Description

[Technical Field]

[0001] The present invention relates to a seal structure for a vehicle component. [Background technology]

[0002] Conventionally, a sealing structure of this type is known, for example, as shown in Patent Document 1. In this sealing structure, for example, a first sealing portion is disposed between a sensor cover and a front grille of a vehicle to prevent water from adhering to the front surface of a near-infrared sensor. As such, a typical sealing structure is one in which a sealing member made of an elastic material is disposed between two members to be sealed, that is, a first member and a second member.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-159932 Summary of the Invention [Problem to be solved by the invention]

[0004] The general seal structure described above may be formed by assembling a second member to a first member with a seal member disposed on the outer surface of the first member. In such a case, if the seal member is not positioned on the outer surface of the first member in advance, the second member may be assembled to the first member with the seal member misaligned. This may result in a loss of sealing performance provided by the seal member. [Means for solving the problem]

[0005] Various aspects of the sealing structure for a vehicle component for solving the above problems will be described below. [Mode 1] A sealing structure for a vehicle part comprising: a first member having an annular first peripheral wall and a first opening; a second member having an annular second peripheral wall and a second opening, which covers the first member by inserting the first member through the second opening so that the second peripheral wall is positioned outside the first peripheral wall; and a sealing member which is annular and made of an elastic material and is placed on the outer surface of the first peripheral wall to seal between the first peripheral wall and the second peripheral wall, the sealing member having a base portion whose inner surface contacts the outer surface of the first peripheral wall and a lip portion protruding from the outer surface of the base portion and whose tip contacts the inner surface of the second peripheral wall, wherein the outer surface of the first peripheral wall is provided with a protrusion for positioning the sealing member in the insertion direction of the first member.

[0006] According to the above configuration, when the seal member is disposed on the outer surface of the first peripheral wall, the protrusions allow the seal member to be positioned in the insertion direction of the first member. This allows the seal member to be disposed accurately in the correct position between the first peripheral wall and the second peripheral wall, ensuring the sealing performance of the seal member.

[0007] [Aspect 2] A sealing structure for a vehicle part described in [Aspect 1], characterized in that the first member has a first bottom wall, the second member has a second bottom wall, and the inside of the second peripheral wall on the second bottom wall is provided with an annular rib having an outer surface that can contact the inner surface of the first peripheral wall when the first member is inserted into the second member.

[0008] According to the above configuration, the second member can be reinforced by the rib. Furthermore, when inserting the first member into the second member, the outer surface of the rib slides against the inner surface of the first peripheral wall, thereby facilitating the insertion of the first member into the second member. Furthermore, after inserting the first member into the second member, the inner surface of the first peripheral wall comes into contact with the outer surface of the rib, thereby positioning the second member relative to the first member in the surface direction of the second bottom wall. This ensures contact pressure of the lip portion of the sealing member against the inner surface of the second peripheral wall.

[0009] [Aspect 3] A sealing structure for a vehicle part described in [Aspect 1] or [Aspect 2], characterized in that the convex portions are arranged at least one on each side of the central portion of the first member on the first peripheral wall in opposing positions.

[0010] According to the above configuration, the positioning of the seal member when inserting the first member into the second member can be performed in a well-balanced manner by the convex portion. [Aspect 4] A sealing structure for a vehicle part described in any one of [Aspect 1] to [Aspect 3], characterized in that a plurality of the lip portions are protruded from the outer surface of the base portion so as to be aligned at intervals.

[0011] The above configuration can contribute to improving the sealing performance of the seal member. [Effects of the Invention]

[0012] The present invention can ensure the sealing performance of the sealing member. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] (First embodiment) The first embodiment will be described below with reference to the drawings. <Vehicle parts 11> 1 and 2, the vehicle component 11 accommodates an object 12 that is vulnerable to water, such as various sensors, such as a millimeter-wave sensor, mounted on a vehicle, or a circuit board, inside the vehicle component 11, thereby protecting the object 12 from water. That is, the vehicle component 11 protects the object 12 from water by its sealing structure. The vehicle component 11 includes a first member 13, a second member 14, a sealing member 15, and a protrusion 16. The vehicle component 11 has, for example, an elliptical shape in a plan view.

[0015] In the following description, the up-down direction is based on the up-down direction of the vehicle component 11 shown in Fig. 1. Therefore, the vehicle component 11 of this embodiment has a configuration in which the second member 14 is assembled to the upper side of the first member 13.

