[0028] 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.

[0029] The following is for reference. Figures 1-7 This invention describes a vehicle frame integrated support according to an embodiment of the present invention.

[0030] like Figures 1-7 As shown, the frame integrated support 100 includes: a suspension mounting part 1 and a tow hook mounting part 2.

[0031] The tow hook mounting part 2 is located on one side of the suspension mounting part 1 along the left-right direction of the vehicle, and the side of the tow hook mounting part 2 away from the suspension mounting part 1 along the left-right direction of the vehicle is used to connect to the outer side of the longitudinal beam 200 of the frame.

[0032] Specifically, the suspension mounting part 1 and the tow hook mounting part 2 are connected along the left-right direction of the vehicle, and the tow hook mounting part 2 is located on the inner side of the suspension mounting part 1 along the left-right direction of the vehicle, so that the inner side of the tow hook mounting part 2 along the left-right direction of the vehicle can be connected to the outer side of the frame longitudinal beam 200. The inner side of the tow hook mounting part 2 along the left-right direction of the vehicle can fit snugly against the outer side of the frame longitudinal beam 200 to increase the connection strength between the two, thereby ensuring a reliable connection between the frame integrated support 100 and the frame longitudinal beam 200. It should be noted that the inner side in the left-right direction of the vehicle refers to the side closer to the vehicle / frame longitudinal beam 200 along the left-right direction, and the outer side in the left-right direction of the vehicle refers to the side farther away from the vehicle / frame longitudinal beam 200 along the left-right direction.

[0033] Therefore, compared to the separate arrangement of tow hook brackets and suspension brackets in the prior art, the integrated frame support 100 of this utility model effectively reduces the types of parts and the weight of the frame assembly by integrating the suspension mounting part 1 for mounting the suspension and the tow hook mounting part 2 for mounting the tow hook 400 into one unit, while meeting the requirement of small space requirements. Furthermore, by arranging the tow hook mounting part 2 on the outer side of the frame longitudinal beam 200, the special requirements of low-entry trucks are met by arranging the outer side of the frame longitudinal beam 200, representing an integrated optimization and improvement compared to the separate arrangement of the tow hook mounting bracket on the inner side of the frame longitudinal beam 200.

[0034] According to some embodiments of the present invention, the tow hook mounting part 2 includes a main board part 21 and a protrusion part 22. The main board part 21 is connected to the outer side of the longitudinal beam 200 of the vehicle frame on one side along the left-right direction of the vehicle. The protrusion part 22 is formed on the other side of the main board part 21 along the left-right direction of the vehicle, and a tow hook mounting hole 23 is formed at one end of the protrusion part 22 along the front-rear direction of the vehicle.

[0035] refer to Figures 2-7 As shown, the main board 21 is attached to the outer side of the frame longitudinal beam 200 along the left-right direction of the vehicle. The main board 21 has a protrusion 22 on the outer side along the left-right direction of the vehicle. A trailer hitch mounting hole 23 is formed at one end of the protrusion 22 along the front-rear direction of the vehicle, so that one end of the trailer hitch 400 extends into the trailer hitch mounting hole 23 along the front-rear direction of the vehicle for fixing.

[0036] Furthermore, one end of the protrusion 22 along the vehicle's longitudinal direction is flush with one end of the main board portion 21 along the vehicle's longitudinal direction, and the end of the protrusion 22 along the vehicle's longitudinal direction forms a trailer hitch mounting hole 23. This arrangement allows the trailer hitch 400 to be quickly inserted into the trailer hitch mounting hole 23 during installation, ensuring that the usable length of the trailer hitch 400 is not significantly affected. Additionally, the length of the protrusion 22 along the vehicle's longitudinal direction needs to be designed based on the range of mating lengths between the trailer hitch 400 and the trailer hitch mounting hole 23. In this embodiment of the invention, the length of the protrusion 22 along the vehicle's longitudinal direction is approximately half the length of the main board portion 21 along the vehicle's longitudinal direction, thus satisfying the current mating length requirements between the trailer hitch 400 and the trailer hitch mounting hole 23.

[0037] According to some embodiments of the present invention, the main board portion 21 has a plurality of frame mounting holes 24 arranged at intervals along the front-rear direction and / or the up-down direction of the vehicle on the side opposite to the protrusion portion 22 in the left-right direction of the vehicle.

[0038] refer to Figures 4-5 As shown, the main board portion 21 has a plurality of frame mounting holes 24 formed on its inner side along the left-right direction of the vehicle. The plurality of frame mounting holes 24 are used to mate with the through holes on the frame longitudinal beam 200 for fixed connection using fasteners such as bolts and nuts. Furthermore, the plurality of frame mounting holes 24 are arranged at intervals along the front-rear direction and / or the vertical direction of the vehicle to provide a sufficient number of mounting points for the frame longitudinal beam 200 and the tow hook mounting portion 2 to connect to each other.

[0039] Specifically, in this example, the main board portion 21 has eight frame mounting holes 24 formed on the inner side along the left-right direction of the vehicle. Every four frame mounting holes 24 are arranged in a row along the front-rear direction of the vehicle and in two rows along the vertical direction of the vehicle.

[0040] According to some embodiments of the present invention, the main board portion 21 has a plurality of weight-reducing grooves 25 formed on the side away from the protrusion 22 along the left-right direction of the vehicle, at a position avoiding the frame mounting hole 24, and each pair of adjacent weight-reducing grooves 25 is separated by a rib 26.

