Description

[0001] This application is a divisional application of the invention patent application with application number 202510018794.2, application date January 6, 2025, and invention title "Charging docking device, charging base station and charging host". Technical Field

[0002] This invention relates to the field of charging for track-mounted robots, and more particularly to a charging docking device, a charging base station, and a charging host for docking track-mounted robots with a charging base station. Background Technology

[0004] Currently, several types of rail-mounted charging robots exist on the market, attempting to optimize the charging process by altering the layout and operation of charging stations. Existing rail-mounted mobile robot systems typically include a track, a mobile robot, a charging host, and a charging base station. To achieve flexible charging, the rail-mounted charging robot needs to carry the charging host and dock with a fixed charging base station. However, the high load on the charging host and the positioning error of the mobile robot can lead to excessive docking errors between the charging host and the charging base station, resulting in the failure of the charging host's placement task. The docking error refers to the deviation in centering dimensions relative to the theoretical insertion / removal position when connectors (e.g., plug and socket components, or dynamic and static connectors) are inserted or removed during the docking process between the charging host and the base station. Chinese patent application CN118323763A discloses a rail-mounted charging robot that employs a two-stage telescopic mechanism to reduce docking errors, thereby enabling the charging host to be placed in the charging station. However, docking errors are still unavoidable, therefore, the docking interface between the host and the base station still carries a certain risk of damage.

Detailed Implementation

[0035] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative configuration of components, numerical representations, and values ​​described in these embodiments does not limit the scope of the invention. For simplicity, the same reference numerals or designations are used for the same structural parts or steps, and their descriptions are omitted.

[0036] 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 capable of providing electricity, such as a distribution box.

[0037] As shown in Figure 1, the rail-mounted charging system 1 includes a guide rail 50 arranged above the parking space. Multiple charging base stations 30 are arranged along the guide rail 50, corresponding to the positions of the parking spaces. Each charging base station 30 is equipped with a power distribution box 40. A rail-mounted robot 10 can travel along the guide rail 50, carrying and transporting a charging host 20 along the guide rail 50. When charging is required, the rail-mounted robot 10 carries the charging host 20 to a specific charging base station 30. The robot pushes the charging host 20 to the side of the charging base station 30, and the charging interface (e.g., plug assembly 210) on the charging host 20 connects with the charging interface (charging docking device, e.g., socket assembly) on the charging base station to form an electrical connection. After successful docking between the charging base station 30 and the charging host 20, the charging base station 30 can provide AC power to the charging host 20, and the charging host 20 can provide DC power to the charging base station 30.

[0038] The following is for reference Figures 2A to 2C , Figure 3A and Figure 3B as well as Figures 4A to 4E The structure of the charging base station side charging docking device (socket assembly) according to the present invention for docking with the charging host side charging docking device (plug assembly) mounted on the rail robot will be described.

[0039] [Structure of the charging docking device on the charging base station side]

[0040] For ease of description, the following describes the orientation of the charging docking device in the installed state. Here, "front" (or "front side") refers to the side (or side) facing the charging device (or the plug assembly on the charging device side) during docking in the installed state, while "back" (or "back side") refers to the side (or side) facing away from the charging device (or the plug assembly on the charging device side) during docking in the installed state.

[0041] The following description uses a 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 (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 a box-shaped structure with an open back. In this embodiment, the socket mounting plate 420 is a rectangular box shape, but the invention is obviously not limited to this; it can also be other shapes, such as a box-shaped structure with a circular, prismatic, or elliptical cross-section.

[0042] The socket 410 is fixed to the floating plate 430. The socket 410 can be an electrical socket; alternatively, it can be manufactured separately from the floating plate 430 and fixed to it via a fixing mechanism, or it can be integrated with the floating plate 430. As an example, such as... Figure 2A and 3A As shown, a rectangular opening matching the bottom shape of the socket 410 is provided in the center of the floating plate 430, so that the socket 410 can be fixed on the floating plate 430 in a state of being embedded in the rectangular opening.

[0043] An opening area 422 is provided in the center of the main board 421 of the socket mounting plate 420, which serves as the front of the flat box (the side that docks with the charging host in the installed state). The floating plate 430 is mounted inside the socket mounting plate 420 in a suspended manner 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 opening area 422 of the main board 421.

[0044] Among them, as a preferred method, such as Figure 2A As shown, the opening area 422 of the motherboard 421 is hexagonal. Obviously, the present invention is not limited to this. The shape of the opening area 422 can also be a rectangle, ellipse, rounded or obtuse rectangle, etc., that matches the shape of the mating part of the socket 410 so that the mating part of the socket 410 can be exposed from the opening area 422 and have a certain amount of room to move.

