Go out；（2）Since Decorative Cover support base does not have the position limiting structure of rubber sleeve, rubber sleeve assembling cannot be effectively ensured in place, cause
The slot opening of ball stud and rubber gum cover misplaces, and causes assembling difficult；（3）The diameter dimension of the ball head of ball stud with
The diameter dimension on neck top is close, to avoid excessively causing assembling difficult with rubber sleeve interference at the neck of ball stud,
The slot opening size of rubber sleeve cannot design too small, and the limit effect of ball stud is bad, in engine luggine, bulb
Bolt is easily deviate from.
The content of the invention
The purpose of this utility model is to provide a kind of automobile engine trim cover and the connection structure of cylinder head cover, with effectively anti-
Only rubber sleeve is deviate from, while is more convenient connection.
The connection structure of automobile engine trim cover described in the utility model and cylinder head cover including rubber sleeve, is located at dress
Decorations cover the Decorative Cover support base of lower surface and the ball stud being fixedly mounted on cylinder head cover, are offered in the rubber sleeve recessed
Slot, the ball head of the ball stud are connected in the groove, and the Decorative Cover support base includes side wall and lower end is open
Supporing shell, the top plate that is located at the bottom plate of supporing shell lower end and is located in the middle part of supporing shell inner wall, top plate is parallel with bottom plate,
It is and vertical with the axis of supporing shell；The outer wall of rubber sleeve shape in a manner that interval opens up first, second annular slot
Into there is first, second, third round platform；Offer shape of reverse omega notch on the bottom plate, the supporing shell inner wall lower be equipped with
Bottom plate parallel reinforcing plate offers U-shaped breach in reinforcing plate, the first limit chamber, reinforcing plate is formed between reinforcing plate and top plate
The second limit chamber is formed between bottom plate；The rubber sleeve is installed to Decorative Cover support base at the sidewall opening of supporing shell
On, the first round platform is located in the first limit chamber, and the second round platform is located in the second limit chamber, and reinforcing plate passes through U-shaped breach and first
Annular slot is clamped, and realizes reinforcing plate and the interference fit of first annular card slot, and bottom plate passes through shape of reverse omega notch and the second annular
Card slot is clamped, and realizes the interference fit of bottom plate and the second annular slot.
The distance of upper surface of the upper surface of first round platform to the 3rd round platform and the lower surface of the top plate to bottom plate
Lower surface distance it is equal, when rubber sleeve is installed on Decorative Cover support base, under the upper surface and top plate of the first round platform
It pastes on surface zero（I.e. patch is dead）, the upper surface of the 3rd round platform and the lower surface zero of bottom plate are pasted（I.e. patch is dead）, rubber sleeve is in Decorative Cover branch
The fixed effect supportted in seat is more preferable.
The ratio of the diameter of the ball head of the ball stud and the diameter on neck top is 2:1, the groove of rubber sleeve is opened
The smaller that mouthful size can design, it is apparent to the limit effect of ball head, when can effectively prevent engine luggine ball stud from
Deviate from rubber sleeve.
The utility model has the following effects that：
（1）/V is carried out to first, second round platform using first, second limit chamber, reinforcing plate passes through U-shaped breach and first
Annular slot is clamped, and bottom plate is clamped by shape of reverse omega notch and the second annular slot, and rubber sleeve is made to be securely fixed in Decorative Cover
On support base, rubber sleeve will not be deviate from out of Decorative Cover support base.
（2）After rubber sleeve is assembled on Decorative Cover support base, the slot opening position of rubber sleeve is it has been determined that ball stud fills
Timing is not in misplace with the slot opening of rubber sleeve, easy to assembly.
（3）The design of the ball head of ball stud and the diameter dimension ratio on neck top, effectively prevents engine
Ball stud is deviate from from rubber sleeve during vibration.
