Description

[0001] This application is a division of a Chinese invention patent with an application date of December 31, 2020, application number 202011634701.2, and name “Battery transfer system and battery swap station or energy storage station”. Technical Field

[0002] The invention relates to a battery transport system and a battery replacement station or an energy storage station. Background Art

[0003] The battery swap station is used to replace batteries in electric vehicles. After the electric vehicle enters the battery swap station and is reliably positioned, the battery swap equipment will replace the electric vehicle. Specifically, the battery swap vehicle removes the battery to be replaced from the electric vehicle and places it on the battery transport device, which then transports the battery to be replaced to the charging rack; the battery transport device takes the charged new battery from the charging rack and places it on the battery swap vehicle, which then transports the new battery to the predetermined location and installs it on the electric vehicle.

[0004] The battery swap stations and battery transfer systems built in the traditional way have a floor height of less than 4 meters. However, due to the low height of the battery transfer system, the number of batteries that can be accommodated in the battery swap station is also limited. If the number of batteries needs to be increased, it is necessary to add an expansion box for storing batteries next to the battery swap station or energy storage station and increase the number of battery transfer systems. In this way, the floor space required for the construction of the battery swap station will be greatly expanded, greatly increasing the cost of the battery swap station construction and not conducive to improving land utilization. At the same time, the battery transfer system is mostly an integrated structure, which is not only not conducive to transportation and high cost, but also has a long construction period and is not conducive to later expansion and upgrading of battery swap equipment.

[0005] The Chinese patent application with publication number CN106043247A discloses a modular and expandable battery swap station equipment and charging rack. The battery storage modules in the charging rack are stacked together in a building block manner, and the battery transfer device can travel through the battery storage modules. The Chinese patent application with publication number CN208181025U discloses a battery warehouse and a new energy vehicle battery swap station, wherein the battery warehouse has a plurality of battery racks arranged in series, and each battery rack is respectively provided with a corresponding elevator, or the battery racks share one elevator. However, they are all for splicing the charging warehouses in the battery racks. When constructing a battery swap station, the charging warehouses still need to be spliced ​​in sequence, and the battery swap station itself cannot be modularized. Summary of the invention

[0101] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0102] The embodiment of the present invention discloses a battery swap station or energy storage station 3, which is used to replace batteries for electric vehicles. The battery swap station or energy storage station 3 includes a battery transfer system 1, an upper box 320 and a lower box 310 spliced ​​together. Figure 1 As shown, it is a schematic diagram of the structure of the upper box 320 and the lower box 310 spliced ​​up and down, wherein the side wall of the battery swap station or energy storage station 3 is removed. Figure 2 As shown, the battery transport system 1 includes a battery transport device 10, a guide mechanism 120 and a battery rack 2. Figure 3 As shown, the battery rack 2 includes a first frame 221 and a second frame 222 spliced ​​together, and the first frame 221 and the second frame 222 are spliced ​​together to form a plurality of columns 220. The battery rack 2 is used to store battery packs. The first frame 221 and the second frame 222 are quickly assembled into the battery rack 2 by splicing, so as to achieve convenient and quick assembly. Moreover, since the battery transport system 1 is raised vertically, more batteries can be accommodated under the same floor space, and the floor space can be reduced when storing the same number of batteries. At the same time, the first frame 221 and the second frame 222 are very convenient to install and disassemble. In particular, if there is a problem with the operation and detection of the battery transport system 1 at the construction site, the upper battery rack 2 can be quickly disassembled and transported for rework, which greatly reduces the cost.

The guide member 121 is attached to the column 220, and the matching member 122 is connected to the battery transport device 10 and matched with the guide member 121. The column 220 has high structural strength. The guide member 121 is arranged on the column 220, which effectively strengthens the structural connection strength of the guide mechanism 120 and realizes the stable lifting and lowering of the battery transport system 1. At the same time, the guide mechanism 120 has a guiding function, which effectively avoids the displacement and dislocation phenomenon of the battery transport device 10 during the lifting process, and greatly improves the safety and stability of the battery transport system 1.

