Abstract

This invention discloses a swing brush plate assembly, a power-collecting assembly, and a shuttle system. The swing brush plate assembly is used in conjunction with a charging brush block assembly disposed on a device to be charged. The swing brush plate assembly includes a swing brush plate and a first electrode. The swing brush plate is rotatably mounted on an external structure about a first axis. The first electrode is disposed on the swing brush plate and can be electrically connected to an external power supply device. The swing brush plate can rotate to a charging position where the first electrode directly contacts the charging brush block assembly or to a position that avoids the charging brush block assembly. The first electrode of this swing brush plate assembly can directly contact the charging brush block assembly for charging. Friction is low during the contact process, making it less likely to damage the first electrode. Furthermore, because the swing brush plate can rotate to a position that avoids the charging brush assembly, the swing brush plate assembly will not affect the movement of the device to be charged when charging is not required, and the friction between the charging brush block assembly and the swing brush plate assembly is minimal when the charging brush block assembly passes through the swing brush plate assembly.

Description

Technical Field

[0001] This invention relates to the field of shuttle charging technology, and more particularly to a swing brush assembly, a power collection assembly, and a shuttle system. Background Technology

[0002] Currently, there are two main methods for powering the shuttle: one is real-time power supply via a sliding contact line, and the other is supercapacitor power supply. Supercapacitors include lithium capacitors and pure capacitors. Both lithium capacitors and pure capacitors require charging before use. Lithium capacitors charge slowly but have a long service life, while pure capacitors charge quickly but discharge quickly, resulting in a short service life. The supercapacitor charging method involves placing a charging brush block on each side of the shuttle and a charging brush plate on the shelf track. The shuttle needs to travel to the charging position for charging. During this process, the charging brush block and the charging brush plate make rigid contact in the direction of travel and gradually align, so that they are in contact and adhere to each other in the direction perpendicular to the travel direction, thus enabling charging.

[0003] Because the shuttle requires frequent charging, this charging method necessitates frequent contact between the charging brush plate and the charging brush block. However, during the contact process, the rigid contact between the charging brush plate and the charging brush block inevitably leads to collisions and dry friction, making them prone to damage and resulting in a short lifespan. Furthermore, the shuttle has layer-changing requirements, so friction also occurs between the charging brush plate and the charging brush block as they pass through the charging brush plate to the end of the guide rail, potentially damaging the electrode plates. Summary of the Invention

[0004] The first objective of this invention is to provide a swing brush assembly that can be used in conjunction with a charging brush block assembly, and that the friction between the two is small during use, making it less prone to damage and with a long service life.

[0005] A swing brush plate assembly is provided for use in conjunction with a charging brush block assembly disposed on a device to be charged. The swing brush plate assembly includes: a swing brush plate, which is rotatably disposed on an external structure about a first axis; and a first electrode disposed on the swing brush plate, which is electrically connected to an external power supply device. The swing brush plate is rotatable to a charging position where the first electrode is directly in contact with the charging brush block assembly or to a position that avoids the charging brush block assembly.

[0007] Preferably, the oscillating brush plate includes a rotating shaft seat, a first mounting plate, and a second mounting plate. The rotating shaft seat is rotatably connected to the brush plate rotating shaft. The first mounting plate and the second mounting plate protrude from the side wall of the rotating shaft seat and are arranged at a 90° angle. The first electrode is disposed on the first mounting plate. The charging brush block assembly, moving forward along the guide rail, can push the first mounting plate to rotate the first electrode from the charging position to the clearance position. The charging brush block assembly, moving backward along the guide rail, can push the second mounting plate to rotate the first electrode from the clearance position to the charging position.

[0008] Preferably, a positioning groove is formed on the first end face of the rotating shaft seat. The positioning groove includes two adjacent spiral grooves and a separating ridge between the two spiral grooves. The central angle of the positioning groove is 90°. The bottom surface of each spiral groove is a spiral inclined surface, and the height of the spiral inclined surface near the separating ridge is greater than the height of the side away from the separating ridge. The oscillating brush plate assembly also includes a positioning protrusion, which includes a ball and an elastic element. One end of the elastic element is connected to the ball, and the other end of the elastic element is fixed relative to the guide rail. The ball is placed in the positioning groove and can move across the separating ridge on the two spiral inclined surfaces.

