Description
Technical field
The utility model is related to electronic strut technical fields, are related specifically to a kind of ball cup for electronic strut.
Background technology
The unlatching tradition of automobile tail gate is manually opened tail-gate after being unlocked by driver, is connected by pneumatic rod or four
What bar hinge or gooseneck hinge cooperation torsion-bar spring were realized.In domestic existing automobile, generally connected using pneumatic rod or four
Bar hinge or gooseneck hinge cooperation torsion-bar spring, the only vehicle of high gauge use electric tail gate, are by electronic strut reality
Existing.
And the electronic strut overwhelming majority includes outer tube and the inner tube being slidably matched with outer tube, and drive is internally provided in outer tube
The transmission mechanism that inner tube is slided along its axial direction is equipped with the motor for driving transmission mechanism in the bottom of outer tube, before inner tube
End and the bottom end of outer tube are respectively equipped with and are arranged on the matched ball cup of stent bulb on automobile tail gate and body of a motor car, from
And automobile tail gate can be made to automatically turn on or close under the action of motor and transmission mechanism.
The ball cup overwhelming majority that the prior art is arranged on the front end of inner tube is split type, and split type ball cup is general
It is completed using mechanical processing techniques such as turnning and millings, as shown in Figure 1, split type ball cup 10 includes pedestal 101 and bulb 102,
One end that pedestal 101 is used to install bulb 102 is equipped with through-hole, is opened up in one end that bulb 102 is used to be installed on pedestal 101
There is a threaded hole, during installation, through-hole with threaded hole is aligned, screw 104 is then each passed through sealing ring 103, through-hole and screw thread
Hole coordinates, and so as to which bulb 102 is fixedly mounted on pedestal 101, can bring the following insufficient using the above structure：1. it uses
The production efficiency of mechanical processing technique is relatively low；2. need that pedestal and bulb be connected as an entirety by connector, efficiency of assembling compared with
It is low；3. ball cup is divided into two parts, so as to make the leakproofness of ball cup poor.
However in view of the deficiencies of the prior art, it is necessary to develop a kind of reasonable design, simple in structure, production efficiency by developer
High, at low cost, ball cup be an entirety, the ball cup for electronic strut of good seal performance.
Utility model content
Of the existing technology to solve the problems, such as, the utility model aim provides a kind of reasonable design, simple in structure, raw
Efficient, at low cost, ball cup is produced as an entirety, the ball cup for electronic strut of good seal performance.
For solution more than technical problem, what the utility model was realized using following technical scheme：
A kind of ball cup for electronic strut, the ball cup ontology of the front end including being arranged on inner tube, which is characterized in that
The ball cup ontology is integrally formed using microdiecast, the ball cup ontology include whole cylindrical pedestal and with seat
The bulb that body is integrally formed, the bulb are arranged on one end of pedestal, are equipped on the inner surface of the other end of the pedestal
With the matched internal thread of external screw thread being arranged on the peripheral surface of feed screw nut front end.
In a preferred embodiment of the utility model, on the peripheral surface in the middle part of the pedestal be equipped with be arranged in
The matched annular groove of interior male structure of pipe front end.
In a preferred embodiment of the utility model, the annular groove and pedestal are coaxial.
In a preferred embodiment of the utility model, it is equipped on the peripheral surface of the front end of the pedestal with being arranged on
The matched annular slot of annular card base on sealing shroud.
In a preferred embodiment of the utility model, the annular slot and pedestal are coaxial.
Compared with prior art, the utility model has the following advantages using the above structure：
1. ball cup is integrally formed using microdiecast, the production efficiency of ball cup is effectively raised；
2. avoiding that bulb is mounted on pedestal using connector, the installation process of bulb and pedestal is omitted, effectively
Reduce the cost of production and management；
3. ball cup is an entirety, the sealing performance of ball cup is effectively raised.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
