Description

Combined double-action brushless tool switch assembly

Technical Field

The utility model belongs to the technical field of lithium electricity brushless tool technique and specifically relates to a combination formula double action brushless tool switch assembly is related to.

Background

At present, two schemes are mainly adopted for a control switch used on a lithium electric brushless tool, one scheme is that a large-current breaking function and a signal control breaking function are integrated on the same switch, the scheme is generally used for a brushless tool with working current less than 25A, if the large-current breaking and signal integration switch is designed to be applied to large-power brushless tools such as a 230 angle grinder, and the like, the size of the switch is overlarge, so that the handle holding comfort level is influenced due to overlarge size of a handle shell. Another solution is to arrange separate high current switches and separate signal switches in different areas of the handle, which results in poor production efficiency in actual production. In addition, for a lithium-ion brushless tool requiring a double action switch, the prior art solution tends to be more complex.

SUMMERY OF THE UTILITY MODEL

The not enough to prior art, the utility model provides a modular two-action brushless tool switch assembly can effectively solve the prior art problem.

The utility model provides a technical scheme that its technical problem adopted is: a modular dual action brushless tool switch assembly comprising: a housing; a base disposed within the housing; the signal switch and the high-current switch are arranged on the base; a trigger movably mounted on the base; when the trigger works, the large-current switch is triggered firstly, and then the signal switch is triggered.

In the above technical solution, further, an elastic mechanism for driving the trigger to reset is provided in the base.

In the above technical scheme, further, a limit groove is arranged on the base, and the limit groove is used for limiting the trigger to deflect relative to the base after the trigger moves transversely relative to the base for a certain distance.

In the above technical scheme, further, the limiting groove includes a first sliding groove and a second sliding groove, the second sliding groove is of an L-shaped structure, the tail of the trigger is in sliding fit with the first sliding groove, and the middle of the trigger is in sliding fit with the second sliding groove.

In the above technical solution, further, the elastic mechanism includes a first spring and a second spring, the first spring is longitudinally disposed with respect to the base, and the second spring is transversely disposed with respect to the base.

In the above technical solution, further, two ends of the first spring respectively abut against the opposite middle positions of the base and the trigger; and two ends of the second spring are respectively abutted against the middle area of the base and the tail area of the trigger.

The utility model has the advantages that: the signal switch and the large current switch are respectively arranged on a base, the opening and closing conditions of the switches at two positions are controlled by the trigger with two-section type stroke, on the basis of realizing the same function, the structure is more compact, the installation and the layout are convenient, and the production efficiency and the reliability are improved.

Detailed Description

Referring to fig. 1-4, the embodiment of the present invention is shown: a combined double-action brushless tool switch assembly comprises a shell 1, wherein a base 2 is arranged in the shell 1, a large-current switch 4 is fixedly installed at the front end of the base 2, and a signal switch 3 is fixedly installed at the middle end of the base 2; meanwhile, two sides of the rear end of the base 2 are provided with first sliding chutes 6, two sides of the middle end of the base 2 are provided with second sliding chutes 7, and the second sliding chutes 7 are in L-shaped structures; a trigger 5 is assembled on a base 2, a second convex part 11 and a first convex part 10 which are matched with a second sliding groove 7 and a first sliding groove 6 are respectively arranged at the middle end and the tail end of the trigger 5, the lower half part of the trigger 5 is exposed outside a shell 1, and the head of the trigger 5 can be longitudinally pressed after the trigger 5 transversely slides firstly due to the shapes of the first sliding groove 6 and the second sliding groove 7. Therefore, the trigger has two strokes during operation, the trigger 5 needs to be pushed forwards for a distance in a transverse mode, then the vertical section of the second sliding groove 7 can be pressed upwards, the first half section of the trigger triggers the large-current switch 4 to work firstly, and the second half section triggers the signal switch 3.

In order to realize the automatic return of the trigger 5 when the trigger is not stressed, the trigger further comprises an elastic mechanism, the elastic mechanism comprises a first spring 8 and a second spring 9, the first spring 8 is longitudinally arranged relative to the base 2, and the second spring 9 is transversely arranged relative to the base 2; two ends of the first spring 8 respectively abut against the opposite middle positions of the base 2 and the trigger 5; two ends of the second spring 9 respectively abut against the middle area of the base 2 and the tail area of the trigger 5.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and the present invention is not departed from the technical solution of the present invention, and the made simple modification, equivalent change or modification all fall into the protection scope of the present invention.
