Description

Technical Field

[0001] The utility model relates to a battery swap station, in particular to a heavy truck battery swap station. Background Art

[0002] With the gradual popularization and rapid development of electric vehicles, the electrification trend of automobiles has become more and more obvious. Among them, the emergence of heavy-duty truck swap stations has solved the problems of slow charging and relieved charging anxiety, and improved the utilization rate of electric heavy-duty trucks and the driver's experience.

[0003] Most of the existing battery swapping methods in battery swapping stations are single-track and fork-side lifting battery swapping methods, such as China Patent No. CN218877200U, a side-swap lifting type battery swapping station for new energy heavy-duty trucks, CN218876954U, a side-swap lifting type heavy-duty truck battery swapping station, and CN116039574A, a dual-channel battery swapping station battery swapping method.

[0004] The monorail design means that the battery swap station can only perform cyclic battery swapping, that is, a single device first unloads the depleted battery pack from the battery compartment of the heavy truck and then lifts the fully charged battery pack onto the heavy truck. The battery swap cycle time of the battery packs at different charging stations in the entire station varies significantly, making it inconvenient to compile statistics on the battery swap data. At the same time, it will cause a series of problems due to the differentiated battery swapping experience, and the overall battery swapping efficiency needs to be further improved. Summary of the invention

[0005] The utility model aims at the problems existing in the heavy-duty truck swap station in the prior art and provides a double-guide rail linkage type heavy-duty truck swap station.

One end of the battery swap box extends to the rear end face of the battery pack deployment box along the width direction, and a plurality of columns are arranged on the lower end face of the other end. The columns form a vehicle walking channel with a length direction parallel to the length direction of the battery pack deployment box. The advantage of the battery swap channel being parallel to the vehicle body is retained, which can reduce the manufacturing and construction costs of the entire station.

[0011] Preferably, the battery pack storage cavity is provided with a plurality of battery trays for placing the battery packs, which are arranged in sequence along the length direction of the battery pack deployment track. The battery trays can realize the placement and charging of the battery packs.

[0012] Preferably, the battery pack translation mechanism includes a slide rail arranged along the length direction of the battery pack deployment track, the slide rail is slidably connected to the battery bracket, and also includes a transmission mechanism for realizing the linear reciprocating motion of the battery bracket along the slide rail. The sliding cooperation between the slide rail and the battery bracket can realize the stable operation of the battery pack translation, and also plays a role in positioning and guiding the battery bracket.

The servo motor drives the battery bracket to reciprocate on the guide rail through the chain system, thereby realizing battery transmission between the battery allocation robot system and the battery replacement robot system.

[0014] Preferably, the battery pack storage and transport box is provided with an air inlet, and the battery pack deployment box is provided with an air exhaust outlet.

[0015] Preferably, the end face of the battery pack deployment box away from the battery exchange box is provided with a battery deployment robot installation entrance, and the end face of the battery pack storage and transportation box away from the battery exchange box is provided with an inspection door. The arrangement of the battery deployment robot installation entrance and the inspection door can facilitate the inspection of the battery deployment robot and the internal components of the battery pack storage and transportation box.

[0016] Preferably, an electric cabinet door is provided on the battery pack storage and transportation box at a position opposite to the vehicle walking passage, and a battery swap station electric cabinet is provided on the inner side of the electric cabinet door in the battery pack transportation cavity.

[0017] Preferably, the battery pack deployment robot includes a first lifting fixture, which can move along the height direction of the battery pack deployment track.

[0018] Preferably, the battery swap robot includes a second lifting fixture, which can move along the length direction of the battery pack adjustment track and the height direction of the battery pack adjustment track.

