Description

Technical Field

[0001] The utility model is used in the field of automobiles, and particularly relates to a mounting structure of a mounting bracket, a subframe and a vehicle. Background Art

[0002] The subframe is an important part of the front and rear axles of an automobile. It is mainly used to support the front and rear axles and the suspension system. At the same time, it can also reduce the vibration and noise during the driving of the automobile. The main sources of vibration and noise are the engine or the motor. The connection bridge between the subframe and the engine or the motor is the mount. The mount filters and absorbs the vibration and noise generated by the engine or the motor, minimizing the noise interference transmitted to the subframe and then to the cockpit. The combination form of the mount and the subframe is crucial for the vehicle NVH;

[0003] Generally speaking, there are two combination forms: the mount is bolt-assembled to the subframe through a mounting bracket, and the mount is welded to the subframe through a mounting bracket; the commonly used bolt connection on the market is a two-point connection, that is, the mounting bracket is fixed on the subframe through two bolts. This method results in insecure bolt fastening, and due to the shape of the bolt mounting seat, the upper end strength of the mounting bracket is insufficient, and there is a high risk of loosening and breaking; although the other welding method can increase the connection strength between the mounting bracket and the subframe, due to the long weld seam, it is not easy to control the welding deformation amount, which will also lead to unstable welding strength of the product and high production costs. If defective products flow into the market, it is very easy to have loosening and breaking at the weld seam position, which will affect the driving safety of the whole vehicle.

[0027] See Figures 1 - 4 , an embodiment of the present utility model provides a mounting structure for a suspension bracket, including a subframe beam 100, a suspension bracket 200, and bolts (not shown). The subframe beam 100 is provided with a suspension bracket mounting surface 101 and a plurality of sleeve mounting holes extending from the suspension bracket mounting surface 101 to the back side of the subframe beam 100. The sleeve mounting holes can be through holes or blind holes. A sleeve 102 is provided in the sleeve mounting holes, and the sleeve 102 is embedded in the sleeve mounting holes. The inner wall of the sleeve 102 is provided with internal threads. The suspension bracket 200 is provided with a plurality of bolt holes 201 corresponding to the sleeve mounting holes. The suspension bracket 200 is arranged on the suspension bracket mounting surface 101. The bolts pass through the bolt holes 201 and are connected to the internal threads of the sleeve 102, and the suspension bracket 200 is firmly connected to the subframe beam 100.

[0028] Although the existing assembly method also uses bolt fastening, it has the following disadvantages: usually using bolt fastening, the fastening strength is insufficient. In order to improve the strength of the mounting seat, the shape design size of the mounting seat is relatively large, resulting in no connecting device between the mounting seat and the suspension bracket 200, and there is a high risk that the upper end is weak in strength and the lower end is strong in strength. Eventually, there is a safety hazard that the suspension bracket 200 swings left and right or even loosens and breaks.

[0029] In the technical solution of the present utility model, by arranging a sleeve 102 in the sleeve mounting hole of the subframe beam 100, and further using bolts to connect the internal threads provided in the sleeve 102 to tightly connect the suspension bracket 200 to the subframe beam 100, ensuring the tight connection between the suspension bracket 200 and the subframe beam 100, which is very convenient for the later maintenance and replacement of the suspension bracket 200. The technical solution of the present utility model optimizes the structure on the basis of the existing bolt assembly method. With the cooperation connection between the sleeve 102 and the bolts, it ensures the improvement of the assembly strength and the structural strength, and also has great advantages in the management of part costs.

[0030] In some embodiments, referring to Figure 4 , the sleeve mounting hole is a through hole that penetrates from the suspension bracket mounting surface 101 to the back side of the subframe beam 100. The subframe beam 100 can be a hollow beam. The sleeve 102 extends from the first end to the second end along the length direction. The first end of the sleeve 102 penetrates into the sleeve mounting hole from the back side of the subframe beam 100, and the first end of the sleeve 102 is flush with the suspension bracket mounting surface 101. The second end of the sleeve 102 is provided with a flange 103 that abuts against the back side of the subframe beam 100. The two ends of the sleeve 102 are welded to the subframe beam 100. Through the flange 103, the depth of the sleeve 102 inserted into the sleeve mounting hole can be accurately controlled, ensuring that the first end of the sleeve 102 does not protrude from the suspension bracket mounting surface 101 while ensuring the welding with the subframe beam 100.

