Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile interior decoration, in particular to a defrosting air duct sealing sleeve and an interior decoration plate. Background Art
[0002] At present, in order to improve the defrosting and defogging function of the triangular area of the side window glass of a vehicle door, a side window glass defrosting and defogging structure is arranged on the inner side of the vehicle door, including an air inlet and an air outlet, the air inlet is arranged on the vehicle door interior panel, the air outlet is arranged near the vehicle window, the air duct is inserted into the air inlet to be connected with the air inlet, the cold air enters the air inlet through the air duct, and flows out from the air outlet, thereby blowing on the side windows of the vehicle door, thereby realizing the defrosting and defrosting of the vehicle windows and improving the defrosting and defogging function. For example, a utility model patent with Chinese patent announcement number CN214112493U discloses a side defrosting ventilation structure and a vehicle installed on a vehicle door interior panel.
[0003] In order to improve the aesthetics of the air inlet, improve the sealing between the air inlet and the air duct, avoid leakage of cold air from the gap between the air inlet and the air duct, and also avoid entry of external gas from the gap between the air inlet and the air duct, a defrost air duct sealing sleeve is installed on the air inlet.
[0004] The assembly method of the defrost duct sealing sleeve and the air inlet is as follows: a card slot is provided on the inner wall of the air inlet, a card connection rib is provided on the outer wall of the defrost duct sealing sleeve, and the defrost duct sealing sleeve is installed on the air inlet, and the card slot is clamped by the card connection rib, thereby realizing the clamping connection between the defrost duct sealing sleeve and the air inlet. However, in the process of installing the defrost duct sealing sleeve on the air inlet, the installer has a large amount of installation every day and the installation speed is fast. Since the defrost duct sealing sleeve is round and the appearance of the defrost duct sealing sleeve at different angles is the same, it is easy to make mistakes in the installation direction, that is, when the defrost duct sealing sleeve is inserted into the air inlet, the card connection rib is not opposite to the card slot, and the card connection rib is not clamped in the card slot. If the installer does not find it, the defrost duct sealing sleeve will be relatively loose at the air inlet, and abnormal noise will occur or the defrost duct sealing sleeve will fall off when the car is used later. Utility Model Content
[0005] The utility model aims to provide a defrosting air duct sealing sleeve and an interior decoration plate, so as to solve the problem that the defrosting air duct sealing sleeve is not easily found when it is installed in the wrong direction on the air inlet.
[0006] To achieve the above-mentioned purpose, the utility model adopts the following basic technical scheme: a defrost duct sealing sleeve, comprising an insertion portion and an outward-turned portion, the outward-turned portion is fixedly connected to the end of the insertion portion, a plurality of clamping ribs are provided on the insertion portion, and limiting ribs are also fixedly connected to the outer side wall of the insertion portion.
[0007] In addition, the present application also discloses another basic technical solution: an interior panel, including an air inlet, the inner wall of the air inlet is provided with a slot for cooperating with the snap-in ribs on the defrost air duct sealing sleeve, and the inner wall of the air inlet is also provided with a slot for cooperating with the limiting ribs of the defrost air duct sealing sleeve.
[0008] The principle and advantage of the above scheme of the present application are: the defrost duct sealing sleeve is used to be installed on the air inlet of the interior trim panel. During the installation process, the insertion part is inserted into the air inlet, and the outward-turned part is located on the outside of the air inlet. The outward-turned part blocks the gap between the air inlet and the insertion part, thereby playing a role in aesthetics. The insertion part is inserted into the air inlet and is clamped in the clamping groove through the clamping rib, thereby realizing the axial direction limitation of the defrost duct sealing sleeve, and the defrost duct sealing sleeve is not easy to be separated from the air inlet.
[0009] During the installation process, if the installation position of the defrost duct sealing sleeve is correct, the limiting rib will be opposite to the slot. When the defrost duct sealing sleeve is pushed into the air inlet, due to the existence of the slot, the inner wall of the air inlet will not hinder the limiting rib, and the limiting rib can enter the slot. If the installation position of the defrost duct sealing sleeve is incorrect, when the defrost duct sealing sleeve is pushed into the air inlet, the limiting rib and the slot are not aligned, the limiting rib and the slot are in a staggered state, and the inner wall of the air inlet will hinder the limiting rib, making it difficult for the defrost duct sealing sleeve to be inserted into the air inlet. In this way, the installer will find that the installation position of the defrost duct sealing sleeve is incorrect. The subsequent installer will adjust the position of the defrost duct sealing sleeve by rotating it (the relative position of the limiting rib and the slot), and then correctly install the defrost duct sealing sleeve into the air inlet to ensure that the snap-in rib and the slot can snap into place normally.
