Description

Key-type selector with drainage structures

Technical Field

The utility model relates to an automatically controlled technical field of automotive electronics especially relates to a button selector with drainage structures.

Background

Most of gear shifters in the original automobile technology are mechanical rod-shaped, so that the requirements on the driving skill of a driver during gear shifting operation are high, the occupied space of a cab is large, and in the design of a gear shifting mechanical structure, the work is complex and the difficulty is high.

In contrast, with the rapid development of automotive electronics, modern automobiles increasingly use electronic gear shifters to communicate with transmission controllers to meet gear changes in everyday driving; meanwhile, the key is used for shifting gears, so that the driving and gear shifting modes are enriched, the space in the vehicle is liberated, the technological sense is increased, and the driving experience is obviously improved.

However, most of the existing market is knob type or gear type gear shifters, few key types are small, gear shifting is difficult, and corresponding protective equipment is not arranged around the keys, so that water is easy to enter, and the service life of the keys is further shortened.

SUMMERY OF THE UTILITY MODEL

To the not enough among the prior art, the utility model provides a can make the moisture discharge selector that gets into in the selector outer button shifter that has drainage structures.

In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides a button selector with drainage structures, is including having the shell that holds the chamber, the button subassembly install in the appearance intracavity of shell, the button subassembly with the shell assembly back between the two reserve have with the drainage channel of the drainage structures intercommunication that sets up on the shell, drainage structures is including the annular chamber and the outlet of walking water of intercommunication each other, the annular chamber of walking water is located the shell holds the intracavity, the outlet is seted up in on the lateral wall of shell.

In the technical scheme, the shell comprises an upper shell and a lower shell which are integrally arranged and are mutually communicated, and the water outlet is formed in the side wall of the joint of the upper shell and the lower shell.

In the technical scheme, the annular water running cavity is communicated with the water outlet through the flow passage.

In the above technical solution, a height difference is provided between the inlet of the flow channel and the outlet of the flow channel.

In the above technical solution, the key assembly includes a key, a key inner shell, and a light guide ring.

Compared with the prior art, the utility model discloses following beneficial effect has: the annular chamber of walking water sets up in the cavity, forms bilayer structure, and outside drainage, each functional unit of inlayer assembly realizes protective structure through cooperation annular inner chamber wall structure between each subassembly, and the annular chamber of walking water of infiltration track accessible flows through runner to outlet, the outlet set up in on the lateral wall of shell, indent formula outlet design has stopped debris such as dust and has directly got into the inside approach of body by the outlet, and provides bigger space for the drainage, effectively prolongs selector life.

Drawings

Fig. 1 is a schematic view of the explosion structure of the present invention.

Fig. 2 is a schematic sectional view of one of the gears of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 2, a key shifter with a drainage structure includes a housing 1 having a cavity, a key assembly is installed in the cavity of the housing 1, and a drainage channel communicated with the drainage structure arranged on the housing 1 is reserved between the key assembly and the housing 1 after the key assembly and the housing 1 are assembled.

The shell 1 comprises an upper shell 10 and a lower shell 11 which are integrally arranged and are mutually communicated, and the drainage structure is arranged at the joint of the upper shell 10 and the lower shell 11. The drainage structure comprises an annular water-running cavity 12 and a water outlet 13 which are communicated with each other, the annular water-running cavity 12 is positioned in the containing cavity of the shell 1, and the water outlet 13 is arranged on the outer side wall of the shell 1.

The annular water-running cavity 12 is communicated with the water outlet 13 through a flow passage 14, and a height difference is arranged between the inlet of the flow passage 14 and the outlet of the flow passage 14.

Outer and inlayer are cut apart into with 1 cavity of shell to the annular chamber of running water, outer drainage and waterproof construction of forming, the inlayer is functional unit installation cavity, the opening part interference fit of light guide ring 23 and

last casing

10, 21 circumference an organic whole of button are provided with the buckle, it is fixed as an organic whole with button inner shell 22 joint, button 21 card is in the opening part of light guide ring 23, button inner shell 22 extends to 1 cavity below of shell, in 11's of casing under promptly the cavity, through pressing button 21 surface, it is downward along vertical direction to make button 21 drive button inner shell 22, hold the button interact on the conductive component of intracavity with the same casing 11 that lies in down, realize the resilience of power and push down.

When water marks exist on the gear shifter, water can permeate downwards along a drainage channel formed by assembling the key and the light guide ring, water permeating from any side of the light guide ring can enter the annular water passing cavity, after the water is collected in the annular water passing cavity, a height difference is arranged between an inlet of the flow channel 14 and an outlet of the flow channel 14, namely one end of the flow channel 14 communicated with the annular water passing cavity is higher than one end of the flow channel communicated with the water outlet 13, and finally the collected water can be discharged out of the shell along the water outlet 13, so that the service life of the gear shifter is effectively prolonged.

The above is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, and it should be appreciated by those skilled in the art that various equivalent substitutions and obvious changes made in the specification and drawings should be included within the scope of the present invention.