[0104] In this embodiment, the stacked box-shaped device is divided into two parts, upper and lower, and they are independent of each other. After the components in the box are installed, the stacked box-shaped device can be divided into the upper and lower parts and transported separately to meet the road transportation requirements and facilitate on-site installation and commissioning after transportation. The lower box 310 and the upper box 320 are stacked to reduce the land area and improve the land utilization rate, so that more battery packs can be accommodated under the same land area. The lower box 310 is connected to the upper box 320, so that the battery exchange equipment or battery transfer equipment 10 inside the stacked box-shaped device can move unimpeded along the height direction of the stacked box-shaped device. The extension of the stacked box-shaped device in the height direction can enable the battery exchange station or energy storage station 3 or energy storage station to accommodate more battery packs and more types of battery packs, thereby improving the battery exchange efficiency and operation capacity of the battery exchange station or energy storage station or energy storage station.

[0105] The upper box 320 is provided with a first frame 221, and the upper and lower ends of the first frame 221 are respectively provided with a first reinforcement unit, and the first reinforcement unit extends from the end of the first frame 221 to both sides and is fixed on the wall surface of the upper box 320; the lower box 310 is provided with a second frame 222, and the bottom of the second frame 222 is fixed on the bottom surface of the lower box 310, and the top surface of the second frame 222 is provided with a second reinforcement unit, and the second reinforcement unit extends from the top surface of the second frame 222 to both sides and is fixed on the wall surface of the lower box 310; the first frame 221 and the second frame 222 are fixedly connected to the second reinforcement unit through the first reinforcement unit. The first frame 221 is connected to the upper box 320 through the first reinforcement unit, and the second frame 222 is connected to the lower box 310 through the second reinforcement unit, which effectively strengthens the connection strength between the battery rack 2 and the upper box 320 and the lower box 310. The first frame 221 and the second frame 222 are connected by the first reinforcement unit and the second reinforcement unit, which effectively strengthens the structural strength of the battery rack 2, realizes reliable connection strength of the battery swap station or energy storage station 3, and greatly improves the safety and stability of the battery swap station or energy storage station 3.

[0106] The battery swap station or energy storage station 3 also includes battery compartments 210, and a plurality of battery compartments 210 are arranged on the battery rack 2 in the vertical direction; the battery transfer equipment 10 includes a battery pick-up and placement mechanism 110 and a transmission mechanism 130 for picking up and placing battery packs from the battery compartments 210, and the transmission mechanism 130 is used to drive the battery pick-up and placement mechanism 110 to achieve vertical lifting and movement along the battery rack 2; at least one transmission mechanism 130 is respectively arranged on both sides of the battery pick-up and placement mechanism 110. The battery compartments 210 are used to place battery packs and are arranged on the battery rack 2 in the vertical direction, and can be expanded in the height direction, making full use of the longitudinal space and reducing the floor space. At the same time, the transmission mechanism 130 is used to ensure that the battery pick-up and placement mechanism 110 moves smoothly between the battery compartments 210, thereby achieving the picking and placement of batteries.

[0107] like Figure 5 As shown, the transmission mechanism 130 includes a driving wheel 131, a driven wheel 132 and a synchronous belt 133.

The synchronous belt 133 is sleeved on the driving wheel 131 and the driven wheel 132, and both ends of the synchronous belt 133 are fixedly connected to the battery pick-up and placement mechanism 110. The driving wheel 131 is driven to rotate to move the synchronous belt 133 in the vertical direction to drive the battery pick-up and placement mechanism 110 to move up and down. The column 220 has a high structural strength. The driving wheel 131 and the driven wheel 132 are both fixed on the column 220, which effectively strengthens the structural connection strength of the transmission mechanism 130 and realizes the smooth lifting and lowering of the battery pick-up and placement mechanism 110. At the same time, the battery picking and placing mechanism 110 can be raised and lowered and moved in the vertical direction under the action of the synchronous belt 133 by clamping the vertical synchronous belt 133; the maximum movable distance of the battery picking and placing mechanism 110 relative to the guide mechanism 120 can be extended by extending the length of the synchronous belt 133, which is convenient for adjusting the moving distance of the car and facilitating expansion in the height direction.

At the same time, the guide mechanism 120 has a guiding function, which effectively avoids the displacement and dislocation phenomenon of the battery transport equipment 10 during the lifting process, and greatly improves the safety and stability of the battery transport system 1.

