A kind of damping device
The utility model relates to a kind of damping device, specifically a kind of controller damping device.
No matter be traditional fuel vehicle or new energy mixed power or pure electric automobile, control apparatuss such as entire car controller or electric machine controller all are installed in the car.During installation, controller directly and vehicle frame be rigidly connected, owing to can produce significantly vibrations in the vehicle driving, these vibrations are directly conducted to controller by vehicle frame, the vibration environment of car load is that amplitude of vibration is when surpassing controller and limiting shock value, can have a strong impact on controller proper functioning and working life, reduce its functional reliability, even bring potential safety hazard.
Traditional damping device generally is with bolt cylindrical or conical rubber pad to be directly installed on the controller bottom, or use the bolt that is with rubber pad controller to be fixed on the vehicle frame by mounting bracket, by rubber pad controller and vehicle frame are separated, become soft connection by being rigidly connected, when cross-car or when vertically shaking, rely on the elastic strain of rubber pad self can effectively reduce the conduction of vibrations.Vehicle is at road traveling, and controller is subjected to mostly is vibrations on its Vertical direction, because the elastic strain of rubber column or rubber pad self is limited, so its ability that absorbs the vibrations of controller Vertical direction is also very limited.
The model utility content
This practical new purpose is in order to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy for installation, reliability is high, can effectively reduce the car body vibrations influence to controller, the damping device that prolongs its working life, its ability that absorbs the vibrations of controller Vertical direction is strengthened, improve the ability of bearing load.
The utility model solves its technical problem and takes following scheme to realize:
A kind of damping device comprises snubber block, it is characterized in that: described snubber block is hollow runway shape column structure, has the mounting hole with this lateral vertical on two parallel sides.
Described snubber block mounting hole is embedded with anti-rotation screw hole mold insert.
The material of described snubber block is an elastic material.
Also can comprise the mounting bracket that has mounting hole.
When using damping device of the present utility model, link to each other with vehicle frame with controller pass the screw hole of snubber block both sides respectively with two bolts or screw after, be controller with vehicle frame between be connected by the elastic shock attenuation piece, the snubber block of hollow runway shape is equivalent to a rubber spring, the ability that absorbs the Vertical direction vibrations significantly improves, and the ability of bearing load is stronger.
The snubber block mounting hole is embedded with anti-rotation screw hole mold insert, and is simple in structure, assembles more firmly, can avoid because the bolt looseness that causes of jerk and the damage of snubber block mounting hole.
The attachment face of snubber block is the plane, and can fully fit corresponding fitting plane or mounting bracket can transmit the suffered impact force of car body equably, avoids snubber block to deflect even ftractures, thereby prolong working life of whole damping device, saves cost.
Description of drawings
Fig. 1 is the utility model damping device structural representation.
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.As shown in Figure 1,
Wherein 1 is screw, and 2 is packing ring, and 3 is mounting bracket, and 4 is anti-rotation screw hole mold insert, and 5 is snubber block.The damping device of present embodiment, comprise screw 1, packing ring 2, mounting bracket 3, snubber block 5, described snubber block 5 are hollow runway shape column structure, i.e. the loop configuration of being made up of the two parallel rectangular cylinder arc cylinders relative with two, have the mounting hole vertical with this cylinder on two parallel cylinders, the direction of mounting hole is consistent with plane, two cylinder places.The mounting hole of snubber block 5 is embedded with anti-rotation screw hole mold insert 4, and anti-rotation screw hole mold insert 4 is selected metallic material for use in the present embodiment, and the mold insert upper surface is hollow runway shape, makes it keep enough intensity and difficult generation deformation or displacements when mounted.Snubber block 5 adopts the rubber-like rubber material, cooperates its hollow runway structure can more effectively reduce vibrations, improves load-carrying ability.
The damping device of present embodiment comprises mounting bracket 3, by mounting bracket 3 snubber block is connected to controller and vehicle frame, mounting bracket 3 can be independently " one " font or " L " shape, forms mounting hole on the mounting bracket 3, and mounting bracket also can be the part on controller or the vehicle frame.
When using damping device of the present utility model, be inserted in packing ring with bolt or screw, pass the mounting hole on the corresponding mounting bracket respectively, the metal inserted piece screw hole that penetrates the snubber block both sides is again tightened fixing, is connected on controller and the vehicle frame by another mounting hole on the mounting bracket.Concrete installation conditions and vehicle operating environment according to controller, can select to be provided with the number of this damping device, select for use four groups of damping devices to be connected the controller both sides in the present embodiment by " L " type mounting bracket, transfer the soft connection that connects by damping rubber block to by traditional direct rigid connection between controller and the vehicle frame, hollow runway shape snubber block with curved guide is equivalent to a rubber spring, can absorb the vibrations of the Vertical direction that car body receives better, the ability of bearing load is stronger.
In sum, by adopting damping device of the present utility model, effectively improved the ability that absorbs the car body Vertical direction vibrations that controller is subjected to, the controller shock resistance is better, have also obtained effective raising in its working efficiency and working life.
