Problems solved by technology

[0007] However, because the internal space of the mobile phone is very limited, the gear assembly that can be used is also very small (for example, the diameter of the second gear part 222X is only about 2mm), which makes the manual assembly of the gear assembly very difficult. It is easy to reassemble because the gears do not mesh well with each other, and the assembly efficiency is significantly restricted

Embodiment approach 1

[0058] figure 1 is a perspective view schematically showing a jig according to Embodiment 1 of the present invention, figure 2 It is a side cross-sectional view schematically showing the jig according to Embodiment 1 of the present invention, and shows a state cut by a plane passing through the diameter of the knob.

[0059] The clamp 100 includes: a base 110; a knob 120, which is rotatably arranged on the base 110; and a transmission part 130, which is connected to the knob 120 and can be connected to the Figure 4 , Figure 5 Rotating member 220X of gear assembly 200X is shown coupled to transmit rotation of knob 120 to rotating member 220X of gear assembly 200X.

[0060] Here, the base 110 is substantially in the shape of a plate whose dimension in the Z direction is much smaller than the dimensions in the X and Y directions. Further, a bearing hole 111 extending in the Z direction is formed at the center of the base 110 , and the bearing hole 111 is recessed from the s...

Embodiment approach 2

[0073] image 3 It is a side cross-sectional view schematically showing the jig according to Embodiment 2 of the present invention, and shows a state obtained by cutting a plane passing through the diameter of the knob.

[0074] The structure of the jig 100A of this embodiment differs from the structure of the jig 100 of the above-mentioned first embodiment only in that it further includes a bracket 140. Therefore, the same components as those of the jig 100 of the above-mentioned first embodiment are given the same reference numerals and omitted. It repeats the description.

[0075] The bracket 140 is disposed on the base 110 and supports the gear assembly 200X.

[0076] Here, in the gear assembly 200X, one end ( Figure 4 The lower end of the center) is provided with an opening, and the bracket 140 supports the gear assembly 200X so that at least a part of the opening is exposed. Specifically, the bracket 140 has a housing recess 141 that houses and supports at least a par...

Abstract

A jig that helps improve assembly efficiency of tiny gear assemblies included in small electronic products. The jig of the present invention is used for the assembly of a gear assembly. The gear assembly includes a barrel and a rotating part arranged in the barrel. The rotating part includes a plurality of gears. The jig includes: a base; a knob, the knob can and a transmission part, which is connected with the knob and can be connected with the rotation part of the gear assembly, so as to transmit the rotation of the knob to the gear assembly the rotating parts.

Description

technical field [0001] The invention relates to a jig used for the assembly of a gear assembly. Background technique [0002] With the improvement of living standards, people have more and more requirements for the products they use every day. [0003] For example, in the field of small electronic products, on the one hand, people hope that the product can be small enough to be portable, and on the other hand, they hope that the product has multiple functions to meet the needs of different occasions. [0004] In the case of a mobile phone, which is a representative example of the field of small electronic products, it is generally desired to enhance the camera function while maintaining the miniaturization. [0005] In response to the above demands, manufacturers have developed a structure that integrates a gear assembly in a mobile phone to drive the camera to achieve zoom shooting. [0006] As an example of the above-mentioned gear assembly, there is Figure 4 and Figu...
