For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] Furthermore, it should be noted that in the description of this application, the terms "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0038] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0039] As shown in the background art, in the prior art, the battery frame bracket includes a bracket body and two sub-frames disposed at the bottom of the bracket body. The battery frame is placed on the bracket body, and the sub-frames are located between the bracket body and the vehicle frame. The bracket body is connected to the vehicle frame through the sub-frames.

[0040] However, the aforementioned battery frame is prone to tipping over.

[0041] Based on this, the chassis structure and vehicle provided in this application include a chassis frame, a battery frame bracket, and at least one connecting component. The battery frame bracket includes a bracket body mounted on the chassis frame, which supports the battery frame to ensure its stability during vehicle operation. The bracket body contacts the chassis frame, reducing the gap between them and lowering the height of the battery frame bracket. The bracket body has multiple mounting portions, and the connecting component includes a first connector and a second connector. The first connector is connected to the bracket body via at least one mounting portion; the second connector connects the first connector to the chassis frame, thus stably fixing the battery frame bracket to the chassis frame. The chassis structure and vehicle provided in this application reduce the height of the battery frame bracket, thereby reducing the tipping moment of the battery frame and lowering the likelihood of it tipping over.

[0042] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] Reference Figures 1 to 6 As shown, the chassis structure provided in this application includes: a frame 100, a battery frame bracket 200 and at least one connecting component 300. The battery frame bracket 200 includes a bracket body 210, which is disposed on the frame 100 and has a plurality of mounting portions 211.

[0044] The connecting assembly 300 includes a first connector 310 and a second connector 320. The first connector 310 is connected to the bracket body 210 via at least one mounting part 211. The second connector 320 connects the first connector 310 to the frame 100.

[0045] It should be noted that the frame 100 is the basic structure of the entire vehicle. The frame 100 provides a framework to support and connect other components. Therefore, the frame 100 needs to have sufficient strength and rigidity to withstand the weight of the vehicle and various forces generated during driving.

[0046] It should also be noted that the bracket body 210 is mounted on the vehicle frame 100 and is used to support the battery frame to keep it stable during vehicle operation. The bracket body 210 contacts the vehicle frame 100, and the vehicle frame 100 provides support for the bracket body 210, reducing the gap between the bracket body 210 and the vehicle frame 100 and lowering the height of the battery frame bracket 200, thereby reducing the tipping moment of the battery frame and lowering the possibility of the battery frame tipping over.

[0047] The bracket body 210 has multiple mounting portions 211. A first connector 310 is connected to the bracket body 210 via the mounting portions 211, and a second connector 320 connects the first connector 310 to the vehicle frame 100. The first connector 310 and the second connector 320 together connect the bracket body 210 to the vehicle frame 100, so that the battery frame bracket 200 is stably fixed to the vehicle frame 100. This compact connection ensures direct contact between the bracket body 210 and the vehicle frame 100, thereby reducing the height of the battery frame bracket 200.

[0048] In specific implementation, the mounting part 211 can be a threaded hole, and bolts or screws can be used to fix the bracket body 210 and the first connector 310. The mounting part 211 can also be a slot or a buckle to snap the first connector 310 and the bracket body 210 together. As long as the connection between the first connector 310 and the bracket body 210 can be achieved, this application embodiment does not impose too many restrictions on this.

[0049] For example, the first connector 310 and the second connector 320 may be connected by bolts or screws, by welding, or by other means.

[0050] For example, the second connector 320 can be connected to the frame 100 by bolts or screws, by welding, or by other means.

[0051] Understandably, compared to the battery frames in existing technologies that are prone to tipping over, the chassis structure and vehicle provided in this application embodiment, through the arrangement of a frame 100, a battery frame bracket 200, and at least one connecting component 300, provide a chassis structure. The battery frame bracket 200 includes a bracket body 210, which is mounted on the frame 100 and supports the battery frame to ensure its stability during vehicle operation. The bracket body 210 contacts the frame 100, reducing the gap between the bracket body 210 and the frame 100 and lowering the height of the battery frame bracket 200. The bracket body 210 has multiple mounting portions 211. The connecting component 300 includes a first connector 310 and a second connector 320. The first connector 310 is connected to the bracket body 210 through at least one mounting portion 211; the second connector 320 connects the first connector 310 to the frame 100, thereby stably fixing the battery frame bracket 200 to the frame 100. The chassis structure and vehicle provided in this application reduce the height of the battery frame bracket 200, thereby reducing the overturning moment of the battery frame and reducing the possibility of the battery frame overturning.