[0009] Preferably, the first electrode is fixedly connected to the first mounting plate via a conductive connector; the oscillating brush assembly further includes a brush cable, one end of which is conductively connected to the conductive connector, and the other end of which is electrically connected to the external power supply device.

[0010] Preferably, a cable receiving groove is formed on the second end face of the rotating shaft seat, and a cable movable groove is formed on the side wall of the rotating shaft seat. The cable movable groove is connected to the cable receiving groove, the middle part of the brush plate cable is placed in the cable receiving groove, and the other end of the brush plate cable passes through the cable movable groove.

[0011] The second objective of this invention is to provide a power-gathering component that is not easily damaged and has a long service life.

The fixed brush block is fixedly disposed on the device to be charged, and the second electrode is disposed on the fixed brush block. The second electrode is electrically connected to the energy storage device of the device to be charged and is used to abut against the first electrode.

[0014] Preferably, the fixed brush block is provided with a mounting cavity, and the second electrode is disposed in the mounting cavity; the charging brush block assembly further includes an elastomer, the elastomer is placed in the mounting cavity, one end of the elastomer is connected to the second electrode, and the other end of the elastomer abuts against the inner wall surface of the mounting cavity.

[0015] Preferably, the electrode surface on the second electrode that is in contact with the first electrode is perpendicular to the direction of movement of the device to be charged.

[0016] A third objective of this invention is to provide a shuttle system whose power-collecting components have a long service life.

[0017] To achieve this objective, the present invention adopts the following technical solution:

[0018] A shuttle system includes a shuttle, a guide rail, and the aforementioned power collection components, wherein the shuttle is a device to be charged and is movably mounted on the guide rail.

[0019] The beneficial effects of this invention are:

[0020] The present invention provides a swing brush plate assembly for use in conjunction with a charging brush block assembly disposed on a device to be charged. The swing brush plate assembly includes a swing brush plate and a first electrode. The swing brush plate is rotatably mounted on an external structure around a first axis. The first electrode is disposed on the swing brush plate and can be electrically connected to an external power supply device. The swing brush plate can rotate to a charging position where the first electrode directly contacts the charging brush block assembly or to a position that avoids the charging brush block assembly. The first electrode of this swing brush plate assembly can directly contact the charging brush block assembly for charging. Friction is minimal during the contact process, making it less likely to damage the first electrode. Furthermore, because the swing brush plate can rotate to a position that avoids the charging brush assembly, it does not affect the movement of the device to be charged when charging is not required, and the friction between the charging brush block assembly and the swing brush plate assembly is minimal when the latter passes by.

Detailed Implementation

[0047] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0050] like Figure 1 , Figure 3 and Figure 4 As shown, the present invention provides a power-harvesting component 100, which enables an electrical connection between an external power supply device and a movable device to be charged, thereby providing electrical energy to the energy storage device of the device to be charged. In some embodiments, the power-harvesting component 100 is used in a shuttle system, and the device to be charged is the shuttle 1. Of course, in other embodiments, the device to be charged is not limited to the shuttle 1, and can be any device that has a charging requirement and needs to be moved. For ease of explanation, the following description uses the shuttle 1 as the device to be charged as an example. The shuttle 1 is movably mounted on the guide rail 2.

[0051] like Figures 1 to 18 As shown, the power extraction assembly 100 includes a charging brush block assembly 110 and a swing brush plate assembly 120. The charging brush block assembly 110 includes a fixed brush block 111 and a second electrode 112. The fixed brush block 111 is fixedly mounted on the shuttle 1, and the second electrode 112 is mounted on the fixed brush block 111. The second electrode 112 can be electrically connected to the energy storage device of the shuttle 1 through a brush block cable 113. In some embodiments, the energy storage device is a supercapacitor; in some specific embodiments, the energy storage device is a lithium capacitor or a pure capacitor.

[0052] The oscillating brush plate assembly 120 includes an oscillating brush plate 121 and a first electrode 122. The oscillating brush plate 121 is rotatably mounted on the guide rail 2, and the first electrode 122 is mounted on the oscillating brush plate 121. The first electrode 122 can be electrically connected to an external power supply device. The external power supply device can be AC ​​power or an external portable power source. The oscillating brush plate 121 can rotate to a charging position where the first electrode 122 and the second electrode 112 are directly in contact, or to a position that avoids the charging brush block assembly 110. It should be noted that in the initial state, the first electrode 122 and the second electrode 112 are arranged parallel to each other. This initial state refers to the state when the shuttle 1 is picking up and placing goods on the guide rail 2. In this state, the shuttle 1 does not have a charging requirement or a layer-changing requirement.

