[0011] In one embodiment, the locking element is a hydraulic cylinder or a pneumatic cylinder, and the first docking assembly further includes a mounting base with a through hole. The hydraulic cylinder or the pneumatic cylinder is connected to the mounting base, and the telescopic rod of the hydraulic cylinder or the pneumatic cylinder passes through the through hole.

[0014] The guide limiting component further includes a limiting block, which is elastically connected to the body and inclined relative to the body. The elastic force of the limiting block and the body is set along the inclined direction. The limiting block is provided with an abutment surface, which is located on the side of the limiting block near the second inclined surface and is parallel or nearly parallel to the second inclined surface. This surface is used to contact the second inclined surface when the battery swapping assembly is slid into the battery swapping bracket, so as to press the bottom bracket.

[0015] In one embodiment, the guide limiting member further includes a second fastener and a connecting structure extending from the body. The second fastener passes through the limiting block, and the limiting block is suspended on the connecting structure by the second fastener.

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] See Figures 1 to 4This application provides a battery swapping system in one embodiment, including a battery swapping bracket 200, a battery swapping assembly 100, and a first docking component 300. The battery swapping bracket 200 is connected to the vehicle body, and the battery swapping assembly 100 is slidably connected to the battery swapping bracket 200. During battery swapping, the battery swapping assembly 100 can slide into or out of the battery swapping bracket 200 under the action of external force, making battery swapping convenient and highly operable, enabling rapid battery swapping and reducing swapping time. The first docking component 300 is connected to the battery swapping bracket 200 and docks with the battery swapping assembly 100. When the battery swapping assembly 100 slides into the battery swapping bracket 200, the first docking component 300 can successfully dock with and lock with the battery swapping assembly 100, so that the battery swapping assembly 100 is reliably fixed, realizing the electrical connection and coolant circulation between the battery swapping assembly 100 and the vehicle body. Optionally, during battery swapping, the battery swapping assembly 100 can be manually or by means of a robotic arm to push and slide into the battery swapping bracket 200. When disassembling the battery swapping assembly 100, after unlocking the first docking component 300 from the battery swapping assembly 100, the battery swapping assembly 100 can be pulled manually or by a robotic arm to slide out of the battery swapping bracket 200. This battery swapping system offers convenient battery replacement, strong operability, time and labor saving, and high efficiency.

[0044] To facilitate the sliding of the battery swapping assembly 100 into or out of the battery swapping bracket 200, such as Figure 2 and Figure 3 As shown, in one embodiment, the battery swapping bracket 200 includes at least one sliding bracket 230, and the sliding bracket 230 is provided with at least one pulley 231. The pulley 231 makes rolling contact with the battery swapping assembly 100 to achieve a sliding connection between the battery swapping assembly 100 and the battery swapping bracket 200. Optionally, there may be one, two, three, or four sliding brackets 230, and each sliding bracket 230 is provided with one, two, three, or four pulleys 231. The axis of the pulley 231 is perpendicular or nearly perpendicular to the sliding direction of the battery swapping assembly 100. When there are multiple sliding brackets 230, they are evenly spaced apart; when there are multiple pulleys 231, they are evenly arranged on the sliding brackets 230 to increase the sliding contact area between the battery swapping assembly 100 and the battery swapping bracket 200, reduce sliding resistance, and facilitate pushing the battery swapping assembly 100 into or pulling it out of the battery swapping bracket 200.

[0045] The sliding bracket 230 can adopt any structural form, as long as it allows the pulley 231 to roll in contact with the battery swapping assembly 100 without interference. Optionally, the sliding bracket 230 can be a plate, rod, or planar frame structure.

