Detailed Description

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the present invention provides an electric control box capable of significantly improving the stability of assembling contact and significantly reducing noise. The electronic control box comprises a box body 1, the electronic control box further comprises a box cover 2 and a fixing component, and the box cover 2 is connected to the open side face of the box body in a covering mode in an elastic mode under the matching of the fixing component. The technical scheme that this application provided changes the lid through the basis at present box body to increase fixed subassembly, then will the lid elastic lid under the cooperation of fixed subassembly connect on the open side of box body. Therefore, the electronic control box cover can be ensured to be continuously and well contacted with the electronic control box body, even if the electronic control box cover can be kept in good contact under the vibration effect transmitted by other parts, and meanwhile, the problem that the electronic control box cover generates vibration noise due to vibration can be effectively solved due to good contact.

In the above-mentioned embodiment, the box body 1 that combines current automatically controlled box is for being the structural feature that the metal sheet that is usually had connection turn-ups 3 buckles the box body to and the lid leads to the situation that also has the dismouting turn-ups, and this application provides the fixed subassembly of two kinds of structures. The utility model provides a fixed subassembly is for including connecting bolt 4 and elastic buffer, and lid 1 that has a dismouting turn-ups 5 passes through connecting bolt 4 and elastic buffer elastic lid connect on the open side of box body, dismouting turn-ups 5 connect on connecting turn-ups 3 towards the lid of box body one side. At this time, the elastic buffer is preferably a buffer spring sleeved on the connecting bolt on the side where the dismounting flange 5 is not arranged. Another kind of fixed subassembly include connecting bolt 4 and the elasticity of setting on lid 2 is pegged graft perk 6, lid 2 a dismouting turn-ups 5 has, elasticity peg graft perk 6 set up and serve not arranging dismouting turn-ups 5, be provided with grafting convex hole 7 on the connection turn-ups 3 of box body 1, be provided with bolt hole 8 on dismouting turn-ups 5 and the connection turn-ups 3 of the one side that does not set up grafting convex hole 7, lid 2 respectively through the cooperation of elasticity grafting perk 6 and grafting convex hole 7 and bolt hole 8 and connecting bolt 4's the elastic lid of cooperation connect on the open side of box body.

Further, in order to improve the stability of the connection structure, two elastic insertion perks 6 are arranged at one end of the box cover 2 where the disassembly and assembly flanging 5 is not arranged, and the number and the positions of the insertion convex holes 7 arranged on the connection flanging 3 of the box body 2 are adapted to the number and the positions of the elastic insertion perks 6. Simultaneously, in order to make automatically controlled lid do not have the screw fixation one end and continuously well contact with automatically controlled box, need better control part deformation state and deflection, otherwise the easy contact unstability that appears to the vibration that leads to automatically controlled lid to appear vibration noise's problem because of the vibration of other part transmissions. In addition, the fit clearance of the insert buckle structure is too small, so that the assembly operation is inconvenient, and in the buckling process, the part is seriously deformed locally to influence the fit effect of the part.

Certainly, in order to facilitate wire passing, a wire passing groove 9 is further formed in the side wall of the box body 1.

In summary, the electric control box provided by the application also has the following advantages,

the fixed one end of automatically controlled lid checkpost promptly the above-mentioned form that is provided with elasticity grafting perk one end designs into the higher crooked dysmorphism structure of intensity, and in the square hole of automatically controlled box was assembled in the insertion that can be more convenient, the fixed back of screw fastening end, the effective contact of fixed and sheet metal component of realization that can be better promoted the stability of structure cooperation effect and electromagnetic shield effect. The requirement for reducing the deformation degree of the part is met, the qualification rate of the part is improved, and the reliability of fixed contact can be improved.

1. The control requirement on the deformation effect of the part is reduced, the contact stability of the electric control box cover and the electric control box at one end without the screw fixation is improved, and the influence of vibration on the contact effect is reduced.

2. Through structural configuration design adjustment, adapt to actual assembly operation custom, reduce the operation degree of difficulty. DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
