Description

Technical Field

[0001] The present application relates to the field of vehicles, and particularly to a sealing plug and a vehicle. Background Art

[0002] During the production process of vehicles, various functional holes are opened on the vehicle body. Among them, one type of hole is used to drain the painting electrocoating liquid, and these openings must be sealed before the vehicle rolls off the production line. Otherwise, problems such as water leakage, noise, and vibration will occur during the use of the vehicle, thus affecting the overall sealing performance or NVH (Noise, Vibration, Harshness) performance of the vehicle.

[0003] In the field of vehicle body sealing, plugs are the most widely used sealing parts. According to the usage scenarios, there are two different types of plugs, namely ordinary plugs for final assembly and hot-melt plugs for the vehicle body and painting workshops. Among them, in order to seal the electrocoating leakage holes in the vehicle body cavity, hot-melt plugs are usually used. This type of plug has a simple structure, and its working principle is to melt the hot-melt adhesive during baking and bond it to the vehicle body to achieve the purpose of plugging the functional holes of the vehicle body.

[0004] However, during the pretreatment and electrocoating processes of vehicles, after the hot-melt plug is assembled, the upper and lower lips are in a clamped state, and the bath liquid cannot be drained completely in a short time, resulting in residual bath liquid and contaminating subsequent processes. Specifically, the residual electrocoating liquid will also cause electrocoating flow marks during subsequent baking, which will greatly affect the appearance quality and subsequent anti-corrosion performance. In addition, the incomplete drainage of water on the vehicle body will also increase the moisture in the electrocoating oven, causing other quality problems and oven emission problems. In addition, the existing hot-melt plugs are generally flat in shape, which is inconvenient for workers to pick up during installation, and it is not easy to operate during both installation and disassembly, easily leading to situations such as improper installation. Summary of the Utility Model

[0005] The present application provides a sealing plug and a vehicle to solve some or all of the deficiencies in the related art.

[0006] The present application provides a sealing plug, including: a plug body, a liquid leakage hole, a sealing lip, a side wall, and a receiving cavity. The plug body includes an installation side and a plugging side that are oppositely arranged. The liquid leakage hole is provided in the plug body and communicates the installation side and the plugging side. The sealing lip surrounds the periphery of the plug body. The side wall is provided on the installation side and is connected to the plug body. Among them, the side wall surrounds and forms the receiving cavity of the sealing plug.

[0010] Optionally, the holding member further includes a protruding portion. The protruding portion is disposed on an outer surface of the holding member.

[0011] Optionally, the protruding portion surrounds the outer surface of the holding member, and in a direction from the plugging side to the mounting side, the protruding portion is inclined in a direction gradually away from the holding member.

[0012] Optionally, the plug body further includes a diversion groove disposed on the plugging side. The diversion groove communicates with the liquid leakage hole. Wherein, in a direction from the mounting side to the plugging side, an inner diameter of the diversion groove gradually increases.

[0013] Optionally, the sealing lip includes an upper rubber plug and a lower rubber plug. Wherein, one side of the lower rubber plug is connected to the plug body, and the other side extends in a direction away from the liquid leakage hole and forms a second extension portion. One side of the upper rubber plug is connected to the second extension portion, and the other side extends in a direction away from the liquid leakage hole.

[0014] Optionally, the upper rubber plug includes a mounting portion and a first extension portion.

The first extension portion is disposed opposite to the second extension portion.

[0015] Optionally, the mounting portion, the plug body, and the side wall surround to form a spacer groove of the sealing plug cover.

[0016] Optionally, the sealing plug cover is integrally formed; and / or, the sealing plug cover is made of a thermoplastic elastomer material.

[0018] The technical solution provided by the embodiment of the present application may include the following beneficial effects:

[0019] As can be seen from the above embodiments, the sealing plug of the present application is provided with a liquid leakage hole to communicate the installation side and the plugging side of the plug body, thereby facilitating the flow and discharge of liquid. At the same time, the sealing plug forms a receiving cavity for placing hot melt adhesive by arranging a side wall. In processes such as pre-treatment and electrophoresis, the liquid can flow out smoothly through the liquid leakage hole. In the subsequent baking process, after the ambient temperature rises, the annular hot melt adhesive melts and plugs the liquid leakage hole, thereby ensuring the sealing performance of the sealing plug. It can be seen that the sealing plug of the present application can achieve different effects in different production processes, which not only ensures the drainage during production but also avoids subsequent problems such as water leakage and noise caused by poor sealing of the holes. In addition, the structure of the sealing plug is simple, easy to produce and install, and it plugs the liquid leakage hole by melting the hot melt adhesive without manual sealing. It can be seen that the structural design of the sealing plug effectively improves the convenience and practicality during its production, installation and use, and ensures its liquid leakage efficiency and subsequent sealing effect.