[0053] When the shuttle 1 does not need charging, the charging brush block assembly 110 is separated from the oscillating brush plate assembly 120. When the shuttle 1 needs charging, the shuttle 1 moves along the guide rail 2 toward the charging position where the oscillating brush plate assembly 120 is located. During this process, the charging brush block assembly 110 moves with the shuttle 1 toward the oscillating brush plate assembly 120. As the charging brush block assembly 110 continues to move, the parallel second electrode 112 and the first electrode 122 gradually approach and directly contact each other (e.g., ...). Figure 19 As shown in the diagram, after the second electrode 112 and the first electrode 122 are in contact, the power storage device of the shuttle 1 can draw power from the external power supply device through the power taking component 100. When the shuttle 1 needs to change layers, the swing brush plate assembly 120 can rotate to a position to avoid the charging brush block assembly 110 (as shown in the diagram). Figure 20 (As shown in the state), the shuttle 1 can move through the charging position to the layer-changing elevator 6 set at one end of the guide rail 2, and change layers with the help of the layer-changing elevator 6. During this process, there is no current flow between the first electrode 122 and the second electrode 112.

[0054] Compared to the collisions and significant dry friction caused by the horizontal sliding contact of charging components in existing technologies, the first electrode 122 of the power-collecting component 100 provided in this embodiment of the invention can directly contact and charge the second electrode 112. During the contact process, the friction and impact between the two electrodes are minimal, making them less prone to damage and extending their service life. Furthermore, since the swing brush plate 121 can rotate to an avoidance position, the swing brush plate assembly 120 will not affect the movement of the device to be charged on the guide rail 2 when there is no charging demand. Moreover, during the movement of the charging brush block assembly 110 towards the layer-changing elevator 6 via the swing brush plate assembly 120, the friction between the two electrodes is minimal, making them less prone to damage and further extending their service life.

[0055] It should be noted that the oscillating brush assembly 120 is a unit that can be manufactured and sold independently, and its manufacture and sale do not depend on the charging brush block assembly 110. Furthermore, the oscillating brush assembly 120 can be used with various charging brush block assemblies 110, and is not limited to the structure including the fixed brush block 111 and the second electrode 112. For example, the oscillating brush assembly 120 can be used with charging brush block assemblies 110 that only include the second electrode 112 or include more structures.

[0056] In some embodiments, the fixing brush block 111 is a block-shaped structure made of an insulating material, such as a nylon block made of nylon. In some specific embodiments, such as Figure 9As shown, the fixed brush block 111 includes an insulating base 1111 and an insulating block 1112. The insulating base 1111 is fixedly connected to the side wall of the shuttle 1, and the connection can be made by screws. The insulating block 1112 is vertically protruding on the side of the insulating base 1111 away from the shuttle 1, and the second electrode 112 is disposed on the insulating block 1112.

[0057] To mount the second electrode 112, a mounting cavity is provided on the fixed brush block 111. Specifically, the mounting cavity is located on the insulating block 1112, and the second electrode 112 is disposed within the mounting cavity. In some specific embodiments, the mounting cavity is a rectangular cavity, and the second electrode 112 is a rectangular sheet; in some more specific embodiments, the second electrode 112 is a copper sheet, which has good conductivity. Of course, in some other embodiments, the second electrode 112 can also be a structure of other shapes made of other conductive materials.

[0058] To reduce the impact force when the second electrode 112 contacts the first electrode 122, the charging brush assembly 110 further includes an elastomer (not shown in the figure). The elastomer is placed inside the mounting cavity, with one end connected to the second electrode 112 and the other end abutting against the inner wall of the mounting cavity. The elastomer allows the second electrode 112 to extend and retract, thereby reducing the impact force when the second electrode 112 contacts the first electrode 122. In some embodiments, the elastomer is a helical spring or a spring sheet.

[0059] To achieve the rotational connection of the oscillating brush plate 121 on the guide rail 2, continue referring to... Figure 10 As shown, the swing brush assembly 120 also includes a brush shaft 123, which is fixedly mounted on the guide rail 2, and the swing brush 121 is rotatably connected to the brush shaft 123.

