Description

Technical Field

[0001] The present invention relates to the technical field of battery swap station construction, and in particular to a tunnel-type battery swap station suitable for hoisted battery swap vehicles. Background Art

[0002] Lithium-ion batteries and new energy electric vehicles have gradually matured in the past decade and have developed rapidly in my country. Electricity is the main alternative energy source for future automobile transportation, because it can be converted from a variety of clean and renewable energy sources such as solar energy, hydropower, wind energy and nuclear energy, and can also reduce the country's dependence on non-renewable energy such as oil. As people pay more attention to the concepts of environmental protection, low-carbon economy and reducing energy consumption, the automobile industry faces increasingly severe challenges due to its exhaust emissions, high energy consumption and other negative effects. Compared with traditional fuel vehicles, new energy vehicles can effectively reduce automobile exhaust pollution. From an environmental perspective, the exhaust emissions of new energy vehicles can be reduced by 92%-98% compared with traditional vehicles, thereby realizing the diversification of transportation energy and protecting the environment; from an energy perspective, the global oil crisis is becoming increasingly serious, and the automobile industry is the largest component of energy consumption. The development and use of new energy vehicles effectively solves the problem of heavy transportation energy consumption and achieves sustainable development of a low-carbon economy.

[0003] In recent years, both the national and local governments have clearly encouraged and supported the promotion and use of new energy vehicles. The 2014 Government Work Report once again clearly proposed "promoting new energy vehicles", insisting on the national strategy of developing new energy vehicles, the main strategic orientation of pure electric drive for the development of new energy vehicles and the transformation of the automobile industry, the development goals determined by the plan, and the policy orientation of government support.

[0004] Energy replenishment for new energy electric vehicles can be divided into two modes: plug-in charging and battery replacement. In the plug-in charging mode, there are three main problems: high initial cost of purchasing batteries, long charging time, and low charging safety. In addition, in the plug-in charging mode, the charging load of new energy electric vehicles has significant temporal and spatial randomness, which will have an adverse impact on the operation and planning of the power grid. The battery replacement mode combined with large-scale centralized charging has become another competitive business technology model for the current development of electric vehicles. First, this mode can effectively reduce the energy replenishment time of electric vehicles. Second, this mode can centrally manage charging safety and ensure the safety and reliability of the battery system. Third, through a reasonable business operation model and the use of battery leasing, business costs can be effectively controlled, and the traceability of the battery system can be centrally and effectively controlled. Depending on the type of vehicle, the general locations where replaceable battery packs are installed are under the chassis (passenger cars such as sedans and SUVs), on the side / rear of the frame, and above the frame (buses, trucks, mining machinery heavy vehicles, etc.). Different installation methods have different battery replacement methods. For example, the lower chassis generally adopts the bottom lifting type battery replacement, the side / rear of the frame generally adopts the side plug-in type battery replacement, and the upper frame generally adopts the hoisting type battery replacement. The side plug-in type battery replacement and the hoisting type battery replacement are applicable to different scenarios and have their own advantages and disadvantages. Generally speaking, the side plug-in type battery replacement vehicle has a compact structure and the construction investment of the battery replacement station is relatively low; the hoisting type battery replacement vehicle has a strong ability to pass through harsh road conditions and the mechanical investment of the battery replacement station is relatively low.

[0005] For hoisting-type battery swap stations, since the battery packs are lifted by a mechanical device similar to a crane, and the crane is installed on the supporting structure of the battery swap station, the strength requirements for the building foundation and the ground structure are relatively high. At the same time, due to the problem of lifting height, the ground building of the battery swap station is also relatively high. Therefore, the construction cost of the battery swap station is very high, accounting for more than half of the total investment. Although the requirements for mechanical docking accuracy are lower for hoisting-type battery swaps than for side plug-in battery swaps, and therefore the equipment investment cost is lower, the overall investment in the battery swap station is basically the same considering the higher construction cost. How to reduce construction costs is the key point to improve the economy of hoisting-type battery swap stations. At the same time, due to the high lifting height, the battery swap area is a dangerous operation area, and theoretically there is a risk of falling from a high altitude. If the battery pack falls from a high altitude, it may cause a fire risk.

[0006] Therefore, how to significantly reduce the civil construction cost of the battery swap station and reduce the risk of falling from heights without basically changing the original electrical and mechanical equipment selection is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems in the related art to a certain extent, and provides a tunnel-type battery swap station suitable for hoisted battery swap vehicles. On the basis of basically not changing the original electrical and mechanical equipment scheme selection, the construction cost of the battery swap station is reduced by about 60% by saving foundation workload, steel usage and other costs, and the lifting height of the battery pack during battery swapping is reduced, which greatly reduces the risk of personal accidents and fires after the battery pack falls accidentally.

