), and can be reset by the elastic force of the tension spring 440 when the docking is released (plug 213 is pulled out of the socket 410). In other words, the plug assembly 210 ( Figure 5A and Figure 5B After the socket 410 and the floating plate 430 of the socket assembly 400 are unplugged, they automatically return to the center (center) relative to the opening area 422 of the socket mounting plate 420, thereby ensuring that the next plug-in connection (docking operation) is normal.

[0038] As a preferred method, Figure 2C As shown, the upper and lower ends of the floating plate 430 extend downward and downward in the vertical direction respectively to overlap with the upper and lower end portions of the floating baffle 450, so that when the charging host 20 is pushed toward the charging docking device 400 to perform the docking operation between the charging docking device (socket assembly) 400 and the plug assembly 210 on the charging host 20 (as shown in 5A), the stopper 435 cooperates with the floating baffle 450 on the back side, and plays a role of floating support for the floating plate 430 or the socket 410 in the direction perpendicular to the board surface of the mainboard 421 (the direction in which the charging host 20 is pushed toward the charging docking device 400).

[0039] In addition, as a further preferred embodiment, the floating plate 430 can be assembled in a manner that it can be elastically extended and retracted in a direction perpendicular to the surface of the main plate 421. Figure 3A as well as FIG. 4A to FIG. 4E As shown, the charging docking device (socket assembly) 400 further includes: a compression spring 460 fixed to the back side of the floating baffle 450. For example, the compression spring 460 can be fixed to the back side of the floating baffle 450 with its axis perpendicular to the floating baffle 450, and the other end of the compression spring 460 can be fixed to the front side of the charging host. As a preferred method, Figure 2A , Figure 3A as well as Figure 5A As shown, the socket assembly 400 of the present invention further includes: a rear baffle 470 arranged on the back side of the floating baffle 450. The compression spring 460 is fixed at both ends to the floating baffle 450 and the rear baffle 470 in a posture where the axis is perpendicular to the floating baffle 450, so as to realize the floating baffle 450 relative to the rear baffle 470 in a direction perpendicular to the plate surface of the rear baffle 470 (along the direction of the rear baffle 470) by its telescopic elastic force. Figure 5B Relative floating of the Z axis.

[0040] Specifically, four rear baffle mounting holes 471 are provided on the rear baffle 470, and the rear baffle 470 is fixedly connected to the socket mounting plate 420 by, for example, screws 474. Figure 3B As shown, four compression spring second mounting posts 472 are provided on the rear baffle 470 for connecting with the compression spring 460. Correspondingly, four compression spring first mounting posts 453 are provided on the floating baffle 450 for connecting with one end of the compression spring 460. As a preferred option, the compression spring first mounting posts or the compression spring second mounting posts can be bolted or riveted. Preferably, a rear baffle opening 473 (such as Figure 2A and 2B As shown), the floating plate 430 and the socket 410 can float within the range of the rear baffle opening 473. In addition, the rear baffle opening 473 facilitates the wiring outlet of the socket 410 to connect the wiring harness behind the socket.

[0041] As an example, Figure 3A and 4D As shown, the number of the compression springs 460 is 4. Obviously, the present invention is not limited thereto, and the number of the compression springs 460 may also be 2, 6, 8, etc., depending on the shape of the installation box.

[0042] As a further preferred embodiment, at the position of the floating baffle 450 corresponding to the outer side (left and right sides) of the stopper 435 of the floating plate 430, a limit portion 455 is provided in a manner of being spaced a certain distance from the outer edge of the stopper 435. The distance is greater than the floating range, and the floating range is set according to the deviation amount when the charging docking device on the charging host side docks with the charging docking device on the charging base station side. As a preferred example, Figure 2C As shown, the limiting portion 455 may be in the form of a step extending forward from the front side of the floating baffle 450 (the side sides of the two pairs of floating plates 430 ).

