Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement, and in particular to a battery rack and a battery replacement station. Background Art

[0002] Battery swapping is an important way to replenish energy for new energy vehicles, especially pure electric vehicles. Battery swapping can replenish the vehicle's energy in a very short time, so it is widely favored by users.

[0003] At present, battery swap stations, especially lift-type battery swap stations that require the vehicle to be lifted and the battery swap operation to be performed underneath the vehicle, usually have a battery swap cycle in which the battery swap robot disassembles the deflated battery under the vehicle and exchanges the deflated battery with the stacker. The stacker then puts the deflated battery into the battery compartment, takes out a fully charged battery from another battery compartment, and passes it to the battery swap robot. Finally, the battery swap robot carries the fully charged battery for installation.

[0004] However, in the above-mentioned battery replacement process, the stacker puts back the depleted battery and takes out the fully charged battery in serial action, which results in a relatively long battery replacement cycle and affects the battery replacement efficiency.

[0005] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0007] The battery rack of the present application is provided with a battery cache device capable of caching two power batteries in the lower accommodation space of the frame body, so that during the battery exchange process, while the battery exchange robot is disassembling the low-power battery, the battery connection device can be operated synchronously, and a fully-charged battery can be taken out in advance and placed in the battery cache device. After the battery exchange robot places the low-power battery in the battery cache device, the fully-charged battery can be directly taken away, which greatly shortens the battery exchange cycle, improves the battery exchange efficiency, and improves the service capacity of the battery exchange station. By setting up a lifting drive mechanism, the space utilization rate of the battery rack can be improved.

DETAILED DESCRIPTION

[0072] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "multiple" refers to at least two.

[0074] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0075] First refer to Figure 1 and Figure 2 , the battery rack of the present application is described.

[0076] like Figure 1 and Figure 2 As shown, in order to solve the problem that the serial beat of the stacker in the battery swap station is long and affects the battery swap efficiency, the battery rack 1 of the present application includes a frame body 11 and a battery cache device 2. A plurality of charging positions 12 are formed on the frame body 11, and the charging positions 12 are used to carry the power battery 5 and charge the power battery 5. A accommodating space 13 is formed at the lower part of the frame body 11, and the battery cache device 2 is arranged in the accommodating space 13. The battery cache device 2 includes a lifting drive mechanism 21, a first cache position and a second cache position, the first cache position and the second cache position are arranged in the height direction, and the first cache position and the second cache position have no relative movement in the height direction, and the lifting drive mechanism 21 is connected to at least one of the first cache position and the second cache position, so that the lifting drive mechanism 21 can drive the first cache position and the second cache position to rise or fall at the same time.

[0077] During the battery swapping process, the battery swapping robot removes the deflated battery from the vehicle to be swapped, and carries the deflated battery to one side of the battery rack 1. At the same time, the battery docking device (such as a stacker) on the other side of the battery rack 1 takes a fully charged battery 7 from the charging position 12 and waits. The battery swapping robot lifts the deflated battery and transfers it to the first cache position, then descends and waits. Then the lifting drive mechanism 21 drives the first cache position and the second cache position to rise at the same time, and the battery docking device transfers the fully charged battery to the second cache position, and then the battery docking device exits the second cache position. Finally, the battery swapping robot lifts the fully charged battery on the second cache position and moves it out of the second cache position, and carries the fully charged battery to swap the battery for the vehicle to be swapped. The battery docking device removes the deflated battery from the first cache position and transports it to the charging position 12 for charging.

[0078] The battery rack 1 of the present application is provided with a battery cache device 2 that can cache two power batteries 5 in the lower accommodation space 13 of the frame body 11, so that during the battery exchange process, while the battery exchange robot disassembles the low-power battery, the battery connection device can act synchronously, taking out a fully charged battery in advance and placing it in the battery cache device 2. After the battery exchange robot places the low-power battery in the battery cache device 2, it can directly take away the fully charged battery, which greatly shortens the battery exchange cycle, improves the battery exchange efficiency, and improves the service capacity of the battery exchange station. By setting up a lifting drive mechanism 21, the space utilization rate of the battery rack 1 can be improved. Since the battery exchange robot itself has a certain height and the lifting height of the battery exchange robot is also limited in range, a cache position that is too high or too low is not conducive to battery interaction. By setting up a lifting drive mechanism 21, the present application can use the lifting drive mechanism 21 to drive the two cache positions to rise and fall, which not only adapts to the height of the battery exchange robot, but also saves space, so that the battery rack 1 has more space to arrange batteries.

