Description

Technical Field

[0001] The invention belongs to the technical field of automobile side door sealing, and in particular relates to an automobile side door sealing structure. Background Art

[0002] The side of the car, especially the area in front of the rear wheel, has a complex matching structure, involving a combination of structures such as the side door, sealing strips, and side panels. At the same time, the external environment at this location is harsh, and mud and snow will be thrown during the movement of the car, and it is easy to freeze in extremely cold weather. Therefore, the matching seal at this location is particularly critical. It is necessary to ensure that no mud or dust can be thrown into the cabin during the movement of the car. At the same time, it is necessary to ensure that the accumulation of mud and sand in this area during long periods of rain and snow will not cause paint wear or paint loss when the door is opened.

[0003] However, the traditional side structure of a car is generally equipped with a sealing bubble tube on the side door or side door trim, and the sealing bubble tube is matched with the side panel metal gap. Therefore, when the car is moving, the area in front of the rear wheel is prone to poor sealing, and dust and mud and sand enter. When encountering rainy, snowy and freezing weather, this position will freeze. During movement, the mud and sand attached to the bubble tube will splash onto the side panel paint surface, which may easily cause paint wear problems. If the car door has not been opened for a long time, suddenly opening the door may easily cause local paint loss, thereby accelerating the corrosion of the sheet metal here and affecting the service life of the car body. Summary of the Invention

[0004] In response to the above problems, the present invention proposes a side sealing structure for an automobile, comprising: a side door portion, a side panel portion, a sealing portion and a mounting portion made of plastic material. The sealing portion is provided on one side of the edge of the side door portion, and the mounting portion is detachably provided along the frame of the side panel portion. When the vehicle door is closed, the side door portion abuts against the side panel portion, so that the sealing portion is tightly attached to the mounting portion.

[0005] Optionally, the sealing portion includes a sealing fixed end and an elastic sealing member. When the vehicle door is opened, the top end of the elastic sealing member abuts against the mounting portion. When the vehicle door is closed, the elastic sealing member is attached to the mounting portion. The sealing fixed end is sealed on one side of the edge of the side door portion, and the elastic sealing member is arranged on the sealing fixed end.

[0006] Optionally, the outer shape structure of the elastic seal is a U-shaped structure or an O-shaped structure.

[0007] Optionally, the top thickness of the elastic seal is 2 mm to 4 mm.

[0008] Optionally, a circle of sponge rubber is provided between the sealing fixing end and the side door portion.

[0009] Optionally, the mounting portion includes a connecting end and a sealing end, the connecting end is fixedly connected to the side surrounding portion, a portion of the sealing end is sealed on the side surrounding portion, and the other portion is opposite to the sealing portion, and when the vehicle door is closed, the sealing portion is attached to the sealing end, the connecting end and the sealing end are connected, and the connecting end and the sealing portion are respectively located on both sides of the sealing end.

[0010] Optionally, the sealing end is provided with a groove structure, and the connecting end is provided in the groove structure.

[0011] Optionally, foam is filled between the sealing end and the side surrounding portion.

[0012] Optionally, the mounting portion further includes a snap-fit structure, one end of the snap-fit structure is connected to the connecting end and the other end of the sealing fixed end is snapped into a slot provided on the side surrounding portion.

[0013] Optionally, the sealing portion further includes a snap-fit structure, and the sealing fixing end is arranged on one side of the edge of the side door portion through the snap-fit structure.

[0014] The automobile side sealing structure provided by the present invention has the following advantages compared with the prior art: By providing a sealing portion on one side of the edge of the side door and a removable mounting portion along the frame of the side panel, the sealing portion tightly adheres to the mounting portion when the door is closed, thus achieving an interference seal. This avoids the problem of insufficient sealing caused by gap sealing in the existing technology, ensuring a high seal between the side door and the side panel, and preventing mud, sand, and dust from entering the cabin. In addition, the mounting portion is also sealed to ensure the sealing of the side panel cavity. The mounting portion is made of plastic and has an interference fit with the sealing portion. Even in the event of mud or freezing weather, paint will not peel when the door is opened, thus avoiding sheet metal corrosion in this area and extending the service life of the vehicle body.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0020] like Figure 1 and Figure 2As shown, the present invention provides a side sealing structure for an automobile, comprising: a side door portion 1, a side panel portion 2, a sealing portion 3, and a mounting portion 4 made of plastic. The sealing portion 3 is provided on one side of the edge of the side door portion 1, and the mounting portion 4 is detachably provided along the frame of the side panel portion 2. When the vehicle door is closed, the side door portion 1 abuts against the side panel portion 2, so that the sealing portion 3 is tightly attached to the mounting portion 4 to seal the gap between the side door portion 1 and the side panel portion 2. The cooperation between the sealing portion 3 and the mounting portion 4 made of plastic not only satisfies the high sealing performance between the side door and the side panel, but also prevents mud, sand, and dust from entering the cabin. At the same time, due to the plastic mounting portion 4 and the sealing portion 3, even if mud and sand adhere to the gap between the sealing portion 3 and the mounting portion 4 during movement, if the vehicle door has not been opened for a long time, the problem of partial paint peeling will not occur when the door is suddenly opened. This avoids corrosion of the sheet metal at this position and improves the service life of the vehicle body. It should be noted that the present invention uses the sealing portion 3 to seal the entire mounting portion 4 when the door is closed. Compared with the prior art, even when the door is closed, a large gap exists between the large component structure and the side panel 2. The existing sealing method relies solely on the protruding portion of the sealing portion 3 to cover the edge of the side panel 2. Compared with the sealing method of the present invention, the sealing method of the present invention greatly improves the sealing performance.

