Detailed Implementation

[0024] In related technologies, the subframe assembly structure mainly adopts two forms: a straight-line structure and a U-shaped structure, which have the problem of poor impact resistance.

[0025] To address the aforementioned problems, this utility model provides a front subframe assembly 10 and a vehicle, which can absorb and disperse collision energy and improve impact resistance when a vehicle collision occurs.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] The following describes in detail, through embodiments and in conjunction with the accompanying drawings, a front subframe assembly 10 provided by this utility model, the overall structure of the vehicle, its working principle, and the technical effects achieved. Figure 1 This is a structural schematic diagram of the front subframe assembly 10 provided in this embodiment from a first-view perspective. Figure 2 This is a structural schematic diagram of the front subframe assembly 10 provided in this embodiment from a second-view perspective. Please refer to... Figure 1 and Figure 2 This utility model provides a front subframe assembly 10, including a front crossbeam 100, a left longitudinal beam 200, a rear crossbeam 300, a right longitudinal beam 400, and a connecting assembly 500.

[0033] The front crossbeam 100, left longitudinal beam 200, rear crossbeam 300, and right longitudinal beam 400 are interconnected in pairs to form a square frame. It is easy to understand that the square frame, as a closed structure, can absorb and disperse impact energy when subjected to external forces, improving the protection of internal components. Based on the above, to facilitate the application of the front subframe assembly 10 provided in this application to different types of vehicles and improve versatility, the connecting assembly 500 includes two connecting brackets 530 respectively located on the left longitudinal beam 200 and the right longitudinal beam 400.

[0034] When the front subframe assembly 10 is used in an electric vehicle, the connecting bracket 530 is used to connect the protective beam. It should be noted that the protective beam is a battery pack protective beam, with both ends connected to two connecting brackets 530 to absorb and disperse impact energy during a collision, reducing damage to the battery pack. When the front subframe assembly 10 is used in a gasoline vehicle, the connecting bracket 530 is used to connect the force transmission rods. It should be noted that there are two force transmission rods, each corresponding to a connecting bracket 530, which provides a certain degree of vibration isolation and helps absorb some impact energy.

[0035] Considering that steel has extremely high yield strength and tensile strength, enabling it to withstand significant external forces without permanent deformation or fracture, the front crossbeam 100, left longitudinal beam 200, rear crossbeam 300, and right longitudinal beam 400 are all made of steel to further enhance the load-bearing capacity and impact resistance of the front subframe assembly 10. Furthermore, considering that welded connections make the connections between the beams more robust, the front crossbeam 100, left longitudinal beam 200, rear crossbeam 300, and right longitudinal beam 400 are welded together in pairs to further ensure that the front subframe assembly 10 is less prone to deformation under external forces.

[0036] like Figure 3 As shown, in some embodiments, the left longitudinal beam 200 is modularly designed, including a left front bracket connected to the front crossbeam 100, a left rear bracket 230 connected to the rear crossbeam 300, and a left center bracket 220 connected to the left front and left rear brackets 230. It is easy to understand that dividing a large component like the left longitudinal beam 200 into multiple smaller bracket-like modules allows for the separate manufacture and assembly of each smaller module, thereby simplifying production and improving efficiency. In particular, when staff need to improve performance, only the smaller modules need to be modified, reducing the difficulty of upgrades and improvements.

[0037] In addition, such as Figure 1 As shown, the left-center bracket 220 is provided with a first mounting bracket 221, which is used to connect the compressor. It is easy to understand that the first mounting bracket 221 provides a dedicated mounting position for the compressor, ensuring the consistency of the compressor's position during each installation.

[0038] Furthermore, the first mounting bracket 221 is provided with two first positioning holes 223 spaced apart along the extension direction of the front crossbeam 100, and the left front bracket is provided with two second positioning holes 211 spaced apart along the extension direction of the front crossbeam 100. Both the first positioning holes 223 and the second positioning holes 211 are used to install the compressor. Based on the above-mentioned arrangement of the two first positioning holes 223 and the two second positioning holes 211, multi-point fixing can be achieved, making the compressor installation more secure and reducing the possibility of vibration and loosening.

[0039] Similar to the above, such as Figure 3 As shown, the right longitudinal beam 400 also features a modular design, including a right front bracket 410 connected to the front crossbeam 100, a right rear bracket 430 connected to the rear crossbeam 300, and a right center bracket 420 connected to the right front bracket 410 and the right rear bracket 430. Furthermore, both the left center bracket 220 and the right center bracket 420 are equipped with a second mounting bracket 610, and both the left front bracket and the right front bracket 410 are equipped with a third mounting bracket 630. Both the second mounting bracket 610 and the third mounting bracket 630 are used to mount the steering gear.