[0079] Combine the following Figures 1 to 4 , a possible implementation method of the present application is introduced.

[0080] like Figures 1 to 4 As shown, in a possible implementation, the battery rack 1 includes a frame body 11 and a battery cache device 2. Six charging positions 12 are formed on the upper part of the frame body 11, and each charging position 12 can carry a power battery 5 and charge the power battery 5. An accommodating space 13 is formed at the lower part of the frame body 11, and the accommodating space 13 is formed between the lowest charging position 12 and the ground of the battery swap station, and the battery cache device 2 is installed in the accommodating space 13.

[0081] The battery cache device 2 includes two mounting supports 22, each mounting support 22 is provided with a lifting drive mechanism 21, a first support plate 231, a second support plate 232, a first partition plate 251, a second partition plate 252, a connecting plate 261, an external plate 262, a first guide mechanism 271, a second guide mechanism 272, a third guide mechanism 273, a first telescopic drive mechanism 281, a second telescopic drive mechanism 282, and a connecting seat 29.

[0082] Reference Figure 1 and Figure 2 The two mounting supports 22 are arranged on opposite sides of the accommodating space 13. Specifically, the two mounting supports 22 are arranged on both sides of the accommodating space 13 in the horizontal and vertical directions of the power battery 5 entering and exiting the charging compartment 12. The top of each mounting support 22 is fixedly connected to the frame body 11, and the bottom of each mounting support 22 is fixedly connected to the ground of the battery swap station.

[0083] The following reference Figures 2 to 4 , and Figure 2 The battery cache device 2 is introduced by taking the mounting bracket 22 on the left side as an example, and those skilled in the art can understand that Figure 2 The specific arrangement of the mounting bracket 22 on the middle right side and the components mounted thereon are substantially the same as those of the mounting bracket 22 on the left side.

[0084] like Figures 2 to 4 As shown, a lifting drive mechanism 21 is installed on each mounting support 22. In the present application, the lifting drive mechanism 21 is a linear drive mechanism, and more specifically, the linear drive mechanism is a hydraulic cylinder, such as an oil cylinder. The bottom of the hydraulic cylinder is fixedly connected to the mounting support 22, and the top of the hydraulic cylinder is a hydraulic rod, which is telescopically arranged under the action of hydraulic oil.

[0085] The first partition 251 and the second partition 252 are fixedly connected by a connecting plate 261. There are two connecting plates 261, the first partition 251 and the second partition 252 are arranged in a horizontal direction, the first partition 251 is located above the second partition 252, the two connecting plates 261 are arranged vertically, and the vertical ends of each connecting plate 261 are respectively fixedly connected to the lower side of the first partition 251 and the upper side of the second partition 252. After the connection is completed, the first partition 251, the second partition 252 and the two connecting plates 261 are surrounded to form a frame. Each connecting plate 261 is also connected to an external connecting plate 262, which is vertically installed on the side of the connecting plate 261 and extends outward from the side of the connecting plate 261. The two external connecting plates 262 are respectively connected to the mounting support 22 through a first guide mechanism 271. The first guide mechanism 271 is a slider rail assembly, the rail is vertically fixedly connected to the mounting support 22, and the slider is fixedly connected to the external plate 262. Therefore, under the guidance of the first guide mechanism 271, the first partition 251 and the second partition 252 can be simultaneously lifted and lowered on the mounting support 22.

[0086] The connection seat 29 is in an inverted U shape, and the connection seat 29 is fixedly connected to the upper side of the first partition 251. A first through hole 2511 is also provided on the first partition 251 at a position corresponding to the connection seat 29, and a second through hole 2521 is provided on the second partition 252 at a position corresponding to the first through hole 2511. The cylinder body of the hydraulic cylinder passes through the second through hole 2521, and the hydraulic rod passes through the first through hole 2511 and is fixedly connected to the U-shaped bottom of the connection seat 29. In this way, the hydraulic cylinder can drive the first partition 251 and the second partition 252 to complete the lifting and lowering movement.

