  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, for convenience of explanation, in the embodiments of the present invention, an electric vehicle will be described by taking a bus as an example, a battery to be discharged is a discharge battery, and a fully charged battery is a fully charged battery. Commonly called.

  FIG. 1 is a perspective view showing a state where an electric vehicle replaces a battery in an automatic battery replacement system for an electric vehicle according to the present invention, and FIG. 2 is a side view of FIG.

  As shown in FIGS. 1 and 2, an electric battery is detachably attached to the rear side of the upper frame of the bus 2. That is, a battery mounting groove 10 for mounting an electric battery is formed on the rear side of the upper frame of the bus 2, and the battery mounting groove 10 is opened or closed by an opening / closing door 12 that slides back and forth. It is made up of.

  On the other hand, a lift frame 100 in which a horizontal frame 120 and a vertical frame 110 have a substantially letter shape is installed at a bus stop (or a specific battery exchange).

  Here, the vertical frame 110 of the elevating frame 100 is in charge of the function of the support base from the bottom, and the horizontal frame 120 is in charge of the function of the roof that protects passengers moving up and down on the bus at the landing from snow, rain and the like. In particular, the horizontal frame 120 is provided with a plurality of fully charged batteries, and takes charge of the function of replacing the battery scheduled to be discharged on the bus with a fully charged battery as necessary.

  FIG. 3 is a front view of FIG. 1 according to the first embodiment of the present invention, FIG. 4 is an internal configuration diagram showing the configuration and operation relationship of the automatic battery replacement system according to the first embodiment of the present invention, and FIG. FIG. 6 is an enlarged perspective view showing only the battery automatic replacement system of FIG. 4, and FIG. 6 is a partially enlarged perspective view of FIG.

  Referring to FIGS. 3 to 6, in the first embodiment of the present invention, a plurality of battery support bases 250 are installed on the bottom surface of the horizontal frame 120 over the entire area. A fully charged battery or a discharged battery B is detachably attached.

  At this time, when the number of the battery support bases 250 is n, it is preferable that not all the batteries are attached to the n battery support bases 250 and at least n−1 batteries are attached.

  For example, as illustrated in FIGS. 4 and 5, when the battery support bases 250 formed on the horizontal frame 120 of the elevating frame 100 are arranged in six horizontal rows and four vertical rows and a total of 24, 24 of these are provided. It is preferable that 24 batteries are not attached to each of the battery support bases 250, but only 23 batteries of at least 24-1 or less are attached.

  The reason for this is that when each battery is attached to each battery support base 250, after the bus 2 has entered and the discharged battery in the bus has been picked up, there is no space for mounting the battery. This is because the battery is not exchanged.

  Here, after the fully charged battery is transferred to a separate loading vehicle in the battery support base 250, it is attached to the battery support base 250 of the horizontal frame 120, and when these fully charged batteries are all replaced with discharge batteries, Moreover, what is necessary is just to replace | exchange a discharge battery with a fully charged battery using another loading vehicle.

  In addition, each of the battery support bases 250 is energized so that the discharge battery attached to the battery support base 250 is charged, so that the discharge battery and the fully charged battery can be exchanged. It can be eliminated.

  On the other hand, a pair of fixed guide rails 210 arranged in the horizontal direction are installed on the upper front side and the rear upper side of the horizontal frame 120, respectively, and the variable guide rails 220 that horizontally move along the fixed guide rails 210. Is installed.

  The variable guide rail 220 is provided with a moving rail 230 which is installed in the vertical direction and is moved up and down relative to the variable guide rail 220 and horizontally moved along the variable guide rail 220. A gripping means 240 for gripping the battery B is installed at the lower end of the moving rail 230.

  In the drawing, an unexplained symbol 200 is used to refer to the fixed guide rail 210, the variable guide rail 220, the moving rail 230, and the gripping means 240, and indicates a battery replacement system.

  For reference, in the first embodiment of the present invention, the fixed guide rails 210 are installed in a pair in the horizontal direction on the front upper side and the rear upper side of the horizontal frame 120, respectively, and the variable guide rail 220 is connected to the fixed guide rail 210. In some cases, the fixed guide rails 210 are installed side by side above the left and right surfaces of the horizontal frame 120, and the variable guide rails 220 are connected to the fixed guide rails 210. Of course, it can also be installed laterally.

