Abstract
The utility model discloses an electric fuel pump vibration damper with a good vibration damping effect, which comprises a bracket. Elastic supports are arranged on the periphery of the bracket; the elastic supports comprise connecting rods and elastic clips; the tail ends of the elastic clips are provided with elastic bosses; and balance weights are arranged in the bracket. Under the action of the elastic supports, a multidirectional elastic constraint force can be provided by the vibration damper to take the better vibration damping action. The electric fuel pump vibration damper provided in the utility model has a simple structure, is convenient to use and can be used for providing the multidirectional elastic constraint force to take a better vibration damping effect.
Description
Technical field
The utility model relates to a kind of auto parts and components, and in particular, the utility model relates to a kind of electric fuel punp vibration damping equipment.
Background technique
At present, for the car that adopts electric fuel punp, provide fuel oil by the rotation of fuel pump motor internal work impeller to motor, during motor rotation, the radiated noise that the fuel pump vibration causes the fuel tank vibration to produce influences the internal car noise level.
The Chinese patent notification number is CN201568176U, notice of authorization day is on September 01st, 2010, the name of model utility is called electric fuel pump bracket, this application case discloses a kind of electric fuel pump bracket, comprise: bracket, bottom bracket, electric fuel punp is installed in the inside of bracket and bottom bracket, assembles connection mutually by buckle structure between the upper and lower carriage, provide jointly to electric fuel punp radially with axial constraint; The inlet port of electric fuel punp and the filler opening of bottom bracket cooperatively interact; Bracket is provided with the circlip structure of ring-type, and the circlip structure of bracket has downward elastic restraint power in the upper end of electric fuel punp to electric fuel punp.Wherein deficiency is the elastic restraint power that only provides unidirectional, and vibration damping is not ideal enough.
Summary of the invention
The purpose of this utility model is to solve above-mentioned unidirectional elastic restraint power is provided, and the dissatisfactory problem of vibration damping provides a kind of electric fuel punp vibration damping equipment of good damping result.
For realizing above purpose, the technical solution of the utility model is a kind of electric fuel punp vibration damping equipment, comprise carriage, it is characterized in that described bracket perimeter is provided with elastic support, described elastic support comprises connecting rod and elastic clip, described elastic clip end is provided with the elasticity boss, described carriage inside is provided with counterweight member, and described connecting rod is fixedlyed connected with elastic clip, and described elastic support is fixedlyed connected with carriage.This vibration damping equipment can provide multidirectional elastic restraint power under the effect of elastic support, played better damping effect, counterweight member has increased the weight of vibration damping equipment, can alleviate the vibration of fuel pump, the elasticity boss is stuck on the fuel pump bracket, conveniently fixes this vibration damping equipment.
As preferably, at least three of described elastic supports.At least three of elastic supports in when vibration, can prevent the position deflection of vibration damping equipment, better fixing electric fuel punp vibration damping equipment.
As preferably, the counterweight ring of described counterweight member for being complementary with carriage.Counterweight member is the counterweight ring that is complementary with carriage, can evenly increase the weight of carriage, prevents the problem of centre-of gravity shift.
As preferably, described elasticity boss is rounded.The elasticity boss is rounded, conveniently processing elasticity boss mounting hole on the electric fuel punp support.
As preferably, be socket between described carriage and the elastic support.Be socket between carriage and the elastic support, parts do not have matching gap as a whole, have better played effectiveness in vibration suppression, are easy to change yet.
The utlity model has following beneficial effect: simple in structure, easy to use, multidirectional elastic restraint power can be provided, can play better effectiveness in vibration suppression.
