TECHNICAL FIELD
[0001] The utility model relates to the field of automobile parts, and particularly relates to a waterproof cover plate. BACKGROUND
[0002] At present, some holes are formed on automobile sheet metal, wherein the formed holes can be used for allowing wire harness to pass through, so that the wire harness inside the automobile sheet metal can pass out through the holes and be connected with the control switch on the interior trim on the inner side of the automobile sheet metal; and other holes are process holes provided for the convenience of production and processing.
[0003] In order to prevent liquid from entering the automobile interior in rainy days, the waterproof cover plate made of PP or PE material is usually used to block the holes. However, when the waterproof cover plate is installed in the holes, the waterproof cover plate is prone to large deformation, and a gap is formed between the blocking edge of the waterproof cover plate and the inner wall of the hole, so that the waterproof cover plate cannot be tightly attached to each other, and thus the phenomenon of water leakage is easily caused. INVENTION CONTENTS
[0004] The utility model intends to provide a waterproof cover plate to improve the sealing effect of the waterproof cover plate, improve the waterproof effect, and solve the problem of water leakage.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waterproof cover plate, comprising a cover body, an insertion part for being inserted into a hole is integrally arranged on the back surface of the cover body, a recess is arranged on the front surface of the cover body, the recess is sunken into the insertion part, the recess divides the insertion part into a first side part and a second side part for abutting against the inner wall of the hole, a vertical support rib is integrally arranged in the recess, one end of the support rib is integrally fixed on the first side part, and the other end of the support rib is integrally fixed on the second side part.
[0006] The principle and advantages of the scheme are as follows: the waterproof cover plate is installed in the hole of the automobile sheet metal, the insertion part is inserted into the hole, and the side wall of the second side part away from the recess abuts against the inner wall of the hole, so that the hole is blocked. The support rib arranged in the recess supports the second side part between the first side part and the second side part, so that the second side part is prevented from being deformed greatly in the direction of the first side part, the ability of the second side part to resist deformation is improved, the side wall of the second side part away from the recess is tightly abutted against the inner wall of the hole, the blocking quality is ensured, the sealing and waterproof effect is improved, and the problem of water leakage caused by large deformation of the second side part is solved.
[0007] The vertical arrangement of the support ribs in the present scheme is for the convenience of injection molding of the waterproof cover plate, because if the support ribs are arranged horizontally, it is not convenient to injection mold the cavity between the horizontal support ribs and the bottom of the groove, and even if it can be injection molded, it is not convenient for subsequent demolding. On the other hand, compared with horizontal arrangement, the vertical arrangement of the support ribs has a larger contact area with the second side in the vertical direction, which can ensure the supporting effect of the second side and the sealing effect of the waterproof cover plate. The horizontal arrangement of the support ribs only supports the local position (for example, the middle part of the second side) of the second side in the vertical direction of the groove, and the supporting effect is weak, and the waterproof effect is not as good as the vertical arrangement of the support ribs in the present scheme.
[0008] In addition, the support ribs are arranged in the groove, and the support ribs do not fill the entire groove, which does not affect the elasticity of the second side. When the insertion part is inserted into the hole, the second side still has elasticity and slightly deforms, so that the insertion part can be assembled into the hole.
[0009] Preferably, as an improvement, the groove is arranged around the edge of the cover body, and the support ribs are arranged in the groove. By this arrangement, the support ribs are arranged in a ring around the cover body, and the multiple support ribs act on different parts of the second side, so that there is no dead angle of support, and the waterproof effect is guaranteed.
[0010] Preferably, as an improvement, the number of support ribs is 10-20.
[0011] Preferably, as an improvement, the thickness of the support ribs is 1-2mm.
[0012] Preferably, as an improvement, the distance between adjacent two support ribs is 40-80mm.
[0013] Preferably, as an improvement, the depth of the groove is 5-20mm.
[0014] Preferably, as an improvement, the thickness of the second side is 1-3mm.
[0015] Preferably, as an improvement, the second side away from the side of the groove is provided with a clamping groove. By this, when the insertion part is inserted into the hole, the inner wall of the hole is clamped in the clamping groove, and the side of the clamping groove is clamped on the metal plate, so that the insertion part is not easy to separate from the hole, and the stability of the waterproof cover plate covering the hole is improved.
[0016] Preferably, as an improvement, the cover body is provided with a wire harness hole. By arranging the wire harness hole on the cover body, when the waterproof cover plate seals the hole of the metal plate provided with the wire harness, the waterproof cover plate will not hinder the wire harness from passing through the metal plate, and the wire harness in the metal plate can pass through the wire harness hole and be connected with the operation switch on the interior trim part.
[0017] Preferably, as an improvement, the cover material is PP or PE material. BRIEF DESCRIPTION OF DRAWINGS

[0024] The following will be further described in detail through specific embodiments:
[0025] The reference signs in the drawings of the specification include: cover 1, groove 2, support rib 3, second side 5, first side 6, edge 7, clamping groove side 8, insertion part 9, guide slope 10, clamping groove 11.
