Description

TECHNICAL FIELD

[0001] The utility model relates to the field of hanging rail robot charging, especially relates to the charging docking device, charging base station and charging host computer for the butt joint of hanging rail robot and charging base station. BACKGROUND

[0002] With the popularity of new energy vehicles, the construction of charging infrastructure has become an important link for countries to promote green transportation development. However, due to the limited domestic parking resources, the charging demand of new energy vehicles still depends on the extensive layout of public charging piles. However, the existing fixed charging pile form and parking lot status make the utilization rate of a single charging pile decline, resulting in a decline in resource utilization.

[0003] There are some types of hanging rail type charging robots on the market at present, which try to optimize the charging process by changing the layout and operation mode of the charging pile. The existing hanging rail type mobile robot system usually includes a track, a mobile robot, a charging host computer and a charging base station. In order to achieve the purpose of flexible charging, the hanging rail type charging robot needs to carry the charging host computer and dock with the fixed charging base station. However, the high load of the charging host computer and the positioning error of the mobile robot will cause the docking error between the charging host computer and the charging base station to be too large, and thus the charging host computer will fail in the task of placing the pile. Among them, the docking error refers to the centering size deviation relative to the theoretical plugging position when the plug-in connector (such as the plug assembly and the socket assembly, or the dynamic plug-in connector and the static plug-in connector) performs the plugging action during the docking process of the charging host computer and the base station. Chinese patent application No. CN118323763A discloses a hanging rail type charging robot, which adopts a two-stage telescopic mechanism to reduce the docking error and thus realize the task of placing the pile by the charging host computer. However, the docking error cannot be avoided, so there is still a certain risk of damage to the docking interface between the host computer and the base station.

[0038] [Structure of charging base side charging docking device]

[0039] For the convenience of description, the posture of the charging docking device in the installed state is described below. Wherein, the front face (or front side, front side) refers to the face (or side) facing the charging device (or the plug assembly on the side of the charging device) during the docking process in the installed state, and the back face (or back side, back side) refers to the face (or side) facing away from the charging device (or the plug assembly on the side of the charging device) during the docking operation in the installed state.

[0040] The structure of the charging base side charging docking device (also referred to as static charging docking device) according to the utility model is described below with the socket assembly as an example of the charging base side charging docking device. As shown in FIG. 2A and FIG. 2B and FIG. 3A and FIG. 3B , the charging docking device (socket assembly) 400 for the charging base comprises a socket 410, a socket mounting plate 420 and a floating plate 430. Wherein, the socket mounting plate 420 is in the form of a box with an open back. In this embodiment, the socket mounting plate 420 is in the form of a rectangular box, and obviously the utility model is not limited thereto, and can also be in other shapes, for example, in the form of a circular, prismatic or oval cross-section box.

[0041] The socket 410 is fixed to the floating plate 430. The socket 410 can be an electrical socket, and as an alternative, it can be made separately from the floating plate 430 and fixed to the floating plate 430 by a fixing mechanism, or it can be made in one piece with the floating plate 430. As an example, as shown in Figs. 1A and 1B, a rectangular opening matching the shape of the bottom of the socket 410 is formed in the center of the floating plate 430, and the socket 410 can be fixed to the floating plate 430 in a state of being embedded in the rectangular opening. FIG. 2A and 3A As shown in Figs. 1A and 1B, a rectangular opening matching the shape of the bottom of the socket 410 is formed in the center of the floating plate 430, and the socket 410 can be fixed to the floating plate 430 in a state of being embedded in the rectangular opening.

[0042] An opening area 422 is formed in the center of the main plate 421, which is the front surface of the flat box (the surface that is butted against the charging main unit in the mounted state), of the socket mounting plate 420, and the floating plate 430 is assembled in a suspended manner inside the socket mounting plate 420 in a state of exposing the socket 410 from the opening area 422, so that the socket 410 on the floating plate 430 can float within the range of the opening area 422 of the main plate 421.

[0043] As shown in Figs. 1A and 1B, a rectangular opening matching the shape of the bottom of the socket 410 is formed in the center of the floating plate 430, and the socket 410 can be fixed to the floating plate 430 in a state of being embedded in the rectangular opening. FIG. 2A As shown in Figs. 1A and 1B, a rectangular opening matching the shape of the bottom of the socket 410 is formed in the center of the floating plate 430, and the socket 410 can be fixed to the floating plate 430 in a state of being embedded in the rectangular opening.

[0044] In addition, the charging butting device 400 further includes a floating baffle 430, which is arranged at 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 connected between the floating plate 430 and the socket mounting plate 420. As a preferred example, as shown in Figs. 1A and 1B, 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 can be connected to the edge of the floating baffle 450. FIG. 2A FIG. 4B 4D and 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 can be connected to the edge of the floating baffle 450.

