[0001] This application was filed on December 31, 2020, with application number 202011629823.2, and titled [Title Missing].

[0002] Divisional case of the Chinese invention patent for "Battery storage components and battery swapping stations or energy storage stations including the same". Technical Field

[0003] This invention relates to the field of battery swapping, and in particular to a battery storage component and a battery swapping station or energy storage station including the component. Background Technology

[0004] Currently, Chinese patent application CN104773139A discloses a stacking device and a battery swapping device. By setting up a stacking walking mechanism, a lifting mechanism and a fork mechanism in cooperation, it can perform the picking and placing of objects. Moreover, the lifting mechanism includes lifting guide wheels that are rotatably connected to the pallet assembly and rolled in the frame. These guide wheels play a supporting and guiding role during the lifting and lowering of the pallet assembly, which can improve the stability of the lifting and lowering. At the same time, the frame can drive the lifting mechanism and the pallet assembly to move horizontally, so that the pallet assembly can move along the X and Y directions to the battery compartments at multiple positions on the battery rack.

[0005] This type of battery swapping equipment has many degrees of freedom of movement and many moving parts, resulting in poor equipment reliability and high manufacturing and maintenance costs. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the existing battery swapping equipment, which has a complex structure and many degrees of freedom of movement, resulting in poor reliability, and to provide a battery storage component and a battery swapping station or energy storage station containing the component.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] A battery storage assembly includes two battery racks located on both sides and a lifting and transferring device located between the two rows of battery racks, wherein each battery rack has at least two inner columns adjacent to the lifting and transferring device, and the lifting and transferring device moves up and down along the inner columns.

[0009] The lifting and transfer device of this battery storage assembly stores and retrieves batteries relative to each battery rack by lifting and moving them, eliminating the need for horizontal movement. This saves space occupied by the entire battery storage assembly and is highly efficient. At the same time, the lifting and transfer device uses the inner columns on the battery rack as guide columns to achieve lifting and moving relative to the battery rack, effectively simplifying the overall structure of the battery storage assembly. By reducing the degree of freedom in handling batteries, the overall reliability is improved, and the structure is also more compact.

[0010] Preferably, the lifting and transferring device includes a battery picking and placing mechanism, a transmission mechanism, and a guiding mechanism. The transmission mechanism is disposed between the battery picking and placing mechanism and the inner column. The inner column has a guide surface that cooperates with the guiding mechanism. The guiding mechanism is disposed between the battery picking and placing mechanism and the guide surface, so that the transmission mechanism drives the battery picking and placing mechanism to move up and down along the guiding mechanism to transfer the battery.

[0011] By setting up a transmission mechanism, the battery picking and placing mechanism can be driven to move up and down along the inner column of the battery rack. In conjunction with the guide mechanism, the accuracy of the movement of the battery picking and placing mechanism relative to the battery rack and the reliability of its position are improved, ensuring that batteries can be accurately picked up and placed from each layer of the battery rack.

[0012] Preferably, the guiding mechanism includes a roller assembly connected to the battery pick-and-place mechanism, the rolling surface of the roller assembly abutting against the guide surface of the inner column and being rotatably disposed relative to the guide surface.

[0013] This guiding mechanism moves and guides relative to the guide surface by relative rolling, resulting in smoother and more reliable movement with less noise.

[0014] Preferably, the guiding mechanism includes a sliding component, the sliding component comprising:

[0015] A slide rail is disposed on the guide surface of the inner column;

[0016] A slider is connected to the battery loading and unloading mechanism, and the slider is positioned on the slide rail and slidably disposed relative to the slide rail.

[0017] This guiding mechanism moves and guides relative to the guide surface through relative sliding, resulting in a simpler structure and better reliability. Furthermore, it requires fewer components compared to other guiding methods, thus reducing costs.

[0018] Preferably, the transmission mechanism includes a chain and two sprockets. The sprockets are fixed to the inner column, and the two ends of the chain are respectively connected to the upper and lower edges of the side of the battery pick-and-place mechanism along the vertical direction. The chain and the side of the battery pick-and-place mechanism together form a ring, and the sprockets are sequentially meshed and sleeved on each other. Rotation of any one of the sprockets causes the chain to move, thereby driving the battery pick-and-place mechanism to move up and down along the guide mechanism.

[0019] This transmission mechanism uses sprockets and chains to drive the battery loading and unloading mechanism to move up and down relative to the battery rack. It has high structural strength and good reliability.

[0020] Preferably, the transmission mechanism includes a drive wheel, a driven wheel, and a timing belt. One end of the timing belt is fixedly connected to one end of the battery pick-and-place mechanism, and then the drive wheel and the driven wheel are sequentially meshed and sleeved on it. The belt is then fixedly connected to the other end of the battery pick-and-place mechanism. The driven wheel presses the timing belt onto the inner column. The rotation of the drive wheel causes the timing belt to move, thereby driving the battery pick-and-place mechanism to move up and down along the guide mechanism.

[0021] This transmission mechanism, which uses a synchronous belt for power transmission, has a lightweight structure and is easy to maintain.

[0022] Preferably, the transmission mechanism includes a rack and a gear that mesh with each other. The gear is pivotally connected to the battery pick-and-place mechanism. The rack is vertically disposed on the inner column. The inner column has a C-shaped cross-section, with an opening facing the battery pick-and-place mechanism or the battery and an inner cavity for accommodating the gear. The inner cavity has a first wall, a second wall adjacent to the first wall, and a third wall opposite to the first wall. The rack is disposed on the first or third wall of the inner cavity. The gear meshes with the rack. The gear rotates to drive the battery pick-and-place mechanism to move up and down along the guide mechanism.

