In this embodiment, during the use of the exhaust duct assembly 10, the first air duct 11 and the second air duct 12 are disposed vertically, and the second air duct 12 is sleeved outside the vehicle exhaust duct 22 through the anchor ear 15. Because the direction of the bumping acting force generated during the running of the vehicle and the extending direction of the first air duct 11 are in an inclined relation, the second air duct 12 bears asymmetric load, and the stress is concentrated, so that the second air duct 12 above the hoop 15 is easily damaged. In order to solve the above-mentioned problems, the present invention provides an exhaust barrel assembly 10, as shown in fig. 1,2, 3, 4 and 5, the exhaust barrel assembly 10 includes a first air guide barrel 11, a second air guide barrel 12 and a hoop 15.
The axis of the first air duct 11 is perpendicular to the axis of the second air duct 12. One end of the first air duct 11 is communicated with one end of the second air duct 12 to form a continuous exhaust channel, so that smooth air flow discharged by the vehicle is ensured. The end of the second air duct 12 far away from the first air duct 11 is an assembly end. The anchor ear 15 is sleeved outside the assembly end for being sleeved outside the exhaust pipe 22 of the vehicle. The fastening force is provided by the anchor ear 15, so that the stable installation of the assembly end is ensured. And meanwhile, the second air duct 12 and the exhaust pipe 22 can be quickly connected, so that the disassembly and the maintenance are convenient.
The second air duct 12 has a first side and a second side distributed along its circumferential direction, the first side and the second side being symmetrically disposed about the axis of the second air duct 12. The first side is the side of the second air duct 12 close to the first air duct 11. The first opening 121 and the second opening 122 are formed in the circumferential wall of the assembly end, the first opening 121 and the second opening 122 are communicated with the end face of the assembly end, stress release can be facilitated through the design, the end face cracking risk is reduced, and meanwhile the assembly difficulty of the second air duct 12 and the exhaust pipe 22 is reduced. The first opening 121 is located on the first side, the second opening 122 is located on the second side, and the symmetrical arrangement can balance stress distribution, so that deformation risk of the second air duct 12 is reduced.
In the circumferential direction of the second air duct 12, the first opening 121 has a first width, and the second opening 122 has a second width. The first width is greater than the second width. The first width is larger, so that the second air duct 12 is prevented from being influenced by the gravity center of the first air duct 11 to generate asymmetric load so as to cause deflection displacement, and stress concentration is reduced.
In the axial direction of the second air duct 12, the size of the first opening 121 is a first length, and the size of the second opening 122 is a second length. The first length is less than the second length. The width of the first opening 121 is larger, so that the gravity center deflection displacement during the swinging of the second air duct 12 can be avoided, the second air duct 12 is allowed to swing to a certain extent towards one side close to the first air duct 11, and the acting force of the collision between the second air duct 12 and a vehicle during the swinging of the second air duct 12 is conducted to the position, away from the first side, of the second air duct 12. The second notch 122 has a longer length, so that the second air duct 12 can be inserted into the outer side of the exhaust pipe 22 to have sufficient deformation, and the purpose of convenient assembly is achieved. The length of the first opening 121 is shorter, so that the structure of the part of the second air duct 12 close to the upper side of the hoop 15 is complete, and no opening exists, thereby enhancing the strength of the part easy to break. The width of the second opening 122 is further narrower, so that the strength of the second air duct 12 can be further ensured.
In the present embodiment, as shown in fig. 1, the first width of the first notch 121 gradually increases in the direction of the fitting end. By gradually widening the design, the vibration stress transmitted to the second air duct 12 by the vehicle can be further transmitted to a part far away from the first side, so that the stress is prevented from concentrating on the first side, and the durability of the second air duct 12 is improved.
In this embodiment, as shown in fig. 1, guide fillets are respectively disposed on two sides of the opening of the first opening 121. In this way, the stress distribution is guided by the guide fillets during vehicle vibration, reducing localized stress concentrations. Meanwhile, the direction of the stress is guided by the guide fillets to dynamically change, so that stress concentration is further reduced. The diameter of the guiding fillet is larger than 15% of the diameter of the second air duct 12. The guide fillet effect of big radian is better, can enlarge the guide scope through increasing the fillet diameter, further prevents stress concentration to strengthen anti vibration performance.
In this embodiment, as shown in fig. 1 and 6, the second air duct 12 further has a third side and a fourth side along its circumferential direction. The third side and the fourth side are symmetrically arranged about the axis of the second air duct 12, and the symmetrical arrangement can keep the stress balance. The first side, the third side, the second side, and the fourth side are disposed in order along the circumferential direction of the second barrel 12. A third opening 123 is formed in the third side of the assembly end, and the third opening 123 penetrates through to the end face of the assembly end. A fourth opening 124 is formed on the fourth side of the assembly end, and the fourth opening 124 penetrates through to the end face of the assembly end. The third notch 123 and the fourth notch 124 are formed, the number of the notches is increased, and meanwhile, the end face constraint of the assembly end can be reduced through the design.