[0087] The first support plate 231 is slidably connected to the first partition plate 251 through two second guide mechanisms 272, so that a first cache position is formed between the two first support plates 231. The second guide mechanism 272 is a slide rail and slider assembly, the slide rail is fixedly connected to the upper side of the first partition plate 251, and the slider is fixedly connected to the lower side of the first support plate 231. The first telescopic driving mechanism 281 is a first electric push rod, and a first connecting block 2313 is provided on the lower side of the first support plate 231. The first electric push rod is fixedly connected to the upper side of the first partition plate 251, and the output end of the first electric push rod is connected to the first connecting block 2313. In this way, the first support plate 231 has a first extended position and a first retracted position under the drive of the first telescopic driving mechanism 281. When the first support plate 231 is located at the first extended position, the two first support plates 231 can carry the power battery 5. When the first support plate 231 is located at the first retracted position, an avoidance space allowing the power battery 5 to pass through is formed between the two first support plates 231.

[0088] Furthermore, a first step surface 2311 is formed on the first support plate 231, and the first step surface 2311 extends to the end of the first support plate 231. At least one first stopper 241 is also provided on the first support plate 231. In the present application, two first stoppers 241 are provided on each first support plate 231, and the two first stoppers 241 are provided on the rear side of the first step surface 2311, and each first stopper 241 has a part overlapping with the first step surface 2311 in the vertical projection direction. In this way, the first step surfaces 2311 of the two first support plates 231 are used to carry the power battery 5, and the first stoppers 241 on the two first support plates 231 are used to limit the carrying position of the power battery 5. A first avoidance notch 2312 is also provided on each first support plate 231, and the connecting seat 29 extends from the first avoidance notch 2312. The first avoidance notch 2312 is a U-shaped notch, and when the first support plate 231 is at the first retracted position, the first avoidance notch 2312 and the connecting seat 29 do not interfere with each other.

[0089] The second support plate 232 is slidably connected to the second partition plate 252 through two third guide mechanisms 273, so that a second cache position is formed between the two second support plates 232. Among them, the third guide mechanism 273 is a slide rail and slider assembly, the slide rail is fixedly connected to the upper side of the second partition plate 252, and the slider is fixedly connected to the lower side of the second support plate 232. The second telescopic drive mechanism 282 is a second electric push rod, and the lower side of the second support plate 232 is provided with a second connecting block 2323, the second electric push rod is fixedly connected to the upper side of the second partition plate 252, and the output end of the second electric push rod is connected to the second connecting block 2323. In this way, the second support plate 232 has a second extended position and a second retracted position under the drive of the second telescopic drive mechanism 282. When the second support plate 232 is located at the second extended position, the two second support plates 232 can carry the power battery 5. When the second support plate 232 is located at the second retracted position, an avoidance space allowing the power battery 5 to pass through is formed between the two second support plates 232.

[0090] Furthermore, a second step surface 2321 is formed on the second support plate 232, and the second step surface 2321 extends to the end of the second support plate 232. At least one second stopper 242 is also provided on the second support plate 232. In the present application, two second stoppers 242 are provided on each second support plate 232, and the two second stoppers 242 are arranged on the rear side of the second step surface 2321, and each second stopper 242 has a part overlapping with the second step surface 2321 in the vertical projection direction. In this way, the second step surfaces 2321 of the two second support plates 232 are used to carry the power battery 5, and the second stoppers 242 on the two second support plates 232 are used to limit the carrying position of the power battery 5. A second avoidance notch 2322 is also provided on each second support plate 232, and the hydraulic rod of the hydraulic cylinder extends out of the second avoidance notch 2322. The second avoidance notch 2322 is a U-shaped notch, and when the second support plate 232 is at the second retracted position, the second avoidance notch 2322 and the hydraulic rod do not interfere with each other.

[0091] In the above-mentioned arrangement, a lifting drive mechanism 21 is arranged on each mounting support 22, which is conducive to reducing the structural complexity of the device. The first partition 251 and the second partition 252 are fixedly connected by the connecting plate 261, which can ensure the relative position between the first support plate 231 and the second support plate 232. The arrangement of the first guide mechanism 271 can improve the lifting stability of the first support plate 231 and the second support plate 232. By arranging the first telescopic drive mechanism 281, the opposite telescopic movement of the two first support plates 231 can be achieved, which is conducive to improving the transportation safety of the power battery 5 and avoiding collisions during transportation. By arranging the second telescopic drive mechanism 282, the opposite telescopic movement of the two second support plates 232 can be achieved, which is conducive to improving the transportation safety of the power battery 5 and avoiding collisions during transportation. The arrangement of the second guide mechanism 272 is conducive to improving the telescopic stability of the first support plate 231, and the arrangement of the third guide mechanism 273 is conducive to improving the telescopic stability of the second support plate 232. Compared with other driving modes, the linear drive mechanism is used as the lifting drive mechanism 21, which occupies less space and has a simple and stable structure. The first step surface 2311 and the second step surface 2321 are provided to facilitate positioning of the power battery 5. The first stopper 241 and the second stopper 242 are provided to facilitate positioning of the power battery 5.