[0021] like Figure 1 As shown, optionally, the structure also includes a rear door decorative panel 5, a rear wheel cover guard plate 7 and a rear wheel eyebrow decorative panel 6. The rear door decorative panel 5 is connected to the side door portion 1, and the rear wheel eyebrow decorative panel 6 is connected to the side portion 2, thereby forming an overall arc-shaped structure along the direction of the wheel, making the vehicle look beautiful and tidy. One end of the rear wheel cover guard plate 7 is provided on the vehicle, and the other end surrounds half the circumference of the wheel and is close to the rear door decorative panel 5 and the rear wheel eyebrow decorative panel 6, protecting the large sheet metal surface in the wheel cover area from mud, sand and rain.

[0022] like Figure 3As shown, in one embodiment, the sealing portion 3 includes a sealing fixed end 31 and an elastic seal 32. When the vehicle door is open, the top end of the elastic seal 32 abuts against the mounting portion 4. When the vehicle door is closed, the elastic seal 32 is attached to the mounting portion 4. The sealing fixed end 31 is sealed on one side of the edge of the side door portion 1, and the elastic seal 32 is disposed on the sealing fixed end 31. This ensures that the elastic seal 32 on the sealing fixed end 31 is fixed and stable. The elastic seal 32 can also be disposed in a predetermined position, i.e., the elastic seal 32 is located at the sealing opening. Optionally, a fixing hole is provided in the side door portion 1. The diameter of the hole can be 5 mm. The diameter of the fixing hole can also be designed according to design requirements to facilitate cooperation with a snap-fit structure. The snap-fit structure is inserted through the sealing fixed end 31 and is snap-fitted or riveted to the fixing hole. This allows the sealing fixed end 31 to be firmly fixed to the side door portion 1, and the elastic seal 32 will not change position, thereby avoiding affecting the seal. It should be noted that when the vehicle door is not closed, the top end of the elastic seal 32 is close to or can abut against the mounting portion 4. When the vehicle door is closed, the top end of the elastic seal 32 is also pressed onto the mounting portion 4 and sealed along the entire mounting surface, thereby improving the sealing effect.

[0023] In one embodiment, the outer shape of the elastic seal 32 is approximately a square or O-shaped structure. Optionally, the outer shape of the elastic seal 32 can also be a rectangular structure, a trapezoidal structure, a Q-shaped structure, a D-shaped structure, or other shapes that match the mounting portion 4. The elastic seals 32 of these different structural shapes are easier to press against the sealing end 42 in the mounting portion 4, and the elastic seals 32 of these structural shapes can fill the sealing area. The sealing surface of the sealing area is large enough to ensure sufficient sealing at the sealing area, thereby improving the sealing effect. Optionally, the elastic seal 32 can be a sealing structure made of rubber.

[0024] In one embodiment, the top thickness of the elastic seal 32 is 2-4 mm. Specifically, the top thickness of the elastic seal 32 is 2, 3, or 4 mm. Compared to existing thicknesses, the top thickness of the elastic seal 32 of the present invention is significantly greater than that of existing ones. A sufficiently thick top of the elastic seal 32 allows the elastic seal 32 to achieve a better sealing effect when it seals with one side of the mounting portion 4. Optionally, the elastic seal 32 can be a sealed bubble tube. In addition, a sealing section is provided on the periphery of the elastic seal 32. The sealing section on the elastic seal 32 is formed continuously along one side of the elastic seal 32. A stopper can be formed on the side adjacent to the elastic seal 32. When the elastic seal 32 is tightly attached to the mounting portion 4, the sealing section can abut against one side of the mounting portion 4, i.e., one side of the sealing end 42. Alternatively, the stopper can cooperate with a corner of the mounting portion 4 (sealing end 42) to achieve sealing, further improving the sealing performance.

[0025] In one embodiment, a ring of sponge rubber 33 is provided between the sealing fixing end 31 and the side door portion 1. It should be noted that the sponge rubber 33 and the elastic sealing member 32 are formed into an integral sealed bubble tube structure through an extrusion vulcanization and cross-linking process. The sponge rubber 33 prevents some mud, sand, other dust, rain, and snow from entering through the sealing portion 3, further improving the sealing performance.