[0008] In view of this, the present invention proposes a tunnel-type battery swap station suitable for hoisted battery swap vehicles, including a supporting structure, a driving beam, a driving device, a charging seat, a battery pack and a recessed driving lane; wherein, the driving beam is arranged above the supporting structure, the driving device is slidably arranged on the driving beam, the charging seat is arranged on the horizon between the supporting structures and is located below the driving beam, the battery pack completes the charging operation on the charging seat, and the driving device performs the picking and placing operations on the battery pack; the recessed driving lane is arranged between the supporting structures and is located below the driving beam.

[0009] The aforementioned tunnel-type battery swap station suitable for hoisted battery swap vehicles has a sunken drivingway with the horizon as the plane, and a tunnel-type parking platform dug downward to accommodate the battery swap vehicles.

[0010] The aforementioned tunnel-type battery swap station suitable for hoisted battery swap vehicles has a sunken carriageway of a ship-shaped structure including gentle slope sections at both ends and a platform section between the gentle slope sections; the distance from the deepest platform section of the sunken carriageway to the horizon is 3-4 meters, and the slope of the gentle slope section is less than 20%.

[0011] In the present invention, the width of the sunken carriageway is the vehicle width + 1m, and the slope of the sunken carriageway meets the requirements of the vehicle climbing without load.

[0012] The aforementioned tunnel-type battery swap station suitable for hoisted battery swap vehicles has drainage ditches dug on both sides of the bottom of the sunken carriageway, and a drainage system is set up in the drainage ditch.

[0013] The drainage system of the present invention at least includes a backup water pump to perform drainage operations when necessary.

[0014] The aforementioned tunnel-type battery swap station suitable for hoisting-type battery swap vehicles has an automatic lifting platform set in the sunken driving lane. The battery swap vehicle is parked on the automatic lifting platform and is lifted up and down in the sunken driving lane.

[0015] For the aforementioned tunnel-type battery swap station suitable for hoisted battery swap vehicles, the height of the charging seat shall not be lower than the roof height of the battery swap vehicle when the battery swap vehicle enters the bottom of the sunken lane.

[0016] For the aforementioned tunnel-type battery swap station suitable for hoisting-type battery swap vehicles, the height of the driving beam is at least the sum of the height of the charging seat from the horizon, the height of the bottom of the driving device from the driving beam and the height of the battery pack.

[0017] The aforementioned tunnel-type battery swap station suitable for hoisted battery swap vehicles, the supporting structure includes an upper structure support frame based on the horizon and a lower structure foundation based on the horizon, and the foundation is arranged below the support frame; the support frames are divided into several pieces, which are symmetrically arranged around the running beam.

[0018] Through the above technical scheme, the present invention proposes a tunnel-type battery swap station suitable for hoisting-type battery swap vehicles, which has the following technical effects:

[0019] 1. Without changing the original electrical and mechanical equipment selection, the construction cost is greatly reduced. By saving foundation work, steel usage and other costs, the construction cost of the battery swap station is reduced by about 60%.

[0020] 2. The lifting height of the battery pack during battery replacement is reduced, which greatly reduces the risk of personal accidents and fires caused by the battery pack falling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0028] Example 1

[0029] like Figure 1 , provides an existing solution for a battery swap station suitable for hoisting battery swap vehicles, including a supporting structure, a driving beam 8, a driving device 7, a charging seat 4, and a battery pack 6; wherein the driving beam 8 is arranged above the supporting structure, the driving device 7 is slidably arranged on the driving beam 8, the charging seat 4 is arranged on the horizon 5 between the supporting structures, and is located below the driving beam 8, the battery pack 6 completes the charging operation on the charging seat 4, and the driving device 7 performs the pick-and-place operation on the battery pack 6. For the existing solution, for example, the top height of a heavy-duty vehicle is generally more than 4 meters, and the height after lifting the battery pack 6 generally reaches more than 6 meters. Considering the length of the driving device 7, the driving beam 8 is generally about 7 meters high, and the supporting structure and the corresponding foundation 1 need to be designed according to the corresponding height. In addition, considering the need for the driving device 7 to reduce the swing amplitude of the steel cable, the length of the steel cable must be controlled within a certain range, so the height of the charging seat 4 also needs to be correspondingly too high to about 2 meters.

[0030] Example 2

[0031] like Figure 3 This embodiment proposes a tunnel-type battery swap station suitable for hoisting-type battery swap vehicles, including a supporting structure, a driving beam 8, a driving device 7, a charging seat 4, a battery pack 6 and a recessed driving lane 2; wherein, the driving beam 8 is arranged above the supporting structure, the driving device 7 is slidably arranged on the driving beam 8, the charging seat 4 is arranged on the horizon 5 between the supporting structures, and is located below the driving beam 8, the battery pack 6 completes the charging operation on the charging seat 4, and the driving device 7 performs the picking and placing operation on the battery pack 6; the recessed driving lane 2 is arranged between the supporting structures and is located below the driving beam 8.

