[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] Embodiment 1

[0033] This embodiment relates to a dust-proof structure under a vehicle door, which can improve the problem that dust easily enters the gap 5 between the bottom of the vehicle door 1 and the side panel 2; an exemplary structure thereof is as follows Figure 1 , Figure 2 and Figure 3 shown.

[0034] In general, the door lower dustproof structure includes a dustproof strip 4 provided between the bottom of the door inner panel 11 and the side panel decorative panel 2 outside the door sill. The dustproof strip 4 includes a mounting seat 41 fixed on the door inner panel 11, and a main body 42 whose root 420 is connected to the top of the mounting seat 41; wherein the main body 42 is bent and extended downward relative to the mounting seat 41, and the end 421 of the main body 42 is inclined toward the side panel decorative panel 2, and abuts against the position of the side panel decorative panel 2 corresponding to the lower edge of the door 1.

[0035] Specifically, if Figure 2 and Figure 3 As shown, the mounting seat 41 of this embodiment is fixed on the door inner panel 11 by means of a buckle 40. The dust strip 4 is mounted on the door inner panel 11 by means of the buckle 40, which is not only convenient for installation, but also the mounting structure is hidden inside the door 1 and below the dust strip 4, so that the mounting structure is not exposed, thereby maintaining the neatness of the sealing structure at the bottom of the door 1.

[0036] Preferably, the mounting seat 41 is made of PP material, the main body 42 is made of EPDM material, and the main body 42 is injected onto the mounting seat 41 by an integrated injection molding process. The mounting seat 41 is made of a harder PP (polypropylene) material, which has good installation stability, and the main body 42 is made of EPDM (Ethylene Propylene Diene Monomer), which has good elasticity, excellent aging resistance, and good sealing and dustproof effect. Considering that the material used for the main body 42 is relatively soft, while the material of the mounting seat 41 and the buckle 40 thereon is relatively hard; when the door 1 is closed, in order to prevent the main body 42 bent on one side of the buckle 40 from touching and wearing the head of the buckle 40, thereby affecting the durability of the main body 42; preferably, by reasonably setting the bending angle and posture of the main body 42, when the door 1 is closed, there is a certain gap between the main body 42 and the buckle 40; the size and reasonable setting of the gap can be set to 1mm to 4mm, for example.

[0037] In order to improve the aesthetics of the side panel decorative plate 2, a decorative strip 21 is provided on the side panel decorative plate 2 of this embodiment; Figure 1 As shown, the decorative strip 21 is embedded in the middle of the outer side of the side decorative panel 2 along the length direction of the side decorative panel 2 .

[0038] like Figure 3 As shown, in order to improve the sealing performance of the dust strip 4, it is preferred to set a certain amount of interference between the main body 42 and the door inner panel 11, and between the main body 42 and the side decorative panel 2. In this embodiment, the first interference amount b between the root 420 and the surface of the door inner panel 11 is greater than 0.5 mm. When the door 1 is closed, the second interference amount t between the end 421 and the surface of the side decorative panel 2 is greater than 3 mm. By setting a reasonable amount of interference between the root 420 of the main body 42 and the door inner panel 11, and between the end 421 and the side decorative panel 2, the elastic deformation of the main body 42 can be used to form a good sealing effect between the door inner panel 11 and the side decorative panel 2, thereby ensuring the sealing and dustproof performance of the dust strip 4.

[0039] In addition, when the door is closed, an angle a is formed downward between the end 421 of the main body 42 abutting against the side panel 2 and the surface of the side panel 2. Preferably, the angle a is set to be greater than 150°. A reasonable angle is set between the end 421 of the main body 42 and the side panel 2 to ensure that the main body 42 is elastically deformed smoothly under the pressure of the side panel 2 and the elastic deformation of the main body 42 is kept within a reasonable range, which is beneficial to the durability of the dust strip 4.

