Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a front crossbeam assembly. Background Art

[0002] The front cross beam assembly of the automobile is located in front of the left and right front longitudinal beams of the automobile and on the inner side of the front bumper. It is an important component of the automobile bumper. The front cross beam is usually made of hot-formed plates, and the end face of the component is generally straight or arched.

[0003] The existing front cross beam assembly has poor anti-collision performance during use. When a collision occurs, it is easy to deform due to the lack of an anti-collision mechanism, which leads to a short service life. Therefore, a front cross beam assembly is urgently needed to solve the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a front crossbeam assembly.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A front crossbeam assembly includes a crossbeam body with an arched structure, an anti-collision buffer component is installed in the crossbeam body, and the anti-collision buffer component is composed of a multi-layer structure of a leaf spring, a through cavity, a buffer block and a fixing frame. Mounting plates are fixed at both ends of the crossbeam body, and mounting holes are opened at the four corners of the mounting plate.

[0007] Preferably, the crossbeam body is a hollow structure, and the through cavity is formed on the crossbeam body.

[0008] Preferably, the fixing frame is welded in the beam body, the leaf spring is fixed in the fixing frame, and the leaf spring is formed by stacking a plurality of steel plates of unequal lengths and unequal curvatures.

[0009] Preferably, the buffer block is welded to the leaf spring plate, and the buffer block passes through the through cavity.

[0010] Preferably, the mounting plate is welded to both ends of the leaf spring, and the mounting hole is formed on the mounting plate.

[0011] Beneficial technical effects of the utility model:

[0012] The utility model designs an anti-collision buffer mechanism composed of a group of overlapped leaf springs and buffer blocks. When a collision occurs during the use of the front cross beam, the buffer block pre-presses the leaf spring to cause it to undergo elastic deformation, thereby absorbing the force of the collision, thereby effectively protecting the front cross beam, avoiding its deformation, and ensuring its service life and dustproof buffer performance.

[0018] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0019] like Figure 1-Figure 3 As shown, a front crossbeam assembly provided in this embodiment includes a crossbeam body 1 with a bow-shaped structure, an anti-collision buffer component 4 is installed in the crossbeam body 1, and the anti-collision buffer component 4 is composed of a multi-layer structure of a leaf spring 402, a through cavity 404, a buffer block 401 and a fixing frame 403, and mounting plates 2 are fixed at both ends of the crossbeam body 1, and mounting holes 3 are opened at the four corners of the mounting plate 2.

[0020] The interior of the beam body 1 is a hollow structure, and a through cavity 404 is formed on the beam body 1 . The through cavity 404 provides a through space for the buffer block 401 .

[0021] The fixing frame 403 is welded in the beam body 1 , and the leaf spring 402 is fixed in the fixing frame 403 . The leaf spring 402 is formed by stacking a plurality of steel plates of unequal lengths and unequal curvatures. The fixing frame 403 can limit and fix the leaf spring 402 .

[0022] The buffer block 401 is welded on the leaf spring 402, and the buffer block 401 passes through the through cavity 404. During the use of the front cross beam, when an impact occurs, the buffer block 401 pre-presses the leaf spring 402, thereby causing it to undergo elastic deformation, which can absorb the force of the impact, thereby effectively protecting the front cross beam, avoiding its deformation, and ensuring its service life and dust-proof buffering performance.

[0023] The mounting plate 2 is welded to both ends of the leaf spring 402 , and mounting holes 3 are formed on the mounting plate 2 . The mounting holes 3 on the mounting plate 2 are convenient for mounting the crossbeam body 1 .

[0024] The working principle of this device is as follows: the beam body 1 is installed through the mounting hole 3 on the mounting plate 2. During the use of the beam body 1, when an impact occurs, the buffer block 401 is pre-pressed with the leaf spring 402, thereby causing it to undergo elastic deformation, which can absorb the force of the impact, thereby effectively protecting the beam body 1, avoiding its deformation, and ensuring its service life and dustproof and buffering performance.

[0025] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
