Problems solved by technology

However, during the loading and unloading operation, the brackets on both sides of the plastic case are squeezed towards the notch, and excessive force will cause deformation, change the size of the bracket, and even have a safety hazard of bracket breakage

Embodiment 1

[0025] Such as figure 1 As shown, an improved embedded vehicle buzzer plastic case includes a housing 1 and a bracket, the brackets are fixedly installed on both sides of the housing 1, and the brackets include a first bracket 2 and a second bracket 3 and a third bracket 4, the first bracket 2 is fixedly connected to the housing 1, the first bracket 2 is fixedly connected to the second bracket 3, the second bracket 3 is fixedly connected to the third bracket 4, and the first bracket 2 is fixedly connected to the second bracket 3. The inner side of the second bracket 2 is provided with a buffer layer 6, and the buffer layer 6 is provided with a limit jacking column 5. Column 5, in the process of loading and unloading, effectively limits the excessive deformation of the bracket, which can not only safely and conveniently disassemble the buzzer, but also effectively protect the bracket; the angle between the first bracket 2 and the shell 1 is between 70° and 100° Between, the an...

Embodiment 2

[0027] On the basis of the previous embodiment, in order to strengthen the connection between the space-limiting top column 5 and the second bracket 3, a pull wire 7 is fixedly connected to the second bracket 3 on both sides of the top of the space-limiting top column 5. The stay wires 7 on both sides of the top post 5 enable the space-limiting top post 5 to evenly disperse the received force after the bracket is deformed, thereby increasing the service life of the space-limiting top post 5 .

Embodiment 3

[0029] On the basis of Embodiment 1, in order to strengthen the connection between the space-limiting top column 5 and the second bracket 3, a fixed plate 8 is provided on both sides of the bottom of the space-limiting top column 5 to be threadedly connected with the second bracket 3, and the fixed plate 8 is threaded through the buffer layer 6 and connected to the second bracket 3, so that the combination between the space-limiting top column 5 and the second bracket 3 is stable, and the service life of the space-limiting top column 5 is improved.

Abstract

The invention relates to an improved embedded vehicle-mounted buzzer plastic case comprising a housing and brackets. The brackets are fixedly installed at the two sides of the housing. The brackets include first brackets, second brackets and third brackets; the first brackets are fixedly connected with the housing and are fixedly connected with the second brackets; and the second brackets are fixedly connected to the third brackets. Buffer layers are arranged at the inner sides of the second brackets; and limiting top columns are arranged on the buffer layers and are fixedly connected with thebuffer layers. Because of the limiting top columns arranged at the inner sides of the brackets, the breaking risk of the brackets due to the force-caused deformation can be prevented and controlled effectively; the damages on the brackets during the mounting or dismounting process of the buzzer can be reduced substantially and thus the brackets are protected effectively; and the service life of the buzzer is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle buzzers, in particular to an improved molded case of embedded vehicle buzzers. Background technique [0002] The buzzer is an electronic sounder with an integrated structure, which is widely used as a sounding device in alarms, automotive electronics, telephones, voice prompt alarms and other products; especially in automotive electronics, the buzzer is very useful as a sounding device. frequently. [0003] The existing embedded vehicle buzzer is to fix the plastic case of the buzzer on the panel, and through the cooperation of the connector terminal, the current passes through the electromagnetic coil, so that the electromagnetic coil generates a magnetic field to drive the diaphragm to sound, but the buzzer When the buzzer needs to be disassembled due to a malfunction of the buzzer or other reasons, the fixed panel must be removed first, and then the buzzer should be reversely withdrawn from th...
