Abstract
Description
Technical Field
[0001] This application belongs to the field of electric vehicle technology, and in particular relates to a battery swapping bracket for electric vehicles and an electric vehicle. Background Technology
[0002] Electric vehicles have experienced rapid development in recent years. Faced with this rapidly growing market, improving charging speed has become a major challenge for further development. Currently, the main measures to improve charging speed are equipping electric vehicles with fast charging or battery swapping systems.
[0003] Among them, battery swapping has won the favor of users due to its extremely fast charging speed and better charging experience. However, because battery swapping vehicles add a dedicated battery swapping system, the vehicle body, battery pack and other related components need to be customized. This results in higher costs and longer development cycles for battery swapping vehicles, which restricts their popularization and further development.
[0004] Currently, existing battery swapping vehicles typically achieve battery swapping by adding battery swapping mechanisms (such as battery swapping connectors, battery swapping bolts, and battery swapping brackets). However, the battery swapping brackets currently on the market mainly adopt a complex one-piece structure design. These one-piece battery swapping brackets usually have the problems of being heavy and having high production costs, and they are also difficult to adapt to different models of battery swapping vehicles. Utility Model Content
[0005] This application provides a battery swapping bracket and an electric vehicle for electric vehicles, in order to solve the technical problems of long development cycles and high costs associated with battery swapping vehicles.
[0006] According to one aspect of this application, a battery swapping bracket for an electric vehicle is provided. The bracket includes: a bracket body for connecting to the vehicle body; and a battery swapping nut for connecting to the battery pack of the electric vehicle. The bracket body includes: a main body portion; a first extension portion extending along the length of the main body portion and connected to a first end of the main body portion; and a second extension portion extending along the length of the main body portion and connected to a second end of the main body portion opposite to the first end. The battery swapping nut is connected to the main body portion, and there is a height difference between the first extension portion and the main body portion in the height direction.
[0007] Optionally, the main body has a first mounting surface in the height direction, and the battery swapping nut is disposed on the first mounting surface and detachably connected to the main body.
[0008] Optionally, the distance between the second extension and the first mounting surface in the height direction is smaller than the distance between the first extension and the first mounting surface in the height direction.
[0009] Optionally, the battery swapping nut is provided with a first through hole and at least two second through holes, the second through holes being located on different sides of the first through hole in the length direction; the battery swapping nut is detachably connected to the main body through the second through holes and connected to the battery swapping bolt on the battery pack through the first through holes.
[0010] Optionally, the battery replacement nut is provided with two second through holes, and the center of the first through hole is on the same straight line as the centers of the two second through holes located on different sides of the center.
[0011] Optionally, the cross-section of the support body in the HL plane is a Z-shaped structure.
[0012] Optionally, the first extension is provided with a first mounting hole, and the first extension is connected to a protruding structure on the longitudinal beam of the vehicle body through the first mounting hole; the second extension is provided with a second mounting hole, and the second extension is connected to the longitudinal beam of the vehicle body through the second mounting hole.
[0013] Optionally, the center of the first via is on the same straight line as the center of the first mounting hole and the center of the second mounting hole.
[0014] Optionally, the second extension is also provided with positioning holes for positioning the mounting bracket body.
[0015] Optionally, the second via is a threaded hole or a through hole.
[0016] Optionally, the battery swapping nut is integrally formed with the bracket body, and there is no height difference between the second extension and the main body in the height direction. The cross-section of the bracket body in the HL plane is a Z-shaped structure.
[0017] According to another aspect of this application, an electric vehicle is provided, which includes a body, a battery pack, and the battery swapping bracket described above.
[0018] In summary, the battery swapping bracket and electric vehicle provided in this application have at least the following beneficial effects: In one embodiment of this application, the battery swapping bracket is a split structure consisting of a bracket body and a battery swapping nut detachably connected to the bracket body. Compared with an integral battery swapping bracket, this split battery swapping bracket is lighter, simpler in structure, and lower in cost, which is more advantageous for the commercialization of battery swapping vehicles. Furthermore, this application sets the distance between the second extension of the bracket body and the first mounting surface to be greater than the distance between the first extension and the first mounting surface. This allows for connection to different parts of the vehicle body via first and second extensions of different heights, minimizing modifications to the existing electric vehicle body and ensuring that battery swapping and non-battery swapping models can share a single body. This is extremely convenient for projects that did not consider battery swapping models in the early stages of development, reducing the development cycle for battery swapping models. In another embodiment of this application, an integral battery swapping bracket is used. This integral battery swapping bracket not only eliminates the assembly gaps of the split structure, improving the overall structural strength and vibration resistance reliability, but also reduces the number of parts and assembly steps, lowering manufacturing costs and improving production efficiency.