[0023] This transmission mechanism uses gears and racks for power transmission, enabling the battery loading and unloading mechanism to move up and down along the guide mechanism where the rack is located. Furthermore, the gears and rack themselves have a certain meshing capacity, allowing them to withstand a certain amount of gravity. Moreover, the maximum movable distance of the battery loading and unloading mechanism relative to the battery holder can be extended by lengthening the rack, facilitating adjustments to the stroke of the mechanism and providing good expandability.

[0024] Preferably, the transmission mechanism includes a drum, a traction rope, and a guide wheel. One end of the traction rope is connected to the battery pick-and-place mechanism. After being connected to the guide wheel, the other end of the traction rope is connected to the drum. The traction rope is wound around the drum as the drum rotates, so that the battery pick-and-place mechanism moves up and down along the guide mechanism.

[0025] This transmission mechanism uses a traction rope wound around a drum to drive the lifting and lowering movement of the battery pick-and-place mechanism. This transmission method is simple; the lifting and lowering movement of the battery pick-and-place mechanism can be controlled by controlling the number of turns the rope is wound around the drum. In addition, it is also easy to extend in the vertical direction by increasing the length of the traction rope and the height of the battery rack column. The direction of the forward extension can be changed by the guide wheel, and the traction rope can be connected vertically to the battery pick-and-place mechanism, so that the driving force on the battery pick-and-place mechanism is also in the vertical direction, which can make the transmission smooth.

[0026] Preferably, the transmission mechanism includes a traction sheave, a counterweight block, and a counterweight cable. The counterweight cable is sleeved on the traction sheave, and both ends of the counterweight cable are connected to the counterweight block and the battery loading / unloading mechanism, respectively. The traction sheave drives the counterweight cable to move through friction, so that the battery loading / unloading mechanism moves up and down along the guide mechanism.

[0027] This transmission mechanism drives the lifting and lowering movement of the battery pick-and-place mechanism through the transmission of the counterweight, traction wheel, and counterweight cable. This transmission method is simple, and the lifting and lowering movement of the battery pick-and-place mechanism can be controlled by controlling the lifting and lowering of the counterweight. In addition, it is also easy to expand in the height direction by increasing the length of the counterweight cable and the height of the battery rack column.

[0028] Preferably, the battery storage assembly further includes a counterweight mechanism, which includes a counterweight block, a counterweight cable, and a pulley. One end of the counterweight cable is connected to the counterweight block, and the other end of the counterweight cable is connected to the lifting and transferring device. The pulley cooperates with the counterweight cable to guide the counterweight cable in a sliding manner.

[0029] This transmission mechanism, through the counterweight mechanism, can assist the transmission mechanism, reduce the load requirements of the transmission mechanism during operation, and also enable the lifting and transfer device to stop stably at a specific position of a battery rack.

[0030] A battery swapping station or energy storage station includes a battery storage area, wherein the battery storage area is provided with the battery storage components described above.

[0031] In this battery swapping station or energy storage station, the battery storage components located in the battery storage area access batteries relative to the battery racks on both sides by lifting and moving them, without the need for horizontal movement, saving space and increasing efficiency. At the same time, the lifting and transfer device uses the columns on the battery racks as guide columns to achieve lifting and moving relative to the battery racks, effectively simplifying the overall structure of the battery swapping station or energy storage station, making the structure more compact and more reliable.

[0032] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0033] The positive and progressive effects of this invention are as follows:

[0034] In this battery storage assembly and the battery swapping station or energy storage station containing it, the lifting and transfer device accesses batteries relative to each battery rack by lifting and moving them, eliminating the need for horizontal movement. This saves space occupied by the battery storage assembly in the battery swapping station or energy storage station, effectively reducing the footprint of the station or energy storage station. Simultaneously, the lifting and transfer device utilizes the inner columns on the battery racks as guide columns for lifting and moving relative to the battery racks, effectively simplifying the overall structure of the battery storage assembly. By reducing the degrees of freedom in handling batteries, it improves overall reliability and makes the structure more compact. Attached Figure Description

[0127] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0128] Example 1

[0129] This invention provides a battery storage assembly 1, which is installed in the battery storage area of ​​a battery swapping station or energy storage station. The battery storage assembly 1 is used for charging and transferring batteries of electric vehicles. Specifically, the battery storage assembly 1 includes a lifting and transferring device and two battery racks 2 located on both sides of the lifting and transferring device. The two battery racks 2 are respectively set against the lifting and transferring device. The lifting and transferring device is used to transfer batteries between multiple battery compartments 210 arranged vertically in the battery racks 2.

[0130] like Figure 8 As shown, battery compartments 210 are arranged sequentially from bottom to top on the battery rack 2. Each battery compartment 210 can be used to accommodate batteries for charging. The battery storage assembly 1 can be moved to the side of the opening of the battery compartment 210 to place or remove batteries from the battery compartment 210, thereby realizing the transfer of batteries between multiple battery compartments 210. The battery rack 2 has a frame structure with multiple columns 220 in the vertical direction. The column 220 on the side of each battery rack 2 facing the lifting and transfer device located in the middle is the inner column, which is used for lifting and guiding the lifting and transfer device.

[0131] The lifting and transfer device of the battery storage assembly 1 stores and retrieves batteries relative to the battery compartments 210 of each battery rack 2 by lifting and moving, without the need for horizontal movement. Therefore, it can save the space occupied by the entire battery storage assembly 1 and is highly efficient.