The third notch 123 forms an included angle of more than 0 ° with the axis of the second air duct 12 along the extending direction of the barrel body of the second air duct 12. The fourth notch 124 forms an included angle of more than 0 ° with the axis of the second air duct 12 along the extending direction of the barrel of the second air duct 12. By opening the third opening 123 and the fourth opening 124, the variable quantity of the assembly end is increased, the assembly smoothness of the second air duct 12 and the air outlet is improved, and the assembly resistance is reduced.
In this embodiment, as shown in fig. 9, the end of the second air duct 12 connected to the first air duct 11 is a connection end. The third opening 123 is inclined toward the second side toward the end of the connection end, and the fourth opening 124 is inclined toward the second side toward the end of the connection end. Through the inclination direction of third opening 123 and fourth opening 124, can be with the comparatively easy first side that takes place stress concentration, the guide stress extends towards the second side to disperse first side stress, and then strengthen the intensity of assembly end.
In this embodiment, as shown in fig. 9, in the circumferential direction of the second air duct 12, the third opening 123 has a third width, and the fourth opening 124 has a fourth width. The third width is smaller than the second width, and the fourth width is smaller than the second width. By reducing the third and fourth widths, the area between the first and third sides is prevented from undersizing the end face near the mounting end, resulting in stress concentrations. Therefore, the width is reduced, so that the enough strength of the end surface area can be ensured, and the cracking risk is reduced.
In this embodiment, as shown in fig. 6 and 7, one end of the second air duct 12 connected to the first air duct 11 is a connection end. The end of the third opening 123 pointing towards the connection end is inclined towards the first side, and the end of the fourth opening 124 pointing towards the connection end is inclined towards the first side. Through the slope design of third opening 123, fourth opening 124, carry out the bradyseism with the deformation of third opening 123, fourth opening 124 to absorb vibration energy, reduce structural fatigue.
In this embodiment, as shown in fig. 6, 7 and 8, the fitting end is provided with a first flaring slot 125 and a second flaring slot 126. One end of the third opening 123 pointing to the connecting end is communicated with the first flaring slot 125, and one end of the fourth opening 124 pointing to the connecting end is communicated with the second flaring slot 126. The diameter of the first flared groove 125 is greater than the width of the third opening 123, and the diameter of the second flared groove 126 is greater than the width of the fourth opening 124. Through the design of the first flaring groove 125 and the second flaring groove 126 and the enlarged diameter, the deformation quantity of the first flaring groove 125 and the second flaring groove 126 during the shock absorption can be increased, so that the stress is absorbed more effectively, and the shock resistance is improved. If the end of the third opening 123 pointing to the connection end and the end of the fourth opening 124 pointing to the connection end are set to be right angles, stress concentration at the right angles will be caused.
In this embodiment, as shown in fig. 6 and 7, in the axial direction of the second air duct 12, the third opening 123 has a third length, and the fourth opening 124 has a fourth length. The third length is greater than the first length and the fourth length is greater than the first length. By the longer third length and fourth length, the amount of deformation during assembly is increased, thereby facilitating the sleeve of the assembly end on the exhaust pipe 22 and improving the assembly efficiency.
In other embodiments, exhaust spool piece assembly 10 further includes insulation spool 13, buffer collar, exhaust vents 14. The heat insulation cylinder 13 is cylindrical, the heat insulation cylinder 13 is sleeved on the outer peripheral wall of the second air duct 12, and a gap is reserved between the heat insulation cylinder 13 and the second air duct 12. The heat insulation cylinder 13 can avoid scalding people. The exhaust hole 14 is arranged at one side of the heat insulation cylinder 13 near the assembly end, and because a gap is formed between the heat insulation cylinder 13 and the second air guide cylinder 12, moisture in air can be evaporated when the second air guide cylinder 12 is at high temperature, and after the second air guide cylinder 12 is cooled, the moisture can flow to the exhaust hole 14 along the outer peripheral wall of the second air guide cylinder 12 and the inner peripheral wall of the heat insulation cylinder 13, and the moisture is discharged through the exhaust hole 14. The buffer ring is sleeved at the assembly end, and the anchor ear 15 is sleeved at the peripheral wall of the buffer ring. The buffer ring absorbs external vibration or impact energy through self elastic deformation, and rigid collision between the anchor ear 15 and the second air duct 12 is avoided.
In this embodiment, the present invention provides a vehicle, as shown in FIG. 10, comprising a body assembly 20 and an exhaust spool assembly 10.
The vehicle body assembly 20 includes a vehicle body 21 and an exhaust pipe 22. The exhaust pipe 22 is detachably connected to the body 21, so that the installation and maintenance of the exhaust pipe 22 can be facilitated.
The assembly end of the second air duct 12 of the exhaust duct assembly 10 is sleeved outside the exhaust duct 22. The sleeved connection can realize the rapid assembly of the second air duct 12 and the exhaust pipe 22 and ensure the air tightness.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of implementing the disclosure, and that various changes in form and details may be made therein without departing from the scope of the disclosure.
