Description
Technical field
The utility model is related to automotive fields, and in particular to a kind of electronic device.
Background technology
In electronic device, such as automobile instrument, in order to ensure that instrument can safely and reliably work, would generally be set on housing
Longer sealing element is put, to ensure the leakproofness of instrument.
As shown in Figure 1, instrument includes housing, translucent cover 2 and pcb board (not shown), housing includes front wall 1 and is used for
The front frame 3 translucent cover 2 being installed in front wall 1, is provided with sealing element 4 between front frame 3 and front wall 1, panel 2.
In order to ensure the leakproofness of instrument, sealing element 4 uses profile seal part, and sealing element 4 includes the peace of embedded mounting groove
Dress portion 41.
In the assembling process of instrument, pcb board is installed in front wall 1 first, translucent cover 2 is secondly installed to front wall 1
On, then the mounting portion 41 of sealing element 4 is embedded between front wall 1, translucent cover 2 in mounting groove, is finally pressed into front frame 3 close
On sealing 4, and the edge of front frame 3 is folded inward in the edge of front wall 1.
In above process, since sealing element 4 is longer, on the one hand installation is more time-consuming by hand, if on the other hand close
Sealing 4 is installed not in place, can cause the poor sealing of instrument, it is possible to influence the normal work of instrument.
Utility model content
For problems of the prior art, problem to be solved in the utility model is to provide a kind of electronic device, shell
The metalwork or plastic article of body form composite members with sealing element by vulcanization, can either ensure the leakproofness of electronic device, so as to
Ensure that electronic device safely and reliably works；Installation work-hour can be shortened again, improve the production efficiency of electronic device.
The utility model provides a kind of electronic device, including housing, sealing element and the pcb board being set in housing, shell
Body includes metalwork or plastic article, and metalwork or plastic article form composite members with sealing element by vulcanization.
Further, sealing element is rubber parts.
Further, it is convex surface for the surface of sealing on sealing element.
Further, it is curved surfaces for the surface of sealing on sealing element.
Further, electronic device is instrument.
Further, metalwork is front frame, and housing further includes front wall, and instrument includes translucent cover, and front frame is formed with sealing element
Composite members, composite members are for front wall and translucent cover to be fastened.
Compared with prior art, electronic device provided by the utility model, has the advantages that：The metalwork of housing
Or plastic article forms composite members with sealing element by vulcanization, can either ensure the leakproofness of electronic device, so as to ensure that electronics fills
It puts and safely and reliably works；Installation work-hour can be shortened again, improve the production efficiency of electronic device.
Description of the drawings
Fig. 1 is the schematic diagram of instrument in the prior art；
Fig. 2 is the partial schematic diagram before the front frame installation of the instrument of one embodiment of the utility model；
Fig. 3 is the partial schematic diagram after the front frame installation of instrument shown in Fig. 2.
Specific embodiment
As shown in Fig. 2, the instrument of one embodiment of the utility model, (does not show including housing, translucent cover 2 and pcb board
Go out), housing includes front wall 1 and for translucent cover 2 to be installed to the front frame 5 in front wall 1, front frame 5 and front wall 1, translucent cover 2 it
Between be provided with sealing element 6.
In the present embodiment, front frame 5 uses metalwork.
Sealing element 6 is rubber parts.
In polymer chemistry, vulcanization (Vulcanization) refers to rubber size by raw rubber intermolecular cross-linking, raw
Into the process of the vulcanizate with three-dimensional net structure.
Rubber can be bonded by sulfurization with metal, and concrete operations are as follows：The inner surface of front frame 5 (is used for solid
Determine the part of sealing element 6) it is surface-treated, including degreasing, cleaning etc., adhesive is then coated with, front frame 5 is put into mold,
The rubber size melted from material hole injection, is put into vulcanizing press and is vulcanized, form front frame 5 (metalwork) and sealing element 6
Composite members.
Through over cure, sealing element 6 is fixed together with front frame 5, and when installation no longer needs mounting groove, therefore this implementation
It no longer needs to design mounting groove in example, in the structure of translucent cover 2 and front wall 1, simplifies the structure of translucent cover 2 and front wall 1.
In assembling, as shown in figure 3, the composite members of front frame 5 and sealing element 6 directly are pressed into translucent cover 2 and front wall 1
On, and fold inward the edge of front frame 5 in the edge of front wall 1, it can either ensure the leakproofness of instrument, so as to ensure instrument
Safely and reliably work；Installation work-hour can be shortened again, improve the production efficiency of instrument.
The surface that sealing is used on sealing element 6 is convex surface, can better ensure that leakproofness in this way, be sealed in the present embodiment
The surface that sealing is used on part 6 is curved surfaces.
Certainly in other examples, the plastic article in housing can also be glued by the sealing element vulcanized with rubber material
It connects, so as to not only ensure that the leakproofness of housing, but also long sealing ring need not be installed by hand, improves production efficiency.
But in this scheme, it is high intensity that plastic article needs in itself, heat safe.
Although the utility model has been disclosed in the preferred embodiments as above, the utility model is not limited to this.Any
Field technology personnel, the various changes made without departing from the spirit and scope of the utility model and modification, should all be included in this
In the protection domain of utility model, therefore the scope of protection of the utility model should be subject to claim limited range.