[0032] The sunken lane 2 in this embodiment is a pit-type parking platform that is dug downward with the horizon 5 as the plane to accommodate the battery-swapping vehicle 10. It can be further understood that the sunken lane 2 is a ship-shaped structure including gentle slope sections at both ends and a platform section between the gentle slope sections; the deepest height of the sunken lane 2 is 3-4 meters, and the slope of the gentle slope section is less than 20%, which meets the vehicle's unloaded climbing requirements. The width of the sunken lane 2 is the width of the vehicle + 1m, where the vehicle width does not exceed 3m according to regulations, and the width of the sunken lane 2 is about 4m.

[0033] After the battery swap vehicle 10 enters the sunken lane 2, its height is significantly reduced, so the overall height of the battery swap station will be greatly reduced. As the height is reduced, the weight of the ground building, the rigidity of the system, and the wind resistance requirements will all decrease, the amount of steel used can be reduced by more than 70%, the investment in the foundation 1 will also be greatly reduced, and the construction cost of the charging station 4 will also be compressed.

[0034] To further optimize this embodiment, drainage ditches 3 are dug on both sides of the bottom of the sunken carriageway 2, and a drainage system is set in the drainage ditches 3. In this embodiment, the drainage system can be understood to include at least a backup water pump 11 to perform drainage operations when necessary. It is understood that in order to ensure drainage in rainy and snowy weather, drainage ditches 3 are dug on both sides of the sunken carriageway 2, and a backup water pump 11 is set to perform drainage operations when necessary.

[0035] To further optimize this embodiment, the height of the charging seat 4 is not lower than the roof height of the battery swapping vehicle 10 when the battery swapping vehicle 10 enters the bottom of the sunken driving lane 2. Furthermore, the height of the driving beam 8 is at least the sum of the height of the charging seat 4 from the horizon and the height of the bottom of the driving device 7 from the driving beam 8.

[0036] The supporting structure can be understood as including a superstructure supporting frame 9 based on the horizon 5 and a substructure foundation 1 based on the horizon 5, and the foundation 1 is arranged below the supporting frame 9; the supporting frames 9 are divided into several pieces, which are symmetrically arranged around the traveling beam 8.

[0037] Example 3

[0038] This embodiment proposes a tunnel-type battery swap station suitable for hoisting-type battery swap vehicles, including a supporting structure, a driving beam 8, a driving device 7, a charging seat 4, a battery pack 6 and a recessed driving lane 2; wherein, the driving beam 8 is arranged above the supporting structure, the driving device 7 is slidably arranged on the driving beam 8, the charging seat 4 is arranged on the horizon 5 between the supporting structures, and is located below the driving beam 8, the battery pack 6 completes the charging operation on the charging seat 4, and the driving device 7 performs the picking and placing operation on the battery pack 6; the recessed driving lane 2 is arranged between the supporting structures and is located below the driving beam 8.

[0039] The sunken lane 2 in this embodiment is a pit-type parking platform that is dug downward with the horizon 5 as the plane to accommodate the battery swap vehicle 10. It can be further understood that an automatic lifting platform is set in the sunken lane 2, and the battery swap vehicle 10 is parked on the automatic lifting platform, and is lifted up and down in the sunken lane 2; the deepest height of the sunken lane 2 is 3-4 meters. The width of the sunken lane 2 is the width of the vehicle + 1m, where the width of the vehicle does not exceed 3m according to regulations, and the width of the sunken lane 2 is about 4m.

[0040] Compared with Example 2, this embodiment uses an automatic lift to sink the vehicle, avoiding the need to repair a long ramp, which has certain advantages for scenes with tight land use. The height of the battery swap vehicle 10 is significantly reduced after entering the sunken lane 2, so the overall height of the battery swap station will be greatly reduced. As the height is reduced, the weight of the ground building, the rigidity of the system, and the wind resistance requirements will all decrease, the amount of steel used can be reduced by more than 70%, the investment in the foundation 1 will also be greatly reduced, and the construction cost of the charging station 4 will also be compressed.

[0041] To further optimize this embodiment, drainage ditches 3 are dug on both sides of the bottom of the sunken carriageway 2, and a drainage system is set in the drainage ditches 3. In this embodiment, the drainage system can be understood to include at least a backup water pump 11 to perform drainage operations when necessary. It is understood that in order to ensure drainage in rainy and snowy weather, drainage ditches 3 are dug on both sides of the sunken carriageway 2, and a backup water pump 11 is set to perform drainage operations when necessary.

[0042] To further optimize this embodiment, the height of the charging seat 4 is not lower than the roof height of the battery swapping vehicle 10 when the battery swapping vehicle 10 enters the bottom of the sunken driving lane 2. Furthermore, the height of the driving beam 8 is at least the sum of the height of the charging seat 4 from the horizon, the height of the bottom of the driving device 7 from the driving beam, and the height of the battery pack 6.

[0043] The supporting structure can be understood as including a superstructure supporting frame 9 based on the horizon 5 and a substructure foundation 1 based on the horizon 5, and the foundation 1 is arranged below the supporting frame 9; the supporting frames 9 are divided into several pieces, which are symmetrically arranged around the traveling beam 8.