[0045] Furthermore, the charging docking device 400 also includes a floating baffle 450, which is arranged on the back (rear) side of the floating plate 430. The suspension mechanism for the floating plate 430 can be implemented, for example, by a tension spring 440. 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, as shown in FIG2, one end of each tension spring 440 is connected to the periphery of the rectangular opening of the floating plate 430, while the other end of each tension spring 440 can be connected to the edge of the floating baffle 450.

[0046] As a preferred embodiment, a floating baffle opening 454 can also be provided at the center of the floating baffle 450, allowing the floating plate 430 and the socket 410 to float within the range of the floating baffle opening 454. The shape of the floating baffle opening 454 can be, for example, as shown below. Figure 2A As shown in the diagram, the other end of each tension spring 440 can be connected to the periphery of the rectangular opening of the floating baffle 450. Furthermore, the floating baffle opening 454 facilitates the routing of wiring from the socket 410 for connecting the wiring harness at the rear of the socket.

[0047] Alternatively, one end of each tension spring 440 can be connected to the periphery of the rectangular opening of the floating plate 430, while the other end of each tension spring 440 can be connected to the periphery of the rectangular opening area 422 of the main board 421. Through the elastic force of the tension springs 440, the connected components (e.g., floating baffle 450 and floating plate 430, or floating plate 430 and socket mounting plate 420) can be aligned in a direction parallel to the surface of the main board 421 (e.g.,...). Figure 5B The relative floating in the plane direction formed by the X-axis and Y-axis shown in the figure.

[0048] For example, the number of tension springs 440 can be 4, but obviously the number is not limited to this, and can also be 2, 3, 6, 8, etc.

[0049] In addition, such as 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. Around the opening of the floating plate 430, for example... Figure 2A As shown, four tension spring first mounting posts 431 are arranged in pairs on the left and right sides of the opening. The tension spring first mounting posts 431 can be made using stepped bolts. Correspondingly, threaded holes are made in the floating plate 430 at the corresponding positions where the tension spring first mounting posts 431 are to be installed, serving as tension spring first mounting holes 432. The stepped bolts 431 are then installed in the threaded holes 432, thereby connecting the tension spring first mounting posts 431 to the tension spring first mounting holes 432. Alternatively, the tension spring first mounting posts 431 can be integrally manufactured on the floating plate 430, in which case it is unnecessary to create tension spring first mounting holes.

[0050] Correspondingly, four second mounting posts 451 for tension springs are provided on the floating baffle 450. The distance between the second mounting posts 451 on the floating baffle 450 and the first mounting posts 431 on the floating plate 430 is greater than the natural length of the tension spring 440. The second mounting posts 451 are connected to the second mounting holes 452. The structures of the second and first mounting posts are similar. Optionally, the first and second mounting posts can be bolted or riveted.

[0051] By assembling the socket 410 within the opening area 422 of the socket mounting plate 420 and elastically suspending the floating plate 430 inside the socket mounting plate 420, the socket 410 of the socket assembly 400 can move within the opening area 422 during the process of mating with the plug 213 of the plug assembly 210 (the plug 213 is inserted into the socket 410), and can return to its original position by the elastic force of the tension spring 440 when the mating is disengaged (the plug 213 is pulled out of the socket 410). In other words, the plug assembly 210 of the charging device 20 can achieve... Figure 5A and Figure 5B As shown, after being pulled out, the socket 410 and floating plate 430 of the socket assembly 400 automatically return to center (align) relative to the opening area 422 of the socket mounting plate 420, thereby ensuring normal connection (connection operation) in the next plugging and unplugging operation.

[0052] As a preferred method, such as Figure 2C As shown, the upper and lower ends of the floating plate 430 extend upward and downward in the vertical direction respectively to overlap with the upper and lower end portions of the floating baffle 450. This allows the stop portion 435 to provide floating support for the floating plate 430 or the socket 410 in the direction perpendicular to the surface of the main board 421 (the direction in which the charging host 20 is pushed towards the charging docking device 400) when the charging docking device (socket assembly) 400 is pushed towards the plug assembly 210 on the charging host 20 (as shown in 5A).

[0053] Furthermore, as a further preferred embodiment, the floating plate 430 can be assembled in a manner that allows it to elastically extend and retract in a direction perpendicular to the surface of the main plate 421. Specifically, as... Figure 3A as well as Figures 4A to 4E As shown, the charging docking device (socket assembly) 400 also 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 embodiment, such as 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 disposed on the back side of the floating baffle 450. A compression spring 460 is fixed at both ends to the floating baffle 450 and the rear baffle 470 respectively, with its axis perpendicular to the floating baffle 450, so that its elastic force allows the floating baffle 450 to move relative to the rear baffle 470 in a direction perpendicular to the surface of the rear baffle 470 (along...). Figure 5B The relative floating of the Z-axis direction.