[0016] <First member 13 and protruding portion 16> 1 and 2, the first member 13 is made of, for example, synthetic resin and has a bottomed elliptical box shape. That is, the first member 13 has an elliptical first bottom wall 17, an elliptical annular first peripheral wall 18 provided on the upper surface of the first bottom wall 17, and a first opening 19 opening at the upper end of the first peripheral wall 18. The peripheral edge of the first bottom wall 17 protrudes outward beyond the first peripheral wall 18 and has a first peripheral edge 20 adjacent to the outer periphery of the first peripheral wall 18, and a second peripheral edge 21 adjacent to the outer periphery of the first peripheral edge 20.

[0017] The height of the upper surface of the first peripheral edge portion 20 is higher than the height of the upper surface of the second peripheral edge portion 21. In other words, a step surface 22 is formed between the first peripheral edge portion 20 and the second peripheral edge portion 21. The height of the upper surface of the first bottom wall 17 inside the first peripheral wall 18 is the same as the height of the upper surface of the second peripheral edge portion 21. The contained item 12 is arranged in a fixed state inside the first peripheral wall 18 on the upper surface of the first bottom wall 17. The height of the contained item 12 is lower than the height of the first peripheral wall 18.

[0018] The outer surface of the first peripheral wall 18 is parallel to the vertical direction. The inner surface of the first peripheral wall 18 is slightly inclined relative to the vertical direction so that the inner surface is positioned more outward as it goes upward. A rectangular parallelepiped protrusion 16 is provided at the upper end of the outer surface of the first peripheral wall 18. The protrusions 16 are arranged one by one at positions on the outer surface of the first peripheral wall 18 facing each other across the center of the first member 13.

[0019] That is, the two protrusions 16 are arranged near an extension of the minor axis of the ellipse formed by the first peripheral wall 18 in a plan view. The protrusions 16 protrude radially outward from the outer surface of the first peripheral wall 18. The protrusions 16 are formed integrally with the first peripheral wall 18, for example.

[0020] <Second member 14> 1, the second member 14 is made of, for example, synthetic resin and has a bottomed elliptical box shape. That is, the second member 14 has an elliptical second bottom wall 25, an elliptical annular second peripheral wall 26 provided on the lower surface of the second bottom wall 25, and a second opening 27 opening at the lower end of the second peripheral wall 26. By inserting the first member 13 through the second opening 27, the second member 14 covers the first member 13 so that the second peripheral wall 26 is located outside the first peripheral wall 18.

[0021] When the first member 13 is covered with the second member 14, the lower surface of the second peripheral wall 26 faces the upper surface of the second peripheral edge portion 21 of the first member 13. In this case, a small gap is formed between the lower surface of the second peripheral wall 26 and the upper surface of the second peripheral edge portion 21. An elliptical annular rib 28 having an outer surface that can come into contact with the inner surface of the first peripheral wall 18 when the first member 13 is inserted into the second member 14 from the second opening 27 is provided on the inner side of the second peripheral wall 26.

[0022] When the first member 13 is inserted into the second member 14 through the second opening 27, the lower surfaces of the ribs 28 face the upper surface of the first bottom wall 17 on the inside of the first peripheral wall 18. In this case, a small gap is formed between the lower surfaces of the ribs 28 and the upper surface of the first bottom wall 17 on the inside of the first peripheral wall 18. The outer surfaces of the ribs 28 are slightly inclined in the vertical direction so that they are positioned more inward as they extend downward. The inner surfaces of the ribs 28 are slightly inclined in the vertical direction so that they are positioned more outward as they extend downward.

[0023] The lower surface of the second bottom wall 25 between the second peripheral wall 26 and the rib 28 faces the upper surface of the first peripheral wall 18 when the first member 13 is inserted into the second member 14 through the second opening 27. In this case, a small gap is formed between the lower surface of the second bottom wall 25 between the second peripheral wall 26 and the rib 28 and the upper surface of the first peripheral wall 18. Furthermore, in this case, a small gap is formed between the inner surface of the first peripheral wall 18 and the outer surface of the rib 28.

[0024] <Sealing member 15> 1, sealing member 15 has an elliptical ring shape and is made of an elastic material such as silicone rubber. The elasticity of sealing member 15 causes it to be in close contact with the outer surface of first peripheral wall 18, thereby sealing between first peripheral wall 18 and second peripheral wall 26 when first member 13 is inserted into second member 14 through second opening 27.

