Description

Technical Field

[0001] The present invention belongs to the technical field of new energy battery swap stations, and in particular relates to a ceiling-mounted new energy vehicle battery swap station. Background Art

[0002] Charging and swapping stations are energy stations that provide charging and quick replacement of power batteries for electric vehicles. The current new energy market is flourishing, with more and more applicable vehicle models, and the designs of swapping stations for different models are also different.

[0003] The present invention is based on considerations of existing new energy trucks. Conventional new energy truck batteries are usually located on a vehicle frame behind the front of the truck. In order to meet the power consumption of the truck, the batteries thereon are characterized by being long and flat, and are usually designed in a rectangular shape that is almost the same width as the vehicle body and almost the same height as the front of the truck.

[0004] For example, a Chinese patent with publication number CN116062600A discloses a battery swap station with flexible and adaptive battery size, including a battery swap mechanism and a charging seat; the battery swap mechanism includes a mobile carriage, in which a wire rope drum is provided, and the wire rope output by the wire rope drum is connected to a sling; the sling is a sling that can adapt to battery packs of different specifications; the charging seat is a charging seat that can adapt to battery packs of different specifications, and by arranging a horizontal adjustment mechanism in the sling and the charging seat, the limit blocks and alignment blocks that play a positioning role can be adjusted in time according to the size parameters of the battery pack, thereby meeting the use requirements of the battery swap site where battery packs of different sizes and specifications are mixed.

[0005] The above patent shows a battery swap station, and also shows a layout plan of the battery swap station, that is, the battery compartment is arranged with the length direction of the battery compartment perpendicular to the running direction of the vehicle, and the battery can be replaced by driving the lifting device through a mobile crane that can move on the horizontal X-axis and the horizontal Y-axis. However, the battery swap station with this layout will take up a large space in terms of use effect. Therefore, there is another layout method in the industry, that is, the battery compartment is arranged with the length direction of the battery compartment perpendicular to the running direction of the vehicle, such as the patent with publication number CN113400993A A Chinese patent discloses a centralized heavy-duty truck battery swap station, including a main compartment of the battery swap station, a movable semi-hanging carrier connected to the outside of the main compartment of the battery swap station, and a cache battery compartment arranged inside the main compartment of the battery swap station. A number of heavy-duty truck battery swap battery packs are arranged in parallel in the cache battery compartment. For this type of battery swap station, since the battery will release heat during the charging process, for such a long and tall battery, the parallel storage scheme of the above scheme will cause the main heat release surfaces of the battery to be arranged relatively, which will cause fire safety hazards in the entire battery swap station.

[0006] Based on the problems that the above two types of battery swap stations have when dealing with such long, flat and tall large batteries, the present invention makes further designs to improve the above problems. Summary of the invention

[0035] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0036] Embodiment 1:

[0037] See also Figure 1-Figure 5 , a top-mounted new energy vehicle battery replacement station, comprising a centering mechanism, a battery replacement mechanism 1 2, a battery cache mechanism 3, a battery replacement mechanism 2 4 and a battery compartment 1;

[0038] The direction in which the vehicle drives to the centering mechanism is consistent with the length direction of the battery compartment 1, and the batteries 5 are arranged in the battery compartment 1 in such a manner that the length direction of the batteries is consistent with the length direction of the battery compartment 1, and the batteries are arranged in at most two rows in the width direction of the battery compartment 1;

[0039] The centering mechanism is used to align the front of the vehicle, and a conventional centering mechanism of a battery swap station can be used;

[0040] The battery replacement mechanism 2 includes a lifting and slinging device system 1 and a locking and unlocking mechanism 1 connected to the movable end of the lifting and slinging device system 1, and the lifting and slinging device system 1 slides on a ceiling rail 1 arranged along the width direction of the battery compartment 1;

[0041] The battery cache mechanism 3 includes a rotating platform 17 that can rotate at least 90° in the horizontal direction, and a battery placement tool 18 is arranged on the rotating platform 17. The rotating platform 17 can be controlled to rotate by a rotating motor;