[0054] Specifically, the rear panel 470 has four rear panel mounting holes 471, which are used to connect to the socket mounting plate 420 via, for example, screws 474, thereby fixing the rear panel 470 to the socket mounting plate 420. Furthermore, as... Figure 3B As shown, four second compression spring mounting posts 472 are provided on the rear baffle 470 for connecting to the compression spring 460. Correspondingly, four first compression spring mounting posts 453 are provided on the floating baffle 450 for connecting to one end of the compression spring 460. Preferably, the first or second compression spring mounting posts can be bolted or riveted. Preferably, the rear baffle 470 has a rear baffle opening 473 (e.g., ...). Figure 2A and 2B As shown, this allows the floating plate 430 and the socket 410 to float within the range of the rear panel opening 473. Furthermore, the rear panel opening 473 facilitates the routing of wiring from the socket 410 for connecting wiring harnesses at the rear of the socket.

[0055] As an example, such as Figure 3A and 4D As shown, there are four compression springs 460. However, this invention is clearly not limited to this; depending on the shape of the mounting box, the number of compression springs 460 can also be two, six, eight, etc.

[0056] As a further preferred embodiment, a limiting part 455 is provided at a position on the floating baffle 450 corresponding to the outer side (left and right sides) of the blocking part 435 of the floating baffle 430, at a certain distance from the outer edge of the blocking part 435. This distance is greater than the floating range, which is set according to the deviation when the charging docking device on the charging host side and the charging docking device on the charging base station side are docked. As a preferred example, such as Figure 2C As shown, the limiting part 455 can be in the form of a step that extends forward from the front of the floating baffle 450 (the sides of the two pairs of floating plates 430).

[0057] Furthermore, the height of the limiting part (step) 455 is greater than the thickness of the stop part 435 of the floating plate 430, so that in the natural state of not being connected (the socket assembly 400 and the plug assembly 210 are not connected), the floating baffle 450 is pressed onto the socket mounting plate 420 by the compression spring 460, and the inner end face 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 part 455, but also allows the floating plate 430 and the stop part 435 to float back and forth in the space between the limiting part 455 of the floating baffle 450 and the socket mounting plate 420.

[0058] As a preferred example, the shape of the stop portion 435 can be, for example, as shown in the example... Figure 2AThe rectangles shown are four in number, but the invention is obviously not limited to this; their shapes can be, for example, semicircles or semi-ellipses, with their straight edges located at the left and right ends of the floating plate 430 to face the limiting portions 455 of the floating baffle 450. The number of baffle portions 435 can be, for example, two, with one arranged at the upper end and one at the lower end of the floating plate 430.

[0059] By setting the limiting part 455 and the stop part 435, the movement range of the socket 410 or the floating plate 430 in the direction parallel to the main board 421 can be limited, providing a certain amount of redundancy for the alignment of the charging equipment during the docking process. In addition, with the reset force provided by the tension spring 440, the docking posture of the charging equipment can be corrected, so that the plug assembly 210 of the charging equipment being docked is facing the charging docking device (socket assembly 400) on the charging base station side, thereby improving the ease of operation, accuracy and reliability of charging docking.

[0060] As a further preferred embodiment, the floating plate 430 is provided with guide posts 434 protruding forward in a direction perpendicular to the surface of the main plate 421. Preferably, the guide posts 434 can be arranged around the periphery of the socket 410, for example, on the left and right sides of the socket 410. Furthermore, guide holes 433 are formed along the axis of the guide posts 434. Figure 3A As shown, two guide posts 434 and two guide holes 433 are provided. The guide holes 433 cooperate with the guide posts 434 to achieve the guiding and positioning function. This 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.

[0061] In addition, wings extend to the left and right sides from 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. A first mounting hole 423 is provided on the wing for fixing to the charging base station 30 or the distribution box 40. A second mounting hole 424 extending to the back side (rear side) is provided on the inner side of the socket mounting plate for fixing to the rear baffle.

[0062] Therefore, the charging docking device of the present invention, by adopting a structure of suspending and assembling floating plates, can automatically and passively straighten the charging host with positioning deviation, thereby avoiding damage to the docking interface caused by docking deviation due to software positioning error and structural installation error.