[0060] In some embodiments, such as Figure 17 As shown, the brush plate rotating shaft 123 includes a fixed base 1231 and a rotating shaft part 1232 that is vertically protruding from the center of the fixed base 1231. The fixed base 1231 is fixedly connected to the guide rail 2. The connection method includes, but is not limited to, screw connection, welding or bonding. The rotating brush plate 121 has a rotating shaft hole in the middle, and the rotating shaft part 1232 passes through the rotating shaft hole.

[0061] Continue to refer to Figures 10 to 13As shown, the oscillating brush plate 121 includes a rotating shaft seat 1211, a first mounting plate 1212, and a second mounting plate 1213. A rotating shaft hole is provided on the rotating shaft seat 1211. The rotating shaft seat 1211 is rotatably connected to the brush plate rotating shaft 123. The rotating shaft seat 1211 is cylindrical. The first mounting plate 1212 and the second mounting plate 1213 protrude from the side wall of the rotating shaft seat 1211 and are set at a 90° angle. The first mounting plate 1212 and the second mounting plate 1213 are respectively arranged to extend radially along the rotating shaft seat 1211. The first electrode 122 is disposed on the first mounting plate 1212.

[0062] It should be noted that the guide rail 2 is divided into a first part and a second part with the charging position where the swing brush assembly 120 is located as the boundary. The first part is set close to the shelf 7 and the second part is set close to the layer changing elevator 6. The direction in which the shuttle 1 moves on the first part of the guide rail 2 toward the charging position is defined as forward movement, and the direction in which the shuttle 1 moves on the second part of the guide rail 2 toward the charging position is defined as reverse movement.

[0063] The power-collecting component 100, by providing two mounting plates arranged at a 90° angle on the oscillating brush plate 121, not only enables the fixed brush block 111, which moves forward with the shuttle 1 on the guide rail 2, to push the first mounting plate 1212, causing the first electrode 122 to rotate from the charging position to the avoidance position (e.g., ...). Figure 20 (As shown in the diagram), this allows the shuttle 1 to move forward via the swing brush assembly 120 towards the floor-changing elevator 6; and the fixed brush block 111, which moves in the opposite direction on the guide rail 2 with the shuttle 1, can push the second mounting plate 1213 to cause the swing brush 121 to rotate in the opposite direction, thereby rotating the swing brush 121 from the avoidance position to the charging position, and thus causing the shuttle 1 to move in the opposite direction via the swing brush assembly 120 towards the shelf 7. The entire process is achieved through mechanical contact, eliminating the need for additional power components and reducing operating costs.

[0064] In some embodiments, the electrode surface of the second electrode 112 that is in contact with the first electrode 122 is perpendicular to the direction of movement of the device to be charged. Of course, in other embodiments, other angles may also be used.

[0065] In some embodiments, the oscillating brush plate 121 is a block structure made of an insulating material, such as a nylon block made of nylon. Nylon has the advantages of insulation, wear resistance, and a certain degree of lubricity.

[0066] In order to install the first electrode 122, as Figure 12As shown, a receiving groove is provided on the first mounting plate 1212, and the first electrode 122 is disposed in the receiving groove and connected by a fixing connector 129. In some embodiments, the fixing connector 129 is a short screw; in some embodiments, the number of short screws is multiple, such as two, to improve the connection strength.

[0067] In some specific embodiments, the receiving groove is a rectangular cavity, and the first electrode 122 is a rectangular sheet; in some more specific embodiments, the first electrode 122 is a copper sheet, which has good electrical conductivity. Of course, in some other embodiments, the first electrode 122 can also be a structure of other shapes made of other conductive materials.

[0068] To achieve electrical connection between the first electrode 122 and the external power supply device, refer to... Figure 12 As shown, the first electrode 122 is fixedly connected to the first mounting plate 1212 via a conductive connector 128. The oscillating brush assembly 120 also includes a brush cable 127. One end of the brush cable 127 is electrically connected to the conductive connector 128, and the other end of the brush cable 127 is electrically connected to an external power supply device.

[0069] In some embodiments, the conductive connector 128 is a long screw made of conductive material, specifically a long countersunk screw. The long screw passes through the first electrode 122 and is located within the cavity of the first mounting plate 1212, with the long screw positioned between two short screws. Figure 12 and Figure 18 As shown, one end of the brush plate cable 127 is provided with a cable clamp 1271, which is clamped onto a long screw and locked by a copper nut 1210 and a copper washer 1216 fitted on the long screw.