  Also, the electric vehicle battery automatic replacement system 200 according to the first embodiment of the present invention, that is, the horizontal frame 120 on which a plurality of battery support bases 250 are installed, the fixed guide rail 210, the variable guide rail 220, and the moving rail 230 are provided. Is fixed at a specified position, but the bus 2 entering the landing is variable, and particularly precise position control is impossible, so that the grip of the moving rail 230 is performed according to the set absolute position. It would be very difficult for the means 240 to be always on the same vertical line as the battery seated in the mounting groove of the bus.

  That is, the bus 2 can stop at the set position along the guide stop line and be positioned in the position area for battery replacement, but the position is set correctly (the gripping means 240 of the moving rail 230 is set). It is important that the moving rail 230 finds the position of the battery mounted in the battery mounting groove 10 of the bus 2 and aligns it on the same vertical line.

  Here, in the first embodiment of the present invention, as shown in FIG. 11, the difference between the positions of the batteries mounted in the battery mounting groove 10 of the bus gripping means 240 and the gripping means 240 of the moving rail 230 is detected using an image recognition device. Then, the position correction data is transferred to the control unit, so that an accurate position on the same line is detected so that the gripping means 240 of the moving rail 230 is positioned on the same vertical line as the bus battery.

  Accordingly, a stop monitoring sensor unit that detects whether or not the bus has stopped at the stop line, and whether or not the battery that has been stopped and the battery mounted in the battery mounting groove 10 has been positioned in the moving region of the moving rail 230 are detected. And an image sensing unit for sensing in which range the battery mounted in the battery mounting groove 10 is located from the absolute position of the moving rail 230.

  In addition, an operation signal is applied to driving means for driving the variable guide rail 220 and the moving rail 230 according to a signal detected from the image sensing unit, and the gripping means 240 of the moving rail 230 is connected to the battery mounting groove 10. A control unit is further included so as to be positioned on the same vertical line.

  Here, the controller is connected to each of the battery support bases 250 to determine whether or not the battery is seated, and to determine whether the battery seated on the battery support base 250 is fully charged. Also responsible for functions.

  Accordingly, the discharge battery picked up from the electric vehicle (bus) is transferred to the empty battery support 250, and only the fully charged battery is transferred to the electric vehicle so that the variable guide rail 220 and the moving rail 230 are transferred. It is also in charge of the function of controlling the driving means.

  The image sensing unit processes a CCD camera that captures whether or not the bus is stopped and the battery mounting groove 10 is positioned in the moving region of the moving rail 230, and an image signal input from the CCD camera. Position correction value based on video information processing section, memory section for storing reference value for position correction, and reference value stored in memory section and bus stop position detected by video information processing section And an operation signal for driving the positions of the variable guide rail 220 and the moving rail 230 from the absolute position to the correction position based on the position correction value calculated by the calculation unit. Is applied to the driving means.

  For reference, in order to minimize errors that occur during image recognition by the image recognition device, two or more CCD cameras are placed on a diagonal line, and the data extracted from each CCD camera is compared to calculate position data. Preferably, the memory unit stores a preset absolute position.

  The operational relationship of the electric vehicle battery automatic replacement system according to the first embodiment of the present invention configured as described above will be described as follows.

  First, when the fully charged battery or the fully charged battery and the discharge battery are attached to the battery support 250 of the horizontal frame 120, the bus 2 enters the landing and inputs a signal for battery replacement. The discharge battery will be replaced with a fully charged battery.

  That is, after the bus 2 enters the landing and stops along the stop line, a battery replacement signal is input, and the open / close cover 12 of the battery mounting groove 10 is opened to activate the image recognition device and the control unit. After the position of the moving rail 230 is corrected, the gripping means 240 installed at the lower end of the moving rail 230 moves on the same vertical line as the battery mounted in the mounting groove 10 of the bus. This is as follows.

  When the bus 2 enters the landing and stops along the stop line, and the opening / closing cover 12 of the battery mounting groove 10 is opened, the battery mounted in the battery mounting groove 10 comes close to the gripping means 240 of the moving rail 230. When the image recognition apparatus comes to be positioned on the same vertical line, the image recognition apparatus sends it to the control unit to correct the position of the moving rail 230.

