Description

Technical Field

[0001] The utility model relates to the technical field of automobile back panels, in particular to an automobile back panel with a noise reduction function. Background Art

[0002] A car back panel is the partition between the vehicle's underbody and the passenger compartment, typically made of materials such as metal, wood, and plastic. Metal, such as steel and aluminum alloy, is one of the most commonly used materials for car back panels. Metal offers strong durability and load-bearing capacity, supporting the vehicle's weight while protecting occupants.

[0003] First, after the car back panel is assembled on the car, the noise reduction function is deviated due to the influence of its own materials. In addition, the car back panel is generally used in conjunction with the tail curtain, but the existing tail curtain is thin, easy to deform, and has poor flatness. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a car back panel with a noise reduction function, which overcomes the deficiencies of the prior art and effectively solves the problems of poor noise reduction function and easy deformation of the tail curtain.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A car back panel with a noise reduction function includes a back panel frame, an inner wall at the bottom of the back panel frame is provided with positioning rings distributed at equal distances, and double-sided adhesive is bonded to the inside of the positioning rings, and foam is bonded to the top outer wall of the double-sided adhesive, a tail curtain is provided on the inner wall at the bottom of the back panel frame, and rivets are welded between the back panel frame and the tail curtain, and a surrounding edge is provided around the top outer wall of the tail curtain.

[0007] Preferably, the outer wall of the top of the surrounding edge is sewn with connecting belts distributed at equal distances.

[0008] Preferably, a card window is provided at one end of the inner wall of the bottom of the back panel frame.

[0009] Preferably, both sides of the outer wall of the bottom of the back panel frame are fixedly connected with side buckles.

[0010] Preferably, positioning seats are fixedly connected to both sides of the outer wall of the bottom of the back panel frame where the foam is added.

[0011] Preferably, the outer wall of the bottom of the back panel frame is fixedly connected with point buckles on both sides of the foam.

[0012] The beneficial effects of the utility model are:

[0013] 1. This design of a car back panel with noise reduction function has a positioning ring and double-sided adhesive set inside the back panel frame to complete the positioning and bonding functions in sequence. It relies on multiple foam fixations to play a buffering role on the one hand, reducing the hard contact of the car back panel, and on the other hand, adding foam as a sound-absorbing material can improve the noise reduction function;

[0014] 2. The car back panel designed in this paper has a noise reduction function. The tail curtain can be welded to the back panel frame by a row of rivets. The tail curtain is thickened to increase the overall hardness and is not easy to deform. The appearance is optimized and the flatness is better, thereby improving the quality of the car back panel.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1, refer to Figure 3 A car back panel with a noise reduction function includes a back panel frame 1. The bottom inner wall of the back panel frame 1 is provided with positioning rings 2 distributed at equal distances, and the inside of the positioning ring 2 is bonded with double-sided adhesive 3, and the top outer wall of the double-sided adhesive 3 is bonded with foam 4.

[0021] In this embodiment, a positioning ring 2 and double-sided adhesive 3 are provided inside the back panel frame 1 to successively complete the functions of positioning and bonding. Relying on the fixation of multiple foams 4, on the one hand, it can play a buffering role and reduce the hard contact of the car back panel. On the other hand, adding foam 4 as a sound-absorbing material can improve the noise reduction function.

[0022] Example 2, refer to Figure 1-2A car back panel with a noise reduction function, a tail curtain 5 is provided on the bottom inner wall of the back panel frame 1, and a rivet 6 is welded between the back panel frame 1 and the tail curtain 5, and a surrounding edge 7 is provided around the top outer wall of the tail curtain 5.

[0023] In this embodiment, the tail curtain 5 can be welded to the back panel frame 1 using a row of rivets 6. The tail curtain 5 is thickened to increase its overall hardness and prevent deformation, thereby optimizing its appearance and improving its flatness, thereby improving the quality of the car's back panel.

[0024] Reference Figure 1 The outer wall of the top of the surrounding edge 7 is sewn with connecting strips 8 distributed at equal distances.

[0025] Reference Figure 1-2 A card window 9 is provided at one end of the inner wall at the bottom of the back panel frame 1 .

[0026] Reference Figure 1 , side buckles 10 are fixedly connected to both sides of the bottom outer wall of the back panel frame 1.

[0027] Reference Figure 1 The outer wall of the bottom of the back frame 1 is located on both sides of the foam 4 and is fixedly connected with a positioning seat 11.

[0028] Reference Figure 1 The outer wall of the bottom of the back frame 1 is located on both sides of the foam 4 and is fixedly connected with point buckles 12.

[0029] Working principle: A positioning ring 2 and double-sided adhesive 3 are set inside the back panel frame 1, and the foam 4 can be bonded to the double-sided adhesive 3. The noise reduction function is improved by relying on multiple foams 4. At the same time, a row of rivets 6 can be used to weld the tail curtain 5 to the back panel frame 1. The tail curtain 5 is thickened to increase the overall hardness and is not easy to deform. When the back panel frame 1 is assembled to the vehicle, the side buckles 10, point buckles 12 and positioning seats 11 inside the back panel frame 1 can complete the snap connection, reducing the difficulty of assembly.