[0092] It should be noted that the above preferred implementations are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art may adjust the above settings so that the present application can be applied to more specific application scenarios.

[0093] For example, the six charging positions 12 formed on the upper portion of the frame body 11 are merely exemplary, and those skilled in the art may adjust the number of the charging positions 12, and such adjustment does not deviate from the principles of the present application.

[0094] For another example, although the above embodiment is described in combination with two mounting brackets 22, this arrangement is not restrictive, and those skilled in the art can select the number and arrangement of the mounting brackets 22 based on specific application scenarios. For example, the two mounting brackets 22 can be connected as a whole, or the mounting bracket 22 can be omitted, and other components can be arranged on the frame body 11.

[0095] For example, in another replaceable embodiment, although the above embodiment is introduced in conjunction with a lifting drive mechanism 21 provided for each mounting support 22, the specific number of the lifting drive mechanism 21 is not unique. In other embodiments, only one lifting drive device may be provided. For example, a motor may be provided to simultaneously drive two transmission components (such as a gear set or a chain transmission) to simultaneously drive the lifting and lowering of the two first partitions 251 and the two second partitions 252.

[0096] For example, in another replaceable embodiment, although the lifting drive mechanism 21 is introduced in combination with a hydraulic cylinder as an example, the present application does not limit the specific form of the lifting drive mechanism 21. In addition to the hydraulic cylinder, a linear drive mechanism such as a pneumatic cylinder or an electric cylinder can also be used, or a motor and a rack and pinion assembly, a screw nut assembly, a gear chain assembly, etc. can be used as a replacement.

[0097] For example, in another replaceable embodiment, although the two mounting brackets 22 are introduced with the example of being connected to the frame body 11 at the top and connected to the ground of the battery swap station at the bottom, this connection method is not the only one. Under the premise of ensuring the stability of the mounting bracket 22, technical personnel in this field can adjust the specific connection method of the mounting bracket 22, such as the mounting bracket 22 can be connected to the frame body 11 only at the top, or can be connected to the ground of the battery swap station only at the bottom.

[0098] For example, in another replaceable embodiment, although the above-mentioned embodiment is described in conjunction with the first support plate 231 and the second support plate 232 being respectively slidably connected to the first partition plate 251 and the second partition plate 252, the setting method of the present application is not limited to this. In other embodiments, the first support plate 231 and the second support plate 232 can also be fixedly set on the first partition plate 251 and the second partition plate 252, or the first partition plate 251 or the second partition plate 252 can be omitted, and the first support plate 231 and the second support plate 232 are fixedly connected and slidably set on the mounting support 22.

[0099] For example, in another replaceable embodiment, the specific configuration of the first telescopic drive mechanism 281 and the second telescopic drive mechanism 282 is not limited in this application. In addition to electric cylinders, hydraulic cylinders, pneumatic cylinders, motors and screw nut assemblies, motors and gear racks, etc. may also be used.

[0100] For another example, in another alternative embodiment, although the above embodiment is described in conjunction with the first step surface 2311 and the first stopper 241 being provided on the first support plate 231, and the second step surface 2321 and the second stopper 242 being provided on the second support plate 232, the first step surface 2311, the second step surface 2321, the first stopper 241 and the second stopper 242 are not necessarily provided, and those skilled in the art may select them based on specific application scenarios. For example, those skilled in the art may selectively omit at least one of the first step surface 2311, the second step surface 2321, the first stopper 241 and the second stopper 242, or add rubber pads on the first step surface 2311 and the second step surface 2321 to improve the supporting stability of the power battery 5.

[0101] For another example, in another alternative embodiment, although in the above embodiment, the first partition plate 251 and the second partition plate 252 are fixedly connected by the connecting plate 261, the specific connection method of the first partition plate 251 and the second partition plate 252 is not unique, and those skilled in the art can also adjust the method. For example, the first partition plate 251 and the second partition plate 252 are simultaneously fixedly connected to a slider of a first guide mechanism 271, or the first partition plate 251 and the second partition plate 252 are simultaneously connected to the output end of the hydraulic cylinder, etc.