[0024] Figure 1 This is a structural schematic diagram of the electric vehicle 1000 provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of the battery swapping bracket 100 for an electric vehicle 1000 provided in an embodiment of this application. Figure 3 This is a side view of the support body 10 of the battery swapping bracket 100 provided in this embodiment of the application. Figure 4 This is a schematic diagram of the structure of a battery swapping bracket 100' provided in another embodiment of this application.
[0025] Reference Figures 1 to 3 The electric vehicle 1000 provided in this application embodiment includes a vehicle body 300, a battery pack 200, and a battery swapping bracket 100. The battery pack 200 can be detachably connected to the battery swapping bracket 100, and the battery swapping bracket 100 can be detachably connected to the vehicle body 300, thereby enabling the installation and replacement of the battery pack 200.
[0026] It should be noted that the electric vehicle 1000 in this application can be either a battery-swapping model or a non-battery-swapping model. In a battery-swapping model, the battery pack is replenished by replacing the battery pack when its charge is low, while non-battery-swapping models are generally equipped with fast charging, which replenishes the battery pack when its charge is low.
[0027] The battery swapping bracket 100 of this application can be applied to electric vehicles, both battery swapping and non-battery swapping models. Specifically, the battery swapping bracket 100 includes a bracket body 10 and a battery swapping nut 20 connected to the bracket body 10. The bracket body 10 is used to connect to the vehicle body 300 of the electric vehicle 1000, and the battery swapping nut 20 is used to connect to the battery pack 200 of the electric vehicle 1000. More specifically, the battery pack 200 is provided with battery swapping bolts, and the battery pack 200 is connected to the battery swapping nut 20 on the bracket body 10 through the battery swapping bolts thereon.
[0028] As shown in the figure, the support body 10 includes a main body 11, a first extension 12, and a second extension 13. The first extension 12 extends along the length direction L of the main body 11 and is connected to a first end of the main body 11. The second extension 13 extends along the length direction L and is connected to a second end of the main body 11 opposite to the first end. The battery replacement nut 20 is connected to the main body 11, and there is a height difference between the first extension 12 and the main body 11 in the height direction H. It should be noted that the phrase "the battery replacement nut 20 is connected to the main body 11" here includes both a detachable connection and a non-detachable connection between the battery replacement nut and the main body.
[0029] Specifically, in Figures 1 to 3 In the illustrated embodiment, the main body 11 has a first mounting surface A1 in its height direction H, and the battery swapping nut 20 is disposed on the first mounting surface A1 and detachably connected to the main body 11. It should be noted that the height direction H is approximately parallel to the direction of gravity. The first extension 12 extends in the length direction L of the main body 11 and is connected to a first end of the main body 11. The second extension 13 extends in the length direction L and is connected to a second end of the main body 11 opposite to the first end; that is, the first extension 12 and the second extension 13 are located at opposite ends in the length direction L of the main body 11. In this embodiment, since the battery swapping bracket 100 is a split structure consisting of a bracket body 10 and a battery swapping nut 20 detachably connected to the bracket body 10, compared to an integral battery swapping bracket, the split battery swapping bracket 100 is lighter, simpler in structure, and lower in cost, which is more advantageous for the commercialization of battery swapping vehicles.
[0030] Optionally, the distance in the height direction H between the second extension 13 and the first mounting surface A1 is less than the distance in the height direction H between the first extension 12 and the first mounting surface A1. It should be noted that the distance in the height direction H between the first extension 12 and the first mounting surface A1 refers to the distance between the second mounting surface A2 and the first mounting surface A1, which will be described in detail later, and the distance in the height direction H between the second extension 13 and the first mounting surface A1 refers to the distance between the third mounting surface A3 and the first mounting surface A1, which will be described in detail later.
[0031] Specifically, when the battery swapping bracket 100 is installed on the vehicle body 300, the first extension 12 and the second extension 13 of the bracket body 10 can be connected to the corresponding parts of the vehicle body 300 respectively. Since the distance between the second extension 13 and the first mounting surface A1 in the height direction H is smaller than the distance between the first extension 12 and the first mounting surface A1 in the height direction H, the first extension 12 can be connected to the protruding structure on the longitudinal beam of the vehicle body 300, and the second extension 13 can be connected to the part of the longitudinal beam of the vehicle body 300 that does not have a protruding structure.
