Description

Technical Field

[0001] This invention relates to a sealing structure and sealing element for automobiles, which are used to seal the gap between the door and the wheel arch, which is disposed opposite to the upper surface of the tire, when the door is closed. Background Technology

[0002] In the past, such as Figure 5 and Figure 6 As shown, there is a known structure that seals the gap between a car door (rear door) 1 and a wheel arch 3 that is disposed opposite to the upper surface of the tire 2.

[0003] This structure is used to elastically contact the protrusion 11 of the guard plate 10 installed on the door 1 with the sealing hollow portion 22 of the seal 20 when the door 1 is closed, thereby blocking the gap between the door 1 and the wheel arch 3. The U-shaped mounting portion 21 in the seal 20 is installed on the outer periphery of the wheel arch 3 (for example, see Patent Document 1). Figure 3 ).

[0004] Based on the above structure, mud, small stones, etc. can be prevented from entering the interior of the vehicle through the gap between the door 1 and the wheel arch 3.

[0007] Patent document 1: Japanese Patent Application Publication No. 2014-180921. Summary of the Invention

[0008] Problems to be solved by the invention

[0009] However, in Figure 6 In the sealing structure shown, when the door 1 is closed, the protruding part 11 of the guard plate 10 makes elastic contact with the central part of the sealing hollow part 22 of the seal 20 to seal. Therefore, mud and the like will adhere to the area X which is lower than the elastic contact position.

[0010] Therefore, there is a problem that when occupants enter the car with the door open, their clothes come into contact with the surface of the lower part of the seal 20 and get dirty.

[0011] Furthermore, since the mounting portion 21 of the seal 20 is inserted into the flange 3a of the outer periphery of the wheel arch portion 3, there is also a problem that mud and dust can enter the mounting portion 21, which has a roughly U-shaped cross-section.

[0012] Furthermore, the protective plate 10 is made of resin, which has lower rigidity than the door 1 made of metal and is more prone to deformation. If the deformation of the protective plate 10 increases, it will result in a deterioration of the vehicle's appearance and compromise the stability of the sealing function. Therefore, the design of the elastic contact between the protrusion 11 of the protective plate 10 and the sealing hollow portion 22 of the seal 20 needs to maintain a low compressive load.

[0013] Therefore, the object of the present invention is to provide a sealing structure and sealing components for automobiles that prevent clothing from getting dirty while riding in a vehicle.

[0014] In addition, the present invention aims to provide a sealing structure for automobiles that minimizes the deformation of the skid plate.

[0015] In addition, the present invention aims to provide a sealing structure and sealing element for automobiles that achieve a stable sealing function.

[0016] Solutions to the Problem

[0017] To achieve the above objectives, the sealing structure of the automobile of the present invention is such that the guard plate (30) installed on the door (1) of the automobile makes elastic contact with the sealing hollow portion (42) of the sealing member (40) installed near the outer periphery of the wheel arch (5), thereby blocking the gap between the door (1) and the wheel arch (5), wherein the wheel arch (5) is disposed opposite to the door (1) and located above the upper surface of the tire (2), and the sealing structure of the automobile is characterized in that...

[0018] The seal (40) has: a mounting base (41) mounted on the outer side of a vertical plate (6) of the vehicle body that is erected upward from the outer periphery of the wheel arch (5); and a sealing hollow portion (42) disposed at the lower part of the mounting base (41).

[0019] The sealed hollow portion (42) is surrounded by an inner sidewall (43) extending downwardly from the lower part of the mounting base (41) towards the outer side of the vehicle, an outer sidewall (44) connected to the lower end of the inner sidewall (43) and extending upwardly, and a connecting wall (45) extending horizontally from the upper end of the inner sidewall (43) towards the outer side of the vehicle and connected to the outer sidewall (44).

[0020] The guard plate (30) is installed on the inner periphery of the door (1) and has an inclined plate portion (33) extending obliquely downward on the inner side of the vehicle to a position between the wheel arch portion (5) and the upper surface of the tire (2). When the door (1) is closed, the upper side of the inclined plate portion (33) elastically contacts the lower part of the connection portion (47) between the inner sidewall (43) and the outer sidewall (44) of the seal (40).

[0021] The connecting part (47) has a generally tongue-shaped cross-section that extends in a lip-like manner with its thickness gradually decreasing from top to bottom in the inward and outward directions.

[0022] In addition, the present invention is characterized in that a sealing lip (48) that elastically contacts the vertical plate (6) is provided on the upper part of the inner sidewall (43).

