According in hermetically-sealed construction of the present utility model favourable execution mode, alternatively, described at least one, in space, be filled with lubricator.
According in another favourable execution mode of hermetically-sealed construction of the present utility model, alternatively, described at least one, space is constructed grooving shape.
According in another favourable execution mode of hermetically-sealed construction of the present utility model, alternatively, described Part III is configured to the size that its size is less than described Part I and/or described Part II.
According in another favourable execution mode of hermetically-sealed construction of the present utility model, alternatively, described Part I, Part II and Part III are all configured to lip shape.
According in the favourable execution mode of the another one of hermetically-sealed construction of the present utility model, alternatively, described framework is made up of metal material.
According in another favourable execution mode of hermetically-sealed construction of the present utility model, alternatively, described body is made up of elastomeric material, and described elastomeric material comprises rubber.
In addition, according to second aspect of the present utility model, it also provides a kind of device, is provided with at least one hermetically-sealed construction as described in above any one on this device, and described device comprises motor.
That hermetically-sealed construction of the present utility model has is simple in structure, be easy to manufacture and install and the advantage such as cost is low, sealing effectiveness is good, long service life, sealing effectiveness and reliability that application the utility model can significantly improve existing hermetically-sealed construction, realize good water proof and dust proof effect.Therefore, the utility model is very suitable for carrying out large-scale production and extensive use, for example can apply it to various types of electromechanical assemblies such as electric vehicle motor on.
Brief description of the drawings
Below with reference to drawings and Examples, the technical solution of the utility model is described in further detail, but it should be known that these accompanying drawings are only for task of explanation designs, therefore not as the restriction of the utility model scope.In addition, unless otherwise indicated, these accompanying drawings are only intended to Structural Tectonics described herein is conceptually described, and unnecessaryly draw to scale.
Fig. 1 is the sectional structure schematic diagram of a typical hermetically-sealed construction in prior art.
Fig. 2 is a sectional structure schematic diagram that adopts hermetically-sealed construction embodiment of the present utility model.
Embodiment
First, it should be noted that, to illustrate by way of example hermetically-sealed construction of the present utility model and be provided with concrete structure, feature and the advantage etc. of the device of sealing structure below, but all descriptions are only used for describing, and should not be understood as the utility model is formed to any restriction.In addition, in the mentioned each embodiment of this paper, described or implicit any single technical characterictic, or be shown or lie in any single technical characterictic in each accompanying drawing, still can between these technical characterictics (or its equivalent), proceed combination in any or delete, thereby obtain of the present utility model more other embodiment that may directly not mention in this article.In addition, for the purpose of simplifying drawing, identical or similar parts and feature may be only in same accompanying drawing at a place or some places indicate.
Only as an example, in Fig. 2, demonstrated the sectional structure that adopts an embodiment of hermetically-sealed construction that the utility model provides.As shown in Figure 2, in this embodiment, sealing structure comprises body and be inlaid in the framework 6 in this body, and wherein body can adopt for example rubber elastomeric material to make, and framework 6 can adopt such as metal, alloy material etc. to make to improve integrally-built rigidity.Above-mentioned body has 3 parts, i.e. Part I 1, Part II 2 and Part III 3, and wherein Part I 1 and Part II 2 are to be provided for providing sealing function, prevent that the exotics such as such as water, dust, the grains of sand from entering into sealing inside configuration.For Part III 3, it is configured to form the first space 4 between Part I 1, and and Part II 2 between form respectively second space 5, these spaces are designed to the exotic that holds those and enter into undesirably through the sealing of Part I 1, Part II 2 sealing inside configuration.
As the optional situation of one, can in above-mentioned the first space 4, second space 5, be filled into according to application needs the lubricator 7 of for example various greases and so on, thereby so as not only can to provide lastingly and stably lubrification reduce friction and extend useful life of seal member, and the exotic that enters into hermetically-sealed construction inside can be remained on to these spaces better, to these exotics are removed clean in the time carrying out regular maintenance.
In addition, although in the embodiment shown in Figure 2, Part I 1, Part II 2 and Part III 3 are shown as being configured to lip shape, but the utility model in fact also allows according to concrete application scenario in certain embodiments, they are configured to any other suitable shape.And, for Part III 3, its size can be manufactured alternatively and be less than any one size in Part I 1, Part II 2, or manufacture all less than the size of Part I 1 and Part II 2, to control thus and reduce the contact area of this Part III 3, thereby improve its durability and mar proof.
Also it is to be noted, in the utility model, for being used for holding those and entering into undesirably the space of the exotic of hermetically-sealed construction inside, its concrete position, magnitude setting, structure form etc. all can need to carry out setting flexibly according to application.
For example, in certain embodiments, two or more of Part III can be set, to form three or more spaces.And for example, can come only to form a space with above-mentioned Part I (or Part II) by a Part III.For another example these spatial configurations that formed by Part III and Part I and/or Part II can be become any suitable shape such as groove shape, hemisphere or irregular shape.Certainly, the utility model also allows in these spaces, to be filled into lubricator selectively.
Compared with existing hermetically-sealed construction, owing to having cancelled the parts that such as spring etc. is unfavorable for ensureing long term seal effect in hermetically-sealed construction of the present utility model, thereby avoid well hermetically-sealed construction to cause wearing and tearing and cause sealing effectiveness to worsen, its durability and mar proof are improved, extend useful life, and this has obtained abundant checking by test, its result shows that this hermetically-sealed construction is remarkable at the aspects such as water proof and dust proof, durability contrast effect.Therefore, be applicable to very much hermetically-sealed construction of the present utility model to be applied to needs on various types of devices and to carry out the position of encapsulation process, for example can on as the motor of all kinds of electromechanical assemblies such as motor vehicle or miscellaneous part, install one or more hermetically-sealed constructions of the present utility model, can obtain like this technique effect that is obviously better than conventional seals structure.
Below only illustrate in detail hermetically-sealed construction of the present utility model, be provided with the device of sealing structure with way of example, these a few examples are only for explanation principle of the present utility model and execution mode thereof, but not to restriction of the present utility model, in the situation that not departing from spirit and scope of the present utility model, those skilled in the art can also make various distortion and improvement.Therefore, all technical schemes that are equal to all should belong to category of the present utility model also by every claim of the present utility model is limited.