[0063] like Figure 3B As shown, in a preferred embodiment, the socket 410 is provided with thin pins and thick pins. The thin pins connect to signal lines and are arranged in the center of the socket, while the thick pins connect to power supply lines and are arranged around the outer periphery of the thin pins. Preferably, the thick pins can be arranged on the left and right sides of the thin pins (e.g., Figure 2B(As shown), the thick pins can also be arranged on the top and bottom sides of the thin pins, or the thick pins can be arranged to surround the thin pins.

[0064] Furthermore, the thick pins of the socket 410 may include at least one of AC and DC power pins. Preferably, both AC and DC power pins are included, enabling the charging device with the charging docking device of the present invention to simultaneously perform bidirectional power supply and signal transmission functions. For example, the AC power pins can be used to supply 380V power from the charging base station to the charging host, while the DC power pins can be used to supply DC power from the charging host to the charging base station.

[0065] By setting fine 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 from the base station to the charging host, supply DC power from the charging host to the charging base station, and can also simultaneously perform various signal interactions between the charging gun itself and the charging host (e.g., temperature, vehicle BMS signals).

[0066] In embodiments of the present invention, such as Figure 3B As shown, there are 24 thin pins arranged in a 4×6 array, while the thick pins are divided into two groups of four, arranged in a 2×2 array. Clearly, the above structure is merely an example, and the invention is not limited thereto. Depending on the different configurations of the power supply and signal circuits of the rail-mounting mechanism or the charging host, appropriate configurations can be adopted for the number and arrangement of the thin and thick pins.

[0067] In addition, such as Figure 1A As shown, the charging docking device 400 according to the present invention can be installed on the charging base station 30 or fixed on the side of the power distribution box 40 on the charging base station 30 opposite to the charging host 20. A plug assembly 210 is fitted on the side of the charging host 20 opposite to the charging base station 30.

[0068] The following describes the process of docking between the charging docking device (socket assembly) 400 on the charging base station side and the charging docking device (plug assembly) 210 on the charging host side, in conjunction with the structure of the plug assembly 210.

[0069] In summary, the charging docking device for charging base stations of the present invention has a simple structure and high docking accuracy and reliability. Furthermore, the charging docking device for charging base stations of the present invention can float within a certain range in a plane perpendicular to the docking motion.

[0070] [Structure of the charging docking device on the charging host side]

[0071] The following example uses a plug-in assembly as a charging docking device on the charging host side. Figure 5A and Figure 5B , Figures 6A to 6D as well as Figures 7A to 7C The structure of the charging host-side charging docking device (also known as the dynamic charging docking device) according to the present invention will be described.

[0072] For ease of description, the following description refers to the orientation of the charging docking device in its installed state from the perspective of the charging host. Here, "front" (or "positive side") refers to the side (or side) facing the charging base station (or the socket assembly on the charging base station side) during docking in the installed state, while "back" (or "reverse side") refers to the side (or side) facing away from the charging base station (or the socket assembly on the charging base station side) during docking in the installed state.

[0073] 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 guide posts 211 and 212 are provided around the plug 213, extending forward (negative Z-axis direction) along a direction perpendicular to the surface of the plug mounting plate 214 (along the Z-axis direction). Figure 1B As shown, the plug assembly 210 is assembled onto the charging host 20 by fixing the plug mounting plate 214 to the front of the charging host 20.

[0074] like Figure 5B , Figures 6A to 6D as well as Figures 7A to 7C As shown, when the rail-mounted 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 posts 211 and 212 cooperate with the guide holes 433 on the socket assembly 400 to achieve guiding and positioning functions.

[0075] Specifically, guide post 211 is a circular guide post with the following structure: a conical head for guiding; a thick cylindrical middle section for positioning; and a thin cylindrical bottom with a smaller radius than the middle section to prevent over-positioning due to an excessively long positioning surface, which would result in excessive insertion and extraction forces. Guide post 212 is a chamfered guide post with a similar structure to circular guide post 211: a conical head, a thick cylindrical middle section, and a thin cylindrical bottom with a smaller radius than the middle section. Furthermore, two end faces of the central cylindrical section of chamfered guide post 212 are chamfered. Preferably, the two ends of the central cylindrical section of chamfered guide post 212 can be chamfered, such as... Figure 7CAs shown, the left and right end faces of the circumference of the central cylinder are cut to form cut end faces 212C. However, the position of the cut end faces 212C is not limited to this. For example, the left or right side of the circumference of the central cylinder in the installed state can also be cut. Cutting the central cylinder avoids over-positioning caused by excessive precision deviation between the two guide posts, which could lead to excessive insertion and extraction forces, causing malfunctions or damage.

[0076] In summary, the charging docking device for the charging host of the present invention has a simple structure, high docking accuracy and reliability, and extends the service life of the docking interface.