[0023] In addition, the present invention is characterized in that a concave portion (49) is formed on the inner side of the inner sidewall (43).

[0024] Furthermore, the present invention is a sealing component for a car that seals the gap between a car door (1) and a wheel arch (5), wherein the wheel arch (5) is disposed opposite to the car door (1) and located above the upper surface of the tire (2), and the sealing component for the car is characterized by having:

[0025] A mounting base (41) is mounted on the outer side of a vertical plate (6) of the vehicle body that is erected from the outer periphery of the wheel arch (5) upwards; and a sealed hollow portion (42) is provided at the lower part of the mounting base (41).

[0026] The sealed hollow portion (42) is surrounded by an inner sidewall (43) extending downwardly from the lower part of the mounting base (41) towards the outer side of the vehicle, an outer sidewall (44) connected to the lower end of the inner sidewall (43) and extending upwardly, and a connecting wall (45) extending horizontally from the upper end of the inner sidewall (43) towards the outer side of the vehicle and connected to the outer sidewall (44).

[0027] The connection (47) between the inner sidewall (43) and the outer sidewall (44) of the vehicle has a generally tongue-shaped cross-section that extends in a lip-like manner with the thickness gradually decreasing from top to bottom in the direction of the vehicle's interior and exterior.

[0028] It should be noted that the markings in parentheses indicate the corresponding elements or matters described in the drawings and the manner of implementing the invention described below.

[0029] Invention Effects

[0030] According to the sealing structure of the automobile of the present invention, the upper side of the inclined plate portion of the door panel is elastically in contact with the lower part of the connection between the inner side wall and the outer side wall of the vehicle, thereby preventing mud and the like from adhering to the lower part of the outer side of the vehicle. The inner side wall and the outer side wall of the vehicle constitute the sealing hollow portion of the seal installed on the outer peripheral side of the wheel arch.

[0031] Therefore, when passengers enter the vehicle, there is almost no risk of their clothes getting dirty, even if they wear trousers or skirts and other clothing come into contact with the sealed exterior surfaces of the vehicle.

[0032] In addition, the appearance will not be affected by the presence of stains on the side of the car body (seales) when the door is opened.

[0033] Furthermore, according to the present invention, the connecting portion is lip-shaped extending from top to bottom, has a generally tongue-shaped cross-section, and this portion elastically contacts the inclined plate portion of the guard plate. Therefore, it is possible to prevent excessive increase in the compressive load on the seal. Additionally, it is also possible to prevent deterioration of the appearance due to excessive deformation of the inclined plate portion of the guard plate during elastic contact. As a result, the sealing function of the seal is also stabilized.

[0034] Furthermore, according to the present invention, the thickness of the connecting portion gradually decreases from top to bottom in the direction between the inside and outside of the vehicle, thereby further preventing the increase of the compressive load on the seal or excessive deformation of the inclined plate portion of the guard plate during elastic contact.

[0035] Furthermore, according to the present invention, a sealing lip is provided on the upper part of the inner sidewall of the vehicle, which elastically contacts a vertical plate of the vehicle body that is erected upward from the outer periphery of the wheel arch on which the seal is mounted. Therefore, mud and the like from the tire can be prevented from entering upward from between the mounting base of the seal and the vertical plate.

[0036] Furthermore, according to the present invention, a concave shape is formed on the inner side of the inner sidewall of the vehicle, thereby preventing the door closure performance from deteriorating by reducing the load on the sealed hollow portion.

[0037] Furthermore, in the automobile seal according to the present invention, the inner side of the door elastically contacts the lower part of the connection between the inner sidewall and the outer sidewall, thereby preventing mud and the like from adhering to the outer side of the lower part of the connection. The inner sidewall and the outer sidewall constitute the sealing hollow part of the seal installed on the outer peripheral side of the wheel arch.

[0038] Therefore, when occupants enter the vehicle, there is virtually no risk of their clothes getting dirty, even if they come into contact with the sealed exterior surfaces of the vehicle.

[0039] In addition, the appearance will not be affected by the presence of stains on the side of the car body (seales) when the door is opened.

[0040] Furthermore, according to the present invention, the connecting portion is lip-shaped extending from top to bottom, has a generally tongue-shaped cross-section, and this portion elastically contacts the inner side of the vehicle door, thus preventing excessive increase in the compressive load on the seal. Consequently, the sealing function of the seal is also stabilized.