[0109] like Figure 4 As shown, the first frame 221 and the second frame 222 are connected by corresponding positioning components, and the positioning components include corresponding positioning holes 223 and positioning columns 224, one of which is arranged at the bottom of the upper column 220, and the other of which is arranged at the top of the lower column 220. The positioning holes 223 and the positioning columns 224 have a precise positioning function, and the first frame 221 and the second frame 222 are fixed in position by the positioning holes 223 and the positioning columns 224, so that the verticality of the plurality of columns 220 formed after the first frame 221 and the second frame 222 are spliced ​​is higher, which greatly improves the accuracy of the battery transport system 1; at the same time, the connection and fixation are more convenient.

[0110] like Figure 6As shown, the guide member 121 is a guide rail 1211, and the matching member 122 is a guide shoe 1221. The guide rail 1211 extends in the vertical direction and is attached to the column 220; the guide shoe 1221 can move along the extension direction of the guide rail 1211. The friction between the matching member 122 and the guide member 121 is reduced by the guide rail 1211 and the guide shoe 1221, so that the lifting and lowering movement of the battery pick-and-place mechanism 110 relative to the guide mechanism 120 is more stable.

[0111] like Figure 6 As shown, the surface of the guide rail 1211 has a protruding portion 12111, and the protruding portion 12111 extends in the direction of the guide shoe 1221, and the guide shoe 1221 is positioned on at least one side of the protruding portion 12111; the guide shoe 1221 has a guide groove 12211 extending in the vertical direction, and the guide groove 12211 is used to accommodate the protruding portion 12111, and the inner surface of the guide groove 12211 is in sliding or rolling contact with at least one side of the protruding portion 12111. By extending the protruding portion 12111 into the guide groove 12211, the installation between the matching piece 122 and the guide piece 121 is very convenient, and accurate positioning can be achieved, ensuring that the matching piece 122 moves up and down in the vertical direction. At the same time, by sliding or rolling contact between the inner surface of the guide groove 12211 and at least one side of the protruding portion 12111, the friction between the matching piece 122 and the guide piece 121 is further reduced, so that the battery pick-up and placement mechanism 110 can move up and down relative to the guide mechanism 120 more stably.

[0112] The guide rail 1211 is an integrally formed part, and the guide rail 1211 is attached to the side wall surface of the column 220. The guide rail 1211 is made by integrally forming, so that the guide performance of the guide rail 1211 at different positions on the battery rack 2 is consistent, thereby improving the consistency of the guide up and down. At the same time, the installation and setting are very convenient, and the processing and manufacturing are also convenient.

[0113] like Figure 7 As shown, the guide rail 1211 includes a first guide rail 123 and a second guide rail 124 spliced ​​up and down along the length direction of the column 220, and a positioning structure is provided at the connection between the first guide rail 123 and the second guide rail 124. The positioning structure ensures the overall installation accuracy of the guide rail 1211 and the guiding performance of the guide rail 1211. At the same time, the guide rail 1211 is connected in a splicing manner, which is convenient for transportation, maintenance and replacement, and is conducive to expansion in the vertical direction.

[0114] like Figure 8As shown, the positioning structure includes a groove 125 and a protrusion 126, one of the groove 125 and the protrusion 126 is arranged on the end surface of the first guide rail 123, and the other of the groove 125 and the protrusion 126 is arranged on the end surface of the second guide rail 124, and the groove 125 and the protrusion 126 cooperate with each other. The groove 125 and the protrusion 126 have a precise positioning function, and the positioning structure cooperates with the first guide rail 123 and the second guide rail 124 through the groove 125 and the protrusion 126 respectively, so that the verticality of the guide rail 1211 in the vertical direction is higher, which greatly improves the accuracy of the battery transport system 1; at the same time, the connection and fixation are more convenient.

[0115] like Fig. 9 As shown, the two ends of the guide rail 1211 are fixedly connected to the column 220 respectively; the guide mechanism 120 also includes a crimping assembly 127, which is connected to the middle area of ​​the guide rail 1211 to press the guide rail 1211 on the side wall surface of the column 220, and the crimping assembly 127 is adjustable relative to the column 220. The two ends of the guide rail 1211 are fixed to the column 220, so that the two ends are fixed to ensure the verticality of the guide rail 1211, and the middle area is pressed on the column 220 by the crimping assembly 127, and the installation is fast and convenient. At the same time, the crimping assembly 127 is adjustable relative to the column 220, which ensures that the crimping assembly 127 applies a pressing force to the guide rail 1211 and adjusts the setting position of the guide rail 1211 on the column 220, which greatly improves the safety and stability of the battery transport system 1.