  That is, if an image in which the position of the battery mounting groove 10 taken by the CCD camera is not located on the same vertical line as the gripping means 240 of the moving rail 230 is taken and transmitted to the video information processing unit, the taken position and the current moving rail The gripping means 240 of 230 is located, the coordinate value of the absolute position is calculated by the calculation unit and transmitted to the control unit, and the control unit corrects the variable guide rail 220 and the moving rail 230 by the driving unit by the transmitted coordinate value. By applying the operation signal so as to move to a different position, the battery mounted in the battery mounting groove 10 of the bus and the gripping means 240 of the moving rail 230 are corrected so as to be located on the same vertical line.

  That is, the variable guide rail 220 moves in the X-axis or Y-axis direction along the pair of fixed guide rails 210 by the application of the drive signal of the driving means by the control unit, and the movable rail 230 moves along the variable guide rails 220. By moving in the Y-axis or X-axis direction, the gripping means 240 installed at the lower end of the moving rail 230 is moved to a position coinciding with the battery mounting groove 10 of the bus, thereby correcting the position.

  Thus, if the variable guide rail 220 and the moving rail 230 move and the gripping means 240 of the moving rail 230 is positioned on the same vertical line as the battery mounted in the battery mounting groove 10 of the bus, the moving rail 230 After the gripping means 240 is lowered and lifted in a state where the battery is gripped, the discharged battery is moved to the empty battery support 250 applied by the control unit from the battery support 250 of the horizontal frame 120 and discharged. If the fully charged battery applied by the control unit is held by the above method and then moved to the battery mounting groove 10 of the bus and mounted, the battery of the bus 2 is automatically replaced. .

  FIG. 7 is a front view of FIG. 1 according to the second embodiment of the present invention, FIG. 8 is an internal configuration diagram showing the configuration and operational relationship of the automatic battery replacement system according to the second embodiment of the present invention, and FIG. FIG. 10 is an enlarged perspective view showing only the loading table of FIG. 8, and FIG. 10 is a partially enlarged perspective view of FIG.

  Referring to FIGS. 7 to 10, the automatic battery exchange system according to the second embodiment of the present invention is equally applied to the bus stop (or a specific battery exchange) shown in FIGS. . That is, in such a bus platform, the elevating frame 100 in which the horizontal frame 120 and the vertical frame 110 have a substantially letter shape is installed.

  In the second embodiment of the present invention, the vertical frame 110 is formed with a stacking base 300 having multi-layered and multi-row stacking space portions 310 and 320 in the vertical direction. 320 are each provided with a battery support 250 that is slid and transferred in the horizontal direction to the loading space of another horizontal row.

  Here, it is not necessary to limit the number of layers of the loading space portions 310 and 320, but it is preferable that the horizontal rows are constituted by three rows. The reason is that the battery support bases 250 arranged in the left and right side loading space portions 320 are slid and transferred to the central row loading space portion 310 with the loading space portion 310 in the middle row as a reference.

  That is, of the stacking space portions 310 and 320 that are multi-layered and have three rows in the horizontal direction, no separate battery support is disposed in the stacking space portion 310 in the center row, and only the loading space portions 320 in the left and right side rows are provided. By arranging the battery support bases 250 in the horizontal direction, the battery support bases 250 arranged in the left and right side stacking space portions 320 are horizontally moved to the stacking space portion 310 in the central row by an electrical signal. It is to make it.

  Here, each of the stacking space portions 310 and 320 has a vertically penetrating shape, but the stacking space portion 310 in the center row always has a vertically penetrating shape, and the loading space portion 320 in the left and right side rows has penetrated. It does not matter if it consists of a form or a shielded form.

  In addition, the battery support base 250 on which the battery B is mounted and which is disposed in the stacking space 320 and slides horizontally has a structure in which a through hole 252 is formed in the central portion.

  On the other hand, the battery B mounted on the battery support 250 located in any stacking space portion of the central row is lifted or lowered while vertically moving above the stacking space portion 310 of the central row in the stacking table 300. A lifting bar 350 is provided.

  In addition, among the loading space portions 320 in the left and right side rows of the loading table 300, a battery support with a fully charged battery mounted on one side of the lowermost row on either side is an empty loading space of the loading table 300. A storage space 340 is formed to supply the battery 320 to the unit 320 or to collect a battery support on which a battery on which a discharge battery is mounted is mounted.

