[0022] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0023] The following is for reference. Figure 1 and Figure 2Describes a vehicle according to an embodiment of the present utility model.

[0024] like Figure 1 and Figure 2 As shown, the vehicle according to an embodiment of the present invention includes: a subframe assembly 1 and a battery 10. The subframe assembly 1 further includes: a subframe and a connecting bracket 20. The subframe is the main part of the subframe assembly 1, and mainly can block vibration and noise, reducing their direct entry into the vehicle compartment. The battery 10 mainly provides electrical energy to the vehicle and stores electrical energy. The connecting bracket 20 mainly serves a connecting function, connecting the battery 10 and the subframe, thereby making the subframe and the battery 10 form a whole.

[0025] like Figure 1 and Figure 2 As shown, the battery 10 is located at the rear end of the subframe, and the connecting bracket 20 is located between the subframe and the battery 10. The battery 10 is connected to the subframe via the connecting bracket 20. The battery 10 is located at the rear end of the subframe, and the connecting bracket 20 is located between the subframe and the battery 10. The battery 10 is connected to the subframe via the connecting bracket 20. One end of the connecting bracket 20 is connected to the battery 10, and the other end is connected to the subframe. This allows the subframe and battery 10 to form a single unit. Furthermore, with a slight increase in weight, the transmission path of rear lateral stiffness can be increased, significantly increasing the lateral stiffness of the rear of the vehicle. This effectively improves the vehicle's handling performance, enhancing its stability and driving safety.

[0026] Therefore, the connecting bracket 20 is positioned between the subframe and the battery 10. The battery 10 is connected to the subframe via the connecting bracket 20. This increases the transmission path of rear lateral stiffness with minimal weight increase. When the subframe is subjected to lateral force, the force can be transmitted to the battery 10 through the connecting bracket 20. At this time, the battery 10 can contribute a large portion of the stiffness, thereby greatly increasing the lateral stiffness of the rear of the vehicle. This can effectively improve the vehicle's motion performance and enhance its handling stability and driving safety.

[0027] Specifically, such as Figure 1 and Figure 2As shown, the battery 10 is provided with a mounting base 100, and the connecting bracket 20 is provided with a mounting hole 200. The mounting base 100 and the mounting hole 200 are positioned opposite each other, and the fastener 201 is fixed to the subframe through the mounting base 100 and the mounting hole 200. The mounting base 100 on the battery 10 primarily serves a mounting function, and the mounting hole 200 on the connecting bracket 20 also primarily serves a mounting function. The fastener 201 is fixed to the subframe through the mounting base 100 and the mounting hole 200. In other words, the connecting bracket 20 is fixed to the subframe by connecting the mounting base 100 and the mounting hole 200 using the fastener 201. The fastener 201 can be a bolt, which facilitates installation and disassembly, enhances practicality, and ensures structural reliability.

[0028] Among them, such as Figure 1 and Figure 2 As shown, the front and rear ends of the connecting bracket 20 are respectively provided with two mounting holes 200, and the front end of the battery 10 is provided with two mounting seats 100. The two mounting holes 200 at the front end of the connecting bracket 20 are connected to the subframe, and the two mounting seats 100 are provided in a one-to-one correspondence with the two mounting holes 200 at the rear end of the connecting bracket 20. The connecting bracket 20 has four mounting holes 200, two at the front and two at the rear. The front of the battery 10 has two mounting seats 100 for mounting. The two mounting holes 200 at the front of the connecting bracket 20 connect to the subframe, and the two mounting seats 100 correspond one-to-one with the two mounting holes 200 at the rear of the connecting bracket 20. This allows the connecting bracket 20 to be positioned between the subframe and the battery 10, connecting the battery 10 to the subframe. This makes the subframe and battery 10 a single unit. Furthermore, with only a slight increase in weight, it increases the transmission path of rear lateral stiffness, significantly increasing the lateral stiffness of the rear of the vehicle, thereby effectively improving the vehicle's handling performance, stability, and driving safety. The number of fasteners 201 can be four.

[0029] In addition, such as Figure 1 and Figure 2 As shown, the connecting bracket 20 is constructed in a butterfly shape from front to back. The butterfly shape of the connecting bracket 20 results in a reasonable and reliable structure. It significantly increases the lateral stiffness of the rear of the vehicle while controlling cost and weight. Secondly, it reduces the overall weight of the subframe assembly 1 while ensuring the load-bearing channels, achieving structural lightweighting, reducing cost and energy consumption. Furthermore, it improves vehicle vibration convergence, initial roll control, and rear axle following performance.

