The support 2 is annularly arranged on the first mounting seat 141 and the second mounting seat 142, so that local structures on the peripheral sides of the mounting points can be reinforced, and the maximum improvement of the performance of the original dynamic stiffness of the suspension mounting position can be realized.
In particular, the support 2 comprises a ring-shaped stay 21 looped around the mounting structure 14. The support member 2 may be rod-shaped, block-shaped, or plate-shaped, and may be fixed to the upper plate 11 and the lower plate 12 to support the upper plate and the lower plate, so that the effect of improving the torsional mode may be achieved, and therefore, the present invention is not limited thereto. However, in this embodiment, the annular supporting plate 21 is selected as the supporting member 2, so that the structure is small, the thickness is small, the weight is increased less, but the related performance can still be greatly improved, and the lightweight design of the whole vehicle is facilitated.
Further, at least one end of the upper end or the lower end of the annular supporting plate 21 extends inwards or outwards to form a first flanging structure 211, and the first flanging structure 211 is used for being attached and fixed to the main body 1. In order to facilitate the connection of the ring-shaped supporting plate 21 to the main body 1 during the installation of the ring-shaped supporting plate 21, the ring-shaped supporting plate 21 should be welded to the upper plate 11 or the lower plate 12 first, and then the upper plate 11 should be welded to the lower plate 12, so as to facilitate the positioning and welding operation of the ring-shaped supporting plate 21. Therefore, in the present embodiment, the first flanging structure 211 is disposed on the ring-shaped supporting plate 21 to facilitate the pre-connection of the ring-shaped supporting plate 21 to the upper plate 11 or the lower plate 12, specifically, the first flanging structure 211 can support the ring-shaped supporting plate 21 to be positioned on the upper plate 11 or the lower plate 12 when not being welded, on the one hand, and on the other hand, the first flanging structure 211 can increase the joint area between the ring-shaped supporting plate 21 and the upper plate 11 or the lower plate 12, thereby facilitating the welding operation and having higher welding strength. In this embodiment, because the groove 121 is formed in the lower plate 12, the annular supporting plate 21 needs to be attached to the groove 121, so that the difficulty of the flanging structure arranged at the lower end of the annular supporting plate 21 is increased, the first flanging structure 211 is arranged at the upper end of the annular supporting plate 21 and is fixedly connected to the upper plate 11, the first flanging structure 211 is convenient to arrange, and the manufacturing difficulty of the annular supporting plate 21 is reduced so as to reduce the production cost. In addition, first turn-ups structure 211 can extend the setting inwards or outwards, all can realize above effect, and the concrete mode of setting up the basis the concrete structure of upper plate 11 adopts the mode of being convenient for operate can, does not do the restriction here.
In addition, a side portion 111 extends downwards from one side of the upper plate 11 close to the mounting structure 14, the side portion 111 is abutted and fixed with the lower plate 12, the ring-shaped supporting plate 21 is abutted and fixed with the side portion 111, a second flanging structure 212 extends laterally from the abutting portion of the ring-shaped supporting plate 21 and the side portion 111, and the second flanging structure 212 is used for being attached and fixed to the side portion 111. The side portion 111 may be provided to increase a connection point of the upper plate 11 and the lower plate 12 to increase the structural strength of the body 1. On the basis, the ring-shaped supporting plate 21 is provided with the second flanging structure 212 for attaching to the side portion 111, and for the reason similar to that of the first flanging structure 211, the second flanging structure 212 is used for pre-positioning and fixing the ring-shaped supporting plate 21, and the flanging arrangement can facilitate the welding operation and has higher welding strength. Meanwhile, the first flanging structure 211 and the second flanging structure 212 are arranged together, so that the local structural strength of the supporting part of the annular supporting plate 21 and the overall torsional mode of the main body 1 are further increased.
In addition, a plurality of through holes 213 are formed in the annular supporting plate 21. The annular supporting plate 21 supports the upper plate 11 and the lower plate 12, and is added on the basis of the local structure of the main body 1 and the lifting torsion mode, the annular supporting plate 21 is further lightened, and the lightweight design of the whole vehicle is realized. Therefore, in the present embodiment, the through holes 213 are formed in the ring-shaped supporting plate 21 to reduce the weight of the ring-shaped supporting plate 21, and the through holes are convenient for manufacturing and have low production cost.
On the other hand, the connecting member 3 includes a connecting plate 31, and both ends of the connecting plate 31 are attached to and fixed to the lower plate 12. Based on with support piece 2 is similar reason, connecting piece 3 also can set up to shaft-like, cubic etc. but in this embodiment connecting piece 3 sets up to connecting plate 31, on the one hand connecting plate 31 with the laminating area of hypoplastron 12 is big, and the welding operation of being convenient for and welding are firm, and on the other hand panel spare sets up that the structure is little and thickness is thin, and it is few to increase weight, can realize the lightweight design of whole car on the basis of promoting relevant performance.
Further, the two sides of the connecting plate 31 extend downwards to form third flange structures 311. The third flanging structures 311 are arranged on two sides of the connecting plate 31, so that the structural strength of the connecting plate 31 is increased, the deformation of the connecting plate is inhibited, the service life of the connecting plate is prolonged, and the compression strength and the tensile strength of the connecting plate are increased, so that the torsion mode of the lower plate 12 is further improved.
Still further, two ends of the groove 121 in the length direction are respectively provided with one of the connecting members 3. Two connecting pieces 3 are arranged at two ends of the groove 121, the connecting pieces 3 are symmetrically arranged, and it is conceivable that the connecting pieces 3 are more in number, so that the structural strength of the main body 1 and the capacity of improving the torsion mode of the main body are stronger, but the lightweight design of the whole vehicle is considered, in the embodiment, the connecting pieces 3 are arranged into two, and the two requirements are considered.
The above only be the preferred embodiment of the utility model discloses a not consequently restriction the patent scope of the utility model, all be in the utility model discloses a under the design, utilize the equivalent structure transform of what the content of the description and the attached drawing was done, or direct/indirect application all includes in other relevant technical field the utility model discloses a patent protection is within range.