  In the second embodiment of the present invention configured as described above, the loading space portions 310 and 320, the storage space portion 340, and the lifting bar 350 in the loading table 300 are circuit-connected to the above-described control portion and follow an electrical signal. When the operation is applied, the battery support base 250 arranged in each of the stacking space portions 310 and 320 is moved in the horizontal direction, the battery support base 250 is horizontally moved in the storage space portion 340 and the stacking space portions 310 and 320, and the lifting / lowering rod 350 is moved. A detailed description of this will be described later.

  On the other hand, a pair of fixed guide rails 210 arranged in the horizontal direction are installed on the upper front side and the rear upper side of the horizontal frame 120, respectively, and the variable guide rails 220 that horizontally move along the fixed guide rails 210. Is installed.

  The variable guide rail 220 is provided with a moving rail 230 that is vertically installed and moved up and down with respect to the variable guide rail 220 and horizontally moves along the variable guide rail 220. A gripping means 240 for gripping the battery is installed at the lower end of the moving rail 230.

  Here, the variable guide rail 220, the moving rail 230, and the gripping means 240 may be provided in only one set, but the pickup of the discharge battery mounted in the battery mounting groove 10 of the bus 2 and the loading table 300 are also included. Preferably, the process of picking up a fully charged battery is performed in two sets side by side so that they are alternately performed.

  In the drawing, an unexplained symbol 200 is used to refer to the fixed guide rail 210, the variable guide rail 220, the moving rail 230, and the gripping means 240, and indicates a battery replacement system.

  For reference, in the second embodiment of the present invention, the fixed guide rails 210 are installed in pairs in the horizontal direction on the front upper side and the rear upper side of the horizontal frame 120, and the variable guide rail 220 is connected to the fixed guide rail 210. As an example, the fixed guide rails 210 are installed side by side above the left and right surfaces of the horizontal frame 120, and the variable guide rails 220 are fixed guide rails 210. Of course, it can also be installed laterally.

  In the second embodiment of the present invention, the vertical frame 110, the fixed guide rail 210, the variable guide rail 220, and the moving rail 230 provided with the loading table 300 on which a plurality of battery support platforms 250 are loaded are designated. Although the bus 2 that enters the landing is variable, and particularly precise position control is impossible, the gripping means 240 of the moving rail 230 is set to the position of the bus by the absolute position that is set. It is very difficult to always be on the same vertical line as the battery seated in the mounting groove.

  In other words, the bus can stop at the set position along the guide stop line and be positioned in the position area for battery replacement, but the set position (the gripping means 240 of any one moving rail 230 can be Therefore, it is important that the moving rail 230 finds the position of the battery mounted in the battery mounting groove 10 of the bus 2 and aligns it on the same vertical line.

  Here, also in the second embodiment of the present invention, as shown in FIG. 11, the difference in the position of the battery mounted in the battery mounting groove 10 of the bus grasping means 240 and the bus rail 230 is detected using the image recognition device. Then, by transferring the position correction data to the control unit, an accurate position on the same line is detected, and the gripping means 240 of the moving rail 230 is positioned on the same vertical line as the bus battery. Since the operation of the image recognition apparatus according to the second embodiment of the present invention is substantially the same as that of the first embodiment described above, a duplicate description is omitted.

  The operational relationship of the electric vehicle battery automatic replacement system according to the second embodiment of the present invention configured as described above will be described as follows.

  First, in a state where the fully charged battery or the fully charged battery and the discharge battery are respectively attached to the battery support base 250 in the loading base 300 of the vertical frame 110, that is, the loading space portion 320 in the left and right side rows of the loading base 300. When the vehicle enters the platform and inputs a signal for battery replacement, the discharge battery is replaced with a fully charged battery.

  That is, after the bus 2 enters the landing and stops along the stop line, a battery replacement signal is input, and the open / close cover 12 of the battery mounting groove 10 is opened to activate the image recognition device and the control unit. Then, after performing the position correction of any one of the moving rails 230, the gripping means 240 installed at the lower end thereof moves on the same vertical line as the battery mounted in the mounting groove 10 of the bus. This process will be described in detail as follows.

  When the bus 2 enters the landing and stops along the stop line, and the opening / closing cover 12 of the battery mounting groove 10 is opened, the battery mounted in the battery mounting groove 10 is held by any one of the moving rails 230. When the image recognition apparatus comes to be located on the same vertical line close to 240, the image recognition apparatus sends it to the control unit to correct the position of the moving rail 230.

