Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, and in particular to an integrated battery pack and a vehicle. Background Art

[0002] At present, passenger car battery-swap models mainly use chassis battery swapping for battery swapping, but the existing battery pack is usually a whole battery pack, and with the gradual pursuit of vehicle range, the size of the battery pack is getting larger and larger, resulting in some battery-swap models being difficult to remove the battery pack from the chassis for battery swapping due to the large size of the battery pack and the limitation of the vehicle's wheelbase.

[0003] To address this issue, existing battery swap stations lift the vehicle and perform battery swaps beneath the chassis. Even with mobile battery swaps, the large battery pack size necessitates a larger mobile swap robot, requiring the vehicle to be lifted for battery swaps. Furthermore, lifting a vehicle outdoors is subject to environmental limitations. For example, some terrains are not suitable for lifting the vehicle, making battery swaps impossible. Utility Model Content

[0004] The problem solved by the utility model is: how to improve the convenience of vehicle battery replacement operation.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

The X-axis in the accompanying drawings represents the horizontal direction and is designated as the front-to-back position, with the positive direction of the X-axis representing the front side and the reverse direction of the X-axis representing the rear side. The Y-axis in the accompanying drawings represents the left-to-right position, with the positive direction of the Y-axis representing the left side and the reverse direction of the Y-axis representing the right side. It should also be noted that the aforementioned Z-axis, Y-axis, and X-axis are merely for the purpose of facilitating the description of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0024] The term "including" and its variations used in this document are open inclusions, that is, "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optionally" means "optional embodiments". The relevant definitions of other terms will be given in the following description. It should be noted that the concepts of "first", "second", etc. mentioned in this utility model are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0025] It should be noted that the modifications of "one" and "multiple" mentioned in the present invention are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0026] In the related art, the battery pack is usually a whole battery pack, and in the case of gradually pursuing the vehicle's cruising range, the size of the battery pack is getting larger and larger, resulting in some battery-swap models being unable to remove the battery pack from the chassis for battery swap when the vehicle is parked due to the large size of the battery pack and the limitation of the vehicle's wheelbase. In order to solve this problem, the existing battery swap station adopts the method of lifting the vehicle and swapping the battery under the chassis. Even if a mobile battery swap method is adopted, due to the large overall volume of the battery pack, the volume of the mobile battery swap robot also needs to be designed to be large, so the vehicle also needs to be lifted for battery swapping. Moreover, there are environmental conditions for lifting the vehicle outdoors. For example, some special terrains do not support lifting the vehicle, resulting in the inability to swap the battery. In addition, if the battery pack is partially damaged, the entire battery pack needs to be replaced, which is costly.

[0027] In response to the problems existing in the above-mentioned related technologies, the present utility model provides an integrated battery pack and a vehicle.

[0028] Combine Figure 1 and Figure 2 As shown, an integrated battery pack provided by an embodiment of the present invention includes a frame 1, multiple battery packs 2 and multiple first locking mechanisms 3. The multiple battery packs 2 are respectively connected to the frame 1 through multiple first locking mechanisms 3. The first locking mechanisms 3 are used to connect the corresponding battery packs 2 to the frame 1 to lock the corresponding battery packs 2, and to separate the corresponding battery packs 2 from the frame 1 to unlock the corresponding battery packs 2.