[0132] Meanwhile, the lifting and transfer device uses the inner column of the battery rack 2 as a guide column to achieve lifting and moving relative to the battery rack 2, which simplifies the overall structure of the battery storage component 1, improves the overall reliability by reducing the degree of freedom in handling batteries, and makes the structure more compact.

[0133] The specific structure of the lifting and transferring device is as follows: Figure 1 and Figure 2 As shown: The lifting and transferring device includes a battery loading and unloading mechanism 110, a guiding mechanism 120, and a transmission mechanism 130. The battery loading and unloading mechanism 110 is used to load and unload battery packs from each battery compartment 210 located on the battery rack 2. The guiding mechanism 120 includes a guiding component 122 and at least two guide posts 121. The guide posts 121 are arranged vertically, and the guiding component 122 connects the guide posts 121 and the battery loading and unloading mechanism 110. In this embodiment, the guide posts 121 are formed on the uprights 220 of the battery rack 2 (see...). Figure 8 The inner side of the battery rack 2 is used as the guide surface of the guide post 121 so that the guide assembly can cooperate to achieve the purpose of guiding in the vertical direction.

[0134] like Figure 1 and Figure 2 As shown, in this embodiment, the transmission mechanism 130 specifically includes a chain 131 and two sprockets 132; the sprockets 132 are fixed on the guide post 121, the chain 131 is sleeved on the two sprockets 132, and both ends of the chain 131 are fixedly connected to the battery pick-and-place mechanism 110. Rotation of any sprocket 132 causes the chain 131 to move in the vertical direction to drive the battery pick-and-place mechanism 110 to move up and down.

[0135] The battery pick-and-place mechanism 110 is raised and lowered via the sprocket 132 and chain 131. The chain 131 and sprocket 132 have an enclosed structure, resulting in stable transmission and enabling the battery pick-and-place mechanism 110 to rise and fall smoothly. Furthermore, the battery pick-and-place mechanism 110 moves vertically along the guide post 121, improving positioning and pick-and-place efficiency.

[0136] In specific implementation, such as Figure 1-3 As shown, two sprockets 132 can be respectively disposed at the upper and lower ends of the guide post 121. A chain 131 can be vertically mounted on the two sprockets 132. Either of the two sprockets 132 can serve as the driving sprocket 132, driven by a drive motor 151, thereby moving the chain 131 and causing the battery pick-and-place mechanism 110, which is fixedly connected to the chain 131, to move vertically. Additionally, a guide assembly 122 can be provided between the battery pick-and-place mechanism 110 and the guide post 121 to improve the stability of the guide. A counterweight mechanism can also be provided and connected to the battery pick-and-place mechanism 110, which can balance the movement of the battery pick-and-place mechanism 110.

[0137] In a preferred embodiment, the two ends of the chain 131 are arranged at a predetermined interval along the vertical direction on the side wall of the battery pick-and-place mechanism 110.

[0138] In specific implementation, such as Figure 6 As shown, the battery pick-and-place mechanism 110 can be fixed to both ends of the chain 131, thereby achieving follow-up movement with the chain 131. When fixed to the battery pick-and-place mechanism 110, there can be a preset gap between the two ends of the chain 131, which on the one hand facilitates leaving enough space for connection, and on the other hand makes the connection more stable.

[0139] Specifically, such as Figure 6As shown, the two ends of the chain 131 are vertically connected to the upper and lower edges of the side wall of the battery loading and unloading mechanism 110. This results in a larger relative distance between the two connecting ends of the chain 131, making the connection more stable.

[0140] As a preferred implementation method, such as Figure 6 As shown, at least one end of the chain 131 is movable in the vertical direction relative to the battery pick-and-place mechanism 110 to adjust the tension of the chain 131. This makes the transmission of the chain 131 to the battery pick-and-place mechanism 110 smoother and more accurate.

[0141] In specific implementation, such as Figure 6 As shown, the chain 131131 has two ends, a first end 1311 and a second end 1312. Both ends 1311 and 1312 are connected to the battery pick-and-place mechanism 110, and the distance between the first end 1311 and the second end 1312 is adjustable. The battery pick-and-place mechanism 110 includes a mounting member 112 for fixing the chain 131. Specifically, the mounting member 112 has connecting portions, through which the first end 311 and the second end 312 are connected to the mounting member 112 from above and below, respectively. The connecting portions specifically include a connecting rod 141, a fixing seat 142, and multiple nuts 143. One end of the connecting rod 141 has a pin hole for fixing to the end of the chain 131131 by a pin connection, enabling a simple and reliable connection between the connecting rod 141 and the end of the chain 131131. The other end of the connecting rod 141 has threads, and the fixing seat 142 is fixed to the mounting part 112. The fixing seat 142 is provided with a mounting hole for the threaded end of the connecting rod 141 to pass through. The nuts 143 are fixed to the threaded end of the connecting rod 141 by threaded connection so that the connecting rod 141 is positioned on the fixing seat 142.

[0142] Alternatively, the connecting part can be located at other positions on the battery loading and unloading mechanism 110, depending on the number and position of the transmission mechanism 130.