[0045] As a preferred mode, a floating baffle opening 454 can also be formed in the center of the floating baffle 450, and the floating plate 430 and the socket 410 can float within the range of the floating baffle opening 454. The shape of the floating baffle opening 454 can be, for example, a rectangle as shown in Fig. 1C, and 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 of the socket 410 to connect the wiring harness behind the socket. FIG. 2A As a preferred mode, a floating baffle opening 454 can also be formed in the center of the floating baffle 450, and the floating plate 430 and the socket 410 can float within the range of the floating baffle opening 454. The shape of the floating baffle opening 454 can be, for example, a rectangle as shown in Fig. 1C, and 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 of the socket 410 to connect the wiring harness behind the socket.​​

[0046] As an alternative, one end of each tension spring 440 can be connected at the peripheral edge of the rectangular opening of the floating plate 430, and the other end of each tension spring 440 can be connected at the periphery of the rectangular opening region 422 of the main plate 421. By the elastic force of the tension spring 440, relative floating of the two connected parts (e.g., the floating baffle 450 and the floating plate 430, or the floating plate 430 and the socket mounting plate 420) in the direction parallel to the plane of the main plate 421 (e.g., the plane direction formed by the X-axis and the Y-axis shown in FIG. 1) can be achieved. FIG. 5B

[0047] As an example, the number of tension springs 440 can be 4, and obviously the number is not limited to this, but can also be 2, 3, 6, 8, etc.

[0048] In addition, as shown in FIGS. 1 and 2, in the case of connecting the tension spring 440 between the floating plate 430 and the floating baffle 450, the following structure can be adopted. On the periphery of the opening of the floating plate 430, for example, as shown in FIG. 1, four tension spring first mounting posts 431 are provided in pairs on both sides of the opening. The tension spring first mounting post 431 can be in the form of a stepped bolt, and correspondingly, a threaded hole is provided on the floating plate 430 at the position where the tension spring first mounting post 431 is to be mounted, as a tension spring first mounting hole 432, to mount the stepped bolt 431 on the threaded hole 432, so that the tension spring first mounting post 431 is connected with the tension spring first mounting hole 432. As an alternative, the tension spring first mounting post 431 can be integrally formed on the floating plate 430, in which case the tension spring first mounting hole does not need to be provided. FIG. 2A 3A FIG. 2A Correspondingly, four tension spring second mounting posts 451 are provided on the floating baffle 450, and the position of the tension spring second mounting post 451 on the floating baffle 450 is offset from the position of the tension spring first mounting post 431 on the floating plate 430 by a distance greater than the natural length of the tension spring 440. The tension spring second mounting post 451 is connected with a tension spring second mounting hole 452. The structure of the tension spring second mounting post and the tension spring first mounting post is similar, and as an alternative, the tension spring first mounting post and the tension spring second mounting post can be in the form of a bolt or a press-in rivet post.

[0049]

[0050] ​​​​By the above, the socket 410 is assembled in the opening area 422 of the socket mounting plate 420, and the floating plate 430 is elastically suspended on the inner side of the socket mounting plate 420, so that the socket 410 of the socket assembly 400 can move within the range of the opening area 422 during the process of being connected with the plug 213 of the plug assembly 210 (the plug 213 is inserted into the socket 410), and can be reset by the elastic force of the tension spring 440 in the state of being disconnected (the plug 213 is pulled out of the socket 410). That is, it can be achieved that after the plug assembly 210 of the charging device 20 is pulled out (as shown in FIG. 5A and FIG. 5B indicated), the socket 410 and the floating plate 430 of the socket assembly 400 are automatically centered (centered) relative to the opening area 422 of the socket mounting plate 420, thereby ensuring the normal connection (connection operation) next time.

[0051] As a preferred mode, as shown in FIG. 2C , the upper end and the lower end of the floating plate 430 extend downward and downward respectively in the vertical direction to partially overlap the upper and lower side end portions of the floating baffle 450, so that when the charging host 20 is pushed to the charging docking device 400 side to perform the docking operation of the charging docking device (socket assembly) 400 and the plug assembly 210 on the charging host 20 (as shown in 5A), the stop portion 435 cooperates with the back side of the floating baffle 450 to play a role of floating support for the floating plate 430 or the socket 410 in the direction perpendicular to the plate surface of the main plate 421 (the direction in which the charging host 20 is pushed to the charging docking device 400 side).

