DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

(9) To achieve the aforementioned objective and effects, with regards to the technical means and structures utilized in the present invention, the structures and functions thereof will be hereunder set forth by the details descriptions concerning the preferred embodiments of the present invention along with appended drawings in order to facilitate comprehensive appreciation of the present invention.

(10) Refer to FIGS. 1, 2, 3, 4, 5, 6, 7 and 8, wherein a stereo perspective view, a stereo perspective view from another angle of view, a lateral cross-section view, a stereo disassembly view for a preferred embodiment before assemblage, a stereo disassembly view before assemblage from another angle of view, a stereo perspective view in assemblage, a stereo perspective view after assemblage and a stereo perspective view after assemblage from another angle of view according to the present invention are respectively shown. From the Figures, it can be clearly seen that the admission pipe structure for automobile air admission according to the present invention comprises an admission pipe 1 which includes an arc-shaped pipe body 11 turning first downwardly then upwardly, and a hollow channel 10 is formed inside the pipe body 11, an admission hole 101 and an exit hole 102 are formed on two sides of the channel 10, then an exhaust recycle connector 111 connected to the inside of the channel 10 is installed on the outer surface of the pipe body 11 near the central section, a first sleeve connection part 12 and a second sleeve connection part 13 are respectively installed at the admission hole 101 and the exit hole 102 of the admission pipe 1, and a position-limiting ring groove 121 having an enlarged diameter of hole for positioning a leakage blocking ring 122 is installed in recess on the first sleeve connection part 12 from the periphery of the admission hole 101 toward the direction of the channel 10. Meanwhile, an accommodation groove 131 having an enlarged diameter of hole for positioning an O-shaped ring 132 is installed in recess on the second sleeve connection part 13 from the periphery of the exit hole 102 also toward the direction of the channel 10, and then an abutting face 1311 is formed on the bottom of the accommodation groove 131 adjacent to the channel 10.

(11) Moreover, at least two through-grooves 14 connected to the inside of the channel 10 are installed in cut on the outer surface of the second sleeve connection part 13 of the admission pipe 1, and the inner wall surfaces of the two neighboring through-grooves 14 both include a tilted stopping face 141. Also, a buckling component 15 is installed in penetration within the two through-grooves 14 of the admission pipe 1, an arch-shaped pull ring 1511 is formed at the center of a base part 151 included in the buckling component 15 thereof, and two sides of the base part 151 extend outwardly to form a relative elastic part 152 and an arc-shaped buckling part 153. In addition, the two elastic parts 152 bend inwardly adjacent to the base part 151 to form clamping arms 1521, and then respectively turn outwardly to extend and form a stopping ring 1522, while the ends of the two buckling parts 153 form abutting ends 1531 turning outwardly.

(12) The admission pipe 1 according to the present invention may be installed between a central cooler 2 of the turbo charging system in an automobile (e.g., a car) and the regulation throttle (not shown) at an admission manifold pipe 3 or the front end of the admission manifold pipe 3 of an engine, and may be connected to the air outlet of the turbo by way of an admission connector 21 of the central cooler 2. When the exhaust air of high temperature and high speed released during the operation of the engine flows into the turbo at the exhaust side, the inertial thrust of the exhaust may push the turbo in the turbo chamber to rotate and the turbo may co-axially drive the fan wheel to rotate simultaneously so as to forcibly compress the entering air by means of the fan wheel. Also, the compressed air having dramatically increased temperature passes through the internal heat-sinks of the central cooler 2 to cool down thus becoming the compressed air having a certain pressure and high density, and the lower oxygen contents in the compressed air may accordingly elevate, then flowing through an exit connector 22 of the central cooler 2, the admission pipe 1, the regulation throttle and the admission manifold pipe 3 to enter into the engine cylinder for combustion. As the engine rotation speeding up, the exhaust release speed and the turbo rotation speed may also accelerate at the same time, so the fan wheel may compress more air thus controlling the flow speed of the compressed air entering into the engine cylinder via the admission manifold pipe 3 cooperatively by means of the regulation throttle. Besides, since the increased pressure and density of the compressed air may burn more fuel, it is possible to correspondingly augment more fuel amount and improve the combustion efficiency inside the engine cylinder thereby achieving the objective of enhanced engine output power.

