Lock-stopping hinge assembly and sound apparatus using same to realize lower-flicking mode

Abstract

The locking hinge subassembly includes following parts: base; lever fixture with a hook clip in front end capable of being rotated along direction of a revolving part hung by the hook clip under elastic force of base elasticity part; push rod for pushing rotation from back part of guide plate along direction of guide plate under elastic force of base elasticity part; the push rod and the base are integrated. There are hinge axis of rotation center of guide plate formed on front end, and the push rod, and rotatable hinge bracket in the base. The push rod can be separated from the hinge bracket. Advantages are: reducing number of component parts, and smooth flip down operation.

Description

technical field [0001] The invention relates to a locking hinge assembly and an audio device using the device to realize the downward spring-opening mode, in particular to the sound device which adopts the locking device to make the front part of the sound body operate in the downward spring-opening mode. Background technique [0002] figure 1 shows a car audio unit in which the front part flips down and opens and closes. As shown in the figure, the front end of the main chassis (main chassis) 11 is an interior trim panel 13; both sides of the front end of the main chassis 11 are hinge brackets 12 with hinge shafts 12'; The hinge shaft of the above-mentioned guide plate 15 can be rotated around the center, and the two ends of the above-mentioned guide plate 15 are hung on the hinge shaft of the above-mentioned hinge bracket 12, so that the above-mentioned guide plate 15 is organically combined with the above-mentioned hinge bracket; the above-mentioned guide plate 15 is pro...

AI Technical Summary

Problems solved by technology

[0008] First, in the structure of the prior art, the structure of connecting the guide plate 15 on the above-mentioned audio front-end part 18 to the above-mentioned switch plate 13 and the structure of making it bounce down are realized separately, that is, the structure including the lever fixing member 16 is realized separately. The composition is separated from the composition including the hinge bracket 12, which brings inconveniences such as an increase in parts and cumbersome assembly

[0009] Furthermore, in the structure of the prior art, the action of rotating the guide plate 15 fixing the above-mentioned acoustic front-end front member 18 around the hinge shaft cannot be performed smoothly.

That is, when the lever fixing member 16 in the combined state is separated, the above-mentioned guide plate 15 cannot automatically rotate around the hinge axis, but needs to be manually rotated by the user, which also brings some inconvenience