[0046] To facilitate the interlocking of the first docking component 300 with the battery swapping component 100, such as Figures 2 to 5 As shown, in one embodiment, the first docking assembly 300 includes a locking member 340; the battery swapping assembly 100 further includes a battery pack and a second docking assembly 140 connected to each other. The second docking assembly 140 includes a mating member 141, which is disposed opposite to the locking member 340 and is perpendicular or nearly perpendicular to the sliding direction of the battery swapping assembly 100. The locking member 340 is configured to be able to pass through the mating member 141 under external force or to disengage from the mating member 141 under external force. When the locking member 340 passes through the mating member 141 under external force, it restricts the sliding of the battery swapping assembly 100 relative to the battery swapping bracket 200, thereby locking the battery swapping assembly 100 and the battery swapping bracket 200 together. When the locking member 340 disengages from the mating member 141 under the action of external force, the constraint on the battery swapping assembly 100 in the sliding direction is released, allowing the battery swapping assembly 100 to slide into or out of the battery swapping bracket 200, thereby unlocking the battery swapping assembly 100 from the battery swapping bracket 200.

[0047] Furthermore, in order to simultaneously lock the first docking component 300 and the battery swapping component 100 together, and fix both ends of the battery swapping component 100, in one embodiment, there are at least two locking members 340. Each locking member 340 has a moving end and a fixed end. The fixed end is fixedly connected to the first docking component 300. Every two locking members 340 form a pair, and the moving ends of each pair of locking members 340 are arranged in opposite directions. The number of mating members 141 is the same as the number of locking members 340. Every two mating members 141 form a pair. When the moving ends of the locking members 340 are all inserted through the mating members 141, the first docking component 300 and the battery swapping component 100 are locked together. In a direction parallel or nearly parallel to the locking members 340, both ends of the battery swapping component 100 are fixed, that is, the battery swapping component 100 cannot move left or right relative to the longitudinal beam of the vehicle body, which further improves the connection stability of the battery swapping component 100.

[0048] Optionally, in one embodiment, the locking member 340 is a hydraulic cylinder or a pneumatic cylinder. The first docking assembly 300 further includes a mounting base 330 with a through hole. The hydraulic cylinder or the pneumatic cylinder is connected to the mounting base 330, and the telescopic rod of the hydraulic cylinder or the pneumatic cylinder passes through the through hole. The mating member 141 has a locking hole, and the telescopic rod of the hydraulic cylinder or the pneumatic cylinder is configured to pass through the locking hole to lock the first docking assembly 300 and the battery swapping assembly 100 together. When the telescopic rod of the hydraulic cylinder or the pneumatic cylinder enters the locking hole, the first docking assembly 300 and the battery swapping assembly 100 are locked together. When the telescopic rod of the hydraulic cylinder or the pneumatic cylinder disengages from the locking hole, the first docking assembly 300 and the battery swapping assembly 100 are unlocked, and thereafter, the battery swapping assembly 100 can move relative to the battery swapping bracket 200. Locking or unlocking is achieved by controlling the movement of the telescopic rod with a hydraulic cylinder or the pneumatic cylinder, improving operability and facilitating control.

[0049] To facilitate sliding the battery swapping assembly 100 into the battery swapping bracket 200, such as Figure 4 and Figure 5 As shown, in one embodiment, the battery swapping assembly 100 further includes a bottom bracket 130. The bottom bracket 130 is connected to the battery pack and protrudes relative to the outer wall of the battery pack. The bottom bracket 130 is guided and limited by the battery swapping bracket 200. The battery pack is limited by the exposed portion of the bottom bracket 130 relative to the battery pack being connected to the battery swapping bracket 200. During the process of the battery swapping assembly 100 sliding into the battery swapping bracket 200, the exposed portion of the bottom bracket 130 guides the battery pack, allowing the battery swapping assembly 100 to slide smoothly into the battery swapping bracket 200.

[0050] Furthermore, such as Figures 3 to 6 As shown, in one embodiment, the bottom bracket 130 is provided with a first inclined surface 131 and an adjacent second inclined surface 132. The first inclined surface 131 is disposed on the side of the bottom bracket 130 near the battery pack, and the second inclined surface 132 is disposed on the side of the bottom bracket 130 near the first docking assembly 300 and / or away from the first docking assembly 300. The battery swapping bracket 200 further includes a guide limiting member 240, which includes a body and at least one guide portion. The guide portion is disposed on one side of the body and is used to contact the second inclined surface 132 when the battery swapping assembly 100 is slid into the battery swapping bracket 200. Through the cooperation of the guide portion and the second inclined surface 132, the battery swapping assembly 100 is guided as a whole, which facilitates the accurate positioning of the battery swapping assembly 100 and allows it to be smoothly locked with the first docking assembly 300 after sliding into the battery swapping bracket 200.