(13) To assemble the present invention, the leakage blocking sleeve ring 122 of the admission pipe 1 is first latched into the position-limiting ring groove 121 of the first sleeve connection part 12, and the first sleeve connection part 12 is placed in alignment to the exit connector 22 of the central cooler 2 by means of the admission hole 101 of the pipe body 11. Next, the first sleeve connection part 12 is sleeved onto the exit connector 22 thus allowing the exit connector 22 to penetrate and abut closely to an inner wall face of the leakage blocking sleeve ring 122 for fixedly positioning such that a sealed state can be created between the exit connector 22 and the first sleeve connection part 12 of the admission pipe 1. Following this, the O-shaped ring 132 is latched into the accommodation groove 131 of the second sleeve connection part 13, and the second sleeve connection part 13 is placed in alignment to an admission connector 31 of the admission manifold pipe 3 by means of the exit hole 102 of the pipe body 11 thereby sleeve connecting the second sleeve connection part 13 onto the admission connector 31 and placing in alignment the two through-grooves 14 of the second sleeve connection part 13 to a ring-shaped groove 311 on the outer surface of the admission connector 31. Moreover, due to the squeeze effect from the admission connector 31, the O-shaped ring 132 can abut against the abutting face 1311 of the accommodation groove 131 to exhibit an elastic transformation, thus creating a sealed state between the second sleeve connection part 13 and the admission connector 31.

(14) Subsequently, the two buckling parts 153 of the buckling component 15 can respectively penetrate into the corresponding through-groove 14 on the second sleeve connection part 13, and the abutting end 1531 of the buckling part 153 can go through the through-groove 14 and abut against the ring-shaped groove 311 of the admission connector 31. Moreover, under the effect of the reverse push force from the ring-shaped groove 311, the buckling part 153 may create an outward elastic transformation by using the elastic part 152 as a supportive point, and the two elastic parts 152 may, through the elastic transformation and restoration, relatively and inwardly clamp onto the stopping faces 141 of the two through-holes 14 by means of the clamping arm 1521. Furthermore, the stopping ring 1522 may be latched into the ring-shaped groove 311 of the admission connector 31 and the abutting end 1531 of the buckling part 153 may abut against the inside of the ring-shaped groove 311 such that the buckling component 15 can be axially blocked to an abutting face 3111 on the inner wall of the ring-shaped groove 311 for fixedly positioning, thus the second sleeve connection part 13 of the admission pipe 1 may not easily fall out from the admission connector 31 of the admission manifold pipe 3 thereby enabling stable restricting and positioning functions as well as a retreat-blocking feature. This type of buckling component 15 can facilitate more convenient assemblage of the admission pipe 1 and the admission manifold pipe 3 for users and ensure stability in the integral structure.

(15) When the compressed air outputted by the central cooler 2 goes into the admission hole 101 located on one side of the admission pipe 1 by way of the exit connector 22, it can be well guided by the arc-shaped channel 10 in the pipe body 11 such that the compressed air can flow smoothly without undesirable blockage or stocking issues, and, after rapidly leaving via the exit hole 102 on the other side of the admission pipe 1, it flows through the regulation throttle and the admission manifold pipe 3 and enters into the engine cylinder for combustion so as to accelerate the flow speed of the compressed air entering into the engine cylinder thereby correspondingly increasing the amount of fuel and enhancing the combustion efficiency and output power in the engine cylinder. Also, under the squeeze effect, the O-shaped ring 132 may demonstrate an elastic transformation such that the O-shaped ring 132 can completely seal minor or tiny fissures possibly existing between the second sleeve connection part 13 and the admission connector 31 in order to generate the leakage blocking feature. This type of admission pipe 1 may be made of aluminum alloy materials and the arc-shaped structural design of the pipe body 11 can well guide the compressed air so as to prevent undesirable conditions, e.g., airflow turbulences or strays of the compressed air within the channel 10, such that the compressed air may travel stably and smoothly and noises caused by airflow turbulences may be reduced as well. Moreover, the aluminum alloy materials contained in the admission pipe 1 itself can provide good structural strength thereby preventing damages to the structure as the compressed air flowing through at high speed as well as durability. Besides, the properties of higher coefficients of heat conductions and fast heat dissipation offered by the aluminum alloy materials in the admission pipe 1 can also lower the temperature of the compressed air when passing through the channel 10 so as to reduce the pressure losses. In addition, the lowered admission temperature of the compressed air may also relatively increase the oxygen contents therein so as to enable better combustion efficiency as the compressed air being fast released and entering into the engine via the regulation throttle and the admission manifold pipe 3, thus allowing to correspondingly add greater amount of fuel such that the output power of the engine can be significantly improved.
