Description

[Technical field]

[0001] The present invention relates to a mounting structure for a door cushion. [Background technology]

[0002] A door cushion is provided in a vehicle such as an automobile. When a door that opens and closes an opening in the body is closed, the door cushion is disposed between two panels, a panel on the door side and a panel on the body side. The door cushion is attached to one of the two panels.

[0003] As such a door cushion, for example, one having a main body and a locking portion is known, as shown in Patent Document 1. The main body is made of an elastic body and is arranged on one of the two sides in the thickness direction of the panel to which the door cushion is attached. The locking portion is arranged on the surface of the panel to which the door cushion is attached opposite to the surface on which the main body is located, and is connected to the main body through a hole formed in the panel. When the door is open, the panel is sandwiched between the main body and the locking portion, thereby attaching the door cushion to the panel. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2003-130110 A Summary of the Invention [Problem to be solved by the invention]

[0005] In order to prevent the door from rattling against the body when the vehicle is in a closed state, it is possible to make the main body of the door cushion compressed between the two panels when the door is closed. In this case, as the main body is compressed, the locking part connected to the main body, more specifically, the surface of the locking part facing the panel to which the door cushion is attached, is displaced in a direction away from the panel. As a result, a gap is generated between the panel and the facing surface.

[0006] When the door cushion is new and the elasticity of the body is maintained, the elasticity of the body suppresses the rattling of the door against the body when the door is closed while the vehicle is traveling. However, if the elasticity of the body is lost due to aging or the like, the elasticity of the body can no longer suppress the rattling of the door against the body. As a result, while the vehicle is traveling, the door in the closed state may rattle against the body by an amount corresponding to the gap generated between the panel and the opposing surface. [Means for solving the problem]

[0007] The means for solving the above problems and their effects will be described below. The door cushion mounting structure that solves the above problem is applied to a door cushion that is disposed in a compressed state between two panels, a door-side panel and a body-side panel, when a door that opens and closes an opening in a vehicle body is closed. In this mounting structure, the door cushion is mounted to one of the two panels. The door cushion includes a main body and a locking portion. The main body is disposed on a surface located on one of both sides in the thickness direction of the panel to which the door cushion is mounted, and is compressed between the two panels when the door is closed. The locking portion is disposed on a surface of the panel to which the door cushion is mounted opposite to a surface on which the main body is located, and is connected to the main body through a hole formed in the panel. A surface of the locking portion facing the panel to which the door cushion is mounted is configured to have a gap between the panel and the locking portion when the door is closed. A gap-filling portion is formed on the facing surface and positioned between the panel and the locking portion.

[0008] According to the above configuration, when the door is closed, the main body of the door cushion is disposed in a compressed state between two panels, the panel on the body side and the panel on the door side. The elasticity of this main body suppresses rattling of the door relative to the body. When the main body is compressed as described above, the opposing surface of the engagement portion is displaced in a direction away from the panel to which the door cushion is attached. The gap between the opposing surface and the panel is reduced by the amount of the gap filling portion formed between the opposing surface and the panel. Therefore, even if the elasticity of the main body is lost due to aging or the like, rattling of the door relative to the body that occurs as a result can be suppressed to a small amount corresponding to the gap.

[0009] In the above door cushion mounting structure, the gap filling portion is a rib that protrudes from the opposing surface toward the panel to which the door cushion is attached. The protruding height of the rib from the opposing surface is set to a value that makes it come into contact with the panel when the door is closed.

[0010] With this configuration, when the door is closed and the main body is compressed between the body panel and the door panel, the rib protruding from the opposing surface of the locking part comes into contact with the panel to which the door cushion is attached. This makes it possible to effectively reduce rattling of the door against the body even when the main body loses elasticity due to aging or other reasons.

[0011] In the above door cushion mounting structure, the rib is formed from an elastic body, and is considered to be in contact with the panel to which the door cushion is attached in a natural length state when the door is closed.

[0012] With this configuration, when the door is closed and the main body is compressed between the body panel and the door panel, the rib protruding from the opposing surface of the locking part comes into contact with the panel to which the door cushion is attached in its natural length. Therefore, when the door is left closed for a long time, the rib is less likely to deteriorate and the shim is less likely to lose its elasticity.