[0043] In addition, the height of the limiting portion (step) 455 is greater than the thickness of the blocking portion 435 of the floating plate 430, so that in a natural state of not docking (the socket assembly 400 and the plug assembly 210 are not plugged together), the floating baffle 450 is pressed against the socket mounting plate 420 by the compression spring 460, and the inner end surface of the step 455 contacts the floating plate 430, so that the floating plate 430 can not only move in the left and right directions within the range defined by the limiting portion 455, but also the floating plate 430 and the blocking portion 435 can float back and forth in the space between the limiting portion 455 of the floating baffle 450 and the socket mounting plate 420.

[0044] As a preferred example, the shape of the stopper 435 can be as follows: Figure 2AThe rectangles shown are four in number, but the present invention is obviously not limited thereto, and their shapes may be, for example, semicircular or semi-elliptical, with straight sides located at the left and right ends of the floating plate 430 to face the stopper 455 of the floating baffle 450. The number of the stopper 435 may be, for example, two, one at the upper end and one at the lower end of the floating plate 430, respectively.

[0045] By setting the limiting part 455 and the stopper part 435, the moving range of the socket 410 or the floating plate 430 in the direction parallel to the board surface of the main board 421 can be limited, providing a certain redundant space for the alignment of the charging device during the docking process. In addition, with the reset elastic force provided by the tension spring 440, the docking posture of the charging device can be corrected, so that the plug assembly 210 of the docking charging device is facing the charging docking device (socket assembly 400) on the charging base station side, thereby improving the operability, accuracy and reliability of the charging docking.

[0046] As a further preferred embodiment, a guide post 434 protruding forward in a direction perpendicular to the surface of the main board 421 is provided on the floating board 430. As a preferred embodiment, the guide post 434 can be arranged around the socket 410, for example, on the left and right sides of the socket 410. In addition, a guide hole 433 is opened along the axis of the guide post 434. Figure 3A As shown, two guide posts 434 and two guide holes 433 are provided, and the guide holes 433 cooperate with the guide posts 434 to realize the guiding and positioning function. The guiding and positioning function will be further described later in conjunction with the structure of the plug assembly 210 on the charging device 20 side and the docking process.

[0047] In addition, wings are extended to the left and right sides at the bottom of the left and right side walls of the socket mounting plate 420 in a direction parallel to the surface of the main board 421, and a first mounting hole 423 of the mounting plate is provided on the wing for fixing to the charging base station 30 or the distribution box 40, and a second mounting hole 424 of the mounting plate extending to the back side (rear side) is provided on the inner side of the socket mounting plate for fixing to the rear baffle.

[0048] Therefore, the charging docking device of the present invention can automatically and passively straighten the charging host with positioning deviation by assembling the floating plate in a hanging manner, thereby avoiding damage to the docking interface caused by docking deviation caused by software positioning error and structural installation error.

[0049] like Figure 3B As shown in FIG. 1 , as a preferred embodiment, a thin pin and a thick pin are provided on the socket 410, wherein the thin pin is connected to the signal line and is arranged in the center of the socket, while the thick pin is connected to the power supply line and is arranged on the periphery of the thin pin. Preferably, the thick pin can be arranged on the left and right sides of the thin pin (such as Figure 2BAs shown), the thick pins may be arranged on the upper and lower sides of the thin pins, or the thick pins may be arranged to surround the periphery of the thin pins.

[0050] In addition, the thick pin of the socket 410 may include at least one of an AC pin and a DC pin. As a preferred mode, both AC pins and DC pins are included so that the charging device having the charging docking device of the present invention can simultaneously complete the functions of bidirectional power supply and signal transmission. For example, the charging base station can supply 380V power to the charging host via the AC pin, and the charging host can supply DC power to the charging base station via the DC pin.

[0051] By providing thin pins for connecting signal lines and thick pins for connecting power supply lines, the charging docking device according to the present invention can simultaneously supply 380V power to the charging host from the base station and DC power to the charging base station from the charging host, and can also simultaneously interact various signals of the charging gun itself with the charging host (such as temperature, vehicle BMS signals).

[0052] In an embodiment of the present invention, Figure 3B As shown, the number of thin pins is 24, using 4 6 array, and the thick pins are divided into 2 groups, each with 4 and 2 Obviously, the above structure is only an example, and the present invention is not limited thereto. According to different configurations of the power supply circuit and signal circuit of the rail-hanging robot or the charging host, corresponding configurations can be adopted for the number and arrangement of the thin pins and the thick pins.

