[0026] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0027] Reference below Figure 1-Figure 4 A vehicle frame according to an embodiment of the utility model is described, and the utility model also provides a vehicle.

[0028] Reference Figure 1-4 As shown, the frame of the embodiment of the utility model includes: a frame body 10 and two mounting brackets 20.

[0029] The frame body 10 includes: a plurality of cross beams 11 and two longitudinal beams 12. The plurality of cross beams 11 are arranged in parallel. The two longitudinal beams 12 are respectively arranged at the two ends of the plurality of cross beams 11. The cross beams 11 are fixedly connected to the longitudinal beams 12. Specifically, the design of the frame is mainly to support and connect specific components and enhance the stability and rigidity of the overall structure of the vehicle. The frame body is composed of a plurality of cross beams 11 and two longitudinal beams 12. The plurality of cross beams 11 are parallel to each other. Two longitudinal beams 12 are arranged on both sides of the cross beams 11. The longitudinal beams 12 are fixedly connected to the front edge of each cross beam 11.

[0030] The longitudinal beam 12 is a long strip structure along the longitudinal direction of the vehicle, which can serve as one of the main load-bearing structures of the vehicle chassis, bearing the static and dynamic loads of the vehicle, including the weight of the vehicle body, engine, suspension system and other accessories, reducing the deformation of the vehicle when turning or driving on uneven roads, and maintaining the structural integrity of the vehicle body. The cross beam 11 extends in the lateral direction of the vehicle, is responsible for lateral support of the chassis structure, bears lateral static and dynamic loads, ensures that the vehicle body does not deform excessively during driving, and provides additional support, especially when the vehicle is subjected to lateral forces.

[0031] The two mounting brackets 20 are respectively fixed below the two longitudinal beams 12. Two mounting portions 211 are arranged at intervals on the mounting brackets 20. The two mounting portions 211 are respectively used to mount the first longitudinal tie rod and the second longitudinal tie rod. Specifically, the first longitudinal tie rod can be a long longitudinal tie rod, and the second longitudinal tie rod can be a short longitudinal tie rod, or the first longitudinal tie rod is a short longitudinal tie rod, and the second longitudinal tie rod is a long longitudinal tie rod.

[0032] The long and short trailing rods are part of the suspension system and are usually used to support and connect the vehicle's suspension components, such as suspension arms or longitudinal control arms. The long trailing rod is mainly used to stabilize and locate the position of the wheels, control the movement of the wheels in the longitudinal direction, help maintain the stability and handling of the vehicle, and provide support in situations such as acceleration, braking and cornering. The short trailing rod is mainly used to control the movement of the wheels in the lateral direction. It helps to maintain the balance of the vehicle, especially when turning, to ensure that the vehicle is stable and the direction is controlled.

[0033] In the embodiment of the utility model, the installation positions of the short longitudinal tie rod and the long longitudinal tie rod are both located on the mounting bracket 20, and the mounting bracket 20 is designed to be below the longitudinal beam 12, which is equivalent to making the long and short longitudinal tie rod mounting bracket 20 structure into an integrated structure, thereby enhancing the strength of the long and short longitudinal tie rod mounting bracket 20, and at the same time increasing the lateral lap size between the mounting bracket 20 and the longitudinal beam 12, thereby improving the lateral load bearing capacity of the mounting bracket 20 and reducing the problem of cracking in the later stage.

[0034] Therefore, by setting two mounting parts 211, the mounting bracket of the first longitudinal tie rod and the mounting bracket of the second longitudinal tie rod are made into an integrated structure, which can enhance the strength of the mounting bracket 20, while increasing the lateral overlap size between the mounting bracket 20 and the longitudinal beam 12, thereby improving the lateral load bearing capacity of the mounting bracket 20 and reducing the problem of cracking in the later stage.

[0035] Reference Figure 1-4 As shown, the mounting bracket 20 includes: a bracket body 21 and a first mounting plate 22. The bracket body 21 is fixedly connected to the longitudinal beam 12 and two mounting portions 211 are arranged on the bracket body 21. The first mounting plate 22 is fixed to the bracket body 21 and a space for accommodating the first longitudinal tie rod and the second longitudinal tie rod is defined between the bracket body 21. That is, the mounting bracket 20 is composed of the bracket body 21 and the first mounting plate 22. The bracket body 21 is fixedly connected to the longitudinal beam 12. The mounting portion 211 for installing the first longitudinal tie rod and the second longitudinal tie rod is arranged on the bracket body 21, so that the first longitudinal tie rod and the second longitudinal tie rod can be fixed on the longitudinal beam 12. The first mounting plate 22 contacts the outside and is fixed on the bracket body 21. There is a gap between the first mounting plate 22 and the bracket body 21, which can accommodate the first longitudinal tie rod and the second longitudinal tie rod.

