[0046] The advantage of this embodiment is that by using the cover 2 to enclose the outside of the snail-shaped horn 1, water flowing in from the gaps in the upper part of the vehicle body will not enter the connection between the plastic part 13 and the metal part 12 of the snail-shaped horn 1 when it passes through the snail-shaped horn 1, thereby improving the service life of the snail-shaped horn 1. The adapter 3 serves as a connector between the snail-shaped horn 1 and the cover 2, fixing the cover 2 to the outside of the snail-shaped horn 1 to form a whole. Secondly, since the snail-shaped horn 1 needs to transmit sound through its horn opening, the cover 2 is not a fully enclosed shape, but has an opening that is aligned with the horn opening, so that the snail-shaped horn 1 can be used normally.

[0047] In actual production, the installation design position of the snail horn 1 of many vehicle models has been fixed and maturely used, and the embodiment sets the fixed part 22 detachably connected with the adapter 3 on the cover body 2, realizes the individualization of the cover body 2, can produce the cover body 2 separately, and applies the cover body 2 through the fixed part 22 to the vehicle body on which the snail horn 1 has been installed, and improves the waterproof level of the horn of the existing vehicle model.

[0048] As shown in Figure 4 The cover 21 includes the side baffle 211 arranged on one side of the metal part 12 of the snail horn 1, and the protection eave 212 arranged at the end of the side baffle 211 and extending to one side of the plastic part 13 of the snail horn 1. After the horn assembly is installed on the vehicle body, the projection range of the protection eave 212 can cover the connection position of the plastic part 13 and the metal part 12 of the snail horn 1.

[0049] The advantage of the design is that, considering that the cover body 2 needs to occupy the installation space of the accessories of the snail horn 1, and since the available space of the front part of the vehicle body is limited due to the integration of a large number of structures, the cover body 2 is designed to be a half-covered shape, only the protection eave 212 shielding the top surface of the snail horn 1 and the side baffle 211 on one side of the metal part 12 are designed. Through structural design, as long as the projection range of the protection eave 212 can cover the connection position of the plastic part 13 and the metal part 12 of the snail horn 1 after the horn assembly is installed on the vehicle body, the water flow flowing into the high-position gap of the vehicle body will not enter the connection position of the plastic part 13 and the metal part 12 of the snail horn 1 when passing through the snail horn 1, and the waterproof level of the connection position of the plastic part 13 and the metal part 12 of the snail horn 1 can be improved.

[0051] The protective eave 212 is the upper top protection part of the snail-shaped horn 1, needs to bear the main water flow blocking effect, and the design of not completely covering the cover body 2 has the risk of water inlet at the opening, so the protective eave 212 not only has good water flow guiding performance, but also cannot splash to the snail-shaped horn 1 at the lower part of the protective eave 212 when the water flow passes through the end of the protective eave 212, therefore, the circular arc section 200 is designed for water flow guiding, the water flow is not easy to splash when washing to the top of the circular arc, and is quickly divided to the inclined surface section, the two outward expanding inclined surface sections can make the water flow away from the snail-shaped horn 1 after being washed out, and reduce the possibility of water inlet of the snail-shaped horn 1.

[0052] As shown in Figure 4 , the cover 21 further includes a bottom baffle 213 vertically connected with the side baffle 211 and the protective eave 212 respectively. The bottom baffle 213 can prevent the splashing water flow at the bottom of the connection part of the snail-shaped horn 1, and can also strengthen the connection strength between the side baffle 211 and the protective eave 212, improve the anti-vibration performance, and have better stability.

[0053] As shown in Figure 5 , the fixing part 22 is arranged on the outer side wall of the protective eave 212, and specifically, the fixing part 22 is fixed on the first inclined surface section 300.

[0054] Further, the reinforcing rib 23 is arranged between the fixing part 22 and the protective eave 212. Since the fixing part 22 bears the adapter fixing function with the adapter 3, it needs to bear the continuous vibration of the connection part during use, and therefore the reinforcing rib 23 is arranged to strengthen the connection strength between the fixing part 22 and the protective eave 212.