[0143] In a preferred embodiment, at least one transmission mechanism 130 is provided on each side of the battery loading and unloading mechanism 110, and the number of guide posts 121 is at least four. Specifically, each battery rack 2 located on both sides of the lifting and transferring device should be provided with at least two uprights 220 close to the lifting and transferring device as guide posts 121 to improve lifting stability and enable the battery loading and unloading mechanism 110 to load and unload batteries more reliably and accurately. To improve the positioning effect, guide posts 121 can also be provided at the middle position on both sides of the battery loading and unloading mechanism 110, or guide posts 121 different from the uprights 220 of the battery rack 2 can be provided at the four ends of the battery loading and unloading mechanism 110.

[0144] In specific implementation, the transmission mechanism 130 is set on the inner column of the battery rack, so there can be four. The four transmission mechanisms 130 are respectively set at the four ends of the battery pick-up and place mechanism 110, and the four guide columns 121 are located at the four ends of the battery pick-up and place mechanism 110.

[0145] The number of transmission mechanisms 130 can be selected according to the actual situation. Generally, each transmission mechanism 130 corresponds to a guide post 121 or guide surface to guide the battery picking and placing mechanism 110 to improve the smoothness of movement.

[0146] As a preferred implementation method, such as Figure 1 As shown, the two ends of the chain 131 are respectively connected to the upper and lower corners of the corresponding ends of the battery loading and unloading mechanism 110. Thus, each end has a drive chain 131, which also makes the transmission smooth.

[0147] As a preferred implementation method, such as Figure 4 and Figure 5 As shown, the battery storage assembly 11 also includes a top plate 160 and a counterweight mechanism 170. The top plate 160 is disposed on top of the guide mechanism 120120. The counterweight mechanism 170 includes a counterweight block 171, a counterweight cable 172, and a pulley system. The pulley system includes a lifting pulley 1731, a counterweight pulley 1732, and a transition pulley 1733. The lifting pulley 1731 is connected to the battery loading and unloading mechanism 110, the counterweight pulley 1732 is connected to the counterweight block 171, and the transition pulley 1733 is connected to the counterweight cable 172. The transition pulley 1733 is used to change the extension direction of the counterweight cable 172 so that the counterweight cable 172 passes around the lifting pulley 1731 and the counterweight pulley 1732. The two ends of the counterweight cable 172 are respectively connected to the top plate 160, and the counterweight cable 172 passes around the lifting pulley 1731, the transition pulley 1733, and the counterweight pulley 1732 in sequence.

[0148] like Figure 4 and Figure 5As shown, in a specific implementation, the lifting pulley 1731 is located at the bottom of the battery loading and unloading mechanism 110, and the outer walls of both side plates 111 of the battery loading and unloading mechanism 110 are connected to the lifting pulley 1731; this allows the counterweight cable 172 to pass under the battery loading and unloading mechanism 110, which not only balances the lifting and lowering movement of the battery loading and unloading mechanism 110, but also serves as a safety measure. The counterweight pulley 1732 is connected to the top of the counterweight block 171; this allows the counterweight cable 172 to pass over the top of the counterweight block 171, avoiding interference with the counterweight block 171. In addition, the pulley block includes at least two transition pulleys 1733, namely a first transition pulley 17331 and a second transition pulley 17332. The first transition pulley 17331 is located above the lifting pulley 1731, and the counterweight cable 172 extends vertically upward after passing over the lifting pulley 1731 and connects to the first transition pulley 17331. The second transition pulley 17332 is located above the counterweight pulley 1732, and the counterweight cable 172 extends vertically downward after passing over the second transition pulley 17332 and connects to the counterweight pulley 1732. Thus, by having the counterweight cable 172 sequentially pass over the lifting pulley 1731, the transition pulley 1733, and the counterweight pulley 1732, the counterweight block 171 and the battery loading / unloading mechanism 110 are connected, enabling the counterweight block 171 to balance the lifting and lowering movement of the battery loading / unloading mechanism 110.

[0149] Preferably, the second transition pulley 17332 is at the same horizontal position as the first transition pulley 17331, thereby avoiding space waste caused by the height difference. In addition, the transition pulley 1733 can also be fixedly connected to the top plate 160 to realize the change of the direction of the counterweight cable 172.

[0150] In a preferred embodiment, the battery transfer device further includes a drive mechanism 150, which includes at least one drive motor 151. The drive motor 151 is connected to any sprocket 132 in the transmission mechanism 130 to drive the sprocket 132 to rotate and drive the battery pick-and-place mechanism 110 to move up and down.

[0151] In practical implementation, the drive motor 151 can be connected to either the upper or lower sprocket 132. The sprocket 132 connected to the drive motor 151 is the driving sprocket, which can drive the chain 131 to rotate; correspondingly, the other sprocket 132 is the driven sprocket 132. Furthermore, the drive motor 151 can be arranged at a suitable position, either above or below, to adapt to various requirements.

[0152] As a preferred implementation method, such as Figure 3As shown, there are two drive motors 151, which are located on one side of the battery loading and unloading mechanism 110. Each drive motor 151 is connected to a sprocket 132 positioned opposite each other on both sides of the battery loading and unloading mechanism 110, allowing the two sprockets 132 to rotate synchronously. The two sides of the battery loading and unloading mechanism 110 refer to the two sides with the extension / retraction direction of the battery loading and unloading mechanism 110 as the axis. This arrangement of the drive motors 151 is more rational and ensures that the synchronous rotation of the sprockets 132 on both sides of the battery loading and unloading mechanism 110 drives the battery loading and unloading mechanism 110 to move smoothly.