[0025] The seal member 15 has an elliptical annular base portion 29 whose inner surface contacts the outer surface of the first peripheral wall 18, and a plurality of (three in this example) elliptical annular lip portions 30 that protrude from the outer surface of the base portion 29 and whose tip portions contact the inner surface of the second peripheral wall 26. The lower surface of the base portion 29 contacts the upper surface of the first peripheral edge portion 20. The upper surface of the base portion 29 faces the lower surface of the protrusion 16 with a small gap between them.

[0026] Therefore, when the sealing member 15 is attached to the outer surface of the first peripheral wall 18 by its elastic force, the protrusions 16 position the sealing member 15 in the vertical direction, which is the direction in which the first member 13 is inserted into the second member 14. That is, when the sealing member 15 is attached to the outer surface of the first peripheral wall 18, the sealing member 15 is positioned below the protrusions 16, thereby positioning the sealing member 15 in the vertical direction.

[0027] The plurality of elliptical annular lip portions 30 are arranged at equal intervals in the vertical direction between the upper and lower ends of the outer surface of the base portion 29 and protrude outward. The tip portions of the lip portions 30 protrude outward beyond the stepped surface 22.

[0028] <Operation of the First Embodiment> Next, the operation of assembling the vehicle component 11 will be described. 3, when assembling the vehicle component 11, first, the sealing member 15 is placed on the outer surface of the first peripheral wall 18 of the first member 13 by its elastic force. At this time, the sealing member 15 is placed on the outer surface of the first peripheral wall 18 so that the upper end of the sealing member 15 is positioned below the protrusion 16. In this way, the sealing member 15 is placed on the outer surface of the first peripheral wall 18 with its positioning in the up-down direction being correct.

[0029] Next, the object to be contained 12 is placed and fixed in the center of the upper surface of the first bottom wall 17 inside the first peripheral wall 18 of the first member 13. Next, the second member 14 is moved so as to cover the first member 13 from above, thereby inserting the first member 13 into the second member 14 through the second opening 27. Then, as shown in FIG. 1 , the object to be contained 12 is inserted into the space inside the rib 28 of the second member 14, and the first peripheral wall 18 with the sealing member 15 arranged on its outer surface is inserted into the space between the rib 28 and the second peripheral wall 26 of the second member 14.

[0030] Then, when the second member 14 is completely assembled to the first member 13, the vehicle component 11 shown in Fig. 1 is assembled. At this time, as described above, the sealing member 15 is disposed on the outer surface of the first peripheral wall 18 with its positioning determined in the vertical direction by the protrusions 16, so the sealing member 15 is accurately disposed in the correct position between the first peripheral wall 18 and the second peripheral wall 26. Therefore, the sealing performance provided by the sealing member 15 between the first peripheral wall 18 and the second peripheral wall 26 in the vehicle component 11 is ensured.

[0031] <Effects of the first embodiment> According to the first embodiment described above in detail, the following effects are achieved. (1-1) In the seal structure of the vehicle component 11, the outer surface of the first peripheral wall 18 is provided with a protrusion 16 for positioning the seal member 15 in the insertion direction of the first member 13.

[0032] According to the above configuration, due to the above-described <Action of the First Embodiment>, when the seal member 15 is disposed on the outer surface of the first circumferential wall 18, the convex portion 16 can determine the position of the seal member 15 in the up-down direction. Therefore, when the second member 14 is completely attached to the first member 13 to assemble the vehicle component 11 shown in FIG. 1 , the seal member 15 can be accurately disposed in the correct position between the first circumferential wall 18 and the second circumferential wall 26. Therefore, the sealing performance of the seal member 15 between the first circumferential wall 18 and the second circumferential wall 26 in the vehicle component 11 can be ensured.

[0033] (1-2) In the sealing structure of the vehicle part 11, an annular rib 28 having an outer surface that can contact the inner surface of the first peripheral wall 18 when the first member 13 is inserted into the second member 14 is provided on the inside of the second peripheral wall 26 of the second bottom wall 25.

[0034] According to the above configuration, the second member 14 can be reinforced by the ribs 28. Furthermore, when inserting the first member 13 into the second member 14, the outer surface of the ribs 28 slides against the inner surface of the first peripheral wall 18, thereby smoothly inserting the first member 13 into the second member 14. Furthermore, after inserting the first member 13 into the second member 14, the inner surface of the first peripheral wall 18 comes into contact with the outer surface of the ribs 28, thereby positioning the second member 14 relative to the first member 13 in the planar direction of the second bottom wall 25, which is the horizontal direction perpendicular to the up-down direction. This ensures contact pressure of the lip portion 30 of the sealing member 15 against the inner surface of the second peripheral wall 26.