[0102] For example, in the above embodiment, the connection of the connecting plate 261 to the first guide mechanism 271 via the external plate 262 is merely exemplary. In other embodiments, the connecting plate 261 may also be directly connected to the first guide mechanism 271, thereby omitting the external plate 262.

[0103] For example, in another replaceable embodiment, although the above embodiment is introduced in conjunction with a first support plate 231 and a second support plate 232 being provided on each mounting support 22, a first cache position is formed between the two first support plates 231, and a second cache position is formed between the two second support plates 232, but this is only a possible embodiment. In other embodiments, a "C"-shaped frame (C-shaped opening facing downward) can be used to replace the two first support plates 231, or the two first support plates 231 can be fixedly connected as a whole using a connecting piece.

[0104] For another example, although the above embodiment is described in conjunction with a connecting seat 29 provided on the first partition 251 and the hydraulic rod of the hydraulic cylinder is connected to the connecting seat 29, the provision of the connecting seat 29 is not necessary, and the hydraulic rod can also be directly connected to the first partition 251.

[0105] For another example, when the lifting drive mechanism 21 is a hydraulic cylinder, the first through hole 2511, the second through hole 2521, the first avoidance notch 2312 and the second avoidance notch 2322 are required, but when the lifting drive mechanism 21 is other mechanisms, or the setting position of the lifting drive mechanism 21 changes, the first through hole 2511, the second through hole 2521, the first avoidance notch 2312 and the second avoidance notch 2322 are not required, and those skilled in the art can flexibly set them based on specific application scenarios. For example, when the connecting seat 29 is not provided, the hydraulic rod is directly connected to the first partition plate 251, and the first avoidance notch 2312 on the first support plate 231 can be omitted.

[0106] For another example, in another replaceable embodiment, the specific forms of the first guide mechanism 271, the second guide mechanism 272 and the third guide mechanism 273 are not fixed. Although the above embodiments are all described in combination with the slider rail assembly as an example, those skilled in the art may also use a slider assembly, a slide rail slot assembly, etc. for replacement. Of course, providing the first guide mechanism 271, the second guide mechanism 272 and the third guide mechanism 273 is only a more stable embodiment, and those skilled in the art may also omit at least one of the above three guide mechanisms.

[0107] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0108] The present application also provides a battery swap station, which includes a battery swap robot, a battery docking device and the battery rack 1 in the above-mentioned technical implementation, and the battery rack 1 is arranged between the battery swap robot and the battery docking device.

[0109] By installing a battery rack 1 with a battery cache device 2 in a battery swap station, the battery swap cycle can be greatly shortened, the battery swap efficiency can be improved, and the service capacity of the battery swap station can be improved. The battery cache device 2 is provided with a lifting drive mechanism 21, which can improve the space utilization of the battery rack 1, so that the battery swap station can accommodate more batteries.

[0112] (1) Before the battery replacement of the vehicle to be replaced begins, the battery connection device 4 (taking the stacker as an example) takes out a fully charged battery 7 and waits. After the battery replacement starts, the vehicle to be replaced is lifted to a certain height, the battery replacement robot 3 moves horizontally to the bottom of the vehicle to be replaced and disassembles the low-charged battery 6, and then the battery replacement robot 3 carries the low-charged battery 6 to the battery rack 1 and enters the accommodating space 13, and lifts the low-charged battery 6 through the avoidance space between the two second support plates 232 and the avoidance space between the two first support plates 231. At this time, the low-charged battery 6 is located above the first cache position.

[0113] (2) The two first support plates 231 of the battery cache device 2 are extended under the drive of the first telescopic driving mechanism 281 .

[0114] (3) The battery-swapping robot 3 descends, and the first cache position and the second cache position rise driven by two hydraulic cylinders. At this time, the first cache position carries the low-power battery 6.

[0115] (4) The battery docking device 4 docks with the second cache position, and controls the fork to extend to transport the fully charged battery 7 to the top of the second cache position.

[0116] (5) The battery docking device 4 descends, and the two second support plates 232 of the battery cache device 2 are extended under the drive of the second telescopic driving mechanism 282. At this time, the second cache position carries the fully charged battery 7.

[0117] (6) The fork of the battery docking device 4 retracts, the battery swapping robot 3 rises and carries the fully charged battery 7, then the two second support plates 232 of the battery cache device 2 retract under the drive of the second telescopic drive mechanism 282, and the battery swapping robot 3 carries the fully charged battery 7 and moves horizontally to the bottom of the vehicle to be replaced to install the fully charged battery 7.