[0026] In one embodiment, the mounting portion 4 includes a connecting end 41 and a sealing end 42. The connecting end 41 is fixedly connected to the side panel 2. A portion of the sealing end 42 is sealed against the side panel 2, while the other portion faces the sealing portion 3. When the vehicle door is closed, the sealing portion 3 is positioned above the sealing end 42. The connecting end 41 and the sealing end 42 are connected, and the connecting end 41 and the sealing portion 3 are located on either side of the sealing end 42. It should be noted that since the sealing end 42 is detachably connected to the side panel 2, a fixing groove is provided on the side panel 2, and a protrusion is provided on the sealing end 42 to engage with the fixing groove. The protrusion engages with the fixing groove, allowing the sealing end 42 to be removed and accessed at any time when parts need to be replaced, thereby improving convenience. Furthermore, the sealing end 42 is made of plastic. If the vehicle door has not been opened for a long time, there may be some dirt or ice between the sealing end 42 and the sealing portion 3. However, when the door is opened, strong adhesion between metal and metal or paint peeling will not occur. In addition, the outer shape of the sealing end 42 can be an arch-shaped structure or a bench-shaped structure. This structure is convenient for fixed connection with the side surrounding portion 2 on the one hand, and is convenient for sealing cooperation with the elastic sealing component 32 on the other hand.

[0027] In one embodiment, the sealing end 42 is provided with a groove structure, and the connecting end 41 is disposed within the groove structure. The groove structure facilitates mating with the side panel 2, and also facilitates mating with the sealing portion 3, and facilitates securing the connecting end 41. Furthermore, the groove structure can block some mud, dust, rain, snow, etc.

[0028] In one embodiment, foam 43 is filled between the sealing end 42 and the side surrounding portion 2. The foam 43 structure effectively prevents airflow and dust from entering the cabin through the gap, thereby improving the sealing performance.

[0029] In one embodiment, the mounting portion 4 further includes a snap-fit structure 44, one end of which is connected to the connecting end 41 and the other end of which snaps into a slot provided on the side panel 2. Alternatively, the snap-fit structure 44 can be a buckle, and the engagement of the buckle with the slot securely secures the sealing end 42 to the side panel 2. Furthermore, the connection between the snap-fit structure 44 and the connecting end 41 forms a partial barrier within the groove structure of the sealing end 42, effectively preventing airflow and dust from entering the sheet metal cavity. Optionally, the connecting end 41 is composed of two connecting plates, both of which can be L-shaped structures and are arranged at intervals. Two grooves are respectively provided on both sides of one end of the clamping structure 44, and the two connecting plates can respectively cooperate with the two grooves. The other end of the clamping structure 44 is provided with two grooves along the axial direction of the middle area. Due to the presence of the two grooves, it is convenient to press the two sides of the clamping structure 44 to reduce the radial dimensions of the two grooves, and the width of the entire clamping structure 44 is reduced, so that when the clamping structure 44 enters the corresponding clamping slot, the clamping structure 44 can be squeezed, so that the width of the clamping structure 44 becomes smaller. When it completely enters the clamping slot, the width of the clamping structure 44 is restored under its own structural restoring force, thereby achieving tight clamping.

[0030] like Figure 4 As shown, in one embodiment, the sealing portion 3 further includes a snap-fit structure 34, which positions the sealing fixed end 31 on one side of the edge of the side door portion 1. Optionally, the snap-fit structure 34 can be a buckle, which passes through the sealing fixed end 31 on the sealing portion 3 and cooperates with a slot on the side door portion 1 to fix the sealing portion 3. In addition, one end of the snap-fit structure 34 can have an arrow-shaped shape, and the other end can have a T-shaped shape. The outer shape of the snap-fit structure 34 can cooperate with the corresponding sealing fixed end 31 and slot, that is, the side door portion 1 and the sealing fixed end 31 are provided with structures that cooperate with the snap-fit structure 34. It should be noted that these mutually cooperating structures are riveted structures.

[0031] Optionally, a door frame sealing strip 8 is provided between the side door portion 1 and the side enclosure portion 2 to further enhance the sealing performance. In addition, a wheel house outer panel and a wheel house inner panel are provided on the side enclosure portion 2 to further block the entry of dust, mud, sand, rain, snow and ice.

[0032] In summary, by providing a sealing portion 3 on one side of the edge of the side door portion 1 and a detachable mounting portion 4 along the frame of the side panel portion 2, when the door is closed, the sealing portion 3 is tightly attached to the mounting portion 4, thereby achieving an interference seal, avoiding the problem of insufficient sealing caused by gap sealing in the prior art, ensuring high sealing between the side door and the side panel, and effectively preventing airflow, dust, and mud from entering the cabin during the movement of the car. In addition, the mounting portion 4 is also sealed to meet the sealing of the side panel cavity. The mounting portion 4 is a plastic structure and cooperates with the sealing portion 3 to seal. Even if there is some mud or extremely bad weather such as rain, snow, and ice, there will be no paint grinding or peeling problems in this area, thereby avoiding sheet metal corrosion in this position and improving the service life of the car body.