[0035] (1-3) In the seal structure of the vehicle component 11, the protrusions 16 are arranged one by one at positions on the first circumferential wall 18 facing each other with the center of the first member 13 in between. According to the above configuration, the positioning of the seal member 15 when the first member 13 is inserted into the second member 14 can be performed in a well-balanced manner by the protrusion 16.

[0036] (1-4) In the seal structure of the vehicle component 11, a plurality of lip portions 30 are provided on the outer surface of the base portion 29 so as to protrude and be aligned at intervals. The above configuration can contribute to improving the sealing performance of the seal member 15.

[0037] (Second embodiment) As shown in Fig. 4, this second embodiment is the same as the first embodiment except that an extension 24 is provided at the tip of the protrusion 16 in the first embodiment. Therefore, in this second embodiment, only the differences from the first embodiment will be described, and a description that overlaps with the first embodiment will be omitted. In addition, in this second embodiment, the same members as in the first embodiment will be assigned the same reference numerals.

[0038] <Extension part 24> As shown in Figures 4 and 5, the extension portion 24 is provided integrally with the protrusion 16 at the tip of the protrusion 16. The extension portion 24 has a rectangular plate shape and extends from the tip of the protrusion 16 along the circumferential direction of the first peripheral wall 18. The extension portion 24 is disposed on an extension line of the minor axis of the ellipse formed by the first peripheral wall 18 in a plan view. The extension portion 24 faces the outer surface of the first peripheral wall 18 in the radial direction of the first peripheral wall 18. The lower end of the extension portion 24 is located lower than the lower end of the protrusion 16.

[0039] <Sealing member 15> 6, the outer surface of the tip of base portion 29 of seal member 15 in the insertion direction of first member 13 into second member 14, i.e., the outer surface of the upper end portion of base portion 29, faces the inner surface of extension portion 24. The upper end portion of base portion 29 is located between the outer surface of the upper end portion of first circumferential wall 18 and the inner surface of extension portion 24.

[0040] 4, even if the upper end of base portion 29 is moved toward second peripheral wall 26, which is the outer periphery, when first member 13 is inserted into second member 14 through second opening 27, the outer surface of the upper end of base portion 29 abuts against the inner surface of extension portion 24. Therefore, extension portion 24 prevents the upper end of base portion 29 from moving toward the outer periphery.

[0041] <Operation of the Second Embodiment> Next, the operation of assembling the vehicle component 11 will be described. 6, when assembling the vehicle component 11, first, the sealing member 15 is placed on the outer surface of the first peripheral wall 18 of the first member 13 by its elastic force. Next, the contained item 12 is placed and fixed in the center of the upper surface of the first bottom wall 17 inside the first peripheral wall 18 of the first member 13. Next, the second member 14 is moved so as to cover the first member 13 from above, and the first member 13 is inserted into the second member 14 through the second opening 27.

[0042] 7, the object to be contained 12 is inserted into the space inside the rib 28 of the second member 14, and the first peripheral wall 18 with the sealing member 15 disposed on its outer surface is inserted into the space between the rib 28 and the second peripheral wall 26 of the second member 14. At this time, the outer surface of the rib 28 is slid along the inner surface of the first peripheral wall 18, thereby guiding the movement of the second member 14 relative to the first member 13.

[0043] Furthermore, at this time, due to friction between the inner surface of the second peripheral wall 26 and the tip of the lip portion 30 of the seal member 15, the lip portion 30 is pulled downward as the second member 14 moves. This causes a force to act on the seal member 15, tending to tilt it from its upper end toward the outer periphery. As a result, the seal member 15 tilts from its upper end toward the outer periphery, but the outer surface at the upper end of the base portion 29 abuts against the inner surface of the extension portion 24, preventing it from tilting further toward the outer periphery from its upper end.

[0044] Subsequently, the second member 14 is moved downward to completely assemble the second member 14 to the first member 13, thereby assembling the vehicle component 11 shown in Fig. 4. At this time, as described above, a force acts on the seal member 15 to cause it to tilt outward from its upper end, but because the outer surface of the upper end of the base portion 29 has already abutted against the inner surface of the extension portion 24, the seal member 15 will not tilt outward from its upper end any further.

[0045] Therefore, in the vehicle component 11, the seal member 15 is disposed in the correct position and in the correct shape between the first peripheral wall 18 and the second peripheral wall 26. As a result, the sealing performance of the seal member 15 between the first peripheral wall 18 and the second peripheral wall 26 in the vehicle component 11 is ensured.