[0031] Furthermore, referring to Figure 4 , the sleeve 102 is provided with internal threads on one side close to the second end, making the connection position between the bolt and the sleeve 102 farther away from the suspension bracket 200, further improving the installation stability of the suspension bracket 200 on the subframe beam 100.

[0032] In some embodiments, referring to Figures 1 - 4 , the suspension bracket 200 includes a bottom plate 202. The bottom plate 202 is arranged on the suspension bracket mounting surface 101. The bottom plate 202 is provided with a plurality of bolt holes 201, and the bolt holes 201 penetrate through the bottom plate 202 along the thickness direction of the bottom plate 202.

[0033] Furthermore, referring to Figures 1 - 4, a first support plate 203 and a second support plate 204 are provided on the top of the bottom plate 202. A suspension mounting groove 205 is formed between the first support plate 203 and the second support plate 204. The suspension can be connected to the subframe beam 100 through the suspension mounting groove 205. The bottom plate 202 forms a first support portion 206 on the side of the first support plate 203 away from the second support plate 204, and the bottom plate 202 forms a second support portion 207 on the side of the second support plate 204 away from the first support plate 203. Among them, the bolt holes 201 include a first bolt hole provided on the first support portion 206, a second bolt hole and a third bolt hole provided on the second support portion 207. In this embodiment, a total of three bolt holes 201 can be provided. The three bolt holes 201 are staggered on the suspension bracket mounting surface 101, providing three locking and positioning points for the suspension bracket 200, fully ensuring the stability of the suspension bracket 200 on the subframe beam 100.

[0034] In some embodiments, refer to Figures 1 - 4 , the suspension bracket 200 is provided with a first reinforcing rib 208 and a second reinforcing rib 209. The first reinforcing rib 208 is obliquely supported between the first support portion 206 and the first support plate 203, and the first reinforcing rib 208 is obliquely supported between the second support portion 207 and the second support plate 204. The first reinforcing rib 208 is provided with an avoidance hole at the corresponding position of the first bolt hole, and the second reinforcing rib 209 is provided with avoidance holes at the corresponding positions of the second bolt hole and the third bolt hole. In this embodiment, by adding reinforcing ribs between the bottom plate 202 and the support plate and hollowing out the reinforcing ribs to avoid bolts, not only can the weight of the suspension bracket 200 be optimized, but also the connection strength between the bottom plate 202 and the support plate can be significantly improved, solving the potential problems of loosening and fracture.

[0035] In some embodiments, refer to Figure 1 , Figure 4 , the first support plate 203 and the second support plate 204 are provided with opposite mounting holes 210. A nut is provided on the side wall surface of the first support plate 203 away from the second support plate 204. After the suspension is installed in the suspension mounting groove 205, it can be connected to the suspension bracket 200 through a transverse bolt. When connecting, the bolt is inserted into the mounting hole 210 from one side and then locked to the nut on the other side. Among them, the nut is installed on the second support plate 204 through a nut box 211. The nut box 211 is sleeved outside the nut and fixedly connected to the first support plate 203. The nut box 211 and the nut cooperate with each other to limit the rotation of the nut.

[0036] In some embodiments, refer to Figure 1 , Figure 2 , Figure 3, the subframe beam 100 includes a cross beam 104 and a vehicle body mounting bracket 105 disposed at the end of the cross beam 104. The vehicle body mounting bracket 105 has a flange 106 extending to the outer wall surface of the cross beam 104. The flange 106 is welded to the outer wall surface of the cross beam 104, effectively improving the connection strength between the vehicle body mounting bracket 105 and the cross beam 104. Further, a bottom plate 202 is disposed on the outer wall surface of the cross beam 104 and thinned at a position corresponding to the flange 106, so as to further optimize the structure and reduce weight while ensuring strength.