Detailed implementation manner

[0029] Here, the technical solutions in the embodiments (or "implementation manners") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement conditions between components in a specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0031] As Figures 1 to 4 shown, the present application provides a sealing plug cover 1, including: a plug cover body 11, a liquid leakage hole 12, a sealing lip 13, a side wall 14, and an accommodating cavity 15. The plug cover body 11 includes an installation side 11a and a plugging side 11b that are oppositely arranged. The liquid leakage hole 12 is provided in the plug cover body 11 and communicates the installation side 11a and the plugging side 11b. The sealing lip 13 surrounds the circumferential side of the plug cover body 11. The side wall 14 is provided on the installation side 11a and is connected to the plug cover body 11. Among them, the side wall 14 surrounds and forms the accommodating cavity 15 of the sealing plug cover 1. The accommodating cavity 15 communicates with the liquid leakage hole 12 and is used for placing the hot melt adhesive 2.

[0032] The sealing plug cover 1 of the present application is provided with a liquid leakage hole 12 to communicate the installation side 11a and the plugging side 11b of the plug cover body 11, thus facilitating the flow and discharge of liquid. At the same time, the sealing plug cover 1 is provided with a side wall 14 to enclose a receiving cavity 15 for placing the hot melt adhesive 2. In the pre-treatment and electrophoresis processes, the liquid can flow out smoothly through the liquid leakage hole 12. In the subsequent baking process, after the ambient temperature rises, the annular hot melt adhesive 2 melts and plugs the liquid leakage hole 12, thus ensuring the sealing performance of the sealing plug cover 1. It can be seen that the sealing plug cover 1 of the present application can achieve different effects in different production processes, which not only ensures the drainage during the production process, but also avoids subsequent problems such as water leakage and noise caused by poor sealing of the holes. In addition, the structure of the sealing plug cover 1 is simple, easy to produce and install, and its plugging of the liquid leakage hole 12 is realized by melting the hot melt adhesive 2 without manual sealing. It can be seen that the structural design of the sealing plug cover 1 effectively improves the convenience and practicality in its production, installation and use processes, and ensures its liquid leakage efficiency and subsequent sealing effect.

[0033] It should be noted that the installation side 11a and the plugging side 11b defined in the present application are only orientation definitions and not the specific surfaces of the sealing plug cover 1. The liquid leakage hole 12 communicates the installation side 11a and the plugging side 11b, which means that before the vehicle enters the baking process, the installation side 11a and the plugging side 11b are always connected. That is to say, after the sealing plug cover 1 of the present application places the hot melt adhesive 2 into the receiving cavity 15, the installation side 11a and the plugging side 11b are still in a connected state. Therefore, the specific structure of the hot melt adhesive 2 can be set according to the actual installation and use conditions. For example: the structure of the hot melt adhesive 2 can be set as the Figure 2 shown annular structure and adhered to the inner wall of the side wall 14, so as to also reserve a hole corresponding to the liquid leakage hole 12 at the center position of the hot melt adhesive 2 to ensure the connection of the spaces on both sides of the sealing plug cover 1. Of course, any hole structure can also be set on the surface of the hot melt adhesive 2 to connect the spaces on both sides of the sealing plug cover 1 and so on. Therefore, the present application does not limit this.

[0034] In contrast, referring to the Figure 5 existing plug cover design shown, the existing plug cover is not provided with holes for liquid leakage. Therefore, after the plug cover is installed, the liquid remaining in the closed cavity of the vehicle body can only flow out through some other gaps or holes, which greatly limits the liquid leakage efficiency and may cause the liquid to remain in the cavity, thus affecting the subsequent processes.

[0035] In addition, the present application also provides a vehicle, including a vehicle body, a body hole and the sealing plug cover 1 described above. Among them, the body hole is opened on the vehicle body. The sealing plug cover 1 is installed in the body hole.