[0041] In addition, the thickness of the connection gradually decreases from top to bottom in the direction between the inside and outside of the vehicle, thus preventing an increase in the compressive load on the seal. Attached Figure Description

[0047] Figure 6 This refers to the state of a car door when its sealing structure is closed, as is typical of cars. Figure 5 Enlarged cross-sectional view of line AA. Detailed Implementation

[0048] Reference Figures 1 to 3 as well as Figure 5 The sealing structure of an automobile according to an embodiment of the present invention will be described. Figure 1 This shows the state of the car door (rear door) 1 when it is open. Figure 3 This shows the state of door 1 when it is closed. The same reference numerals are used for parts that are the same as in previous examples.

[0049] The sealing structure of the car is designed to allow the protective panel 30 installed on the car door 1 to elastically contact the sealing hollow portion 42 of the sealing member 40 of the vertical plate 6 installed near the outer periphery of the wheel arch 5, thereby blocking the gap between the car door 1 and the wheel arch 5, which is disposed opposite to the car door 1 and located above the upper surface of the tire 2.

[0050] like Figure 1 As shown, the seal 40 has: a mounting base 41, which is mounted to the outer side of a vertical plate 6 of the vehicle body that is erected upward from the outer periphery of the wheel arch 5 by means of a clamp K; and a sealing hollow portion 42, which is provided at the lower part of the mounting base 41. Figure 2As shown, the seal 40 extends along the wheel arch 5 in an arched shape, is spaced apart from the vertical plate 6, and is fixed to the vertical plate 6 by a clamp K. It should be noted that double-sided tape (not shown) can also be used to fix the seal 40 to the vertical plate 6 instead of the clamp K.

[0051] The sealing hollow portion 42 of the seal 40 is generally triangular in shape, formed by an inner sidewall 43 extending downward from the lower part of the mounting base 41 toward the outer side of the vehicle, an outer sidewall 44 extending upward from the lower end of the inner sidewall 43, and a lower connecting wall (connecting wall) 45 extending horizontally from the upper end of the inner sidewall 43 toward the outer side of the vehicle and connecting to the outer sidewall 44.

[0052] The mounting base 41 of the seal 40 is a plate-shaped part that extends in an arched shape, parallel to the vertical plate 6. A lower connecting wall 45, one end of which is connected to the lower side of the outer side wall 44 (below the center in the vertical direction), is connected to the lower part of the mounting base 41. An upper connecting wall 46, one end of which is connected to the upper side of the outer side wall 44 (above the center in the vertical direction), is connected to the upper part of the mounting base 41. The upper part of the outer side wall 44 extends to a position higher than the upper connecting wall 46, and the head of the clamp K is accommodated in the space enclosed by the mounting base 41, the lower connecting wall 45, the upper connecting wall 46, and the outer side wall 44. Therefore, the mounting position of the seal 40 relative to the vertical plate 6 is higher than the position of the sealing hollow portion 42.

[0053] In the sealed hollow portion 42 of the seal 40, the connecting portion 47, which connects the lower part of the inner sidewall 43 and the lower part of the outer sidewall 44, is a lip-shaped portion extending from top to bottom. It has a roughly tongue-shaped cross-section and its thickness gradually decreases from top to bottom in the inward and outward directions of the vehicle. In addition, the lower end of the connecting portion 47 extends to a position lower than that of the wheel arch portion 5 to prevent mud and the like from splashing from the tire 2 to the outer side of the vehicle.

[0054] Furthermore, a sealing lip 48 is provided on the upper part of the inner sidewall 43 of the sealed hollow portion 42, extending downward and inward, with its front end in elastic contact with the vertical plate 6, to prevent mud and the like from the tire 2 from entering upward between the mounting base 41 of the seal 40 and the vertical plate 6. The thickness of the sealing lip 48 in the inward and outward directions is smaller than the thickness of the connecting portion 47.

[0055] Furthermore, a concave portion 49 is formed on the inner side of the inner sidewall 43 near the root of the sealing lip 48, which reduces the load on the sealing hollow portion 42 to prevent the door from closing poorly.

[0056] Without specific limitations, the seal 40 is formed of a foamed material of rubber or resin. In the case of rubber, EPDM (ethylene propylene rubber) can be cited, and in the case of resin, TPO (olefin thermoplastic resin) can be cited, but it is not limited to these.

[0057] Alternatively, the specific gravity of the mounting base 41, the lower connecting wall 45, and the upper connecting wall 46 can be set higher than that of other parts.

