[0023] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a front left door panel structure of a car, comprising an outer door panel 1, wherein the inner outer wall of the outer door panel 1 is fixedly connected with a plurality of fixing rods 11, both ends of the outer wall of the fixing rods 11 are fixedly connected with a fixing plate 10, the inner outer wall of the outer door panel 1 is fixedly connected with a plurality of first connecting plates 12, one end surface of the first connecting plate 12 is fixedly connected with a retractable rod 14, one end surface of the retractable rod 14 is fixedly connected to one end surface of the fixing plate 10, a first spring 13 is sleeved on the outer wall of the retractable rod 14, a plurality of sliders 17 are slidably connected to the middle part of the outer wall of the fixing rod 11, a second spring 18 is arranged on one end surface of the two sliders 17, one end surface of the slider 17 away from the second spring 18 is rotatably connected to the second connecting plate 16, one end surface of the second connecting plate 16 is rotatably connected to the rotating plate 15, and the bottom end surface of the rotating plate 15 is fixedly connected to the inner side wall of the outer door panel 1.

[0025] Specifically, when the middle part of the outer door panel 1 of the front left door of the automobile is squeezed, the outer door panel 1 is squeezed and deformed, causing the second connecting plate 16 to move inward. Since the rotating plate 15 is rotatably connected to the surface of one end of the slider 17, the two sliders 17 can slide on the fixed rod 11, thereby squeezing the second spring 18. By utilizing the rebound ability of the second spring 18, the slider 17 can be reset, so that the second connecting plate 16 can be restored to its original position, and the deformed part in the middle part of the outer door panel 1 can be restored. When the two sides of the outer door panel 1 are squeezed and deformed, the rebound of the first spring 13 can be utilized to make the retraction rod 14 re-support the two sides of the outer door panel 1, thereby restoring the appearance of the outer door panel 1. This arrangement can enable the outer door panel 1 of the front left door of the automobile to quickly restore its original shape after deformation.

[0026] Reference Figure 2 and Figure 5 The inner side wall of the outer door panel 1 is fixedly connected to the inner door panel 6, and the inner door panel 6 comprises a surface layer 20, a fireproof layer 21, a sound absorbing layer 22, a shock absorbing layer 23 and a base material layer 24 from the outside to the inside.

[0027] Specifically, the surface layer 20 of the inner door panel 6 uses waterproof synthetic leather. The waterproof synthetic leather has a certain waterproof performance and can resist the penetration of water to a certain extent, so that it can protect the wiring harness in the left front door in a humid environment and prevent it from being affected. The fireproof layer 21 can use flame-retardant synthetic materials, etc., which can slow down the spread of fire in the event of a fire and protect the safety of passengers in the car. The sound-absorbing layer 22 can use sound-absorbing cotton, which can absorb noise and vibration, reduce the noise level in the car, and improve the riding experience. The shock-absorbing layer 23 uses shock-absorbing foam, which can reduce the bumpy feeling when the vehicle is driving and improve ride comfort. The base material layer 24 can use carbon fiber material. Carbon fiber has very high strength and rigidity, and is light in weight. The use of carbon fiber material can reduce the weight of the inner door panel 6.

[0028] Reference Figure 1 and Figure 2 The upper end surface of the outer door panel 1 is fixedly connected to a glass frame skeleton 2, and a double-layer soundproof glass 3 is arranged inside the glass frame skeleton 2.

[0029] Specifically, the double-layer soundproof glass 3 isolates the sound inside the vehicle from the external sound, thereby improving the comfort of the passengers inside the vehicle.

[0030] Reference Figure 1 and Figure 2 A handle 5 is provided on one end surface of the outer door panel 1, and an internal wrench 7 is provided on one end surface of the inner door panel 6.

[0031] Reference Figure 1 The side end surface of the outer door panel 1 is fixedly connected to two connecting plates 4.

[0032] Specifically, the connecting plate 4 facilitates the connection of the left front door to the vehicle frame.

[0033] Reference Figure 2 A sound system 9 is arranged at the lower right part of the inner door panel 6 , and a storage box 8 is arranged at the middle part of the inner door panel 6 .

[0034] Specifically, the storage box 8 can be used to store personal items such as water cups, mobile phones, etc.

[0035] Reference Figure 4 The outer wall of the fixing rod 11 near the sliding block 17 is fixedly connected to the limiting plate 19 .

[0036] Specifically, the limiting plate 19 can prevent the second spring 18 from excessively rebounding.

[0037] Reference Figure 2 and Figure 3 , the fixing plate 10 is arranged behind the inner door panel 6.

[0038] Specifically, this arrangement facilitates the arrangement of other components inside the inner door panel 6, such as reinforcing ribs and a glass lifting component.

[0039] Working principle: When both sides of the outer door panel 1 of the left front door panel of the car are squeezed by external force, the first spring 13 can be used to restore the first connecting plate 12 to its original position by the rebound ability of the first spring 13, so that the deformed part can be restored to its original shape. When the middle part of the outer door panel 1 is squeezed and deformed, the second spring 18 can be used to restore the slider 17 to its original position by the rebound elasticity, and then the second connecting plate 16 can be used to drive the deformed part to restore its original shape through the rotating plate 15; the inner door panel 6 is composed of a surface layer 20, a fireproof layer 21, a sound-absorbing layer 22, a shock-absorbing layer 23 and a base material layer 24 from the outside to the inside, which can improve the comfort and safety of the users, thereby improving the competitiveness of the car.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