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. Example 1

[0028] A double-rail linkage heavy truck swap station, such as Figure 1-Figure 6As shown, it includes a battery swap station body, in which a battery pack deployment track 106, a battery pack storage and transfer cavity 107 and a battery swap track 105 whose length direction is perpendicular to the length direction of the battery pack deployment track 106 are arranged, and the battery pack storage and transfer cavity 107 includes a battery pack storage cavity 108 arranged below the battery pack deployment track 106 and a battery pack transfer cavity 109 extending from one end of the battery pack storage cavity 108 along the length direction of the battery pack deployment track 106 to the lower part of the battery swap track 105;

[0029] A battery pack transfer chamber 109 is provided with a battery pack translation mechanism 10 for realizing translation of the battery pack in the length direction of the battery pack deployment track 106;

[0030] A battery pack deployment robot 7 for transferring battery packs between the battery pack storage cavity 108 and the battery pack translation mechanism 10 is provided on the battery pack deployment track 106; a battery exchange robot 6 for transferring battery packs between the battery pack translation mechanism 10 and the heavy truck battery compartment is provided on the battery exchange track 105.

[0031] In this embodiment, the battery pack deployment robot 7 includes a first lifting fixture 701, which can move along the height direction of the battery pack deployment track 106. The battery swap robot 6 includes a second lifting fixture 601, which can move along the length direction of the battery pack deployment track 106 and the height direction of the battery pack deployment track 106. The specific movement structure of the lifting fixture can be realized by adopting the existing structure of the existing lifting robot, which can realize the clamping, transportation and disassembly and assembly of the battery pack on the truck battery compartment. In addition, when the battery pack is hoisted at the battery swap station, it can also be operated across the battery pack in the height direction.

[0032] In this embodiment, dual guide rails are configured to realize the independent operation of two sets of mature ceiling-mounted battery-swapping robots 6. At the same time, a battery pack translation mechanism 10 is set between the two sets of battery-swapping robots 6 for linkage use, thereby realizing the organic separation of the battery pack charging, battery pack transportation and battery replacement processes of the battery swap station. The various parts can cooperate with each other and move synchronously, greatly shortening the actual battery replacement time and the overall working time of the battery swap station.

[0033] For truck drivers, the battery replacement time is the process of the battery replacement robot 6 taking the battery pack from the truck battery compartment and placing it on the battery pack translation mechanism 10 and transferring the fully charged battery pack 801 from the battery pack translation mechanism 10 to the truck battery compartment. This process is not affected by the location of the battery pack station, and can achieve basically the same battery replacement time for battery packs at different charging stations throughout the station, without causing a series of problems caused by differentiated battery replacement experience. At the same time, the basically consistent battery replacement time also makes it convenient for managers to compile statistics on battery replacement data.

[0034] In addition, the present application uses a top-mounted battery-changing robot 6. Compared with the fork-side top-mounted battery-changing, it solves the problems of the fork-side top-mounted battery-changing, such as the relatively expensive fork, the rapid wear of the fork cantilever when overloaded and used frequently, the lack of durability, and the poor repairability.

[0035] In this embodiment, the battery swap station body includes a battery pack deployment box 1, a battery pack storage and transportation box 2 arranged below the battery pack deployment box 1, and a battery swap box 3 arranged on the same horizontal plane as the battery pack deployment box 1. One end of the battery swap box 3 extends to the rear end surface of the battery pack deployment box 1 along the width direction, and a plurality of columns 5 are provided on the lower end surface of the other end. A vehicle walking passage 11 is formed between the columns 5, and the length direction of the vehicle walking passage 11 is parallel to the length direction of the battery pack deployment box 1.

[0036] The overall layout of the battery swap station in this embodiment is reasonable, which can realize the organic combination of the battery pack deployment box 1 and the battery swap box 3, thereby ensuring the mutual coordination between the internal battery pack deployment robot 7 and the battery swap robot 6 and the battery pack translation mechanism 10, and retaining the advantage of the battery swap channel being parallel to the vehicle body. The manufacturing and construction costs of the entire station are reduced accordingly, and the reliability is guaranteed, which is more conducive to the promotion of battery swap stations.

