Description

TECHNICAL BACKGROUND Area of ​​the invention

[0001] The present invention relates to a vehicle with a sealing profile structure, wherein opposing sliding doors are mounted on the vehicle, and in particular to a vehicle on which opposing sliding doors are mounted, wherein the sealing profile structure makes it possible to seal a vehicle body and a door without changing a mounting position of a cowl crossbar, even if a front door is designed as a sliding door, by using a curved section of a body sealing profile. Description of the related technique

[0002] In general, doors for opening and closing a passenger compartment have front doors, which are arranged longitudinally at the front of the vehicle, and rear doors, which are arranged longitudinally at the rear of the vehicle.

[0003] In recent years, the need for a fully opening doorway, enabling a disabled person to be easily accommodated in the vehicle and making it easy to load items, has become an important issue, and as a result, it is necessary to arrange sliding doors that are opened and closed by sliding sideways.

[0004] Not only is the back door designed as a sliding door, but also the front door, so that the back door and the front door can be opened or closed in opposite directions.

[0005] In cases where the front door is also designed as a sliding door, an opening flange must be moved forward for user convenience when entering or exiting the vehicle. This relocation of the opening flange therefore involves modifying a weatherstrip that seals the opening flange.

[0006] With regard to a sealing profile of a vehicle fitted with sliding doors, a conventional sliding door device for a vehicle that moves back and forth in the longitudinal direction of the vehicle to open or close a door opening of a vehicle body has a sliding door that is slidably arranged, a door sealing profile that is attached to the sliding door, a pressure switch that detects an internal pressure of the door sealing profile, and a pneumatic pressure line that connects the door sealing profile and the pressure switch so that the door sealing profile and the pressure switch communicate with each other.

[0007] However, the problem is that the sealing capacity of the sealing profile known from the related technology deteriorates if the front door is designed as a sliding door, the shape of the opening flange changes, and thus the shape of the sealing profile changes to correspond to the changed shape of the opening flange.

[0008] The technical background information contained in this paragraph is intended solely to improve the general understanding of the invention and should in no way be construed as confirmation or suggestion that this information constitutes the prior art already known to a person skilled in the art. SUMMARY

[0009] Several aspects of the present invention are directed to provide a vehicle on which opposing sliding doors are mounted, which has a straight opening flange and which, by using a curved section of a body sealing profile for a sealing profile structure for a vehicle of the related technology, makes it possible to seal a vehicle body and a door without changing a mounting position of a cowl cross member, even if a front door is designed as a sliding door.

[0010] According to the invention, a vehicle is provided with a sealing structure according to claim 1.

[0011] The frame section can be integral with the curved section, and the curved section and the straight section can be connected to the frame section.

[0012] The frame section can be integral with the straight section, and the straight section and the curved section can be connected to the frame section.

[0013] The curved section and the straight section can be joined by injection molding.

[0014] The straight section may include an ineffective sealing section formed in a working space of a roller coupled to the vehicle body.

[0015] The curved section may further include a support attached to a flange formed on an outer plate of the vehicle body.

[0016] The curved section may also have a U-shaped, internal steel element formed in the beam, opening the beam so that the flange can be inserted.

[0017] The curved section may also have a T-shaped, internal steel element formed in the beam, opening the beam so that the flange can be inserted.

[0018] The curved section may also have a T-shaped clip that is inserted into the carrier and penetrates the curved section and the outer plate.

[0019] According to an embodiment of the present invention with the aforementioned configuration, the straight opening flange can be implemented even though the front door is designed as a sliding door, and as a result, it is possible to improve the sealing capacity between the vehicle body and the door.

[0020] According to an embodiment of the present invention, the straight opening flange is implemented and a form of a crash pad coupled to the opening flange is also designed in a straight form, resulting in the advantage that an external appearance is not impaired.

