Description

Instrument end cover waterproof construction

Technical Field

The utility model relates to an electric motor car instrument seals technical field, especially relates to an instrument end cover waterproof construction.

Background

The non-motor vehicle or the electric bicycle is provided with an instrument, and the instrument has the main function of displaying user required information such as the current electric quantity, gear, running speed, accumulated running kilometers and the like of the battery of the electric bicycle. However, the meter often works in an open air environment, and electronic components such as a PCB board are arranged inside the meter shell, so that when liquid invades into the meter from a gap between the meter end cover and the shell, the electronic components such as the PCB board are affected with damp and fail, and the service life of the meter is shortened.

Adopt the glued membrane structure between end cover and the casing under the prior art, the assembly work is long, and the cost is higher, and water-proof effects is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an instrument end cover waterproof construction has solved the gap between prior art lower extreme cover and the casing and has invaded moisture after, reduces instrument life's problem.

To achieve the purpose, the utility model adopts the following technical proposal: the utility model provides an instrument end cover waterproof construction, including casing and apron, casing circumference encloses and establishes into the lateral wall, the lateral wall up end is provided with the recess, the recess intussuseption is filled with soft silica gel, be formed with first buckling part on the lateral wall, be formed with second buckling part on the apron, first buckling part with the mutual joint of second buckling part, be formed with the floor on the apron, the floor is pegged graft in the recess.

Preferably, the groove is circumferentially arranged on the upper end face of the side wall, and the rib plate is circumferentially arranged on the inner wall of the cover plate.

Preferably, the waterproof meter structure further comprises a display panel, the display panel is inserted into the housing, and the display panel is connected with the inner side of the side wall.

Has the advantages that: install soft silica gel additional through the recess on the casing lateral wall, make the floor on the apron peg graft in above-mentioned recess, fill the gap through soft silica gel between floor and the recess, prevent that external steam or liquid from invading to display panel, avoid the PCB board to wet failure, promote the life of instrument.

Drawings

FIG. 1 is a sectional view of the instrument structure of the present invention;

fig. 2 is a partial enlarged view of the sealing structure of the present invention.

In the figure: 1-cover plate; 11-a rib plate; 2-a display panel; 3-a shell; 31-groove.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures associated with the present invention are shown in the drawings, not all of them.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integral to one another; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or may be connected through the use of two elements or the interaction of two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present application, unless expressly stated or limited otherwise, the recitation of a first feature "on" or "under" a second feature may include the recitation of the first and second features being in direct contact, and may also include the recitation of the first and second features not being in direct contact, but being in contact with another feature between them. Also, the first feature "on," "above" and "over" the second feature may include the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "right", and the like are used based on the orientations and positional relationships shown in the drawings, and are only for convenience of description and simplification of operation, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

Generally, waterproof is carried out between casing and the apron under the prior art through installing the glued membrane structure additional, but the process of filling the glued membrane structure is comparatively complicated, need set up the process of one step of filling the glued membrane structure alone, and it is long when increasing the assembly, reduces production efficiency, and ageing phenomenon can appear in the long-time use of glued membrane structure simultaneously, can't reach waterproof requirement after ageing, still can intake water and reduce instrument structure's life.

In order to solve the problem, as shown in fig. 1 to 2, the utility model provides an instrument end cover waterproof construction includes casing 3 and

apron

1, 3 circumference of casing enclose and establish into the lateral wall, the lateral wall up end is provided with recess 31, the intussuseption of recess 31 is filled with soft silica gel, be formed with first buckling parts on the lateral wall, be formed with second buckling parts on the apron 1, first buckling parts and the mutual joint of second buckling parts, be formed with floor 11 on the apron 1, floor 11 pegs graft in recess 31.

Through 11 soft silica gel mutual butt that pegs graft in recess 31 can be filled with recess 31 inside of floor, realize the sealed in clearance between recess 31 and the floor 11, prevent external liquid invasion, promote the waterproof grade of instrument panel position, can prevent like this that the PCB board from weing inefficacy, the life of extension instrument, simultaneously in the equipment directly fill soft silica gel in above-mentioned recess 31, because the existence of recess 31, make the workman glue the process more accurate when processing, make the packaging efficiency of instrument higher.

The utility model discloses a recess 31 is circumference setting on the lateral wall up end, and floor 11 is circumference setting at apron 1 inner wall, and the same floor 11 of shape and recess 31 can seal whole apron 1 and casing 3 along circumference and prevent that external steam from getting into, promote the waterproof grade of instrument structure, prolong instrument structure's life.

The instrument waterproof construction still includes display panel 2, and display panel 2 pegs graft on casing 3, and display panel 2 meets with the lateral wall inboard, because the sealed of above-mentioned soft silica gel, can prevent that external steam from getting into, prevents that display panel 2 from appearing atomizing phenomenon, makes display panel 2's display effect more clear.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention.
