Description

A kind of assembling structure, backlight module and display module

Technical field

This utility model relate to a kind of backlight module and display module assembling structure and using this assembling structure.

Background technology

In structure design, a lot of schemes there will be the scheme that two structural members are assembled together, existing design, as Shown in Fig. 1, assembly parts are assembled together by certain fixed form with bearing part, this scheme, when needs management and control fitted position, Dimensional tolerance need to be accomplished bigger, the salient position of such as bearing part to the size of assembly parts end face, and the tolerance of this size need to be examined Consider the dimensional tolerance of assembly parts itself；Meanwhile, between bearing part and assembly parts, reality can not be equally complete with Design Theory Flat contact, has gap between both contacts, so the tolerance of this size also needs to consider this gap value.Then practical set size Tolerance value become big so that fitting tight is strong, and precision is the highest.But, more and more diversified at current product, product is tied The requirement of structure is increasingly tightr, and precision is more and more higher, and reliability requirement is more and more higher.Management and control to product size tolerance, more Come the most important, particularly the tolerance of fitted position, therefore, need research badly and can reduce the tolerance value of fitted position so that assembling is more The most reliable, precision higher assembling structure.

Utility model content

In order to solve above-mentioned the deficiencies in the prior art, this utility model provides a kind of assembling structure, its at assembly parts and The contact surface of bearing part devises contact site, then both can fit together closely, and defines localized contact or point cantact, no The problem that there is gap so that fitted position tolerance is less, and precision is higher.

This utility model additionally provides a kind of backlight module and display module.

Technical problem to be solved in the utility model is achieved by the following technical programs:

A kind of assembling structure, including bearing part and the assembly parts being assemblied in described bearing part；Described bearing part and/or dress Accessory is provided with at least one contact site in the side that described bearing part and assembly parts contact with each other.

Further, described contact site is salient point or boss.

Further, described contact site top is arc.

Further, described contact site cross section is rule or irregular figure.

Further, described regular figure is circular, square, oval or triangle.

Further, the contact site of described bearing part and assembly parts mutually staggers setting.

Further, described bearing part and assembly parts are one-body molded with respective contact site.

A kind of backlight module, including above-mentioned assembling structure.Wherein, described bearing part is framework, and described assembly parts are glue Frame；Or, described bearing part is glue frame, and described assembly parts are light guide plate；Or, described bearing part is framework, and described assembly parts are for leading Tabula rasa.

A kind of display module, including above-mentioned backlight module.

This utility model has the advantages that this assembling architecture is simple, designs ingenious, in assembly parts and carrying The contact surface of part devises contact site, then can fit together closely both during assembling, define localized contact or point cantact, The problem that there is not gap so that fitted position tolerance is less, and precision is higher；Solve both existence assembling public affairs in prior art Difference causes greatly the problem that assembling is not tight and precision is the highest.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of prior art assembling structure；

Fig. 2 is the schematic diagram of this utility model one embodiment assembling structure；

Fig. 3 is the schematic diagram of another embodiment of this utility model assembling structure.

Detailed description of the invention

With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.

As in figure 2 it is shown, which show a kind of assembling structure.Described assembling structure is held described in including bearing part 1 and being assemblied in Assembly parts 2 in holder 1；Described bearing part 1 or assembly parts 2 are arranged in the side that described bearing part 1 and assembly parts 2 contact with each other There is at least one contact site 3 so that face contact originally becomes point cantact or localized contact, described bearing part 1 and dress after assembling Accessory 2 can fit together closely, the problem that there is not gap so that fitted position tolerance is less, and precision is higher.

Making further improvements, described contact site 3 top is cambered design, but is not limited to this.Described contact site 3 cross section For rule or irregular figure, regular figure is the most circular, square, oval or triangle etc..

Making further improvements, described contact site 3 preferably but is not limited to salient point or boss.This salient point or the shape of boss, Position, big I are according to the shape size of specific product, the designed, designed such as stressing conditions.

Make further improvements, as it is shown on figure 3, described bearing part 1 and assembly parts 2 are mutual at described bearing part 1 and assembly parts 2 The side of contact is provided with at least one contact site 3, and the contact site 3 of described bearing part 1 and assembly parts 2 mutually staggers and sets；Make Obtaining face contact originally and become point cantact, after assembling, described bearing part 1 and assembly parts 2 can fit together closely, and do not exist The problem in gap so that fitted position tolerance is less, and precision is higher.

Making further improvements, described bearing part 1 and assembly parts 2 are one-body molded with respective contact site 3.

It should be noted that described bearing part can be plastic parts or metalwork, assembly parts can be metalwork or plastic cement Part.

This utility model additionally provides a kind of backlight module, it uses above-mentioned assembling structure.When implementing, described Bearing part can be framework, then assembly parts are glue frame；Or, described bearing part can be glue frame, then assembly parts are light guide plate；Or, Described bearing part can also is that framework, then assembly parts are light guide plate, but are not limited to this.It should be noted that described bearing part Can be plastic parts or metalwork, assembly parts can be metalwork or plastic parts.

A kind of display module, it has above-mentioned backlight module.

Embodiment described above only have expressed embodiment of the present utility model, and it describes more concrete and detailed, but also Therefore the restriction to this utility model the scope of the claims can not be interpreted as, as long as using equivalent or the form institute of equivalent transformation The technical scheme obtained, all should fall within protection domain of the present utility model.