[0029] Specifically, the frame 1 serves as a carrier for the integrated battery pack, which is usually assembled from crossbeams, longitudinal beams and columns. The battery pack 2 serves as the main structure of the integrated battery pack, which mainly includes battery cells, connectors and shells, etc. Moreover, each battery pack 2 is installed in the internal space of the frame 1 through a first locking mechanism 3, that is, the number of first locking mechanisms 3 is the same as the number of battery packs 2. Among them, a part of the structure of the first locking mechanism 3 (such as the first lock body 311) is set on the frame 1, and the other part of the structure (such as the first lock buckle 312) is set on the battery pack 2, that is, the first locking mechanism 3 is set between the frame 1 and the battery pack 2; by connecting the first lock body 311 and the first lock buckle 312 of the first locking mechanism 3 to lock the battery pack 2 on the frame 1, and by separating the first lock body 311 and the first lock buckle 312 of the first locking mechanism 3 to unlock the battery pack 2, it is convenient to replace the battery. In other words, each battery pack 2 can be disassembled and assembled separately, thereby forming an independent battery replacement module. When battery replacement is required, the first locking mechanism 3 can be unlocked manually or electrically to separate the battery pack 2 from the frame 1, thereby removing the battery pack 2 for battery replacement. After the battery replacement is completed, the first locking mechanism 3 can be locked to fix the battery pack 2 that has completed the battery replacement on the frame 1. In addition, the integrated battery pack can be replaced at a battery replacement station, or it can be replaced on the move when the vehicle is parked. When replacing the battery at a battery replacement station, the vehicle can be lifted and the battery pack 2 that needs to be replaced can be removed from under the vehicle chassis for battery replacement. When replacing the battery on the move, the battery replacement robot 400 can be used to remove the battery pack 2 that needs to be replaced from under the vehicle body 100 for battery replacement.

[0030] The integrated battery pack in this embodiment can be provided with a plurality of first locking mechanisms 3, and a plurality of battery packs 2 are respectively connected to the frame 1 through the plurality of first locking mechanisms 3, so as to realize the integration of a plurality of battery packs 2 on the frame 1, so that the integrated battery pack can meet the high mileage requirement. When it is necessary to replace the battery, the first locking mechanism 3 can be unlocked to separate the battery pack 2 from the frame 1, so that the battery pack 2 can be removed for replacement. After the replacement is completed, the first locking mechanism 3 can be locked to fix the battery pack 2 that has completed the replacement on the frame 1. In this way, only the battery pack 2 that needs to be replaced can be replaced without replacing the entire integrated battery pack. This not only reduces maintenance costs, but also greatly improves the convenience of the battery replacement operation. At the same time, the battery replacement robot 400 only needs to adapt to a smaller battery pack 2, so that the volume of the battery replacement robot 400 can be reduced accordingly. In addition, when replacing the battery, the vehicle can be lifted at the battery replacement station or the battery pack 2 can be removed from the bottom of the vehicle body 100 by using the battery replacement robot 400 when the vehicle is parked. This allows the integrated battery pack to support both lifting and replacing at the battery replacement station and non-lifting and replacing during mobile battery replacement, thereby improving the flexibility of the battery replacement operation.

[0031] Optionally, combined Figure 1 As shown, a plurality of battery packs 2 are distributed on the frame 1 in rows and columns.

[0032] In this optional embodiment, the plurality of battery packs 2 are generally distributed on the frame 1 in the form of multiple rows and columns, for example, Figure 1 The example in Figure 1 shows an integrated battery pack including four battery packs 2, which are arranged in two rows and two columns on a frame 1. Compared with arranging multiple battery packs 2 in a single row or column, this can reduce the size of the integrated battery pack in the arrangement direction of the battery packs 2, thereby facilitating the layout of the integrated battery pack.

[0033] Optionally, the internal space of the frame 1 is divided into a plurality of accommodating cavities, and the plurality of battery packs 2 are respectively arranged in the plurality of accommodating cavities.

[0034] In this optional embodiment, the number of accommodating cavities on the frame 1 is consistent with the number of battery packs 2, and a first locking mechanism 3 is provided in each accommodating cavity. In this way, multiple battery packs 2 can be placed without affecting each other, thereby further improving the convenience of battery replacement. Moreover, compared with providing a larger cavity in the frame 1 to accommodate all battery packs 2, dividing the internal space of the frame 1 into multiple smaller accommodating cavities allows the middle portion of the entire frame 1 to have higher rigidity due to the provision of structures such as partition plates or partition beams, thereby ensuring the stability of the battery packs 2 installed and fixed on the frame 1.

[0035] Optionally, combined Figure 2 As shown, the first locking mechanism 3 is located between the bottom wall of the accommodating cavity and the battery pack 2 .