[0010] Preferably, as an improvement, the distance between the end surface of the limiting rib and the outer side wall of the insertion portion is 2-4 mm.
[0011] After the limiting ribs are set, although it can prevent the defrost duct sealing sleeve from being installed incorrectly, the inventor, in the initial design, made the distance between the end face of the limiting rib and the outer wall of the insertion portion relatively large, that is, the limiting rib is relatively high and the limiting rib protrudes to a large extent. In this way, during the process of inserting the defrost duct sealing sleeve into the air inlet, even if the slot and the limiting rib are relative, due to the high limiting rib and the large protrusion, the end face of the limiting rib will contact and rub against the inner wall of the slot, and the two have a certain interference force, resulting in deformation of the limiting rib after assembly, and more laborious during assembly. For this reason, the inventor reduced the height of the limiting rib, and it is more appropriate to limit the height of the limiting rib to 2-4mm, which can avoid the end face of the limiting rib from having a strong interference with the inner wall of the slot, facilitate the assembly of the defrost duct sealing sleeve, and reduce the deformation of the limiting rib. At the same time, it also avoids the misjudgment of assembly errors caused by assembly difficulties.
[0012] Preferably, as an improvement, the insertion portion is fixedly connected with a positioning column. At the same time, the inner wall of the air inlet is provided with a table, and the table is provided with a positioning hole for cooperating with the positioning column.
[0013] Thus, when the defrost duct sealing sleeve is installed in the air inlet, if the installation position is correct, the positioning column is opposite to the positioning hole and the positioning column will be inserted into the positioning hole. If the defrost duct sealing sleeve is installed in an incorrect position, the positioning column is staggered with the positioning hole and the positioning column will not be inserted into the positioning hole. The positioning column will abut against the table, thereby preventing the defrost duct sealing sleeve from being inserted into the air inlet, which is conducive to timely discovering that the defrost duct sealing sleeve is installed in an incorrect position, thereby avoiding incorrect installation of the defrost duct sealing sleeve.
[0014] The inventor designed the positioning column to further prevent the defrost duct sealing sleeve from being incorrectly installed because it is considered that after the height of the limiting rib is reduced, during the installation process, even if the limiting rib is not aligned with the slot, the interference between the limiting rib and the inner wall of the air inlet is reduced, and the ability of the limiting rib to prevent incorrect installation is reduced. The installation worker can overcome the interference between the limiting rib and the inner wall of the air inlet with a little force, thereby incorrectly installing the defrost duct sealing sleeve into the air inlet. Therefore, the positioning column is provided to further prevent the defrost duct sealing sleeve from being incorrectly installed.
[0015] Preferably, as an improvement, the end of the positioning column extends to the outside of the end of the insertion portion.
[0016] Therefore, the length of the positioning column exceeds the end face of the insertion part. When the assembly direction is inconsistent, the positioning column will prop up and tilt the defrost duct sealing sleeve, so that the installer can easily find the wrong installation direction and make timely adjustments.
[0017] Preferably, as an improvement, the end of the positioning column is chamfered to form a tip.
[0018] Therefore, the setting of the tip has a guiding function, making it easier for the positioning post to be inserted into the positioning hole.
[0019] Preferably, as an improvement, the diameter of the bottom of the positioning post is at least 2 mm, and the diameter of the tip of the positioning post is at least 1.5 mm.
[0020] Therefore, choosing a positioning column with this parameter can avoid the problem of the positioning column being too thin and easily breaking due to installation errors.
[0021] Preferably, as an improvement, the number of the clamping ribs is three, and the widths of any two of the clamping ribs are different.
[0022] Therefore, the width of the clamping ribs (here the width direction is the circumferential direction of the insertion part) is set differently. Compared with the case where the width of the clamping ribs is the same, the installers will distinguish the clamping ribs during installation, which plays a fool-proof role and thus pays more attention to the correctness of the installation position of the sealing sleeve, which is helpful to assist in solving the problem of avoiding incorrect assembly of the defrost duct sealing sleeve.
[0023] Preferably, as an improvement, a plurality of support sheets are provided inside the insertion portion, and both ends of the support sheets are fixedly connected to the inner wall of the insertion portion.
[0024] Thus, the support sheet supports the insertion part to prevent the insertion part from being deformed or directly deformed after being blown by hot air or cold air for a long time on the sealing sleeve, which is beneficial to ensure that the insertion part maintains its original shape and ensures the sealing effect.

[0032] The following is further described in detail through specific implementation methods:
[0033] The figure marks in the drawings of the specification include: interior trim panel 1, defrost duct sealing sleeve 2, air inlet 3, support plate 4, limiting rib 5, inclined surface 6, snap-in rib 7, clamping block 8, outward-turned portion 9, insertion portion 10, slot 11, clamping groove 12, support surface 13, positioning column 14, and table top 15.