[0013] In the above door cushion mounting structure, the locking portion may have a guide portion protruding laterally, and the rib may be formed at a position on the opposing surface away from a position corresponding to the guide portion.

[0014] According to this configuration, when attaching the door cushion to a panel, the guide portion is inserted into the hole in the panel, and the portion of the locking portion that is connected to the guide portion is inserted into the hole, and then the entire locking portion is pushed into the hole. This causes the locking portion to pass through the hole in the panel, and the door cushion is attached to the panel. If a rib is formed on the opposing surface of the locking portion at a position corresponding to the guide portion, when the entire locking portion is pushed into the hole in the panel, the rib is sandwiched between the portion of the locking portion that is inserted into the hole and the panel, making it difficult to push the entire locking portion into the hole. However, since the rib is formed at a position away from the portion of the opposing surface that corresponds to the guide portion, it does not become difficult to push the entire locking portion into the hole as described above.

[0015] In the above door cushion mounting structure, the locking portion includes a guide portion protruding toward the side thereof. A chamfered portion may be formed on the side of the locking portion opposite to the guide portion.

[0016] According to this configuration, when attaching the door cushion to the panel, the guide portion is inserted into the hole in the panel, and the portion of the locking portion that is connected to the guide portion is inserted into the hole, and then the entire locking portion is pushed into the hole. This causes the locking portion to pass through the hole in the panel, and the door cushion is attached to the panel. When the entire locking portion is pushed into the hole as described above, the chamfered portion formed on the side of the locking portion opposite the guide portion makes it easier to push the entire locking portion into the hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, one embodiment of a door cushion mounting structure will be described with reference to Figs. The vehicle shown in FIG. 1 is equipped with a sliding door 11. The sliding door 11 moves horizontally relative to a vehicle body 12 to open and close an opening 13 formed in the body 12. The vehicle is provided with a door cushion 14. When the sliding door 11 is closed, the door cushion 14 is located between the front edge (the left edge in FIG. 1) of the sliding door 11 and the front edge (the left edge in FIG. 1) of the opening 13 in the body 12. The door cushion 14 is intended to prevent the sliding door 11 from rattling when closed while the vehicle is traveling.

[0019] 2 shows an enlarged cross section of the door cushion 14 and its surroundings when the sliding door 11 is closed. When the sliding door 11 is closed, the door cushion 14 is disposed between two panels 15, 16, a panel 15 on the body 12 side and a panel 16 on the sliding door 11 side. The door cushion 14 is attached to the panel 16 on the sliding door 11 side.

[0020] The door cushion 14 includes a main body 17 and a locking portion 18. The main body 17 and the locking portion 18 are formed of an elastic body such as rubber. The main body 17 is disposed on one of the thickness direction sides of the panel 16 on the sliding door 11 side, more specifically, on the surface facing the panel 15 on the body 12 side. The main body 17 is compressed between the two panels 15, 16 when the sliding door 11 is closed. The locking portion 18 is disposed on the surface of the panel 16 opposite to the surface on which the main body 17 is disposed. The locking portion 18 is connected to the main body 17 via a hole 19 formed in the panel 16.

[0021] Next, the main body 17 and the locking portion 18 of the door cushion 14 will be described in detail. <Main body 17> 3 shows the door cushion 14 when the sliding door 11 is open. The main body 17 of the door cushion 14 is formed so that the cross-sectional shape when cut in a direction perpendicular to the center line thereof is a circle larger than the hole 19. The main body 17 includes a lip 20, a recess 21, and a protrusion 22.

[0022] The lip 20 is formed on the outer edge of the end of the main body 17 on the panel 16 side. In the state shown in Figs. 3 and 4, the lip 20 protrudes in a direction away from the center line of the main body 17 and in a direction toward the panel 16. As a result, a gap S1 is formed between the end face of the main body 17 on the panel 16 side and the panel 16 when the sliding door 11 is open.