[0036] In this optional embodiment, the accommodating cavity has an opening, side walls and a bottom wall. The battery pack 2 is usually installed into the accommodating cavity from the opening of the accommodating cavity. The side walls of the accommodating cavity can limit the battery pack 2 to ensure that the battery pack 2 is installed firmly. The opening of the accommodating cavity is usually set downward, that is, the battery pack 2 is arranged in the up and down direction (i.e. Figure 2 The first locking mechanism 3 is provided between the bottom wall of the accommodating cavity and the battery pack 2, that is, the first locking mechanism 3 is located above the battery pack 2. In this way, each battery pack 2 is fixed to the frame 1 in a suspended manner. When the battery swapping robot 400 is used for mobile battery swapping, it is convenient for the battery swapping robot to remove a single battery pack 2 from the bottom of the battery pack 2 for battery swapping, thereby further improving the convenience of mobile battery swapping.

[0037] Optionally, combined Figure 3 As shown, the size of the battery pack 2 in the front-to-rear direction and / or the left-to-right direction of the vehicle is smaller than the minimum distance between the front wheels 200 and the rear wheels 300 of the vehicle in the front-to-rear direction.

[0038] It should be noted that the front and rear directions of the vehicle are Figure 1 The X-axis direction is referred to as the front-to-back direction, and the left-to-right direction of the vehicle is Figure 1 The middle Y-axis direction, referred to as the left and right direction.

[0039] Specifically, the battery pack 2 can be a circular structure. In this case, the dimensions of the battery pack 2 in the front-to-back direction and the left-to-right direction of the vehicle generally refer to the outer diameter of the battery pack 2. The battery pack 2 can also be a square structure. In this case, the dimensions of the battery pack 2 in the front-to-back direction and the left-to-right direction refer to the length and width dimensions of the battery pack 2. During mobile battery replacement, if the dimensions of a single battery pack 2 in the front-to-back direction are smaller than the minimum spacing between the front wheels 200 and the rear wheels 300, and the dimensions in the left-to-right direction are larger than the minimum spacing between the front wheels 200 and the rear wheels 300, the battery replacement robot 400 moved to the bottom of the battery pack 2 can first drive the battery pack 2 downward until it is completely separated from the frame 1, and then drive the battery pack 2 to move in the front-to-back direction to between the front wheels 200 and the rear wheels 300, and then drive the battery pack 2 in the left-to-right direction from the space between the front wheels 200 and the rear wheels 300 to the outside of the vehicle, thereby removing the battery pack 2; if the dimensions of a single battery pack 2 in the left-to-right direction are smaller than the dimensions of the front wheels 200 and the rear wheel 300, and the size in the front-to-back direction is greater than the minimum distance between the front wheel 200 and the rear wheel 300, then the battery-exchanging robot 400 moved to the bottom of the battery pack 2 can first drive the battery pack 2 to move downward until it is completely out of the frame 1, and then drive the battery pack 2 to move between the front wheel 200 and the rear wheel 300 in the front-to-back direction, and then rotate the battery pack 2 90° so that the smaller front or rear end of the battery pack 2 faces the space between the front wheel 200 and the rear wheel 300, and finally drive the battery pack 2 to move from the space between the front wheel 200 and the rear wheel 300 in the left-right direction to the outside of the vehicle, thereby removing the battery pack 2.

[0040] In this way, by designing the size of the battery pack 2 in the front-to-back direction and / or left-to-right direction of the vehicle to be smaller than the minimum distance between the front wheels 200 and the rear wheels 300 of the vehicle in the front-to-back direction, it is ensured that a single battery pack 2 can be taken out from the bottom of the left or right side of the vehicle, thereby further improving the convenience of mobile battery replacement.

[0041] Optionally, combined Figure 1 and Figure 2 As shown, the integrated battery pack also includes a second locking mechanism 4. The frame 1 is used to be connected to the vehicle body 100 through the second locking mechanism 4. The second locking mechanism 4 is used to connect the frame 1 to the vehicle body 100 to lock the frame 1, and to separate the frame 1 from the vehicle body 100 to unlock the frame 1.