[0051] To achieve precise positioning of the battery swapping assembly 100 during battery swapping, optionally, at least two guide limiting members 240 are provided. Each pair of guide limiting members 240 is arranged on both sides of the inner wall of the battery swapping bracket 200. The guide portion includes a first guide portion 241, a second guide portion 242, and a third guide portion 243. The first guide portion 241 is inclined relative to the second guide portion 242. The second guide portion 242 is parallel or nearly parallel to the sliding direction of the battery swapping assembly 100. The third guide portion 243 is inclined relative to the second guide portion 242. The first guide portion 241 of each pair of guide limiting members 240 forms a coarse positioning channel, the second guide portion 242 of each pair of guide limiting members 240 forms a transition channel, and the third guide portion 243 of each pair of guide limiting members 240 forms a fine positioning channel. The diameter of the coarse positioning channel gradually increases in the direction away from the first docking component 300, allowing the second inclined surface 132 of the bottom bracket 130 of the battery swapping assembly 100 to enter the coarse positioning channel between the first guide portions 241 of each pair of guide limiters 240 during battery swapping, facilitating docking. The two side walls of the transition channel are parallel or nearly parallel to the two outer side walls of the bottom bracket 130, which can correct the posture of the battery swapping assembly 100 as it slides into the battery swapping bracket 200, preventing it from stopping due to a deviation in the sliding direction. The diameter of the fine positioning channel gradually decreases in the direction close to the first docking component 300, allowing the bottom bracket 130 to be further positioned and clamped by the fine positioning channel after the battery swapping assembly 100 slides into the battery swapping bracket 200, achieving precise positioning of the battery swapping assembly 100 and ensuring that it can be smoothly locked with the first docking component 300 after sliding into the battery swapping bracket 200.

[0052] Furthermore, to prevent the battery swapping assembly 100 from jumping or detaching from the battery swapping bracket 200 during the battery swapping operation, the guide limiting member 240 also includes a limiting block 244. The limiting block 244 is elastically connected to the body and is inclined relative to the body. The elastic force of the limiting block 244 and the body is set along the inclined direction. The limiting block 244 has an abutment surface 2441. The abutment surface 2441 is set on the side of the limiting block 244 near the first inclined surface 131 and is parallel or nearly parallel to the first inclined surface 131. This allows the battery swapping assembly 100 to contact the first inclined surface 131 when it is slid into the battery swapping bracket 200, thereby pressing the bottom bracket 130 and preventing the battery swapping assembly 100 from jumping or detaching relative to the battery swapping bracket 200.

[0053] Among them, such as Figure 6 , Figure 7 and Figure 8As shown, the guide limiting member 240 further includes a second fastener 249 and a connecting structure 245 extending from the body. The second fastener 249 passes through the limiting block 244, and the limiting block 244 is suspended on the connecting structure 245 by the second fastener 249. The guide limiting member 240 also includes an elastic member 246 and a sleeve 247. The elastic member 246 is stacked with the limiting block 244 and disposed between the limiting block 244 and the connecting structure 245. The sleeve 247 passes through the elastic member 246 and the limiting block 244 and is sleeved on the second fastener 249. One end of the sleeve 247 near the limiting block 244 is aligned with the inner wall of the limiting block 244. When the elastic member 246 is compressed, the other end of the sleeve 247 protrudes from the outer wall of the elastic member 246. When the battery swapping assembly 100 slides into the battery swapping bracket 200, the abutment surface 2441 of the limiting block 244 abuts against the first inclined surface 131 of the bottom bracket 130, pressing the bottom bracket 130 against the bottom of the battery swapping bracket 200. A flexible connection is achieved through the elastic element 246, allowing the bottom bracket 130 to smoothly slide into the battery swapping bracket 200 by engaging with the guide limiting member 240, preventing jamming. Optionally, the guide limiting member 240 further includes a first fastener 248 for fastening the second fastener 249 and the sleeve 247, simultaneously fixing their ends. Optionally, the second fastener 249 is a connecting pin, bolt, or screw, with the head of the connecting pin, bolt, or screw flush with the abutment surface 2441 of the outer wall of the limiting block 244, and the tail of the connecting pin, bolt, or screw fixedly connected to the first fastener 248. Optionally, the first fastener 248 is a nut.