[0053] In addition, if Figure 1A As shown, the charging docking device 400 according to the present invention can be installed on the charging base station 30 or on the distribution box 40 fixed on the charging base station 30 on the side opposite to the charging host 20. A plug assembly 210 is installed on the side of the charging host 20 opposite to the charging base station 30.

[0054] The following describes the process of docking the charging docking device (socket assembly) 400 on the charging base station side with the charging docking device (plug assembly) 210 on the charging host side in conjunction with the structure of the plug assembly 210 .

[0055] In summary, the charging docking device for a charging base station of the present invention has a simple structure and high docking accuracy and reliability. In addition, the charging docking device for a charging base station of the present invention can float within a certain range in a plane perpendicular to the docking movement. If the robot positioning is deviated, its adaptability can be used to automatically correct the position deviation, thereby improving the docking success rate and extending the service life of the docking interface.

[0056] [Structure of the charging docking device on the charging host side] The following uses the plug-in assembly as an example of a charging docking device on the charging host side. Figure 5A and Figure 5B , FIG. 6A to FIG. 6D as well as 7A to 7C , the structure of the charging host side charging docking device (also called dynamic charging docking device) according to the present invention is described.

[0057] For ease of description, the following description is based on the posture of the charging host side facing the charging docking device in the installed state. The front side (or front side) refers to the side (or side) facing the charging base station (or the socket component on the charging base station side) during the docking process in the installed state, and the back side (or back side) refers to the side (or side) facing away from the charging base station (or the socket component on the charging base station side) during the docking operation in the installed state.

[0058] like Figure 5A and 5B As shown, the charging host side charging docking device (plug assembly) 210 includes: a plug mounting plate 214, on which a plug 213 is fixed. The plug 213 is an electrical connection plug, and the periphery of the plug 213 is provided with guide posts 211 and 212 extending toward the front side (negative Z-axis direction) along the board direction perpendicular to the plug mounting plate 214 (along the Z-axis direction). Figure 1B As shown, the plug assembly 210 is assembled on the charging host 20 by fixing the plug mounting plate 214 on the front side of the charging host 20 .

[0059] like Figure 5B , Figures 6A to 6D as well as Figures 7A to 7C As shown, when the rail-hanging robot 10 pushes the charging host 20 toward the charging base station 30 so that the plug assembly 210 approaches the socket assembly 400 for docking (insertion) operation, the guide columns 211 and 212 cooperate with the guide holes 433 on the socket assembly 400 to achieve guiding and positioning functions.

[0060] Specifically, guide post 211 is a circular guide post having the following structure: the head is conical for guiding; the middle is thick cylindrical for positioning; and the bottom is a thin cylindrical with a smaller radius than the middle, to avoid over-positioning caused by too long a positioning surface, which results in excessive insertion and extraction force. Guide post 212 is a trimming guide post having the following structure similar to circular guide post 211: the head is conical, the middle is thick cylindrical, and the bottom is a thin cylindrical with a smaller radius than the middle. In addition, two of the left and right end faces of the circumference of the middle cylinder of the trimming guide post 212 are trimmed. As a preferred method, the circumference of the middle cylinder of the trimming guide post 212 can be trimmed at two locations, such as Figure 7CAs shown, the end faces on the left and right sides of the circumference of the middle cylinder are trimmed to form trimmed end faces 212C. However, the position of the trimmed end faces 212C is not limited thereto. For example, the left or right side of the circumference of the middle cylinder in the installed state may also be trimmed. The trimming of the middle cylinder is performed to avoid over-positioning due to excessive deviation in the accuracy of the two guide pins, which may lead to excessive insertion and extraction force, thereby causing malfunction or damage.

[0061] In summary, the charging docking device for a charging host of the present invention has a simple structure, high docking accuracy and reliability, and prolongs the service life of the docking interface.

[0062] Although the present invention has been described above with reference to exemplary embodiments, the above embodiments are only for illustrating the technical concept and features of the present invention and cannot be used to limit the protection scope of the present invention. Any equivalent variations or modifications made according to the spirit and essence of the present invention should be included in the protection scope of the present invention.