[0021] According to one embodiment of the present invention, the vehicle body and the door are sealed without changing the mounting position of the cowl cross member, and as a result, there is an advantage in that it is possible to prevent vibrations caused by the separation between a central section of the cowl cross member and the mounting position.

[0022] According to an embodiment of the present invention, the assembly unit into which the windshield cross member is inserted is positioned, viewed from above, inside the cavity between the curved part and the straight part in such a way that a circumference of the windshield cross member is sealed without the application of a windshield cross member cover, and as a result there is an advantage in that costs are reduced and the sealing capacity is improved.

[0023] The methods and devices of the present invention have further advantages and features, which will be explained in more detail in the accompanying drawings included in this document and in the following detailed description, which together serve to explain certain principles of the present invention.

[0024] It is noted that the accompanying drawings are not necessarily to scale and represent a simplified depiction of various features illustrating the basic principles of the present invention. The specific design features of the present invention contained herein, including, for example, specific dimensions, orientations, locations, and shapes, are partly determined by the specific intended application and operating environment.

[0025] In the figures, reference numerals refer to identical or equivalent parts of the present invention in the different figures of the drawing. DETAILED DESCRIPTION

[0026] Detailed reference will now be made to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. Although the present invention(s) is / are described in conjunction with exemplary embodiments of the present invention, it should be noted that this description is not intended to limit the present invention(s) to these exemplary embodiments. The present invention(s), on the contrary, is / are intended to include not only the exemplary embodiments of the present invention, but also various alternatives, modifications, and further embodiments that may fall within the scope and protection of the present invention as defined by the accompanying claims.

[0027] The present invention is described in detail below with reference to the accompanying drawings. However, the present invention is not limited or restricted by exemplary embodiments. Identical reference numerals in the respective drawings refer to elements that perform essentially the same functions.

[0028] Fig. 1A is a view that exemplifies a condition in which an opening flange 10 and a body sealing profile 200, which is mounted on the opening flange, are displaced in one direction towards the front of a vehicle and are mounted in a case in which a front door is designed as a sliding door.

[0029] In a case where the front door and a rear door of the vehicle are mounted in such a way that they can be pushed in opposite directions, it is necessary to ensure maximum opening dimensions of the doors to prevent a user's foot from becoming trapped in the door when the user is entering or exiting the vehicle.

[0030] With reference to Fig. However, in the case of the front door, the opening flange 10 can be moved towards the front of the vehicle to ensure an opening dimension of the front door.

[0031] The relocation of the opening flange 10 is accompanied by the modification of the body sealing profile 200, which is mounted on the opening flange 10 and seals a gap between a vehicle body 1 and the door when the door is closed.

[0032] Therefore, the straight seal 2 of the related technique is changed to a curved seal along the opening flange 10.

[0033] If the body sealing profile 200 is not modified according to the shape of the opening flange 10, a serious problem regarding water tightness may occur because the opening flange 10 and the body sealing profile 200 are spaced apart from each other.

[0034] Below a dashboard 5, a mounting unit 3 is positioned, allowing a cowl crossmember to be inserted into it, and is mounted to the vehicle body 1 to connect the cowl crossmember to the vehicle body 1. In the related technique, the mounting unit 3 can be positioned on the rear side of the straight seal 2, and fastening units 31, which mount the mounting unit 3 to the vehicle body 1, can also be positioned on the rear side of the straight seal 2.

[0035] Fig. Figure 1B is a view illustrating an exemplary state in which the assembly unit 3, into which the cross member is inserted, is relocated, in the case where the front door is designed as a sliding door.

[0036] Referring to Fig. 1B, the relocation of the opening flange 10 towards the front of the vehicle must be accompanied by the relocation of the mounting unit 3.

[0037] Like the opening flange 10, the mounting unit 3 is also moved in the direction towards the front of the vehicle, so that the fastening unit 31, which is moved forward, and an insertion section 33, into which the cowl cross member is inserted, are spaced apart from each other in the longitudinal direction of the vehicle body 1.