[0026] Example 1
[0027] In combination Figures 4-5 As shown, there is a waterproof cover plate in the prior art, which includes a cover 1, the material of the cover 1 is PP or PE material, the back of the cover 1 is integrally provided with an insertion part 9 for insertion into a hole, the front of the cover 1 is provided with a groove 2, the groove 2 is sunken into the insertion part 9, and the groove 2 divides the insertion part 9 into a first side 6 and a second side 5 for abutting against the inner wall of the hole. The groove 2 is arranged around the edge 7 of the cover 1. Thus, the setting of the groove 2 makes the first side 6 and the second side 5 have a gap therebetween, and when the waterproof cover plate is inserted into the hole, the second side 5 is abutted by the inner wall of the hole and is adapted to move towards the first side 6, and the second side 5 is elastically deformed so that the insertion part 9 can be normally inserted into the hole. However, during the assembly of the waterproof cover plate, if the operation is improper, the waterproof cover plate may be deformed greatly, at which time a gap appears between the second side 5 of the waterproof cover plate and the inner wall of the hole away from the side wall of the groove 2, and they do not tightly abut against each other, so that the phenomenon of water leakage is easily caused.
[0028] To solve the above problems, the waterproof cover plate is improved in combination with Figures 1-3 and Figure 6 As shown in the drawings, a plurality of support ribs 3 vertically (in the depth direction of the groove 2) are integrally formed in the groove 2, one end of the support rib 3 is integrally fixed on the first side 6, and the other end of the support rib 3 is integrally fixed on the second side 5. The plurality of support ribs 3 are distributed in the groove 2. The number of support ribs 3 is 10-20, and the number of support ribs 3 in the embodiment is specifically 14. The thickness of the support rib 3 is 1-2 mm, and the thickness of the support rib 3 in the embodiment is specifically 1 mm. The distance between the adjacent two support ribs 3 is 40-80 mm, and the distance between the adjacent two support ribs 3 in the embodiment is specifically 60-65 mm. The cross-sectional shape of the groove 2 is V-shaped, the depth of the groove 2 is 5-20 mm, and the depth of the groove 2 in the embodiment is specifically 15 mm; the width of the top of the groove 2 is 8-12 mm, and specifically 9 mm. The thickness of the second side 5 is 1-3 mm, and specifically 2 mm. In combination with Figure 3 As shown in the drawings, the side of the second side 5 away from the groove 2 is provided with a clamping groove 11. In order to make the insertion part 9 more smoothly inserted into the hole, the end of the insertion part 9 is provided with a guide slope 10.
[0029] Therefore, when the waterproof cover plate is installed on the hole of the automobile sheet metal, the insertion part 9 is inserted into the hole, the setting of the guide slope 10 facilitates the insertion of the insertion part 9 into the hole, and in the process of inserting the insertion part 9 into the hole, the second side 5 is slightly close to the first side 6 under the pressure of the inner wall of the hole, and the second side 5 slightly deforms, so that the second side 5 can be inserted into the hole, and the hole will not hinder the insertion of the insertion part 9. When the insertion part 9 is completely inserted into the hole, the inner wall of the hole is clamped in the clamping groove 11, and the clamping groove side 8 is in contact with the edge of the hole, thereby preventing the waterproof cover plate from falling off. At the same time, the support rib 3 supports the second side 5, so that the second side 5 will not move to the first side 6 by a large distance, the second side 5 will not deform greatly, and the second side 5 will be tightly pressed against the inner wall of the hole, thereby avoiding the phenomenon of large gap between the second side 5 and the inner wall of the hole.
[0030] In addition, in other embodiments, when the waterproof cover plate is used to block the hole provided with the wire harness, the cover body 1 can also be provided with a wire harness hole (not shown in the drawings). In this way, the wire harness inside the sheet metal can pass out through the wire harness hole, and the waterproof cover plate will not affect the wire harness passing out from the sheet metal. After the wire harness passes out from the wire harness hole, the gap between the wire harness and the inner wall of the wire harness hole can be sealed by filling sealant or a sealing ring, so as to avoid water leakage at the wire harness hole.
[0031] For the size and shape of the waterproof cover plate in the embodiment, the above-mentioned limitation is only part of the implementation, and in actual implementation, it can be set according to holes of different shapes and sizes.
[0032] Embodiment 2
[0033] The embodiment is further improved on the basis of embodiment 1, and an elastic sealing ring is sleeved in the clamping groove 11. The elastic sealing ring is made of rubber material, and the width of the elastic sealing ring is adapted to the width of the clamping groove 11. The thickness of the elastic sealing ring is less than the depth of the clamping groove 11 (for example, the depth of the clamping groove 11 is 1 mm, and the thickness of the elastic sealing ring is 0.5 mm), so that the elastic sealing ring will not protrude from the clamping groove 11, and there is still space in the clamping groove 11 to accommodate the inner wall of the hole. Thus, when the waterproof cover plate is covered on the hole, the inner wall of the hole is located in the clamping groove 11, the elastic sealing ring acts on the inner wall of the clamping groove 11, and the elastic sealing ring is clamped by the inner wall of the hole and the second side 5 (the inner wall of the clamping groove 11), thereby further improving the waterproof effect. At the same time, the elastic sealing ring has the function of expansion, which reduces the abnormal sound of the waterproof cover plate on the hole.
[0034] The above-mentioned is only the embodiment of the utility model, and the well-known specific technical solutions and / or characteristics in the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the utility model, a number of modifications and improvements can be made, which should also be considered as the protection scope of the utility model, and these will not affect the effect and practicality of the utility model. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
