Abstract

The utility model provides an operating handle, is including dialling twist switch, button module, panel and shell, dials twist switch and button module and assembles in the panel in parallel, and operating handle is constituteed with the shell assembly to the panel. The assembly part of the key module consists of a hard colloid and a soft colloid, and the hard colloid and the soft colloid are formed into a whole through secondary injection molding. The panel comprises a poking and twisting hole and a key part, the poking and twisting hole corresponds to the poking and twisting switch, the key part corresponds to the key module, the key part is made of soft rubber, and the key part and the panel are integrated through secondary injection molding. The button module assembly portion of this scheme adopts two-layer structure of hard soft an organic whole, through secondary injection moulding, can guarantee that the circuit of button module lower part is waterproof. In addition, the key part and the face shell adopt the same design concept, and further waterproof design is carried out from the outside.

Description

Waterproof operating handle

Technical Field

The invention relates to the technical field of handles, in particular to a waterproof operating handle.

Background

The use environment of non-road vehicles such as agricultural tractors and construction machines is different from that of road vehicles. The non-road vehicle is mainly used for farmland operation or construction of construction sites, and the using environment of the non-road vehicle is very complicated and severe. For example: the operating handle is one of the important accessories of the vehicle, and its main function is to provide a signal to the vehicle controller. The operating handle is provided with electronic elements or electronic components, and the handle is required to be designed to be waterproof according to the requirement of the operating environment, so that the phenomenon that the operating handle fails due to the fact that moisture enters a circuit is avoided.

Disclosure of Invention

In order to achieve the purpose, the waterproof operating handle comprises a toggle switch, a key module, a panel and a shell, wherein the toggle switch and the key module are assembled in the panel in parallel, and the panel and the shell are assembled to form the operating handle. The assembly part of the key module consists of a hard colloid and a soft colloid, and the hard colloid and the soft colloid are molded into a whole through secondary injection molding. The panel comprises a poking and twisting hole and a key part, the poking and twisting hole corresponds to the poking and twisting switch, the key part corresponds to the key module, the key part is made of soft rubber, and the key part and the panel are integrated through secondary injection molding.

Detailed Description

A waterproof operating handle comprises a toggle switch 10, a key module 20, a panel 30 and a shell 40.

The toggle switch 10 and the key module 20 are assembled in parallel in the panel 30, and the panel 30 and the housing 40 are assembled to form an operating handle.

The assembly part 21 of the key module 20 is composed of a hard colloid 211 and a soft colloid 212, and the hard colloid 211 and the soft colloid 212 are formed into a whole through secondary injection molding. The circuit part of the key module is positioned in the circuit accommodating cavity below the soft colloid 211.

The panel 30 includes a hole 31 and a key portion 32, the hole 31 corresponds to the toggle switch 10, the key portion 32 corresponds to the key module 20, wherein the key portion 32 is made of soft plastic, and the key portion 32 is integrated with the panel 30 through secondary injection molding.

The existing operating handle and the key module are not generally designed to be waterproof, and even if the existing operating handle and the key module are designed to be waterproof, the mode of using the sealing ring is usually selected, and the sealing ring is added to an assembly part and a circuit part of the key module. And this scheme selection is direct to be designed into the two-layer structure of hard soft an organic whole with the assembly portion of button module, through secondary injection moulding, can guarantee the uniformity of two-layer structure, can simplify the device process of button module again, and the circuit that button module lower part can be guaranteed again to the flexible glue part is waterproof.

In addition, the conventional operating handle is generally provided with a hole on the panel, and the key and the circuit part of the key are separately assembled at the hole, wherein the key penetrates out of the hole, and the circuit part is positioned below the hole. The existing panel is provided with holes, gaps exist all the time, and moisture is difficult to avoid entering a circuit part below from the gaps. This scheme button portion adopts the flexible glue material, sets up in the outside of panel, and the button is also integrative through secondary injection moulding with the panel, has guaranteed the requirement of feeling of button operation promptly, can prevent again from the panel outside that moisture from getting into the circuit of button module, further reaches waterproof requirement.

Further, the panel 30 is a square structure, and the hole of the housing 40 for assembling the panel is correspondingly square. The panel and the shell adopt corresponding square designs, can freely change 4 directions to install, are fit for the multipurpose demand.

Claims