[0058] On the other hand, the protective plate 30 is made of hard resin, such as Figure 3 As shown, it includes: a mounting plate portion 31, which is a plate extending in the vertical direction and is mounted on the inner periphery of the door 1; a cover plate portion 32, which extends horizontally from the lower part of the mounting plate portion 31 toward the outer side of the vehicle and abuts against and covers the portion H from the lower side, wherein the portion H is a portion formed by the front ends of the inner panel 1a and the outer panel 1b constituting the door 1 being rolled together; an inclined plate portion 33, which extends obliquely downward from the lower part of the mounting plate portion 31 toward the inner side of the vehicle; and a middle plate portion 34, which extends horizontally from the mounting plate portion 31 toward the outer side of the vehicle at a position higher than the cover plate portion 32.

[0059] When the door 1 is closed, the inclined plate portion 33 extends between the wheel arch portion 5 and the upper surface of the tire 2, and the front end portion 33a of the inclined plate portion 33 is located slightly inside the vehicle than the position of the vertical plate 6.

[0060] Furthermore, when the door 1 is closed, the upper side of the inclined plate portion 33 of the guard plate 30 elastically contacts the lower part of the connection portion 47 between the inner side wall 43 and the outer side wall 44 of the seal 40.

[0061] At this time, the lower part of the connecting part 47 bends inward and elastically contacts the upper side of the inclined plate part 33 of the guard plate 30. Therefore, the outer side of the lower part of the connecting part 47 elastically contacts the inclined plate part 33, thereby preventing mud and other substances from the tire 2 from adhering.

[0062] Here, although it is unavoidable that mud or other substances may adhere to the vehicle in the area from the inner side of the connecting part 47 to the outer side of the sealing lip 48, there is almost no risk of clothes getting dirty when occupants enter the vehicle, even if trousers, skirts, or other clothing come into contact with the outer surface of the sealing part 40.

[0063] In addition, the appearance will not be affected by the presence of stains on the side of the car body (sealing) that can be directly seen when the car door is opened.

[0064] Furthermore, the connection 47 between the inner sidewall 43 and the outer sidewall 44 of the seal 40 is a lip-shaped portion extending downwards, with a roughly tongue-shaped cross-section. Its thickness gradually decreases from top to bottom in the inward / outward direction. Because this portion elastically contacts the inclined plate portion 33 of the guard plate 30, excessive compressive load on the seal 40 is prevented. Additionally, excessive deformation of the inclined plate portion 33 of the guard plate 30 during elastic contact is prevented, minimizing the deformation of the guard plate 30 and preventing aesthetic deterioration. Simultaneously, the sealing function of the seal 40 is stabilized.

[0065] It should be noted that in this embodiment, the connecting portion 47, which connects the lower part of the inner sidewall 43 to the lower part of the outer sidewall 44, in the seal 40 is formed as a lip extending downwards, and has a generally tongue-shaped cross-section. Furthermore, its thickness gradually decreases from top to bottom in the inward / outward direction. However, as... Figure 4 As shown, the connecting part 47 can also be configured such that the lower part of the inner sidewall 43 is simply connected to the lower part of the outer sidewall 44, without extending downward.

[0066] In this case, if the connecting part 47 is in elastic contact with the inclined plate part 33 of the guard plate 30, the compressive load of the seal 40 will increase. However, by forming a concave part 49 on the inner side of the inner side wall 43 near the root of the sealing lip 48, the load on the sealing hollow part 42 is reduced, and the door closure performance is prevented from deteriorating.

[0067] In addition, such as Figure 3 As shown, as long as the inclined plate portion 33 of the guard plate 30 extends between the wheel arch portion 5 and the upper surface of the tire 2 when the door 1 is closed, and the front end portion 33a of the inclined plate portion 33 is located further inward than the position of the vertical plate 6, the lower end of the connecting portion 47 can also be positioned as follows. Figure 4 As shown, it is located at a position equal to or higher than that of the wheel arch 5.

[0068] Furthermore, if the structure can be achieved through the shape and material of the sealed hollow portion 42 such that the compressive load on the seal 40 does not increase excessively when the connecting portion 47 is in elastic contact with the inclined plate portion 33 of the guard plate 30, then the formation of the concave portion 49 can be omitted. For example, it is also possible to... Figure 3 The seal 40 shown does not have a concave portion 49 specifically formed.

[0069] Alternatively, the sealing lip 48 can be omitted.

[0070] In addition, in this embodiment, when the door 1 is closed, the connecting portion 47 of the seal 40 is made to elastically contact the inclined plate portion 33 of the guard plate 30 installed on the inner side of the door 1. However, the connecting portion 47 of the seal 40 may also be made to elastically contact a guard plate that does not have the shape of the inclined plate portion 33, or it may be made to elastically contact a component that replaces the guard plate or to elastically contact the inner side of the door 1 directly.