[0042] In this optional embodiment, the second locking mechanism 4 is arranged between the frame 1 and the vehicle body 100, that is, a part of the structure of the second locking mechanism 4 (such as the second lock body 411) is arranged on the vehicle body 100, and the other part of the structure (such as the second lock buckle 412) is arranged on the frame 1. By connecting the second lock body 411 and the second lock buckle 412 of the second locking mechanism 4 to fix the frame 1 on the vehicle body 100, the integrated battery pack is fixed on the vehicle body 100, and by separating the second lock body 411 and the second lock buckle 412 of the second locking mechanism 4 to unlock the frame 1, the entire integrated battery pack can be easily replaced. In other words, the integrated battery pack can be disassembled and assembled as a whole, and can also be used as a battery replacement module. When the entire integrated battery pack is replaced, due to its large size, it is usually impossible to remove the entire integrated battery pack from the bottom of the vehicle body 100 without lifting it. Therefore, in actual applications, the vehicle is usually lifted for battery replacement. At this time, the second locking mechanism 4 can be unlocked manually or electrically to separate the frame 1 from the vehicle body 100, thereby removing the entire integrated battery pack for battery replacement. After the battery replacement is completed, the second locking mechanism 4 can be locked to fix the integrated battery pack that has completed the battery replacement on the vehicle body 100. In this way, the integrated battery pack can support both battery replacement of a single battery pack 2 and battery replacement of the entire battery pack, thereby improving the flexibility of the battery replacement operation.

[0043] Optionally, the first locking mechanism 3 includes a plurality of first quick-change lock structures 31 arranged between the frame 1 and the battery pack 2 , and / or the second locking mechanism 4 includes a plurality of second quick-change lock structures 41 arranged between the frame 1 and the vehicle body 100 .

[0044] In this optional embodiment, the first quick-change lock structure 31 and / or the second quick-change lock structure 41 can be a quick-change lock structure that uses a lock hook and a pawl to achieve locking and unlocking, or a quick-change lock structure that uses a spiral boss and a spiral groove to rotate and engage or separate to achieve locking and unlocking. In actual applications, when the battery pack 2 has a square structure, it is usually preferred that the first quick-change lock structure 31 and / or the second quick-change lock structure 41 is a quick-change lock structure that uses a lock hook and a pawl to achieve locking and unlocking. When the battery pack 2 has a circular structure, it is usually preferred that the first quick-change lock structure 31 and / or the second quick-change lock structure 41 is a quick-change lock structure that uses a spiral boss and a spiral groove to rotate and engage or separate to achieve locking and unlocking. In this way, not only can the firmness of the locking mechanism be ensured when locked, but also the efficiency and convenience of replacing a single battery pack 2 or the entire integrated battery pack can be improved. Furthermore, each first locking mechanism 3 includes multiple first quick-change lock structures 31, and each second locking mechanism 4 includes multiple second quick-change lock structures 41. The multiple first quick-change lock structures 31 are typically positioned around the upper edge of the battery pack 2, while the multiple second quick-change lock structures 41 are typically positioned around the upper edge of the frame 1. This ensures that each battery pack 2 is secured by the multiple first quick-change lock structures 31, and the entire frame 1 is secured by the multiple second quick-change lock structures 41, ensuring that both the individual battery packs 2 and the entire integrated battery pack are securely mounted.

[0045] Optionally, combined Figure 1 and Figure 2 As shown, a plurality of first quick-change plug-ins 11 are provided on the frame 1, and the plurality of first quick-change plug-ins 11 are respectively used to connect with the electrical connector of the entire vehicle, and the first quick-change plug-ins 11 are used to connect with the electrical connector on the corresponding battery pack 2 when the corresponding battery pack 2 is locked, and to separate from the electrical connector on the corresponding battery pack 2 when the corresponding battery pack 2 is unlocked.