[0116] like Fig.10 As shown, the crimping assembly 127 includes a base 1271, a pressing block 1272 and a fastener 1273. The base 1271 is fixed relative to the column 220; the pressing block 1272 includes a pressing block body 12721 and a bending portion 12722. The pressing block body 12721 is matched with the base 1271, and the bending portion 12722 is connected to one end of the pressing block body 12721 and bent to be pressed against the surface of the guide rail 1211; the fastener 1273 passes through the base 1271 and the pressing block body 12721 (not shown in the figure), and fixes the base 1271 and the pressing block 1272. By pressing the bending portion 12722 against the surface of the guide rail 1211, the pressing block 1272 avoids the matching piece 122, thereby ensuring the stability of the guide mechanism 120. At the same time, the pressing block 1272 and the base 1271 are fixed to the column 220 by the fastener 1273, and the installation and setting are very convenient; and in the process of fixing the fastener 1273, the degree of pressing of the pressing block 1272 on the surface of the guide rail 1211 can also be adjusted, and the verticality of the guide rail 1211 can also be adjusted.

[0117] like Fig.10As shown, the connection between the base 1271 and the pressure block body 12721 has a step structure, and the top end surface of the base 1271 fits with the bottom end surface of the pressure block body 12721; there is a gap between the base 1271 and the pressure block body 12721. The step structure can increase the contact area between the base 1271 and the pressure block body 12721, thereby improving the stability of the connection. At the same time, the gap between the base 1271 and the pressure block body 12721 allows the pressure block 1272 to be displaced relative to the base 1271, thereby adjusting the degree of pressure of the pressure block 1272 on the guide rail 1211. A certain gap can be left between the base 1271 and the pressure block body 12721 in both the horizontal and vertical directions. The base 1271 is L-shaped, and the pressure block body 12721 is inverted L-shaped, which are very convenient to process and install.

[0118] In one embodiment, Figure 2 As shown, the battery transport device 10 includes a battery pick-up and placement mechanism 110 and a transmission mechanism 130. The transmission mechanism 130 is connected between the battery pick-up and placement mechanism 110 and the column 220. The transmission mechanism 130 is used to drive the battery pick-up and placement mechanism 110 to move along the column 220. The connection surface between the transmission mechanism 130 and the column 220 and the connection surface between the guide mechanism 120 and the column 220 are the same side wall surface of the column 220. The transmission mechanism 130 and the guide mechanism 120 are located on the same side of the battery rack 2, so that the battery transport system 1 is very convenient to install and set up, and the overall structure is compact and occupies little space.

[0119] In another embodiment, the connection surface between the transmission mechanism 130 and the column 220 and the connection surface between the guide mechanism 120 and the column 220 are different side wall surfaces of the column 220. The transmission mechanism 130 and the guide mechanism 120 are respectively connected to different side wall surfaces of the column 220, so as to adapt to different usage requirements and expand the scope of application. At the same time, the connection on different side wall surfaces of the column 220 has an interaction force, which improves the stability of the overall structure of the battery rack 2.

[0120] In specific implementation, Fig.11 As shown, the transmission mechanism 130 includes a gear 134 and a rack 135, the rack 135 is disposed on one side wall surface of the column 220, and the guide mechanism 120 is a roller 128, and the roller 128 abuts against the other side wall surface of the column 220. In addition, the side wall surface connected to the rack 135 and the side wall surface abutted by the roller 128 are adjacent side wall surfaces.

[0121] like Figure 2As shown, the battery transport device 10 is located between two rows of battery racks 2 arranged opposite to each other at a predetermined interval; the battery transport system 1 includes four guide mechanisms 120, which are respectively located at the four ends of the battery pick-up and placement mechanism 110; at least two guide mechanisms 120 are connected to the columns 220 close to the battery transport device 10 for guidance. The four ends of the battery pick-up and placement mechanism 110 are guided by moving on the four guide mechanisms 120, and at least two guide mechanisms 120 are connected to the columns 220 with high structural strength, so that the lifting and lowering movement of the battery pick-up and placement mechanism 110 is more stable, effectively avoiding the displacement and dislocation of the battery transport device 10 during the lifting process, and greatly improving the safety and stability of the battery transport system 1. At the same time, the battery pick-up and placement mechanism 110 is located between the two rows of battery racks 2 arranged opposite to each other at a predetermined interval, so that the overall structure of the battery transport system 1 is more compact, saving space resources, and further reducing the floor space.