[0041] refer to Figures 4-5 As shown, the main board 21 has multiple weight-reducing grooves 25 formed on the inner side along the left and right direction of the vehicle, except for the circumference of the frame mounting hole 24. A rib 26 is provided between each two adjacent weight-reducing grooves 25. This allows for weight reduction without significantly changing the structural strength of the main board 21, thus achieving a lightweight design for the frame integrated support 100.

[0042] Specifically, in this example, larger weight-reducing grooves 25 are formed between the first row of frame mounting holes 24 and the second row of frame mounting holes 24 on the main board 21, and between the second row of frame mounting holes 24 and the bottom of the main board 21. Smaller weight-reducing grooves 25 are also formed between two adjacent frame mounting holes 24 in each row of frame mounting holes 24. The depth of the weight-reducing grooves 25 is shallower than that of the larger weight-reducing grooves 25, so as to ensure the structural strength and durability of the outer wall of the frame mounting holes 24.

[0043] According to some embodiments of the present invention, the protrusion 22 is constructed as an arched protrusion structure, and the trailer hook mounting hole 23 is formed at the center of one end of the arched protrusion structure along the vehicle's front-rear direction.

[0044] refer to Figure 2 , Figure 3 and Figure 7 As shown, the main board portion 21 has an arched protrusion structure formed on the outer side along the left-right direction of the vehicle. Utilizing the high strength of the arched protrusion structure, the strength and durability of the protrusion portion 22 are ensured. Furthermore, the arched protrusion structure allows for a smooth transition connection with the main board portion 21, effectively avoiding stress concentration problems, thereby further improving the strength and durability of the protrusion portion 22. This, in turn, enhances the connection reliability and service durability between the trailer hitch 400 and the trailer hitch mounting portion 2.

[0045] According to some embodiments of the present invention, the suspension mounting part 1 includes a main body 11 and a tube body 12. The main body 11 extends along the left-right direction of the vehicle, and one side of the main body 11 along the left-right direction of the vehicle is connected to the tow hook mounting part 2. The lower end of the main body 11 is used to fix it to the vehicle frame assembly. The main body 11 extends upward along the other side along the left-right direction of the vehicle and is connected to the tube body 12. The tube body 12 has a through suspension mounting hole 13 along the left-right direction of the vehicle.

[0046] In this configuration, the main body 11 extends along the left-right direction of the vehicle. The tow hook mounting part 2 is connected to the inner side of the main body 11 along the left-right direction of the vehicle, and the main body 11 extends outward along the left-right direction of the vehicle and is connected to the tube body 12. The tube body 12 has a through suspension mounting hole 13 along the left-right direction of the vehicle for mounting the suspension and bushing 300.

[0047] According to some embodiments of the present invention, the main body 11 extends horizontally along the side of the vehicle near the tow hook mounting part 2 to form a first connecting part 14, and a second connecting part 15 is connected above the first connecting part 14. The cross-sectional area of ​​the second connecting part 15 gradually increases from the side away from the tow hook mounting part 2 to the other side.

[0048] refer to Figure 3As shown, the main body 11 extends horizontally towards the tow hook mounting part 2 along the inner side in the left-right direction of the vehicle to form a first connecting part 14. A second connecting part 15 is connected above the first connecting part 14. The cross-sectional area of ​​the second connecting part 15 gradually increases from the side away from the tow hook mounting part 2 to the side closer to the tow hook mounting part 2, resembling a diagonal triangular structure. This arrangement, relying on the first connecting part 14 and the second connecting part 15 to connect to one side of the tow hook mounting part 2, effectively ensures the reliability of the connection between the tow hook mounting part 2 and the suspension mounting part 1 by increasing the connection area of ​​the main body 11 for connecting to the tow hook mounting part 2. Furthermore, the second connecting part 15 allows for a smooth transition connection with the tow hook mounting part 2, effectively avoiding stress concentration problems.

[0049] According to some embodiments of this utility model, the integrated frame support 100 is a one-piece molded structure. This design eliminates the connection points found in traditional splicing or welding processes, avoiding stress concentration issues caused by seams or welds, thereby improving the overall structural strength and durability. Furthermore, due to its integrated design, the load can be distributed more evenly across the entire support, reducing the risk of localized overload. In addition, compared to traditional split supports that may fail due to loose connections, corrosion, or fatigue fracture, the one-piece integrated frame support 100 eliminates these potential weaknesses, significantly improving product reliability, resulting in a longer service life and lower maintenance costs.

[0050] In some embodiments, the frame integrated support 100 of this embodiment is formed into an integral structure using a casting process. Specifically, it can be cast using a sand-coated iron mold process. Because the frame integrated support 100 of this utility model integrates a suspension mounting part 1 and a tow hook mounting part 2, the frame integrated support 100 has a smaller volume and a simpler structure. Therefore, the integral molding process effectively ensures the structural strength and durability of the frame integrated support 100, while simplifying the process and improving installation efficiency.

[0051] According to a second aspect embodiment of the present invention, a vehicle frame assembly includes: a longitudinal beam 200; a suspension mount; a tow hook 400; and a frame integrated support 100. The frame integrated support 100 is connected to the outer side of the longitudinal beam 200 via a tow hook mounting portion 2. The suspension mount is mounted on the suspension mounting portion 1, and the tow hook 400 is mounted on the tow hook mounting portion 2. The vehicle frame assembly also includes a crossbeam reinforcement 500, which allows the lower end of the suspension mounting portion 1 to be fixedly connected to the crossbeam reinforcement 500, further improving the reliability of the connection between the frame integrated support 100 and the vehicle frame assembly.

[0052] The vehicle according to a third aspect of the present invention includes a frame assembly.