[0046] Specifically, the number of first quick-change plug-ins 11 is consistent with the number of battery packs 2, and each battery pack 2 is provided with an electrical connector, and the first quick-change plug-in 11 is used to plug and match with the electrical connector on the corresponding battery pack 2. In addition, when the frame 1 is not provided with the second quick-change plug-in 12 described later, the multiple first quick-change plug-ins 11 are directly connected to the electrical connector of the entire vehicle. When the frame 1 is provided with the second quick-change plug-in 12, the multiple first quick-change plug-ins 11 are connected to the electrical connector of the entire vehicle through the second quick-change plug-in 12. When it is necessary to replace the battery of a single battery pack 2, the first locking mechanism 3 is unlocked to separate the battery pack 2 from the frame 1. At this time, the first quick-change plug-in 11 on the frame 1 is also separated from the electrical connector on the battery pack 2. After the battery replacement is completed, the first locking mechanism 3 is locked to lock the battery pack 2 on the frame 1. At this time, the electrical connector on the battery pack 2 is plugged and matched with the corresponding first quick-change plug-in 11, thereby connecting the high-voltage circuit of the battery pack 2, so that the battery pack 2 can supply power to the electrical components of the entire vehicle.

[0047] In this optional embodiment, by arranging a plurality of first quick-change plug-ins 11 on the frame 1, which are respectively connected to the electrical connectors of the entire vehicle, and connecting or disconnecting the plurality of first quick-change plug-ins 11 to the electrical connectors on the plurality of battery packs 2, the battery packs 2 in the integrated battery pack are connected in parallel, so that each battery pack 2 can supply power to the electrical components of the entire vehicle individually, ensuring that the battery packs 2 do not affect each other, and thus the battery pack 2 that needs to be replaced can be replaced without affecting the power supply of other normal battery packs 2.

[0048] Optionally, combined Figure 1 and Figure 2 As shown, the frame 1 is further provided with a second quick-change plug-in 12 , and a plurality of first quick-change plug-ins 11 are respectively connected to the second quick-change plug-in 12 , and the second quick-change plug-in 12 is used to connect to the electrical connector of the entire vehicle.

[0049] In this optional embodiment, multiple first quick-change plug-ins 11 are connected to the electrical connector of the entire vehicle through the second quick-change plug-in 12. When the entire integrated battery pack needs to be replaced, the frame 1 is separated from the vehicle body 100 by unlocking the second locking mechanism 4. At this time, the second quick-change plug-in 12 on the frame 1 is also separated from the electrical connector of the entire vehicle. After the replacement is completed, the integrated battery pack is locked to the vehicle body 100 by locking the second locking mechanism 4. At this time, the second quick-change plug-in 12 on the frame 1 forms a plug-in fit with the electrical connector of the entire vehicle, thereby connecting the high-voltage circuits of each battery pack 2 in the integrated battery pack, so that each battery pack 2 can supply power to the electrical components of the entire vehicle. In this way, by arranging the second quick-change plug-in 12 on the frame 1 and connecting or separating the multiple first quick-change plug-ins 11 with the electrical connector of the entire vehicle through the second quick-change plug-in 12, it is ensured that the integrated battery pack can be replaced and powered as a whole.

[0050] Furthermore, the second quick-change plug-in 12 is used to communicate with the vehicle terminal. In this way, the vehicle terminal can be used to monitor the operating parameters of each battery pack 2 in the integrated battery pack, such as temperature and power level, so that when an abnormality occurs in the operation of the battery pack 2, timely operations such as alarm or power off can be taken, thereby improving the safety of the integrated battery pack.

[0051] An embodiment of the present invention provides a vehicle including the integrated battery pack as described above.

[0052] Specifically, the integrated battery pack is usually installed on the vehicle body 100 and is located below the vehicle body 100. The multiple battery packs 2 of the integrated battery pack are respectively connected to the frame 1 through the first locking mechanism 3. When it is necessary to replace the battery of a single battery pack, the first locking mechanism 3 can be unlocked to separate the battery pack 2 from the frame 1. When the battery replacement is completed, the battery pack 2 can be fixed to the frame 1 by locking the first locking mechanism 3. The integrated battery pack can be lifted for battery replacement or mobile battery replacement. When lifting for battery replacement, the vehicle can be lifted at the battery replacement station to remove the single battery pack 2 from under the chassis for quick battery replacement; when mobile battery replacement is used, the battery replacement robot 400 can be used to remove the single battery pack 2 from under the vehicle body for quick battery replacement.

[0053] The beneficial effects of the vehicle of this embodiment relative to the prior art are the same as those of the above-mentioned integrated battery pack and will not be repeated here.

[0054] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