[0036] Reference Figure 1-4As shown, the bracket body 21 is provided with two first mounting openings 212, two mounting sleeves 213 are respectively provided in the two first mounting openings 212, and two mounting portions 211 are respectively provided on the two mounting sleeves 213. That is, the mounting sleeves 213 are provided on the bracket body 21, and the first longitudinal tie rod and the second longitudinal tie rod are installed in the mounting portion 211 through the mounting sleeves 213. The use of the mounting sleeves 213 to install the first longitudinal tie rod and the second longitudinal tie rod can increase the installation speed, save time and physical strength, and the mounting sleeves 213 are easy to operate and have good installation consistency, which is suitable for large-scale production.

[0037] Moreover, the mounting sleeve 213 is disposed in the first mounting opening 212 of the bracket body 21 , and the connection method may be welding, which can enhance the strength of the bracket body 21 and reduce the problem of cracking of the mounting bracket 20 .

[0038] Reference Figure 3 As shown, the front end and / or rear end of the bracket body 21 are provided with a weakened arc surface 214, and the weakened arc surface 214 is recessed toward the mounting sleeve 213. Specifically, the front end and rear end of the bracket body 21 along the longitudinal beam 12 are provided with a weakened arc surface 214, that is, a portion of the bracket body 21 in the direction of the mounting sleeve 213 is recessed inward to form the weakened arc surface 214, and the stress distribution is adjusted by partially weakening the cross section of the bracket body 21, thereby reducing the stress of the weld at the end of the overlap between the bracket body 21 and the longitudinal beam 12, improving the durability of the weld and the fatigue life of the bracket body 21, and avoiding the occurrence of cracking problems in the later period.

[0039] Reference Figure 3 As shown, the cross-sectional area of ​​the bracket body 21 gradually decreases in the direction away from the longitudinal beam 12. Specifically, the cross-sectional area of ​​the bracket body 21 at one end away from the longitudinal beam 12 gradually decreases, which can reduce the overall weight and space occupancy of the bracket body 21, improve the fuel economy of the vehicle, or make the structure stronger at the position where strength is required. On the other hand, reducing the cross-sectional area can balance the stress distribution of the bracket body 21, alleviate stress concentration, and improve the durability and fatigue life of the structure.

[0040] Reference Figure 3-4 As shown, the vehicle frame further includes: a fastener, two second mounting openings 221 are arranged at intervals on the first mounting plate 22, the two second mounting openings 221 correspond to the two mounting sleeves 213 respectively, and the fastener is fixedly connected with the mounting sleeves 213 after passing through the second mounting openings 221. In other words, the second mounting opening 221 of the first mounting plate 22 contacts the fastener, and the side facing the bracket body 21 corresponds to the position of the two mounting sleeves 213, and the fastener first passes through the second mounting opening 221 on the first mounting plate 22, and then is fixedly connected with the mounting sleeves 213 in the first mounting opening 212, thereby fixing the first longitudinal tie rod and the second longitudinal tie rod on the mounting bracket 20.

[0041] Reference Figure 3 As shown, at least two mounting flanges 23 are arranged at intervals at the edge of the first mounting plate 22, the mounting flanges 23 are folded relative to the edge of the first mounting plate 22, and the mounting flanges 23 are fixedly connected to the bracket body 21. The mounting flanges 23 can improve the edge structural strength of the first mounting plate 22, avoid edge deformation or cracks, and the mounting flanges 23 are fixedly connected to the bracket body 21, which can increase the surface area connected to the bracket body 21 and improve the strength and stability of the connection.

[0042] Reference Figure 3 As shown, at least two weight-reducing holes 222 are arranged at intervals on the first mounting plate 22. By providing the weight-reducing holes 222, the overall weight of the mounting bracket 20 can be reduced while maintaining sufficient structural strength, so that the vehicle can obtain better fuel economy and higher performance.

[0043] There may be three, four or more weight-reducing holes 222 , and the shape of the weight-reducing holes 222 may be circular, elliptical, rectangular or other special shapes.

[0044] Reference Figure 3 As shown, the bracket body 21 includes two second mounting plates 215, which are buckled relative to each other and connected to each other, and the two second mounting plates 215 are respectively fixedly connected to the longitudinal beam 12. The two mounting plates are buckled to each other to form the main part of the bracket body 21, and the bracket body 21 and the first longitudinal tie rod and the second longitudinal tie rod fixedly connected to the frame body can be fixed on the longitudinal beam 12 through the two second mounting plates 215 respectively being fixedly connected to the longitudinal beam 12.