[0153] As a preferred implementation method, such as Figure 3 As shown, the drive mechanism 150 also includes a coaxial connector 152. The output shaft of the drive motor 151 is connected to the input end of the coaxial connector 152, and the coaxial connector 152 passes through and connects two corresponding sprockets 132. This enables the sprockets 132 on both sides of the battery loading and unloading mechanism 110 to rotate synchronously.

[0154] In the above embodiment, the guide mechanism 120 can reuse the columns 220 of the battery rack 2. It can reuse the columns 220 of one side of the battery rack 2, or it can reuse both columns 220 of both sides of the battery rack 2 simultaneously. This reduces space waste, making the space more compact and reducing the floor area. On the other hand, the battery storage component 1 can be closer to the battery rack 2, reducing the retrieval and placement distance and improving retrieval and placement efficiency. Correspondingly, the space between the battery rack 2 and the battery transfer equipment is more compact, further reducing the floor area.

[0155] As a preferred implementation method, such as Figure 1 and Figure 7 As shown, the guide assembly 122 includes a guide rail 1221 and a guide shoe 1222. The guide rail 1221 is disposed on the guide post 121 and extends in the vertical direction. The guide shoe 1222 is disposed on the battery pick-and-place mechanism 110 and positioned on the guide rail 1221. The guide shoe 1222 can move along the extension direction of the guide rail 1221.

[0156] More specifically, such as Figure 7 As shown, the surface of the guide rail 1221 has a protrusion 12211, which extends toward the direction where the guide shoe 1222 is disposed. The guide shoe 1222 is positioned on at least one side of the protrusion 12211. The guide shoe 1222 has a vertically extending guide groove 12221 for accommodating the protrusion 12211. The inner surface of the guide groove 12221 slides or rolls in contact with at least one side of the protrusion 12211. The protrusion 12211 of the guide rail 1221 improves the positioning effect; and at least one guide side can also be arranged through the protrusion 12211 to enhance the guiding capability.

[0157] Additionally, the counterweight mechanism 170 may also have a guide assembly to guide the counterweight; the specific structure of the guide assembly may be the aforementioned guide rail and guide shoe, or a guide wheel assembly, or other structural forms. For example... Figure 1 and Figure 2 As shown, the counterweight mechanism is equipped with guide rails and guide shoes on both sides for guidance.

[0158] Example 2

[0159] This embodiment also provides a battery storage assembly for a battery storage area in a battery swapping station or energy storage station. Its structure is largely the same as the battery storage assembly in Embodiment 1, except that the transmission mechanism of the lifting and transferring device in this embodiment is not a sprocket and chain drive. Specifically, as shown below... Figure 9 and Figure 10 As shown, the transmission mechanism 130 includes a drive wheel 134, a driven wheel 135, and a synchronous belt 133. The drive wheel 134 and the driven wheel 135 are both fixed on the guide post 121. The synchronous belt 133 is sleeved on the drive wheel 134 and the driven wheel 135, and both ends of the synchronous belt 133 are fixedly connected to the battery pick-and-place mechanism 110. By driving the drive wheel 134 to rotate, the synchronous belt 133 moves in the vertical direction, thereby driving the battery pick-and-place mechanism 110 to move up and down.

[0160] The battery pick-and-place mechanism 110 described above can move up and down in the vertical direction by clamping the synchronous belt 133 in the vertical direction. It has a simple structure, high transmission accuracy, stable lifting process, and is easy to maintain.

[0161] In specific implementation, such as Figure 10 As shown, the driving wheel 134 and the driven wheel 135 can be respectively disposed at the upper and lower ends of the guide post 121. The synchronous belt 133 can be vertically sleeved on the two driving wheels 134. Either the driving wheel 134 or the driven wheel 135 can be disposed at the upper end, and the other can be vertically disposed at the lower end. Correspondingly, the drive motor 151 for driving the driving wheel 134 to rotate can also be disposed above or below the guide post 121. In addition, a guide assembly 120 can be disposed between the battery loading / unloading mechanism 110 and the guide post 121 to improve the stability of the guide. A counterweight mechanism can also be disposed and connected to the battery loading / unloading mechanism 110. The counterweight mechanism can balance the movement of the battery loading / unloading mechanism 110.

[0162] In a preferred embodiment, the two ends of the synchronous belt 133 are connected to the side wall of the battery pick-and-place mechanism 110 at a predetermined interval along the vertical direction.

[0163] In practical implementation, the synchronous belt 133 can be a long strip, wound around the driving pulley 134 and the driven pulley 135, and connected to the battery pick-and-place mechanism 110 to form a ring structure. Both ends of the synchronous belt 133 can be connected to the battery pick-and-place mechanism 110 respectively, making the connection between the battery pick-and-place mechanism 110 and the synchronous belt 133 more stable, and allowing the synchronous belt 133 to form a near-closed structure, preventing power loss during transmission.

[0164] Example 3

[0165] This embodiment also provides a battery storage assembly for a battery storage area in a battery swapping station or energy storage station. Its structure is largely the same as the battery storage assembly in Embodiment 1, except that the transmission mechanism of the lifting and transferring device in this embodiment is not a sprocket and chain drive. Specifically, as shown below... Figure 11 As shown, the transmission mechanism 130 includes a rack 136 and a gear 137. The gear 137 is connected to the battery pick-and-place mechanism 110. The rack 136 is arranged vertically on the guide mechanism 120. The gear 137 and the rack 136 mesh with each other to drive the battery pick-and-place mechanism 110 to move up and down along the guide mechanism 120.