[0052] In addition, as a further preferred mode, the floating plate 430 can be assembled in a manner that can be elastically expanded and contracted in the direction perpendicular to the plate surface of the main plate 421, so that the floating plate can move in the direction parallel to the plate surface of the main plate and in the direction perpendicular to the plate surface of the main plate. Specifically, as shown in FIG. 3A and FIG. 4A to FIG. 4E , the charging docking device (socket assembly) 400 further comprises 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 in a posture with the axis perpendicular to the floating baffle 450, and the other end of the compression spring 460 is fixed to the front surface of the charging host. As a preferred mode, as shown in FIG. 2A , FIG. 3A and FIG. 5A , the socket assembly 400 of the utility model further comprises a rear baffle 470 arranged on the back side of the floating baffle 450. Among them, the compression spring 460 fixes its two ends on the floating baffle 450 and the rear baffle 470 respectively in a posture with the axis perpendicular to the floating baffle 450, so as to realize the floating baffle 450 relative to the rear baffle 470 along the direction perpendicular to the plate surface of the rear baffle 470 (along the directionFIG. 5B relative floating (in the Z-axis direction) of the floating plate 430 with respect to the socket 410.

[0053] Specifically, the rear baffle 470 is provided with four rear baffle mounting holes 471, and is fixedly connected with the socket mounting plate 420 by, for example, screws 474. Also, as shown in FIG. 3B the rear baffle 470 is provided with four compressed spring second mounting posts 472 for connecting with the compressed spring 460. Correspondingly, the floating baffle 450 is provided with four compressed spring first mounting posts 453 for connecting with one end of the compressed spring 460. As an optional manner, the compressed spring first mounting posts or the compressed spring second mounting posts can be in the form of bolts or rivets. Preferably, the rear baffle 470 is provided with a rear baffle opening 473 (as shown in FIG. 2A and 2B so that 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 of the socket 410 to connect the wiring harness behind the socket.

[0054] As an example, the number of the compressed springs 460 is four, as shown in FIG. 3A and 4D Obviously, the utility model is not limited to this, and the number of the compressed springs 460 can be two, six, eight, etc. according to the shape of the mounting box.

[0055] As a further preferred manner, a limiting part 455 is arranged on the floating baffle 450 at a position corresponding to the outside (left and right sides) of the detent part 435 of the floating plate 430, in a manner that the limiting part 455 is spaced apart from the outer end edge of the detent part 435 by a certain distance. The distance is greater than the floating range, which is set according to the deviation amount when the charging docking device on the charging host side is docked with the charging docking device on the charging base side. As a preferred example, the limiting part 455 can be in the form of a step that protrudes forward from the front surface (the side surface of the two pairs of floating plates 430) of the floating baffle 450, as shown in FIG. 2C .

[0056] In addition, the height of the limiting part (step) 455 is greater than the thickness of the detent part 435 of the floating plate 430, so that in the natural state when the docking is not performed (the socket assembly 400 and the plug assembly 210 are not plugged), the floating baffle 450 is pressed on the socket mounting plate 420 by the compressed spring 460, and the inner end surface of the step 455 is in contact with the floating plate 430, so that the floating plate 430 can not only move in the left-right direction within the range defined by the limiting part 455, but also enables the floating plate 430 and the detent part 435 to float forward and backward within the space between the limiting part 455 of the floating baffle 450 and the socket mounting plate 420.

[0057] As a preferred example, the shape of the stop portion 435 can be, for example, as shown in the example... FIG. 2A The rectangles shown are four in number, but obviously the present invention is not limited to this. Their shapes can be, for example, semicircles or semi-ellipses, with their straight edges located on the left and right ends of the floating plate 430 to be opposite to the limiting part 455 of the floating baffle 450. The number of the baffles 435 can be, for example, two, with one arranged at the upper end and one at the lower end of the floating plate 430.

[0058] 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 device during the docking process. In addition, with the reset 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 charging device 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.

[0059] 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 plate 430. Preferably, the guide post 434 can be arranged around the periphery of the socket 410, for example, on the left and right sides of the socket 410. Furthermore, a guide hole 433 is provided along the axis of the guide post 434. FIG. 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.

[0060] 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.

[0061] Therefore, the charging docking device of this utility model, by adopting a structure of suspending and assembling floating plates, can automatically and passively straighten the charging host with positioning deviation, which can avoid damage to the docking interface caused by docking deviation due to software positioning error and structural installation error.

[0062] like FIG. 3BAs shown, as a preferred embodiment, thin pins and thick pins are provided on the socket 410, wherein the thin pins connect signal lines and are arranged at the center of the socket, and the thick pins connect power supply lines and are arranged at the outer periphery of the thin pins. Preferably, the thick pins can be arranged on the left and right sides of the thin pins (as shown in FIG. 2B As shown, the thick pins can also be arranged on the upper and lower sides of the thin pins, or the thick pins are arranged to surround the periphery of the thin pins.