[0037] In this embodiment, the battery pack storage cavity 108 is provided with a plurality of battery trays 9 for placing battery packs, which are arranged in sequence along the length direction of the battery pack deployment track 106. The battery tray 9 is provided with a connector, which can realize charging of the battery pack on the battery tray 9, and the connector adopts a side outlet method, which can reduce the height space occupied by the tray and reduce the height of the entire station.

[0038] In this embodiment, the battery pack translation mechanism 10 includes a slide rail 1004 arranged along the length direction of the battery pack allocation track 106, and a battery bracket 1005 is slidably connected to the slide rail 1004, and also includes a transmission mechanism for realizing a linear reciprocating motion of the battery bracket 1005 along the slide rail 1004.

[0039] Among them, the transmission mechanism includes a bidirectional servo motor 1001 arranged at one end of the battery pack translation mechanism 10, and both sides of the bidirectional servo motor 1001 are connected to a transmission shaft 1002 whose length direction is arranged along the width direction of the battery pack allocation track 106. The ends of the two transmission shafts 1002 are provided with a driving sprocket 1003, and also include two driven sprockets 1007 arranged at the other end of the battery pack translation mechanism 10, and a chain 1006 for driving the battery bracket 1005 to perform linear reciprocating motion along the slide rail 1004 is connected between the corresponding driving sprocket 1003 and the driven sprocket 1007.

[0040] The battery bracket 1005 is connected to the chain 1006, and then the servo motor drives the battery bracket 1005 to reciprocate on the guide rail through the chain 1006 system, thereby realizing the battery transmission between the battery deployment robot system and the battery replacement robot 6 system.

[0041] In this embodiment, the battery pack storage and transportation box 2 is provided with an air inlet 101, and the battery pack distribution box 1 is provided with an air outlet 102. The end face of the battery pack distribution box 1 away from the battery exchange box 3 is provided with a battery distribution robot installation entrance 104, and the end face of the battery pack storage and transportation box 2 away from the battery exchange box 3 is provided with an inspection door 103. An electric cabinet door 4 is provided on the battery pack storage and transportation box 2 at a position opposite to the vehicle walking channel 11, and a battery pack transfer chamber 109 is provided with a battery exchange station electric cabinet 401 arranged on the inner side of the electric cabinet door 4, and the electric cabinet door 4 opens outward and is locked.

[0042] In this embodiment, the battery replacement process of the battery replacement station is completed by the linkage of three systems that can operate independently: the battery replacement robot 6 system, the battery deployment robot system and the battery translation system.

[0043] Among them, the battery swap robot 6 system only runs between the battery swap channel and the battery translation mechanism. The running distance is short and the distance of each battery swap is fixed. The distance of each battery swap is equivalent to the battery swap of the battery pack at the front-end workstation of the existing battery swap station, with the shortest distance and the shortest time.

[0044] The battery deployment robot system does not directly participate in the battery replacement process. It only hoists the fully charged battery pack onto the battery translation mechanism according to the system instructions, and then hoists the low-charged battery pack on the battery translation mechanism onto the idle battery base 9. This process also runs independently.

[0045] The battery translation mechanism is responsible for transferring fully charged and low-charged battery packs between the 6 battery swap robot 6 system and the 7 battery allocation robot system. It does not directly participate in the battery swap process and is also an independently operated system.

[0046] The three are linked and operated in an optimal mode through program control, that is, the system ensures that the battery-swapping robot 6 system can place the low-charged battery pack 802 at the first opportunity, and then lift the fully-charged battery pack 801.

[0047] In this embodiment, the system is operated at full load, that is, a sufficient number of battery packs are configured, so that the battery swap station can serve more vehicles for battery swaps, and the increased cost is only the increase in the length of the battery compartment.

[0048] The charger used in the battery swap station in this embodiment can be a separate outdoor cabinet charger, that is, one charger corresponds to one battery pack, or a flexible charging stack can be used, which can be selected according to different usage scenarios.

[0049] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0050] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
