[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.
[0022] Figure 1 It is the overall structure schematic view of the vehicle pollution discharge protection device provided by the embodiments of the utility model; Figure 2 It is the structure schematic view of the pollution discharge pipe of the vehicle pollution discharge protection device provided by the embodiments of the utility model; Figure 3 It is the structure schematic view of the overall structure of the vehicle pollution discharge protection device in another view provided by the embodiments of the utility model; Figure 4 It is the structure schematic view of the protection cover and the elastic clamping part of the vehicle pollution discharge protection device provided by the embodiments of the utility model.
[0023] As shown in Figures 1 to 4 The one end of the pollution discharge pipe 1 is connected to the pollution discharge system of the vehicle body through the mounting section 14, and the other end is provided with a pollution discharge port 11 for discharging the dirt stored in the pollution discharge system in the vehicle. The vehicle pollution discharge protection device provided by the embodiments of the utility model is used for protecting the above-mentioned pollution discharge port 11 during the driving of the vehicle. The protection device comprises a protection cover 2 detachably mounted on the pollution discharge pipe 1. The protection cover 2 has a protection surface 21. When the protection cover 2 is mounted on the pollution discharge pipe 1, the protection surface 21 can cover the pollution discharge port 11 of the pollution discharge pipe 1.
[0024] By arranging the protection cover 2 on the pollution discharge pipe 1, the protection cover 2 can prevent the external rain and snow or other foreign matters from entering the pollution discharge port 11 to cause blockage and other adverse conditions, so that the pollution discharge cannot be carried out smoothly when parking. When parking, the protection cover 2 is removed, and then the pollution discharge can be carried out.
[0025] When the vehicle drives in some high-cold areas, if it encounters rainy and snowy weather, the connection part of the protection cover 2 and the pollution discharge pipe 1 is covered with snow. The protection cover 2 is inevitably frozen with the pollution discharge pipe 1. At this time, if the protection cover 2 is taken off from the pollution discharge pipe 1 by the conventional way when parking and discharging, the ice needs to be melted by heating or other ways, which needs to consume a large amount of time. The parking time of the vehicle is usually only a few minutes or tens of minutes, which is not enough to carry out the above-mentioned operation.
[0026] The protective device provided by the embodiment of the utility model, the protective cover 2 is made of brittle material, when the protective cover 2 is frozen with the blowdown pipe 1, the protective cover 2 can be directly broken, the blowdown port 11 is exposed and can be connected with external blowdown equipment to smoothly blowdown, after blowdown, a new protective cover 2 can be installed on the blowdown pipe 1 to protect the blowdown port 11 in the next journey. Through the arrangement, the time required for blowdown can be greatly saved, and the blowdown system in the vehicle can be ensured to be smoothly operated all the time.
[0027] The protective cover 2 and the blowdown pipe 1 can be connected by screw fastening or clamping, as long as the protective cover 2 and the blowdown pipe 1 can be quickly connected and disconnected.
[0028] The brittle material of the protective cover 2 can be glass, ceramic or brittle plastic, and preferably plastic, which is not only low in cost, but also can be collected and reshaped after being broken, thereby avoiding waste and being particularly suitable for the vehicle section requiring frequent breakage and installation of the protective cover 2.
[0029] In addition, the protective cover 2 can be made of materials having good mechanical properties at normal temperature and brittleness at low temperature, such as polypropylene, polyethylene, polystyrene and polyvinyl chloride, so that the protective cover 2 and the blowdown pipe 1 will not be frozen when the vehicle travels in a high temperature area, and the protective cover 2 can have flexibility and will not be damaged when being detached from the blowdown pipe 1, and the protective cover 2 will be more brittle when the vehicle travels in a low temperature area, so that the protective cover 2 can be broken when frozen, which is more convenient and practical.
[0030] As shown in Figure 1 , Figure 3 and Figure 4 shown, the vehicle blowdown protective device provided by the embodiment of the utility model further comprises an elastic clamping part 3, the elastic clamping part 3 is used for detachably installing the protective cover 2 on the blowdown pipe 1, the first end of the elastic clamping part 3 is connected to the protective cover 2, and the second end of the elastic clamping part 3 can be clamped on the blowdown pipe 1 through elastic deformation, so that the protective cover 2 can be conveniently installed and removed on the blowdown pipe 1, and further convenience is provided for blowdown operation.