[0040] In addition, the door lower dustproof structure of this embodiment further includes a door sealing strip 12 provided on the door inner panel 11, and the door sealing strip 12 is located above the dustproof strip 4. When the door 1 is closed, the door sealing strip 12 is clamped between the door inner panel 11 and the side panel metal 3 at the door sill. By providing the door sealing strip 12 above the dustproof strip 4, the dustproof strip 4 and the door sealing strip 12 cooperate with each other to form two seals, which can isolate external water stains, dust, noise, etc. from entering the cockpit, thereby improving the quiet effect in the car during driving, improving the sound insulation performance of the vehicle, and forming a good touch feeling between the door 1 and the door frame when the door 1 is closed, thereby improving the customer perception effect.

[0041] In addition to achieving sealing by abutting the end 421 of the main body 42 against the surface of the side decorative panel 2, some sealing lips may be added to the main body 42. In this embodiment, a sealing lip 422 is provided on the side of the main body 42 facing the vehicle door 1; the sealing lip 422 is arranged near the end 421 and abuts against the bottom edge of the vehicle door 1. The sealing lip 422 is arranged near the end 421 of the main body 42, and the sealing lip 422 abuts against the bottom edge of the vehicle door 1. The sealing lip 422 cooperates with the end 421 to seal the gap 5 between the vehicle door 1 and the side decorative panel 2 tightly, preventing dust from entering the cavity between the main body 42 and the door inner panel 11.

[0042] Based on the above-mentioned setting, a buffer pad 43 is provided at the bottom edge of the vehicle door 1 of this embodiment, and the sealing lip 422 is abutted and connected with the buffer pad 43. The structure of the vehicle door 1 generally includes a vehicle door outer panel 10 and a vehicle door inner panel 11. At the bottom edge of the vehicle door 1, the vehicle door outer panel 10 is bent to form a rim 100 that wraps the edge of the vehicle door inner panel 11; therefore, the above-mentioned buffer pad 43 can be bonded and fixed to the rim 100. The buffer pad 43 is provided at the corresponding position of the sealing lip 422 to improve the sealing matching effect between the sealing lip 422 and the bottom edge of the vehicle door 1. The buffer pad 43 can be a foam cushion or a rubber cushion, and the sealing lip 422 can also be bonded and fixed to the buffer pad 43, thereby improving the installation stability of the dust strip 4.

[0043] To sum up, the dust-proof structure under the vehicle door of the present embodiment is achieved by arranging a dust-proof strip 4 between the bottom of the vehicle door inner panel 11 and the side decorative panel 2. By utilizing the bending structure between the main body 42 and the mounting seat 41, the end 421 of the main body 42 can be elastically abutted against the surface of the side decorative panel 2, thereby forming a blockage for the gap 5 between the bottom edge of the vehicle door 1 and the side decorative panel 2, and preventing external dust from entering the interior through the gap 5, thereby improving the problem of dust easily entering the gap 5 between the bottom of the vehicle door 1 and the side decorative panel 2; in this way, the problem of dust accumulating on the threshold step formed by the top 20 of the side decorative panel 2 and easily dirtying the clothes of people entering and leaving the cab can be avoided.

[0044] Embodiment 2

[0045] This embodiment relates to a vehicle, the vehicle door 1 of which adopts the lower door dust-proof structure provided in the first embodiment.

[0046] In view of the situation where a side decorative panel 2 is provided under the vehicle door 1, a dust strip 4 is provided on the door inner panel 11 to effectively prevent dust from entering the gap 5 and falling onto the step 20 of the top of the side decorative panel 2, while also having good waterproof and sound insulation effects.

[0047] In addition, due to the double-layer sealing and buffering effect of the dust strip 4 and the door sealing strip 12, the airflow entering the vehicle can be reduced during high-speed driving of the vehicle, thereby improving the clarity of the voice inside the vehicle and also producing a good effect on improving the quality of the closing sound when the door 1 is closed.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