[0023] The recess 21 is formed at an end of the main body 17 opposite to the end on the panel 16 side. The recess 21 opens in a direction away from the panel 16. The protrusion 22 is formed so as to protrude from the bottom surface of the recess 21. The protrusion 22 protrudes from the opening of the recess 21.

[0024] <Latching portion 18> Fig. 4 shows the door cushion 14 of Fig. 3 rotated 90° around its center line. Fig. 5 shows the locking portion 18 of the door cushion 14 as viewed from the direction of arrows V-V in Fig. 4.

[0025] 3 to 5, the locking portion 18 includes a rib 23, a guide portion 24, and a chamfered portion 25. The portion of the locking portion 18 excluding the rib 23 is formed so that the cross-sectional shape when cut in a direction perpendicular to the center line of the locking portion 18 is a circle larger than the hole 19. A gap S2 is formed between the panel 16 and a surface 18a of the locking portion 18 facing the panel 16.

[0026] The rib 23 is formed to protrude from the opposing surface 18a toward the panel 16. This rib 23 serves as a gap filling portion located between the opposing surface 18a and the panel 16. The guide portion 24 protrudes toward the side of the locking portion 18, that is, in a direction away from the center line of the door cushion 14. The chamfered portion 25 is formed by chamfering the side of the locking portion 18 opposite the guide portion 24, as shown from the two-dot chain line to the solid line in Fig. 3.

[0027] Fig. 6 shows the door cushion 14 when the sliding door 11 is closed. As can be seen from Fig. 6, the rib 23 is formed at a position away from a position corresponding to the guide portion 24 on the opposing surface 18a of the locking portion 18. As shown in Fig. 5, the rib 23 is formed at two positions shifted by 90° around the center line of the locking portion 18 with respect to the guide portion 24.

[0028] As shown in Fig. 6, when the sliding door 11 is closed, the main body 17 is compressed between the two panels 15, 16. This causes the lip 20 to elastically deform, eliminating the gap S1 as shown in Figs. 3 and 4. This elastic deformation of the main body 17 including the lip 20 causes the locking portion 18 connected to the main body 17 to displace in a direction away from the panel 16. As a result, the opposing surface 18a of the locking portion 18 also displaces in a direction away from the panel 16. When the sliding door 11 is closed, the protruding height of the rib 23 from the opposing surface 18a is set to a value at which the rib 23 comes into contact with the panel 16 when in its natural length.

[0029] When the sliding door 11 is opened, the main body 17 is released from the compressed state between the two panels 15, 16. This causes the lip 20 to return from its elastically deformed state to its original state, creating a gap S1 as shown in Figures 3 and 4. This return of the main body 17 including the lip 20 from the above-mentioned elastic deformation causes the locking portion 18 connected to the main body 17 to displace in a direction approaching the panel 16. As a result, the opposing surface 18a of the locking portion 18 also displaces in a direction approaching the panel 16. At this time, the locking portion 18 including the rib 23 is elastically deformed, allowing the above-mentioned displacement of the locking portion 18.

[0030] Next, the function and effect of the door cushion mounting structure in this embodiment will be described. (1) When the sliding door 11 is closed, the main body 17 of the door cushion 14 is disposed in a compressed state between the two panels 15, 16, the panel 15 on the body 12 side and the panel 16 on the sliding door 11 side. The elasticity of the main body 17 suppresses rattling of the sliding door 11 relative to the body 12. When the main body 17 is compressed as described above, the opposing surface 18a of the locking portion 18 of the door cushion 14 is displaced in a direction away from the panel 16 to which the door cushion 14 is attached. A rib 23 protrudes from the opposing surface 18a toward the panel 16. When the opposing surface 18a is displaced in a direction away from the panel 16 as described above, the rib 23 comes into contact with the panel 16. As a result, even when the elasticity of the main body 17 is lost due to aging or the like, rattling of the sliding door 11 relative to the body 12 can be suppressed to a small extent.

[0031] (2) When the sliding door 11 is closed and the main body 17 is compressed between the two panels 15, 16, the rib 23 formed to protrude from the opposing surface 18a of the engaging portion 18 comes into contact with the panel 16 in a natural length state. Therefore, when a long period of time has passed with the sliding door 11 closed, the rib 23 is less likely to deteriorate and lose its elasticity.