[0032] This application sets the distance in the height direction H between the second extension 13 of the bracket body 10 and the first mounting surface A1 to be smaller than the distance in the height direction H between the first extension 12 and the first mounting surface A1. The first extension 12 and the second extension 13 of different heights can be connected to different parts of the vehicle body 300 respectively. This can minimize the modification to the body of the existing electric vehicle and ensure that the battery swapping model and the non-battery swapping model can share a body. This is extremely convenient for projects that have not considered the layout of battery swapping models in the early stage of development and can reduce the development cycle of battery swapping models.
[0033] Furthermore, in this application, based on the detachable connection between the bracket body 10, the battery swapping nut 20, and the vehicle body 300, the following two methods can be used for quick battery swapping: First, it is not necessary to remove the battery swapping bracket 100 from the vehicle body 300. Instead, the battery swapping bolt of the old battery pack 200 is directly disconnected from the battery swapping nut 20 on the battery swapping bracket 100 to remove the battery pack 200 from the battery swapping bracket 100. Then, the new battery pack 200 is connected to the battery swapping bracket via its battery swapping bolt. Alternatively, the battery pack 20 can be connected using the battery swapping nut 20 of the 100, thus completing the battery swapping and energy replenishment; or, instead of removing the old battery pack 200 from the battery swapping bracket 100, the battery swapping bracket 100 can be directly removed from the vehicle body 300, and the battery swapping bracket 100 and the battery pack 200 connected to it can be removed together from the vehicle body 300, and then the new battery pack 200 and the new battery swapping bracket 100 connected to it can be connected to the vehicle body 300 through the bracket body 10 of the battery swapping bracket 100, thus completing the battery swapping and energy replenishment.
[0034] In the second method, the battery swapping bracket 100 and the battery pack 200 connected to it are regarded as a whole (hereinafter referred to as the battery swapping assembly) and are installed on or removed from the vehicle body 300 as a whole. Thus, during the battery swapping and energy replenishment process, it is only necessary to remove the old battery swapping assembly from the vehicle body 300 (i.e., disconnect the bracket body 10 from the vehicle body 300) and then install the new battery swapping assembly on the vehicle body 300 (i.e., connect the bracket body 10 to the vehicle body 300). The whole process only requires loosening or tightening a few bolts, thereby greatly improving the installation and replacement efficiency of the battery pack 200 on the vehicle body 300.
[0035] In some embodiments, refer to Figure 2 The battery swapping nut 20 is provided with a first through hole B1 and at least two second through holes B2. The second through holes B2 are located on different sides of the first through hole B1 in the length direction L. The battery swapping nut 20 is detachably connected to the main body 11 through the second through holes B2 and connected to the battery swapping bolt on the battery pack 200 through the first through holes B1.
[0036] Specifically, along the length L of the main body 11, the first through hole B1 is located in the middle of the main body 11 and can be a threaded hole. The battery swapping nut 20 is threadedly connected to the battery swapping bolt on the battery pack 200 through the first through hole B1. The second through hole B2 is located at both ends of the main body 11 and can be a threaded hole or a through hole. The battery swapping nut 20 is detachably connected to the main body 11 through the second through hole B2. Thus, in this embodiment, along the length L of the main body 11, the battery pack 200 is connected to the battery swapping bolt on the battery pack 200 through the first through hole B1 located in the middle of the main body 11, and to the main body 11 through the second through holes B2 located at both ends of the main body 11, thereby realizing the connection between the battery pack 200 and the battery swapping bracket 100. This connection method is simple and efficient, which helps to improve the installation and replacement efficiency of the battery pack 200. Furthermore, since there are second through holes B2 on both sides of the first through hole B1, the connection strength between the battery swapping nut 20 and the bracket body 10 can be guaranteed, thereby improving the stability of the battery pack 200 during use.
[0037] It should be noted that, in order to further improve the connection strength between the bracket body 10 and the vehicle body 300, other through hole structures can be added around the second through hole B2, but this application does not make specific limitations.
[0038] In some embodiments, refer to Figure 2 The battery replacement nut 20 is provided with two second through holes B2. The center of the first through hole B1 is on the same straight line as the centers of the two second through holes B2 located on different sides of the first through hole B1.
[0039] In this embodiment, the center of the first through hole B1 and the centers of the second through holes B2 on both sides are set on the same straight line. On the one hand, this simplifies the assembly process between the battery swapping nut 20 and the bracket body 10, reduces the difficulty of hole alignment during installation, and helps to shorten the battery swapping time and reduce connection errors. On the other hand, the symmetrical design of the second through hole B2 can make the force distribution more uniform, improve the connection stability between the battery swapping nut 20 and the bracket body 10, thereby further improving the stability of the battery pack 200 during use.