[0038] In the present case, there is a problem of deterioration of the steering vibration behavior, which is related to the attenuation or damping of steering vibrations caused by the driver's steering operation, since a middle section of the cowl cross member and the fastening units 31 for attaching the cowl cross member to the vehicle body 1 are spaced apart from each other.

[0039] Fig. 2A is a view that exemplifies an interior front of a door panel 7 of the related technique, and Fig. 2B is a view that exemplifies an interior front of a door panel 7 based on a modification of the opening flange 10.

[0040] If the opening flange 10 is moved in the direction towards the front of the vehicle, the external appearance of the door trim 7, which is designed to conform to the opening flange 10 when the door is closed, can be modified.

[0041] The door panel 7 deviates from the shape in the Fig. 2A related technique to the technique shown in Fig. The design shown in 2B is modified by the formation of an additional plate 71 to correspond to the opening flange 10, which is shifted towards the front of the vehicle, and as a result, the external appearance of the same is affected.

[0042] To solve the aforementioned problem, illustrates Fig. 3 a sealing profile structure for a vehicle on which opposing sliding doors are mounted, according to an embodiment of the present invention.

[0043] With reference to Fig. 3 The sealing profile structure for a vehicle on which opposing sliding doors are mounted can, according to an embodiment of the present invention, comprise the body sealing profile 200 and an upper sealing profile 400.

[0044] The body sealing profile 200 is mounted on the opening flange 10 and can seal a gap between the vehicle body 1 and the door. The upper sealing profile 400 is mounted on a roof panel and can seal a gap between the roof panel and the vehicle body 1.

[0045] Fig. Figure 4A is a view that exemplifies a structure of the body sealing profile 200 according to an embodiment of the present invention.

[0046] With reference to Fig. 4A the body sealing profile 200 according to an embodiment of the present invention can have a curved section 220, a straight section 205 and a frame section 210.

[0047] The frame section 210 is connected with intersection points 215 between the curved section 220 and the straight section 205 and can define a frame of the body sealing profile 200.

[0048] The cowl crossmember is inserted into the curved section 220. The curved section 220 is mounted on a lateral side of the mounting unit 3, which is mounted to the vehicle body 1. The curved section 220 is mounted in a curved manner along the vehicle body 1, which is shifted towards the front of the vehicle to ensure the opening dimension of the front door.

[0049] Since the curved section 220 is formed, the modified vehicle body 1 and the body sealing profile 200 are not spaced apart from each other, and the gap between the vehicle body 1 and the door can be sealed.

[0050] The straight section 205 is designed to connect both end sections of the curved section 220 in a straight line. Because the straight section 205 is designed in a straight shape, the straight opening flange 10 can be retained without being moved towards the front of the vehicle.

[0051] Since the opening flange 10 is formed in a straight line, the door panel 7, which is formed to correspond to the opening flange 10, can have the same shape as the door panel 7 of the related technique described in Fig. 2A is shown.

[0052] A cavity 225, which has a void, is formed between the straight section 205 and the curved section 220, and the assembly unit 3 can be positioned inside the cavity when viewed from a top view.

[0053] Since the cavity 225 is formed with the empty space between the straight section 205 and the curved section 220, it is not necessary to move the assembly unit 3 with the fastening units 31, which are arranged to connect the cowl cross member to the vehicle body 1, in the direction towards the front of the vehicle.

[0054] Therefore, the mounting unit 3 can be mounted on the vehicle body 1 through the cavity 225. Since the mounting unit 3 and the central part of the cowl crossmember are spaced apart, there is no deterioration of the steering vibration behavior related to the steering vibrations caused by the user's steering input.

[0055] A door dividing line 500 can be retained as before, and as a result, opposing sliding doors can be maintained without changing a door panel 77 or the door trim 7.

[0056] The straight section 205 can have an ineffective sealing section in a working space of a roller coupled to the vehicle body 1.