[0032] (3) When attaching the door cushion 14 to the panel 16, as shown in Fig. 7, the guide portion 24 is inserted into the hole 19 of the panel 16, and the portion of the locking portion 18 that is connected to the guide portion 24 is inserted into the hole 19. Then, the entire locking portion 18 is pushed into the hole 19. As a result, the locking portion 18 passes through the hole 19 of the panel 16, and the door cushion 14 is attached to the panel 16.

[0033] Here, if rib 23 is formed at a position on opposing surface 18a of locking portion 18 corresponding to guide portion 24, when locking portion 18 is entirely pushed into hole 19 in panel 16, rib 23 is sandwiched between the portion of locking portion 18 inserted into hole 19 and panel 16. This makes it difficult to entirely push locking portion 18 into hole 19.

[0034] However, since the rib 23 is formed at a position away from the portion of the opposing surface 18a that corresponds to the guide portion 24, it does not become difficult to press the entire locking portion 18 into the hole 19 as described above.

[0035] (4) A chamfered portion 25 is formed by chamfering the side of the locking portion 18 of the door cushion 14 opposite the guide portion 24. Therefore, when the entire locking portion 18 is pressed into the hole 19 of the panel 16 as shown in Fig. 7, the chamfered portion 25 formed on the side of the locking portion 18 opposite the guide portion 24 makes it easier to press the entire locking portion 18 into the hole 19.

[0036] The above embodiment can be modified, for example, as follows: The above embodiment and the following modified examples can be combined with each other to the extent that no technical contradiction occurs. The engaging portion 18 of the door cushion 14 does not necessarily need to have the chamfered portion 25 formed thereon.

[0037] The guide portion 24 of the locking portion 18 may be omitted. The position of the rib 23 on the facing surface 18a of the engaging portion 18 may be changed around the center line of the door cushion 14 as appropriate.

[0038] The number of ribs 23 may be one or more than two. The protruding height of the rib 23 from the opposing surface 18a when the sliding door 11 is closed is set to a value at which the rib 23 comes into contact with the panel 16 when in its natural length, but it may also be set to a value at which the rib comes into contact with the panel 16 in a compressed state.

[0039] The height of the rib 23 protruding from the opposing surface 18a when the sliding door 11 is closed may be set to a value that prevents the rib 23 from contacting the panel 16. Even with this configuration, the following advantageous effects can be obtained.

[0040] That is, when the sliding door 11 is closed, the main body 17 of the door cushion 14 is disposed in a compressed state between the two panels 15, 16, the panel 15 on the body 12 side and the panel 16 on the sliding door 11 side. When the main body 17 is compressed as described above, the opposing surface 18a of the locking portion 18 of the door cushion 14 is displaced in a direction away from the panel 16. A rib 23 protrudes from the opposing surface 18a toward the panel 16, and the gap S2 between the opposing surface 18a and the panel 16 is reduced by the amount of the rib 23 formed on the opposing surface 18a. Therefore, even if the elasticity of the main body 17 is lost due to aging or the like, the rattle of the sliding door 11 relative to the body 12 that occurs as a result of this can be reduced by the amount corresponding to the gap S2.

[0041] The locking portion 18 of the door cushion 14 may be made of a material other than rubber, such as resin. In this case, when the sliding door 11 is open, the elasticity of the portion of the main body 17 of the door cushion 14 that is connected to the locking portion 18 presses the locking portion 18 against the panel 16. When the sliding door 11 is closed and the main body 17 is compressed between the panels 15, 16, the locking portion 18 is released from pressing against the panel 16. At this time, it is preferable that the rib 23 contacts the panel 16. Also, the rib 23 may be separated from the panel 16.

[0042] The door cushion 14 may be attached to a panel 15 on the body 12 side. The mounting structure of the door cushion 14 does not necessarily have to be applied to the sliding door 11, but may be applied to doors other than the sliding door 11 in the vehicle. [Explanation of symbols]