[0034] Example 1
[0035] Basically as attached Figure 1-Figure 6As shown: This embodiment discloses a defrost duct sealing sleeve 2, including an insertion portion 10 and an outward-turned portion 9, one end of the insertion portion 10 and the outward-turned portion 9 are integrally formed, and the entire structure of the defrost duct sealing sleeve 2 in this embodiment is injection molded. The shape of the insertion portion 10 is cylindrical, and the shape of the outward-turned portion 9 is annular. A plurality of support sheets 4 are provided inside the insertion portion 10, and both ends of the support sheets 4 are integrally formed and connected to the inner wall of the insertion portion 10. The support sheets 4 can strengthen the structure of the insertion portion 10, prevent the insertion portion 10 from being deformed due to long-term contact with cold air or hot air, and help the defrost duct sealing sleeve 2 maintain its shape. There is a gap between adjacent support sheets 4, so as not to affect the passage of gas through the defrost duct sealing sleeve 2.
[0036] Combination Figure 6 As shown, a plurality of clamping ribs 7 are integrally formed on the insertion portion 10 (the clamping ribs 7 are part of the insertion portion 10, the left and right ends of the clamping ribs 7 are provided with clearance grooves, the bottom of the clamping ribs 7 and the support surface are integrally fixed, and the clamping ribs 7 can undergo elastic bending and deformation). The number of the clamping ribs 7 in this embodiment is three, and a clamping block 8 is integrally formed on the outer wall of the three clamping ribs 7, and a guide slope is provided at the bottom of the clamping block. A limiting rib 5 is also integrally formed on the outer wall of the insertion portion 10. The distance between the end face of the limiting rib 5 and the outer wall of the insertion portion 10 (the height of the limiting rib 5 in the protruding direction) is 4-6mm, specifically 5mm, and a slope 6 is provided at the bottom of the limiting rib 5.
[0037] In addition, the present embodiment also discloses Figure 3 The interior panel 1 shown includes an air inlet 3, combined with Figure 5 and Figure 4 As shown, a table 15 is provided on the inner wall of the air inlet 3, and three card slots 12 are provided on the inner wall of the air inlet 3 for cooperating with the card connection ribs 7 on the defrost air duct sealing sleeve 2. Figure 5 The middle card slot 12 is located below the table 15, and the inner wall of the air inlet 3 is also provided with a slot 11 for cooperating with the limiting rib 5 of the defrosting air duct sealing sleeve 2, and the slot 11 passes through the table 15, so that Figure 5 The top and bottom ends of the middle slot 11 are connected.
[0038] The specific implementation process is as follows: insert the defrost duct sealing sleeve 2 into the air inlet 3, insert the insertion part 10 into the air inlet 3, and the outward turning part 9 is located on the outside of the interior trim panel 1. After the defrost duct sealing sleeve 2 is assembled in place, the insertion part 10 enters the air inlet 3, and then the defrost duct sealing sleeve 2 is assembled into the air inlet 3. Figure 4 As shown, the block 8 of the clamping rib 7 is clamped in the clamping groove 12, and the block 8 and the bottom of the clamping groove 12 are against each other, so that the defrost duct sealing sleeve 2 cannot be pulled out from the air inlet 3, so that the defrost duct sealing sleeve 2 is stably located in the air inlet 3. This section of technology is consistent with the operation of the prior art.
[0039] The innovation lies in that, during the installation process, if the installation position of the defrost duct sealing sleeve 2 is correct, the limiting rib 5 will be opposite to the slot 11. When the defrost duct sealing sleeve 2 is pushed into the air inlet 3, due to the existence of the slot 11, the inner wall of the air inlet 3 (specifically the table 15) will not hinder the limiting rib 5. Figure 4 As shown, the limiting rib 5 can enter the slot 11, so that the defrost air duct sealing sleeve 2 can be smoothly inserted into the air inlet 3. At this time, the corresponding clamping rib 7 is clamped in the corresponding clamping groove 12 after the installation is completed.
[0040] If the installation position of the defrost duct sealing sleeve 2 is incorrect, then in the process of pushing the defrost duct sealing sleeve 2 into the air inlet 3, the limiting rib 5 and the slot 11 are not aligned, and the limiting rib 5 and the slot 11 are in a staggered state. The inner wall of the air inlet 3 (specifically the table top 15) will hinder and interfere with the limiting rib 5, making it difficult for the defrost duct sealing sleeve 2 to be inserted into the air inlet 3. In this way, the installer will find that the installation position of the defrost duct sealing sleeve 2 is incorrect, and will adjust the position of the defrost duct sealing sleeve 2 by rotating it (so that the limiting rib 5 and the slot 11 are in relative positions), and then correctly install the defrost duct sealing sleeve 2 into the air inlet 3 to ensure that the snap-in rib 7 and the slot 12 can snap into place normally.