[0036] The provision of the sealing plug 1 enables the body holes of the vehicle body to still maintain excellent drainage performance, and can quickly drain the liquid remaining in the cavity of the vehicle body during the production process, avoiding the situation that the subsequent production process is affected by the liquid residue. At the same time, the provision of the sealing plug 1 also enables the vehicle to seal the body holes through the hot melt adhesive 2 for both the accommodating cavity 15 and the liquid leakage hole 12 during the baking process, thereby ensuring the sealing performance of the body holes during the subsequent processing and use of the vehicle, and avoiding problems such as water leakage, noise, and vibration caused by the unsealed body holes, which affect the use performance of the vehicle and the driving experience of the user, etc.

[0037] In the actual production process, since these body holes are provided in the closed cavity of the vehicle body, the installation of the sealing plug 1 needs to be completed in the workshop. Thus, the operator can install the sealing plug 1 in each body hole of the vehicle body before the vehicle body enters the painting workshop. Specifically, the operator can align the plugging side 11b of the sealing plug 1 with the body hole and press the sealing plug 1 along the first direction X on the installation side 11a. And in an alternative embodiment, the sealing lip 13 includes an upper rubber plug 131 and a lower rubber plug 132. Therefore, the upper rubber plug 131 and the lower rubber plug 132 will clamp the sheet metal part of the vehicle body, thereby completing the installation of the sealing plug 1. It can be seen that the installation process of the sealing plug 1 is very simple and efficient, ensuring the convenience and quality of the production process.

[0038] During the painting process, there may be a situation where liquid remains in the cavity of the vehicle body. For example, during the pretreatment and electrophoresis processes of the vehicle body, tank liquid, electrophoresis liquid, etc. may remain in the cavity of the vehicle body. At this time, due to the provision of the circulation holes, the remaining tank liquid and electrophoresis liquid can drain out through the circulation holes of the sealing plug 1 in a short time, thus avoiding the situation that the subsequent process is contaminated by the tank liquid residue, and also avoiding the situation that electrophoresis flow marks are generated during baking due to the remaining electrophoresis liquid, which in turn affects the overall appearance quality and anti-corrosion performance of the vehicle. It can be seen from this that the provision of the sealing plug 1 can better ensure the painting quality of the vehicle and the safety of the production process.

[0039] After the vehicle body enters the baking stage, the hot melt adhesive 2 is heated and melted, and seals part of the area of the accommodating cavity 15 and the circulation holes, thereby sealing the corresponding body holes, so that the operator does not need to re-plug these body holes, ensuring the smooth progress of the subsequent production process, and also guaranteeing the sealing effect and NVH performance of the whole vehicle.

[0040] In an alternative embodiment, combined with Figure 2 and Figure 4 it can be seen that the plug body 11 is disc-shaped. The liquid leakage hole 12 is opened at the center position of the plug body 11.

[0041] In the actual application process, since the body holes are generally round holes, the structural setting of the plug cover body 11 further improves the convenience of the mating connection between the sealing plug 1 and the body holes, and also improves the sealing performance between the sealing plug 1 and the sheet metal parts of the vehicle body. The setting of the liquid leakage hole 12 effectively promotes the efficiency of liquid flow during the liquid leakage process, ensures that the vehicle body can drain the liquid in the cavity more completely, and thus ensures the smooth progress of the subsequent production process. At the same time, as can be seen from the figure, the hot melt adhesive 2 of the present application is set in a ring shape and is arranged in the accommodation cavity 15. Therefore, the liquid leakage hole 12 is opened at the central position of the plug cover body 11, which also enables the hot melt adhesive 2 to more evenly seal the liquid leakage hole 12 after melting, ensuring the sealing effect of the sealing plug 1 and the subsequent sealing performance of the entire vehicle.

[0042] In an alternative embodiment, the sealing plug 1 further includes a holding member 16 connected to the plug cover body 11. The holding member 16 is arranged on the mounting side 11a and extends in a direction away from the sealing side 11b.

[0043] With the provision of the holding member 16 in the sealing plug 1 of the present application, an operator can install it by hand-holding the holding member 16, and during the installation process, only by holding the holding member 16 can the sealing plug 1 be pressed into the body hole in the first direction X. It can be seen that the provision of the holding member 16 not only improves the convenience during installation, but also enables the operator to more conveniently and clearly feel the installation position and state of the sealing plug 1 and make adaptive adjustments, thereby improving the convenience, accuracy during installation of the sealing plug 1 and the sealing effect after installation.

[0044] In an alternative embodiment, the holding member 16 is connected to the side wall 14 on the side away from the accommodation cavity 15. The structural setting of the holding member 16 of the sealing plug 1 improves the installation convenience of the sealing plug 1 while also avoiding the deformation of the plug cover body 11 caused by the operator's hand-holding the holding member 16, thereby affecting the sealing performance of the sealing plug 1 and other situations.