[0042] The battery replacement mechanism 2 4 includes a lifting and slinging device system 2 and a locking and unlocking mechanism 2 connected to the movable end of the lifting and slinging device system 2, and the lifting and slinging device system 2 slides on a ceiling rail 2 6 arranged along the length direction of the battery compartment 1;

[0043] After the battery replacement mechanism 1 2 places the battery on the battery placement tool 18 on the rotating platform 17, the rotating platform 17 rotates so that the length direction of the battery thereon is consistent with the length direction of the battery compartment 1, and the battery replacement mechanism 2 4 is used to move the battery on the rotating platform 17 into the battery compartment 1 and move the battery in the battery compartment 1 onto the rotating platform 17, and the movement of the lifting and hoisting device system 1 and the lifting and hoisting device system 2 on the ceiling rail 1 and the ceiling rail 2 6 can be controlled by the motor;

[0044] In this embodiment, one of the overhead rail 1 and the overhead rail 2 6 is placed above the other and the height difference between the two is to ensure that the battery can pass between the two. After the battery replacement mechanism 1 places the battery on the battery placement tooling 18, the rotating platform 17 adjusts the length direction of the battery to be consistent with the length direction of the battery compartment 1, and then the battery placement mechanism 2 moves along the length direction of the battery compartment 1 and realizes the placement of the battery in the battery compartment 1 and the rotating platform 17. In this solution, the walls of the battery compartment 1 adjacent to the battery are all heat-dissipating structures or materials.

[0045] Embodiment 2:

[0046] Different from the first embodiment, the present embodiment limits the position of the battery placement tool 18 on the rotating platform 17 to a non-central position thereof, and the heights of the first and second overhead rails 6 are not limited. Figure 6 As shown, after the rotating platform 17 rotates, the position of the battery placement tool 18 can be transferred from the pick-up and placement path of the battery pick-up and placement mechanism 1 to the pick-up and placement path of the battery pick-up and placement mechanism 2.

[0047] Embodiment three:

[0048] Based on the implementation schemes of the previous two embodiments, the difference of this embodiment is that two battery placement fixtures 18 are symmetrically arranged on the rotating platform 17 with the rotating axis of the rotating platform 17 as the center. After this arrangement, before the vehicle replaces the battery, a battery can be placed on one of the battery placement fixtures 18 on the rotating platform 17 by the battery placement mechanism 2. After the battery placement mechanism 1 places the low-power battery taken from the vehicle on the other battery placement fixture 18, the fully charged battery on the rotating platform 17 can be taken, and then the rotating platform 17 is rotated and then replaced by the battery The picking and placing mechanism 2 takes away the deflated battery, and this process can effectively improve the efficiency of battery replacement. At the same time, since the battery placement tooling is symmetrically arranged on the center of the cache placement plate, after the battery picking and placing mechanism 1 puts down the deflated battery, it only needs to rise above the battery height and wait for the fully charged battery to turn around before it can be picked up. It should be noted that in the rope and chain type sling assembly 1, due to the influence of inertia during the horizontal movement, it is necessary to wait for the sling assembly 1 to stabilize before it can be lowered to ensure accuracy. The setting of this solution saves a lot of time in this part.

[0049] Embodiment 4:

[0050] Based on the previous three embodiments, the rotating platform 17 in this embodiment is placed on an AGV cart, and the AGV cart moves on a guide rail arranged along the length direction of the battery compartment 1. This is also a solution that can remove the height limit of the overhead rail 1 and the overhead rail 2 6. At the same time, in this solution, facing the rotating platform 17 with a single battery placement tool 18, the battery placement tool 18 can be optimized to be located at the center of the rotating platform 17 to reduce wear, and the position of the rotating platform 17 is adjusted by the AGV cart so that the batteries thereon can be placed on the battery pick-up and placement mechanism 1 and the battery pick-up and placement path of the battery pick-up and placement mechanism 2.