[0052] In some embodiments, refer to Figure 5 As shown, the first connector 310 includes a first connecting portion 311 and a second connecting portion 312 disposed on one side of the first connecting portion 311. The first connecting portion 311 is connected to the mounting portion 211, and the second connecting portion 312 is connected to the second connector 320.

[0053] Specifically, the first connecting part 311 is connected to the mounting part 211 so that the first connecting member 310 can be fixed to the bracket body 210. The second connecting part 312 is connected to the second connecting member 320 so that the second connecting member 320 connects the first connecting member 310 to the frame 100. This ensures the stability between the bracket body 210 and the frame 100 and reduces the possible shaking and loosening of the bracket body 210 during vehicle operation.

[0054] It should be noted that the first connecting part 311 and the second connecting part 312 can be integrally formed; the first connecting part 311 and the second connecting part 312 can also be manufactured separately and then fixed by welding or bonding. This application embodiment does not impose too many restrictions on this.

[0055] In some embodiments, refer to Figure 5 As shown, the first connecting part 311 and the second connecting part 312 are perpendicular to each other. The first connecting part 311 abuts against the outer side wall of the bracket body 210, and the second connecting part 312 abuts against part of the second connecting member 320.

[0056] Understandably, the first connecting part 311 and the second connecting part 312 are perpendicular to each other, which enables the first connecting member 310 to better resist torsional force and lateral force, reducing the possibility of the first connecting member 310 shaking or deforming during vehicle operation.

[0057] It should be noted that the vertical design makes alignment and fixation easier during installation, simplifies the assembly process, and improves the installation efficiency of the bracket body 210.

[0058] It should also be noted that the first connecting part 311 abuts against the outer side wall of the bracket body 210, and the second connecting part 312 abuts against the second connecting member 320, which can provide multi-directional support, thereby dispersing and transmitting forces from different directions and enhancing the stability of the bracket body 210.

[0059] In some embodiments, refer to Figure 3 and Figure 5 As shown, the mounting part 211 is a mounting hole, the first connecting part 311 has a through hole, and the connecting assembly 300 also includes a plurality of fasteners 330, which are connected to the bracket body 210 in sequence through the through hole and the mounting hole.

[0060] Understandably, by using fasteners 330, a robust mechanical connection can be achieved, thereby withstanding greater loads and vibrations and further improving the stability of the bracket body 210 during use. Exemplarily, fasteners 330 can be bolts and nuts, or other components; this application embodiment does not impose excessive limitations on this.

[0061] In practice, anti-loosening washers or thread-locking agents can be used in combination to further improve the reliability of the connection and prevent loosening in a vibrating environment.

[0062] In some embodiments, refer to Figure 5 As shown, the second connector 320 includes a third connector 321 and a fourth connector 322 disposed on one side of the third connector 321. The third connector 321 is connected to the second connector 312, and the fourth connector 322 is connected to the frame 100.

[0063] Specifically, by providing the third connecting part 321 and the fourth connecting part 322, a connection position is provided for the second connecting part 312 and the frame 100, which together achieves the stability between the bracket body 210 and the frame 100.

[0064] It should be noted that the third connecting part 321 and the fourth connecting part 322 can be integrally formed; the third connecting part 321 and the fourth connecting part 322 can also be manufactured separately and then fixed by welding or bonding. This application embodiment does not impose too many restrictions on this.

[0065] In some embodiments, refer to Figure 5 and Figure 6 As shown, the third connecting part 321 and the fourth connecting part 322 are perpendicular to each other. The third connecting part 321 abuts against the bottom of the second connecting part 312 and the bracket body 210, respectively, and the fourth connecting part 322 abuts against the frame 100.

[0066] Understandably, the third connecting part 321 and the fourth connecting part 322 are perpendicular to each other, which allows the second connecting part 320 to better resist torsional and lateral forces, reducing the possibility of the second connecting part 320 shaking or deforming during vehicle operation. It should be noted that the vertical design makes alignment and fixing easier during installation, simplifies the assembly process, and further improves installation efficiency.

[0067] It should also be noted that the third connecting part 321 abuts against the bottom of the second connecting part 312 and the bracket body 210 respectively, and the fourth connecting part 322 abuts against the frame 100, which can provide multi-directional support, thereby dispersing and transmitting forces from different directions, and further enhancing the stability of the bracket body 210.