[0045] Of course, the specific structure of the holding member 16 can be adjusted and set accordingly according to the actual structure and installation requirements of the sealing plug 1. For example: the holding member 16 can be set as a plate shape, and during installation or disassembly, the operator can operate by pinching the plate-shaped holding member 16; or the holding member 16 can also be set as a rod shape, and such a structure can further facilitate the operator to pull; in addition, the holding member 16 can also be set as a shape similar to a handle, and the operator can use fingers to press or pull the handle for installation and disassembly, etc. Therefore, the present application does not limit this.

[0046] In an alternative embodiment, the holding member 16 further includes a protruding portion 161. The protruding portion 161 is arranged on the outer surface of the holding member 16.

[0047] The provision of the protrusion 161 can provide better lateral damping for the grip 16, such that when an operator holds the grip 16 for installation or disassembly work, situations such as the hand slipping off will not occur, further improving the convenience and safety during the picking up, installation of the sealing plug cover 1. Of course, the specific structure of the protrusion 161 can be set accordingly according to the actual working conditions and usage requirements. For example: multiple small bumps can be set as the protrusion 161, such a setting not only ensures the integration of the overall structure, but also improves the anti-slip effect of the grip 16; a columnar protrusion or multiple annular anti-slip edges and other structures can also be set as the protrusion 161 and so on. Therefore, this application does not limit this.

[0048] As Figure 1 and Figure 2 shown, in an alternative embodiment, the protrusion 161 is disposed around the outer surface of the grip 16, and in the direction from the plugging side 11b to the installation side 11a, the protrusion 161 is inclined in a direction gradually away from the grip 16.

[0049] The structural setting of the protrusion 161 in this application makes the grip 16 more adaptable to the force application direction of the operator during installation, thereby being able to further improve the convenience of the operator during installation and making the installation process of the sealing plug cover 1 more labor-saving.

[0050] As Figure 2 shown, in an alternative embodiment, the plug cover body 11 further includes a diversion groove 17 provided on the plugging side 11b. The diversion groove 17 is in communication with the liquid leakage hole 12. Wherein, in the direction from the installation side 11a to the plugging side 11b (i.e., the first direction X), the inner diameter of the diversion groove 17 gradually increases.

[0051] After the sealing plug cover 1 is installed in the vehicle body hole, the structural setting of the diversion groove 17 makes the plugging side 11b of the sealing plug cover 1 present a sunken diversion structure, and diverts the liquid in the cavity of the vehicle body through the diversion groove 17 to the circulation hole and discharges it. It can be seen that the setting of the diversion groove 17 effectively improves the drainage efficiency of the sealing plug cover 1 and ensures the smooth progress of the subsequent production process of the vehicle.

[0052] In an alternative embodiment, the sealing lip 13 includes a rubber plug upper lip 131 and a rubber plug lower lip 132. Wherein, one side of the rubber plug lower lip 132 is connected to the plug cover body 11, and the other side extends in a direction away from the liquid leakage hole 12 and forms a second extension portion 1321. One side of the rubber plug upper lip 131 is connected to the second extension portion 1321, and the other side extends in a direction away from the liquid leakage hole 12.

[0053] Refer to Figure 5It can be seen that in the structure of the existing plug cover 3, the upper lip 31 and the lower lip 32 are generally separately arranged, and a relatively wide gap is left between the upper lip 31 and the lower lip 32 for the sheet metal parts of the vehicle body to be inserted. Such a structural arrangement may cause the problem that the pressing force on the sheet metal parts by the plug cover 3 is insufficient. Therefore, in order to provide a greater pressing force, it is necessary to set a larger inclination angle for the upper lip 31 and the lower lip 32, and even it is necessary to set a hot melt adhesive 2 between the upper lip 31 and the lower lip 32 to further improve its sealing effect. However, the setting position of the hot melt adhesive 2 not only brings inconvenience to the production and installation of the plug cover 3, but also may cause it to be exposed above the upper lip 31 after melting, thus having a certain impact on the integrity and appearance of the vehicle. In the sealing plug cover 1 of the present application, the rubber plug upper lip 131 is directly connected to the second extension 1321 of the rubber plug lower lip 132, so that the structure of the rubber plug upper lip 131 is set based on the rubber plug lower lip 132. Therefore, their elastic deformations also restrict each other, and the gap between the rubber plug upper lip 131 and the rubber plug lower lip 132 is smaller, and the connection with the sheet metal parts is tighter. It can be seen that the structure of the sealing lip edge 13 is more ingenious, compact and integral, further ensuring that the connection between the sealing plug cover 1 and the vehicle body hole is tight and the sealing effect is better, and there is no need to additionally set a hot melt adhesive 2 or other materials at the connection to improve its sealing performance. Therefore, the use cost of the sealing plug cover 1 is also reduced.

