Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric horn, concretely is a kind of electric horn plastic shell with waterproof grille. BACKGROUND

[0002] At present, electric horn is often affected by assembly position when being installed on the car body. In order to ensure the requirement of product sound level, the horn sound outlet is directed to the front direction of the car. In this case, rainwater often enters electric horn when it rains or when the car is washed, causing the product to lose function. In order to solve this problem, a waterproof cover is added at the horn outlet position to solve the water entry problem. The waterproof cover is separate from the plastic shell and is connected to the plastic shell by buckling or bonding, etc. to play a waterproof role. However, this method increases a part, and also increases the installation, gluing and other processes, increasing the cost of the product. At the same time, the two parts connected by buckling or bonding also have the risk of falling off. SUMMARY

[0003] In view of the above problems of avoiding water entering electric horn by bonding waterproof cover on plastic shell, the purpose of the utility model is to provide a kind of electric horn plastic shell with waterproof grille.

[0004] The utility model discloses a kind of electric horn plastic shells with waterproof grille, which is characterized by the following technical solutions:

[0005] The utility model discloses a plastic shell with integrated injection molding sound outlet, waterproof grille is provided in the sound outlet, waterproof grille is set from outside to inside along the arc surface of plastic shell.

[0006] Among them: the cross section of waterproof grille in height direction is "V" type, cylinder, half cylinder or half arc.

[0007] The waterproof grille is integrally injection molded with the plastic shell and the sound outlet.

[0008] The plastic shell is fixedly connected with the electric horn by vertical installation.

[0009] The utility model discloses an electric horn plastic shell with waterproof grille, which has the advantages and positive effects of:

[0010] The utility model discloses a waterproof grille in the sound outlet of plastic shell, which can block rainwater from entering the electric horn when the electric horn is installed on the car body, reducing the risk of product failure. Since the plastic shell and the waterproof grille are integrated, the basic sound performance of the product is not affected, and the waterproof cover does not need to be installed and connected, thereby reducing the number of parts and installation processes, and further reducing the cost and the risk of two parts falling off in the traditional split waterproof method, improving the stability of the product. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 is a structure schematic view of the utility model;

[0012] Figure 2 is a structure schematic view of the utility model;

[0013] Figure 3 is a structure schematic view of the utility model applied to an electric loudspeaker;

[0014] Among them: 1 is plastic shell, 2 is sound emitting port, 3 is waterproof grille. Specific implementation mode

[0015] The utility model will be further described in detail in combination with the drawings.

[0016] As Figure 1 , Figure 2 shown, the utility model discloses plastic shell 1 has the sound emitting port 2 of integrative injection molding, is equipped with waterproof grille 3 in sound emitting port 2, and waterproof grille 3 sets up along the circular surface of plastic shell 1 from outside to inside.

[0017] The section of waterproof grille 3 in height direction is " V " type, cylinder, half cylinder or half arc, and the section of waterproof grille 3 in height direction of this embodiment is " V " type.

[0018] This embodiment sets up a waterproof grille 3 on the circular surface of plastic shell 1 in sound emitting port 2.

[0019] The waterproof grille 3 of this embodiment is integrative injection molding with plastic shell 1 and sound emitting port 2.

[0020] As Figures 1 to 3 shown, the utility model adopts the mode of injection molding and processes into the plastic shell 1 of sound emitting port 2 with waterproof grille 3, coats sealing glue on plastic shell 1, and is bonded and fixed with electric loudspeaker semi-finished product through vertical installation mode.