[0166] Through the aforementioned gear 137 and rack 136 structure, the gear 137 can drive the battery pick-and-place mechanism 110 to move up and down; furthermore, the gear 137 and rack 136 themselves have a certain meshing ability, and the meshing of the gear 137 and rack 136 allows the battery pick-and-place mechanism 110 to stop at a certain height position; furthermore, the lifting height of the battery pick-and-place mechanism 110 can be adjusted by changing the length of the rack 136, which facilitates adjustment in the height direction.

[0167] In a preferred embodiment, the transmission mechanism 130 further includes a connecting member 138, such as... Figure 11 and Figure 14 As shown, the connector 138 is vertically disposed on the guide mechanism 120 and fixedly connected to the guide mechanism 120; the connector 138 includes a first wall 1381, a second wall 1382 and a third wall 1383, which are sequentially connected to form a chamber with an opening on one side, the chamber being used to accommodate the gear 137, and the rack 136 being formed on the inner surface of the first wall 1381 or the third wall 1383.

[0168] The rack 136 can be fixedly connected to the guide mechanism 120 via the connector 138, forming a C-shaped receiving cavity in which the gear 137 moves up and down. When the gear 137 is positioned within this receiving cavity, the connector 138 can restrict movement in three directions on the horizontal plane. Figure 11 As shown, the connector 138 is typically a long strip structure.

[0169] In specific implementation, such as Figure 11 and Figure 14 As shown, the end face of gear 137 corresponding to the opening of the receiving cavity is usually used to connect with the drive shaft, thereby limiting the displacement of gear 137 in the fourth direction on the horizontal plane, so that the rotation of gear 137 is transformed into up and down movement.

[0170] like Figure 11 As shown, the connector 138 can be connected to the guide mechanism 120 via the outer side of the second wall 1382, or via the outer side of the first wall 1381 or the outer side of the third wall 1383. For different connection methods, the drive motor 151 can also have different placement positions, for example, as... Figure 1 As shown, the drive motor 151 can be located outside the battery pick-and-place mechanism 110 and between the guide mechanisms 120.

[0171] As a preferred implementation method, such as Figure 14 As shown, the rack 136 is disposed on the inner surface of the first wall 1381, the third wall 1383 has a smooth surface, and the gap between the tooth tip of the gear 137 and the third wall 1383 is smaller than the tooth height of the gear 137.

[0172] In practical implementation, the smooth surface of the third wall 1383 can be the inner surface of the third wall 1383. Or, as... Figure 12-14 As shown, a top block 1384 can also be provided. The top block 1384 is disposed on the inner surface of the third wall 1383, and the side surface of the top block 1384 is a smooth surface for engaging with the tooth tip of the gear 137. Using the top block 1384 as a smooth surface facilitates processing and manufacturing, and also makes it easy to replace when the top block 1384 fails.

[0173] It should be noted that the rack 136 can also be disposed on the inner surface of the third wall 1383, and correspondingly the first wall 1381 has a smooth surface. The smooth surface can restrict the radial position of the gear 137, so that the gear 137 meshes with the rack 136 to transmit power. During the power transmission process, the gear 137 and the rack 136 are always meshed to transmit power.

[0174] As a preferred implementation method, such as Figure 12 and Figure 14 As shown, the end face of gear 137 facing the second wall 1382 is provided with a plurality of balls 1371 protruding from the end face of gear 137, and a rolling or sliding connection is achieved between the plurality of balls 1371 and the second wall 1382. By setting the balls 1371 between the second wall 1382 and gear 137 to achieve a rolling or sliding connection, the resistance between the second wall 1382 and gear 137 can be reduced, making the movement of gear 137 more stable.

[0175] In specific implementation, such as Figure 12 As shown, a groove 1372 is provided on the end face of the gear 137, and multiple balls 1371 are disposed in the groove 1372; the end face with the balls 1371 is disposed opposite to the inner surface of the second wall 1382.

[0176] In specific implementation, a stop 1385 may also be provided at the opening of the connector 138, specifically, as follows: Figure 14 As shown, both the first wall 1381 and the third wall 1383 have a stop 1385 at their ends. The stop 1385 connects to the sidewall of the opening in the first wall 1381 or the third wall 1383 and is parallel to the second wall 1382. Furthermore, the distance between the stop 1385 connected to the first wall 1381 and the stop 1385 connected to the third wall 1383 is sufficient to accommodate the drive shaft. The space restricted between the stop 1385 and the second wall 1382 can be used to install the top block 1384 and the rack 136, as shown. Figure 14 As shown, when the length of the stop block 1385 exceeds the thickness of the top block 1384 and the rack 136, it can also play a certain limiting role on the gear 137.

[0177] As a preferred implementation method, such as Figure 11 and Figure 15 As shown, the battery storage assembly 1 also includes a mounting mechanism 144. The gear 137 is movably mounted on the side of the battery loading and unloading mechanism 110 via the mounting mechanism 144 to adjust the fit between the gear 137 and the second wall 1382. This adjustment of the fit between the gear 137 and the second wall 1382 also adjusts the effective contact area between the gear 137 and the first wall 1381 and the third wall 1383.

[0178] Specifically, such as Figure 15 As shown, the mounting mechanism 144 includes a fixed plate 147 that can move along the axial direction of the gear 137, a bearing 145 fixed on the fixed plate 147, and a synchronous shaft 146 connecting the gear 137 and the bearing 145.

