Abstract

The utility model provides a waterproof shell of a motorcycle instrument, relates to the technical field of vehicle instruments, and solves the problems of poor tightness, complex assembly and inconvenient maintenance of the existing shell. The shell comprises a panel, a panel support and a rear shell, wherein liquid silica gel is integrally formed on the rear shell, interference fit is formed between the liquid silica gel and the panel support, and the panel is connected with the rear shell through a fixing screw and is sealed through compressing the liquid silica gel. The full-lamination screen assembly is mounted on the back of the panel and electrically connected with the PCBA circuit board, and the PCBA circuit board is arranged inside the rear shell. The structure omits the traditional waterproof rubber ring or ultrasonic welding process, improves the assembly efficiency, enhances the waterproof reliability and is convenient to detach and maintain. The utility model has the advantages of simple structure, good sealing performance, low cost and strong applicability, and is suitable for motorcycle instrument products with higher requirements on waterproof level.

Description

Waterproof shell of motorcycle instrument Technical Field The utility model relates to the technical field of vehicle instruments, in particular to a waterproof shell of a motorcycle instrument. Background Motorcycle instruments are important devices for displaying motorcycle mileage, gear, speed and indicating the running state of a motorcycle, and are generally equipped with a housing to protect the internal components thereof. In view of the use characteristics of motorcycles, the casing needs to have a good waterproof function, and a common casing consists of an upper cover and a lower cover. However, the prior art has a number of drawbacks: The existing waterproof structure is generally provided with waterproof rubber between the upper cover and the lower cover, and the waterproof rubber and the upper cover are pressed by plane contact. However, the plastic piece may deform or have uneven surface, so that the upper and lower covers are not tightly pressed with the rubber, and the sealing is incomplete, thereby causing the water inflow of the instrument. The ageing of the sealing ring affects the sealing effect, and the joint of the bottom shell and the upper shell of part of motorcycle instruments adopts the sealing ring to carry out waterproof sealing. However, after long-time use, the sealing ring is easy to age and deform, so that the sealing effect is poor, and the sealing ring is inconvenient to replace in the conventional equipment. The waterproof performance detection effect is poor, and when the motorcycle instrument shield with a certain radian is used for waterproof performance test, two modes are generally adopted at the present stage. One is to build a closed environment and then soak and inflate, and the tightness detection is carried out by detecting the density of bubbles in water, the detection effect of the mode is general, the preparation work is more, and the mode is generally only suitable for detecting a small number of samples, and the other is to build a closed environment and then inflate, and then the tightness of the motorcycle instrument shield is detected by using the subsequent pressure release condition analysis, so that the waterproofness of the motorcycle instrument shield is analyzed. However, the detection device of the motorcycle instrument shield with the arc-shaped structure at present has poor effect on the formed closed environment, when raining, rainwater is often directly hit on the outer glass of the motorcycle instrument, and a certain connecting seam exists between the outer glass of the instrument and the shell of the electric motorcycle, so that when the rainfall reaches a certain degree, the water seepage phenomenon is easy to occur. Therefore, we make improvements to this and propose a waterproof housing for a motorcycle instrument. Disclosure of utility model The utility model aims to solve the problems of the prior art. In order to achieve the aim of the utility model, the waterproof shell of the motorcycle instrument comprises a panel, a panel support, a rear shell, liquid silica gel, fixing screws, a PCBA circuit board and a full-lamination screen assembly, wherein the panel support is arranged between the panel and the rear shell, the liquid silica gel and the rear shell are arranged on the rear shell in an integrated forming mode, the panel and the panel support are in interference pre-pressing connection through the liquid silica gel on the rear shell, and the panel, the panel support and the rear shell are fixed through the fixing screws. As a preferable technical scheme of the utility model, the left side and the right side of the liquid silica gel on the rear shell are in interference fit with the panel bracket. As a preferable technical scheme of the utility model, the panel is positioned on one side of the panel bracket far away from the rear shell and is tightly attached to the panel bracket. As the preferable technical scheme of the utility model, the fixing screw sequentially passes through the panel and the panel bracket and then is in threaded connection with the rear shell. As a preferred technical solution of the present utility model, the liquid silica gel completely covers the contact area between the rear shell and the panel bracket. As a preferable technical scheme of the utility model, the full-fitting screen component is arranged on one side surface of the panel, which is close to the rear shell. As the preferable technical scheme of the utility model, the PCBA circuit board is arranged in the rear shell and is fixedly connected with the inner wall of the rear shell. As a preferable technical scheme of the utility model, the fixing screws are uniformly distributed along the edges of the panel and the rear shell. As the preferable technical scheme of the utility model, the full-lamination screen assembly is in circuit connection with the PCBA circuit board. Compared with the prior art, the utility model has the beneficial effects t