[0040] It should be noted that the second mounting bracket 610 and the third mounting bracket 630 are located on the same side, which allows for a compact installation of the steering gear, making full use of the limited space and improving space utilization. Additionally, it should be noted that the first mounting bracket 221 is located on one side of the left center bracket 220, and the second mounting bracket 610 is located on the other side of the left center bracket 220. These two brackets do not interfere with each other, ensuring that there is sufficient space for the installation of both the steering gear and the compressor.

[0041] Furthermore, considering cost savings and ease of manufacturing, the front crossbeam 100, left center bracket 220, rear crossbeam 300, and right center bracket 420 are all square tubes. Optionally, the left center bracket 220 and right center bracket 420 share a common square tube, which facilitates reducing the number of production molds and inspection tools, and significantly improves the utilization rate of parts materials. In addition, the shared square tube also has the characteristic of easy thickness adjustment. Based on this, the operator can simply adjust the thickness of the square tube to change the structural modes and stiffness of the front subframe assembly 10 without modifying other small modules. In addition, it should be noted that the right front bracket 410, right rear bracket 430, left front bracket, and left rear bracket 230 are functional brackets, and their design can be symmetrical or asymmetrical according to their functions.

[0042] Please refer to it again. Figure 2The connecting assembly 500 also includes connecting pieces 510 and fasteners. Furthermore, each connecting piece 510 corresponds to a connecting bracket 530 and is provided with a mounting hole. Based on the above, when the current subframe assembly 10 is used in a tram, the fasteners are used to mate with the mounting holes to connect the protective beam and the connecting bracket 530; when the current subframe assembly 10 is used in a diesel vehicle, the fasteners are used to mate with the mounting holes to connect the dowel bar and the connecting bracket 530. It is easy to understand that the mounting holes and fasteners ensure the stability of the connection and the accuracy of the position during installation of the protective beam or dowel bar.

[0043] Specifically, please refer to Figure 4 , Figure 4 Provided for this embodiment Figure 2 An enlarged schematic diagram of the structure at point A. In some embodiments, the mounting holes include first mounting holes 511 and second mounting holes 513 spaced apart along the extension direction of the front crossbeam 100, and the fasteners include first fasteners and second fasteners that respectively mate with the first mounting holes 511 and the second mounting holes 513.

[0044] In practical applications, specifically when the front subframe assembly 10 is used in a tram, the two first fasteners are respectively used to mate with the first mounting holes 511 of the two connecting pieces 510, so that the two connecting brackets 530 are respectively connected to both ends of the protective beam. When the front subframe assembly 10 is used in a gasoline vehicle, the first and second fasteners are respectively used to mate with the first mounting holes 511 and 513 of the same connecting piece 510, so that the connecting bracket 530 is connected to one end of the force transmission rod. It is easy to understand that the aforementioned first mounting holes 511 and second mounting holes 513 allow for adaptability in both gasoline and tram vehicles, further improving the versatility of the front subframe assembly 10.

[0045] In summary, this utility model provides a front subframe assembly 10, including a front crossbeam 100, a left longitudinal beam 200, a rear crossbeam 300, a right longitudinal beam 400, and a connecting assembly 500. The front crossbeam 100, left longitudinal beam 200, rear crossbeam 300, and right longitudinal beam 400 are interconnected in pairs to form a square frame. It is easy to understand that the square frame, as a closed structure, can absorb and disperse impact energy when subjected to external impact, improving the protection of internal components. Based on the above, the connecting assembly 500 includes two connecting brackets 530 respectively disposed on the left longitudinal beam 200 and the right longitudinal beam 400. When the front subframe assembly 10 is applied to an electric vehicle, the connecting brackets 530 are used to connect the protective beams to absorb and disperse impact energy during a collision, reducing damage to the battery pack. When the front subframe assembly 10 is used in a fuel vehicle, the connecting frame 530 is used to connect the force transmission rods. There are two force transmission rods, and they correspond one-to-one with the connecting frame 530. This can play a certain role in vibration isolation and help absorb some of the impact energy.

[0046] In addition, this utility model also provides a vehicle, specifically an electric vehicle or a gasoline vehicle. The vehicle includes a body and the front subframe assembly 10 described in the foregoing embodiments, and the body is connected to the front subframe assembly 10. Therefore, this vehicle can also absorb and disperse collision energy in the event of a collision, improving its impact resistance.

[0047] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