[0179] In specific implementation, such as Figure 15 As shown, the fixing plate 147 is connected to the side plate 111 of the battery loading and unloading mechanism 110, and can be adjusted axially relative to the side plate 111 along the gear 137. The fixing plate 147 is provided with a through hole for accommodating the bearing 145, and the inner surface of the through hole is in contact with the outer surface of the bearing 145.

[0180] Furthermore, the structure of the guide mechanism of the lifting and transferring device in this embodiment is also different from that in Embodiment 1, such as... Figure 11 and Figure 16As shown, the guiding mechanism 120 also includes a guide wheel assembly 123, which is disposed on the inner surface of the side plate 111 of the battery loading and unloading mechanism 110 and abuts against the side wall of the guide post 121; conversely, the transmission mechanism 130 is disposed on the outer surface of the side plate 111 of the battery loading and unloading mechanism 110. Figure 17 and Figure 18 As shown, the guide wheel assembly 123 includes a bearing housing 1231, a fixed shaft 1232, ball bearings 1233, and a guide wheel 1234. The bearing housing 1231 is a mounting base used to fix the battery loading / unloading mechanism 110 to the bearing housing 1231 via bolts or other means. The surface of the bearing housing 1231 has a shaft hole through which the fixed shaft 1232 passes, allowing the fixed shaft 1232 to be mounted on the bearing housing 1231. The guide wheel 1234 is connected to the fixed shaft 1232 via two sets of ball bearings 1233, enabling the guide wheel 1234 to rotate relative to the fixed shaft 1232 with low resistance, thus achieving the purpose of positioning and rolling on the guide post 121.

[0181] Additionally, the guide wheel assembly 123 may also include an adjusting member for adjusting the distance between the bearing housing 1231 and the guide post 121. For example... Figure 16 As shown, the adjusting component includes a fixing plate 1236 and an adjusting bolt 1235 fixed to the battery loading and unloading mechanism 110. The fixing plate 1236 has a threaded hole extending in the adjusting direction. The adjusting bolt 1235 is screwed into the threaded hole, and the end of the adjusting bolt 1235 abuts against the bearing seat 1231 of the guide wheel assembly 123. By turning the adjusting bolt 1235, the adjusting bolt 1235 can push the bearing seat 1231 to move towards the guide post 121, thereby adjusting the distance between the guide wheel 1234 of the guide wheel assembly 123 and the guide post 121.

[0182] Example 4

[0183] This embodiment also provides a battery storage assembly for a battery storage area in a battery swapping station or energy storage station. Its structure is largely the same as the battery storage assembly in Embodiment 3, except that the transmission mechanism of the lifting and transferring device in this embodiment is not a gear and rack drive. Specifically, as shown below... Figure 19 As shown, the transmission mechanism 130 includes a drum 1391 and a traction rope 1392. One end of the traction rope 1392 is connected to the battery pick-and-place mechanism 110, and the other end of the traction rope 1392 is connected to the drum 1391. The rotation of the drum 1391 causes the traction rope 1392 to wind around the drum 1391, thereby driving the battery pick-and-place mechanism 110 to move up and down along the guide post 121.

[0184] By winding or releasing the traction rope 1392 through the aforementioned drum 1391, the length of the traction rope 1392 is changed to drive the lifting and lowering movement of the battery pick-and-place mechanism 110. This transmission method is simple; the lifting and lowering movement of the battery pick-and-place mechanism 110 can be controlled by controlling the number of turns the drum 1391 winds around the traction rope 1392. In addition, the height can be adjusted by adjusting the height of the guide post 121 and the length of the traction rope 1392.

[0185] The following describes the implementation of the battery storage component 1 provided by the present invention in further detail with reference to its specific structural form.

[0186] In practice, the drum 1391 is typically driven by a drive motor 151. The drum 1391 is connected to the output shaft of the drive motor 151, and the drive motor 151 drives the drum 1391 to rotate, thereby winding or releasing the traction rope 1392. By fixing the position of the drive motor 151, the position of the drum 1391 can be relatively fixed.

[0187] In a preferred embodiment, the drum 1391 is disposed on the top of the guide mechanism 120, and the vertical cross-section of the connection between the drum 1391 and the traction rope 1392 passes through the center of gravity of the battery loading and unloading mechanism 110.

[0188] In specific implementation, such as Figure 19 As shown, the top of the guide mechanism 120 is provided with a crossbeam 148, which can be used to install the drive motor 151. The drum 1391 is located above the battery pick-and-place mechanism 110. The traction rope 1392 extending from the drum 1391 is directly connected to the battery pick-and-place mechanism 110. Specifically, it is connected to a certain height in the vertical direction where the center of gravity of the battery pick-and-place mechanism 110 is located, so that the battery pick-and-place mechanism 110 can be raised and lowered smoothly.

[0189] Example 5

[0190] This embodiment also provides a battery storage component for use in the battery storage area of ​​a battery swapping station or energy storage station. Its structure is largely the same as the battery storage component in Embodiment 3, except that, as... Figure 20 As shown, the transmission mechanism 130 in this embodiment includes a traction sheave 1331, a counterweight block 1333, and a counterweight cable 1332. The counterweight cable 1332 is sleeved on the traction sheave 1331 and is connected to the counterweight block 1333 and the battery pick-and-place mechanism 110 respectively. The rotation of the traction sheave 1331 drives the counterweight cable 1332 to move. The counterweight block 1333 moves with the movement of the counterweight cable 1332, so that the battery pick-and-place mechanism 110 moves up and down along the guide post 121.