[0046] Furthermore, when the second member 14 is completely assembled to the first member 13, the air inside the ribs 28 of the second member 14 is discharged to the outside through the gap between the lower surface of the ribs 28 and the upper surface of the first bottom wall 17 inside the first peripheral wall 18, the gap between the outer surface of the ribs 28 and the inner surface of the first peripheral wall 18, the gap between the lower surface of the second bottom wall 25 between the second peripheral wall 26 and the ribs 28 and the upper surface of the first peripheral wall 18, and the gap between the lower surface of the second peripheral wall 26 and the upper surface of the second peripheral edge portion 21.

[0047] Therefore, there is less air resistance between the first member 13 and the second member 14 when they are assembled together. This reduces the force required when assembling the second member 14 to the first member 13, improving workability.

[0048] Incidentally, if the air inside the ribs 28 of the second member 14 is not discharged to the outside when assembling the second member 14 to the first member 13, the resistance caused by the air existing between them will increase when assembling the second member 14 to the first member 13. This increases the force required to assembling the second member 14 to the first member 13, reducing workability.

[0049] <Effects of the second embodiment> According to the second embodiment described above in detail, in addition to the effects described in (1-1) to (1-4) above, the following effects are achieved.

[0050] (2-1) The sealing structure of the vehicle part 11 includes an extension portion 24 provided at the tip of the protrusion 16 provided on the outer surface of the first peripheral wall 18, which suppresses movement of the upper end of the base portion 29, which is the tip of the base portion 29 of the sealing member 15 in the insertion direction of the first member 13, toward the outer periphery.

[0051] According to the above configuration, due to the above <Action of the Second Embodiment>, the extension portion 24 suppresses movement of the upper end portion of the base portion 29 of the seal member 15 toward the outer periphery when the second member 14 is assembled to the first member 13. Therefore, in the vehicle component 11, the seal member 15 can be disposed in the correct position and in the correct shape between the first circumferential wall 18 and the second circumferential wall 26. Therefore, the seal provided by the seal member 15 between the first circumferential wall 18 and the second circumferential wall 26 in the vehicle component 11 can be ensured.

[0052] (2-2) In the seal structure of the vehicle component 11, the extensions 24 are arranged one by one at positions on the first circumferential wall 18 facing each other with the central portion of the first member 13 therebetween, with the protrusions 16 interposed therebetween.

[0053] According to the above configuration, when the first member 13 is inserted into the second member 14, the extension portion 24 can prevent the seal member 15 from falling toward the second peripheral wall 26, which is the outer periphery of the seal member 15, in a balanced manner. <Example of change> The above-described embodiments can be modified as follows: Furthermore, the above-described embodiments and the following modifications can be combined with each other within the scope of technical compatibility.

[0054] The plurality of lip portions 30 do not necessarily have to be protruding from the outer surface of the base portion 29 so as to be aligned at equal intervals. In other words, the plurality of lip portions 30 may be protruding from the outer surface of the base portion 29 so as to be aligned at different intervals from each other.

[0055] The number of lip portions 30 protruding from the outer surface of the base portion 29 may be one, two, or four or more. Two or more protrusions 16 may be arranged on the first circumferential wall 18 at positions facing each other with the center of the first member 13 in between.

[0056] A plurality of protrusions 16 may be arranged at appropriate intervals around the entire circumference of the first peripheral wall 18 . In the second member 14, the rib 28 may be omitted. The first bottom wall 17 may be omitted from the first member 13, and the second bottom wall 25 may be omitted from the second member 14. In this case, the first member 13 and the second member 14 are both cylindrical.

[0057] The shape of the vehicle component 11 in plan view is not limited to an ellipse, but may be, for example, a perfect circle, or a polygonal shape such as a rectangle or a hexagon. The vehicle component 11 is not limited to being used in a state in which the first member 13 and the second member 14 are aligned vertically, but may also be used in a state in which the first member 13 and the second member 14 are aligned horizontally, for example, perpendicular to the vertical direction.

[0058] The protrusion 16 may be configured as a separate member from the first circumferential wall 18. In this case, the protrusion 16 is fixed to the first circumferential wall 18 using, for example, screws or adhesive. The extension 24 may be provided so as to extend downward from the tip of the protrusion 16. In this case, the protrusion 16 may be provided on the first peripheral wall 18 so as to extend around the entire circumference of the first peripheral wall 18. [Explanation of symbols]
