Embodiment
Core of the present utility model provides a kind of diesel exhaust aftertreatment controller, for reducing the cost of diesel exhaust aftertreatment controller, and improves its sealing property.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1 to Fig. 6, at the diesel exhaust aftertreatment controller that the utility model embodiment provides, comprise upper casing 1 and connector module 2, upper casing 1 comprises again and the connector port 3 of upper casing 1 integrated injection molding that connector module 2 is plugged in connector port 3.
Because outsourcing connector cost is higher, therefore connector is carried out the split design, make connector port 3 and upper casing 1 integrated injection molding, design can reduce the cost of connector greatly like this, save the fitting tight of connector and upper casing 1 simultaneously, improved water resistance.
Because upper casing 1 is plastic casing, the bonding strength of considering plastic casing is relatively poor, so embed in upper casing 1 metal insert 9 is arranged, controller is connected with outside mounting interface by metal insert 9, and metal insert 9 just can increase the bonding strength of entire controller and outside mounting interface effectively.
Also be embedded with nut 10 in the upper casing 1, screw 5 is threaded with nut 10, thereby upper casing 1 and lower casing 4 are fixed together, nut 10 can guarantee between upper casing 1 and the lower casing 4 be connected fastening reliably.
In order to reduce the height of controller, the present embodiment scheme has been carried out the step design to upper casing 1, namely be provided with step end face 11 and step bottom surface 12 at upper casing 1, step end face 11 is higher than step bottom surface 12, higher electronic device is placed on the step end face 11 following corresponding circuit boards 6, and connector port 3 is placed on the step bottom surface 12, such step design can well reduce the height of controller.
In order to improve the resistance to shock of controller, be provided with cushion blocking 8 at the drift angle place of upper casing 1.The structure of cushion blocking 8 mainly is to cooperate according to its containing with upper casing 1 each end angle to design, the shape and structure of each cushion blocking 8 can be the same, appoint and to get a cushion blocking 8 and can be assemblied on each end angle of housing, so both can improve efficiency of assembling, and can make cushion blocking 8 have versatility and interchangeability again.
The periphery design of upper casing 1 has the convex tendon 14 of certain altitude and width, the periphery of lower casing 4 and the design of convex tendon 14 corresponding positions have corresponding groove, before upper casing 1 fastens with lower casing 4, in lower casing 4 peripheral corresponding recesses, apply a certain amount of fluid sealant 15, then upper casing 1 and lower casing 4 are fastened, with specific frock lower casing 4 is carried out precompressed, use screw 5 that upper casing 1 and lower casing 4 is fastening at last.
As shown in Figure 5, it needs to be noted, be used for upper casing 1 and the fluid sealant 15 of lower casing 4 sealings have been extended to the periphery of circuit board 6, fluid sealant 15 just can bond together upper casing 1, lower casing 4, circuit board 6 simultaneously, therefore, when playing the device waterproof action that tightens control, also strengthened the be connected effect of circuit board 6 with upper casing 1.
In order to improve the heat dispersion of controller, the lower casing 4 in the present embodiment scheme adopts the sheet stamping of metal material to form.In main heat dissipation region, namely the inner surface place of the lower casing 4 of the high power device correspondence on the circuit board 6 applies a certain amount of thermal paste, and the heat that is produced by the high power device on the circuit board 6 just can well distribute by thermal paste and metal lower shell 4.
To be connected firmly, to reduce cost in order to make and improve efficiency of assembling, circuit board 6 in the present embodiment scheme adopts the mode of hot riveting to fix with upper casing 1, as shown in Figure 4, fabric swatch situation according to electronic device on the circuit board 6, set in advance the rivet hot post 16 of respective numbers at the inner surface of upper casing 1, after circuit board 6 and upper casing 1 assembling, disposable or rivet hot post 16 is riveted with specific rivet hot machine in batches, make circuit board 6 and upper casing 1 solid and reliable being fixed together.
As shown in Figure 6, this mistake proofing structural design mainly realizes by two aspects: the one, and spacing B and the A of the screw 5 of lower casing 4 the right and lefts do not wait, if misloading, screw 5 can't be thrown in the nut 10; The 2nd, the side design of lower casing 4 has projection 17, and 17 places are provided with the gusset that matches with protruding 17 shapes in upper casing 1 respective protrusions, have only correct placement upper casing 1 and lower casing 4 to assemble, so can how directed from visually judging this in advance when assembling.The present embodiment scheme has been taked above-mentioned two kinds of mistake proofing structural designs, certainly, also can select other forms of mistake proofing structure for use.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