  That is, if an image in which the position of the battery mounting groove 10 taken by the CCD camera is not located on the same vertical line as the gripping means 240 of the moving rail 230 is taken and transmitted to the video information processing unit, the taken position and the current moving rail The gripping means 240 of 230 is located, the coordinate value of the absolute position is calculated by the calculation unit and transmitted to the control unit, and the control unit corrects the variable guide rail 220 and the moving rail 230 by the driving unit by the transmitted coordinate value. By applying the operation signal so as to move to a different position, the battery mounted in the battery mounting groove 10 of the bus and the gripping means 240 of the moving rail 230 are corrected so as to be located on the same vertical line.

  That is, any one of the variable guide rails 220 moves in the X-axis or Y-axis direction along the pair of fixed guide rails 210 by the application of the drive signal of the driving means by the control unit, and moves along the variable guide rails 220. As the rail 230 moves in the Y-axis or X-axis direction, the gripping means 240 installed at the lower end of the moving rail 230 moves to a position that coincides with the battery mounting groove 10 of the bus, thereby correcting the position.

  As described above, when the variable guide rail 220 and the moving rail 230 move and the gripping means 240 of the moving rail 230 is positioned on the same vertical line as the battery mounted in the battery mounting groove 10 of the bus, the moving rail After the gripping means 240 of 230 is lowered and lifted while gripping the battery, the gripping means 240 moves horizontally in the X axis and Y axis above the lifting bar 350 of the stacking table 300.

  On the other hand, of the variable guide rails 220, the other variable guide rail moves horizontally to the X axis and the Y axis, picks up a fully charged battery that is lifted and lowered by the lifting bar 350 of the loading table 300, and then the battery of the bus 2. It moves horizontally along the X axis and the Y axis so as to be on the same vertical line as the mounting groove 10.

  Therefore, the gripping means and the moving rail for gripping the discharge battery are lowered to the Z-axis and the discharge battery is seated on the lifting bar 350 of the loading table 300, and the gripping means and the movement for gripping the fully charged battery The rail is also lowered to the Z axis so that the fully charged battery is seated in the battery mounting groove 10 of the bus 2 so that the discharge battery and the fully charged battery are exchanged.

  Here, the transfer process of the fully charged battery in the loading table 300 will be briefly described as follows.

  The battery support base 250 located in a selected loading space portion among the loading space portions 320 in the left and right side rows of the loading table 300 is moved horizontally by the electrical signal and positioned in the loading space portion 310 in the center row. If the elevating bar 350 is raised in this state, only the fully charged battery is centered while the elevating bar 350 passes through the portion where the stacking space portion 310 of the central row penetrates and the through hole 252 of the battery support base 250. It is raised to the upper part of the stacking space portion 310 of the row.

  In this state, the fully charged battery is supplied by one of the moving rail gripping means, and the discharge battery is recovered by the other moving rail gripping means. At this time, if the discharge battery is seated on the lifting / lowering rod 250, it is lowered by the electrical signal and seated on the battery support 250 from which the fully charged battery has been removed. What is necessary is just to move horizontally from the loading space part 310 of a row | line | column to the loading space part 320 of the original left-right side row | line | column.

  Here, the horizontal movement of the battery support base 250 from the left and right side stacking space portions 320 to the central row stacking space portion 310 is conventionally performed by driving means such as rollers and timing belts, pushes by cylinders, and the like. Although any known configuration can be implemented, a detailed description thereof will be omitted.

  On the other hand, in the state where the discharge batteries are mounted in the left and right side stacking space portions 320 of the loading table 300, the battery support table 250 on which the discharge batteries are mounted is moved horizontally by the electrical signal from the control unit, and is moved up and down. What is necessary is just to raise / lower with the stick | rod 350, to send to the storage space part 340, to receive the supply of a fully charged battery in the storage space part 340, and to move to the stacking space part 320 of the said right-and-left side row | line | column.

  Here, in a state where the discharge battery is mounted on the loading space portion 320 of the loading table 300, the discharge battery is positioned above the loading space portion 310 in the central row by horizontally moving the battery support base 250 and raising the lifting bar 350. Alternatively, this can be replaced with a fully charged battery, and the fully charged battery can be mounted in the loading space 320 in the left and right side rows of the loading table 300.