[0068] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 As shown, the bracket body 210 facing the frame 100 includes a first inclined surface 212, a support surface 213, and a second inclined surface 214 arranged in sequence. The first inclined surface 212 and the second inclined surface 214 are both connected to the support surface 213 by an arc, and the support surface 213 abuts against the frame 100.

[0069] Understandably, the bracket body 210 is in direct contact with the frame 100 via the support surface 213, which provides a stable plane, allowing the bracket body 210 to be securely placed on the frame 100. The first inclined surface 212 and the second inclined surface 214 make it easier to align and install the bracket body 210 with the frame 100, improving installation efficiency.

[0070] It should be noted that both the first inclined surface 212 and the second inclined surface 214 are connected to the support surface 213 by a rounded transition, which reduces the presence of sharp edges and corners, thereby reducing the possibility of stress concentration and fatigue failure, which helps to improve the integrity and durability of the bracket body 210 and extend the service life of the bracket body 210.

[0071] In some embodiments, refer to Figure 1 and Figure 3 As shown, the bracket body 210 is perpendicular to the frame 100, and each mounting part 211 is spaced apart along the extension direction of the bracket body 210, and the projection of the mounting part 211 toward the frame 100 is located on the support surface 213.

[0072] Specifically, the bracket body 210 is perpendicular to the frame 100, which can improve the load-bearing capacity and stability of the bracket body 210, reduce the impact of lateral forces on the bracket body 210, and improve the anti-tipping ability, so that the bracket body 210 can effectively bear the weight of the battery box and transfer it to the frame 100.

[0073] It should be noted that the spaced mounting section 211 can provide multiple mounting positions, so that the bracket body 210 can be installed on the frame 100 at different positions, providing a certain degree of flexibility and adapting to frame 100s of different widths.

[0074] It should also be noted that the projection of the mounting part 211 is located on the support surface 213, so that the force of the mounting part 211 can be directly transmitted to the support surface 213, thereby effectively transferring the load to the frame 100, reducing local stress concentration and improving the durability of the bracket body 210.

[0075] In some embodiments, refer to Figure 3 As shown, the battery frame bracket 200 also includes a support assembly 220, which includes a first support member 221 and a second support member 222. The first support member 221 and the second support member 222 have an included angle, and both ends of the first support member 221 and the second support member 222 are connected to the bracket body 210.

[0076] Understandably, the first support member 221 and the second support member 222 can be used to jointly support the battery or battery frame by setting an included angle between the first support member 221 and the second support member 222 (i.e., Figure 3 As indicated by the middle arrow α), a triangular support structure can be formed, which helps to improve the rigidity and stability of the support component 220, enabling the support component 220 to more effectively distribute and bear the weight from the battery or battery box, as well as the dynamic load generated during vehicle operation. Exemplarily, the included angle can be 30 degrees, 45 degrees, or 60 degrees, or other angles; this application embodiment does not impose excessive limitations on this.

[0077] It should be noted that the first support member 221 may include two connecting rods, which are located on both sides of the second support member 222 respectively. One end of the connecting rod is connected to the second support member 222, and the other end of the connecting rod is connected to the bracket body 210.

[0078] This application also provides a vehicle, including a vehicle body and a chassis structure disposed on the vehicle body.

[0079] The specific structure and working method of the chassis structure have been described in detail in the above embodiments, and will not be repeated here.

[0080] Those skilled in the art will understand that the chassis structure and vehicle provided in this application include a chassis structure comprising a frame 100, a battery frame bracket 200, and at least one connecting assembly 300. The battery frame bracket 200 includes a bracket body 210, which is mounted on the frame 100 and supports the battery frame to ensure its stability during vehicle operation. The bracket body 210 contacts the frame 100, reducing the gap between the bracket body 210 and the frame 100 and lowering the height of the battery frame bracket 200. The bracket body 210 has multiple mounting portions 211. The connecting assembly 300 includes a first connector 310 and a second connector 320. The first connector 310 is connected to the bracket body 210 via at least one mounting portion 211; the second connector 320 connects the first connector 310 to the frame 100, thereby stably fixing the battery frame bracket 200 to the frame 100. The chassis structure and vehicle provided in this application reduce the height of the battery frame bracket 200, thereby reducing the overturning moment of the battery frame and reducing the possibility of the battery frame overturning.