[0030] Of course, such as Figure 1 and Figure 2As shown, the connecting bracket 20 is provided with a first weight-reducing hole 202 and a second weight-reducing hole 203. There are two first weight-reducing holes 202, which are respectively located at both ends of the second weight-reducing hole 203. The first weight-reducing holes 202 and the second weight-reducing holes 203 are mainly used for weight reduction. There are two first weight-reducing holes 202 and one second weight-reducing hole 203, which are respectively located at both ends of the second weight-reducing hole 203. This can reduce the overall weight of the connecting bracket 20. In addition, the first weight-reducing holes 202 and the second weight-reducing holes 203 can also prevent stress concentration in the connecting bracket 20 and avoid structural damage to the connecting bracket 20 due to installation and stress.

[0031] Optionally, such as Figure 1 and Figure 2 As shown, both the first weight-reducing hole 202 and the second weight-reducing hole 203 are constructed as elongated holes. Elongated holes can significantly reduce the overall weight of the component. Constructing both the first weight-reducing hole 202 and the second weight-reducing hole 203 as elongated holes significantly reduces the overall weight of the connecting bracket 20, facilitating lightweight design. Furthermore, elongated holes can disperse stress and prevent stress concentration, thereby improving the component's resistance to fracture. Constructing both the first weight-reducing hole 202 and the second weight-reducing hole 203 as elongated holes prevents stress concentration in the connecting bracket 20, avoiding structural damage due to installation and stress. In other words, constructing both the first weight-reducing hole 202 and the second weight-reducing hole 203 as elongated holes results in better weight reduction and prevention of stress concentration, thus reducing manufacturing costs and overall weight.

[0032] Furthermore, such as Figure 2 As shown, the connecting bracket 20 has a first flange 204 at its front and rear ends, and a second flange 205 around the second weight-reducing hole 203. Both the first flange 204 and the second flange 205 enhance the structural strength of the connecting bracket 20, enabling it to better withstand external pressure and load. Furthermore, they can prevent incorrect installation or use to a certain extent, improving the safety and reliability of the connecting bracket 20. With the first flange 204 at its front and rear ends and the second flange 205 around the second weight-reducing hole 203, the connecting bracket 20 has higher structural strength, better meeting actual working conditions. This significantly increases the lateral stiffness of the rear of the vehicle, effectively improving the vehicle's motion performance and enhancing its handling stability and driving safety.

[0033] In addition, such as Figure 1 and Figure 2 As shown, the thickness of the connecting bracket 20 is 'a', and the value of 'a' ranges from 2mm to 3mm. It should be noted that the thickness 'a' of the connecting bracket 20 needs to meet certain requirements. Specifically, the thickness 'a' of the connecting bracket 20 cannot be too small, i.e., less than 2mm. If the thickness 'a' is too small, it will affect the connection effect of the connecting bracket 20 to the battery 10 and the subframe, and may also affect the lateral stiffness of the rear axle of the vehicle, thus affecting the vehicle's handling performance. At the same time, the thickness 'a' of the connecting bracket 20 cannot be too large, i.e., greater than 3mm. If the connecting bracket 20 is too thick, it will increase costs and affect the overall weight and energy consumption of the subframe assembly 1, even if it can connect the battery 10 and the subframe.

[0034] It should be noted that, as Figure 1 and Figure 2 As shown, the connecting bracket 20 is a rigid structural component. Rigid structural components have strong rigidity and stability. By making the connecting bracket 20 a rigid structural component, the connecting bracket 20 has strong rigidity and stability, which can prevent the connecting bracket 20 from undergoing lateral deformation and instability, and can avoid the connecting bracket 20 from undergoing large deformation.

[0035] In addition, such as Figure 1 and Figure 2 As shown, the connecting bracket 20 is a one-piece molded structural component. This makes the structure of the connecting bracket 20 more stable and robust, with higher structural strength and rigidity, facilitating its installation. Furthermore, processing the connecting bracket 20 requires only one processing mold, which improves production efficiency, reduces costs, decreases energy consumption, and facilitates the manufacturing of the connecting bracket 20.