[0063] In addition, the thick pins of the socket 410 can include at least one of an alternating current pin and a direct current pin. As a preferred mode, both the alternating current pin and the direct current pin are included to enable the charging equipment with the charging docking device of the present application to simultaneously complete the functions of bidirectional power supply and signal transmission. For example, 380V power supply from the charging base station to the charging host can be performed via the alternating current pin, and direct current power supply from the charging host to the charging base station can be performed via the direct current pin.

[0064] By providing thin pins connecting signal lines and thick pins connecting power supply lines, the charging docking device according to the present application can simultaneously perform 380V power supply from the base station to the charging host, direct current power supply from the charging host to the charging base station, and also can simultaneously perform various signals of the charging gun itself and the interaction with the charging host (such as temperature, vehicle BMS signal).

[0065] In the embodiment of the present application, as shown, FIG. 3B The number of thin pins is 24, arranged in a 4x6 array, and the thick pins are divided into two groups, each group having four and arranged in a 2x2 array. Obviously, the above structure is only an example, and the present application is not limited thereto. According to different configurations of the power supply circuit and the signal circuit of the overhead rail robot or the charging host, appropriate configurations can be taken for the number and arrangement of the thin pins and the thick pins.

[0066] In addition, as shown, FIG. 1A The charging docking device 400 according to the present application can be installed on the charging base station 30 or fixed on the power distribution box 40 on the side opposite to the charging host 20. The plug assembly 210 is assembled on the side opposite to the charging base station 30.

[0067] 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 is described below in connection with the structure of the plug assembly 210.

[0068] In summary, the charging docking device for the charging base station has simple structure, high docking precision and reliability. In addition, the charging docking device for the charging base station can float in a certain range in a plane perpendicular to the docking movement, and if the robot positioning is deviated, the self-adaptability can be used to automatically correct the position deviation, thereby improving the success rate of docking and prolonging the service life of the docking interface.

[0069] [Structure of the charging docking device on the charging host side]

[0070] The following takes the plug assembly as an example of the charging docking device on the charging host side, and the structure of the charging docking device on the charging host side (which can also be called a dynamic charging docking device) according to the utility model is described with reference to FIG. 5A and FIG. 5B , FIG. 6A to FIG. 6D and FIG. 7A to FIG. 7C .

[0071] For ease of description, the following describes the posture of the charging docking device on the charging host side in the installed state. Among them, the front face (or front side) refers to the face (or side) facing the charging base station (or the socket assembly on the charging base station side) during the docking process in the installed state, and the back face (or back side) refers to the face (or side) facing away from the charging base station (or the socket assembly on the charging base station side) during the docking operation in the installed state.

[0072] As shown in FIG. 5A and 5B , the charging docking device on the charging host side (plug assembly) 210 includes a plug mounting plate 214 on which a plug 213 is fixed. Among them, the plug 213 is an electrical connection plug, and guide columns 211 and 212 are provided on the periphery of the plug 213 and protrude forward (negative Z-axis direction) along the direction perpendicular to the plate surface of the plug mounting plate 214 (along the Z-axis direction). As shown in FIG. 1B , the plug assembly 210 is assembled on the charging host 20 by fixing the plug mounting plate 214 on the front face of the charging host 20.

[0073] As shown in FIG. 5B , FIG. 6A to 6D and FIG. 7A to 7C , when the overhead rail robot 10 pushes the charging host 20 to the charging base station 30 side to make the plug assembly 210 close to 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 realize the guiding and positioning functions.

[0074] Specifically, the guide pillar 211 is a round guide pillar, which has the following structure: the head is conical for guiding function; the middle part is thick cylindrical for positioning function; and the bottom is thin cylindrical with smaller radius than the middle part to avoid over-positioning caused by too long positioning surface, which results in too large insertion force. The guide pillar 212 is a chamfered guide pillar, which has the similar structure as the round guide pillar 211: the head is conical, the middle part is thick cylindrical, and the bottom is thin cylindrical with smaller radius than the middle part. In addition, two end faces of the left and right sides of the circumference of the middle cylindrical part of the chamfered guide pillar 212 are chamfered. As a preferred mode, two places of the circumference of the middle cylindrical part of the chamfered guide pillar 212 can be chamfered, such as shown in FIG. 7C The left and right end faces of the circumference of the middle cylindrical part are chamfered to form chamfered end faces 212C. However, the position of the chamfered end faces 212C is not limited to this, for example, one side of the left or right side of the circumference of the middle cylindrical part in the mounted state can be chamfered. The middle cylindrical part is chamfered to avoid over-positioning caused by too large precision deviation of the two guide pillars, which results in too large insertion force, thereby causing failure or damage.

[0075] In summary, the charging docking device for the charging host has simple structure, high docking precision and reliability, and prolongs the service life of the docking interface.