[0054] To achieve lateral battery swapping, in one embodiment, such as Figure 2 and Figure 3 As shown, the battery swapping bracket 200 also includes a bottom frame 210 and a side frame 220. The bottom frame 210 is connected between the two side frames 220. The side frames 220 are connected to the vehicle body longitudinal beam 400. The bottom frame 210 is slidably connected to the battery swapping assembly 100, so that the battery swapping assembly 100 can slide into the battery swapping bracket 200 from the side away from the vehicle body longitudinal beam 400, which can realize lateral battery swapping, making battery swapping convenient and easy to operate.

[0055] To meet the needs of different vehicle models, optionally, such as Figure 3 As shown, there are two battery swapping brackets 200 and two battery swapping battery packs 100, with the two battery swapping brackets 200 respectively disposed on both sides of the vehicle body longitudinal beam 400. Figure 2As shown, the first docking assembly 300 further includes a first connecting frame 310 and a second connecting frame 320. There are two first connecting frames 310, and the second connecting frame 320 is connected between the two first connecting frames 310. The two first connecting frames 310 are respectively connected to the two battery swapping brackets 200, so that the two battery swapping battery assemblies 100 can slide into the two battery swapping brackets 200 from the side away from the vehicle longitudinal beam 400, realizing side battery swapping from both sides of the vehicle body. At the same time, it increases the power capacity and range, which can meet the needs of different vehicle models, such as commercial trucks and buses. For different user scenarios, different battery system solutions can be flexibly combined and matched to adapt to the actual use needs of users, avoid insufficient power or power waste, and improve economy.

[0056] In one embodiment, there are two locking members 340. The fixed end of the locking member 340 is fixedly connected to the first connecting frame 310 through the mounting base 300. Each pair of locking members 340 is a pair, and the moving ends of each pair of locking members 340 are arranged in opposite directions. When the moving ends of the locking members 340 are both inserted through the mating member 141, the first docking component 300 and the battery swapping assembly 100 are locked together. In the direction parallel or nearly parallel to the locking members 340, both ends of the battery swapping assembly 100 are fixed to improve the connection stability of the battery swapping assembly 100.

[0057] To increase the capacity of the battery swapping assembly 100, optionally, such as Figure 4 and Figure 5 As shown, the battery swapping assembly 100 includes at least one battery pack stacked together, and each battery pack contains a battery module 500. When there are two or more battery packs, the battery modules 500 are interconnected. Optionally, in one embodiment, the battery pack includes a first battery module 110 and a second battery module 120. The first battery module 110 has a first accommodating space, and the second battery module 120 has a second accommodating space. The first accommodating space and the second accommodating space are connected to each other to facilitate electrical connection and coolant circulation between the battery modules 500.

[0058] In some embodiments, such as Figure 3 As shown, the first docking assembly 300 also includes a vehicle-side battery swapping connector 350 and a vehicle-side liquid-cooled quick-connect connector 360. The vehicle-side battery swapping connector 350 is used to connect to the vehicle's high-voltage and low-voltage electrical systems, and the vehicle-side liquid-cooled quick-connect connector 360 is used to connect to the vehicle's cooling system. Figure 4As shown, the second docking assembly 140 further includes a battery-side liquid-cooled quick-connect connector 142 and a battery-side battery swapping connector 143. The battery-side liquid-cooled quick-connect connector 142 is connected to the battery pack and docks with the vehicle-side liquid-cooled quick-connect connector 360. The battery-side battery swapping connector 143 is connected to the battery pack and docks with the vehicle-side battery swapping connector 350, thereby realizing the electrical connection and coolant circulation between the battery swapping assembly 100 and the vehicle.