[0054] As Figure 2 shown, in an optional embodiment, the rubber plug upper lip 131 includes a mounting portion 1311 and a first extension 1312. One side of the mounting portion 1311 is connected to the second extension 1321, and the other side is connected to the first extension 1312. The first extension 1312 is disposed opposite to the second extension 1321.

[0055] The upper lip 131 of the rubber plug is connected to the second extension 1321 of the lower lip 132 of the rubber plug through the installation part 1311, and is provided with a first extension 1312 corresponding to the second extension 1321. As can be seen from the accompanying drawings, the first extension 1312 and the second extension 1321 are arranged oppositely, which makes the surface area of the first extension 1312 and the second extension 1321 in contact with the sheet metal part larger after the sealing plug cover 1 is installed in the vehicle body hole. Therefore, the installed structure is tighter and more firm, and the sealing effect is also better. In addition, due to the setting of the installation part 1311, a certain distance and capacity are left between the upper lip 131 and the lower lip 132 of the rubber plug, so that the sealing plug cover 1 can be installed even if the thickness of the sheet metal part of the vehicle body is large. Of course, in some other embodiments, the gap size between the upper lip 131 and the lower lip 132 of the rubber plug can be adjusted accordingly according to specific structures, strengths and other requirements. For example, the gap size can be set larger to adapt to thicker sheet metal parts; of course, the gap size can also be set smaller to make the connection between the sealing lip 13 and the sheet metal part tighter, etc. Therefore, this application does not limit this.

[0056] In an alternative embodiment, the installation part 1311, the plug cover body 11 and the side wall 14 enclose to form a spacer groove 18 of the sealing plug cover 1.

[0057] During the actual installation process, after the operator installs the sealing plug cover 1 into the vehicle body hole, the sheet metal part presses against the outer surface of the installation part 1311 and deforms it, so as to rely on the self-elasticity of the upper lip 131 and the lower lip 132 of the rubber plug to ensure the tight connection between the sealing lip 13 and the sheet metal part, thereby improving the installation effect and sealing performance of the sealing plug cover 1. Refer to Figure 2 the structure shown in. A spacer groove 18 is formed between the installation part 1311 of the sealing plug cover 1 and the side wall 14. Therefore, when the operator presses the sealing plug cover 1 into the vehicle body hole, the spacer groove 18 provides a certain space margin for the deformation of the installation part 1311, ensuring the smooth installation of the sealing plug cover 1, and thus also ensuring the safety and production quality during the vehicle production process.

[0058] In an alternative embodiment, the sealing plug cover 1 is integrally formed to improve the convenience and safety during production and use. In addition, the production material of the sealing plug cover 1 can be correspondingly set according to the specific structure and requirements. For example, ethylene propylene diene monomer (EPDM) with relatively low price can be used, or thermoplastic polyester elastomer TPEE with better elasticity can be used, or thermoplastic polyurethanes (TPU) with higher strength can also be used, etc. Additionally, the hot melt adhesive 2 can be made of ethylene vinyl acetate copolymer material (EVA) or other materials. Therefore, the present application does not limit the materials used in the production of the plug body 11.

[0059] In an alternative embodiment, the plug body 11 and the sealing lip 13 of the present application are made of thermoplastic elastomer material (Thermo Plastic Elastomer, TPE), while the hot melt adhesive 2 is made of ethylene vinyl acetate copolymer material. Among them, the thermoplastic elastomer material has properties such as high elasticity, high strength, and high resilience. Its production and processing process is simple, the production efficiency is high, and the thermoplastic elastomer material has strong heat resistance and can withstand a high temperature of about 180 °C at most, while the melting temperature of the hot melt adhesive 2 is generally between 120 °C and 180 °C. It can be seen that using the thermoplastic elastomer material to make the plug body 11 and the sealing lip 13 can ensure that in the high-temperature environment during production, the hot melt adhesive 2 melts and seals the liquid leakage hole 12, while the plug body 11 and the sealing lip 13 will not be melted by the high temperature, ensuring the safety and sealing performance of the plug body 11.

[0060] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
