目前,前副车架均通过螺栓紧固连接在车身上。在车辆发生碰撞时,发动机将向后产生较大位移并下落,从而将撞击力传递至前副车架上,并通过前副车架与车身的固定连接导致车身纵梁的变形并侵入乘员舱。这种安装结构通过螺栓受撞击断裂导致的前副车架与车身分离来降低车身纵梁的变形,从而减低乘员舱侵入伤害。但是,这种安装结构需要较大断裂应力才能达到前副车架与车身的分离,在降低车身纵梁撞击变形中作用有限。At present, the front sub-frames are fastened to the vehicle body by bolts. In the event of a collision of the vehicle, the engine will produce a large displacement and fall backwards, thereby transmitting the impact force to the front sub-frame, and the fixed connection between the front sub-frame and the vehicle body causes deformation of the longitudinal beam of the vehicle body and invades the passenger compartment. . This mounting structure reduces the deformation of the longitudinal beam of the vehicle body by separating the front subframe from the body caused by the impact fracture of the bolt, thereby reducing the intrusion of the passenger compartment. However, this installation structure requires a large breaking stress to achieve the separation of the front sub-frame and the body, and has a limited effect in reducing the impact deformation of the longitudinal beam of the vehicle body.

In other words, the first end of the first opening 10211 may be connected to the first end of the second opening 10221 through the third through hole 1026, and the second end of the first opening 10211 may pass through the third through hole 1026 and the second opening 1021. The two ends are connected.
第一开口10211的第一端与第二开口10221的第一端的间距可以小于螺杆1032的直径的一半,也就是说,连通第一通孔1021和第二通孔1022的开口的尺寸小于螺杆1032的半径,由此可以防止前副车架101在轻微前后晃动时螺栓103与安装支架102滑脱分离。也就是说,由于所述开口对螺杆的阻挡,可以防止前副车架101在轻微前后晃动时,螺杆1032从第一通孔1021脱出并移动到第二通孔1022。例如,在图7所示的结构形式中,第三通孔1026的横向尺寸小于螺杆1032的半径,这样,在轻微的前后晃动中,螺栓103并不会从第一通孔1021中脱出并移动到第二通孔1022,而当车辆发生碰撞受到较大的力时,螺杆将克服第三通孔的阻挡,从第一通孔1021中脱出并移动到第二通孔1022。The distance between the first end of the first opening 10211 and the first end of the second opening 10221 may be less than half of the diameter of the screw 1032, that is, the size of the opening connecting the first through hole 1021 and the second through hole 1022 is smaller than the screw The radius of 1032, thereby preventing the bolt 103 from slipping off the mounting bracket 102 when the front subframe 101 is slightly rocked back and forth. That is, due to the blocking of the screw by the opening, it is possible to prevent the screw 1032 from coming out of the first through hole 1021 and moving to the second through hole 1022 while the front sub-frame 101 is slightly swayed back and forth. For example, in the structural form shown in FIG. 7, the lateral dimension of the third through hole 1026 is smaller than the radius of the screw 1032, so that the bolt 103 does not come out and move from the first through hole 1021 in a slight front and rear sway. To the second through hole 1022, when the vehicle collides with a large force, the screw will overcome the blocking of the third through hole, and will be disengaged from the first through hole 1021 and moved to the second through hole 1022.
有利地,如图1-图5所示,前副车架101可以包括前副车架本体1011和套管1012,套管1012可以设在前副车架本体1011上,螺杆1032可以与套管1012相连。由此可以使前副车架及安装支架总成10的结构更加合理。Advantageously, as shown in FIGS. 1-5, the front sub-frame 101 may include a front sub-frame body 1011 and a sleeve 1012. The sleeve 1012 may be disposed on the front sub-frame body 1011, and the screw 1032 may be coupled to the sleeve. 1012 connected. Thereby, the structure of the front sub-frame and the mounting bracket assembly 10 can be made more reasonable.
具体而言,螺杆1032的下部可以向下穿过前副车架本体1011,螺母105可以螺纹配合在螺杆1032的下部且螺母105可以抵靠在前副车架本体1011的下表面上。也就是说,螺栓103可以从上向下安装,即螺栓103在上,螺母105在下。In particular, the lower portion of the screw 1032 can pass down through the front subframe body 1011, the nut 105 can be threaded onto the lower portion of the screw 1032 and the nut 105 can abut against the lower surface of the front subframe body 1011. That is, the bolt 103 can be mounted from the top down, that is, the bolt 103 is on, and the nut 105 is down.
如图1、图3-图5所示,螺帽1031可以包括螺帽本体10311和裙边10312,裙边
10312可以设在螺帽本体10311的周面上。其中,在所述安装位置裙边10312可以抵靠在安装支架102上,裙边10312的外径可以大于第一通孔1021的直径且裙边10312的外径可以小于第二通孔1022的直径。第一通孔1021和第二通孔1022都可以是圆孔。由此可以使螺帽本体10311为多角形螺帽本体(例如六角形螺帽本体),从而可以更加方便地、容易地将螺栓103安装在前副车架101和安装支架102上。As shown in FIG. 1 and FIG. 3 to FIG. 5, the nut 1031 may include a nut body 10311 and a skirt 10312, and a skirt
10312 may be provided on the circumferential surface of the nut body 10311. Wherein, the skirt 10312 can abut against the mounting bracket 102 at the mounting position, the outer diameter of the skirt 10312 can be larger than the diameter of the first through hole 1021 and the outer diameter of the skirt 10312 can be smaller than the diameter of the second through hole 1022. . Both the first through hole 1021 and the second through hole 1022 may be circular holes. Thereby, the nut body 10311 can be a polygonal nut body (for example, a hexagonal nut body), so that the bolt 103 can be more easily and easily mounted on the front sub-frame 101 and the mounting bracket 102.

Since the elastic force exerted on the nut 1031 by the elastic member 104 is downward, not only the elastic member 104 can be used to press the bolt 103 to prevent the bolt 103 from rotating, but also the friction between the bolt 103 and the mounting bracket 102 can be increased to prevent the front pair. When the frame 101 is slightly swayed back and forth, the bolt 103 is detached from the mounting bracket 102.