[0040] In some embodiments, refer to Figure 2 The first extension 12 is provided with a first mounting hole C1 and has a second mounting surface A2 facing the longitudinal beam of the vehicle body 300. The first extension 12 is connected to the protruding structure on the longitudinal beam of the vehicle body 300 through the first mounting hole C1. The second extension 13 is provided with a second mounting hole C2 and has a third mounting surface A3 facing the longitudinal beam of the vehicle body 300. The second extension 13 is connected to the longitudinal beam of the vehicle body 300 through the second mounting hole C2.
[0041] Understandably, the non-protruding structural part of the longitudinal beam of the vehicle body 300 is provided with a mounting hole corresponding to the second mounting hole C2, and the protruding structure of the longitudinal beam of the vehicle body 300 is provided with a mounting hole corresponding to the first mounting hole C1, so as to realize the installation between the battery swapping bracket 100 and the vehicle body 300.
[0042] In this embodiment, since the battery swapping bracket 100 is connected to the vehicle body 300 through the first mounting hole C1 provided on the first extension 12 and the second mounting hole C2 provided on the second extension 13, the battery swapping function can be realized by simply adding a few mounting holes (such as threaded holes) to the vehicle body 300 of the existing battery swapping vehicle, thereby greatly shortening the development cycle of the battery swapping vehicle.
[0043] In some embodiments, refer to Figure 2 The center of the first through hole B1, the center of the first mounting hole C1, and the center of the second mounting hole C2 are on the same straight line. This symmetrical design of the first mounting hole C1 and the second mounting hole C2 makes the force distribution more even, improves the connection stability between the battery swapping bracket 100 and the vehicle body 300, and thus further improves the stability of the battery pack 200 during use.
[0044] It should be understood that the center of the first through hole B1, the center of the first mounting hole C1, and the center of the second mounting hole C2 may not be aligned on the same straight line, depending on actual needs. This arrangement ensures the structural strength of the battery swapping bracket 100 while enhancing its flexibility and adaptability, reducing installation tolerances, and thus improving the overall structural reliability.
[0045] In some embodiments, refer to Figure 2 The second extension 13 is also provided with a positioning hole D. Specifically, the positioning hole D can be provided on one side of the second mounting hole C2 in the width direction W of the main body 11. During the installation process between the battery swapping bracket 100 and the vehicle body 300, the positioning hole D can be used to position the bracket body 10 of the battery swapping bracket 100, thereby quickly aligning the first mounting hole C1 and the second mounting hole C2 with the corresponding mounting holes on the vehicle body 300, thereby improving the battery swapping efficiency of the battery pack 200.
[0046] In some embodiments, refer to Figure 3 The main body 11 of the support body 10 has a roughly Z-shaped cross-section in the HL plane. It should be noted that because the distances in the height direction H between the first extension 12 and the second extension 13 and the first mounting surface A1 of the main body 11 are different, the main body 11 is actually an irregular Z-shaped structure; that is, the two sides of the Z-shaped main body 11 are asymmetrical. Here, setting the main body 11 to a Z-shaped structure can improve the overall structural strength of the support body 10.
[0047] Figure 4 This is a schematic diagram of the structure of a battery swapping bracket 100' provided in another embodiment of this application. Figure 2 and Figure 3 Unlike the split-type battery swapping bracket 100 shown, the battery swapping bracket 100' in this embodiment adopts a simplified integrated structure design, that is, the bracket body 10 and the battery swapping nut 20 are integrally formed into a single structure through an integrated molding process. Specifically, the battery swapping bracket 100' includes a bracket body 10' and a battery swapping nut 20', wherein the bracket body 10' is used to connect to the body 300 of the electric vehicle 1000, and the battery swapping nut 20' is used to connect to the battery pack 200 of the electric vehicle 1000 and is integrally formed with the main body 11'. The bracket body 10' includes a main body 11', a first extension 12' and a second extension 13', wherein the first extension 12' extends in the length direction L of the main body 11' and is connected to a first end of the main body 11'; the second extension 13' extends in the length direction L and is connected to a second end of the main body 11' opposite to the first end. In this design, there is no height difference between the second extension 13' and the main body 11' in the height direction H, while there is a height difference between the first extension 12' and the main body 11' in the height direction H. Furthermore, the cross-section of the support body 10' in the HL plane is a Z-shaped structure. This simplified integrated structure not only eliminates the assembly gaps of the split structure, improving the overall structural strength and vibration resistance reliability, but also reduces the number of parts and assembly steps, lowering manufacturing costs and increasing production efficiency.
[0048] In a second aspect, an electric vehicle is provided. The electric vehicle includes a body 300, a battery pack 200, and the aforementioned battery swapping bracket.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