[0070] Continue to refer to Figure 12 As shown, a cable receiving groove 1215 is formed on the upper end surface of the rotating shaft seat 1211, and a cable movable groove 1214 is formed on the side wall of the rotating shaft seat 1211. The cable movable groove 1214 communicates with the cable receiving groove 1215. The middle part of the brush plate cable 127 is placed in the cable receiving groove 1215, and the other end of the brush plate cable 127 passes through the cable movable groove 1214. The cable movable groove 1214 can prevent the brush plate cable 127 from being pulled and worn during the rotation of the swing brush plate 121.

[0071] In some embodiments, the cable tray 1215 is an annular tray, and the middle part of the brush plate cable 127 can be bent into an arc shape to be placed in the annular tray. In some embodiments, the cable movable tray 1214 is an arc-shaped tray with a central angle of not less than 90°.

[0072] To protect the cable and prevent foreign objects from entering the cable tray 1215, such as Figure 10 and Figure 11As shown, a pressure cap 125 is also provided on the upper end surface of the rotating shaft seat 1211. The pressure cap 125 is fixed to the middle protrusion of the rotating shaft seat 1211 by a locking screw 126.

[0073] To protect the brush plate cable 127, continue to refer to... Figure 5 As shown, a guard coil 8 is provided on the guide rail 2, and the other end of the brush plate cable 127 passes through the guard coil 8.

[0074] To limit the rotation angle of the oscillating brush plate 121 so that the rotating brush plate can smoothly oscillate and rotate 90° back and forth, continue referring to... Figures 13 to 17 As shown, a fan-shaped positioning groove is formed on the first end face of the pivot seat 1211. The positioning groove includes two adjacent spiral grooves 1217 and a separating ridge 1218 located between the two spiral grooves 1217. The central angle corresponding to the positioning groove is 90°, that is, the included angle between two positions on the outer side surfaces 12172 of the two spiral grooves 1217 is 90°. The bottom surface of each spiral groove 1217 is a spiral inclined surface 12171, and the height of the spiral inclined surface 12171 near the separating ridge 1218 is greater than the height of the side away from the separating ridge 1218. That is, the spiral directions of the two spiral grooves 1217 are opposite; if one is clockwise, the other is counterclockwise. In other words, the two spiral grooves 1217 are fan-shaped grooves formed by cutting downwards along two spiral lines, one clockwise and one counterclockwise.

[0075] The oscillating brush assembly 120 also includes a positioning protrusion 124, which includes a ball 1241 and an elastic element. One end of the elastic element is connected to the ball 1241, and the other end of the elastic element is fixed relative to the guide rail 2. The ball 1241 is placed in the positioning groove and can move across the separating protrusion 1218 on the two helical inclined surfaces 12171. In some embodiments, the positioning protrusion 124 is an adjustable positioning ball, which is a standard product, and the elastic element is a spring. Its specific structure will not be described in detail here.

[0076] like Figure 16 The diagram illustrates the working principle of the oscillating brush plate 121 and the adjustable positioning bead. In the charging state and after the first electrode 122 has rotated 90°, the ball 1241 of the adjustable positioning bead is in the state shown in the diagram, meaning the ball head of the ball 1241 is engaged at the deepest edge of the spiral groove 1217. At this point, the ball head restricts the position of the oscillating brush plate 121, preventing it from oscillating further. Furthermore, the nut 1242 at the tail of the adjustable positioning bead is adjustable, thereby adjusting the pressure of the elastic element to ensure the ball head has sufficient elastic force to restrict the position of the oscillating brush plate 121. Ultimately, this ensures that the oscillating brush plate 121 will not rotate when the two electrodes are in contact during the charging state.

[0077] Only when the shuttle 1 needs to pass through the charging station to change floors to the elevator 6, the powerful driving force of the shuttle 1 exceeds the limiting capacity of the ball head on the swing brush plate 121, allowing the swing brush plate 121 to complete its rotation. Furthermore, when the fixed brush block 111 on the shuttle 1 drives the swing brush plate 121 to rotate, the two disengage before the rotation angle reaches 90°. Therefore, the remaining 90° rotation is achieved by the elastic force of the ball head. The upward force of the ball head, along the tangential component of the spiral groove 1217, forces the swing brush plate 121 to continue rotating until it reaches the desired rotation angle. Figure 16 The state shown is as follows. It should be noted that when the fixed brush block 111 drives the swing brush plate 121 to rotate, the separating ridge 1218 has already passed the ball head. That is to say, before the fixed brush block 111 and the swing brush plate 121 separate, the ball head has entered the other spiral groove 1217 from one side spiral groove 1217 through the separating ridge 1218.

