Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, a housing assembly of the present invention includes

[0037] The housing 1 is formed with a through hole;

[0038] The top bar 2 is axially slidably arranged in the through hole, and one end of the top bar 2 on the outside of the housing 1 is equipped with a keycap 3, and one end on the inside of the housing 1 , for controlling the key switch 10 arranged in the housing 1;

[0039] a biasing member, the biasing force of which acts on the keycap 3 to reset the keycap 3 after being pressed by an external force;

[0040] A sealing element is arranged between the top bar 2 and the through hole.

[0041] Since the shell assembly cancels the setting of the stainless steel collar on the shell 1, the plastic shell 1 is no longer subject to the extrusion force of the collar, therefore, it is possible to avoid the generation of microcracks at the position where the button is installed on the shell 1, As a result, the yield rate of the...

Abstract

The invention discloses a shell assembly and a watch. The shell assembly comprises a shell on which a through hole is formed; a prop which is arranged in the through hole and can axially slide, one end of the prop, which is located at an outer side of the shell, being equipped with a key cap, and one end located at an inner side of the shell being used for controlling a key switch arranged in theshell; a biasing member of which biasing force acts on the key cap so as to enable the key cap to be reset after external force pressing; and a sealing member arranged between the prop and the throughhole. The shell assembly provided by the invention is low in manufacturing cost, the generation of microcracks at the shell is completely eradicated, the assembly efficiency and yield are relativelyhigh, and hand feeling of pressing is relatively good.

Description

technical field [0001] The invention relates to the field of watches, in particular to a casing assembly and a watch. Background technique [0002] A watch is a precision instrument for timing / displaying time. If water accidentally enters the watch during use, it will affect the accuracy of the watch’s timing, and may even cause the watch to not work properly. Therefore, the waterproof of the watch is very important. The part of the watch that is most likely to enter water is the key, so the waterproof of the key is very important. [0003] The existing shell assembly is to press the stainless steel collar to the front shell through the interference fit of the jig to ensure that the front shell and the collar are sealed and waterproof, then assemble the sealing ring and the gasket on the ejector rod, and pass one end of the ejector rod through the A snap ring is buckled on the back of the stainless steel collar and installed on the front shell, a keycap is installed on the ...