[0057] Fig. Figure 4B is a view that exemplifies the interior of opposing sliding doors in which a rail 72 is mounted.

[0058] The rail 72 and the roller can be designed such that the opposing sliding doors slide in opposite directions.

[0059] In the present case, the rail 72, which is mounted on the central section of the vehicle body 1 of the related technology and which enables the roller to open the door, can be mounted inside the door so that the rail 72 is not exposed to the outside.

[0060] In the case where the rail 72 is mounted inside the door, the roller is mounted on the vehicle body 1, corresponding to the rail 72, and the rail 72 allows the roller to slide when the door is opened or closed.

[0061] A door bulkhead bracket 73 of the door with a recessed shape can be mounted in the door to ensure a mounting space for the roller and to accommodate the roller when the door is closed.

[0062] In the case where the door is mounted on the vehicle body 1, part of the straight section 205, which is in contact with the door and corresponds to a height of the door bulkhead support 73 of the door, has the ineffective sealing section.

[0063] Apart from the ineffective sealing section, the straight section 205 can seal the gap between the door and the opening flange 10.

[0064] Fig. Figure 5A is an exemplary view illustrating a state in which the straight section 205 and the frame section 210 are integrally formed according to an embodiment of the present invention. With reference to Fig. 5A the frame section 210 can be formed integrally with the straight section 205, and the straight section 205 and the curved section 220 can be connected to the frame section 210.

[0065] Fig. Figure 5B is a view illustrating by way of example a state in which a curved section and the frame section 210 are integrally formed according to an embodiment of the present invention. With reference to Fig. 5B the frame section 210 can be integrally formed with the curved section 220, and the curved section 220 and the straight section 205 can be connected to the frame section 210.

[0066] In the present case, the curved section 220 and the straight section 205 can be connected in a straight line, since the intersection points 215 are formed by injection molding.

[0067] Fig. Figure 6 is a view illustrating by way of example a state in which the curved section 220 is mounted on the vehicle body 1 according to the embodiment of the present invention. With reference to Fig. 6 the curved section 220 can have a support 201 which is formed on a flange 63 formed on an outer plate 11 of the vehicle body 1.

[0068] Fig. Figure 6A is a view illustrating by way of example a condition in which the curved section 220 according to the embodiment of the present invention is mounted on the vehicle body 1 by means of a U-shaped, inner steel element 61.

[0069] With reference to Fig. 6A the curved section 220 can further include the U-shaped inner steel element 61 which is formed in the support 201 and opens the support 201 in such a way that the flange 63 is inserted.

[0070] The support 201 is open laterally and inserted into an opening 217 formed on a lateral side of the “U”-shaped inner steel element 61, so that the curved section 220 can be mounted on the vehicle body 1.

[0071] Fig. Figure 6B is a view illustrating by way of example a condition in which the curved section 220 according to the embodiment of the present invention is mounted to the vehicle body 1 by a “T”-shaped inner steel element 65.

[0072] With reference to Fig. 6A the curved section 220 can further include the T-shaped inner steel element 65 which is formed in the support 201 and opens the support 201 in such a way that the flange 63 is inserted.

[0073] The support 201 is opened laterally and inserted into an opening 218 formed on a lower side of the “T”-shaped inner steel element 65, and the support 201 is inserted by being bent to a top side of the “T”-shaped inner steel element so that the bent section 220 can be attached to the vehicle body 1.

[0074] Fig. Figure 6C is a view illustrating by way of example a condition in which the curved section 220 according to the embodiment of the present invention is mounted to the vehicle body 1 by a “T”-shaped clip 69.

[0075] With reference to Fig.6C the curved section 220 can further include the “T”-shaped clip 69 which is inserted into the carrier 201 and penetrates the curved section 220 and the outer plate 11.

[0076] The clip 69 is inserted into the vehicle body 1 to penetrate the outer plate 11 from inside the curved section 220, so that the curved section 220 can be mounted on the vehicle body 1.