[0031] As shown in Figures 1 to 4 , in one preferred embodiment, the blowdown pipe 1 has a limiting section 12 and a clamping section 13 arranged along a first direction from the end face of the blowdown port 11, the first direction is the direction of the vehicle from the blowdown port 11 along the axial direction of the blowdown pipe 1, and Figure 3The first direction is a left direction, and the diameter of the clamping section 13 is smaller than the diameter of the limiting section. The second end of the elastic clamping piece 3 is provided with a deformation section 31 matched with the clamping section 13. When the deformation section 31 is matched with the clamping section 13, the limiting section 12 can limit the movement of the deformation section 31 in the opposite direction of the first direction, Figure 3 The first direction is a left direction, and the diameter of the clamping section 13 is smaller than the diameter of the limiting section. The second end of the elastic clamping piece 3 is provided with a deformation section 31 matched with the clamping section 13. When the deformation section 31 is matched with the clamping section 13, the limiting section 12 can limit the movement of the deformation section 31 in the opposite direction of the first direction,
[0032] In Figure 3 In the embodiment shown in the figure, the clamping section 13 is a circular annular groove formed by inwardly recessing the cylindrical end face of the limiting section 12. The cross section of the circular annulus is semicircular. The deformation section 31 is a semicircular structure matched with the shape of the clamping section 13 in the normal state. When the elastic clamping piece 3 is installed on the blowdown pipe 1, the deformation section 31 can be elastically deformed to expand its size and pass the limiting section 12. Then, the deformation section 31 is reset under the action of the internal elastic force and clamped in the clamping section 13. Similarly, when the elastic clamping piece 3 is removed, the deformation section 31 is elastically deformed again by pulling the protective cover 2 to pass the limiting section 12. Then, the elastic clamping piece 3 and the protective cover 2 can be removed from the blowdown pipe 1, which is more convenient for disassembling and assembling the protective cover 2.
[0033] It should be noted that, in Figure 3 In the embodiment shown in the figure, the clamping section 13 and the deformation section 31 are both arc-shaped. In some other embodiments, the clamping section 13 and the deformation section 31 can also have other shapes and matching modes, as long as the limiting section 12 can limit the deformation section 31 when the clamping section 13 is matched with the deformation section 31. In addition, in Figures 1 to 4 In the embodiment shown in the figure, the elastic clamping piece 3 is a metal elastic sheet, and there are four of them circumferentially spaced apart on the protective cover 2. In some other embodiments, the elastic clamping piece 3 can be of other materials, structures and quantities, as long as it can be clamped and connected with the blowdown port 1. Here, no further description is given.
[0034] In one preferred embodiment, the first end of the elastic clamping piece 3 is connected with the protective cover 2 by a screw, and the elastic clamping piece 3 has good mechanical strength. In this way, after the protective cover 2 is broken and removed, the elastic clamping piece 3 installed thereon can be further removed and recycled for reuse, avoiding waste.
[0035] In one preferred embodiment, a sealing structure is provided between the protective cover 2 and the blowdown pipe 1, which can improve the protection effect of the blowdown port 11 and prevent foreign matters from entering the blowdown port 11.
[0036] As Figure 4As shown, in one of the preferred embodiments, the protective cover 2 is further provided with a limiting surface 22, which is an annular structure formed by extending the circumferential edge of the protective surface 21 in the axial direction, the limiting surface 22 can be sleeved on the drain pipe 1, the limiting surface 22 is detachably connected with the protective surface 21, the sealing structure is arranged between the limiting surface 22 and the drain pipe 1, and the first end of the elastic clamping piece 3 is also connected to the limiting surface 22.
[0037] Through the above arrangement, when the protective cover 2 is broken, only the protective surface 21 covering the drain port 11 can be damaged, and the limiting surface 22, the sealing structure and the elastic clamping piece 3 sleeved on the drain pipe 1 are reserved, a new protective surface 21 can be installed on the limiting surface 22 after the drain is completed, waste can be avoided, and practicality is improved. The brittleness of the limiting surface 22 can be further set to be weaker than that of the protective surface 21, so that the protective surface 21 is more easily damaged than the limiting surface 22, and the protective surface 21 can remain intact when the protective surface 21 is damaged.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and they should be covered in the scope of the claims of the present application.