[0078] like Figure 21 As shown, the present invention also provides a shuttle system, which includes a shuttle 1, a guide rail 2 and the aforementioned power collection component 100. The shuttle 1 is a device to be charged and is movably mounted on the guide rail 2.

[0079] In some embodiments, such as Figure 1 As shown, the power supply component 100 is provided in two sets, namely, the shuttle system includes two swing brush plate components 120 and two charging brush block components 110. The two swing brush plate components 120 are respectively set on two guide rails 2 located on both sides of the aisle of the shelf 7, and the two charging brush block components 110 are respectively connected to the two sides of the shuttle 1 perpendicular to the direction of movement. The two swing brush plate components 120 and the two charging brush block components 110 are set in a one-to-one correspondence.

[0080] In some embodiments, continue to refer to Figure 21 As shown, the swing brush assembly 120 is arranged on one side of the buffer position 3 of the shuttle system. Since the cargo elevator 5 and the floor-changing elevator 6 of the shuttle system are also arranged on one side of the buffer position 3, arranging the swing brush assembly 120 on the same side of the buffer position 3 of the shuttle system facilitates wiring and can significantly reduce the length of the cables required for wiring. On the other hand, it improves charging efficiency. Whether the shuttle 1 is entering or leaving the warehouse, it needs to pick up or put down boxes 4 at the buffer position 3. The time spent picking up or putting down boxes 4 can be used for charging, which improves the working efficiency of the shuttle 1.

[0081] Additionally, it should be noted that, as Figure 21As shown, the power extraction component 100 provided in this embodiment of the invention can also be used normally when there is a floor-changing elevator 6. The charging brush block component 110 on the shuttle 11 can enter the floor-changing elevator 6 after passing through the swing brush plate component 120 set on the guide rail 2.

[0082] Furthermore, it should be noted that the second electrode 112 and the first electrode 122 of the present invention are in surface contact, rather than point contact on a spherical surface or line contact on a cylindrical surface of a roller. Since the charging current is very large, if there is no point contact or line contact, arcing will occur, i.e., sparks will be generated, while surface contact will not cause arcing.

[0083] The shuttle system works as follows:

[0084] When the shuttle 1 needs to be charged, the shuttle 1 moves along the guide rail 2 until the second electrode 112 of the swing brush plate assembly 120 is directly attached to the first electrode 122 of the charging brush block assembly 110. Since the second electrode 112 and the first electrode 122 are in direct surface contact and the second electrode 112 is retractable, the friction and impact between the two are reduced, and the service life of the power taking component 100 is improved.

[0085] When the shuttle 1 needs to enter the floor-changing elevator 6 for floor changing, the external power supply device stops supplying power. The shuttle 1 moves along the guide rail 2 to the charging position and continues to move forward. Under the strong driving force of the shuttle 1, the fixed brush block 111 and the second electrode 112 set on it push the first electrode 122 and the first mounting plate 1212 to make the swing brush plate 121 rotate around the brush plate rotating shaft 123. Under the cooperation of the adjustable positioning bead and the positioning groove, the swing brush plate 121 can rotate 90° clockwise and then stop rotating. At this time, the swing brush plate 121 has rotated to the avoidance position to avoid the charging brush block assembly 110.

[0086] When the shuttle 1 reaches the target layer of the shelf 7 or returns to the original layer, the external power supply device stops supplying power. The shuttle 1 moves in the opposite direction on the guide rail 2 and continues to move forward after reaching the charging position again. Under the strong driving force of the shuttle 1, the side of the fixed brush block 111 without the second electrode 112 pushes the second mounting plate 1213 (at this time, the second mounting plate 1213 has rotated to the original position of the first mounting plate 1212) to make the swing brush plate 121 rotate in the opposite direction around the brush plate pivot 123. With the cooperation of the adjustable positioning bead and the positioning groove, the swing brush plate 121 can rotate 90° counterclockwise and then stop rotating. At this time, the swing brush plate 121 has rotated to the charging position so that the first electrode 122 and the second electrode 112 can be attached for the next charging.

[0087] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