[0041] Example 2
[0042] After the limiting rib 5 is set in Example 1, although it can prevent the defrost duct sealing sleeve 2 from being installed incorrectly, the distance between the end face of the limiting rib 5 and the outer wall of the insertion portion 10 is large, that is, the limiting rib 5 is high, and the limiting rib 5 protrudes to a large extent. In this way, when the defrost duct sealing sleeve 2 is inserted into the air inlet 3, even if the slot 11 and the limiting rib 5 are opposite, due to the high limiting rib 5, the end face of the limiting rib 5 will hit the inner wall of the slot 11, thereby contacting and rubbing against each other, with a certain interference force, causing the limiting rib 5 to deform after assembly. For this reason, the inventor reduces the height of the limiting rib 5 by 2mm on the basis of Example 1, so that it is more appropriate to limit the height of the limiting rib 5 to 2-4mm, specifically 3mm, so as to avoid the end face of the limiting rib 5 from having a strong interference with the inner wall of the slot 11, which is conducive to the assembly of the defrost duct sealing sleeve 2 and reduces the deformation of the limiting rib 5.
[0043] Example 3
[0044] After the height of the limiting rib 5 in Example 2 is reduced, the protrusion of the limiting rib 5 is reduced, and the function of the limiting rib 5 to prevent wrong installation will be reduced. That is, even if the limiting rib 5 is not directly opposite to the slot 11, the mutual interference ability of the limiting rib 5 and the table 15 of the air inlet 3 is reduced, and the ability of the limiting rib 5 to prevent wrong installation will be reduced. In this way, when the limiting rib 5 is not directly opposite to the slot 11, the installer can overcome the interference between the limiting rib 5 and the table 15 of the air inlet 3 with a little force, and the table 15 will not cause obstruction to the limiting rib 5, so that even if the defrost duct sealing sleeve 2 is installed in the wrong position, the defrost duct sealing sleeve 2 will be mistakenly installed in the air inlet 3.
[0045] Therefore, this embodiment is further improved on the basis of embodiment 2, Figure 7 As shown, a support surface 13 is provided on the insertion portion 10, and a positioning column 14 is integrally formed on the support surface 13. The positioning column 14 is located on the outer side surface of the insertion portion 10, and the end of the positioning column 14 extends to the outside of the end of the insertion portion 10, that is, the length of the positioning column 14 is greater than the distance between the support surface 13 and the end surface of the insertion portion 10. The end of the positioning column 14 is chamfered to form a tip. The bottom diameter of the positioning column 14 is at least 2 mm, and the diameter of the tip of the positioning column 14 is at least 1.5 mm. At the same time, a positioning hole (not shown in the figure) that cooperates with the positioning column 14 is provided on the table surface 15 of the inner wall of the air inlet 3.
[0046] In this way, the defrost duct sealing sleeve 2 is installed in the air inlet 3. If the installation position is correct, the positioning column 14 is opposite to the positioning hole, the positioning column 14 will be inserted into the positioning hole, and the positioning column 14 will not abut against the table 15 to affect the installation of the defrost duct sealing sleeve 2 in the air inlet 3. If the installation position of the defrost duct sealing sleeve 2 is incorrect, the positioning column 14 is staggered with the positioning hole, the positioning column 14 will not be inserted into the positioning hole, and during the installation of the defrost duct sealing sleeve 2 in the air inlet 3, the positioning column 14 abuts against the table 15, so that the defrost duct sealing sleeve 2 has not been installed in the air inlet 3, and it tilts and protrudes under the action of the positioning column 14, so that it cannot be installed in the air inlet 3. The installer can find it in time, which is conducive to avoiding the wrong installation of the defrost duct sealing sleeve 2 and solving the problem of the reduced anti-wrong installation ability after the height of the limiting rib 5 is reduced by 2mm.
[0047] Example 4
[0048] This embodiment is further defined on the basis of the above-mentioned embodiments 1-3. The widths of the three clamping ribs 7 are all different, and the widths of the three clamping grooves 12 are also different. However, the corresponding clamping grooves 12 match the sizes of the corresponding clamping ribs 7 when installed correctly. This avoids the situation where the three clamping ribs 7 are all the same size, causing the installers to pay less attention to the orientation. When the widths of the three clamping ribs 7 are different, the installers will distinguish between the clamping ribs 7 of different widths during installation and will pay more attention to the installation direction, which is conducive to improving the assembly accuracy.
[0049] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