[0191] The rotation of the traction sheave 1331 drives the movement of the counterweight cable 1332, which is connected to both the counterweight block 1333 and the battery loading / unloading mechanism 110. This causes relative movement between the counterweight block 1333 and the battery loading / unloading mechanism 110, resulting in the lifting and lowering of the battery loading / unloading mechanism 110. This transmission method is simple; controlling the lifting and lowering of the counterweight block 1333 controls the lifting and lowering of the battery loading / unloading mechanism 110. Furthermore, it facilitates vertical expansion by increasing the length of the counterweight cable 1332 and the height of the guide post 121.

[0192] In practical implementation, the traction sheave 1331 is typically driven by a drive motor 151. The traction sheave 1331 is connected to the output shaft of the drive motor 151. The drive motor 151 drives the traction sheave 1331 to rotate, thereby tractioning the counterweight cable 1332 through friction, and controlling the relative movement of the counterweight block 1333 and the battery loading / unloading mechanism 110. By fixing the position of the drive motor 151, the position of the traction sheave 1331 can be relatively fixed. Figure 20 As shown, the drive motor 151 can be fixed to the top of the column 220, and its specific position can be arranged according to the actual situation.

[0193] In specific implementations, the counterweight cable 1332 can be connected to the counterweight block 1333 and the battery loading / unloading mechanism 110 in various forms. The following description, in conjunction with specific structural forms, further illustrates the implementation of the battery storage assembly 1 provided by the present invention.

[0194] As a preferred implementation method, such as Figure 19 As shown, the transmission mechanism 130 also includes a lifting wheel 1341 and a counterweight wheel 1342. The lifting wheel 1341 is connected to the battery loading and unloading mechanism 110, and the counterweight wheel 1342 is connected to the counterweight block 1333. The top of the guide column 121 has a crossbeam 148, and both ends of the counterweight cable 1332 are connected to the crossbeam 148 respectively. The counterweight cable 1332 passes through the lifting wheel 1341, the traction wheel 1331, and the counterweight wheel 1342 in sequence.

[0195] like Figure 20 and Figure 21 As shown, in a specific implementation, the lifting wheel 1341 is located at the bottom of the battery loading and unloading mechanism 110, and the outer walls of both side plates 111 of the battery loading and unloading mechanism 110 are connected to the lifting wheel 1341; this allows the counterweight cable 1332 to pass under the battery loading and unloading mechanism 110, which not only balances the lifting and lowering movement of the battery loading and unloading mechanism 110, but also serves as a safety measure. The counterweight wheel 1342 can be connected to the bottom of the counterweight block 1333; this allows the counterweight cable 1332 to pass under the counterweight block 1333, avoiding interference with the counterweight block 1333. The counterweight wheel 1342 can also be connected to the top of the counterweight block 1333.

[0196] That is, such as Figure 20 and Figure 21 As shown, after one end of the counterweight cable 1332 is connected to one end of the crossbeam 148, it extends downward and successively passes around the lifting wheels 1341 on both sides of the bottom of the battery loading and unloading mechanism 110, extends upward and passes around the traction wheel 1331, then extends downward and passes around the counterweight wheel 1342, and finally extends upward and connects to the other end of the crossbeam 148. Thus, the lifting and moving of the battery loading and unloading mechanism 110 can be controlled by traction counterweight cable 1332.

[0197] As another preferred implementation, such as Figure 22 As shown, the transmission mechanism 130 also includes a first transition wheel 1351, which is connected to the counterweight cable 1332 and is located above the battery pick-and-place mechanism 110; the vertical cross-section of the connection between the first transition wheel 1351 and the counterweight cable 1332 passes through the center of gravity of the battery pick-and-place mechanism 110; the vertical height of the traction wheel 1331 is higher than the vertical height of the first transition wheel 1351.

[0198] Furthermore, the traction sheave 1331 is positioned above the counterweight 1333, and the vertical cross-section of the connection point between the traction sheave 1331 and the counterweight cable 1332 passes through the center of gravity of the counterweight 1333. Through the arrangement of the first transition sheave 1351 and the traction sheave 1331, the projection of the connection point between the counterweight cable 1332 and the battery loading / unloading mechanism 110 onto the battery loading / unloading mechanism 110 passes through the center of gravity of the battery loading / unloading mechanism 110. Similarly, the traction sheave 1331 ensures that the projection of the connection point between the counterweight cable 1332 and the counterweight 1333 onto the battery loading / unloading mechanism 110 passes through the center of gravity of the counterweight 1333, resulting in smooth movement.

[0199] As another preferred implementation, such as Figure 23 As shown, the transmission mechanism 130 also includes a second transition wheel 1352, which is connected to the counterweight cable 1332 and located above the counterweight block 1333. The vertical cross-section of the connection between the second transition wheel 1352 and the counterweight cable 1332 passes through the center of gravity of the counterweight block 1333. The traction wheel 1331 is located between the first transition wheel 1351 and the second transition wheel 1352, and the vertical height of the traction wheel 1331 is not lower than the vertical height of the second transition wheel 1352. That is, the battery loading and unloading mechanism 110 can also be controlled to move up and down by the positional arrangement of the first transition wheel 1351, the second transition wheel 1352, and the traction wheel 1331.

[0200] Accordingly, in specific implementation, different connection methods can be arranged between the traction wheel 1331 and the battery loading and unloading mechanism 110 and the counterweight 1333 as needed, such as the combination of the lifting wheel 1341 and the counterweight wheel 1342, the first transition wheel 1351 and the traction wheel 1331, or the first transition wheel 1351 and the second transition wheel 1352.

[0201] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
